SELVa: Simulator of evolution with landscape variation

Organisms evolve to increase their fitness, a process that may be described as climbing the fitness landscape. However, the fitness landscape of an individual site, i.e., the vector of fitness values corresponding to different variants at this site, can change with time due to changes in the environment or substitutions at other epistatically interacting sites. We present SELVa, the Simulator of Evolution with Landscape Variation, aimed at modeling the substitution process under a changing single position fitness landscape in a set of evolving lineages forming a phylogeny of arbitrary shape. Written in Java and distributed as an executable jar file, SELVa provides a flexible framework that allows the user to choose from a number of implemented rules governing landscape change.

Phytochemistry and Antioxidant Activity of Molineria latifolia Herb. Extracts

Molineria latifolia is a perennial-monocotyle-donous herb and it is well-known in the treatment of melasma, freckle and black spot in Thai traditional medicine. The purpose of this study was to determine the phytochemicals and antioxidant activity in the aerial parts and the underground parts of M. latifolia by water, ethanolic and ethyl acetate extracts. The phytochemicals were analyzed by HPTLC. The antioxidant activity was measured by using the DPPH radical scavenging activity assay, Ferric reducing antioxidant power assay and Total phenolic content was measured by Folin‑Ciocalteu. The result showed the highest antioxidant activity of the underground parts (RW) were extracted by water at EC50=245.03±6.59 µg/mL(DPPH) and 640.03±0.36 Fe2+/ mg (FRAP). Consequently, the highest phenolics content was found in the water extract of the aerial parts (LW) (191.70±1.64 µg FA/mg). M. latifolia extracts contain a bioactive compound of Tannin, Flavonoids and Steroid . Tannin and Flavonoid were found in both of parts. In the aerial parts were found steroid extracting by ethyl acetate and ethanolic, as the underground parts were seen steroid extracting by water. It was found that M. latifolia has high bioactive compounds and moderate antioxidant activity. These results for the cosmetic product development in the future.
3-D Modeling of Multicrystalline Silicon Materials and Solar Cells

We present a method to model large-area multicrystalline materials using Quokka3, based on artificially generated lifetime images created by combining injection-dependent intragrain lifetimes and defect recombination velocity maps extracted from photoluminescence-based lifetime images. It is found that simulations based only on measured lifetime images underestimate the detrimental impacts of crystal defects and, hence, overestimate the overall cell performance of multicrystalline silicon solar cells. As demonstration, we applied Quokka3 simulations to resolve various bulk recombination losses in industrial multicrystalline silicon solar cells, quantify the effects of phosphorus diffusion and hydrogenation on the final cell performance, and evaluate the detrimental impact of crystal defects on individual cell parameters. Through numerical simulations, this paper has also demonstrated the potential errors of using a single average value to predict the cell performance of inhomogeneous multicrystalline silicon materials. It is observed that the commonly used harmonic mean can provide a good indication for Voc, but is less effective for predicting Jsc, and is almost entirely ineffective for predicting the fill factor.
Understanding Provider Attitudes Regarding Father Involvement in Early Intervention

The interest in fathers as active parents has increased dramatically over the past 30 years among researchers and the popular press with considerable attention given to direct child-rearing activities; however, mothers continue to be the most likely participants in early intervention (EI) services. Using thematic analysis, we explored providers’ perceptions (N = 511) of father involvement in EI regarding (a) the impact of increased father involvement, (b) how father involvement could be increased, and (c) the role of culture in father involvement. Providers believed more involvement was better and identified several ways in which fathers made a difference. Some providers believed it was not in their hands to increase involvement; however, other providers identified systems-level and direct approaches. Providers preponderantly reported culture as a barrier to involvement but there were notable exceptions. We recommend providers receive professional development to support family-centered philosophies and practices that are inclusive of fathers.
Venue2Vec: An Efficient Embedding Model for Fine-Grained User Location Prediction in Geo-Social Networks

