Super 4PCS Fast Global Pointcloud Registration via Smart Indexing (2014)

Abstract Data acquisition in large‐scale scenes regularly involves accumulating information across multiple scans. A common approach is to locally align scan pairs using Iterative Closest Point (ICP) algorithm (or its variants), but requires static scenes and small motion between scan pairs. This prevents accumulating data across multiple scan sessions and/or different acquisition modalities (e.g., stereo, depth scans). Alternatively, one can use a global registration algorithm allowing scans to be in arbitrary initial poses. The state‐of‐the‐art global registration algorithm, 4PCS, however has a quadratic time complexity in the number of data points. This vastly limits its applicability to acquisition of large environments. We present S uper 4PCS for global pointcloud registration that is optimal, i.e., runs in linear time (in the number of data points) and is also output sensitive in the complexity of the alignment problem based on the (unknown) overlap across scan pairs. Technically, we map the algorithm as an ‘instance problem’ and solve it efficiently using a smart indexing data organization. The algorithm is simple, memory‐efficient, and fast. We demonstrate that S uper 4PCS results in significant speedup over alternative approaches and allows unstructured efficient acquisition of scenes at scales previously not possible.

Conformation Diversity of a Fused‐Ring Pyrazine Derivative on Au(111) and Highly Ordered Pyrolytic Graphite (2015)

Heterocyclic aromatic compounds have attracted considerable attention because of their high carrier mobility that can be exploited in organic field-effect transistors. This contribution presents a comparative study of the packing structure of 3,6-didodecyl-12-(3,6-didodecylphenanthro[9,10-b]phenazin-13-yl)phenanthro[9,10-b]phenazine (DP), an N-heterocyclic aromatic compound, on Au(111) and highly ordered pyrolytic graphite (HOPG). High-resolution scanning tunneling microscopy (STM) combined with atomistic simulations provide a picture of the interface of this organic semiconductor on an electrode that can have an impact on the field-effect transistor (FET) performance. DP molecules adsorb with different conformational isomers (R/S: trans isomers; C: cis isomer) on HOPG and Au(111) substrates. All three isomers are found in the long-range disordered lamella domains on Au(111). In contrast, only the R/S trans isomers self-assemble into stable chiral domains on the HOPG surface. The substrate-dependent adsorption configuration selectivity is supported by theoretical calculations. The van der Waals interaction between the molecules and the substrate dominates the adsorption binding energy of the DP molecules on the solid surface. The results provide molecular evidence of the interface structures of organic semiconductors on electrode surfaces.
What determines crossover wavelengths of metameric pairs with three crossovers? (1990)

Abstract Two matameric stimuli with identical tristimulus values must have spectral radiance distributions that cross at least three times. Many studies have shown that the crossover locations of three‐crossover metamers tend to occur in certain defined regions. This finding has led to hypotheses concerning fundamental aspects of the visual system. In the current article, calculations are reported that prove that crossover locations depend on the spectral properties of the metameric stimuli. For object colors, the spectral properties are determined by colorant obsorption bandwidths. Depending on the absorption bandwidth, crossovers can occur in nearly any region of the visible spectrum. Thus any relationship between crossover wavelengths and properties of the visual system such as maximal responsivities appears coincidental.
Effect of Oxygen and Carbon Dioxide on Photorespiratory Flux Determined from Glycine Accumulation in a Mutant ofArabidopsis thaliana (1983)

