Variable Gain DNA Nanostructure Charge Amplifiers for Biosensing

December 7, 2024
Author(s)
Jacob Majikes, Seulki Cho, Thomas Cleveland, James Liddle, Arvind Balijepalli
Electronic measurements of engineered nanostructures comprised solely of DNA (DNA nanostructures) enable new signal conditioning modalities in biosensing. Here, we demonstrate how these DNA nanostructures alter their conformation upon binding a nucleic

Development and performance of a low-cost, solid-state, thermal neutron sensor with a 10B converter

December 5, 2024
Author(s)
Priscila Costa, Jamie Weaver, M Raele, Kevin Pritchard, Juscelino Leao, C Domienikan, Nicholas C. Maliszewskyj, F da Silva, W Pereira, Frederico Genezini
This study demonstrates the construction and operation of a portable, solid-state thermal neutron sensor that utilizes a photodiode coated with a thin layer of boron-10 (10B). The boron layer was created using pulsed laser deposition and analyzed through

Reliability in Building Blocks for Secure Software

December 5, 2024
Author(s)
Paul Black
In February 2024 the U.S. White House Office of the National Cyber Director (ONCD) released "Back to the Building Blocks: A Path Toward Secure and Measurable Software.'' The report makes the case that the technical community can greatly improve

Wound Causing Agents in the Illicit Drug Supply: Evidence from a Statewide Drug Checking Program

December 5, 2024
Author(s)
Emily Martin, Kristin Schneider, Edward Sisco, Meghan Appley, Margaret Rybak, Rae Elkasabany, Susan Sherman
Objectives To examine the prevalence of wound causing agents (xylazine, levamisole, medetomidine) in Maryland's illicit drug supply and co-occurrence with other substances. Methods Using data from Maryland's statewide drug checking program, Rapid Analysis

Atomistic Origins of Conductance Switching in an e-Cu0.9V2O5 Neuromorphic Single Crystal Oscillator

December 4, 2024
Author(s)
Cherno Jaye, Conan Weiland, Daniel Fischer, John Ponis, Nicholas Jerla, George Agbeworvi, Saul Perez-Beltran, Nitin Kumar, Kenna Ashen, Jialu Li, Edrick Wang, Michelle A. Smeaton, Fatme Jardali, Sarbajeet Chakraborty, Patrick J. Shamberger, Katherine L. Jungjohann, Lu Ma, Jinghua Guo, G Sambandamurthy, Xiaofeng Qian, Sarbajit Banerjee
: Building artificial neurons and synapses is key to achieving the promise of energy efficiency and acceleration envisioned for brain-inspired information processing. Emulating the spiking behavior of biological neurons in physical materials requires

Results of the 2023 Rapid DNA Multi-Laboratory Study - I-Chip

December 4, 2024
Author(s)
Erica Romsos, Lilliana Moreno, Douglas Hares
Identical sensitivity and mixture sample sets were provided to six external laboratories to evaluate the recent enhancements to the Rapid DNA technology for crime scene-type samples. Data were returned to the Federal Bureau of Investigation and the

Two tests of variance homogeneity for clustered data where group size is informative

December 3, 2024
Author(s)
Mary Gregg, Adam Creuziger, Somnath Datta, Douglas Lorenz
To evaluate variance homogeneity among groups for clustered data, Iachine et al. (Robust tests for the equality of variances for clustered data. J Stat Comput Simul 2010;80(4):365–377) introduced an extension of the well-known Levene test. However, this

Detecting Features of Antibody Structure Through Their Mediator-accessible Redox Activities

December 2, 2024
Author(s)
Dana Motabar, Eunkyoung Kim, Jinyang Li, Zhiling Zhao, Catherine Mouchahoir, David Travis Gallagher, John E. Schiel, Mamatha Garige, Carole Sourbier, Gregory F. Payne, William Bentley
Protein function relies on sequence, folding and post-translational modification and molecular measurements are commonly used to reveal these structural features. Here, we report an alternative approach that represents these molecular features as readily

Noiseless Loss Suppression for Entanglement Distribution

December 2, 2024
Author(s)
Cory Nunn, Daniel Jones, Todd Pittman, Brian Kirby
Recent work by Mičuda et al. [Phys. Rev. Lett 109, 180503 (2012)] suggests that pairing noiseless amplification with noiseless attenuation can conditionally suppress loss terms in the direct transmission of quantum states. Here we extend this work to

Optical Characterization of Parasitic Motion in a Long-Stroke Shaker

December 2, 2024
Author(s)
Jared Strait, Richard A. Allen
We present an optical scheme to simultaneously characterize the cross-axis and rotational parasitic motions of a long-stroke shaker. By leveraging the geometric properties of a corner cube retroreflector mounted on the shaker load table, we independently
