Binétruy, Pierre

2016-01-01

Nous sommes habitués à observer la lumière des étoiles pour comprendre l’Univers. Ce n’est pourtant pas la radiation la plus présente dans l’Univers mais c’est celle que nous avons d’abord identifiée car nos yeux sont des « détecteurs de lumière ». Or l’Univers est mu par la gravité, non par la lumière. C’est donc la radiation associée, appelée onde gravitationnelle, qui est de première importance pour comprendre le fonctionnement de l’Univers. La détection des ondes gravitationnelles annoncée le 11 février 2016, par le détecteur américain Ligo, a fait l'effet d'une bombe dans les médias. Ce livre, rédigé par un acteur important de cette physique de pointe, nous décrit cet étrange univers gravitationnel qui s'ouvre à nous.

This report presents the essential features and highlights of the 1998 Summer Faculty Fellowship Program at Ames Research Center and Dryden Flight Research Center in a comprehensive and concise form. Summary reports describing the fellows' technical accomplishments are enclosed in the attached technical report. The proposal for the 1999 NASA-ASEE-Stanford Summer Faculty Fellowship Program is being submitted under separate cover. Of the 31 participating fellows, 27 were at Ames and 4 were at Dryden. The Program's central feature is the active participation by each fellow in one of the key technical activities currently under way at either the NASA Ames Research Center or the NASA Dryden Flight Research Center. The research topic is carefully chosen in advance to satisfy the criteria of: (1) importance to NASA, (2) high technical level, and (3) a good match to the interests, ability, and experience of the fellow, with the implied possibility of NASA-supported follow-on work at the fellow's home institution. Other features of the Summer Faculty Fellowship Program include participation by the fellows in workshops and seminars at Stanford, the Ames Research Center, and other off-site locations. These enrichment programs take place either directly or remotely, via the Stanford Center for Professional Development, and also involve specific interactions between fellows and Stanford faculty on technical and other academic subjects. A few, brief remarks are in order to summarize the fellows' opinions of the summer program. It is noteworthy that 90% of the fellows gave the NASA-Ames/Dryden- Stanford program an "excellent" rating and the remaining 10%, "good." Also, 100% would recommend the program to their colleagues as an effective means of furthering their professional development as teachers and researchers. Last, but not least, 87% of the fellows stated that a continuing research relationship with their NASA colleagues' organization probably would be maintained. Therefore

Nonetheless, limited evidence exists about successful service-learning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students' attitudes about population health, highlights the program’s outcomes, and summarizes the lessons learned. This article suggests that Flu Crew is an example of one viable service-learning modality that supports influenza vaccinations in nonclinical settings while simultaneously benefiting future clinicians.

Comment fonctionne l’Univers ? Ce que le LHC peut nous apprendre

CERN. Geneva

2008-01-01

L'Univers en son enfance était une "soupe" de particules, de plus en plus chaudes (de plus haute énergie) à mesure qu'on remonte vers sa naissance, le "big bang". C'est ainsi que les observations à des énergies de plus en plus élevées nous permettent, par exemple, de nous approcher de plus près de la prime jeunesse de l'Univers et, donc, de mieux le comprendre. L'étude du macro- et du micro-cosme sont une science unique dans laquelle, de façon surprenante, ce que nous comprenons le moins bien est le vide, qui ne semble pas l'être: il existe une différence fondamentale entre le vide et le néant. Le LHC pourrait nous permettre de voir les vibrations de la "substance" du vide, qu'on appelle les particules 'de Higgs'.

2018-01-01

Abstract Rationale: To apply thoracic endovascular aortic repair (TEVAR) to treat dwarfism complicated with Stanford B aortic dissection. Patient concerns: In this report, we presented a 63-year-old male patient of dwarfism complicated with Stanford B aortic dissection successfully treated with TEVAR. Diagnoses: He was diagnosed with dwarfism complicated with Stanford B aortic dissection. Interventions: After conservative treatment, the male patient underwent TEVAR at 1 week after hospitalization. After operation, he presented with numbness and weakness of his bilateral lower extremities, and these symptoms were significantly mitigated after effective treatment. At 1- and 3-week after TEVAR, the aorta status was maintained stable and restored. Outcomes: The patient obtained favorable clinical prognosis and was smoothly discharged. During subsequent follow-up, he remained physically stable. Lessons: TEVAR is probably an option for treating dwarfism complicated with Stanford B aortic dissection, which remains to be validated by subsequent studies with larger sample size. PMID:29703033

LIONs at the Stanford Linear Accelerator Center

International Nuclear Information System (INIS)

Constant, T.N.; Zdarko, R.W.; Simmons, R.H.; Bennett, B.M.

1998-01-01

The term LION is an acronym for Long Ionization Chamber. This is a distributed ion chamber which is used to monitor secondary ionization along the shield walls of a beam line resulting from incorrectly steered charged particle beams in lieu of the use of many discrete ion chambers. A cone of ionizing radiation emanating from a point source as a result of incorrect steering intercepts a portion of 1-5/8 inch Heliax cable (about 100 meters in length) filled with Argon gas at 20 psi and induces a pulsed current which is proportional to the ionizing charge. This signal is transmitted via the cable to an integrator circuit whose output is directed to an electronic comparators, which in turn is used to turn off the accelerated primary beam when preset limits are exceeded. This device is used in the Stanford Linear Accelerator Center (SLAC) Beam Containment System (BCS) to prevent potentially hazardous ionizing radiation resulting from incorrectly steered beams in areas that might be occupied by people. This paper describes the design parameters and experience in use in the Final Focus Test Beam (FFTB) area of the Stanford Linear Accelerator Center

2016-06-01

Chronic disease self-management is a priority in health care. Personal and environmental barriers for populations with neuromuscular disorders might diminish the efficacy of self-management programs, although they have been shown to be an effective intervention in many populations. Owing to their occupational expertise, occupational therapists might optimize self-management program interventions. This study aimed to adapt the Stanford Chronic Disease Self-Management Program (CDSMP) for people with myotonic dystrophy type 1 (DM1) and assess its acceptability and feasibility in this population. Using an adapted version of the Stanford CDSMP, a descriptive pilot study was conducted with 10 participants (five adults with DM1 and their caregivers). A semi-structured interview and questionnaires were used. The Stanford CDSMP is acceptable and feasible for individuals with DM1. However, improvements are required, such as the involvement of occupational therapists to help foster concrete utilization of self-management strategies into day-to-day tasks using their expertise in enabling occupation. Although adaptations are needed, the Stanford CDSMP remains a relevant intervention with populations requiring the application of self-management strategies. © CAOT 2016.

All-in-one 3D printed microscopy chamber for multidimensional imaging, the UniverSlide

2017-02-01

While live 3D high resolution microscopy techniques are developing rapidly, their use for biological applications is partially hampered by practical difficulties such as the lack of a versatile sample chamber. Here, we propose the design of a multi-usage observation chamber adapted for live 3D bio-imaging. We show the usefulness and practicality of this chamber, which we named the UniverSlide, for live imaging of two case examples, namely multicellular systems encapsulated in sub-millimeter hydrogel shells and zebrafish larvae. We also demonstrate its versatility and compatibility with all microscopy devices by using upright or inverted microscope configurations after loading the UniverSlide with fixed or living samples. Further, the device is applicable for medium/high throughput screening and automatized multi-position image acquisition, providing a constraint-free but stable and parallelized immobilization of the samples. The frame of the UniverSlide is fabricated using a stereolithography 3D printer, has the size of a microscopy slide, is autoclavable and sealed with a removable lid, which makes it suitable for use in a controlled culture environment. We describe in details how to build this chamber and we provide all the files necessary to print the different pieces in the lab.

Kitts, Christopher A.; Twiggs, Robert J.

1995-01-01

Stanford University's Department of Aeronautics and Astronautics has commenced full scale development of a new microsatellite initiative. Known as the satellite quick research testbed (SQUIRT) program, the project's goal is to produce student engineered satellites capable of servicing state-of-the-art research payloads on a yearly basis. This program is specifically designed to meet the education and research goals of the department's Satellite Systems Development Laboratory. SQUIRT vehicles are envisioned to consist of a 25 pound, 9 inch tall, 16 inch diameter hexagonal structure with complete processor, communications, power, thermal, and attitude subsystems. These spacecraft cater to low power, volume, and mass research experiments and student developed educational packages. Mission lifetimes of up to one year are considered. Through student participation, voluntary mentoring from the academic and industrial communities, and the extensive use of off-the-shelf components, the cash outlay target for SQUIRT class vehicles is $50,000. This paper discusses the educational and research issues surrounding the development of Stanford's spacecraft design curriculum and the formulation of the SQUIRT program. A technical review of the first SQUIRT satellite, named SAPPHIRE, and an outline of the conceptual plans for other missions is also presented. Additionally, initiatives concerning partner academic institutions and public domain design information are featured.

The Stanford Synchrotron Radiation Laboratory, 20 years of synchrotron light

International Nuclear Information System (INIS)

Cantwell, K.

1993-08-01

The Stanford Synchrotron Radiation Laboratory (SSRL) is now operating as a fully dedicated light source with low emittance electron optics, delivering high brightness photon beams to 25 experimental stations six to seven months per year. On October 1, 1993 SSRL became a Division of the Stanford Linear Accelerator Center, rather than an Independent Laboratory of Stanford University, so that high energy physics and synchrotron radiation now function under a single DOE contract. The SSRL division of SLAC has responsibility for operating, maintaining and improving the SPEAR accelerator complex, which includes the storage ring and a 3 GeV injector. SSRL has thirteen x-ray stations and twelve VUV/Soft x-ray stations serving its 600 users. Recently opened to users is a new spherical grating monochromator (SGM) and a multiundulator beam line. Circularly polarized capabilities are being exploited on a second SGM line. New YB 66 crystals installed in a vacuum double-crystal monochromator line have sparked new interest for Al and Mg edge studies. One of the most heavily subscribed stations is the rotation camera, which has been recently enhanced with a MAR imaging plate detector system for protein crystallography on a multipole wiggler. Under construction is a new wiggler-based structural molecular biology beam line with experimental stations for crystallography, small angle scattering and x-ray absorption spectroscopy. Plans for new developments include wiggler beam lines and associated facilities specialized for environmental research and materials processing

Optimization on Trajectory of Stanford Manipulator based on Genetic Algorithm

Directory of Open Access Journals (Sweden)

Han Xi

2017-01-01

Full Text Available The optimization of robot manipulator’s trajectory has become a hot topic in academic and industrial fields. In this paper, a method for minimizing the moving distance of robot manipulators is presented. The Stanford Manipulator is used as the research object and the inverse kinematics model is established with Denavit-Hartenberg method. Base on the initial posture matrix, the inverse kinematics model is used to find the initial state of each joint. In accordance with the given beginning moment, cubic polynomial interpolation is applied to each joint variable and the positive kinematic model is used to calculate the moving distance of end effector. Genetic algorithm is used to optimize the sequential order of each joint and the time difference between different starting time of joints. Numerical applications involving a Stanford manipulator are presented.

Stanford-Binet & WAIS IQ Differences and Their Implications for Adults with Intellectual Disability (aka Mental Retardation).

Silverman, Wayne; Miezejeski, Charles; Ryan, Robert; Zigman, Warren; Krinsky-McHale, Sharon; Urv, Tiina

2010-03-01

Stanford-Binet and Wechsler Adult Intelligence Scale (WAIS) IQs were compared for a group of 74 adults with intellectual disability (ID). In every case, WAIS Full Scale IQ was higher than the Stanford-Binet Composite IQ, with a mean difference of 16.7 points. These differences did not appear to be due to the lower minimum possible score for the Stanford-Binet. Additional comparisons with other measures suggested that the WAIS might systematically underestimate severity of intellectual impairment. Implications of these findings are discussed regarding determination of disability status, estimating prevalence of ID, assessing dementia and aging-related cognitive declines, and diagnosis of ID in forensic cases involving a possible death penalty.

To apply thoracic endovascular aortic repair (TEVAR) to treat dwarfism complicated with Stanford B aortic dissection. In this report, we presented a 63-year-old male patient of dwarfism complicated with Stanford B aortic dissection successfully treated with TEVAR. He was diagnosed with dwarfism complicated with Stanford B aortic dissection. After conservative treatment, the male patient underwent TEVAR at 1 week after hospitalization. After operation, he presented with numbness and weakness of his bilateral lower extremities, and these symptoms were significantly mitigated after effective treatment. At 1- and 3-week after TEVAR, the aorta status was maintained stable and restored. The patient obtained favorable clinical prognosis and was smoothly discharged. During subsequent follow-up, he remained physically stable. TEVAR is probably an option for treating dwarfism complicated with Stanford B aortic dissection, which remains to be validated by subsequent studies with larger sample size.

Deynes-Exclusa, Yazmin; Sayers-Montalvo, Sean K; Martinez-Taboas, Alfonso

2011-04-01

The only hypnotizability scale that has been translated and validated for the Puerto Rican population is the Barber Suggestibility Scale (BSS). In this article, the Stanford Hypnotic Clinical Scale (SHCS) was translated and validated for this population. The translated SHCS ("Escala Stanford de Hipnosis Clinica" [ESHC]) was administered individually to 100 Puerto Rican college students. There were no significant differences found between the norms of the original SHCS samples and the Spanish version of the SHCS. Both samples showed similar distributions. The Spanish version's internal reliability as well as the item discrimination index were adequate. The authors conclude that the ESHC is an adequate instrument to measure hypnotizability in the Puerto Rican population.

2005-05-01

The Stanford Solar Observatories Group and Haas Center for Public Service have created an innovative model for scientist-educator partnerships in which science students are trained and mentored by public service education professionals to create outreach events for local communities. The program, Science in Service, is part of the EPO plan for the Solar Group's participation in NASA's Solar Dynamics Observatory mission. Based on the principles of service learning, the Science in Service Program mentors college science students in best practices for communicating science and engages these students in public service projects that center on teaching solar science. The program goals are to - Enhance and expand the learning experiences that pre-college students, from underserved and underrepresented groups in particular, have in science and technology. - Promote leadership in community service in the area of science and engineering among the next generation of scientists and engineers, today's undergraduate students. - Encourage science and engineering faculty to think creatively about their outreach requirements and to create a community of faculty committed to quality outreach programs. This talk will describe the unique advantages and challenges of a research-public service partnership, explain the structure of Stanford's Science in Service Program, and present the experiences of the undergraduates and the outreach communities that have been involved in the program.

Objective: To investigate the value of bedside echocardiography in diagnosis and risk assessment of in-hospital death of patients with Stanford type A aortic dissection. Methods: The clinical data of 229 patients with Stanford type A aortic dissection diagnosed by CT angiography in Zhongshan Hospital affiliated to Fudan University between January 2009 and January 2016 were retrospectively analyzed. The patients were divided into survival group(191 cases)and non-survival group(38 cases)according to presence or absence of in-hospital death. The bedside echocardiography features were analyzed, and influence factors of in-hospital death were determined by multivariate logistic regression analysis. Results: (1) Compared with the survival group, the non-survival group had lower surgery rate (60.52%(23/38) vs. 85.34%(163/191), P 0.05). (2) The bedside echocardiography results showed that prevalence of aortic valve involvement(65.79%(25/38) vs.34.03%(65/191), P 0.05). (3) The multivariate logistic regression analysis showed that aortic valve involvement( OR =3.275, 95% CI 1.290-8.313, P risk factors for in-hospital death in patients with Stanford type A aortic dissection. Conclusions: Bedside echocardiography has significant diagnostic value for Stanford type A aortic dissection. Aortic valve involvement, enlargement of aortic root diameter and without surgery are independent risk factors for patients with Stanford type A aortic dissection.

The Stanford Linear Collider

Emma, P.

The Stanford Linear Collider (SLC) is the first and only high-energy e + e - linear collider in the world. Its most remarkable features are high intensity, submicron sized, polarized (e - ) beams at a single interaction point. The main challenges posed by these unique characteristics include machine-wide emittance preservation, consistent high intensity operation, polarized electron production and transport, and the achievement of a high degree of beam stability on all time scales. In addition to serving as an important machine for the study of Z 0 boson production and decay using polarized beams, the SLC is also an indispensable source of hands-on experience for future linear colliders. Each new year of operation has been highlighted with a marked improvement in performance. The most significant improvements for the 1994-95 run include new low impedance vacuum chambers for the damping rings, an upgrade to the optics and diagnostics of the final focus systems, and a higher degree of polarization from the electron source. As a result, the average luminosity has nearly doubled over the previous year with peaks approaching 10 30 cm -2 s -1 and an 80% electron polarization at the interaction point. These developments as well as the remaining identifiable performance limitations will be discussed

The Stanford Relativity Gyroscope Experiment constitutes a fundamental test of Einstein's General Theory of Relativity, probing such heretofore untested aspects of the theory as those that relate to spin by means of drag-free satellite-borne gyroscopes. General Relativity's prediction of two orthogonal precessions (motional and geodetic) for a perfect Newtonian gyroscope in polar orbit has not yet been experimentally assessed, and will mark a significant advancement in experimental gravitation. The technology employed in the experiment has been under development for 25 years at NASA's Marshall Space Flight Center. Four fused quartz gyroscopes will be used.

L'univers des particules une introduction

2017-01-01

Au début du XXe siècle, les scientifiques imaginaient que l'ensemble du monde était construit à partir de trois "particules élémentaires" (électron, proton, photon). Depuis, nous avons appris que notre univers contient un nombre considérable de particules - soit des corps individualisés d'extension réduite - de natures et de caractéristiques très diverses, qu'il serait illusoire de chercher à énumérer de manière formelle et systématique. C'est pourquoi le propos de ce livre suit une stratégie fondamentalement différente. Il s'organise autour de certaines propriétés générales que laissent apparaître l'observation et l'étude des particules dans leur existence et leur conduite primaire. Aussi, chacune des parties de cet ouvrage rassemble plusieurs chapitres de thèmes voisins, mais un sujet donné peut également être traité en divers endroits et, de ce fait, être abordé sous différents angles de manière complémentaire.

The Stanford Automated Mounter: Enabling High-Throughput Protein Crystal Screening at SSRL

International Nuclear Information System (INIS)

Smith, C.A.; Cohen, A.E.

2009-01-01

The macromolecular crystallography experiment lends itself perfectly to high-throughput technologies. The initial steps including the expression, purification, and crystallization of protein crystals, along with some of the later steps involving data processing and structure determination have all been automated to the point where some of the last remaining bottlenecks in the process have been crystal mounting, crystal screening, and data collection. At the Stanford Synchrotron Radiation Laboratory, a National User Facility that provides extremely brilliant X-ray photon beams for use in materials science, environmental science, and structural biology research, the incorporation of advanced robotics has enabled crystals to be screened in a true high-throughput fashion, thus dramatically accelerating the final steps. Up to 288 frozen crystals can be mounted by the beamline robot (the Stanford Auto-Mounting System) and screened for diffraction quality in a matter of hours without intervention. The best quality crystals can then be remounted for the collection of complete X-ray diffraction data sets. Furthermore, the entire screening and data collection experiment can be controlled from the experimenter's home laboratory by means of advanced software tools that enable network-based control of the highly automated beamlines.

Rethinking the Relationship Between Academia and Industry: Qualitative Case Studies of MIT and Stanford.

Science.gov (United States)

Zhu, Fengliang; Hawk, Soaring

2016-10-01

As knowledge has become more closely tied to economic development, the interrelationship between academia and industry has become stronger. The result has been the emergence of what Slaughter and Leslie call academic capitalism. Inevitably, tensions between academia and industry arise; however, universities such as MIT and Stanford with long traditions of industry interaction have been able to achieve a balance between academic and market values. This paper describes the strategies adopted by MIT and Stanford to achieve this balance. The results indicate that implicit culture is a stronger determinant of balance than are explicit rules. Finally, the author proposes a concept of balance to reconsider the relationship between academia and industry: today's universities, particularly those with strengths in engineering and management, are both symbiotic and interdependent with industry. A reasonable attitude toward the university-industry relationship is that of balance rather than strict separation. Universities can thus establish effective mechanisms to reach a balance between conflicting values.

