Efficient and Reliable Broadcast in Intervehicle Communication Networks: A Cross-Layer Approach (2010)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Broadcast transmission is an effective way to disseminate safety-related information for cooperative driving in intervehicle communication (IVC). However, it is fraught with fundamental challenges such as message redundancy, link unreliability, hidden terminals, and broadcast storms, which greatly degrade network performance. In this paper, we introduce a cross-layer approach to design an efficient and reliable broadcast protocol for emergency message dissemination in IVC systems. We first propose a novel composite relaying metric for relay selection by jointly considering geographical locations, physical-layer channel conditions, and moving velocities of vehicles. Based on the relaying metric, a distributed relay-selection scheme is proposed to assure that a unique relay is selected to reliably forward the emergency message in the desired propagation direction. We further apply IEEE 802.11e enhanced distributed coordination access (EDCA) medium-access control (MAC) to guarantee quality-of-service (QoS) provisioning to safety-related services. In addition, an analytical model is developed to study the performance of the proposed cross-layer broadcast protocol (CLBP) in terms of the relay-selection delay and the emergency message access delay. Network Simulator (NS-2) simulation results are given to validate our analysis. It is shown that the CLBP not only can minimize the broadcast message redundancy but can quickly and reliably deliver emergency messages in IVC as well. </para>

Economics of Domestic Solar Hot Water Heating Systems in Malaysia (2009)

Malaysia has favorable climatic conditions for the development of solar energy due to the abundant sunshine and is considered good for harnessing energy from the sun. This is because solar hot water can represent the large energy consumer in Malaysian households but, because of the high initial cost of Solar Water Heating Systems (SWHSs) and easily to install and relatively inexpensive to purchase electric water heaters, many Malaysian families are still using Electric Water Heaters to hot their water needs. This paper is presented the comparing of techno-economic feasibility of some models of SWHS from Malaysian's market with the Electric Water Heaters (EWH) by study the annual cost of operation for both systems. The result shows that the annual cost of the electrical water heater becomes greater than the annual cost of the SWHS for all models in long-term run so it is advantageous for the family to use the solar water heater, at least after 4 years. In addition with installation SWHS the families can get long-term economical benefits,
Experimental comparison of discrete and CMOS charge sensitive preamplifiers for CZT radiation detectors (2003)

During recent years, many readout integrated circuits for CdZnTe (CZT) radiation detectors have been studied particularly for use on pixellated detectors in imaging applications. The fundamental challenge is to keep noise performance similar to discrete preamplifiers, even with lower power. This paper presents an experimental evaluation of CMOS integrated charge sensitive preamplifiers intended for CZT radiation detectors using a comparison with discrete preamplifiers.
Region of interest priority coding for sign language videoconferencing (2002)

This paper investigates compression of sign-language video sequences for transmission over low bitrate channels. The motion of hands and arms inherent in sign language requires high temporal resolution and greater compression for band-limited channels. Most existing compression schemes treat the entire image uniformly. However, the background is much less critical than the foreground for sign language communication. A new algorithm is developed that gives priority to the foreground and sacrifices the quality of the background to achieve higher compression rates and higher foreground quality without compromising the frame rate. The algorithm is extended to use a dynamic region of interest defined by face and hand location. Results show that the frame rate and quality of the region of interest are higher than with uniform algorithms.
The transcriptional repressor REST is a critical regulator of the neurosecretory phenotype (2006)

Release of distinct cellular cargoes in response to specific stimuli is a process fundamental to all higher eukaryotes and controlled by the regulated secretory pathway (RSP). However, the mechanism by which genes involved in the RSP are selectively expressed, leading to the establishment and appropriate functioning of regulated secretion remaining largely unknown. Using the rat pheochromocytoma cell line PC12, we provide evidence that, by controlling expression of many genes involved in the RSP, the transcriptional repressor REST can regulate this pathway and hence the neurosecretory phenotype. Introduction of REST transgenes into PC12 cells leads to the repression of many genes, the products of which are involved in regulated secretion. Moreover, chromatin immunoprecipitation assays show that many of the repressed genes recruit the recombinant REST protein to RE1 sites within their promoters and abrogation of REST function leads to reactivation of these transcripts. In addition to the observed transcriptional effects, PC12 cells expressing REST have fewer secretory granules and a reduction in the ability to store and release noradrenaline. Furthermore, an important trigger for synaptic release, influx of calcium through voltage-operated calcium channels, is compromised. This is the first demonstration of a transcription factor that directly controls expression of many major components of the RSP and provides further insight into the function of REST.
Desensitization of neuronal nicotinic receptors (2002)

