Some properties of robust statistics under asymmetric models
Creators: name: Wang, Jue (Jue A.)
Publisher: name: No Publisher Supplied
Year: 2008

description: Properties of robust statistics have been extensively studied in the univariate setting when the underlying model is presumed to be symmetric, and in the multivariate case when the underlying model is presumed to be elliptically symmetric. Much less attention has been given to the behavior of robust statistics under asymmetric models.  The goal of this dissertation is thus to obtain theoretical results for robust statistics under asymmetric models.  To this end, local asymmetric alternatives to symmetric and elliptically symmetric distributions are considered. A key tool used in obtaining the theories presented in this dissertation is the LeCam's lemmas on contiguity.The classes of robust univariate statistic considered here are the M-estimates, one-step version of the M-estimates, the W-estimates and the trimmed means. The classes of robust multivariate statistics considered are the M-estimates, the S-estimates, the CM-estimates and the MM-estimates, which are all treated under the unified framework of M-estimates with auxiliary scale, as well as their one-step versions. Asymptotic distributions of these statistics are obtained under local mixture models and skew-symmetric models. The asymptotic properties for the MM-estimates, even under elliptical symmetry, are the first such results for the multivariate MM-estimates.Under asymmetry, different robust statistics for location are not consistent with each other, i.e. they are estimating different notions of central tendency. Likewise, in the multivariate setting, under non-elliptical distributions, the different scatter statistics are again not consistent with each other and are reflecting different structures of the underlying distribution.  This suggests the difference in location statistics can be used to detect asymmetry and the comparison of different scatter statistics can be used to detect deviations from elliptical symmetry.Consequently, new classes of tests for symmetry and for elliptical symmetry are introduced in this dissertation based upon the comparisons of different location statistics and different scatter statistics respectively. Furthermore, the asymptotic null distributions of the proposed test statistics are derived as well as their local power functions under contiguous mixture distributions. The local power functions help provide some guidelines for choosing the proper tuning constant of the proposed tests.

description: Organic semiconductors are an attractive platform for developing chemisensors, because of their customizable surface chemistry. An understanding of the sensing mechanism would help develop surface chemistry design for molecular recognition.  We have studied the steric and chemical effects of acetone and ethanol on sublimated and spun organic films, which are used as chemisensor transducers.We designed deposition and exposure systems to study the surface current and chemistry of rubrene, pentacene, and 5,5'-bis(4-hydroxyhexylphenyl)-2,2'-bithiophene (C6) in response to acetone and ethanol vapors.  A rubrene crystal and spun film, as well as sublimated C6 and pentacene films and transistors were exposed under vacuum to saturated vapor pressure acetone gas.  The surface current was recorded in real-time, while the infrared absorption (IRAS) signature of the acetone film effect was recorded in-situ.  Some chemical interaction between acetone and the organic substrate was observed, and led to the use of saturated alkyl perfluorinated trichlorosilane (FTS) monolayer coverage of rubrene to prevent acetone degradation and removal of an amorphous spun rubrene film.  Acetone removed only 1.5% of the FTS film from saturated coverage, physisorbed multilayers of FTS on rubrene.  Besides this small chemical effect, the main effect on the sensor current is due to the physisorption of acetone itself. In the cases of pentacene and C6 sublimated films, the surface chemistry and surface current could both be measured on the same film.  Acetone intercalation into pentacene and C6 sublimated films perturbed the out-of-plane C-H bending, possibly due to steric interaction. An irreversible reduction in surface current and carrier mobility was found.  Acetone caused the thickest pentacene thin film tested (1500 Å) to produce the highest intensity differential peaks, similar to the effect of cooling the film by 3°C - 7°C.  However, cooling did not fully account for transistor current reduction.  Also, the surface chemistry response decreased upon reuse, and the surface current was not quantitatively reproducible.  This behavior may be explained by the fact that the contact adhesive was soluble in acetone.  Less surface chemical change occurred for ethanol than for acetone exposures, despite the fact that the C6 molecule has a more reactive hydroxy-hexanol termination.
Climate transitions across the cenozoic: insight from elemental ratios in benthic foraminifera and marine gastropods