We describe two programs, Cal-Bridge and CAMPARE, with the common mission of increasing participation of groups traditionally underrepresented in astronomy, through summer research opportunities, in the case of CAMPARE, scholarships in the case of Cal-Bridge, and significant mentoring in both programs, creating a national impact on their numbers successfully pursuing a PhD in the field. In 9 years, the CAMPARE program has sent 150 students, >80% from underrepresented groups, to conduct summer research at one of 14 major research institutions throughout the country. Of the CAMPARE scholars who have graduated with a Bachelor’s degree, almost two-thirds (65%) have completed or are pursuing graduate education in physics, astronomy, or a related field, at institutions including UCLA, UC Riverside, UC Irvine, UC Santa Barbara, USC, Stanford, Univ. of Arizona, Univ. of Washington, Univ. of Rochester, Michigan State Univ., Georgia Tech, Georgia State Univ., Kent State, Indiana Univ., Univ. of Oregon, Syracuse Univ., Montana State Univ., and the Fisk- Vanderbilt Master’s-to-PhD program. Now in its fourth year, the Cal-Bridge program is a CSU-UC Bridge program comprised of physics and astronomy faculty from 9 University of California (UC), 15 California State University (CSU), and more than 30 California Community College (CCC) campuses throughout California. In the first four years, 34 Cal-Bridge Scholars have been selected, including 22 Hispanic, 3 African-American and 13 women students, 10 of whom are from URM groups. Thirty (30) of the 34 Cal-Bridge Scholars are first generation college students. In the last three years, 17 of 21 Cal-Bridge Scholars have begun or been accepted PhD programs in physics or astronomy at top PhD programs nationally. Three (3) of these scholars have won NSF Graduate Research Fellowships; one more received an Honorable Mention. Once selected, Cal-Bridge Scholars benefit from substantial financial support, intensive, joint mentoring by CSU

Engineering aspects of the Stanford relativity gyro experiment

Everitt, C. W. F.; Debra, D. B.

1981-01-01

According to certain theoretical predictions, the Newtonian laws of motion must be corrected for the effect of a gravitational field. Schiff (1960) proposed an experiment which would demonstrate the effect predicted by Einstein's Theory of General Relativity on a gyroscope. The experiment has been under development at Stanford University since 1961. The requirements involved make it necessary that the test be performed in a satellite to take advantage of weightlessness in space. In a discussion of engineering developments related to the experiment, attention is given to the development of proportional helium thrusters, the simulation of the attitude control system, aspects of inner loop control, the mechanization of the two-loop attitude control system, the effects of helium slosh on spacecraft pointing, and the data instrumentation system.

2009-01-01

Purpose: to evaluate the detectability of the Adamkiewicz artery (AA) in patients with acute Stanford type A aortic dissections with multi-detector computed tomography (MDCT). Materials and Methods: 51 patients with Stanford type A dissection underwent contrast-enhanced 64-row MDCT of the entire aorta (collimation 64 x 0.625 mm; rotation time 0.4sec; 120kV; 300 mAs). The visualization of the AA, its origin, and whether it originated from the true or false lumen were analyzed using source and multiplanar reformation images. Results: a single anterior radicular artery that formed a hairpin turn constituting the anterior spinal artery was visualized in 36 (70%) patients. Thirty (83%) of these arteries originated from the left side, and 35 (97%) originated between the level T7 and L2. Twenty-three (64%) arteries originated from the true and 13 (36%) from the false lumen. Two AAs in the same patient were not observed. Conclusion: MDCT depicts the AA in a high percentage of patients with acute Stanford type A aortic dissection. (orig.)

STANFORD: Highly polarized SLC electron beams

International Nuclear Information System (INIS)

Anon.

1993-01-01

Full text: Using specialized photocathodes made with 'strained' gallium arsenide, physicists at the Stanford Linear Accelerator Center (SLAC) have generated electron beams with polarizations in excess of 60 percent a year ahead of schedule. Together with recent luminosity increases, this breakthrough will have a major impact on the physics output of the Stanford Linear Collider (SLC). Beam polarization was almost tripled using photocathodes in which a gallium arsenide layer was grown epitaxially over a substrate of gallium arsenide phosphide. The mismatch between these two layers deforms the crystal structure and removes a degeneracy in the valence band structure, permitting selective optical pumping of one unique spin state. Whereas conventional gallium arsenide photocathodes are limited to 50 percent polarization because of this degeneracy (and realistic cathodes fall substantially below this theoretical limit), such strained crystal lattices have the potential to yield polarizations close to 100 percent. Polarization enhancement with strained lattices was first demonstrated in 1991 by a SLAC/Wisconsin/ Berkeley group (May 1991, page 6) with a 71 percent polarization in a laboratory experiment. More recently this group has achieved polarization in excess of 90 percent, reported last November at the Nagoya Spin Symposium. (In a complementary development, a Japanese KEK/ Nagoya/KEK obtains polarized beams using a 'superlattice' - May 1991, page 4.) The 1993 SLC run, the strained gallium arsenide photocathode technique's debut in an operating particle accelerator, has proved to be a resounding, unqualified success - as have physics experiments on the Z particles produced by the highly polarized beam. A conservative approach was called for, due to concerns about possible charge saturation effects. A relatively thick (0.3 micron) gallium arsenide layer was used for the photocathode in the SLC polarized electron source. With a titanium

Theory and Development of Position-Sensitive Quantum Calorimeters. Degree awarded by Stanford Univ.

Figueroa-Feliciano, Enectali; White, Nicholas E. (Technical Monitor)

Quantum calorimeters are being developed as imaging spectrometers for future X-ray astrophysics observatories. Much of the science to be done by these instruments could benefit greatly from larger focal-plane coverage of the detector (without increasing pixel size). An order of magnitude more area will greatly increase the science throughput of these future instruments. One of the main deterrents to achieving this goal is the complexity of the readout schemes involved. We have devised a way to increase the number of pixels from the current baseline designs by an order of magnitude without increasing the number of channels required for readout. The instrument is a high energy resolution, distributed-readout imaging spectrometer called a Position-Sensitive Transition-Edge Sensor (POST). A POST is a quantum calorimeter consisting of two Transition-Edge Sensors (TESS) on the ends of a long absorber capable of one-dimensional imaging spectroscopy. Comparing rise time and energy information from the two TESS, the position of the event in the POST is determined. The energy of the event is inferred from the sum of the two pulses. We have developed a generalized theoretical formalism for distributed-readout calorimeters and apply it to our devices. We derive the noise theory and calculate the theoretical energy resolution of a POST. Our calculations show that a 7-pixel POST with 6 keV saturation energy can achieve 2.3 eV resolution, making this a competitive design for future quantum calorimeter instruments. For this thesis we fabricated 7- and 15-pixel POSTS using Mo/Au TESs and gold absorbers, and moved from concept drawings on scraps of napkins to a 32 eV energy resolution at 1.5 keV, 7-pixel POST calorimeter.

Electro-optic (EO) techniques are increasingly used for longitudinal bunch profile measurements. A bunch profile monitor, based on electro-optic spectral decoding(EOSD), has been developed and demonstrated on the CALIFES beam line at CERN. The EO response is analysed using a frequency domain description, and two methods for extraction of absolute Coulomb field strengths from the electron bunch are demonstrated. Measurements at field strengths up to 1.3 MV/m agree with the expectation based on independent charge measurements.

1997-01-01

In May 1997, the Chief Executive of BP, John Browne, delivered a speech on global climate change at Stanford University, California. A shortened version of the speech is presented. BP have accepted the possibility of a link between greenhouse gas emissions and climate change and are basing their policies on that acceptance. The company is committed to a step-by-step process, involving both action to develop solutions and continuing research to improve knowledge, that will balance the requirements of economic development and environmental protection. Five specific steps are outlined. These are: the monitoring and controlling of carbon dioxide emissions in all aspects of the company's operations increasing the level of support given to continuing scientific work on climate change; technology transfer and joint implementation with other parties to limit and reduce net emission levels; the development of alternative energy sources, in particular, solar power; contributing to the public policy debate in search of wider global answers to the problem.

Alignment of the stanford linear collider Arcs

International Nuclear Information System (INIS)

Pitthan, R.; Bell, B.; Friedsam, H.

1987-01-01

The alignment of the Arcs for the Stanford Linear Collider at SLAC has posed problems in accelerator survey and alignment not encountered before. These problems come less from the tight tolerances of 0.1 mm, although reaching such a tight statistically defined accuracy in a controlled manner is difficult enough, but from the absence of a common reference plane for the Arcs. Traditional circular accelerators, including HERA and LEP, have been designed in one plane referenced to local gravity. For the SLC Arcs no such single plane exists. Methods and concepts developed to solve these and other problems, connected with the unique design of SLC, range from the first use of satellites for accelerator alignment, use of electronic laser theodolites for placement of components, computer control of the manual adjustment process, complete automation of the data flow incorporating the most advanced concepts of geodesy, strict separation of survey and alignment, to linear principal component analysis for the final statistical smoothing of the mechanical components

Full Text Available This paper presents a partial analysis of an emblematic monument of the military architecture from al-Andalus. Although Gormaz has been mentioned many times as an example of the caliphate architecture, it still remains without a complete study using adequate methodology to identify the different phases of its construction. A new photogrammetric survey of the main gate is presented, and its structure and design composition rules used are both analysed. Furthermore, an issue never studied before is also examined: the remains from a previous fortress, built probably with mud walls, from which only the marks left on the structures dated to the 10th century have reached present times.Este artículo aborda el análisis parcial de un monumento emblemático de la arquitectura militar andalusí, muy citado como ejemplo de la arquitectura califal pero que aún hoy adolece de un estudio en profundidad y con metodología adecuada para identificar sus distintas fases. Se presenta una planimetría fotogramétrica nueva de su puerta, se analiza su estructura y los cánones compositivos que marcaron su diseño y se aborda un tema hasta ahora nunca observado como es la existencia de vestigios de una fortaleza anterior construida seguramente con tapias de tierra y de la que sólo ha llegado hasta nosotros la impronta que dejó en las estructuras del siglo X.

Wavelength and power stability of the Stanford infrared SCA/FEL operating with the TRW wiggler have been measured using a high-resolution spectrometer and an image dissector system. The image dissector is capable of reading the spectrum of every single micropulse at 12 MHz throughout a macropulse of up to 2 ms duration. The intrinsic wavelength and power stability of the SCA/FEL are found to be δλ/λ=0.035% and δP/P=18%. The use of a feedback control system to stabilize the wavelength, and an acousto-optic modulator for output power smoothing, improves the performance to δλ/λ=0.012% and δP/P=7%

Many national organizations call for medical students to receive more public health education in medical school. Nonetheless, limited evidence exists about successful servicelearning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students' attitudes about population health, highlights the program's outcomes, and summarizes the lessons learned. This article suggests that Flu Crew is an example of one viable service-learning modality that supports influenza vaccinations in nonclinical settings while simultaneously benefiting future clinicians.

We describe two programs, Cal-Bridge and CAMPARE, with the common mission of increasing participation of groups traditionally underrepresented in astronomy, through summer research opportunities, in the case of CAMPARE, scholarships in the case of Cal-Bridge, and significant mentoring in both programs, creating a national impact on their numbers successfully pursuing a PhD in the field.In 8 years, the CAMPARE program has sent 112 students, >80% from underrepresented groups, to conduct summer research at one of 14 major research institutions throughout the country. Of the CAMPARE scholars who have graduated with a Bachelor’s degree, almost two-thirds (65%) have completed or are pursuing graduate education in physics, astronomy, or a related field, at institutions including UCLA, UC Riverside, UC Irvine, UC Santa Barbara, USC, Stanford, Univ. of Arizona, Univ. of Washington, Univ. of Rochester, Michigan State Univ., Georgia Tech, Georgia State Univ., Kent State, Indiana Univ., Univ. of Oregon, Syracuse Univ., Montana State Univ., and the Fisk-Vanderbilt Master’s-to-PhD program.Now entering its fourth year, the Cal-Bridge program is a CSU-UC Bridge program comprised of >140 physics and astronomy faculty from 9 University of California (UC), 15 California State University (CSU), and 30 California Community College (CCC) campuses throughout California. In the first four years, 34 Cal-Bridge Scholars have been selected, including 22 Hispanic, 3 African-American and 13 women students, 10 of whom are from URM groups. Thirty (30) of the 34 Cal-Bridge Scholars are first generation college students. In the last two years, 11 of 13 Cal-Bridge Scholars have begun PhD programs in physics or astronomy at top PhD programs nationally. Three (3) of these 11 scholars have won NSF Graduate Research Fellowships; one more received an Honorable Mention.

Nevle, R. J.; Watson Nelson, T.; Harris, J. M.; Klemperer, S. L.

2012-12-01

In 2012, the School of Earth Sciences (SES) at Stanford University sponsored two summer undergraduate research programs. Here we describe these programs and efforts to build a cohesive research cohort among the programs' diverse participants. The two programs, the Stanford School of Earth Sciences Undergraduate Research (SESUR) Program and Stanford School of Earth Sciences Summer Undergraduate Research in Geoscience and Engineering (SURGE) Program, serve different undergraduate populations and have somewhat different objectives, but both provide students with opportunities to work on strongly mentored yet individualized research projects. In addition to research, enrichment activities co-sponsored by both programs support the development of community within the combined SES summer undergraduate research cohort. Over the course of 6 to 9 months, the SESUR Program engages Stanford undergraduates, primarily rising sophomores and juniors, with opportunities to deeply explore Earth sciences research while learning about diverse areas of inquiry within SES. Now in its eleventh year, the SESUR experience incorporates the breadth of the scientific endeavor: finding an advisor, proposal writing, obtaining funding, conducting research, and presenting results. Goals of the SESUR program include (1) providing a challenging and rewarding research experience for undergraduates who wish to explore the Earth sciences; (2) fostering interdisciplinary study in the Earth sciences among the undergraduate population; and (3) encouraging students to major or minor in the Earth sciences and/or to complete advanced undergraduate research in one of the departments or programs within SES. The SURGE Program, now in its second year, draws high performing students, primarily rising juniors and seniors, from 14 colleges and universities nationwide, including Stanford. Seventy percent of SURGE students are from racial/ethnic backgrounds underrepresented in STEM fields, and approximately one

1990-10-01

The front-end signal processing electronics for the drift-chambers of the Stanford Large Detector (SLD) at the Stanford Linear Collider is described. The system is implemented with printed-circuit boards which are shaped for direct mounting on the detector. Typically, a motherboard comprises 64 channels of transimpedance amplification and analog waveform sampling, A/D conversion, and associated control and readout circuitry. The loaded motherboard thus forms a processor which records low-level wave forms from 64 detector channels and transforms the information into a 64 k-byte serial data stream. In addition, the package performs calibration functions, measures leakage currents on the wires, and generates wire hit patterns for triggering purposes. The construction and operation of the electronic circuits utilizing monolithic, hybridized, and programmable components are discussed

2016-07-01

Full Text Available Introduction: Teledermatology has proven to be an effective means of providing dermatologic care. The existing research has primarily evaluated its usefulness in a consultative model. Few academic centers have evaluated a patient-initiated model, and direct-to-consumer services remain the subject of controversy. Stanford Health Care recently launched a direct-care, patient-initiated teledermatology pilot program. This article evaluates the viability and patient satisfaction with this service. Materials and Methods: During the pilot period, patients were able to seek remote dermatologic care using an eVisit tool in their MyHealth account. Patients initiated the consultation, answered questions regarding their complaint, and uploaded a picture if relevant. A Stanford dermatologist reviewed each eVisit and responded with an assessment and plan. The dermatologist noted whether they were able to make a diagnosis and their level of confidence in it. After the study, 10 patients participated in a focus group to provide feedback on the service. Results: In all, 38 patients sought care during the pilot period. A dermatologist was able to make a diagnosis in 36 of 38 (95% cases, with an average confidence level of 7.9 of 10. The average time to consultation was 0.8 days. Patients indicated high levels of satisfaction with the service although they had suggestions for improvement. Discussion: Patients provided clinically useful images and information in a direct-care teledermatology model. Such services allow dermatology providers to increase access while maintaining high-quality care in an academic medical center. Further research is needed on standalone services that cannot integrate encounters with the patient’s existing medical record.

Likelihood of women vs. men to receive bachelor's degrees in physics at Stanford, 1900-1929.

Science.gov (United States)

Nero, Anthony

2005-04-01

Work by K. Tolley indicates that girls in mid to late 19th century U.S. high schools were more likely to study mathematics and natural philosophy (i.e., physics and astronomy) than were boys (who pursued the classics).* She also found that after the turn of the century women were more likely than men to receive bachelor's degrees in math and biological sciences at Stanford, but her sampling of every fifth year yielded too few data to be conclusive about physics. Reexamination of graduation lists at Stanford, yielding data for each year from 1900 to 1929, shows that, while absolute numbers were small, women were as likely as men to receive bachelor's degrees in physics during the first decade of the century, in the second decade they were notably more likely, and in the third their likelihood decreased substantially, while that of men rose to exceed that of women. (Women were much more likely to receive bachelor's degrees in math, exceeding the likelihood for men by an order of magnitude during the second and third decades.) *K.

This paper combines observational data sets and cosmological simulations to generate realistic numerical replicas of the nearby Universe. The latter are excellent laboratories for studies of the non-linear process of structure formation in our neighbourhood. With measurements of radial peculiar velocities in the local Universe (cosmicflows-2) and a newly developed technique, we produce Constrained Local UniversE Simulations (CLUES). To assess the quality of these constrained simulations, we compare them with random simulations as well as with local observations. The cosmic variance, defined as the mean one-sigma scatter of cell-to-cell comparison between two fields, is significantly smaller for the constrained simulations than for the random simulations. Within the inner part of the box where most of the constraints are, the scatter is smaller by a factor of 2 to 3 on a 5 h-1 Mpc scale with respect to that found for random simulations. This one-sigma scatter obtained when comparing the simulated and the observation-reconstructed velocity fields is only 104 ± 4 km s-1, I.e. the linear theory threshold. These two results demonstrate that these simulations are in agreement with each other and with the observations of our neighbourhood. For the first time, simulations constrained with observational radial peculiar velocities resemble the local Universe up to a distance of 150 h-1 Mpc on a scale of a few tens of megaparsecs. When focusing on the inner part of the box, the resemblance with our cosmic neighbourhood extends to a few megaparsecs (<5 h-1 Mpc). The simulations provide a proper large-scale environment for studies of the formation of nearby objects.

User issues at the Stanford picosecond free electron laser center

International Nuclear Information System (INIS)

Smith, T.I.

1995-01-01

Assembling a productive user facility around a Free Electron Laser (FEL) is a complex task. Reliable operation of the FEL is a necessary, but by no means sufficient, condition to ensure that the center will be able to attract and keep the interest of first rate researchers. Some other issues which are important include: center wavelength stability and ease of tuning, bandwidth control, amplitude and position stability, ability to select arbitrary sequences of micropulses, and real time availability of information of the FEL's important parameters (spectral width, center wavelength, micropulse length and energy, etc.). In addition, at the Stanford Center we have found that providing additional systems (conventional picosecond lasers synchronized to the FEL, an FTIR spectrometer, a confocal microscopy, ...) has been important.

