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 ...

Seeing the Unseen: Real-Time Micro-Expression Recognition with Action Units and GPT-Based Reasoning

Applied Sciences
This paper presents a real-time system for the detection and classification of facial micro-expressions, evaluated on the CASME II dataset. Micro-expressions are brief and subtle indicators of genuine emotions, posing significant challenges for automatic

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Deep reinforcement learning for energy maximization in AWS wave energy systems with supercapacitor storage unit

Ain Shams Engineering Journal
A deep deterministic policy gradient (DDPG)-based reinforcement learning (RL) controller is presented in this research to maximize the energy yield of the Archimedes Wave Swing (AWS) wave energy converter (WEC).

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

A Multi-Source Data Fusion-Based Method for Safety Monitoring of Construction Workers on Concrete Placement Surfaces

Buildings
Concrete placement surfaces are characterized by intensive construction processes, frequent equipment interactions, and strong spatial dynamics, which make it difficult to identify unsafe actions of construction workers in real time and to accurately ...

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Continuous-time multi-agent pathfinding with connectivity constraints

Complex & Intelligent Systems
Multi-Agent Pathfinding in continuous time (MAPF $$_{R}$$ R ) is the problem of computing collision-free trajectories for multiple agents moving in continuous space and time without discretizing time into time steps and unit-duration actions.

Failure case study on reheater pipes in a subcritical unit served for a thermal power plant

Case Studies in Thermal Engineering
Leakage failure occurred in the reheater pipe of a subcritical unit after 9 years operation, but didn't reach the design lifespan. Multi test and analysis methods were applied to find the failure reason and mechanism.
