An implementation of a data-transmission pipelining algorithm on Imote2 platforms

Over the past several years, wireless network systems and sensing technologies have been developed significantly. This has resulted in the broad application of wireless sensor networks (WSNs) in many engineering fields and in particular structural health monitoring (SHM). The movement of traditional SHM toward the new generation of SHM, which utilizes WSNs, relies on the advantages of this new approach such as relatively low costs, ease of implementation and the capability of onboard data processing and management. In the particular case of long span bridge monitoring, a WSN should be capable of transmitting commands and measurement data over long network geometry in a reliable manner. While using single-hop data transmission in such geometry requires a long radio range and consequently a high level of power supply, multi-hop communication may offer an effective and reliable way for data transmissions across the network. Using a multi-hop communication protocol, the network relays data from a remote node to the base station via intermediary nodes. We have proposed a data-transmission pipelining algorithm to enable an effective use of the available bandwidth and minimize the energy consumption and the delay performance by the multi-hop communication protocol. This paper focuses on the implementation aspect of the pipelining algorithm on Imote2 platforms for SHM applications, describes its interaction with underlying routing protocols, and presents the solutions to various implementation issues of the proposed pipelining algorithm. Finally, the performance of the algorithm is evaluated based on the results of an experimental implementation.
A G protein/cAMP signal cascade is required for axonal convergence into olfactory glomeruli

The mammalian odorant receptors (ORs) comprise a large family of G protein-coupled receptors that are critical determinants of both the odorant response profile and the axonal identity of the olfactory sensory neurons in which they are expressed. Although the pathway by which ORs activate odor transduction is well established, the mechanism by which they direct axons into proper glomerular relationships remains unknown. We have developed a gain-of-function approach by using injection of retroviral vectors into the embryonic olfactory epithelium to study the ORs′ contribution to axon guidance. By ectopically expressing ORs, we demonstrate that functional OR proteins induce axonal coalescence. Furthermore, ectopic expression of Gα mutants reveals that activation of the signal transduction cascade is sufficient to cause axonal convergence into glomeruli. Analysis of Gα subunit expression indicates that development and odorant transduction use separate transduction pathways. Last, we establish that the generation of cAMP through adenylyl cyclase 3 is necessary to establish proper axonal identity. Our data point to a model in which axonal sorting is accomplished by OR stimulation of cAMP production by coupling to Gαs.
Vibrational Spectroscopy of Na–H Complexes in ZnO

Sodium acceptors were diffused into ZnO bulk single crystals to a depth of ~1μm, with a near-surface concentration of ~1018–cm3. An O–H local vibrational mode (LVM) was observed at 3304–cm–1, at a temperature of 9 K, in hydrogenated samples. The LVM is attributed to an O–H bond-stretching mode adjacent to a Na acceptor. When deuterium substitutes for hydrogen, a peak is observed at 2466–cm–1. The isotopic frequency ratio is similar to values found in other hydrogen complexes. In the deuterated sample, a sideband at 2461–cm–1 is attributed to a Fermi resonance.
Creating an automated chiller fault detection and diagnostics tool using a data fault library.

Abstract Reliable, automated detection and diagnosis of abnormal behavior within vapor compression refrigeration cycle (VCRC) equipment is extremely desirable for equipment owners and operators. The specific type of VCRC equipment studied in this paper is a 70-ton helical rotary, air-cooled chiller. The fault detection and diagnostic (FDD) tool developed as part of this research analyzes chiller operating data and detects faults through recognizing trends or patterns existing within the data [1]. The FDD method incorporates a neural network (NN) classifier to infer the current state given a vector of observables. Therefore the FDD method relies upon the availability of normal and fault empirical data for training purposes and therefore a fault library of empirical data is assembled [2]. This paper presents procedures for conducting sophisticated fault experiments on chillers that simulate air-cooled condenser, refrigerant, and oil related faults. The experimental processes described here are not well documented in literature and therefore will provide the interested reader with a useful guide. In addition, the authors provide evidence, based on both thermodynamics and empirical data analysis, that chiller performance is significantly degraded during fault operation. The chiller's performance degradation is successfully detected and classified by the NN FDD classifier as discussed in the paper's final section.
Potential magnitude of future vegetation change in eastern north america: comparisons with the past.

