UV Sensitivity of Indium-Zinc Oxide Nanofibers

open access: yesAdvances in Materials Science and Engineering, 2018
Indium-zinc oxide (IZO) nanofiber matrices are synthesized on SiO2-covered silicon substrates by the electrospinning method. The nanofibers’ dimensions, morphology, and crystalline structure are characterized by scanning electron microscopy, atomic force

A simple model of mixing and chemical reaction in a turbulent shear layer [PDF]

open access: yes, 1981
Arguments are presented to show that the concept of gradient diffusion is inapplicable to mixing in turbulent shear layers. A new model is proposed for treating molecular mixing and chemical reaction in such flows at high Reynolds number.

Electrical Switching in Thin Film Structures Based on Transition Metal Oxides

open access: yesAdvances in Condensed Matter Physics, 2015
Electrical switching, manifesting itself in the nonlinear current-voltage characteristics with S- and N-type NDR (negative differential resistance), is inherent in a variety of materials, in particular, transition metal oxides.

Method of increasing the information capacity of associative memory of oscillator neural networks using high-order synchronization effect

open access: yes, 2018
Computational modelling of two- and three-oscillator schemes with thermally coupled $VO_2$-switches is used to demonstrate a novel method of pattern storage and recognition in an impulse oscillator neural network (ONN) based on the high-order ...

Abrupt metal-insulator transition observed in VO2 thin films induced by a switching voltage pulse

open access: yes, 2005
An abrupt metal-insulator transition (MIT) was observed in VO2 thin films during the application of a switching voltage pulse to two-terminal devices.

Bishop Torhthelm’s letter to Boniface

open access: yesEarly Medieval Europe, Volume 33, Issue 2, Page 244-273, May 2025.
In c.738, St Boniface distributed a circular letter to a broad audience of ecclesiastics in England. One response to that letter survives, written by Torhthelm, bishop of the Middle Angles (737–64). The letter is written in an allusive style and borrows heavily from its main source, Pope Vitalian’s letter to Oswiu, king of Northumbria.

Developmental Processes and Stages in the Acquisition of Cardinality [PDF]

open access: yes, 1990
This is a study of the level of children's understanding of cardinality, focusing on the difference between a true cardinality response and the application of a mechanically learned rule.

Primary care clinicians’ perspectives about quality measurements in safety-net clinics and non-safety-net clinics

open access: yesInternational Journal for Equity in Health, 2018
Background Quality metrics, pay for performance (P4P), and value-based payments are prominent aspects of the current and future American healthcare system. However, linking clinic payment to clinic quality measures may financially disadvantage safety-net

A Model of an Oscillatory Neural Network with Multilevel Neurons for Pattern Recognition and Computing

open access: yes, 2019
The current study uses a novel method of multilevel neurons and high order synchronization effects described by a family of special metrics, for pattern recognition in an oscillatory neural network (ONN). The output oscillator (neuron) of the network has

Linking the key physiological functions of essential micronutrients to their deficiency symptoms in plants

open access: yesNew Phytologist, Volume 242, Issue 3, Page 881-902, May 2024.
Summary In this review, we untangle the physiological key functions of the essential micronutrients and link them to the deficiency responses in plants. Knowledge of these responses at the mechanistic level, and the resulting deficiency symptoms, have improved over the last decade and it appears timely to review recent insights for each of them.
