Generating streamflow data at multiple sites using a monthly rainfall-runoff transformation (2000)

Synthetic simulations of multi-site streamflow data are used for drought risk assessments of large urban water supply systems. Typically the synthetic data are generated at monthly time scales. The multi-site hidden state Markov (HSM) model provides simulations of long-term annual rainfall values. Thus the work presented here develops a monthly rainfall-runoff transformation to generate long-term streamflow time series from the HSM simulated rainfall data. Given this transformation will inherently be fraught with error the emphasis was placed on ensuring the errors in the runoff were correctly modelled. Monthly rainfall-runoff data from five catchments within the Hawkesbury-Neapen River basin, near Sydney, Australia was used in this study. Given the shortcomings in the data a simple approach, the MONthly Gross Runoff Estimation model (MONGREL) was developed. The MONGREL captures the dominant physical processes that occur at monthly time scales with a minimum number of model parameters. For the two larger catchments a calibrated MONGREL using an appropriate error model structure was able to satisfactorily reproduce the observed runoff distributions at various long-term time scales. For three other smaller catchments the results were not quite as good arid could only be considered adequate. The insight gained from this study is that there is a clear need for a calibration framework which can adequately cope with errors in the hydrological data.
How to increase citizen coproduction: replication and extension of existing research (2018)

The value of coproduction—the joint productive efforts by regular producers, such as teachers, and consumer producers, such as parents, in helping children to learn—has been recognized for some time. However, strong empirical evidence of how these benefits can be achieved is scarce, and recent research has found mixed results. A new randomized field trial replicates elements of previous studies and extends them by using an additional age-appropriate outcome measure. Methodologically, the results illustrate the challenges of carrying out replication studies because when target groups change, outcome measures also often change. Substantially, the findings suggest that a government initiative providing parents with materials and information to enhance parents’ coproduction efforts can be extended to a broader target group of parents. Together, the findings illustrate how findings from single studies should be generalized with caution and the value of working systematically with replications and extensions.
Fluid characterisation and drop impact in inkjet printing for organic semiconductor devices (2011)

An inkjet printer can deposit a very small volume of liquid with high positional accuracy, high speed and low cost. As a maskless, non-contact additive patterning method, inkjet printing technology is increasingly being explored as an alternative to lithography, etching and vapour deposition processes to pattern electrical conductors and thin films with applications in printed electronic devices. The functional inks used in many of the applications involve non-linear viscoelasticity and their behaviours in the context of inkjet printing have not been fully understood. This thesis aims to characterise Newtonian and non-Newtonian properties of inkjet fluids and identify the key parameters affecting drop impact and spreading processes. Various fluid characterisation techniques such as the filament stretching rheometer and piezoelectric axial vibrator are explored. We propose an experimental method to assess the jettability of non-Newtonian inkjet fluids, without using an inkjet print head. The oblique collision of two continuous liquid jets leads to the formation of a thin oval liquid sheet bounded by a thicker rim which disintegrates into ligaments and droplets. Under certain conditions the flow structure exhibits a remarkably symmetrical “fishbone” pattern composed of a regular succession of longitudinal ligaments and droplets. Good correlation was found between the maximum included angle of the fishbone pattern and the maximum ligament length in the jetting experiments, which suggests that a test based on oblique impinging jets may be useful in the development of fluids for ink jet printing. High-speed imaging is used to analyse the impact and spreading of sub-30 μm drops of diethyl phthalate or polystyrene solutions in diethyl phthalate on to smooth glass surfaces with controlled wettability at speeds from 3 to 8 m s-1, under conditions representative of drop-on-demand inkjet printing. Data on drop height and spreading diameter are generated with high time and spatial resolution, over eight orders of magnitude in timescale. The effects of fluid viscosity and elasticity, which significantly affect jetting performance, are negligible throughout the whole deposition process, with no significant difference between spreading curves. The values of the fluid surface tension and the substrate wettability also have no effect on the kinematic, spreading or relaxation phases, but a marked influence on the wetting phase, in terms of the speed of expansion of the contact diameter and the final spreading factor.
Keeping healthy! Whose responsibility is it anyway? Vietnamese Canadian women and their healthcare providers’ perspectives (2007)

