The resulting trajectories are usually consistent with some type of anomalous diffusion, but the molecular origins behind the observed anomalous behaviour are usually not obvious. Here we use coarse-grained molecular dynamics simulations to help identify the physical mechanisms that can give rise to experimentally observed trajectories of nanoscopic objects moving on biological membranes. We find that diffusion on membranes of high fluidities typically results in normal diffusion of the adsorbed nanoparticle, irrespective of the concentration of receptors, receptor clustering, or multivalent interactions between the particle and membrane receptors. Gel-like membranes on the other hand result in anomalous diffusion of the particle, which becomes more pronounced at higher receptor concentrations. This anomalous diffusion is characterised by local particle trapping in the regions of high receptor concentrations and fast hopping between such regions. The normal diffusion is recovered in the limit where the gel membrane is saturated with receptors. We conclude that hindered receptor diffusivity can be a common reason behind the observed anomalous diffusion of viruses, vesicles, and nanoparticles adsorbed on cell and model membranes. Our results enable direct comparison with experiments and offer a new route for interpreting motility experiments on cell membranes."}],"acknowledgement":"We thank Jessica McQuade for her input at the start of the project.

Cryo-EM and NMR spectroscopy both provide structural information, but currently cryo-EM does not routinely give access to atomic-level structural data, and, generally, NMR structure determination is restricted to small (<30 kDa) proteins. We introduce an integrated structure determination approach that simultaneously uses NMR and EM data to overcome the limits of each of these methods. The approach enables structure determination of the 468 kDa large dodecameric aminopeptidase TET2 to a precision and accuracy below 1 Å by combining secondary-structure information obtained from near-complete magic-angle-spinning NMR assignments of the 39 kDa-large subunits, distance restraints from backbone amides and ILV methyl groups, and a 4.1 Å resolution EM map. The resulting structure exceeds current standards of NMR and EM structure determination in terms of molecular weight and precision. Importantly, the approach is successful even in cases where only medium-resolution cryo-EM data are available.","lang":"eng"}],"citation":{"ista":"Gauto DF, Estrozi LF, Schwieters CD, Effantin G, Macek P, Sounier R, Sivertsen AC, Schmidt E, Kerfah R, Mas G, Colletier J-P, Güntert P, Favier A, Schoehn G, Schanda P, Boisbouvier J. 2019.

In magic‐angle‐spinning (MAS) NMR, μs dynamics can be visualized by R1p rotating‐frame relaxation dispersion experiments in different regimes of radio‐frequency field strengths: at low RF field strength, isotropic‐chemical‐shift fluctuation leads to “Bloch‐McConnell‐type” relaxation dispersion, while when the RF field approaches rotary resonance conditions bond angle fluctuations manifest as increased R1p rate constants (“Near‐Rotary‐Resonance Relaxation Dispersion”, NERRD). Here we explore the joint analysis of both regimes to gain comprehensive insight into motion in terms of geometric amplitudes, chemical‐shift changes, populations and exchange kinetics. We use a numerical simulation procedure to illustrate these effects and the potential of extracting exchange parameters, and apply the methodology to the study of a previously described conformational exchange process in microcrystalline ubiquitin."}],"volume":20,"extern":"1","publication":"ChemPhysChem","oa_version":"Submitted Version","month":"01","keyword":["Physical and Theoretical Chemistry","Atomic and Molecular Physics","and Optics"],"language":[{"iso":"eng"}],"type":"journal_article","date_published":"2019-01-21T00:00:00Z","publication_identifier":{"issn":["1439-4235"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public"},{"publication":"ChemPhysChem","month":"01","oa_version":"Submitted Version","keyword":["Physical and Theoretical Chemistry","Atomic and Molecular Physics","and Optics"],"language":[{"iso":"eng"}],"type":"journal_article","date_published":"2019-01-21T00:00:00Z","publication_identifier":{"issn":["1439-4235"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","issue":"2","author":[{"first_name":"Matthew D.","last_name":"Shannon","full_name":"Shannon, Matthew D."},{"last_name":"Theint","first_name":"Theint","full_name":"Theint, Theint"},{"last_name":"Mukhopadhyay","first_name":"Dwaipayan","full_name":"Mukhopadhyay, Dwaipayan"},{"last_name":"Surewicz","first_name":"Krystyna","full_name":"Surewicz, Krystyna"},{"full_name":"Surewicz, Witold K.","last_name":"Surewicz","first_name":"Witold K."},{"full_name":"Marion, Dominique","last_name":"Marion","first_name":"Dominique"},{"full_name":"Schanda, Paul","orcid":"0000-0002-9350-7606","last_name":"Schanda","first_name":"Paul","id":"7B541462-FAF6-11E9-A490-E8DFE5697425"},{"last_name":"Jaroniec","first_name":"Christopher P.","full_name":"Jaroniec, Christopher P."}],"_id":"8412","pmid":1,"intvolume":"        20","title":"Conformational dynamics in the core of human Y145Stop prion protein amyloid probed by relaxation dispersion NMR","article_processing_charge":"No","date_created":"2020-09-17T10:29:43Z","publication_status":"published","quality_controlled":"1","page":"311-317","article_type":"original","publisher":"Wiley","external_id":{"pmid":["30276945"]},"year":"2019","citation":{"chicago":"Shannon, Matthew D., Theint Theint, Dwaipayan Mukhopadhyay, Krystyna Surewicz, Witold K.

