Knowledge Graph Embeddings for Recommender Systems

“Less is more” is the motto that the architect Ludwig Mies van der Rohe invented to describe the minimalist aesthetic in architecture. In the digital age, though, abundance is king: it is estimated that 90% of all the world’s data has been created in the past two years. This abundance of options to choose from within just one-click should make us happier and more satisfied with our decisions, allowing us to find what is just right for our needs. In fact, psychological studies show that humans are quite bad at choosing among many different options (“The Paradox of choice” [1]). Recommender Systems are software tools that create a personalized filter that help users in reducing the number of available options, pre-filtering a subset of items that are deemed relevant, and thus helping in addressing the paradox of choice. Knowledge graphs are an ideal data structure for recommender systems, as they allow to easily represent user-item interactions, and item and user properties as typed edges connecting pairs of entities. Recommender systems based on knowledge graphs have shown to generate high quality recommendations that are also easier to interpret and explain [2–4]. However, engineering features for recommender systems from a knowledge graph is a complex, time-consuming and domain-dependent endeavor.
Species interactions in pure and mixed-species stands of silver fir and European beech in Mediterranean mountains

Soraya Versace , Vittorio Garfì , Michele Dalponte , Mirko Di Febbraro , Lorenzo Frizzera , Damiano Gianelle , Roberto Tognetti (3-4) Interactions between tree species determine the dynamics of forest communities. Spatial and temporal changes in resource availability, variation in species composition and spatial distribution of trees may alter competitive interactions between species and, therefore, affect tree growth and forest productivity. In this study, we analyzed the intra and inter-specific interactions between European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) in southern Italy (Molise and Calabria regions), and how these interactions affect basal area increments in mixed-species and pure stands. Results showed that intraspecific interactions have a negative effect on the basal area increment, both in pure and mixed-species stands of Molise and Calabria. Basal area increment was higher influenced by intra-specific interactions in pure stands than in mixed-species stands. Silver fir in Molise showed higher basal area increment in mixed-species stand, probably in relation with stand structure and space occupation that resulted in less competition between individual trees. European beech showed high values of intra-specific interactions in pure stands, likely related to the low self-tolerance of this species and to the spatial arrangement of trees, due to canopy closure. The absence of inter-specific interactions in mixed-species stands could be explained by the sub-dominant position of European beech, which may have limited the benefit derived from niche separation and complementarity for silver fir.
Physical properties of Hurda (Tender Sorghum)

Research were conducted to evaluate some moisture dependent engineering properties of hurda (tender sorghum) PKV Ahwini in the moisture range of 62.28 to 70.13 % (d. b.). It was aimed at investigating engineering properties of hurda (tender sorghum) viz., moisture content (db), bulk density, porosity, true density, sphericity, geometric mean diameter, angle of repose, coefficient of friction and thousand kernel weight. Results of the investigations showed that length, breadth and thickness were increased linearly with increase in moisture content. The grain size increased linearly with increase in moisture content from 62.28 to 70.13 % % (w.b.). The average values obtained for the size were 3.55 mm, 3.78 mm and 4.03 mm, The sphericity ranged from 0.838-0.869 at moisture content 62.28 % to 70.13 % (w.b.) respectively. Thousand grain mass was increased from 20.41 to 21.14 g with corresponding increase in moisture content. Bulk density was decreased from 662 kg/m3 to 610 kg/m3. Whereas, true density was decreased from 997 kg/m3 to 984 kg/m3.
Genomic epidemiology identifies emergence and rapid transmission of SARS-CoV-2 B.1.1.7 in the United States

