description: In this paper, two dimensional state retrial queueing system with two non identical parallel servers is considered. Incoming calls (primary calls) arrive at the server according to a Poisson process. Repeating calls also follows the same fashion. Service times of two servers follow exponential distribution with different rates. An incoming call that finds the servers busy, joins an orbit and retries after some random amount of time. Time dependent probabilities of exact number of arrivals and exact number of departures at when the servers are free or when one server is busy or when both servers are busy are derived for the system. Finally busy period distribution obtained to illustrate the system dynamics.

description: A new distribution for modeling the two approaches (physical and actuarial) of reliability problems is introduced. The statistical properties including the moments, mode, quantile function are derived. Some reliability measures including the mean residual life and hazard rate are derived. An alternative measure for total time of test (TTT) for evaluation of the interfailure times is drived.The unknown parameters of the new distribution are estimated using the maximum likelihood approach. Furthermore, the asymptotic consistency of the estimated parameters is evaluated through a simulation study. Two real-life datasets were used to illustrate the applicability of the new distribution and comparison with already existing distributions.

description: This file is a supplementary illustration for a manuscript submitted to PeerJ about a new insect species (Hymenoptera: Ceraphronoidea: Conostigmus) found in Baltic amber.
Ceraphronoids are some of the most commonly collected hymenopterans, yet they remain rare in the fossil record. Conostigmus sp. nov. from Baltic amber represents an intermediate form between the type genus, Megaspilus, and one of the most species-rich megaspilid genera, Conostigmus, supporting the hypothesis that Megaspilus is nested within Conostigmus. We describe the new species using 3D data collected with synchrotron-based micro-CT equipment. This non-invasive technique allows for quick data collection in unusually high resolution, revealing morphological traits that are otherwise obscured by the amber. In describing this new species, we revise the diagnostic characters for Ceraphronoidea and discuss possible reasons why minute wasps with a pterostigma are often misidentified as ceraphronoids. Based on the lack of ceraphronoid characteristics, we remove Dendrocerus dubitatus Brues 1937, Stigmaphronidae, and Radiophronidae from Ceraphronoidea and consider them as incertae sedis. We also provide some guidance for their future classification.

The two specimens for the study were obtained from the private collection of Baltic amber inclusions of Christel and Hans Werner Hoffeins (Hamburg, Germany). Specimens are embedded in Polyester resin (Voss-Chemie, Uetersen) and are deposited in the Deutsches Entomologisches Institut (Müncheberg, Germany).
Is WISEP J060738.65+242953.4 Really A Magnetically Active, Pole-on L Dwarf?

description: The interplay of rotation and manifested magnetic activity on ultracool dwarfs (UCDs) is of key importance for gathering clues as to the operation of the dynamos within these objects. A number of magnetized UCDs host kG-strength magnetic fields. It was recently reported that the L8 dwarf WISEP J060738.65+242953.4 is a radio-emitting UCD that is likely observed pole-on, due to its lack of photometric variability and narrow spectral lines. Follow-up radio observations at Arecibo Observatory, together with careful analysis of previously published details, however, suggest that the scientific and statistical significance of the radio and spectroscopic data have been overstated. If the UCD is observed along its aligned spin/magnetic axis, the absence of observed H$α$ activity may present challenges to the auroral model of UCD magnetism, although short or long-term cyclic magnetic activity may explain this behavior. Monte Carlo simulations presented here suggest that the source probably rotates with v sin i=6-12 km s$^{-1}$, indicating that its inclination angle and rotational velocity are unexceptional and that its angular momentum has evolved as expected for brown dwarfs observed in ~1 Myr-old clusters. The discovery and verification of the most rapidly and slowest rotating brown dwarfs place valuable constraints on the angular momentum evolution and magnetic activity history of these objects.

description: We propose new mechanisms for small neutrino masses based on clockwork mechanism. The Standard Model neutrinos and lepton number violating operators communicate through the zero mode of clockwork gears, one of the two couplings of the zero mode is exponentially suppressed by clockwork mechanism. Including all known examples for the clockwork realization of the neutrino masses, different types of models are realized depending on the profile and chirality of the zero mode fermion. Each type of realization would have phenomenologically distinctive features with the accompanying heavy neutrinos.

