School‐based health and nutrition interventions addressing double burden of malnutrition and educational outcomes of adolescents in low‐ and middle‐income countries: A systematic review

open access: yesMaternal &Child Nutrition, EarlyView., 2023
Abstract School system is a promising platform for addressing all forms of malnutrition in adolescents. However, little is known about the impact of integrated school health and nutrition programmes on adolescent nutrition and educational outcomes in low‐ and middle‐income countries (LMICs).

High energy cosmic-rays: puzzles, models, and giga-ton neutrino telescopes [PDF]

open access: yesPramana 62 (2004) 483-496, 2003
The existence of cosmic rays of energies exceeding 10^20 eV is one of the mysteries of high energy astrophysics. The spectrum and the high energy to which it extends rule out almost all suggested source models. The challenges posed by observations to models for the origin of high energy cosmic rays are reviewed, and the implications of recent new ...

On a Missed Mechanism of Dielectron Production in Nucleon-Nucleon Collisions

open access: yes, 2010
We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to \gamma^\star d^\star_1$, where $\gamma^\star$ is the virtual photon which converts ...

Advantages of horizontal centrifugation of platelet‐rich fibrin in regenerative medicine and dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract The aim of this comprehensive review was to evaluate comparative studies on horizontal and fixed‐angle centrifugation methods for preparing platelet‐rich fibrin (PRF). Furthermore, additional studies utilizing horizontal PRF (H‐PRF) were systematically investigated.

Evidence for Winding States in Noncommutative Quantum Field Theory [PDF]

open access: yes, 2000
We study noncommutative field theories at finite temperature to learn more about the degrees of freedom in the non-planar sector of these systems. We find evidence for winding states.

High‐intensity resistance training and collagen supplementation improve patellar tendon adaptations in professional female soccer athletes

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated whether 10 weeks of pre‐season soccer training (including high‐intensity resistance exercise) with hydrolysed collagen (COL) supplementation would confer greater changes in patellar tendon (PT) mechanical and material properties compared with placebo (PLA) in professional female soccer athletes.

A perspective on Quantum Gravity Phenomenology [PDF]

open access: yes, 2003
I give a brief overview of some Quantum-Gravity-Phenomenology research lines, focusing on studies of cosmic rays and gamma-ray bursts that concern the fate of Lorentz symmetry in quantum spacetime.

AMR‐Wind: A Performance‐Portable, High‐Fidelity Flow Solver for Wind Farm Simulations

open access: yesWind Energy, Volume 28, Issue 5, May 2025.
ABSTRACT We present AMR‐Wind, a verified and validated high‐fidelity computational‐fluid‐dynamics code for wind farm flows. AMR‐Wind is a block‐structured, adaptive‐mesh, incompressible‐flow solver that enables predictive simulations of the atmospheric boundary layer and wind plants.

Black Hole Formation and Classicalization in Ultra-Planckian 2 -> N Scattering [PDF]

open access: yes, 2015
We establish a connection between the ultra-Planckian scattering amplitudes in field and string theory and unitarization by black hole formation in these scattering processes.
