Compact Broadband Dual-Polarized Filtering Dipole Antenna With High Selectivity for Base-Station Applications

This paper presents a broadband dual-polarized filtering dipole antenna for base-station application, which has a compact size of 50 $\text {mm} \times 50\,\,\text {mm} \times 31.8$ mm. The antenna consists of four parts: main radiator, feeding baluns, reflector, and two parasitic loops. Without using complex filtering circuits, the dual-polarized dipole antenna realizes satisfactory filtering performance and enhanced bandwidth by employing only two parasitic loops. Two specific radiation nulls are thus generated and individually controlled by the two parasitic loops. To further improve the upper stopband selectivity and bandwidth, a simple open-ended stub is added to the arms of the dipole. As a result, the bandwidth can be tuned from 7.4% to 47.6%, and the realized gain is decreased dramatically from 8.6 dBi at 2.7 GHz (in-band) to −10 dBi at 2.9 GHz (out-of-band). For demonstration, a broadband dual-polarized dipole antenna is implemented. Measured results show that the proposed antenna has more than 34 dB port isolation over 48.7% (1.66–2.73 GHz) impendence bandwidth (VSWR < 1.5). The measured in-band gain is about 8.15 dBi with stable 3 dB beamwidth 65.4°±2.4° in the horizontal plane, whereas the out-of-band radiation suppression is more than 17 dB.
Oral and Dental Health Does the Autologue Fibrin Glue Enhance the Regeneration of In-trabony Defects in Aggressive Periodontitis ?

Introduction: Aggressive periodontitis is a rapid periodontal destruction that develops in early and affects systemically healthy individuals. As in all periodontal diseases, the main purpose of aggressive periodontitis treatment is to enable the patient to maintain his function and aesthetics with her natural teeth in optimal health conditions. The most appropriate treatment for this purpose is periodontal regeneration methods. In this case report, regenerative treatment of intrabony defects with xenograft and autologue fibrin glue was presented. Methods: A systemically healthy with a history of orthodontic treatment, 23-years-old female patient was referred to our clinic with complaints of infection and mobility in teeth. Localized aggressive periodontitis was diagnosed and intrabony defects were detected as a result of clinical and radiographic examinations. Multiple intrabony defects was detected. Intrabony defects in the mandibula and maxilla were planned to treat with xenograft and barrier membrane after initial periodontal therapy. The usage of xenograft, otogen fibrin glue and barrier membrane were planned to treat the intrabony defect of upper left central incisor tooth. The patient was prescribed antibiotics, anti-inflammatory drug and chlorhexidine gluconate after the operation and sutures were taken at postoperative 10th day. Clinical parameters such as average pocket depth, clinical attachment level, gingival recession and tooth mobility were recorded. Radiographs were taken at baseline, postoperative 3th and 6th month. Results: Postoperative healing of patient was uneventful. Pocket depth was reduced, and satisfactory bone gain was achieved after treatment. Conclusions: As seen in this case, clinically successful results can be achieved by using bone grafts with autologue fibrin glue in the treatment of intrabony defects in aggressive periodontitis.
Job Displacement, Family Dynamics and Spousal Labor Supply

We study the effectiveness of intrahousehold insurance among married couples when the husband loses his job due to a mass layoff or plant closure. Empirical results based on Austrian administrative data show that husbands suffer persistent employment and earnings losses, while wives’ labor supply increases moderately due to extensive margin responses. Wives’ earnings gains recover only a tiny fraction of the household income loss, and in the short-term, public transfers and taxes are a more important form of insurance. We show that the presence of children in the household is a crucial determinant of the wives’ labor supply response. (JEL D13, J12, J16, J22, J31, J63)
Evaluation of Analgesic, Anti-inflammatory and CNS Depressant Potential of Dendrophthoe falcata (Linn.) Leaves Extracts in Experimental Mice Model

