SunMap: A Solar Image Processing Software for Obtaining Synoptic Maps
Authors: Bernabé Sergio , García Gabriel , Carrasco Víctor M. S. , Vaquero José M. 
Published: August 2022

AbstractA new open-source software, called SunMap, has been developed to obtain synoptic maps in an easy and quick way from multiple full-disc solar images. Our objective is to provide a free and straightforward application for heliophysicists and geophysicists interested in generating solar synoptic maps. SunMap allows comparison of structures and patterns of solar activity over various periods. Thus, the short- and long-term evolution of solar regions of interest can be studied. To reach this goal, different solar images taken day by day are stored in a single map that uses a sequence of images and allows the positioning of each observable element on it. A simple comparison between a synoptic map generated by SunMap and another previously constructed map is presented to show the versatility of this new available software.

Published: August 2022

AbstractThis paper presents a new number representation based on logarithmic number system (LNS) called unsigned logarithmic number system (ulog), as an alternative to the conventional floating-point (FP) number format, to use in approximate computing applications. ulog is tailored for software implementation on commercial general-purpose processors, and uses the same dynamic range as conventional IEEE Standard FP formats to prevent overflow and underflow. ulog converts FP numbers to fixed-point numbers and uses integer operations for all computations. Moreover, vectorization and approximate logarithmic addition have been used to increase the performance of the software implementation of ulog. Then, we used different BLAS benchmarks to evaluate the performance of the proposed format than IEEE standard formats. 16- and 32-bit ulog improve the runtime than double-precision at most 70.26% and 46.36%, respectively. Besides, accuracy analysis of the ulog based on different logarithm bases showed that base 4 has the lowest error in most cases.

AbstractThe present work elucidates a novel way of processing Al–Si–Al2O3 bulk nanocomposites. The novel approach includes synergetic effect of non-contact ultrasonication and mushy state rolling for achieving appreciable uniformity in the distribution of nanoparticles in the metal matrix. A systematic study on the distribution of particles, the resultant microstructure, and also the resultant hardness in the nanocomposite has been presented. It is shown that the current methodology has resulted in enhanced distribution of nanoparticles in the metal matrix as compared to the earlier versions in the field. The structure of the nanocomposites has been explained on the basis of cavitation phenomena and particle pushing during solidification. The work also includes simulation using the Fluent platform to estimate the time available before the initiation of solidification to carry out effective deagglomeration and distribution of nanoparticles in the liquid melt using ultrasonic cavitation. Although the non-contact ultrasonic casting has resulted in a nearly uniform deagglomeration of nanoparticle clusters, a small number of agglomerates were present at the grain boundaries. Hence, the as-cast nanocomposites were deformed in the mushy state condition. An attempt has been made to explore the feasibility of enhancing the distribution of nanoparticles in the Al–Si matrix through semisolid state rolling. The synergetic effect has resulted in enhancement of the hardness of the material by 37%.

Published: August 2022

Abstract
Background
Anemia might contribute to the development of secondary injury in patients with acute traumatic brain injury (TBI). Potential determinants of anemia are still poorly acknowledged, and reported incidence of declined hemoglobin concentration varies widely between different studies. The aim of this study was to investigate the incidence of severe anemia among patients with moderate to severe TBI and to evaluate patient- and trauma-related factors that might be associated with the development of anemia.

Methods
This retrospective cohort study involved all adult patients admitted to Tampere University Hospital’s emergency department for moderate to severe TBI (August 2010 to July 2012). Detailed information on patient demographics and trauma characteristics were obtained, including data on posttraumatic care, data on neurosurgical procedures, and all measured in-hospital hemoglobin values. Severe anemia was defined as a hemoglobin level less than 100 g/L. Both univariate and multivariable analyses were performed, and hemoglobin trajectories were created.

Results
The study included 145 patients with moderate to severe TBI (male 83.4%, mean age 55.0 years). Severe anemia, with a hemoglobin level less than 100 g/L, was detected in 66 patients (45.5%) and developed during the first 48 h after the trauma. In the univariate analysis, anemia was more common among women (odds ratio [OR] 2.84; 95% confidence interval [CI] 1.13–7.15), patients with antithrombotic medication prior to trauma (OR 3.33; 95% CI 1.34–8.27), patients with cardiovascular comorbidities (OR 3.12; 95% CI 1.56–6.25), patients with diabetes (OR 4.56; 95% CI 1.69–12.32), patients with extracranial injuries (OR 3.14; 95% CI 1.69–12.32), and patients with midline shift on primary head computed tomography (OR 2.03; 95% CI 1.03–4.01). In the multivariable analysis, midline shift and extracranial traumas were associated with the development of severe anemia (OR 2.26 [95% CI 1.05–4.48] and OR 4.71 [95% CI 1.74–12.73], respectively).

