Synergistic effect of a novel oxymatrine-baicalin combination against hepatitis B virus replication, alpha smooth muscle actin expression and type I collagen synthesis in vitro. (2006)

OB combination has a better effect against HBV replication in 2.2.15 cells and is more effective against alpha SMA expression and type I collagen synthesis in HSC-T6 cells than oxymatrine in vitro.
Predicting Extractives, Lignin, and Cellulose Contents Using Near Infrared Spectroscopy on Solid Wood in<i>Eucalyptus globulus</i> (2006)

Near infrared reflectance (NIR) spectroscopy can be used to reliably predict both the physical and chemical wood properties of Eucalyptus. However, studies have been based on ground wood, which is costly and time-consuming to obtain. Predicting wood traits from NIR spectral data taken from solid wood would greatly increase the speed and cost-effectiveness of this procedure. Existing ground wood calibrations were evaluated for the prediction of wood chemistry from NIR spectral data taken from solid wood. Extractives, acid-soluble lignin, and Klason lignin contents were poorly predicted. Total lignin and cellulose contents showed moderate relationships between laboratory values and the NIR predicted values. NIR calibrations were further developed specifically for predicting wood chemistry from solid wood. All calibrations had high R2 values from 0.72 to 0.88, and standard errors of calibration were less than 1.37%. Calibration validation produced high correlation coefficients between predicted and laboratory values for extractives, Klason lignin, total lignin, and cellulose contents with R2 values ranging from 0.67 to 0.87. Acid-soluble lignin content was poorly predicted. This study showed that NIR analysis on solid wood of E. globulus could be reliably used to predict extractives, lignin, and cellulose contents. It also determined that existing ground wood calibrations, although they could give crude estimates of the wood chemistry values, would need to be re-developed for accurate predictions from solid wood.

Augmented Worlds: a proposal for modelling and engineering pervasive mixed reality smart environments (2019)

In recent years, the remarkable technological advancement has revolutionised the ICT panorama offering nowadays the opportunity to exploit several technological convergences to reduce the gulf existing between the physical and the digital matter, between the physical real world and every computational software system or application. Along with Pervasive Computing - entered in the mainstream with the concept of Internet of Things (IoT) - Mixed Reality (MR) is going to be an essential ingredient for the design and development of next future smart environments. In particular, in such environments is feasible to imagine that the computation will drive the augmentation of the physical space, and software will also be executed in a cyber-physical world, eventually populated with of (interactive) holograms. \n\nAfter an initial exploration of the state of the art about augmentation technologies both for humans and the environment, in this dissertation we present the vision of Augmented Worlds (AW), a conceptual and a practical proposal for modelling and engineering next future pervasive mixed reality smart environments as distribute, multi-user and cooperative complex software systems.\nOn the one hand, a meta-model is formalised and opportunely discussed to offer to the literature a conceptual tool for modelling AWs. On the other hand, also a concrete infrastructure - called MiRAgE - is designed and developed to produce a platform for engineering and deploy such innovative smart environments.\n\nThe work carried out in this dissertation fits into the scientific literature and research of Pervasive Computing and Mixed Reality fields. Furthermore, part of the contribution is related also to the area of Cognitive Agents and Multi-Agent Systems, due to the AWs orientation to be deeply connected to a layer involving autonomous agents able to observe and act proactively in the smart environment.
INTRACAVITY LASER ABSORPTION SPECTROSCOPY USING QUANTUM CASCADE LASER AND FABRY-PEROT INTERFEROMETER (2011)

Intracavity Laser Absorption Spectroscopy (ICLAS) at IR wavelengths offers an opportunity for spectral sensing of low vapor pressure compounds. We report here an ICLAS system design based on a quantum cascade laser (QCL) at THz (69.9 m) and IR wavelengths (9.38 and 8.1 m) with an open external cavity. The sensitivity of such a system is potentially very high due to extraordinarily long effective optical paths that can be achieved in an active cavity. Sensitivity estimation by numerical solution of the laser rate equations for the THz QCL ICLAS system is determined. Experimental development of the external cavity QCL is demonstrated for the two IR wavelengths, as supported by appearance of fine mode structure in the laser spectrum. The 8.1 m wavelength exhibits a dramatic change in the output spectrum caused by the weak intracavity absorption of acetone. Numerical solution of the laser rate equations yields a sensitivity estimation of acetone partial pressure of 165 mTorr corresponding to ~ 200 ppm. The system is also found sensitive to the humidity in the laboratory air with an absorption coefficient of just 3 x 10-7 cm -1 indicating a sensitivity of 111 ppm. Reported also is the design of a compact integrated data acquisition and control system. Potential applications include military and commercial sensing for threat compounds such as explosives, chemical gases, biological aerosols, drugs, banned or invasive organisms, bio-medical breath analysis, and terrestrial or planetary atmospheric science.
Adaptive learning of teleoperating robotic motion (2002)

