The H.E.S.S. Standard Analysis Technique

The High Energy Stereoscopic System (H.E.S.S) is an array of four imaging atmospheric-Cherenkov telescopes located in Namibia. With the ability to detect a 1% Crab Nebula flux source in ∼25 hours of observation, H.E. S.S. is currently the most sensitive detector of astrophysical VHE (>100 GeV) photons. The H.E. S.S. collaboration has published the detection of more than 30 sources of VHE γ-ray emission. The standard analysis technique used in these publications for reconstructing the direction and energy of incident γ-rays, rejecting the large cosmic-ray background, and determining the spectrum and flux of the detected sources is presented.
Combined Internal Iliac Artery Ligation, Transverse B-Lynch Suture and Intrauterine Balloon to Control Bleeding from Placenta Accreta during Caesarean Delivery

Introduction and aim: Placenta praevia and accreta are associated with high morbidity and mortality. Bleeding is the sole etiology of both morbidity and mortality. Thus, anti-bleeding measures are mandatory and research continues to search for ideal prophylactic measure. This work was designed to assess the efficacy of bilateral internal iliac artery ligation followed by Transverse B-Lynch compression suturing and intrauterine balloon tamponade as a conservative methods to control placental site bleeding due to placenta praevia accreta. Methodology: The study included 24 pregnant females with placenta praevia accreta who were scheduled for elective cesarean section. All participants were subject to history taking, clinical evaluation and laboratory investigations. Ultrasound examination was carried out for assessment of: Estimated fetal weight, confirmation of gestational age, confirm diagnosis of placenta previa accreta and level of the placental edge in lower uterine segment. Deliveries were scheduled to take place between 36-37 weeks of gestation. The primary outcome was the amount of intra-operative blood loss. Results: Blood loss ranged between 249.29 and 560.43 ml, and there was statistically significant decrease of hematocrit percent and platelets after surgery when compared to corresponding values before surgery. All females need blood transfusion. However, none of them need further surgical intervention or intensive care unit admission. Conclusion: Prophylactic bilateral internal iliac artery ligations before extraction of placenta accreta followed by transverse B Lynch suture and intrauterine balloon tamponade seemed to be an effective and safe technique to reduce intrapartum and postpartum complications, and to avoid emergent peripartum hysterectomy.
Scheduling of Coupled Train Platoons for Metro Networks: A Passenger Demand-Oriented Approach

In recent years the concept of virtual coupling, where multiple train units are virtually coupled into a platoon with very short following distances, has received considerable attention in the railway transportation field. This study introduces this concept into the train scheduling problem to improve line capacity and reduce congestion in urban metro networks. With consideration of the time-dependent passenger demand, train (platoon) loading capacity, and limited rolling stock resources, specifically, a mixed integer linear programming model is developed to simultaneously generate the platoon (de)coupling strategies, orders of trains, and their arrival/departure times at each station in the metro network. Several model improvement strategies, for example, model linearization and determination of big- M values, are proposed to enhance the computational efficiency of the model. Finally, numerical experiments based on historical passenger data from the Beijing metro network are implemented to verify the effectiveness of the approach. The results demonstrate that the introduction of train platoons of different sizes can evidently reduce station congestion, while the percentage improvement greatly depends on the distribution of passenger demand.
Proactivity and Job Search: The Mediating Role of Psychological Closeness With External Mentors

Building on contest and sponsored-mobility perspectives, we explain how proactivity enables individuals to develop external mentoring support. By becoming psychologically close with external mentors, we predict that protégés engage in greater job search as additional job opportunities become visible. Results of two studies from different data sources (MTurk and Prolific Academic) support a connection between external mentoring and job search. Moreover, our first study suggests that gender alters the conditional indirect effect of psychological closeness with external mentors, such that women compared to men, who may have a smaller pool of internal mentors to connect with, initiate and benefit more from the influence of external mentors. In our second study, we find partial support for mediation from proactivity to job search self-efficacy (but not job search behavior) through psychological closeness with external mentors, but no gender effect. We urge career counselors to encourage individuals to consider diversifying mentoring outside of organizations.
Molecular detection of human herpes virus 7 in women patients with recurrent pregnancy loss

