Small Angle Scattering by Fractal Aggregates: A Numerical Investigation of the Crossover Between the Fractal Regime and the Porod Regime

open access: yes, 1995
Fractal aggregates are built on a computer using off-lattice cluster-cluster aggregation models. The aggregates are made of spherical particles of different sizes distributed according to a Gaussian-like distribution characterised by a mean $a_0$ and a ...

Novel Higgs decay signals in R-parity violating models [PDF]

open access: yes, 2008
In supersymmetric models the lightest Higgs boson may decay with a sizable branching ratio into a pair of light neutralinos. We analyze such decays within the context of the minimal supersymmetric standard model with R-parity violation, where the ...

Přirozenost u porodu – příklady provázanosti kultury a biologie pohledem porodní asistentky

open access: yesFilosofie Dnes
Porod je významnou událostí na počátku života každého z nás. Období kolem porodu je kritickým obdobím pro budoucí zdraví ženy i dítěte, i celých dalších generací. Porod, a především jeho citlivá poporodní fáze, zároveň byl a je terčem různých kulturních

Dissipation and irreversibility in computing

open access: yesMaterials Research Express, 2023
There has been much discussion for decades over the proper concepts of minimum dissipation per logic gate and what is required for computation, as well as early arguments over logically reversible machines.

Polymer chain stiffness versus excluded volume: A Monte Carlo study of the crossover towards the wormlike chain model

open access: yes, 2010
When the local intrinsic stiffness of a polymer chain varies over a wide range, one can observe both a crossover from rigid-rod-like behavior to (almost) Gaussian random coils and a further crossover towards self-avoiding walks in good solvents.

Lepton flavor violation beyond the MSSM [PDF]

open access: yes, 2015
Most extensions of the Standard Model lepton sector predict large lepton flavor violating rates. Given the promising experimental perspectives for lepton flavor violation in the next few years, this generic expectation might offer a powerful indirect ...

Vpliv telesne vadbe v nosečnosti na pojavnost poporodne depresije

open access: yesObzornik zdravstvene nege
Uvod: Nove razmere, kakršen je porod, so fizično in psihično obremenjujoče, še posebej, če ženska v poporodnem obdobju doživi poporodno depresijo. Gre za najpogostejšo poporodno duševno motnjo, katere posledice so lahko dolgotrajne. Namen integrativnega

Influence of ionic conditions on knotting in a coarse-grained model for DNA

open access: yesFrontiers in Chemistry, 2023
We investigate knotting probabilities of long double-stranded DNA strands in a coarse-grained Kratky-Porod model for DNA with Monte Carlo simulations. Various ionic conditions are implemented by adjusting the effective diameter of monomers.
