ELLIPTIC SURFACES AND ARITHMETIC EQUIDISTRIBUTION FOR R-DIVISORS ON CURVES LAURA DE MARCO AND NIKI MYRTO MAVRAKI

Suppose E → B is a non-isotrivial elliptic surface defined over a number field, for smooth projective curve B. Let k denote the function field Q(B) and E the associated elliptic curve over k. In this article, we construct adelically metrized R-divisors DX on the base curve B over a number field, for each X ∈ E(k) ⊗ R. We prove non-degeneracy of the Arakelov-Zhang intersection numbers DX · DY , as a biquadratic form on E(k) ⊗ R. As a consequence, we have the following Bogomolov-type statement for the NéronTate height functions on the fibers Et(Q) of E over t ∈ B(Q): given points P1, . , Pm ∈ E(k) with m ≥ 2, there exist a non-repeating infinite sequence tn ∈ B(Q) and smallheight perturbations P ′ i,tn ∈ Etn(Q) of specializations Pi,tn so that the set {P ′ 1,tn , . , P ′ m,tn} satisfies at least two independent linear relations for all n, if and only if the points P1, . , Pm are linearly dependent in E(k). This gives a new proof of results of Masser and Zannier [MZ1, MZ2] and of Barroero and Capuano [BC] and extends our earlier results [DM]. We also prove a general equidistribution theorem for adelically metrized R-divisors on curves (over a number field), extending the equidistribution theorems of Chambert-Loir, Thuillier, and Yuan [CL1, Th, Yu], and using results of Moriwaki [Mo2].
Clinical Outcomes and influence factors of differentiated thyroid carcinoma with negative preablative stimulated thyroglobulin and iodine-positive lymph nodes: A retrospective analysis

Background To investigate the clinical outcome of postoperative differentiated thyroid carcinoma(DTC)patients with negative preablative-stimulated thyroglobulin (ps-Tg) and iodine-positive lymph node after the first radioablation. Methods A total of 136 DTC patients with ps-Tg<2ng/ml and iodine-positive lymph nodeswho were initially treated by 131I at our hospital from May 2015 to February 2018 were enrolled. These patients were followed up for 6-36 months, and then were classified into 3 groups according to the clinical outcomes as follows: excellent response (ER) group, indeterminate response (IDR) group, and structural incomplete response (SIR) group.Univariate and multivariate analyses were performed to assess thedifferences of factors (e.g. age, gender, extraglandular infiltration) between 3 groups. Results The N stage (P=0.001), sizes of the displayed lymph nodes (P<0.001), ps-Tg level (P=0.002), and TgAb level (P=0.001) were significantly different among the 3 groups. The gender (P=0.615), age (P=0.332), the primary tumor size (P=0.311), extrathyroidal invasion (P=0.549), T stage (P=0.944), rate of lymph node metastasis (P=0.170), locations of the displayed lymph nodes (P=0.099), and degree of recurrence risk (P=0.783) were not significantly different among the 3 groups.The corresponding sensitivity, specificity, positive predictive value, and negative predictive values were 93.3%, 82.6%, 86.4%, and 91.3% respectively when the cut-off value of the lymph node size was 7.25 mm. Conclusion For the DTC patients with negative ps-Tg and iodine-positive lymph nodes, postoperative N stage, size of the displayed lymph nodes, and ps-Tg and TgAb levels could be used as sensitive indicators for predicting clinical outcomes.
Trends in U.S. Spatial Inequality: Concentrating Affluence and a Democratization of Poverty

We use Bureau of Economic Analysis, census, and Current Population Survey data to study trends in income inequality across US states and counties from 1960-2019. Both states and counties have diverged in terms of per capita pretax incomes since the late1990s, with transfers serving to dampen this divergence. County incomes have been diverging since the late 1970s. These trends in mean income mask opposing patterns among top-and bottom-income quantiles. Top incomes have diverged markedly across states since the late 1970s. In contrast, bottom-income quantiles and poverty rates have converged across areas in recent decades.
The Effect of Etymological Elaboration, Pictorial Elucidation, and Podcasting on Comprehension of Idioms

