Novel schemes for local area network emulation in passive optical networks with RF subcarrier multiplexed customer traffic

This paper proposes two novel optical layer schemes for intercommunication between customers in a passive optical network (PON). The proposed schemes use radio frequency (RF) subcarrier multiplexed transmission for intercommunication between customers in conjunction with upstream access to the central office (CO) at baseband. One scheme employs a narrowband fiber Bragg grating (FBG) placed close to the star coupler in the feeder fiber of the PON, while the other uses an additional short-length distribution fiber from the star coupler to each customer unit for the redirection of customer traffic. In both schemes, only one optical transmitter is required at each optical network unit (ONU) for the transmission of customer traffic and upstream access traffic. Moreover, downstream bandwidth is not consumed by customer traffic unlike in previously reported techniques. The authors experimentally verify the feasibility of both schemes with 1.25 Gb/s upstream baseband transmission to the CO and 155 Mb/s customer data transmission on the RF carrier. The experimental results obtained from both schemes are compared, and the power budgets are calculated to analyze the scalability of each scheme. Further, the proposed schemes were discussed in terms of upgradability of the transmission bit rates for the upstream access traffic, bandwidth requirements at the customer premises, dispersion tolerance, and stability issues for the practical implementations of the network.
DATA MINING APPROACH FOR CLASSIFYING TWITTER ’ S USERS

Social networks are the most important communication channels in recent years, which popular among the different social groups. These networks affected the ideas and policies of individuals, groups and communities. Every day, millions of tweets on Twitter are being published. These tweets reflect opinions and beliefs of their publishers and affect others as well. Therefore, it is important to analyze these tweets and identify and classify trends of different users. This research aims to classify social network to anomaly groups such as: Terrorist and dissident; by analyzing tweets data on the Twitter; then identify an anonymous user’s affiliation to these groups. To address this problem, we first extract a set of features to characterize each group using different data mining techniques and store these features in the database. Text mining, sentiment analysis, and opinion mining techniques will be used to accomplish this extraction. The objective of data extraction is to measure the similarity of selected user tweets with respect to extracted features. It will enable to determine high percentage of similarity between the user tweets and group characteristics to expose his/her affiliation to this group.

Public history and popular memory: issues in the commemoration of the British militant suffrage campaign

Abstract Drawing on Raphael Samuel's work on the construction of historical knowledge, this article argues that British militant suffrage feminists had a strong sense of their role in history. Once the vote was won, militants became the first public historians of their own suffrage history by collecting ‘relics’ of the campaign and commemorating suffrage events. The work of curators, especially at the Museum of London and National Library of Australia, Canberra, also enabled wider access to the movement's ephemera. Subsequent generations have ‘remembered’ suffrage in different ways, including depiction in fiction, film, local histories and the physical landscape. An exploration of such depictions might help us start to understand the continuing fascination with this aspect of women's history.
RF HARVESTING USING ANTENNA STRUCTURES ON FOIL

In this paper we present a device for RF harvesting, i.e. harvesting the energy contained in electromagnetic waves. We have designed, modeled and fabricated an RF harvester using optimized antenna structures. Energy densities in e.g. GSM or WiFi frequency bands are very low (< 1 μW/cm), so the harvesting antennas need to have a considerable area. An alternative to ambient RF energy harvesting is to use a dedicated RF source, which enables smaller antenna surfaces.
Once versus twice daily injection of enoxaparin for thromboprophylaxis in bariatric surgery: effects on antifactor Xa activity and procoagulant microparticles. A randomized controlled study.

BACKGROUND
The optimal scheme of thromboprophylaxis in bariatric surgery remains uncertain, because clinical practice is different between countries and randomized trials are lacking.


OBJECTIVES
The primary objective of this randomized multicenter study was to determine the optimal regimen of enoxaparin providing an antifactor Xa peak activity between .3 and .5 IU/mL at equilibrium and to evaluate the course of procoagulant microparticles (MPs).


SETTING
University hospital.


METHODS
A total of 164 patients scheduled for gastric bypass were allocated to 3 groups (A, B, and C) of enoxaparin treatment (4000, 6000, or 2×4000 IU, respectively). Antifactor Xa activity was measured before and 4 hours after each injection from D0 to D2. Doppler screening of the lower limbs was performed at D1, D9, and D30. Bleeding (BE) and thrombotic events (TE) were recorded during the first postoperative month. Total MPs were measured at D0, D9, and D30. MPs of leucocyte, platelet, and granulocyte origin were assessed in one third of the patients from each group. The 3 groups were compared by ANOVA.


