Magnetic properties of Monoclinic Fe3Se4 doped with transition metals

We report density functional theory (DFT) study of the magnetic properties of Fe3Se4 doped with transition metals, TM (Co, Cr, Ni and Mn), where TM ions are doped in Fe sites to yield Fe<inf>3−x</inf>(TM)<inf>x</inf>Se<inf>4</inf> (x = 0.5). Screening of the exchange coupling interaction and magnetization modifications were performed upon the substitution of Fe by 3d-transition metals at various Fe sites in the Fe<inf>3</inf>Se<inf>4</inf> structure. Our study reveals that doping of Fe<inf>3</inf>Se<inf>4</inf> with 3d-elements at Fe sites does not remove antiferromagnetic (AFM) coupling across layers. Although a slight increase in magnetization can be obtained at low Ni-doping. The origin of this increase could be attributed to the AFM superexchange coupling of Fe across the Se planes. This coupling is exhibited by elements with more than half-filled electron shell, i.e. Fe is such an element. Moreover, the exchange coupling between layers of Fe increases strongly as function of interlayer spacing (a lattice parameter) for both pristine and TM-doped Fe<inf>3</inf>Se<inf>4</inf>, while the magnetizations of Fe<inf>3</inf>Se<inf>4</inf> alloys do not change significantly.
Semi-Analytical Non-Linear Physical Model of the Core Losses in Ferrite Ring Cores

To calculate ferrite core losses based on a physical approach, non-linear material effects must be considered. To implement these effects in a fast and accurate way, a new semi-analytical model is proposed. It combines the solution of the wave equations in the core with advanced material models of ferrite into an iterative procedure. The results validate the approach, which enables a fast calculation of the core losses.
KILLING TWO BIRDS WITH A STONE: MERGING READING AND WRITING ACTIVITIES THROUGH BLACKOUT POETRY

This study investigates students' perceptions of writing online blackout poetry in an elective course called Children's Literature. A descriptive case study is purposively used to explore their perceptions of the advantages of writing online blackout poetry on their reading and writing skills and the obstacles in doing the activity. Fifty-one students of children's literature writing blackout poetries are the research participants. Close-ended and open-ended questionnaires were used for the data collection. Meanwhile, the data were analyzed thematically using the framework of Braun and Clarke (2006). The findings show that students have a positive perception of writing blackout poetry. They believe that the activity is challenging and promotes their creativity. Furthermore, it is regarded as a media that merges reading and writing activities. However, it is found that blackout poetry has limited word expression. Despite its weaknesses, this study implies that blackout poetry can promote creativity and reading and writing activities in the EFL context.
Bias in the Estimation of Seismic Risk for Municipal Building Stocks Due to Limited Data

This study investigated the effect of the building data knowledge level on seismic risk estimation for municipal building stocks, focusing on identifying the characteristics that influence loss estimation bias. Fifteen municipalities in two Slovenian regions were analysed using twelve building data knowledge levels, defined by combining different knowledge levels about building location and floor area. The knowledge levels ranged from those using data aggregated at the municipality level to those using building-specific data. The bias was quantified as the log residual between the expected annual losses estimated for the given knowledge level and the base-case level, characterised by building-specific data. The results indicate that loss estimation bias is affected by both the building location and floor-area knowledge levels. The data on building density distribution across the municipality and building-class-specific floor areas are sufficient for estimating loss with low bias with respect to the base-case level. The effect of potential data improvement on bias reduction can be assessed using building stock homogeneity and hazard variation indexes determined from readily available data. Further research is needed to explore loss estimation bias for building data knowledge levels not considered in this study and generalise the concepts to other regions and building classifications.
Targeted Therapy for Cancers: From Ongoing Clinical Trials to FDA-Approved Drugs

