description: Recently, great tragedies have occurred, which are caused by the coincidence of various factors in time and in locations. Failure to take into account the fact that different events will coincide in time and location is an error in the forecasting method, since such situations require the use of parallel data, which we will discuss here. The article gives a specific example of the coincidence of 5 natural geological and hydrometeorological events and shows how a natural disaster could have been avoided using a new forecasting method.

description: The use of machine learning promises great potential along the entire value chain of manufacturing companies. Many companies have already recognized the resulting opportunities for increasing enterprise value and are developing their machine learning applications for the production environment. However, despite these efforts, many of the solutions developed fail in the market. Especially small- and medium-sized enterprises have difficulties developing suitable business models for their technical applications. These difficulties arise because companies do not evaluate their business projects sufficiently during the development phases. As a result, unpromising projects are not recognized until late in the development process and thus cause high sunk costs. This paper presents an approach for integrating assessment methods into developing machine learning- driven business models for production. Due to the diametric evolution of information availability and uncertainty during the business model development process, various methods and tools can be used for the assessment depending on the current phase. For this purpose, existing assessment methods are evaluated and contrasted regarding their suitability concerning machine learning-based business models for production. Afterwards, three approaches for the different planning phases of business model development (strategic, tactical, operational) are presented in this paper.

Sending classical information through relativistic quantum channels

description: We investigate how special relativity influences the transmission of classical information through quantum channels by evaluating the Holevo bound when the sender and the receiver are in (relativistic) relative motion. By using the spin degrees of freedom of spin-1/2 fermions to encode the classical information we show that, for some configurations, the accessible information in the receiver can be increased when the spin detector moves fast enough. This is possible by allowing the momentum wave packet of one of the particles to be wide enough while the momentum wave packets of other particles are kept relatively narrow. In this way, one can take advantage of the fact that boosts entangle the spin and momentum degrees of freedom of spin-1/2 fermions to increase the accessible information in the former. We close the paper with a discussion of how this relativistic quantum channel cannot in general be described by completely positive quantum maps.

description: The article considers lithofacies and structural-tectonic conditions of oil and gas formation in the Kura depression. In addition, the formation of oil and gas accumulation zones in the crushing nodes in the Mesozoic deposits was determined and the role of faults in their formation was studied, tectonic crushing zones were found using seismically active zones in these deposits, the issues of prospects analysis were studied and the issues of prospecting and exploration were considered. Taking into consideration that the tectonic crushing zones are formed in Mesozoic deposits composed mainly of competence rocks, it can be predicted that oil and gas fields in these zones are associated mainly with Mesozoic age rocks. In the Middle Kura depression, the surface of the Mesozoic deposits lies at a depth of up to 4-5 km, therefore it is considered favorable for exploration. Due to this, the oil and gas prospects of the tectonic crushing zones was studied in the Mesozoic deposits as a prospecting object of the Middle Kura depression.
Extending the Hyades

description: We explore the implications of models of the Hyades moving group in which it has a resonant origin, for regions of the Galaxy beyond the Solar neighbourhood. We show that while models associated with different resonances can produce nearly identical substructure in the local velocity distribution, the velocity distribution away from the Solar neighbourhood has different properties for different models. In particular there is a variation between different models of where in Galactocentric radius the observed Hyades signal in velocity space is strongest, at a given Galactic azimuth. We note, however, that the uncertainties in currently available data, primarily due to uncertain distances to stars, hide these signatures rather effectively, meaning we are not yet able to determine which resonance is the cause of the Hyades.

description: As companies continue to globalize, manufacturers face the challenge of strategically adjusting their vertical integration and restructuring production and supply chains. This leads manufacturers to increasingly pursue two strategies of restructuring. On the one hand, in the form of outsourcing value-adding activities, the focus is being placed on the core competencies of the company's own production. As a result, the vertical range of manufacture within the company is decreasing, while outsourcing is becoming more and more important. On the other hand, companies are also pursuing the strategy of least possible dependency to secure production through regional procurement of resources and expansion of the necessary competencies by means of increased vertical integration. In order to understand the consequences and effects of these changes at the level of production planning and control (PPC), a model-based view is necessary for an expanded understanding of the processual context of these changes. The PPC is the essential steering instance of production. It combines long-term tasks, e.g. Plan Sales or Roughly Plan Resources, with short-term tasks, e.g. Schedule Throughput or Plan Resources in Detail. The main PPC task, Plan Sourcing, is an essential link with its tasks and procedures between the core processes of procurement and production in the company's internal supply chain. In the context of this paper, the PPC main task Plan Sourcing is to be considered in a model-based manner, which focuses on the selection and connection of suppliers as well as the general view of the supplier management of manufacturers. For this purpose, the effect on the PPC and the production logistic objectives variables is presented by means of the consideration of the tasks and possible procedures for the fulfilment of these PPC tasks. Utilizing collected findings, a process-related derivation for the synchronization of the affected areas of procurement and production is presented.
Unexpected radial trend of the iron abundance in a sample of monometallic Galactic globular clusters

