Compressive Sensing-Based Underground Channel Estimation Operating in Millimetter-Wave Band

Propagation in underground mine environment, especially for millimeter-Wave (mm-Wave) band is envisioned as one of the most challenging communication systems. An efficient channel estimation is made critical for 60 GHz communications, because this, high-resolution step can significantly enhance the stability and the data rates of the communication system. This paper investigates a promising compressed sensing (CS) based underground channel estimation scheme in time domain for $ 2\times 2$ multiple-input-multiple-output (MIMO) system operating in the 60 GHz band. Motivated by the observation that the mm-Wave channel is prone to exhibit sparsity, this architecture is applied on channel measurements which are performed in real MIMO underground mine environments, by skillfully designing the pilots within the frame. This work is considered to be the first investigation that estimated the underground radio channel based on real-world propagation measurements at this band. We have retained the conventional least squares (LS) as the benchmark to show that the CS estimator technique achieves a higher estimation accuracy than the former in terms of both the normalized mean square error (NMSE) and the bit error rate (BER).

Improvement in Performance of Induction Heating System Using Direct AC-AC Boost Converter

Due to the unique advantages of induction heating (IH), it becomes the current technology of choice in the modern domestic application. So for designing of this system, efficiency is the key parameters which improve the performance of whole IH system. In order to achieve this goal, a direct AC-high frequency AC Boost converter is presented which converts utility AC to HFAC in a single stage conversion. Also, it reduces the component counts and stress level of voltage/current across the switches. This proposed topology is designed for 2.5 kW and verified through MATLAB/SIMULINK environment with extensive studies of simulation results.
DFT Study of Thermoelectric Performance of SrTiO3 Doped by Tantalum

This paper deals with enhancement of thermoelectric performance of SrTiO3 a perovskitebased material by doping Ti-site with Ta. The electronic and the thermoelectric transport properties of doped SrTiO3 were studied using the first principle calculation in fullpotential of density functional theory. Spin-orbit coupling including Hubbard U parameter influences were observed in the investigation. Energy band structure and electron density of state were determined for electronic properties. The Seebeck coefficients, thermal conductivity, electrical conductivity as well as thermoelectric efficiency ZT were calculated for thermoelectric properties. The results of our calculations revealed that narrowing the bandgap of the material leads to the increase of thermoelectric efficiency ZT. At spin-orbit coupling with DFT+U method, ZT of 0.18 at 750 K were obtained and this is similar to the experimental data reported.

Binary Obfuscation Based Reassemble

Software reverse engineering is the process of retrieving the source code or recovering the higher level structure from an executable binary file. It has a wide range of applications in software analysis, such as vulnerability mining and exploiting, blind patching and so on. But it can also be used for illegal activities such as software piracy and plagiarism, which bring huge losses to relevant workers. So Anti-reverse has important significance for intellectual property protection. In fact, it is difficult to protect a software against being reversed or malicious modifications.In this paper, we present and discuss a new binary obfuscation method based on reassemble. The binary reassembling refers to the process of disassembling an executable binaries into assembly code and assemble it back to a correct binary. We make binary obfuscation in this process because it can avoid many problems and have better protection than other obfuscation methods. We designed two obfuscating schemes including instruction substitution and control flow confusion. The resulting code is still a correct program, but it has more complex instruction execution sequence and sophisticated control flow graph. According to the experiment results, the obfuscated program has more smaller file size but it execute more slowly than the original program.