As of January of 2021, the highly transmissible B.1. 1.7 variant of SARS-CoV-2, which was first identified in the United Kingdom (U.K.), has gained a strong foothold across the world. Because of the sudden and rapid rise of B.1. 1.7, we investigated the prevalence and growth dynamics of this variant in the United States (U.S.), tracking it back to its early emergence and onward local transmission. We found that the RT-qPCR testing anomaly of S gene target failure (SGTF), first observed in the U.K., was a reliable proxy for B.1. 1.7 detection. We sequenced 212 B.1. 1.7 SARS-CoV-2 genomes collected from testing facilities in the U.S. from December 2020 to January 2021. We found that while the fraction of B.1. 1.7 among SGTF samples varied by state, detection of the variant increased at a logistic rate similar to those observed elsewhere, with a doubling rate of a little over a week and an increased transmission rate of 35-45%. By performing time-aware Bayesian phylodynamic analyses, we revealed several independent introductions of B.1. 1.7 into the U.S. as early as late November 2020, with onward community transmission enabling the variant to spread to at least 30 states as of January 2021. Our study shows that the U.S. is on a similar trajectory as other countries where B.1. 1.7 rapidly became the dominant SARS-CoV-2 variant, requiring immediate and decisive action to minimize COVID-19 morbidity and mortality.
CORPORATE SOCIAL RESPONSIBILITY DISCLOSURE BY SUDANESE LISTED COMMERCIAL BANKS

The purpose of this study is to investigate the extent of Corporate Social Responsibility (CSR) disclosure in the annual reports of Sudanese commercial banks listed on the Khartoum Stock Exchange (KSE). The paper uses content analysis method by reviewing 61 annual reports of 10 listed banks over a period of 7 years. Content analysis used to analyze the size and methods of CSR disclosure in published annual reports, beside the areas of social responsibility that are disclosed. The study found that all banks covered by the study disclosed information regarding CSR in their annual reports. In terms of disclosure methods, the results showed that the banks used all methods (financial, quantitative and descriptive) to disclose social responsibility information, considering that most of the information contained in the annual reports was in a descriptive form. The study revealed that most banks disclosed information related to human resources and product and consumer, then community involvement, followed by disclosure of environmental issues. This research paper provides new evidence for the literature in this area and may encourage comparative studies on CSR studies from different perspective.

EFFECT OF CALCIUM AND BORON SPRAY ON GROWTH, YIELD AND DRIED GRATED QUALITY OF SOME CARROT CULTIVARS

The field work was carried out at the Experimental Farm of the Desert Research Center at Siwa Oasis, Marsa Matroh Governorate, during the two consecutive seasons of 2015/2016 and 2016/2017. The experiments were conducted to study the effect of calcium and boron as foliar application which were the combination of nine foliar spray application i.e., T1 (Ca 1g/ L), T2 (Ca 2g/L), T3 (B 1g/L), T4 (B 2g/L), T5 (Ca 1g/L+ B 1g/L), T6 (Ca 1g/L+ B 2g/L), T7 (Ca 2g/L+ B 1g/L), T8 (Ca 2g/L+ B 2g/L) and T9 control treatment (foliar spry by tap water) on growth, yield and chemical composition of tow carrot cultivars i.e., Nantes cv. and Fire wedge F1grown in sandy soil conditions. Also, evaluated the effect of oven and microwave drying methods on the quality aspects i.e., color, total carotenoids, vitamin C, vitamin E, total phenol and rehydration ratio. Results revealed that the highest values of plant height; shoot weight; shoot dry matter (%); root length; root dry mater (%); total yield/ fed; total root yield/ fed. ; marketable yield/fed; Ca (%) and total carbohydrates (%) were cleared with fire wedge Cv. in both growing seasons. But, the highest values of plant weight root diameter; root weight and values of unmarketable yield were obtained with Nantes Cv. , in both growing seasons. The highest values of all vegetative growth; root parameters; total root yield Ca (%) and total carbohydrates (%) were recorded with treatment T8 (foliar application by Ca 2g/l and B 2g/l) followed by T5 (foliar application by Ca 1g/l and B 1g/l) and no significant differences between them in both growing seasons. For the drying process, both oven and microwave drying methods improve the quality of the dried grated carrot samples where the total carotenoids, total phenol, vitamin C and vitamin E were enhanced, furthermore, a good color and rehydration ratio were achieved for both T8 and T5 treatment. Consequently, carrot crop could be stored all over the season by using drying process as a dried grated carrot in order to serve our home needs, in the same time, it considered to be a good value added product.
Green Synthesis and Characterization of CuO Nanoparticles Derived from Papaya Peel Extract for the Photocatalytic Degradation of Palm Oil Mill Effluent (POME)

