A benchmarking measurement campaign in GNSS-denied/challenged indoor/outdoor and transitional environments

Abstract Localization in GNSS-denied/challenged indoor/outdoor and transitional environments represents a challenging research problem. This paper reports about a sequence of extensive experiments, conducted at The Ohio State University (OSU) as part of the joint effort of the FIG/IAG WG on Multi-sensor Systems. Their overall aim is to assess the feasibility of achieving GNSS-like performance for ubiquitous positioning in terms of autonomous, global, preferably infrastructure-free positioning of portable platforms at affordable cost efficiency. In the data acquisition campaign, multiple sensor platforms, including vehicles, bicyclists and pedestrians were used whereby cooperative positioning (CP) is the major focus to achieve a joint navigation solution. The GPSVan of The Ohio State University was used as the main reference vehicle and for pedestrians, a specially designed helmet was developed. The employed/tested positioning techniques are based on using sensor data from GNSS, Ultra-wide Band (UWB), Wireless Fidelity (Wi-Fi), vison-based positioning with cameras and Light Detection and Ranging (LiDAR) as well as inertial sensors. The experimental and initial results include the preliminary data processing, UWB sensor calibration and Wi-Fi indoor positioning with room-level granularity and platform trajectory determination. The results demonstrate that CP techniques are extremely useful for positioning of platforms navigating in swarms or networks. A significant performance improvement in terms of positioning accuracy and reliability is achieved. Using UWB, decimeter-level positioning accuracy is achievable under typical conditions, such as normal walls, average complexity buildings, etc. Using Wi-Fi fingerprinting, success rates of approximately 97 % were obtained for correctly detecting the room-level location of the user.
A New Solution for Sea Wave Energy Harvesting, the Proposal of an Ironless Linear Generator

The paper investigates an innovative ironless linear generator, installable inside a wave energy converter, in order to produce electricity from sea waves. This energy source is considered strategic for the future, especially in small islands; however, this technology is still far from the commercial phase. Considering the wave energy potential of the Mediterranean Sea, a first prototype of the electrical linear generator was realized at the Department of Engineering of Palermo University. This machine can be run by a two-floating buoys system, able to produce a linear vertical motion. The main goal of this paper is the investigation of the advantages and the disadvantages of the utilization of steel materials to realize the stator of linear generators. Thus, starting from the prototype, the authors analyzed the effects produced by the replacement of steel in the stator with a non-magnetic material. For comparison, the authors evaluated the amplitude of no-load voltages, using a three-phase connection scheme, and the amplitude of the magnetic force produced by the interaction of magnets with the stator. Both aspects were evaluated through numerical simulations and mathematical models.

Нові мішені фармакологічної корекції когнітивних розладів за умов пренатальної дії гіпоксії

The review presents modern concepts of the mechanisms of brain cells damage in the conditions of prenatal action of the chronic hypoxia. Based on modern data of the adaptation mechanisms of an organism to the hypoxia state, new perspective directions for the search of effective drugs are proposed for the pharmacological correction of the prenatal hypoxia effects. Prenatal hypoxia is the most common cause of the newborns death and disability. Prenatal hypoxia leads to significant changes in the development of cognitive functions in the postnatal period of life, which are based on morphological changes in the brain structures involved in learning and memory. The results of recent years studies have made a great contribution to the disclosure of the formation mechanisms of a hypoxia state of different genesis and the metabolic and functional processes induced by it at the level of a cell and subcellular structures. A range of morphological and functional determinants (specific receptors, regulatory proteins, intracellular enzymes, mitochondrial ion channels, etc.) have been identified. They are directly involved in the development of immediate and long­term adaptation of the cell and the whole organism to hypoxia. An analysis of the literature as to studies of the molecular mechanisms of the prenatal hypoxia action showed that the basis of hypoxic damage of the newborn brain is a cascade of biochemical and molecular processes leading to excitotoxicity, oxidative and nitrosating stress and inflammation. At the same time, during hypoxia, compensatory­adaptive mechanisms begin to function, increasing the body's resistance to oxygen deficiency. In the review special attention was paid to the discussion as to the role of endogenous neuroprotection molecular determinants, such as HSP70 and HIF­1a. The HIF­1 transcriptional system is a key regulator of adaptive mechanisms of responses to hypoxia at the local and systemic levels. Changes in the expression of HIF­1 gene in prenatal development trigger the epigenetic mechanisms leading to negative changes in the nervous system development. An important component of the endogenous neuroprotective system is the HSP70 heat shock proteins family, which contributes to a wide range of processes of protein folding, refolding, membrane translocation of organellar and secretory proteins, and also controls the activity of regulatory proteins. The effect of HSP on the HIF­1 stabilization provides activation of processes of proliferation, apoptosis and angiogenesis in conditions of a hypoxia. Proteins HSP70/HIF­1a­system may be specific targets for exposure of pharmacological agents to regulate of the organism's adaptation for hypoxia. Therefore, the search of the new effective neuroprotective agents should be aimed to activation of HSP70/ HIF­1a­system and using of agents capable for providing of modulation of genes encoding the synthesis of HSP70­ and HIF­1a­ proteins.
Geochemistry and U-Pb ages of the diabases from the Luoji area, western Yunnan, China: implications for the timing of initial rifting of the Ganzi-Litang Ocean

