A Low-Complexity Path Loss Prediction Model for Multi-UAV Communication in Urban Environments

IEEE Open Journal of Antennas and Propagation
Ray tracing method (RT) is a computational method for modeling light propagation and interaction, which can be used to simulate communication signal propagation, path loss, etc. in unmanned aerial vehicles (UAV).

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Interference Reduction by Millimeter Wave Technology for 5G-Based Green Communications

IEEE Access, 2016
The primary goal of this paper is the optimization of data transmissions and connections between 5G base stations (BSs) as well as the improvement of access technologies and transmission methods in consideration of massive multi-input multi-output, a key

Path loss models with distance‐dependent weighted fitting and estimation of censored path loss data [PDF]

IET Microwaves, Antennas & Propagation, 2016
Path loss models are the most fundamental part of wireless propagation channel models. Path loss is typically modelled as a (single‐slope or multi‐slope) power‐law dependency on distance plus a log‐normally distributed shadowing attenuation.

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 ...

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

Molecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Studying Corruption and Anticorruption in a Late Medieval Commune: The case of Thirteenth- and Fourteenth-century Bologna [PDF]

, 2023
This paper explores the historical meaning of corruption and its forms of contrast in late medieval Bologna. It focuses on understanding the different and changing notions this form of classifiable crime, performed by public officers, assumed in the ...

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.
