Deep-Learning-Aided Distributed Clock Synchronization for Wireless Networks [PDF]

open access: yesarXiv, 2022
The proliferation of wireless communications networks over the past decades, combined with the scarcity of the wireless spectrum, have motivated a significant effort towards increasing the throughput of wireless networks. One of the major factors which limits the throughput in wireless communications networks is the accuracy of the time synchronization

Vertical Integration from the Large Hilbert Space

open access: yes, 2017
We develop an alternative description of the procedure of vertical integration based on the observation that amplitudes can be written in BRST exact form in the large Hilbert space. We relate this approach to the description of vertical integration given

Pitfalls and Strategies for Measuring Menopausal Stage in Eating Disorder Studies of Women in Midlife

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Researchers are increasingly interested in exploring the role of the menopausal transition in eating disorder risk. We recently embarked on studies of this critical life phase and encountered significant challenges in assessing menopausal status that limited our ability to test study hypotheses.

Mechanistic Insights Into the Methoxycarbonylation of Technical Grade Oleochemicals: Catalytical and Structural Analysis of Conjugated Fatty Acid Methyl Esters

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
In this study, the inhibitory effect of PU‐FAME on methoxycarbonylation was analyzed. It could be shown that conjugated FAME products in particular are responsible for the observed inhibition. ABSTRACT This study examines the valorization of vegetable oils through Pd‐catalyzed methoxycarbonylation.

Research on Optimal Charge Structure Selection and Active Control Methods for Subgrade Bench Blasting Based on Multi‐Objective Optimization

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT To reduce the peak vibration velocity (PPV) of subgrade bench blasting vibration, the control variable method was used to analyze the blasting effect of different charging methods. Initially, the control variable method was used to evaluate the blasting performance of different charge structures.

Health related quality of life in women with Polycystic Ovary Syndrome (PCOS)

open access: yesPayesh, 2012
Objective (s): Polycystic ovary syndrome (PCOS) is a disorder of hyperandrogenemia and chronic anovulation which affects 5-10% of all women. The PCOS symptoms such as hirsutism, irregular menses, obesity and infertility are a major source of ...

Analytic Approximations for Three Neutrino Oscillation Parameters and Probabilities in Matter [PDF]

open access: yes, 2001
The corrections to neutrino mixing parameters in the presence of matter of constant density are calculated systematically as series expansions in terms of the mass hierarchy $\dm{21}/\dm{31}$.

Challenges and Perspectives on Photocatalytic Membrane Reactors for Volatile Organic Compounds Degradation and Nitrogen Oxides Treatment

open access: yesGlobal Challenges, EarlyView.
Photocatalytic membrane reactors (PMRs) find the synergy of membranes as flexible, stable, permeable hosts to incorporate photocatalytic materials. This combination has strong potential in air purification systems, particularly the decontamination of air via reactive‐species‐induced degradation of volatile organic compounds and nitrogen oxides.

An Attack-Resilient Pulse-Based Synchronization Strategy for General Connected Topologies [PDF]

open access: yesarXiv, 2020
Synchronization of pulse-coupled oscillators (PCOs) has gained significant attention recently due to increased applications in sensor networks and wireless communications. Given the distributed and unattended nature of wireless sensor networks, it is imperative to enhance the resilience of pulse-based synchronization against malicious attacks. However,

On the norms of quaternionic harmonic projection operators [PDF]

open access: yes, 2018
As a consequence of integral bounds for three classes of quaternionic spherical harmon-ics, we prove some bounds from below for the (Lp,L2) norm of quaternionic harmonic projectors, for p between 1 and ...
