Optimization of Mammary Tissue Displacement in Ultrasound Elastography
Authors: Slimi Taher , Mahjoubi Halima , Tamali Romaissa
Published: August 2019

The displacement of mammary tissues in static ultrasound elastography is often contaminated by the speckle noise deteriorating its quality. Several techniques have been developed in this context, in order to treat the noise present in images of breast tissue displacement, the progress of research work in noise processing is always questioned, especially that must be taken into account the trade-off between noise reduction and preservation of breast tissue texture. In this paper, a new strategy has been proposed to reduce speckle noise. The proposed method not only filters the image against noise, but also preserves the details and contours of the tissue texture. The approach developed is based on the coupling between the image reconstructions by filtered back projection (RPF) with an adaptive filter. The proposed model proposed has been validated on an in-vivo database comprising 20 images of the breast tissues displacement. Qualitative and quantitative improvements were noted. By comparing the proposed method with the wavelet technique, we show that it is more efficient in terms of calculating the standard deviation between the pixels (SD), it is better in terms of calculation of the Contrast / Noise ratio (CNR). And is much faster than the wavelet technique. The results of the proposed model are encouraging, and the chosen method is ready to be used in the improvement of images of mammary tissue displacements in ultrasound elastography.

Becoming an Agricultural Growth Corridor
Authors: Stein Serena , Kalina Marc
Published: August 2019

Agricultural growth corridors (AGCs) have begun proliferating across the actual and policy landscapes of southeastern Africa. Cast as an emerging megaproject strategy, AGCs combine the construction of large-scale logistics (i.e., roads, railways, ports) with attracting investment in commercial agribusiness and smallholder farming. While scholars have long attended to spatial development schemes in the Global South, literature on the rising AGCs of Africa’s eastern seaboard has only recently shifted from anticipatory to empirical studies as policy implementation reaches full force. The article reflects on a new crop of studies that confront the problem of tracing policy imaginaries to the people, places, practices, and ecologies shaped by AGC schemes. In contrast to scholarship that accepts corridors as given entities, we explore directions for research that interrogate the grounded yet provisional becoming of these megaprojects. At such sites, the return of high modernist development logics encapsulated by the corridor concept may be questioned.

Pig production is the most important animal production sector in the EU, and the tail biting is still one of the most important problems of welfare and health. This behavioral disorder causes large economic losses through the medical costs for injured animals, prolonged rearing time, mortality, discarding of carcasses (or parts of carcasses) due to abscesses and finally due to potential transfer of other diseases. Abscesses, which develops because of tail biting besides economic risk, can also present a public health risk for consumers. In order to reduce potential risks, pig breeders still routinely dock tails (although forbidden by legislation), but this operation does not solve the problem but only reduce the symptoms. Although the European Union (EU) owns one of the most stringent regulatory frameworks on animal welfare in the world, due to the economic importance of pig production, the docking of tails is one issue on which the EU is turning its head. This is best illustrated by the fact that the largest pig producers Member States in the EU also have the highest percentage of routinely docked tails. Therefore, in the future, the common EU policies will need more concrete measures and activities to protect pig welfare and health. Significant role in that implementation of welfare assessment on farms and slaughterhouses shall certainly belong to the veterinary inspection, which will need to be systematically upgraded for this new role.

Researching sexuality and drug addiction
Authors: Di Francesco Gabrilele
Published: August 2019

The paper presents the methodological and technical aspects of a research project that set out to explore the relationship between sexuality and drugs addiction, with the twofold aim of a better focusing of the phenomenon which is hidden and difficult to read and at preparing appropriate strategies for the prevention of sexually transmitted diseases. The survey was carried out in the border area between the Italian regions Marche and Abruzzo, which is identified as the “pole of sex” [Ricci S., 1998:23] and where there are high rates of drug addiction. The survey involved the population of prostitutes, transvestites and transsexual who regularly attend the road called “Bonifica del Tronto”, between the provinces of Ascoli Piceno and Teramo and who are regular users of drugs (heroin, cocaine and others). It is a marginal population with various ethnic backgrounds, coming from Eastern Europe, Africa and Latin America, which now has a quite stable settlement in this area and is perceived almost as a “subculture of sex”. The majority of the subjects recruited for the research are users of the local Services for drugs addiction. This made the initial contact and recruitment less difficult as it was done through the mediation of the Service operators. The research adopted a qualitative methodological approach and has been carried out through individual interviews – mostly in the headquarters of the Services.

