Signatures of topology in ballistic bulk transport of HgTe quantum wells

We calculate bulk transport properties of two-dimensional topological insulators based on HgTe quantum wells in the ballistic regime. Interestingly, we find that the conductance and the shot noise are distinctively different for the so-called normal regime (the topologically trivial case) and the so-called inverted regime (the topologically non-trivial case). Thus, it is possible to verify the topological order of a two-dimensional topological insulator not only via observable edge properties but also via observable bulk properties. This is important because we show that under certain conditions the bulk contribution can dominate the edge contribution which makes it essential to fully understand the former for the interpretation of future experiments in clean samples.Comment: 5 pages, 4 figure

Integrated Cooperation in Implementing Firearm Deactivation Capabilities: Bosnia and Herzegovina

Many of the illegal firearms used for terrorist and criminal activities throughout Europe originate from the Balkan region and have previously been legally exported and sold as deactivated firearms. However, due to variations in the quality of deactivation standards and verification processes, many deactivated firearms can easily be reactivated into fully functional military weapons. To prevent the illegal reactivation of additional weapons, new guidelines regarding deactivation standards and techniques have been introduced, thus ensuring that deactivated firearms are rendered irreversibly inoperable. Within the framework of the European Union Force Bosnia and Herzegovina (EUFOR), a training program regarding the deactivation of firearms has been developed and implemented by the Armed Forces of Bosnia and Herzegovina (AFBiH)

When a Safety Measure Becomes a Risk Accelerant: Removing the Option to Blast-in-Place When Clearing Explosive Remnants of War

The legacy of unexploded ordnance (UXO) and abandoned ammunition following armed conflict will, in many cases, have a severe impact on society and daily life, even for years or decades after hostilities end. These explosive remnants of war (ERW) represent a grave threat in many aspects, and the human, societal, and environmental impact can be severe. These explosive objects must therefore be located and disposed of—a job in itself that involves serious risks. Therefore, various safety measures are implemented to mitigate these risks. Some safety measures, however, could prove to have less than the desired effect, and in the worst cases, could even increase the risk

Fraunhofer pattern in the presence of Majorana zero modes

Majorana bound states (MBSs) emerge as zero energy excitations in topological superconductors. At zero temperature, their presence gives a quantized conductance in NS junctions and a fractional Josephson effect in Josephson junctions when the parity is conserved. However, most of current experiments deviate from the theoretical predictions, yielding for example a non-quantized conductance or the absence of only few odd Shapiro steps. Although these results might be compatible with a topological ground state, it is also possible that a trivial scenario can mimic similar results, by means of accidental zero energy Andreev bound states (ZEABS) or simply by non-adiabatic transitions between trivial Andreev bound states. Here, we propose a new platform to investigate signatures of the presence of MBSs in the Fraunhofer pattern of Josephson junctions featuring quantum spin Hall edge states on the normal part and Majorana bound states at the NS interfaces. We use a tight-binding model to demonstrate a change in periodicity of the Fraunhofer pattern when comparing trivial and non-trivial regimes. We explain these results in terms of local and crossed Andreev bound states, which due to the spin-momentum locking, accumulate different magnetic flux and therefore become distinguishable in the Fraunhofer periodicity. Furthermore, we introduce a scattering model that captures the main results of the microscopic calculations with MBSs and extend our discussion to the main differences found using accidental ZEABS.Comment: 17 pages, 14 figures.

Identification of the Content of Biologically Active Substances in Nut Shots

One of ways of the food industry development is a search for non-traditional raw material resources with the high content of physiologically healthy nutrients. A promising way of biologically important raw materials is secondary products of oil production, especially shots. The aim of the research was to determine the content of biologically active substances in nut shots (cedar nut shot (CNS) and walnut shot (WNS)). The quality composition of the phenol nature was established by reactions with 10 % alcohol solutions of FeCl3, NaOH, АlCl3 and cyanidin test. The content of hydroxycinnamic acids (with recalculation for chlorogenic acid) was determined by the spectrophotometric method. The amount of tanning substances – by the method of permanganometry. The analysis of the sum of flavonoids (in recalculation for rutin) was realized by the method of differential spectrophotometry. Carbonic acids were identified by the method of gas-liquid chromatography. There were revealed quality differences in the composition of substances of the phenol nature for CNS and WNS. WNS is characterized by the higher content of hydroxycinnamic acids – in 2,5 times, tanning substances – in 3,1 times and flavonoids – in 60 times, comparing with CNS. The content of unsaturated fats in WNS is 95,79 % of the total number of fats, and in CNS – 80,05 %. The ratio Omega-3/Omega-6 for the fat component of CNS is 1/0,06, and for WNS fats – 1/1,3. WNS comparing with CNS is characterized by the higher content of Malic (in 5,3 times) and fumaric (in 100 times)acid. CNS contains more lemon (in 2,9 times) and succinic (in 2,2 times) acid. That is, identification of the content of some biologically active substances in nut shots allows to recommend them for usage in technologies of food products. It allows to enrich them with phenol compounds, polyunsaturated fats and organic acids
