Sensor data fusion on a parallel processor (1986)

A major obstacle to the implementation of an intelligent, multi-sensor integrated robotic system is the lack of a uniform environment for developing the diverse system components and for efficiently communicating between these components. Our work is concerned with the solution through mapping such system onto a single parallel processor. We present a graphical programming environment, the Function Network Programming Environment, for developing and hierarchically organizing the computational modules of complex, asynchronous systems. In this environment, dependencies between modules are described graphically by interconnected function nodes; hence, parallelism is expressed naturally. Implementation on the BBN Butterfly parallel processor is also discussed, and a hypothetical development cycle for a multi-sensor integrated robot is described. It is expected that this environment will greatly facilitate the design and development of sophisticated, multi-sensor integrated robotic systems as well as enhance human comprehension of such systems.
Association of a Serotonin Transporter Polymorphism (5-HTTLPR) With Depression, Perceived Stress, and Norepinephrine in Patients With Coronary Disease: The Heart and Soul Study (2007)

Among patients with chronic illness, carriers of the s allele of 5-HTTLPR are more vulnerable to depression, perceived stress, and high norepinephrine secretion. These factors may contribute to worse cardiovascular outcomes in these patients.
Fukushima in review: A complex disaster, a disastrous response (2012)

On March 11, 2011, an earthquake and tsunami crippled the Fukushima Daiichi Nuclear Power Station. The emerging crisis at the plant was complex, and, to make matters worse, it was exacerbated by communication gaps between the government and the nuclear industry. An independent investigation panel, established by the Rebuild Japan Initiative Foundation, reviewed how the government, the Tokyo Electric Power Company (Tepco), and other relevant actors responded. In this article, the panel’s program director writes about their findings and how these players were thoroughly unprepared on almost every level for the cascading nuclear disaster. This lack of preparation was caused, in part, by a public myth of “absolute safety” that nuclear power proponents had nurtured over decades and was aggravated by dysfunction within and between government agencies and Tepco, particularly in regard to political leadership and crisis management. The investigation also found that the tsunami that began the nuclear disaster could and should have been anticipated and that ambiguity about the roles of public and private institutions in such a crisis was a factor in the poor response at Fukushima.
The Corneal Epithelial Basement Membrane: Structure, Function, and Disease (2013)

The corneal epithelial basement membrane (BM) is positioned between basal epithelial cells and the stroma. This highly specialized extracellular matrix functions not only to anchor epithelial cells to the stroma and provide scaffolding during embryonic development but also during migration, differentiation, and maintenance of the differentiated epithelial phenotype. Basement membranes are composed of a diverse assemblage of extracellular molecules, some of which are likely specific to the tissue where they function; but in general they are composed of four primary components--collagens, laminins, heparan sulfate proteoglycans, and nidogens--in addition to other components such as thrombospondin-1, matrilin-2, and matrilin-4 and even fibronectin in some BM. Many studies have focused on characterizing BM due to their potential roles in normal tissue function and disease, and these structures have been well characterized in many tissues. Comparatively few studies, however, have focused on the function of the epithelial BM in corneal physiology. Since the normal corneal stroma is avascular and has relatively low keratocyte density, it is expected that the corneal BM would be different from the BM in other tissues. One function that appears critical in homeostasis and wound healing is the barrier function to penetration of cytokines from the epithelium to stroma (such as transforming growth factor β-1), and possibly from stroma to epithelium (such as keratinocyte growth factor). The corneal epithelial BM is also involved in many inherited and acquired corneal diseases. This review examines this structure in detail and discusses the importance of corneal epithelial BM in homeostasis, wound healing, and disease.
Composite sol-gel alumina ceramic/siloxane coatings (2009)

This thesis relates to the novel, relatively low temperature process (160-300°C) for preparation of chemically bonded composite sol-gel (CB-CSG) coatings. This "warm" temperature process (160-300°C) overcomes some drawbacks of the conventional composite sol-gel process, in particular minimization of stresses due to differential thermal expansion coefficient between the coating and the substrate. The biggest contribution o f this research involves use of siloxane bond coat between the CBCSG coating and the mild steel substrate, which relaxes residual stress in the coating, as well as protects the substrate from damage (corrosion) during the chemical bonding process. A method of multi-gun spraying to uniformly distribute the phosphates throughout the coating during the chemical bonding process is also an original contribution of this Thesis. The resulting coatings are free of surface cracks, have medium hardness (6.0GPa), moderate adhesion (42.0MPa) and good scratch resistance (17.0kgf). Electrochemical analysis shows that the multi-layer coating composed of the siloxane bond coat and the CB-CSG "top coat" forms a physical barrier against wet corrosion.
Synthesis and rearrangement reactions of dihalogenotris- and dihalogenotetrakis-(tertiary phosphine)ruthenium(II) compounds (1975)

