This talk was part of the of the online workshop on "Interdisciplinary Challenges in Nonequilibrium Physics" held April 12 - 16, 2021. Discontinuities within orientational fields configure topological defects [1]. They are often present in materials featuring orientational, nematic, order, and can be found in very diverse areas, which span a vast range of length scales [2]. Interestingly, in active nematic systems, topological defects imply not only strong orientational gradients but also well-defined flow and stress patterns in very localized regions [3]. Recent works have shown the influence of these defects in determining the dynamics of living systems, from cell monolayers [4–6] to simple organisms [7]. Here, we study how nematic monolayers composed of muscle cells self-organize and evolve under circular confinement, which enforces a topological charge S=+1. Under strong confinements, with size competing with the characteristic nematic correlation length, the formation of half-integer defects (s=±1/2) is hampered, resulting in spontaneous cellular arrangements with one single integer defect (s=+1) at the center of the islands, namely, rotating spirals and quasi-static asters [8]. These singularities imply distinct mechanical fields, which lead, eventually, to the localized expression of muscle-specific proteins and the formation of 3D nematic cellular protrusions [9]. [1] P.

往年のヴィルトゥオーゾの真髄を受け継ぐバイオリニスト 久保陽子さん。今なお現在進行形で続く彼女の飽くなき「挑戦」とそれを可能にするエネルギーの秘密に迫ります。 We hear about Yoko Kubo’s relentless energy and insatiable appetite for a challenge - and how she inherited the essence of former Virtuosi. MUSIC Credits: Haydn string quartet op.64 no 5 "The Lark" - the 4th movement performed by Archet Quartet (1st Vn Yoko Kubo, 2nd Vn Takako Watanabe, Va Sakura Kawaguchi, Vc Gen Yokosaka) Violin Sonata by Tomojiro Ikenouch performed by Yoko Kubo Bach's "Chaconne" performed by Yoko Kubo 【BG Films】 文京楽器のミッション「すべてはプレイヤーの喜びのために」を体現する短編映像集「BG Films」。英国人写真家ダニエル・レイン氏を映像監督に迎え、バイオリニスト久保陽子さんへのロングインタビューや演奏会密着、弓職人大瀬国隆を訪ねて富山・五箇山ロケを敢行。貴重なエクスペリエンスを美しい4K画像で収録しました。 (http•••) BG Films is a collection of short documentary films embodying the mission of Bunkyo Gakki, which is "All for Musicians Delight". We invited British photographer Daniel Lane to Japan as the director. We were able to collect valuable experiences in beautiful 4K images. The films show what’s behind the music, how skilled craftspeople and musicians come together to work symbiotically. Within the collection is an interview with violinist Yoko Kubo - alongside intimate shots of her performing; we visit Gokayama, a UNESCO world-heritage site to meet renowned bow maker Ohse Kunitaka; and we see violin maker Yuki Hori at work in his workshop.
