A Simulation Study for Optimal Pinhole Collimator Design in Gamma Camera Systems
Journal of Medical PhysicsBackground: The usage of a semiconductor detector with a pinhole collimator can provide high spatial resolution due to its high intrinsic resolution. However, the collimator system has low sensitivity due to the hole’s small diameter.

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Random walk, excess smoothness or excess sensitivity? Evidence from literature and an application for Turkish economy [PDF]
This paper observes the Turkish household’ consumption data to see whether it follows random walk or not. The quarterly data covers the period from 1987:1 to 2003:4.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Cluster sample inference using sensitivity analysis: the case with few groups [PDF]
This paper re-examines inference for cluster samples. Sensitivity analysis is proposed as a new method to perform inference when the number of groups is small.

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

A Sensitivity-Based Algorithm Approach in Reconstructing Images in Electrical Impedance Tomography
IEEE AccessElectrical impedance tomography (EIT) is a medical imaging technique used to reconstruct images inside the domain of interest. EIT collects data on the boundary of the domain to infer the conductivity distribution inside the domain.

Genetics of Environmental Sensitivity and its Moderating Effects on Mental Health Outcomes [PDF]
, 2019 PhDAccording to differential susceptibility theories, individuals vary in the extent to which they are impacted by the quality of their environment, with some individuals identified as generally more sensitive than others making them more susceptible to ...
