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

open access: yesMolecular 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 ...

Design and Study on the Cutting Structure of Rotary Cutting PDC Bit

open access: yesShiyou jixie, 2020
The rotary cutting PDC bit can well adapt to deep high-plasticity strata. In this paper, the cutting performance of rotary cutting PDC bit was investigated by means of experiment and simulation.

Research into mechanical modeling based on characteristics of the fracture mechanics of ice cutting for scientific drilling in polar regions [PDF]

open access: yesThe Cryosphere
Scientific drilling in polar regions plays a crucial role in obtaining ice cores and using them to understand climate change and to study the dynamics of polar ice sheets and their impact on global environmental changes (sea level, ocean current cycle ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Cutting Force Prediction in Drilling of Titanium Alloy

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Cutting force in drilling of Ti-6Al-4V is studied with simulation based on a predictive model. In the force model, three-dimensional chip flow is made by piling up the orthogonal cuttings in the planes containing the cutting velocities and the chip flow ...

Tactile perception by tissue force characteristics for robotic red eat cutting [PDF]

open access: yes
This research investigates an approach to tactile perception for guiding a cutting tool attached to a robotic system processing red meat. Conventional tactile sensing methods, reliant solely on spatial force values, have met with inconsistent results ...

Analysing the Impact of Cutting Force and Vibration on Surface Roughness in External Cylindrical Grinding of SKH2 Stell

open access: yes, 2023
The surface roughness of a part during external cylindrical grinding is directly impacted by cutting force and vibration, which are intermediate parameters. To improve the quality of finished parts, studying and controlling these parameters is essential.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

An investigation on the mechanics of nanometric cutting and the development of its test-bed

open access: yes, 2003
The mechanics of machining at a very small depth of cut (100 nm or less) is not well understood. The chip formation physics, cutting forces generation, resulting temperatures and the size effects significantly affect the efficiency of the process and ...