Chau Doc is a city of An Giang province in Mekong delta of Vietnam. This city has Sam Mountain with cultural and spiritual values. One of the highlights of the local spiritual culture is Ba Chua Xu (Lady Territory) shrine. Every year, this spot attracts between 3 and 5 million visitors. With a great number of tourists, the practicing of spiritual tourism has had an impact on the natural and cultural-social environment. The influence of stakeholders on the environment (nature and humanity) through the enjoyment and provision of tourism services. Stakeholders have involved in tourism activities in Chau Doc include: local authorities, service providers (food and beverage, accommodation, transportation, ...) and tourists. The practice of spiritual tourism is different from other types of tourism. Spiritual need has overwhelmed need to enjoy tourist services. With the expectation of improving economic benefits for the locality, tourism services are increasingly invested and supplemented. When economic interests are concerned, the issues of preserving natural values and cultural-social are limited, creating threat that could hurt the environment in Chau Doc. Therefore, the exploitation and development of spiritual tourism creates certain influence on the local environment. The study of the effects of spiritual tourism practice is necessary in the present context. Through field surveys, in-depth interviews with stakeholders and observations in local spiritual culture festivals from September 2016 to June 2018, this article describes and analyzes characteristics of practicing spiritual tourism in Chau Doc.

Attitudes Towards Places Associated With Communism: The Role of Place Attachment and Interest in Place History
Authors: Prusik Monika , Oleksy Tomasz , Wnuk Anna , Kula Agnieszka Maria
Published: August 2019

The aim of the study was to identify attitudes towards places commonly associated with the communist period of the Polish People’s Republic (PPR), and to investigate the role of the relationship between these attitudes and place attachment, interest in a city’s history and political orientation. This online study used a convenience sample of residents of the cities of Warsaw, Toruń and Poznań, N = 199. The exploratory factor analysis revealed that attitudes towards PPR places fall into two groups: those for the preservation of PPR places, and those for their removal. Moreover, this distinction was associated with, on the one hand, the preservation of ideologically free places (IFPs) such as cafes, milky bars, cinemas, and places that serve cultural functions. On the other, it was associated with the removal of ideologically contaminated places (ICPs) such as, e.g., monuments or street names reminiscent of awkward historical and political events. The inclination to remove ICPs was not related to place attachment but was positively related to interest in a city’s history; willingness to preserve IFPs, on the other hand, was correlated with higher traditional and active place attachment and with higher interest in a city’s history. Interest in a city’s history played a significant mediating role in this relationship. On a more general level, right-wing preferences coincided with being in favor of removing ICPs. Overall, the study adds to the literature by showing how place attachment is related to attitudes towards controversial historic places.

Published: August 2019

The results of the comparative analysis of the condition of immune system of medical workers living and working in different climatic and social conditions in Arkhangelsk and in Revda (Murmansk region) are presented. We have analyzed the results of immunological examination of 107 people working in medical institutions of Arkhangelsk and Revda. We studied the concentration of leukocytes, neutrophils, eosinophils, monocytes, lymphocytes, phagocytic index, the phenotypes of T- and B-lymphocytes, cytokines, CEA, immunoglobulins. Doctor's work is associated with activization of the cell-bound and the antibody-producing immune reactions with increase in blood of natural killers and cytotoxic lymphocytes with phenotype CD8+, and also IgA and IgE. This reaction is less expressed among working people in the Polar region and it seems it may be explained by some of inhibiting factors. It is lymphopenia, deficit of mature T- cells with phenotype CD3+, low concentration of IL-6 and CEA, higher level concentration of IL-10. The features of immune background of health workers from Revda can be caused by climate -ecological living conditions.

