For how to store and transport hydrogen, the first thought is to store hydrogen directly in the cylinder. However, this method is not desirable, because generally at least 700 atm high pressure, the hydrogen contained in the cylinder to be useful. Therefore it is very unsafe at such high pressures. In This paper, we design and production of a new generation of solid-state hydrogen storage and discharge container. The goal of 'development of solid-state hydrogen storage technology' is to break through the bottlenecks of hydrogen storage technology safety, hydrogen storage density, high-efficiency hydrogen absorption and release, transportation safety, and engineering practice. © 2024 IEEE.

In the field of applied computer vision, the three-dimensional (3d) object recognition is a very important technique which can be used to determine objects from a certain direction of the image for arbitrary 3d objects. These skills are useful in military applications, such as moving target recognition and coastal surveillance. Computer vision recognition allows fast response and all day long reconnaissance. The purpose of establishing a ship recognition system is to research and develop effective ship contour capture in the natural sea environment. We can develop a ship recognition system that is reliable and fast based on a database of ship images. We propose a recognition algorithm for ship images. This system utilizes gradient vector flow to capture the ship image contour first and calculates the geometric eigenvalue using this contour and Fourier descriptor. The eigenvalues are used to perform separate rough and detailed recognition. A graph.c user interface is developed and the validity of the proposed technique is demonstrated using identifying images. ©ICROS.

differentiation of induced pluripotent stem cells (iPSCs) is an extremely complex process that has proven difficult to study. In this research, we utilized nanotopograph. to elucidate details regarding iPSC differentiation by developing a nanodot platform consisting of nanodot arrays of increasing diameter. Subjecting iPSCs cultured on the nanodot platform to a cardiomyocyte (CM) differentiation protocol revealed several significant gene expression profiles that were associated with poor differentiation. The observed expression trends were used to select existing small-molecule drugs capable of modulating differentiation efficiency. BRd K98 was repurposed to inhibit CM differentiation, while iPSCs treated with NSC-663284, carmofur, and KPT-330 all exhibited significant increases in not only CM marker expression but also spontaneous beating, suggesting improved CM differentiation. In addition, quantitative polymerase chain reaction was performed to determine the gene regulation responsible for modulating differentiation efficiency. Multiple genes involved in extracellular matrix remodeling were correlated with a CM differentiation efficiency, while genes involved in the cell cycle exhibited contrasting expression trends that warrant further studies. The results suggest that expression profiles determined via short time-series expression miner analysis of nanodot-cultured iPSC differentiation can not only reveal drugs capable of enhancing differentiation efficiency but also highlight crucial sets of genes related to processes such as extracellular matrix remodeling and the cell cycle that can be targeted for further investigation. Our findings confirm that the nanodot platform can be used to reveal complex mechanisms behind iPSC differentiation and could be an indispensable tool for optimizing iPSC technology for clinical applications. © 2024 The Authors.

Purpose: We investigated the volumetric changes in the components of the cholinergic pathway for patients with early mild cognitive impairment (EMCI) and those with late mild cognitive impairment (LMCI). The effect of patients’ apolipoprotein 4 (APOE-ε4) allele status on the structural changes were analyzed. Methods: Structural magnetic resonance imaging data were collected. Patients’ demograph.c information, plasma data, and validated global cognitive composite scores were included. Relevant features were extracted for constructing machine learning models to differentiate between EMCI (n = 312) and LMCI (n = 541) and predict patients’ neurocognitive function. The data were analyzed primarily through one-way analysis of variance and two-way analysis of covariance. Results: Considerable differences were observed in cholinergic structural changes between patients with EMCI and LMCI. Cholinergic atroph. was more prominent in the LMCI cohort than in the EMCI cohort (P < 0.05 family-wise error corrected). APOE-ε4 differentially affected cholinergic atroph. in the LMCI and EMCI cohorts. For LMCI cohort, APOE-ε4 carriers exhibited increased brain atroph. (left amygdala: P = 0.001;right amygdala: P = 0.006, and right Ch123, P = 0.032). EMCI and LCMI patients showed distinctive associations of gray matter volumes in cholinergic regions with executive (R² = 0.063 and 0.030 for EMCI and LMCI, respectively) and language (R² = 0.095 and 0.042 for EMCI and LMCI, respectively) function. Conclusions: Our data confirmed significant cholinergic atroph. differences between early and late stages of mild cognitive impairment. The impact of the APOE-ε4 allele on cholinergic atroph. varied between the LMCI and EMCI groups. © 2024, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

