description: Decoherence often happens in the quantum world. We try to utilize quantum dephasing to build an optimal thermometry. By calculating the Cram$\acute{e}$r-Rao bound, we prove that the Ramsey measurement is the optimal way to measure the temperature for uncorrelated particles. Using the optimal measurement, the metrological equivalence of product and maximally entangled states of initial quantum probes that always holds. However, using Ramsey measurement, the metrological equivalence only holds in special situation. Contrary to frequency estimation, the quantum limit can be surpassed under the case $ν<1$. For the general Zeno regime($ν=2$), uncorrelated product states are the optimal choose in typical Ramsey spectroscopy set-up. In order to surpass the standard scaling, we propose to change the interaction strength with time. Finally, we investigate other environmental influences on the measurement precision of temperature. Base on it, we define a new way to measure non-Markovian effect.

Year: 2016

description: The main objective of this study is to investigate trends of land use/cover changes since the 1980s in Mandura district of Benshangul-Gumuz regional state. A total of 210 farm households from three kebeles: 105 from the local people and 105 from migrants were surveyed in May 2011 to acquire data on socioeconomic and land use. Aerial photographs of 1982 and SPOT-5 image of the 2006/07 were used to generate data on land use/cover changes. The results of this study indicate that respondents perceive that there were land use/cover changes in the study area since the 1990s. In view of this, respondents feel that bamboo trees, grazing land, grassland as well as wildlife have shown decline since the 1990s. The aerial photograph and spot-5 image analyses reveal the same result. Of the total 35, 386 ha of land that underwent conversion, farmland constituted 85.5%, riverine trees 12.4% and settlements 2.1%. The major drivers of land use/cover changes identified by respondents were population increase which in turn has triggered expansion of agriculture and deforestation. Consequently, the indigenous population has faced land shortage for practicing shifting cultivation. Furthermore, they were forced to change their livelihoods which in turn triggered natural environment degradation because of charcoal and wood selling practices. The study finally concludes that trends in land use/cover changes are evident and needs proper attention and appropriate interventions.

description: KÜMMEL, F. 2010: Plant and seed lists of the Botanical Garden of the University Halle since 1749. Schlechtendalia 20: 57–78. Plant and seed catalogues of botanical gardens are valuable sources, above all when they are very old. Unfortunately such catalogues have often not been maintained, so that complete collections are barely preserved anywhere. The Botanical Garden of the University Halle (Saale) may be considered the origin of annual seed catalogues since this tradition was initiated by Kurt Sprengel in 1797. Numerous data on seed catalogues have been found during the course of long standing research of the author on the history of the Botanical Garden Halle. In this paper, attempts have been made, as far as possible, to present an almost complete documentation on seed catalogues issued by the Botanical Garden of the University Halle (Saale). In order to enable an easy access for all who are interested in such catalogues, it is listed where each particular issue is preserved.

Conception of the volumes, system, standard-list and deviations, neophytes, terminology. Schlechtendalia 20: 79 – 89. The new basic volume of “Exkursionsflora von Deutschland” is prepared on the basis of vol. 4, 10th edition (2005). It includes most of the subspecies, but not the microspecies of Ranunculus auricomus agg., Taraxacum and only the most important ones of Sorbus and Rubus. The system is based on new proposals for the pteridophytes (Smith et al. 2006), gymnosperms and angiosperms (APG III, Stevens 2010). The nomenclature and selection of taxa will basically follow the new standard list of the flora of Germany (Buttler & Hand 2008). Deviations from this list will be discussed in the series “Comments”, in the present number for Jovibarba, Silene, Chamaesyce and Lavatera. Many neophytes are included, also not yet established ones, in order to control their possible invasion. Changes in the morphological terminology are discussed.

