Information Frictions and Stock Returns

The purpose of this paper is to assess the impact of ambiguity on financial analyst forecast incentives and the associated abnormal stock returns. I present a model incorporating ambiguity aversion into a two-period Lucas tree model. The resulting model confirms the role of ambiguity in the determination of asset returns. In particular, the model with ambiguity aversion generates a lower price and a higher required rate of returns compared to the classical model without ambiguity concern. I construct a measure of ambiguity and provide empirical evidence showing that the incentive of analysts to misrepresent information is a function of ambiguity. Analysts are more likely to bias their forecasts when it is more difficult for investors to detect their misrepresentation. Under ambiguity, analysts’ optimistic forecasts for good/bad news tend to deteriorate. Moreover, stock returns are positively related with ambiguity. Under ambiguity neither good nor bad news is credible. Investors systematically underreact to good news forecast and overreact to bad news forecast when ambiguity exists.
Composition of Methods to Ensure Iris Liveness and Authenticity

In a biometric system technology, a person is authenticated based on processing the unique features of the human biometric signs. One of the well known biometric systems is iris recognition, this technique being considered as one of the most secure authentication solutions in the biometric ﬁeld. However, several attacks do exist that are able to spoof iris. In this paper, we propose a novel approach for securing the iris recognition system by eye liveness detection technique. The proposed system detects the eye liveness, and recognises the iris. This process includes multiple steps. As per the ﬁrst step, the person opens his eye and the system reads remotely the changes in pupil size as a result of the response to the ambient illumination. Then, the system starts matching the iris with a database. The second step: the person closes his eye and the system remotely detects the heartbeats signals under the skin of the eyelid. As per the third step, the person opens his eyes again and the system reads the pupil size again and compares the results of the pupil size, and then the system matches again the iris with the above database. For the iris recognition to be validated, all the above checks have to be passed. We have conducted several experiments with our proposed system, based on a brand new dataset comprised of 40 subjects. In addition, we also used public datasets: CASIA-Interval, CASIA-Twin and Ubiris.V1. The achieved results show the quality and viability of our proposal.
Specialized-domain grammars and the architecture of grammars: Possession in Oneida

This paper describes the grammar of possession in Oneida (Northern Iroquoian), a case where domain-specific syntax permeates disparate areas of the grammar (referencing of semantic arguments, noun incorporation, expression of quantity, and negation). In each of these other areas, something unique must be stated, but some of what is special to possession is also shared across two or more of these areas. We describe this interesting mix of general and specific constraints in terms of a metaphor originally applied by Lévi-Strauss to the construction of myths, ‘bricolage’ (tinkering). We suggest the notion of bricolage aptly captures the properties of Oneida words that include a relation of possession. This novel way of conceiving of grammar of specialized domains is an alternative to the view where only general/universal, possibly parametrized, principles are countenanced.

Surface Engineering of the RNA Coliphage Qβ to Display Plasmodium Falciparum Derived Asexual Blood Stage Antigens UB05 and Merozoite Surface Protein 3

