Convex approximations for a class of mixed-integer recourse models
We consider mixed-integer recourse (MIR) models with a single recourse constraint.We relate the secondstage value function of such problems to the expected simple integer recourse (SIR) shortage function.

Long time behavior of quasi-convex and pseudo-convex gradient systems on Riemannian manifolds
, 2017 In this paper, we study the following gradient system on a complete Riemannian manifold M, {-x?(t) = grad'(x(t)) x(0) = x0, where ? : M ? R is a C1 function with Argmin ? ? ?. We prove that the gradient flow x(t) converges to a critical point of

Monotonicities of Quasi-Normed Orlicz Spaces
AxiomsIn this paper, we introduce a new Orlicz function, namely a b-Orlicz function, which is not necessarily convex. The Orlicz spaces LΦ generated by the b-Orlicz function Φ equipped with a Luxemburg quasi-norm contain both classical spaces Lp(p≥1) and Lp ...

Optimality Conditions for Semivectorial Bilevel Convex Optimal Control Problems [PDF]
We present optimality conditions for bilevel optimal control problems where the upper level, to be solved by a leader, is a scalar optimal control problem and the lower level, to be solved by several followers, is a multiobjective convex optimal control ...

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park
The Journal of Wildlife Management, EarlyView.Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

On the Fekete-Szego problem for alpha-quasi-convex functions
Tamkang Journal of Mathematics, 2000 Let $ Q_\alpha(\alpha\ge 0)$ denote the class of normalized analytic alpha-quasi-convex functions $ f$, defined in the unit disc, $ D=\{z:|z|

Optimal Lipschitzian selection operator in quasi-convex optimization
, 1987 Given a bounded real function f defined on a closed bounded real interval I, the problem is to find a quasi-convex function f′ which minimizes the supremum of ¦f(s) − f′(s)¦ for all s in I, over the class of all quasi-convex functions f′ on I.

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Static anterior tibial translation (sATT) is a reproducible monopodal weight‐bearing radiographic parameter that reflects the resting sagittal position of the tibiofemoral joint. Distinct from manual laxity tests that quantify passive displacement limits, sATT captures the functional equilibrium of the tibia under physiological load ...

MathematicsWe extend the modified BFGS algorithm to a limited-memory framework, and propose a self-adaptive limited-memory quasi-Newton method, denoted as LADBFGS, for large-scale unconstrained optimization.
