Survey of Leafminers on American Chestnut and other Castanea spp. (Fagales: Fagaceae) on Long Island, NY.

The effect of the 20th-century functional extinction of the American Chestnut (Fagaceae: Castanea dentata (Marshall) Borkh) on associated herbivorous insects is unknown. These insects include leafminers that spend at least part of their larval phase feeding between the epidermises of leaves. We surveyed leafminers on C.

Multi-site integrated optical addressing of trapped ions.

One of the most effective ways to advance the performance of quantum computers and quantum sensors is to increase the number of qubits or quantum resources in the system. A major technical challenge that must be solved to realize this goal for trapped-ion systems is scaling the delivery of optical signals to many individual ions. In this paper we demonstrate an approach employing waveguides and multi-mode interferometer splitters to optically address multiple Yb ions in a surface trap by delivering all wavelengths required for full qubit control.

TIR domain-associated nucleotides with functions in plant immunity and beyond.

TIR (Toll/interlukin-1 receptor) domains are found in archaea, bacteria and eukaryotes, featured in proteins generally associated with immune functions. In plants, they are found in a large group of NLRs (nucleotide-binding leucine-rich repeat receptors), NLR-like proteins and TIR-only proteins. They are also present in effector proteins from phytopathogenic bacteria that are associated with suppression of host immunity.

SARM1-Dependent Axon Degeneration: Nucleotide Signaling, Neurodegenerative Disorders, Toxicity, and Therapeutic Opportunities.

Axons are an essential component of the nervous system, and axon degeneration is an early feature of many neurodegenerative disorders. The NAD metabolome plays an essential role in regulating axonal integrity. Axonal levels of NAD and its precursor NMN are controlled in large part by the NAD synthesizing survival factor NMNAT2 and the pro-neurodegenerative NADase SARM1, whose activation triggers axon destruction.

A compact cold-atom interferometer with a high data-rate grating magneto-optical trap and a photonic-integrated-circuit-compatible laser system.

The extreme miniaturization of a cold-atom interferometer accelerometer requires the development of novel technologies and architectures for the interferometer subsystems. Here, we describe several component technologies and a laser system architecture to enable a path to such miniaturization. We developed a custom, compact titanium vacuum package containing a microfabricated grating chip for a tetrahedral grating magneto-optical trap (GMOT) using a single cooling beam.