Increases in atmospheric trace gas concentrations could warm the global average temperature 1.5° to 4.5°C by the end of the next century. Application of climate-pollen response surfaces to three climate model simulations of doubled preindustrial atmospheric CO 2 levels shows that the change in the equilibrium distribution of natural vegetation over eastern North America over the next 200 to 500 years could be larger than the overall change during the past 7,000 to 10,000 years and equivalent to the change that took place over the 1,000- to 3,000-year period of most rapid deglaciation. Some plant ranges and abundance maxima could shift as much as 500 to 1000 km during the next 200 to 500 years; such changes would have dramatic impacts on silvicultural and natural ecosystems. Although unprecedented vegetation change is likely if climate changes as predicted, forecasting the exact timing and patterns of change will be difficult.
The radiologic appearance of solitary pulmonary nodules and their cytologic-histologic correlation

In this article, we review the various causes of solitary pulmonary nodules. Based on the underlying histology, we attempt to account for the radiologic pattern associated with each. This includes features related to density, edge characteristics, and texture. Similarly, the radiologic appearance of the nodule can be helpful to the cytologist when interpreting cytological samples obtained through image guidance.
Exponents of class groups and elliptic curves

We show that the number of elliptic curves over Q with conductor N is ⪡e N1/4+e, and for almost all positive integers N, this can be improved to ⪡e Ne. The second estimate follows from a theorem of Davenpart and Heilbronn on the average size of the 3-class groups of quadratic fields. The first estimate follows from the fact that the 3-class group of a quadratic field Q(D) has size ⪡e |D|1/4+e, a non-trivial improvement over the Brauer–Siegel estimate.
Neural pattern identification of railroad wheel-bearing faults from audible acoustic signals: comparison of FFT, CWT, and DWT features

Current railroad wayside Hot Bearing Detector systems were developed in the 1960s to identify failing friction bearings. While the electronics used in these systems have been upgraded to microprocessor technology, the basic detection principles have not changed over the last 30 years. In this paper, we present a novel method to detect, recognize, and classify a variety of railroad wheel-bearing defects using audible acoustic signals at several different train speeds. Our algorithm consists of a data preprocessor, a feature extractor, and a single multilayer neural network. The feature extractor can use any one of four different transforms to generate feature vectors from input acoustic data: the fast Fourier transform (FFT), the continuous wavelet transform, the discrete wavelet transform, and the wavelet packet. The classification performance using each feature vector type is presented. This algorithm can be applied to many kinds of bearings in rotational machinery to perform nondestructive fault detection and identification.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.

Rural-Urban Differences in Health Insurance Coverage and Patterns Among Working-Age Adults in Kentucky

Context: Past studies show that rural populations are less likely than urban populations to have health insurance coverage, which may severely limit their access to needed health services. Purpose: To examine rural-urban differences in various aspects of health insurance coverage among working-age adults in Kentucky. Methods: Data are from a household survey conducted in Kentucky in 2005. The respondents include 2,036 individuals ages 18-64. Bivariate analyses were used to compare the rural-urban differences in health insurance coverage by individual characteristics. Logistic regression analyses were used to examine the independent impact of rural-urban residence on the various aspects of health insurance coverage, while controlling for the individuals’ health status and sociodemographic characteristics. Findings: The overall rate of working-age adults with health insurance did not differ significantly between the rural and urban areas of Kentucky. However, there were significant rural-urban differences in insurance for specific types of health care and in patterns of insurance coverage. Rural adults were less likely than urban adults to have coverage for vision care, dental care, mental health care, and drug abuse treatment. Rural adults were also less likely to obtain insurance through employment, and their current insurance coverage was, on average, of shorter duration than that of urban adults. Conclusions: In Kentucky, the overall health insurance rate of working-age adults is influenced more by employment status and income than by whether these individuals reside in rural or urban areas. However, coverage for specific types of care, and coverage patterns, differ significantly by place of residence.
Cardiovascular effects of microinjections of angiotensin II into the nucleus tractus solitarii.

The role of the angiotensin II system within the nucleus tractus solitarii (NTS) in central cardiovascular control was investigated by local microinjections of angiotensin II and the angiotensin II receptor antagonist saralasin. Microinjections of 1 ng angiotensin II into the NTS resulted in a monophasic depressor response (−7.3 ± 1.7 mm Hg), while higher doses were characterized by a biphasic response, with an initial decrease followed by a subsequent increase in blood pressure (10 ng: −4.7 ± 1.3/+ 7.9 ± 1.1 and 100 ng: −2.4 ± 1.2/+ 7.5 ± 1.2 mm Hg). Heart rate decreased significantly following microinjections of 1 and 10 ng angiotensin II (−27 ± 5.0 and −15 ± 5.9 bpm), while with 100 ng angiotensin II there was no significant effect on heart rate. Prior i.v. administration of atropine (1 mg/kg) abolished the bradycardia, but did not significantly affect the blood pressure response. Microinjections of saralasin into the NTS elicited a dose-dependent pressor response (10 ng: 6.0 ± 1.5 mm Hg; 100 ng: 16.8 ± 3.4 mm Hg) and tachycardia (10 ng: 5 ± 3.2 bpm; 100 ng: 17 ± 4.4 bpm). Our data support the hypothesis that angiotensin II acts on specific receptors within the NTS to modulate peripheral cardiovascular responses. The cardiovascular effects elicited by microinjections of the peptide exhibit complicated dose-response relationships. The effects on heart rate, but not on blood pressure, appear to be mediated by parasympathetic activation.
Biosynthesis of phenylquinolizidine alkaloids by Heimia salicifolia