RESULTS
A total of 135 patients were analyzed. The equilibrium of antifactor Xa peak levels was obtained 52 hours after the presurgery injection and 12.8%, 56.4%, and 27.3% of the patients reached the target in groups A, B, and C, respectively (P<.001). No TE was detected. BE occurred in 1, 2, and 6 patients in groups A, B, and C, respectively). Total MPs remained unchanged over time. While no significant variation was observed in the other groups, platelet GP1 b(+)-MPs increased (P = .01) at D9 in group C, suggesting an incomplete control of anticoagulation leading to cell activation and procoagulant MP release that was confirmed by the higher MP levels measured at D30 (P = .04). CD66(+)-MPs were also highly elevated at J9 and D30 in group C indicating a granulocyte contribution.


CONCLUSIONS
This study shows that a single dose of enoxaparin 6000 IU/d allowed most of the patients to reach the target range of antifactor Xa activity without increasing the bleeding risk, with the most likely efficient reduction of procoagulant MPs.

Nurses' Perception of Medication Administration Errors

Background: medication administration error (MAE) is one main component for safety healthcare services. The purpose of this study is to investigative factors associated with nurses’ medication administration errors. Design: A descriptive, correlational, cross-sectional design was used. Methods: 309 nurses at two regional hospitals we included and 288 hospital records of medication error analyzed. Medication administration error checklist and hospital records of medication errors were employed to measure the key variables. Results: rate of medication error among nurses was 1.4 times per month (SD = 1.3). The most common factors associated with errors were “Unit staffs do not receive enough in services on new medications” (69.6%, n = 215) and “Poor communication between nurses and physicians” (65.4%, n = 202), while the lowest reported factors was “Physicians change orders frequently” (23.3%, n = 72) and “Physicians' medication orders are not clear” (24.9, n =77). Items analysis also showed that miscommunication with physicians (M=4.51), work overload (staffing) (M= 4.42) had the highest means among all factors. The most reported type of error is the wrong timing of medication administration (30.9%, n = 89). Conclusion: communication, unclear medication orders, workload and medication pancakes were the main factors associate with Medication administration errors.
Named Entity Linking in #Tweets with KEA

This paper presents the KEA system at the #Microposts 2016 NEEL Challenge. Its task is to recognize and type mentions from English microposts and link them to their corresponding entries in DBpedia. For this task, we have adapted our Named Entity Disambiguation tool originally designed for natural language text to the special requirements of noisy, terse, and poorly worded tweets containing special functional terms and language.

Primary care physicians' use of an informed decision-making process for prostate cancer screening.

PURPOSE
Leading professional organizations acknowledge the importance of an informed decision-making process for prostate cancer screening. We describe primary care physicians' reports of their prescreening discussions about the potential harms and benefits of prostate cancer screening.


METHODS
Members of the American Academy of Family Physicians National Research Network responded to a survey that included (1) an indicator of practice styles related to discussing harms and benefits of prostate-specific antigen testing and providing a screening recommendation or letting patients decide, and (2) indicators reflecting physicians' beliefs about prostate cancer screening. The survey was conducted between July 2007 and January 2008.


RESULTS
Of 426 physicians 246 (57.7%) completed the survey questionnaire. Compared with physicians who ordered screening without discussion (24.3%), physicians who discussed harms and benefits with patients and then let them decide (47.7%) were more likely to endorse beliefs that scientific evidence does not support screening, that patients should be told about the lack of evidence, and that patients have a right to know the limitations of screening; they were also less likely to endorse the belief that there was no need to educate patients because they wanted to be screened. Concerns about medicolegal risk associated with not screening were more common among physicians who discussed the harms and benefits and recommended screening than among physicians who discussed screening and let their patients decide.


CONCLUSIONS
Much of the variability in physicians' use of an informed decision-making process can be attributed to beliefs about screening. Concerns about medicolegal risk remain an important barrier for shared decision making.
Quality of life several years after myocardial infarction: comparing the MONICA/KORA registry to the general population.

AIMS
The aim of this study was to assess the impact of myocardial infarction (MI) on health-related quality of life (HRQL) in MI survivors measured by EuroQol (EQ-5D) and to compare it with the general population.


