Determination of the one‐electron reduced Wigner function for a molecular crystal

Acta Crystallographica Section A, EarlyView.
The first reconstruction of an experimental one‐particle reduced Wigner function for electrons in molecular crystals is reported. It relies on an ensemble N‐representable model jointly refined from the X‐ray diffraction and Compton scattering data.The Wigner function provides a complete phase‐space representation of a quantum state.

Research on the creation of new UD laminates and its ballistic performance using CSC aramid yarns via experiment and FEA analysis

Journal of Industrial Textiles
In this paper, a new type of core-spun compound aramid yarn has been applied in the construction of UD fabric to investigate if the ballistic performance of the whole fabric could be positively influenced.

Ballistic Limit of High-Strength Steel and Al7075-T6 Multi-Layered Plates Under 7.62-mm Armour Piercing Projectile Impact

Latin American Journal of Solids and Structures
This paper presents the computational-based ballistic limit of laminated metal panels comprised of high strength steel and aluminium alloy Al7075-T6 plate at different thickness combinations to necessitate the weight reduction of existing armour steel ...

Preparing to Fight the ‘Wrong War’? Why the UK Defence Budget Must Focus More on ‘National Resilience’

The Political Quarterly, EarlyView.
Abstract This article argues that the current debate over defence spending in the United Kingdom is fundamentally flawed. Too much emphasis is being placed on preparing for a form of warfare with Russia that is unlikely to occur. As this article points out, the Russians actually want to avoid a traditional battlefield confrontation with NATO.

A comparison of three post-activation potentiation enhancement warm up strategies on bench press performance

Frontiers in Sports and Active Living
BackgroundAt loads greater than 80% of one repetition maximum in bench press, at the ascending phase of the movement, the barbell decelerates or stops for a short time before it accelerates again during a region named sticking region.

3D‐printed wound channels

Journal of Forensic Sciences, EarlyView.
Abstract Although soft tissue simulants are widely used in ballistic research, glycerine soap is the only material that offers a clear view of the temporary cavity of a wound channel without the use of optical apparatus. However, the latter still shows some inconvenience mostly on its weight and its dehydration process when cut, making it challenging ...

A hybrid approach of NiP coating and STF impregnation of UHMWPE fabric for conductive soft body armor

Journal of Materials Research and Technology
To enhance the ballistic impact performance and impart electrical conductivity into soft armor material made up of UHMWPE fabric, a novel hybrid technique has been devised and incorporated.

Thermal persistence and physicochemical modification of inorganic gunshot residue (IGSR)

Journal of Forensic Sciences, EarlyView.
Abstract In the medicolegal context, GSR analysis plays a key role in clarifying the dynamics of firearm‐related deaths, including lesion identification and firing distance determination. However, postmortem alterations of the body, such as thermal exposure, may influence the analysis of lesions and complicate interpretation.
