The relationship between tapped delay-line and FFT processing in adaptive arrays

The use of fast Fourier transform (FFT) processing behind the elements in adaptive arrays is often considered as a means of improving the nulling bandwidth of such arrays. However, it is shown that the output signal-to-interference-plus-noise ratio obtained from an adaptive array with FFTs behind the elements is identical to that of an equivalent adaptive array with tapped delay-line processing. The equivalent tapped delay-line array has the same number of taps in each delay line as the number of time samples in the FFTs, and has a delay between taps equal to the delay between samples in the FFTs. Thus, while the bandwidth performance of an adaptive array can be improved by using time-delayed samples of each element signal, no further improvement results from taking FFTs of these sampled signals. The same bandwidth performance is obtained by simply weighting and combining the time-domain samples directly. >
A 3D subsurface imaging technique based on distributed near-ground sensors: Investigation using scale model measurements

A high resolution subsurface imaging approach based on near-ground sensor networks operating in the VHF range that utilize ultra-wideband near-field focusing was recently proposed [1]. An accurate scattering model for targets buried in realistic subsurface environment modeled as a vertically stratified medium as well as an efficient inversion technique using an UWB near-field focusing were proposed. Numerical models were used to analyze the signal penetration depth in the VHF range and validate the proposed technique for targets that are buried at various depths [2]. In this paper, in order to investigate the performance of the proposed approach under practical limitations, laboratory-based scale model measurement results are utilized. In addition, various non-uniform sensor arrangements are tested to get an insight into how to best arrange a given number of sensors to cover the largest possible area and obtain the best possible lateral resolution.
Skin Clues to a Systemic Illness

Secondary syphilis can have a wide range of clinical and histologic presentations and, therefore, may go unrecognized. We report a case of secondary syphilis with clinically nodular features. Histologic sections demonstrated an acanthotic epidermis, mixed dermal infiltrate containing plasma cells, and multiple sarcoidal-like granulomas. Treponema pallidum immunostain highlighted thin and coiled organisms in the epidermis and dermis. Laboratory studies confirmed the diagnosis with positive rapid plasma reagin and T pallidum particle agglutination assay.
Are Latinas More 'Dovish' Than Latinos? Evidence from the 2006 Latino National Survey

Public opinion research reveals that women tend to be more 'dovish' than men when it comes to certain foreign policy issues. However, much of our knowledge of the gender gap in foreign policy attitudes is based on data taken from whites and therefore it us unclear whether these results can be generalized to other populations such as Latinos. This paper extends research on the foreign policy gender gap to Latinos using data from the 2006 Latino National Survey. Specifically, we analyze Latino and Latina attitudes on a question asking whether the U.S. should keep military troops in Iraq as long as it takes to stabilize their government. The date reveals a gender gap on this policy issue, with men (both native and foreign born) being more supportive in keeping U.S. troops in Iraq than women (both native and foreign born). In addition, gender differences are larger among native born Latinos, while foreign born Latino men are more supportive than native born Latina women. The paper employs multivariate analysis to explore whether gender differences persist even after controlling for variety of predictors as well as the sources of those differences. We conclude by considering the theoretical and policy implications of our findings.
Instrument Control (iC) -- an open-source software to automate test equipment

It has become common practice to automate data acquisition from programmable instrumentation, and a range of different software solutions fulfill this task. Many routine measurements require sequential processing of certain tasks, for instance to adjust the temperature of a sample stage, take a measurement, and repeat that cycle for other temperatures. This paper introduces an open-source Java program that processes a series of text-based commands that define the measurement sequence. These commands are in an intuitive format which provides great flexibility and allows quick and easy adaptation to various measurement needs. For each of these commands, the iC-framework calls a corresponding Java method that addresses the specified instrument to perform the desired task. The functionality of iC can be extended with minimal programming effort in Java or Python, and new measurement equipment can be addressed by defining new commands in a text file without any programming.
GLOBAL LONGITUDINAL STRAIN AT PRESENTATION IS PROGNOSTIC OF SUBSEQUENT LEFT VENTRICULAR RECOVERY IN PATIENTS WITH PERIPARTUM CARDIOMYOPATHY

Peripartum cardiomyopathy (PPCM) has a variable clinical course. The aim was to test the hypothesis that global longitudinal strain (GLS) at presentation has prognostic value for left ventricular (LV) recovery and clinical outcomes. Of 100 PPCM patients in the multicenter Investigation in Pregnancy
The Detection of Rift Valley Fever Virus by a Tissue Culture Fluorescein-Labeled Antibody Method.

The diagnosis of RVF is presently confirmed by 1 or a combination of the following techniques: isolation of the virus (Findlay, 1932), serum neutralization (Brown et al, 1957), complement fixation (Brown and Findlay, 1932), hemagglutination inhibition (Mims and Mason, 1956), and the precipitation reaction in agar plates (Weiss, 1957). Iwasa (1959) has described the detection of complement-fixing antigen of RVF virus in cell cultures using the indirect fluorescent antibody technique. The present study involved the application of the direct fluorescent antibody technique (FAT) for the detection of RVF virus in 2 tissue culture cell lines and tissue sections from infected mice and lambs. The fluorescent and tissue culture techniques were combined to provide for the rapid detection and identification of the virus.
Analysis on epidemiology of varicella broken cases in Shunyi district of Beijing from 2008 to 2011

Objective The purpose of this study was to understand the epidemiological characteristics and regulation of varicella broken cases in Shunyi district of Beijing. Methods Descriptive epidemiology was used to analyze the surveillance data on varicella broken cases from 2008 to 2011 in Shunyi district of Beijing. Results A total of 1217 cases of broken varicella were reported from 2008 to 2011 in Shunyi district, taking up 31.32% of all reported cases. Varicella broken cases were mainly distributed in the urban district of Shunyi, Houshayu town and Renhe town. Age of onset was concentrated in the 4-12 age group, with a single peak in 7-year-old group. The interval between the last varicella vaccination and the incidence was proportional to the number of fever cases(χ2=21.043, P=0.000) and rash level(χ2=4.45, P=0.035). The incidence for individual with vaccination history of more than three years was 4.27 times more than the incidence for individual with less than three years' vaccination history. The symptoms of varicella broken cases vaccinated in Beijing was less severe than those vaccinated outside of Beijing(χ2=8.256, P=0.016). The rash occurrence level for vaccination of domestic vaccine was more severe than imported vaccines(χ2=15.81, P=0.003). Conclusion Varicella vaccination may be considered before students entering the first grade for varicella prevention and control. People with varicella vaccination history of more than three years should vaccinate more, and the vaccination should be expanded to those with vaccination history over three years during outbreak. The symptoms for varicella broken cases was not as severe as primary varicella. Concerns remain whether quality discrepancy exists between domestic and imported varicella vaccines.

Quality-of-Life End Points in Oncology Drug Trials

Health-related quality of life (HRQL) is a multidimensional construct that represents the patient’s perspective on valued aspects of health and functioning. Over the last several years, the pharmaceutical industry, as well as health care providers and the patient advocacy community, have shown increasing interest in HRQL as an outcome measure. Pharmaceutical companies and other sponsors of cancer clinical trials are seeking novel approaches with which to establish the benefits of treatment and to differentiate their products from other marketed products. Health care providers hope to provide cancer patients with therapies that positively affect their quality of life. To date, however, most oncology drug approvals have been based on traditional end points, such as survival and tumor response rate. This article will focus on some of the lessons learned from recent reviews of HRQL data and will describe some of the many challenges that lie ahead. ONCOLOGY 13(10):1439-1442, 1999]
The Transformation of Agrarian Society

The familiar differences between Greenwich Village in 1974 and, say, Warren, Illinois (pop. 3000), where my grandparents farmed, in 1874, are not only those between rural and urban societies, nor are they summarized by the distinction between the 20th and the 19th century or between one level and distribution of prosperity and another. Warren in 1874, more like Greenwich Village in 1774 than itself today, represents one kind of economy; Greenwich Village today and Warren today, represent another. This difference in kind is not explained by technological changes, nor by levels of prosperity, nor even by distinctive property systems, though all are relevant. Warren in 1874 was (embryonically) capitalist but still bore the trappings and in many ways behaved like earlier forms of society. Property relations, we shall see, are fundamental — but not by themselves capable of defining the difference between a settled, traditional and largely static society, and an expanding, technologically dynamic, business-oriented one.
Contextual Development: Situating the Social Change Model of Leadership Development Within a Broader Reality of Comprehensive Support

AbstractThe social change model has proven an effective and widely utilized model assisting college students in leadership development toward positive social change. However, while this particular model gives much needed attention to the process of development leading to social change, it fails to acknowledge the external factors which significantly affect the student’s capacity to develop effectively. This article discusses these issues and proposes “comprehensive support” as an additional component of the model, including two additional “C’s.” This addition attempts to more fully acknowledge the external realities affecting the potential for effective student leadership among college students.

Whetting Beginning Qualitative Researchers’ Appetites: A Review of Green and Thorogood’s Qualitative Methods for Health Research

Selecting texts for introductory qualitative research courses can be a challenge given the depth, breadth, and variety of contemporary qualitative inquiry. The new edition of Green and Thorogood’s Qualitative Methods for Health Research presents a great choice for professors teaching courses across the health care spectrum due to its authors’ ability to give students a diverse buffet designed to whet appetites and increase hunger for more qualitative research nourishment.
Expressing community through freedom market and visual connections

ABSTRACTBuilding on a long-term university/community research partnership, this article examines how different ways of conceptualizing, interpreting, and producing murals impacted how an urban community saw itself. Using a participatory action research design, university researchers worked alongside community researchers to ethnographically document the transformation. Findings indicate that the mural project constructed pathways for building relationships and community in ways that made neighborhood transformation possible. The mural project embodied this transformative goal by providing a space where people gathered with shared attention to talk and to envision how their lives and their community could be different.
Introduction of integrated risk assessment and management activities in Ventspils, Latvia

