A parallel computational approach for similarity search using Bloom filters
Authors: Chauhan Sachendra Singh , Batra Shalini 
Published: March 2018

AbstractFinding similar items in a large and unstructured dataset is a challenging task in many applications of data science, such as searching, indexing, and retrieval. With the increasing data volume and demand for real time responses, similarity search has gained much consideration. In this paper, a parallel computational approach for similarity search using Bloom filters (PCASSB) has been proposed, which uses Bloom filter for the representation of features of document and comparison with user's query. Query features are stored in integer query array (IQA), an array of integer. The PCASSB, an approximate similarity search technique, has been implemented on graphics processing unit with compute unified device architecture as the programming platform. To compute the similarity score between query and reference dataset, Dice coefficient has been used as a baseline method. The accuracy of the results generated by PCASSB is compared with the baseline method and other state‐of‐the‐art methods. The experimental results show that the proposed technique is quite effective in processing large number of text documents as it takes less computational time.

AbstractBackground and aimAlcoholic liver disease (ALD) represents a frequent indication for liver transplantation (LT). Since 2004, we have adopted a program of multidisciplinary support(MS) to assist patients undergoing LT for ALD. We aimed at analyzing the relapse rate and the risk factors for relapse. The relapse rate was also compared with that of a historical group of patients who underwent transplantation. Their survival rate was also analyzed.Patients and methodsConsecutive patients with ALD transplanted from 2004 were included. The most important demographic, psychosocial, and clinical characteristics known to be associated with alcohol relapse were recorded.ResultsSixty‐nine patients underwent MS: 8.7% presented alcohol relapse. At multivariate analysis female gender (sHR 9.02, 95% CI 1.71‐47.56, P = .009), alcohol withdrawal syndrome (sHR 5.89, 95% CI 1.42‐24.46, P = .015) and a shorter time of MS program before LT (sHR 0.928 per month, 95% CI 0.870‐0.988, P = .021) were identified as independent risk factors for relapse.The rate of alcohol relapse was significantly lower than that of the historical group who did not undergo MS (sHR 0.21, 95% CI: 0.06‐0.68; P = .009).ConclusionThis study shows that a MS program may contribute to alcohol relapse prevention after LT in ALD patients. However, the relevance of this support needs to be confirmed by clinical trials.

IntroductionCytology of giant cell tumour of tendon sheath (GCTTS) is often sufficient to diagnose this lesion and has been previously described in small series. The present study was undertaken to evaluate detailed cytomorphological features and differential diagnostic entities and pitfalls in the diagnosis.MethodsAll the cases of GCTTS reported on FNAC were retrieved from July 2007 to June 2017. The cases were reviewed for various cytomorphological features, which were correlated with follow‐up histopathology wherever available.ResultsA total of 72 cases of GCTTS were retrieved, follow‐up histopathology was available in 20 cases. The common sites of involvement were fingers and palm followed by wrists, elbow, knee, ankle and shoulder. The characteristic cytomorphology consisted of mononuclear cells, multinucleated giant cells and pigment laden macrophages in variable numbers. There were four discordant cases that were confirmed on histopathology as sarcoidosis, melanoma, fibrous histiocytoma and eumycetoma.ConclusionsGCTTS can be confused cytologically with giant cell rich lesions of bone and soft tissue and pigment containing lesions including melanoma. Ladybird cell is a characteristic feature seen in this lesion. Proper clinicoradiological correlation is essential before offering a diagnosis of GCTTS on cytology.

AimIf increased muscle stiffness and contractures in children with cerebral palsy (CP) are related to impaired muscle growth, reduced muscle growth should precede or coincide with increased muscle stiffness during development. Here, we compared the volume of the medial gastrocnemius muscle and the passive (non‐neural) stiffness of the triceps surae musculotendinous unit in typically developing children and children with CP from birth until 4 years of age.MethodForty‐one children with CP and 45 typically developing children were included. Freehand three‐dimensional ultrasound was used to evaluate the volume of the medial gastrocnemius muscle. Biomechanical and electrophysiological measures were used to determine passive and reflex mediated stiffness of the triceps surae musculotendinous unit.ResultsMedial gastrocnemius muscle volume increased with the same rate in typically developing and children with CP until 12 months of age, when a significant smaller rate of growth was observed in children with CP. Passive stiffness of the triceps surae musculotendinous unit showed a linear increase with age in typically developing children. Children with CP older than 27 months showed a significant increase in passive stiffness. Reflex mediated stiffness was only pathologically increased in four children with CP.InterpretationThe deviation of medial gastrocnemius muscle volume, earlier than musculotendinous unit stiffness, is consistent with the hypothesis. The data also point out that muscle atrophy and muscle stiffness already develops within the first 1 to 2 years. This emphasizes the necessity of early interventions to promote lower limb muscle growth in this population.What this paper adds

Medial gastrocnemius muscle growth is reduced in children with cerebral palsy (CP) around 12 months after birth.

