Relationship Between Gut Microbiota and Cancer Neuro‐Immunity

Microbial Biotechnology, Volume 19, Issue 3, March 2026.
Tumour cells influence neural activity and microbiota homeostasis through cytokines and immune modulation. Meanwhile, gut microbiota regulates neural function through metabolic products, affects immune responses via neurotransmitters, feedback regulates neural activity and influences tumour microenvironment.

Neurocognitive Dynamics of Translating Information From a Spatial Map Into Action

Psychophysiology, Volume 63, Issue 3, March 2026.
ABSTRACT How do we translate information from a spatial map to action in our immediate surroundings? Despite the widespread use of various tools for orientation, from paper maps to GPS, this fundamental question remains unanswered in our understanding of human spatial navigation.

Kloosterman sums for Chevalley groups [PDF]

Transactions of the American Mathematical Society, 1993
A generalization of Kloosterman sums to a simply connected Chevalley group G G is discussed. These sums are parameterized by pairs ( w , t ) (w,t) where w w is an element of the Weyl group of G G and t t is an element of a

Stroke and motor outcomes are associated with regional and age‐specific changes in periodic and aperiodic cortical activity

Experimental Physiology, Volume 111, Issue 3, Page 1210-1227, 1 March 2026.
Abstract Historically, stroke and ageing have been associated with changes in narrow‐band periodic neuronal activity, but recent work has highlighted the importance of broad‐band aperiodic activity. Aperiodic activity is represented by the 1/f slope of power spectral density generated by cortical activity.

On Sums of SL(3,Z) Kloosterman Sums

, 2012
We show that sums of the SL(3,Z) long element Kloosterman sum against a smooth weight function have cancellation due to the variation in argument of the Kloosterman sums, when each modulus is at least the square root of the other.

An asymptotic local–global theorem on heights of some Kleinian group orbits

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We prove an asymptotic local–global theorem on the heights of point orbits of thin subgroups of Bianchi groups in H3$\mathbb {H}^3$.

Airy Sums, Kloosterman Sums, and Salié Sums

Journal of Number Theory, 1997
In 1993 \textit{W. Duke} and \textit{H. Iwaniec} proved that a certain class of cubic exponential sums can be expressed through Kloosterman sums twisted by a cubic character [Contemp. Math. 143, 255-258 (1993; Zbl 0792.11029)]. Their proof made use of one of the Davenport-Hasse theorems.

The Relationship Between Pre‐ and Post‐Migration Self‐Employment: Evidence From Italy and Spain

International Migration, Volume 64, Issue 1, January 2026.
ABSTRACT The home‐country self‐employment hypothesis, widely accepted in migration research, posits that immigrants from countries with high self‐employment rates are more likely to become self‐employed. However, supporting evidence remains limited. Recent studies highlight the importance of individual pre‐migration experience, but such evidence is ...

Sums of multidimensional Kloosterman sums

Periodica Mathematica Hungarica
Abstract We obtain a new bound on certain multiple sums with multidimensional Kloosterman sums. In particular, these bounds show the existence of nontrivial cancellations between such sums in very small families.

Groundwater Flow Systems as Key Determinants of Groundwater‐Dependent Vegetation Distribution

Ecohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT Direct investigations of the connection between groundwater flow systems across multiple scales and groundwater‐dependent ecosystems (GDEs) remain rare. Such studies offer valuable insights into the complex and scale‐dependent relationships between groundwater dynamics and vegetation patterns.
