A Deep Learning Reconstruction Framework for Differential Phase-Contrast Computed Tomography with Incomplete Data

open access: yes, 2019
Differential phase-contrast computed tomography (DPC-CT) is a powerful analysis tool for soft-tissue and low-atomic-number samples. Limited by the implementation conditions, DPC-CT with incomplete projections happens quite often.

An improved probability propagation algorithm for density peak clustering based on natural nearest neighborhood

open access: yesArray, 2022
Clustering by fast search and find of density peaks (DPC) (Since, 2014) has been proven to be a promising clustering approach that efficiently discovers the centers of clusters by finding the density peaks.

Writing on Dirty Paper with Resizing and its Application to Quasi-Static Fading Broadcast Channels

open access: yes, 2007
This paper studies a variant of the classical problem of ``writing on dirty paper'' in which the sum of the input and the interference, or dirt, is multiplied by a random variable that models resizing, known to the decoder but not to the encoder.

Identification of side population cells in mouse primordial germ cells and prenatal testis [PDF]

open access: yes, 2011
In mammals, the stem cells of spermatogenesis are derived from an embryonic cell population called primordial germ cells (PGCs). Spermatogonial stem cells displaying the "side population" (SP) phenotype have been identified in the immature and adult ...

Clean relaying aided cognitive radio under the coexistence constraint

open access: yes, 2011
We consider the interference-mitigation based cognitive radio where the primary and secondary users can coexist at the same time and frequency bands, under the constraint that the rate of the primary user (PU) must remain the same with a single-user ...

A new PI(1 +PI) controller to mitigate power ripples of a variable-speed dual-rotor wind power system using direct power control

open access: yesEnergy Reports, 2023
This work presents a new scheme of direct power command (DPC) of induction generator (IG)-based dual-rotor wind power (DRWP) systems. The suggested DPC employs a proportional-integral (1 + proportional-integral) controller (PI(1 +PI)) to regulate the IG ...

Voltage-dependent Block of the Cystic Fibrosis Transmembrane Conductance Regulator Cl- Channel by Two Closely Related Arylaminobenzoates [PDF]

open access: yes, 1993
The gene defective in cystic fibrosis encodes a Cl- channel, the cystic fibrosis transmembrane conductance regulator (CFTR). CFTR is blocked by diphenylamine-2-carboxylate (DPC) when applied extracellularly at millimolar concentrations.