Plants are extraordinary reservoir of bioactive natural products, many of which exhibit chemical and structural features on outstanding biological activities in animals. Dendrophthoe falcata (Linn.) is an important parasitic plant extensively used in folk medicine. In this regard, the aim of this study was to investigate the possible analgesic, anti-inflammatory and central nervous system (CNS) depressant activities of ethanol, aqueous, chloroform and petroleum ether extracts of D. falcata (Linn.) leaves (AEDFL, EEDFL, CEDFL and PEDFL) on Swiss albino mice. The analgesic activity was determined by tail immersion and acetic acid induced writhing methods at a dose of 50, 100 and 200 mg/kg, p.o. using morphine sulfate as a standard drug at a dose of 5mg/kg of body weight. Carrageenan-induced paw edema model was applied to find out anti-inflammatory potential at the same doses of analgesic activity. Here ibuprofen was treated as a standard drug at 10mg/kg body weight. The CNS depressant effect of the extracts were evaluated by using open field and hole cross tests. All the extracts exhibited significant (P b < 0.01, P a < 0.001) analgesic, antiinflammatory and CNS depressant effects at dose dependant manner. Petroleum ether extracts (PEDFL) showed maximum analgesic effect (77.45% inhibition of abdominal writhing and 82.12% elongation of tail withdrawal time) at 200mg/kg dose. Moreover, the highest anti-inflammatory potential (90.24% inhibition of paw edema volume) was showed by petroleum ether extract at 200mg/kg dose. On the other hand, ethanol extract (EEDFL) proved to have significant (97.33% and 85.91% inhibition of locomotion in open field and
Exact Equivalence between Quantum Adiabatic Algorithm and Quantum Circuit Algorithm

We present a rigorous proof that quantum circuit algorithm can be transformed into quantum adiabatic algorithm with the exact same time complexity. This means that from a quantum circuit algorithm of L gates we can construct a quantum adiabatic algorithm with time complexity of O(L). Additionally, our construction shows that one may exponentially speed up some quantum adiabatic algorithms by properly choosing an evolution path.
10‐1: Towards Varifocal Augmented Reality Displays using Deformable Beamsplitter Membranes

Growing evidence in recent literature suggests gaze contingent varifocal Near Eye Displays (NEDs) are mitigating visual discomfort caused by the vergence-accommodation conflict (VAC). Such displays promise improved task performance in Virtual Reality (VR) and Augmented Reality (AR) applications and demand less compute and power than light field and holographic display alternatives. In the context of this paper, we further extend the evaluation of our gaze contingent wide field of view varifocal AR NED layout [1] by evaluating optical characteristics of resolution, brightness, and eye-box. Our most recent prototype dramatically reduces form-factor, while improving maximum depth switching time to under 200 ms.
Resisting epistemologies of user-generated content? Cooptation, segregation and the boundaries of journalism

This chapter examines how news organizations are seeking to defend themselves against the incursions of user-generated content through the closely related strategies of cooptation and segregation. In engaging in these strategies, news organizations carry out a form of boundary work to protect the journalistic profession. The chapter takes a closer look at one specific instantiation of cooptation and segregation: The Guardian newspaper’s GuardianWitness, which provides a platform for user-generated content built into the newspaper’s website— just one of many such sites hosted by traditional or “legacy” news media.
Effects of seed size and growth form on seedling establishment of six monocarpic perennial plants