Positron--electron storage ring project: Stanford Linear Accelerator Center, Stanford, California. Final environmental statement

International Nuclear Information System (INIS)

1976-08-01

A final environmental statement is given which was prepared in compliance with the National Environmental Policy Act to support the Energy Research and Development Administration project to design and construct the positron-electron colliding beam storage ring (PEP) facilities at the Stanford Linear Accelerator Center (SLAC). The PEP storage ring will be constructed underground adjacent to the existing two-mile long SLAC particle accelerator to utilize its beam. The ring will be about 700 meters in diameter, buried at depths of 20 to 100 feet, and located at the eastern extremity of the SLAC site. Positron and electron beams will collide in the storage ring to provide higher energies and hence higher particle velocities than have been heretofore achieved. Some of the energy from the collisions is transformed back into matter and produces a variety of particles of immense interest to physicists. The environmental impacts during the estimated two and one-half years construction period will consist of movement of an estimated 320,000 cubic yards of earth and the creation of some rubble, refuse, and dust and noise which will be kept to a practical minimum through planned construction procedures. The terrain will be restored to very nearly its original conditions. Normal operation of the storage ring facility will not produce significant adverse environmental effects different from operation of the existing facilities and the addition of one water cooling tower. No overall increase in SLAC staff is anticipated for operation of the facility. Alternatives to the proposed project that were considered include: termination, postponement, other locations and construction of a conventional high energy accelerator

The Stanford-U.S. Geological Survey SHRIMP ion microprobe--a tool for micro-scale chemical and isotopic analysis

Bacon, Charles R.; Grove, Marty; Vazquez, Jorge A.; Coble, Matthew A.

2012-01-01

Answers to many questions in Earth science require chemical analysis of minute volumes of minerals, volcanic glass, or biological materials. Secondary Ion Mass Spectrometry (SIMS) is an extremely sensitive analytical method in which a 5–30 micrometer diameter "primary" beam of charged particles (ions) is focused on a region of a solid specimen to sputter secondary ions from 1–5 nanograms of the sample under high vacuum. The elemental abundances and isotopic ratios of these secondary ions are determined with a mass spectrometer. These results can be used for geochronology to determine the age of a region within a crystal thousands to billions of years old or to precisely measure trace abundances of chemical elements at concentrations as low as parts per billion. A partnership of the U.S. Geological Survey and the Stanford University School of Earth Sciences operates a large SIMS instrument, the Sensitive High-Resolution Ion Microprobe with Reverse Geometry (SHRIMP–RG) on the Stanford campus.

Allan Cox 1926”1987

Coe, Rob; Dalrymple, Brent

More than 1000 friends, students, and colleagues from all over the country filled Stanford Memorial Chapel (Stanford, Calif.) on February 3, 1987, to join in “A Celebration of the Life of Allan Cox.” Allan died early on the morning of January 27 while bicycling, the sport he had come to love the most. Between pieces of his favorite music by Bach and Mozart, Stanford administrators and colleagues spoke in tribute of Allan's unique qualities as friend, scientist, teacher, and dean of the School of Earth Sciences. James Rosse, Vice President and Provost of Stanford University, struck a particularly resonant chord with his personal remarks: "Allan reached out to each person he knew with the warmth and attention that can only come from deep respect and affection for others. I never heard him speak ill of others, and I do not believe he was capable of doing anything that would harm another being. He cared too much to intrude where he was not wanted, but his curiosity about people and the loving care with which he approached them broke down reserve to create remarkable friendships. His enthusiasm and good humor made him a welcome guest in the hearts of the hundreds of students and colleagues who shared the opportunity of knowing Allan Cox as a person."

Full Text Available RESUMEN: Aunque las primeras estrategias para evaluar la habilidad intelectual encuentran antecedentes milenarios en la antigua China, los intentos de medición en el periodo moderno comienzan con el psicólogo inglés Francis Galton en la década de 1880, mediante la aplicación de medidas fisiológicas para estimar el talento humano. A comienzos del siglo XX, los psicólogos franceses Alfred Binet y Théodore Simon construyeron las primeras escalas métricas para estimar la inteligencia de los niños. Estas fueron modificadas posteriormente en los Estados Unidos por Lewis Terman, quien publicó la revisión más conocida e influyente. En América Latina y otras regiones las adaptaciones locales se dieron en la misma época. En Paraguay, el test Stanford-Binet fue introducido en el decenio de 1920 por el maestro Ramón Indalecio Cardozo. Este no se limitó a una reproducción acrítica, sino que realizó algunas modificaciones para adaptarlo a las condiciones locales y mejorar la confiabilidad cultural de las pruebas. Este artículo estudia la introducción del test Stanford-Binet al contexto general de la educación paraguaya y los ajustes que llevó a cabo Cardozo. Para conseguirlo, se procede a una revisión de fuentes primarias y secundarias, colocando las ideas y los conceptos en el debido contexto histórico. También contribuye a ampliar otros trabajos anteriores centrados en la obra de este autor y en la psicología durante el periodo pre-universitario paraguayo.

In this presentation, I shall discuss the linear collider program at the Stanford Linear Accelerator Center as it is now, and as we hope to see it evolve over the next few years. Of greatest interest to the high energy accelerator physics community gathered here is the development of the linear collider concept, and so I shall concentrate most of this paper on a discussion of the present status and future evolution of the SLC. I will also briefly discuss the research and development program that we are carrying out aimed at the realization of the next generation of high-energy linear colliders. SLAC had a major colliding-beam storage-ring program as well, including present rings and design studies on future high-luminosity projects, but time constraints preclude a discussion of them. 8 figs., 3 tabs

We have measured the resonance parameters of the Z boson using 480 hadronic and Leptonic Z decays collected by the Mark II Detector at the Stanford Linear Collider. We find the Mass to be 91.14 ± 0.12 GeV/c 2 , and the width to be 2.42 +0.45 -0.35 GeV. If we constrain the visible width to its Standard Model value, we find a partial width to invisible decay modes corresponding to 2.8 ± 0.6 neutrino species with a 95% confidence level limit of 3.9. 9 refs., 1 fig., 4 tabs

Pulse-by-pulse energy measurement at the Stanford Linear Collider

International Nuclear Information System (INIS)

Blaylock, G.; Briggs, D.; Collins, B.; Petree, M.

1992-01-01

The stanford Linear Collider (SLC) collides a beam of electrons and positrons at 92 GeV. It is the first colliding linac, and produces Z 0 particles for High-Energy Physics measurements. The energy of each beam must be measured to one part in 10 4 on every collision (120 Hz). An Energy Spectrometer in each beam line after collision produces two stripes of high-energy synchrotron radiation with critical energy of a few MeV. The distance between these two stripes at an imaging plane measures the beam energy. The Wire- Imaging Synchrotron Radiation Detector (WISRD) system comprises a novel detector, data acquisition electronics, readout and analysis. The detector comprises an array of wires for each synchrotron stripe. The electronics measure secondary emission charge on each wire of each array. A Macintosh II (using THINK C, THINK Class Library) and DSP coprocessor (using ANSI C) acquire and analyze the data, and display and report the results for SLC operation

Alignment of the Stanford Linear Collider Arcs: Concepts and results

Pitthan, R.; Bell, B.; Friedsam, H.; Pietryka, M.; Oren, W.; Ruland, R.

1987-02-01

The alignment of the Arcs for the Stanford Linear Collider at SLAC has posed problems in accelerator survey and alignment not encountered before. These problems come less from the tight tolerances of 0.1 mm, although reaching such a tight statistically defined accuracy in a controlled manner is difficult enough, but from the absence of a common reference plane for the Arcs. Traditional circular accelerators, including HERA and LEP, have been designed in one plane referenced to local gravity. For the SLC Arcs no such single plane exists. Methods and concepts developed to solve these and other problems, connected with the unique design of SLC, range from the first use of satellites for accelerator alignment, use of electronic laser theodolites for placement of components, computer control of the manual adjustment process, complete automation of the data flow incorporating the most advanced concepts of geodesy, strict separation of survey and alignment, to linear principal component analysis for the final statistical smoothing of the mechanical components

Lobo, Viveta; Stromberg, Andrew Q; Rosston, Peter

2017-09-18

Point-of-care ultrasound is a critical component of graduate medical training in emergency medicine. Innovation in ultrasound teaching methods is greatly needed to keep up with a changing medical landscape. A field-wide trend promoting simulation and technology-enhanced learning is underway in an effort to improve patient care, as well as patient safety. In an effort to both motivate students and increase their skill retention, training methods are shifting towards a friendly competition model and are gaining popularity nationwide. In line with this emerging trend, Stanford incorporated the Sound Games - an educational ultrasound event with a distinctly competitive thread - within its existing two-day point-of-care ultrasound orientation course for emergency medicine interns. In this study, we demonstrate successful implementation of the orientation program, significant learning gains in participants, and overall student satisfaction with the course.

150-MW S-Band klystron program at the Stanford Linear Accelerator Center

Energy Technology Data Exchange (ETDEWEB)

Sprehn, D.; Caryotakis, G.; Phillips, R.M. [Stanford Linear Accelerator Center, Stanford Univ., Stanford, CA (United States)

1997-04-01

Two S-Band klystrons operating at 150 MW have been designed, fabricated and tested at the Stanford Linear Accelerator Center (SLAC) during the past two years for use in an experimental accelerator at Deutsches Elektronen Synchrotron (DESY) in Hamburg, Germany. Both klystrons operate at the design power, 60 Hz repetition rate, 3 {mu}s pulsewidth, with an efficiency > 40%, and agreement between the experimental results and simulations is excellent. The 535 kV, 700 A electron gun was tested by constructing a solenoidal focused beam-stick which identified a source of oscillation, subsequently engineered out of the klystron guns. Design of the beam-stick and the two klystrons is discussed, along with observation and suppression of spurious oscillations. Differences in design and the resulting performance of the klystrons is emphasized. (author)

Final Environmental Assessment for the construction and operation of an office building at the Stanford Linear Accelerator Center. Part 2

International Nuclear Information System (INIS)

1995-08-01

The Department of Energy (DOE) has prepared an Environmental Assessment (EA), DOE/EA-1107, analyzing the environmental effects relating to the construction and operation of an office building at the Stanford Linear Accelerator Center (SLAC). SLAC is a national facility operated by Stanford University, California, under contract with DOE. The center is dedicated to research in elementary particle physics and in those fields that make use of its synchrotron facilities. The objective for the construction and operation of an office building is to provide adequate office space for existing SLAC Waste Management (WM) personnel, so as to centralize WM personnel and to make WM operations more efficient and effective. Based on the analyses in the EA, the DOE has determined that the proposed action does not constitute a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act of 1969 (NEPA). Therefore, the preparation of an Environmental Impact Statement is not required. This report contains the Environmental Assessment, as well as the Finding of No Significant Impact (FONSI)

High Power Klystrons: Theory and Practice at the Stanford Linear Accelerator CenterPart I

Energy Technology Data Exchange (ETDEWEB)

Caryotakis, G.

2004-12-15

This is Part I of a two-part report on design and manufacturing methods used at SLAC to produce accelerator klystrons. Chapter 1 begins with the history and applications for klystrons, in both of which Stanford University was extensively involved. The remaining chapters review the theory of klystron operation, derive the principal formulae used in their design, and discuss the assumptions that they involve. These formulae are subsequently used in small-signal calculations of the frequency response of a particular klystron, whose performance is also simulated by two different computer codes. The results of calculations and simulations are compared to the actual performance of the klystron.

L'état de plasma le feu de l'Univers

Dans l'Antiquité, les Grecs considéraient que les constituants du monde dérivaient de quatre éléments essentiels : la terre, l'eau, l'air et le feu. Il n'est pas difficile de voir dans les trois premiers l'équivalent de nos états solide, liquide et gazeux. Mais l'état physique le plus répandu dans l'Univers - correspondant au feu des Anciens - n'est apparu que récemment et n'a été reconnu par la communauté des physiciens qu'en 1928 : c'est le plasma. Cet état très étrange - gazeux, électrique, lumineux, impalpable - reste le plus exotique et le plus inattendu. Il a donné naissance aux trois autres états puisque, à l'exception des éléments ultra-légers que sont l'hydrogène et l'hélium, tous ceux qui constituent notre monde (carbone, oxygène, fer, etc.) sont apparus dans ces fourneaux gigantesques, ces monstres de plasma, qu'étaient les premières étoiles.

2009-01-01

Empowerment evaluation was adopted by Stanford University's School of Medicine to engage in curricular reform. It was also used to prepare for an accreditation site visit. Empowerment evaluation is a guided form of self-evaluation. It was selected because the principles and practices of empowerment evaluation resonated with the collaborative and participatory nature of the curricular reform in the School. This article highlights one of the most important features of an empowerment evaluation:...

The high peak current polarized electron source of the Stanford Linear Collider

1994-01-01

The Stanford Linear Collider injector requires two 2 ns pulses of 4.5-5.5 x 10 10 electrons, separated by 61 ns at 120 Hz, from its source. Since 1992, these currents have been provided by a polarized electron source based on GaAs photocathodes. A beam polarization of 76±4% has been measured at the end of the 50 GeV linac. At low photocathode quantum efficiencies, and for excitation near threshold, the maximum current delivered by the source is constrained, not by the space charge limit of the gun, but by a ''charge limit'' of the photocathode. The charge limited current is proportional to the photocathode quantum efficiency, but the proportionality varies for different photocathode types. Experience with high polarization strained GaAs photocathodes on a test beamline and on the SLC is presented. (orig.)

Comparison of the LLL HANDYL76 code with three Stanford Linac experiments

Carson, J.K.

1976-06-01

HANDYL76, the Lawrence Livermore Laboratory version of SANDYL, the multidimensional Monte Carlo electron/photon computer code, was compared with experimental work performed on the Stanford Mark III Linear Accelerator. The three pieces of experimental work involved bombardment of Al, C, Cu, Sn, and Pb by using 185-MeV electrons, electron-induced cascade showers in Cu, Sn, and Pb at 900 MeV, and cascades in H 2 O and Al at 1 GeV. Agreement between experiment and code calculations were good for the 900-MeV work, but only the aluminum at 185 MeV was within associated uncertainties for the major part of the target. Although good agreement was attained at 1 GeV in aluminum, the H 2 O at 1 GeV produced moderate variations. Possible reasons for the differences obtained are discussed. 89 figures, 16 tables

Spin physics with polarized electrons at the SLC [Stanford Linear Collider

International Nuclear Information System (INIS)

Moffeit, K.C.

1990-11-01

The Stanford Linear Collider was designed to accommodate polarized electron beams. A gallium arsenide-based photon emission source will provide a beam of longitudinally polarized electrons of about 40 percent polarization. A system of bend magnets and a superconducting solenoid will be used to rotate the spins so that the polarization is preserved while the 1.21 GeV electrons are stored in the damping ring. Another set of bend magnets and two superconducting solenoids orient the spin vectors so that longitudinal polarization of the electrons is achieved at the collision point with the unpolarized positions. A system to monitor the polarization based on Moeller and Compton scattering will be used. Spin physics with longitudinally polarized electrons uses the measurement of the left-right asymmetry to provide tests of the Standard Model. The uncertainty in the measurement is precise enough to be sensitive to the effects of particles which can not be produced directly in the machines we have today. 5 refs

The calculated longitudinal impedance of the SLC [Stanford Linear Collider] damping rings

International Nuclear Information System (INIS)

Bane, K.L.F.

1988-05-01

A high level of current dependent bunch lengthening has been observed in the north damping ring of the Stanford Linear Collider (SLC), indicating that the ring's impedance is very inductive. This level of bunch lengthening will limit the performance of the SLC. In order to study the problem of bunch lengthening in the damping ring and the possibility of reducing their inductance we compute, in this report, the longitudinal impedance of the damping ring vacuum chamber. More specifically we find the response function of the ring to a short gaussian bunch. This function will later be used as a driving term in the longitudinal equation of motion. We also identify the important inductive elements of the vacuum chamber and estimate their contribution to the total ring inductance. This information will be useful in assessing the effect of vacuum chamber modifications. 7 refs. , 8 figs., 1 tab

Emerging from the Shadows: The Visual Arts and Asian American History

Full Text Available Asian American Art: A History, 1850-1970, the book from which this foreword is excerpted, is the first comprehensive study of the lives and artistic production of artists of Asian ancestry active in the United States before 1970. The publication features original essays by ten leading scholars, biographies of more than 150 artists, and over 400 reproductions of artwork, ephemera, and images of the artists. Aside from a few artists such as Dong Kingman, Yasuo Kuniyoshi, Isamu Noguchi, and Yun Gee, artists of Asian ancestry have received inadequate historical attention, even though many of them received wide critical acclaim during their productive years. This pioneering work recovers the extraordinarily impressive artistic production of numerous Asian Americans, and offers richly informed interpretations of a long-neglected art history. To unravel the complexity of Asian American art expression and its vital place in American art, the texts consider aesthetics, the social structures of art production and criticism, and national and international historical contexts. Without a doubt, Asian American Art will profoundly influence our understanding of the history of art in America and the Asian American experience for years to come.

Bunch lengthening in the SLC [Stanford Linear Collider] damping rings

International Nuclear Information System (INIS)

Bane, K.L.F.

1990-02-01

A high level of current dependent bunch lengthening has been observed on the North damping ring of the Stanford Linear Collider (SLC). At currents of 3 x 10 10 this behavior does not appear to degrade the machine's performance significantly. However, at the higher currents that are envisioned for the future one fears that its performance could be greatly degraded due to the phenomenon of bunch lengthening. This was the motivation for the work described in this paper. In this paper we calculate the longitudinal impedance of the damping ring vacuum chamber. More specifically, in this paper we find the response function of the ring to a short Gaussian bunch, which we call the Green function wake. In addition, we try to estimate the relative importance of the different vacuum chamber objects, in order to see how we might reduce the ring impedance. This paper also describes bunch length measurements performed on the North damping ring. We use the Green function wake, discussed above, to compute the bunch lengthening. Then we compare these results with those obtained from the measurements. In addition, we calculate the current dependence of the tune distribution

Objective: To assess the prophylactic measures of paraplegia and paralysis after endovascular graft exclusion (EVE) for Stanford B thoracic aortic dissections (TAD). Methods: The records of 116 consecutive patients undergoing endovascular TAD repair from 1998 to 2001 were retrospectively reviewed. Steroids were administrated postoperatively in high risk patients likely to be candidates for paraplegia or paralysis. Results: No paraplegia or paralysis occurred postoperatively in all cases, including the patient undergone selective spinal artery angiography (SSAA). Conclusions: Transluminal repair can avoid spinal cord ischemia due to aortic cross-clamping, there is still a risk of spinal cord injury caused by occlusion of intercostal arteries under the cover of endograft. A combination of the prophylactic measures, including SSAA and steroids, have been able to reduce the risk of paraplegia and paralysis. A graft-stent of appropriate length is the key point of this procedure

Top-Off Injection and Higher Currents at the Stanford Synchrotron Radiation Lightsource

Bauer, Johannes M.; Liu, James C.; Prinz, Alyssa A.; Rokni, Sayed H.; /SLAC

2011-04-05

The Stanford Synchrotron Radiation Lightsource (SSRL) at the SLAC National Accelerator Laboratory is a 234 m circumference storage ring for 3 GeV electrons with its synchrotron radiation serving currently 13 beamlines with about 27 experimental stations. It operated for long time with 100 mA peak current provided by usually three injections per day. In July 2009, the maximum beam current was raised to 200 mA. Over the period from June 2009 to March 2010, Top-Off operation started at every beamline. Top-Off, i.e., the injection of electrons into the storage ring with injection stoppers open, is necessary for SSRL to reach its design current of 500 mA. In the future, the maximal power of the injection current will also soon be raised from currently 1.5 W to 5 W. The Radiation Protection Department at SLAC worked with SSRL on the specifications for the safety systems for operation with Top-Off injection and higher beam currents.

A history of thyratron lifetimes at the Stanford Linear Accelerator Center

International Nuclear Information System (INIS)

Ficklin, D.B. Jr.

