BACKGROUNDRecent studies have failed to show reductions in rates of red blood cell (RBC) transfusion after total joint arthroplasty (TJA) in the United States. This study aims to report the 19‐year trend analysis of blood use in TJA, to determine predictors of RBC transfusion and association between RBC transfusion and in‐hospital mortality after TJA using a nationally representative database.STUDY DESIGN AND METHODSNationwide inpatient sample (NIS) data from 1993 to 2011 were used. ICD‐9‐CM codes were used to identify TJA cases, RBC transfusion, autologous blood transfusion, and/or transfusion from cell salvage. Logistic regression analysis was performed to determine predictors of RBC transfusion and if transfusion increases risk of in‐hospital mortality.RESULTSA total of 2,225,054 TJA cases were identified. Using multivariate analysis, there was an increase in the rate of RBC transfusion over the study period (odds ratio [OR], 1.049; 95% confidence interval [CI], 1.048‐1.050; p < 0.001). One‐stage bilateral TJA (OR, 3.30; 95% CI, 3.24‐3.37; p < 0.001), anemia due to chronic blood loss (OR, 2.69; 95% CI, 2.59‐2.74, p < 0.001), deficiency anemia (OR, 2.59; 95% CI, 2.56‐2.62; p < 0.001), and Charlson comorbidity index (OR, 1.24; 95% CI, 1.23‐1.24; p < 0.001) were independent predictors of allogeneic blood transfusion. Transfusion of autologous blood reduced need for RBC transfusion (OR, 0.84; 95% CI, 0.82‐0.85; p < 0.001). RBC transfusion was an independent predictor of in‐hospital mortality (OR, 1.537; 95% CI, 1.395‐1.694; p < 0.001).CONCLUSIONAn increase in the rate of RBC use after TJA and the association between allogeneic blood transfusion and mortality are worrisome. Implementing more effective blood conservation strategies is recommended.

Published: February 2016

Aim: Reliable liver stiffness measurement (RLSM) using Transient Elastography (TE) with the standard M probe are difficult to obtain in overweight (BMI≥25kg/m2) and obese (BMI>30kg/m2) patients. The aim of our paper was to assess the feasibility of TE in daily practice using both M and XL probes. Material and method: We studied retrospectively 3235 patients with chronic liver disease assessed by TE first by the M probe (standard probe – transducer frequency 3.5 MHz), and if the measurements were unreliable, with the XL probe (transducer frequency 2.5 MHz). Reliable measurements were defined as the median of 10 valid measurements with a success rate ≥ 60% and an interquartile range < 30%. Results of liver elasticity were expressed in kiloPascals (kPa). Results: RLSM by M probe were obtained in 62.2% (2015/3235) patients, and by XL probe in 1011/1220 (80%) of patients with unreliable measurements by M probe; thus we obtained RLSM in 93.5% of 3235 cases.In overweight patients we obtained RLSM in 89.9% (1039/1156) cases: in 63.1% (729) by M probe and in 26.8% (310) by XL probe. In obese patients we obtained RLSM in 83.8% (746/890): in 18.4% (164) by M probe and in 65.4% (582) by XL probe. Thus, by using both probes, RLSM were obtained in 1785 (87.2%) of overweight and obese patients. Conclusion: The feasibility of the M probe was 62.2% in our Department. Reliable measurements using M or XL probe allowed the evaluation of liver stiffness in 93.5% of cases. By using both M and XL probes, reliable LSM by TE can be obtained in the majority of obese and overweight patients (87.2%).
Do Anesthesiologists Know What They Are Doing? Mining a Surgical Time-Series Database to Correlate Expert Assessment with Outcomes