This study investigated the effect of three idiom learning strategies; etymological elaboration, pictorial elucidation, and podcasting on idiom comprehension by the EFL learners. A total number of 60 homogeneous upper-intermediate learners studying English in Shiva language institute in Qom, Iran, were selected based on the result of Oxford Placement Test (OPT). After applying the Test, the attendees were randomly divided into three groups of almost equal size and took a thirty-item pretest to ensure their unfamiliarity with the idioms. The idioms that were familiar even to one attendee were eliminated and at last 30 idioms were chosen for the instruction. Then, the etymological elaboration, pictorial elucidation, and podcasting groups received their relevant treatments during 10 sessions. After the implementation of the experiment, the researcher administered the posttest to examine the influence of these strategies on idiom comprehension. Finally, the data were analyzed by one-way ANOVA. The results proved that etymological elaboration strategy was the less effective technique in developing learners’ idiom comprehension and the two techniques of pictorial elucidation and podcasting had equal degree of impact in leading to learners’ idiom comprehension.

An accurate multireference configuration interaction calculation of the potential energy surface for the F+H2→HF+H reaction

A three dimensional potential energy surface for the F+H2→HF+H reaction has been computed using the internally contracted multireference configuration interaction (MRCI) method with complete active space self‐consistent field (CASSCF) reference functions and a very large basis set. Calibration calculations have been performed using the triple‐zeta plus polarization basis set employed in previous nine‐electron full CI (FCI) calculations of Knowles, Stark, and Werner [Chem. Phys. Lett. 185, 555 (1991)]. While all variational MRCI wave functions yield considerably larger barrier heights than the FCI, excellent agreement with the FCI barrier height and the exothermicity was obtained when the Davidson correction was applied (MRCI+Q). The convergence of the barrier height and exothermicity, spectroscopic constants of the HF and H2 fragments, and the electron affinity of the fluorine atom with respect to the basis set has been carefully tested. Using the largest basis sets, which included 5d, 4f, 3g, and 2h func.
Assessment of Health-Related Quality of Life and Medication Adherence In Tuberculosis Patients

Tuberculosis (TB) is an infectious disease caused by bacteria called Mycobacterium tuberculosis. The disease mainly affects lungs and causes pulmonary tuberculosis. It can also affect intestine, meninges, skin, bones and other tissues of the body. Although the drugs alone can cure TB, it still remains a major public health problem worldwide. The aim of the study was to assess the quality of life and medication adherence in TB patients. The Quality of life was assessed using SF-36 in patients receiving DOTS treatment in initial or continuous phase while the medication adherence was analyzed using Morisky Green Levine Scale. Subjects were also counselled about their disease during their first visit and a follow up was done after a month. A total of 152 subjects were enrolled in the study of which majority of the subjects had Pulmonary TB (55.26%). Diabetes was found to be the most common comorbidity followed by HTN. The average Physical Component Summary (PCS) and Mental component summary (MCS) were found to be 44.34 and 39.60 respectively. Females had a better quality of life scores compared to males. High adherence was seen in 32.24% of patients while 28.29% had low adherence. Follow up was done for 135 subjects. 15 subjects defaulted and 2 of them died. There was a significant increase in the QoL scores and medication adherence after one month. A significant association was found between the Physical functioning (p=0.001) and emotional wellbeing (p=0.01) with Duration of treatment indicating that subjects who had completed more than one month of their treatment had marked improvement in Physical functioning and emotional well-being scores.
Effects of dried water melon and sweet orange peel (dwmop) meal mixture on the haematological and serum indices of growing rabbits

