description: Secondary enzyme-substrate contacts in the hydrolysis of ester substrates by the cysteine protease papain were investigated by systematically altering backbone hydrogen bonding and side chain hydrophobic contacts in the substrate and determining each substrate's $k\sb{\rm cat}/K\sb{\rm M}$. $k\sb{\rm cat}/K\sb{\rm M}$, the second order rate constant, directly reflects the equilibrium of free enzyme plus free substrate to the enzyme-substrate transition state. The incremental binding energies of the substrate backbone hydrogen bonds are estimated at $-$2.3 kcal/mol for the P$\sb2$ NH, $-$2.2 kcal/mol for the P$\sb1$ NH, and $-$2.3 kcal/mol for the P$\sb{2\sp\prime}$ NH. The observed hydrogen bonding energy for the substrate backbone P$\sb{1\sp\prime}$ C=O is $-$1.0 kcal/mol. The incremental binding energy of the Phe side chain in the P$\sb2$ position is estimated at $-$4.0 kcal/mol. The contacts on the acyl side of the scissile bond (the P$\sb2$ NH, P$\sb2$ Phe side chain and P$\sb1$ NH) display a strong interdependence of binding energies that is characteristic of enzyme-substrate interactions. This interdependence arises largely from the entropic cost of forming the rate-determining enzyme-substrate transition state. As favourable contacts are added successively to a substrate, the entropic penalty associated with each decreases and the binding energy expressed approaches the incremental binding energy. On the leaving group side, the observed $-$1.0 kcal/mol for the P$\sb{1\sp\prime}$ C=O probably underestimates the incremental binding energy whilst the $-$2.3 kcal/mol for the P$\sb{2\sp\prime}$ NH is a reasonable estimate. Elucidation of favourable enzyme-substrate contacts remote from the catalytic site will assist in the design of highly specific cysteine protease inhibitors.

description: Optical burst switching (OBS) is the most promising all-optical architectures for the next generation Internet. OBS is still being developed and several issues still need to be addressed. Several studies have stressed the importance of the choice of the offset time and its criticality in influencing the burst loss phenomenon in OBS networks. The main problem arises in estimating the initial delay that is compatible with the optical burst switching architecture implemented. This thesis aims to provide a mechanism to calculate the offset time and to study its effect on the network performance and refining QoS levels. The study is extended to networks under failure to investigate the influence of the delay factor on the restoration process especially in compensating failed-network performance degradations. The simulation studies validated the proposed mechanism and formed an annex that can be integrated on any OBS restoration mechanism. A new QoS parameter is defined to meet service differentiation with respect to the data losses and delays.

description: Background: The mitogen-activated protein kinase (MAPK) family is involved in signal transduction networks that underpin many different biological processes in plants, ranging from development to biotic and abiotic stress responses. To date this class of enzymes has received little attention in Triticeae species, which include important cereal crops (wheat, barley, rye and triticale) that represent over 20% of the total protein food-source worldwide. Results: The work presented here focuses on two subfamilies of Triticeae MAPKs, the MAP kinases (MPKs), and the MAPK kinases (MKKs) whose members phosphorylate the MPKs. In silico analysis of multiple Triticeae sequence databases led to the identification of 152 MAPKs belonging to these two sub-families. Some previously identified MAPKs were renamed to reflect the literature consensus on MAPK nomenclature. Two novel MPKs, MPK24 and MPK25, have been identified, including the first example of a plant MPK carrying the TGY activation loop sequence common to mammalian p38 MPKs. An EF-hand calcium-binding domain was found in members of the Triticeae MPK17 clade, a feature that appears to be specific to Triticeae species. New insights into the novel MEY activation loop identified in MPK11s are offered. When the exon-intron patterns for some MPKs and MKKs of wheat, barley and ancestors of wheat were assembled based on transcript data in GenBank, they showed deviations from the same sequence predicted in Ensembl. The functional relevance of MAPKs as derived from patterns of gene expression, MPK activation and MKK-MPK interaction is discussed. Conclusions: A comprehensive resource of accurately annotated and curated Triticeae MPK and MKK sequences has been created for wheat, barley, rye, triticale, and two ancestral wheat species, goat grass and red wild einkorn. The work we present here offers a central information resource that will resolve existing confusion in the literature and sustain expansion of MAPK research in the crucial Triticeae grains.

