Particle Image Velocimetry Analysis for the Assessment of Bedload Sampling Using Helley-Smith

Field: Environmental Science (Physical Sciences)

Excess sediment is one of the main agents of water pollution, affects the aquatic ecosystem and causes siltation problems in reservoirs and rivers. Bottom sediments are coarse and easily deposited, being the major responsible for morphological alterations in rivers. Therefore, is important to estimate the amount of sediment transported in other to establish mitigation strategies and recovery of affected areas. There are several methodologies for estimating bedload transport: equations, numerical modeling, direct physical sampling, and indirect method measuring dune tracking. Most studies measure bedload transport using the equipment Helley-Smith, generally taken as reference value for other methods. However, Helley-Smith causes changes in the flow field, often resulting in overestimates in sand bed rivers. Those overestimates were not yet described and quantified in detail. This article tries to solve this gap by observing the Helley-Smith sampler at the time of sampling. For this, we used a video camera recording processed by Particle Image Velocimetry (PIV) technique to qualitatively evaluate changes that the intrusive sampler causes in the displacement of bottom sediments in a sand bed river. When the sampler was properly allocated to the bottom, PIV resulting velocity maps of bedload particle transport identified the acceleration of the bottom particles as they approached the mouth of the sampler. We also noticed areas of convergence and vorticity of the sediments towards the sampler’s mouth, which may overestimate sampling. When the sampler’s mouth was disconnected from the bed due to the morphology of the bottom, we find regions of divergence in the displacement of the sediments creating unrealistic results for bedload transport analysis. In addition, the presence of organic matter can be underestimated, which causes difficulties in analyzing the quality of the collections because it is not possible to guarantee an equity in the positioning of the equipment at the bottom of the channel. We thus recommend complementation Helley-Smith measurements with surrogate methods, for example such as using ADCPs or optical methods, as the one described here.
Comparison of self-reported measures of alcohol-related dependence among young Swiss men: a study protocol for a cross-sectional controlled sample

Field: Medicine (Health Sciences)

Introduction Short screenings of alcohol-related dependence are needed for population-based assessments. A clinical interview constitutes a reliable diagnosis often seen as gold standard, but it is costly and time consuming and as such, not suitable for population-based assessments. Therefore, self-reported questionnaires are needed (eg, alcohol use disorder (AUD) as in the Diagnostic and Statistic Manual of Mental Disorders (DSM) 5), but their reliability is questionable. Recent studies called for more evidence-based measurements for population-based screening (eg, heavy alcohol use over time (HAU)). This study aims to test the reliability of different self-reported measures of alcohol use. Methods and analysis Based on stratified random selection, 280 participants will be recruited from the French-speaking subgroup of the Swiss National Science Foundation-supported Cohort Study on Substance Use and Risk Factors (C-SURF). This cohort is a population-based sample of young Swiss men in their mid-20s (n=2668). The sample size calculation is based on a proportion non-inferiority test (alpha=5%, power=80%, margin of equivalence=10%, difference in sensitivity between self-reported AUD and HAU=5%, correlation between AUD and HAU=0.35, and drop-outs=15%). Assessment will include a clinical interview as the gold standard of alcohol-related dependence, self-reported alcohol measures (HAU, AUD and drinking patterns), biomarkers as gold standards of chronic excessive drinking, and health outcomes. To assess the validity of the self-reported alcohol measures, sensitivity analyses will be run. The associations between alcohol-related measures and health outcomes will be tested. A non-response analysis will be run using the previous waves of the C-SURF study using logistic regressions. Ethics and dissemination The study protocol has been approved by the Human Research Ethics Committee of the Canton of Vaud, Switzerland (no. 2017–00776). The results will be submitted for publication in peer-reviewed journals and presented at national and international conferences.
Assessing Helicobacter pylori motility and biofilm formation in subinhibitory concentrations of antimicrobials

Field: Immunology and Microbiology (Life Sciences)

