"Turn Left after the WC, and Use the Lift to Go to the 2nd Floor" - Generation of Landmark-Based Route Instructions for Indoor Navigation

People in unfamiliar environments often need navigation guidance to reach a destination. Research has found that compared to outdoors, people tend to lose orientation much more easily within complex buildings, such as university buildings and hospitals. This paper proposes a category-based method to generate landmark-based route instructions to support people’s wayfinding activities in unfamiliar indoor environments. Compared to other methods relying on detailed instance-level data about the visual, semantic, and structural characteristics of individual spatial objects, the proposed method relies on commonly available data about categories of spatial objects, which exist in most indoor spatial databases. With this, instructions like “Turn right after the second door, and use the elevator to go to the second floor” can be generated for indoor navigation. A case study with a university campus shows that the method is feasible in generating landmark-based route instructions for indoor navigation. More importantly, compared to metric-based instructions (i.e., the benchmark for indoor navigation), the generated landmark-based instructions can help users to unambiguously identify the correct decision point where a change of direction is needed, as well as offer information for the users to confirm that they are on the right way to the destination.
MOv18 Monoclonal Antibody in Diagnostic Applications: Capability to Recognize the Histotype of the Original Tumor

Cells from 52 ascitic fluids and 28 abdominopelvic cavity washings, obtained from 46 ovarian cancer patients, 17 patients bearing malignancies of non ovarian sites and 17 patients with non-malignant ovarian diseases, were tested using 2 methods: traditional cytology and monoclonal antibody immunofluorescence. The immunologic test using the MOv18 MAb, raised against ovarian carcinoma, revealed immunoreactive cells in 83 % of the 36 cytologically positive fluids and in one of the 8 negative fluids from ovarian carcinoma patients and in 18% of the 17 fluids from patients with non-malignant ovarian disease. Forty six cytologically positive ascitic fluids from malignant patients were analyzed in order to evaluate the ability of this MAb to identify the histotype of metastatic cells. Ninety-three percent (26/28) of the effusions from non-mucinous ovarian carcinomas contained MOv18-positive cells, whereas no reactive cells were found in cytologically malignant fluids from patients with ovarian tumors of other oncotypes or with carcinomas of non-ovarian origin. The MOv18 reagent, used as an adjuvant in cytological analysis, can help in the identification of the histotype of metastatic cells of unknown origin.
Closing the Gap: An Empirical Evidence on Firm's Innovation, Productivity, and Export

It is well known that exporters are productive firms. But the source of their productivity is left unexplained. This paper aims to endogenize the productivity heterogeneity of exporting firms by incorporating innovation in a structural model framework. In doing so, we close the gap between the innovation-productivity and productivity-export literature. Two waves of Swedish Community Innovation Survey (CIS) are merged. This allows for a dynamic setup that takes into account the proper lags from innovation input to innovation output and also from innovation output to productivity and export. The applied framework corrects for selectivity, simultaneity, and potential endogeneity biases. The main findings highlight that exporters are productive firms with innovation output in the past, which in turn was driven by prior R&D and other innovation activity investments.
Use the supply relationship to develop lean and green suppliers

Three main concepts (supply relationship, lean manufacturing, and environmental management practices) and their relationship to one another are described and the discussion concludes with major hypotheses for further research in this area.Findings – A major literature review reveals that efforts to improve or influence a supplier's environmental management practice raises critical issues of transaction costs and efficacy of approach for the buyer. The review allowed development of a model for approaching issues of supplier environmental performance through lean supply.Originality/value – The environmental performance of suppliers to the supply function can prove to be a costly endea.
Relational contract norms and the effectiveness of commercial banking relationships

Bases the present study, on Macneil’s relational contract theory and illustrates the conceptual and managerial importance of relational norms in a business‐to‐business service context. Demonstrates a clear link between the client’s perception of the strength of the bank‐client relationship, as measured by relational norms, and the client’s intention to continue to purchase financial services and to purchase new financial services, willingness to recommend both the account manager and the bank to business colleagues and, assessment of satisfaction and judgement of service quality. Finds significant differences between the assessment of the strength of the relationship by account managers and client‐company representatives; these differences would have important managerial implications in the context of commercial banking.
STUDIES ON THE OXIDATION OF 1,4-DISUBSTITUTED-1,2,3,6-TETRAHYDROPYRIDINES

Interest in the parkinsonian-inducing proneurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine has prompted extensive studies into the oxidative pathways mediating its bioactivation to the corresponding pyridinium species, a potent inhibitor of the mitochondrial electron transport chain. The initial step in the overall reaction is the two-electron ring α-carbon oxidation to give the 1-methyl-4-phenyl-2,3-dihydropyridinium species, a reaction that is catalyzed by monoamine oxidase B. The same α-carbon oxidation is catalyzed by members of the cytochrome P-450 family of oxidases. This paper examines the impact that various structural features of 1,4-disubstituted-1,2,3,6-tetrahydropyridinyl derivatives have on the oxidative fate of this class of compound.
Carotid intima-media thickness is a novel predictor of new onset of hypertension in normotensive subjects