Exposure to atmospheric conditions which promote photorespiration strongly inhibits photosynthesis in a mutant of Arabidopsis lacking mitochondrial serine transhydroxymethylase activity, and glycine accumulates as a stable end-product of photorespiratory carbon and nitrogen flow. By providing exogenous serine and ammonia to leaves of the mutant, wild-type photosynthesis rates can be temporarily maintained in the absence of photorespiratory CO2 evolution. In these circumstances, the rate of glycine accumulation provides a direct measure of photorespiratory flux which is not complicated by the efflux and refixation of photorespired CO2, the dilution of radioactive label by endogenous metabolic pools, or non-specific effects of metabolic inhibitors. At the standard atmospheric concentration of CO2, the rate of glycine accumulation in the mutant was proportional to the oxygen concentration, amounting to 53% of the rate of gross CO2-fixation at 21% O2. At normal levels of O2, glycine accumulation was maximal at about 475 μl CO21−1 and was reduced at higher or lower CO2 concentrations, being almost abolished at 3000μ1 CO21−1. These observations are discussed in the context of a model of photorespiration based on the properties of ribulose 1, 5-bisphosphate carboxylase/oxygenase, and in relation to the results of previous attempts to measure photorespiration. Preliminary evidence from 14CO2-labelling experiments which suggests a non-photorespiratory pathway of serine synthesis is also presented.
RULE-BASED EXPERT SYSTEM APPLICATION TO OPTIMIZING OF MULTISCALE MODEL OF HOT FORGING AND HEAT TREATMENT OF TI-6AL-4V (2013)

Nowadays, multiscale methods are increasingly used in modeling of processes and designing of materials. However, there are two serious obstacles to wider application of such methods. One is a demand of computing power, which is present in almost all applications. Increasing of available computing power is not a solution. Exponential growth of computational complexity with increase of accuracy will always lead exceeding of available resources. Therefore, adaptation of multiscale models is important point of interest. The second obstacle is a difficultness of multiscale model design. Model is an abstraction of reality. Therefore, some assumptions have to be done – which phenomena are important and which do not. There is an additional point of interest in multiscale modeling – in which scale the particular phenomena can be modeled with a good balance of accuracy and computing power demand. Usually, there is no single good answer. Designing of a model can be seen as a kind of an optimization process, where the goal is a function of efficiency and reliability. The need of a such process is pointed out in many publications (e. g. [1]), but in the most of cases it have to be done by a researcher himself.

Relationship of Early Pregnancy Waist-to-Hip Ratio versus Body Mass Index with Gestational Diabetes Mellitus and Insulin Resistance (2015)

Increased WHR and BMI in early pregnancy are associated with IR and GDM. BMI is a better predictor of IR compared with WHR. Adding WHR to BMI does not improve its ability to detect GDM or IR.
Recent developments in the field of in vitro biosynthesis of plant beta-glucans (2002)

This chapter reports the use of various detergents for the preparation of vesicles and micelles from plant plasma membranes bearing beta-glucan synthases. The effects of these detergents and other parameters on the in vitro activity of cellulose and (1-->3)-beta-glucan synthases are described. Morphological and structural aspects of the vesicles and micelles; are presented together with the characterization of the products synthesized in vitro by the detergent-extracted beta-glucan synthases. The possible involvement of porins for extrusion of cell wall glucans through plasma membranes as well as future developments for the study of in vitro biosynthesis of these polysaccharides are discussed in relation to these results.
The effect of spinning speed and drawing temperature on structure and properties of poly(ethylene terephthalate) yarns (1989)

Abstract From an industrial point of view, it is effective to have a relation between process conditions and resulting product properties. In practice there are many possible process conditions, whereas properties are generally interrelated in a complex way. Thus, there is a strong need for a physical understanding of the product properties in terms of process settings. This comprehension should also allow one to predict possible consequences for the properties when new process conditions become available. To obtain that physical understanding for the development of production processes of PET yarns, use has been made of a simple two‐phase model of crystalline and amorphous regions. As process parameters the spinning speed and the drawing temperature were chosen. As the drawing temperatures are only known as machine‐setting values, they are simply referred to as “low” and “high.” As mechanical properties the shrinkage, modulus, tenacity, and dynamic mechanical behavior are discussed.
Bcl-2–associated athanogene 3 protects the heart from ischemia/reperfusion injury (2016)

