Research and Development in Drying: Recent Trends and Future Prospects (2004)

Abstract Drying R&D has seen nearly exponential growth over the past three decades. Initially driven by the need to conserve energy in this highly energy-intensive operation found in almost all industrial sectors, now the focus is on product quality, environmental impact, safety issues, new products, and processes etc. Drying provides challenging areas for multi- and cross-disciplinary research of fundamental as well as applied nature coupling transport phenomena with material science. An attempt will be made to summarize the new developments in drying technologies, identify recent trends and make predictions about the future trends that may be expected. Also, personal perspectives on models of research appropriate for drying technology will be presented. The need for industry-academia interaction and for a stake of industry in academic research is noted as a key step towards successful transfer of innovative drying technologies to industry. Finally, the weaknesses of the currently popular “closed loop” approach of research in academia, by academia and for academia, resulting on over-emphasis on “high impact-factor” rather than “high impact research” will be discussed. It is hoped that future IDS meetings will increase industry participation by enhancing their impact on industrial adoption of newer more efficient drying technologies. It is essential to make it a worthwhile—even essential—exercise for industry to participate in these meetings.
Social Graph Generation &#x00026; Forecasting Using Social Network Mining (2009)

Considering the noticeable attraction of users to social networking sites, lots of research has been carried out to take advantage of the userspsila information available in these sites. Knowledge mining techniques have been developed in order to extract valuable pieces of information from the userspsila activities. This paper deals with a methodology to generate a social graph of userspsila actions and predict the future social activities of the users based upon the existing relationships. This graph is updated dynamically based on the changes in the selected social network. The forecasting performed is based upon some predefined rules applied on the graph.
Mutations in the <i>FASS</i> gene uncouple pattern formation and morphogenesis in <i>Arabidopsis</i> development (1994)

The pattern of cell division is very regular in Arabidopsis embryogenesis, enabling seedling structures to be traced back to groups of cells in the early embryo. Recessive mutations in the FASS gene alter the pattern of cell division from the zygote, without interfering with embryonic pattern formation: although no primordia of seedling structures can be recognised by morphological criteria at the early-heart stage, all elements of the body pattern are differentiated in the seedling. fass seedlings are strongly compressed in the apical-basal axis and enlarged circumferentially, notably in the hypocotyl. Depending on the width of the hypocotyl, fass seedlings may have up to three supernumerary cotyledons. fass mutants can develop into tiny adult plants with all parts, including floral organs, strongly compressed in their longitudinal axis. At the cellular level, fass mutations affect cell elongation and orientation of cell walls but do not interfere with cell polarity as evidenced by the unequal division of the zygote. The results suggest that the FASS gene is required for morphogenesis, i.e., oriented cell divisions and position-dependent cell shape changes generating body shape, but not for cell polarity which seems essential for pattern formation.
Evidence for spontaneous, reversible paracyclophane formation. Aprotic solution structure of the boron neutron capture therapy drug, L-p-boronophenylalanine (2000)

The simple, straightforward 1H NMR spectrum of the neutron capture therapy drug, L-p-boronophenylalanine (L-p-BPA), in D2O changes to a more complex one in DMSO-d6 in which the ratio of new species observed is highly concentration dependent. The new species detected can only be explained by an additional stereocenter being formed at the boron center by intermolecular chelation of the amino acid of another molecule of L-p-BPA. This gives rise to the presence of an oligomeric species as well as another whose aromatic protons appear as a pair of sharp AB quartets centered further upfield at 6.66 and 6.84. Due to these shifts and couplings observed between the benzylic protons and the proton at the stereocenter of the amino acid, it is proposed that this species is a paracyclophane dimer of L-p-BPA in which one molecule of L-p-BPA chelates head-to-tail with another. This cyclophane dimer predominates in low concentrations (<50 mM) while the oligomer predominates at higher (>90 mM) concentrations. The formation of these two species is completely reversible, the addition of D2O completely regenerating L-p-BPA. Variable temperature 1H NMR found that the two pairs of aromatic protons of the cyclophane dimer coalesce at Tc = 141 °C, corresponding to a ΔG‡ = 20.6 kcal mol−1.
Hydrogen nexus in a sustainable energy future (2008)

