Abstract

Introduction: Compound fluid filaments appear in many applications, e.g., drug delivery and processing or microfluidic systems. This paper focuses on the numerical simulation of an incompressible, immiscible, and Newtonian fluid for the contraction process of a fluid compound filament by solving the Navier-Stokes equations. The front-tracking method is used to solve this problem, which uses connected segments (Lagrangian grid) that move on a fixed grid (Eulerian grid) to represent the interface between the liquids. Methods: The interface points are advected by the velocity interpolated from those of the fixed grid using the area weighting function. The coordinates of the interface points are used to construct the indicators specifying the different fluids and compute the interfacial tension force. Results: The simulation results show that under the effects of the interfacial tension, the capsuleshaped filament can transform into a spherical compound droplet (i.e., non-breakup) or can break up into smaller spherical compound and simple droplets (i.e., breakup). When the density ratio of the outer to middle fluids increases, the filament changes from non-breakup to breakup upon contraction. Conclusion: Increasing the density ratio enhances the breakup of the compound filament during contraction. The breakup is also promoted by increasing the initial length of the filament.

Abstract

This paper presents a new characterization of subjective possibility theory. Anscombe and Aumann 1 pioneered a multiple-variable approach to characterize the subjective probability on the basis of its relationship with objective probability. We generalize the Anscombe-Aumann approach to define subjective possibility theory. To characterize the uncertainty of the variable of interest (H) we consider its relationship with a variable of probability and a variable of ignorance. Our axiomatization assumes that the preference over the acts contingent on the outcomes of the variables is a weak order and satisfies a monotonicity property; the preference over probabilistic lotteries is represented by linear utility; and the preference over acts under ignorance by a recently developed ?-anchor utility theory. We show that if H and the variable of ignorance are completely reversible in Anscombe-Aumann's sense and H and the variable of probability are partially reversible then the uncertainty of H must obey the laws of possibility theory. We outline a framework to manage heterogeneous uncertainty that includes probability, possibility and ignorance in decision making.

Abstract

Due to the variability in characteristics of audio scenes, some scenes can naturally be recognized earlier than others. In this work, rather than using equal-length snippets for all scene categories, as is common in the literature, we study to which temporal extent an audio scene can be reliably recognized given state-of-the-art models. Moreover, as model fusion with deep network ensemble is prevalent in audio scene classification, we further study whether, and if so, when model fusion is necessary for this task. To achieve these goals, we employ two single-network systems relying on a convolutional neural network and a recurrent neural network for classification as well as early fusion and late fusion of these networks. Experimental results on the LITIS-Rouen dataset show that some scenes can be reliably recognized with a few seconds while other scenes require significantly longer durations. In addition, model fusion is shown to be the most beneficial when the signal length is short., Accepted to 2019 AES Conference on Audio Forensics

Abstract

Precision measurements by the Alpha Magnetic Spectrometer (AMS) on the International Space Station of 3He and 4He fluxes are presented. The measurements are based on 100 million 4He nuclei in the rigidity range from 2.1 to 21 GV and 18 million 3He from 1.9 to 15 GV collected from May 2011 to November 2017. We observed that the 3He and 4He fluxes exhibit nearly identical variations with time. The relative magnitude of the variations decreases with increasing rigidity. The rigidity dependence of the 3He/4He flux ratio is measured for the first time. Below 4 GV, the 3He/4He flux ratio was found to have a significant long-term time dependence. Above 4 GV, the 3He/4He flux ratio was found to be time independent, and its rigidity dependence is well described by a single power law ∝RΔ with Δ=−0.294±0.004. Unexpectedly, this value is in agreement with the B/O and B/C spectral indices at high energies.

