Reliability and interobserver variability of a grading system of ventricular distension in dogs

open access: yesFrontiers in Veterinary Science, 2023
IntroductionInternal hydrocephalus is the most common malformation of the central nervous system in dogs. Although the grades of ventricular distension have importance for long-term prognosis, there is no standard classification scheme describing the ...

On the existence and design of functional observers for linear systems

open access: yes, 2007
Darouach [1] recently derived necessary and sufficient conditions for the existence and stability of functional observers with an order, p, equals to the dimension m of the vectors to be estimated.

Separable mechanisms underlying global feature-based attention [PDF]

open access: yes, 2012
Feature-based attention is known to operate in a spatially global manner, in that the selection of attended features is not bound to the spatial focus of attention.

Recovering Gradients from Sparsely Observed Functional Data [PDF]

open access: yesBiometrics, 2013
AbstractSummaryThe recovery of gradients of sparsely observed functional data is a challenging ill‐posed inverse problem. Given observations of smooth curves (e.g., growth curves) at isolated time points, the aim is to provide estimates of the underlying gradients (or growth velocities). To address this problem, we develop a Bayesian inversion approach

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Intra- and interobserver agreement in the diagnosis of malocclusion in sleep-disordered breathing

open access: yesArquivos de Neuro-Psiquiatria, 2014
Sleep-disordered breathing (SDB) is often related to malocclusion, and dentists should be able to recognize occlusal changes that may be associated with the development, onset, or persistence of SDB.

The power of tears: Observers’ brain responses show that tears provide unambiguous signals independent of scene context

open access: yesNeuroImage: Reports, 2022
Only humans produce emotional tears, a fact that has been linked to triggering empathy, social bonding, and providing support in observers. Consequently, either the tears themselves play a crucial role in eliciting such behavior, or, alternatively, the ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Learning about threat from friends and strangers is equally effective: An fMRI study on observational fear conditioning

open access: yesNeuroImage, 2022
Humans often benefit from social cues when learning about the world. For instance, learning about threats from others can save the individual from dangerous first-hand experiences. Familiarity is believed to increase the effectiveness of social learning,
