Published: May 2019

The article discusses the possibility of using the criteria of energy saving, cost and comfort as an estimate criterion in the analysis of information modeling technologies for low-rise buildings at the stages of design, implementation and operation. The insulation systems of low-rise buildings, including frame type, are considered as an object of study.
Different types of insulation systems of frame buildings are considered and, as a result, the expediency of using rolled polyethylene foam as an insulating material is established. Its use allows to form a seamless insulating sheath with minimization of heat transfer bridges, as well as to eliminate the use of additional wind-proof and vapor-insulating membranes.
The regularities of the influence of operating factors on the thermal resistance of the insulating shell are established. The data obtained as a result of the implementation of experimental studies allow us to state that low water absorption and low vapor permeability of the insulating layer exclude the possibility of its wetting and degradation of heat-shielding parameters. The stability of the properties of the insulation sheath and the construction of the walls as a whole is ensured during the entire period of operation.

Cellular glass by its composition, structure and technical parameters is a high-performance multifunctional material, and its use in construction and engineering is extremely important.
The problem of developing cellular glass power consumption technology on the base of natural amorphous aluminosilicates and silica rocks in a single technological process, combining the synthesis of a given glass composition and the formation of its cellular structure is solved by introduction of a nanodispersed modifier into the rock and by the mechanical activation of the charge, creating an impact possibility in the system at the atomic-molecular level.
With the involvement of a complex modern theoretical and experimental methods, the processes of glass wool rock modifyed sintering and expanding were investigated, which served as a base for creating the cellular glass technology in the form of products and granules.
The study of the secondary glass synthesis dynamics during sintering of volcanic glasses with sodium hydroxide solution showed that the hydrated amorphous neoplasms of sodium silicates synthesized at low temperatures and silica aluminosilicates with temperature rise gradually enriched with silica and formed hydrated secondary glasses, the dehydration of which expanded the mass upon reaching the pyroplastic state.
Power consumption technologies of the new type cellular glasses based on the volcanic glass-wool and other amorphous silicate rocks, which allow to combine the processes of synthesis of low-melting glass and its expansion by sintering are challenging for the production and for application in construction and engineering.

The article gives the method of calculation of water storages dam at hydro technical accidents.From natural disasters floods (flooding of water in the area and settlements) by the frequency of occurrence of the phenomenon, the area of distribution and the annual material damage ranked first. Moreover, in recent years, the world has seen an increase in the number and extent of floods and the associated social and economic losses. Both at present and in the foreseeable future, floods as a natural disaster cannot be completely prevented everywhere and everywhere, they can only be weakened, localized and with timely warning to minimize material damage. Therefore, one of the largest floods in recent years, that occurred in the West Kazakhstan region in the spring of 2011 and which took place without casualties, resulted in the allocation of more than 19 billion tenge in damage recovery from damage. Unplanned and inconsistent with general measures during floods and floods, the descent of these reservoirs can exacerbate the effects of flooding. The technical condition of the channel dams is especially dangerous. In case of possible accidents on these dams, many settlements, thousands of enterprises, millions of hectares of agricultural land can get into the affected area.Based on the results of full-scale leveling surveys, forecasting calculations of the breakthrough of the water reservoir dams of Bartogay, Kapshagay and Kurty hydrounits have made.Attached graphics show a dependence of water consumption at the dam breakthrough on the distance from the dam gates.

