A QPTAS for stabbing rectangles [PDF]
arXiv, 2021 We consider the following geometric optimization problem: Given $ n $ axis-aligned rectangles in the plane, the goal is to find a set of horizontal segments of minimum total length such that each rectangle is stabbed. A segment stabs a rectangle if it intersects both its left and right edge.

Fixed-parameter tractability and lower bounds for stabbing problems [PDF]
Computational Geometry, Theory and Applications 46 (2013),
839-860. Special issue for the 25th European Workshop on Computational
Geometry (EuroCG'09), 2009 We study the following general stabbing problem from a parameterized complexity point of view: Given a set $\mathcal S$ of $n$ translates of an object in $\Rd$, find a set of $k$ lines with the property that every object in $\mathcal S$ is ''stabbed'' (intersected) by at least one line. We show that when $S$ consists of axis-parallel unit squares in $

Stabbing Pairwise Intersecting Disks by Five Points [PDF]
Discrete Mathematics (DM), 334(7), 2021, Article 112403, 2018 Suppose we are given a set $\mathcal{D}$ of $n$ pairwise intersecting disks in the plane. A planar point set $P$ stabs $\mathcal{D}$ if and only if each disk in $\mathcal{D}$ contains at least one point from $P$. We present a deterministic algorithm that takes $O(n)$ time to find five points that stab $\mathcal{D}$.

Obesity may not be protective in abdominal stab wounds
Journal of Emergencies, Trauma and Shock, 2019 Context: Current protocols for the management of abdominal stab wounds were established based on retrospective data from prior decades. Few have investigated whether higher body mass index (BMI) affects outcomes after these injuries.

Broken Knife Blade Completely Penetrating the Humerus: A Case Report and Literature Review [PDF]
Bulletin of Emergency and Trauma, 2020 We present a case of a 23-year-old male patient who presented with a blade knife completely wedged and penetrated on his humerus after a stab wound to his left upper extremity. On palpation, a foreign body was palpated under the skin on the deltoid area.
