Imaging the wakes of jets with energy-energy-energy correlators

Journal of High Energy Physics
Abstract As the partons in a high energy jet propagate through the droplet of quark-gluon plasma (QGP) produced in a heavy-ion collision they lose energy to, kick, and are kicked by the medium. The resulting modifications to the parton shower encode information about the microscopic nature of QGP.

Serial amplification of tau filaments using Alzheimer's brain homogenates and C322A or C322S recombinant tau

FEBS Letters, EarlyView.
We investigated the seeded assembly of 0N3R tau and two variants, C322A and C322S, designed to model the mutation landscape at residue 322, using Alzheimer's disease brain homogenates in a real‐time quaking‐induced conversion (RT‐QuIC) assay. The C322A variant formed filaments that partially resembled the paired helical filament (PHF) structure ...

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

FEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

Dark Energy or just Energy?

, 2019
This research note hypothesizes new physics without dark energy, dark matter, extra dimensions, or deviation from proven mathematical models. The main assumption is that matter expands proportionally with space, and that the proposed discrete step-expansion of the elementary particles may provide a platform for unification of the four fundamental ...

Energy and strategic energy planning

, 2023
Since the renewable energy transition fundamentally alters how energy is generated, transported, and utilized, it also redefines the role that energy has in space and how space can or should be planned. A changing energy-space nexus as a result of the energy transition therefore calls on planners involved in the production, distribution, and ...

ACSS2 involved in acetyl‐CoA synthesis regulates skeletal muscle function

FEBS Letters, EarlyView.
The enzyme acyl‐coenzyme A synthetase short‐chain family member‐2 (ACSS2) catalyzes the conversion of acetate to acetyl‐CoA, but its function in skeletal muscle is unclear. We studied ACSS2 deficiency in mouse and fly models. Skeletal muscle from the mouse model showed atrophic fibers, excess lipid, and depleted NADH.

A working model for cytoplasmic assembly of H/ACA snoRNPs

FEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Energie

, 2016
Énergie le terme « énergie » provient du grec energon et signifie étymologiquement « force en action ». c'est « l'apport nécessaire à un système matériel pour lui faire subir une transformation » (mérenne-Schoumaker, 2011, p. 15). de sa production à sa consommation, l'énergie marque et façonne profondément les territoires. il existe plusieurs sources d'

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

FEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation
