Respiratory Variability and Psychological Well-Being in Schoolchildren

Among the relations between respiration and psychological state, associations with respiratory variability have been contradictory. In this study, respiration was measured noninvasively in 162 children with a mean age of 11 years (from 9 to 13). They completed a battery of psychological tests. Structural Equation Modeling (SEM or LISREL) revealed a model that fit the data well (X2 = 88.201, df = 79, p = .224). In this model, respiratory variability was positively related to anger-in and negatively to negative fear of failure and neurotic complaints. Respiration rate was positively related to positive fear of failure, and duty cycle was positively related to the latent variable of negative affect. Variability in resting time components of respiration was higher among children with less fear of failure and fewer complaints. Therefore, respiratory variability need not necessarily be a sign of psychological dysfunctions, and interventions should not always impose a fixed breathing pattern.
Comparison of event-related potentials between conceptually similar Chinese words and pictures

The purpose of this study was to examine the effects of conceptual similarity between target and nontarget stimuli on P300 component during a multistimulus oddball paradigm. P300 is an endogenous component of event related potentials, which can reflect the information processing of brain. It is elicited in two-stimulus oddball task in this report. The stimuli were pictures of three objects and their corresponding Chinese words and English words. Participants were required to keep a mental count of number of target presentations. In experiment 1, the target was the picture “bag”, the Chinese word was considered to be the related nontarget, others were nontarget, the target elicited a large p300, the related nontarget stimulus and nontarget failed to elicit a p300. In experiment 2, the target was the Chinese word of bag, the picture was considered to the related nontarget, others were nontarget. Both the word target and the nontarget picture elicited large p300s, though the p300 to the related nontarget was smaller in amplitude. In this work, the experiments elucidate that imagery and verbal information are processed by distinct but interconnected systems.
Assessment of Subclinical Vascular Disease Associated with Ankylosing Spondylitis

Objective. Studies indicate that ankylosing spondylitis (AS), as well as rheumatoid arthritis, may be associated with accelerated atherosclerosis and vascular disease. We assessed endothelial dysfunction, carotid atherosclerosis, and aortic stiffness in AS in context with clinical and laboratory measurements. Methods. Forty-three patients with AS and 40 matched healthy controls were studied. We assessed common carotid intima-media thickness (ccIMT), flow-mediated vasodilation (FMD), and pulse-wave velocity (PWV) in association with age, disease duration, smoking habits, body mass index, patient’s assessment of pain and disease activity, Bath AS Disease Activity Index, Bath AS Functional Index (BASFI), metric measurements, erythrocyte sedimentation rate, C-reactive protein, and HLA-B27 status. Results. We found impaired FMD (6.85 ± 2.98% vs 8.30 ± 3.96%; p = 0.005), increased ccIMT (0.65 ± 0.15 vs 0.54 ± 0.15 mm; p = 0.01), and higher PWV (8.64 ± 2.44 vs 8.00 ± 1.46 m/s; p = 0.03) in patients with AS compared to controls, respectively. We also found that ccIMT negatively correlated with FMD (r = −0.563; p = 0.0001) and positively correlated with PWV (r = 0.374; p = 0.018). Both ccIMT and PWV correlated with disease duration (r = 0.559; p = 0.013 and r = 0.520; p = 0.022, respectively), BASFI (r = 0.691; p = 0.003 and r = 0.654; p = 0.006), decreased lumbar spine mobility (r = −0.656; p = 0.006 and r = −0.604; p = 0.013), chest expansion (r = −0.502; p = 0.047 and r = −0.613; p = 0.012), and increased wall-occiput distance (r = 0.509; p = 0.044 and r = 0.614; p = 0.011). Conclusion. In this well characterized AS population, impaired FMD and increased ccIMT and PWV indicate abnormal endothelial function and increased atherosclerosis and aortic stiffness, respectively. The value of noninvasive diagnostic tools needs to be further characterized.
Comparison on Two Analysis Methods of Strategic Network: Whole and Dyad Network Analysis

