A lower bound on the data rate of dirty paper coding in general noise and interference

, 2014
Dirty paper coding (DPC) allows a transmitter to send information to a receiver in the presence of interference that is known (non-causally) to the transmitter. The original version of DPC was derived for the case where the noise and the interference are

Single‐Atom Photocatalyst as Floatable Artificial Leaf for Upcycling Oceanic Plastic Waste

Advanced Materials, EarlyView.
To resolve the catastrophic disaster of oceanic plastic pollution, the novel Ru single atom loaded ZnIn2S4 photocatalysts, in the forms of powder or floatable artificial leaf, were prepared for direct conversion of raw polypropylene plastic into valuable chemicals. The optimized catalyst exhibits exceptional performance, with a total formic/acetic acid

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

, 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.

An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids

Advanced Materials Technologies, EarlyView.
This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

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

Energy 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 ...

Clean relaying aided cognitive radio under the coexistence constraint

, 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 ...

Flux predictions of high-energy neutrinos from pulsars [PDF]

, 2006
Young, rapidly rotating neutron stars could accelerate ions from their surface to energies of $\sim 1$ PeV. If protons reach such energies, they will produce pions (with low probability) through resonant scattering with x-rays from the stellar surface ...

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

Advanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Direct primary care: Family physician perceptions of a growing model

Population Medicine, 2021
Introduction Direct Primary Care (DPC) is a relatively new primary care practice model in which patients receive unlimited access to a defined set of primary care services in exchange for a monthly practice-specific membership fee.
