Banana (Musa spp.) is one of the world’s most important staple and cash crops. Despite accumulating genetic and transcriptomic data, low transformation efficiency in agronomically important Musa spp. render translational researches in banana difficult by using conventional knockout approaches. To develop tools for translational research in bananas, we developed a virus induced-gene silencing (VIGS) system based on a banana-infecting cucumber mosaic virus (CMV) isolate, CMV 20. CMV 20 genomic RNA 1, 2, and 3, were separately cloned in Agrobacterium pJL89 binary vectors, and a cloning site was introduced on RNA 2 immediately after the 2a open reading frame to insert the gene targeted for silencing. An efficient Agrobacterium inoculation method was developed for banana, which enabled the CMV 20 VIGS vector infection rate to reach 95% in our experiments. CMV 20-based silencing of Musa acuminata cv. Cavendish (AAA group) glutamate 1-semialdehyde aminotransferase (MaGSA) produced a typical chlorotic phenotype and silencing of M. acuminata phytoene desaturase (MaPDS) produced a photobleachnig phenotype. We show this approach efficiently reduced GSA and PDS transcripts to 10% and 18% of the control, respectively. The high infection rate and extended silencing of this VIGS system will provide an invaluable tool to accelerate functional genomic studies in banana.

Preparation of sophisticated delivery systems for nanomedicine applications generally involve multi-step procedures using organic solvents. In this study, we have developed a simple self-assembling process to prepare docetaxel-loaded hyaluronic acid (HA) nanocapsules by using a self-emulsification process without the need of organic solvents, heat or high shear forces. These nanocapsules, which comprise an oily core and a shell consisting of an assembly of surfactants and hydrophobically modified HA, have a mean size of 130 nm, a zeta potential of −20 mV, and exhibit high docetaxel encapsulation efficiency. The nanocapsules exhibited an adequate stability in plasma. Furthermore, in vitro studies performed using A549 lung cancer cells, showed effective intracellular delivery of docetaxel. On the other hand, blank nanocapsules showed very low cytotoxicity. Overall, these results highlight the potential of self-emulsifying HA nanocapsules for intracellular drug delivery.

Published: August 2019

A mass spectrometric analysis platform has been developed to determine whether glycosylation patterns of alpha-1 acid glycoprotein (AGP) could be used as a marker for early detection of hepatocellular carcinoma (HCC) in different etiologies, i.e. non-alcoholic steatohepatitis (NASH), alcoholic liver disease (ALC), and hepatitis C virus (HCV). MALDI-MS profiling of N-glycans of AGP purified from 20 μL of patient serum in HCC (n = 72) and liver cirrhosis (n = 58) showed that a unique trifucosylated tetra-antennary glycan (m/z 3490.76) was predominantly identified in HCCs but was absent in healthy subjects and the majority of cirrhosis patients. Receiver operation characteristic (ROC) curve analysis showed that the trifucosylated N-glycan of AGP (triFc_AGP) could differentiate HCC from cirrhosis with an area under the curve (AUC) of 0.707, 0.726 and 0.751 for NASH, ALC and HCV, respectively. When combining triFc_AGP with INR and AFP, the panel had the greatest benefit in detection of NASH-related HCCs, with a significantly improved AUC of 0.882 for all NASH HCCs and 0.818 for early NASH HCCs compared to AFP alone (0.761 and 0.641, respectively). Moreover, triFc_AGP could serve as a potential marker for monitoring AFP-negative HCC patients.