Numerous studies have shown that subinhibitory concentrations of antimicrobials can alter bacterial virulence factors. This study evaluates motility and biofilm formation by H. pylori 43504 grown in subinhibitory concentrations of amoxicillin (AMX), clarithromycin (CLA), or tetracycline (TET). For the swimming and swarming motility assays, H. pylori 43504 suspensions were prepared with the strain alone or with the strain in AMX, CLA, or TET at ½ MIC. Next, the media were incubated at 37 ºC, under microaerophilia. To assess biofilm formation in the presence of one of the antimicrobials at subinhibitory antimicrobial concentrations, bacterial suspensions (109 CFU/mL) were prepared in 2.5% FBS containing AMX, CLA, or TET at ½ MIC. After incubation for 10 days, H. pylori 43504 grown in medium containing AMX, CLA, or TET at ½ MIC presented greater swimming motility and lower swarming motility than the non-treated strain. H. pylori 43504 grown in medium containing AMX, CLA, or TET at ½ MIC showed stronger biofilm production than the non-treated strain. Our results showed that AMX, CLA, or TET at subinhibitory concentrations favors H. pylori 43504 swimming motility and biofilm formation after incubation for 3 days. This may have clinical consequences and make the microorganism difficult to eradicate.
Tachyonic Resonance Preheating in Expanding Universe

Field: Physics and Astronomy (Physical Sciences)

In this paper the tachyonic resonance preheating generated from the bosonic trilinear $ϕχ^2$ interactions in an expanding Universe is studied. In $λϕ^4/4$ inflationary model the trilinear interaction, in contrast to the four-legs $ϕ^2χ^2$, breaks the conformal symmetry explicitly and the resonant source term becomes non-periodic, making the Floquet theorem inapplicable. We find that the occupation number of the produced $χ$-particles has a non-linear exponential growth with exponent $\sim x^{3/2}$, where $x$ is the conformal time. This should be contrasted with preheating from a periodic resonant source, arising for example from the four-legs $ϕ^2χ^2$ interaction, where the occupation number has a linear exponential growth. We present an analytic method to compute the interference term coming from phases accumulated in non-tachyonic scattering regions and show that the effects of the interference term causes ripples on $x^{3/2}$ curve, a result which is confirmed by numerical analysis. Studying the effects of back-reaction of the $χ$-particles, we show that tachyonic resonance preheating in our model can last long enough to transfer most of the energy from the background inflation field $ϕ$, providing an efficient model for preheating in the chaotic inflation models.
MYC function and regulation in flies: how Drosophila has enlightened MYC cancer biology

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Progress in our understanding of the complex signaling events driving human cancer would have been unimaginably slow without discoveries from Drosophila genetic studies. Significantly, many of the signaling pathways now synonymous with cancer biology were first identified as a result of elegant screens for genes fundamental to metazoan development. Indeed the name given to many core cancer-signaling cascades tells of their history as developmental patterning regulators in flies—e.g. Wingless (Wnt), Notch and Hippo. Moreover, astonishing insight has been gained into these complex signaling networks, and many other classic oncogenic signaling networks (e.g. EGFR/RAS/RAF/ERK, InR/PI3K/AKT/TOR), using sophisticated fly genetics. Of course if we are to understand how these signaling pathways drive cancer, we must determine the downstream program(s) of gene expression activated to promote the cell and tissue over growth fundamental to cancer. Here we discuss one commonality between each of these pathways: they are all implicated as upstream activators of the highly conserved MYC oncogene and transcription factor. MYC can drive all aspects of cell growth and cell cycle progression during animal development. MYC is estimated to be dysregulated in over 50% of all cancers, underscoring the importance of elucidating the signals activating MYC. We also discuss the FUBP1/FIR/FUSE system, which acts as a ‘cruise control’ on the MYC promoter to control RNA Polymerase II pausing and, therefore, MYC transcription in response to the developmental signaling environment. Importantly, the striking conservation between humans and flies within these major axes of MYC regulation has made Drosophila an extremely valuable model organism for cancer research. We therefore discuss how Drosophila studies have helped determine the validity of signaling pathways regulating MYC in vivo using sophisticated genetics, and continue to provide novel insight into cancer biology.
Sedative effect of cycloartanol triterpene obtained from Pedilanthus tithymaloides (L.) Poit. leaves.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

