Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Influence of Boron Diffusion on Photovoltaic Parameters of n+-p-p+ Silicone Structures and Based Photodetectors

East European Journal of Physics
The paper investigates the photovoltaic properties of the silicon n+-p-p+-structures and photodiodes made on their basis. It was found that boron diffusion to the reverse side of the substrate, in addition to creating an ohmic contact, generates ...

Compensation for Process and Temperature Dependency in a CMOS Image Sensor

Sensors, 2019
This paper analyzes and compensates for process and temperature dependency among a (Complementary Metal Oxide Semiconductor) CMOS image sensor (CIS) array. Both the analysis and compensation are supported with experimental results on the CIS’s dark

Multimodal shifts in the dark current of silicon photomultipliers

Journal of Instrumentation
Abstract The dark count rate is one of the key properties of avalanche photodiodes (APDs) and silicon photomultipliers (SiPMs). Previous studies have reported discrete shifts in the dark count rate on short timescales (∼10 ms to ∼100 s) with small increases (up to ∼1 kHz per APD).

Current and Future Searches for Dark Matter [PDF]

AIP Conference Proceedings, 2006
Recent experimental data confirms that approximately one quarter of the universe consists of cold dark matter. Particle theories provide natural candidates for this dark matter in the form of either Axions or Weakly Interacting Massive Particles (WIMPs). A growing body of experiments is aimed at direct or indirect detection of particle dark matter.

Double-Disk Dark Matter [PDF]

, 2013
Based on observational tests of large scale structure and constraints on halo structure, dark matter is generally taken to be cold and essentially collisionless.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Charge-Domain Type 2.2 µm BSI Global Shutter Pixel with Dual-Depth DTI Produced by Thick-Film Epitaxial Process

Sensors
We developed a 2.2 µm backside-illuminated (BSI) global shutter (GS) pixel featuring true charge-domain-correlated double sampling (CDS). To enhance the inverse parasitic light sensitivity (1/PLS), we implemented a thick-film epitaxial process ...

Dark current mechanisms in bulk GaInNAs photodiodes [PDF]

, 2008
We have grown a series of bulk GaInNAs p-i-n diodes and identified some of the dark current mechanisms present in our devices. With a nitrogen composition of ~4 %, the band gap can be reduced to 0.94 eV.
