Physical fitness, academic achievement, and socioeconomic status in school-aged youth.

BACKGROUND This study examined the association between physical fitness and academic achievement and determined the influence of socioeconomic status (SES) on the association between fitness and academic achievement in school-aged youth. METHODS Overall, 1,701 third-, sixth-, and ninth-grade students from 5 school districts participated in the assessments. Fitness was assessed using FITNESSGRAM (aerobic fitness, muscular strength, muscular endurance, flexibility, and body composition). Results were used to determine individual fitness scores. Academic achievement was measured by standardized tests for Math (all grades), English (all grades), and Social Studies (sixth and ninth grades only). The SES was determined using eligibility for free and reduced lunch program. RESULTS There were no significant differences between fitness groups for Math and English in third-grade students. Sixth- and ninth-grade students with high fitness scored significantly better on Math and Social Studies tests compared with less fit students. Lower SES students scored significantly worse on all tests. Muscular strength and muscular endurance were significantly associated with academic achievement in all grades. CONCLUSIONS Compared with all other variables, SES appears to have the strongest association with academic achievement. However, it also appears that high fitness levels are positively associated with academic achievement in school-aged youth.
French-English Cross-Linguistic Comparison and Diagnostic Impact of the AD-8 Dementia Screening Questionnaire in a Geriatric Assessment Clinic

The AD-8 dementia screening questionnaire is a novel tool that allows clinicians to assess changes in cognitive function. This study examined psychometric properties of the test in French-speaking and English-speaking patients, and its impact on diagnostic practice in the geriatric assessment clinics of a university health centre. Data were extracted from the clinical database for all new patients screened for cognitive impairment 15 months before (historic control group) and 15 months after the introduction of the test (AD-8 group and concurrent control group). Analysis of differential item functioning revealed formal equivalence of the French- and English-language items, supporting the validity of the French version. Respondent type significantly influenced the total score on the AD-8. Concurrent validity with other cognitive screening tests was moderately high. Finally, among patients who did not present with pre-existing dementia, a higher proportion of dementia diagnoses was made in those administered the AD-8 relative to the concurrent control group. Implications for clinical use of the AD-8 are discussed.
Mean Beck Depression Inventory-II Total Scores by Type of Bipolar Episode

The 1996 Beck Depression Inventory-II was administered to 120 outpatients diagnosed with DSM-IV-TR bipolar I disorders who had recently experienced manic, mixed, or depressed episodes. A focused contrast supported the hypothesis that the mean Beck-II total score for the 40 patients with depressed episodes (M = 34.1, SD = 13.2) was higher than the mean Beck-II total score for the 40 patients with mixed episodes (M = 25.9, SD = 13.6) which was, in turn, higher than the mean Beck-II total score for the 40 patients with manic episodes (M = 11.7, SD = 7.8, p <.001). The Beck Depression Inventory-II appears to be useful for measuring self-reported depression in patients with bipolar I disorders.
Performance Improvement of OFDM by 2-Dimensional Wavelet Transform in Flat Fading Channel

In this paper, a new structure was proposed by replacing the blocks of the fast Haar Wavelet Transform (WT) with a two dimensional wavelet transform at the transmitter and the receiver sides in the Orthogonal Frequency Division Multiplexing (OFDM) model. This can be done by converting a 1-Dimensional vector into a 2-dimentional matrix and process it by 2Dimentional wavelet transform (2-DWT). The proposed method was applied on the OFDM in Additive White Gaussian Noise (AWGN) and flat fading channel. It was concluded that the proposed method gives much better Bit Error Rate (BER) performance than the conventional OFDM model based on WT. The simulation results showed that the new structure outperforms the other scheme in the carried tests at the AWGN and flat fading channels. General Terms Algorithms, Performance, Design, Theory.
The Significance and Measurement of Trust in the Organization in the Light of the Empirical Studies

