Continuous vibration monitoring system at an operating microelectronics fabrication plant

Various construction activities were planned in an area next to Intel''s sub-micron microelectronics facility in Santa Clara. We needed to develop a system to ensure the continued operation of the process equipment during construction without any yield problems due to transmission of construction-related vibrations. A computer-based vibration monitoring system was devised and built which provides continuous measurements and is suitable for ''interactive'' as well as for ''archive'' use. In ''interactive'' use, alarm levels are set at two threshold values which were chosen from operating fabrication plant characteristics. Continuous data generation and its analysis with respect to the construction related activities gives a clear indication of harmful construction activities and equipment. The transmission ability of vibration through the existing type of soil and isolated grade slab construction is also studied. The dampening or amplifications of vibration levels with respect to location and distance from the source has been characterized and evaluated.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.

Availability of unrelated donors for hematopoietic stem cell transplantation for hemoglobinopathies

Hematopoietic stem cell transplantation (HSCT) is the only curative option for patients with hemoglobinopathies. However, fewer than 30% of individuals will have an HLA-identical sibling. Improvement in outcomes after HSCT using unrelated donors (URD), and the development of novel nontoxic preparative regimens may make URD HSCT an option for hemoglobinopathy patients who do not have an HLA-identical sibling donor. The National Marrow Donor Program (NMDP) maintains a Registry of 4 million volunteer donors, and facilitates URD HSCT for patients with life-threatening blood diseases. In light of the increased representation of minorities in the NMDP registry, donor searches were run in April 2001 for a cohort of 272 thalassemia patients and 77 sickle cell disease (SCD) patients for whom searches had been submitted between 1989 and 2001 in order to determine the current likelihood of finding a potential donor of hematopoietic stem cells for hemoglobinopathy patients. About 59.7% SCD patients 80.2% thalassemia patients will find at least one potential 6/6 HLA matched donor or umbilical cord blood (UCB) unit. All patients will find at least one donor or UCB that is a potential 5/6 HLA match. In conclusion the majority of hemoglobinopathy patients will find at least one potential HLA matched unrelated bone marrow donor or UCB.
Dynamics of a two-mode two-photon Jaynes–Cummings model interacting with correlated SU(1, 1) coherent states

We study the quantum dynamics of a two-mode two-photon Jaynes–Cummings model of a two-level atom interacting with the correlated two-mode SU(1, 1) coherent states. The collapse and revival patterns in this case are noted to be quite different from those in the case of uncorrelated coherent states and correlated pair-coherent states. As an example of the time evolution of the field statistics we show that violation of the Cauchy–Schwartz inequality by the initial field states may be nullified. We also discuss the evolution of the variance of the two-mode field quadrature operator.
The comparative photobehavior of laboratory-hatched and plankton-caught Balanus improvisus (Darwin) nauplii and the effects of 24-hour starvation

Abstract Stage II nauplii of Balanus improvisus (Darwin) were obtained from laboratory-maintained adult barnacles. The immediate phototactic and photokinetic response of laboratory nauplii to light stimuli of known wavelength (460–540 nm) and quantal intensity was determined through use of closed-circuit videotape recordings quantified for computer analysis. Spectral and light intensity responses were compared with previous results using nauplii collected from the plankton. In both cases, nauplii exhibit a primary peak response to light near 480 nm and a secondary peak near 520 nm. Although the spectral response and basic patterns of photobehavior remain similar in field and laboratory nauplii, sensitivity to light intensity is significantly reduced in laboratory nauplii. Responses of fed and 24-h starved laboratory nauplii were also compared at three salinities (15, 20, 30‰). Starvation for 24 h, although inducing no major change in photopositive and photokinetic response of nauplii, can slightly depress spontaneous swimming speed and raise the threshold of intensity response for phototaxis.
Direct formation of aerogels by sol-gel polymerizations of alkoxysilanes in supercritical carbon dioxide

Implementing the Case Method of Instruction in Special Education Teacher Preparation Programs

During the last decade teacher educators' interest in the Case Method of Instruction (CMI) has revived due to pressure from within and outside of the profession. CMI uses cases, or real-life situations, to enable prospective teachers to solve problems they may encounter in the classroom. The purpose of this article is to provide guidelines for effectively implementing CMI in special education teacher preparation programs. The reader is provided with information about how to write cases, how to access (and assess) commercially-available cases, and how to present a case. Examples of inservice applications of CMI are provided, along with a discussion relating to evaluation issues.
The effect of substrate composition and storage time on urine specific gravity in dogs.

