Comparison between multi-constellation ambiguity-fixed PPP and RTK for maritime precise navigation
Authors: Tegedor Javier , Liu Xianglin , Ørpen Ole , Treffers Niels , Goode Matthew , Øvstedal Ola 
Published: June 2015

AbstractIn order to achieve high-accuracy positioning, either Real-Time Kinematic (RTK) or Precise Point Positioning (PPP) techniques can be used. While RTK normally delivers higher accuracy with shorter convergence times, PPP has been an attractive technology for maritime applications, as it delivers uniform positioning performance without the direct need of a nearby reference station. Traditional PPP has been based on ambiguity-­float solutions using GPS and Glonass constellations. However, the addition of new satellite systems, such as Galileo and BeiDou, and the possibility of fixing integer carrier-phase ambiguities (PPP-AR) allow to increase PPP accuracy. In this article, a performance assessment has been done between RTK, PPP and PPP-AR, using GNSS data collected from two antennas installed on a ferry navigating in Oslo (Norway). RTK solutions have been generated using short, medium and long baselines (up to 290 km). For the generation of PPP-AR solutions, Uncalibrated Hardware Delays (UHDs) for GPS, Galileo and BeiDou have been estimated using reference stations in Oslo and Onsala. The performance of RTK and multi-­constellation PPP and PPP-AR are presented.

Abstract
The timely, accurate monitoring of social indicators, such as poverty or inequality, on a finegrained spatial and temporal scale is a crucial tool for understanding social phenomena and policymaking, but poses a great challenge to official statistics. This article argues that an interdisciplinary approach, combining the body of statistical research in small area estimation with the body of research in social data mining based on Big Data, can provide novel means to tackle this problem successfully. Big Data derived from the digital crumbs that humans leave behind in their daily activities are in fact providing ever more accurate proxies of social life. Social data mining from these data, coupled with advanced model-based techniques for fine-grained estimates, have the potential to provide a novel microscope through which to view and understand social complexity. This article suggests three ways to use Big Data together with small area estimation techniques, and shows how Big Data has the potential to mirror aspects of well-being and other socioeconomic phenomena.

Abstract
Data on the food of the Eurasian pygmy owl in Slovakia was collected in 1999−2014 at 12 breeding locations in 7 mountain ranges of the Western Carpathian Mts and 1 range belonging to the Eastern Carpathian Mts. The basis of the evaluation of the food spectrum of prey of G. passerinum was the collection of pellets, osteological remnants and feathers from birds beneath nest cavities and roosting places of females in the months of May to July, that is, in the period of feeding young in the nest. Overall samples of food from 12 nests at elevations of 650−1,260 m a.s.l. were collected; from the largest of the three nests in the upper Nitra Region, from one nest in the Západné Tatry Mts and from three nests in the Volovské vrchy Mts. We compared these data with existing published data from Slovakia. A higher share of birds (65.0%) was found in the obtained material than mammals (34.8%). In the samples from 12 locations 10 species of mammals and 33 species of birds were found among the 377 individual prey samples. Among mammals, forest species of rodents predominated: Clethrionomys glareolus (22.8%) and Apodemus flavicollis (6.6%). The species Microtus arvalis (2.7%) was less abundant than in the stores of food from the Chocské vrchy Mts (35.4%). From the broad spectrum of songbirds, no species exceeded a presence of 7%. Species from the families Sylviidae, Turdidae, Paridae and Fringillidae were more numerous, while the species Phoenicurus phoenicurus, Motacilla alba, Carduelis cannabina, Dendrocopos minor and Passer domesticus were among the more uncommon prey. In total 582 individual prey were determined from the food remnants of G. passerinum in Slovakia (present study and other published studies). The species Clethrionomys glareolus occurred with a higher dominance than average in the pellets of G. passerinum in the mountains which border the region of the upper Nitra. In the Belianské Tatry Mts the most abundant rodent species was Terricola subterraneus, while in the mountains of eastern Slovakia the yellow-necked mouse Apodemus flavicollis was most often hunted, and of the songbirds, the coal tit Periparus ater. Among songbirds hunted near the breeding grounds of G. passerinum in the Považský Inovec Mts the collared flycatcher Ficedula albicollis was the most numerous. Among the most numerous songbirds which are evenly represented in all compared areas were: Regulus sp., Certhia familiaris, Poecile montanus and Cyanistes caeruleus.