Background: Naturally acquired immune responses to Plasmodium falciparum merozoite surface protein 3 (MSP3) and UB05 are implicated in semi immunity in populations living in malaria endemic areas. Thus designing chimeric malaria vaccine candidates involving MSP-3 and UB05 displayed upon the surface of a phage in its native form could potentiate their immunogenicity and antigenicity. In this study, we have engineered both MSP3 and UB05 upon the Qβ and assessed their antigenicity with plasma from children living in a high malaria transmission region of Cameroon. Methods: The surface of the RNA coliphage Qβ was genetically modified to display three Plasmodium falciparum derived immunogens including MSP3, UB05 and a chimera of the two UB05-MSP3. The resultant recombinant phages including QβMSP3, QβUB05 and QβUB05-MSP3 with surface displayed malaria immunogens were produced after transformation of the E. coli strain HB101. Plasma levels of antigen specific IgG antibody were then determined in samples from malaria positive and negative children living in a high malaria transmission region of Cameroon. Results: To improve yield each recombinant phage was scaled up to 1014 pfu/ml using production strategies previously optimized in our group. This was significantly higher (P<0.001) relative to the 108 pfu/ml of the wild type C l i n i c al M icr obio logy: pen cc e s s ISSN: 2327-5073 Clinical Microbiology: Open Access Waffo et al., Clin Microbiol 2018, 7:4 DOI: 10.4172/2327-5073.1000314 Research Article Open Access Clin Microbiol, an open access journal ISSN:2327-5073 Volume 7 • Issue 4 • 1000314 phage when produced routinely. Conformational integrity of the surface displayed antigens was confirmed in ELISA assays by testing for the specific recognition of the N and C-terminal parts of both UB05 and MSP3 using the recombinant QβMSP3, QβUB05 and chimeric QβUB05-MSP3 phages as antigens and the monoclonal antibodies XQ38G73-N, X-Q0KGH2-N, X-Q38G73-C, X-Q0KGH2-C targeting the Nand C-terminals of both UB05 and MSP3 respectively. Antigen specific naturally acquired IgG antibodies in plasma from both malaria negative and positive children living in a high transmission area of Cameroon recognized all three recombinant phages. However, plasma from children less than five years old contained significantly less plasma levels of antigen specific IgG antibodies. Conclusion: Thus, the novel recombinant phages QβMSP3, QβUB05 and QβUB05-MSP3 can be used as a tool for assessing natural or vaccine-induced antibody responses against malaria. The recombinant chimeric QβUB05MSP3 phage is validated as a multivalent antigen for tracking semi immunity to malaria.
A fusion of digital elevation model based on interferometry SAR technique from ascending and descending path in urban area

The height of the earth’s surface can be measured using synthetic aperture radar (SAR) images using interferometry (InSAR). The InSAR method uses phase information to produce the height of the earth’s surface. The accuracy of the DEM produced by InSAR depends on the shadow, the layover area, and the coherence of two SAR data. This paper proposes a technique for combining DEM derived from the InSAR method from ascending and descending paths using high resolution TerraSAR-X/TanDEM-X. Generating DEM was done by the InSAR method which covers the same test area and came from one pair of ascending TanDEM-X images and one descending pair of TerraSAR-X. The combination of the two DEMs from the ascending and descending path has been done by assessing the weighting factors so that the accuracy of the DEM can be increased. The weighting factors are calculated from the height error map, layover and shadow map. The height error map is calculated from the interferometric coherence with geometrical considerations and the layover and shadow map is calculated using TerraSAR-X/TanDEM-X DEM. The images pairs with 33 angles and 37 degrees were used in this study for the InSAR method in urban areas (Jakarta city). The experimental results show a significant reduction in missing pixel counts due to layover, shadow and low coherences after combining.
Graphene quantum dot-sensitized Zn-MOFs for efficient visible-light-driven carbon dioxide reduction

The development of environmentally friendly and highly active photocatalysts for carbon dioxide reduction is one of the most anticipated potential pathways for future carbon dioxide emission treatment. In this work, the rational design and construction of Zn-MOF@GQD heterostructures as efficient and stable photocatalysts were demonstrated. The unique design binds the GQDs into the holes located on the surface of the Zn-Bim-His (MOF) nanoparticles. Compared with GQDs, the obtained optimal composite (Zn-Bim-His-1@GQD) displays dramatically enhanced photoactivity as a catalyst for photocatalytic carbon dioxide conversion at the formation rates of 20.9 and 3.7 μmol h−1 g−1 for CH4 and CO, respectively. The selectivity of methane production by the catalytic reaction is as high as 85%. Moreover, the Zn-Bim-His-1@GQD heterostructures also exhibit high photocatalytic stability and good reusability for the carbon dioxide reduction. The enhanced photocatalytic activity of Zn-Bim-His-1@GQDs can be attributed to the synergistic effect of the intimate contact between Zn-Bim-His-1 and GQDs and the rich active sites on the defective MOF surface. Specifically, the Zn-Bim-His-1@GQDs can effectively promote the spatial separation of the photogenerated electron–hole pairs in the catalytic conversion process. This study is anticipated to provide new opportunities to utilize carbon dot materials and porous MOF crystals in photocatalytic applications.
Barriers to entrepreneurship in public enterprises: boards contributing to inertia

