Abstract

Objectives
Patients hospitalized because of community-acquired-pneumonia (CAP) are at risk of cardiovascular diseases. Although plasma procoagulant imbalance play a role, mechanisms are not completely understood. We aimed to investigate whether there is a measurable state of procoagulant imbalance following inflammation determined by CAP.

Methods
We analyzed blood from 51 CAP patients at admission and 51 healthy subjects (HS) for (i) pro and anticoagulants, (ii) thrombin generation (TG) with or without thrombomodulin (TM), which is the physiologic activator of the protein C anticoagulant pathway and(iii) by assessing the ratio between von Willebrand-factor (VWF) and its protease ADAMTS13. Thirty patients were re-analyzed one month after discharge when CAP was resolved.

Results
Median levels of TG parameters, including the endogenous thrombin potential (ETP), the ETP-TM-ratio (with/without TM), peak-thrombin and velocity index were higher in patients at baseline than HS. In particular, the median (IQR) ETP-TM-ratio in patients vs. HS was 0.88 (0.83–0.91) vs. 0.63 (0.48–0.71), p<0.001. Factor (F)VIII, a potent procoagulant involved in TG was higher in patients at baseline than HS [195 U/dL (100–388) vs. 127(108–145)], p<0.001]. The ratio of VWF/ADAMTS13 was higher at baseline than HS. Cumulatively, the findings indicate a state of pro-coagulant imbalance, which (although reduced), remained high [i.e., ETP-TM-ratio, 0.80 (0.74–0.84); FVIII, 152 U/dL (122–190)] one month after discharge when the infection was resolved.

Conclusions
Patients with CAP possess a state of pro-coagulant imbalance, which remains substantially high, even when the infection is resolved. The findings suggest CAP patients as candidates for antithrombotic prophylaxis even after the resolution of infection. Clinical trials are warranted to assess the benefit/risk ratio of prophylaxis extension.

Abstract
In this paper,we introduce and study a new subclass of meromorphic functions associated with a certain differential operator on Hilbert space. For this class, we obtain several properties like the coefficient inequality, growth and distortion theorem, radius of close-to-convexity, starlikeness and meromorphically convexity and integral transforms. Further, it is shown that this class is closed under convex linear combinations.
Lexical stress assignment preferences in L2 German
Authors: O’Brien Mary Grantham , Sundberg Ross 
Published: June 2021

Abstract
Assigning stress to the appropriate syllable is consequential for being understood. Despite the importance, second language (L2) learners’ stress assignment is often incorrect, being affected by their first language (L1). Beyond the L1, learners’ lexical stress assignment may depend on analogy with other words in their lexicon. The current study investigates the respective roles of the L1 (English, French) and analogy in L2 German lexical stress assignment. Because English, like German, has variable stress assignment and French does not, participants included English- and French-speaking German L2 learners who assigned stress to German nonsense words in a perceptual preference and a production task. Results suggest a role of the L1, with English-speaking German L2 learners performing more like L1 German speakers. While French-speaking German L2 learners’ performance could not be predicted by other factors, L2 German proficiency and the ability to produce analogous words were predictive of English-speaking German L2 learners’ production performance.

AbstractLarge amount of data are exchanged and the internet is turning into twenty-first century Silk Road for data. Machine learning (ML) is the new area for the applications. The artificial intelligence (AI) is the field providing machines with intelligence. In the last decades, more developments have been made in the field of ML and deep learning. The technology and other advanced algorithms are implemented into more computational constrained devices. The online English test system based on ML breaks the shackles of the traditional paper English test and improves the efficiency of the English test. At the same time, it also maintains the fairness of English test and improves the marking speed. In order to realize an online English test system based on ML and facilitate the assessment of students’ college English courses, this paper mainly adopts relevant research and design on the main functional modules, key technologies, and functional realization of the online English test. The brand-new powerful teaching software and the online examination system can help schools to conduct more systematic and scientific management. The conclusion shows that as brand-new and powerful teaching software, the online examination system can help schools to conduct more systematic and scientific management.