The vast majority of power/energy generation in our global economy is based on the chemical element carbon, specifically fossil carbon (coal) and hydrocarbon (oil and gas) fuels. Such an economy is not sustainable in the medium- to long-term for two fundamental reasons; first, there exists only a finite amount of fossil fuel, and, second, the carbon dioxide released during the combustion of fossil fuels induces anthropogenic climate change with costly and potentially disastrous consequences. Current energy technologies cannot support both a reduction in carbon dioxide emissions and an ever-expanding global economy. It is now recognized that hydrogen may be one of the leading contenders as a potential solution for a sustainable alternative to fossil fuels, especially for transport and for heat and power generation and energy storage. However, any transition from a carbon-based (fossil fuel) energy system to a hydrogen-based economy involves significant scientific, technological and socio-economic barriers. Our aim is to illustrate the “hydrogen nexus” as a possible connection or link from today's carbon economy to a sustainable energy future centred on hydrogen.
Elastographic imaging of thermally ablated tissue in vitro (2003)

Focused ultrasound surgery (FUS) is a promising therapeutic technique but progress is currently limited by the need for improved imaging methods to monitor the extent of tissue damage during and immediately after FUS exposure. Thermally ablated tissue are generally stiffer relative to surrounding undamaged tissues, which suggests that it should be possible to monitor FUS using any imaging technique, such as elastography, which is capable of visualising tissue elasticity. The aim of this paper is to report the results of a preliminary investigation conducted using ex-vivo bovine liver tissues, to explore the feasibility of monitoring FUS using ultrasonic elastographic imaging. The results demonstrated that spatial and contrast resolution of elastography should be sufficiently high for monitoring focused ultrasound surgery.
<i>Borrelia burgdorferi</i> Erp Proteins Are Immunogenic in Mammals Infected by Tick Bite, and Their Synthesis Is Inducible in Cultured Bacteria (1998)

Borrelia burgdorferi, the causative agent of Lyme disease, can contain multiple genes encoding different members of the Erp lipoprotein family. Some arthropod-borne bacteria increase the synthesis of proteins required for transmission or mammalian infection when cultures are shifted from cool, ambient air temperature to a warmer, blood temperature. We found that all of the erp genes known to be encoded by infectious isolate B31 were differentially expressed in culture after a change in temperature, with greater amounts of message being produced by bacteria shifted from 23 to 35 degrees C than in those maintained at 23 degrees C. Mice infected with B31 by tick bite produced antibodies that recognized each of the Erp proteins within 4 weeks of infection, suggesting that the Erp proteins are produced by the bacteria during the early stages of mammalian infection and may play roles in transmission from ticks to mammals. Several of the B31 Erp proteins were also recognized by antibodies from patients with Lyme disease and may prove to be useful antigens for diagnostic testing or as components of a protective vaccine.
Physical Modeling of Plucked String Instruments with Application to Real-Time Sound Synthesis (1996)

An efficient approach for real-time synthesis of plucked string instruments using physical modeling and DSP techniques is presented. Results of model-based resynthesis are illustrated to demonstrate that high-quality synthetic sounds of several string instruments can be generated using the proposed modeling principles. Real-time implementation using a signal processor is described, and several aspects of controlling physical models of plucked string instruments are studied.
Image‐based hysteresis modeling and compensation for an AFM piezo‐scanner (2009)

Abstract As an important component of Atomic Force Microscopes (AFM), a piezo‐scanner exhibits some undesired nonlinear characteristics, among which the inherent hysteresis largely decreases positioning accuracy during scanning and nano‐manipulation process. To alleviate this problem, an image‐based approach is proposed in this paper to model and then compensate for the hysteresis behavior of the piezo‐scanner. Specifically, some scanning images over standard samples are utilized to identify the parameters of the classical Preisach model (CPM) of hysteresis. On the basis of the obtained model, an inversion‐based technique is adopted to design a compensator for the hysteresis of the piezo‐scanner. The proposed algorithm presents such advantages as low cost and little complexity since no nanoscale position sensor is required to collect identification data. Some scanning and nano‐imprinting results are included to demonstrate the performance of the proposed strategy. Copyright © 2009 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
2,3-<i>O</i>-(3-Pentylidene)-D-glyceraldehyde and 2,3-<i>O</i>-(3-Pentylidene)-L-glyceraldehyde: Convenient Glyceraldehyde Surrogates Obtained via a Novel Periodate-Based Oxdation System (1992)

