Hollow waveguide-enhanced mid-infrared sensor for fast and sensitive ethylene detection
Authors: Li Jinyi , Du Zhenhui , Zhang Zheyuan , Song Limei , Guo Qinghua 
Published: January 2017

Purpose
This paper aims to provide a sensor for fast, sensitive and selective ethylene (C2H4) concentration measurements.

Design/methodology/approach
The paper developed a sensor platform based on tunable laser absorption spectroscopy with a 3,266-nm interband cascade laser (ICL) as an optical source and a hollow waveguide (HWG) as a gas cell. The ICL wavelength was scanned across a C2H4 strong fundamental absorption band, and an interference-free C2H4 absorption line located at 3,060.76 cm−1 was selected. Wavelength modulation spectroscopy with the second harmonic detection (WMS-2f) technique was used to improve the sensitivity. Furthermore, the HWG gas cell can achieve a long optical path in a very small volume to improve the time response.

Findings
The results show excellent linearity of the measured 2f signal and the C2H4 concentration with a correlation coefficient of 0.9997. Also, the response time is as short as about 10 s. The Allan variance analysis indicates that the detection limit can achieve 53 ppb with an integration time of 24 s.

Practical implications
The ethylene sensor has many meaningful applications in environmental monitoring, industrial production, national security and the biomedicine field.

Originality/value
The paper provides a novel sensor architecture which can be a versatile sensor platform for fast and sensitive trace-gas detection in the mid-infrared region.
Radius based domain clustering for WiFi indoor positioning
Authors: Zhang Wei , Hua Xianghong , Yu Kegen , Qiu Weining , Chang Xin , Wu Bang , Chen Xijiang 
Published: January 2017

Purpose
Nowadays, WiFi indoor positioning based on received signal strength (RSS) becomes a research hotspot due to its low cost and ease of deployment characteristics. To further improve the performance of WiFi indoor positioning based on RSS, this paper aims to propose a novel position estimation strategy which is called radius-based domain clustering (RDC). This domain clustering technology aims to avoid the issue of access point (AP) selection.

Design/methodology/approach
The proposed positioning approach uses each individual AP of all available APs to estimate the position of target point. Then, according to circular error probable, the authors search the decision domain which has the 50 per cent of the intermediate position estimates and minimize the radius of a circle via a RDC algorithm. The final estimate of the position of target point is obtained by averaging intermediate position estimates in the decision domain.

Findings
Experiments are conducted, and comparison between the different position estimation strategies demonstrates that the new method has a better location estimation accuracy and reliability.

Research limitations/implications
Weighted k nearest neighbor approach and Naive Bayes Classifier method are two classic position estimation strategies for location determination using WiFi fingerprinting. Both of the two strategies are affected by AP selection strategies and inappropriate selection of APs may degrade positioning performance considerably.

Practical implications
The RDC positioning approach can improve the performance of WiFi indoor positioning, and the issue of AP selection and related drawbacks is avoided.

Social implications
The RSS-based effective WiFi indoor positioning system can makes up for the indoor positioning weaknesses of global navigation satellite system. Many indoor location-based services can be encouraged with the effective and low-cost positioning technology.

Originality/value
A novel position estimation strategy is introduced to avoid the AP selection problem in RSS-based WiFi indoor positioning technology, and the domain clustering technology is proposed to obtain a better accuracy and reliability.

Authors: Jovic Srdjan , Anicic Obrad , Jovanovic Milivoje 
Published: January 2017

Purpose
Acoustic emission (AE) could be used for prevention and detection of tool errors in Computer Numerical Control (CNC) machining. The purpose of this study is to analyze the AE form of CNC machining operations.

Design/methodology/approach
Experimental measurements were performed with three sensors on the CNC lathe to collect the data of the CNC machining. Adaptive neuro-fuzzy inference system (ANFIS) was applied for the fusion from the sensors’ signals to determine the strength of the signal periodic component among the sensors.

Findings
There were three inputs, namely, spindle speed, feed rate and depth of cut. ANFIS was also used to determine the inputs’ influence on the prediction of strength of the signal periodic component. Variable selection process was used to select the most dominant factors which affect the prediction of strength of the signal periodic component.

