Natural Variation and Neuromechanical Systems [PDF]

open access: yes, 2009
Natural variation plays an important but subtle and often ignored role in neuromechanical systems. This is especially important when designing for living or hybrid systems \ud which involve a biological or self-assembling component.

Variational Methods [PDF]

open access: yes, 2015
This contribution presents derivative-based methods for local sensitivity analysis, called Variational Sensitivity Analysis (VSA). If one defines an output called the response function, its sensitivity to inputs variations around a nominal value can be studied using derivative (gradient) information.

Modulated Expression of the Protein Kinase GSK3 in Motor and Dopaminergic Neurons Increases Female Lifespan in Drosophila melanogaster

open access: yesFrontiers in Genetics, 2020
Most eukaryotic genes express multiple transcripts and proteins, and a sophisticated gene expression strategy plays a crucial role in ensuring the cell-specificity of genetic information and the correctness of phenotypes. The Drosophila melanogaster gene

A Millennial-Scale Tephra Event-Stratigraphic Record of the South China Sea since the Penultimate Interglacial

open access: yesLithosphere, 2022
Large volcanic eruptions have significant impacts on climate and environmental changes. The deposition of tephra in marine sediments may serve as an eruption recorder, but it has not been extensively studied in the western Pacific.

Statistical analysis of dynamic behavior of continental shelf wave motions in the northern South China Sea [PDF]

open access: yesOcean Science, 2023
This study aims to analyze statistical behavior of the continental shelf wave motions, including continental shelf waves (CSWs) and arrested topographic waves (ATWs), in the northern South China Sea. The baseline consists of tide-gauge data from stations

Functional brain network mechanism of executive control dysfunction in temporal lobe epilepsy

open access: yesBMC Neurology, 2020
Background Executive control dysfunction is observed in a sizable number of patients with temporal lobe epilepsy (TLE). Neural oscillations in the theta band are increasingly recognized as having a crucial role in executive control network.

The Diagenetic Alterations of Historic Skeletons from the Crown Mines Cemetery, South Africa

open access: yesBiology, 2023
Human skeletons associated with early gold mining in Johannesburg, South Africa are investigated. An unmarked cemetery was buried beneath a mine dump which resulted in macroscopically stained and poorly preserved bones.

Increasing eutrophication driven by the increase of phosphate discharge in a subtropical bay in the past 30 years

open access: yesFrontiers in Marine Science, 2023
Although great efforts have been made to decrease nutrient (notably nitrogen and phosphorus) loads and lighten related environmental damages, coastal eutrophication remains a persistent environmental crisis.

Linkage variation and chromosome maps [PDF]

open access: yes, 1921
A recent paper in this journal by Detlefsen(1) is introduced as follows: "There is a well intrenched concept of recent genetics that hereditary factors or genes may be given fairly definite loci on chromosome maps and that these maps correspond to or ...
