Suspected anaphylaxis after intravenous injection of rocuronium in a dog
Authors: Küls Nina , Rocchi Attilio , Larenza Paula Maria 
Published: September 2016

A nine‐year‐old female Yorkshire Terrier weighing 5.8 kg required anaesthesia for a bilateral phacoemulsification to treat diabetic cataracts. Perioperatively, rocuronium bromide was administered intravenously to achieve centralisation of the eye. Immediately after injection of the rocuronium, the dog developed tachycardia, hypertension and bronchospasm. At this time, no association between the rocuronium and the adverse reaction was made due to the lack of reports of such an event in dogs. A second dose was therefore administered once the animal's spontaneous efforts to breathe indicated partial loss of neuromuscular blockade, this time without adverse effects. However, a third dose of rocuronium resulted in similar signs as the first injection, suggesting an association between the rocuronium and the observed reaction. The signs resolved spontaneously and the dog recovered uneventfully in the intensive care unit from where it was discharged 48 hours after the surgery.

Published: September 2016

The effect of pressure on the structural, elastic and electronic properties of the intermetallic compound MgCu with a CsCl-type structure have been investigated using ab initio technique. The optical properties have been studied under normal pressure. We have carried out the plane-wave pseudopotential approach within the framework of the first-principles density functional theory (DFT) implemented within the CASTEP code. The calculated structural parameters show a good agreement with the experimental and other theoretical results. The most important elastic properties including the bulk modulus [Formula: see text], shear modulus [Formula: see text], Young’s modulus [Formula: see text] and Poisson’s ratio [Formula: see text] of the cubic-type structure MgCu are determined under pressure by using the Voigt–Reuss–Hill (VRH) averaging scheme. The results show that the MgCu intermetallic becomes unstable under pressure more than 15 GPa. The study of Cauchy pressure and Pugh’s ratio exhibit brittle nature of MgCu at ambient condition and the compound is transformed into ductile nature with the increase of pressure. For the first time we have investigated the electronic and optical properties of MgCu. The electronic band structure reveals metallic conductivity and the major contribution comes from Cu-[Formula: see text] states. Reflectivity spectrum shows that the reflectivity is high in the ultraviolet region up to 72 eV.

Published: September 2016

The paper deals with the optimal sizing of the contact center. The most important part of the contact centers are their agents, therefore the modeling of their working time is also important. In the case of parameter which describes the number of handled calls during the peak hour also the other factors should be taken into account, such as time for hygienic break and time for other activities after serving of the customer. Such modified parameter can be used in Erlang C equation for calculation of optimal number of the contact center agents.

Published: September 2016

Background and Purpose—
Clinical identification of stroke in the pediatric emergency department is critical for improving access to hyperacute therapies. We identified key clinical features associated with childhood stroke or transient ischemic attack compared with mimics.

Methods—
Two hundred and eighty consecutive children presenting to the emergency department with mimics, prospectively recruited over 18 months from 2009 to 2010, were compared with 102 children with stroke or transient ischemic attack, prospectively/retrospectively recruited from 2003 to 2010.

Results—
Cerebrovascular diagnoses included arterial ischemic stroke (55), hemorrhagic stroke (37), and transient ischemic attack (10). Mimic diagnoses included migraine (84), seizures (46), Bell’s palsy (29), and conversion disorders (18). Being well in the week before presentation (odds ratio [OR] 5.76, 95% confidence interval [CI] 2.25–14.79), face weakness (OR 2.94, 95% CI 1.19–7.28), arm weakness (OR 8.66, 95% CI, 2.50–30.02), and inability to walk (OR 3.38, 95% CI 1.54–7.42) were independently associated with increased odds of stroke diagnosis. Other symptoms were independently associated with decreased odds of stroke diagnosis (OR 0.28, 95% CI 0.10–0.77). Associations were not observed between seizures or loss of consciousness. Factors associated with stroke differed by arterial and hemorrhagic subtypes.