Published: February 2016

Anesthesiologists are taught to carefully manage patient vital signs during surgery. Unfortunately, there is little empirical evidence that vital sign management, as currently practiced, is correlated with patient outcomes. We seek to validate or repudiate current clinical practice and determine whether or not clinician evaluation of surgical vital signs correlate with outcomes. Using a database of over 90,000 cases, we attempt to determine whether those cases that anesthesiologists would subjectively decide are “low quality” are more likely to result in negative outcomes. The problem reduces to one of multi-dimensional time-series classification. Our approach is to have a set of expert anesthesiologists independently label a small number of training cases, from which we build classifiers and label all 90,000 cases. We then use the labeling to search for correlation with outcomes and compare the prevalence of important 30-day outcomes between providers.To mimic the providers’ quality labels, we consider several standard classification methods, such as dynamic time warping in conjunction with a kNN classifier, as well as complexity invariant distance, and a regression based upon the feature extraction methods outlined by Mao et al. 2012 (using features such as time-series mean, standard deviation, skew, etc.). We also propose a new feature selection mechanism that learns a hidden Markov model to segment the time series; the fraction of time that each series spends in each state is used to label the series using a regression-based classifier. In the end, we obtain strong, empirical evidence that current best practice is correlated with reduced negative patient outcomes. We also learn that all of the experts were able to significantly separate cases by outcome, with higher prevalence of negative 30-day outcomes in the cases labeled as “low quality” for almost all of the outcomes investigated.
Parameterized Verification of Asynchronous Shared-Memory Systems

Published: February 2016

We characterize the complexity of the safety verification problem for parameterized systems consisting of a leader process and arbitrarily many anonymous and identical contributors. Processes communicate through a shared, bounded-value register. While each operation on the register is atomic, there is no synchronization primitive to execute a sequence of operations atomically.
We analyze the complexity of the safety verification problem when processes are modeled by finite-state machines, pushdown machines, and Turing machines. The problem is coNP-complete when all processes are finite-state machines, and is PSPACE-complete when they are pushdown machines. The complexity remains coNP-complete when each Turing machine is allowed boundedly many interactions with the register. Our proofs use combinatorial characterizations of computations in the model, and in the case of pushdown systems, some language-theoretic constructions of independent interest. Our results are surprising, because parameterized verification problems on slight variations of our model are known to be undecidable. For example, the problem is undecidable for finite-state machines operating with synchronization primitives, and already for two communicating pushdown machines. Thus, our results show that a robust, decidable class can be obtained under the assumptions of anonymity and asynchrony.
Supporting the Design of Machine Learning Workflows with a Recommendation System

Published: February 2016

Machine learning and data analytics tasks in practice require several consecutive processing steps. RapidMiner is a widely used software tool for the development and execution of such analytics workflows. Unlike many other algorithm toolkits, it comprises a visual editor that allows the user to design processes on a conceptual level. This conceptual and visual approach helps the user to abstract from the technical details during the development phase and to retain a focus on the core modeling task. The large set of preimplemented data analysis and machine learning operations available in the tool, as well as their logical dependencies, can, however, be overwhelming in particular for novice users.
In this work, we present an add-on to the RapidMiner framework that supports the user during the modeling phase by recommending additional operations to insert into the currently developed machine learning workflow. First, we propose different recommendation techniques and evaluate them in an offline setting using a pool of several thousand existing workflows. Second, we present the results of a laboratory study, which show that our tool helps users to significantly increase the efficiency of the modeling process. Finally, we report on analyses using data that were collected during the real-world deployment of the plug-in component and compare the results of the live deployment of the tool with the results obtained through an offline analysis and a replay simulation.
Improving random write performance in homogeneous and heterogeneous erasure-coded drive arrays
Authors: Jeremic Nikolaus , Parzyjegla Helge , Mühl Gero 
Published: February 2016

In data storage systems, drive arrays known as RAIDs are often used in order to avoid data loss and to maintain availability in the event of drive failure(s). RAID schemes define various drive array organizations (denoted as RAID levels) that can be used in arrays of hard disk drives (HDDs) and arrays of NAND flash memory solid-state drives (SSDs). For larger drive arrays, using data striping with erasure coding is appealing due to its notably higher space efficiency compared to data replication. However, the main issue of data striping with erasure coding is the performance of random writes smaller than a stripe. This problem is even aggravated if the random access performance characteristics of the deployed device type (HDD or SSD) and device model are not properly considered when choosing the data striping configuration (in particular the stripe unit size).
In this article, we provide an analytical model allowing to predict the random write throughput of homogeneous drive arrays as well as of a heterogeneous drive array with code blocks stored on the faster drives. Based on our model, we develop a method to improve the random write throughput in homogeneous drive arrays (comprising only one device type, e.g., HDDs or SSDs) by adapting the data striping configuration to the used device type and model in relation to the workload. Then, based on our previous work, we describe an organization for heterogeneous drive arrays, which is especially suitable for arrays combining HDDs with SSDs, and permits to further increase the random write throughput by storing data blocks on slower and code blocks on faster drives. Finally, we experimentally evaluate our analytical claims and show that random write throughput can indeed be notably increased in drive arrays that use data striping with erasure coding.

