Improving accuracy for TVWS geolocation databases: Results from measurement-driven estimation approaches

Recent advances towards opening underutilized spectrum resources for secondary use rely on geolocation databases to determine protection requirements of primary users. This paper studies the achievable accuracy of signal strength estimation for a primary TV network with log-normal propagation models, linear interpolation through Delaunay triangulation, and ordinary kriging as means of including measurement data into a database's prediction process. Direct estimation methods are compared against hybrid mixture models of statistical propagation modelling with interpolation of the error surface. The results presented herein use measurements from a large-scale measurement campaign in the UK. They show that relatively small data sets suffice to achieve mean absolute prediction errors of 3.1-5.0dB compared to 5.9-6.9dB achieved by purely terrain-based estimation approaches.
The Effect of Uniaxial Cyclic Deformation on the Evolution of Phase Transformation Fronts in Pseudoelastic NiTi Wire

Experiments are presented of the response of pseudoelastic NiTi wires subjected to displacement controlled cycles. A custom-built thermo-mechanical testing apparatus is used to control the background temperature field of the wire specimen while allowing the evolution of transformation fronts to be tracked by full-field infrared imaging. Two experiments under similar end-displacement histories, but at temperatures approximately 8°C apart, are shown to give remarkably different cyclic responses. The mechanical response for the lower temperature experiment continued to soften but retained its shape through 43 partial transformation cycles, and the pattern of transformation fronts seemed to reach a steady state. The response for the higher temperature experiment showed a change in shape of the mechanical response and distinct changes in transformation front patterns over 31 partial transformation cycles.
Single chords convey distinct emotional qualities to both naïve and expert listeners

Previous research on music and emotions has been able to pinpoint many structural features conveying emotions. Empirical research on vertical harmony’s emotional qualities, however, has been rare. The main studies in harmony and emotions usually concern the horizontal aspects of harmony, ignoring emotional qualities of chords as such. An empirical experiment was conducted where participants (N = 269) evaluated pre-chosen chords on a 9-item scale of given emotional dimensions. 14 different chords (major, minor, diminished, augmented triads and dominant, major and minor seventh chords with inversions) were played with two distinct timbres (piano and strings). The results suggest significant differences in emotion perception across chords. These were consistent with notions about musical conventions, while providing novel data on how seventh chords affect emotion perception. The inversions and timbre also contributed to the evaluations. Moreover, certain chords played on the strings scored moderately high on the dimension of ‘nostalgia/longing,’ which is usually held as a musical emotion rising only from extra-musical connotations and conditioning, not intrinsically from the structural features of the music. The role of background variables to the results was largely negligible, suggesting the capacity of vertical harmony to convey distinct emotional qualities to both naïve and expert listeners.

COLLEGIATE ATHLETIC ASSOCIATION DIVISION I WOMEN’S BASKETBALL PLAYERS

Egan, A.D., J.T. Cramer, L.L. Massey, and S.M. Marek. Acute effects of static stretching on peak torque and mean power output in National Collegiate Athletic Association Division I women’s basketball players. J. Strength Cond. Res. 20(4): 778–782. 2006. —The purpose of this study was to examine the acute effects of static stretching on peak torque (PT) and mean power output (MP) during maximal, voluntary concentric isokinetic leg extensions at 60 and 300 ·s 1 in National Collegiate Athletic Association Division I Women’s Basketball players. Eleven members of a women’s basketball team volunteered to perform maximal concentric isokinetic leg extensions at 60 and 300 ·s 1 on a calibrated Biodex System 3 dynamometer. After the initial isokinetic testing, the dominant leg extensors were stretched using 1 unassisted and 3 assisted static stretching exercises. The poststretching isokinetic assessments were repeated at 5, 15, 30, and 45 minutes after the static stretching (post-5, post-15, post-30, and post-45). PT (N·m) and MP (W) were recorded by dynamometer software. The results indicated no stretching-related changes in PT (p 0.161) or MP (p 0.088) from preto poststretching for any of the testing intervals (post5, post-15, post-30, and post-45). These findings indicated that the static stretching had no impact on PT or MP during maximal, voluntary concentric isokinetic muscle actions in collegiate women’s basketball players. In conjunction with previous studies, these findings suggested that trained athletes may be less susceptible to the stretching-induced force deficit than untrained, nonathletes.
APOE related alterations in cerebral activation even at college age

