Double infection of heteroserotypes of dengue viruses in field populations of Aedes aegypti and Aedes albopictus (Diptera: Culicidae) and serological features of dengue viruses found in patients in southern Thailand. (2006)

In order to understand more about the epidemiology of DHF, a study of the type of dengue viruses and vectors under natural conditions was carried out. Mosquito vectors in the field and the serum of DHF patients in southern Thailand were examined. The two mosquito species are abundant and DHF incidence remains high in this region. Dengue viruses were examined in field-caught mosquitoes by RT-PCR technique. The mosquitoes were caught in 4 provinces: Krabi, Phuket, Phang-Nga and Surat Thani during the late dry season until the early rainy season in 2005. Three dengue serotypes (DEN-2, DEN-3, DEN-4) were detected in Ae. aegypti males and females, and 2 (DEN-2, DEN-3) were detected in Ae. albopictus females. Double infection with 2 serotypes of dengue viruses (DEN-2 and DEN-3) were detected in Ae. aegypti males and females and Ae. albopictus females. DEN-2 and DEN-1 were the most prevalent serotypes found in the serum of the patients in this area, followed by DEN-4 and DEN-3. The prevalence of the predominant dengue serotype varied from province to province. Detection of viruses in adult male mosquitoes reveals the role of transovarial transmission of dengue viruses in field populations of DHF vectors and elucidates circulation of dengue viruses in vectors in the natural environment of endemic areas. The incidence of multiple serotypes of dengue virus in Ae. aegypti and Ae. albopictus in the same area points toward a high risk for an epidemic of DHF. These findings provide greater understanding of the relationship among mosquito vectors, virus transmission and DHF epidemiology in endemic areas.

Electron Transport at the TiO2 Surfaces of Rutile, Anatase, and Strontium Titanate: The Influence of Orbital Corrugation (2015)

The two-dimensional electron gas in SrTiO3 created by an overlayer of amorphous LaAlO3 is compared with those at the TiO2-terminated surfaces of rutile and anatase. Differences in conductivity are explained in terms of the limiting Ti–O–Ti bond angles (orbital corrugation), band dispersion, and polaron formation. At 300 K, the sheet conductivity and mobility of anatase exceed those for SrTiO3 or rutile by one or two orders of magnitude, respectively. The electrons in rutile become localized below 25 K.

Cross-Reaction ofStenotrophomonasandXanthomonasSpecies in a 23S rRNA Gene-Directed PCR for Detection ofS. maltophilia (2008)

Stenotrophomonas maltophilia is an opportunistic pathogen that occupies a variety of niches both inside and outside hospitals, mostly in moist environments ([1][1]). Whitby et al. recently developed species-specific PCR (SS-PCR) primers directed at a region of the S. maltophilia 23S rRNA gene to
Image super-resolution using gradient profile prior (2008)

In this paper, we propose an image super-resolution approach using a novel generic image prior - gradient profile prior, which is a parametric prior describing the shape and the sharpness of the image gradients. Using the gradient profile prior learned from a large number of natural images, we can provide a constraint on image gradients when we estimate a hi-resolution image from a low-resolution image. With this simple but very effective prior, we are able to produce state-of-the-art results. The reconstructed hi-resolution image is sharp while has rare ringing or jaggy artifacts.
Hormonal and environmental interactions on thyroid function in the chick embryo and posthatching chicken (1984)

