    This note summarizes the results obtained at injection during the 2nd MD block and the floating MD block in July. Highlights are presented for injection in the LHC with the Q20 SPS optics, influence of the supercycle and injection with 25 ns bunch spacing. Beams were successfully injected into the LHC using the Q20 optics [1, 3]. Small corrections were needed to steer the beam in the transfer lines. Dispersion measurements were conducted for both beams. The horizontal normalized dispersion in TI2 was a factor 2 smaller for Q20 with respect to Q26, for TI8 on the other hand the opposite was observed. The results for injection loss dependency on super cycle composition show only a small increase in losses for beam 2. The losses observed must therefore mainly come from other sources such as shot-by-shot stability or quality of scraping. For the injection with 25 ns bunch spacing bunches were injected for both beams. For B1 up to the maximum of 288 bunches. For B2 on the other only up to 144 bunches were injected...

    2003-01-01

    Molecular dynamic (MD) provided an ab initio simulation for nano-scale mechanical behavior of materials, provided that the inter-atomic potential is accurately prescribed. MD is particularly suitable in simulating the formation, the deformation, and the evolution of nanocrystals under a fast strain rate. To tackle large scale system and nano-seconds time duration, parallel algorithm is desired. The present paper reviews the recent advances in MD simulation for nanocrystals with attention focused on the applications toward nanomechanics. The examined issues are: formation of nanocrystalline metals, nanoindentation on nanocrystals, fast deformation of nanocrystals, orderdisorder transition, and nano-particle impact.

    Cholesterol is a structural component of cellular membranes, which is transported from liver to peripheral cells in the form of cholesterol esters (CE), residing in the hydrophobic core of low-density lipoprotein. Oxidized CE (OxCE) is often found in plasma and in atherosclerotic lesions of subjects with cardiovascular disease. Our earlier studies have demonstrated that OxCE activates inflammatory responses in macrophages via toll-like receptor-4 (TLR4). Here we demonstrate that cholesterol binds to myeloid differentiation-2 (MD-2), a TLR4 ancillary molecule, which is a binding receptor for bacterial lipopolysaccharide (LPS) and is indispensable for LPS-induced TLR4 dimerization and signaling. Cholesterol binding to MD-2 was competed by LPS and by OxCE-modified BSA. Furthermore, soluble MD-2 in human plasma and MD-2 in mouse atherosclerotic lesions carried cholesterol, the finding supporting the biological significance of MD-2 cholesterol binding. These results help understand the molecular basis of TLR4 activation by OxCE and mechanisms of chronic inflammation in atherosclerosis.

    Hadley, Richard F.

    This is a topical book that deals with the geomorphological and geological engineering problems associated with hillslope processes and sediment transport in the Los Angeles metropolitan area. There are few large cities in the United States where the problems of urban growth include such a distinctive physical environment, as well as the potential hazards of brush fires, earthquakes, and floods that occur in Los Angeles. The research and data used in the book are restricted to Los Angeles County and cover the period 1914-1978. The author has done a commendable job of synthesizing a large mass of data from diverse sources, including federal, state, and local agency reports, plus data from private groups such as professional technical societies and consultants.

    When the United States embarked on its effort to provide universal health insurance, the Canadian Medicare System was cited as a possible model for American health care. Often touted as an example of low-cost, high quality medicine, the Canadian system has mirrored the problems of health care across its southern border. With rocketing health care expenditures and financing having largely been decentralized to the individual provinces, local officials have struggled to cut costs and services. A central focus of these efforts has been a move to decrease the numbers of physicians, most notably a 10% decrease in medical school class size in 1993. While some Western provinces have experimented with the privatization of health care, the Canadian system still remains the epitome of government operated fee-for-service medicine. Given the likelihood of dramatic change in the American Medicare system, Canadian academic centers offer a unique perspective on the impact of capitation, evolving relationships with government payors, and the flip side of market oriented reforms. At the helm of one of Canada's largest schools is Arnold Aberman, MD, dean of the University of Toronto Faculty of Medicine. Born in Montreal, Quebec, Aberman received his MD from McGill University, but then did his residency both in Canada and the US, followed by a pulmonary fellowship at Albert Einstein College of Medicine and the Cardiovascular Research Institute of the University of California, San Francisco. Interviewed at his office in Toronto, Aberman reflected on the trials and tribulations confronting medicine on both sides of the 48th parallel.

    The fast beam losses in the order of 1 ms are expected to be a potential major luminosity limitation for higher beam energies after the LHC long shutdown (LS1). Therefore a Quench Test is planned in the winter 2013 to estimate the quench limit in this timescale and revise the current models. This experiment was devoted to determination the LHC Transverse Damper (ADT) as a system for fast losses induction. A non-standard operation of the ADT was used to develop the beam oscillation instead of suppressing them. The sign flip method had allowed us to create the fast losses within several LHC turns at 450 GeV during the previous test (26th March 2012). Thus, the ADT could be potentially used for the studies of the UFO ("Unidentied Falling Object") impact on the cold magnets. Verification of the system capability and investigations of the disturbed beam properties were the main objectives of this MD. During the experiment, the pilot bunches of proton beam were excited independently in the horizontal and vertical ...

    The purpose of this MD is to measure the octupole current thresholds for stability for a single bunch, and then make an immediate comparison (with the same operational settings) for a train of 72 bunches separated by 25ns. From theory, the expected thresholds should be similar. Any discrepancy between the two cases will be of great interest as it could indicate the presence of additional mechanisms that contribute to the instability threshold, for example electron cloud.

  10. Cavity Voltage Phase Modulation MD

    CERN Document Server

    Mastoridis, Themistoklis; Molendijk, John; Timko, Helga; CERN. Geneva. ATS Department

    2016-01-01

    The LHC RF/LLRF system is currently configured for extremely stable RF voltage to minimize transient beam loading effects. The present scheme cannot be extended beyond nominal beam current since the demanded power would exceed the peak klystron power and lead to saturation. A new scheme has therefore been proposed: for beam currents above nominal (and possibly earlier), the cavity phase modulation by the beam will not be corrected (transient beam loading), but the strong RF feedback and One-Turn Delay feedback will still be active for loop and beam stability in physics. To achieve this, the voltage set point will be adapted for each bunch. The goal of this MD was to test a new algorithm that would adjust the voltage set point to achieve the cavity phase modulation that would minimize klystron forward power.

    2011-01-01

    Policies promoting informal venture capital generally and business angel networks (BANs) in particular have gained increased attention in recent years. As a consequence, BANs are now widespread across Europe. However, there continues to be a debate whether BANs should be supported with public money....... This article discusses the possible rationale for governments to support BANs and what criteria to apply when evaluating such networks. The article is based on an in-depth observation study of the whole life cycle of a national BAN – the Danish Business Angel Network (DBAN) – and a comparison with a similar...... national angel network in Wales. Results show that applying traditional evaluation criteria for assessing BANs may provide only a partial picture. DBAN was squeezed between political pressures, impatience and lack of understanding of the broader benefits of an angel network. It was therefore left to die...

    In 2012, 22 days of beam time will be allocated for LHC MDs. In this paper, after recalling the 2011 LHC MD experience, the MD rrequests for 2012 are reviewed. Three primary MD themes for 2012 can be identified: 1)pushing performance in 2012, 2)preparing for 2014/15, and 3)towards maximum luminosity. Example topics include emittance growth in collision or enhanced satellites for theme 1), 25 ns operation for 2), and ATS optics for 3). Structures lists of MD requests and topics for each theme as well as some initial thoughts on the MD priorities are presented. For certain topics, "start-of-fill MDs" are proposed in order to most efficiently use of the available beam time.

  3. New Message Differences for Collision Attacks on MD4 and MD5

    Science.gov (United States)

    Sasaki, Yu; Wang, Lei; Kunihiro, Noboru; Ohta, Kazuo

    In 2005, collision resistance of several hash functions was broken by Wang et al. The strategy of determining message differences is the most important part of collision attacks against hash functions. So far, many researchers have tried to analyze Wang et al.'s method and proposed improved collision attacks. Although several researches proposed improved attacks, all improved results so far were based on the same message differences proposed by Wang et al. In this paper, we propose new message differences for collision attacks on MD4 and MD5. Our message differences of MD4 can generate a collision with complexity of less than two MD4 computations, which is faster than the original Wang et al.'s attack, and moreover, than the all previous attacks. This is the first result that improves the complexity of collision attack by using different message differences from Wang et al.'s. Regarding MD5, so far, no other message difference from Wang et al.'s is known. Therefore, study for constructing method of other message differences on MD5 should be interesting. Our message differences of MD5 generates a collision with complexity of 242 MD5 computations, which is slower than the latest best attack. However, since our attack needs only 1 bit difference, it has some advantages in terms of message freedom of collision messages.

  6. "Angels & Demons" - Distinguishing truth from fiction

    CERN Multimedia

    2005-01-01

    Dan Brown's best-selling novel "Angels & Demons" was published in French on 2 March. A web page on CERN's public site is dedicated to separating truth from fiction in this novel. After the extraordinary success of Dan Brown's "Da Vinci Code", one of his earlier novels "Angels & Demons", published in 2000, has now become a best seller and has generated a flood of questions about CERN. This detective story is about a secret society, the Illuminati, who wish to destroy the Vatican with an antimatter bomb stolen from - wait for it - CERN! Inevitably, CERN has been bombarded with calls about the technologies described in the novel that are supposed to be under development in the Laboratory. The Press Office has always explained that, even if the novel appears to be very informative, it is in fact a mixture of fact and fiction. For instance, according to the novel CERN is supposed to own a plane that can cover the distance between Massachusetts in the United States and Switzerland in just over an hour! ...

  10. The Role and Place of Governing Angels in Bible

    Directory of Open Access Journals (Sweden)

    Sayyed hesam aldin Hosseini

    2014-09-01

    Full Text Available Angels have allocated a considerable part of Bible's discussions to themselves and since one of the dogmatic principles of the revealed religions is the belief in angels, depiction of the place and attributes of angels can be the indicator of the quality of attitude and worldview and the strength of dogmatic principles of Bible's followers and justify their thought and ideas; For this subject is related with the issues such as: transcendent unity of divine acts and essence and attributes and even unity in obedience, how to record the actions and investigate them in Purgatory and Resurrection and believe in the unseen world and how to connect to that world and how to manage the world by God and the definition of the Kingdom of Heaven and how to divide people's sustenance and their reward and punishment which is the indicator and representative of the position of each religion as compared to other religions. Like Muslims, the followers of Bible regard the existence of angels as one of the articles of faith and among the most important elements of the world of being. And whereas the Old Testament has described the revelation of One God using figures who appear in the Eastern mythological stories, it can be seen that in many cases the Kingdom of Heaven has been depicted by metaphors which match the similes used in Quran like angel's march before God (Fajr, 22 as if God is one of the kings from East. The angels are mentioned a lot in the Bible. In Hebrews it has been said that the numbers of angels is countless and in fact, they cannot be enumerated. Angels also do many things including: the report of the Birth of John… the most important task which is assigned to the angels is worshipping God. (1 Enoch, 40 The other significant task undertaken by angels is mediating between God and man. Intercession is another role assigned to angels. (1 Enoch, 2: 4, 4:9 Sometimes man asks the angels beseechingly to convey his/her request to Divinity. The angels

  12. The angel flap for nipple reconstruction.

    Science.gov (United States)

    Wong, Wendy W; Hiersche, Matthew A; Martin, Mark C

    2013-01-01

    Creation of an aesthetically pleasing nipple plays a significant role in breast reconstruction as a determining factor in patient satisfaction. The goals for nipple reconstruction include minimal donor site morbidity and appropriate, long-lasting projection. Currently, the most popular techniques used are associated with a significant loss of projection postoperatively. Accordingly, the authors introduce the angel flap, which is designed to achieve nipple projection with lasting results. The lateral edges of the flap and the area surrounding the top of the nipple are de-epithelialized and the flaps are wrapped to create a nipple mound composed primarily of dermis. Decreasing the amount of fat within core of the nipple and enhancing dermal content promotes long-lasting projection. Furthermore, the incision pattern fits within a desired areolar size, preventing unnecessary superfluous extension of the incisions. Thus, the technique described herein achieves the goals of nipple reconstruction, including adequate and long-lasting projection, without extension of the lateral limb scars.

  16. Direct NOE simulation from long MD trajectories

    Science.gov (United States)

    Chalmers, G.; Glushka, J. N.; Foley, B. L.; Woods, R. J.; Prestegard, J. H.

    2016-04-01

    A software package, MD2NOE, is presented which calculates Nuclear Overhauser Effect (NOE) build-up curves directly from molecular dynamics (MD) trajectories. It differs from traditional approaches in that it calculates correlation functions directly from the trajectory instead of extracting inverse sixth power distance terms as an intermediate step in calculating NOEs. This is particularly important for molecules that sample conformational states on a timescale similar to molecular reorientation. The package is tested on sucrose and results are shown to differ in small but significant ways from those calculated using an inverse sixth power assumption. Results are also compared to experiment and found to be in reasonable agreement despite an expected underestimation of water viscosity by the water model selected.

  18. Batch By Batch Longitudinal Emittance Blowup MD

    CERN Document Server

    Mastoridis, T; Butterworth, A; Jaussi, M; Molendijk, J

    2012-01-01

    The transverse bunch emittance increases significantly at 450 GeV from the time of injection till the ramp due to IBS. By selectively blowing up the longitudinal emittance of the incoming batch at each injection, it should be possible to reduce the transverse emittance growth rates due to IBS. An MD was conducted on April 22nd 2012 to test the feasibility and performance of the batch-by-batch longitudinal emittance blowup. There were three main goals during the MD. First, to test the developed hardware, firmware, and software for the batch-by-batch blowup. Then, to measure the transverse emittance growth rates of blown-up and "witness" batches to quantify any improvement, and finally to test the ALLInjectSequencer class, which deals with the complicated gymnastics of introducing or masking the new batch to various RF loops.

    2012-01-01

    UFOs ("Unidentified Falling Objects") are expected to be one of the major known performance limitation of the LHC. In this MD, the production mechanism and the dynamics of UFOs at the injection kicker magnets (MKIs) and the tune kicker magnets (MKQs) were studied. This was done by pulsing the MKIs and MKQs on a gap in the partly filled machine. During the MD, in total 58 UFO-type beam loss patterns were observed directly after pulsing the MKIs. None were observed after pulsing the MKQs, which provides important input for possible mitigation strategies. The temporal and spatial distribution of the UFO events could be determined by using a dedicated BLM Study Buffer, the implications for the UFO dynamics are discussed.

    We have developed parallel computation codes for a classical molecular dynamics (MD) method. In order to use them on work station clusters as well as parallel super computers, we use MPI (message passing interface) library for distributed-memory type computers. Two algorithms are compared: (1) particle parallelism technique: easy to install, effective for rather small number of processors. (2) region parallelism technique: take some time to install, effective even for many nodes. (J.P.N.)

    2012-05-01

    Full Text Available Angelic appearances function prominently in the birth narratives of Matthew. An angel of the Lord appears to Joseph (Mt. 1:20; 2:12, 13, 19 and 22. Besides these explicit references to the angel, the first Gospel also refers to the guidance by an “unusual” star (Mt. 2:1-2 and 9-10. The appearance of the angel of the Lord to Joseph is investigated within the context of such appearances in New Testament times. Furthermore, the appearance of the star is investigated in the light of the views of stars in that period of time. The goal is to establish the nature of these appearances and the relation between them.

    Two unique datasets on the abundance and morphology of the angel lichen moth ( Cisthene angelus) in Grand Canyon, Arizona, USA were compiled to describe the phenology and life history of this common, but poorly known, species. The abundance data were collected from 2012 to 2013 through a collaboration with river runners in Grand Canyon National Park. These citizen scientists deployed light traps from their campsites for one hour each night of their expedition. Insects were preserved in ethanol on site, and returned to the Southwest Biological Science Center in Flagstaff, Arizona for analysis in the laboratory. A total of 2,437 light trap samples were sorted through, 903 of which contained C. angelus. In total, 73,841 C. angelus were identified and enumerated to create the abundance data set. The morphology dataset is based on a subset of 28 light trap samples from sampling year 2012 (14 from spring and 14 from fall.) It includes gender and forewing lengths for 2,674 individual moths and dry weights for 1,102 of those individuals.

    2016-05-01

    ProtoMD is a toolkit that facilitates the development of algorithms for multiscale molecular dynamics (MD) simulations. It is designed for multiscale methods which capture the dynamic transfer of information across multiple spatial scales, such as the atomic to the mesoscopic scale, via coevolving microscopic and coarse-grained (CG) variables. ProtoMD can be also be used to calibrate parameters needed in traditional CG-MD methods. The toolkit integrates 'GROMACS wrapper' to initiate MD simulations, and 'MDAnalysis' to analyze and manipulate trajectory files. It facilitates experimentation with a spectrum of coarse-grained variables, prototyping rare events (such as chemical reactions), or simulating nanocharacterization experiments such as terahertz spectroscopy, AFM, nanopore, and time-of-flight mass spectroscopy. ProtoMD is written in python and is freely available under the GNU General Public License from github.com/CTCNano/proto_md.

    2012-01-01

    Beam halo measurements in the LHC were conducted through collimator scrapings in an MD carried out on the 22nd June 2012 for the first time at 4 TeV. The time evolution of losses during a collimator scan provides information on halo diffusion and population. Four scans were performed with two collimators in the vertical and horizontal plane in B1 and B2 respectively, before and after bringing the beams into collisions. During an inward step, the beam losses measured at the BLMs for the first 3 seconds are believed to be dominated by multi-turn halo removal by the collimator jaw. However, a good comparison was found between fits of the diffusion model and the subsequent loss decay. In addition, the fitted diffusion coefficients compare well to the coefficients estimated from the core emittance growth rates as a function of action.

    Instabilities were being routinely observed in B1V during ADJUST. The timing of the instabilities has been localised to shortly after the TOTEM bump has been implemented. The result is emittance blowup which can negatively effect the luminosity output of the fill. This MD aimed to rule out possible sources of the instability (i.e. beam-beam effects or electron cloud) by only taking one single beam to 6.5TeV and going through the full machine cycle. After the implementation of the TOTEM bump, a reduction of the octupole current was performed in order to determine if there was a discrepancy in the threshold between simulations and measurement. As a precursor, the results of the End of Fill MD: Validation of Single Bunch Stability Threshold will also be described.

    2005-08-01

    Leroy D Vandam, MD was a remarkable man--an intricate amalgamation of an artist, scientist, and physician. He was a bastion of medical historical knowledge. Dr Vandam became a most influential anesthesiologist, some say, a giant. He was an example of someone who, with resolve, overcame adversity. His artwork is displayed in countless places, and several of his paintings form part of the Wood Library Museum Heritage Series. Dr Vandam was first a surgeon, but he abandoned surgery and pursued a career in anesthesiology under the leadership of Robert Dripps. He completed his residency training at the University of Pennsylvania and joined its staff in 1949. When he arrived at Brigham and Women's Hospital in the 1950s as director of anesthesia, he embarked on one of the most illustrious careers in American anesthesiology. Dr Vandam published more than 250 original articles, chapters, abstracts, and other reports on a wide variety of subjects including history, art, and pharmacology. His classic article on the complications of neuroaxial blocks is a seminal work in anesthesiology. This article describes how an anesthesiologist who shared an interest with Dr Vandam in the history of anesthesiology came to produce a movie based on his career, the evolution of anesthesia equipment, and the transformation of our specialty.

    Vertex reconstruction is not accurate enough for LHCb when the bunch length in physics shrinks below about 0.9 ns. The end-of-fill MD studies presented here proved that bunch flattening using sinusoidal RF modulation is a loss-free method to increase the r.m.s. bunch length and flatten the bunch profile. Furthermore, the optimum modulation parameters to be used in physics have been identified. Subsequently, bunch flattening in physics was used operationally with a modulation frequency of 98.75 % of the central synchrotron frequency and 0.6 modulation amplitude, resulting in a 150-200 ps increase in the BQM-measured bunch length. A ‘mid-of-fill’ test at arrival to flat top revealed that also the bunch distribution created by the controlled emittance blow-up during the ramp is affected when bunch flattening is applied. The measurements took place on 17th June and the 4th, 7th and 22nd July 2016. Operational cases are shown as well.

  1. Orbit Feedback Operation with RCBX (MD 1209)

    2017-01-01

    The LHC Orbit Feedback (OFB) is able to drive any orbit corrector circuit (COD) to steer the LHC orbit. But during the first feedback tests in 2010, all attempts to use the common triplet orbit correctors (MCBX) failed because the QPS system installed to protect those magnets triggered power aborts as soon as the OFB steered the beam with those CODs. The reason was most likely the violation of the RCBX circuit acceleration limits. For this reason the MCBX orbit correctors were never driven by the OFB in regular operation. Although the performance of the OFB is generally excellent, the quality of the beam steering around IRs could be improved if the OFB could correct the orbit with the MCBX to counteract locally triplet quadrupole movements. The aim of this MD was to make a new attempt to use the MCBX in the OFB. The test was successful at injection (no circuit trip) and failed during the ramp (QPS power abort). The PC voltages and QPS Ures signals revealed the presence of voltage spikes with a period of 10~s...

    Bonham, Ann C

    2014-01-01

    MD-PhD programs provide rigorous, integrated training for physician-scientists, enabling them to frame scientific questions in unique ways and to apply clinical insight to fundamental science. Few would question the influential contributions of MD-PhD physician-scientists in advancing medical science. In this issue of Academic Medicine, Jeffe et al affirm high levels of excellence in educational outcomes from MD-PhD training programs at U.S. MD-granting medical schools, especially programs that receive funding from the NIH Medical Scientist Training Program (MSTP). The author of this commentary observes that, in the face of current economic pressures, comprehensive, longitudinal national outcomes data from MSTP- and non-MSTP-funded MD-PhD programs will help verify the value provided by MD-PhD physician-scientists. She proposes that MD-PhD programs should better prepare the next generation of physician-scientists for future research environments, which will provide new technologies, venues, and modalities. These research environments will be more closely integrated within health care delivery systems, extend into diverse communities and regions, and employ complex technologies. MD-PhD physician-scientists also will train and gain expertise in broadening areas of research, such as health policy, health economics, clinical epidemiology, and medical informatics. Program leaders are ideally situated to foster innovative learning environments and methodologies. By sharing their innovations, they can help ensure production of a diverse MD-PhD physician-scientist workforce, prepared to engage in myriad research opportunities to meet patient and population needs in a new environment.

    This note highlights the results obtained during the third so-called ATS MD which took place in 2011. The goal of this MD was extremely challenging, targeting a pre-squeezed beta* of 40 cm in ATLAS and CMS, followed by a telescopic squeeze of these two insertions to finally reach a beta* of 10 cm both at IP1 and IP5. Due to the rather poor machine availability during the MD period, the time initially allocated to the ATS studies was hardly cut by a factor of 2, and "only" the achromatic pre-squeeze down to beta*=40 cm was demonstrated with beam.

    Tess of the D’urbervilles by Thomas Hardy has had a remarkably strong appeal for hundreds of thousands of readers for decades. Those who have read it always hold great sympathy for Tess and there have been many negative comments on the other hero – Angel Clare since this great works was created, most containing the idea that it is Angel that causes Tess’ whole tragedy. In my opinion, it is unfair to let Angel bear all the responsibilities. Virtually, to some extent, this novel is a description of the maturing course of modernism pioneer if a careful discussion of Angel Clare could be made.

    2015-10-01

    There are many areas of MD and HD vehicles that can be improved by new technologies and optimized control strategies. Component optimization and idle reduction need to be addressed, this is best done by a two part approach that includes selecting the best component technology, and/or architecture, and optimized controls that are vehicle focused. While this is a common focus in the light duty industry it has been gaining momentum in the MD and HD market as the market gets more competitive and the regulations become more stringent. When looking into systems optimization and idle reduction technologies, affected vehicle systems must first be considered, and if possible included in the new architecture to get the most benefit out of these new capabilities. Typically, when looking into idle reduction or component optimization for MD/HD, the vehicle s accessories become a prime candidate for electrification or hybridization. While this has already been studied on light duty vehicles (especially on hybrids and electric vehicles) it has not made any head way or market penetration in most MD and HD applications. If hybrids and electric MD and HD vehicles begin to break into the market this would be a necessary step into the ability to make those vehicles successful by allowing for independent, optimized operation separate from the engine.

  2. Interseismic Strain Accumulation Across Metropolitan Los Angeles: Puente Hills Thrust

    Twelve years of observation of the Southern California Integrated GPS Network (SCIGN) are tightly constraining the distribution of shortening across metropolitan Los Angeles, providing information on strain accumulation across blind thrust faults. Synthetic Aperture Radar Interferometry (InSAR) and water well records are allowing the effects of water and oil management to be distinguished. The Mojave segment of the San Andreas fault is at a 25° angle to Pacific-North America plate motion. GPS shows that NNE-SSW shortening due to this big restraining bend is fastest not immediately south of the San Andreas fault across the San Gabriel mountains, but rather 50 km south of the fault in northern metropolitan Los Angeles. The GPS results we quote next are for a NNE profile through downtown Los Angeles. Just 2 mm/yr of shortening is being taken up across the San Gabriel mountains, 40 km wide (0.05 micro strain/yr); 4 mm/yr of shortening is being taken up between the Sierra Madre fault, at the southern front of the San Gabriel mountains, and South Central Los Angeles, also 40 km wide (0.10 micro strain/yr). We find shortening to be more evenly distributed across metropolitan Los Angeles than we found before [Argus et al. 2005], though within the 95% confidence limits. An elastic models of interseismic strain accumulation is fit to the GPS observations using the Back Slip model of Savage [1983]. Rheology differences between crystalline basement and sedimentary basin rocks are incorporated using the EDGRN/EDCMP algorithm of Wang et al. [2003]. We attempt to place the Back Slip model into the context of the Elastic Subducting Plate Model of Kanda and Simons [2010]. We find, along the NNE profile through downtown, that: (1) The deep Sierra Madre Thrust cannot be slipping faster than 2 mm/yr, and (2) The Puente Hills Thrust and nearby thrust faults (such as the upper Elysian Park Thrust) are slipping at 9 ±2 mm/yr beneath a locking depth of 12 ±5 km (95% confidence limits

  3. Reconnaissance of geothermal resources of Los Angeles County, California

    Energy Technology Data Exchange (ETDEWEB)

    Higgins, C.T.

    1981-01-01

    Thermal waters produced from large oil fields are currently the most important geothermal resources in Los Angeles County. Otherwise, the County does not appear to have any large, near-surface geothermal resources. The oil fields produce thermal water because of both the moderate depths of production and normal to above-normal geothermal gradients. Gradients are about 3.0-3.5/sup 0/C/100 meters in the Ventura Basin and range from that up to about 5.5-6.0/sup 0/C/100 meters in the Los Angeles Basin. The hottest fields in the County are west of the Newport-Inglewood Structural Zone. The Los Angeles Basin has substantially more potential for uses of heat from oil fields than does the Ventura Basin because of its large fields and dense urban development. Produced fluid temperatures there range from ambient air to boiling, but most are in the 100-150/sup 0/F range. Daily water production ranges from only a few barrels at some fields to over a million barrels at Wilmington Oil Field; nearly all fields produce less than 50,000 barrels/day. Water salinity generally ranges from about 15,000-35,000 mg/liter NaCl. Fields with the most promise as sources of heat for outside applications are Wilmington, Torrance, Venice Beach, and Lawndale. The centralized treatment facilities are the most favorable sites for extraction of heat within the oil fields. Because of the poor water quality heat exchangers will likely be required rather than direct circulation of the field water to users. The best sites for applications are commercial-industrial areas and possibly institutional structures occupied by large numbers of people.

  4. CoMD Implementation Suite in Emerging Programming Models

    Energy Technology Data Exchange (ETDEWEB)

    2014-09-23

    CoMD-Em is a software implementation suite of the CoMD [4] proxy app using different emerging programming models. It is intended to analyze the features and capabilities of novel programming models that could help ensure code and performance portability and scalability across heterogeneous platforms while improving programmer productivity. Another goal is to provide the authors and venders with some meaningful feedback regarding the capabilities and limitations of their models. The actual application is a classical molecular dynamics (MD) simulation using either the Lennard-Jones method (LJ) or the embedded atom method (EAM) for primary particle interaction. The code can be extended to support alternate interaction models. The code is expected ro run on a wide class of heterogeneous hardware configurations like shard/distributed/hybrid memory, GPU's and any other platform supported by the underlying programming model.

