description: Accurate prediction of the natural frequency for the lateral oscillation of a liquid drop pinned on a vertical planar surface is important to many drop applications. The natural oscillation frequency, normalized by the capillary frequency, is {mainly} a function of the equilibrium contact angle and the Bond number (Bo), when the contact lines remain pinned. Parametric numerical and experimental studies have been performed to establish a comprehensive understanding of oscillation dynamics. {An} inviscid model has been developed to predict the oscillation frequency for wide ranges of Bo and contact angles. The model reveals the scaling relation between the normalized frequency and Bo, which is validated by the numerical simulation results. For a given equilibrium contact angle, the lateral oscillation frequency decreases with Bo, implying that resonance frequencies will be magnified if the drop oscillations occur in a reduced gravity environment.

Impact of inlet gas turbulence on the formation, development and breakup of interfacial waves in a two-phase mixing layer

description: Understanding the development and breakup of interfacial waves in a two-phase mixing layer between the gas and liquid streams is paramount to atomization. Due to the velocity difference between the two streams, the shear on the interface triggers a longitudinal instability, which develops to interfacial waves that propagate downstream. As the interfacial waves grow spatially, transverse modulations arise, turning the interfacial waves from quasi-2D to fully 3D. The inlet gas turbulence intensity has a strong impact on the interfacial instability. Therefore, parametric direct numerical simulations are performed in the present study to systematically investigate the effect of the inlet gas turbulence on the formation, development, and breakup of the interfacial waves. The open-source multiphase flow solver, PARIS, is used for the simulations and the mass-momentum consistent volume-of-fluid method is used to capture the sharp gas-liquid interfaces. Two computational domain widths are considered and the wide domain will allow a detailed study of the transverse development of the interfacial waves. The dominant frequency and spatial growth rate of the longitudinal instability are found to increase with the inlet gas turbulence intensity. The dominant transverse wavenumber, determined by the Rayleigh-Taylor instability, scales with the longitudinal frequency, so it also increases with the inlet gas turbulence intensity. The holes formed in the liquid sheet is important to the disintegration of the interfacial waves. The holes formation is influenced by the inlet gas turbulence. As a result, the sheet breakup dynamics and the statistics of the droplets formed also change accordingly.

description: Der aus Zürich stammende Johann Jakob Scheuchzer (1672–1733) erhielt die Prägungen für seine naturkundlichen Forschungen und Veröffentlichungen im Umfeld der fränkischen Handelsmetropole Nürnberg und ihrer Universität Altdorf. Hier gelang es ihm, Kontakte zu knüpfen, die ihm später den Ausbau eines Briefwechselnetzes ermöglichten. Dadurch konnte er zu einem weithin bekannten Gelehrten, vor allem in der Fossilienkunde, werden. Besondere Bedeutung für diese Kontakte hatte die Naturforscherakademie Leopoldina, der Scheuchzer seit 1697 angehörte. Obwohl seine ärztliche Karriere in Zürich zunächst hinter seinen Erwartungen zurückblieb, glückte es ihm doch, vorerst ein regionales Netzwerk mit Gelehrten in der Stadt zu einem überregionalen Gelehrtennetzwerk der Schweiz auszubauen und schließlich auch in das Reich und das weitere Ausland zu erweitern.
description: Johann Jakob Scheuchzer (1672–1733) was born in Zurich and received the coins for his scientific research and publications around the Franconian commercial metropolis of Nuremberg and its University of Altdorf. Here he was able to establish contacts, which later enabled him to expand a network of correspondence exchanges. This enabled him to become a well-known scholar, especially in the field of fossil science. The Leopoldina Academy of Natural Sciences, of which Scheuchzer had been a member since 1697, was particularly important for these contacts. Although his medical career in Zurich initially fell short of his expectations, he nevertheless managed to expand a regional network of scholars in the city into a supraregional network of scholars in Switzerland and eventually to expand it into the Reich and beyond.

description: Soft materials (e.g., enveloped viruses, liposomes, membranes and supercooled liquids) simultaneously deform or display collective behaviors, while undergoing atomic scale vibrations and collisions. While the multiple space-time character of such systems often makes traditional molecular dynamics simulation impractical, a multiscale approach has been presented that allows for long-time simulation with atomic detail based on the co-evolution of slowly-varying order parameters (OPs) with the quasi-equilibrium probability density of atomic configurations. However, this approach breaks down when the structural change is extreme, or when nearest-neighbor connectivity of atoms is not maintained. In the current study, a self-consistent approach is presented wherein OPs and a reference structure co-evolve slowly to yield long-time simulation for dynamical soft-matter phenomena such as structural transitions and self assembly. The development begins with the Liouville equation for N classical atoms and an ansatz on the form of the associated N-atom probability density. Multiscale techniques are used to derive Langevin equations for the coupled OP configurational dynamics. The net result is a set of equations for the coupled stochastic dynamics of the OPs and centers of mass of the subsystems that constitute a soft material body. The theory is based on an all-atom methodology and an interatomic force field, and therefore enables calibration-free simulations of soft matter, such as macromolecular assemblies.