Conclusions—
Being well in the week before presentation, inability to walk, face and arm weakness are associated with increased odds of stroke. The lack of positive or negative association between stroke and seizures or loss of consciousness is an important difference to adults. Pediatric stroke pathways and bedside tools need to factor in differences between children and adults and between stroke subtypes.
Population Aging and Potential Growth in Asia
Authors: Otsu Keisuke , Shibayama Katsuyuki 
Published: September 2016

We study the effects of projected population aging on potential growth in Asian economies over the period 2015–2050. We find that an increase in the share of the population over 64 years of age will significantly lower output growth through decreased labor participation. Population aging can also reduce economic growth through increased labor income taxes and dampened productivity growth.
Arendt and Benjamin: Tradition, Progress and Break with the Past
Authors: Demiryol Gaye İlhan 
Published: September 2016

Abstract
This essay explores the influence of Benjamin’s fragmentary historiography on Arendt’s understanding of narrative. I argue that Arendt and Benjamin shared a common understanding of the problems of modernity. For both thinkers contemporary conditions of existence were defined on the one hand, by a similar conception of history, and on the other hand, a break with the tradition of philosophy. I demonstrate that Benjamin’s fragmented history, adopted by Arendt in response to this contemporary politico-philosophical crisis, allowed her to redeem the past as a basis of a future-oriented philosophy by creating a space for arresting the continuum of history and asserting the importance of human agency.
Was Emily Brown American Empress in Korea?
Authors: Yoon Jong-pil 
Published: September 2016

Abstract
This paper investigates the limits and meaning of historical inquiry in light of inferential contextualism that holds as its central tenet that the epistemic status of a proposition depends on the context of the subject. Historical inquiry, the discussion will show, is an epistemic practice that operates under the reliabilist presupposition that beliefs formed through the processes, whose pragmatic utility has been already proven in problem solving situations, may be taken to be rationally justified.
As for the limits of historical inquiry, it will be pointed out that the practice is unable to achieve independent criteria for determining if the belief it produces correctly reflects the thing in reality it purports to be about and thus correspondence between the former and the latter cannot be established. Furthermore, beliefs formed by historical inquiry cannot be rendered verifiable even through a future-oriented pragmatic theory of truth because it inquires into what happened in the past, not what is to happen in the future.
Despite the fact that we cannot tell the truth about the past in any certain and direct way, it is, the paper will conclude, still epistemically meaningful to distinguish justified from unjustified beliefs in history because historical inquiry is so closely connected with everyday epistemic practice through sharing pragmatically sustained processes that the former cannot be discarded without giving up the principles of the latter. There lies the meaning of historical inquiry.
Taxonomic changes in Cleveaceae (Marchantiidae, Marchantiophyta)—a correction
Authors: LONG DAVID G. , CRANDALL-STOTLER BARBARA J. 
Published: September 2016

The recently published combination Clevea nana (Lindenb.) Crand.-Stotl. & D.G.Long, which was intended to replace the name Clevea hyalina (Sommerf.) Lindb. on the basis of nomenclatural priority, is a later homonym of Clevea nana (Shimizu & S.Hatt.) Borovichev & Bakalin published in 2013 for a different taxon. Consequently, the name Clevea hyalina is the correct name for the widespread dioicous member of the genus. The heterotypic name Clevea nana (Shimizu & S.Hatt.) Borovichev & Bakalin refers to a different monoicous species of the genus that had previously been placed in synonymy of Clevea pusilla (Steph.) Rubasinghe & D.G.Long.
Statistical Weather-Impact Models: An Application of Neural Networks and Mixed Effects for Corn Production over the United States
Authors: Mathieu Jordane A. , Aires Filipe 
Published: September 2016

AbstractStatistical meteorological impact models are intended to represent the impact of weather on socioeconomic activities, using a statistical approach. The calibration of such models is difficult because relationships are complex and historical records are limited. Often, such models succeed in reproducing past data but perform poorly on unseen new data (a problem known as overfitting). This difficulty emphasizes the need for regularization techniques and reliable assessment of the model quality. This study illustrates, in a general way, how to extract pertinent information from weather data and exploit it in impact models that are designed to help decision-making. For a given socioeconomic activity, this type of impact model can be used to 1) study its sensitivity to weather anomalies (e.g., corn sensitivity to water stress), 2) perform seasonal forecasting (yield forecasting) for it, and 3) quantify the longer-term (several decades) impact of weather on it. The size of the training database can be increased by pooling data from various locations, but this requires statistical models that are able to use the localization information—for example, mixed-effect (ME) models. Linear, neural-network, and ME models are compared, using a real-world application: corn-yield forecasting over the United States. Many challenges faced in this paper may be encountered in many weather-impact analyses: these results show that much care is required when using space–time data because they are often highly spatially correlated. In addition, the forecast quality is strongly influenced by the training spatial scale. For the application that is described herein, learning at the state scale is a good trade-off: it is specific to local conditions while keeping enough data for the calibration.
Future Changes in Mean and Extreme Monsoon Precipitation in the Middle and Lower Yangtze River Basin, China, in the CMIP5 Models