Relational attribute and structure attribute are the two main attributes of firm's network. Most researchers' works are based on them. We compared the two analysis methods and found that there are different effects by using difference analysis method. The dyad analysis method can give a focus and deep view of the relations. And the whole network analysis method can provide a whole and integrated understanding of the network's function.
A Multihybrid FE-BI-KA Technique for 3-D Electromagnetic Scattering From a Coated Object Above a Conductive Rough Surface

A multihybrid method combining numerical vector finite-element method/boundary integral method (FEM/BIM) and analytic Kirchhoff approximation (KA) is developed to study electromagnetic scattering from a 3-D coated target above 2-D conductive randomly rough surface. The hybrid vector FEM/BIM is applied to model scattering from the coated target, while the scattering from the rough surface is studied by KA, which can greatly reduce the computation time and memory requirement. An iterative approach is adopted to take into account the interaction between the target and underlying rough surface. The electric fields integral equations of the induced difference current on the rough surface and the induced electric and magnetic currents on the surface of the target are derived based on green's function and the boundary conditions. Our numerical code is validated by the commercial software. The convergence and the iteration error of the multihybrid method are discussed. Using the Monte Carlo method to generate 2-D Gaussian rough surface, bistatic difference field radar cross section of a 3-D coated sphere above a 2-D conductive rough surface is numerically simulated.
Multiple preverbation in Homeric Greek: A typological insight

This paper analyses the system of multiple affixation of spatial preverbs in Homeric Greek in a typological perspective, based on Talmy’s (2000) typology of Motion event, on the work done within the Trajectoire Project (CNRS, TUL), and work on (multiple) affixation systems in some Amerindian languages (Craig & Hale 1988; Craig 1993; Grinevald 2003). It details the existence in Homeric Greek of a set of relational preverbs functionally distinct from the more widely-known “satellite” preverbs, and the existence of interesting semantic affix-order constraints on their multiple affixation on the verb stem. Throughout, the analysis focuses on the motivated and function-driven interconnection between the morphosyntactic patterning and the semantic constraints affecting this system.
Individuality and Contextual Influences on Drug Dependence: A 15-Year Prospective Longitudinal Study of Adolescents From Harlem

ABSTRACT In this 15-year longitudinal study the authors investigated individual and contextual factors that predispose adolescents from a disadvantaged urban area to drug dependence in adulthood. Adolescents were recruited from schools serving East Harlem in New York City. Of the 838 participants followed to adulthood, 59% were women, 55% were African American, and 45% were Puerto Rican. Self-report data were obtained on externalizing and internalizing problems, substance use, and contextual influences across adolescence and young adulthood. Drug dependence was assessed in adulthood. Multivariate logistic regressions of drug dependence were performed on the whole sample and separately by gender. Each of the domains was associated with adult drug dependence. Although mean gender differences were found, most associations of risk factors with drug dependence did not vary significantly by gender. Treating externalizing and internalizing problems, reducing substance use, and providing coping skills for adverse contextual influences in adolescence and young adulthood may reduce the likelihood of becoming drug dependent in adulthood.
Sonographically observed echogenic response during intraoperative radiofrequency ablation of cirrhotic livers: pathologic correlation.

OBJECTIVE We performed a study to determine the correlation between the diameter of the echogenic response observed with intraoperative sonography during radiofrequency ablation of the cirrhotic liver and the mean diameter of tissue necrosis. SUBJECTS AND METHODS A total of 22 intraoperative radiofrequency ablations were created in 11 cirrhotic livers. The largest diameter of the sonographically observed echogenic response surrounding and perpendicular to the radiofrequency probe was measured. The subsequent zone of necrosis observed at pathology in the hepatectomy specimens after liver transplantation was measured in three planes and compared with the measured diameter of the echogenic response. RESULTS During all except three ablations, a hyperechoic region was visualized surrounding the radiofrequency probe. The diameter of the echogenic response correlated significantly with the mean diameter of necrosis (correlation coefficient, 0.84). However, the echogenic response overestimated the minimal diameter of necrosis (mean difference, 0.8 +/- 0.4 cm) in 18 of 22 ablations and underestimated the maximum diameter of necrosis (mean difference, 0.9 +/- 0.8 cm) in 16 of 22 ablations. CONCLUSION The diameter of the echogenic response observed with intraoperative sonography during radiofrequency ablation of the cirrhotic liver correlates closely with the mean diameter of the subsequent area of tissue necrosis. However, the solitary diameter of the echogenic response as measured in our study was often greater than the smallest diameter and less than the largest diameter of the area of tissue necrosis. Therefore, the echogenic response associated with radiofrequency ablation of the cirrhotic liver should be viewed only as a rough approximation of the area of induced tissue necrosis; the final assessment of the adequacy of ablation should be deferred to an alternative imaging technique.
Fully automatic face recognition from 3D videos

