Topological quantum materials represent a new class of matter with both exotic physical phenomena and novel application potentials. Many Heusler compounds, which exhibit rich emergent properties such as unusual magnetism, superconductivity and heavy fermion behaviour, have been predicted to host non-trivial topological electronic structures. The coexistence of topological order and other unusua...

introduction: ingestion of a foreign body is a common problem among all age groups. most of the foreign bodies in the pharynx are usually lodged at the level of cricopharynx. the diagnosis is based on history, clinical, and radiological examination. most foreign-body ingestions are accidental, but there may be contributory factors such as mental disorder, alcoholism, and prison incarceration. t...

ed from: Nguyen Xuan Nguyen et al. (January 2010). Study on adoption of the System of Rice Intensification in Northern provinces of Vietnam. A report by commissioned by Oxfam America. On average, each woman from an SRI Farmer Field School promotes 5-8 other farmers to adopt SRI while the rate is only 1-3 for male graduates. Top: FFS graduates in Dông Trù village, Hanoi province, undertake SRI t...

In this work some complex behaviors of a controlled reverse flow reactor is presented. The control system introduces discrete events making the model an infinite dimensional hybrid system. The study is conducted through continuation techniques and brute force numerical simulations. Together with standard bifurcations like pitchfork, saddle-node and Neimark–Sacker, varying the set-point paramete...

Interchanging the left and right eye views of a scene (pseudoscopic viewing) has been reported to produce vivid stereoscopic effects under certain conditions. In two separate field studies, we examined the experiences of 124 observers (76 in Study 1 and 48 in Study 2) while pseudoscopically viewing a distant natural outdoor scene. We found large individual differences in both the nature and the...

For hundreds of years, scientists have been studying light, which is used nowadays to explore the universe and cure diseases. Here, we present the results of a survey indicating a significant support from a subset of the academic community to investigate rare, unusual and unexplained atmospheric light phenomena that have historically been unexplored by scientists—the transient luminous phenomen...

At very small scales, thermodynamic energy exchanges like work and heat become comparable to the thermal of system, which leads unusual phenomena transient violations second law. We explore generic characters such systems using framework stochastic thermodynamics provide a preliminary overview basic concepts. Here, we have attempted put into simple terms some actively pursued topics arrow time,...

Chiral active matter comprises particles which can self-propel and self-rotate. Examples range from sperm cells bacteria near walls to asymmetric colloids pea-shaped Quincke rollers. In this perspective article we focus on recent developments in chiral matter. After briefly discussing motion at a single particle level, discuss collective phenomena ranging vortex arrays patterns made of rotating...

Uspanteko is an endangered Mayan language spoken by up to 6000 people in the Guatemalan highlands. We provide overview of phonetics and phonology Uspanteko, focussing on phenomena which are common languages and/or typologically interesting. These include glottalised consonants (ejectives, implosives, glottal stop), uvular consonants, vowel length contrasts, syllable structure, stress, lexical t...
