On the origin of non self-gravitating filaments in the ISM

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: {Filaments are ubiquitous in the interstellar medium as recently emphasized by Herschel, yet their physical origin remains elusive} {It is therefore important to understand the physics of molecular clouds to investigate how filaments form and what is the role played by various processes such as turbulence and magnetic field.} {We use ideal MHD simulations to study the formation of clumps in various conditions including different magnetization and Mach numbers as well as two completely different setup. We then perform several analysis to compute the shape of the clumps and their link to velocities and forces using various approaches.} {We find that on average, clumps in MHD simulations are more filamentary that clumps in hydrodynamical simulations. Detailed analyses reveal that the filaments are in general preferentially aligned with the strain which means that these structures simply result from the strech induced by turbulence. Moreover filaments tend to be confined by the Lorentz force which therefore lead them to survive longer in magnetized flows. We show that they have in all simulations a typical thickness equal to a few grid cells suggesting that they are primarily associated to the energy dissipation within the flow. We estimate the order of magnitude of the dissipation length associated to the ion-neutral friction and conclude that in well UV shielded regions it is of the order of 0.1 pc and therefore could possibly set the typical size of non self-gravitating filaments.} {Filaments are ubiquitous because they are the results of the very generic turbulent strain and because magnetic field help to keep them coherent. We suggest that energy dissipation is playing a determinant role in their formation.}

description: A comprehensive physical model of adiabatic three wave mixing is developed for the fully nonlinear regime, i.e. without making the undepleted pump approximation. The conditions for adiabatic evolution are rigorously derived, together with an estimate of the bandwidth of the process. Furthermore, these processes are shown to be robust and efficient. Finally, numerical simulations demonstrate adiabatic frequency conversion in a wide variety of physically attainable configurations.

description: With growing advances in three-dimensional (3D) printing technology, the availability and diversity of printing materials has rapidly increased over the last years. 3D printing has quickly become a useful tool for biomedical and various laboratory applications, offering a tremendous potential for efficiently fabricating complex devices in a short period of time. However, there still remains a lack of information regarding the impact of printing materials and post-processing techniques on cell behavior. This study introduces real-time live-cell imaging technology as a fast, user-friendly, and high-throughput screening strategy to verify the in vitro biocompatibility of 3D printed materials. Polyacrylate-based photopolymer material was printed using high-resolution 3D printing techniques, post-processed using three different procedures, and then analyzed with respect to its effects on cell viability, apoptosis, and necrosis of adipogenic mesenchymal stem cells (MSCs). When using ethanol for the post-processing procedure and disinfection, no significant effects on MSCs could be detected. For the analyses a novel image-based live-cell analysis system was compared against a biochemical-based standard plate reader assay and traditional flow cytometry. This comparison illustrates the superiority of using image-based detection of in vitro biocompatibility with respect to analysis time, usability, and scientific outcome.

Year: 2017

description: Auf den Punkt ...
Die umfassende Lohnkoordinierung und eine relativ ausgeglichene Einkommensverteilung galten lange Zeit als zentrale Merkmale des deutschen Kapitalismusmodells und als Vorbedingung seiner ausgeprägten internationalen Konkurrenzfähigkeit.
Die Lohnentwicklung der letzten beiden Jahrzehnte zerfällt in zwei Phasen, rückläufige Löhne bis zur Finanzmarktkrise und einen tendenziellen Lohnanstieg danach, der aber den Einbruch der Lohnquote nicht vollständig auffangen konnte.
Die Lohnungleichheit hat deutlich zugenommen. Dies liegt sowohl am Rückgang der Tarifbindung als auch an der Schwächung der Lohnkoordination zwischen den Branchen, der Ausweitung des Niedriglohnsektors sowie dem Anstieg der höheren Arbeitnehmerentgelte.
Die Branchenentwicklungen sind, trotz ähnlicher Herausforderungen wie der Auslagerung von Tätigkeiten aus dem Tarifbereich, unterschiedlich. In der Metallindustrie gehen Modernisierungs- und Fragmentierungstendenzen der Lohnfindung Hand in Hand, in den Dienstleistungssektoren des Bankgewerbes und des Einzelhandels ist die Modernisierung der Entgeltstrukturen blockiert.
Der Staat hat mit der Einführung des gesetzlichen Mindestlohns eine wichtige Rolle in der Lohnfindung übernommen, aber er kann die Lohnkoordinierung durch Tarifverträge nicht ersetzen. Die weitere Entwicklung des Modells steht und fällt deshalb mit der Organisationsmacht und der Handlungsfähigkeit der Tarifvertragsparteien.