(1) Effects of seed size and seedling morphology on the establishment of six monocarpic perennials were examined in glasshouse experiments. Both withinand between-species comparisons of seed-size effects were made as seed weight varied by more than two orders of magnitude among species and by 3 to 20-fold within a species. Experiments were conducted in four ground-cover types: bare soil, litter cover, vegetated, and vegetated plus litter. (2) In vegetated cover, emergence of the two small-seeded species, Verbascum thapsus and Oenothera biennis, was significantly lower than in litter and bare soil. In contrast, emergence of the medium (Dacus carota and Dipsacus sylvestris) and large-seeded species (Tragopogon dubius and Arctium minus), was not significantly reduced in the presence of vegetation. Although the rate of emergence of all six species was significantly reduced in vegetated cover, there were no between species differences in seedling emergence rates in any cover type. (3) Relative growth rates of all six species were significantly lower in vegetated cover compared with litter and bare soil and the effect was greatest on the small-seeded species. At the end of the experiment, seedling weight in vegetated cover was positively correlated with seed weight. In non-competitive cover types (litter and bare soil), seedling weight was independent of initial seed weight. (4) Relative growth rates of seedlings in non-competitive cover types were inversely related to seed size. In bare soil and litter, the small-seeded species had relative growth rates twice those of the large-seeded species. In vegetated cover this pattern was reversed; the species with large seeds had the highest relative growth rates. (5) The growth form of a seedling did not have any effect on its probability of establishment in any cover type. Species with different growth forms and similar seed sizes had equal emergence, survival, and relative growth rates in all four cover types. (6) Within species differences in seed size had a significant effect on seedling growth in non-competitive cover, but had no effect on seedling growth in competitive cover. Thus, both withinand between-species differences in seed size had similar effects on seedling establishment success in different types of ground cover.
Wind Erosion and Visibility Problems

IND erosion frequently suspends enough particuw lates to create visibility hazards near highways and airports. How much visibility is reduced depends on both the concentration and size distribution of the particulates. For typical conditions, 100 to 400 mg/m3 are needed to reduce daytime visibility to 200 m. If the background is non-sky, visibility is reduced an additional 50 to 75 percent compared with a sky background and, if one is facing the sun, visibility is reduced even further. Particulate concentrations can be reduced by reducing the source emission rate or by diffusing and trapping the particulates. A combination of these methods may be needed where wind erosion is severe.
Excess Capacity and Heterogeneity in the Fiscal Multiplier : Evidence from the Obama Stimulus Package ⇤

We estimate local multipliers from the ARRA (Obama stimulus) bill using cross-county variation in expenditure. We use within-state variation, and include other demographic controls as well as a predicted employment control using an industry shift-share measure. We estimate a peak annualized employment multiplier of 1 job-year per $100K spent per county resident and a 2 year average multiplier of 0.75. We do not find nonlinearity in the marginal treatment e↵ect of a dollar in stimulus spending, but do find strong evidence of heterogeneous treatment e↵ects: the employment response is much greater in counties with greater excess capacity. In above median excess capacity counties, the 2 year multiplier is 1.38. The level of spatial aggregation of the estimation has a large impact on estimation. Spatially aggregated multipliers rise to as high as 3.28 jobs per $100K spent per resident. Our smaller county-level estimates imply that ARRA created 1.97 million jobs. A spatially optimal stimulus, targeted to high excess capacity counties, would have created 83% more (3.60 million) jobs. Our cross-sectional results are consistent with macro-economic models with state-dependent fiscal multipliers. In addition, they also suggest that the state dependency arises from the presence of excess capacity in the economy during deep recessions, and not solely due to the zero lower bound on nominal interest rate. Our evidence is also inconsistent with equilibrium models where a positive multiplier arises from a drop in wealth resulting in an increase in the labor
Comparison of a Time Efficient to Standard Stretching Protocol for Short-Term Flexibility Improvements

