PO-0485 Cerebral Blood Flow And Oxygenation Changes Following Blood Transfusion In Preterm Infants

Background and aims We have shown blood transfusion (BT) significantly reduces cerebral blood flow and improves cerebral tissue oxygenation in preterm infants during the first week of life . 1 Aim To study the effect of BT on cerebral blood flow and oxygenation during the 2nd to 4th week of life in preterm infants. Methods Pre and post-BT Anterior Cerebral Artery (ACA) peak systolic velocity, mean velocity, resistance index (RI) and pulsatility index (PI), and Superior Vena Cava (SVC) flow were measured using Doppler USS. Pre, during and post-BT cerebral oxygenation were measured using Near Infra-Red Spectroscopy (NIRO 300). Pre and post-BT measurements were compared by paired t-test using SPSS 22.0. Results 21 preterm infants with median (range) gestational age of 25(23–30) weeks, birth weight 805(630–1250) grams, chronological age 14(8–27) days and pre-BT Haemoglobin 10.3(7.7–12.2) g/dl were studied. Pre-BT ACA peak systolic (0.37 m/s) and mean velocity (0.19 m/s) decreased significantly post-BT (0.32 and 0.16 respectively; p < 0.01). There was no significant change in RI (p = 0.57) and PI (p = 0.53) in the ACA and SVC flow (p = 0.16) post-BT. The cerebral HbO2 increased significantly (mean difference 12.53 µM; p < 0.001) post-BT. The pre-BT mean cerebral tissue oxygenation index (TOI) (66.5%) increased significantly post-BT (73.6%; p < 0.001). Conclusion The cerebral blood flow velocity decreased but there was no change in SVC flow volume; cerebral tissue oxygenation improved following BT during the 2nd to 4th week of life in preterm infants.

Isolation, purification and physicochemical properties of the polysaccharide FI from Aconitum carmichaeli Debx

The Polysaccharide FI were isolated from Aconitum carmichaeli Debx through water extraction, deproteining, ethanol precipitating, DEAE-cellulose column chromatography. FI was further purified by Sephadex G-200 column chromatography. The content of total sugar, the average MW and the melting point of the Polysaccharide were 97%, 2.6X10~(5) and 270deg C respectively. The data of IR revealed that FI is chiefly linged by beta-glycosidic bonds. Chemical composition analysis by TLC showed that FI is composed of glucose.
Co-occurrence patterns of rodents at multiple spatial scales: competitive release of generalists following habitat loss?

Theory predicts that habitat generalist species are excluded by specialist species in optimal habitat for specialists, and empirical data commonly show a shift from specialist- to generalist-dominated communities following disturbance. We investigated co-occurrence patterns of habitat generalist and specialist terrestrial rodents at two spatial scales in the Atlantic Forest, aiming at evaluating the following hypotheses: 1) within-patch spatial niche partitioning promotes coexistence of generalists and specialists, leading to checkerboard presence-absence patterns at small (within-patch) rather than large (among-patch) scales; and 2) the decrease in abundance of specialists due to habitat loss promotes a competitive release of generalists, leading to negative covariance in abundance between generalists and specialists among patches. Drawing on a large data set including 363 sites within three patches in continuous forest, and 45 patches within three landscapes, we used C-scores based on presence-absence and abundance data to evaluate spatial segregation. We found consistent segregation between specialists and generalists at the within-patch rather than among-patch scale, but no consistent negative covariance in abundance between generalists and specialists among patches (as covarying species pairs varied across landscapes). Our findings suggest that spatial patterns caused by competition are scale-dependent, and coexistence of generalists and specialists is promoted by within-patch spatial niche partitioning. However, the influence of competitive release on the proliferation of generalists may be outweighed by other factors in fragmented landscapes.
The complete chloroplast genome of Paulownia elongata and phylogenetic implications in Lamiales

