Full 3D motion control for programmable bevel-tip steerable needles
Creators: name: Donder, Abdulhamit
Publisher: name: Imperial College London
Year: 2021

description: Minimally invasive surgery has been in the focus of many researchers due to its reduced intra- and post-operative risks when compared to an equivalent open surgery approach. In the context of minimally invasive surgery, percutaneous intervention, and particularly, needle insertions, are of great importance in tumour-related therapy and diagnosis. However, needle and tissue deformation occurring during needle insertion often results in misplacement of the needles, which leads to complications, such as unsuccessful treatment and misdiagnosis. To this end, steerable needles have been proposed to compensate for placement errors by allowing curvilinear navigation. A particular type of steerable needle is the programmable bevel-tip steerable needle (PBN), which is a bio-inspired needle that consists of relatively soft and slender segments. Due to its flexibility and bevel-tip segments, it can navigate through 3D curvilinear paths. In PBNs, steering in a desired direction is performed by actuating particular PBN segments. Therefore, the pose of each segment is needed to ensure that the correct segment is actuated. To this end, in this thesis, proprioceptive sensing methods for PBNs were investigated. Two novel methods, an electromagnetic (EM)-based tip pose estimation method and a fibre Bragg grating (FBG)-based full shape sensing method, were presented and evaluated. The error in position was observed to be less than 1.08 mm and 5.76 mm, with the proposed EM-based tip tracking and FBG-based shape reconstruction methods, respectively. Moreover, autonomous path-following controllers for PBNs were also investigated. A closed-loop, 3D path-following controller, which was closed via feedback from FBG-inscribed multi-core fibres embedded within the needle, was presented. The nonlinear guidance law, which is a well-known approach for path-following control of aerial vehicles, and active disturbance rejection control (ADRC), which is known for its robustness within hard-to-model environments, were chosen as the control methods. Both linear and nonlinear ADRC were investigated, and the approaches were validated in both ex vivo brain and phantom tissue, with some of the experiments involving moving targets. The tracking error in position was observed to be less than 6.56 mm.

title: Outcomes and long-term follow-up of 106 cats treated with subcutaneous ureteral bypass for ureteral obstruction

description: Subcutaneous ureteral bypass (SUB) is the main therapy for cats with benign
ureteral obstructions (UO). However, variables associated with outcome and disease
progression remain to be characterized. In this retrospective study, medical records
of all cats treated with SUB (Vetsuisse Faculty of Bern, 2014-2020) were reviewed
(n=106 cats). Short-term outcome was defined as hospital discharge; long-term
outcome as the rate of progression of serum creatinine >120 days after surgery.
Hospital discharge rate was 86%. During follow-up, 22% of the cats required revision
surgeries and 27% had ≥1 positive urine culture. Median survival time was 1.9 years
(95% confidence interval, 1.4-3.2), with 50% urinary-related causes of death. Of the
clinical variables available at presentation, only younger age was associated with
better short-term outcome (P=.008). A lower creatinine at discharge was associated
with favorable long-term outcome (P=.02). The median increase in serum creatinine
during follow-up was 0.14 mg/dL/year (interquartile range, -0.05 to 0.83); 75% of the
cats were classified as stable. Positive urine cultures at the time of diagnosis or
treatment with hemodialysis before surgery for severe azotemia were not associated
with outcome. In conclusion, SUB devices are a feasible option to treat cats with UO,
associated with slow progression of chronic kidney disease and long survival time.
Positive urine culture or severe azotemia at presentation do not predict a worse
outcome.
Reflection and time reversal symmetry enriched topological phases of matter: path integrals, non-orientable manifolds, and anomalies