Triceps surae musculotendinous unit stiffness is increased in children with CP around 27 months after birth.

Reflex excitability is rarely increased in children with CP.

Reduced muscle growth may be involved in the pathophysiology of contractures.

AbstractAimsTo undertake a feasibility randomized controlled trial of supported self‐management vs treatment as usual in a population of adults with obesity, Type 2 diabetes and an intellectual disability.MethodsWe conducted an individually randomized feasibility trial. Participants were adults aged >18 years with a mild or moderate intellectual disability, living in the community with Type 2 diabetes, on any therapy other than insulin. Participants had mental capacity to consent to research and the intervention. Inclusion criteria included HbA1c > 48 mmol/mol (6.5%), BMI >25 kg/m2, or self‐reported physical activity below national guideline levels. The experimental intervention was standardized supported self‐management delivered by diabetes specialist nurses plus treatment as usual, compared with treatment as usual alone. Feasibility outcomes included: recruitment and retention; intervention acceptability and feasibility; data collection and completeness for physiological state and values for candidate primary outcomes (HbA1c and BMI).ResultsA total of 82 participants (89% of those contacted and eligible) were randomized. All supported self‐management sessions were completed by 35/41 participants (85%); only four completed no sessions. Data on the follow‐up candidate primary outcomes HbA1c and BMI were obtained for 75/82 (91%) and 77/82 participants (94%), respectively. The mean baseline HbA1c was 56±16.5 mmol/mol (7.3±1.5%) and the mean BMI was 34±7.6 kg/m2.ConclusionsAdherence to supported self‐management and willingness to have blood taken for outcome measurement was good. A definitive randomized controlled trial is feasible in this population.(Trial registration: Current Controlled Trials ISRCTN41897033)
Teaching Customer Experience Quality and its Significance in Retail Management: A Role Playing Game using Chinese Puzzle ‘Tangram’
Authors: Paul Rik , Ponnam Abhilash 
Published: March 2018

ABSTRACTServices are intangible in nature. For a marketing educator, it is difficult to illustrate to students the means of creating favorable customer experiences through standard lectures or case studies in a services context, considering this intangibility property. This paper describes a simple role playing game that uses the Chinese puzzle ‘Tangram’ to help students comprehend how customer experiences are shaped within and beyond a service setting. In the game, the class gets divided into two groups, individual customers and furniture retailer teams. The two groups interact with each other in buying and selling modular furniture. At the end of the game, customers share qualitative and quantitative feedback on their retailer experience, and the retailer team which obtains a high score on profitability as well as customer experience quality is declared as the winner. The debriefing session that follows the game lets students share their experiences and key learnings. The game provides the students with a scope to learn and explore the importance of customer experience quality without direct supervision from the instructor. This game requires minimal physical infrastructure. The materials required to conduct this game are easily available in departmental stores, and the monetary cost involved in deploying this game is nominal.
Biphasic effects of THC in memory and cognition
Authors: Calabrese Edward J. , Rubio‐Casillas Alberto 
Published: March 2018

AbstractA generally undesired effect of cannabis smoking is a reversible disruption of short‐term memory induced by delta‐9‐tetrahydrocannabinol (THC), the primary psychoactive component of cannabis. However, this paradigm has been recently challenged by a group of scientists who have shown that THC is also able to improve neurological function in old animals when chronically administered at low concentrations. Moreover, recent studies demonstrated that THC paradoxically promotes hippocampal neurogenesis, prevents neurodegenerative processes occurring in animal models of Alzheimer's disease, protects from inflammation‐induced cognitive damage and restores memory and cognitive function in old mice. With the aim to reconcile these seemingly contradictory facts, this work will show that such paradox can be explained within the framework of hormesis, defined as a biphasic dose‐response.