Distributed finite‐time control for Markovian jump systems interconnected over undirected graphs with time‐varying delay
Authors: Xue Xiaojuan , Xu Huiling , Xu Li
Published: August 2019

This study considers the problems of stochastic finite‐time stability analysis and distributed finite‐time control for Markovian jump systems interconnected over undirected graphs with time‐varying delay. First, the concepts of the well‐posedness, stochastic finite‐time boundedness and contractiveness for the class of systems are introduced, and the control problem formulation is presented. Then, a sufficient condition on the well‐posedness, stochastic finite‐time boundedness and contractiveness for the resulting closed‐loop systems is proposed by a set of non‐linear matrix inequalities in some given finite‐time interval. For decoupling this non‐linearity, a sufficient condition on the existence of a mode‐dependent distributed dynamic output feedback controller is established in terms of linear matrix inequalities with some fixed parameter. Moreover, the obtained controller, which not only inherits the structure of the plant but also has the same jumping process as the plant, can guarantee that the closed‐loop system is stochastic finite‐time bounded and contractive in some given finite‐time interval. Furthermore, an algorithm is presented to obtain the parameters of such controllers. Finally, a numerical simulation is presented to show the validity of the proposed method.
Incorporating iris, fingerprint and face biometric for fraud prevention in e‐passports using fuzzy vault
Authors: Bobkowska Katarzyna , Nagaty Khaled , Przyborski Marek
Published: August 2019

A unified framework which provides a higher security level to e‐passports is proposed. This framework integrates face, iris and fingerprint images. It involves three layers of security: the first layer maps a biometric image to another biometric image which is called biostego image. Three mapping schemes are proposed: the first scheme maps single biometric image to single biostego image, the second scheme maps dual biometric images to single biostego image, the third scheme divides the biometric image into sections and maps each section to different biostego image. A mapping function maps the intensity value of each pixel in the biometric image to pixels with same intensity in the biostego image. A representative pixel is randomly selected from the set of pixels, and its coordinates are recorded in the location map of the biometric image. In the second layer, the location map is encoded using fingerprint fuzzy vault. In the third layer, the encoded location map is hidden in the biostego image using steganography technique. The biostego image which contains the encoded location map is stored in the e‐passport's memory. Keeping the mapping scheme secret and by using the fingerprints fuzzy vault to encrypt location map, the proposed approach provides higher level of protection against fraud.
Fractional‐integral‐operator‐based improved SVM for filtering salt‐and‐pepper noise
Authors: Jia Xiaofen , Guo Yongcun , Zhao Baiting , Huang Yourui
Published: August 2019

To protect edge and texture information, when removing salt‐and‐pepper (SP) noise in grayscale images, a support vector machine (SVM) denoising method is employed. First, a mapping relation between the neighborhood signal pixels and the central pixel is designed. The size of the neighborhood is a 5 × 5 region, with a signal pixel in the center. In this region, a 25‐dimensional input sample is constructed using the correlation between the neighborhood pixels and the eight‐direction fractional integral operators. The center signal pixel acts as the corresponding output sample to provide a training sample. Then, the SVM is trained with all training samples, and the SVM denoising model is obtained. Next, the center pixel value is estimated using the SVM denoising model in every 5 × 5 region with a noise pixel in the center. Finally, the noise pixel values are replaced with the estimated values of the SVM. The experiments demonstrate that the best denoising effect is obtained when the fractional integral order is in the range of 1.8 ± 0.1. The proposed method produces a visually pleasing denoised image and obtains superior image quality assessment indicators. Our method has significant advantages compared with state‐of‐the‐art denoisers when a low level of noise is present.
Learning‐based method for lane detection using regionlet representation
Authors: Chen Yuxuan , Chen Wei‐Gang , Wang Xun , Yu Runyi , Tian Yan
Published: August 2019

Lane detection is an important enabling or enhancing technology for many intelligent applications. A marker line can be segmented into several image blocks, each of which contains lane marking in the centre. This study proposes a learning‐based method for lane localisation via detecting and grouping such image blocks. The authors model the marking class using regionlet representation, in which each image block is regarded as a region and is represented by a group of regionlets. A region feature composed of the features extracted from the regionlets contributes a weak classifier. A cascade structure detector is then trained for lane detection. At early stages, it rejects as many negatives as possible. Each layer of the cascade detector is a strong classifier, which consists of several weak classifiers. A real AdaBoost algorithm is adopted to select the most discriminative features and to train the classifiers. Since the use of regionlet features allows desired performance with only a few weak classifiers and the dimensionality of the features is significantly reduced by principal component analysis, the computational burden of their algorithm is much lower than other learning‐based methods. Experiment results demonstrate the computational efficiency and robustness of the method.