description: Observations performed with the Fermi-LAT telescope have revealed the presence of a spectral break in the GeV spectrum of flat-spectrum radio quasars (FSRQs) and other low- and intermediate-synchrotron peaked blazars. We propose that this feature can be explained by Compton scattering of broad-line region (BLR) photons by a non-thermal population of electrons described by a log-parabolic function. We consider in particular a scenario in which the energy densities of particles, magnetic field, and soft photons in the emitting region are close to equipartition. We show that this model can satisfactorily account for the overall spectral energy distribution of the FSRQ 3C 454.3, reproducing the GeV spectal cutoff due to Klein-Nishina effects and a curving electron distribution.

description: Physicochemical properties of spinel ZnFe2O4 (ZFO) are known to be strongly affected by the distribution of the cations within the oxygen lattice. In this work, the correlation between the degree of inversion, the electronic transitions, the work function, and the photoelectrochemical activity of ZFO was investigated. By room-temperature photoluminescence measurements, three electronic transitions at approximately 625, 547, and 464 nm (1.98, 2.27, and 2.67 eV, respectively) were observed for the samples with different cation distributions. The transitions at 625 and 547 nm were assigned to near-band-edge electron-hole recombination processes involving O2- 2p and Fe3+ 3d levels. The transition at 464 nm, which has a longer lifetime, was assigned to the relaxation of the excited states produced after electron excitations from O2- 2p to Zn2+ 4s levels. Thus, under illumination with wavelengths shorter than 464 nm, electron-hole pairs are produced in ZFO by two apparently independent mechanisms. Furthermore, the charge carriers generated by the O2- 2p to Zn2+ 4s electronic transition at 464 nm were found to have a higher incident photon-to-current efficiency than the ones generated by the O2- 2p to Fe3+ 3d electronic transition. As the degree of inversion of ZFO increases, the probability of a transition involving the Zn2+ 4s levels increases and the probability of a transition involving the Fe3+ 3d levels decreases. This effect contributes to the increase in the photoelectrochemical efficiency observed for the ZFO photoanodes having a larger cation distribution.

description: For a class of partial differential algebraic equations (PDAEs) of quasi-linear type which include nonlinear terms of convection type a possibility to determine a time and spatial index is considered. As a typical example we investigate an application from plasma physics. Especially we discuss the numerical solution of initial boundary value problems by means of a corresponding finite difference splitting procedure which is a modification of a well known fractional step method coupled with a matrix factorization. The convergence of the numerical solution towards the exact solution of the corresponding initial boundary value problem is investigated. Some results of a numerical solution of the plasma PDAE are given.

description: Previous publications regarding the project “Gentelligent Components for Machine Tools” presented the design of a new sensory z-slide for a 5-axis machining center. Equipped with several strain sensors, the new slide is able to “feel” the machining process by measuring the process forces and vibrations. Here, a challenge is the detection of mechanical strains in the slide without degrading its high global stiffness. The application of micro strain gauges in small notches on the slide represents a promising approach for the improvement of the sensitivity as well as the integration of sensors into the slide. This paper presents the utilization of the sensing axis-slide in a manufacturing environment. For this purpose, a first prototype of the slide is integrated into a milling center DMG HSC 55 linear. In this test machine, the dynamic characteristics of the integrated slide are identified with frequency response function measurements. Based on force measurements with a dynamometer, force calibration matrices are computed to calculate the forces at the tool center point from the measured strain signals during milling processes. The force sensing with the slide allows furthermore the identification of tool characteristics such as the static tool stiffness. This parameter is estimated from the ratio of the measured contact forces and the set colliding distance when moving the tool smoothly into the work piece. The known tool stiffness enables the detection of the static tool deflection from the force signals during a milling process. In order to compare the detected tool deflection with the real tool deflection, reference measurements on the work piece are performed using a perthometer.

