Abstract
The stability of the mine construction is significantly impacted by weathered granite (WG), which presents a significant risk to the security of workers and equipment. In order to investigate the strength characteristics of WG under different confining pressures, acoustic emission (AE) and scanning electron microscopy (SEM) tests were performed on WG under triaxial compression. The relationship between strength evolution and different confining pressures of WG is studied. Under various confining pressures, the variation regularity of the AE parameters of rock samples was examined. Additionally, the microscopic morphology of rock samples is investigated using SEM. The results show that increased confining pressure suppresses WG damage development before the stress peak and switches to promoting damage development following the stress peak. The axial strength is quantitatively analyzed before the WG stress peak using the Hoek-Brown failure criterion, and the axial damage threshold stress under different confining pressures is obtained. Furthermore, the axial damage threshold stress point is clearly increased in the AE ring count rate and energy rate curves of WG at various confining pressures. The last effect of water on WG is microstructural weakening, which manifests itself in the swelling and erosion of the structure by water.
Fatigue Crack Growth on Several Materials under Single-Spike Overloads and Aircraft Spectra during Constraint-Loss Behavior
Authors: Newman James C. , Walker Kevin F. 
Published: January 2024

Abstract
The phenomenon of flat-to-slant crack growth has been studied by many in the fracture mechanics community. At low stress-intensity factors, a fatigue-crack surface is flat (tensile mode) and the crack-front region is under plane-strain conditions (high constraint). As the crack grows with higher stress-intensity factors, a 45° shear lip occurs through the thickness of the sheet or plate. This behavior is the shear mode, which is under low constraint or plane-stress conditions. In 1966, Schijve found that the transition from flat-to-slant crack growth on a 2024-T3 Alclad aluminum alloy over a wide range in stress ratios (R) occurred at a “constant” crack-growth rate. Also, Newman and Hudson showed the same behavior on 7075-Temper-6 and Ti–8Al–1Mo–1V alloys, validating Schijve’s observation that crack-growth rate was the key parameter for flat-to-slant crack-growth behavior. The materials considered herein are 2024-T3, 7075-T6, and 9310 steel. Crack-growth behavior during single-spike overloads and simulated aircraft spectrum loading are presented. The fatigue structural analysis (FASTRAN) crack-closure based life-prediction code was used to correlate the constant-amplitude (CA) crack-growth-rate data over a wide range in stress ratios (R = Smin/Smax) and rates from threshold to near fracture, and to calculate or predict the crack-growth behavior on single-spike overload tests. Crack-closure behavior is strongly dependent upon the level of constraint. The main objective was to see if the constraint-loss region is the primary reason for crack-growth delays after single-spike overloads. Also, crack-growth analyses are presented on tests that were conducted by Wanhill on 2024-T3 Alclad aluminum alloy under the transport wing standard (TWIST) spectrum. Crack-growth analyses using crack-closure theory without constraint loss was “unable” to predict crack growth under spike overloads or simulated aircraft spectra. However, predicted crack length against cycles with constraint-loss behavior compared reasonably well with all tests.
Predictive brain activity shows congruent semantic specificity in language comprehension and production.

Sentence fragments strongly predicting a specific subsequent meaningful word elicit larger pre-word slow waves, Prediction Potentials (PP), than unpredictive contexts. To test current predictive processing models, 128-channel EEG data was collected from both sexes to examine whether (i) different semantic PPs are elicited in language comprehension and production, and (ii) whether these PPs originate from the same specific ‘prediction area(s)’ or rather from widely-distributed category-specific neuronal circuits reflecting the meaning of the predicted item. Larger slow waves after predictable than unpredictable contexts were present both before subjects heard the sentence-final word in the comprehension experiment and before they pronounced the sentence-final word in the production experiment. Crucially, cortical sources underlying the semantic PP were distributed across several cortical areas and differed between the semantic categories of the expected words. In both production and comprehension, anticipation of animal words was reflected by sources in posterior visual areas, whereas predictable tool words were preceded by sources in frontocentral sensorimotor cortex. For both modalities, PP size increased with higher cloze probability, thus further confirming that semantic predictions are reflected, and with shorter latencies with which participants completed sentence fragments. These results sit comfortably with theories viewing distributed semantic-category-specific circuits as the mechanistic basis of semantic prediction in the two modalities.Significant statementWe report larger anticipatory negative-going Prediction Potentials (PPs) after sentence fragments with predictable than unpredictable endings both during language comprehension and production. In production and comprehension experiments, PP topographies resembled each other but, for each modality, PPs differed in the same way between semantic categories of the predictable words. Likewise, cortical source estimation revealed similar prediction-related cortical activations across modalities but consistent activation differences reflecting the meaning of predicted symbols. Furthermore, PP size was linked with behavioural measures of predictability (Cloze probability) and ease of processing (Reaction Times) and correlated PPs were seen in production and comprehension; these observations are consistent with similar prediction mechanisms across modalities but different ones for semantic types.