INTRODUCTION: Pedilanthus tithymaloides (L.) Poit. (known as itamo real) is a widely distributed plant in Cuba and at the same time a sustainable source of active principles. OBJECTIVE: to evaluate the neurosedative effect of cycloartanol triterpene from dichlorometane extract obtained from Pedilanthus tithymaloides (L.) Poit. leaves. METHODS: models based on exploratory behaviour, barbiturate-induced sleep, pentilenotetrazol-induced seizures and amphetamine-induced stereotyped behaviours were used. Cyclocartanol was orally administered 30 minutes before every test. RESULTS: exploratory behaviour was inhibited at over 50 mg/kg dose; amphetamine-induced stereotyped behaviours were inhibited at 200 mg/kg dose; thiopental-induced sleep was potentiated at over 50 mg/kg dose, however, protection against pentilenotetrazole-induced seizures was not observed. CONCLUSIONS: the results of several tests indicate a depressing effect on the central nervous system of laboratory animal treated with Cycloartanal; however, the sedative effect does not seem to be mediated by the GABAergic system. Antidepressive effects were not observed either.
Acute cerebellar knockdown of Sgce reproduces salient features of myoclonus-dystonia (DYT11) in mice

Field: Neuroscience (Life Sciences)

Myoclonus dystonia (DYT11) is a movement disorder caused by loss-of-function mutations in SGCE and characterized by involuntary jerking and dystonia that frequently improve after drinking alcohol. Existing transgenic mouse models of DYT11 exhibit only mild motor symptoms, possibly due to rodent-specific developmental compensation mechanisms, which have limited the study of neural mechanisms underlying DYT11. To circumvent potential compensation, we used short hairpin RNA (shRNA) to acutely knock down Sgce in the adult mouse and found that this approach produced dystonia and repetitive, myoclonic-like, jerking movements in mice that improved after administration of ethanol. Acute knockdown of Sgce in the cerebellum, but not the basal ganglia, produced motor symptoms, likely due to aberrant cerebellar activity. The acute knockdown model described here reproduces the salient features of DYT11 and provides a platform to study the mechanisms underlying symptoms of the disorder, and to explore potential therapeutic options.

Production of Indole Acetic Acid in Culture by a Rhizobium Species from the Root Nodules of a Monocotyledonous Tree, Roystonea regia

Field: Agricultural and Biological Sciences (Life Sciences)

The study of the rhizobial root nodules of the monocotyledonous tree Roystonea regia revealed that the Rhizobium sp. isolated from the root nodules produced high amounts (45.6 μg/ml) of indole acetic acid (IAA) from L-tryptophan supplemented basal medium. The IAA production reached its optimum using 3 mg/ml of L-tryptophan. The preferred carbon and nitrogen sources were glucose and KNO 3 and the optimum concentrations 1% and 0.02%, respectively. FeSO 4 x 7 H 2 O was found to be the only metal ion that increased IAA production. An optimum IAA production was also achieved when the basal medium was supplemented with glucose (1%), FeSO 4 x 7 H 2 O (10 μg/ml), KNO 3 (0.02%) as well as EDTA (5 μg/ml) and L-tryptophan (3 mg/ml). The possible role of IAA production in the monocotyledonous tree-Rhizobium symbiosis is discussed. Hormone production is shown to be the beneficial aspect of this symbiosis as shown earlier in dicotyledonous plants.
Two Cases of a Unique Variant of Duplicated Extrahepatic Bile Ducts With Coexistence of Distal Klatskin Tumor Surgically Treated by Whipple Procedure and Hepaticojejunostomy

Field: Medicine (Health Sciences)

