Long-term survival in an ovarian cancer patient with brain metastases.

Abstract Background . Central nervous system (CNS) metastases from ovarian adenocarcinoma are uncommon. The long-term prognosis for these patients is poor, with studies reporting a mean survival of less than 12 months. Case . We present a case involving a 57-year-old woman diagnosed and treated for primary ovarian cancer in 1994. She underwent optimal cytoreductive surgery and received adjuvant chemotherapy. In 1996, she was diagnosed with a right cerebellar metastatic lesion, and treated with surgery and whole-brain radiotherapy. She is currently 7 years post-treatment of her brain metatasis without evidence of recurrent disease. Conclusion . Brain metastases from primary ovarian cancer are a relatively rare finding. These patients have a poor prognosis, with studies reporting a mean survival of 12 months. However, the patient in this report remains disease-free since her treatment for metastatic disease. Aggressive surgical and radiation treatment for patients with isolated CNS metastases is reasonable.
Partially Collapsed Gibbs Samplers: Illustrations and Applications

Among the computationally intensive methods for fitting complex multilevel models, the Gibbs sampler is especially popular owing to its simplicity and power to effectively generate samples from a high-dimensional probability distribution. The Gibbs sampler, however, is often justifiably criticized for its sometimes slow convergence, especially when it is used to fit highly structured complex models. The recently proposed Partially Collapsed Gibbs (PCG) sampler offers a new strategy for improving the convergence characteristics of a Gibbs sampler. A PCG sampler achieves faster convergence by reducing the conditioning in some or all of the component draws of its parent Gibbs sampler. Although this strategy can significantly improve convergence, it must be implemented with care to be sure that the desired stationary distribution is preserved. In some cases the set of conditional distributions sampled in a PCG sampler may be functionally incompatible and permuting the order of draws can change the stationary ...
A straight-line incision for neck dissection: technical note.

n p a n s p here are several incisions that are routinely recomended to perform a neck dissection for oncologic isease. The evolution toward more conservative urgical treatment of neck disease has witnessed a ecline in the proportion of standard radical neck issections and the performance of a greater number f modified or selective neck dissections. The incision esigns to perform these operations have essentially emained unchanged over the past 3 decades, when ore radical therapy was the standard of care. The pplicability of these incisions to perform current tandard selective neck dissection must be reevaluted. As with all treatment of oncologic disease, preoprative planning is paramount to success. Any incision ust afford the surgeon the flexibility to change the ourse of the operation depending on the intraopertive findings, while allowing for optimal exposure of he operative site and to enable a rapid, safe, and ncologically sound cervical lymphadenectomy. Inciions that provide an esthetic result are also favored. ome of the traditional incisions used for neck dissecion provide excellent exposure at the expense of osmesis. An example is the variety of trifurcate inciions, which provide wide exposure to all areas of the eck but are prone to wound dehiscence and scar ontracture. We report a straight-line incision that allows the afe, rapid, and oncologically sound performance of a eck dissection, while providing improved esthetics.
Cooperative Development and Women's Participation in the Nicaraguan Agrarian Reform

The Nicaraguan agrarian reform, which began with the Sandinista victory of July 1979, is unusual in at least two, respects. First, the process of cooperative development has been the result of a large-scale mobilization of peasants and rural workers by their own mass organizations, and these rural organizations have largely shaped the course of the agrarian reform. And second, the new cooperative members benefited through the agrarian reform have included both men and women. The origins of Nicaragua's cooperative movement are found in the struggle led by the Sandinista National Liberation Front (FSLN) against the Somoza dictatorship in the late 1970s. By that time, landless rural workers, the majority without access to permanent employment, and smallholders, who also formed part of the seasonal wage labor force for agro-export production, accounted for over 75% of the rural economically active population (EAP) of 430,065 (Deere and Marchetti, p. 42). The FSLN successfully organized both groups around wage demands and working conditions on the coffee and cotton estates, and in 1978 the local committees merged to form Nicaragua's first rural union, the Rural Worker's Association (ATC). By the time of the Sandinista victory, the ATC had more than 50,000 men and women members; a year later, its membership included over one-quarter of the rural EAP.
Metal-Surface Reconstruction Induced by Adsorbate: Fe(110) p(2×2)-S

Reconstruction of the Fe(110) surface by a quarter monolayer of S is shown by lowenergy electron-diffraction intensity analysis to correspond to a model in which hardsphere atoms displace to a unique jamming point. After reconstruction the S atoms sit in fourfold hollows of touching Fe atoms with S-Fe bond lengths of 2.17 and 2.36 \AA{}. A general construction for 2\ifmmode\times\else\texttimes\fi{}2 reconstructions with rectangular symmetry is given and applied to this case and to Ni(001)(2\ifmmode\times\else\texttimes\fi{}2)-C.
Anxiety disorders in neurologic illness