AbstractSimilar to neurons in the peripheral nervous system, immature CNS-derived RGCs become dependent on target-derived neurotrophic support as their axons reach termination sites in the brain. To study the factors that influence this developmental transition we took advantage of the fact that rat RGCs are born, and target innervation occurs, over a protracted period of time. Early-born RGCs have axons in the SC by birth (P0), whereas axons from late-born RGCs do not innervate the SC until P4-P5. Birth dating RGCs using EdU allowed us to identify RGCs (1) with axons still growing toward targets, (2) transitioning to target dependence, and (3) entirely dependent on target-derived support. Using laser-capture microdissection we isolated ∼34,000 EdU+RGCs and analyzed transcript expression by custom qPCR array. Statistical analyses revealed a difference in gene expression profiles in actively growing RGCs compared with target-dependent RGCs, as well as in transitional versus target-dependent RGCs. Prior to innervation RGCs expressed high levels of BDNF and CNTFR α but lower levels of neurexin 1 mRNA. Analysis also revealed greater expression of transcripts for signaling molecules such as MAPK, Akt, CREB, and STAT. In a supportingin vitrostudy, purified birth-dated P1 RGCs were cultured for 24-48 h with or without BDNF; lack of BDNF resulted in significant loss of early-born but not late-born RGCs. In summary, we identified several important changes in RGC signaling that may form the basis for the switch from target independence to dependence.

Published: June 2015

Summary
Objectives: Previous research has shown that medication alerting systems face usability issues. There has been no previous attempt to systematically explore the consequences of usability flaws in such systems on users (i.e. usage problems) and work systems (i.e. negative outcomes). This paper aims at exploring and synthesizing the consequences of usability flaws in terms of usage problems and negative outcomes on the work system.
Methods: A secondary analysis of 26 papers included in a prior systematic review of the usability flaws in medication alerting was performed. Usage problems and negative outcomes were extracted and sorted. Links between usability flaws, usage problems, and negative outcomes were also analyzed.
Results: Poor usability generates a large variety of consequences. It impacts the user from a cognitive, behavioral, emotional, and attitudinal perspective. Ultimately, usability flaws have negative consequences on the workflow, the effectiveness of the technology, the medication management process, and, more importantly, patient safety. Only few complete pathways leading from usability flaws to negative outcomes were identified.Conclusion: Usability flaws in medication alerting systems impede users, and ultimately their work system, and negatively impact patient safety. Therefore, the usability dimension may act as a hidden explanatory variable that could explain, at least partly, the (absence of) intended outcomes of new technology.

This Policy Statement was revised. See https://doi.org/10.1542/peds.2021-053129.
The use of telemedicine technologies by primary care pediatricians, pediatric medical subspecialists, and pediatric surgical specialists (henceforth referred to as “pediatric physicians”) has the potential to transform the practice of pediatrics. The purpose of this policy statement is to describe the expected and potential impact that telemedicine will have on pediatric physicians’ efforts to improve access and physician workforce shortages. The policy statement also describes how the American Academy of Pediatrics can advocate for its members and their patients to best use telemedicine technologies to improve access to care, provide more patient- and family-centered care, increase efficiencies in practice, enhance the quality of care, and address projected shortages in the clinical workforce. As the use of telemedicine increases, it is likely to impact health care access, quality, and education and costs of care. Telemedicine technologies, applied to the medical home and its collaborating providers, have the potential to improve current models of care by increasing communication among clinicians, resulting in more efficient, higher quality, and less expensive care. Such a model can serve as a platform for providing more continuous care, linking primary and specialty care to support management of the needs of complex patients. In addition, telemedicine technologies can be used to efficiently provide pediatric physicians working in remote locations with ongoing medical education, increasing their ability to care for more complex patients in their community, reducing the burdens of travel on patients and families, and supporting the medical home. On the other hand, telemedicine technologies used for episodic care by nonmedical home providers have the potential to disrupt continuity of care and to create redundancy and imprudent use of health care resources. Fragmentation should be avoided, and telemedicine, like all primary and specialty services, should be coordinated through the medical home.

