LatticeMech: A discrete mechanics code to compute the effective static properties of 2D metamaterial structures

SoftwareX, 2020
In the current work, we provide a Bernoulli beam-mechanics based code for the computation of the effective static properties of two-dimensional, metamaterial lattice structures.

Maple procedures for the coupling of angular momenta. VI. LS-jj transformations

, 2004
Transformation matrices between different coupling schemes are required, if a reliable classification of the level structure is to be obtained for open-shell atoms and ions.

Pathogen-host reorganization during Chlamydia invasion revealed by cryo-electron tomography [PDF]

, 2014
Invasion of host cells is a key early event during bacterial infection, but the underlying pathogen-host interactions are yet to be fully visualised in three-dimensional detail.

Drug export pathway of multidrug exporter AcrB revealed by DARPin inhibitors.

PLoS Biology, 2007
The multidrug exporter AcrB is the inner membrane component of the AcrAB-TolC drug efflux system in Escherichia coli and is responsible for the resistance of this organism to a wide range of drugs.

Magnetospheric considerations for solar system ice state [PDF]

, 2018
The current lattice configuration of the water ice on the surfaces of the inner satellites of Jupiter and Saturn is likely shaped by many factors. But laboratory experiments have found that energetic proton irradiation can cause a transition in the ...

Decoupling Hybrid Metal Walls and Half-Wavelength Diagonal Open-Slots Based Four-Port Square Patch Antenna With High Port Isolation and Low Radiation Correlation for 2.4/5/6 GHz WiFi-6E 4 × 4 MIMO Access Points

IEEE Access, 2022
Based on applying the hybrid metal walls and half-wavelength diagonal open-slots, a four-port square patch antenna (SPA) having high port isolation (>20 dB) and low radiation correlation (envelope correlation coefficients < 0.01) for 2.4/5 ...

WIKIBrainStem: An online atlas to manually segment the human brainstem at the mesoscopic scale from ultrahigh field MRI

NeuroImage, 2021
The brainstem is one of the most densely packed areas of the central nervous system in terms of gray, but also white, matter structures and, therefore, is a highly functional hub.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