Almost all of the existing research on 3D face recognition is based on static 3D images. 3D videos are believed to provide more information in terms of both the shape as well as the dynamics of an individual's face. This paper presents a system which exploits the spatiotemporal information in 3D videos for the task of face recognition. An algorithm for automatic normalization of raw 3D videos is also given. After the detection of the nose tip, all meshes of the 3D video are cropped and uniformly sampled to form range videos. Spatiotemporal Local Binary Pattern (LBP) descriptors are used for feature extraction from the range videos. For classification, a linear multiclass Support Vector Machine (SVM) is used. The system is trained on videos of a person with different facial expressions and tested on a video with new facial expression. Experimental results on the largest currently available 3D video database, BU 4DFE, show a high recognition rate of 92.68%.
Excitation energies from time-dependent density-functional formalism for small systems

As a test of the time-dependent local-density approximation (TDLDA), we study the 1Σg+ → 1Σu+ excitation of H2 as a function of the nuclear distance d. We find rather accurate results for intermediate d but not for small and large d. At large d, TDLDA fails due to the strong non-locality and energy dependence of the exact functional. The spin-dependent formalism gives a qualitative improvement for large d. To analyze the results, we compare with the 2s → 2p excitation for He, Li and Be for small and intermediate d and with the Hubbard model for large d. The fairly accurate results for Li and Be are related to the accuracy of the ground-state formalism for a few electrons.
Parameter Estimation for a Bidimensional Partially Observed Ornstein–Uhlenbeck Process with Biological Application

Abstract. We consider a bidimensional Ornstein–Uhlenbeck process to describe the tissue microvascularization in anti‐cancer therapy. Data are discrete, partial and noisy observations of this stochastic differential equation (SDE). Our aim is to estimate the SDE parameters. We use the main advantage of a one‐dimensional observation to obtain an easy way to compute the exact likelihood using the Kalman filter recursion, which allows to implement an easy numerical maximization of the likelihood. Furthermore, we establish the link between the observations and an ARMA process and we deduce the asymptotic properties of the maximum likelihood estimator. We show that this ARMA property can be generalized to a higher dimensional underlying Ornstein–Uhlenbeck diffusion. We compare this estimator with the one obtained by the well‐known expectation maximization algorithm on simulated data. Our estimation methods can be directly applied to other biological contexts such as drug pharmacokinetics or hormone secretions.
Packet-wise compression and forwarding of industrial network captures

Network traffic captures are necessary for a variety of security applications like identification of malicious patterns or training of intrusion detection systems. While monitoring of enterprise networks is common practice, it is rarely done for industrial production environments due to low bandwidth, confidential production data and sensitive legacy components. To address these challenges, we present methods for non-interfering recording, compression, and transmission of industrial network packet captures. Since a large portion of industrial network traffic consists of status reports that change only slightly, we replace recurring byte strings per connection to reduce the data sent, which also provides a form of concealment We evaluate our approach by a prototypical implementation on self-generated and publicly available industrial network captures and compare our substitution algorithm to the standard zlib algorithm as well as a combination of both methods.
Performance analysis of multicast routing protocol PIM-SM