This paper presents a comprehensive review on the current state of digital simulation technology and its strategic application usages with a key focus on advanced compression garments. Although three-dimensional (3d) digital garment simulators have significantly impacted the apparel and textile industry, their use has been limited to visual prototyping, quality checking, or marketing. The ph.sical properties of garment simulators have been overlooked in advanced functional manufacturing. This literature review investigates the possibility of strategically utilizing virtual ph.sical properties to enhance garment functions, specifically in wearables and medical-grade compression fields. The first ph.se of this paper gives an overview of the current state of 3d garment simulation tools and their measurement features. This is followed by a gap analysis between simulated and ph.sical property evaluations, focusing on minimizing the gaps. The literature is thoroughly examined to identify appropriate studies that uses digital tools for compressional garments and add value to wearables and healthcare applications. This paper provides valuable insights for apparel and textile engineers, enabling them to better understand the limitations and capabilities of garment simulators in improving advanced features for specific end users. © TBIS 2023.

Augmented reality (AR) is a technology that instantly merges digital pictures with the real scene. The perspective near-eye display is a key module of AR, through which computer-generated pictures or videos can be displayed in the existing environment. The purpose of this research is to establish the system structure of an augmented reality near-eye display device and to design the off-axis two-piece reflective asph.rical mirror. Because AR glasses are wearable and are worn close to the eyes, not only the optical performance of the display but also the clear vision of the user needs to be considered. In this study, an off-axis two-piece reflective asph.rical mirror is used as the optical system of the AR for displaying the digital image. The micro-display is placed at the focal point of the optical system to form a digital image, and the horizontal movement of the micro-display along the optical axis is controlled by a precise displacement mechanism so that the patient with uncorrected myopia or hyperopia can see the digital picture and real scene. Because the right and left micro-displays move horizontally independently, the user can see the images on the AR device, which becomes the biggest feature of this study. © 2023 IEEE.

Geotextile has been commonly used in civil and geotechnical engineering applications, and the majority of geotextiles is made of nonwoven fabrics. Therefore, this study combines crimped polyester (PET) fibers, recycled Kevlar unidirectional selvage fibers, and low-melting-point PET (LPET) fibers to form PET/Kevlar/LPET nonwoven geotextiles, and then examines how various neelde-punch depths influence mechanical properties of the resulting nonwoven geotextiles. The tensile strength, tearing strength, bursting strength, and static puncture resistance of the nonwoven fabrics increase as a result of an increase of 0.3 cm to 0.5 cm in needle-punch depth. However, an increase of 0.5 cm to 0.7 cm causes a slight decrease in all aforementioned properties. © (2014) Trans Tech Publications, Switzerland.

Geotextiles feature reinforcement, drainage, filtration, separation, and act as a moisture barrier, and are commonly used in civil and geotechnical engineering applications. Using nonwoven fabrics as geotextiles has become a recent trend;therefore, this study combines crimped polyester (PET) fibers, recycled Kevlar unidirectional selvage fibers, and low-melting-point PET (LPET) fiber to make PET/Kevlar/LPET nonwoven geotextiles, the mechanical properties of which are then examined. The test results show that the tensile strength and tearing strength of the PET/Kevlar/LPET nonwoven geotextiles increases as a result of an increasing needle-punch rate from 150 punches/min to 200 punches/min. The mechanical properties along the cross machine direciton (Cd) of the nonwoven geotextiles is greater than that along the machine direction (Md). When the needle-punching rate exceeds 200 punches/min, the mechanical properties of the nonwoven geotextiles slightly decrease.

Traumatic Brain Injury (TBI) is most commonly accident injury in modern society. The deterioration of cognition and memory is a common ph.nomenon caused by TBI. Most of the basic experiments used rats for pathological research. Moreover, an eight-arm maze was often used to test the spatial learning behavior of brain diseases, such as Alzheimer’s disease and TBI. However, most of maze experimental data were collected in manual records. This process would take a lot of manpower and time. Therefore, the research built an automatic tracking trajectory system of the eight-arm maze to collect experiment data. Furthermore, the path trajectory of the rat can be recorded in time. Finally, these path trajectory data were used to analysis behavior feature of TBI animals. The results showed that TBI rats have a 40%~80% chance of having a trajectory to the right.