description: We study symmetry-enriched topological (SET) phases in 2+1 space-time dimensions with spatial reflection and/or time-reversal symmetries. We provide a systematic construction of a wide class of reflection and time-reversal SET phases in terms of a topological path integral defined on general space-time manifolds. An important distinguishing feature of different topological phases with reflection and/or time-reversal symmetry is the value of the path integral on non-orientable space-time manifolds. We derive a simple general formula for the path integral on the manifold $Σ^2 \times S^1$, where $Σ^2$ is a two-dimensional non-orientable surface and $S^1$ is a circle. This also gives an expression for the ground state degeneracy of the SET on the surface $Σ^2$ that depends on the reflection symmetry fractionalization class, generalizing the Verlinde formula for ground state degeneracy on orientable surfaces. Consistency of the action of the mapping class group on non-orientable manifolds leads us to a constraint that can detect when a time-reversal or reflection SET phase is anomalous in (2+1)D and, thus, can only exist at the surface of a (3+1)D symmetry protected topological (SPT) state. Given a (2+1)D reflection and/or time-reversal SET phase, we further derive a general formula that determines which (3+1)D reflection and/or time-reversal SPT phase hosts the (2+1)D SET phase as its surface termination. A number of explicit examples are studied in detail.

Auch in anderen Ländern werden mangelnde Mathematikkenntnisse und das Fehlen von grundlegenden Fertigkeiten beklagt: „A widespread decrease in levels of mathematical competence, including a lack of essential technical facility, a marked decline in analytical powers, and changed perceptions of what mathematics is, especially with regard to the place of precision and proof, have been noted in reports (…), with these difficulties even extend to ‚high-attaining‘ students.“ (Hong et al., 2009, S. 250).

description: We construct inflationary models in the context of supergravity with orthogonal nilpotent superfields [1]. When local supersymmetry is gauge-fixed in the unitary gauge, these models describe theories with only a single real scalar (the inflaton), a graviton and a gravitino. Critically, there is no inflatino, no sgoldstino, and no sinflaton in these models. This dramatically simplifies cosmological models which can simultaneously describe inflation, dark energy and SUSY breaking.

description: Nitrous oxide is a gas often used in dental, surgical and veterinary operations as an anesthetic agent. Employees stationed in proximity of fugitive gas emissions may potentially suffer adverse health effects from chronic exposure to this agent. Passive dosimeters can be worn in the breathing zone of potentially affected personnel during exposure periods, then later analyzed to quantify nitrous oxide exposure. This study sought to establish the accuracy of several commercially available passive monitoring devices for nitrous oxide by comparison against an infra-red spectrophotometric reference method.

title: Efficient Gaussian process updating under linear operator data for uncertainty reduction on implicit sets in Bayesian inverse problems
Creators: name: Travelletti, Cédric
Publisher: name: Universität Bern
Year: 2023
Subjects: subject: 510 Mathematics
subject: 550 Earth sciences & geology

description: This thesis aims at developing sequential uncertainty reduction techniques for set
estimation in Bayesian inverse problems. Sequential uncertainty reduction (SUR)
strategies provide a statistically principled way of designing data collection plans
that optimally reduce the uncertainty on a given quantity of interest. This thesis
focusses on settings where the quantity of interest is a set that is implicitly defined
by conditions on some unknown function and one is only able to observe the values
of linear operators applied to the function. This setting corresponds to the one encoutered
in linear inverse problems and proves to be challenging for SUR techniques.
Indeed, SUR relies on having a probabilistic model for the unknown function under
consideration, and these models become untractable for moderately sized problem.
We start by introducing an implicit representation for covariance matrices of Gaussian
processes (GP) to overcome this limitation, and demonstrate how it allows one
to perform SUR for excursion set estimation in a real-world 3D gravimetric inversion
problem on the Stromboli volcano. In a second time, we focus on extending vanilly
SUR to multivariate problems. To that end, we introduce the concept of 'generalized
locations', which allows us to rewrite the co-kriging equations in a form-invariant
way and to derive semi-analytical formulae for multivariate SUR criteria. Those
approaches are demonstrated on a river plume estimation problem. After having
extended SUR for inverse problems to large-scale and multivariate settings, we devote
our attention to improving the realism of the models by including user-defined
trends. We show how this can be done by extending universal kriging to inverse
problems and also provide fast k-fold cross-validation formulae. Finally, in order to
provide theoretical footing for the developed approaches, show how the conditional
law of a GP can be seen as a disintegration of a corresponding Gaussian measure
under some suitable condition.