description: The next generation of space and ground-based solar missions aim to study the magnetic properties of the solar chromosphere using the infrared Ca II lines and the He I 10830 Å line. The former seem to be the best candidates to study the stratification of magnetic fields in the solar chromosphere and their relation to the other thermodynamical properties underlying the chromospheric plasma. The purpose of this work is to provide a detailed analysis of the diagnostic capabilities of the Ca II 8542 Å line, anticipating forthcoming observational facilities. We study the sensitivity of the Ca II 8542 Å line to perturbations applied to the physical parameters of reference semi-empirical 1D model atmospheres using response functions and we make use of 3D MHD simulations to examine the expected polarization signals for moderate magnetic field strengths. Our results indicate that the Ca II 8542 Å line is mostly sensitive to the layers enclosed between $\log$ $τ=[0,-5.5]$, under the physical conditions that are present in our model atmospheres. In addition, the simulated magnetic flux tube generates strong longitudinal signals in its centre and moderate transversal signals, due to the vertical expansion of magnetic field lines, in its edge. Thus, observing the Ca II 8542 Å line we will be able to infer the 3D geometry of moderate magnetic field regions.

Nach den Regeln des ICBN hat der Name Ceratoides em. Reveal & Holmgren eindeutig Priorität (REVEAL & HOLMGREN 1972). Da der Gattungsname Ceratoides jedoch wenig Beachtung findet und bei seiner Typisierung die historischen Fakten, die gegen Ceratoides sprechen, völlig unberücksichtigt blieben, wurde dem Nomenklatur-Komitee der Vorschlag zur Konservierung des Gattungsnamens Krascheninnikovia (HEKLAU 2006) unterbreitet. In diesem Artikel wird nun die Geschichte des unbeliebten Gattungsnamens Krascheninnikovia im Detail aufgezeigt.

The name Ceratoides, however, was rarely employed. Therefore and by reasons of the history of the generic name, Krascheninnikovia was proposed as a genus name to be conserved against Ceratoides (HEKLAU 2006).The fate of the unpopular generic name Krascheninnikovia in the botanic history is presented in detail.

description: Almost 50 years after the discovery of gluons & quarks, we are only just beginning to understand how QCD builds the basic bricks for nuclei: neutrons, protons, and the pions that bind them. QCD is characterised by two emergent phenomena: confinement & dynamical chiral symmetry breaking (DCSB). They are expressed with great force in the character of the pion. In turn, pion properties suggest that confinement & DCSB are closely connected. As both a Nambu-Goldstone boson and a quark-antiquark bound-state, the pion is unique in Nature. Developing an understanding of its properties is thus critical to revealing basic features of the Standard Model. We describe experimental progress in this direction, made using electromagnetic probes, highlighting both improvements in the precision of charged-pion form factor data, achieved in the past decade, and new results on the neutral-pion transition form factor. Both challenge existing notions of pion structure. We also provide a theoretical context for these empirical advances, first explaining how DCSB works to guarantee that the pion is unnaturally light; but also, nevertheless, ensures the pion is key to revealing the mechanisms that generate nearly all the mass of hadrons. Our discussion unifies the charged-pion elastic and neutral-pion transition form factors, and the pion's twist-2 parton distribution amplitude. It also indicates how studies of the charged-kaon form factor can provide significant contributions. Importantly, recent predictions for the large-$Q^2$ behaviour of the pion form factor can be tested by experiments planned at JLab 12. Those experiments will extend precise charged-pion form factor data to momenta that can potentially serve in validating factorisation theorems in QCD, exposing the transition between the nonperturbative and perturbative domains, and thereby reaching a goal that has long driven hadro-particle physics.

description: With an annual production amounting to 800 kilotons, ferrite magnets constitute the largest family of permanent magnets in volume, a demand that will only increase as a consequence of the rare-earth crisis. With the global goal of building a climate-resilient future, strategies towards a greener manufacturing of ferrite magnets are of great interest. A new ceramic processing route for obtaining dense Sr-ferrite sintered magnets is presented here. Instead of the usual sintering process employed nowadays in ferrite magnet manufacturing that demands long dwell times, a shorter two-step sintering is designed to densify the ferrite ceramics. As a result of these processes, dense SrFe$_{12}$O$_{19}$ ceramic magnets with properties comparable to state-of-the-art ferrite magnets are obtained. In particular, the SrFe$_{12}$O$_{19}$ magnet containing 0.2% PVA and 0.6% wt SiO$_2$ reaches a coercivity of 164 kA/m along with a 93% relative density. A reduction of 31% in energy consumption is achieved in the thermal treatment with respect to conventional sintering, which could lead to energy savings for the industry of the order of 7.109 kWh per year.