The aim of the study was to assess survival of patients with isolated and combined disorders of circulatory system and diabetes mellitus in Turkestan region, Southern Kazakhstan. Altogether, 1 143 randomly selected individuals comprised a cohort, which was followed up from 2003 through 2015. Data on diagnosis, age, gender, body mass index, smoking and alcohol consumption were collected by trained medical interviewers. Bivariate comparisons of survival between groups with no cardiovascular diseases and groups with isolated and combined disorders were performed using Kaplan-Meier analysis. Independent associations between the studied factors and overall mortality as well as mortality from cardiovascular causes were assessed using Cox regression. Crude and adjusted hazard ratios (HR) were calculated with 95 % confidence intervals (CI). The overall mortality in the cohort was 145 per 1 000 with cardiovascular causes accounting for 49 % of deaths during the study period. The risk of death from any cause was increased for individuals who had arterial hypertension and diabetes mellitus (HR = 4.6, 95 % CI: 1.4-15.3) and combined arterial hypertension, cardiac ischemia and diabetes mellitus (HR = 7.0, 95 % CI: 2.1-26.1) in fully adjusted Cox regression model. The risk of cardiovascular death was increased among patients with isolated cardiac ischemia (HR = 2.7, 95 % CI: 1.1-6.8) and among those with combined arterial hypertension and diabetes mellitus (HR = 8.7, 95 % CI: 2.5-30.4) adjusted for gender, age, smoke, alcohol consumption and body mass index. Combined disorders of circulatory system and diabetes mellitus considerably increase the risk of death in Turkestan region, Southern Kazakhstan warranting urgent need for evidence-based treatment of comorbidities and development of preventive programs.

Turfgrass mowing is one of the most important operations concerning turfgrass maintenance. Over time, different mowing machines have been developed, such as reel mowers, rotary mowers, and flail mowers. Rotary mowers have become the most widespread mowers for their great versatility and easy maintenance. Modern rotary mowers can be equipped with battery-powered electric motors and precise settings, such as blade rpm. The aim of this trial was to evaluate the differences in power consumption of a gasoline-powered rotary mower and a battery-powered rotary mower. Each mower worked on two different turfgrass species (bermudagrass and tall fescue) fertilized with two different nitrogen rates (100 and 200 kg ha−1). The battery-powered mower was set at its lowest and highest blade rpm value, while the gasoline-powered mower was set at full throttle. From the data acquired, it was possible to see that the gasoline-powered mower had a much higher primary energy requirement, independent of the turf species. Moreover, comparing the electricity consumption of the battery-powered mower over time, it was possible to see that the power consumption varied according to the growth rate of both turf species. These results show that there is a partial waste of energy when using a gasoline-powered mower compared to a battery-powered mower.

Authors: Attia Youssef A. , El-Naggar Asmaa Sh. , Abou-Shehema Bahaa M. , Abdella Ahmed A.
Published: August 2019

In this study, we investigated the influence of betaine (Bet, 1000 mg/kg), with or without vitamin C (VC, 200 mg/kg ascorbic acid) and/or vitamin E (VE, 150 mg/kg α-tocopherol acetate) on semen quality, seminal and blood plasma constituents, antioxidants’ status, DNA repair, and the welfare of chronic heat stress (CHS)-exposed roosters. A total of 54 roosters were divided into six groups of nine replicates. One group was kept under thermoneutral conditions, whereas the other five were kept under CHS. One of the five groups served as an unsupplemented CHS group, and was fed with a basal diet. The other four CHS groups were supplemented with Bet, Bet + VC, Bet + VE, and Bet + VC + VE, respectively. Our data indicate that supplementation with Bet, Bet + VC, Bet + VE, and Bet + VC + VE, resulted in complete recovery of the CHS effect on sperm concentration and livability, semen pH, and fertility compared to the thermoneutral group. Seminal plasma total antioxidant capacity (TAC) was significantly (p < 0.05) increased with Bet, with or without vitamins, compared to the thermoneutral and CHS groups. Urea and blood plasma malondialdehyde (MDA) were totally recovered with Bet, with or without vitamin treatments. Both the jejunum and ileum DNA were partially recovered following Bet, with or without vitamin supplementation. In conclusion, Bet, at 1000 mg/kg feed, may be a useful agent for increasing semen quality, fertility, welfare, and to improve the breeding strategy of breeder males in hot climates.
Preparation of Multicycle GO/TiO2 Composite Photocatalyst and Study on Degradation of Methylene Blue Synthetic Wastewater
Authors: Fu Zhongtian , Zhang Song , Fu Zhongxue
Published: August 2019

