A multi-molecular line study of the star-forming globule CB88-230

Context. This paper relates to low-mass star formation in globules, and the interaction of newly-formed stars with their environment. We follow up on the results of our earlier observations of this globule. Aims. Our aim is to study the gas- and dust environment of the young stellar object (YSO) in globule CB88 230, the large-scale molecular outflow triggered by the jet driven by the YSO, and their interaction. Methods. We carried out submillimetre continuum and multi-line molecular observations with several single-dish facilities, mapping the core of the globule and the large-scale outflow associated with the YSO. Results. Dust continuum and molecular line maps (of 12CO, C18O, CS, CH3OH) show a flattened (axes ratio 1.5−1.7), asymmetric core with a full width at half maximum (FWHM)-diameter of 0.16−0.21 pc. Line profiles of 12CO, 13CO(2–1, 3–2), and CS(2–1) show self-absorption near the YSO; the absorption dip is at a slightly (~0.3 km s−1) redder velocity than that of the quiescent gas, possibly indicating infall of cooler envelope gas. The mass of the core, determined from C18O(1–0) observations, is about 8 M⊙, while the virial mass is in the range 5−8M⊙, depending on the assumed density distribution. We detect a slight velocity gradient (~0.98 km s−1 pc−1), though rotational energy is negligible with respect to gravitational and turbulent energy of the core. A fit to the spectral energy distribution of the core gives a dust temperature Td ≈ 18 K and a gas mass of ca. 2 M⊙ (assuming a gas-to-dust ratio of 100). More careful modelling of the sub-mm emission (not dominated by the relatively hot central regions) yields M ≈ 8M⊙. From the molecular line observations we derive gas temperatures of 10−20 K. A Bayesian analysis of the emission of selected molecules observed towards the YSO, yields Tkin ≈ 21.4 K (68% credibility interval 14.5−35.5 K) and volume density n(H2) ≈ 4.6 × 105 cm−3 (8.3 × 104−9.1 × 105 cm−3). We have mapped the well-collimated large-scale outflow in 12CO(3–2). The outflow has a dynamical age of a few 104 yr, and contains little mass (a few 10−2 M⊙). A misalignment between the axis of this large-scale outflow and that of the hot jet close to the YSO indicates that the outflow direction may be changing with time.
A Luzin and Lipschitz condition for the Primitive of Henstock Integral 1

In the paper [3], the concept of SLi was introduced and many class of functions are investigated, such as absolutely continuous functions, functions having negligible variations and functions satisfying the strong Luzin conditions. Here, we prove directly that all Henstock primitives are SLi functions. Moreover, we also investigate all ACG∗ functions and functions that satisfy some Lipschitz condition.

Quantized Scalar Fields Under the Influence of Moving Mirrors and Anisotropic Curved Spacetime

MICHAEL R.R. GOOD: Quantized Scalar Fields Under the Influence of Moving Mirrors and Anisotropic Curved Spacetime. (Under the direction of Charles R. Evans and Paul R. Anderson.) This thesis develops three main topics. First, the moving mirror model is examined where particle and energy creation occur for a minimally coupled, quantized massless scalar field. New exactly solvable trajectories are introduced such that the Bogolubov transformation coefficients are found and energy flux is calculated. The integrated solutions are verified on the past and future hypersurfaces using a splitmode technique. The time-dependent acceleration responsible for thermal radiation is revealed. The second main part involves calculations of spectral time evolution analysis of those trajectory solutions which are asymptotically inertial and unitary by construction. Quanta summing, energy flux integration and energy packet summations are compared and verified. The third main piece involves renormalization counterterms for the field fluctuations and energy density terms in curved spacetime using a quantized scalar field with arbitrary mass and general curvature coupling. Adiabatic regularization is used to generate the counterterms for 〈φ2〉 and the energy density in a general Bianchi Type I anisotropic spacetime. The results are verified in both the isotropic and conformal coupling limits.
A Physics-Based Threshold Voltage Model for Junction-Less Double Gate FETs Having Vertical Structural and Doping Asymmetry