description: The Cenozoic climate record derived from the oxygen isotope ratios of benthic foraminifera (δ18Ob) displays several, short term steps signifying the glaciation of Antarctica (~33.7 Ma) and the development (~2.7 Ma) and intensification (~0.9 Ma) of large-scale northern hemisphere glaciation (NHG), termed hereafter the late Pliocene transition (LPT) and mid-Pleistocene transition (MPT), respectively.  The interpretation of the δ18Ob record, which is controlled by both temperature and the oxygen isotopic composition of seawater (δω), is, however, not straightforward.  In the work presented here, I:(1) used Mg/Ca benthic foraminiferal paleothermometry paired with δ18Ob to construct high resolution records of deep ocean temperature and global ice volume to understand the underlying mechanisms of Pliocene-Pleistocene climate transitions and (2) developed a new salinity independent paleothermometer based on Sr/Ca ratios in marine gastropods and examined its potential for Cenozoic low-latitude sea surface temperature reconstructions and I constructed and applied a new regional Mg/Ca-temperature calibration based on downcore Mg/Ca variations to encompass changes in temperature and carbonate saturation in deep Atlantic Ocean. The new, high resolution bottom water temperature record from North Atlantic Deep Sea Drilling Project site 607 indicates that the deep ocean cooled across both the LPT and MPT.  The cooling across the MPT preconditioned the high latitudes for ice-sheet growth by modifying heat transport through changes in meridional temperature gradients.  Across the LPT, the mean trend in sea level decreased by 20+/-25m whereas the MPT is associated with an increase in glacial-interglacial amplitude of sea level.  I propose that the MPT is related to a change in ice sheet dynamics, specifically growth of thicker ice sheets, and that a threshold response to high-latitude cooling is not sufficient to explain the MPT.The Sr/Ca- temperature calibration study, based on the marine gastropod Conus ermineus, shows that strontium incorporation into the aragonitic gastropod shell is most likely driven by a temperature influence on growth rate.  To minimize the ontogenetic effect, I separated the Sr/Ca-temperature calibration into juvenile and adult growth stages.  The application of the new low-latitude paleothermometer to fossil specimens shows that the low latitudes cooled along with high latitudes throughout the Cenozoic.

description: There has been increasing interest in the application of neural networks to the field of finance. Several experiments have been carried out stating the success of neural networks for time series prediction.Most of the existing systems recommend single neural network architecture to be used for a particular time series. Our experiments have shown that a fixed architecture may not be the best approach across different time horizons. The thesis proposes a new methodology where multiple NARX (nonlinear autoregressive network with exogenous inputs) networks with different architectures are generated and evaluated before the beginning of a new time horizon. A network is selected from this set and employed to make predictions. This selection is based on past datasets only -- making the system completely applicable to real world scenarios.A framework of functions was built in MATLAB® to customize the Neural Network Toolbox ® for financial applications. This framework provides for all the basic functions required by a financial neural network system. An adaptive system that uses technical indicators and some external time series as inputs was built. Different rules were developed and tested for selecting the best performing neural networks.The new approach was tested on 5 currencies and the gold series. Our results show that high realized values of returns in the past, along with generalization is the best parameter to select a network for the future. A system with adaptive approach performs better than one with a fixed architecture. Our adaptive system out performed not only the fixed architectures but also other benchmarks like technical indicators, linear regression and baseline buy or sell strategies.
The faith of sacrifice: commitment and cooperation in Candomblé, an Afro-Brazilian religion

