 Type:— INDIA, Peninsula Ind. Orientalis, Herb. Wight Prop. Wight 2691/6 (lectotype E00313794 image!; isolectotype Nagapatam, Wight 6 U1476590 image!, syntypes E00313791 image!; Peninsula Ind. Orientalis, Courtallum, Wight 2691 E00313802 image!, U1476593 image!)
 Piper wightiana Wight Icon 6: t 939. 1853 nom. invalid.
 Distribution:— INDIA: Tamilnadu.
 Note: Remarks by Hooker (1886: 242) about Wight and Arnott’s specimens are very pertinent. A number of specimens collected by Wight with varying numbers or even under the same number under the name Piper wightii are available at U and E. Images of these specimens have been checked. F. A. W. Miquel’s annotations as ‘ Piper wightii n. sp. ’ are found on two specimens, one each at U and E, but with slight differences in numbering and labelling but essentially having the number Wight 6. Both are equally good specimens matching the description by Miquel. Of these Wight n. 2691/6, E (00313794) is designated here as the lectotype, and Wight 6 is selected as the isolectotype. Miquel cited two localities in Peninsular India, Nagapatam and Courtallum. Hence, Wight’s Specimens from Peninsular India, Courtallum, mentioned by Wight (1853) and matching the description are recognised here as syntypes.
 A number of Wight’s specimens at E often have different plants stored under that name. Some of them match with P. argyrophyllum Miq., P. hymenophyllum, or P. hookeri Miq. besides P. wightii itself as correctly noted by Hooker (loc. cit.). Gamble incorrectly identified several of them as P. attenuatum. Wight’s specimens at K are excluded from consideration of typification as only one of them has the mention of locality as Coonoor and this has not been mentioned by Miquel. The name P. wightiana ascribed to Wight (Pl. 1939 of Wight’s Icon) was an error by his (1853:4) own admission. Miquel (1856: 553) suggested forma glabrior for specimens from Dindigul and Courtallum, having glabrous 5-nerved leaves, without formally publishing the combination.

description: Aqueous solutions of 4,4′-(1,2-ethanediyldinitrilo)bis-(2-pentanone) (EDDBP) have been used in a novel green procedure for the physical modification of silica gel (SG) for solid-phase extraction and preconcentration of Ni(II) ion. Optimization experiments were carried out at 301 ± 1 K by batch technique. The EDDBP-modified SG was characterized using X-ray Diffraction Spectroscopy (XRD) and Brunaeur-Emmett-Teller (BET) determinations. The adsorption isotherm and kinetic models indicated a physisorption process. The modified SG showed moderate to high adsorption capacity values for Ni(II) ion (~98% removal efficiency) at pH 8. A sorption mechanism for Ni(II) chelation with EDDBP-modified-SG was proposed. These results suggest the procedure has advantages.

description: With the rising quantity of textual data available in electronic format, the need to organize it become a highly challenging task. In the present paper, we explore a document organization framework that exploits an intelligent hierarchical clustering algorithm to generate an index over a set of documents. The framework has been designed to be scalable and accurate even with large corpora. The advantage of the proposed algorithm lies in the need for minimal inputs, with much of the hierarchy attributes being decided in an automated manner using statistical methods. The use of topic modeling in a pre-processing stage ensures robustness to a range of variations in the input data. For experimental work 20-Newsgroups dataset has been used. The F- measure of the proposed approach has been compared with the traditional K-Means and K-Medoids clustering algorithms. Test results demonstrate the applicability, efficiency and effectiveness of our proposed approach. After extensive experimentation, we conclude that the framework shows promise for further research and specialized commercial applications.

Marginal Pricing and Student Investment in Higher Education

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This paper examines the effect of marginal price on students' educational investments using rich administrative data on students at Michigan public universities. Marginal price refers to the amount colleges charge for each additional credit taken in a semester. Institutions differ in how they price credits above the full-time minimum (of 12 credits), with many institutions reducing the marginal price of such credits to zero. We find that a zero marginal price induces a modest share of students (i.e., 7 percent) to attempt up to one additional class (i.e., three credits) but also increases withdrawals and lowers course performance. The analysis generally suggests minimal impacts on credits earned and the likelihood of meeting "on-time" benchmarks toward college completion, though estimates for these outcomes are less precise and more variable across specifications. Consistent with theory, the effect on attempted credits is largest among students who would otherwise locate at

