The Relationship Between TGF Production in Thunderstorms and Lightning Flash Rates and Amplitudes

We provide evidence that Terrestrial Gamma‐Ray Flashes (TGFs), in well isolated thunderstorms, tend to occur during periods of low and declining flash rates, and when the flash amplitudes are larger than average. This conclusion comes from examining the results of 371 manually tracked TGF‐producing thunderstorms. Fermi‐GBM identified TGFs are used for this analysis and lightning data come from both World Wide Lightning Location Network and Earth Networks Total Lightning Network. The data from these storms suggest that TGFs are likely to occur in almost every phase of storms that last longer than an hour, but tend to occur later on in shorter storms. We also note that, in short storms, TGFs are more likely to accompany a flash when the flash rates of the storm are lower than average, and they are less likely per flash during the peak flash rate periods of the storms. We find that the tendency for TGFs to occur while the flash rate is falling and when the amplitudes of flashes (the sum of the absolute values of peak currents of all constituent sferics in the flash) are larger than average, does not depend strongly on the duration of the storms. This implies that not just any lightning flash can or even will produce a TGF, but that the electrical conditions of the storm play a crucial role in TGF production.
DESIGN AND IMPLEMENTATION OF A PROMISING OPTICAL SUBSYSTEM WITH A SKY CAMERA FOR LASER WARNING SYSTEMS

In the last few decades, a Significant advance in the laser detection techniques have occurred in a civilian application like optical fiber communication system, lidar system and now satellite communication in the aerospace and a military application, one of the most applications in military is the laser guided missiles and bombs encountered high development and formed high threat for strategic and special targets. The development of a laser warning system (LWS) is essential to detect the laser guided weapons attack. A classic LWS is composed of an optical subsystem, laser detector, and processing unit. The design of a LWS is constrained by the cost, optical system size, detector type, and the required processing operations. In this paper, a 15-degree field of view optical subsystem, diffraction grating, and a sky camera is used to reduce the whole system size, reduce the cost, and decrease the number of false alarms initiated by the dark current on the classical detectors. The optical subsystem is designed to shape the laser spot diameter to be 350µm to avoid detection saturation. The design and fabrication of the optical system guaranteed a signal-to-noise ratio up to 175dB in a clear atmospheric condition. This LWS outperforms the state-of-art LWSs in laser guided weapon detection.
Household Food Consumption and Wastage during the COVID-19 Pandemic Outbreak: A Comparison between Peru and Brazil

The COVID-19 pandemic has represented a major global challenge. In Latin America, both Brazil and Peru reported the highest levels of impact in terms of proportional infection and death rates. Within this context, this study sought to compare food consumption and wastage patterns in Peruvian and Brazilian households. For these purposes, the authors conducted a quantitative research study based on a self-reported online survey submitted during the pandemic outbreak. Results revealed that the intention of reducing food wastage and implementing leftover management routines are related to the economic value of wasted food. In addition, in both countries, shopping lists are used as planning elements, and food purchases are influenced by on-sale products. Leftover management is also similar in both countries, and the expiration date on the label is the most commonly used criterion for consuming or discarding food items. Nevertheless, within the framework of the health and economic crisis generated, opportunities for change toward the adoption of smarter and more sustainable purchasing behaviors are emerging for both households and companies, in addition to giving equal importance to environmental, social, and economic benefits. This research study provided insights into food consumption and food wastage behaviors in times of crisis, such as a pandemic.
Evaluation of satellite land surface albedo products over China using ground-measurements

