Compress-image quality measures in image-processing applications (2009)

In distributed multimedia applications, an information compression stage is usually necessary. The objective here is to obtain a compression rate that makes the application viable. In this stage, reductions in image quality are often produced in order to reach high rates of compression. This image degradation must be measured and known in order to ensure that it can be limited within an acceptable range of values. The most commonly used metrics are MSE and PSNR. In recent years other metrics have been developed with the aim of obtaining values closer to human subjective evaluation. In this paper, metrics of image compression degradation for image processing applications are analyzed. We propose degradation metrics when the images are used in image processing applications. These are tested on two types of application which show a more than acceptable correlation between the measures and vision algorithms.

An attempt to achieve the direct hydrogenolysis of tetrahydrofurfuryl alcohol in supercritical carbon dioxide (2011)

The use of supercritical carbon dioxide (scCO2) in the hydrogenolysis of tetrahydrofurfuryl alcohol was investigated over a Rh supported MCM-41 catalyst (metal loading ≈ 1%). Without any additive, tetrahydrofurfuryl alcohol was converted to 1,5-pentanediol with high conversion (80.2%) and selectivity (91.2%) under mild reaction conditions (temperature = 80 °C and H2 pressure = 4 MPa). The effects of different variables like CO2 and H2 pressure, temperature and the reaction time were also optimized. A strong influence of CO2 pressure on the conversion was observed. The conversion was increased with pressure due to the enhanced solubility of tetrahydrofurfuryl alcohol in CO2 and reached the maximum at 14 MPa, as the single phase (CO2–H2–substrate) was formed, but the selectivity of 1,5-pentanediol remained unaltered. On the other hand, H2 pressure also changed the conversion as well as the selectivity. Temperature was found to play an important role in enhancing the catalytic efficiency; conversion of the substrate was increased along with the temperature, but the selectivity of 1,5-pentanediol dropped after reaching 120 °C. The Rh catalyst exhibited strikingly different product distribution under the solvent-less conditions compared to scCO2. In addition, instead of CO2, when the reaction was carried out in H2O, the conversion and the selectivity of 1,5-pentanediol decreased substantially. However, addition of only 7 MPa of CO2 modified the conversion and the product selectivity. Under similar reaction conditions, hydrogenolysis of THFA over a Pd catalyst provides a maximum of 50% conversion and the product distribution was different in comparison with Rh catalysts.
Grain Growth in (Ga, Mn)-Codoped ZnO Ceramics (2011)

Grain growth in Ga 2 O 3 and MnO co-doped ZnO was investigated for sintering from 950° to 1250°C in air. Microstructural observation revealed that the samples sintered at lower temperatures consist of uniform equiaxed grains while the samples sintered at higher temperatures consist of plat-like grains, implying that the grain growth mechanism for the examined ZnO ceramics changes when the sintering temperature increases above about 1150°C. The traditional kinetic grain growth equation was employed to analyze the variation of grain size with sintering temperature and sintering holding time. It was shown that the grain growth exponent, n , increases from 2.17 for samples with uniform equiaxed grain structure to 4.30 for samples with plate like grain structure, while the apparent activation energy, Q , increases from 237 kJ/mol for low-temperature-sintered sample to 405 kJ/mol for high-temperature-sintered samples. The increases in both n and Q were mainly attributed to the difference between the grain morphologies in low- and high-temperature ranges. The underestimation of the sizes of the plate-like grains was also considered to be another important origin for the higher values of n and Q for the high-temperature-sintered samples.

