description: In this study, we present results from experiments on the retention of single oil droplets rising through a two-layer density stratification. These experiments confirm the significant slowdown observed in past literature of settling and rising particles and droplets in stratification, and are the first experiments to study single liquid droplets as opposed to solid particles. By tracking the motion of the droplets as they rise through a stratified fluid, we identify two timescales which quantitatively describe this slowdown: an entrainment timescale, and a retention timescale. The entrainment timescale is a measure of the time that a droplet spends below its upper-layer terminal velocity and relates to the length of time over which the droplet's rise is affected by entrained dense fluid. The retention time is a measure of the time that the droplet is delayed from reaching an upper threshold far from the density transition. Both timescales are found to depend on the Froude and Reynolds numbers of the system, Fr $=U_u/(Nd)$ and Re $=ρ_u U_u d/ν$. We find that both timescales are only significantly large for Fr $\lesssim1$, indicating that trapping dynamics in a relatively sharp stratification arise from a balance between drop inertia and buoyancy. Finally, we present a theoretical formulation for the drag enhancement $Γ$, the ratio between the maximum stratification force and the corresponding drag force on the droplet, based on a simple force balance at the point of the velocity minimum. Using our experimental data, we find that our formulation compares well with recent theoretical and computational work by Zhang et al. [J. Fluid Mech. 875, 622-656 (2019)] on the drag enhancement on a solid sphere settling in a stratified fluid, and provides the first experimental data supporting their approach.

description: Let G be a finite group acting on a symplectic complex vector space V. Assume that the quotient V/G has a holomorphic symplectic resolution. We prove that G is generated by "symplectic reflectionsd"', i.e. symplectomorphisms with fixed space of codimension 2 in V. Symplectic resolutions are always semismall. A crepant resolution of V/G is always symplectic. We give a symplectic version of Nakamura conjectures.

description: An outbreak of tsetse-transmitted trypanosomiasis resulted in more than 50% losses of domestic pigs in the Eastern Region of Ghana (source: Veterinary Services, Accra; April 2007). In a control trial from May 4th–October 10th 2007, the efficacy of insecticide-treated mosquito fences to control tsetse was assessed. Two villages were selected – one serving as control with 14 pigsties and one experimental village where 24 pigsties were protected with insecticide treated mosquito fences. The 100 cm high, 150denier polyester fences with 100 mg/m2 deltamethrin and a UV protector were attached to surrounding timber poles and planks. Bi-monthly monitoring of tsetse densities with 10 geo-referenced bi-conical traps per village showed a reduction of more than 90% in the protected village within two months. Further reductions exceeding 95% were recorded during subsequent months. The tsetse population in the control village was not affected, only displaying seasonal variations. Fifty pigs from each village were ear-tagged and given a single curative treatment with diminazene aceturate (3.5 mg/kg bw) after their blood samples had been taken. The initial trypanosome prevalence amounted to 76% and 72% of protected and control animals, respectively, and decreased to 16% in protected as opposed to 84% in control pigs three months after intervention. After six months 8% of the protected pigs were infected contrasting with 60% in the control group.

description: Auf Grundlage eines Mikrocontrollers wurde ein USB-Datenlogger entwickelt, der es auf ein-fachste Weise ermöglicht, Messdaten aus Praktikumsversuchen auf einem USB-Stick mit in die Nachbereitung zu nehmen. Dafür sind weder Rechner im Praktikum noch teure Interface-Systeme und die zugehörige Software nötig. Praktikumsversuche sind in er Regel ‚Interventionen’, bei denen das Experiment im Fokus steht. Um eine Langzeitwirkung zu erzielen, werden Praktika sowohl ausführlich vor- als auch nachbereitet. Als Erweiterung bisher bekannter Interaktiver Bild-schirmexperimente (IBE) wurde nun eine Möglichkeit geschaffen, die im Praktikum aufgenom-menen Messdaten mitzunehmen und in entsprechende IBE einzubinden. So kann das Experiment – genau wie es im Praktikum abgelaufen ist – auf dem Bildschirm wiederholt bzw. nachvollzogen werden. Außerdem können die Messdaten zur Auswertung in Heimarbeit mit entsprechenden Programmen genutzt werden. Im Rahmen dieses Beitrags soll der entwickelte USB-Datenlogger vorgestellt und an einem Beispielexperiment die Einbindung der Messdaten in ein IBE illustriert werden.
Strong conciseness in profinite groups