description: We develop a computational method for extremal Steklov eigenvalue problems and apply it to study the problem of maximizing the $p$-th Steklov eigenvalue as a function of the domain with a volume constraint. In contrast to the optimal domains for several other extremal Dirichlet- and Neumann-Laplacian eigenvalue problems, computational results suggest that the optimal domains for this problem are very structured. We reach the conjecture that the domain maximizing the $p$-th Steklov eigenvalue is unique (up to dilations and rigid transformations), has p-fold symmetry, and an axis of symmetry. The $p$-th Steklov eigenvalue has multiplicity 2 if $p$ is even and multiplicity 3 if $p\geq3$ is odd.

description: A parallel fast direct solver for rank-compressible block tridiagonal linear systems is presented. Algorithmic synergies between Cyclic Reduction and Hierarchical matrix arithmetic operations result in a solver with $O(N \log^2 N)$ arithmetic complexity and $O(N \log N)$ memory footprint. We provide a baseline for performance and applicability by comparing with well known implementations of the $\mathcal{H}$-LU factorization and algebraic multigrid with a parallel implementation that leverages the concurrency features of the method. Numerical experiments reveal that this method is comparable with other fast direct solvers based on Hierarchical Matrices such as $\mathcal{H}$-LU and that it can tackle problems where algebraic multigrid fails to converge.

description: The boolean Pythagorean Triples problem has been a longstanding open problem in Ramsey Theory: Can the set N = $\{1, 2, ...\}$ of natural numbers be divided into two parts, such that no part contains a triple $(a,b,c)$ with $a^2 + b^2 = c^2$ ? A prize for the solution was offered by Ronald Graham over two decades ago. We solve this problem, proving in fact the impossibility, by using the Cube-and-Conquer paradigm, a hybrid SAT method for hard problems, employing both look-ahead and CDCL solvers. An important role is played by dedicated look-ahead heuristics, which indeed allowed to solve the problem on a cluster with 800 cores in about 2 days. Due to the general interest in this mathematical problem, our result requires a formal proof. Exploiting recent progress in unsatisfiability proofs of SAT solvers, we produced and verified a proof in the DRAT format, which is almost 200 terabytes in size. From this we extracted and made available a compressed certificate of 68 gigabytes, that allows anyone to reconstruct the DRAT proof for checking.

description: Activation barriers associated with ion diffusion and chemical reactions are vital to understand and predict a wide range of phenomena, such as material growth, ion transport, and catalysis. In the calculation of activation barriers for non-redox processes in semiconductors and insulators, it has been widely assumed that the charge state remains fixed to that of the initial electronic ground state throughout a dynamical process. In this work, we demonstrate that this assumption is generally inaccurate and that a rate-limiting transition state can have a different charge state from the initial ground state. This phenomenon can significantly lower the activation barrier of dynamical process that depends strongly on charge state, such as carbon vacancy diffusion in 4H-SiC. With inclusion of such transition state redox, the activation barrier varies continuously with Fermi level, in contrast to the step-line feature predicted by the traditional fixed-charge assumption. In this study, a straightforward approach to include the transition state redox effect is provided, the typical situations where the effect plays a significant role are identified, and the relevant electron dynamics are discussed.

description: Asymmetry measurements are common in collider experiments and can sensitively probe particle properties. Typically, data can only be measured in a finite region covered by the detector, so an extrapolation from the visible asymmetry to the inclusive asymmetry is necessary. Often a constant multiplicative factor is more than adequate for the extrapolation and this factor can be readily determined using simulation methods. However, there is a potential, avoidable pitfall involved in the determination of this factor when the asymmetry in the simulated data sample is small. We find that to obtain a reliable estimate of the extrapolation factor, the number of simulated events required rises as the inverse square of the simulated asymmetry; this can mean that an unexpectedly large sample size is required when determining its value.