Recent research has focused on developmental changes in thyroxine (T4) metabolism as well as hormonal and environmental interactions upon peripheral monodeiodination. Toward the end of incubation and the time of air space membrane perforation, concentrations of 3,3', 5'-triiodothyronine T3 increase more rapidly than T4, while reverse T3 (rT3) decreases. Administration of glucocorticoids or prolactin (hormones known to increase at the end of incubation) 2 to 3 days prior to air chamber perforation can induce this change in T4 metabolism. Attention has been focused on two major environmental factors that influence T4 concentrations in posthatch chicks. T4 disappearance rate and peripheral T4 conversion are adjusted during thermal acclimation. More T3 will be generated in cold-exposed chickens, and more rT3 will be produced at higher ambient temperatures. Peripheral T4 metabolism acts as an independent regulation pathway but accompanies changes in hypothalamo-thyroid activity. Changes in thyroid hormone levels following ambient temperature changes, therefore, are the result of a balance between central and peripheral control mechanisms, depending on age of the animal and degree and duration of the temperature change. In the hen, feeding also plays an important role in the regulation of the absolute levels and daily rhythms of plasma thyroid hormones. Fasting results in an increase in circulating T4 levels, but a decrease in T3 levels, owing to a lower 5'deiodinase activity, and also abolishes the circadian circulating T3 rhythm.
Thermal stability of single crystalline alpha gallium oxide films on sapphire substrates (2013)

Abstract High quality single crystalline alpha gallium oxide (α‐Ga 2 O 3 ) films, as highlighted by the X‐ray diffraction ω‐scan full‐width at half maximum of as small as 30 arcsec, were prepared by the mist chemical vapor deposition (CVD). The quality of the film was markedly dependent of the carrier gas flow rate, so we need careful attention for the optimum growth conditions. The thermal stability of α‐Ga 2 O 3 films was investigated by studying their thermal stability under thermal annealing in terms of the structural and optical properties. It was found that α‐Ga 2 O 3 films grown at 470 °C are stable until 550 °C, but are gradually transformed to β‐Ga 2 O 3 over 600 °C. Finally, β‐Ga 2 O 3 films only existed at 700 °C. So the device processes for α‐Ga 2 O 3 should be done below 550 °C to avoid phase transformation. (© 2013 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
Corporate Environmental Reporting: An Emerging Issue in the Corporate World (2009)

Corporate environmental reporting becomes a crucial issue in today’s corporate reporting. The present status and future focus gives every indication that it is going to capture a permanent position in the bundle of general-purpose financial statement. Because, the corporate reporting is for the stakeholders and every stakeholders show a keen interest on such disclosure. Protecting the environment is the social responsibility and commitment of corporations towards the society. It is believed that corporation is responsible for the environmental crisis and so they should pay for this (cost-benefit trade off). However, reporting is mostly guided by standards, guidelines etc. And, we do not have any standards designed for such disclosure. So, such reporting is still voluntary that has no specific format and style. Voluntary disclosure often leads to non-disclosure and mandatory disclosure leads to minimal disclosure. Thus, environmental disclosure should have both type of orientation, as it is a question of life and sustainability. The paper gives a conceptual discussion on corporate environmental reporting and guidelines. It also gives a literature review of current reporting practices to highlights the developments till date. And, this concludes that the level, extent and style of disclosure are not satisfactory at all in any respect. The professionals and respective regulatory authorities should come forward with stricter standards and guidelines to this issue that is the demand of time.
Analytical Jet Spectroscopy of Tyrosine and its Analogs Using a Pulsed Laser Desorption Volatilization Method (1988)

Pulsed laser desorption is used as a means of volatilizing nonvolatile and thermally labile molecules for entrainment into a supersonic jet expansion. The jet expansion provides ultracold molecules whose sharp spectral features are probed by resonant two-photon ionization spectroscopy in a time-of-flight mass spectrometer. Such jet-cooled spectra are demonstrated for tyrosine and related structural analogs. Despite the similarity between these tyrosine-based compounds, electronic spectroscopy is shown to be a sensitive probe of small structural changes in these related biological compounds.