Abstract
In this study, the potential future changes of mean and extreme precipitation in the middle and lower Yangtze River basin (MLYRB), eastern China, are assessed using the models of phase 5 of the Coupled Model Intercomparison Project (CMIP5). Historical model simulations are first compared with observations in order to evaluate model performance. In general, the models simulate the precipitation mean and frequency better than the precipitation intensity and extremes, but still have difficulty capturing precipitation patterns over complex terrains. They tend to overestimate precipitation mean, frequency, and intensity while underestimating the extremes. After correcting for model biases, the spatial variation of mean precipitation projected by the multimodel ensemble mean (MME) is improved, so the MME after the bias correction is used to project changes for the years 2021–50 and 2071–2100 relative to 1971–2000 under two emission scenarios: RCP4.5 and RCP8.5. Results show that with global warming, precipitation will become less frequent but more intense over the MLYRB. Relative changes in extremes generally exceed those in mean precipitation. Moreover, increased precipitation extremes are also expected even in places where mean precipitation is projected to decrease in 2021–50. The overall increase in extreme precipitation could potentially lead to more frequent floods in this already flood-prone region.
Impact of a Localized Source of Subglacial Discharge on the Heat Flux and Submarine Melting of a Tidewater Glacier: A Laboratory Study
Authors: Cenedese Claudia , Gatto V. Marco 
Published: September 2016

AbstractIdealized laboratory experiments have been conducted in a two-layer stratified fluid to investigate the leading-order dynamics that control submarine melting and meltwater export near a vertical ice–ocean interface as a function of subglacial discharge. In summer, the discharge of surface runoff at the base of a glacier (subglacial discharge) generates strong buoyant plumes that rise along the glacier front entraining ambient water along the way. The entrainment enhances the heat transport toward the glacier front and hence the submarine melt rate increases with the subglacial discharge rate. In the laboratory, the effect of subglacial discharge is simulated by introducing freshwater at freezing temperature from a point source at the base of an ice block representing the glacier. The circulation pattern observed both with and without subglacial discharge resembles those observed in previous observational and numerical studies. Buoyant plumes rise vertically until they find either their neutrally buoyant level or the free surface. Hence, the meltwater can deposit within the interior of the water column and not entirely at the free surface, as confirmed by field observations. The heat budget in the tank, calculated following a new framework, gives estimates of submarine melt rate that increase with the subglacial discharge and are in agreement with the directly measured submarine melting. This laboratory study provides the first direct measurements of submarine melt rates for different subglacial discharges, and the results are consistent with the predictions of previous theoretical and numerical studies.
Multisensor Characterization of Mammatus

Published: September 2016

Abstract
Multisensor observations of anvil mammatus are analyzed in order to gain a more detailed understanding of their spatiotemporal structure and microphysical characterization. Remarkable polarimetric radar signatures are detected for the Pentecost 2014 supercell in Northrhine Westfalia, Germany, and severe storms in Oklahoma along their mammatus-bearing anvil bases. Radar reflectivity at horizontal polarization ZH and cross-correlation coefficient ρHV decrease downward toward the bottom of the anvil while differential reflectivity ZDR rapidly increases, consistent with the signature of crystal depositional growth. The differential reflectivity ZDR within mammatus exceeds 2 dB in the Pentecost storm and in several Oklahoma severe convective storms examined for this paper. Observations from a zenith-pointing Ka-band cloud radar and a Doppler wind lidar during the Pentecost storm indicate the presence of a supercooled liquid layer of at least 200–300-m depth near the anvil base at temperatures between −15° and −30°C. These liquid drops, which are presumably generated in localized areas of vertical velocities of up to 1.5 m s−1, coexist with ice particles identified by cloud radar. The authors hypothesize that pristine crystals grow rapidly within these layers of supercooled water, and that oriented planar ice crystals falling from the liquid layers lead to high ZDR at precipitation radar frequencies. A mammatus detection strategy using precipitation radar observations is presented, based on a methodology so far mainly used for the detection of updrafts in convective storms. Owing to the presence of a supercooled liquid layer detected above the mammatus lobes, the new detection strategy might also be relevant for aviation safety.

