Ridge Matching Based on Maximal Correlation in Transform Space

Image matching, a common technique in Computer Vision to identify objects, persons, locations, etc., is widely used in both military and civilian applications. For common image matching algorithms, results may vary when the raw images are captured under different lighting conditions. To reduce the unwanted influence from ambient lighting, we propose a novel method to match images that contain ridge features. The new method uses an established ridge detection algorithm to reduce raw images to sets of ridge points, each point defined by its orientation and location. To perform ridge matching, we find the pair-wise transform between every ridge point from one image and every ridge point from another. The result is a point cloud in transform space. The correlation between two sets of ridge point is equivalent to the density of the point cloud, computed by convolving the point cloud with a blurring kernel. The best match is found as the location in transform space at which the correlation reaches global maximum. We tested the new method on two image pairs; the first image pair contained artificial ridge features and the second pair was sampled from a high resolution image of the human palm. Both tests returned accurate results.
CPY3A4-Mediated Lopinavir Bioactivation and Its Inhibition by Ritonavir

The combination of lopinavir (LPV) and ritonavir (RTV) is one of the preferred regimens for the treatment of HIV infection with confirmed efficacy and relatively low toxicity. LPV alone suffers the poor bioavailability due to its rapid and extensive metabolism. RTV boosts the plasma concentration of LPV by suppressing its metabolism and thus increasing LPV efficacy. In the current study, we found that RTV also inhibits LPV bioactivation. LPV bioactivation was investigated in human liver microsomes and cDNA-expressed human cytochromes P450. Twelve GSH-trapped reactive metabolites of LPV were identified by using a metabolomic approach. Semicarbazide-trapped reactive metabolites of LPV were also detected. RTV effectively suppressed all pathways of LPV bioactivation via CYP3A4 inhibition. Our data together with previous reports suggest that LPV plus RTV is an ideal combination because RTV not only boosts LPV plasma concentration, but it decreases LPV bioactivation.
CoCo 2017 Participant : CSÎ ho 0 . 3 ∗

Higher-order rewriting combines first-order rewriting with notions and concepts from λcalculus, resulting in rewrite systems with higher-order functions and bound variables. CSÎ ho is a tool for automatically proving confluence of such higher-order systems, specifically pattern rewrite systems (PRSs) as introduced by Nipkow [3, 6]. The restriction to pattern left-hand sides is essential for obtaining decidability of unification and thus makes it possible to compute critical pairs. To this end CSÎ ho implements a version of Nipkow’s algorithm for higher-order pattern unification [7]. CSÎ ho is an extension of CSI, a powerful confluence prover for first-order term rewrite systems. The tool and a web interface are available from
Nonstandard natural number systems and nonstandard models

Abstract It is known (see [1, 3.1.5]) that the order type of the nonstandard natural number system *N has the form ω + (ω* + ω) θ, where θ is a dense order type without first or last element and ω is the order type of N. Concerning this, Zakon [2] examined *N more closely and investigated the nonstandard real number system *R, as an ordered set, as an additive group and as a uniform space. He raised five questions which remained unsolved. These questions are concerned with the cofinality and coinitiality of θ (which depend on the underlying nonstandard universe *U). In this paper, we shall treat nonstandard models where the cofinality and coinitiality of θ coincide with some appropriated cardinals. Using these nonstandard models, we shall give answers to three of these questions and partial answers to the other to questions in [2].
Comparing Students ’ Expectations with the Students ’ Perceptions of Service Quality Provided in Open and Distance Learning Institutions in Zimbabwe ’ s Mashonaland East Region Trust Nyenya