Numerical study of natural oscillations of supported drops with free and pinned contact lines

Year: 2023
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: In the present study, the axisymmetric natural oscillations of a liquid drop supported by a flat surface is investigated by direct numerical simulation. The liquid-gas interface is captured using a geometric volume-of-fluid (VOF) method. A parametric study is carried out by varying the equilibrium contact angle and the gravitational Bond number (Bo). Both positive and negative gravities are considered, and thus the results cover both pendant and sessile drops. To incorporate the effect of contact line mobility, the two asymptotic limits, namely the pinned contact line (PCL) and free contact line (FCL) conditions, are considered and their effects on the drop oscillation features are characterized. The predicted oscillation frequencies for PCL and FCL serve as the upper and lower bounds for general situations. The drop oscillation is initiated by increasing the gravity magnitude for a short time. The first mode due to the drop centroid translation dominates the excited oscillation. The oscillation frequency scales with the capillary frequency, and the normalized frequency monotonically decreases with the equilibrium contact angle. For zero gravity, the computed frequencies for all contact angles agree remarkably well with the inviscid theory for both the PCL and FCL conditions. The kinetic energy correction factor is introduced to account for the additional contribution of the oscillation-induced internal flow to the overall kinetic energy of the drop. Both the frequency and the kinetic energy correction factor increase with Bo, decrease with the contact angle, and increase when the contact line condition changed from FCL to PCL. The variation of oscillation frequency due to the change of Bo is particularly significant when the contact angle is large.

description: A standard multimode optical fiber can be used as a general purpose spectrometer after calibrating the wavelength dependent speckle patterns produced by interference between the guided modes of the fiber. A transmission matrix was used to store the calibration data and a robust algorithm was developed to reconstruct an arbitrary input spectrum in the presence of experimental noise. We demonstrate that a 20 meter long fiber can resolve two laser lines separated by only 8 pm. At the other extreme, we show that a 2 centimeter long fiber can measure a broadband continuous spectrum generated from a supercontinuum source. We investigate the effect of the fiber geometry on the spectral resolution and bandwidth, and also discuss the additional limitation on the bandwidth imposed by speckle contrast reduction when measuring dense spectra. Finally, we demonstrate a method to reduce the spectrum reconstruction error and increase the bandwidth by separately imaging the speckle patterns of orthogonal polarizations. The multimode fiber spectrometer is compact, lightweight, low cost, and provides high resolution with low loss.

Entanglement Classification of extended Greenberger-Horne-Zeilinger-Symmetric States

Year: 2013
Subjects: subject: Quantum Physics (quant-ph)

description: In this paper we analyze entanglement classification of extended Greenberger-Horne-Zeilinger-symmetric states $ρ^{ES}$, which is parametrized by four real parameters $x$, $y_1$, $y_2$ and $y_3$. The condition for separable states of $ρ^{ES}$ is analytically derived. The higher classes such as bi-separable, W, and Greenberger-Horne-Zeilinger classes are roughly classified by making use of the class-specific optimal witnesses or map from the extended Greenberger-Horne-Zeilinger symmetry to the Greenberger-Horne-Zeilinger symmetry. From this analysis we guess that the entanglement classes of $ρ^{ES}$ are not dependent on $y_j \hspace{.2cm} (j=1,2,3)$ individually, but dependent on $y_1 + y_2 + y_3$ collectively. The difficulty arising in extension of analysis with Greenberger-Horne-Zeilinger symmetry to the higher-qubit system is discussed.

description: 1670 gab die Academia naturae curiosorum den ersten Band der Miscellanea curiosa heraus. Im Gegensatz zu anderen Zeitschriften konzentrierten sich die Miscellanea von Anfang an auf Medizin und Naturforschung. Ihr Ziel war, die Kommunikation von Wissen innerhalb und außerhalb der Akademie zu fördern. Hierfür griff man das bereits etablierte Textgenre der Beobachtung (observatio) auf, kommentierte aber die Beiträge zuweilen auch in einer Weise, die zuvor nicht üblich war. Vor allem Letzteres führte wiederholt zu Kritik von Seiten der Autoren. Änderungen am Konzept der Zeitschrift wurden jedoch von den jeweiligen Herausgebern und Akademiepräsidenten abgelehnt. Dass die Herausgeberschaft letztlich zu einer Machtposition geworden war, zeigen auch die Konflikte zwischen den Herausgebern und dem Präsidenten.

