ObjectivesTo examine physicians’ perceptions of changing employment opportunities in Brazil, and gain an insight into labour markets in low/middle-income countries (LMICs) during the pandemic.Study designDescriptive and inferential analysis of a quantitative dataset from a representative cross-sectional survey of physicians of two Brazilian states.SettingsSão Paulo and Maranhão states in Brazil.ParticipantsRepresentative sample of 1183 physicians.Outcome measuresWe estimated prevalence and 95% CIs for physicians’ perceptions of changes in demand and supply of doctors, as well as changes in prices of medical services for facilities of practice in the two states, stratified by public, private and dual-practice physicians.ResultsMost doctors reported increased job opportunities in the public sector (54.9%, 95% CI 52.0% to 57.7%), particularly in Maranhão state (65.0%, 95% CI 60.9% to 68.9%). For the private sector, increased opportunities were reported only in large private hospitals (46.7%, 95% CI 43.9% to 49.6%) but not in smaller clinics. We recorded perceptions of slight increases in availability of doctors in Maranhão, particularly in the public sector (51.4%, 95% CI 43.2% to 59.5%). Younger doctors recounted increased vacancies in the public sector (64%, 95% CI 58.1% to 68.1%), older doctors only in walk-in clinics in Maranhão (47.5%, 95% CI 39.9% to 55.1%). Those working directly with patients with COVID-19 saw opportunities in public hospitals (65%, 95% CI 62.3% to 68.4%) and in large private ones (55%, 95% CI 51.8% to 59.1%).ConclusionsOur findings hint that health labour markets in LMICs may not necessarily shrink during epidemics, and that impacts will depend on the balance of public and private services in national health systems.

Published: August 2023

BackgroundStrabismus can have a great negative impact on the quality of life and the well-being of affected patients. In the past, these aspects were often neglected and, compared with somatic functioning, placed in the background. The aim of our study is to elicit factors influencing satisfaction with strabismus surgery, quality of life and expectations of surgery in order to better predict who will benefit the most and who may need further support.MethodsWe made a selection of suitable questionnaires to assess psychosocial aspects of strabismus and decided for Adult Strabismus 20 Questionnaire, Amblyopia and Strabismus Questionnaire, Diplopia Questionnaire, Expectations of Strabismus Surgery Questionnaire and Hospital Anxiety and Depression Scale. We then translated these measures (if not available in German). The patients filled out these forms as part of their preoperative orthoptic and ophthalmological assessment as well as approximately 3 months after strabismus surgery.ResultsWe enrolled 59 patients in this study. Postoperative strabismus-related quality of life was higher after surgery and anxiety and depression levels were lower. Satisfaction with surgery was lower with higher postoperative angle and diplopia; the latter was also a determinant of lower postoperative quality of life. Higher expectations of strabismus surgery were present with higher depression levels and higher preoperative strabismus angle.ConclusionOur data indicate that strabismus surgery may cause a significant improvement in several psychosocial domains. There is evidence that psychosocial factors can have significant impact on expectations with surgery. Hence, it is important to consider mental health aspects of this disease in order to treat patients in the best possible way.
Gravitational Larmor precession
Authors: Chakraborty Chandrachur , Majumdar Parthasarathi 
Published: August 2023

AbstractInspired by the reported existence of substantive magnetic fields in the vicinity of the central supermassive black holes in Sagittarius A* and Messier 87*, we consider test particle motion in the spacetime close to a generic spherical black hole in the presence of magnetic fields in its vicinity. Modelling such a spacetime in terms of an axisymmetric, non-rotating Ernst–Melvin–Schwarzschild black hole geometry with appropriate parameters, we compute the geodesic nodal-plane precession frequency for a test particle with mass, for such a spacetime, and obtain a non-vanishing result, surpassing earlier folklore that only axisymmetric spacetimes with rotation (non-vanishing Kerr parameter) can generate such a precession. We call this magnetic field-generated phenomenon Gravitational Larmor Precession. What we present here is a Proof of Concept incipient assay, rather than a detailed analysis of supermassive black holes with magnetic fields in their neighbourhood. However, for completeness, we briefly discuss observational prospects of this precession in terms of available magnetic field strengths close to central black holes in galaxies.
ReSG: A Data Structure for Verification of Majority-based In-memory Computing on ReRAM Crossbars