ABSTRACT This article adopts a qualitative comparative causal mapping approach to extend knowledge of the interrelated barriers to public entrepreneurship and the outcomes of such entrepreneurship. The results highlight marked differences between the sales segment and the distribution grid segment of German public enterprises that should prompt a refined perspective on public entrepreneurship. Notably, besides intra-organizational barriers and those interfering from the external environment, results also show that a public enterprise’s supervisory board can hinder its progress. This study thus contributes to recent discussion on governance and entrepreneurship by revealing a feature that could distinguish public from private enterprises.
Sol–gel synthesis and solar photocatalytic activity of Ca-alloyed ZnO nanoparticles elaborated using different precursors

Ca-alloyed ZnO nanoparticles elaborated using different calcium precursors (CaSO4, CaCl2, Ca(NO3)2 and CaCO3) at different [Ca]/[Zn] ratios (0, 1, 5, 10, 15 and 20%) have been prepared by a sol–gel method followed by supercritical drying and annealing at 300 °C. The synthesized samples have been characterized by a number of techniques including Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Diffraction (XRD), Raman Spectroscopy and Electron Paramagnetic Resonance (EPR). SEM and TEM images reveal that the nanoparticles have a quasi-spherical shape with a grain size between 20 and 40 nm. The EDS results on chemical elementary compositions show that the Ca-alloyed ZnO with a CaCO3 precursor and [Ca]/[Zn] ratios of 5 and 10% are quasi-stoichiometric. The XRD results indicate that all the elaborated nanoparticles have a hexagonal wurtzite structure. Using Raman Spectroscopy a supplementary vibrational mode is detected in the case of CaSO4, CaCO3 and Ca(NO3)2 precursors. The intrinsic defect centers and defect number have been studied using EPR. Two intrinsic defects with different g factors are identified by EPR for which the spectral intensities change with calcium precursors. Furthermore, EPR reveals a correlation between the defect number and photocatalytic efficiency. The photocatalytic efficiency of the nanoparticles elaborated with different precursors and compositions has been studied for the solar photocatalytic degradation of pyrimethanil, using a solar simulator. The results show that the nanoparticles of Ca-alloyed ZnO elaborated with a CaCO3 precursor give promising results and enhance the photocatalytic efficiency in the solar field.

An ultra-low-power and high-performance SRAM cell design based on GNRFETs

ABSTRACT In this letter, we propose a new design of an ultra-low-power and high performance six – transistor (6 T) static random access memory (SRAM) cell using graphene nanoribbon field-effect transistors (GNRFETs). HSPICE (Simulation Program with Integrated Circuit Emphasis)-compatible compact GNRFETs model is used to design and validate the different SRAM cells. The proposed cell improves the performance in terms of power consumption, read data stability, and writeability at the low supply voltage. The proposed cell also significantly reduces the leakage power consumption due to excellent control on the gate leakage current. The small bandgap and the high ratio in a GNRFET device show great potential for high-speed nanoelectronics applications. The cell consumes ultra-low power due to its capability to operate below 0.5 V, which makes it suitable for low power applications.
The complete chloroplast genome of a rare species Capparis versicolor Griff. (Rhoeadales: Capparaceae)

Abstract Capparis versicolor Griff. is a rare and threatened medicinal plant in South China. Chloroplast (cp)-derived markers have been widely used to study evolutionary relationships of many species. In this study, the complete cp genome of C. versicolor was assembled based on next-generation sequencing. The whole genome was 155,051 bp in length, consisting of a pair of inverted repeats, large single copy region, and a small single copy region. The cp genome contained 123 genes, including 83 protein-coding genes, 4 rRNA genes, and 36 trRNA genes. The overall GC content of the whole cp genome was 36.38%. A neighbour-joining phylogenetic analysis demonstrated that C. versicolor is clustered together with Pachycladon enysii.
General motivations, basic psychological needs, and problem gambling: applying the framework of Self-Determination Theory