The fact that the problem of trust inside and between organizations as well as on the macro scale is becoming more and more important shows that it is a crucial element of management. A selection of the optimal solution requires having absolute trust in the other party. Trust underlies all business relations in the days of modern technology which facilitate an activity in the geographic space without limits. The research points to the relation between an enterprise’s results, its innovation and competitiveness and the level of corporate trust. This article presents the measurement and analysis of trust in a group of 262 respondents. The following dimensions of trust inside organizations were taken into account: institutional, vertical and horizontal trust. Different aspects of trust depending on the respondent’s particulars and a represented company were also analyzed.
An implicit characterisation of the polynomial hierarchy in an unbounded arithmetic

Today, there are countless approaches towards characterising complexity classes via logic. Foremost amongst these lies the proof-theoretic approach, characterising classes as the ‘representable’ functions of some logic or theory. Examples include bounded arithmetic [6] [13] [9], applicative theories [7] [12], intrinsic and ramified theories [16] [4], fragments of linear logic [11] [10] [14] [1] and fragments of intuitionistic logic [15]. To some extent there is a distinction between various notions of ‘representability’, namely between logics that type terms computing functions of a given complexity class, and theories that prove the totality or convergence of programs computing functions in a given complexity class. A somewhat orthogonal distinction is whether the constraints on the logic or theory are implicit or explicit. The former includes constraints such as ramification, type level and substructural considerations, while the latter includes bounded quantification, bounded modalities etc. This distinction is also naturally exhibited in associated function algebras, e.g. Cobham’s limited recursion on notation [8] vs. Bellantoni and Cook’s predicative recursion on notation [3]. While implicit constraints may be preferable since no bounds occur in the characterisation itself per se, explicit bounds are typically far more useful for more fine-grained characterisations of complexity classes. For instance, the polynomial hierarchy, PH, and its levels can be neatly characterised by the theories S 2 of bounded arithmetic, using bounds on quantifiers to control complexity [6]. 1 In this work we improve the situation by using implicit methods in first-order theories to characterise PH. To achieve this we work with a function algebra of Bellantoni from [5] in which to extract programs, and use the witness function method of Buss to extract programs at ground type and preserve quantifier information, necessary to delineate the levels of PH.
Crip Technoscience Manifesto

As disabled people engaged in disability community, activism, and scholarship, our collective experiences and histories have taught us that we are effective agents of world building and dismantling toward more socially just relations.The grounds for social justice and world remaking, however, are frictioned;technologies, architectures, and infrastructures are often designed and implemented without committing to disability as a difference that matters. This manifesto calls attention to the powerful, messy, non-innocent, contradictory, and nevertheless crucial work of what we name as “crip technoscience,” practices of critique, alteration, and reinvention of our material-discursive world. Disabled people are experts and designers of everyday life. But we also harness technoscience for political action, refusing to comply with demands to cure, fix, or eliminate disability. Attentive to the intersectional workings of power and privilege, we agitate against independence and productivity as requirements for existence. Instead, we center technoscientific activism and critical design practices that foster disability justice.
So what is an optimal test mix? A discussion of the SEMATECH methods experiment

The SEMATECH "Test Methods Evaluation" study, Project Number S-121, is an experiment to determine the relative merits of several test methodologies often used by SEMATECH member companies and other IC manufacturers. Conclusions drawn from the experiment thus far have indicated that each test methodology uniquely detects defects. This experimentation and analysis would not have been possible outside a consortium setting such as SEMATECH. Its conclusions may affect other major segments of the industry, including ATE manufacturers, CAD vendors, and academia. This paper gives a brief overview of the experiment and summarizes its findings.
Thermal gelation and tissue adhesion of biomimetic hydrogels

