Motion Capture Dataset for Practical Use of AI-based Motion Editing and Stylization
In this work, we proposed a new style-diverse dataset for the domain of
motion style transfer. The motion dataset uses an industrial-standard human
bone structure and thus is industry-ready to be plugged into 3D characters for
many projects. We claim the challenges in motion style transfer and encourage
future work in this domain by releasing the proposed motion dataset both to the
public and the market. We conduct a comprehensive study on motion style
transfer in the experiment using the state-of-the-art method, and the results
show the proposed dataset's validity for the motion style transfer task
Non-local spin correlation as a signature of Ising anyons trapped in vacancies of the Kitaev spin liquid
In the Kitaev chiral spin liquid, Ising anyons are realized as Majorana zero
modes bound in fluxes, which, however, are thermal excitations with
finite decay rates. On the other hand, a lattice vacancy traps a flux
even in the ground state, resulting in the stable realization of a Majorana
zero mode in the flux. We demonstrate that spin-spin correlation
functions between two vacancy sites exhibit long-range correlation arising from
the fractionalized character of Majorana zero modes, in spite of the strong
decay of bulk spin correlations. Remarkably, this non-local spin correlation
does not decrease as the distance between two vacancy sites increases,
signaling teleportation of Majorana zero modes. Furthermore, we clarify that
the non-local correlation can be detected electrically via the measurement of
non-local conductance between two vacancy sites, which is also utilized for the
readout of Majorana qubits. These findings pave the way to the
measurement-based quantum computation with Ising anyons trapped in vacancies of
the Kitaev spin liquid.Comment: 6 pages + 4 figures, and a Supplemental Materia
Curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1, 6-heptadiene-3,5-dione) Blocks the Chemotaxis of Neutrophils by Inhibiting Signal Transduction through IL-8 Receptors
We investigated the impact of curcumin on neutrophils. Chemotactic activity via human recombinant IL-8 (hrIL-8) was significantly inhibited by curcumin. Curcumin reduced calcium ion flow induced by internalization of the IL-8 receptor. We analyzed flow cytometry to evaluate the status of the IL-8 receptor after curcumin treatment. The change in the distribution of receptors intracellularly and on the cell surface suggested that curcumin may affect the receptor trafficking pathway intracellulary.
Rab11 is a low molecular weight G protein associated with the CXCR recycling pathway. Following curcumin treatment, immunoprecipitation studies showed that the IL-8 receptor was associated with larger amounts of active Rab11 than that in control cells. These data suggest that curcumin induces the stacking of the Rab11 vesicle complex with CXCR1 and CXCR2 in the endocytic pathway. The mechanism for antiinflammatory response by curcumin may involve unique regulation of the Rab11 trafficking molecule in recycling of IL-8 receptors
De novo vertebral artery dissecting aneurysm after internal trapping of the contralateral vertebral artery
We present the case of a de novo vertebral artery dissecting aneurysm (VADA) after endovascular trapping of a ruptured VADA on the contralateral side. The first ruptured VADA involved the posterior inferior cerebellar artery, which was successfully treated by endovascular internal trapping using a stent. A follow-up study at 3 months revealed a de novo VADA on the contralateral side. The second VADA was successfully embolized using coils while normal arterial flow in the vertebral artery was preserved using a stent. Increased hemodynamic stress may cause the development of a de novo VADA on the contralateral side