1994-12-01

The Stanford Linear Accelerator Center (SLAC) has been in almost continuous operation since the middle 1960s, providing a remarkable opportunity to amass thyratron data. This paper reviews the history of this thyratron usage, focusing primarily on data collected during the last ten years of accelerator operation. There have been two distinct operating conditions during the history of operation at SLAC. Prior to 1985, the fundamental thyratron operating points were 46 kV anode voltage (Epy), 4.2 kA peak current, 3.8 μs equivalent square pulse (esp), with a maximum repetition rate of 360 pulses per second (pps). The accelerator was upgraded during 1985, and the thyratron operating points are now 46 kV Epy, 6.3 kA, 5.4 μs esp, with a maximum repetition rate of 120 pps. The SLAC high-energy physics research program requires that each of the available modulator klystron units provide a stable microwave energy source. Within these constraints, this paper explores historical thyratron lifetimes at SLAC, reviewing the available data to determine how long these thyratrons can be expected to operate before failure currently or recently used in the 243 accelerator modulators

Revisiting the Stanford prison experiment: could participant self-selection have led to the cruelty?

Carnahan, Thomas; McFarland, Sam

The authors investigated whether students who selectively volunteer for a study of prison life possess dispositions associated with behaving abusively. Students were recruited for a psychological study of prison life using a virtually identical newspaper ad as used in the Stanford Prison Experiment (SPE; Haney, Banks & Zimbardo, 1973) or for a psychological study, an identical ad minus the words of prison life. Volunteers for the prison study scored significantly higher on measures of the abuse-related dispositions of aggressiveness, authoritarianism, Machiavellianism, narcissism, and social dominance and lower on empathy and altruism, two qualities inversely related to aggressive abuse. Although implications for the SPE remain a matter of conjecture, an interpretation in terms of person-situation interactionism rather than a strict situationist account is indicated by these findings. Implications for interpreting the abusiveness of American military guards at Abu Ghraib Prison also are discussed.

This paper describes the development of Seismic Guidelines for the Stanford Linear Accelerator Center (SLAC). Although structures have always been built conservatively, SLAC management decided to review and update their seismic guidelines. SLAC is about mid-way between the epicenters of the 8.3 Richter magnitude 1906 San Francisco and the 7.2 Loma Prieta Earthquakes. The west end of the two mile long electron/positron particle accelerator lies a half mile from the large San Andreas Fault. Suggestions for seismic planning processes were solicited from local computer manufacturing firms, universities, and federal laboratories. A Committee of the various stakeholders in SLAC's seismic planning retained an internationally known Seismic Planning Consultant and reviewed relevant standards and drafted Guidelines. A panel of seismic experts was convened to help define the hazard, site response spectra, probabilistic analysis of shaking, and near field effects. The Facility's structures were assigned to seismic classes of importance, and an initial assessment of a sample of a dozen buildings conducted. This assessment resulted in emergency repairs to one structure, and provided a open-quotes reality basisclose quotes for establishing the final Guidelines and Administrative Procedures, and a program to evaluate remaining buildings, shielding walls, tunnels, and other special structures

Milne, Jennifer L.; Sassoon, Richard E.; Hung, Emilie; Bosshard, Paolo; Benson, Sally M.

The Global Climate and Energy Project (GCEP), at Stanford University, invests in research with the potential to lead to energy technologies with lower greenhouse gas emissions than current energy technologies. GCEP is sponsored by four international companies, ExxonMobil, GE, Schlumberger, and Toyota and supports research programs in academic institutions worldwide. Research falls into the broad areas of carbon based energy systems, renewables, electrochemistry, and the electric grid. Within these areas research efforts are underway that are aimed at achieving break-throughs and innovations that greatly improve efficiency, performance, functionality and cost of many potential energy technologies of the future including solar, batteries, fuel cells, biofuels, hydrogen storage and carbon capture and storage. This paper presents a summary of some of GCEP's activities over the past 7 years with current research areas of interest and potential research directions in the near future.

A first part criticizes the work and publications of Mark Jacobson, a teacher in Stanford University, who states that wind energy and solar energy could supply the World with enough energy, and more particularly enough electricity as he supposes a generalisation of the use of electricity. His assessments for France are indicated. The author of the article outlines that some of these predictions or hypotheses are wrong. Notably, they are much higher than an assessment made by the French regions regarding their potential production. He also outlines that production could be too low in some circumstances, and thus considers that this plan is a non sense. The second part proposes a PowerPoint presentation on the properties of an electricity system with intermittent sources which describes, analyses and comments data related to the production of wind and solar energy in Germany and its evolution in time (installed power, daily variations, and so on)

1977-01-01

Recent interest in charged heavy particle irradiation is based upon expected improved local tumor control rates because of the greater precision in dose localization and the increased biological effectiveness of the high linear energy transfer ionization of particle beams in their stopping regions (Bragg peaks). A novel 60 beam cylindrical geometry pion spectrometer designed for a hospital-based pion therapy facility has been constructed at Stanford. In conjunction with the development and testing of the SMPG a program of simulated treatment planning is being conducted. This paper presents basic considerations in treatment planning for pions and other charged heavy particles. It also presents the status of simulated treatment planning calculations for the SMPG including a discussion of the principle of irradiation of hypothetical tumor volumes illustrated by examples of simplified treatment plans incorporating tissue density inhomogeneity corrections. Also presented are considerations for realistic simulated treatment planning calculations using computerized tomographic scan cross sections of actual patients and a conceptual plan for an integrated treatment planning and patient treatment system for the SMPG

2011-01-01

The first speaker in the 2011 EFRC Summit session titled 'Leading Perspectives in Energy Research' was John Hennessey, President of Stanford University. He discussed the important role that the academic world plays as a partner in innovative energy research by presenting a case study involving Stanford and SLAC. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss 'Science for our Nation's Energy Future.' In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several 'grand challenges' and use-inspired 'basic research needs' recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

Full Text Available A 48-year-old patient with hypertensive end-stage renal disease presented for cadaveric renal transplantation. On physical exam, a previously undocumented diastolic murmur was heard loudest at the left lower sternal border. The patient had a history of pericardial effusions and reported “a feeling of chest fullness” when lying flat. As such, a transesophageal echocardiogram (TEE was performed after induction of anesthesia to evaluate the pericardial space and possibly determine the etiology and severity of the new murmur. The TEE revealed a Stanford Type A aortic dissection. The renal transplant was cancelled (organ reassigned within region, and the patient underwent an urgent ascending and proximal hemiarch aortic replacement. This case demonstrates the importance of a thorough physical exam and highlights the utility of TEE for noncardiac surgical cases.

SURFS: Riding the waves with Synthetic UniveRses For Surveys

We present the Synthetic UniveRses For Surveys (SURFS) simulations, a set of N-body/Hydro simulations of the concordance Λ Cold Dark Matter (ΛCDM) cosmology. These simulations use Planck cosmology, contain up to 10 billion particles, and sample scales and halo masses down to 1 kpc and 108 M⊙. We identify and track haloes from z = 24 to today using a state-of-the-art 6D halo finder and merger tree builder. We demonstrate that certain properties of haloes merger trees are numerically converged for haloes composed of ≳100 particles. Haloes smoothly grow in mass, Vmax, with the mass history characterized by log M(a) ∝ exp [-(a/β)α], where a is the scale factor, α(M) ≈ 0.8 & β(M) ≈ 0.024, with these parameters decreasing with decreasing halo mass. Subhaloes follow power-law cumulative mass and velocity functions, i.e. n( > f) ∝ f-α with αM = 0.83 ± 0.01 and α _{V_max}=2.13± 0.03 for mass and velocity, respectively, independent of redshift, as seen in previous studies. The halo-to-halo scatter in amplitude is 0.9 dex. The number of subhaloes in a halo weakly correlates with a halo's concentration c and spin λ:haloes of high c and low λ have 60 per cent more subhaloes than similar mass haloes of low c and high λ. High cadence tracking shows subhaloes are dynamic residents, with 25 per cent leaving their host halo momentarily, becoming a backsplash subhalo, and another 20 per cent changing hosts entirely, in agreement with previous studies. In general, subhaloes have elliptical orbits, e ≈ 0.6, with periods of 2.3^{+2.1}_{-1.7} Gyrs. Subhaloes lose most of their mass at pericentric passage with mass loss rates of ˜ 40 per cent Gyr-1. These catalogues will be made publicly available.

Full Text Available Vaste mise en miroir d’une fiction qui n’en finit pas d’interroger son rapport ambigu au réel, le chef d’œuvre de Cervantès place le mouvement dialectique entre univers fictionnel et réalité au cœur même de son écriture. Au sein de cette dialectique, l’amour multiplement fictionnel de don Quichotte pour Dulcinée joue cependant un rôle majeur que ce travail se propose d’examiner. Lieu d’épanouissement privilégié d’un questionnement du rapport entre fiction et réalité, la mise en écriture de cet amour participe en effet de la vaste entreprise de révision des concepts menée par la pensée humaniste : c’est une exploration de la notion même d’amour, de sa réalité, de sa vérité, que permet le voyage au pays de l’amour auquel le Quichotte de Cervantès invite le lecteur.

Korea Nuclear Energy Promotion Agency(hereafter, referred as KONEPA) is a public institution established in March, 1992 to improve correct understanding of nuclear energy through development and dissemination of objective, scientific knowledge on the peaceful use of nuclear energy. KONEPA divided the targeted group into four large groups? opinion leaders, civil-social group, LOCA governments, general public/next-generation students/teachers? according to the knowledge levels of nuclear power and involvements in nuclear power plants, and implemented 'customized strategy' suited to the own characteristic of each group. Of these four groups, the next generation, focused on the 'Univ. students' will be discussed with their activities and future plans in this paper

The Stanford Biodesign Program began in 2001 with a mission of helping to train leaders in biomedical technology innovation. A key feature of the program is a full-time postgraduate fellowship where multidisciplinary teams undergo a process of sourcing clinical needs, inventing solutions and planning for implementation of a business strategy. The program places a priority on needs identification, a formal process of selecting, researching and characterizing needs before beginning the process of inventing. Fellows and students from the program have gone on to careers that emphasize technology innovation across industry and academia. Biodesign trainees have started 26 companies within the program that have raised over $200 million and led to the creation of over 500 new jobs. More importantly, although most of these technologies are still at a very early stage, several projects have received regulatory approval and so far more than 150,000 patients have been treated by technologies invented by our trainees. This paper reviews the initial outcomes of the program and discusses lessons learned and future directions in terms of training priorities.

Optical tuning in the arcs and final focus sections of the Stanford Linear Collider

In this thesis, we present the experimental tuning procedures developed for the Arcs and for the Final Focus Section of the Stanford Linear Collider (SLC). Such tuning is necessary to maximize the luminosity, by minimizing the beam size at the interaction point, and to reduce backgrounds in the experiment. In the final Focus Section, the correction strategy must result from the principles of the optical design, which is based on cancellations between second order aberrations, and on the ability to measure micron-size beams typical of the SLC. In the Arcs, the corrections were designed after the initial commissioning, to make the system more error-tolerant, through a modification in the optical design, and to enable adjustments of the beam phase-space a the injection to the Final Focus System, through a harmonic perturbation technique inspired from circular accelerators. Although the overall optimization of the SLC is not entirely finished, an almost optimal set-up has been achieved for the optics of the Arcs and of the Final Focus Section. Beams with transverse sizes close to the nominal ones, of a few microns, have been obtained at the interaction point. We present and discuss our results and the optical limits to the present performance. 24 refs., 25 figs., 2 tabs

Natural ventilation can significantly reduce building energy consumption, but robust design is a challenging task. We previously presented predictions of natural ventilation performance in Stanford's Y2E2 building using two models with different levels of fidelity, embedded in an uncertainty quantification framework to identify the dominant uncertain parameters and predict quantified confidence intervals. The results showed a slightly high cooling rate for the volume-averaged temperature, and the initial thermal mass temperature and window discharge coefficients were found to have an important influence on the results. To further investigate the potential role of these parameters on the observed discrepancies, the current study is performing additional measurements in the Y2E2 building. Wall temperatures are recorded throughout the nightflush using thermocouples; flow rates through windows are measured using hotwires; and spatial variability in the air temperature is explored. The measured wall temperatures are found the be within the range of our model assumptions, and the measured velocities agree reasonably well with our CFD predications. Considerable local variations in the indoor air temperature have been recorded, largely explaining the discrepancies in our earlier validation study. Future work will therefore focus on a local validation of the CFD results with the measurements. Center for Integrated Facility Engineering (CIFE).

Stanford Biodesign launched its Innovation Fellowship in 2001 as a first-of-its kind postgraduate training experience for teaching biomedical technology innovators a need-driven process for developing medical technologies and delivering them to patients. Since then, many design-oriented educational programs have been initiated, yet the impact of this type of training remains poorly understood. This study measures the career focus, leadership trajectory, and productivity of 114 Biodesign Innovation Fellowship alumni based on survey data and public career information. It also compares alumni on certain publicly available metrics to finalists interviewed but not selected. Overall, 60% of alumni are employed in health technology in contrast to 35% of finalists interviewed but not selected. On leadership, 72% of alumni hold managerial or higher positions compared to 48% of the finalist group. A total of 67% of alumni reported that the fellowship had been "extremely beneficial" on their careers. As a measure of technology translation, more than 440,000 patients have been reached with technologies developed directly out of the Biodesign Innovation Fellowship, with another 1,000,000+ aided by solutions initiated by alumni after their training. This study suggests a positive impact of the fellowship program on the career focus, leadership, and productivity of its alumni.

Stanford SsTO Mission to Mars: A Realistic, Safe and Cost Effective Approach to Human Mars Exploration Using the Stanford SsTO Launch System

Osborne, Robert D.

1999-06-01

In recent years, a lot of time and energy has been spent exploring possible mission scenarios for a human mission to Mars. NASA along with the privately funded Mars Society and a number of universities have come up with many options that could place people on the surface of Mars in a relatively short period of time at a relatively low cost. However, a common theme among all or at least most of these missions is that they require heavy lift vehicles such as the Russian Energia or the NASA proposed Magnum 100MT class vehicle to transport large payloads from the surface of Earth into a staging orbit about Earth. However, there is no current budget or any signs for a future budget to review the Russian Energia, the US made Saturn V, or to design and build a new heavy lift vehicle. However, there is a lot of interest and many companies looking into the possibility of "space planes". These vehicles will have the capability to place a payload into orbit without throwing any parts of the vehicle away. The concept of a space plane is basically that the plane is transported to a given altitude either by it's own power or on the back of another air worthy vehicle before the rocket engines are ignited. From this altitude, a Single Step to Orbit (SsTO) vehicle with a significant payload is possible. This report looks at the possibility of removing the requirement of a heavy lift vehicle by using the Stanford designed Single Step to Orbit.(SsTO) Launch Vehicle. The SsTO would eliminate the need for heavy lift vehicles and actually reduce the cost of the mission because of the very low costs involved with each SSTO launch. Although this scenario may add a small amount of risk assembling transfer vehicles in Earth orbit, it should add no additional risk to the crew.

Opportunistic or event-driven maintenance at the Stanford Linear Accelerator Center

The Stanford Linear Accelerator Center (SLAC) uses a maintenance management philosophy that is best described as opportunistic or event-driven. Opportunistic maintenance can be defined as a systematic method of collecting, investigating, pre-planning, and publishing a set of proposed maintenance tasks and acting on them when there is an unscheduled failure or repair ''opportunity''. Opportunistic maintenance can be thought of as a modification of the run-to-fail maintenance management philosophy. This maintenance plan was adopted and developed to improve the overall availability of SLAC's linear accelerator, beam delivery systems, and associated controls, power systems, and utilities. In the late 1980's, as the technical complexity of the accelerator facility increased, variations on a conventional maintenance plan were used with mixed results. These variations typically included some type of regular periodic interruption to operations. The periodic shutdowns and unscheduled failures were additive and resulted in unsatisfactory availability. Maintenance issues are evaluated in a daily meeting that includes the accelerator managers, maintenance supervisors and managers, safety office personnel, program managers, and accelerator operators. Lists of pending maintenance tasks are made available to the general SLAC population by a World Wide Web site on a local internet. A conventional information system which pre-dates the WWW site is still being used to provide paper copies to groups that are not yet integrated into the WWW system. The local internet provides real time maintenance information, allowing people throughout the facility to track progress on tasks with essentially real-time status updates. With the introduction of opportunistic maintenance, the accelerator's availability has been measurably better. This paper will discuss processes, rolls and responsibilities of key maintenance groups, and management tools developed to support opportunistic maintenance

We report a case of a 36-year-old woman at 34 weeks of gestation complicated with Marfan syndrome who underwent Bentall type aortic replacement surgery due to Stanford type A aortic dissection after undergoing caesarean section. Since this patient exhibited severe hypotension before coming to the operating room, it was very difficult to determine whether the cardiac surgery or caesarean section should be performed first. In this case, the caesarean section was performed first, followed by Bentall's surgery. Although intra-aortic balloon pumping and percutaneous cardiopulmonary support were required after weaning from the cardiopulmonary bypass, she was discharged on post-operative day (POD) 40 and the baby was discharged on POD 60, without signs of cerebral palsy. Unfortunately, this patient died on POD 57, due to heart failure. We discuss how to determine the priority of surgeries for patients who require emergency surgery for cardiovascular disease during pregnancy.

Measurement and Instrumentation Challenges at X-ray Free Electron Lasers

X-ray Free Electron Laser sources based on the Self Amplified Spontaneous Emission process are intrinsically chaotic, giving rise to pulse-to-pulse fluctuations in all physical properties, including intensity, position and pointing, spatial and temporal profiles, spectral content, timing, and coherence. These fluctuations represents special challenges to users whose experiments are designed to reveal small changes in the underlying physical quantities, which would otherwise be completely washed out without using the proper diagnostics tools. Due to the X-ray FEL's unique characteristics such as the unprecedented peak power and nearly full spatial coherence, there are many technical challenges in conceiving and implementing these devices that are highly transmissive, provide sufficient signal-to-noise ratio, and most importantly work in the single-shot mode. Portions of this research were carried out at the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory. LCLS is an Office of Science User Facility operated for the U.S. Department of Energy Office of Science by Stanford Univ.

The fifth edition of the Stanford-Binet Intelligence scales allows 'full scale' IQ (FSIQ) to be estimated using an abridged version of the test-the abbreviated battery IQ (ABIQ). Set within a public early intervention team service, the current cross-sectional study investigated the utility of the ABIQ in estimating FSIQ for 40 children with autism spectrum disorder (ASD) aged 3-5 years. A strong ABIQ-FSIQ association was yielded (r = 0.89; r 2  = 0.808) and the ABIQ did not over-estimate mean FSIQ above a clinically-relevant threshold; however, clinically significant over-estimation occurred in 17.5% of individual cases. While the findings provide support for the utility of the ABIQ in estimating FSIQ for young children with ASD, caution relating to the over-estimation of FSIQ is warranted. Careful clinical judgment-ideally based on examination of previous cognitive assessment results (if available), thorough interactional observations, and close multi-disciplinary consultation-is necessary to determine the applicability of the ABIQ to individual cases.

Continuing the Original Stanford Sleep Surgery Protocol From Upper Airway Reconstruction to Upper Airway Stimulation: Our First Successful Case.

Science.gov (United States)

Liu, Stanley Yung; Riley, Robert Wayne

2017-07-01

In 1993, a surgical protocol for dynamic upper airway reconstruction in patients with obstructive sleep apnea (OSA) was published, and it became commonly known as the Stanford phase 1 and 2 sleep surgery protocol. It served as a platform on which research and clinical studies have continued to perfect the surgical care of patients with OSA. However, relapse is inevitable in a chronic condition such as OSA, and a subset of previously cured surgical patients return with complaints of excessive daytime sleepiness. This report describes a patient who was successfully treated with phase 1 and 2 operations more than a decade previously. He returned at 65 years of age with relapse of moderate OSA, and after workup with polysomnography and drug-induced sleep endoscopy, he underwent upper airway stimulation of the hypoglossal nerve that resulted in a cure of OSA. This case shows why upper airway stimulation is an appropriate option for patients with OSA relapse, after previously successful maxillomandibular advancement. Copyright © 2017.