description: Religion has long been assumed to promote group cohesion and solidarity. Recent developments in evolutionary anthropology and cognitive science have begun to provide clues to the mechanisms by which this may occur. A central idea that has emerged from this literature is that costly expressions of religious commitment may serve as honest signals of cooperation toward other group members. This dissertation explores this hypothesis in the context of Candomblé, an Afro-Brazilian religion centered in Northeastern Brazil. Candomblé is organized around independent communities called terreiros, which depend on the collective efforts of their members to succeed. Belonging to Candomblé demands constant investments of time and effort from its members in terms of ritual participation. Thus, the religion presents an ideal setting to explore the relationship between religious commitment and intra-group cooperation. Quantitative and qualitative research was carried out over a period of fourteen in the city of Salvador da Bahia. Initially, a survey was conducted to understand the variability present in the population of terreiros. Although Candomblé has long been the subject of ethnographic inquiry, there is a dearth of material on the internal sociology of terreiros and the composition of their membership. The information collected during this time was essential to understand the dynamics that operate within these religious communities. In subsequent months, systematic data were collected from a sub-sample of thirteen terreiros. Instruments included a religious commitment scale designed specifically for Candomblé devotees, an individual questionnaire, and an experimental economic game. Results show that individuals who demonstrate higher levels of religious commitment cooperate more in the game and report more instances of past cooperation toward other group members. Those who provide more cooperation to others also report receiving more cooperative acts in return. In addition, those individuals who may have more to gain from group-belonging also display higher religiosity. Apart from income, other demographic variables had little effect on various measures of both religious commitment and cooperation. Results from these analyses are discussed within the framework of signaling theory and taking into account the historical, economic and social context of Candomblé.

Residence-time-fixed investigation of pressure and temperature effects on the flame synthesis of nanoparticles

Publisher: name: No Publisher Supplied
Year: 2008

description: The synthesis of nano-titania (n-TiO2) is investigated experimentally and computationally in low-pressure H2/O2/inert(s) burner-stabilized flat flames with strategic helium/argon/nitrogen dilution in a stagnation point geometry, using a metal-organic (titanium tetra-isopropoxide, TTIP) precursor.  Gas-phase simulation is applied to compute various experimental flame structures.  The employment of combinations of different molecular weight and specific heat capacity inert gases makes it possible to tailor the flame structure, so as to isolate various known parameters affecting particle growth, while maintaining fixed gas-phase residence time.  Using this method, the effects of ambient pressure and temperature are studied.  Two particle growth and evolution sub-models (i.e. a monodisperse model and a sectional model), which utilize the gas-phase modeling results, calculate the primary and aggregate particle sizes as a function of axial location in the flow field.  After deposition on a cooled substrate, the powders are characterized ex-situ using X-ray diffraction (XRD) and Brunaur-Emmet-Teller (BET) measurements to determine nanopowder characteristics, such as phase/crystallinity and specific surface area (from which primary particle size can be inferred).  This study indicates that pressure, with other parameters fixed, has limited effect on particle growth.  With identical temperature histories at 20, 30, and 40torr, the primary particle sizes vary by less than 1nm, computationally, and less than 0.8nm experimentally.  In contrast, temperature, with other parameters fixed, plays a significant role in primary particle development.  Particles generated in strategically diluted flames, with only an 80K difference in maximum temperature, have primary sizes that are more than 2.5nm different.

description: Gaseous elemental mercury (Hg0) cycling in temperate wetlands was evaluated by performing an atmospheric deposition study in addition to in situ micrometeorological and laboratory dynamic flux chamber experiments examining New Jersey salt marsh sediments.  Mercury wet deposition was measured at an urban/suburban site in eastern central New Jersey (New Brunswick) and at a rural site in northwestern New Jersey (Belvidere).  Volume-weighted mean mercury concentrations in precipitation were greater in New Brunswick (11 ng L-1) than Belvidere (8.6 ng L-1) and exhibited seasonality with highest concentrations in the summer.  Over a seven year period (1999-2002 from Zhuang 2004, plus 2003-2006 from this study), mercury concentrations in New Brunswick precipitation decreased at a rate of 0.2 µg m-2 y-1, while over a three year period (2002-2005) in Belvidere, mercury concentrations were constant.  Annual wet deposition fluxes for New Brunswick and Belvidere were 12 and 11 µg m-2 y-1 respectively, similar to previous estimates for New Jersey.  No patterns were observed between Hg and other analyzed trace metals.  Meteorological conditions also did not correlate, indicating local and regional sources.  In situ estimates of sediment-air mercury volatilization fluxes were an order of magnitude higher at the Secaucus High School Marsh (-375 to +677 ng m-2 h-1) than at the Great Bay estuary (-34 to +81 ng m-2 h-1).  Mercury volatilization fluxes were positively correlated with solar radiation at the Great Bay estuary but only on one out of six sampling days in Secaucus, potentially a result of tides.  Areally averaged annual mercury emissions from Secaucus (0.06 kg y-1) are much lower than those from industrial sources in New Jersey, but preliminary scaling up of mercury emissions estimated for the much larger Great Bay estuary (13 kg y-1) indicate that it is comparable to minor industrial sources in the State.  Laboratory flux chamber experiments showed that photochemistry is more important in sediment-air mercury volatilization than other physicochemical sediment characteristics.  In the light, mercury flux from sediments was up to 50 times larger than in the dark, with the greatest emissions observed during visible + UV treatments, as observed in the natural environment.
Tracing middle school students' understanding of probability: a longitudinal study

