Preview of the new CERN website to be published on 5 May. Opinion is split among CERNois when talking about Dan Brown’s book Angels & Demons. Should he be praised for bringing particle physics into the spotlight or should he be demonised for the ‘creative liberties’ he took - for example, although it would be useful for the international collaborations, CERN doesn’t actually have its own private airport and supersonic jet. But love it or hate it, with the upcoming release of the multi-million dollar Hollywood film adaptation, Angels & Demons will introduce a huge new audience to CERN.

    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 ...

  16. ANGEL CAPITAL AND APPLICATIONS IN TURKEY

    Full Text Available Successful entrepreneurship activity through angel capital that has a long history around the world, is increasing in Turkey day by day although it is new and limited. Angel investors while being wealthy people who take place in an enterprise as core capital, they also supply counsel providing their experience gained from their entrepreneurship activities. Entrepreneurs call these successful people angels because when they are in need, angels give them feedback and contribute to their entrepreneurship significantly. An angel investor is known as one kind of private investor who invests in firms that have a high risk but a high potential to grow. On the other hand, angel investors who provide friendly support with their own experience to entrepreneurs, play a significant role in entrepreneurial finance today. They help entrepre- neurship exist and improve significantly while contributing to economic development. The use of this financing method that the usage in the United States and other countries is spreading rapidly, is also in- creasing steadily in Turkey. Today, we often hear that many of the world-famous firms prefer angel capital financing. This study features initiative and entrepreneurship, entrepreneurial finance and research on angel capital financing. The results of the implementation of a small but growing number of entrepreneurs and angel investors in Turkey are shown in this study with their current direction and contributions.

    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.

  1. Cavity Voltage Phase Modulation MD

    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.

  6. Should government support business angel networks? The tale of Danish business angels network

    DEFF Research Database (Denmark)

    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...

We meet her in part of Divine Comedy calledParadise as a guide into Celestial Empire. I have ever been interested in structure of Celestial Empire and mesmerised by Dante. That was the reason to write this paper. I try to re-construct and complete Dante’s interpretation of the hierarchy of Celestial Empire with focusing on angels. Angels are also called Intellects or forms of the Heaven or substances between the Earth and Heaven or blissful Beings. I also try to find out the answer what happened to souls of people who died, especially to souls of innocent children. In memory of Michalka Režnáková (1984-1995.

    In short, the VNA of Los Angeles has a proud tradition. For almost 50 years, it has been providing needed health care and supportive services to the chronically ill and disabled in their own homes. Thanks to the efforts of all who made these traditions, the VNA also has a bright future. The VNA is a source of pride in California not only because of what it has accomplished but also because of what the good people of the VNA will be able to accomplish in the future. The VNA of Los Angeles is a valuable community resource whose services will be needed now more than ever before. The combination of demographics, consequences of the greying of America, the effects of the expected AIDS epidemic, and the evolution of new technology all point in the direction of home care. The VNA is already in the vanguard of what surely will become a national trend. Because of these contributions--past, present, and future--CARING is proud to salute the Visiting Nurse Association of Los Angeles.

    Tohoku University was the first National University to admit three women students in Japan in 1913. To support the university's traditional ``open-door'' policy, various projects have been promoted throughout the university since its foundation. A government plan, the Third-Stage Basic Plan for Science and Technology, aims to increase the women scientist ratio up to 25% nationwide. In order to achieve this goal, the Tohoku Women's Hurdling Project, funded by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), was adopted in 2006. This project is threefold: support for child/family, improvement of facilities, and support for the next generation, which includes our Science Angels program. ``Science Angels'' are women PhD students appointed by the university president, with the mission to form a strong support system among each other and to become role-models to inspire younger students who want to become researchers. Currently, 50 women graduate students of the natural sciences are Science Angels and are encouraged to design and deliver lectures in their areas of specialty at their alma maters. Up to now, 12 lectures have been delivered and science events for children in our community have been held-all with great success.

  16. 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.

    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! ...

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.

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.

    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.)

    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.

    The ballistic optics is designed to improve the understanding of optical errors and BPM systematic effects in the critical triplet region. The particularity of that optics is that the triplet is switched off, effectively transforming the triplets on both sides of IR1 and IR5 into drift spaces. Advantage can be taken from that fact to localize better errors in the Q4-Q5-triplet region. During this MD this new optics was tested for the first time at injection with beam 2.

    2013-12-01

    Airborne observations show that Los Angeles (LA) is a large source of methane to the atmosphere, yet the sources of excess methane from the urban area are poorly constrained. We used a mobile laboratory, a Ford Transit van equipped with cavity ring down spectrometers (Picarro, Inc.), to measure greenhouse gases (CH4, CO2, and CO) mole fractions in LA. On-road surveys across the LA Basin were conducted seasonally to determine patterns of CH4 enrichment in space and over time, with a focus on quantifying methane leaks from known sources. We found fugitive leaks and elevated CH4 concentrations throughout the LA Basin. Some were associated with known sources, such as landfills, wastewater treatment, and oil and gas infrastructure, while others had an unknown origin. Urban CH4 enrichment varied over the course of the year, largely due to seasonal changes in meteorological conditions. Nevertheless, our mobile surveys revealed CH4 hotspots (>200 ppb elevated with respect to background levels) that persisted among seasons. High CH4 concentrations were most easily predicted by proximity to methane sources, particularly near the coast, while elevated CH4 levels were more evenly dispersed in inland areas. CH4 hotspots had a disproportionate impact on excess methane relative to the area they accounted for, typically providing more than a quarter of excess methane measured on a transect. These data improve estimates of the relative roles of specific leaks and emission sectors to LA's excess methane. Depending on the cost of reducing these CH4 leaks, a focus on CH4 emissions may prove an effective way to reduce LA's greenhouse gas emissions in the near term.

  1. The informal investment context: specific issues concerned with business angels

    Directory of Open Access Journals (Sweden)

    Jon Hoyos Iruarrizaga

    2013-01-01

    Full Text Available Informal investors play a key role to meet the financing needs of business projects in early stages. However, this is a group in which there are different kinds and ways of dealing with investment. One of these profiles is associated with the figure known as business angel, whose main distinguishing feature is its ability to add smart capital in the form of knowledge, experience and contacts. The aim of this paper is to determine to what extent the specific profile of business angels differ from the rest of informal investors. With a sample of over 800 informal investors in Spain, the empirical results of this study show that the higher income, skills and entrepreneurial training and the less family ties to the entrepreneur, the greater the probability of belonging to business angel investment group.

    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.

  10. DFT-MD simulations of shocked Xenon

    Magyar, Rudolph J.; Mattsson, Thomas R.

    2009-03-01

    Xenon is not only a technologically important element used in laser technologies, jet propulsion and dental anesthesia, but it is also arguably the simplest material in which to study the metal-insulator transition at high pressure. Because of its closed shell electronic configuration, Xenon is often assumed to be chemically inert, interacting almost entirely through the van der Waals interaction, and at liquid density, is typically modeled well using Leonard-Jones potentials. However, such modeling has a limited range of validity as Xenon is known to form compounds at normal conditions and likely exhibits considerably more chemistry at higher densities when hybridization of occupied orbitals becomes significant. In this talk, we present DFT-MD simulations of shocked liquid Xenon with the goal of developing an improved equation of state. The relative importance of the van der Waals interaction compared to other Coulomb interactions is considered, and estimates of the relative accuracy of various density functionals are quantified. Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

    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.

    Colliding the beams during the squeeze to profit from Landau damping due to head--on beam-beam and beta--star leveling are two operational modes that may have to be used in a not so distant future at the LHC. This MD aimed at improving the orbit control during the squeeze with much improved handling of orbit feedback references and at evaluating instruments and techniques to maintain the beam in collisions with active feedback on luminosity or beam position. This MD also integrated for the first time synchronized collimator measurements. Comparison of the settings with the previous MD allowed a validation of the long term stability of collide and squeeze.

    Rate constant of intermolecular electron transfer (ET) in a photoexcited donor-acceptor model system solvated by a cluster of polar molecules has been expressed in terms of the statistical distribution of the electrostatic potential energy difference between the reacting sites. This distribution has been calculated for a particular case of acetonitrile clusters at ∼ 120 K by MD computer simulation. The MD values of the cluster reorganization energy and the ET rate constant have been compared with the corresponding MD results for the donor-acceptor pair solvated in bulk acetonitrile and with theoretical predictions based on the continuum model.

The impossibility of action in Înger bătrîn/ The Old Angel (1977 and the pact-making in Îngerul slut/ The Miscreated Angel (1982, imply metamorphosis in essence, supported by the dialogue with the great texts of the world, by intertextuality (the biblical text, Shakespeare's texts -Hamlet -Yorick, texts written by Göethe, Beckett, Marlowe, Dostoevsky, J.

  9. Interseismic strain accumulation and anthropogenic motion in metropolitan Los Angeles

    Science.gov (United States)

    Argus, D. F.; Heflin, M. B.; Peltzer, G.; Crampe, F.; Webb, F. H.