Abstract Increased carotid intima-media thickness (IMT) in individuals without hypertension might indicate other factors promoting the atherosclerotic process that are often simultaneously clustered in individuals. The present study tested the hypothesis that carotid IMT predicts new onset of hypertension in the normotensive subjects. A total of 867 participants were enrolled from our yearly physical checkup program and their carotid IMT was measured. After a baseline examination, the subjects were followed up for a median of 1091 days with the endpoint being the development of hypertension. At baseline, the carotid IMT value was 0.75 ± 0.16 mm. Hypertension developed in 184 subjects during the follow-up (76.9/1000 person-years). The incidence of hypertension was increased across the tertiles of the carotid IMT value (39.6, 70.0, and 134.5/1000 person-years in the first, second, and third tertiles, respectively, P < .001 by log-rank test). Multivariate Cox-hazard analysis after adjustment identified carotid IMT, taken as a continuous variable, as a significant predictor of new-onset hypertension (hazard ratio = 7.08, 95% confidence interval = 3.06–15.39). Furthermore, multivariate linear regression analyses indicated a significant correlation between the carotid IMT at baseline and yearly increases in systolic blood pressure during the follow-up period (&bgr; = 0.189, P < .001). Carotid IMT is an independent predictor of hypertension onset in normotensive subjects. The findings also suggested a close association between increased carotid IMT and blood pressure.
Are beta, firm size, liquidity and idiosyncratic volatility related to stock returns? Australian evidence

The paper is aimed at examining the inter-relationships between firm size, liquidity, idiosyncratic volatility and their relation to a stock's beta and return performance for Australian equities. Our analysis suggests the existence of confounding effects that may need to be recognised in making meaningful interpretations of the data; specifically, that as well as being potentially explanatory of equity performance, beta, liquidity and idiosyncratic volatility are capable of being the outcome of equity performance behaviour. Over and above achieving a degree of clarification on these issues, the paper's main conclusions are summarised as follows. We find no relationship between beta, firm size, liquidity or idiosyncratic volatility and stock returns for large stocks. However, the smallest capitalised stocks markedly outperform the largest capitalised stocks, and for such small capitalised stocks those with greater idiosyncratic volatility have markedly superior returns.
Pulse transit time differential measurement by fiber Bragg grating pulse recorder

Abstract. The present study reports a noninvasive technique for the measurement of the pulse transit time differential (PTTD) from the pulse pressure waveforms obtained at the carotid artery and radial artery using fiber Bragg grating pulse recorders (FBGPR). PTTD is defined as the time difference between the arrivals of a pulse pressure waveform at the carotid and radial arterial sites. The PTTD is investigated as an indicator of variation in the systolic blood pressure. The results are validated against blood pressure variation obtained from a Mindray Patient Monitor. Furthermore, the pulse wave velocity computed from the obtained PTTD is compared with the pulse wave velocity obtained from the color Doppler ultrasound system and is found to be in good agreement. The major advantage of the PTTD measurement via FBGPRs is that the data acquisition system employed can simultaneously acquire pulse pressure waveforms from both FBGPRs placed at carotid and radial arterial sites with a single time scale, which eliminates time synchronization complexity.
MV cable termination failure assessment in the context of increased use of power electronics

In this work, the performance of cable termination used in the context of increased use of power electronics is studied. The experimental work analyses the cable termination degradation process when exposed to steep front non-sinusoidal voltage waveforms. The Partial Discharge (PD) measurements are carried out before and after the accelerated aging experiment to study the insulation degradation under high frequency medium voltage stress. Results obtained from the surface temperature measurements using infra red camera are also used in the analyses.
New resource allocation scheme for cognitive relay networks with opportunistic access

In this paper, a new resource allocation scheme to minimize Symbol Error rate (SER) for relay assisted cognitive radio networks is studied. A cognitive relay network with amplify-and-forward (AF) fixed gain relays and opportunistic access to the licensed spectrum is considered. The SER objective function and the optimization constraints are derived first. The resource allocation algorithm is then derived using the Langrangian multiplier method. Closed form expressions are derived for the source and relay powers and, symbol time. Analytical results show that the optimal power allocation follows an extended water-filling solution.
Comparative Anatomy of Marmoset and Mouse Cortex from Genomic Expression

