A Scheme on Indoor Tracking of Ship Dynamic Positioning Based on Distributed Multi-Sensor Data Fusion

Investigating the model ship dynamic positioning system by simulating the actual sea conditions in the laboratory can not only avoid the risks caused by the directly experiments on a true ship, but also reduce the costs. With the purpose of realizing the high accuracy control of the dynamic positioning, besides a high accuracy mathematical model of the ship, an important condition is that the position information provided by the position detection system must be accurate, reliable, and continuous. The global positioning system (GPS) signal is restricted when the model ship dynamic positioning system is set indoors. This paper describes a novel scheme for ship target tracking based on the multi-sensor data fusion techniques. To improve the accuracy of indoor positioning and ship target tracking, the characteristics of many sensors are systematically analyzed, such as radar, difference GPS, and ultrasonic sensors. Other important factors, including the indoor temperature, position, and environment, are also taken into account to further optimize the performance. Combining the Kalman filter method, the time alignment method, the coordinate transformation method, and the optimal fusion criterion method, the core algorithm of our framework employs the track correlation as the performance index of the optimal fusion. The experimental results indicate that our method outperforms the methods based on a single ultrasonic sensor. The maximum error between the estimated location and the real location is only 1.32 cm, which meets the standard for engineering applications.
11q Deletions in Hematological Malignancies

Structural aberrations involving 11q are among the most common aberrations in a number of hematological malignancies. Most of the aberrations, such as translocations and deletions, often harbor a breakpoint at 11q23, which suggests that this region might contain a tumor suppressor gene important for the genesis of lymphoproliferative disorders. Interestingly, deletions are concentrated only in some subtypes of hematological malignancies, where they are detected at a relatively high frequency. In B-cell chronic lymphocytic leukemia (B-CLL), deletions have been detected in 20–30% of the cases, whereas almost half of the mantle cell lymphomas (MCL) show deletion at 11q23 in fluorescence in situ hybridization analysis. In T-cell prolymphocytic leukemia (T-PLL), deletions involving the region 11q23.3–23.1 have also been detected to be frequent. In B-cell chronic lymphocytic leukemia, 11q deletion is associated with more rapid disease progression and poor survival in a younger subgroup of patients. The putative tumor suppressor genes have remained unrevealed until recently, when the ATM gene was found to carry mutations in cases with deletion in B-CLL, MCL and T-PLL. These data suggest that 11q deletions and dysfunction of the ATM gene might have significance in the tumorigenesis of certain subsets of hematological malignancies. Importance of 11q deletion as a diagnostic marker needs to be further studied in a larger series of patients. Another issue that remains to be investigated is the involvement of other target genes in the deletion.
Walther Spielmeyer and Japanese Neuropathology

In 1912 Emil Kraepelin, ohe of the founding fathers of psychiatry as a medical science and the great taxonomist of his discipline, appointed Walther Spielmeyer to his clinical department at the University of Munich. He thus became the chief of the anatomical laboratory abandoned by Alois Alzheimer, who had left Munich for a position as Full Professor of Psychiatry at the University of Breslau. In 1917 the “Deutsche Forschungsanstalt fur Psychiatrie” was founded which is now the Max-Planck-Institute for Psychiatry in Munich and Martinsried. Three morphological units were established under Franz Nissl, Korbinian Brodmann and Walther Spielmeyer. Spielmeyer‘s international reputation was based on his mastery of the methods of neurohistology, which he used to establish the hktopathology of the nervous system as a systematic discipline, very much in contrast to the prevailing anectodal phenomenology. Since most of the first generation of neuropathologists were clinicians, their major interest was to explain clinical symptoms by localising anatomical lesions. The systematic study of the cellular processes underlying brain diseases was a novel approach which only became possible by applying reliable staining methods such as Nissl‘s basic aniline dye technique or Spielmeyer‘s own myelin stain. With a solid background in these techniques Spielmeyer had made a number of remarkable discoveries. He first described the juvenile form of amaurotic idiocy and recognized it as a storage disease of neurons. His contributions to the study of cerebrovascular diseases, peripheral nerve injury, and of toxic and inflammatory processes were seminal. He recognized the very important role of the glial cells in the general pathology of the brain. Today, at a time where immunological and
Regulation of Cell Death and Innate Immunity by Two Receptor-like Kinases in Arabidopsis