    2005-05-01

    We use global positioning system (GPS) geodesy and synthetic aperture radar (SAR) interferometry to distinguish between interseismic strain accumulation and anthropogenic motion in metropolitan Los Angeles. We establish a relationship between horizontal and vertical seasonal oscillations of the Santa Ana aquifer, use this relationship to infer cumulative horizontal anthropogenic motions from cumulative vertical motions caused by water and oil resource management, and estimate horizontal interseismic velocities corrected for anthropogenic effects. Vertical anthropogenic rates from 1992 to 1999 are slower than 3 mm/yr in the Santa Ana and San Gabriel aquifers and faster than 5 mm/yr in the Chino aquifer and in many oil fields. Inferred horizontal anthropogenic velocities are faster than 1 mm/yr at 18 of 46 GPS sites. Northern metropolitan Los Angeles is contracting, with the 25 km south of the San Gabriel mountains shortening at 4.5 ±1 mm/yr (95% confidence limits). The thrust fault in an elastic edge dislocation model of the observed strain is creeping at 9 ±2 mm/yr beneath and north of a position 6 ±2 km deep and 8 ±8 km north of downtown Los Angeles. The model fault is near the Los Angeles segment of the Puente Hills thrust but south of the Sante Fe Springs segment of the thrust. Disagreement between the 6 km locking depth in the model and the 15 km seismogenic depth inferred from earthquakes suggests that the elastic continuum model may be unsatisfactory; models with different stiffnesses of sedimentary basin and crystalline basement must be investigated.

  10. Modelling Worker Residence Distribution in the Los Angeles Region

    OpenAIRE

    1993-01-01

    This paper examines the spatial pattern of worker residences with three different density functions: monocentric, polycentric, and dispersive. Analysis of the 1980 journey-to-work census data for the Los Angeles region reveals that the polycentric density function statistically explains the actual distribution better than the monocentric density function, but the dispersive density function fits best. These findings confirm a polycentric spatial pattern, and also imply that overall accessibil...

    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.

  1. Creating Meanings and Supportive Networks on the Spiritual Internet Forum "The Nest of Angels"

    Directory of Open Access Journals (Sweden)

    Marko Uibu

    2012-12-01

    Full Text Available Based on the ethnographic study of Estonian spiritual Internet forum The Nest of Angels, the article observes the process of sharing virtual social support and creating-confirming spiritual meanings. The forum, explicitly opposing the consumeristic side of new spirituality, has become popular and demonstrates the nature and various roles of contemporary spiritual angels. The study identifies two main modes in which the Nest and the presence of angels might be useful for users. Firstly, emotional support is shared, either by fellow users directly or by confirmations that angels will definitely help. Secondly, the Nest allows people to acquire knowledge both on spiritual and practical issues. As the Nest is dialogical, users can pose questions and find confirmations for their otherwise deviant experiences. Discussions in the Nest encourage everybody to interpret some situations and objects (like feathers as signs from angels. This interpreting process might change people’s perceptions of the world by adding a layer of positive emotions. The study demonstrates how the angelic presence (or at least endeavour towards the presence helps to establish and keep the tonality of benevolence which functions as the cornerstone of this virtual space. The Nest supports a specific epistemological stance manifested in the angelic, traditional ‘feminine’ values of empathy, softness, and caring. Angels and the idea of angelic presence is the main factor helping to keep the ‘high-vibrational’ and benevolent atmosphere of the forum and empowering the users inside the traditional understanding of ‘feminine softness’.

  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.

    As for the rapid extraction of source data, the rapid identification of changing data and the rapid incremental extraction of data, underlying the analysis of the working principle of the traditional shadow table, this paper proposed a kind of improved linear algorithm which merged MD5 algorithm into the ST. It scanned compared tables for the linear and eliminates unnecessary inverse operation. During scanning these tables, it employed MD5 algorithm to calculate the whole record ' fingerprint ' , it reduced the frequency and duration of string matching, and it could quickly recognize the changed records. The algorithm was verified practically, and the result shows that the proposed algorithm can improve the efficiency of data extraction in database. Incremental extraction method based on shadow table is a general incremental capturing method, and it can be implemented in any database. These applications can easily be transplanted in all kinds of platforms, so it is suitable to solve the heterogeneous database replication issues.%为了快速提取源头数据、快速识别变化记录以及实现数据的快速增量提取,在剖析传统影子表法的工作原理上,提出基于MD5算法的影子表法的改进型线性算法,对对比表进行线性扫描,排除了不必要的回扫操作;同时通过MD5算法计算整条记录的“指纹”,降低了字符串比对次数和时间,能够迅速识别出发生变化的记录.对所提出算法进行了应用测试,结果表明通过融入MD5算法后的影子表法提高了数据提取效率.基于影子表的增量提取方法是一种通用的增量捕获方法,能在任何数据库上实现;应用程序可以方便地在多种平台间移植,因此很适合解决异构数据库复制问题.

    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.

  6. Implementing Municipal Tree Planting: Los Angeles Million-Tree Initiative

    Science.gov (United States)

    Pincetl, Stephanie

    2010-02-01

    Urban forests are increasingly being seen as an important infrastructure that can help cities remediate their environmental impacts. This work reports on the first steps in implementing a million tree program in Los Angeles and the ways such a biogenic—living—infrastructure has been approached. Numbers of studies have been done to quantify the benefits of urban forests, but little has been written on the process of implementing urban tree planting programs. The investigative methods were primarily qualitative, involving interviews, attending meetings and conducting literature reviews. Results indicate that multiple nonprofit and city agency programs are involved in planting and maintaining trees and this has required coordination among groups that here-to-fore were unaccustomed to having to collaborate. The main finding that emerge from this research is that the implementation of such a program in Los Angeles is more complicated than it may seem due to several interacting factors: the need to rely on multiple public and private organizations to put trees into the ground and to maintain them; coordination of these multiple efforts must be centralized, but requires a great deal of time and effort and maybe resisted by some of the partners; funding for planting and long term maintenance must be pieced together from multiple sources; acceptance of trees by residents varies by neighborhood as does tree canopy cover; appropriate nursery supply can be limited; the location of the program within the city administration is determined by who initiates the program.

The main finding that emerge from this research is that the implementation of such a program in Los Angeles is more complicated than it may seem due to several interacting factors: the need to rely on multiple public and private organizations to put trees into the ground and to maintain them; coordination of these multiple efforts must be centralized, but requires a great deal of time and effort and maybe resisted by some of the partners; funding for planting and long term maintenance must be pieced together from multiple sources; acceptance of trees by residents varies by neighborhood as does tree canopy cover; appropriate nursery supply can be limited; the location of the program within the city administration is determined by who initiates the program.

    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.

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

    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.

    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.

  12. MD210 Note: Creation of Hollow Bunches in the PSB

    2016-01-01

    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 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.

    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. PMID:12294981

    This study provides an assessment of the potential impacts of climate change on the Eastern Sierra Nevada snowpack and snowmelt timing, using a combination of empirical (i.e., data-based) models, and computer simulation models forced by GCM-projected 21st century climatology (IPCC 2007 AR4 projections). Precipitation from the Eastern Sierra Nevada is one of the main water sources for Los Angeles' more than 4 million people - a source whose future availability is critical to the city's growing population and large economy. Precipitation in the region falls mostly in winter and is stored in the large natural reservoir that is the snowpack. Meltwater from the Eastern Sierra is delivered to the city by the 340-mile long Los Angeles Aqueducts. The analysis is focused on the nature of the impact to the LAA water supplies over the 21st century due to potential climate change, including volume of precipitation, the mix of snowfall and rainfall, shifts in the timing of runoff, interannual variability and multi-year droughts. These impacts further affect the adequacy of seasonal and annual carryover water storage, and potentially water treatment. Most of the snow in the 10,000 km^2 Mono-Owens basins that feed the LAA occurs in a relatively narrow, 10-20 km wide, high-elevation band on the steep slopes of 20 smaller basins whose streams drain into the Owens River and thence LAA. Extending over 240 km in the north-south direction, these basins present special challenges for estimating snowpack amounts and downscaling climate-model data. In addition, there are few meteorological stations and snow measurements in the snow-producing parts of the basins to drive physically based hydrologic modeling.

    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.

    Measurements made since the beginning of run II at 6.5 TeV have shown that there is a large discrepancy in the instability thresholds between single bunches and trains of 72 bunches with 25ns spacing, whereas the same result is expect for pure impedance-induced instabilities. One possible explanation is that the presence of electron cloud is affecting the beam stability. This MD will attempt to determine if electron cloud is the dominant mechanism affecting beam stability.