Abstract Background Research into problem gambling has established that the addiction results from a complex array of bio-psycho-social factors. The range of factors, however, has yet to be comprehensively identified. Applications of Self-Determination Theory (SDT) have shown that specific characteristics are associated with problem gambling, including users’ susceptibility to external pressures and a general lack volition in their actions. Additionally, SDT research has found that the frustration of basic psychological needs (i.e. competence, autonomy, and relatedness) is associated with behavioral addictions (e.g. video gaming, exercise dependence). A primary proposal of SDT is that individual characteristics will contribute to maladaptive outcomes through an increased frustration of these needs. This specific proposal has not yet been examined in the context of problem gambling. Purpose The present study assesses an SDT-derived model of problem gambling. Methods An online sample of gamblers from Amazon’s Mechanical Turk (N = 887; 58.9% female, M = 33.871 years; SD = 9.770) completed a battery of assessments. Results Results from a structural equation model largely supported the underlying assumptions of SDT. Specifically, increased susceptibility to external pressures and perceptions of lower control over choice were associated with greater frustration of basic needs, which, in turn, contributed to problem gambling and subsequently to psychological distress. Notably, gamblers were particularly vulnerable to problem gambling if they perceived little to no choice in governing their actions. Conclusions The implications for theory and practice as well as future directions for research are discussed.
Cell-loaded injectable gelatin/alginate/LAPONITE® nanocomposite hydrogel promotes bone healing in a critical-size rat calvarial defect model

Injectable hydrogels have long been gaining attention in the bone tissue engineering field owing to their ability to mix homogeneously with cells and therapeutic agents, minimally invasive administration, and seamless defect filling. Despite the advantages, the use of injectable hydrogels as cell delivery carriers is currently limited by the challenge of mimicking the natural microenvironment of the loaded cells, promoting cell proliferation, and enhancing bone regeneration. To overcome these problems, we aimed to develop an injectable and in situ-forming nanocomposite hydrogel composed of gelatin, alginate, and LAPONITE® to mimic the architecture and composition of the extracellular matrix. The encapsulated rat bone marrow mesenchymal stem cells (rBMSCs) survived in the nanocomposite hydrogel, and the gel promoted cell proliferation in vitro. Systematic in vivo research of the biomimetic hydrogel with or without cells was conducted in a critical-size (8 mm) rat bone defect model. The in vivo results proved that the hydrogel loaded with rBMSCs significantly promoted bone healing in rat calvarial defects, compared to the hydrogel without cells, and that the hydrogel did not provoked side effects on the recipients. Given these advantageous properties, the developed cell-loaded injectable nanocomposite hydrogel can greatly accelerate the bone healing in critical bone defects, thus providing a clinical potential candidate for orthopedic applications.

Introduction: Trunk control disability commonly occurs after stroke. This study investigated the effect of diagonal pattern training in the sitting position to improve trunk control ability and gait performance. Method: 46 stroke patients were enrolled in this study. We used single plane training and diagonal pattern training. Additionally, the subjects were randomly assigned to the experiment group (diagonal pattern training) and the control group (single plane training). Diagonal pattern training was modified with proprioceptive neuromuscular facilitation technique’s chopping and lifting pattern to create 10 movements. Results: the trunk impairment scale score, Berg balance scale score, 10 m walking test result, and gait significantly increased in the experiment group compared to the control group. Conclusions: diagonal pattern training can be regarded as a promising method to improve postural control and increase balance and gait in stroke patients
Production planning and scheduling problem of continuous parallel lines with demand uncertainty and different production capacities

Production planning and scheduling problems are highly interdependent as scheduling provides optimum allocation of resources and planning is an optimum utilization of these allocated resources to serve multiple customers. Researchers have solved production planning and scheduling problems by the sequential method. But, in this case, the solution obtained by the production planning problem may not be feasible for scheduling method. Hence, production planning and scheduling problems must be solved simultaneously. Therefore, in this work, a mathematical model is developed to integrate production planning and scheduling problems. The solution to this integrated planning and scheduling problem is attempted by using a discrete artificial bee colony (DABC) algorithm. To speed up the DABC algorithm, a k-means clustering algorithm is used in the initial population generation phase. This k-means clustering algorithm will help to converge the algorithm in lesser time. A real-life case study of a soap manufacturing industry is presented to demonstrate the effectiveness of the proposed approach. An objective function to minimize overall cost, which comprises the processing cost, material cost, utility cost, and changeover cost, is considered. The results obtained by using DABC algorithm are compared with those obtained by CPLEX software. There is a saving of ₹2 23 324 for weeks 1–4 in overall cost compared with the results obtained by using CPLEX software.
