User Set Estimation for Adaptive Resource Allocation in a Multiuser-OFDM System

In the multiuser OFDM system, various adaptive subcarrier-bit-and-power allocation algorithms have been investigated based on the assumption that the number of supportable users is given. This paper proposes a supportable user set estimation in order to adopt those allocation algorithms in the multiuser-OFDM system. The number of supportable users is estimated in an iterative way by calculating the required power approximately and comparing it with an available power after determining the number of subcarriers to be allocated. Simulation results show that the proposed user set estimation provides a significant complexity reduction for the adaptive subcarrier-bit-and-power allocation in the multiuser-OFDM system.
The meaning of death in Kenkō Yoshida's Tsurezuregusa [Essays in idleness]

Abstract This article discusses the meaning of death in Kenkō Yoshida's Tsurezuregusa [Essays in idleness], completed around 1330 at the end of the Kamakura Period (1185–1333). Kenkō, who was a Buddhist monk and hermit, naturally construed the concept of death in terms of the impermanence of the world. Taking Lakoffian conceptual metaphor theory, in which death is understood as an abstract category, as a jumping-off point, I contrast the Buddhist conception of death with different conceptualizations of metaphor and metonymy by contemporary scholars to locate the notion of “death” in the medieval linguistic context. I claim that while death in Essays in idleness is more frequently considered non-literal, it is not interpretable metaphorically. This hints at an alternative, namely, that Kenkō's concept of death is created metonymically. Impermanence as a literary aesthetic thus crystallizes in the form of death as a syntagmatic metonym.
Learning features on tear film lipid layer classification

Dry eye is a prevalent disease which leads to irritation of the ocular surface, and is associated with symptoms of discomfort and dryness. The Guillon tear film classification system is one of the most common procedures to diagnose this disease. Previous research has demonstrated that this classification can be automatized by means of image processing and machine learning techniques. However, all approaches for automatic classification have been focused on dark eyes, since they are most common in humans. This paper introduces a methodology making use of feature selection methods, to learn which features are the most relevant for each type of eyes and, thus, improving the automatic classification of the tear film lipid layer independently of the color of the eyes. Experimental results showed the adequacy of the proposed methodology, achieving classification rates over 90%, while producing unbiased results and working in real-time.
PLACENTAL TRANFER OF NITROFURANTOIN AND FURALTADONE.

The placental transfer of nitrofurantoin and furaltadone was determined in the guinea pig, rabbit, dog, and sheep. Both compounds entered the fetal circulation of the dog to a greater extent than in the other species, and furaltadone consistently crossed the placenta more readily than nitrofurantoin in all species. On the basis of these results, it is suggested that the transplacental movement of drugs is determined by both the physical characteristics of the drug and the morphohistologic structure of the placenta.
Can Ockham's Razor Cut Through the Mind-Body Problem? A Critical Analysis of the Raze Dualism Argument for Materialism.

Notes that the question of materialism's adequacy as a solution to the mind-body problem is important in psychology as fields supported by eliminative materialism (e.g. neuropsychology and sociobiology) aim to cannibalize psychology (E. O. Wilson, 1999). A common argument for adopting a materialistic worldview, termed the Raze Dualism argument in reference to Ockham's razor, is based on the principle of parsimony. It states that materialism is to be considered the superior solution to the mind-body problem because it is simpler than the dualist alternative. In this paper, a prominent version of this argument (P. Churchland, 1988) is critiqued via an analysis of each of its premises. Illustrative in general of the limitations of materialism, this argument is undermined by assumptions which do not withstand scrutiny. First, Ockham's razor is shown to be a problematic principle. Second, the question of empirical superiority or equality is unresolved. Finally, there are other alternatives to materialism that are equally parsimonious, such as idealism. The result of the argument is to reopen the case for idealism and dualism and to force the issue to be determined on other grounds.
Tetraaquabis(3,5-di-4-pyridyl-1,2,4-triazolato-κN)cobalt(II) dihydrate