The development of targeted therapies has revolutionized cancer treatment, offering improved efficacy with reduced side effects compared with traditional chemotherapy. This review highlights the current landscape of targeted therapy in lung cancer, colorectal cancer, and prostate cancer, focusing on key molecular targets. Moreover, it aligns with US Food and Drug Administration (FDA)-approved drugs and drug candidates. In lung cancer, mutations in the epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) gene rearrangements have emerged as significant targets. FDA-approved drugs like osimertinib and crizotinib specifically inhibit these aberrant pathways, providing remarkable benefits in patients with EGFR-mutated or ALK-positive lung cancer. Colorectal cancer treatment has been shaped by targeting the vascular endothelial growth factor (VEGF) and EGFR. Bevacizumab and cetuximab are prominent FDA-approved agents that hinder VEGF and EGFR signaling, significantly enhancing outcomes in metastatic colorectal cancer patients. In prostate cancer, androgen receptor (AR) targeting is pivotal. Drugs like enzalutamide, apalutamide, and darolutamide effectively inhibit AR signaling, demonstrating efficacy in castration-resistant prostate cancer. This review further highlights promising targets like mesenchymal-epithelial transition (MET), ROS1, BRAF, and poly(ADP-ribose) polymeras (PARP) in specific cancer subsets, along with ongoing clinical trials that continue to shape the future of targeted therapy.
Importance of preovulatory estradiol on uterine receptivity and luteal function

Abstract Animals that exhibited estrus had greater pregnancy success compared to animals that did not exhibit estrus before fixed-time AI (FTAI). Estradiol is synthesized in bovine ovarian follicles under gonadotropin regulation and can directly and indirectly regulate the uterine receptivity and luteal function. Estradiol concentrations at FTAI impacted oviductal gene expression and has been reported to play an important role in establishing the timing of uterine receptivity. These changes have been reported to impact uterine pH and sperm transport to the site of fertilization. After fertilization, preovulatory estradiol has been reported to improve embryo survival likely by mediating changes in uterine blood flow, endometrial thickness and changes in histotroph. Cows with greater estradiol concentrations at the time of GnRH-induced ovulation also had a larger dominant follicle size and greater circulating progesterone concentrations on day 7. Therefore, it is impossible to accurately determine the individual benefit of greater estradiol concentrations prior to ovulation and greater progesterone concentrations following ovulation to pregnancy establishment, as these two measurements are confounded. Research has indicated an importance in the occurrence and timing of increasing preovulatory concentrations of estradiol, but increasing estradiol concentrations by supplementation may not be sufficient to increase fertility. Increased production of estradiol by the preovulatory follicle may be required to enhance fertility through the regulation of sperm transport, fertilization, oviductal secretions, the uterine environment, and embryo survival.
Chemical Warfare in Colombia: The Costs of Coca Fumigation

While the US wages the 'War on Terror' in the Middle East, it is conducting a terror campaign of its own closer to home. Chemical spraying is being used in Colombia as a deterrent and to destroy 'illicit' coca crops. But most people growing coca are poor campesinos with no alternatives to make a living. Whole towns, rivers, livestock and legitimate food crops have been sprayed and livelihoods destroyed by these US-administered fumigation programmes, backed by the Colombian state. Herbicides such as Glyphosate and Cosmo Flux are being used in high concentrations and sprayed from low-flying planes. The effects of heavy exposure to these chemicals on humans is still unknown. As O'Shaughnessy reveals, fumigation doesn't just harm people - farmers' livestock are being killed, and much of the area sprayed is rainforest - a fragile environment rich in diversity that is being poisoned by chemicals. This path-breaking book of investigative journalism lifts the veil on fumigation: why is it really happening, and who benefits? O'Shaughnessy travels to the Putumayo and Bolivar departments of Colombia, where most of the spraying takes place, talking to those affected. He draws a vivid and damning picture of a futile and indiscriminate chemical war, waged largely on the poor.
Analytical Hierarchy Process Algorithm for Traffic Sign Improvement Priority

- Traffic signs are part of road equipment that is very important for motorists because they can provide direction while on the highway, and if there is damage, repair or replacement must be carried out immediately because it can cause traffic accidents. Data collection for damaged traffic signs is still done using the manual method, so it takes a long time. Therefore, a web-and android-based application was designed that implements the Analytical Hierarchy Process (AHP) algorithm in determining the priority of repair or replacement of traffic signs on the route of South Sulawesi Province. As a result of this research, the public can report the type of damage and its location via Android, and then the officer processes the data so that it displays the type of damage that is a priority for repair or replacement. Implement the Analytical Hierarchy Process algorithm into the application for prioritization of traffic sign improvement using two (two) web-based and Android platforms. System design using UML produces use cases (2 actors, admin, and user) and class diagrams (15 admin classes and 4 user classes). The black box used as a test produced 40 modules, of which all were in line with expectations.
Serum-Based Lipid Panels for Diagnosis of Idiopathic Parkinson’s Disease