Abstract

Background and Aims: In developed countries, women appear to receive evidence-based care less often than men. Whether there are sex differences in stroke care and outcomes in developing countries is uncertain. Method(s):We included consecutive strokes admitted to the 115 People's Hospital - a major metropolitan public hospital in Vietnam during Jun 2017-Mar 2018. The data were collected using the REgistry of Stroke Care Quality (RES-Q). Baseline characteristics, clinical care provided in hospital (e.g. stroke unit access, thrombolysis), and outcomes at discharge (mortality and functional outcome assessed by the ability to walk without assistance) were compared between sexes. Result(s): Data were available for 6,601 strokes (44% women, 81% ischemic stroke). Compared to men, women were older (mean age 65 vs 60 years), less often current smokers (16% vs 63%) and had more atrial fibrillation detected by screening (12% vs men 8%; all p values<0.001). More women had assessment for rehabilitation needs <=72 hours (35% vs 31%, p=0.022) or carotid investigation <=7 days after hospital admission (4% vs 6%, p=0.041). There were no differences in receipt of other clinical care between sexes (Figure). Women had somewhat greater inhospital mortality 3.4% vs 2.7%; p=0.139) and lesser ability to walk on discharge (47% vs 44%; p=0.031) than men, but the differences were small and not influenced by the clinical care received. Conclusion(s): Generally, men and women with acute stroke received equivalent hospital care. Outcomes at discharge did not differ by sex. Nonetheless, uncertainty exists over the sex differences in long-term outcomes, requiring longer-term follow-ups. (Figure Presented).

Abstract

Background and Aims: We aimed to examine sex differences in disease profiles, management, and survival at 1 and 5 years after ischemic stroke (IS) among people with atrial fibrillation (AF). Method(s): Individual participant data on covariates and survival were obtained from 9 population-based stroke incidence studies conducted in Australasia, Europe, and South America (1993-2014). The presence of AF at the time of stroke onset was self-reported (2 studies) or confirmed by ECG/medical records (7 studies). The mortality rate ratio (MRR) between women and men was estimated using Poisson modelling. Study-specific unadjusted and adjusted MRRs were combined using random-effects meta-analysis. Result(s): There were 8645 participants (mean age: 72.6; 51.8% women). The pooled AF prevalence was 26.6% in women and 20.8% in men. Among the 1862 IS patients with AF, women were older than men. There were no significant sex differences in prescription of antihypertensive, antiplatelet and anticoagulation agents at admission. Crude pooled 1-year mortality was greater for women (30.4%) than men (24.5%) (1- year MRR 1.24; 95% CI, 1.01-1.51; 5-year MRR 1.28; 0.98-1.66). However, the sex difference was greatly attenuated after accounting for age, pre-stroke function and stroke severity (1-year MRR 1.09; 95% CI 0.97-1.22; 5-year MRR 0.81; 0.60-1.09). Conclusion(s): AF was more prevalent after IS among women than men. Among those with AF and IS, stroke management was similar irrespective of sex. Greater mortality in women with AF after IS was mostly attributable to pre-stroke factors. The data are very encouraging in that sex differences in management and outcomes were absent. .

Abstract

In this work, 31.4 wt.% Ni/SBA-15 (Ni/SBA-15) nonpromoted and alkalized with ammonia solution and by MgO promoter catalysts were prepared and used for combined steam and CO2 reforming of CH4 (bireforming). Effect of concentration of ammonia solution (NH3(aq)) (10–25 vol.%) and Mg content (3–12 wt.%) on the properties of the Ni/SBA-15 catalysts was investigated by low-angle and powder X-ray diffraction (XRD), N2-BET isothermal adsorption, SEM, TEM, EDS mapping, H2-TPR, and CO2-TPD methods. The performance of the catalysts in bireforming was assessed in the temperature range of 550–800°C. The enhancement of dispersion of NiO particles, reducibility, and basicity of alkalized Ni/SBA-15 catalysts were responsible for improving the catalytic performance of this catalyst. The results revealed that the Ni/SBA-15 treated with 15-25% NH3(aq) solution and promoted with 3-9% Mg exhibited high activity for CH4 conversion. Meanwhile, Ni6Mg/SBA-15 showed the highest CO2 conversion. Among tested catalysts, Ni/SBA-15-20NH3 and Ni9Mg/SBA-15 samples had an almost equal activity with a CH4 conversion of nearly 97% and a CO2 conversion of about 84% at 700°C thanks to its moderate affinity with both CO2 and CH4. However, the H2/CO ratio of the product mixture remained at 2.02 on the Ni/SBA-15-20NH3 catalyst and almost 1 on the Ni9Mg/SBA-15 sample. These results might be related to the fact that the alkalization of the Ni/SBA-15 catalyst by NH3(aq) solution had an advantage over using MgO because side reactions were unlikely to occur.