Conclusions
Severe anemia is common after acute moderate to severe TBI, developing during the first 48 h after the trauma. Possible anemia-associated factors include extracranial traumas and midline shift on initial head computed tomography.

AbstractThe twelve wells were selected to carry out the various test, duration of pumping (min), maximum draw drown (m), duration of recovery (min), residual drawdown, and aquifer type in the basaltic rock aquifer parameters of Buchakewadi watershed. The source and flow of groundwater are essential concerns in hydrological systems that concern both spatially and temporally components of groundwater discharge and water supply problems. The content and temperature of groundwater flowing through an aquifer might change depending on the aquifer environment. As a result, hydrodynamic analyses can provide valuable information about a region's subsurface geology. The present research attempts of aquifer variables such as transmissivity (T) and storativity (S) estimation are significant for groundwater resource development and evaluation. There are numerous approaches for calculating precise aquifer characteristics (i.e., hydrograph analysis, pumping test, etc.). A most frequent in situ analysis is a well-pumping test, which accurately measures the decline and rise of groundwater levels. During an aquifer pumping test, to characterize aquifer properties in an undiscovered location to forecast the rate of depletion of the groundwater table/potentiometric surface. The shallow, weathering subsurface water accessible above the Deccan traps in an unconfined state is insufficient to satisfy the ever-increasing pressure on water supplies. Maharashtra is similarly dominated by hard rocks, whose rainfall susceptibility is limited by weathering and primary porosity, as is their volume to store and convey water. Based on the hydraulic parameters and Theis method, results are optimized. Aquifer mapping and pumping test results can be more important for solving problems such as water scarcity, nonpolluting water, health issues, and source of fresh water on the earth surface. However, the characterization of aquifer parameters should be significant role in the scientific planning and engineering practices.

AbstractThis opinion piece emerged from research for the book, Story Machines: How Computers Have Become Creative Writers, by Mike Sharples and Rafael Pérez y Pérez, published by Routledge. While thinking of ways to promote the book, I realised that students could employ AI story generators to write essays. That led me to research automated essay writing, write a Twitter thread that has garnered 43,000 engagements, and author a blog article (Sharples, 2022). The current piece is a revised and expanded version of that article.

Published: August 2022

AbstractStudent drop-out is one of the most critical issues that higher educational institutions face nowadays. The problem is significant for first-year students. These freshmen are especially at risk of failing due to the transition from different educational settings at high school. Thanks to the massive boom of Information and Communication Technologies, universities have started to collect a vast amount of study- and student-related data. Teachers can use the collected information to support students at risk of failing their studies. At the Faculty of Mechanical Engineering, Czech Technical University in Prague, the situation is no different, and first-year students are a vulnerable group similar to other institutions. The most critical part of the first year is the first exam period. One of the essential skills the student needs to develop is planning for exams. The presented research aims to explore the exam-taking patterns of first-year students. Data of 361 first-year students have been analysed and used to construct “layered” Markov chain probabilistic graphs. The graphs have revealed interesting behavioural patterns within the groups of successful and unsuccessful students.

Published: August 2022

AbstractTriboelectric nanogenerator (TENG) is regarded as an effective strategy to convert environment mechanical energy into electricity to meet the distributed energy demand of large number of sensors in the Internet of Things (IoTs). Although TENG based on the coupling of triboelectrification and air-breakdown achieves a large direct current (DC) output, material abrasion is a bottleneck for its applications. Here, inspired by primary cell and its DC signal output characteristics, we propose a novel primary cell structure TENG (PC-TENG) based on contact electrification and electrostatic induction, which has multiple working modes, including contact separation mode, freestanding mode and rotation mode. The PC-TENG produces DC output and operates at low surface contact force. It has an ideal effective charge density (1.02 mC m−2). Meanwhile, the PC-TENG shows a superior durability with 99% initial output after 100,000 operating cycles. Due to its excellent output performance and durability, a variety of commercial electronic devices are powered by PC-TENG via harvesting wind energy. This work offers a facile and ideal scheme for enhancing the electrical output performance of DC-TENG at low surface contact force and shows a great potential for the energy harvesting applications in IoTs.
The spirit is willing, but the institutions are weak: disclosure of corporate social responsibility and the financial sector in transition
Authors: Djalilov Khurshid , Hartwell Christopher A. 
Published: August 2022