Authors: Jhajharia Tejpal , Tiwari Vivekanand , Bhatnagar Deepak
Published: August 2019

Here, a novel geometry of dual‐band polarisation reconfigurable patch antenna is presented. The proposed prototype design consists of two orthogonal arms as a patch, an inclined slotted asymmetric pentagonal‐shaped ground plane and a PIN diode with a biasing circuit. The polarisation reconfiguration is controlled via ON/OFF states of the PIN diode. The unique feature of the proposed antenna design is that it provides polarisation reconfiguration without considerable deviation in −10 dB impedance bandwidth (IBW) frequency response. The proposed antenna has a measured −10 dB IBW of 49.28% (3.96–6.55 GHz) and 41.47% (4.3–6.55 GHz) in the ON‐state and OFF‐states of the PIN diode, respectively. In the ON‐state of the PIN diode, the antenna exhibits a dual‐band circular polarisation. The first 3 dB axial ratio (AR) band is 4.5% (4.3–4.5 GHz) and the second 3 dB AR band is 17.69% (5.1–6.09 GHz). The proposed antenna exhibits almost uniform gain over the entire operating axial‐ratio bandwidth, with peak CP gain of 2.8 dBic. The suggested antenna has a wide −10 dB IBW, and it is suitable for C‐band wireless applications.

Authors: Berber Zakia , Kameche Samir , Benkhelifa Elhadj
Published: August 2019

A phase‐locked loop (PLL) frequency synthesiser is designed for 5G E‐band frequency. ADF4155‐PLL chip with an external (loop filter, prescaler, VCO and an external reference oscillator) is simulated using the ADIsimPLL tool. With a third‐order passive filter having 1 MHz loop bandwidth and 45° phase margin, simulation results show that the proposed synthesiser achieves a total phase noise (PN) of −81.50 and −115.7 dBc/Hz at 100 kHz and 10 MHz, respectively, for (71–76 GHz) and −80.39 and −114.7 dBc/Hz at 100 kHz and 10 MHz, respectively, for the highest (81–86 GHz) 5G frequency range even if −160 dBc/Hz VCO noise floor and −170dBc/Hz reference PN floor are integrated in the design. Also, the performance of the system in terms of RMS jitter and reference spurs are verified. The proposed synthesiser for 5G application presents very low reference spurs (−113, −112 dBc) at 50 MHz offset frequency and low RMS jitter (0.39, 0.40 ps) for 70 and 80 GHz frequency band, respectively.
Stochastic risk‐based flexibility scheduling for large customers with onsite solar generation
Authors: Angizeh Farhad , Parvania Masood
Published: August 2019

This study proposes a two‐stage stochastic optimisation model to co‐optimise the onsite flexibility resources of large customers with the decisions to purchase power from bilateral contracts and forward energy market, while considering the uncertainty of onsite solar generation and market prices. In addition to onsite solar generation, the proposed model integrates the energy flexibility provided by the customers’ flexible loads, onsite energy storage and onsite dispatchable generation. The uncertainty of onsite solar generation and market prices are characterised by autoregressive integrated moving average models, which are used to generate scenarios for the proposed stochastic optimisation model. The proposed two‐stage stochastic optimisation model, formulated as a mixed‐integer linear programming problem, minimises the expected energy procurement cost of the customers by optimising the first and second stage decisions. The first stage decisions include the utilisation of bilateral contracts, flexible loads and onsite energy storage and dispatchable generation, while decisions to purchase power from, and selling excess solar power to the energy market are optimised in the second stage. The proposed model integrates conditional value‐at‐risk as a risk measure that would enable the customers to manage the financial risks associated with the uncertainty of onsite solar generation and market prices. The proposed model is implemented on a test large industrial customer, where the advantages of the proposed model are investigated through multiple case studies.
Flying‐start and continuous operation of a permanent‐magnet wind generator based on discontinuous currents, discrete second‐order sliding‐mode observer and phase‐locked loop
Authors: Jukić Filip , Pravica Luka , Bariša Tin , Sumina Damir
Published: August 2019

