--- _id: '10387' abstract: - lang: eng text: We report numerical simulations of membrane tubulation driven by large colloidal particles. Using Monte Carlo simulations we study how the process depends on particle size and binding strength, and present accurate free energy calculations to sort out how tube formation compares with the competing budding process. We find that tube formation is a result of the collective behavior of the particles adhering on the surface, and it occurs for binding strengths that are smaller than those required for budding. We also find that long linear aggregates of particles forming on the membrane surface act as nucleation seeds for tubulation by lowering the free energy barrier associated to the process. article_number: '188101' article_processing_charge: No article_type: original author: - first_name: Anđela full_name: Šarić, Anđela id: bf63d406-f056-11eb-b41d-f263a6566d8b last_name: Šarić orcid: 0000-0002-7854-2139 - first_name: Angelo full_name: Cacciuto, Angelo last_name: Cacciuto citation: ama: Šarić A, Cacciuto A.

This result is in net contrast with the isotropic aggregation of nanoparticles on fluid interfaces or the expected clustering of isotropic insertions in biological membranes. We present a phase diagram indicating where linear aggregation is expected and compute explicitly the free-energy barriers associated with linear and isotropic aggregation. Finally, we provide simple scaling arguments to explain this phenomenology. acknowledgement: "This work was supported by the National Science Foundation under Career Grant No. DMR-0846426.\r\n" article_number: '118101' article_processing_charge: No article_type: original author: - first_name: Anđela full_name: Šarić, Anđela id: bf63d406-f056-11eb-b41d-f263a6566d8b last_name: Šarić orcid: 0000-0002-7854-2139 - first_name: Angelo full_name: Cacciuto, Angelo last_name: Cacciuto citation: ama: Šarić A, Cacciuto A.

He had had upper back tension for 6 months. Medical history was unremarkable apart from moderate nicotine use (two pack-years). Echocardiography, electrocardiography, and laboratory tests were unremarkable, excluding a cardiac event. CT of the chest after chest radiography showed a large bulla of 16 cm diameter in the right hemithorax (figure A). We did not detect radiological evidence of underlying pulmonary disease. The bulla wall was unremarkable and no structures were seen within the bulla. acknowledgement: We thank the interdisciplinary team at the ELK Berlin Chest Hospital. article_processing_charge: No author: - first_name: Barbara full_name: Erne, Barbara last_name: Erne - first_name: Mareike full_name: Graff, Mareike last_name: Graff - first_name: Wolfram full_name: Klemm, Wolfram last_name: Klemm - first_name: Johann G full_name: Danzl, Johann G id: 42EFD3B6-F248-11E8-B48F-1D18A9856A87 last_name: Danzl orcid: 0000-0001-8559-3973 - first_name: Gunda full_name: Leschber, Gunda last_name: Leschber citation: ama: Erne B, Graff M, Klemm W, Danzl JG, Leschber G.

Starting from a Mott insulator with Cs atoms at weak repulsive interactions, we use a magnetic Feshbach resonance to tune the interactions to large attractive values and produce a metastable state pinned by attractive interactions with a lifetime on the order of 10 s. We probe the (de)excitation spectrum via lattice modulation spectroscopy, measuring the interaction dependence of two- and three-body bound-state energies. As a result of increased on-site three-body loss we observe resonance broadening and suppression of tunneling processes that produce three-body occupation. acknowledgement: We are indebted to R.

In this work we present cantilever torque magnetometry measurements of micron-size BSCCO flakes patterned with arrays of nanometer scale rings or holes. Using ultrasensitive dynamic torque magnetometry, oscillations in magnetization are observed near Tc as a function of the applied magnetic flux threading the array. Special effort was made to detect the oscillations in magnetization at temperatures above Tc, where the Nernst effect and magnetization measurements suggest the possibility of pairing. To constrain the magnitude of the coherence length in the fluctuation regime, we will present the dependence of the amplitude of the h/2e period oscillations as a function of temperature and hole size. acknowledgement: This work was supported by the Center for Emergent Superconductivity, an Energy Frontier Research Center funded by the U.S. DOE, Office of Science, under Award No. DE-AC0298CH1088. alternative_title: - Bulletin of the American Physical Society article_number: X21.00008 article_processing_charge: No author: - first_name: Hryhoriy full_name: Polshyn, Hryhoriy id: edfc7cb1-526e-11ec-b05a-e6ecc27e4e48 last_name: Polshyn orcid: 0000-0001-8223-8896 - first_name: Raffi full_name: Budakian, Raffi last_name: Budakian citation: ama: 'Polshyn H, Budakian R.