This quantitative survey was conducted to compare students’ service expectations against perceptions of level of satisfaction of the services delivered in an open and distance learning (ODL) institution like the Zimbabwe Open University (ZOU). The adjusted SERVQUAL scale as conceived by [22] was adopted to determine the gap and direction of the service quality delivered at ZOU. The study focused on the expectations and perceptions of ODL students in Mashonaland East Region, which has an enrollment of 360 active students. A random sample of 86 (22%) of the total enrollment responded to the instrument on the last tutorial of 2014. The research findings indicated that ODL institutions need to pay attention to all the dimensions of service quality since there is a negative gap in all the dimensions. ODL institutions should obtain information on the best interests and needs of its students and focus on satisfying them [Empathy]. ODL materials should be well bound and up to date [Tangibility], students should feel safe in conducting business with staff and academics [Security], excellent ODL institutions keep up to date students’ records [Reliability], and academics and staff should have the knowledge to answer students’ questions [Security]. While there is a gap between performance and expectation, statistically, students are satisfied with the overall performance of the institution based on the correlation coefficient [0.99] calculated. The research recommends that the institution invest in training academic staff on customer care. The institution should also invest in finding out customer needs and focus on satisfying the identified needs. The institution should adhere to the procedures for record generation and keeping in line with the university standards. The university should further invest in modules and campus aesthetics as these have a bearing on enrollment and quality of material learnt.
OF KNEE TOTAL ARTHROPLASTY IN TWO STEPS : THE VALUE OF CULTURE OBTAINED THROUGH ARTHROSCOPIC BIOPSY

226 Trabalho recebido em 10/03/06 aprovado em 25/05/06 INTRODUÇÃO Osteoartrose é a doença articular mais prevalente em adultos idosos, ocorrendo devido ao processo degenerativo da cartilagem articular. A artroplastia de joelho é uma técnica cirúrgica para o tratamento da osteoartrose avançada, sendo cada vez mais utilizada devido aos bons resultados no alívio da dor e no restabelecimento da função. Já no meio do século XIX, tentativas de artroplastia foram feitas como a de ressecção realizada por Fergusson em 1861 e a de interposição de partes moles preconizada por Verneil em 1863. Na década de 40 iniciaram-se as técnicas de substituição de superfície e, com o desenvolvimento de tecnologia adequada, surgiram as próteses tricompartimentais de joelho que hoje são utilizadas, sendo a primeira desenvolvida por Freeman, culminando nos modelos atuais(1). Como toda cirurgia, a artroplastia total de joelho está sujeita a complicações, dentre as quais podemos citar: fenômenos tromboembólicos, complicações atingindo a articulação femoro patelar, lesões neurovasculares, fraturas periprotéticas, soltura dos componentes implantados e a infecção, muito temida pelo cirurgião ortopédico. As infecções nas artroplastias totais de joelho podem ser divididas em superficiais e profundas. A incidência de infecções profundas em artroplastias primárias varia de 0,5% a 5%(2). Quanto ao tratamento da infecção existem vários tipos de procedimentos, sendo eles: antibioticoterapia, limpeza cirúrgica com manutenção do ARTIGO DE REVISÃO
PEDESTRIAN AND OBJECT DETECTION USING LEARNED CONVOLUTIONAL FILTERS

Object detection is still a very active field in Computer Vision. Until now, part based models proved to be one of the most interesting and successful approaches in object and pedestrian detection. The method applies a machine learning approach not to the input images themselves, but to histograms of gradients. However, its performances are still limited when compared to what humans can do. The purpose of the present paper is to show that sparse representations can be successfully used in object detection. The main advantage of using this method is related to the possibility of learning only those filters that are able to express the most frequent patterns that appear in the analyzed images. The experiments are carried out on two widely used datasets, namely VOC2007 and INRIA Person.
sediments Quantitative analysis of seismogenic shear-induced turbulence in lake

Spectacular deformations observed in lake sediments in an earthquake prone region (Lisan Formation, pre–Dead Sea lake) appear in phases of laminar, moderate folds, billow-like asymmetric folds, coherent vortices, and turbulent chaotic structures. Power spectral analysis of the deformation indicates that the geometry robustly obeys a power-law of –1.89, similar to the measured value of Kelvin-Helmholtz (KH) turbulence in other environments. Numerical simulations are performed using properties of the layer materials based on measurements of the modern Dead Sea sediments, which are a reasonable analogue of Lake Lisan. The simulations show that for a given induced shear, the smaller the thickness of the layers, the greater is the turbulent deformation. This is due to the fact that although the effective viscosity increases (the Reynolds number decreases) the bulk Richardson number becomes smaller with decrease in the layer thickness. The latter represents the ratio between the gravitational potential energy of the stably stratifi ed sediments and the shear energy generated by the earthquake. Therefore, for thin layers, the shear energy density is larger and the KH instability mechanism becomes more effi cient. The peak ground acceleration (PGA) is related to the seismogenic shear established during the earthquake. Hence, a link is made between the observed thickness and geometry of a deformed layer with its causative earthquake’s PGA. Figure 1.