description: Micro-optical sensors integrated into polymer foils hold great promise for a wide range of applications. One major challenge to date is the reliable, large-scale and cost-effective manufacturing of the required waveguide structures. Several techniques are currently investigated in the field, hot-embossing being particularly promising. In this work, we discuss hot embossing of polymer optical waveguides. We present our recent results in the area of stamp manufacturing and waveguide fabrication. For the characterization of the waveguides, the refractive index, the transmission losses and the beam profile of the coupled light are measured. We also describe next steps towards more advanced waveguides.

description: The Rayleigh-Taylor instability of a compressible plasma in the presence of a horizontal magnetic field is investigated, taking into account the effects of finite Larmor radius. Only transverse perturbations are considered. The problem is shown to be characterized by a variational principle. Using it, the dispersion relation is obtained for a plasma layer of finite thickness and having an exponentially varying density. It is found that the finite Larmor radius effects can thoroughly stabilize unstable configurations. For configurations which are not completely stabilized, the compressibility stabilizes some of the disturbances which are unstable for an incompressible plasma. © 1993, Walter de Gruyter.

description: One of the so-called viable modified gravities is analyzed. This kind of gravity theories are characterized by a well behavior at local scales, where General Relativity is recovered, while the modified terms become important at the cosmological level, where the late-time accelerating era is reproduced, and even the inflationary phase. In the present work, the future cosmological evolution for one of these models is studied. A transition to the phantom phase is observed. Furthermore, the scalar-tensor equivalence of f(R) gravity is also considered, which provides important information concerning this kind of models.

description: This article presents an experimental analysis on cutting forces in fast tool servo-based face milling of micro structures. These structures can be used as a binary information carrier [1]. For a proper process design on a wide range of materials, knowledge of the cutting forces is necessary. The analysis was conducted on the materials Al7075, AISI4042 and TiAl6V4. The investigated parameters are cutting speed, feed, depth of cut, variable depth of cut change and frequency of change. The experiments were conducted according to a full-factorial design using two levels for all parameters and with the tool in full engagement. The used tool system is based on a piezoelectric actuator, enabling tool tip deflections up to 4.5 kHz with an amplitude of 30 μm. A precise linkage to the angular spindle position allows adjusting the deflection over the width of the rotatory tool tip movement. In analogy to the information carrying micro patterns, sinusoidal structures are generated in the engagement range from 45 to 135 degrees angular tool tip position. In order to minimize possible superimposed vibrations of the dynamometer and amplitude gains of high frequency force signals, a filter is used. The filter is based on an inverse function of the force measurement transfer behavior system with mounted specimen. The effects are evaluated on the mean values of the extracted force signals between 45 and 135 degrees engagement range and compared to the effects of machining without variable depth of cut.

description: We prove that the one-player game Solitaire Clobber 2 is equivalent to an optimization problem on a set of words defined by seven classes of forbidden patterns when played on the line or on the cycle. This enables us to show that this game is solvable in linear time. Using this word representation, we also prove that, playing on the cycle, it is always possible to remove at least 2n/3 pawns, and we give a configuration for which it is not possible to do better, answering questions recently raised by Duchˆene et al.
The Fermi volume as a probe of hidden order

description: We demonstrate that the volume of the Fermi surface, measured very precisely using de Haas-van Alphen oscillations, can be used to probe changes in the nature and occupancy of localized electronic states. In systems with unconventional ordered states, this allows an underlying electronic order parameter to be followed to very low temperatures. We describe this effect in the field-induced antiferroquadrupolar (AFQ) ordered phase of PrOs4Sb12, a heavy fermion intermetallic compound. We find that the phase of de Haas-van Alphen oscillations is sensitively coupled, through the Fermi volume, to the configuration of the Pr f-electron states that are responsible for AFQ order. In particular, the β-sheet of the Fermi surface expands or shrinks as the occupancy of two competing localized Pr crystal field states changes. Our results are in good agreement with previous measurements, above 300 mK, of the AFQ order parameter by other methods. In addition, the low temperature sensitivity of our measurement technique reveals a strong and previously unrecognized influence of hyperfine coupling on the order parameter below 300 mK within the AFQ phase. Such hyperfine couplings could provide insight into the nature of hidden order states in other systems.