Objectives:The purpose of this study is to evaluate the effects of substrate composition and storage time on urine specific gravity in dogs. Methods:A descriptive cohort study of 15 dogs. The urine specific gravity of free catch urine samples was analysed during a 5-hour time period using three separate storage methods; a closed syringe, a diaper pad and non-absorbable cat litter. Results:The urine specific gravity increased over time in all three substrates. The syringe sample had the least change from baseline and the diaper sample had the greatest change from baseline. The urine specific gravity for the litter and diaper samples had a statistically significant increase from the 1-hour to the 5-hour time point. Clinical Significance:The urine specific gravity from canine urine stored either on a diaper or in a non-absorbable litter increased over time. Although the change was found to be statistically significant over the 5-hour study period it is unlikely to be clinically significant.
Pulsus Alternans Its Response to Amyl Nitrite Inhalation

Marked pulsus alternans was observed in a patient with primary congestive cardiomyopathy. Afterload reduction with amyl nitrite caused the disappearance of the pulsus alternans. Investigation by phonocardiography, echocardiography, systolic time interval measurement and cardiac catheterization disclosed that during pulsus alternans the weak beat originated following a short diastolic filling period and generated much lower contractile force. This report may be relevant to the currently accepted concepts of afterload reduction in the treatment of chronic congestive heart failure.
Sampling processes in emission spectroanalytical chemistry

A variety of discharge sources, including glow discharges, arcs, sparks, and magnetoplasmas, provide the ability to analyze the elemental composition of (conductive) solids without requiring dissolution or other time-consuming sample preparation. The state of development of these techniques varies from nascent to well-established, and the performance is similarly diverse. The physics and chemistry of sampling of solids with plasmas is explained. The degree to which various processes occur in each technique is discussed, and the performance of each technique is related to the fundamental processes which are dominant in each. Particular attention is paid to plasma heterogeneity and space charge phenomena, which dramatically affects sampling.
ManifestAR: an augmented reality manifesto

ManifestAR is an international artists' collective working with emergent forms of augmented reality as interventionist public art. The group sees this medium as a way of transforming public space and institutions by installing virtual objects, which respond to and overlay the configuration of located physical meaning. This paper will describe the ManifestAR vision, which is outlined in the groups manifesto.
Quantitative assessment of intramyocardial function using Cine DENSE MRI: a validation study

Non-invasive assessment of myocardial function plays a critical role in the management of heart disease. Conventional imaging modalities, such as echocardiography and cine MRI, are widely used for quantitative assessment of global cardiac function and qualitative assessment of regional cardiac function. Quantitative assessment of regional wall motion may additionally improve the accuracy of detecting wall motion abnormalities due to heart disease. Recently, fast cine displacement-encoded (DENSE) MRI was developed to produce relatively high quality strain maps within clinically acceptable breath-hold duration of 12 cardiac cycles [1]. While this pulse sequence is promising for clinical applications, it has not been validated. Therefore, the purpose of this study was to validate the relative accuracy of fast cine DENSE MRI in controls and patients with heart disease.
Stress Analysis of a Cryogenic Corrugated Pipe

One method to develop offshore gas reserves is to use a floating LNG plant (FLNG) on site and export the LNG via tankers. This alternative requires the use of a reliable LNG transfer system between the FLNG and the tanker under offshore conditions. One such system involves a flexible cryogenic hose whose main body is a pipe-in-pipe hose made of two concentric corrugated 316L stainless steel pipes (C-pipe) with flanged terminations. Thermal insulation is achieved by maintaining vacuum between the inner and outer corrugated stainless steel pipes. In addition, the hose assembly contains two outer layers of helical armor wires to sustain the axial load. Given the complexity and novelty of the transfer system, a finite element study was performed on the inner C-pipe — the critical fluid containment layer. The effects of strain hardening of corrugations due to cold forming and temperature were modeled. Finite element (FE) analyses of the C-pipe under axial, bending, and internal pressure loading were carried out to evaluate global load-deformation and local stress responses. Comparisons of full-scale tests at room and cryogenic temperatures to simulation predictions including the novel material model showed good agreement. However, fatigue life predictions for the C-pipe that were based on local stresses and sheet metal fatigue S-N curves did not agree with the full-scale fatigue test results. The results indicated that the spatial variation in strain hardening due to corrugation forming and biaxial local stresses during pipe deformation could play important roles in the fatigue response of the C-pipe.Copyright © 2011 by ASME
Cocaine receptors on dopamine transporters are related to self-administration of cocaine

Although cocaine binds to several sites in the brain, the biochemical receptor mechanism or mechanisms associated with its dependence producing properties are unknown. It is shown here that the potencies of cocaine-like drugs in self-administration studies correlate with their potencies in inhibiting [3H]mazindol binding to the dopamine transporters in the rat striatum, but not with their potencies in binding to a large number of other presynaptic and postsynaptic binding sites. Thus, the cocaine receptor related to substance abuse is proposed to be the one associated with dopamine uptake inhibition.
Precisely Serializable Snapshot Isolation (PSSI)