The objective of the present study was to evaluate effects of dried water melon and sweet orange peel (dwmop) meal mixture on some haematological and serum indices of growing rabbits. A total of sixty rabbits 7-8 weeks old with an average weight of 630 – 645 g were randomly divided into five (5) dietary treatments with three (3) replicates and four rabbits per replicate in a Completely Randomized Design (CRD). The dietary treatments include a control diet with no DWMOP in (T1), T2 (5.0% DWMOP), T3 (10.0 % DWMOP), T4 (15.0 % DWMOP) and T5 (20.0 % DWMOP) respectively. Feed and water were offered ad libitum throughout the experiment which lasted for 12 weeks. Data obtained were used to evaluate the haematological parameters (PCV, RBC, Hb, MCV, MCH , MCHC, WBC and its differentials ), some serum biochemical indices (Albumin, globulin, total protein, creatinine, bilirubin, AST and ALT). All the haematological parameters measured were significantly (P˂0.05) different among the treatments. Total protein, bilirubin and creatinine values were not significantly (P˃0.05) influenced by DWMOP, however, glucose level and activities of ALP and AST were significantly (P˂0.05) affected by DWMOP. It was concluded that inclusion of DWMOP at 20 % in the diet of rabbits does not have any deleterious effect on the health status of the animal.
Extraction Equilibrium of Dicarboxylic Acids with Tertiary Amine in Single and Binary Diluents

Abstract The extraction equilibria of aliphatic dicarboxylic acids with solutions of trialkylamine (TAA) in binary diluents were measured and compared. Oxalic, succinic, DL‐malic and D‐tartaric acids were used. Trialkylamine with C7–C9 carbon atom chains was dissolved in 1‐octanol, methyl‐isobutyl ketone (MIBK), and chloroform, or in their binary mixtures with n‐heptane. Physical extraction with pure active diluents also was measured. The contribution of physical extraction was significant only in the case of succinic and oxalic acids and with octanol‐1 and MIBK as diluents. In all systems, formation of the (1:1) acid:amine complex was found dominant at low aqueous‐phase equilibrium acid concentrations. The values of the respective equilibrium constants grew in the same order as the first dissociation constants of these acids. In the region of high acid concentrations, overloading of amine was observed, indicating formation of (2:1) and (3:1) complexes. Here, the extraction grew with increasing lyophilicity of the acids. Various modifications of a mathematical model, incorporating reactions of formation of these complexes and physical extraction, were used for correlating the equilibrium data.
Safety of subxiphoid uniportal video-assisted thoracoscopic surgery for anterior mediastinal tumour in obese patients

Introduction Subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) has been gradually applied for the treatment of anterior mediastinal tumour (AMT). However, whether obesity is a risk factor for subxiphoid uniportal VATS for AMT is still unknown. Aim To explore the safety and short-term outcome of subxiphoid uniportal VATS for AMT in obese patients. Material and methods The clinical data of 142 patients who received VATS via subxiphoid approach for AMT were analysed. According to body mass index (BMI), the patients were divided into an obese group (BMI ≥ 28 kg/m2) and a non-obese group (BMI < 28 kg/m2). Then, the clinical and surgical characteristics between the obese group and the non-obese group were analysed to explore the effect of obesity on VATS for AMT. The pain scores were evaluated by the Numeric Rating Scale. Results The operative time and tracheal intubation time using subxiphoid uniportal VATS for AMT in the obese group were longer than that in the non-obese group (p < 0.05). However, there was no obvious difference in intraoperative blood loss, chest tube drainage time, chest tube drainage volume, and length of hospital stay between the obese group and the non-obese group (p > 0.05). Moreover, there was also no significant difference in postoperative complications, including pulmonary complications, wound infection, arrhythmia, and pulmonary leak, between the obese group and the non-obese group. In addition, the pain scores in the obese group were similar to those in the non-obese group. Conclusions Although obesity might prolong operative time of subxiphoid uniportal VAST for AMT, it does not increase the rate of postoperative complications. An experienced centre can properly conduct VAST via subxiphoid approach when treating AMT in obese patients.
Estimated Sleep Duration Before and During the COVID-19 Pandemic in Major Metropolitan Areas on Different Continents: Observational Study of Smartphone App Data