In this paper, we propose a method of adaptive learning control applicable to the bilaterally controlled teleoperating system. The control scheme learns the desired inverse dynamics of the system to predict and compensate for the nonlinear dynamics which is the source of poor trajectory tracking and force regulation. In addition, the uncertain system parameters and input disturbances are continuously learned and the time-variance of which is also taken into account by the feedforward learning controller. The proposed control scheme is shown to be stable and the effectiveness of which is experimentally verified with a teleoperating system composed of master-slave SCARA robots.
Application of Support Vector Machines in Classification of Magnetic Resonance Images (2006)

The authors present an application of support vector machines in the classification of magnetic resonance images. Traditional classification methods, such as neural network approaches, have suffered difficulties with generalization, producing models that can overfit the data. The SVM approach is considered a good candidate because of its high generalization performance. At each location in 2D MR images, the SVM classifier is trained through supervised learning to determine which one of the three brain tissues (WM, GM, and CSF) and the background the pixel belongs to. The results are compared with convention methods in terms of the average computational time and the classification error rate. The comparative experiment results demonstrate that the SVM method achieves very good performance with 9.89% classification error rate and 6.18 seconds total time, compared with 11.65% and 173.51 seconds by the FCM and 12.22% and 244.63 seconds by the BP MLP. The ability of SVM to outperform the BP-MLP and the FCM suggests that SVM is a promising technique in classification of MR images.

Synthesis and co-ordination chemistry of 1,7-bis(carboxymethyl)-4,10-bis(1-methylimidazol-2-ylmethyl)-1,4,7,10-tetraazacyclododecane (1998)

The potentially octadentate ligand 1,7-bis(carboxymethyl)-4,10-bis(1-methylimidazol-2-ylmethyl)-1,4,7,10-tetraazacyclododecane (H2L), which contains two oxygen and two nitrogen donors on the groups attached to the macrocycle, has been isolated and characterized as the pentahydro-bromide or -perchlorate, H2L·5HY (Y = Br or ClO4). Its co-ordination chemistry towards nickel(II) and zinc(II) ions has been investigated and the structures of the complexes which have been obtained, [NiL]·6.5H2O 1, [Ni(H1.5L)][ClO4]1.5·2H2O 2 and [Zn3L2][ClO4]2·5H2O 3, have been determined by single-crystal X-ray analyses. The metal ion in 1 and 2 is in an approximately octahedral environment formed by the four nitrogen donors of the macrocycle and two donors from the dangling groups, either carboxyl oxygens 1 or methylimidazole nitrogens 2. In the trimetallic zinc complex two metal ions, in peripheral positions, are seven-co-ordinated, whereas the third is tetrahedrally four-co-ordinated.

Histone code pathway involving H3 S28 phosphorylation and K27 acetylation activates transcription and antagonizes polycomb silencing (2011)

Histone H3 phosphorylation is a critical step that couples signal transduction pathways to gene regulation. To specifically assess the transcriptional regulatory functions of H3 phosphorylation, we developed an in vivo targeting approach and found that the H3 kinase MSK1 is a direct and potent transcriptional activator. Targeting of this H3 kinase to the endogenous c-fos promoter is sufficient to activate its expression without the need of upstream signaling. Moreover, targeting MSK1 to the α-globin promoter induces H3 S28 phosphorylation and reactivates expression of this polycomb-silenced gene. Importantly, we discovered a mechanism whereby H3 S28 phosphorylation not only displaces binding of the polycomb-repressive complexes, but it also induces a methyl-acetylation switch of the adjacent K27 residue. Our findings show that signal transduction activation can directly regulate polycomb silencing through a specific histone code-mediated mechanism.
Role of the glutamine transaminase- -amidase pathway and glutaminase in glutamine degradation in Rhizobium etli (1995)

