Rock avalanches move large volumes of material causing a highly destructive power over large areas. In these events, it is possible to monitor the evolution of slopes but failure cannot be always prevented. For this reas...

Germanium-on-silicon (Ge-on-Si) single photon avalanche diodes (SPADs) have received wide attention in recent years due to their potential to be integrated with Si photonics. In this work, we propose and demonstrate a hi...

While silicon single-photon avalanche diodes (SPAD) have reached very high detection efficiency and timing resolution, their use in fibre-optic communications, optical free space communications, and infrared se...

Abstract Powder snow avalanches (PSAs) radiate infrasound energy, yet the source mechanism remains unclear, limiting hazard monitoring and mitigation with infrasound‐based technologies. Here, we analyze a unique data s...

This paper reviews the genesis of a chaotic deposit in the Blanco River basin (BRB) in the Argentine Andes that has been interpreted to be either of debris flow or glacial origin. A detailed sedimentological and geomorph...

Abstract A transistor avalanche noise generator (TANG) is described. It is based on an off-the-shelf RF transistor with an integrated planar monopole. From a 70 V DC power it generates sub-nanosecond pulses with amplitud...

Rapid flow-like landslides, particularly debris flows and debris avalanches, cause significant economic damage and many victims worldwide every year. They are usually extremely fast with the capability of travelling long...

We consider the directed percolation process as a prototype of systems displaying a nonequilibrium phase transition into an absorbing state. The model is in a critical state when the activation probability is adjusted at...

Avalanche lifetime distributions have been related to first-return random walk processes. In this sense, the theory for random walks can be employed to understand, for instance, the origin of power law distributions in s...

The specific aspects of designing germanium avalanche and non-avalanche threshold photodiodes for use in optical radiation testers of fiber-optic communication systems are discussed. It is shown that the application of e...

The possibility of a type-IIb diamond as the foundation for double-drift region (DDR) impact avalanche transit time (IMPATT) devices that operate at THz frequencies has been investigated. In this study, the large-signal ...

Los domos riolíticos representan fases efusivas dentro de la evolución de estructuras volcánicas poligenéticas o erupciones que construyen edificios volcánicos monogenéticos espacialmente aislados o formando parte ...

Abstract Snow transport (wind drifting and avalanches) can concentrate a large amount of water into a relatively small area, in contrast to precipitation, which is spatially smoother. I develop a framework to constrain t...

We analyze the behavior of different elastoplastic models approaching the yielding transition. We propose two kinds of rules for the local yielding events: Yielding occurs above the local threshold either at a constant r...

The paper defines philosophical categories of good and evil in the process of upbringing and development of the personality. People are good by nature. That is why they tend towards the good, they desire what is good, th...

The appearance of Hou Hsiao-hsien’s 侯孝賢 film The Assassin in 2015 and its distinction the same year with the Best Director’s award at the film festival in Cannes has launched an avalanche of confused and confus...

The characteristic angles of the granular media depend on such grain parameters as size, geometry and roughness, as well as the degree of packing fraction or compactivity, and the relative humidity within the medium. In ...

Currently, laser-induced structural modifications in optical materials have been an active field of research. In this paper, we reported structural modifications in the bulk of sapphire due to picosecond (ps) laser filam...

At certain voltages, using an analogy with gaseous discharges, aqueous-based conduction cells enter a conduction phase that can be described as an avalanche, in which the current rises unbounded, which is limited by the ...

Las conclusiones sobre los deslizamientos individualizados en la cordillera neuquina (36°-38°S), (su inducción sísmica; rechazo de la consideración de sus depósitos como till),indujo a proyectar su estudio al sur d...

This paper presents a metasurface-based light receiver tailored for compact off-axis light detection and ranging (LiDAR) systems, addressing the critical challenge of simultaneously enhancing the field of view (FOV) and ...

Em meados dos anos 1980, alguns autores, entre eles Arthur Danto, defenderam ideias que convergiam para a proclamação do fim da arte. Esse período histórico coincidia com a explosão dos estilos pós-modernos nas art...

The SARS-CoV-2 coronavirus pandemic has forced changes in many areas of human life activity, also in the field of science, educating students and popularization knowledge. These changes were avalanche-like. Sudden increa...