Anxiety disorders frequently occur in individuals with neurologic illness. Anxiety may be a symptom of or a reaction to the neurologic disorder, a medication side effect, or a comorbid condition. The most common anxiety disorders seen in neurologic patients are panic disorder, generalized anxiety disorder, social phobia, and obsessive-compulsive disorder (OCD). Very often, these conditions go unrecognized (and therefore untreated) or are attributed to being a normal response to having a neurologic illness. However, if they are not treated, anxiety disorders can significantly increase morbidity and mortality in neurologic patients. Selective serotonin reuptake inhibitors (SSRIs) should be considered the first-line of pharmacologic treatment, because they offer a broad spectrum of efficacy in the anxiety disorders, are generally well tolerated, and are effective in treating comorbid depression. Benzodiazepines, although most effective for acute anxiety, are now considered adjunctive or second-line treatments. Cognitive behavioral therapy and other behavioral treatments are effective in the treatment of anxiety disorders. They should be considered primary treatments for patients who cannot tolerate or prefer not to take medications.
Future of Supervisory Systems in Process Industries: Lessons for Discrete Manufacturing

Abstract This paper provides a brief review of the history of process control and automated systems and an overview of what we can expect in the future, together with some lessons that may be applicable to the development and operation of highly automated discrete manufacturing systems.
Sufficient conditions for a minimum of the free-final-time optimal control problem

The sufficient conditions for a minimum of the free-final-time optimal control problem are the strengthened Legendre-Clebsch condition and the conjugate point condition. In this paper, a new approach for determining the location of the conjugate point is presented. The sweep method is used to solve the linear two-point boundary-value problem for the neighboring extremal path from a perturbed initial point to the final constraint manifold. The new approach is to solve for the final condition Lagrange multiplier perturbation and the final time perturbation simultaneously. Then, the resulting neighboring extremal control is used to write the second variation as a perfect square and obtain the conjugate point condition. Finally, two example problems are solved to illustrate the application of the sufficient conditions.

HIV antibody testing and client retention in the therapeutic community. A preliminary report of Phoenix House.

Abstract This report describes the current approach to testing for the human immunodeficiency virus (HIV) antibody at Phoenix House, a large therapeutic community (TC) in the northeastern United States, and presents findings on retention of clients who have been tested for HIV antibodies and notified of their HIV serostatus. A total of 240 clients were tested while in treatment at Phoenix House between April 1988 and July 1992. Of these, 51 tested HIV positive. An additional 76 clients had tested positive for HIV antibodies prior to entering treatment. The differences in length of treatment stay between those who tested negative while in treatment and those who tested positive while at Phoenix House was not significant ( t = 0.41, df = 238, p > .683). Although clients who tested seronegative during treatment were found to remain in treatment a significantly longer amount of time than the total population of seropositive clients ( t = 4.54, df = 314, p t = 4.08, df = 125, p
Posttransplant Erythrocytosis: An Enigma Revisited

Posttransplant erythrocytosis (PTE) is an often-recognized but poorly understood complication of renal transplantation. Defined as a persistently elevated hematocrit (>0.51), it occurs most commonly during the first 2 years posttransplant in hypertensive males with excellent allograft function. Its consequences are disputed, but may include increased risk of thromboembolic events. Traditionally, PTE has been thought to reflect excess erythropoietin production, of either native kidney or allograft origin, and to abate spontaneously with time. More recent data indicate that factors other than erythropoietin may be involved in the pathogenesis of PTE and that spontaneous resolution is relatively uncommon. Standard treatments have included serial phlebotomy and native kidney nephrectomy. It now appears that PTE also can be managed safely and effectively with converting enzyme inhibitors, a development that challenges our previous understanding of PTE and offers new avenues for investigating its pathogenesis.
New corrections for skylight estimates

Skylight, also known as diffuse solar radiation, accounts for about 16% of the total solar radiation reaching the Earth's surface; the percentage varies depending on external factors, such as the angle of the Sun with respect to the zenith and the composition of the atmosphere as well as on properties of the surface, such as albedo and tilt. Of all the factors, the composition of the atmosphere changes most frequently, primarily due to changing cloud cover and the amount and type of aerosols in the atmosphere in a given region. At present, numerical methods used to calibrate measuring devices such as shadow rings, which are bands held parallel to the sunbeam to block direct sunlight and measure the diffuse light reaching a sensor, assume an unchanging atmosphere. Such assumptions do not account for local conditions and hence can introduce large errors in skylight measurements.
Corticosteroids in treatment of obstructive lesions of chronic granulomatous disease