Many popular database management systems provide snapshot isolation (SI) for concurrency control, either in addition to or in place of full serializability based on locking. Snapshot isolation was introduced in 1995 [2], with noted anomalies that can lead to serializability violations. Full serializability was provided in 2008 [4] and improved in 2009 [5] by aborting transactions in dangerous structures, which had been shown in 2005 [9] to be precursors to potential SI anomalies. This approach resulted in a runtime environment guaranteeing a serializable form of snapshot isolation (which we call SSI [4] or ESSI [5]) for arbitrary applications. But transactions in a dangerous structure frequently do not cause true anomalies so, as the authors point out, their method is conservative: it can cause unnecessary aborts. In the current paper, we demonstrate our PSSI algorithm to detect cycles in a snapshot isolation dependency graph and abort transactions to break the cycle. This algorithm provides a much more precise criterion to perform aborts. We have implemented our algorithm in an open source production database system (MySQL/InnoDB), and our performance study shows that PSSI throughput improves on ESSI, with significantly fewer aborts.
Corruption and the costs of redistribution: Micro evidence from Indonesia

Abstract This paper examines the degree to which the corruption in developing countries may impair the ability of governments to redistribute wealth among their citizens. Specifically, I examine a large anti-poverty program in Indonesia that distributed subsidized rice to poor households. I estimate the extent of corruption in the program by comparing administrative data on the amount of rice distributed with survey data on the amount actually received by households. The central estimates suggest that, on average, at least 18% of the rice appears to have disappeared. Ethnically heterogeneous and sparsely populated areas are more likely to be missing rice. Using conservative assumptions for the marginal cost of public funds, I estimate that the welfare losses from this corruption may have been large enough to offset the potential welfare gains from the redistributive intent of the program. These findings suggest that corruption may impose substantial limitations on developing countries' redistributive efforts, and may help explain the low level of transfer programs in developing countries.
Syntrophic Growth with Direct Interspecies Electron Transfer as the Primary Mechanism for Energy Exchange

Direct interspecies electron transfer (DIET) through biological electrical connections is an alternative to interspecies H-2 transfer as a mechanism for electron exchange in syntrophic cultures. However, it has not previously been determined whether electrons received via DIET yield energy to support cell growth. In order to investigate this, co-cultures of Geobacter metallireducens, which can transfer electrons to wild-type G.sulfurreducens via DIET, were established with a citrate synthase-deficient G.sulfurreducens strain that can receive electrons for respiration through DIET only. In a medium with ethanol as the electron donor and fumarate as the electron acceptor, co-cultures with the citrate synthase-deficient G.sulfurreducens strain metabolized ethanol as fast as co-cultures with wild-type, but the acetate that G.metallireducens generated from ethanol oxidation accumulated. The lack of acetate metabolism resulted in less fumarate reduction and lower cell abundance of G.sulfurreducens. RNAseq analysis of transcript abundance was consistent with a lack of acetate metabolism in G.sulfurreducens and revealed gene expression levels for the uptake hydrogenase, formate dehydrogenase, the pilus-associated c-type cytochrome OmcS and pili consistent with electron transfer via DIET. These results suggest that electrons transferred via DIET can serve as the sole energy source to support anaerobic respiration.
The Impact of Climate Change and Variability on Heavy Precipitation, Floods, and Droughts

There is a direct influence of global warming on changes in precipitation and heavy rains. Increased heating leads to greater evaporation and thus surface drying, thereby increasing intensity and duration of drought. However, the water-holding capacity of air increases by about 7% per 1 °C warming, which leads to increased water vapor in the atmosphere, and this probably provides the biggest influence on precipitation. Storms, whether individual thunderstorms, extratropical rain or snow storms, or tropical cyclones and hurricanes, supplied by increased moisture, produce more intense precipitation events that are widely observed to be occurring, even in places where total precipitation is decreasing. In turn, this increases the risk of flooding. Patterns of where it rains also have been observed to change, with dry areas becoming drier (generally throughout the subtropics) and wet areas becoming wetter, especially in mid to high latitudes. This pattern is simulated by climate models and is projected to continue into the future. Since more precipitation occurs as rain instead of snow with warming, and snow melts earlier, there is increased runoff and risk of flooding in early spring, but increased risk of drought in deep summer, especially over continental areas.

