Molecular modeling and experimental studies on structure and NMR parameters of 9-benzyl-3 , 6-diiodo-9 H-carbazole

A combined experimental and theoretical study has been performed on 9-benzyl-3,6-diiodo-9H-carbazole. Experimental X-ray (100.0 K) and room-temperature C nuclear magnetic resonance (NMR) studies were supported by advanced density functional theory calculations. The non-relativistic structure optimization was performed and the C nuclear magnetic shieldings were predicted at the relativistic level of theory using the zeroth-order regular approximation. The changes in the benzene and pyrrole rings compared to the unsubstituted carbazole or the parent molecules were discussed in terms of aromaticity changes using the harmonic oscillator model of aromaticity and the nucleus independent chemical shift indexes. Theoretical relativistic calculations of chemical shifts of carbons C3 and C6, directly bonded to iodine atoms, produced a reasonable agreement with experiment (initial deviation from experiment of 41.57 dropped to 5.6 ppm). A good linear correlation between experimental and theoretically predicted structural and NMR parameters was observed. Graphical Abstract
Antifibrotic Effect of Standardized Ethanol Extract of Tithonia diversifolia ( Hemsley ) A . Gray on Keloid Fibroblasts

Keloid occurred by abnormal wound healing, characterized by massive fibroblast proliferation and excessive collagen accumulation. Therapy for keloid is relatively limited and mostly has side effects. Tithonia diversifolia has widely been studied for having anti-proliferative effect against some cancer cells in vitro. This study was conducted to assess T. diversifolia potential as an antifibrotic agent. Antifibrotic activity of standardized ethanolic extract of T. diversifolia leaf on cell proliferation of keloid fibroblasts and its collagen accumulation were expressed by IC50 values using probit regression analysis. Keloid fibroblast proliferation inhibition percentage was elevated gradually along with the given doses of T. diversifolia extract with very strong correlation (r=0.838;p=0.000 in 72 hours; r=0.924;p=0.000 in 120 hours of incubation) with the lowest IC50 value 3.624 μg/mL in 120 hours incubation time. There was also significant timedependent effect (p=0.005). As well for collagen accumulation with moderate correlation (r=-0.797;p=0.000 for 72 hours incubation time; r=-0.583;p=0.000 for 120 incubation time) with lowest IC50 value 2.280 μg/mL in 120 hours incubation time. This study concluded that the ethanol extract of T. diversifolia is potential to be developed as antikeloid in the future although some additional data such as toxicity and clinical study.
Prediction of the Pollutants Concentration Using Artificial Neural Network ( ANN )

Air pollution is one of the most important environmental issues that annual causes to mortality large number of people around the world. So, investigating, measuring, and predicting the concentrations of different pollutants in various areas play an important role in preventing the production of this pollutant sand planning to reduce them by people and relevant authorities. One of the new models that play an important role in measuring and predicting pollution is artificial neural network or regression methods. Therefore, this study is trying to predict air pollution in Yasouj by using artificial neural network in 2014. Because the evidences showed that Yasouj due to uncontrolled growth of industrial and urban transport is subject to various air pollutants such as carbon monoxide and particulate matter. Overall, the results of the assessment and prediction of concentration of pollutants of Yasouj by artificial neural network showed that sigmoid transfer function to the hyperbolic tangent function is more efficient in measuring the concentration of pollutants.
All Things Considered: An Analysis of IoT Devices on Home Networks

In this paper, we provide the first large-scale empirical analysis of IoT devices in real-world homes by leveraging data collected from user-initiated network scans of 83M devices in 16M households. We find that IoT adoption is widespread: on several continents, more than half of households already have at least one IoT device. Device types and manufacturer popularity vary dramatically across regions. For example, while nearly half of North American homes have an Internet-connected television or streaming device, less than three percent do in South Asia where the majority of devices are surveillance cameras. We investigate the security posture of devices, detailing their open services, weak default credentials, and vulnerability to known attacks. Device security similarly varies geographically, even for specific manufacturers. For example, while less than 17% of TP-Link home routers in North America have guessable passwords, nearly half do in Eastern Europe and Central Asia. We argue that IoT devices are here, but for most homes, the types of devices adopted are not the ones actively discussed. We hope that by shedding light on this complex ecosystem, we help the security community develop solutions that are applicable to today’s homes.
In Vitro Anti-Adherence Effect of Probiotic Lactobacillus Strains on Human Enteropathogens