In the present study, we investigated potential effects of some environmental climatic factors on life-history traits of two Darevskia parvula populations located at different elevation sites and evaluated age, body size, SSD and growth rate results in these lizards. The age at maturity and longevity were found to be similar in both populations. Males of the highland population had significantly larger snout-vent length and older age than those of the lowland population. Although the mean ages of females were not significantly different between the two populations, the highland population had significantly larger snout-vent length than the lowland population. Considering all individuals (both males and females), we found that specimens from the population in the higher-elevation site had significantly larger snout-vent length and older age than those of the lower-elevation site. A low level of male-biased sexual size dimorphism was observed in both populations. The growth coefficient was lower in the high-elevation site than the lower elevation site. Growth rates were not significantly different between the populations. Our preliminary results indicate that although our studied populations were located at different elevation sites and had distinct climate, longevity, age at sexual maturity and growth rate results were similar. This may be a reason of the lower male-biased sexual size dimorphism in both populations.
Molisan cuisine (names of dishes) as an example of multiculturalism and multilingualism

Molisan cuisine (names of dishes) as an example of multiculturalism and multilingualismToday Croats can be found living in many parts of the world. The process of Slavic migrations started in the 7th. Diasporas can be found in Austria, Slovakia, Romania, Czech Republic (Moravia and nowadays Prague), Serbia, Italy, even across the oceans in the USA, South America, RSA and Australia. The Croatian minority in Molise is the smallest Croatian minority in the world. Croatian is spoken there by about 2000 to 2400 people in three isolated mountain communities. They settled in villages, Kruč, Mundimitr and Filić possibly between the 14th and 15th century. Several Turkish invasions took place during this period, so Croats were forced to hide from the Sultan’s armies and they found refuge on the Apennine Peninsula. The country of Croatia, occupied with its battle against the infidels, has forgotten about its fellow countrymen, who had been living in the region of Molis, for a long time. In every day Croatian speech one can hear multiple loan-words. A particular problem can occur when writing some names of dishes which have been passed down but orally only. Molisan-Croatian cuisine and culinary names are part of Croatian cuisine that was created during the time of the Croatian Diaspora. Kuchnia molizańska (nazwy potraw) jako przykład wielokulturowości i wielojęzycznościObecnie Chorwaci żyją na całym świecie. Proces migracji Słowian rozpoczął się już w VII wieku. Ich diaspory możemy odszukać w Austrii, Słowacji, Rumunii, Czechach (na Morawach i w obecnej Pradze) i Serbii, Włoszech, a nawet za oceanem Atlantyckim w USA, południowej Ameryce, RPA i Australii. Najmniejszą chorwacką mniejszością narodową są Molizianie. Językiem chorwackim posługuje się od 2 do 2,4 tysięcy ludzi w trzech odizolowanych społecznościach. Początek osiedlenia się we wsiach: Kruču, Mundimitrze i Filiću określa się na XV–XVI wiek. Okres ten obfituje w najazdy tureckie, kiedy to Chorwaci ukryli się przed armią sułtańską i znaleźli schronienie na Półwyspie Apenińskim. Chorwacja okupowana przez Turków zapomniała o swoich rodakach, którzy żyli w regionie Molise przez dłuższy czas. Język chorwacki pojawia się w mowie potocznej mieszkańców, szczególnie w zapożyczeniach. Szczególnym problemem jest określenie nazw kilku dań, które dotychczas funkcjonowały tylko ustnie. Chorwackomolizańska kuchnia oraz jej nazwy kulinarne są częścią kuchni chorwackiej, która została utworzona w czasach diaspory.

Published: February 2016

AbstractThree infrared (IR) indicators were included in this study: the 10.8-μm brightness temperature (BT10.8), the BT difference between 12.0 and 10.8 μm (BTD12.0–10.8), and the BT difference between 6.7 and 10.8 μm (BTD6.7–10.8). Correlations among these IR indicators were investigated using MTSAT-1R images for summer 2007 over East Asia. Temporal, spatial, and numerical frequency distributions were used to represent the correlations. The results showed that large BTD12.0–10.8 values can be observed in the growth of cumulus congestus and associated with the boundary of different terrain where convection was more likely to generate and develop. The results also showed that numerical correlation between any two IR indicators could be expressed by two-dimensional histograms (HT2D). Because of differences in the tropopause heights and in the temperature and water vapor fields, the shapes of the HT2Ds varied with latitude and the type of underlying surface. After carefully analyzing the correlations among the IR indicators, a conceptual model of the convection life cycle was constructed according to these HT2Ds. A new cloud convection index (CCI) was defined with the combination of BTD12.0–10.8 and BTD6.7–10.8 on the basis of the conceptual model. The preliminary test results demonstrated that CCI could effectively identify convective clouds. CCI value and its time trend could reflect the growth or decline of convective clouds.