PIM-SM is preferred among the current intradomain multicast routing protocols. But it has not been widely deployed in the Internet until now. To provide suggestions for improving this protocol, we analyze the performance of it in this paper. The characteristic of our analysis is that we use the stochastic Petri net (SPN) model, which is an excellent tool for performance analysis in many areas. Based on the SPN model of PIM-SM we establish for the first time and router realization, we make a performance analysis of PIM-SM according to different message types, finding that the register message and join/prune message cause most router processing load, while the join/prune message and bootstrap message consume most network bandwidth.
Recherche ciblée de documents sur le web

Depuis sa creation, le web a vu sa taille croitre de maniere phenomenale rendant la recherche d'informations difficile et fastidieuse. Cette difficulte est perceptible lorsqu'il s'agit de rechercher des documents complexes tels que des documents thematiques. Ceci se traduit par des reponses nombreuses et souvent imprecises. Il est, dans ce cas, necessaire de recourir a un expert humain pour filtrer les reponses impertinentes. Cette imprecision s'explique par le principe meme du fonctionnement des outils de recherche actuels de documents sur le web. En effet, les requetes mots cles utilises par la plupart des moteurs de recherche sont peu expressives pour caracteriser les documents souhaites. Par ailleurs, les techniques utilisees par ces moteurs pour constituer leur index de documents, sur lequel les requetes sont evaluees, parcourent le web dans le but de rapatrier tout type de documents. Je montre dans cette these que l'heterogeneite des index des moteurs de recherche et leur technique non ciblee pour alimenter ces index peut etre source d'imprecision lors de l'evaluation des requetes. Pour ameliorer la precision de la recherche sur le web, je propose WeQueL, un langage de requetes declaratif et multicriteres. Par ce langage, je montre qu'une facon d'augmenter la precision des requetes mots cles consiste a les combiner sur differentes parties de la structure d'un document. Je propose egalement une approche selective d'exploration du web guidee par une requete WeQueL. Cette approche repose sur une technique d'anticipation du score d'un document sans avoir encore rapatrie son contenu. Pour cela, un systeme d'apprentissage bayesien est mis en place.
Longitudinal Manganese-Enhanced Magnetic Resonance Imaging of Delayed Brain Damage after Hypoxic-Ischemic Injury in the Neonatal Rat

Background: Hypoxia-ischemia (HI) in the neonatal brain results in a prolonged injury process. Longitudinal studies using noninvasive methods can help elucidate the mechanisms behind this process. We have recently demonstrated that manganese-enhanced magnetic resonance imaging (MRI) can depict areas with activated microglia and astrogliosis 7 days after hypoxic-ischemic brain injury. Objective: The current study aimed to follow brain injury after HI in rats longitudinally and compare manganese enhancement of brain areas to the development of injury and presence of reactive astrocytes and microglia. Methods: The Vannucci model for hypoxic-ischemic injury in the neonatal rat was used. Pups were injected with either MnCl2 or saline after 6 h and again on day 41 after HI. Longitudinal MRI (T1 weighted) was performed 1, 3, 7 and 42 days after HI. The brains were prepared for immunohistochemistry after the final MRI. Results: There was severe loss of cerebral tissue from day 7 to day 42 after HI. Most manganese-enhanced areas in the hippocampus, thalamus and basal ganglia at day 7 were liquefied after 42 days. Manganese-enhancement on day 42 corresponded to areas of activated microglia and reactive astrocytes in the remaining cortex, hippocampus and amygdala. However, the main area of enhancement was in the remaining thalamus in a calcified area surrounded by activated microglia and reactive astrocytes. Conclusion: Manganese-enhanced MRI can be a useful tool for in vivo identification of cerebral tissue undergoing delayed cell death and liquefaction after HI. Manganese enhancement at a late stage seems to be related to the accumulation of manganese in calcifications and gliotic tissue.
Nonsurgical or Surgical Treatment of ACL Injuries: Knee Function, Sports Participation, and Knee Reinjury: The Delaware-Oslo ACL Cohort Study.

