Increase of data and development of science [PDF]

روش شناسی علوم انسانی, 2019
Despite what it may seem, some indicators show that during the last quarter of twentieth-century science has been in the state of stagnation and there is less news about big discoveries.

Investigation of Exothermic Behaviors of Energetic Particles in Microfluidics Channels

Advanced Materials Technologies, EarlyView.
Scheme and representative frames of delivery, ignition, and combustion process of core@shell Al@CuO energetic material in a microchannel. The electrical discharge occurred at the throat of microchannel leads to the combustion of the energetic reaction, causing the formation of high‐momentum butterfly‐shaped jet at the throat.

Liquidity traps, learning and stagnation [PDF]

European Economic Review, 2008
We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead to deflationary spirals with falling prices and falling ...

Solvent‐Free Mechanocatalytic Reduction of Nitro Compounds with Hydrogen Gas and its Application in the Synthesis of Drugs and their Intermediates

Advanced Synthesis &Catalysis, EarlyView.
A solvent‐free mechanochemical reduction of nitro compounds using hydrogen gas is presented. In addition to enabling the synthesis of a variety of functionalized aniline derivatives, the method has been scaled up to gram quantities, evaluated for trace metal impurities, and applied to the synthesis of pharmaceutical compounds and their precursors.

Delayed Release of Intracellular Microcystin Following Partial Oxidation of Cultured and Naturally Occurring Cyanobacteria

Toxins, 2020
Oxidation processes can provide an effective barrier to eliminate cyanotoxins by damaging cyanobacteria cell membranes, releasing intracellular cyanotoxins, and subsequently oxidizing these toxins (now in extracellular form) based on published reaction ...

Adipocytes Promote Cisplatin Resistance through Secreting A1BG and Regulating NAMPT/PARP1 Axis‐Mediated DNA Repair in Osteosarcoma

Advanced Science, EarlyView.
The proposed working model for how adipocytes participate in cisplatin resistance in osteosarcoma. The adipocytes secret A1BG and stabilize NAMPT, leading to increased NAD⁺ levels and subsequent increased PARP1‐mediated DNA repair, resulting in cisplatin resistance in osteosarcoma finally.

A Multi‐Property Optimizing Generative Adversarial Network for de novo Antimicrobial Peptide Design

Advanced Science, EarlyView.
A Multi‐Property Optimizing Generative Adversarial Network (MPOGAN) is proposed to iteratively learn the relationship between peptides and multiple properties using a dynamically dataset. As the quality of the dataset improves, MPOGAN's ability to design antimicrobial peptides (AMPs) with multiple desired properties is enhanced.

e-Government Lessons from South Africa 2001-2011: Institutions, State of Progress and Measurement

The African Journal of Information and Communication, 2012
Electronic governance is the future of public governance globally. Governments that do not make the transition from paper-based systems of public administration to electronic platforms of public governance may swiftly undermine their chances of ...

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, EarlyView.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Real Income Stagnation of Countries, 1960-2001 [PDF]

We examine the phenomenon of real-income stagnation in a large cross-section of countries during the last four decades. Stagnation is defined as negligible or negative growth extending over a number of years.
