Paraplegia Caused by Undiagnosed Metastatic Spinal Tumour in a Patient Receiving Epidural Anaesthesia

The pre-existing spinal pathologies may increase the incidence of severe neurological complications, (1, 2). Here, we report a patient without obvious symptom of spinal cord or root compression previously who developed paraplegia early following epidural anaesthesia, which was possibly caused by an undiagnosed metastatic spinal tumour. A 68-year old, 70kg, 178cm, ASA II man was scheduled for rectal carcinectomy. No obvious symptoms of spinal cord or root compression, such as back pain, numbness in the lower-extremity, were presented. An epidural catheter was uneventfully inserted at the L1-2 interspace, and a test dose of 4 mL 2% lidocaine and 5 mL 0.5% ropivacaine were injected, respectively, after negative aspiration of cerebrospinal fluid (CSF) or blood, the initial sensory block level was at T11-L2. No discomfort was reported by the patient. The general anaesthesia was induced by intravenous administration of sufentanil 20 μg, propofol 100 mg and rocuronium 50 mg. The operation lasted for about 160 minutes and the haemodynamic parameters were stable. The patient complained of numbness and weakness in both lower-extremities at about 36 hours postoperatively. The symptoms progressed, physical examination demonstrated the ebbing pain and tactile sensation extended to sensory area below T10, and muscle power of both lower limbs were 0/5, knee jerk reflex and Babinski sign were not elicited at 72 hours postoperatively. The laboratory coagulation tests were in normal ranges. The emergency total spine magnetic resonance imaging (MRI) demonstrated obvious bone destruction at T89 and L1 vertebral bodies, and soft-tissue mass at T8-9 level was revealed, the mass with clear edge appeared as low signal intensity on T1 and T2-weighted images and high signal intensity on Stir sequences, the mass intruded into the vertebral canal and compressed the spinal cord. The pre-existed metastatic tumour of the thoracic spine was diagnosed (Figs. 1, 2). The symptoms were not relieved after medication, and the patient rejected emergency laminectomy or radiotherapy because of financial difficulty and was discharged at the 10th day, postoperatively. Since Nicholson et al, first reported paralysis caused by a metastatic spinal tumour after continuous spinal anaesthesia in 1946 (6), several mechanisms have been speculated. Obstruction of CSF flow by a space-occupying lesion above the puncture site may influence the dilution of the injected material, which may increase both the concentration and neurotoxicity of local anaesthetic. The second hypothesis is about “spinal coning” with an incidence of 14%–26%, which results from compartmental pressure differences (7, 8). The lumbar puncture exacerbates the dangerous pressure differentials above and below the spinal tumour and can induce neurologic complications (8). For epidural anaesthesia in this case, the
Study of Turbulent Mixing in a Channel Flow by Numerical Tracking of Material Surfaces

A property of turbulent mixing, i.e. stretching of material surfaces, in a wall-bounded flow is examined through the direct numerical simulation (DNS) of a turbulent channel flow. Statistics of a stretching rate and a fractal dimension on the material surface are presented. A series of DNS has been performed with various initial conditions of the surfaces in order to discuss the influence of the wall on mixing. The stretching rate A, normalized by the Kolmogorov time , of a material surface in the core region is comparable to that in homogeneous isotropic turbulence. However the asymptotic value for sufficiently extended surfaces is A =0.1( min) corresponding to one-third of the value (0.3 ) for the homogeneous turbulence reported by Goto & Kida [J. Fluid Mech. 586, 59 (2007)]. The fractal dimension of the surface investigated here through the box-counting procedure increases with time until it attains the asymptotic value of 2.39 ± 0.03.
FUSÃO DE DADOS DE SENSORES PARA ESTIMAÇÃO DE POSIÇÃO E ORIENTAÇÃO DO APM AEROMÓVEL

Abstract— APMs (Automated People Movers) are light vehicles used to move people in urban areas, implementing a concept similar to a horizontal elevator. The Aeromóvel system is an APM system where the vehicle is moved by air flow and requires its position to be known with a precision better then 10cm. In order to ensure such a precision, this papers proposes a data fusion system, integrating data from different sensors by using an extended Kalman filter. The system uses data from optical encoders in the train wheels and GPS data to estimate the vehicle position and orientation. Since the vehicle has two trucks, with four independent wheels each one, the proposed method groups the wheels in pairs. Each pair of wheels is used to compute an estimate of position and orientation that is fused with estimations from other pairs of wheels and the GPS receiver. Simulated results are presented to show the effectiveness of the approach.
Income Intervention Quick Scan : Climate Change Adaptation

