On Some n-C2 and Strongly C2 Extensions

Algebra Colloquium, 2020
Let R be a ring and n be a positive integer. Then R is called a left n-C2-ring (strongly left C2-ring) if every n-generated (finitely generated) proper right ideal of R has nonzero left annihilator. We discuss some n-C2 and strongly C2 extensions, such as trivial extensions, formal triangular matrix rings, group rings and [Formula: see text][D, C].

Abelian groups with C2

Journal of Algebra and Its Applications, 2023
Almost all Abelian groups with the property that each subgroup isomorphic to a direct summand, is also a direct summand, are determined. The relationship with co-Hopfian groups is also addressed.

Highly Efficient Electroreduction of CO2 to C2+ Alcohols on Heterogeneous Dual Active Sites.

Angewandte Chemie, 2020
Electroreduction of CO2 to liquid fuels such as ethanol and n-propanol, powered by renewable electricity, offers a promising strategy for controlling the global carbon balance and addressing the need for the storage of intermittent renewable energy.

The reinforcement of a C2 laminar screw by a C2 laminar hook as an anchor of occipito-C2 fusion

European Journal of Orthopaedic Surgery & Traumatology, 2013
Although a C1-C2 transarticular screw (TAS) or a C2 pedicle screw (PS) is the most rigid anchor for C2, each entails the risk of vertebral artery injury. Although a C2 laminar screw (LS) is often used as an alternative anchor in such cases, its anchoring strength may be inadequate.

C2S

2015
Skyline queries may be used to filter interesting data from a broad range of data. A Skyline query selects those data that are the best according to multiple user-defined criteria. A special case of Skyline queries are the Spatial Skyline Queries (SSQ).

Oxygen-Functionalized Ultrathin Ti3 C2 Tx MXene for Enhanced Electrocatalytic Hydrogen Evolution.

ChemSusChem, 2019
Two-dimensional (2D) transition-metal carbides (MXenes) are widely adopted as potential electrocatalysts for the hydrogen evolution reaction (HER) owing to their metallic conductivity, rich tunable surface chemistry, and atomic thickness with highly ...

Decrypting C2 inhibitors

Blood, 2014
In this issue of Blood, Nguyen et al employ high-resolution mapping to precisely define epitopes on the C2 domain of blood coagulation factor VIII (FVIII).1 Their results nicely complement a recent report in Blood describing the structure of a ternary complex of 2 inhibitory antibodies with the C2 domain.2 Together, these studies reveal fascinating ...

Properties of Mycobacteriophage C2

Experientia, 1969
Le mycobacteriophage C2 a une morphologie typique tete-queue, la longueur de la tete etant de 60 nm et celle de la queue de 200 nm. Le genome du phage est un acide desoxyribonucleique. Le phage C2 joue un role important dans la genetique mycobacterienne.