Lattice Boltzmann modeling of pore‐scale fluid flow through idealized porous media

In order to capture the hydro-mechanical impacts on the solid skeleton imposed by the fluid flowing through porous media at the pore-scale, the flow in the pore space has to be modeled at a resolution finer than the pores, and the no-slip condition needs to be enforced at the grain–fluid interface. In this paper, the lattice Boltzmann method (LBM), a mesoscopic Navier–Stokes solver, is shown to be an appropriate pore-scale fluid flow model. The accuracy and lattice sensitivity of LBM as a fluid dynamics solver is demonstrated in the Poiseuille channel flow problem (2-D) and duct flow problem (3-D). Well-studied problems of fluid creeping through idealized 2-D and 3-D porous media (J. Fluid Mech. 1959; 5(2):317–328, J. Fluid Mech. 1982; 115:13–26, Int. J. Multiphase Flow 1982; 8(4):343–360, Phys. Fluids A 1989; 1(1):38–46, Int. J. Numer. Anal. Meth. Geomech. 1999; 23:881–904, Int. J. Numer. Anal. Meth. Geomech. 2010; DOI: 10.1002/nag.898, Int. J. Multiphase Flow 1982; 8(3):193–206) are then simulated using LBM to measure the friction coefficient for various pore throats. The simulation results agree well with the data reported in the literature. The lattice sensitivity of the frictional coefficient is also investigated. Copyright © 2010 John Wiley & Sons, Ltd.
Motion correction for augmented fluoroscopy - application to liver embolization

Hepatic embolization is a procedure designed to cut off blood supply to liver tumors, either hepatocellular carcinomas (HCC) or metastases from other parts of the body. While it often serves as a palliative treatment, it can also be indicated as a precursor to liver resection and liver transplants. The procedure itself is conducted under fluoroscopic X-ray guidance. Contrast agent is administered to opacify the vasculature and to indicate the arterial branches that feed the treatment target. These supply routes are then blocked by embolic agents, cutting off the tumor's blood supply. While methods exist to enhance fluoroscopic images and reduce the dependency on contrast agent, they are typically confounded by patient respiratory motion and are hence not effective for abdominal interventions. This paper presents an appearance based tracking algorithm that quickly and accurately compensates for the liver's bulk motion due to respiration, thereby enabling the application of fluoroscopic augmentations (i.e. image overlays) for hepatic embolization procedures. To quantify the accuracy of our algorithm, we manually identified vascular and artificial landmarks in fluoroscopy sequences acquired from three patients during free breathing. The average postmotion compensation landmark misalignment was 1.9 mm, with the maximum landmark misalignment not exceeding 5.5 mm.
Policy analysis for complex and uncertain systems through computational experiments

Most model based methodologies for engineering or policy design depend upon possession of a model that is predictively accurate. However, many systems of practical importance are now recognized as being both highly complex and composed of multiple interacting adaptive agents. For these systems, the construction of a model that accurately predicts the details of system behavior is essentially impossible, and any model for these systems is certain to be "wrong" in at least some details. If modeling and simulation is to be used to reason from what is known about such systems, we must understand how to think usefully with "wrong" models. This paper describes an approach based on exploratory modeling and adaptive strategies that can be used to make decisions about systems that are so complex their detailed behavior cannot be predicted. This approach seeks to find strategies that perform reasonably well over broad ranges of plausible futures-instead of devising strategies that are optimal for some particular best estimate model.
Experience with FiberWire for pectus bar attachment

Abstract Background Minimally invasive repair of pectus excavatum has become an established method for repair of pectus excavatum. Bar displacement or rotation remains the most common complication of this repair requiring return to the operating room. Methods Retrospective review of all patients at a single institution who underwent repair of pectus excavatum using FiberWire for bar stabilization between December 2009 and March 2013 was undertaken. Results 93 patients underwent minimally invasive pectus repair using FiberWire during the study period. The patients included 73 males and 20 females, with an average age of 14.6years (range 7–21years). Mean operative time was 102minutes (range 56–198minutes). No patients developed wound complications, two patients developed pain because of bar migration and required return to the OR, and no patients had recurrence of their pectus defect because of bar migration during the study period. Median length of follow-up was 17months (range 3–36months). Conclusion Stabilization of pectus bars using circumferential rib fixation with FiberWire at multiple points on both sides of the bar appears to be effective in preventing bar rotation and displacement, and requires minimal change to the operation as it has been previously described. Early experience shows a low rate of complications.
Extranodal Anaplastic Large Cell Lymphoma of the Eyelid

A sixty-nine-year-old male patient, without a significant prior medical history, presented with a rapidly enlarging, 2 cm non-tender nodule on the right lower eyelid. The lesion persisted in spite of an incision and drainage. Following an excision, the histology revealed a diffuse infiltrate of atypical mononuclear cells within the dermis. The cells were large, monomorphic, with irregular to convoluted nuclei, prominent nucleoli, amphophilic cytoplasm. They were very mitotically active. Immunohistochemical stains for CD45, CD3, and CD30 were strongly positive. Pancytokeratin, CD20, and ALK (Anaplastic Lymphoma Kinase fusion protein) were negative. The histopathologic diagnosis was CD30 (Ki-1) positive anaplastic large cell lymphoma. The margin was positive for involvement by lymphoma. The lesion was re-excised with no evidence of residual involvement by lymphoma. A primary cutaneous anaplastic large cell lymphoma was favored over systemic involvement based on the clinical presentation of a single eyelid nodule and ALK negativity. He was referred to a hematology-oncologist for further management. Anaplastic large cell lymphoma is a distinctive type of malignant lymphoma with a relatively favorable prognosis. It frequently involves the skin, however, to the best of our knowledge, presentation of this lymphoma type as a single lesion on the eyelid is extremely rare.
Key management for heterogeneous ad hoc wireless networks