METHODS AND RESULTS
A follow-up study of all MI survivors included in the MONICA/KORA registry was performed. About 2950 (67.1%) patients responded. Moderate or severe problems were most frequent in EQ-5D dimension pain/discomfort (55.0%), anxiety/depression (29.2%), and mobility (27.9%). Mean EQ VAS score was 65.8 (SD 18.5). Main predictors of lower HRQL included older age, diabetes, increasing body mass index, current smoking, and experience of re-infarction. Type of revascularizational treatment showed no impact on HRQL. Compared with the general population, adjusted EQ VAS was 6.2 (95% confidence interval 3.4-8.9) points lower in 45-year-old MI patients converging with growing age up to the age of 80. With regard to HRQL dimensions, MI survivors had a significantly higher risk of incurring problems in the dimension pain/discomfort, usual activities, and especially in anxiety/depression which was more pronounced in younger age. Mobility was the single dimension, in which MI showed an inverse effect.


CONCLUSION
MI is combined with significant reduction in HRQL compared with the general population. The main impairments occur in the dimension pain/discomfort, usual activities, and particularly anxiety/depression. The relative impairment decreases with higher ages.
Late Cenozoic deep weathering patterns on the Fennoscandian shield in northern Finland : A window on ice sheet bed conditions at the onset of Northern Hemisphere glaciation

Abstract The nature of the regolith that existed on the shields of the Northern Hemisphere at the onset of ice sheet glaciation is poorly constrained. In this paper, we provide the first detailed account of an exceptionally preserved, deeply weathered late Neogene landscape in the ice sheet divide zone in northern Finland. We mine data sets of drilling and pitting records gathered by the Geological Survey of Finland to reconstruct regional preglacial deep weathering patterns within a GIS framework. Using a large geochemical data set, we give standardised descriptions of saprolite geochemistry using a variant of the Weathering Index of Parker (WIP) as a proxy to assess the intensity of weathering. We also focus on mineral prospects and mines with dense pit and borehole data coverage in order to identify links between geology, topography, and weathering. Geology is closely linked to topography on the preglacial shield landscape of northern Finland and both factors influence weathering patterns. Upstanding, resistant granulite, granite, gabbro, metabasalt, and quartzite rocks were associated with fresh rock outcrops, including tors, or with thin ( fines values above 3000 and 4000. Beneath valley floors developed along mineralised shear and fracture zones, weathering penetrated locally to depths of > 50 m and included intensely weathered kaolinitic clays with WIP fines values below 1000. Late Neogene weathering profiles were varied in character. Tripartite clay–gruss–saprock profiles occur only in limited areas. Bipartite gruss–saprock profiles were widespread, with saprock thicknesses of > 10 m. Weathering profiles included two discontinuities in texture, materials and resistance to erosion, between saprolite and saprock and between saprock and rock. Limited core recovery when drilling below the soil base in mixed rocks of the Tana Belt indicates that weathering locally penetrated deep below upper fresh rock layers. Such deep-seated weathered bands in rock represent a third set of discontinuities. Incipient weathering and supergene mineralisation also extended to depths of > 100 m in mineralised fracture zones. The thin weathering crusts found extensively beneath till may represent types of early or middle Pleistocene palaeosols. We confirm that glacial erosion has been very limited (
Effects of crystal structure on the uptake of metals by lake trout (Salvelinus namaycush) otoliths

