Certification of Standard Reference Materials(R) 2969 and 2970: Vitamin D Metabolites in Frozen Human Serum (Total 25-Hydroxyvitamin D Low Level) and (25-Hydroxyvitamin D2 High Level)

September 2, 2021
Author(s)
Grace Hahm, Michael Nelson, Johanna Camara, Blaza Toman
Standard Reference Materials (SRMs) 2969 and 2970 are intended for 1) use in validating methods for determining concentrations of 25-hydroxyvitamin D2 (25(OH)D2) and 25-hydroxyvitamin D3 (25(OH)D3) in human serum and plasma and 2) value assigning in house

Basic Recommendations For HVAC Cybersecurity

September 1, 2021
Author(s)
Michael Galler
Cybersecurity has been a topic of increasing importance for several years. While fully securing a large system can be very complicated, there are some basic precautions that can easily be applied to any system. The purpose of this document is to briefly

Evaluation of existing infiltration models used in building energy simulation

September 1, 2021
Author(s)
Yeonjin Bae, Jaewan Joe, Seungjae Lee, Piljae Im, Lisa Ng
Infiltration modeling is one of the major sources of uncertainty in building energy simulation. Although many infiltration models exist, their structures and assumptions vary, and many of them are inaccurate for commercial buildings. The use of these

Magnetic proximity effect in magnetic-insulator/heavy-metal heterostructures across the compensation temperature

September 1, 2021
Author(s)
Jackson Bauer, Patrick Quarterman, Alexander Grutter, Bharat Khurana, Subhajit Kundu, K. Mkhoyan, Julie A. Borchers, Caroline Ross
The magnetic proximity effect in Pt and W thin films grown on Dy3Fe5O12 (DyIG) is examined at temperatures above and below the magnetic compensation temperature of the ferrimagnetic insulator. Polarized neutron reflectometry indicates that the proximity

Nanopore sensing: a physical-chemical approach

September 1, 2021
Author(s)
Joseph W. Robertson, Madhav Ghimire, Joseph Reiner
Protein nanopores have emerged as an important class of sensor, for the understanding of biophysical processes, such as molecular transport across membranes, and detection and characterization of biopolymers. We trace the development of these sensors from

Neural Networks Based Domain Name Generation

September 1, 2021
Author(s)
Zheng Wang, Yang Guo
Domain generation algorithm (DGA) is commonly used to dynamically produce a large number of random domain names and select a small subset for actual use. DGA provides a method to make DNS mapping elusive and thereby make countermeasures ineffective. Modern