description: We numerically compute the flow of an electrically conducting fluid in a Taylor-Couette geometry where the rotation rates of the inner and outer cylinders satisfy $Ω_o/Ω_i=(r_o/r_i)^{-3/2}$. In this quasi-Keplerian regime a non-magnetic system would be Rayleigh-stable for all Reynolds numbers $Re$, and the resulting purely azimuthal flow incapable of kinematic dynamo action for all magnetic Reynolds numbers $Rm$. For $Re=10^4$ and $Rm=10^5$ we demonstrate the existence of a finite-amplitude dynamo, whereby a suitable initial condition yields mutually sustaining turbulence and magnetic fields, even though neither could exist without the other. This dynamo solution results in significantly increased outward angular momentum transport, with the bulk of the transport being by Maxwell rather than Reynolds stresses.

description: In the Optical Character Recognition (OCR) system, achieving high recognition performance is important. OCR and visual perception are affected by the inclined characters in each language. Deep learning methods play an important role in the OCR field, which can outperform humans with higher recognition performance. So, in this research, a hybrid deep learning technique is applied to recognize the Gujarati language characters. Initially, Gujarati characters collected from different sources are pre-processed using different techniques. Adaptive Weiner Filter (AWF) is used for noise removal, Binarization, and contrast enhancement is done by Contrast Limited Adaptive Histogram Equalization (CLAHE) method. Finally, a hybrid deep ResNet with Inception model (GoogleNet) is suggested to perform character recognition in the Gujarati language. This hybrid architecture also performs feature extraction tasks, considered a major task in OCR. Python tool is utilized to illustrate the proposed methodology and solve the mathematical model. Scanned documents containing Gujarati characters are engaged to evaluate the robustness of the proposed methodology. Using various performance parameters, the influence of the proposed methodology is examined and its results compared with various deep learning algorithms.

11.2 The GND initiative 2017-2021: Developing a Backbone for the Web of Cultural and Scientific Data
Creators: name: Kett, Jürgen; Hartmann, Sarah
Publisher: name: Zenodo

description: Combing data beyond the boundaries of systems and domains is the major concern of the linked data movement. One serious problem for the semantic web is dealing with reliability: Can the data be trusted and do processes exist that guarantee a high data quality? Of the same importance is sustainability: Is a resource stable enough to be citable, or will it be gone at some point? These questions are of special importance in the context of research, where citability is essential, and for higher-level services that are based on this kind of data. While it is not necessary for every dataset to provide a maximum degree of reliability in order to be useful, we believe that in the heart of the linked data web a reliable and stable core is needed, a backbone of trust, and that cultural heritage institutions are in a unique position to provide parts of this core: connecting their local knowledge bases could lead to a huge graph of cultural and scientific information that is both reliable and persistent. Especially authority files like the “Gemeinsame Normdatei” (GND) make up the perfect bridges and stable anchors for cross-domain connections. Various museums, archives, research organizations and other partners outside the library domain (like Wikipedia) already contribute to the GND and it is widely connected to diverse datasets and collections all over the world. But there is still much to be done to implement our vision of a cross-domain cloud-based interlinking platform. The organization, rules, services and infrastructure around the GND need a complete revision to deal with the quickly growing network and to reconcile the requirements of the heterogeneous domains and disciplines. Further challenges are the strengthening of the support for the management and visualization of semantic connections, the integration into global data generation processes, as well as the utilization of improvements in the area of data analysis and machine learning (datamining). Together with the GND partners, the German National Library will start an initiative to move the GND to the next level. By 2021, the GND is to be gradually modernized, reorganized and expanded. In this lecture, we will line out the key opportunities and challenges and the highlights of our approach.
Modification of magnetohydrodynamic waves by the relativistic Hall effect

description: This study shows that a relativistic Hall effect significantly changes the properties of wave propagation by deriving a linear dispersion relation for relativistic Hall magnetohydrodynamics (HMHD). Whereas, in non- relativistic HMHD, the phase and group velocities of fast magnetosonic wave become anisotropic with an increasing Hall effect, the relativistic Hall effect brings upper bounds to the anisotropies. The Alfveén wave group velocity with strong Hall effect also becomes less anisotropic than non-relativistic case. Moreover, the group velocity surfaces of Alfvén and fast waves coalesce into a single surface in the direction other than near perpendicular to the ambient magnetic field. It is also remarkable that a characteristic scale length of the relativistic HMHD depends on ion temperature, magnetic field strength, and density while the non-relativistic HMHD scale length, i.e., ion skin depth, depends only on density. The modified characteristic scale length increases as the ion temperature increases and decreases as the magnetic field strength increases.

