INTEGRATION OF GEOMATICS TECHNIQUES FOR DIGITIZINGHIGHLY RELEVANT GEOLOGICAL AND CULTURAL HERITAGE SITES:THE CASE OF SAN LEO (ITALY)

Abstract. The research activities described in this contribution were carried out at San Leo (Italy). The town is located on the top of a quadrangular rock slab affected by a complex system of fractures and has a wealth of cultural heritage, as evidenced by the UNESCO’s nomination. The management of this fragile set requires a comprehensive system of geometrical information to analyse and preserve all the geological and cultural features. In this perspective, the latest Geomatics techniques were used to perform some detailed surveys and to manage the great amount of acquired geometrical knowledge of both natural (the cliff) and historical heritage. All the data were also georeferenced in a unique reference system. In particular, high accurate terrestrial laser scanner surveys were performed for the whole cliff, in order to obtain a dense point cloud useful for a large number of geological studies, among others the analyses of the last rockslide by comparing pre- and post-event data. Moreover, the geometrical representation of the historical centre was performed using different approaches, in order to generate an accurate DTM and DSM of the site. For these purposes, a large scale numerical map was used, integrating the data with GNSS and laser surveys of the area. Finally, many surveys were performed with different approaches on some of the most relevant monuments of the town. In fact, these surveys were performed by terrestrial laser scanner, light structured scanner and photogrammetry, the last mainly applied with the Structure from Motion approach.
Distinguishing cells by their first-order transient motion response under an optically induced dielectrophoretic force field

This letter reports our characterization of the transient motion of cells under an optically induced dielectrophoresis (ODEP) force field. Different types of human cells repeatably undergo a first-order transient motion response when subjected to a specific ODEP force field. A kernel function is derived to describe this transient motion. This function can be generally matched to experimental data for Raji cells and red blood cells by measuring two parameters: the initial velocity and the transient time-constant. They are uniquely different for Raji cells and RBCs. Support vector machine is used to distinguish between them based on their transient response characteristics.
Sheep and goat preferences for Mediterranean fodder shrubs. Relationship with the nutritive characteristics.

Palatability of six Mediterranean fodder shrubs was measured on stall-fed sheep and goats. The ratio I7/D7 (average amount of shrub consumed over the 7-day period to average amount of shrub distributed over the 7-day period) was used as a palatability index. Goat consumed more shrubs than sheep. Sheep and goat preferences for shrubs were different. Shrub intake (I7) by sheep was not related to their chemical composition. In contrast, palatability was significantly correlated to dry matter (I7/D7 = –0.76 DM + 67.1, r = 0.70, P < 0.01), ash (I7/D7 = 1.92 Ash + 16.1, r = 0.75, P < 0.001), phosphor (I7/D7 = 52.2 P + 22.8, r = 0.54, P < 0.05) and sodium (I7/D7 = 5.3 Na + 26.3, r = 0.67, P < 0.01) contents. Goat preferred less fibrous (I7/D7 = 2.8 ADL + 76.6, r = –0.59, P < 0.05) and sodium rich shrubs (I7/D7 = 15.0 Na + 19.1, r = 0.62, P < 0.01). Sheep and goat preferences were not dependent upon condensed tannin content of shrubs. Shrub intake by sheep and goats (I7) was not related to biological parameters (DM in vitro digestibility and in sacco degradability, and gas production). These parameters seem to have no effect on goat preferences. In contrast, sheep preferences for shrubs was correlated to DM in vitro digestibility (I7/D7 = 0.6 dDMvitro + 11.6, r = 0.52, P < 0.05).
Chloramphenicol Mitigates Oxidative Stress by Inhibiting Translation of Mitochondrial Complex I in Dopaminergic Neurons of Toxin-Induced Parkinson's Disease Model

Paraquat (PQ), an herbicide considered an environmental contributor to the development of Parkinson's disease (PD), induces dopaminergic neuronal loss through reactive oxygen species (ROS) production and oxidative stress by mitochondrial complex I. Most patients with PQ-induced PD are affected by chronic exposure and require a preventive strategy for modulation of disease progression. To identify drugs that are effective in preventing PD, we screened more than 1000 drugs that are currently used in clinics and in studies employing PQ-treated cells. Of these, chloramphenicol (CP) showed the most powerful inhibitory effect. Pretreatment with CP increased the viability of PQ-treated SN4741 dopaminergic neuronal cells and rat primary cultured dopaminergic neurons compared with control cells treated with PQ only. CP pretreatment also reduced PQ-induced ROS production, implying that mitochondrial complex I is a target of CP. This effect of CP reflected downregulation of the mitochondrial complex I subunit ND1 and diminished PQ recycling, a major mechanism of ROS production, and resulted in the prevention of cell loss. Notably, these effects of CP were not observed in rotenone-pretreated SN4741 cells and Rho-negative cells, in which mitochondrial function is defective. Consistent with these results, CP pretreatment of MPTP-treated PD model mice also ameliorated dopaminergic neuronal cell loss. Our findings indicate that the inhibition of mitochondrial complex I with CP protects dopaminergic neurons and may provide a strategy for preventing neurotoxin-induced PD.
Investigation of Bioactive Compounds on Relict Endemic Ajuga relicta P. H. Davis (Lamiaceae) from Turkey