Background: Associations between the APOE genotype and various medical conditions have been documented at a very young age. The association between the APOE genotype and cognitive performance varies at different ages. APOE related changes in brain activation have been recently reported for middle aged and elderly subjects. Objective: To explore APOE related alterations during cognitive activation in a population of young adults. Methods: Using H215O positron emission tomography (PET), imaging was carried out in 20 healthy young adults (age 19 to 28 years; four ε4 carriers and 16 non-ε4 carriers) during a non-verbal memory task. Voxel-wise multiple regression analyses were undertaken, with the activation difference PET counts as the dependent variable and the APOE genotype as the independent variable. Results: Brain regions were identified where ε4 carriers showed significantly lower or higher activation than non-carriers. Conclusions: The results suggest that APOE dependent modulation of cerebral flow may be present even at a young age. This may reflect an APOE related physiological heterogeneity which may or may not predispose to brain disease in the ensuing decades or, less likely, the effect of very early Alzheimer’s disease related pathological changes.
Temperature dependence of evolutionary diversification: differences between two contrasting model taxa support the metabolic theory of ecology

Biodiversity patterns are largely determined by variation of diversification rates across clades and geographic regions. Although there are multiple reasons for this variation, it has been hypothesized that metabolic rate is the crucial driver of diversification of evolutionary lineages. According to the metabolic theory of ecology (MTE), metabolic rate – and consequently speciation – is driven mainly by body size and environmental temperature. As environmental temperature affects metabolic rate in ecto‐ and endotherms differently, its impact on diversification rate should also differ between the two types of organisms. Employing two independent approaches, we analysed correlates of speciation rates and, ultimately, net diversification rates for two contrasting taxa: plethodontid salamanders and carnivoran mammals. Whereas in the ectothermic plethodontids speciation rates positively correlated with environmental temperature, in the endothermic carnivorans a reverse, negative correlation was detected. These findings comply with predictions of the MTE and suggest that similar geographic patterns of biodiversity across taxa (e.g. ecto‐ and endotherms) might have been generated by different ecological and evolutionary processes.
Toward a new psychology of women

In this revised second edition, Dr Jean Baker Miller expands on her reflections on women and their future in the world. In particular, she supplies a commentary on the developments and changes experienced by women in recent years. At the centre of her argument is the understanding that the qualities women possess in abundance - tenderness, co-operativeness, ability to nurture - have been consistently devalued by both women and men. In fact, these qualities are sources of enormous strength and must be used as such. Dr Miller goes on to specify the steps women can take to realize these assets and change their lives.
Reference database of hematological parameters for growing and aging rats

Abstract The normal hematological values in various phases of the rat life provide a valuable guide to researchers and could be useful for experimental works. However, database information available on the literature are incomplete. Aim: This study aimed to present normal hematological parameters of young and aged rats. Methods: Male and female rats were distributed into seven experimental groups with 1, 2, 3, 6, 12, 18, and 24 months of age. Blood samples taken from the tails were analyzed. Normal hematological values were determined for each age group. Results: Rats showed a progressive weight gain with advancing age, predominantly after 3 months of life. With advancing age, differences were found on hematological parameters: some of them showed a progressive rise with age and others did not. Hemoglobin levels and hematocrit did not change while the number of circulating red blood cells suffered slight increase. Conclusion: The present study determined the normal values for absolute and relative hematological parameters in Wistar rats from 2 to 24 months for male and female rats. The results can be used in studies of effects of aging, feeding, and medications on growing and aging rats.
Microlensing Detections of Moons of Exoplanets