Abstract

In the paper, the model and method of synthesizing quasi-time optimal control laws for Two Degree of Freedom (2-DOF) Robotic Arms are presented. 2-DOF Robotic Arms is a non-linear MIMO System with large nonlinear characteristics and uncertain parameters. In this design method, it is necessary to convert the MIMO system to the SISO system, in which each SISO system is guaranteed in Jordan form, followed by using the conversion system in the form of quasi-time optimal equation. By this method, the control law ensures a stable global Robotic Arm. In addition, the control law also ensures that the Robotic Arm System has a quick response of time, but also ensures a stable and robust system when changing parameters and impact noise. The simulation results on the 2-DOF Robotic Arm show the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Abstract

In the paper, it is presented about the design of the quasi-time optimal control law for Ball and Beam system when the control signal is limited. Impact signal limits are characteristic of real physical systems, so when designing embedded control systems this is an important factor to consider. In this design method, the transformation from the equations of object system to equations with limited control signals is made using extra variables. Proceed to synthesize the new control laws on the new system by the quasi-time optimal control. By the proposed synthesizing method, the control law ensures that the embedded control system works stably and the system works quickly in terms of time. Simulation and experimental results show the effectiveness of the proposed design. [ABSTRACT FROM AUTHOR]

Abstract

Purpose Speed of bloodstream infection diagnosis is vital to reduce morbidity and mortality. Whole genome sequencing (WGS) performed directly from liquid blood culture could provide single-assay species and antibiotic susceptibility prediction; however, high inhibitor and human cell/DNA concentrations limit pathogen recovery. We develop a method for the preparation of bacterial DNA for WGS-based diagnostics direct from liquid blood culture. Methodology We evaluate three commercial DNA extraction kits: BiOstic Bacteraemia, Amplex Hyplex and MolYsis Plus. Differential centrifugation, filtration, selective lysis and solid-phase reversible immobilization bead clean-up are tested to improve human cells/DNA and inhibitor removal. Using WGS (Illumina/MinION), we assess human DNA removal, pathogen recovery, and predict species and antibiotic susceptibility inpositive blood cultures of 44 Gram-negative and 54 Staphylococcus species. Results/Key findings BiOstic kit extractions yield the greatest mean DNA concentration, 94–301 ng µl−1, versus 0–2.5 ng µl−1 using Amplex and MolYsis kits. However, we note higher levels of inhibition (260/280 ratio 0.9–2.1) and human DNA (0.0–4.4×106 copies) in BiOstic extracts. Differential centrifugation (2000 g , 1 min) prior to BiOstic extraction reduces human DNA by 63–89 % with selective lysis minimizing by a further 62 %. Post-extraction bead clean-up lowers inhibition. Overall, 67 % of sequenced samples (Illumina MiSeq) contain 93 % concordance between WGS-based species and susceptibility predictions and clinical diagnosis. If >60 % of sequencing reads are human (7/98 samples) susceptibility prediction becomes compromised. Novel MinION-based WGS (n=9) currently gives rapid species identification but not susceptibility prediction. Conclusion Our method for DNA preparation allows WGS-based diagnosis direct from blood culture bottles, providing species and antibiotic susceptibility prediction in a single assay.

Abstract

In this paper, we present a simple and parameter-efficient drop-in module for one-stage object detectors like SSD when learning from scratch (i.e., without pre-trained models). We call our module GFR (Gated Feature Reuse), which exhibits two main advantages. First, we introduce a novel gate-controlled prediction strategy enabled by Squeeze-and-Excitation to adaptively enhance or attenuate supervision at different scales based on the input object size. As a result, our model is more effective in detecting diverse sizes of objects. Second, we propose a feature-pyramids structure to squeeze rich spatial and semantic features into a single prediction layer, which strengthens feature representation and reduces the number of parameters to learn. We apply the proposed structure on DSOD and SSD detection frameworks, and evaluate the performance on PASCAL VOC 2007, 2012 and COCO datasets. With fewer model parameters, GFR-DSOD outperforms the baseline DSOD by 1.4%, 1.1%, 1.7% and 0.6%, respectively. GFR-SSD also outperforms the original SSD and SSD with dense prediction by 3.6% and 2.8% on VOC 2007 dataset. Code is available at: https://github.com/szq0214/GFR-DSOD ., Accepted in BMVC 2019.