UK This quick scan, commissioned by the Farmer Income Lab, is part of a wider research effort looking at, “What are the most effective actions that lead buyers can take to enable smallholder farmers in global supply chains to meaningfully increase their incomes? ”. The quick scan provides an overview of the publicly available evidence on the impact of climate change adaptation interventions have had on raising farmer income. Such subsidies have had little positive effect on farmer income, are not notably beneficial for women nor is this effect long-term. They have been applied at large scale. This quick scan is part of a series of 16, contributing to a synthesis report “What Works to Raise Farmer’s Income: a Landscape Review”.
A sub-1-dB NF±2.3-kV ESD-protected 900-MHz CMOS LNA

A sub-1-dB noise figure HBM ESD-protected [-3 kV, 2.3 kV] low noise amplifier (LNA) has been integrated in a 0.35-/spl mu/m RF CMOS process with on-chip inductors. The sensitivity of the LNA performances to the spread of parasitics associated with package and bondwire has been attenuated by using an inductive on-chip source degeneration. At 920 MHz and P/sub dc/=8.6 mW, the LNA features: noise figure NF=1 dB, input return loss=-8.5 dB, output return loss=-27 dB, power gain G/sub p/=13 dB, input IIP3=-1.5 dBm. At a power dissipation of 5 mW and 17.6 mW, a NF respectively equal to 1.2 dB and 0.85 dB is measured. The CMOS LNA takes 12 pins of a TQFP48 package, an area of 1.0/spl times/0.66 mm/sup 2/ (bondwire pads excluded) and it is the first HBM ESD-protected [-3 kV, 2.3 kV] CMOS LNA to break the 1-dB NF barrier.
Quick Guidelines to Reviewing your Proof PDF below 1

The feeding behavior of the cosmopolitan cold-water coral (CWC) Desmophyllum dianthus (Cnidaria: Scleractinia) is still poorly known. Its usual deep distribution restricts direct observations, and manipulative experiments are so far limited to prey that do not occur in CWC natural habitat. During a series of replicated incubations, we assessed the functional response of this coral feeding on a medium-sized copepod (Calanoides patagoniensis) and a large euphausiid (Euphausia vallentini). Corals showed a Type I functional response, where feeding rate increased linearly with prey abundance, as predicted for a tentaculate passive suspension feeder. No significant differences in feeding were found between prey items, and corals were able to attain a maximum feeding rate of 10.99 mg C h, which represents an ingestion of the 11.4% of the coral carbon biomass per hour. These findings suggest that D. dianthus is a generalist zooplankton predator capable of exploiting dense aggregations of zooplankton over a wide prey size-range. Subjects Ecology, Marine Biology
Electricity through Train

This paper aims at production of electricity by using the concept of the rotation of wind turbine due to the wind caused by the moving train and also by using an electrical power generation system. As anyone living near railway tracks will tell you, speeding trains generate quite a bit of wind as they whoosh past. The idea is to design a wind turbine that can be installed between the sleepers on a track, and as the train passes overhead, the wind drives a turbine to generate electricity. This device could be placed along railway or subway lines, and make good use of an otherwise wasted resource. An electrical power generation system comprises a variable capacitor and a power source. The power source is used in the form of a generator to prime the variable capacitor that effectively multiplies the priming energy of the power source by extracting energy from the passing vehicle. By alternately priming the variable capacitor using charge from the power source and discharging it at a later time in a cyclic manner to change the capacitance, a significantly large amount of electrical energy is produced due to change in capacitance.
Use of Combined Topic Models in Unsupervised Domain Adaptation for Word Sense Disambiguation

Topic models can be used in an unsupervised domain adaptation for Word Sense Disambiguation (WSD). In the domain adaptation task, three types of topic models are available: (1) a topic model constructed from the source domain corpus: (2) a topic model constructed from the target domain corpus, and (3) a topic model constructed from both domains. Basically, three topic features made from each topic model are added to the normal feature used for WSD. By using the extended features, SVM learns and solves WSD. However, the topic features constructed from source domain have weights describing the similarity between the source corpus and the entire corpus because the topic features made from the source domain can reduce the accuracy of WSD. In six transitions of domain adaptation using three domains, we conducted experiments by varying the combination of topic features, and show the effectiveness of the proposed method.
THE CUES FOR RHETORICAL RELATIONS IN RUSSIAN : “ CAUSE — EFFECT ” RELATION IN RUSSIAN RHETORICAL STRUCTURE