Two patients with chronic granulomatous disease had obstructive lesions of the gastrointestinal tract, esophagus, and genitourinary tract, which were successfully treated with corticosteroids. These obstructive lesions, caused by local granuloma formation, have been reported in 18 other patients with chronic granulomatous disease, none of whom received steroids. Our first patient, a 3-year-old boy, had emesis and weight loss associated with antral narrowing and delayed gastric emptying at age 2 years. Antibiotic therapy was ineffective, but intravenous and oral corticosteroid therapy for 10 weeks resulted in clinical cure. One year later, dysuria associated with bladder neck obstruction was also treated successfully with corticosteroids. The second child, a 10-year-old boy, had dysphagia caused by distal esophageal stenosis. Corticosteroid therapy (with concomitant antibiotics) on two occasions reversed this obstruction. Granulomatous cystitis with ureteropelvic obstruction then developed, which also responded to treatment with corticosteroids and antibiotics. Despite the risk of increased susceptibility to infection, corticosteroid therapy is justified in preventing life-threatening obstruction of vital organs.

Effects of general and selective β-adrenergic antagonists on insulin-induced cardiac and selected vascular responses in rats

Insulin administration results in vasodilation, decreased mean arterial blood pressure (MAP) and increased conductances (flow/MAP) in various vascular beds. β-adrenergic blockers antagonize this response, but the mechanism of the interplay between insulin-induced vasodilation and β-adrenergic antagonism is unknown. In this study, we evaluated the effects of β-blockade using the selective β2 antagonist ICI 118551 or the general β-antagonist propranolol on insulin-induced cardiac and regional flow responses in normal rats. Insulin-induced responses were also examined following adrenalectomy. Rats were anaesthetized and the femoral vein and artery were cannulated for infusions, sampling or monitoring of MAP and heart rate (HR). The iliac, renal, and superior mesentery arteries were equipped with pulsed-Doppler flow probes. Blood samples were collected at selected intervals. Insulin decreased blood glucose, MAP and increased conductances. Pretreatment with propranolol not only antagonized the insulin-induced decrease in MAP and increased conductance but insulin also then increased MAP and decreased conductances. ICI 11851, like propranolol, antagonized the insulin-induced decrease in MAP and increased iliac and renal artery conductances. Adrenalectomy did not alter the maximum insulin-induced effects on MAP and conductances but prevented the rebound recovery phase. β-blockade following adrenalectomy had the same effects as β-blockade alone on the insulin-induced responses. We conclude that the insulin-induced decrease in MAP and the increased flow in the selective vascular beds are modulated by a sympathetic β2-receptor-mediated pathway and this response is not due primarily to the release of adrenal catecholamine.
Elevated immunoglobulin E (IgE) levels in children with exposure to environmental lead.

Abstract Lead has been reported to be an immunosuppressive agent in animal systems at levels far below those recognized as overtly toxic. Little data exist on lead’s effects on the human immune system, especially in young children who are at greatest risk for exposure to this environmental hazard. The effects of environmental lead exposure on the human immune system were examined in a population of young children, age 9 months–6 years, from the urban population of Springfield–Greene County, Missouri. Reported here are data from 279 children with blood lead levels ranging from 1 to 45 μg/dl. White blood cell populations have been enumerated and examined for cell–surface expression of activation markers. Serum has been analyzed for IgE, specific titers to Rubella vaccine, sCD25 (the soluble form of the IL2 receptor), sCD27 (the soluble form of the lymphocyte specific member of the tumor necrosis factor receptor family), and IL4 (the cytokine interleukin 4). Variation of these assays with age of the child was considered in statistical analysis of data. A statistically significant relationship of IgE and blood lead level was found in this population; as blood lead (PbB) level increases, IgE level increases. No other statistically significant differences between risk categories or other associations with blood lead level were found. The exact mechanism for this apparent stimulus of IgE-producing B cells remains to be elucidated. The development of allergic symptoms is often preceded by an increase in IgE. These data indicate that ingested lead could play a role in this process by stimulating IgE production.
On the accuracy of least squares methods in the presence of corner singularities

Elliptic problems with corner singularities are discussed. Finite element approximations based on variational principles of the least squares type tend to display poor convergence properties in such contexts. Moreover, mesh refinement or the use of special singular elements do not appreciably improve matters. It is shown that if the least squares formulation is done in appropriately weighted space, then optimal convergence results in unweighted spaces like L(2).
Use of Heart Valves in Older Patients

It has been known for at least 2 decades that the second- and third-generation porcine and pericardial bioprosthetic valves treated with glutaraldehyde are the preferable aortic valve devices in patients ≥65 years old who require aortic valve replacement.1 Furthermore, many studies of patients in this age group, especially with coronary artery disease, have repeatedly demonstrated that these patients rarely outlive these valves.2 Bioprosthetic cardiac valves do not need warfarin anticoagulation for patients in sinus rhythm, an advantage for older patients who have many concomitant disease states or existing conditions that contraindicate warfarin anticoagulation.3 Because of recent modifications in valve fabrication, including the use of glutaraldehyde at low fixation pressures, pericardial and porcine bioprosthetic valves have become even more reliable in terms of valve integrity and are clearly the choices for aortic …
Coherent hard X-ray production by cascading stages of High Gain Harmonic Generation