Abstract

Purpose of the study This study provides benchmarks for likelihood, number of days until, and sequence of functional decline and recovery. Design and methods We analyzed activities of daily living (ADLs) of 296,051 residents in Veteran Affairs nursing homes between January 1, 2000 and October 9, 2012. ADLs were extracted from standard minimum data set assessments. Because of significant overlap between short- and long-stay residents, we did not distinguish between these populations. Twenty-five combinations of ADL deficits described the experience of 84.3% of all residents. A network model described transitions among these 25 combinations. The network was used to calculate the shortest, longest, and maximum likelihood paths using backward induction methodology. Longitudinal data were used to derive a Bayesian network that preserved the sequence of occurrence of 9 ADL deficits. Results The majority of residents (57%) followed 4 pathways in loss of function. The most likely sequence, in order of occurrence, was bathing, grooming, walking, dressing, toileting, bowel continence, urinary continence, transferring, and feeding. The other three paths occurred with reversals in the order of dressing/toileting and bowel/urinary continence. ADL impairments persisted without any change for an average of 164 days (SD = 62). Residents recovered partially or completely from a single impairment in 57% of cases over an average of 119 days (SD = 41). Recovery rates declined as residents developed more than 4 impairments. Implications Recovery of deficits among those studied followed a relatively predictable path, and although more than half recovered from a single functional deficit, recovery exceeded 100 days suggesting time to recover often occurs over many months.

Abstract

Sos-1 and Sos-2 are ubiquitously expressed Ras-guanine exchange factors involved in Erk-MAP kinase pathway activation. Using mice lacking genes encoding Sos-1 and Sos-2, we evaluated the role of these proteins in peripheral T-cell signaling and function. Our results confirmed that TCR-mediated Erk activation in peripheral CD4(+) T cells does not depend on Sos-1 and Sos-2, although IL-2-mediated Erk activation does. Unexpectedly, however, we show an increase in AKT phosphorylation in Sos-1/2dKO CD4(+) T cells upon TCR and IL-2 stimulation. Activation of AKT was likely a consequence of increased recruitment of PI3K to Grb2 upon TCR and/or IL-2 stimulation in Sos-1/2dKO CD4(+) T cells. The increased activity of the PI3K/AKT pathway led to downregulation of the surface receptor CD62L in Sos-1/2dKO T cells and a subsequent impairment in T-cell migration.

Abstract

Background and purpose: Women may receive stroke care less often than men. We examined the contribution of clinical care on sex differences and health‐related quality of life (HRQoL) after stroke. Methods: We included first‐ever strokes registered in the Australian Stroke Clinical Registry (2010–2014) with HRQoL assessed between 90 and 180 days after onset (EQ‐5D‐3L instrument) that were linked to hospital administrative data (up to 2013). Study factors included sociodemographics, comorbidities, walking ability on admission (stroke severity proxy) and clinical care (e.g. stroke unit care). Responses to the EQ‐5D‐3L were transformed into a total utility value (−0.516 'worse than death' to 1 'best' health). Quantile regression models, adjusted for confounding factors, were used to determine median differences (MD) in utility scores by sex. Results: Approximately 60% (6852/11 418) of stroke survivors had an EQ‐5D‐3L assessment (median 139 days; 44% female). Compared with men, women were older (median age 77.1 years vs. men 71.2 years) and fewer could walk on admission (37.9% vs. men 46.1%, P < 0.001). Women had lower utility values than men, and the difference was explained by age and stroke severity, but not clinical care [MDadjusted = −0.039, 95% confidence interval: −0.056, −0.021]. Poorer HRQoL was observed in younger men (aged <65 years), particularly those with more comorbidities, and in older women (aged ≥75 years). Conclusions: Stroke severity and comorbidities contribute to the poorer HRQoL in young men and older women. Further studies are needed to understand age–sex interaction to better inform treatments for different subgroups and ensure evidence‐based treatments to reduce the severity of stroke are prioritized.