description: Upon loading, atomic networks can feature delayed viscoplastic relaxation. However, the effect of composition and structure on such a relaxation remains poorly understood. Herein, relying on accelerated molecular dynamics simulations and topological constraint theory, we investigate the relationship between atomic topology and stress-induced relaxation, by taking the example of creep deformations in calcium--silicate--hydrates, the binding phase of concrete. Under constant shear stress, C--S--H is found to feature delayed logarithmic shear deformations. We demonstrate that the propensity for relaxation is minimum for isostatic atomic networks, which are characterized by the simultaneous absence of floppy internal modes of relaxation and eigen stress. This suggests that topological nano-engineering could lead to the discovery of non-aging materials.

Year: 2023

description: We present a simple framework to support sharing of executable healthcare discrete-event simulation models in python over the web. Our sharing framework is based on combining remote version control repositories with free and open source software - Jupyter Notebooks, Jupyter Books, and streamlit - along with free digital infrastructure provided by Binder, streamlit.io, GitHub pages, and open science repositories such as Zenodo. The framework enables executable models to be shared with users of different technical abilities: from coders to software literate users. We provide an applied example including a full web application of an executable model. Our framework aims to support NHS organisations to preview, validate, and use models. Academic research teams can also benefit from enhanced scrutiny of their work and long term archiving of models.

description: AI accelerators have proliferated in data centers in recent years and are now almost ubiquitous. In addition, their computational power and, most importantly, their energy efficiency are up to orders of magnitude higher than that of traditional computing. Over the last years, various methods and optimizations have been tested to use these hybrid systems for simulations in the context of astroparticle physics utilizing CORSIKA. The main focus of this talk is the propagation of optical, i.e. fluorescence and Cherenkov, photons through low density inhomogeneous media in the context of the next generation CORSIKA8 simulation framework. Different techniques used and approximations, e.g. the atmospheric model, tested during the development will be presented. The trade-off between performance and precision allows the experiment to achieve its physical precision limited to the real resolution of the experiment and not invest power and time in vanishing precision gains. The additional comparison of classical CPU-based simulations with the new methods validates these methods and allows evaluation against a known baseline.

description: We study the finite time singularity correspondence between the Jordan and Einstein frames for various $F(R)$ gravity theories. Particularly we investigate the ordinary pure $F(R)$ gravity case and the unimodular $F(R)$ gravity cases, in the absence of any matter fluids. In the ordinary $F(R)$ gravity cases, by using specific illustrative examples, we show that it is possible to have various correspondences of finite time singularities, and in some cases it is possible a singular cosmology in one frame might be non-singular in the other frame. In the unimodular $F(R)$ gravity case, the unimodular constraint is affected from the conformal transformation, so this has an effect on the metric we choose. Moreover, we study the Einstein frame counterpart theory of the unimodular $F(R)$ gravity case, and we investigate the correspondences of the singularities in the two theories by considering specific illustrative examples. Finally, a brief dynamical system analysis is performed for the vacuum unimodular $F(R)$ gravity and we demonstrate how the dynamical system behaves near the future Big Rip singularity.

The Botanical Garden of the University Wittenberg existed between 1660 and 1817, when the University Wittenberg and the University Halle were merged as new “Vereinigte Friedrichs-Universität Halle-Wittenberg“ in Halle. A complete docu- mentation of its history does not exist. A detailed evaluation of numerous catalogues of this garden from the first half of the 18th century led to surprising results, which force to a revision of some facts that have hitherto been regarded to be established. During the course of its existence of about 150 years, the former Hortus medicus in Wittenberg had been rather successful, at least partly, above all under H. Heucher and A. Vater as directors. On the other hand, it was also subjected to long periods of stagnation. In 1711, J.H. Heucher issued the first catalogue of plant (“Index plantarum horti medici academiae Vitembergensis“).