A physics-based threshold voltage model of junction-less (JL) double gate (DG) FETs with vertical structural and doping asymmetry is being proposed in this paper. The numerical implementation of vertical asymmetric doping in the FET devices modeling has been studied extensively. A linear approximation, as suggested in the post-annealed implantation technique, is introduced to account for asymmetric-doped profile falling within the channel thickness. Furthermore, Bhaskar’s approximation of sinusoidal has been implemented in the solution to impart due accuracy in the modeling overextended range of device parameters. Overall, appropriate implementation of these mathematical techniques has reduced the complexity of the full evanescent mode analysis immensely and has together retained the accuracy in the solution. The simplicity of the model has provided flexibility to study structural and doping asymmetry together for JL DG FET. Synopsys Sentaurus Device simulation tool has been used for verification of the model results.
Fluctuation in Sea-Level and Associated Morphological Response: Examples from Denmark

Abstract. Daten von Pegelbeobachtungen in Danemark zeigen zwei verschiedenartige Tendenzen des jahrlichen Mittelwasserstandes im Verlauf der letzten 90 Jahre. Stationen im nordlichen Teil des Landes zeigen eine fallende Tendenz (—0.39 mm pro Jahr in Hirtshals), wahrend Stationen im sudlichen Teil eine steigende Tendenz (+1.08 mm pro Jahr in Fredericia) zeigen. Dieser regionale Unterschied kann zum Teil durch isostatische Landhebung erklart werden. Es gibt auch eine ausgepragte saisonale Anderung im Wasserstand: niedriger Wasserstand im Fruhjahr und hoher Wasserstand im Herbst. Beispiele von kustengeologischen Konsequenzen dieser Wasserstandvariationen werden besprochen. Die Diskussion befast sich auch mit postglazialen Kustenveranderungen in einem Gebiet, in dem die isostatische Hebung auch noch heute andauert.
Screen Space Ambient Occlusion for Virtual and Mixed Reality Factory Planning.

Ambient occlusion represents one aspect of global illumination, simulating the actual accessibility of surfaces for indirect illumination due to occlusion of nearby geometry. Recently the approximation in screen space made it feasible for realtime applications. We focus on the utilization of screen space ambient occlusion (SSAO) in virtual and mixed reality environments, especially considering scenes with a large spatial extent and massive amounts of data, typical for industrial factory planning scenarios. Therefore, a sophisticated screen space approach closer to the original definition of ambient occlusion is presented and compared with existing techniques considering the visual quality. Furthermore, we introduce a method to avoid the disappearance of the SSAO effect in depth for scenes with a large spatial extent. A user study compares the impact of our approach to standard SSAO and standard phong shading, regarding the several cues of human depth perception in a virtual and a mixed reality scenario. The evaluation underlines the benefit of our approach for pure virtual scenes and additionally illustrates a different perception of the cues regarding virtual scenes with a half transparent overlay-image of the real world, typical for mixed reality discrepancy check scenarios.
A Fourier restriction theorem for a perturbed hyperbolic paraboloid: polynomial partitioning

We consider a surface with negative curvature in R3,\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{\mathbb {R}}}^3,$$\end{document} which is a cubic perturbation of the saddle. For this surface, we prove a new restriction theorem, analogous to the theorem for paraboloids proved by L. Guth in 2016. This specific perturbation has turned out to be of fundamental importance also to the understanding of more general classes of one-variate perturbations, and we hope that the present paper will further help to pave the way for the study of general perturbations of the saddle by means of the polynomial partitioning method.
Design High Speed Conventional D Flip-Flop using 32nm CMOS Technology