The reactions of [RuCl2(PPh3)4] with several tertiary phosphine ligands in various solvents have been examined. Whereas prolonged reaction in ethanol or dichloromethane leads to the well known ionic dimers [Ru2Cl3L6]Cl(L = PEtPh2, PEt2Ph, or PMe2Ph), reaction in non-polar solvents such as hexane or light petroleum (b.p. 60–80 °C) produces neutral complexes. For L = PEtPh2, [RuCl2(PEtPh2)3] has been isolated although this readily converts to the triple chloride-bridged dimer [(Ph2EtP)3RuCl3RuCl(PEtPh2)2] in non-polar and [Ru2Cl3(PEtPh2)3]Cl in polar media. For L = PEt2Ph and PClPh2, only [L3RuCl3RuClL2] can be isolated although 31P n.m.r. studies indicate the presence of [RuCl2(PEt2Ph)3] in the reaction mixture. For L = PMe2Ph, cis-[RuCl22(PMe2Ph)4] is formed although this very readily rearranges to [Ru2Cl3(PMe2Ph)6]Cl. Preliminary studies indicate that similar compounds are formed from [RuBr2(PPh3)4]. All these compounds {including [RuCl2(PPh3)3 and 4]} have been extensively studied by variable-temperature 31P n.m.r. spectroscopy and an overall mechanism for the rearrangement reactions of all tertiary phosphine complexes of type [RuX2L3 or 4] is proposed.

A Robotic Auto-Focus System based on Deep Reinforcement Learning (2018)

Considering its advantages in dealing with high-dimensional visual input and learning control policies in discrete domain, Deep Q Network (DQN) could be an alternative method of traditional auto-focus means in the future. In this paper, based on Deep Reinforcement Learning, we propose an end-to-end approach that can learn auto-focus policies from visual input and finish at a clear spot automatically. We demonstrate that our method - discretizing the action space with coarse to fine steps and applying DQN is not only a solution to auto-focus but also a general approach towards vision-based control problems. Separate phases of training in virtual and real environments are applied to obtain an effective model. Virtual experiments, which are carried out after the virtual training phase, indicates that our method could achieve 100% accuracy on a certain view with different focus range. Further training on real robots could eliminate the deviation between the simulator and real scenario, leading to reliable performances in real applications.
An Empirical Study of Probability Elicitation Under Noisy-OR Assumption. (2004)

Bayesian network is a popular modeling tool for uncertain domains that provides a compact representation of a joint probability distribution among a set of variables. Even though Bayesian networks significantly reduce the number of probabilities required to specify probabilistic relationships in the domain, the number of parameters required to quantify large models is still a serious bottleneck. Further reduction of parameters in a model is usually achieved by utilization of parametric probability distributions such as noisy-OR gates. In this paper report the results of an empirical study that suggests that under the assumption, that the underlying modeled distribution follows the noisy-OR assumptions, human experts provide parameters with better accuracy using elicitation of noisy-OR parameters than when eliciting conditional probability tables directly. It also seems that of the two alternative noisy-OR parameterizations due to Henrion and Díez the latter results in better elicitation accuracy.
Human platelet thermostable phenol sulfotransferase from blacks and whites: biochemical properties and variations in thermal stability. (1988)