Multiresolutional Hierarchical Bayesian NMF for Detailed Audio Analysis of Music Performances

In this paper, we discuss a method for a music performance detail analysis using multiresolution analysis allowing simultaneous estimation of pitch, precise onset, duration and intensity from polyphonic audio. The motivation is to obtain information that is detailed enough to develop a performance model of a human player. Characteristics of human performance can be observed as local and global tempo changes, sound intensity (volume or velocity in a MIDI), and articulations like slur and staccato. Estimation and extraction of such features from a musical audio signal in detail is useful for music information retrieval systems, automatic transcription systems, as well as automatic performance systems to train the relationship between music features and player performance. Our proposed system is based on non-negative matrix factorization (NMF) using hierarchical Bayesian inference, which is modeling harmonic and nonharmonic structures, note durations, intensities, and onset information stochastically. The estimation process comprises two steps. In the first step, variational Bayesian inference and a Gaussian mixture model is used to roughly estimate pitch onset, intensity and duration. These values are used as a prior for the second more detailed step, in which time resolution is doubled and the estimation is repeated to refine the results. The evaluation results show that the our proposed multiresolution Bayesian model can estimate more precise onset times and durations than our non-multiresolution Bayesian model.
Measuring Researcher Relatedness with Changes in Their Research Interests

Relevant researcher recommendation is important for finding potential research collaborators, and several existing methods measure researcher relatedness based on their research interests. Our previous works represented a researcher with a single multidimensional topic vector calculated from the researcher's publications, ignoring the publication dates. On the other hand, recent studies on information recommendation have shown the effectiveness of modeling changes in user preferences over time. Thus, this paper proposes a new representation of researchers, which consists of yearly topic vectors. To measure the relatedness between researchers, we calculate the similarity between two sequences of topic vectors using Dynamic Time Warping. An experimental example visualizes topic transitions of a target researcher and demonstrates that the proposed method can effectively find researchers whose topic transitions are similar over time, when compared to the conventional method.
Discovering Frequent Movement Paths From Taxi Trajectory Data Using Spatially Embedded Networks and Association Rules

In view of the complex traffic flows, spatial interactions within a city exhibit the properties of dynamics, connectivity, and repeatability. This paper aims at mining spatial–temporal movement patterns from massive taxi trajectory data for discovering the inherent travel flow information within the urban system. Similar to the role of ocean circulation in a marine system, identifying the frequent paths and cycles of the travel flows within a city would be critical for understanding the principles behind the travel flow surfaces. Thus, we propose a multi-level method for the discovery of movement paths by incorporating the techniques of network analysis and association rules. Specifically, the proposed method begins by constructing a directed network on the subdivision of the study region, in which the node with geolocation represents the corresponding cell and the edge with weight represents the travel flow between neighboring cells. The method then adopts an extended label propagation clustering algorithm to identify frequent paths and cycles on the flow network within a specific time interval. Finally, to extract frequent paths during the whole time period, we also develop an association rules mining algorithm by modeling the edges as items and the paths in each time span as transactions. Experiment results demonstrate that our framework is able to effectively mine movement patterns in taxi trajectory data. Our results are expected to provide an avenue for further research, such as transportation planning and urban structure analysis.
Protein Degradation Assays in Arabidopsis Protoplasts

[Abstract] Plant transformation and exogenous protein expression is essential for molecular biology and biotechnology. Current approaches of stable plant transformation might be problematic and very time-consuming. Because of this, transient expression in protoplasts has become valuable alternative, being less cost and time-effective at the same time. Excellent for eukaryotic proteins, representing a natural cell habitat, protoplast isolation is widely used in protein interaction visualization techniques, like BiFC (Bimolecular fluorescence complementation) and FRET (Förster resonance energy transfer). In this protocol we present a another use of Arabidopsis protoplast in protein degradation assay, proving its high versatility as a tool in proteomics.