ABSTRACT Land surface albedo (LSA) is an important parameter in surface energy balance and global climate change. It has been used in the fields of energy budgets, climate dynamics, and land surface processes. To apply satellite LSA products more widely, the product accuracy needs to be evaluated at different scales and under atmospheric and surface conditions. This study validates and analyzes the errors of the LSA datasets from the Global LAnd Surface Satellites (GLASS) product, the European Space Agency’s Earth Observation Envelope Programme (GlobAlbedo), the Quality Assurance for Essential Climate Variables (QA4ECV) project, the Gap-filled Snow-free Bidirectional Reflectance Distribution Function (BRDF) parameters product (MCD43GF), and the Satellite Application Facility on Climate Monitoring (CM SAF) Albedo dataset from the AVHRR data (CLARA-SAL) against the Chinese Ecosystem Research Network (CERN) measurements at different spatiotemporal scales over China from 2005 to 2015. The results show that LSA estimated by GLASS agrees well with the CERN measurements on a continental scale. The GLASS product is characterized by a correlation coefficient of 0.80, a root-mean-square error of 0.09, and a mean absolute error of 0.06. The consistency between GLASS, GlobAlbedo, and CLARA-SAL is slightly lower over the regions with high aerosol optical depth (AOD) (e.g. Sichuan Basin, northern China) and high cloud cover compared with that in regions with lower AOD and low cloud cover. The estimation errors are related to varying atmospheric and surface conditions and increase with increasing AOD and cloud cover and decreasing enhanced vegetation index. Therefore, algorithms under complex atmospheric and surface conditions (e.g. high AOD, sparse vegetation) should be optimized to improve the accuracy of LSA products.
Preposition stranding under sluicing: Evidence from Hijazi Arabic

Based on data from numerous languages, such as English, Frisian, and Danish, Merchant (2001) proposes the preposition stranding generalization (PSG), which states that only languages that allow preposition stranding under wh-movement also allow preposition stranding under sluicing. The availability of this generalization has been the subject of a number of studies. Two contrasting views have been identified in the literature. The first view confirms the availability of the PSG in a number of different languages. The other view claims that this generalization is untenable as there exist non-preposition stranding languages that allow preposition stranding under sluicing. Our aim in this paper is to examine the availability of the PSG in the dialect of Hijazi Arabic (HA). Based on empirical data from HA on the syntactic behavior of preposition stranding under wh-movement and under sluicing, we argue that this PSG does not hold in HA. It has been observed that HA is like Emirati Arabic, Brazilian Portuguese, and Indonesian in that it disallows preposition stranding under wh-movement but allows it under sluicing. Therefore, the results of this research may contribute to the ongoing discussions on the phenomenon of sluicing in linguistic theory to help obtain a more universal analysis of this interesting ellipsis construction.
Diffusion of the Balanced Scorecard: motives for adoption, design choices, organisational fit, and consequences

ABSTRACT The purpose of this exploratory study is to understand how the motives behind a Balanced Scorecard (BSC) adoption affect the BSC's design, organisational fit, and consequences from a diffusion theory perspective. Using semi-structured interviews, we follow up on three organisations that are long-term adopters of the BSC. We find that the motives for adopting the BSC do not follow the conventional model whereby early adopters have economic (rational) and late adopters non-economic (social) motives, but that these motives interact during the diffusion process. These organisations reframed the BSC and bundled it with other practices to achieve a better cultural, technical and political fit (i.e. top-management-related factors and IT systems). Cultural misfits are the most formative and can overpower technical and political aspects of fit. This has led to management practices that differ from the original design of the BSC. Also, we critically assess consequences of the BSC adoptions. Even adopters emphasising economic motives for adopting the BSC did not attempt to assess its ex-post financial impact. Thereby, our study contributes a critical view on fashionable management innovations.
An Examination of Religious Schemas through the Lens of Self-Determination Theory