Abstract

Background: Uncertainty exists over attributable causes for the excess mortality after stroke, and of any differences by sex. Method(s): First-ever strokes (2010-2013) admitted to 35 hospitals enrolled in the Australian Stroke Clinical Registry (AuSCR) were linked to national death registrations. For this analysis, one-year causes of death due to stroke, ischemic heart disease (IHD), other vascular conditions (e.g. hypertension), and cancer were investigated. Age and sex specific death rates by calendar year expected in the general population were derived from Australian Government data. Expected numbers of deaths were estimated for each sex by multiplying the age-specific person-years of observation by death rate. Standardised mortality rates (SMR; observed/expected deaths) were estimated for causes of death. Result(s): Among 9,441 first-ever events, 46% were women (median age 78 years) who were 6 years older than men (p<0.001) and had higher all-cause one-year mortality (25.4% vs 19.1%, p<0.001). Compared to population norms, those surviving to 30-days had >8 fold increased risk of death from stroke/recurrent events within 1 year irrespective of sex (SMR: men 8.3 vs. women 8.8). For first-ever strokes, the excess risk of death from other vascular conditions was greater in women than men (SMR 4.0 vs 2.8; p=0.04). Compared to population norms, the excess mortality after stroke was greater for IHD (SMR: men 3.5, women 3.0) and cancer (SMR: men 2.6, women 2.6). Conclusion(s): Excess mortality after stroke is mostly attributed to stroke and recurrent events, other cardiovascular conditions and cancer. Secondary stroke prevention should target vascular risk factors and co-morbidity.

Abstract

Introduction: Women appear to receive evidence-based care less often than men but the reasons why are uncertain. We examined sex differences in management of stroke and factors might account for these disparities. Method(s): INSTRUCT is an individual participant data pooling study of incident strokes (1987-2013) from 13 population-based cohorts worldwide. In hospitalised people, log-binomial regression was used to estimate the prevalence ratio (PR) for women compared to men for thrombolysis, admission or discharge medications (antihypertensives, antiplatelets, anticoagulants), investigations (e.g. echocardiography) and surgical interventions (e.g. carotid endarterectomy). Study-specific multivariable models incorporating adjustment for socio-demographics, stroke-related factors and pre-stroke health were combined using random-effects meta-analysis. Result(s): Data were available for 16,054 (52.4% women) people admitted to hospital. Women, compared to men, were older (10/13 studies) and suffered more severe strokes (7/13 studies). Women were slightly more likely to be taking an antihypertensive on admission (3 studies, pooled PRcrude 1.08, 95% CI 1.01-1.16) and less likely to receive echocardiography, (3 studies, pooled PRcrude 0.90, 95% CI 0.82-0.98) or carotid investigations (8 studies, pooled PRcrude 0.89 95% CI 0.81-0.97) inhospital. Adjusting for age and stroke severity attenuated these difference making them non-significant: antihypertensives, pooled PRadjusted, 1.00, 95% CI 0.94-1.07; echocardiography, pooled PRadjusted 1.00 95% CI 0.90-1.12 and carotid investigation, pooled PRadjusted 0.95 95% CI 0.91-1.00. Conclusion(s): Women and men with stroke received equal levels of care. Sex differences were associated with age and stroke severity highlighting the importance of improving care in elderly people and managing modifiable factors for stroke severity.

Abstract

Background and Aims: All-cause mortality after stroke is greater in women than men. Our aim was to examine whether there are sex differences in the causes of death (COD) or the potential contributing factors. Method(s): 1-year COD were obtained by linking first-ever strokes (2010- 2013) admitted to 35 hospitals participating in the Australian Stroke Clinical Registry to national death registrations. COD were categorised as stroke, ischemic heart disease (IHD), other cardiovascular disease (CVD, e.g. hypertension), cancer, and other causes. Competing risk models were used to estimate female:male specific hazard ratios (sHRs) of death with adjustment for factors that differed between men and women (sociodemographics, stroke severity assessed by ability to walk on admission). Result(s): Among 9,441 events (46% women), women were 7 years older (median age 78 vs 72, p<0.001) than men, had more severe stroke (32% vs 41% able to walk on admission, p<0.001), received similar acute care therapies, and had greater all-cause mortality (25.4% vs 19.1% p<0.001). Women had greater risk of death due to stroke (sHRunadjusted 1.65, 95% CI 1.42-1.91) and other CVD (sHRunadjusted 1.65, 95% CI 1.29-2.12), but these differences were substantially attenuated after adjusting for age, stroke severity (stroke: sHRadjusted 1.19, 95% CI 1.02-1.40; other CVD: sHRadjusted 1.12, 95% CI 0.85-1.48). In contrast, women less often died from IHD (sHRadjusted 0.58, 95% CI 0.43+/-0.77), or from cancer (sHRadjusted 0.67, 95% CI 0.49+/-0.91). Conclusion(s): COD after first stroke differ between genders with women having more deaths attributed to stroke or other CVD, reinforcing the need to manage cardiovascular risk factors.

