Correlations of High-pT Hadrons and Jets in ALICE
Authors: Krizek Filip
Published: May 2019

There are two prominent experimental signatures of quark–gluon plasma creation in ultra-relativistic heavy-ion collisions: the jet quenching phenomenon and the azimuthal-momentum space-anisotropy of final-state particle emission. Recently, the latter signature was also observed in lighter collision systems such as p–Pb or pp. This raises a natural question of whether in these systems, the observed collectivity is also accompanied by jet quenching. In this paper, we overview ALICE measurements of the jet quenching phenomenon studied using semi-inclusive distributions of track-based jets recoiling from a high-transverse momentum ( p T ) hadron trigger in Pb–Pb and p–Pb collisions at LHC energies. The constructed coincidence observable, the per trigger normalized yield of associated recoil jets, is corrected for the complex uncorrelated jet background, including multi-partonic interactions, using a data-driven statistical subtraction method. In the p–Pb data, the observable was measured in events with different underlying event activity and was utilized to set an upper limit on the average medium-induced out-of-cone energy transport for jets with resolution parameter R = 0.4 . The associated jet momentum shift was found to be less than 0.4 GeV/c at 90% confidence.
Human Ecology and Its Influence in Urban Theory and Housing Policy in the United States
Authors: García Ivis
Published: May 2019

Human ecology, a stream of planning, was developed by Park, Burgess, and Hoyt. This theoretical model emphasized mobility and assimilation as natural paths to housing. This essay offers an analysis of its influence on urban theory and policymaking in the United States. Using planning-specific analyses, the author interrogates the relationships between structural and ecological interpretations of urban change within early planning theory. A particular focus is given to housing policies and models such as tipping point, segregation, and gentrification. These human ecological interpretations inspired and shaped urban renewal and redlining practices, along with public and affordable housing in the United States. The essay concludes with a criticism of the ecological ideas of spontaneous order and the claims of naturally balancing economic systems and conceptions of personal responsibility and choice.
Don’t Shut the Stable Door after the Phage Has Bolted—The Importance of Bacteriophage Inactivation in Food Environments

Published: May 2019

In recent years, a new potential measure against foodborne pathogenic bacteria was rediscovered—bacteriophages. However, despite all their advantages, in connection to their widespread application in the food industry, negative consequences such as an uncontrolled phage spread as well as a development of phage resistant bacteria can occur. These problems are mostly a result of long-term persistence of phages in the food production environment. As this topic has been neglected so far, this article reviews the current knowledge regarding the effectiveness of disinfectant strategies for phage inactivation and removal. For this purpose, the main commercial phage products, as well as their application fields are first discussed in terms of applicable inactivation strategies and legal regulations. Secondly, an overview of the effectiveness of disinfectants for bacteriophage inactivation in general and commercial phages in particular is given. Finally, this review outlines a possible strategy for users of commercial phage products in order to improve the effectiveness of phage inactivation and removal after application.
A River Temperature Model to Assist Managers in Identifying Thermal Pollution Causes and Solutions
Authors: Abdi Reza , Endreny Theodore
Published: May 2019

Thermal pollution of rivers degrades water quality and ecosystem health, and cities can protect rivers by decreasing warmer impervious surface stormwater inflows and increasing cooler subsurface inflows and shading from riparian vegetation. This study develops the mechanistic i-Tree Cool River Model and tests if it can be used to identify likely causes and mitigation of thermal pollution. The model represents the impacts of external loads including solar radiation in the absence of riparian shade, multiple lateral storm sewer inflows, tributaries draining reservoirs, groundwater flow, and hyporheic exchange flow in dry weather steady flows and wet weather unsteady flows. The i-Tree Cool River Model estimates the shading effects of the riparian vegetation and other features as a function of heights and distances as well as solar geometry. The model was tested along 1500 m of a New York mountain river with a riparian forest and urban areas during 30 h with two summer storm events in 2007. The simulations were sensitive to the inflows of storm sewers, subsurface inflows, as well as riparian shading, and upstream boundary temperature inflows for steady and unsteady conditions. The model simulated hourly river temperature with an R2 of 0.98; when shading was removed from the simulation the R2 decreased 0.88, indicating the importance of riparian shading in river thermal modeling. When stormwater inflows were removed from the simulation, the R2 decreased from 0.98 to 0.92, and when subsurface inflows were removed, the R2 decreased to 0.94. The simulation of thermal loading is important to manage against pollution of rivers.

