Epidemiological and Clinical Characteristics of 26 Asymptomatic Severe Acute Respiratory Syndrome Coronavirus 2 Carriers

We retrospectively analyzed 26 persistently asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) carriers. Epidemiological and clinical characteristics from the 26 asymptomatic patients with positive results for SARS-CoV-2 ribonucleic acid testing were obtained. Twenty-two patients (84.6%) correlated with clustering occurrence. The median period from contact to diagnosis and the last positive nucleic acid test was 19 (8–24 days) and 21.5 days (10–36 days), respectively. The median period from diagnosis to negative nucleic acid test was significantly different between patients with normal or atypical chest computed tomography (CT) findings (n = 16, 61.5%; 7.5 days [2–20 days]) and patients with typical ground-glass or patchy opacities on CT (n = 10, 38.5%; 12.5 days [8–22 days]; P < .01). Seven patients (70.0%) with initial positive nucleic acid test results had a negative result simultaneously with improved CT findings. Obvious improvement in CT findings was observed in 3 patients (30.0%) despite positive nucleic acid test results. In asymptomatic patients, changes in biochemical and inflammatory variables are small and changes on chest CT can occur. It is worth noting that the long existence of SARS-CoV-2 in some asymptomatic patients and false-negative results need to be considered in SARS-CoV-2 nucleic acid test.
Sexual selection rewires reproductive protein networks

Polyandry drives postcopulatory sexual selection (PCSS), resulting in rapid evolution of male ejaculate traits. Critical to male and female fitness, the ejaculate is known to contain rapidly evolving seminal fluid proteins (SFPs) produced by specialized male secretory accessory glands. The evidence that rapid evolution of some SFPs is driven by PCSS, however, is indirect, based on either plastic responses to changes in the sexual selection environment or correlative macroevolutionary patterns. Moreover, such studies focus on SFPs that represent but a small component of the accessory gland proteome. Neither how SFPs function with other reproductive proteins, nor how PCSS influences the underlying secretory tissue adaptations and content of the accessory gland, has been addressed at the level of the proteome. Here we directly test the hypothesis that PCSS results in rapid evolution of the entire male accessory gland proteome and protein networks by taking a system-level approach, combining divergent experimental evolution of PCSS in Drosophila pseudoobscura (Dpse), high resolution mass spectrometry (MS) and proteomic discovery, bioinformatics and population genetic analyses. We demonstrate that PCSS influences the abundance of over 200 accessory gland proteins, including SFPs. A small but significant number of these proteins display molecular signatures of positive selection. Divergent PCSS also results in fundamental and remarkably compartmentalized evolution of accessory gland protein networks in which males subjected to strong PCSS invest in protein networks that serve to increase protein production whereas males subjected to relaxed PCSS alters protein networks involved in protein surveillance and quality. These results directly demonstrate that PCSS is a key evolutionary driver that shapes not only individual reproductive proteins, but rewires entire reproductive protein networks.

When Do Partisans Stop Following the Leader?

ABSTRACT Evidence of public opinion blindly following political leader rhetoric has important implications for the scope of elite influence and normative democratic concerns. Past research, however, does not test the strength of real world leader cues amid signals that conflict with a leader’s policy message, and thus has not gauged sthe robustness of the “follow-the-leader” dynamic. The current study explores whether two different conflicting signals – 1) opposing intra-party Congressional elite cues and 2) negative policy information that gives compelling reasons to oppose a policy – attenuate leader influence in support of a realistic counter-stereotypical policy. A national survey experiment with two parallel partisan designs shows that individuals follow their leader to a substantial degree whether or not conflicting signals are present. Conflicting co-party elite cues do not attenuate leader influence among Republicans. For Democrats, although they weaken amid opposition, leader cues still shape mass opinion sizably. Providing substantially more information about the policy at hand does not make either partisan group much less likely to follow their leader, a finding that holds regardless of individuals’ preexisting ideology in the policy area. Results demonstrate the broad conditions under which “follow-the-leader” behavior holds and reveal a stronger nature of elite influence than previously understood. Party elites and information fail to effectively constrain the sway of prominent leaders, who have considerable latitude in positions they can take without losing mass support.
Political Accountability and Democratic Institutions: An Experimental Assessment

Abstract We study the extent to which centralized democratic institutions enhance collective action under political accountability. In a public goods game with costly punishment, we vary the appointment of one group member to enforce punishment. Specifically, we compare democratically elected punishers to those appointed exogenously, under both single- and multiple-selection environments. We find that democratically appointed sanctioning authority has muted effects on group outcomes; yet, they contribute as much as other group members when facing repeated elections, as opposed to the ones in single selection or exogenously appointed. One important feature of modern governance to discipline authorities is political accountability; when in place, it offers different incentives, and in particular, we observe a responsibility effect reflected in higher contribution behavior. Important in our study results, this effect rises only under a democracy.
Can Indirect Inflammatory Markers Differentiate Brucella Epididymo-Orchitis From Non-Brucella Epididymo-Orchitis?

