Effects of Artificial Light Treatments on Growth, Mineral Composition, Physiology, and Pigment Concentration in Dieffenbachia maculata “Compacta” Plants

Specific wavebands may allow precise control of plant growth. However, light sources must be carefully evaluated before the large-scale use of supplemental light sources can be implemented. Dieffenbachia maculata “Compacta” plants were grown for 8 weeks in pots in a growth chamber under tightly controlled temperature and humidity in order to assess the effects of supplemental light. Three treatments were applied: (i) using 18-W fluorescent bulbs (T1), (ii) using the same bulbs with supplemental light emitting diodes (LEDs) (Pure Blue and Pure Red Mix-Light-Emitting Diodes (BR-LEDs)) (T2), and (iii) using high-efficiency TL5 fluorescents (T3). Plant biomass, mineral composition, and physiological and photosynthetic parameters were assessed under each light treatment. Total plant dry weight was highest in plants grown under treatments T1 and T3. Other differences were observed between different light treatments, including variation in biomass partitioning as well as N and K concentrations in roots, stems, and leaves. Further, proline and indole 3-acetic acid (IAA) levels were higher in plants grown under the T1 treatment, whereas total soluble sugars and starch were higher in plants grown under treatment T3. Plants grown under treatment T1 had the lowest chlorophyll concentrations. No differences were observed in organ water content and P concentration. T2 was not the best treatment, as expected. The model proposed a linear regression between integrated use of spectral energy (IUSE) and total dry weight (TDW), which showed a good relationship with an R2 value of 0.83. Therefore, we recommend this methodology to discern the effects of the different spectral qualities on plant biomass.
A perlecan-inducing compound significantly inhibits smooth muscle cell function and in-stent intimal hyperplasia: novel insights into the diverse biological effects of perlecan.

AIMS Perlecan is the major heparan sulfate proteoglycan in the arterial wall. Previous studies have suggested that perlecan is a potent inhibitor of smooth muscle cell (SMC) activity. Therefore, perlecan overexpression may serve as a therapeutic modality to prevent in-stent restenosis (ISR). We have investigated a novel compound (RUS3108), identified in a SMC based screen to induce perlecan synthesis in SMC. The aims of this study were to assess the in vitro effects of RUS3108 and the effects of RUS3108-eluting stents in preventing ISR. METHODS AND RESULTS Rabbit aortic SMC and bovine aortic endothelial cells (EC) were used in this study. Immunohistochemistry showed that RUS3108-treated SMC over-expressed perlecan indicating the drug effects. Furthermore, RUS3108 induced a SMC differentiated phenotype by SMembryonic staining. RUS3108 (1 microM) inhibited 3H-thymidine incorporation by >50%, which was completely reversed by a perlecan antibody. RUS3108 also inhibited SMC migration (Boyden chamber) and MMP-9 activity. In contrast, RUS3108 (100nM) modestly stimulated EC 3H-thymidine incorporation by 22% (p<0.02). In vivo, a total of 30 stents were deployed in rabbit iliac arteries as follows: 1) bare metal stents (n=10), 2) polymer onlycoated stents (n=10), and 3) polymer-coated stents containing RUS3108 (n=10). Rabbits were sacrificed at four weeks and stented segments were subjected to morphometric analysis. Intimal cross sectional area was significantly lower in the RUS3108-eluting stent group (0.31+ or -0.27 mm(2) versus 1.0 + or - 0.31 and 1.25 + or - 0.51 in the bare metal stents and polymer only coated stents groups, respectively, p<0.0001). CONCLUSIONS RUS3108 is a novel perlecan-inducing compound, which is a potent inhibitor of SMC activity and a modest stimulator of EC proliferation. RUS3108-eluting stents may serve as an excellent modality for the prevention of ISR.
Polymer-free cerivastatin-eluting stent shows superior neointimal inhibition with preserved vasomotor function compared to polymer-based paclitaxel-eluting stent in rabbit iliac arteries.