We investigate the characteristic of microlensing signals of Earth-like moons orbiting ice-giant planets. From this, we find that nonnegligible satellite signals occur when the planet-moon separation is similar to or greater than the Einstein radius of the planet. We find that the satellite signal does not diminish with the increase of the planet-moon separation beyond the Einstein radius of the planet unlike the planetary signal which vanishes when the planet is located well beyond the Einstein radius of the star. We also find that the satellite signal tends to have the same sign as that of the planetary signal. These tendencies are caused by the lensing effect of the star on the moon in addition to the effect of the planet. We determine the range of satellite separations where the microlensing technique is optimized for the detections of moons. By setting an upper limit as the angle-average of the projected Hill radius and a lower limit as the half of the Einstein radius of the planet, we find that the microlensing method would be sensitive to moons with projected separations from the planet of 0.05 AU ≲ dp≲ 0.24 AU for a Jupiter-mass planet, 0.03 AU ≲ dp≲ 0.17 AU for a Saturn-mass planet, and 0.01 AU ≲ dp≲ 0.08 AU for a Uranus-mass planet. We compare the characteristics of the moons to be detected by the microlensing and transit techniques.
Individual Learner Differences in CALL: The Field Independence/Dependence (FID) Construct

In Spring semester 2006, we conducted a study with 50 learners of German to investigate the use of a new measure (Cardenas-Claros, 2005) for research on the field independent/dependent (FID) cognitive style and CALL use. After the measure was administered, students worked on a CALL program for German that logs interaction. This paper reports the reliability and item analysis of the FID-CALL measure in addition to its relationship with learners' behaviors in the CALL program. With the goal of understanding how FID intersects with satisfaction and success in learning through CALL, we suggest areas for future development of the measure.
Is It a Fallacy to Believe in the Hot Hand in the NBA Three-Point Contest?

The NBA Three-Point Contest has been considered an ideal setting to study the hot hand, as it showcases the elite professional shooters that hot hand beliefs are typically directed towards, but in an environment that eliminates many of the confounds present in game action. We collect 29 years of NBA Three-Point Contest television broadcast data (1986-2015), apply a statistical approach that improves on those of previous studies, and find considerable evidence of hot hand shooting in and across individuals. Our results support fans' and experts' widely held belief in the hot hand among NBA shooters.
TiO2 nanotube platforms for smart drug delivery: a review

Titania nanotube (TNT) arrays are recognized as promising materials for localized drug delivery implants because of their excellent properties and facile preparation process. This review highlights the concept of localized drug delivery systems based on TNTs, considering their outstanding biocompatibility in a series of ex vivo and in vivo studies. Considering the safety of TNT implants in the host body, studies of the biocompatibility present significant importance for the clinical application of TNT implants. Toward smart TNT platforms for sustainable drug delivery, several advanced approaches were presented in this review, including controlled release triggered by temperature, light, radiofrequency magnetism, and ultrasonic stimulation. Moreover, TNT implants used in medical therapy have been demonstrated by various examples including dentistry, orthopedic implants, cardiovascular stents, and so on. Finally, a future perspective of TNTs for clinical applications is provided.
Kinematic determinants of human locomotion.

1. The aim of this study was to find kinematic patterns that are invariant across the normal range of locomotion speeds. Subjects walked at different, freely chosen speeds ranging from 0.9 to 2.1 m s‐1, while motion and ground reaction forces on the right side of the body were recorded in three‐dimensional space. 2. The time course of the anatomical angles of flexion‐extension at the hip and ankle was variable not only across subjects, but even from trial to trial in the same subject. By contrast, the time course of the changes in the angles of elevation of each limb segment (pelvis, thigh, shank and foot) relative to the vertical was stereotyped across subjects. 3. To compare the waveforms across speeds, data were scaled in time relative to gait cycle duration. The pattern of ground reaction forces was highly speed dependent. Several distinct families of curves could be recognized in the flexion‐extension angles at the hip and ankle. Instead, the waveforms of global length and elevation of the limb, elevation angles of all limb segments and flexion‐extension at the knee were invariant with speed. 4. When gait trajectories at all speeds are plotted in the position space defined by the elevation angles of the limb segments, they describe regular loops on a plane. The statistical characteristics of these angular covariations were quantified by means of principal component analysis. The first two principal components accounted together for > 99% of the total experimental variance, and were quantitatively comparable in all subjects. 5. This constraint of planar covariation of the elevation angles is closely reminiscent of that previously described for the control of posture. The existence of laws of intersegmental co‐ordination, common to the control of posture and locomotion, presumably assures the maintenance of dynamic equilibrium during forward progression, and the anticipatory adaptation to potentially destabilizing factors by means of co‐ordinated kinematic synergies of the whole body.
Source coding and transmission under common knowledge constraints