Advanced Driver Assistance System (ADAS) and Automated Driving (AD) are the two major topics for the current and next generations of vehicles. To realize them in full-size vehicles equipped with a 12 V power supply, the need for electric power steering (EPS) is increasing. Currently, the steering system of full-size vehicles is equipped with hydraulic power steering due to electric power shortage. An auxiliary power supply system using a lithium-ion capacitor was developed in order to solve the concern. In addition, to mount the system in the vehicle with no cooling–heating equipment, development of expanding the operating temperature range of the lithium-ion capacitor was conducted. Several improvements have made the capacitor operate stably in high-temperature environments above 100 °C.

Authors: Шорстов Роман , Shorstov Roman
Published: May 2019

The article discusses the possibility of regulation by changing the amount of aluminum paste, the temperature of the mixing water and the sides of mold for the expansion of molding sand of autoclaved aerated concrete. Also, the achievement of a given maximum temperature of the array, which determines the nature of the pore structure and physico-mechanical properties of products. Mathematical models for optimizing the physicomechanical properties of autoclaved aerated concrete by regulating technological and prescription parameters are obtained using the method of mathematical planning of an experiment. It is established, optimal parameters are the mixing water temperature of 40 ... 45 ° C, the amount of aluminum paste - 0.6% of the binder mass, the temperature of the sides of the form 85 ... 90 ° C, which creates favorable conditions for the expansion of the gas-concrete mixture and the combination of pore formation and set-up structural strength of the array, allowing to obtain an optimal porous structure with smaller and uniform porosity with a sufficiently low density and high strength

Published: May 2019

The information about the composition of the anti-icing coating is provided. The use of acrylic resin A-01 and DEGALAN®, highly chlorinated polyethylene resin HCPE and silicone resin SILRES® MSE 100 as a binder is considered. The regularities of changes in viscosity of the composition depending on volume content of the filler – Aerosil brand R 972 are revealed. It is found that the viscosity increase is insignificant when filling in the range 0<φ<0.012. With further filling (φ>0,012) there is a significant change in the ratio of the volume and membranous phases of the matrix, there is a sharp increase in the viscosity of the composition. The optimal volumetric composition of the filler is established for each type of the resin. It is revealed that the interaction in the filler-filler system prevails over the interaction in the filler-binder system. In assessing the hydrophobic properties, it is found that the coatings have a high contact angle (more than 150°), and the roll-off angle does not exceed 10°, which confirms the presence of superhydrophobicity and assumes anti-icing properties of the coatings. The adhesion of the coating to the substrate estimated by the lattice incision method on the mortar and metal substrates is 1 point. Smooth and clear cuts without chipping and cracking are marked at 4x magnification

Published: May 2019

The necessity of establishing and determining the consistency of mortars deformation in the horizontal joints of masonry is established: in the absence and development of cracks and with the exhaustion of resistance ranging from 80 – 85 % of the total deformation of masonry under short-term compression. Attention is paid to the absence of reports in the scientific literature on the conduct and results of research on the spatial stress-deformative state of the mortar in the joints of masonry under compression. The advantages of studying the secant modulus of deformation Ep are emphasized in solving various issues in the theory of operation and method for calculating the masonry. On the basis of long-term research results, the essential difference between the change in the secant modulus of cement mortars deformation E'p of varying strength of horizontal joints from the nature of its change when tested in standard samples is shown analytically and graphically. The advantages of the developed methodology for processing the results of investigations of mortars in standard samples are noted. It allows to more accurately set the actual values of normal strain modulus E0 and the ultimate relative deformation under compression. The analytical dependences of the plasticity coefficient and the secant modulus of deformations E'p are found based on processing the results of numerous studies of masonry mortars

Analog modelling in qualitative analysis of vibration propagation
Authors: Mieloszyk Eligiusz , Grulkowski Sławomir
Published: May 2019

The theory of dynamic systems is usually used to model the real systems. The models are based on solving ordinary differential equations, partial or difference, which enable obtaining the relation between input signal and the system response (output signal). The analogy between those models and generalized dynamic systems or control systems can be practically used. Vibration propagation can be described in a similar way as the phenomena of vibrations of the electrical, mechanical, or hydraulic systems, diffusion, heat propagation, wave propagation or advection. The physical problem will be solved based on generalized dynamic systems, which enables drawing corresponding conclusions. This concept will be applied to qualitative analysis of vibration propagation in the foundations of transportation constructions”.

