Systematic Errors in Service Speed [PDF]

Journal of Navigation, 1972
An accurate knowledge of the service speed of a merchant vessel is becoming increasingly important. Service speed and average speed (the former traditionally implying a long-term average, the latter a short-term average) are both derived by dividing the sum of a number of observed distances by the relevant time elapsed.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Structure Tensor-Based Algorithm for Hyperspectral and Panchromatic Images Fusion

Remote Sensing, 2018
Restricted by technical and budget constraints, hyperspectral (HS) image which contains abundant spectral information generally has low spatial resolution. Fusion of hyperspectral and panchromatic (PAN) images can merge spectral information of the former

cISP: A Speed-of-Light Internet Service Provider

CoRR, 2018
Low latency is a requirement for a variety of interactive network applications. The Internet, however, is not optimized for latency. We thus explore the design of cost-effective wide-area networks that move data over paths very close to great-circle paths, at speeds very close to the speed of light in vacuum.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Mechanical behavior and energy absorption of expansion circular tube with negative Poisson’s ratio

Alexandria Engineering Journal
The expansion tube plays a crucial role in the field of train collision safety protection. In this study, we combine the expansion characteristics of negative Poisson’s ratio (NPR) with the deformation mechanism of the expansion tube to propose a novel ...

Service life of low-speed long-running stages of compressor units and possible ways of its increase [PDF]

Омский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение", 2019
The paper presents theoretical studies to increase the service life of piston seals made on the basis of fluoroplastic by changing the speed of movement of the piston and, accordingly, a more efficient cooling mode.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.