SUMMARY Upon recognition of bacterial flagellin, the plant receptor FLS2 heterodimerizes with brassinosteroid insensitive 1-associated receptor kinase 1 (BAK1) and activates plant defense responses. Because constitutive activation of defense responses is detrimental , plant resistance signaling pathways must be negatively controlled, although the mechanisms involved are unclear. We identified Arabidopsis BIR1 as a BAK1-interacting receptor-like kinase. Knocking out BIR1 leads to extensive cell death, activation of constitutive defense responses, and impairment in the activation of MPK4, a negative regulator of plant resistance (R) protein signaling, by flagellin. sobir1-1, a mutant obtained in a screen for suppressors of the bir1-1 phenotype, rescued cell death observed in bir1-1. SOBIR1 encodes another receptor-like kinase whose overexpression activates cell death and defense responses. Our data suggest that BIR1 negatively regulates multiple plant resistance signaling pathways, one of which is the SOBIR1-dependent pathway identified here.
Topographically guided laser in situ keratomileusis for myopia using a customized aspherical treatment zone

Pseudoexfoliation (PFX) is characterized by the abnormàl production and accumulation of a fibrillar extracellular material with a gray appearance in the anterior segment of the eye and other tissues of the body. It is the most common identifiable cause of open-angle glaucoma, and there is an etio1oical association between PFX and cataract formation. Complication rates for cataract surgery in eyes with PFX are higher than in eyes without PFX. Because of the association of PFX with glaucoma and cataract, there is a need to assess the effect of cataract surgery on intraocular pressure (lOP) in such eyes. Several small series of PFX eyes having phacoemulsification show a small, but significant decrease in lOP after relatively short follow-up. The purpose of this study was to assess the short-term and long-term effects of uneventful phacoemulsification with posterior chamber intraocular lens (PC IOL) implantation for visually significant cataract in a large series of PFX eyes with and without glaucoma using the following parameters: best corrected visual acuity (BCVA), IOP, and glaucoma medication requirements.
Knowledge and Practices of Toxoplasmosis among Clinical Laboratory Professionals: A Cross-Sectional Study in Durango, Mexico

Background: The aim of this study was to determine the level of knowledge and practices about toxoplasmosis in a sample of clinical laboratory professionals in Mexico. Methods: 192 clinical laboratory professionals were surveyed. They were asked about (1) Toxoplasma gondii; (2) clinical manifestations, diagnosis, treatment, and epidemiology of toxoplasmosis; and (3) their practices with respect to toxoplasmosis. Results: The range of animals infected by T. gondii was known by 44.8% of participants. Clinical aspects of toxoplasmosis were known by up to 44.3% of subjects. Correct answers about the interpretation of serological markers of T. gondii infection were provided by up to 32.8% of participants. A minority (32.2%) of participants knew about a high number of false positive results of anti-T. gondii IgM antibody tests. Most participants (90.1%) did not know what the anti-T. gondii IgG avidity test was. Up to 55.7% of participants provided incorrect answers about the interpretation of serology tests for the treatment of pregnant women. Common routes of T. gondii infection were known by <15% of participants. Most (84.4%) participants had not performed tests for detection T. gondii infection. Conclusions: Results indicate incomplete knowledge of T. gondii infection and toxoplasmosis and a limited practice of laboratory tests among the professionals surveyed.

