A Novel Approach of Laser Scanning Point Cloud Quality Assessment Using Wavelet Analysis

3D point clouds are essential sources in acquiring information for many applications such as cultural heritage protection/restoration, building information modeling and management or architectonic documentation. The quality of TLS point clouds is very important in such applications because of its completeness, and structural information capacity. With a growing demand on photogrammetric products accuracy, point cloud quality assessment has become more and more important topic. The most common type of point cloud error is measurement noise, most commonly around the edge of an object (edge of a building roof). The goal of point cloud quality assessment is to define its inner accuracy and the discrepancies especially the noise level of data. There is several statistical methods for 3D point cloud quality evaluation, but these methods threat whole signal as a unity and do not include particular characteristic. In this paper a method of quality assessment using wavelet analysis is presented.
Some chemical components of mitochondria and microsomes from germinating castor beans.

Increasing interest in the biochemical activities of mitochondria from plants has made it desirable to have more knowledge ofthe chemical composition of such particles. We have, accordingly, extended our investigation of the highly active mitochondrial fraction from the endosperm of germinating castor bean (Beevers & Walker, 1956; Walker & Beevers, 1956) by studying some of the components of particulate preparations from this material. A considerable amount of analytical work has been done with particles ofanimal origin, but the data on biochemically active particles from plants is still rather meagre (see reviews by Goddard & Stafford (1954), and Hackett (1955). Previous work is discussed in papers by Martin & Morton (1956a, b), who have made thorough examinations of the chemical composition of mitochondria and microsomes derived from silver-beet petiole and from wheat roots. Another recent contribution provides data on the ribonucleic acid (RNA) and nitrogen contents of active mitochondria and microsomes from peanut (Kmetec & Newcomb (1956)). In the next paper (Akazawa & Beevers, 1957), there are shown some very striking changes in the amount and intrinsic activity of the mitochondria derived from the endosperm as the castor-bean seedling grows to the 8 days stage, when the endosperm has been depleted. It was therefore of some interest to see if there were differences in the composition of the particles derived from seedlings of different ages. The inforimation so obtained allows some conclusions to be drawn about the process of mitochondrial production and particularly about the decline in efficiency which characterizes the mitochondria from the ageing endosperm. Osmotic phenomena are of some importance in determining the behaviour of plant mitochondria, as they are in those from animal tissues, and Laties (1953) and Farrant, Robertson & Wilkins (1953) have investigated aspects of the osmotic behaviour of plant mitochondria. These observations have been supplemented here by data on the percentage dry weight of mitochondrial particles and the changes in this value under a variety ofexperimental conditions.

Intratympanic Injection of Dexamethasone: Time Course of Inner Ear Distribution and Conversion to Its Active Form

Hypothesis: Intratympanically injected dexamethasone 21-phosphate is converted to its active form dexamethasone in the inner ear and follows the distribution of the glucocorticoid receptor. Background: Although dexamethasone is routinely delivered intratympanically for hearing loss, we know little of its inner ear pharmacokinetics. Dexamethasone 21-phosphate is the pharmaceutical compound available for injection, but it must be converted to its biologically active form (dexamethasone) to bind to the glucocorticoid receptor. Therefore, the current study was conducted to determine the time course of dexamethasone 21-phosphate movement from the middle ear into the inner ear, its conversion to dexamethasone, and the distribution of both forms relative to the glucocorticoid receptor. Methods: BALB/c mice were injected intratympanically with the prodrug dexamethasone 21-phosphate and inner ears collected at postinjection times ranging from 5 minutes to 7 days. Ears were immunohistochemically stained for dexamethasone 21-phosphate, dexamethasone, and the glucocorticoid receptor. Results: Both forms of dexamethasone were seen in the inner ear within 15 minutes, reaching their highest staining intensity at 1 hour. Neither drug was seen after 24 hours. The strongest staining occurred in the spiral ligament, organ of Corti, spiral ganglion, and vestibular sensory epithelia. Distribution of the drug paralleled locations of the glucocorticoid receptor except in the stria vascularis marginal cells, which stained heavily for the receptor but not the drug. Conclusion: Dexamethasone rapidly travels from the middle ear into the inner ear and converts to its active form. The drug distribution follows that of the glucocorticoid receptor. However, it probably has little impact on ear tissues after 24 hours.
Pitfalls in measuring plasma cholesterol in the Smith-Lemli-Opitz syndrome.