The CoII atom in the title compound, [Co(C12H8N5)2(H2O)4]·2H2O, lies on a center of inversion and is bonded to two N-heterocycles and to four water molecules in a slightly distorted octahedral coordination. The coordinated and lattice water molecules interact with the N-heterocycles through O—H⋯N hydrogen bonds, generating a three-dimensional supramolecular architecture.
Identical FBG-Based Quasi-Distributed Sensing by Monitoring the Microwave Responses

We present a quasi-distributed fiber sensing technique by monitoring the microwave responses through the reflections of the fiber Bragg gratings (FBGs). These FBGs are all identically and specially fabricated with the low reflectivity and the broad reflection bandwidth. The microwave signals are used to resolve the positions and the reflected intensities from FBGs along the optical fiber. The reflected intensity of each FBG can be modulated through the wavelength shift induced by the sensing parameter, since the optical bandpass filter with the matched spectrum is adopted in the detection. The relative amplitude change (RAC) of the microwave responses are determined by the change of reflected intensities from FBGs. We demonstrate a proof-of-concept experiment for the strain sensing using six identical FBGs. The experimental measurements show that a high-strain sensing sensitivity of 0.0452% RAC/με is achieved within the measured range of 2000με. The sensing positions also can be accurately located from the demodulation figure through invert-fast Fourier transform algorithm with the locating resolution of ~10.2 cm.
Hearing and balance disorders: a new approach.

hidden handicaps with significant public health and socioeconomic consequences, in addition to a marked personal impact on the quality of life. The recent House of Commons Health Committee report, Audiology services: fifth report of session 2006–7, highlighted that hearing and balance services have not been seen as a priority and that primary care trusts have failed to give them the attention they deserve.1 The need for improved services has also been stressed by both the voluntary sector:
Hyperglycemic stress response in Crustacea

Blood glucose level in crustaceans is controlled by the crustacean Hyperglycemic Hormone (cHH),released from the eyestalk neuroendocrine centres both under physiological and environmental stressconditions. Hyperglycemia is a typical response of many aquatic animals to pollutants and stress and,in crustaceans, increased circulating cHH and hyperglycemia are reported to result from exposure toseveral environmental stressors. Biogenic amines and enkephalin have been found to mediate therelease of several neurohormones from crustacean neuroendocrine tissue and a model of thecontrolling network is proposed.
Modélisation des dynamiques de maladies foliaires de cultures pérennes tropicales à différentes échelles spatiales : cas de la cercosporiose noire du bananier

Cette these concerne la modelisation des dynamiques de maladies foliaires de cultures perennes tropicales a differentes echelles spatiales. Cette approche de modelisation est appliquee a la cercosporiose noire du bananier. Il s'agit d'explorer et de determiner les parametres environnementaux et de resistance de l'hote ayant une influence significative sur la dynamique spatio-temporelle de la maladie et d'apporter des elements associes au controle de la cercosporiose noire. Deux modeles ont ete developpes dans le cadre de cette these. La dynamique epidemiologique au niveau de la plante est decrite par un modele mecaniste decompose en un module de croissance de la plante et un module epidemiologique decrivant le cycle epidemique du pathogene. Le modele a ete valide par un jeu de donnees independant. Les experimentations numeriques et l'analyse de sensibilite du modele realisees par les methodes de Morris et de e-FAST ont permis de mieux comprendre le fonctionnement epidemique de cette maladie et d'identifier les parametres influant le plus la dynamique epidemique en particulier la vitesse d'extension des lesions, la duree d'incubation et l'efficacite d'infection. L'approche bayesienne a permis d'affiner l'information a priori disponible pour ces trois parametres. L'analyse de sensibilite du modele a egalement permis d'identifier l'influence de deux parametres lies a la croissance de la plante : le nombre de feuilles presentes sur une plante et le rythme d'emission foliaire. Un modele de dynamique spatio-temporelle de la cercosporiose noire a ete developpe a l'echelle d'un territoire a partir d'enquetes effectuees en Martinique (FWI) pendant la periode d'invasion de cette maladie de septembre 2010 a mai 2012. Le modele utilise la theorie de processus ponctuels pour decrire la dynamique de la maladie. Les donnees recoltees etant censurees, l'inference des parametres du modele a ete realisee dans un cadre bayesien en utilisant un algorithme MCMC d'augmentation de donnees. Les resultats mettent en evidence l'impact des jardins prives et des parcelles de bananiers plantains dans la dynamique invasive de la cercosporiose noire. Le modele et l'inference developpes permettent de reconstruire la dynamique spatio-temporelle de l'invasion en fonction de la couverture du paysage. Les deux modeles de dynamiques spatio-temporelles developpes a deux echelles spatiales differentes ont permis d'acquerir des informations importantes pour construire des outils de conception de methode de controle de la cercosporiose noire des bananiers.
Variations in State Laws Governing School Reintegration Following Concussion