The Past , Present , and Future of HIV Prevention : Integrating Behavioral , Biomedical , and Structural Intervention Strategies for the Next Generation of HIV Prevention

In the past 25 years, the field of HIV prevention research has been transformed repeatedly. Today, effective HIV prevention requires a combination of behavioral, biomedical, and structural intervention strategies. Risk of transmitting or acquiring HIV is reduced by consistent maleand female-condom use, reductions in concurrent and/or sequential sexual and needle-sharing partners, male circumcision, and treatment with antiretroviral medications. At least 144 behavioral prevention programs have been found effective in reducing HIV transmission acts; however, scale up of these programs has not occurred outside of the United States. A series of recent failures of HIV-prevention efficacy trials for biomedical innovations such as HIV vaccines, treating herpes simplex 2 and other sexually transmitted infections, and diaphragm and microbicide barriers highlights the need for behavioral strategies to accompany biomedical strategies. This challenges prevention researchers to reconceptualize how cost-effective, useful, realistic, and sustainable prevention programs will be designed, delivered, tested, and diffused. The next generation of HIV prevention science must draw from the successes of existing evidence-based interventions and the expertise of the market sector to integrate preventive innovations and behaviors into everyday routines. 143 A nn u.

On the structure of extremal graphs of high girth

Let n ≥ 3 be a positive integer, and let G be a simple graph of order v containing no cycles of length smaller than n + 1 and having the greatest possible number of edges (an extremal graph). Does G contain an n + 1–cycle? In this paper we establish some properties of extremal graphs and present several results where this question is answered affirmatively. For example, this is always the case for (i) v ≥ 8 and n = 5, or (ii) when v is large compared to n: v ≥ 2a2+a+1na, where a = n − 3 − n−2 4 , n ≥ 12. On the other hand we prove that the answer to the question is negative for v = 2n + 2 ≥ 26. ∗This paper appeared in J.

Atherosclerosis burden and coronary artery lesion complexity in acute coronary syndrome patients.

BACKGROUND Syntax score (SS) is a prognostic marker in patients with acute coronary sydromes (ACS). Carotid intima media thickness (CIMT) and cardio ankle vascular index (CAVI) are well known surrogate marker of atherosclerosis burden. But association between atherosclerosis burden and coronary artery disease (CAD) complexity in ACS patients has not been investigated yet. METHODS AND RESULTS Consecutive patients with first time diagnosis of ACS (n = 172) were enrolled. SS, a marker of CAD complexity, was assessed by dedicated computer software. CIMT was examined by B-mode ultrasound. CAVI was assessed by VaSera VS-1000 cavi instrument. SS for low, intermediate and high tertiles of CIMT value were 10.1 ± 8.2 vs 11.4 ± ± 7.9 and 15.2 ± 8.8; p = 0.02). SS for normal, borderline and abnormal CAVI values were 4 ± 3.7 vs 11.1 ± 7.2 and 14.1 ± 9.1, respectively p = 0.009). Also, there was independent association between SS and CIMT (95% coinfidence interval [CI] 2.1-19, p = 0.014) and CAVI (95% CI 15-29, p = 0.021]. Neither traditional cardiovascular risk factor nor thrombolysis in myocardial infarction (TIMI) risk score was independent determinant of SS. CONCLUSIONS We have shown that patients with higher atherosclerosis burden have more complex coronary artery lesions. Also these patients may be identified early by using surrogate markers of atherosclerosis. Its clinical significance requires further research.
Delay-efficient GOP size control algorithm in Wyner-Ziv Video Coding

In Wyner-Ziv Video Coding (WZVC) (a special form of distributed video coding) the heavy work of motion estimation is shifted to the decoder. Unlike conventional video systems, such a scheme allowed for new emerging technologies that require low-complexity encoders. A key factor to the performance of WZVC is the quality of the Side Information (SI) present at the decoder which heavily depends on the key frame separation. For this reason, the Group Of Pictures (GOP) size plays a significant role in the coding efficiency of the system. In this paper, we focus on the control of GOP size in transform-domain WZVC with feedback channel. We present a novel algorithm that performs online selection of the GOP size relying on past system behavior. Our proposed algorithm incurs minimal delays to the system making it suitable for real-time applications.
Choosing Hispanic Identity: Ethnic Identity Switching among Respondents to High School and Beyond.