The Freie Univ Evaluation System Framework (Freva - freva.met.fu-berlin.de) is a software infrastructure for standardized data and tool solutions in Earth system science (e.g. www-miklip.dkrz.de, cmip-eval.dkrz.de). Freva runs on high performance computers to handle customizable evaluation systems of research projects, institutes or universities. It combines different software technologies into one common hybrid infrastructure, including all features present in the shell and web environment. The database interface satisfies the international standards provided by the Earth System Grid Federation (ESGF). Freva indexes different data projects into one common search environment by storing the meta data information of the self-describing model, reanalysis and observational data sets in a database. This implemented meta data system with its advanced but easy-to-handle search tool supports users, developers and their plugins to retrieve the required information. A generic application programming interface (API) allows scientific developers to connect their analysis tools with the evaluation system independently of the programming language used. Users of the evaluation techniques benefit from the common interface of the evaluation system without any need to understand the different scripting languages. The integrated web-shell (shellinabox) adds a degree of freedom in the choice of the working environment and can be used as a gate to the research projects HPC. Plugins are able to integrate their e.g. post-processed results into the database of the user. This allows e.g. post-processing plugins to feed statistical analysis plugins, which fosters an active exchange between plugin developers of a research project. Additionally, the history and configuration sub-system stores every analysis performed with the evaluation system in a database. Configurations and results of the tools can be shared among scientists via shell or web system. Furthermore, if configurations match

The 100 meter diameter Green Bank Telescope, with its large frequency coverage, great sensitivity, all-sky tracking, and location at a protected, radio-quiet site, offers a unique platform for technological advances in astronomical instrumentation that can yield an immediate scientific payoff.MUSTANG-1.5 is a feedhorn-coupled bolometer array for 3mm that has recently been installed on the telescope. It has 64 pixels (expandable to 223) and offers sensitivity to angular scales from 9" to more than 3' over a band from 75 GHz to 105 GHz. Its capabilities for science at 3mm are complimentary to, and in some cases superior to, those offered by ALMA. MUSTANG-1.5 is a collaboration between UPenn., NIST, NRAO, and other institutions.ARGUS is a 16-pixel focal plane array for millimeter spectroscopy that will be in use on the GBT in 2015. The array architecture is designed as a scalable technology pathfinder for larger arrays, but by itself it will provide major capabilities for spectroscopy from 75-107 GHz with 8" angular resolution over a wide field-of-view. It is a collaboration between Stanford Univ., Caltech, JPL, Univ. Maryland, Univ. Miami, and NRAO.FLAG is a prototype phased array receiver operating at 21cm wavelength that is under development for the GBT. It will produce multiple beams over a wide field of view with a sensitivity competitive with that of single-pixel receivers, allowing rapid astronomical surveys. FLAG is a collaboration between BYU, WVU, and NRAO.Also under development is a mm-wave phased array receiver for the GBT, designed to operate near 90 GHz as a prototype for very large format phased array receivers in the 3mm band. It is a collaboration between UMass and BYU.VEGAS is the new spectrometer for the GBT, offering multiple configurations well matched to GBT receivers from 1 to 100 GHz and suitable for use with focal plane arrays. It is a collaboration between UCal (Berkeley) and NRAO.The new receivers and spectrometers create extremely big data

This study assessed the concurrent validity of the English and a linguistic Spanish translation of the Stanford Brief Activity Survey (SBAS) with pedometer-measured physical activity (PA) among postpartum Latinas. Latinas (n 97) completed the SBAS in either English (n 47) or Spanish (n 50) and wore pedometers 7 days at three different assessment periods. The English version demonstrated significant trends (p .01) for differentiating aerobic walking steps (AWS) and aerobic walking time (AWT) across SBAS intensity categories at two of the three assessment periods. The Spanish version showed marginally significant trends for differentiating AWS (p .048) and AWT (p .052) across SBAS intensity categories at only one assessment period. The English version of the SBAS is effective in assessing PA status among Latinas; however, the Spanish version indicates a need for research to further explore cultural and linguistic adaptations of the SBAS.

Systems-level approaches are increasingly common in both murine and human translational studies. These approaches employ multiple high information content assays. As a result, there is a need for tools to integrate heterogeneous types of laboratory and clinical/demographic data, and to allow the exploration of that data by aggregating and/or segregating results based on particular variables (e.g., mean cytokine levels by age and gender). Here we describe the application of standard data warehousing tools to create a novel environment for user-driven upload, integration, and exploration of heterogeneous data. The system presented here currently supports flow cytometry and immunoassays performed in the Stanford Human Immune Monitoring Center, but could be applied more generally. Users upload assay results contained in platform-specific spreadsheets of a defined format, and clinical and demographic data in spreadsheets of flexible format. Users then map sample IDs to connect the assay results with the metadata. An OLAP (on-line analytical processing) data exploration interface allows filtering and display of various dimensions (e.g., Luminex analytes in rows, treatment group in columns, filtered on a particular study). Statistics such as mean, median, and N can be displayed. The views can be expanded or contracted to aggregate or segregate data at various levels. Individual-level data is accessible with a single click. The result is a user-driven system that permits data integration and exploration in a variety of settings. We show how the system can be used to find gender-specific differences in serum cytokine levels, and compare them across experiments and assay types. We have used the tools and techniques of data warehousing, including open-source business intelligence software, to support investigator-driven data integration and mining of diverse immunological data.

Essentially all we know today and will learn in the future about the fundamental nature of matter is derived from probing it with directed beams of particles such as electrons, protons, neutrons, heavy ions, and photons. The resulting ability to “see” the building blocks of matter has had an immense impact on society and our standard of living. Over the last century, particle accelerators have changed the way we look at nature and the universe we live in and have become an integral part of the Nation’s technical infrastructure. Today, particle accelerators are essential tools of modern science and technology. The cost and capabilities of accelerators would be greatly enhanced by breakthroughs in acceleration methods and technology. For the last 32 years, the Advanced Accelerator Concepts (AAC) Workshop has acted as the focal point for discussion and development of the most promising acceleration physics and technology. It is a particularly effective forum where the discussion is leveraged and promoted by the unique and demanding feature of the AAC Workshop: the working group structure, in which participants are asked to consider their contributions in terms of even larger problems to be solved. The 16th Advanced Accelerator Concepts (AAC2014) Workshop was organized by Stanford University from July 13 - 18, 2014 at the Dolce Hays Mansion in San Jose, California. The conference had a record 282 attendees including 62 students. Attendees came from 11 countries representing 66 different institutions. The workshop format consisted of plenary sessions in the morning with topical leaders from around the world presenting the latest breakthroughs to the entire workshop. In the late morning and afternoons attendees broke out into eight different working groups for more detailed presentations and discussions that were summarized on the final day of the workshop. In addition, there were student tutorial presentations on two afternoons to provide in depth education and

Nineteen patients with Stanford type A acute aortic dissection with closed false lumen were reviewed. In the follow-up examinations, ulcerlike projection (ULP) in the ascending aorta (AA) or aortic arch (AR) was identified in 8 of 19 patients. In 5 of these 8 patients, acute cardiac tamponade occurred and 3 of them died. In the other 11 patients, there was no mortality, and only one patient underwent elective surgery. The appearance of ULP in the AA/AR is considered an indication for urgent surgery because it is regarded as a precursor of lethal complications such as cardiac tamponade. The purpose of this study was to investigate predictors of the appearance of ULP in the AA/AR with early imagings (CT or MRI) before the appearance of ULP. The patients were divided into two groups: patients with ULP in the AA/AR (8 patients) and others (11 patients). Initial CT or MRI findings of the thoracic aorta were retrospectively statistically analyzed in each group. Three predictive factors were statistically significant for the appearance of ULP in the AA/AR (diameter of the AA{>=}5 cm, thickness of the false lumen of the AA{>=}1 cm, thickness of the false lumen of the AA{>=} that of the descending aorta). Close attention should be paid, if any of these 3 factors is observed at initial CT or MRI. (author)

A symposium on the transportation of hazardous goods sponsored by the University of Toronto, the Canadian Society for Chemical Engineering, and Oyez Ltd. (Toronto May 1980), in view of a 11/10/79 explosion at Mississauga, Ont., following derailment of a Canadian Pacific Railways train carrying chlorine gas, covers comments by D. MacKay (Univ. Toronto), on the importance of quantifying the probability of an accident in transporting such hazardous materials as LPG's, chlorine, and corrosive acids, and of formulating contingency plans to reduce the probability or mitigate the effects; by W. Canniff of the Canadian Chemical Producers Association, on that group's Transportation Emergency Assistance Plan, which relies on the shipper of the chemical involved in an accident to provide advice and assistance; by R.J. Coleman (San Clemente, Calif., Fire Dep.), on coordination of efforts between firefighting and other emergency-handling groups to avoid confusion; by T.D. Ellison (Transp. Can.), on proposed Canadian legislation on the transport of dangerous goods, which would adopt, among others, a product classification system now used for international sea transport and a new system of labeling packages; and by D. Estrin, on the limitations of this proposed legislation.

Purpose: To analyze how prostate-specific antigen (PSA) screening and practice patterns has affected trends in tumor characteristics in men undergoing radical prostatectomy (RP) in the United States and Denmark. Unlike in the United States, PSA screening has not been recommended in Denmark...... evaluated with Cochran-Armitage test for trends and chi-square testing. Results: A total of 4404 patients were included. Temporal changes in preoperative PSA, age, grade, and stage was found in both cohorts. Median preoperative PSA declined in both cohorts, while median age increased, with the Danish cohort...... showing the greatest changes in both PSA and age. In both cohorts, there was a trend for higher-risk preoperative features before RP over time. In 2010-2013, 27.7% and 21.8% of the patients were in the D'Amico high-risk group at Copenhagen and Stanford, respectively. Conclusion: Despite recommendation...

Gonadal status and reproductive function following treatment for Hodgkin's disease in childhood: The Stanford experience

Ortin, T.T.; Shostak, C.A.; Donaldson, S.S.

1990-01-01

To ascertain the impact of therapy on gonadal function and reproductive outcome among children treated for Hodgkin's disease, we reviewed the experience at Stanford University Medical Center during the years 1965-1986. There were 240 children 15 years of age or younger, 92 girls and 148 boys; with median follow-up of 9 years, maximum follow-up was 26 years. Of this cohort, data on gonadal function were available on 20 boys, 5 of whom were considered prepubescent; they had no clinical evidence of sexual maturation and were less than 13 years of age. Evaluation of the boys included testicular biopsy, semen analyses and the ability to procreate. Serum gonadotropin hormone levels (FSH, LH) were studied in 11 boys who also had semen analyses. Sexual maturation was attained in all boys without the need for androgen replacement. Among the eight boys treated with radiation alone, four were able to father a child (3 following 40-45 Gy pelvic radiation dose, 1 without pelvic radiation) from 3-19 years following treatment. Three others who received 30-44 Gy pelvic radiation were oligospermic when tested at 10 to 15 years post-treatment. Semen analyses in 10 of 12 (83%) boys who had been treated with six cycles of MOPP with or without pelvic radiation revealed absolute azoospermia with no evidence of recovery as along as 11 years of follow-up. Following prolonged azoospermia, 2 of the 12 boys (17%) had recovery of fertility, with normalization of sperm count and/or ability to procreate at 12 and 15 years following treatment. There was no correlation with serum gonadotropin levels and sterility. Data on menstrual history, pregnancy and offspring were available in 86 (92%) of the girls. Seventy-five of the 86 girls (87%) have normal menstrual function. However, none of the females who underwent pelvic radiation without prior oophoropexy has maintained ovarian function

Proposed heat transfer model for the gas-liquid heat transfer effects observed in the Stanford Research Institute scaled tests

International Nuclear Information System (INIS)

Corradini, M.; Sonin, A.A.; Todreas, N.

1976-12-01

In 1971-72, the Stanford Research Institute conducted a series of scaled experiments which simulated a sodium-vapor expansion in a hypothetical core disruptive accident (HCDA) for the Fast Flux Test Facility. A non-condensible explosive source was used to model the pressure-volume expansion characteristics of sodium vapor as predicted by computer code calculations. Rigid piston-cylinder experiments ( 1 / 10 and 1 / 30 scale) were undertaken to determine these expansion characteristics. The results showed that the pressure-volume characteristics depend significantly on the presence of water in the cylinder reducing the work output by about 50 percent when a sufficient water depth was present. The study presented proposes that the mechanism of heat transfer between the water and high temperature gas was due to area enhancement by Taylor instabilities at the gas-liquid interface. A simple heat transfer model is proposed which describes this energy transport process and agrees well with the experimental data from both scaled experiments. The consequences of this analysis suggest that an estimate of the heat transfer to the cold slug during a full-scale HCDA due to sodium vapor expansion and the accompanying reduction in mechanical work energy warrants further investigation. The implication of this analysis is that for either sodium or fuel vapor expansion in an HCDA, there is an inherent heat transfer mechanism which significantly reduces the work output of the expanding bubble

Full Text Available Empowerment evaluation was adopted by Stanford University's School of Medicine to engage in curricular reform. It was also used to prepare for an accreditation site visit. Empowerment evaluation is a guided form of self-evaluation. It was selected because the principles and practices of empowerment evaluation resonated with the collaborative and participatory nature of the curricular reform in the School. This article highlights one of the most important features of an empowerment evaluation: a critical friend. This individual has evaluation expertise but serves as a coach, advisor, or guide, rather than "the expert". The evaluation is in the hands of the people in the program, but a critical friend helps to keep it on track and rigorous. As one indication of the importance of this role, student ratings on selected clerkship rotations, where a critical friend was requested to respond to student concerns, resulted in significant increases in student ratings.La evaluación de concesión legal de poder fue adoptada por la Escuela de Medicina de la Universidad de Stanford para participar de la reforma curricular.

Los principios y prácticas de evaluación legal de poder corresponden harmoniosamente a la naturaleza colaboradora y participativa de la reforma curricular en la escuela. Este artigo destaca una de las más importantes características de la evaluación de concesión legal de poder: el amigo crítico. Este individuo tiene experiencia en evaluación, pero sirve como instructor, consejero y guía en lugar del "perito".

Constraints on spatially oscillating sub-mm forces from the Stanford Optically Levitated Microsphere Experiment data

Science.gov (United States)

Antoniou, I.; Perivolaropoulos, L.

2017-11-01

A recent analysis by one of the authors [L. Perivolaropoulos, Phys. Rev. D 95, 084050 (2017), 10.1103/PhysRevD.95.084050] has indicated the presence of a 2 σ signal of spatially oscillating new force residuals in the torsion balance data of the Washington experiment. We extend that study and analyze the data of the Stanford Optically Levitated Microsphere Experiment (SOLME) [A. D. Rider et al., Phys. Rev. Lett. 117, 101101 (2016), 10.1103/PhysRevLett.117.101101] (kindly provided by A. D. Rider et al.) searching for sub-mm spatially oscillating new force signals. We find a statistically significant oscillating signal for a force residual of the form F (z )=α cos (2/π λ z +c ) where z is the distance between the macroscopic interacting masses (levitated microsphere and cantilever). The best fit parameter values are α =(1.1 ±0.4 )×10-17N , λ =(35.2 ±0.6 ) μ m . Monte Carlo simulation of the SOLME data under the assumption of zero force residuals has indicated that the statistical significance of this signal is at about 2 σ level. The improvement of the χ2 fit compared to the null hypothesis (zero residual force) corresponds to Δ χ2=13.1 . There are indications that this previously unnoticed signal is indeed in the data but is most probably induced by a systematic effect caused by diffraction of non-Gaussian tails of the laser beam. Thus the amplitude of this detected signal can only be useful as an upper bound to the amplitude of new spatially oscillating forces on sub-mm scales. In the context of gravitational origin of the signal emerging from a fundamental modification of the Newtonian potential of the form Veff(r )=-G M/r (1 +αOcos (2/π λ r +θ ))≡VN(r )+Vosc(r ) , we evaluate the source integral of the oscillating macroscopically induced force. If the origin of the SOLME oscillating signal is systematic, the parameter αO is bounded as αOchameleon oscillating potentials etc.).

To understand factors which enhance or detract from farmers' market shopper experiences to inform targeted interventions to increase farmers' market utilization, community-building and social marketing strategies. A consumer-intercept study using the Stanford Healthy Neighborhood Discovery Tool to capture real-time perceptions via photographs and audio narratives. An urban farmers' market in a large metropolitan US city. Thirty-eight farmers' market shoppers, who recorded 748 unique coded elements through community-based participatory research methods. Shoppers were primarily women (65 %), 18-35 years of age (54 %), non-Hispanic (81 %) and white (73 %). Shoppers captured 291 photographs (7·9 (sd 6·3) per shopper), 171 audio narratives (5·3 (sd 4·7) per shopper), and ninety-one linked photograph + audio narrative pairs (3·8 (sd 2·8) per shopper). A systematic content analysis of the photographs and audio narratives was conducted by eight independent coders. In total, nine common elements emerged from the data that enhanced the farmers' market experience (61·8 %), detracted from the experience (5·7 %) or were neutral (32·4 %). The most frequently noted elements were freshness/abundance of produce (23·3 %), product presentation (12·8 %), social interactions (12·4 %) and farmers' market attractions (e.g. live entertainment, dining offerings; 10·3 %). While produce quality (i.e. freshness/abundance) was of primary importance, other contextual factors also appeared important to the shoppers' experiences. These results may inform social marketing strategies to increase farmers' market utilization and community-building efforts that target market venues.

SPEAR3 Workshop: Making the Scientific Case: Report from Workshop held at Stanford Synchrotron Radiation Laboratory, May 29-30, 1997

Energy Technology Data Exchange (ETDEWEB)

Brennan, S.

1998-08-13

As part of the planning process for the proposed upgrade to the SPEAR electron storage ring, SSRL, the SSRL Users Organization and the SSRL faculty sponsored a 1 1/2 day workshop on May 29-30 1997. The goal was to assess and document the impact of SPEAR3 on current and future science and technology research programs of the users of SSRL. The hard and soft x-ray beams produced at SSRL are used in a number of different scientific and technological disciplines. The workshop was organized by defining a set of areas of science and technology covering the basic activities at SSRL and inviting key people from outside Stanford to work with the SSRL faculty and staff in a set of topical groups on estimating the impact of SPEAR3 on their respective fields and developing a vision of the future opportunities. This report documents those scientific and technological opportunities and provides written summaries of the discussions. The report is organized with a brief technical description of SPEAR3 and planned beam line upgrades (which summarizes material presented to the workshop participants prior to the breakout sessions) following this executive summary. More detailed information from the topical working groups then follows. Finally, an appendix provides a list of workshop participants and a copy of the workshop agenda as well as some more detailed information on the SPEAR3 lattice and machine.

Report on the Stanford/KACST/AMES UVLED small satellite mission to demonstrate charge management of an electrically isolated proof mass for drag-free operation

Science.gov (United States)

Saraf, Shailendhar

A spacecraft demonstration of ultra-violet (UV) LEDs and UV LED charge management based on research done at Stanford University is being developed jointly by the King Abdulaziz City for Science and Technology (KACST) Saudi Arabia and NASA Ames Research Center, with an expected launch date of June 2014. This paper will report on the payload design and testing, mission preparation, satellite launch and payload bring -up in space. Mission lifetime is expected to be at least one month, during which time the ability for the UV LEDs to mitigate actual space-based charging and the effects of radiation on the UV LED device performance will be studied. Precise control over the potential of an electrically isolated proof mass is necessary for the operation of devices such as a Gravitational Reference Sensor (GRS) and satellite missions such as LISA. The mission will demonstrate that AlGaN UV LEDs operating at 255 nm are an effective low-cost, low-power and compact substitute for Mercury vapor lamps used in previous missions. The goal of the mission is to increase the UV LED device to TRL-9 and the charge management system to TRL-7.

