Space asteroseismology is revolutionizing our knowledge of the internal structure and dynamics of stars. A breakthrough is ongoing with the recent discoveries of signatures of strong magnetic fields in the core of red giant stars. The key signature for such a detection is the asymmetry these fields induce in the frequency splittings of observed dipolar mixed gravito-acoustic modes.\r\nAims. We investigate the ability of the observed asymmetries of the frequency splittings of dipolar mixed modes to constrain the geometrical properties of deep magnetic fields.\r\nMethods. We used the powerful analytical Racah-Wigner algebra used in quantum mechanics to characterize the geometrical couplings of dipolar mixed oscillation modes with various realistically plausible topologies of fossil magnetic fields. We also computed the induced perturbation of their frequencies.\r\nResults. First, in the case of an oblique magnetic dipole, we provide the exact analytical expression of the asymmetry as a function of the angle between the rotation and magnetic axes. Its value provides a direct measure of this angle. Second, considering a combination of axisymmetric dipolar and quadrupolar fields, we show how the asymmetry is blind to the unraveling of the relative strength and sign of each component. Finally, in the case of a given multipole, we show that a negative asymmetry is a signature of non-axisymmetric topologies.\r\nConclusions. Asymmetries of dipolar mixed modes provide a key bit of information on the geometrical topology of deep fossil magnetic fields, but this is insufficient on its own. Asteroseismic constraints should therefore be combined with spectropolarimetric observations and numerical simulations, which aim to predict the more probable stable large-scale geometries.","lang":"eng"}]},{"publication_identifier":{"issn":["2663-337X"]},"alternative_title":["ISTA Thesis"],"month":"11","type":"dissertation","has_accepted_license":"1","doi":"10.15479/14547","citation":{"apa":"Phan, D.

research interest and they serve as the physical platform in many proposals towards topological quantum computation.\r\nDespite being under extensive investigations, historically using transport techniques, the basic properties of the interface between the superconductor and the semiconductor remain to be understood.\r\n\r\nIn this thesis, two separate studies on the Al-InAs heterostructures are reported with the first focusing on the physics of the material motivated by the emergence of a new phase, the Bogoliubov-Fermi surface. \r\nThe second focuses on a technological application, a gate-tunable Josephson parametric amplifier.\r\n\r\nIn the first study, we investigate the hypothesized unconventional nature of the induced superconductivity at the interface between the Al thin film and the InAs quantum well.\r\nWe embed a two-dimensional Al-InAs hybrid system in a resonant microwave circuit allowing measurements of change in inductance.\r\nThe behaviour of the resonance in a range of temperature and in-plane magnetic field has been studied and compared with the theory of conventional s-wave superconductor and a two-component theory that includes both contribution of the $s$-wave pairing in Al and the intraband $p \\pm ip$ pairing in InAs.\r\nMeasuring the temperature dependence of resonant frequency, no discrepancy is found between data and the conventional theory.\r\nWe observe the breakdown of superconductivity due to an applied magnetic field which contradicts the conventional theory.\r\nIn contrast, the data can be captured quantitatively by fitting to a two-component model.\r\nWe find the evidence of the intraband $p \\pm ip$ pairing in the InAs and the emergence of the Bogoliubov-Fermi surfaces due to magnetic field with the characteristic value $B^* = 0.33~\\mathrm{T}$.\r\nFrom the fits, the sheet resistance of Al, the carrier density and mobility in InAs are determined.\r\nBy systematically studying the anisotropy of the circuit response, we find weak anisotropy for $B < B^*$ and increasingly strong anisotropy for $B > B^*$ resulting in a pronounced two-lobe structure in polar plot of frequency versus field angle.\r\nStrong resemblance between the field dependence of dissipation and superfluid density hints at a hidden signature of the Bogoliubov-Fermi surface that is burried in the dissipation data.\r\n\r\nIn the second study, we realize a parametric amplifier with a Josephson field effect transistor as the active element.\r\nThe device's modest construction consists of a gated SNS weak link embedded at the center of a coplanar waveguide resonator.\r\nBy applying a gate voltage, the resonant frequency is field-effect tunable over a range of 2 GHz.\r\nModelling the JoFET minimally as a parallel RL circuit, the dissipation introduced by the JoFET can be quantitatively related to the gate voltage.\r\nWe observed gate-tunable Kerr nonlinearity qualitatively in line with expectation.\r\nThe JoFET amplifier has 20 dB of gain, 4 MHz of instantaneous bandwidth, and a 1dB compression point of -125.5 dBm when operated at a fixed resonant frequency.\r\nIn general, the signal-to-noise ratio is improved by 5-7 dB when the JoFET amplifier is activated compared.\r\nThe noise of the measurement chain and insertion loss of relevant circuit elements are calibrated to determine the expected and the real noise performance of the JoFET amplifier.\r\nAs a quantification of the noise performance, the measured total input-referred noise of the JoFET amplifier is in good agreement with the estimated expectation which takes device loss into account.\r\nWe found that the noise performance of the device reported in this document approaches one photon of total input-referred added noise which is the quantum limit imposed in nondegenerate parametric amplifier.","lang":"eng"}],"degree_awarded":"PhD","supervisor":[{"id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2607-2363","full_name":"Higginbotham, Andrew P","first_name":"Andrew