AIMS The present study was designed to evaluate vasomotor function and vascular biological responses following a novel non-polymeric cerivastatin-eluting stent (CES) versus polymer-based paclitaxel-eluting stent (PES) in a rabbit iliac artery model. Optimisation of DES components and non-polymeric stents may contribute to vascular healing and beneficial to vasomotor function. METHODS AND RESULTS In vitro human aortic and coronary smooth muscle cells (hASMC & hCSMC), as well as endothelial cells (hAEC & hCEC) were cultured. IC50 curves were determined for cerivastatin (CER). In vivo PES (n=6) and CES (n=12) stents were implanted in nine rabbits. Vasomotor function was investigated at 28 days by acetylcholine (ACh) followed by histopathological and histomorphometric analyses. CER was cytotoxic to hASMC and hCSMC (IC50s of 10-6 M and 10-5 M, respectively), although such cytotoxic effects were not observed for hAEC and hCEC at maximal study dose. PES-associated vasodilation response to endothelial-dependent ACh was significantly suppressed at both proximal and distal adjacent arterial segments, as compared to CES. Furthermore, microscopically, neointimal inhibition quantified by the neointimal cross-sectional area (IA) was superior with CES (0.60 + or - 0.27 mm(2)) compared to PES (1.35 + or - 0.16 mm(2); P <0.05). Medial area was smaller for PES (0.3 + or - 0.04 mm(2)) than CES (0.5 + or - 0.03 mm(2), p <0.001). Additionally, significant inflammation and fibrin deposition was clearly evidenced in PES compared to CES (p <0.05). CONCLUSIONS CER elicits a differential effect on hSMC compared to hEC in vitro. In contrast to PES, a novel bioabsorbable sol-gel coated CES demonstrated effective neointimal inhibition with less vessel wall toxicity accompanied by preservation of vasomotor function in the rabbit iliac model.
Between-centre reproducibility of volumetric intravascular ultrasound radiofrequency-based analyses in mild-to-moderate coronary atherosclerosis: an international multicentre study.

Aims: To assess for the first time in a multicentre design the between-centre reproducibility of volumetric virtual histology intravascular ultrasound (VH-IVUS) measurements with a semi-automated, computer-assisted contour detection system in mild-to-moderately diseased coronary segments. Methods and results: Analysts of four European IVUS centres performed independent IVUS analyses (in total 7,188 cross-sectional analyses) and obtained volumetric data to evaluate the reproducibility of volumetric VH-IVUS measurements in 36 coronary segments (length 20.0±0.4 mm) from patients with stable angina. Geometric and compositional VH-IVUS measurements were highly correlated for the different comparisons. Overall intraclass correlation for vessel, lumen, plaque volume and plaque burden were 0.98, 0.92 0.95, and 0.86, respectively; for fibrous, fibro-lipidic, necrotic core and calcified volumes overall intraclass correlations were 0.95, 0.93, 0.99, and 1.00, respectively. There were significant but small differences for vessel, lumen, fibrous and calcified volumes, and there was no significant difference for plaque volume. Of the plaque components necrotic core and calcified volume showed on average the highest reproducibility. Conclusions: These findings underline the necessity to centrally analyse IVUS data obtained in multicentre studies addressing mild-to-moderately diseased coronary arteries. In addition, pooling VH-IVUS data from different studies, analysed at different centres, may be problematical.
The Structural Colors of Photonic Glasses

The color of materials usually originates from a combination of wavelength‐dependent absorption and scattering. Controlling the color without the use of absorbing dyes is of practical interest, not only because of undesired bleaching properties of dyes but also regarding minimization of environmental and health issues. Color control without dyes can be achieved by tuning the material's scattering properties in controlling size and spatial arrangement of scatterers. Herein, calibrated photonic glasses (PGs), which are isotropic materials made by random aggregation of nonabsorbing, monodisperse colloidal polystyrene spheres, are used to generate a wide spectral range of purely structural, angular‐independent colors. Experimental reflectance spectra for different sized spheres compare well with a recent theoretical model, which establishes the latter as a tool for color mapping in PGs. It allows to determine the range of visible colors accessible in PGs as function of size, packing fraction, and refractive index of scatterers. It also predicts color saturation on top of the white reflectance as function of the sample's optical thickness. Blue, green, and red are obtained even with low index, while saturated green, cyan, yellow, and magenta can be reached in higher index PGs over several orders of magnitude of sample thickness.
Delegating computation: interactive proofs for muggles