Abstract Paulownia elongata (Paulowniaceae) is an ornamental tree native to Asia. In this study, the chloroplast (cp) genome of P. elongata was assembled using genome skimming sequencing, and the phylogeny of Lamiales was reconstructed based on whole cp genome data. The cp genome of P. elongata is 154,670 bp in length, comprising two copies of inverted region (IR, 25,783 bp), regions separated by the large single copy (LSC, 85,370 bp) and small single copy (SSC, 17,734 bp) regions. The cp genome encodes 114 unique genes, including 80 different protein-coding genes, 30 tRNA genes, and four rRNA genes, with 19 duplicated genes in the IR regions. Phylogenetic analysis indicates that P. elongata together with two other Paulownia species form a clade, which is sister to Triaenophora shennongjiaensis.
A 10-MHz Hysteretic-Controlled Buck Converter With Single On/Off Reference Tracking Using Turning-Point Prediction for DVFS Application

This paper presents a turning-point output voltage (TPOV) prediction method to enhance the reference tracking speed of buck converters for dynamic voltage and frequency scaling (DVFS) application. The optimal reference tracking is modeled, and the TPOV is formulated. The parasitic effects are compensated with the proposed calibration scheme. Reference tracking considering load current changes is evaluated with the proposed end-point determination method. Additionally, this work optimizes the feedback network for smooth loop transition, and incorporates the frequency-locking circuit and the error correction path to address the shortcomings of the hysteretic control. The prototype is fabricated in a 0.13-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> CMOS process with a 1.2-V supply voltage. The converter achieves a near-optimum reference tracking over a wide range of output voltages, from 0.5 to 1 V. Various output voltage steps are measured for different load cases. For a 0.5–1-V output voltage step, with a 90-nH inductor and a 1-<inline-formula> <tex-math notation="LaTeX">$\mu \text{F}$ </tex-math></inline-formula> output capacitor, the up- and down-tracking take 558 and 542 ns, respectively, matching the theoretical result of 533 ns. The prototype achieves a peak efficiency of 93.5%, and over 85% efficiency is measured with <inline-formula> <tex-math notation="LaTeX">$\mathrm {V}_{\mathrm {O}}$ </tex-math></inline-formula> from 0.5 to 1 V and <inline-formula> <tex-math notation="LaTeX">$\mathrm {I}_{\mathrm {O}}$ </tex-math></inline-formula> from 130 to 550 mA.

Vegetative Propagation of Mountain Fly Honeysuckle (Lonicera villosa) by Overhead Mist and Subirrigation

We assessed adventitious root formation on stem cuttings of mountain fly honeysuckle [Lonicera villosa (Michx.) Schult. ] in separate experiments using overhead mist and subirrigation systems. The concentration of applied potassium salt of indole-3-butyric acid (K-IBA) and the proportions of coarse perlite and milled peatmoss in the propagation medium were varied within both systems. Across treatments, 98% of cuttings in the overhead mist system and 85% of cuttings in the subirrigation system produced roots. In the overhead mist system, root volume, root dry weight, and number of root tips were greatest among cuttings treated with 4000 to 12,000 mg·L−1 K-IBA and stuck into 100% perlite. In the subirrigation system, root dry weight was not significantly affected by K-IBA concentration, but the greatest root volume and number of root tips were produced by cuttings treated with 8000 or 12,000 mg·L−1 K-IBA and stuck into 100% perlite. Despite the natural affinity of mountain fly honeysuckle for moist, organic soils, all of the 18 rooted cuttings we planted in a landscape trial survived and grew appreciably with minimal care over 2 years in a mineral field soil. We conclude that cuttings of mountain fly honeysuckle can be propagated readily by overhead mist or subirrigation, that root system quality is improved substantially by increasing K-IBA concentration and using coarse perlite without peatmoss, and that mountain fly honeysuckle can be grown in typical horticultural landscapes.
Double-way Authentication Scheme Based on ELGamal Digital Signature

Aiming at the problems of low authentication efficiency and its complex process, a double-way authentication scheme of ELGamal digital signature is proposed. The Key Distribution Center(KDC) is introduced as the third aspect, which distributes the public keys and communicates with both sides. Analysis results show this scheme improves the complexity than discrete logarithm and the computing efficiency is better than others. The scheme may have some comprehensive application in identification and digital signature.

