Published: June 2024

Abstract

Since the most important issue in the production of digital currencies is energy consumption, the use of illegal electricity in mining farms has become very popular. Illegal mining is particularly important in countries such as Iran where the price of electrical energy is extremely low. This issue has caused numerous problems such as frequent blackouts, large losses for industries and even daily power cuts in several large cities. Previous machine learning approaches for miner detection are mostly supervised methods which rely on labeled data. Due to the fact that the number of labeled data is very limited in reality, we propose unsupervised methods in this paper. A real data set from Markazi Province Distribution Company in Iran has been employed to produce the results. The process consists of two stages: in the first stage, Dynamic Mode Decomposition (DMD) has been used to extract new features which compose the set of features along with certain factors from the Advanced Metering Infrastructure (AMI). These features are selected for 58 subscribers with positive and negative labels. In the second stage, a number of unsupervised models are built from the results of the first stage. The highest accuracy obtained is 74% from unsupervised algorithms and 85% for supervised algorithms, which is very significant considering the fact that unsupervised algorithms do not need labeled data.

Abstract

In low illumination environments, there are numerous challenges such as small targets, dense targets, occluded targets, and imbalanced sample distribution. Directly applying general object detection methods often fails to achieve ideal results. To address these challenges, this paper proposes an efficient object detection network, YOLO_LLD, for precise detection of targets in low illumination scenes. The algorithm is based on the YOLOv5s framework and introduces a cross-layer feature fusion method based on an information aggregation and distribution mechanism to mitigate information loss during cross-layer feature interactions. Additionally, the integration of dynamic sparse attention BiFormer constructs an efficient pyramid network architecture, reducing computational redundancy caused by the self-attention mechanism and enhancing the model's precision in detecting small targets.Inspired by the Inception structure, this paper designs the Multi-path Gradient Aggregation (MGA) structure, primarily aimed at ensuring better detail feature extraction from the perspective of gradient optimization under complex network models. Furthermore, a linear interval mapping mechanism is introduced into the bounding box regression loss function, enabling the network model to better focus on hard samples and further improve detection accuracy. Experimental results on the ExDark dataset demonstrate that, compared to YOLOv5, the mean average precision (mAP) is improved by 4.97%, indicating that the proposed method effectively enhances the performance of object detection in low illumination scenes.

Abstract

Purpose
To clarify the preferred timing and contents of early palliative care and preference for continued care delivery among patients with advanced cancer in Japan.
Methods
We conducted an Internet-based anonymous questionnaire survey on adult patients with advanced cancer. We assessed the patients’ wishes for palliative care delivered by a team or at outpatient clinics while asymptomatic, as well as the preferred intervention timing and preference for continuing care lifelong. Palliative care contents, cancer status, understanding and goals of cancer treatment, symptoms, and background factors were compared among these three preferences.
Results
In total, 531 patients responded (mean age, 61 years; men, 70%; major primary cancer sites, urological tract and breast), of whom 345 patients (65%) wished for palliative care while asymptomatic, and multivariate analysis revealed that a desire to address daily living and financial issues; wishing for consultations regarding illness, treatment, and end-of-life care; young age; primary sites other than hematological or urological sites; and increased physical distress were significantly associated with this wish. Approximately 51.3% of patients preferred palliative care before completing cancer treatment, while 40% preferred continuing palliative care lifelong. Young patients preferred early palliative care, and patients with a desire to address social distress preferred continuing palliative care.
Conclusion
The results highlight the importance of early palliative care planning in patients with advanced cancer; however, evaluating the eligibility for palliative care is essential.
Optimizing Load Parameters for Resisted Sled Sprint Training on Artificial Turf through Biomechanical and Kinematic Analysis in Soccer Players
Authors: Guo Tianze , Zhai Haiting , Wei Hongwen 
Published: June 2024