    Full Text Available Among the issues about the angels considered by the Dominican preacher Giordano da Pisa, this essay studies the problem of their language. The question of the locutio angelica had become quite relevant in the scholastic thought from the XIIIth century and had been widely discussed by Thomas Aquinas and Giles of Rome; the study of this argument in Giordano da Pisa’s sermons shows the transition in the homiletic texts of a highly speculative theme and we can see how the preacher, who combines rather freely the positions of Thomas and Giles, filters the question for his lay public, simplifying the more difficult passages.

    Full Text Available Introduction: Career prospects in Pharmacology are witnessing a sea change due to fast and unanticipated development in the field of clinical research. Numerous openings exist now in academia, pharmaceutical industry, Clinical Research Organizations (CRO or as regulatory consultants, experimental pharmacologists, etc. In short, there are various options to choose from, depending on one′s interest. It′s high time we ponder now over the training programme for post-graduate students in Pharmacology. It needs to be revised keeping in mind the job prospects & uniqueness of the MD Pharmacology degree. Aim: To take suggestions of experienced pharmacologists on the present syllabus for MD Pharmacology and their opinion on continuation of Bioassay experiment which is currently an important part of it . Materials and Methods: A structured questionnaire was given to 30 experienced pharmacologists to seek their opinion on MD Pharmacology syllabus & continuation of Bioassay as a part of MD practical. Results: Out of 30 participants, 29 (96.6% did not use their knowledge of Bioassay during their 10 years of post MD career, whether in pharmaceutical industry or in academics. Only 5 of them (16.6% feel that experiment on bioassay should be continued in the current state. 76.7% of them wish it to be modified to a Dose Response Curve ( DRC . 6.71% feel that it should be totally scrapped. All the participants feel the need of revising current MD Pharmacology syllabus. Current syllabus is inclined more towards preparing good academicians but it lacks the proper training for creating good clinical research professionals. Medical writing, writing necessary documents for clinical trials including regulatory documents, writing an article for medical journals, marketing communication, product monograph and patient information of a clinical trial could be incorporated. They should be aware of the regulatory requirements for conducting studies on investigational drugs

    This note contains the preliminary results of the LHC MD that took place on 29-June-2011 (from 10 p.m. to 07 a.m.), dedicated to study Beam Current Monitors (BCT), Wire Scaners (WS), Synchrotron Radiation (BSRT), Beam Position (BPM), Wall Current (WCM) and Beam Gas Ionization (BGI) monitors. The MD aimed at performing different studies on the individual monitors. At the same time, it was possible to perform calibration studies with the Abort Gap (AGM) and Longitudinal Density (LDM) monitors that share the extracted light with the BSRT. Additionally some observations about the beam stability and emittance dependence on the chromaticity were performed.

    HIV continues to be a serious public health problem for men who have sex with women (MSW), especially homeless MSW. Although consideration of gender has improved HIV prevention interventions, most of the research and intervention development has targeted how women's HIV risk is affected by gender roles. The effect of gender roles on MSW has received relatively little attention. Previous studies have shown mixed results when investigating the association between internalization of masculine gender roles and HIV risk. These studies use a variety of scales that measure individual internalization of different aspects of masculinity. However, this ignores the dynamic and culturally constructed nature of gender roles. The current study uses cultural consensus analysis (CCA) to test for the existence of culturally agreed upon masculinity and gender role beliefs among homeless MSW in Los Angeles, as well as the relationship between these beliefs and HIV-related behaviors and attitudes. Interviews included 30 qualitative and 305 structured interviews with homeless MSW in Los Angeles's Skid Row area. Analysis identified culturally relevant aspects of masculinity not represented by existing masculinity scales, primarily related to barriers to relationships with women. Behaviors, attitudes, and knowledge related to HIV were significantly associated with men's level of agreement with the group about masculinity. The findings are discussed in light of implications for MSW HIV intervention development.

  14. Carotenoids of Sea Angels Clione limacina and Paedoclione doliiformis from the Perspective of the Food Chain

    2014-03-01

    Full Text Available Sea angels, Clione limacina and Paedoclione doliiformis, are small, floating sea slugs belonging to Gastropoda, and their gonads are a bright orange-red color. Sea angels feed exclusively on a small herbivorous sea snail, Limacina helicina. Carotenoids in C. limacina, P. doliiformis, and L. helicina were investigated for comparative biochemical points of view. β-Carotene, zeaxanthin, and diatoxanthin were found to be major carotenoids in L. helicina. L. helicina accumulated dietary algal carotenoids without modification. On the other hand, keto-carotenoids, such as pectenolone, 7,8-didehydroastaxanthin, and adonixanthin were identified as major carotenoids in the sea angels C. limacina and P. doliiformis. Sea angels oxidatively metabolize dietary carotenoids and accumulate them in their gonads. Carotenoids in the gonads of sea angels might protect against oxidative stress and enhance reproduction.

  15. Improved Collision Attack on Hash Function MD5

    Institute of Scientific and Technical Information of China (English)

    Jie Liang; Xue-Jia Lai

    2007-01-01

    In this paper, we present a fast attack algorithm to find two-block collision of hash function MD5.The algorithm is based on the two-block collision differential path of MD5 that was presented by Wang et al.In the Conference EUROCRYPT 2005.We found that the derived conditions for the desired collision differential path were not sufficient to guarantee the path to hold and that some conditions could be modified to enlarge the collision set.By using technique of small range searching and omitting the computing steps to check the characteristics in the attack algorithm, we can speed up the attack of MD5 efficiently.Compared with the Advanced Message Modification technique presented by Wang et al.,the small range searching technique can correct 4 more conditions for the first iteration differential and 3 more conditions for the second iteration differential, thus improving the probability and the complexity to find collisions.The whole attack on the MD5 can be accomplished within 5 hours using a PC with Pentium4 1.70GHz CPU.

  13. Immigrant incorporation in the garment industry of Los Angeles.

    Light, I; Bernard, R B; Kim, R

    1999-01-01

    This study expands immigrant social network theory and examined employment patterns in the garment industry in Los Angeles, California, among Latino workers employed by Asian immigrant entrepreneurs. The study determined that a large percentage of immigrant employees found their jobs through the immigrant economy. Entrepreneurship increased the supply of local jobs and expanded the economy at destination at no expense to natives. Immigrant entrepreneurs bought firms from nonimmigrant owners or started new ones with an immigrant labor supply. Massey's index is flawed due to its exclusion of the role of entrepreneurs. Migration networks facilitate entrepreneurship, but some ethnic groups have fewer entrepreneurs, such as Mexicans and Central Americans. A 1993 Los Angeles survey identified 3642 garment factories in its county. Mean employment was 27.1 persons. The garment industry was the 4th largest industry in the area in 1996, with 98,700 employees. It represented 6% of all wage and salary employees in the City and 5.5% of the immigrant labor force in the County in 1990. 93% of garment workers in 1990 were immigrants. It is estimated that 51% of garment factory owners were Asians; most employees were Latinos. Census figures on sewing machine operators indicated 47.3% of owners were Whites and 42.45 were Asians. 53.3% of employees were other ethnic groups, 14.5% were Asians, and 32.2% were Whites. It is estimated that 47.2% of total employment was due to the immigration economy. 71.5% of the total employment in the garment industry was in the immigrant sector.

  14. Apple fruit copper amine oxidase isoforms: peroxisomal MdAO1 prefers diamines as substrates, whereas extracellular MdAO2 exclusively utilizes monoamines.

    4-Aminobutyrate (GABA) accumulates in apple fruit during controlled atmosphere storage. A potential source of GABA is the polyamine putrescine, which can be oxidized via copper-containing amine oxidase (CuAO), resulting in the production 4-aminobutanal/Δ(1)-pyrroline, with the consumption of O2 and release of H2O2 and ammonia. Five putative CuAO genes (MdAO genes) were cloned from apple (Malus domestica Borkh. cv. Empire) fruit, and the deduced amino acid sequences found to contain the active sites typically conserved in CuAOs. Genes encoding two of these enzymes, MdAO1 and MdAO2, were highly expressed in apple fruit and selected for further analysis. Amino acid sequence analysis predicted the presence of a C-terminal peroxisomal targeting signal 1 tripeptide in MdAO1 and an N-terminal signal peptide and N-glycosylation site in MdAO2. Transient expression of green fluorescent fusion proteins in Arabidopsis protoplasts or onion epidermal cells revealed a peroxisomal localization for MdAO1 and an extracellular localization for MdAO2. The enzymatic activities of purified recombinant MdAO1 and MdAO2 were measured continuously as H2O2 production using a coupled reaction. MdAO1 did not use monoamines or polyamines and displayed high catalytic efficiency for 1,3-diaminopropane, putrescine and cadaverine, whereas MdAO2 exclusively utilized aliphatic and aromatic monoamines, including 2-phenylethylamine and tyramine. Together, these results indicate that MdAO1 may contribute to GABA production via putrescine oxidation in the peroxisome of apple fruit under controlled atmosphere conditions. MdAO2 seems to be involved in deamination of 2-phenylethylamine, which is a step in the biosynthesis of 2-phenylethanol, a contributor to fruit flavor and flower fragrance.

    The Beam Transfer Function (BTF) measurements have been previously tested in the LHC during MD block 1 and 2. Different machine configurations (i.e. energy, beam intensity, emittance etc...) have been tested to determine a safe set-up (excitation amplitude) of the system to be completely transparent to the beam (no emittance blow-up neither losses). The aim of this experiment in MD block 3 was to characterize the Stability Diagram (SD) in the presence of diffusion mechanisms induced by excited resonances due to beam-beam long range and Landau octupole interplay. During the experiment, BTF measurements have been acquired at flat top for different settings of Landau octupole current, different chromaticity values and transverse feedback gains. In this note the description of the experiment is presented together with some preliminary results.

    MD210 aims for the creation of longitudinally hollow bunches in the CERN PS Booster. The first three sessions have been carried out using the radial loop feedback system in order to drive the beam on a dipolar parametric resonance (instead of the phase loop). It has been found that the damping by the phase loop inhibits the excitation of the resonance to a major extent. The hollow distributions generated under these circumstances fail to reach a satisfying bunching factor. Nonetheless, proving the principally successful application of this technique to the PS Booster promises good results once the phase loop system supports trim functions. The approach, actions and detailed results of the first three MD sessions are presented in this paper.

    The sufficient conditions for keeping desired differential path of MD5 was discussed. By analyzing the expanding of subtraction difference, differential characters of Boolean functions, and the differential characters of shift rotation, the sufficient conditions for keeping desired differential path could be obtained. From the differential characters of shift rotation, the lacked sufficient conditions were found. Then an algorithm that reduces the number of trials for finding collisions were presented. By restricting search space, search operation can be reduced tc 234 for the first block and 230 for the second block. The whole attack on the MD5 can be accomplished within 2C hours using a PC with 1.6 G CPU.

    The purpose of this MD is to measure the octupole current threshold to reach single-bunch stability in the LHC at flat top. Two bunches with dierent emittances are injected in the LHC in both B1 and B2 and the current in the Landau octupoles was progressively decreased until an instability developed. The measurements provide insight into the LHC impedance model by comparing them with the stabilizing octupole current predicted from DELPHI.

    Classicists have argued that angels in Christian theology were modeled on the eunuchs of antiquity; with angels providing the same services to the Lord in Heaven that eunuchs provided to emperors on Earth. I apply this idea toward understanding the cherubim on the ark in Exodus 25 and the death of Aaron's sons in Leviticus 10. I also suggest that the angel-eunuch analogy can help us understand the psychological impact of androgen deprivation therapy on modern prostate cancer patients. Appreciating this analogy can help prostate cancer patients accept and adapt to the changes they experience.

    2012-07-01

    Full Text Available Angel investors are very important for small and medium sized enterprises because they provide more than money. They are hands-on investors and contribute their skills, expertise, knowledge and contacts in the businesses they invest in. They are wealthy persons with great business experience. They are willing to invest and offer their wealth and knowledge to owners of small and medium sized enterprises and to entrepreneurs to start or develop their businesses. One of the attributes of angel investors is that they like to remain anonymus. Due to this attribute, a lot of ideas can not be accomplished. To eliminate this, many countries establish angel investor syndicates (groups and networks. These syndicates (groups and networks facilitate the process of matching entrepreneurs and angel investors.

    Institute of Scientific and Technical Information of China (English)

    WANG Li; HE Shunping; CHEN Yiyu

    2007-01-01

    Angel-related element belongs to the family of miniature inverted-repeat transposable elements (MITEs). In this paper we report the identification of an Angel- related element in the series Leuciscini of cyprinid fishes, which is located in the second intron of the growth hormone (GH) gene. We have also found that this element is absent in orthologous locus in the series Barbini of cyprinid fishes, that provides new evidence for the monophyly of the series Leuciscini. The insertion of Angel-related element into the GH gene might take place in the common ancestor of the series Leuciscini after its divergence from the series Barbini. The high sequence divergence and relatively broad species distribution of Angel-related elements implies that they might be ancient transposons which appeared about 26 million years ago.

  6. Transpiration of urban forests in the Los Angeles metropolitan area.

    Science.gov (United States)

    Pataki, Diane E; McCarthy, Heather R; Litvak, Elizaveta; Pincetl, Stephanie

    2011-04-01

    Despite its importance for urban planning, landscape management, and water management, there are very few in situ estimates of urban-forest transpiration. Because urban forests contain an unusual and diverse mix of species from many regions worldwide, we hypothesized that species composition would be a more important driver of spatial variability in urban-forest transpiration than meteorological variables in the Los Angeles (California, USA) region. We used constant-heat sap-flow sensors to monitor urban tree water use for 15 species at six locations throughout the Los Angeles metropolitan area. For many of these species no previous data on sap flux, water use, or water relations were available in the literature. To scale sap-flux measurements to whole trees we conducted a literature survey of radial trends in sap flux across multiple species and found consistent relationships for angiosperms vs. gymnosperms. We applied this relationship to our measurements and estimated whole-tree and plot-level transpiration at our sites. The results supported very large species differences in transpiration, with estimates ranging from 3.2 +/- 2.3 kg x tree(-1) x d(-1) in unirrigated Pinus canariensis (Canary Island pine) to 176.9 +/- 75.2 kg x tree(-1) x d(-1) in Platanus hybrida (London planetree) in the month of August. Other species with high daily transpiration rates included Ficus microcarpa (laurel fig), Gleditsia triacanthos (honeylocust), and Platanus racemosa (California sycamore). Despite irrigation and relatively large tree size, Brachychiton populneas (kurrajong), B. discolor (lacebark), Sequoia sempervirens (redwood), and Eucalyptus grandis (grand Eucalyptus) showed relatively low rates of transpiration, with values < 45 kg x tree(-1) x d(-1). When scaled to the plot level, transpiration rates were as high as 2 mm/d for sites that contained both species with high transpiration rates and high densities of planted trees. Because plot-level transpiration is highly

    2001-01-01

    Experiment of the molecular deposition (MD) films with and without alkyl terminal de-posited on the silicon wafer were conducted by using nanoindentation. It was found that MD filmsand alkyl terminated MD films exhibit higher critical load (scratch resistance or adhesive strength)and lower coefficient of friction compared with the silicon substrate. Critical load (scratch resis-tance) increases with the number of layers, and coefficients of friction of those MD film with alkylterminal are still best for the same layer of MD film.

    Barreiro, S.; Rua, J.; Tomé, M.

    2016-07-01

    Aim of the study. The existing stand level forest simulators available in Portugal were not developed with the aim of including up-to-date model versions and were limited in terms of accounting for forest management. The simulators’ platform, sIMfLOR was recently created to implement different growth models with a common philosophy. The objective was developing one easily-updatable, user-friendly, forest management and climate change sensitive simulator capable of projecting growth for the main tree species in Portugal. Area of the study: Portugal. Material and methods: The new simulator was programmed in a modular form consisting of several modules. The growth module integrates different forest growth and yield models (empirical and process-based) for the main wood production tree species in Portugal (eucalypt, umbrella and maritime pines); whereas the management module drives the growth projections along the planning horizon according to a range of forest management approaches and climate (at present only available for eucalypt). Main results: The main result is the StandsSIM-MD Management Driven simulator that overcomes the limitations of the existing stand level simulators. It is a step forward when compared to the models currently available in the sIMfLOR platform covering more tree species, stand structures and stand compositions. It is focused on end-users and it is based on similar concepts regarding the generation of required inputs and generated outputs. Research highlights: Forest Management Driven simulations approach. Multiple Prescriptions-Per-Stand functionality. StandsSIM-MD can be used to support landowners decisions on stand forest management. StandsSIM-MD simulations at regional level can be combined with optimization routines. (Author)

  10. A Secure Hash Function MD-192 With Modified Message Expansion

    CERN Document Server

    Tiwari, Harshvardhan

    2010-01-01

    Cryptographic hash functions play a central role in cryptography. Hash functions were introduced in cryptology to provide message integrity and authentication. MD5, SHA1 and RIPEMD are among the most commonly used message digest algorithm. Recently proposed attacks on well known and widely used hash functions motivate a design of new stronger hash function. In this paper a new approach is presented that produces 192 bit message digest and uses a modified message expansion mechanism which generates more bit difference in each working variable to make the algorithm more secure. This hash function is collision resistant and assures a good compression and preimage resistance.

  11. Geologic seepage of methane and light alkanes in Los Angeles

    Natural geologic seepage of methane from underground oil and natural gas reservoirs has been suggested to be an underreported part of the global methane budget. Other light alkanes are also given off in combination with the methane seepage, making it possible that geologic seepage is also a potentially significant global source of these light alkanes. This study reports C1-C5 findings from geologic seepage made in the Los Angeles region. Microseepage, invisible escape of gases, was measured primarily at Kenneth Hahn Regional Park, while macroseepage, the visible release of gases, was measured at the La Brea Tar Pits. Samples were collected using stainless steel canisters and flux chambers and were analyzed using gas chromatography with flame ionization detectors (GC-FID). Average microseepage flux rates of 0.95 μg m-2 h-1 for ethane and 0.51 μg m-2 h-1 were found for propane, while average macroseepage rates for methane, ethane, and propane were 664, 19.8, and 18.1 mg m-2 h-1 respectively. Relationships between microseepage flux rate and location of underground oil and natural deposit and earthquake fault lines are presented. Additionally, the relative importance of findings in context with global budgets and local air quality is discussed.

  12. Formation of Los Angeles's low density and high car dependence

    2009-01-01

    As a typical car-dependent city, Los Angeles (LA) is extensively used as an example in research to illustrate car influences on city form. Focusing on the features of LA's geologic conditions and civil circumstances, we argued that the relationship between LA's low-density pattern and car dependence is more involved than previously deemed simple causality. The low density should be primarily credited to the spacious requirement of the mining industry, frequent earthquakes and multiethnic population of the city. Oil reserves in LA fueled its economic boom and fast urbanization that coincided with the start of mass production of cheap cars, and cars became medium-priced consumables for average families. Politicians preference for short construction-peried projects enabled fast establishment of LA's highway infrastructure. The popularity of car use in return faciliatated further development of the low-density pattern of the city. The low-density urban form and car dependence created environmental and social problems for LA. Looking at P. R. China's motorization and urban development, we found that the trajectory of Beijing's motorization between 1978 and 2003 coincides with that of the U.S. in the 1910s and 1920s. Lessons from LA's urban and transportation development should be suggestive to China's urban and transportation planning.

  13. Fragmented Flows: Water Supply in Los Angeles County

    Science.gov (United States)

    Pincetl, Stephanie; Porse, Erik; Cheng, Deborah

    2016-08-01

    In the Los Angeles metropolitan region, nearly 100 public and private entities are formally involved in the management and distribution of potable water—a legacy rooted in fragmented urban growth in the area and late 19th century convictions about local control of services. Yet, while policy debates focus on new forms of infrastructure, restructured pricing mechanisms, and other technical fixes, the complex institutional architecture of the present system has received little attention. In this paper, we trace the development of this system, describe its interconnections and disjunctures, and demonstrate the invisibility of water infrastructure in LA in multiple ways—through mapping, statistical analysis, and historical texts. Perverse blessings of past water abundance led to a complex, but less than resilient, system with users accustomed to cheap, easily accessible water. We describe the lack of transparency and accountability in the current system, as well as its shortcomings in building needed new infrastructure and instituting new water rate structures. Adapting to increasing water scarcity and likely droughts must include addressing the architecture of water management.

    LIANG Shiqiang; XU Jingzhong

    2004-01-01

    In order to clarify whether static electricity can impose a control on physical adsorption of polar adsorbates, MD simulations were carried out to study the adsorption/desorption behavior of methanol in the nanopores of electrified activated carbon fiber (ACF). Some special phenomena were observed from the MD simulations for methanol adsorption in a mesopore of electrified ACF. For example it takes a shorter time for the adsorbates to reach the adsorption sites on the mesopore wall, the liquid-like methanol is highly condensed, the methanol molecules have a unique distribution of space orientation, and the total energy of equilibrium state dropped a lot. These phenomena indicate the static electricity reinforced the interaction between the polar methanol and the electrified ACF, so that the intensity, stability and regularity of adsorption were increased, and thus we predict that the adsorption capacity will be increased and the adsorption process will be accelerated. When adsorption equilibrium was reached at room temperature, eliminated the electric charges and heated the system, the desorption tendency was evidently observed from our simulations at 60℃ or so.

    Primary (TCP) collimators of the betatron cleaning insertion determine the betatron cut of the LHC beam. During the 2016 they were set at 5.5 nominal beam sigmas at 6.5 TeV (i.e. by using a normalized emittance " = 3:5 m is used). Reducing their settings is a possible way to push the at the LHC, which depends on the collimation hierarchy. This study aims at understanding possible limitations of operating the LHC with tighter settings of the primary collimators. This is a crucial input to the choice of operational conguration in terms of at the LHC as well as at the HL-LHC. This study follows a successful MD done in block 3 to understand limitations from TCP impedance [1]. The outcome of this MD can also have an impact for the design of the FCC collimation system, which is currently based on the present TCP gaps. Studies of beam stability as a function of octupole current, transverse feedback gain (ADT) and transverse separation at the IPs were also carried out.

    Ferritic/martensitic steels considered as candidate first-wall materials for fusion reactors experience significant radiation hardening at temperatures below ˜400 °C. A number of experimental studies in ferritic alloys, performed at higher temperatures, have shown the existence of large interstitial loops with Burgers vector {1}/{2} and in the bulk, which may provide a significant contribution to the hardening caused during irradiation at lower temperatures. Hardening arises from a high number density of loops, voids and small precipitates, which pin system dislocations, impeding their free glide. In this work, we review the nature of the different interstitial dislocation loops observed in α-Fe and ferritic materials, assess the effect of substitutional impurities on migrating {1}/{2} clusters, and apply atomistic modeling to investigate the mechanisms of formation and growth of loops from smaller cascade-produced {1}/{2} clusters. The proposed mechanism reconciles experimental observations with continuum elasticity theory and recent MD modeling of defect production in displacement cascades. In addition, the interaction of screw dislocations, known to control the low-temperature plastic response of b.c.c. materials to external stress, with dislocation loops is investigated with MD, where the main physical mechanisms are identified, cutting angles estimated and a first-order estimation of the induced hardening is provided.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

The love of Tess with Angle Clare and Alec d' Urbervil e is also the tragedy in Tess of the D' urbervil es of Thomas Hardy who is a cross-century literary giants. He is one of the most famous writers in the Victorian era, and is known as“Shakespeare in the English novels”. Tess of the D' urbervil es is one of his famous novels and it is the combination of Hardy’ pessimism and fatalism. Of course, Tess’ tragic fate has thousands of thousands contact with Alec and Angle Clare. In Hardy’ writing, Tess is a pure, beautiful, kind-hearted, and nearly a perfect peasant girl and a series of happenings make the girl go to death. Tess lives in the capital society. The self-supporting peasants are displaced and impoverished, and are forced to work under capitalist exploitation. Her parents’ vanity makes her go to work in Alec’s farm where she loses the most precious chastity of women. While when she begins to choose the new life and struggles to get rid of the moral bound, her husband Angel Clare leaves her after he knows the impurity past of Tess. The two men in Tess’ life help to create the tragedy. Tess ruins herself by a extreme way. This thesis is trying to make comments on the influences of the two men--Alec and Angle to Tess’ tragedy. If the ravages of body by Alec is the beginning of the tragedy, then the mental torture ultimately destroyed Tess and make her to despair and destruction.

    Human erythrocytes that are homozygous for the Duarte enzyme variant of galactosemia (D/D) have a characteristic isoform on isoelectric focusing and 50% reduction in galactose-1-phosphate uridyltransferase (GALT) enzyme activity. The Duarte biochemical phenotype has a molecular genotype of N314D/N314D. The characteristic Duarte isoform is also associated with a variant called the {open_quotes}Los Angeles (LA) phenotype,{close_quotes} which has increased GALT enzyme activity. We evaluated GALT enzyme activity and screened the GALT genes of 145 patients with one or more N314D-containing alleles. We found seven with the LA biochemical phenotype, and all had a 1721C{r_arrow}T transition in exon 7 in cis with the N314D missense mutation. The 1721C{r_arrow}T transition is a neutral polymorphism for leucine at amino acid 218 (L218L). In pedigree analyses, this 1721C{r_arrow}T transition segregated with the LA phenotype of increased GALT activity in three different biochemical phenotypes (LA/N, LA/G, and LA/D). To determine the mechanism for increased activity of the LA variant, we compared GALT mRNA, protein abundance, and enzyme thermal stability in lymphoblast cell lines of D and LA phenotypes with comparable genotypes. GALT protein abundance was increased in LA compared to D alleles, but mRNA was similar among all genotypes. We conclude that the codon change N314D in cis with the base-pair transition 1721C{r_arrow}T produces the LA variant of galactosemia and that this nucleotide change increases GALT activity by increasing GALT protein abundance without increasing transcription or decreasing thermal lability. A favorable codon bias for the mutated codon with consequently increased translation rates is postulated as the mechanism. 23 refs., 3 figs., 4 tabs.

    Strains of Lactobacillus bulgaricus and Angel Yeast were combined to ferment raw pork and make pork jerky. After fermentation, the jerky was dried and then tested for sensory evaluation, pH and free amino acid content. The results showed that the optimal conditions for fermentation using L. bulgaricus and Angel Yeast were: a pH of 6.5, a 1:1 (v/v) ratio of L. bulgaricus to Angel Yeast, a fermentation time of 42 h and temperature of 25 °C. The results showed that the pork jerky fermented with the combined strains was not very sour which was close to the pH of 7.0 and had a higher free amino acid content which was more than 68.3 mg/100 g compared with the pork jerky fermented by either L. bulgaricus or Angel Yeast alone. Overall, the results demonstrate that fermentation of raw pork with combined strains of L. bulgaricus and Angel Yeast improves the quality and flavor of pork jerky.

  7. Interseismic deformation associated with three-dimensional faults in the greater Los Angeles region, California

    Marshall, Scott T.; Cooke, Michele L.; Owen, Susan E.

    2009-12-01

    Existing interseismic models are not well-suited to simulate deformation within the network of finite, intersecting, nonplanar faults observed in the greater Los Angeles region. Instead of applying fault slip rates to a model a priori, we allow three-dimensional fault surfaces to interact and accumulate mechanically viable slip distributions and then use the deep nonseismogenic portion of slip to calculate interseismic deformation. We apply this approach to the Los Angeles region and find that the geologic timescale model results match well geologic slip rate data and the interseismic timescale model results match well the heterogeneous GPS velocity pattern in the Los Angeles region. Model results suggest that localized geodetic convergence in the San Gabriel basin can be achieved with slip on multiple active fault surfaces in the Los Angeles region including relatively fast slip on the Sierra Madre fault and slow slip on the Puente Hills thrusts, in agreement with geologic data. The ability of the three-dimensional model to reproduce well both geologic slip rates and interseismic geodetic velocity patterns suggests that current day contraction rates in the greater Los Angeles region are compatible with long-term geologic deformation rates and disputes suggestions of significant temporal variations in fault slip rates inferred from existing investigations.