description: Understanding, predicting and controlling laminar-turbulent boundary-layer transition is crucial for the next generation aircraft design. However, in real flight experiments, or wind tunnel tests, often only sparse sensor measurements can be collected at fixed locations. Thus, in developing reduced models for predicting and controlling the flow at the sensor locations, the main challenge is in accounting for how the surrounding field of unobserved variables interacts with the observed variables at the fixed sensor locations. This makes the Mori-Zwanzig (MZ) formalism a natural choice, as it results in the Generalized Langevin Equations which provides a framework for constructing non-Markovian reduced-order models that includes the effects the unresolved variables have on the resolved variables. These effects are captured in the so called memory kernel and orthogonal dynamics. In this work, we explore the data-driven MZ formulations to two boundary layer flows obtained from DNS data; a low speed incompressible flow; and a high speed compressible flow over a flared cone at Mach 6. An array of "sensors" are placed near the surface of the solid boundary, and the MZ operators are learned and the predictions are compared to the Extended Dynamic Mode Decomposition (EDMD), both using delay embedded coordinates. Further comparisons are made with Long Short-Term Memory (LSTM) and a regression based projection framework using neural networks for the MZ operators. First we compare the effects of including delay embedded coordinates with EDMD and Mori based MZ and provide evidence that using both memory and delay embedded coordinates minimizes generalization errors on the relevant time scales. Next, we provide numerical evidence that the data-driven regression based projection MZ model performs best with respect to the prediction accuracy (minimum generalization error) on the relevant time scales.

Schlechtendalia 24: 53 –71.Das mehrteilige Werk „Botanica in originali“ von J.H. Kniphof erschien zunächst 1733 bis 1736 in Erfurt, ehe es von 1757 bis 1764 in Halle völlig neu gedruckt wurde. Dabei handelte es sich um die Abbildung von Pflanzenteilen durch die Methode des Naturselbstdruckes. Während die Erfurter Edition in der Vergangenheit bereits sehr ausführlich vorgestellt wurde, fehltebisher eine gründliche Darstellung der halleschen Ausgabe. Die intensive Beschäftigung mit einigen erhaltenen Exemplaren und deren Vergleich erbrachte neben einigen bemerkenswerten Details auch interessante Informationen zur Wissenschafts-geschichte und zur Floristik des halleschen Raumes.
description: KÜMMEL, F. 2012: The Halle issue of “Botanica in originali” (natural self-prints) by J.H. Kniphof. Schlechtendalia 24: 53 –71. J.H. Kniphof’s work “Botanica in originali”, comprising several volumes, was originally published between 1733 and 1736 in Erfurt, and later between 1757 and 1764 in Halle as completely new edition. This work comprises illustrations of plant parts produced by the natural self-print method. The edition published in Erfurt has previously already been presented in detail, but a similarly careful documentation of the edition from Halle is still lacking. Careful examinations and comparisons ofseveral maintained copies revealed some remarkable details as well as interesting information with regard to the scientific history and botanical exploration of the area around Halle.

description: We use the large cosmological hydro-dynamic simulation BlueTides to predict the photometric properties of galaxies during the epoch of reionisation ($z=8-15$). These properties include the rest-frame UV to near-IR broadband spectral energy distributions, the Lyman continuum photon production, the UV star formation rate calibration, and intrinsic UV continuum slope. In particular we focus on exploring the effect of various modelling assumptions, including the assumed choice of stellar population synthesis model, initial mass function, and the escape fraction of Lyman continuum photons, upon these quantities. We find that these modelling assumptions can have a dramatic effect on photometric properties leading to consequences for the accurate determination of physical properties from observations. For example, at $z=8$ we predict that nebular emission can account for up-to $50\%$ of the rest-frame $R$-band luminosity, while the choice of stellar population synthesis model can change the Lyman continuum production rate up to a factor of $\times 2$.

