MIGRAINE AND TENSION-TYPE HEADACHE IN SCHOOLCHILDREN IN WESTERN OF TURKEY

This study aims to elucidate the effects of BMI (Body Mass Index), age, gender, personality traits, sleep problems, family history of headache, and hobbies on primary headaches in school children in Mugla. The study also intends to discuss the association of headaches with the courses and tests using monthly follow-up forms. A cross-sectional school-based study was performed on 511 school children (aged 8-15) between January and May 2012 in Mugla. Potential triggering and aggravating demographic and social variables were investigated based on a diagnosis of ICHD-II migraine. The prevalence of recurrent headache was found to be 31.7% in Mugla. Of the studied population, 17.6% had tension-type headache (TTH), 8.84% had migraine, and 5.3% had mixed headache symptoms suggesting both TTH and migraine. Headaches were found to be more common among girls. Using logistic regression analysis, we found that increasing age, increased BMI values, presence of siblings, family history of headache (especially maternal), sensitive personality traits (especially vulnerable children), and sleep problems had a statistically significant effect on headaches in children. Additionally, Mondays and particularly math test dates were found to increase the occurrence on headache in school children. In contrast, hobbies were found not to have any significant effects on headaches. As a common healthcare problem, migraine and TTH are prevalent among school children. Primary headache disorders of school children included family history of headache, personality traits, school life, increased values of BMI, sleep problems, but not hobbies in our study population. Lifestyle-coping strategies are essential for school children.
Structured Pruning for Efficient ConvNets via Incremental Regularization

Parameter pruning is a promising approach for CNN compression and acceleration by eliminating redundant model parameters with tolerable performance degrade. Despite its effectiveness, existing regularization-based parameter pruning methods usually drive weights towards zero with large and constant regularization factors, which neglects the fragility of the expressiveness of CNNs, and thus calls for a more gentle regularization scheme so that the networks can adapt during pruning. To achieve this, we propose a new and novel regularization-based pruning method, named IncReg, to incrementally assign different regularization factors to different weights based on their relative importance. Empirical analysis on CIFAR-10 dataset verifies the merits of IncReg. Further extensive experiments with popular CNNs on CIFAR-10 and ImageNet datasets show that IncReg achieves comparable to even better results compared with state-of-the-arts. Our source codes and trained models are available here: https://github.com/mingsun-tse/caffe_increg.
A solvable model for decoupling of interacting clusters

We consider M clusters of interacting particles, whose in-group interactions are arbitrary, and inter-group interactions are approximated by oscillator potentials. We show that there are masses and frequencies that decouple the in-group and inter-group degrees of freedom, which reduces the initial problem to M independent problems that describe each of the relative in-group systems. The dynamics of the M center-of-mass coordinates is described by the analytically solvable problem of M coupled harmonic oscillators. This letter derives and discusses these decoupling conditions. Furthermore, to illustrate our findings, we consider a charged impurity interacting with a ring of ions. We argue that the impurity can be used to probe the center-of-mass dynamics of the ions.
Stability of TCP/AQM Networks Based on a Switched Time-Delay System Modeling

Abstract We study the modeling and stability of TCP/AQM systems. The control-theoretic framework used in most of the previous work is linear system theory. Based on the linearization of nonlinear congestion control systems, classical linear techniques, such as the Nyquist or Bode criteria, are applied for the analysis of stability. The success of the linearization method depends on the assumption that the equilibrium is far away from the zero queue length point so that the linearization is well-defined. In this paper, the nonlinearity of the queue part is taken into consideration and TCP/AQM systems with proportional control are modeled as a class of switched time-delay systems. For such systems, we employ a Lyapunov approach and establish stability results. Simulations are presented to demonstrate the effectiveness of the stability analysis.
Growth of Soot Volume Fraction and Aggregate Size in 1D Premixed C2H4/Air Flames Studied by Laser-Induced Incandescence and Angle-Dependent Light Scattering

The growth of soot volume fraction and aggregate size was studied in burner-stabilized premixed C2H4/air flames with equivalence ratios between 2.0 and 2.35 as function of height above the burner using laser-induced incandescence (LII) to measure soot volume fractions and angle-dependent light scattering (ADLS) to measure corresponding aggregate sizes. Flame temperatures were varied at fixed equivalence ratio by changing the exit velocity of the unburned gas mixture. Temperatures were measured using spontaneous Raman scattering in flames with equivalence ratios up to ϕ = 2.1, with results showing good correspondence (within 50 K) with temperatures calculated using the San Diego mechanism. Both the soot volume fraction and radius of gyration strongly increase in richer flames. Furthermore, both show a nonmonotonic dependence on flame temperature, with a maximum occurring at ~1675 K for the volume fraction and ~1700 K for the radius of gyration. The measurement results were compared with calculations using two different semiempirical two-equation models of soot formation. Numerical calculations using both mechanisms substantially overpredict the measured soot volume fractions, although the models do better in richer flames. The model accounting for particle coagulation overpredicts the measured radii of gyration substantially for all equivalence ratios, although the calculated values improve at ϕ = 2.35.
Quantifying the relative contributions of riparian and hillslope zones to catchment runoff