The loss of functional response upon continuous or repeated exposure to agonist, desensitization, is an intriguing phenomenon if not as yet a well-defined physiological mechanism. However, detailed evaluation of the properties of desensitization, especially for the superfamily of ligand-gated ion channels, reveals how the nervous system could make important use of this process that goes far beyond simply curtailing excessive receptor stimulation and the prevention of excitotoxicity. Here we will review the mechanistic basis of desensitization and discuss how the subunit-dependent properties and regulation of nicotinic acetylcholine receptor (nAChR) desensitization contribute to the functional diversity of these channels. These studies provide the essential framework for understanding how the physiological regulation of desensitization could be a major determinant of synaptic efficacy by controlling, in both the short and long term, the number of functional receptors. This type of mechanism can be extended to explain how the continuous occupation of desensitized receptors during chronic nicotine exposure contributes to drug addiction, and highlights the potential significance of prolonged nAChR desensitization that would also occur as a result of extended acetylcholine lifetime during treatment of Alzheimer's disease with cholinesterase inhibitors. Thus, a clearer picture of the importance of nAChR desensitization in both normal information processing and in various diseased states is beginning to emerge.
On a Bit-Serial Input and Bit-Serial Output Multiplier (1983)

A recent paper by Chen and Willoner [1] forwarded a bit-sequential input and output (LSBfirst) multiplier for positive numbers. This multiplier for n-bit operands requires 2n clocks and 2n number of five-input adder modules. In this correspondence, after a brief discussion on the different claims made by the authors of [1] and their limitations, we show that this multiplier can be realized with only n adder modules. The technique is extended to two's complement number system. Also, a more complete picture of the actual implementation is depicted. Finally, we bring to the attention an already existing multiplier which fits into the bit-sequential multiplier category.

Trivalent ion exchange in beta' alumina. Technical report (1984)

In many clinical studies published over the past 20 years, adolescents and young adults (AYA) with Philadelphia chromosome negative acute lymphoblastic leukemia (Ph- ALL) were considered as a rather homogeneous clinico-prognostic group of patients suitable to receive intensive pediatric-like regimens with an improved outcome compared with the use of traditional adult ALL protocols. The AYA group was defined in most studies by an age range of 18-40 years, with some exceptions (up to 45 years). The experience collected in pediatric ALL with the study of post-induction minimal residual disease (MRD) was rapidly duplicated in AYA ALL, making MRD a widely accepted key factor for risk stratification and risk-oriented therapy with or without allogeneic stem cell transplantation and experimental new drugs for patients with MRD detectable after highly intensive chemotherapy. This combined strategy has resulted in long-term survival rates of AYA patients of 60-80%. The present review examines the evidence for MRD-guided therapies in AYA's Ph- ALL, provides a critical appraisal of current treatment pitfalls and illustrates the ways of achieving further therapeutic improvement according to the massive knowledge recently generated in the field of ALL biology and MRD/risk/subset-specific therapy.
Optical Information Processing (2010)

This chapter describes applications of active optical-switching devices to serial-to-parallel data conversion, an optical self-routing switch, an optical ATM switch, an optical interconnection, an optical memory, and an optical bus. For future parallel information processing it is necessary to prepare a device that can perform serial-to-parallel data conversion. In addition, a reconfigurable optical interconnection is needed. The chapter illustrates a single VSTEP circuit and a differential VSTEP circuit for optical interconnections. A VSTEP has multiple functions, such as light emission, light absorption, thresholding, and latching. These features allow us to construct an optical pulse repeater easily. The chapter describes an optical fiber loop memory that uses a VSTEP as a simple optical pulse repeater. The VSTEP can reshape a degraded optical pulse and make it possible to achieve a long storage time without any circuitry.

Trichostatin C, a glucopyranosyl hydroxamate. (1978)

In addition to trichostatins A and B, a new antifungal antibiotic, trichostatin C was isolated. The structure was shown to be a glucoside of trichostatin A by spectroscopic examinations and chemical degradations. Trichostatin C is presumably the first example of a glucopyranosyl hydroxamate from nature.
Advanced predictive-analysis-based decision support for collaborative logistics networks (2015)

Purpose – The purpose of this paper is to examine challenges and potential of big data in heterogeneous business networks and relate these to an implemented logistics solution. Design/methodology/approach – The paper establishes an overview of challenges and opportunities of current significance in the area of big data, specifically in the context of transparency and processes in heterogeneous enterprise networks. Within this context, the paper presents how existing components and purpose-driven research were combined for a solution implemented in a nationwide network for less-than-truckload consignments. Findings – Aside from providing an extended overview of today’s big data situation, the findings have shown that technical means and methods available today can comprise a feasible process transparency solution in a large heterogeneous network where legacy practices, reporting lags and incomplete data exist, yet processes are sensitive to inadequate policy changes. Practical implications – The means introduced in the paper were found to be of utility value in improving process efficiency, transparency and planning in logistics networks. The particular system design choices in the presented solution allow an incremental introduction or evolution of resource handling practices, incorporating existing fragmentary, unstructured or tacit knowledge of experienced personnel into the theoretically founded overall concept. Originality/value – The paper extends previous high-level view on the potential of big data, and presents new applied research and development results in a logistics application.
The principle of assessing mental capacity for enduring power of attorney (2014)