Parkinson’s disease (PD) is a highly prevalent neurodegenerative movement disorder with an unclear etiology and a lack of definite diagnostic tests and effective treatments. About 95% of PD cases are idiopathic, in which none of the well-known genes underlying familial parkinsonism are mutated. We used untargeted liquid chromatography–mass spectrometry (LC-MS/MS) to profile the serum lipidome of 50 patients with different stages of idiopathic PD (early, mid, or advanced) and 45 age-matched controls. When comparing the PD patients to the control subjects, 169 lipids were significantly altered in both a univariate analysis and a multivariate partial least-squares discriminant analysis (PLS-DA). Compared to the controls, the patients with PD had higher levels of unsaturated triacylglycerides (e.g., TG O-56:9 and TG 52:3), saturated lysophosphatidylcholines (LPC 17:0, 16:0, and 15:0), and hydroxyeicosatetraenoic acid (12-HETE), while lower levels of phosphatidylserines (e.g., PS 40:4 and PS 16:0_22:4), sphingomyelins (SM 42:1), and ceramides (e.g., Cer 40:0 and 42:0) were found between the PD patients and the controls. A panel of 10 significantly altered lipids (PS 40:0, Cer 40:0, Cer 42:0, LPC 17:0, LPC 15:0, PC 37:7, PE O-40:8, PC O-42:4, FA 23:0, and SM 42:1) resulted in a strong receiver operating characteristic curve with an AUC = 0.974. This panel may, therefore, be useful for diagnosing PD. In addition, lipid panels may prove useful for distinguishing among the progression stages of PD. Using one-way ANOVA, 155 lipid species were significantly altered among the PD stages. Parkinson’s disease progressed from the early to advanced stages with decreasing levels of PC 31:1, PC 38:4, and LPE 22:5. Conversely, LPC-O 20:0, PC O-42:3, FA 19:0, and FA 22:2 showed an increase in their levels with disease progression. Overall, this study shows an intriguing number of robust changes in specific serum lipids that may become useful for diagnosing PD and its progression, once panels have been validated in larger clinical trials and prospective studies.
Correlation of Fast Rates of Snow Glide with Full-Depth Avalanche Occurrence

Free-water at the snow/ground interface is a very important controlling mechanism for snow glide. Free-water at the snow/ground interface affects the material properties of snow and promotes separation of the snow pack from the ground, allowing for higher rates of snow glide (McClung and Clarke, 1987). It is thought that intervals of rapid snow glide precede, or at least coincide with, the release of full-depth avalanches. Full. <fepth avalanches are difficult to predict using traditional avalanche forecasting methods and are also more difficult to control using explosives. Using measured rates of snow glide and meteorological variables, this research will help to characterize the relationship between fast rates of snow glide and the release of full-depth avalanches.
Spis ludności i prawda / Population Census and Truth

The article discusses the quality of population census data - information obtained in the oldest, largest and most famous statistical surveys. In particular, the quality assessment of census data refers to the Polish experience. The article aims to propose an integrated approach to censuses, based on administrative records and sample surveys. Despite a long tradition, as well as a well-developed research methodology, censuses do not provide ‘perfect’ results. First of all, the census as a comprehensive study may be burdened with non-random errors. Taking into account all the different methods for conducting censuses, including the traditional method, using data from administrative records with sample surveys and the mixed method, different sources of error are analyzed.
Résistance à la fissuration en fatigue à temperature élevée de l'alliage TA6V

