Massive pellet and rupture disk testing for disruption mitigation applications

Injection of massive quantities of noble gases or D 2 has proven to be effective at mitigating some of the deleterious effects of disruptions in tokamaks. Two alternative methods that might offer some advantages over the present technique for massive gas injection are “shattering” massive pellets and employing close-coupled rupture disks. Laboratory testing has been carried out to evaluate their feasibility. For the study of massive pellets, a pipe gun pellet injector cooled with a cryogenic refrigerator was fitted with a relatively large barrel (16.5 mm bore), and D 2 and Ne pellets were made and were accelerated to speeds of ∼600 and 300 m/s, respectively. Based on the successful proof-of-principle testing with the injector and a special double-impact target to shatter pellets, a similar system has been prepared and installed on DIII-D and should be ready for experiments later this year. To study the applicability of rupture disks for disruption mitigation, a simple test apparatus was assembled in the lab. Commercially available rupture disks of 1 in. nominal diameter were tested at conditions relevant for the application on tokamaks, including tests with Ar and He gases and rupture pressures of ∼54 bar. Some technical and practical issues of implementing this technique on a tokamak are discussed.
Teaching Cre to follow directions.

Tyrosine recombinases carry out a variety of important functions involved in moving and maintaining genomes (1). Several members of this family, including the bacteriophage P1 Cre recombinase and the bacteriophage λ-integrase, have also emerged as powerful tools with broad applications in genetic engineering and molecular biology (2, 3). Although structural, biochemical, and genetic experiments have revealed in some detail how the tyrosine recombinases carry out the recombination process, it is less clear how the more complex members of this family achieve a high level of regulation or how the tightly regulated recombinases have evolved such complexity. An article in a recent issue of PNAS (4) provides important new insights into both questions. By making a chimeric protein composed of Cre recombinase fused to a small DNA-binding domain of λ-integrase, Warren et al. (4) have turned the normally unregulated Cre into a regulated integrase with the same requirements and directionality found in the λ-integrase system.
Acute Heat Stress and Reduced Nutrient Intake Alter Intestinal Proteomic Profile and Gene Expression in Pigs

Heat stress and reduced feed intake negatively affect intestinal integrity and barrier function. Our objective was to compare ileum protein profiles of pigs subjected to 12 hours of HS, thermal neutral ad libitum feed intake, or pair-fed to heat stress feed intake under thermal neutral conditions (pair-fed thermal neutral). 2D-Differential In Gel Electrophoresis and gene expression were performed. Relative abundance of 281 and 138 spots differed due to heat stress, compared to thermal neutral and pair-fed thermal neutral pigs, respectively. However, only 20 proteins were different due to feed intake (thermal neutral versus pair-fed thermal neutral). Heat stress increased mRNA expression of heat shock proteins and protein abundance of heat shock proteins 27, 70, 90-α and β were also increased. Heat stress reduced ileum abundance of several metabolic enzymes, many of which are involved in the glycolytic or TCA pathways, indicating a change in metabolic priorities. Stress response enzymes peroxiredoxin-1 and peptidyl-prolyl cis-trans isomerase A were decreased in pair-fed thermal neutral and thermal neutral pigs compared to heat stress. Heat stress increased mRNA abundance markers of ileum hypoxia. Altogether, these data show that heat stress directly alters intestinal protein and mRNA profiles largely independent of reduced feed intake. These changes may be related to the reduced intestinal integrity associated with heat stress.
Meridional Circulation Cells and the Source Waters of the Pacific Equatorial Undercurrent

Abstract A 3½-layer model is used to study the meridional circulation cells that provide the source waters of the Pacific Equatorial Undercurrent (EUC). Its three active layers represent tropical, thermocline, and upper-intermediate waters, respectively, and across-interface flow between the layers parameterizes the processes of upwelling, subduction, and diapycnal mixing. Solutions are driven by climatological winds in a domain resembling the Pacific basin from 35°S to 55°N. An additional forcing mechanism is a specified inflow into layer 3 across the open southern boundary and a compensating outflow from layers 1 and 2 along the western boundary just north of the equator; the resulting circulation simulates the Pacific interocean circulation (IOC), in which intermediate water enters the South Pacific and the same amount of thermocline and tropical waters exit via the Indonesian Throughflow. Five meridional cells contribute to the EUC in the main-run solution: north and south Subtropical Cells (STCs), no...
Job Access in Disadvantaged Neighborhoods in Cleveland, 1980-2000: Implications for Spatial Mismatch and Association with Crime Patterns