Bandolerismo rural en el Bajo Cauca, Magdalena Medio y el Nordeste antioqueño (Colombia), 1953-1958
Authors: Henao Holguín Diana 
Published: June 2015

<p>Este artículo busca contribuir a la discusión sobre el fenómeno del bandolerismo rural desde una perspectiva regional. Explora las zonas del Bajo Cauca, Magdalena Medio y Nordeste antioqueños en Colombia entre 1953 y 1958. En dichos años, el bandolero aparece en el escenario regional tras la descomposición de las guerrillas liberales de la primera fase de La Violencia (1949-1953). Así, adquiere características que difieren del modelo planteado por Eric Hobsbawm, quien propone el concepto <em>bandolerismo social</em> para el análisis de este fenómeno. El artículo evidencia que el análisis contextual permite observar las particularidades del fenómeno y comprender mejor su naturaleza, ya que éstos poseen diversos perfiles que escapan a las explicaciones de tipo general. </p><p> </p>

Objective This study uses the American College of Surgeons Pediatric National Surgical Quality Improvement Program (ACS NSQIP Pediatric), a multicenter database, to identify risk factors for complications after cleft palate repair. Design Patients undergoing Current Procedural Terminology (CPT) codes 42200 and 42205 were extracted from the 2012 ACS NSQIP Pediatric. Patients older than 36 months or those who had undergone an additional surgery that altered the risk were excluded. Outcome variables were combined to create a complication variable. Fisher's exact, Pearson chi-square, and Wilcoxon rank-sum tests were used for analysis. Results Eligibility criteria were met by 751 patients. Of these, 192 (25.6%) had unilateral clefts, 146 (19.4%) bilateral, and 413 (55.0%) were unspecified. The average age at time of surgery for those without and with complications was 421.1 ± 184.8 and 433.6 ± 168.0 days, respectively ( P = .76). Of the 21 (2.8%) patients with complications, respiratory complications were the most common. Risk factors associated with complications included American Society of Anesthesiologists classification of 3 ( P = .003), nutritional support ( P = .013), esophageal/gastric/intestinal disease ( P = .016), oxygen support ( P = .003), structural pulmonary/airway abnormality ( P = .011), and impaired cognitive status ( P = .009). Patients undergoing concurrent laryngoscopy ( P = .048) or other surgeries ( P = .047) were also found to be associated with increased complications. The 30-day fistula rate was 0.5%, and the readmission rate was 1.9%. Conclusion Perioperative complications for primary palatoplasty were 2.8% according to the ACS NSQIP Pediatric. Preoperative patient-related factors as well as concurrent surgeries may affect 30-day complication rates. These results help target those at greater risk for complications and allow for appropriate interventions to mitigate risks.

Abstract
An electrochemically active bacteria Pseudomonas aeruginosa IIT BT SS1 was isolated from a dark fermentative spent media fed anode, and a bioaugmentation technique using the isolated strain was used to improve the start-up time of a microbial fuel cell (MFC). Higher volumetric current density and lower start-up time were observed with the augmented system MFC-PM (13.7 A/m3) when compared with mixed culture MFC-M (8.72 A/m3) during the initial phase. This enhanced performance in MFC-PM was possibly due to the improvement in electron transfer ability by the augmented strain. However, pure culture MFC-P showed maximum volumetric current density (17 A/m3) due to the inherent electrogenic properties of Pseudomonas sp. An electrochemical impedance spectroscopic (EIS) study, along with matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) analysis, supported the influence of isolated species in improving the MFC performance. The present study indicates that the bioaugmentation strategy using the isolated Pseudomonas sp. can be effectively utilized to decrease the start-up time of MFC.
Influence of denitrification reactor retention time distribution (RTD) on dissolved oxygen control and nitrogen removal efficiency
Authors: Raboni Massimo , Gavasci Renato , Viotti Paolo 
Published: June 2015