Published: August 2023

Recent advancements in the fabrication of
Resistive Random Access Memory
(ReRAM) devices have led to the development of large-scale crossbar structures. In-memory computing architectures relying on ReRAM crossbars aim to mitigate the processor-memory bottleneck that exists with current complementary metal-oxide semiconductor technology. With this motivation, several synthesis and mapping approaches focusing on the realizations of Boolean functions in the ReRAM crossbars have been proposed earlier. Thus far, the verification of the designs realized on ReRAM crossbars is done either through manual inspection or using simulation-based approaches. Since manual inspections and simulation-based approaches are limited to smaller designs, they cannot be applied to the verification of complex designs on large-scale ReRAM crossbars.

Motivated by this, we propose, for the first time, an automatic equivalence checking flow that determines the equivalence between the original function specification (e.g.,
Majority-inverter Graph
) and the crossbar micro-operations file formats. We consider two crossbar structures,
zero-transistor, one-memristor (0T1R)
and
one-transistor, one-memristor (1T1R)
to implement the micro-operations. While the micro-operations file format exists for 0T1R crossbar structures, no representations for micro-operations to be executed in 1T1R crossbars exist yet. In this work, we introduce the micro-operation file format for 1T1R crossbar structures to efficiently represent the micro-operations as ReRAM crossbar netlists. Afterwards, we introduce two intermediate data structures,
ReRAM Sequence Graph
for 0T1R crossbars
(ReSG-0T1R)
and for 1T1R crossbars
(ReSG-1T1R)
, that are derived from the 0T1R and 1T1R crossbar micro-operations file formats, respectively. These ReSGs are then translated into
Boolean Satisfiability
(SAT) formula, and then the verification is done by checking the generated SAT formulae against the golden functional specification (represented in Verilog) using
Z3 Satisfiability
solver. Experimental evaluations confirm the effectiveness of the proposed verification methodology on MCNC and ISCAS benchmarks.

Published: August 2023

Abstract

Background:
Given the role of the immune system in non-Hodgkin lymphoma (NHL) etiology, obesity and type 2 diabetes (T2D) may impact NHL development. We examined the association of body mass index (BMI) and T2D with NHL in the multiethnic cohort (MEC).

Methods:
The MEC recruited &gt;215,000 participants in Hawaii and Los Angeles from five racial/ethnic groups; NHL cases were identified through cancer registry linkages. T2D status, and BMI at age 21 and cohort entry were derived from repeated self-reports; for T2D, Medicare claims were also applied. HRs and 95% confidence intervals (CI) for BMI and T2D as predictors of NHL were determined using Cox regression adjusted for relevant covariates.

Results:
Among 192,424 participants, 3,472 (1.8%) with NHL and 68,850 (36%) with T2D after 19.2 ± 6.6 years follow-up, no significant association between T2D and NHL (HR, 1.04; 95% CI, 0.96–1.13) was observed. Stratification by BMI at cohort entry showed a significant association of T2D with NHL among individuals with normal weight only (HR, 1.18; 95% CI, 1.03–1.37). In a model with both BMI values plus T2D, only overweight (HR, 1.13; 95% CI, 1.01–1.26) and obesity (HR, 1.25; 95% CI, 0.99–1.59) at age 21 were associated with NHL incidence. Stratification by sex, race/ethnicity, and NHL subtype indicated no differences.

Conclusions:
Our findings suggest an association between T2D and NHL incidence in several subgroups but not in the total population and an elevated risk related to early-life BMI.

