Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.

Prevalence of HCMV, HHV‐6, and HSV‐1/2 in the semen of men attending infertility clinics and their association with semen parameters

UroPrecision, EarlyView.
Abstract Background Viral infections have been identified as potential disruptors of male reproductive health. This study aimed to investigate the prevalence of human cytomegalovirus (HCMV), human herpesvirus 6 (HHV‐6), and herpes simplex virus types 1 and 2 (HSV‐1/2) DNA in semen samples from fertile and infertile men within the potential impact of ...

IgE Sensitization Patterns of Mothers and Their Offspring in the First Five Years of Life The CHILD Study

Allergy, EarlyView.
The spectrum of allergic sensitization in mothers and their offspring was characterized at ages 1–5 years at an extract‐ and molecular level in a North American birth cohort. Fel d 1 was the primary sensitizer in mothers, followed by Phl p 1. Perennial allergen sensitization (Der f 1, Der p 1) was rare at age one but rose sharply by age five.

2D Piecewise Linear Scalar Fields with Invertible Integral Lines

Computer Graphics Forum, EarlyView.
Abstract Integral lines of the gradient flow are standard features in continuously differentiable scalar fields that enjoy some useful properties: They cover the domain densely, do not split, merge, or intersect, and are therefore invertible. For widely used discretizations of scalar fields, the corresponding polygonal approximations of integral lines ...

Contouring Signed Distance Fields by Approximating Gradients

Computer Graphics Forum, EarlyView.
Abstract Signed distance fields are often represented by discrete samples (e.g., on a grid). Recovering the contour implicitly represented by the distance samples requires an approximation algorithm. Several recent approaches have shown that exploiting the information carried in each distance sample by explicitly constructing a surface point gives ...

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

On Simplices with a Given Barycenter That Are Enclosed by the Standard Simplex [PDF]

We present an optimization model defined on the manifold of the set of stochastic matrices. Geometrically, the model is akin to identifying a maximum-volume $n$-dimensional simplex that has a given barycenter and is enclosed by the $n$-dimensional ...
