An Abstract Result on Projective Aggregation Functions
Axioms, 2018 A general characterization result of projective aggregation functions is shown, the proof of which makes use of the celebrated Arrow’s theorem, thus providing a link between aggregation functions theory and social choice theory.

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

On Real Projective Spaces as Finsler Manifolds [PDF]
Proceedings of the American Mathematical Society, 1967 Let M be a finite-dimensional C3 manifold supplied with a C2 Finsler metric ds = F(x, dx), which is not necessarily even in dx. Let p designate the induced oriented topological metric. For any p E M, the antipodal locus of p is the set A(p)= {qEMIp(p, q)_p(p, r) for all rEM}.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

CR-hypersurfaces of complex projective space
International Journal of Mathematics and Mathematical Sciences, 1994 We consider compact n-dimensional minimal foliate CR-real submanifolds of a complex projective space. We show that these submanifolds are great circles on a 2-dimensional sphere provided that the square of the length of the second fundamental form is ...

One-dimensional super Calabi-Yau manifolds and their mirrors
Journal of High Energy Physics, 2017 We apply a definition of generalised super Calabi-Yau variety (SCY) to supermanifolds of complex dimension one. One of our results is that there are two SCY’s having reduced manifold equal to ℙ 1 $$ {\mathrm{\mathbb{P}}}^1 $$ , namely the projective ...

SPACES OF FREE LOOPS ON REAL PROJECTIVE SPACES
Kyushu Journal of Mathematics, 2005 Let \(L(X)\) be the free loop space on \(X\). For \(X= S^m\) or \(\mathbb{R} P^m\) there is a natural decomposition \(L_0(X)\coprod L_1(X)\) and natural maps \(Q^{n,d}_0(X)\to L_0(X)\), \(Q^{n,d}_1(X)\to L_1(X)\) where \(Q^{n,d}_{\varepsilon}(X)\), \(\varepsilon= 0,\,1\) are defined in terms of \(n\)-tuples of polynomials with real or complex ...

Kahler metric on the space of convex real projective structures on surface
, 2016 We prove that the space of convex real projective structures on a surface of genus $g\ge 2$ admits a mapping class group invariant K\"ahler metric where Teichm\"uller space with Weil-Petersson metric is a totally geodesic complex submanifold.Comment ...

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 ...