description: A group word $w$ is said to be strongly concise in a class $\mathcal{C}$ of profinite groups if, for every group $G$ in $\mathcal{C}$ such that $w$ takes less than $2^{\aleph_0}$ values in $G$, the verbal subgroup $w(G)$ is finite. Detomi, Morigi and Shumyatsky established that multilinear commutator words -- and the particular words $x^2$ and $[x^2,y]$ -- have the property that the corresponding verbal subgroup is finite in a profinite group $G$ whenever the word takes at most countably many values in $G$. They conjectured that, in fact, this should be true for every word. In particular, their conjecture included as open cases power words and Engel words. In the present paper, we take a new approach via parametrised words that leads to stronger results. First we prove that multilinear commutator words are strongly concise in the class of all profinite groups. Then we establish that every group word is strongly concise in the class of nilpotent profinite groups. From this we deduce, for instance, that, if $w$ is one of the group words $x^2$, $x^3$, $x^6$, $[x^3,y]$ or $[x,y,y]$, then $w$ is strongly concise in the class of all profinite groups. Indeed, the same conclusion can be reached for all words of the infinite families $[x^m,z_1,\ldots,z_r]$ and $[x,y,y,z_1,\ldots,z_r]$, where $m \in \{2,3\}$ and $r \ge 1$.

Subjects: subject: 500 Naturwissenschaften und Mathematik::510 Mathematik

description: Biological function relies on the fact that biomolecules can switch between different conformations and aggregation states. Such transitions involve a rearrangement of parts of the biomolecules involved that act as dynamic domains. The reliable identification of such domains is thus a key problem in biophysics. In this work we present a method to identify semi-rigid domains based on dynamical data that can be obtained from molecular dynamics simulations or experiments. To this end the average inter-atomic distance- deviations are computed. The resulting matrix is then clustered by a constrained quadratic optimization problem. The reliability and performance of the method are demonstrated for two artificial peptides. Furthermore we correlate the mechanical properties with biological malfunction in three variants of amyloidogenic transthyretin protein, where the method reveals that a pathological mutation destabilizes the natural dimer structure of the protein. Finally the method is used to identify functional domains of the GroEL-GroES chaperone, thus illustrating the efficiency of the method for large biomolecular machines.

description: Gravimetric sensing with microresonators is the most accurate means for molecular recognition applications, i.e. specific molecule sensing. The molecular recognition sensitivity is determined by frequencyquality factor (fQ) figure of merit, which is influenced by resonator’s type, geometry, material, and damping parameters. Cubic silicon carbide has outstanding mechanical and chemical properties, which make it excellent for resonant sensing applications. We have fabricated epitaxial silicon carbide on silicon resonators using silicon surface micromachining. We demonstrate that outstanding fxQ products could be achieved on string resonators: by increasing the length and the tensile stress, by high vacuum operation, and by improvement of crystal quality and clamping condition. We have achieved fxQ products in the order of ~1012 Hz, which are better than the state-of-the-art silicon nitride strings. We also show the reduction of metal damping by growing graphene overlayer on epitaxial silicon carbide membranes, through a novel transfer-free alloy-mediated approach, for electrical transduction purposes. We report that graphene results in much smaller quality factor reduction (factor of 2) as compared to conventional metals overlayer (an order of magnitude). This is the highest transfer-free quality graphene reported so far on large silicon substrates; based on solid source growth from epitaxial silicon carbide.