AbstractIn response to the introduction and spread of the chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) in metropolitan France, including Corsica, the exotic parasitoid Torymus sinensis Kamijo (Hymenoptera: Torymidae) was deliberately introduced in more than 50 locations covering most of the areas of chestnut production. To test the impact of propagule pressure (i.e., the number and size of introductions) on establishment success and post‐release dynamics, the introductions were done according to three experimental modalities: (1) a single introduction of 100 females, (2) two sequential introductions of 50 females, or (3) a single introduction of 1 000 females. Post‐release surveys demonstrated a very high local establishment of T. sinensis, regardless of the introduction modality. Post‐introduction dynamics were found to follow a two‐phase process. First, early dynamics were characterized by an exponential growth of T. sinensis populations without a significant decrease in D. kuriphilus populations. Later, middle‐term dynamics indicated a global decrease in both D. kuriphilus and T. sinensis populations. Quite surprisingly, propagule pressure had a limited effect on post‐introduction dynamics, with a lasting demographic advantage for the largest introductions, but no influence of the number of introductions. Finally, site connectivity had a positive effect on T. sinensis population size, suggesting successful colonization and establishment at a wide spatial scale beyond the introduction sites. In addition, we observed that some T. sinensis exhibited a very short developmental time compared to the majority of the emerged individuals, which may be interpreted as a diversified bet hedging strategy against environmental stochasticity. These findings confirm the strong potential of T. sinensis for successful establishment and sustainable control of the chestnut gall wasp in Europe.
Predator feeding vibrations encourage mosquito larvae to shorten their development and so become smaller adults
Authors: Roberts Derek M. 
Published: March 2018

1. Water‐borne predator kairomones are known to allow mosquito larvae to detect and identify the presence of a specific predator, so that they can deploy defences tailored to that predator. Kairomones, however, have limitations, and detection of specific water‐borne vibrations produced by a predator would allow fine‐tuning of their anti‐predator defences.2. Larvae of the mosquito Culiseta longiareolata have previously been shown to recognise the specific vibration pattern of a feeding dragonfly nymph and respond by altering their feeding behaviour from active bottom‐scraping to a more passive surface filter‐feeding, while other water vibrations did not produce this response. Culex perexiguus larvae also responded, but to a much lesser extent.3. In this study, C. perexiguus larvae responded strongly to dragonfly vibrations by reducing their larval duration from 9.8 to 8.7 days, but this resulted in significantly smaller (and thus probably less successful) adults. However, Culiseta longiareolata larvae did not alter their larval duration in response to dragonfly vibrations.

BackgroundWomen, especially those with low‐socio‐economic status and financial deprivation, are found to be affected by mental illnesses disproportionately. We compared the clinical, functioning and cognitive characteristics between the financially deprived women with first‐episode psychosis and their non‐deprived women counterparts.MethodA cross‐sectional analysis of consecutively recruited first‐episode psychosis women patients was conducted. A total of 93 financially deprived women patients and 105 non‐deprived women patients aged 25 to 55 years were compared in terms of demographic, premorbid and help‐seeking characteristics, baseline clinical characteristics, baseline functioning and baseline cognitive functioning.ResultsFinancially deprived women were older (P= .005), had received less education (P= .001), more likely to live alone (P< .001) and with a higher proportion of immigrants (P= .001). Whereas there was no significant difference found in duration of untreated psychosis, deprived women had more severe depressive symptoms (P= .021) and more severe negative symptoms, in terms of avolition‐apathy (P= .003) and anhedonia‐asociality (P= .008). They also perform worse in social and occupational functioning (P= .002) and a range of cognitive abilities.ConclusionsNearly half of the adult female patients with first‐episode psychosis in Hong Kong encountered persistent financially difficulties. The fact that they suffer from more severe symptoms and worsened functioning and cognitive abilities at an early stage of illness shows that this subgroup of patients warrant assistance and attention.

Background and purposeEducational intervention has proved to be effective in reducing drug abuse in uncomplicated medication‐overuse headache (MOH). This ancillary of the SAMOHA multicentre study aimed to assess any differences in phenotypic characteristics, type and amount of drugs overused, and comorbidities between patients with MOH who responded to simple advice and those who did not.MethodsDemographic and clinical headache data of the last 3 months before enrollment of patients were collected and patients were then asked to fill out a daily headache diary for 4 weeks. Patients were then divided into two subgroups, i.e. those with confirmed MOH continued in the study [randomized (R) group], whereas those who did not still show any features of MOH dropped out of the study.ResultsA total of 88 (67.7%) patients still met the inclusion criteria after the baseline 4 weeks (R group). Conversely, 42 (32.3%) patients dropped out of the study. A detailed analysis of those who dropped out revealed that only 34 were not randomized at visit 2 because they no longer satisfied the inclusion criteria for MOH [screening failures (SF) group]. The SF group was significantly younger and had fewer years of migraine history than the R group. Moreover, the SF group had a significantly shorter history of chronicity compared with the R group.ConclusionsOur findings suggest that in MOH trials, after an educational session, an observational period is needed in order to confirm the diagnosis of MOH and to avoid overestimation of the effect of other treatments used to manage MOH. Future research should focus mainly on those patients with MOH who do not respond to simple advice and with unsuccessful withdrawal.
Comparative effects of ammonium, nitrate and urea on growth and photosynthetic efficiency of three bloom‐forming cyanobacteria
Authors: Erratt Kevin J. , Creed Irena F. , Trick Charles G. 
Published: March 2018