  10. The Class of 1989 and post-MD training

    Science.gov (United States)

    Ryten, E; Thurber, A D; Buske, L

    1998-01-01

    BACKGROUND: "The Class of 1989" is a longitudinal study of 1722 people who were awarded an MD degree by a Canadian university in 1989. This paper reports on the details of their post-MD training up to spring 1996. METHODS: Several medical professional and educational associations in Canada and the United States provided year-by-year information on field and location of post-MD training, certification achieved, whether in practice and location of practice through to spring 1996. Information from all sources was linked to a list of 1989 medical school graduates. RESULTS: Of the 1722 graduates 57 (3.3%) never entered post-MD training in Canada; 147 (8.5%) did 1 or more years of training in the United States. A total of 222 graduates (12.9%) took a break of at least 1 year from training, and 301 (17.5%) changed their choice of field or specialty after starting training. Substantial numbers took 1 or more years longer to complete training than would be expected based on the prescribed length of the training program chosen. The field or specialty choices of the cohort produced a generalist:specialist ratio of 58:42. The final numbers in several fields depended heavily on trainees changing their initial career choice. INTERPRETATION: The data point out widely differing and often very long lead times from start to completion of training. Since 1993, changes to licensure requirements have reduced opportunities for recent graduating cohorts to delay final career choices, take a break in training, prolong training or change initial career choices. Rigidities in the post-1993 training environment point to the emergence of a number of serious problems, such as dissatisfaction and high anxiety levels among residents, licensing authorities being faced with people who have not completed a training program to certification, and insufficient provision of positions for post-MD training because of underestimates of the time needed to complete training programs.

  1. The Importance Of Angel Investors In Financing The Growth Of Small And Medium Sized Enterprises

    Directory of Open Access Journals (Sweden)

    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.

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

    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

    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.

    Full Text Available 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 Keywords: Forest simulator, Forest Management Approaches; StandsSIM-MD; forest management.

  19. 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.

    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.

    2014-01-01

    “Love is ever matter of comedies, and how and then tragedies.” says the prose writer and philosopher Francis Bacon. Love is beautiful, while the unfortunate love is destined to a tragedy. 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.

  8. Characterizing Air Toxics from Oil Field Operations in Los Angeles

    The Inglewood Oil Field in urban Los Angeles has been in operation for more than 70 years. Neighborhoods surrounding the oil field are concerned with the potential emissions of air toxics from oil field operations. The Baldwin Hills Air Quality Study focused on (1) quantifying air toxics concentrations originating from the Inglewood Oil Field operations, including drilling and well workovers, and (2) assessing the health risk of both acute and chronic exposure to air toxics emitted from oil field operations. Key pollutants identified for characterization included diesel particulate matter (DPM), cadmium, benzene, nickel, formaldehyde, mercury, manganese, acrolein, arsenic, and lead. The field study began in November 2012 and ended in November 2013. Four types of instruments were used to characterize oil field operations: (1) Aethalometers to measure black carbon (BC; as a proxy for DPM); (2) X-ray fluorescence spectrometer (XRF) for metals; (3) Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOFMS) for volatile organic compounds; and (4) meteorological sensors to help assess the wind patterns, temperature, and humidity that influence pollutant concentrations. Overall concentrations of most of the species measured in the study were quite low for an urban area. We determined that there were statistically significant increases in concentrations of DPM associated with oil field operations when winds were from the west-southwest. BC concentrations increased by 0.036 to 0.056 μg/m3, on average, when winds originated from the west-southwest, compared to annual mean BC concentrations of approximately 0.67 μg/m3. West-southwest winds occurred 53% of the time during the study. No other pollutants showed strong statistical evidence of chronic or acute risk from oil field operations.

  9. Molecular basis for Duarte and Los Angeles variant galactosemia

    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.

    2011-04-01

    Trachoma has been one of the most blinding diseases in the history of ophthalmology. From its initial description in antiquity until the late 1930s, no specific treatment or effective cure had been known, and the only expedient had been to destroy the diseased tissue containing the infectious agent, rendering the disease inactive. Virtually all medical, mechanical, and surgical treatments were unsatisfactory, with cure rates of approximately 20%. Therapy for trachoma had barely advanced from the measures used by the ancient Egyptian, Greek, and Roman physicians. All prior therapies became obsolete in 1938 when Fred Loe, MD, working on an American Indian reservation, introduced sulfanilamide as a treatment of trachoma, achieving a 90% cure rate. One of the most unusual aspects of Loe's career was that he had no formal training in ophthalmology and was completely self-taught as an ophthalmologist. PMID:21482877

    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.

  14. 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.

    We present our astrometric observations of the small near-Earth object 2011 MD (H ∼ 28.0), obtained after its very close fly-by to Earth in 2011 June. Our set of observations extends the observational arc to 73 days, and, together with the published astrometry obtained around the Earth fly-by, allows a direct detection of the effect of radiation pressure on the object, with a confidence of 5σ. The detection can be used to put constraints on the density of the object, pointing to either an unexpectedly low value of ρ=(640±330)kg m{sup −3} (68% confidence interval) if we assume a typical probability distribution for the unknown albedo, or to an unusually high reflectivity of its surface. This result may have important implications both in terms of impact hazard from small objects and in light of a possible retrieval of this target.

  17. Plasticity and Failure in Nanocrystalline BCC Metals via MD Simulation

    Energy Technology Data Exchange (ETDEWEB)

    2010-02-12

    Advances in the ability to generate extremely high pressures in dynamic experiments such as at the National Ignition Facility has motivated the need for special materials optimized for those conditions as well as ways to probe the response of these materials as they are deformed. We need to develop a much deeper understanding of the behavior of materials subjected to high pressure, especially the effect of rate at the extremely high rates encountered in those experiments. Here we use large-scale molecular dynamics (MD) simulations of the high-rate deformation of nanocrystalline tantalum at pressures less than 100 GPa to investigate the processes associated with plastic deformation for strains up to 100%. We focus on 3D polycrystalline systems with typical grain sizes of 10-20 nm. We also study a rapidly quenched liquid (amorphous solid) tantalum. We apply a constant volume (isochoric), constant temperature (isothermal) shear deformation over a range of strain rates, and compute the resulting stress-strain curves to large strains for both uniaxial and biaxial compression. We study the rate dependence and identify plastic deformation mechanisms. The identification of the mechanisms is facilitated through a novel technique that computes the local grain orientation, returning it as a quaternion for each atom. This analysis technique is robust and fast, and has been used to compute the orientations on the fly during our parallel MD simulations on supercomputers. We find both dislocation and twinning processes are important, and they interact in the weak strain hardening in these extremely fine-grained microstructures. We also present some results on void growth in nanocrystalline BCC metals under tension.

    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.

  20. MD-2 determinants of nickel and cobalt-mediated activation of human TLR4.

    Directory of Open Access Journals (Sweden)

    Alja Oblak

    Full Text Available Recent findings unexpectedly revealed that human TLR4 can be directly activated by nickel ions. This activation is due to the coordination of nickel by a cluster of histidine residues on the ectodomain of human TLR4, which is absent in most other species. We aimed to elucidate the role of MD-2 in the molecular mechanism of TLR4/MD-2 activation by nickel, as nickel binding site on TLR4 is remote from MD-2, which directly binds the endotoxin as the main pathological activator of TLR4. We identified MD-2 and TLR4 mutants which abolished TLR4/MD-2 receptor activation by endotoxin but could nevertheless be significantly activated by nickel, which acts in synergy with LPS. Human TLR4/MD-2 was also activated by cobalt ions, while copper and cadmium were toxic in the tested concentration range. Activation of TLR4 by cobalt required MD-2 and was abolished by human TLR4 mutations of histidine residues at positions 456 and 458. We demonstrated that activation of TLR4 by nickel and cobalt ions can trigger both the MyD88-dependent and the -independent pathway. Based on our results we propose that predominantly hydrophobic interactions between MD-2 and TLR4 contribute to the stabilization of the TLR4/MD-2/metal ion complex in a conformation that enables activation.

    Full Text Available Inherited disorders of hemoglobin, the most common monogenic disease, are now well understood at the molecular level, knowledge, which has led to considerable improvements in their control and management. The Brazilian population is multiethnic, and the correct characterization of the Hb D is important, mainly because the method available for detection of abnormal hemoglobins, present a migration in the same zone at alkaline pH, for Hb S, D, and G for example. In this paper we studied a family with an abnormal hemoglobin like S in alkaline electrophoresis, by appropriated methods including HPLC and molecular analysis, characterized as hemoglobin D Los Angeles.As doenças hereditária da hemoglobina são as mais comuns doenças monogênicas e atualmente bem conhecidas do ponto de vista molecular, fato este que propiciou um avanço no seu controle e manuseio.

    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.

    2010-01-01

    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.

    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.

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

    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.