Probiotic bacteria possess great potential for producing antimicrobial substances that inhibit and control pathogenic bacteria in the human gastrointestinal tract. The aim of this study was to determine the anti-adherence properties of the probiotic Lactobacillus strains Lb. rhamnosus ŁOCK 0900, Lb. rhamnosus ŁOCK 0908, and Lb. casei ŁOCK 0919 (individually and in a 1:1:2 mixture) against the reference pathogens Clostridium difficile (ATCC 9689), Enterococcus faecalis (ATCC 29212), Listeria monocytogenes (ATCC 19115), and Staphylococcus aureus (ATCC 6538) using the Caco-2 human colon adenocarcinoma cell line. The mixture of probiotic strains inhibited the adherence of all pathogens, from 10.2% for E. faecalis ATCC 29212 to 97.2% for L. monocytogenes ATCC 19115. Of all the tested probiotic strains, Lb. casei ŁOCK 0919 reduced the adherence of S. aureus ATCC 6538 to the greatest extent (by 45.9%). These results suggest that adherence inhibition may involve competition for eukaryotic cell receptors and probiotic bacteria could protect the host cells from pathogen colonization and disease.
Dynamics of a Well-Diversified Equity Index January 17 , 2019

The paper derives a parsimonious model for the long-term dynamics of a well-diversified stock index, the S&P500. The index is modeled as growth optimal portfolio. Its normalized value evolves, in some market time, as a square root process. The derivative of market time is a linear function of the squared derivative of a smoothed proxy of the single driving Brownian motion. The model explains the feedback effects from index moves typically observed for monthly and daily S&P500 values. It is highly tractable, permits almost exact simulation and leads beyond classical assumptions in finance.
Torino Hill ( Tertiary Piedmont Basin , northwestern Italy )

Geologic mapping and integrated stratigraphic and structural observations of a gypsum quarry from northwestern Italy allow evaluation of the relative contributions, the time relationships, and the causative links between tectonic, sedimentary, and diapiric processes in the genesis of chaotic sediments of Messinian age. Three chaotic units are exposed in the quarry: together, they make up a composite chaotic unit that is unconformably overlain by post-chaotic sediments. Unit 1 is composed of blocks of primary evaporites that are juxtaposed to marine marls by subvertical transpressive faults and are parallel to the fault surfaces. Unit 2 unconformably overlies Unit 1, and consists of a lenticular sedimentary body containing both angular and rounded blocks, randomly distributed in a fine-grained matrix. Unit 3 consists of a 10-m-wide body bounded by transpressive faults, and pierces both Units 1 and 2. It is composed of strongly deformed muddy deposits that envelop blocks of gypsum and carbonate rocks. Between the core and the margins, various zones have been defined based on the increasing amount of deformation toward the margins. The postchaotic sediments unconformably overlie both Units 1 and 2, sealing the main fault systems. The composite chaotic unit is related to thrust propagation during a regional phase of deformation, and is the result of different evolutionary stages, in each of which a single genetic mechanism prevailed. Tectonic faulting prevailed during stage 1 and was responsible for the formation of a tectonically disrupted assemblage (Unit 1). During stage 2, gravity-driven sedimentary phenomena, related to slope oversteepening triggered by ongoing thrust propagation, resulted in the deposition of Unit 2. Gravity sliding was favored by the mechanical weakening of sediments caused by tectonic faulting. Overpressure conditions resulting from the rapid deposition of Unit 2 triggered the rise of a diapir (Unit 3) that pierced Units 1 and 2. The involvement of methane-rich fluids in the formation of the diapir is suggested by the occurrence of blocks of methane-derived carbonates, found not in the quarry, but just outside it.
Biometry and Security-Seminar Report Fingerprint-based Fuzzy Vault : Implementation and Performance

Since the introduction of new cryptographic construct named fuzzy vault back in 2002, there has been several successful implementations and evaluations of it. Implementation presented in this report builds upon strengths and weaknesses of past solutions and adds an important improvement to the implementation automatic alignment of template and query fingerprint minutiae. To facilitate this alignment, authors have used high curvature points, derived from fingerprint orientation field, as helper data. This data doesn’t leak any information about template minutiae, as high curvature points are global features of a fingerprint. Authors have also evaluated the performance of proposed fuzzy vault. They showed considerable improvements in comparison to other approaches. On the other hand, discussion about security of this implementation of fingerprint fuzzy vault is questionable, since it is known fact today that fuzzy vault is vulnerable to brute force attack.
AutoCorrect: Deep Inductive Alignment of Noisy Geometric Annotations