description: Drug therapy for diabetes mellitus has increased significantly in recent years. 1,1-Dimethylbiguanide hydrochloride (metformin) is the most common drug used for the treatment of diabetes. Metformin is not metabolized in the human body and enters the water cycle via sewage. A new gas chromatography-mass spectrometry (GC-MS) method has been developed which enables the quantification of metformin in surface water samples even at low concentrations in the ng L-1 range. A solid phase extraction (SPE) method for the preconcentration of metformin and the internal standard 1-butylbiguanide (buformin) was established, and the method parameters such as the composition and volume of the eluent were optimized. Derivatization of metformin and buformin was obtained by using n-methyl-bis (trifluoroacetamide) (MBTFA). The reaction conditions of the derivatization, such as the reaction temperature and volume of the derivatization agent, were evaluated. The limit of detection (LOD) and limit of quantification (LOQ) were determined to be 3.9 ng L-1 and 12 ng L-1 in surface water samples. Linearity was shown over a concentration range of 10-50 ng L-1. The good performance of the method was demonstrated by comparison with a liquid chromatography tandem mass spectrometry (LC-MS/MS) method. The results indicate that the GC-MS method is a reliable and sensitive alternative for the quantification of metformin in surface water. Quelle: http://pubs.rsc.org
Design, construction, validation, and integration of the dynamic collimation system for pencil beam scanning proton therapy
Creators: name: Geoghegan, Theodore

Year: 2023
Subjects: public abstract

description: Purpose: This work summarizes the development of a prototype energy-layer specific collimator, called the dynamic collimation system (DCS), to reduce the lateral penumbra of pencil beam scanning proton therapy treatments.
description: Methods: From a basic concept, we developed a prototype using an in-house Monte Carlo beam model to drive design decisions that would minimize lateral penumbra, such as range shifter characteristics and the use of dynamically focused collimators. Because the DCS is a removable accessory, we developed a quality control alignment system called the Central Axis Alignment Device (CAAD) to ensure alignment. Using TOPAS generated simple fields, EBT3 film and a MatriXX-PT IC array, treatment accuracy was quantified for a set of clinically representative deliveries where the automated positioning of the collimators was synchronized with the scanned position of the proton beam.
description: Results: We successfully designed and constructed the DCS to meet the required scientifically driven design decisions. Our control system was integrated with the IBA scanning controller to allow automated treatments with a low latency (<45 ms). Positional trimmer accuracy was verified to within 50 µm and the kinematics were tuned to be stable under gantry conditions up to an operating jerk value of 400 m/s^3. The CAAD aligns the collimators with respect to the field with an accuracy of less than 100 um. Mean dose reductions of 12% and 45% to the 10- and 30-mm rings surrounding a target were achieved in preliminary automated treatment deliveries.
description: Conclusion: This work signifies a significant milestone in the development of the DCS clinical prototype. The mechanical systems were successfully characterized and integrated within a commercial IBA scanning controller, enabling preliminary dosimetric studies for clinical treatments.

description: Microplastic (MP) contamination in natural water circulation is a concern for environmental issues and human health. Various types of polymer materials have been identified and were detected in MP analytic test procedures. Beyond MP polymer type, particle size and form play a major role in water analysis due to possible negative toxicologic effects on flora and fauna. However, the correct quantitative measurement of MP size distribution over several orders of magnitude is strongly influenced by sample preparation, filtration materials and processes, and microanalytical techniques, as well as data acquisition and analysis. In this paper, a reference methodology is presented aiming at an improved quantitative analysis of MP particles. An MP analysis workflow is demonstrated including all steps from reference materials to sample preparation, filtration handling, and MP particle size distribution analysis. Background-corrected particle size distributions (1â€Ì1000â€ Ìm) have been determined for defined polyethylene (PE) and polyethylene terephthalate (PET) reference samples. Microscopically measured particle numbers and errors have been cross-checked with the total initial mass. In particular, defined reference MP samples (PE, PET) are initially characterized and applied to filtration experiments. Optical microscopy imaging on full-area Si filters with subsequent image analysis algorithms is used for statistical particle size distribution analysis. To quantify the effects of handling and filtration, several blind tests with distilled water are carried out to determine the particle background for data evaluation. Particle size distributions of PE and PET reference samples are qualitatively and quantitatively reproduced with respect to symmetry, and maximum and cut-off diameter of the distribution. It is shown that especially MP particles with a radius of >50â€ Ìm can be detected and retrieved with high reliability. For particle sizes <50â€ Ìm, a significant interference with background contamination is observed. Data from blank samples allows a correction of background contaminations. Furthermore, for enhanced sampling statistics, the recovery of the initial amount of MP will be qualitatively shown. The results are intended as an initial benchmark for MP analytics quality. This quality is based on statistical MP particle distributions and covers the complete analytic workflow starting from sample preparation to filtration and detection. Microscopic particle analysis provides an important supplement for the evaluation of established spectroscopic methods such as Fourier-transform infrared spectroscopy or Raman spectroscopy. © 2022 The Authors