This work studies problems of source coding under the requirement that the encoder can produce an exact copy of the compressed source constructed by the decoder. This requirement, termed here as a common knowledge constraint, is satisfied automatically in rate-distortion theory for single sources. However, in the common formulation of problems of lossy source coding with side information at the decoder (the Wyner-Ziv problem), distributed source coding, and joint source-channel coding for networks, the destination can exploit the information it receives in a manner that cannot be exactly reproduced at the sender side. Some applications, like the transmission of sensitive medical information, may require that both sides - the sender and the receiver - will share a common version of the compressed data, for the purpose of future discussions or consulting. The purpose of this work is to study the implications of common knowledge constraints on the achievable rates in scenarios of lossy source coding. A single letter characterization of the rate distortion function is developed, for the problem of source coding with side information at the decoder, under a common knowledge constraint. Implications of this constraint on problems of joint source channel coding for the degraded broadcast channel are studied. Specifically, it is shown that in this setup, a scheme based on separation achieves optimal distortions.
Influence of heat stress on exercise-induced changes in regional blood flow in sheep.

Radioactive microspheres were used to measure cardiac output and blood flow to most major tissues in sheep at rest and during treadmill exercise (3- to 6-fold increase in metabolic rate for 30 min) in thermoneutral (TN) [dry bulb temperature (Tdb) = 16 degrees C, wet bulb temperature (Twb) = 12 degrees C] and mildly hot (MH) (Tdb = 40 degrees C, Twb = 23 degrees C) environments. During exercise, rectal temperature increased more under MH than under TN conditions; exercise-induced changes in the major central cardiovascular parameters were unaffected by MH. Exercise in TN caused mild hypocapnia, and in MH, severe respiratory alkalosis. Skin blood flow in the torso decreased during exercise in TN and MH. Extremity skin blood flow was increased by heat but not exercise. Exercise-induced increases in flows to respiratory muscles and upper respiratory tract tissues were greatly enhanced in MH. Exercise caused large increases in blood flow to fore- and hindlimb muscles, which were less in MH than in TN. Effects of MH on exercise-induced changes in flow to these and other tissues (e.g., abdominal viscera and adipose tissue) are discussed in terms of the conflicting requirements of energy expenditure and body temperature regulation during exercise in sheep and other species, particularly humans.
Mapping of Chikungunya Virus Interactions with Host Proteins Identified nsP2 as a Highly Connected Viral Component

ABSTRACT Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus that has been responsible for an epidemic outbreak of unprecedented magnitude in recent years. Since then, significant efforts have been made to better understand the biology of this virus, but we still have poor knowledge of CHIKV interactions with host cell components at the molecular level. Here we describe the extensive use of high-throughput yeast two-hybrid (HT-Y2H) assays to characterize interactions between CHIKV and human proteins. A total of 22 high-confidence interactions, which essentially involved the viral nonstructural protein nsP2, were identified and further validated in protein complementation assay (PCA). These results were integrated to a larger network obtained by extensive mining of the literature for reports on alphavirus-host interactions. To investigate the role of cellular proteins interacting with nsP2, gene silencing experiments were performed in cells infected by a recombinant CHIKV expressing Renilla luciferase as a reporter. Collected data showed that heterogeneous nuclear ribonucleoprotein K (hnRNP-K) and ubiquilin 4 (UBQLN4) participate in CHIKV replication in vitro. In addition, we showed that CHIKV nsP2 induces a cellular shutoff, as previously reported for other Old World alphaviruses, and determined that among binding partners identified by yeast two-hybrid methods, the tetratricopeptide repeat protein 7B (TTC7B) plays a significant role in this activity. Altogether, this report provides the first interaction map between CHIKV and human proteins and describes new host cell proteins involved in the replication cycle of this virus.