Assimilation and enclosure models of ethnicity developed for European-American populations predict that ethnic identity is maintained in contexts of structural and cultural isolation, but becomes fluid and optional outside of those contexts. The research tests the applicability of these models to the Hispanic-origin population. The authors analyze data for respondents who self-identified with a Hispanic origin in response to the first survey administered to the High School and Beyond (HS&B) panel. They estimate a logistic regression model to identify correlates of reporting non-Hispanic identity in response to the second-wave survey, administered two years later. English monolingualism and attendance at a school with few Hispanic students are strongly associated with inconsistent reporting of Hispanic identity. Increasing socioeconomic status has a weaker effect. Inconsistent Hispanic identification is less common in urban areas and in census divisions with large Hispanic populations. Assimilation and enclosure models do apply to the sampled population. Hispanic identity becomes inconsistent for Hispanic-origin teenagers who do not speak Spanish. Growth of Hispanic-origin populations may counteract this effect in the future
Cross-Cultural Analysis in Evolution and Human Behavior Studies

This special issue of Cross-Cultural Research is dedicated to evolutionary approaches. Each article was solicited individually; however, they form an unexpectedly cohesive corpus. Carol and Melvin Ember and Nigel Barber examine similar strains of life history theory relevant to socialization for warfare and crime. Rob and Marsha Quinlan and Frank Marlowe explore male–female complementarity in pair-bonds and the division of subsistence labor. Brad Huber and William Breedlove examine the effects of paternal certainty and kinship laterality in perinatal care. Most of the contributions here are holocultural studies by anthropologists; however, Nigel Barber’s crossnational study shows that an evolutionary comparative perspective can benefit social psychology too. Cross-cultural analysis can be particularly useful in studies of human evolution. The approach allows exploration of the current adaptive function of a trait and the selective pressures that may have provided the initial “evolutionary kick. ” Research in human evolutionary or behavioral ecology has been dominated by case studies of intracultural variation. Often the questions are best addressed at that level; however, contradictory findings from two or more case studies can lead us down a blind alley. Theory tested and built solely on case studies can lead to unnecessary polemics. Evolutionary anthropologists (and some evolutionary psychologists) agree that humans are adapted for ecological contingencies. Yet we often hear arguments about the single selective pressure or function of some dimension of human behavior. Those arguments could result from the different factors field-workers observed in their specific case study. A cross-cultural approach allows us to examine factors associated with a specific trait or behavior across a range of social environments. Similarly, the debate among evolutionary psychologists and anthropologists concerning ecological variation in evolved Cross-Cultural Research Volume 41 Number 2 May 2007 91-95 © 2007 Sage Publications 10.1177/1069397106298894 http://ccr.sagepub. com hosted at http://online.sagepub. com
A simulated driving evaluation for patients with Alzheimer's disease

A prospective study concerning the driving ability of 41 patients with the diagnosis of Alzheimer's disease (AD) was performed. Using a simulated driving test we evaluated the predictive value of the MMSE,'4 ADL,5-7 and IADL&9 to determine the ability of a person with Alzheimer's disease to drive. All patients were driving at the time of the evaluation. There was no correlation between driving performance and functional status evaluated by ADL and IADL. When comparing driving performance with cognitive evaluation by MMSE, a significant number of patients with MMSE c 22failed the test, compared to patients with MMSE > 22 (P = 0.01, Fisher's exact test). No patient with a MMSE < 20 passed the driving test. The authors recommend that health care professionals who are caring for people with Alzheimer's disease with a MMSE of22 or less should request a driving evaluation.
A generalized Markov chain model for effective analysis of slotted IEEE 802.15.4

A generalized analysis of the IEEE 802.15. 4 medium access control (MAC) protocol in terms of reliability, delay and energy consumption is presented. The IEEE 802.15. 4 exponential backoff process is modeled through a Markov chain taking into account retry limits, acknowledgements, and unsaturated traffic. Simple and effective approximations of the reliability, delay and energy consumption under low traffic regime are proposed. It is demonstrated that the delay distribution of IEEE 802.15. 4 depends mainly on MAC parameters and collision probability. In addition, the impact of MAC parameters on the performance metrics is analyzed. The analysis is more general and gives more accurate results than existing methods in the literature. Monte Carlo simulations confirm that the proposed approximations offer a satisfactory accuracy.
Reliability of a CAD/CAM Surgical Guide for Implant Placement: An In Vitro Comparison of Surgeons' Experience Levels and Implant Sites.

