Zero-Baseline Measurements for Relative Positioning in Vehicular Environments [PDF]

, 2013
Forward collision warning systems, lane change assistants or cooperative adaptive cruise control are examples of safety relevant applications that rely on accurate relative positioning between vehicles.

Exploiting additional actuators and sensors for nano-positioning robust motion control

, 2014
The ongoing need for miniaturization and an increase of throughput in IC-manufacturing is obstructed by performance limitations in motion control of nano-positioning wafer stages.

Optimal Control on Positive Cones

2024 IEEE 63rd Conference on Decision and Control (CDC)
An optimal control problem on finite-dimensional positive cones is stated. Under a critical assumption on the cone, the corresponding Bellman equation is satisfied by a linear function, which can be computed by convex optimization. A separate theorem relates the assumption on the cone to the existence of minimal elements in certain subsets of the dual ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Root characteristics and soil microbial entropy can be important indicators of degradation of Populus simonii in sandy areas

Global Ecology and Conservation
Forests play a key role in global carbon sequestration, biodiversity conservation and ecological security, and their degradation weakens essential services such as wind breaking and sand fixation, especially in shelterbelts of arid and semi-arid sandy ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Periphytic biofilm at saline soil-water interface captured more cadmium than at non-saline ones: process, mechanism, and implication

Environmental Chemistry and Ecotoxicology
Soil salinity inhibits rice growth and enhances cadmium (Cd) mobility, threatening rice production and human health. Periphytic biofilm (PB), widely distributed at the soil-water interface of paddy filed, exhibits strong Cd capture capability.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]

, 2011
We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.