Reversible shape-shifting in polymeric materials

Year: 2016

description: In recent years, significant progress has been made in polymeric materials, which alter shape upon external stimuli, suggesting potential applications in robotics, biomedical engineering, and optical devices. These stimuli‐responsive materials may be categorized into two classes: (i) shape‐changing materials in which a specific type of shape‐shifting is encoded in the original material structure and (ii) shape‐memory materials, which do not possess any predetermined shape‐shifting as prepared, yet allow programming of complex shape transformations on demand. While shape alterations in shape‐changing materials are intrinsically reversible, shape memory is usually a one‐way transformation from a metastable (programmed) to an equilibrium (original) state. Recently, different principles for both one‐way reversible and two‐way reversible shape memory have been developed. These offer a powerful combination of reversibility and programmability, which significantly expands the range of potential applications. The goal of this review is to highlight recent developments in reversible shape‐shifting by introducing novel mechanisms, materials, and applications. © 2016 Wiley Periodicals, Inc. J. Polym.

description: The direction of the steady-state heat currents across a generic quantum system connected to multiple baths may be engineered so as to realize virtually any thermodynamic cycle. In spite of their versatility such continuous energy-conversion systems are generally unable to operate at maximum efficiency due to non-negligible sources of irreversible entropy production. In this paper we introduce a minimal model of irreversible absorption chiller. We identify and characterize the different mechanisms responsible for its irreversibility, namely heat leaks and internal dissipation, and gauge their relative impact in the overall cooling performance. We also propose reservoir engineering techniques to minimize these detrimental effects. Finally, by looking into a known three-qubit embodiment of the absorption cooling cycle, we illustrate how our simple model may help to pinpoint the different sources of irreversibility naturally arising in more complex practical heat devices.

description: Vibrio metschnikovii is an emergent pathogen that causes human infections which may be fatal. However, the phylogenetic characteristics and pathogenicity determinants of V. metschnikovii are poorly understood. Here, the whole-genome features of 103 V. metschnikovii strains isolated from different sources are described. On phylogenetic analysis V. metschnikovii populations could be divided into two major lineages, defined as lineage 1 (L1) and 2 (L2), which L1 was more likely to be associated with human activity. Meanwhile, we defined 29 V. metschnikovii O-genotypes (VMOg, named VMOg1–VMOg29) by analysis of the O-antigen biosynthesis gene clusters (O-AGCs). Most VMOgs (VMOg1 to VMOg28) were assembled by the Wzx/Wzy pathway, while only VMOg29 used the ABC transporter pathway. Based on the sequence variation of the wzx and wzt genes, an in silico O-genotyping system for V. metschnikovii was developed. Furthermore, nineteen virulence-associated factors involving 161 genes were identified within the V. metschnikovii genomes, including genes encoding motility, adherence, toxins, and secretion systems. In particular, V. metschnikovii was found to promote a high level of cytotoxicity through the synergistic action of the lateral flagella and T6SS. The lateral flagellar-associated flhA gene played an important role in the adhesion and colonization of V. metschnikovii during the early stages of infection. Overall, this study provides an enhanced understanding of the genomic evolution, O-AGCs diversity, and potential pathogenic features of V. metschnikovii.

description: The importance of membrane proteins in biological systems is indisputable; however, their amphipathic nature makes them difficult to analyze. In this study, the most popular techniques for extraction, enrichment, solubilization, and digestion are compared, resulting in an overall improved workflow for the insoluble portion of Saccharomyces cerevisiae cell lysate. Yeast cells were successfully lysed using a French press pressure cell at 20 000 psi, and resulting proteins were fractionated prior to digestion to reduce sample complexity. The proteins were best solubilized with the addition of ionic detergent sodium deoxycholate (1%) and through the application of high-frequency sonication prior to a tryptic digestion at 37 °C. Overall, the improved membrane proteomic workflow resulted in a 26% increase in membrane protein identifications for baker's yeast. In addition, more membrane protein identifications were unique to the improved protocol. When comparing membrane proteins that were identified in the improved protocol and the standard operating procedure (176 proteins), 93% of these proteins were present in greater abundance (higher intensity) when using the improved method.