The most important aspects of integrated risk management are not the science and the tools of risk assessment, but rather the structuring of political decision–making and the initiating of a policy process based on the risk concept. Integrated risk management at the local government level was introduced in the town of Ventspils in Latvia. We first obtained the active support of the political leaders. We taught the project team to carry out all the work for themselves by giving them the appropriate education. Some of the main products were a policy plan with respect to the risks of accidents with hazardous materials and an environmental policy plan.
How should novelty be valued in science

Scientists are under increasing pressure to do "novel" research. Here I explore whether there are risks to overemphasizing novelty when deciding what constitutes good science. I review studies from the philosophy of science to help understand how important an explicit emphasis on novelty might be for scientific progress. I also review studies from the sociology of science to anticipate how emphasizing novelty might impact the structure and function of the scientific community. I conclude that placing too much value on novelty could have counterproductive effects on both the rate of progress in science and the organization of the scientific community. I finish by recommending that our current emphasis on novelty be replaced by a renewed emphasis on predictive power as a characteristic of good science.
Unintentional Cannabis Ingestion in Children: A Systematic Review.

Objective To analyze published reports of unintentional cannabis ingestions in children to determine presenting signs and symptoms, route of exposure, treatment, and outcome. Study design PubMed, OpenGrey, and Google Scholar were systematically searched. Articles were selected, reviewed, and graded using Oxford Center for Evidence-Based Medicine guidelines. Results Of 3316 articles, 44 were included (3582 children age ≤12 years). We found no high quality (Oxford Center for Evidence-Based Medicine level I or II) studies and 10 level III studies documenting lethargy as the most common presenting sign and confirming increasing incidence of unintentional ingestion in states having decriminalized medical and recreational cannabis. We identified 16 level IV case series, and 28 level V case reports with 114 children, mean age 25.2 ± 18.7 months, range 8 months to 12 years, and 50 female children (44%). The most common ingestion (n = 43, 38%) was cannabis resin, followed by cookies and joints (both n = 15, 13%). Other exposures included passive smoke, medical cannabis, candies, beverages, and hemp oil. Lethargy was the most common presenting sign (n = 81, 71%) followed by ataxia (n = 16, 14%). Tachycardia, mydriasis, and hypotonia were also commonly observed. All cases were cared for in the emergency department or admitted, and mean length of stay was 27.1 ± 27.0 hours. Twenty (18%) were admitted to the pediatric intensive care unit, and 7 (6%) were intubated. Conclusions Unintentional cannabis ingestion by children is a serious public health concern and is well-documented in numerous studies and case reports. Clinicians should consider cannabis toxicity in any child with sudden onset of lethargy or ataxia.
Lending a Hand: A Quantile Regression Analysis of Micro-Lending's Poverty Impact

This paper analyzes a database of over 18,000 women micro-finance clients of the Negros Women for Tomorrow Foundation (NWTF), a database using the Progress Out of Poverty (PPI) Scorecard as a measure of poverty. Analysis using both OLS and quantile regression models shows how observable characteristics of borrowers affect the ability of clients to reduce their measured poverty. Loan size, duration, and the economic activity supported all have strongly identifiable effects. Moreover, estimates suggest which among the poor are receiving the greatest effective help by the program. Results offer advice to the NWTF and offer insight useful to policymakers and other micro-lenders.
The Shanghai Cooperation Organization: The Security-Economics Nexus

The Shanghai Cooperation Organization (SCO), which includes China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Uzbekistan, was launched in Shanghai on June 15, 2001. SCO evolved from the “Shanghai Five,” which was created in the same Chinese city on April 26, 1996, with the same members except for Uzbekistan. The SCO also has four observer states (India, Iran, Mongolia, and Pakistan) and two dialogue partners (Belarus and Sri Lanka).

Understanding the Many-Body Basis Set Superposition Error: Beyond Boys and Bernardi

Fragment-based methods promise accurate energetics at a cost that scales linearly with the number of fragments. This promise is founded on the premise that the many-body expansion (or another similar energy decomposition) needs to only consider spatially local many-body interactions. Experience and chemical intuition suggest that typically at most four-body interactions are required for high accuracy. Bettens and co-workers [J. Chem. Theory Comput. 2014 9, 3699—3707] published a detailed study showing that for moderately sized water clusters, basis set superposition error (BSSE) undermines this premise. Ultimately, they were able to overcome BSSE by performing all computations in the supersystem basis set, but such a solution destroys the reduced computational scaling of fragment-based methods. Their findings led them to suggest that there is “trouble with the many-body expansion”. Since then, a subsequent follow-up study from Bettens and co-workers [J. Chem. Theory. Comput. 2015, 11, 5132–5143] as well a...
Immune related adverse events and their treatment in melanoma patients receiving ipilimumab.

