Hypoellipticity and Higher Order Levi Conditions

open access: yes, 2014
We study the $C^\infty$-hypoellipticity for a class of double characteristic operators with simplectic characteristic manifold, in the case the classical condition of minimal loss of derivatives is ...

Implementing Health‐Related Quality of Life Assessment in Pediatric Oncology: A Feasibility Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background There is growing interest in embedding health‐related quality of life (HRQoL) assessment and patient‐reported outcome measures (PROMs) within clinical cancer care. This study evaluated the feasibility, acceptability, and usability of implementing an electronic PROM (ePROM) platform to measure HRQoL in children with cancer ...

An approach for minimal surface family passing a curve

open access: yes, 2014
We investigate minimal surfaces passing a given curve in $R^{3}$. Using the Frenet frame of a given curve and isothermal parameter, we derive the necessary and sufficient condition for minimal surface.

A Strict Minimal Siphon-Based Necessary and Sufficient Condition for Liveness Verification in General Petri Nets

open access: yesIEEE Access
To describe deadlocks occurring in general nets, some characterizations have been proposed to establish a relationship between liveness and siphons. Among them, the most prominent characterizations are max-controlled siphons and deadly marked siphons ...

Integrable and continuous solutions of a nonlinear quadratic integral equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
We are concerned here with a nonlinear quadratic integral equation of Volterra type. The existence of at least one $L_1-$ positive solution will be proved under the Carath\`{e}odory condition.

Minimal period problem for second-order Hamiltonian systems with asymptotically linear nonlinearities

open access: yesOpen Mathematics, 2022
By applying the combination of discrete variational method and approximation, developed in a previous study [J. Kuang, W. Chen, and Z. Guo, Periodic solutions with prescribed minimal period for second-order even Hamiltonian systems, Commun.

Logarithmic minimal models with Robin boundary conditions [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2016
We consider general logarithmic minimal models ${\cal LM}(p,p')$, with $p,p'$ coprime, on a strip of $N$ columns with the $(r,s)$ Robin boundary conditions introduced by Pearce, Rasmussen and Tipunin. The associated conformal boundary conditions are labelled by the Kac labels $r\in{\Bbb Z}$ and $s\in{\Bbb N}$.

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

On the minimal number of periodic orbits on some hypersurfaces in $\mathbb{R}^{2n}$

open access: yes, 2016
We study periodic orbits on a nondegenerate dynamically convex starshaped hypersurface in $\mathbb{R}^{2n}$ along the lines of Long and Zhu, but using properties of the $S^1$-equivariant symplectic homology.