Marucci R, Heck A, Ferraro E, Kudrna R. Comparison of a Time Efficient to Standard Stretching Protocol for Short-Term Flexibility Improvements. JEPonline 2016;19(5):49-58. The purpose of this study was to compare the effectiveness of a short-term flexibility protocol to a standard stretching protocol. Twenty-three healthy college-aged volunteers (18 to 22 yrs of age) were randomly divided into three groups: Experimental (EXP), Standard (STD), and Control (CON). The 5-min EXP protocol involved three stretches targeting chronic adaptive shortening while the 10-min STD protocol consisted of six conventional stretches. Hip flexion measurements with a goniometer, functional double reach test, straddle groin flexibility test, and modified sit-and-reach were used to assess flexibility before and after completed 8 sessions over 2 wks. A Kruskal-Wallis analysis identified a significant difference between groups for overall ranked flexibility improvements (H(2)=7.159, P=0.028). The post hoc Mann-Whitney U Test identified significant flexibility improvements in the EXP and STD groups compared to the CON group, but no significant difference in flexibility between the EXP and STD groups. The EXP stretching protocol improved overall flexibility as much as the STD protocol in half the time. Future studies will need to examine if the time effective protocol yields greater adherence among clients.
Onto what planes should Coulomb stress perturbations be resolved

[1] Coulomb stress maps are produced by computing the tensorial stress perturbation due to an earthquake rupture and resolving this tensor onto planes of a particular orientation. It is often assumed that aftershock fault planes are “optimally oriented”; in other words, the regional stress and coseismic stress change are used to compute the orientation of planes most likely to fail and the coseismic stress is resolved onto these orientations. This practice assumes that faults capable of sustaining aftershocks exist at all orientations, an assumption contradicted by the observation that aftershock focal mechanisms have strong preferred orientations consistent with mapped structural trends. Here we systematically investigate the best planes onto which stress should be resolved for the Landers, Hector Mine, Loma Prieta, and Northridge earthquakes by quantitatively comparing observed aftershock distributions with stress maps based on optimally oriented planes (two- and three-dimensional), main shock orientation, and regional structural trend. We find that the best model differs between different tectonic regions but that in all cases, models that incorporate the regional stress field tend to produce stress maps that best fit the observed aftershock distributions, although not all such models do so equally well. Our results suggest that when the regional stress field is poorly defined, or in structurally complex areas, the best model may be to fix the strike of the planes upon which the stress is to be resolved to that of the main shock but allow the dip and rake to vary.
Improving moving jam detection performance with V 2 I communication

Dynamax is a road side based system using the SPECIALIST control algorithm and inductive loops. Dynamax field tests showed that moving jams can be effectively resolved by dynamic speed measures [1,5]. This paper focuses on Dynamax In Car, which extends the road side infrastructure with a V2I cooperative approach. V2I cooperation is used to detect an emerging jam earlier and more accurately, so that a smaller speed measure can be set to resolve it and larger moving jams can be resolved within the available road length. The detection performance is analyzed through simulation and found to improve already with a very low penetration rate. An additional road side detection system is also analyzed that is independent of the penetration rate and provides the best detection performance.
The Effects of Epidural Anesthesia and General Anesthesia on Newborns at Cesarean Section

We compared Apgar scores and umblical arterial and venous blood gas samples of infants following the application of general anesthesia or lumbar epidural anesthesia during cesarean section. Sixty-two pregnant women whose babies were to be delivered at term by cesarean section were recruited for this study and randomized to receive either general anesthesia (GA) (n = 31), or lumbar epidural anesthesia (EA) (n = 31). Following delivery, a segment of the umbilical cord was doubly clamped, and arterial and venous blood gas samples were taken. In both groups, Apgar scores were recorded at 1 and 5 min. There were no significant differences between the 2 groups for 1 min Apgar scores (P > 0.05). In the GA group, 5 min Apgar scores were significantly lower than those of the EA group (P < 0.05). However, no treatment was required. In addition, when comparing the groups, no significant difference in umbilical cord arterial and venous blood gas analyses was noted (P < 0.05).
Unbiased Prediction Model for Frequency Non-Selective Fading Channels