BACKGROUND While there are many opinions about the expected knee function, sports participation, and risk of knee reinjury following nonsurgical treatment of injuries of the anterior cruciate ligament (ACL), there is a lack of knowledge about the clinical course following nonsurgical treatment compared with that after surgical treatment. METHODS This prospective cohort study included 143 patients with an ACL injury. Isokinetic knee extension and flexion strength and patient-reported knee function as recorded on the International Knee Documentation Committee (IKDC) 2000 form were collected at baseline, six weeks, and two years. Sports participation was reported monthly for two years with use of an online activity survey. Knee reinjuries were reported at the follow-up evaluations and in a monthly online survey. Repeated analysis of variance (ANOVA), generalized estimating equation (GEE) models, and Cox regression analysis were used to analyze group differences in functional outcomes, sports participation, and knee reinjuries, respectively. RESULTS The surgically treated patients (n = 100) were significantly younger, more likely to participate in level-I sports, and less likely to participate in level-II sports prior to injury than the nonsurgically treated patients (n = 43). There were no significant group-by-time effects on functional outcome. The crude analysis showed that surgically treated patients were more likely to sustain a knee reinjury and to participate in level-I sports in the second year of the follow-up period. After propensity score adjustment, these differences were nonsignificant; however, the nonsurgically treated patients were significantly more likely to participate in level-II sports during the first year of the follow-up period and in level-III sports over the two years. After two years, 30% of all patients had an extensor strength deficit, 31% had a flexor strength deficit, 20% had patient-reported knee function below the normal range, and 20% had experienced knee reinjury. CONCLUSIONS There were few differences between the clinical courses following nonsurgical and surgical treatment of ACL injury in this prospective cohort study. Regardless of treatment course, a considerable number of patients did not fully recover following the ACL injury, and future work should focus on improving the outcomes for these patients.

Frequency Offset Estimation with Increased Nyquist Frequency

In wireless communication systems, there is a need to estimate and compensate for frequency offsets. What is common to frequency offset estimators, is that they only can give correct results within a certain range, up to the Nyquist frequency. This makes a difference especially in OFDM systems with pilots only at certain symbols, such as LTE. In this paper we present an algorithm where the Nyquist frequency is increased, up to the same value as if pilots were present in all OFDM symbols. The algorithm is based on using two or more frequency offset estimators, with lower, but different, Nyquist frequencies.
Altered anxiety and depression-related behaviour in mice lacking GABAB(2) receptor subunits

Metabotropic GABAB receptors predominantly function as heterodimers of GABAB(1) and GABAB(2) subunits, but GABAB(1) can also form functional receptors in the absence of GABAB(2). Mice lacking the GABAB(1) subunit have altered behavioural responses in tests for anxiety and depression. In these studies, we investigated anxiety and depression in GABAB(2)-deficient mice. We compared the effects directly with that of genetic deletion of the GABAB(1) receptor subunit. Both GABAB(1) and GABAB(2)-deficient mice were found to be more anxious than wild type in the light–dark box paradigm. In contrast, these mice exhibited an antidepressant-like behaviour in the forced swim test. Taken together, these data suggest that heterodimeric GABAB(1,2) receptors are required for the normal regulation of emotional behaviour.
Anterior Cingulate Volumetric Alterations in Treatment-Naïve Adults With ADHD

Objective: We sought to examine preliminary results of brain alterations in anterior cingulate cortex (ACC) in treatment-naïve adults with ADHD. The ACC is a central brain node for the integration of cognitive control and allocation of attention, affect and drive. Thus its anatomical alteration may give rise to impulsivity, hyperactivity and inattention, which are cardinal behavioral manifestations of ADHD. Method: Segmentation and parcellation of the ACC was performed on controls (n = 22), treated (n = 13) and treatment-naïve adults with ADHD (n = 13). Results: There was a 21% volume reduction in the left ACC of the treatment-naïve group relative to the control group. Also, there was a 23% volume reduction in the right ACC of the treated group relative to the control group. Conclusion: These results raise the possibility that in ADHD there are volumetric deficits persistent into adulthood, that are independent of medical treatment. (J. of Att. Dis. 2010; 13(4) 407-413)
