Illumination Invariant Dense Image Matching based on Sparse Features

In this paper we propose an algorithm for dense depth estimation based on a cost function, which is robust against changes in illumination. For this purpose, we utilize census transformation and Phase Congruency. The process of cost computation is supported by a triangle-based depth prediction approach using a set of matched feature points. These points can reliably be detected even under drastic changes in illumination. We demonstrate the performance of our approach on the challenging KITTI stereo dataset and a set of images with simulated changes. The results show that the concept achieves state-of-the-art on images with similar illumination conditions and is robust against changed conditions.
1‐(3‐Biaryloxy‐2‐oxopropyl)indole‐5‐carboxylic Acids and Related Compounds as Dual Inhibitors of Human Cytosolic Phospholipase A2α and Fatty Acid Amide Hydrolase

Cytosolic phospholipase A2α (cPLA2α) and fatty acid amide hydrolase (FAAH) are enzymes that have emerged as attractive targets for the development of analgesic and anti‐inflammatory drugs. We recently reported that 1‐[3‐(4‐octylphenoxy)‐2‐ oxopropyl]indole‐5‐carboxylic acid (5) is a dual inhibitor of cPLA2α and FAAH. Structure–activity relationship studies revealed that substituents at the indole 3‐ and 5‐positions and replacement of the indole scaffold of this compound by other heterocycles strongly influences the inhibitory potency against cPLA2α and FAAH, respectively. Herein we report the effect of variation of the 4‐octyl residue of 5 and an exchange of its carboxylic acid moiety by some bioisosteric functional groups. Several of the compounds assayed were favorably active against both enzymes, and could therefore represent agents with improved analgesic and anti‐inflammatory qualities in comparison with selective cPLA2α and FAAH inhibitors.
Menstrual and hormonal alterations in juvenile systemic lupus erythematosus

Menstrual cycles of 30 patients with juvenile systemic lupus erythematosus (JSLE) were compared with 30 age-matched controls. The mean age of patients with JSLE and controls was similar (17.4 ± 3.2 vs 17.06 ± 2.08 years, P = 0.66). The mean menarche age was higher in JSLE than controls (13.13 ± 1.4 vs 11.56 ± 1.5 years, P = 0.0008). On the contrary, the mean maternal menarche age was similar in both groups (P = 0.62). Menstrual abnormalities and longer length cycles were more frequently observed in JSLE than controls (63% vs 10%, P = 0.0001; 23% vs 0%, P = 0.0105, respectively). The median of follicle stimulating hormone was significantly higher in patients with JSLE compared with controls (4.6 vs 3.4 IU/L, P = 0.0207), and the median of progesterone was lower (32.5 vs 70 ng/mL, P = 0.0033). The median of luteinizing hormone was lower in patients with JSLE with menstrual abnormalities versus normal cycles (2.9 vs 5.5 IU/L, P = 0.019) and both had a high percentage of decreased progesterone levels (63% vs 73%, P = 0.70). Our findings support the notion that menstrual disturbances are frequent and may be associated with pituitary dysfunction leading to a decreased progesterone production. We also reported that in spite of premature ovarian failure being a rare event in JSLE the follicular reserve seems to be low regardless of intravenous cyclophosphamide treatment.
On self-optimization of the random access procedure in 3G Long Term Evolution

Operationally efficient radio networks typically feature a high degree of self-organization. This means less planning efforts and manual intervention, and a potential for better radio resource utilization when network elements adapts its operation to the observed local conditions. The focus in this paper is self-optimization of the random access channel (RACH) in the 3G Long Term Evolution (LTE). A comprehensive tutorial about the RACH procedure is provided to span the complexity of the self-optimization. Moreover, the paper addresses RACH key performance metrics and appropriate modeling of the various steps and components of the procedure. Finally, some coupling between parameters and key performance metrics as well as self-optimization examples are presented together with a feasibility discussion. The main ambition with this workshop paper is to present and define a relevant set of self-optimization problems, rather than to provide a complete solution.
Condition Monitoring and Vibration Analysis of Boiler Feed Pump

