Applicability of magnetic force models for multi-stable energy harvesters

Multi-stable piezoelectric energy harvesters have been exploited to enhance performance for extracting ambient vibrational energy from a broadband energy source. Since magnetic force plays a significant role in enhancing the...

​Forecast with Forecasts
Forecast combinations have been widely applied in the last few decades to improve forecasting. Estimating optimal weights that can outperform simple averages is not always an easy task. In recent years, the idea of using time...
Cracking the enigma of mitochondrial-DNA variants and cancer.
Wei Wei, Patrick F Chinnery
Feb 12, 2020
A recent study by Yuan et al., [Ref. 11] published in Nature Genetics, demonstrated multidimensional molecular alterations of mitochondrial DNA in human cancers and provide an on-line catalogue of mitochondrial genomes in many...

Probability and output analysis of asymmetric bistable energy harvesters subjected to Gaussian white noise

Due to their excellent broadband response and high sensitivity to low-amplitude excitations, there is significant interest in the theoretical analysis and experimental validation of bistable energy harvesters (BEHs). However...

Optimisation for interconnected energy hub system with combined ground source heat pump and borehole thermal storage
Da Huo, Wei Wei, Simon Le Blond
Dec 01, 2018
Ground source heat pumps (GSHP) give zero-carbon emission heating at a residential level. However, as the heat is discharged, the temperature of the ground drops, leading to a poorer efficiency. Borehole inter-seasonal thermal...

Multiple solutions of asymmetric potential bistable energy harvesters
In this paper, we investigate the multiple solutions of nonlinear asymmetric potential bistable energy harvesters (BEHs) under harmonic excitations. Basins of attraction under certain excitations explain the existence of...
Cell reprogramming shapes the mitochondrial DNA landscape.
Individual induced pluripotent stem cells (iPSCs) show considerable phenotypic heterogeneity, but the reasons for this are not fully understood. Comprehensively analysing the mitochondrial genome (mtDNA) in 146 iPSC and...

Biparental inheritance of mitochondrial DNA revisited.
Evidence for a biparental mode of mitochondrial DNA (mtDNA) inheritance has been sparse and remains controversial. Recent studies using a range of complementary techniques do not support paternal transmission of mtDNA, and...
Water Resources Assessment and Management for Nuclear Power Plants in China
To deal with global warming and energy shortage, nuclear power plants are constructed or planning to be constructed in China presently. The operation of a nuclear power plant consumes a great amount of water and discharges a lot...

Catalytic trajectory of a dimeric nonribosomal peptide synthetase subunit with an inserted epimerase domain.
Nonribosomal peptide synthetases (NRPSs) are modular assembly-line megaenzymes that synthesize diverse metabolites with wide-ranging biological activities. The structural dynamics of synthetic elongation has remained unclear....

Optimum resistance analysis and experimental verification of nonlinear piezoelectric energy harvesting from human motions

The complex dynamic behavior of nonlinear harvesters make it difficult to identify the optimum mechanical and electrical parameters for maximum output power, when compared to linear energy harvesting devices. In addition, the...

Optimal Borehole Energy Storage Charging Strategy in a Low Carbon Space Heat System

Domestic heating is the major demand of energy systems, which can bring significant uncertainties to system operation and shrink the security margin. From this aspect, the borehole system, as an interseasonal heating storage...

Performance enhancement of nonlinear asymmetric bistable energy harvesting from harmonic, random and human motion excitations

Numerical and experimental investigations of nonlinear bistable energy harvesters (BEHs) with asymmetric potential functions are presented under various excitations for performance enhancement. Basin of attraction under...