Species belonging to genus Ajuga (Lamiaceae) have been used to treat many diseases in traditional medicine. The plants of the genus Ajuga have been reported to have antifungal, antibacterial, antimycobacterial, antihypertensive, antiplasmodial, hypoglycaemic, and larvae and insect activity. Ajuga relicta is a relict endemic plant which grows only in Kahramanmaras. The total phenolic contents of the extracts have been quantified with Folin Ciocalteu colorimetric method, and the antioxidant activities of the extracts have been tested with DPPH, and FRAP. Antimicrobial activities of plant extracts were determined by the well-diffusion method against seven bacteria and four yeasts. Besides, the fatty acid composition was determined in GC-MS. As a result of GC-MS analysis of the oil obtained from the A. relicta extracts, 21 different fatty acids were identified. The highest contents of these fatty acids were palmitic acid (29.50%), oleic acid (23.51%), stearic acid (9.13%) and linoleic acid (7.18%). Total phenolic value of plant extract was 11.94 mg/g, total flavonoid amount 2.28 mg/g, FRAP value 43.53 μg/g and DPPH value 1.63 mg/g. Antimicrobial activity experiment on a total of 11 microorganisms (seven bacteria and four yeast) showed that Ajuga extracts inhibited the growth of tested microorganisms except Enterobacter cloacae, Candida glabrata and Saccharomyces cerevisiae . A. relicta was found to have high bioactive content and antimicrobial activity. The plant extracts are rich in constant fatty acids and similar to olive oil (palmitic-oleic-linoleic), which is well known for its health benefits in terms of major fatty acids.
Application of the NMR technique for the analysis of the water state in pickled and plasticized muscles of large slaughter animals

Ab s t r a c t . The paper presents an analysis of the phy sical and chemical parameters determining the state of water in musculus longissimus dorsi and musculus semimembranosus pork and beef muscles in the course of the pickling process and t he plasticization and pasteurization processes. Values of the relaxation times for the spin-lattice T1 and spin-spin T2, pH values, water activity, as well as the content of free water and total water c ontent were determined. Depending on the stage of the experiment, measurements of the spin-spin relax ation times revealed the presence in the examined muscles of free and bound water fractions of various levels of mobility. It was found that the massaging process changes the proportion of the free water and bound water obtained by NMR method. But its molecular dynamics was reduced considerably. In comparison with pickling, the pasteurization process did not change the value of water activity. However, the total water content in muscles decreased, while the content of free wat er was found increased considerably.
Lost in Transaction: Individual-Level Welfare Loss in Quickly-Circulating Durable Goods Markets with Planned Temporary Ownership

A new style of durable goods consumption through a large scale online redistribution marketplace (e.g. eBay and Yahoo! Auction), characterized by a relatively small degree of usage and a short-term ownership, is becoming increasingly popular these days. Yet, the market and welfare structures of such emerging markets have not been investigated. By using a unique dataset of quickly-circulating multi-use train ticket resale markets, this short article models, estimates, and analyzes individual-level welfare loss in such rapidly-growing market sectors. Our analysis shows that the individual-level welfare loss caused by resale market friction costs is non-negligibly large, ranging from 3% to 15% of the new good price. We also find that such individual-level welfare losses, which could be considered as hidden charges, are largely heterogeneous across buyers with differing degrees of intended use, described as disadvantageous to users who demand light degrees of usage.
Strategies to improve native bee (Hymenoptera: Apoidea) habitat in agroecosystems