Understanding how healthcare responsibility is distributed will give insight on how health-care is delivered and how members of a society are expected to practice health-care. The raising cost of health-care has resulted in restructuring of the existing Canadian healthcare system toward a system that controls costs by placing more healthcare responsibility on the individual. This shift might create more difficulty for immigrants and refugees to obtain equitable health-care and put blame on them when they experience illness. This paper is drawn from the results of a larger qualitative study exploring Vietnamese Canadian women's breast cancer and cervical cancer screening practices. Interview data were gathered from 15 Vietnamese Canadian women and six healthcare providers. We will demonstrate that (a) despite the strong influence of individualism, Vietnamese women and their healthcare providers value both individual liberty and the interrelationship between individual and society; (b) limited funding and unequal distribution of healthcare resources impacted how immigrant and refugee women practice health-care. Thus, motivating and fostering immigrant and refugee women's healthcare practice require both individual and institutional effort. To foster immigrant and refugees' healthcare practices, healthcare policy makers and providers need to consider how to distribute healthcare resources that meet immigrants' and refugees' healthcare needs in the most equitable way.
Efficient back-bias generator with cross-coupledhybrid pumpingcircuit for sub-1.5 V DRAMs (2000)

A very efficient back-bias generator with cross-coupled hybrid pumping circuit (CHPC) is presented. Though the CHPC is based on the previously suggested hybrid pumping circuit (HPC), its cross-coupled nature which can totally eliminate the sacrificial voltage loss in storing the supply voltage (VCC) at the capacitor shows a much better pumping efficiency and increased pumping current over the HPC for VCC ranging from 3.3 to 0.9 V.
A User-Interface Robot for Ambient Intelligent Environments (2003)

This paper reports on the development of a domestic user-interface robot that is able to have natural human interaction by speech and emotional feedback. Natural interaction with the user is achieved by means of a mechanical head able to express emotions. Additionally, our robot is aware not only of its position in the environment but also of the position and intentions of the users. The localization of the robot is achieved with an appearance-based localization method. To get information about the users, the robot is designed to operate in (and to cooperate with) an intelligent ambient that takes care of monitoring the users. The result is a service robot that departs from existing developments in the fields of interface and service robots that are mainly reactive and, thus, limited in functionality. 1
Efficiency of bone ablation with a Nd:Yag laser beam delivered with a cooling spray: an in-vitro study (1993)

The purpose of our study was to determine the efficiency of bone ablation and the thermal damage caused by a Nd:YAG pulsed laser beam having an experimental cooling irrigation system.
Calibrating Histograms with Application to Economic Data (1989)

In this paper the problem of automatic calibration of histograms by cross-validation is considered, assuming the true underlying density is continuous with continuous first derivative. The histogram is one of the simpliest semiparametric estimators used by economists, but it is surprisingly difficult to construct histograms with small estimation errors. Cross-validation algorithms attempt, to automatically determine histogram bin widths that are nearly optimal with respect to mean integrated squared error. Alternative philosophies and approaches of cross-validation for histograms are presented. It is shown that the classical Sturges’ rule performs poorly and that cross-validation is a relatively difficult task. Understanding the performance of cross-validation algorithms in this simple setting should prove valuable when cross-validating other more complex semiparametric procedures.
TWO NONEXCLUSIVE NEURO-FUZZY CLASSIFIERS FOR RECOGNITION OF MUSICAL INSTRUMENTS (2015)

The classification of single musical sources is an essential step in order to obtain the source separation and the automatic transcription of polyphonic music. In this paper, we present a first experience of recognition of five different musical instruments (clarinet, flute, oboe, saxophone and violin). For such task, a nonexclusive classifier capable of fuzzy decisions is especially suitable, due to the inevitable overlaps among data. We used two different neuro-fuzzy classifier for recognition of musical instruments and we compared the obtained results. 1

The essential role of microsomal deacetylase activity in the metabolic activation, DNA-(deoxyguanosin-8-yl)-2-aminofluorene adduct formation and initiation of liver tumors by <i>N</i>-hydroxy-2-acetylaminofluorene in the livers of infant male B6C3F<sub>1</sub> mice (1988)