A reverse transcriptase-polymerase chain reaction assay for detection of viable Escherichia coli O157:H7: investigation of specific target genes (2002)

Prior to detection or identification from an environmental or food sample E. coli O157:H7 may be exposed to many harsh conditions that influence nucleic acid (RNA and DNA) stability. This study gives an insight into the effects of temperature and nutrient deprivation on identification of viable cells using RT-PCR. It also suggests that, if RT-PCR is to be used for detection of live cells in a sample without enrichment, 10(7) cfu of the target organism are required.
Atomistic Characterisation of Li+ Mobility and Conductivity in Li7−xPS6−xIx Argyrodites from Molecular Dynamics Simulations, Solid‐State NMR, and Impedance Spectroscopy (2010)

The atomistic mechanisms of Li(+) ion mobility/conductivity in Li(7-x)PS(6-x)I(x) argyrodites are explored from both experimental and theoretical viewpoints. Ionic conductivity in the title compound is associated with a solid-solid phase transition, which was characterised by low-temperature differential scanning calorimetry, (7)Li and (127)I NMR investigations, impedance measurements and molecular dynamics simulations. The NMR signals of both isotopes are dominated by anisotropic interactions at low temperatures. A significant narrowing of the NMR signal indicates a motional averaging of the anisotropic interactions above 177+/-2 K. The activation energy to ionic conductivity was assessed from both impedance spectroscopy and molecular dynamics simulations. The latter revealed that a series of interstitial sites become accessible to the Li(+) ions, whilst the remaining ions stay at their respective sites in the argyrodite lattice. The interstitial positions each correspond to the centres of tetrahedra of S/I atoms, and differ only in terms of their common corners, edges, or faces with adjacent PS(4) tetrahedra. From connectivity analyses and free-energy rankings, a specific tetrahedron is identified as the key restriction to ionic conductivity, and is clearly differentiated from local mobility, which follows a different mechanism with much lower activation energy. Interpolation of the lattice parameters as derived from X-ray diffraction experiments indicates a homogeneity range for Li(7-x)PS(6-x)I(x) with 0.97 < or = x < or = 1.00. Within this range, molecular dynamics simulations predict Li(+) conductivity at ambient conditions to vary considerably.
Symmetry detection of occluded point cloud using deep learning (2021)

Before our paper, some papers have approached symmetry detection in various attacks of lines. Deep learning has taken off in recent years in many fields in computer graphics, and we are thinking of using big data to solve the symmetry detection problem. Our work aims to solve a niche problem: using deep learning to detect symmetry in objects of the occluded point cloud. As far as we know, we are the first piece of work to deal with such a problem in deep learning settings. We employ points on the symmetry plane and normal vectors as double supervision to help us pinpoint the symmetry plane. Experiments conducted on the YCB-video dataset prove the effectiveness of the work and our method. To see our implementation, please visit https://github.com/Allen--Wu/dense_symmetry.

Endogenous adult neural stem cells: Limits and potential to repair the injured central nervous system (2004)

Mitotic activity persists in various regions of the adult mammal CNS. While evidences of neurogenesis appeared, many studies focused on the features of the adult stem cells from germinative areas such as the subventricular zone of the lateral ventricles, the dentate gyrus of the hippocampus, the cortex, the fourth ventricle and the central canal of the spinal cord. In the present paper, we review the potentialities of the adult germinative areas in terms of proliferation, migration and differentiation in non pathological situation and in response to different type of CNS injury. Adult endogenous stem cells are activated in response to various injuries but their capacities to migrate and to undergo either neurogenesis or gliogenesis differ according to the lesion-type and the germinative zone from which they arise. Different works demonstrated that epigenic factors such as growth factors can enhance the repair potential of the adult stem cells. Reactivation and mobilization of endogenous stem cells as well as demonstration of their long-term survival and functionality appear to be interesting strategies to investigate in order to promote endogenous repair of the adult CNS.

