Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

open access: yesAdvanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Revised and Improved Procedure for Immunolocalization of Male Meiotic Chromosomal Proteins and Spindle in Plants without the Use of Enzymes

open access: yesPlants, 2018
Immunolocalization studies to visualize the distribution of proteins on meiotic chromosomes have become an integral part of studies on meiosis in the model organism Arabidopsis thaliana.

Introducing Synapsis

open access: yes, 2018
"Synapsis: A Health Humanities Journal" was founded in 2017 by Arden Hegele, a literary scholar, and Rishi Goyal, a physician. Its mission is to develop conversations among diverse people thinking about medical and humanistic ways of knowing . as a “Department Without Walls” that connects scholars and thinkers from different spheres.

Universal Neuromorphic Element: NbOx Memristor with Co‐Existing Volatile, Non‐Volatile, and Threshold Switching

open access: yesAdvanced Functional Materials, EarlyView.
A W/NbOx/Pt memristor demonstrates the coexistence of volatile, non‐volatile, and threshold switching characteristics. Volatile switching serves as a reservoir computing layer, providing dynamic short‐term processing. Non‐volatile switching, stabilized through ISPVA, improves reliable long‐term readout. Threshold switching operates as a leaky integrate

Genetic Interactions Between the Meiosis-Specific Cohesin Components, STAG3, REC8, and RAD21L

open access: yesG3: Genes, Genomes, Genetics, 2016
Cohesin is an essential structural component of chromosomes that ensures accurate chromosome segregation during mitosis and meiosis. Previous studies have shown that there are cohesin complexes specific to meiosis, required to mediate homologous ...

Synapsis of loxP Sites by Cre Recombinase [PDF]

open access: yesJournal of Biological Chemistry, 2007
Cre recombinase catalyzes site-specific recombination between 34-bp loxP sites in a variety of topological and cellular contexts. An obligatory step in the recombination reaction is the association, or synapsis, of Cre-bound loxP sites to form a tetrameric protein assembly that is competent for strand exchange.

Predicting Knot or Catenane Type of Site-Specific Recombination Products

open access: yes, 2007
Site-specific recombination on supercoiled circular DNA yields a variety of knotted or catenated products. We develop a model of this process, and give extensive experimental evidence that the assumptions of our model are reasonable. We then characterize

A Van der Waals Optoelectronic Synapse with Tunable Positive and Negative Post‐Synaptic Current for Highly Accurate Spiking Neural Networks

open access: yesAdvanced Functional Materials, EarlyView.
A van der Waals optoelectronic synaptic device based on a ReS2/WSe2 heterostructure and oxygen‐treated h‐BN is presented, which enables both positive and negative PSCs through photocarrier polarity reversal. Bidirectional plasticity arises from gate‐tunable band bending and charge trapping‐induced quasi‐doping.

The conserved ATPase PCH-2 controls the number and distribution of crossovers by antagonizing their formation in Caenorhabditis elegans

open access: yeseLife
Meiotic crossover recombination is essential for both accurate chromosome segregation and the generation of new haplotypes for natural selection to act upon. This requirement is known as crossover assurance and is one example of crossover control.