Future directions of chemical theory and computation
Authors: Lu Yuyuan , Deng Geng , Shuai Zhigang 
Published: June 2021

Abstract
Theoretical and computational chemistry aims to develop chemical theory and to apply numerical computation and simulation to reveal the mechanism behind complex chemical phenomena via quantum theory and statistical mechanics. Computation is the third pillar of scientific research together with theory and experiment. Computation enables scientists to test, discover, and build models/theories of the corresponding chemical phenomena. Theoretical and computational chemistry has been advanced to a new era due to the development of high-performance computational facilities and artificial intelligence approaches. The tendency to merge electronic structural theory with quantum chemical dynamics and statistical mechanics is of increasing interest because of the rapid development of on-the-fly dynamic simulations for complex systems plus low-scaling electronic structural theory. Another challenging issue lies in the transition from order to disorder, from thermodynamics to dynamics, and from equilibrium to non-equilibrium. Despite an increasingly rapid emergence of advances in computational power, detailed criteria for databases, effective data sharing strategies, and deep learning workflows have yet to be developed. Here, we outline some challenges and limitations of the current artificial intelligence approaches with an outlook on the potential future directions for chemistry in the big data era.
Metal complex pigments
Authors: Christie Robert , Abel Adrian 
Published: June 2021

AbstractThere are several commercially significant metal complex organic pigments that are based on first row transition metals. The most important of these are the copper phthalocyanine blue and green pigments which find virtually universal use in paints, printing inks, and plastics. These pigments are of such prime importance that they are dealt with separately in three other chapters in this series. This paper describes a group of pigments that are complexes of iron, copper, nickel, and cobalt with polydentate colored ligands of azo, azomethine, oxime, and isoindoline chemical types. The oldest metal complex organic pigment that still finds some use is CI Pigment Green 8, an octahedral oxime iron complex. In the 1970s and 1980s, there was considerable industrial research effort aimed at developing metal complex pigments based on azomethine and isoindoline structures, many of which were found to offer excellent lightfastness, good solvent resistance and thermal stability, although they exhibited rather dull colors. However, several products provide brilliant effects when used in combination with metallic and pearlescent pigments in automotive paints. Many of the pigments introduced have since been withdrawn by the original manufacturers, but a few remain on the market. The synthesis of metal complex pigments generally involves the preparation of the colored ligand, which is then complexed with the transition metal ion
Introduction: Using Placebo Research to Explore Belief and Healing in Late Antiquity
Authors: Korsvoll Nils H. 
Published: June 2021

AbstractThis special issue explores belief and healing in Late Antiquity, through insight and terminology developed in modern placebo research. My introduction outlines the history of placebo research and its use in historical studies of medicine and healing. It has helped historians pose new questions to their sources and discuss them in light of modern medical research. Most studies analyse various descriptions or records of symptoms or diagnoses, but some researchers also extend their work to include social or anthropological studies of healing. Summarizing insights from such efforts in medical research and the history of medicine, I propose a selection of questions and perspectives from research on the placebo effect to aid and guide the subsequent articles in their examination of their respective sets of sources, as well as facilitate discussion and comparison across our different materials, and often also differing disciplines.
Hope for Cure and the Placebo Effect: The Case of the Greco-Egyptian Iatromagical Formularies
Authors: Sarischouli Panagiota 
Published: June 2021

AbstractThe present paper focuses on healing rituals from Greco-Roman Egypt, where medicine and religion were inextricably linked to each other and further connected to the art of magic. In Pharaonic Egypt, healing magic was especially attributed to the priests who served a fearsome goddess named Sekhmet; although Sekhmet was associated with war and retribution, she was also believed to be able to avert plague and cure disease. It then comes as no surprise that the majority of healing spells or other types of iatromagical papyri dating from the Roman period are written in Demotic, following a long tradition of ancient Egyptian curative magic. The extant healing rituals written in Greek also show substantial Egyptian influence in both methodological structure and motifs, thus confirming the widely accepted assumption that many features of Greco-Egyptian magic were actually inherited from their ancient antecedents. What is particularly interesting about these texts is that, in many cases, they contain magical rites combined with basic elements of real medical treatment. Obviously, magic was not simply expected to serve as a substitute for medical cure, but was rather seen as a complementary treatment in order to balance the effect of fear, on the one hand, and the flame of hope, on the other.
On the Latin-Romance continuum in theDurham Account Rolls
Authors: Roig-Marín Amanda 
Published: June 2021

