Detecting (non)parallel evolution in multidimensional spaces
Junya Watanabe
Feb 16, 2022
Parallelism between evolutionary trajectories in a trait space is often seen as evidence for repeatability of phenotypic evolution, and angles between trajectories play a pivotal role in the analysis of parallelism. However...

Exploring Totalitarian Elements of Artificial Intelligence in Higher Education With Hannah Arendt
Alice Watanabe
Jan 01, 2023
From the perspective of political philosophy, this article examines the extent to which artificial intelligence (AI) applications in higher education contain totalitarian elements. Drawing on the theoretical considerations of...

Digital photogrammetry for the documentation of structural damage in earthen archaeological sites
Ajina Tepa is one of the most important archaeological sites in central Asia and it was fully excavated in the 1960s using modern documentation techniques. The UNESCO/Japan Trust Fund project ‘Preservation of the Buddhist...
A Practical Method for Continuous Production of sp3-Rich Compounds from (Hetero)Aryl Halides and Redox-Active Esters.
A practically useful coupling reaction between aromatic halides and redox-active esters was realized by nickel catalysis through the use of a packed zinc bed column in continuous flow. Multiple reuse of the column showed a...

Wing Musculature Reconstruction in Extinct Flightless Auks (<i>Pinguinus</i> and <i>Mancalla</i>) Reveals Incomplete Convergence with Penguins (Spheniscidae) Due to Differing Ancestral States.
Despite longstanding interest in convergent evolution, factors that result in deviations from fully convergent phenotypes remain poorly understood. In birds, the evolution of flightless wing-propelled diving has emerged as a...
Communicating Identity Then and Now: A Comparative Content Analysis of Writings by College Students During Times of Political Unrest

Focused Representation of Successive Task Episodes in Frontal and Parietal Cortex.
Complex cognition is dynamic, with each stage of a task requiring new cognitive processes appropriately linked to stimulus or other content. To investigate control over successive task stages, we recorded neural activity in...

Preservation of earthen sites in remote areas
The Buddhist monastery of Ajina Tepa is one of the most significant in Central Asia as it was fully excavated using up-to-date archaeological methods and was extensively documented. The site is a sophisticated blend of earthen...

Simulations and spectra of water in CO matrices.
Rafael Escribano, Emilio Artacho, Akira Kouchi, Tetusya Hama, Yuki Kimura, Hiroshi Hidaka, Naoki Watanabe
Aug 17, 2017
Models for the inclusion of water molecules in carbon monoxide matrices are developed using density functional theory applied to amorphous solid systems. The models cover a large range of systems for smaller or larger CO...
Cleaning interfaces in layered materials heterostructures.
Heterostructures formed by stacking layered materials require atomically clean interfaces. However, contaminants are usually trapped between the layers, aggregating into randomly located blisters, incompatible with scalable...

Tunable Fermi surface topology and Lifshitz transition in bilayer graphene
Anastasia Varlet, Marcin Mucha-Kruczynski, Dominik Bischoff, Pauline Simonet, Takashi Taniguchi, Kenji Watanabe, Vladimir Fal'ko, Thomas Ihn, Klaus Ensslin
Dec 01, 2015
Bilayer graphene is a highly tunable material: not only can one tune the Fermi energy using standard gates, as in single-layer graphene, but the band structure can also be modified by external perturbations such as transverse...
Anomalous sequence of quantum hall liquids revealing a tunable Lifshitz transition in bilayer graphene
Anastasia Varlet, Dominik Bischoff, Pauline Simonet, Kenji Watanabe, Takashi Taniguchi, Thomas Ihn, Klaus Ensslin, Marcin Mucha-Kruczynski, Vladimir I. Fal’ko
Sep 12, 2014
Bilayer graphene is a unique system where both the Fermi energy and the low-energy electron dispersion can be tuned. This is brought about by an interplay between trigonal warping and the band gap opened by a transverse electric...
Direct observation of ultrafast singlet exciton fission in three dimensions.
Arjun Ashoka, Nicolas Gauriot, Aswathy V Girija, Nipun Sawhney, Alexander J Sneyd, Kenji Watanabe, Takashi Taniguchi, Jooyoung Sung, Christoph Schnedermann, Akshay Rao
Nov 15, 2022
We present quantitative ultrafast interferometric pump-probe microscopy capable of tracking of photoexcitations with sub-10 nm spatial precision in three dimensions with 15 fs temporal resolution, through retrieval of the full...

Apr 28, 2020
Relative brain sizes in birds can rival those of primates, but large-scale patterns and drivers of avian brain evolution remain elusive. Here, we explore the evolution of the fundamental brain-body scaling relationship across...
Sidechain Diversification of Grandifloracin Allows Identification of Analogues with Enhanced Anti-Austerity Activity against Human PANC-1 Pancreatic Cancer Cells
Benjamin E. Alexander, Sijia Sun, Matthew J. Palframan, Gabriele Kociok-Köhn, Dya Fita Dibwe, Shiro Watanabe, Lorenzo Caggiano, Suresh Awale, Simon E. Lewis
Jan 07, 2020
The natural product (+)-grandifloracin is a potent “anti-austerity” agent, able to suppress the ability of various pancreatic cancer cell lines to tolerate conditions of nutrient deprivation. Such anti-austerity agents...