Introduction: Women may receive evidence-based care less often than men after stroke. It is uncertain whether this contributes to sex differences in outcomes. Method(s): We included first-ever strokes admitted to 39 hospitals in the AuSCR during 2010-2014. Mortality 1-year after stroke was obtained from the National Death Index. HRQoL was measured by EQ5D-3L at 3-6 months follow-up. For women compared to men, we estimated the mortality rate ratio (MRR) using multilevel Poisson modelling (accounting for hospital) and the median differences (MD) in HRQoL using quantile regression. Study factors included sociodemographics, stroke type, severity (walking ability on admission) and evidence-based therapies (stroke unit care, thrombolysis, secondary prevention medications, dysphagia screening and mobilisation). Result(s): Data were available for 14,118 strokes (46% women, 81% ischaemic, median age: 75). Women were 7 years older and less able to walk on admission (29% vs 37%, p<0.001) than men. The only difference in evidence-based therapy was that women were less often administered aspirin<=48 hours (51% vs 58%, p=0.014) in a Queensland subset (n=5,224). Mortality was greater in women (MRRcrude 1.45 [95% CI 1.33, 1.59]). Women's lower aspirin administration, advanced age and stroke severity explained the difference (MRRadjusted 1.07 [0.97, 1.17]. About 60% (n=6852) had HRQoL assessments. Only older women compared to older men had poorer EQ5D utility (MD - 0.103 [-0.160, -0.047]) independent of severity. The evidence-based care measures did not contribute to the difference. Conclusion(s): Worse outcomes in women were associated with age, severity and aspirin administration suggesting targets to reduce sex differences in outcomes.

Abstract

Host genetic resistance is the most effective and sustainable means of managing tan spot or yellow spot of wheat. The disease is becoming increasingly problematic due to the adoption of minimum tillage practices, evolution of effector-mediated pathogenicity, and widespread cultivation of susceptible cultivars from a narrow genetic base. This highlights the importance of broadening the diversity of resistance factors in modern breeding germplasm. We explored 300 genetically diverse wheat accessions, originally sourced from the N. I. Vavilov Institute of Plant Genetic Resources (VIR), St. Petersburg, Russia. The collection was screened for resistance to tan spot at seedling and adult stage under controlled conditions, and in the field across two years. The phenotypic datasets, coupled with ToxA bioassay screening, identified a number of accessions with useful sources of resistance. Seedling disease response corresponded well with ToxA sensitivity (r = 0.49, P < 0.000), but not adult responses (r = -0.02–0.19, P < 0.002), and overall reactions to ToxA appeared to show poor correspondence with disease response at the adult stage. ToxA-insensitive accessions were generally found resistant across different growth stages (all-stage resistant, ASR) in all experiments (seedling and adult stage under controlled conditions and field). ToxA-sensitive accessions and susceptible at seedling stage, but resistant at both adult-plant stages, were deemed to carry adult-plant resistance (APR). We provide detailed information on the degree of tan spot resistance in the Vavilov wheat collection and discuss strategies to harness these sources to boost the diversity of resistance factors in modern wheat breeding germplasm.