Hazards in the Polish Civil Aviation resulting from engines failures
Authors: Głowacki Paweł , Loroch Leszek
Published: May 2019

Published by the Civil Aviation Authority in May 2017, the State Safety Programme 2017-2020 in the appendix A presents "Events Data - 2016". Detailed description of the hazard arising from the technical condition of aircraft limits to the general presentation of the events in terms of SCF-NP (System Component Failure Non Powerplant) and SCF-PP (System Component Failure Powerplant). The analysis of these events performed in the Institute of Aviation (aviation events reports are collected in the European Coordination Center for Accident and Incident Reporting System database - ECCAIRS) has shown that the general aviation and commercial aviation (CAT) should be treated separately. Especially events caused by the powerplants failures must be considered separately for piston, turbofan, turboshaft, turboprop types and also their each installation has to be taken into account. Events caused by the technical condition of aircraft, especially engines, are the most common cause of accidents in general aviation. The aim of the article is to improve risk awareness and, ultimately, reduce the number of the aviation events associated with exploitation of the piston engines. Particularly significant impact on reducing the number of accidents in general aviation can be achieved by the implementation of modern technical solutions to control the technical condition of the engines and reduce their operating costs, while operators are fully aware of the risks resulting from the possibility of extending engine time on wing. In conclusion: reversing the dangerous trend of piston engine failures causing aviation safety hazards requires, above all, changes in the way these engines are operated.

Published: May 2019

Why some people do not volunteer? After doing a comprehensive literature review we
summarized all potential reasons that have been mentioned so far. However, we
also found important discrepancies between different studies. Thus, we
concluded that an exploratory research can be useful to understand why people
do not volunteer. In this study, by conducting nine focus groups we analyzed
why university students from various disciplines of social sciences do not
volunteer in Turkey. Focus groups were realized with 52 university students in
Istanbul. Results revealed that the primary reason for the reluctance of
university students to volunteer was related to trust issues. In other words,
in Turkey, university students do not volunteer as they do not trust NGOs. Some
other important reasons were also discussed in the article.

Use of a single reference genome for genome‐wide association studies (GWAS) limits the gene space represented to that of a single accession. This limitation can complicate identification and characterization of genes located within presence–absence variations (PAVs). In this study, we present the draft de novo genome assembly of ‘PHJ89’, an ‘Oh43’‐type inbred line of maize (Zea mays L.). From three separate reference genome assemblies (‘B73’, ‘PH207’, and PHJ89) that represent the predominant germplasm groups of maize, we generated three separate whole‐seedling gene expression profiles and single nucleotide polymorphism (SNP) matrices from a panel of 942 diverse inbred lines. We identified 34,447 (B73), 39,672 (PH207), and 37,436 (PHJ89) transcripts that are not present in the respective reference genome assemblies. Genome‐wide association studies were conducted in the 942 inbred panel with both the SNP and expression data values to map Sugarcane mosaic virus (SCMV) resistance. Highlighting the impact of alternative reference genomes in gene discovery, the GWAS results for SCMV resistance with expression values as a surrogate measure of PAV resulted in robust detection of the physical location of a known resistance gene when the B73 reference that contains the gene was used, but not the PH207 reference. This study provides the valuable resource of the Oh43‐type PHJ89 genome assembly as well as SNP and expression data for 942 individuals generated from three different reference genomes.
A FRAMEWORK FOR THE TAXONOMY AND ASSESSMENT OF NEW AND EMERGING TRANSPORT TECHNOLOGIES AND TRENDS
Authors: Gkoumas Konstantinos , Tsakalidis Anastasios
Published: May 2019

This paper focuses on the development of a taxonomy framework for new and emerging technologies and trends in the transport sector. This framework is proposed towards the assessment and monitoring of the acceptance, impact and diffusion of technologies and trends, together with a scoring system and a front–end visualisation of the outcomes. In this context, an overview of the transport technology hype over the last years and the establishment of future transport technologies and trends is provided. Issues arising from different constraints, including technological and technical, are taken into account, also considering the transport sector’s interconnection with other sectors and potentially related bottlenecks and drawbacks. The paper outcome is a methodological framework for the creation of different taxonomies for new and emerging transport technologies and trends, achieved through the quantitative assessment of the attractiveness and competitiveness, in terms of diffusion potential, of emerging transport technologies and trends, by associating explicit indices to the various elements of the taxonomies. The proposed taxonomy, assessment and monitoring framework supports innovation management through the identification and evaluation of new and emerging technologies and trends in the field of transport at various levels, thus providing insights to the sector’s stakeholders, while backing the current transport systems’ transformation through technological advances