OBJECTIVE: We sought to examine the prevalence, scope, and specificity of provisions governing school reintegration in current state concussion laws. METHODS: State concussion laws as of May 2016 were independently assessed and classified by 2 trained coders. Statutes were classified as “Return-to-Learn” (RTL) laws if they contained language mandating institutional action at the state, district, or school level related to academic reintegration of youth who have sustained a concussion. All statutes classified as RTL laws were further analyzed to determine scope, required actions, and delineation of responsibility. RESULTS: RTL laws were uncommon, present in only 8 states. Most (75%) of these laws held schools responsible for RTL management but mandated RTL education for school personnel was less frequent, present in only one-quarter of the laws. None of the RTL laws provided guidance on support of students with persistent postconcussive symptoms, and only 1 recommended an evidence-based standard for RTL guidelines. CONCLUSIONS: Our review of state concussion laws indicates scant and vague legal guidance regarding RTL. These findings suggest an opportunity for legislative action on the issue of RTL, and reveal the need for better integration of laws and research, so that laws reflect existing best-practice recommendations and remain current as the evidence base develops.
Design of Small Antennas for Mobile Handsets Using Magneto-Dielectric Material

This communication presents practical implementations of small antennas using magneto-dielectric (MD) materials. We first describe the manufacturing process of MD materials with a low-loss property (tan δm <; 0.1) up to 2 GHz. With this MD material as a substrate, miniaturized handset antennas are developed and the radiation performances are compared with the dielectric substrate antenna. The measured results show that the required volume of MD chip antenna is minimized to 25 mm × 5 mm × 3 mm at cellular frequency and the bandwidth is better compared to dielectric chip antennas. In addition, MD loaded antenna is designed to improve the performance of conventional antennas on the plastic carriers.
Science Driven Innovations Powering Mobile Product: Cloud AI vs. Device AI Solutions on Smart Device

Recent years have witnessed the increasing popularity of mobile devices (such as iphone) due to the convenience that it brings to human lives. On one hand, rich user profiling and behavior data (including per-app level, app-interaction level and system-interaction level) from heterogeneous information sources make it possible to provide much better services (such as recommendation, advertisement targeting) to customers, which further drives revenue from understanding users' behaviors and improving user' engagement. In order to delight the customers, intelligent personal assistants (such as Amazon Alexa, Google Home and Google Now) are highly desirable to provide real-time audio, video and image recognition, natural language understanding, comfortable user interaction interface, satisfactory recommendation and effective advertisement targeting. This paper presents the research efforts we have conducted on mobile devices which aim to provide much smarter and more convenient services by leveraging statistics and big data science, machine learning and deep learning, user modeling and marketing techniques to bring in significant user growth and user engagement and satisfactions (and happiness) on mobile devices. The developed new features are built at either cloud side or device side, harmonically working together to enhance the current service with the purpose of increasing users' happiness. We illustrate how we design these new features from system and algorithm perspective using different case studies, through which one can easily understand how science driven innovations help to provide much better service in technology and bring more revenue liftup in business. In the meantime, these research efforts have clear scientific contributions and published in top venues, which are playing more and more important roles for mobile AI products.
Human fetal heart rate variability-characteristics of autonomic regulation in the third trimester of gestation