Published: January 2024

A agressão sexual é um fenômeno que historicamente atravessa a humanidade com níveis diferenciados de complexidade. Esta pesquisa, de abordagem qualitativa, objetiva realizar a caracterização biopsicossocial do jovem autor de agressão sexual, a partir da descrição de experiências adversas na infância e fatores de risco. O método de análise consistiu em estudo de casos múltiplos, pelo qual são descritas e comparadas as trajetórias de autores de atos infracionais, sendo três referentes à violência sexual contra vítimas adultas e mais três com infrações de outra natureza. O procedimento incluiu a análise de processos jurídicos que envolviam jovens entre 15 e 18 anos, os quais cumpriam medida socioeducativa no estado do Pará no período pesquisado, além de entrevistas guiadas por um roteiro adaptado para autores de agressão sexual, e um questionário internacional de experiências adversas na infância. Os seis jovens vivenciaram em suas trajetórias experiências de negligência e violência múltiplas. Há experiências vivenciadas na infância apenas pelos autores de violência sexual, como negligência emocional, ausência de um dos genitores, além de abuso físico e emocional. Outras experiências foram comuns às trajetórias estudadas. A importância deste estudo está no auxílio à compreensão contextualizada da violência sexual e subsídios ao desenvolvimento de políticas, com o propósito de assistir essa população exposta à vulnerabilidade social e diferentes formas de violência desde a infância.
Феномен доверия к себе в человекоцентрированном подходе К. Роджерса
Authors: Бабанов Алексей Вячеславович 
Published: January 2024

<p>В статье проанализированы понятие и модель доверия к себе Т. П. Скрипкиной. Отталкиваясь от этого анализа, автор интерпретирует феномен доверия к себе в человекоцентрированном подходе и персонологии Е. Б. Старовойтенко. Для человекоцентрированного подхода К. Роджерса доверие к себе есть опора на свой организмический ценностный процесс. Личность может находиться в состоянии противоречия, когда представления о себе (Я-концепция) оказываются важнее и безопаснее для осознания, чем непосредственный организмический опыт. В таком случае потребности и ценности «Я» могут заблокировать организмический процесс ценения, отделить человека от собственной жизненной основы.</p><p>Решение данного практического противоречия состоит в изменении Я-концепции, в приведении ее в соответствие с организмическим ценностным процессом, т. е. в обретении человеком своей целостности. В персонологической модели рефлексивного отношения личности к себе «Я» понимается как субъект рефлексии, в процессе которой «Я» обнаруживает, что себя не знает. Есть «Я-неизвестное», в котором и заключено противоречие доверия к себе: как личность может чувствовать самоценность и надежность внутреннего опыта самой себя, если она мультисубъектна — если есть части ее, которые она не знает и которые недоступны для осознания.</p><p>Решение противоречия тоже практическое: оно заключается в интеграции, в достижении личностью своей целостности. Однако эти целостности имеют разные философские основания — различные идеи субъектности. В человекоцентрированном подходе субъектность человека — это целостность организмического процесса, сознания и гибкой Я-концепции, что говорит об идеи процессуальности личности, а в персонологической модели — целостность субъекта рефлексии (Я-известного и Я-неизвестного), что говорит об идеи субстанциальности личности. Процессуальность субъектности в холистическом подходе К. Роджерса была нами подсвечена с помощью идеи интуиции А. Бергсона.</p>

