Alkali-Active Sand Slate Powder for Use as Mineral Admixture in Mass Hydraulic Concrete: Technical and Economic Analysis

open access: yesAdvances in Materials Science and Engineering, 2021
This work has launched a comprehensive investigation on the macro performance and micro structure of mass concrete produced with alkali-active sand slate powder (ASSP) for use as the mineral admixture and a thorough analysis on its technical and economic

A novel small molecule, AS1, reverses the negative hedonic valence of noxious stimuli

open access: yesBMC Biology, 2023
Background Pain is the primary reason people seek medical care, with chronic pain affecting ~ 20% of people in the USA. However, many existing analgesics are ineffective in treating chronic pain, while others (e.g., opioids) have undesirable side effects.

Structured data structures [PDF]

open access: yesCommunications of the ACM, 1974
Programming systems which permit arbitrary linked list structures enable the user to create complicated structures without sufficient protection. Deletions can result in unreachable data elements, and there is no guarantee that additions will be performed properly.

Achieving gas pressure-dependent luminescence from an AIEgen-based metal-organic framework

open access: yesNature Communications, 2022
Compounds displaying aggregation-induced emission behavior may have application in the preparation of smart materials. Here, the authors report a luminogen-containing metal-organic framework for which luminescence intensity changes are observed in ...

Developmental changes in the accessible chromatin, transcriptome and Ascl1-binding correlate with the loss in Müller Glial regenerative potential

open access: yesScientific Reports, 2020
Diseases and damage to the retina lead to losses in retinal neurons and eventual visual impairment. Although the mammalian retina has no inherent regenerative capabilities, fish have robust regeneration from Müller glia (MG). Recently, we have shown that

Structures and Structural Realism [PDF]

open access: yesLogic Journal of the IGPL, 2005
Summary: The `ontic' form of structural realism (OSR), roughly speaking, admits a complete elimination of the objects in the discourse of scientific theories, leaving us with structures only. As put by the defenders of such a claim, the idea is that all there is are structures and, if the relevant structures are to be set-theoretical constructs ...

Superconducting nonlinear transport in optically driven high-temperature K3C60

open access: yesNature Communications, 2023
Optically driven quantum materials exhibit a variety of non-equilibrium functional phenomena, which to date have been primarily studied with ultrafast optical, X-Ray and photo-emission spectroscopy.

Improper High‐Tc Perovskite Ferroelectric with Dielectric Bistability Enables Broadband Ultraviolet‐to‐Infrared Photopyroelectric Effects

open access: yesAdvanced Science, 2023
The photopyroelectric effect in ferroelectrics has shown great potential for application in infrared detection and imaging. One particular subclass is broadband with dielectric bistability, which allows for large pyroelectric figures‐of‐merit (FOMs ...

Assembly and maintenance of GABAergic and Glycinergic circuits in the mammalian nervous system

open access: yesNeural Development, 2018
Inhibition in the central nervous systems (CNS) is mediated by two neurotransmitters: gamma-aminobutyric acid (GABA) and glycine. Inhibitory synapses are generally GABAergic or glycinergic, although there are synapses that co-release both ...