A series of composite photocatalysts were prepared by using graphene oxide (GO) prepared by modified Hummers method and TiO2 hydrogel prepared by using butyl titanate as raw materials. The composite photocatalyst was characterized through scanning electron microscope（SEM）, x ray diffraction （XRD）, and Raman spectroscopy, and the degradation effect of pure TiO2 and composite photocatalyst on methylene blue (MB) dye wastewater under different experimental conditions was studied. The results showed that TiO2 in composite photocatalyst was mainly anatase phase and its photocatalytic activity was better than pure TiO2. When the addition of GO reached 15 wt%, the photocatalytic activity was the highest. When 200 mg composite photocatalyst was added to 200 mL synthetic wastewater with a concentration of 10 mg/L and an initial pH of about 8, the degradation rate could reach 95.8% after 2.5 h. It is presumed that the photogenerated charges of GO/TiO2 composite photocatalyst may directly destroy the luminescent groups in the MB molecule and thus decolorize the wastewater, and no other new luminescent groups are generated during the treatment.
Semantic-Based Representation Binary Clone Detection for Cross-Architectures in the Internet of Things
Authors: Luo Zhenhao , Wang Baosheng , Tang Yong , Xie Wei
Published: August 2019

Code reuse is widespread in software development as well as internet of things (IoT) devices. However, code reuse introduces many problems, e.g., software plagiarism and known vulnerabilities. Solving these problems requires extensive manual reverse analysis. Fortunately, binary clone detection can help analysts mitigate manual work by matching reusable code and known parts. However, many binary clone detection methods are not robust to various compiler optimization options and different architectures. While some clone detection methods can be applied across different architectures, they rely on manual features based on human prior knowledge to generate feature vectors for assembly functions and fail to consider the internal associations between features from a semantic perspective. To address this problem, we propose and implement a prototype GeneDiff, a semantic-based representation binary clone detection approach for cross-architectures. GeneDiff utilizes a representation model based on natural language processing (NLP) to generate high-dimensional numeric vectors for each function based on the Valgrind intermediate representation (VEX) representation. This is the first work that translates assembly instructions into an intermediate representation and uses a semantic representation model to implement clone detection for cross-architectures. GeneDiff is robust to various compiler optimization options and different architectures. Compared to approaches using symbolic execution, GeneDiff is significantly more efficient and accurate. The area under the curve (AUC) of the receiver operating characteristic (ROC) of GeneDiff reaches 92.35%, which is considerably higher than the approaches that use symbolic execution. Extensive experiments indicate that GeneDiff can detect similarity with high accuracy even when the code has been compiled with different optimization options and targeted to different architectures. We also use real-world IoT firmware across different architectures as targets, therein proving the practicality of GeneDiff in being able to detect known vulnerabilities.

Published: August 2019

In this study, Zernike polynomials and optical fiber field theory are applied to build a mathematical model of coupling efficiency (CE) and spatial mode of aberrations. The theory built in this paper can be used to quickly calculate the CE affected by a single aberration as well as the aberrations caused by atmospheric turbulence. The aberrations are classified based on Zernike polynomials and the effects of aberrations on CE of different types and different spatial frequencies are analyzed. The influence of the effects of AO system residual errors is also analyzed. Adaptive optics (AO) equipment is applied to build a system on which the proposed theory was tested; the experimental results validate the theoretical analysis.