description: We examine, from a geometrical point of view, the dynamics of a relativistic extended object with loaded edges. In the case of a Dirac-Nambu-Goto [DNG] object with DNG edges, the worldsheet $m$ generated by the parent object is, as in the case without boundary, an extremal timelike surface in spacetime. Using simple variational arguments, we demonstrate that the worldsheet of each edge is a constant mean curvature embedded timelike hypersurface on $m$, which coincides with its boundary, $\partial m$. The constant is equal in magnitude to the ratio of the bulk to the edge tension. The edge, in turn, exerts a dynamical influence on the motion of the parent through the boundary conditions induced on $m$, specifically that the traces of the projections of the extrinsic curvatures of $m$ onto $\partial m$ vanish.

description: Colloidal robots refer to the colloid scale (from nm to μm) machines capable of carrying out programmed actions for complex tasks automatically. Because of its promising application in engineering and medical service, colloidal robotics have been of much recent research interest in both theoretical and technological relevance. However, there remain many open challenges on increasing actuation efficiency, achieving high level tasks (e.g., autonomous navigation), etc. This dissertation, in general, focuses on developing new actuation mechanisms and designing autonomous navigation strategies for colloidal robots with both experimental and computational efforts. Firstly, the motivation, background and recent research advances on colloidal robots are reviewed. In Chapter 2, a high-efficiency actuation method called contact charge electrophoresis(CCEP) is introduced to propel the dielectric metallic Janus colloid particles. The autonomous propulsion of Janus particles shows colloidal particle asymmetries can be used to direct the motions of colloidal robots. Beyond single colloidal particle's propulsion, Chapter 3 shows multi-colloidal particles' motions can be coupled and synchronized to generate traveling waves via electrostatic interactions. Our results in Chapter 3 suggest that simple energy inputs can coordinate complex motions for colloidal robots. Then inspired by active particles motions' guided by their symmetry in Chapter 2, we show in Chapter 4 how multiple autonomous navigation can be achieved by designing the active particle's geometry and its stimulus response. Chapter 4 describes a strategy that colloid particles can sense the stimulus in environment via shape-shifting. The feedback loop of sensing and motion enables colloid particles to achieve positive or negative chemotaxis-like navigation. To experimentally realize similar navigation behaviors introduced in Chapter 4, we described a magnetic driven colloidal robot system in Chapter 5, which could show navigation behaviors (uphill and downhill) on a slope by rationally programming the external magnetic field. Chapter 6 highlights future research directions and potential applications of colloidal robots.

description: The FeSe nematic phase has been the focus of recent research on iron based superconductors (IBSs) due to its unique properties. A number of electronic structure studies were performed to find the origin of the phase. However, such attempts came out with conflicting results and caused additional controversies. Here, we report results from angle resolved photoemission and X-ray absorption spectroscopy studies on FeSe with detwinning by a piezo stack. We have fully resolved band dispersions with orbital characters near the Brillouin zone corner which reveals absence of a Fermi pocket at the Y point in the 1Fe Brillouin zone. In addition, the occupation imbalance between dxz and dyz orbitals is found to be opposite to that of iron pnictides, which is consistent with the identified band characters. These results settle down controversial issues in the FeSe nematic phase and shed light on the origin of nematic phases in IBSs.

description: In the present decade, social media is taking over as a large ubiquitous platform to access and disseminate news. While some are official news sources, a majority of accounts on Online Social Networks are indulged into sharing fake news. Social media comprises of a large set of information which users can readily access to. The reliability of posts that user access, absorb and share is not well specified. In this paper, we review the transmission of fake news on multiple Online Social Networks (OSNs). We consider three most used social networks in the current era: Twitter, Facebook and Instagram. We study i) fake news taxonomy, actors and impacts, ii) how fake news radiates on social media, iii) nature of fake news on multiple platforms, iv) how multiple networks can be inter-related to check fake news and v) how propagation and detection works on each OSN individually. We have presented fake news statistics, taxonomies, exposure on social media, current trends on prevention and detection of fake news on multiple social media platforms. We have also discussed ways to limit the radiation of fake news.