description: Background Whilst being the most prevalent disease worldwide, dental caries is increasingly concentrated in high-risk populations. New caries treatments should therefore be evaluated not only in terms of their cost-effectiveness in individuals, but also their effects on the distribution of costs and benefits across different populations. To treat deep caries, there are currently three strategies: selective (one-step incomplete), stepwise (two-step incomplete) and complete excavation. Building on prior research that found selective excavation generally cost-effective, we compared the costs-effectiveness of different excavations in low- and high-risk patients, hypothesizing that selective excavation had greater cost-effectiveness-advantages in patients with high compared with low risk. Methods An average tooth-level Markov-model was constructed following the posterior teeth in an initially 18-year old male individual, either with low or high risk, over his lifetime. Risk was assumed to be predicted by several parameters (oral hygiene, social position, dental service utilization), with evidence-based transition probabilities or hazard functions being adjusted for different risk status where applicable. Total lifetime treatment costs were estimated for German healthcare, with both mixed public-private and only private out-of-pocket costs being calculated. For cost-effectiveness-analysis, micro-simulations were performed and joint parameter uncertainty introduced by random sampling of probabilities. Cohort analyses were used for assessing the underlying reasons for potential differences between strategies and populations. Results Selective excavation was more effective and less costly than both alternatives regardless of an individual’s risk. All three strategies were less effective and more costly in patients with high compared with low risk, whilst the differences between risk groups were smallest for selective excavation. Thus, the cost-effectiveness- advantages of selective excavation were more pronounced in high-risk groups, who also benefitted the most from reduced private out-of-pocket treatment costs. Conclusions Whilst caries excavation does not tackle the underlying sources for both the development of caries lesions and the potential differences of individuals’ risk status, selective excavation seems most suitable to treat deep lesions, especially in patients with high risk, who over-proportionally benefit from the resulting health-gains and cost-savings.

description: Classification of electromyography (EMG) signals, also known as muscle signals, allow the study of human movements via the extraction of useful patterns from the signals after proper processing. An optimized approach is developed and introduced to enhance the performance of the classification system to improve the accuracy on classification of wrist and finger movements. A graphical user interface that allows user to upload and classify EMG signals is created. With further modifications, the output from the graphical user interface can be used to control an exoskeleton unit to mimic human movements, or to monitor human movements for ergonomic studies.
Facing down the lion: Canada's refusal to support the Egyptian expedition, 1882

description: This thesis outlines the influences that shaped Canada's refusal to support Britain's occupation of Egypt in 1882. Here, Canada set a precedent of inaction that continued as a seminal part of its approach to foreign policy. The excuse of legal constraints in the Militia Act was given as the official reason for the refusal in 1882; of greater importance, however, were the series of underlying factors that brought Canada to this decision. Indeed, in many ways, this was a decision more than a decade in the making. As an often overlooked event in Canadian history, this thesis has relied on a variety of primary sources to assess the influences that affected the key decision-makers, provide an indication of the popular opinion, and, in a larger sense, point to the fact that this episode is of more significance than the attention it has garnered to date in Canadian historiography.

description: This thesis discusses the issues of Automatic Speech Recognition in presence of additive white noise. Comb Filter Decomposition (CFD), a new method for approximating the magnitude of the speech spectrum in terms of its harmonics is proposed. Three feature extraction methods from CFD coefficients are introduced. The performance of the method and resulting features are evaluated using simulated recognition systems with Hidden Markov Model classifiers and conditions of additive white noise under varying Signal to Noise ratios. The results are compared with the performance of the existing robust feature extraction methods. The results show that the proposed method has a good potential for Automatic Speech Recognition under noisy conditions.
An investigation in acquiring Chinese relative clauses by advanced Chinese L2 learners
Creators: name: Dai, Dexin
Publisher: name: University of Iowa
Year: 2023
Subjects: public abstract