Summary Evidence for the participation of the glutamine transaminase-ω-amidase pathway and a glutaminase in the utilization of glutamine in Rhizobium etli has been obtained. The glutamine transaminase preferentially transaminates glyoxylate and pyruvate. Glutamine transaminase activity was similar under all growth conditions tested except on PY (rich medium) where it was low. Glutaminase activity was positively regulated by glutamine and negatively regulated by ammonium and by the carbon source. In R. etli bacteroids, glutamine transaminase was low, whereas glutaminase activity was high. Ammonium liberated from glutamine was assimilated by glutamine synthase, thus leading to the operation of a glutamine cycle that consumes ATP. Our results suggest that glutamine transaminase plays a biosynthetic role in the irreversible synthesis of glycine and alanine, whereas glutaminase plays a catabolic role in the degradation of glutamine to carbon skeletons and to maintain the optimal balance between glutamine and glutamate. The high glutaminase activity found in bacteroids indicates that the degradation of glutamine by this enzyme may play an important role during symbiosis between R. etli and Phaseolus vulgaris.
New Priorities for Philanthropy (2002)

The events of September 11 have forced institutions to reexamine their priorities and practices. Yet the first world war of the twenty-first century has left many wondering if there truly is a war, and what, if anything, different is demanded of them. The philanthropic sector in particular has not changed significantly, and it continues to struggle with fundamental concerns about its directions. If September 11 and its aftermath are to mean anything to philanthropy other than emergency relief, it must be a recognition that now is the time to tackle the problems and tensions that were ignored before the attacks. For nearly a year, philanthropy as a sector has not rallied behind this call for longer-term reform. Philanthropy should take up these tasks, no matter how daunting they may be, for if foundations do not lead the effort, it may be left to the governments and the militaries of the world to respond on their own.
A breeding program to reduce the diameter of the major xylem vessel in the seminal roots of wheat and its effect on grain yield in rain-fed environments (1989)

It is thought that the man xylem vessel in the seminal roots of wheat crop will regulate crop water use if water is available in the subsoil but the top soil is dry. This should result in more water being used after anthesis, and a higher harvest index and yield. A backcross breeding program using two Australian commercial wheat varieties is described that reduced their xylem vessel diameter from about 65 8m to less than 55 8m. In field trials conducted on fallow land in eastern Australia over five years, comparing selections with narrow xylem vessels against unselected controls, narrow vessel selections yielded between 3 and 11% more than the unselected controls, depending upon their genetic background, in the driest environments. Yield differences in the wetter environments were largely not significant. This yield increase in the narrow vessel selections was associated with a significantly higher harvest index, also higher biomass at maturity and kernel number.

Susceptibility of Plasmodium falciparum to five drugs: an in vitro study of isolates mainly from Thailand (1983)

This paper describes the results of testing the susceptibility of 60 isolates of the human malaria parasite Plasmodium falciparum from Thailand, and single isolates from five other countries, to five drugs: chloroquine, pyrimethamine, quinine, mefloquine and amodiaquine. The Thai isolates were obtained from patients in three different regions of the country (Chantaburi, Songkhla and Mae Sod), and were first grown in culture by the Trager-Jensen candle-jar technique. Samples were then exposed to a range of concentrations of the five drugs, in Falcon microtest culture wells, for 72 hours, with daily changes of medium (with or without added drug solutions). Presence or absence of parasites was then determined by microscope observations on thin-film Giemsa-stained preparations. Most Thai isolates showed a minimum inhibitory concentration (MIC) for chloroquine of 10(-6) M or higher, and were classified as highly resistant, though one cloned isolate was as sensitive to this drug as a chloroquine-sensitive isolate from West Africa. Similarly most Thai isolates showed a very high resistance to pyrimethamine (MIC 10(-4) M to 10(-6) M), but a few clones were sensitive (MIC 10(-9)) to it. Susceptibility to quinine showed some variation (MIC varied between 10(-6) M and 10(-8) M), and some isolates were thought to be incapable of responding to a therapeutically permissible dose of this drug. Little variation was found in the reaction of any of the isolates to mefloquine or amodiaquine, and by the in vitro technique used in this study, it was found that chloroquine-resistant and chloroquine-sensitive isolates were equally susceptible to amodiaquine. In general the survey showed the existence of a marked correlation between development of drug resistance of Plasmodium falciparum and the extent to which a given drug had been used in Thailand.
Security risk metrics: fusing enterprise objectives and vulnerabilities (2005)

Automated scanners are unable to generate the information required to properly assess a network's risk. Although scanners may identify high risk exposures, they fail to determine how those exposures affect an organization's objectives. Such an assessment requires an auditor to identify the objectives and their relationship to network hosts. Mission trees allow security auditors to map relationships between an organization's objectives and its assets. Synthesizing this data with a vulnerability scanner lends itself to creating meaningful enterprise security metrics.
Design Considerations of Resonant Network and Transformer Magnetics for High Frequency LLC Resonant Converter (2016)

