Analysis on the Evolution of Reclamation Space and Benefit-oriented Mechanism of Shenzhen from 1980 to 2020

Haiyang Kaifa yu guanli
Reclamation space, as an important part connecting land and sea, is a key link in land-sea coordination. Taking Shenzhen as an example, by combing the Landsat remote sensing image data from 1980 to 2020, analyzing the scale of reclamation and the change ...

Calculating the torque on the shafts of the Antikythera Mechanism to determine the location of the driving gear

, 2018
The Antikythera Mechanism (AM) is considered by the scientific community to be the first computer ever built. Its operation is not entirely known, derived only by the existing fragments of the mechanism that have been found and studied.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Driving Performance and User's Evaluation of Self-Balancing Personal Mobility Vehicle with a Pedal Driving Mechanism

, 2015
In this paper, we propose a self-balancing personal mobility vehicle with a hybrid driving mechanism, called as Wi-PMP, and discuss its features from the perspectives of its power-assist driving performance and a rider's evaluation.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