description: The present study was focused on the acquisition of Chinese relative clauses (RCs) by second language (L2) learners and whether this acquisition was influenced by RC linguistic features, learners’ Chinese proficiency levels, and their first language (L1). Data were gathered via a Chinese reading comprehension test, a grammaticality judgment task, a sentence combination task, a sentence formation task, and post-task interviews.
description: An analysis of 46 Chinese learners’ and 22 native speakers’ performances on these tasks and 15 learners’ perspectives from the interviews revealed that the acquisition of RCs was challenging for learners, particularly with the use of the RC marker de. Furthermore, the types of RC and Chinese proficiency levels significantly impacted the learners’ acquisition of RCs. The results indicated that learners could comprehend both subject RCs (SRCs) and object RCs (ORCs) with comparable accuracy, but they produced more correct sentences with ORCs than with SRCs. Additionally, learners’ L1 influenced their acquisition of Chinese RCs, which was evident from the errors made with de as an RC marker and the production of Chinese RCs with English word order. The interview data confirmed that learners’ perceptions of Chinese RCs played a role in the L1 transfer effect on their acquisition.
description: The results of the current study have implications for teaching Chinese RCs and suggest the need for frequent input on RCs in classroom instruction. Task-based language teaching activities and multimodal input can provide more meaningful and engaging input to learners and improve their accuracy and fluency in using RCs. Explicit instruction to explain the syntactic features of RCs to learners is also recommended. RC instruction should start with SRC and then proceed to ORC. Teachers are encouraged to communicate with students about their perceptions of the differences and similarities between RCs in their L1 and the target language to further analyze their errors and learning strategies.

description: Introduction Phthalates, a group of ubiquitous industrial chemicals, have been widely used in occupational settings, mainly as plasticizers in a variety of applications. Occupational exposure to different phthalates has been studied in several occupational settings using human biomonitoring (HBM). Aim To provide a comprehensive review of the available literature on occupational exposure to phthalates assessed using HBM and to determine future data needs on the topic as part of the HBM4EU project. Methods A systematic search was carried out in the databases of Pubmed, Scopus, and Web of Science for articles published between 2000 and September 4, 2019 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 22 studies on the occupational HBM of phthalates was considered suitable for review. Results and discussion Among the reviewed studies, 19 (86%) focused on DEHP, an old phthalate that is now subject to authorization and planned to be restricted in the EU. Concentrations of MEHHP, one of its metabolites, varied up to 13-fold between studies and across sectors when comparing extreme geometric means, ranging from 11.6 (similar to the general populations) to 151 ÎÌg/g creatinine. Only 2 studies focused on newer phthalates such as DiNP and DPHP. Concerning the geographical distribution, 10 studies were performed in Europe (including 6 in Slovakia), 8 in Asia, and 4 in North America, but this distribution is not a good reflection of phthalate production and usage levels worldwide. Most HBM studies were performed in the context of PVC product manufacturing. Future studies should focus on: i) a more uniform approach to sampling timing to facilitate comparisons between studies; ii) newer phthalates; and iii) old phthalates in waste management or recycling. Conclusion Our findings highlight the lack of recent occupational HBM studies on both old and new phthalate exposure in European countries and the need for a harmonized approach. Considering the important policy actions taken in Europe regarding phthalates, it seems relevant to evaluate the impact of these actions on exposure levels and health risks for workers. © 2020 The Authors

description: The bile fluid contains various lipids that are secreted at the canalicular membrane of hepatocytes. As the secretion mechanism is still a matter of debate and a direct experimental observation of the secretion process is not possible so far, we used a mathematical model to simulate the extraction of the major bile lipids cholesterol, phosphatidylcholine and sphingomyelin from the outer leaflet of the canalicular membrane. Lipid diffusion was modeled as random movement on a triangular lattice governed by next-neighbor interaction energies. Phase separation in liquid-ordered and liquid-disordered domains was modeled by assigning two alternative ordering states to each lipid species and minimization of next-neighbor ordering energies. Parameterization of the model was performed such that experimentally determined diffusion rates and phases in ternary lipid mixtures of model membranes were correctly recapitulated. The model describes the spontaneous formation of nanodomains in the external leaflet of the canalicular membrane in a time window between 0.1 ms to 10 ms at varying lipid proportions. The extraction of lipid patches from the bile salt soluble nanodomain into the bile reproduced observed biliary phospholipid compositions for a physiologi-cal membrane composition. Comparing the outcome of model simulations with available experi-mental observations clearly favors the extraction of tiny membrane patches composed of about 100–400 lipids as the likely mechanism of biliary lipid secretion.