AbstractEvidence exploring the relationship between corporate social responsibility (CSR) disclosure and corporate financial performance (CFP) is consistently inconsistent, if not outright contradictory. We assert that much of this confusion is due to a failure to integrate both firm internal performance and the external environment into theoretical and empirical analyses of the effect of CSR disclosure on firm efficiency. This paper attempts to bring these two facets together in an examination of banking sector efficiency in a situation where the entire external environment is in flux, namely transition. Using a database of 319 banks from 21 transition countries, and using dynamic panel and quantile regressions, we provide empirical evidence that banks in transition countries saw benefits in firm performance only when CSR activities were layered on top of a strategy which already was profitable. Indeed, once profitability was achieved, only then did CSR disclosure begin to confer a competitive edge in developing firm resources. However, the external environment continues to exert an influence, and even where banks met profitability goals, predatory institutions can still make engaging in CSR a detriment to competitive advantage.
Liver transplantation in a patient with massive polycystic liver disease: A case report and literature review
Authors: Deng Qingsong , Liu Fenghao , He Minglian , Ou Yanjiao , Zhang Leida 
Published: August 2022

ABSTRACT

Introduction and importance:
Liver transplantation (LT) is rarely performed and challenging but is the only curative treatment option for severe polycystic liver disease (PLD). LT can cause hemorrhage and is not standardized. We performed a routine operation for smooth, giant liver cysts, with minimal intraoperative bleeding.

Case presentation:
We report a case of a 38-year-old female who was hospitalized for emaciation with abdominal distension for 5 years that became worse for 1 year. She was diagnosed with massive PLD complicated by liver cirrhosis, splanchnic varices and ascites that led to reduced activity, diminished ability to live independently and reduced quality of life; she successfully underwent LT.

Clinical discussion:
The patient had a large volume of hepatic cysts and little normal liver parenchyma, resulting in obvious clinical symptoms untreatable with routine surgery. The only curative surgical option for patients with severe symptoms is LT. The patient recovered smoothly after LT. We conclude that the only radical method for treating large polycystic liver lesions is LT in a conventional operation. Intraoperative bleeding was minimal. The anhepatic phase and revascularization time did not differ from those of conventional LT. The patient recovered well postoperatively.

Conclusion:
A literature review suggests that the only radical treatment for giant polycystic liver is LT. At present, most of the literature is case reports or summary analyses of a small sample of cases. A long-term (more than 20 years) survival analysis suggests that LT has a low incidence of surgical complications and a good long-term curative effect.

Women, Peace and Security National Action Plans in anti-gender governments: The cases of Brazil and Poland
Authors: Thomson Jennifer , Whiting Sophie 
Published: August 2022

AbstractIn recent years, Brazil and Poland have elected governments that are sceptical of both the liberal international order and gender. In both cases, contemporary administrations have bolstered the pre-existing anti-gender offensive of religious and secular conservative forces and converted this into legislation and public policy. Yet, at the same time, both have also created National Action Plans around the UN's Women, Peace and Security agenda. Why is this the case? Why do two governments that see gender as an ‘ideology’ continue to work on WPS? Using a feminist institutionalist framework, this article draws on content analysis of the NAPs and semi-structured in-depth interviews with stakeholders in Brazil and Poland to explore this puzzle. We argue that the WPS agenda has survived in these political contexts due the presence of key ‘femocrats’ within the state; the influence of international institutions; and the symbolic power that the WPS agenda gives to these countries on the world stage. As such, the article makes a key contribution to the literature on the WPS agenda and also bolsters the argument for a complication of the idea of gender ‘backlash’ – in domestic and international audiences, states are willing to adopt different attitudes to gender if it furthers their interests.