Landscapes dominated by agriculture offer little vegetative heterogeneity and are frequently disturbed by farming practices. In Iowa, 72% of the land is devoted to the production of corn (Zea mays L.) and soybean (Glycine max L.), neither of which require animal-mediated pollination, thus provide few resources for pollinators. An approach to mitigating the negative impacts of highly intensive agricultural practices on the surrounding landscape is the implementation of Conservation Reserve Program (CRP) contour buffer and filter strips within agricultural fields. This study assessed the impact of such strips with varying plant diversities on the local native bee communities. Surveys of bee communities were conducted at eleven sites throughout Iowa using traps (bowl, blue vane, and emergence) and netting techniques. Vegetation surveys were also conducted to determine blooming floral diversity within the strips at each site. After five years of surveys, we found statistically significant relationships between native bee abundance and floral coverage within the strips as well as between bee species richness and floral species richness. Additionally, in the third year of the study, we established experimental plots of bare ground within flight distance of the strips to serve as potential nesting habitat for ground-nesting bees. In subsequent evaluations of these plots, we collected 330 individual bees representing 30 species. Based on these results, it is clear that contour buffer and filter strips with greater blooming floral diversity have the potential to offer quality forage and establishing bare soil plots increases nesting resource availability, ultimately supporting bee communities of greater diversity than areas lacking these essential habitat components. Furthermore, we wanted to address the floral species included in seed mixes intended to support bees. Using a targeted-sweeping method, in which a bee was
The Function of lncRNAs as Epigenetic Regulators

Recently, the non-coding RNAs (ncRNAs) have been classified in different categories, and its importance in regulating different cellular processes has been unravelled. The long non-coding RNAs (lncRNAs) can interact with DNA, other RNAs and proteins, including epigenetic modifiers. Some lncRNAs are related to genomic imprinting and are associated with chromatin-modifying complexes that can regulate gene transcription. It is well established that cancer cells have different epigenetic alterations and some of these modifications are associated with lncRNAs. Studies of cancer-associated lncRNAs have defined its function in the process of tumorigenesis, its impact on cell proliferation, cellular signalling, angiogenesis and metastasis. Therefore, having a better knowledge of their role might contribute to a better understanding of the diseases. In this chapter, we will discuss about lncRNA classification and functions, epigenetic marks and how they can guide transcription. Nevertheless, we will discuss how these mechanisms can interact and guide gene expression, as well as recently findings of dysregulation of lncRNAs in cancer.
Acta Polytechnica

Understanding the mechanical behavior of carbon fiber reinforced polymers requires knowledge on the deformation behavior of carbon fibers, they are highly anisotropic and heterogeneous. Nanoindentation is an efficient method for determining the mechanical properties in small volumes of materials. For isotropic materials, a single nanoindentation test can evaluate an elastic properties of the material. But for anisotropic material, the difficulty increases since measured indentation modulus depends on five elastic parameters (El, Et, Glt, νlt,and νtt) of the material. Nanoindentation experiments are performed on carbon fibers orientated between 0◦ to 90◦ at ten different orientations to the fiber axis. From theoretical models given by Vlassak et al. and Delafargue and Ulm, the elastic constants are predicted numerically by comparing the results of indentation modulus versus orientation angle with the experiments.
Molecular cloning of the gene encoding pregnane X receptor ( PXR ; NR 1 I 2 ) and the constitutive androstane receptor ( CAR ; NR 1 I 3 ) in pigs

The pregnane X receptor (PXR; NR1I2) and the constitutive androstane receptor (CAR; NR1I3) are members of the nuclear receptor superfamily that act as transcription factors. They regulate the expression of several important genes that encode enzymes responsible for the metabolism of endogenous hormones and exogenous substances. We determined the nucleotide sequences of porcine CAR and PXR genes bp using cDNA clones derived from porcine cDNA libraries. The porcine CAR gene has a 1407 bp mRNA, which contains a 216 bp 5'-untranslated region (UTR), a 144 bp 3'-UTR, and a 1047 bp coding region that encodes 348 amino acids. The mRNA sequence of porcine PXR is composed of 2567 bp that contains a 273 bp 5'-UTR, a 1266 bp putative coding region encoding 421 amino acids, and a 1028 bp 3'-UTR. The porcine CAR and porcine PXR proteins showed a high degree of sequence identity in their DNA-binding domain (DBD) and ligand-binding domain (LBD) with 80% 90% amino acid identity in comparison with those of humans. However, the AB domain of the porcine CAR and PXR proteins is considerably different in comparison with that of humans. Eighty six percentage and 43 % sequence identity is found between porcine and human CAR proteins and porcine and human PXR proteins, respectively. The mRNA expression of both porcine CAR and PXR was detected in liver, small intestine, and kidney bp using reverse-transcription (RT)-PCR.
The Effects of Changing Technology: The Impacts of a Changing Cost Structure on Land Tenure Arrangements in the Mississippi Delta, 1996 - 2004

Genetically modified (GM) cotton varieties have changed many aspects of cotton production in the United States. The advent of GM varieties has fueled the ongoing trend of increasing farm size and fewer farmers. Mississippi is no exception to this trend. The rapid adoption of GM cotton varieties in Mississippi has allowed some producers to increase the acreage of their farming operation. This study analyses the impact of GM varieties on relative profitability over certain types of land tenure arrangements. The type of land tenure arrangement and the cost associated with the arrangement are compared to determine relative probabilities of breaking even for different farm sizes in the Mississippi cotton industry.
Thank you for your comments concerning our manuscript entitled “Second-order Scalar Wave