Abstract

The fungus Parastagonospora nodorum is the causal agent of Septoria nodorum blotch (SNB) of wheat. The pathosystem is mediated by multiple fungal necrotrophic effector–host sensitivity gene interactions that include SnToxA–Tsn1, SnTox1–Snn1, and SnTox3–Snn3. A P. nodorum strain lacking SnToxA, SnTox1, and SnTox3 (toxa13) retained wild-type-like ability to infect some modern wheat cultivars, suggesting evidence of other effector-mediated susceptibility gene interactions or the lack of host resistance genes. To identify genomic regions harbouring such loci, we examined a panel of 295 historic wheat accessions from the N. I. Vavilov Institute of Plant Genetic Resources in Russia, which is comprised of genetically diverse landraces and breeding lines registered from 1920 to 1990. The wheat panel was subjected to effector bioassays, infection with P. nodorum wild type (SN15) and toxa13. In general, SN15 was more virulent than toxa13. Insensitivity to all three effectors contributed significantly to resistance against SN15, but not toxa13. Genome-wide association studies using phenotypes from SN15 infection detected quantitative trait loci (QTL) on chromosomes 1BS (Snn1), 2DS, 5AS, 5BS (Snn3), 3AL, 4AL, 4BS, and 7AS. For toxa13 infection, a QTL was detected on 5AS (similar to SN15), plus two additional QTL on 2DL and 7DL. Analysis of resistance phenotypes indicated that plant breeders may have inadvertently selected for effector insensitivity from 1940 onwards. We identify accessions that can be used to develop bi-parental mapping populations to characterise resistance-associated alleles for subsequent introgression into modern bread wheat to minimise the impact of SNB.

Abstract

In this work, heterostructured catalyst Al2TiO5/TiO2 (ATO/Ti) was synthesized by a two-step method: low-temperature sol-gel process along with hydrothermal treatment in a neutral medium. Characteristics of the fabricated catalyst were analyzed by various techniques including X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller adsorption, UV-Vis diffuse reflectance spectroscopy, energy-dispersive X-ray spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and the point of zero charges. The content of ATO strongly affected the activity of ATO/Ti catalysts for photocatalytic degradation of cinnamic acid (CA). The catalyst, in which 33% TiO2 was replaced by ATO (33ATO/Ti), exhibited the highest activity for the removal of CA. Compared with the bare titanium oxide synthesized in water (TiO2(w)) as well as Al2TiO5 (ATO), the hybrid 33ATO/Ti catalyst exhibited the enhanced photocatalytic activity in the CA degradation under ultraviolet light. The enhancement in the catalytic activity of ATO/Ti could be related to the increase of the specific surface area and the reduction of bandgap energy obtained from the hybridization of TiO2(w) and ATO. The factors as the catalyst dosage ( C cat ), the airflow rate ( Q air ), and the solution initial pH (pH) affected the CA removal efficiency were studied on 33ATO/Ti catalyst. The optimum condition for photodegradation efficiency of CA was found to be at C cat = 0.75 g L − 1 , Q air = 0.3 Lmi n − 1 , and pH = 3.8. The highest 60-minute removal efficiency of CA reached 77.1% on 33ATO/Ti compared with 67.1% and 30.4% on TiO2(w) and on ATO, respectively. The recyclability of the 33ATO/Ti was also measured at the optimal parameters. The results showed that, compared with TiO2, the hybrid catalyst was easier to recover and reuse, and its activity decreased by 35% after 6 continuous cycles. [ABSTRACT FROM AUTHOR]

Abstract

Record linkage, a part of data cleaning, is recognized as one of most expensive steps in data warehousing. Most record linkage (RL) systems employ a strategy of using blocking filters to reduce the number of pairs to be matched. A blocking filter consists of a number of blocking criteria. Until recently, blocking criteria are selected manually by domain experts. This paper proposes a new method to automatically learn efficient blocking criteria for record linkage. Our method addresses the lack of sufficient labeled data for training. Unlike previous works, we do not consider a blocking filter in isolation but in the context of an accompanying matcher which is employed after the blocking filter. We show that given such a matcher, the labels (assigned to record pairs) that are relevant for learning are the labels assigned by the matcher (link/nonlink), not the labels assigned objectively (match/unmatch). This conclusion allows us to generate an unlimited amount of labeled data for training. We formulate the problem of learning a blocking filter as a Disjunctive Normal Form (DNF) learning problem and use the Probably Approximately Correct (PAC) learning theory to guide the development of algorithm to search for blocking filters. We test the algorithm on a real patient master file of 2.18 million records. The experimental results show that compared with filters obtained by educated guess, the optimal learned filters have comparable recall but reduce throughput (runtime) by an order-of-magnitude factor.