Various social ills in disadvantaged neighborhoods may be attributed to lack of job access. This study uses two distinctive measures to examine the issue: the job proximity index measures the physical distances between residence and job, and the job accessibility index measures residents' ability to reach jobs that also may be affected by availability of transportation means and job competition intensity. This research in Cleveland, Ohio, indicates that disadvantaged neighborhoods actually enjoyed better job proximity or at least that residents were located no farther away from jobs than others. These neighborhoods suffered from poorer job accessibility, however, because of their relatively lower levels of automobile ownership and the more intensive job competition in these high-density residential areas. Job accessibility alone was negatively associated with crime rates in Cleveland throughout the study period (1980-2000). When socioeconomic covariates were controlled for, the relationship remained significant in 1980, became weaker in 1990, and was not statistically significant in 2000.
Photostability of thymine and its water complexes

The photophysical and photochemical properties of electronically excited states of thymine and its water complexes are studied using resonantly enhanced multiphoton ionization spectroscopy. After initial excitation by a nanosecond laser, the excited thymine molecule is trapped in a dark state with a lifetime of tens of nanoseconds. Ionization from this dark state by deep ultraviolet (UV) radiation has a substantially high yield. The lifetime of the dark state is rapidly decreased by adding water molecules. These results indicate that the photostability of our genetic code is not an intrinsic property of the bases themselves. Quenching by solvent water molecules may be the key for the photostability of the DNA bases.
Approximate Methods for Obtaining Multi‐Phase Modes in Nonlinear Dispersive Wave Problems

Perturbation and numerical methods are used to find singly periodic and multiply periodic solutions to equations which arise in the study of nonlinear wave propagation. Approximation techniques such as these are essential in those cases where exact representations of the modes are not feasible.
Intervalence Charge Transfer Mediated by Silicon Nanoparticles

Stable silicon nanoparticles (SiNPs) were synthesized by using a wet chemical method with (3-aminopropyl)triethoxysilane as the silicon source and ethynylferrocene as the capping ligands by taking advantage of the unique chemical reactivity of acetylene moieties with silicon hydride on the nanoparticle surface, forming Si−CH=CH− interfacial bonds under UV photoirradiation. Transmission electron microscopic measurements showed good dispersion of the nanoparticles with an average core diameter of 2.96±0.46 nm. From UV/Vis absorption measurements, the nanoparticle bandgap was estimated to be 2.6 eV. XPS measurements confirmed the successful attachment of ethynylferrocene ligands onto the nanoparticle surface, with a footprint consistent with that of ferrocene. Electrochemically, the nanoparticles exhibited only one pair of voltammetric waves in the dark, suggesting a lack of effective electronic communication between the particle-bound ferrocenyl moieties, because of the low conductivity of the nanoparticle cores; whereas, under UV photoirradiation (365 nm), two pairs of voltammetric peaks were observed, with a potential spacing of 125 mV, suggesting that the nanoparticles behaved analogously to a Class II compound. This was ascribed to photo-enhanced electronic conductivity of the nanoparticle cores that facilitated intervalence charge transfer of the particle-bound ferrocene moieties.
Effect of Cooling Rate on the Structure of Rapidly Cooled Fe75Si15 B10

Solidification of metal alloys by rapid quenching can result in the formation of amorphous or microcrystalline solids, or materials with improved microstructural homogeneity, all with the view of forming new phases or obtaining improved properties. Some alloys may be cooled at high rates to achieve “microcrystallinity” but cannot be cooled rapidly enough to become amorphous. Other alloys may achieve both conditions depending on the cooling rate. We have examined the effects of cooling rate on the structure of one alloy that can, depending on the cooling rate, be made partially or completely amorphous. The alloy is Fe75Si15B10 (atom percent) which was formed as ribbon by melt spinning and as powder by spark erosion in dielectrics of different cooling characteristics and by gas-water atomization. The structural characteristics were determined by x-ray diffraction, measurements of magnetic properties and by optical and scanning electron microscopy.
Seams of Conical Intersections Relevant to the Quenching of OH(A2Σ+) by Collisions with H2

Using multireference configuration interaction wave functions composed of 17–52 million configuration state functions, 18 points on the 12A–22A seam and 162 points on the 22A–32A seam of conical intersections relevant to the collisional quenching of OH(A2Σ+) by H2 are determined and analyzed. In the vicinity of planar nuclear configurations, the former seam corresponds to a 12A′–12A″ seam of intersection and the latter corresponds to a 12A′–22A′ seam. For the previously studied 22A–32A seam, two regions not previously examined are reported: (i) an out-of-plane region that connects smoothly to the 12A′–22A′ seam for planar structures and (ii) a Rydberg region that includes D3h/C3v structures where the 22A–32A seam is a 22A′–32A′ seam for D3h structures. Some of the nonplanar points on the 22A–32A seam of conical intersection are found to have OH and H2 distances comparable to those of the reactant molecules and energies below that of the reactant asymptote. These nonplanar entrance channel conical intersec...
GLOBAL OPTIMIZATION OF DYNAMIC SITE LAYOUT PLANNING IN CONSTRUCTION PROJECTS