description: All nonlinear dispersive wave equations in the general class $m_t+f(u,u_x)m+(g(u,u_x)m)_x =0$ are known to possess multi-peakon weak solutions. A classification is presented for families of multi-peakon equations in this class that possess conserved momentum; conserved $H^1$ norm of $u$; conserved $H^2$ norm of $u$; conserved $L^2$ norm of $m$; related conservation laws. The results yield, among others, two interesting wide families of equations: $m_t + 2u_x h(u,u_x)m + u (h(u,u_x)m)_x=0$ for which the $H^1$ norm of $u$ is conserved; $m_t -\tfrac{1}{2}u_x h'(u)m + (h(u)m)_x =0$ for which the $L^2$ norm of $m$ is conserved. The overlap of these two families yields a singular equation which is nevertheless found to possess both smooth solitary wave solutions and peakon travelling wave solutions.

description: This article deals with inferences on stress strength reliability in a multicomponent system for Type I generalized half-logistic distribution. It is assumed that the strength and stress components are independently distributed. In this work, we develop some statistical properties of the type I generalized half-logistic distribution. Furthermore, the expression for stress strength reliability for a multicomponent setup was obtained and studied. Two methods to estimate the multicomponent stress-strength reliability maximum likelihood and Bayesian estimation were employed. The Bayes estimates of the multicomponent stress strength reliability are obtained under squared error loss function and using gamma priors for the parameters. Simulation studies were conducted to assess the efficiency of the methods. The importance of this model was studied by applying it to a real life data set.

description: Surface properties are examined in a chiral d-wave superconductor with hexagonal symmetry, whose one-body Hamiltonian possesses the intrinsic spin-orbit coupling identical to the one characterizing the topological nature of the Kane-Mele honeycomb insulator. In the normal state spin-orbit coupling gives rise to spontaneous surface spin currents, whereas in the superconducting state there exist besides the spin currents also charge surface currents, due to the chiral pairing symmetry. Interestingly, the combination of these two currents results in a surface spin polarization, whose spatial dependence is markedly different on the zigzag and armchair surfaces. We discuss various potential candidate materials, such as SrPtAs, which may exhibit these surface properties.

description: This paper analyzes a steady-state finite buffer M/M/1 feedback queue with reverse balking, reverse reneging and multiple working vacations. The concept of reverse balking and reverse reneging evolves from investment businesses wherein more the number of customers associated with a firm less the probability of balking of a customer and similar is the case of reverse reneging. Furthermore, if a customer is dissatisfied with the service provided, he or she may chose to rejoin the queue as a feedback customer. The server exits for working vacations whenever the system becomes empty instead of staying idle in the system. Vacation times and service times during working vacations are all independent random variables following exponential distribution. The model’s steady-state system length distributions are calculated using the matrix approach. Some performance characteristics and cost optimization using ant colony optimization (ACO) are presented. Sensitivity analysis is performed using numerical results which are shown in the form of tables and graphs.

description: Sustainable energy plays a significant role in socio-economic advancement by raising the standard of living of all human beings. Briquetting is the process of compaction of biomass residues into solid fuels in order to increase the effectiveness of thermal capacity, combustion rate, calorific value to name a few. In this paper, we consider not only the occurrence of minor/ major faults but also the other neglected faults such as abnormal sound, overheating of the motor unit, vibration, etc. Such neglected faults may not affect the working of the system at a time but their ignorance may convert into major faults in the future. An ordinary repairman can easily rectify all machine faults except some major faults for which an expert repairman is required. Moreover, we analyse the availability of the system and optimize system profit by using the Artificial Bee Colony optimization algorithm. Furthermore, a graphical study of these parameters is presented.