description: The classical electrodynamic two-body problem has been a long standing open problem in mathematics. For motion constrained to the straight line, the interaction is similar to that of the two-body problem of classical gravitation. The additional complication is the presence of unbounded state-dependent delays in the Coulomb forces due to the finiteness of the speed of light. This circumstance renders the notion of local solutions meaningless, and therefore, straight-forward ODE techniques can not be applied. Here, we study the time-symmetric case, i.e., the Fokker-Schwarzschild-Tetrode (FST) equations, comprising both advanced and retarded delays. We extend the technique developed in \cite{DirkGuenter}, where existence of FST solutions was proven on the half-line, to ensure global existence -- a result that had been obtained by Bauer \cite{Bauer} in 1997. Due to the novel technique, the presented proof is shorter and more transparent but also relies on the idea to employ asymptotic data to characterize solutions.

description: In today's interconnected globe, moving abroad is more and more prevalent, whether it's for employment, refugee resettlement, or other causes. Language difficulties between natives and immigrants present a common issue on a daily basis, especially in medical domain. This can make it difficult for patients and doctors to communicate during anamnesis or in the emergency room, which compromises patient care. The goal of the HYKIST Project is to develop a speech translation system to support patient-doctor communication with ASR and MT. ASR systems have recently displayed astounding performance on particular tasks for which enough quantities of training data are available, such as LibriSpeech. Building a good model is still difficult due to a variety of speaking styles, acoustic and recording settings, and a lack of in-domain training data. In this thesis, we describe our efforts to construct ASR systems for a conversational telephone speech recognition task in the medical domain for Vietnamese language to assist emergency room contact between doctors and patients across linguistic barriers. In order to enhance the system's performance, we investigate various training schedules and data combining strategies. We also examine how best to make use of the little data that is available. The use of publicly accessible models like XLSR-53 is compared to the use of customized pre-trained models, and both supervised and unsupervised approaches are utilized using wav2vec 2.0 as architecture.

description: A detailed investigation was carried out to understand a prolonged (~44 hours) weakly southward interplanetary magnetic field (IMF-Bz) condition during May 02--04, 1998. In-situ observations, during the period, showed the passage of an expanding magnetic cloud embedded in an interplanetary coronal mass ejection (ICME), followed up by a shock and an interplanetary discontinuity driven by another ICME. It is the arrival of the ICMEs and the upfront shocks that cause the prolonged southward IMF-Bz condition. The magnetic configuration of the source regions of the IMF associated with the ICME interval were also examined, which showed open magnetic field structures, emanating from a small active region on the north of the heliospheric current sheet (HCS). The structures remained constantly to the north of the HCS, both on April 29 and May 01, suggesting no change in their polarity. The draping of these outward directed radial field lines around the propagating CMEs in the shocked plasma explained the observed polarity changes of the IMF-Bz at 1 AU. In addition, multiple enhancements were also detected in the geomagnetic field variations, which showed a distinct one-to-one correspondence with the density pulses observed at 1 AU, during 0700--1700 UT on May 03. The spectral analysis of both the variations showed the same discrete frequencies of 0.48, 0.65 and 0.75 mHz, demonstrating that the solar wind density enhancements can cause detectable global geomagnetic disturbances. The observations, thus, provide a deeper insight into the possible causes and geomagnetic consequences of a prolonged weakly southward IMF-Bz condition.

description: Anthropomimetic robots are robots that sense, behave, interact and feel like humans. By this definition, anthropomimetic robots require human-like physical hardware and actuation, but also brain-like control and sensing. The most self-evident realization to meet those requirements would be a human-like musculoskeletal robot with a brain-like neural controller. While both musculoskeletal robotic hardware and neural control software have existed for decades, a scalable approach that could be used to build and control an anthropomimetic human-scale robot has not been demonstrated yet. Combining Myorobotics, a framework for musculoskeletal robot development, with SpiNNaker, a neuromorphic computing platform, we present the proof-of-principle of a system that can scale to dozens of neurally-controlled, physically compliant joints. At its core, it implements a closed-loop cerebellar model which provides real-time low-level neural control at minimal power consumption and maximal extensibility: higher-order (e.g., cortical) neural networks and neuromorphic sensors like silicon-retinae or -cochleae can naturally be incorporated.
