ALMOST HOLOMORPHIC CURVES IN REAL ANALYTIC HYPERSURFACES

, 2023
Using the theory of exterior differential systems, we study the existence of germ of pseudo-holomorphic disk in a real analytic hypersurface locally defined in a complex manifold equipped with J a real analytic almost complex structure. The integrable case in C n with J the multiplication by i has been intensively studied by several authors [DF], [DA1]

Investigation of Aggregation Induced Emission Mechanism of Tetrabenzoheptafulvalene Derivative by Spin‐Flip Time‐Dependent Density Functional Theory (SF‐TDDFT)

Chemistry – An Asian Journal, EarlyView.
The SF‐TDDFT study of 10,10′,11,11′‐tetrahydro‐5,5′‐bidibenzo[a,d][7]annulenylidene (a tetrabenzoheptafulvalene derivative, abbreviated as THBDBA) in THF solution reveals the cause of its AIE behavior, While in solution intramolecular vibration leads to conical intersection between S0 and S1 states (i.

Kauzmann Paradox, Supercooling, and Finding Order in Chaos

Angewandte Chemie, Volume 137, Issue 10, March 3, 2025.
80 years later: Kauzmann temperature (Tk), and associated entropy catastrophe/paradox remains an enigma for nearly 80 years without any unifying resolution. Potential resolutions to the Kauzmann paradox, however, have so far been limited in the existence of an equilibrium ideal glass transition and traditional description of phase transition. Continued

Self‐Sensitized Fulgimides with Selective Multiplicity‐Based Three‐State Photoswitching

Chemistry – A European Journal, Accepted Article.
Precise control over excited‐state multiplicity is a powerful strategy for controlling photochemical reactivity, particularly in multimodal systems where different multiplicities lead to distinct reaction products. Here, we present a multiplicity‐sensitive, multimodal, fulgimide‐based system capable of three‐state photoswitching both in solution and in

Hodge loci associated with linear subspaces intersecting in codimension one

Mathematische Nachrichten, EarlyView.
Abstract Let X⊂P2k+1$X\subset \mathbf {P}^{2k+1}$ be a smooth hypersurface containing two k$k$‐dimensional linear spaces Π1,Π2$\Pi _1,\Pi _2$, such that dimΠ1∩Π2=k−1$\dim \Pi _1\cap \Pi _2=k-1$. In this paper, we study the question whether the Hodge loci NL([Π1]+λ[Π2])$\operatorname{NL}([\Pi _1]+\lambda [\Pi _2])$ and NL([Π1],[Π2])$\operatorname{NL ...

On a conjecture on aCM and Ulrich sheaves on degeneracy loci

Mathematische Nachrichten, EarlyView.
Abstract In this paper, we address a conjecture by Kleppe and Miró‐Roig stating that suitable twists by line bundles (on the smooth locus) of the exterior powers of the normal sheaf of a standard determinantal locus are arithmetically Cohen–Macaulay, and even Ulrich when the locus is linear determinantal.

Elucidating the Three‐Dimensional Structure of Piracetam through Rotational Spectroscopy

ChemistryOpen, EarlyView.
Neutral molecules of the nootropic drug piracetam are generated by laser ablation and structurally characterized by microwave spectroscopy. Two conformers differing in the exo/endo configuration of the pyrrolidine ring are detected, with exo being the predominant form.

Asymptotic behavior of Moncrief Lines in constant curvature space‐times

Bulletin of the London Mathematical Society, EarlyView.
Abstract We study the asymptotic behavior of Moncrief lines on 2+1$2+1$ maximal globally hyperbolic spatially compact space‐time M$M$ of nonnegative constant curvature. We show that when the unique geodesic lamination associated with M$M$ is either maximal uniquely ergodic or simplicial, the Moncrief line converges, as time goes to zero, to a unique ...

On the isoperimetric Riemannian Penrose inequality

Communications on Pure and Applied Mathematics, Volume 78, Issue 5, Page 1042-1085, May 2025.
Abstract We prove that the Riemannian Penrose inequality holds for asymptotically flat 3‐manifolds with nonnegative scalar curvature and connected horizon boundary, provided the optimal decay assumptions are met, which result in the ADM$\operatorname{ADM}$ mass being a well‐defined geometric invariant.

Multiscale Differential Geometry Learning for Protein Flexibility Analysis

Journal of Computational Chemistry, Volume 46, Issue 7, March 15, 2025.
Protein structure fluctuations, as measured by B‐factors, are closely linked to protein flexibility and function. Predicting B‐factors is an important research topic that has led to the development of various predictive models. Atomic interactions within proteins can be described using a family of low‐dimensional manifolds.
