MicroRNA 3′-compensatory pairing occurs through two binding modes, with affinity shaped by nucleotide identity and position

open access: yeseLife, 2022
MicroRNAs (miRNAs), in association with Argonaute (AGO) proteins, direct repression by pairing to sites within mRNAs. Compared to pairing preferences of the miRNA seed region (nucleotides 2–8), preferences of the miRNA 3′ region are poorly understood ...

Pairing Phase Transitions of Matter under Rotation. [PDF]

open access: yesPhysical Review Letters, 2016
The phases and properties of matter under global rotation have attracted much interest recently. In this Letter we investigate the pairing phenomena in a system of fermions under the presence of rotation.

Dynamic Encrypted Data Sharing Scheme Based on Conditional Proxy Broadcast Re-Encryption for Cloud Storage

open access: yesIEEE Access, 2017
Since Cloud Service Provider is a semi-trusted party in cloud storage, to protect data from being disclosed, users' data are encrypted before being uploaded to a cloud server.

On Pauli pairs [PDF]

open access: yesJournal of Mathematical Physics, 2013
The state of a system in classical mechanics can be uniquely reconstructed if we know the positions and the momenta of all its parts. In 1958 Pauli has conjectured that the same holds for quantum mechanical systems. The conjecture turned out to be wrong.

Reproductive aspects of Hyalella carstica (Amphipoda: Hyalellidae) in a natural environment in southeastern Brazil

open access: yesNauplius
The reproductive aspects of populations are important determinants of their ability to maintain themselves throughout time. In the case of amphipods from the genus Hyalella Smith, 1874, the reproductive period is easily determined by the presence of ...

BCS-BEC Crossover Effects and Pseudogap in Neutron Matter

open access: yesUniverse, 2020
Due to the large neutron–neutron scattering length, dilute neutron matter resembles the unitary Fermi gas, which lies half-way in the crossover from the BCS phase of weakly coupled Cooper pairs to the Bose–Einstein condensate of dimers.

Cohomologies of 3-Lie algebras with derivations [PDF]

open access: yesarXiv, 2021
In this paper, we consider a 3-Lie algebra with a derivation (called a 3-LieDer pair). We define cohomology for a 3-LieDer pair with coefficients in a representation. We use this cohomology to study deformations and abelian extensions of 3-LieDer pairs.

Cotorsion pairs induced by duality pairs

open access: yesJournal of Commutative Algebra, 2009
We introduce the notion of a duality pair and demonstrate how the left half of such a pair is often covering and preenveloping. As an application, we generalize a result by Enochs et al. on Auslander and Bass classes, and we prove that the class of Gorenstein injective modules introduced by Enochs and Jenda is covering when the ground ring has a ...

Mixing and Matching Chromosomes during Female Meiosis

open access: yesCells, 2020
Meiosis is a key event in the manufacturing of an oocyte. During this process, the oocyte creates a set of unique chromosomes by recombining paternal and maternal copies of homologous chromosomes, and by eliminating one set of chromosomes to become ...