e14598Background: Ipilimumab is an immune checkpoint inhibitor approved for the treatment of melanoma. Immune-related adverse events (irAEs) may occur as adverse effects. Most reports on irAEs are from clinical trials, which may not reflect community clinical practice and outcomes. We used a health insurance based database to identify irAEs and their treatment among patients with melanoma that received Ipilimumab, as part of regular care. Methods: We identified all melanoma patients aged 18 and older who received Ipilimumab from the Truven Health Analytics Marketscan database between 2011 and 2014. Patients had continuous insurance coverage from the period of six months prior to Ipilimumab and three months after. We further assessed the treatment for each irAEs. IrAEs were defined base on claims with one or more 228 ICD-9 codes; irAEs had to occur within a 6-month window before treatment. We used summary statistics such as means and standard deviations for continuous variables, frequencies and percentages...

Current Trends and Projected Emphasis

When Lorenz Hiltner coined the term rhizosphere in 1904 he could not have envisioned the stability of the term nor the worldwide research effort that would center upon rhizosphere ecology in relation to agriculture. Apparently, Hiltner never used the term again in any subsequent publications. Nevertheless, that single spark was sufficient to ignite the imagination of other biologists, ultimately resulting in the accumulation of a wealth of information derived from both basic and applied research.
Growth of liquid-gas interfacial perturbations driven by acoustic waves

Motivated by ultrasound-induced pulmonary hemorrhage, we computationally study acoustic waves in water interacting with a perturbed water-air interface. We demonstrate that baroclinic vorticity due to the misaligned pressure (waves) and density (interface) gradients drives the perturbation growth.
Long-term high altitude hypoxia during gestation suppresses large conductance Ca2+ -activated K+ channel function in uterine arteries: a causal role for microRNA-210.

Key points Gestational hypoxia represses ten-eleven translocation methylcytosine dioxygenase 1 (TET1) expression in uterine arteries, which is recovered by inhibiting endogenous miR-210. Inhibition of miR-210 rescues BKCa channel expression and current in uterine arteries of pregnant animals acclimatized to high altitude hypoxia in a TET-dependent manner. miR-210 blockade restores BKCa channel-mediated relaxations and attenuates pressure-dependent myogenic tone in uterine arteries of pregnant animals acclimatized to high altitude. Abstract Gestational hypoxia at high altitude has profound adverse effects on the uteroplacental circulation, and is associated with increased incidence of preeclampsia and fetal intrauterine growth restriction. Previous studies demonstrated that suppression of large-conductance Ca2+ -activated K+ (BKCa ) channel function played a critical role in the maladaptation of uteroplacental circulation caused by gestational hypoxia. Yet, the mechanisms underlying gestational hypoxia-induced BKCa channel repression remain undetermined. The present study investigated a causal role of microRNA-210 (miR-210) in hypoxia-mediated repression of BKCa channel expression and function in uterine arteries using a sheep model. The results revealed that gestational hypoxia significantly decreased ten-eleven translocation methylcytosine dioxygenase 1 (TET1) expression in uterine arteries, which was recovered by inhibiting endogenous miR-210 with miR-210 locked nucleic acid (miR-210-LNA). Of importance, miR-210-LNA restored BKCa channel β1 subunit expression in uterine arteries, which was blocked by a competitive TET inhibitor, fumarate, thus functionally linking miR-210 to the TET1-BKCa channel cascade. In addition, miR-210-LNA reversed hypoxia-mediated suppression of BKCa channel function and rescued the effect of steroid hormones in upregulating BKCa channel expression and function in uterine arteries, which were also ablated by fumarate. Collectively, the present study demonstrates a causative effect of miR-210 in the downregulation of TET1 and subsequent repression of BKCa channel expression and function, providing a novel mechanistic insight into the regulation of BKCa channel function and the molecular basis underlying the maladaptation of uterine vascular function in gestational hypoxia.
Culture and Commerce at a Postwar Publisher

The tension between commerce and culture has long been recognized as characteristic of the publishing industry. Publishers seek to put forth quality works of cultural significance yet are constrained by the need to earn a profit. This article is a case study of how this conflict played out at a postwar New York City company, Storm Publishers. Storm was a one-person operation run by Alexander Gode-von Aesch, a German immigrant best known for his work as a linguist and translator. Gode founded the company in 1947 to publish The End Is Not Yet, a pacifist novel by the German playwright Fritz von Unruh. Storm went on to publish a diverse array of scholarly and trade books until it was dissolved in 1958. The article analyzes how Gode pursued a number of strategies—relying on personal connections, developing relationships with celebrities, purchasing advertisements, soliciting reviews, cutting costs, generating subsidiary rights income, and sheer tenacity and audacity—in order to compete with larger and more established Manhattan publishers. It argues Gode harbored a contradictory attitude toward the culture–commerce dichotomy, asserting that his aim was to distribute quality works that could not make a profit while at the same time publishing books aimed at bolstering his balance sheet and lamenting others’ lack of sales. As the first history of Storm Publishers, the article sheds light on the midcentury New York publishing industry and how a small firm sought to claim a place in the postwar intellectual economy.
From Community College Attendants to Baccalaureate Recipients: A Planned Behavior Model for Transfer Students in STEM Fields of Study

