An Optimal Spectral Inequality for Degenerate Operators
SIAM Journal on Control and OptimizationIn this paper we establish a Lebeau-Robbiano spectral inequality for a degenerate one dimensional elliptic operator. Carleman techniques and moment method are combined. Application to null controllability on a measurable set in time for the degenerated heat equation is described.

Arthritis &Rheumatology, EarlyView.Objective Polymyalgia rheumatica (PMR) is a common indication for long‐term glucocorticoid (GC) treatment. Bone‐protective and gastroprotective medications are recommended for those at high risk of adverse events from GCs, but no trials have evaluated their effectiveness in PMR.

Optimal weighted Wente’s inequality
Communications in Partial Differential EquationsWe prove $L^\infty$ and $W^{1,2}$ weighted Wente's inequalities. We prove in particular the critical case: for the $|x|^2$ weighted Wente's estimate the optimal weight is $|x|^2\log|x|$.

Anatomical Sciences Education, EarlyView.Abstract The introduction of new educational technologies into resource‐challenged learning environments is often hindered by several factors, with the lack of infrastructure and computer hardware being only one critical aspect. The COVID‐19 pandemic required a sudden switch to online learning and accelerated the implementation of e‐learning approaches

Entropy, 2019 The well-known Hölder’s inequality has been recently utilized as an essential tool for solving several optimization problems. However, such an essential role of Hölder’s inequality does not seem to have been reported in the context ...

WEALTH INEQUALITY AND OPTIMAL MONETARY POLICY [PDF]
Macroeconomic Dynamics, 2010 We study the money-in-the-utility-function model in which agents are heterogeneous in their initial wealth. We show that the Friedman rule is not optimal even if the government uses nonlinear income taxation for redistribution. A positive nominal interest rate raises social welfare because it relaxes the incentive compatibility constraint for highly ...

Set Optimization Meets Variational Inequalities [PDF]
, 2015 We study necessary and sufficient conditions to attain solutions of set-optimization problems in therms of variational inequalities of Stampacchia and Minty type. The notion of a solution we deal with has been introduced Heyde and Loehne, for convex set-valued objective functions.

Risk‐aware safe reinforcement learning for control of stochastic linear systems
Asian Journal of Control, EarlyView.Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...