Abstract Incorporation studies of the known heimia alkaloid precursors [ 3 H]lysine/[ 14 C]phenylalanine into the three types of alkaloids, phenylquinolizidinols, phenylquinolizidinyl p -coumarates and biphenylquinolizidine lactones, produced by in vitro -grown Heimia salicifolia indicate that whereas within an alkaloid type both the cis -fused and trans -fused alkaloids originate from a common metabolic pool, the three types of alkaloids are formed from different precursor pools. The data suggest that the biphenylquinolizidine lactones are derived from neither the phenylquinolizidinols nor the ester alkaloids that accumulate in the cultures. Studies with [ 3 H]lysine/[ 14 C] p -coumaric acid confirm these findings and further indicate that p -coumaric acid is a precursor to both the phenylquinolizidinyl- and the p -coumaroyl group of the alkaloids.
An arc floating zone technique for preparing single crystal lanthanum hexaboride

An arc floating zone technique has been developed for producing LaB6. The technique consistently produces single crystals which nucleate and grow with essentially random crystallographic orientations. Chemical analyses show that very effective purification is obtained, contamination from the tantalum electrode material does not occur, and stoichiometry of the LaB6 is maintained.
Effects of Progesterone on Male-Mediated Infant-Directed Aggression

Many species that engage in parental behavior exhibit infanticide under certain circumstances. The neural signals regulating the transition from infant care giver to infant killer and back remain unclear. Previously we demonstrated that progesterone (P) and its receptor (PR) have inhibitory effects on parental behavior and increase infant-directed aggression in male mice. In the present studies we sought to elucidate the mechanisms by which the effects of P are manifested. Because the onset of parental behavior in females is associated with the withdrawal of P at the end of pregnancy we tested the hypothesis that withdrawal of P would similarly enhance parental behavior in males. Virgin male mice were implanted with P or vehicle for 21 days, replicating the duration of pregnancy in females. Tests were run for parental and infanticidal behavior 5 days after removal of the capsules. P increased the proportion of nonparental males that attacked pups. However, neither the number of males exhibiting parental care nor the quality of care was affected by P treatment. Serum P and testosterone (T) levels were not different from controls at the time of behavioral testing indicating continued elevations in peripheral hormones are not required for the expression of infanticide. In conclusion, withdrawal of P does not trigger the onset of parental behavior in males. Rather, prior exposure to P induces persistent infanticidal behavior in adult male mice.
Future immunosuppressive agents in solid-organ transplantation.

Objective—To review the pharmacology, pharmacokinetics, efficacy, and safety of mycophenolate sodium, everolimus, and FTY720.Study Selection and Data Extraction—Clinical trials and abstracts evaluating mycophenolate sodium, everolimus, and FTY720 in solid-organ transplantation were considered for evaluation. English-language studies and published abstracts were selected for inclusion.Data Synthesis—Mycophenolate sodium has recently been approved by the Food and Drug Adminstration for marketing in the United States; everolimus and FTY720 are immunosuppressive agents that may soon be available in the United States. These agents have proven efficacy in reducing the incidence of acute rejection in solid-organ transplantation. Clinical trials have shown that these newer agents are relatively well tolerated. The most common adverse events associated with these agents were gastrointestinal and hematologic effects (mycophenolate sodium); hyperlipidemia, increased serum creatinine, and hematologic effects (everoli...
Five Years after the 2002 Denali Fault Earthquake Sequence: A Regional Network Operator's Perspective

We have passed the fifth anniversary of the 2002 Denali fault, Alaska, earthquake sequence. At this point it is worthwhile to look back and reflect on our experience with the event at the Alaska Earthquake Information Center (AEIC). The earthquake sequence started with the magnitude 6.7 earthquake on 23 October 2002. While no surface rupture was found during the aerial survey of the epicentral area, it very quickly became clear that this earthquake ruptured one of the most significant tectonic features in Alaska, the Denali fault (figure 1). While this event was widely felt throughout central Alaska, it did not cause significant damage. Following this event, AEIC installed a network of temporary seismometers to monitor the aftershock activity. This was a fortuitous action because a much larger earthquake, of magnitude 7.9, initiated just east of the mag nitude 6.7 event 10 days later on 3 November 2002. The temporary instruments provided valuable near-field recordings of the mainshock and of the early aftershocks. ▴ Figure 1. Recorded earthquakes (depth < 30 km) in the vicinity of the 2002 Denali fault earthquake sequence that occurred between …
The Complex Lives of Disconnected Welfare Leavers: Examining Employment Barriers, Social Support and Informal Employment

