Influence of Jumboizing on Propulsive Performance

JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1999
This paper is concerned with the influence of hull elongation on engine and propulsive performance. Though propulsive performance is known to relate closely to the principle dimensions of a ship, it is not yet clear how ship length can influence the performance of CPP (controllable pitch propeller) ship and FPP (fixed pitch propeller) ship, both of ...

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 ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

On the Effect of a Rudder on Propulsive Performance

Journal of the Society of Naval Architects of Japan, 1981
In designing a ship, it is important to estimate the effects of the propeller-rudder interaction, as the rudder behind a propeller has a great effect on the propulsive performance of a ship. This interaction problem has been treated theoretically by applying the thin wing theory to the rudder, and the hydrodynamical forces have been discussed.In this ...

Fundamental considerations in the design and performance assessment of propulsive fuselage aircraft concepts [PDF]

Propulsive fuselage aircraft complement the two under-wing turbofans of current aircraft with an embedded propulsion system within the airframe to ingest the energy-rich fuselage boundary layer.

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).

Translating whole‐genome doubling into precision medicine in cancer

Molecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)