Autonomous vehicles: challenges, opportunities, and future implications for transportation policies (2016)

This study investigates the challenges and opportunities pertaining to transportation policies that may arise as a result of emerging autonomous vehicle (AV) technologies. AV technologies can decrease the transportation cost and increase accessibility to low-income households and persons with mobility issues. This emerging technology also has far-reaching applications and implications beyond all current expectations. This paper provides a comprehensive review of the relevant literature and explores a broad spectrum of issues from safety to machine ethics. An indispensable part of a prospective AV development is communication over cars and infrastructure (connected vehicles). A major knowledge gap exists in AV technology with respect to routing behaviors. Connected-vehicle technology provides a great opportunity to implement an efficient and intelligent routing system. To this end, we propose a conceptual navigation model based on a fleet of AVs that are centrally dispatched over a network seeking system optimization. This study contributes to the literature on two fronts: (i) it attempts to shed light on future opportunities as well as possible hurdles associated with AV technology; and (ii) it conceptualizes a navigation model for the AV which leads to highly efficient traffic circulations.
Potentiometric studies on gelatin solutions and gelatin nanoparticle dispersions (2004)

Gelatin is the denaturation product of the protein collagen. The denaturation can be performed by acid hydrolysis or base hydrolysis rendering A- type or B-type gelatin respectively. Gelatin molecules have a nonuniform distribution of 18 amino acids. As a typical protein, gelatin carries both positive and negative charges. Table 1 lists the main amino acids present in gelatin that can contribute towards the presence of a charge on a gelatin macromolecule, together with their respective pKa's.
Process plant condition monitoring and fault diagnosis (1998)

The paper reviews current research work in the field of process condition monitoring and fault diagnosis. The review compares and contrasts the applicability and efficiency of different techniques, and concentrates on methods which monitor the main process variables. From the wide range of methods and process variables, temperature, flowrate and liquid level are used here in comparing the limitations and applications of each method. The scope of the paper ranges from basic, well established techniques to the latest reported monitoring strategies for each of the process variables. Furthermore, the different methods of fault diagnosis deemed to be relevant in process plant are reviewed. The detection of the internal leakage in the control valves and motor faults are discussed in detail, as examples of the monitoring of vital process plant components. The paper then outlines areas of future work, such as the development of a user friendly interface. This interface is based on state transition diagrams (STDs) as well as on the use of a knowledge based system (KBS) to model and diagnose faults in vital process plant components such as control valves.
Comparison of Models for Bubonic Plague Reveals Unique Pathogen Adaptations to the Dermis (2015)

Lastly, based on previous observations where a population bottleneck from the skin to lymph nodes was observed after i.d., but not after s.c., inoculations, we used the latter model as a strategy to identify an additional bottleneck in bacterial dissemination from lymph nodes to the bloodstream. Our data indicate that the more biologically relevant i.d. model of bubonic plague differs significantly from the s.c. model in multiple aspects of infection. These findings reveal adaptations of Y. pestis to the dermis and how these adaptations can define the progression of disease. They also emphasize the importance of using a relevant route of infection when addressing host-pathogen interactions.

High prevalence of the IVS 1 + 1 G to A/<i>GJB2</i> mutation among Czech hearing impaired patients with monoallelic mutation in the coding region of <i>GJB2</i> (2006)

Biallelic pathogenic GJB2 gene mutations cause pre-lingual genetic hearing loss in up to 50% of individuals with bilateral sensorineural hearing loss worldwide. Sequencing of the entire GJB2 gene-coding region in Czech patients with pre-lingual bilateral hearing loss revealed that 10.3% of Czech patients carry only one monoallelic pathogenic mutation in the coding region of the GJB2 gene, which is significantly more than the population frequency of 3.4%. The 309-kb GJB6 deletion, frequent in Spain and France, is very rare in the Czech population. In order to evaluate the impact of the IVS1 + 1 G to A splice site mutation in the non-coding part of the GJB2 gene among Czech patients, we tested all available patients with pre-lingual hearing loss with only one monoallelic mutation in the coding part of GJB2. By sequencing of the exon 1 region of the GJB2 gene and HphI restriction analysis in 20 Czech patients we identified nine patients carrying IVS1 + 1 G to A. Testing for this mutation explained deafness in 45% of Czech GJB2 monoallelic patients. This mutation represents now 4% of GJB2 pathogenic mutations in Czech patients and is the third most common GJB2 mutation found in our cohort of 242 unrelated Czech patients with prelingual hearing loss. A similar frequency may also be expected in other Central European or Slavic populations.