The purpose of the paper is to investigate cues signalling the relations between discourse units in Russian. Building a lexicon of discourse connectives is an indispensable subtask in many discourse parsing applications as well as an essential issue in theoretical researches of text coherence. In order to develop such a resource for Russian, we have conducted a corpus-based study of discourse connectives that were manually extracted from the Russian Rhetorical Structure Treebank (Ru-RSTreebank). The Treebank includes 79 texts annotated within the RST framework (Mann, Thompson 1988). In order to provide a deeper analysis of connectives in Russian, we focus on causal relations only, namely, the ‘Cause-Effect’ relation. Some of the connectives (primary connectives) are enumerated in grammars and dictionaries. They primarily mark the intra-sentential relations. However, there is an expansive class of less grammaticalized items (secondary connectives) that have received less attention till now. Some of them are based on content words (e.g. по причине ‘for the cause’). Secondary connectives often serve as linking devices for inter-sentential relations. We suggest a scheme for connectives annotation for Russian. We specify the basic patterns that can be used for less-grammaticalized connectives mining in an unannotated corpus. Besides, we provide the comparison of two classes of connectives (primary vs. secondary ones). Our research
Impact of Solid Core PCF Structure on SERS Performance

The combination of photonic crystal fiber and surface enhanced Raman scattering sensor constructs photonic crystal fiber surface enhanced Raman scattering sensor, and this novel sensor has been given broad attention. The performance of this sensor will be affected by photonic crystal fiber’s structure, substrates of surface enhanced Raman scattering and so on. To develop photonic crystal fiber surface enhanced Raman scattering sensor’s huge action, the novel structure of solid core photonic crystal fiber was designed. On the base of ensuring fundamental transmission, increasing mode area is the most important. By numeral simulation, the designed solid core photonic crystal fiber has large mode area relative to other structures solid core photonic crystal fiber. So this structure photonic crystal fiber can ensure better surface enhanced Raman scattering performance
Expressing Parallelism and Timing in Embedded Real-Time Applications

We present a domain specific language for hard real-time applications. It uses the concept of single variable assignment and allows the definition of timing constraints. The language has been designed to express the parallelism in real-time control system applications. The included editor runs static analysis and shows the degree of parallelism on the fly. The proposed language is part of an execution framework that is used to evaluate patterns for parallel programming.
A Survey of Semantic Technology and Ontology for e-Learning

Semantic technology and ontology (STO) are being investigated in various areas. In the elearning context, many studies have used STO to address problems such as the interoperability of learning objects (LOs), modeling and enriching learning resources, and personalizing educational content recommendations. This study systematically reviewed research on STO in e-learning systems from 2008 to 2018. The review was guided by three research questions: RQ1: “What are the major uses of ontology in e-learning systems? ” RQ2: “What is the state of the art in educational ontology? ” and RQ3: “What are the various applications of STO-based learning systems? ” Based on 134 papers, we analyzed six types of ontology use and five aspects of educational ontology, as well as e-learning systems that use semantic approaches. The observations obtained from this survey can benefit researchers in this area and help guide future research.
How Lego Serious Play supports team building through the creative co-production

This case study paper will describe the process and underlying theory behind the use of Lego Serious Play (LSP) being used to develop a shared vision and real time strategy for the Translating Evidence to Enhance Maternal-newborn care: Knowledge Translation (TEEM-KT) team. LSP draws on a range of theories around reflection, externalising thoughts and making tangible alongside the actual building of metaphors as a means of sharing and developing complex ideas. These theories will be discussed further in the paper in light of the authors previous work around knowledge mobilization and particularly creative practices in knowledge mobilization. In the case study described, there were 20 participants including the team lead and Research Fellow and the session was delivered by two LSP trained facilitators. The methods were drawn from the LSP canon with preliminary skills building followed by a series of questions prompting participants to build and share. This process explored personal then collective perspectives about the current team then a vision for 3 years in the future. Short evaluation questionnaires were filled in before and after the session by all participants, asking about expectations and then how the workshop had addressed those expectations. Other results were in the form of the individual and shared models that were created and described by the teams. Whilst LSP has been used extensively in the Business world, the authors feel it has much to offer in the world of health, not only in team and strategy building but in the broader endeavours of knowledge mobilization. It is an example of creative co-production and addresses and evidences many of the challenges of coproduction identified in the health literature.

