Traumatic Left Anterior Descending Coronary Artery-Right Ventricle Fistula: A Case Report

Journal of Tehran University Heart Center, 2011
Traumatic coronary artery-cameral fistulas (TCAF) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. Early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery ...

Penetrating skull stab

Forensic Science, Medicine and Pathology
Abstract Fatal skull stabs are rare. In the case reported here, a 28-year-old man sustained an isolated penetrating skull injury from a knife and died two days later. The bone shard with the stab puncture, which was neurosurgically removed before death, later allowed the reproducible exact assignment of the murder knife found at the scene to ...

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

Advanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

Fish Scale-Inspired Stab-Resistant Body Armour

Materials Proceedings
While commercially available lightweight “stab-proof” apparel exists, it offers little resistance to true stabbing as it is primarily designed to withstand slash attacks. Yet, crimes involving the use of a knife or sharp instrument have consistently been

Parsing Argumentation Structures in Persuasive Essays

Computational Linguistics, 2017
In this article, we present a novel approach for parsing argumentation structures. We identify argument components using sequence labeling at the token level and apply a new joint model for detecting argumentation structures.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Improving Ionic Conformality Across Polymer Electrolyte|Electrode Interfaces

Advanced Materials, EarlyView.
Polymer electrolytes typically form physically intimate electrode interfaces but often fail to maintain continuous ionic pathways, critically limiting battery performance. Through strategic compositional design, this study introduces a molecular ionic composite electrolyte that effectively reduces interfacial ionic depletion, ensuring consistent ion ...