Dynamic site layout planning in construction projects focuses on identifying the location and space of temporary construction facilities on sites while considering the dynamic changes in the needs and availability of site space over the project duration. Existing dynamic site layout planning models generate layout plans of construction stages chronologically without considering their future effects which may lead to non-optimal or infeasible solutions. This paper presents the development of an Approximate Dynamic Programming (ADP) model that is capable of globally optimizing dynamic site layout plans of construction projects in order to minimize overall site layout costs. The developed model is equipped with the look-ahead capabilities of ADP to consider the future effects of site layout decisions in early stages on layout quality and feasibility in future stages. An application example is analyzed to illustrate the use and capabilities of the developed model in generating global optimal solution for dynamic site layout planning of construction projects.
On the impact of communication delays on power system automatic generation control performance

In this paper, we investigate the impact of communication delays on the performance of power system automatic generation control (AGC). To this end, we formulate a hybrid system model that describes the power system electromechanical behavior, including the AGC system dynamics. Through linearization and discretization, this hybrid system model is converted into a discrete-time linear time-invariant system model that includes the effect of delays in the AGC system communication channels. The stability of the closed-loop system can then be determined by examining the characteristics of the state-transition matrix of the aforementioned discrete-time linear system. Interesting findings include that increasing communication delay may help decrease the largest eigenvalue magnitude of the state-transition matrix. However, in reality, the delay is not constant or deterministic. We carefully analyze the stability of systems with random communication delays and nonzero mean random disturbances. The proposed analysis methodology is illustrated and verified through numerical examples.
Quantum Interfaces Based on Nanophotonic Systems

We will discuss recent developments at a new scientific interface between quantum optics and nano science involving realization of hybrid systems combining quantum emitters and nanophotonic devices. We will discuss how these techniques are used for realization of quantum nonlinear optics and quantum networks.
New Conceptions of Liberty

Liberty had a single central meaning for most of its history: government by law to serve the common good. Libertas meant life without subjection, except to public reason, expressed through elections. This last provision protects the rest and represents the point where republicanism and liberalism first explicitly diverged in the early nineteenth century. Even before this separation, partisans of monarchy frequently emerged to challenge liberty and question its republican antecedents. Thomas Hobbes, one of the subtlest and most lucid of such theorists, made a profound impression on subsequent debate, to the extent that republican liberty lost its meaning for many, and often even self-styled “liberals” and “republicans” now use Hobbesian terminology.
Defining antigen-specific plasmablast and memory B cell subsets in human blood after viral infection or vaccination

Antigen-specific B cells bifurcate into antibody-secreting cells (ASCs) and memory B cells (MBCs) after infection or vaccination. ASCs (plasmablasts) have been extensively studied in humans, but less is known about B cells that become activated but do not differentiate into plasmablasts. Here we have defined the phenotype and transcriptional program of a subset of antigen-specific B cells, which we have called 'activated B cells' (ABCs), that were distinct from ASCs and were committed to the MBC lineage. We detected ABCs in humans after infection with Ebola virus or influenza virus and also after vaccination. By simultaneously analyzing antigen-specific ASCs and ABCs in human blood after vaccination against influenza virus, we investigated the clonal overlap and extent of somatic hypermutation (SHM) in the ASC (effector) and ABC (memory) lineages. Longitudinal tracking of vaccination-induced hemagglutinin (HA)-specific clones revealed no overall increase in SHM over time, which suggested that repeated annual immunization might have limitations in enhancing the quality of influenza-virus-specific antibody.
An effective DNA vaccine platform for Middle East respiratory syndrome coronavirus