In wind energy conversion systems of type 4, the critical operating point in permanent‐magnet generators (PMGs) is the moment of switching on the generator‐side converter (GSC). The induced back‐electromotive force (EMF) acting on PMG terminals can cause inrush currents if the synchronisation between PMG and GSC is not done well. The main condition for achieving a satisfying synchronisation is to know the rotor angle, rotating speed and induced back EMF before the GSC is switched on. This synchronisation together with the switching on of the GSC is called the flying start of a PMG. In this study, a novel sensorless PMG flying‐start method is proposed to ensure good synchronisation. The flying‐start method is based on an extended flux PMG model in a rotating reference frame with a discrete second‐order sliding‐mode observer and a phase‐locked loop controller during the discontinuous operating mode. This is based on discontinuous currents, which are induced because of the PMG rotation caused by wind energy. The proposed method ensures the operation of PMGs in the continuous operating mode as well. The effectiveness of the proposed method is verified on saturable models of low‐ and high‐power surface and interior PMGs through simulations in Simulink and Piecewise Linear Electrical Circuit Simulation (PLECS).
Designing lightspace in contemporary architecture
Authors: Nasybullina Renata , Slastenin Petr , Fadeev Artem
Published: August 2019

Daylight has a significant impact on the perception of the building space. The term “lightspace” is introduced to determine phenomena of sensorial perception of architectural object’s indoor space and four different components of lightspace, such as functional, architectural and artistic, light-technical and visual, are considered. Further, three groups of architectural and artistic design techniques were estimated: based on space modeling (organisation of lightspaces in the building structure, organization of multi-light spaces, plasticity organization of lightspace, methods of natural light penetration through the shell of the building), light modeling (the distribution of light in space and its spectral composition), and time modeling (light dynamic, transformation of the building parts, movement of people in the place). Attention is drawn to relationship between diverse lightspace design techniques and architectural practice.

Fire extinguishing in with polydisperse foam of high multiplicity
Authors: Melnikov Artem , Vlasov Nikolay
Published: August 2019

Risk of fire and smoke dangers are greater in high-rise rather than low-rise buildings. Use of high expansion foam delivered through elevator shafts can prevent or reduce smoke and fire damage and injury in high-rise buildings. Injection of foam with high multiplicity due to structural rigidity can accumulate between floors of buildings to prevent the spread of flame and smoke. Reaching an area of high-intensity flame, this foam is destroyed, resulting in the absorption of energy from the upward flow of products of combustion.
Methods for calculating the reliability and energy efficiency in the construction of real estate
Authors: Manukhina Lyubov
Published: August 2019

Organizational and technological reliability in the construction industry is the ability to maintain performance parameters within specified limits and to obtain a planned result under given production conditions. Carrying out repair and reconstruction works always requires large resource costs, so it is necessary to increase the efficiency of using the work with the application of new approaches to the organization of repair and reconstruction works at the real estate. To do this, it is necessary to improve the efficiency of managing a complex of works on the preservation and reproduction of real estate. It is necessary to effectively improve organizational and technological reliability with the help of competent mathematical tools to justify the strategy of repair work. For reliable functioning of the construction strategy, it is necessary to take into account the loss of reliability during repair and reconstruction work at the real estate. It is at this point that this article is based.