description: We study the relationship between the iron abundance (IA) in red giant branch (RGB) stars and their radial distribution (RD) in Galactic globular clusters (GCs). We relied on publicly available archival data on IA in red giants (RGs) of GCs. We built a sample of ten target GCs in which the number of these RGs exceeded one hundred stars. In each GC of the sample, we compared the RDs of two sub-samples of stars, more iron-rich (IR) and more iron-poor (IP) than the clusters' mean values of [Fe/H]. Their RDs turned out to be different at statistically significant confidence levels in NGC 104 (47 Tuc), NGC 1851, NGC 3201, and NGC 6752 in the sense that the IP RGs were more centrally concentrated than their IR counterparts. In 47 Tuc, the difference is significant at a higher confidence level within the PRAD of R = 8.0', where the IA increases by Delta[Fe/H] ~ 0.03 dex toward the cluster outskirts. In the latter three GCs, Delta[Fe/H] ~ 0.05 dex. Interestingly, the V magnitude of the RGB bump and the horizontal branch was recently shown to fade outward in 47 Tuc and was suggested to originate from a He abundance trend. The fading caused by the IA trend is similar to that observed for the RGB bump. Although the difference between the RDs of IP and IR RGs is statistically insignificant in other GCs, NGC 288 is the only GC of the sample, in which IR RGB stars are formally more centrally concentrated. Interestingly, three of the four GCs are highly concentrated. (Abridged)

description: En esta investigación se estudió la emisión y secuestro del carbono en dos mesocosmos construidos simulando la calidad de agua de un humedal natural eutrofizado. El primer mesocosmos (M1) estuvo ausente de plantas acuáticas, mientras que el segundo mesocosmos (M2) estuvo plantado con Eichhornia crassipes. Como metodología se planteó un balance de masa en estado estacionario, donde se evaluaron flux de CO2 y CH4, y las entradas y salidas de carbono en el agua, esto se hizo con el objetivo de definir si las unidades experimentales actuaban como fuente o sumidero de carbono. El estudio se realizó en un periodo de tiempo de 85 días en horas entre las 11:00 a.m. y la 1:00 p.m. Como resultados, las medianas de los flux de CO2 fueron de 76 y de 12 mg.m-2.h-1 en M1 y M2; y las medianas de los flux de CH4 fueron de 1.19 y 0.69 mg.m-2.h-1 en M1 y M2. El balance de masa confirmo que M1 y M2 actuaron como sumideros de carbono, en ambos sistemas los flujos másicos de acumulación de carbono en los sedimentos fueron de 6.51 y 9.57mg C h-1. Adicionalmente se evaluaron los flux diarios de CO2 y CH4 en un periodo de 68 horas consecutivas. Los resultados obtenidos demostraron que M1 y M2 actuaron como consumidores de CO2 durante el día y como emisores de CO2 durante la noche; mientras las emisiones de CH4 presentaron una tendencia a disminuir en horas nocturnas. En este estudio se concluye que los humedales construidos y naturales son sistemas almacenadores de carbono, presentando un papel fundamental en la regulación de ese ciclo. Además la presencia de plantas acuáticas representa un factor importante, ya que acelera las tasas de captura de CO2 y la acumulación de carbono en los sedimentos.

description: A chain-like or a 1D crystal-like universe made of intersecting membranes in extra dimensions in a Randall-Sundrum scenario is studied. A background gravitational metric satisfying the right boundary conditions is considered to study the localization of the scalar, gauge and Kalb-Ramond field. It is found that the wave function for the fields are Bloch waves. The mass modes equations are calculated allowing us to show the zero-gap mass behavior and the mass dispersion relation for each field. Finally we generalize all these results and consider $q-$forms in the crystal membrane universe. We show that, depending to the dimension $D$, the form $q$ and the dilation coupling $λ$ the mass spectrum can be the same for the different bosonic field studied.

description: Most of the qualitative groundwater resources of Azerbaijan are concentrated in the GanikhAyrichay foothills. As a result of research conducted in this area, it was revealed that the GanikhAyrichay foothills has great prospects for water supply in Baku. According to earlier hydrogeological studies in Ganikh-Ayrichay foothills, widespread sources on the plains are associated with rocks of the fourth period, with gravel and various old rocks. Sources associated with the cliffs of the fourth period, are associated with groundwater rivers. Groundwater areas in the plains are mainly formed under the influence of natural and artificial factors. The role of natural factors in the plain is one of the main factors. Their area of great influence is surrounded by the foothills. The role of river cones and natural hydrological factors near them in the formation of the hydrodynamic regime of underground water should be emphasized. Drinking groundwater in the study area is widespread.

