Connectivity-Based Parcellation of the Cortical Mantle Using q-Ball Diffusion Imaging

open access: yesInternational Journal of Biomedical Imaging, 2008
This paper exploits the idea that each individual brain region has a specific connection profile to create parcellations of the cortical mantle using MR diffusion imaging. The parcellation is performed in two steps. First, the cortical mantle is split at

Density and current profiles in Uq(A2(1)) zero range process

open access: yesNuclear Physics B, 2017
The stochastic R matrix for Uq(An(1)) introduced recently gives rise to an integrable zero range process of n classes of particles in one dimension.

Bose-Einstein condensation and condensation of $q$-particles in equilibrium and non equilibrium thermodynamics: a new approach

open access: yes, 2015
In the setting of the principle of local equilibrium which asserts that the temperature is a function of the energy levels of the system, we exhibit plenty of steady states describing the condensation of free Bosons which are not in thermal equilibrium.

Particles, Objects, and Physics [PDF]

open access: yes, 2005
This thesis analyses the ontological nature of quantum particles. In it I argue that quantum particles, despite their indistinguishability, are objects in much the same way as classical particles. This similarity provides an important point of continuity

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

open access: yesAdvanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Barrow entropy effects on thermodynamics and quasi-periodic oscillations around a Frolov black hole

open access: yesNuclear Physics B
This study investigates the geometric structure, particle dynamics, and thermal properties of the non-rotating Frolov black hole. We analyze the black hole geometry and derive the effective potential governing the motion of the test particle, showing the

On graphs with exactly three Q-eigenvalues at least two

open access: yes, 2013
For a graph G, we here investigate its signless Laplacian matrix Q(G) and the corresponding Q-eigenvalues. By considering the relation between the Q-spectrum and the circumference of G, we characterize all connected graphs with exactly three Q ...

The Mean Lifetime of V-Particles [PDF]

open access: yes, 1953
A maximum-likelihood procedure for determining mean lifetimes of V-particles from cloud chamber data is discussed and applied to samples taken from a group of 134 neutral V-particle decays.

Rotary 3D Printing With Integrated Electroplating

open access: yesAdvanced Engineering Materials, EarlyView.
A rotary material extrusion platform integrates localized copper electroplating with printing and encapsulation to fabricate cylindrical polymer–metal structures containing fully embedded, low‐resistance conductive pathways that enable internal Joule heating and thermally activated shape‐memory responses.

Search for heavy long-lived multicharged particles in proton-proton collisions at \sqrts = 13 TeV using the ATLAS detector

open access: yes, 2019
A search for heavy long-lived multicharged particles is performed using the ATLAS detector at the LHC. Data with an integrated luminosity of 36.1  fb−1 collected in 2015 and 2016 from proton-proton collisions at √s=13  TeV are examined.