Since its birth more than two decades ago, public key cryptography has been recognized as one of the most effective mechanisms for providing fundamental security services including authentication, digital signatures and encryption for dynamic networks. Effective management of keys, or digital certificates holding the keys, is one of the key factors for the successful wide-spread deployment of public key cryptography. The public key infrastructure (PKI ), an infrastructure for managing digital certificates, was introduced for this purpose. The most important component of PKI is the certificate authority (CA), the trusted entity in the system that vouches for the validity of digital certificates. This work describes a framework to provide efficient yet effective distributed CA service for ad hoc wireless networks. We select physically or computationally more secure nodes as MOCAs (MObile Certificate Authority) and use threshold cryptography to distribute the CA's private key among these MOCA nodes. We also provide a protocol for clients to contact MOCAs and get certification services without incurring excessive overhead.
Online Dating The Current Status—and Beyond

Finkel, Eastwick, Karney, Reis, and Sprecher (2012, this issue) have provided a remarkably comprehensive, thoughtful, scholarly, and timely monograph. It is also extremely important. As the data they cite show, online dating, particularly in developed countries, already accounts for a substantial proportion of the initiation of romantic relationships—a proportion growing at a rate suggesting it may soon account for the majority of such meetings. Thus, online dating is significant as a major social phenomenon. More crucially, the quality of our close relationships is the single biggest contributor to personal well-being and one of the largest contributors to health and longevity. Thus, understanding a phenomenon that is changing the landscape for the formation of such relationships bears on fundamental issues in human life. (As an aside, this monograph also contributes to the basic science of relationships by offering a wonderfully thorough and up-to-date review of the research literature on key factors in romantic attraction and on the predictors of relationship success.) Frankly, although my original intention was a quick read while waiting for the take off of a plane I was on, I found myself so engaged that by the time I had read it (and often reread sections while making a zillion little notes), the pilot was announcing it was time to prepare for landing. Several conclusions, all well supported, from their review stand out about online dating as it currently exists. First, it has significant benefits: increased opportunities to meet potential partners, minimally threatening contexts for initiating relationships, and the possibility of “omitting from the dating pool people who are likely to be poor relationship partners in gen
Public access to defibrillation

During the past 20 years, morbidity and mortality rates for nearly all types of cardiovascular disease have declined. Progress in these areas is in stark contrast to that for sudden cardiac death, which continues unabated at a rate of approximately 1,000 times per day in the United States, with little decline in incidence or improved outcome. Clearly, the problem of sudden cardiac death is best approached through prevention, but horizons in that area seem no more promising and in some respects less promising and substantially more costly than 2 decades ago. The means necessary for the successful resuscitation of a patient in cardiac arrest were known by the early 1960s. Externally performed cardiopulmonary resuscitation (CPR) could maintain an "oxygen plateau" and delay permanent brain damage long enough to allow external defibrillation using direct current (DC). The possibility of long-term survival was increasingly recognized, as early anecdotal experiences accumulated into published series. 1-3 Given the hindsight of 3 decades, the obstacles to be overcome before significant progress could be made in out-of-hospital resuscitation were formidable. First, cardiac arrest was perceived as an event that typically occurred in the hospital. In-hospital cardiac arrests are now recognized to represent only a small proportion of sudden deaths based in the community. Second, the CPR technique was known to only a limited number of hospital-based physicians. CPR is no longer restricted to hospitals or physicians; it is routinely taught to the lay public. Third, only line-powered, bulky, and awkward defibrillators were available. The first out-ofhospital defibrillation device weighed 110 lb. Contemporary external defibrillators are available that weigh less than 10 lb.
Zinc deficiency affects neither platelet arachidonic acid metabolism nor platelet aggregation in rats.

