Management of Bullet Emboli to the Heart and Great Vessels.
Military Medicine, 2018 Introduction Firearm-related injuries account for 20% of all injury-related deaths and are responsible for 105,000 injuries annually. The occurrence of bullet emboli to the heart is exceedingly rare.

Simplicial resolutions and Ganea fibrations [PDF]
, 2007 In this work, we compare the two approximations of a path-connected space $X$, by the Ganea spaces $G_n(X)$ and by the realizations $\|\Lambda_\bullet X\|_{n}$ of the truncated simplicial resolutions emerging from the loop-suspension cotriple $\Sigma ...

The Journal of Cell Biology, 2001 A switch from intramolecular to intermolecular disulfide bonds helps Hydra and related jellyfish to construct a capsule of enormous strength, according to a team of zoologists and biochemists. Figure The minicollagen antibody (red) detects nematocysts (green) only in their immature form, before intermolecular disulfides form ...

Aerodynamic Characterization of Bullet Heads with Different Arcuate Curves [PDF]
Journal of Applied Fluid MechanicsThe bullet shape is critical in efficient bullet design because it affects the lift and drag forces. This paper proposes a new bullet shape with a logarithmic curve and analyzes the lift and drag coefficients of bullets with different curves under ...

New Hopf Structures on Binary Trees [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 The multiplihedra $\mathcal{M}_{\bullet} = (\mathcal{M}_n)_{n \geq 1}$ form a family of polytopes originating in the study of higher categories and homotopy theory. While the multiplihedra may be unfamiliar to the algebraic combinatorics community, it is

Acoustic methods for measuring bullet velocity
, 2008 This article describes two acoustic methods to measure bullet velocity with an accuracy of 1% or better. In one method, a microphone is placed within 0.1 m of the gun muzzle and a bullet is fired at a steel target 45 m away.

On the idempotent semirings such that $\mathcal{D}^\bullet$ is the least distributive lattice congruence [PDF]
arXiv, 2017 Here we describe the least distributive lattice congruence $\eta$ on an idempotent semiring in general and characterize the varieties $D^\bullet, L^\bullet$ and $R^\bullet$ of all idempotent semirings such that $\eta=\mathcal{D}^\bullet, \mathcal{L}^\bullet$ and $\mathcal{R}^\bullet$, respectively.