Published: August 2022

AbstractBackgroundPrevious studies have examined public psycho-behavioural responses in the early stages of the epidemic, little is known after mass vaccination has been implemented. This study aimed to investigate the public's behavioural (adoption of COVID-19 precautionary measures) and psychological (depression, anxiety and stress) responses to COVID-19 and their relationships after the launch of the territory-wide vaccination programme in Hong Kong.MethodsA cross-sectional survey study using anonymous online or face-to-face questionnaires was conducted between June 2021 and September 2021. A convenience sample of Hong Kong Chinese residents aged ⩾18 years were recruited online by referrals and from a university-run community vaccination centre.ResultsA total of 1893 valid questionnaires were received. The results showed that Hong Kong residents have high levels of adoption of precautionary measures and low levels of depression, anxiety and stress after the mass vaccination. Hierarchical regression analysis identified that in the fully adjusted model, the adoption of precautionary measures was a consistent protective factor (β ranged −1.51 to −1.67, p < 0.001) for depression, anxiety and stress amid the COVID-19 pandemic.ConclusionsThis study offers new information on the public's psycho-behavioural responses to the pandemic, as well as insights into public health planning after introducing the mass vaccination.
What Do We Know about Power Sharing after 50 Years?

Published: August 2022

AbstractThe power-sharing literature lacks a review that synthesizes its findings, despite spanning over 50 years since Arend Lijphart published his seminal 1969 article ‘Consociational Democracy’. This review article contributes to the literature by introducing and analysing an original dataset, the Power Sharing Articles Dataset, which extracts data on 23 variables from 373 academic articles published between 1969 and 2018. The power-sharing literature, our analysis shows, has witnessed a boom in publications in the last two decades, more than the average publication rate in the social sciences. This review offers a synthesis of how power sharing is theorized, operationalized and studied. We demonstrate that power sharing has generally positive effects, regardless of institutional set-up, post-conflict transitional character and world region. Furthermore, we highlight structural factors that are mostly associated with the success of power sharing. Finally, the review develops a research agenda to guide future scholarly work on power sharing.
Investigating the radical right's family policy agenda: evidence from six European countries
Authors: Giuliani Giovanni Amerigo 
Published: August 2022

AbstractThe positions of the radical right parties (RRPs) concerning the family have generally been examined through a socio-cultural lens, but very little is known about their distributive preferences. Based on the theoretical insights from the literature on varieties of familialism and social investment, the article investigates the RRPs' family policy agenda in terms of preference and support for familialism and de-familialism. Furthermore, cross-country similarities and differences will be investigated through an explanatory framework that combines the literature on partisan politics with that on historical institutionalism. A content analysis of party manifestos has shown that the RRPs adopt a male-breadwinner policy agenda, mostly intended to please their authoritarian electorate. However, comparative empirical research has highlighted some cross-country differences. These are explained by considering the counter-feedback mechanism triggered by the policy legacies, which provides RRPs with divergent electoral incentives and disincentives to promote their family policy agenda.
Failure modes in fluid saturated rocks: deformation processes and mode-switching
Authors: Hobbs Bruce , Ord Alison 
Published: August 2022

AbstractWe consider the implications of adding a cap to the yield surface for elastic–plastic and elastic–visco-plastic solids with coupling between deformation, fluid flow and mineral reactions. For a suitable combination of (low) permeability and strain rate, opening-mode veins can form in compression. Such behaviour is enhanced by dissolution and by simultaneous mineral reactions with negative ΔV. These are the opening-mode equivalents of compaction bands in rocks with high permeability. Stylolite parallel veins are considered as forming in this way; such veins are commonly the laminated or ribbon-quartz veins associated with intense gold mineralization. Axial plane veins and melt segregations are in this class also. The addition of a yield surface cap limits the permissible stress states portrayed by a failure-mode diagram and has implications for breccia formation. Failure discontinuities that form at the cap require adecreasein fluid pressure to form as opposed to extension joints and veins that require anincreasein fluid pressure; discontinuities that form at the cap are in orientations that are commonly interpreted as reactivated early discontinuities. The switching between high fluid pressure and low fluid pressure, which we callmode-switching, arises from competition between mineral dissolution and deposition. This is an alternative to the fault-valve mechanism and does not require fault reactivation or failure at a ‘seal’ linked to seismicity or fault reactivation. The capped yield surface concept provides a unifying self-consistent approach for vein/breccia formation and for the kinematics of brittle and visco-plastic rocks.