Duplication of the extrahepatic bile duct (DEHBD) is a rare anomalous of the biliary system. Here we report two unique cases of DEHBD coexistent with hilar cholangiocarcinoma (Klatskin tumor). The two cases were diagnosed preoperatively and treated with a modified surgical technique. Case 1: A 77-year-old female presented with obstructive jaundice. Abdominal computed tomography (CT) scan revealed diffuse bile duct dilatation (BDD). Magnetic resonance cholangiopancreatography (MRCP) showed diffuse BDD, stone in the extrahepatic duct with distal common bile duct (CBD) stricture. Endoscopic retrograde cholangiopancreatography (ERCP) was attempted at other hospital and reported diffuse BDD. The procedure was aborted due to suspected contrast extravasation and the patient was transferred to our facility for further evaluation. Repeated ERCP revealed EHBDD with single biliary drainage to the duodenum (Fig. 1A). Findings were consistent with type Va EHBDD (Fig. 2). Brushing cytology was done. Rapid on-site evaluation (ROSE) by cytopathologist was suggestive of cholangiocarcinoma.Figure 1Figure 2Case 2: A 78-year-old female presented with obstructive jaundice for one month. Abdominal CT showed diffuse BDD. MRCP showed diffuse BDD to the level below CD take off. The patient had ERCP at other facility that showed distal CBD stricture. The stricture was dilated and stented with a 10 French x 5 cm PS. Brush cytology was negative. Patient's jaundice persisted; so she was referred to our institution for further evaluation. Endoscopic ultrasound showed hypoechoic and well-demarcated mass of 21.3x17.2 mm at the neck of pancreas. Fine needle aspiration was done and ROSE by cytopathologist was suggetive of cholangiocarcinoma. Old stent was removed. ERCP was repeated and showed type Va EHBDD(Fig. 1C). The biliary hilum was obstructed by the mass mimicking Klatskin tumor (Fig. 1C). In both cases, biliary strictures were dilated and stented with 2 plastic stents placed up to the right and left main extrahepatic bile ducts (Fig. 1B&D). Both patients were referred for pylorus-preserving Whipple surgery with hepaticojejunostomy. Intra-operative evaluation and surgical pathology confirmed the diagnosis of type Va EHBDD with cholangiocarcinoma involving a distally located biliary hilum (Klatskin tumor) (Fig. 3A&B).Figure 3Preoperative diagnosis of type V EHBDD coexistent with distal hilar cholangiocarcinoma (Klatskin tumor) is challenging and necessitates surgical approach modification. Instead of major hepatic resection or traditional Whipple procedure; Whipple procedure with hepaticojejunostomy was used to manage those potentially resectable Klatskin tumors in the setting of this anomaly.

Deep CNN with batch renormalization based channel estimation algorithms

Field: Computer Science (Physical Sciences)

In recent years, mobile communication technology is developing rapidly, and people's demand for wireless high-speed data communication is increasing day by day. In order to meet the needs of people, some key techniques to enhance the spectrum and energy efficiency are proposed, among which orthogonal frequency division multiplexing (OFDM) technology is a modulation method widely used in wireless broadband systems to combat frequency selective fading in wireless channels. However, the use of higher-order modulation makes the system complex, and more advanced channel estimation techniques are needed to recover the original signal more efficiently at the receiver side. In this paper, the channel transmission matrix is treated as a natural image processing and a deep CNN based denoising network is trained. The network used in this paper has the following advantages: (1) Improving the learning ability of the denoising network by increasing the width instead of the depth. (2) Using the null convolution to expand the perceptual field enables the network to extract more contextual information and reduce the computational cost. (3) Solving the mini-batch problem under hardware resource constrained conditions by Batch renormalization. Also it can accelerate the convergence of the network training. We simulate the OFDM based communication system, and the results prove that the method has excellent performance.

Jejunal diverticulosis: case report of a rare cause of mechanical intestinal obstruction.

Field: Medicine (Health Sciences)

Jejunal diverticulosis is a rare condition and usually discovered incidentally at laparotomy for an unrelated pathology. When inflamed or perforated, jejunal diverticulosis may present with paralytic ileus. In contrast, mechanical bowel obstruction is an unusual presentation. This paper reports the first local case of jejunal diverticulosis presenting with mechanical bowel obstruction due to impaction at the terminal ileum by an enterolith originating from a diverticulum, and reviews the recent literature on the subject.
Teachers' work and gifted education

Field: Social Sciences (Social Sciences)

\n\t\t\t\t\tThis paper examines the perspectives of teachers and personnel working in a State Government primary school situated in the eastern suburbs of Melbourne, four years after participating in the Bright Futures gifted professional development. Although the school proudly proclaims a tradition of scholarship and excellence within a friendly, caring and democratic ethos, the data from semi-structured interviews in a qualitative, single case casestudy, shows considerable ambivalence towards gifted education programs. This has significant negative repercussions for meeting the individual educational needs of gifted students. Using a Foucaultian framework, I analyse the data showing that whilst teachers are striving to improve the learning outcomes for all students, they are caught within a complex reality, created by the often conflicting influences of educational policy, formal school rhetoric and their own personal beliefs, which in turn have been influenced by egalitarian principles detrimental to gifted education.<br />\n\t\t\t\t
