Ultrafast Formation of a Photoinduced Hidden State Driven by a Bond-Order Wave in a Metal-Organic Framework

Samiran Banu, T. Amano, Takahisa Kato, Kou Takubo et autres

Sub-10-fs pump-probe reflectivity measurements combined with model calculations reveal the emergence of a photoinduced hidden (PH) state in a donor-acceptor-type metal-organic framework. Transient spectra exhibit an additional absorption band developing on a ≈30 fs timescale, signaling the ultrafast formation of the PH …

Photoinduced electronic ferroelectric phase in a metal-organic framework

Takahisa Kato, Shu Ohmura, Akira Takahashi

We investigate the physical properties and lattice relaxation of important photoexcited states in a charge-transfer-type metal-organic framework ( NPr 4 ) 2 [ Fe 2 ( Cl 2 An ) 3 ] . We construct the one-dimensional spinless fermion model for the …

The phase II study of pembrolizumab plus lenvatinib for patients with unresectable cutaneous angiosarcoma (Pembro-Lenva for cAS/PLAS trial).

Dai Ogata, Eiji Nakano, Takeru Funakoshi, Akira Takahashi et autres

TPS11586 Background: Cutaneous angiosarcoma (cAS) is a rare cancer that often occurs in elderly people with common recurrence and metastasis after surgery. Chemotherapy, radiation therapy, and their combination are widely used, but their effectiveness is insufficient. With the increasing number of cAS …

Ringtail: Practical Two-Round Threshold Signatures from Learning with Errors

Cecilia Boschini, Darya Kaviani, Russell W. F. Lai, Giulio Malavolta et autres

A threshold signature scheme splits the signing key among$\ell$parties, such that any$t$-subset of parties can jointly generate signatures on a given message. Designing concretely efficient post-quantum threshold signatures is a pressing question, as evidenced by NIST's recent call. In this work, we …

Inhomogeneous reduction-annealing effects on the electron-doped cuprate superconductor revealed by micro-focused angle-resolved photoemission spectroscopy

M. Miyamoto, Masafumi Horio, Kei Moriya, Akira Takahashi et autres

The development of the protect-annealing method has extended the superconductivity of the electron-doped cuprate Pr$_{1.3-x}$La$_{0.7}$Ce$_{x}$CuO$_{4}$ (PLCCO) into lower Ce concentrations, while the superconducting volume fraction decreases with underdoping. Employing angle-resolved photoemission spectroscopy with a micro-focused beam, we investigated the electronic structure of …

Extraction of important degrees of freedom in quantum dynamics using singular value decomposition: Application to linear optical spectrum in two-dimensional Mott insulators

Jun Tokimoto, Shu Ohmura, Akira Takahashi, Kaoru Iwano et autres

We propose a new approach to extract the important degrees of freedom in quantum dynamics induced by an external stimulus. We calculate the coefficient matrix numerically, where the $i\ensuremath{-}l$ element of the matrix is the coefficient of the $l\mathrm{th}$ basis state at …

Characterization of Outer Membrane Vesicles Produced by Vibrio vulnificus

Ryo Higashiyama, Yuna Kanda, Takaaki Shimohata, Kai Ishida et autres

Vibrio vulnificus (V. vulnificus) is a halophilic gram-negative bacterium that inhabits coastal warm water and induce severe diseases such as primary septicemia. To investigate the mechanisms of rapid bacterial translocation on intestinal infection, we focused on outer membrane vesicles (OMVs), which are …