Published: May 2019

Abstract
Purpose The accuracy of internal carotid artery stenosis (ICAS) quantification depends on the method of stenosis measurement, impacting therapeutic decisions and outcomes. The NASCET method references the stenotic to the distal ICAS lumen, the ECST method to the local outer and the common carotid artery (CC) method to the CC diameter. Direct morphometric stenosis measurement with four-dimensionally guided three-dimensional ultrasonography (4D/3DC-US) demonstrated good validity for the commonly used NASCET method. The NASCET definition has clinically relevant drawbacks. Our purpose was to investigate the validity of the ECST and CC methods.
Materials and Methods 4D/3DC-US percent-stenosis measures of 103 stenoses (80 patients) were compared to quantitative catheter angiography and duplex ultrasonography (DUS) in a blinded fashion.
Results The 4D/3DC-US versus angiography intermethod standard deviation of differences (SDD, n = 103) was lower for the CC method (5.7 %) compared to the NASCET (8.1 %, p < 0.001) and ECST methods (9.1 %, p < 0.001). Additionally, it was lower than the NASCET angiography interrater SDD of 52 stenoses (SDD 7.2 %, p = 0.047) and non-inferior for the ECST method (p = 0.065). Interobserver analysis of equivalent grading methods showed no differences for the SDDs between angiography and 4D/3DC-US observers (p > 0.076). Binary comparison to angiography showed equal Kappa values > 0.7 and an accuracy ≥ 85 % for the NASCET and CC methods, higher than for the ECST method. The binary accuracy of ICAS grading did not differ from DUS for all methods.
Conclusion The new 4D/3DC-US CC method is an accurate and well reproducible alternative to the NASCET and ECST methods and offers potential for clinical application.
Activity Profiles by Position in Youth Elite Soccer Players in Official Matches
Authors: Pettersen Svein Arne , Brenn Tormod 
Published: May 2019

AbstractIn order to investigate activity profiles and external load patterns in elite youth soccer players, we studied high-intensity activity patterns, maximum running speed, and temporary and
end-of-match decline in external load in 54 U17 players (96 match observations) over a full season of official match play.Wide midfielders covered most high-intensity running (HIR) distance (1044.2 m), most sprinting distance (224.4 m), and the highest number of accelerations (185.2); center defenders
had the lowest values for these activities (508.3 m, 85.1 m, and 119.0), respectively. Wide midfielders had the highest and center defenders had the lowest maximum speed (30.3 km · h − 1
and 28.6 km · h − 1), respectively. During the matches, players in all playing positions displayed a significant drop in HIR distance, sprinting distance, and number of accelerations. This was especially pronounced in the 5 min following the 5-min peak period and in the last 5-min period for sprinting distance.There are substantial differences in activity profiles by positions, but all players show temporary and end-of-match drop in external load. The variation in activity profiles by playing
position in this study may aid in the design of training programs. The considerable end-of-match drop in external load observed raises the question of the favorability of 90 min match times for U17 players.

Authors: McNulty Beth , Schutt Christopher A. , Bojrab Dennis , Babu Seilesh 
Published: May 2019

Objective To compare outcome data for surgical approaches in the management of a middle cranial fossa encephalocele or cerebrospinal fluid (CSF) leak and, secondarily, to evaluate the role of obesity and the etiology of the defect.
Design Retrospective
Setting Quaternary referral center
Participants The study included 73 patients who underwent surgical repair of middle cranial fossa tegmen defects, two of which underwent bilateral repair.
Outcome Measures Demographic characteristics, clinical presentation, etiology, imaging, audiometry, surgical findings, method and material for repair, and postoperative course.
Results Fifty cases were spontaneous in origin, 2 were iatrogenic, and 23 were because of chronic otitis media. Of the 50, 18 underwent middle fossa craniotomy, 29 underwent a transmastoid approach, and 28 underwent a combined approach for repair. A postoperative CSF leak was seen in five patients: one who had undergone a transmastoid approach and four after a combined approach. There was no significant difference between the three approaches and risk of postoperative CSF fistulae. Two of the CSF fistulae resolved after a lumbar drain, and the remaining three patients required revision surgery.
Conclusions Middle cranial fossa tegmen defects are most commonly seen in obese females and are spontaneous in origin. The most common location was the tegmen mastoideum, and these defects were most commonly repaired through the transmastoid approach, with no greater risk of recurrence.