description: Установлено, что содержание влаги в метровом слое почвы перед посевом больше при возделывании по озимой пшенице, что обусловлено ранним сроком уборки и светлым цветом растительных остатков, которые отражали солнечные лучи и предотвращали не производительные потери влаги. На момент полного созревания содержание влаги также больше при повторном посеве, что в данном случаи обусловлено более коротким вегета-ционным периодом, чем при возделывании по другим предшественникам. На формирова-ние одной тонны зерна озимой пшеницы меньше всего расходуется влаги при возделыва-нии по бобовым предшественникам – 877 м3 по гороху и 892 м3 по сое. В то время как при повторном посеве достоверно больше – 1392 м3, что по отношению к лучшему пока-зателю (по гороху) израсходуется в 1,6 раза больше влаги.
description: It is established that moisture content in a meter layer of earth before crops is more at cultivation on a winter wheat that is caused by the early term of cleaning and light color of the vegetable remains which reflected sunshine and prevented not productive losses of moisture. At the time of full maturation, the moisture content is also greater when re-sowing, which in this case is due to a shorter growing season than when cultivated according to other predecessors. The formation of one ton of grain of winter wheat consumes the least amount of moisture in the cultivation of leguminous precursors – 877 m3 of peas and 892 m3 of soybeans. While at repeated crops it is reliable more – 1392 m3, which relative to the best indicator (for peas) consumed 1,6 times more moisture.

description: In vibration control with piezoceramics, a high coupling of the piezoelement with the structure is desired. A high coupling improves the damping performance of passive techniques like shunt damping. The coupling can be influenced by a the material properties of the piezoceramics, but also by the placement within the structure and the size of the transducer. Detailed knowlegde about the vibration behavior of the structure is required for this. This paper presents an in-depth analysis of the optimal shape of piezoelectric elements. General results for one-dimensional, but inhomogeneos strain distribution are provided. These results are applied to the case of a longitudinal transducer and a bending bimorph. It is obtained that for maximum coupling, only a certain fracture of the volume should be made of piezoelectric material.

description: The inspection of capital goods with complex geometries is a challenging task due to the limited maneuvering and measuring space available. We developed a set of optical measurement systems for the inline inspection of such machines and capital goods. At first we introduce a borescopic fringe projection system based on of-the-shelf components. It is capable of detecting geometric variances in hard to reach areas, e.g. inside machines or in between parts with highly complex geometries like blade integrated discs (blisks). Single parts like compressor blades are measured with an inverse fringe projection system, which uses fully adaptable fringe patterns. The adaptable patterns lead to a high sensitivity and high speed. Results can be achieved with only one fringe pattern per measurement. In order to perform microscopic measurements and surface characterizations, we use a michelson interferometer with advanced 3D reconstruction algorithms to detect microscopic variances of the objects surface. These newly developed algorithms lead to higher sensitivity and improved results. Together these three inspection systems enable us to detect and to quantify geometric defects or variances of different industrial parts. Based on this information the prediction of the reliability of a part can be improved and the lifetime of an industrial part can be extended leading to a reduction of maintenance costs.

description: In our previous paper, we reported on switchable monolayer MoS2 transistors with a high on-off ratio and we claim that dielectric screening can be used to increase the mobility of monolayer MoS2. We estimated its mobility using a method previously applied by Lemme et al. to top-gated graphene nanoribbons. We discuss here the comments raised by M. Fuhrer and J. Hone in their post 1301.4288 and give our own estimates of the possible errors in previous mobility measurements and their origins.

description: We apply Runge-Kutta methods to linear partial differential-algebraic equations of the form $Au_t(t,x) + B(u_{xx}(t,x)+ru_x(t,x))+Cu(t,x) = f(t,x)$, where $A,B,C\in\R^{n,n}$ and the matrix $A$ is singular. We prove that under certain conditions the temporal convergence order of the fully discrete scheme depends on the time index of the partial differential-algebraic equation. In particular, fractional orders of convergence in time are encountered. Furthermore we show that the fully discrete scheme suffers an order reduction caused by the boundary conditions. Numerical examples confirm the theoretical results.