Improving construction duration forecasts and management of construction operations
Authors: Dadar Aldynkys , Bolotin Sergey , Malsagov Aslan , Oolakai Zita
Published: August 2019

To address the relevant construction challenges, it is necessary both to improve the existing construction duration forecasting methods and to develop optimal construction management methods. That being said, effective implementation of general management functions is defined by information interaction between management subjects and objects as a system bringing together construction management stakeholders. Very often the construction practice reveals that some contractors’ statistics related to execution of works can altogether be absent or be unrepresentative. With this fact borne in mind, the authors of this material focus on using nonparametric statistic or distribution-free methods. On the other hand, the lack of representative statistical data indirectly indicates to ineffective management of the construction process. The article shows that the possible solution of the construction duration forecasting task is the methodology of neural and statistical simulation. We suggest that the efficiency of expeditious construction management should be assessed by calculating the information entropy, while regulatory action aimed at increasing managerial energy must be achieved by optimally allocating costs among the various elements oriented towards resource-based management. The presented model of improving construction duration forecasts allows the optimization of construction regulation process, which must increase its organizational and technological reliability.

Authors: Chulkov Vitaly , Yurgaytis Alexey
Published: August 2019

Today, cyberphysics is considered as an interdisciplinary science and one of the important directions of modern technical development in the reorganization of the construction industry. Initially, the term "cyberphysics" meant technical systems with computational tools embedded in them. In these systems, the human operator used different channels of information transfer in the design and management processes. Over time, in the framework of the scientific and technical direction of "cyberphysics", the problems of ensuring its own state space and its parameters began to be considered. In the article, the concepts of homeostat (stable state of the building system) and an intelligent building system have been introduced and formally defined, which are used in the quantitative assessment of the quality of building systems of design and management. As the result of research, the practical task of developing an apparatus for infographic modeling has been set, the application of which would become the basis for technical regulation in certain segments of innovative technologies for construction reorganization (for example, in the housing and communal complex of the Russian Federation).

Big data sets in construction
Authors: Kagan Pavel
Published: August 2019

The paper studies the processing of large information data arrays (Big Data) in construction. The issues of the applicability of the big data concept (Big Data) at various stages of the life cycle of buildings and structures are considered. Methods for data conversion for their further processing are proposed. The methods used in the analysis of "big data" allow working with unstructured data sets (Data Mining). An approach is considered, in which the analysis of arbitrary data can be reduced to text analysis, similar to the analysis of ordinary text messages. At the moment, it is important and interesting to isolate non-obvious links present in the analysed data. The advantage of using big data is that it is not necessary to advance hypotheses for testing. Hypotheses appear during data analysis. Dependence analysis is a basic approach when working with big data. The concept of an automatic big data analysis system is proposed. For data mining, text analysis algorithms should be used, and discriminant functions should be used for the main problem to be solved (data classification).

Authors: Gusakova Elena , Ovchinnikov Alexey
Published: August 2019

In the context of the general trend to accelerate change, the life cycle of a construction object, analysis and design of its stages becomes an actual object of scientific research in the field of construction. The subject of the study becomes the information model of the life cycle of the building. It is studied and modeled on the basis of the concept of real estate development and using the methods of project analysis of the construction project. With the help of BIM-modeling tools, mandatory stages and possible phases of the life cycle of a building object can be represented as hierarchically and sequentially related information flows, in which the attributes of each stage of the life cycle are formed under the influence of the preceding stages and of special factors for the considered stage. On this basis, an analysis of the characteristics was carried out, and the structure of simple and complex construction works was developed, which allows determining for each stage of the life cycle of a construction object: interconnection of information flows, composition and content of the information model of the building required for the work of specialists.