    Before the discoveries of John Call Dalton, Jr., MD (1824-1889), innervation of laryngeal muscles, long-term effects of cerebellar lesions, and consequences of raised intracranial pressure were poorly understood. Dalton discovered that the posterior cricoarytenoid muscles adducted the vocal cords during inspiration. He confirmed Flourens' observations that acute ablation of the cerebellum of pigeons caused loss of coordination. Dalton observed that properly cared for pigeons gradually recovered "coordinating power." Dalton observed that prolonged raised intracranial pressure caused tachycardia and then fatal bradycardia in dogs. Before Dalton published his photographic atlas of the human brain, neuroanatomy atlases were sketched by Europeans and imported into the United States. Dalton's atlas of the human brain contained precise photographs of vertical and horizontal sections that equal modern works. Before Dalton introduced live demonstrations of animals, physiology was taught by recitation of texts only. Dalton was the first American-born professor to teach physiology employing demonstrations of live animals operated on under ether anesthesia. He wrote an essay advocating experimentation on animals as the proper method of acquiring knowledge of function and that humane animal experimentation would ultimately improve the health of man and animals. His eloquent advocacy for humane experimental physiology quelled attacks by contemporaneous antivivisectionists. Dalton was America's first experimental neurophysiologist. PMID:10994009

    Bacterial lipopolysaccharide (LPS) activates the innate immune system by forming a complex with myeloid differentiation factor 2 (MD-2) and Toll-like receptor 4 (TLR4), which is present on antigen presenting cells. MD-2 plays an essential role in this activation of the innate immune system as a member of the ternary complex, TLR4:MD-2:LPS. With the goal of further understanding the molecular details of the interaction of MD-2 with LPS and TLR4, and possibly toward engineering dominant negative regulators of the MD-2 protein, here we subjected MD-2 to a mutational analysis using yeast display. The approach included generation of site-directed alanine mutants, and ligand-driven selections of MD-2 mutant libraries. Our findings showed that: (1) proline mutations in the F119-K132 loop that binds LPS were strongly selected for enhanced yeast surface stability, (2) there was a preference for positive-charged side chains (R/K) at residue 120 for LPS binding, and negative-charged side chains (D/E) for TLR4 binding, (3) aromatic residues were strongly preferred at F119 and F121 for LPS binding, and (4) an MD-2 mutant (T84N/D101A/S118A/S120D/K122P) exhibited increased binding to TLR4 but decreased binding to LPS. These studies revealed the impact of specific residues and regions of MD-2 on the binding of LPS and TLR4, and they provide a framework for further directed evolution of the MD-2 protein.

    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.

  7. 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.

  8. Apply Metaheuristic ANGEL to Schedule Multiple Projects with Resource-Constrained and Total Tardy Cost

    Directory of Open Access Journals (Sweden)

    Shih-Chieh Chen

    2015-03-01

    Full Text Available In this paper the multiple projects resource-constrained project scheduling problem is considered. Several projects are to be scheduled simultaneously with sharing several kinds of limited resources in this problem. Each project contains non-preemptive and deterministic duration activities which compete limited resources under resources and precedence constraints. Moreover, there are the due date for each project and the tardy cost per day that cause the penalty when the project cannot be accomplished before its due date. The objective is to find the schedules of the considered projects to minimize the total tardy cost subject to the resource and precedence constraints. Since the resource-constrained project scheduling problem has been proven to be NP-Hard, we cannot find a deterministic algorithm to solve this problem efficiently and metaheuristics or evolutionary algorithms are developed for this problem instead. The problem considered in this paper is harder than the original problem because the due date and tardy cost of a project are considered in addition. The metaheuristic method called ANGEL was applied to this problem. ANGEL combines ant colony optimization (ACO, genetic algorithm (GA and local search strategy. In ANGEL, ACO and GA run alternately and cooperatively. ANGEL performs very well in the multiple projects resource-constrained project scheduling problem as revealed by the experimental results.

    If MD5 algorithm is directly used to encrypt sensitive data in database, the data is unable to be deerypted by this algorithm itself, even legitimate users query or update some data for the purpose of restoring data. The database becomes more redundant because secret keys need to be saved for reversible encryption algorithms. This paper proposes a reversible non-redundant encryption algorithm based on MD5 algorithm, which can be ~ to used encrypt and decrypt sensitive data in the database regardless of saving secret keys.%直接采用MD5算法对数据库中的敏感数据加密时,合法用户进行查询、更新等操作需要还原数据,MD5算法无法解密数据.可逆的加密算法都需要保存密钥,数据库增加了数据的冗余.本文提出一种基于MD5算法的可逆无冗余算法,实现对数据库中敏感数据进行加密、解密,而且不需要保存密钥.

  12. Electroporation of archaeal lipid membranes using MD simulations.

    2014-12-01

    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.

  13. Characterization of an Autophagy-related Gene MdATG8i from apple

    Directory of Open Access Journals (Sweden)

    2016-05-01

    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.

    Data integrity and authenticity are very important in field of information security.HMAC-MD5 algorithm is one of the algorithms that achieve this target.The performance of its software implementation is very low and its FPGA hardware implementation is much higher.For the sake of higher throughput,this paper propose a two-to-one structure.As the result,it costs only 33 cycles to process 5 12 bits data.At the same time,the design support three kinds of mode:HMAC-MD5 computation with Key,HMAC-MD5 computation without key,MD5 computation. The design contains many optimization strategies such as pre-computation, microinstruction controller, the resources reuse etc.After synthesizing by Quartus II 13.0 on Stratix III devices,the clock frequency reaches 100 MHz,the throughput reaches 1.55 Gb/s and 1 120 ALUTs logic resources have been used.%在信息安全领域,数据完整性和真实性是十分重要的.HMAC-MD5算法是实现数据完整性和真实性验证的一种算法.HMAC-MD5的软件实现性能较低,而它的 FPGA 硬件实现性能较高.为了提高 FPGA 实现的性能,提出了一种二合一的结构,处理512 bit 数据周期数降低至33拍,提高了吞吐率,同时能够支持 HMAC-MD5带密钥输入和不带密钥输入、单 MD5运算的模式选择.本设计在 Stratix III 器件上使用 QuartusII 13.0进行综合,在使用了预计算、微指令控制器、资源复用等优化策略之后,最终综合出时钟频率为100 MHz,吞吐率达到1.55 Gb/s,逻辑资源使用为1120 ALUTs.

    2016-03-01

    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.

  3. Collision Attack on the Full Extended MD4 and Pseudo-Preimage Attack on RIPEMD

    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.

    作为一种主流的加密算法,MD5算法广泛的应用于软件保护领域。在软件的注册保护中,MD5经常被用来对输入的注册信息进行加密。一般来说较为简单常见的用法是“MD5(注册名)=注册码”或是“MD5(注册名:机器码)=注册码”。这样的加密方法有一定的保护效果,但是随着破解技术的进步,对于这种保护方式,破解者只要能判断出使用了MD5算法,就可以很方便的做出注册机。不过不能因此否认MD5算法的优越性,所以对于MD5在软件的保护中应用,就要另辟蹊径了。下文中我们以一个Crackme为例,来看看如何更有效的使用MD5算法,并产生更好的保护效果。

    The aim of this MD is to quantify the impact of the stripline beam position monitor (BPM) directivity with two acquisition chain electronics systems, WBTN (Wide Band Time Normalizer) and DOROS (Diode ORbit and Oscillation System). This impact depends on the relative position and intensity of the two beams at the location of the monitor. This note explains all the procedures of the LHC MD 369, which took place on 20/07/2015 and presents the obtained results.

    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.

    1982-04-01

    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.

  20. Shanghai Alleys, Theatrical Practice, and Cinematic Spectatorship: From Street Angel (1937 to Fifth Generation Film

    Directory of Open Access Journals (Sweden)

    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.

  1. Losses from the Northridge earthquake: disruption to high-technology industries in the Los Angeles Basin.

    Science.gov (United States)

    Suarez-Villa, L; Walrod, W

    1999-03-01

    This study explores the relationship between industrial location geography, metropolitan patterns and earthquake disasters. Production losses from the 1994 Northridge earthquake to the Los Angeles Basin's most important high-technology industrial sector are evaluated in the context of that area's polycentric metropolitan form. Locations for each one of the Los Angeles Basin's 1,126 advanced electronics manufacturing establishments were identified and mapped, providing an indication of the patterns and clusters of the industry. An extensive survey of those establishments gathered information on disruptions from the Northridge earthquake. Production losses were then estimated, based on the sampled plants' lost workdays and the earthquake's distance-decay effects. A conservative estimate of total production losses to establishments in seven four-digit SIC advanced electronics industrial groups placed their value at US$220.4 million. Based on this estimate of losses, it is concluded that the Northridge earthquake's economic losses were much higher than initially anticipated. PMID:10204286

  2. 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.

  3. Methane and Ethane Measurements from a New TCCON Station in Los Angeles

    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).

    2009-01-01

    The primary cause of tick-borne relapsing fever in western North America is Borrelia hermsii, a rodent-associated spirochete transmitted by the fast-feeding soft tick Ornithodoros hermsi. We describe a patient who had an illness consistent with relapsing fever after exposure in the mountains near Los Angeles, California, USA. The patient’s convalescent-phase serum was seropositive for B. hermsii but negative for several other vector-borne bacterial pathogens. Investigations at the exposure site showed the presence of O. hermsi ticks infected with B. hermsii and the presence of rodents that were seropositive for the spirochete. We determined that this tick-borne disease is endemic to the San Gabriel Mountains near the greater Los Angeles metropolitan area. PMID:19624916

  15. Water Use in Los Angeles, California: Consumption Patterns, Ecosystem Response and Impact on Regional Water Budgets

    Science.gov (United States)

    Hogue, T. S.

