New Insights Into Permeation of Large Cations Through ATP-Gated P2X Receptors

Frontiers in Molecular Neuroscience, 2018
The permeability of large cations through the P2X pore has remained arguably the most controversial and complicated topic in P2X-related research, with the emergence of conflicting studies on the existence, mechanism and physiological relevance of a so ...

The Eyes Have It: Sex and Sexual Orientation Differences in Pupil Dilation Patterns [PDF]

, 2012
Recent research suggests profound sex and sexual orientation differences in sexual response. These results, however, are based on measures of genital arousal, which have potential limitations such as volunteer bias and differential measures for the sexes.

Deformation mechanisms leading to auxetic behaviour in the α-cristobalite and α-quartz structures of both silica and germania [PDF]

, 2008
Analytical expressions have been developed in which the elastic behaviour of the α-quartz and α-cristobalite molecular tetrahedral frameworks of both silica and germania are modelled by rotation, or dilation or concurrent rotation and dilation of the ...

Dilated Semantic Segmentation for Breast Ultrasonic Lesion Detection Using Parallel Feature Fusion

Diagnostics, 2021
Breast cancer is becoming more dangerous by the day. The death rate in developing countries is rapidly increasing. As a result, early detection of breast cancer is critical, leading to a lower death rate.

Standard noncommuting and commuting dilations of commuting tuples [PDF]

, 2002
We introduce a notion called `maximal commuting piece' for tuples of Hilbert space operators. Given a commuting tuple of operators forming a row contraction there are two commonly used dilations in multivariable operator theory.

The Effects of Dilation Technique in Percutaneous Nephrolithotomy: One-Shot Versus Sequential Dilation

Boğaziçi Tıp Dergisi, 2022
INTRODUCTION: In this study, the authors aimed to compare the results of one-shot dilation (OD) and sequential dilation (SD) techniques which are used to access in patients who had undergone percutaneous nephrolithotomy (PCNL).

Outcomes of Dilation of Recalcitrant Pancreatic Strictures Using a Wire-Guided Cystotome [PDF]

Clinical Endoscopy, 2021
Background/Aims Pancreatic strictures in chronic pancreatitis are treated using endoscopic retrograde cholangiopancreatography (ERCP) with plastic stent placement. The management of recalcitrant strictures remains a challenge, with the use of a Soehendra

A theoretical insight into morphological operations in surface measurement by introducing the slope transform [PDF]

, 2015
As one of the tools for surface analysis, morphological operations, although not as popular as linear convolution operations (e.g. the Gaussian filter), are really useful in mechanical surface reconstruction, surface filtration, functional simulation etc.

Structure of the Granitic Pegmatite Field of the Northern Coast of Portugal—Inner Pegmatite Structures and Mineralogical Fabrics

Heritage, 2019
On the coastline of Northern Portugal, metamorphic formations and pegmatites were the subject of structural analysis with the main goal of understanding Variscan kinematics and related pegmatite intrusion. This study also aims to discriminate, select and
