A Modified Rough Set Approach to Incomplete Information Systems [PDF]

Journal of Applied Mathematics and Decision Sciences, 2007
The key point of the tolerance relation or similarity relation presented in the literature is to assign a “null” value to all missing attribute values. In other words, a “null” value may be equal to any value in the domain of the attribute values.

Information Entropy and Information Granulation-based Uncertainty Measures in Incomplete Information Systems [PDF]

, 2014
: In this paper, concepts of information entropy and information granulation-based uncertainty measures are introduced in incomplete information/decision systems, and based on maximal consistent block technique, some variants of information entropy and ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Probabilistic Approximation under Incomplete Information Systems [PDF]

, 2007
By applying the probability estimation of the unavailable attributes derived from the available attributes to the neighborhood system, the suited degree of each neighbor to a given object is depicted. Therefore, the neighborhood space with guaranteed suited precision is obtained. We show how to shrink the rule search space via VPRS model for this space,

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Comparing the Comparative Efficiency of System Marginal Price and Pay as Bid Auctions in Electricity Markets [PDF]

Pizhūhishnāmah-i Iqtiṣād-i Inirzhī-i Īrān, 2014
System marginal price auction and pay as bid auction are common auctions in electricity markets. The present article discusses the impacts of selecting between different common auctions in electricity markets (system marginal price auction and pay as bid

Graph-theoretic algorithms for cyber-physical vulnerability analysis of power grid with incomplete information

Journal of Modern Power Systems and Clean Energy, 2018
A key focus recently has been in assessing the risk of a coordinated cyber-physical attack and minimizing the impact of a successful attack. Most of the cyber-attackers will have limited system information and conventional power grid N − 1 security ...

Switching from Complete to Incomplete Information

, 2007
We construct an elementary mechanism [dutta, b., sen, a., vohra, r., 1995. Nash implementation through elementary mechanisms in economic environments. Review of economic design 1, 173–203] that nash implements the constrained walrasian correspondence. We

Controlling the stochastic sensitivity in thermochemical systems under incomplete information [PDF]

, 2018
summary:Complex dynamic regimes connected with the noise-induced mixed-mode oscillations in the thermochemical model of flow reactor are studied. It is revealed that the underlying reason of such excitability is in the high stochastic sensitivity of the ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...
