Greedy power allocation for multicarrier systems with reduced complexity [PDF]

, 2010
In this paper we consider a reduced complexity discrete bit loading for Multicarrier systems based on the greedy power allocation (GPA) under the constraints of transmit power budget, target BER, and maximum permissible QAM modulation order.

Structures of Native Doublet Microtubules from Trichomonas vaginalis Reveal Parasite-Specific Proteins

Nature Communications
Doublet microtubules (DMTs) are flagellar components required for the protist Trichomonas vaginalis (Tv) to swim through the human genitourinary tract to cause trichomoniasis, the most common non-viral sexually transmitted disease.

Management Guidelines for the Treatment of Pediatric Brain Tumor–Associated Seizure: A Modified Delphi Consensus Report

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Seizures represent a significant source of morbidity for children with brain tumors. The objective of our study was to establish consensus guidelines for managing children with tumor‐related epilepsy. Methods The study team assembled a panel of 18 child neurologists specializing in neurological complications of brain tumors including

DMT at fifty.

Neuropsychopharmacologia Hungarica : a Magyar Pszichofarmakologiai Egyesulet lapja = official journal of the Hungarian Association of Psychopharmacology, 2008
The steps taken for the discovery of the hallucinogenic effects of N.N-Dimethyl-tryptamine (DMT) is described. DMT had a difficult first 50 years in medical research primarily for legal reasons as it was classified as one of the "drugs of abuse" by authorities in the USA and by the World Health Organization.

Understanding Consumption of Illicit Drugs and New Psychoactive Substances in Australia by Triangulating Drug Checking and Wastewater‐Based Epidemiology

Drug Testing and Analysis, EarlyView.
First Australian study combining wastewater‐based epidemiology and drug checking, demonstrating how complementary data sources enhance monitoring of illicit drugs and emerging psychoactive substances during high‐use periods. ABSTRACT Consumption of psychotropic drugs is a major economic and public health challenge in Australia.

Pharmacological characterization of the bifunctional opioid ligand H-Dmt-Tic-Gly-NH-Bzl (UFP-505) [PDF]

, 2012
Background While producing good-quality analgesia, µ-opioid (MOP) receptor activation produces a number of side-effects including tolerance. Simultaneous blockade of ä-opioid (DOP) receptors has been shown to reduce tolerance to morphine.

Nickel‐Catalyzed LiF‐Rich Interface for Silicon Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Modulating the decomposition of F‐containing species in the electrolyte to form LiF‐rich SEI has been proven to be an effective strategy for interface optimization. Herein, through nickel‐catalyzed pyrolysis of carbon precursors on silicon, graphene‐like carbon was formed to construct three‐dimensional conductive networks.

Rapid Targeted Repair of the Solid Electrolyte Interphase via a Hybrid Ester‐Ether Solvation Strategy for Stable Sodium Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An ester‐ether hybrid solvation electrolyte is designed for targeted repair of the solid electrolyte interphase (SEI) on sodium anode. Preferential decomposition of the confined ester component at defect sites rapidly forms a robust composite SEI, effectively suppressing dendrites.

Simultaneous Enhancement of Mechanical and Dielectric Performance of Polypropylene Composites by Introducing an External Elastic Crystal

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A hierarchical crystalline structure for recyclable polypropylene insulation in high‐voltage cables is presented. This architecture integrates rigid isotactic polypropylene spherulites with an elastic crystalline network to balance load‐bearing capacity and ductility.

DMT micro-phenomenology

DMT reliably induces profound experiences of immersion in other worlds and encounters with seemingly autonomous presences, yet the lived qualities and unfolding of these experiences remain poorly understood. Using micro-phenomenological interviews with twenty-three healthy participants who received DMT during fMRI scanning, this study explores how ...