In this work we study interactive proofs for tractable languages. The (honest) prover should be efficient and run in polynomial time, or in other words a "muggle". The verifier should be super-efficient and run in nearly-linear time. These proof systems can be used for delegating computation: a server can run a computation for a client and interactively prove the correctness of the result. The client can verify the result's correctness in nearly-linear time (instead of running the entire computation itself). Previously, related questions were considered in the Holographic Proof setting by Babai, Fortnow, Levin and Szegedy, in the argument setting under computational assumptions by Kilian, and in the random oracle model by Micali. Our focus, however, is on the original interactive proof model where no assumptions are made on the computational power or adaptiveness of dishonest provers. Our main technical theorem gives a public coin interactive proof for any language computable by a log-space uniform boolean circuit with depth d and input length n. The verifier runs in time (n+d) • polylog(n) and space O(log(n)), the communication complexity is d • polylog(n), and the prover runs in time poly(n). In particular, for languages computable by log-space uniform NC (circuits of polylog(n) depth), the prover is efficient, the verifier runs in time n • polylog(n) and space O(log(n)), and the communication complexity is polylog(n). Using this theorem we make progress on several questions: We show how to construct short (polylog size) computationally sound non-interactive certificates of correctness for any log-space uniform NC computation, in the public-key model. The certificates can be verified in quasi-linear time and are for a designated verifier: each certificate is tailored to the verifier's public key. This result uses a recent transformation of Kalai and Raz from public-coin interactive proofs to one-round arguments. The soundness of the certificates is based on the existence of a PIR scheme with polylog communication. Interactive proofs with public-coin, log-space, poly-time verifiers for all of P. This settles an open question regarding the expressive power of proof systems with such verifiers. Zero-knowledge interactive proofs with communication complexity that is quasi-linear in the witness, length for any NP language verifiable in NC, based on the existence of one-way functions. Probabilistically checkable arguments (a model due to Kalai and Raz) of size polynomial in the witness length (rather than the instance length) for any NP language verifiable in NC, under computational assumptions.
Microbiologically Influenced Corrosion of Carbon Steel Beneath a Deposit in CO2-Saturated Formation Water Containing Desulfotomaculum nigrificans

The corrosion mechanism of carbon steel under deposit in the presence of sulfate reducing bacterium (SRB) Desulfotomaculum nigrificans was studied using surface analysis, weight loss and electrochemical measurements. Results showed that both the general corrosion and localized corrosion were considerably promoted by SRB under deposit. The corrosion rate of steel in the presence of SRB was approximately 6 times of that for the control according to the weight loss measurements. The maximum corrosion pit depth in the presence of SRB was approximately 7.7 times of that of the control. Both the anodic and cathodic reactions were significantly accelerated by SRB. A galvanic effect in the presence of SRB due to the heterogeneous biofilm led to serious localized corrosion.
Research Regarding Heritability and Repeatability Coefficients of some Milk Production Traits from Farms in Moldavian Region

Aim of this study was estimation of two genetic parameters: heritability and repeatability, for five milk production traits. Data used in current paper consisted from phenotypic information from 998 cows with 1897 yield records. The traits which were considered for 305 days of lactation included milk, fat ant protein yields and percentages of milk fat and protein. Data were statistically analyzed through the S.A. V.C. (Statistical Analyze of Variance and Covariance) software. The estimated heritabilities for studied traits were 0.24 to 0.38 for milk yield (MY), 0.27 to 0.41 for fat yield (FY), 0.61 to 0.87 for percentage of fat (F%), 0.25 to 0.39 for protein yield (PY) and 0.59 to 0.78 for percentage of protein (P%). Repeatability estimates for studied traits ranged from 0.27 to 0.34 for MY, from 0.30 to 0.41 for FY, from 0.67 to 0.86 for F%, from 0.28 to 0.39 for PY and from 0.62 to 0.77 for P%. Results from this paper are in line with values reported from other authors. Also, Fisher results indicate significant differences between studied farms.