We propose AutoCorrect, a method to automatically learn object-annotation alignments from a dataset with annotations affected by geometric noise. The method is based on a consistency loss that enables deep neural networks to be trained, given only noisy annotations as input, to correct the annotations. When some noise-free annotations are available, we show that the consistency loss reduces to a stricter self-supervised loss. We also show that the method can implicitly leverage object symmetries to reduce the ambiguity arising in correcting noisy annotations. When multiple object-annotation pairs are present in an image, we introduce a spatial memory map that allows the network to correct annotations sequentially, one at a time, while accounting for all other annotations in the image and corrections performed so far. Through ablation, we show the benefit of these contributions, demonstrating excellent results on geo-spatial imagery. Specifically, we show results using a new Railway tracks dataset as well as the public INRIA Buildings benchmarks, achieving new state-of-the-art results for the latter.
Title CFT descriptions of bulk local states in the AdS black holes

We present a new method for reconstructing CFT duals of states excited by the bulk local operators in the three dimensional AdS black holes in the AdS/CFT context. As an important procedure for this, we introduce a map between the bulk points in AdS and those on the boundary where CFT lives. This gives a systematic and universal way to express bulk local states even inside black hole interiors. Our construction allows us to probe the interior structures of black holes purely from the CFT calculations. We analyze bulk local states in the single-sided black holes as well as the double-sided black holes.
Is the age difference between partners related to women's earnings?

Background: Women earn less than men at most career stages. Explanations for a gender gap in wages include gender differences in the allocation of household and domestic work. At the family level, a marital age difference is an important shared characteristic that might play a role in determining a woman’s career trajectory, and, therefore, her income. Since women tend to marry older men, we investigate whether women whose husbands are older have lower incomes than women whose husbands are the same age or younger. Objective: This study investigates whether the age gap between a woman and her partner was associated with her income in Denmark in 2010. Methods: We use data on Danish female twin pairs in 2010. Our design includes samples within twin pairs (n = 4,716) and pooled twin samples (n = 13,354) to account for differences in early household environments and uses unconditional quantile regression to model the association between the age gap and the woman's income. Results: We find a statistically significant association between the marital age gap and the woman's income. The form of this association appears to be complex and varies across the income and age gap distribution. However, the magnitude of the estimated effects is small in economic terms. Conclusions: These results suggest that the marital age gap is unlikely to be an important determinant of a woman’s income, at least in Denmark. Contribution: To our knowledge, this is the first study that explores the association between marital age differences and a woman's earnings using a twin design and high-quality register data.
IMPORTANCE OF BITUMEN PHYSICAL HARDENING FOR THERMAL STRESS BUILDUP AND RELAXATION IN ASPHALT

Bitumen is known to undergo significant time-dependent stiffening when stored at low temperatures. This phenomenon, often referred to as physical hardening, has been shown to have significant impact on the laboratory performance of bitumen. However, the importance of isothermal conditioning for asphalt and its effect on thermal cracking performance has been a subject of debate. This paper investigates the effects of cooling rate and isothermal conditioning on thermal stress buildup and relaxation of different asphalt materials obtained from field pavement sections in MnROAD, Minnesota, USA. A relatively simple device was developed and used to simultaneously test two asphalts beams: a unrestrained beam from which the change in volumetric properties with temperature, and consequently the glass transition temperature (Tg) and coefficients of expansion/contraction, are measured; and a restrained beam used to measure thermal stress buildup. Test performed at different cooling rates and various relaxation periods showed that at high cooling rates, isothermal contraction significantly affects the rate of thermal stress buildup. Furthermore, contrary to the expectation of full stress relaxation for visco-elastic materials, the thermal stress in restrained samples held at isothermal conditions for extended periods of time did not completely relax, converging to a constant residual stress. Fracture of specimens held isothermally occurred at a temperature higher than fracture temperature measured when specimen is monotonically cooled down. These results indicate that physical hardening may be responsible for unexpected thermal cracking observed in the field. The findings show the need to measure the glass transition of bitumen, their behavior under isothermal conditioning, and the use of realistic cooling rates for better prediction of thermal cracking.