Originality/value
Results were shown that the spindle speed has the most dominant effect on the strength of the signal periodic component.

Low migratory connectivity is common in long‐distance migrant birds
Authors: Finch Tom , Butler Simon J. , Franco Aldina M. A. , Cresswell Will 
Published: January 2017

Summary

Estimating how much long‐distance migrant populations spread out and mix during the non‐breeding season (migratory connectivity) is essential for understanding and predicting population dynamics in the face of global change.

We quantify variation in population spread and inter‐population mixing in long‐distance, terrestrial migrant land‐bird populations (712 individuals from 98 populations of 45 species, from tagging studies in the Neotropic and Afro‐Palearctic flyways). We evaluate the Mantel test as a metric of migratory connectivity, and explore the extent to which variance in population spread can be explained simply by geography.

The mean distance between two individuals from the same population during the non‐breeding season was 743 km, covering 10–20% of the maximum width of Africa/South America. Individuals from different breeding populations tended to mix during the non‐breeding season, although spatial segregation was maintained in species with relatively large non‐breeding ranges (and, to a lesser extent, those with low population‐level spread). A substantial amount of between‐population variation in population spread was predicted simply by geography, with populations using non‐breeding zones with limited land availability (e.g. Central America compared to South America) showing lower population spread.

The high levels of population spread suggest that deterministic migration tactics are not generally adaptive; this makes sense in the context of the recent evolution of the systems, and the spatial and temporal unpredictability of non‐breeding habitat.

The conservation implications of generally low connectivity are that the loss (or protection) of any non‐breeding site will have a diffuse but widespread effect on many breeding populations. Although low connectivity should engender population resilience to shifts in habitat (e.g. due to climate change), we suggest it may increase susceptibility to habitat loss. We hypothesize that, because a migrant species cannot adapt to both simultaneously, migrants generally may be more susceptible to population declines in the face of concurrent anthropogenic habitat and climate change.
A lemma science of mind: the potential of the Kegon (Flower Ornament) Sutra
Authors: Nakazawa Shin'ichi 
Published: January 2017

AbstractThe paper argues for a new perspective on the relationship between Buddhism and European psychology, or sciences of the mind, based in the Kegon Sutra, a text that emerged in the early stages of Mahayana Buddhism (3rd ‐ 5th century CE). The basis of European science is logos intellection, formalized by Aristotle as following three laws: the law of identity, the law of contradiction and the law of the excluded middle. Logic in the Buddhist tradition, by contrast, is based in lemma (meaning to understand as a whole not with language, but with intuition). Lemma‐based science born in the Buddhist tradition shows that rational perception is possible even without the three laws of logos. The Kegon Sutra, which explains what Buddha preached only a week after he attained enlightenment, is unified under the logic of lemma and can be seen as an effort to create a ‘lemma science of the mind’. The fundamental teaching of the Kegon Sutra is explored, and its principles are compared with primary process thinking and the unconscious as outlined by Freud and Jung. Jung's research of Eastern texts led him to create a science of the mind that went further than Freud: his concept of synchronicity is given by way of example and can be seen anew within the idea of a lemma‐based science.
Floating worlds and their phantoms in the aftermath of social catastrophes
Authors: Kimbles Samuel 
Published: January 2017

AbstractIn this paper the author describes certain kinds of images (phantoms) that appear in the aftermath of social catastrophes. These phantoms come with an underlying narrative structure, which the author describes as phantom narratives. Phantom narratives show how the unconscious, working at the group and individual levels, provides political and social contexts within which the individual may find a different kind of containment for these catastrophes. In this way their suffering may be potentially processed psychologically and related to symbolically.
The Potential of High‐Dimensional Propensity Scores in Health Services Research: An Exemplary Study on the Quality of Care for Elective Percutaneous Coronary Interventions
Authors: Enders Dirk , Ohlmeier Christoph , Garbe Edeltraut 
Published: January 2017