description: This study traces the probabilistic reasoning of five students from an urban middle school who attended an after-school mathematics enrichment program through grades 6, 7, and 8.  Case study methodology is used to describe the ways of thinking and development of ideas of these students as they were presented with open-ended tasks intended to engage them in building ideas about chance.  The tasks called for the students to investigate dice games to determine whether or not they were fair, and to devise strategies to make the games fair. Students were encouraged to discuss their ideas and justify their conjectures in small groups and with the whole class.The data for this study come from videotape records of seven after-school sessions and interviews in the Rutgers Informal Mathematics Learning project (IML) during the spring of 2004 and 2005, when the students were in grade 6 and 7.  The video data were transcribed and analyzed along with student work according to the model for studying the development of mathematical thinking proposed by Powell, Francisco, and Maher (2003).  Analysis of the data revealed that students exhibited the use of common judgmental heuristics such as representativeness, availability, and the equiprobability bias.   At least three of the students combined the representativeness heuristic with the outcome approach to create what I call the hybrid heuristic for chance events.  The application of this heuristic to assessing the fairness of games is the belief that if either player is able to win a game, then the game must be fair.  All of the students studied came to reject the idea that dice sums are equally likely.  They reached conclusions based on both classical and experimental approaches.  Each student produced a sample space or worked with a partner who did.  Though small samples were used, all of the students used experimental data to inform or provide support for their conjectures about fairness.  In grade 7, the question of whether permutations of dice outcomes should be counted as different events was raised repeatedly, and, despite persistent challenges and questions by graduate interns, the students did not change their beliefs about this issue.

description: We study aspects of supersymmetry breaking in gauge theories and string theory. On the gauge theory side, we explore metastable vacua in a SQCD-like model with an extra sector connected by a singlet. The model combines dynamical supersymmetry breaking with an O'Raifeartaigh mechanism in terms of confined variables. On the string theory side, we study the dynamics of non-supersymmetric magnetized D-brane configurations on Calabi-Yau spaces. We also study the stabilization of the supersymmetry breaking runaway quiver.

The war inside: child psychoanalysis and remaking the self in Britain, 1930-1960
Creators: name: Shapira, Michal
Publisher: name: No Publisher Supplied
Year: 2008

description: My research concerns the socio-cultural effects of war and the development of expert culture in the twentieth century. My dissertation studies this problem by exploring the impact of WW II on the conceptualization and practice of selfhood in Britain. The war elevated psychoanalysis to a position not enjoyed anywhere else in the world. Britain was a secure destination for psychoanalysts fleeing Nazism and a cosmopolitan laboratory for the development of new theories on the far-reaching meanings of total war. Under the shock of bombing and evacuation, émigré analysts like Anna Freud and Melanie Klein and native analysts like John Bowlby and Donald Winnicott were called upon to help treat men, women, and especially children. These children were key. On the one hand, they came to be seen as vulnerable and in need of protection; on the other hand, as anxious, aggressive subjects requiring control. This moment turned out to be a decisive one both for the history of psychoanalysis and for expectations for gender roles, citizenship, and the welfare state. My research has made use of the unexplored archives of British psychoanalysts, nurseries, women's groups, clinics, courts, government committees, and the BBC to trace the war's heritage. Psychoanalytic experts had a profound role in making the understanding of children and the mother-child relationship key to the creation of democratic citizenry. These professionals informed understandings not only of individuals, but also of broader political questions in the age of mass violence. By demonstrating a link between a real 'war outside' and an emotional 'war inside' they contributed to an increase in state responsibility for citizens' mental health. Historians have seldom looked at psychoanalysts other than Sigmund Freud as social actors in their cultures, leaving the histories of psychoanalytic movements' influence on European societies understudied. My research traces the work of the second generation of psychoanalysts after Freud to the horrors of total war and explores its postwar impact on both citizens and state officials. It revises the characteristic view of psychoanalysis as an elite discipline confined to the clinic, and adds to studies of history, gender, human sciences, war, and democracy.
Changing clinical presentation and outcome of acute myocardial infarction in New Jersey from 1990-2004

