Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions

open access: yesAdvanced Intelligent Systems, EarlyView.
Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Physiology and Robustness of Yeasts Exposed to Dynamic pH and Glucose Environments

open access: yesBiotechnology and Bioengineering, EarlyView.
The authors investigated how three Saccharomyces cerevisiae strains respond to dynamic substrate and pH oscillations using dynamic microfluidic single‐cell cultivation (dMSCC) and intracellular biosensors. By combining performance and robustness analysis of selected intracellular parameters, growth and morphological analysis, the authors identified ...

Morphological Features-Based Descriptive Index System for Lunar Impact Craters

open access: yesISPRS International Journal of Geo-Information, 2017
Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence ...

Projectile Interactions in Granular Impact Cratering

open access: yesPhysical Review Letters, 2008
We present evidence for the interactions between a ball and the container boundaries, as well as between two balls, that are mediated by the granular medium during impact cratering. The presence of the bottom boundary affects the final penetration depth only for low drop heights with shallow filling, in which case, surprisingly, the penetration becomes

Molecular parameters of post impact cooling in the Boltysh impact structure [PDF]

open access: yes, 2010
Impact events have the potential to generate a number of long-term sources of heat that can lead to the initiation of hydrothermal systems when the impact occurs on a water- or ice-rich target.

New Trends in SERS Substrates With Micro‐ and Nanostructures: Materials, Substrates, Preparation, and Applications

open access: yesBattery Energy, EarlyView.
In this review, the latest research progress in surface‐enhanced Raman scattering (SERS) is discussed comprehensively. It covers four main aspects of SERS technology: materials utilized, various types of SERS substrates, methods employed for their preparation, and recent applications explored in the field over the past few years.

Low-speed impact craters in loose granular media [PDF]

open access: yes, 2003
We report on craters formed by balls dropped into dry, non-cohesive, granular media. By explicit variation of ball density $\rho_{b}$, diameter $D_{b}$, and drop height $H$, the crater diameter is confirmed to scale as the 1/4 power of the energy of the ...

Penetration depth for shallow impact cratering

open access: yesPhysical Review E, 2005
We present data for the penetration of a variety of spheres, dropped from rest, into a level non-cohesive granular medium. We improve upon our earlier work [Uehara {\it et al.} Phys. Rev. Lett. {\bf 90}, 194301 (2003)] in three regards. First, we explore the behavior vs sphere diameter and density more systematically, by holding one of these parameters

A Second Large Subglacial Impact Crater in Northwest Greenland? [PDF]

open access: yes
Following the discovery of the Hiawatha impact crater beneath the northwest margin of the Greenland Ice Sheet, we explored satellite and aerogeophysical data in search of additional such craters.
