Published: April 2024

This article presents a study on the thermal sensitivity of anisotropic thin sheets, focusing specifically on their behavior during hot bulge tests. Anisotropic materials exhibit different mechanical properties in different directions, and understanding their response to thermal loading is crucial for various engineering applications.
The experimental investigation involves subjecting thin sheets of anisotropic materials to controlled thermal conditions and measuring their response. The hot bulge test, a well-established method, is employed to analyze the behavior of the sheets under elevated temperatures. This test involves applying a controlled internal pressure to a heated circular and elliptical specimen, causing it to deform and form a bulge.
Through this study, the thermal sensitivity of anisotropic thin sheets is characterized by analyzing the bulge height, bulge profile, and strain distribution. The influence of various factors, such as temperature, material anisotropy, and loading rate, is examined to understand their effects on the sheet's response.
Experimental results reveal significant variations in the thermal sensitivity of anisotropic thin sheets, depending on the material's orientation and temperature. The study demonstrates that certain orientations exhibit greater sensitivity to thermal loading, leading to distinct bulge profiles and strain distributions.
Furthermore, numerical simulations are conducted using finite element analysis to validate and complement the experimental findings. The simulation models incorporate the anisotropic material properties and the thermal boundary conditions, enabling a comprehensive understanding of the thermal sensitivity behavior observed experimentally.
The outcomes of this study provide valuable insights into the thermal behavior of anisotropic thin sheets, particularly in the context of hot bulge tests. The findings contribute to the knowledge base of material characterization and can aid in the design and optimization of structures and components subjected to thermal loading, where anisotropic materials are involved.
Hypercholesterolemia Increases the Risk of Colorectal Cancer by a Tet-1-Dependent HSC-Autonomous Mechanism
Authors: Messina Louis , Tie Guodong 
Published: April 2024

The annual, age-standardized colorectal cancer (CRC) incidence rate has decreased by 46% from its peak in 1985. However, this long-standing decline in cases of CRC slowed due mainly to an increase in incidence in individuals younger than 50 years of age. For those less than 50 years of age, CRC is the leading cause of cancer deaths in men and the second in women. At least half of all cases of young-onset CRC are linked to lifestyle risk factors, including obesity. Hypercholesterolemia, a common metabolic disorder in obese people, has been shown to increase the risk of colorectal cancer, but the mechanism is unknown. We will show that hypercholesterolemia increases the incidence and pathological severity of colorectal cancer by inducing an oxidant stress-dependent hematopoietic stem cell-autonomous mechanism. The oxidized-LDL increase in HSC oxidant stress initiates a signaling pathway that culminates in the increased expression of miR101c that downregulates Tet1. This downregulation of Tet1 reduces the expression of the genes critical to the production and cytotoxicity of natural killer T cells and T cells, thereby impairing cancer immunosurveillance against colorectal cancer. This reveals a novel mechanism where a metabolic disorder induces epigenetic reprogramming of natural killer T cells and γδT gene expression within hematopoietic stem cells.

Microplastics (MP) are plastic fragments smaller than 5 mm found in water columns and sediments, posing a threat to marine life due to their toxicological potential for the absorption and release of harmful compounds such as heavy metals. Mussels exhibit high filtration rates with the ability to bioaccumulate microplastics and are considered bioindicators of environmental contamination. The present study aims to evaluate the impact of microplastics in different geographical areas to identify their effects on ecosystems and potential damage to human health, focusing on the bioaccumulation capacity of MP in mussels. Samples of water, sediment, and mussels (Mytilus) from the Central Mexican Pacific were analyzed using optical microscopy and contamination indices. The levels of heavy metals detected at the sampling sites suggest low contamination, according to the Heavy Metal Evaluation Index (HEI). In Juluapan Lagoon, 93% of the MP particles found were fibers, with similar results in Barra de Navidad (75%). In Puerto Interior, Laguna Valle de Garzas, and Juluapan Lagoon, fibers accounted for 100% of the identified MP in water. The concentration of MP in water reached up to 7 MP/L, and 13 MP/mussel in Barra de Navidad. The presence of associated contaminants and MP suggests potential harmful effects on environmental health due to the high bioaccumulation of microplastics in mussels.