description: We explore the galaxy formation physics governing the low mass end of the HI mass function in the local Universe. Specifically, we predict the effects on the HI mass function of varying i) the strength of photoionisation feedback and the redshift of the end of the epoch of reionization, ii) the cosmology, iii) the supernovae feedback prescription, and iv) the efficiency of star formation. We find that the shape of the low-mass end of the HI mass function is most affected by the critical halo mass below which galaxy formation is suppressed by photoionisation heating of the intergalactic medium. We model the redshift dependence of this critical dark matter halo mass by requiring a match to the low-mass end of the HI mass function. The best fitting critical dark matter halo mass decreases as redshift increases in this model, corresponding to a circular velocity of $\sim 50 \, {\rm km \,s}^{-1}$ at $z=0$, $\sim 30 \, {\rm km\, s}^{-1}$ at $z \sim 1$ and $\sim 12 \, {\rm km \, s}^{-1}$ at $z=6$. We find that an evolving critical halo mass is required to explain both the shape and abundance of galaxies in the HI mass function below $M_{\rm HI} \sim 10^{8} h^{-2} {\rm M_{\odot}}$. The model makes specific predictions for the clustering strength of HI-selected galaxies with HI masses > $10^{6} h^{-2} {\rm M_{\odot}}$ and $> 10^{7} h^{-2} {\rm M_{\odot}}$ and for the relation between the HI and stellar mass contents of galaxies which will be testable with upcoming surveys with the Square Kilometre Array and its pathfinders. We conclude that measurements of the HI mass function at $z \ge 0$ will lead to an improvement in our understanding of the net effect of photoionisation feedback on galaxy formation and evolution.

description: A time-domain numerical modeling of transversely isotropic Biot poroelastic waves is proposed in two dimensions. The viscous dissipation occurring in the pores is described using the dynamic permeability model developed by Johnson-Koplik-Dashen (JKD). Some of the coefficients in the Biot-JKD model are proportional to the square root of the frequency. In the time-domain, these coefficients introduce shifted fractional derivatives of order 1/2, involving a convolution product. Based on a diffusive representation, the convolution kernel is replaced by a finite number of memory variables that satisfy local-in-time ordinary differential equations, resulting in the Biot-DA (diffusive approximation) model. The properties of both the Biot-JKD and the Biot-DA model are analyzed: hyperbolicity, decrease of energy, dispersion. To determine the coefficients of the diffusive approximation, two approaches are analyzed: Gaussian quadratures and optimization methods in the frequency range of interest. The nonlinear optimization is shown to be the better way of determination. A splitting strategy is then applied to approximate numerically the Biot-DA equations. The propagative part is discretized using a fourth-order ADER scheme on a Cartesian grid, whereas the diffusive part is solved exactly. An immersed interface method is implemented to take into account heterogeneous media on a Cartesian grid and to discretize the jump conditions at interfaces. Numerical experiments are presented. Comparisons with analytical solutions show the efficiency and the accuracy of the approach, and some numerical experiments are performed to investigate wave phenomena in complex media, such as multiple scattering across a set of random scatterers.

Αυτό το νέο παράδειγμα έχει κάνει τις παραδοσιακές αμυντικές λύσεις ανίκανες να αντιμετωπίσουν την ανάπτυξη των κυβερνοεπιθέσεων και έτσι έχουν εμφανιστεί νέες άμυνες που εκμεταλλεύονται την αποτελεσματικότητα των συστημάτων Τεχνητής Νοημοσύνης.

Αφού αναγνωρίσαμε ότι τα συστήματα Τεχνητής Νοημοσύνης μπορούν να προστατευτούν, αυτή η διατριβή επικεντρώθηκε στο σχεδιασμό και την ανάπτυξη αμυντικών μεθοδολογιών Μηχανικής Μάθησης έναντι δύο γνωστών κυβερνοεπιθέσεων, γνωστών ως phishing και exploit kit. Τα πειραματικά αποτελέσματα έδειξαν ότι οι προτεινόμενες μεθοδολογίες, συνολικά, βελτίωσαν την απόδοση ανίχνευσης επιθέσεων phishing και exploit kit, καταλήγοντας στο συμπέρασμα ότι η Μηχανική Μάθηση μπορεί να χρησιμοποιηθεί για να σταματήσει τη συνεχιζόμενη απειλή των κυβερνοεπιθέσεων.