Middle East respiratory syndrome coronavirus (MERS-CoV) is an ongoing emerging infectious disease across the Arabian Peninsula, with the majority of cases occurring in Saudi Arabia. Through September 23, 2016 the World Health Organization reported about 1,806 total cases, including 643 deaths from 27 countries (http://www.who.int/emergencies/mers-cov/en/). The disease is comprised of a lower respiratory infection wherein individuals exhibit pneumonia-like symptoms that often lead to multi-organ failure and death (1). In addition to close contact with infected camels, transmission from human-to-human most commonly occurs in the hospital setting through close contact between patients and hospital workers (1). MERS-CoV has also been isolated from objects within patient rooms including bed sheets, bed rails, and IV fluid hangers (2), which may all be potential sources of transmission. Several cases of MERS-CoV have been associated with travelers returning home from the Middle East and developing symptoms, including two cases of health care workers returning to the United States (3). The potential for global spread was recently illustrated by a South Korean national returning home from visiting the Arabian Peninsula in May, 2015, and initiating an outbreak that infected 186 people resulting in 20% mortality and a nationwide economic crisis (4). Nonetheless, MERS-CoV is not thought to be sustained in the human population through human-to-human transmission, but may instead be continuously re-introduced into the human population from a zoonotic source, most likely dromedary camels because of high seropositive rates in herds throughout the Middle East (5,6). As camels are integral to the Saudi Arabian culture and economy, nationwide culling of camel herds is not feasible. Consequently, camel vaccination is being considered (7); however, therapeutic strategies have primarily focused on interfering with MERS-CoV infection in humans (3,5).

Endocytic Trafficking at the Mature Podocyte Slit Diaphragm.

Endocytic trafficking couples cell signaling with the cytoskeletal dynamics by organizing a cross-talk between protein networks in different subcellular compartments. Proteins residing in the plasma membrane are internalized and transported as cargo in endocytic vesicles (i.e. endocytosis). Subsequently, cargo proteins can be delivered to lysosomes for degradation or recycled back to the plasma membrane. The slit diaphragm is a modified tight junction connecting foot processes of the glomerular epithelial cells podocytes. Signaling at the slit diaphragm plays a critical role in the kidney while its dysfunction leads to glomerular protein loss (proteinuria) manifesting as nephrotic syndrome, a rare condition with an estimated incidence of 2-4 new cases per 100,000 each year. Relatively little is known about the role of endocytic trafficking in podocyte signaling and maintenance of the slit diaphragm integrity. This review will focus on the role of endocytic trafficking at the mature podocyte slit diaphragm.
Slogans in Higher Education: A Longitudinal Study (An Abstract)

This study investigates and analyzes university/college slogans which play an important role regarding institution-specific positioning and digital marketing. By discussing the literature and morphological issues (word formation in sentences), the study investigates 1935 universities and 4-year colleges in the USA. Findings of this study reveal that nearly half of the institutions used slogans in 2007 on their Websites. At the same time, this number declined significantly after 7 years in 2014. These findings clearly support the notion that universities and colleges are showing limited interest regarding placing slogans on their Websites. Interest in slogans may be declining because of the appearance of new technology platforms and digital media. Findings of the study confirm that slogans help universities and colleges to seek identity and develop online marketing campaigns that aim at differentiating their academic programs and institutional image. The paper carries a meaningful value added in the areas of positioning and digital marketing which often change in higher education to deal with competition, digital technologies, and new delivery methods.
Why Unexpectedly Positive Experiences Make Decision Makers More Optimistic: An Explanation

Experiments show that unexpectedly positive experiences make decision makers more optimistic. However, there seems to be no convincing explanation for this experimental fact. In this paper, we show that this experimental phenomenon can be naturally explained within the traditional utility-based decision theory.
Are Nonhomogeneous Poisson Process Models Preferable to General-Order Statistics Models for Software Reliability Estimation?

As alternatives to general order statistics (GOS) models, several nonhomogeneous Poisson process (NHPP) models have been proposed in the literature for software reliability estimation. It has been known that an NHPP model in which the expected number of events (μ) over (0, ∞) is finite (called an NHPP-I process) is a Poisson mixture of GOS processes. We find that the underlying GOS model better fits the data in the sense that it has a larger likelihood than the NHPP-I model. Also, among unbiased estimators for an NHPP-I model, if an estimator is optimal for estimating a related feature of the underlying GOS model, then it is also optimal for the NHPP-I estimation problem. We conducted a simulation study to compare maximum likelihood estimators for one NHPP-I model and for its corresponding GOS model. The results show for small μ and small debugging time the estimators for NHPP-I model are unreliable. For longer debugging time the estimators for the two models behave similarly. These results and certain logical issues suggest that compared to an NHPP-I model, its underlying GOS model may better serve for analyzing software failure data.
Beyond many-body localized states in a spin-disordered Hubbard model

A prime characterization of many-body localized (MBL) systems is the entanglement of their eigenstates; in contrast to the typical ergodic phase whose eigenstates are volume law, MBL eigenstates obey an area law. In this paper, we show that a spin-disordered Hubbard model has both a large number of area-law eigenstates as well as a large number of eigenstates whose entanglement scales logarithmically with system size (log-law). This model provides a microscopic Hamiltonian which is neither ergodic nor MBL. We establish these results through a combination of analytic arguments based on the eta-pairing operators combined with a numerical analysis of eigenstates. In addition, we describe and simulate a dynamic time evolution approach starting from product states through which one can separately probe the area-law and log-law eigenstates in this system.
Disease and injury: Beyond current thinking about top causes of cattle morbidity

