Quantum Phase Transition as a Promising Route to Enhance the Critical Current in Kagome Superconductor CsVSb.

Developing strategies to systematically increase the critical current, the threshold current below which the superconductivity exists, is an important goal of materials science. Here, the concept of quantum phase transition is employed to enhance the critical current of a kagome superconductor CsVSb, which exhibits a charge density wave (CDW) and superconductivity that are both affected by hydrostatic pressure. As the CDW phase is rapidly suppressed under pressure, a large enhancement in the self-field critical current (I) is recorded.

Large Fermi surface in pristine kagome metal CsVSb and enhanced quasiparticle effective masses.

The kagome metal CsV[Formula: see text]Sb[Formula: see text] is an ideal platform to study the interplay between topology and electron correlation. To understand the fermiology of CsV[Formula: see text]Sb[Formula: see text], intensive quantum oscillation (QO) studies at ambient pressure have been conducted. However, due to the Fermi surface reconstruction by the complicated charge density wave (CDW) order, the QO spectrum is exceedingly complex, hindering a complete understanding of the fermiology.

Association of circadian rhythm with mild cognitive impairment among male pneumoconiosis workers in Hong Kong: a cross-sectional study.

Weakened circadian activity rhythms (CARs) were associated with mild cognitive impairment (MCI) in the general population. However, it remains unclear among pneumoconiosis patients. We aimed to address this knowledge gap.

Nodeless Superconductivity in Kagome Metal CsVSb with and without Time Reversal Symmetry Breaking.

The kagome metal CsVSb features an unusual competition between the charge-density-wave (CDW) order and superconductivity. Evidence for time reversal symmetry breaking (TRSB) inside the CDW phase has been accumulating. Hence, the superconductivity in CsVSb emerges from a TRSB normal state, potentially resulting in an exotic superconducting state.

Gamma knife radiosurgery versus deep brain stimulation for treatment-refractory depression and obsessive-compulsive disorder: A brief comparative summary.

Both gamma knife surgery (GKS) and deep brain stimulation (DBS) have documented success in management of treatment-refractory major depressive disorder (MDD) and obsessive-compulsive disorder (OCD), but there are no formal randomized controlled trials to compare these treatment modalities in cases of psychiatric illnesses. In this brief review, comparison of GKS and DBS for management of MDD and OCD was done with regard to their efficacy, accompanying risks, reversibility of therapeutic effects, costs, availability, and daily life issues. Currently available evidence does not support the superiority of either evaluated treatment modality over each other in terms of clinical efficacy in cases of MDD and OCD.

Differences in Sleep Patterns and Mental Health Problems During Different Periods of COVID-19 Outbreak Among Community-Dwelling Older Men in Hong Kong.

To determine the association of sleep with mental health among Hong Kong community-dwelling older men in the context of the COVID-19 pandemic. This additional analysis was derived from the community-dwelling men aged >60 recruited during three COVID-19 outbreaks (i.e.

A Nurse-Led Education Program for Pneumoconiosis Caregivers at the Community Level.

Pneumoconiosis is an irreversible chronic disease. With functional limitations and an inability to work, pneumoconiosis patients require support from family caregivers. However, the needs of pneumoconiosis caregivers have been neglected.

De novo arteriovenous shunts after endovascular cure of cerebrospinal macro arteriovenous fistulas. A role for the vasa vasorum?

Background And Purpose: Macro-arteriovenous fistulas (MAVFs) are arteriovenous shunts draining into a giant venous ectasia. They can be treated by surgery or embolisation. Angiographic controls are usually performed rapidly after treatment in order to prove the cure of the lesion but no long term angiographies are generally scheduled.

Per-region interobserver agreement of Alberta Stroke Program Early CT Scores (ASPECTS).

Background And Purpose: The Alberta Stroke Program Early CT Score (ASPECTS) is a commonly used scoring system to select patients with stroke for endovascular treatment (EVT). However, the inter- and intra-reader variability is high.

Objective: To determine whether the inter- and intra-reader variability is different for various regions of the ASPECTS scoring system by evaluating the interobserver variability of ASPECTS between different readers in a per-region analysis.

Republished: Transradial approach in the treatment of a sacral dural arteriovenous fistula: a technical note.

Sacral dural arteriovenous fistulas (SDAVFs) are rare, constituting no more than 10% of all spinal dural fistulas. They are most commonly fed by the lateral sacral artery (LSA), a branch of the internal iliac artery (IIA). Catheterization of this vessel requires either a crossover at the aortic bifurcation in cases of right femoral access or retrograde catheterization from the ipsilateral common femoral artery.

Ruptured Duplicated Middle Cerebral Artery Aneurysm Successfully Treated by Coil Embolization with Balloon Remodeling.

