Stacking Lake Ice Analog Cryotectonic Dynamics on Dione’s Wispy Terrain
Physical Sciences Forum, 2023 Wispy Terrain, with its chasmata, is one of the enigmatic regions of Dione. It consists of quasi-parallel graben, and troughs, in parts with horsts, indicating extensional and shear stresses. This study introduces some observations of compression-related

Earth Surface Processes and Landforms, Volume 48, Issue 1, Page 198-214, January 2023., 2023 The Atlantic coast of NW Spain, where shingle beaches appear today, has suffered an important mobilization of dunes from a sea level about −120 m (bpsl), 20 ky ago. This aeolization caused the collapse of coastal/fluvial ecosystems (as forests) until the Late Holocene.

Zeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022 Abstract Large black single crystals with a metallic luster of Li16Sr6Ge6N and several other representatives of the series Li16Ae6Tt6N and Li16Ae6Tt6.5 (Ae=Ca, Sr; Tt=Si, Ge, Sn, Pb) were grown from mixtures of the respective elements with addition of binary alkaline‐earth metal nitrides or lithium nitride in the case of the nitrides. For the synthesis

Measurement methods and mathematical model of main characteristics of waveguide-coaxial connectors [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2021 Modern complex microwave radio electronic systems may use functional devices implemented on different types of transmission lines. In order to connect such devices to each other to form antenna feed system, the following three types of special connectors

Principles of implementing coaxial microwave connectors for modern radioelectronic systems [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2020 Many modern radioelectronic systems are based on antenna arrays such as APAA (active phased array antenna) or DAAR (digital active array antenna), which require specialized connectors of new types and design solutions for the input/output of the ...

Particular aspects of designing longitudinal-coaxial waveguide-microstrip connectors [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2022 The authors justify the use of combined longitudinal-coaxial connectors - waveguide-coaxial or waveguide-microstrip type - in new modern antenna-feeder microwave paths.

Centaur 2013 VZ70: Debris from Saturn's irregular moon population? [PDF]
A&A 657, A59 (2022), 2021 Context. Saturn has an excess of irregular moons. This is thought to be the result of past collisional events. Debris produced during such episodes in the neighborhood of a host planet can evolve into co-orbitals trapped in quasi-satellite and/or horseshoe resonant states.

The past and future obliquity of Saturn as Titan migrates [PDF]
A&A 647, A92 (2021), 2021 Aims: It has recently been shown that the fast migration of Titan could be responsible for the current 26.7{\deg}-tilt of Saturn's spin axis. We aim to quantify the level of generality of this result and to measure the most likely sets of parameters. We also aim to determine the obliquity that Saturn will reach in the future.
