Genetics of powdery mildew disease resistance in blackgram [Vigna mungo (L.) Hepper]

open access: yesElectronic Journal of Plant Breeding, 2023
Powdery mildew susceptible (VBN 11) and resistant (LBG 17) blackgram genotypes were crossed. Parents, F1, F2, F3, F4 and BC1F2 of cross VBN 11 X LBG 17 were screened against powdery mildew disease.

A Joint Method Based on Time-Frequency Distribution to Detect Time-Varying Interferences for GNSS Receivers with a Single Antenna

open access: yesSensors, 2019
In this paper, a joint method combining Hough transform and reassigned smoothed pseudo Wigner-Ville distribution (RSPWVD) is presented to detect time-varying interferences with crossed frequency for a Global Navigation Satellite System (GNSS) receiver ...

Crosstalk Reduction in Square Cavities

open access: yesIEEE Photonics Journal, 2009
Theoretically and experimentally, we demonstrate that low crosstalk between two crossed line-defect waveguides formed in a square lattice photonic crystal (PC) structure can be achieved using a resonant cavity at the intersection area.

Light Like a Feather: A Fibrous Natural Composite with a Shape Changing from Round to Square

open access: yesAdvancement of science, 2016
Only seldom are square/rectangular shapes found in nature. One notable exception is the bird feather rachis, which raises the question: why is the proximal base round but the distal end square?

Integrable and proper actions on C*-algebras, and square-integrable representations of groups [PDF]

open access: yes, 1998
We propose a definition of what should be meant by a proper action of a locally compact group on a C *-algebra. We show that when the C *-algebra is commutative this definition exactly captures the usual notion of a proper action on a locally compact ...

On non-negative estimation of variance components in mixed linear models

open access: yesJournal of Advanced Research, 2016
Alternative estimators have been derived for estimating the variance components according to Iterative Almost Unbiased Estimation (IAUE). As a result two modified IAUEs are introduced.

Crossed Andreev reflection in diffusive contacts: Quasiclassical Keldysh-Usadel formalism [PDF]

open access: yes, 2006
Crossed Andreev reflection in multiterminal structures in the diffusive regime is addressed within the quasiclassical Keldysh-Usadel formalism. The elastic cotunneling and crossed Andreev reflection of quasiparticles give nonlocal currents and voltages ...

Referral Patterns and Diagnostic Timeliness in Pediatric Cancer: A Hospital‐Based Study in Indonesia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely diagnosis and treatment are critical for improving survival among children with cancer. In low‐ and middle‐income countries (LMICs), delays are common and may be influenced by fragmented referral pathways and diagnostic limitations.
