In this article we prove a complete local version of this conjecture: a small integrable perturbation of an ellipse must be an ellipse. This extends and completes the result in Avila-De Simoi-Kaloshin, where nearly circular domains were considered. One of the crucial ideas in the proof is to extend action-angle coordinates for elliptic billiards into complex domains (with respect to the angle), and to thoroughly analyze the nature of their complex singularities. As an application, we are able to prove some spectral rigidity results for elliptic domains.' article_processing_charge: No article_type: original author: - first_name: Vadim full_name: Kaloshin, Vadim id: FE553552-CDE8-11E9-B324-C0EBE5697425 last_name: Kaloshin orcid: 0000-0002-6051-2628 - first_name: Alfonso full_name: Sorrentino, Alfonso last_name: Sorrentino citation: ama: Kaloshin V, Sorrentino A.

During their functional cycle, they bind unfolded client proteins inside their double ring structure and promote protein folding by closing the ring chamber in an adenosine 5′-triphosphate (ATP)–dependent manner. Although the static structures of fully open and closed forms of chaperonins were solved by x-ray crystallography or electron microscopy, elucidating the mechanisms of such ATP-driven molecular events requires studying the proteins at the structural level under working conditions. We introduce an approach that combines site-specific nuclear magnetic resonance observation of very large proteins, enabled by advanced isotope labeling methods, with an in situ ATP regeneration system. Using this method, we provide functional insight into the 1-MDa large hsp60 chaperonin while processing client proteins and reveal how nucleotide binding, hydrolysis, and release control switching between closed and open states. While the open conformation stabilizes the unfolded state of client proteins, the internalization of the client protein inside the chaperonin cavity speeds up its functional cycle. This approach opens new perspectives to study structures and mechanisms of various ATP-driven biological machineries in the heat of action. article_number: eaau4196 article_processing_charge: No article_type: original author: - first_name: Guillaume full_name: Mas, Guillaume last_name: Mas - first_name: Jia-Ying full_name: Guan, Jia-Ying last_name: Guan - first_name: Elodie full_name: Crublet, Elodie last_name: Crublet - first_name: Elisa Colas full_name: Debled, Elisa Colas last_name: Debled - first_name: Christine full_name: Moriscot, Christine last_name: Moriscot - first_name: Pierre full_name: Gans, Pierre last_name: Gans - first_name: Guy full_name: Schoehn, Guy last_name: Schoehn - first_name: Pavel full_name: Macek, Pavel last_name: Macek - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 - first_name: Jerome full_name: Boisbouvier, Jerome last_name: Boisbouvier citation: ama: Mas G, Guan J-Y, Crublet E, et al.

The essential translocase of the inner membrane (TIM) chaperones escort these proteins through the intermembrane space, but the structural and mechanistic details remain elusive. We have used an integrated structural biology approach to reveal the functional principle of TIM chaperones. Multiple clamp-like binding sites hold the mitochondrial membrane proteins in a translocation-competent elongated form, thus mimicking characteristics of co-translational membrane insertion. The bound preprotein undergoes conformational dynamics within the chaperone binding clefts, pointing to a multitude of dynamic local binding events. Mutations in these binding sites cause cell death or growth defects associated with impairment of carrier and β-barrel protein biogenesis. Our work reveals how a single mitochondrial “transfer-chaperone” system is able to guide α-helical and β-barrel membrane proteins in a “nascent chain-like” conformation through a ribosome-free compartment. article_processing_charge: No article_type: original author: - first_name: Katharina full_name: Weinhäupl, Katharina last_name: Weinhäupl - first_name: Caroline full_name: Lindau, Caroline last_name: Lindau - first_name: Audrey full_name: Hessel, Audrey last_name: Hessel - first_name: Yong full_name: Wang, Yong last_name: Wang - first_name: Conny full_name: Schütze, Conny last_name: Schütze - first_name: Tobias full_name: Jores, Tobias last_name: Jores - first_name: Laura full_name: Melchionda, Laura last_name: Melchionda - first_name: Birgit full_name: Schönfisch, Birgit last_name: Schönfisch - first_name: Hubert full_name: Kalbacher, Hubert last_name: Kalbacher - first_name: Beate full_name: Bersch, Beate last_name: Bersch - first_name: Doron full_name: Rapaport, Doron last_name: Rapaport - first_name: Martha full_name: Brennich, Martha last_name: Brennich - first_name: Kresten full_name: Lindorff-Larsen, Kresten last_name: Lindorff-Larsen - first_name: Nils full_name: Wiedemann, Nils last_name: Wiedemann - first_name: Paul full_name: Schanda, Paul id: 7B541462-FAF6-11E9-A490-E8DFE5697425 last_name: Schanda orcid: 0000-0002-9350-7606 citation: ama: Weinhäupl K, Lindau C, Hessel A, et al.