Numerical simulations enabled the experimental relaxation dispersion profiles for most of the fibril core residues to be modelled by using a two‐state exchange process with a common exchange rate of 1000 s−1, corresponding to protein backbone motion on the timescale of 1 ms, and an excited‐state population of 2 %.

For example, electron solids may prevail close to integer filling of the Landau levels before giving way to fractional quantum Hall liquids at higher carrier density1,2. Here, we report the observation of an electron solid with non-collinear spin texture in monolayer graphene, consistent with solidification of skyrmions3—topological spin textures characterized by quantized electrical charge4,5. We probe the spin texture of the solids using a modified Corbino geometry that allows ferromagnetic magnons to be launched and detected6,7. We find that magnon transport is highly efficient when one Landau level is filled (ν=1), consistent with quantum Hall ferromagnetic spin polarization. However, even minimal doping immediately quenches the magnon signal while leaving the vanishing low-temperature charge conductivity unchanged. Our results can be understood by the formation of a solid of charged skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay. Data near fractional fillings show evidence of several fractional skyrmion solids, suggesting that graphene hosts a highly tunable landscape of coupled spin and charge orders."}],"day":"16","doi":"10.1038/s41567-019-0729-8","extern":"1","acknowledgement":"We acknowledge discussions with B.

For twist angles near θ ≈ 1.1°, the low-energy electronic structure of twisted bilayer graphene features isolated bands with a flat dispersion1,2. Recent experiments have observed a variety of low-temperature phases that appear to be driven by electron interactions, including insulating states, superconductivity and magnetism3,4,5,6. Here we report electrical transport measurements up to room temperature for twist angles varying between 0.75° and 2°. We find that the resistivity, ρ, scales linearly with temperature, T, over a wide range of T before falling again owing to interband activation. The T-linear response is much larger than observed in monolayer graphene for all measured devices, and in particular increases by more than three orders of magnitude in the range where the flat band exists. Our results point to the dominant role of electron–phonon scattering in twisted bilayer graphene, with possible implications for the origin of the observed superconductivity.","lang":"eng"}],"quality_controlled":"1","page":"1011-1016","publisher":"Springer Nature","article_type":"original","scopus_import":"1","_id":"10621","issue":"10","author":[{"id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48","full_name":"Polshyn, Hryhoriy","orcid":"0000-0001-8223-8896","last_name":"Polshyn","first_name":"Hryhoriy"},{"full_name":"Yankowitz, Matthew","first_name":"Matthew","last_name":"Yankowitz"},{"full_name":"Chen, Shaowen","first_name":"Shaowen","last_name":"Chen"},{"last_name":"Zhang","first_name":"Yuxuan","full_name":"Zhang, Yuxuan"},{"full_name":"Watanabe, K.","first_name":"K.","last_name":"Watanabe"},{"first_name":"T.","last_name":"Taniguchi","full_name":"Taniguchi, T."},{"full_name":"Dean, Cory R.","last_name":"Dean","first_name":"Cory R."},{"full_name":"Young, Andrea F.","first_name":"Andrea F.","last_name":"Young"}],"article_processing_charge":"No","date_created":"2022-01-13T15:00:58Z","publication_status":"published","intvolume":"        15","title":"Large linear-in-temperature resistivity in twisted bilayer graphene"},{"abstract":[{"lang":"eng","text":"We demonstrate a method for manipulating small ensembles of vortices in multiply connected superconducting structures.

Moving the tip to a particular location in the map stabilizes a distinct multivortex configuration. Thus, the scanning of the tip over a particular trajectory in space permits nontrivial operations to be performed, such as braiding of individual vortices within a larger vortex ensemble—a key capability required by many proposals for topological quantum computing."}],"day":"27","arxiv":1,"doi":"10.1021/acs.nanolett.9b01983","external_id":{"arxiv":["1905.06303"],"pmid":["31246034"]},"citation":{"apa":"Polshyn, H., Naibert, T., &#38; Budakian, R.

The aim of this paper is to show the existence of orbits whose angular momentum performs arbitrary excursions in a large region. In particular, there exist diffusive orbits, that is, with a large variation of angular momentum. The leading idea of the proof consists in analyzing parabolic motions of the comet. By a well-known result of McGehee, the union of future (resp. past) parabolic orbits is an analytic manifold P+ (resp. P−). In a properly chosen coordinate system these manifolds are stable (resp. unstable) manifolds of a manifold at infinity P∞, which we call the manifold at parabolic infinity. On P∞ it is possible to define two scattering maps, which contain the map structure of the homoclinic trajectories to it, i.e. orbits parabolic both in the future and the past. Since the inner dynamics inside P∞ is trivial, two different scattering maps are used. The combination of these two scattering maps permits the design of the desired diffusive pseudo-orbits. Using shadowing techniques and these pseudo orbits we show the existence of true trajectories of the RPETBP whose angular momentum varies in any predetermined fashion."}],"quality_controlled":"1","page":"1173-1228","keyword":["Mathematical Physics","Statistical and Nonlinear Physics"],"language":[{"iso":"eng"}],"publisher":"Springer Nature","article_type":"original","publication":"Communications in Mathematical Physics","_id":"8417","issue":"3","author":[{"first_name":"Amadeu","last_name":"Delshams","full_name":"Delshams, Amadeu"},{"id":"FE553552-CDE8-11E9-B324-C0EBE5697425","last_name":"Kaloshin","first_name":"Vadim","full_name":"Kaloshin, Vadim","orcid":"0000-0002-6051-2628"},{"last_name":"de la Rosa","first_name":"Abraham","full_name":"de la Rosa, Abraham"},{"full_name":"Seara, Tere M.","first_name":"Tere M.","last_name":"Seara"}],"date_created":"2020-09-17T10:41:43Z","article_processing_charge":"No","oa_version":"None","publication_status":"published","intvolume":"       366","month":"09","title":"Global instability in the restricted planar elliptic three body problem"},{"quality_controlled":"1","keyword":["General Engineering","General Physics and Astronomy","General Mathematics"],"language":[{"iso":"eng"}],"publisher":"The Royal Society","article_type":"original","publication":"Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences","_id":"8419","issue":"2131","author":[{"id":"FE553552-CDE8-11E9-B324-C0EBE5697425","full_name":"Kaloshin, Vadim","orcid":"0000-0002-6051-2628","last_name":"Kaloshin","first_name":"Vadim"},{"first_name":"Alfonso","last_name":"Sorrentino","full_name":"Sorrentino, Alfonso"}],"article_processing_charge":"No","date_created":"2020-09-17T10:42:01Z","publication_status":"published","oa_version":"None","intvolume":"       376","article_number":"20170419","month":"10","title":"On the integrability of Birkhoff billiards","volume":376,"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","year":"2018","citation":{"ama":"Kaloshin V, Sorrentino A.

To preserve the switchability of these species under confinement, we work with a water-soluble coordination cage that is flexible enough to adapt its shape to the conformation of the encapsulated guest. We show that owing to its flexibility, the cage is not only capable of accommodating—and solubilizing in water—several light-responsive spiropyran-based molecular switches, but, more importantly, it also provides an environment suitable for the efficient, reversible photoisomerization of the bound guests.

The observation and quantification of chirality-sensitive signals, however, remains extremely challenging, especially on ultrafast timescales and in dilute media. Here, we describe the experimental realization of an all-optical and ultrafast scheme for detecting chiral dynamics in molecules. This technique is based on high-harmonic generation by a combination of two-color counterrotating femtosecond laser pulses with polarization states tunable from linear to circular. We demonstrate two different implementations of chiral-sensitive high-harmonic spectroscopy on an ensemble of randomly oriented methyloxirane molecules in the gas phase. Using two elliptically polarized fields, we observe that the ellipticities maximizing the harmonic signal reach up to \r\n4.4\r\n±\r\n0.2\r\n%\r\n (at 17.6 eV). Using two circularly polarized fields, we observe circular dichroisms ranging up to \r\n13\r\n±\r\n6\r\n%\r\n (28.3–33.1 eV). Our theoretical analysis confirms that the observed chiral response originates from subfemtosecond electron dynamics driven by the magnetic component of the driving laser field. This assignment is supported by the experimental observation of a strong intensity dependence of the chiral effects and its agreement with theory. We moreover report and explain a pronounced variation of the signal strength and dichroism with the driving-field ellipticities and harmonic orders. Finally, we demonstrate the sensitivity of the experimental observables to the shape of the electron hole. This technique for chiral discrimination will yield femtosecond temporal resolution when integrated in a pump-probe scheme and subfemtosecond resolution on chiral charge migration in a self-probing scheme.","lang":"eng"}],"year":"2018","citation":{"short":"D.R.

YaxB can subsequently be recruited to membrane-associated YaxA and induced to present its lytic transmembrane helices. Pore formation can progress by further oligomerization of YaxA–YaxB dimers.

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.","lang":"eng"}],"day":"21","arxiv":1,"doi":"10.1039/c8sm01760c","extern":"1","volume":14,"publication":"Soft Matter","month":"12","oa_version":"Preprint","keyword":["General Chemistry","Condensed Matter Physics"],"language":[{"iso":"eng"}],"type":"journal_article","date_published":"2018-12-21T00:00:00Z","oa":1,"publication_identifier":{"eissn":["1744-6848"],"issn":["1744-683X"]},"user_id":"D865714E-FA4E-11E9-B85B-F5C5E5697425","status":"public","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1909.11121"}]},{"abstract":[{"lang":"eng","text":"Biological membranes typically contain a large number of different components dispersed in small concentrations in the main membrane phase, including proteins, sugars, and lipids of varying geometrical properties. Most of these components do not bind the cargo. Here, we show that such “inert” components can be crucial for the precise control of cross-membrane trafficking. Using a statistical mechanics model and molecular dynamics simulations, we demonstrate that the presence of inert membrane components of small isotropic curvatures dramatically influences cargo endocytosis, even if the total spontaneous curvature of such a membrane remains unchanged. Curved lipids, such as cholesterol, as well as asymmetrically included proteins and tethered sugars can, therefore, actively participate in the control of the membrane trafficking of nanoscopic cargo. We find that even a low-level expression of curved inert membrane components can determine the membrane selectivity toward the cargo size and can be used to selectively target membranes of certain compositions. Our results suggest a robust and general method of controlling cargo trafficking by adjusting the membrane composition without needing to alter the concentration of receptors or the average membrane curvature. This study indicates that cells can prepare for any trafficking event by incorporating curved inert components in either of the membrane leaflets."}],"day":"18","doi":"10.1021/acs.nanolett.8b00786","external_id":{"pmid":["29667410"]},"year":"2018","citation":{"ieee":"T.