We show that the strength of this Kerr-nonlinearity, as well as the effect of the photon-pressure force can be enormously increased by modulating the strength of the nonlinear coupling. We present an electromechanical circuit in which this enhancement can be readily realized.

description: A protocol for the identification of ancestry informative markers (AIMs) from genome-wide single nucleotide polymorphism (SNP) data is proposed. The protocol consists of three main steps: (a) identification of potential positive selection regions via Fst extremity measurement, (b) SNP screening via two-stage attribute selection and (c) classification model construction using a naive Bayes classifier. The two-stage attribute selection is composed of a newly developed round robin symmetrical uncertainty ranking technique and a wrapper embedded with a naive Bayes classifier. The protocol has been applied to the HapMap Phase II data. Two AIM panels, which consist of 10 and 16 SNPs that lead to complete classification between CEU, CHB, JPT and YRI populations, are identified. Moreover, the panels are at least four times smaller than those reported in previous studies. The results suggest that the protocol could be useful in a scenario involving a larger number of populations.

description: In the field of the Russian Federation nuclear power facilities operation, special attention is paid to ensuring the safety of nuclear power plants and improving their economic efficiency. The development and implementation of methods for the optimal organization of the NPP operation is carried out. To solve these tasks, the application of the methodology of "reliability-centered maintenance" and "risk-oriented maintenance" is carried out at NPP power units. The implementation of these methodologies involves the operational reliability of equipment analysis and, based on the results of the analysis, planning of preventive maintenance and optimization of spare parts sets. The solution of these tasks is complicated by the fact that a significant part of the equipment has large operating time, and is on the verge of running out of resources. The paper solves the problem of optimizing the composition of spare parts for objects of aging type. A model for calculating the profit from the operation of equipment with spare elements is proposed. The Kijima-Sumita model is used as a model to describe the process of exhaustion of the object's operability. The developed model is investigated on simulation data.

description: Epitaxial Bi(111) films were subject to many and partly even controversial studies on the semimetal-semiconductor transition triggered by a robust quantum confinement. The residual conductance was ascribed to conducting surface channels. We investigated ultrathin crystalline Bi films on Si(111) as a function of film thickness d between 20 and 100 bilayers by means of electric transport measurements. Varying temperature and magnetic field, we disentangled two transport channels. One remains indeed metallic at all thicknesses investigated and exhibits a slightly increasing conductance as a function of d, whereas the second is activated with a d-1 dependence of the activation energy, indicating a quasiharmonic confining potential. Both channels reflect the electronic properties of the entire film and do not allow us to strictly separate surface and bulk states. While there is clearly no bulk conductivity, the activated channel is consistently described as electronic excitation into the partly occupied quantum well states, which are also responsible for the metallic conductance and preferentially located close to both interfaces of the film. © 2018 American Physical Society.

description: Electrical oscillators play a decisive role in integrated transceivers for wired and wireless communication systems. In this context the study of fully integrated differential VCOs has received attention. In this paper formulas for investigations of the stability as well as the amplitude of CMOS LC tank oscillators are derived, where an overall model of nonlinear gain elements is used. By means of these results we are able to present an improved design approach which gives a deeper insight into the functionality of LC tank VCOs.

description: Assuming that the parameter dependent evolution, as well as the measurements that are done for readout, of a quantum system that acts as the probe in a quantum limited measurement scheme are both fixed, we find the optimal initial states of the probe that will saturate the quantum Cramer-Rao bound. When the probe system is itself made of identical, elementary, two-level subsystems or qubits, we connect the optimal state of the N qubit probe to that of the one qubit probe. This is done for two different classes of dynamics for the probe qubits, one of which is entangling while the other is not. We study the limitations placed on the optimal initial state of the probe and the achievable measurement uncertainty by restrictions on the readout procedure that is applied on the probe qubits at the end of the measurement protocol.

