Construction and analysis of one class of cryptographic functions

Tongxin xuebao, 2013
A novel class of n+t -variable Boolean functions G (x,y) through adding t variables while concatenating t+ 1 Boolean functions (called basic function) was constructed and the Walsh spectrum and autocorrelation coefficient of G(x,y)were given.The ...

Astigmatic changes after Descemet membrane endothelial keratoplasty (DMEK) in decompensated penetrating keratoplasty grafts

Acta Ophthalmologica, Volume 104, Issue 5, Page e516-e529, August 2026.
Abstract Purpose To evaluate the surgery‐induced changes of astigmatism after Descemet membrane endothelial keratoplasty (DMEK) in eyes with failed previous penetrating keratoplasty (PK). Design Retrospective, interventional cohort study based on prospective DMEK database.

Construction of 1-Resilient Boolean Functions with Optimal Algebraic Immunity and Good Nonlinearity [PDF]

, 2010
This paper presents a construction for a class of 1-resilient functions with optimal algebraic immunity on an even number of variables. The construction is based on the concatenation of two balanced functions in associative classes. For some n, a part of

Random Chemostats with Competition and Different Kinetics to Investigate the Growth of the Gut Microbiome

Mathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 12102-12115, 30 July 2026.
ABSTRACT We investigate some chemostat models incorporating wall growth, competition, random fluctuations on the dilution rate, and different consumption functions (Monod and Haldane). We analyze the asymptotic behavior of the solutions of the corresponding random differential systems to establish conditions on the model parameters under which the ...

Annihilators and Algebraic Immunity of Symmetric Boolean Functions

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011
In this paper, we deal with the algebraic immunity of the symmetric Boolean functions. The algebraic immunity is a property which measures the resistance against the algebraic attacks on symmetric ciphers. It is well known that the algebraic immunity of the symmetric Boolean functions is completely determined by a narrow class of annihilators with low ...

Glymphatic dysfunction couples with cortical excitation–inhibition imbalance in epilepsy: Evidence from Rasmussen encephalitis

Epilepsia, Volume 67, Issue 7, Page 3563-3576, July 2026.
Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

A Mixture of Distributed Lag Non‐Linear Models to Account for Spatially Heterogeneous Exposure‐Lag‐Response Associations

Statistics in Medicine, Volume 45, Issue 15-17, July 2026.
ABSTRACT Environmental exposures, such as air pollution and extreme temperatures, have complex effects on human health. These effects are often characterized by non‐linear exposure‐lag‐response relationships and delayed impacts over time. Accurately capturing these dynamics is crucial for informing public health interventions.

An Infinite Class of Balanced Functions with Optimal Algebraic Immunity, Good Immunity to Fast Algebraic Attacks and Good Nonlinearity [PDF]

, 2008
After the improvement by Courtois and Meier of the algebraic attacks on stream ciphers and the introduction of the related notion of algebraic immunity, several constructions of infinite classes of Boolean functions with optimum algebraic immunity have been proposed.

The effects of breath holding during high‐intensity land‐based ergometry in swimmers

Physiological Reports, Volume 14, Issue 13, July 2026.
Abstract The aim of this study was to compare cardiorespiratory responses during high‐intensity land‐based exercise between free‐breathing and breath‐holding conditions in swimmers. Twenty varsity swimmers (20 ± 2 years, 10 females) performed 20 s bouts of simultaneous arm and leg ergometry exercise at high intensity (total power output = 606 ± 76 W ...