The effects of zinc deficiency on arachidonic acid (AA) metabolism and platelet aggregation were studied in rats. Concentrations of AA metabolites synthesized by collagen-stimulated platelets were greater in rats fed a zinc-deficient diet (ZD group) than pair-fed control rats (PF group). This difference appeared to be due to increased platelet number in the ZD group. Preincubation of platelet-rich plasma of ZD group with various concentrations of zinc sulfate, prior to the aggrega tion induced by collagen suspension, affected neither concentrations of AA metabolites nor the degree of platelet aggregation. Contrary to a report by other investigators, ADP-induced platelet aggregation was not impaired in rats fed the zinc- deficient diet for 1 week or 5 weeks as compared to the pair-fed controls. Secondary phase aggregation was not observed during ADP-induced platelet aggregation regard less of concentrations of ADP, types and concentrations of anticoagulants used, routes of blood collection or types of dietary protein in this study. These results indicated that zinc deficiency does not seem to affect arachidonic acid metabolism or platelet aggregation in rats in relatively short-term studies. J. Nutr. 114: 398-403, 1984.
Gendered Strategies for Success in the Early Nineteenth-Century Literary Marketplace: Mary Carr and the Ladies' Tea Tray

In April 1815 Mary Clarke Carr submitted an insolvency petition to the Philadelphia Court of Common Pleas. The petition described how Carr had failed to take in the subscription monies owed for her magazine, The Intellectual Regale, or Ladies' Tea Tray, "and lost thereby at least $200 ... the receipts not being sufficient for the support of herself and family. " As a consequence of her debts, Carr was forced to sell the rights to the magazine, along with "printing press types, printing apparatus, paper and all ... & every other thing &c pertaining to the said 'establishment.'" After collecting $256 from printer Thomas Smith in exchange for her property, Carr continued to struggle with her magazine for more than a year.1 This tale of economic uncertainty and business failure is not surprising given that war raged along the eastern seaboard, paper was scarce, and money hard to come by. Considering the circumstances, Carr's publication of the Tea Tray (as she referred to it) during this precarious time is remark able. Philadelphian Mary Clarke Carr edited this magazine which contained her own serialized fiction and plays as well as poetry and prose by other contributors. Financial difficulties plagued the magazine from the start and brought it to an end two years later. Though short-lived, the Tea Tray is a milestone in the history of women's publishing and authorship. Carr took advantage of developing print culture to do something no American woman
Dynamics of the radiative recombination in cylindrical nanostructures with type-II band alignment

Received 6 June 2008; revised manuscript received 4 February 2009; published 11 March 2009 The electron and hole states and confining potential for cylindrical core-shell structure with type-II band alignment are obtained from a numerical solution of the self-consistent Schrodinger-Poisson system of equations. The photoluminescence PL kinetics is theoretically analyzed, with the nanostructure size dispersion taken into account. The results are applied to the radiative recombination in the system of ZnTe/ZnSe stacked quantum dots. A good agreement with both cw and time-resolved experimental observations is found. It is shown that size distribution results in the PL decay that has essentially nonexponential behavior even at the tail of the decay where the carrier lifetime is almost the same due to slowly changing overlap of the electron and hole wave functions. Finally, a model situation applicable to colloidal core-shell nanowires is investigated and discussed. DOI: 10.1103/PhysRevB.79.115307 PACS numbers: 78.67.Lt, 73.21.Hb, 78.47.Cd
Notes from the 2000 American Society of Anesthesiologists Annual Meeting.

LAST OCTOBER, key ASPAN leaders attended the 2000 American Society of Anesthesiologists’ (ASA) Annual Meeting in San Francisco, CA. Vice President/President Elect Susan Shelander, Public Relations and Marketing Chair Susan Carter, Executive Director Kevin Dill, ASPAN member and Anesthesia Patient Safety Foundation Board member David Wharton, and Journal of PeriAnesthesia Nursing Interim Editor Denise O’Brien met for the opening ceremonies on October 15th as President Nancy Saufl was introduced to the House of Delegates and officers of the ASA. On the subsequent days, the ASPAN members staffed an ASPAN booth in the Scientific Exhibit area, visited and met with exhibitors, attended lectures and presentations, and participated in meetings of the Anesthesia Care Team and the Anesthesia Patient Safety Foundation. Each year at the ASA annual meeting, research findings are presented. Once again, we will highlight those findings of greatest interest to perianesthesia nurses. You can visit the ASA Web site at http://www.asahq.org to read more about the annual meeting, review abstracts of poster presentations, and obtain general information about the ASA.
Addressing Pricing Power in Integrated Delivery: The Limits of Antitrust

Prices are the major driver of why the United States spends so much more on health care than other countries do. The pricing power that hospitals have garnered recently has resulted from consolidated delivery systems and concentrated markets, leading to enhanced negotiating leverage. But consolidation may be the wrong frame for viewing the problem of high and highly variable prices; many "must-have" hospitals achieve their pricing power from sources other than consolidation, for example, rep- utation. Further, the frame of consolidation leads to unrealistic expectations for what antitrust's role in addressing pricing power should be, especially because in the wake of two periods of merger "manias" and "frenzies" many markets already lack effective competition. It is particularly challenging for antitrust to address extant monopolies lawfully attained. New payment and delivery models being pioneered in Medicare, especially those built around accountable care organizations (ACOs), offer an oppor- tunity to reduce pricing power, but only if they are implemented with a clear eye on the impact on prices in commercial insurance markets. This article proposes approaches that public and private payers should consider to complement the role of antitrust to assure that ACOs will actually help control costs in commercial markets as well as in Medicare and Medicaid.