ObjectiveEvaluating the potential of the high‐dimensional propensity score (HDPS) to control for residual confounding in studies analyzing quality of care based on administrative health insurance data.Data SourceSecondary data from 2004 to 2009 from three German statutory health insurance providers.Study DesignWe conducted a retrospective cohort study in patients with elective percutaneous coronary interventions (PCIs) and compared the mortality risk between the in‐ and outpatient setting using Cox regression. Adjustment for predefined confounders was performed using conventional propensity score (PS) techniques. Further, an HDPS was calculated based on predefined and empirically selected confounders from the database.Principal FindingsConventional PS methods showed a decreased mortality risk for outpatient compared to inpatient PCIs, while trimming of patients with nonoverlap in the HDPS distribution and weighting resulted in a comparable risk. Most comorbidities were less prevalent in the HDPS‐trimmed population compared to the original one.ConclusionThe HDPS methodology may reduce residual confounding by rendering the studied cohort more comparable through restriction. However, results cannot be generalized for the entire study population. To provide unbiased results, full assessment of all unmeasured confounders from proxy information in the database would be necessary.

PURPOSETo critically evaluate 2014 American Academy of Nursing (AAN) call‐to‐action plan for generating interoperable nursing data.DATA SOURCESHealthcare literature.DATA SYNTHESISAAN's plan will not generate the nursing data needed to participate in big data science initiatives in the short term because Logical Observation Identifiers Names and Codes and Systematized Nomenclature of Medicine – Clinical Terms are not yet ripe for generating interoperable data. Well‐tested viable alternatives exist.CONCLUSIONSAuthors present recommendations for revisions to AAN's plan and an evidence‐based alternative to generating interoperable nursing data in the near term. These revisions can ultimately lead to the proposed terminology goals of the AAN's plan in the long term.

SummaryBiodiversity studies are more efficient when large numbers of breeds belonging to several countries are involved, as they allow for an in‐depth analysis of the within‐ and between‐breed components of genetic diversity. A set of 21 microsatellites was used to investigate the genetic composition of 24 Creole goat breeds (910 animals) from 10 countries to estimate levels of genetic variability, infer population structure and understand genetic relationships among populations across the American continent. Three commercial transboundary breeds were included in the analyses to investigate admixture with Creole goats. Overall, the genetic diversity of Creole populations (mean number of alleles = 5.82 ± 1.14, observed heterozygosity = 0.585 ± 0.074) was moderate and slightly lower than what was detected in other studies with breeds from other regions. The Bayesian clustering analysis without prior information on source populations identified 22 breed clusters. Three groups comprised more than one population, namely from Brazil (Azul and Graúna; Moxotó and Repartida) and Argentina (Long and shorthair Chilluda, Pampeana Colorada and Angora‐type goat). Substructure was found in Criolla Paraguaya. When prior information on sample origin was considered, 92% of the individuals were assigned to the source population (threshold q ≥ 0.700). Creole breeds are well‐differentiated entities (mean coefficient of genetic differentiation = 0.111 ± 0.048, with the exception of isolated island populations). Dilution from admixture with commercial transboundary breeds appears to be negligible. Significant levels of inbreeding were detected (inbreeding coefficient > 0 in most Creole goat populations, P < 0.05). Our results provide a broad perspective on the extant genetic diversity of Creole goats, however further studies are needed to understand whether the observed geographical patterns of population structure may reflect the mode of goat colonization in the Americas.

SummaryLocal chicken populations are a major source of food in the rural areas of South America. However, very little is known about their genetic composition and diversity. Here, we analyzed five populations from South America to investigate their maternal genetic origin and diversity, hoping to mitigate the lack of information on local chicken populations from this region. We also included three populations of chicken from the Iberian Peninsula and one from Easter Island, which are potential sources of the first chickens introduced in South America. The obtained sequencing data from South American chickens indicate the presence of four haplogroups (A, B, E and D) that can be further subdivided into nine sub‐haplogroups. Of these, four (B1, D1a, E1a(b), E1b) were absent from local Iberian Peninsula chickens and one (D1a) was present only on Easter Island. The presence of the sub‐haplogroups A1a(b) and E1a(b) in South America, previously only observed in Eastern Asia, and the significant population differentiation between Iberian Peninsula and South American populations, suggest a second maternal source of the extant genetic pool in South American chickens.