description: Lineament analysis of space images can be successfully used for the purposes of formalized analysis and development of maps of geodynamic zoning with the ranking of the study area into areas that differ in the degree of relative geodynamic activity. As calculated indicators of geodynamic (neotectonic) activity, the density of faults, megacracks and other lineaments, expressed by their total length per unit area, was used. Therefore, the parameter "density of strokes" is taken as the basis for the taxonomic division of the study area into regions according to the degree of tectonic disturbance of the earth's crust. All constructions are implemented on the basis of lineament analysis included in the CATALIST software package (Canada) On the example of two seismically hazardous regions of the Northern Tien Shan (Almaty and Zhambyl), the distribution features and properties of lineament density parameters are illustrated, followed by the construction of maps of geodynamic activity. The lineament analysis of the DEM SRTM of the regional level of generalization made it possible to establish the main features of the geodynamics of the regions Zhambyl and Almaty regions at the present stage. The results obtained have proven their effectiveness and the ability to conduct an objective assessment of the seismicity of the territories, the reliability of which is confirmed by seismological and other ground-based observation data.

description: Code review is an important process in software engineering – yet, a very expensive one. Therefore, understanding code review and how to improve reviewers’ performance is paramount. In the study presented in this work, we test whether providing developers with explicit reviewing strategies improves their review effectiveness and efficiency. Moreover, we verify if review guidance lowers developers’ cognitive load. We employ an experimental design where professional developers have to perform three code review tasks. Participants are assigned to one of three treatments: ad hoc reviewing, checklist, and guided checklist. The guided checklist was developed to provide an explicit reviewing strategy to developers. While the checklist is a simple form of signaling (a method to reduce cognitive load), the guided checklist incorporates further methods to lower cognitive demands of the task such as segmenting and weeding. The majority of the participants are novice reviewers with low or no code review experience. Our results indicate that the guided checklist is a more effective aid for a simple review,while the checklist supports reviewers’ efficiency and effectiveness in a complex task. However, we did not identify a strong relationship between the guidance provided and code review performance. The checklist has the potential to lower developers’ cognitive load, but higher cognitive load led to better performance possibly due to the generally low effectiveness and efficiency of the study participants.

description: We study the formation of calcium carbonate, through the solid-gas interaction of amorphous Ca-silicate with gaseous CO2, at elevated pressures, and link this to the possible presence of calcium carbonate in a number of circumstellar and planetary environments. We use in-situ synchrotron X-Ray powder diffraction to obtain detailed structural data pertaining to the formation of the crystalline calcium carbonate phase vaterite and its evolution with temperature. We found that the metastable calcium carbonate phase vaterite was formed alongside calcite, at elevated CO2 pressure, at room temperature and subsequently remained stable over a large range of temperature and pressure. We report the formation of the calcium carbonate mineral vaterite whilst attempting to simulate carbonate dust grain formation in astrophysical environments. This suggests that vaterite could be a mineral component of carbonate dust and also presents a possible method of formation for vaterite and its polymorphs on planetary surfaces.

description: After establishing a fuzzy rule base using the interpolation result mechanism, arranging a fuzzy inference system is performed. The established system will infer about the level of risk using a fuzzy rule base and input statistics. In this work, the construction of the inference system has been determined using fuzzy rules interpolation. The construction determines the distances between input signals and relation functions based on if-then rules. The cross section α used here reduces the distance between input variables. In this work, interpolation is used to measure the distance between α-section fuzzy sets. Such economics issues as forecasting, planning, calculation of expected income are considered in uncertainty conditions, incomplete information conditions using interpolation.

description: Split-ring resonators (SRR) are simple electrical circuits that show a significant shift in resonance frequency even with the smallest changes in split capacitance, and thus in permittivity, electric conductivity, and dielectric losses of the split capacitor’s dielectric. Usually, the resonance frequency is derived from the frequency response, but recording the frequency spectrum takes a certain amount of time. Here, we present a new capillary split-ring resonator CaSRR with fast readout for liquid chromatography (LC), which is capable of accurately detecting very fast changes in split capacity. The proposed method is based on the detection of the transmitted signal at a single frequency that is analyzed by demodulation. The demodulated signal changes its amplitude depending on the shift of the resonance frequency. Our simple low-cost electronics enables an average sampling rate of 42 Hz with 128 averages of the demodulated signal and has a frequency stability of 840 mHz. Thus, a minimum change in permittivity of ∆εr,min = 11.26 × 10−3 can be detected. Finally, a chromatogram of one sugar (glucose) and one sugar alcohol (xylitol) is recorded using the SRR and is compared to a standard refractive index detector. © 2022 by the authors.