Advances in mouse neural circuit genetics, brain atlases, and behavioral assays provide a powerful system for modeling the genetic basis of cognition and psychiatric disease. However, a critical limitation of this approach is how to achieve concordance of mouse neurobiology with the ultimate goal of understanding the human brain. Previously, the common marmoset has shown promise as a genetic model system toward the linking of mouse and human studies. However, the advent of marmoset transgenic approaches will require an understanding of developmental principles in marmoset compared to mouse. In this study, we used gene expression analysis in marmoset brain to pose a series of fundamental questions on cortical development and evolution for direct comparison to existing mouse brain atlas expression data. Most genes showed reliable conservation of expression between marmoset and mouse. However, certain markers had strikingly divergent expression patterns. The lateral geniculate nucleus and pulvinar in the thalamus showed diversification of genetic organization between marmoset and mouse, suggesting they share some similarity. In contrast, gene expression patterns in early visual cortical areas showed marmoset-specific expression. In prefrontal cortex, some markers labeled architectonic areas and layers distinct between mouse and marmoset. Core hippocampus was conserved, while afferent areas showed divergence. Together, these results indicate that existing cortical areas are genetically conserved between marmoset and mouse, while differences in areal parcellation, afferent diversification, and layer complexity are associated with specific genes. Collectively, we propose that gene expression patterns in marmoset brain reveal important clues to the principles underlying the molecular evolution of cortical and cognitive expansion.
New Method to Separate Failure Modes by Transient Thermal Analysis of High Power LEDs

A high reliability of light emitting diode (LED) light sources is essential for general and automotive lighting applications, where exchange of LED components is expensive. Thermal management of modern high power LEDs is crucial for their lifetime. An important aspect is the thermal path for heat conduction. Many different defects can have an influence on this path of an electronic system: on the one hand process failures during production, e.g. voids inside the solder joint, on the other hand typical failures induced by thermo-mechanical stress during their lifetime, like cracks in the solder joint or delamination in the package. The transient thermal analysis (TTA) is a powerful tool to detect changes in the thermal path. Due to improvements in the TTA method during the last years, not only cracks can be detected but also failure modes can be separated, and the root cause can be analyzed by support of transient finite element analysis. In this paper, transient thermal testing is applied and further developed, to monitor the structural integrity of new wafer level LED packages during thermal stress testing. Failure modes are defined and separated. For failure analysis the different defects are simulated by transient finite element analysis and correlated to the TTA results. The simulation results, that solder cracks increase the peak height of the derivative of the transient thermal curves (b(z)). A delamination of an inner layer of the LED package creates additionally to the increase of the peak height also a separation of the b(z) curves between 1 µs and 5 µs. Therefore a transient thermal measurement equipment with a dead time
Trends in inpatient continuity of care for a cohort of Medicare patients 1996-2006.

BACKGROUND Little is known about how changes in health care delivery, such as the use of hospitalists, have impacted inpatient continuity. OBJECTIVE To examine the extent of inpatient discontinuity (ie, being seen by more than one generalist physician) during hospitalization for selected patients. DESIGN Retrospective cohort. SETTING 4,859 US hospitals. PATIENTS Medicare fee-for-service beneficiaries hospitalized for chronic obstructive pulmonary disease (COPD), pneumonia, and congestive heart failure (CHF) from 1996 through 2006. MEASUREMENTS We analyzed the proportion of Medicare beneficiaries who received care from 1, 2, or 3 or more generalist physicians during hospitalization. We also examined the factors associated with continuity during the hospitalization. RESULTS Between 1996 and 2006, 64.3% of patients received care from 1, 26.9% from 2 and 8.8% from 3 or more generalist physicians during hospitalization. The percentage of patients who received care from one generalist physician declined from 70.7% in 1996 to 59.4% in 2006 (P < 0.001). In a multivariable analysis, continuity with one generalist physician decreased by 5.5% (95% CI, 5.3%-5.6%) per year between 1996 and 2006. Patients receiving all care from hospitalists saw fewer generalist physicians compared to those who received all care from a non-hospitalist or both. Older patients, females, non-Hispanic whites, those with higher socioeconomic status, and those with more comorbidities were more likely to receive care from multiple generalist physicians. LIMITATIONS The results may not be generalizable to non-Medicare populations. CONCLUSIONS Hospitalized patients are experiencing less continuity than 10 years ago. The hospitalist model of care does not appear to play a role in this discontinuity.
Subtraction-free complexity and cluster transformations

Subtraction-free computational complexity is the version of arithmetic curcuit complexity that allows only three arithmetic operations: addition, multiplication, and division. We use cluster transformations to design efficient subtraction-free algorithms for computing Schur functions and their skew, double, and supersymmetric analogues. We also describe such algorithms for generating functions of spanning trees.
Brosimum Alicastrum as a Novel Starch Source for Bioethanol Production

