We investigate the critical behavior of systems exhibiting a continuous absorbing phase transition in the presence of a conserved field coupled to the order parameter. The results obtained point out the existence of a new universality class of nonequilibrium phase transitions that characterizes a vast set of systems including conserved threshold transfer processes and stochastic sandpile models.

Aging is a major risk factor for poor outcomes following respiratory infections. In animal models, the most severe outcomes of respiratory infections in older hosts have been associated with an increased burden of senescent cells that accumulate over time with age and create a hyperinflammatory response. Although studies using coronavirus animal models have demonstrated that removal of senescent cells with senolytics, a class of drugs that selectively kills senescent cells, resulted in reduced lung damage and increased survival, little is known about the role that senescent cells play in the outcome of influenza A viral (IAV) infections in aged mice.

The perception of objects is a challenging task that requires recognizing visual elements and integrating them into a whole. While human vision prioritizes attention to the overall configuration, data from other species suggests this bias towards global form perception is not universal. Studies with pigeons indicate preferential attention to local details when both local and global information may be diagnostic, but studies with other bird species are more limited.

HLA-E is a nonclassical, nonpolymorphic, class Ib HLA molecule. Its primary function is to present a conserved nonamer peptide, termed VL9, derived from the signal sequence of classical MHC molecules to the NKG2x-CD94 receptors on NK cells and a subset of T lymphocytes. These receptors regulate the function of NK cells, and the importance of this role, which is conserved across mammalian species, probably accounts for the lack of genetic polymorphism.

Article Synopsis
- Vinylene-linked Covalent Organic Frameworks (V-2D-COFs) are advanced materials known for their stable, crystalline structures and excellent optoelectronic properties, but their synthesis is limited due to challenges with C═C bonds.
- Postsynthetic modification (PSM) offers a solution by allowing the introduction of functional groups into these frameworks, thus expanding their potential applications.
- The study demonstrates a thiol-ene click reaction to successfully modify two COFs, enhancing their properties and structural versatility, which could lead to new applications in areas like hydrophilicity and proton conductivity.

Aging is a complex and universal process marked by gradual functional declines at the cellular and tissue levels, often leading to a range of aging-related diseases such as diabetes, cardiovascular diseases, and cancer. Delaying the aging process can help prevent, slow down, and alleviate the severity of these various conditions, enhancing overall health and well-being. Alpha-glucosidase inhibitors (AGIs) are a class of widely used antidiabetic drugs that inhibit alpha-glucosidase in the small intestinal mucosa, delaying carbohydrate absorption and reducing postprandial hyperglycemia.