description: This paper uses the concept of inherent simplicity stemming from the Theory of Constraints to explain whether safety at work is a complex or an exceedingly simple matter. In this context, the study seeks to explore the causalities that govern safety at work, identifying its constructs and presenting logic propositions based on the theory-building blocks: classification, correlation, and causal consistency. To support the research, a dataset composed of 46 work-related accident investigation reports from an elevator industry in Latin America was carefully analyzed using association rules. Moreover, direct observations grounded on inductive reasoning were used to speculate plausive causes concerning the effect of work-related accidents. The research strategy followed common strategies of theory building to reach common sense: theory-to-practice and practice-to-theory. As a result, a conceptual proposition is postulated based on the reasoning that safety at work is governed by very few constructs, and that its complexity is explained through the two elements from inherent simplicity: degrees of freedom (interdependencies between constructs) and harmony (conflicts resolution within the work environment). From the practitioners’ perspective, the study also offers directions towards safety improvements at the organizational level by considering the impact of the interdependencies between constructs in safety at work.

description: Reliability sampling is the methodology often used in manufacturing industries for making decision about the disposition of lots of finished products based on the information generated from a life test. Such a methodology can be applied effectively for isolated lots as well as for a continuous stream of lots through the life tests to ensure control over the quality characteristics that are mainly related to the functioning of the manufacturing items in time. Sampling inspection plans for isolated lots are classified under lot by lot inspection procedures. Cumulative results plans are classified under the sampling inspection for continuous production, which results in continuous stream of lots. This paper presents the notion of life tests for cumulative results plans with a particular reference to chain sampling inspection plans when the lots are formulated from a continuous stream of production. The operating characteristic (OC) function of chain sampling plans for life tests is presented as a measure of performance when the lifetime random variable follows an exponential distribution. A procedure for designing the proposed plans indexed by two points on the characteristic curve for providing protection to the producer and consumer is discussed with illustrations. Tables yielding the parameters of the optimum plans are also provided.

description: Online reviews are now a global form of communication between consumers and E-commerce companies. When it comes to making day-to-day decisions, customers rely heavily on the availability of internet reviews, as well as their trustworthiness and performance. Due to the unique qualities of user reviews, customers are finding it increasingly difficult to define and examining the authenticity and reliability of sentiment evaluations. These sentiment classifications for user reviews can aid in understanding user feelings, review dependability, and customer perceptions of movie items. Deep Learning is a strong technique for learning several layers of data representations or features. When compared to traditional machine learning approaches, deep learning techniques yield better results. To assess, analyze, and weight the usefulness of each review comment, we employed the XLNet Deep Learning Model Approach on balanced movie review dataset.Experimental result demonstrates that the proposed deep learning model achieves higher performance evaluation than those of other classifiers.

description: A density functional theory study of atomic defects and dopants in ternary Z-phase transition-metal nitrides CrMN with M=V, Nb, or Ta is presented. Various defect formation energies of native point defects and of substitutional atoms of other metal elements which are abundant in the steel as well, are evaluated. The dependence thereof on the thermodynamic environment, i.e. the chemical conditions of a growing Z-phase precipitate, is studied and different growth scenarios are compared. The results obtained may help to relate results of experimental atomic-scale analysis, by atom probe tomography or transmission electron microscopy, to the theoretical modeling of the formation process of the Z phase from binary transition metal nitrides.

description: [transcription] Monsieur

La lettre que j'ai l'honneur de vous écrire n'est point destinée à vous souhaiter la bonne année, vous ne pouvez pas douter que je ne vous souhaite toujours toute sorte de prospérité et certainement le renouvellement de l'année n'ajoute rien à la sincérité de mes voeux. Je vous écris principalement au sujet d'une caisse de fossiles qui me vient du Gévaudan. J'avais pris la liberté de vous la faire adresser à Nîmes, et l'on m'a marqué depuis quelque temps qu'elle a dû vous être parvenue par une commodité, je vous prie de vouloir bien à votre plus grand loisir me la faire passer par quelque ami, surtout si cet envoi vous avait occasionné les moindres frais je me flatte que vous voudrez bien me le marquer. On m'a fait espérer qu'il y avait surtout dans cette caisse des bélemnites d'une espèce singulière, je voudrais que cela fut afin de pouvoir vous en présenter.