Abstract Aim: To describe developmental aspects of the sympatho-vagal heart rate regulation in the human fetus by applying numerics to visual descriptions of fetal heart rate patterns throughout the third trimester of pregnancy. The focus is to determine potential benefits of this alternative means of assessing the maturation of the fetal autonomic nervous system by analysis of fetal heart rate variability (fHRV). Subjects and methods: The magnetocardiograms of 103 normal fetuses between 24+1 and 41+6 weeks of gestation were studied. Fetal heart beat intervals were determined with a temporal precision of 1 ms. The levels of fetal activity were estimated according to characteristic heart rate patterns (I–III) prior to 32, between 32–35 and beyond 35 (groups 1–3) completed weeks. Mean heart rate (mHR), standard deviation of normal-to-normal beat intervals (SDNN) and root mean square of successive differences of normal beats (RMSSD) served as fHRV indices, mean permutation entropy (PE_Mean) as complexity measure. SDNN/RMSSD was introduced as a potential marker for sympatho-vagal balance. Results: Low activity fHRP (I) were characterized by significantly lower level fHRV indices and higher PE_Mean when compared to fHRP II. We found that SDNN/RMSSD decreases with gestation in fHRP I, which suggests increasing vagal influence. In fHRP III (assigned to active awake fetuses only after 32 weeks), highest level SDNN and mHR are associated with a dramatically reduced complexity. fHRV indices cluster characteristically with the activity levels. Conclusions: We conclude that a combined analysis of fHRV, based on SDNN/RMSSD and PE_Mean, and fHRP is advantageous in the assessment of maturation of the fetal autonomic nervous system.
Association between visceral fat, IL-8 and endometrial cancer.

BACKGROUND/AIM In endometrial cancer, visceral obesity, as a risk factor, is associated with a chronic inflammatory process, confirmed by the elevation of serum inflammatory markers in obese patients. The aim of the present study was to evaluate the correlation between visceral fat, assessed by ultrasonography, and the systemic levels of interleukin (IL)-8 in patients with endometrial cancer. This study also evaluated the usefulness of abdominal ultrasonography in assessing the visceral fat correlated with systemic inflammatory status, as an alternative method to identify patients at risk of endometrial cancer. MATERIALS AND METHODS The study was a case-control analysis including two groups of patients: Group I: 44 patients diagnosed with endometrial cancer; group II: 44 patients with no gynecological pathology. The diagnosis of endometrial cancer was performed following histopathological examination that evaluated the tissue material obtained through endometrial biopsy. These patients underwent ultrasound examination by which intraperitoneal fat was determined. IL-8 levels were determined for each patient. The Student's t-test was used for the comparison of the means and the Mann-Whitney test for rank comparison of two independent samples. RESULTS In patients diagnosed with endometrial cancer, the visceral fat area evaluated by ultrasound was significantly larger (p<0.0001) compared to that of the control group. The plasma levels of IL-8 in the endometrial cancer group were significantly elevated (p<0.001) compared to the control group. A positive linear correlation was also found between the visceral fat area and plasma levels of IL-8. CONCLUSION The plasma levels of IL-8 are positively linearly correlated with visceral fat. Determination of visceral fat in association with IL-8 levels may be a predictive factor for endometrial cancer.
Prefrontal Cortical GABAergic Dysfunction Contributes to Age-Related Working Memory Impairment