The prediction of the frequency non-selective fading channel behaviors is investigated. An adaptive method is implemented based on an autoregressive model of the past fading measurements in the sense of LMSE and the future fading multiplicative gain is predicted. To mitigate the influence of the noise interference and the disturbance of the non-stationary environment factors, the combination of a pre-filter and a γ-LMS prediction error filter is used. Lastly we give the performance evaluation for the prediction algorithm based on simulations. It shows that the proposed prediction scheme has improved capability in combating against the noise interference.
Understanding irony: an ERP analysis on the elaboration of acoustic ironic statement

Irony is part of our daily experience, that is probably the reason why a lot of studies have been trying to define its nature and the way we are able to understand the pragmatic intentions lying behind ironic communication. This study addresses the issue of pragmatic comprehension of language by analysing the differences or similarities in processing ironical and non-ironical language. The aim of the study is specifically to explore neuropsychological correlates (ERPs) of irony decoding. 10 subjects listened to 240 sentences presenting a counterfactual vs. non-counterfactual content (counterfactual modality) and spoken with ironical vs. neutral prosody (prosody modality). ERPs analysis showed a negative deflection peaking at about 460ms post stimulus onset (N400) for all the conditions. Statistical analyses (repeated measures ANOVA) applied to peak amplitudes showed no statistically significant differences between the conditions as a functions of the type of sentence (ironical vs. non ironical) and the content of ironical sentences (counterfactual vs. non counterfactual). An increase of N400 related to ironical sentences was observed although no statistical significant differences between ironical and non ironical sentences were found. The absence of an N400 effect may indicate that irony is not treated as a semantic anomaly, thus rejecting the standard pragmatic hypothesis. The observed differences in amplitude could be probably attributed to a higher requirement for the cognitive resources in order to integrate contrasting and complex lexical, prosodic and contextual cues.
Effect of short term infection of Paradactylogyrus catlaius on selected haematological and non-specific immune parameters in Catla catla (Hamilton, 1822)

A short term (20 days) cohabitation infection study of the gill fluke Paradactylogyrus catlaius infecting Catla catla was conducted to investigate on the mode, intensity and effect of infection on selected haematological, immunological and serum biochemical parameters in the infected fish. The results revealed that the increase in the number of parasites is rampant and increased to 161±23 parasites per gill lamella in just 20 days post-challenge. Further, significant decrease (p≤0.05) in haemoglobin (Hb), total erythrocyte count (TEC), lysozyme activity, bactericidal activity, total protein and albumin content was noticed whereas a significant increase in total leucocyte count (TLC) was recorded. Globulin content and superoxide anion production increased significantly initially and then decreased (p≤0.05). From this study, it was found that P. catlaius infection causes no mortality in catla till the 20th day of challenge but the infection can spread to the whole population of catla in short time. Further, it was also observed that the infection can adversely affect the physiological and immunological status of the infected fish. Therefore, appropriate management and control strategies need to be formulated to prevent its spread and to avoid production los
Analyzing and Modeling a City’s Spatiotemporal Taxi Supply and Demand: A Case Study for Munich

This paper presents a method for studying supply and demand in a taxi network in time and space by using the example of Munich. First, we introduce the necessary data collection that is linked to a fleet management system (FMS) operated by a local taxi agency and create a statistically sound database, which represents the mobility behavior on a trip level. Second, we derive key figures describing the city’s taxi characteristics. Here both the temporal taxi supply and demand of 420 taxis over a period of 19 weeks is considered. As the taxi demand differs according to the city district, the investigated area has to be divided into various zones. We analyze their specific characteristics and describe key factors influencing taxi requests, such as weekdays, public holidays and number of point of interests within an area. Next, a model to predict a time-variant demand for individual districts is introduced. We classify the problem and choose an appropriate algorithm to forecast spatiotemporal taxi requests. As booking actions differ over time, a nonhomogeneous Poisson distribution is suitable for counting those events. In a final step, we validate the proposed model on a local and global scale. Our model helps to provide a better understanding of taxi fleet operations on a city scale. We use the suggested demand prediction as one input parameter for an agent-based fleet simulation that represents individual taxi movements. 
