The effect of burnable absorbers on criticality and reactivity coefficient of VVER-1000 assembly [PDF]
Nuclear Technology and Radiation ProtectionBurnable absorbers play an important role in nuclear reactor safety and exploring their effect on the reactor core behavior is an important issue in the design and operation of the reactor core.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Modelling the outer radiation belt as a complex system in a self-organised critical state [PDF]
, 2005 The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of measured outer electron radiation belt data are well ...

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.

Blackouts, risk, and fat-tailed distributions [PDF]
We analyze a 19-year time series of North American electric power transmission system blackouts. Contrary to previously reported results we find a fatter than exponential decay in the distribution of inter- occurrence times and evidence of seasonal ...

Mixed-Criticality Systems with Partial Lockdown and Cache Reclamation Upon Mode Change [PDF]
, 2017 29th Euromicro Conference on Real-Time Systems (ECRTS 2017), WiP. Dubrovnik, Croatia.In mixed-criticality multicore systems, the appropriate degree of isolation between applications of different criticalities is a primary objective.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

A Memory Arbitration Scheme for Mixed-Criticality Multicore Platforms
, 2014 In mixed-criticality systems, applications of different crit- icality levels share the same computing platform. To avoid spatial and temporal interference of the applications, the computing platform must implement measures for spatial and temporal ...

Modelling the tuned criticality in stick-slip friction during metal cutting [PDF]
, 2015 Cutting is a ubiquitous process in nature and man-made systems. Here we demonstrate that, based on morphological patterns observed in experiments, the friction behaviour of metal cutting exhibits a criticality with cutting speed as a tuned parameter. The
