Existence of convex and non convex local solutions for fractional differential inclusions

Electronic Journal of Differential Equations, 2009
In this paper, we establish the existence theorems for a class of fractional differential inclusion of order $n-1 < alpha leq n $. The study holds in two cases, when the set-valued function has convex and non-convex values.

RETRACTED ARTICLE: Extremal surface with the light-like line in Minkowski space R1+(1+1) $R^{1+(1+1)}$

Boundary Value Problems, 2017
In this paper, firstly we will give the global construction of the mixed type extremal surface in Minkowski space along the analytic light-like line. Furthermore, we construct simply the local existence of extremal surface along a single light-like line.

On Pair Creation of Extremal Black Holes and Kaluza-Klein Monopoles

, 1993
Classical solutions describing charged dilaton black holes accelerating in a background magnetic field have recently been found. They include the Ernst metric of the Einstein-Maxwell theory as a special case.

RaMBat: Accurate identification of medulloblastoma subtypes from diverse data sources with severe batch effects

Molecular Oncology, EarlyView.
To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.

Existence and comparison results for quasilinear evolution hemivariational inequalities

Electronic Journal of Differential Equations, 2004
We generalize the sub-supersolution method known for weak solutions of single and multivalued nonlinear parabolic problems to quasilinear evolution hemivariational inequalities.

Electrovacuum Near-horizon Geometries in Four and Five Dimensions

, 2011
Associated to every stationary extremal black hole is a unique near-horizon geometry, itself a solution of the field equations. These latter spacetimes are more tractable to analyze and most importantly, retain properties of the original black hole which

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Generalised Harrison transformations and black diholes in Einstein-ModMax

Journal of High Energy Physics
Einstein-Maxwell theory has powerful solution generating techniques which include Harrison transformations in the Ernst formalism. We construct generalised Harrison transformations that preserve the purely magnetic or purely electric sector in Einstein ...

Exact Solutions and the Attractor Mechanism in Non-BPS Black Holes

, 2007
The attractor mechanism for the four-dimensional ${\cal N}=2$ supergravity black hole solution is analyzed in the case of the D0-D4 system. Our analyses are based on newly derived exact solutions, which exhibit explicitly the attractor mechanism for ...