AbstractThis article provides an overview of the Romance-Latin continuum, inherent to theDurham Account Rolls(DAR), and contextualises the learning and teaching of French and Latin in medieval England: an understanding of the socio-historical context and the underlying pedagogical framework enables us to better assess the data presented in this article. In line with a detriment to the learning of French in the late 14th century and a progressive loss of linguistic competence, the definite article in these multilingual texts started to develop an independent course from its French model which is herein discussed. The parameters for identifying lexis as coming only from French, Latin, or both are also revisited. The occurrences in the DAR usually encompass a whole spectrum of possible morphological manifestations ranging from Latin to French. This article concludes with some notes on the main semantic domains to which Anglo-French contributed in the DAR.
La discordancia de número en el doblado de objeto indirecto: nuevos datos del español de Galicia
Authors: Sanromán Vilas Begoña 
Published: June 2021

AbstractThe article analyses the loss of agreement between the dative clitic and its plural nominal referent in indirect object clitic-doubling in Spanish spoken in Galicia. On the basis of the previously defended hypothesis that number disagreement makes part of a grammaticalisation process whereby the clitic becomes a case affix, the paper examines some internal factors which lack consensus in previous studies, such as the relation between (in)transitivity and position of the clitic or animacity of nominal referents of the IO, and other external factors. Data analysis reveals that the percentage of disagreement in this area is much higher than in other Spanish speaking areas. This fact might be a consequence of language contact with Galician, a language where number inflection in the dative clitic is neutralised. To verify this hypothesis, the paper explores the relation between the number of occurrences of disagreement and the level of bilingualism of the speakers.
Time to Be Negative About Acceleration: A Spotlight on Female Football Players

Abstract
Griffin, J, Horan, S, Keogh, J, Andreatta, M, and Minahan, C. Time to be negative about acceleration: A spotlight on female football players. J Strength Cond Res 36(11): 3264–3271, 2022—Women's football requires players to perform frequent changes in velocity (i.e., speed and direction) for successful performance. Although increases in velocity (“acceleration”) are important, decreases in velocity (“deceleration”) should also be considered equally important to performance and load monitoring. Currently, there is a disproportionate focus on acceleration and creating faster players. The aim of this review is to provide an understanding of deceleration for female football players. Given the limited research in this area, data from studies involving male football players and from other team-sport athletes were used to supplement the review where necessary. Most research focused on eccentric strength and its relationship with deceleration ability, highlighting the importance of slow eccentric strength of the quadriceps and hamstrings to deceleration. Technical and kinematic characteristics of deceleration were also investigated. Importantly, with deceleration being a unilateral motor skill, development requires similar amounts of training for both legs. Imbalances between legs in skill and strength characteristics may compromise performance or increase the risk of injury. Given the dependent nature of deceleration, several contextual factors were identified as important when considering deceleration as a part of training programs and performance. Deceleration is affected by the following factors: an athlete's momentum, the approach speed, change of direction angle, time or distance, anticipated or unanticipated task, fatigue, and the positional requirements of female football players. Further research is needed into deceleration and the physical characteristics associated with deceleration performance, particularly for female football players.

Abstract
Oliva-Lozano, JM, Martín-Fuentes, I, Granero-Gil, P, and Muyor, JM. Monitoring elite soccer players physical performance using real-time data generated by electronic performance and tracking systems. J Strength Cond Res 36(11): 3224–3228, 2022—The aims of this technical report were to analyze the validity of real-time data collected by electronic performance and tracking systems (EPTS) and investigate the effect of varying real-time receiver's position on the real-time data collected. Physical performance data were collected from professional soccer players using EPTS. In addition, 3 real-time receivers, which were placed in different positions (i.e., central area of the stadium stands and right and left technical areas), were used to collect real-time data. The real-time data collected by each receiver were visualized on SVivo and compared with the data downloaded directly from the device on SPro. The results showed no statistically significant differences between the data collected by the real-time receivers compared with postsession data in any variable (p > 0.05), except for total distance and high-speed running distance covered, which showed significant differences but trivial effect size (p < 0.05; d = 0.01). The coefficient of determination (R
2) and intraclass correlation coefficient were greater than 0.97 and 0.99, respectively. Regarding the analysis of varying the receiver's position on the real-time data collected, the results showed that there was no significant effect of the receiver's position on any variable (p > 0.05). Therefore, valid physical performance data may be obtained by real-time tracking systems such as SVivo, regardless of the position of the real-time receivers and distance to the players. Specifically, high-intensity running actions, distances covered at low and high speed, and accelerometer-derived variables such as player load may be accurately tracked by this real-time tracking software.

OBJECTIVES
To determine the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in infants hospitalized for a serious bacterial infection (SBI) evaluation and clinically characterize young infants with SARS-CoV-2 infection.