Viral infections during pregnancy have been associated with adverse pregnancy outcomes and birth defects in the offspring. Viruses rarely cross the placental barrier, but when the virus does reach the fetus, it can result in severe birth defects such as microcephaly or even fetal death. Human herpes virus 7 (HHV-7) is thought to cause severe complications is spontaneous abortion. These experiments were conducted to study the effect of human herpes virus -7 on the pregnant women and cause abortion. This case control study was done for 100 patients including different ages that range from 18-47 age that sever recurrent miscarriage. Also the study includes 50 apparently healthy control (AHC) this age were similar with the patients age. The specimens were collected during winter from August 2021 to February 2022. Endometrium; Cervical swabs; fetal fluids swabs as well as Blood specimens were collected and processed to extract viral genome. The mean age of the patients with RPL was (‎32.70±12.41 years) was less than the mean age of the AHC (30.67 ± 11.17 years). There are non-significant statistical differences (p=0.47) between RPL and AHC.
Seroepidemiology of Hydatid Cyst in Outpatients Attending Health Centers in Arak City, Iran, 2020

Background and Objective: Hydatidosis is one of the most important zoonotic infections that is a health-economic concern in endemic areas. This study aimed to determine the seroprevalence of hydatidosis in Arak, Iran. Materials and Methods: This descriptive cross-sectional study was conducted on 456 individuals attending health centers in Arak in 2020. Blood samples were taken from the subjects and tested for anti-Echinococcus antibodies by the enzyme-linked immunosorbent assay-immunoglobulin G test. The collected data were then analyzed. Results: It was revealed that 6 out of 456 subjects had anti- Echinococcus antibodies (1.3%, 95% confidence interval: 0.3-2.3) The mean age of the participants was 58.8±19.9 years, and frequencies of seropositive individuals were 1.6% and 1% in men and women, respectively. Moreover, 5 (1.4%) and 1 (1%) urban and rural residents were found seropositive, respectively. According to the results, 93.4% of the participants were unaware of hydatid cyst disease and 21.5% of the cases had contact with dogs (P<0.05). It was found that 213 (46.7%) individuals used only water or saltwater to wash vegetables, and all seropositive subjects were observed in this group (P=0.01). Conclusion: The results of this study showed that the seroprevalence of hydatidosis was significant in Arak. Therefore, due to the health importance of hydatidosis and its endemicity in this area, it is necessary to adopt health measures to control and prevent this parasitic infection.
Tailored ZnO Functional Nanomaterials for Solution‐Processed Quantum‐Dot Light‐Emitting Diodes

Recent improvements in efficiency and luminance of quantum‐dot light‐emitting diodes (QLEDs) promise a versatile technology for next‐generation lighting and display applications. This is accomplished due to the advances in colloidal quantum‐dot (CQD) synthetic methods together with proper engineering of the charge balance in these devices. The exciton quenching mechanisms occurring at the interface between the QD emissive layer and the zinc oxide (ZnO) electron transport layer (ETL) are one of the important parts of the charge transport path, affecting efficiency and long‐term stability. Herein, a comprehensive overview of the advances in the engineering of ZnO‐based ETLs, in terms of device efficiency and operational stability, is attempted. It is specifically highlighted that significant improvements can be achieved using various ZnO ETL defect passivation methods. This review also describes the key requirements for high‐performance QLEDs from the ETL engineering aspect and catalyzes for further interdisciplinary explorations to realize reliable devices for practical applications.
Academic Writing Difficulties Encountered by University EFL Learners

The present study was conducted with the aim to discover the major difficulties encountered by some university students in academic writing. It also aimed to find out the factors that hinder their academic writing skills. 36 students majoring in English at the Faculty of Education, University of Benghazi took part in this study. A questionnaire with 25 items was utilized to answer the stated research questions. The data analysis revealed that both graduate and undergraduate students have some problems in academic writing such as choosing the appropriate academic words, difficulty in developing a thesis statement, organizing ideas, and writing coherent paragraphs. These challenges were influenced by a lack of resources followed by a low English language proficiency and a lack of writing practice opportunities. It is hoped that the findings of this research would provide great benefits to the instructors of the English language and curriculum designers to address the writing difficulties that might be encountered by learners of English.

Rotifer Communities (Rotifera: Eurotatoria) of Rice-Field Ecosystems of Meghalaya: Composition and Distribution

Rice fields exhibit a rich mosaic of ecotones, changing in time and space seasonally and rapidly and are characterized by complex limnology not mirrored by any natural aquatic habitat (Fernando, 1995), In addition, they combine unique features of aquatic and semi-aquatic environs during different growth phases of paddy cultivation and are known to be biologically diverse biotopes colonized by a wide spectrum of aquatic organisms (Fernando et al., 1979; Fernando, 1993) in general and micro-invertebrate communities in particular. The later, in turn, are invariably characterized by greater rotifer richness.
The role of immunotherapy plus chemotherapy versus chemotherapy alone as first-line treatment for advanced non-small cell lung cancer: an updated systematic review and meta-analysis of randomized controlled trials

