TL;DR: Investigation of the association between hours of working alone and poor menstrual health among 740 cosmetics saleswomen in South Korea found women who worked alone for 3 h or more in a day reported a higher prevalence of ever being unable to change the sanitary pads.
Abstract: Menstrual hygiene management (MHM) at work has been neglected in occupational health research despite its importance for female workers’ health. This study investigated the association between hours of working alone and poor menstrual health among 740 cosmetics saleswomen in South Korea. Hours of working alone in a day were classified into 4 categories. MHM was measured by asking “Over the past six months, have you ever experienced that you could not change your sanitary pad when you need to change it at work?” We also measured the experience of dermatopathy due to unchanged sanitary pads. Cosmetics saleswomen who worked alone for 3 h or more in a day reported a higher prevalence of ever being unable to change the sanitary pads (prevalence ratio [PR] 1.84, 95% confidence interval [CI]: 1.37–2.46) and dermatopathy due to unchanged sanitary pads (PR 2.06, 95% CI: 1.18–3.59) than those who worked alone less than 1 h in a day.

TL;DR: Preliminary evidence is reported suggesting that, despite obvious implementational differences in how people and TLMs learn and use language, TLMs can be used to identify individual differences in human fluency task behaviors better than existing computational models, and may offer insights into human memory retrieval strategies.
Abstract: Can deep language models be explanatory models of human cognition? If so, what are their limits? In order to explore this question, we propose an approach called hyperparameter hypothesization that uses predictive hyperparameter tuning in order to find individuating descriptors of cognitive-behavioral profiles. We take the first step in this approach by predicting human performance in the semantic fluency task (SFT), a well-studied task in cognitive science that has never before been modeled using transformer-based language models (TLMs). In our task setup, we compare several approaches to predicting which word an individual performing SFT will utter next. We report preliminary evidence suggesting that, despite obvious implementational differences in how people and TLMs learn and use language, TLMs can be used to identify individual differences in human fluency task behaviors better than existing computational models, and may offer insights into human memory retrieval strategies -- cognitive process not typically considered to be the kinds of things TLMs can model. Finally, we discuss the implications of this work for cognitive modeling of knowledge representations.

TL;DR: In this article , the authors discuss the Trump administration's foreign policy with its isolationist character and point out that, given the relative weakening of US international influence, the loss of US manufacturing and the decline in people's living standards, and Trump's mercantilist overtones, the US administration has changed its long-held liberal internationalist diplomatic course in favour of a partial return to traditional isolationism.
Abstract: Since taking office, Trump has adhered to the policy tenet of America First, with unilateralism as the course of action. At the same time, the Trump administration is also deliberately reducing the international responsibilities borne by the US and emphasizing the principles of fairness and transaction in foreign dealings. Some scholars see this series of actions as a trend towards a return to isolationism. This paper revolves around isolationist foreign policy, more focuses on the revival of isolationism since the Trump administration took office, discusses the Trump administration's foreign policy with its isolationist character. This paper further points out that, given the relative weakening of US international influence, the loss of US manufacturing and the decline in people's living standards, and Trump's mercantilist overtones, the Trump administration has changed its long-held liberal internationalist diplomatic course in favour of a partial return to traditional isolationism. It has profoundly affected the US domestic and world landscape. This study can help to understand the shift in the guiding philosophy of US diplomacy and provide background information on how to develop relations with the US in the new context.

TL;DR: Positron emission tomography (PET) and single-photon emission computed tomography as mentioned in this paper are two primary modalities for myocardial perfusion imaging, which can measure the universal burden of ischemic heart disease (IHD).
Abstract: Coronary artery disease (CAD) is an important cause of morbidity and mortality worldwide. Perfusion abnormalities precede wall motion abnormalities, ECG changes, and angina in the etiology of CAD. myocardial perfusion imaging (MPI) can detect perfusion alterations due to pathology at sites such as the endothelium, microvasculature, and epicardial coronary arteries. Thus, it measures the universal burden of ischemic heart disease (IHD). Nuclear medicine MPI is an important noninvasive imaging modality to evaluate the perfusion of the myocardium. Positron Emission Tomography (PET) and single-photon emission computed tomography (SPECT) with or without computed tomography (CT) are 2 primary modalities. PET is a highly sensitive modality with an inherent ability to quantify absolute myocardial blood flow (MBF) and variations in MBF due to various stress agents. PET has immense potential to change clinical management, prognosticate, and risk stratify patients presenting with clinical or preclinical CAD. Evidence shows that early PET detection of myocardial perfusion abnormalities, followed by aggressive intervention for cardiovascular risk factors, can reinstate myocardial perfusion. This may reduce morbidity and mortality. We shall be reviewing the clinical impact of PET in CAD and preclinical CAD patients.