The spatial and temporal sources of headwater catchment runoff are poorly understood. We quantified the contributions of hillslopes and riparian zones to streamflow for two storm events in a highly responsive, steep, wet watershed located on the west coast of the South Island of New Zealand. We examined the spatial and temporal components of catchment storm flow using a simple continuity‐based approach. We tested this with independent isotopic/solute mass balance hydrograph separation techniques. We monitored catchment runoff, internal hydrological response, isotopic, and solute dynamics at a trenched hillslope, and at hillslope and riparian positions in a 2.6‐ha catchment. The gauged hillslope was used to isolate and quantify (by difference) riparian and hillslope zone contributions to the 2.6‐ha headwater catchment. Utilizing flow‐based approaches and a tracer‐based mass balance mixing model, we found that hillslope runoff comprised 2–16% of total catchment storm runoff during a small 27‐mm event and 47–55% during a larger 70‐mm event. However, less than 4% of the new water collected at the catchment outlet originated from the hillslopes during each event. We found that in the 27‐mm rain event, 84–97% of total storm runoff was generated in the riparian zone. In a larger 70‐mm event, riparian water dominated total flow early in the event, although the hillslope became the main contributor once hillslope runoff was initiated. Despite the large amount of subsurface hillslope runoff in total storm runoff during the second larger event, riparian and channel zones accounted for 96% of the new water measured at the catchment outlet. Riparian water dominated between events, throughout small runoff events, and during early portions of large events. While this sequencing of catchment position contributions to flow has been conceptualized for some time, this is the first study to quantify this timing, constrained by hydrometric, isotopic, and solute approaches.
Secondary pollen presentation and style morphology in the invasive weed Mikania micrantha in South China.

Mikania micrantha H.B. K. is a successful invasive weed in many parts of the world. Its reproductive biology, specifically, floral functional morphology, growth and behavior of the style during anthesis, and style morphology, was studied in an open M. micrantha population in South China during the flowering seasons of 2004 and 2005. Floral biology was studied in detail by examining florets at different developmental stages under a dissecting microscope and a scanning electron microscope. Stigma receptivity and pollen viability was determined by MTT [3-(4,5-dimethylthiazol-yl)-2,5-diphenyl-2H-tetrazolium bromide] staining technique. The results show that M. micrantha is protandrous and has a secondary pollen presentation system which characterizes the family Asteraceae. Typically, the flowering period is 6 days and can be divided into six floral stages (A, B, C, D, E and F) based on style morphology and behaviour. At the beginning of anthesis, the style bends to break and enter the tube formed by five fused anthers. Later, the style protrudes the anther tube and moves the pollen out from the anther. During anthesis, two partially overlapping phases, functionally male phase and functionally female phase, can be distinguished by MTT tests: the former is from stage B to D, and the latter is stage E. The style has two style branches in its terminal part. The sweeping hairs, which act as pollen presenter, are located on the tips and on the upper parts of the style branches forming developed stylar appendages. The stigmatic papillae are separated into two ventro-marginal bands along each style branch in symmetric arrangement. The bending behavior of the style and the sweeping hairs play an important role in presenting pollen to pollinator.
Multiwavelength observations of the Type IIb supernova 2009mg

We present Swift UVOT and XRT observations, and visual wavelength spectroscopy of the Type IIb supernova (SN) 2009mg, discovered in the Sb galaxy ESO 121-G26. The observational properties of SN 2009mg are compared to the prototype Type IIb SNe 1993J and 2008ax, with which we find many similarities. However, minor differences are discernible including SN 2009mg not exhibiting an initial fast decline or u-band upturn as observed in the comparison objects, and its rise to maximum is somewhat slower leading to slightly broader light curves. The late-time temporal index of SN 2009mg, determined from 40 days post-explosion, is consistent with the decay rate of SN 1993J, but inconsistent with the decay of 56 Co. This suggests leakage of -rays out of the ejecta and a stellar mass on the small side of the mass distribution. Our XRT nondetection provides an upper limit on the mass-loss rate of the progenitor of u M < 1.5 × 10 −5 M⊙ yr −1 . Modelling of the SN light curve indicates a kinetic energy of 0.15 +0.02 −0.13×10 51 erg, an ejecta mass of 0.56
Effect of Classical music on heart rate variability between genders

