Advanced Science, EarlyView.This study establishes a CT‐based radiomics framework to quantify intratumoral heterogeneity (ITH) in HNSCC. Using unsupervised clustering, tumor ROIs and VOIs are analyzed to calculate 2D/3D ITH scores. The score shows strong predictive value for prognosis and immunotherapy response, and is associated with tumor metabolism and immune microenvironment,

Design of Wheel-axle Transmission Scheme for High-speed Variable-gauge EMU Bogies
机车电传动, 2020 In view of the problem of torque transmission between wheels and axles of high-speed variable-gauge EMU bogies, three transmission schemes were put forward, which were roller spline transmission scheme, spline shaft transmission scheme and sleeve spline ...

An arbitrary mesh network scheme using rational splines [PDF]
, 1991 A C1 surface scheme is described which interpolates points defined on an arbitrary mesh network. The scheme involves the blending of strip ‘functions’ developed from a rational spline method.

Advanced Electronic Materials, EarlyView.Perpendicular electric and magnetic fields are used to control charge‐density‐wave (CDW) domain dynamics in quasi‐two‐dimensional h‐BN/1T‐TaS2 field‐effect devices. Electrical gating produces a non‐monotonic modulation of the CDW depinning threshold — behavior distinct from quasi‐one‐dimensional CDW systems.

The weighted v-spline as a double knot B-spline [PDF]
, 1991 The local support basis representation of the ‘weighted v-spline’ is derived in terms of double knot cubic B-splines, so providing a convenient form for computing and analysing the ...

Graphical Models, 2005 Summary: Constructing splines whose parametric domain is an arbitrary manifold and effectively computing such splines in real-world applications are of fundamental importance in solid and shape modeling, geometric design, graphics, etc. This paper presents a general theoretical and computational framework, in which spline surfaces defined over planar ...

Advanced Energy Materials, EarlyView.Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

Ban Glyphosate—Does It Affect the Swedish Farmers' Willingness to Grow Cover Crops?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The cultivation of cover crops is one of the new Eco‐scheme practices introduced in Sweden. This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban.