The comments of interviewees on the future of online gaming in Vietnam are also analyzed in depth. The results retrieved from the interviews provide readers with the information regarding the development of the online gaming industry in Vietnam, which also entails a number of legal and economic challenges- those that arise in the specific post-war historical and political context.
A 3–6-GHz Highly Linear I-Channel Receiver With Over +3.0-dBm In-Band P1dB and 200-MHz Baseband Bandwidth Suitable for 5G Wireless and Cognitive Radio Applications

A highly linear I-channel receiver prototype is presented for a 3–6-GHz broadband radio system with a 200-MHz baseband bandwidth and verified to operate under congested spectrum environments. A direct conversion receiver developed from this prototype is suitable for a cognitive radio, a fifth-generation (5G) receiver, and other wireless systems with a total (in-band signal plus blocker) power of above −6.0 dBm. The broadband receiver consists of a low-noise transconductance amplifier (LNTA), a passive mixer, a wideband transimpedance amplifier, and a power-efficient minimally invasive baseband filter. The LNTA with high linearity employs a cross-coupled structure and resistive degeneration to achieve low noise and high linearity simultaneously. The common-gate-based LNTA achieves 2.3-dB noise figure in simulation. Fabricated in a mainstream 40-nm CMOS technology, the worst case measured system noise figure is under 5.8 dB at 3-MHz baseband frequency, and the conversion gain is larger than 12.8 dB with passband variations under 2 dB from 1- up to 200-MHz signal bandwidth. Over 3–6 GHz, the receiver’s in-band input third-order intercept point (IIP3) and input P1db are higher than 15.1 and 3.0 dBm, respectively, whereas the power consumption varies from 64.1 to 69.6 mW.
Social media for outbound leisure travel: a framework based on technology acceptance model (TAM)

Purpose The purpose of this paper is to explore the applicability of technology acceptance model (TAM) to explain the widespread acceptance and usage of social media (SM) for travel purposes by Indian outbound leisure travellers during their travel cycle. Design/methodology/approach The study has adopted a qualitative approach involving in-depth interviews of 30 respondents, who had taken at least one international vacation in the last 12 months. Content analysis was used to arrive at the conclusion. Findings Findings of the study are used to develop a conceptual model which upholds the validity of the TAM with perceived usefulness (PU) and perceived ease of use (PEU) as determinants of SM usage. The model has been extended to include perceived trust (PT) and social capital (SC) as important constructs to explain the travellers’ use of SM. Disposition readiness (DR) of the user towards SM was found to have an effect on all the four constructs. Originality/value Theoretically, this study suggests a modification to the existing TAM, which shows a unidirectional effect of PU and PEU on attitude. This study suggests that the effect would be bi-directional where the attitude (DR) of the traveller towards SM usage will affect PU and PEU. Furthermore, this study extends the TAM to include PT and SC as important constructs to explain SM usage by travellers. This study provides valuable insights into the hospitality and tourism sector which might help in further segmentation of travellers leading to more customised service offerings.
EMPIRICAL ASSESSMENT OF CALLOUS-UNEMOTIONAL TRAITS IN PRESCHOOL: A COMPARISON OF CONFIRMATORY FACTOR ANALYSIS AND NETWORK ANALYSIS

OF THESIS EMPIRICAL ASSESSMENT OF CALLOUS-UNEMOTIONAL TRAITS IN PRESCHOOL: A COMPARISON OF CONFIRMATORY FACTOR ANALYSIS AND NETWORK ANALYSIS Callous – unemotional (CU) traits are a key factor in understanding the persistence and severity of conduct problems. The factor structure of CU traits has been primarily examined through confirmatory factor analysis (CFA) in childhood and adolescent samples, yet little research has examined the structure of CU traits in preschool. Further, current CFA models have yielded poor – to – marginally acceptable fit, suggesting the need for a more nuanced approach in understanding the structure of CU traits in early childhood using an interitem approach (i.e., network analysis). Within a sample of 109 preschool children (M age = 4.77, SD = 1.10), CFA results supported a two – factor structure of the ICU, comprised of “callous” and “uncaring” factors. Results of the network analysis identified seems cold and uncaring as most central to the CU network. Results from the CFA demonstrated that CU traits can be assessed in preschool children using 12 of the original 24 items from the ICU, which is consistent with a small portion of research. Further, results of the network analysis suggested that seems cold and uncaring may be useful in screening for psychopathic traits in preschool children. Clinical implications, including ICU measure refinement, are explored.
How the Human Mind Affects Its Related Brain? A Mechanism for this Influence, Using an Extended Bohmian QM in Avicenna’s Monotheistic Perspective

