A psychometric evaluation of diffusion basis spectrum imaging indicates altered white matter microstructure consistent with elevated edema in depression

Luisa Kaluza · Anne Kühnel · Ekaterina Kuskova · Kim Studener · y 3 más

An inflammatory subtype of major depressive disorder (MDD) is associated with treatment resistance pointing to an unmet need for adjunctive treatments. To evaluate treatment-related changes in brain inflammation, diffusion basis spectrum imaging (DBSI) is a promising non-radiation-based technique for longitudinal desig...

Global solvability in a higher-dimensional chemotaxis system for alopecia areata: Nonlinear proliferation versus logistic degradation

Tang, Haotian · Zheng, Jiashan

This paper is concerned with the Neumann initial-boundary value problem for the chemotaxis system: $u_t=Δu-χ_1\nabla\cdot(u\nabla w)+w-μ_1u^{r_1}$, $v_t=Δv-χ_2\nabla\cdot(v\nabla w)+w+ruv-μ_2v^{r_2}$, and $w_t=Δw+u+v-w$ in $Ω\times(0,\infty)$, which was initially proposed by Dobreva et al. to describe the dynamics of h...

Deciphering the Property-Activity-Stability Trends of Platinum-Rare Earth Nanoalloys During Fuel Cell Operation from Operando X-ray Diffract

Jakub DRNEC · Carlos CAMPOS-ROLDAN · Raphael CHATTOT (ORCID: 0000-0001-6169-530X) · MERYEM ENNAJI · y 1 más

The use of high energy X-ray diffraction is proposed to investigate operando the property-activity-stability trends and the degradation mechanism and of carbon-supported platinum-rare earth (Pt-RE/C) nanoalloys in real fuel cell operating conditions. These materials receive constant growing attention due to their predi...

Formation and characterization of iron superhydrides FeHx with x = 6 beyond 230 GPa

Angelika ROSA · JOAO ELIAS FIGUEIREDO SOARES RODRIGUES · Gaston GARBARINO · Antoine HILBERER · y 3 más

This follow-up proposal focuses on the characterization of the nature of phase transitions in FeHx compounds (with x = 6 or higher) beyond 230 GPa, that have yet been only predicted theoretically. It also aims to provide insights in the pressure-induced rearrangements of local electronic and atomic structures in these...

Operando investigation of CuFe-based catalysts for higher alcohol synthesis from CO2

Dragos Constantin STOIAN · Elisavet TAZEDAKI · Yuzhen GE · Tangsheng ZOU · y 1 más

In this project, by combining X-ray absorption spectroscopy (XAS) and X-ray powder diffraction (XRD) measurements, we aim to probe the dynamic electronic, structural, and morphological evolution of the active metal and promoter phases in CuFe@ZrO2 catalytic systems used for higher alcohol synthesis from CO2. The unique...

Oxidation states of uranium in single hot particles

Tobias WEISSENBORN · Christoph HENNIG · Laura LEIFERMANN

The aim of the experiment is to clarify the influence of the environmental conditions on the oxidation states of uranium in single ‘hot’ particles. The particles differ in their structure, elemental and isotopic composition. It is known that there are different classes of particles, which differ in the oxidation state....

Using hierarchical Bayesian modelling to assess shedder test suitability

Duncan Taylor · Margot Minck · Adrian Linacre · Roland A.H. van Oorschot · y 1 más

Advances in trace DNA analysis, in combination with increased ability to detect minute amounts of DNA, necessitated research investment into the understanding of the factors relevant to DNA-TPPR, including individuals' ability to deposit their trace DNA, termed their shedder status. Variability in shedder tests and ass...

Subdiffusive fractional limit of a jump-renewal equation

Berry, Hugues · Gabriel, Pierre · Lepoutre, Thomas · Quiblier, Nathan

In this paper, we consider an age-structured jump model that arises as a description of continuous time random walks with infinite mean waiting time between jumps. We prove that under a suitable rescaling, this equation converges in the long time large scale limit to a time fractional subdiffusion equation.

Role of TRPA1 in cortical spreading depression-associated migraine pathophysiology

Jiang, Liwen

Introduction: Migraine is a neurovascular disorder, ranking as the 2nd most prevalent and 6th most disabling disease. The transient receptor potential ankyrin 1 (TRPA1), a cation channel that is sensitive to stress, has been proposed as a potential target for migraine therapy in that the channel activation triggers mec...