description: Background and Objectives: Brain tumors in the ventricular system are rare lesions whose surgical removal is very challenging due to their localization in the depth of the brain and their adjacency to eloquent brain areas. Over the decades, different surgical techniques have been developed with advantages and disadvantages depending on tumor location, planning, and execution. To date, few studies have compared the two most commonly used surgical access routes in terms of peri- and postoperative complications and quality of life. Therefore, the aim of this study is to assess long-term results of the transcortical compared with the transcallosal surgical technique for microsurgical resection of tumors in the ventricular system. Hereby, tumor control, safety of surgical procedures, and effects on neurological functions and quality of life of patients will be analyzed.

description: We present a new computed tomography (CT) method for inverting the Radon transform in 2D. The idea relies on the geometry of the flat torus, hence we call the new method Torus CT. We prove new inversion formulas for integrable functions, solve a minimization problem associated to Tikhonov regularization in Sobolev spaces and prove that the solution operator provides an admissible regularization strategy with a quantitative stability estimate. This regularization is a simple post-processing low-pass filter for the Fourier series of a phantom. We also study the adjoint and the normal operator of the X-ray transform on the flat torus. The X-ray transform is unitary on the flat torus. We have implemented the Torus CT method using Matlab and tested it with simulated data with promising results. The inversion method is meshless in the sense that it gives out a closed form function that can be evaluated at any point of interest.

description: Hintergrund Die Resektion bösartiger Thoraxwandtumoren (TWTs) stellt für den Thorax- und plastisch-rekonstruktiven Chirurgen eine große Herausforderung dar. Ziel dieser Studie war es, die perioperativen Ergebnisse und das Gesamtüberleben (GÜ) nach Resektionen von primären und sekundären TWT zu untersuchen. Materialien und Methoden Alle Patienten in der Zeitspanne von 2000 bis 2019, die aufgrund TWTs chirurgisch behandelt wurden, wurden retrospektiv analysiert. Ergebnisse Untersucht wurden 42 Patienten (25 männlich, Medianalter 60 J), die in kurativer (N=37, 88.1%) oder palliativer (N=5, 11.9%) Absicht behandelt wurden. 33 (78%) TWTs waren sekundären Ursprungs. Die Thoraxwandrekonstruktion war in 40 (95%) Fällen notwendig. Bei 13 (31%) Patienten traten postoperative Komplikationen auf. 1 (2,3 %) Patient verstarb perioperativ. Die 5-Jahres-Überlebensrate (5JÜR) betrug 51.9%. Bei Patienten mit primären TWTs war die 5JÜR mit 87,5% höher als die der Patienten mit sekundären TWTs, welche 42,6% betrug. Schlussfolgerung Bei gut ausgewählten Patienten ist die interdisziplinäre chirurgische Behandlung der primären und sekundären TWT sinnvoll und mit guten postoperativen Ergebnissen assoziiert. Bei sekundären TWTs kann die Resektion auch in palliativer Absicht durchgeführt werden.

description: Statements about relativistic effects are often subtle. In this essay we will demonstrate that the three classical tests of general relativity, namely perihelion precession, deflection of light and gravitational redshift, are passed perfectly by an extension of Newtonian gravity that includes gravitational time dilation effects while retaining a non-relativistic causal structure. This non-relativistic gravity theory arises from a covariant large speed of light expansion of Einstein's theory of gravity that does not assume weak fields and which admits an action principle.

description: A convenient and general decomposition of the photon self-energy in a magnetized, but otherwise isotropic, medium is given in terms of the minimal set of tensors consistent with the transversality condition. As we show, the self-energy in such a medium is completely parametrized in terms of nine independent form factors, and they reduce to three in the long wavelength limit. We consider in detail an electron gas with a background magnetic field, and using finite temperature field theory methods, we obtain the one-loop formulas for the form factors, which are exact to all orders in the magnetic field. Explicit results are derived for a variety of physical conditions. In the appropriate limits, we recover the well-known semi-classical results for the photon dispersion relations and the Faraday effect. In more general cases, where the semi-classical treatment or the linear approximation (weak field limit) are not applicable, our formulas provide a consistent and systematic way for computing the self-energy form factors and, from them, the photon dispersion relations.