Une etude de la fissuration en fatigue de l'alliage de titane ta6v sous forme structurale biphasee a ete entreprise avec trois nuances de microstructure dans differentes conditions d'environnement et de temperature. L'influence de la microstructure s'est averee limitee a l'ambiante en precisant toutefois qu'une nuance presentant une proportion de phase alpha importante constituee d'une part de grains equi-axes et de lamelles, d'autre part presente la meilleure resistance a la fissuration. Le mecanisme propose repose sur la presence de phase d'interface permettant la formation de fissures secondaires ce qui conduit a la reduction de l'intensite des concentrations de contrainte en pointe de fissure principale et en consequence a la diminution de la vitesse de propagation. L'influence de l'environnement a pu etre mise en evidence grace aux essais de reference en milieu inerte. On retiendra d'une maniere generale que les essais a l'air ambiant conduisent a une acceleration de la vitesse de propagation par rapport au vide qu'on peut attribuer a un processus de fragilisation du materiau induit par la vapeur d'eau ou l'oxygene. Les essais effectues a temperatures elevees a l'air ambiant et a r variable ont revele deux mecanismes de propagation distincts suivant le domaine de vitesse consideree: une propagation liee aux processus d'adsorption pour les vitesses moyennes semblant atteindre une saturation pour une temperature situee autour de 300c a une frequence d'essai de 0,5 hz et une propagation assistee par la fragilisation attribuee a l'oxygene dans le domaine des basses vitesses ou la saturation semble s'effectuer autour de 400c pour une frequence d'essai de 0,5 hz. La propagation sous vide et particulierement a 300c a revele dans le domaine des basses vitesses un regime de propagation lente appele pseudostade i ou un seul systeme de glissement semble active. Pour les vitesses superieures on retrouve comme a l'air ambiant un regime de propagation en stade ii impliquant la mise en uvre de plusieurs systemes de glissement
Essays on new models and the Mellin transform: experiments in survival and radar data

Dados de sobrevivencia foram aplicadas em varios contextos, tais como o tempo de sobrevivencia dos componentes mecânicos, os tempos de falha dos filmes isolantes eletricos e em dados censurados de ensaios clinicos de câncer de cabeca e pescoco. Os dados resultantes tem natureza positiva, frequentemente marcadas por censura e caudas pesadas. Este ultimo fato sugere o uso de modelos flexiveis; metodos de inferencia tal como estimacao e bondade de ajuste; e ajuste condicional (por exemplo, regressao e series temporais). Varios modelos tem sido propostos para descrever dados de sobrevivencia na forma de familias definidas pela transformacao de distribuicoes de referencia (chamadas de baselines). Uma delas e a familia beta-G proposta por Eugene et al. [Beta-normal distribution and its applications. Communication in Statistics-Theory and Methods, 31, 497-512]. Embora a classe beta-G seja capaz de produzir ate mesmo distribuicoes para dados bimodais, ela carece tanto de metodos mais eficientes de bondade de ajuste como de estimacao. A problematica que suscita a proposta de metodos de comparacao de ajustes e distinguir a diferenca entre dois modelos definidos na classe beta-G usando criterios: (i) sem uma regra envolvendo um ponto de corte associado ou (ii) proprios de modelos encaixados (a exemplo do criterio de Informacao de Akaike). Alem disso, a funcao de verossimilhanca para modelos beta-G em experimentos reais e sinteticos tem sugerido a proposta de criterios de estimacao que nao trabalhe diretamente com esta funcao. Nesta tese, imagens de radar de abertura sintetica (Synthetic Aperture Radar-SAR) sao consideradas como um contexto concreto para modelagem de dados. O SAR tem sido indicado como uma importante ferramenta para resolver problemas de sensoriamento remoto, isso se deve a sua capacidade de operar independente de condicoes atmosfericas e produzir imagens em alta resolucao espacial. Entretanto, as imagens SAR tem seus atributos corrompidos por um ruido multiplicativo que impoe o uso de um modelo adaptado a sua presenca. Uma importante caracteristica em imagens SAR e a imagem em intensidade SAR, que e definida como a norma de um retorno complexo. Alem disso, experimentos com dados reais de intensidades SAR produzem dados multimodais. Varios trabalhos destinados a modelar dados de intensidade SAR usam misturas de distribuicoes, mas essa estrategia pode impor um grande numero de parâmetros. Nesta tese, adotamos a transformada de Mellin como um caminho para obter novas ferramentas para a compreensao de dados de analise de sobrevivencia. Com isso nos propomos: (i) uma nova medida de bondade de ajuste no aspecto qualitativo e quantitativo para dados de analise de sobrevivencia e (ii) um metodo de estimacao independente da verossimilhanca. No contexto da analise de imagens SAR, apresentamos: (i) dois novos modelos de probabilidade: a composta Poisson truncado Cauchy e a familia G-G com tres e quatro parâmetros, respectivamente; e (ii) um modelo de regressao na distribuicao Gɪ⁰ para dados speckled.
Rheological properties of wheat dough with the addition of green buckwheat flour

