Cryo-transmission electron microscopy (cryo-EM) of frozen hydrated specimens is an efficient method for the structural analysis of purified biological molecules. However, cryo-EM and cryo-electron tomography are limited by the low signal-to-noise ratio (SNR) of recorded images, making detection of smaller particles challenging. [...]

Background: Depressive symptoms are rising in the general population, but their associated factors are unclear. Although the link between sleep disturbances and depressive symptoms severity (DSS) is reported, the predictive role of sleep on DSS and the impact of anxiety and the brain on their relationship remained obscure.Methods: Using three population-based datasets (N = 1813), we trained the machine learning models in the primary dataset (N = 1101) to assess the predictive role of sleep quality, anxiety problems, and brain structural (and functional) measurements on DSS, then we tested our models' performance in two independent datasets (N = 378, N = 334) to test the generalizability of our findings.

Gas separation membranes can play a huge role in the future as a separation technology for hydrogen due to its poten-tial application as an environmentally friendly energy storage- or as a propulsion system for vehicles. Natural gasstreams are considered as a means of transportation for hydrogen as long as a suitable technology can be used toseparate hydrogen from the rest of the gas at the end of the process. [...]

Collisions provided by a TeV-scale beam at the LHC on a fixed target will explore a unique kinematic region that has been poorly probed until now. Furthermore, advanced detectors make available probes that have never been accessed before.The LHCb spectrometer possesses the unique capability to function as a fixed-target experiment by injecting gas into the LHC beampipe while proton or ion beams are circulating.

The integration of volatile, renewable energies into building and district energy systems requires novel algorithms that are capable of controlling the augmented complexity and the interactions of subsystems efficiently. Local energy communities will consist of a multitude of different small and large scale components using a variety of communication protocols. [...]

The fast and user-friendly generation of controller models is a crucial prerequisite for the widespread implementation and scalability of Model Predictive Control (MPC) for buildings. Apart from this, these models can be employed for evaluating other more and more relevant characteristics of buildings, for example, energy-saving potentials in user behavior or the building’s flexibility potential to reduce or shift loads.
