A Grid Services-Oriented Architecture for Efficient Operation of Distributed Data Warehouses on Globus (2007)

Data warehouses store large volumes of data according to a multidimensional model that provides a fast access for online analysis. The constant growth in quantity and complexity of data stored in data warehouses has led to a variety of data warehouse applications on distributed systems. The main benefits of these architectures are parallelized query execution and higher storage capacities. Computing grids in particular are built to combine a large number of heterogeneous distributed resources. Their lack of centralized control however conflicts with the centralized structure of classical data warehouses. Autonomous data management on grid nodes requires efficient communication during query evaluation. The architecture we present supports a global data localization method with the help of a specialized catalog service. Our work is based on a model for unique identification and efficient local indexing of the warehouse data. Local indexes integrate computable aggregates for maximum utilization of locally materialized data in order to facilitate cost-optimized query execution. The grid services implementing these functionalities are deployed on the GGM project's test environment.
Titanium Alkoxides as Initiators for the Controlled Polymerization of Lactide (2003)

Fourteen titanium alkoxides were synthesized for comparison of their catalytic properties in the bulk and solution polymerization of lactide (LA). In bulk polymerizations, they are effective catalysts in terms of polymer yield and molecular weight. Titanatranes gave polylactides with significantly increased molecular weight over more extended polymerization times, and those with five-membered rings afforded polymers in higher yields and with larger molecular weights than their six-membered ring counterparts. Steric hindrance of the rings was found to significantly affect polymer yields. Increased heterotactic-biased poly(rac-LA) was formed as the number of chlorine atoms increased in TiCl(x)(O-i-Pr)(4)(-)(x). In solution polymerizations, titanium alkoxides catalyzed controlled polymerizations of LA, and end group analysis demonstrated that an alkoxide substituent on the titanium atom acted as the initiator. That polymerization is controlled under our conditions was shown by the linearity of molecular weight versus conversion. A tendency toward formation of heterotactic-biased poly(rac-LA) was observed in the solution polymerizations. The rate of ring-opening polymerization (ROP) and the molecular weight of the polymers are greatly influenced by the substituents on the catalyst, as well as by factors such as the polymerization temperature, polymerization time, and concentration of monomer and catalyst.
Mechanisms of Thermal and Photodegradations of Bisphenol A Polycarbonate (1996)

This chapter presents an up-to-date review of the literature on the thermal and photodegradations of bisphenol A polycarbonate as well as new results from my laboratory. The areas described include hydrolysis, thermal and thermal oxidative reactions, and photodegradation. Special emphasis is given to the mechanisms of these reactions and to correlating the past work in these areas with more recent results.
An attribute and role based access control model for service-oriented environment (2010)

Based on the analysis of the access control requirements for services, this paper presents an attribute and role based access control model for services. We have described these components in detail and outlined their interactions. The proposed model introduces the notions of business role and service role, defines an automatically produces service role method based on attribute conditions to assign users to service roles, unifies the access control for web services and data resources involved. Finally, we give an access control algorithm for services. This model can provide fine-grained, supporting composite service access control and Mechanism-independent access control policy.

Isolation of a Pax-6 homolog from the ribbonworm Lineus sanguineus. (1996)

The Pax-6 genes of vertebrates and Drosophila encode transcription factors with highly conserved paired- and homeodomains. They are expressed in the nervous system and the developing eyes. Loss-of-function mutations in mammals and flies lead to a reduction or absence of the eyes. By ectopic expression of Pax-6 in Drosophila ectopic eyes can be induced, indicating a determinative role in eye morphogenesis. We have isolated a Pax-6 homolog of the ribbonworm Lineus sanguineus. This gene shares extensive sequence identity and several conserved splice sites with the mammalian and Drosophila genes. During head regeneration the L. sanguineus Pax-6 homolog is expressed in the central nervous system, in the cerebral organ, and in the eye region. These findings support the hypothesis that Pax-6 was present in primitive metazoa before the evolutionary separation of vertebrates and arthropods and suggest a fundamental role in eye and central nervous system development.
Mathematical analysis of Westwood+TCP congestion control (2005)

TCP congestion control is based on an additive-increase/multiplicative-decrease (AIMD) probing paradigm aimed at adapting the sending rate of TCP data sources to match the Internet time-varying available bandwidth. Westwood+ TCP has been recently proposed to improve the tracking of available bandwidth of classic TCP. It is based on an end-to-end estimate of the available bandwidth, which is obtained by properly counting and filtering the stream of acknowledgement packets. The estimate is used to adaptively decrease the congestion window and slow start threshold after congestion so that it can be said that Westwood+ TCP substitutes the classic multiplicative decrease with an adaptive decrease paradigm. The authors propose a mathematical analysis of the additive-increase/adaptive-decrease (AIADD) paradigm to analyse the steady-state throughput provided by Westwood+ TCP and investigate the intra-protocol fairness of the AIADD paradigm and the inter-protocol friendliness between AIADD and AIMD algorithms. It is shown that (i) both classic and Westwood+ TCP provide a throughput that is proportional to 1/√p, where p is the segment drop probability, that is they are friendly to each other; and (ii) the throughput of Westwood+ TCP is proportional to 1/√RTT, where RTT is the round trip time, whereas the throughput of Reno TCP is proportional to 1/RTT, i.e. Westwood+ TCP improves the intra-protocol fairness. Finally, Ns-2 simulations are reported in order to validate the mathematical model in the presence of a wide range of network loads, loss probabilities and round trip times.
Comparative study of fully depleted and body-grounded non fully depleted SOI MOSFETs for high performance analog and mixed signal circuits (1995)

This paper compared the performance of conventional fully depleted (FD) SOI MOSFETs and body-grounded nonfully depleted (NFD) SOI MOSFETs for analog applications, A new low-barrier body-contact (LBBC) technology has been developed to provide effective body contact. Experimental results show that the NFD MOSFET's with LBBC structure give one order of magnitude higher output resistance, significantly lower flicker noise, improved subthreshold characteristics, and minimal threshold voltage variation compared with conventional FD SOI MOSFETs. The device characteristics of the LBBC MOSFET's are more desirable for fabricating high performance analog or mixed analog/digital CMOS circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Performance of State Level Public Enterprises of West Bengal: A Study on the Post Reform Era (2014)

Public sector enterprises (PSEs) once were considered as the Temples of India. But gradually they became such a burden on the Government exchequer that in 1991 we had to take a U-turn on economic policy in general and on PSEs in particular. Since then a number of studies have been conducted to see how the Central Public Enterprises (CPSEs) are working in the changed scenario. But on State Level Public Enterprises (SLPEs), particularly of West Bengal there is hardly any study in post-reform era. In this background, this paper attempts to analyse the performance of SEPEs of West Bengal during the period from 2004-05 to 2010-11. Of three types of SLPEs, e.g, Departmental Undertakings, Public Corporation and Government Companies, the paper has however dealt with last two types of SLPEs as the structural and functional characteristic of first one are largely different from other two.
Citalopram, a Selective Serotonin Reuptake Inhibitor, Improves Symptoms of Friedreich's Ataxia (1999)

Two patients (siblings) with Friedreich's ataxia showed improvement in their clinical symptoms--particularly spasticity and cardiac symptoms--after treatment with the selective serotonin reuptake inhibitor citalopram.
Peripheral Signals Conveying Metabolic Information to the Brain: Short-Term and Long-Term Regulation of Food Intake and Energy Homeostasis (2001)

Numerous peripheral signals contribute to the regulation of food intake and energy homeostasis. Mechano- and chemoreceptors signaling the presence and energy density of food in the gastrointestinal (GI) tract contribute to satiety in the immediate postprandial period. Changes in circulating glucose concentrations appear to elicit meal initiation and termination by regulating activity of specific hypothalamic neurons that respond to glucose. Other nutrients (e.g., amino acids and fatty acids) and GI peptide hormones, most notably cholecystokinin, are also involved in short-term regulation of food intake. However, the energy density of food and short-term hormonal signals by themselves are insufficient to produce sustained changes in energy balance and body adiposity. Rather, these signals interact with long-term regulators (i.e., insulin, leptin, and possibly the orexigenic gastric peptide, ghrelin) to maintain energy homeostasis. Insulin and leptin are transported into the brain where they modulate expression of hypothalamic neuropeptides known to regulate feeding behavior and body weight. Circulating insulin and leptin concentrations are proportional to body fat content; however, their secretion and circulating levels are also influenced by recent energy intake and dietary macronutrient content. Insulin and leptin concentrations decrease during fasting and energy-restricted diets, independent of body fat changes, ensuring that feeding is triggered before body energy stores become depleted. Dietary fat and fructose do not stimulate insulin secretion and leptin production. Therefore, attenuated production of insulin and leptin could lead to increased energy intake and contribute to weight gain and obesity during long-term consumption of diets high in fat and/or fructose. Transcription of the leptin gene and leptin secretion are regulated by insulin-mediated increases of glucose utilization and appear to require aerobic metabolism of glucose beyond pyruvate. Other adipocyte-derived hormones and proteins that regulate adipocyte metabolism, including acylation stimulating protein, adiponectin, diacylglycerol acyltransferase, and perilipin, are likely to have significant roles in energy homeostasis.

Structural and Functional Comparisons of Nucleotide Pyrophosphatase/Phosphodiesterase and Alkaline Phosphatase:  Implications for Mechanism and Evolution<sup>,</sup> (2006)

The rapid expansion of the amount of genomic and structural data has provided many examples of enzymes with evolutionarily related active sites that catalyze different reactions. Functional comparisons of these active sites can provide insight into the origins of the enormous catalytic proficiency of enzymes and the evolutionary changes that can lead to different enzyme activities. The alkaline phosphatase (AP) superfamily is an ideal system to use in making such comparisons given the extensive data available on both nonenzymatic and enzymatic phosphoryl transfer reactions. Some superfamily members, such as AP itself, preferentially hydrolyze phosphate monoesters, whereas others, such as nucleotide pyrophosphatase/phosphodiesterase (NPP), preferentially hydrolyze phosphate diesters. We have measured rate constants for NPP-catalyzed hydrolysis of phosphate diesters and monoesters. NPP preferentially catalyzes diester hydrolysis by factors of 10(2)-10(6), depending on the identity of the diester substrate. To identify features of the NPP active site that could lead to preferential phosphate diester hydrolysis, we have determined the structure of NPP in the absence of ligands and in complexes with vanadate and AMP. Comparisons to existing structures of AP reveal bimetallo cores that are structurally indistinguishable, but there are several distinct structural features outside of the conserved bimetallo site. The structural and functional data together suggest that some of these distinct functional groups provide specific substrate binding interactions, whereas others tune the properties of the bimetallo active site itself to discriminate between phosphate diester and monoester substrates.
Wave mixing in semiconductor laser amplifiers due to carrier heating and spectral-hole burning (1994)

Theoretical results on wave mixing in traveling-wave semiconductor laser amplifiers are presented. Starting from rather general density-matrix equations, including the effects of carrier-density pulsations, carrier heating, and spectral-hole burning, we derive equations capable of treating the range from nearly degenerate to highly nondegenerate four-wave mixing. The equations are solved numerically, and comparison to published experimental results is made. The theoretical results explain different experimental results, which have been taken to support either the role of spectral-hole burning or that of carrier heating in mediating wave mixing under highly nondegenerate conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Learning Continuous Attractors in Recurrent Networks (1997)

One approach toinvariant object recognition employs a recurrent neural network as an associative memory. In the standard depiction of the network&apos;s state space, memories of objects are stored as attractive xed points of the dynamics. I argue for a modi cation of this picture: if an object has a continuous family of instantiations, it should be represented by a continuous attractor. This idea is illustrated with a network that learns to complete patterns. To perform the task of lling in missing information, the network develops a continuous attractor that models the manifold from which the patterns are drawn. From a statistical viewpoint, the pattern completion task allows a formulation of unsupervised learning in terms of regression rather than density estimation. A classic approach toinvariant object recognition is to use a recurrent neural network as an associative memory[1]. In spite of the intuitive appeal and biological plausibility of this approach, it has largely been abandoned in practical applications.
Optimization of DSF- and SOA-based phase conjugators by incorporating noise-suppressing fiber gratings (1997)

We compare the performance of dispersion-shifted-fiber (DSF) and semiconductor-optical-amplifier (SOA) based laser phase conjugators for a 10-Gb/s nonreturn-to-zero system with respect to conversion efficiency, noise figure, and distortion. Fiber gratings are used for signal extraction and amplified spontaneous emission (ASE) suppression, allowing closer wavelength spacing and reducing the conjugation noise figure by up to 12 dB. Despite the higher SOA conversion efficiency, both conjugators give similar noise figures with ASE suppression. However, the DSF-based conjugator has the advantage of distortion tolerance at higher input power.

Deakin Law Oration: Unelected Does Not Equate with Undemocratic: Parliamentary Sovereignty and the Role of the Judiciary (2008)

One feature of judicial life that strikes most appointees to judicial office early on is the silence of the Judiciary outside our judgments and statements in court. We are also struck, when we deliver our first judgment that raises controversy or higher public interest, by the vulnerability of the Judiciary to criticism, sometimes vehement and trenchant. Judges do not answer back. With the exception of Chief Justices, judges are generally only heard in court, unless the speaking occasion involves an extra-curial or academic discussion on the law or judicial life. This is properly so. Yet, when the criticism comes, it is troubling. Judges understand the constitutional and governmental conventions that operate and within which they work. The conventions are not complicated, in fact quite simple. The only regret is that they are forgotten or overlooked when the criticism is made. For this evening's purpose I would wish to reflect on the conventions that judges work within. I will set out the traditional and modern views on parliamentary sovereignty. I will address the doctrine of separation of powers and the role of judicial power. I will postulate that, in modern government, it is the rule of law that is sovereign. I will consider the judicial role and the development of the common law. I will address the topics of judicial activism, the election of judges and judicial accountability. I will conclude with the view that the complaint of judicial activism is misplaced and involves a misapprehension of the judicial function. For some, the high water mark of judicial activism was Mabo. For some, the nadir of judicial 'inactivism' was Al Kateb. These swings of the pendulum in the discussion of judges' work are not new. In 1956, Boilermakers' was an unsatisfactory outcome for some. Similarly, in 1948, the Bank Nationalisation decision provoked criticism. When Chief Justice Dixon restrained the Victorian Government from carrying out the execution in Tait, criticism ensued. However, each time judicial power prevailed over parliamentary and executive power. Was that undemocratic? My discussion does not say anything new. It has been said before. But, it needs to be said again. I turn then to the topic for consideration.
Hyperentangled Time-Bin and Polarization Quantum Key Distribution (2022)

Fiber-based quantum communication networks are currently limited without quantum repeaters. Satellite-based quantum links have been proposed to extend the network domain. We develop a quantum communication system, suitable for realistic satellite-to-ground communication. With this system, we execute an entanglement-based quantum key distribution (QKD) protocol developed by Bennett, Brassard, and Mermin (BBM92), achieving quantum bit-error rates (QBERs) below 2% in all bases. More importantly, we demonstrate low-QBER execution of a higher-dimensional hyperentanglement-based QKD protocol, using photons simultaneously entangled in polarization and time bin, leading to significantly higher secure key rates, at the cost of increased technical complexity and system size. We show that our protocol is suitable for a space-to-ground link, after incorporating Doppler-shift compensation, and verify its security using a rigorous finite-key analysis. Additionally, we discuss system-engineering considerations relevant to those and other quantum communication protocols and their dependence on what photonic degrees of freedom are utilized.
Acrylate Formation from CO<sub>2</sub>and Ethylene Mediated by Nickel Complexes: A Theoretical Study (2014)

The first step of the nickel-mediated synthesis of acrylates from carbon dioxide (CO2) and ethylene is the formation of nickelalactones. Nickelalactones could then react to give complexes containing acrylic acid moieties. Such a spontaneous reaction, however, is usually not observed and most progress has recently been made by cleaving the lactones with auxiliaries such as Lewis acids and strong bases. Here we investigate in detail the coupling of CO2 and ethylene and further reactivity in absence of auxiliaries mediated by nickel complexes bearing bidentate ligands. We have found a new mechanism for lactone formation which, for some bidentate ligands, is favored over the mechanism described in the literature. Furthermore, we found that β-H elimination leading to ring contraction of the lactone is almost feasible at room temperature. Importantly, however, all investigated mechanisms for formation of acrylic acid complexes require higher activation free energies of ca. 130 kJ/mol and are not accessible at ambient or slightly elevated temperatures.
Inhibition of early tumor growth requires J alpha 18-positive (natural killer T) cells. (2003)

The role of natural killer T (NKT) cells in the immune response to tumor cells has been largely unexplored. As a model of adoptive tumor immunotherapy, cells from the draining lymph nodes of mice immunized with a tumor-specific or irrelevant antigen were transferred to naïve recipients with established tumor. Inhibition of early tumor growth (day 4) required the transfer of both CD8(+) and J alpha 18(+) (NKT) cells from immunized animals without regard to immunogen. In contrast, CD8(+) cells, but not J alpha 18(+) cells, were necessary for the inhibition of late tumor growth (day 8). Thus, the developing tumor changes in sensitivity to NKT-mediated events and the role for NKT cells cannot be replaced by the presence of tumor-specific cells during early tumor growth. This suggests that recruitment/activation of J alpha 18(+) NKT cells is an important consideration during the immune therapy of early stage tumors.