Impact:
Excess body weight in early life, rather than T2D, may be a predictor of NHL incidence.
Faith in Science: Religion and Climate Change Attitudes in the Middle East
Authors: Mazaheri Nimah 
Published: August 2023

Abstract
The Middle East is facing many challenges because of climate change: extreme heat, recurring droughts, water salinization, and more. Yet little is known about how people in the region perceive the threat of climate change or about the factors associated with perceiving it as more or less of a threat. This study utilizes the Arab Barometer surveys and examines how religion influences climate change perceptions among 13,700 people across twelve countries. Contrary to arguments in the literature, Muslims tend to be less concerned about climate change compared to Christians. Yet all Middle Easterners with a strong sense of religiosity are more concerned about climate change relative to their counterparts. Political attitudes also matter. Religious Muslims who endorse Islamist government are less concerned than secular Muslims, suggesting a “culture war” on the issue. These findings show that religion exerts a nuanced and unexpected influence on how people evaluate the climate change crisis.
Directed Acyclic Transformer Pre-training for High-quality Non-autoregressive Text Generation
Authors: Huang Fei , Ke Pei , Huang Minlie 
Published: August 2023

Abstract
Non-AutoRegressive (NAR) text generation models have drawn much attention because of their significantly faster decoding speed and good generation quality in machine translation. However, in a wider range of text generation tasks, existing NAR models lack proper pre-training, making them still far behind the pre-trained autoregressive models. In this paper, we propose Pre-trained Directed Acyclic Transformer (PreDAT) and a novel pre-training task to promote prediction consistency in NAR generation. Experiments on five text generation tasks show that our PreDAT remarkably outperforms existing pre-trained NAR models (+4.2 score on average) and even achieves better results than pre-trained autoregressive baselines in n-gram-based metrics, along with 17 times speedup in throughput. Further analysis shows that PreDAT benefits from the unbiased prediction order that alleviates the error accumulation problem in autoregressive generation, which provides new insights into the advantages of NAR generation.1
Τὸ κενὸν τοῦ πολέμου (Th. 3.30.4) and Its Uses in Greek and Latin Texts
Authors: Tsakmakis Antonis 
Published: August 2023

Abstract
The analysis of Thucydides 3.30.4 (from the speech of Teutiaplos), which contains the obscure phrase τὸ κενὸν τοῦ πολέμου, as well as of all occurrences of the same phrase in Greek and Latin texts confirms the reading κενόν against the vv.ll. καινόν and κοινόν, and helps establishing the meaning of the proverbial expression πολλὰ (τὰ) κενὰ τοῦ πολέμου. It does not refer to a mental state (illusion etc.), as has been generally assumed, but to a particular situation that can emerge in warfare. The ‘void of war’ means that one side is in a way neutralized. One of the two opponents is either unable or unwilling to fight, or is clearly inferior, to the degree that it withdraws or surrenders without a battle. The investigation of the proverb’s semantics also leads to a better understanding of the Thucydidean use and improves the understanding of Teutiaplos’ speech (Th. 3.30).
Cooperation and Competition

Abstract
This paper discusses relations between South Africa and Southern Rhodesia from 1939 to 1948. The article begins in 1939 when the outbreak of the Second World War brought mixed fortunes for the two neighbours. For Southern Rhodesia, which relied mainly on imported manufactured goods from the United Kingdom, the war induced shortages resulting in huge domestic demand. Shortages stimulated calls for local industry to fill the vacuum. Consequently, an import substitution industrialisation (ISI) drive developed. In addition to the ISI, South Africa, which had a comparatively established secondary industry by the time the war broke out, increasingly became an essential source for Southern Rhodesian imports. This, however, was not without its challenges. Southern Rhodesia’s economic interest groups often raised complaints against South Africa’s economic competition and its threat to the Rhodesian economy. Nonetheless, Pretoria and Salisbury worked closely and found ways to ease the challenges. By 1948, the end date of the paper, Southern Rhodesia and South Africa’s relationship had resulted in the signing of a Customs Union Agreement. Thus, the article demonstrates, thematically and chronologically, that relations between the two countries evolved through cooperation and competition during the Second World War until the onset of Apartheid in South Africa and the Customs Agreement. The paper relies on primary material from the Zimbabwean and South African archives comprised of correspondences of Customs Agreements negotiations, economic policies and relations, and Parliamentary debates.
The Second World War Memorial in Zambia
Authors: Tembo Alfred 
Published: August 2023