  8. Luminosity Anti-leveling with Crossing Angle (MD 1669)

    Gorzawski, Arkadiusz; Ponce, Laurette; Salvachua Ferrando, Belen Maria; Wenninger, Jorg; CERN. Geneva. ATS Department

    2016-01-01

    A significant fraction of the LHC luminosity ($\\sim$30\\% in 2016) is lost due to the presence (and necessity) of the crossing angles at the IPs. At the LHC the crossing angle is typically set to a value that provides sufficient separation of the beams at the start of fills for the peak bunch intensities. As the bunch intensity decays during a fill, it is possible to reduce the crossing angle and recover some luminosity. A smooth crossing angle reduction procedure must be developed to take advantage of this option during stable beam operation. During this MD a smooth procedure for luminosity leveling with crossing angle was tested. It was demonstrated that the orbit was well controlled, beam losses were low and the offset leveled experiments ALICE and LHCb were not affected by crossing angle leveling in ATLAS and CMS.

    This note describes the results obtained during the second so-called ATS MD where the record of Beta* was reached at IP1 and IP5 with a “pre-squeezed” Beta* of 1.2 m, while perfectly controlling the chromatic aberrations induced (non-linear chromaticity, off-momentum Beta-beating). Then, the ATLAS insertion was squeezed further down to the target of the former LHC Upgrade Project (Phase I), that is to Beta* = 30 cm, using the Achromatic Telescopic Squeezing techniques. In view of this major achievement, the bar is fixed even higher for the next ATS MD’s, with an ultimate Beta* targeted to 10 cm for the two high-luminosity insertions ATLAS and CMS.

  10. Emily Dickinson's ophthalmic consultation with Henry Willard Williams, MD.

    2012-12-01

    Emily Dickinson is one of America's premier poets of the 19th century. Henry Willard Williams, MD, was one of the very first physicians to limit his practice to ophthalmology and was the established leader in his field in Boston, Massachusetts. They met during the time of the Civil War, when Emily consulted him about her ophthalmic disorder. No records of the diagnosis survive. Photophobia, aching eyes, and a restriction in her ability to work up close were her main symptoms. Iritis, exotropia, or psychiatric problems are the most frequent diagnoses offered to explain her difficulties. Rather than attempt a definitive conclusion, this article will offer an additional possibility that Dr Williams likely considered (ie, hysterical hyperaesthesia of the retina). This was a common diagnosis at that time, although it has currently faded from use.

    Full Text Available Success in academic medicine requires scientific and clinical aptitude and the ability to lead a team effectively. Although combined MD/PhD training programs invest considerably in the former, they often do not provide structured educational opportunities in leadership, especially as applied to investigative medicine. To fill a critical knowledge gap in physician-scientist training, the Vanderbilt Medical Scientist Training Program (MSTP developed a biennial two-day workshop in investigative leadership. MSTP students worked in partnership with content experts to develop a case-based curriculum and deliver the material. In its initial three offerings in 2006, 2008, and 2010, the workshop was judged by MSTP student attendees to be highly effective. The Vanderbilt MSTP Leadership Workshop offers a blueprint for collaborative student-faculty interactions in curriculum design and a new educational modality for physician-scientist training.

    Leonard F. Peltier, MD, PhD, was an orthopaedic surgeon, academician, administrator, laboratory investigator, historian, and mentor. His career spanned nearly six decades, beginning with graduate education at the University of Minnesota (UM) under the auspices of Owen H. Wangensteen, MD, PhD. In addition to obtaining a PhD in physiology in the UM Graduate School, he completed general and orthopaedic surgery residencies and attained board certification in each specialty. He served in the US Army Occupation Force Medical Corps in Germany just after World War II. In 1957, at 37 years old, he assumed the chairmanship of the orthopaedic training program at the University of Kansas. In 1971, he couldn't resist the opportunity to become one of the founding members of the "start-up" University of Arizona College of Medicine, accepting an appointment as chair of the new orthopaedic training program, where he remained until his retirement in 1990. He took clinical problems to the laboratory, and made important scientific contributions, particularly in the area of fat embolism and in using calcium sulfate (plaster of Paris) to fill bone defects. He served on governing boards of national professional organizations and presided over the American Association for the Surgery of Trauma from 1980-1981. Throughout his career, he was fascinated by, and published extensively in, the history of medicine arena. Known fondly as "the professor" to many of his residents and colleagues, he had a pragmatic, honest, upbeat, and often humorous approach to life's challenges, valuing personal integrity above other virtues. He explored various eclectic interests far beyond his professional contributions while maintaining his family as a central priority. With his exemplary productivity and interests in the surgical and laboratory sciences, history of medicine, appreciation of fine arts, and perceptive and effective interactions with family, friends, patients, and colleagues, the memory of Leonard

    We previously identified a novel alternatively spliced isoform of human myeloid differentiation protein-2 (MD-2s) that competitively inhibits binding of MD-2 to TLR4 in vitro. Here we investigated the protective role of MD-2s in LPS-induced acute lung injury by delivering intracheally (i.t.) an adenovirus construct that expressed MD-2s (Ad-MD-2s). After adenovirus-mediated gene transfer, MD-2s was strongly expressed in lung epithelial cells and readily detected in bronchoalveolar lavage fluid (BALF). Compared to Ad-EV control mice, Ad-MD-2s delivery resulted in significantly less LPS-induced inflammation in the lungs, including less protein leakage, cell recruitment, and expression of proinflammatory cytokines and chemokines, such as IL-6, KC, and MIP-2. BALF from Ad-MD-2s mice transferred into lungs of naive mice before i.t. LPS challenge diminished pro-inflammatory cytokine levels. As house dust mite (HDM) sensitization is dependent on TLR4 and HDM Der p 2, a structural homolog of MD-2, we also investigated the effect of MD-2s on house dust mite (HDM)-induced allergic airway inflammation. Ad-MD-2s given before HDM sensitization significantly inhibited subsequent allergic airway inflammation after HDM challenge, including reductions in eosinophils, goblet cell hyperplasia, and IL-5 levels. Our study indicates that the alternatively spliced short isoform of human MD-2 could be a potential therapeutic candidate to treat human diseases induced or exacerbated by TLR4 signaling, such as Gram-negative bacterial endotoxin-induced lung injury and house dust mite-triggered allergic lung inflammation.

    The Los Angeles County University of Southern California Medical Center will open soon, replacing the county's current 74-year-old facility with a modern, although smaller, facility. Los Angeles County has provided hospital care to the indigent since 1858, during which time, the operation of public hospitals has shifted from a state-mandated welfare responsibility to a preeminent part of the county's public health mission. As this shift occurred, the financing of Los Angeles County hospitals changed from primarily county support to state and federal government sources, particularly Medicaid. The success of the new hospital will depend on whether government leaders at all levels provide the reforms needed to help the county and its partners stabilize its funding base.

    2008-04-01

    Predicting Los Angeles abrasion loss of aggregate material from some simpler tests will be useful for especially preliminary studies. For this reason, to investigate the possibility of predicting the Los Angeles abrasion loss from the crushability index, Los Angeles abrasion, crushability, density and porosity tests were performed on 11 different rock types collected from different areas of Turkey. The results of the tests were analysed using simple and multiple regression analyses. Generally significant correlations were obtained from both simple and multiple regression analyses. The correlation coefficients and estimation capabilities of the two multiple regression equations are slightly higher than that of the simple regression equation. It was concluded that the simple regression equation is practical and reliable enough for estimation purposes. However, the two multiple regression equations can be used for a more accurate estimation.

    1994-08-01

    The effect of Medicare on two public hospitals in Los Angeles County was analyzed by examining the percentage of patients 65 years of age and older among all discharges from 1958 through 1971. At Harbor General Hospital, discharges of elderly patients had dropped from 21.7% to 7.9% by late 1966; at Los Angeles County General Hospital, discharges decreased from 15.3% to 10.7% between 1966 and 1967. Monitoring public hospitals' demographic changes after enacting a national health plan may provide information on patients' and providers' acceptance of insurance and on resources needed by public hospitals to care for those left without coverage.

    Transport of aerosol particles is known to affect air quality and is largely dependent on the characteristic topography of the surrounding region. To characterize this transport, aerosol number distributions were collected with an Ultra-High Sensitivity Aerosol Spectrometer (UHSAS, DMT) during the 2015 NASA Student Airborne Research Program (SARP) in and around the Los Angeles Basin in Southern California. Increases in particle number concentration and size were observed over mountainous terrain north of Los Angeles County. Chemical analysis and meteorological lagrangian trajectories suggest orographic lifting processes, known as the "chimney effect". Implications for spatial transport and distribution will be discussed.

    通过研究不同的差分分析对MD5算法的攻击后发现,差分分析攻击之所以可以成功,是因为在MD5算法中改变了明文中一些特定位,而这些特定位的改变在许多轮中最多只影响链接变量的几个位,并且这些小的差分能在随后的多轮操作中得到纠正,从而产生了碰撞.这就说明原MD5算法的雪崩效应不能阻止差分分析的攻击,而为了提高MD5算法的安全性,必须提高其雪崩效应的敏感性.分析结果表明,用动态明文变化函数对MD5算法进行修改,能使其产生更敏感的雪崩效应,以此来有效防止差分分析攻击,提高MD5算法的安全性.

    2017-01-01

    In case of an asynchronous beam dump with a fully filled LHC machine it is expected that all standard ionisation chamber Beam Loss Monitors (IC BLM) around the LHC dumping region in IP6 will be saturated. Diamond Beam Loss Monitors (dBLM) were therefore installed next to the movable dump protection absorber (TCDQ) downstream of the extraction kickers. These detectors allow resolving losses at a nanosecond timescale and with an dynamic range of several orders of magnitude; thus, allowing to know the number of nominal bunches impacting the TCDQ. After a first series of calibrations using asynchronous beam dump tests, an experiment was conducted during MD#1182 to demonstrate the possibility of resolving a nominal bunch hitting the TCDQ. The impact parameter of the bunches on the TCDQ was first scanned using probe bunches with lower intensity then tests were done with nominal bunches (1.1e11 p/bunch) at injection energy. High energy calibration of the losses was also attempted unsuccessfully. Due to different beh...

The system was developed by the Management of Electrical equipment of the Instituto de Investigaciones Electricas (IIE) and implemented in the six units of generation of the Manzanillo Thermoelectric Unit. The present article includes a description of the main components and functions. The world-wide tendency in monitoring systems of the fault statistics, were key elements in defining the variable to be monitored: Partial discharges (PD), Shaft current (SC), Neutral current (NC), Tangential Magnetic (TM) flux, Voltages and currents of line (as reference to the operation point). The main processes of deterioration that are intended to be observed with each one of these variables are described with greater thoroughness in the article Sistema AnGel: Aspectos teorico-practicos para el diagnostico de generadores en operacion (AnGel System: Theoretical-practical aspects for the diagnosis of generators in operation), contained in the section of Research Activities in this same issue of the IIE bulletin.

  15. H5MD: a structured, efficient, and portable file format for molecular data

    CERN Document Server

    de Buyl, Pierre; Höfling, Felix

    2013-01-01

    We propose a new open file format named "H5MD" for storing molecular simulation data such as trajectories of particle positions and velocities as well as thermodynamic observables that are tracked during the course of the simulation. H5MD files are HDF5 (Hierarchical Data Format) files with a specific hierarchy and naming scheme. Thus, H5MD inherits many benefits of HDF5, e.g., structured layout of multi-dimensional data sets, data compression, fast and parallel I/O, and portability across many programming languages and hardware platforms. H5MD files are self-contained, and foster the reproducibility of scientific data and the interchange of data between researchers using different simulation programs and analysis software. In addition, the H5MD specification can serve for other kinds of data (e.g. experimental data) and is extensible to supplemental data without breaking the compliance of the file to the specification.

  18. Comparison of ozone exposure characteristics in forested regions near Mexico City and Los Angeles

    Science.gov (United States)

    Miller, Paul R.; de Lourdes de Bauer, María; Quevedo Nolasco, Abel; Hernández Tejeda, Tomás

    This comparison of forest exposure to ozone in the vicinity of México City and Los Angeles provides preliminary evidence of the seasonal differences in ozone concentrations. Summer concentrations near México City are not as high as those near Los Angeles because most of the precipitation and associated cloudiness occurs near México City during the months of June through September. Winter concentrations remain nearly as high as summer concentrations at México City, because in winter skies are clearer and incident sunlight remains high. Latitudinal influences on solar zenith angle and the higher altitude of the México City region both contribute to a higher actinic flux than in the Los Angeles region. The primary difference in forest exposure is that there is very little respite from adverse ozone concentrations during the entire year in the México City region. Also, the rainy summer season would likely diminish water stress and result in greater ozone uptake at the Desierto de los Leones compared to dry summer conditions in California. The closer proximity of the Desierto de los Leones monitoring site to the urban area also contributes to high winter exposures. There is some respite from exposure during the winter in the San Bernardino mountain region; however, summer concentrations are higher than near México City. The greater transport distance from the Los Angeles source region also contributes to lower winter exposures.

  19. Evolving Groundwater Rights and Management in Metropolitan Los Angeles: Implications for Water Supply and Stormwater

    Science.gov (United States)

    Porse, E.; Pincetl, S.; Glickfeld, M.

    2015-12-01

    Groundwater supports many aspects of human life. In cities, groundwater can provide a cost-effective source of water for drinking and industrial uses, while groundwater basins provide storage. The role of groundwater in a city's water supply tends to change over time. In the Los Angeles metropolitan area, groundwater is critical. Over decades, users in the region's many basins allocated annual pumping rights to groundwater among users through adjudications. These rights were determined through collective processes over decades, which contributed to the complex array of public and private organizations involved in water management. The rights also continue to evolve. We analyzed changes in the distribution of groundwater rights over time for adjudicated basins in Southern Los Angeles County. Results indicate that groundwater rights are increasingly: 1) controlled or regulated by public institutions and municipalities, and 2) consolidated among larger users. Yet, both the percentage of total supplies provided by groundwater, as well as the distribution of groundwater rights, varies widely among cities and communities throughout Los Angeles. As metropolitan Los Angeles faces reduced water imports and emphasizes local water reliance, access to pumping rights and storage capacity in groundwater basins will become even more vital. We discuss implications of our results for future urban water management.

  1. Md1 and Rp105 regulate innate immunity and viral resistance in zebrafish.

    2015-06-01

    TLR4 was the first TLR family member identified in mammals and is responsible for the activation of the immune response by bacterial LPS. Later, MD1 and RP105 were shown to form complexes that directly interact with the MD2-TLR4 complex, acting as physiological negative regulators of LPS signaling. Despite the general conservation of various TLR families from fish to mammals, several differences can be appreciated, such as the high tolerance of fish to LPS, the absence of the crucial accessory molecules Md2 and Cd14 for Tlr4 signaling in fish, the absence of Tlr4 in some fish species, and the confirmation that LPS does not signal through Tlr4 in zebrafish. The present study has identified the Rp105 and Md1 homologs in zebrafish, confirming (i) Rp105 and Tlr4 evolved from a common ancestor before the divergence between fish and tetrapods and (ii) the presence of Md1 in teleost fish and the lack of Md2, suggesting that the divergence of these accessory molecules occurred in the tetrapod lineage. Biochemical and functional studies indicate that Md1 binds both Rp105 and Tlr4 in zebrafish. Genetic inhibition of zebrafish Md1 and Rp105 reveals that Md1 or Rp105 deficiency impairs the expression of genes encoding pro-inflammatory and antiviral molecules, leading to increased susceptibility to viral infection. These results shed light on the evolutionary history of Md1 and Rp105 and uncover a previously unappreciated function of these molecules in the regulation of innate immunity.

  2. Electroporation of archaeal lipid membranes using MD simulations.

    Molecular dynamics (MD) simulations were used to investigate the electroporation of archaeal lipid bilayers when subjected to high transmembrane voltages induced by a charge imbalance, mimicking therefore millisecond electric pulse experiments. The structural characteristics of the bilayer, a 9:91 mol% 2,3-di-O-sesterterpanyl-sn-glicerol-1-phospho-myo-inositol (AI) and 2,3-di-O-sesterterpanyl-sn-glicerol-1-phospho-1'(2'-O-α-D-glucosyl)-myo-inositol (AGI) were compared to small angle X-ray scattering data. A rather good agreement of the electron density profiles at temperatures of 298 and 343 K was found assessing therefore the validity of the protocols and force fields used in simulations. Compared to dipalmitoyl-phosphatidylcholine (DPPC), the electroporation threshold for the bilayer was found to increase from ~2 V to 4.3 V at 323 K, and to 5.2 V at 298 K. Comparing the electroporation thresholds of the archaeal lipids to those of simple diphytanoyl-phosphatidylcholine (DPhPC) bilayers (2.5 V at 323 K) allowed one to trace back the stability of the membranes to the structure of their lipid head groups. Addition of DPPC in amounts of 50 mol% to the archaeal lipid bilayers decreases their stability and lowers the electroporation thresholds to 3.8 V and 4.1 V at respectively 323 and 298 K. The present study therefore shows how membrane compositions can be selected to cover a wide range of responses to electric stimuli. This provides new routes for the design of liposomes that can be efficiently used as drug delivery carriers, as the selection of their composition allows one to tune in their electroporation threshold for subsequent release of their load.

    Full Text Available Nutrient deficiencies restrict apple (Malus sp. tree growth and productivity in Northwest China. The process of autophagy, a conserved degradation pathway in eukaryotic cells, has important roles in nutrient-recycling and helps improve plant performance during periods of nutrient-starvation. Little is known about the functioning of autophagy-related genes (ATGs in apple. In this study, one of the ATG8 gene family members MdATG8i was isolated from M. domestica. MdATG8i has conserved putative tubulin binding sites and ATG7 interaction domains. A 1865-bp promoter region cloned from apple genome DNA was predicated to have cis-regulatory elements responsive to light, environmental stresses and hormones. MdATG8i transcriptions were induced in response to leaf senescence, nitrogen depletion, and oxidative stress. At cellular level, MdATG8i protein was expressed in the nucleus and cytoplasm of onion epidermal cells. Yeast two-hybrid tests showed that MdATG8i could interact with MdATG7a and MdATG7b. In Arabidopsis, its heterologous expression was associated with enhanced vegetative growth, leaf senescence, and tolerance to nitrogen- and carbon-starvation. MdATG8i-overexpressing ‘Orin’ apple callus lines also displayed improved tolerance to nutrient-limited conditions. Our results demonstrate that MdATG8i protein could function in autophagy in a conserved way, as a positive regulator in the response to nutrient-starvation.

  6. Osmotically and thermally isolated forward osmosis-membrane distillation (fo-md) integrated module for water treatment applications

    2016-09-01

    An integrated forward osmosis-membrane distillation (FO-MD) module and systems and methods incorporating the module is disclosed providing higher efficiencies and using less energy. The FO-MD module is osmotically and thermally isolated. The isolation can prevent mixing of FO draw solution/FO permeate and MD feed, and minimize dilution of FO draw solution and cooling of MD feed. The module provides MD feed solution and FO draw solution streams that flow in the same module but are separated by an isolation barrier. The osmotically and thermally isolated FO-MD integrated module, systems and methods offer higher driving forces of both FO and MD processes, higher recovery, and wider application than previously proposed hybrid FO- MD systems.

    A native isolate Lactobacillus farciminis MD isolated from fermenting mushroom exhibited a high degree of sensitivity to the majority of the bacteriocins produced by strains of lactobacilli, leuconostoc and pediococci. Also, the efficacy of Lact. farciminis MD as a sensitive strain for antibiotic assay was established against different antibiotics including ampicillin, cefazoline, chloramphenicol and nitrofurantoin at concentrations of 30 microg each, showing an inhibition zone of 30 mm diameter. The high degree of sensitivity towards bacteriocins and antibiotics provide potential for the exploitation of Lact. farciminis MD in establishing very well-defined bacteriocin producers.

    The concept of core competencies in graduate medical education was introduced by the Accreditation Council for Graduate Medical Education of the American Medical Association to semiquantitatively assess the professional performance of students, residents, practitioners, and faculty. Many aspects of the career of J. Marion Sims, MD, are exemplary of those core competencies: MEDICAL KNOWLEDGE: Author of the first American textbook related to gynecology. MEDICAL CARE: Innovator of the Sims' Vaginal Speculum, Sims' Position, Sims' Test, and vesico-/rectovaginal fistulorrhaphy; advocated abdominal exploration for penetrating wounds; performed the first cholecystostomy. PROFESSIONALISM: Served as President of the New York Academy of Medicine, the American Medical Association, and the American Gynecologic Society. INTERPERSONAL RELATIONSHIPS/COMMUNICATION: Cared for the indigent, hearthless, indentured, disenfranchised; served as consulting surgeon to the Empress Eugénie (France), the Duchess of Hamilton (Scotland), the Empress of Austria, and other royalty of the aristocratic Houses of Europe; accorded the National Order of the Legion of Honor. PRACTICE-BASED LEARNING: Introduction of silver wire sutures; adoption of the principles of asepsis/antisepsis; adoption of the principles of general anesthesia. SYSTEMS-BASED PRACTICE: Established the Woman's Hospital, New York City, New York, the predecessor of the Memorial Sloan-Kettering Center for the Treatment of Cancer and Allied Diseases; organized the Anglo-American Ambulance Corps under the patronage of Napoleon III. What led him to a life of clinical and humanitarian service? First, he was determined to succeed. His formal medical/surgical education was perhaps the best available to North Americans during that era. Second, he was courageous in experimentation and innovation, applying new developments in operative technique, asepsis/antisepsis, and general anesthesia. Third, his curiosity was not burdened by rigid

    This report summarizes the progress on the interatomic potential development of triuranium-disilicide (U3Si2) for molecular dynamics (MD) simulations. The development is based on the Tersoff type potentials for single element U and Si. The Si potential is taken from the literature and a Tersoff type U potential is developed in this project. With the primary focus on the U3Si2 phase, some other U-Si systems such as U3Si are also included as a test of the transferability of the potentials for binary U-Si phases. Based on the potentials for unary U and Si, two sets of parameters for the binary U-Si system are developed using the Tersoff mixing rules and the cross-term fitting, respectively. The cross-term potential is found to give better results on the enthalpy of formation, lattice constants and elastic constants than those produced by the Tersoff mixing potential, with the reference data taken from either experiments or density functional theory (DFT) calculations. In particular, the results on the formation enthalpy and lattice constants for the U3Si2 phase and lattice constants for the high temperature U3Si (h-U3Si) phase generated by the cross-term potential agree well with experimental data. Reasonable agreements are also reached on the elastic constants of U3Si2, on the formation enthalpy for the low temperature U3Si (m-U3Si) and h-U3Si phases, and on the lattice constants of m-U3Si phase. All these phases are predicted to be mechanically stable. The unary U potential is tested for three metallic U phases (α, β, γ). The potential is found capable to predict the cohesive energies well against experimental data for all three phases. It matches reasonably with previous experiments on the lattice constants and elastic constants of αU.

    Myeloid differentiation factor 2 (MD-2) is a secreted gp that assembles with TLR4 to form a functional signaling receptor for bacterial LPS. In this study, we have identified a novel alternatively spliced isoform of human MD-2, termed MD-2 short (MD-2s), which lacks the region encoded by exon 2 of the MD-2 gene. Similar to MD-2, MD-2s is glycosylated and secreted. MD-2s also interacted with LPS and TLR4, but failed to mediate LPS-induced NF-kappaB activation and IL-8 production. We show that MD-2s is upregulated upon IFN-gamma, IL-6, and TLR4 stimulation and negatively regulates LPS-mediated TLR4 signaling. Furthermore, MD-2s competitively inhibited binding of MD-2 to TLR4. Our study pinpoints a mechanism that may be used to regulate TLR4 activation at the onset of signaling and identifies MD-2s as a potential therapeutic candidate to treat human diseases characterized by an overly exuberant or chronic immune response to LPS.

    2013-01-01

    The cryptographic hash functions Extended MD4 and RIPEMD are double-branch hash functions,which consist of two parallel branches.Extended MD4 was proposed by Rivest in 1990,and RIPEMD was devised in the framework of the RIPE project (RACE Integrity Primitives Evaluation,1988~1992).On the basis of differential analysis and meet-in-the-middle attack principle,this paper proposes a collision attack on the full Extended MD4 and a pseudo-preimage attack on the full RIPEMD respectively.The collision attack on Extended MD4 holds with a complexity of 237,and a collision instance is presented.The pseudo-preimage attack on RIPEMD holds with a complexity of 2125,4,which optimizes the complexity order for brute-force attack.The results in this study will also be beneficial to the analysis of other double-branch hash functions such as RIPEMD-160.

  4. Sustainable water recovery from oily wastewater via forward osmosis-membrane distillation (FO-MD).

    This study proposed and investigated a hybrid forward osmosis - membrane distillation (FO-MD) system for sustainable water recovery from oily wastewater by employing lab-fabricated FO and MD hollow fiber membranes. Stable oil-in-water emulsions of different concentrations with small droplet sizes (<1 μm) were firstly prepared and applied as the feed solution in the FO process. Fouling was immediately observed in the FO mode and was low on the cellulose triacetate (CTA) - based thin film composite (TFC) membranes. Moreover, slight increment of fouling was observed in the first few hours and the water flux was then stabilized over 24 h. The characterizations of water flux and solute rejection in separate FO and MD processes revealed that a high water flux, good NaCl rejection, impressively high retention of oil droplets and partial permeation of acetic acid could be achieved. Finally, an integrated FO-MD system was developed to treat the oily wastewater containing petroleum, surfactant, NaCl and acetic acid at 60 °C in the batch mode. The water flux in FO undergoes three-stage decline due to fouling and reduction in osmotic driving force, but is quite stable in MD regardless of salt concentration. Oily wastewater with relatively high salinity could be effectively recovered by the FO-MD hybrid system while maintaining large water flux, at least 90% feed water recovery could be readily attained with only trace amounts of oil and salts, and the draw solution was re-generated for the next rounds of FO-MD run. Interestingly, significant amount of acetic acid was also retained in the permeate for further reuse as a chemical additive during the production of crude oil. The work has demonstrated that not only water but also organic additives in the wastewater could be effectively recovered by FO-MD systems for reuse or other utilizations.

  7. Systemic Reform in a Federated System:Los Angeles at the Turn of the Millennium

    Directory of Open Access Journals (Sweden)

    David Menefee-Libey

    2004-10-01

    Full Text Available I synthesize some of the lessons we have learned about systemic school reform in order and derive two explicit hypotheses about when such reforms are likely to be more and less successful. The first hypothesis focuses on program implementation: to achieve success, any systemic reform must overcome challenges at each stage of the policy-making process, from agenda-setting to policy choice to implementation. The second hypothesis focuses on the federated nature of education policymaking in the United States: any successful systemic reform must offer a program that aligns local efforts with state and sometimes federal policy. I derive and test more specific hypotheses related to recent systemic reform efforts in the Los Angeles region—especially the Los Angeles Annenberg Metropolitan Project, or LAAMP—which ran from 1995 through 2001. The case confirms the hypotheses and enables a clearer understanding of systemic school reform.

  8. Remote Sensing of Spatial Distributions of Greenhouse Gases in the Los Angeles Basin

    2010-01-01

    The Los Angeles air basin is a significant anthropogenic source of greenhouse gasses and pollutants including CO2, CH4, N2O, and CO, contributing significantly to regional and global climate change. Recent legislation in California, the California Global Warning Solutions Act (AB32), established a statewide cap for greenhouse gas emissions for 2020 based on 1990 emissions. Verifying the effectiveness of regional greenhouse gas emissions controls requires high-precision, regional-scale measurement methods combined with models that capture the principal anthropogenic and biogenic sources and sinks. We present a novel approach for monitoring the spatial distribution of greenhouse gases in the Los Angeles basin using high resolution remote sensing spectroscopy. We participated in the CalNex 2010 campaign to provide greenhouse gas distributions for comparison between top-down and bottom-up emission estimates.

    2012-12-01

    The Los Angeles urban region emits large amounts of methane (~0.44Tg/year) into the atmosphere. It is currently unclear exactly how much of this is biogenic (landfills, cattle), and how much is from natural gas (natural seeps or fugitive emissions from the natural gas infrastructure). Since natural gas contains ethane, whereas biogenic emissions contain none, simultaneous measurements of ethane and methane offer the possibility of separating the biogenic versus natural gas emissions of methane. We investigate this using total column measurements from a new Total Carbon Column Observing Network (TCCON) remote sensing station in the Los Angeles suburb of Pasadena, which began measurements in July 2012. These measurements will be put into the context of historical remote sensing and in situ measurements described by Wennberg et al., 2012 (doi:10.1021/es301138y).