Deacetylation of N-hydroxy-2-acetylaminofluorene (N-hydroxy-AAF) to N-hydroxy-2-aminofluorene (N-hydroxy-AF) has been proposed as one of the critical metabolic steps in the formation of hepatic DNA adducts and the initiation of liver tumors in 12-day-old male B6C3F1 mice. In this study, the importance of the microsomal deacetylase activity for N-hydroxy-AAF in the initiation of hepatocarcinogenesis in these mice was demonstrated by using a carboxylesterase and amidase inhibitor, bis(p-nitrophenyl)phosphate (BNPP), that is much less toxic in vivo than is paraoxon. Pre-incubation of liver microsomes from 12-day-old male B6C3F1 mice with 10(-3) M BNPP reduced the deacetylase activity by 80% while paraoxon inhibited the deacetylase activity completely at a concentration of 10(-4) M. Pretreatment of 12-day-old male B6C3F1 mice with 4 X 75 micrograms doses of BNPP/g body weight before the administration of N-hydroxy-AAF reduced the hepatic N-(dGuo-8-yl)-AF adduct levels to 1.09 and 0.68 pmol/mg DNA compared with 2.87 and 1.64 pmol/mg DNA for mice treated once with 0.06 or 0.03 mumol of N-hydroxy-AAF/g body weight respectively. However, BNPP pretreatments did not affect the levels of the acetylated DNA adducts, N-(dGuo-8-yl)-AAF and 3-(dGuo-N2-yl)-AAF, formed by these doses of N-hydroxy-AAF. The initiation of liver tumors by N-hydroxy-AAF was also inhibited by BNPP pretreatment. Thus, for mice that received single doses of 0.12, 0.06 and 0.03 mumol of N-hydroxy-AAF/g body weight, the multiplicities of liver tumors at 10 months were reduced by BNPP pretreatments to 5.6, 1.0 and 0.3 compared with multiplicities of 11.8, 4.8 and 1.7 without pretreatment respectively. On the other hand, BNPP pretreatments had no significant inhibitory effects on the levels of the hepatic DNA-N-(dGuo-8-yl)-AF adduct or on the liver tumor multiplicities induced by comparable doses of N-hydroxy-AF. It is concluded that deacetylation of N-hydroxy-AAF to N-hydroxy-AF is essential for the metabolic activation, DNA-N-(dGuo-8-yl)-AF adduct formation and liver tumor initiation in infant male B6C3F1 mice by N-hydroxy-AAF.
Dynamic delta modeling (2012)

Abstract Delta Modeling (ADM) offers an algebraic description of how a (software) product line may be built so that every product can be automatically derived by structured reuse of code. In traditional application engineering a single valid feature configuration is chosen, which does not change during the lifetime of the product. However, there are many useful applications for product lines that change their configuration at run time. We present a new technique for generating efficient dynamic product lines from their static counterparts. We use Mealy machines for their dynamic reconfiguration. Furthermore, we posit that monitoring some features will be more expensive than monitoring others, and present techniques for minimizing the cost of monitoring the system. We stay in the abstract setting of ADM but the techniques can be instantiated to any concrete domain. We illustrate them through the example of a mobile application for Android, which dynamically reconfigures a devices operating profile based on environmental factors.
Dimerization of Flavivirus NS4B Protein (2014)

The reported expression and purification system has made it possible to study the biochemistry and structure of flavivirus NS4B proteins. The finding of flavivirus NS4B dimerization and the mapping of regions important for NS4B dimerization provide the possibility to inhibit viral replication through blocking NS4B dimerization. The requirement of NS4B in the context of the replication complex for successful trans-complementation enhances our understanding of NS4B in flavivirus replication.
Rateless Slepian-Wolf Coding Based on Rate Adaptive Low-Density-Parity-Check Codes (2007)

A rateless Slepian-Wolf coding (SWC) scheme based on rate adaptive low-density-parity-check (LDPC) codes is presented. We first motivate the application of punctured LDPC codes in SWC. A general rate adaptive LDPC framework is then described. The main idea is to adjust the puncturing ratio in the specified variable nodes for rate adaptivity while keeping the bipartite graph structure intact. As a complement, a repetition scheme is proposed for high rate SWC. The asymptotic performance of the proposed scheme is analyzed by density evolution (DE) with universal coding bounds and finite code length performance is verified by computer simulations.
Inductively Coupled Plasma-Atomic Emission Spectroscopy: An Alternative Approach to “Flameless” Atomic Absorption Spectroscopy (1977)

Atomic emission spectroscopy (AES) combined with an inductively coupled plasma (ICP) excitation source is discussed as an attractive alternative approach to “flameless” atomic absorption spectroscopy for the determination of trace elements in liquid samples of limited volume. The AES-ICP approach offers the potential advantage of: (a) being able to perform these determinations on a simultaneous multielement basis, and (b) possessing an unusual degree of freedom from interelement effects if solution nebulization techniques are utilized. For 1-ml sample volumes, the relative powers of detection (ng/ml) of the AES-ICP approach are comparable to the values reported for flameless atomic absorption procedures.
Decentralized Resource Allocation Mechanisms in Networks: Realization and Implementation (2006)

We discuss how decentralized network resource allocation problems fit within the context of mechanism design (realization theory and implementation theory), and how mechanism design can provide useful insight into the nature of decentralized network resource allocation problems. The discussion is guided by the unicast problem with routing and Quality of Service (QoS) requirements, and the multi-rate multicast service provisioning problem in networks. For these problems we present decentralized resource allocation mechanisms that achieve the solution of the corresponding centralized resource allocation problem and are informationally efficient. We show how the aforementioned mechanisms can be embedded into the general framework of realization theory, and indicate how realization theory can be used to establish the mechanisms’ informational efficiency in certain instances. We also present a conjecture related to implementation in Nash equilibria of the optimal centralized solution of the unicast service provisioning problem.
Comparative Study: Location Based Mobile Advertisement Publishing System (2015)