Condition Monitoring is an advanced and very useful tool of predictive maintenance techniques. It has made good progress in recent years in identifying many types of deterioration in plant machinery, so that pro-active maintenance can be performed, improving overall plant productivity. There is a wide variety of condition monitoring techniques currently in use for the diagnosis and prediction of machinery faults, but little attention has been paid to the occurrence and detection of vibration analysis of rotating equipments The application of computers and electronic measuring and detecting system has provided a new improvement for condition monitoring and has a particular relevance for plant engineers in utilities and service departments. It eliminates unnecessary opening of equipment with considerable savings in personnel resources. This paper aims at the implementation of condition based maintenance on BOILER FEED pump critical Machine used in the thermal plant, by adopting Vibration spectrum analysis which is a predictive maintenance technology. For the BOILER FEED pump the vibration readings show that values are more than normal readings. Spectrum analysis was done on readings and found that mass unbalance in vanes. It was corrected based on phase analysis and vibration readings were observed after modification which gives the values with in normal range. It eliminates unnecessary opening of equipment with considerable savings in personnel resources.

WEB DATA EXTRACTION AND ESTABLISHMENT OF A META SOCIAL NETWORK

Currently, Internet is considered as the main information source, this information is not directly exploitable by computers, that’s what make the importance of the problem of information extraction from the web. Our article is about the “gene/clone” approach that is an approach for extracting information from the web, it consist on generating a gene from a set of examples instances entered by the user . The gene designates the smallest repetitive structure containing all values of examples instances. The search of the clones of gene allows to retrieve the other instances of the relationship to extract. The objective of this paper is to improve the accuracy of the Gene / Clone approach, so we propose new concepts namely the structural prefix and structural suffix . The use of structural prefixes and structural suffixes allows to increase the accuracy of the gene and so improve the accuracy of data extraction . Also in this article the, we give an evaluation of these two methods on several data sources . At the end of the article, we propose a direct use of our approach, in fact, we have developed an application for extracting and gathering data from several social networks in order to generate a meta social network.
Reference Scope Identification for Citances Using Convolutional Neural Networks

In the task of summarization of a scientific paper, a lot of information stands to be gained about a reference paper, from the papers that cite it. Automatically generating the reference scope (the span of cited text) in a reference paper, corresponding to citances (sentences in the citing papers that cite it) has great significance in preparing a structured sum-mary of the reference paper. We treat this task as a binary classification problem, by extracting feature vectors from pairs of citances and reference sentences. These features are lexical, corpus-based, surface and knowledge-based. We extend the current feature set employed for reference-citance pair identification in the current state-of-the-art system. Using these features, we present a novel classification approach for this task, that employs a deep Convolu-tional Neural Network along with two boosting ensemble algorithms. We outperform the existing state-of-the-art for distinguishing between cited spans and non-cited spans of text in the reference paper.
1-Methylcyclopropene Effects on Field-Grown Cotton: Morphological Characteristics and Yield

Upland cotton (Gossypium hirsutum L.) is an important socioeconomic crop throughout most of the southern U.S. In Texas, cotton is the lead cash crop and its productivity is often limited by abiotic stress events such as drought and elevated ambient temperatures. The objective of this study was to assess the effects of 1-methylcyclopropene (1-MCP) applications triggered by canopy temperature and forecasted ambient temperatures on field-grown cotton plants. Yield and crop morphological responses to 1-MCP applications were investigated in field studies conducted during the summers of 2012 to 2014 at the Texas A&M University Field Laboratory in Burleson County, TX. Positive effects of 1-MCP were found for fruit retention in 2013 and 2014 for both irrigated and dryland studies; however, a negative impact was found in the 2012 irrigated study. By harvest, 1-MCP applications had no effect on final cotton yield or fiber quality parameters. Applications of 1-MCP affected some morphological characteristics of cotton plants; however, it did not improve crop yield.
Impact of Inputs Costs on Farm Profitability: An Evaluation of Pearl Millet Production in North-Western Nigeria

The current study was carried out to estimate cost, returns and the profitability level of pearl millet production in north-western Nigeria. The study made use of primary data collected from a cross section of 430 pearl millet farmers and analysed using descriptive statistics, budgetary technique, profitability ratio, and Ordinary Least Square regression analysis. The study reveals that an average gross margin and net farm income across all the sampled pearl millet farms were $233.89 and $200.89 respectively, while average total cost was $ 229.35 per cultivation season. The profitability index, rate of return on investment and capital turnover were $ 0.43, 0.77 and $ 1.77, respectively. This is an indication that pearl millet production is profitable in the study area. It is also established that the coefficients of costs of renting land, fertilizer, labour, seed, agrochemicals and price of pearl millet output have significantly impact on gross margin of pearl millet production. Based on the above findings, the study concludes that profit level of the pearl millet can be significantly increased with policies that guarantee better farmer price and lower inputs costs.
A Compact and Accurate FPGA Based Nonisotropic Fading Channel Simulator

A novel design and implementation technique for generating Rayleigh fading variates is presented in this paper. An FPGA implementation of the new baseband fading simulator utilizes only 6.8% of the configurable slices and generates 10 million statistically accurate samples per second. Increasing the output sample rate to up to 300 million samples per second is possible with a slight increase in the resource utilization. A wide variety of channel characteristics and sample rates can be achieved with parameterizing the new baseband channel simulator.
Short upstream region drives dynamic expression of hypoxia‐inducible factor 1α during Xenopus development

Hypoxia‐inducible factor 1α (HIF‐1α) plays a central role in regulating oxygen‐dependent gene expression and is involved in a range of pathways implicated in cellular survival, proliferation, and development. While the posttranslational regulation of HIF‐1α is well characterized, the relative importance of its control at the transcriptional level during development remains less clear. Although the mouse and human promoter regions have been analyzed in vitro, to date, there has been no in vivo analysis of any vertebrate HIF‐1α promoter. To investigate the transcriptional regulation of HIF‐1α during development of the amphibian Xenopus laevis, we have described the gene's expression pattern and isolated the xHIF‐1α upstream regulatory regions. We show xHIF‐1α mRNA to be constitutively expressed at low levels throughout embryogenesis, but with significant up‐regulation during gastrula stages, and subsequently, in specific regions of the central nervous system and axial tissues. Our functional analysis using a series of truncated xHIF‐1α promoter constructs demonstrates that a 173‐bp region of the proximal promoter, which is 100% conserved among five allelic variants, is sufficient to drive correct expression in transgenic embryos. Although these results are corroborated by a parallel set of in vitro transfection experiments in a Xenopus cell line, some key differences suggest the importance of using transgenic methods in conjunction with in vitro assays.

Human striatum is differentially activated by delayed, omitted, and immediate registering feedback

The temporal contingency of feedback during conversations is an essential requirement of a successful dialog. In the current study, we investigated the effects of delayed and omitted registering feedback on fMRI activation and compared both unexpected conditions to immediate feedback. In the majority of trials of an auditory task, participants received an immediate visual feedback which merely indicated that a button press was registered but not whether the response was correct or not. In a minority of trials, and thus unexpectedly, the feedback was omitted, or delayed by 500 ms. The results reveal a response hierarchy of activation strength in the dorsal striatum and the substantia nigra: the response to the delayed feedback was larger compared to immediate feedback and immediate feedback showed a larger activation compared to the omission of feedback. This suggests that brain regions typically involved in reward processing are also activated by non-rewarding, registering feedback. Furthermore, the comparison with immediate feedback revealed that both omitted and delayed feedback significantly modulated activity in a network of brain regions that reflects attentional demand and adjustments in cognitive and action control, i.e., the posterior medial frontal cortex (pMFC), right dorsolateral prefrontal cortex (dlPFC), bilateral anterior insula (aI), inferior frontal gyrus (Gfi), and inferior parietal lobe (Lpi). This finding emphasizes the importance of immediate feedback in human–computer interaction, as the effects of delayed feedback on brain activity in the described network seem to be similar to that of omitted feedback.

The distribution pattern of soil macrofauna at the forest-steppe ecotone of the southernmost boreal forest (Eastern Kazakhstan).

