Windings of Prime Geodesics [PDF]
International Mathematics Research NoticesAbstract The winding of a closed oriented geodesic around the cusp of the modular orbifold is computed by the Rademacher symbol, a classical function from the theory of modular forms. In this article, we introduce a new construction of winding numbers to record the winding of closed oriented geodesics about a prescribed cusp of a general

Visual and auditory attention in individuals with DYRK1A and SCN2A disruptive variants
Autism Research, EarlyView.Abstract This preliminary study sought to assess biomarkers of attention using electroencephalography (EEG) and eye tracking in two ultra‐rare monogenic populations associated with autism spectrum disorder (ASD). Relative to idiopathic ASD (n = 12) and neurotypical comparison (n = 49) groups, divergent attention profiles were observed for the monogenic

Geodesics and geodesic deviation for impulsive gravitational waves [PDF]
Journal of Mathematical Physics, 1998 The geometry of impulsive pp-waves is explored via the analysis of the geodesic and geodesic deviation equation using the distributional form of the metric. The geodesic equation involves formally ill-defined products of distributions due to the nonlinearity of the equations and the presence of the Dirac δ-distribution in the space–time metric.

Civil Engineering Design, EarlyView.Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Photogrammetric documentation in tunneling
Civil Engineering Design, EarlyView.Abstract Photogrammetric surveys for geological excavation documentation are standard practice in tunnel construction, benefiting from the sector's ongoing digitalization. However, the application of photogrammetry often remains confined to geological assessments. By creating comprehensive 3D models of excavated tunnels, it is also possible to evaluate

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet
Communications on Pure and Applied Mathematics, EarlyView.Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

Clinical presentation and neural correlates of stroke‐associated spatial delusions
European Journal of Neurology, Volume 30, Issue 1, Page 125-133, January 2023., 2023 Patients with spatial delusions after a right hemisphere stroke present a firm belief of place reduplication, transformation, or mislocation. Here, we characterize the clinical presentation of this syndrome and investigate its neural correlates. Abstract Background and purpose Incongruent beliefs about self‐localization in space markedly disturb ...

Unified f(R) gravity at local scales
European Physical Journal C: Particles and Fields, 2022 We explore the shifted $$f(R) (\propto R^{1+\delta })$$ f ( R ) ( ∝ R 1 + δ ) model with $${\delta }$$ δ as a distinguishing physical parameter for the study of constraints at local scales.

Geodesic walks in polytopes [PDF]
Proceedings of the 49th Annual ACM SIGACT Symposium on Theory of Computing, 2017 We introduce the geodesic walk for sampling Riemannian manifolds and apply it to the problem of generating uniform random points from polytopes in R^n specified by m inequalities. The walk is a discrete-time simulation of a stochastic differential equation (SDE) on the Riemannian manifold equipped with the metric induced by the Hessian of a convex ...