In recent years, the green chemistry based-approach for the synthesis of nanoparticles has shown tremendous promise as an alternative to the costly and environmentally unfriendly chemically synthesized nanoparticles. In this study, copper oxide nanoparticles (CuO NPs) were synthesized through a green approach using the water extract of papaya (Carica papaya L.) peel biowaste as reducing as well as stabilizing agents, and copper (II) nitrate trihydrate salt as a precursor. The structural properties, crystallinity, purity, morphology, and the chemical composition of as-synthesized CuO NPs were analyzed using different analytical methods. The analytical results revealed that the synthesized CuO was observed as spherical-like in particles with measured sizes ranging from 85–140 nm and has monoclinic crystalline phase with good purity. The Fourier transform infrared (FTIR) spectroscopic results confirmed the formation of the Cu-O bond through the involvement of the potential functional groups of biomolecules in papaya peel extract. Regarding photocatalytic activity, the green-synthesized CuO NPs were employed as a photocatalyst for the degradation of palm oil mill effluent (POME) beneath the ultraviolet (UV) light and results showed 66% degradation of the POME was achieved after 3 h exposure to UV irradiation. The phytotoxicity experiment using mung bean (Vigna radiata L.) seed also showed a reduction of toxicity after photodegradation.

High quality ZnO film formation by CO2 laser annealing of buried films in SiO2 matrix

We have proposed the ZnO film annealing method using CO2 laser. We fabricated the layered structure to enhance the annealing effect. The sample structure was SiO2/ZnO/Quartz substrate. The ZnO film was deposited on quartz by a pulsed laser deposition and the SiO2 film was deposited on ZnO film by physical vapor deposition. We used photoluminescence measurement to investigate the optical property of ZnO film. We found that the optical property was improved in two steps. The first step was surface passivation effect of SiO2 coating and the second one was the annealing effect of CO2 laser. We analyzed the fabricated film for surface state by XPS and for crystallinity by TEM measurements. The change of ZnO surface state was observed when the SiO2 film was deposited on the ZnO film. The change of crystallinity of ZnO was observed after CO2 laser annealing. The crystallinity of ZnO before laser annealing seemed to be polycrystal, while the crystallinity of ZnO after laser annealing seemed to be single crystal.

Objective: This study aimed to explore the efficacy of hemodialysis and its effect on the nutritional status of patients with renal failure. Methods: A total of 92 patients admitted to our hospital due to rental failure form January 2017 to May 2019 were included as the study subjects and randomized into the study group (n=46) and the control group (n=46) according to a Random Number Table. They were treated by hemodialysis in the control group, hemodialysis and hemodiafiltration in the study group; and compared for indexes for renal function [urea (UA), serum creatinine (Cr), β2-microglobulin (β2-MG), kidney injury molecule 1 (KIM-1)], renal anemia [ferroprotein (SF), hemoglobin (Hb), hepcidin (HePC), and erythropoietin (EPO)], nutritional status [total protein (TP), albumin (Alb), content of calcium and phosphorus)], inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP)] and changes in quality of life before and after treatment, as well as incidences of adverse reactions. Results: After treatment, the observation group reported lower UA, Cr, β2-MG, KIM-1, phosphorus content, IL-6, TNF-α and hs-CRP, and higher SF, Hb, HePC, EPO, TP, Alb, calcium content, and scores of quality of life as compared with the conditions before treatment and with the control group (P<0.05). In comparison with the control group, the observation group also reported lower total incidence of adverse reactions (P<0.05). Conclusion: Hemodialysis and hemofiltration contributed to improved renal function, renal anemia and nutritional status, alleviated inflammatory reactions, enhanced quality of life and reduced the adverse reactions in patients with renal failure.
EFFECT OF PHOSPHORUS-ZINC (P-ZN) INTERACTION IN CALCAREOUS TORRIFLUVENT SOIL ON WHEAT (TRITICUM ASTEVUM L.) YIELD