Abstract We study a new approach to produce coherent hard X-rays by cascading several stages of High Gain Harmonic Generation (HGHG). Our calculation shows that such a scheme is feasible within the present technology. Compared with the Self-Amplified Spontaneous Emission (SASE) scheme for the Linac Coherent Light Source (LCLS), the HGHG scheme can provide radiation with full longitudinal coherence, narrower bandwidth, more stable central wavelength, more controllable pulse length, and much higher performance stability. The electron bunch parameters used in our calculation are those of the DESY TTF and SLAC LCLS projects. To achieve similar output power, i.e. about 15 GW , the total length of the HGHG scheme will be 88 m , while that of SASE scheme will be around 100 m .
Fast SCUC for Large-Scale Power Systems

In restructured power systems, independent system operators (ISOs) or regional transmission organizations (RTOs) execute the security-constrained unit commitment (SCUC) program to plan a secure and economical hourly generation schedule for the daily/weekly-ahead market. As the size of ISO/RTO increases, the current SCUC algorithms could face critical challenges ranging from modeling accuracy to calculation complexity. This paper introduces an efficient fast SCUC (F-SCUC) for large-scale power systems. Main components used in the proposed approach include single-hour unit commitment with network security, single-hour unit commitment adjustment, unit commitment, economic dispatch, and hourly network security check. A reasonable and operational strategy for fixing and unlocking the generating units is explored. The iterative SCUC solution is controlled efficiently to accelerate the execution. Finally, the quality of F-SCUC solution is improved by executing a quick MlP-based SCUC solution according to the F-SCUC results. A 1168-bus system with 169 thermal units, a 4672-bus system with 676 thermal units, and two large systems with 1352 and 2704 thermal units are analyzed to exhibit the effectiveness of the proposed approach.
Confessions of Belonging: My Emotional Journey as Medical Translator

Different social situations compel us to attach ourselves to different self-identities. These different selves lead to constructed images dichotomized between what we want to be (the ideal self) and how others see us (the limited self). Many different social contexts concerning my identity roles at the hospital are developed within this self-questioning, autoethnographic study of my life as a part-time medical translator. My perceptual self within those social subgroups changed—and continues to do so—as a result of hidden agendas and other manifested selves interacting with each other. The result was a negotiated identity. Thus this relived journey demonstrates the inseparable duality existing within aspects of fieldwork and self-reflexive qualitative research.
Phonotactic selectivity in two cryptic species of gray treefrogs: effects of differences in pulse rate, carrier frequency and playback level.

The two main spectral components of the advertisement calls of two species of North American gray treefrogs ( Hyla chrysoscelis and H. versicolor ) overlap broadly in frequency, and the frequency of each component matches the sensitivity of one of the two different auditory inner ear organs. The calls of the two species differ in the shape and repetition rate (pulse rate) of sound pulses within trills. Standard synthetic calls with one of these spectral peaks and the pulse rate typical of conspecific calls were tested against synthetic alternatives that had the same spectral peak but a different pulse rate. The results were generalized over a wide range of playback levels. Selectivity based on differences in pulse rate depended on which spectral peak was used in some tests, and greater pulse-rate selectivity was usually observed when the low-frequency rather than the high-frequency peak was used. This effect was more pronounced and occurred over a wider range of playback levels in H. versicolor than in H. chrysoscelis when the pulse rate of the alternative was higher than that of the standard call. In tests at high playback levels with an alternative of 15 pulses s–1, however, females of H. versicolor showed greater selectivity for the standard call when the high-frequency rather than the low-frequency spectral peak was used. This last result may reflect the different ways in which females of the two species assess trains of pulses, and the broad implications for understanding the underlying auditory mechanisms are discussed.
Modulation of the Gastrointestinal Tract of Infants by Human Milk. Interfaces and Interactions. An Evolutionary Perspective

Human milk contains agents that affect the growth, development and functions of the epithelium, immune system or nervous system of the gastrointestinal tract. Some human and animal studies indicate that human milk affects the growth of intestinal villi, the development of intestinal disaccharidases, the permeability of the gastrointestinal tract and resistance to certain inflammatory/immune-mediated diseases. Moreover, one cytokine in human milk, interleukin (IL)-10, protects infant mice genetically deficient in IL-10 against an enterocolitis that resembles necrotizing enterocolitis (NEC) in human premature infants. There are seven overlapping evolutionary strategies regarding the relationships between the functions of the mammary gland and the infant's gastrointestinal tract as follows: 1) certain immunologic agents in human milk compensate directly for developmental delays in those same agents in the recipient infant; 2) other agents in human milk do not compensate directly for developmental delays in the production of those same agents, but nevertheless protect the recipient; 3) agents in human milk enhance functions that are poorly expressed in the recipient; 4) agents in human milk change the physiologic state of the intestines from one adapted to intrauterine life to one suited to extrauterine life; 5) some agents in human milk prevent inflammation in the recipient's gastrointestinal tract; 6) survival of human milk agents in the gastrointestinal tract is enhanced because of delayed production of pancreatic proteases and gastric acid by newborn infants, antiproteases and inhibitors of gastric acid production in human milk, inherent resistance of some human milk agents to proteolysis, and protective binding of other factors in human milk; and 7) growth factors in human milk aid in establishing a commensal enteric microflora.
GATEKEEPER: mostly static enforcement of security and reliability policies for javascript code