Bread is the most affordable products in the world. In addition, bread and bakery products have high indicators of nutritional and biological value. The most important direction in this sphere, according to experts, is the enrichment of bakery products with proteins, essential amino acids, and various macro- and micronutrients. At the same time, it is important that the final product has high quality, attractive consumer properties and can be effectively sold in retail chains. Rheological studies make it possible to judge the characteristics, quality and prospects of obtaining bakery products. To the date, there is not enough information about the effect of green buckwheat flour additives on the rheological parameters of dough semi-finished products. The solution of this problem formed the basis of the study. According to the conducted research, it is optimal to introduce up to 10% of green buckwheat flour into the dough semi-finished product. In these dosages, green buckwheat flour does not have a negative effect on the rheological properties of the dough. Therefore, the resulting mixture can be used for standard bread production technologies. In addition, the addition of green buckwheat flour in the quantities described has a positive effect on the farinograph quality number, the stability of the dough and the degree of softening of the dough compared to the check sample.
Odd spin frustration in ultrathin Cr(001) films studied by spin-polarized scanning tunneling microscopy

3-nm-thick Cr(001) films have been fabricated successfully with atomically flat and clean terraces. Images of both the topological and magnetic structures of the Cr films were obtained at 300 K using spin-polarized scanning tunneling microscopy. The observed magnetic image of the Cr(001) surface indicated that the topological antiferromagnetic (AF) order appeared in a series of adjacent terraces with two types of spin frustration caused by screw dislocations leading to the modification of the topological AF order. One type of the spin frustration is accompanied with the narrow domain wall between two screw dislocations. The other type is due to complex spin frustration caused by a cluster of odd number of screw dislocations, which is explained through a micromagnetic simulation.
RESPIRATORY FUNCTION IN CHILDREN WITH CEREBRAL PALSY

Purpose: to characterize the pulmonary function of children with cerebral palsy (CP) and to compare it with children with typical development (TD). Methods: the study was with 20 children TD and 21 CP, both sexes aged between 6-12 years (9.41 ± 1.47), with cognitive ability to perform the spirometry test. Wilcoxon / Mann Whitney test hypothesis compare the values obtained in both groups and intragroup in relation to gender and in the functional classifications of CP. Results: TD group showed a significant difference and higher spirometry values in males, whereas for children with CP there was no difference in relation to sex. In addition, the TD group demonstrated better values of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and peak expiratory flow (PEF) than the CP group. There were significant differences and better spirometric values for children with CP less compromised in the comparisons between the functional, topographic levels, and functional gait pattern. Conclusion: there is a tendency towards obstructive and restrictive breathing patterns in the children with CP, observable mainly by the decrease in FVC, FEV1, and PEF compared DT. CP children with worse functionality have greater respiratory impairments.
Prediction of High Tunnel Magnetoresistance Ratios in (111)-Oriented Junctions with a SrTiO3 Barrier

We theoretically study the tunnel magnetoresistance (TMR) effect in novel (111)-oriented magnetic tunnel junctions (MTJs) with SrTiO3 barriers X/SrTiO3/X(111) (X = Co, Ni). Our ballistic transport calculation combining the density-functional theory and the Landauder formula obtains high TMR ratios of ~ 500% for the Co-based MTJ and ~300% for the Ni-based MTJ. By analyzing band structures in each region of the MTJs, we find that the high TMR ratios originate from the coherent tunneling of the half-metallic Λ1 state in Co (Ni), where the Λ1 state is the rotationally symmetric electronic state along the Λ line corresponding to the [111] direction. Since the in-plane lattice periodicity of SrTiO3 is twice as long as that of fcc Co (Ni), the original band structures of Co (Ni) are folded in the kx-ky plane, leading to the half-metallicity in the Λ1 state. The band-folding-driven high TMR ratios found in this study is a novel mechanism of high TMR ratios in (111)-oriented MTJs, in sharp contrast to the interfacial-resonance mechanism reported in our previous works.
