A hexahomotrioxacalix[3]arene-based ditopic receptor for alkylammonium ions controlled by Ag + ions 4 [PDF]

open access: yes, 2018
A receptor cone-1 based on a hexahomotrioxacalix[3]arene bearing three pyridyl groups 21 was successfully synthesized, which has a C3-symmetric conformation and is capable of binding 22 alkylammonium and metal ions simultaneously in a cooperative fashion.

Enhancing C3 Photosynthesis [PDF]

open access: yesPlant Physiology, 2010
A new “green revolution” is needed in world agriculture to increase crop yields for food and bioenergy, because gains from conventional crop improvement ([Fischer and Edmeades, 2010][1]) are less than world population growth.

Entanglement-assisted quantum error-correcting codes over arbitrary finite fields [PDF]

open access: yes, 2019
We prove that the known formulae for computing the optimal number of maximally entangled pairs required for entanglement-assisted quantum error-correcting codes (EAQECCs) over the binary field hold for codes over arbitrary finite fields as well. We also

Predicting Customer Churn and Retention Rates in Nigeria’s Mobile Telecommunication Industry Using Markov Chain Modelling

open access: yesActa Universitatis Sapientiae: Economics and Business, 2015
The telecommunication industry is one of the service industries that is most affected by the problem of subscribers’ churn. Although several techniques have been used to predict customer churn in developed countries, many of those studies used secondary ...

C3 glomerulopathies: dense deposit disease and C3 glomerulonephritis

open access: yesFrontiers in Medicine, 2023
Dense deposit disease (DDD) and C3 glomerulonephritis (C3GN) are types of membranoproliferative glomerulonephritis classified as C3 glomerulopathies. These conditions are characterized by an increased number of intraglomerular cells and diffuse thickening of the glomerular capillary walls, along with the deposition of C3 and minimal or absent ...

Tars: Timeliness-aware Adaptive Replica Selection for Key-Value Stores

open access: yes, 2017
In current large-scale distributed key-value stores, a single end-user request may lead to key-value access across tens or hundreds of servers. The tail latency of these key-value accesses is crucial to the user experience and greatly impacts the revenue.