Introduction : This study aimed to evaluate the value of direct and indirect markers showing inflammation in the diagnosis of Brucella epididymo-orchitis (BEO) and its differentiation from non-Brucella epididymo-orchitis. Materials and Methods : A total of 152 patients that presented to our clinic with acute scrotal complaints and were diagnosed with epididymo-orchitis between January 2015 and January 2019 were retrospectively evaluated. Excluded from the study were 15 patients with a hematologic disease, coronary artery disease or malignant diagnosis, eight patients aged below 18 years, and 13 patients whose hemogram and C-reactive protein (CRP) values were not available in their medical records. The diagnosis of epididymo-orchitis was based on laboratory (leukocytosis, CRP elevation) and radiological findings. The diagnosis of BEO was defined as ≥1/160 titer value and/or positive blood culture in the standard tube agglutination (STA) test in addition to orchitis symptoms and signs. Results : The median WBC (p=0.033), neutrophil (p=0.013) and monocyte (p=0.006) counts and NL (p=0.014) and ML (p=0.002) ratios were statistically significantly lower in the BEO group. The ML ratio had the highest predictive value with an AUC of 0.725 (95% CI = 0.146-0.424; p=0.002), as well as high specificity (97.3%) and diagnostic accuracy (83.5%) in predicting a BEO diagnosis. No parameter was an independent factor in the differentiation of BEO and NBEO. Conclusions : Easy, fast and low-cost hemotological inflammatory markers provide diagnostic benefits complementing serological tests in distinguishing BEO from NBEO cases. In particular, the ML ratio has a high diagnostic accuracy rate compared to other parameters.

Analysis on the Effect of Ball Pressure on Head Acceleration to Ensure Safety in Soccer

Soccer/football is one of the most popular sports in the world. Any sport requires continuous adjustments to rules to keep the game safe and engaging. Increased awareness of concussions in the American National Football League (NFL) has consequently raised attention to concussion-related injuries in other sports. One of the first steps the United States Soccer Federation (USSF) has taken to reduce head injuries is to implement age restrictions on heading. This encourages safer play but discourages an important skill until players are a certain age which is not good for player development. An alternative is to ensure mean head acceleration from a header is reduced with minimal rule changes. This paper presents a dynamic model of a player heading a soccer ball to examine the general relationship between ball pressure and mean head acceleration toward the purpose of motivating a more complex and comprehensive analysis of heading in soccer.
The impact of digitalization and servitization on the financial performance of a firm: an empirical analysis

Abstract Manufacturing firms have vigorously pursued opportunities for profitability and growth through servitization and digitalization processes. However, the current body of research provides contradictory results on the impact of servitization and digitalization on firm financial performance. This paper seeks to address how manufacturing companies can turn technology into business process transformation. To address this gap this paper develops and tests a framework for assessing the impact of servitization and digitalization on firm financial performance. This study analyses a survey of 185 U.S. and European manufacturing firms showing empirical evidence that digitalization and servitization had a direct positive effect on a firm’s financial performance. This research gives managers some insights to better understand the digital transformation in servitization process. These results also have significant theoretical implications to the servitization literature, since achieving superior bottom-line results is contingent on the integration of the digital and service-specific capabilities that reinvent the nature of an offering.
Extraction of carboxylic acids by amine extractants

This work examines the chemistry of solvent extraction by long-chain amines for recovery of carboxylic acids from dilute aqueous solution. Long-chain amines act as complexing agents with the acid, which facilitates distribution of the acid into the organic phase. The complexation is reversible, allowing for recovery of the acid from the organic phase and regeneration of the extractant. Batch extraction experiments were performed to study the complexation of acetic, lactic, succinic, malonic, fumaric, and maleic acids with Alamine 336, an aliphatic, tertiary amine extractant, dissolved in various diluents. Results were interpreted by a ''chemical'' model, in which stoichiometric ratios of acid and amine molecules are assumed to form complexes in the solvent phase. From fitting of the extraction data, the stoichiometry of complexes formed and the corresponding equilibrium constants were obtained. The results of the model were combined with infrared spectroscopic experiments and results of past studies to analyze the chemical interactions that are responsible for extraction behavior. The information from the equilibrium studies was used to develop guidelines for large-scale staged extraction and regeneration schemes. A novel scheme, in which the diluent composition is shifted between extraction and regeneration, was developed which could achieve both high solute recovery andmore » high product concentration. 169 refs., 57 figs., 15 tabs. « less
Pretransplant C-reactive protein, ferritin, albumin, and platelet count as prognostic biomarkers of hematopoietic stem cell transplantation outcome in hematological malignancies