Geo-Social Networks (GSN) significantly improve location-aware capability of services by offering geo-located content based on the huge volumes of data generated in the GSN. The problem of user location prediction based on user-generated data in GSN has been extensively studied. However, existing studies are either concerning predicting users’ next check-in location or predicting their future check-in location at a given time with coarse granularity. A unified model that can predict both scenarios with fine granularity is quite rare. Also, due to the heterogeneity of multiple factors associated with both locations and users, how to efficiently incorporate these information still remains challenging. Inspired by the recent success of word embedding in natural language processing, in this paper, we propose a novel embedding model called Venue2Vec which automatically incorporates temporal-spatial context, semantic information, and sequential relations for fine-grained user location prediction. Locations of the same type, and those that are geographically close or often visited successively by users will be situated closer within the embedding space. Based on our proposed Venue2Vec model, we design techniques that allow for predicting a user’s next check-in location, and also their future check-in location at a given time. We conduct experiments on three real-world GSN datasets to verify the performance of the proposed model. Experimental results on both tasks show that Venue2Vec model outperforms several state-of-the-art models on various evaluation metrics. Furthermore, we show how the Venue2Vec model can be more time-efficient due to being parallelizable.
Unsupervised Neural Network for Modulation Format Discrimination and Identification

We propose a new method to discriminate and identify the modulation format of signals based on an unsupervised neural network named convolutional Gaussian–Bernoulli restricted Boltzmann machine (CGBRBM). Tests are performed to demonstrate how the proposed method works and to evaluate the discrimination/identification accuracy for different input combinations. Signals of five modulation formats are used to test the CGBRBM-based algorithm including QPSK, 8QAM, 16QAM, 32QAM, and 64QAM. The results indicate the performance of the proposed method when dealing with various application scenarios and reveal the relation between discrimination accuracy and identification accuracy.
Advanced Microgrid Energy Management System for Future Sustainable and Resilient Power Grid

Microgrid technology has found applications in various areas including institutional campuses, military bases, and remote islands. Many research efforts focus on the development of the microgrid steady-state energy management system (EMS) that can provide the day-ahead schedule or the multi-interval economic dispatch (ED) for distributed energy resources (DERs). This study advances the state-of-the-art microgrid EMS technique by developing a novel EMS approach to achieve a flexible time frame (FTF) DER schedule combined with a single time interval optimal power flow (OPF)-based ED. The FTF DER schedule enables the microgrid to fully utilize the latest updated renewable and load forecasts, and the OPF-based ED integrates realistic microgrid operating constraints in the real-time control. In addition, a mode switching control function is included to re-dispatch DERs in the microgrid for the planned microgrid switching from grid-connected mode to island mode. The feasibility and effectiveness of the proposed microgrid EMS technology are tested and demonstrated using modified IEEE 34-node and 123-node systems.
Radiation Use Efficiency of Forage Resources: A Meta‐Analysis

Forage production is increasingly monitored through models based on remote sensing. Radiation use efficiency (RUE) is a key input to these models. However, no study has synthesized the published values of RUE of forage resources. Our objective was to quantitatively synthesize through a meta-analysis the variation of RUE of forage resources and its main controls. We gathered 496 RUE values and assessed their variation according to genotype, resource availability and phenological stage. Mean RUE was 1.93 ± 1.2 g of dry matter (DM) per megajoule of intercepted photosynthetically active radiation (IPAR) (±SD). The RUE was most responsive to genotype and to direct and indirect manipulations of resource availability. Within genotype treatments, mean effect size of C₄ species identity, cultivar identity and C₃ species identity was 61, 58, and 42%, respectively. Within resource availability treatments, mean effect size was 43% for N fertilization, 40% for shading and inter-annual environmental variation and 23% for irrigation and defoliation frequency. For the phenology treatment, mean effect size of reproductive vs. vegetative stage did not differ from zero. This large variability implies a challenge to select RUE values as input to estimate productivity through plant-growth models, such as those based on remote sensing, but also highlight the margin for increasing RUE through breeding and management practices.
4 Powering of Graphs