Bcl-2-associated athanogene 3 (BAG3) is an evolutionarily conserved protein expressed at high levels in the heart and the vasculature and in many cancers. While altered BAG3 expression has been associated with cardiac dysfunction, its role in ischemia/reperfusion (I/R) is unknown. To test the hypothesis that BAG3 protects the heart from reperfusion injury, in vivo cardiac function was measured in hearts infected with either recombinant adeno-associated virus serotype 9-expressing (rAAV9-expressing) BAG3 or GFP and subjected to I/R. To elucidate molecular mechanisms by which BAG3 protects against I/R injury, neonatal mouse ventricular cardiomyocytes (NMVCs) in which BAG3 levels were modified by adenovirus expressing (Ad-expressing) BAG3 or siBAG3 were exposed to hypoxia/reoxygenation (H/R). H/R significantly reduced NMVC BAG3 levels, which were associated with enhanced expression of apoptosis markers, decreased expression of autophagy markers, and reduced autophagy flux. The deleterious effects of H/R on apoptosis and autophagy were recapitulated by knockdown of BAG3 with Ad-siBAG3 and were rescued by Ad-BAG3. In vivo, treatment of mice with rAAV9-BAG3 prior to I/R significantly decreased infarct size and improved left ventricular function when compared with mice receiving rAAV9-GFP and improved markers of autophagy and apoptosis. These findings suggest that BAG3 may provide a therapeutic target in patients undergoing reperfusion after myocardial infarction.
Eco-friendly 2-Thiobarbituric acid as a corrosion inhibitor for API 5L X60 steel in simulated sweet oilfield environment: Electrochemical and surface analysis studies (2019)

The corrosion inhibition efficiency of 2-Thiobarbituric acid (TBA) for metal substrate (API X60 steel) in 3.5% NaCl solution saturated with CO<sub>2</sub> gas was probed using various techniques namely, LPR (linear polarization resistance), EIS (electrochemical impedance spectroscopy), and PDP (potentiodynamic polarization). The effects of TBA concentration (25-100 ppm), solution pH (4 and 6), temperature (25-80 °C), and immersion time (2-72 h) on the inhibition efficiency were examined. SEM (scanning electron microscopy) and XPS (X-ray photoelectron spectroscopy) were deployed to explore the corrosion retardation mechanism. TBA exhibited protection efficiencies exceeding 90% for all experimental conditions considered. The excellent anticorrosion performance by TBA was retained up to 72 hours of immersion time. PDP results exhibited that TBA behaved as a mixed type inhibitor. Results from kinetics and thermodynamics analyses indicate that TBA chemically adsorbed on the steel surface following Langmuir isotherm model. The composition of the adsorbed TBA film has been analyzed by XPS.
Chemical exchange saturation transfer for detection of antiretroviral drugs in brain tissue (2021)

CEST contrasts can be used to detect antiretroviral drugs using MRI. Such detection can be used to assess spatial--temporal drug biodistribution. This is most notable within the CNS where drug biodistribution may be more limited with the final goal of better understanding antiretroviral drug-associated efficacy and potential toxicity.
THE EFFECTIVENESS OF PUNISHMENT POLICIES FOR REDUCING TRAFFIC ACCIDENTS (1972)

The present research is an attempt to add a new dimension to the problem of traffic offences and road accidents, by examining the effect of deterrent systems on traffic offences. This is a pilot study summing up the data already collected by the various bodies dealing with this problem. The findings relate to a random sample of 1,638 drivers whose first offence was registered during and after 1966. From this date, and up to the end of 1971, 4,063 offences were registered for these drivers. About 2/3 committed less than 6 offences and 1/3 were recidivists. 48 drivers committed more than 30 offences. With the passing of time, the rate of lesser offences increases and that of serious offences decreases. Offending drivers are made up of two groups. Recidivist drivers whose lack of basic driving capability is due to personality factors; normal drivers whose commission of traffic offences is apparently caused by temporary lack of driving ability due to unclear situations, or to a conglomeration of chance causes on the roads. While most punishments for traffic offences are relatively light, the severity of punishment is correlated with the gravity of the offence and with the driver's history of traffic offences. Severity of punishment is effective only in increasing the period of time between the punished offence and the following one. Severe punishment was found to be positively correlated with recidivism and, drivers who received light punishment for the first offence did not commit additional offences. As soon as the driver has committed two offences, it is possible to predict the number of expected future offences, according to the period of time between the first and second offence. Once personality factors causing lack of basic driving ability have been designated, it will be possible to create a selective system of punishment. The system would test driving ability and cancel licences of drivers who failed to meet requirements of the test.
Properties and mechanism of action of a 17 amino acid, V3 loop-specific microantibody that binds to and neutralizes human immunodeficiency virus type 1 virions. (1999)