For $H=1/2$, Brownian motion is recovered. We develop a perturbative approach to treat the non-locality in time in an expansion in $\varepsilon = H-1/2$. This allows us to derive analytic results beyond scaling exponents for various observables related to extreme value statistics: The maximum $m$ of the process and the time $t_{\text{max}}$ at which this maximum is reached, as well as their joint distribution. We test our analytical predictions with extensive numerical simulations for different values of $H$. They show excellent agreement, even for $H$ far from $1/2$.

description: Randomly coupled neural fields demonstrate chaotic variation of firing rates, if the coupling is strong enough, as has been shown by Sompolinsky et. al [Phys. Rev. Lett., v. 61, 259 (1988)]. We present a method for reconstruction of the coupling matrix from the observations of the chaotic firing rates. The approach is based on the particular property of the nonlinearity in the coupling, as the latter is determined by a sigmoidal gain function. We demonstrate that for a large enough data set, the method gives an accurate estimation of the coupling matrix and of other parameters of the system, including the gain function.

description: Identifying the functional networks underpinning indirectly observed processes poses an inverse problem for neurosciences or other fields. A solution of such inverse problems estimates as a first step the activity emerging within functional networks from EEG or MEG data. These EEG or MEG estimates are a direct reflect functional brain network activity with a temporal resolution that no other in vivo neuroimage may provide. A second step estimating functional connectivity from such activity pseudodata unveil the oscillatory brain networks that strongly correlate with all cognition and behavior. Simulations of such MEG or EEG inverse problem also reveal estimation errors of the functional connectivity determined by any of the state-of-the-art inverse solutions. We disclose a significant cause of estimation errors originating from misspecification of the functional network model incorporated into either inverse solution steps. We introduce the Bayesian identification of a Hidden Gaussian Graphical Spectral (HIGGS) model specifying such oscillatory brain networks model. In human EEG alpha rhythm simulations estimation errors measured as ROC performance do not surpass 2% in our HIGGS inverse solution and reach 20% in state-of-the-art methods. Macaque simultaneous EEG/ECoG recordings provide experimental confirmation for our inverse-solution with 1/3 more congruence according to Riemannian distances than state-of-the-art methods.

Ultraviolet Complete Quantum Field Theory and Particle Model

description: An ultraviolet complete particle model is constructed for the observed particles of the standard model. The quantum field theory associates infinite derivative entire functions with propagators and vertices, which make quantum loops finite and maintain Poincaré invariance and unitarity of the model. The electroweak model $SU(2)\times U(1)$ group is treated as a broken symmetry group with non-vanishing experimentally determined boson and fermion masses. A spontaneous symmetry breaking of the vacuum by a scalar Higgs field is not invoked to restore boson and fermion masses to the initially massless $SU(2)\times U(1)$ Lagrangian of the standard model. The hierarchy naturalness problem of the Higgs boson mass is resolved and the model contains only experimentally observed masses and coupling constants. The model can predict a stable vacuum evolution. Experimental tests to distinguish the standard model from the alternative model are proposed. The finite quantum field theory can be extended to quantum gravity.

A spectral projection method for transmission eigenvalues

description: In this paper, we consider a nonlinear integral eigenvalue problem, which is a reformulation of the transmission eigenvalue problem arising in the inverse scattering theory. The boundary element method is employed for discretization, which leads to a generalized matrix eigenvalue problem. We propose a novel method based on the spectral projection. The method probes a given region on the complex plane using contour integrals and decides if the region contains eigenvalue(s) or not. It is particularly suitable to test if zero is an eigenvalue of the generalized eigenvalue problem, which in turn implies that the associated wavenumber is a transmission eigenvalue. Effectiveness and efficiency of the new method are demonstrated by numerical examples.

Police Broadcast Communication: Analyzing how speech-emotion affects police communication

Subjects: subject: Police+ Broadcast Communication+ Sound+ Dominance+ Power asymmetry+ Dispatcher