With no federal entitlement to cash assistance, some unemployed welfare leavers have no obvious means of support. This article compares former Louisiana's Strategies to Empower People (STEP) participants who are disconnected from employment and Temporary Assistance for Needy Families (TANF) to those who are connected. Logistic regressions show that disconnected welfare leavers are more likely to have transportation problems, live rent free, and engage in informal employment. They are less likely to report a health problem or have a child with poor health, share living expenses, or receive cash help from family and friends. Contributions to the literature and policy initiatives are discussed.
Embedding partial extended triple systems and totally symmetric quasigroups

Abstract In this paper, we show that any partial extended triple system (partial totally symmetric quasigroup) of order n can be embedded in a totally symmetric quasigroup of order v , v ⩾ 4 n + 6, v  2 (mod 4). This bound can be lowered to 4 n + 2 in most cases.
Oxidative dehydrogenation (ODH) of ethane with O2 as oxidant on selected transition metal-loaded zeolites

Abstract Ni-, Cu-, and Fe-loaded acidic and basic Y zeolites were synthesized, and their catalytic properties for oxidative dehydrogenation of ethane (ODHE) to ethylene were characterized. Acidic Ni-loaded Y zeolite exhibits an ethylene productivity of up to 1.08 g C 2 H 4 g cat - 1 h - 1 with a selectivity of ∼75%. Acidic Cu- and Fe-loaded Y zeolites have an ethylene productivity of up to 0.37 g C 2 H 4 g cat - 1 h - 1 and a selectivity of ∼50%. For the same metal, the acidity of the zeolite favors both ODHE productivity and ethylene selectivity. Extended X-ray absorption fine structure (EXAFS) studies show that Ni, present in particles on Ni/HY during the ODHE catalytic process, contains both Ni–Ni and Ni–O bonds, and that the ratio of oxidized Ni versus metallic Ni increases with the temperature. The insights these studies provide into the ODHE reaction mechanism are discussed.
Misidentification of putative medullary thyroid cancer cell lines RO-H85-1 and RO-D81-1.

In 2008, the JCEM published a landmark paper showing redundancy or misidentification of almost 50% of a panel of 40 commonly used differentiated and anaplastic thyroid cancer cell lines (1); this finding had significant implications for the thyroid cancer research field (2). We have just found, by DNA fingerprinting (3), that two putative medullary thyroid cancer (MTC) cell lines appear to be misidentified. The cell lines are RO-H85-1 and RO-D81-1 (4). DNA fingerprinting was performed using the StemElite kit (Promega Corp, Madison, Wisconsin). A search of the ATCC (www.atcc.org) and DSMZ (www.dsmz.de) short tandem repeat (STR) databases revealed that RO-H85-1 appears to be closely related (82%) to the bladder cancer cell line 647-V, and RO-D81-1 appears to be highly related (100%) to the colon cancer cell line HT-29 (Table 1). For convenience, the STR genotypes of two commonly used MTC cell lines, TT and MZ-CRC-1, are included in Table 2. These cell lines have nonredundant genotypes, supporting their integrity as distinct cell lines. The genotype of the TT cell line is also available in the ATCC STR database. The initial report of the RO-H85-1 and RO-D81-1 cell lines (4) indicated that RO-H85-1 produced calcitonin, but RO-D81-1 did not. We received the RO-H85-1 and RO-D81-1 cell lines in 1990, and these stocks were frozen after 1 passage. Both 647-V (5) and HT-29 (6) were established prior to establishment of the RO-H85-1 (1985) and RO-D81-1 (1981) cell lines. We did not have either HT-29 or 647-V in our laboratory. Therefore, it appears likely that cross-contamination occurred before we received these cell lines. We share this information with the thyroid cancer research community to prevent potential futile research on MTC.
Crystal structures and magnetic properties of mixed iridium-ruthenium triple perovskites. 1. Ba3MRuIrO9 (M = lanthanide, Y)

Crystal structures and magnetic properties of Ba3MRuIrO9 (M = lanthanides, Y) were investigated. Rietveld refinements using powder diffraction data indicate that all the compounds crystallize in the 6H-BaTiO3 structure type in space group P63/mmc. Magnetic susceptibility measurements were carried out on each compound. Effective magnetic moments were smaller than values estimated using spin-only moments, which indicate the presence of spin−orbit coupling and strong interactions in the [(Ru0.5Ir0.5)2O9] face-sharing octahedra that contain a disordered mixture of Ru and Ir on a single crystallographic site. Magnetic anomalies were observed for the compounds Ba3PrRuIrO9, Ba3TbRuIrO9, and Ba3NdRuIrO9 at 3.5, 13, and 8 K, respectively.
Student Pharmacist Perspectives of Rural Pharmacy Practice