In contrast to other journals the Miscellanea focused on medicine and natural sciences right from the start. It aimed at stimulating the communication of knowledge inside and outside of the academy. For this the editors made use of the established text genre of observations but also commented the contributions in a way, which was uncommon at the time. This lead to repeated criticism from the authors, but changes in the concept of the journal were refuted by the respective editors and academy presidents. Editorship had developed into a powerful position, which is also visible in the conflicts between the editors and the president.

description: We report on the identification of the optical counterpart to the recently detected INTEGRAL transient IGR J18245-2452 in the Galactic globular cluster M28. From the analysis of a multi epoch HST dataset we have identified a strongly variable star positionally coincident with the radio and Chandra X-ray sources associated to the INTEGRAL transient. The star has been detected during both a quiescent and an outburst state. In the former case it appears as a faint, unperturbed main sequence star, while in the latter state it is about two magnitudes brighter and slightly bluer than main sequence stars. We also detected Halpha excess during the outburst state, suggestive of active accretion processes by the neutron star.

description: Understanding human neuromechanics is the first step in transforming human capabilities and behaviour into smart human-like robotic systems. The aim of this thesis is to develop a human hand neuromusculoskeletal model that serves as a tool in understanding and replicating human behaviour. In this thesis, five models of the human hand are proposed, i.e. skeletal kinematics, skeletal dynamics, musculotendon kinematics, musculotendon dynamics, and muscle activation estimation. The skeletal kinematic model is a 26 degree of freedom model that includes the five digits and the palm arc. It estimates skeletal joint rotational angles from motion tracking data based on mapping functions between surface landmarks and the estimated joint centres of rotation. In the skeletal dynamic model, both the link torque due to gravitational and inertial forces and the passive torque due to the passive joint properties are estimated. The musculotendon kinematic model calculates musculotendon lengths, length change rates, and musculotendon excursion moment arms as a function of joint configuration. The musculotendon dynamic model used is a Hill-type muscle model that predicts the musculotendon forces for given musculotendon lengths, length change rates, and muscle activations. The musculotendon length and its rate of change are obtained from the proposed musculotendon kinematic model while muscle activations are obtained from the proposed muscle activation estimation model. Using this model, muscle activations are optimised by minimising the difference between the torque resulting from the musculotendon dynamic model and skeletal dynamic model. The proposed models were validated either experimentally using a motion tracking system or by comparing model results with available cadaver/experimental measurements taken from the literature. The sub-millimetre difference between measured and estimated surface markers indicates that the proposed skeletal kinematic model and associated identification procedure are consistent and highly accurate. The high similarity (similarity coefficient s ≥ 0.70 for 92% of cases) shown between the modelled moment arms and available cadaver measurements from the literature suggests the correctness of the modelled moment arms, and implies the feasibility of the modelled musculotendon paths, lengths, and length change rates. Finally, the overall consistency between the five models proposed will be demonstrated and highlights the quality of the developed models.

description: During the process of photosynthesis plants fix atmospheric CO2 into organic carbohydrates. The photosynthetic assimilation rates resulting from this reaction differ among different photosynthetic variants, in which C3 photosynthesis represents the most simple and ancestral photosynthetic variant, whereas C4 is the more advanced variant and more correlated with increased biomass. C4 photosynthesis evolved more than 60 times independently via intermediate C3-C4 variants that are referred to as C2 photosynthesis and are considered as a bridge between C3 and C4 photosynthesis. Understanding of the molecular basis of the evolution of C4 holds the potential of improving crop productivity. This thesis is mainly concerned with one of the earliest steps of development of the C4-trait, the restriction of glycine decarboxylase (GDC) complex to the bundle sheath (BS) of C2 plants. By using promoter deletion experiments this work shows that restriction of the GDC to the BS of C3 plants is possible. The cis-element responsible for this spatial expression was isolated from the promoter of AtGldp1, one of the two genes encoding the GDC-P subunit in Arabidopsis thaliana. The identified element is referred to as the M-box. Using bioinformatic analysis this work generalizes the presence of the M-box in the promoters of most C3 Gldp1 genes from Brassicaceae and suggests its loss from promoters of most C2 Gldp genes. Subsequently, this offers a possible molecular mechanism for restriction of GDC to BS in at least in genus Moricandia. The bioinformatic analysis was further validated experimentally by isolating additional C3 and C2 promoters from other species of the Moricandia that were not characterized or isolated before by restriction genome walking. We show that the M-box is found in the promoter of a C3 Moricandia species and absent in three Gldp promoters for three different Moricandia C2 species. The isolated promoters were further studied in Arabidopsis. Furthermore the M-box binding factor was defined to be a member of GATA transcription factor family via a yeast-one-hybrid screening coupled with several coexpression analyses and the processing of previous genome-wide footprint sequencing data. Collective results from this study identify and characterize a simple mechanism for establishing C2-specific gene expression in a C3 plant like Arabidopsis.

