Performance evaluation of scheduling algorithms for database services with soft and hard SLAs (2011)

Database service providers face heterogeneous customer workloads with widely varying characteristics. The query scheduling plays a critical role in serving such workloads and involves the careful consideration of specific requirements introduced in service provisioning environments. As a part of our real platform building process, we have collected specific requirements for the scheduling framework through extensive interactions with business organizations that provide services to real clients. Although there is a very large body of previous work in the scheduling area, there is no single scheduling method that is designed to satisfy all of our requirements. However, some of them may address certain aspects of those requirements. In this work, we rigorously evaluate a comprehensive set of such scheduling methods and present how they perform with respect to the full requirements list. We also propose and evaluate an effective extension to the most promising method, iCBS, we identified through the evaluations in this space.
Enabling Use of Single Password over Multiple Servers in Two-Server Model (2010)

The two-server model is quite promising for password based authentication, well suited for the setting of federated enterprises. However, none of the existing two-server password based authentication schemes enables a user to use the same password over multiple service servers, which is deemed an important feature of the two-server model. In this paper, we propose a new scheme, enabling this prominent functionality. Our proposed scheme is password-only, and slightly more efficient than the latest two-server password based authentication scheme.
A Framework for Analyzing Customer Service Orientations in Manufacturing (1989)

The proposed framework first clarifies the concept of customer service in a manufacturing context. Then the key strategic choices associated with emphasizing a customer service–oriented strategy are specified. Next, the organizational arrangements necessary to implement these strategic choices are described. Finally, alternative effective configurations of the strategic choices, organizational arrangements, and customer service activities are proposed. Research propositions are presented that focus on the relationship between central contingencies in the strategic management literature and customer service in manufacturing.
How Much Time Should the Police Spend at Crime Hot Spots? Answers from a Police Agency Directed Randomized Field Trial in Sacramento, California (2012)

Hot spots policing has been shown to be an effective strategy for reducing crime across a number of rigorous evaluations, but despite this strong body of research, there still exist gaps in our knowledge of how officers can best respond to hot spots. We report on a randomized experiment in Sacramento, California that begins to address these gaps by testing the recommendation from prior research that police officers randomly rotate between hot spots, spending about 15 min patrolling in each. Our results suggest significant overall declines in both calls for service and crime incidents in the treatment hot spots relative to the controls. Additionally, the study was carried out primarily by the Sacramento Police Department without any outside funding. In an era of limited economic resources for policing, this experiment suggests a model by which police agencies can take ownership of science and oversee the implementation and evaluation of evidence-based interventions.
Lithium niobate ridge waveguide modulator (1974)

A narrow ridge was ion‐beam etched on an outdiffused LiNbO3 crystal to form a single‐mode waveguide confining the beam in both transverse dimensions. Electrodes were evaporated along the ridge to produce a very efficient electro‐optic phase modulator requiring a power of 20 μ W/MHz of bandwidth and a voltage of 1.2 V to produce a modulation index of 1 rad.

Heterozygous Germ Line <i>hCHK2</i> Mutations in Li-Fraumeni Syndrome (1999)

The hCHK2 gene encodes the human homolog of the yeast Cds1 and Rad53 G2 checkpoint kinases, whose activation in response to DNA damage prevents cellular entry into mitosis. Here, it is shown that heterozygous germ line mutations in hCHK2 occur in Li-Fraumeni syndrome, a highly penetrant familial cancer phenotype usually associated with inherited mutations in the TP53 gene. These observations suggest that hCHK2 is a tumor suppressor gene conferring predisposition to sarcoma, breast cancer, and brain tumors, and they also provide a link between the central role of p53 inactivation in human cancer and the well-defined G2 checkpoint in yeast.
Characterization of an Elastically Stretchable Microelectrode Array and Its Application to Neural Field Potential Recordings (2009)

Elastically stretchable microelectrode arrays (SMEAs) were fabricated, and their functionality was tested by recording field potentials from neural tissue. The SMEA includes 11 microelectrodes, each with a recording area of and a reference electrode. The microelectrodes were fabricated by depositing and patterning thin-film gold conductors on the elastomeric substrate poly(dimethylsiloxane). A photopatternable silicone was used to encapsulate the microelectrodes and pattern vias for electrical contact. The recording sites of the microelectrodes were electroplated with platinum black to reduce the impedance of the electrode/electrolyte interface. Spontaneous and stimulus-evoked activity was recorded from hippocampal slices placed on an array that was biaxially stretched up to 13.3%. No appreciable difference in microelectrode properties was detected before and after stretching, demonstrating that the microelectrodes can be stretched reversibly.
Three‐dimensional electron microscopy reconstruction and cysteine‐mediated crosslinking provide a model of the type <scp>III</scp> secretion system needle tip complex (2014)

Type III secretion systems are found in many Gram-negative bacteria. They are activated by contact with eukaryotic cells and inject virulence proteins inside them. Host cell detection requires a protein complex located at the tip of the device's external injection needle. The Shigella tip complex (TC) is composed of IpaD, a hydrophilic protein, and IpaB, a hydrophobic protein, which later forms part of the injection pore in the host membrane. Here we used labelling and crosslinking methods to show that TCs from a ΔipaB strain contain five IpaD subunits while the TCs from wild-type can also contain one IpaB and four IpaD subunits. Electron microscopy followed by single particle and helical image analysis was used to reconstruct three-dimensional images of TCs at ∼ 20 Å resolution. Docking of an IpaD crystal structure, constrained by the crosslinks observed, reveals that TC organisation is different from that of all previously proposed models. Our findings suggest new mechanisms for TC assembly and function. The TC is the only site within these secretion systems targeted by disease-protecting antibodies. By suggesting how these act, our work will allow improvement of prophylactic and therapeutic strategies.
Arsenic Removal from Drinking Water during Coagulation (1997)

The efficiency of arsenic removal from source waters and artificial freshwaters during coagulation with ferric chloride and alum was examined in bench-scale studies. Arsenic(V) removal by either ferric chloride or alum was relatively insensitive to variations in source water composition below pH 8. At pH 8 and 9, the efficiency of arsenic(V) removal by ferric chloride was decreased in the presence of natural organic matter. The pH range for arsenic(V) removal with alum was more restricted than with ferric chloride. For source waters spiked with 20 μg/L arsenic(V), final dissolved arsenic(V) concentrations in the product water of less than 2 μg/L were achieved with both coagulants at neutral pH. Removal of arsenic(III) from source waters by ferric chloride was both less efficient and more strongly influenced by source water composition than removal of arsenic(V). The presence of sulfate (at pH 4 and 5) and natural organic matter (at pH 4 through 9) adversely affected the efficiency of arsenic(III) removal by ferric chloride. Arsenic(III) could not be removed from source waters by coagulation with alum.
Development and testing of an infrared target tracking system (2010)

A novel design for an active point ranging and tracking instrument intended for large work volume applications, is presented in this thesis. The proposed instrument employs two tracking stations at a known baseline distance in order to triangulate on, and dynamically track a pulsed infrared target A prototype instrument, consisting of a single target tracking station and modulated target, has been built and tested. Each target tracking station is composed of a gimbaled mirror optic deflection system and an infrared sensitive camera. The angular resolving capability of the target tracking station is approximately 0.1 degrees when locked on a static target. The target tracking station is able to follow a target moving at a maximum speed of 4.9 meters per second at a distance of 1 meter. Results of static and dynamic testing performed on separate components of the prototype instrument, and on the complete target tracking station are presented.
[The loss of CpG dinucleotides from DNA. III. Methylation and evolution of histone genes]. (1987)

From nucleotide sequences of more than 70 histones genes in 15 species of eucaryotes the probable frequency was determined for CpG----TpG + CpA substitutions, occurring as a result of deamination of 5-methylcytosine residues in DNA. It was found that histone genes differ in the character of CpG methylation with respect to the species studied and may be divided into three groups differing in the value of CpG suppression. In one of them, M-, CpG dinucleotides must have not been methylated throughout the existence of these genes; in another, M+, nearly every other CpG has undergone transition. In the third group, M +/-, no more than 20% of CpG have steadily undergone methylation (and mutation). The CpG deficiency in M+ and M +/- histone genes is in general proportional to the level of methylation of total DNA in different species. It has been noted that the genes of different core histones in the same organism are characterized, as a rule, by the same type of CpG methylation and belong to the same group. Genes H1 and H5 show a higher level of CpG suppression and thus have a higher degree of methylation than the genes of core histones from the same organism. The most conserved among the histone genes, those for H3 and H4 in particular, must have not been methylated in the majority of the species studied. The distribution of methylated and non-methylated spacers and coding sequences of histone genes of man, mouse, hen and yeast reveals a mosaic pattern. It has been found that 5'-flanked regions in most cases are methylated more than respective genes, while the G + C content in them is significantly lower, compared with the coding gene sequences. The absence of methylation in the 5'-regulatory regions does not appear to be mandatory for histone genes. It has been established that the genes of the same histones may differ in the level of methylation even in more or less closely related species. Group M- comprises genes of core histones of man, hen, sea urchin, Drosophila, Neurospora and wheat; group M +/- includes analogous genes of mouse, Xenopus, trout and sea urchins. The results obtained testify against the possible universal involvement of methylation in the regulation of histone gene expression.
High density magnetic recording system with perpendicular magnetic anisotropy film. (1987)

By using a perpendicular magnetization mode to the surface of a recording medium, a new recording system that has extremely high volume density will be realized. Its minimum bit-length corresponds to the crystalline particle size which is about one-tenth the thickness of a perpendicular magnetic anisotropy film used for recording media. For writing and reading, a single pole type magnetic head made of a soft magnetic thin film has been also proposed. In this paper, the principles, methods and feasibilities of perpendicular magnetic recording are described.
Principle and Technical Characteristics of Non-Contact Magnetic Tomography Method Inspection for Oil and Gas Pipeline (2011)

Non-contact magnetic tomography method (MTM) is an effective non-de inspection technology used widely in recent years, which is good at the type definition and hazard assessment of corrosion defects, mechanical damage, crack-like defects, stress corrosion cracking and stress deformation for metal oil and gas pipeline. Based on the metal magnetostrictive effect and inspection method of the pipeline magnetic field stress, the principle and technical characteristics of MTM are discussed in the paper. Combining detecting process and results of this method, technical characteristics and the application ranges are analyzed together, this will provide direct reference and basis for oil &gas pipeline Integrity inspection and safety assessment.
Augmented reality in Education &#x2014; Cases, places, and potentials (2013)

Augmented Reality is poised to profoundly transform Education as we know it. The capacity to overlay rich media onto the real-world for viewing through web-enabled devices such as phones and tablet devices means that information can be made available to students at the exact time and place of need. This has the potential to reduce cognitive overload by providing students with `perfectly situated scaffolding', as well as enable learning in a range of other ways. This paper will review uses of Augmented Reality both in mainstream society and in education, and discuss the pedagogical potentials afforded by the technology. Based on the prevalence of information delivery uses of Augmented Reality in Education, we argue the merit of having students design Augmented Reality experiences in order to develop their higher order thinking capabilities. A case study of `learning by design' using Augmented Reality in high school Visual Art is presented, with samples of student work and their feedback indicating that the approach resulted in high levels of independent thinking, creativity and critical analysis. The paper concludes by establishing a future outlook for Augmented Reality and setting a research agenda going forward.
A Really Interesting Story: The Influence of Narrative in Linguistic Change (2012)

The intensifier system is well known for its perpetual recycling of fresh innovations; however, neither qualitative nor quantitative analyses have offered a consensus on which social factors are involved in the increased use of one variant at the expense of another, nor do we know much about sites of innovation. In this paper, we delve deep into the intensifier system by considering the distinction between narrative and non-narrative discourse contexts (Labov and Waletsky 1967) and using a “small-within-large” methodology wherein a subset of data from a broad sociolinguistic study is our foundation (Tagliamonte 2008). Our results reveal that narratives have significantly higher intensification rates than non-narratives, which we interpret as a linguistic resource to increase affective meaning when performing the identity work inherent in storytelling (Schiffrin 1996). Further, the statistically significant predictors for intensifier use in narratives are predominantly semantic, involving adjective type and emotional value with no significant social factors. Yet in non-narrative discourse, syntactic factors predominate and both gender and age are statistically significant effects. Partitioning the data by discourse context uncovers additional sociolinguistic bifurcation. Indeed, a more detailed examination of the interaction of speaker age and gender reveals how critical the narrative/non-narrative contrast is in the ebb and flow of changes within this system. While younger speakers of both genders show an increase in really in narratives, in non-narratives younger women exhibit a heightened usage compared to older women (4% vs. 21%). The results for very are equally suggestive: younger women use less very in both registers but there is a sharp decline in non-narratives in particular. This suggests that innovations rise first in narratives for all speakers and then diffuse to non-narratives lead by younger women. Taken together, the findings from this study support earlier observations that greater care should be placed on the discourse embedding linguistic variation and change (see e.g., Cheshire 2005 et seq). We have demonstrated that language change actually begins and ends in stories.
Production of Octenyl Succinic Anhydride-Modified Waxy Corn Starch and Its Characterization (2008)

The objective of this work is to investigate the effects of reaction conditions on the synthesis of octenyl succinic anhydride (OSA)-modified starch from waxy corn starch and to study the characteristics of the OSA-modified starch as well as its applications. A mathematical model was developed to investigate the influences of various processing condition factors on the production of the OSA-modified waxy corn starch production and predict the optimum reaction conditions. The maximal degree of substitution (DS) of OSA-modified waxy corn starch (0.0204) was predicted to occur when the starch concentration was 31.2%, the pH was 8.6, the reaction temperature was 33.6 degrees C, and the reaction time was 18.7 h. Repeated reactions for producing OSA-modified waxy corn starch were carried out in a 5 m(3) reactor under the optimized conditions for verification of the model. The characteristics of modified waxy corn starch including infrared spectrum, scanning electron microscopy, and pasting property were tested and emulsification capacity of the OSA-modified starch were evaluated as well.
Prediction and 3D Imaging while Drilling by Drill-Bit 3D RVSP (2003)

P221 PREDICTION AND 3D IMAGING WHILE DRILLING BY DRILL-BIT 3D RVSP Abstract 1 3D imaging by drill-bit SWD data was successfully demonstrated in a first survey performed in Sicily (Italy) in 2000. However in this first survey the final 3D imaging results were achieved only after the well was completed. Following the experience of this pilot survey a second 3D RVSP was acquired in another exploration well drilled in Southern Apennines (Italy) in 2002. In this work we present the 3D imaging results obtained and used for prediction while drilling in the new 3D drill-bit RVSP application. The goal of
Incremental Subgradient Methods for Nondifferentiable Optimization (2001)

We consider a class of subgradient methods for minimizing a convex function that consists of the sum of a large number of component functions. This type of minimization arises in a dual context from Lagrangian relaxation of the coupling constraints of large scale separable problems. The idea is to perform the subgradient iteration incrementally, by sequentially taking steps along the subgradients of the component functions, with intermediate adjustment of the variables after processing each component function. This incremental approach has been very successful in solving large differentiable least squares problems, such as those arising in the training of neural networks, and it has resulted in a much better practical rate of convergence than the steepest descent method. In this paper, we establish the convergence properties of a number of variants of incremental subgradient methods, including some that are stochastic. Based on the analysis and computational experiments, the methods appear very promising and effective for important classes of large problems. A particularly interesting discovery is that by randomizing the order of selection of component functions for iteration, the convergence rate is substantially improved.

FIREMAN: a toolkit for firewall modeling and analysis (2006)

Security concerns are becoming increasingly critical in networked systems. Firewalls provide important defense for network security. However, misconfigurations in firewalls are very common and significantly weaken the desired security. This paper introduces FIREMAN, a static analysis toolkit for firewall modeling and analysis. By treating firewall configurations as specialized programs, FIREMAN applies static analysis techniques to check misconfigurations, such as policy violations, inconsistencies, and inefficiencies, in individual firewalls as well as among distributed firewalls. FIREMAN performs symbolic model checking of the firewall configurations for all possible IP packets and along all possible data paths. It is both sound and complete because of the finite state nature of firewall configurations. FIREMAN is implemented by modeling firewall rules using binary decision diagrams (BDDs), which have been used successfully in hardware verification and model checking. We have experimented with FIREMAN and used it to uncover several real misconfigurations in enterprise networks, some of which have been subsequently confirmed and corrected by the administrators of these networks.
Chronic Relapsing Multiple Sclerosis: A Case of Rapid Recovery by Application of Weak Electromagnetic Fields (1995)

A 54 year-old woman was diagnosed with multiple sclerosis (MS) in 1985 at the age of 45 after she developed diplopia, slurred speech, and weakness in the right leg. A Magnetic Resonance Imaging (MRI) scan obtained in 1985 showed several areas of plaque formation distributed in the periventricular white matter and centrum semiovale bilaterally. Coincident with slow deterioration in her condition since 1990 a second MRI scan was obtained in 1991 which showed a considerable increase in the number and size of plaques throughout both cerebral hemispheres, subcortical white matter, periventricularly and brainstem. In 1994, the patient received treatment with Interferon beta- 1b (Betaseron) for 6 months with no improvement in symptoms. However, following two successive extracranial applications of pulsed electromagnetic fields (EMFs) in the picotesla (pT) range each of 20 minutes duration the patient experienced an immediate improvement in symptoms most dramatically in gait, balance, speech, level of energy, swallowing, mood, and vision. On a maintenance program of 3 treatments per month the patient's only symptom is mild right foot and leg weakness. The report points to the unique efficacy of externally applied pT range EMFs in the symptomatic treatment of MS, indicates a lack of an association between the extent of demyelinating plaques on MRI scan and rate and extent of recovery in response to EMFs, and supports the notion that dysfunction of synaptic conductivity due to neurotransmitter deficiency particularly of serotonin (5-HT) contributes more significantly to the development of MS symptoms than the process of demyelination which clinically seems to represent an epiphenomenon of the disease.