Marine and freshwater mussels are notorious foulers of natural and manmade surfaces, secreting specialized protein adhesives for rapid and durable attachment to wet substrates. Given the strong and water-resistant nature of mussel adhesive proteins, significant potential exists for mimicking their adhesive characteristics in bioinspired synthetic polymer materials. An important component of these proteins is L-3,4-dihydroxylphenylalanine (DOPA), an amino acid believed to contribute to mussel glue solidification through oxidation and crosslinking reactions. Synthetic polymers containing DOPA residues have previously been shown to crosslink into hydrogels upon the introduction of oxidizing reagents. Here we introduce a strategy for stimuli responsive gel formation of mussel adhesive protein mimetic polymers. Lipid vesicles with a bilayer melting transition of 37 °C were designed from a mixture of dipalmitoyl and dimyristoyl phosphatidylcholines and exploited for the release of a sequestered oxidizing reagent upon heating from ambient to physiologic temperature. Colorimetric studies indicated that sodium-periodate-loaded liposomes released their cargo at the phase transition temperature, and when used in conjunction with a DOPA-functionalized poly(ethylene glycol) polymer gave rise to rapid solidification of a crosslinked polymer hydrogel. The tissue adhesive properties of this biomimetic system were determined by in situ thermal gelation of liposome/polymer hydrogel between two porcine dermal tissue surfaces. Bond strength measurements showed that the bond formed by the adhesive hydrogel (mean = 35.1 kPa, SD = 12.5 kPa, n = 11) was several times stronger than a fibrin glue control tested under the same conditions. The results suggest a possible use of this biomimetic strategy for repair of soft tissues.
Sichere Flugpfade unbemannter Flugzeuge durch Anlayse von Trajektorien und Rückführung von Modellparametern auf die Bahnplanung

In dieser Arbeit wird ein Ansatz zu einer adaptiven, auf die automatisierte Analyse von geflogenen Trajektorien unbemannter Flugzeuge gestutzte Bahnplanung prasentiert. Dazu werden Algorithmen vorgestellt, die auf Basis von gemessenen Positionen Trajektorien in einzelne Kurs- und Hohenanderungen unterteilen und bahnplanungsrelevante Parameter wie extremale Bahnwinkel und minimale Kurvenradien approximieren. Anschliesend werden aus den ermittelten Bahnwinkeln und Kurvenradien automatisch an die Kinematik des Flugzeugs angepasste Parameter fur eine Neuplanung der Flugbahn gewahlt. Horizontale und vertikale Bahnablagen werden ebenfalls betrachtet und als adaptive Sicherheitsabstande fur die Gewahrleistung eines kollisionsfreien Fluges verwendet. Der Ansatz wird auf der Basis von simulierten und realen Flugdaten evaluiert.
Evaluation of reference values of standard semen parameters in fertile Egyptian men

The reference values of human semen, published in the WHO's latest edition in 2010, were lower than those previously reported. The objective of this study was to evaluate reference values of standard semen parameters in fertile Egyptian men. This cross‐sectional study included 240 fertile men. Men were considered fertile when their wives had recent spontaneous pregnancies with time to pregnancy (TTP) ≤12 months. The mean age of fertile men was 33.8 ± 0.5 years (range 20–55 years). The 5th percentiles (95% confidence interval) of macroscopic semen parameters were 1.5 ml for volume and 7.2 for pH. The 5th percentiles of microscopic parameters were 15 million/ml for sperm concentration, 30 million per ejaculate for total sperm count, 50% for total motility, 40% for progressive motility, 62% for vitality, 4% for normal sperm forms and 0.1 million/ml for seminal leucocyte counts. In conclusion, fertile Egyptian men had higher reference values of sperm total motility, progressive motility and vitality, and lower reference values for total sperm counts as compared to those determined by the latest edition of the WHO laboratory manual in 2010. Other semen parameters were identical to those defined by the WHO 2010 manual.
Developmental expression of the murine Mopb gene