Microbeam radiation therapy: a review

The radiation effects in tissue depend not only on dose but also on volume exposed, for example, the smaller the volume, the greater the tolerance. Microbeam radiation therapy (MRT), which exploits this effect, can only be achieved with synchrotron X-rays owing to their extraordinarily slight divergence. MRT research over the past 20 years has yielded many results from preclinical trials based on different animal models, including mice, rats, piglets and rabbits. Typically, targets are exposed to multiple quasi-parallel slices of radiation some tens of micrometres wide with on-centre separations of several hundred micrometres. The microplanar beams are produced by a multi-slit collimator, which cuts horizontally microscopic beam sectors from a wiggler-generated fan beam. Peak entrance doses of several hundreds of Gy are surprisingly well tolerated by normal tissues and at the same time show a preferential damage of malignant tumour tissues.
Pantoea agglomerans SWg 2 colonizes mulberry tissues , promotes disease protection and seedling growth

Mulberry bacterial blight caused by Pseudomonas syringae pv. mori, is one of the most serious diseases on mulberry (Morus alba L.), and threatens sericulture development. An endophytic Pantoea agglomerans SWg2 (referred to as SWg2), originally isolated from roots of healthy mulberry, is extremely inhibitory activity to P. syringae. Greenhouse tests were first conducted to examine the biological control properties of SWg2. A suspension of SWg2, introduced to the host plant, significantly reduced disease symptoms caused by P. syringae. Likewise, when a suspension of SWg2 was sprayed onto plantlets 2 days before inoculation with P. syringae, its disease control efficacy was up to 65.6% even after inoculation with P. syringae 18 days later. Interestingly, the control effect of the traditional agrochemical streptomycin was just 33.2% at 18 days post inoculation (DPI), although it was 55.6% at 9 DPI. Furthermore, SWg2 promoted the growth of mulberry seedlings. The immersion of 10 CFU mL suspension of SWg2 had the most distinctive growth-promoting role since the seed germination rate and radicle length development were enhanced up to 100% and 144.2%, respectively. Based on the green fluorescent protein (GFP) labeling technique and a re-isolation method, it was determined that the SWg2 strain colonized and spread in mulberry seedlings. The bacteria entered seedlings through the areas of emergence of root hairs and cracks in the rhizodermis. Eventually these cells spread to other tissues of the plant with colonization occurring mainly in the intercellular spaces. Furthermore, the GFP-tagged SWg2 strain could be detected in stems and leaves, but the quantity was smaller than that in roots. There appears to be no outward negative effects of SWg2 on treated plants and silkworms feed on them in a normal manner. This work indicates that P. agglomerans SWg2 possesses the biological potential to provide protection of its host against the pathogen of mulberry bacterial blight will at the same time promoting the growth and vigor of the host plant.
EyeLad: Remote Eye Tracking Image Labeling Tool - Supportive Eye, Eyelid and Pupil Labeling Tool for Remote Eye Tracking Videos

: Ground truth data is an important prerequisite for the development and evaluation of many algorithms in the area of computer vision, especially when these are based on convolutional neural networks or other machine learning approaches that unfold their power mostly by supervised learning. This learning relies on ground truth data, which is laborious, tedious, and error prone for humans to generate. In this paper, we contribute a labeling tool (EyeLad) speciﬁcally designed for remote eye-tracking data to enable researchers to leverage machine learning based approaches in this ﬁeld, which is of great interest for the automotive, medical, and human-computer interaction applications. The tool is multi platform and supports a variety of state-of-the-art detection and tracking algorithms, including eye detection, pupil detection, and eyelid coarse positioning. Furthermore, the tool provides six types of point-wise tracking to automatically track the labeled points. The software is openly and freely available at: www.ti. uni-tuebingen.de/perception
Isolation of Azospirillum lipoferum 4T Tn5 Mutants Affected in Melanization and Laccase Activity

