Nonsurgical Management of Simultaneous Double Lateral Root Perforations in Adjacent Teeth Using CBCT and MTA: A Case Report [PDF]

Case Reports in Dentistry
Lateral root perforations are serious iatrogenic complications that can compromise the outcome of endodontic treatment. The current case report presents the successful treatment of simultaneous double lateral root perforations in the mandibular canine ...

Clinical Significance of Mesiobuccal and Distobuccal Canal Variations in Maxillary Molars: A Case Series and a Mini Review [PDF]

Case Reports in Dentistry
Endodontic treatment success is contingent upon the comprehensive identification and management of all root canals within a tooth's complex anatomy. This is particularly challenging in maxillary molars, which exhibit significant variability in canal ...

Set-valued optimization problems via second-order contingent epiderivative [PDF]

Yugoslav Journal of Operations Research, 2021
In this paper, we establish second-order KKT conditions of a set-valued optimization problem and study second-order Mond-Weir, Wolfe, and mixed types duals with the help of second-order contingent epiderivative and second-order generalized cone convexity

Sufficiency and duality of set-valued fractional programming problems via second-order contingent epiderivative [PDF]

Yugoslav Journal of Operations Research, 2022
In this paper, we establish second-order sufficient KKT optimality conditions of a set-valued fractional programming problem under second-order generalized cone convexity assumptions.

Using ρ-cone arcwise connectedness on parametric set-valued optimization problems

Journal of Inequalities and Applications, 2022
Within the inquiry about work, we explore a parametric set-valued optimization problem, where the objective as well as constraint maps are set-valued.

On Constrained Set-Valued Semi-Infinite Programming Problems with ρ-Cone Arcwise Connectedness

Axioms, 2021
In this paper, we establish sufficient Karush–Kuhn–Tucker (for short, KKT) conditions of a set-valued semi-infinite programming problem (SP) via the notion of contingent epiderivative of set-valued maps. We also derive duality results of Mond–Weir (MWD),

Stationary Condition for Borwein Proper Efficient Solutions of Nonsmooth Multiobjective Problems with Vanishing Constraints

Mathematics, 2022
This paper discusses optimality conditions for Borwein proper efficient solutions of nonsmooth multiobjective optimization problems with vanishing constraints. A new notion in terms of contingent cone and upper directional derivative is introduced, and a

Contingent Cones to Reachable Sets of Control Systems [PDF]

SIAM Journal on Control and Optimization, 1989
The author considers the following control problem in \({\mathbb{R}}^ n:\) minimize g(x(T)) over the solutions to the control system \(x'(t)=f(x(t),u(t))\) a.e. in [0,T], u(t)\(\in U\) is measurable selection, x(0)\(\in C.\) Let R(t,C) denote its reachable set at time t from the set of initial conditions \(C\subset {\mathbb{R}}^ n\) and \(T_{R(t,C)}(x_
