Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Xolography for Rapid Volumetric Production of Objects from the Nanoscopic to Macroscopic Length Scales

open access: yesAdvanced Materials, EarlyView.
This article explores the development of materials with multi‐scale control at the nanoscale (<100 nm), micrometer‐scale (80 µm), and macro‐scale (multi‐component geometries). This is achieved by applying polymerization‐induced microphase separation (PIMS) process via volumetric 3D printing (Xolography), expanding the design space for functional ...

Drug-induced Immunological Tolerance [PDF]

open access: possibleNature, 1959
PREVIOUS work in this laboratory demonstrated that administration of a purine analogue, 6-mercaptopurine, suppressed the antibody response to a soluble antigen (human serum albumin) in rabbits1. It was shown that the antimetabolite could block completely the primary immune response to the purified protein antigen; its effect on the secondary response ...

Tolerance to Drugs, especially to Morphine [PDF]

open access: possibleNature, 1960
VARIOUS theories have been put forward to elucidate the development of tolerance to a drug. For example, it has been observed by Zauder1 that “as tolerance develops (in the rat), the amount of morphine appearing in the urine decreases”. This was in accordance with Gross and Thomson's observations on the dog2. Cochin et al.

Tolerance and cross-tolerance among psychotomimetic drugs

Psychopharmacologia, 1968
A fixed-ratio schedule of milk reinforcement (FR 30) was used to study tolerance to the effects of d-LSD, l-LSD, BOL, psilocybin, mescaline, and d-amphetamine in the rat. A decrease in the amount of disruption of bar-pressing occurs with repeated daily administration of appropriate doses of all of the “psychotomimetic” compounds, and cross-tolerance ...

Occasion setting and drug tolerance

Integrative Physiological & Behavioral Science, 2002
There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance.