Entomoparasitic nematodes of the genus Skarbilovinema: S. laumondi and S. lyoni (Nematoda: Tylenchida), parasites of the flies of the family Syrphidae (Diptera), with phylogeny of the suborder Hexatylina

Morphological description of two entomoparasitic nematodes, Skarbilovinema laumondi and S. lyoni, parasitising flies from the genus Helophilus and Eristalis of the family Syrphidae (Diptera) are given. The life cycle of these nematodes is also presented. Phylogenetic analysis using the D2-D3 expansion fragments of the 28S rRNA gene and partial 18S rRNA gene sequences showed that Skarbilovinema has a sister relationships with Fergusoria sp. Sequence analysis revealed an anomalous mode of evolution for the ribosomal RNA genes in Skarbilovinema, which have long insertions, strong AT nucleotide content bias and a high mutation rate. Difference in the D2-D3 expansion segments of 28S rRNA gene sequences between S. laumondi and S. lyoni was 23%, which is higher than usual sequence variation for nematode species belonging to same genus. Several long insertions make 18S rRNA gene and the D2-D3 of 28S rRNA gene the longest ribosomal rRNA genes in nematodes.
Environmental stress effects on the phytochemistry and bioactivity responses of a South African medicinal bulbous plant, Tulbaghia violacea Harvey (Alliaceae)

Environmental stress factors such as high or low soil pH, water deficit, high temperature and shade may result in accumulation of reactive oxygen species in plants, which in turn may cause oxidative stress when in excess. This study was divided into two separate preliminary experiments. Simultaneous assessments of the effects of i) varied pH levels (pH 4, pH 6, pH 8) and ii) low light intensity and normal light intensity on plant growth, antioxidant-content and -capacity of extracts of T. violacea. The objectives of this exploratory preliminary study were to assess the effects of abiotic environmental stresses (pH, normal light and low light) on the antioxidant-content and -capacity of T. violacea under greenhouse conditions. Observations were recorded on the following parameters: plant height, plant fresh and dry weights, antioxidant-content and -capacity. Plant height was recorded weekly, and at twomonth post-treatment, plants were harvested and fresh and dry weights were recorded. Dried aerial and root parts were analysed for antioxidant-content and -capacity. Results obtained from the first part of the study showed that plants exposed to pH 6 showed a marked increase in plant height (from 25-37 cm) after 2 months of treatment; although, generally, the variations in growth parameters among the different pH treatments were not significant (p > 0.05). Antioxidant-content and -capacity were not significantly different (p > 0.05) when pH treatments were compared. However, a high polyphenol content value (3 mg/g) was found in leaves of plants exposed to pH 8. Flavonol content was 2.3 mg/g in the roots exposed to pH 4. Overall, there was no significant difference (p > 0.05) in antioxidant-content and -capacity when pH treatments were compared. On the light experiment, it was observed that decreasing light intensity from normal to low light led to the elongation of plant height from 34.6-26.5 cm, as well as lower weight gain in the roots and leaves of plants. Higher leaf polyphenol content was obtained in plants grown under normal light intensity and those exposed to low light intensity. The polyphenol and flavonol content fluctuated between the averages of 5.8 ± 0.2 mg/g to 8.5 ± 0.3 mg/g. In conclusion, besides flavonol, increased leaf antioxidantcontent and -capacity were produced by exposing T. violacea to normal light intensity. Meanwhile, pH 8 plants, in general, had increased antioxidant-content and -capacity levels.
Zero‐order asymptotic solution of a class of singularly perturbed linear‐quadratic problems with weak controls in a critical case

We consider a linear‐quadratic optimal control problem where the second power of a small parameter stands in front of the derivative and a control in a state equation and in front of a quadratic form with respect to control in a performance index; moreover, in the state equation, the nonhomogeneity has the first order of the power of a small parameter, and a matrix in front of the state variable is singular if the small parameter is equal to zero. Using immediate substituting a postulated asymptotic expansion of a solution, containing a regular series and four boundary layer functions series, into the problem condition, we obtain problems for finding asymptotic terms of the zero order for the optimal control and the first order for the optimal trajectory. An illustrative example is given.
Injection Treatments for Killing Bottom-Land Hardwoods