Abstract This chapter focuses on the welfare implications of dystocia, diarrhea, mastitis, lameness, and respiratory disease, which are among the most common conditions in beef and dairy cattle. The magnitude of the associated welfare concerns may be elucidated by evaluating the prevalence, severity, and duration on a disease-by-disease basis. As reviewed here, recent trends in cattle morbidity and mortality rates, and considering the short- and long-term negative consequences that ill-health may have on a range of outcomes, from basic functioning to affective states, indicate that disease remains a major risk factor for poor welfare. In turn, mitigation may occur at three junctures—prevention, diagnosis, and treatment—with different barriers and opportunities at each stage. Overall, demands placed on cattle in modern production systems have the potential to at once increase the likelihood of disease, but simultaneously, offer opportunities to manage proactively in order to optimize health and welfare.

Cognitive performance and symptoms of anxiety, depression, and apathy in Parkinson’s patients with and without mild cognitive Impairment. (P1.043)

Objective: The purpose of this study was to examine the cross-sectional association between mood symptoms and cognitive performance in Parkinson’s patients with MCI (PD-MCI) and Parkinson’s patients who were cognitively normal (PD-Normal Cognition; PD-NC). Background: Mild cognitive impairment (MCI) and mood symptoms, specifically anxiety, depression, and apathy, are common in patients with Parkinson’s disease (PD). It is unclear if the magnitude of the association between cognitive performance and mood symptoms differs by MCI status in PD. Lastly, despite the fact that various mood symptoms (depression, anxiety, and apathy) are commonly comorbid, the relative importance of each individual mood symptom on cognitive performance is understudied in that much of the prior work has only investigated these important mood symptoms in isolation and not simultaneously. Design/Methods: In this cross-sectional study, PD participants (N=156) completed a comprehensive neuropsychological assessment that included measures of attention, working memory, language, memory, executive functioning, and symptoms of anxiety, depression, and apathy. Participants were classified into PD-MCI (N = 58) or PD-NC (N=98) using standard criteria. Linear regression analyses were conducted to examine the association between mood symptoms and cognitive performance and the relative importance of PD-MCI status. Results: Greater symptoms of anxiety, depression, and apathy were associated with worse executive function, specifically set-switching ability, which was independent of PD-MCI status. Additional analyses, however, indicated that the magnitude of the association between anxiety and worse set-switching was greater for participants with PD-MCI than PD-NC, and had the most robust association with set-switching. Conclusions: Symptoms of anxiety, depression, and apathy were most associated with set-switching ability regardless of MCI status, although the association between anxiety and switching was strongest in participants with PD-MCI. These results suggest a possible common mechanism between anxiety and a specific aspect of executive functioning that should be evaluated in future research.

Increased use of mammography among hispanic women: Baseline results from the NCI cooperative group on cancer prevention in Hispanic communities

Background The Healthy People 2000 report set the objective of increasing the percentage of women 40 or older who had ever received a mammogram and clinical breast examination to 80% by the year 2000. The report used a baseline of 36% for all American women and 20% for Hispanic women. The purpose of this study was to compare baseline estimates with data obtained in five Hispanic communities. Methods Common survey measures were administered in five studies participating in a National Cancer Institute Cooperative agreement. The surveys evaluated history of mammography in five Hispanic communities in the southwestern Unites States. Results Across the five communities, the rates of mammography use were significantly higher than the national baseline. Among women 40-49 years of age, 55% had completed mammography (95% confidence interval [CI] = 52%, 57%). Among women 50 years of age or older, 64% had received a mammogram (95% CI = 62%, 66%). Older women (above age 50) were significantly more likely to have completed the test than younger women (younger than age 50), and mammography was obtained less often among women who were uninsured and those who had lower levels of acculturation. Conclusions We conclude that the rate of mammography use among Hispanic women has increased significantly over the last few years and that we are on track to reach the goal of 80% mammography compliance for Hispanic women 40 years and older by the year 2000.
Translation Attenuation by Minocycline Increases Lifespan and Improves Proteostasis in Old Post-Stress-Responsive Organisms

