First Detection and Tunneling Time of a Quantum Walk

open access: yesEntropy, 2023
We consider the first detection problem for a one-dimensional quantum walk with repeated local measurements. Employing the stroboscopic projective measurement protocol and the renewal equation, we study the effect of tunneling on the detection time ...

Continuous Time Matrix Programming

open access: yesJournal of Mathematical Analysis and Applications, 1993
Duality and saddlepoint conditions are considered for the following pair of problems: \[ \max\int^ T_ 0 A(t)X(t)dt\qquad\text{subject to}\tag{P} \] \[ B(t)X(t)\leq C(t)+\int^ t_ 0 K(t,s)X(t)ds\quad\text{a.e. in }[0,T],\quad X(t)\geq 0\quad\text{a.e.

Evanescent continuous-time random walks [PDF]

open access: yesPhysical Review E, 2013
We study how an evanescence process affects the number of distinct sites visited by a continuous time random walker in one dimension. We distinguish two very different cases, namely, when evanescence can only occur concurrently with a jump, and when evanescence can occur at any time.

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Large Deviations for Continuous Time Random Walks

open access: yesEntropy, 2020
Recently observation of random walks in complex environments like the cell and other glassy systems revealed that the spreading of particles, at its tails, follows a spatial exponential decay instead of the canonical Gaussian.

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Continuous-time statistics and generalized relaxation equations [PDF]

open access: yes, 1995
Using two simple examples, the continuous-time random walk as well as a two state Markov chain, the relation between generalized anomalous relaxation equations and semi-Markov processes is illustrated.

Evaluating the Utility of Paired Tumor and Germline Targeted DNA Sequencing for Pediatric Oncology Patients: A Single Institution Report

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate the diagnostic yield and utility of universal paired tumor–normal multigene panel sequencing in newly diagnosed pediatric solid and central nervous system (CNS) tumor patients and to compare the detection of germline pathogenic/likely pathogenic variants (PV/LPVs) against established clinical referral criteria for cancer ...

A continuous time model for observer-based frequency tracking

open access: yesResults in Control and Optimization, 2023
Frequency tracking has been the focus of several research works for decades. One common method is to utilize a state observer to dynamically estimate the frequency of the measured signal.