description: Cette these vise a demontrer la nature sexuee de la mondialisation de l'economie en expliquant comment le fonctionnement de la mondialisation de l'economie repose sur des idees quant aux rapports sociaux de sexe qui renforcent la marginalisation et l'exploitation des femmes. Plus precisement, a l'aide d'une approche feministe neo-gramscienne, cette these revele que cette marginalisation et cette exploitation des femmes sont perpetuees par la facon dont les changements associes a la mondialisation de l'economie profitent d'idees devalorisant le travail des femmes, mais aussi par les interventions decoulant du feminisme liberal, telles celles mises de l'avant par l'ONU dans le cadre de la Conference de Beijing qui eut lieu en septembre 1995. L'essentiel de cette these consiste donc a confronter les causes profondes de la marginalisation et de l'exploitation des femmes associees au contexte de la mondialisation de l'economie et la capacite du feminisme liberal, tel qu'en fait usage I'ONU, de remedier a de tels problemes. Cette these conclut que les recommandations onusiennes emanant de la Conference de Beijing se veulent une illustration de l'incapacite de l'approche feministe liberale d'elaborer des solutions qui permettent vraiment d'admettre la nature profondement sexuee de la mondialisation de l'economie et de resoudre les problemes de marginalisation et d'exploitation des femmes qui en decoulent.

description: Objective Ayurveda is commonly used in South Asia to treat knee osteoarthritis (OA). We aimed to evaluate the effectiveness of Ayurvedic treatment compared to conventional conservative care in patients with knee OA. Method According to American College of Rheumatology (ACR) criteria knee OA patients were included in a multicenter randomized, controlled, open-label trial and treated in 2 hospital clinics and 2 private outpatient clinics in Germany. Participants received either a multi-modal Ayurvedic treatment or multi-modal conventional care with 15 treatments over 12 weeks respectively. Primary outcome was the change on the Western Ontario and McMaster University Osteoarthritis (WOMAC) Index after 12 weeks. Secondary outcomes included WOMAC subscales; the pain disability index and a pain experience scale, numeric rating scales for pain and sleep quality, quality-of-life and mood, rescue medication use, and safety issues. Results One hundred fifty-one participants (Ayurveda n = 77, conventional care n = 74) were included. Changes of the WOMAC Index from baseline to 12 weeks were more pronounced in the Ayurveda group (mean difference 61.0 [95%CI: 52.4;69.6]) than in the conventional group (32.0 [95%CI: 21.4;42.6]) resulting in a significant between-group difference (p < 0.001) and a clinically relevant effect size (Cohen's d 0.68 [95% CI:0.35;1.01]). Similar trends were observed for all secondary outcomes at week 12. Effects were sustained at follow-ups after 6 and 12 months. Conclusion Results suggest that Ayurvedic treatment is beneficial in reducing knee OA symptoms. Further studies should be conducted to confirm the magnitude of the effect and to clarify the role of different treatment components and non-specific effects.

public abstract

description: Individuals with a growth mindset believe that their abilities can be improved through effort, which enables them to perceive challenges as manageable obstacles and attain higher achievement. Sociological factors (such as poverty and the social implications of minoritized identities) create self-efficacy limitations that hinder the attainment of a growth mindset. Although studies have shown the impact that identity can have on the development of a growth mindset and that interventions can increase growth mindset, this study investigated how identity (race/ethnicity) and its salience relates to a growth mindset intervention when there is an ethnoracial match versus when racial/ethnic identity is not identified. Participants (N = 607) were recruited through Qualtrics’ survey recruitment service and anonymously completed an online survey. Results suggested there was a significant increase in growth mindset in both the race/ethnicity match and control condition. Additionally, White participants reported significantly lower ethnic identity salience than did Black, Biracial, and Latinx participants. Identity salience explained 51% of the variance in posttest growth mindset in both the control and race/ethnicity match conditions. The interaction between ethnic identity salience explained an additional .3% of the variance in growth mindset change. Specifically, among individuals with higher ethnic identity salience, the impact on growth mindset was higher in the ethnomatching condition than in the control condition, but the opposite was true among those with lower ethnic identity salience. The higher an individual’s ethnic identity salience, the greater their likelihood of benefiting from an intervention that primes their ethnoracial identity. These findings are important to the growth mindset intervention literature in that the impact of ethnic identity salience is nuanced among individuals and may impact outcomes differently. For some, race/ethnicity matching may be a more important factor to changing growth mindset than for others.