Improved methods for detection and arrival picking of microseismic events with low signal-to-noise ratios
Authors: Tan Yuyang , He Chuan 
Published: February 2016

Detection and arrival picking of microseismic events with low signal-to-noise ratios (S/N) are problematic because these events are usually obscured by ambient noise. We have developed an intraevent coherence-based event detection method to address this problem. The innovations of this method include the adaptation of a crosscorrelation, least-squares-based algorithm to achieve better moveout correction for successive record segments and the use of a multichannel semblance coefficient to identify the microseismic events. After finding the events, we adopted a new picker to determine their P- and S-wave arrival times. This picker was developed by combining three aspects of the distinction between seismic signal and ambient noise, namely, the (1) amplitude, (2) polarization, and (3) statistic property differences. We evaluated the performance of the proposed methods using a real data set recorded during an 11-stage hydraulic fracture stimulation. We have determined that, for microseismic event detection, the proposed method has an overall false trigger rate of 12%. As for arrival picking, the average picking error of the new picker is [Formula: see text] and its standard deviation is [Formula: see text]. Comparison of the results of different event detection and arrival picking methods versus the S/N of the data demonstrates that the proposed methods are more applicable for detection and arrival picking of low S/N microseismic events.
Oxygenated Cup-Stacked Carbon Nanofibers/TiO2 Composite Films with Enhanced Photocatalytic Currents

Published: February 2016

Abstract
Oxygenated cup-stacked carbon nanofibers (ox-CSCNFs), the surface of which provides highly ordered graphene edges and oxygen-containing functional groups, were introduced to a nanoporous TiO2 photoelectrode for enhanced photocatalytic currents. The ox-CSCNFs are characterized by good electric conductivity and high dispersibility in solvents. Under UV irradiation, short-circuit photocurrents based on water oxidation at the photoelectrode and oxygen reduction at a counter electrode were enhanced by about 15 times by introduction of the ox-CSCNFs. The oxygen-containing functional groups, which may facilitate good contact between the ox-CSCNFs and TiO2, are essential for the dramatic enhancement in the photocurrent. Recombination efficiency between excited electrons and generated holes may be reduced by facilitated electron transport from excited TiO2 to a substrate electrode via ox-CSCNFs. Photocurrents for photocatalytic oxidation of glucose were also enhanced by about 20-fold. The present composite materials would be applied to photocatalytic and photovoltaic cells with enhanced performances.
Nomenclature of Isotrema, Siphisia, and Endodeca, and their related infrageneric taxa of Aristolochia (Aristolochiaceae)
Authors: Tetsuo Ohi-Toma , Murata Jin 
Published: February 2016

AbstractThe circumscription of Aristolochia L. s.l. (Aristolochiaceae) and its infrageneric taxa has been variable. In some classifications, Aristolochia subg. Siphisia (Raf.) Duch. has often been recognized, but the author citation of the subgenus is incorrect because the generic name Siphisia Raf. is superfluous and illegitimate. In the course of reviewing this author citation, we noticed that the nomenclature for the related genera Isotrema Raf. and Endodeca Raf., and the subtribes Aristolochiinae H.Huber and Isotrematinae H.Huber requires reconsideration. Herein, we review the nomenclatural history of Isotrema, Siphisia, Endodeca, and related genera. We also discuss the related infrageneric taxa of Aristolochia and the subtribes Aristolochiinae and Isotrematinae. Consequently, we confirm that the types of Isotrema and Endodeca and their author citations are I. sipho (L’Hér.) Raf. ex B.D.Jacks. and E. hastata Raf., respectively. In addition, we correct the author citation for Aristolochia subg. Siphisia to (Duch.) O.C.Schmidt. Furthermore, the names Aristolochiinae and Isotrematinae are found to have been invalidly published, since they lacked a Latin description or diagnosis, or reference to earlier validly published names.