Published: May 2019

Introduction Preoperative high-resolution computed tomography (HRCT) is essential in patients undergoing transsphenoidal surgery to identify potential high-risk anatomic variations. There is no consensus in the literature, as to which grading system to use to describe these variants, leading to inconsistent terminology between studies. In addition, substantial variability exists in the reported incidence of anatomic variants. In this study, we performed an institutional imaging analysis and literature review with the objective of consolidating and clearly defining these sphenoid sinus anatomical variations. In addition, we highlighted their surgical implications and propose a checklist for a systematic assessment of the sphenoid sinus on preoperative CT.
Methods Review of the literature and retrospective analysis assessing several imaging parameters in 81 patients who underwent preoperative HRCT imaging for endoscopic transsphenoidal tumor resection from January 2008 through July 2015 at Rush University Medical Center.
Results The most common sphenoid pneumatization patterns were sellar (45%) and postsellar (49%) types. Anterior clinoid process (ACP) pneumatization was seen in 17% of patients with high concordance of ipsilateral optic nerve (ON) protrusion. ON protrusion and dehiscence was present in 17 and 6% of patients, respectively. Internal carotid artery (ICA) protrusion and dehiscence was present in 30 and 5% of patients, respectively. Dehiscence rates from local bone invasion overlying the ICA and ON occurred in 17 and 4% of cases, respectively.
Conclusions Our study highlights and reviews the key variants that have potential to impact surgical complications and outcomes in a heterogeneous patient population. The proposed preoperative CT checklist for patients, undergoing transsphenoidal surgery, consistently identifies these higher risk anatomical variants.

Published: May 2019

AbstractThe objective of this study was to investigate the knowledge and clinical practices of Brazilian pediatric intensivists in relation to usage of the concept of driving pressure. Knowledge and practice patterns were assessed using a survey tool. The overall response rate was 22.8% (84 of 369); 69% of physicians responded that they had sufficient knowledge on the concept of driving pressure but only 56% correctly answered to specific knowledge questions about it. The majority of respondents (72.6%) claim to use this concept in their clinical practice although pediatric data are insufficient to routinely support the practice. This also suggests a good degree of knowledge translation from adult studies.

Published: May 2019

AbstractThis study compared the severity of depression, anxiety, somatization, anxiety sensitivity, sleep disturbances, and quality of life (QoL) among children with migraine, children with tension-type headache (TTH), and healthy children. A total of 37 children with migraine, 22 with TTH, and a healthy control group (n = 35) participated in this study. Children with migraine exhibited higher depression and somatization and lower QoL scores than those in the control group. General sleep disturbances, bedtime resistance, sleep onset delay, sleep duration, sleep anxiety, night wakings, sleep-disordered breathing, and daytime sleepiness scores were also higher in those in the migraine group than in the control group. Regression models indicated that the severity of headache and depression scores significantly affected the QoLs of children with headache disorder as a whole. Migraine is associated with depression, somatization, sleep disturbances, and poor QoL, whereas TTH is associated with only sleep disturbances in childhood. The impact of headache on the QoL occurs mainly through the headache-specific and psychiatric factors.
nEoS: neutron star equation of state from hadron physics alone
Authors: Lope Oter Eva , Windisch Andreas , Llanes-Estrada Felipe J , Alford Mark 
Published: May 2019

Abstract
We contribute a publicly available set of tables and code to provide equations of state (EoS) for matter at neutron star densities. Our EoS are constrained only by input from hadron physics and fundamental principles, without feedback from neutron star observations, and so without relying on general relativity (GR). They can therefore be used to test GR itself, as well as modified gravity theories, with neutron star observables, without logical circularity. We have adapted state of the art results from NN chiral potentials for the low-density limit, pQCD results for the asymptotically high-density EoS, and use monotony and causality as the only restrictions for intermediate densities, for the EoS sets to remain as model-independent as is feasible today.
Fight against background noise in stimulated emission depletion nanoscopy
Authors: Ma Ye , Ha Taekjip 
Published: May 2019

Abstract
STimulated emission depletion (STED) nanoscopy has been proposed to extend greatly our capability of using light to study a variety of biological problems with nanometer-scale resolution. However, in practice the unwanted background noise degrades the STED image quality and precludes quantitative analysis. Here, we discuss the underlying sources of the background noise in STED images, and review current approaches to alleviate this problem, such as time-gating, anti-Stokes excitation removal, and off-focus incomplete depletion suppression. Progress in correcting uncorrelated background photons in fluorescence correlation spectroscopy combined with STED (STED-FCS) will also be discussed.