    2010-01-01

    Full Text Available This article argues that a certain type of Shanghai film of the Republican period, exemplified by 1937’s Street Angel (馬路天使, Malu tianshi, makes use of a specific mode of spatial organization, modelled on the theatre, to represent the urban environment. In the case of Street Angel, and later on in 1964’s Stage Sisters (舞台姐妹, Wutai jiemei, the interaction between performers and audiences characteristic of the Shanghai theatre experience serves as a crucial ground on which to base calls to political action. For a variety of related reasons, both the city of Shanghai and this mode of spatial organization so closely associated with it vanish from the big screen in the 1980s and 1990s, and begin to make a return only at the turn of the new century.

    Results are presented of a mineralogical and petrological examination of a relatively large hibonite-containing inclusion in the Murchison chondrite called the Blue Angel. Mechanisms of formation and modification of hibonite-rich inclusions are investigated. Evidence is found that modifying processes occurred before the inclusion was incorporated into its present location, which indicates a sequence of aqueous and metamorphic alteration followed by disruption and relithification of the protometeoritic material. The mineral chemistry and petrography of the Blue Angel is consistent with a three stage formation history, and extensive alteration of Ca-Al-rich inclusions may have occurred by aqueous alteration and thermal metamorphism followed by explosive mixing processes on a parent body.

  14. Parallel Cascade Selection Molecular Dynamics (PaCS-MD) to generate conformational transition pathway.

    Science.gov (United States)

    Harada, Ryuhei; Kitao, Akio

    2013-07-21

    Parallel Cascade Selection Molecular Dynamics (PaCS-MD) is proposed as a molecular simulation method to generate conformational transition pathway under the condition that a set of "reactant" and "product" structures is known a priori. In PaCS-MD, the cycle of short multiple independent molecular dynamics simulations and selection of the structures close to the product structure for the next cycle are repeated until the simulated structures move sufficiently close to the product. Folding of 10-residue mini-protein chignolin from the extended to native structures and open-close conformational transition of T4 lysozyme were investigated by PaCS-MD. In both cases, tens of cycles of 100-ps MD were sufficient to reach the product structures, indicating the efficient generation of conformational transition pathway in PaCS-MD with a series of conventional MD without additional external biases. Using the snapshots along the pathway as the initial coordinates, free energy landscapes were calculated by the combination with multiple independent umbrella samplings to statistically elucidate the conformational transition pathways.

    With the purpose of reducing the heat in the interior of the Tower of the Angel, building of offices located in avenida Paseo de la Reforma of Mexico City, a renovation was carried out that included the installation of an insulating crystal cover in all the building. Also, it was opted for an environmental system of air-cooling to fulfill the functions of the HVAC (Heating, Ventilation and Air Conditioning), systems. It is possible to indicate that, in addition to the energy saving, the applied technology allowed to transform an old and uncomfortable construction into a construction of worldwide class, able to compete with new works of the city and harmonize with present environmental and aesthetic requirements.

Therefore, we used an epidemiologic case-control study design to examine whether residential proximity to heavy-traffic roadways influenced the occurrence of low birth...

  17. Angels as Mirrors of the Human: The Anthropologies of Rilke and Bonaventure through the Lenses of Hans Urs von Balthasar

    Directory of Open Access Journals (Sweden)

    Yves De Maeseneer

    2016-07-01

    Full Text Available In this article we present a theological-anthropological exploration, interpreting the figure of the angel as a mirror of our human condition. The point of departure is an analysis of Hans Urs von Balthasar’s approach to two major sources of our imagination of the angel: Bonaventure (1221−1274 and Maria Rainer Rilke (1875−1926. A comparison of his accounts of the Franciscan theologian and the Modern poet, respectively, reveals remarkable parallels in discourse, clustered around the tensions between vulnerability and openness, immanence and transcendence, and love and loss. Both Rilke and Bonaventure reject the classical angel figure as a human ideal, as it cannot integrate the paradoxes of human existence. Their alternative visions of what it means to be human, have many terms in common: heart, vulnerability, mortality, openness, abyss, suspension, transparency, receptivity, descent (kenosis, humility, poverty, etc. However, their meaning is different because Rilke does not recognize an absolute transcendence as the source of love and the vis-a-vis of the human. This immanentism leaves him no other option than the vain attempt to exorcize the angel figure altogether, while Bonaventure’s vision preserves the angel as an anthropological mirror, albeit an angel radically transfigured by God’s wounded love.

Leurent's method explores chiefly three properties of MD-4:The absorption properties of boolean function, reversibility of the iterative process and specificity of message expansion. After their pseudo preimage attack a tree-based method is followed to transform pseudo preimage to true preimage.Tree-basod method is replaced with random graph method. The complexity of the attack reduces to 298 from 2102.

    2011-11-01

    The innate non-self response systems of the deciduous tree pest, the forest tent caterpillar, Malacosoma disstria has been documented by us in terms of in vitro and in vivo reactions towards the Gram-positive nonpathogenic bacterium, Bacillus subtilis and Gram-negative pathogenic microbe, Xenorhabdus nematophila and their respective surface antigens, lipopoteichoic acids (LTA) and lipopolysaccharides (LPS). These studies, often conducted in whole and diluted hemolymph, preclude examination of plasma-free cellular (hemocyte) responses. Plasma-free hemocytes as primary cultures are difficult to obtain. The floating cell line Md66 and attached cell line Md108 from M. disstria hemocytes were examined as a model for plasma-free M. disstria hemocyte non-self responses. Herein, it was established that although both lines differed from each other and from the primary hemocyte cultures of M. disstria in growth parameters, cell composition and sizes both cell lines displayed granular cell-like (GL) cells and plasmatocyte-like (PL) cells according to morphological criteria and to some extent antigenic similarities based on labeling with anti-Chrysodeixis includens hemocyte monoclonal antibodies. Hemocyte-specific neuroglian-like protein was detected on cells of both cell lines and in the primary hemocyte cultures albeit with staining patterns differing according to culture and cell types, confluency levels and cell-cell adhesion. Both cell lines bound B. subtilis and X. nematophila, the reaction extent varying with the cell line and its cell types. LPS damaged both cell types in the two cell lines whereas LTA enhanced the adhesion of Md66 GL cells to flask surfaces followed by PL cell adhesion. PL cells of both lines, like the primary cultures, phagocytosed FITC-labeled B. subtilis; only Md108 GL cells phagocytosed B. subtilis. In either case phagocytosis was always less in frequency and intensity than the primary cultures. Proteins released from the cell lines differed in

  20. The Walking Renaissance: A Longitudinal Analysis of Walking Travel in the Greater Los Angeles Area, USA

    Directory of Open Access Journals (Sweden)

    Kenneth Joh

    2015-07-01

    Full Text Available Promoting walking travel is considered important for reducing automobile use and improving public health. Recent U.S. transportation policy has incentivized investments in alternative, more sustainable transportation modes such as walking, bicycling and transit in auto-oriented cities such as Los Angeles. Although many past studies have analyzed changes in walking travel across the U.S., there is little clarity on the drivers of change. We address this gap by conducting a longitudinal analysis of walking travel in the greater Los Angeles area from 2001 to 2009. We use travel diary and household data from regional and national surveys to analyze changes in walking trip shares and rates across our study area. Results show that walking has significantly increased across most of Los Angeles, and that increases in walking trips generally correspond with increases in population, employment, and transit service densities. Estimates from fixed-effects regression analysis generally suggest a positive association between population density and walking, and that higher increases in transit stop density are correlated with increased walking trips to and from transit stops. These findings illustrate how regional planning efforts to pursue a coordinated land use-transit planning strategy can help promote walking in auto-oriented or vehicle adopting cities.

  1. The undergraduate physics tutorial program at CSU Los Angeles assessment of utility and areas of interest

    Science.gov (United States)

    Avetyan, Smbat

    The Physics Education Research (PER) group at the University of Washington have researched traditional teaching methods and found that students in introductory physics are lacking a conceptual understanding of the physics material. The solution they put forth is an interactive tutorial program designed to meet the lack of conceptual understanding. Since the tutorial programs inception at CSU Los Angeles in Fall 2006 no evaluation has been successfully undertaken therefore the effect of the tutorial program in the physics 200 series is deeply obscure to the department. The research has shed light on the tutorial program and brought into context its effectiveness on the overall physics 200 series courses at CSU Los Angeles. The researcher has addressed the following research questions, what overall effect does the tutorial program have on the Physics 200 series curriculum? What is the size and significance of gains attributable to the undergraduate calculus based Physics 200 series tutorial program at CSU Los Angeles? What can we learn from gains about individual weekly lessons from the Physics 200 series tutorial courses? What is the correlation of tutorial gains with student final course grades? Are the gains from the tutorial program different for genders? Is there a difference in gains based on the different students' colleges?

  2. The Gaze of the Soul and of the Angel in the Renaissance Philosophy of Marsilio Ficino

    Directory of Open Access Journals (Sweden)

    Marko Uršič

    2015-04-01

    Full Text Available The Renaissance rediscovered the soul as the focus of the universe. Marsilio Ficino calls the soul the “bond of the world” (copula mundi, because it connects the earth and the heaven, immanence and transcendence, time and eternity. On the other hand, the centre of the world becomes more and more relative during the Renaissance period, and individual souls live more and more in their particular times and spaces. In Renaissance paintings, a soul's point of view is determined by perspective, as developed by Masaccio, Fra Angelico, Piero della Francesca et al., and the very position of the eye also features as a “symbolic form” (Erwin Panofsky. However, above each individual and “mobile” soul there are the wings of the “motionless” angel: super animam mobilem est immobilis angelus, as Ficino says in his renaissance Christianity, in reviewing the Platonic-Gnostic myth of the omnipresent angelic gaze. In the archetype of the angel Ficino perceives a metaphor for the all-knowing Intellect, towards which the human soul ascends. Following the iconology of Ernst Gombrich, this paper also takes notice of the influence of Ficino's philosophy on Botticelli's paintings.

  3. Alcohol outlet density and alcohol consumption in Los Angeles county and southern Louisiana

    Directory of Open Access Journals (Sweden)

    Matthias Schonlau

    2008-11-01

    Full Text Available The objective of this study was to assess the relationship between alcohol availability, as measured by the density of off-premise alcohol outlets, and alcohol consumption in Los Angeles county and southern Louisiana, USA. Consumption information was collected through a telephone survey of 2,881 households in Los Angeles county and pre-Katrina southern Louisiana, nested within 220 census tracts. Respondents’ addresses were geo-coded and both neighbourhood (census tracts and buffers of varying sizes and individual (network distance to the closest alcohol outlet estimates of off-sale alcohol outlet density were computed. Alcohol outlet density was not associated with the percentage of people who were drinkers in either site. Alcohol outlet density was associated with the quantity of consumption among drinkers in Louisiana but not in Los Angeles. Outlet density within a one-mile buffer of the respondent’s home was more strongly associated with alcohol consumption than outlet density in the respondent’s census tract. The conclusion is that the relationship between neighbourhood alcohol outlet density and alcohol consumption is complex and may vary due to differences in neighbourhood design and travel patterns.

    Full Text Available Obiettivo del contributo è quello di proporre alcuni spunti di riflessione sul caso della città di celluloide più nota al mondo: Los Angeles. Più in particolare s’intende analizzare la stretta relazione che intercorre tra l’attrattività turistica della metropoli e l’industria cinematografica.  Come ben noto, Los Angeles continua da quasi un secolo a suggestionare l’immaginario collettivo in quanto mecca del cinema e patria di Hollywood, l’industria che ha creato il sogno americano. Tuttavia LA, oggi, è anche una delle prime dieci città mondiali. Rappresenta l’esempio di come l’industria creativa (e il cinema è creatività per definizione sia riuscita a realizzare un sistema economico e d’innovazione tecnologica che funziona come polo di attrazione sia per tutti coloro che intendono sviluppare nuove attività, non possibili in altre parti del mondo, sia per visitatori e turisti attirati da un insieme di fattori emozionali legati alla notorietà dei luoghi del sistema cinematografico e dello spettacolo. Sulla base dell’analisi della letteratura e facendo seguito a esperienze di studio sul campo, il contributo vuole evidenziare la stretta connessione costruita nel corso di più di un secolo tra Hollywood, il luogo, e Hollywood, l’industria, per dimostrare come il luogo di produzione rappresenti una componente unica del prodotto finale, un’autenticazione di qualità soggettive e simboliche in grado di amplificare il valore economico intrinseco e di provocare un’attrazione crescente di attività e persone verso l’area metropolitana di Los Angeles.   This paper discusses Los Angeles as the best-known celluloid city in the world, and focuses particularly on the close relationship between its attractiveness for tourists and the film industry. For almost a century Los Angeles has exerted influence over the collective imagination as the mecca of cinema and home of Hollywood, the industry that created the American dream

    Matrine (MT), the effective component of Sophora flavescens Ait, has been shown to have anti-inflammation, immune-suppressive, anti-tumor, and anti-hepatic fibrosis activities. However, the pharmacological effects of MT still need to be strengthened due to its relatively low efficacy and short half-life. In the present study, we report a more effective thio derivative of MT, MD-1, and its inhibitory effects on the activation of hepatic stellate cells (HSCs) in both cell culture and animal models. Cytological experiments showed that MD-1 can inhibit the proliferation of HSC-T6 cells with a half-maximal inhibitory concentration (IC50) of 62 μmol/L. In addition, MD-1 more strongly inhibits the migration of HSC-T6 cells compared to MT and can more effectively induce G0/G1 arrest and apoptosis. Investigating the biological mechanisms underlying anti-hepatic fibrosis in the presence of MD-1, we found that MD-1 can bind the epidermal growth factor receptor (EGFR) on the surface of HSC-T6 cells, which can further inhibit the phosphorylation of EGFR and its downstream protein kinase B (Akt), resulting in decreased expression of cyclin D1 and eventual inhibition of the activation of HSC-T6 cells. Furthermore, in rats with dimethylnitrosamine (DMN)-induced hepatic fibrosis, MD-1 slowed the development and progression of hepatic fibrosis, protecting hepatic parenchymal cells and improving hepatic functions. Therefore, MD-1 is a potential drug for anti-hepatic fibrosis.

    Molecular Dynamics (MD) simulations is a computational method that employs Newton's laws to evaluate the motions of water, ions, small molecules, and macromolecules or more complex systems, for example, whole viruses, to reproduce the behavior of the biological environment, including water molecules and lipid membranes. Specifically, structural motions, such as those that are dependent of the temperature and solute/ solvent are very important to study the recognition pattern of ligandprotein or protein-protein complexes, in that sense, MD simulations are very useful because these motions can be modeled using this methodology. Furthermore, MD simulations for drug design provide insights into the structural cavities required to design novel structures with higher affinity to the target. Also, the employment of MD simulations to drug design can help to refine the three-dimensional (3D) structure of targets in order to obtain a better sampling of the binding poses and more reliable affinity values with better structural advantages, because they incorporate some biological conditions that include structural motions compared to traditional docking procedures. This work analyzes the concepts and applicability of MD simulations for drug design because molecular structural motions are considered, and these help to identify hot spots, decipher structural details in the reported protein sites, as well as to eliminate sites that could be structural artifacts which could be originated from the structural characterization conditions from MD. Moreover, better free energy values for protein ligand recognition can also be obtained, and these can be validated under experimental procedures due to the robustness of the MD simulation methods.

  7. Equivalent Key Recovery Attack on H2-MAC Instantiated with MD5%H2-MAC-MD5的等价密钥恢复攻击

    H2-MAC was proposed by Kan Yasuda in Information Security Conference (ISC) 2009, which is similar with HMAC except that the outer key is omitted, and gets rid of the disadvantage of the key management. This paper presents the first equivalent key recovery attack on H2-MAC-MD5, which conduces to a selective forgery attack directly, while there only is a distinguishing attack for HMAC-MD5. Based on the distinguisher of HMAC-MD5, a pair of intermediate chaining variables, i.e., the equivalent keys, is detected which fulfils the specific conditions on the initial variables of the pseudo-collision. Then the inner key recovery attack on HMAC-MD5 is adopted to recover the equivalent key. Consequently, the adversary can process the selective forgery attack by computing the valid MAC value of M0||M*effortlessly, where M0 is a fixed one-block message, and M*can be any bit strings. The complexity of the attack is about 297 queries, which is much lower than the ideal complexity of the selective forgery.%H2-MAC由Kan Yasuda在ISC 2009上提出,与HMAC的不同之处在于H2-MAC没有外部密钥,简化密钥管理。首次给出 H2-MAC-MD5的等价密钥恢复攻击,并进行选择性伪造。基于HMAC-MD5区分器和比特探测技术,筛选可能满足特殊伪碰撞路线的中间链接变量,即等价密钥,并恢复其数值,导致选择性伪造。即在不知道密钥的前提下,敌手可伪造消息M0||M*的合法MAC值,其中,M0为固定的512比特消息分组,M*为任意消息。攻击的复杂度为297次MAC查询,远低于选择性伪造攻击的理想复杂度。

    Growing evidence indicates that angiotensin II (Ang II), a potent biologically active product of RAS, is a key regulator of renal inflammation and fibrosis. In this study, we tested the hypothesis that Ang II induces renal inflammatory injury and fibrosis through interaction with myeloid differentiation protein-2 (MD2), the accessory protein of toll-like receptor 4 (TLR4) of the immune system. Results indicated that in MD2−/− mice, the Ang II-induced renal fibrosis, inflammation and kidney dysfunction were significantly reduced compared to control Ang II-infused wild-type mice. Similarly, in the presence of small molecule MD2 specific inhibitor L6H21 or siRNA-MD2, the Ang II-induced increases of pro-fibrotic and pro-inflammatory molecules were prevented in tubular NRK-52E cells. MD2 blockade also inhibited activation of NF-κB and ERK. Moreover, MD2 blockade prevented the Ang II-stimulated formation of the MD2/TLR4/MyD88 signaling complex, as well as the increased surface binding of Ang II in NRK-52E cells. In addition, Ang II directly bound recombinant MD2 protein, rather than TLR4 protein. We conclude that MD2 is a significant contributor in the Ang II-induced kidney inflammatory injury in chronic renal diseases. Furthermore, MD2 inhibition could be a new and important therapeutic strategy for preventing progression of chronic renal diseases.

  9. Evaluation of hydroacid complex in the forward osmosis–membrane distillation (FO–MD) system for desalination

    The incorporation of membrane distillation (MD) into forward osmosis (FO) provides process sustainability to regenerate the draw solution and to produce clean water simultaneously. However, the reverse salt flux is the major hurdle in the FO-MD system because it not only reduces the effective osmotic driving force across the membrane but also increases the replenishment cost and scaling issue. For the first time, a hydroacid complex with abundant hydrophilic groups and ionic species is evaluated as the draw solutes in the hybrid FO-MD system consisting of multi-bore PVDF MD membranes for seawater/brackish desalination. In order to evaluate the practicality of the hydroacid complex in the FO-MD system, FO and MD experiments were conducted at elevated temperatures and concentrations. The hydroacid complex has displayed desired properties such as high solubility, low viscosity, excellent thermal stability and minimal reverse salt flux suitable for FO and MD operations. FO-MD desalination process was demonstrated with a highest seawater desalination flux of 6/32 LMH (FO/MD). This study may open up the prospective of employing the hydroacid complex as the draw solute in FO-MD hybrid systems for seawater /brackish desalination. © 2015 Elsevier B.V.

    Tonoplast transporters, including proton pumps and secondary transporters, are essential for plant cell function and for quality formation of fleshy fruits and ornamentals. Vacuolar transport of anthocyanins, malate, and other metabolites is directly or indirectly dependent on the H(+)-pumping activities of vacuolar H(+)-ATPase (VHA) and/or vacuolar H(+)-pyrophosphatase, but how these proton pumps are regulated in modulating vacuolar transport is largely unknown. Here, we report a transcription factor, MdMYB1, in apples that binds to the promoters of two genes encoding the B subunits of VHA, MdVHA-B1 and MdVHA-B2, to transcriptionally activate its expression, thereby enhancing VHA activity. A series of transgenic analyses in apples demonstrates that MdMYB1/10 controls cell pH and anthocyanin accumulation partially by regulating MdVHA-B1 and MdVHA-B2. Furthermore, several other direct target genes of MdMYB10 are identified, including MdVHA-E2, MdVHP1, MdMATE-LIKE1, and MdtDT, which are involved in H(+)-pumping or in the transport of anthocyanins and malates into vacuoles. Finally, we show that the mechanism by which MYB controls malate and anthocyanin accumulation in apples also operates in Arabidopsis (Arabidopsis thaliana). These findings provide novel insights into how MYB transcription factors directly modulate the vacuolar transport system in addition to anthocyanin biosynthesis, consequently controlling organ coloration and cell pH in plants.

  11. A Study of the Adsorption of Molecular Deposition Filming Flooding Agent MD-1 on Quartz Sand

    2004-01-01

    Molecular deposition filming flooding (MDFF) is a novel oil recovery technique based on the thermopositive monolayer electrostatic adsorption of the MDFF agent on different interfaces within reservoir systems. In this paper, the adsorption property of the MDFF agent, MD-I, on quartz sand has been studied through adsorption experiments at different pH and temperatures. Experimental data are also analyzed kinetically and thermodynamically. The results show that the adsorption of MD-I on quartz sand takes place mainly because of electrostatic interactions, which corresponds to adsorption that increases with pH. Kinetic analyses show that at a higher pH the activation energy for adsorption gets lower and, therefore, the adsorption becomes quicker for MD-1 on quartz sand. Thermodynamic analyses show that pH plays an important role in the adsorption of MD-1 on quartz sand. At a higher pH, more negative surface charges result in the increase of electrostatic interactions between MD-1 and quartz sand. Therefore, the saturated adsorption amount increases and more adsorption heat will be released.

  12. Chosen-Prefix Collisions for MD5 and Colliding X.509 Certificates for Different Identities

    Science.gov (United States)

    Stevens, Marc; Lenstra, Arjen; de Weger, Benne

    We present a novel, automated way to find differential paths for MD5. As an application we have shown how, at an approximate expected cost of 250 calls to the MD5 compression function, for any two chosen message prefixes P and P', suffixes S and S' can be constructed such that the concatenated values P||S and P'||S' collide under MD5. Although the practical attack potential of this construction of chosen-prefix collisions is limited, it is of greater concern than random collisions for MD5. To illustrate the practicality of our method, we constructed two MD5 based X.509 certificates with identical signatures but different public keys and different Distinguished Name fields, whereas our previous construction of colliding X.509 certificates required identical name fields. We speculate on other possibilities for abusing chosen-prefix collisions. More details than can be included here can be found on www.win.tue.nl/hashclash/ChosenPrefixCollisions/.

  13. Crystal twinning of human MD-2 recognizing endotoxin cores of lipopolysaccharide

    Twinned crystals of humaan MD-2 are transformed into single crystals with cryoprotectant optimization. Twinning of crystals causes overlapping of two or more reciprocal lattice points, and hence structure amplitudes for a single crystalline domain are hardly obtained from X-ray diffraction intensities. MD-2 protein forms a stable complex with Toll-like receptor 4 and recognizes bacterial lipopolysaccharide (LPS). Excessive immune responses activated by LPS cause septic shocks. Saccharide-trimmed human MD-2 crystallizes in the tetragonal form with apparent Laue symmetry of 4/mmm, and diffraction intensities from these crystals indicate crystal twinning. The crystal consists of two different domains, A and B. The c{sub A} axis of domain A coincides with the c{sub B} axis of domain B with a smaller lattice, and the a{sub A} axis corresponds to the (a{sub B} + b{sub B}) axis. This twinning severely imposes difficulty in structure determination. Through optimization of cryoprotectant, domain A was thoroughly transformed into domain B. The crystal containing only domain B is in space group P4{sub 1}2{sub 1}2 with one MD-2 molecule in the asymmetric unit. The structure of this form of MD-2 as well as its complex with antiendotoxic lipid IVa was successfully determined using the multiple isomorphous replacement method.

    Full Text Available Neste artigo, analiso como brasileiras de classes média e média alta em Los Angeles lidam com o fenômeno da exotização das suas imagens. Observo que, embora originalmente articuladas a partir de Hollywood (Carmen Miranda nos limites da hierarquia entre as nações e do colonialismo, essas imagens são hoje alimentadas e recriadas também pelos próprios brasileiros. Uma das idéias centrais que defendo aqui é que embora tais imagens inicialmente restrinjam a ação das brasileiras, uma vez que sempre impõem o diálogo com os seus conteúdos, elas não o fazem permanentemente, ou seja, no processo de integração há espaço para a negociação de outras imagens e conteúdos e isto depende de fatores que vão além da exotização em si.This article discusses how middle and upper-middle class Brazilian women deal with their exoticized images in Los Angeles. It points out that although originally articulated from Hollywood (Carmen Miranda, within the limits of the hierarchy of nations and colonialism, today these images are also fed and recreated by Brazilians. One of the central ideas presented is that, despite constraining the movements and actions of the women, imposing on them the need to dialogue with their content, these exotic images do not do it permanently. In other words, in the process of integration, there is always room for negotiation of other images and contents that depend on factor other than exoticization itself.

    A seismic refraction and low-fold reflection survey, known as the Los Angeles Region Seismic Experiment (LARSE), was conducted along a transect (line 1) extending from Seal Beach, California, to the Mojave Desert, crossing the Los Angeles and San Gabriel Valley basins and San Gabriel Mountains. The chief result of this survey is an interpreted cross section that addresses a number of questions regarding the crustal structure and tectonics of southern California that have been debated for decades and have important implications for earthquake hazard assessment. The results (or constraints) are as follows. (1) The maximum depth of the Los Angeles basin along line 1 is 8 9 km. (2) The deep structure of the Sierra Madre fault zone in the northern San Gabriel Valley is as follows. The Duarte branch of the Sierra Madre fault zone forms a buried, 2.5-km-high, moderately north dipping buttress between the sedimentary and volcanic rocks of the San Gabriel Valley and the igneous and metamorphic rocks of the San Gabriel Mountains. (For deeper structure, see following.) (3) There are active crustal décollements in southern California. At middle-crustal depths, the Sierra Madre fault zone appears to sole into a master décollement that terminates northward at the San Andreas fault and projects southward beneath the San Gabriel Valley to the Puente Hills blind thrust fault. (4) The dip and depth extent of the San Andreas fault along line 1 dips steeply (˜83°) northward and extends to at least the Moho. (5) The subsurface lateral extent of the Pelona Schist in southern California is as follows. Along line 1, the Pelona Schist underlies much, if not all of the San Gabriel Mountains south of the San Andreas fault to middle-crustal depths. North of the San Andreas fault, it is apparently not present along the transect.

  1. Spatial patterns and source attribution of urban methane in the Los Angeles Basin

    Urban areas are increasingly recognized as a globally important source of methane to the atmosphere; however, the location of methane sources and relative contributions of source sectors are not well known. Recent atmospheric measurements in Los Angeles, California, USA, show that more than a third of the city's methane emissions are unaccounted for in inventories and suggest that fugitive fossil emissions are the unknown source. We made on-road measurements to quantify fine-scale structure of methane and a suite of complementary trace gases across the Los Angeles Basin in June 2013. Enhanced methane levels were observed across the basin but were unevenly distributed in space. We identified 213 methane hot spots from unknown emission sources. We made direct measurements of ethane to methane (C2H6/CH4) ratios of known methane emission sources in the region, including cattle, geologic seeps, landfills, and compressed natural gas fueling stations, and used these ratios to determine the contribution of biogenic and fossil methane sources to unknown hot spots and to local urban background air. We found that 75% of hot spots were of fossil origin, 20% were biogenic, and 5% of indeterminate source. In regionally integrated air, we observed a wider range of C2H6/CH4 values than observed previously. Fossil fuel sources accounted for 58-65% of methane emissions, with the range depending on the assumed C2H6/CH4 ratio of source end-members and model structure. These surveys demonstrated the prevalence of fugitive methane emissions across the Los Angeles urban landscape and suggested that uninventoried methane sources were widely distributed and primarily of fossil origin.