description: This article proposes a generic framework to process jointly the spatial and spectral information of hyperspectral images. First, sub-images are extracted. Then each of these sub-images follows two parallel workflows, one dedicated to the extraction of spatial features and the other dedicated to the extraction of spectral features. Finally, the extracted features are merged, producing as many scores as sub-images. Two applications are proposed, illustrating different spatial and spectral processing methods. The first one is related to the characterization of a teak wood disk, in an unsupervised way. It implements tensors of structure for the spatial branch, simple averaging for the spectral branch and multi-block principal component analysis for the fusion process. The second application is related to the early detection of apple scab on leaves. It implements co-occurrence matrices for the spatial branch, singular value decomposition for the spectral branch and multiblock partial least squares discriminant analysis for the fusion process. Both applications demonstrate the interest of the proposed method for the extraction of relevant spatial and spectral information and show how promising this new approach is for hyperspectral imaging processing.

Strains of E. sakazakii were isolated from dried-infant formula available on the Canadian retail market. The prevalence varied from 0--12% in 120 samples evaluated from 5 different companies. Nine clinical E. sakazakii strains were obtained from Canadian hospital culture collections. Minimum growth temperatures of 7.0 to 8.5°C were observed. Average generation times were 40 min at 23°C and 4.98 h at 10°C. E. sakazakii strains did not grow at 4°C and appeared to die-off during storage. Heat resistance studies determined the heat resistance of this organism at 52, 54, 56, 58 and 60°C, obtaining D-values of 54.8, 23.7, 10.3, 4.2 and 2.5 min, respectively. The overall calculated z-value was 5.82°C. Using the standard suckling mouse assay, it was found that four strains (1 food and 3 clinical) produced enterotoxin. Dose response studies indicated that 15 of 18 E. sakazakii strains caused lethality in mice by intraperitoneal injection, two through oral feeding. From the 18 strains examined, 3 biotypes and 4 antibiogram patterns were observed. Ribotyping categorized the test strains into 10 clusters. Two decamer primers were selected for random amplification of polymorphic DNA (RAPD) typing. Banding patterns were similar for three strains isolated from the same hospital, although each strain was isolated in a different year. All three of the food isolates from company A showed similar profiles, while two food strains isolated from Company B formula revealed different profiles. Pulsed-field gel electrophoresis (PFGE) revealed a similar number of bands to that of RAPD (4--13 bands), giving distinguishable patterns that allowed for the comparison of E. sakazakii strains. RAPD and PFGE were the most discriminatory methods for distinguishing clinical and food isolates of E. sakazakii. Overall, the abilities of RAPD and PFGE to differentiate between strains were comparable, followed by ribotyping, biotyping and antibiograms. In conclusion, my studies have found that E. sakazakii is prevalent in dried-infant formula available on the Canadian retail market. This organism can grow at temperatures found in many home refrigerators. Growth studies in reconstituted dried-infant formula indicate a generation time of only 40 min at ambient temperatures. Heat resistance studies indicate that E. sakazakii appears to be one of the most thermotolerant organisms among the Enterobacteriaceae. (Abstract shortened by UMI.)

description: Monitoring of water quality is important to control water pollution. Contamination of the aquatic system has a large effect on human health and the environment. Under the European Water Framework Directive (WFD) 2000/60/EC and the related directive on environmental quality standards (EQS) in the field of water policy 2008/105/EC, the need for sensitive reference methods was highlighted. Since tributyltin (TBT) is one of the WFD listed priority substances a method was developed which is capable to qualify and quantify the pollutant at the required low WFD EQS of 0.2 ng L-1 in whole water bodies, i.e. in non-filtered water samples with dissolved organic carbon and suspended particulate matter. Therefore special attention was paid on the interaction of TBT with the suspended particulate matter and humic substances to obtain a complete representation of the pollution in surface waters. Different water samples were investigated varying the content of organic dissolved and suspended matter. Quantification was performed using species-specific isotope dilution (SSID) and gas chromatography with inductively coupled plasma mass spectrometry (GC-ICP-MS). Different sample treatment strategies were evaluated and compared. The process of internal standard addition was investigated and optimized, hence the equilibrium between internal standards and matrix is of primary importance to perform accurate SSID. Samples spiked at EQS level were analyzed with a recovery between 95 and 105 %. Additionally real surface water samples were investigated and the TBT concentration for the whole water body was determined and compared with conventional routine analysis method.Quelle: http://www.sciencedirect.com

