Real-time traffic management and control have become necessary in today's networks due to their complexity and cybersecurity risks. With the increase in internet use, threats are more present and require real-time detection and analysis to prevent

Evaluation of upper age limits for HPV vaccination of US men for prevention of oropharyngeal cancers: A microsimulation-based modeling study

January 19, 2023
Author(s)
Rebecca Landy, Gregory Haber, Barry Graubard, Nicole Campos, Stephen Sy, Jane Kim, Emily Burger, Li Cheung, Hormuzd Katki, Maura Gillison, Anil Chaturvedi
Importance: HPV-positive oropharyngeal cancer is the most common HPV-associated cancer in the United States. Although permissible, the benefit of vaccination of US men aged 27-45 is uncertain because the natural history of HPV-induced oropharyngeal

Methods for the SI Value Assignment of the Purity of Organic Compounds (IUPAC Technical Report)

David Duewer, Katrice Lippa, Brian Lang, Blaza Toman, Michael Nelson, Kenneth W. Pratt, Steven Westwood, Yoshitaka Yoshitaka Shimuzu, Takeshi Saito, Beatrice Lalerle, Xinhua Dai, Stephen Davies, Marina Ricci, Annarita Baldan, Stefan Sarge, Haifeng Wang, Ralf D. Josephs, Michal Mariassy, Dietmar Pfieffer, John Warren, Wolfram Bremser, Stephen L.R. Ellison, Ting Huang, Ales Fajgelj, Lindsey Mackay, Robert Wielgosz
Metrological traceability to the SI of the result of an analysis for an organic compound is achieved through a calibration hierarchy anchored in a primary calibrator of the compound, the mass fraction content of which is established in a manner traceable

High-performance Kerr microresonator optical parametric oscillator on a silicon chip

January 16, 2023
Author(s)
Edgar Perez, Gregory Moille, Xiyuan Lu, Jordan Stone, Feng Zhou, Kartik Srinivasan
Optical parametric oscillation (OPO) is distinguished by its wavelength access, that is, the ability to flexibly generate coherent laser light at wavelengths that are dramatically different from the pump laser, and in principle bounded solely by energy

IEEE 802.11bf DMG Sensing: Enabling High-Resolution mmWave Wi-Fi Sensing

January 16, 2023
Author(s)
Steve Blandino, Tanguy Ropitault, Anirudha Sahoo, Nada T. Golmie
IEEE 802.11bf amendment is defining the Wireless Local Area Network (WLAN) sensing procedure, which supports sensing in license-exempt frequency bands below 7 GHz and above 40GHz. In this paper, we examine WLAN sensing in the millimeter wave band, i.e.,

Facile Polymerization in a Bicellar Template to Produce Polymer Nano-Rings

January 15, 2023
Author(s)
Chung-Hao Liu, Catherine Cheu, John Barker, Lin Yang, Mu-Ping Nieh
Hypothesis: A well-defined discoidal bicelle composed of three lipids, specifically zwitterionic long-chain 1,2-dipalmitoyl phosphocholine (DPPC) and short-chain 1,2-dihexanoyl phosphocholine (DHPC) doped with anionic 1,2-dipalmitoyl phosphoglycerol (DPPG)

Entering New Era of Thermoelectric Oxide Ceramics with High Power Factor through Designing Grain Boundaries

January 12, 2023
Author(s)
Cesar-Octavio Romo-De-La-Cruz, Yun Chen, Liang Liang, Sergio Paredes-Navia, Winnie Wong-Ng, Mark Williams, Xueyan Song
Thermoelectric (TE) oxide ceramics could play a significant role in waste heat recovery using TE generators, accelerating clean energy generation and achieving net-zero emissions. In 2003, the TE performance of single-crystal Ca3Co4O9+δ was evaluated with

X-ray absorption fine structure characterization of a multicomponent spinel catalyst

January 12, 2023
Author(s)
Evan Jahrman, Kimber L. Stamm Masias, Torin C. Peck, Charles A. Roberts
Demand for high-performing, inexpensive catalysts has motivated the development of mixed 3d transition metal architectures. Here, X-ray spectroscopies are uniquely positioned to inform intensive searches of compositional spaces by elucidating structure

2022 Topical Meeting on Optical Interference Coatings: Manufacturing Problem Contest

January 11, 2023
Author(s)
Catherine Cooksey, Daniel Poitras, Luke Sandilands, Penghui Ma, Stacey Lee, Michael Jacobson
Participants to the 2022 Manufacturing Contest were challenged to fabricate an optical filter with a specified stepped transmittance spanning three orders of magnitude from 400 nm to 1100 nm. The problem required that contestants be equally versed in the

3D Asymmetric Bilayer Garnet-Hybridized High-Energy-Density Lithium-Sulfur Batteries

Changmin Shi, Tanner Hamann, Saya Takeuchi, George Alexander, Adelaide M. Nolan, Matthew Limpert, Zhezhen Fu, Jonathan O'Neill, Griffin Godbey, Joseph A. Dura, Eric Wachsman
Lithium garnet Li 7La 3Zr 2O 12 (LLZO) with high ionic conductivity and chemical stability against a Li metal anode is considered one of the most promising solid electrolytes for lithium-sulfur batteries. However, an infinite charge time resulting in low

Defining Chi for Block Copolymer Lithography

January 11, 2023
Author(s)
Whitney Loo, Hongbo Feng, Thomas Ferron, Ricardo Ruiz, Daniel Sunday, Paul Nealey
Block copolymer lithography, such as directed self-assembly, requires the design of nanostructured block copolymers with precise values of segregation strength, 20≤χN≤25, in order to balance covarying material properties and meet manufacturing requirements

Hydration of a side-chain-free n-type ladder semiconducting polymer driven by electrochemical doping