ABSTRACT Objective To evaluate the level of interest of upper-level doctor of pharmacy students in rural pharmacy practice, rural pharmacy ownership, and a proposed rural pharmacy practice model. Design Cross-sectional study. Setting Minnesota, North Dakota, and South Dakota in October through December 2003. Participants Third- and fourth-year professional student pharmacists at the University of Minnesota, North Dakota State University, and South Dakota State University. Intervention Self-administered questionnaire completed by study participants. Main Outcome Measures Student interest in rural pharmacy practice and potential future directions for maintaining access to medications and the knowledge of pharmacists in rural communities. Results Of 177 respondents, 62.7% has given serious consideration to practice in rural communities with populations of 5,000 or fewer residents. Of these 111 students, 81% would be interested in the proposed practice model explained in the survey. Of the 108 total students expressing interest in the proposed rural pharmacy practice model, 63% had not previously given serious consideration to pursuing ownership (full or partnership) of a community pharmacy. Conclusion Students from the schools that have traditionally supplied the majority of Minnesota rural pharmacists indicated an interest in practicing in rural areas as long as opportunities align with their personal and professional interests.
Clustering of unhealthy outdoor advertisements around child-serving institutions: A comparison of three cities

Using GPS devices and digital cameras, we surveyed outdoor advertisements in Austin, Los Angeles and Philadelphia. GIS and hot spot analysis revealed that unhealthy ads were clustered around child-serving institutions in Los Angeles and Philadelphia but not in Austin. Multivariate generalized least square (GLS) regression models showed that percent black (p<0.04) was a significant positive predictor of clustering in Philadelphia and percent white (p<0.06) was a marginally significant negative predictor of clustering in Los Angeles after controlling for several land use variables. The results emphasize the importance of zoning and land use regulations to protect children from exposure to unhealthy commercial messages, particularly in neighborhoods with significant racial/ethnic minority populations.
Relating information capacity to a biophysical model for blowfly photoreceptors

Abstract Photoreceptors measure and communicate information about visual stimuli to other neurons. In this process, the visual signal is converted between many different physical states. We present a communication channel model that describes transmission and degradation of the visual signal in the blowfly photoreceptor cell. The model is a cascade of linear systems and noise sources; these elements are derived from fundamental principles when possible, and parameters of the model are estimated from physiological data. We compute capacity and bit-energy using the model. Our results indicate that photon shot noise and channel noise are the dominant noise sources in blowfly phototransduction.
HOLY MEN AND BIG GUNS: The Can[n]on in Social Theory

Theory in sociology is constructed as a canon, a very short list of social theorists who have been endowed with suprahistorical status. Drawing on the feminist analysis of gendered consciousness, the author argues that social theory is organized exactly as it should be if one were thinking like a White male capitalist. The perceptual frameworks it employs—a hierarchy of the social, logical dichotomies, decontextualized abstraction, an individualist approach—resonate well with descriptions of hegemonic masculine consciousness. As a result, social theory has not just distorted social perception, it is becoming functionally irrelevant in contemporary social life. The author argues that reasonable understandings are more likely if we are developing via an epistemology of connection, moving from thinking of theory as a holy text to organizing theory to create bridges between diverse standpoints, across disciplinary boundaries, and between knowing and doing.
Data mining and genetic algorithm based gene/SNP selection

Objective: Genomic studies provide large volumes of data with the number of single nucleotide polymorphisms (SNPs) ranging into thousands. The analysis of SNPs permits determining relationships between genotypic and phenotypic information as well as the identification of SNPs related to a disease. The growing wealth of information and advances in biology call for the development of approaches for discovery of new knowledge. One such area is the identification of gene/SNP patterns impacting cure/drug development for various diseases. Methods: A new approach for predicting drug effectiveness is presented. The approach is based on data mining and genetic algorithms. A global search mechanism, weighted decision tree, decision-tree-based wrapper, a correlation-based heuristic, and the identification of intersecting feature sets are employed for selecting significant genes. Results: The feature selection approach has resulted in 85% reduction of number of features. The relative increase in cross-validation accuracy and specificity for the significant gene/SNP set was 10% and 3.2%, respectively. Conclusion: The feature selection approach was successfully applied to data sets for drug and placebo subjects. The number of features has been significantly reduced while the quality of knowledge was enhanced. The feature set intersection approach provided the most significant genes/SNPs. The results reported in the paper discuss associations among SNPs resulting in patient-specific treatment protocols.
Benchmarking effective educational practice

Factors Influencing Student Selection of Marriage and Family Therapy Graduate Programs.