Coronavirus disease 2019 (COVID-19) can cause systemic and respiratory symptoms. Acute respiratory distress syndrome (ARDS), anemia, acute heart injury, secondary infection, and stroke are the complications of COVID-19. Age, oxidative stress, endothelial dysfunction, inflammatory status, vascular risk factors, and hypoxemia are risk factors for stroke associated with COVID-19. In this case report, two cases of COVID-19 complicated by stroke and other thromboembolic diseases were discussed. Case 1: a 46-year-old man presented with right extremities weakness, dysarthria, cough, colds, chest pain radiating to left upper extremity. He was diagnosed with moderate COVID-19, with complication of embolic stroke and myocardial infarction. After administration of IV furosemid and recombinant tissue plasminogen activator (rTPA), his condition improved, and he was discharged from our facility. Case 2: a 54-year-old woman presented with a decreased level of consciousness, skin discoloration, tenderness on her left calf, cough, fever, and shortness of breath. She was diagnosed with moderate COVID-19 with a complication of thrombotic stoke and deep vein thrombosis (DVT). She was treated with rTPA, IV citicoline, and fondaparinux for 5 days. In conclusion, COVID-19 carries a risk of thromboembolic complication. COVID-19 patients have a higher risk of bleeding, therefore, medications, particularly anticoagulant, should be administered with more caution.

Published: January 2024

This paper describes design of experimental methodology developed to measure the working properties of accuracy of the path traversed by a collaborative robot. The methodology proposed here uses a collaborative robot and a laser measuring system Gepard from Raytec. The main parts of the measuring chain and the ISO 9283 standard are described. The proposed experimental methodology should examine working properties of industrial robots, such as the properties of position and path. The focus of this paper lies on the path accuracy of robots. Currently, the interest in this topic is on the rise and the measuring systems capable of recording this parameter are too costly. This paper focuses on experimental measuring of the path properties, describing them in more detail. The measuring and results were processed in the software tool developed for Gepard.
Encuadrar la representación: discursos sobre mujeres árabes musulmanas en documentales diásporicos en España
Authors: Ventura Kessel Ivyliet 
Published: January 2024

Este artículo evalúa la manera en que se representan a mujeres árabes musulmanas en documentales de cineastas diaspóricos y productoras implicadas en la transformación social y en dar visibilidad a individuos/as habitualmente excluidos/as de las narrativas tradicionales. A partir de los casos de estudio Entre dos orillas, voces de mujeres marroquíes (Hicham Malayo, 2014) y Vidas invisibles: mujeres migrantes bajo el plástico (La Cosecha Producción Audiovisual, 2020) se realizó un análisis de contenido cualitativo que examinó los mensajes sobre estas mujeres y su vida en España, y los dispositivos de encuadre utilizados en los documentales. Aunque estos audiovisuales intentan retratar la diversidad de experiencias de las mujeres inmigrantes árabes musulmanas en lugar de presentar una imagen homogénea y universal, siguen la narrativa común que retrata a inmigrantes como una adición externa a la sociedad española, más que como miembros plenos de la misma. Esto sugiere que, aunque estas obras provengan de márgenes dentro de la producción industrial, no necesariamente ofrecen una alternativa discursiva rompedora respecto a estos colectivos. Tampoco proporcionan una representación de estas mujeres que contribuya a (re)definir su identidad colectiva como parte de la sociedad española, ni permiten comprender a España como un lugar de diversidad étnica y social.
Development and validation of a GMAW arc model

Published: January 2024

Abstract
Gas metal arc welding has become a widely used process in industrial applications. Numerical simulations can be used to investigate and optimize this process. Due to the multi-component plasma in GMAW and the associated physical properties, the modelling of the arc plays a central role.
Therefore, in the context of this publication, Hertel's existing arc model has been further developed. In order to increase the self-consistency and thus the versatility of the model, the assumptions used were reduced. To this end, experiments were first conducted with varying experimental parameters. The data obtained from these experiments were used to further validate the model. The model was then developed for a spray arc.
Finally, the experimental data were compared with the numerical simulation results of the developed model. Very good agreement was found with respect to the arc power and the voltage drop across the arc.

