text: 'The classical Birkhoff conjecture claims that the boundary of a strictly
convex integrable billiard table is necessarily an ellipse (or a circle as a special
case). 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.'

with rational caustics is dense. More precisely, the set of billiard boundaries
with caustics of rotation number 1/q is polynomially sense in the smooth case,
and exponentially dense in the analytic case.

text: Chaperonins are ubiquitous protein assemblies present in bacteria, eukaryota,
and archaea, facilitating the folding of proteins, preventing protein aggregation,
and thus participating in maintaining protein homeostasis in the cell. 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.

text: The exchange of metabolites between the mitochondrial matrix and the cytosol
depends on β-barrel channels in the outer membrane and α-helical carrier proteins
in the inner membrane. 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.

text: For any strictly convex planar domain Ω ⊂ R2 with a C∞ boundary one can associate
an infinite sequence of spectral invariants introduced by Marvizi–Merlose [5].
These invariants can generically be determined using the spectrum of the Dirichlet
problem of the Laplace operator. A natural question asks if this collection is
sufficient to determine Ω up to isometry. In this paper we give a counterexample,
namely, we present two nonisometric domains Ω and Ω¯ with the same collection
of Marvizi–Melrose invariants. Moreover, each domain has countably many periodic
orbits {Sn}n≥1 (resp. {S¯n}n⩾1) of period going to infinity such that Sn and S¯n
have the same period and perimeter for each n.

text: The development of strategies to assemble microscopic machines from dissipative
building blocks are essential on the route to novel active materials. 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.

text: The novel electronic state of the canted antiferromagnetic (AFM) insulator,
strontium iridate (Sr2IrO4) has been well described by the spin-orbit-entangled
isospin Jeff = 1/2, but the role of isospin in transport phenomena remains poorly
understood. 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.

text: We report the temperature-dependent resistivity ρ(T) of chalcogenide NiS2-xSex
(x = 0.1) using hydrostatic pressure as a control parameter in the temperature
range of 4–300 K. 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. We analyzed the metallic behavior and proposed Fermi-liquid behavior
of NiS1.9Se0.1.
