Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Determination of Thermal DNA‐Stability With Respect to PCR or How to Debunk a Pseudoscientific Claim

open access: yesBiochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Debunking pseudoscience is difficult, especially for early‐career students and the public. Recently, in particular the Corona pandemic has spawned a whole range of pseudoscientific claims and conspiracy theories, many of which are publicly available in the style of scientific articles on preprint servers, in predatory journals, or in some ...

Global Range Estimates for Maximal Oscillatory Integrals with Radial Testfunctions [PDF]

open access: yes, 2011
We consider the maximal function of oscillatory integrals and prove a global estimate for radial test functions which is almost sharp with respect to the Sobolev regularity.Comment: Preprints in Mathematical Sciences 2011:1 ISSN 1403-9338, LUNFMA-5068 ...

Nucleation Rate of Hadron Bubbles in Baryon-Free Quark-Gluon Plasma

open access: yes, 1995
We evaluate the factor $\kappa$ appearing in Langer's expression for the nucleation rate extended to the case of hadron bubbles forming in zero baryon number cooled quark-gluon plasma.

Fractal Anatomy of Human Organs: A Narrative Review of Structure, Function, and Clinical Perspectives

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Fractal geometry describes complex, self‐similar patterns that repeat across spatial scales and is increasingly recognized as relevant in anatomical research. Indeed, the fractal organization is consistently observed in respiratory, cardiovascular, gastrointestinal, nervous, renal, hepatic, and dermatological systems.

Universal behaviour of the SU(2) running coupling constant in the continuum limit

open access: yes, 1994
We present data from the ALPHA Collaboration about lattice calculation of SU(2) pure--gauge running coupling constant, obtained with two different definitions of the coupling itself, which show universality of the continuum limit and clarify the ...

One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

open access: yesChemistry – A European Journal, EarlyView.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...

Preprints Involving Medical Research-Do the Benefits Outweigh the Challenges?

open access: yesJournal of the American Medical Association (JAMA), 2020
A preprint is a complete manuscript posted to a preprint server by authors before peer review and publication in a journal. The goals of preprints are to enable authors to obtain timely feedback and comments on research before submission to a peer ...

Threshold amplitudes in field theories and integrable systems

open access: yes, 1995
We discuss the threshold tree amplitudes in diverse nonintegrable quantum field theories in the framework of integrability. The amplitudes are related to some Baker functions defined on the auxiliary spectral curves and the nullification phenomena are ...