Aging impairs the activation of Stress Signaling Pathways (SSPs), preventing the induction of longevity mechanisms late in life. Here we show that the antibiotic minocycline increases lifespan and reduces protein aggregation even in old, SSP-deficient C. elegans by targeting cytoplasmic ribosomes, preferentially attenuating translation of highly translated mRNAs. In contrast to most other longevity paradigms, minocycline inhibits rather than activates all major SSPs and extends lifespan in mutants deficient in the activation of SSPs, lysosomal or autophagic pathways. We propose that minocycline lowers the concentration of newly synthesized aggregation-prone proteins, resulting in a relative increase in protein-folding capacity without the necessity to induce protein-folding pathways. Our study suggests that in old individuals with incapacitated SSPs or autophagic pathways, pharmacological attenuation of cytoplasmic translation is a promising strategy to reduce protein aggregation. Altogether, it provides a geroprotecive mechanism for the many beneficial effects of tetracyclines in models of neurodegenerative disease.
Re-experiencing 9/11-Related PTSD Symptoms Following Exposure to Hurricane Sandy

Background Understanding Pre-Existing Posttraumatic Stress Disorder (PTSD) symptoms and risk of PTSD following Hurricane Sandy (Sandy) has important implications for PTSD screening of persons exposed to multiple traumas. This study assessed the association between Sandy exposure and a subset of PTSD symptoms related to re-experiencing trauma from the events of the September 11, 2001 (9/11). Methods We studied 4,220 respondents from a random 8,870 person sample of adult World Trade Center Health Registry enrollees who completed a post-Sandy survey between March 28 and November 7, 2013. The symptom cluster of re-experiencing 9/11 was defined using 3 out of 5 questions in the intrusion domain of the PTSD Checklist. Multivariable logistic regression, adjusting for socio-demographics, social support and any post-9/11 life threatening events prior to Sandy, was performed separately in those symptomatic and non-symptomatic of re-experiencing 9/11 prior to Sandy. Results A total of 688 enrollees (16.3%) reported re-experiencing 9/11 symptoms after Sandy (58.8% in those symptomatic prior to Sandy, and 8.7% in those non-symptomatic). A significant association between Sandy exposure and re-experiencing 9/11 was observed only among those non symptomatic prior to Sandy (adjusted odds ratio (AOR)=1.7, 95% confidence interval=1.2-2.3 for moderate Sandy exposure; AOR=2.8, 2.0-4.0 for high Sandy exposure). Conclusions Individuals with a history of trauma should be considered for early screening and counseling for mental health after a subsequent traumatic event, regardless of PTSD status, especially in 9/11 exposed populations.

Coordinated Voltage Control Scheme of an Adjustable-Speed Pumped Storage Hydropower and a Wind Power Plant

As a type of inverter-based generation, an adjustable-speed pumped storage hydropower (AS-PSH) plant is a functional extension of conventional PSH plants and can provide more flexible and faster responses to provide ancillary services than conventional synchronous generators, thereby making a positive impact on power system voltage stability. This paper proposes a coordinated voltage control scheme of an AS-PSH plant with a wind power plant (WPP). The coordinated controller dispatches partial voltage set points, which are determined in proportion to the reactive current capability of each unit; thus, the controller enables the unit with a larger capability to receive a larger voltage set point so that the coordinating controller enhances the voltage controllability of the units. In addition, to stabilize the voltage at the point of interconnection after a fault clearance, reactive current initialization schemes are implemented in the AS-PSH and WPP controllers. The initialization schemes detect a sudden voltage rise (indicating the fault clearance) and enable the AS-PSH and WPP to rapidly reduce reactive current injections to the power system. The performance of the proposed scheme was tested for small and large voltage dips using PSCAD.
Ludwig Börne: A Memorial —A Double-Voiced Narrative of Exile

This chapter is arguably one of the most outstanding poetic expressions of modern exile. Ostensibly a memorial to Ludwig Borne, a fellow exile and prominent writer, this book has been praised as an exemplar of exquisite style and political insight and an exemplary reflection on the vicissitudes of life in exile. At the same time, it was scorned as an unfair and mean spirited attack on a compatriot with the same liberal and republican leanings as Heine. However, in an ironic way, this seeming attack turns into a double-voiced narrative, where Ludwig Borne often expresses the exact same ideas characteristic of Heine’s writing and in an equally witty fashion. Finally, this chapter offers both a brief overview of Heine’s prescient ideas about modern exile and a brief commentary on questions of censorship, exile, and fractures among diaspora communities.
Rational Synthesis of Unidimensional Mixed Valence Solids. Structure-Oxidation State-Charge Transport Relationships in Iodinated Nickel and Palladium Bisbenzoquinonedioximates.