Implementation of Wide Area Measurement System in Slovenian Transmission System

Maintaining a reliability of power supply is essential for each utility. Therefore events leading to outages in power systems have to be avoided. Blackouts, voltage collapses and cascade tripping are mainly caused by wide area disturbances, such us voltage instability, frequency instability, etc. Phasor measurement units enable real-time monitoring of the power system. Real-time collection of phasor measurements from the power system into a central unit together with complex analysis offer a possibility for wide-area monitoring, protection and control.
Designing an Electronic Communication Resource : a Practical Experience of Shaping Advanced Professional Competencies for Future Teachers ∗

Developing digital society sets forth advanced professional teacher competencies, with a transdisciplinary approach to mediated communication multilingual and multicultural abilities, interpersonal skills, telecollaboration and co-working. The paper presents a two-step model proposed for preparing students of pedagogical education direction to design a communication resource. Firstly, students were invited to act as participants in an already designed resource. Secondly, they were offered to develop their own communication resource and to involve other participants in the discussion based on it. When designing a communication resource, students used a small variety of communication algorithms, but a wide variety of discourse enhancement techniques. The experience shows that designing a communication resource gives students an opportunity to practice space, time and speech capabilities together with limitations, risks, communication and technological features of mediated communication that is beneficial for acquiring advanced professional com-
Circulating miR-665 and miR-30 c-1-3 p , the candidate markers of congestive heart failure with qi-deficiency-blood-stasis syndrome

According to the Chinese medicine (CM) theory, qi-deficiency-blood-stasis syndrome might be one of major patterns of congestive heart failure (CHF), but the underlying mechanism is yet not clear. Here, we aim to investigate the role of microRNAs (miRNAs) in the regulation of CHF in the presence of qi-deficiency-blood-stasis syndrome. We tested miRNAs expression microarray on the serum samples from CHF patients (three patients with qi-deficiencyblood-stasis syndrome, and three without), the significant different expressed miRNAs (DE-miRNAs) were screened and further quantified by RT-PCR in tissue samples. Target genes of these DE-miRNAs were analyzed using the software and miRNAs database, which could predict the relations between these DE-miRNAs and CHF mediated by qi-deficiency-blood-stasis syndrome. A total of 9 DE-miRNAs were confirmed, among them, miR-665 and miR-30c-13p draw specific attention. Because pathway analysis revealed that both miR-665 and miR-30c-1-3p target on the zinc finger protein 460 and 880, which translocated into nuclear and activated GATA4 transcription factor, the later was important for cardiac development survival and hypertrophy, therefore the upregulation of DE-miRNAs might be a biomarker to predict the progression of CHF. The occurrence and development of CHF may result from certain DE-miRNAs and their target genes participating in several signal pathways. MiR-665 and miR-30c-1-3p may be the candidate markers for the risk of congestive heart failure in Qi-deficiency-blood-stasis Syndrome.

Judicial torture to extract information or to elicit a confession was a common practice in pre-modern societies, both in the east and the west. This paper proposes a positive theory for judicial torture. It is shown that torture reflects the magistrate’s attempt to balance type I and type II errors in the decision-making, by forcing the guilty to confess with a higher probability than the innocent, and thereby decreases the type I error at the cost of the type II error. Moreover, there is a non-monotonic relationship between the superiority of torture and the informativeness of investigation: when investigation is relatively uninformative, an improvement in technology used in the investigation actually lends an advantage to torture so that torture is even more attractive to the magistrates; however, when technological progress reaches a certain threshold, the advantage of torture is weakened, so that a judicial system based on torture becomes inferior to one based on evidence. This result can explain the historical development of the judicial system.
Frequency Reconfigurable Millimeter-Wave Antenna Design for 5 G Application

This paper addresses frequency reconfigurable U-shaped patch antenna that can operate at Kaband of 26.5 GHz to 40 GHz for the 5 th Generation (5G) application. The effective length of antenna current is controlled using the MEMS switch mounted in between two L-shape strips forming the U structure with square shape wing patch. Inductive and capacitive coupling between the two L-patches helps in achieving two-frequency band reconfiguration. When the switch opens for the OFF condition both the asymmetrical L-shaped patch get capacitive coupled along with the square shaped wing as before. Geometrical shape and size of the substrate is exactly the same as the black coloured patch. Dielectric constant has been appreciably reduced by using RT Rogers-air combination as substrate. Antenna gain of 9dB is obtained for the two frequency band at par with other standard works. Total efficiency falls in the range of 70-75%, VSWR in between 1-2. Key radiation patterns are also described in the paper.