To understand which factors students consider most important in choosing a marriage and family therapy (MFT) graduate program and how programs met or did not meet these expectations of students over the course of graduate study, we conducted an online mixed-method investigation. One hundred twelve graduate students in Commission on Accreditation for Marriage and Family Therapy Education-accredited programs responded to an online survey assessing what factors led them to select a specific graduate program in MFT. In the quantitative portion, students ranked each factor (personal fit, faculty, funding, research, clinical work, and teaching) as well as characteristics of each factor in relation to its importance in their selection of an MFT program. Additionally, students indicated to what level their programs meet their expectations. In the qualitative portion, students described how they believed their chosen program was or was not meeting their expectations. Both doctoral and master's students ranked personal fit as the top factor affecting their choice of graduate program in MFT, but they differed on the characteristics of each of these factors and their importance in selecting an MFT program. Implications for this research include program evaluation and program advertising, and are consistent with the scientist-practitioner model.
Vacuum-mixed silicate cements

The durability of silicate cements may be related to the porous nature of the spatulated mix. Vacuum mixing eliminates porosity, but the effect of the elimination of this porous nature on other properties of silicate cements has not been determined.
Luteinizing hormone, prolactin, and interval to ovulation after melengestrol acetate in cattle.

Abstract Nine Holstein heifers were fed 1 milligram melengestrol acetate daily for 18 days. After melengestrol acetate withdrawal, duration and magnitude of ovulatory surge of luteinizing hormone resembled that reported for control estrus, and serum prolactin was elevated the day before or on the day of luteinizing hormone surge. In another experiment 25 Holsteins lactating 60 to 90 days were fed 1 milligram melengestrol acetate daily for 14 days and injected with 2,500 international units of human chorionic gonadotropin on day 17. Based upon twice-a-day rectal palpations, 22 cows ovulated at an average of 36±3 hours after injection.
Detection, quantification, and significance of hiatuses in pelagic and hemipelagic strata

Temporal gaps in the stratigraphic record have important implications for the interpretation of stratigraphically rapid geochemical and paleobiologic changes, for the development of high-resolution time scales (e.g., orbital time scales), and for deciphering the response of depositional systems to climatic change and basin evolution (e.g., accommodation space vs. sediment supply). In ancient pelagic and hemipelagic strata, the identification of relatively short hiatus (10 3 –10 6 years) is commonly challenged by the resolution limits of geochronologic techniques. In this study, a quantitative method is developed to identify and quantify hiatuses in strata where Milankovitch orbital cycles are documented. The new method is based on the interpretation of evolutive harmonic analysis (EHA) results and permits estimation of minimum durations for the temporal gaps. Application of this technique to an optical densitometry data series derived from the Cenomanian/Turonian (C/T) Bridge Creek Limestone Member permits quantification of hiatus within the unit and addresses important questions about abrupt changes in biogeochemical proxy records across the boundary interval. Integration of the new method with stratigraphic data and geochemical burial flux estimates permits a detailed reconstruction of the controls on sediment delivery and hiatus generation, including a refined analysis of the orbital-scale linkages between climate and sedimentation.

Expanding the Role of Connectionism in SLA Theory

In this article, I explore how connectionism might expand its role in second language acquisition (SLA) theory by showing how some symbolic models of bilingual and second language lexical memory can be reduced to a biologically realistic (i.e., neurally plausible) connectionist model. This integration or hybridization of the two models follows the principles of what philosophers of science call intertheoretic reduction. Such a reduction serves two important purposes: It expands the explanatory scope of the symbolic models and it explains how some features of these models can actually emerge through learning in neural systems. To this end, I present a connectionist simulation of experimental data and show both the general feasibility of such a reduction and the specific manner in which the salient phenomenological distinction between form and meaning may be an emergent product of cortical memory processes. I argue this intertheoretic reduction of the symbolic to the neural serves an important goal of SLA, as these neural models can provide the theory of learning lacking in symbolic models of SLA.
Quality of Life in Thyroid Cancer is Similar to That of Other Cancers with Worse Survival

The incidence of thyroid cancer is increasing. As such, the number of survivors is rising, and it has been shown that their quality of life (QOL) is worse than expected. Using results from the North American Thyroid Cancer Survivorship Study (NATCSS), a large-scale survivorship study, we aim to compare the QOL of thyroid cancer survivors to the QOL of survivors of other types of cancer. The NATCSS assessed QOL overall and in four subcategories: physical, psychological, social, and spiritual well-being using the QOL-Cancer Survivor (QOL-CS) instrument. Studies that used the QOL-CS to evaluate survivors of other types of cancers were compared to the NATCSS findings using two-tailed t tests. We compared results from NATCSS to QOL survivorship studies in colon, glioma, breast, and gynecologic cancer. The mean overall QOL in NATCSS was 5.56 (on a scale of 0–10, where 10 is the best). Overall QOL of patients with thyroid cancer was similar to that of patients with colon cancer (mean 5.20, p = 0.13), glioma (mean 5.96, p = 0.23), and gynecologic cancer (mean 5.59, p = 0.43). It was worse than patients surveyed with breast cancer (mean 6.51, p < 0.01). We found the self-reported QOL of thyroid cancer survivors in our study population is overall similar to or worse than that of survivors of other types of cancer surveyed with the same instrument. This should heighten awareness of the significance of a thyroid cancer diagnosis and highlights the need for further research in how to improve care for this enlarging group of patients.
Dietary Conjugated Linoleic Acid Normalizes Impaired Glucose Tolerance in the Zucker Diabetic Fatty fa / fa Rat