Background Amid the COVID-19 pandemic, public health policies to curb the spread of SARS-CoV-2 and its associated disease, COVID-19, have resulted in significant alterations to daily routines (eg, work-from-home policies) that may have enabled longer sleep duration among the general population. Objective We aimed to examine changes in estimated sleep duration in 5 major metropolitan areas before and after the start of the COVID-19 pandemic. Methods We conducted a prospective observational study using estimated sleep duration data obtained from a smartphone app. The data were obtained from regular users of the smartphone app before and after the World Health Organization declared COVID-19 a pandemic in March 2020. We compared within-subject estimated sleep duration before and during the COVID-19 pandemic using generalized linear mixed models. Results Among the 2,871,037 observations, 957,022 (33.3%) were from users in London; 549,151 (19.1%) were from users in Los Angeles; 846,527 (29.5%) were from users in New York City; 251,113 (8.7%) were from users in Seoul; and 267,224 (9.3%) were from users in Stockholm. The average age of the users in the sample was 35 years (SE 11 years). Prior to the COVID-19 pandemic, people residing in Seoul had the shortest estimated sleep duration (mean 6 hours 28 minutes, SE 11.6 minutes) and those residing in Stockholm had the longest estimated sleep duration (mean 7 hours 34 minutes, SE 9.9 minutes). The onset of the COVID-19 pandemic was associated with a 13.7 minute increase in estimated sleep duration when comparing March 2019 and March 2020 (95% CI 13.1-14.3, P<.001) and an increase of 22.3 minutes when comparing April 2019 and April 2020 (95% CI 21.5-23.1, P<.001). Conclusions The average estimated sleep duration increased sharply in the months after the onset of the COVID-19 pandemic. This finding suggests that the implementation of COVID-19 mitigation strategies has provided people worldwide with increased opportunities to sleep, which may enhance the response of the immune system to viral pathogens.
Comparison and Interpretation of Characteristics of Rhizosphere Microbial Communities in Three Blueberry Varieties

Background: Studies on the rhizosphere microbiome of various plants proved that rhizosphere microbiota carries out various vital functions and can regulate the growth and improve the yield of plants. However, the rhizosphere microbiome of commercial blueberry was only reported by a few studies and remains elusive. Comparison and interpretation of the characteristics of the rhizosphere microbiome of blueberry are critical important to maintain its health. Results: In this study, a total of 20 rhizosphere soil samples, including 15 rhizosphere soil samples from three different blueberry varieties and five bulk soil samples, were sequenced with a high-throughput sequencing strategy. Based on these sequencing datasets, we profiled the taxonomical, functional, and phenotypic compositions of rhizosphere microbial communities for three different blueberry varieties and compared our results with a previous study focused on the rhizosphere microbiome of blueberry varieties. Our results demonstrated significant differences in alpha diversity and beta diversity of rhizosphere microbial communities of different blueberry varieties and bulk soil. The distribution patterns of taxonomical, functional, and phenotypic compositions of rhizosphere microbiome differ across the blueberry varieties. The rhizosphere microbial communities of three different blueberry varieties could be distinctly separated, and 28 discriminative biomarkers were selected to distinguish these three blueberry varieties. Core rhizosphere microbiota for blueberry was identified, and it contained 201 OTUs, which were mainly affiliated with Proteobacteria, Actinobacteria, and Acidobacteria. Moreover, the interactions between OTUs of blueberry rhizosphere microbial communities were explored by a co-occurrence network of OTUs from an ecological perspective. Conclusions: This pilot study explored the characteristics of blueberry’s rhizosphere microbial community, such as the beneficial microorganisms and core microbiome, and provided an integrative perspective on blueberry’s rhizosphere microbiome, which beneficial to blueberry health and production.
Tumors of Craniofacial Region in Iraq (Clinicopathological Study)

