Asymptotic Estimates of the Solution of a Restoration Problem with an Initial Jump

Journal of Applied Mathematics, 2014
The asymptotic behavior of the solution of the singularly perturbed boundary value problem Lεy=htλ,Liy+σiλ=ai,i=1,n+1̅ is examined. The derivations prove that a unique pair (ỹt,λ̃ε,ε,λ̃ε) exists, in which components y(t,λ̃ε,ε) and λ̃(ε) satisfy the ...

Dirac Equation with External Potential and Initial Data on Cauchy Surfaces [PDF]

, 2014
With this paper we provide a mathematical review on the initial-value problem of the one-particle Dirac equation on space-like Cauchy hypersurfaces for compactly supported external potentials.

Cognitive Functioning in Vorinostat‐Treated Pediatric and Young Adult Patients Over the First 180 Days After Hematopoietic Stem Cell Transplant

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Cognitive and psychological difficulties could negatively interfere with treatment adherence and quality of life before and after hematopoietic stem cell transplant (HSCT). Methods to mitigate these changes may have positive effects on treatment success.

Hybrid solution method for ultra-wideband positioning in coal mines

Gong-kuang zidonghua, 2021
Ultra-wideband positioning is based on the marked point distance measured by the base station and a set of non-linear positioning equations to obtain the precise device position by applying Taylor series expansion algorithm, Chan algorithm or least ...

Blow-Up of Positive Solutions to Wave Equations in High Space Dimensions [PDF]

, 2014
This paper is concerned with the Cauchy problem for the semilinear wave equation: $u_{tt}-\Delta u=F(u) \ \mbox{in} \ R^n\times[0, \infty)$, where the space dimension $n \ge 2$, $F(u)=|u|^p$ or $F(u)=|u|^{p-1}u$ with $p>1$.

Nonlinear initial-value problems with positive global solutions

Electronic Journal of Differential Equations, 2003
Summary: We give conditions on \(m(t)\), \(p(t)\), and \(f(t,y,z)\) so that the nonlinear initial value problem \[ \frac{1}{m(t)} (p(t)y')'+ f(t,y,p(t)y')=0\quad\text{for }t>0,\quad y(0)=0, \quad \lim_{t\to 0^+} p(t)y'(t)= B, \] has at least one positive solution for all \(t>0\), when \(B\) is a sufficiently small positive constant.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Calibration of a Manipulator With a Regularized Parameter Identification Method

IEEE Access, 2022
As an inverse problem, the parameter identification of manipulators is essential to in-situ calibration. Since the ill-posed inverse kinematic model is sensitive to the measurement value, even tiny errors will make the geometric model of the manipulator ...

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

Molecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.