Correct quantitative results for plasma cholesterol, 7-dehydrocholesterol (7-DHC), and 8-dehydrocholesterol (8-DHC) are invaluable for making the correct diagnosis in patients with the Smith-Lemli-Opitz syndrome (SLO) and for biochemical monitoring of these patients during therapy. The enzymatic method for cholesterol measurement based on cholesterol oxidase gives falsely high values for plasma cholesterol in samples from patients with SLO. Both 7-DHC and 8-DHC contribute substantially to the test result, given that they are accepted substrates of cholesterol oxidase. All cholesterol methods making use of this enzyme are expected to give unreliable results with plasma samples from SLO patients. Cholesterol values found with these methods may be low-normal in individual cases with SLO. Therefore, other techniques for measuring cholesterol, 7-DHC, and 8-DHC, e.g., gas chromatography, should be used for diagnosing these patients and for follow-up during therapy. However, a normal value for plasma cholesterol, as obtained by gas chromatography, does not exclude SLO. The diagnosis should always be confirmed or excluded by testing for the presence of high concentrations of 7-DHC and 8-DHC in plasma. We found that one patient with a severe form of the disease had a plasma cholesterol concentration of 20 micromol/L-to our knowledge, the lowest value ever recorded in a human being.
Use of force sensors to detect and analyse lameness in dairy cows

Force sensors were used to detect lameness in dairy cows in two trials. In the first trial, leg weights were recorded during approximately 12,000 milkings with balances built into the floor of the milking robot. Cows that put less weight on one leg or kicked frequently during milking were checked first with a locomotion scoring system and then with a clinical inspection. A locomotion score of more than 2 was considered lame, and these cows' hooves were examined at hoof trimming to determine the cause and to identify any hoof lesions. In the second trial 315 locomotion scores were recorded and compared with force sensor data. The force sensors proved to be a good method for recognising lameness. Computer curves drawn from force sensor data helped to find differences between leg weights, thus indicating lameness and its duration. Sole ulcers and white line disease were identified more quickly by force sensors than by locomotion scoring, but joint problems were more easily detected by locomotion scoring.
Identification of glucose kinase‐dependent and ‐independent pathways for carbon control of primary metabolism, development and antibiotic production in Streptomyces coelicolor by quantitative proteomics

Members of the soil‐dwelling prokaryotic genus Streptomyces are indispensable for the recycling of complex polysaccharides, and produce a wide range of natural products. Nutrient availability is a major determinant for the switch to development and antibiotic production in streptomycetes. Carbon catabolite repression (CCR), a main signalling pathway underlying this phenomenon, was so far considered fully dependent on the glycolytic enzyme glucose kinase (Glk). Here we provide evidence of a novel Glk‐independent pathway in Streptomyces coelicolor, using advanced proteomics that allowed the comparison of the expression of some 2000 proteins, including virtually all enzymes for central metabolism. While CCR and inducer exclusion of enzymes for primary and secondary metabolism and precursor supply for natural products is mostly mediated via Glk, enzymes for the urea cycle, as well as for biosynthesis of the γ‐butyrolactone Scb1 and the responsive cryptic polyketide Cpk are subject to Glk‐independent CCR. Deletion of glkA led to strong downregulation of biosynthetic proteins for prodigionins and calcium‐dependent antibiotic (CDA) in mannitol‐grown cultures. Repression of bldB, bldN, and its target bldM may explain the poor development of S. coelicolor on solid‐grown cultures containing glucose. A new model for carbon catabolite repression in streptomycetes is presented.
Statistical analysis of electromagnetic environment in electrically large enclosure with aperture array

In this paper, the electromagnetic (EM) environment inside four kinds of enclosure are analyzed by statistical method. The external electromagnetic energy is coupled into enclosure through nine kinds of aperture array with equivalent areas respectively. The computational results are given in the form of probability density function (PDF) to show the interior EM characteristics. Statistics can effectively avoid high frequency response sensitivity (HFRS) and it can be used to inform useful global shielding effectiveness (SE) for enclosures.
Tapered Velocity Mode-Selective Couplers

In this paper tapered velocity mode-selective couplers are presented. These tapered couplers are approximately adiabatic devices which unlike standard mode-selective couplers, do not rely on precise phase conditions to be satisfied over an extended length, to achieve their mode-selective functionality. Therefore these mode couplers permit ultra-wideband mode-division multiplexing of few-mode waveguides. Moreover, their behavior is largely independent of parameters such as index contrast and the precise coupler dimensions. The mode-selective functionality is demonstrated in slab geometry, with the principles generalizing to planar or fiber-based devices.
Compact and high-speed hardware architectures for hash function tiger

Compact and high-speed hardware architectures for the 192-bit hash function Tiger are proposed and their gate counts and throughputs are evaluated using a 90-nm CMOS standard cell library. The implementations achieve practical performances of 22.5 K with 2.2 Gbps and 46.4 Kgates with 6.95 Gbps. These throughputs are 1.5−2 times higher than those of the SHA hash family SHA-256/-512, but the hardware efficiencies (defined as throughput per gate) of Tiger are lower than those of SHA and are half those of the Whirlpool hash function. Hardware performance is one of the most important features for hash functions to be selected as a next standard algorithm after SHA. Therefore, the requirements for hash functions to achieve flexible and high-performance circuits are also clarified through this study by analyzing the characteristics of structure and basic components of each algorithm from the viewpoint of hardware implementation.
ProvDS: Uncertain Provenance Management over Incomplete Linked Data Streams

