Spin Information from Vector-Meson Decay in Photoproduction [PDF]
Phys.Rev.C58:1086-1097,1998, 1998 For the photoproduction of vector mesons, all single and double spin observables involving vector meson two-body decays are defined consistently in the $\gamma N$ center of mass. These definitions yield a procedure for extracting physically meaningful single and double spin observables that are subject to known rules concerning their angle and energy ...

Pushforward and smooth vector pseudo-bundles [PDF]
arXiv, 2021 In this paper, we study a new operation named pushforward on diffeological vector pseudo-bundles, which is left adjoint to the pullback. We show how to pushforward projective diffeological vector pseudo-bundles to get projective diffeological vector spaces, producing many concrete new examples, together with application to smooth splittings of some ...

Revisiting the Vector and Axial-vector Vacuum Susceptibilities [PDF]
Phys.Lett.B669:327-330,2008, 2008 We re-investigate the vector and axial-vector vacuum susceptibilities by taking advantage of the vector and axial-vector Ward-Takahashi identities. We show analytically that, in the chiral limit, the vector vacuum susceptibility is zero and the axial-vector vacuum susceptibility equals three fourths of the square of the pion decay constant.

Covariance in Non-Commutative Algebra [PDF]
arXiv, 2023 Consider vector space over non-commutative division algebra. Set of automorphisms of this vector space is group $GL$. Group $GL$ acts on the set of bases of vector space (basis manifold) single transitive and generates active representation. Twin representation on basis manifold is called passive representation. There is no automorphism associated with

Evidence of novelty and specialization behavior in participatory science reporting
Oikos, Volume 2025, Issue 6, June 2025.Participatory science (or ‘citizen science') records are becoming increasingly useful for wildlife monitoring due to their volume and spatiotemporal coverage. Statistical analysis of these data can be challenging due to the many sources of sampling heterogeneity that need to be accounted for.

Polarization of B -> VV: experimental status [PDF]
arXiv, 2010 The experimental status of the polarization measurements in B to charmless vector-vector decays by both the Belle and Babar experiments is reviewed. The results obtained in related vector-tensor, axial vector-vector, and axial vector-axial vector modes are also given.

Alzheimer's &Dementia, Volume 21, Issue 5, May 2025.Abstract INTRODUCTION Deficiency in the aquaporin‐4 (AQP4) water channel has been linked to impaired amyloid beta (Aβ) clearance. However, a detailed morphopathological analysis of amyloid deposition following AQP4 therapeutic modulation remains unexplored.

arXiv, 2011 A permanental vector is a generalization of a vector with components that are squares of the components of a Gaussian vector, in the sense that the matrix that appears in the Laplace transform of the vector of Gaussian squares is not required to be either symmetric or positive definite.

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 5, Page 864-880, May 2025.ABSTRACT Quantitative understanding of drug penetration and exposure in the human central nervous system (CNS) and brain tumors is essential for the rational development of new drugs and optimal use of existing drugs for brain cancer. To address this need, we developed and validated a novel 9‐compartment permeability‐limited CNS (9‐CNS) physiologically

Sainsc: A Computational Tool for Segmentation‐Free Analysis of In Situ Capture Data
Small Methods, Volume 9, Issue 5, May 17, 2025.Spatially resolved transcriptomics methods can now profile the entire transcriptome, at full organism scale with nanometre resolution. Analysis frameworks that can efficiently and intuitively process the massive data generated by these methods are lacking.