Craniofacial tumors are a heterogeneous pathologic disorder with various clinical behaviors and histopathological presentation. Due to their special location, these neoplasms affect speaking and swallowing that may result in movement of teeth, bony expansion and involvement of adjacent craniofacial structures and destruction. This study aims to conduct a clinicopathological study of the management of the craniofacial tumors among patients in Iraq. A total of 319 patients, including 157 (≈49%) males and 162 (≈51%) females, enrolled in the study were attending the Ramadi Teaching Hospital, Zuhur Private Hospital, Razi Private Hospital and Rashid Private Hospital for diagnosis and treatment. Of the total collected samples, 75 (23%) were in the age group of 3140 years, 168 (54%) were presented as mass, 102 (32%) were treated by surgical excision and 51 (16%) were treated by laser surgery. Many cystic and neoplastic pathosis (weather benign or malignant) are unique in craniofacial region due to aesthetic defect and functional impairment which revealed variations in geographical prevalence as well as pattern due to occupational, sociocultural, and climatic factors.
Synergistic solvent extraction of trivalent lanthanides with mixtures of 3-phenyl-4-benzoyl-5-isoxazolone and crown ethers

ABSTRACT Synergistic solvent extraction of trivalent lanthanides such as Nd, Eu and Tm has been studied using mixtures of 3-phenyl-4-benzoyl-5-isoxazolone (HPBI) and 18-crown-6; 15-crown-5, benzo-15-crown-5, or dibenzo-18-crown-6. The results demonstrate that these trivalent metal ions are extracted into chloroform as Ln(PBI)3 with HPBI alone and as Ln(PBI) 3. CE in the presence of crown ethers (CE). The equilibrium constants of the above species are found to increase monotonically with the decreasing ionic radii of these trivalent lanthanides. The addition of a crown ether to the metal chelate system significantly enhances the extractability of these trivalent metal ions.
Cross-Cultural Differences in Online Corporate Communication About Diversity A Comparison of Companies From 15 Countries on the Way How They Communicate About the Workforce Diversity on Corporate Websites

A globalization of the modern world and demographic shifts in the society have led to a growing interest of organizations in the topic of workforce diversity. Research in the fields of management and corporate social responsibility (CSR) reveals that managing diversity at the workplace has the potential implications for organizational outcomes, depending on how companies approach it. At the same time, organizations worldwide have started to communicate about diversity issues on their corporate websites, making implicit their motives to tackle workforce diversity. Yet, little to no advancements have been made in terms of researching cross-country differences in the way organizations address and approach the topic of workforce diversity and the role of a national culture in shaping the latter. Applying a theoretical framework provided by Thomas and Ely (2001), the study compares companies from 15 countries with the biggest economies in the world regarding the way they report on workforce diversity on their corporate websites. Countries are compared based on their cultural set of values, defined by Hofstede (2001) as level of individualism. The paper employs quantitative content analysis as a research method and analyses 150 corporate websites by evidence of workforce diversity communication, type of diversity addressed, and diversity management perspective applied by a company. The study contributes to the underdeveloped literature on the topic of online workforce diversity communication by revealing cultural patterns in organizational reporting on the topic. It is then revealed that the level of individualism in the country positively correlates to evidence of online diversity promotion. Moreover, even though for most of types of diversity reported the association with individualism scores was not identified, the analysis showed significance for promoting equal rights for people with any gender identity and sexual orientation, and for those with different educational and professional backgrounds. Finally, there is a significant relationship between diversity perspectives applied by a company and level of individualism in the country.
Exploring the effects of pre-task planning time on EFL learners’ narrative writing

El present estudi es va dur a terme amb la finalitat de proporcionar informacio sobre els efectes del temps de planificacio previa a la tasca en l’escriptura narrativa d’aprenents d’angles com a llengua estrangera iranians (precisio, fluidesa i complexitat). Amb aquest objectiu, 70 estudiants de tres classes d’instituts d’idiomes privats a l’Iran van ser assignats a l’atzar a grups sense temps de planificacio, amb 5 minuts de planificacio o amb 10 minuts de planificacio. L’analisi de les narratives escrites i els resultats de les analisis ANOVA unidireccionals van revelar que els grups que van tenir 5 o 10 minuts de planificacio previa a la tasca van mostrar un progres substancial en comparacio amb el grup sense temps de planificacio quant a la precisio, fluidesa i complexitat de la seva produccio. Els resultats obtinguts suggereixen que proporcionar oportunitats de planificacio previa a la tasca resulta en millor complexitat, precisio i fluidesa. Els resultats tambe tenen algunes implicacions per al professorat.
