Covariant techniques for computation of the heat kernel [PDF]

open access: yes, 1997
The heat kernel associated with an elliptic second-order partial differential operator of Laplace type acting on smooth sections of a vector bundle over a Riemannian manifold, is studied.

Response of Maize Crop to Spatial Arrangement and Staggered Interseeding of Haricot Bean

open access: yesInternational Journal of Environment, 2014
Field studies conducted to determine the effects of intercrop row arrangements and staggered intercropping of haricot bean (Phaseolus vulgaris L.) on the performances of maize (Zea mays L.) crop at Hallaba and Taba areas in 2013 cropping season, southern

Study of the low intensity spectral bands within the infrared spectra of kernels of high-yielding maize hybrids [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2019
The nature, role, and significance of low intensity spectral bands con­tained within the infrared spectra of kernels of high-yielding maize hybrids: ZP 341, ZP 434, and ZP 505 were observed in this study.

Genetic dissection of QTLs for starch content in four maize DH populations

open access: yesFrontiers in Plant Science, 2022
Starch is the principal carbohydrate source in maize kernels. Understanding the genetic basis of starch content (SC) benefits greatly in improving maize yield and optimizing end-use quality.

Kernel‐based clustering

open access: yesElectronics Letters, 2013
Proposed is a novel clustering technique based on kernel methods. The geometric properties of normalised kernel spaces are exploited to automatically detect the correct number of clusters, thus avoiding the requirement of an initial estimate of this parameter, as required instead in many popular algorithms.

Singular integral operators, a brief historical overview of its evolution

open access: yesSelecciones Matemáticas, 2022
In this work we give an analytical-historical view of the classical theory of singular integrals introduced by A.P. Calderón-A. Zygmund. Emphasis is given to their applications to PDEs and to some projections of the theory.

Kernel Interpolation for Scalable Structured Gaussian Processes (KISS-GP) [PDF]

open access: yes, 2015
We introduce a new structured kernel interpolation (SKI) framework, which generalises and unifies inducing point methods for scalable Gaussian processes (GPs).

Systemic T Cell Receptor Profiling Reveals Adaptive Immune Activation and Potential Immune Signatures of Diagnosis and Brain Atrophy in Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Epilepsy is increasingly associated with immune dysregulation and inflammation. The T cell receptor (TCR), a key mediator of adaptive immunity, shows repertoire alterations in various immune‐mediated diseases. The unique TCR sequence serves as a molecular barcode for T cells, and clonal expansion accompanied by reduced overall TCR ...

Operators for transforming kernels into quasi-local kernels that improve SVM accuracy [PDF]

open access: yes, 2008
Motivated by the crucial role that locality plays in various learning approaches, we present, in the framework of kernel machines for classification, a novel family of operators on kernels able to integrate local information into any kernel obtaining ...