We use reconstructed star formation (SF) histories of quiescent galaxies at z = 0.6–1 in the Large Early Galaxy Astrophysics Census survey to identify secondary SF episodes that, after an initial period of quiescence, moved the galaxies back to the star-forming main sequence (blue cloud). 16 ± 3% of the z ∼ 0.8 quiescent population has experienced such rejuvenation events in the redshift range of 0.7 < z < 1.5 after reaching quiescence at some earlier time. On average, these galaxies first became quiescent at z = 1.2, and those that rejuvenated, remained quiescent for ∼1 Gyr before their secondary SF episode, which lasted ∼0.7 Gyr. The stellar mass attributed to rejuvenation is on average 10% of the galaxy stellar mass, with rare instances of an increase of more than a factor of 2. Overall, rejuvenation events only contribute ∼2% of the total stellar mass in z ∼ 0.8 quiescent galaxies and we conclude that rejuvenation is not an important evolutionary channel when considering the growth of the red sequence. However, our results complicate the interpretation of galaxy demographics in color space: the galaxies with rejuvenation events tend to lie in the so-called “green valley,” yet their progenitors were quiescent at z ∼ 2.
The Interplay of Kinetic and Radiative Feedback in Galaxy Clusters
Authors: Qiu 邱 Yu 宇 , Bogdanović Tamara , Li Yuan , Park KwangHo , Wise John H.
Published: May 2019

Recent observations provide evidence that some cool-core clusters host quasars in their brightest cluster galaxies (BCGs). Motivated by these findings, we use 3D radiation-hydrodynamic simulations with the code Enzo to explore the joint role of kinetic and radiative feedback from supermassive black holes (SMBHs) in BCGs. We implement kinetic feedback as subrelativistic plasma outflows and model radiative feedback using ray-tracing radiative transfer or thermal energy injection. In our simulations, the central SMBH transitions between the radiatively efficient and radiatively inefficient states on timescales of a few gigayears, as a function of its accretion rate. The timescale for this transition depends primarily on the fraction of power allocated to each feedback mode, and to a lesser degree on the overall feedback luminosity of the active galactic nucleus (AGN). Specifically, we find that (a) kinetic feedback must be present at both low and high accretion rates in order to prevent the cooling catastrophe, and (b) its contribution likely accounts for >10% of the total AGN feedback power, because below this threshold simulated BCGs tend to host radio-loud quasars most of the time, in apparent contrast with observations. We also find a positive correlation between the AGN feedback power and the mass of the cold gas filaments in the cluster core, indicating that observations of Hα filaments can be used as a measure of AGN feedback.

Dwarf carbon (dC) stars (main-sequence stars showing carbon molecular bands) were initially thought to be an oxymoron because only asymptotic giant branch (AGB) stars dredge carbon into their atmospheres. Mass transfer from a former AGB companion that has since faded to a white dwarf seems the most likely explanation. Indeed, a few types of giants known to show anomalous abundances—notably, the CH, Ba and CEMP-s stars—are known to have a high binary frequency. The dC stars may be the enhanced-abundance progenitors of most, if not all of these systems, but this requires demonstrating a high binary frequency for dCs. Here, for a sample of 240 dC stars targeted for repeat spectroscopy by the SDSS-IV’s Time Domain Spectroscopic Survey, we analyze radial velocity (RV) variability to constrain the binary frequency and orbital properties. A handful of dC systems show large velocity variability (>100 km s−1). We compare the dCs to a control sample with a similar distribution of magnitude, color, proper motion, and parallax. Using Markov chain Monte Carlo methods, we use the measured ΔRV distribution to estimate the binary fraction and the separation distribution assuming both a unimodal and bimodal distribution. We find the dC stars have an enhanced binary fraction of 95%, consistent with them being products of mass transfer. These models result in mean separations of less than 1 au corresponding to periods on the order of 1 yr. Our results support the conclusion that dC stars form from close binary systems via mass transfer.

Angrite meteorites are some of the oldest materials in the solar system. They provide important information on the earliest evolution of the solar system and accretion timescales of protoplanets. Here, we show that the 54Cr/52Cr ratio is homogeneously distributed among angrite meteorites within 13 parts per million, indicating that precursor materials must have experienced a global-scale melting such as a magma ocean. The 53Cr/52Cr and Mn/Cr ratios are correlated, which is evidence for an initial 53Mn/55Mn ratio of (3.16 ± 0.11) × 10−6. When anchored to the U-corrected Pb–Pb age for the D’Orbigny angrite, this initial 53Mn/55Mn corresponds to an absolute age of 4563.2 ± 0.3 Ma, i.e., 4.1 ± 0.3 Ma after Ca–Al-rich inclusion-formation. This age is distinct from that of the volatile depletion events dated by the 87Sr/86Sr initial ratio and therefore must correspond to the age of crystallization of the magma ocean and crust formation of the angrite parent body (APB), which can also constrain a slightly bigger size of APB than that of Vesta. Furthermore, this age is similar to those obtained from internal isochrons of the oldest volcanic angrites that cooled rapidly at the surface of the parent body (with ages of 4564 ∼ 4563 Ma), while older than those obtained from plutonic angrites (4561 ∼ 4556 Ma) that cooled down slowly, located deeper within the parent body. This implies that cooling of the APB took at least ∼8 Myr after its differentiation.
L’amour du théâtre. Réflexions sur l’épisode de l’effondrement des gradins survenu en 1349 à Kyôto