subject: failure modes

description: Purpose: The quantitative detection of failure modes is important for making deep neural networks reliable and usable at scale. We consider three examples for common failure modes in image reconstruction and demonstrate the potential of uncertainty quantification as a fine-grained alarm system. Methods: We propose a deterministic, modular and lightweight approach called Interval Neural Network (INN) that produces fast and easy to interpret uncertainty scores for deep neural networks. Importantly, INNs can be constructed post hoc for already trained prediction networks. We compare it against state-of-the-art baseline methods (MCDrop, ProbOut). Results: We demonstrate on controlled, synthetic inverse problems the capacity of INNs to capture uncertainty due to noise as well as directional error information. On a real-world inverse problem with human CT scans, we can show that INNs produce uncertainty scores which improve the detection of all considered failure modes compared to the baseline methods. Conclusion: Interval Neural Networks offer a promising tool to expose weaknesses of deep image reconstruction models and ultimately make them more reliable. The fact that they can be applied post hoc to equip already trained deep neural network models with uncertainty scores makes them particularly interesting for deployment.
Strain tuning of a quantum dot strongly coupled to a photonic crystal cavity

description: We demonstrate reversible strain-tuning of a quantum dot strongly coupled to a photonic crystal cavity. We observe an average redshift of 0.45 nm for quantum dots located inside the cavity membrane, achieved with an electric field of 15 kV/cm applied to a piezo-electric actuator. Using this technique, we demonstrate the ability to tune a quantum dot into resonance with a photonic crystal cavity in the strong coupling regime, resulting in a clear anti-crossing. The bare cavity resonance is less sensitive to strain than the quantum dot and shifts by only 0.078 nm at the maximum applied electric field.

Stopping Methods for Technology Assisted Reviews based on Point Processes
Creators: name: Stevenson, Mark
name: Bin-Hezam, Reem
Publisher: name: arXiv
Year: 2023
Subjects: subject: Information Retrieval (cs.IR)
subject: FOS: Computer and information sciences

description: Technology Assisted Review (TAR), which aims to reduce the effort required to screen collections of documents for relevance, is used to develop systematic reviews of medical evidence and identify documents that must be disclosed in response to legal proceedings. Stopping methods are algorithms which determine when to stop screening documents during the TAR process, helping to ensure that workload is minimised while still achieving a high level of recall. This paper proposes a novel stopping method based on point processes, which are statistical models that can be used to represent the occurrence of random events. The approach uses rate functions to model the occurrence of relevant documents in the ranking and compares four candidates, including one that has not previously been used for this purpose (hyperbolic). Evaluation is carried out using standard datasets (CLEF e-Health, TREC Total Recall, TREC Legal), and this work is the first to explore stopping method robustness by reporting performance on a range of rankings of varying effectiveness. Results show that the proposed method achieves the desired level of recall without requiring an excessive number of documents to be examined in the majority of cases and also compares well against multiple alternative approaches.

Hamiltonian spinfoam gravity

Publisher: name: arXiv
Year: 2013
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This paper presents a Hamiltonian formulation of spinfoam-gravity, which leads to a straight-forward canonical quantisation. To begin with, we derive a continuum action adapted to the simplicial decomposition. The equations of motion admit a Hamiltonian formulation, allowing us to perform the constraint analysis. We do not find any secondary constraints, but only get restrictions on the Lagrange multipliers enforcing the reality conditions. This comes as a surprise. In the continuum theory, the reality conditions are preserved in time, only if the torsionless condition (a secondary constraint) holds true. Studying an additional conservation law for each spinfoam vertex, we discuss the issue of torsion and argue that spinfoam gravity may indeed miss an additional constraint. Next, we canonically quantise. Transition amplitudes match the EPRL (Engle--Pereira--Rovelli--Livine) model, the only difference being the additional torsional constraint affecting the vertex amplitude.

description: In this letter, following a cross-layer design concept, we propose a novel subcarrier grouping technique for Orthogonal Frequency and Code Division Multiplexing (OFCDM) multiuser systems. We adopt a two dimensional (2D) spreading, so as to achieve both frequency- and time-domain channel gain. Furthermore, we enable a receiver-centric approach, where the receiver rather than a potential sender controls the admission decision of the communication establishment. We study the robustness of the proposed scheme in terms of the Bit-Error-Rate (BER) and the outage probability. The derived results indicate that the proposed scheme outperforms the classical OFCDM approach.
