Abstract
The Jalpatagua fault in Guatemala accommodates dextral movement of the Central America forearc. We present new global positioning system (GPS) data, minor fault analysis, geochronological analyses, and analysis of lineaments to characterize deformation along the fault and near its terminations. Our data indicate that the Jalpatagua fault terminates at both ends into extensional regions. The western termination occurs near the Amatitlan caldera and the southern extension of the Guatemala City graben, as no through-going structures were observed to continue west into the active volcanic arc. Along the Jalpatagua fault, new and updated GPS site velocities are consistent with a slip rate of 7.1 ± 1.8 mm yr−1. Minor faulting along the central section of the fault includes: (1) N-S–striking normal faults accommodating E-W elongation; and (2) four sets of strike-slip faults (oriented 330°, 020°, 055°, and 295°, parallel to the Jalpatagua fault trace). Minor fault arrays support dextral movement along a major fault in the orientation of the Jalpatagua fault. GPS and fault data indicate that the Jalpatagua fault terminates to the east near the Guatemala–El Salvador border. Data delineate a pull-apart basin southeast of the fault termination, which is undergoing transtension as the Jalpatagua fault transitions into the El Salvador fault system to the east. Within the basin, minor faulting and lineations trend to the NW and accommodate NE-directed elongation. This faulting differs from E-W elongation observed along the Jalpatagua fault and is more similar to minor faults within the El Salvador fault system.

AbstractWe present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross sections for fixed-target neutrino–nucleus deep-inelastic scattering, and cross sections for inclusive gauge-boson production andW-boson production in association with light jets or charm quarks at hadron colliders. Our analysis is accurate to next-to-next-to-leading order in perturbative QCD where available, and specifically includes charm-quark mass corrections to neutrino–nucleus structure functions. We find that a good overall description of the input dataset can be achieved and that a strangeness moderately suppressed in comparison to the rest of the light sea quarks is strongly favored by the global analysis.
Effect of high bandgap AlAs quantum barrier on electronic and optical properties of In0.70Ga0.30As/Al0.60In0.40As superlattice under applied electric field for laser and detector applications
Authors: Alaydin B. O. 
Published: December 2020

Effect of high bandgap [Formula: see text] nm AlAs on the electronic and optical properties of the [Formula: see text]/[Formula: see text] superlattice is investigated by using effective mass approximation under the electric field. Electronic transitions are obtained as 0.403 eV and 0.023 eV for [Formula: see text] and [Formula: see text] in the gain region. Thin AlAs increases electron confinement in the superlattice and prevents electron leakage in the gain region which mostly results in higher absorption/emission in the superlattice. AlAs has no major effects on transitions energies in the gain region but it is effectively decreasing the total absorption in the injector region and preventing the internal absorption. AlAs also makes the superlattice optically more stable by decreasing the high refractive index change in the injector region by factor 5.

Purpose. This study investigated how a conscious change in ocular accommodation affects intraocular pressure (IOP) and ocular biometrics in healthy adult volunteers of different ages. Methods. Thirty-five healthy volunteers without ocular disease or past ocular surgery, and with refractive error between −3.50 and +2.50 diopters, were stratified into 20, 40, and 60 year old (y.o.) age groups. Baseline measurements of central cornea thickness, anterior chamber depth, anterior chamber angle, cornea diameter, pupil size, and ciliary muscle thickness were made by autorefraction and optical coherence tomography (OCT), while IOP was measured by pneumotonometry. Each subject’s right eye focused on a target 40 cm away. Three different tests were performed in random order: (1) 10 minutes of nonaccommodation (gazing at the target through lenses that allowed clear vision without accommodating), (2) 10 minutes of accommodation (addition of a minus 3 diopter lens), and (3) 10 minutes of alternating between accommodation and nonaccommodation (1-minute intervals). IOP was measured immediately after each test. A 20-minute rest period was provided between tests. Data from 31 subjects were included in the study. ANOVA and paired t-tests were used for statistical analyses. Results. Following alternating accommodation, IOP decreased by 0.7 mmHg in the right eye when all age groups were combined (

p

= 0.029). Accommodation or nonaccommodation alone did not decrease IOP. Compared to the 20 y.o. group, the 60 y.o. group had a thicker ciliary muscle within 75 μm of the scleral spur, a thinner ciliary muscle at 125–300 μm from the scleral spur, narrower anterior chamber angles, shallower anterior chambers, and smaller pupils during accommodation and nonaccommodation (

p

’s < 0.01). Conclusion. Alternating accommodation, but not constant accommodation, significantly decreased IOP. This effect was not lost with aging despite physical changes to the aging eye. A greater accommodative workload and/or longer test period may improve the effect.