Published: May 2019

L’article examine un événement datant des débuts du théâtre nô (l’effondrement des gradins provoqué par un démon déguisé en moine) pour montrer que le nô, théâtre avant tout dédié aux morts, assumait, auprès des autorités politiques, une fonction expiatoire. Par la suite, le théâtre de Zeami, dont la forme est plus élaborée, ne fit que confirmer cela, ce qui explique pourquoi le théâtre nô, loin de susciter le rejet, a toujours été apprécié et protégé par les autorités shôgunales.
Neurofeedback
Authors: Gupta Meena , Bhatia Dinesh
Published: May 2019

Neurofeedback (NF) is a type of brain wave training based on operant learning. NF has been employed in research and clinical settings for the investigation and treatment of a growing number of psychological illnesses. This technique involves detection of electroencephalographic (EEG) information from the surface of the scalp of a subject by separating its frequency decomposition into its component waveform (alpha, beta, theta, gamma, and delta) and making these components visible usually as polygraphic traces on a computer screen. Neurofeedback is being considered as a promising new method for restoring brain function in a large number of mental disorder cases. NF takes into account behavioral, cognitive, and subjective aspects as well as the brain activity of the concerned individual. About 25 years ago, NF was employed for clinical and research purposes in psychological illness. These psychological illnesses include attention deficit disorder, addiction to drug, depression, stress, and eating disorders.

Neurological disorders are some of the leading chronic disorders that impose a massive burden on low-income and developing countries. The disability resulting from the neurological disorder increases the severity and costs during the primary healthcare and for entire lifetime. Parkinson's disease (PD) is the second most common chronic neurodegenerative disorder which is slowly progressive with decrease in the motor and non-motor function of the nervous system due to cognitive impairment leading to gait abnormality. PD is most common in the age group of 40-65years leading to increase in gait disorders associated with slowing down of the movement, balance instability, rigidness in the muscles, and difficulty in performing everyday tasks. The assessment of gait plays a significant role in maintaining the balance disorders in Parkinson's disease. In patients with PD, the neurons present in substantia nigra region of the brain get injured, and they progressively decline during their lifetime. Therefore, the patients lose their ability to perform movement and also lose their stability. The symptoms of PD can be monitored and controlled by assessing gait parameters based on gait disorder.
Designing Thin 2.5D Parts Optimized for Fused Deposition Modeling

Published: May 2019

This chapter builds new knowledge for design engineers adopting fused deposition modeling (FDM) technology as an end manufacturing process, rather than simply as a prototyping process. Based on research into 2.5D printing and its use in real-world additive manufacturing situations, a study featuring 111 test pieces across the range of 0.4-4.0mm in thickness were analyzed in increments of 0.1mm to understand how these attributes affect the quality and print time of the parts and isolate specific dimensions which are optimized for the FDM process. The results revealed optimized zones where the outer wall, inner wall/s, and/or infill are produced as continuous extrusions significantly faster to print than thicknesses falling outside of optimized zones. As a result, a quick reference graph and several equations are presented based on fundamental FDM principles, allowing design engineers to implement optimized wall dimensions in computer-aided design (CAD) rather than leaving print optimization to technicians and manufacturers in the final process parameters.
The Evolution of the Role of Women in Labor Markets in Developed Economies
Authors: Pereira Elisabeth T. , Salaris Stefano
Published: May 2019

The role of women in labor markets has been characterized by great changes in the last century, with gender inequalities decreasing in most developed countries. The stereotypes related to women in labor markets have been hard to break within social norms and cultures. Many efforts have been made in recent decades by governments and national and international institutions to decrease and promote women's empowerment and gender equality in labor markets. This chapter has as its main purposes to provide an overview of the evolution of the role of women in labor markets in developed countries and to investigate this evolution based on a set of variables: gender participation rates, education, employment, the gender gap in management, wages and the gender wage gap, and public policies and laws. However, despite the positive evolution of the participation rate of women in labor markets that has been observed in recent decades, gender inequalities still persist.