    Full Text Available The Los Angeles basin is a significant anthropogenic source of major greenhouse gases (CO2 and CH4 and the pollutant CO, contributing significantly to regional and global climate change. We present a novel approach for monitoring the spatial and temporal distributions of greenhouse gases in the Los Angeles basin using a high-resolution spectroscopic remote sensing technique. A new Fourier Transform Spectrometer called CLARS-FTS has been deployed since May 2010 at JPL's California Laboratory for Atmospheric Remote Sensing (CLARS on Mt. Wilson, California for automated long-term measurements of greenhouse gases. The instrument design and performance of CLARS-FTS are presented. From its mountaintop location at an altitude of 1673 m, the instrument points at a programmed sequence of ground target locations in the Los Angeles basin, recording spectra of reflected near-IR solar radiation. Column-averaged dry-air mole fractions of greenhouse gases (XGHG including XCO2, XCH4, and XCO are retrieved several times per day for each target. Spectra from a local Spectralon® scattering plate are also recorded to determine background (free tropospheric column abundances above the site. Comparisons between measurements from LA basin targets and the Spectralon® plate provide estimates of the boundary layer partial column abundances of the measured species. Algorithms are described for transforming the measured interferograms into spectra, and for deriving column abundances from the spectra along with estimates of the measurement precision and accuracy. The CLARS GHG measurements provide a means to infer relative, and possibly absolute, GHG emissions.

    The behaviour of sheared colloidal suspensions with full hydrodynamic interactions (HIs) is numerically studied. To this end, we use the hybrid stochastic rotation dynamics-molecular dynamics (SRD-MD) method. The shear viscosity of colloidal suspensions is computed for different volume fractions, both for dilute and concentrated cases. We verify that HIs help in the collisions and the streaming of colloidal particles, thereby increasing the overall shear viscosity of the suspension. Our results show a good agreement with known experimental, theoretical, and numerical studies. This work demonstrates the ability of SRD-MD to successfully simulate transport coefficients that require correct modelling of HIs.

  7. MD-2 Residues Tyrosine 42, Arginine 69, Aspartic Acid 122, and Leucine 125 Provide Species Specificity for Lipid IVA*

    2010-01-01

    Lipopolysaccharide (LPS) activates the innate immune response through the Toll-like receptor 4 (TLR4)·MD-2 complex. A synthetic lipid A precursor, lipid IVA, induces an innate immune response in mice but not in humans. Both TLR4 and MD-2 are required for the agonist activity of lipid IVA in mice, with TLR4 interacting through specific surface charges at the dimerization interface. In this study, we used site-directed mutagenesis to identify the MD-2 residues that determine lipid IVA species specificity. A single mutation of murine MD-2 at the hydrophobic pocket entrance, E122K, substantially reduced the response to lipid IVA. Combining the murine MD-2 E122K with the murine TLR4 K367E/S386K/R434Q mutations completely abolished the response to lipid IVA, effectively converting the murine cellular response to a human-like response. In human cells, however, simultaneous mutations of K122E, K125L, Y41F, and R69G on human MD-2 were required to promote a response to lipid IVA. Combining the human MD-2 quadruple mutations with the human TLR4 E369K/Q436R mutations completely converted the human MD-2/human TLR4 receptor to a murine-like receptor. Because MD-2 residues 122 and 125 reside at the dimerization interface near the pocket entrance, surface charge differences here directly affect receptor dimerization. In comparison, residues 42 and 69 reside at the MD-2/TLR4 interaction surface opposite the dimerization interface. Surface charge differences there likely affect the binding angle and/or rigidity between MD-2 and TLR4, exerting an indirect influence on receptor dimerization and activation. Thus, surface charge differences at the two MD-2/TLR4 interfaces determine the species-specific activation of lipid IVA. PMID:20592019

    An audit of recreation programs with moderate or higher levels of physical activity (PA) in Los Angeles area cities (N=82) was conducted using internet, telephone, and survey methods. Metabolic Equivalents (METs) were used to code programs׳ physical activity intensity. MET-hours per recreation program was associated with required age for enrollment, percent of residents >64 years of age, and fiscal capacity of cities. Capacity to promote energy expenditure may depend on targeted age groups, age of population, and municipal fiscal capacity. Cities with lower fiscal capacity might offer those higher MET-hour activities which require less specialized equipment and seek outside funding to offer higher MET programs.

    Ethnographic methods were used to study daily occupations and weekly routines of four young Orthodox Jewish couples living in Los Angeles. Data from interviews and participant observation demonstrate the importance to the couples of fulfilling God's commandments [Hebrew, mitzvot], which organize and sanctify the otherwise mundane activities of daily living, such as eating, bathing sleeping, and rising. The article focuses on the couples' experiences in (a) observing the Sabbath, (b) studying and praying, and (c) keeping a kosher home. Orthodox Jewish ritual, practice, and spirituality are time bound and action oriented. Occupational therapists can benefit from understanding how Orthodox Jews invest and experience spiritual meaning in seemingly mundane occupations and routines.

  12. Differentiating Tectonic and Anthropogenic Earthquakes in the Greater Los Angeles Basin, Southern California

    2014-12-01

    The 2014 flurry of moderate earthquakes in the Los Angeles region raised the concern if some of this or past seismicity was of anthropogenic origin as opposed to being caused by ongoing transpressional tectonics. The Mw5.1 La Habra sequence is located near several major oil fields but the Mw4.4 Encino sequence was located away from oil fields, within the Santa Monica Mountains. The last century of seismicity in the Los Angeles area consists of numerous small and large earthquakes. Most of these earthquakes occur beneath the basin sediments and are associated with transpressional tectonics, related to the big bend in the San Andreas fault, but some could be associated with large oil fields. In particular, both the 1933 Mw6.4 Long Beach and the 1987 Mw5.9 Whittier Narrows earthquakes were spatially associated with two major oil fields, the Huntington Beach and Montebello fields. Numerous large oil fields have been in production for more than 125 years. The geographical locations of the oil fields follow major tectonic trends such as the Newport-Inglewood fault, the Whittier fault, and the thrust belt located at the north edge of the Los Angeles basin. More than 60 fields have oil wells and some of these have both disposal and fracking wells. Before fluid injection became common, Kovach (1974) documented six damaging events induced by fluid extraction from 1947 to 1961 in the Wilmington oil field. Since 1981 the waveform-relocated earthquake catalog for the Los Angeles basin is complete on the average above M2.0. We compare the spatial distribution of these events and the proximity of nearby active oil fields. We will also analyze the seismicity in the context of available monthly fluid extraction and injection volumes and search for temporal correlations. The La Habra sequence apparently correlates with temporal changes in extraction and injection volumes in the Santa Fe Springs oil field but not with activities in other oil fields within closer spatial proximity.

  13. Notes from the field: identification of a Taenia tapeworm carrier - Los Angeles County, 2014.

    Carriers of the pork tapeworm, Taenia solium, are the sole source of cysticercosis, a parasitic tissue infection. When tapeworm eggs excreted by the carrier are ingested, tapeworm larvae can form cysts. When cysts form in the brain, the condition is called neurocysticercosis and can be especially severe. In Los Angeles County an average of 136 county residents are hospitalized with neurocysticercosis each year. The prevalence of Taenia solium carriage is largely unknown because carriage is asymptomatic, making detection difficult. The identification and treatment of tapeworm carriers is an important public health measure that can prevent additional neurocysticercosis cases.

    2014-06-05

    We assessed public opinion on nutrition-related policies to address child obesity: a soda tax, restrictions on advertising unhealthy foods and beverages to children, and restrictions on siting fast food restaurants and convenience stores near schools. We analyzed data from 998 adults (aged ≥18 years) in the 2011 Los Angeles County Health Survey. Support was highest for advertising restrictions (74%), intermediate for a soda tax (60%), and lowest for siting restrictions on fast food restaurants and convenience stores (44% and 37%, respectively). Support for food and beverage advertising restrictions and soda taxation is promising for future policy efforts to address child obesity.

    TFL1 is known as a floral repressor in Arabidopsis thaliana (L.) Heynh. In apple there are two TFL1 homologs, MdTFL1-1 and MdTFL1-2. The MdTFL1-1 gene was silenced in transgenic clones expressing a hairpin gene construct of a 323 bp fragment of MdTFL1-1. The hairpin gene construct was transferred to three different apple genotypes. Of 22 transgenic clones, 21 showed a significant reduction in MdTFL1-1 mRNA expression. Precocious flowering was obtained for 20 clones, which flowered already during in vitro cultivation. Nineteen clones could successfully be transferred to the greenhouse where 18 of them flowered within a few weeks followed by the death or at least a strongly inhibited vegetative growth of the plant. Most of the transgenic flowers developed abnormally. Results obtained on greenhouse-grown plants of the transgenic clones and transgenic seedlings clearly demonstrated the major role of MdTFL1 genes in maintaining the vegetative growth as prerequisite for a perennial lifecycle. It was shown that MdTFL1 dsRNAi promotes a life history similar to annual plants. Preliminary results obtained from grafting experiments with non-transgenic scions grafted onto MdTFL1 dsRNAi transgenic rootstocks indicated that the flower-inducing signal obtained after silencing of MdTFL1 genes seems not to be graft-transmissible.

    2014-11-01

    Spiritual coping is associated with positive mental health outcomes for individuals with serious mental illness, yet spirituality-infused services are seldom offered in public sector mental health agencies. The Los Angeles County Department of Mental Health introduced a policy addressing spirituality in 2012. This study explored the breadth and degree to which spirituality-infused activities were being offered in 53 Los Angeles wellness and recovery centers after the policy was widely disseminated. More than 98 % of the centers offered options for spirituality-infused activities; one-third offered spirituality-focused groups. Los Angeles's progress may guide implementation of spirituality-infused services in other state or local public mental health systems.

  18. Organochlorine contaminants and maternal offloading in the lecithotrophic Pacific angel shark (Squatina californica) collected from southern California.

    Lyons, Kady; Lowe, Christopher G

    2015-08-15

    Pacific angel sharks (Squatina californica) are a benthic elasmobranch that occupy intermediate trophic level positions in coastal food webs. Angel sharks' life history characteristics make them susceptible to accumulating high amounts of contaminants. Four angel sharks were opportunistically captured in southern California and their liver and uterine contents were analyzed for PCBs, DDTs and other pesticides. High DDT:PCB ratios were found in the sharks indicating direct or indirect foraging near a local EPA Superfund Site. Organic contaminants were measured in ovulated eggs, indicating that females are able to maternally offload contaminants. Despite the potential mismatch between ovarian and uterine fecundity, we estimated females to offload approximately 13±5% of their total body load, which represents the upper limit of this capability. Although low in sample size, the initial findings from this study suggest that habitat use might play an important role in contaminant accumulation in this species.

    Racial and ethnic disparities in utilization of chiropractic services have been described at the state level, but little is known about such local disparities. We analyzed Medicare data for the year 2008 to evaluate by ZIP code for utilization of chiropractic services among older adults in Los Angeles County, California. We evaluated for availability and use of chiropractic services by racial/ethnic category, quantified geographic variations by coefficient of variation, and mapped utilization by selected racial/ethnic categories. Among 7502 beneficiaries who used chiropractic services, 72% were white, 12% Asian, 1% black, 1% Hispanic, and 14% other/unknown. Variation in the number of beneficiaries per ZIP code who used chiropractic services was highest among Hispanics, blacks, and Asians. We found evidence of racial disparities in use of chiropractic services at the local level in Los Angeles County. Older blacks and Hispanics in Los Angeles County may be underserved with regard to chiropractic care.

  1. Vienna-PTM web server: a toolkit for MD simulations of protein post-translational modifications

    Science.gov (United States)

    Margreitter, Christian; Petrov, Drazen; Zagrovic, Bojan

    2013-01-01

    Post-translational modifications (PTMs) play a key role in numerous cellular processes by directly affecting structure, dynamics and interaction networks of target proteins. Despite their importance, our understanding of protein PTMs at the atomistic level is still largely incomplete. Molecular dynamics (MD) simulations, which provide high-resolution insight into biomolecular function and underlying mechanisms, are in principle ideally suited to tackle this problem. However, because of the challenges associated with the development of novel MD parameters and a general lack of suitable computational tools for incorporating PTMs in target protein structures, MD simulations of post-translationally modified proteins have historically lagged significantly behind the studies of unmodified proteins. Here, we present Vienna-PTM web server (http://vienna-ptm.univie.ac.at), a platform for automated introduction of PTMs of choice to protein 3D structures (PDB files) in a user-friendly visual environment. With 256 different enzymatic and non-enzymatic PTMs available, the server performs geometrically realistic introduction of modifications at sites of interests, as well as subsequent energy minimization. Finally, the server makes available force field parameters and input files needed to run MD simulations of modified proteins within the framework of the widely used GROMOS 54A7 and 45A3 force fields and GROMACS simulation package.

    2008-05-01

    Full Text Available Abstract Background Recent advances in global genomic profiling methodologies have enabled multi-dimensional characterization of biological systems. Complete analysis of these genomic profiles require an in depth look at parallel profiles of segmental DNA copy number status, DNA methylation state, single nucleotide polymorphisms, as well as gene expression profiles. Due to the differences in data types it is difficult to conduct parallel analysis of multiple datasets from diverse platforms. Results To address this issue, we have developed an integrative genomic analysis platform MD-SeeGH, a software tool that allows users to rapidly and directly analyze genomic datasets spanning multiple genomic experiments. With MD-SeeGH, users have the flexibility to easily update datasets in accordance with new genomic builds, make a quality assessment of data using the filtering features, and identify genetic alterations within single or across multiple experiments. Multiple sample analysis in MD-SeeGH allows users to compare profiles from many experiments alongside tracks containing detailed localized gene information, microRNA, CpG islands, and copy number variations. Conclusion MD-SeeGH is a new platform for the integrative analysis of diverse microarray data, facilitating multiple profile analyses and group comparisons.

    We report on observations of near-Earth asteroid 2011 MD with the Spitzer Space Telescope. We have spent 19.9 hr of observing time with channel 2 (4.5 μm) of the Infrared Array Camera and detected the target within the 2σ positional uncertainty ellipse. Using an asteroid thermophysical model and a model of nongravitational forces acting upon the object, we constrain the physical properties of 2011 MD, based on the measured flux density and available astrometry data. We estimate 2011 MD to be (6{sub −2}{sup +4}) m in diameter with a geometric albedo of 0.3{sub −0.2}{sup +0.4} (uncertainties are 1σ). We find the asteroid's most probable bulk density to be (1.1{sub −0.5}{sup +0.7}) g cm{sup –3}, which implies a total mass of (50-350) t and a macroporosity of ≥65%, assuming a material bulk density typical of non-primitive meteorite materials. A high degree of macroporosity suggests that 2011 MD is a rubble-pile asteroid, the rotation of which is more likely to be retrograde than prograde.

    2016-01-01

    The introduction of the elite pineapple variety, MD-2, has caused a significant market shift in the pineapple industry. Better productivity, overall increased in fruit quality and taste, resilience to chilled storage and resistance to internal browning are among the key advantages of the MD-2 as compared with its previous predecessor, the Smooth Cayenne. Here, we present the genome sequence of the MD-2 pineapple (Ananas comosus (L.) Merr.) by using the hybrid sequencing technology from two highly reputable platforms, i.e. the PacBio long sequencing reads and the accurate Illumina short reads. Our draft genome achieved 99.6% genome coverage with 27,017 predicted protein-coding genes while 45.21% of the genome was identified as repetitive elements. Furthermore, differential expression of ripening RNASeq library of pineapple fruits revealed ethylene-related transcripts, believed to be involved in regulating the process of non-climacteric pineapple fruit ripening. The MD-2 pineapple draft genome serves as an example of how a complex heterozygous genome is amenable to whole genome sequencing by using a hybrid technology that is both economical and accurate. The genome will make genomic applications more feasible as a medium to understand complex biological processes specific to pineapple. PMID:27374615

    2009-09-01

    Fermentation processes using taxol-producing fungi other than Taxus spp. may be an alternative way to produce taxol, which is an important antitumor agent used widely in the clinic setting. In this study, a taxol-producing endophytic fungus strain MD2 was isolated from the inner bark of Taxus media. Strain MD2 produced taxol when grown in potato dextrose liquid medium. The fungal taxol-which was analyzed by ultraviolet, high-performance liquid chromatography and mass spectrometry-was shown to be identical to authentic taxol and 10-deacetylbaccatin III. Further analysis with nuclear magnetic resonance (NMR) spectroscopy to show the chemical structure of the fungal taxol indicated that the fungal taxol produced an NMR spectrum identical to that of authentic taxol. Strain MD2 was identified as Cladosporium cladosporioides according to morphology of the fungal culture, characteristics of the spores, and analysis of 18S rDNA sequence. In addition, 10-deacetylbaccatin III-10-O-acetyl transferase gene of C. cladosporioides MD2 was cloned for the first time and was shown to share 99% identity with that of T. x media and 97% identity with that of T. wallichiana var. mairei.

    2015-12-01

    Full Text Available Dog relinquishment is a large component of shelter intake in the United States. Research has shown traits of the dog are associated with relinquishment as well as general characteristics of those relinquishing. Low income is often cited as a risk factor for relinquishment. The majority of people with lower incomes, however, do not relinquish. A group of people accessing a shelter in a low socioeconomic region of Los Angeles to relinquish their dogs was surveyed. This study examined risk factors for relinquishment, controlling for household income, compared to a group utilizing low cost spay/neuter services. A total of 76.9% of those relinquishing noted cost as a reason for relinquishment. Of participants in the relinquishment group, 80.7% reported not being aware of any services available to them. Most notable in the findings was that the odds of relinquishment were generally higher as the amount of perceived stress in the home in the past three months increased. The majority of people in both groups reported being emotionally attached to the dog. In this sample from a South Los Angeles community, the majority of reasons for relinquishment were likely solvable with assistance. These findings highlight an opportunity to assess community needs and provide community specific alternatives to relinquishment.

    2013-05-01

    During the CalNex (California Research at the Nexus of Air Quality and Climate Change) field study in May-June 2010, measurements of volatile organic compounds (VOCs) were performed in the Los Angeles (LA) basin onboard a NOAA research aircraft and at a ground site located in Pasadena. A weekday-weekend effect in ozone, caused by lower NOx emissions due to reduced diesel truck traffic in the weekends, has been previously observed in Los Angeles and other cities. Measurements in the Caldecott tunnel show that emission ratios of VOCs do not vary with the day of the week, but measurements during CalNex2010 show a VOC weekday-weekend effect through faster photochemical processing at lower ambient NOx mixing ratios. Ambient VOC enhancement ratios of long-lived species such as benzene are the same between weekdays and weekends, whereas enhancement ratios of short-lived species, such as trimethyl benzene, are up to a factor of three lower on weekends. Based upon the observed differences in VOC enhancement ratios to CO, we determine that photochemical processing was on average 65%-75% faster on weekends during CalNex2010, which indicates that ambient OH radical concentrations were larger by this factor causing the observed change in VOC composition. A box model calculation based on the Master Chemical Mechanism was used to verify the increase in photochemical processing in the weekends.

    Methane is a powerful greenhouse gas and an important contributor to global warming. Recent studies have suggested that methane emissions in large cities are underestimated with several models even indicating that substantial emissions attributed to cities are in part from regional and/or encroaching agricultural sources rather than from urban fossil fuel sources. We have found that stable isotopes (13-C and D) and radiocarbon (C-14) are excellent tracers of various sources of methane in Los Angeles, California. Measurements of the d13C and dD of methane from discrete sources show excellent separation between urban sources, such as vehicle emissions, power plants, oil refineries, landfills, and sewage treatment plants and agricultural sources like cows, biogas, and cattle feedlots. In addition, radiocarbon is an excellent tracer of modern versus fossil fuel contributions to methane emissions in the region. Preliminary measurements of background air in Los Angeles indicate that the major source of excess methane is vehicle emissions with most additional CH4 likely contributed from among other fossil fuel sources such as oil refining or power plants. We are currently confirming these results with broader field campaigns and additional measurements, including continuous measurements of atmospheric methane concentration using tunable laser spectroscopy. The combination of high-resolution tunable laser concentration measurements and precise isotope measurements using mass spectrometry is a very promising and powerful tool for methane source monitoring.

    Full Text Available The purpose of this paper is to analyze whether Angel Investment (AI may serve as a suitable tool for the early-stage market of Kosovo. The activity of the Business Angel (BA has experienced significant development lately, and moreover, supplementary attention by policymakers all over Europe and beyond. As a result, the BA community in Europe has published the Start-up Investor Manifesto in May 2014 aiming to adopt policies and actions towards the rise of entrepreneurship and innovation through the creation of 1.5 million new jobs in Europe by 2017. In addition, the Manifesto foresees enlargement of cross-border activity of BAs, including the emerging markets lying outside EU borders. Based on its increasing capacity and attention paid to, and on the fact that over 98% of registered Kosovar businesses are micro enterprises, AI may appear an appropriate instrument in advancing country’s early-stage market. Therefore, this paper intends to answer this interrogation by simultaneously studying the scientific arguments as well as best practices regarding AI both in developed and emerging markets. Accordingly it aims to provide a model on how the AI market could be developed in Kosovo.

  8. The conundrum of police officer-involved homicides: Counter-data in Los Angeles County

    Full Text Available This paper draws from critical data studies and related fields to investigate police officer-involved homicide data for Los Angeles County. We frame police officer-involved homicide data as a rhetorical tool that can reify certain assumptions about the world and extend regimes of power. We highlight the possibility that this type of sensitive civic data can be investigated and employed within local communities through creative practice. Community involvement with data can create a countervailing force to powerful dominant narratives and supplement activist projects that hold local officials accountable for their actions. Our analysis examines four Los Angeles County police officer-involved homicide data sets. First, we provide accounts of the semantics, granularity, scale and transparency of this local data. Then, we describe a “counter data action,” an event that invited members of the community to identify the limits and challenges present in police officer-involved homicide data and to propose new methods for deriving meaning from these indicators and statistics.

  9. Measles outbreak associated with an arriving refugee - Los Angeles County, California, August-September 2011.

    Measles is a highly communicable, acute viral illness with potential for severe complications, including death. Although endemic measles was eliminated in the United States in 2000 as a result of widespread vaccination, sporadic measles outbreaks still occur, largely associated with international travel from measles-endemic countries and pockets of unvaccinated persons. On August 26, 2011, the Los Angeles County Department of Public Health (LACDPH) was notified of suspected measles in a refugee from Burma who had arrived in Los Angeles, California, on August 24, after a flight from Kuala Lumpur, Malaysia. Passengers on the flight included 31 other refugees who then traveled to seven other states, widening the measles investigation and response activities. In California alone, 50 staff members from LACDPH and the California Department of Public Health (CDPH) interviewed and reinterviewed 298 contacts. Measles was diagnosed in three contacts of the index patient (patient A). The three contacts with measles were two passengers on the same flight as patient A and a customs worker; no secondary cases were identified. Delayed diagnosis of measles in patient A and delayed notification of health officials precluded use of measles-mumps-rubella (MMR) vaccine as an outbreak intervention. This outbreak emphasizes the importance of maintaining a high level of vaccination coverage and continued high vigilance for measles in the United States, particularly among incoming international travelers; clinicians should immediately isolate persons with suspected measles and promptly report them to health authorities.

  10. Playa Del Rey oil field, Los Angeles County, California-- natural gas storage

    The Playa del Rey oil field is on Santa Monica Bay, about 15 miles SW. of Los Angeles. The sedimentary rocks of the field were deposited on the flanks and over the ridge of an erosional surface of Franciscan schist. A NW.-trending anticline resulted from deposition and compaction over the ridge. An apron of schistose clastic material was deposited in the littoral zone at the base of the ridge and in embayments formed by the lateral channels. Conformably overlying the basal conglomerate (productive lower zone) and unconformably overlying the schist is a dark brown, compact shale with abundant small lenticular streaks and nodules of calcium phosphate. The rest of the Miocene rock column is composed of about 500 ft of hard, compact black shale and sandy shale, which is conformably overlain by the typical Los Angeles-basin Pliocene and Pleistocene rocks. The upper oil zone is in the lower Pliocene. The Playa del Rey Field is productive from both the lower zone and from sedimentary rocks of the anticline. There are widely varied porosity and permeability values throughout the Del Rey Hills area. That part chosen for the gas-storage project is where the basal conglomerate overlying the Franciscan schist is overlain by the nodular shale.

    Full Text Available The aim of the research is to identify some characters in the novel Where Angels Fear to Tread in teaching literary works. In learning of characters, someone will understand about the term of the interests, desires, emotions, and moral those form the individual within a story. Library research was used in thid study. The experts divide characters become two characters; they are central characters and additional characters. Central characters are a character who takes the greatest part in the main character or a figure that is most telling. Volume appearance of the main character more than the other characters. Meanwhile, additional characters or subordinate figures are figures that appear once or several times, figures that support or assist the central figure. In the novel Where Angels Fear To Tread, writer found some figures or characters such as: Mrs. Herriton, Lilia, Philip, Gino, and Carroline Abbot. Each of them had different characters; Mrs Herriton was a selfish and arrogant because she came from a high social status. Lilia was a patient and never denied what was ruled by her mother in-low although sometimes she was often treated her like slaves. Philip was figured as a handsome man, his tolerance and empathy were high. Gino was figured as stupid character. Miss Abbott as a nice, quiet, dull, and friendly.

    The present study investigated stocking density and genetic lines, factors that may alter the severity and incidence of angel wing (AW), in White Roman geese. Geese (n = 384) from two genetically selected lines (normal- winged line, NL, and angel-winged line, AL, respectively) and one commercial line (CL) were raised in four pens. Following common commercial practice, low-stocking-density (LD), medium-stocking-density, and high-stocking-density treatments were respectively administered to 24, 32, and 40 geese per pen at 0 to 3 weeks (1.92 m(2)/pen) and 4 to 6 weeks (13.2 m(2)/pen) of age and to 24, 30, and 36 geese at 7 to 14 weeks (20.0 m(2)/pen) of age. The results revealed that stocking density mainly affected body weight gain in geese younger than 4 weeks, and that geese subjected to LD had a high body weight at 2 weeks of age. However, the effect of stocking density on the severity score of AW (SSAW) and incidence of AW (IAW) did not differ significantly among the treatments. Differences were observed among the genetic stocks; that is, SSAW and IAW were significantly higher in AL than in NL and CL. Genetic selection generally aggravates AW, complicating its elimination. To effectively reduce IAW, stocking density, a suspected causal factor, should be lower than that presently applied commercially.

    Due to the limited resolution at depth of geodetic and other geophysical data, the geometry and the loading rate of the ramp-décollement faults below the metropolitan Los Angeles are poorly understood. Here we complement these data by assuming conservation of motion across the Big Bend of the San Andreas Fault. Using a Bayesian approach, we constrain the geometry of the ramp-décollement system from the Mojave block to Los Angeles and propose a partitioning of the convergence with 25.5 ± 0.5 mm/yr and 3.1 ± 0.6 mm/yr of strike-slip motion along the San Andreas Fault and the Whittier Fault, with 2.7 ± 0.9 mm/yr and 2.5 ± 1.0 mm/yr of updip movement along the Sierra Madre and the Puente Hills thrusts. Incorporating conservation of motion in geodetic models of strain accumulation reduces the number of free parameters and constitutes a useful methodology to estimate the tectonic loading and seismic potential of buried fault networks.