Firm Maturity and the Dividend Puzzle

We examine an empirical dividend puzzle. Prior literature shows that firms that do not pay a dividend are valued by the markets more highly than dividend payers. If so, why would a value maximizing firm pay a dividend? We show that firms pay a dividend to maximize their valuation, depending on their maturity. Paying a dividend is value maximizing for mature firms. By combining valuation with the life-cycle, we can empirically indicate when a firm should pay a dividend in the life-cycle. Finally, we show that the determinants of firm value change over the life-cycle.
Functional Abdominal Pain

Recurrent abdominal pain of obscure origin is prevalent in 12–28 % of school children [2] and is one of the commonest problems encountered by physicians who care for children [3, 4]. Functional recurrent abdominal pain poses two challenges for the clinician: First is the problem of identifying the cause of a symptom that has a large differential diagnosis [5]. Second is the problem of how to be helpful to patients whose symptoms are not caused by identifiable organic disease and cannot be consistently relieved by medications, diets, or surgery.
Plantas de cobertura e manejo de aléias no plantio direto de brócolis

O plantio direto de brocolis de cabeca unica no inverno, sobre diferentes culturas de cobertura, implantadas em sistema de aleias de guandu, em rotacao com milho verde no verao, sob manejo orgânico, foi objetivo deste estudo. O delineamento foi em blocos ao acaso, em parcelas sub-divididas em faixas, com dois pre-cultivos: Sorghum bicolor e consorcio (sorgo + Crotalaria juncea ); faixas separadas pelas aleias (Cajanus cajan) . O consorcio aportou maior biomassa (64,8 t ha -1 e 21,3 t ha -1 ; 49,2 t ha -1 e 14,9 t ha -1 ) que o sorgo (51,9 t ha -1 e 18,0 t ha -1 ; 40,5 e 12,5 t ha -1 materia fresca e materia seca) nos 1o e 2o ano (2013/2014). A producao de brocolis na palha do sorgo com poda do guandu foi de 7,81 t ha -1 e 4,72 t ha -1 , e sem poda 6,55 t ha -1 e 3,17 t ha -1 ; na palha do coquetel foi maior, sendo com poda do guandu de 9,86 t ha -1 e 6,12 t ha -1 , e sem poda 8,46 t ha -1 e 4,46 t ha -1 (2013/2014). O aporte de material orgânico oriundo dos residuos das culturas anuais forneceu um total de 24,43 t ha -1 materia seca (residuos brocolis e milho verde + vegetacao espontânea) no sistema produtivo. Das aleias de guandu que nao foram podadas, colheu-se 581 kg ha -1 de feijao guandu seco e beneficiado. O emprego de adubos verdes em pre-cultivo, aliado a aleias de guandu, no plantio direto orgânico de brocolis rotacionado com milho-verde, melhora a fertilidade do solo e mantem a sustentabilidade do sistema de producao agroecologico.
Assessment of Pain in the Newborn: An Update

Preterm and term neonate pain assessment in neonatal intensive care units is vitally important because of the prevalence of procedural and postoperative pain. Of the 40 plus tools available, a few should be chosen for different populations and contexts (2 have been validated in premature infants). Preterm neonates do not display pain behaviors and physiologic indicators as reliably and specifically as full-term infants, and are vulnerable to long-term sequelae of painful experiences. Brain-oriented approaches may become available in the future; meanwhile, neonatal pain assessment tools must be taught, implemented, and their use optimized for consistent, reproducible, safe, and effective treatment.
Workshop: Engaging Cultural Differences for Global Design

Based on design case studies, it introduces strategies and techniques to create usable, meaningful, and empowering designs to engage cultural differences in a globalized world at a divisive time.
Twitter y la minificción: un espacio de contacto entre los autores y sus lectores y la creación de microrrelatos interactivos.

Twitter, the digital platform that maintains 100 million users and more than 500 million tweets per day, has created the possibility for authors and their readers to interact instantaneously. In Mexico, a country with more than 20 million Twitter users, the platform has been an ideal place for some authors to promote their microfiction and interact with their readers and followers. Mexican authors such as Guillermo Arriaga, Liliana Blum, Raquel Castro, Alberto Chimal, Francisco Hinojosa, Valeria Luiselli, Fernanda Melchor, Guadalupe Nettel, Elena Poniatowska, Cristina Rivera Garza, Alberto Ruy-Sanchez, Jordi Soler, Juan Villoro, Jorge Volpi and Jose Luis Zarate have used Twitter to publish microfiction, promote their publications and interact with their readers and followers. This article intends to analyze these authors’ use of Twitter, their publications on the platform and the connections they make with their readers and followers.
Approximation algorithms for the recovery of infrastructure after disasters under precedence constraints

