The Magic Permutohedron

open access: yesThe Mathematical Intelligencer, 2023
We present a configuration called a magic permutohedron that shows the placement of the numbers of $\{1, 2, 3, \dots, 24\}$ in the vertices of the permutohedra so that the sum of numbers on each square side is 50 and the sum of the numbers in each hexagonal side is 75.

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

open access: yesAdvanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Constraining Dark Matter lifetime with a deep gamma-ray survey of the Perseus Galaxy Cluster with MAGIC

open access: yes, 2019
This work is dedicated to the search of dark matter in the Perseus Galaxy Cluster with MAGIC: Clusters of galaxies are the largest known gravitationally bound structures in the Universe, and most of their masses comes in the form of dark matter.

magic-sph/magic: release MagIC 6.1

open access: yes, 2021
Now support input resolution in spectral space directly specifying l_max and m_max. This now also works with m_max /= l_max. Implement support for a linearized version of MagIC to speed-up the estimate of critical Rayleigh numbers. Use it with mode=5 and

Origin of Magic Angles in Twisted Bilayer Graphene. [PDF]

open access: yesPhysical Review Letters, 2018
Twisted bilayer graphene (TBG) was recently shown to host superconductivity when tuned to special "magic angles" at which isolated and relatively flat bands appear.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Gut microbiome composition and strain-sharing in multiplex autism spectrum disorder families

open access: yesNature Communications
Autism spectrum disorder (ASD) is associated with alteration of gut microbiome, but the influence of familial structure on it remains poorly understood.

Serbian bioethics from an international perspective: Genetics and bioethics [PDF]

open access: yesFilozofija i Društvo, 2012
Global interests in bioethics have increased drastically since the end of 20th century. The reason for this should be ascribed to a broad application of molecular-genetic methods introduced in human bio-medicine.

Observations of Extragalactic Sources with the MAGIC Telescope.

open access: yes, 2006
MAGIC is currently the world's largest single dish ground based imaging atmospheric Cherenkov telescope. During the first year of operation, more than 20 extragalactic sources have been observed and several of them detected.