ABSTRACT Background Recently published randomized controlled trials (RCTs) showed improved overall survival (OS) and progression-free survival (PFS) with the combination of immunotherapy and chemotherapy as compared to chemotherapy alone in advanced non-small cell lung cancer (NSCLC). We aimed to provide a systematic review and meta-analysis of RCTs regarding the efficacy and safety of immunotherapy and chemotherapy combinations for advanced NSCLC. Methods On December 23rd, 2021, we searched databases for RCTs that reported PFS and OS as primary outcomes. Results We included 11 RCTs with 6,386 patients (3,850 in the combination therapy group and 2,536 in the chemotherapy group). Combination therapy was associated with an improvement in PFS (HR: 0.60; 95% CI: 0.54, 0.66; P < 0.00001) andOS (HR: 0.77; 95% CI: 0.68, 0.87; P ≤ 0.0001), compared to chemotherapy. There were no significant differences between both groups in terms of treatment-related adverse events (TRAEs) (RR: 1.07; 95% CI: 0.99, 1.16; P = 0.09). Conclusion The combination of immunotherapy and chemotherapy as first-line treatment for advanced NSCLC significantly improved PFS and OS compared to chemotherapy alone without a significant increase in the overall TRAEs.
Lymphoma-associated hemophagocytic syndrome: a retrospective study from a single center

ABSTRACT Lymphoma-associated hemophagocytic syndrome (LAHS) is a rare and life-threatening clinical syndrome with rapidly deteriorating health and high mortality. We retrospectively analyzed clinical features and prognostic factors from 117 patients diagnosed with LAHS. The cumulative incidence rate of LAHS was 4.0% (117/2906). Patients were classified into B-cell LAHS (B-LAHS, n = 22) and T/natural killer (NK)-cell LAHS (T/NK-LAHS, n = 95) groups. Patients with T/NK-LAHS were younger and had lower neutrophil counts and fibrinogen values, higher LDH and transaminase levels, and were more likely to develop hemophagocytic syndrome (HPS) during the clinical course than those with B-LAHS. The median survival time for the entire cohort was 57 days, and for the T/NK-LAHS and B-LAHS groups, it was 52 and 154 days, respectively, after the diagnosis of LAHS. Patients with B-LAHS had superior 1-year OS (p = 0.003, 36.4% versus 14.5%) compared with those with T/NK-LAHS. Prognostic factor analysis revealed that elevated LDH levels (LDH > 1000 IU/L) (p = 0.004), T/NK-cell lineage (p < 0.001) and HPS onset at relapse (p = 0.001) were strongly associated with early death. For patients diagnosed with T/NK-LAHS, in addition to LDH levels and HPS onset status, high EBV-DNA copies (≥4,450 copies/mL) (p = 0.016) were also related to poor prognosis of T/NK-LAHS.
Association Between Maxillary Impacted Canine Position and Root Resorption of the Adjacent Incisors: A CT Study

Resorption of permanent maxillary incisors is a common complication of ectopically positioned maxillary canines and when they occur they may drastically increasing both the cost and complexity of the orthodontic treatment, thus early diagnosis and corrective measures are imperative. This study aimed to investigate the association between the maxillary impacted canines labio-palatal and mesio-distal positions and the associated root resorption of adjacent maxillary incisors. Materials and Methods: The sample included 46 patients with an age ranged between 12 and 30 years referred to the CT scan image to detect unilaterally or bilaterally impacted maxillary canines. The mesio-distal position of the canine cusp tip, the labio-palatal position of the impacted canines, contact and root resorption of permanent incisors were evaluated with CT scan image. The association between the impacted canines position and root resorption of permanent incisors were analyzed using Chi square test.Results: Labially and mid-alveolus impacted canines were more common in sectors I and IV, while palatally impacted canines were most frequent in Sector IV. Lateral incisors were more often affected than central incisors by root resorption. Root resorption of permanent incisors showed a high significant association with sector location [p ≤ 0.001] and was observed in sectors III and IV.Conclusions: When canine impactions are suspected in sectors III or IV, CT scan must be considered to disclose suspected incisor resorption.
Rewilding—The farmers’ perspective. Perceptions and attitudinal support for rewilding among the English farming community

1. Rewilding is an increasingly common conservation approach, aiming to restore ecosystem processes and minimise human intervention. Rewilding has the potential to profoundly change landscapes and people– nature relations. These issues prompt an ongoing debate about how and if rewilding should be done. 2. Farmers are key stakeholders in this debate; they stand to be both affected by and influence the trajectory of rewilding initiatives developing in the United Kingdom and globally. Despite this
Using simulation modelling and systems science to help contain COVID‐19: A systematic review

