let a be a banach algebra and e be a banach a-bimodule then s = a  e, the l1-direct sum of a and e becomes a module extension banach algebra when equipped with the algebras product (a; x):(a′; x′) = (aa′; a:x′ + x:a′). in this paper, we investigate △-amenability for these banach algebras and we show that for discrete inverse semigroup s with the set of idempotents es, the module extension bana...

abtract Purpose Drugs targeting the programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) pathway show significant clinical activity across several tumor types. However, a majority of patients do not respond to these agents. Use of biomarker assays to predict response to these agents is an active area of research; however, the predictive value of PD-L1 immunohistochemistry (IHC)...

this empirical study reports on a cross-linguistic analysis of the overarching issue of l1 lexicalization regarding two (non)-interventionist approaches to vocabulary teaching. participants were seventy four juniors at the islamic azad university, roudehen branch in tehran. the investigation pursued (i) the impact of the provided (non)-interventionist treatments on both sets of (non)-lexicalize...

Abstract: The present study examined whether Cantonese-English bilingual listeners made use of their L1 probabilistic phonotactics in the segmentation process of English continuous speech (L2). Previous research in different languages demonstrated that probabilistic phonotactics could serve as a useful cue to locate the possible word boundary in continuous speech. The use of these kinds of info...

Programmed death ligand 1 (PD-L1) has emerged as a biomarker that can help to predict responses to immunotherapies targeted against PD-L1 and its receptor (PD-1). Companion tests for evaluating PD-L1 expression as a biomarker of response have been developed for many cancer immunotherapy agents. These assays use a variety of detection platforms at different levels (protein, mRNA), employ diverse...

PD-L1 is an immunoinhibitory molecule that suppresses the activation of T cells, leading to the progression of tumors. Overexpression of PD-L1 in cancers such as gastric cancer, hepatocellular carcinoma, renal cell carcinoma, esophageal cancer, pancreatic cancer, ovarian cancer, and bladder cancer is associated with poor clinical outcomes. In contrast, PD-L1 expression correlates with better cl...
