A Dimension Reduction Technique for Large-scale Structured Sparse Optimization Problems with Application to Convex Clustering [PDF]

open access: yesarXiv, 2021
In this paper, we propose a novel adaptive sieving (AS) technique and an enhanced AS (EAS) technique, which are solver independent and could accelerate optimization algorithms for solving large scale convex optimization problems with intrinsic structured sparsity.

Long-range orbitofrontal and amygdala axons show divergent patterns of maturation in the frontal cortex across adolescence. [PDF]

open access: yes, 2016
The adolescent transition from juvenile to adult is marked by anatomical and functional remodeling of brain networks. Currently, the cellular and synaptic level changes underlying the adolescent transition are only coarsely understood.

Massage‐Mimicking Nanosheets Mechanically Reorganize Inter‐organelle Contacts to Restore Mitochondrial Functions in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Parkinson's disease (PD) progression is aggravated by disrupted inter‐organelle contacts, which are influenced by mechanical forces. NanoMassage, 200 nm PEGylated black phosphorus nanosheets, deliver targeted mechanical stimulation to neural cells.

The history of stereotactic technology

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2015
This paper takes an overall review on the development of stereotactic technology. During the year 1947-2015, the history of stereotactic technology can be divided into five stages: 1) frame-based and stereotactic technology (1947-1972); 2) frame-based

The Scalable Brain Atlas: instant web-based access to public brain atlases and related content [PDF]

open access: yesarXiv, 2013
The Scalable Brain Atlas (SBA) is a collection of web services that provide unified access to a large collection of brain atlas templates for different species. Its main component is an atlas viewer that displays brain atlas data as a stack of slices in which stereotaxic coordinates and brain regions can be selected.

An effective initial particle sampling technique for Monte Carlo reactor transient simulations [PDF]

open access: yesarXiv, 2023
We propose a technique to effectively sample initial neutron and delayed neutron precursor particles for Monte Carlo (MC) simulations of typical off-critical reactor transients. The technique can be seen as an improvement, or alternative, to the existing ones.

Coupling between gamma-band power and cerebral blood volume during recurrent acute neocortical seizures [PDF]

open access: yes, 2014
Characterization of neural and hemodynamic biomarkers of epileptic activity that can be measured using non-invasive techniques is fundamental to the accurate identification of the epileptogenic zone (EZ) in the clinical setting. Recently, oscillations at

Altered Neural Activity in the Mesoaccumbens Pathway Underlies Impaired Social Reward Processing in Shank3‐Deficient Rats

open access: yesAdvanced Science, EarlyView.
This study examines the effects of Shank3 mutation on the mesoaccumbens pathway using a Shank3‐deficient rat model. The findings reveal altered social reward processing in these rats, accompanied by changes in dopaminergic and GABAergic neural activity within the ventral tegmental area (VTA) and dopamine release in the nucleus accumbense (NAc ...