Composed of metallic or dielectric structures whose shape and position are carefully engineered on the metal surface, traditional SPP devices are generally static and lack tunability. Dynamical manipulation of SPP is meaningful in both fundamental research and practical applications. In this article, the achievements in dynamical SPP excitation, SPP focusing, SPP vortex, and SPP nondiffracting beams are presented. The mechanisms of dynamical SPP devices are revealed and compared, and future perspectives are discussed.

Thermal comfort and sensation are important aspects of building design and indoor climate control, as modern man spends most of the day indoors. Conventional indoor climate design and control approaches are based on static thermal comfort/sensation models that view the building occupants as passive recipients of their thermal environment. To overcome the disadvantages of static models, adaptive thermal comfort models aim to provide opportunity for personalized climate control and thermal comfort enhancement. Recent advances in wearable technologies contributed to new possibilities in controlling and monitoring health conditions and human wellbeing in daily life. The generated streaming data generated from wearable sensors are providing a unique opportunity to develop a real-time monitor of an individual’s thermal state. The main goal of this work is to introduce a personalized adaptive model to predict individual’s thermal sensation based on non-intrusive and easily measured variables, which could be obtained from already available wearable sensors. In this paper, a personalized classification model for individual thermal sensation with a reduced-dimension input-space, including 12 features extracted from easily measured variables, which are obtained from wearable sensors, was developed using least-squares support vector machine algorithm. The developed classification model predicted the individual’s thermal sensation with an overall average accuracy of 86%. Additionally, we introduced the main framework of streaming algorithm for personalized classification model to predict an individual’s thermal sensation based on streaming data obtained from wearable sensors.

Natural ventilation is the most common passive cooling system in livestock buildings. The aim of this research is to assess airflow distribution inside a free-stall barn for dairy cows by computational fluid dynamics (CFD) modelling and simulation. The model is validated by using the average values of experimental data acquired in a free-stall barn, which is considered relevant because it is located in a region characterised by hot climate conditions during the summer that could induce animal heat stress. Simulations are carried out in steady-state conditions, and simulated data are validated by the average values of air velocity measurements. Since the modelled air velocity distribution in the barn fits the real one well, the CFD model is considered reliable to simulate other conditions. The application of the proposed CFD model in the simulation of specific building design alternatives could be aimed at studying the related airflow distribution in order to find the best configuration.

The band gap controlled photocatalyst (Zn0.74Cu0.13In2S3.805) was prepared via a simple one-step solvothermal method. The effects of doping of Cu+ and excess In on the photocatalytic activity of ZnIn2S4 photocatalyst were investigated. In addition, optical properties, surface morphology and crystal structure were evaluated. The maximum H2 evolution rate (2370 µmol h−1 g−1) was achieved with Zn0.74Cu0.13In2S3.805, which was about five times higher than that of untreated ZnIn2S4 under visible light (λ ≥ 420 nm). The band gap of Zn0.74Cu0.13In2S3.805 decreased to 1.98 eV by raising the maximum position of the valence band, compared to ZnIn2S4. Furthermore, the recombination of electron hole pairs was effectively reduced. This research contributes to the development of highly active photocatalysts under visible light.

Neuroglobin is a heme protein of which increased levels provide neuroprotection against amyloid proteinopathy and hemorrhagic damage. These cellular stressors involve the promotion of ferroptosis—an iron-dependent, lipid peroxide-accreting form of cell death. Hence, we questioned whether neuroglobin could oppose ferroptosis initiation. We detected human neuroglobin (hNgb)-EGFP-expressing SH-SY5Y cells to be significantly more resistant to ferroptosis induction, identifying 0.68-fold less cell death. To elucidate the underlying pathways, this study investigated hNgb-protein interactions with a Co-IP-MS/MS approach both under a physiological and a ferroptotic condition. hNgb binds to proteins of the cellular iron metabolism (e.g., RPL15 and PCBP3) in an unstressed condition and shows an elevated binding ratio towards cell death-linked proteins, such as HNRNPA3, FAM120A, and ABRAXAS2, under ferroptotic stress. Our data also reveal a constitutive interaction between hNgb and the longevity-associated heterodimer XRCC5/XRCC6. Disentangling the involvement of hNgb and its binding partners in cellular processes, using Ingenuity Pathway Analysis, resulted in the integration of hNgb in the ubiquitination pathway, mTOR signaling, 14-3-3-mediated signaling, and the glycolysis cascade. We also detected a previously unknown strong link with motor neuropathies. Hence, this study contributes to the elucidation of neuroglobin’s involvement in cellular mechanisms that provide neuroprotection and the upkeep of homeostasis.