Solar magnetic field - 1976 through 1985: an atlas of photospheric magnetic field observations and computed coronal magnetic fields from the John M. Wilcox Solar Observatory at Stanford, 1976-1985

Daily magnetogram observations of the large-scale photospheric magnetic field have been made at the John M. Wilcox Solar Observatory at Stanford since May of 1976. These measurements provide a homogeneous record of the changing solar field through most of Solar Cycle 21. Using the photospheric data, the configuration of the coronal and heliospheric fields can be calculated using a Potential Field -- Source Surface model. This provides a 3-dimensional picture of the heliospheric field-evolution during the solar cycle. In this report the authors present the complete set of synoptic charts of the measured photospheric magnetic field, the computed field at the source surface, and the coefficients of the multipole expansion of the coronal field. The general underlying structure of the solar and heliospheric fields, which determine the environment for solar - terrestrial relations and provide the context within which solar-activity-related events occur, can be approximated from these data

Full Text Available The paper offers new arguments for the more exact dating – autumn-winter of 963 – of the manuscript of the treatise De cerimoniis aulae byzantinae (Leipzig, Univ. Bibl. Rep. I 17. At the end of the list of the tombs of the emperors in the Mausoleum of Constantine the Great in the Church of the Holy Apostles, included in this compilation treatise, the scribe missed three empty lines. The last emperor in the list of buried emperors is Constantine VII Porphyrogenitus; there is no sarcophagus of his son Roman II, known from the later lists of tombs. The list ends with a mention of the “small sarcophagus” (τὸ λαρνάκιον; and there is no indication, whether there was someone buried there. Judging by the chronicles of Yahya of Antioch and Leo Deacon, as well as The Brief History by Michael Psellos, since the death of Emperor Roman II there was a constant danger of the liquidation of his children – Basil, Constantine and Anna. Apparently, this small coffin was prepared for them, and the scribe of the codex left a place to finish the final distribution of the last representatives of the imperial house in the mausoleum. However, all the children saved their lives, and three blank lines in the manuscript were never filled. Consequently, the manuscript was already completed after August 16, 963, and it is unlikely that the work on it was completed much later than the autumn-winter of 963.

1990-10-01

To ascertain the impact of therapy on gonadal function and reproductive outcome among children treated for Hodgkin's disease, we reviewed the experience at Stanford University Medical Center during the years 1965-1986. There were 240 children 15 years of age or younger, 92 girls and 148 boys; with median follow-up of 9 years, maximum follow-up was 26 years. Of this cohort, data on gonadal function were available on 20 boys, 5 of whom were considered prepubescent; they had no clinical evidence of sexual maturation and were less than 13 years of age. Evaluation of the boys included testicular biopsy, semen analyses and the ability to procreate. Serum gonadotropin hormone levels (FSH, LH) were studied in 11 boys who also had semen analyses. Sexual maturation was attained in all boys without the need for androgen replacement. Among the eight boys treated with radiation alone, four were able to father a child (3 following 40-45 Gy pelvic radiation dose, 1 without pelvic radiation) from 3-19 years following treatment. Three others who received 30-44 Gy pelvic radiation were oligospermic when tested at 10 to 15 years post-treatment. Semen analyses in 10 of 12 (83%) boys who had been treated with six cycles of MOPP with or without pelvic radiation revealed absolute azoospermia with no evidence of recovery as along as 11 years of follow-up. Following prolonged azoospermia, 2 of the 12 boys (17%) had recovery of fertility, with normalization of sperm count and/or ability to procreate at 12 and 15 years following treatment. There was no correlation with serum gonadotropin levels and sterility. Data on menstrual history, pregnancy and offspring were available in 86 (92%) of the girls. Seventy-five of the 86 girls (87%) have normal menstrual function. However, none of the females who underwent pelvic radiation without prior oophoropexy has maintained ovarian function.

Full Text Available BACKGROUND: Endovascular stent-graft repair of aortic dissections is a relatively new procedure, and although apparently less invasive, the efficacy and safety of this technique have not been fully established. OBJECTIVE: To evaluate mortality in patients with complicated Stanford type B aortic dissections submitted to endovascular treatment. METHODS: Clinical, anatomical, imaging and autopsy data of 23 patients with complicated type B aortic dissections were reviewed from November 2004 to October 2007. The main indications for transluminal thoracic stent-grafting included: persistent pain in spite of medical therapy, signs of distal limb ischemia, signs of aortic rupture, progression of aneurismal dilation of the descending aorta during follow-up (defined as a diameter > 50 mm and the diameter of descending thoracic aorta of 40mm or larger at the onset of aortic dissection. Data were analyzed statistically; all p-values were two-tailed and differences INTRODUÇÃO: O tratamento endovascular na dissecção de aorta é um procedimento relativamente novo e, embora aparentemente menos invasivo, a eficácia e a segurança dessa técnica não estão totalmente estabelecidas.

Faculty in academic medicine experience multiple demands on their time at work and home, which can become a source of stress and dissatisfaction, compromising success. A taskforce convened to diagnose the state of work-life flexibility at Stanford University School of Medicine uncovered two major sources of conflict: work-life conflict, caused by juggling demands of career and home; and work-work conflict, caused by competing priorities of the research, teaching, and clinical missions combined with service and administrative tasks. Using human-centered design research principles, the 2013-2014 Academic Biomedical Career Customization (ABCC) pilot program incorporated two elements to mitigate work-life and work-work conflict: integrated career-life planning, coaching to create a customized plan to meet both career and life goals; and a time-banking system, recognizing behaviors that promote team success with benefits that mitigate work-life and work-work conflicts. A matched-sample pre-post evaluation survey found the two-part program increased perceptions of a culture of flexibility (P = .020), wellness (P = .013), understanding of professional development opportunities (P = .036), and institutional satisfaction (P = .020) among participants. In addition, analysis of research productivity indicated that over the two-year program, ABCC participants received 1.3 more awards, on average, compared with a matched set of nonparticipants, a funding difference of approximately $1.1 million per person. These results suggest it is possible to mitigate the effects of extreme time pressure on academic medicine faculty, even within existing institutional structures.

We previously reported results of our on-line microsurgery training program, showing that residents who had access to our website significantly improved their cognitive and technical skills. In this study, we report an objective means for expert evaluators to reliably rate trainees' technical skills under the microscope, with the use of our novel global rating scale. "Microsurgery Essentials" (http://smartmicrosurgery.com) is our on-line training curriculum. Residents were randomly divided into 2 groups: 1 group reviewed this online resource and the other did not. Pre- and post-tests consisted of videotaped microsurgical sessions in which the trainee performed "microsurgery" on 3 different models: latex glove, penrose drain, and the dorsal vessel of a chicken foot. The SMaRT (Stanford Microsurgery and Resident Training) scale, consisting of 9 categories graded on a 5-point Likert scale, was used to assess the trainees. Results were analyzed with ANOVA and Student t test, with P less than 0.05 indicating statistical significance. Seventeen residents participated in the study. The SMaRT scale adequately differentiated the performance of more experienced senior residents (PGY-4 to PGY-6, total average score=3.43) from less experienced junior residents (PGY-1 to PGY-3, total average score=2.10, P0.05). Additionally, junior residents who had access to our website showed a significant increase in their graded technical performance by 0.7 points when compared to residents who did not have access to the website who showed an improvement of only 0.2 points (P=0.01). Our SMaRT scale is valid and reliable in assessing the microsurgical skills of residents and other trainees. Current trainees are more likely to use self-directed on-line education because of its easy accessibility and interactive format. Our global rating scale can help ensure residents are achieving appropriate technical milestones.

Full Text Available RESUMO Em regiões áridas e semiáridas do planeta, a elevada demanda evaporativa e as características pedogenéticas dos solos, associadas a deficiências no sistema de drenagem de alguns perímetros irrigados, contribuem para um elevado potencial de salinização desses solos. Assim, constituíram objetivos deste estudo determinar o grau de salinização na área irrigada e avaliar o processo de acumulação de sais no período seco e o potencial de lixiviação destes pela água das chuvas no Perímetro Irrigado Califórnia, em Sergipe. Medidas da condutividade elétrica do extrato de saturação do solo (CEes, em dS m-1 a 25 ºC, foram efetuadas no início e final do período chuvoso dos anos de 2008 e 2009. A densidade amostral foi igualmente distribuída em toda área do Perímetro. Os dados foram submetidos à análise geoestatística e gerados mapas da distribuição espacial da CEes por meio do programa ArcGis®. Os valores médios da CEes obtidos revelaram que, apesar da prática de agricultura irrigada intensiva por longo período, o processo de acumulação de sais não foi significativo, tanto na camada superficial (0-0,20 m quanto em subsuperfície (0,20-0,40 m. Os valores médios da CEes em superfície variaram de 0,47 a 1,10 dS m-1, ficando abaixo de valores da salinidade limiar para a maioria das culturas anuais e perenes.

Full Text Available Lorsque le reggae émergea à la fin des années 1960, il eut un impact culturel considérable non seulement à la Jamaïque, mais à travers le monde. Le reggae a influencé les sociétés du monde entier, contribuant au développement de nouveaux mouvements contre-culturels, en particulier en Europe, aux États-Unis et en Afrique. En effet, à la fin des années 1960, il concourut à la naissance du mouvement skinhead au Royaume-Uni. Dans les années 1970, il eut un impact certain sur les cultures punk rock/ pop occidentales et inspira les premiers rappeurs aux États-Unis. Enfin, depuis la fin des années 1970, il influence également de nombreux chanteurs originaires d’Afrique, Alpha Blondy, Tiken Jah Fakoly et Lucky Dube étant de parfaits exemples. Ainsi, cet essai se propose d’étudier l’impact du reggae jamaïcain dans l’univers culturel mondial, notamment en Europe, aux États-Unis et en Afrique.When reggae emerged in the late 1960s, it came as a cultural bombshell not only to Jamaica but the whole world. Reggae has influenced societies throughout the world, contributing to the development of new counterculture movements, particularly in Europe, in the USA and Africa. Indeed, by the end of the 1960s, it participated in the birth of the skinhead movement in the UK. In the 1970s, it impacted on Western punk rock/ pop cultures and inspired the first rappers in the USA. Finally, since the late 1970s onwards, it has also influenced singers originating from Africa, Alpha Blondy, Tiken Jah Fakoly and Lucky Dube being perfect examples. Thus, my paper will examine the impact of Jamaican reggae music on the worldwide cultural universe, especially on Europe, the USA and Africa.

Knowledge of transport ventilator performance impacts patient safety. This study compared minute ventilation (V E ) of the MOVES and Uni-Vent 731 when ventilating the VentAid Training Test Lung with compliance (C) ranging from 0.02 to 0.10 L/cm H 2 O and three different airway resistances (R) (none, Rp5, or Rp20). Tidal volume (V T ) was 800 ± 25 mL. Respiratory rate was increased to ventilator's maximum or until auto-PEEP > 5 cm H 2 O. Respiratory parameters were recorded with the RSS 100HR Research Pneumotach. Data were reported as median (interquartile range). Peak inspiratory pressure (PIP) of the Uni-Vent and MOVES ranged from 22.3 (22.2-22.5) to 82.6 (82.2-83.2) and 20.8 (20.6-20.9) to 50.6 (50.2-50.9) cm H 2 O, respectively. V E of the Uni-Vent and MOVES ranged from 17.7 (17.7-17.7) to 31.5 (31.5-31.5) and 11.3 (10.5-11.3) to 20.2 (19.7-20.5) L/min, respectively. Linear regression demonstrated strong, negative correlation of V E with PIP for the MOVES (V E [L/min] = 26 - 0.31 × PIP [cm H 2 O], r = -0.97) but weak, positive correlation for the Uni-Vent (r = 0.05). Uni-Vent V E exceeded MOVES V E under each test condition (p = 0.0002). If patient V E requirements exceed those predicted by the MOVES regression equation, then using the Uni-Vent should be considered.

This questionnaire forms the basis of the quality assurance (QA) programme for the UK randomized Phase III study of the Stanford V regimen versus ABVD for treatment of advanced Hodgkin's disease to assess differences between participating centres in treatment planning and delivery of involved-field radiotherapy for Hodgkin's lymphoma The questionnaire, which was circulated amongst 42 participating centres, consisted of seven sections: target volume definition and dose prescription; critical structures; patient positioning and irradiation techniques; planning; dose calculation; verification; and future developments The results are based on 25 responses. One-third plan using CT alone, one-third use solely the simulator and the rest individualize, depending on disease site. Eleven centres determine a dose distribution for each patient. Technique depends on disease site and whether CT or simulator planning is employed. Most departments apply isocentric techniques and use immobilization and customized shielding. In vivo dosimetry is performed in 7 centres and treatment verification occurs in 24 hospitals. In conclusion, the planning and delivery of treatment for lymphoma patients varies across the country. Conventional planning is still widespread but most centres are moving to CT-based planning and virtual simulation with extended use of immobilization, customized shielding and compensation.

Hazards analysis for the E.O. Lawrence Berkeley National Laboratory x-ray absorption experiments to be performed at Stanford Synchrotron Radiation Laboratory

Edelstein, N.M.; Shuh, D.K.; Bucher, J.B.

The objective of this experiment is to determine the oxidation state(s) of neptunium (Np) in mouse skeleton and in soft tissue by X-ray Absorption Near Edge Structure (XANES). If Np is present in sufficient concentration, X-ray Absorption Fine Structure (XAFS) data will be obtained in order to further identify the Np species present. These data will be crucial in understanding the metabolic pathway of Np in mammals which will help in the design of reagents which can eliminate Np from mammals in the event of accidental exposure. It is proposed to run these experiments at the Standard Synchrotron Radiation Laboratory (SSRL). This laboratory is a DOE national user facility located at the Stanford Linear Accelerator Center (SLAC). The 237 Np nucleus decays by the emission of an alpha particle and this particle emission is the principal hazard in handling Np samples. This hazard is mitigated by physical containment of the sample which stops the alpha particles within the containment. The total amount of Np material that will be shipped to and be at SSRL at any one time will be less than 1 gram. This limit on the amount of Np will ensure that SLAC remains a low hazard, non-nuclear facility. The Np samples will be solids or Np ions in aqueous solution. The Np samples will be shipped to SSRL/SLAC OHP. SLAC OHP will inventory the samples and swipe the containers holding the triply contained samples, and then bring them to the SSRL Actinide trailer located outside building 131. The QA counting records from the samples, as measured at LBNL, will be provided to SSRL and SLAC OHP prior to the arrival of the samples at SLAC OHP. In addition, strict monitoring of the storage and experimental areas will be performed in accordance with SLAC/OHP radiation protection procedures to ensure against the release of contamination

Events in recent years have caused heightened concern about the security of weapons-usable nuclear material. The possibility of illicit trafficking in, or seizure of, such material, leading to nuclear terrorism, is a worry for all states and their citizens. And given the relatively small quantities required, material obtained in one part of the world could be made into a weapon in another and threaten lives in a third. It is truly a global problem. Since the beginning of the nuclear era, the physical protection of fissile material has been a responsibility of the individual states possessing the material. These states have different organizational approaches for providing physical protection; and while cognizant of recommended general standards, they tend to follow their own practices, shaped by custom, costs, and threat perception. Moreover, the existence of military as well as civil programs in some states adds another dimension to the physical protection issue. Because physical protection is a sovereign matter and not part of an international regime (except for transit of civil material across borders), there has been less attention in much of the world community to the issues of physical protection than to the other elements of nuclear safeguards and controls. (An important exception to this situation is the effort being made to assist the states of the former Soviet Union in the disposition of their weapons-usable nuclear materials.) The lack of a general dialog about a problem of growing concern motivated us to hold a three-day workshop at Stanford University to develop a better understanding of some of the important underlying questions and issues, and to undertake a comparative examination of states' approaches to physical protection. We were pleased to have knowledgeable participants from a number of the countries and regions where physical protection of fissile materials is, or will become, a day-to-day matter. The results of the workshop are reported in

At a time of growing concern over threats of terrorism, the security of nuclear and radioactive material is an urgent and serious issue. Working with a range of partners, the IAEA has put into place a multi-faceted Action Plan to help countries upgrade their capabilities. But more needs to be done to counter new types of threats. One particular area that needs to be strengthened is the physical protection of nuclear and radioactive material. The attacks of 11 September 2001 opened our eyes to i he urgent need to strengthen national physical protection (PP) practices for nuclear and other radioactive material. The principle that highly radioactive material will protect itself does not apply to the newest generation of terrorists. Existing PP systems were not designed to deal with the threat of suicidal terrorists commanding the numbers, skills, training, and resources available to those who carried out the attacks in the US. Moreover, because there are no mandatory international standards for domestic PP systems for nuclear or radioactive material, protection measures vary greatly from country to country. The IAEA recommended standards (Inference/225/Rev. 4) were not designed with the new terrorist threats in mind and national practices often fall short of even these recommendations. The result is inadequate protection against the new form of terrorism. Few argue the point that national physical protection practices for nuclear and other radioactive material need to be strengthened. This article summarizes a Stanford-Salzburg plan developed by experts from Stanford University's Center for International Security and Cooperation, (USA) and revised at the EU-Physical Protection NUMAT Conference in September 2002 in Salzburg, Austria. It includes six recommended elements to consider in addition to what the IAEA is now doing to improve PP practices around the world: Establish a global list of physical protection priorities; Create a multilateral security cooperation

To analyze the value of fractional flow reserve (FFR) measurement on endovascular therapy for patients with renal artery stenosis. Clinical data of 12 patients with Stanford B type aortic dissection complicated with renal blood flow injury in Anzhen hospital hospitalized from May 2013 to February 2014 were retrospectively analyzed. Renal artery angiography was performed and fractional flow reserve (FFR) was measured before Thoracic endovascular aortic repair. After operation, renal artery FFR was measured again, and renal artery stenting was performed in patients with FFR ≤ 0.90 or average pressure difference between proximal and distal of renal artery > 20 mmHg (1 mmHg = 0.133 kPa) and not applied for patients with FFR > 0.90.The patients were then subsequently followed up clinically. Kidney function were measured after 1 month, and contrast-enhanced ultrasonography data were obtained at 1 and 3 months later, respectively. The FFR of 1 patient was 0.90, while the FFR of other patients were less than 0.90 before thoracic endovascular aortic repair. After the procedure,the angiography showed that the blood flow of renal artery in 8 patients were fluency, and the FFR index was over 0.90. There were 4 patients with FFR less than 0.90. After renal artery stenting, the FFR of these 4 patients were all above 0.90. Compared with pre-procedure, blood urea nitrogen ((8.84 ± 3.99) mmol/L vs. (5.18 ± 1.69) mmol/L, P = 0.011) and uric acid ((359.3 ± 77.3) µmol/L vs. (276.9 ± 108.3) µmol/L, P = 0.008) decreased significantly after 1 month, and there was no significant difference in serum creatinine (P = 0.760). Contrast-enhanced ultrasonography results showed that blood flow of renal artery were fluency after 1 month and 3 months. In patients with aortic dissection complicating renal blood flow injury, the FFR measurement is meaningful in evaluating the blood flow status of target organs and guide the endovascular revascularization.

While such faculty-developed exercises have educational strengths, there are at least two major drawbacks to learning by this method: the number and diversity of cases is often limited; and students decrease their engagement with CBL cases as they grow accustomed to the teaching method. We sought to explore whether student case creation can address both of these limitations. We also compared student case creation to traditional clinical reasoning sessions in regard to tutorial group effectiveness, perceived gains in clinical reasoning, and quality of student–faculty interaction. Methods: Ten first-year medical students participated in a feasibility study wherein they worked in small groups to develop their own patient case around a preassigned diagnosis. Faculty provided feedback on case quality afterwards. Students completed pre- and post-self-assessment surveys. Students and faculty also participated in separate focus groups to compare their case creation experience to traditional CBL sessions. Results: Students reported high levels of team engagement

On Beyond Star Trek, the Role of Synthetic Biology in Nasa's Missions

Science.gov (United States)

Rothschild, Lynn J.