O enxame de diques máficos de Peixoto de Azevedo e Nova Guarita, região Leste da Província Aurífera Alta Floresta (PAAF), compõe-se de basaltos toleíticos evoluídos. Tais rochas provêm de fonte enriquecida por fluidos originados durante a subducção de crosta oceânica recoberta por significativa quantidade de sedimentos de composição semelhante à média global de sedimentos subductados (global subducting sediment composition — GLOSS). O enxame de diques intrude granitos e gnaisses paleoproterozoicos dos arcos magmáticos Cuiú-Cuiú e Juruena, e possui idade de 1419 Ma. No Cráton Amazônico, suas características geoquímicas relacionadas à sua origem mantélica são muito semelhantes às dos diques máficos de Carajás e da Suíte Máfica Vespor, ambos paleoproterozoicos. São semelhantes em idade quando comparados aos diques de Nova Lacerda, assim como de outras regiões do Supercontinente Columbia, como os diques Bas Drâa Inlier, a W do Cráton da África, a soleira Midsommerso, a NE da Groenlândia, e os diques Michael Gabbro, na Província Grenville, no Canadá. Essas intrusões ocorreram entre 1,42 e 1,33 Ga, durante as fases finais de fragmentação do Supercontinente Columbia.

Background
Specific plaque phenotypes that predict a favorable response to statin therapy have not been systematically studied. This study aimed to identify optical coherence tomography predictors for a favorable vascular response to statin therapy.

Methods and Results

Patients who had serial optical coherence tomography imaging at baseline and at 6 months were included. Thin‐cap area (defined as an area with fibrous cap thickness <200 μm) was measured using a 3‐dimensional computer‐aided algorithm, and changes in the thin‐cap area at 6 months were calculated. A favorable vascular response was defined as the highest tertile in the degree of reduction of the thin‐cap area. Macrophage index was defined as the product of the average macrophage arc and length of the lesion with macrophage infiltration. Layered plaque was defined as a plaque with 1 or more layers of different optical density. In 84 patients, 140 nonculprit lipid plaques were identified. In
multivariable
analysis, baseline thin‐cap area (odds ratio [OR] 1.442; 95% CI, 1.024–2.031,
P
=0.036), macrophage index (OR, 1.031; 95% CI, 1.002–1.061,
P
=0.036), and layered plaque (OR, 2.767; 95% CI, 1.024–7.479,
P
=0.045) were identified as the significant predictors for a favorable vascular response. Favorable vascular response was associated with a decrease in the macrophage index.

Conclusions
Three optical coherence tomography predictors for a favorable vascular response to statin therapy have been identified: large thin‐cap area, high macrophage index, and layered plaque. Favorable vascular response to statin was correlated with signs of decreased inflammation.

Analysis on the Supply Willingness of Mortgage Loan of Farmland Management Right under the Government-Led Mode in China Western’s Region
Authors: Niu Rong , Yan Xiao 
Published: December 2020

Abstract
In this paper, the Probit model was established based on the survey data of 105 loan officers in China’s Western Region, and the factors influencing the willingness of mortgage loan supply of farmland management rights under the government-led model were investigated from the perspective of financial supply. The research shows that farmers’ income, farmers’ policy awareness, farmland scale, loan experience, risk compensation system, legal perfection and policy stability have a positive impact on the willingness of loan officers to issue mortgage loans for farmland management rights. Factors such as farmers’ age and education level have a negative impact on the willingness to supply. In addition, by comparing the stability of the regression model before and after the addition of risk compensation system, legal perfection degree and policy stability degree, it is concluded that the policy variables have a great influence on the decision-making of financial institutions.
“The Main Parts Are Made in Europe”: Apologetic/Critical Dichotomy and the Untold Story of Qur’anic Studies in the Iranian Academy
Authors: Feyzbakhsh Mohsen 
Published: December 2020