  14. Identification of key residues that confer Rhodobacter sphaeroides LPS activity at horse TLR4/MD-2.

    Directory of Open Access Journals (Sweden)

    Katherine L Irvine

    Full Text Available The molecular determinants underpinning how hexaacylated lipid A and tetraacylated precursor lipid IVa activate Toll-like receptor 4 (TLR4 are well understood, but how activation is induced by other lipid A species is less clear. Species specificity studies have clarified how TLR4/MD-2 recognises different lipid A structures, for example tetraacylated lipid IVa requires direct electrostatic interactions for agonism. In this study, we examine how pentaacylated lipopolysaccharide from Rhodobacter sphaeroides (RSLPS antagonises human TLR4/MD-2 and activates the horse receptor complex using a computational approach and cross-species mutagenesis. At a functional level, we show that RSLPS is a partial agonist at horse TLR4/MD-2 with greater efficacy than lipid IVa. These data suggest the importance of the additional acyl chain in RSLPS signalling. Based on docking analysis, we propose a model for positioning of the RSLPS lipid A moiety (RSLA within the MD-2 cavity at the TLR4 dimer interface, which allows activity at the horse receptor complex. As for lipid IVa, RSLPS agonism requires species-specific contacts with MD-2 and TLR4, but the R2 chain of RSLA protrudes from the MD-2 pocket to contact the TLR4 dimer in the vicinity of proline 442. Our model explains why RSLPS is only partially dependent on horse TLR4 residue R385, unlike lipid IVa. Mutagenesis of proline 442 into a serine residue, as found in human TLR4, uncovers the importance of this site in RSLPS signalling; horse TLR4 R385G/P442S double mutation completely abolishes RSLPS activity without its counterpart, human TLR4 G384R/S441P, being able to restore it. Our data highlight the importance of subtle changes in ligand positioning, and suggest that TLR4 and MD-2 residues that may not participate directly in ligand binding can determine the signalling outcome of a given ligand. This indicates a cooperative binding mechanism within the receptor complex, which is becoming increasingly

    The Los Angeles Basin is a densely populated coastal area that significantly depends on groundwater. A part of this groundwater supply is at risk from saltwater intrusion-the impetus for this study. High-resolution seismic-reflection data collected from the Los Angeles-Long Beach Harbor Complex have been combined with borehole geophysical and descriptive geological data from four nearby ??400-m-deep continuously cored wells and with borehole geophysical data from adjacent water and oil wells to characterize the Pliocene to Holocene stratigraphy of the Dominguez Gap coastal aquifer system. The new data are shown as a north-south, two- dimensional, sequence-stratigraphic model that is compared to existing lithostratigraphic models of the Los Angeles Basin in an attempt to better understand pathways of saltwater intrusion into coastal aquifers. Intrusion of saltwater into the coastal aquifer system generally is attributed to over-pumping that caused the hydraulic gradient to reverse during the mid-1920s. Local water managers have used the existing lithostratigraphic model to site closely spaced injection wells of freshwater (barrier projects) attempting to hydraulically control the saltwater intrusion. Improved understanding of the stratigraphic relationships can guide modifications to barrier design that will allow more efficient operation. Allostratigraphic nomenclature is used to define a new sequence-stratigraphic model for the area because the existing lithostratigraphic correlations that have been used to define aquifer systems are shown not to be time-correlative. The youngest sequence, the Holocene Dominguez sequence, contains the Gaspur aquifer at its base. The Gaspur aquifer is intruded with saltwater and consists of essentially flat-lying gravelly sands deposited by the ancestral Los Angeles River as broad channels that occupied a paleovalley incised into the coastal plain during the last glacio-eustatic highstand. The underlying sequences are deformed into

    To achieve rapid incremental extraction of database, an algorithm which is blended MD5 in HASH linear scan-ning to obtain increment is put forward based on analyzing the traditional incremental extraction. Each record in database can be seen as a character string and it can be generated into hash table as duplicate record, which is explored in hash table through traditional record to obtain increment and decrease frequency of comparison. Meanwhile, the fingerprint of each record can be generated with using MD5 algorithm, which reduces the length of character string in every HASH algorithm and comparison and improves efficiency. This algorithm is applicably tested in ORACLE database and the result shows that it is improved on calculative efficiency at a large extent compared with traditional algorithm.%为了实现数据库中的快速增量提取,在剖析传统的增量提取方法上,提出了一种融入MD5的HASH线性扫描来获取增量的算法。数据库中的每条记录都可视为一个字符串,利用HASH算法生成备份记录的散列表,通过原始记录去散列表中探测来达到线性扫描就能获取增量的目的,减少了比对次数;同时利用MD5算法生成每条记录的“指纹”,降低了每次HASH运算和比对的字符串长度,提高了效率。对所提出算法在ORACLE数据库上进行了应用测试,结果表明该算法效率较传统方法有很大提高。

    Full Text Available Marek’s disease (MD is a lymphoproliferative disease induced by Marek’s disease virus (MDV infection. With the less efficacy of vaccine in MD prevention, genetically selected MD-resistant chicken becomes more and more important in MD control. To elucidate the mechanism of MD-resistance, lots of researches were focused on the different genetic differences between the resistant and susceptible chickens. However, less is known about the epigenetic features. By using pyrosequencing, the promoter methylations of 18 candidate genes in MD-resistant (L63 and –susceptible (L72 chicken were examined, we found that most of the genes have higher methylation level in L72. MDV infection changed the expressions of all three methyltransferases (DNMT1, DNMT3a and DNMT3b, while the up-regulation of DNMT1 was only shown in L72 and down-regulation of DNMT3b only in L63 at 21dpi. Interestingly, a dynamic change of promoter methylation was observed in most of the genes in both lines during MDV life cycle. Seven genes, including HDAC9, GH, STAT1, CIITA, FABP3, LATS2 and H2Ac, showed different methylation behavior between L63 and L72. In summary, the findings from this study suggested that DNA methylation heterogeneity exists in MD-resistance and –susceptibility chicken, and MDV infection also induces differential methylation alterations, both indicating epigenetic factor may involve in MD.

    Objective]Cloning of the key light responsive bZIP (Basic-leucine zipper) transcription factors fromMalus domestica Borkh, gene expression and protein interaction analysis, which were determined to identify the function and molecular mechanism ofMdHY5.[Method]First, semi-quantitative primers used for detecting expression levels were designed from the apple in order to identify the light-responsivebZIP genes. Differentially screened and identified a light responsive gene named as MdHY5 based on comparative analysis of homologous. Subsequently, the primers were designed to clone theMdHY5 gene. Phylogenetic relationship including the MdHY5 protein withArabidopsis bZIP proteins was analyzed using MEGA5 and the multiple alignment of bZIP domain was constructed, while the conserved protein domain was predicted, spatio expression analysis was made to detect the MdHY5 in different organs. The expression ofMdHY5 in response to various light qualities was detected by semi-quantitative RT-PCR based on promoter prediction analysis, combined with theArabidopsis microarray database. Finally,MdHY5 gene was inserted into the prokaryotic vectorpGEX-4T-1, and IPTG was used to induce the fusion protein expression inE.coliBL21. Then the fusion protein was purified and detected by Western blot. The interaction between MdHY5 and MdCOP1 was detected by pull down assay.[Result]A bZIP transcription factor was isolated in apple through the light response analysis. Phylogenetic relationship showed that MdHY5 is a homolog ofArabidopsis AtHY5. This gene is located on chromosome 12 of apple genome, with the gene number MDP0000586302,MdHY5 gene contains four exons and three introns in genome structure, which is similar to its homolog. The length of the cDNA is 1 112 bp, with 214 bp in the 5′ untranslated region, 403 bp in 3′ untranslated region, and 495 bp of open reading frame, which encode a 164 amino acid residues. MdHY5 contains a leucine zipper structure typical (bZIP domain) in the C

    Marek's disease virus (MDV) GX0101, which is a field strain with a naturally occurring insertion of the reticuloendotheliosis virus (REV) long terminal repeat (LTR) fragment, shows distinct biological activities. Deletion of the meq gene in GX0101 contributes to its complete loss of pathogenicity and oncogenicity in SPF chickens, but this virus has a kanamycin resistance gene (kan(r)) residual at the site of meq gene. In the present study, the kan(r) was knocked out and a meq-null virus with a good replicative ability termed SC9-1 was selected. In vivo studies showed that SC9-1 had no pathogenicity or tumorigenicity to chickens. There were no obvious impacts on chicken weight, immune organ index or antibody levels induced by avian influenza virus (AIV)/newcastle disease virus (NDV) inactivated vaccines compared with the control group. The SC9-1 virus provided superior protection than CVI988/Rispens vaccine in both SPF chickens and Hy-line brown chickens when challenged with a very virulent MDV (rMd5 strain). There was no obvious change in SC9-1 protection against MDV rMd5 in SPF chickens after 20 passages in chicken embryonic fibroblast cells (CEFs). In conclusion, SC9-1 is a safe and effective vaccine candidate for the prevention of Marek's disease.

  14. Perceived and actual environmental benefits of the Los Angeles urban forest

    Science.gov (United States)

    Pataki, D. E.; McCarthy, H. R.

    2011-12-01

    There has been a widespread movement to plant more trees and increase canopy cover in cities throughout the United States, in order to enhance ecosystem services provided by urban forests. The city of Los Angeles has been engaged in a widespread tree planting program with the goal of increasing tree cover, particularly in low income neighborhoods. However, the Los Angeles urban forest is almost entirely non-native, located predominately in former semi-arid shrublands and grasslands. We used multiple approaches to evaluate environmental costs and benefits of urban trees in Los Angeles, both as they are perceived by local residents, as well as actual physical impacts of urban tree processes on the environment. We conducted an internet survey of attitudes and preferences for specific tree functional types, ecosystem services, and potential costs. We also directly measured urban forest structure and function including species and functional biodiversity, transpiration, basal area increments, hydraulic architecture, and leaf gas exchange. We translated these processes into categories of ecosystem services and costs such as water use, latent heat fluxes, water use efficiency, growth rates, sensitivity to drought stress, and aesthetic traits (flowering, fruiting, etc.). We found that provision of shade by urban trees is highly valued by local residents, and in fact, the urban forest has a significant impact on surface temperatures. Aesthetics benefits are also commonly cited as desirable traits. Although aesthetic and other cultural ecosystem services are difficult to quantify, we found spatial patterns in aesthetic traits influenced by neighborhood socioeconomic variables. Local residents seemed less concerned about the water use of irrigated urban trees, but we found significant rates of transpiration in urban trees and forest plots depending on species that may be important in the local hydrologic budget, which is increasingly constrained by water shortages. There was

    We use ambient measurements to apportion the relative contributions of different source sectors to the methane (CH4) emissions budget of a U.S. megacity. This approach uses ambient measurements of methane and C2-C5 alkanes (ethane through pentanes) and includes source composition information to distinguish between methane emitted from landfills and feedlots, wastewater treatment plants, tailpipe emissions, leaks of dry natural gas in pipelines and/or local seeps, and leaks of locally produced (unprocessed) natural gas. Source composition information can be taken from existing tabulations or developed by direct sampling of emissions using a mobile platform. By including C2-C5 alkane information, a linear combination of these source signatures can be found to match the observed atmospheric enhancement ratios to determine relative emissions strengths. We apply this technique to apportion CH4 emissions in Los Angeles, CA (L.A.) using data from the CalNex field project in 2010. Our analysis of L.A. atmospheric data shows the two largest CH4 sources in the city are emissions of gas from pipelines and/or from geologic seeps (47%), and emissions from landfills (40%). Local oil and gas production is a relatively minor source of CH4, contributing 8% of total CH4 emissions in L.A. Absolute CH4 emissions rates are derived by multiplying the observed CH4/CO enhancement ratio by State of California inventory values for carbon monoxide (CO) emissions in Los Angeles. Apportioning this total suggests that emissions from the combined natural and anthropogenic gas sources account for the differences between top-down and bottom-up CH4 estimates previously published for Los Angeles. Further, total CH4 emission attributed in our analysis to local gas extraction represents 17% of local production. While a derived leak rate of 17% of local production may seem unrealistically high, it is qualitatively consistent with the 12% reported in a recent state inventory survey of the L.A. oil and

    Full Text Available Biliary atresia (BA is the leading cause of pediatric end-stage liver disease in the United States. Education of parents in the perinatal period with stool cards depicting acholic and normal stools has been associated with improved time-to-diagnosis and survival in BA. PoopMD is a mobile application that utilizes a smartphone's camera and color recognition software to analyze an infant's stool and determine if additional follow-up is indicated. PoopMD was developed using custom HTML5/CSS3 and wrapped to work on iOS and Android platforms. In order to define the gold standard regarding stool color, seven pediatricians were asked to review 45 photographs of infant stool and rate them as acholic, normal, or indeterminate. Samples for which 6+ pediatricians demonstrated agreement defined the gold standard, and only these samples were included in the analysis. Accuracy of PoopMD was assessed using an iPhone 5s with incandescent lighting. Variability in analysis of stool photographs as acholic versus normal with intermediate rating weighted as 50% agreement (kappa was compared between three laypeople and one expert user. Variability in output was also assessed between an iPhone 5s and a Samsung Galaxy S4, as well as between incandescent lighting and compact fluorescent lighting. Six-plus pediatricians agreed on 27 normal and 7 acholic photographs; no photographs were defined as indeterminate. The sensitivity was 7/7 (100%. The specificity was 24/27 (89% with 3/27 labeled as indeterminate; no photos of normal stool were labeled as acholic. The Laplace-smoothed positive likelihood ratio was 6.44 (95% CI 2.52 to 16.48 and the negative likelihood ratio was 0.13 (95% CI 0.02 to 0.83. kappauser was 0.68, kappaphone was 0.88, and kappalight was 0.81. Therefore, in this pilot study, PoopMD accurately differentiates acholic from normal color with substantial agreement across users, and almost perfect agreement across two popular smartphones and ambient light

    Increasing inventory of tall buildings in the United States and elsewhere may be subjected to motions generated by near and far seismic sources that cause long-period effects. Multiple sets of records that exhibited such effects were retrieved from tall buildings in Tokyo and Osaka ~ 350 km and 770 km from the epicenter of the 2011 Tohoku earthquake. In California, very few tall buildings have been instrumented. An instrumented 52-story building in downtown Los Angeles recorded seven local and distant earthquakes. Spectral and system identification methods exhibit significant low frequencies of interest (~0.17 Hz, 0.56 Hz and 1.05 Hz). These frequencies compare well with those computed by transfer functions; however, small variations are observed between the significant low frequencies for each of the seven earthquakes. The torsional and translational frequencies are very close and are coupled. Beating effect is observed in at least two of the seven earthquake data.

    1994-05-01

    Full Text Available Recent American science fiction (which commercially dominates world science fiction incorporates two schools of thought, ‘cyberpunk' and ‘hard SF’. which may be read to embody, respectively, radical/liberal and patriotic/ conservative propaganda. This article, after attempting to define aspects of these schools, examines Queen of Angels by Greg Bear (who before producing that text had been a proponent of hard SF. This text is shown to have strong elements of cyberpunk (possibly, to judge by one critical review, appealing to a cyberpunk audience but to have transformed and inverted the radical and liberal themes of cyberpunk into conservative themes. The text thus illuminates philosophical and technical differences between the schools. It is suggested that the imagery of cyberpunk, and perhaps that of science fiction in general, is liable to such reversals of ideological significance.

  1. Divergence of Temperature and Wind Signals in Tree Rings at Port Angeles, WA

    Hamilton, W. L.

    2007-12-01

    At Port Angeles, WA some divergence of tree response to temperature may be explained by previously reported response of trees to wind. Near a weather station there two intermixed populations of low elevation Douglas-fir were found, of which roughly half showed positive response of annual ring width eccentricity to integrated, instrumentally measured hourly wind velocity over the same time interval and in the same direction. The other half responded negatively to the same wind along the same measurement transect azimuth. A similar result was obtained for wind when using ring width data from the downwind sides of the trees, where much of the wind signal was retained by modulation of early wood growth. This is similar to the Wilmking et al. description of divergent temperature response of transect mean ring width in high elevation trees on the Alaska Brooks Range; where a third showed positive, a third showed negative and a third had insignificant correlation with temperature. Eccentricity in Port Angeles northeast-southwest and southeast-northwest transects shows significant divergence of both wind and wind-associated temperature response from 1997 to 2001. Alternating power and lag of wind and temperature correlations with eccentricity at certain azimuths suggests that wind and temperature may operate interdependently in affecting eccentric growth. Response power and sign were highly dependent on the tree, transect azimuth and lag. Trees responded with wind azimuth resolution close to 10°, suggesting that accuracy and precision of sampling azimuth are important. Response power on most transects in most trees was usually higher at zero response lag. Eccentricity response to temperature and wind was usually of opposite sign. Northeast and southeast transect mean width showed weak, temperature-driven divergence at one-year lag. Analysis is underway back to 1982. At Port Angeles warmer winds from the Strait of Juan de Fuca flowed from the northern sector. No clear time

    2010-01-01

    This case study of recent efforts to deconcentrate poverty within the Skid Row area of Los Angeles examines processes of "weak-center" gentrification as it applies to a "service dependent ghetto," thus filling two key gaps in prior scholarship. We document the collaboration between the government, business and development interests, and certain non-profit agencies in this process and identify two key mechanisms of poverty deconcentration: housing/service displacement and the criminalization of low income residents. Following Harvey, we argue that these efforts are driven by pressures to find a "spatial fix" for capital accumulation through Downtown redevelopment. This process has been hotly contested, however, illustrating the strength of counter-pressures to gentrification/poverty deconcentration within "weak-center" urban areas.

    We investigated the phenology of adult angel lichen moths (Cisthene angelus) along a 364-km long segment of the Colorado River in Grand Canyon, Arizona, USA, using a unique data set of 2,437 light-trap samples collected by citizen scientists. We found that adults of C. angelus were bivoltine from 2012 to 2014. We quantified plasticity in wing lengths and sex ratios among the two generations and across a 545-m elevation gradient. We found that abundance, but not wing length, increased at lower elevations and that the two generations differed in size and sex distributions. Our results shed light on the life history and morphology of a common, but poorly known, species of moth endemic to the southwestern United States and Mexico.

    1988-01-01

    The I-Xe systems of six Allende inclusions (five Eggs and the Pink Angel) appear to have been altered by nonnebular secondary processes. Evidence for this includes temperature-ordered variations in the initial I isotopic composition within several objects (with older apparent I-Xe ages associated with higher extraction temperatures) and the absence of primitive I-Xe ages. The span of apparent ages seen in Allende objects (10 Myr or more) is probably too long to reflect any nebular process, so at least some alteration probably occurred ont the parent body. The range in initial (Pu-244)/(U-238) ratios for the Eggs (0.003-0.014) includes the current best estimates of the bulk solar system value (0.004-0.007). For Egg 3, the Pu/U ratio varies by a factor of two between extractions, probably the result of fractionation of Pu from U among different phases.

    The Burning Index (BI) is commonly used as a predictor of wildfire activity. An examination of data on the BI and wildfires in Los Angeles County, California, from January 1976 to December 2000 reveals that although the BI is positively associated with wildfire occurrence, its predictive value is quite limited. Wind speed alone has a higher correlation with burn area than BI, for instance, and a simple alternative point process model using wind speed, relative humidity, precipitation and temperature well outperforms the BI in terms of predictive power. The BI is generally far too high in winter and too low in fall, and may exaggerate the impact of individual variables such as wind speed or temperature during times when other variables, such as precipitation or relative humidity, render the environment ill suited for wildfires. ??

    2011-12-01

    Urban metabolism is a powerful method for describing resource flows into cities and the waste streams produced as a result of resource use. To date these flows have rarely been geospatially correlated to reveal who uses what type of energy where and the concomitant waste streams. Thus there is little ability to understand energy use in urban areas. Additionally, the social and ecological footprint of the flows have not been drawn and explained. We are developing an expanded and integrated urban metabolism analysis for Los Angeles County, attempting to integrate socio-demographic and geospatial grounding of resource flows and sinks, as well as life cycle, cradle to grave information. This presentation will focus on the reasons for this approach and methodological innovations and challenges.

    High-resolution seismic reflection profiles image discrete folds in the shallow subsurface (Puente Hills blind-thrust fault system, Los Angeles basin, California. The profiles demonstrate late Quaternary activity at the fault tip, precisely locate the axial surfaces of folds within the upper 100 m, and constrain the geometry and kinematics of recent folding. The Santa Fe Springs segment of the Puente Hills fault zone shows an upward-narrowing kink band with an active anticlinal axial surface, consistent with fault-bend folding above an active thrust ramp. The Coyote Hills segment shows an active synclinal axial surface that coincides with the base of a 9-m-high scarp, consistent with tip-line folding or the presence of a backthrust. The seismic profiles pinpoint targets for future geologic work to constrain slip rates and ages of past events on this important fault system.

    2016-09-01

    A velocity (Vs) and structure model is derived for the Los Angeles Basin, California based on ambient-noise surface wave and receiver-function analysis, using data from a low-cost, short-duration, dense broad-band survey (LASSIE) deployed across the basin. The shear wave velocities show lateral variations at the Compton-Los Alamitos and the Whittier Faults. The basement beneath the Puente Hills-San Gabriel Valley shows an unusually high velocity (˜4.0 km s-1) and indicates the presence of schist. The structure of the model shows that the basin is a maximum of 8 km deep along the profile and that the Moho rises to a depth of 17 km under the basin. The basin has a stretch factor of 2.6 in the centre grading to 1.3 at the edges and is in approximate isostatic equilibrium.

  10. In the postmodern mirror: intertextuality in Angels and Insects by Antonia Susan Byatt

    Directory of Open Access Journals (Sweden)

    Buda Agata

    2015-05-01

    Full Text Available The aim of the paper is to analyse the novel Angels and Insects by Antonia Susan Byatt in terms of intertextual references. The author’s assumptions are based on the categorisation by Ryszard Nycz, who distinguishes three major types of intertexts: text versus text, text versus literary genre and text versus mimesis. Byatt uses intertextuality mainly to comment on the role of nature in the world, as well as to enhance the importance of human relationship with nature. Moreover, the writer moves towards literary criticism, discussing poems by famous artists, such as Alfred Tennyson or John Milton. In this way, the novel by Byatt is also an example of metafiction. All the narration techniques used by the English writer make the novel a typically postmodern work of art.

    In order to observe the role of calcium ion in apoptosis of MD cancer cells induced by arsenic trioxide, inhibition percentage was detected by MTT assay;morphology changes were examined by fluorescence microscope;apoptosis was examined by DNA Ladder;[Ca2+]i was investigated by spectrofluorimeter in vitro on MDCC-MSB1 cells. The results showed that As2O3 inhibited the proliferation of MDCC-MSB1 cells in concentration dependent manner (P<0.05 or P<0.01);typical apoptosis character was observed by fluorescence microscope;DNA Ladder was observed;the [Ca2+]i was elevated significantly after the treatment of As203 (P<0.05 or P<0.01) and showed a dose-dependent manner. It is concluded that the calcium may play an important role in apoptosis of MD cancer cells induced by arsenic trioxide.

    2017-01-01

    The aim of the MD was to measure the coupled-bunch stability from all HOM impedances, with a reduced longitudinal emittance in order to explore the HL-LHC conditions. The acceleration ramp was performed with the nominal beams of 2016, but a reduced target bunch length and RF voltage. With this reduced emittance, the beam remained close but above the single-bunch stability threshold. No coupled-bunch oscillations were observed, so we can conclude that the stability threshold for coupled-bunch instability is not lower than the single-bunch threshold. An interesting observation in the MD was the long-lasting injection oscillations, whose traces can still be seen at arrival to flat top; in agreement with observations in earlier MDs. The measurements took place between 28th October 20:00 and 29th October 05:10.

    During MD1751, it was observed that both a full single beam and 964 non-colliding bunches in Beam 1 (B1) and Beam 2 (B2) were both stable at the End of Squeeze (EOS) for 0A in the Landau Octupoles. At ß* = 40cm there is also a significant Q" arising from the lattice, as well as uncorrected non-linearities in the Insertion Regions (IRs). Each of these effects could be capable of fully stabilising the beam. This MD made first use of a Q" knob through variation of the Main Sextupoles (MS) by stabilising a single bunch at Flat Top, before showing at EOS that the non-linearities were the main contributors to the beam stability.

    Photoionization models obtained with numerical codes are widely used to study the physics of the interstellar medium (Planetary Nebulae, H II regions, etc). Grid of models are performed to understand what are the effects of the different parameters used to describe the regions on the observables (mainly emission line intensities). Most of the time, only a small part of the computed results of such grids are published, and they are sometimes hard to obtain in a user-friendly format. We present here the Mexican Million Models dataBase (3MdB), an effort of resolving both of these issues in the form of a database of photoionization models, easily accessible throught the MySQL protocol, and containing a lot of usefull outputs from the models, such as the intensities of 178 emission lines, the ionic fractions of all the ions, etc. Some examples of the use of the 3MdB are also presented.

    We study scalar field theories on M^{D-1} \\otimes S^1, which allow to impose twisted boundary conditions for the S^1 direction, in detail and report several interesting properties overlooked so far. One of characteristic features is the appearance of critical radii of the circle S^1. A phase transition can occur at the classical level or can be caused by quantum effects. Radiative corrections can restore broken symmetries or can break symmetries for small radius. A surprising feature is that the translational invariance for the S^1 direction can spontaneously be broken. A particular class of coordinate-dependent vacuum configurations is clarified and the O(N) \\phi^4 model on M^{D-1}\\otimes S^1 is extensively studied, as an illustrative example.

    Full Text Available Abstract Purpose of the article Mapping and comparing the investors‘ environment in the USA and in the Czech Republic. To focus on characteristics of Business Angels in both markets, the Czech Republic and the USA. Methodology/methods The used research methods are adjusted to the aim of the article. To make an overview of the situation in the Czech Republic, all available sources regarding investors themselves, and investing into new companies were analyzed. A case study was used as a method of this paper, in order to describe the investors and find out their similarities and dissimilarities. The case study also enabled to find out the features in the frame of the investors‘ spectrum. The research was conducted with 50 investors. In order to provide the triangulation, the author chose three methods of data collection. More specifically, questionnaire, archival data (accelerator documents, data on the internet and interview. Scientific aim The aim of this paper is to map the investors characteristics in the Czech Republic and the USA. Moreover, to compare both markets in the regard of investors and investing environment. Findings and conclusions Based on outcomes of used methods, the following facts were found out. Business Angels (BA in the USA tends to be older, with more experience and higher education. Investing is considered as their full-time job and based on that fact their portfolio is wider. Their source of motivation is knowledge transfer to young entrepreneurs (for 90% of investors. In the Czech Republic, there is lack of collaboration among BA, which leads to less investments. The solution might be perceived in establishing the syndicates of BA. Moreover, it is necessary to present good quality projects to BA, consequently the young entrepreneurs need more initiatives and opportunities to gain the required knowledge and practice

    Analysis of in situ airborne measurements from the CalNex 2010 field experiment (Research at the Nexus of Air Quality and Climate Change) show that ozone in the boundary layer over Southern California was increased by downward mixing of air from the free troposphere (FT). The chemical composition, origin, and transport of air upwind and over Los Angeles, California, were studied using measurements of carbon monoxide (CO), ozone, reactive nitrogen species, and meteorological parameters from the National Oceanic and Atmospheric Administration WP-3D aircraft on 18 research flights in California in May and June 2010. On six flights, multiple vertical profiles from 0.2-3.5 km above ground level were conducted throughout the Los Angeles (LA) basin and over the Pacific Ocean. Gas phase compounds measured in 32 vertical profiles are used to characterize air masses in the FT over the LA basin, with the aim of determining the source of increased ozone observed above the planetary boundary layer (PBL). Four primary air mass influences were observed regularly in the FT between approximately 1 and 3.5 km altitude: upper tropospheric air, long-range transport of emissions, aged regional emissions, and marine air. The first three air mass types accounted for 89% of the FT observations. Ozone averaged 71 ppbv in air influenced by the upper troposphere, 69 ppbv in air containing emissions transported long distances, and 65 ppbv in air with aged regional emissions. Correlations between ozone and CO, and ozone and nitric acid, demonstrate entrainment of ozone from the FT into the LA PBL. Downward transport of ozone-rich air from the FT into the PBL contributes to the ozone burden at the surface in this region and makes compliance with air quality standards challenging.

    We reported previously that increases in ambient air pollution in the Los Angeles basin increased the risk of low weight and premature birth. However, ambient concentrations measured at monitoring stations may not take into account differential exposure to pollutants found in elevated concentrations near heavy-traffic roadways. Therefore, we used an epidemiologic case-control study design to examine whether residential proximity to heavy-traffic roadways influenced the occurrence of low birth weight (LBW) and/or preterm birth in Los Angeles County between 1994 and 1996. We mapped subject home locations at birth and estimated exposure to traffic-related air pollution using a distance-weighted traffic density (DWTD) measure. This measure takes into account residential proximity to and level of traffic on roadways surrounding homes. We calculated odds ratios (ORs) and risk ratios (RRs) for being LBW and/or preterm per quintile of DWTD. The clearest exposure-response pattern was observed for preterm birth, with an RR of 1.08 [95% confidence interval (CI), 1.01-1.15] for infants in the highest DWTD quintile. Although higher risks were observed for LBW infants, exposure-response relations were less consistent. Examining the influence of season, we found elevated risks primarily for women whose third trimester fell during fall/winter months (OR(term LBW) = 1.39; 95% CI, 1.16-1.67; OR(preterm and LBW) = 1.24; 95% CI = 1.03-1.48; RR(all preterm) = 1.15; 95% CI, 1.05-1.26), and exposure-response relations were stronger for all outcomes. This result is consistent with elevated pollution in proximity to sources during more stagnant air conditions present in winter months. Our previous research and these latest results suggest exposure to traffic-related pollutants may be important.

