Optimized and Aligned Anisotropic Monte Carlo Sampling Patterns

Computer Graphics Forum, EarlyView.
Abstract Path tracing uses Monte Carlo integration to solve the rendering equation by evaluating the integrand at random sampling points. The convergence rate of the error can be significantly improved by using correlated instead of random sampling, especially on smooth integrands.

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

Physiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

New pseudorandom functions based on SIS

Tongxin xuebao, 2014
Pseudorandom functions are vital tools in the construction of cryptographic primitives.Under the hard assumption of SIS (short integer solution),two lattice-based pseudorandom functions are proposed.The first one has parallel structure by the ideal of ...

Pseudorandom sequence contention algorithm for IEEE 802.11ah based internet of things network.

PLoS ONE, 2020
The IEEE 802.11ah standard relies on the conventional distributed coordination function (DCF) as a backoff selection method. The DCF is utilized in the contention-based period of the newly introduced medium access control (MAC) mechanism, namely ...

Independent Effects of Age, Education, Verbal Working Memory, Motor Speed of Processing, Locality, and Morphosyntactic Category on Verb‐Related Morphosyntactic Production: Evidence From Healthy Aging

Topics in Cognitive Science, EarlyView.
Abstract This study investigates the role of locality (a task/material‐related variable), demographic factors (age, education, and sex), cognitive capacities (verbal working memory [WM], verbal short‐term memory [STM], speed of processing [SOP], and inhibition), and morphosyntactic category (time reference and grammatical aspect) in verb‐related ...

Vibrotactile intensity perception: Predominant influence of afferents recruited remote from stimulus site

The Journal of Physiology, EarlyView.
Abstract figure legend We delivered trains of brief mechanical pulses to the fingertips of subjects to investigate vibrotactile intensity perception. Some stimuli consisted of bursts of up to four pulses. Simulated responses of the tactile afferent population across the hand revealed that afferents innervating the skin directly under the probe reliably

Distinct effects of fibromyalgia pain, depression and anxiety on perception of affective touch and pain

The Journal of Physiology, EarlyView.
Abstract figure legend Patients with fibromyalgia (FM) and no‐pain controls completed questionnaire‐based ratings of chronic pain, childhood trauma, anxiety and depression. Brief touch stimuli were then administered, including slow brushing at the C‐tactile optimal velocity of 3 cm/s, deep oscillating pressure with a compression sleeve, roboticized ...

Bounded exponential sums with multiplicative coefficients

Mathematika, Volume 72, Issue 4, October 2026.
Abstract We investigate when the exponential sum Sf(x,α):=∑n⩽xf(n)e(nα)$S_f(x,\alpha) := \sum _{n\leqslant x}f(n)\mathrm{e}(n\alpha)$ is bounded, for a multiplicative function f$f$ and α∈R$\alpha \in \mathbb {R}$. We show that under natural assumptions, Sf(x,α)$S_f(x,\alpha)$ is bounded only when f$f$ is very close to a twisted Dirichlet character χ(n ...

Cancer Treatment and Memory in Breast Cancer Survivors: Differential Effects on Detailed Episodic and Gist‐Like Memory Recall Over Time

Hippocampus, Volume 36, Issue 5, September 2026.
ABSTRACT Breast cancer survivors (BCS) frequently experience chemotherapy‐related cognitive impairment, including episodic memory deficits. This study examined the long‐term impact of cancer treatment on memory for naturalistic events, using film clips to assess recall of central (gist‐like elements; reflects the story narrative) and peripheral ...

Short signature based on factoring problem in the standard model

Tongxin xuebao, 2011
A short signature scheme based on factoring problem in the standard model was proposed.To design this sig-nature scheme,the generic construction of fully-secure signatures from weakly-secure signatures and a chameleon hash were employed.A signature in ...
