Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Applied Categorical Structures, 2008 We revisit sheaves on locales by placing them in the context of the theory of quantale modules. The local homeomorphisms $p:X\to B$ are identified with the Hilbert $B$-modules that are equipped with a natural notion of basis. The homomorphisms of these modules are necessarily adjointable, and the resulting self-dual category yields a description of the

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Optimum Mode-Switching Assisted Adaptive Modulation
, 2001 Adaptive modulation techniques combat fading by employing a suitable modulation mode depending on the instantaneous channel conditions for improving the Bit Error Rate (BER) performance or the average through-put.

iScience, 2022 Summary: In nature, many organisms (e.g., chameleons) protect themselves by changing their colors in response to environmental changes. Inspired by these organisms, we present a multi-responsive, flexible, and structurally colored hydrogel film with a ...

Generalised pre-coding aided spatial modulation [PDF]
, 2013 A new Multiple Input Multiple Output (MIMO) transmission scheme termed as Generalised Pre-coding aided Spatial Modulation (GPSM) is proposed, where the key idea is that a particular subset of receive antennas is activated and the activation pattern ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Modules with Simple Multiplicity Modules
Journal of Algebra, 1995 Let \(G\) be a finite group, \(\mathcal O\) be a complete local commutative noetherian ring with an algebraically closed residue field \(k\) of nonzero characteristic \(p\). Let \(M\) be an indecomposable \({\mathcal O}G\)-module with vertex \(P\), \(\delta\) be a local point of \(P\) on \(\text{End}_{\mathcal O}(M)\) and \(V\) be the multiplicity \(k_*

Feasibility study for high bit rate pulse position modulation in fibre communications [PDF]
, 2013 With the rapid progress of optical communication systems, capacity limitation becomes important in high bit rate links. Overcoming this limitation may involve using different modulation and multiplexing methods, including RZ modulation with on-off keying