Abstract

Urea‐based fertilisers have grown in popularity over the past half‐century and are now the dominant nitrogen (N) form applied to agricultural landscapes. The widespread use of urea fertilisers has favoured its export to local waterways, and urea pollution may be contributing to the propagation and maintenance of cyanobacteria harmful algal blooms in fresh waters. The relative success of cyanobacteria in response to urea and inorganic N additions was studied to understand whether the recent changes in the magnitude and composition of N loading have created a scenario that now favours the dominance of cyanobacteria in fresh waters.

Growth and photosynthetic efficiency of three bloom‐forming freshwater cyanobacteria (Microcystis, Dolichospermum and Synechococcus) grown on nitrate (), ammonium () and urea (CO(NH2)2) as the sole N form were monitored. We hypothesised that N substrates that require the lowest energetic investment or offer the highest energetic return would favour optimal growth and photosynthetic performance. We predicted that urea would result in higher cellular growth and pigment production relative to or , as urea provides twice the amount N and an additional carbon (C) source making it more energetically efficient.

Cyanobacteria biomass was not significantly enhanced on urea relative to inorganic N forms. Growth on urea was matched by for all species, whereas growth on was halved compared urea or . However, cyanobacteria cells had higher pigment concentrations when grown on urea relative to inorganic N sources. These findings suggest that the additional nutrient building blocks supplied from the hydrolysis of urea were not directed towards active growth, but rather accumulated in secondary pools to increase production of N‐rich compounds, such as pigments.

Although urea did not influence cyanobacteria quantity “(i.e. biomass)” compared to inorganic N sources, it produced higher “quality” cells by enhancing pigment synthesis and potentially giving cyanobacteria a competitive advantage in light‐limiting conditions. Furthermore, when supplied in excess, cyanobacteria rapidly consumed urea in excess of their biosynthetic requirements suggesting a form of urea “gluttony.” These results demonstrate the importance of N speciation on cyanobacteria physiological responses and reinforce the emerging links between urea and cyanobacteria harmful algal blooms in inland waters.

AbstractWetlands are the largest source of methane (CH4) globally, yet our understanding of how process‐level controls scale to ecosystem fluxes remains limited. It is particularly uncertain how variable soil properties influence ecosystem CH4 emissions on annual time scales. We measured ecosystem carbon dioxide (CO2) and CH4 fluxes by eddy covariance from two wetlands recently restored on peat and alluvium soils within the Sacramento–San Joaquin Delta of California. Annual CH4 fluxes from the alluvium wetland were significantly lower than the peat site for multiple years following restoration, but these differences were not explained by variation in dominant climate drivers or productivity across wetlands. Soil iron (Fe) concentrations were significantly higher in alluvium soils, and alluvium CH4 fluxes were decoupled from plant processes compared with the peat site, as expected when Fe reduction inhibits CH4 production in the rhizosphere. Soil carbon content and CO2 uptake rates did not vary across wetlands and, thus, could also be ruled out as drivers of initial CH4 flux differences. Differences in wetland CH4 fluxes across soil types were transient; alluvium wetland fluxes were similar to peat wetland fluxes 3 years after restoration. Changing alluvium CH4 emissions with time could not be explained by an empirical model based on dominant CH4 flux biophysical drivers, suggesting that other factors, not measured by our eddy covariance towers, were responsible for these changes. Recently accreted alluvium soils were less acidic and contained more reduced Fe compared with the pre‐restoration parent soils, suggesting that CH4 emissions increased as conditions became more favorable to methanogenesis within wetland sediments. This study suggests that alluvium soil properties, likely Fe content, are capable of inhibiting ecosystem‐scale wetland CH4 flux, but these effects appear to be transient without continued input of alluvium to wetland sediments.
