The Dirichlet problem for a class of curvature equations in Minkowski space [PDF]

arXiv
In this paper, we study the Dirichlet problem for a class of prescribed curvature equations in Minkowski space. We prove the existence of smooth spacelike hypersurfaces with a class of prescribed curvature and general boundary data based on establishing the \emph{a priori} $C^2$ estimates.

Far Infrared Sensing Of The Oxidation State Of Heme Proteins [PDF]

arXiv, 2003
We propose a biosensor based on the change of terahertz (THz) dielectric response when a biotarget binds to a probe. The feasibility of this biosensor is examined by studying the change of THz transmission for thin films of heme proteins myoglobin (Mb) and cytochrome C (CytC) as a function oxygen binding.

Can optimal diversification beat the naive 1/N strategy in a highly correlated market? Empirical evidence from cryptocurrencies [PDF]

arXiv
This study systematically examines how several alternative approaches considered affect three aspects that determine portfolio performance (the gross return, the transaction costs and the portfolio risk). We find that it is difficult to exploit the possible predictability of asset returns. However, the predictability of asset return volatility produces

Controlled Ascent Rate Enhances Autophagy and Mitigates Acute Lung Injury in Rats Exposed to High‐Altitude Hypoxia by Inhibiting Oxidative Stress and Inflammation

Global Challenges, EarlyView.
This study explores how gradual ascent rates reduce acute pulmonary injury in rats exposed to high‐altitude hypoxia by activating autophagy and suppressing oxidative stress and inflammation. Results show that controlled ascent effectively mitigates such injury, highlighting its potential as a preventive strategy.

Physical properties and biological effects of ceramic materials emitting infrared radiation for pain, muscular activity, and musculoskeletal conditions

Photodermatology, Photoimmunology &Photomedicine, Volume 39, Issue 1, Page 3-15, January 2023., 2023
Abstract Background Up to 33% of the general population worldwide suffer musculoskeletal conditions, with low back pain being the single leading cause of disability globally. Multimodal therapeutic options are available to relieve the pain associated with muscular disorders, including physical, complementary, and pharmacological therapies.

Investigating the defoliating‐like (DL) VCG2A pathotype of Verticillium dahliae through identification and prediction of secreted proteins from genomes of Australian isolates

Plant Pathology, Volume 72, Issue 2, Page 334-341, February 2023., 2023
A defoliating‐like VCG2A Verticillium dahliae isolate was observed to have 20 secreted proteins in common with virulent phenotypes; interestingly half of these were most closely related to proteins from a VCG6 isolate. Abstract In Australia, recent investigations have reported the presence of a number of Verticillium dahliae pathotypes (VCG1A, VCG2A ...

Engineered Living Energy Materials

Interdisciplinary Materials, EarlyView.
Engineered living energy materials (ELEMs) are nascent research frontier for enabling sustainable energy conversion and storage. These materials exhibit unique characteristics such as self‐regeneration, biodegradability, environmental response, and evolutionary adaptability. This paper overviews different energy conversion bio‐modules, summarizes their

Impacts of Inorganic Arsenic Exposure on Genetic Stability of Human Mesenchymal Stromal Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Human mesenchymal stem/stromal cells (hMSCs) can differentiate into mesoderm‐type cells, making them suitable candidates for tissue repair therapies. However, their relatively low frequency in adult tissue necessitates ex vivo expansion prior to regenerative medicine applications, and therefore, long‐term hMSC genetic stability during ...

microRNA‐Mediated Regulation of Oxidative Stress in Cardiovascular Diseases

Journal of Clinical Laboratory Analysis, EarlyView.
ABSTRACT Background Cardiovascular diseases (CVDs) are the leading cause of mortality globally, often linked to oxidative stress. MicroRNAs (miRNAs) have emerged as significant regulators of oxidative stress within the cardiovascular system. Objective This review examines the complex relationship between miRNAs and oxidative stress, clarifying their ...

Catalase‐Encapsulated Nanoparticles via Surface Radical Polymerization for Periodontitis Therapy

Macromolecular Materials and Engineering, EarlyView.
This study introduces catalase‐encapsulated nanoparticles (CAT NPs) designed to target the Nrf‐2/HO‐1 pathway for the treatment of periodontitis. CAT NPs demonstrate potent antioxidative and anti‐inflammatory properties, significantly reducing reactive oxygen species (ROS) and cytokine levels.