2016-01-01

The time has come to for NASA to exploit the nascent field of synthetic biology in pursuit of its mission, including aeronautics, earth science, astrobiology and notably, human exploration. Conversely, NASA advances the fundamental technology of synthetic biology as no one else can because of its unique expertise in the origin of life and life in extreme environments, including the potential for alternate life forms. This enables unique, creative "game changing" advances. NASA's requirement for minimizing upmass in flight will also drive the field toward miniaturization and automation. These drivers will greatly increase the utility of synthetic biology solutions for military, health in remote areas and commercial purposes. To this end, we have begun a program at NASA to explore the use of synthetic biology in NASA's missions, particularly space exploration. As part of this program, we began hosting an iGEM team of undergraduates drawn from Brown and Stanford Universities to conduct synthetic biology research at NASA Ames Research Center. The 2011 team (http://2011.igem.org/Team:Brown-Stanford) produced an award-winning project on using synthetic biology as a basis for a human Mars settlement and the 2012 team has expanded the use of synthetic biology to estimate the potential for life in the clouds of other planets (http://2012.igem.org/Team:Stanford-Brown; http://www.calacademy.org/sciencetoday/igem-competition/). More recent projects from the Stanford-Brown team have expanded our ideas of how synthetic biology can aid NASA's missions from "Synthetic BioCommunication" (http://2013.igem.org/Team:Stanford-Brown) to a "Biodegradable UAS (drone)" in collaboration with Spelman College (http://2014.igem.org/Team:StanfordBrownSpelman#SBS%20iGEM) and most recently, "Self-Folding Origami" (http://2015.igem.org/Team:Stanford-Brown), the winner of the 2015 award for Manufacturing.

D'où vient l'univers ? Et d'où vient même qu'il y ait un univers ? Aura-t-il une fin ? Pourquoi les humains y sont-ils apparus ? Si ces questions nous obsèdent depuis toujours, celle de l'origine demeure la plus mystérieuse, la plus vertigineuse, d'où la profusion de discours — mythologiques, religieux ou philosophiques — qui tentent d'y répondre. C'est grâce à la science, aux découvertes de Newton, Galilée, Edwin Hubble, Alexandre Friedmann et Georges Lemaître, qu'on peut retracer le grand récit de l'univers, remonter son histoire à 13,7 milliards d'années, jusqu'à cette phase très dense et très chaude qu'on a appelée le big bang. Mais celui-ci n'est pas pour autant, comme on l'a imaginé, cette explosion originelle qui aurait créé tout ce qui existe. Cet instant zéro, peut-on le décrire, le penser, raconter d'où il peut bien provenir ? Et d'où serait venu l'univers d'avant le big bang ? Mystère !

Reminiscing about thesis work with E T Jaynes at Stanford in the 1950s

Cummings, Frederick W.

2013-11-01

Abstract A short personal and historical account of the field of radiation interacting with (two-level) atoms is given. Subsequent to 1963, developments and extensions have been extensive and fruitful. One of the most fortunate changes in my life came in late 1957. I was looking for a thesis advisor, after two years of graduate course-work at Stanford. I chanced to see a notice of an upcoming lecture by a professor named Edwin T Jaynes. I could not understand from the announcement what he intended to talk about, but I was searching; I went to find out. That decision was a very lucky one. Ed was talking about a subject that inspired him then, and had been for many years, namely his concept of 'Max-Ent'. 'Maximum-Entropy' is a subject now close to my heart also. Ed's very-clear, well-thought-out papers, spread over many subsequent years, are transforming the field of probability (albeit too gradually) to the 'subjective' outlook of Bayes. (A recent book 'Maximum Entropy and Ecology' [1] will probably convert many nay-sayers to 'Max-Ent'.) I went into Ed's office (late 1957) and asked if I could work with him on a thesis. Did he have a problem for me? Yes, he did. Somewhat to my surprise, he asked me to look into the 'maser problem', involving a comparison of the semi-classical theory of radiation to a proper quantum treatment. To make a two-year story short, Ed's guidance was expert. (I imagine that if another of Ed's students (e.g. Joe Eberly) had come into his office fifteen minutes before me, the 'Jaynes-Cummings' (J-C) model would now perhaps be called otherwise, e.g., the 'J-E' model). In the two-year time frame (~1958-60), Ed had a number of other PhD dissertation students whom I knew; these included Joe Eberly, Doug Scalapino, Baldwin Robertson, Larry Davis and Mike Duggan. My thesis work under Ed reminds me of a story about Michelangelo and his famous 'Pieta'. Michelangelo was an old man about then, so he hired a young craftsman to do much of the physical

Monitoring Uranium Transformations Determined by the Evolution of Biogeochemical Processes: Design of Mixed Batch Reactor and Column Studies at Oak Ridge National Laboratory

Energy Technology Data Exchange (ETDEWEB)

Criddle, Craig S.; Wu, Weimin

2013-04-17

With funds provided by the US DOE, Argonne National Laboratory subcontracted the design of batch and column studies to a Stanford University team with field experience at the ORNL IFRC, Oak Ridge, TN. The contribution of the Stanford group ended in 2011 due to budget reduction in ANL. Over the funded research period, the Stanford research team characterized ORNL IFRC groundwater and sediments and set up microcosm reactors and columns at ANL to ensure that experiments were relevant to field conditions at Oak Ridge. The results of microcosm testing demonstrated that U(VI) in sediments was reduced to U(IV) with the addition of ethanol. The reduced products were not uraninite but were instead U(IV) complexes associated with Fe. Fe(III) in solid phase was only partially reduced. The Stanford team communicated with the ANL team members through email and conference calls and face to face at the annual ERSP PI meeting and national meetings.

Kadow, Christopher; Illing, Sebastian; Schartner, Thomas; Ulbrich, Uwe; Cubasch, Ulrich

2017-04-01

Operationalization processes are important for Weather and Climate Services. Complex data and work flows need to be combined fast to fulfill the needs of service centers. Standards in data and software formats help in automatic solutions. In this study we show a software solution in between hindcasts, forecasts, and validation to be operationalized. Freva (see below) structures data and evaluation procedures and can easily be monitored. Especially in the development process of operationalized services, Freva supports scientists and project partners. The showcase of the decadal climate prediction project MiKlip (fona-miklip.de) shows such a complex development process. Different predictions, scientists input, tasks, and time evolving adjustments need to be combined to host precise climate informations in a web environment without losing track of its evolution. The Freie Univ Evaluation System Framework (Freva - freva.met.fu-berlin.de) is a software infrastructure for standardized data and tool solutions in Earth system science. Freva runs on high performance computers to handle customizable evaluation systems of research projects, institutes or universities. It combines different software technologies into one common hybrid infrastructure, including all features present in the shell and web environment. The database interface satisfies the international standards provided by the Earth System Grid Federation (ESGF). Freva indexes different data projects into one common search environment by storing the meta data information of the self-describing model, reanalysis and observational data sets in a database. This implemented meta data system with its advanced but easy-to-handle search tool supports users, developers and their plugins to retrieve the required information. A generic application programming interface (API) allows scientific developers to connect their analysis tools with the evaluation system independently of the programming language used. Users of the

Full text: One objective of the Indian Ocean Experiment (INDOEX 1999) was to characterize the chemical composition of pollution outflow from South Asia. Real-time single particle analysis (ATOFMS, Univ. of California- Riverside), CO analysis (Nondispersive Infrared Gas Filter Correlation Photometer, Univ. of Maryland) and fast-response VOC measurements (PTR-MS, Univ. of Innsbruck) measurements were performed onboard the NOAA R/V Ronald H. Brown. Gas phase and aerosol chemical composition of encountered air parcels changed according to their geographic origin traced by backtrajectory analysis (continental air from Arabia and India; maritime air). The relative strength of combustion related pollution sources (biomass burning (BB) vs. fossil fuel (FF) combustion) was determined from the relative abundance of different tracers: acetonitrile (BB), CO (BB and FF), submicron particles containing carbon but no potassium (FF), submicron particles containing carbon and potassium (BB and coal combustion), submicron particles containing carbon, potassium and lithium (coal combustion). Arabian air clearly reflected the signature of fossil fuel combustion, while air from the Indian subcontinent was strongly influenced by biomass burning. (author)

The Lawrence Livermore National Laboratory (LLNL) encourages its employees to remotely attend classes given by Stanford University, University of California at Davis, and the National Technological University (NTU). To improve the quality of education for LLNL employees, we are cooperating with Stanford University in upgrading the Stanford Instructional Television Network (SITN). A dedicated high-speed communication link (Tl) between Stanford and LLNL will be used for enhanced services such as videoconferencing, real time classnotes distribution, and electronic distribution of homework assignments. The new network will also allow students to take classes from their offices with the ability to ask the professor questions via an automatically dialed telephone call. As part of this upgrade, we have also proposed a new videoconferencing based classroom environment where students taking remote classes would feel as though they are attending the live class. All paperwork would be available in near real time and students may converse normally with, and see, other remote students as though they were all in the same physical location. We call this the Virtual Classroom.'' 1 ref., 6 figs.

Loss of productivity at work, as a result of health problems, is becoming an issue of interest due to the high burden it represents in society. The measurement of such phenomenon can be made using generic and specific scales for certain diseases such as the Stanford Presenteeism Scale (SPS-6) and the Work Instability Scale for Ankylosing Spondylitis (AS-WIS), specific for patients with ankylosing spondylitis (AS). The aim of this study was to translate and perform a cross-cultural adaptation of SPS-6 and AS-WIS into Portuguese and check their psychometric properties. The study also aimed to evaluate the relationship between the general scores of the scales and the main sociodemographic and clinical data, lifestyles, and absenteeism in patients with AS and correlate these variables with SPS-6 and AS-WIS scales. A sample of 120 patients with AS and 80 workers at a university hospital was evaluated. The processes for the translation and cross-cultural adaptation of the instruments followed preestablished steps and rules presented in the literature. For the evaluation of measurement properties and correlations between scales, intra-class correlation coefficient (reproducibility analysis), Cronbach alpha (internal consistency), and Pearson correlation coefficient (validity) were employed. The inter-observer (0.986) and intra-observer (0.992) reproducibilities of the AS-WIS were shown to be high as well as the internal consistency (0.995). Similarly, the inter-observer reliability of SPS-6 was considered good (0.890), although it showed a poorer performance when considering the same observer (Pearson correlation coefficient = 0.675 and intra-class correlation = 0.656). Internal consistency, for the total number of items, as measured by Cronbach alpha, was 0.889. The validity of the scales was evaluated thru the comparison of the achieved scores with the results of the WLQ, SF-36, ASQoL, BASFI, BASDAI, HAQ-S, and SRQ-20 instruments. Correlations between loss of

We investigated the total numbers of cases of representative diseases, including acute myocardial infarction (AMI), unstable angina pectoris (uAP) and aortic dissection, treated at our coronary care unit and therapeutic strategies for them. Both AMI and uAP have been considered types of acute coronary syndrome with similar diagnostic criteria. We found, however, that the therapeutic strategies for these conditions differ slightly. Coronary bypass surgery was performed in a higher percentage of cases of uAP (7%) than of AMI (1%) because more time was available for surgery. The mortality rate was higher in cases of AMI. For aortic dissection, emergent surgery was performed in Stanford A cases with an open false lumen. Medical therapy was performed in Stanford B cases. These strategies were recommended in the guideline of the Japanese Society of Cardiology. In contrast, the strategy for Stanford A cases with intramural hematoma has been unclear. Medical control with careful follow-up computed tomography of the chest has been the preferred strategy for Stanford A cases with intramural hematoma in our coronary care unit. We have had good results with this method. (author)

Full Text Available Abstract Background Case management has emerged as a promising alternative approach to supplement traditional one-on-one sessions between patients and doctors for improving the quality of care in chronic diseases such as coronary heart disease (CHD. However, data are lacking in terms of its efficacy and cost-effectiveness when implemented in ethnic and low-income populations. Methods The Stanford and San Mateo Heart to Heart (HTH project is a randomized controlled clinical trial designed to rigorously evaluate the efficacy and cost-effectiveness of a multi-risk cardiovascular case management program in low-income, primarily ethnic minority patients served by a local county health care system in California. Randomization occurred at the patient level. The primary outcome measure is the absolute CHD risk over 10 years. Secondary outcome measures include adherence to guidelines on CHD prevention practice. We documented the study design, methodology, and baseline sociodemographic, clinical and lifestyle characteristics of 419 participants. Results We achieved equal distributions of the sociodemographic, biophysical and lifestyle characteristics between the two randomization groups. HTH participants had a mean age of 56 years, 63% were Latinos/Hispanics, 65% female, 61% less educated, and 62% were not employed. Twenty percent of participants reported having a prior cardiovascular event. 10-year CHD risk averaged 18% in men and 13% in women despite a modest low-density lipoprotein cholesterol level and a high on-treatment percentage at baseline. Sixty-three percent of participants were diagnosed with diabetes and an additional 22% had metabolic syndrome. In addition, many participants had depressed high-density lipoprotein (HDL cholesterol levels and elevated values of total cholesterol-to-HDL ratio, triglycerides, triglyceride-to-HDL ratio, and blood pressure. Furthermore, nearly 70% of participants were obese, 45% had a family history of CHD or

In May 2000, the radiology department at Stanford University Medical Center embarked on a five-year journey toward complete digitization. While the end goal was known, there was much less certainty about the steps involved along the way. Stanford worked with a team from GE Medical Systems to implement Six Sigma process improvement methodologies and related change management techniques. The methodical and evidence-based framework of Six Sigma significantly organized the process of "going digital" by breaking it into manageable projects with clear objectives. Stanford identified five key areas where improvement could be made: MR outpatient throughput, CT inpatient throughput, CT outpatient throughput, report turnaround time, and Lucile Packard Children's Hospital CR/Ortho throughput and digitization. The CT project is presented in this article. Although labor intensive, collecting radiology data manually is often the best way to obtain the level of detail required, unless there is a robust RIS in place with solid data integrity. To gather the necessary information without unduly impacting staff and workflow at Stanford, the consultants working onsite handled the actual observation and recording of data. Some of the changes introduced through Six Sigma may appear, at least on the surface, to be common sense. It is only by presenting clear evidence in terms of data, however, that the improvements can actually be implemented and accepted. By converting all appointments to 30 minutes and expanding hours of operation, Stanford was able to boost diagnostic imaging productivity, volume and revenue. With the ability to scan over lunch breaks and rest periods, potential appointment capacity increased by 140 CT scans per month. Overall, the CT project increased potential for outpatient appointment capacity by nearly 75% and projected over $1.5 million in additional annual gross revenue.

2018-02-12

Herein we summarize the results of an investigation dealing with the concentrations and inventories of strategic, critical and valuable materials (SCVM) in produced fluids from geothermal and hydrocarbon reservoirs (50-250° C) in Nevada and Utah. Water samples were collected from thirty-four production wells across eight geothermal fields, the Uinta Basin oil/gas province in northeast Utah, and the Covenant oil field in southwestern Utah; additional water samples were collected from six hot springs in the Sevier Thermal Belt in southwestern Utah. Most SCVM concentrations in produced waters range from <0.1 to 100 µg/kg; the main exception is lithium, which has concentrations that range from <1000 to 25,000 ug/kg. Relatively high concentrations of gallium, germanium, scandium, selenium, and tellurium are measured too. Geothermal waters contain very low concentrations of REEs, below analytical detections limits (0.01 µg/kg), but the concentrations of lanthanum, cerium, and europium range from 0.05 to 5 µg/kg in Uinta basin waters. Among the geothermal fields, the Roosevelt Hot Spring reservoir appears to have the largest inventories of germanium and lithium, and Patua appears to have the largest inventories of gallium, scandium, selenium, and tellurium. By comparison, the Uinta basin has larger inventories of gallium. The concentrations of gallium, germanium, lithium, scandium, selenium, and tellurium in produced waters appear to be partly related to reservoir temperature and concentrations of total dissolved salts. The relatively high concentration and large inventory of lithium occurring at Roosevelt Hot Springs may be related to granitic-gneissic crystalline rocks, which host the reservoir. Analyses of calcite scales from Dixie Valley indicate enrichments in cobalt, gallium, gold, palladium, selenium and tellurium, and these metals appear to be depositing at deep levels in production wells due to boiling. Comparisons with SCVM mineral deposits suggest that brines in sedimentary basins, or derived from lacustrine evaporites, enable aqueous transport of gallium, germanium, and lithium.

Water quality issues associated with agricultural drainage in semiarid regions

Science.gov (United States)

Sylvester, Marc A.

High incidences of mortality, birth defects, and reproductive failure in waterfowl using Kesterson Reservoir in the San Joaquin Valley, Calif., have occurred because of the bioaccumulation of selenium from irrigation drainage. These circumstances have prompted concern about the quality of agriculture drainage and its potential effects on human health, fish and wildlife, and beneficial uses of water. The U.S. Geological Survey (USGS) and Lawrence Berkeley Laboratory, University of California (Berkeley, Calif.) organized a 1-day session at the 1986 AGU Fall Meeting in San Francisco, Calif., to provide an interdisciplinary forum for hydrologists, geochemists, and aquatic chemists to discuss the processes controlling the distribution, mobilization, transport, and fate of trace elements in source rocks, soils, water, and biota in semiarid regions in which irrigated agriculture occurs. The focus of t h e session was the presentation of research results on the source, distribution, movement, and fate of selenium in agricultural drainage.

To investigate the effects of sleep extension over multiple weeks on specific measures of athletic performance as well as reaction time, mood, and daytime sleepiness. Stanford Sleep Disorders Clinic and Research Laboratory and Maples Pavilion, Stanford University, Stanford, CA. Eleven healthy students on the Stanford University men's varsity basketball team (mean age 19.4 ± 1.4 years). Subjects maintained their habitual sleep-wake schedule for a 2-4 week baseline followed by a 5-7 week sleep extension period. Subjects obtained as much nocturnal sleep as possible during sleep extension with a minimum goal of 10 h in bed each night. Measures of athletic performance specific to basketball were recorded after every practice including a timed sprint and shooting accuracy. Reaction time, levels of daytime sleepiness, and mood were monitored via the Psychomotor Vigilance Task (PVT), Epworth Sleepiness Scale (ESS), and Profile of Mood States (POMS), respectively. Total objective nightly sleep time increased during sleep extension compared to baseline by 110.9 ± 79.7 min (P sleep extension (16.2 ± 0.61 sec at baseline vs. 15.5 ± 0.54 sec at end of sleep extension, P sleep extension (P sleep extension indicate that optimal sleep is likely beneficial in reaching peak athletic performance.

Large-scale academic achievement testing of deaf and hard-of-hearing students: past, present, and future.

Qi, Sen; Mitchell, Ross E

2012-01-01

The first large-scale, nationwide academic achievement testing program using Stanford Achievement Test (Stanford) for deaf and hard-of-hearing children in the United States started in 1969. Over the past three decades, the Stanford has served as a benchmark in the field of deaf education for assessing student academic achievement. However, the validity and reliability of using the Stanford for this special student population still require extensive scrutiny. Recent shifts in educational policy environment, which require that schools enable all children to achieve proficiency through accountability testing, warrants a close examination of the adequacy and relevance of the current large-scale testing of deaf and hard-of-hearing students. This study has three objectives: (a) it will summarize the historical data over the last three decades to indicate trends in academic achievement for this special population, (b) it will analyze the current federal laws and regulations related to educational testing and special education, thereby identifying gaps between policy and practice in the field, especially identifying the limitations of current testing programs in assessing what deaf and hard-of-hearing students know, and (c) it will offer some insights and suggestions for future testing programs for deaf and hard-of-hearing students.