A duplicated middle cerebral artery (dMCA) is a rare anatomical variant that can be associated with aneurysm formation and rupture. The dMCA arises from the terminal portion of the internal carotid artery, with the caudal trunk supplying the temporal lobe and the cranial trunk supplying the frontal lobe and the lenticulostriate perforators. Previous reported cases were all treated with open surgical clipping with or without cerebral revascularization to reconstruct the dMCA.

The application of point-of-care platelet function assay in guiding platelet transfusion in aspirin-users with intracranial haemorrhages.

Background: An increasing number of patients with intracranial haemorrhages are aspirin-users. Neurosurgeons commonly attempt to minimize the risk of re-bleeding by withholding the medication and giving platelet transfusion. However, recent studies raised safety concerns and showed poorer outcome with platelet transfusion when the latter was not guided by changes in platelet function.

Orbital Infarction Syndrome Following Mechanical Thrombectomy Secondary to Embolization in New Territory.

Background: Orbital infarction syndrome (OIS) is a rare entity defined as ischemia of all intraorbital and intraoccular structures including the optic nerve, extraocular muscles, and orbital fat. This entity is rare due to rich anastomotic orbital vascularization from both the internal carotid artery and external carotid artery. We report a case of a patient who suffered emboli to previously nonaffected territories to the ophthalmic artery and external carotid artery, which resulted in orbital infarction syndrome, and describe techniques to avoid such complications.

Highly stable porous silicon-carbon composites as label-free optical biosensors.

A stable, label-free optical biosensor based on a porous silicon-carbon (pSi-C) composite is demonstrated. The material is prepared by electrochemical anodization of crystalline Si in an HF-containing electrolyte to generate a porous Si template, followed by infiltration of poly(furfuryl) alcohol (PFA) and subsequent carbonization to generate the pSi-C composite as an optically smooth thin film. The pSi-C sensor is significantly more stable toward aqueous buffer solutions (pH 7.

Selective removal of the outer shells of anodic TiO2 nanotubes.

A facile electrochemical method to selectively remove the outer walls of anodic TiO(2) nanotubes by leaving the as-anodized nanotubes in the same electrolyte and applying an electric field parallel to the anodic film for several minutes is reported. The better-separated single-walled TiO(2) nanotubes thus obtained show significantly improved photocatalytic efficiency compared with their non-etched counterparts.

TiO2-based nano-wells for fabricating nanocrystals.

This paper reports a convenient bottom-up method to fabricate robust and inert TiO2-based nanowells for growing nanocrystals. These TiO2-based nanowells are fabricated in three steps: fabricating a thin film of self-organized TiO2 nanotubes by the convenient electrochemical anodization method (Step 1), striping the fabricated nanotube thin film to expose the ordered array of nanowells underneath (Step 2), and surface modifying the exposed nanowells to adjust their surface hydrophobicity and hydrophilicity (Step 3). These fabricated nanowells can then be used to template the growth of an ordered array of nanocrystals by trapping a tiny droplet of precursor solution inside each nanowell.

The role of the N-domain in the ATPase activity of the mammalian AAA ATPase p97/VCP.

p97/valosin-containing protein (VCP) is a type II ATPase associated with various cellular activities that forms a homohexamer with each protomer containing an N-terminal domain (N-domain); two ATPase domains, D1 and D2; and a disordered C-terminal region. Little is known about the role of the N-domain or the C-terminal region in the p97 ATPase cycle. In the p97-associated human disease inclusion body myopathy associated with Paget disease of bone and frontotemporal dementia, the majority of missense mutations are located at the N-domain D1 interface.

Dissociation of alkaliated alanine in the gas phase: the role of the metal cation.

The dissociation of prototypical metal-cationized amino acid complexes, namely, alkaliated alanine ([Ala+M]+, M+ = Li+, Na+, K+), was studied by energy-resolved tandem mass spectrometry with an ion-trap mass analyzer and by density functional theory. Dissociation leads to formation of fragment ions arising from the loss of small neutrals, such as H2O, CO, NH3, (CO+NH3), and the formation of Na+/K+. The order of appearance threshold voltages for different dissociation pathways determined experimentally is consistent with the order of critical energies (energy barriers) obtained theoretically, and this provides the necessary confidence in both experimental and theoretical results.

Competition between pi and non-pi cation-binding sites in aromatic amino acids: a theoretical study of alkali metal cation (Li+, Na+, K+)-phenylalanine complexes.

To understand the cation-pi interaction in aromatic amino acids and peptides, the binding of M(+) (where M(+) = Li(+), Na(+), and K(+)) to phenylalanine (Phe) is studied at the best level of density functional theory reported so far. The different modes of M(+) binding show the same order of binding affinity (Li(+)>Na(+)>K(+)), in the approximate ratio of 2.2:1.
