Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Neutrosophic Refined Similarity Measure Based on Cosine Function [PDF]
Neutrosophic Sets and Systems, 2014 In this paper, the cosine similarity measure of neutrosophic refined (multi-) sets is proposed and its properties are studied. The concept of this cosine similarity measure of neutrosophic refined sets is the extension of improved cosine similarity ...

We find the area between $\cos^p x$ and $\cos^p nx$ as $n$ heads to infinity, and we establish a connection between these limiting values and the exponential generating function for $\arcsin x/(1-x)$ at sequence number A296726 on the OEIS.

Almost-distribution cosine functions and integrated cosine functions [PDF]
Studia Mathematica, 2005 Operator valued cosine functions were introduced in the 1950s to solve well-posed abstract second order Cauchy problems. Later, in analogy to operator semigroup theory, the strong continuity conditions were weakened to be able to treat also ill-posed problems.

Advanced Functional Materials, EarlyView.[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

On Multivalued Cosine Families [PDF]
Journal of Applied Analysis, 2007 The author gives the following result: Let \(X\) be a real Banach space and let \(K\) be a closed convex cone in \(X\) such that \(\text{int\,}K\neq\emptyset\). Assume that \(\{F_t: t\in\mathbb{R}\}\) is a regular cosine family of continuous linear multifunctions \(F_t: K\to cc(X)\) and \(x\in F_t(x)\) for all \(x\in K\) and \(t\in\mathbb{R}\).

Clean‐Limit 2D Superconductivity in a Thick Exfoliated Kagome Film
Advanced Functional Materials, EarlyView.This study reports clean‐limit 2D superconductivity in a thick kagome system, analogous to the 3D case. It observes a drop in superfluid stiffness near the superconducting transition and a cusp‐like feature in the angular dependence of the upper critical field.

Multiplicative Perturbations of Convoluted C-Cosine Functions and Convoluted C-Semigroups
Journal of Function Spaces and Applications, 2013 We obtain the multiplicative perturbation theorems for convoluted C-cosine functions (resp., convoluted C-semigroups) and n-times integrated C-cosine functions (resp., n-times integrated C-semigroups) for n∈ℕ.

Advanced Functional Materials, EarlyView.Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.
