Published: June 2021

Purpose
This study investigated the effects of visually presented speech envelope information with various modulation rates and depths on audiovisual speech perception in noise.

Method
Forty adults (21.25 ± 1.45 years) participated in audiovisual sentence recognition measurements in noise. Target speech sentences were auditorily presented in multitalker babble noises at a −3 dB SNR. Acoustic amplitude envelopes of target signals were extracted through low-pass filters with different cutoff frequencies (4, 10, and 30 Hz) and a fixed modulation depth at 100% (Experiment 1) or extracted with various modulation depths (0%, 25%, 50%, 75%, and 100%) and a fixed 10-Hz modulation rate (Experiment 2). The extracted target envelopes were synchronized with the amplitude of a spherical-shaped ball and presented as visual stimuli. Subjects were instructed to attend to both auditory and visual stimuli of the target sentences and type down their answers. The sentence recognition accuracy was compared between audio-only and audiovisual conditions.

Results
In Experiment 1, a significant improvement in speech intelligibility was observed when the visual analog (a sphere) synced with the acoustic amplitude envelope modulated at a 10-Hz modulation rate compared to the audio-only condition. In Experiment 2, the visual analog with 75% modulation depth resulted in better audiovisual speech perception in noise compared to the other modulation depth conditions.

Conclusion
An abstract visual analog of acoustic amplitude envelopes can be efficiently delivered by the visual system and integrated online with auditory signals to enhance speech perception in noise, independent of particular articulation movements.

Published: June 2021

AbstractPeripheral nerve injuries of the upper extremity can result from a wide array of etiologies, with the two most common being compression neuropathy and traumatic injuries. These types of injuries are common and can be psychologically, functionally, and financially devastating to the patient. A detailed preoperative evaluation is imperative for appropriate management. Traumatic injuries can typically be treated with local burial techniques, targeted muscle reinnervation, and regenerative peripheral nerve interfaces. Median nerve compression is frequently managed with complete release of the antebrachial fascia/transverse carpal ligament and/or use of flap coverage such as the hypothenar fat pad flap and local muscle flaps. Ulnar nerve compression is commonly managed via submuscular transposition, subcutaneous transposition, neurolysis, and nerve wrapping. In this review, we discuss the preoperative evaluation, surgical techniques, and advantages and disadvantages of each treatment modality for patients with compressive and traumatic upper extremity nerve injuries.

Published: June 2021

Hematite (α-Fe2O3) has become popular these days for their photocatalytic activities of water splitting. Metal-doped hematite materials are interesting as well for the bandgap engineering and for resolving fast charge–hole recombination. In this study, magnetism and ionic behaviors of rare manganese-doped α-Fe2O3/silica nanocomposites are investigated. These nanocomposites are prepared by the impregnation method with a mixture of metal halides, followed by rapid heating (30 °C/min) under air condition. When the molar ratio between FeCl3·6H2O and MnCl2·4H2O is 2.97, wasp-waisted hysteresis and ferromagnetism with the Curie temperatures of 56.1 and 58.0 K are observed for the nanocomposites annealed at 600 °C for the duration of 3 and 7 h, respectively, while dominant spin glass states are observed for the nanocomposites annealed at 500 °C. In x-ray diffraction patterns, mixed phases of α-Fe2O3 are identified, whereas crystalline metallic Mn or Mn oxides are hardly found. Electron energy-loss spectroscopy study indicates that Mn2+ is severely oxidized, and with this oxidation of Mn2+, Si becomes more metallic. When the molar ratio between Fe and Mn halides is 7.32, magnetism is affected by a small amount of γ-Fe2O3, and spin glass states and the competition between ferromagnetism and antiferromagnetism are observed in the long temperature range.
Motion estimation and correction in SPECT, PET and CT
Authors: Kyme Andre Z , Fulton Roger R 
Published: June 2021

Abstract
Patient motion impacts single photon emission computed tomography (SPECT), positron emission tomography (PET) and x-ray computed tomography (CT) by giving rise to projection data inconsistencies that can manifest as reconstruction artifacts, thereby degrading image quality and compromising accurate image interpretation and quantification. Methods to estimate and correct for patient motion in SPECT, PET and CT have attracted considerable research effort over several decades. The aims of this effort have been two-fold: to estimate relevant motion fields characterizing the various forms of voluntary and involuntary motion; and to apply these motion fields within a modified reconstruction framework to obtain motion-corrected images. The aims of this review are to outline the motion problem in medical imaging and to critically review published methods for estimating and correcting for the relevant motion fields in clinical and preclinical SPECT, PET and CT. Despite many similarities in how motion is handled between these modalities, utility and applications vary based on differences in temporal and spatial resolution. Technical feasibility has been demonstrated in each modality for both rigid and non-rigid motion but clinical feasibility remains an important target. There is considerable scope for further developments in motion estimation and correction, and particularly in data-driven methods that will aid clinical utility. State-of-the-art deep learning methods may have a unique role to play in this context.