Abstract

Background: Resisted Sled Sprint (RSS) training is widely used to enhance sprinting speed across various sports by applying external loads to stimulate the lower limbs. This study investigates the optimal load for RSS by examining biomechanical and kinematic responses in soccer players to different load levels, focusing on how external loads affect sprint velocity and performance dynamics.
Methods: Twenty-nine soccer players participated in a controlled experiment involving five 20-meter sprints under varying load conditions
Results: A linear regression showed a significant relationship between load and sprint velocity decrease (%Body mass = 1.222 × %Vdec + 5.8, R² = 0.612). Increased loads led to reduced stride length and sprint speed but enhanced contact time, propulsive duration, vertical impulse, and ankle dorsiflexion. Notably, the 10%Vdec condition significantly increased propulsion impulse.
Conclusions: On artificial turf, external load strongly correlates with reduced sprint velocity in 20m resisted sled sprints. Higher loads improve ankle dorsiflexion and trunk tilt, facilitating horizontal force during acceleration. Although a 10% speed reduction minimally affects stride length and joint angles, it significantly boosts horizontal extensor force in soccer players.

Abstract

Polymorphism studies were conducted on elacestrant dihydrochloride (RAD1901-2HCl) to identify the existence of hydrates, solvates, and non-solvated forms and investigate their solid-state properties and relative thermodynamic stabilities. Two batches (denoted Form 1 and Form 2/3) of elacestrant dihydrochloride were extensively characterized, revealing that Form 1 exists as a stable anhydrous polymorphic form at 0-90% RH but converts irreversibly to a hydrate (Form 3) at greater than 90% RH. In contrast, Form 2/3 exhibits lower stability and is a dynamic mixture of anhydrous (Form 2) and hydrated states (Form 3) influenced by ambient RH. Analyzing humidity behavior, utilizing custom GVS and variable humidity XRPD methods, found that Form 1 is the preferred crystalline form, with stable properties and low hygroscopicity. Comprehensive polymorph screens, including heating, cooling, evaporation, and maturation cycles in diverse solvent systems, produced the known crystalline forms (Forms 1, 2, and 3). The prevalence of anhydrous Form 1 suggests its suitability for development, while the hydrate (Form 3) is generated in the presence of water or water/solvent mixtures. Water activity experiments with elacestrant dihydrochloride recrystallization solvents indicate that anhydrous Form 1 can be reliably obtained at and below 5% v/v water. These studies demonstrate that Form 1 (‘desired form’) is stable, has low hygroscopicity and good thermal properties, and is the most appropriate crystalline form for development and commercialization. However, careful control of water content (below 5% v/v) and room humidity is crucial during drug development, commercialization and storage to prevent the formation of the less stable Form 3 (hydrate).
Estilhaços do discurso amoroso na ficção histórica decolonial de Maryse Condé
Authors: Silva Ribeiro Maria Aparecida 
Published: June 2024

O texto analisa o romance Eu, Tituba, bruxa negra de Salém, de Maryse Condé, segundo elementos semânticos presentes na narração, os quais, por um lado, a aproximam de um padrão narrativo clássico e, por outro, trazem componentes singulares relacionados a determinado ponto de vista de que se vale o relato. Pontua, no texto, episódios nos quais a protagonista vivencia o amor, aqui entendido como pulsão afetiva que enseja determinadas atitudes nas diferentes interações sociais. Enquanto formulação literário-discursiva, tal noção aparece estilhaçada em situações constituintes de sua jornada. Fragmentação essa que parece indicar as intensas contradições emocionais vividas por Tituba, seus conflitos internos, frutos de sua condição de mulher, afrodescendente, sobrevivendo em uma sociedade colonial, escravista e patriarcal. O que torna o estudo de bell hooks, Tudo sobre o amor: novas perspectivas, essencial para entender tais processos de superação e de resiliência na decisão de amar e ser amada, conforme manifesta por Tituba, em meio a um atribulado percurso existencial. A contribuição de Roland Barthes, em Fragmentos de um Discurso Amoroso, corresponde à seleção de indicadores semânticos do desenvolvimento do tema-assunto, sugerindo, outrossim, caminhos interpretativos para tais índices, presentes no romance em estudo bem como na literatura canônica universal, conforme farta documentação do semiólogo francês. Como roteiro metodológico, são utilizadas as abordagens sugeridas por Abrams (2010), a saber, expressiva, mimética, objetiva e pragmática, que relacionam os tópicos pontuados na obra de Condé, respectivamente, a dados biográficos da autora; contextuais em relação à história narrada; estruturais; bem como aos usos que a narrativa tem ensejado na discussão sobre diáspora africana, feminismo negro e decolonialidade. E, por fim, destacam-se aspectos relevantes para a percepção da obra da escritora guadalupense como essencial ao estudo da formação das sociedades, a partir de uma lógica contra-hegemônica e em meio a processos antirracistas de revisão histórica.