Serum Protein Analysis by Electrophoresis and by the Wolfson-Cohn Chemical Method: Comparative Study

One hundred serum specimens from healthy and diseased adults were analyzed for the major protein constituents by free electrophoresis and by the Wolfson-Cohn chemical method. Albumin values obtained by the two methods were well correlated and were also in good average numerical agreement. The γ-globulin values were well correlated, but were not in quite such good numerical agreement, on a percentage basis, as were the albumin values. The α-globulin values were poorly correlated, as were also the β-globulin values. Electrophoretic examination of some of the chemical fractions indicated that part of the discrepancy between the two methods was caused by faulty chemical fractionation, particularly with respect to the globulin fractions. Determination of total solids retained by a dialysis membrane (TS) in 22 serum specimens confirmed the proportionality between TS and the electrophoretic-pattern area, and emphasized a source of error of undetermined magnitude in the calculation of electrophoretic results from simple protein totals.

Productivity and costs of utilizing small-diameter stems in a biomass-only harvest

The expanded use of woody biomass for energy has increased the number of in-woods chipping operations across the southeastern US. Young loblolly pine (Pinus taeda) stands that undergo a first commercial thinning, or sometimes a pre-commercial thinning, may serve as a potential raw material source for these chipping operations. A harvesting case study was completed using activity sampling and elemental time studies to analyze conventional logging equipment thinning and chipping of a 15-year-old planted loblolly pine stand located in the coastal plain of Virginia. All stems in the harvest were chipped for biomass and no pulpwood or sawtimber was produced. Overall individual machine productivity rates for the feller-bunchers, skidders, and chipper were 27.9, 21.2, and 75.9 green tonnes (gt) per productive machine hour, respectively. A total cut-and-haul cost of $21.28/gt was calculated using the Auburn Harvesting Analyzer (AHA). Hauling was found to comprise the largest component of total costs at 33% or $6....
A Difference Between Stem Cells from Marrow and Spleen in Initiating Splenic Megakaryocytopoiesis

SummaryBone marrow and spleen cells were transplanted from normal mice to lethally irradiated recipient mice. Comparable numbers of splenic surface colonies were formed from 105 marrow or 106 spleen cells. However, more splenic megakaryocytes were produced by stem cells from spleen than marrow. This finding indicates that there is an intrinsic difference between stem cells in the marrow and those in the spleen of normal mice.

Ionic interactions between proteins and polyelectrolytes are demonstrated as a method to trigger responsive transitions in block copolymer (BCP) photonic gels containing one neutral hydrophobic block and one cationic hydrophilic block. Poly(2-vinylpyridine) (P2VP) blocks in lamellar poly(styrene-b-2-vinylpyridine) block copolymer thin films are quaternized with primary bromides to yield swollen gels that show strong reflectivity peaks in the visible range; exposure to aqueous solutions of various proteins alters the swelling ratios of the quaternized P2VP (QP2VP) gel layers in the PS-QP2VP materials due to the ionic interactions between proteins and the polyelectrolyte. Parameters such as charge density, hydrophobicity, and cross-link density of the QP2VP gel layers as well as the charge and size of the proteins play significant roles on the photonic responses of the BCP gels. Differences in the size and pH-dependent charge of proteins provide a basis for fingerprinting proteins based on their temporal an...
A Systematic Approach in Aircraft Configuration Design Optimization

Traditional aircraft configuration design attempts to achieve improved performance and reduced operating costs by minimizing maximum takeoff weight. From the point of view of an aircraft customer, however, this method does not guarantee the optimality of an aircraft program. Multidisciplinary design optimization (MDO) is an important part of the aircraft configuration design process. This paper addresses a systematic approach in aircraft configuration design optimization. It first discusses the design parameters, constraints, objectives functions and criteria and then aircraft configuration classifications. Then the relationship between each major design option and the design requirements are evaluated. Then the systems engineering principals are presented. At the end, systems engineering approach is applied in the optimization of the aircraft configuration design and a new configuration design optimization methodology is introduced.