Waveguide Modes in Weyl Semimetals with Tilted Dirac Cones

description: We theoretically study unattenuated electromagnetic guided wave modes in centrosymmetric Weyl semimetal layered systems. By solving Maxwell's equations for the electromagnetic fields and using the appropriate boundary conditions, we derive dispersion relations for propagating modes in a finite-sized Weyl semimetal. Our findings reveal that for ultrathin structures, and proper Weyl cones tilts, extremely localized guided waves can propagate along the semimetal interface over a certain range of frequencies. This follows from the anisotropic nature of the semimetal where the diagonal components of the permittivity can exhibit a tunable epsilon-near-zero response. From the dispersion diagrams, we determine experimentally accessible regimes that lead to high energy-density confinement in the Weyl semimetal layer. Furthermore, we show that the net system power can vanish all together, depending on the Weyl cone tilt and frequency of the electromagnetic wave.These effects are seen in the energy transport velocity, which demonstrates a substantial slowdown in the propagation of electromagnetic energy near critical points of the dispersion diagrams. Our results can provide guidelines in designing Weyl semimetal waveguides that can offer efficient control in the velocity and direction of energy flow.

description: The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional theory calculations, we determine the spin polarization of the surface bands of Sb(110). The existence of the unconventional spin texture is corroborated by the investigations of the electron scattering on this surface. The charge interference patterns formed around single scattering impurities, imaged by scanning tunneling microscopy, reveal the absence of direct backscattering signal. We identify the allowed scattering vectors and analyze their bias evolution in relation to the surface-state dispersion.
Learning time-stepping by nonlinear dimensionality reduction to predict magnetization dynamics

description: We establish a time-stepping learning algorithm and apply it to predict the solution of the partial differential equation of motion in micromagnetism as a dynamical system depending on the external field as parameter. The data-driven approach is based on nonlinear model order reduction by use of kernel methods for unsupervised learning, yielding a predictor for the magnetization dynamics without any need for field evaluations after a data generation and training phase as precomputation. Magnetization states from simulated micromagnetic dynamics associated with different external fields are used as training data to learn a low-dimensional representation in so-called feature space and a map that predicts the time-evolution in reduced space. Remarkably, only two degrees of freedom in feature space were enough to describe the nonlinear dynamics of a thin-film element. The approach has no restrictions on the spatial discretization and might be useful for fast determination of the response to an external field.

description: This paper explores the field of object detection in computer vision, specifically focusing on the identification of flying birds in images and videos. Utilizing the OpenCV library, the study implements two distinct methodologies: Haar Cascade Classifiers, a traditional yet efficient approach for object detection, and the Single Shot Multi-Box Detector (SSD), a deep learning-based technique known for its real-time accuracy and speed. By comparing these two methods, this research presents a comprehensive framework for detecting birds in flight. The Haar Cascade Classifier provides a lightweight, rule-based detection mechanism, while the SSD model, leveraging deep neural networks, enhances precision and robustness. The proposed hybrid approach aims to improve detection accuracy in dynamic environments, making it applicable to wildlife monitoring, avian migration studies, and ecological research.

description: In general, standard necessary optimality conditions cannot be formulated in a straightforward manner for semi-smooth shape optimization problems. In this paper, we consider shape optimization problems constrained by variational inequalities of the first kind, so-called obstacle-type problems. Under appropriate assumptions, we prove existence of adjoints for regularized problems and convergence to limiting objects of the unregularized problem. Moreover, we derive existence and closed form of shape derivatives for the regularized problem and prove convergence to a limit object. Based on this analysis, an efficient optimization algorithm is devised and tested numerically.