description: Over the past few decades, there has been a dramatic decline in coronary heart disease (CHD) mortality in the face of relatively stable incidence of acute myocardial infarction (AMI).  However, the clinical presentation of AMI has been changing with more infarcts classified as subendocardial.ObjectiveTo explore closely the change from 1990 to 2004 in the incidence and presentation of hospitalized AMI, its case fatality, and the relationship of these changes to the decline in overall CHD mortality. Design, Setting, and ParticipantsI studied hospitalized AMI cases in New Jersey from 1990-2004 (n=222,944) matched to state death records.   The ECG and enzyme presentation of AMI was examined for 1990-1993 and 2001-2004 in 416 patient hospital records. ResultsCHD mortality declined by 40.8% from 1351 to 799 per 100,000, mostly in persons without an AMI hospitalization in the preceding 4-12 years.   However, AMI hospitalization rate was relatively stable.  The QMI hospitalization rate declined by approximately 50% in every age group; in contrast, the NQMI hospitalization rate increased 2 to 3 fold in each age group. Crude in-hospital case-fatality decreased from 13.4% in 1990 to 8.8% in 2004 for QMI patients while it increased slightly for NQMI.  The 1-year case fatality of QMI decreased from 22.5% in 1990 to 17.8% in 2004 but the 1-year case fatality of NQMI patients increased from 18.3% in 1990 to 23.7% in 2004.  Hospital record reviews confirmed a substantial decrease in the frequency of ST elevation and Q wave development in AMI admissions across the study period.  A decline in cardiovascular disease (CVD) case-fatality and a marked increase in NCVD case-fatality in four years were observed.  The decline in CVD deaths might be attributed by the mix of cases which included milder MIs detected by troponins and possibly more severe cases that underwent revascularization before Q wave develop.  One of the contributors to this increasing trend in NCVD deaths might be diabetes, which is known to be associated with higher mortality for both CVD and NCVD.  The increasing prevalence of DM may play a significant role in increasing overall deaths, especially among patients following subendocardial infarction.Conclusion Changing clinical presentation of AMI and a worsening prognosis of subendocardial infarction suggest that the pathogenesis of CHD changed significantly during the 15 year study period.  The worsening prognosis of subendocardial AMI deserves attention.
Diagnosis and error correction for a fault-tolerant arithmetic and logic unit for medical microprocessors

Year: 2008

description: We present a fault tolerant Arithmetic and Logic Unit (ALU) for medical systems. Real-time medical systems possess stringent requirements for fault tolerance because faulty hardware could jeopardize human life. For such systems, checkers are employed so that incorrect data never leaves the faulty module and recovery time from faults is minimal. We have investigated information, hardware and time redundancy. After analyzing the hardware, the delay and the power overheads we have decided to use time redundancy as our fault tolerance method for the ALU.The original contribution of this thesis is to provide single stuck-fault error correction in an ALU using recomputing with swapped operands (RESWO). Here, we divide the 32-bit data path into 3 equally-sized segments of 11 bits each, and then we swap the bit positions for the data in chunks of 11 bits. This requires multiplexing hardware to ensure that carries propagate correctly. We operate the ALU twice for each data path operation -- once normally, and once swapped. If there is a discrepancy, then either a bit position is broken or a carry propagation circuit is broken, and we diagnose the ALU using diagnosis vectors. First, we test the bit slices without generating carriers -- this requires three or four patterns to exercise each bit slice for stuck at 0 and stuck-at 1 faults. We test the carry chain for stuck-at faults and diagnose their location -- this requires two patterns, one to propagate a rising transition down the carry chain, and another to propagate a falling transition. Knowledge of the faulty bit slice and the fault in the carry path makes error correction possible by reconfiguring MUXes. It may be necessary to swap a third time and recompute to get more data to achieve full error correction.The hardware overhead with the RESWO approach and the reconfiguration mechanism of one spare chunk for every sixteen chunks for the 64-bit ALU is 78%. The delay overhead for the 64-bit ALU with our fault-tolerance mechanism is 110.96%.