This is the first study to report spectroscopic and elemental analysis of aragonite and vaterite growing simultaneously and separately in both the core and the edges of the same otolith. Our investigations focused on understanding differential trace metal uptake, including the influence of the metal itself (i.e., ionic radii), the crystalline structure, and the development state of the fish. Chemistry and crystal structure of sagittal otoliths from lake trout (Salvelinus namaycush) were studied using laser ablation combined with inductively coupled plasma mass spectrometry (LA-ICPMS) and Raman spectroscopy, respectively. Analyses of the composition of vaterite and aragonite growing in the same growth ring show that smaller cations like Mg (0.86 Å) (1 Å = 0.1 nm) and Mn (0.81 Å) were more abundant in the vaterite hexagonal crystal structure, whereas larger cations such as Sr (1.32 Å) and Ba (1.49 Å) were preferentially incorporated in aragonite (orthorhombic). Similarly, the coprecipitation of aragonite and vaterite in cores and edges allowed us to demonstrate that the uptake rates (as determined by element-specific partition coefficients) for Sr and Ba were greater in aragonite than vaterite, whereas those of Mg and Mn were higher in vaterite than in aragonite. Résumé : C’est la première fois qu’on reporte la cristallisation de l’aragonite et de la vatérite séparément dans le cœur et les anneaux du même otolithe. Nos recherches se concentrent sur la compréhension de l’inclusion des métaux dans l’otolithe. L’incorporation peut varier selon la nature du métal (rayon ionique), la structure cristalline et le stade de développement du poisson. Nous avons étudié la chimie et la composition des cristaux de CaCO3 dans les otolithes sagittales de truites (Salvelinus namaycush) par ablation laser couplée avec un spectromètre de masse atomique à plasma induit (LA-ICP-MS) et par spectroscopie Raman, respectivement. Les analyses sur la composition chimique des deux polymorphes de CaCO3 dans le même anneau d’otolithe, correspondant au même environnement, montrent que les cations de petites tailles tel que Mg (0,86 Å) (1 Å = 0,1 nm) et Mn (0,81 Å) sont plus abondants dans la vatérite, tandis que les cations volumineux comme Sr (1,32 Å) et Ba (1,49 Å) sont préférentiellement incorporés dans l’aragonite. Similairement, la co-précipitation de l’aragonite et de la vatérite dans le cœur et les extrémités de l’otolithe nous a permis de démontrer que les taux d’incorporation (déterminés par les coefficients de partition) de Sr et Ba sont plus élevés dans l’aragonite que dans la vatérite, tandis que ceux de Mg et Mn sont plus élevés dans la vatérite comparativement à l’aragonite.

Risk Factors Associated With Mammalian Target of Rapamycin Inhibitor Withdrawal in Kidney Transplant Recipients.

BACKGROUND
Mammalian target of rapamycin inhibitors (mTORi) play an essential role as novel immunosuppressive agents in kidney transplantation (KT). Treatment cessation usually occurs after adverse effects occur. We investigated the risk factors associated with withdrawal of mTORi in KT recipients and evaluated the outcomes related to the withdrawal.


METHODS
The study enrolled KT recipients being followed up in a medical center in southern Taiwan from January 1999 through December 2014.


RESULTS
Risk factors associated with mTORi withdrawal were initial proteinuria level, higher initial serum creatinine level posttransplantation, and history of glomerulonephritis as the primary etiology of renal failure. mTORi withdrawal was associated with increased risk of graft failure (hazard ratio [HR], 9.97 [95% confidence interval (CI), 1.03-96.8]; P = .047). Higher body mass index (HR, 11.2 [95% CI, 1.63-76.6]; P = .01) and tacrolimus usage (HR, 8.30 [95% CI, 1.14-60.7]; P = .037) were associated with increased risk of new-onset diabetes after transplantation in mTORi withdrawal groups.


CONCLUSIONS
Proteinuria, poor graft function, and primary glomerulonephritis were associated with cessation of mTORi treatment. Earlier identification of these risk factors may prevent further adverse events and optimize transplantation outcomes after mTORi conversion.
basic human values an overview

Introduction to the Values Theory When we think of our values, we think of what is important to us in our lives (e.g., security, independence, wisdom, success, kindness, pleasure). Each of us holds numerous values with varying degrees of importance. A particular value may be very important to one person, but unimportant to another. Consensus regarding the most useful way to conceptualize basic values has emerged gradually since the 1950’s. We can summarize the main features of the conception of basic values implicit in the writings of many theorists and researchers as follows:
GLOBALIZED SECURITIES MARKETS AND ACCOUNTING: HOW MANY STANDARDS? *

SYNOPSIS This paper examines the relationship between globalized securities markets and accounting systems. After describing that globalization, I discuss the reasons for the increase in globalization over the past few decades: changes in government policies and rapid improvements in the technologies-telecommunications and data processing-that underlie finance. I then develop the idea of a financial reporting system as a "network", with the accounting system providing the standards that determine the compatibility between the components of the network. Using this framework, I show the pluses and minuses of a single accounting system versus multiple accounting systems and illustrate the current "systems competition" among national securities markets and their accounting systems. Though a single accounting system decreases comparability costs and thereby encourages globalization, while multiple accounting systems increase comparability costs and thereby impede globalization, those multiple accounting systems also permit national adaptation to national circumstances and permit greater opportunities for experimentation and innovation. On balance, a competitive framework is preferable. The current limited and muted competition between accounting systems could be enhanced by the introduction of the IASB's International Accounting Standards as a second allowable system in the U.S. alongside U.S. GAAP.