Insights on the use of dolphins (boto, Inia geoffrensis and tucuxi, Sotalia fluviatilis) for bait in the piracatinga (Calophysus macropterus) fishery in the western Brazilian Amazon

In the Amazon Basin, the use of the pink dolphin or boto (Inia geoffrensis) for bait in the piracatinga (Calophysus macropterus) fishery was first detected in the year 2000. Since then, this artisanal fishery has become more prevalent as it requires only a few hours of work per night and provides immediate cash earnings. It is thus an attractive addition to (or replacement for) traditional fishing. Previous reports have noted the use of botos as bait, but stated that the most common bait used are caimans (Melanosuchus niger, Caiman crocodilus). Estimates of the number of dolphins killed based on fish landings have been proposed and an apparent decrease in sighting/survival of an artificially-marked boto population was observed. Although stocks/population estimates, trends and actual numbers of hunted dolphins are unknown, the conservation impacts of this activity are of concern. Between October 2010 and November 2011, research was conducted within an area with serious conflicts between dolphins and fishermen as well as intense fishing for piracatinga, i.e. in the lower Japurá River, on the border with the Mamirauá and Amanã Sustainable Development Reserves, where both boto and tucuxi (Sotalia fluviatilis) are used for bait. One-hundred and fifty-seven monitoring surveys were carried out in eight key communities, confirming 114 piracatinga fishing events through direct monitoring and incognito surveys of fishing gear (gaiolas). Empirical evidence of the activity in gaiolas comprised pieces of bait, carcass remains, piracatinga provoked vomits and dolphin fished carcasses. Of those, 31.2% (n = 35) involved cetacean bait (91.4% I. geoffrensis, 8.58% S. fluviatilis), 68.7% (n = 77) caiman bait (96% M. niger, 4% C. crocodilus), and two fishing events used both types. These percentages may be higher/lower in other areas within and outside the Reserves. Given the increasing trend of the piracatinga fishery, the authors believe that precautionary measures for the conservation of Amazonian dolphins are urgently needed. Development of practical short-term solutions (e.g. offal-baited fish traps) and multispecies management together with law enforcement, incentives and educational programmes could allow the future transition of riverine communities from the piracatinga fishery to sustainable, higher income activities.

Concentration of Polyunsaturated Fatty Acid of Rice Bran Oil by Urea Complexation – A Response Surface Approach

The processes for the concentration of fatty acids in the production of polyunsaturated fatty acids (PUFA) have become very important because of the beneficial properties of these substances to human health and in functional foods. Optimization of the concentrating conditions of Polyunsaturated fatty acid (PUFA) extracted from rice bran oil was studied to obtain maximum concentration. The crude rice bran oil was extracted from the KDML105 rice bran variety, and the extracted oil was used as fresh crude oil. The PUFA was concentrated by the urea complexation method. A hexagonal rotatable design was applied to examine the effects of crystallization temperature and urea-to-fatty acid ratio on the total content of PUFA (Y). We investigated the changes of different crystallization temperatures (-10, 0 and 10C) and urea-to-fatty acid ratios (2:1, 3:1 and 4:1, w/w) on the total PUFA content. The second order polynomial regression model for response was employed to generate the response surfaces. Under the optimum conditions of -7.2°C and a urea-to-fatty acid ratio of 2.91 (w/w), the total concentration of PUFA could be increased by up to 77.48% was obtained.
Multiple Open Services in a Structural Computing Environment

This position paper argues that the structural computing workshop should cover more research ground than just structural computing systems. The ongoing research thread on multiple open service systems is close related to the structural computing systems research thread, and as such is very relevant to the workshop. The paper starts with a historical perspective on hypermedia infrastructure research as an attempt to place current research on structural computing systems and multiple open service systems in context. The remainder of the paper focuses on multiple open service systems. The basic ideas, goals and characteristics of multiple open service systems are described.
