Characteristics of Rural Veterans Using VA Video‐to‐Home Telehealth or Community Care Network for Mental Healthcare

Psychiatric Research and Clinical Practice, EarlyView.
Objective To compare characteristics of rural veterans using VA brick and mortar (B&M), VA video‐to‐home telehealth (VA VTH), or VA community care network (CCN) for mental healthcare. Methods Rural VA patients that received at least 2 days of mental healthcare in fiscal year 2023 were classified as B&M, VA VTH, or CCN patients based on where they ...

Analytical Dual Flip Angle R1 Calculation Outside the Small‐Angle Regime

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2420-2428, April 2026.
ABSTRACT Purpose To evaluate a new analytical estimator for R1 and apparent proton density (A$$ A $$) from short‐TR dual flip angle data which does not rely on the small flip angle approximation and can thus be applied to a broader range of data, especially where relatively large flip angles are needed to achieve sufficient T1‐weighting for R1 ...

Quantitative Susceptibility Mapping in Skull Base Chordoma: In Silico Analysis and In Vivo Application Towards Indirect Hypoxia Assessment

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2092-2105, April 2026.
ABSTRACT Purpose To evaluate quantitative susceptibility mapping (QSM) beyond the brain through realistic simulations and to explore preliminary evidence that may be indicative of hypoxia in skull base chordomas (SBC). Methods Each step of the QSM pipeline was optimized within an in silico framework consisting of (i) phase unwrapping, (ii) background ...

On Diophantine equations involving Lucas sequences

Open Mathematics, 2019
In this paper, we shall study the Diophantine equation un = R(m)P(m)Q(m), where un is a Lucas sequence and R, P and Q are polynomials (under weak assumptions).

A generalization of Lucas polynomial sequence

Discrete Applied Mathematics, 2009
The authors consider the problem of a generalization of Lucas polynomial sequence. They obtain a generalized Lucas polynomial sequence from the lattice paths for the Delannoy numbers by allowing weights on the steps \((1,0),(0,1)\) and \((1,1)\).

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.

Water use and productivity of industrial hemp in the US central Great Plains

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Industrial hemp (Cannabis sativa L.) has been suggested as a broadleaf alternative for diversifying water‐limited cropping systems of the central Great Plains. With little recent production history in the region, our objective was to quantify water use of industrial hemp and its relationship with biomass yield to assess the potential for hemp ...

Generalized Commutative Mersenne and Mersenne–Lucas Quaternion Polynomials

Annales Mathematicae Silesianae
Generalized commutative quaternions generalize elliptic, parabolic and hyperbolic quaternions, bicomplex numbers, complex hyperbolic numbers and hyperbolic complex numbers. In this paper, we use the Mersenne numbers and polynomials in the theory of these