description: Background/Aims: Ocular surface health depends on conjunctival epithelial (HCjE) layer integrity since it protects against pathogenic infiltration and contributes to tissue hydration maintenance. As the same increases in tear film hyperosmolarity described in dry eye disease can increase corneal epithelial transient receptor potential vanilloid type-1 (TRPV1) channel activity, we evaluated its involvement in mediating an osmoprotective effect by L-carnitine against such stress. Methods: Using siRNA gene silencing, Ca2+imaging, planar patch- clamping and relative cell volume measurements, we determined if the protective effects of this osmolyte stem from its interaction with TRPV1. Results: TRPV1 activation by capsaicin (CAP) and an increase in osmolarity to≈450 mOsM both induced increases in Ca2+levels. In contrast, blocking TRPV1 activation with capsazepine (CPZ) fully reversed this response. Similarly, L-carnitine (1 mM) also reduced underlying whole-cell currents. In calcein-AM loaded cells, hypertonic-induced relative cell volume shrinkage was fully blocked during exposure to L-carnitine. On the other hand, in TRPV1 gene-silenced cells, this protective effect by L-carnitine was obviated. Conclusion: The described L-carnitine osmoprotective effect is elicited through suppression of hypertonic-induced TRPV1 activation leading to increases in L-carnitine uptake through a described Na+-dependent L-carnitine transporter.

description: The adsorption of water on the (110) surface of rutile is investigated by recording Thermal Desorption spectra, and characterizing the substrate using Low Energy Electron Diffraction. The sample is sputtered and annealed according to a previous flattening study of the same surface. After cooling to T $\approx$ 110K, the surface is dosed with H$\sb2$O. The adsorbate/substrate system is heated at 1K/s, and the H$\sb2$O partial pressure is measured with a shrouded quadrupole mass spectrometer. Three desorption peaks are observed below room temperature, two monolayer peaks: one at 310-260K (coverage dependence) and another at 175K, and one multilayer peak at 150K. A fourth peak, representing a coverage of the order of a few percent of a monolayer, is observed at T $\approx$ 500K; this peak is associated with an adsorption state that is more strongly bound than the other three. Analysis of the first three adsorption states provides information on the kinetics of the system, and the bond energies at these adsorption sites.

description: Current text-video retrieval methods mainly rely on cross-modal matching between queries and videos to calculate their similarity scores, which are then sorted to obtain retrieval results. This method considers the matching between each candidate video and the query, but it incurs a significant time cost and will increase notably with the increase of candidates. Generative models are common in natural language processing and computer vision, and have been successfully applied in document retrieval, but their application in multimodal retrieval remains unexplored. To enhance retrieval efficiency, in this paper, we introduce a model-based video indexer named T2VIndexer, which is a sequence-to-sequence generative model directly generating video identifiers and retrieving candidate videos with constant time complexity. T2VIndexer aims to reduce retrieval time while maintaining high accuracy. To achieve this goal, we propose video identifier encoding and query-identifier augmentation approaches to represent videos as short sequences while preserving their semantic information. Our method consistently enhances the retrieval efficiency of current state-of-the-art models on four standard datasets. It enables baselines with only 30\%-50\% of the original retrieval time to achieve better retrieval performance on MSR-VTT (+1.0%), MSVD (+1.8%), ActivityNet (+1.5%), and DiDeMo (+0.2%).

description: I have demonstrated complex light generation using Diffractive Optical Elements and also using the recently emerging Metasurfaces. We have improved the generation efficiency by adopting the all-dielectric multi-phase level metasurfaces that offer very high spatial phase resolution. We have experimentally demonstrated the complex light generation across visible, infrared and terahertz spectral regions. I have also developed two software called GDoeSII and MetaOptics to create GDSII layouts of DOEs and metasurfaces respectively. Both this software are published in reputed journals and received critical appreciation from the community.