Abstract We examine the problem of finding the optimal sequencing decisions that a repairing agency should follow to repair infrastructure components, subject to precedence constraints between them, after disasters. Specifically, we consider scenarios where the health of an infrastructure component continues to deteriorate unless it is being repaired, until a certain point where the component fails irreversibly. We capture precedence constraints between components (indicating that one component must be fully repaired before the other can start to be repaired) by a directed acyclic graph. We characterize approximation algorithms for sequencing decisions depending on the relationship between the rates of repair and deterioration.
Secondary building units of MOFs

Abstract This chapter introduces various metal-cluster entities, the secondary building units (SBUs), to construct metal-organic frameworks (MOFs) with robust architectures. In MOFs, metal ions and linkers sustain a defined coordination geometry within the SBUs, which leads to the formation of predictable framework structures by virtue of reticular chemistry. Knowledge about these SBUs and the resulting framework topology provides fast opportunity to synthesis of task-specific materials with desired properties. Herein, we detail different kinds of SBUs, depending on the nature of the organic functionality, and classify them according to their points of extension, the number of possible connections between them through organic linkers. This summary includes single metal nodes, metal-carboxylate clusters, metal-nitrogen SBUs, metal-organic polyhedra, and infinite rod SBUs. In this chapter, some material properties are highlighted to underline the importance of crystalline MOFs that preserve structural integrity and permanent porosity. Particular MOFs will be discussed with respect to biomedical applications.
RGS12 Is a Novel Critical NF-κB Activator in Inflammatory Arthritis.

Summary Rheumatoid arthritis (RA) is the most common inflammatory disease, which currently lacks effective treatment. Here, we discovered that the Regulator of G Protein Signaling 12 (RGS12) plays a key role in regulating inflammation. Transcriptional and protein analysis revealed that RGS12 was upregulated in human and mouse RA macrophages. Deletion of RGS12 in myeloid lineage or globally inhibits the development of collagen-induced arthritis including joint swelling and bone destruction. Mechanistically, RGS12 associates with NF-κB(p65) to activate its phosphorylation and nuclear translocation through PTB domain, and NF-κB(p65) regulates RGS12 expression in a transcriptional manner. The nuclear translocation ability of NF-κB(p65) and RGS12 can both be enhanced by cyclooxygenase-2 (COX2). Furthermore, ablation of RGS12 via RNA interference significantly blocks the inflammatory process in vivo and in vitro. These results demonstrate that RGS12 plays a critical role in the pathogenesis of inflammatory arthritis.

Evaluating cross contamination on a shared ventilator.

Background Disasters have the potential to cause critical shortages of life-saving equipment. It has been postulated that during patient surge, multiple individuals could be maintained on a single ventilator. This was supported by a previous trial that showed one ventilator could support four sheep. The goal of our study is to investigate if cross contamination of pathological agents occurs between individuals on a shared ventilator with strategically placed antimicrobial filters. Methods A multipatient ventilator circuit was assembled using four sterile, parallel standard tubing circuits attached to four 2 L anaesthesia bags, each representing a simulated patient. Each ‘patient’ was attached to a Heat and Moisture Exchange filter. An additional bacterial/viral filter was attached to each expiratory limb. ‘Patient-Lung’ number 1 was inoculated with an isolate of Serratia marcescens, and the circuit was run for 24 hours. Each ‘lung’ and three points in the expiratory limb tubing were washed with broth and cultured. All cultures were incubated for 48 hours with subcultures performed at 24 hours. Results Washed cultures of patient 2, 3 and 4 failed to demonstrate growth of S. marcescens. Cultures of the distal expiratory tubing, expiratory limb connector and expiratory limb prefilter tubing yielded no growth of S. marcescens at 24 or 48 hours. Conclusion Based on this circuit configuration, it is plausible to maintain four individuals on a single ventilator for 24 hours without fear of cross contamination.
Practical Pediatric Urology: An Evidence Based Approach—Vesicoureteral Reflux and Bladder Diverticulum

The evaluation, management, and prognosis of a child with vesicoureteral reflux (VUR) remains one of the most common, and controversial, areas of pediatric urology. With the understanding that a large majority of VUR will spontaneously resolve, the charge of the treating physician becomes how to effectively reduce the morbidity associated with VUR, while allowing time for resolution. Urinary tract infection reduction and treatment of underlying lower urinary tract dysfunction become key concepts in children with VUR. Despite our best efforts at conservative management, there is still a contingent of children who will ultimately need surgical intervention. Identifying this select group of patients before any irreversible damage to the kidneys has occurred can be one of the more challenging jobs of the pediatric urologist. In the following chapter, the authors will attempt to highlight several common themes in VUR and present the latest evidence-based approach to the management of these patients.
Image Classification in Synthetic Aperture Radar Using Reconstruction from Learned Inverse Scattering