This paper proposes the design considerations of resonant network and transformer magnetics for 500 kHz high switching frequency LLC resonant converter. The high power density can be effectively achieved by adopting high switching frequency which allows small size passive components in the converter. The design methodology of magnetizing inductance is derived for zero voltage switching (ZVS) condition, and the design methodology of the transformer and output capacitance is derived to achieve high power density at high operating frequency. Moreover, the structure of transformer is analyzed to obtain the proper inductance value for high switching operation. To verify the proposed design methodology, simulation and experimental results will be presented including temperature of passive and active components, and power conversion efficiency to evaluate dominant power loss. In addition, the validity of magnetics design will be evaluated with operating waveforms of the prototype converter.
Integrated OBD-II and mobile application for electric vehicle (EV) monitoring system (2017)

Electric Vehicles (EV) are becoming more popular, advanced and connected to the internet, the users are being encouraged to use new technologies for tracking, monitoring and controlling their EVs. The experienced users tend to monitor and control specific EV parts including ABS, Airbag, and Air Condition easily and seamlessly. Currently, there is no a distinct system at all that would integrate all these factors into one disposable application. This research develops a system which communicates with On Board Diagnostics of Electric Vehicle by using Controller Area Network communication protocol. The paper discusses how to collect CAN data by new and low-cost method through OBD-II port. The OBD-II is traditionally used by technicians for reading fault codes and monitoring the actual value of each connected control units. There are few other solutions already available, but none of them satisfies requirements for experienced users. Ordinarily, these available solutions can be applied for monitoring the state of charge and battery parameters. The extraction of all the available data in EV CAN network has been done systematically through OBD-II port and by using low-level software libraries and programming a development board based on ARM STM32F103RBT6 micro-controller. This paper discuss an implementation an integrated OBD-II system for monitoring CAN data such as SOC and Energy consumption based on Android. Finally, the CAN data (e.g., lock and unlock door and Air condition control) will be injected in EV CANs system. Overall, the proposed approach can facilitate the monitoring and control processes for most of specific EV parts considering flexibility and ease of use for the end users.
High quality video on multimedia PCs (2003)

Displaying broadcast video on a multimedia PC, implies the use of video format conversion (VFC) techniques, as computer displays and television receivers use quite distinct scanning rasters. VFC consists of spatial scaling, deinterlacing and picture rate conversion. Although scaling is rather straightforward, the other two tasks are far from trivial, and advanced motion compensated interpolation techniques are necessary to achieve a performance level that can compete with that of a standard TV. The paper discusses the options for picture rate conversion, and shows how even advanced motion compensated algorithms can run real time on a currently available programmable device.
A comparative study of sorption of water vapor by oligomeric triblock copolymers of ethylene and propylene oxides (1991)

Abstract Equilibrium sorption of water vapor by oligomeric block copolymers (PEP) of ethylene and propylene oxides was measured at 23°C at five values of the relative vapor pressure, 0.32 ≦ p / p 0 ≦ 0.90. Sorption isotherms were described by a simple empirical two‐parameter equation. The effect of the copolymer composition on the parameters was established. The Lundberg‐Zimm clustering function, the mean size of clusters of water molecules, and the Flory‐Huggins interaction parameters were estimated. Their dependencies on copolymer composition and water content in the system are discussed.
A highly-extensible, XML-based architecture description language (2002)

Software architecture research focuses on models of software architectures as specified in architecture description languages (ADLs). As research progresses in specific areas of software architectures, more and more architectural information is created. Ideally, this information can be stored in the model. An extensible modeling language is crucial to experimenting with and building tools for novel modeling constructs that arise from evolving research. Traditional ADLs typically support a small set of modeling constructs very well, but adapt to others poorly. XML provides an ideal platform upon which to develop an extensible modeling language for software architectures. Previous XML-based ADLs successfully leveraged XML's large base of off-the-shelf tool support, but did not take advantage of its extensibility. To give software architecture researchers more freedom to explore new possibilities and modeling techniques, while maximizing reuse of tools and modeling constructs, we have developed xADL 2.0, a highly extensible XML-based ADL. xADL 2.0 supports run-time and design time modeling, architecture configuration management and model-based system instantiation. Additionally, xADL 2.0 has a set of extensible infrastructure tools that support the creation, manipulation, and sharing of xADL 2.0 documents.