In recent years, mainly advertisements and vouchers are used for providing discounts, text messages and posters were mainly used till date but to advertise on a mobile device is need of the current scenario. Vendors must be allowed to publish and edit an advertisement to users according to the interest of the customer. This technique has low cost for digital advertisement and has a pervasive system for advertising in large commercial malls. In order to publish advertisements on customer mobile phones and find the desired location of the vendors, QR codes are used. Location and deals can be obtained on the customer's mobile phone by scanning the QR code on the mobile phone. In this paper, survey on various location based system and different techniques for publishing advertisement is done.
Representation of movements and muscles within the primate precentral motor cortex: historical and current perspectives. (1986)

A major problem with the study of the control of movement and posture is to determine how specific brain areas contribute to the selection of those particular muscle patterns that underlie a coordinated movement. With this problem in mind, a selective review is presented of mapping studies of the primate motor cortex, whose results bear on the question of how the spatial organization of cortical efferent cells might contribute to the production of organized muscle synergies. More recent findings are also summarized, which appear to resolve previous controversies on the question of whether movements or muscles are the primary units of motor cortex organization. These same findings suggest also a form of spatial organization within the primate precentral gyrus that would allow spatially simple afferent inputs to evoke the muscle synergies that are necessary for a variety of simple movements of the arm and hand.
A Negative-Grid Triode Oscillator and Amplifier for Ultra-High Frequencies* (1937)

The author describes three negative-grid triodes of unusual design which operate both as oscillators and as amplifiers at ultra-high frequencies. The power output of the smallest tube as an oscillator at 1500 megacycles is 2 watts, and is still capable of an output of 1 watt at 1700 megacycles with an oscillation limit of 1870 megacycles corresponding to a wave-length of 16 centimeters. This tube also offers possibilities as an amplifier at frequencies as high as 1000 megacycles. Such capabilities of the negative-grid triode are notable since this device has appeared to lag behind the magnetron as an oscillator at fre-quencies of above roughly 500 megacycles, while the only successful power amplifiers which have been described for frequencies of the order of 300 megacycles are multi-element tubes.
Array of Fundamental Torsional Mode EMATs and Experiment in Thick-wall Pipe with Small Diameter (2015)

Pipe inspection is an important issue from the perspective of power plant thermal equipment safety. It is difficult to inspect pipe with the conventional non-destructive methods, because of a high temperature and a limited accessibility in the region. The fundamental torsional guided wave is very effective for long range crack of pipe inspection, because of its non-dispersive characteristics. In order to generate non-contact T(0,1) mode, array of fundamental torsional mode electromagnetic acoustic transducers(EMATs) is designed and developed. Using the transducer, T(0,1) mode is generated and detected in the thick-wall pipe with small diameter. By optimizing the element connections of array of EMATs, when the elements are connected in parallel, the generated signal energy not only can be improved, but also other modes can be inhibited. Meanwhile, the frequency response characteristic is tested and the artificial defect along the circumferential direction of the sample pipe is detected. The transducer can achieve identification and accurate location of crack in the circumferential direction of the sample pipe. This proposed method provides a certain foundation for generation and detection T(0,1) mode and non-contact detection of cracks in the pipe.
A novel Gfer-Drp1 link in preserving mitochondrial dynamics and function in pluripotent stem cells (2010)

AbstractMitochondria, the dynamic energy powerhouses of the cell, have vital roles in a multitude of cellular processes including differentiation and cell survival. Tight regulation of mitochondrial dynamics, integrity, and function is indispensible for preservation of homeostasis in all cells, including pluripotent stem cells. The ability to proliferate and self-renew indefinitely bestows the pluripotent embryonic stem cells (ESCs) with immense curative potential. Mechanisms that preserve mitochondrial well-being, and therefore maintain "stemness", are vital in realizing the full potential of ESCs in therapeutic regenerative medicine. However, virtually nothing is known regarding the regulation of mitochondrial dynamics and function and the relationship thereof to overall cell fate and function in pluripotent ESCs or other somatic stem cells. Using loss- and gain-of-function approaches, we show that growth factor erv1-like (Gfer) plays an essential pro-survival role in the maintenance of murine ESC pluripotency by preserving the structural and functional integrity of their mitochondria, through modulation of the key mitochondrial fission factor Drp1.This article refers to:
