An intrinsic order-theoretic characterization of the weak expectation property [PDF]
, 2017 We prove the following characterization of the weak expectation property for operator systems in terms of Wittstock's matricial Riesz separation property: an operator system $S$ satisfies the weak expectation property if and only if $M_{q}(S)$ satisfies ...

WEAK DIMENSION AND CHAIN-WEAK DIMENSION OF ORDERED SETS
Bulletin of the Korean Mathematical Society, 2005 The notions of the ``weak dimension'' \(\text{wdim}(P)\) and the ``chain-weak dimension'' \(\text{cwdim}(P)\) of a (finite) poset \(P\) are introduced. The chain-weak dimension is the smallest \(n\) such that \(P\) can be embedded in a product of \(n\) chain-weak orders, a chain-weak order being a poset \(P = C_1 \cup \cdots \cup C_m\), where each ...

Weak order in averaging principle for stochastic differential equations with jumps
Advances in Difference Equations, 2018 In this paper, we deal with the averaging principle for a two-time-scale system of jump-diffusion stochastic differential equations. Under suitable conditions, we expand the weak error in powers of timescale parameter.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Strengthening weak measurements of qubit out-of-time-order correlators [PDF]
, 2018 For systems of controllable qubits, we provide a method for experimentally obtaining a useful class of multitime correlators using sequential generalized measurements of arbitrary strength.

The Weak Order on Pattern-Avoiding Permutations [PDF]
The Electronic Journal of Combinatorics, 2014 The weak order on the symmetric group is a well-known partial order which is also a lattice. We consider subposets of the weak order consisting of permutations avoiding a single pattern, characterizing the patterns for which the subposet is a lattice. These patterns have only a single small ascent or descent.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Weak solutions of degenerated quasilinear elliptic equations of higher order
International Journal of Mathematics and Mathematical Sciences, 1996 We prove the existence of weak solutions of higher order degenerated quasilinear elliptic equations. The main tools are the degree theory for generalized monotone mappings and imbedding theorems between weighted Sobolev spaces.

Local Convergence of an Optimal Eighth Order Method under Weak Conditions
Algorithms, 2015 We study the local convergence of an eighth order Newton-like method to approximate a locally-unique solution of a nonlinear equation. Earlier studies, such as Chen et al. (2015) show convergence under hypotheses on the seventh derivative or even higher,
