Renormalization of the bilocal sine-Gordon model [PDF]

, 2018
The functional renormalization group treatment is presented for the two-dimensional sine-Gordon model by including a bilocal term in the potential, which contributes to the flow at tree level. It is shown that the flow of the bilocal term can substitute the evolution of the wave function renormalization constant, and then the Kosterlitz-Thouless type ...

Cerebrospinal Fluid Biomarkers in Opioid Dependence: Evidence of Neuroimmune Activation and Ion Composition Changes, Without Alteration in Orexin‐A

Addiction Biology, Volume 30, Issue 6, June 2025.
Cerebrospinal fluid from individuals with opioid dependence shows elevated neuroinflammatory biomarkers, indicating CNS immune activation. ABSTRACT Opioid abuse is a severe global health challenge, leading to rising morbidity, mortality, and increasing societal costs.

A Simplified Suspension Calculus and its Relationship to Other Explicit Substitution Calculi [PDF]

arXiv, 2007
This paper concerns the explicit treatment of substitutions in the lambda calculus. One of its contributions is the simplification and rationalization of the suspension calculus that embodies such a treatment. The earlier version of this calculus provides a cumbersome encoding of substitution composition, an operation that is important to the efficient

Over 1200 drugs-related deaths and 190,000 opiate-user-years of follow-up : relative risks by sex and age-group [PDF]

, 2010
Heroin users/injectors' risk of drugs-related death by sex and current age is weakly estimated both in individual cohorts of under 1000 clients, 5000 person-years or 50 drugs-related deaths and when using cross-sectional data.

Substitution and Complementarity in the Consumption of Alcohol, Cannabis, and Opium

Health Economics, Volume 34, Issue 5, Page 827-854, May 2025.
ABSTRACT Understanding the behavior of populations of drug consumers has been and remains a topic of keen interest. Using a unique dataset on 25 districts from Bengal, India, from 1911 to 1925, we analyze whether populations of consumers treat alcohol, cannabis, and opium as economic substitutes or complements in a legal regime.

Opioid Atlas: Mapping Access to Pain Medication [PDF]

arXiv, 2016
Opiates are some of the most effective pain relief medications available for patients suffering from cancer and surgery-related pain. Despite the affordability and effectiveness of these medications, access to opiates is highly geographically variable. Pain researchers have attributed geographic variation to various factors including the fear of opioid

High Throughput Pharmacovigilance Screening for Roflumilast Adverse Effects in Real‐World Settings: A Sequence Symmetry Analysis

Basic &Clinical Pharmacology &Toxicology, Volume 136, Issue 5, May 2025.
ABSTRACT Background Roflumilast is an add‐on therapy for COPD following exacerbations, but real‐world safety data in the United States are limited. Objective This study aimed to identify safety signals associated with roflumilast initiation through a high‐throughput signal detection algorithm. Methods Using sequence symmetry analysis (SSA), we analysed