Injection of undiluted dimethylamine salt of (2,4-dichlorophenoxy)acetic acid (2,4-D) containing 479 g/L killed several species of bottom-land hardwoods when applied in 1 or 2-ml dosages in injections spaced from edge-to-edge to 23 cm apart. Most hardwoods were easier to kill in June than in September or December. For greatest economy, treatments should be varied by species and seasons. A 4:1 mixture of triisopropanolamine salts of 2,4-D and 4-amino-3,5,6-trichloropicolinic acid (picloram) containing 305 g/L was effective on some species resistant to 2,4-D, including eastern persimmon (Diospyros virginiana L.), swamp privet (Forestiera acuminata (Michx.)Poir. ), and bitter pecan (Carya x lecontei Little).
Neutrophils promote CXCR3-dependent itch in the development of atopic dermatitis

Chronic itch remains a highly prevalent disorder with limited treatment options. Most chronic itch diseases are thought to be driven by both the nervous and immune systems, but the fundamental molecular and cellular interactions that trigger the development of itch and the acute-to-chronic itch transition remain unknown. Here, we show that skin-infiltrating neutrophils are key initiators of itch in atopic dermatitis, the most prevalent chronic itch disorder. Neutrophil depletion significantly attenuated itch-evoked scratching in a mouse model of atopic dermatitis. Neutrophils were also required for several key hallmarks of chronic itch, including skin hyperinnervation, enhanced expression of itch signaling molecules, and upregulation of inflammatory cytokines, activity-induced genes, and markers of neuropathic itch. Finally, we demonstrate that neutrophils are required for induction of CXCL10, a ligand of the CXCR3 receptor that promotes itch via activation of sensory neurons, and we find that that CXCR3 antagonism attenuates chronic itch.

An autoencoder‐based piecewise linear model for nonlinear classification using quasilinear support vector machines

In this paper, we propose to implement a piecewise linear model to solve nonlinear classification problems. In order to realize a switch between linear models, a data‐dependent gating mechanism achieved by an autoencoder is designed to assign gate signals automatically. We ensure that a diversity of gate signals is available so that it is possible for our model to switch between a large number of linear classifiers. Besides, we also introduce a sparsity level to add a manual control on the flexibility of the proposed model by using a winner‐take‐all strategy. Therefore, our model can maintain a balance between underfitting and overfitting problems. Then, given a learned gating mechanism, the proposed model is shown to be equivalent to a kernel machine by deriving a quasilinear kernel function with the gating mechanism included. Therefore, a quasilinear support vector machine can be applied to solve the nonlinear classification problems. Experimental results demonstrate that our proposed piecewise linear model performs better than or is at least competitive with its state‐of‐the‐art counterparts. © 2019 Institute of Electrical Engineers of Japan.

Data‐driven wind speed forecasting using deep feature extraction and LSTM

Wind speed forecasting is important for high-efficiency utilisation of wind energy and management of grid-connected power systems. Due to the noise, instability and irregularity of atmosphere system, the current models based on raw historical data have encountered many problems. In this study, a deep novel feature extraction approach is developed based on stacked denoising autoencoders and batch normalisation. Then the deep features extracted from raw historical data are fed to long short-term memory (LSTM) neural networks for prediction. Meanwhile, density-based spatial clustering of applications with noise is employed to process the numerical weather prediction data. By picking out the abnormal samples, the representative training samples are selected to improve the efficiency of the model. For illustration and verification purposes, the proposed model is used to predict the wind speed of Wind Atlas for South Africa (WASA). Empirical results show that deep feature extraction can improve the forecasting accuracy of LSTM 49% than feature selection, indicating that proper feature extraction is crucial to wind speed forecasting. And the proposed model outperforms other benchmark methods at least 17%. Hence, the proposed model is promising for wind speed forecasting.
Cascaded Pumping Cycle Control for Rigid Wing Airborne Wind Energy Systems

Airborne wind energy is an emerging technology that uses tethered unmanned aerial vehicles for harvesting wind energy at altitudes higher than conventional towered wind turbines. To make the technology competitive to other renewable energy technologies a reliable control system is required that allows autonomously operating the system throughout all phases of flight. In the present work a cascaded nonlinear control scheme for reliable pumping cycle control of a rigid wing airborne wind energy system is proposed. The high-level control strategy in the form of a state machine as well as the flight controller consisting of path-following guidance and control, attitude, and rate loop is presented along with a winch controller for tether force tracking. Amathematical model for an existing prototype will be derived, and results from a simulation study will be used to demonstrate the robustness of the proposed concept in the presence of turbulence and wind gusts.
