A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Extremal Branes as Elementary Particles [PDF]
The supersymmetric p-branes of Type II string theory can be interpreted after compactification as extremal black holes with zero entropy and infinite temperature.

Dependence of the cut-off parameters for the cluster reconstruction on incident momenta
In this work, firstly, we have determined the multiplicities of protons that are involved from projectiles to interactions, and secondly, the mean incident momentum using experimental data on the collisions of proton, helium, oxygen, silicon, and sulfur ...

Holographic study of the QCD matter under external conditions
Holographic QCD is based on the AdS/CFT duality and offers new nonperturbative approaches to understand the strongly interacting regime of gauge theories.

Based on the smallest physical constant of the product of space interval, time interval, and energy, the fractal quantum gravity (FQG) theory has demonstrated that every particle or physical system consists of these smallest units in fractal structures ...

Strongly Intensive Observables in the Model with String Fusion †
We calculate the strongly intensive observables for multiplicities in two rapidity windows in the model with independent identical strings taking into account the charge sign of particles.

Theoretical description of nucleons paired correlations of even-even nuclei in the adiabatic three-particle model [PDF]
A hyperspherical adiabatic approach (HAA) has been suggested to find the energy spectrum of even-even atomic nuclei modelled by a spherically symmetric even-even core plus two valence nucleons in the external shell.

Excited States of “Elementary” Particles in Gauge-Higgs Theories [PDF]
We show that the gauge and scalar fields which surround static ions in the Ginzburg-Landau model of superconductivity have a spectrum of excitations which are potentially observable.

The Universe out of an Elementary Particle? [PDF]
We consider a model of an elementary particle as a 2 + 1 dimensional brane evolving in a 3 + 1 dimensional space. Introducing gauge fields that live in the brane as well as normal surface tension can lead to a stable "elementary particle" configuration.

Anisotropic Turbulent Advection of a Passive Vector Field: Effects of the Finite Correlation Time
The turbulent passive advection under the environment (velocity) field with finite correlation time is studied. Inertial-range asymptotic behavior of a vector (e.g., magnetic) field, passively advected by a strongly anisotropic turbulent flow, is ...