METHODS
A retrospective chart review was conducted on infants &lt;90 days of age hospitalized for an SBI evaluation. The study was conducted at 4 inpatient facilities in New York City from March 15, 2020, to December 15, 2020.

RESULTS
We identified 148 SBI evaluation infants who met inclusion criteria. A total of 22 infants (15%) tested positive for SARS-CoV-2 by nasopharyngeal reverse transcription polymerase chain reaction; 31% of infants admitted during periods of high community SARS-CoV-2 circulation tested positive for SARS-CoV-2, compared with 3% when community SARS-CoV-2 circulation was low (P &lt; .001). The mean age of infants with SARS-CoV-2 was higher than that of SARS-CoV-2–negative infants (33 [SD: 17] days vs 23 [SD: 23] days, respectively; P = .03), although no age difference was observed when analysis was limited only to febrile infants. An isolated fever was the most common presentation of SARS-CoV-2 (n = 13; 59%). Admitted infants with SARS-CoV-2 were less likely to have positive urine culture results (n = 1 [5%] versus n = 25 [20%], respectively; P = .002), positive cerebrospinal culture results (n = 0 [0%] versus n = 5 [4%], respectively; P = .02), or be admitted to intensive care (n = 2 [9%] versus n = 47 [37%]; P &lt; .001), compared with infants without SARS-CoV-2.

CONCLUSIONS
SARS-CoV-2 was common among young infants hospitalized for an SBI evaluation during periods of high but not low community SARS-CoV-2 circulation in New York City, although most infants did not require intensive care admission.

Trichuris vulpis and Toxocara canis are worldwide parasitic nematodes affecting dogs and mammals of the Canine family. Due to the special structure of the shells, the eggs of these geohelminths can maintain their viability in soil, sand, water and the environment for a long time. The study involved young (6–12 months old) and adult (1.5–8.0 years old) dogs affected by co-infection of T. vulpis + T. canis; the control group consisted of dewormed healthy animals of the same age. Parasitological examination of dogs' faeces was performed using a "Counting Chamber for Ovoscopic Researches"; morphological parameters, indicators of nutrient metabolism, mineral metabolism and activity of enzymatic systems were determined in blood and serum. According to the results of parasitological research on the dogs, it was found that young animals are more prone to toxocarosis, and adults – trichurosis. The co-infection of nematodes T. vulpis + T. canis in dogs develops several changes in haematological parameters: a significant decrease in erythrocytes, haemoglobin, MCV, MCH, and haematocrit, leukocytosis with basophils and eosinophilia in young infected animals; and eosinophilia and basophilia (15.9 times) in adults, compared with healthy dogs of the same age. Among the changes in serum biochemical parameters, young infected dogs showed a decrease in the concentration of total protein and albumin content, an increase in the content of "acute phase" proteins (α-1, α-2 and β-globulins), an increase in cholesterol and total bilirubin; in adult infected dogs, a decrease in albumin content, an increase in the content of α-1, α-2, and β-globulins, an increase in the concentration of cholesterol and total bilirubin, a decrease in the concentration of urea in comparison with healthy animals were determined. Also, among the indicators of mineral metabolism, a decrease in the concentration of calcium and magnesium in the serum was found in young infected dogs. Among the changes in the enzyme metabolism in the serum of infected dogs, there was an increase in the activity of all studied enzymes in animals of both research groups: ALT, AST, α-amylase, GGT and ALP. Thus, co-infection with nematodes T. vulpis + T. canis has a complex pathogenic effect on the body of dogs of all ages, which manifested itself in multiple changes in haematological parameters. In the future, the authors’ team plan to develop comprehensive measures to combat nematode infections in different living conditions of dogs, taking into account the results of the current research.
Stiffness matrices for layered soils
Authors: Kausel Eduardo , Roësset José Manuel 
Published: June 2021

AbstractThe Haskell-Thompson transfer matrix method is used to derive layer stiffness matrices which may be interpreted and applied in the same way as stiffness matrices in conventional structural analysis. These layer stiffness matrices have several advantages over the more usual transfer matrices: (1) they are symmetric; (2) fewer operations are required for analysis; (3) there is an easier treatment of multiple loadings; (4) substructuring techniques are readily applicable; and (5) asymptotic expressions follow naturally from the expressions (very thick layers; high frequencies, etc.). While the technique presented is not more powerful than the original Haskell-Thompson scheme, it is nevertheless an elegant complement to it. The exact expressions are given for the matrices, as well as approximations for thin layers. Also, simple examples of application are presented to illustrate the use of the method.