Only two virus-neutralizing peptide microantibodies (MicroAbs) have been described and little is known about their mode of action. This report concerns a 17 amino acid cyclized MicroAb, derived from the third complementarity-determining region of the heavy chain of MAb F58 (IgG1), that recognizes the same minimum epitope in the V3 loop of the gp120 envelope protein of human immunodeficiency virus type 1 (HIV-1) as the MAb. The MicroAb was able to bind to and neutralize free virus particles. It was up to 5-fold more efficient in mass terms than F58 IgG and its neutralization rate on a molar basis was only 32-fold lower. The mechanism of neutralization of the MicroAb was also investigated. A high level of neutralization (99%) occurred without any significant decrease in attachment of virus to target C8166 cells. Neutralized virus attached to CD4, the HIV-1 primary receptor. Fusion of virions to cells was partially inhibited by the MicroAb, whereas F58 IgG has been shown to inhibit fusion significantly. Thus, neutralization by the MicroAb appears to be mediated, at least in part, by inhibition of fusion. Control peptides, in which the tyrosine at position 5 or 6 was deleted or changed to phenylalanine, showed no antiviral activity, attesting to the specificity of interaction of the MicroAb with the virion. It therefore appears that the MicroAb acts like an immunoglobulin. The data also show that the MicroAb/MAb F58 epitope on the V3 loop is not involved in attachment of virus to CD4 but is required for subsequent events in early infection.
The Application of a Cantilever-based Strain Sensor to Air Pressure Measurement in Air Blowing Process (2017)

We have developed cantilever-based strain sensors which can be used in the pressure measurement of compressed air. The cantilever beam's distortion due to compressed air blowing is detected by strain sensor located at the fixed end of the cantilever. We evaluated the output characteristics, blowing high-pressure N2 gas to the cantilever sensor. The sensor outputs clearly depended on the N2 gas pressure, the distance between the sensor and the nozzle, and N2 gas blowing position. As a result, we confirmed that our sensors can be applied to the pressure measurement of the compressed air.
Collective Identity and Economic Development A Case Study of How People's Perception of the Collective Identity Affects The Economic Development in Kosovo (2015)

This paper aims to show how identity can be of importance to issues relating to development. More specifically, it deals with how the Kosovar Albanians perception of their collective identity have affected Kosovo’s economic development. The study draws primarily from the theories of Identity Economics and Orientalism and presents a hypothesis which is then tested empirically through the analysis of the in-depth interviews and participant observation carried out in Kosovo. The results show that Kosovar Albanians have, to a degree, internalized the Orientalist discourse, which often portrayed them in racist terms as the ’other’, in their view of their collective identity and that this has had a negative effect on how they perceive their potential in the global economic system, which in turn has undermined the country’s economic development. Thus, identity seems to be of significance when it comes to issues relating to development.
The epidemiology of Ebola haemorrhagic fever in Zaire 1976. (1978)

This article reports on epidemiologic investigations of the Ebola hemorrhagic fever (EbHF) outbreak in Zaire in 1976. Signs and symptoms of EbHF included headache fever abdominal pain nausea and/or vomiting and bleeding. Serum specimens were collected from family and nonfamily primary contacts of possible EbHF cases in 8 villages where there was an outbreak and in 4 villages near the epidemic area in which no cases were reported. From September 1-October 24 1976 there were 318 cases resulting in 280 deaths. A total of 55 villages reported cases. Females accounted for 56% of total cases and those in the 5-14 and 15-29-year age groups were most affected. For 85 of 318 cases the only risk factor appeared to be receipt of 1 or more injections from the outpatient service or general medical wards of the Yambuku Mission Hospital. 149 cases acquired the disease after contact with patients. 5 consecutive transmission generations of EbHF cases were documented. The mean incubation period for cases due to injection was 6.3 days while the incubation spread for person-to-person transmission was 9.5 days. Community members associated the mission hospital with the epidemic and the hospital was closed at the end of September. This essentially stopped injection-transmitted disease and the epidemic terminated shortly thereafter. The source of this virus is believed to be the Sudan where a similar epidemic occurred in August 1976.