Je n'aipoint oublié la commission dont vous m'avez chargé[fol. 92v] auprès de M. Bertrand au sujet de quelques recueils d'inscriptions de la Suisse, il a toujours omis de me répondre sur ces objets. Il est vraique la plupart de mes lettres ne luisont parvenues qu'en Italie oùil est actuellement avec Messieurs les comtes Mniszech. Je reçus de luiune lettre au mois d'octobre qui était de Florence. Il ne sera absolument de retour à Berne ou à Yverdon qu'au mois de juin prochain, je le presserai alors plus vivement sur l'objet que vous lui avez demandé.

Votre grand ouvrage doit s'avancer sans doute, je vous prie cependant de ménager vos yeux et votre santé. Malgré le nombre et la beauté de Gruter je trouve qu'il en manque une essentielle, c'est celle des villes ou l'on a trouvé des inscriptions. Je voudrais savoir par exemple si l'on a quelque inscription trouvée à Avignon, je n'ai rien qui me l'indique et je suis forcé ou de me déterminer à des recherches d'une longueur effrayante, ou de rester absolument dans l'ignorance à cet égard.

Continuez-moivotre amitié, Monsieur, et soyez toujours assuré de l'attachement respectueux avec lequel j'ail'honneur d'être

Monsieur

Votre très humble et très obéissant serviteur

Calvet

Avignon ce 25décembre 1767

description: The similarity of the absolute luminosity profiles of Type Ia supernovae (SNIe), as one kind of distance indicator, has led their use in extragalactic astronomy as secondary standard candles. In general, the empirical relationship of SNIa on the absolute peak magnitude $M_{\rm B}$ is calibrated by Cepheid variables in the near distance scale and directly extrapolated to much farther distances. Two main problems arise. First, their calibration, in particular the determination of $M_{\rm B}$, depends on the empirical relationship of Cepheid variables, which suffers from various uncertainties. The second is related to the homogeneity of SNIa in their true $M_{\rm B}$, which is known to be poor in different environments. The observed GW signal of the coalescence of compact binary systems and their electromagnetic counterparts provide the novel and model-independent way to address these two problems. In the era of second-generation GW detectors, the low-redshift GW sources provide a novel method to calibrate the empirical relationship of SNIa, using their self-calibrated distances. Here, we use the event GW170817 to calibrate the empirical relationship in different low redshift ranges, and find that the calibration results are consistent with the ones derived from the Cepheid variables. Moreover, the uncertainties of $M_{\rm B}$ in both methods are also comparable. By the observations of third-generation GW detectors, GW sources can also be used to measure the values of $M_{\rm B}$ for the high-redshift SNIe, which provides a unique opportunity to study the dependence of $M_{\rm B}$ on the local environment, strength of gravity, and the intrinsic properties of the explosion, in addition to test the homogeneity of standard candles. We find that the uncertainties of $M_{\rm B}$ in both high and low redshifts are more than one order of magnitude smaller than the current accuracy.

Residual Sharma-Mittal entropy

description: In this paper, we derive Sharma-Mittal entropy of generalized (k) record values and analyse some of its important properties. We establish some bounds for the Sharma-Mittal entropy of generalized (k) record values. We generate a characterization result based on the properties of Sharma-Mittal entropy of generalized (k) record values for the exponential distribution. We further establish some distribution-free properties of Sharma-Mittal divergence information between the distribution of a generalized (k) record value and the parent distribution. We extend the concept of Sharma-Mittal entropy to the concomitants of generalized (k) record values arising from a Farlie-Gumbel-Morgenstern (FGM) bivariate distribution. Also, we consider residual Sharma-Mittal Entropy and used it to describe some properties of generalized (k) record values.