description: The NCI Clinical Proteomic Tumor Analysis Consortium (CPTAC) employed a pair of reference xenograft proteomes for initial platform validation and ongoing quality control of its data collection for The Cancer Genome Atlas (TCGA) tumors. These two xenografts, representing basal and luminal-B human breast cancer, were fractionated and analyzed on six mass spectrometers in a total of 46 replicates divided between iTRAQ and label-free technologies, spanning a total of 1095 LC–MS/MS experiments. These data represent a unique opportunity to evaluate the stability of proteomic differentiation by mass spectrometry over many months of time for individual instruments or across instruments running dissimilar workflows. We evaluated iTRAQ reporter ions, label-free spectral counts, and label-free extracted ion chromatograms as strategies for data interpretation (source code is available from http://homepages.uc.edu/~wang2x7/Research.htm). From these assessments, we found that differential genes from a single replicate were confirmed by other replicates on the same instrument from 61 to 93% of the time. When comparing across different instruments and quantitative technologies, using multiple replicates, differential genes were reproduced by other data sets from 67 to 99% of the time. Projecting gene differences to biological pathways and networks increased the degree of similarity. These overlaps send an encouraging message about the maturity of technologies for proteomic differentiation.

description: We consider the quantum witness test of macroscopic realism and derive an upper bound for possible violations of this equality due to quantum mechanics. The bound depends only on the number of possible outcomes for the blind measurement at the heart of the witness protocol. Mirroring recent results for the related Leggett-Garg inequality, we show that quantum mechanics can saturate the algebraic bound for large systems. We also establish a connection between the quantum witness and the trace distance between density matrices.

description: Two-dimensional (2D) topological insulators (TIs) hold promise for applications in spintronics based on the fact that the propagation direction of edge electrons of a 2D TI is robustly linked to their spin origination. Here, with the use of first-principles calculations, we predict a family of robust 2D TIs in monolayer square transition metal dichalcogenides (MoS2, MoSe2, MoTe2, WS2, WSe2, and WTe2). Sizeable intrinsic nontrivial bulk band gaps ranging from 24 to 187 meV are obtained, guarantying the quantum spin Hall (QSH) effect observable at room temperature in these new 2D TIs. Significantly different from most known 2D TIs with comparable band gaps, these sizeable energy gaps originate from the strong spin-orbit interaction related to the pure d electrons of the Mo/W atoms around the Fermi level. A single pair of topologically protected helical edge states is established for the edge of these systems with the Dirac point locating in the middle of the bulk band gap, and their topologically nontrivial states are also confirmed with nontrivial topological invariant Z2 = 1. More interestingly, by controlling the applied strain, a topological quantum phase transition between a QSH phase and a metallic phase or a trivial insulating phase can be realized in these 2D materials, and the detailed topological phase diagram is established.

description: Lens modeling of resolved image data has advanced rapidly over the past two decades. More recently pixel-based approaches, wherein the source is reconstructed on an irregular or adaptive grid, have become popular. Generally, the source reconstruction takes place in a Bayesian framework and is guided by a set of sensible priors. We discuss the integration of a shapelets-based method into a Bayesian framework and quantify the required regularization. In such approaches, the source is reconstructed analytically, using a subset of a complete and orthonormal set of basis functions, known as shapelets. To calculate the flux in an image plane pixel, the pixel is split into two or more triangles (depending on the local magnification), and each shapelet basis function is integrated over the source plane. Source regularization (enforcement of priors on the source) can also be performed analytically. This approach greatly reduces the number of source parameters from the thousands to hundreds and results in a posterior probability distribution that is much less noisy than pixel-based approaches.

description: BACKGROUND: Substantial proportions of US residents in the USA-Mexico border region cross into Mexico for health care; increases in violence in northern Mexico may have affected this access. We quantified associations between violence in Mexico and decreases in access to care for border county residents. We also examined associations between border county residence and access.

METHODS: We used hospital inpatient data for Arizona, California and Texas (2005-10) to estimate associations between homicide rates and the probability of hospitalization for ambulatory care sensitive (ACS) conditions. Hospitalizations for ACS conditions were compared with homicide rates in Mexican municipalities matched by patient residence.

RESULTS: A 1 SD increase in the homicide rate of the nearest Mexican municipality was associated with a 2.2 percentage point increase in the probability of being hospitalized for an ACS condition for border county patients. Residence in a border county was associated with a 1.3 percentage point decrease in the probability of being hospitalized for an ACS condition.

