The purpose of the research discussed in this article is to explore the possibility of creating hybrid soft ballistic panel (BP) package variants by integrating into their composition layers of graphene-modified para-aramid fabrics in combinations with the different ballistic Kevlar textiles to improve the durability of the first layers of the soft ballistic panel. To address this goal, the liquid-phase exfoliation (LPE) method was used for integrating dispersions into composites to solve a number of topical problems in the stages of the technological sequence development of processing methods and optimizing processing parameters in accordance with the processing specifics of aramid textiles to achieve the desired properties of modified ballistic fabric, including the provision of coating adhesion to the surface to be modified. To test the results, ballistic experiments were performed and the back-face signature (BFS) of bullet impact on a backing material was analysed according to standards. Bullet impacts on the first ballistic protective fabric layers were also studied.

Nonequilibrium membrane pattern formation is studied using meshless membrane simulation. We consider that molecules bind to either surface of a bilayer membrane and move to the opposite leaflet by flip-flop. When binding does not modify the membrane properties and the transfer rates among the three states are cyclically symmetric, the membrane exhibits spiral-wave and homogeneous-cycling modes at high and low binding rates, respectively, as in an off-lattice cyclic Potts model.

Intelligent decisions in response to external informative input can allow organisms to achieve their biological goals while spending very little of their own resources. In this paper, we develop and study a minimal model for a navigational task, performed by an otherwise completely motorless particle that possesses the ability of hitchhiking in a bath of active Brownian particles (ABPs). Hitchhiking refers to identifying and attaching to suitable surrounding bath particles.

The guiding principles of trauma care are almost exclusively based on blunt trauma, and the management principles do not always translate. Ballistic long bone fractures, particularly of the lower extremity, can often be managed with similar principles, although the injury pattern can make restoration of anatomic alignment a challenge.

Complex limb injuries are combination injuries that involve all components of a limb's tissue, such as skin, bone with its surrounding soft tissue cover, and neurovascular elements. Complex limb trauma often has a background of a significant mechanism of injuries such as high-velocity road traffic accidents, ballistic injuries, industrial accidents, and other major mechanisms of injuries which involve high amounts of energy transfer through these tissue layers. These injuries pose a major challenge to trauma and orthopaedic surgeons.

Objective: Management of mandibular ballistic trauma is poorly delineated, given the variable injury complexity. This study examines surgical outcomes and presents a novel scoring system to define and guide the management of low-velocity ballistic mandibular fractures.
Methods: A retrospective chart review was performed from 2015 to 2022 to collect data on patients who suffered ballistic mandibular fractures.