Abstract : The results of the present investigation indicate that the M(bqd)2I(0.50) materials, M = Ni, Pd, are best formulated as M(bqd)2I(0.50).S materials where S represents various amounts of the aromatic solvent employed for crystallization. As deduced from resonance Raman, I-129 Mossbauer, and diffuse x-ray scattering measurements, the iodine is present as I3-, and thus the m(bqd)2I(0.50).S materials are indeed partially oxidized.
Differences in Health Care Utilization in the Year Before Suicide Death: A Population-Based Case-Control Study

Abstract Objective To compare health care usage between suicide decedents and living controls in the year before suicide in a large representative US population. Patients and Methods Cases (n=1221) and controls (n=3663) belonged to an integrated health care system from January 1, 2009, through December 31, 2014. Cases and controls were matched for age and sex in a 1:3 ratio, with diagnostic and/or billing codes used to enumerate and classify health care visits in the year before the index suicide. Matched analysis via conditional logistic regression related odds of suicide to visit type. A generalized estimating equation model was used to compare timing and frequency of visits between cases and controls. Results In the year before death, cases had an increased odds of both inpatient hospitalizations and emergency department nonmental health visits (odds ratio [OR], 1.55; 95% CI, 1.27-1.88; P Conclusion Compared with controls, suicide decedents had emergency department visits and more inpatient hospitalizations, both mental health and nonmental health related. As death approached, cases' frequency of health care usage increased. The only category in which cases and controls did not differ was in the frequency of outpatient nonmental health visits.

Diverticulitis in Morbidly Obese Adults: A Rise in Hospitalizations with Worse Outcomes According to National US Data.

Obesity is a known risk factor for diverticulitis. Our objective was to examine the less investigated impact of morbid obesity (MO) on admissions and clinical course of diverticulitis in a US representative database. We retrospectively queried the 2010–2014 Nationwide Readmission Database to compare diverticulitis hospitalizations in 48,651 MO and 841,381 non-obese patients. Outcomes of mortality, clinical course, surgical events, and readmissions were compared using multivariable and propensity-score-matched analyses. The number of MO patients admitted with diverticulitis increased annually from 7570 in 2010 to 11,935 in 2014, while the total number of patients admitted with diverticulitis decreased (p = 0.003). Multivariable analysis demonstrates that MO was associated with increased mortality (adjusted odds ratio [aOR] 1.54; 95% confidence internal [CI]: 1.16, 2.05), intensive care admissions (aOR = 1.92; 95% CI: 1.61, 2.31), emergent surgery (aOR = 1.20; 95% CI: 1.11, 1.30), colectomy (aOR = 1.13; 95% CI: 1.08, 1.18), open laparotomy (aOR = 1.28; 95% CI: 1.21, 1.34), and colostomy (aOR = 1.34; 95% CI: 1.25, 1.43). Additionally, MO was associated with higher risk for multiple readmissions for diverticulitis within 30 days (aOR = 1.45; 95% CI: 1.08, 1.96) and 6 months (aOR = 1.21; 95% CI: 1.03, 1.42). A one-to-one matched propensity-score analysis confirmed our multivariable analysis findings. Analysis of national data demonstrates an increasing trend of MO patients’ admissions for diverticulitis, with a presentation at a younger age. Furthermore, MO is associated with an increased risk of adverse outcomes and readmissions of diverticulitis. Future strategies are needed to ameliorate these outcomes.
Pregnancy and postpartum outcomes in a universally tested population for SARS-CoV-2 in New York City: a prospective cohort study.

OBJECTIVE: To describe differences in outcomes between pregnant women with and without coronavirus dsease 2019 (COVID-19). DESIGN: Prospective cohort study of pregnant women consecutively admitted for delivery, and universally tested via nasopharyngeal (NP) swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using reverse transcription-polymerase chain reaction. All infants of mothers with COVID-19 underwent SARS-CoV-2 testing. SETTING: Three New York City hospitals. POPULATION: Pregnant women >20 weeks of gestation admitted for delivery. METHODS: Data were stratified by SARS-CoV-2 result and symptomatic status, and were summarised using parametric and nonparametric tests. MAIN OUTCOME MEASURES: Prevalence and outcomes of maternal COVID-19, obstetric outcomes, neonatal SARS-CoV-2, placental pathology. RESULTS: Of 675 women admitted for delivery, 10.4% were positive for SARS-CoV-2, of whom 78.6% were asymptomatic. We observed differences in sociodemographics and comorbidities among women with symptomatic COVID-10 versus asymptomatic COVID-19 versus no COVID-19. Caesarean delivery rates were 46.7% in symptomatic COVID-19, 45.5% in asymptomatic COVID-19 and 30.9% in women without COVID-19 (P = 0.044). Postpartum complications (fever, hypoxia, readmission) occurred in 12.9% of women with COVID-19 versus 4.5% of women without COVID-19 (P < 0.001). No woman required mechanical ventilation, and no maternal deaths occurred. Among 71 infants tested, none were positive for SARS-CoV-2. Placental pathology demonstrated increased frequency of fetal vascular malperfusion, indicative of thrombi in fetal vessels, in women with COVID-19 versus women without COVID-19 (48.3% versus 11.3%, P < 0.001). CONCLUSION: Among pregnant women with COVID-19 at delivery, we observed increased caesarean delivery rates and increased frequency of maternal complications in the postpartum period. Additionally, intraplacental thrombi may have maternal and fetal implications for COVID-19 remote from delivery. TWEETABLE ABSTRACT: COVID-19 at delivery: more caesarean deliveries, postpartum complications and intraplacental thrombi.