TL;DR: In this article, the magnetic wall across each nonradiating edge has been transformed into a composite boundary and unlike the earlier designs, this mechanism has been successfully demonstrated in eliminating the cross-polarized (XP) fields without causing any harm to the primary resonance.
Abstract: Discrimination of a higher order TM02 mode in a rectangular patch by minimally tampering its boundary condition has been addressed based on some insightful studies. The magnetic wall across each nonradiating edge has been transformed into a composite boundary and unlike the earlier designs, this mechanism has been successfully demonstrated in eliminating the cross-polarized (XP) fields without causing any harm to the primary resonance. The signature of modal discrimination has been experimentally evidenced in the $X$ -band by reducing the H-plane XP level consistently over the full range of elevation angle varying over 15–18 dB. Such “full-elevation” feature is highly significant from practical aspect and not commonly achievable in the other known methods. The proposed technique is directly integratable with a practical system without imposing any constraint on its deployment platform.

TL;DR: In this paper, a strategic metal pole has been introduced to control the modal current of an orthogonal higher mode (TM02) but leaving the fundamental radiating mode untouched, and the pole height can be reduced by 40% −63% by accepting a tradeoff in XP suppression by 3 dB.
Abstract: This letter explores a new concept for the first time to control a specific unwanted higher mode in a microstrip patch with a target to reduce its cross-polarized (XP) radiation over the orthogonal plane. A strategic metal pole has been introduced to control the modal current of an orthogonal higher mode (TM02) but leaving the fundamental radiating mode (TM10) untouched. The conjecture has been successfully verified in S -band. The approach is the simplest of all explored earlier, requiring no multiparameter optimization or fabrication complexity except requiring an additional vertical space. Antenna impedance and primary radiations are insensitive to this technique but it ensures 11dB XP suppression over the orthogonal plane. The pole height can be reduced by 40%–63% by accepting a tradeoff in XP suppression by 3 dB.

TL;DR: In this article, the authors proposed a DGS-based solution to the problem of excess backside radiation caused by the cross-polarized (XP) fields, which is being faced by all defected ground structure (DGS) integrated patches.
Abstract: This letter addresses a practical issue of excess backside radiation caused by the cross-polarized (XP) fields, which is being faced by all defected ground structure (DGS) integrated patches. Defects or slots on the ground plane (GP) suppresses the H -plane XP fields. These strategic slots cause leakage of XP fields toward the backside of the antenna. This letter, for the first time, explores the physical insight behind this phenomenon with an aim to find a solution. Engineering on the backside of the GP has been conceived and systematically developed in the form of a pair of electric walls with varied geometries. Serrated comb-shaped geometry has been proposed finally. A thorough DGS-based design along with its experimental validation in the X -band ensures a reduction in XP radiation nearly by 10 dB in the backside maintaining its front-side reduction by 16–18 dB. This also reduces the usual backward radiation originated from the copolarized fields. Although the GP engineering makes the structure nonplanar, its advanced features may find potential applications where significantly low XP standalone antennas are required, such as wireless base stations, to onboard satellite systems.

TL;DR: In this paper, geometrical optics-based raytracing was combined with modal analysis to realize an open cavity structure as an advanced variant of the resonant cavity antenna (RCA).
Abstract: This letter explores geometrical optics-based raytracing in combination with modal analysis to realize an open cavity structure as an advanced variant of the resonant cavity antenna (RCA). Additional ray confinement has been ensured by determining accurate phase-locking conditions as demonstrated for the first time. Its combination with the analysis of the cavity mode has also been introduced to determine the optimum design parameters, achieving improved radiation properties. With respect to a reference RCA reported earlier, the proposed approach exhibits a remarkable improvement in gain by 4–9 dB, resulting in about 17 dBi peak value consistently over the full 18% matching bandwidth. This is resultant from an increase in aperture efficiency, typically from 27% to 74%. This is achieved without any compromise with the cross-polarization property. The sidelobe level improves over the band except in higher frequency in H-plane. The proposed concept is commercially viable, showing significantly advantageous features.

TL;DR: In this paper , the authors revisited the reasons behind the cross-polarized (XP) radiation in microstrip patches and focused on alleviating a long-standing deficiency in terms of a comprehensive knowledge about the same.
Abstract: This article revisits the reasons behind the cross-polarized (XP) radiation in microstrip patches and focuses on alleviating a long-standing deficiency in terms of a comprehensive knowledge about the same. This study has a twofold objective. First, it explores all possible components of the surface fields as the correlating factors over all of the radiation planes, especially across the diagonal or skewed axes. An extensive study involving varied patch geometries along with different feed networks has been executed. The resulting huge volume of data has been analyzed to identify the ideal surface field requirements for the best possible XP performance.