Background: Listening to music alleviates stress but the gender specific difference in the beneficial response elicited by the music on autonomic function is not clear. Therefore this study has been undertaken to look for the significant difference in the autonomic modulation between males and females on listening to a classical music, Rag Bilahari.Aims& Objectives: To assess the effect of music on autonomic modulation between genders.Materials and methods: 60 medical students between the age of 17 and 20 years were divided into study group of 30 students who were to be exposed to classical music and 30 for controls who were not exposed to music. Each group had 15 participants from each gender. The study group was exposed to the preselected music for half an hour for 30 days and 5 min HRV was recorded before and after the intervention, using PHYSIOPAC- PP4 software (MEDICAID SYSTEMS, Chandigarh) for all the participants of both the groups and the basal cardiovascular parameters of heart rate, blood pressure and the time domain parameters of HRV such as mean RR interval, standard deviation of all normal RR intervals (SDNN), root mean square of differences between adjacent normal RR intervals (RMSSD), and the percentage of adjacent RR intervals with a difference of duration greater than 50 msec (PNN50) were analysed using Kubios analyser.Results: Significant difference in heart rate being lower in females (p=0.0006) and mean RR interval being higher in females (P=0.0004) was observed in music group while parasympathetic activity was increased in both genders.Conclusion: Music listening enhances parasympathetic activity which is more pronounced in females.
The Effects of Mentoring on Staff Nurses' Job Satisfaction

THE EFFEECTS OF MENTORING ON STAFF NURSES’ JOB SATISFACTION By Karen S. Delrue The shortage of registered nurses in the nation’s healthcare organizations calls for an exploration of avenues that can impact recruitment and retention. The practice of mentoring has demonstrated a positive impact on job satisfaction in previous studies. The purpose of this study was to determine if RNs would identify having mentors in their professional careers and to examine differences in levels of job satisfaction compared to those without a mentor. This study also explored whether or not the perceived quality of the mentor affected job satisfaction. Data were collected through the use of standardized questionnaires from a probability sample of 97 RNs. Approximately half of the participants identified having a mentor. Although the mentored group demonstrated higher levels of job satisfaction, it was not significantly different from the non-mentored group. There was also no significant difference in job satisfaction based upon the quality of the mentor. The mentored group did attribute increased self-confidence, self-awareness, and self-actualization to their mentored experiences.
The Effects of Whole-Body Vibration Training for Rehabilitation After ACL Reconstruction: A Systematic Review

We investigated the effects of short-term WBVT program for rehabilitation after ACL reconstruction on postural control, knee position sense, and knee laxity. This review was restricted to randomized controlled trials, which investigated the rehabilitation effects of WBVT on physical function compared with conventional rehabilitation program. Data from a total of 99 participants with ACL reconstruction in 3 studies were included. Articles with high risk of bias were included based on the criteria of Cochrane Review Guideline. Furthermore, based on the International Society of Musculoskeletal and Neuronal Interactions recommendation, the lack of information on the WBV settings was found in them. Meta-analysis showed that, after WBVT intervention, no significant standardized mean difference (SMD) was observed in postural stability (n = 3; -0.58[-1.32-0.16], p = 0.13) with large heterogeneity (I2 = 67%) and knee laxity (n = 2; -0.10[-0.50-0.70], p = 0.74) with no heterogeneity (I 2 = 0%), whereas a significant SMD was observed in position sense (n = 2; SMD = -1.44[-2.22- -0.67],p = 0.0003) with large heterogeneity (I 2 = 85%). We concluded that WBVT might be a promising alternative exercise therapy for rehabilitation after ACL reconstruction. However, to clarify the effects of WBVT on prevention from re-injury after returning to sports activities, future studies with longer term WBVT with better quality are strongly
Bone Marrow Derived Extracellular Vesicles Activate Osteoclast Differentiation in Traumatic Brain Injury Induced Bone Loss

Traumatic brain injury (TBI) is a major source of worldwide morbidity and mortality. Patients suffering from TBI exhibit a higher susceptibility to bone loss and an increased rate of bone fractures; however, the underlying mechanisms remain poorly defined. Herein, we observed significantly lower bone quality and elevated levels of inflammation in bone and bone marrow niche after controlled cortical impact-induced TBI in in vivo CD-1 mice. Further, we identified dysregulated NF-κB signaling, an established mediator of osteoclast differentiation and bone loss, within the bone marrow niche of TBI mice. Ex vivo studies revealed increased osteoclast differentiation in bone marrow-derived cells from TBI mice, as compared to sham injured mice. We also found bone marrow derived extracellular vesicles (EVs) from TBI mice enhanced the colony forming ability and osteoclast differentiation efficacy and activated NF-κB signaling genes in bone marrow-derived cells. Additionally, we showed that miRNA-1224 up-regulated in bone marrow-derived EVs cargo of TBI. Taken together, we provide evidence that TBI-induced inflammatory stress on bone and the bone marrow niche may activate NF-κB leading to accelerated bone loss. Targeted inhibition of these signaling pathways may reverse TBI-induced bone loss and reduce fracture rates.
Foreign Direct Investment in a Two‐Tier Oligopoly: Coordination, Vertical Integration, and Welfare