Analysis of the results of malaria surveillance in the migrant population in Guangxi in 2010

Objective To analyze the incidence of malaria in the migrant population in Guangxi in 2010in order to provide a basis for formulating control strategies. Methods Data on malaria surveillance in the migrant population in Guangxi in 2010were collected and statistically analyzed. Results In total,66cases of malaria were reported in Guangxi in2010.Malaria was imported in all of these cases.Blood tests were performed on 58,547migrants,62of whom tested positive for malaria and 4of whom were diagnosed clinically.Blood tests were performed on 45,435migrants with a fever,61of whom tested positive for malaria at a rate of 0.14%.People returning home to Guangxi accounted for 80.30%of all cases of malaria.Of these returnees,87.88% were returning from Africa or Southeast Asia. Conclusion The migrant population returning to Guangxi from work in Africa or Southeast Asia is the main source of malaria in Guangxi.
Early and late results of coronary artery bypass in patients with hyperlipoproteinemia

Hyperlipoproteinemia is a known risk factor for the development of coronary artery disease. To assess the perioperative and late results of myocardial revascularization for angina pectoris in patients with hyperlipoproteinemia, we reviewed the records of 200 patients (age range 24 to 75 years). Preoperatively the average New York Heart Association (N.Y.H.A.) angina class was 3.1 ± 0.7. One hundred three patients (51.5%) had type 11 disease, 95 patients (47.5%) type IV, and two (1%) had type III or V disease. The mean age of the patients with type II disease was 3 years less than that of patients with type IV disease (50 versus 53 years, p
Topical antibacterial therapy of the burn wound.

Although significant mortality still results from burn injury, a major reduction in lethal outcome due to wound sepsis has been realized. Topical antibacterial therapy should be reserved only for that group of patients in whom burn wound sepsis is a significant threat to survival or functional disability.
How Representative Are Snowball Samples? Using the Ethnosurvey to Study Guatemala-U.S. Migration

This analysis draws on binational data from an ethnosurvey conducted in Guatemala and in the United States in Providence, Rhode Island, to develop a refinement of the weighting scheme that the Mexican Migration Project uses. The alternative weighting procedure distinguishes between temporary and settled migrants by using a question on household location in the Guatemala questionnaire that is not used in the MMP. Demographic characteristics and integration experiences of the most recent U.S. trip are used to assess the composition and representativeness of the U.S. sample. Using a composite index of migrant integration to compare the impact of alternative U.S. sample weights on point estimates, I find that although the U.S. sample is broadly representative across a range of background characteristics, the MMP sample weighting procedure biases estimates of migrant integration downward.
Old Corn: New Corn

In China, the post-socialist context has been characterised by a deepening of market reforms along the lines of what is termed a 'socialist market economy'. While the new opportunities that come from the market have undermined old definitions and boundaries that formally defined the Chinese peasantry (the system of household registration, the primacy of agricultural production), the rural-urban split in this particularly Chinese form of market economy is even more stark than in the past. The term peasant (nongmin) far from becoming extinct is finding new life in the reformed economy (see also Chapter 2, by John Flower). This chapter looks at evidence of a new politics of identity emergent in China's socialist market economy.
Systematic validation of the echo particle image velocimetry technique using a patient specific carotid bifurcation model

Full field opaque flow measurement technique has significant applications in evaluating details of cardiovascular hemodyamics non-invasively. Echo Particle Image Velocimetry (Echo PIV) is a simple-to-use method that has shown promising results in our previous in vitro studies on measurements of blood flow characteristics. So far, however, no systematic validation of Echo PIV in a realistic vascular anatomy against reference-standard methods has been done. In this paper, a patient-specific carotid bifurcation model was created using biplane angiography data from an adult human male. The model reproduced vascular geometry accurately, while allowing for both Optical PIV and Echo PIV to be performed on the same flow field. A pulsatile pump and a compliance chamber were used to produce physiologically realistic flow conditions with a peak velocity around 70 cm/s, heart rate of 75 beats/min, mean Reynolds number of 1484, and a Womersley number of 16.1. The Echo PIV measurements were validated by Optical PIV technique, a gold standard for velocity field measurement, in terms of velocity, flow rate and wall shear rate profiles at a few different positions in carotid artery. Results show that the Echo PIV measurements agreed well with Optical PIV results, with a mean error 7.7% +/- 3.5% for velocity profiles, and a mean error 9.2% +/- 5.7% for wall shear rate profiles.
Design and optimization of an electrostatic energy scavenger for low power electronics

A z-direction electret based Silicon-On-Insulator (SOI) electrostatic energy harvester (EH) that uses both out-of-plane overlap and out-of-plane gap closing capacitor is designed. A mathematical model of the system is developed and solved using MATLAB ordinary differential equation solver and ten design parameters are optimized to maximize the average output power using Pattern Search algorithm of MATLAB's optimization toolbox. The device with a dimension of 6600 μm by 4225 μm by 125 μm is capable to harness a power density of 31 nW/cm3 for an input vibration source of 1g and frequency of 120 Hz operated at 0.1 atmospheric pressure. A combination of meander and fixed-fixed springs are designed to obtain required spring constant and resonance at desired frequency. Finally, the optimized system is built using CoventorWare and modal harmonic analysis is performed which depicted the primary mode to have resonance at the desired frequency.