Judicial protection in case of banking transactions using a duplicate SIM card
Authors: Юсупов Д.Д. 
Published: April 2024

современный человек привык быть мобильным, быстрый обмен данными и бесконечный поток информации стали нормой повседневной жизни, вследствие чего многие услуги перешли в онлайн. Исключением не стал и банковский сектор. Так у каждого банка разработано свое банковское приложение, вмещающее в себя не только весь спектр банковских услуг, но и побочные продукты, такие как: бухгалтерские услуги, юридические консультации, брокерские услуги. Банковские приложения из года в год становятся только популярнее, и некоторые банки вовсе отказались от формата офиса в пользу онлайн формат. Вместе с тем, отсутствие человека при совершении сделки ставит вопрос о его идентификации, из-за чего, как правило, приложение привязывается к номеру телефона (сим-карте). Однако, такой вариант идентификации не исключает факт мошеннических действий, вследствие чего одним из популярных способов неправомерного завладения учетной записи приложения является доступ к приложению с помощью дубликата сим-карты.
modern people are used to being mobile, fast data exchange and an endless stream of information have become the norm of everyday life, as a result of which many services have moved online. The banking sector was no exception. So each bank has developed its own banking application, which includes not only the entire range of banking services, but also by-products such as accounting services, legal advice, brokerage services. Banking applications are only becoming more popular from year to year, and some banks have completely abandoned the office format in favor of the online format. At the same time, the absence of a person during the transaction raises the question of his identification, which is why, as a rule, the application is linked to a phone number (SIM card). However, this identification option does not exclude the fact of fraudulent actions, as a result of which one of the popular ways to illegally take over an application account is to access the application using a duplicate SIM card.
Guidelines to optimise the sensory detection of 2,4,6-trichloroanisole in neutral spirit and whisky
Authors: Baxter Irene , Réveillé Augustin , Conner John 
Published: April 2024

Why was the work done: Guidelines are required to optimise the sensory detection of musty/stale taints in alcoholic spirits caused by 2,4,6-trichloroanisole. Early detection of the taint is necessary as the low sensory threshold can result in significant quality issues and masking the musty/stale off-note through blending is difficult.
How was the work done: The standard industry practice for ‘nosing’ is to dilute samples of spirit to 20% ABV to prevent sensory fatigue. It is not known if 20% ABV is the optimal concentration for detecting 2,4,6-trichloroanisole. In this study, the effects of ethanol concentration on the detection of the taint were evaluated using a sensory panel and gas chromatography-mass spectroscopy. The efficacy of nosing versus tasting to detect 2,4,6-trichloroanisole was investigated at different dilutions of distilled spirits. Further, the stability of this off-note at 20% ABV was determined to assess if the taint could be detected by nosing over a working day. Finally, the serving temperature of the sample was assessed in the sensory perception of the taint.
What are the main findings: The recommendations to optimise the sensory detection of 2,4,6-trichloroanisole in spirit samples are (i) nose samples at 20% ABV, (ii) as soon as possible after dilution conduct sensory tests and (iii) chill the sample.
Why is the work important: The limits of detection for conventional solid phase microextraction with gas chromatography-mass spectroscopy are typically above the threshold of human perception. Therefore, the industry needs to maximise the detection by sensory panellists of contaminated whisky samples to ensure the product does not go to market so as to avoid any reputational damage.
Screening and Diagnosis of Rare Thalassemia Variants: Is Third-Generation Sequencing Enough?
Authors: Tang Haishen , Xiong Yi , Tang Jiaqi , Wang Xiaohong , Wang Ya , Huang Liping , Wang Runli , Wang Degang 
Published: April 2024

Context.—
Rare thalassemia subtypes are often undiagnosed because conventional testing methods can only identify 23 common types of α- and β-thalassemia.

Objective.—
To assess a comprehensive approach for the screening and diagnosis of rare thalassemia.

Design.—
The study cohort included 72 individuals with suspected rare thalassemia variants. Screening was conducted by next-generation sequencing (NGS) combined with third-generation sequencing (TGS) and chromosomal microarray analysis (CMA)/copy number variation sequencing.

Results.—
Of the 72 individuals with suspected rare thalassemia, 49 had rare α- or β-gene variants. NGS combined with gap polymerase chain reaction detected a total of 42 cases, resulting in a positive detection rate of 58.3%. Additionally, 4 α-globin genetic deletions were identified by TGS, which increased the variant detection rate by 5.6%. Two samples with a microdeletion of chromosome 16 or 11 were detected by CMA, which increased the detection rate by 2.8%. For one sample, reanalysis of the NGS and TGS data confirmed the presence of the β41-42/βN and βN/βN mosaic. The HBB:c.315 + 2delT mutation was initially reported in Guangdong Province, China. Two HBB gene mutations (HBB:c.315 + 5G&gt;C and HBB:c.295G&gt;A) and 4 rare HBA gene deletions (–11.1, -α27.6, -α2.4, and -α21.9) were initially identified in the Zhonshan region. The hematologic phenotypes of all rare cases in this study were clarified.

Conclusions.—
Rare thalassemia variants are more common than previously thought. Despite advancements in TGS, there is still no foolproof method for detection of all types of thalassemia. Thus, a comprehensive approach is necessary for accurate screening and diagnosis of rare thalassemia variants.