description: Broadcast Police Communication (BPC) is sociologically significant because it provides a framework wherein power, social relationships, effective communication, cooperation, and interdependence can all be investigated simultaneously and in real time. The most prevalent type of BPC is one that involves a patrol unit and/or a police dispatcher making contact with a law enforcement officer (LEO). The average length of these dialogues is less than 2 seconds, yet they provide background for analyzing the interplay of power and dominance amongst the participants at the micro-, meso-, and macro-scales. The idea of dominance differs across the social and computational sciences. Dominance in the social sciences is centered on interpersonal behaviors that are indicators of micro aggressions. They are typical of social hierarchies, and the attitudes/behaviors contribute to the stabilization and perpetuation of social hierarchies. On the other hand, dominance in Speech Emotion Recognition (SER) is defined as the nonverbal vocal characteristics that indicate one's sense of power or submission in conversations. Acoustic characteristics such as fundamental frequency (voice pitch), formant frequency (frequency peak in voice that results from an acoustic resonance of the human vocal tract), loudness, breeziness in voice, speech rate, vocal variability etc. play key roles in the perception and assessment of dominance in human conversations. The evaluation of dominance characteristics can explain how aspects of control/submission might direct the conversation and, as a result, guides the outcome of the dialogue. The study revealed that context and structure of the BPC affects how participants listen to and interpret BPC messages. The low overall reliability of the labels for dominance between the annotators highlighted the importance of familiarity with the radio codes in individual’s response to radio communication.

description: Several transiting hot Jupiters orbit relatively inactive main-sequence stars. For some of those, the logR'HK activity parameter lies below the basal level (-5.1). Two explanations have been proposed so far: (i) the planet affects the stellar dynamo, (ii) the logR'HK measurements are biased by extrinsic absorption, either by the interstellar medium (ISM) or by material local to the system. We present here Hubble Space Telescope/COS far-UV spectra of WASP-13, which hosts an inflated hot Jupiter and has a measured logR'HK value (-5.26), well below the basal level. From the star's spectral energy distribution we obtain an extinction E(B-V) = 0.045+/-0.025 mag and a distance d = 232+/-8 pc. We detect at >4 sigma lines belonging to three different ionization states of carbon (C1, C2, and C4) and the Si4 doublet at ~3 sigma. Using far-UV spectra of nearby early G-type stars of known age, we derive a C4/C1 flux ratio-age relation, from which we estimate WASP-13's age to be 5.1+/-2.0 Gyr. We rescale the solar irradiance reference spectrum to match the flux of the C4 1548 doublet. By integrating the rescaled solar spectrum, we obtain an XUV flux at 1 AU of 5.4 erg s^-1 cm^-2. We use a detailed model of the planet's upper atmosphere, deriving a mass-loss rate of 1.5x10^11 g s^-1. Despite the low logR'HK value, the star shows a far-UV spectrum typical of middle-aged solar-type stars, pointing toward the presence of significant extrinsic absorption. The analysis of a high-resolution spectrum of the Ca2H&K lines indicates that the ISM absorption could be the origin of the low logR'HK value. Nevertheless, the large uncertainty in the Ca2 ISM abundance does not allow us to firmly exclude the presence of circumstellar gas.

description: The disciplinary fields of Arts (photography, visual and performing arts, such as dance, theatre and cinema), Design (including sub-disciplines such as visual communication, industrial design, fashion design and interaction design) and Music (including sound and aural arts) present a series of complex issues related to the reuse and distribution of artwork and of third parties content under copyright, not accessible in public domain and subject to a series of restrictions. These disciplinary fields produce a wide range of multimedia outputs, they imply action-research and practice-based research, and they collaborate with specialized national Swiss publishing houses. This situation makes the implementation of Open Access in the disciplinary fields of ADM (Arts, Design and Music) particularly complex. At the same time, practices developed within these fields address issues which are relevant in other disciplines. The present project proposal aims at supporting the Swiss disciplinary field of ADM in implementing the swissuniversities Open Access action plan 2021-2024 in collaboration with key stakeholders. More specifically the project involves a network of Swiss schools of ADM and it develops centralised and local services. The centralised service produces guidelines and solutions for a selection of case studies with the support of a legal team, it produces webinars and training for the local staff, it involves Swiss institutions in international networks and it triggers Green and Gold Open Access among the publications in the field of ADM. At a local level, the different schools involved notify case studies, receive training and coaching to support their researchers, teachers and collaborators, to include Open Access and Open Data (i.e. copyright management, open licenses, multimedia formats, reviewing processes) within students’ curricula and to negotiate with national publishers specialised in ADM. The project contributes to alternative forms of publications and it participates to international initiatives: it implements in 2022 the guidelines, in 2023 training and coaching, and in 2024 the negotiations with institutional, national and international publishers.