Genetics of schizophrenia: candidate genes and positional cloning analysis

description: Schizophrenia (SZ) is a multifactorial phenotype. Candidate gene approach and positional cloning are the primary methods for elucidating its etiology.We genotyped two TNF gene SNPs (-G308A, -G238A) and analyzed the haplotype structure in 24 Canadian families. Our results demonstrate that there is evidence for association (P=0.026) of a specific haplotype with SZ with a Trimhap test. Stratifying the 22 families with genome scan data by TNF promoter haplotypes followed by reanalysis of linkage to SZ, we identified few loci that exhibit a considerable increase in LOD/HLOD scores. A locus on chromosome 1q44 demonstrated a significant increase in LOD from 0.15 to 3.01. The synapsin 2 (Syn2) gene is implicated in synaptogenesis, neurotransmitter release, and the localization of nitric oxide synthase. 37 pedigrees of Northern European ancestry from the NIMH HGI collection were used in this study. Four microsatellites and twenty SNPs were genotyped. Linkage (FASTLINK) and association (TRANSMIT, PDTPHASE) were evaluated. A maximum HLOD of 1.93 was observed at D3S3434. Significant results were obtained for association with SZ using TRANSMIT (p=0.0000005) and PDTPHASE (p=0.014) using single marker analyses. Haplotype analysis provided a single haplotype that is significantly associated with SZ using TRANSMIT ([less than] 0.00000001) and PDTPHASE (p=0.02). The results of a linkage scan for SZ in the NIMH HGI Chinese family collection were reported by Faraone et al. with the largest NPL z score of 2.88 for D10S2327. We have reanalyzed the genome using the posterior probability of linkage (PPL). We split the sample into two subsets: those without any family members with affective diagnoses (SZ subgroup); and those with SZ, schizoaffective disorder, and bipolar disorder (HET subgroup). Genotypes were cleaned using PEDCHECK and SIMWALK. Sample specific genetic maps were constructed. SZ and HET groups were analyzed by four-point PPL analysis, and the results from each group were combined via pooling and sequential updating. The results confirmed the linkage peak on 10q22 with a PPL of 32.1% after updating. In addition we observed a peak of 30.5% over D3S1311 on 3q29 coming primarily from the HET group. Our results confirmed previous and yielded novel linkage findings in this family sample.
Performance evaluation of the cache and forward link layer protocol in multihop wireless subnetworks

description: Cache aNd Forward (CNF) is a clean-slate protocol architecture for content delivery services in the future Internet. CNF is based on the concept of store-and-forward routers with large storage, providing for opportunistic delivery to occasionally disconnected mobile users and for in-network caching of content. This thesis presents the design and evaluation of a reliable link layer protocol for CNF in context of a multi-hop wireless access network scenario. The design aims to deliver files efficiently on a hop-by-hop basis as opposed to an end-to-end approach employed by TCP/IP. CNF leverages in-network storage to store an entire file before forwarding the file to the next node. If a next hop is not currently available or has low transmission quality, files may be stored at each CNF router along the path towards the destination. In addition to the link layer protocol, end-to-end transport in CNF involves packet scheduling and routing at each network node based on cross-layer observation of link speed, MAC congestion, path length, etc. An ns-2 simulation model has been developed for a multi-hop 802.11 access network with CNF routers and a reliable link layer protocol. Baseline results for first-come-first-serve (FCFS) scheduling and shortest path routing show significant capacity gains for CNF relative to TCP for a variety of network topologies and channel models. For example, for a 49 node network with a grid topology, maximum achievable throughput with CNF was found to be 12.5 Mbps as compared to 3.9 Mbps for TCP for a scenario in which the radio links experience short-term outages with a 5% duty cycle. Preliminary results showing the value of simple cross-layer scheduling in CNF are also given in the conclusion.