Published: June 2024

Background
The emergence of the COVID-19 pandemic rapidly accelerated the need and implementation of digital innovations, especially in medicine.

Objective
To gain a better understanding of the stress associated with digital transformation in physicians, this study aims to identify working conditions that are stress relevant for physicians and differ in dependence on digital transformation. In addition, we examined the potential role of individual characteristics (ie, age, gender, and actual implementation of a digital innovation within the last 3 years) in digitalization-associated differences in these working conditions.

Methods
Cross-sectional web-based questionnaire data of 268 physicians (mean age 40.9, SD 12.3 y; n=150, 56% women) in Germany were analyzed. Physicians rated their chronic stress level and 11 relevant working conditions (ie, work stressors such as time pressure and work resources such as influence on sequence) both before and after either a fictional or real implementation of a relevant digital transformation at their workplace. In addition, a subsample of individuals (60; n=33, 55% women) submitted self-collected hair samples for cortisol analysis.

Results
The stress relevance of the selected working conditions was confirmed by significant correlations with self-rated chronic stress and hair cortisol levels (hair F) within the sample, all of them in the expected direction (P values between .01 and <.001). Multilevel modeling revealed significant differences associated with digital transformation in the rating of 8 (73%) out of 11 working conditions. More precisely, digital transformation was associated with potentially stress-enhancing effects in 6 working conditions (ie, influence on procedures and complexity of tasks) and stress-reducing effects in 2 other working conditions (ie, perceived workload and time pressure). Younger individuals, women, and individuals whose workplaces have implemented digital innovations tended to perceive digitalization-related differences in working conditions as rather stress-reducing.

Conclusions
Our study lays the foundation for future hypothesis-based longitudinal research by identifying those working conditions that are stress relevant for physicians and prone to differ as a function of digital transformation and individual characteristics.

Published: June 2024

We conducted a scoping review to 1) map and categorize published studies reporting interventions during the in vitro production of Bovine embryos and 2) qualitatively summarize the effects of treatments based on hormones, growth factors, sera, and reproductive fluids during oocyte maturation and embryo development. We searched electronic databases using keywords ('Bovine', 'embryo', 'blastocyst', 'oocyte', 'in vitro', 'quality') derived from the PIOS approach of the PRISMA statement. We identified 231 studies published during 2000−2021, with 133 being published between 2012 and 2021. The 231 studies were classified into four treatment categories: culture conditions (28), medium composition (45), bioactive supplements (79), and other additives (79), with 19 subcategories within these categories. A total of 77 studies included hormones, growth factors, sera, and reproductive fluids, among which 53 studies reported a positive effect on embryo production. Hormone-based treatments using melatonin, gonadotropins, and steroids were the most effective, followed by interventions assessing growth factors such as EGF, FGF, IGF-1, and BMP. These treatments improved oocyte competence, cytoplasmic/nuclear maturation, oocyte quality, and blastocyst development. Although free-serum media and synthetic/alternative products can partially or totally replace serum, it is sometimes necessary even at low concentrations. At high concentrations, hormones or growth factors may have detrimental effects on oocyte nuclear maturation, impair embryo development, and decrease embryo survival. Further meta-analyses are needed to estimate the intervention-specific effects. Future research should focus on interventions that have a positive effect and can be used extensively for Bovine production.
Fire and Climate: Connecting the Dots in British Columbia News Media
Authors: Earle Heather , Gunster Shane 
Published: June 2024

