Post-noon two-minute period pulsating aurora and their relationship to the dayside convection pattern [PDF]

open access: yesAnnales Geophysicae, 1999
Poleward-moving auroral forms, as observed by meridian-scanning photometers, in the vicinity of the cusp region are generally assumed to be the optical signature of flux transfer events.

On certain constructions of p-adic families of Siegel modular forms of even genus [PDF]

open access: yes, 2010
Suppose that p > 5 is a rational prime. Starting from a well-known p-adic analytic family of ordinary elliptic cusp forms of level p due to Hida, we construct a certain p-adic analytic family of holomorphic Siegel cusp forms of arbitrary even genus and ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

On Level p Siegel Cusp Forms of Degree Two

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012

Deformation of $\Gamma_0(5)$-cusp forms [PDF]

open access: yesMathematics of Computation, 2007
The author gives an algorithm for the numerical computation of the Eisenstein series on a Riemann surface of constant negative curvature. In this paper, she focuses on the computation of the poles of the Eisenstein series. For her algorithm, she explains the technicalities of deforming the group, deformation theory for cusp forms and Eisenstein series.

Form of cosmic string cusps [PDF]

open access: yesPhysical Review D, 1999
We classify the possible shapes of cosmic string cusps and how they transform under Lorentz boosts. A generic cusp can be brought into a form in which the motion of the cusp tip lies in the plane of the cusp. The cusp whose motion is perpendicular to this plane, considered by some authors, is a special case and not the generic situation.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Mathieu moonshine and Siegel Modular Forms

open access: yesJournal of High Energy Physics, 2021
A second-quantized version of Mathieu moonshine leads to product formulae for functions that are potentially genus-two Siegel Modular Forms analogous to the Igusa Cusp Form. The modularity of these functions do not follow in an obvious manner.

An explicit trace formula of Jacquet-Zagier type for Hilbert modular forms

open access: yes, 2018
We give an exact formula of the average of adjoint $L$-functions of holomorphic Hilbert cusp forms with a fixed weight and a square-free level, which is a generalization of Zagier's formula known for the case of elliptic cusp forms on ${\rm SL}_2(\mathbb{

Cusp forms and Hecke groups.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1988
Let \(\Gamma_ q\) be the so-called Hecke subgroup of \(SL_ 2({\mathbb{R}})\) generated by \(\begin{pmatrix} 0&-1 \\ 1&0 \end{pmatrix}\) and \(\begin{pmatrix} 1&2 \cos(\pi/q) \\ 0&1 \end{pmatrix}\) where \(q\geq 3\) is an integer. The author reports on his calculations of the point spectrum of the Laplace-Beltrami operator \(\Delta\) acting on suitable \