description: Lung cancer is the leading cause of cancer death in the United States. The efficacy of chemotherapy in lung cancer is limited by the development of cancer cell resistance during the treatment, difficulties in the delivery of anticancer drugs specifically to lung tumors, and severe adverse side effects of high doses chemotherapy on healthy organs. The main objectives of the present research are: (1) to provide effective delivery of therapeutic and imaging agents to lungs, (2) to mitigate the above described resistance, (3) to enhance the efficacy of lung cancer chemotherapy and limit adverse side effects of the treatment. To achieve these goals, we developed, characterized, and evaluated in vitro and in vivo on orthotopic model of lung cancer using a novel multifunctional tumor-targeted Nanocarrier-based Drug Delivery System (NDDS) composed of (1) a carrier; (2) a synthetic analog of Luteinizing Hormone-Releasing Hormone (LHRH peptide) as a targeting moiety; (3) an anticancer drug or imaging agent; (4) suppressors of drug resistance. We tested and compared: linear polymer, dendrimers and liposomes as nanocarriers; antisense oligonucleotides or small interfering RNA targeted to MRP1 and BCL2 mRNA as suppressors of pump and nonpump cellular resistance respectively; near-infrared cyanine dye Cy5.5, rhodamine, or fluorescein isothiocyanate as imaging agents.  The proposed multivalent NDDS exhibited preferential accumulation in the lungs, increased the sensitivity and specificity of tumor imaging, enhanced cancer treatment, and limited adverse side effects of the treatment on healthy organs. Targeting of nanocarriers to tumor specific receptors minimizes the influence of the architecture, composition, size, and molecular mass of nanocarriers on the efficacy of imaging and cancer treatment.Local intratracheal administration sustained higher concentration of NDDS and its payload in the lungs and substantially limited their accumulation in other organs. Moreover, intratracheal local delivery of NDDS led to the more efficient treatment of lung cancer when compared with the intravenous administration of NDDS or free drugs. Simultaneous suppression of pump and nonpump resistance dramatically enhanced the cytotoxicity of the anticancer drug leading to a substantial increase in apoptosis induction.

Learning-based route management in wireless ad hoc networks

description: The nodes in a wireless ad hoc network must act as routers in a self-configuring network without infrastructure.  An application running on nodes in the ad hoc network may require that intermediate nodes act as routers, receiving and forwarding data packets to other nodes to overcome limitations of noise, router congestion and limited transmission power.  In existing routing protocols, the ``self-configuring'' aspect of network construction has generally been limited to route selection using a shortest-path routing metric as a predictor of routing efficiency.  This limited, network-layer predictor fails to consider the effects of existing traffic on router loads and fails to consider the effects of noise experienced at the MAC layer.  Not all network topologies are suited to efficient routing using a shortest-path metric.  The location of the nodes and physical characteristics of the network environment can create topologies where shortest-path routing overloads some routers and underutilizes others.  Similarly, noise sources can undermine the quality of wireless links depending on the relative distance between the noise sources and the receiving nodes.  This dissertation presents a cross-layer predictor that combines the effects of noise and router congestion into a single time-based routing metric based on statistical estimation from recent experience.  Also presented is a new cross-layer, adaptive routing protocol, called Warp-5, that not only uses the new routing metric to make better initial routing decisions in a noisy or congested network, but can also adjust previously existing routes as new routes or new noise sources are added to the network.  Simulation results for Warp-5 are presented and compared to the existing shortest-path routing protocol AODV.  The results show the cross-layer approach of Warp-5 to be superior to shortest-path routing protocols for managing router congestion and noise in wireless ad hoc networks.

Variables affecting nation-building: the impact of the ethnic basis, the educational system, industrialization and sudden shocks

description: My dissertation examines the impact of four key independent variables on nation-building, on the evolution of the spread and intensity of nationalism. An ethnic basis (language, culture, identity, etc.) similar to the desired end-product as well as the growth of education facilitate nation-building. In most cases, industrialization hinders nation-building. Sudden shocks (collapses of empires, wars and revolutions) change the intensity of nationalism scores significantly during very short periods.