A Delay (D) flip-flop is an edge triggering device. A high speed, low power consumption, positive edge triggered conventional Delay (D) flip-flop can be designed for increasing the speed of counter in Phase locked loop, using 32nm CMOS technology. The conventional D flip-flop has higher operating frequencies but it features static power dissipation. The designed counter can be used in the divider chip of the phase locked loop. A divide counter is required in the feedback loop to increase the VCO frequency above the input reference frequency. The propose circuit will be faster than conventional circuit as it will be a fast reset operation. The circuit will be consuming less power as it prevents short circuit power consumption. The circuit operates at low voltage power supply.
New teaching methods and their effects on the Data Acquisition and Interface Technology course

Data Acquisition and Interface Technology is a professional foundation course for students majoring in measurement control technology and instrumentation at Southwest Petroleum University in Chengdu, China. As a national distinctive major, it is an important course to deliver and, therefore, this study taking one of the classes in 2011 as an example, focussed on and examined the teaching process from the perspective of theory and practical skills. Specifically, the objective of the study was to research the effect of blackboard writing and multiple teaching method on the students’ studying enthusiasm and initiative, along with their practical ability and creativity. The results obtained suggest that the proposed teaching method is useful and effective, and that the method has helped reach the major’s professional cultivation requirements as set up by the syllabus outlined in the engineering education system.

Experimental analysis of hydrodynamics in a radially agitated tank

A PIV technique is used to analyze the local hydrodynamics generated by a Rushton turbine. Different types of motion coexist in the tank: the mean flow (or global circulation), the periodic fluctuations (or trailing vortices) induced by the blade rotation in the impeller region, and the turbulent fluctuations (that dissipate the kinetic energy). These three kinds of motion can be estimated after experiments as soon as a triple decomposition of the velocity is performed. The mean velocity, the periodically induced stress, and the Reynolds stress are analyzed in the agitated tank, close to the impeller. These data are used for two purposes: to identify and quantify the transfer of kinetic energy between mean flow, periodic flow, and turbulence; and to estimate the dissipation rate of turbulent kinetic energy (TKE) from the balance of TKE, in which each term will be derived from experiments. Characteristics of turbulence are also presented and discussed.
Estimation in the single change-point hazard function for interval-censored data with a cure fraction

ABSTRACT In reliability or survival analysis, the hazard function plays a significant part for it can display the instantaneous failure rate at any time point. In practice, the abrupt change in hazard function at an unknown time point may occur after a maintenance activity or major operation. Under these circumstances, identifying the change point and estimating the size of the change are meaningful. In this paper, we assume that the hazard function is piecewise constant with a single jump at an unknown time. We propose the single change-point model for interval-censored survival data with a cure fraction. Estimation methods for the proposed model are investigated, and large-sample properties of the estimators are established. Simulation studies are carried out to evaluate the performance of the estimating method. The liver cancer data and breast cancer data are analyzed as the applications.
Spherical Fuzzy Logarithmic Aggregation Operators Based on Entropy and Their Application in Decision Support Systems

Keeping in view the importance of new defined and well growing spherical fuzzy sets, in this study, we proposed a novel method to handle the spherical fuzzy multi-criteria group decision-making (MCGDM) problems. Firstly, we presented some novel logarithmic operations of spherical fuzzy sets (SFSs). Then, we proposed series of novel logarithmic operators, namely spherical fuzzy weighted average operators and spherical fuzzy weighted geometric operators. We proposed the spherical fuzzy entropy to find the unknown weights information of the criteria. We study some of its desirable properties such as idempotency, boundary and monotonicity in detail. Finally, the detailed steps for the spherical fuzzy decision-making problems were developed, and a practical case was given to check the created approach and to illustrate its validity and superiority. Besides this, a systematic comparison analysis with other existent methods is conducted to reveal the advantages of our proposed method. Results indicate that the proposed method is suitable and effective for the decision process to evaluate their best alternative.
Theory and simulations of spherical and cylindrical Langmuir probes in non-Maxwellian plasmas

The collected current by spherical and cylindrical Langmuir probes immersed in an unmagnetized and collisionless non-Maxwellian plasma at rest are theoretically studied, and analytical expressions for the currents of attracted and repelled plasma particles are presented. We consider Kappa, Cairns and the generalized Kappa–Cairns distributions as possible models for the velocity field in the plasma. The current–voltage characteristics curves are displayed and discussed. Furthermore, comparisons with the collected currents in Maxwellian plasmas are given. The results of Particle-in-Cell (PIC) simulations of spherical and cylindrical probes in non-Maxwellian plasmas are also presented, and compared with the theoretical expressions. The results for the collected currents by the Langmuir probes obtained by PIC simulations are in good agreement with the corresponding analytical expressions.