Azospirillum lipoferum 4T has original properties such as nonmotility, melanin synthesis, and laccase activity. Following random Tn5 mutagenesis in A. lipoferum 4T, we obtained 10 mutants which were affected in melanization and laccase activity. The class 1 mutants, with intermediate levels of laccase activity, showed some coloration; the class 2 mutants, which were completely negative for laccase activity, were also colorless. The Tn5 localization on the chromosome or on the cryptic 300-MDa plasmid of A. lipoferum 4T was proven by hybridization for all class 1 mutants or for most class 2 mutants, respectively.
Dietary patterns and social structures in medieval Sigtuna , Sweden , as reflected in stable isotope values in human skeletal remains q

Stable isotopes (d13C, d15N) have been studied in human burials from the medieval town Sigtuna in Sweden. Dietary patterns of 80 adult individuals were analyzed on three cemeteries representing the phases of establishment, prosperity and decline of the town. All analyzed individuals were radiocarbon dated. One of the cemeteries, Church 1, represents a population of higher social status than those at the other two cemeteries. The d13C values are homogenous and showed that the protein intake was mainly of terrestrial origin in the whole population. d15N values varies more and they may indicate a higher input of vegetables in the diet at one of the cemeteries, the Nunnan block. Already in the initial phases of Sigtuna a social hierarchy had been established which is reflected in dietary patterns. Apparently more animal protein was consumed among the high status population of the town. Furthermore, differences in dietary patterns between the sexes were noted. In all phases the females show more clustered values indicating a more homogeneous diet than that of the males. 2009 Elsevier Ltd. All rights reserved.
Recommendation Based on Heterogeneous Graph ?

Digital libraries suffer from the overload problem, which makes the researchers have to spend much time to find relevant papers. Fortunately, recommender system can help to find some relevant papers for researchers automatically according to their browsed papers. Previous paper recommendation methods are either citation-based or contentbased. In this paper, we propose a novel recommendation method with a heterogeneous graph in which both citation and content knowledge are included. In detail, a heterogeneous graph is constructed to represent both citation and content information within papers. Then, we apply a graph-based similarity learning algorithm to perform our paper recommendation task. Finally, we evaluate our proposed approach on the ACL Anthology Network data set and conduct an extensive comparison with other recommender approaches. The experimental results demonstrate that our approach outperforms traditional methods.
Coupling reduction between two elements of array antenna using U-shaped defected ground structure

This paper presents the U-shaped defected ground structure (DGS) which is incorporated into the groundplane of array antenna to reduce the coupling between antenna elements. The array antenna is constructed of two layers of flame resistant (FR) 4 epoxy dielectric substrate with the thickness of each layer of 1.6mm. The U-shaped DGS is placed at the bottom side of second layer between two elements of array antenna located on the top side of first layer. A proximity feeding technique of microstrip line applied to feed each antenna element is positioned on the top side of second layer. By reducing the coupling which is generated due to the input power at both feeding ports, the radiation characteristics of array antenna can be improved. To demonstrate the feasibility of U-shaped DGS in coupling reduction, an array antenna without DGS is also investigated. The characterization results have verified that the U-shaped DGS is applicable to reduced the coupling at the resonant frequency of 2.38GHz up to 2dB and 0.88dB for simulation and measurement, respectively.
Senna spectabilis FRUIT ON HAIR LAMBS FEEDING: DIGESTIBILITY, BLOOD METABOLITES, AND RUMINAL KINETIC