The above theorem implies that for an (N, d, λ)-expander, the number of neighbors of S is at least constant fraction of |S| (for |S| ≤ N/2), where the constant ε depends only on λ and is independent of the size of the graph. This implies that the diameter of G is at most O(logN) because of the following argument: Consider any two vertices s and t in G. The number of vertices within distance r of s (or t) grows exponentially in r ((1 + ε) to be precise), and hence there are more than N/2 vertices within a O(logN) distance of s (or t). Thus, the distance between any s and t is also O(logN).
Morphodynamic evolution in a meandering reach of the Middle Yangtze River under upstream and downstream controls

Morphodynamic evolution in an alluvial river is usually controlled by various boundary conditions. During the past nearly 50 years, remarkable morphodynamic evolution occurred in the Jianli reach of the Middle Yangtze River owing to the combined effects of an artificial cutoff, the upstream operation of the Three Gorges Project (TGP), and the downstream confluence of the Dongting Lake. To better understand the characteristics of morphodynamic changes in the whole study reach, variations in thalweg shifting and bankfull channel geometry were quantified using a reach-averaged approach, and the effects of upstream and downstream controls were investigated on channel geometry adjustments. Calculated results indicate that: (i) events of an artificial cutoff and high flows caused the average rate of reach-scale thalweg migration to be greater than 35 m/yr, but there was a 22% reduction in the mean migration rate after the TGP operation; (ii) channel geometry adjusted mostly in the aspect of bankfull depth under various river regulation engineering, with the reach-scale bankfull depth increasing by 0.95 m from 2002 to 2016; (iii) the reach-scale bankfull dimensions are closely associated with these accumulated effects of both the altered flow-sediment regime because of upstream dam construction, and the local base-level variation owing to the downstream confluence of the Dongting Lake. Furthermore, these bankfull variables were expressed by power functions of two key parameters, covering the previous five-year average fluvial erosion intensity during flood seasons at Jianli (upstream control), and the corresponding water level difference between Jianli and Lianhuatang (downstream control). The proposed relations were calibrated by the observed data in 2002–2014, and were further verified by measurements in 2015–2016. The proposed methodology can also be applicable to estimate channel geometry adjustments of other similar alluvial rivers controlled by both upstream and downstream boundary conditions.

The Moderating Effect of Job Aid on the Relationship between Work Environment and Employees’ Productivity in Oil and Gas Development Company Limited (OGDCL) of Pakistan

Employees are central in the process of achieving organizational mission and vision through innovative products and services to outshine their competitors. However, employees need a work environment that permits them to work freely without problems. Prior literature indicates that work environment positively or negatively affects employees’ productivity at workplace. Much research has been performed to investigate the effect of work environment and its various components on the employees’ performance and productivity in various settings. However, Pakistani oil and gas industry especially OGDCL remained unexplored. Moreover, none of the studies have investigated the moderating effect of job aid on the relationship between work environment and employees’ productivity. This study examined the moderating effect of job aid on the relationship between work environment and employees’ productivity in OGDCL. A conceptual model was developed and tested using sample data of 70 employees from OGDCL and applying PLS-SEM. The results indicated that job aid positively moderated the relationships between supervisor support and employees’ productivity, adequate workload and employees’ productivity, physical work environment and employees’ productivity. However, the relationships between incentives and recognition plans and employees’ productivity and good relations with co-workers and employees’ productivity were not moderated by job aid. The results provide important implications for academicians and practitioners. From academicians’ point of view, the study enhances the scope of work environment factors influencing the employees’ productivity especially in oil & gas companies. From practitioners’ point of view, the results of the study could be used by the authorities at OGDCL and similar environment to accept the important variables that are crucial for the work environment and lead towards employees’ productivity in this setting. Such an acceptance would help not only to improve work environment but also employees’ productivity.
Discrete consumers, small scale resource heterogeneity, and population stability

We present a consumer-resource model in which individual consumers subsist on a continuum of resource distributed over a very large number of small ‘‘bite-sized’’ patches, each patch being sufficiently small that all its resource is eaten whenever a consumer visits. This form of consumer‐resource interaction forces a heterogeneous distribution of resource among the patches, and may dampen out the large amplitude, consumer-resource cycles that are predicted by traditional models of well-mixed, spatially homogeneous systems. The resource equilibrium does not increase with enrichment, a prediction that distinguishes this model from models that invoke direct or indirect consumer density dependence as a stabilizing mechanism.
Housing Experiences of Pakistani Immigrant Labors in Malaysia