Abstract

Fischer plots find extensive applications in paleoenvironmental studies as visual depictions of sea and lake-level fluctuations. They graphically represent the linearly adjusted alterations in the cumulative thickness of sedimentary cycles in a specific geographical region over time, with respect to either the cycle number or the depth of the sedimentary strata. The observed cycles represent successive intervals of sediment deposition and erosion, that are driven by fluctuations in the rates of subsidence of the sea level. Previous researchers have introduced various applications for constructing Fischer plots. However, this study focuses on comparing Fischer plot analyses performed in the Cambrian Machinchang Formation, Langkawi, using three different approaches: 1) the Excel platform, 2) the Fischerlab application, and 3) the Python code "PyFISCHERPLOT". The Excel platform offers a convenient and accessible approach to generating Fisher plots using spreadsheet software. On the other hand, the Python code "PyFISCHERPLOT" provides a computational solution for creating Fisher plots using Python programming. In this study, the results obtained from all platforms are compared, and the comparison includes evaluating the accuracy, efficiency, and flexibility of the two approaches. By assessing the strengths and limitations of each platform, this research aims to provide researchers with insights into selecting the appropriate tool for their Fisher plot analysis needs. The results indicate that Cambrian relative sea-level fluctuations display third-order patterns, featuring prolonged sea-level rise and fall intervals spanning around 0.5 to 3 million years. The sea fluctuation trends of the Machinchang Formation are then correlated with existing sea-level curves from the global Cambrian record. The comparison demonstrates a notable synchronicity, thereby successfully contributing to our understanding of the broader-scale processes that influenced sea level changes during the Cambrian period. Additionally, these findings shed light on the paleoenvironmental evolution of the Machinchang Formation within a global context.

Abstract

The ambiguity about whether the histidine-rich calcium-binding protein-coding gene (HisR) or the pore-forming toxin-like gene (PFT) or both are responsible for wheat Fusarium head blight (FHB) resistance conferred by Fhb1 QTL hinders wheat improvement and resistance mechanism elucidation. Here, with a series of developed lines possessing HisR but varying in PFT presence and five HisR-carrying PFT mutant lines created via gene editing, we show that PFT does not confer FHB resistance and the HisR resistance effect does not require PFT. We also show that PFT is not associated with morphological and phenological characters that often affect FHB severity.
Regional Bias in Monolingual English Language Models

Published: January 2024

Abstract
In Natural Language Processing (NLP), pre-trained language models (LLMs) are widely employed and refined for various tasks. These models have shown considerable social and geographic biases creating skewed or even unfair representations of certain groups.Research focuses on biases toward L2 (English as a second language) regions but neglects bias within L1 (first language) regions.In this work, we ask if there is regional bias within L1 regions already inherent in pre-trained LLMs and, if so, what the consequences are in terms of downstream model performance.We contribute an investigation framework specifically tailored for low-resource regions, offering a method to identify bias without imposing strict requirements for labeled datasets. Our research reveals subtle geographic variations in the word embeddings of BERT, even in cultures traditionally perceived as similar. These nuanced features, once captured, have the potential to significantly impact downstream tasks. Generally, models exhibit comparable performance on datasets that share similarities, and conversely, performance may diverge when datasets differ in their nuanced features embedded within the language. It is crucial to note that estimating model performance solely based on standard benchmark datasets may not necessarily apply to the datasets with distinct features from the benchmark datasets. Our proposed framework plays a pivotal role in identifying and addressing biases detected in word embeddings, particularly evident in low-resource regions such as New Zealand.
Phonon collapse and anharmonic melting of the 3D charge-density wave in kagome metals

Published: January 2024

Abstract

The charge-density wave (CDW) mechanism and resulting structure of the AV3Sb5 family of kagome metals has posed a puzzling challenge since their discovery four years ago. In fact, the lack of consensus on the origin and structure of the CDW hinders the understanding of the emerging phenomena. Here, by employing a non-perturbative treatment of anharmonicity from first-principles calculations, we reveal that the charge-density transition in CsV3Sb5 is driven by the large electron-phonon coupling of the material and that the melting of the CDW state is attributed to ionic entropy and lattice anharmonicity. The calculated transition temperature is in very good agreement with experiments, implying that soft mode physics are at the core of the charge-density wave transition. Contrary to the standard assumption associated with a pure kagome lattice, the CDW is essentially three-dimensional as it is triggered by an unstable phonon at the L point. The absence of involvement of phonons at the M point enables us to constrain the resulting symmetries to six possible space groups. The unusually large electron-phonon linewidth of the soft mode explains why inelastic scattering experiments did not observe any softened phonon. We foresee that large anharmonic effects are ubiquitous and could be fundamental to understand the observed phenomena also in other kagome families.