In this report we describe the developmental expression of the murine (Mobp) gene encoding myelin‐associated oligodendrocytic basic protein. We have characterized three Mobp cDNA clones which have been used as probes. Murine Mobp splice variant‐1 (mmsv‐1), a portion of 3′ untranslated region (UTR), is homologous to 3′ UTR sequences found in the rat Mobp splice variants rOP1, Mobp81‐A and Mobp‐99. The mmsv‐2 sequence, encoding 81 amino acids, closely resembles the rat Mobp81‐A splice variant. The mmsv‐3 cDNA, encoding 170 amino acids corresponding closely to the rat rOPRP1 splice variant, detects a single mRNA species present in low levels from E12 onward, suggesting this MOBP may have a function alternative or additional to involvement in myelin formation. The mmsv‐1 probe detects an mRNA species abundantly expressed in the postnatal central nervous system (CNS) but barely detectable at E18. This mRNA is located initially in the cell bodies of oligodendrocytes, moving distally into their processes as myelination proceeds. The most abundant mmsv(s) in the adult CNS are present at detectable levels after expression of the myelin basic protein (Mbp) gene and marginally after or coincident with the proteolipid protein (Plp) gene. The level of the abundant, late‐expressed mRNA correlates closely with the capacity to form myelin and the maturity of oligodendrocytes, as shown in two hypomyelinated mutants, rumpshaker and jimpy, which represent mildly and severely affected phenotypes, respectively.

THE INTEGRATION OF PIGMEAT MARKETS IN THE EU. EVIDENCE FROM A REGULAR MIXED VINE COPULA

The objective of this work is to investigate the degree of integration of national pigmeat markets in the EU. This is pursued using monthly wholesale prices from seven major markets and the statistical tool of mixed R-vine copulas. The empirical results suggest that the markets considered do not constitute a great pool in which prices move, boom, and crash together. The markets of Belgium, Germany, and the Netherlands exhibit a higher degree of integration relative to the others, whereas the Italian market exhibits a lower degree of integration. Also, there is an indication that, in certain cases, the benefits of free trade may be unequally distributed between the trading partners.
Variability in tactile projection patterns to cerebellar folia crus IIa of the norway rat

Tactile responses in the granule cell layers of the cerebellar hemispheres of rats are topographically arranged as a series of patches each representing a different region of the body surface. Previous observations had suggested that patches representing specific body parts recur in similar folial positions in different individuals; however, these relationships were not quantified. In this study we make inter‐animal comparisons of the detailed distribution of receptive fields in the granule cell layer of the crown of crus IIa by using physiological mapping techniques. The results suggest that maps from different individuals do, in fact, share several topological features. These include the regions of the body surface represented, the general proportions of these representations, the relative positions of patches representing the same body parts, and the organization of receptive fields within patches located in similar positions. The principal variability seen in these comparisons was in the detailed neighborhood relations between different patches. As a result of the analysis of the consistent and variable features of these maps, we propose and discuss a new role for these cerebellar regions in coordinating the acquisition of tactile sensory information.
Implementation and Evaluation of a Parallel Algorithm for Structure Learning in Bayesian Networks

This thesis is about learning the globally optimal Bayesian network structure from fully observed dataset, by using score-based method. This structure learning problem is NP- hard, and has attracted the attention of many researchers. We first introduce the necessary background of the problem, then review various score-based methods and algorithms proposed in solving the problem. Parallelization has come under the spotlight during recent years, as it can utilize shared memory and computing power of multi-core supercomputers or computer clusters. We implemented a parallel algorithm Para-OS, which is based on dynamic programming. Experiments were performed in order to evaluate the algorithm. We also propose an improved version of Para-OS, which separates the scoring phase totally from the learning phase, performs score pruning by using Sparse Parent Graph, in addition largely reduces the communication between processors. Empirical results shows the new version saves memory comparing to Para-OS, and provides good runtime with multi-treading.
Human Internal Disc Strains in Axial Compression Measured Noninvasively Using Magnetic Resonance Imaging