Published: June 2021

Abstract
Carrying out rituals in the church hall of the cathedral is accompanied by a significant release of various hazards from parishioners and staff (heat, water vapor, carbon dioxide), when burning candles, from the use of censers and lamps (heat, carbon dioxide, fumes, soot, soot, water vapor), from consecration and solar radiation through external enclosures (heat). In the article, a local exhaust ventilation system with the use of umbrellas installed above the candlestick tabletop is proposed for trapping and removing harmful emissions from burning candles in a worship hall. To calculate air changes, it is important to have data on the amount of harmful substances emitted in the church hall of the cathedral. It is known that in the central part of the cathedral during the warm period of the year in the hall of worship at the permissible internal air temperature from 12 to 16 ° C and the optimum temperature from 14 to 16 ° C, one person emits an average of 50 g / h of water vapor. In the cold period of the year, when the permissible internal air temperature in the worship hall is from 12 to 16 ° C and the optimal temperature is 14 to 16 ° C, each parishioner emits on average up to 40 g / h of water vapor. Heat release from one person in full heat reaches 80 W in the warm season, and up to 100 W in the cold.

Abstract
Nowadays a huge number of industrial buildings constructed in the last century need restoration. Structures with brick walls are in the list. The reason for this is the appearance of cracks, breaks, spalls, cavities, holloes and other discontinuities of brickwork; wall deformations; stratification of brickwork rows; humidification of walling, weathering and leaching of mortar; loss of individual bricks; damage to protective and finishing layers; efflorescence on the surface of brickwork and many other things.
The causes of such defects can be the following: unsatisfactory operating conditions; errors at the design stage; low quality of the used construction material; substandard work; differential settlement of walls foundation; violation or lack of wall waterproofing; natural aging of masonry and other negative factors.
In this work the object of the inspection was a brick wall of the main building of the sugar factory, which was put into operation in 1962.The inspection results showed that the condition of the load-bearing brick wall of the sugar factory main building, taking into account the scope and danger of defects, the degree of physical and moral wear of structures, as well as a number of other factors, can be considered unsatisfactory (limited working capacity) and the building can be regarded suitable for reconstruction and further operation.

The work is aimed at identifying the most effective methodology for short-term forecasting of energy consumption concerning intervals of 1 hour to 1 week based on the employment of im-proved fuzzy recurrence and long short-term memory neural networks. The object of research is a residential area with an uneven consumption of electrical energy. The article discusses methods for forecasting electrical load on the example of a residential area. The existing methods of forecasting were analyzed and the day-ahead and intra-day power forecast were reviewed. The list of relevant sources was presented.
On the basis of the reviewed literature in this area, the most effective and modern methods were identified that allow determining the consumption of electrical loads in residential and industrial buildings with an accuracy of 98 percent. Tables were developed reflecting the effectiveness of the considered techniques.
The time horizons of the forecast of electric energy consumption are considered. Four categories of load forecasting were identified: long-term forecasting with a forecast interval of more than one year; medium-term forecasting with a forecast interval from one month to one year; short-term load forecasting with a forecast interval from 1 day to several weeks.; operational forecasting, with a forecast interval from 1-2 hours to the end of the day.

Abstract
Solar power is almost a good idea for home owners interested in saving money on electricity costs and supporting a healthier environment. But there’s no denying that some homes are more well suited to solar power systems than others. Your sun exposure, roof, climate, even state policies can influence how well you’ll do with a residential solar power system.
It is true that the initial cost might be a bit heavy, but it makes more economic sense in the long run. This is a onetime expenditure that serves cost free for the next thirty years or so. And about its effectiveness, people should feel comfortable that the technology itself has been proven, as a reliable and clean energy source.
This article introduces the methodology and the results of an integrated design approach to optimize both structural system and building energy performance through architectural design process. The book titled Intelligent Design using Solar-Climatic Vision, introduced a number of practical and effective design approaches towards the creation of energy-efficient building façades as well as comfortable urban environments. Applying solar-climatic vision, especially during the procedure of optimizing tall structural systems, can develop sustainable frameworks that maximize thermal comfort while minimizing waste of resources.
Wear of vibrating disc working bodies of smoothing machines
Authors: Eliseev S V , Mamaev L A , Kashuba V B , Gerasimov S N 
Published: June 2021

Abstract
The issues of wear of disk vibrating working bodies of smoothing machines are considered. It is shown that during friction of the working body against the concrete mixture, mainly abrasive and less oxidative wear occurs. In this case, the amount of wear is proportional to the smoothing capacity of the working body, the operating time, the specific pressure of the working body on the surface of the concrete mixture and the coefficient taking into account the working conditions. It was found that the position of natural and forced vibrations of the working body on the smoothing process leads to significant changes in the magnitude and nature of the disc wear. It was determined that the general one-sided character of the disk depends on the parameters of forced vibrations generated by the working body. The presence of localized zones with an expressed wear of the disc was revealed. The latter reduces most significantly the quality of the surface treatment of the concrete mixture. The relationship between the presence of wear of localized wear zones and natural vibrations of the metal structure of the portal of the smoothing machine is shown. It is suggested that the issues of vibration protection (vibration isolation) in the broad sense of controlling the dynamic state of the smoothing machine as a technological complex are of decisive importance for the prevention or significant reduction of local localized wear of the working body.

