Sufficient Reason Vindicated

open access: yesAnalytic Philosophy, EarlyView.
ABSTRACT I give an argument for a version of the principle of sufficient reason from several plausible principles about negative facts and sufficient conditions. I then give an argument for a slightly weaker version of the principle without the reference to negative facts.

The distribution of spacings between quadratic residues

open access: yes, 1998
We study the distribution of spacings between squares modulo q, where q is square-free and highly composite, in the limit as the number of prime factors of q goes to infinity.

Ultrafast Blood T1 Measurement Using Golden Angle Rotated Spiral k‐t Sparse Parallel Imaging (GASSP): Evaluations in Both Pre‐ and Post‐Contrast Conditions

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3351-3359, June 2026.
ABSTRACT Purpose Blood T1 is a key parameter for hemodynamic quantification in both non‐contrast‐ and contrast‐enhanced imaging. Individual vessel T1 has been measured using a modified Look–Locker scheme with multi‐shot EPI or FLASH in high spatial resolution, requiring ∼1 min.

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1151-1298, May 2026.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Estabilización activa de la polarización en enlace de fibra óptica monomodo para comunicaciones cuánticas

open access: yesAnales (Asociación Física Argentina), 2016
es contar con un enlace que preserve los estados de polarización para su uso en unsistema de distribución cuántica de claves. El esquema es capaz de generar los cuatro estados de polarizaciónlineales generadores de dos bases conjugadas: una corresponde ...

$\alpha$-additive functions and uniform distribution modulo one

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1984
Every nonnegative integer n can be written in the form \(n=\sum^{\infty}_{k=0}\epsilon_ k(n)z_ k\), where \(z_ k\) is the sequence of denominators of the convergents of the continued fraction expansion of a given irrational \(\alpha =[a_ 0;a_ 1,a_ 2,...]\), \(\epsilon_ 0(n)\in \{0,1,...,a_ 1-1\}\), \(\epsilon_ k(n)\in \{0,1,...,a_{k+1}\}\) (k\(\geq 1)\)

Non‐Migrating Thermal Tides in the Martian Lower Atmosphere Observed by EMM/EMIRS

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Thermal tides significantly influence Martian atmospheric dynamics and radiative transfer. However, the excitation mechanisms of non‐migrating tides, exhibiting diverse spatial structures, remain poorly understood due to the limited number of observations.

Glass bead games: enumeration of possible polytypes based on two stacking vectors and applications to the iron‐ore sinter phases SFCA and SFCA‐I

open access: yesActa Crystallographica Section A, Volume 82, Issue 3, Page 145-162, May 2026.
General formulas are presented that allow for the enumeration of polytypes based on translationally equivalent layers and two equivalent arrangements of adjacent layers involving distinct possible stacking vectors, t1 and t2. The results have been applied to the polytypism among two different polysomes of the family of so‐called silico‐ferrites of ...