Abstract
This response to Majid Daneshgar’s book develops his argument about apologetics in the study of the Qur’an in the Muslim Academy in two ways. First, it makes a distinction between two different senses of the term apologetics and then shows how each sense would be relevant to Daneshgar’s argument. Second, it applies the argument to Islamic studies in the Iranian Academy in particular.
Twenty Years of Triumph, Trial and Tribulation: Reflections on the Mechanism of the African Commission’s Special Rapporteur on the Rights of Women in Africa
Authors: Kariseb Kennedy 
Published: December 2020

Abstract
On the occasion of its 25th Ordinary Session held in Bujumbura, Burundi, from 26 April to 5 May 1999, the African Commission adopted resolution ACHPR/res.38 (XXV) 99 on the appointment of a Special Rapporteur on the Rights of Women in Africa (SRRWA), retrospectively with the appointment taking effect from 31 October 1998. This means that the mechanism of the SRRWA is roughly making twenty years since its initial inception. Coming of age and time, the twenty years of existence of the mechanism of the SRRWA makes it not only one of the oldest (and perhaps most successful) mechanisms of the African Commission; but one that has been the subject of tremendous triumph, trial and tribulation. Over the past two decades, the mechanism has been a product of both progression and regression. By and large the mechanism of the SRRWA has played an appreciable role in the advancement of women’s rights on the African continent. This article aims at taking stock of the achievements and failures of the 20 years of the work of the SRRWA. Although taking pride in the achievements of the mechanism, this article argues for incremental reforms within the mechanism, including the refining of the terms of reference of the mandate; the need for closer cooperation with global and regional systems mechanisms, women at grassroots including women’s rights movements, and mutual support from civil society organisations.
The Interior Frontiers of Germany
Authors: Hernández Aguilar Luis Manuel 
Published: December 2020

Abstract
In 2012, the regional court of the city of Cologne ruled that ritual male circumcision constituted unjustified bodily harm. This prompted a nationwide debate culminating in the enactment of legislation guaranteeing male circumcision without medical justification under certain preconditions. This article proposes to approach the ‘circumcision debate’ as a discursive strand of the systematic problematisation of Muslims as ‘Muslims’, which I analyse through the analytic of the ‘Muslim Question’. In addition, I refer to the concepts of recursive history and of the interior frontier to contextualise the 2012 circumcision debate and the political purpose it has served, namely, to establish racial distinctions and interior frontiers between Germans, Jews and Muslims.

Published: December 2020

Abstract
This study introduces issue concept maps (IC map) as an instructional tool for exploring students’ idea about socio-scientific issues (SSI). By visualizing students’ ideas in two dimensions, context and occurrence, IC maps represent what kinds of ideas students have on the issues, and how their ideas change and connect. In the study, we implemented a SSI program on fine dust for 77 seventh graders and used IC maps to investigate how their ideas changed after the program. Students collaboratively constructed IC maps in groups before and after the program. Results show that the number of ideas written on IC maps significantly increased after the program from 92 to 254 ideas, indicating that the program contributed to enhancing students’ awareness about the issues in terms of its causes, effects, and countermeasures at various context levels. Students also presented a greater variety of types of connections among their ideas after the program.

Published: December 2020

Background The procedures that rural general surgeons perform may be changing. It is important to recognize the trends and practices of the current rural general surgeon in efforts to better prepare general surgeons who desire to enter a practice in a rural environment. The aim of this review is to detail the recent operative case volumes of 6 rural locations in the upper Midwest where general surgery is practiced. Methods The Enterprise Data and Analytics department of Sanford Health compiled all surgical procedures performed within the Sanford Health System between January 1, 2013 and August 31, 2018. Procedures performed by a total of 58 general surgeons in locations of under 50 000 people are included in this review. Results From January 1, 2013 to August 31, 2018, 38 958 surgical procedures were performed in rural locations. Endoscopic procedures made up 61.6% of a rural general surgeon’s practice. Cholecystectomy (6.3%), hernia repair (6.3%), and appendectomy (3.7%) were the principle nonendoscopic procedures performed by rural surgeons, comprising 16.3% of the case volume. Added together, endoscopy, cholecystectomy, hernia repair, and appendectomy made up 77.9% of the rural general surgeon’s caseload. Vascular procedures (2.5%), breast procedures (1.8%), obstetrics (0.4%), and urology procedures (0.2%) are also included in this review. Conclusions Rural general surgeons are vital to the surgical workforce in the United States. Recognizing a trend that rural general surgeons perform less subspecialty procedures and more endoscopic procedures will provide direction for those interested in pursuing a career in rural general surgery.