We study foreign direct investment (FDI) by two independent investors/entrants into a two‐tiered oligopolistic industry. An FDI subsidy at a single stage of production can be sufficient to resolve the coordination problem facing investors thereby inducing entry at both stages. However, due to linkage offsetting, FDI at both stages may yield lower domestic welfare than FDI at a single stage. Vertical integration not only solves the coordination problem, it also eliminates double marginalization. But since the integrated multinational does not sell the intermediate to local firms, its entry generates no vertical linkages and can yield lower welfare than FDI by independent firms.
The Significance of Bank Capital and Liquidity on Business Cycles: Empirical Evidence from the UK Banking Sector

﻿Stable financial system and liquidity creation are fundamental to economic growth. As a result of recent financial crisis, there has been huge debate on the minimum capital level that is able to absorb credit risk especially during downturn. The Basel III capital proposals have some very useful elements, notably a leverage ratio, a capital buffer and the proposal to deal with pro-cyclicality through dynamic provisioning based on expected losses. Using 10 largest banks in the UK, with the annual data from 2004 to 2013, this research examines the link between bank capital, liquidity and business cycle. Employing both dynamic and static model which is devoid other previous work, the result shows that adequate capital level will mitigate the extent of the financial shocks. The positive association between loan to deposit and changes in the gross domestic product implies that credit extension falls as the economy contract.
On the category of certain classes of transformations in ergodic theory

The main purpose of this paper is to establish some category theorems for certain classes of "invertible measurable and nonsingular transformations" on the unit interval. We chose our setting to be that of the unit interval in order to simplify the presentation (2). The paper is divided into two parts. The first part contains the background material; here we make precise our terminology and prove some preliminary results. The main result of Part I is an approximation theorem (Theorem 1) which is used essentially in the second part of the paper, but which may be of independent interest. In Part II we prove a category theorem for the positive invertible isometries of L' (Theorem 2); from this in turn we derive our main conclusions (Theorem 3). We wish to remark here that the proofs of our theorems are straightforward and do not use, at any stage, the existence of the concrete examples constructed by D. S. Ornstein in [10] and by R. V. Chacon in [2]. From this
Impact of Positive Psychology Education and Interventions on Well-Being: A Study of Students Engaged in Pastoral Care

Positive psychology investigates human strengths and virtues and promotes well-being. Relying on this assumption, positive interventions have been continuously designed to build pleasure and happiness, joy and contentment, engagement and meaning, hope and optimism, satisfaction and gratitude, spirituality, and various other positive measures of well-being. In line with this model of positive psychology and interventions, this study investigated certain measures of well-being in a group of 45 students enrolled in an 18week positive psychology course and simultaneously engaged in service-oriented interventions that they chose for themselves based on the course content and individual interests. Students’ well-being was measured at the beginning and end of the course. The well-being indicators included positive automatic thoughts, optimism and hope, satisfaction with life, and spirituality. A paired-samples t-test conducted to evaluate the impact of class content and serviceoriented interventions on students’ scores of well-being indicators indicated statistically significant increase from pre-class to post-class scores. There were also significant gender differences in post-course well-being scores, with females having higher levels of well-being than males. A two-way between groups analysis of variance indicated a significant interaction effect of age by gender on the post-course well-being scores, with females in the age group of 56-65 having the highest scores of well-being in comparison to the males in the same age group. Regression analyses indicated that positive automatic thought significantly predicted hope and satisfaction with life in the pre-course analysis. In the post-course regression analysis, spiritual transcendence made a significant contribution to optimism, and positive automatic thought made a significant contribution to both hope and satisfaction with life. Finally, a significant test between precourse and post-course regression coefficients indicated that the regression coefficients at pre-course were significantly different from post-course coefficients, suggesting that the positive psychology course and the interventions were helpful in raising the levels of wellbeing. The overall results suggest a substantial increase in the participants’ well-being scores after engaging in the positive-oriented interventions, implying a need for designing more positive interventions in education to promote well-being. Keywords—Hope, optimism, positive automatic thoughts, satisfaction with life, spirituality, well-being.