CONCLUSIONS: Increased homicide rates in Mexico were associated with increased hospitalizations for ACS conditions in the USA, although residence in a border county was associated with decreased probability of being hospitalized for an ACS condition. Expanding access in the border region may mitigate these effects by providing alternative sources of care.

description: We describe an automatic event recognition (AER) system based on a three-dimensional spatio-temporal correlator (STC) that combines the techniques of holographic correlation and photon echo based temporal pattern recognition. The STC is shift invariant in space and time. It can be used to recognize rapidly an event (e.g., a short video clip) that may be present in a large video file, and determine the temporal location of the event. Using polar Mellin transform, it is possible to realize an STC that is also scale and rotation invariant spatially. Numerical simulation results of such a system are presented using quantum mechanical equations of evolution. For this simulation we have used the model of an idealized, decay-free two level system of atoms with an inhomogeneous broadening that is larger than the inverse of the temporal resolution of the data stream. We show how such a system can be realized by using a lambda-type three level system in atomic vapor, via adiabatic elimination of the intermediate state. We have also developed analytically a three dimensional transfer function of the system, and shown that it agrees closely with the results obtained via explicit simulation of the atomic response. The analytical transfer function can be used to determine the response of an STC very rapidly. In addition to the correlation signal, other nonlinear terms appear in the explicit numerical model. These terms are also verified by the analytical model. We describe how the AER can be operated in a manner such that the correlation signal remains unaffected by the additional nonlinear terms. We also show how such a practical STC can be realized using a combination of a porous-glass based Rb vapor cell, a holographic video disc, and a lithium niobate crystal.

description: Innovative models to facilitate more rapid uptake of research findings into practice are urgently needed. Community members who engage in research can accelerate this process by acting as adoption agents. We implemented an Evidence Academy conference model bringing together researchers, health professionals, advocates, and policy makers across North Carolina to discuss high-impact, life-saving study results. The overall goal is to develop dissemination and implementation strategies for translating evidence into practice and policy. Each one-day, single-theme, regional meeting focuses on a leading community-identified health priority. The model capitalizes on the power of diverse local networks to encourage broad, common awareness of new research findings. Furthermore, it emphasizes critical reflection and active group discussion on how to incorporate new evidence within and across organizations, health care systems, and communities. During the concluding session, participants are asked to articulate action plans relevant to their individual interests, work setting, or area of expertise.

description: Colloidal assembly represents a powerful method for the fabrication of functional materials. In this article, we describe how acoustic radiation forces can guide the assembly of colloidal particles into structures that serve as microscopic elements in novel acoustic metadevices or act as phononic crystals. Using a simple three-dimensional orthogonal system, we show that a diversity of colloidal structures with orthorhombic symmetry can be assembled with megahertz-frequency (MHz) standing pressure waves. These structures allow rapid tuning of acoustic properties and provide a new platform for dynamic metamaterial applications.

description: Institutional Pedagogy is a pedagogic trend born in France in the 1950s. This trend is the result of a fruitful encounter between Institutional Psychotherapy and Célestin Freinet’s pedagogy. At this time, the field of mental health was involved in debates about the way patients were taken care of, treated and considered in general. A critical movement was growing all over the world, and some edifying testimonies and critics have since then illustrated this debate.

description: This paper is concerned with variational methods for nonlinear open quantum systems with Markovian dynamics governed by Hudson-Parthasarathy quantum stochastic differential equations. The latter are driven by quantum Wiener processes of the external boson fields and are specified by the system Hamiltonian and system-field coupling operators. We consider the system response to perturbations of these energy operators and introduce a transverse Hamiltonian which encodes the propagation of the perturbations through the unitary system-field evolution. This provides a tool for the infinitesimal perturbation analysis and development of optimality conditions for coherent quantum control problems. We apply the transverse Hamiltonian variational technique to a mean square optimal coherent quantum filtering problem for a measurement-free cascade connection of quantum systems.

description: We evaluated the effects of marital dissatisfaction on adolescent-perceived conflict in 435 families with and without a parental history of alcoholism. On average, family conflict decreased linearly as adolescents aged. Families with an alcoholic parent demonstrated higher adolescent-reported family conflict and this effect was partially mediated by higher mother- and father-reported marital dissatisfaction. Families with higher marital dissatisfaction had greater conflict when adolescents were young (based on fathers' marital dissatisfaction) and as they aged (based on mother's marital dissatisfaction). Years in which mothers reported higher marital dissatisfaction than usual coincided with years in which adolescents reported greater family conflict. Results indicate that marital dissatisfaction has both within and between-family effects on adolescent perceptions of conflict.