The advent of Web 2.0 has lead to the proliferation of client-side code that is typically written in JavaScript. This code is often combined -- or mashed-up -- with other code and content from disparate, mutually untrusting parties, leading to undesirable security and reliability consequences. This paper proposes GATEKEEPER, a mostly static approach for soundly enforcing security and reliability policies for JavaScript programs. GATEKEEPER is a highly extensible system with a rich, expressive policy language, allowing the hosting site administrator to formulate their policies as succinct Datalog queries. The primary application of GATEKEEPER this paper explores is in reasoning about JavaScript widgets such as those hosted by widget portals Live.com and Google/IG. Widgets submitted to these sites can be either malicious or just buggy and poorly written, and the hosting site has the authority to reject the submission of widgets that do not meet the site's security policies. To show the practicality of our approach, we describe nine representative security and reliability policies. Statically checking these policies results in 1,341 verified warnings in 684 widgets, no false negatives, due to the soundness of our analysis, and false positives affecting only two widgets.
Direct measurements of fusion and phase transition enthalpies in lanthanum oxide

Enthalpies of high-temperature phase transitions and fusion in lanthanum oxide (La2O3) were directly measured for the first time. Three samples were prepared by laser melting, sealed in tungsten crucibles, and heated in a differential thermal analyzer calibrated by melting Al2O3. Transformation enthalpy of La2O3 from A to H phase is 23 ± 5 kJ/mol at 2046 ± 5 °C and from H to X phase is 17 ± 5 kJ/mol at 2114 ± 5 °C. Lanthanum oxide melts at 2301 ± 10 °C, with enthalpy of fusion of 78 ± 10 kJ/mol.
Runoff losses of cyanazine and metolachlor: effects of soil type and precipitation timing

Abstract The effects of time of precipitation and soil type on runoff losses of cyanazine and metolachlor were studied using a tilted-bed, microplot system. Two silt loam soils, Bosket and Dubbs, and a Sharkey silty clay were evaluated. Rainfall (22 mm h−1) was simulated at 0, 2, and 14 days after treatment (DAT). Time of precipitation did not impact herbicide losses or any of the runoff parameters evaluated in this study. Water runoff occurred sooner and in greater quantities from the surfaces of Bosket and Dubbs silt loam soils than from the surface of Sharkey silty clay. Runoff losses of cyanazine did not vary by soil type. Soil drying produced large cracks in Sharkey silty clay, which greatly reduced runoff in this soil. Combined runoff and leachate losses were highest from Dubbs silt loam. Runoff losses of metolachlor were not affected by soil type. However, regression analyses indicated that time of precipitation and soil type interacted to affect initial metolachlor concentration. At 14 DAT, initia...
Hydrodynamics of aqueous humor outflow

We present a hydrodynamic model of the aqueous outflow pathway that can, for the first time, account for the generation of outflow resistance based upon anatomical measurements. The hydraulic conductivity of the extracellular matrix in the juxtacanalicular connective tissue (JCT) is determined by combining advanced morphometric techniques with electron microscopy images taken using quick-freeze/deep-etch to preserve ultrastructural detail. A hydrodynamic interaction between pores of the endothelium of Schlemm's canal, breaks in the basement membrane, and this morphometrically-determined hydraulic conductivity lead to predictions that are consistent with experimentally-measured outflow resistances.
Cataracts induced by microwave and ionizing radiation

Abstract Microwaves most commonly cause anterior and/or posterior subcapsular lenticular opacities in experimental animals and, as shown in epidemiologic studies and case reports, in human subjects. The formation of cataracts seems to be related directly to the power of the microwave and the duration of exposure. The mechanism of cataractogenesis includes deformation of heat-labile enzymes, such as glutathione peroxide, that ordinarily protect lens cell proteins and membrane lipids from oxidative damage. Oxidation of protein sulfhydryl groups and the formation of high-molecular-weight aggregates cause local variations in the orderly structure of the lens cells. An alternative mechanisms is thermoelastic expansion through which pressure waves in the aqueous humor cause direct physical damage to the lens cells. Cataracts induced by ionizing radiation (e.g., X-rays and gamma rays) usually are observed in the posterior region of the lens, often in the form of a posterior subcapsular cataract. Increasing the dose of ionizing radiation causes increasing opacification of the lens, which appears after a decreasing latency period. Like cataract formation by microwaves, cataractogenesis induced by ionizing radiation is associated with damage to the lens cell membrane. Another possible mechanism is damage to lens cell DNA, with decreases in the production of protective enzymes and in sulfur-sulfur bond formation, and with altered protein concentrations. Until further definitive conclusions about the mechanisms of microwaves and ionizing radiation induced cataracts are reached, and alternative protective measures are found, one can only recommend mechanical shielding from these radiations to minimize the possibility of development of radiation-induced cataracts.
Leveraging online gaming for teaching student leadership and teamwork