description: The regeneration process of jet engines is a highly complex, expensive and time-consuming. Especially the regeneration of high pressure turbine blades and compressor blisks are at the border of what is technically feasible. These components are highly loaded and thus substantial wear occurs. The blades and blisks must be overhauled or replaced regularly. The existing repair methods for these parts are inflexible and cannot be applied in many cases, resulting in a large number of scrapped parts. Therefore a new turbine blade regeneration process is presented. The goal of the improved process is to reduce the scrap rate and cost. This process includes an early evaluation of the condition of the hot-gas path components before disassembly, new detection methods for defects on the turbine blades surfaces, and more flexible manufacturing processes. The process is supported by production process simulations and functional simulations to predict the optimal regeneration path depending on the blade condition and the business model of the customer. The paper also presents a new approach for compressor blisk regeneration. This process will be developed and validated in the next years. New challenges in structural mechanics, aerodynamics, and manufacturing must be addressed due to the complexity of blisks. As part of the ongoing research, three new blisks will be designed and subjected to the complete regeneration path, which is also supported by simulations. In order to validate the simulations, their results will be compared to experimental results of the regenerated components on a compressor test rig.

description: Planar optronic sensor systems are networks of integrated light sources, detectors and sensors, connected by optical waveguides on thin polymer films. This way, sensor networks can be realized completely optically for measuring quantities such as temperature, strain or chemical concentration. Applications unfold in structural health monitoring and chemical analysis. Waveguides represent a key element in this concept for signal transmission and the integration of interacting system components. The cost-effective and high-throughput production of polymer waveguides can be achieved by utilization of flexographic and inkjet printing. This particular application of the flexographic printing process is investigated for the first time and results show the suitability of the unique approach for production of waveguides with a minimum lateral dimension of 50 microns and parabolic cross sections. Inkjet printing is used as a complementary technique to deposit small amounts of materials at specific locations on substrates prestructured by flexographic printing. Additionally, inkjet printing allows for a thinner diameter of polymer waveguides if required, and new designs can be created easily as this process does not require invariable masks or printing forms. We show the structure of printed waveguides in layer systems consisting of core and claddings and discuss the challenges of additive manufacturing in a printing process. The resulting geometrical properties of the novel production process are described as the basis for a subsequent integration of sensors, sources, and sinks.

description: В Ставропольском крае традиционно большое внимание уделяется производству высоко-качественного зерна озимой пшеницы, поэтому контроль его формирования является ак-туальной задачей для сельскохозяйственной отрасли. Сегодня ее целесообразно решать на основе данных ДЗЗ. Теоретической основой этому является существование связи меж-ду NDVI и содержанием хлорофилла в растениях озимой пшеницы, динамика которого в онтогенезе, в свою очередь, параллельна  изменениям азота. Исследования позволили проследить ход формирования качества зерна озимой пшеницы для всей территории Ставропольского края в 2018 сельскохозяйственном году. Проведен сравнительный ана-лиз прогнозных показателей и результатов обследования качества зерна озимой пшеницы.
description: In the Stavropol Territory, traditionally, much attention is paid to the production of high-quality winter wheat grain, therefore, the control of its formation is an urgent task for the agricultural industry. Today it is advisable to solve it on the basis of remote sensing data. The theoretical ba-sis for this is the existence of a link between NDVI and the content of chlorophyll in winter wheat plants, the dynamics of which in ontogenesis, in turn, parallel to changes in nitrogen. Studies have allowed to follow the course of formation of the quality of grain of winter wheat for the entire territory of the Stavropol Territory in the 2018 agricultural year. A comparative analysis of forecast indicators and the results of a survey of the quality of winter wheat grain has been carried out.

description: In order to optimize the cutting performance of end mills, the geometry of such cutters is optimized by toolmakers constantly. As a result of geometric changes, process forces can be reduced, i.e. by serrated end mills. Tools with unequal helix angles can lead to an increase of process stability. In this paper, a method to calculate the process forces of end mills with complex geometries is presented. The method for calculating the process forces is designed for the application for stability analysis of end mill cutters with complex geometries. A basic introduction of the method for the stability prediction of such tools is given. Cutting forces of end mills are analyzed at incremental axial depth of cuts to show the influence of the tool geometry on the process forces. The comparison with experimental data verifies this method and shows the influence of further effects on the process forces. Furthermore, stability charts obtained with the Semi-Discretization Method are presented to show the potential of end mills with complex geometries regarding stability improvement.