Serum Brain–Derived Neurotrophic Factor and Vascular Endothelial Growth Factor Levels Are Associated With Risk of Stroke and Vascular Brain Injury (2013)

Lower serum BDNF and higher VEGF concentrations were associated with increased risk of incident stroke/TIA. Higher levels of BDNF were also associated with less white matter hyperintensity and better visual memory. Our findings suggest that circulating BDNF and VEGF levels modify risk of clinical and subclinical vascular brain injury.
<title>MPEG-like pyramidal video coder</title> (1993)

In this paper, we propose an MPEG-like video coder using a 3-dimensional (3D) adaptive pyramid. In the 3D adaptive pyramid, the temporal or spatial contraction is selected using the corresponding prediction differences. A video codec is designed using the 3D adaptive pyramid and intra-frame vector quantization. Encoding errors introduced at the upper levels are fed-forward to the lower levels of the pyramid which makes lossless coding possible. The proposed pyramidal video coder has a number of similarities with the MPEG-I video compression standard. Simulation results for the CCITT standard test sequences indicate that the 3D adaptive pyramid reduces the lossless bit rate by a factor of two. Excellent subjective quality as well as objective quality (PSNR value of 36.6 db) are obtained at a bit rate less than T1 rate (i.e., 1.544 Mb/s). Furthermore, smooth transition is achieved in the case of scene changes without sacrificing picture quality.
Transforming growth factor-beta receptor type 2 mutations and microsatellite instability in sporadic colorectal adenomas and carcinomas. (1997)

Frame-shift mutations in a run of 10 adenines (A10) of the transforming growth factor-beta receptor type 2 gene (TGF-beta RII) are commonly seen in inherited and sporadic colonic cancers that exhibit microsatellite instability. A10 mutations and instability also are commonly seen in hereditary nonpolyposis colon cancer-associated adenomas. However, instability is quite rare in sporadic adenomas, and the timing of acquisition of A10 mutations with respect to the sporadic adenoma-carcinoma sequence has not been reported. We evaluated 100 sporadic colorectal cancers and 164 sporadic adenomas for microsatellite instability with a set of 10 tetranucleotide polymerase chain reaction primer sets and for A10 frame-shift mutations. A10 mutations were significantly associated with microsatellite instability in colorectal cancers, being seen in 9 of 11 cancers with 50% or greater instability and in 0 of 89 tumors with less than 50% instability (P < 0.0001). A10 mutations were not detected in any adenomas, only three of which (1.8%) exhibited significant (30% or greater) instability. We conclude that both TGF-beta RII frame-shift mutations and microsatellite instability occur at a relatively late stage of sporadic colorectal tumorigenesis. A10 frame-shift mutations appear to be restricted to sporadic colorectal cancers with extensive microsatellite instability.
Neonatal Necrotizing Enterocolitis – Inflammation and Intestinal Immaturity (2009)

Neonatal necrotizing enterocolitis is a devastating inflammatory bowel disease of premature infants. The pathogenesis remains incompletely understood and there is no specific treatment. Efforts are ongoing to understand aspects of intestinal immaturity which contribute to susceptibility to this disease. This review focuses on bacterial colonization patterns, intestinal barrier function, and inflammatory responses of immature enterocytes leading to a unique vulnerability of the preterm gut. In addition the possible therapeutic potential of factors in human milk and probiotic bacteria is discussed.
Spatial and temporal regulation of GLUT4 translocation by flotillin‐1 and caveolin‐3 in skeletal muscle cells (2006)