Within the college classroom, many skills are difficult to simulate effectively. Online gaming may provide a rich environment for students to learn effective leadership and teamwork. This paper discusses the organizational difficulties of setting up such a simulation, as well as providing a preliminary conceptual framework for instructors to consider when implementing an online game simulation in their classes. The paper concludes with suggestions for encouraging students to apply the concepts they learned in the online world to their actual teams.
Recurrent severe abdominal pain in the pediatric patient.

Abstract Background Ureteropelvic junction obstruction (UPJO) is a blockage occurring at the junction of the ureter and the renal pelvis. Pediatric patients with UPJO pose a diagnostic challenge when they present to the emergency department (ED) with severe recurrent abdominal pain if there is not a level of suspicion for this condition. Objectives Our aim was to review presentation of UPJO to the ED, methods of diagnosis, and treatment of this common but often overlooked condition. Case Report We report on 2 patients, a 9-year-old and 3-year-old, who had multiple presentations to health care providers and the ED with intermittent and recurrent abdominal pain. Subsequent testing, including ultrasound (US) and computed tomography (CT) with diuretic-recreated symptoms, revealed UPJO. Open pyeloplasty was performed, resulting in complete resolution of symptoms. Conclusions UPJO is an important diagnosis to consider when patients present to the ED with recurrent abdominal pain. US can be helpful in suspecting the diagnosis, but often CT, magnetic resonance urography, or diuretic scintigraphy is required for confirmation. Diuretics can be used to aid diagnostic testing by reproducing abdominal pain at the time of imaging. Referral to a urologist for open pyeloplasty is definitive treatment for this condition.
Catalyzed decay of a false vacuum in four dimensions.

The probability of destruction of a metastable vacuum state by the field of a highly virtual particle with energy [ital E] is calculated for a (3+1)-dimensional theory in the leading WKB approximation in the thin-wall limit. It is found that the induced nucleation rate of bubbles, capable of expansion, is exponentially small at any energy. The negative exponential power in the rate reaches its maximum at the energy, corresponding to the top of the barrier in the bubble energy, where it is a finite fraction of the same power in the probability of the spontaneous decay of the false vacuum, i.e., at [ital E]=0.

Speakable and Unspeakable Passions in English Neoclassical and Romantic Poetry

“The elemental passions of the soul” were the subject of enormous interest and serious inquiry in England throughout the eighteenth century: they figured prominently not only in literature but also in such disparate cultural manifestations as medical dissertations, anatomical drawings, history paintings, political tracts, elocution lectures, acting handbooks, rhetoric textbooks, and psychological treatises. The popularity of the passions as a subject of discourse can be well documented: Edward Young, for example, plaintively confesses in the preface to a 1728 sermon, “Being sensible how difficult it is to gain Attention for Works of Divinity, I have insisted more on the Passions, than any other Head of the following discourse; in hopes of a more welcome reception”.1 Even a cursory examination of the eighteenth-century discourse on the passions reveals a remarkably heterogeneous and heterodox body of material, as diverse in opinions and evaluations of the passions as in disciplinary approach. Some, for instance, thought passion to be literally beastly; others believed that passion was what separated us from the lower animals. Passion was a hindrance to some, a useful tool for others; the enemy and master of reason or conversely its willing and manageable slave.
The Differential Roles Of Product Brand Image And Store Brand Image In Retail Loyalty: A Self-Concept Image Congruity Perspective

The effects of self-concept congruity constructs on retail loyalty have received various attentions in the marketing literature. However, to date, few studies have simultaneously investigated the differential roles of product brand image congruity and store brand image congruity in the creation of retail loyalty between different retail store types. To address this gap, two empirical models are proposed and tested to assess the differential effects of these congruity constructs under the context of two different types of retail stores (i.e., The Gap, Macy’s). Results show that, for retailers who predominately carry merely their own store-brand named products (i.e., The Gap), product brand image congruity plays a central role in the creation of retail loyalty. However, for retailers that offer a wide array of manufacturer named products (i.e., Macy’s), findings indicate that both congruity constructs, particularly store brand image congruity, serve significant roles in the creation of retail loyalty. Theoretical and managerial implications are discussed.
Inflammation and Lung Cancer: Prevention

