Spatially fractionated radiotherapy versus conventional radiotherapy in the treatment of soft tissue sarcoma: A multicenter, prospective, phase II, randomized controlled clinical trial protocol

Precision Radiation Oncology, EarlyView.
The first randomized controlled trial comparing spatially fractionated radiotherapy (SFRT) with conventional radiotherapy (CRT) for soft tissue sarcoma (STS) will evaluate efficacy and safety, offering critical evidence to optimize treatment strategies.

The invariants of the Clifford groups [PDF]

, 1999
The automorphism group of the Barnes-Wall lattice L_m in dimension 2^m (m not 3) is a subgroup of index 2 in a certain ``Clifford group'' C_m (an extraspecial group of order 2^(1+2m) extended by an orthogonal group).

Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

Small, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress

Density and duality theorems for regular Gabor frames

, 2015
We investigate Gabor frames on locally compact abelian groups with time-frequency shifts along non-separable, closed subgroups of the phase space. Density theorems in Gabor analysis state necessary conditions for a Gabor system to be a frame or a Riesz ...

Cusps of arithmetic orbifolds [PDF]

, 2006
This thesis investigates cusp cross-sections of arithmetic real, complex, and quaternionic hyperbolic $n$--orbifolds. We give a smooth classification of these submanifolds and analyze their induced geometry.

Automatic calculation of symmetry‐adapted tensors under spin‐group symmetry: STENSOR, a new tool of the Bilbao Crystallographic Server

Journal of Applied Crystallography, EarlyView.
STENSOR automatically computes symmetry‐adapted tensors under spin and magnetic point groups. It generates tensors for both spin and magnetic point groups from structural data files or spin‐group generators. The comparison permits separation of the effects due to spin–orbit coupling from non‐relativistic contributions, as illustrated by examples.We ...

Acral Melanocytic Lesions Under Conventional, Sub‐Ultraviolet Reflectance, and Ultraviolet‐Induced Fluorescence Dermoscopy: A Comparative Analysis

International Journal of Dermatology, EarlyView.
Conventional dermoscopy provided higher scores than ultraviolet‐induced fluorescence dermoscopy for parallel furrow pattern, parallel ridge pattern (PRP), fibrillar pattern, dots/clods, radial lines, blue–white structureless areas and blotch, and outperformed sub‐ultraviolet reflectance dermoscopy (sUVRD) for PRP and blue–white structureless areas ...

Traces of Hecke operators on Drinfeld modular forms for GL2(Fq[T])$\operatorname{GL}_2(\mathbb {F}_q[T])$

Mathematika, Volume 72, Issue 2, April 2026.
Abstract In this paper, we study traces of Hecke operators on Drinfeld modular forms of level 1 in the case A=Fq[T]$A = \mathbb {F}_q[T]$. We deduce closed‐form expressions for traces of Hecke operators corresponding to primes of degree at most 2 and provide algorithms for primes of higher degree.

Counting problems for orthogonal sets and sublattices in function fields

Mathematika, Volume 72, Issue 2, April 2026.
Abstract Let K=Fq((x−1))$\mathcal {K}=\mathbb {F}_q((x^{-1}))$. Analogous to orthogonality in the Euclidean space Rn$\mathbb {R}^n$, there exists a well‐studied notion of ultrametric orthogonality in Kn$\mathcal {K}^n$. In this paper, we extend the work of [4] on counting problems related to orthogonality in Kn$\mathcal {K}^n$.

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.