O objetivo desse trabalho, foi avaliar o selamento de restaurações de cimento de ionômero de vidro (CIV), utilizando como pré-tratamento da dentina o ácido poliacrílico, ácido tânico e laser Nd:YAG. Foram preparados 40 terceiros molares humanos hígidos e extraídos por indicação cirúrgica, limpos e armazenados em soro fisiológico. Foram feitos preparos Classe V, na face vestibular com ponta esférica diamantada no 3018 – KG Sorensen, com dimensões 3,0 mm de diâmetro por 1,5 mm de profundidade. A seguir, os dentes foram divididos em 4 grupos, de acordo com o pré-tratamento da dentina: restauração sem tratamento prévio da dentina (grupo 1); restauração com tratamento prévio da dentina utilizando o ácido poliacrílico a 11,5% por 60 seg. (grupo 2); restauração com tratamento prévio da dentina utilizando o ácido tânico à 25%, por 30 seg. (grupo 3); restauração com tratamento prévio da dentina utilizando o laser Nd:YAG, com 160 mJ/pulso, 10 Hz, 1,6 W, com tempo de aplicação de 5 seg., sem contato da fibra com a superfície dentinária (grupo 4). As cavidades foram restauradas com CIVRM (Vitremer 3M), e submetidos à termociclagem, com banhos alternados de 5o e 55o C (+ ou - 2oC) e com 300 ciclos por 30 segundos cada banho, em seguida imersos em solução Rodamina B à 2%, à 37o, por 24 horas. Os dentes foram seccionados e submetidos à leitura das infiltrações em estereomicroscópio. Concluiu-se que os diferentes tratamentos da dentina não influenciaram significativamenteos resultados do selamento marginal de restauraçãoCIVRM.
PECTINOLYTIC ACTIVITY OF Boeremia strasseri THE CAUSAL AGENT OF BLACK STEM AND RHIZOMES ROT OF PEPPERMINT (2015)

Pectinases have multiple nature and various forms which are necessary for hydrolysis of pectin in natural processes. The pectinolytic activity of three isolates of the pathogenic fungus Boeremia strasseri was demonstrated. The pectinases production was studied using a liquid Mandels-Weber medium, containing 1.0% citric pectin as a carbon source. Optimum pH and temperature for pectinases activity were 4.7 and 40°C respec-tively. The pectinases were totally stable at 40°C for 80 min. The greatest loss of activity was observed during the heating of the enzymes at 70°C.

Decoupling animation development of realtime applications in distributed environments (2008)

The conditions arising for the realization of visualization-oriented applications have recently changed. Especially in pervasive environments, where predominantly small and limited devices are present, the need for a distributed realization of relevant visualization processes is present. Due to the impact of user interaction at runtime, issued by e.g. pervasive applications, animations needs to be describable by developers in a functional manner, relative to an animationpsilas current state. Therefore, we propose a framework for the development of animation-centric visualizations in distributed environments. Decoupling the development of animations in complexity and representation from their final visualization is thereby achieved by the modelling and realization of a distributed visualization architecture and an according functional animation related programming pattern. Finally, we describe stEVE, a case study for the suitability of our framework aiming at the demonstration of biologically inspired processes in next generation computing systems.
Stimulation of eicosapentaenoic acid metabolism in washed human platelets by 12-hydroperoxyeicosatetraenoic acid. (1983)

Washed human platelets were not able to convert eicosapentaenoic acid (EPA) to thromboxane B3 (TXB3) and 12-hydroxyeicosapentaenoic acid (AA) to washed human platelets induced conversion of EPA to TXB3 and 12-HEPE. Esculetin, a specific inhibitor of 12-lipoxygenase, prevented the effect of AA, but cyclooxygenase inhibitor did not. The conversion of AA to TXB2 was not affected by the same dose of esculetin. These data suggest that products of AA formed by 12-lipoxygenase in human platelets have stimulatory effects on EPA metabolism. When AA was preincubated with washed human platelets, its effect on EPA conversion was reduced, suggesting that a labile product of AA formed by 12-lipoxygenase is involved in the facilitation of EPA metabolism. Addition of 12-hydroperoxyeicosatetraenoic acid directly to washed human platelets caused dose-dependent synthesis of TXB3 and 12-HEPE, while addition of 12-hydroxyeicosatetraenoic acid had no effect. Thus, 12-hydroperoxyeicosatetraenoic acid formed from AA promotes the metabolism of EPA in washed human platelets.