The synthesis of two novel glyceraldehyde surrogates, 2,3-O-(3-pentylidene)-D-glyceraldehyde (2) and 2,3-O-(3-pentylidene)-L.-glyceraldehyde (3) is presented. Synthesis, handling and storage advantages of 2 and 3 over the conventionally employed 2,3-O-isopropylidene-D-glyceraldehyde (1) are discussed. The 3-pentanone-derived protecting group facilitates the extraction of product from aqueous oxidation solutions, while the 3-pentanone liberated on ketal deprotection can be efficiently removed at reduced pressures. The synthesis employs a buffered potassium periodate oxidation which offers significant advantages over sodium periodate in glycol cleavage reactions.
Reciprocal-wedge transform for space-variant sensing (1995)

The reciprocal-wedge transform (RWT) is presented as an alternative to the log-polar transform which has been a popular model for space-variant sensing in computer vision. The RWT facilitates an anisotropic variable resolution. Unlike the log-polar, its variable resolution is predominantly in one dimension. Consequently, the RWT preserves linearity of lines and translations in the original image. In this paper, a concise matrix representation of the RWT is presented. Its properties in geometrical transformations and data reduction are described. A projective model for the transform and a potential hardware RWT camera design are also illustrated. As examples of initial applications, the RWT is used for finding road directions in navigation, and for recovering depth in motion stereo. Two types of motion stereo are presented, namely the longitudinal and lateral motion stereo. In all cases, the RWT images offer much reduced and adequate data owing to the variable resolution. Preliminary experimental results from test images of road-vehicle navigation and moving objects on a miniature assembly line are demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The application of linearly swept frequency measurements (1988)

The theory of linearly swept frequency measurements has been studied [M. A. Poletti, J. Audio. Eng. Soc. 36(6) (1988)]. This theory shows that the Fourier transform of a linear system impulse response may be produced as a function of scaled time by convolving, multiplying, and reconvolving the impulse response with infinite duration, complex linear frequency-modulated (FM) signals. The first convolution is implemented by injecting a linear FM signal into the system. The multiplication may be viewed as a synchronous detector that removes the carrier from the output of the system. The third operation may be viewed as a quadratic phase filter that removes the skewing distortion to produce the true transfer function as a function of time. The application of the theory using finite real signals is discussed. It is shown that for a finite duration impulse response a suitably time-limited signal may be injected into the system which produces the response that would be produced with an infinite signal, and that the response to a complex input signal may be produced by sequentially exciting the system with the real and imaginary parts of the complex signal. The second and third complex signals may also be successfully applied to produce the true frequency and phase response of the system without any errors due to the chosen sweep rate.
4C-ker: A Method to Reproducibly Identify Genome-Wide Interactions Captured by 4C-Seq Experiments (2016)

4C-Seq has proven to be a powerful technique to identify genome-wide interactions with a single locus of interest (or "bait") that can be important for gene regulation. However, analysis of 4C-Seq data is complicated by the many biases inherent to the technique. An important consideration when dealing with 4C-Seq data is the differences in resolution of signal across the genome that result from differences in 3D distance separation from the bait. This leads to the highest signal in the region immediately surrounding the bait and increasingly lower signals in far-cis and trans. Another important aspect of 4C-Seq experiments is the resolution, which is greatly influenced by the choice of restriction enzyme and the frequency at which it can cut the genome. Thus, it is important that a 4C-Seq analysis method is flexible enough to analyze data generated using different enzymes and to identify interactions across the entire genome. Current methods for 4C-Seq analysis only identify interactions in regions near the bait or in regions located in far-cis and trans, but no method comprehensively analyzes 4C signals of different length scales. In addition, some methods also fail in experiments where chromatin fragments are generated using frequent cutter restriction enzymes. Here, we describe 4C-ker, a Hidden-Markov Model based pipeline that identifies regions throughout the genome that interact with the 4C bait locus. In addition, we incorporate methods for the identification of differential interactions in multiple 4C-seq datasets collected from different genotypes or experimental conditions. Adaptive window sizes are used to correct for differences in signal coverage in near-bait regions, far-cis and trans chromosomes. Using several datasets, we demonstrate that 4C-ker outperforms all existing 4C-Seq pipelines in its ability to reproducibly identify interaction domains at all genomic ranges with different resolution enzymes.
Direct Digital Processor Control of Stepping Motors (1967)