Food of plant origin: production methods and microbiological hazards linked to food‐borne disease. Reference: CFT/EFSA/BIOHAZ/2012/01 Lot 1 (Food of plant origin with high water content such as fruits, vegetables, juices and herbs)

Food-borne diseases caused by food of non-animal origin (FoNAO) contaminated with pathogenic bacteria, viruses and parasites are a major health concern worldwide. The present study was set up as an extensive literature review aimed at evaluating biological hazards associated with FoNAO with high water content. Data were extracted from 432 publications to identify the most critical FoNAO/pathogen combinations. The number and severity of outbreaks of disease provided the basis for a primary evaluation, and qualitative criteria relating to pathogen prevalence, food/pathogen interaction, and the production of FoNAO items were used for defining three priority groups. Highest priority levels worldwide were defined for leafy green vegetables contaminated with pathogenic E. coli. Salmonella on/in leafy greens and tomatoes were also most highly graded. While strawberries and raspberries infected with Norovirus were graded priority one within the EU, cantaloupe melon and tropical fruit contaminated with Salmonella were included in the priority one combinations for non-EU countries. Level two and level three priority groups differed for EU and non-EU countries, including lettuce/Norovirus, basil/Salmonella spp. , semidried tomatoes/Hepatitis A virus, grated carrots/Yersinia pseudotuberculosis for EU and lettuce/Norovirus, spinach/pathogenic E.coli, cantaloupe melon/Listeria monocytogenes, and Hepatitis A virus combined with unpasteurized orange juice and green onion for non-EU countries, respectively. The study provides an extensive scientific database that will be instrumental in the conceptualization of specific measures for preventing and efficiently controlling outbreaks of disease linked to FoNAO. © AIT Austrian Institute of Technology GmbH
Integrating Winter Annual Cereal Rye or Triticale into a Corn Forage Biofuel Production System

ABSTRACT Integrating cover crops into the corn (Zea mays L.) forage-production system could enhance growers’ profitability and improve ecosystem services. Field plots were established at two locations in Michigan during 2012--2014 to evaluate ethanol production, estimate carbon and energy balance, and the economics of corn forage plus cover crop, cropping systems. In the 2012--2013 crop cycle, which was characterized by a summer drought, the cereal rye (Secale cereale L.), and triticale (Triticale hexaploide Lart.), winter annual cover crops increased cropping system biomass yield by 44%, and total ethanol yield by 28% relative to the no-cover control. During the 2012--2013 cycle, cover crops provided sufficient biomass (6.5 and 8.1 Mg ha−1, respectively, for cereal rye and triticale) to result in a profitable harvest as a biofuel feedstock. However, following a harsh winter, such as that experienced in the 2013--2014 cycle, cover crop yield (1.6 and 1.2 Mg ha−1, respectively, for cereal rye and triticale) was compromised to the point that harvest was not economically justified. Incorporating cover crops into a corn forage cropping system increased total biomass and potential biofuel yield and generated a very favorable net ecosystem carbon and energy balance.
Production of human papillomavirus of he ".nfectious and modulation .t 1 program m eplthehal raft cultures

Human papillomaviruses trophic for anogenital epithelia cause benign warts, and certain genotypes are closely associated with cervical neoplasia. By using our modifications of the epithelial raft culture system, we were able to recapitulate and modulate the infectious program of a papillomavirus in vitro for the first time. Small pieces of a condyloma containing human papillomavirus type 11 were explanted onto a dermal equivalent consisting of a collagen matrix with fibroblasts and were cultured at the medium-air interface. The infected stem cells proliferated rapidly across the matrix, stratified, and differentiated, as judged by histology. The results correlated with the state of epithelial differentiation, which, in turn, was dependent on the type of fibroblast in the matrix. Under conditions where the epithelial outgrowth underwent terminal differentiation, the entire productive program took place, leading to virion assembly. In contrast, using an alternative condition where the outgrowth failed to achieve terminal differentiation, only the E-region RNAs from the E1 promoter accumulated to any appreciable extent. The proliferating cell nuclear antigen was induced in the differentiated suprabasal cells in the productive cyst growth, which also exhibited high copy viral DNA and abundant E6--E7 RNAs. Comparable cells in the nonproductive cyst outgrowth were negative for all three. These results suggest that the E6 and E7 proteins may play a role in establishing a cellular environment conducive to vegetative viral replication. The culture conditions described should be useful for genetic analysis of this family of important human pathogens and for testing potential pharmacological agents.
