Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice
Aging and Cancer, EarlyView.Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.

Backstepping Control of the One-Phase Stefan Problem
, 2016 In this paper, a backstepping control of the one-phase Stefan Problem, which is a 1-D diffusion Partial Differential Equation (PDE) defined on a time varying spatial domain described by an ordinary differential equation (ODE), is studied. A new nonlinear

Characterization of a subclass of Tweedie distributions by a property of generalized stability [PDF]
, 2010 We introduce a class of distributions originating from an exponential family and having a property related to the strict stability property. A characteristic function representation for this family is obtained and its properties are investigated.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

Exponential Stability of Switched Positive Homogeneous Systems
Complexity, 2017 This paper studies the exponential stability of switched positive nonlinear systems defined by cooperative and homogeneous vector fields. In order to capture the decay rate of such systems, we first consider the subsystems.

Exponential and sub-exponential stability times for the NLS on the circle
Rendiconti Lincei, Matematica e Applicazioni, 2019 In this note we study stability times for a family of parameter dependent nonlinear Schrödinger equations on the circle, close to the origin. Imposing a suitable Diophantine condition (first introduced by Bourgain), we state a rather flexible Birkho¤ Normal Form theorem, which implies, e.g., exponential and sub-exponential time estimates in the Sobolev

Adaptive stabilization with exponential decay [PDF]
Systems & Control Letters, 1990 Abstract Adaptive high gain stabilizers for classes of linear time-invariant state space systems are presented. The classes cover multi-input—multi-output systems where the state dimension is not known. Only standard assumptions such as minimum phase and known respectively unknown sign are required.

Dynamics of the Exponential Population Growth System with Mixed Fractional Brownian Motion
Complexity, 2021 This paper examines the dynamics of the exponential population growth system with mixed fractional Brownian motion. First, we establish some useful lemmas that provide powerful tools for studying the stochastic differential equations with mixed ...
