Heliospheric modulation of the interstellar dust flow on to Earth

open access: yes, 2018
Aims. Based on measurements by the Ulysses spacecraft and high-resolution modelling of the motion of interstellar dust (ISD) through the heliosphere we predict the ISD flow in the inner planetary system and on to the Earth.

Wavelike patterns in precessing elliptical rings for swarming systems [PDF]

open access: yes, 2017
A continuum model for a swarm of devices is investigated with the devices moving along precessing elliptical Earth-centered orbits. Wavelike patterns in these precessing elliptical rings with peaks in swarm density are found that can be used to provide ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

open access: yesMolecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

A Comprehensive Review of Open Caisson Modeling Technology: Current Practices and Future Prospects

open access: yesApplied Sciences
The rapid advancement of modern megapolises has led to a dearth of surface space, and, in response, engineers have begun to trial substitutes below ground level.

Revisiting Mission‐Oriented Cancer Research to tackle the increasing burden of cancer in Europe–a policy perspective

open access: yesMolecular Oncology, EarlyView.
Translational cancer research and its implementation through competitively selected Comprehensive Cancer Centers across Europe should be the primary policy focus for addressing the increasing cancer burden in Europe and counteract the present main strategy to convert cancer to a chronic disease.

Asymmetrical deformation characteristics and mechanisms of deep excavations induced by one-side unloading

open access: yesYantu gongcheng xuebao
With the advancement of urban renewal, more and more excavations are being constructed under one-side unloading condition caused by the existing adjacent ones, resulting in different deformation characteristics and mechanisms compared to those of the ...

Carbonation of Chrysotile under Subduction Conditions

open access: yesEngineering, 2019
In order to understand the role of serpentine minerals in the global carbon cycle, high-pressure X-ray diffraction (XRD) experiments were performed on chrysotile (Mg3Si2O5(OH)4) using carbon dioxide (CO2) as a pressure medium.

Lifshitz Transitions in 122-Pnictides Under Pressure

open access: yes, 2014
We demonstrate, using $T=0$ first principles total energy calculations, that observed pressure-driven anomalies in the entire 122-pnictides family ($A$Fe$_2$As$_2$; $A$ = alkali earth element Ca, Sr, Ba) can be understood as consequences of Lifshitz ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Pressure calibrations of high-pressure large-volume presses at HPSTAR [PDF]

open access: yesMatter and Radiation at Extremes
Large-volume presses (LVPs) are widely utilized in diverse research fields—including high-pressure physics, chemistry, materials science, and Earth and planetary sciences—to investigate the physical and chemical properties of materials under extreme high-