Aim To study the prediction of prognosis after hematopoietic stem cell transplantation (HSCT) by clinically available biomarkers prior to transplantation (CRP, Ferritin, albumin and platelet count). Background Previous studies have shown that a number of objective laboratory “biomarkers” are of interest in pre-HSCT risk-assessment: Serum albumin inversely correlates with age, smoking, obesity and hypertension, and predicts cardiovascular mortality. Serum ferritin is an acute phase reactant, and elevated levels suggest iron overload, which has been linked to post-HSCT infections. Finally low platelet count, could indicate poor marrow function related to persistent malignancy or effects of prior treatment. Methods The study included patients admitted at the Bone marrow transplantation Units in Egypt (Ain Shams University Hospitals and Maadi Armed Forces Medical Compound and Sheikh Zayed Specialized Hospital) between August 2015 and December 2016. The study population consisted of 30 adults aged from 18 to 60 years; 26 patients were subjected to autologous-HSCT to treat high-risk or relapsing NHL, MM, relapsing HL, and 4 patients subjected to allogeneic-HSCT to treat 1st complete remissiom (CR) AML, 2nd CR AML. The biomarkers included pre-transplant serum albumin, platelet count, C-reactive protein (CRP) and serum ferritin were centrally quantified by (ELISA) technique. All patients were followed up till day +90 post transplant. Results Shock developed post-transplant in patients with CRP ˃10 mg/L (P=0.026) while non-relapse mortality was associated with the pre-specified thresholds of platelet count <150,000/μl (P=0.046) but not CRP ˃10 mg/L (P=0.1) and s.albumin <3.5 g/dL (P=0.3) and s.ferritin <2500 ng/mL. (P=0.9). Three months overall survival (OS) was 87% among the studied group. Mean survival time was associated with low platelet count <150,000/μl (P=0.024) not with CRP ˃10 mg/L (P=0.1) and s.albumin <3.5 g/dL (P=0.6) and s.ferritin <2500 ng/mL (P=0.9). Conclusion We conclude that elevated level of pre-transplant CRP, s.ferritin associated with high NRM without statistically significant difference while NRM was higher in patients with normal s.albumin pre-transplant without statistically significant difference, low platelet count <150,000/μl associated with increased NRM with statistically significant difference (P=0.046), and lower survival the 3 months overall survival (OS) among patients was about 87%. Mean survival time was statistically significant in patients with low platelet count (P=0.024) not in CRP, ferritin and albumin.

Alcohol consumption among university students: The case of Ondokuz Mayıs University

The consumption of alcohol has become more common worldwide, including among university students, due to easy access, liberal environment for drinking, low level of parental control, social equality and peer group pressure. This study analyses the factors affecting alcohol consumption by university students in Turkey. The purpose of the research was to understand how the students habituated to consuming alcohol, especially by evaluating social activities, cultural and social norms in drinking patterns. The research data were collected from 384 students who answered questionnaires at Ondokuz Mayıs University in Samsun Province, Turkey. The Chi -square test was used to analyze the data. The study showed that socio-demographic factors, namely age, gender, marital status, idols’ using alcohol, household size, household income, accommodation, parental drinking status, residential area and smoking, were statistically significant factors for alcohol consumption and therefore played an important role in alcohol consumption by students. This study showed that public and non-governmental organizations should organize programs to educate students about harmful drinking, and also future decisions about student’s alcohol consumption can be renewed by the laws.

Rising and sinking intruders in dense granular flows

We computationally determine the force on single spherical intruder particles in sheared granular flows as a function of particle size, particle density, shear rate, overburden pressure, and gravitational acceleration. The force scales similarly to, but deviates from, the buoyancy force predicted by Archimedes' principle. The deviation depends only on the intruder to bed particle size ratio, but not the density ratio or flow conditions. We propose a simple force model that successfully predicts whether intruders rise or sink, knowing only the size and density ratios, for a variety of flow configurations in physical experiments.
MONTE-CARLO UNCERTAINTY EVALUATION OF TRANSFER STANDARDS FOR ATOMIC FORCE MICROSCOPY

Atomic force microscopes (AFMs) are frequently used to measure surface features and parameters. The traceable calibration of images obtained is a pre-requisite for establishing the uncertainty associated with such a measurement and to be used in quality assurance processes. For this purpose, the typical procedures for the calibration of these instruments use transfer standards, which typically consist on gratings produced using optical lithography with x-y-z dimensions traceable to a national laboratory [1 - 3]. In this way, the traceability chain for AFM instruments is the following: meter – laser interferometry – MAFM (metrologic AFM with displacements measured by means of laser interferometry) – transfer standard – AFM. In this work, we will estimate the uncertainty of a typical transfer standard for AFM calibration using a Monte-Carlo technique. This procedure appears very useful specially when model equations are complicated and the sensitivity coefficients are difficult to obtain. Uncertainty budget and model equations (xy and z) for the calculations are obtained from bibliographic data [4], where the gratting calibration was made using a MAFM. Next we describe equations, standard uncertainty and type of distribution for each term: xymf xydp xyAbbe xyt xym xya xy xy L
