We explore Bott Vanishing for elliptic surfaces over $${\mathbb {P}}^1$$ . show that is significantly affected by the geometric properties of fibers. For example, whether there exist certain types singular fibers on fibration such as cuspidal an ample line bundle surface with large self-intersection, these give criteria Vanishing.

Two new species, Ooencyrtus alrake Hayat, sp. nov. and Syrphophagus wayanadensis Hayat, sp. nov. (Hymenoptera: Chalcidoidea: Encyrtidae), are described from material collected in Kerala State (India) from Trioza jambolanae Crawford (Hemiptera: Psylloidea: Triozidae), a leaf gall-inducer on species of Syzygium (Myrtaceae). Two species, Psyllaephagus garuga S. Singh and P. phacopteron S. Singh, b...

A fundamental problem in machine learning is identifying the most representative subset of features from which we can construct a predictive model for a classification task. This paper aims to present a validation study of dimensionality reduction effect on the classification accuracy of mammographic images. The studied dimensionality reduction methods were: locality-preserving projection (LPP)...

Abstract For every positive integer r , we introduce two new cohomologies, that call E r {E_{r}} -Bott–Chern and -Aeppli, on compact complex manifolds. When = 1 {r\kern-1.0pt=\kern-1.0pt1} they coincide with the usual Bott–Chern Aeppli but are...

Abstract We provide families of compact astheno-Kähler nilmanifolds and we study the behaviour complex blowup such manifolds. prove that existence an metric satisfying extra differential condition is not preserved by blowup. also interplay between Strong Kähler with torsion metrics geometrically Bott–Chern metrics. show Fino–Parton–Salamon are geometrically-Bott–Chern-formal, whereas obtain neg...

The zero-forcing (ZF) and minimum mean square error (MMSE) based detectors can approach optimal performance in the uplink of massive multiple-input multiple-output (MIMO) systems. However, they require inverting a matrix whose complexity is cubic relation to dimension. This lead high computational effort, especially MIMO To mitigate this, several iterative methods have been proposed literature....
