Using A Nameserver to Enhance Control System Efficiency

The Thomas Jefferson National Accelerator Facility (Jefferson Lab) control system uses a nameserver to reduce system response time and to minimize the impact of client name resolution on front-end computers. The control system is based on the Experimental Physics and Industrial Control System (EPICS), which uses name-based broadcasts to initiate data communication. By default, when EPICS process variables (PV) are requested by client applications, all front-end computers receive the broadcasts and perform name resolution processing against local channel name lists. The nameserver is used to offload the name resolution task to a single node. This processing, formerly done on all front-end computers, is now done only by the nameserver. In a control system with heavily loaded front-end computers and high peak client connection loads, a significant performance improvement is seen. This paper describes the name server in more detail, and discusses the strengths and weaknesses of making name resolution a centralized service.Comment: ICALEPCS 200

Avoidance of Disclaimer by Action for Fraudulent Misrepresentation

The recent Washington Supreme Court decision in the case of Nyquist v. Foster dealt with the troublesome problem of a chattel vendee\u27s right to rescind upon proof of the vendor\u27s fraudulent misrepresentation in a sales situation where the contract of sale contains a disclaimer clause. The purpose of the disclaimer clause is to prevent a suit by the purchaser upon a theory of either express or implied warranty. The common practice of inserting such a clause in a contract of sale makes any ruling upon its effective scope in limiting a vendee\u27s possible right of action a matter of importance to lawyers and businessmen

Evaluation of a new trauma-related drinking to cope measure: Latent structure and heritability

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) commonly co-occur, share latent genetic risk, and are associated with many negative public health outcomes. Via a self-medication framework, trauma-related drinking to cope (TRD), an unexplored phenotype to date, may help explain why these two disorders co-occur, thus serving as an essential target for treatment and prevention efforts. This study sought to create a novel measure of TRD and to investigate its indirect influences on the association between PTSD and AUD, as well as its potential shared molecular genetic risk with PTSD in a genetically-informative study of college students. A sample of 1,896 undergraduate students with a history of trauma and alcohol use provided genotypic data and completed an online assessment battery. The psychometric properties of TRD and how it relates to relevant constructs were examined using descriptive statistics and structural equation modeling. Results of a correlated multiple mediator model indicated that, while accounting for the effects of generalized drinking motives, TRD partially mediated the relation between PTSD and alcohol use problems (β = 0.213, p \u3c .001), consistent with the self-medication hypothesis, and that this relationship was stronger for males (β = 0.804, p \u3c .001) than for females (β = 0.463, p \u3c .001). Results were substantiated using longitudinal data. Genotypic analyses to be presented will include univariate genome wide complex trait analyses (GCTA) to establish SNP-based heritability associated with TRD and PTSD, separately, as well as bivariate GCTA to examine potential overlap in heritability between TRD and PTSD.https://scholarscompass.vcu.edu/gradposters/1047/thumbnail.jp

Production and state-selective detection of ultracold, ground state RbCs molecules

Using resonance-enhanced two-photon ionization, we detect ultracold, ground-state RbCs molecules formed via photoassociation in a laser-cooled mixture of 85Rb and 133Cs atoms. We obtain extensive bound-bound excitation spectra of these molecules, which provide detailed information about their vibrational distribution, as well as spectroscopic data on the RbCs ground a^3\Sigma^+ and excited (2)^3\Sigma^+, (1)^1\Pi states. Analysis of this data allows us to predict strong transitions from observed excited levels to the absolute vibronic ground state of RbCs, potentially allowing the production of stable, ultracold polar molecules at rates as large as 10^7 s^{-1}

Some Reflections on the Economic Consequences of the Cancellation of a Contract in French Law

French law has no general rules on restitution. However, it does have specific restitutionary principles for different areas of law. This article, originally written in French, considers the restitutionary principles that apply in the field of contract

Staffing National Health Care Reform: A Role for Advanced Practice Nurses

Expanding access and coverage while containing costs can only be accomplished by getting more health care value for our money. Two facts about our current system make this seem possible. First, the currently uninsured are not costless. Providing stop-gap health care to those who lack health insurance is extremely expensive -- people without formal coverage cannot afford preventive services, delay treatment of illness and face substantial barriers to reaching appropriate providers. When they receive care, it is often degrading, usually complicated and costly, and more than occasionally too late. The cost of this uncompensated care is borne by all of us in higher prices for our own health insurance, in taxes and in the federal deficit. Moreover, this cost is not distributed evenly, and reduces our ability to determine whether the price of our own health care is fair. In addition, the need for last resort care for the uninsured locks us into continued support of aging public health facilities that are often underequipped and inefficient. The second characteristic of our current system is that the utilization of health care services is tremendously wasteful. Gaps in our knowledge as to what works and what doesn\u27t, fee-for-service payment that creates incentives to do more rather than less, lack of coordination between providers, high patient expectations and fear of malpractice litigation all predispose to overutilization. We are fascinated by expensive technology, and use it uncritically. Moreover, these influences have elevated the illness-based model of care over the health-based model. As a result, a disproportionate amount of our health care budget is devoted to the treatment of acute illness, often in institutional settings, rather than to primary, preventive and long-term community and home-based care. These observations suggest a prescription for change. Improving the cost effectiveness of health care delivery -- in particular by emphasizing preventive and primary care and adopting a more discriminating approach to the use of expensive, referral services -- can free up the resources needed to include all Americans in the health care system. This effort must be undertaken by health care providers, by communities and by government
