On the existence of global bisections of Lie groupoids [PDF]

open access: yesActa Mathematica Sinica, English Series, 2009
We show that every source connected Lie groupoid always has global bisections through any given point. This bisection can be chosen to be the multiplication of some exponentials as close as possible to a prescribed curve. The existence of bisections through more than one prescribed points is also discussed.

A sufficient condition for global existence of solutions to a generalized derivative nonlinear Schrödinger equation [PDF]

open access: yes, 2016
We give a sufficient condition for global existence of the solutions to a generalized derivative nonlinear Schr\"{o}dinger equation (gDNLS) by a variational argument.

Global existence for the Seiberg–Witten flow [PDF]

open access: yesCommunications in Analysis and Geometry, 2010
We introduce the gradient flow of the Seiberg-Witten functional on a compact, orientable Riemannian 4-manifold and show the global existence of a unique smooth solution to the flow. The flow converges uniquely in $C^\infty$ up to gauge to a critical point of the Seiberg-Witten functional.

Clinical Correlates of Anxiety and Depression After Diagnosis of a Pediatric Brain Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The prevalence and clinical correlates of symptoms of anxiety and depression in pediatric patients with brain tumors are not well described. We aimed to identify clinical characteristics that are correlated with elevated symptoms of anxiety and depression following initial diagnosis.

What to Do When Medical Evidence Can Only Be Generated Through Routine Data: An Example From Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children undergoing allogeneic stem cell transplantation often receive off‐label rituximab treatment for Epstein–Barr virus reactivation, using adult dosing without pediatric evidence. This project aims to develop a clinical decision support tool (CDSS) that provides evidence‐based dosing scenarios by analyzing real‐world patient data.

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)

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Global existence for the derivative nonlinear Schrödinger equation by the method of inverse scattering [PDF]

open access: yes, 2015
We develop inverse scattering for the derivative nonlinear Schrödinger equation (DNLS) on the line using its gauge equivalence with a related nonlinear dispersive equation.

On the global existence of solutions to the Prandtl's system

open access: yesAdvances in Mathematics, 2004
This paper is concerned with the global existence of weak solutions to the initial boundary value problem involving a two-dimensional Prandtl's system, for unsteady boundary layer with initial data, and the pressure gradient satisfying certain conditions.