In quantum approaches to consciousness, the authors try to propose a model and mechanism for the mind-brain interaction using modern physics and some quantum concepts which do not exist in the classical physics. The independent effect of mind on the brain has been one of the challenging issues in the history of science and philosophy. In some recent mind-brain interaction models, the direct influence of mind on matter is either not accepted (as in Stapp’s model) or not clear, and there have not been any clear mechanism for it (as in Penrose-Hameroff’s model or in Eccles’s model). In this manuscript we propose a model and mechanism for mind’s effect on the matter using an extended Bohmian quantum mechanics and Avicenna’s ideas. We show that mind and mental states can affect brain’s activity without any violation of physical laws. This is a mathematical and descriptive model which shows the possibility of providing a causal model for mind’s effect on matter. It is shown that this model guarantees the realistic philosophical constraints and respects the laws of nature. In addition, it is shown that it is in agreement with the Libet style experimental results and parapsychological data. To propose this model, we obtained a modified (non-unitary) Schrödinger equation via second quantization method which affects the particle through a modified quantum potential and a new term in the continuity equation. At the second quantized level, which is equivalent to quantum field theory level (QFT), we can use the path integral formalism of Feynman. We show that there are three methods to extend Bohmian QM via path integral formalism, which has different interpretations. By numerical simulation of trajectories in the two-slits experiment, we show their differences and choose one of these methods for our mind-brain model which can be the basis for explaining some phenomena which are not possible to explain in the standard Bohmian QM.
Chemical Bonding and Physical Properties in Quasicrystals and Their Related Approximant Phases: Known Facts and Current Perspectives

Quasicrystals are a class of ordered solids made of typical metallic atoms but they do not exhibit the physical properties that usually signal the presence of metallic bonding, and their electrical and thermal transport properties resemble a more semiconductor-like than metallic character. In this paper I first review a number of experimental results and numerical simulations suggesting that the origin of the unusual properties of these compounds can be traced back to two main features. For one thing, we have the formation of covalent bonds among certain atoms grouped into clusters at a local scale. Thus, the nature of chemical bonding among certain constituent atoms should play a significant role in the onset of non-metallic physical properties of quasicrystals bearing transition-metal elements. On the other hand, the self-similar symmetry of the underlying structure gives rise to the presence of an extended chemical bonding network due to a hierarchical nesting of clusters. This novel structural design leads to the existence of quite diverse wave functions, whose transmission characteristics range from extended to almost localized ones. Finally, the potential of quasicrystals as thermoelectric materials is discussed on the basis of their specific transport properties.
Expectation-maximization Gaussian-mixture approximate message passing

When recovering a sparse signal from noisy compressive linear measurements, the distribution of the signal's non-zero coefficients can have a profound affect on recovery mean-squared error (MSE). If this distribution was apriori known, one could use efficient approximate message passing (AMP) techniques for nearly minimum MSE (MMSE) recovery. In practice, though, the distribution is unknown, motivating the use of robust algorithms like Lasso-which is nearly minimax optimal-at the cost of significantly larger MSE for non-least-favorable distributions. As an alternative, we propose an empirical-Bayesian technique that simultaneously learns the signal distribution while MMSE-recovering the signal-according to the learned distribution-using AMP. In particular, we model the non-zero distribution as a Gaussian mixture, and learn its parameters through expectation maximization, using AMP to implement the expectation step. Numerical experiments confirm the state-of-the-art performance of our approach on a range of signal classes.