This paper describes the concept for implementing direct computer control of stepping motors. The design approach is based on using the computer to close a minor loop around the motor. The discussion includes both full and partial computer control, and the results show that the closed-loop stepping motor is well suited to such applications.
Techniques for low energy software (1997)

The energy consumption of a system depends upon the hardware rutd software component of a system. Since it is the software which drives the hardware in most systems. decisions taken during software design has significant impact on the energy consumption of the processor. The paper focuses on decreasing energy consumption of o processor using software techniques. A novel compiler technique is proposed which Educes energy consumption by proper register labeling during the compilation phase. The idea behind this technique is to reduce the energy of the processor by reducing the energy of the instruction register (also the instruction data bus) and the register file decoder by encoding the register labels such that the sum of the switching costs between all the register labels in the tmnsition graph is minimized. There is no hardware pen&y since this is purely a compiler optimization. Results on benchmarks show that the energy consumption of the DLX processor can be. reduced by 9.82% (maximum) and 4.25% (avenge) (as measured by DLX energy simulator). In addition seveml compiler techniques such os loop unrolling, software pipelining, recursion elimination and of effects of different algorithms on power and energy consumption are studied. This evaluation methodology is usefid for computer architects to evaluate energy improvements of their hardware, compiler writers to evaluate energy of the compiled code nnd program writers to evaluate energy of data structures and algodhltls.
The Application Of A Sociotechnical Analysis For The Personally Controlled Electronic Health Record (2012)

Healthcare systems around the globe are facing a number of challenges. Increasing focus is thus being placed on constructing appropriate healthcare reforms which are attempting to address how to tackle these challenges. A critical enabler in these reforms is the adoption of an e-health solution. Such e-health solutions are not only expensive and complex endeavours but also have far reaching implications. Given that the implementation and adoption of these e-health solutions is so important; it is also vital to have an extensive evaluation and analysis of these systems with a theoretically informed lens. This then will serve to maximise and sustain the benefits of the proposed solution and realise its full potential for achieving superior healthcare delivery. To date the literature is void of such evaluations. Hence, this paper proffers the use of a sociotechnical systems (STS) analysis. The exemplar case study under consideration is that of the Personally Controlled Electronic Health Record (PCEHR), the chosen e-health solution by the Australian government.
Note on the Hydrolysis of Amylose by beta‐Amylase (1981)

Abstract Amylose is thought to be a slightly branched polymer with a ß‐amylolysis limit of about 78%. Treating amylose with a mixture of the debranching enzyme pullulanase and ß‐amylase will give 100% conversion to maltose. Interesting one does not obtain 100% conversion if the enzymes are used sequentially. We have found that amylose retrogrades and becomes insoluble while being incubated with pullulanase. Minimum debranching time will give 100% ß‐amylolysis, which we think explains the previously reported need to use the enzymes simultaneously.

Highly accurate data value prediction (2002)

Data dependences (data flow constraints) present a stubborn resistance to the amount of instruction-level parallelism that can be exploited from a program. Recent work has suggested that the limits imposed by data dependences can be overcome to some extent with the use of data value prediction. That is, when an instruction is fetched, its result can be predicted so that subsequent instructions that depend on the result can use this predicted value. When the correct result becomes available, all instructions that are data-dependent on that prediction can be validated. This paper investigates a variety of techniques to carry out highly accurate data value predictions. The first technique investigates the potential of using correlation in data value predictions. The second technique investigates the potential of monitoring the strides by which the results produced by different instances of an instruction change. The third technique investigates the potential of pattern-based two-level prediction schemes. The paper also presents the results from a simulation study that we conducted to verify the potential of the investigated prediction schemes. The results show that highly accurate data valve predictions are possible with two of the investigated schemes.