    2014-12-01

    The City of Los Angeles relies heavily on external water sources, primarily the Eastern Sierra, Northern California and the Colorado River, and approximately 90% of the City's water supply is snowpack dependent. In recent years, water conservation measures have been implemented in response to regional drought, which include a tiered pricing structure and watering restrictions. As a result of implemented conservation policies, Los Angeles reported the lowest water consumption per capita per day in 2011 among cities over 1 million people in the U.S. This presentation will highlight our ongoing work to better understand the coupling between humans, ecosystems and water across the City of Los Angeles, especially during the recent drought period. Our work is unique in that we integrate social, ecological, and hydrologic data, including ten years of residential water consumption data for the entire city of Los Angeles, extensive groundwater well data, socio-economic information and remote sensing to evaluate relationships as well as spatial and temporal patterns. Developed statistical models demonstrated that Single-Family Residential (SFR) water use across the City is primarily driven by household income, landscape greenness, water rates and water volume allocation,, with higher consumption rates in the northern, warmer and more affluent parts, and lower consumption rates in the less affluent neighborhoods near Downtown. Landscape use also varies greatly across the city, averaging 50% of total SFR. Our evaluation of conservation efforts shows that the combination of mandatory watering restrictions and price increase led to a water reduction of 23%, while voluntary restrictions led to only a 6% reduction in water use. Relationships of water use to ecosystems (greenness) and groundwater variability were also evaluated and will be highlighted. Our ultimate goal is to improve predictions of human-water interactions in order to drive policy change and guide future demand

  9. 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.

  10. 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.

  11. 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.

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

    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.

  13. Fault zone regulation, seismic hazard, and social vulnerability in Los Angeles, California: Hazard or urban amenity?

    Public perception and regulation of environmental hazards are important factors in the development and configuration of cities. Throughout California, probabilistic seismic hazard mapping and geologic investigations of active faults have spatially quantified earthquake hazard. In Los Angeles, these analyses have informed earthquake engineering, public awareness, the insurance industry, and the government regulation of developments near faults. Understanding the impact of natural hazards regulation on the social and built geography of cities is vital for informing future science and policy directions. We constructed a relative social vulnerability index classification for Los Angeles to examine the social condition within regions of significant seismic hazard, including areas regulated as Alquist-Priolo (AP) Act earthquake fault zones. Despite hazard disclosures, social vulnerability is lowest within AP regulatory zones and vulnerability increases with distance from them. Because the AP Act requires building setbacks from active faults, newer developments in these zones are bisected by parks. Parcel-level analysis demonstrates that homes adjacent to these fault zone parks are the most valuable in their neighborhoods. At a broad scale, a Landsat-based normalized difference vegetation index shows that greenness near AP zones is greater than the rest of the metropolitan area. In the parks-poor city of Los Angeles, fault zone regulation has contributed to the construction of park space within areas of earthquake hazard, thus transforming zones of natural hazard into amenities, attracting populations of relatively high social status, and demonstrating that the distribution of social vulnerability is sometimes more strongly tied to amenities than hazards.

  14. Novel matrine derivative MD-1 attenuates hepatic fibrosis by inhibiting EGFR activation of hepatic stellate cells.

    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.

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

    Wang, Peng

    2015-11-01

    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.

    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.

    We present an efficient and highly accurate GP-GPU implementation of our community code, PuReMD, for reactive molecular dynamics simulations using the ReaxFF force field. PuReMD and its incorporation into LAMMPS (Reax/C) is used by a large number of research groups worldwide for simulating diverse systems ranging from biomembranes to explosives (RDX) at atomistic level of detail. The sub-femtosecond time-steps associated with ReaxFF strongly motivate significant improvements to per-timestep simulation time through effective use of GPUs. This paper presents, in detail, the design and implementation of PuReMD-GPU, which enables ReaxFF simulations on GPUs, as well as various performance optimization techniques we developed to obtain high performance on state-of-the-art hardware. Comprehensive experiments on model systems (bulk water and amorphous silica) are presented to quantify the performance improvements achieved by PuReMD-GPU and to verify its accuracy. In particular, our experiments show up to 16× improvement in runtime compared to our highly optimized CPU-only single-core ReaxFF implementation. PuReMD-GPU is a unique production code, and is currently available on request from the authors.

  18. 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.

  19. 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/.

    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.

  17. Perceptions of neighborhood safety and asthma among children and adolescents in Los Angeles: a multilevel analysis.

    Directory of Open Access Journals (Sweden)

    Marlene Camacho-Rivera

    Full Text Available BACKGROUND: Research examining the impact of neighborhoods on asthma has shown an increased interest in the role of the psychosocial environment. We examined the associations between various measures of neighborhood safety, individual and family characteristics, and asthma outcomes among children in Los Angeles. METHODS: Multilevel logistic regression models were used to analyze data on 3,114 children across 65 neighborhoods from Wave 1 of the Los Angeles Family and Neighborhood Survey (2000 to 2002. Primary caregivers reported asthma outcome and all individual covariates; home environmental characteristics were observed by the interviewer. RESULTS: In fully adjusted models, parents who reported their neighborhood fairly safe or somewhat dangerous had lower odds of reported lifetime asthma compared to those who reported their neighborhood completely safe (OR 0.71; 95% CI 0.52-0.96 and OR 0.60; 95% CI 0.42-0.88 respectively. Conversely, parents who reported they could not trust their neighbors to keep their children safe had a nearly 40% increase in lifetime asthma compared to those who reported they could trust their neighbors to keep their children safe (OR 1.39; 95% CI 1.07-1.81. CONCLUSIONS: The study demonstrates a complex pattern between various measures of neighborhood safety and asthma and suggests that these relationships may operate differently in Los Angeles. As an increasing proportion of children are growing up in newer Western and Southwestern cities, which have different physical layouts and residential segregation patterns compared to Northeast and Midwestern cities, future studies should continue to examine neighborhood psychosocial stressors and asthma in diverse contexts.

    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.

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

    Hauksson, E.; Goebel, T.; Cochran, E. S.; Ampuero, J. P.

    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.

    1997-03-01

    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.

    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. PMID:25986655

    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.

  16. Large-scale MD simulations investigating H plasma interactions with Tungsten surfaces

    Science.gov (United States)

    Cusentino, Mary Alice; Wirth, Brian

    2015-11-01

    Tungsten is a prime candidate material for the divertor in future fusion reactors such as ITER. However, the tungsten divertor will need to be able to withstand high fluxes, on the order of 1024m-2s-1, of low energy hydrogen. It is crucial to understand both the tungsten surface response as well as the hydrogen retention and recycling for the divertor region. Molecular dynamics (MD) is a useful tool to study these effects. One issue with MD is that implantation fluxes tend to be very high, on the order of 1027 m-2s-1, due to time and computational limitations. By performing large scale MD on supercomputers, it is possible to reach more realistic fluxes of 1025 m-2s-1. Results will be presented from MD simulations from a 50 nm x 50 nm x 25 nm tungsten box at 1200 K and 2000 K. Hydrogen is implanted every 10 ps based on the 60 eV depth distribution calculated by SRIM, which amounts to a flux of 4 x 1025 m-2s-1. A modified version of the Juslin bond order W-H potential is used to describe the W-H interactions. Preliminary results show an initially high retention of hydrogen that accumulates in a sub-surface region. These simulations provide insight into the early stages of surface deformation as well as hydrogen retention for the tungsten divertor.

    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.

    Even low concentrations of endotoxins can be life-threatening. As such, continuous effort has been directed toward the development of sensitive and specific endotoxin detection systems. In this paper, we report the design and fabrication of a new electrochemical endotoxin sensor based on a human recombinant toll-like receptor 4 (rhTLR4) and myeloid differentiation-2 (MD-2) complex. The rhTLR4/MD-2 complex, which specifically binds to endotoxin, was immobilized on gold electrodes through a self-assembled monolayer (SAM) technique involving the use of dithiobis(succinimidyl undecanoate) (DSU). The surface topography of the electrodes at each fabrication stage was characterized with a nanosurface profiler and atomic force microscope (AFM). The electrochemical signals generated from interactions between the rhTLR4/MD-2 complex and the endotoxin were characterized by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). A linear relationship between the peak current and endotoxin concentration was obtained in the range of 0.0005 to 5 EU/mL with a correlation coefficient (R(2)) of 0.978. The estimated limit of detection (LOD) was fairly low, 0.0002 EU/mL. The rhTLR4/MD-2 based sensors exhibited no current responses to dipalmitoylphosphatidylcholine (DPPC) bearing two lipid chains, which is structurally similar to endotoxin, indicating the high specificity of the sensors to endotoxin.

  16. 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

  19. Los Angeles Test and Polished Stone Value of ophite in Cantabria: a petrophysical interpretation

    Directory of Open Access Journals (Sweden)

    Fernández Maroto, G.

    2004-09-01

    Full Text Available Crushed aggregate obtained from certain ophite outcrops in Cantabria was tested with the Los Angeles and polished stone value (PSV procedures. Linear regression analysis was used to identify the pétrographie parameters that account for aggregate performance in these two tests. The most abundant and common minerals in the ophite were observed to condition such performance in the Los Angeles method. In PSV behaviour was determined by the existence or otherwise of a rough micro texture -the result of the existence of minerals with different hardness values-, which increases aggregate resistance to polishing action.

    2012-06-01

    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.

  1. 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.

  2. Aeromagnetic Map with Geology of the Los Angeles 30 x 60 Minute Quadrangle, Southern California

    Introduction: An important objective of geologic mapping is to project surficial structures and stratigraphy into the subsurface. Geophysical data and analysis are useful tools for achieving this objective. This aeromagnetic anomaly map provides a three-dimensional perspective to the geologic mapping of the Los Angeles 30 by 60 minute quadrangle. Aeromagnetic maps show the distribution of magnetic rocks, primarily those containing magnetite (Blakely, 1995). In the Los Angeles quadrangle, the magnetic sources are Tertiary and Mesozoic igneous rocks and Precambrian crystalline rocks. Aeromagnetic anomalies mark abrupt spatial contrasts in magnetization that can be attributed to lithologic boundaries, perhaps caused by faulting of these rocks or by intrusive contacts. This aeromagnetic map overlain on geology, with information from wells and other geophysical data, provides constraints on the subsurface geology by allowing us to trace faults beneath surficial cover and estimate fault dip and offset. This map supersedes Langenheim and Jachens (1997) because of its digital form and the added value of overlaying the magnetic data on a geologic base. The geologic base for this map is from Yerkes and Campbell (2005); some of their subunits have been merged into one on this map.

    1989-07-01

    After a large food-borne outbreak of listeriosis in Los Angeles County, California, in 1985, the California State Department of Health Services instituted mandatory reporting of Listeria monocytogenes by clinical laboratories. From September 1, 1985, through August 31, 1986, 94 cases of listeriosis were reported in Los Angeles County for an annual crude incidence rate of 12 cases per million persons. Of the 94 cases, 37 (39%) were in neonates and/or their mothers and 57 (61%) were nonperinatal. The overall case fatality rate was 31%, with a perinatal case fatality of 16% (6 fetal and 23 nonperinatal); this compares with an epidemic perinatal case fatality rate of 32%. No significant differences were observed in age-adjusted, race-specific incidence rates among nonperinatal cases or race-specific incidence rates among perinatal cases. All but 2 of the nonperinatal patients had a known predisposing risk factor for the development of listeriosis, the most common of which was a prior history of steroid therapy. A clustering of cases was not identified. No common food sources were apparent. Patients presenting as perinatal cases were more likely to have ingested Mexican-style cheese, ice cream, and yogurt than those presenting as nonperinatal cases. Improved case ascertainment through mandatory reporting and laboratory-based surveillance will establish meaningful baseline levels of listeriosis. PMID:2742430

    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。

  13. Stratigraphic controls on saltwater intrusion in the Dominguez Gap area of coastal Los Angeles

    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

  14. MdMYB1 Regulates Anthocyanin and Malate Accumulation by Directly Facilitating Their Transport into Vacuoles in Apples.

    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.

  16. Moving Beyond Active-Site Detection: MixMD Applied to Allosteric Systems.

    Science.gov (United States)

    Ghanakota, Phani; Carlson, Heather A

    2016-08-25

    Mixed-solvent molecular dynamics (MixMD) is a hotspot-mapping technique that relies on molecular dynamics simulations of proteins in binary solvent mixtures. Previous work on MixMD has established the technique's effectiveness in capturing binding sites of small organic compounds. In this work, we show that MixMD can identify both competitive and allosteric sites on proteins. The MixMD approach embraces full protein flexibility and allows competition between solvent probes and water. Sites preferentially mapped by probe molecules are more likely to be binding hotspots. There are two important requirements for the identification of ligand-binding hotspots: (1) hotspots must be mapped at very high signal-to-noise ratio and (2) the hotspots must be mapped by multiple probe types. We have developed our mapping protocol around acetonitrile, isopropanol, and pyrimidine as probe solvents because they allowed us to capture hydrophilic, hydrophobic, hydrogen-bonding, and aromatic interactions. Charged probes were needed for mapping one target, and we introduce them in this work. In order to demonstrate the robust nature and wide applicability of the technique, a combined total of 5 μs of MixMD was applied across several protein targets known to exhibit allosteric modulation. Most notably, all the protein crystal structures used to initiate our simulations had no allosteric ligands bound, so there was no preorganization of the sites to predispose the simulations to find the allosteric hotspots. The protein test cases were ABL Kinase, Androgen Receptor, CHK1 Kinase, Glucokinase, PDK1 Kinase, Farnesyl Pyrophosphate Synthase, and Protein-Tyrosine Phosphatase 1B. The success of the technique is demonstrated by the fact that the top-four sites solely map the competitive and allosteric sites. Lower-ranked sites consistently map other biologically relevant sites, multimerization interfaces, or crystal-packing interfaces. Lastly, we highlight the importance of including protein

  11. Energy transition or incremental change? Green policy agendas and the adaptability of the urban energy regime in Los Angeles

    International Nuclear Information System (INIS)

    Drawing on recent research in urban policy studies and social studies of technology, this paper examines the capability of urban energy regimes in adapting to environmental policy pressures. Focusing on the case of the City of Los Angeles, we critically analyze the transformative capacity of the city's recent energy and climate policies and the innovation patterns of its urban infrastructure regime. This case study suggests that despite considerable success in switching from coal to renewable energies, the patterns of sociotechnical change in Los Angeles still tend to supplement and sustain the existing regime. Sociotechnical change in Los Angeles tends to unfold incrementally through adjustments within the established patterns of the existing regime. - Highlights: • Theory-guided case study on the transition of the urban energy regime in Los Angeles. • Evaluation of the transformative capacity of environmental policies. • Assessment of the adaptability and innovation patterns of urban infrastructure regimes. • The policy changes have sustained the existing regime and unfold incrementally

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

    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.

    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.

    Using the IRAM Plateau de Bure Interferometer, we have searched for CO(3-2) emission from the dusty Lyman break galaxy Westphal-MD11 at z = 2.98. Our sensitive upper limit is surprisingly low relative to the system's 850 um flux density and implies a far-IR/CO luminosity ratio as elevated as those seen in local ultraluminous mergers. We conclude that the observed dust emission must originate in a compact structure radiating near its blackbody limit and that a relatively modest molecular gas reservoir must be fuelling an intense nuclear starburst (and/or deeply buried active nucleus) that may have been triggered by a major merger. In this regard, Westphal-MD11 contrasts strikingly with the lensed Lyman break galaxy MS1512-cB58, which is being observed apparently midway through an extended episode of more quiescent disk star formation.

    Molecular dynamics (MD) simulations of the zeta potential are so poor that it has become common to term their predictions "apparent". Here we demonstrate how MD methods can predict zeta potentials accurate enough they can be termed "real". The critical new aspects of our method are: (1) integrating the net average charge in surface-parallel layers from the midpoint of the fluid layer (where the electrostatic potential is zero) to and then into two solid caps, (2) determining the position of slipping plane with separate Couette flow models, and (3) calculating the charge distribution and electrostatic potential under static conditions. The solids are charge neutral surfaces composed of atoms with zero charge or charge balanced monovalent or divalent ions. The zeta potentials calculated are within a few millivolts of measured values, and the measured values fall within the simulation error bars. The zeta potentials calculated with the Helmholtz and Smoluchowski equation following current practice are 10's of mi...

    2014-01-01

    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.

    Full Text Available Introduction The main objective of this study was to assess the level of interpersonal communication skills of MD/MS resident doctors and to provide recommendations for the future. Methods Descriptive, cross sectional, qualitative and quantitative research design was used. 7- point Likert scale (0 to 6 MAAS-Global scoring instrument was used. The subjects of the research were the MD/MS residents from various departments of Maharajgunj Medical Campus (MMC of Institute of Medicine, Maharajgunj, Kathmandu. Out of 162 MD/MS residents, only 30 (18.5% MD/MS residents were selected for the sample size for the study from 1st, 2nd and 3rd year. One MD/MS resident was required four video recording to conduct four interviews with patients coming to the outpatient department. Results There was high degree of positive correlation between Information sharing and Management (r=0.746 whereas weak negative correlation on clarification and diagnosis (r=-0.011. Inter-rater correlation was established before hand and was satisfactory (p < 0.05. Conclusions This base line study of MD/MS residents shows that over all MD/MS residents are deficient in almost all the components of interpersonal communication skills. A communication skills training course in postgraduate medical education could improve the existing communication skills of the doctors in Nepal.

    Background The assessment of fitness to drive in patients with cognitive impairment is complex. The SIMARD MD was developed to assist with assessing fitness to drive. This study compares the clinical decision made by a geriatrician regarding driving with the SIMARD MD score. Methods Patients with a diagnosis of mild dementia or mild cognitive impairment, who had a SIMARD MD test, were included in the sample. A retrospective chart review was completed to gather diagnosis, driving status, and cognitive and functional information. Results Sixty-three patients were identified and 57 met the inclusion criteria. The mean age was 77.1 years (SD 8.9). The most common diagnosis was Alzheimer’s disease in 22 (38.6%) patients. The mean MMSE score was 24.9 (SD 3.34) and the mean MoCA was 19.9 (SD 3.58). The mean SIMARD MD score was 37.2 (SD 19.54). Twenty-four patients had a SIMARD MD score ≤ 30, twenty-eight between 31–70, and five scored > 70. The SIMARD MD scores did not differ significantly compared to the clinical decision (ANOVA p value = 0.14). Conclusions There was no association between the SIMARD MD scores and the geriatricians’ clinical decision regarding fitness to drive in persons with mild dementia or mild cognitive impairment.

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

    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.

    A multiscale approach, Molecular Dynamics/Order Parameter eXtrapolation (MD/OPX), to the all-atom simulation of large bionanosystems is presented. The approach starts with the introduction of a set of order parameters (OPs) automatically generated with orthogonal polynomials to characterize the nanoscale features of bionanosystems. The OPs are shown to evolve slowly via Newton’s equations and the all-atom multiscale analysis (AMA) developed earlier1 demonstrates the existence of their stochas...

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

    KAUST Repository

    Liang, Tengfei

    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.

  13. Cyber against punk: Greg Bear’s Queen of Angels as metamorphosed cyberpunk

    Directory of Open Access Journals (Sweden)

    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.

  14. Expanding Urban Metabolism: Coupling Methodologies and Integrating Social Factors, a Pilot for Los Angeles County

    Pincetl, S.

    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.

    Secondhand smoke is dangerous to a person's health at any level of exposure. Yet policies that prevent smoking are not in place for a majority of market-rate multi-unit housing complexes, according to a new survey of nearly 1,000 apartment dwellers in the city of Los Angeles. Approximately 37 percent of respondents reported that secondhand smoke had drifted into their apartments in the past year. Households with members of vulnerable populations, such as children or individuals with chronic conditions, are more likely to report smoke drifting from adjacent units. Four out of five respondents--including more than half of those who self-reported currently smoking--supported a smoke-free policy in common areas and/or individual units. PMID:27197310

    Full Text Available Regarding the transformations produced by the housing projects for the Olympic Games, the construction and following reuse of the Olympic Villages is an interesting studying matter. During the hundred-year-old history of the modern Olympics the realization of the Olympic Village, which finds reference in the de Coubertin’s writings, and the town planning transformations, to this correlated, have revealed in different ways. The essay mainly concerns the origins of the Olympic Village and the first settlements which characterized the Games in the thirties: Los Angeles 1932 and Berlin 1936. In these two cities, even though with different motivations, politico-economical stimulus and different images, the prototypes of the modern Olympic sport facilities, which find in the village an in the stadium the symbol of the event, were born.

  18. Risky Sexual Behaviors among a Sample of Gang-identified Youth in Los Angeles

    2011-01-01

    Gang youth are at an increased likelihood of participating in unsafe sexual behaviors and at an elevated risk of exposure to sexually transmitted infection (STIs), including HIV. This manuscript presents quantitative and qualitative data on sexual behaviors among a sample of predominately heterosexual, male gang youth aged 16 to 25 years interviewed in Los Angeles between 2006 and 2007 (n = 60). In particular, sexual identity, initiation and frequency of sex, and number of sexual partners; use of condoms, children, and other pregnancies; group sex; and STIs and sex with drug users. We argue that gang youth are a particular public health concern, due to their heightened risky sexual activity, and that behavioral interventions targeting gang youth need to include a component on reducing sexual risks and promoting safe sexual health.

    2012-02-01

    Full Text Available Attributing observed CO2 variations to human or natural cause is critical to deducing and tracking emissions from observations. We have used in situ CO2, CO, and planetary boundary layer height (PBLH measurements recorded during the CalNex-LA (CARB et al., 2008 ground campaign of 15 May–15 June 2010, in Pasadena, CA, to deduce the diurnally varying anthropogenic component of observed CO2 in the megacity of Los Angeles (LA. This affordable and simple technique, validated by carbon isotope observations, is shown to robustly attribute observed CO2 variation to anthropogenic or biogenic origin. During CalNex-LA, local fossil fuel combustion contributed up to ~50 % of the observed CO2 enhancement overnight, and ~100 % during midday. This suggests midday column observations over LA, such as those made by satellites relying on reflected sunlight, can be used to track anthropogenic emissions.

  20. Case-control study of intracranial meningiomas in women in Los Angeles County, California

    International Nuclear Information System (INIS)

    A case-control study was conducted among women in Los Angeles County to investigate possible causes of intracranial meningiomas. Questionnaires sought information from patients and from a neighbor of each one on characteristics and past experiences that might be associated with the development of this disease. Information was obtained on 188 matched patient-neighbor pairs. Three primary factors appeared to be associated with meningioma occurrence: 1) a history of head trauma (odds ratio = 2.0, p = 0.01), 2) consumption of certain cured meats (odds ratio = 2.8, p = less than 0.01), and 3) exposure to medical and dental diagnostic X-rays to the head. For diagnostic X-rays, the strongest association was with early exposure (less than 20 yr old) to full-mouth dental X-ray series

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

    Science.gov (United States)

    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

    1980-12-01

    During 1977, there were 289 pesticide exposure incidents involving animals that were handled by the Thomas J. Fleming Memorial Poison Information Center in Los Angeles. Almost all of this service was provided to veterinarians and most of the incidents involved dogs. Cases handled by this center are considered typical for small animal practices in urban areas of California. Ingestion was the major route of exposure. As recently as 10 years ago, arsenic, strychnine, and phosphorus were major causes of such poisonings. During 1977, the n-methylcarbamates (27%), anticoagulants (19%), and organo-phosphates (15%) were the major pesticides involved in exposure incidents. Lesser percentages of cases attributed to a specific chemical included: Vacor (5%), metaldehyde (4%), chlorinated hydrocarbons (4%), and arsenicals (4%). A variety of other pesticides, classified as miscellaneous, were also involved in poisonings to a lesser extent.

    2005-09-23

    In April 2004, the Los Angeles County Department of Health Services (LACDHS) received reports of work-related exposure to human immunodeficiency virus (HIV) in the heterosexual segment of the adult film industry in California. This report summarizes an investigation by LACDHS into four work-related HIV-transmission cases among adult film industry workers. The investigation was initiated April 20, 2004, and joined by the California Department of Industrial Relations, Division of Occupational Safety and Health (Cal/OSHA) on April 21, 2004, and by CDC on May 18, 2004. This investigation identified important and remediable gaps in the prevention of HIV and other sexually transmitted diseases (STDs) in the adult film industry. PMID:16177683

    Reese, Ellen; DeVerteuil, Geoffrey; Thach, Leanne

    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. PMID:20827846

    The K6G unit of Los Angeles Men's Central Jail is comprised of males who have sex with males (MSM), whether gay, bisexual, or transgender. Within this unit, condoms are distributed to inmates, one condom per week. The current study was conducted to better understand the experiences and opinions of jail staff as they pertain to the condom distribution program's effectiveness and impact on jail safety and management. A total of 10 staff interviews were conducted with the unit's line staff (n = 8) and administrative personnel (n = 2). Findings suggest that despite the contradictory "mixed message" that jail staff felt the program sent, it causes few operational or safety concerns and is perceived to be beneficial to public health.

    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.

    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.

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

    Science.gov (United States)

    Wu, Hao; Papoian, Garegin; Papoian Theoretical Biophysics Group Team

    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.

    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. PMID:27640160

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

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

    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.

    2015-12-01

    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.

  15. Going beyond clustering in MD trajectory analysis: an application to villin headpiece folding.

    Directory of Open Access Journals (Sweden)

    Aruna Rajan

    Full Text Available Recent advances in computing technology have enabled microsecond long all-atom molecular dynamics (MD simulations of biological systems. Methods that can distill the salient features of such large trajectories are now urgently needed. Conventional clustering methods used to analyze MD trajectories suffer from various setbacks, namely (i they are not data driven, (ii they are unstable to noise and changes in cut-off parameters such as cluster radius and cluster number, and (iii they do not reduce the dimensionality of the trajectories, and hence are unsuitable for finding collective coordinates. We advocate the application of principal component analysis (PCA and a non-metric multidimensional scaling (nMDS method to reduce MD trajectories and overcome the drawbacks of clustering. To illustrate the superiority of nMDS over other methods in reducing data and reproducing salient features, we analyze three complete villin headpiece folding trajectories. Our analysis suggests that the folding process of the villin headpiece is structurally heterogeneous.

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

    Science.gov (United States)

    Manago, K. F.; Hogue, T. S.

    2015-12-01

    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

    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.

  3. Mapping CH4 : CO2 ratios in Los Angeles with CLARS-FTS from Mount Wilson, California

    Directory of Open Access Journals (Sweden)

    K. W. Wong

    2014-06-01

    Full Text Available The Los Angeles megacity, which is home to more than 40% of the population in California, is the second largest megacity in the United States and an intense source of anthropogenic greenhouse gases (GHGs. Quantifying GHG emissions from the megacity and monitoring their spatiotemporal trends are essential to be able to understand the effectiveness of emission control policies. Here we measure carbon dioxide (CO2 and methane (CH4 across the Los Angeles megacity using a novel approach – ground-based remote sensing from a mountaintop site. A Fourier Transform Spectrometer (FTS with agile pointing optics, located on Mount Wilson at 1.67 km above sea level, measures reflected near infrared sunlight from 29 different surface targets on Mount Wilson and in the Los Angeles megacity to retrieve the slant column abundances of CO2, CH4 and other trace gases above and below Mount Wilson. This technique provides persistent space and time resolved observations of path-averaged dry-air GHG concentrations, XGHG, in the Los Angeles megacity and simulates observations from a geostationary satellite. In this study, we combined high sensitivity measurements from the FTS and the panorama from Mount Wilson to characterize anthropogenic CH4 emissions in the megacity using tracer : tracer correlations. During the period between September 2011 and October 2013, the observed XCH4 : XCO2 excess ratio, assigned to anthropogenic activities, varied from 5.4 to 7.3 ppb CH4 (ppm CO2−1, with an average of 6.4 ± 0.5 ppb CH4 (ppm CO2−1 compared to the value of 4.6 ± 0.9 ppb CH4 (ppm CO2−1 expected from the California Air Resources Board (CARB bottom-up emission inventory. Persistent elevated XCH4 : XCO2 excess ratios were observed in Pasadena and in the eastern Los Angeles megacity. Using the FTS observations on Mount Wilson and the bottom-up CO2 emission inventory, we derived a top-down CH4 emission of 0.39± 0.06 Tg CH4 year−1 in the Los Angeles megacity. This is 18

  5. 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

    The landscape of combined baccalaureate-MD programs has changed substantially in the last two decades but has not been documented in detail. The authors review the current state of these programs and discuss opportunities for future study of their evolving role and potential impact.In 2011, using a definition of baccalaureate-MD program built on prior research, the authors reviewed Association of American Medical Colleges sources and medical school Web sites to identify and characterize 81 active programs. In addition, they surveyed the 57 medical schools offering those programs; 31 schools with 39 programs responded. The resulting database inventories the number and distribution of programs; institutional affiliations; missions or goals; length; size; admissions criteria; curricula; and retention requirements.Since the inception of combined programs in 1961, their number and curricular length have increased. Pressures that spurred earlier programs remain evident in the goals of today's programs: attract talented high school or early college students, especially from diverse backgrounds; prepare physicians to meet societal needs; and offer an enriched premedical environment. Baccalaureate educational activities achieve program goals through special courses, medical experiences, community service, and learning communities tailored to students' needs. Admission and retention criteria are comparable to those of traditional medical schools.Combined baccalaureate-MD programs have evolved along several paths during the last half century and have enriched the baccalaureate experiences of medical students. Shifting expectations for the selection and education of future physicians warrant focused research on these programs to document their effectiveness in addressing those expectations. PMID:23018320

    Leadership skills are essential for a successful career as a physician-scientist, yet many MD-PhD training programs do not offer formal training in leadership. The Vanderbilt Medical Scientist Training Program (MSTP) previously established a 2-day leadership workshop that has been held biennially since 2006 for students in the first and second years of the graduate school portion of combined MD and PhD training (G1/G2 students). Workshop attendees have consistently rated this workshop as a highly effective experience. However, opportunities for structured training in leadership competencies during the subsequent 3-5 years of MD-PhD training are limited. Given the success of the G1/G2 leadership workshop and the need for continuity in this model of leadership training, we developed a half-day workshop for MSTP students in the clinical years of medical school (M3/M4 students) to foster continued training in leadership. Our workshop curriculum, based in part on original cases drafted by Vanderbilt MSTP students, provides concrete strategies to manage conflict and navigate leadership transitions in the physician-scientist career path. The curriculum emphasizes both short-term competencies, such as effective participation as a member of a clinical team, and long-term competencies, such as leadership of a research team, division, or department. Our inaugural senior leadership workshop, held in August, 2015, was judged by student participants to be well organized and highly relevant to leadership concepts and skills. It will be offered biennially in our training curriculum for M3 and M4 MSTP students. PMID:27499363

  8. Understanding the mechanism of LCST phase separation of mixed ionic liquids in water by MD simulations.

    Recently, it has been found experimentally that two different amino acid ionic liquids (ILs) can be mixed to show unique lowest critical solution temperature (LCST) phase separation in water. However, little is known about the mechanism of phase separation in these IL/water mixtures at the molecular level. In this work, five kinds of amino acid ILs were chosen to study the mechanism of LCST-type phase separation by molecular dynamics (MD) simulations. Toward this end, a series of all-atom MD simulations were carried out on the ternary mixtures consisting of two different ILs and water at different temperatures. The various interaction energies and radial distribution functions (RDFs) were calculated and analyzed for these mixed systems. It was found that for amino acid ILs, the -NH2 or -COOH group of one anion could have a hydrogen bonding interaction with the -COO(-) group of another anion. With the increase of temperature, this kind of hydrogen bonding interaction between anions was strengthened and then the anion-H2O electrostatic interaction was weakened, which led to the LCST-type phase separation of the mixed ILs in water. In addition, a series of MD simulations for [P6668]1[Lys]n[Asp]1-n/H2O systems were also performed to study the effect of the mixing ratio of ILs on phase separation. It was also noted that the experimental critical composition corresponding to the lowest critical solution temperature was well predicted from the total electrostatic interaction energies as a function of mole fraction of [P6668][Lys] in these systems. The conclusions drawn from this study may provide new insight into the LCST-type phase behavior of ILs in water, and motivate further studies on practical applications. PMID:27498928

  9. 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

    same time, theoretical and computational approaches gain in reliability and their field of application widens. In this short paper, we discuss recent advances in the areas of solution nuclear magnetic resonance (NMR spectroscopy and molecular dynamics (MD simulations that were made possible by the combination of both methods, that is, through their synergistic use. We present the main NMR observables and parameters that can be computed from simulations, and how they are used in a variety of complementary applications, including dynamics studies, model-free analysis, force field validation, and structural studies.

    2016-01-01

    Leadership skills are essential for a successful career as a physician-scientist, yet many MD–PhD training programs do not offer formal training in leadership. The Vanderbilt Medical Scientist Training Program (MSTP) previously established a 2-day leadership workshop that has been held biennially since 2006 for students in the first and second years of the graduate school portion of combined MD and PhD training (G1/G2 students). Workshop attendees have consistently rated this workshop as a hi...

  15. SN 2009md: Another faint supernova from a low mass progenitor

    We present adaptive optics imaging of the core collapse supernova (SN) 2009md, which we use together with archival \\emph{Hubble Space Telescope} data to identify a coincident progenitor candidate. We find the progenitor to have an absolute magnitude of $V = -4.63^{+0.3}_{-0.4}$ mag and a colour of $V-I = 2.29^{+0.25}_{-0.39}$ mag, corresponding to a progenitor luminosity of log $L$/L$_{\\odot}$ $\\sim4.54\\pm0.19$ dex. Using the stellar evolution code STARS, we find this to be consistent with a ...

  16. Neutron emission as a function of fragment energy in the spontaneous fission of 260Md

    International Nuclear Information System (INIS)

    The authors have made the first measurement of the number of neutrons emitted in the spontaneous fission of a nuclide in which very high fragment energies dominate the fission process. In bombardments of 254Es, they produced 28-d 260Md, which was neutron-counted in a 1-m-diam spherical tank containing a Gd-doped scintillator solution. The average number of neutrons emitted per fission is only 2.58 ± 0.11, substantially less than for other actinides. A direct correlation of neutron multiplicity with fragment excitation energy is clearly demonstrated

  17. The 25 March 1993 Scotts Mills, Oregon, earthquake and aftershock sequence: Spatial distribution, focal mechanisms, and the mount angel fault

    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.

    The objective of this paper is to address the problems of inefficiency and inequity in water allocation in the El Angel watershed, located in Ecuador's Sierra region. Water is captured in a high-altitude region of the watershed and distributed downstream to producers in four elevation-defined zones via a system of canals. Upstream and downstream producers face radically different conditions with respect to climate and terrain. A mathematical programming model was created to study the conseque...

    2014-01-01

    This dissertation provides a new perspective to apply in the study of metropolitan development at the turn of 20th Century America. It reveals a group of entrepreneurial men whose collective contribution to the real estate industry had just as much to do with shaping urban spaces as the wealthy, more established, and power-wielding elites that are often credited with such development. Los Angeles is the case study of the dissertation because it underwent such a dramatic transformation durin...