Published: May 2019

Abstract
Nowadays, in the traditional door or object recognition system, people use GluonCV and Tensorflow to help teach machines millions of pictures, and then base on the information in the database collected from the pictures to do the door recognition. While in the new proposal, a new door recognition system based on a machine carrier called GITA is proposed. In the proposal, the recognition elements comprise motionless elements, including door boundary, handle/bar, and ratio of body width and door width, and loco-motor elements, which include people’s gesture, change of door depth and change of illumination. In order to prove it, several different tests based on seven doors of different types are done.

Published: May 2019

Abstract
With the development of autonomous driving technology, it is possible self-driving cleaning truck being driving and working automatically. However, a lot of field trials are timeconsuming and wasteful during the investigation of self-driving truck. In order to reduce lots of on-site and real vehicle tests, we construct a 3D virtual pilotless vehicle testing system for the cleaning truck based on virtual reality technology. 3DMax software is used to build virtual 3D scene static model and cleaning truck model. The established static models are imported into Unity3D to simulate different 3D scenes during cleaning truck self-driving. We designed a UI interface to build a virtual testing system of self-driving cleaning truck which is easy to realize human-computer interaction. we have achieved successfully the avoidance of obstacles and round-the-island driving. And we have successfully completed the identification of traffic lights and the pilotless driving test on crossroad virtual scene. In the virtual testing system, we can quickly experience the virtual testing scenes of the self-driving cleaning truck in various scenarios and get some kinematics information. The virtual testing system can partly replace the field tests and provide methods and theoretical guidance for field test, which can shorten the development cycle and save money, and is also unrestricted and repeatable. At the same time, the researching results provide new ideas and methods for the investigation of vehicle tests and pilotless driving.

Published: May 2019

Abstract
With the rapid increase of cars, the research of license plate recognition in intelligent traffic algorithm has attracted much attention. In this paper, pointing at the shortcomings of the existing recognition algorithm, we adopt a license plate recognition method based on BP neural network with a median filtering. The method consists of a median filtering algorithm for denoising and a BP neural network for training and testing. First the character library is processed by median filtering to remove the influence of noise. Then, utilizing the strong learning ability of BP, the character library is passed into the network for classification. Compared with the traditional algorithm, our method not only speeds up the recognition efficiency, but also obtains more robust results. Therefore, the proposed approach can provide a technical support for the practical application of license plate recognizing.

Published: May 2019

Abstract
Temporal action detection is an important research topic in computer vision, of which Temporal Action Proposal (TAP) generation is a key step for finding candidate action segments. Our paper provides an action proposal generation network for temporally untrimmed videos in which a new effective and efficient deep architecture named action keyframe connection network for temporal action proposal Generation. Firstly, a two-stream network is adopted to extract frame-level features which inclued appearance feature and optical flow feature. The temporal information helps the subsequent network to determine whether a frame is the beginning or the ending of the action. Secondly, a position discrimination network is designed to infer the probability of each frame being starting frame or ending frame. The network outputs a starting probability sequence and an ending probability sequence which indicates the start of the action and the end of the action respectively. Finally, our network generates a proposal by a specific threshold rule combining the points in the starting probability sequence and the ending probability sequence. We carry out experiments on ActivityNet dataset to compare our proposed method with the state-of-the-art methods. Experiment results show that our method achieves superior performance over other methods.
