On the fourth power mean of the generalized three-term exponential sums

open access: yes四川大学学报. 自然科学版, 2020
This paper aims at calculation of the fourth power mean of a certain generalized three-term exponential sums modulo p, an odd prime.By using some properties of the classical Gauss sums and character sums, we give some exact calculating formulae and ...

Selected Indices of Anaerobic Capacity and Their Changes during Special Judo Fitness Tests at Different Ambient Temperatures Performed among Judo Athletes

open access: yesApplied Sciences, 2022
Background: Thermoregulatory processes play an important role during athletic competition. When athletes compete in an elevated ambient temperature, metabolic processes in their bodies become intensified.

The \u1d716-normalized sign regressor least mean fourth (NSRLMF) adaptive algorithm

open access: yes, 2012
In this paper, a new algorithm, the ∈-normalized sign regressor least mean fourth (NSRLMF) algorithm is presented as a substitute for the ∈-normalized least mean fourth (NLMF) algorithm.

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distributed a 121‐question survey to radiation oncologists, medical physicists and ...

Mode identification of low‐frequency oscillations in power systems based on fourth‐order mixed mean cumulant and improved TLS‐ESPRIT algorithm

open access: yesIET Generation, Transmission & Distribution, 2017
Wide area monitoring systems (WAMS) provide effective support for online identification of low‐frequency oscillations in power systems. The WAMS signal is sensitive to the surrounding environment, and it contains Gaussian white noise.

Adaptive channel equalization using the sign regressor least mean fourth algorithm

open access: yes, 2011
In this paper, the performance analysis of the least mean fourth (LMF) algorithm and the sign regressor least mean fourth (SRLMF) algorithm is investigated in an adaptive channel equalization scenario.

Living and Working Safely Around High-Voltage Power Lines. [PDF]

open access: yes, 1998
High-voltage transmission lines can be just as safe as the electrical wiring in the homes--or just as dangerous. The crucial factor is ourselves: they must learn to behave safely around them.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