Data processing in distributed environments is often across heterogeneous systems, bearing the need to exchange provenance information, such as, how and when data was generated, combined, recombined, and processed. Distributed systems involve multiple participants and data sources which can produce unreliable, erroneous data. Besides, there maybe exists oceans amount of data to deal with, e.g., in fields such as Internet of Things (IoT) and Smart Cities. Therefore, dynamic stream-based data processing mechanisms are more reasonable in these environments. Hence, we propose provenance and recovery-aware data management techniques that take dynamic, incomplete streams as inputs, and simultaneously recover the missing data and compute the provenance over the reconstructed streams. Unlike traditional provenance management techniques, which are applied on complete and static data, our research focuses on dynamic and incomplete heterogeneous data.
Dynamic expression of Thyrotropin‐releasing hormone in the mouse definitive endoderm

Thyrotropin‐releasing hormone (TRH) is a well‐characterized regulator of the hypothalamic–pituitary–thyroid endocrine axis. Here, we describe the expression of Trh during early embryonic development in the mouse. We find Trh to be highly expressed during postimplantation stages in the mouse embryo, with expression first observed in the epiblast at embryonic day (E) 6.5. During gastrulation, Trh is expressed in the newly formed definitive endoderm cells, and at embryonic day (E) 7.75, marks the entire definitive endoderm. Subsequently, Trh mRNA levels rapidly decrease such that, by E9.0, expression in the definitive endoderm is no longer detected, after which neural expression predominates. Thus, Trh is expressed dynamically and specifically in the developing mouse definitive endoderm from E7.0 to E8.5. Trh is unique among definitive endoderm markers as it transiently marks the entire definitive endoderm population and is not expressed in the extraembryonic endoderm. Trh will be a valuable tool to study definitive endoderm formation in the mouse embryo. Developmental Dynamics 236:2909–2917, 2007. © 2007 Wiley‐Liss, Inc.
Factor Analysis with Data Mining Technique in Higher Educational Student Drop Out

The increase of students’ drop out rate in higher education is one of the important problems in most institutions. The discovery of hidden knowledge from the educational data system by the effective process of data mining technology to analyze factors affecting student drop out can lead to a better academic planning and management to reduce students drop out rate, as well as can inform valuable information for decision making of steak holder to improve the quality of higher educational system. In this paper, we consider three issues of factors affecting students’ drop out rate. These factors are conditions related to the students before admission, factors related to the students during the study periods in the university, and all factors including the target value to be predict for factors analysis. We use tree-based classification algorithm, J48 or C4.5, and Naïve Bayes to analyze the data. To evaluated the model, we use both 10-fold cross validation and supplied test set methods. Accuracy rate was satisfactory and the induced models are actionable and potentially applicable to higher education planning.

Improved modeling of soil organic carbon in a semiarid region of Central East Kazakhstan using EPIC

Inappropriate land use and soil mismanagement produced wide-scale soil and environmental degradation to the short-grass steppe ecosystem in the semiarid region of central east Kazakhstan. A limitation for determining the impacts of land use changes on soil organic carbon (SOC) is the dearth of information on SOC stocks under the predominant land uses in the region. Here we used the Environmental Policy Integrated Climate (EPIC) model to study long-term impacts of land use changes and soil management on SOC to a depth of 50 cm during 1955–2030, in degraded agricultural lands of central east Kazakhstan. Simulated land uses were: native rangeland vegetation, wheat (Triticum aestivum L.), wheatgrass (Agropyron cristatum L.), and abandoned croplands. The EPIC model was initialized with soil properties obtained from a soil map of the study area. Data on crop management, fertilizer application and tillage practices were gathered from local expert knowledge. Simulations were performed for each polygon on a land use classification map, resulting in 4661 simulations. Our results showed that simulated SOC explained 50% of the variation in measured SOC. Of the 1.38 million hectares in the study area, 78% were under native vegetation, 3% cultivated to wheat, 8% on wheatgrass, and 11% were abandoned croplands in 2005. If land use remained constant, total stock of SOC would decrease at an annual rate of 723 kg C ha−1. However, if best management practices are implemented, resulting in reallocation of land use according to the land capability with abandoned croplands being converted to reduced-tillage wheat or wheatgrass, total stock of SOC would increase to an equivalent of 4700 kg C ha−1 yr−1. Combining land use classification and soil maps with EPIC, proved valid for studying impacts of land use changes and management practices on SOC; an important aspect of this approach is the ability to scale up site-specific SOC to the region. With the available data, EPIC produced relatively accurate results but more data on spatial and temporal variation in SOC are needed to improve model calibration and validation.
Photometric stereo using point light sources

Practical lamps for undersea illumination are closely approximated by point sources, the light from which diverges and also attenuates due to scattering and absorption by the water. The objective is to determine the error introduced by these departures from the usual lighting assumptions of photometric stereo and to find an approach to solution of the brightness equations. It is demonstrated that an iterative approach to photometric stereo, plus a sparse range map containing as little as one range datum for each object in the scene, is sufficient to permit determination of the surface gradients. Simulation indicated that the method improves accuracy and was robust with respect to measurement error in both sparse range data and attenuation length. <<ETX>>