Detailed geochemical and U-Pb studies of two diabases (Luoji and Cuiyi) from the Luoji area have been undertaken. The diabases are high-K calc-alkaline and belonging to the tholeiitic series, enriched in large ion lithophile elements, Ti, Zr and light rare earth elements, and depleted in high field strength elements. These characteristics are different from the oceanic island basalt but highly consistent with the continental rift basalt, indicating the Luoji and Cuiyi diabases are the products of the intracontinental rift related to the initial opening of the Ganzi-Litang Ocean. The Luoji and Cuiyi diabases originated from an enriched mantle source with a small degree of crustal contamination during their emplacement. Zircon U-Pb ages show that the Luoji and Cuiyi diabases were emplaced at 293.4 +/- 5.4Ma. Therefore, we propose that the time of initial rifting of the Ganzi-Litang Ocean occurred during the very Early Permian.
(Un)teaching the ‘datafied student subject’: perspectives from an education-based masters in an English university

ABSTRACT That compulsory education is datafied is widely acknowledged. A significant body of literature illuminates the policy context and technologies that have given rise to what we now call datafication. Less research has focussed on the consequences of datafication on teachers and learners. In this paper, we offer a unique perspective of these consequences in relation to qualified, experienced teachers as learners on education-based masters courses. Working within a post-qualitative frame, we employ a lesser-known approach to research, ‘conversation as methodology’, in order to explore our experiences and develop our expertise as HE practitioners. Through conversation, we identify datafication as both affective and effective – it shapes and produces particular learning and teaching encounters and it also shapes and produces subjectivities. We suggest that for education-based masters courses, this is troublesome, and can result in a process of (un)teaching, as we challenge the values and practices on which a datafied education depends.
Assessment of Morphological Traits and Fruit Metabolites in Eleven Fig Varieties (Ficus Carica L.)

ABSTRACT In the present study, morphological traits, organic acids, sugars, total phenols, total flavonoids, total anthocyanins, total anthocyanidins, antioxidant activity and color parameters such as lightness(L*), Chroma (c*) and hue angle (h°) were investigated in 11 local and introduced fig cultivars cultivated in Moroccan climate. Since only limited information on that topic is available in the literature, this study was performed in order to compare local clones with some of introduced varieties based on their morphological and biochemical attributes. Results showed highly significant differences among genotypes. The cultivar ‘Kadota’ had the most promising morphological traits. Reducing sugars levels were slightly similar among all cultivars. Thus, glucose varied from 5.55 ± 0.27 to 29.94 ± 0.81 g.kg−1 dw, while fructose amounts were in the range of 6.23 ± 0.28–28.15 ± 0.78 g.kg−1 dw. ‘Palmera’ exhibited the highest level of Malic acid (4.99 ± 0.2 g.kg−1). The latter was predominant in all cultivars. Total phenols, flavonoids and total anthocyanins were, generally, abundant in dark-colored cultivars, while total proanthocyanidins were dominant in light-colored ones. The local cultivars ‘Fassi’ and ‘Noukali’ contained the highest amounts of total phenols and total anthocyanins, respectively (524.74 ± 35.9mg GAE 100 g−1 dw and 23.77 ± 6.41 cyanidin-3-rutinoside/100 gdw). Free radical scavenging activity (DPPH and ABTS) was, generally, higher in light-colored figs, while, ferric reducing ability (FRAP) was generally higher in dark skin-colored cultivars. The study confirmed the effectiveness of combining morphological and biochemical analyses in fig assessment and its use pre-breeding programs of the species in Morocco.
The National and Religious Diversity of Siberia’s Regions