Abstract
Following the cessation of hostilities in Europe in 1945, a debate ensued in colonial Zambia on what was the best tribute to dedicate to its servicemen who had lost their lives in the Second World War. On the one hand, the colonial government advocated for conventional forms of a war memorial such as statues, obelisks, and triumphal arches. On the other side, African servicemen supported the idea of ‘living memorials’ in form of useful projects such as educational institutions, clinics or community centres. In the end, proponents of traditional memorials won this contest—eventually leading to the erection of a cenotaph in the heart of the seat of government. Using data from the National Archives of Zambia, this article argues that the erection of a cenotaph, was another blow to African servicemen who felt cheated by colonial authorities in the way they were to forever honour their dear departed compatriots.

Published: August 2023

Abstract
Raindrop size distributions (DSD) and rain rate have been estimated from polarimetric radar data using different approaches with the accuracy depending on the errors both in the radar measurements and the estimation methods. Herein, a deep neural network (DNN) technique was utilized to improve the estimation of the DSD and rain rate by mitigating these errors. The performance of this approach was evaluated using measurements from a two-dimensional video disdrometer (2DVD) at the Kessler Atmospheric and Ecological Field Station in Oklahoma as ground truth with the results compared against conventional estimation methods for the period 2006–17. Physical parameters (mass-/volume-weighted diameter and liquid water content), rain rate, and polarimetric radar variables (including radar reflectivity and differential reflectivity) were obtained from the DSD data. Three methods—physics-based inversion, empirical formula, and DNN—were applied to two different temporal domains (instantaneous and rain-event average) with three diverse error assumptions (fitting, measurement, and model errors). The DSD retrievals and rain estimates from 18 cases were evaluated by calculating the bias and root-mean-squared error (RMSE). DNN produced the best performance for most cases, with up to a 5% reduction in RMSE when model errors existed. DSD and rain estimated from a nearby polarimetric radar using the empirical and DNN methods were well correlated with the disdrometer observations; the rain-rate estimate bias of the DNN was significantly reduced (3.3% in DNN vs 50.1% in empirical). These results suggest that DNN has advantages over the physics-based and empirical methods in retrieving rain microphysics from radar observations.

Published: August 2023

Objective: The expression and significance of human epidermal growth factor receptor 2 (Her2) in upper tract urothelial carcinoma (UTUC) remains controversial. Thus, we aimed to systemically review the Her2 expression in UTUC patients and its relationship with pathological characters and clinical outcomes with meta-analysis. Materials and methods: A systematically computerized search in PubMed, Scopus, Embase and Cochrane was conducted. From a total of 454 related articles, 35 articles were finally reviewed and 16 papers were chosen for further analysis. Pathological characters included tumor stage, grade, lymph node metastasis (LNM) and lymphovascular invasion (LVI). The clinical outcomes included overall survival (OS), recurrence-free survival (RFS), cancer specific survival (CSS), metastatic-free survival (MFS) and progression-free survival (PFS). RevMan software was used for meta-analyses. Results: In total 16 studies from 1994 to 2020 were chosen, 14 studies used immunohistochemistry to assess the expression of Her2 and 5 studies used in situ hybridization, with a positive rate of 0 to 74.0% and 7.2 to 18.1%, respectively. Her2-positive was significantly associated with stage (pooled HR 1.86; 95 % CI 1.43–2.42), grade (pooled HR 2.81; 95 % CI 1.01–7.85) and LNM (pooled HR 1.93; 95 % CI 1.18–3.15). However, there was no statistically relationship between Her2-positive with LVI (pooled HR 1.48; 95 % CI 0.64–3.46) and RFS (pooled HR 1.41; 95 % CI 0.98–1.83). Conclusions: This review indicated that UTUC patients with Her2-positive tended to develop higher stage and grade tumors and LNM. The Her2 expression in UTUC patients deserves further investigation in the future.