Synthetic aperture radar (SAR) is a remote sensing technique used to obtain high-resolution images, where image classification is a primary application. However, reconstructing SAR data is difficult which makes the classification of these images even more challenging. We present a study that investigates techniques for classifying SAR images using machine learning. In particular, we compare the classification accuracy using three different training data: raw SAR observation data, reconstructions using Kirchoff migration, and reconstructions by learning an approximation to the inverse of the SAR sensing operator. We consider two different architectures, namely a multi-layer perceptron and a convolutional neural network. The training set is composed of 50,000 images from the CIFAR-10 dataset. We find that the images reconstructed using the learned approximate inverse have a higher classification accuracy than that from the SAR measurement and the Kirchoff migration approach.
Should Lungs from Hepatitis C NAT+ Donors Continue to Be Transplanted? A UNOS Registry Analysis

Purpose With the advent of a cure for HCV, HCV NAT+ donor lungs are being increasingly utilized for transplantation, but their outcomes are understudied. Our goal was to examine one-year survival of lung transplant recipients from HCV NAT+ donors. Methods We conducted retrospective review of all primary adult lung transplant recipients in the UNOS registry between January 1, 2015 and June 12, 2020. Donors were identified as being HCV NAT+ or HCV NAT-. One-year survival was examined with the Kaplan Meier method and a multivariable Cox-proportional hazards model. Results Of 11809 lung transplants performed during the study period, 222 (2%) came from HCV NAT+ donors. HCV NAT+ donors tended to be younger (33±8 vs 35±14 yrs, p=0.01) and were more likely to be white (82% vs 61%, p Conclusion Despite coming from high-risk donors, HCV NAT+ lungs have similar one-year survival and acute rejection as those coming from HCV NAT- donors. While longer-term studies are necessary, this report supports the use of NAT+ donor lungs among lung transplant candidates.
Publication misrepresentation among pediatric anesthesiology fellowship applicants: A retrospective single-center cohort study.

Background Many medical specialties have found publication misrepresentation in residency and fellowship applications, but pediatric anesthesia fellowship application data is lacking. Aims We sought to determine the prevalence of publication misrepresentation among pediatric anesthesia fellowship applications. Methods In this retrospective cohort study, fellowship applications to Stanford University's pediatric anesthesiology fellowship program from 2009 to 2019 were reviewed. Only peer-reviewed journal articles listed as accepted or published were included. Nine additional variables were collected: applicant age, gender, citizenship status, American vs. international medical school, public vs. private medical school, allopathic doctor versus osteopathic doctor, number of years between college and medical school, additional degrees, and application year. The primary outcome was the rate of publication misrepresentation, defined as peer-reviewed journal citations listed on the application that could not be verified or on which the applicant was not listed as an author. Secondary outcomes were the associations between publication misrepresentation and the additional collected variables. Results 1280 peer-reviewed journal publications from 877 applicants were reviewed. 3.4% of all citations listed as peer-reviewed journal articles were misrepresented and 9.0% of all applicants with at least 1 publication had ≥1 misrepresented publications. 30.2% of publications labelled "misrepresented" were located in our search of databases but did not have the applicant as an author, and 69.8% could not be located using the search databases. Only one of the 9 collected variables (public vs private medical school) was significantly associated with publication misrepresentation. Conclusions In this single-center retrospective study, publication misrepresentation was found to occur in one out of 11 pediatric anesthesia fellowship applications with at least one publication. Since residency and fellowship applicant publications may be heavily weighted during the application process, programs may want to include additional inquiries into the accuracy of applicant publications.
Azimuthal anisotropy relative to the participant plane from a multiphase transport model in central p + Au , d + Au , and He 3 + Au collisions at s N N = 200 GeV

Recent data from $p+p$ and $p+\mathrm{Pb}$ collisions at the Large Hadron Collider (LHC), and $d+\mathrm{Au}$ and $^{3}\mathrm{He}+\mathrm{Au}$ collisions at the Relativistic Heavy Ion Collider (RHIC) reveal patterns that---when observed in the collision of heavy nuclei---are commonly interpreted as indicators of a locally equilibrated system in collective motion. The comparison of these data sets, including the forthcoming results from $p+\mathrm{Au}$ and $p+\mathrm{Al}$ collisions at RHIC, will help to elucidate the geometric dependence of such patterns. It has recently been shown that a multiphase transport model (AMPT) can describe some of these features in LHC data with a parton-parton scattering cross section comparable to that required to describe $A+A$ data. In this paper, we extend these studies by incorporating a full wave-function description of the $^{3}\mathrm{He}$ nucleus to calculate elliptical and triangular anisotropy moments ${v}_{2}$ and ${v}_{3}$ for $p+\mathrm{Au}$, $d+\mathrm{Au}$, and $^{3}\mathrm{He}+\mathrm{Au}$ collisions at the RHIC top energy of 200 GeV. We find reasonable agreement with the measured ${v}_{2}$ in $d+\mathrm{Au}$ and $^{3}\mathrm{He}+\mathrm{Au}$ and ${v}_{3}$ in $^{3}\mathrm{He}+\mathrm{Au}$ for transverse momentum $({p}_{T})\phantom{\rule{4.pt}{0ex}}\ensuremath{\lesssim}1\phantom{\rule{4.pt}{0ex}}\mathrm{GeV}/c$, but underestimate these measurements for higher values of ${p}_{T}$. We predict a pattern of coefficients $({v}_{2},{v}_{3})$ for $p+\mathrm{Au}$, dominated by differences in the number of induced local hot spots (i.e., one, two, or three) arising from intrinsic geometry. Additionally, we examine how this substantial azimuthal anisotropy accrues during each individual evolutionary phase of the collision in the AMPT model. The possibility of a simultaneous description of RHIC- and LHC-energy data, the suite of different geometries, and high multiplicity $p+p$ data is an exciting possibility for understanding the underlying physics in these systems.
Metabolic Control Mechanisms in Insects