Ramon (Brosimum alicastrum) is a forest tree native to the Mesoamerican region and the Caribbean. The flour obtained from Ramon seeds is 75% carbohydrate, of which 63% is starch, indicating its potential as a novel raw material for bioethanol production. The objective of this study was to produce ethanol from Ramon flour using a 90 °C thermic treatment for 30 min and a native yeast strain (Candida tropicalis) for the fermentation process. In addition, the structure of the flour and the effects of pretreatment were observed via scanning electron microscopy. The native yeast strain was superior to the commercial strain, fermenting 98.8% of the reducing sugar (RS) at 48 h and generating 31% more ethanol than commercial yeast. One ton of flour yielded 213 L of ethanol. These results suggest that Ramon flour is an excellent candidate for ethanol production. This is the first report on bioethanol production using the starch from Ramon seed flour and a native yeast strain isolated from this feedstock. This alternative material for bioethanol production minimizes the competition between food and energy production, a priority for Mexico that has led to significant changes in public policies to enhance the development of renewable energies.
Work engagement as a reaction to work environment and customer outcome: a service marketing perspective

The concept of work engagement and its impact on marketing performance continues to draw the attention of research scholars and business professionals in developed countries. As less research work has been carried out in this area in Asia, this study reports several job resources, such as employee autonomy, employee advancement, employee role clarity, and organizational support as triggering factors of employee work engagement in Indian service setting. Additionally, using path analysis, the study establishes not only direct but also significant indirect relationships between various job resources and customer satisfaction. These indirect relationships are well connected by several dimensions of work engagement as intermediating variables, thus further highlighting the relevance of work engagement for service marketing practitioners.
2D unitary ESPRIT for efficient 2D parameter estimation

Considers multiple narrowband signals that are incident upon a planar sensor array. 2D unitary ESPRIT is a new closed-form high resolution algorithm to provide automatically paired source azimuth and elevation angle estimates along with an efficient way to reconstruct the impinging signals. In the final stage of the algorithm, the real and imaginary parts of the ith eigenvalue of a matrix are one-to-one related to the respective direction cosines of the ith source relative to the two array axes. 2D unitary ESPRIT offers several advantages over other ESPRIT based closed-form 2D angle estimation techniques. First, except for the final eigenvalue decomposition of dimension equal to the number of sources, it is efficiently formulated in terms of real-valued computation throughout. Second, it is amenable to an efficient DFT beamspace implementation. Third, it is also applicable to array configurations that do not exhibit three identical subarrays, as long as the array is centro-symmetric and possesses invariances in two distinct directions. Finally, 2D unitary ESPRIT easily handles sources having one member of the spatial frequency coordinate pair in common.
Leu 7 Pro polymorphism of preproneuropeptide Y during a course of metabolic disease : functional analysis by gene ontology

Background and Purpose: Neuropeptide Y (NPY), one of the most abundant neuropeptides found in the central nervous system (CNS), has been implicated in the regulation of many metabolism. Preproneuropeptide Y (PPNPY) is the signal peptide of the NPY. Effect of PPNPY Leu7Pro polymorphism on metabolic disorder is widely discussed and still controversial. Material and Methods: To study the functional aberration in the human wild and mutate types of PPNPY in pathogenesis of type 2 diabetes is hard. Here, the author used a new gene ontology technology to predict the molecular function of human wild and mutate types of PPNPY. Results: Here, it can be seen that there is no functional difference between wild and mutate types of PPNPY. The common functions as Receptor binding, G-protein coupled receptor binding, hormone activity, neuropeptide hormone activity, G-protein coupled receptor activity, calcium channel regulator activity can be seen. Conclusion: This can support the null effect of this polymorphism in clinical findings of the patients. Therefore, this polymorphism might not be an important factor and have null effect in metabolic disorder. Finally, the author hereby recommends for a further study to analyze other know genetic variants within PPNPY gene to add more knowledge.
Treatment of relapsed undifferentiated acute myeloid leukemia (AML-M0) with Ayurvedic therapy

A 16-year-old boy was detected with acute myeloid leukemia (AML – M0) with bone marrow pathology showing 85% blasts in February 07, 1997. He received two cycles of induction chemotherapy (3+7 protocol) with daunomycin and cytosar, following which he achieved incomplete remission with bone marrow aspirate showing 14% blasts. Subsequently, the patient received two cycles of high-dose cytosine arabinoside Ara-C and achieved remission. However, his disease relapsed on August 29, 1997. Peripheral blood smear showed 6% blast cells and bone marrow showed 40% blast cells. The patient refused further chemotherapy and/or bone marrow transplant and volunteered for Ayurvedic therapy (AYT) advocated by the author from September 09, 1997. Bone marrow studies done after six months of AYT indicated that the disease was in remission. The AYT was continued for five years and stopped. Thereafter, the patient received intermittent maintenance AYT for three months in the next two years. At present, the patient is normal and healthy and has completed 12 years of disease-free survival with AYT.
