On ω-Interpolative Berinde Weak Contraction in Quasi-Partial b-Metric Space
International Journal of Analysis and Applications, 2021 The aim of this paper is to introduce interpolative weak contraction in the notion of Berinde weak operator in quasi-partial b-metric space and to extend and generalize fixed point results by adopting the condition of ω-admissibility.

, 2003 The methods of quantum chemistry and solid state theory to solve the many-body problem are reviewed. We start with the definitions of reduced density matrices, their properties (contraction sum rules, spectral resolutions, cumulant expansion, $N ...

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

COMMON FIXED POINT IN 𝐺-METRIC SPACES VIA GENERALIZED Γ-𝐶_𝐹 -SIMULATION FUNCTION
Проблемы анализаWe present the generalized Γ-𝐶_𝐹 -simulation function and establish the common fixed point result for weak (𝜂_𝐹 , 𝑔) q-contraction in complete 𝐺-metric space. The exploration extends to its ramifications on both quasi-metric spaces and metric spaces. The

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Endpoints of φ-weak and generalized φ-weak contractive mappings
Filomat, 2012 Let (X, d) be a complete metric space, and let T:X ? Pd,bd (X) be a multi-valued ?-weak or generalized ?-weak contractive mapping. Then T has a unique endpoint if and only if T has the approximation endpoints property. Our results extend previous results given by Ciric(1974), Nadler (1969), Daffer-Kaneko (1995), Rhoades (2001), Rouhani and ...

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 ...

Molecular Oncology, EarlyView.Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Contraction Consistent Stochastic Choice Correspondence [PDF]
We model a general choice environment via probabilistic choice correspondences, with (possibly) incomplete domain and infinite universal set of alternatives. We offer a consistency restriction regarding choice when the feasible set contracts.

Fixed Point Results in Partial Symmetric Spaces with an Application
Axioms, 2019 In this paper, we first introduce the class of partial symmetric spaces and then prove some fixed point theorems in such spaces. We use one of the our main results to examine the existence and uniqueness of a solution for a system of Fredholm integral ...