Such non-causal firing is contrary to the tenet of spikes as a means of communication, and its purpose remains unclear. We propose that self-initiated firing can serve as a release valve to protect neurons from the toxic conditions arising in mitochondria from lower-than-baseline energy consumption. To demonstrate the viability of our hypothesis, we built a set of models that incorporate recent experimental results indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP), adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing. We explore the relationship of metabolic cost of spiking with its effect on the temporal patterning of spikes and reproduce experimentally observed changes in intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with ROS-modulated potassium channels. We also show that metabolic spiking homeostasis can produce indefinitely sustained avalanche dynamics in cortical circuits. Our theory can account for key features of neuronal activity observed in many studies ranging from ion channel function all the way to resting state dynamics. We finish with a set of experimental predictions that would confirm an integrated, crucial role for metabolically regulated spiking and firmly link metabolic homeostasis and neuronal function.","lang":"eng"}],"status":"public","_id":"14666","title":"Metabolically regulated spiking could serve neuronal energy homeostasis and protect from reactive oxygen species","das_tickbox":"1","isi":1,"corr_author":"1","article_processing_charge":"Yes (in subscription journal)","day":"21","date_published":"2023-11-21T00:00:00Z","article_number":"e2306525120","file_date_updated":"2023-12-11T12:45:12Z","intvolume":" 120","issue":"48","citation":{"mla":"Chintaluri, Chaitanya, and Tim P.

The dependence of δ on ε in this result is notoriously difficult to determine: it is known that δ−1 must be at least super‐polynomial in ε−1, and that it is at most of tower type in εlog −1. We prove that if one imposes an appropriate minimum degree condition on G, then one can actually take δ to be a linear function of ε in the clique removal lemma. Moreover, we determine the threshold for such a minimum degree requirement, showing that above this threshold we have linear bounds, whereas below the threshold the bounds are once again super‐polynomial, as in the unrestricted removal lemma. We also investigate this question for other graphs besides cliques, and prove some general results about how minimum degree conditions affect the bounds in the graph removal lemma."}],"oa":1,"date_created":"2026-06-29T10:53:26Z","extern":"1","title":"Minimum degree and the graph removal lemma","status":"public","_id":"22164"},{"extern":"1","abstract":[{"text":"The book graph 𝐵(𝑘)\r\n𝑛 consists of 𝑛 copies of 𝐾𝑘+1 joined along a common 𝐾𝑘.

A connected graph H on n vertices is called p-good if r(Kp,H)=(p−1)(n−1)+1. Nikiforov and Rousseau proved that if n is sufficiently large in terms of p and k, then Bk,n is p-good. Their proof uses Szemerédi's regularity lemma and gives a tower-type bound on n. We give a short new proof that avoids using the regularity method and shows that every Bk,n with n≥2k10p is p-good.\r\nUsing Szemerédi's regularity lemma, Nikiforov and Rousseau also proved much more general goodness-type results, proving a tight bound on r(G,H) for several families of sparse graphs G and H as long as |V(G)|<δ|V(H)| for a small constant δ>0. Using our techniques, we prove a new result of this type, showing that r(G,H)=(p−1)(n−1)+1 when H=Bk,n and G is a complete p-partite graph whose first p−1 parts have constant size and whose last part has size δn, for some small constant δ>0.

Inherently invisible to crystallography, aromatic motions have been primarily studied by solution NMR. The question how packing of proteins in crystals affects ring flips has, thus, remained largely unexplored. Here we apply magic-angle spinning NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a protein in three different crystal packing environments to shed light onto possible impact of packing on ring flips. The flips of the two Phe residues in ubiquitin, both surface exposed, appear remarkably conserved in the different crystal forms, even though the intermolecular packing is quite different: Phe4 flips on a ca. 10–20 ns time scale, and Phe45 are broadened in all crystals, presumably due to µs motion. Our findings suggest that intramolecular influences are more important for ring flips than intermolecular (packing) effects."}],"date_created":"2023-01-12T11:55:38Z","oa":1,"status":"public","_id":"12114","title":"Aromatic ring flips in differently packed ubiquitin protein crystals from MAS NMR and MD"},{"intvolume":" 11","publisher":"Frontiers","file":[{"date_created":"2023-08-07T07:48:11Z","creator":"dernst","file_name":"2023_FrontiersPhysics_Hasler.pdf","file_id":"13978","file_size":2421758,"access_level":"open_access","date_updated":"2023-08-07T07:48:11Z","content_type":"application/pdf","success":1,"relation":"main_file","checksum":"fb36dda665e57bab006a000bf0faacd5"}],"citation":{"short":"R.

