Parallelism in random access machines [PDF]
Proceedings of the tenth annual ACM symposium on Theory of computing - STOC '78, 1978 A model of computation based on random access machines operating in parallel and sharing a common memory is presented. The computational power of this model is related to that of traditional models. In particular, deterministic parallel RAM's can accept in polynomial time exactly the sets accepted by polynomial tape bounded Turing machines ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Purely antiferromagnetic magnetoelectric random access memory
Nature Communications, 2017 Magnetoelectric coupling allows switching of magnetic states via gate voltage pulses. Here the authors propose and demonstrate a purely antiferromagnetic magnetoelectric random access memory based on Cr2O3, reporting 50-fold reduction of writing ...

Channel-Aware Multichannel Random Access for Energy-Limited Sensors and MTC Devices
IEEE Access, 2018 In machine-type communications (MTC) or wireless sensor networks (WSNs), since MTC devices or sensors have limited supply of energy, energy efficient transmission schemes are important.

Is random access memory random? [PDF]
Most software is contructed on the assumption that the programs and data are stored in random access memory (RAM). Physical limitations on the relative speeds of processor and memory elements lead to a variety of memory organizations that match processor