Figs 1, 2, 8–13
Holotype male (MHNG), THAILAND, Rayong Province, Klaeng District, Ko Man Nai, 12°36’44”N 101°41’26”E, 5–10 m a.s.l., earth banks in mixed evergreen-deciduous forest; 18.XII.2013; P. Schwendinger leg. [THKH-13/02].
Etymology. The specific name is a noun in apposition referring to the type locality.
Diagnosis. Based on the palpal conformation, the new species is most similar to the Thai A. siama Tanasevitch, 2014, known from the male (Tanasevitch 2014b), but can be distinguished by a egg-shaped palpal tibia, by a narrower embolus, in which an exfoliated tunic distally is divided into several parts, as well as by a thicker paracymbium which lacks a tubercle in its middle part. The shape of the palpal tibia and the embolic division resembles that of A. perforata Tanasevitch, 2014 and A. signifera Tanasevitch, 2014, both described from Laos (Tanasevitch 2014a). From the former, A. komannai n. sp. differs by the absence of a large pit on both sides of the carapace; from the later, by the shape of the exfoliate tunic of the embolus, which in A. signifera resembles a “flag”.
Description. Male holotype. Rather large Erigoninae, total length 2.08. Carapace 0.90 long, 0.70 wide, pale brown; head part slightly elevated (Fig. 2) and somewhat lighter than overall carapace colour. Chelicerae unmodified, 0.38 long. Legs pale brownish yellow. Leg I, 3.73 long (0.95+0.25+0.95+0.95+0.63), IV, 3.34 long (0.88+0.23+0.85+0.88+0.50). Chaetotaxy 2.2.1.1, length of spines about 1–2 diameters of segment. All metatarsi with a trichobothrium. TmI, 0.36. Palp (Figs 8–13): Tibia relatively small, oval. Paracymbium L-shaped. Distal suprategular apophysis flat, curved, with a hollow in middle part, abruptly truncate apically. Median membrane well-developed, protruding far beyond palp. Radical part of embolic division small, drop-shaped, surrounded by membranous tissue around which connects the convector to the radix. Convector flat, crescent-shaped, with its outer margin folded forming a gutter to sheath the distal part of the embolus; distal part of convector claw-shaped. Embolus long, forming a loop, distal half embedded inside convector. Distal part of embolus showing an exfoliate tunic leaving the distal half of the embolus proper free, whip-shaped. Abdomen 1.18 long, 0.78 wide, grey dorsally, with a pale longitudinal stripe.
Female. Unknown.
Distribution. Only known from the type locality, a tiny island off the coast of eastern Thailand.

From Hiroshima to the hydrogen bomb:  American artists witness the birth of the atomic age
Creators: name: Rompilla, Denise M.
Publisher: name: No Publisher Supplied
Year: 2008

description: This dissertation investigates the visual legacy of the atomic bomb as viewed through the eyes of a distinct set of witnesses, American artists who came into contact with the physical and psychological after-effects of the bomb from the atomic attacks on Hiroshima and Nagasaki in 1945, through the years leading up to the implementation of the partial test-ban treaty in 1963.  While technical jargon, metaphorical language, and jingoistic sentiment all helped to shape public attitudes about the bombings, the visual condensation of the atomic experience into a single image, that of the mushroom cloud, offered a limited perspective of the bomb's unique capacity for destruction.  Censorship of photographs of Hiroshima and Nagasaki shielded the public from troubling images of victims on the ground.  Unseen dangers, such as lingering radiation at the bomb sites, as well as the creeping global menace of nuclear fallout from atmospheric testing, were difficult to communicate through visual media.  The escalation of the arms race between the United States and Russia gave birth to existential dread over the unimaginable consequences of a large-scale nuclear war.  Living in the shadow of the bomb, a handful of American artists turned to an interpretative visual language to give form to a terror of dimensions impossible to assimilate.  Acknowledging that the scope and brutality of destruction of World War II had reshaped their vision of the world, these artists rejected conventional imagery as simply inadequate to represent the uncertain realities of the postwar era.  But rather than adopt a language of abstraction that could be loosely interpreted as a reverberation of the anxiety of those years, instead, these artists applied expressive visual styles to highly-charged subject matter that sought to address, head-on, the human fallout of America's experimentations with the bomb.  In a broader sense, this dissertation is an investigation into what it means to be a witness to the first atomic age, both in the historical sense, of being present at critical events in the timeline of nuclear development; and in the ethical sense, of being compelled to bear witness to the use, testing, and proliferation of nuclear weapons.
