Research on cooperative control strategy for high efficiency and energy saving in virtually coupled train sets based on two-layer optimization

open access: yes机车电传动
Virtual coupling is one of the cutting-edge technologies under research in the field of rail transportation. In order to improve operational efficiency and reduce operational energy consumption for virtually coupled train sets, this paper proposes a ...

Representations for optimal stopping under dynamic monetary utility functionals [PDF]

open access: yes
In this paper we consider the optimal stopping problem for general dynamic monetary utility functionals. Sufficient conditions for the Bellman principle and the existence of optimal stopping times are provided.

Phase transitions and noise sensitivity on the Poisson space via stopping sets and decision trees [PDF]

open access: yes, 2021
Proofs of sharp phase transition and noise sensitivity in percolation have been significantly simplified by the use of randomized algorithms, via the OSSS inequality (proved by O’Donnell, Saks, Schramm and Servedio in [59]) and the Schramm-Steif ...

The C‐terminal region of KIF26B is indispensable for nephron progenitor condensation and kidney formation in mice

open access: yesFEBS Open Bio, EarlyView.
KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

On stopping rules for the SETS schemes: an application of the success runs theory [PDF]

open access: yes, 1994
A stopping rule is proposed for the SETS scheme (Chen, 1978). The method of generating functions and partial fractions are applied to the theory of the success runs.

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

open access: yesFEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

An Approach to Stopping Problems of a Dynamic Fuzzy System [PDF]

open access: yes, 2000
We formulate a stopping problem for dynamic fuzzy systems concerning with fuzzy decision environment. It could be regarded as a natural fuzzification of non-fuzzy stopping problem with a deterministic dynamic system.

Versatile vector tools for efficient protein screening across multiple expression systems

open access: yesFEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Stations routières en Gaule romaine : architecture, équipements et fonctions

open access: yesGallia, 2016
This collection aims to expand the literature on relay stations in Roman Gaul. The subject, which is of interest to both political and economic history, warrants a new perspective in the light of recent archaeological data emerging for the period from ...

Non-cooperative n-person game with a stopped set

open access: yesJournal of Mathematical Analysis and Applications, 1982
AbstractA continuous time non-cooperative n-person Markov game with a stopped set is studied in this paper. We prove that, in the game process with or without discount factor, there exists an optimal stationary point of strategies, called the equilibrium point, and each player has his equilibrium stationary strategy, such that the total expected ...
