On the Birman exact sequence of the subgroups of the mapping class group of genus three

Ma Luo · Tatsunari Watanabe

We prove that for any finite index subgroup of the mapping class group containing the Johnson subgroup, the profinite Birman exact sequence does not split in genus $g\ge 3$, extending prior results of Hain and the second author for $g\ge 4$. For the Torelli group, we prove that the graded Lie algebra version of the Bir...

Linking cellular metabolism to mitochondrial outer membrane potential

Kaitlin, Abrantes · Bethel G, Beyene · Nina A, Bautista · Wendy, Fitzgerald · y 3 más

The voltage-dependent anion channel (VDAC) of the mitochondrial outer membrane (MOM) responds to transmembrane voltage through intrinsic gating and voltage-dependent interactions with cytosolic proteins, such as α-synuclein and β-tubulin. Despite this characteristic voltage sensitivity found in vitro, the existence of...

Mutual visibility in Moore graphs and (d,2)-graphs with defect

Tonny K. B · Shikhi M

The concept of mutual visibility in a graph encodes combinatorial information about vertex subsets with prescribed visibility properties and serves as a useful algebraic invariant. In this paper, we derive algebraic conditions for the mutual-visibility number of $(d,2)$-graphs with non-negative defect. We then determin...

Speckle based Dark field Imaging to map saxs signal

Clara MAGNIN · Ludovic BROCHE

Speckle base imaging allows to quantify x-ray scattering by analyzing speckle defocus magnitude and direction. This analysis can be repeated at different x-ray propagation distances to retrieve the full saxs curve while keeping the macro-structure information from the regular imaging. We intend to scan small glass sphe...

In situ effect of printing parameters on microstructural anisotropy of bioink based hydrogel during micro-extrusion bioprinting process for

Anatole MORCOS · Laurent DAVID · Gilbert CHAHINE · Isabelle MORFIN · y 2 más

Bioprinting is a promising process to provide hospitals with tissue substitutes mimicking any organ without having to resort to donors. During bioprinting, a cell-encapsulating hydrogel, also known as bioink, is deposited layer by layer to ultimately develop a tissue substitute. An alginate/gelatine/fibrinogen hydrogel...

Exploring the dynamic nature of OCP crystals by combined use of diffraction and in crystallo spectrophotometry at room-temperature

Sylvain ENGILBERGE · Antoine ROYANT · Jacques-Philippe COLLETIER · Jana TARAF · y 1 más

The photoactive Orange Carotenoid Protein (OCP) is a reversible photoswitch which serves photoprotection in cyanobacteria (Wilson et al. 2006). OCP is functionalized by a keto-carotenoid pigment which, in the presence of a blue-green photon, is able to induce conformational changes resulting in a photoactivated state c...

Operando characterisation of solid-state batteries with multi-mode X-ray imaging

Matt WILSON · Guanting LI · Kaiyi WANG · Abeiram SIVARAJAH · y 7 más

Solid-state lithium metal batteries (SSLMBs) are safer to operate as they use a solid-state electrolyte to replace conventional flammable liquid electrolyte. However, SSLMBs suffer from faster degradation over charge and discharge cycles compared with conventional lithium ion batteries. The changes of material chemical...

A decomposition method for finite-time stabilization of bilinear systems with applications to parabolic and hyperbolic equations

Fenza, Kamal · Labbadi, Moussa · Ouzahra, Mohamed

In this work, we address the problem of finite-time stabilization for a class of bilinear system. We propose a decomposition-based approach in which the nominal system is split into two subsystems, one of which is inherently finite-time stable without control. This allows the stabilization analysis to focus solely on t...

Ischemic stroke remains a leading cause of disability, despite increasing patient eligibility for undergoing vessel recanalization. Ischemia/reperfusion injury (I/RI), the inflammatory cascade triggered by ischemia and subsequent reperfusion, contributes to infarct evolution and functional outcomes. However, investigat...

X-ray Magneto Chiral Dichroism and its angular dependence in chiral crystals at Co K-edge

Nathan YUTRONKIE · Elizabeth HILLARD · Andrei ROGALEV · Philippe SAINCTAVIT · y 4 más

Though predicted in the 1960s, Magneto Chiral Dichroism (MD) has been observed several decades latter and almost exclusively in the UV-visible range. Some of us recently published a validation of the microscopic theory behind magnetochiral dichroism in the UV-visible range, based on experimental observations on chiral...