In this chapter, the authors focus on preclinical animal modeling including the basic science connecting inflammation and lung cancer chemoprevention, preclinical testing in animal models, clinical trials, and future directions. Animal models consistently demonstrate that certain inflammatory pathways are clearly important in lung carcinogenesis. Many of these pathways, such as NRF2, PPARγ, and NFκB, are linked to multiple cancer stages (i.e., initiation, promotion, progression, and metastasis) and some (e.g., NRF2, PPARγ) are linked to both pro- and anti-inflammatory pathways depending on the stage. This emphasizes the importance of a stage-dependent approach to therapy. In addition, these early animal studies often identify systemic problems (e.g., cardiac effects of COX-2-specific inhibitors). Although no Phase III trials with lung cancer as the primary endpoint have generated the robust data that would be needed to make recommendations for chemoprevention, both low-dose aspirin and inhaled corticosteroids are of interest for further study. Iloprost has significant preclinical and Phase II data to support further investigation.
Professional prospects of graduates of the faculty of Agriculture, University of South Bohemia in České Budějovice from the years 1998-2002

A statistical survey was performed to investigate professional prospects of graduates they graduated from the Faculty of Agriculture in Ceske Budějovice in the period 1998-2002. For collecting data were used postal questionnaires. This article presents some results of this statistical research. The inquiry showed for example that the percentage of unemployed graduates of the Faculty of Agriculture is much less than the rate of unemployment in the Czech republic and almost half of the respondents had no problems with finding jobs.
Sketch Beautification in Air

Computer-based sketches are geometrically accurate and can be rendered formally. However, existing interfaces of sketching are complex, non-intuitive, and require considerable learning time for novice users. In our work, we aim to develop an intuitive gesture-based sketching interface that provide designers with the freedom of sketching in the air, without touching or wearing any physical device. With our novel sketching system, users could draw letters, symbols, and drawings using non-contact depth-sensing cameras, such as SoftKinetic and Leap Motion. The system records user’s hand trajectory as raw sketch. The sketch is analyzed and beautified to express user’s intent more accurately. Beautification process involves segmenting the sketch into different segments and rebuilding it to form a more beautified sketch. In this process, we use 2/3rd power law which provides novel kinematic features of segments and helps to improve beautification. Our results show encouraging performance for a broad range of writing styles and drawings in the air.Copyright © 2015 by ASME
The Persistence of the Confederate Narrative

Ever since the United States was reconstituted after the Civil War, a Confederate narrative of states’ rights has undermined the Reconstruction Amendments’ design for the protection of civil rights. The Confederate narrative’s diminishment of civil rights has been regularly challenged, but it stubbornly persists. Today the narrative survives in imprecise and unquestioning odes to state sovereignty. That appreciation of the doctrines of federalism and separation of powers should govern adjudication of the Constitution’s meaning is unarguable. That it should preclude national responsibility for the protection of human rights is, however, unacceptable. We analyze the relationship, over time, between assertions of civil rights and calls for the protection of local autonomy and control. This analysis reveals a troubling sequence: The Confederate narrative was shamefully intertwined with the defense of American chattel slavery. It survived profound challenges raised by post-Reconstruction civil rights claimants, and by mid-Twentieth century civil rights movements, and it reemerges regularly to pose questionable but unanswered challenges to calls for national protection of civil rights. Our close examination of the Confederate narrative’s jurisprudential effects exposes an urgent need to address the consequential but under-recognized tension between human and civil rights in the United States on the one hand and local autonomy on the other.
Sound the Alarm? Judicial Decisions Regarding Publication and Dissent:

Judges sitting on three-judge panels in the U.S. Courts of Appeals make decisions under the shadow of potential review by supervising courts, the full circuit sitting en banc and the Supreme Court. Review is more likely for published decisions, particularly when a dissent is present. Unpublished decisions do not have binding precedential status. These factors create the potential for judges to be strategic in deciding whether to publish a decision or write a dissent. We develop a formal model of decision aggregation that takes the possibility of negotiating a tradeoff between the ideological location of a rule and its precedential value into account. Implications of our model are tested empirically using an original data set of search and seizure cases. Our model and results indicate that preferences within the panel and judicial hierarchy coupled with discretionary review influence judges’ decisions regarding publication and dissent, and that these choices have important consequences.
Seasonal Incidence and Biological Control Potential of Aprostocetus hagenowii (Hymenoptera: Eulophidae) in Treehole Microhabitats