Phenol sulfotransferase (PST) catalyzes the sulfate conjugation of catecholamines and of phenolic drugs. Human platelet PST exists in at least a thermolabile form (TL PST) and a thermostable form (TS PST). The mean basal level of platelet TS PST activity in samples from American blacks is significantly higher than the basal activity in samples from whites. We carried out the studies reported here to determine whether the higher basal TS PST activity in platelet homogenates from blacks was biochemically similar to the lower basal activity in samples from whites. We also characterized variations in TS PST thermal stability. Platelet TS PST activities in samples from the two groups were almost identical with respect to pH optima, Michaelis-Menten constant values for substrates, and susceptibilities to inhibition by 2,6-dichloro-4-nitrophenol and sodium chloride. Thermolabile and thermostable TS PST were present in samples from both blacks and whites. Thermal stabilities of TS PST in samples from 167 volunteers (104 blacks, 63 whites) were expressed as heated sample-to-control sample ratios. Bimodal frequency distribution histograms of the heated-to-control ratios revealed subgroups of samples with thermolabile TS PST activities from 13.5% of blacks (heated-to-control ratio less than 0.32) and 12.7% of whites (heated-to-control ratio less than 0.27). The mean heated-to-control ratio for thermostable TS PST from blacks was significantly higher than that from whites (0.52 +/- 0.01 vs 0.43 +/- 0.01, respectively, mean +/- SEM; p less than 0.0001). Our studies demonstrated the similarity of biochemical properties of platelet TS PST at the extremes of basal activity. They also showed equivalent subgroups of blacks and whites with thermolabile TS PST. The results are an important initial step toward testing the hypothesis that inheritance may be one factor in the regulation of basal levels of activities and thermal stabilities of platelet TS PST from American blacks.

Essays on Random Forest Ensembles (2018)

A random forest is a popular machine learning ensemble method that has proven successful in solving a wide range of classification problems. While other successful classifiers, such as boosting algorithms or neural networks, admit natural interpretations as maximum likelihood, a suitable statistical interpretation is much more elusive for a random forest. In the first part of this thesis, we demonstrate that a random forest is a fruitful framework in which to study AdaBoost and deep neural networks. We explore the concept and utility of interpolation, the ability of a classifier to perfectly fit its training data. In the second part of this thesis, we place a random forest on more sound statistical footing by framing it as kernel regression with the proximity kernel. We then analyze the parameters that control the bandwidth of this kernel and discuss useful generalizations.
Fire-setting on an adolescent inpatient unit: an analysis. (1980)

A one time series of fire-setting episodes on an inpatient adolescent service are analyzed from a systems standpoint for the purpose of primary prevention. This paper documents that fire-setting behavior can occur in individuals with no prior history of fire-setting and that losses to the hospital system proper can be psychologically coupled to losses felt by an individual. Specific recommendations are offered based on both case history analysis of the protagonists and the psychosocial determinants of the hospital system. A selective literature review compares this experience with others.
Regioselective Stepwise Growth of Dendrimer Units in the Internal Voids of a Main Dendrimer (1997)

Dendrimers constitute a class of polymers with unique properties and applications resulting from the presence of internal voids and of a large number of functionalities on the surface. The development of a macromolecular chemistry within the cavities of dendrimers is illustrated here. Two examples of construction of six dendrimer units within the cascade structure of a main dendrimer are reported. The preparation of these multidendritic systems involves the regioselective modification of the framework of the central dendrimer to create internal reactive centers, followed by the stepwise synthesis of the six dendritic macromolecules.
Is there a ‘weight neutral’ second-generation antipsychotic for bipolar disorder? (2016)

Antipsychotic-induced weight gain (WG) and metabolic abnormalities are major concerns. This review was untaken to answer if there is a weight-neutral second-generation antipsychotic for bipolar disorder (BPD). Areas covered: English-language literature in MEDLINE was searched with the keywords of antipsychotic/second-generation antipsychotic or generic/brand name of second-generation antipsychotic, and BPD/mania/depression or bipolar maintenance, and safety/tolerability or WG/weight increase, and randomized, placebo-controlled trial. Difference between an antipsychotic monotherapy and placebo in absolute weight gain (AWG) and/or ≥ 7% (WG in three phases of BPD was compared based on the data from original publications. The number needed to treat to harm was used for the comparison of ≥ 7% WG. Among antipsychotics with short-term (mania and/or bipolar depression) and long-term (maintenance) studies, olanzapine, asenapine, quetiapine, risperidone had significant WG compared to placebo in both short-term and long-term trials. Aripiprazole did not cause significant WG compared to placebo in short-term studies, but caused significant WG in long-term studies. Paliperidone-ER-induced WG was significant in a mania study as measured with AWG, and ziprasidone caused significant WG in a mania study measured with ≥ 7% WG. Expert commentary: These data suggest that it is unlikely there is a weight-neutral second-generation antipsychotic in BPD.