Published: September 2016

Objective: Progressive multifocal leukoencephalopathy (PML) is an emerging complication of immunosuppressive therapies, especially natalizumab in multiple sclerosis (MS). Factors associated with functional outcome of natalizumab-associated PML (natalizumab-PML) have not been sufficiently described. Methods: We retrospectively analyzed medical records of all patients with natalizumab-PML ( n = 32) treated in our hospital since 2009. Disability measured by Expanded Disability Status Scale (EDSS) at two different time points (highest available EDSS during PML and last available EDSS after PML diagnosis) served as functional outcome parameters. Clinical, laboratory, and imaging data were analyzed for association with functional outcome by applying Spearman’s rho and multivariate regression analysis. Results: In all, 31/32 patients survived PML. A poor functional outcome was associated with higher age, higher initial John Cunningham virus (JCV) copy number in cerebrospinal fluid (CSF), and more extensive PML lesions on initial magnetic resonance imaging (MRI). No association between functional outcome and the duration of natalizumab therapy or a delayed PML diagnosis was observed. Conclusion: This study will be useful for neurological practice to estimate functional outcome or disease severity of natalizumab-PML in primary care settings.

Published: September 2016

The Quick disabilities of the arm, shoulder and hand (QuickDASH) patient-reported outcome measure is frequently used to assess disabilities and symptoms of the upper extremity. This study compares real preoperative QuickDASH scores and remembered preoperative QuickDASH scores. Remembered preoperative QuickDASH scores were obtained 45 months (39–67) after surgery. Patient material consisted of 160 patients operated for Dupuytren’s contracture, carpal tunnel syndrome, thumb basal joint arthrosis, and shoulder pain. All patients had completed QuickDASH questionnaires before surgery. Paired T-tests, linear mixed models, and limits of agreement were used for analyses. There was a significant difference between remembered and real preoperative scores (mean 7.6, SD 15.6; SEM 1.2). Neither diagnosis, age, gender, nor time between surgery and review influenced the difference significantly. A linear mixed model was constructed to investigate the ability to retrospectively predict preoperative QuickDASH scores. Remembered preoperative QuickDASH cannot be used in individual patients because of the high inaccuracy. Level of evidence: III

Published: September 2016

Background The Skull Base Inventory (SBI) was developed to assess the quality of life of patients undergoing endoscopic or open approaches for anterior and central skull base pathologies. In this study, we sought to establish the discriminative and evaluative properties for this instrument. Methods The SBI was administered in a cross-sectional fashion to patients who previously had skull base surgery after treatment and then again 2 weeks after completing the instrument. Internal consistency, test-retest reliability, and construct validity were determined. Four constructs were evaluated with the following a priori hypotheses: lower scores will be seen in patients with 1.malignant versus benign histology, 2.a history of radiation versus none, and those with 3.recurrences versus no recurrence, and 4.items deemed relevant versus irrelevant by respondents. Results Fifty-two patients completed the questionnaire; 32 had endoscopic and 20 open surgeries. Internal consistency was good (>0.7 and <0.95) for all domains except one. Test-retest reliability was good (>0.70) for 38 of 41 items. Four constructs were evaluated and three were consistent with a priori hypotheses ( p < 0.05). The instrument failed to confirm the hypothesis that malignant tumours are associated with poorer scores than benign. Conclusions The SBI demonstrated preliminary reliability and validity for discriminative use.

Published: September 2016

AbstractEnterococcus faecium, traditionally considered a harmless gut commensal, is emerging as an important nosocomial pathogen showing increasing rates of multidrug resistance. We report the draft genome sequence of E. faecium strain LMG 8148, isolated in 1968 from a human in Gothenburg, Sweden. The draft genome has a total length of 2,697,490 bp, a GC-content of 38.3 %, and 2,402 predicted protein-coding sequences. The isolation of this strain predates the emergence of E. faecium as a nosocomial pathogen. Consequently, its genome can be useful in comparative genomic studies investigating the evolution of E. faecium as a pathogen.