The development of Aprostocetus hagenotvii (Ratzeburg) in irradiated 2-wk-old Periplaneta americana (L.) oothecae yielded a significantly higher percentage of female-biased clutches than freeze-killed oothecae, but per clutch the number of females and males, sex ratio, and developmental time were not significantly different. Its parasitoid development studies, ootheca age and the factor clutch significantly affected the number of female and male parasitoids per clutch; younger oothecae yielded more parasitoids than older oothecae. Weekly for 30 wk, parasitoids were released in blattid-infested treeholes. Parasitism of sentinel oothecae at release sites was higher than at control sites each week after the release program was initiated. From April to November, parasitism of sentinel oothecae in control treeholes was 10-40% but peaked at 46% the week of 7 July. Weekly winter (December through March) sentinel ootheca parasitism was <10%. Parasitism of sentinel oothecae in release treeholes remained higher for 10 of the 11 wk after parasitoid releases were terminated, indicating that naturally occurring oothecae, parasitized during the release program, served as inoculum for subsequent generations of parasitoids.
Column Dynamic Study of Mass Transfer of Pure N2 and O2 into Small Particles of Pelletized LiLSX Zeolite

Effective mass transfer coefficients (κe,s–1) for adsorption of pure N2 and O2 into small particles of a pelletized sample of lithium exchanged low silica X (LiLSX) zeolite were estimated as functions of gas pressure (P) and temperature (T) by analysis of experimental column dynamic data using a specific protocol based on assumptions of a constant pattern mass transfer zone (MTZ) formation and a linear driving force model for mass transport. New column breakthrough data at different P and T for displacements of pure inert helium by pure N2 or O2 in an isobaric–isothermal adsorber were used. The mass transfer coefficients decreased linearly with increasing P and increased with increasing T. Data interpretation using a “resistances in series” model for isothermal–isobaric mass transport of an adsorbate having a linear adsorption isotherm into a pelletized zeolite particle suggested the presence of a skin resistance at the pellet surface, which in combination with resistances created by axial dispersion in t...
Openness, creativity and complexity.

In a study of personality style, relationships between dogmatism, creativity and complexity were examined for 108 undergraduates. The finding of a significant negative r (—0.25) between dogmatism and creativity corroborated theory concerning open-mindedness and creativity. Dogmatism and complexity were also correlated (—0.17).
Modeling and analysis of the stability for the power system considering the integration of the wind farms

Because of the randomicity and intermittence,the integration of large-scale wind farm brings serious influence to the stability of power system. The model of the wind power system is analyzed in this paper which includes wind turbine,shaft system and wind generator. With the User Program Interface (UPI) of PSASP and Visual C++,the user programs of load flow and transient stability calculation are built. Based on the above model,user program and actual wind farm of Fangcheng Henan province,the relation of the reactive power and the rotor speed-slip is studied. The impactive current of the wind farm penetrating into the power network is calculated. The steady-state and transient-state influence of wind farm on power system are analyzed deeply. The outcome of the simulation proves the validity and practicality of the model.
A 200C capable embedded EEPROM

Abstract An embedded logic EEPROM is presented that demonstrates full functionality at 200C. Several stress tests were performed to verify required reliability and endurance in the given temperature lifetime profile. Endurance has been demonstrated to greater than 110 thousand erase/write cycles (2000 cycles at 200C). This EEPROM is designed using a 0.18um logic process with a single 70 Angstrom gate oxide. This 0.18um process was designed to combine digital logic with high voltage (45V and 70V) BCD. A special test chip was designed containing 4 arrays of 512×39 bits. Test chips from a wafer lot that purposely skewed threshold voltage implants, poly CD, and gate oxide to achieve 6 sigma corners were probed at 200C and assembled in ceramic packages. The parts were soldered onto burn-in boards to avoid issues with sockets at high temperature. Six burn-in boards of 60 parts each were placed in a 200C oven for 1008 hours HTOL test and monitored while in a constant read mode. The paper describes the challenges...
Introduction — Two Approaches to Design

Three dimensional rapid prototyping processes (also called SFF for Solid Freeform Fabrication), such as Stereolithography (SLA) [Jacobs 92], 3D Printing [Sachs, et al. 90], and Shape Deposition Manufacturing (SDM) [Merz, et al. 94] offer two principal benefits to designers: the ability to fabricate complex structures that cannot be built with traditional techniques, and a greater degree of automation in process planning and manufacturing than traditional manufacturing processes.
Latin American Decolonial Social Studies of Scientific Knowledge: Alliances and Tensions

A distinctive form of anticolonial analysis has been emerging from Latin America (LA) in recent decades. This decolonial theory argues that important new insights about modernity, its politics, and epistemology become visible if one starts off thinking about them from the experiences of those colonized by the Spanish and Portuguese in the Americas. For the decolonial theorists, European colonialism in the Americas, on the one hand, and modernity and capitalism (and their sciences) in Europe, on the other hand, coproduced and coconstituted each other. The effects of that history persist today. Starting thought from these LA histories and current realities enables envisioning new resources for social transformations. These decolonial insights seem to receive only a passing recognition in the Latin American social studies of science and technology projects that have begun cosponsoring events and publications with northern equivalents. My focus will be primarily on the decolonial theory and on just two of its...