Abstract Religious development literature in Christian higher education has successfully utilized Self-Determination Theory to explain how environmental factors predict faith maturity in college students. Recent trends suggest a need to account for more ecumenical perspectives in contemporary evangelical college students, and this study addresses the need by measuring religious schemas. Using a mixed methods design, the researchers measured three schemas, (a) truth in text, (b) fairness tolerance and rationality, and (c) xenosophia, using the Religious Schema Scale (RSS), in 871 students at a Christian evangelical university located in the central region of the United States. Multiple regression analysis calculated how environmental factors of autonomy support and religious pressures predicted RSS scores, while controlling for year in school and religious denomination. Students’ descriptions of self-perceptions of spiritual growth were analyzed for possible positioning along the Self-Determination Continuum and determining the role the university played in spiritual growth. Results found that only the truth in text schema is predicted by increases in both environmental factors; the fairness tolerance and rationality schema is predicted by higher religious pressures; and the xenosophia schema is predicted by lower religious pressures. Researchers concluded that Christian evangelical universities would benefit from expanding current religious development conversations, addressing pluralism, and incorporating a higher consciousness regarding diversity, to better meet the religious development needs of contemporary Christian evangelical students.
A PILOT STUDY FOR EVALUATION OF ROLE OF B-MODE ULTRASOUND AND STRAIN ELASTOGRAPHY IN DIFFERENTIATING BENIGN AND MALIGNANT BREAST MASSES

Background: Early detection of malignant lesions is critical key stone for the successful management of breast cancer. Conventional B-mode ultrasound although could not replace the histopathology which is still gold standard, plays an important role in the diagnostic pathways by using the Breast Imaging Reporting and Data System (BIRADS) lexicon (standardized by American College of Radiology [ACR]). Although characterization of solid breast masses by sonography has improved greatly since the early 1990s, specificity remains low and a large number of biopsies result in benign diagnosis. Strain elastography and strain ratio (SR) are recent techniques which may help in increasing the specificity of ultrasound. Methods: The present study was a pilot study aimed to establish a correlation between B-mode ultrasound and strain elastography in differentiating benign and malignant breast masses and to compare the results of B- mode ultrasound and Strain Elastography with fine-needle aspiration cytology/ biopsy findings. It was a prospective study conducted in the Department of Radio-diagnosis of Rajindra Hospital, Patiala. A total of 40 patients who presented with the complaint of palpable breast lump were evaluated with B-Mode Ultrasonography (USG) and Strain elastography (using elastography score [ES] and SR). Results: The study group (40 patients with breast lumps) comprised 38 (95%) female patients and 2 (5%) male patients. Among the group 29 were benign and 11 were malignant. Fibroadenoma followed by fibrocystic disease was the most common benign pathologies and invasive ductal carcinoma followed by Ductal Carcinoma in situ was the most common malignant pathologies. Sensitivity, specificity, and diagnostic accuracy of B-Mode USG in diagnosing palpable breast lump are 72.7%, 86.2%, and 82.5%, respectively, while that of strain elastography in diagnosing palpable breast lump are 81.8%, 93.10%, and 90.0%, respectively. Using strain ratio (SR) only the sensitivity, specificity, and diagnostic accuracy was found to be 93.1%, 100%, and 95% better than B-Mode USG and shear elastography alone separately and combined. The mean SR for a benign mass is 2.00±0.97 and for a malignant mass is 5.40±1.55. Conclusion: Ultrasound elastography (using ES) has a higher sensitivity, specificity and diagnostic accuracy in differentiating benign and malignant breast masses then B mode USG (using BIRADS). Using SR alone has shown better sensitivity, specificity, and diagnostic accuracy but its standalone or in combination diagnostic application has to be followed up with further studies.
A place and time for humor: leader humor in Confucian cultures

Humor has been positively perceived in general. However, research has shown that a leader should adopt humor with care and only after considering the relevant context, such as cultural differences. This study was undertaken to gain insight into how leader humor is perceived in the predominantly Confucian culture of Taiwan, through a series of in-depth interviews with individuals from throughout the hierarchies of various organizations. Overall, our participants expressed conflicting attitudes toward leader humor in the workplace, depending on the place and time of their leader humor experience. Specifically, leader humor was deemed more effective in informal domains and when a good leader–follower relationship exists. The findings echo the implicit theory of leadership and highlight the need to consider the context when exercising leader humor in Confucian cultures. Implications and future study directions are discussed.
Poor Photovoltaic Performance of Cs3Bi2I9: An Insight through First-Principles Calculations