PURPOSE This in vitro study evaluated the reliability of a surgical guide with regard to different levels of operator surgical experience and implant site. MATERIALS AND METHODS A stereolithographic surgical guide for epoxy resin mandibles with three edentulous molar sites was produced using a computer-aided design/computer-assisted manufacture (CAD/CAM) system. Two surgeons with and two surgeons without implant surgery experience placed implants in a model either using or not using the CAD/CAM surgical guide. Four groups were created: inexperienced surgeon without the guide (group 1); experienced surgeon without the guide (group 2); inexperienced surgeon with the guide (group 3); and experienced surgeon with the guide (group 4). Planned implants and placed implants were superimposed using digital software, and deviation parameters were calculated. RESULTS There were no significant differences in any of the deviation parameters between the groups when using the surgical guide. With respect to the implant sites, there were no significant differences among the groups in any parameter. CONCLUSION Use of the CAD/CAM surgical guide reduced discrepancies among operators performing implant surgery regardless of their level of experience. Whether or not the guide was used, differences in the anterior-posterior implant site in the molar area did not affect the accuracy of implant placement.
Electronic differential for electric vehicle with evenly split torque

In this paper, an electronic differential is introduced for an electric vehicle (EV) with rear wheel drive and two electric motors. The proposed architecture consists of driving the two motors by simple motor torque controllers, through splitting the torque equally for each motor. The principle is similar to that of a mechanical differential. The purpose is the improvement of EV's drivetrain efficiency and therefore the vehicle's range. A 3 Degree of Freedom (DoF) model, including lateral and longitudinal weight shift and tyre dynamics is created. The aim is to study the effect of traction of each wheel in the vehicle dynamics and its cornering performance.
Propiedades psicométricas del Cuestionario de los Cinco Factores para Niños (BFQ-C) en una muestra de adolescentes argentinos

Resumen Este artículo presenta los estudios psicométricos de la versión española del Cuestionario de los Cinco Factores para Niños (Big Five Questionnaire—Children, BFQ-C) en una muestra de 598 adolescentes Argentinos entre 13 y 15 años. Los resultados muestran cómo una solución pentafactorial es la más adecuada para nuestra población. Sin embargo, varios de los ítems presentan pesos factoriales compartidos por dos o más factores, generando una estructura factorial compleja. El análisis factorial confirmatorio demostró que la estructura de cinco factores se ajusta a los datos solo cuando se utilizó subtest de ítems como indicadores. La consistencia interna y estabilidad temporal de los cinco factores fueron adecuadas. Se realizaron estudios de diferencia entre grupos según el sexo, y de validez predictiva en relación al rendimiento académico y el absentismo injustificado. En este último estudio, los rasgos Responsabilidad, Intelecto/Apertura y Extraversión contribuyeron a predecir el rendimiento académico, mientras que en el caso del absentismo injustificado, sólo el factor Responsabilidad. Se planifican nuevos estudios de estructura factorial del BFQ-C mediante análisis factorial exploratorio y confirmatorio.
PATHOLOGY OF PERIPHERAL NERVE

As with so many studies requiring close clinicopathological correlation and specialised techniques, many of the major contributions to peripheral nevre pathology have been made by clinicians rather than pathologists. As a result, the general pathologist has tended to ignore many of the recent advances in peripheral nerve pathology and trainees in pathology often fail to appreciate that with relatively simple techniques, much information can be gained from the histological study of peripheral nerves.