Abstract Conjugated linoleic acid (CLA) is a naturally occurring fatty acid which has anti-carcinogenic and anti-atherogenic properties. CLA activates PPARα in liver, and shares functional similarities to ligands of PPARγ, the thiazolidinediones, which are potent insulin sensitizers. We provide the first evidence that CLA is able to normalize impaired glucose tolerance and improve hyperinsulinemia in the pre-diabetic ZDF rat. Additionally, dietary CLA increased steady state levels of aP2 mRNA in adipose tissue of fatty ZDF rats compared to controls, consistent with activation of PPARγ. The insulin sensitizing effects of CLA are due, at least in part, to activation of PPARγ since increasing levels of CLA induced a dose-dependent transactivation of PPARγ in CV-1 cells cotransfected with PPARγ and PPRE X 3-luciferase reporter construct. CLA effects on glucose tolerance and glucose homeostasis indicate that dietary CLA may prove to be an important therapy for the prevention and treatment of NIDDM.
Personal Health Management Systems: Applying The Full Power Of Software To Improve The Quality And Efficiency Of Care

Electronic medical records and personal health records have made good progress in reducing costs and inefficiencies, but the key to building a health care delivery system for the twenty-first century is to evolve toward personal health management systems that apply the full power of software to improve patient care. Such systems can enable better outcomes and improve the satisfaction of consumers and providers alike. Through technology innovation, sensible policy approaches, and industrywide collaboration, we can empower individuals to take control of their health while enabling providers and payers to broaden access to higher-quality, more affordable care.
Four-wavelength near-infrared imaging of abdominal aorta blood flow under surgical occlusion

This paper presents a four-wavelength near-infrared imaging system that can assist surgeons with intraoperative monitoring and imaging of blood flow of the vessel being occluded. The algorithm for this system, based on the Beer-Lambert law, calculates the relative concentrations of deoxyhemoglobin, oxyhemoglobin and water, which are the major NIR absorbers in tissues. Regional blood volume and oxygen saturation can be determined from these measurements. This proof-of-concept study investigated the utility of the algorithm on detecting rat infrarenal abdominal aortic blood flow subjected to various degrees of occlusion. The images provided a good visualization of the aorta because of the high concentration of oxyhemoglobin in the blood stream. The imager was able to detect when blood flow was completely stopped.

Reversible electrocochleographic abnormalities in superior canal dehiscence.

Objective:Electrocochleography (ECoG) is often used in the evaluation of episodic vertigo, and abnormal findings are commonly thought to be due to endolymphatic hydrops. We have observed that a number of patients with abnormal ECoG were ultimately found to have superior semicircular canal dehiscence

Hypertension prevalence and body mass index correlates among patients with diabetes mellitus in Oghara, Nigeria

Background: Hypertension and abnormal body mass index (BMI) are a cause of increased morbidity and mortality in patients with diabetes mellitus (DM). The aim of this study is to determine the prevalence of hypertension with correlates to BMI among patients with DM seen in a tertiary hospital in Oghara, Delta State. Materials and Methods: Two hundred and forty-four diabetic subjects were retrospectively evaluated at the Endocrinology Clinic of the Delta State University Teaching Hospital, Oghara, Nigeria. Data obtained from medical records included presence of hypertension confirmed by presence of elevated blood pressure >140/90 mmHg on two consecutive clinic visits or known hypertensive on medications, age, sex, type of diabetes, weight and height with computation of BMI. Results: The prevalence of hypertension among the diabetic patients was 57.4%. Eighty-two males (58.5%) were hypertensive compared with 58 (41.5%) in female subjects. The prevalence of hypertension was higher in overweight and obese diabetic subjects than in normal weight subjects and also higher in type 2 diabetic patients compared to type 1, which were both statistically significant (P < 0.05). Conclusion: Hypertension is a common co-morbidity arising diabetic patients in this study. The focus must be on health education, lifestyle modification and adherence to anti-hypertensive therapy to control hypertension in diabetic patients.
Comparison of Single Source Shortest Path Algorithms on Two Recent Asynchronous Many-task Runtime Systems

With the advent of the exascale era, new runtimes and algorithm design techniques need to be explored. In this paper, we investigate performance of three different single-source shortest path algorithms in two relatively recent asynchronous many-task runtime systems AMpp and HPX-5. We identify the underlying set of differential features for these runtimes, and we compare and contrast the performance of D-stepping algorithm, Distributed Control based algorithm, K-level Asynchronous algorithm in AMpp and in HPX-5, for which we also include chaotic implementation. We observe that specific runtime characteristics or lack thereoff and different graph inputs can impact the feasibility of an algorithmic approach.

