Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

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 ...

Model-informed oracle training for enhancing active learning without external knowledge

Machine Learning with Applications
In real-world applications of active learning frameworks, human oracles are often imperfect, and label noise is introduced into the learning process.

One-loop structure of parton distribution for the gluon condensate and “zero modes”

Journal of High Energy Physics, 2021
We present results for one-loop corrections to the recently introduced “gluon condensate” PDF F(x). In particular, we give expression for the gg-part of its evolution kernel.

X structures in B+ → J/ψ ϕ K+ as one-loop and double-triangle threshold cusps

Physics Letters B, 2022
The LHCb data on B+→J/ψϕK+ show four peaks and three dips in the J/ψϕ invariant mass distribution, and the peaks are interpreted as X(4140), X(4274), X(4500) and X(4685)/X(4700) resonance contributions.

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.

Architecture of a network-in-the-Loop environment for characterizing AC power system behavior [PDF]

, 2010
This paper describes the method by which a large hardware-in-the-loop environment has been realized for three-phase ac power systems. The environment allows an entire laboratory power-network topology (generators, loads, controls, protection devices, and

The three-loop splitting functions Pqg(2) and Pgg(2,NF)

Nuclear Physics B, 2017
We calculate the unpolarized twist-2 three-loop splitting functions Pqg(2)(x) and Pgg(2,NF)(x) and the associated anomalous dimensions using massive three-loop operator matrix elements. While we calculate Pgg(2,NF)(x) directly, Pqg(2)(x) is computed from

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