Simulation based approach to study the interaction of scheduling and routing on a logistic network (1997)

This research investigates the interaction of production scheduling and routing/transportation on a logistic network. Basic scheduling rules and existing routing/transportation alternatives were studied using a simulation model, with cost and customer service levels as measures of performance. The simulation model, including network configuration, orders, service times, etc., was based on a "real world" electronic manufacturer, where the production process requires components to flow through three facilities. The two existing routing/transportation alternatives are ocean and air freight. The analysis of the results indicated that certain combinations of scheduling and routing rules result in low manufacturing-logistic costs while maintain high levels of customer service.
Vitiligo Area Scoring Index and Vitiligo European Task Force assessment: reliable and responsive instruments to measure the degree of depigmentation in vitiligo (2014)

VASI and VETFa are reliable and responsive instruments to assess the degree of depigmentation in vitiligo. VASI and VETFa for depigmentation are potential instruments for vitiligo research in the future. However, for use in individual patient care, caution is needed when interpreting score changes in individual patients because of the relatively large SDC.
Fabrication of metal nanowires by atomic force microscopy nanoscratching and lift-off process (2005)

A convenient method for the fabrication of metal nanowires by a combination of atomic force microscopy nanoscratching on a single-layer resist and lift-off process is reported. Various metal nanowires, including Au, Cu, Ni, Al, and Ti, with widths as small as 50 nm are successfully created. The electrical resistivities of the nanowires have also been obtained and found to be in good agreement with reported results.
Non-Enzymatic Depurination of Nucleic Acids: Factors and Mechanisms (2014)

Depurination has attracted considerable attention since a long time for it is closely related to the damage and repair of nucleic acids. In the present study, depurination using a pool of 30-nt short DNA pieces with various sequences at diverse pH values was analyzed by High Performance Liquid Chromatography (HPLC). Kinetic analysis results showed that non-enzymatic depurination of oligodeoxynucleotides exhibited typical first-order kinetics, and its temperature dependence obeyed Arrhenius' law very well. Our results also clearly showed that the linear relationship between the logarithms of rate constants and pH values had a salient point around pH 2.5. Interestingly and unexpectedly, depurination depended greatly on the DNA sequences. The depurination of poly (dA) was found to be extremely slow, and thymine rich sequences depurinated faster than other sequences. These results could be explained to some extent by the protonation of nucleotide bases. Moreover, two equations were obtained based on our data for predicting the rate of depurination under various conditions. These results provide basic data for gene mutagenesis and nucleic acids metabolism in acidic gastric juice and some acidic organelles, and may also help to rectify some misconceptions about depurination.
Policy Management as a Service: An Approach to Manage Policy Heterogeneity in Cloud Computing Environment (2012)

Security issues are delaying fast adoption of cloud computing and security mechanisms to ensure its secure adoption has become a crucial immediate need. On the other hand, cloud computing can help enable security controls to be delivered in new ways by service providers. To this end, we need frameworks for efficient delivery of cloud-based security services and for provisioning desirable solutions to customers based on their requirements. In this paper, we focus on policy management systems in cloud environments. Currently, users must use diverse access control solutions available for each cloud service provider to secure data. Access control policies may be composed in incompatible ways because of diverse policy languages that are maintained separately at every cloud provider. Heterogeneity and distribution of these policies pose problems in managing access policy rules for a cloud environment. In this paper, we introduce Policy Management as a Service (PMaaS), a cloud based policy management framework that is designed to give users a unified control point for managing access policies to control access to his resources no matter where they are stored. We present the framework and describe its components and protocols needed for various components to communicate.
The Lifetime Estimate for ACSR Single-Stage Splice Connector Operating at Higher Temperatures (2011)

The power transmission conductor system consists of: the aluminum conductor, the steel-core supporting material, and the splice connector. The splice connector connects the aluminum conductor to form a continuing current transmission line. The splice connector region of a conductor system is more sensitive to material aging during service. This is due to the material discontinuity and the crimped connector's forming mechanism. The objective of this project is to develop a protocol to evaluate the integrity of a full tension single-stage splice connector (SSC) assembly operated at high temperature. The project focuses on thermal mechanical testing, thermal cycling simulation and the effective lifetime of the SSC system. The investigation indicates that thermal cycling temperature and frequency, conductor cable tension loading, and the compressive residual stress field within a SSC system have significant impact on SSC integrity and its associated effective lifetime. The developed governing equation and its application to assure the adequate service life of transmission lines are also discussed in the paper.