    Urban green space provides a suite of valuable ecosystem services. In semiarid systems, like Los Angeles, trees rely primarily on irrigation water for transpiration. Managers may need to reduce irrigation associated with urban trees given climate change, urban expansion, and the steady decrease in available freshwater. While leaf and whole plant water relations have been extensively studied, we are only now gaining a detailed understanding of diverse leaf anatomical designs, and their use for predicting physiology and water use at landscape scale. For 50 diverse urban species, we quantified leaf anatomical and physiological traits important to tree drought tolerance and water use efficiency including turgor loss point, vein architecture, cellular anatomy, leaf mass per unit area, and petiole and leaf dimensions. We hypothesized detailed relationships to develop models relating leaf functional traits to tree water relations. These models provide key insights regarding the role of anatomical designs in leaf stress tolerance and water use efficiency. Additionally we predicted how traits measured at the leaf level would scale with existing data for individuals at the whole plant level. We tested our predictions by determining correlations between leaf level anatomical traits and drought tolerance. Additionally, we determined correlations between functional traits, physiology and water use, and the climate of origin for the urban species. Leaf level measurements will be valuable for rapid estimation of more difficult to measure whole plant water relations traits important at the landscape scale. The Los Angeles urban ecosystem can serve as a model for other semiarid system and provide more informed system wide water conservation strategies.

  2. Evaluating the Impact of Conservation Measures on Urban Water Fluxes in Los Angeles, California

    California is experiencing one of the most severe droughts on record. In response, the State Water Resources Control Board adopted emergency regulations in May, implementing a mandatory 25% statewide reduction in potable urban water use. Prior to this, the Los Angeles Department of Water and Power had implemented mandatory restrictions and a pricing increase in 2009 and 2010, respectively to encourage reduced consumption. Understanding where conservation measures are having the greatest impact and how it is affecting water fluxes throughout the basin is critical, especially when considering the push for increased reliance on local water resources. Los Angeles is selected as the study area due to its high degree of urbanization, while the Ballona Creek watershed is used for runoff analysis due to the lack of dams and wastewater treatment plants altering flow in the channel. Utilizing a combination of runoff gages, groundwater monitoring well data, consumption data, and hydrologic models, we aim to evaluate how hydrologic processes have been influenced by water conservation measures. The work focuses on how changes in outdoor water use have influenced discharge patterns and groundwater recharge since most of the water conservation efforts have been focused on decreasing landscape irrigation. Previous work has shown that outdoor irrigation rates have decreased after the implementation of conservation measures, causing a decrease in vegetation greenness across the city. Runoff has also significantly decreased, especially dry season discharge. Further work is also being conducted to evaluate changes to evapotranspiration, using a combination of NLDAS model results and CIMIS reference ET data, as well as groundwater and recharge, utilizing a Bayesian Hierarchical model to fill missing groundwater monitoring well data. Results provide improved understanding of response to, and impacts of, conservation measures which ultimately allow for better water resources management

  4. An Efficient Hybrid DSMC/MD Algorithm for Accurate Modeling of Micro Gas Flows

    2013-01-01

    Aiming at simulating micro gas flows with accurate boundary conditions, an efficient hybrid algorithmis developed by combining themolecular dynamics (MD) method with the direct simulationMonte Carlo (DSMC)method. The efficiency comes from the fact that theMD method is applied only within the gas-wall interaction layer, characterized by the cut-off distance of the gas-solid interaction potential, to resolve accurately the gas-wall interaction process, while the DSMC method is employed in the remaining portion of the flow field to efficiently simulate rarefied gas transport outside the gas-wall interaction layer. A unique feature about the present scheme is that the coupling between the two methods is realized by matching the molecular velocity distribution function at the DSMC/MD interface, hence there is no need for one-toone mapping between a MD gas molecule and a DSMC simulation particle. Further improvement in efficiency is achieved by taking advantage of gas rarefaction inside the gas-wall interaction layer and by employing the "smart-wall model" proposed by Barisik et al. The developed hybrid algorithm is validated on two classical benchmarks namely 1-D Fourier thermal problem and Couette shear flow problem. Both the accuracy and efficiency of the hybrid algorithm are discussed. As an application, the hybrid algorithm is employed to simulate thermal transpiration coefficient in the free-molecule regime for a system with atomically smooth surface. Result is utilized to validate the coefficients calculated from the pure DSMC simulation with Maxwell and Cercignani-Lampis gas-wall interaction models. ©c 2014 Global-Science Press.

  12. Hybrid Pressure Retarded Osmosis−Membrane Distillation (PRO−MD) Process for Osmotic Power and Clean Water Generation

    KAUST Repository

    Han, Gang

    2015-05-20

    A novel pressure retarded osmosis−membrane distillation (PRO−MD) hybrid process has been experimentally conceived for sustainable production of renewable osmotic power and clean water from various waters. The proposed PRO−MD system may possess unique advantages of high water recovery rate, huge osmotic power generation, well controlled membrane fouling, and minimal environmental impacts. Experimental results show that the PRO−MD hybrid process is promising that not only can harvest osmotic energy from freshwater but also from wastewater. When employing a 2 M NaCl MD concentrate as the draw solution, ultrahigh power densities of 31.0 W/m2 and 9.3 W/m2 have been demonstrated by the PRO subsystem using deionized water and real wastewater brine as the feeds, respectively. Simultaneously, high purity potable water with a flux of 32.5−63.1 L/(m2.h) can be produced by the MD subsystem at 40−60 °C without any detrimental effects of fouling. The energy consumption in the MD subsystem might be further reduced by applying a heat exchanger in the hybrid system and using low-grade heat or solar energy to heat up the feed solution. The newly developed PRO−MD hybrid process would provide insightful guidelines for the exploration of alternative green technologies for renewable osmotic energy and clean water production.

  13. Mimicking titration experiments with MD simulations: A protocol for the investigation of pH-dependent effects on proteins

    Protein structure and function are highly dependent on the environmental pH. However, the temporal or spatial resolution of experimental approaches hampers direct observation of pH-induced conformational changes at the atomic level. Molecular dynamics (MD) simulation strategies (e.g. constant pH MD) have been developed to bridge this gap. However, one frequent problem is the sampling of unrealistic conformations, which may also lead to poor pKa predictions. To address this problem, we have developed and benchmarked the pH-titration MD (pHtMD) approach, which is inspired by wet-lab titration experiments. We give several examples how the pHtMD protocol can be applied for pKa calculation including peptide systems, Staphylococcus nuclease (SNase), and the chaperone HdeA. For HdeA, pHtMD is also capable of monitoring pH-dependent dimer dissociation in accordance with experiments. We conclude that pHtMD represents a versatile tool for pKa value calculation and simulation of pH-dependent effects in proteins.

A new computational system for the accurate and fast simulation and 3D/VR visualization of nanostructures is presented here, using the open-source molecular dynamics (MD) computer program LAMMPS. This alternative computational method uses modern graphics processors, NVIDIA CUDA technology and specialized scientific codes to overcome processing speed barriers common to traditional computing methods. In conjunction with a virtual reality system used to model materials, this enhancement allows the addition of accelerated MD simulation capability. The motivation is to provide a novel research environment which simultaneously allows visualization, simulation, modeling and analysis. The research goal is to investigate the structure and properties of inorganic nanostructures (e.g., silica glass nanosprings) under different conditions using this innovative computational system. The work presented outlines a description of the 3D/VR Visualization System and basic components, an overview of important considerations such as the physical environment, details on the setup and use of the novel system, a general procedure for the accelerated MD enhancement, technical information, and relevant remarks. The impact of this work is the creation of a unique computational system combining nanoscale materials simulation, visualization and interactivity in a virtual environment, which is both a research and teaching instrument at UC Merced.

  15. Cryptanalysis of Two MD5-Based Authentication Protocols: APOP and NMAC

    Many hash-based authentication protocols have been proposed, and proven secure assuming that underlying hash functions are secure. On the other hand, if a hash function compromises, the security of authentication protocols based on this hash function becomes unclear. Therefore, it is significantly important to verify the security of hash-based protocols when a hash function is broken. In this paper, we will re-evaluate the security of two MD5-based authentication protocols based on a fact that MD5 cannot satisfy a required fundamental property named collision resistance. The target protocols are APOP (Authenticated Post Office Protocol) and NMAC (Nested Message Authentication Code), since they or their variants are widely used in real world. For security evaluation of APOP, we will propose a modified password recovery attack procedure, which is twice as fast as previous attacks. Moreover, our attack is more realistic, as the probability of being detected is lower than that of previous attacks. For security evaluation of MD5-based NMAC, we will propose a new key-recovery attack procedure, which has a complexity lower than that of previous attack. The complexity of our attack is 276, while that of previous attack is 2100.**Moreover, our attack has another interesting point. NMAC has two keys: the inner key and the outer key. Our attack can recover the outer key partially without the knowledge of the inner key.

    We present two topics, an analytical model and moelrcular dynamic (MD) simulations of the Richtmyer-Meshokov instability (RMI). We have developled a selfconsistent analytical model that describes a nonlinear evolution of a vortex sheet in the two-dimensional RMI. The model consists of two kinematic boundary conditions, a modified Birkhoff-Rott equation and an equation for time evolution of circulation at the interface with a finite Atwood number. It is shown that the created vortcity on the interface has strong inhomogeneity, that causes locally streching and compression of the sheet. We discuss the dependence of the Atwood number on the nonlinear dynamics of the sheet. MD approache has been applied for converging shocks and RMI in a dense Lennard-Jones fluid in cylindrical geometry. MD method has fundamental advantages over hydrodymanic simulations such as no limitation of resolution in turbulent state. The appearance of Mach stems in the rippled shocks and turbulent mixing in RMI have been observed when the reflected shock passes through the unstable surface again. We discuss the mode number and Mach number dependence on the mixing.

    Metatranscriptomic differential RNA-Seq (mdRNA-Seq) identifies the suite of active transcriptional start sites at single-nucleotide resolution through enrichment of primary transcript 5′ ends. Here we analyzed the microbial community at 45 m depth at Station A in the northern Gulf of Aqaba, Red Sea, during 500 m deep mixing in February 2012 using mdRNA-Seq and a parallel classical RNA-Seq approach. We identified promoters active in situ for five different pico-planktonic genera (the SAR11 clade of Alphaproteobacteria, Synechococcus of Cyanobacteria, Euryarchaeota, Thaumarchaeota, and Micromonas as an example for picoeukaryotic algae), showing the applicability of this approach to highly diverse microbial communities. 16S rDNA quantification revealed that 24% of the analyzed community were group II marine Euryarchaeota in which we identified a highly abundant non-coding RNA, Tan1, and detected very high expression of genes encoding intrinsically disordered proteins, as well as enzymes for the synthesis of specific B vitamins, extracellular peptidases, carbohydrate-active enzymes, and transport systems. These results highlight previously unknown functions of Euryarchaeota with community-wide relevance. The complementation of metatranscriptomic studies with mdRNA-Seq provides substantial additional information regarding transcriptional start sites, promoter activities, and the identification of non-coding RNAs.

    The molecular dynamics (MD) technique based on the ONIOM-XS method, known as the ONIOM-XS MD, has been applied to investigate the solvation structure and dynamics of Na+ in liquid ammonia. Regarding the ONIOM-XS MD results, it is observed that Na+ is able to order the surrounding ammonia molecules to form its specific first and second solvation shells with the average coordination numbers of 5.1 and 11.2, respectively. The first solvation shell of Na+ is rather well-defined, forming a preferred 5-fold coordinated complex with a distorted square pyramidal geometry. In this respect, the most preferential Na+(NH3)5 species could convert back and forth to the lower probability Na+(NH3)6 and Na+(NH3)4 configurations. The second solvation shell of Na+ is detectable, in which a number of ammonia molecules, ranging from 7 to 14, are involved in this layer and they are arranged according to recognizable influence of the ion.

    Antihistamines are frequently used pharmaceuticals that treat the symptoms of allergic reactions. Loratadine (LOR) is an active component of the second generation of selective antihistaminic pharmaceutical usually known as Claritin. Frequent usage of this type of pharmaceuticals imposes the need for understanding their fundamental reactive properties. In this study we have theoretically investigated reactive properties of LOR using both density functional theory (DFT) calculations and molecular dynamics (MD) simulations. DFT study is used for collecting information related to the molecule stability, structure, frontier molecular orbitals, quantum molecular descriptors, charge distribution, molecular electrostatic potential surfaces, charge polarization, and local reactivity properties according to average local ionization energy surfaces. Based on these results, N24 atom of pyridine ring and oxygen atom O1 were identified with nucleophilic nature. In order to collect the information necessary for the proposition of degradation compounds we also calculated bond dissociation energies (BDE) for hydrogen abstraction and single acyclic bonds as well. According to BDE, the oxidation is likely to occur in the piperidine and cycloheptane rings. MD simulations were used in order to understand the interactions with water through radial distribution functions (RDF). Based on RDFs the most important interactions with solvent are determined for carbon atom C5, chlorine atom Cl15, and oxygen atom O1. Collected results based on DFT calculations and MD simulations provided information important for suggestion of possible degradation compounds. Covalent and noncovalent interactions between LOR and (•)OH have also been investigated.

  20. Structural and Dynamic Analysis on IDPs by Modified AWSEM-MD

    Unlike globular proteins, intrinsically disordered proteins (IDPs) lack both secondary and tertiary structures and can play key roles in various biological processes, including transcriptional regulation, molecular recognition and cellular signaling. These functions can be potentially elucidated by structural heterogeneity of IDPs. Because of their flexibility and disordered nature, it has been difficult to investigate IDPs both computationally and experimentally. In particular, it is desirable to develop coarse-grained, yet accurate models of IDPs, such that simulations exploring sufficient conformational ensembles could be carried out within feasible times. To achieve this goal, we modified the associative memory, water mediated, structure and energy model (AWSEM-MD), which is typically used for folding of globular proteins or binding studies. We tested modified AWSEM-MD on several well-studied IDPs and found the transient secondary structure propensity is consistent with NMR experimental results. The rugged free energy landscapes obtained also show structural heterogeneity of these IDPs. Our proposed extension of AWSEM-MD may allow simulating a wider range of IDPs with high accuracy and computational efficiency.

    In this study, an Agrobacteriurn tumefaciens-mediated transformation (ATMT) protocol was successfully developed for the genetic transformation of a taxol-producing fungus, Cladosporium cladosporioides MD2, and the co-cultivation conditions affecting the transformation efficiency were optimized. The optimal transformation conditions were that 1 ml of C. cladosporioides MD2 spore suspension (10(8) spores/ml) was mixed with an equal volume of A. tumefaciens cultures, which contained 400 μl of A. tumefaciens LBA4404 (OD(660) ≈ 0.6) and 600 μl LB medium that were used to make up difference in volume, and the mix cultures were supplemented with 300 μM acetosyringone (AS) and co-cultivated at 26°C and 50 rpm for 48 h. Stable transformants were obtained through analysis of the mitotic stability of inserted T-DNA and the presence of hygromycin resistance gene (hpt II). This study laid a fine groundwork for development of transgenic C. cladosporioides MD2 strains.

    Full Text Available In order to understand the function of mammalians serotonin system, we have to know the anatomical structure, because physiological changes are influenced through the anatomical changes. A number of thalamic nuclei are associated with functions known to be influenced by serotonergic input in brainstem, among them mediodorsal thalamic nucleus has relationship with limbic system and prefrontal cortex. The precise topographical projections of mesencephalic raphe nuclei to the MD nucleus of thalamus were identified in the rat using horseradish peroxidase (HRP retrograde tracing substance. Injection of HRP in MD labeled a large number of neurons in rostral to caudal part of dorsal raphe nucleus. It exhibited a strong number of neurons in ipsilateral part of DR and a few cells in its contralateral part. Numerously labeled cells were also observed ipsilateral in rostral and medial part of MnR (86% and a few cells in it's contralateral part. The present study has provided that the MD innervation by DR is more greater in density than that observed at the MnR. Upon these results and previous study, mesencephalic raphe nuclei are involved in several specific functions of thalamus as limbic system behavioral mechanism. A much more detailed knowledge is needed to show topographic relationships between mesencephalic raphe nuclei and forebrain.

    Tornado code based replication algorithm had the advantages of faster encoding and decoding, and could also recover the original data when some data were missing, but when the algorithm was applied to a dis-tributed storage system, the presence of data would be susceptible to theft, tampering risk. For this reason, several optimization strategies were proposed to improve the replication algorithm based on Tornado code:1 ) an encryption mechanism into replication algorithm was introduced in case of even some data were stolen there would be no worry about information leak. 2)the raw data using the MD5 algorithm to generate digital finger-prints produced a digital fingerprint when retrieving data from a distributed storage system with local digital fin-gerprint comparison, it would be easy to determine whether the data had been tampered with.%基于Tornado码的复制算法具有编解码速度比较快、部分数据丢失时亦能被恢复的优点,但将该算法应用于分布式存储系统时,存在数据易被窃取、篡改的风险。为此,对基于Tornado码的复制算法提出了改进:1)引入加密机制,使数据即使被窃取时也不用担心泄密;2)对原始数据使用MD5算法产生数字指纹,当从分布式存储系统取回数据时,计算数字指纹并与本地的数字指纹对比,就可以判断数据是否被篡改。

    Protein and peptide structure predictions are of paramount importance for understanding their functions, as well as the interactions with other molecules. However, the use of molecular simulation techniques to directly predict the peptide structure from the primary amino acid sequence is always hindered by the rough topology of the conformational space and the limited simulation time scale. We developed here a new strategy, named Multiple Simulated Annealing-Molecular Dynamics (MSA-MD) to identify the native states of a peptide and miniprotein. A cluster of near native structures could be obtained by using the MSA-MD method, which turned out to be significantly more efficient in reaching the native structure compared to continuous MD and conventional SA-MD simulation.

    This study describes a series of air monitoring measurements of particle number (PN), black carbon (BC) and PM2.5 mass concentrations in the vicinity of the Los Angeles International Airport (LAX) (roughly 150 m downwind of the LAX's south runways) as well as on-road measurements of the aforementioned pollutants using a mobile platform on three major freeways (i.e., I-110, I-105, and I-405) during May-July 2016. All measurements were performed in the "impact zone" of LAX with the predominant westerly winds from coast to inland. The overall impact of aircraft emissions from the LAX airport and its facilities in comparison to vehicular emissions from freeways on air quality was evaluated on a local scale (i.e. areas in the vicinity of the airport). PN concentration was, on average, 4.1 ± 1.2 times greater at the LAX site than on the studied freeways. Particle number emission factors for takeoffs and landings were comparable, with average values of 8.69 ×1015 particles/kg fuel and 8.16 ×1015 particles/kg fuel, respectively, and indicated a nearly 4-fold statistically significant reduction in PN emission factors for takeoffs during the past decade. BC emission factors were 0.12 ± 0.02 and 0.11 ± 0.01 g/kg fuel during takeoffs and landings, respectively. Additionally, the mean PM2.5 emission factor values for takeoffs and landings were also comparable, with values of 0.38 ± 0.04 and 0.40 ± 0.05 g/kg fuel, respectively. Within the impact zone of the airport, an area of roughly 100 km2 downwind of the LAX, measurements indicated that the LAX daily contributions to PN, BC, and PM2.5 were approximately 11, 2.5, and 1.4 times greater than those from the three surrounding freeways. These results underscore the significance of the LAX airport as a major source of pollution within its zone of impact comparing to freeway emissions.

  4. Mechanical Analysis of Fault Interaction in the Puente Hills Region, Los Angeles Basin, California

    Griffith, W. A.; Cooke, M.

    2002-12-01

    A three-dimensional model of the Puente Hills thrust system (PHT) and the Whittier fault has been constructed using published cross sections, surface trace maps [Shaw (1999); Shaw and Suppe (1996); Wright (1991)] and products of the Southern California Earthquake Center. This study utilizes boundary element method models to validate the proposed fault geometry of the Puente Hills region via investigating fault interaction. The interaction between PHT and Whittier faults is evaluated within an elastic half-space under horizontal contraction and evidenced by slip rates on faults, strain energy density (SED), and Navier-Coulomb stress (NC) throughout the host rock. Modeled slip rates are compared to paleoseismic estimates to validate the proposed fault configuration while maps of SED and NC highlight regions of high strain in the host rock and likely faulting. Subsequently, the sensitivity of SED and NC distribution to changes in fault geometry illuminate the nature of fault interaction within this complex system of interacting faults. We explore interaction of faults within the PHT region using two sets of models. The first examines slip rates and SED and NC distribution within a local model of the PHT region while the second set incorporates the PHT faults within the context of the Los Angeles basin. Both sets explore the response of the fault system to systematic addition of faults. Adding faults within regions of high SED and NC does not influence slip on neighboring faults; however the addition of fault surfaces in regions of low/moderate SED and NC reduces slip along adjacent faults. The sensitivity of fault slip rates to direction of remote contraction in the Los Angeles Basin is examined with contraction directions of 036, 017, and 006.5 [Bawden (2001), Argus (1999), and Feigl (1993)]. Furthermore, variations on intersection geometry between the PHT and Whittier fault are explored. Portions of the PHT and Whittier faults show reasonable match to available

    Objectives To compare certain preconception health (PCH) behaviors and conditions among US-born (USB) and foreign-born (FB) mothers in Los Angeles County (LAC), regardless of race/ethnicity, and to determine if any identified differences vary among Asian/Pacific Islanders (API’s) and Hispanics. Methods Data are from the 2012 Los Angeles Mommy and Baby (LAMB) study (n=6,252). PCH behaviors included tobacco use, multivitamin use, unintended pregnancy, and contraception use. PCH conditions comprised being overweight/obese, diabetes, asthma, hypertension, gum disease, and anemia. The relationship between nativity and each PCH behavior/ condition was assessed using multivariable logistic regression models. Results USB women were more likely than FB women to smoke (AOR=2.12, 95% CI=1.49–3.00), be overweight/obese (AOR=1.57, 95% CI=1.30–1.90), and have asthma (AOR=2.04, 95% CI=1.35–3.09) prior to pregnancy. They were less likely than FB women to use contraception before pregnancy (AOR=0.59, 95% CI=0.49–0.72). USB Hispanics and API’s were more likely than their FB counterparts to be overweight/obese (AOR=1.57, 95% CI=1.23–2.01 and AOR=2.37, 95% CI=1.58–3.56, respectively) and less likely to use contraception (AOR=0.58, 95% CI=0.45–0.74 and AOR= 0.46, 95% CI=0.30–0.71, respectively). USB Hispanic mothers were more likely than their FB counterparts to smoke (AOR=2.47, 95% CI=1.46–4.17), not take multivitamins (AOR=1.30, 95% CI=1.02–1.66), and have asthma (AOR=2.35, 95% CI=1.32–4.21) before pregnancy. Conclusions US nativity is linked to negative PCH among LAC women, with many of these associations persisting among Hispanics and API’s. As PCH profoundly impacts maternal and child health across the lifecourse, culturally-appropriate interventions that maintain positive behaviors among FB reproductive-aged women and encourage positive behaviors among USB women should be pursued.

    Recent studies have suggested that CH4 emissions in Los Angeles and other large cities may be underestimated. We utilized stable isotopes (13C and D) and radiocarbon (14C) to investigate sources of CH4 in Los Angeles, California. First, we made measurements of δ13C and δD of various CH4 sources in urban areas. Fossil fuel CH4 sources (oil refineries, power plants, traffic, and oil drilling fields) had δ13C values between -45 and -30‰ and dD values between -275 and -100‰, whereas biological CH4 (cows, biofuels, landfills, sewage treatment plants, and cattle feedlots) had δ13C values between -65 and -45‰ and δD values between -350 and -275‰. We made high-altitude observations of CH4 concentration using continuous tunable laser spectroscopy measurements combined with isotope analyses (13C, 14C, and D) of discrete samples to constrain urban CH4 sources. Our data indicate that the dominant source of CH4 in Los Angeles has a δ13C value of approximately -41.5‰ and a δD value between -229 and -208‰. Δ14C of CH4 in urban air samples ranged from +262 to +344‰ (127.1 to 134.9 pMC), depleted with respect to average global background CH4. We conclude that the major source of CH4 in Los Angeles is leakage of fossil fuels, such as from geologic formations, natural gas pipelines, oil refining, and/or power plants. More research is needed to constrain fluxes of CH4 from natural gas distribution and refining, as this flux may increase with greater reliance on natural gas and biogas for energy needs.

  9. Air pollutant transport in a coastal environment—II. Three-dimensional simulations over Los Angeles basin

    Science.gov (United States)

    Lu, Rong; Turco, Richard P.

    The: air quality problems in the Los Angeles basin are related to the local climate. A strong temperature inversion and stagnant synoptic conditions associated with the Pacific high-pressure system favor the generation of severe air pollution episodes. Sea-breezes and mountain-induced flows play an important role: in controlling pollutant transport over the basin. The distributions of pollutants over the basin display complicated three-dimensional patterns, including distinct elevated layers. A three-dimensional meteorological model is used to simulate air flow patterns and pollutant transport in the Los Angeles basin under such conditions. The complex simulated flows are analyzed to explain the origin of the observed pollution layers. Pollutants found in the afternoon mixed layer may be dispersed to three different regions: the high desert to the east and north of the Los Angeles basin; the free troposphere above the temperature inversion; and within the temperature inversion layer itself. Several mechanisms transfer pollution into the inversion layer. Convergence zones in the San Fernando Valley and near Lake Elsinore lift polluted air into the inversion. A coupled sea-bree~eymountain-flow circulation along the southwest flank of the Santa Ana Mts creates pollution layers that extend westward over the coastal plain and offshore. The afternoon pollution layers frequently observed in the western Los Angeles basin are caused by the sea-breeze circulation or the coupled sea-breeze/mountain-flow circulation over the south slope of the San Gabriel Nlts. As the boundary layer stabilizes during the early evening, layers of polluted air are left suspended over the eastern basin. Pollutants trapped in the inversion layer act as a reservoir of poor-quality air for the basin, and may contribute to extreme pollutant concentrations seen after several days of stagnant air.

    The 25 March 1993 ML = 5.7 crustal earthquake near Scotts Mills, Oregon, was the largest earthquake to occur in the Pacific Northwest in over a decade. The mainshock was located at 45.033?? N, 122.586?? W and at a depth of about 15.1 km, based on arrival time data from the short-period Pacific Northwest Seismograph Network. Beginning about 12 h after the mainshock, investigators from the U.S. Geological Survey deployed 22 digital seismographs to record aftershocks. Using data from the temporary and permanent stations, we analyzed a subset of 50 after-shocks with quality locations. Hypocenters of these aftershocks lie on a northwesttrending steeply dipping plane (strike 290 ?? 10??, dipping 60 ?? 5?? to the north-northeast), in agreement with the preferred slip plane of the mainshock focal mechanism solution (strike 294??, dipping 58?? to the north-northeast). The planar structure defined by the aftershock locations may be a southeast continuation of the Mount Angel Fault, a reverse fault identified from both surface and subsurface evidence. The mapped southeast extent of the Mount Angel Fault is located less than 10 km west of the Scotts Mills epicentral region. In addition, the mainshock focal mechanism solution, with a combination of reverse motion and right-lateral strike slip, has a geometry and sense of motion consistent with the Mount Angel Fault. While aftershock focal mechanisms are varied, P axes are consistently oriented in a subhorizontal north-south direction. This earthquake sequence, together with the geological and geophysical evidence for the Mount Angel Fault, suggests a significant crustal earthquake hazard for this region of northwest Oregon.