With Hong Kong's rapidly ageing population, increasing numbers of people now have some form of cognitive impairment. Enduring power of attorney is a legal instrument that can allow individuals to manage their financial matters if they subsequently become mentally incapacitated. The law requires that the mental capacity of the individual making an enduring power of attorney should be certified by a registered medical practitioner and a solicitor. This paper discusses the principles involved in the assessment of mental capacity for making an enduring power of attorney and uses this example to illustrate various important considerations in the formal assessment of mental capacity.
Glycosyl Transfer from Dolichyl Phosphate Sugars to Endogenous and Exogenous Glycoprotein Acceptors in Yeast (1978)

Participation of sugars activated by dolichyl diphosphate (Dol-PP) in the formation of N-glycosidic linkages was studied with the following results. 1. A preparative method is described for quantitative separation of Dol-PP-GlcNAc from Dol-PP-(GlcNAc)2 and from Dol-PP-(GlcNAc)2-Man (where GlcNAc is N-acetylglucosamine and Man is mannose). 2. Yeast membranes catalyze the transfer of both di-N-acetylchitobiose and mannosyl-di-N-acetylchitobiose from the dolichyl-diphosphate-bound form to endogenous glycoproteins, however hardly at all the transfer of N-actylglucosamine alone. The trisaccharide is transferred more efficiently than the disaccharide. 3. Hydrazinolysis of the newly synthesized glycoprotein shows that indeed the disaccharide and trisaccharide are transferred as such; under the experimental conditions, therefore, no extension to a larger lipid-bound oligosaccharide has to take place before transfer to the glycoprotein is possible. 4. When the Dol-PP-[14C]disaccharide or trisaccharide is incubated together with non-radioactive GDP-Man, and yeast membranes, subsequent hydrazinolysis of the newly formed glycoprotein yields in either case only the [14C]trisaccharide; further mannosylation of the trisaccharide unit via GDP-Man does not occur at the protein level in vitro. Participation of dolichyl-phosphate-activated mannose in the formation of O-glycosidic linkages was studied with the following results. 1. Mannose is linked to yeast dolichyl phosphate as the β-anomer. 2. Exogenously added yeast cell wall mannoprotein (fraction A) serves as acceptor for mannosyl groups when GDP-Man or Dol-P-Man is acting as mannosyl donor. This is considered to be the first evidence for the involvement of dolichyl-phosphate-activated sugars in serine/threonine glycosylation of extracellular glycoproteins.

Protective Effect of New Nitrosothiols on the Early Inflammatory Response to Kidney Ischemia/Reperfusion and Transplantation in Rats (2009)

Renal ischemia/reperfusion (I/R) is characterized by severe inflammatory damage. We assessed the effect of administrating recently developed nitrosothiol compounds acting as nitric oxide (NO) donors on the production of cytokines and other markers of acute inflammatory reaction in an experimental model of warm (I/R), and in a model of cold ischemia and transplant in rats. Warm ischemia was achieved by ligation of left renal pedicle for 60 min, followed by contralateral nephrectomy. NO-donors LA-803, LA-807, LA-810 were administered i.v. (1.8 micromol/kg) during 30 min before reperfusion. Cold ischemia was achieved by preservating the kidney for 24 h in Euro Collins and grafting it in consanguineous Fisher 344/Ico rats. LA-803 was administered in the preservation fluid and in the recipient rat. Reperfusion time was 4 h in warm ischemia and 3 h in cold ischemia + transplantation. Administration of LA-803, LA-807 and, in a lower proportion, LA-810 prevented from the enhanced production of tumor necrosis factor (TNF), interferon-gamma (IFN-gamma), and interleukin-1beta (IL-1beta), the decrease in interleukin-6 (IL-6) and interleukin-10 (IL-10), the increase in tissue level of superoxide anion (SOA) and superoxide dismutase (SOD), and the increase in neutrophil infiltration induced by warm I/R. Treatment with LA-803 in animals with renal transplantation after cold ischemia was also associated with reduced plasma levels of TNF, IFN-gamma, and IL-1beta, increased plasma levels of IL-6 and IL-10, reduced renal levels of SOA and SOD, and reduced neutrophil infiltration. These data demonstrate that systemic administration of new NO-donors with nitrosothiol structure diminished inflammatory responses in a kidney subjected to warm I/R or cold ischemia and transplantation.
Pisum sativum AND Vicia faba CARBOHYDRATES: STUDIES OF FRACTIONS OBTAINED AFTER DRY AND WET PROTEIN EXTRACTION PROCESSES (1980)

ABSTRACT The distribution and the composition of the oligosaccharides, starch, and cell‐wall polysaccharides were determined on the lower protein air‐classified flours of broadbeans, smooth peas, and wrinkled peas and the starchy by‐products obtained after the wet process. α‐Galactosides are still present in the air‐classified fractions whereas they are almost extracted by wet process. In contrast, the fiber content was high in the starchy by‐product and in both cases, the sugar constituents of hemicelluloses material indicate that the fraction still present is not representative of the initial hemicelluloses. Starches were isolated in a high yield (60%) from air‐classified flours whereas the isolation was not possible from the starchy by‐product, probably due to the high hemicelluloses content preventing their extraction. The laboratory scale purification has led to refined starches with no effect of the process on the granules as viewed by light and electron microscopies.