To this end, the combination of an electrolyte-gated field-effect transistor (EG-FET) with a fiber optic-coupled surface plasmon resonance (FO-SPR) probe serving as gate electrode has been investigated to deconvolute surface mass and charge density variations associated to surface reactions. However, applying an electrochemical potential on such gold-coated FO-SPR gate electrodes can induce gradual morphological changes of the thin gold film, leading to an irreversible blue-shift of the SPR wavelength and a substantial signal drift. We show that mild annealing leads to optical and electronic signal stabilization (20-fold lower signal drift than as-sputtered fiber optic gates) and improved overall analytical performance characteristics. The thermal treatment prevents morphological changes of the thin gold-film occurring during operation, hence providing reliable and stable data immediately upon gate voltage application. Thus, the readout output of both transducing principles, the optical FO-SPR and electronic EG-FET, stays constant throughout the whole sensing time-window and the long-term effect of thermal treatment is also improved, providing stable signals even after 1 year of storage. Annealing should therefore be considered a necessary modification for applying fiber optic gate electrodes in real-time multimodal investigations of surface reactions at the solid-liquid interface.","lang":"eng"}],"date_created":"2023-08-06T22:01:11Z","oa":1,"isi":1},{"type":"research_data_reference","has_accepted_license":"1","doi":"10.5281/ZENODO.7716920","title":"Optical and electronic signal stabilization of plasmonic fiber optic gate electrodes: Towards improved real-time dual-mode biosensing","_id":"19308","status":"public","month":"07","date_created":"2025-03-07T08:40:58Z","oa":1,"abstract":[{"lang":"eng","text":"This Dataset contains the raw data from the following publication: \"Optical and electronic signal stabilization of plasmonic fiber optic gate electrodes: towards improved real-time dual-mode biosensing\" (DOI 10.3389/fphy.2023.1202132)"}],"OA_place":"repository","oa_version":"Published Version","author":[{"last_name":"Hasler","first_name":"Roger","full_name":"Hasler, Roger"},{"last_name":"Polt","first_name":"Marie-Helene","full_name":"Polt, Marie-Helene"},{"first_name":"Ciril","last_name":"Reiner-Rozman","full_name":"Reiner-Rozman, Ciril"},{"last_name":"Fossati","first_name":"Stefan","full_name":"Fossati, Stefan"},{"first_name":"Seungho","last_name":"Lee","full_name":"Lee, Seungho"},{"full_name":"Aspermair, Patrik","first_name":"Patrik","last_name":"Aspermair"},{"last_name":"Kleber","first_name":"Christoph","full_name":"Kleber, Christoph"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","first_name":"Maria","last_name":"Ibáñez"},{"full_name":"Dostalek, Jakub","last_name":"Dostalek","first_name":"Jakub"},{"full_name":"Knoll, Wolfgang","last_name":"Knoll","first_name":"Wolfgang"}],"department":[{"_id":"MaIb"}],"related_material":{"record":[{"id":"13968","relation":"used_in_publication","status":"public"}]},"date_updated":"2026-07-22T06:16:48Z","ddc":["540"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"citation":{"mla":"Hasler, Roger, et al.

This paper studies broadcast problems in various innovative models where the communication network connecting n processes is dynamic (e.g., due to mobility or failures) and controlled by an adversary. \r\nIn the first model, the processes transitively communicate their ids in synchronous rounds along a rooted tree given in each round by the adversary whose goal is to maximize the number of rounds until at least one id is known by all processes. Previous research has shown a ⌈(3n-1)/2⌉-2 lower bound and an O(nlog log n) upper bound. We show the first linear upper bound for this problem, namely ⌈(1+√2) n-1⌉ ≈ 2.4n.\r\nWe extend these results to the setting where the adversary gives in each round k-disjoint forests and their goal is to maximize the number of rounds until there is a set of k ids such that each process knows of at least one of them. We give a ⌈3(n-k)/2⌉-1 lower bound and a (π²+6)/6 n+1 ≈ 2.6n upper bound for this problem.\r\nFinally, we study the setting where the adversary gives in each round a directed graph with k roots and their goal is to maximize the number of rounds until there exist k ids that are known by all processes. We give a ⌈3(n-3k)/2⌉+2 lower bound and a ⌈(1+√2)n⌉+k-1 ≈ 2.4n+k upper bound for this problem.\r\nFor the two latter problems no upper or lower bounds were previously known.","lang":"eng"}],"extern":"1","citation":{"ama":"El-Hayek A, Henzinger M, Schmid S.