Abstract
Low concentrations of dissolved oxygen (DO) are usually found in biological anoxic pre-denitrification reactors, causing a reduction in nitrogen removal efficiency. Therefore, the reduction of DO in such reactors is fundamental for achieving good nutrient removal. The article shows the results of an experimental study carried out to evaluate the effect of the anoxic reactor hydrodynamic model on both residual DO concentration and nitrogen removal efficiency. In particular, two hydrodynamic models were considered: the single completely mixed reactor and a series of four reactors that resemble plug-flow behaviour. The latter prove to be more effective in oxygen consumption, allowing a lower residual DO concentration than the former. The series of reactors also achieves better specific denitrification rates and higher denitrification efficiency. Moreover, the denitrification food to microrganism (F:M) ratio (F:MDEN) demonstrates a relevant synergic action in both controlling residual DO and improving the denitrification performance.

Abstract
This study aimed at determining the treatment performances of a full-scale vertical flow constructed wetlands designed to treat wastewater from a food-processing industry (cookie factory), and to study the influence of the organic loading rate. The full-scale treatment plant was designed with a first vertical stage of 630 m², a second vertical stage of 473 m² equipped with a recirculation system and followed by a final horizontal stage of 440 m². The plant was commissioned in 2011, and was operated at different loading rates during 16 months for the purpose of this study. Treatment performances were determined by 24 hour composite samples. The mean concentration of the raw effluent was 8,548 mg.L−1 chemical oxygen demand (COD), 4,334 mg.L−1 biochemical oxygen demand (BOD5), and 2,069 mg.L−1 suspended solids (SS). Despite low nutrients content with a BOD5/N/P ratio of 100/1.8/0.5, lower than optimum for biological degradation (known as 100/5/1), mean removal performances were very high with 98% for COD, 99% for BOD5 and SS for the two vertical stages. The increasing of the organic load from 50 g.m−2.d−1 COD to 237 g.m−2.d−1 COD (on the first stage) did not affect removal performances. The mean quality of effluent reached French standards (COD &lt; 125 mg.L−1, BOD5 &lt; 25 mg.L−1, SS &lt; 35 mg.L−1).
Evaluation of the simultaneous biogas upgrading and treatment of centrates in a high-rate algal pond through C, N and P mass balances

Published: June 2015

Abstract
The simultaneous capture of CO2 from biogas and removal of carbon and nutrients from diluted centrates in a 180 L high-rate algal pond (HRAP) interconnected to a 2.5 L absorption column were evaluated using a C, N and P mass balance approach. The experimental set-up was operated indoors at 75 μE/m2·s for 24 h/d at 20 days of hydraulic retention time for 2 months of steady state, and supported a C-CO2 removal in the absorption column of 55 ± 6%. Carbon fixation into biomass only accounted for 9 ± 2% of the total C input, which explains the low biomass productivity recorded in the HRAP. In this context, the low impinging light intensity along with the high turbulence in the culture broth entailed a C stripping as CO2 of 49 ± 5% of the total carbon input. Nitrification was the main NH4+ removal mechanism and accounted for 47 ± 2% of the inlet N-NH4+, while N removal as biomass represented 14 ± 2% of the total nitrogen input. A luxury P uptake was recorded, which resulted in a P-PO4−3 biomass content over structural requirements (2.5 ± 0.1%). Phosphorus assimilation corresponded to a 77 ± 2% of the inlet dissolved P-PO4−3 removed.