Published: December 2020

Background Postoperative in-hospital pneumonia is a serious complication. This study aims to investigate the association between 3 preoperative stratification tools (American Society of Anesthesiologists Physical Status [ASA-PS] score, Charlson Comorbidity Index [CCI], and Rockwood Frailty Deficit Index [FI]) and risk for postoperative pneumonia. Methods We identified adult patients who developed postoperative pneumonia following noncardiothoracic surgery under general anesthesia, between January 1, 2016 and December 31, 2017. Patients with postoperative pneumonia were 1:1 matched to control subjects based on age, sex, and the exact type of operations. Medical records were reviewed to identify variables that may be associated with risk for developing postoperative pneumonia. Analyses adjusted for clinical characteristics were performed using the conditional logistic regression, taking into account 1:1 matched set case-control study design. Results We identified 211 cases of postoperative pneumonia, and all 3 tested stratification tools were associated with increased risk: ASA-PS (after all adjustments of American Society of Anesthesiologists (ASA) III, odds ratio 4.17 [95% confidence interval 1.74-10.01]; ASA > III 24.03 [6.54-88.32]), CCI (CCI values > 3, 1.29 [1.02-1.63] per unit CCI score), and frail FI score 3.25 (1.45-7.27). Because of incomplete intake documentation, the FI could not be calculated in 57 (13.5%) patients, but these “unknown frailty” patients were also at increased risk for postoperative pneumonia, 3.15 (1.29-7.72). Discussion Three commonly used stratification indices (ASA-PS score, CCI, and FI) were associated with increased risk for postoperative pneumonia. Patients unable to complete intake form to calculate the FI were also at increased risk.

Published: December 2020

Introduction Surgical intervention is important in reducing morbidity and mortality among patients admitted for small bowel obstruction (SBO). Patient-specific variables such as age and comorbidities are risk factors for adverse outcomes after surgery for SBO. However, the effect of weekend admission on outcomes has not been well delineated in the literature. Our aim was to determine whether weekend admission affects mortality and length of stay (LOS) in patients who were admitted for SBO and were managed operatively. Materials and Methods Using the 2006-2012 Nationwide Inpatient Sample (NIS) database, we identified adult patients who were admitted with a primary diagnosis of SBO and had a primary procedure of exploratory laparotomy, lysis of adhesions, or small bowel resection. We performed univariate analysis comparing cases that were admitted on the weekend vs. weekday. We then performed negative binomial regression with LOS as the dependent variable, adjusting for risk variables. Results 2804 patients were studied, of which 728 (26.0%) were admitted on the weekend. Univariate analysis showed no statistically significant difference in mortality or LOS for patients admitted on a weekday vs. weekend. Multivariate analysis showed that several factors were associated with increased LOS, including third quartile van Walraven score ( P < .0001) and large hospital size ( P = .0031). Other factors were associated with decreased LOS, including fourth quartile of income ( P = .0022) and weekend admission ( P = .048). Discussion There is no significant difference in mortality between patients admitted on weekend vs. weekday for SBO, but patients admitted on weekend are more likely to have a decreased LOS.

Published: December 2020

Background Prompt drainage of traumatic hemothorax is recommended to prevent empyema and trapped lung. Some patients do not present the day of their trauma, leading to their delayed treatment. Delayed drainage could be challenging as clotted blood may not evacuate through a standard chest tube. We hypothesized that such delays would increase the need for surgery or secondary interventions. Methods Our trauma registry was reviewed for patients with a hemothorax admitted to our level 1 trauma center from 1/1/00 to 4/30/19. Patients were included in the delayed group if they received a drainage procedure >24 hours after injury. These patients were matched 1:1 by chest abbreviated injury score to patients who received drainage <24 hours from injury. Results A total of 19 patients with 22 hemothoraces received delayed drainage. All but 3 patients had a chest tube placed as initial treatment. Four patients received surgery, including 3 who initially had chest tubes placed. Longer time to drainage increased the odds of requiring intrathoracic thrombolytics or surgery. In comparison, 2 patients who received prompt drainage received thrombolytics ( P = .11) and none required surgery ( P = .02). Patients needed surgery when initial drainage was on or after post-injury day 5, but pigtail catheter drainage was effective 26 days after injury. Discussion Longer times from injury to intervention are associated with increased likelihood of needing surgery for hemothorax evacuation, but outcomes were not uniform. A larger, multicenter study will be necessary to provide better characterization of treatment outcomes for these patients.