We determined the activity density, population density and family-level diversity of surface-active and soil-inhabiting macrofauna in the forest interior, forest edge and steppe habitats in eastern Kazakhstan, and asked whether there were differences in their assemblages that reflected the soil properties and habitat disturbance (livestock grazing). Overall abundances of the macroarthropod assemblages were similar in most study sites, being significantly different for only some groups, such as Araneae, Chilopoda, Diplopoda, Scarabaeidae and Silphidae. The population densities of soil-inhabiting animals were relatively higher in the forest interior than in the forest edge and steppe. The soil water content has little influence on the total activity density of surface-active macroarthropods or on the population density of soil-inhabiting macrofauna, but we observed significant correlations between soil water content and the activity density of a few individual groups of surface-active arthropods (Carabidae, Staphylinidae, Scarabaeidae, Silphidae). Similar relationships were observed between soil water content and the population density of some soil-inhabiting groups of macrofauna (Araneae, Chilopoda, Curculionidae). The overall activity density of surface-active macroarthropods showed a slight negative correlation with soil bulk density, but significant relationships were found for only some groups (Staphylinidae, Silphidae, Scarabaeidae). The soil bulk density showed no significant relationship with the population density of any group of the soil-inhabiting macrofauna. We could not prove an influence of grazing intensity on the soil macrofauna, because differences in grazing intensity between study sites were not significant.
Human Adipose-Derived Mesenchymal Progenitor Cells Engraft into Rabbit Articular Cartilage

Mesenchymal stem cells (MSCs) are known to have the potential for articular cartilage regeneration, and are suggested for the treatment of osteoarthritis (OA). Here, we investigated whether intra-articular injection of xenogeneic human adipose-derived mesenchymal progenitor cells (haMPCs) promoted articular cartilage repair in rabbit OA model and engrafted into rabbit articular cartilage. The haMPCs were cultured in vitro, and phenotypes and differentiation characteristics of cells were evaluated. OA was induced surgically by anterior cruciate ligament transection (ACLT) and medical meniscectomy of knee joints. At six weeks following surgery, hyaluronic acid (HA) or haMPCs was injected into the knee joints, the contralateral knee served as normal control. All animals were sacrificed at the 16th week post-surgery. Assessments were carried out by macroscopic examination, hematoxylin/eosin (HE) and Safranin-O/Fast green stainings and immunohistochemistry. The data showed that haMPC treatment promoted cartilage repair. Signals of human mitochondrial can be directly detected in haMPC treated cartilage. The haMPCs expressed human leukocyte antigen I (HLA-I) but not HLA-II-DR in vivo. These results suggest that intra-articular injection of haMPCs promotes regeneration of articular cartilage in rabbit OA model, and support the notion that MPCs are transplantable between HLA-incompatible individuals.
Thermographic measurements of planar inductors

Heating of circuits in electronics is an important design and operational aspect. Furthermore, there is an increasing need to check and evaluate temperature measurements acquired with the use of thermographic equipment. In other works, surface temperature distributions were captured and presented in an attempt to visualize the way heat is dissipated in the case of an integrated inductor. The aim of this paper is to interpret the thermograms captured with an infrared cooled image system during temperature measurements of Printed Circuit Board inductors.
Synthesis of Titanium Dioxide Nanotubes from Titanium Dioxide Nanoparticles and Their Photocatalytic Activities

Titanium dioxide nanotubes (TiNT) were prepared by treating titanium dioxide (TiO2) nanoparticles with hot NaOH solution. The TiO2 nanoparticles (anatase) used in this work were precipitated TiO2, SiO2-TiO2 and commercialgrade (C02 and P25) nanoparticles. The diameters of the obtained nanotubes were nearly the same (~5-16 nm), regardless of the type of the starting nanoparticles. The photocatalytic actitivity of TiO2 samples were dependent on their crystallinity, defects on the surface, photon absorptivity, particle size and surface area being exposed to UV radiation. TiNT had higher surface areas and more surface defects than the starting particles but the crystallinity, photon absorptivity and photocatalytic activities of the former were lower than those of the latter. The precipitated TiO2 nanoparticles showed highest photocatalytic activity in KI oxidation, while TiNT from SiO2-TiO2 particles showed lowest activity. For an equal amount of absorbed photon, SiO2-TiO2 particles showed highest photon-to-product conversion efficiency.