One of the main ways to shape the competitiveness of an enterprise is to reduce production costs. A significant component of such costs are the costs of energy consumption. Therefore, the ability to control energy saving in the economic activity of the enterprise is a task of great importance. The development of energy-saving technologies, which are low-cost for this type of resource of energy-consuming machine systems, is conducted, as a rule, on a project basis, and the implementation of such projects must be carried out according to certain rules. An important principle is the need to determine the rational volumes of all types of resources attracted to the project. The solution to this problem is very difficult and time consuming. The use of economic and mathematical models of various classes can help reducing the risks and complexity of solving the problem. One of the promising types of design modeling of the development of both energy producing and energy consuming enterprises is S-modeling or modeling based on logistic dynamics. Today, undeservedly little attention is paid to this type of model. The proposed article presents methodological developments that can increase the interest in using this type of modeling in practice. Methods and models proposed in the work were tested on a really implemented project of organizational development, which increases their value.

Published: August 2019

The need to improve the investment climate and form a new efficient system of economic relations requires the use of new economic mechanisms, among which leasing is one of the most effective for the development of the real economy. The paper deals with the risk management problems of leasing companies and leasing projects. It discusses the activities of specialized leasing companies and methods of risk management of leasing transactions based on basic risk management processes in project management, analyzes various types of risks associated with lessors, discusses methodological approaches to managing risks of leasing companies in general, and economic and mathematical methods for assessing risks of default for lessees. An econometric model has been created that allows predicting confidence in the payment of lease payments or the default of the lessee. The obtained model excludes the subjective methods for assessing the potential client's solvency and is less labor-intensive in comparison with the scoring model and the method of expert assessment.

A modern economy requires building effective innovation systems. The formation of national and regional innovation systems should be closely linked. Therefore, it is necessary to deeply understand and take into account the peculiarities of the formation of regional systems in the national economic space. This is especially true for the Russian Federation due to the specificity of the administrative system and existence of significant disparities between the regions. Regional innovation systems are actively being developed, just as in more developed regions and less developed countries. Despite the country’s internal conditions, this should be a unified process. Therefore, it is particularly important for the issues of interregional cooperation to eliminate asymmetries and synchronise changes.

One of the main methodological principles of modern economics is the separation of the positive and normative study area. Traditionally, the dominant regulatory approach is associated with a "pre-scientific" era - with the economic views of antiquity and the Middle Ages. Thus, the very evolution of the economic analysis can be considered as a process of gradual replacement of a regulatory elements and achieve ever greater degree of objectivity of research. In this paper, the economic theory of multi-dimensional stock and commodity market in the green economy is considered in detail. The current state of the theory of markets and market mechanisms is discussed. The research methodology and theory of multi-dimensional stock and commodity market in the green economy, adapted to the real conditions of the transformation of the Russian economy, are substantiates. Various forms of heterogeneity of market processes are identified and classified, including factors of demand, supply and competitiveness arising from the terms of the transformation of the economy attracting green investment.

The article studies the economic essence of depreciation accounting. Various points of view are examined by the authors on the issue of the economic nature of depreciation deductions and the order of their reflection in accounting and reporting. Special attention is paid to the method of cost allocation for the acquisition of assets on the basis of their contribution to net income. It is established that in accounting, the compliance of two financial flows – income and expenditure of the company, and the comparison within specific reporting periods should be ensured. It is proposed to apply a method for reserving amounts of depreciation depending on the result of the financial activities of the company. The mechanism of redundancy is described in detail, the essence of which lies in the emergence of two streams of depreciation. It is proved that the proposed method of redundancy of depreciation deductions will take into account the trends in the income of the company’s activities and fully implement the principle of matching revenues expenses incurred.

A review of the theoretical foundations of the main approaches to the description of traffic flows has been carried out. A key parameter is proposed for comparing costs when driving on ordinary roads and high-speed toll roads. The possibilities for determining the quantitative assessment of this parameter using the tools of the theory of traffic flows are considered. A new technique for solving the task with the help of modern information technologies is proposed. Additional parameters are identified, and measures are indicated for further work and improvement of the proposed method.