Publisher Summary The rates of enzyme-catalyzed reactions in insects are controlled by the concentration of substrates, ions, and other co-factors, as well as by enzyme concentrations. For example, the rate of oxidative phosphorylation offlying insects presumably depends on the concentration of phosphate acceptor as deduced from studies on mitochondria isolated from flight muscle. Enzyme concentrations are presumably controlled by repression of genetic material inmicro-organisms. Less understood is the control of enzyme levels in insect tissues. Chromosomal RNA synthesis in the large polytene chromosomes of flies may be controlled by hormones, by undetermined mechanisms involving other small molecules or ions, or by other mechanisms perhaps involving proteins. Finally, the compartmentation of ions and molecules within the hemolymph, within cells, and within intracellular compartments such as mitochrondria, is controlled by limiting membranes. This chapter describes experiments and theoretical concepts relating to each level of control mentioned in the chapter.
Practical limits on software dependability: a case study

The technology for building dependable computing systems has advanced dramatically. Nevertheless, there is still no complete solution to building software for critical systems in which every aspect of software dependability can be demonstrated with high confidence. In this paper, we present the results of a case study exploration of the practical limitations on software dependability. We analyze a software assurance argument for weaknesses and extrapolate a set of limitations including dependence upon correct requirements, dependence upon reliable human-to-human communication, dependence upon human compliance with protocols, dependence upon unqualified tools, the difficulty of verifying low-level code, and the limitations of testing. We discuss each limitation’s impact on our specimen system and potential mitigations.
The Day the Solar Wind Almost Disappeared

On 11 May 1999, the flux of the solar wind, which carries charged particles away from the sun, decreased to very low values for an unusually long time. In this Perspective, [Lazarus][1] recounts the discussions of this event at a recent meeting. The reasons for low-density solar wind periods are not known, but detailed observations of its interactions with Earth's magnetic field were obtained. The event also provided an opportunity to obtain fundamental insights into the solar corona where the solar wind originates. [1]: http://www.sciencemag.org/cgi/content/full/287/5461/2172
Purification and structural characterization of transcriptional regulator Leu3 of yeast.

The transcriptional regulatory protein Leu3 of Saccharomyces cerevisiae was enriched approximately 70-fold above wild type level in yeast cells carrying a pGAL1-LEU3 expression vector. Sustained overproduction of Leu3 following induction by galactose required elevated intracellular levels of alpha-isopropylmalate, a leucine pathway intermediate known to act as transcriptional co-activator. Starting with galactose-induced cells, the Leu3 protein was purified about 3,500-fold (i.e. 245,000-fold over wild type level) by a procedure that included treatment of the cell-free extract with polyethylenimine, fractionation with ammonium sulfate, heat treatment, and DNA affinity chromatography. Highly purified preparations still showed two protein bands when subjected to polyacrylamide electrophoresis under denaturing conditions. Their apparent molecular masses were about 104,000 and 110,000 kDa. The smaller of these values was very close to the maximum molecular weight obtained previously for Leu3 protein translated in vitro in a rabbit reticulocyte lysate. (The molecular weight deduced from the open reading frame of the LEU3 gene is 100,162.) Both protein bands reacted with antibodies raised against different portions of the Leu3 molecule and were, therefore, likely to represent two forms of Leu3. Treatment with calf intestinal phosphatase quantitatively converted the slower moving band into the faster moving one. Conversion was prevented by inorganic phosphate, a phosphatase inhibitor. These experiments showed that the two bands very likely correspond to phosphorylated and nonphosphorylated forms of Leu3. Phosphorylation did not appear to affect the DNA binding function of Leu3, but (indirect) effects on the activation function or effects on the modulation by alpha-isopropylmalate have not been ruled out. Electrophoretic mobility shift assays were used to estimate the apparent dissociation constants of the two specific Leu3-DNA complexes routinely seen in these assays. The values obtained were 1.1 and 2.6 nM. Finally, using size exclusion chromatography, native Leu3 protein was shown to have dimeric structure, irrespective of the state of phosphorylation.