The Strategic Evolution of Large U.S. Law Firms

In recent years, large US law firms have been undergoing significant changes. Most have switched from a professional model (P2 form) to a corporate business model, employing competitive strategies and a profit orientation. As the market for corporate legal services became more competitive, many large US law firms began to diversify the services they offer and expand their operations into new geographic regions of the country and into international markets. They even engaged in acquisitions and learned to manage and leverage their critical resources, human capital and relational capital. As a result, most of these law firms have added more professional management. All in all, the services law firms offer and the rivals with which they must contend have changed substantially over the last 15 years.
A Single Retrograde Intramedullary Nail Technique for Treatment of Displaced Proximal Humeral Fractures in Children: Case Series and Review of the Literature.

Displaced proximal humeral fractures in older children with low remodeling potential need to be reduced and fixed. There are many options for stabilization, including external fixation, rigid internal fixation with screws and plates, percutaneous pinning, and flexible intramedullary nailing. The use of 2 flexible retrograde nails, originated at the University of Nancy, France, became the most popular technique in Europe. The aim of this study was to describe and assess a modified, single retrograde nail technique to treat fractures of the proximal part of the humerus. Methods We performed a retrospective monocentric study. From June 2016 to May 2019, a modified retrograde nail technique with 1 prebent nail was used for the management of 21 consecutive children with a closed displaced proximal humeral fracture. Demographic and surgical data were collected. The surgical technique is similar to the classic elastic stable intramedullary nailing, but only 1 nail is used. The average surgical time and perioperative complications were used as criteria for the feasibility of this technique. Radiographs were obtained preoperatively; at 1, 4, and 6 weeks postoperatively; and after implant removal at an average of 4.2 months postoperatively. The clinical outcomes were assessed on the basis of the shoulder range of motion documented in the medical records and by using the French edition of the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) evaluation scale at the time of implant removal. Results Nineteen patients with a mean age of 12.6 years and a mean follow-up of 6 months were included in the study. The mean surgical time was 49 minutes. The single intramedullary nail technique provided a satisfactory reduction of all fractures. No perioperative complication occurred. In 1 case, partial loss of reduction was observed on the first-week control radiograph. All patients had a healed fracture, no deficits, excellent results according to the QuickDASH score, a normal range of motion, and excellent strength of the shoulder joint at the time of implant removal (at a mean of 4.2 months). Conclusions The current study confirms the feasibility and efficacy of the single retrograde intramedullary nail technique to treat displaced proximal humeral fractures in children.

Study of carbon supported CuPd alloy nanoparticles with Pd-rich surface for the electrochemical formate oxidation and CO2 reduction

Abstract Carbon supported copper-palladium alloy nanoparticles (CuPd/C) with Pd-rich surface synthesized via the adsorbate induced surface segregation method were tested toward both the electrochemical oxidation of formate into electricity and CO2, and the reduction of CO2 to produce formate. An upshift of the d-band center and opposite binding energy shifts of Cu and Pd core levels were experimentally observed using X-ray photoelectron spectroscopy (XPS). This perturbation of the surface electronic structure of the CuPd/C nanoparticles leads to the lowering of the bonding strength of key adsorbate species for both the formate oxidation and electrochemical CO2 reduction, which increased the catalytic activity toward both reactions. Amongst the different compositions of CuxPd1-x/C, the 20:80 molar% of Cu:Pd concentration shows an important improvement toward formate oxidation (FO) compared to the other CuxPd1-y compositions and the monometallic Pd. On the other hand, CuxPd1-x/C catalyst with the 60:40 molar% of Cu:Pd concentration shows the highest faradaic efficiency for the electrochemical CO2 reduction toward the formate production. Therefore, by selecting a bimetallic CuxPd1-x/C alloy that (1) optimizes the formate oxidation current density and (2) the faradaic efficiency of the electrochemical reduction of CO2 into formate, a novel sustainable and regenerative power source (i.e., combining a direct formate fuel cell and a CO2 reduction unit into a single regenerative energy system) could be developed.
