Genotypic variation of dormancy in wheat (Triticum aestivum L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science, Department of Plant Science, Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 1996
Embryo dormancy and α - amylase dormancy are desirable in wheat to minimise pre-harvest sprouting damage. The current work focuses on the embryo and graincoat colour.

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

open access: yesAdvanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Gradual approximation of the domain of attraction by gradual extension of the "embryo" of the transformed optimal Lyapunov function [PDF]

open access: yesarXiv, 2002
In this paper an autonomous analytical system of ordinary differential equations is considered. For an asymptotically stable steady state x0 of the system a gradual approximation of the domain of attraction DA is presented in the case when the matrix of the linearized system in x0 is diagonalizable.

Lineage-specific gene expression and the regulative capacities of the sea urchin embryo: a proposed mechanism [PDF]

open access: yes, 1989
Three aspects of early sea urchin development are reviewed, and conclusions derived that lead to a unified concept of how the initial specifications of differential gene activity may occur in this embryo. i.

The Embryo Sac and Embryo of Gnetum gnemon [PDF]

open access: yesBotanical Gazette, 1908
1. The "antipodal tissue" described by Lotsy as occurring in Gnetum Gnemon at the fertilization stage is a sharply differentiated nutritive tissue developed in the nucellus beneath the embryo sac, which at this stage contains only free nuclei, as described for other species of Gnetum. 2.

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

open access: yesAdvanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Embryo staging with weakly-supervised region selection and dynamically-decoded predictions [PDF]

open access: yesarXiv, 2019
To optimize clinical outcomes, fertility clinics must strategically select which embryos to transfer. Common selection heuristics are formulas expressed in terms of the durations required to reach various developmental milestones, quantities historically annotated manually by experienced embryologists based on time-lapse EmbryoScope videos.

A Critical Examination of the Question of Personhood in Stem Cell Research [PDF]

open access: yes, 2016
Stem cell research programme has been celebrated world over as the most promising medical research in the 21st century. However, the method of stem cell research involves the use and unavoidable destruction of human embryo.

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

open access: yesAdvanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Optimization of Buffalo (Bubalus bubalis) Embryonic Stem Cell Culture System

open access: yesCell Journal, 2015
Objective: In order to retain an undifferentiated pluripotent state, embryonic stem (ES) cells have to be cultured on feeder cell layers. However, use of feeder layers limits stem cell research, since experimental data may result from a combined ES ...