Bismuth-based halide perovskite derivatives have now attracted huge attention for photovoltaic (PV) applications after the unparalleled success of lead-based halide perovskites. However, the performances of PV devices based on these compounds are poor, despite theoretical predictions. In this Article, we have investigated the electronic structure and defect formation energies of Cs3Bi2I9 using density functional theory (DFT) calculations. The calculated electronic bandstructure indicates an indirect bandgap and high carrier effective masses. Our calculations reveal a large stability region for this compound; however, deep level defects are quite prominent. Even the varying chemical potentials from the stoichiometric region do not eliminate the presence of deep defects, ultimately limiting photovoltaic efficiencies.
Social-material aspect of navigation technology: using structural topic models to identify the causes of ship accidents (1973–2018)

Abstract What are the major factors contributing to ship accidents, and how do these factors evolve in the long term? This study addresses these two questions by leveraging an unsupervised machine learning method named structural topic modelling to identify the causes of ship accidents. The study analysed 2,341 task errors manually collected from 441 reports issued by four government agencies covering a 45-year time span. The results show that the structure of causes of ship accidents remained essentially the same during this period. This highlights the social-material aspect of navigation technology, indicating that the use of advanced technology may not necessarily lead to safer navigation practices, and the interaction between the technology and human agency must be focused on in the bridge management context. Additionally, the computer-assisted textual data analysis highlights pilot-related factors, which might be rooted in the unsupervised and difficult-to-verify handover procedures between pilots and captains, thereby underlining the importance of appropriate piloting regulations.
Brain Atrophy and Physical and Cognitive Disability in Multiple Sclerosis

Introduction: Brain atrophy is associated with physical disability in multiple sclerosis (MS), but there is a great variability between different studies and methodologies, and its use is still limited to research projects. We aimed to analyze the relationship between several volumetric measurements and physical disability and cognitive functioning in MS patients in a clinical practice setting. Methods: This is a cross-sectional study. A total of 41 patients (31 relapsing-remitting MS, 6 secondary-progressive MS, and 4 primary-progressive MS) were included. Whole brain volume (WBV), gray matter volume (GMV), and T2 lesion load (T2L) were obtained using Icometrix® software. Physical disability was measured with the Expanded Disability Status Scale (EDSS), and cognitive status was evaluated with the brief repeatable battery of neuropsychological tests (BRB-N). The relationship between brain volumes and EDSS was analyzed through linear multivariate regression. The association between volumetry measurements and the number of affected cognitive domains was studied with negative binomial regression. Results: GMV was associated with age (b=-1.7, P=0.014) and with EDSS (b=−7.55, P=0.013). T2L was associated with EDSS (b=2.29, P=0.032). The number of affected cognitive domains was associated with clinical phenotype, worse in primary progressive MS (PPMS). There was not correlations between cognitive impairment and cerebral volumes. Conclusion: Brain atrophy measurement is feasible in clinical practice setting, and it is helpful in monitoring the EDSS progression. Primary progressive phenotype is associated with greater risk of cognitive dysfunction. Highlights The T2 lesion load is associated with physical disability in patients with multiple sclerosis (MS). The gray matter volume is associated with age and physical disability in patients with MS. There is no significant correlation between cognitive impairment and cerebral volumes in patients with MS. Plain Language Summary Conventional magnetic resonance imaging (MRI) is still used for diagnosing and monitoring multiple sclerosis (MS). Analysis of Brain volumes including Whole brain volume (WBV), gray matter volume (GMV), and T2 lesion load (T2L) allows the evaluation of its neurodegenerative mechanisms. Robust evidence links brain atrophy with disability in MS. This study aims to analyze the relationship between advanced MRI sequences and physical disability and cognitive functioning in MS patients. According to the results, T2L was associated with physical disability and GMV was associated with age and physical disability. There was no significant correlation between cognitive impairment and cerebral volumes in patients with MS.
A fatigue model for spiral bevel gears under mixed elastohydrodynamic lubrication conditions

