First Detection and Tunneling Time of a Quantum Walk
Entropy, 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
Journal 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]
Physical 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.

A continuous time model for observer-based frequency tracking
Results 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.

Duality for pathwise superhedging in continuous time [PDF]
, 2019 We provide a model-free pricing-hedging duality in continuous time. For a frictionless market consisting of $d$ risky assets with continuous price trajectories, we show that the purely analytic problem of finding the minimal superhedging price of a path ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric 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.

Pediatric 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.

Pediatric 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 ...

Large Deviations for Continuous Time Random Walks
Entropy, 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.