Abstract In recent years sheep, farming has emerged as an alternative production system especially in dry areas. The use of leaves and fruit from some trees has become an alternative for feeding for ruminants; however, studies on these species are scarce. The objective of this study was to evaluate the effect of S. spectabilis fruit meal on in vivo and in vitro digestibility, blood metabolites, and ruminal kinetics in hair lambs. This study was carried out at Las Brisas farm, University of Tolima - Colombia. Twelve male hair lambs with body weight of 20.3 ± 2.5 kg were used. Animals were distributed in an experimental 4x4 Latin square design. The treatments consisted of diets based on Dichanthium spp hay with different inclusion levels of S. spectabilis fruit meal (15, 30, and 45%). A linear increasing effect (P <0.05) was observed for in vivo and in vitro digestibility of dry matter, organic matter, and crude protein; likewise, plasma urea and ruminal degradability increased as the level of supplementation of S. spectabilis increased. The meal of S. spectabilis improves digestibility, protein intake, and ruminal kinetics in hair lambs; therefore, it is suggested as a promising alternative for ruminants feeding in dry tropic regions.
Towards Communal Governed Transactions Among Decentralized Trading Agents

We present a concept in completing transaction among collaborative agents where neither trusted authority nor intermediate facilitator exists. Agents collectively intend and accept that there are valuable objects to be used as medium of exchange. This object, which we call an institutional-token, belongs to an agent through collective acceptance of ownership relation which binds that object to the agent. Transaction between buyer and seller is completed as follows: buyer and seller propose new ownership of the token to all agents, the agents collectively reject prior ownership which binds the token to the buyer and at the same time collectively accept the new ownership relation which binds the same token to the seller in order to "transfer" token to the new owner. Buyer rates the outcome of the transaction and updates its opinion about trustworthiness of the seller. Based on its opinion, agent participates in every collective trust decision whether or not the proposed transaction may proceed. This collaboration scheme enables community to govern transactions in individual level and thus social control emerges to block possible bad behavior, to protect buyer from risky transactions, and to induce good behavior. Finally we describe an implementation scenario in a decentralized P2P file trading community using set of communication protocols and threshold cryptography
Effect of Soil Treatments for Cottony Cushion Scale (Hemiptera: Monophlebidae) Control on Nylanderia fulva (Hymenoptera: Formidicae) Survival and Trailing Activity

Abstract Nylanderia fulva (Mayr) (Hymenoptera: Formicidae), or tawny crazy ant, is an invasive ant from South America that is spreading in the southern US. Extremely large populations of this ant can inundate urban and natural landscapes, and efficient control methods are lacking. This study was conducted to determine if activity of N. fulva would decline after controlling the hemipteran honeydew-producers they were tending. Potted plants infested with cottony cushion scale (Icerya purchasi Maskell) (Hemiptera: Monophlebidae) were treated with 2 imidacloprid insecticide formulations, and changes in N. fulva survival and foraging behavior were monitored. There were fewer ant trails, lower trailing intensity, less foraging, and less nesting in potted plants treated with either product than in the control pots. The use of low application rates of systemic insecticide to reduce honeydewproducing hemipterans, such as cottony cushion scale, could be an important component of the integrated pest management of N. fulva.
Qualitative investigation on bioactive compounds of alfalfa seeds during germination

Sprouts are widely used as an important source of minerals, vitamins and antioxidants. During germination, the enzymes released nutrients from seed in order to grow a new plant. Digestibility of carbohydrates and proteins increase due to conversion in simple sugars and amino acids. Minerals are absorbed from water and transported in germinated seeds. Also, vitamins C and B are formed during metabolic changes of the seeds. Small amounts of sprouts contain a high concentration of bioactive compounds. Alfalfa (Medicago sativa L.) sprouts contain high levels of nutrients with important impact on human health. This nutrients, especially isoflavones, can reduce the menopause side-effects. In vitro studies shows that isoflavones can decrease the incidence of breast cancer, cardiovascular diseases and metabolic diseases. The aim of this study is to observe the effect of sprouting on some compounds like: carbohydrates, saponins, phenolic compounds, alkaloids, flavonoids. The seed of alfalfa were germinated for 6 days. Hidroalcoholic extracts of the sprouts were subject of qualitative determination. The presences of bioactive compounds was confirmed by FTIR investigation of the extracts.