Estimation and control of battery electrochemistry models: A tutorial

This paper presents a tutorial on estimation and control problems for battery electrochemistry models. We present a background on battery electrochemistry, along with a comprehensive electrochemical (EChem) model. EChem models present a remarkably rich set of control-theoretic questions involving model reduction, state & parameter estimation, and optimal control. We discuss fundamental systems and controls challenges, and then present opportunities for future research.
Making Vietnamese Music Transnational: Sounds of Home, Resistance and Change

In this essay I discuss how conditions in Viet Nam and abroad influenced the production, dissemination, and consumption of contemporary popular Vietnamese music. I trace the history of popular Vietnamese music since 1975 and highlight the voices of musicians, producers, and consumers in the U.S. and Viet Nam. Included in this analysis are three well-known music production companies—Paris By Night Thuy Nga Productions (PBN), Trung Tam Asia, and Kim Loi—and one network of independent Viet Kieu musicians, B-Flat. Taken together, the companies illustrate transnational culture flows and forms of collaboration between Vietnamese American and Vietnamese music makers.
A Traumatic Experience

Stage A 41-year-old woman collapsed at home and was taken to the hospital. In the emergency room, her blood pressure was 130/78 mm Hg, and her temperature was 36.5°C. No arrhythmia, murmur, or bruits were detected on cardiovascular examination. She was aphasic and had a left hemiparesis involving the face, arm, and leg. Response The case presented is of a young woman who was brought to the emergency room with a persistent neurologic deficit that is most consistent with stroke. I would like to know her history at this point, particularly whether she smoked or used medications, including oral contraceptives . . .

Homotopy Continuation for Correction Procedure via Reconstruction - Discontinuous Galerkin (CPR-DG) Methods

Homotopy continuation for correction procedure via reconstruction – discontinuous Galerkin (CPR-DG) methods is developed for solving steady state hyperbolic conservation laws. The efficacy of homotopy continuation has been demonstrated using both 1D and 2D steady flow problems. According to the test results, it is found that homotopy continuation can work robustly on flow simulations of shock capturing for a wide range of grid sizes and polynomial orders without parameter tuning.

Income Inequality: Impact of Inequality Measures on Crimes An Analysis of the State of New Jersey

This research used time-series data for the 50 year period of 1964 to 2014 to investigate the relationship between income inequalities and crimes in the state of New Jersey, United States of America. It found that income inequality had a significant relationship to all four types of crime measured – murder, forcible rape, aggravated assault and property crimes. Statistical significance would seem to depend on the model and inequality measure used. A log-log relationship existed between inequalities and all the crimes. Different inequality measures enabled different measures of significance. It also found that it was possible to come to different conclusions with respect to the relationships by using different inequality measures- the Gini and the 20/20 measures in our case.

Hereditary nephritis and pregnancy.

A 25-year-old woman is presented with congenital ocular defects, perceptive hearing loss since aged 8, and evidence of chronic renal disease since aged 19. During her second pregnancy she developed the nephrotic syndrome which spontaneously subsided post partum, despite persistent evidence of reduced renal function and proteinuria. A percutaneous renal biopsy revealed the changes associated with hereditary nephritis with deafness. It is postulated that the increase in renal blood flow and glomerular filtration rate, which usually accompanies pregnancy, increased the urinary excretion of protein until serum albumin was reduced and the clinical pattern of the nephrotic syndrome emerged.
Photodynamic Therapy for the Management of Laryngeal Malignancies

Carcinoma of the larynx accounts for 25–30 % of all carcinomas of the head and neck [1]. Early carcinomas of the larynx (Cis, T1, T2) and severe dysplasia are presently treated with either radiation therapy or surgery alone. Five-year cure rates achieved with this therapy is 75–90 %. Radiation therapy has the advantage of preserving the physical integrity of the larynx, thereby preserving the voice. Radiation therapy, however, has significant disadvantages even when small laryngeal fields of radiation are used. These disadvantages include discomfort and mucositis during and for potential prolonged periods after therapy, permanently altered voice quality, dysphagia, chondroradionecrosis of the larynx and trachea, and the extensive length of therapy (6–7 weeks) [2, 3]. Surgical therapy for early carcinomas, that is, T1 and T2, of the larynx includes performing a partial cordectomy or hemilaryngectomy. Although cure rates are high, surgical removal of portions of the vocal cord or hemilarynx results in significant alteration of the quality of voice [4].