Study Design. Internal deformations and strains were measured within intact human motion segments. Objective. Quantify 2-dimensional internal deformation and strain in compression of human intervertebral discs using MRI. Summary of Background Data. Experiments using radiographic or optical imaging have provided important data for internal disc deformations. However, these studies are limited by physical markers and/or disruption of the disc structural integrity. Methods. MR images were acquired before and during application of a 1000 N axial compression. Two-dimensional internal displacements, average strains, and the location and direction of peak strains were calculated using texture correlation, a pattern matching algorithm. Results. The average height loss was 0.4 mm, which corresponded to 4.4% compressive strain. The inner AF radial displacement was outward, even with degeneration; the average outward displacement of the inner AF (0.16 mm) was less than the outer AF (0.36 mm). High shear peak strains (2%–26%) occurred near the endplate and at the inner AF. Shear was higher in the anterior AF compared to the posterior. Conclusion. This technique allows quantification of displacement and strain within the intact disc. The radial displacements of inner AF suggest NP translation under compression. Peak tensile radial strains occurred as vertical bands throughout the anulus, which may contribute to radial tears and herniations. The tensile axial and shear strains at the interface between the AF and endplate could be related to the occurrence of rim lesions. Peak strains at the endplate are likely due to the AF curvature and the oblique fibers angle at fiber insertion sites. In the future, this technique may be used to measure disc strain under a variety of loading conditions, such as bending or torsion, and could also be used to study the mechanical effects of disc degeneration and potential clinical interventions.
Total Curve Analysis of Regional Cerebral Blood Flow with 133Xe Inhalation: Description of Method and Values Obtained with Normal Volunteers

Regional cerebral blood flow (rCBF) is studied by the 133Xe inhalation method. A mathematical function related to radiation originating from air passages, which contaminates the desired signal, is proposed. Its incorporation into the theoretical model permits use of the entire recorded head curve in subsequent least-squares analyses. Results from this total curve analysis are compared with results from the standard model of Obrist et al. [2] for four normal rest studies performed on each of nine healthy volunteers.
Reliability of Magnetic Resonance Imaging Performed After Intratympanic Administration of Gadolinium in the Identification of Endolymphatic Hydrops in Patients With Ménière's Disease

Objective: To evaluate the reliability of magnetic resonance imaging performed after intratympanic gadolinium administration in evidencing endolymphatic hydrops in patients with Ménière's disease (MD). Patients: A total of 26 patients (18 male and 8 female subjects, aged 25-78 yr; median age, 56 yr) with definite MD and 12 subjects (8 male and 4 female subjects, aged 31-75 yr; median age, 51 yr) with various unilateral non-MD disorders of the inner ear were examined. Intervention: A 0.6-ml solution of gadobutrol (1 mmol/ml), diluted 1:7 in saline, was injected in the affected ear through the inferior-posterior quadrant of the tympanic membrane, using a 22-gauge spinal needle. In 9 MD patients, the contralateral ear also was injected. The patient was kept with the head rotated 45 degrees contralaterally for 30 minutes after each injection. Twenty-four hours later, a 3-dimensional fluid-attenuated inversion recovery magnetic resonance imaging using a 3 Tesla unit was performed. Main Outcome Measure: Perilymphatic enhancement was evaluated in different portions of the labyrinth in MD ears and compared with the outcomes obtained in the non-MD ears. Results: All MD ears showed impaired perilymphatic enhancement of variable degrees. No enhancement defects could be observed in all examined contralateral unaffected ear of the patients with MD, as well as in 11 of the 12 ears of the subjects with various unilateral non-MD disorders. Conclusion: Perilymphatic enhancement defect of variable degrees is observed in the pathologic ear of every patient with MD. The consistency of this phenomenon in MD ears and the complete enhancement in most of the ears without MD safely enable to attribute these findings to endolymphatic hydrops. It is likely in the near future that imaging may be used to achieve a certain diagnosis of MD in life.
Requirements on automotive radar systems for enhanced pedestrian protection

This paper work is connected to the joint EU-project called ARTRAC. It briefly describes one of the first project tasks in which the requirements are derived that are necessary for enhanced pedestrian protection for a single radar system. Therefore, we examine different points of view: accident statistics and the associated environmental circumstances, user needs for active safety systems and radar regulations. The resulting technical requirements are compared to current automotive radar systems, while reviewing the feasibility. In addition we discuss how a new transmit/ receive antenna and multi-channel receiver should be developed and give examples for possible safety functions that could benefit from this innovative radar sensor.