Working memory functions supported by the prefrontal cortex decline in normal aging. Disruption of corticolimbic GABAergic inhibitory circuits can impair working memory in young subjects; however, relatively little is known regarding how aging impacts prefrontal cortical GABAergic signaling and whether such changes contribute to cognitive deficits. The current study used a rat model to evaluate the effects of aging on expression of prefrontal GABAergic synaptic proteins in relation to working memory decline, and to test whether pharmacological manipulations of prefrontal GABAergic signaling can improve working memory abilities in aged subjects. Results indicate that in aged medial prefrontal cortex (mPFC), expression of the vesicular GABA transporter VGAT was unchanged; however, there was a significant increase in expression of the GABA synthesizing enzyme GAD67, and a significant decrease in the primary neuronal GABA transporter GAT-1 and in both subunits of the GABA(B) receptor (GABA(B)R). Expression of VGAT, GAD67, and GAT-1 was not associated with working memory ability. In contrast, among aged rats, GABA(B)R expression was significantly and negatively associated with working memory performance, such that lower GABA(B)R expression predicted better working memory. Subsequent experiments showed that systemic administration of a GABA(B)R antagonist, CGP55845, dose-dependently enhanced working memory in aged rats. This enhancing effect of systemic CGP55845 was reproduced by direct intra-mPFC administration. Together, these data suggest that age-related dysregulation of GABAergic signaling in prefrontal cortex may play a causal role in impaired working memory and that targeting GABA(B)Rs may provide therapeutic benefit for age-related impairments in executive functions.
The two power limits conditioning step frequency in human running.

1. At high running speeds, the step frequency becomes lower than the apparent natural frequency of the body's bouncing system. This is due to a relative increase of the vertical component of the muscular push and requires a greater power to maintain the motion of the centre of gravity, Wext. However, the reduction of the step frequency leads to a decrease of the power to accelerate the limbs relatively to the centre of gravity, Wint, and, possibly, of the total power Wtot = Wext + Wint. 2. In this study we measured Wext using a force platform, Wint by motion picture analysis, and calculated Wtot during human running at six given speeds (from 5 to 21 km h‐1) maintained with different step frequencies dictated by a metronome. The power was calculated by dividing the positive work done at each step by the duration of the step (step‐average power) and by the duration of the positive work phase (push‐average power). 3. Also in running, as in walking, a change of the step frequency at a given speed has opposite effects on Wext, which decreases with increasing step frequency, and Wint, which increases with frequency; in addition, a step frequency exists at which Wtot reaches a minimum. However, the frequency for a minimum of Wtot decreases with speed in running, whereas it increases with speed in walking. This is true for both the step‐average and the push‐average powers. 4. The frequency minimizing the step‐average power equals the freely chosen step frequency at about 13 km h‐1: it is higher at lower speeds and lower at higher speeds. The frequency minimizing the push‐average power approaches the freely chosen step frequency at high speeds (around 22 km h‐1 for our subjects). 5. It is concluded that the increase of the vertical push does reduce the step‐average power, but that a limit is set by the increase of the push‐average power. Between 13 and 22 km h‐1 the freely chosen step frequency is intermediate between a frequency minimizing the step‐average power, eventually limited by the maximum oxygen intake (aerobic power), and a frequency minimizing the push‐average power, set free by the muscle immediately during contraction (anaerobic power). The first need prevails at the lower speed, the second at the higher speed.
Executive Functions in Students With Depression, Anxiety, and Stress Symptoms

Introduction: This study aimed to investigate and compare the executive functions of students with depression, anxiety, and stress symptoms with those functions in healthy ones. Methods: This study was a comparative and non-clinical analysis. The study population comprised all students of Shahid Beheshti University, Tehran, Iran. A total of 448 students were recruited using convenience sampling method. They were also screened using the Depression Anxiety Stress Scales (DASS) test comprising 21 items. Of study participants, 30 people were depressed, 27 had anxiety, and 15 suffered from stress. Then, 50 control people were matched with them. Next, both groups were compared using the Stroop test, Wisconsin card sorting, and cognitive ability test. Results: Using MANOVA test, data analysis revealed no significant differences among 4 groups with regard to selective attention and shifting attention. Depressed group reacted rapidly as opposed to the anxiety group with regard to measures of shifting attention and cognitive abilities; it was observed that the memory, inhibition control, planning, and flexibility of the healthy group were better than those of the 3 other groups. Conclusion: The findings of this research raised specific issues in relation to the role of depression, anxiety, and stress in the disruption of the executive functions of sufferers. Selective and shifting attention and cognitive abilities are specifically affected in this regard. Meanwhile, the role of stress in impairing decision making and the major role of anxiety in impairing sustained attention was shown to be considerable.