Many contributions have focused on the pitting analysis in gear transmissions. However, studies on pitting fatigue in spiral bevel gears are limited due to the complexity of tooth contact and lubrication analysis. This paper is to present a reasonable methodology to simulate the pitting crack nucleation of spiral bevel gears considering the real three‐dimensional (3D) rough surface contact where the intermittent asperity stress concentrations is prominent. The proposed model includes a loaded tooth contact analysis model, a mixed elastohydrodynamic lubrication model proposed previously, 3D stress filed formulation, and multi‐axial fatigue criterions. In order to determine an appropriate multi‐axial fatigue criterion for spiral bevel gear, a characteristic plane approach and a conventional critical plane approach are employed in this study. The predicted micro‐pitting lives are compared to published micro‐pitting investigations to assess the reliability of two fatigue criterions in simulation of the micro‐pitting failure. It is observed that the characteristic plane approach is better to reveal the failure mechanism in spiral bevel gears.
Revision of Immersaria and a new lecanorine genus in Lecideaceae (lichenised Ascomycota, Lecanoromycetes)

﻿Abstract The species Immersariacupreoatra has been included in Bellemerea. This caused us to reconsider the relationships between Bellemerea and the lecanorine species of Immersaria and to question the monophyly of Immersaria. Amongst 25 genera of the family Lecideaceae, most have lecideine apothecia, the exceptions being Bellemerea and Koerberiella, which have lecanorine apothecia. According to previous classifications, Immersaria included species with both lecanorine and lecideine apothecia. A five-loci phylogenetic tree (nrITS, nrLSU, RPB1, RPB2, and mtSSU) for Lecideaceae showed that Immersaria was split into two clades: firstly, all the lecideine apotheciate species and secondly, all the lecanorine apotheciate species. The latter clade was closely related to the remaining lecanorine apotheciate genera: Bellemerea and Koerberiella. Therefore, the genus concept of Immersaria is revised accordingly and a new lecanorine genus Lecaimmeria is proposed. Furthermore, four new species for Immersaria and seven new species and three new combinations for the new genus Lecaimmeria are proposed. Keys to Immersaria and the new genus Lecaimmeria are provided.
The impact of media use on the spillover and crossover effect of couple conflict

This 5-day daily diary study examined the influence of media use on the spillover and crossover effect of couple conflict among married and dating couples. Couples aged 18–38 years recorded their daily overload, negative mood, couple conflict, media use, flooding, and satisfaction. The results showed negative spillover and crossover effects: individuals reported more negative moods and couple conflict in response to their own and their partners’ increase in daily overload. Following media synchronicity theory, the more synchronous media couples used in conflict, the more they resolved the conflict. In addition, the more couples segmented their channels, the less they flooded and the more they resolved the conflict. The results suggest that dating and married couples might benefit from managing conflict associated with spillover and crossover effects using synchronous channels that are segmented.
Pulmonary Melioidosis Masquerading as Tuberculosis: A Case Report

Tuberculosis is most common chronic lung infection in India and it will present radiologically from nodules with branching lines called as ‘tree in bud’ to consolidations. Radiological presentations in various chronic lung diseases are overlapping and microbiological confirmation is must rather than giving empirical ant-tuberculosis treatment. Melioidosis is bacteriological infection causing similar clinical and radiological syndrome mimicking tuberculosis. In this case report, 70-year female presented with chronic respiratory illness with constitutional symptoms like cough, low grade fever, weight loss and anorexia and HRCT thorax imaging showing progressive pathologies as tree in bud to consolidations over 3 months duration. She had received anti-tuberculosis treatment empirically for 3 months and was having clinical and radiological deterioration. Bronchoscopy guided broncho-alveolar lavage (BAL) analysis for Gene Xpert MTB/RIF and Bacterial culture suggestive of Melioidosis as cause for her chronic respiratory illness. She was treated as per antibiotic protocol for Melioidosis and shown complete clinical and radiological response.