The corrosion protection of coatings can be reinforced by the addition of entrapped corrosion inhibitors. β-cyclodextrin (β-CD) can form inclusion complexes with small inhibiting organic molecules that, when entrapped in coatings, allow the inhibitor release and adsorption at corrosion initiation sites. In this paper, several Nuclear Magnetic Resonance (NMR)-based experiments (e.g., Complexation-Induced Shifts (CIS), NMR titration, Diffusion-Ordered Spectroscopy (DOSY)) were performed to study the stability and geometry of a complex formed by β-cyclodextrin with 5-mercapto-1-phenyl-tetrazole (MPT). The complex was also detected by Electrospray Ionization (ESI) mass spectrometry and characterized by Fourier Transform Infrared (FTIR) spectra. Its influence on the protectiveness of a silane coating against bronze corrosion was evaluated in plain (AR) and concentrated (ARX10) synthetic acid rain, under different exposure conditions. In particular, the time evolution of the polarization resistance values during 20 days in ARX10 and the polarization curves recorded at the end of the immersions evidenced a higher protectiveness of the coating with the β-CD–MPT complex in comparison to that containing only MPT or only β-CD. The cyclic AR spray test carried out on coated bronze coupons with cross-cut scratches evidenced the absence of underfilm corrosion starting from the scratches only in the complex-containing coating.

A growing interest appears among public authorities and society in accurate and nearly real time aftershock forecasting to manage and mitigate post-seismic risk. Existing methods for aftershock forecasting are strongly affected by the incompleteness of the instrumental datasets available soon after the main shock occurrence. The deficit of observed events, in the first part of aftershock sequences, can be naturally attributed to various mechanisms such as the inefficiency of the seismic network and the overlap of earthquake signals in seismic records. In this review, we show that short-term aftershock incompleteness can be explained only in terms of the second mechanism, whereas it is only weakly affected by the quality of the instrumental coverage. We then illustrate how standard models for earthquake forecasting can be modified to take into account this incompleteness. In particular, we focus on forecasting methods based on the data available in real time, in which many events are missing and the uncertainty in hypocenter location is considerable. We present retrospective tests that demonstrate the usefulness of these novel methods compared with traditional ones, which implement average values of parameters obtained from previous sequences.
Smart Approaches to Food Waste Final Disposal

Published: August 2019

Food waste, among the organic wastes, is one of the most promising substrates to be used as a renewable resource. Wide availability of food waste and the high greenhouse gas impacts derived from its inappropriate disposal, boost research through food waste valorization. Several innovative technologies are applied nowadays, mainly focused on bioenergy and bioresource recovery, within a circular economy approach. Nevertheless, food waste treatment should be evaluated in terms of sustainability and considering the availability of an optimized separate collection and a suitable treatment facility. Anaerobic codigestion of waste-activated sludge with food waste is a way to fully utilize available anaerobic digestion plants, increasing biogas production, energy, and nutrient recovery and reducing greenhouse gas (GHG) emissions. Codigestion implementation in Europe is explored and discussed in this paper, taking into account different food waste collection approaches in relation to anaerobic digestion treatment and confirming the sustainability of the anaerobic process based on case studies. Household food waste disposal implementation is also analyzed, and the results show that such a waste management system is able to reduce GHG emissions due to transport reduction and increase wastewater treatment performance.
