Terahertz Modulation of Even-order Polarization in GaAs
IEEE Photonics JournalThe application of electric fields induces changes in the symmetry of crystals, which can be observed spectroscopically as variations in the even harmonic generation. In this study, we report the ultrafast modulation of GaAs crystal symmetry using strong

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Oscillation results for even-order quasilinear neutral functional differential equations
Electronic Journal of Differential Equations, 2011 In this article, we use the Riccati transformation technique and some inequalities, to establish oscillation theorems for all solutions to even-order quasilinear neutral differential equation $$ Big(ig[ig(x(t)+p(t)x(au(t))ig)^{(n-1)}ig]^gammaBig)' +

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

New Flag-Transitive Affine Planes of Even Order
Journal of Combinatorial Theory, Series A, 1996 Let \(V\) be a vector space of dimension \(2k\) over \(GF(q)\) with a nonsingular quadratic form \(Q\). An orthogonal spread is a family of \(q^{k - 1} + 1\) totally singular \(k\)-spaces such that each non-zero singular vector is in exactly one member of the family. The bilinear form \(Q(u + v) - Q(u) - Q(v)\) defines a symplectic structure. For \(q^m

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Oscillation properties of even-order linear differential equations [PDF]
Transactions of the American Mathematical Society, 1965 is considered for r(x) and p(x) continuous and r(x) > 0, p(x) # 0 on [a, a)). For n = 1, this equation has been the subject of many investigations over a number of years. For n = 2, J. H. Barrett [1]-[3] and W. Leighton and Z. Nehari [7] have recently considered equations of this type. For arbitrary n, similar equations have been investigated by W.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Oscillation Criteria for Certain Even Order Neutral Delay Differential Equations
International Journal of Differential Equations, 2014 We establish sufficient conditions for the oscillation of solutions of even order neutral type differential equations of the form [r(t)[x(t)+p(t)x(τ(t))](n−1)]′+q(t)f(x(σ(t)))=0.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