Effects of water saturation and salinity on particle crushing of single coral sand (2023)

To evaluate the effects of particle size, water saturation and salinity on the mechanical properties of coral particles, single particle crushing tests were performed on 366 dried and saturated coral particles with varying sizes under different solution salinities. The AE energy release during particle breakage was monitored along with the diametrical compression loading. The results indicate that the increase in particle size and solution salinity decreases the particle crushing strength and increases its variability. The descending tendency in size-dependent crushing strength is attenuated by water saturation, causing more reduction in tensile strength for smaller particles than for larger ones. The breakage of single coral particles may be categorized into four typical patterns, predominated by the “Angularity fracture” and “Uniform failure” patterns. The AE features are distinctly different in the progressive failure of coral particles. The majority of the AE activities originate from frictional sliding, crack initiation and propagation.
Revisiting Keteniminium Salts: More than the Nitrogen Analogs of Ketenes (2011)

Keteniminium salts are powerful electrophilic heterocumulene reagents well-known for their selectivity and stereocontrol in [2+2] cycloadditions to olefins and carbonyl derivatives. Furthermore, they are readily accessible from stable and simple precursors under a variety of different conditions. Herein, we present the chemistry of keteniminium salts with the hindsight of time, describe preparation methods, recent [2+2] chemistry, mechanistic studies, and assorted applications that significantly extend the scope of utility of these unique electrophilic heterocumulenes.
Estimating the Relative Speed of RF Jammers in VANETs (2019)

Vehicular Ad Hoc Networks (VANETs) aim at enhancing road safety and providing a comfortable driving environment by delivering early warning and infotainment messages to the drivers. Jamming attacks, however, pose a significant threat to their performance. In this paper, we propose a novel Relative Speed Estimation Algorithm (RSEA) of a moving vehicle that approaches a transmitter (Tx)-receiver (Rx) pair that interferes with their radio frequency (RF) communication by conducting a denial of service (DoS) attack. Our scheme is completely passive and uses a pilot-based received signal without hardware or computational cost to, firstly, estimate the combined channel between the transmitter-receiver and jammer-receiver and, secondly, to estimate the jamming signal and the relative speed between the jammer-receiver using the RF Doppler shift. Moreover, the relative speed metric exploits the angle of projection (AOP) of the speed vector of the jammer in the axis of its motion in order to form a two-dimensional representation of the geographical area. Our approach can effectively be applied for any form of the jamming signal and is proven to have quite accurate performance, with a mean absolute error (MAE) value of approximately 10% compared to the optimal zero MAE value under different jamming attack scenarios. © 2019 Dimitrios Kosmanos et al.
Study on Garbage Collection Schemes for Flash-Based Linux Swap System (2008)

NAND flash memory based SSDs (solid state disks) have become an alternative storage device for future computer systems. Legacy operating system functionalities like file system and virtual memory system should be carefully re-designed since flash memory cannot be overwritten unless erased in advance. In this paper, we study the performance of garbage collection schemes when flash memory is used as the Linux swap storage. We have collected swap I/O traces from Linux kernel and performed trace-driven simulation. We found that Linux swap system must be re-designed in order to use flash memory as swap storage.
Promoting Action Research and Problem Solving among Teacher Candidates: One Elementary School's Journey (2006)

Abstract One elementary school's ongoing process in developing an appropriate action research requirement for teacher candidates during their student teaching experience (internship) is described. The assignment has evolved from a pilot project with one intern and mentor teacher to a requirement for all interns at the school. Several issues that emerged over time are addressed. These include encouragement of a problem-solving or inquiry stance that facilitates a focus on teacher candidates' impact on their students, the role of systematic data collection and analysis, ensuring ownership by the interns, and generalization of the problem-solving process from one project to other situations.