Abstract
Effective management of real estate complexes, which determines the minimum cost of ownership of constructed and operated objects, implies at the present stage the active introduction of information modeling technologies into the project life cycle. At the same time, in all the variety of modeling software and modeling formats offered by the national and foreign markets, those that have advanced controllability and adaptability to the changing conditions of the design or actual construction stages are the most effective for the purposes of managing the capital intensity of a non-movable asset. The ARCHICAD software package, which is a recognized leader in architectural modeling software, contains the necessary standard and additional tools for creating parameterized objects - elements of a real estate object that have the required properties, significantly accelerating and simplifying the work on adapting the model and optimizing space-planning solutions created on its basis. The authors created a universal parameterizing library feature of wall panel of precast technology in private residential construction, which implements a modular approach to parametric modeling using encapsulation basic library features to upgrade effectively the panel, to implement the specification of resources, visualize technology, including the virtual reality environment, providing the necessary visibility when training for line personnel of the construction site and technical quality control of construction products. The estimation to reduce the complexity and growth performance of work implementation of the proposed approach when designing a wall barrier of low-rise residential buildings.

Typology of courtyards in apartment block development based on planning openness and permeability
Authors: Matiukhin A A , Anisimova L V 
Published: June 2021

Abstract
In the Russian Federation, the problem of creating a comfortable urban environment is of a national nature. The authors suggest paying attention to the courtyard in apartment block development as this area is one of the most important elements of the urban environment – a buffer space between the apartment and the city. As an important criterion for a comfortable environment is its safety, therefore, it is necessary to understand which courtyards form a sense of security in people, and which do not. The formation of a sense of security of residents is influenced by many different factors. Courtyards, having a different planning arrangement, create different conditions for the comfort of living inhabitants and the degree of use by other people. The authors propose the development of a typology of courtyard spaces based on a sense of comfort and security. As basic characteristics they propose to use: planning openness of the yard, which characterizes the degree of built perimeter of the yard, as well as the permeability of the territory, indicating the accessibility of this area for other residents and their activity. This typology will be the basis for further determining how each type affects the formation of a sense of security among residents and what measures from an architectural point of view can be applied to ensure the formation of this feeling.
System of maintaining parameters of air conditioning in orthodox cathedrals
Authors: Eremkin A I , Ponomareva I K 
Published: June 2021

Abstract
Calculating air exchange according to existing methods, dilutions of all heat surpluses and other hazards are taken into account. This leads to a significant overestimation of the amount of supply air and saving unreasonable costs. To solve the problem of cost optimization, the authors propose a displacement ventilation and air conditioning system. In this case, the supply air is supplied to the lower zone, where the congregation is located. In this case, it is proposed to calculate the air exchange for the assimilation of only part of the heat surplus and other harmful substances entering only the lower zone, up to 2,5 meters high from the floor level. The rest of the hazards are displaced by convective flow and supply air to the upper zone and removed to the outside. The proposed solution to the problem allows you to optimize the cost of ventilation and air conditioning in the halls of worship of Orthodox churches.

Published: June 2021

Abstract
The paper analyzes the properties of rocks with a shale structure, justifies the need to apply force in the direction of the lowest strength. The list of crushing equipment used in the process of obtaining cube-shaped crushed stone is given. It is established that the existing crushing equipment is not able to take into account the specific texture of the crushed materials and this does not allow obtaining cube-shaped crushed stone from shale materials. A description of the new design of the press-roll unit, which allows obtaining cuboid crushed stone from rocks with a shale structure, is given. The press-roll unit includes a device for directional feeding of shale materials to its working bodies, which create a force effect on the fed pieces of rock in the required direction. The design of the tooth of the working body is described, which allows to reduce significantly the replacement time of worn elements and reduce the bending loads acting on it. This leads to an increase in the reliability of the structure and reduces the metal consumption of repairs. A mathematical model of the directional movement of shale materials in a roll device is considered and an equation for calculating the required force is obtained. Graphical dependences of the influence of the roller installation angle and its horizontal and vertical displacement on the amount of deformation of the feed material layer are presented.

Abstract
The paper deals with the issues of technology of grouting binders of silicate materials with the use of waste from the processing of petroleum bituminous rocks. The optimal compositions of grouting solutions with the use of waste from the processing of PBR were studied.
The stability of the samples in aggressive environments of low-and high-base calcium hydrosilicates was studied. Technological processes for the production of grouting binders based on waste from the processing of PBR were justified and developed.
Grouting compositions, characterized by high quality were developed. The positive effect of mixing and storage of the tested cement mixtures containing up to 50% of PBR waste with sulfate solutions of Na 2SO 4 and MgSO4 salts on the studied technical characteristics of the grouting solution and cement stone was established.
A significant result is an improvement in the setting performance, an increase in strength without a significant deterioration in the adhesion of the cement stone to the drive pipe at a 5% salt concentration.
The research results provide recommendations for the development of weighted grouting cements using technogenic materials containing an increased amount of iron oxide.