We recently demonstrated the hierarchical self-assembly of phoretic microswimmers into self-spinning microgears and their synchronization by diffusiophoretic interactions [Aubret et al., Nat. Phys., 2018]. In this paper, we adopt a pedagogical approach and expose our strategy to control self-assembly and build machines using phoretic phenomena. We notably introduce Highly Inclined Laminated Optical sheets microscopy (HILO) to image and characterize anisotropic and dynamic diffusiophoretic interactions, which cannot be performed by conventional fluorescence microscopy. The dynamics of a (haematite) photocatalytic material immersed in (hydrogen peroxide) fuel under various illumination patterns is first described and quantitatively rationalized by a model of diffusiophoresis, the migration of a colloidal particle in a concentration gradient. It is further exploited to design phototactic microswimmers that direct towards the high intensity of light, as a result of the reorientation of the haematite in a light gradient. We finally show the assembly of self-spinning microgears from colloidal microswimmers and carefully characterize the interactions using HILO techniques. The results are compared with analytical and numerical predictions and agree quantitatively, stressing the important role played by concentration gradients induced by chemical activity to control and design interactions. Because the approach described hereby is generic, this works paves the way for the rational design of machines by controlling phoretic phenomena. article_processing_charge: No article_type: original author: - first_name: Antoine full_name: Aubret, Antoine last_name: Aubret - first_name: Jérémie A full_name: Palacci, Jérémie A id: 8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d last_name: Palacci orcid: 0000-0002-7253-9465 citation: ama: Aubret A, Palacci JA.

In this study, antiferromagnet-based spintronic functionality is demonstrated by combining unique characteristics of the isospin state in Sr2IrO4. Based on magnetic and transport measurements, large and highly anisotropic magnetoresistance (AMR) is obtained by manipulating the antiferromagnetic isospin domains. First-principles calculations suggest that electrons whose isospin directions are strongly coupled to in-plane net magnetic moment encounter the isospin mismatch when moving across antiferromagnetic domain boundaries, which generates a high resistance state. By rotating a magnetic field that aligns in-plane net moments and removes domain boundaries, the macroscopically-ordered isospins govern dynamic transport through the system, which leads to the extremely angle-sensitive AMR. As with this work that establishes a link between isospins and magnetotransport in strongly spin-orbit-coupled AFM Sr2IrO4, the peculiar AMR effect provides a beneficial foundation for fundamental and applied research on AFM spintronics. article_number: '1805564' article_processing_charge: No article_type: original author: - first_name: Nara full_name: Lee, Nara last_name: Lee - first_name: Eunjung full_name: Ko, Eunjung last_name: Ko - first_name: Hwan Young full_name: Choi, Hwan Young last_name: Choi - first_name: Yun Jeong full_name: Hong, Yun Jeong last_name: Hong - first_name: Muhammad full_name: Nauman, Muhammad id: 32c21954-2022-11eb-9d5f-af9f93c24e71 last_name: Nauman orcid: 0000-0002-2111-4846 - first_name: Woun full_name: Kang, Woun last_name: Kang - first_name: Hyoung Joon full_name: Choi, Hyoung Joon last_name: Choi - first_name: Young Jai full_name: Choi, Young Jai last_name: Choi - first_name: Younjung full_name: Jo, Younjung last_name: Jo citation: ama: Lee N, Ko E, Choi HY, et al.

The insulating behavior of ρ(T) survives at low temperatures in the pressure regime below 7.5 kbar, whereas a clear insulator-to-metallic transition is observed above 7.5 kbar. Two types of magnetic transitions, from the paramagnetic (PM) to the antiferromagnetic (AFM) state and from the AFM state to the weak ferromagnetic (WF) state, were evaluated and confirmed by magnetization measurement. According to the temperature–pressure phase diagram, the WF phase survives up to 7.5 kbar, and the transition temperature of the WF transition decreases as the pressure increases, whereas the metal–insulator transition temperature increases up to 9.4 kbar.