Published: January 2017

AbstractFor neuroendocrine tumor G1, local resection is one of the primary treatment options. Endoscopic submucosal dissection has been proven to ensure complete resection with sufficient margins. However, duodenal endoscopic submucosal dissection has a high risk of duodenal perforation because of the thin duodenal wall and poor endoscopic maneuverability. During laparoscopic dissection, suturing can resolve perforation. Therefore, laparoscopic‐endoscopic cooperative surgery (LECS) can ensure complete resection with a minimal margin to prevent stenosis, and suturing can resolve perforation. In short, LECS combines the advantages of both techniques. In the present case, a duodenal neuroendocrine tumor G1 in a 75‐year‐old man was successfully treated using LECS. The patient remained free from recurrence at 21 months postoperatively. LECS is feasible for a neuroendocrine tumor G1 ≤20 mm in size that has not invaded the muscularis propria or the lymphatic and venous vessels.
Adverse reactions to dietary supplements containing red yeast rice: assessment of cases from the Italian surveillance system

Published: January 2017

AimsRed yeast rice (RYR) is contained in dietary supplements for patients with dyslipidemia. RYR supplements contain monacolin K, which is chemically identical to lovastatin, a licensed drug with a well‐known risk profile. We aim to describe the safety profile of RYR by analysing spontaneous reports of suspected adverse reactions (ARs).MethodsWithin the Italian Surveillance System of Natural Health Products, suspected ARs were collected and evaluated by a multidisciplinary group of experts to assess causality using the WHO‐UMC system or the CIOMS/RUCAM score, for hepatic reactions. The public version of the WHO‐Vigibase was also queried.ResultsFrom April 2002 to September 2015, out of 1261 total reports, 52 reports concerning 55 ARs to RYR dietary supplements were collected. ARs consisted in myalgia and/or increase in creatine phosphokinase (19), rhabdomyolysis (1), liver injury (10), gastrointestinal reactions (12), cutaneous reactions (9) and other reactions (4). Women were involved in 70% of cases. In 13 cases, the reaction required hospitalization, and 28 patients were taking other medications. Dechallenge was positive in 40 reactions (73%), rechallenge was positive in 7. Causality resulted as certain (1), probable (31, 56%), possible (18, 34%), unlikely (3) or unassessable (2). Similar distribution emerged from the WHO‐Vigibase.ConclusionsThe potential safety signals of myopathies and liver injury raise the hypothesis that the safety profile of RYR is similar to that of statins. Continuous monitoring of dietary supplements should be promoted to finally characterize their risk profile, thus supporting regulatory bodies for appropriate actions.
Increased regulatory T cell graft content is associated with improved outcome in haematopoietic stem cell transplantation: a systematic review

Published: January 2017

SummaryAllogeneic haematopoietic stem cell transplant (HSCT) recipients are at increased risk of morbidity and mortality, often due to the development of acute or chronic graft‐versus‐host disease (GVHD). Low numbers or proportions of regulatory T cells (Tregs) have been reported in patients who develop GVHD. We undertook a systematic review of studies that reported the Treg composition of HSCT grafts in patients with haematological malignancies. Fourteen eligible studies were identified, eight of which stratified patients by Tregs (absolute dose or ratio to CD3+ or CD4+ cells). Meta‐analyses showed that high levels of Tregs in the grafts were associated with improved overall survival [hazard ratio (HR) 0·42, 95% confidence interval (CI) 0·23–0·74, P = 0·003, 2 studies], with a significant reduction in non‐relapse mortality (HR 0·30, 95% CI 0·14–0·64, P = 0·002, 2 studies) and a reduced risk of acute GVHD (relative risk (RR) 0·59, 95% CI 0·40–0·89, P = 0·01, 6 studies). The consistency of these findings strongly suggests that the Treg composition of HSCT grafts has a powerful effect on the success of allogeneic HSCT. The major challenge is to translate these findings into better selection of allografts and future donors to provide a substantial improvement in allogeneic HSCT outcomes and practice.