The forward modeling of a scalar wave equation plays an important role in the numerical 7 geophysical computations. The finite-difference algorithm in the form of a second-order wave equation is one 8 of the commonly used forward numerical algorithms. This algorithm is simple and is easy to implement based 9 on the conventional-grid. In order to ensure the accuracy of the calculation, absorption layers should be 10 introduced around the computational area to suppress the wave reflection caused by the artificial boundary. 11 For boundary absorption conditions, a perfectly matched layer is one of the most effective algorithms. 12 However, the traditional perfectly matched layer algorithm is calculated using a staggered-grid based on the 13 first-order wave equation, which is difficult to directly integrate into a conventional-grid finite-difference 14 algorithm based on the second-order wave equation. Although a perfectly matched layer algorithm based on 15 the second-order equation can be derived, the formula is rather complex and intermediate variables need to be 16 introduced, which makes it hard to implement. In this paper, we present a simple and efficient algorithm to 17 match the variables at the boundaries between the computational area and the absorbing boundary area. This 18 new boundary matched method can integrate the traditional staggered-grid perfectly matched layer algorithm 19 and the conventional-grid finite-difference algorithm without formula transformations, and it can ensure the 20 accuracy of finite-difference forward modeling in the computational area. In order to verify the validity of our 21 method, we used several models to carry out numerical simulation experiments. The comparison between the 22 simulation results of our new boundary matched algorithm and other boundary absorption algorithms shows 23 that our proposed method suppresses the reflection of the artificial boundaries better and has a higher 24 computational efficiency. 25

Bloch oscillations of Bose-Einstein condensates: Quantum counterpart of dynamical instability

We study the Bloch dynamics of a quasi-one-dimensional Bose-Einstein condensate of cold atoms in a tilted optical lattice modeled by a Hamiltonian of Bose-Hubbard type. The corresponding mean-field system described by a discrete nonlinear Schr\"odinger equation can exhibit dynamical (or modulation) instability due to chaotic dynamics and equipartition over the quasimomentum modes. It is shown that these phenomena are related to Bogoliubov's depletion of the Bose-Einstein condensate and a decoherence of the condensate in the many-particle description. Three types of dynamics are distinguished: (i) decaying oscillations in the region of dynamical instability and (ii) persisting Bloch oscillations or (iii) periodic decay and revivals in the region of stability.
3 1 Ja n 20 18 FALKON : An Optimal Large Scale Kernel Method

Kernel methods provide a principled way to perform non linear, nonparametric learning. They rely on solid functional analytic foundations and enjoy optimal statistical properties. However, at least in their basic form, they have limited applicability in large scale scenarios because of stringent computational requirements in terms of time and especially memory. In this paper, we take a substantial step in scaling up kernel methods, proposing FALKON, a novel algorithm that allows to efficiently process millions of points. FALKON is derived combining several algorithmic principles, namely stochastic subsampling, iterative solvers and preconditioning. Our theoretical analysis shows that optimal statistical accuracy is achieved requiring essentially O(n) memory and O(n √ n) time. An extensive experimental analysis on large scale datasets shows that, even with a single machine, FALKON outperforms previous state of the art solutions, which exploit parallel/distributed architectures.
Metal Abundances of KISS Galaxies. VI. New Metallicity Relations for the KISS Sample of Star-forming Galaxies

We present updated metallicity relations for the spectral database of star-forming galaxies (SFGs) found in the KPNO International Spectroscopic Survey (KISS). New spectral observations of emission-line galaxies obtained from a variety of telescope facilities provide oxygen abundance information. A nearly fourfold increase in the number of KISS objects with robust metallicities relative to our previous analysis provides for an empirical abundance calibration to compute self-consistent metallicity estimates for all SFGs in the sample with adequate spectral data. In addition, a sophisticated spectral energy distribution fitting routine has provided robust calculations of stellar mass. With these new and/or improved galaxy characteristics, we have developed luminosity–metallicity (L–Z) relations, mass–metallicity (M*–Z) relations, and the so-called fundamental metallicity relation (FMR) for over 1450 galaxies from the KISS sample. This KISS M*–Z relation is presented for the first time and demonstrates markedly lower scatter than the KISS L–Z relation. We find that our relations agree reasonably well with previous publications, modulo modest offsets due to differences in the strong emission line metallicity calibrations used. We illustrate an important bias present in previous L–Z and M*–Z studies involving direct-method (Te) abundances that may result in systematically lower slopes in these relations. Our KISS FMR shows consistency with those found in the literature, albeit with a larger scatter. This is likely a consequence of the KISS sample being biased toward galaxies with high levels of activity.