A factorial pot experiment in split-split plot design was carried out to study the effect of phosphorus-zinc (P-Zn) interaction in calcareous Torrifluvent soil on wheat (Triticum astevum L.) yield, concentration and content of P and Zn in grain and straw. Phosphorus, as triple superphosphate (TSP), was added to soil at three rates (0, 30 and 60 mg P2O5 kg -1 soil, symbolized P0, P30 and P60, respectively). Zinc also was applied at three rates (0, 10 and 20 mg kg -1 soil, symbolized Zn0, Zn10 and Zn20, respectively). Two Types of zinc carriers were also examined, i.e. sulphate (Zn-Sulphate) and ethylene diamine tetra acetic acid (Zn-EDTA). Results showed a positive significant effect of P-Zn interaction on grain yield, straw yield, concentration and content of P in grain and straw, Zn content in grain. Whereas, the grain-Zn concentration decreased with increasing phosphorus level. The highest grain and straw yields were at the treatment P60×Zn20 -sulphate. The highest grain-P concentration (0.2501 mg kg-1) and content (20.72 g pot-1) were at the treatment P60×Zn10 -sulphate, while the lowest grain p concentration (1.973 mg kg-1) and content (10.70 g pot-1) were at P0×Zn0 treatment. Interaction treatment P60×Zn-sulphate was the superior in grain and straw yields, grain-P concentration and grain-P content per pot. No-significant effect was recorded among Zn sources at P30 in all the studied traits. Whereas significant differences in grain yield, grain-P content and grain-Zn content among the two sources at P60 treatments were found.
Rose petals with a novel and steady air bubble pinning effect in aqueous media

Many well-known natural superhydrophobic surfaces exhibit unique characteristics when immersed in the aqueous medium. In the present paper, the phenomenon of the steady pinning effect of air bubbles on a rose petal with a combination of hierarchical rough structures (i.e., micropapillae and nanofolds) is described. The pinning force of a 2 μL air bubble is ca. 101.2 μN, and the critical flow velocity of water leading the three-phase contact line (TPCL) to slide is as quick as 124.7 mm s−1. The artificial rose petal surface was prepared from polydimethlsiloxane (PDMS) by a casting technique. It has the same nanofolds and micropapillae as the rose petal surface, and shows a similar air bubble pinning effect. The pinning force and the critical flow velocity of the artificial rose petal surface are 140.7 μN and 156.7 mm s−1, respectively. Smooth and rough PDMS films with an ordered nanostructure or patterned microstructure are utilized to study the contribution of the micro/nano hierarchical structures to the air bubble pinning effect. Particularly, the facility that the captured air pockets in the nanostructure of the rose petals (ca. 500–600 nm in width on each micropapilla tip) coalesce with the air bubble is shown. The process where a periodic array of microstructures (diameter: 16 μm, height: 7 μm) construct “absorbed” islands to avoid the coalescence between the adjacent air pockets on the nanofolds is demonstrated as well. The important roles of the size and distribution of the microstructure of the rose petal in the air bubble pinning process are highlighted. This steady pinning effect induced on superhydrophobic surfaces with micro/nano hierarchical rough structures should spark further theoretical study on other bubble-related interfacial phenomena and should open a new avenue for their application in industrial processes, including the cleaning of boats contaminated by plankton and oil, reduction of drag friction on ships and submarine hulls, and the foaming control process.
Derivative Analysis of Value Added to Stock Returns at Jakarta Islamic Index

This study aims to examine the effect of value added derivative such as economic value added (EVA), market value added (MVA) and refined economic value added (REVA) on stock return with stock price as an intervening variable. The object of this study are all Islamic stocks listed in the Jakarta Islamic Index (JII) in the period 2014-2019. This study using purposive sampling method and obtained by 11 companies. Data processing using panel regression with common, fixed and random modelling approach. The results show that economic value added (EVA) has no effect either on stock prices or stock returns, market value added (MVA) affects the stock price and stock return, while refined economic value added (REVA) has no effect on both. Then, stock prices are only able to mediate the effect of market value added (MVA) on stock return.