Skip-lot sampling plan of type SkSP-T

description: This paper clearly assigns skip-lot sampling plan of type SkSP-T with Group Acceptance sampling plan is designing and Burr type XII distribution is applied to determine the lifetime of the product. The new proposed plan parameters are determined by using the two-point method on the Operating Characteristics curve together with consistent producer and consumer risks are specified. Tables are simulated for various parametric values of SkSP-T, Group acceptance sampling plan and Burr type XII distribution. Skip-lot sampling plan of type SkSP-T is also compared with Group acceptance single sampling plan and skip-lot sampling plan of type SkSP-2 with group acceptance sampling plan using Burr type XII distribution. Further, the efficiency of the proposed plan is discussed. Numerical illustration and examples are given to justify the efficiency of the proposed plan.

description: The inverted distribution is the distribution of the reciprocal of a random variable that follows a specified distribution. Here, a new one parameter inverse A(α) distribution has been introduced, which is the reciprocal of the A(α) distribution. An account of mathematical and statistical properties of the new distribution such as survival characteristics, quantile functions, mode, order statistics, ageing intensity function and stochastic ordering have been derived and discussed. Furthermore, from the frequentist view point we discussed several estimation approaches including maximum likelihood method, method of maximum product of spacings, ordinary and weighted least square methods, Cram´er-Von-Mises estimation and Anderson-Darling estimation methods. These methods are compared for both small and large samples by performing an extensive numerical simulation. The flexibility of the new lifetime distribution is demonstrated by modeling a tongue cancer data. The result indicates the superiority for proposed model compared to some popular competing ones.
Approximation of Functions over Manifolds: A Moving Least-Squares Approach

description: We present an algorithm for approximating a function defined over a $d$-dimensional manifold utilizing only noisy function values at locations sampled from the manifold with noise. To produce the approximation we do not require any knowledge regarding the manifold other than its dimension $d$. We use the Manifold Moving Least-Squares approach of (Sober and Levin 2016) to reconstruct the atlas of charts and the approximation is built on-top of those charts. The resulting approximant is shown to be a function defined over a neighborhood of a manifold, approximating the originally sampled manifold. In other words, given a new point, located near the manifold, the approximation can be evaluated directly on that point. We prove that our construction yields a smooth function, and in case of noiseless samples the approximation order is $\mathcal{O}(h^{m+1})$, where $h$ is a local density of sample parameter (i.e., the fill distance) and $m$ is the degree of a local polynomial approximation, used in our algorithm. In addition, the proposed algorithm has linear time complexity with respect to the ambient-space's dimension. Thus, we are able to avoid the computational complexity, commonly encountered in high dimensional approximations, without having to perform non-linear dimension reduction, which inevitably introduces distortions to the geometry of the data. Additionaly, we show numerical experiments that the proposed approach compares favorably to statistical approaches for regression over manifolds and show its potential.

description: In this paper, we have proposed a transformed distribution called inverse Muth (IM) distribution. The expressions for probability density function (pdf), cumulative distribution function (cdf), reliability and hazard function of this distribution are well defined. The statistical properties such as, quantile function, moments, skewness and kurtosis are derived. The methods of estimation such as maximum likelihood estimation (MLE) and maximum product spacing estimation (MPSE) are used to estimate the parameters. The IM distribution is positively skewed and its behavior of hazard rate is upside-down bathtub (UBT) shape. The important finding of the study is that the moments of IM distribution do not exist. A real dataset (the active repair time for airborne communication transceiver) used for application purpose, after taking a natural extension of IM distribution. It is expected that the proposed model would be used as a life time model in field of reliability and its applicability.

Semiclassical theory for liquid-like behaviour of the frustrated magnet $\mathrm{Ca}_{10}\mathrm{Cr}_{7}\mathrm{O}_{28}$

description: We identify the low energy effective Hamiltonian that is expected to describe the low temperature properties of the frustrated magnet $\mathrm{Ca}_{10}\mathrm{Cr}_{7}\mathrm{O}_{28}$. Motivated by the fact that this effective Hamiltonian has $S=3/2$ effective moments as its degrees of freedom, we use semiclassical spinwave theory to study the $T=0$ physics of this effective model and argue that singular spinwave fluctuations destabilize the spiral order favoured by the exchange couplings of this effective Hamiltonian. We also use a combination of classical Monte-Carlo simulations and molecular dynamics, as well as analytical approximations, to study the physics at low, nonzero temperatures. The results of these nonzero temperature calculations capture the liquid-like structure factors observed in the temperature range accessed by recent experiments. Additionally, at still lower temperatures, they predict that a transition to nematic order in the bond energies reflects itself in the spin channel in the form of a crossover to a regime with large but finite correlation length for spiral spin correlations and a corresponding slowing down of spin dynamics.