Weak shock reflection in channel flows for dense gases

The canonical problem of transonic dense gas flows past two-dimensional compression/expansion ramps has recently been investigated by Kluwick & Cox (J. Fluid Mech., vol. 848, 2018, pp. 756–787). Their results are for unconfined flows and have to be supplemented with solutions of another canonical problem dealing with the reflection of disturbances from an opposing wall to finally provide a realistic picture of flows in confined geometries of practical importance. Shock reflection in dense gases for transonic flows is the problem addressed in this paper. Analytical results are presented in terms of similarity parameters associated with the fundamental derivative of gas dynamics $(\unicode[STIX]{x1D6E4})$ , its derivative with respect to the density at constant entropy $(\unicode[STIX]{x1D6EC})$ and the Mach number $(M)$ of the upstream flow. The richer complexity of flows scenarios possible beyond classical shock reflection is demonstrated. For example: incident shocks close to normal incidence on a reflecting boundary can lead to a compound shock–wave fan reflected flow or a pure wave fan flow as well as classical flow where a compressive reflected shock attached to the reflecting boundary is observed. With incident shock angles sufficiently away from normal incidence regular reflection becomes impossible and so-called irregular reflection occurs involving a detached reflection point where an incident shock, reflected shock and a Mach stem shock which remains connected to the boundary all intersect. This triple point intersection which also includes a wave fan is known as Guderley reflection. This classical result is demonstrated to carry over to the case of dense gases. It is then finally shown that the Mach stem formed may disintegrate into a compound shock–wave fan structure generating an additional secondary upstream shock. The aim of the present study is to provide insight into flows realised, for example, in wind tunnel experiments where evidence for non-classical gas dynamic effects such as rarefaction shocks is looked for. These have been predicted theoretically by the seminal work of Thompson (Phys. Fluids, vol. 14 (9), 1971, pp. 1843–1849) but have withstood experimental detection in shock tubes so far, due to, among others, difficulties to establish purely one-dimensional flows.
Equivalence Among Flat Filters, Dirty Derivative-Based PID Controllers, ADRC, and Integral Reconstructor-Based Sliding Mode Control

We explore the equivalence among flat filters, dirty derivative-based proportional integral derivative (PID) controllers, active disturbance rejection control, and integral reconstructor-based sliding mode control, in the context of SISO second-order, perturbed, pure integration systems. This is the prevailing paradigmatic class of differentially flat systems or feedback linearizable systems. The equivalence is valid beyond the second-order pure integration systems. However, PID controllers of such plants do not make much sense without imposing assumptions that will move the considerations out of the pure integration systems case. The equivalence among the rest of the controllers is valid for any finite order pure integration system.

Recent results of Daya Bay Experiment

The Daya Bay reactor neutrino experiment aimed to precisely measure the least known mixing angle θ13. In March 2012, Daya Bay announced the non-zero value with more than 5σ. With more statistics, less background and better control of systematics, the Daya Bay experiment is continuously improving the precision of sin2 2θ 13 as well as the effective neutrino mass squared differences. In this paper, I will report the recent oscillation results, which are the most precise measurement of the oscillation parameter θ 13 and |Δmee2|. With 1230 days of data, sin2 2θ 13 is measured to be [8.41 ± 0:27(stat.) ± 0.19(syst.)]×10-2 , and |Δmee2| = [2.50±0.06(stat.)±0.06(syst.)]×10-3 eV2 with X 2 /NDF = 232.6/263. An independent measurement with the inverse beta decay neutron captured on hydrogen will also be presented.