This article tests the hypothesis of higher ethnic and religious heterogeneity in Siberia when compared to Russia overall. We used the 2002 and 2010 population census and 2012 and 2015 data on religious persuasion to obtain quantitative estimates of national and religious diversity in Russia as a whole and in the region of Siberia. The analysis used indexes for heterogeneity and polarization. The results did not support the hypothesis that Siberia is distinguished by a high level of national diversity; moreover, the region is experiencing a more rapid decline in ethnic heterogeneity than Russia as a whole. The level of heterogeneity of religious beliefs in Siberia is slightly above the national average, but the trend toward greater homogeneity is also more pronounced.
The impact of sex on ropporin expression in multiple myeloma patients.

e22052 Background: Multiple myeloma (MM) is a cancer of plasma cells wherein aberrant cells accumulate in the bone marrow leading to bone damage and interference with normal blood cell production. Although MM remains incurable, it is treatable. As with most forms of cancer, early detection is the key to improving prognosis and avoiding permanent damage. Cancer Testis Antigens (CTAs) are a class of proteins that are expressed in male gametogenic tissue but generally not in the somatic tissue of healthy adults. However, a number of cancer types have been shown to produce these proteins, and their expression has been correlated with malignancy. Ropporin is a specific CTA shown to be associated with MM, and this protein represents a potential target for MM diagnosis as well as immunotherapy. In this study, we examine the impact of sex on the expression of Ropporin, in MM patients. Methods: The expression of this particular CTA in MM patients was analyzed using PCR, ELISA, and immunohistochemistry in a cohort .

Health and productivity of sheep and goats are affected greatly by superficial and deep abscesses. This study aimed to investigate the bacterial causative agents and their antibiogram of local and foreign breeds of sheep and goats abscesses in in Alhasa and Dammam areas of Kingdom of Saudi Arabia (KSA). A total of 37 and 29 species of were isolated from local and foreign breed sheep and goats abscess respectively. In local breed, Kocuria varians isolation rate was 11.67 %, then K. rosea (7.42 %), K. kristinae (6.99 %), Streptococcus uberis, Corynebacterium pseudotuberculosis , Sphingomonas paucimobilis (6.55%), C. pyogenes (3.93%) , Staph. aureus subsp. anaerobius (3.49%). In foreign breed, K. varians and K. rosea of (11.67 %), Acineto. lwoffii (7.35%), Sph. paucimobilis , Strept. uberis (5.88 %), Staph. aureus subsp. anaerobius (4.41%). This is the first report for isolation of Kocuria spp. from sheep and goats abscesses as reports of this species from animals are meagre. The prevalent isolates showed high degree of resistance to commonlyused antibiotics. Haematological analysis showed significant increase of granulocytes count (P = < .05) in the affected sheep and goats (50.3± 2.7% & 47.5± 5.8%) compared to control ones (40.6± 2.5%& 44±5.4%). In leucocytes, significant increase (P = < .05) in the affected sheep than normal animals but goats showed no difference. Contrary, the lymphocyte percentage significantly decreased ( P= < .05) in diseased sheep and goats abscesses (45.07± 1.17 %) as compared with control group (52.6 ± 1.8%). The study indicated that abscesses in sheep and goats did not affect erythrocytes count or haemoglobin content.
Features of Clinical Use of Albumin. Problems and Ways of Decision Solutions

The advantages of albumin over less costly alternative fluids continue to be debated. Many scientific articles were devoted to the clinical analysis of the use of albumin in acute illness as well as its comparison with other fluid regimens. However, the lack of fundamental knowledge about the physical and chemical properties of commercial albumin generates many unpromising discussions about the effectiveness of the use of albumin among practitioners and medical scientists. The manuscript provides information about the different variants of commercial albumin, the mechanisms of their action, indications and contraindications to use. The main purpose of this article is to objectively show the failure of generalizing conclusions and recommendations on the clinical use of commercial albumin, taking into account its various physical and chemical characteristics. To date, all studies should be conducted either in the form of a comparative analysis of a specific clinical effect, or within the framework of studies of only one brand of albumin. Otherwise, generalizing the conclusions, the recommendations on the use of different forms of albumin are not correct and generate a lot of useless of the discussions. The presented information is based on fundamental knowledge of physical and chemical properties of commercial albumin. This manuscript is not only educational information, but also is scientific guide for clinicians.