This research considered housing experiences of Pakistani labors in Malaysia that is a main aspect in successful integration. The main focus was on housing rental market, the housing quality and the unfavourable health influences by insufficient housing. Little study was conducted on the housing experiences of Pakistani labor in Malaysia. A qualitative research with inductive approach was applied.Pakistani immigrant labors from Klang Valley were informants in this research. Data were gathered through in-depth interviews. The results indicated that immigrants have their housing more tough than predicted, mostly due to high costs. Immigrants were split about the quality of rental houses. Those who were satisfied could afford the house in private housing market. However, those immigrants who were not satisfied could not afford more suitable housing. They have issues of over-crowding, pest infiltration, damp properties. This research recommended that services of housing and settlement should deliver more direct support to new immigrants. Immigration settlement policies must ensure the presence of more affordable housing; employment opportunities that offer a satisfactory salary and quality programs and services to integrate new immigrants into the public.
PRELIMINARY EVALUATION OF DELONIX REGIA SEED GUM AS A SUSPENDING AGENT IN A LIQUID ORAL DOSAGE FORM

The study focused on the extraction and utilization of Delonix regia seed gum as a suspending agent in amoxicillin dry granules for reconstitution. The seeds were dehauled, defatted with diethyl ether and the gum extracted from its aqueous dispersion by antisolvent precipitation method. Delonix regia gum (DRG), sodium carboxymethyl cellulose (CMC) and hydroxylpropylmethyl cellulose at 0.50, 0.75 and 1.00% (with or without NaCl at 0.02% or 0.04%) were separately used to formulate amoxicillin granules. The granules were reconstituted and characterized using standard protocols for suspension dosage forms. Results revealed that at similar concentrations, products viscosities were: CMC>HPMC>DRG; and pourability: DRG>HPMC>CMC. At 1.00%, DRG gave the best product and flocculation with NaCl was better at 0.02%. The order of degree of flocculation at 1.00% suspendant and 0.02% NaCl was DRG>HPMC>CMC, while at 0.04% NaCl, it was CMC>HPMC>DRG. Ease of redispersion for DRG products was significantly better (p<0.05) than those of CMC, HPMC and two popular commercial products in Nigeria. Particles shapes and interaction with the excipients as revealed by photomicrographs illuminated some of the observed properties of the products, in that the ones whose particles were planar or acicular shaped had significantly higher (p<0.05) degree of flocculation than products containing mostly circular particles. In conclusion, the qualities of products formulated with DRG compared very well and for redispersibility is significantly better (p<0.05) than products formulated with standard suspending agents and the two popular commercial products in Nigeria markets.
Transmission and scattering of acoustic energy in turbulent flows

Submitted for the DFD17 Meeting of The American Physical Society Transmission and scattering of acoustic energy in turbulent flows DATTA GAITONDE, S UNNIKRISHNAN, Ohio State Univ Columbus — Sound scattering and transmission in turbulent jets are explored through a control volume analysis of a Large-Eddy Simulation. The fluctuating momentum flux across any control surface is first split into its rotational turbulent ((ρu)H) and the irrotationalisentropic acoustic ((ρu)A) components using momentum potential theory (MPT). The former has low spatio-temporal coherence, while the latter exhibits a persistent wavepacket form. The energy variable, specifically, total fluctuating enthalpy, is also split into its turbulent and acoustic modes, H ′ H and H ′ A respectively. Scattering of acoustic energy is then (ρu)HH ′ A, and transmission is (ρu) ′ AH ′ A. This facilitates a quantitative comparison of scattering versus transmission in the presence of acoustic energy sources, also obtained from MPT, in any turbulent scenario. The wavepacket converts stochastic sound sources into coherent sound radiation. Turbulent eddies are not only sources of sound, but also play a strong role in scattering, particularly near the lipline. The net acoustic flux from the jet is the transport of H ′ A by the wavepacket, whose axisymmetric and higher azimuthal modes contribute to downstream and sideline radiation respectively.