Skeletal muscle tissue is one of the main sites where glucose uptake occurs in response to insulin. The glucose transporter type-4 (GLUT4) is primarily responsible for the insulin-stimulated increase in glucose uptake. Upon insulin stimulation, GLUT4 is recruited from intracellular reserves to the plasma membrane. The molecular mechanisms that regulate the translocation of GLUT4 to the sarcolemma remain to be fully identified. Here, we demonstrate that GLUT4 is localized to perinuclear stores that contain flotillin-1, a marker of lipid rafts, in skeletal muscle cells. Stimulation with insulin for 10 min results in the translocation of flotillin-1/GLUT4-containing domains to the plasma membrane in a PI3K- and PKCzeta-dependent manner. We also demonstrate that caveolin-3, a marker of caveolae, is required for the insulin receptor-mediated activation of the PI3K-dependent pathway, which occurs 2 min after insulin stimulation. In fact, we demonstrate that lack of caveolin-3 significantly reduces insulin-stimulated glucose uptake in caveolin-3 null myotubes by inhibiting both PI3K and Akt, as well as the movement of GLUT4 to the plasma membrane. Interestingly, caveolin-3 moves away from the plasma membrane toward the cytoplasm 5 min after insulin stimulation and temporarily interacts with flotillin-1/GLUT4-containing domains before they reach the sarcolemma, with the consequent movement of the insulin receptor from caveolin-3-containing domains to flotillin-1-containing domains. Such translocation temporally matches the insulin-stimulated movement of Cbl and CrkII in flotillin-1/GLUT4-containing domains, as well as the activation of the GDP-GTP exchange factor C3G. Disruption of flotillin-1-based domains prevents the activation of C3G, movement of GLUT4 to the sarcolemma, and glucose uptake in response to insulin. Thus, the activation of the Cbl/C3G/TC10-dependent pathway, which occurs before flotillin-1/GLUT4-containing domains reach the plasma membrane, is flotillin-1 mediated and follows the activation of the PI3K-mediated signaling. Taken together, these results indicate that flotillin-1 and caveolin-3 may regulate muscle energy metabolism through the spatial and temporal segregation of key components of the insulin signaling.
Water Tank Monitoring and Visualization System Using Smart-Phones (2013)

Monitoring sensor networks that consist of many valves, pumps and tanks is an important task for managing large ships. Existing water tank monitoring systems are only provided for PC environment. In this paper we propose a new method to monitor water tanks on a smart phone. Before presenting our system, we analyze the water tank system and define the discussed problem formally. Based on this analysis, we develop our monitoring system and elaborate on out the implementation. We also show that our system visualizes sensor data using a simple and intuitive user interface.
On the State of Evolutionary Computation (1993)

In the past few years the evolutionary computation landscape has been rapidly changing as a result of increased levels of interaction between various research groups and the injection of new ideas which challenge old tenets. The effect has been simultaneously exciting, invigorating, annoying, and bewildering to the old-timers as well as the new-comers to the field. Emerging out of all of this activity are the beginnings of some structure, some common themes, and some agreement on important open issues. We attempt to summarize these emergent properties in this paper. 1 INTRODUCTION The field of evolutionary computation (EC) is in a stage of tremendous growth as witnessed by the increasing number of conferences, workshops, and papers in the area as well as the emergence of a central journal for the field. Until recently, the field could be characterized as a fairly amorphous collection of independent research groups each representing a particular approach to evolutionary computation wit...

Effect of stress of examination on serum cortisol level and cd4 cell count in male undergraduates at Igbinedion University, Nigeria (2014)

Aim: To assess the effect of stress of examination on serum cortisol level and CD4 cell count in young male students at Igbinedion University. Methods: A cross sectional laboratory based analysis was adopted for this study. A total of 204 male undergraduate volunteers (age 22 + 1.0 years, body mass index 23 + 0.5 kg/m2) were randomly recruited for the study. Total white blood cell (TWBC) was determined using the sysmex® Automated Hematology Analyzer. CD4 cell count was estimated using Partec cyflow counter, while serum cortisol level was determined by enzyme linked immuno sorbent assay technique. Results: There was a significant increase (P < 0.05) in the serum cortisol level at Stage A (1st day of the semester) when compared with Stage B (midway in the semester) and Stage C (morning of the examination), while there was significant decrease (P < 0.05) in the TWBC count and CD4 cell count at Stage A when compared with Stage B and Stage C. Conclusion: The stress of examination inhibits proliferation of CD4 cells with the elevation of serum cortisol as a possible mediator.   Keywords: Examination, Stress, Cortisol, CD4 cell.