Abstract This study systematically reviews applications of three simulation approaches, that is, system dynamics model (SDM), agent‐based model (ABM) and discrete event simulation (DES), and their hybrids in COVID‐19 research and identifies theoretical and application innovations in public health. Among the 372 eligible papers, 72 focused on COVID‐19 transmission dynamics, 204 evaluated both pharmaceutical and non‐pharmaceutical interventions, 29 focused on the prediction of the pandemic and 67 investigated the impacts of COVID‐19. ABM was used in 275 papers, followed by 54 SDM papers, 32 DES papers and 11 hybrid model papers. Evaluation and design of intervention scenarios are the most widely addressed area accounting for 55% of the four main categories, that is, the transmission of COVID‐19, prediction of the pandemic, evaluation and design of intervention scenarios and societal impact assessment. The complexities in impact evaluation and intervention design demand hybrid simulation models that can simultaneously capture micro and macro aspects of the socio‐economic systems involved.
Studies on Physico-chemical and Sensory Characteristics of Whey Based Watermelon Beverage

Whey Based Watermelon Beverage (WBWB) prepared by bending watermelon juice (15%), sugar (7%) and different concentration of Betel leaves distillate (0, 1, 2, 3%) into chhanna whey (78–75%). The prepared beverage has red colour, highly acceptable taste and overall acceptability. The overall acceptability of beverage improved with increase in betel leaves distillate up-to 2%. After in-bottle sterilization and cooling, the beverage was stored at refrigerated temperature. The storage study showed that there is an increasing trend in the TSS, acidity, and reducing sugar and a decreasing trend in the pH and ascorbic acid but total sugar has non significant effect during storage. The sensory quality of fresh beverage containing 2% betel leaves distillate on the preparation as well as 30 days of storage were found to be highly acceptable. Additions of 3% betel leaves distillate do not improve the mouth-feel but they extend the storage period of the product. This indicates that antimicrobial and anti-oxidant properties in essential oil of betel leaf increase the storage stability of the beverage.
Uniqueness and Fréchet differentiability of functional solutions to maximum likelihood type equations

Solutions of simultaneous equations of the maximum likelihood type or M-estimators can be represented as functionals. Existence and uniqueness of a root in a local region of the parameter space are proved under conditions that are easy to check. If only one root of the equation exists, the resulting statistical functional is Frechet differentiable and robust. When several solutions exists, conditions on the loss criterion used to select the root for the statistic ensure Frechet differentiability. An interesting example of a Frechet differentiable functional is the solution of the maximum likelihood equations for location and scale parameters in a Cauchy distribution. The estimator is robust and asymptotically efficient.
Teachers' Experiences in the Implementation of Mother Tongue-Based Multilingual Education in Indigenous People Learner Dominated School in Southern Palawan, Philippines

This study sought to examine the implementation of MTB-MLE in schools where the majority of the students are indigenous learners. It specifically aimed to describe the (1) teachers' experiences with MTB-MLE implementation and the (2) the teachers' concerns in implementation. Purposive sampling was used; 6 Primary Teachers were interviewed using a semi-structured interview technique. Results show that the teachers believe in the program's purpose of the program, but in practice, it has some issues that call for reflection among policymakers and program implementers. The teachers see MTB-MLE as something irrelevant because it is a duplication of the Filipino subject which is not the Mother Tongue of the learners in the first place. Another issue that was revealed is the implication of having a multilingual classroom. The diversity of the linguistic backgrounds of the learners poses a problem. Teacher says that they receive training on MTB-MLE, but such training has no practical relevance to their day-to-day instruction. The teachers also mention the dearth of teaching and learning materials. It could be safely said that the implementation of MTB-MLE failed to achieve its purpose, and it needs more re-thinking. The researchers believe in the goal of Deped in implementing the program but that more research is needed. Collaborating with teachers, anthropologists, linguists, and artists is necessary.
Constraining pterosaur launch: range of motion in the pectoral and pelvic girdles of a medium-sized ornithocheiraean pterosaur

Launch is the most energetically expensive part of flight and is considered a limiting factor in the size of modern flyers. Pterosaurs reached significantly larger sizes than modern flyers and are proposed to have launched either bipedallly or quadrupedally. We investigated the ability of a medium-sized ornithocheiraean pterosaur to assume the poses required to launch bipedally or quadrupedally. We applied range of motion (ROM) mapping methodology to the pectoral and pelvic girdles to identify viable poses at varying levels of appendicular cartilage based on the extant phylogenetic bracket. The ROMs were constrained by novel triangulated minimum stretch methodology, used to identify the restraining tissue ROM. Our study indicates that a medium-sized ornithocheiraean could assume the poses required to use a quadrupedal launch and, with an additional 10° of hindlimb abduction, a bipedal launch, although further analysis is required to determine whether sufficient muscular power and leverage was available to propel the animal into the air.
