Signatures of the Martian rotation parameters in the Doppler and range observables

open access: yes, 2017
The position of a Martian lander is affected by different aspects of Mars' rotational motions: the nutations, the precession, the length-of-day variations and the polar motion.

A new smooth failure criterion for concrete inspired by Lubliner's condition

open access: yesStructural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Tectonic interpretation of large scale geodetic measurements (VLBI, SLR) in the Central Mediterranean region: constraints and uncertainties

open access: yesAnnals of Geophysics, 1995
Some considerations are reported on the tectonic setting and microplate mosaic in the Mediterranean zones where VLBI and SLR stations are located. In particular, the possible sources of ambiguity in the determination of the Africa-Eurasia and Adriatic ...

Landscape factors influencing predation on capercaillie nests by two competing mesopredators: pine marten and red fox

open access: yesWildlife Biology, EarlyView.
Predation by pine martens Martes martes and red foxes Vulpes vulpes is an important factor influencing the population dynamics of capercaillie Tetrao urogallus. However, there is a knowledge gap regarding the relative effects of these mesopredators on the reproductive success of capercaillie. To better understand how various landscape factors influence

Assessing Ground Displacement in Oran City, Algeria: A Comparative Analysis of PSInSAR, SBAS, and Combined Method

open access: yesGeodetski Vestnik
Coastal cities are grappling with ground deformation, making monitoring the temporal evolution of ground subsidence crucial. Advanced interferometric techniques, such as PSInSAR and SBAS provide a pertinent mean to observe this phenomenon by supplying ...

The interdisciplinary role of space geodesy—Revisited [PDF]

open access: yesJournal of Geodynamics, 2010
Abstract In 1988 the interdisciplinary role of space geodesy has been discussed by a prominent group of leaders in the fields of geodesy and geophysics at an international workshop in Erice (Mueller and Zerbini, 1989). The workshop may be viewed as the starting point of a new era of geodesy as a discipline of Earth sciences.

APPLICATIONS OF SPACE GEODESY METHODS IN ROMANIA

open access: yesSWS Journal of EARTH and PLANETARY SCIENCES, 2020
The studies for Recent Crustal Movements by the aid of space geodesy techniques are integrated into the researches on the Earth’s crust dynamics, as a reflection of the complex geodynamic phenomena that occur in the crust and in the subcrustal lithosphere.

Bayesian perspective for orientation determination in cryo‐EM with application to structural heterogeneity analysis

open access: yesActa Crystallographica Section D, EarlyView.
A Bayesian perspective on orientation estimation in cryo‐EM is presented, with the minimum mean‐square error estimator outperforming standard cross‐correlation‐based approaches, particularly under challenging low signal‐to‐noise conditions. We demonstrate that improved orientation estimation has a decisive impact on 3D reconstruction quality and ...

Hurricane‐induced risk contagion in commercial real estate: Evidence from Hurricane Sandy

open access: yesReal Estate Economics, EarlyView.
Abstract This study examines how hurricane‐induced destruction affects the prices of nearby undamaged commercial real estate properties, using Hurricane Sandy as a natural experiment. Using Real Capital Analytics transaction records spatially merged with Federal Emergency Management Agency building‐level damage data, we empirically employ a difference ...
