Challenges in Setting up a Manufacturing Plant during Pandemic

September 5, 2021
Author(s)
kiwook jung, Scott Nieman, Boonserm Kulvatunyou
Pandemic of 2019 brought on many challenges. Sustaining manufacturing production is one of them. Some market segments may experience reductions in demands, while other market segments may experience explosions. Companies have to deal with these changing

Understanding molt control switches: Transcriptomic and expression analysis of the genes involved in ecdysteroidogenesis and cholesterol uptake pathways in the Y-organ of the blue crab, Callinectes sapidus

September 3, 2021
Author(s)
Tracey Johnston, Elena Legrand, J. Sook Chung, Tsvetan Bachvaroff
The crustacean molting process is regulated by an interplay of hormones produced by the eyestalk ganglia and Y-organs (YO). Molt-inhibiting hormone and crustacean hyperglycemic hormone released by the sinus gland of the eyestalk ganglia (EG) inhibit the

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

Kristina Kvashnina, Yoshiyuki Amemiya, Dibyendu Bhattacharyya, Ingolf Lindau, Andrew J. Allen
This is an Editorial for the Journal of Synchrotron Radiation (JSR) to inform all readers, authors and supporters about the coming transition of the journal to become fully open access. All papers submitted to JSR after 1 October 2021, will be for open

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