Published: August 2023

Background Clinical trials on anti-calcitonin gene-related peptide monoclonal antibodies poorly investigated their impact on migraine accompanying symptoms. Objective To evaluate the impact of basal accompanying symptoms on anti-CGRP monoclonal antibodies treatment response and their evolution after six months of treatment in migraine patients. Methods Patients with migraine diagnosis seen in the Headache Clinic and treated with erenumab, galcanezumab or fremanezumab were prospectively recruited. They completed a daily eDiary which provided data on headache frequency and the following accompanying symptoms of each day: photophobia, phonophobia, nausea, dizziness, and aura. Patients were classified as responders or non-responders based on 50% or greater reduction in headache days per month at month 6 (≥50% response rate). Accompanying symptoms ratios based on headache days per month were assessed per patient at baseline and after three and six months. Comparisons for basal characteristics, basal accompanying symptoms ratios and their evolution after six months between responders and non-responders were performed. Results One hundred and fifty-eight patients were included, 44% (69/158) showed ≥50% response rate after six months. A significant reduction in headache days per month in both groups was found at month 6 (−9.4 days/month in ≥50% response rate group; p < 0.001, −2.2 days/month in <50% response rate group; p = 0.004). Additionally, significant decreases in photophobia (−19.5%, p < 0.001), phonophobia (−12.1%, p = 0.010) and aura ratios (−25.1%, p = 0.008) were found in ≥50% response rate group. No statistically significant reductions were found in nausea and dizziness in any group since their reduction was correlated with the decrease in headache days per month. Higher photophobia ratios at baseline were predictive of an increased response between months 3 and 6 (Incidence Risk Ratio = 0.928, p = 0.040). Conclusions The days per month with photophobia, phonophobia and aura decreased at a higher rate than headache days per month after six months in the ≥50% response group. Higher photophobia ratios were associated with higher response rates between three and six months. It could indicate an involvement of peripheral CGRP in photophobia as well as a central modulation of migraine through these treatments which mainly act on the periphery.

Authors: Sarkar Debansu , Tandon Mrinal , Pal Dilip Kumar 
Published: August 2023

Background: Anxiety and depression are commonly seen with urinary incontinence (UI) and its association is strongest for urgency and mixed UI. It affects the quality of life and functional status. Aims: To assess the prevalence and severity of anxiety and depression in SUI (Stress urinary incontinence) and UUI/MUI (Urge or mixed urinary incontinence), to assess the severity of SUI and UUI/MUI and its association with anxiety and depression and to identify various factors associated with anxiety and depression. Materials and methods: An observational study using various tools as history regarding urinary incontinence, history of other prior events which can lead to anxiety or depression, age, educational level, BMI (Body mass index), HADS scale (Hospital anxiety and depression scale) for anxiety and depression and ICIQ-UI-SF score (International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form). Results: The Prevalence of anxiety and depression in UUI/MUI was higher. More women were overweight (BMI > 25) in the UUI/MUI group. Higher prevalence of anxiety and depression in the very severe urinary incontinence group. No association of the level of education with anxiety and depression in women with urinary incontinence. Conclusion: Anxiety and depression are more in UUI/MUI patients compared to SUI. In obese ladies, UUI is more prevalent compared to SUI. Anxiety and depression are more with increasing severity of incontinence. Anxiety and depression have no association with the educational status of the patients.