Background: Extreme weather events are intensifying with climate change, offering opportunities to raise the public urgency of this issue. The media’s role in communicating this connection is crucial. Analysis: This article analyzes media coverage of wildfires over a nine-year period in British Columbia focusing on how they are linked to climate change, in particular, during the 2017 and 2018 record-breaking fire seasons. Conclusion and implications: In media coverage in British Columbia, there is a marked absence of a link between climate change and wildfires and a tendency for connections to be tokenistic, decontextualized, and normalizing. More provocative narratives developed by various public figures that locate wildfires within broader narratives of climate crisis offer more compelling accounts.
Strain localization and deformation mechanisms in melt-/fluid-bearing UHP eclogites: Implications for exhumation dynamics
Authors: Chen Zhe , Wang Lu , Brown Michael , Johnson Tim E. 
Published: June 2024

Melt/fluid evolution processes are important in determining the
rheological behavior of lithosphere subducted to and exhumed from
ultrahigh-pressure (UHP), controlling the flow of lithospheric material,
the generation of melts from the upper mantle, and potentially
contributing to magmatism and growth of the continental crust. In these
circumstances, determining the controls on deformation mechanisms of
deeply subducted eclogite is crucial to understanding exhumation
dynamics of UHP terranes. However, few studies are reported on the
multi-stage evolution of microstructures in natural eclogites exhumed
along the same retrograde P-T-t path, particularly in the
presence of supercritical fluid or melt.
Recently, evidence of melt-fluid events within UHP eclogite has been
reported from the Sulu belt, China. The eclogite was deformed by
multiple stages of folding associated with two phases of melt/fluid
evolution during exhumation: Dehydroxylation of nominally anhydrous
minerals produced a supercritical fluid in the early stage of exhumation
from UHP conditions, and then, omphacite-breakdown melting during the
late stage of exhumation from HP conditions.
Here, we present a microstructural analysis of UHP eclogite from
different structural zones in single outcrops from Yangkou and Taohang,
in the Sulu belt. These eclogites preserve assemblages formed at
different metamorphic stages controlled by strain partitioning or
located in same structural position but affected by different degrees of
melt/fluid modification. Results show that deformation mechanisms switch
from overall brittle to ductile with increased melt/fluid mobility.
Omphacite fabrics change from S to L type, corresponding to progressive
enhancement of strain associated with melt/fluid migration from early
fold hinges, to fold limbs and then to strain-localized shear zones.
We conclude that strain partitioning and inherited HO
content of UHP rocks control fluid distribution, and influence
subsequent microfabrics, deformation mechanisms, partial melting, and
retrogression at different structural locations during exhumation. These
variations can play critical roles in reducing strength of eclogite and
thus contribute to rheological heterogeneities in convergent settings at
UHP conditions, potentially enhancing exhumation.
Nature prescribing: emerging insights about reconciliation-based and culturally inclusive approaches from a tricultural community health centre
Authors: Vaillancourt Anita , Barnstaple Rebecca , Robitaille Natalie , Williams Taylor 
Published: June 2024

Abstract

This commentary highlights the importance of social and nature prescribing programs reflecting culturally diverse perspectives and practices. Creating and holding space for Indigenous and other worldviews should be a key priority of nature prescribing, a relatively recent practice in Canada that recognizes and promotes health benefits associated with engaging in a variety of activities in natural settings. Central to designing and delivering nature prescribing that is culturally inclusive and grounded in fulfilling obligations of reconciliation is recognizing the ongoing dominance of Western worldviews and their associated implications for decolonizing and Indigenizing nature-based programming. Consciously working to expand Western values, with the aim of extending nature prescribing practices beyond mere nature exposure to fostering emotional connections to nature, is a critically important part of the ongoing development of nature-based interventions and nature prescribing.