  12. The Fossil Fueled Metropolis: Los Angeles and the Emergence of Oil-Based Energy in North America, 1865--1930

    Science.gov (United States)

    Cooke, Jason Arthur

    Beginning with coal in the nineteenth century, the mass production and intensive consumption of fossil fuel energy fundamentally changed patterns of urban and industrial development in North America. Focusing on the metropolitan development of Los Angeles, this dissertation examines how the emergence of oil-based capitalism in the first three decades of the twentieth century was sustained and made increasingly resilient through the production of urban and industrial space. In a region where coal was scarce, the development of oil-based energy was predicated on long-term investments into conversion technologies, storage systems and distribution networks that facilitated the efficient and economical flow of liquefied fossil fuel. In this dissertation, I argue that the historical and geographical significance of the Southern California petroleum industry is derived from how its distinctive market expansion in the first three decades of the twentieth century helped establish the dominance of oil-based energy as the primary fuel for transportation in capitalist society. In North America, the origins of oil-based capitalism can be traced to the turn of the twentieth century when California was the largest oil-producing economy in the United States and Los Angeles was the fastest growing metropolitan region. This dissertation traces how Los Angeles became the first city in North America where oil became a formative element of urban and industrial development: not only as fuel for transportation, but also in the infrastructures, landscapes and networks that sustain a critical dependence on oil-based energy. With a distinctive metropolitan geography, decentralized and automobile-dependent, Los Angeles became the first oil-based city in North America and thus provides an ideal case study for examining the regional dynamics of energy transition, establishment and dependence. Interwoven with the production of urban and industrial space, oil remains the primary fuel that

    Full Text Available This Molecular Dynamics (MD simulation paper presents a physical property comparison study between exfoliated graphite nanoplatelets (xGNP modified and control asphalt models, including density, glass transition temperature, viscosity and thermal conductivity. The three-component control asphalt model consists of asphaltenes, aromatics, and saturates based on previous references. The xGNP asphalt model was built by incorporating an xGNP and control asphalt model and controlling mass ratios to represent the laboratory prepared samples. The Amber Cornell Extension Force Field (ACEFF was used with assigned molecular electro-static potential (ESP charge from NWChem analysis. After optimization and ensemble relaxation, the properties of the control and xGNP modified asphalt models were computed and analyzed using the MD method. The MD simulated results have a similar trend as the test results. The property analysis showed that: (1 the density of the xGNP modified model is higher than that of the control model; (2 the glass transition temperature of the xGNP modified model is closer to the laboratory data of the Strategic Highway Research Program (SHRP asphalt binders than that of the control model; (3 the viscosities of the xGNP modified model at different temperatures are higher than those of the control model, and it coincides with the trend in the laboratory data; (4 the thermal conductivities of the xGNP modified asphalt model are higher than those of the control asphalt model at different temperatures, and it is consistent with the trend in the laboratory data.

  14. Kinetics of CH4 and CO2 hydrate dissociation and gas bubble evolution via MD simulation.

    Uddin, M; Coombe, D

    2014-03-20

    Molecular dynamics simulations of gas hydrate dissociation comparing the behavior of CH4 and CO2 hydrates are presented. These simulations were based on a structurally correct theoretical gas hydrate crystal, coexisting with water. The MD system was first initialized and stabilized via a thorough energy minimization, constant volume-temperature ensemble and constant volume-energy ensemble simulations before proceeding to constant pressure-temperature simulations for targeted dissociation pressure and temperature responses. Gas bubble evolution mechanisms are demonstrated as well as key investigative properties such as system volume, density, energy, mean square displacements of the guest molecules, radial distribution functions, H2O order parameter, and statistics of hydrogen bonds. These simulations have established the essential similarities between CH4 and CO2 hydrate dissociation. The limiting behaviors at lower temperature (no dissociation) and higher temperature (complete melting and formation of a gas bubble) have been illustrated for both hydrates. Due to the shift in the known hydrate stability curves between guest molecules caused by the choice of water model as noted by other authors, the intermediate behavior (e.g., 260 K) showed distinct differences however. Also, because of the more hydrogen-bonding capability of CO2 in water, as reflected in its molecular parameters, higher solubility of dissociated CO2 in water was observed with a consequence of a smaller size of gas bubble formation. Additionally, a novel method for analyzing hydrate dissociation based on H-bond breakage has been proposed and used to quantify the dissociation behaviors of both CH4 and CO2 hydrates. Activation energies Ea values from our MD studies were obtained and evaluated against several other published laboratory and MD values. Intrinsic rate constants were estimated and upscaled. A kinetic reaction model consistent with macroscale fitted kinetic models has been proposed to

  17. Dynamics of biopolymers on nanomaterials studied by quasielastic neutron scattering and MD simulations

    Science.gov (United States)

    Dhindsa, Gurpreet K.

    Neutron scattering has been proved to be a powerful tool to study the dynamics of biological systems under various conditions. This thesis intends to utilize neutron scattering techniques, combining with MD simulations, to develop fundamental understanding of several biologically interesting systems. Our systems include a drug delivery system containing Nanodiamonds with nucleic acid (RNA), and two specific model proteins, beta-Casein and Inorganic Pyrophosphatase (IPPase). RNA and nanodiamond (ND) both are suitable for drug-delivery applications in nano-biotechnology. The architecturally flexible RNA with catalytic functionality forms nanocomposites that can treat life-threatening diseases. The non-toxic ND has excellent mechanical and optical properties and functionalizable high surface area, and thus actively considered for biomedical applications. In this thesis, we utilized two tools, quasielastic neutron scattering (QENS) and Molecular Dynamics Simulations to probe the effect of ND on RNA dynamics. Our work provides fundamental understanding of how hydrated RNA motions are affected in the RNA-ND nanocomposites. From the experimental and Molecular Dynamics Simulation (MD), we found that hydrated RNA motion is faster on ND surface than a freestanding one. MD Simulation results showed that the failure of Stokes Einstein relation results the presence of dynamic heterogeneities in the biomacromolecules. Radial pair distribution function from MD Simulation confirmed that the hydrophilic nature of ND attracts more water than RNA results the de-confinement of RNA on ND. Therefore, RNA exhibits faster motion in the presence of ND than freestanding RNA. In the second project, we studied the dynamics of a natively disordered protein beta-Casein which lacks secondary structures. In this study, the temperature and hydration effects on the dynamics of beta-Casein are explored by Quasielastic Neutron Scattering (QENS). We investigated the mean square displacement (MSD) of

    Full Text Available Obiettivo del contributo è quello di proporre alcuni spunti di riflessione sul caso della città di celluloide più nota al mondo: Los Angeles. Più in particolare s’intende analizzare la stretta relazione che intercorre tra l’attrattività turistica della metropoli e l’industria cinematografica.  Come ben noto, Los Angeles continua da quasi un secolo a suggestionare l’immaginario collettivo in quanto mecca del cinema e patria di Hollywood, l’industria che ha creato il sogno americano. Tuttavia LA, oggi, è anche una delle prime dieci città mondiali. Rappresenta l’esempio di come l’industria creativa (e il cinema è creatività per definizione sia riuscita a realizzare un sistema economico e d’innovazione tecnologica che funziona come polo di attrazione sia per tutti coloro che intendono sviluppare nuove attività, non possibili in altre parti del mondo, sia per visitatori e turisti attirati da un insieme di fattori emozionali legati alla notorietà dei luoghi del sistema cinematografico e dello spettacolo. Sulla base dell’analisi della letteratura e facendo seguito a esperienze di studio sul campo, il contributo vuole evidenziare la stretta connessione costruita nel corso di più di un secolo tra Hollywood, il luogo, e Hollywood, l’industria, per dimostrare come il luogo di produzione rappresenti una componente unica del prodotto finale, un’autenticazione di qualità soggettive e simboliche in grado di amplificare il valore economico intrinseco e di provocare un’attrazione crescente di attività e persone verso l’area metropolitana di Los Angeles.   This paper discusses Los Angeles as the best-known celluloid city in the world, and focuses particularly on the close relationship between its attractiveness for tourists and the film industry. For almost a century Los Angeles has exerted influence over the collective imagination as the mecca of cinema and home of Hollywood, the industry that created the American dream

    2009-01-01

    "Stop the Sores" (STS), a humor-based syphilis prevention campaign, was implemented in response to increasing syphilis prevalence among gay and bisexual men in Los Angeles County. In 2004, 564 men completed surveys measuring exposure and reactions to the campaign and syphilis testing. Mean age was 39, and men of color comprised a significant proportion of the sample (46.8%). Most men reported being HIV-negative (79.3%). Overall, 7.8% of the sample reported ever having syphilis; HIV-positive men were six times more likely to report this. Over one half of the sample (58.5%) reported exposure to the campaign. Men reporting any recent unprotected anal sex were twice more likely (than those who did not) to see the campaign. Men of color were twice more likely than White men to report wanting to speak to their friends about it. Finally, 39.1% of men exposed to the campaign reported being tested for syphilis as a result. Factors related to higher likelihood to test for syphilis included HIV seropositive status, any recent unprotected anal insertive sex, recent use of methamphetamine, recent use of "poppers," and recent use of erectile dysfunction drugs. Although STS was somewhat effective, outreach efforts to particular subgroups may need to increase.

  20. Protocols for Late Maxillary Protraction in Cleft Lip and Palate Patients at Childrens Hospital Los Angeles

    Yen, Stephen L-K

    2011-01-01

    This paper describes the protocols used at Childrens Hospital Los Angeles (CHLA) to protract the maxilla during early adolescence. It is a modification of techniques introduced by Eric Liou with his Alternate Rapid Maxillary Expansion and Constriction (ALT-RAMEC) technique. The main differences between the CHLA protocol and previous maxillary protraction protocols are the age the protraction is attempted, the sutural loosening by alternating weekly expansion with constriction and the use of Class III elastics to support and redirect the protraction by nightly facemask wear. The CHLA protocol entirely depends on patient compliance and must be carefully taught and monitored. In a cooperative patient, the technique can correct a Class III malocclusion that previously would have been treated with LeFort 1 maxillary advancement surgery. Thus, it is not appropriate for patients requiring 2 jaw surgeries to correct mandibular prognathism, occlusal cants or facial asymmetry. The maxillary protraction appears to work by a combination of skeletal advancement, dental compensation and rotation of the occlusal planes. Microscrew/microimplant/temporary anchorage devices have been used with these maxillary protraction protocols to assist in expanding the maxilla, increasing skeletal anchorage during protraction, limiting dental compensations and reducing skeletal relapse.

  1. Water Quality Improvement Policies: Lessons Learned from the Implementation of Proposition O in Los Angeles, California

    2009-03-01

    This article evaluates the implementation of Proposition O, a stormwater cleanup measure, in Los Angeles, California. The measure was intended to create new funding to help the city comply with the Total Maximum Daily Load requirements under the federal Clean Water Act. Funding water quality objectives through a bond measure was necessary because the city had insufficient revenues to deploy new projects in its budget. The bond initiative required a supermajority vote (two-thirds of the voters), hence the public had to be convinced that such funding both was necessary and would be effective. The bond act language included project solicitation from the public, as well as multiple benefit objectives. Accordingly, nonprofit organizations mobilized to present projects that included creating new parks, using schoolyards for flood control and groundwater recharge, and replacing parking lots with permeable surfaces, among others. Yet few, if any, of these projects were retained for funding, as the city itself also had a list of priorities and higher technical expertise in justifying them as delivering water quality improvements. Our case study of the implementation of Proposition O points to the potentially different priorities for the renovation of urban infrastructure that are held by nonprofit organizations and city agencies and the importance of structuring public processes clearly so that there are no misimpressions about funding and implementation responsibilities that can lead to disillusionment with government, especially under conditions of fiscal constraints.

    Full Text Available This article explores Charles Dickens’ view of Victorian women and the effect of his perception of women on his creation of female characters in his novels. To this end, the gender issues in the Victorian era are presented along with the social reforms and industrial revolution in terms of their impact on the status of women in 19th century Victorian England. The role of actual female figures in Dickens’ personal life is also examined in order to provide an insight into the motives and inspirations behind his creation of female characters. In view of the detailed account given as to the time period and background information provided, the main issue discussed in the article is the extent of Dickens’ conformity with the Victorian ideology of women in his novels. Through the insight provided in the article, it is concluded that despite Dickens’ overall faith in the ‘Angel of the House’ concept, his fiction does not strictly follow the gender codes of the period.

    Our aim was to assess whether past discharges from a wastewater treatment plant increased metal pollutant loads in stream mobile species in a one-day baseline sampling study that included a coastal wetland. Mosquitofish (Gambusia affinis) of two sizes, black bullhead (Ameiurus melas), and crayfish (Pacifastacus leniusculus) were collected from Malibu Creek, and California killifish (Fundulus parvipinnis) of three sizes, as well as arroyo chub (Gila orcutti) were sampled from Malibu Lagoon near Los Angeles, California. Species from each locality were pooled by length, homogenized, digested by microwave wet ashing, and analyzed by simultaneous inductively coupled plasma atomic emission spectroscopy for 27 elements. Lagoon killifish 2.0-3.5 cm long contained levels of arsenic and lead above the levels for 95% of California fish, the EDL95. Black bullhead upstream of the discharge contained elevated levels of As, Cr and Se. Young mosquitofish <3 cm in length upstream of the discharge differed greatly in the order of abundance of their elements relative to larger mosquitofish and to other species collected. More sampling than this baseline study allowed was needed to determine if the wastewater treatment plant was a pollution source.

    An experimental and numerical study has been conducted to clarify fluid flow characteristics and pressure drop distributions of a cross-flow heat exchanger employing staggered wing-shaped tubes at different angels of attack. The water-side Rew and the air-side Rea were at 5 × 102 and at from 1.8 × 103 to 9.7 × 103, respectively. Three cases of the tubes arrangements with various angles of attack, row angles of attack and 90° cone angles were employed at the considered Rea range. Correlation of pressure drop coefficient Pdc in terms of Rea, design parameters for the studied cases were presented. The flow pattern around the staggered wing-shaped tubes bundle were predicted using the commercial CFD FLUENT 6.3.26 software package. Results indicated that the values of Pdc increased with the angle of attack from 0° to 45°, while the opposite was true for angles of attack from 135° to 180°. The values of Pdc for the arrangements of (θ1,2,3 = 45°), (θ1 = 45°, θ2 = 0°, θ3 = 45°), and (θ1,2,3 = 0°) were lower than those for the arrangement of (ϕ1 = ϕ2 = ϕ3 = 90°) by about 33, 53, and 91 %, respectively. Comparisons between the experimental and numerical results of the present study and those obtained by similar previous studies showed good agreements.

    Reproductive characteristics of the Pacific angel shark, Squatina californica, were evaluated from 420 specimens obtained from the artisanal fishery in La Paz Bay, Gulf of California, Mexico. Females (99 cm, 6000 g) were larger than males (95 cm, 5000 g) in terms of both total length (L(T)) and body mass (M(T)). The overall sex ratio was significantly different from the expected 1:1, suggesting sexual segregation of mature individuals in La Paz Bay. Males had developed reproductive organs and calcified claspers from 72 cm L(T); the median size at maturity (LT50 ) was 75.6 cm. In females, only the left ovary was functional and mature ovarian follicles were present from 77 cm L(T); the estimated LT50 was 77.7 cm. For the 10 gravid females sampled, uterine fecundity was between two and 10 embryos. Mature, non-gravid females with small and large ovarian follicles appeared simultaneously with gravid females with follicles that did not exceed 1.9 cm diameter.

  6. Urban Infestation Patterns of Argentine Ants, Linepithema humile, in Los Angeles

    Full Text Available Infestations of buildings by Argentine ants, Linepithema humile (Mayr, were monitored on the campus of the University of California, Los Angeles. Foraging ant activity peaked during the hotter months of the year. The mean monthly maximum temperature, but not rainfall, positively correlated with indoor infestation frequency. Neither garden size nor the predominant groundcover vegetation correlated with the number of foraging ants at baits within gardens. Although the number of foraging ants outside a building varied over 40-fold, ant density in gardens did not predict the likelihood of infestation within the building. Also, the type of vegetative groundcover employed did not predict infestation frequency. There was, however, a significant negative relationship between the size of the garden outside of a building and the number of infestations. Given the large foraging area of L. humile workers, buildings next to small gardens may be infested simply because they lie within the “normal” foraging area of a colony. The best predictor of which rooms were infested within buildings was the presence of a water source. Thus providing water for ant colonies outside and away from buildings may be one method of integrated pest management to reduce the proclivity of ants to infest structures.

    Background On August 24, 2011, 31 US-bound refugees from Kuala Lumpur, Malaysia (KL) arrived in Los Angeles. One of them was diagnosed with measles post-arrival. He exposed others during a flight, and persons in the community while disembarking and seeking medical care. As a result, 9 cases of measles were identified. Methods We estimated costs of response to this outbreak and conducted a comparative cost analysis examining what might have happened had all US-bound refugees been vaccinated before leaving Malaysia. Results State-by-state costs differed and variously included vaccination, hospitalization, medical visits, and contact tracing with costs ranging from $621 to $35,115. The total of domestic and IOM Malaysia reported costs for US-bound refugees were $137,505 [range: $134,531 - $142,777 from a sensitivity analysis]. Had all US-bound refugees been vaccinated while in Malaysia, it would have cost approximately $19,646 and could have prevented 8 measles cases. Conclusion A vaccination program for US-bound refugees, supporting a complete vaccination for US-bound refugees, could improve refugees' health, reduce importations of vaccine-preventable diseases in the United States, and avert measles response activities and costs.

    A subsea hot tap was conducted near the gas production platforms in Angel Field, Australia in September 2007 and verified as the largest no. 900 subsea hot tap by Australian authorities. This paper outlines the subsea tapping process, risks and safety issues in deep water environment, including the need to ensure 100% system accuracy and that the machine fluids used to operate the subsea tapping machines were environmentally friendly. The testing phase included land and water testing. In the land tests, issues relating to metal hardness, temperature, pressure and ocean currents that affected machine stability, torque and cutting rate were considered. All preliminary design and testing focused on being able to mount the tapping machine to a pre-existing hot-tap flange and conduct the tapping operation, start to finish, preferably without changing the cutter. The water depth tests took place inside a pressurized, underwater hyperbaric chamber. The equipment repeated the land testing process in conditions duplicating that of the actual project site. Timing was also measured in multiple climatic conditions (except water depth) to obtain an estimation of various scenarios. The field tapping process was conducted without problems in over six hours with a single cutter and without any stalls. (author)

    This paper described the development of a prototype fuel cell-powered shunt locomotive for urban rail use. The prototype was funded by a public-private partnership involving the BNSF Railway Company and the United States Department of Defense in an effort to reduce air pollution in urban railyards; increase energy security of the rail transport system by using hydrogen as fuel; reduce atmospheric greenhouse-gas emissions; and serve as a mobile backup power source for critical infrastructure on military bases. Railyard demonstrations were performed at the Commerce and Hobart railyards in the Los Angeles metro area. The hybrid locomotive is the heaviest and most powerful fuel cell land vehicle built today. It weighs 127 tonnes and gets continuous net power of 250 kW from its PEM fuel cell prime mover. Its transient power is well in excess of 1 MW. Its fourteen carbon-fiber composite compressed-hydrogen storage tanks, located at the roofline, have a combined storage of 70 kg at 350 bar. The system provides fuel for a rigorous 8-10 hour shunt-locomotive duty cycle. This paper focused on test results for this locomotive which was scheduled for completion by the end of 2008.

    CicLAvia in Los Angeles, CA is the open streets program that closes streets to motorized vehicles and invites people to walk, run, play or ride their bicycles on these streets, allowing them to experience the city in a new way and get exercise at the same time. Since the events reduce the motorized traffic flow, which is a significant source of air pollution, on the streets, it is reasonable to hypothesize that the CicLAvia events can reduce the concentrations of traffic-emitted air pollutants during the road closure. This study is the first experiment to test this hypothesis. The on-road and community-wide ultrafine particle (UFP) and PM2.5 were measured on the Event-Sunday (October 5th, 2014) and the Pre- and Post- Sundays (September 28(th) and October 12(th), 2014). Data analysis results showed the on-road UFP and PM2.5 reduction was 21% and 49%, respectively, and the community-wide PM2.5 reduction was 12%.

    The American Heart Association (AHA) Scientific Sessions were held for the first time in Los Angeles in 2012, with the most up-to-date basic and clinical science in the field presented and heard by physicians, research scientists, students, and paramedical personnel from 100 countries. Japan accounted for the second highest number of submitted abstracts and the Japanese Circulation Society actively contributed to the success of the AHA Scientific Sessions this year. The Late-Breaking Clinical Trial sessions comprised 27 clinical studies presented in the main hall. The FREEDOM study revealed the superiority of using a coronary artery bypass graft for diabetic multivessel coronary artery diseases over percutaneous coronary intervention using a drug-eluting stent. A new peptide hormone, serelaxin, improved dyspnea in heart failure patients and significantly reduced mortality rates according to the RELAX-AHF study. In the basic sciences, primary necrosis in mitochondria was the hot topic, while genetics, including genome-wide association studies, and epigenetics were strong features of the basic and clinical cardiovascular (CV) science. It was also clear that regenerative medicine is now part of mainstream CV research, with several clinical trials underway and many basic research projects ongoing around the world. Induced pluripotent stem cells in particular have the potential to change CV medicine, and will underpin the next era of regenerative medicine and personal therapies for heart diseases.

    As part of a comprehensive approach to combating the obesity epidemic, the Los Angeles County Department of Public Health launched the "Sugar Pack" health marketing campaign in fall 2011. Carried out in three stages, the campaign sought to educate and motivate the public to reduce excess calorie intake from sugar-sweetened beverage consumption. The primary Sugar Pack creative concepts provided consumers with information about the number of sugar packs contained in sugary drinks. Data from formative market research as well as lessons from previous campaigns in other U.S. jurisdictions informed the development of the materials. These materials were disseminated through a multipronged platform that included paid outdoor media on transit and billboards and messaging using social media (i.e., Twitter, Facebook, YouTube, and sendable e-cards). Initial findings from a postcampaign assessment indicate that the Sugar Pack campaign reached broadly into targeted communities, resulting in more than 515 million impressions. Lessons learned from the campaign suggest that employing health marketing to engage the public can lead to increased knowledge, favorable recognition of health messages, and self-reported intention to reduce sugar-sweetened beverage consumption, potentially complementing other obesity prevention strategies in the field.

    Based on OpenSHA and HAZUS-MH, we present loss estimates for an earthquake rupture on the recently identified Puente Hills blind-thrust fault beneath Los Angeles. Given a range of possible magnitudes and ground motion models, and presuming a full fault rupture, we estimate the total economic loss to be between $82 and $252 billion. This range is not only considerably higher than a previous estimate of $69 billion, but also implies the event would be the costliest disaster in U.S. history. The analysis has also provided the following predictions: 3,000-18,000 fatalities, 142,000-735,000 displaced households, 42,000-211,000 in need of short-term public shelter, and 30,000-99,000 tons of debris generated. Finally, we show that the choice of ground motion model can be more influential than the earthquake magnitude, and that reducing this epistemic uncertainty (e.g., via model improvement and/or rejection) could reduce the uncertainty of the loss estimates by up to a factor of two. We note that a full Puente Hills fault rupture is a rare event (once every ???3,000 years), and that other seismic sources pose significant risk as well. ?? 2005, Earthquake Engineering Research Institute.

    Glyoxal (CHOCHO) is the simplest alpha-dicarbonyl and one of the most prevalent dicarbonyls in the atmosphere. It is an oxidation product of isoprene, and is also formed from the photooxidation of anthropogenic hydrocarbons, including aromatics and ethyne. In addition to its importance as a source of HOx, previous studies indicate that glyoxal reacts heterogeneously to form secondary organic aerosol. For the CalNex field campaign during summer 2010, we deployed a new glyoxal field instrument in Pasadena, California. This instrument consists of a broadband LED light source coupled to a cavity enhanced absorption spectrometer (IBBCEAS). The effective pathlength of the instrument is approximately 18 km. The measurement precision of the glyoxal instrument allows us to observe diurnal variability and trends. The glyoxal measurements were co-located with a comprehensive set of hydrocarbon measurements. These included the important photochemical precursors for CHOCHO, with measurements of isoprene, ethyne, ethene, monoterpenes, aromatics, and methylbutenol. We use the precursor concentrations to evaluate expected glyoxal concentrations. The difference between the expected gas-phase production of glyoxal and the measured concentrations indicates the contribution that glyoxal makes to secondary organic aerosol formation in Los Angeles.

    The desorption mechanism of water from the hydrophilic mesopores of MCM-41 was studied using positron annihilation lifetime spectroscopy (PALS) and attenuated total reflection Fourier transform infrared spectroscopy supplemented with molecular dynamics (MD) simulation. PALS results indicated that water molecules do not undergo sequential evaporation in a simple layer-by-layer manner during desorption from MCM-41 mesopores. The results suggested that the water column inside the uniform cylindrical mesopore become stretched during desorption and induces cavitation (as seen in the case of ink-bottle type pores) inside it, keeping a dense water layer at the hydrophilic pore wall, as well as a water plug at both the open ends of the cylindrical pore, until the water was reduced to a certain volume fraction where the pore catastrophically empties. Before being emptied, the water molecules formed clusters inside the mesopores. The formation of molecular clusters below a certain level of hydration was corroborated by the MD simulation study. The results are discussed.

    Full Text Available Fundamental understanding of micro-mechanical behaviors in bitumen, including phase separation, micro-friction, micro-abrasion, etc., can help the pavement engineers better understand the bitumen mechanical performances at macroscale. Recent researches show that the microstructure evolution in bitumen will directly affect its surface structure and micro-mechanical performance. In this study, the bitumen microstructure and micro-mechanical behaviors are studied using Atomic Force Microscopy (AFM experiments, Phase Dynamics Theory and Molecular Dynamics (MD Simulation. The AFM experiment results show that different phase-structure will occur at the surface of the bitumen samples under certain thermodynamic conditions at microscale. The phenomenon can be explained using the phase dynamics theory, where the effects of stability parameter and temperature on bitumen microstructure and micro-mechanical behavior are studied combined with MD Simulation. Simulation results show that the saturates phase, in contrast to the naphthene aromatics phase, plays a major role in bitumen micro-mechanical behavior. A high stress zone occurs at the interface between the saturates phase and the naphthene aromatics phase, which may form discontinuities that further affect the bitumen frictional performance.

    New theoretical procedures were proposed for the heats of vaporization (ΔHvap) and sublimation (ΔHsub) predictions by adopting effective fragment potential version 2-molecular dynamics (EFP2-MD) simulations. The particular EFP2, as generated by HF/6-31++G(2d,2p), yielded excellent results in the predictions of ΔHvap, where mean absolute deviation (MAD) and root-mean-square deviation (RMSD) for 16 molecules were 0.34 and 0.44 kcal/mol, respectively. By introducing a uniform scaling factor, we further derived a prediction procedure for ΔHsub, where its MAD and RMSD were 0.76 and 0.90 kcal/mol, respectively. Because EFP2-MD does not require any ab initio computations during simulation, computational overhead of our procedures is minimal. We believe that our new procedures for the ΔHvap and ΔHsub predictions could be widely applicable in the areas where accurate chemical information for virtual molecules is critical.

    A computational analysis of the Overhauser effect is reported for the proton, methyl carbon, and carbonyl carbon nuclei of liquid acetone doped with the nitroxide radical TEMPOL. A practical methodology for calculating the dynamic nuclear polarization (DNP) coupling factors by accounting for both dipole-dipole and Fermi-contact interactions is presented. The contribution to the dipolar spectral density function of nuclear spins that are not too far from TEMPOL is computed through classical molecular dynamics (MD) simulations, whereas the contribution of distant spins is included analytically. Fermi contacts are obtained by subjecting a few molecules from every MD snapshot to ab initio quantum mechanical calculations. Scalar interaction is found to be an essential part of the (13)C Overhauser DNP. While mostly detrimental to the carbonyl carbon of acetone it is predicted to result in large enhancements of the methyl carbon signal at magnetic fields of 9 T and beyond. In contrast, scalar coupling is shown to be negligible for the protons of acetone. The additional influence of proton polarization on the carbon DNP (three-spin effect) is also analyzed computationally. Its effect, however, is concluded to be practically insignificant for liquid acetone.

  20. An MD-PhD program in Brazil: students’ concepts of science and of common sense

    Full Text Available In 1995, a pioneering MD-PhD program was initiated in Brazil for the training of medical scientists in experimental sciences at the Federal University of Rio de Janeiro. The program’s aim was achieved with respect to publication of theses in the form of papers with international visibility and also in terms of fostering the scientific careers of the graduates. The expansion of this type of program is one of the strategies for improving the preparation of biomedical researchers in Brazil. A noteworthy absence of interest in carrying out clinical research limits the ability of young Brazilian physicians to solve biomedical problems. To understand the students’ views of science, we used qualitative and quantitative triangulation methods, as well as participant observation to evaluate the students’ concepts of science and common sense. Subjective aspects were clearly less evident in their concepts of science. There was a strong concern about "methodology", "truth" and "usefulness". "Intuition", "creativity" and "curiosity" were the least mentioned thematic categories. Students recognized the value of intuition when it appeared as an explicit option but they did not refer to it spontaneously. Common sense was associated with "consensus", "opinion" and ideas that "require scientific validation". Such observations indicate that MD-PhD students share with their senior academic colleagues the same reluctance to consider common sense as a valid adjunct for the solution of scientific problems. Overcoming this difficulty may be an important step toward stimulating the interest of physicians in pursuing experimental research.