EC-Marie Curie Initial Training Networks (ITN) projects aim to improve the career perspectives of young generations of researchers. Institutions from both academic and industry sectors form a collaborative network to recruit research fellows and provide them with opportunities to undertake research in the context of a joint research training program. In this frame, TOPOMOD - one of the training activities of EPOS, the new-born European Research Infrastructure for Geosciences - is a funded ITN project designed to investigate and model how surface processes interact with crustal tectonics and mantle convection to originate and develop topography of the continents over a wide range of spatial and temporal scales. The multi-disciplinary approach combines geophysics, geochemistry, tectonics and structural geology with advanced geodynamic numerical/analog modelling. TOPOMOD involves 8 European research teams internationally recognized for their excellence in complementary fields of Earth Sciences (Roma TRE, Utrecht, GFZ, ETH, Cambridge, Durham, Rennes, Barcelona), to which are associated 5 research institutions (CNR-Italy, Univ. Parma, Univ. Lausanne, Univ. Montpellier, Univ. Mainz) , 3 high-technology enterprises (Malvern Instruments, TNO, G.O. Logical Consulting) and 1 large multinational oil and gas company (ENI). This unique network places emphasis in experience-based training increasing the impact and international visibility of European research in modeling. Long-term collaboration and synergy are established among the overmentioned research teams through 15 cross-disciplinary research projects that combine case studies in well-chosen target areas from the Mediterranean, the Middle and Far East, west Africa, and South America, with new developments in structural geology, geomorphology, seismology, geochemistry, InSAR, laboratory and numerical modelling of geological processes from the deep mantle to the surface. These multidisciplinary projects altogether aim to

Highlights of progress achieved in the program of thermochemical conversion of biomass into clean fuels during 1983 are summarized. Gasification research projects include: production of a medium-Btu gas without using purified oxygen at Battelle-Columbus Laboratories; high pressure (up to 500 psia) steam-oxygen gasification of biomass in a fluidized bed reactor at IGT; producing synthesis gas via catalytic gasification at PNL; indirect reactor heating methods at the Univ. of Missouri-Rolla and Texas Tech Univ.; improving the reliability, performance, and acceptability of small air-blown gasifiers at Univ. of Florida-Gainesville, Rocky Creek Farm Gasogens, and Cal Recovery Systems. Liquefaction projects include: determination of individual sequential pyrolysis mechanisms at SERI; research at SERI on a unique entrained, ablative fast pyrolysis reactor for supplying the heat fluxes required for fast pyrolysis; work at BNL on rapid pyrolysis of biomass in an atmosphere of methane to increase the yields of olefin and BTX products; research at the Georgia Inst. of Tech. on an entrained rapid pyrolysis reactor to produce higher yields of pyrolysis oil; research on an advanced concept to liquefy very concentrated biomass slurries in an integrated extruder/static mixer reactor at the Univ. of Arizona; and research at PNL on the characterization and upgrading of direct liquefaction oils including research to lower oxygen content and viscosity of the product. Combustion projects include: research on a directly fired wood combustor/gas turbine system at Aerospace Research Corp.; adaptation of Stirling engine external combustion systems to biomass fuels at United Stirling, Inc.; and theoretical modeling and experimental verification of biomass combustion behavior at JPL to increase biomass combustion efficiency and examine the effects of additives on combustion rates. 26 figures, 1 table.

1980-12-18

INTRODUCTION TO THE PROCEEDINGS OF THE SIXTH GEOTHERMAL RESERVOIR ENGINEERING WORKSHOP, STANFORD GEOTHERMAL PROGRAM Henry J. Ramey, Jr., and Paul Kruger Co-Principal Investigators Ian G. Donaldson Program Manager Stanford Geothermal Program The Sixth Workshop on Geothermal Reservoir Engineering convened at Stanford University on December 16, 1980. As with previous Workshops the attendance was around 100 with a significant participation from countries other than the United States (18 attendees from 6 countries). In addition, there were a number of papers from foreign contributors not able to attend. Because of the success of all the earlier workshops there was only one format change, a new scheduling of Tuesday to Thursday rather than the earlier Wednesday through Friday. This change was in general considered for the better and will be retained for the Seventh Workshop. Papers were presented on two and a half of the three days, the panel session, this year on the numerical modeling intercomparison study sponsored by the Department of Energy, being held on the second afternoon. This panel discussion is described in a separate Stanford Geothermal Program Report (SGP-TR42). This year there was a shift in subject of the papers. There was a reduction in the number of papers offered on pressure transients and well testing and an introduction of several new subjects. After overviews by Bob Gray of the Department of Energy and Jack Howard of Lawrence Berkeley Laboratory, we had papers on field development, geopressured systems, production engineering, well testing, modeling, reservoir physics, reservoir chemistry, and risk analysis. A total of 51 papers were contributed and are printed in these Proceedings. It was, however, necessary to restrict the presentations and not all papers printed were presented. Although the content of the Workshop has changed over the years, the format to date has proved to be satisfactory. The objectives of the Workshop, the bringing together of

Multivers mondes possibles de l'astrophysique, de la philosophie et de l'imaginaire

Barrau, Aurélien; Kistler, Max; Uzan, Jean-Philippe

2010-01-01

Et si notre Univers n'était qu un parmi d'autres ? Cette idée d'univers multiples, qui est envisagée depuis l'Antiquité, n'est entrée que récemment - et avec fracas - dans le champ de la science. Si l'hypothèse fascine, elle n'en est pas moins dérangeante : comment se formeraient ces mondes invisibles ? Auraient-ils les mêmes lois physiques ? Peut-on tester et réfuter leur existence ? Une telle hypothèse est-elle vraiment scientifique ? Faut-il en rester aux critères de scientificité traditionnels ou ouvrir la porte aux mondes possibles de l'astrophysique, de la philosophie et de l'imaginaire ? Un cosmologiste, un physicien théoricien, un philosophe et un historien de la science-fiction nous invitent à nous immerger au coeur de la physique théorique, à révolutionner la manière de concevoir ce qu'est une théorie physique signifiante, à extrapoler les lois de la nature pour décrire d'autres univers. Ils nous montrent qu'il y a une multiplicité de «manières de faire des mondes» et que n...

Écrire l'histoire de l'Univers, tel est l'objectif commun des physiciens des particules et des astrophysiciens. Pour y parvenir, deux approches s'épaulent : la voie de l'infiniment petit, que l'on emprunte via de gigantesques accélérateurs de particules, et celle de l'infiniment grand, dont le laboratoire est l'Univers. Un Univers qui est bien loin d'avoir livré tous ses secrets. On connaît à peine 4,8 % de la matière qui le constitue, le reste étant composé de matière noire (25,8 %) et d'énergie noire (69,4 %), toutes deux de nature inconnue. Et si la récente découverte du boson de Higgs valide le Modèle standard de la physique des particules, celui-ci est toujours incomplet et doit être étendu à ou dépassé. Est-on arrivé au bout du jeu de poupées russes de la matière ? Quelles sont les particules manquantes ? Faut-il revoir les lois fondamentales ? Quels instruments faut-il mettre en œuvre pour accéder à cette « nouvelle physique » ? Comment parler de Super Big Science aux citoye...

The titular stuffs, silver and fur, of the two books reviewed here reveal the material basis of the books’ arguments. Nevertheless, the primary resources exploited directly by authors Kwangmin Kim and Jonathan Schlesinger were the ink and paper of the archival documents in languages other than Chinese, most especially in Manchu, that they consulted in the course of their research. In these books’ reliance on non-Chinese sources, Borderland Capitalism and A World Trimmed with Fur are representative of a growing body of Qing scholarship in English that delineates the empire within multilingual parameters that do not marginalize its borderlands. Instead, in these works, borderlands are integrated with central concerns of imperial commerce and imperial identity, as well as linked solidly to pervasive global trade patterns stretching well beyond the already-vast bounds of the Qing Empire. This reorientation is made possible largely because detailed documentation of local borderland dynamics exists, largely in Manchu, for periods of their formation, consolidation, and onset of decline from the mid-seventeenth into the early nineteenth centuries...

Alpha decay calculations with a new formula

International Nuclear Information System (INIS)

Akrawy, D T; Poenaru, D N

2017-01-01

A new semi-empirical formula for calculations of α  decay half-lives is presented. It was derived from the Royer relationship by introducing new parameters which are fixed by fit to a set of experimental data. We are using three sets: set A with 130 e–e (even–even), 119 e–o (even–odd), 109 o–e, and 96 o–o, set B with 188 e–e, 147 e–o, 131 o–e and 114 o–o, and set C with 136 e–e, 84 e–o, 76 o–e and 48 o–o alpha emitters. A comparison of results obtained with the new formula (newF) and the following well known relationships: semiempirical relationship based on fission theory (semFIS), analytical superasymmetric fission (ASAF) model and universal formula (UNIV) made in terms of rms standard deviation. We also introduced a weighted mean value of this quantity, allowing us to compare the global properties of a given model. For set B the order of the four models is the following: semFIS, UNIV, newF and ASAF. Nevertheless for even–even alpha emitters, UNIV gives the second best result after semFIS, and for odd–even parents the second is newF. Despite its simplicity in comparison with semFIS, newF, presented in this article, behaves quite well, competing with the other well known relationships. (paper)

Martz, Joseph C. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

2014-01-07

Stockpile stewardship is a topic dear to my heart. I’ve been fascinated by it, and I’ve lived it—mostly on the technical side but also on the policy side from 2009 to 2010 at Stanford University as a visiting scholar and the inaugural William J. Perry Fellow. At Stanford I worked with Perry, former secretary of defense, and Sig Hecker, former Los Alamos Lab director (1986–1997), looking at nuclear deterrence, nuclear policy, and stockpile stewardship and at where all this was headed.

The 40th anniversary of the discovery of NMR-chemical shift and nuclear spin-spin coupling

After the discovery of NMR Phenomenon in the physics laboratories of E.M.Purcell at Harvard and F.Bloch at Stanford in 1946, W.G.Proctor and F.C.Yu made the successful discovery of NMR-chemical shift and nuclear spin-spin coupling at Stanford in 1950, Which brought NMR spectroscopy from the physics laboratory to the laboratories of many different fields. This is worth memorizing. Retrospecting the past 40 years, it is sure that chemical shift theory will be much more prosperous prospects

Under SLAC's supervision, the SPEAR ring and injector system were operated for the first time in a truly dedicated mode for user experimentation. In October, SSRL became a division of SLAC. With that organizational change, SSRL became fully responsible for the operation, maintenance and improvement of SPEAR and its injection accelerators. At the same time, other radiation sources were studied. Free electron lasers providing enormous peak brightnesses and time average brightnesses about two orders of magnitude greater than the machines presently being constructed or commissioned were the object of one line of analysis. Ultra-short pulse beams at lower photons energies were also studied. These, as well, are described in Chapter 2. Significant gains were also made on the beam lines. Perhaps the most dramatic was the introduction of YB 66 crystals into the Jumbo monochromator, as described in Chapter 3. Looking to the future, SSRL held a workshop on Fourth Generation Light Sources in February and two workshops in conjunction with the Users Meeting. The impact of the high quality running is demonstrated by the many high quality experimental programs performed on SPEAR during the year. These are described in Chapter 6

The SSRL facility delivered 89% of the scheduled user beam to 25 experimental stations during 6.5 months of user running. Users from private industry were involved in 31% of these experiments. The SPEAR accelerator ran very well with no major component failures and an unscheduled down time of only 2.9%. In addition to this increased reliability, there was a significant improvement in the stability of the beam. The enhancements to the SPEAR orbit as part of a concerted three-year program were particularly noticeable to users. The standard deviation of beam movement (both planes) in the last part of the run was 80 microns, major progress toward the ultimate goal of 50-micron stability. This was a significant improvement from the previous year when the movement was 400 microns in the horizontal and 200 microns in the vertical. A new accelerator Personal Protection System (PPS), built with full redundancy and providing protection from both radiation exposure and electrical hazards, was installed in 1994. It is not possible to describe in this summary all of the scientific experimentation which was performed during the run. However, the flavor of current research projects and the many significant accomplishments can be realized by the following highlights: A multinational collaboration performed several experiments involving x-ray scattering from nuclear resonances; Studies related to nuclear waste remediation by groups from Los Alamos National Laboratory and Pacific Northwest Laboratories continued in 1994; Diffraction data sets for a number of important protein crystals were obtained; During the past two years a collaboration consisting of groups from Hewlett Packard, Intel, Fisons Instruments and SSRL has been exploring the utility of synchrotron radiation for total reflection x-ray fluorescence (TRXRF); and High-resolution angle-resolved photoemission experiments have continued to generate exciting new results from highly correlated and magnetic materials

Preparing Future Geoscientists at the Critical High School-to-College Junction: Project METALS and the Value of Engaging Diverse Institutions to Serve Underrepresented Students

Science.gov (United States)

White, L. D.; Maygarden, D.; Serpa, L. F.

2015-12-01

Since 2010, the Minority Education Through Traveling and Learning in the Sciences (METALS) program, a collaboration among San Francisco State Univ., the Univ. of Texas at El Paso, the Univ. of New Orleans, and Purdue Univ., has created meaningful, field-based geoscience experiences for underrepresented minority high school students. METALS activities promote excitement about geoscience in field settings and foster mutual respect and trust among participants of different backgrounds and ethnicities. These gains are strengthened by the collective knowledge of the university partners and by faculty, graduate and undergraduate students, scientists, and science teachers who guide the field trips and who are committed to encouraging diversity in the geosciences. Through the student experiences it provides, METALS has helped shape and shift student attitudes and orientation toward geoscience, during and beyond their field experience, just as these students are poised at the critical juncture from high school to college. A review of the METALS findings and summative evaluation shows a distinct pattern of high to moderately high impact on most students in the various cohorts of the program. METALS, overall, was perceived by participants as a program that: (1) opens up opportunities for individuals who might not typically be able to experience science in outdoor settings; (2) offers high-interest geology content in field contexts, along with social and environmental connections; (3) promotes excitement about geology while encouraging the development of mutual respect, interdependence, and trust among individuals of different ethnicities; (4) influences the academic choices of students, in particular their choice of major and course selection in college. Summative data show that multiple aspects of this program were highly effective. Cross-university collaborations create a dynamic forum and a high-impact opportunity for students from different backgrounds to meet and develop

Gravity Probe B Number 4 Gyro Inspected

Science.gov (United States)

2000-01-01

The Gravity Probe B (GP-B) is the relativity experiment developed at Stanford University to test two extraordinary predictions of Albert Einstein's general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth's rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. In this photograph, Stanford engineer, Chris Gray, is inspecting the number 4 gyro under monochromatic light. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies that are already enlivening other branches of science and engineering. Launched April 20, 2004 , the GP-B program was managed for NASA by the Marshall Space Flight Center. Development of the GP-B is the responsibility of Stanford University along with major subcontractor Lockheed Martin Corporation. (Image credit to Russ Leese, Stanford University.)

A Simple Correlation for Neutron Capture Rates from Nuclear Masses

Energy Technology Data Exchange (ETDEWEB)

Couture, Aaron Joseph [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

2018-01-30

Recent studies of neutron capture performed at LANL have revealed a previously unrecognized connection between nuclear masses and the average neutron capture cross section. A team of three scientists from Los Alamos (P-27), Yale Univ., and Istanbul Univ. (Turkey) recently discovered this connection and have published their results as a Rapid Communication in Physical Review C. Neutron capture is a reaction in which a free neutron is absorbed by the nucleus, keeping the element unchanged, but changing isotopes. This reaction is typically exothermic. As a result, the reaction can proceed even when many other reaction channels are closed. In an astrophysical environment, this means that neutron capture is the primary mechanism by which all of the elements with atomic number greater than nickel are produced is neutron capture.

Magnetic monopoles: a status report

International Nuclear Information System (INIS)

Carrigan, R.A. Jr.; Trower, W.P.

1983-03-01

A solitary, uncorroborated Stanford candidate event is the only evidence that magnetic monpoles derives from Dirac's assertion that monopoles could explain charge quantization and the 't Hooft-Polyakov demonstration that monopoles are an inevitable consequence of many gauge theories currently being used to unify the electroweak (photon-lepton) and nuclear (quark) interactions. The monopole abundance implied by the Stanford event is in clear contradiction to bounds on their number from astronomical data. Fortunately, the already considerable and expanding arsenal of detection techniques are being fashioned to experimentally test the many open questions surrounding monopoles

Monochromatization of synchrotron radiation for studies in photoelectron spectroscopy

Synchrotron radiation provides a tunable photon source which bridges the wavelength gap between HeI and AlKsub(α) radiation sources in photoelectron spectroscopy. The essential component for using synchrotron radiation is a monochromator. Some design features of the monochromators fabricated at Stanford, U.S.A., and Orsay, France, are described. The Stanford monochromator is a silicon crystal monochromator yielding 8 keV X-ray beam and is used with SPEAR storage ring facility, while the Orsay monochromator is a grazing incidence grating monochromator used for UPS studies.

Nineteenth workshop on geothermal reservoir engineering: Proceedings

Energy Technology Data Exchange (ETDEWEB)

Ramey, H.J. Jr.; Horne, R.J.; Kruger, P.; Miller, F.G.; Brigham, W.E.; Cook, J.W. (Stanford Geothermal Program)

1994-01-20

PREFACE The Nineteenth Workshop on Geothermal Reservoir Engineering was held at Stanford University on January 18-20, 1994. This workshop opened on a sad note because of the death of Prof. Henry J. Ramey, Jr. on November 19, 1993. Hank had been fighting leukemia for a long time and finally lost the battle. Many of the workshop participants were present for the celebration of his life on January 21 at Stanford's Memorial Church. Hank was one of the founders of the Stanford Geothermal Program and the Geothermal Reservoir Engineering Workshop. His energy, kindness, quick wit, and knowledge will long be missed at future workshops. Following the Preface we have included a copy of the Memorial Resolution passed by the Stanford University Senate. There were one hundred and four registered participants. Participants were from ten foreign countries: Costa Rica, England, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, Philippines and Turkey. Workshop papers described the performance of fourteen geothermal fields outside the United States. Roland N. Home opened the meeting and welcomed the visitors to the campus. The key note speaker was J.E. ''Ted'' Mock who gave a presentation about the future of geothermal development. The banquet speaker was Jesus Rivera and he spoke about Energy Sources of Central American Countries. Forty two papers were presented at the Workshop. Technical papers were organized in twelve sessions concerning: sciences, injection, production, modeling, and adsorption. Session chairmen are an important part of the workshop and our thanks go to: John Counsil, Mark Walters, Dave Duchane, David Faulder, Gudmundur Bodvarsson, Jim Lovekin, Joel Renner, and Iraj Ershaghi. The Workshop was organized by the Stanford Geothermal Program faculty, staff, and graduate students. We wish to thank Pat Ota, Ted Sumida, and Terri A. Ramey who also produces the Proceedings Volumes for publication. We owe a great deal of thanks to our students who

L’univers des anciens prisonniers politiques en Syrie

Full Text Available Les prisonniers politiques furent très nombreux en Syrie des années 1970 jusqu’à leur libération progressive de 1991 à 2005. Si leur conditions de vie en prison, les interrogatoires et la torture sont parfois abordés par les ex-prisonniers, leur existence après la prison ne semble susciter aucun intérêt. Cet article se propose de commencer à combler cette lacune, en analysant les facteurs qui pèsent sur la vie post-carcérale. Les conditions et la durée d’incarcération, le milieu social et affectif trouvé à la sortie, les réseaux de relation, la chance de trouver un travail et des moyens de subsistance sont autant d’éléments qui créent des conditions plus ou moins favorables à la réinsertion. Les ex-prisonniers politiques rencontrent quoi qu’il en soit d’énormes difficultés, y compris à gérer leur propre image. Des initiatives commencent à se faire jour pour tenter d’obtenir la réhabilitation et des dédommagements pour ces individus injustement brisés.
