Algorithmic Approach for Learning a Comprehensive View of Online Users
No full textAbstractOnline users may use many different channels, devices and venues for any online user experience. To make all services such as web design, ads, web content, shopping, personalized for every user; we need to be able to recognize them regardless of device, channels and venues they are using. This, in turn, requires building up a comprehensive view of the user which includes all of their behavioral characteristics - that are spread all over these different venues. This would not be possible without having all behavioral related data of the user which requires the capacity of connecting the user all over the devices, and channels, so to have all of their behavior under a single view. This work is a major attempt in doing this using only behavioral data of users while protecting the user's privacy
Recommendation System Based on Complete Personalization
No full textAbstractCurrent recommender systems are very inefficient. There are many metrics that are used to measure the effectiveness of recommender systems. These metrics often include “conversion rate” and “click through rate”. Recently, these rates are in low single digit (less than 10%). In other words, for more than 90% of times, the model that the targeting system is based on, produces noise. The belief in this work is that the main problem leading to getting such unsatisfactory outcomes is the modeling problem. Much of the modeling problem could be represented and exemplified in treating users and items as member of clusters(segments). In this work, we consider full personalization of recommendation systems. We aim at personalization of users and contents simultaneously. Recommendations using baseline approach are inaccurate and targeting based on similarity-based recommendation (collaborative filtering) suffer from many disadvantages such as the neglect of interactive correlation. In this work, similarity based targeting has been combined with baseline approach and latent factor models and has been treated with adaptive regularization allowing complete personalization with respect to both users and items
Antifungal effects of various extracts from three Artemisia species against dermatophytosis fungal agents
No full textBackground and Aims: Dermatophytosis is one of the most important superficial infections in humans and animals worldwide. Artemisia species, as rich resources of natural products, have a high potential to treat many human diseases. The present study was conducted to investigate the antifungal effects of various extracts from three Artemisia species against dermatophyte fungi.
Materials and Methods: For in vitro study, aerial parts of Artemisia aucheri, Artemisia turcomanica, and Artemisia kopetdaghensis were extracted using five different solvents: petroleum ether, dichloromethane, ethyl acetate, ethanol, and hydro ethanol (50%), and were screened for their anti-dermatophytic effects against Epidermophyton floccosum, Trichophyton rubrum, Trichophyton verrucosum, and Microsporum canis. Afterward, the minimum inhibitory concentration (MIC) assay was performed according to the agar dilution method. The most active extracts were subjected to preliminary phytochemical studies.
Results: In the first screening of the extracts (concentration of 2 mg/ml), E. flucosum with no growth in the culture medium containing 13 extracts out of 15 was the most sensitive, and T. rubrum with no growth in 7 extracts from 15, including petroleum ether extracts obtained from A. aucheri, dichloromethane, ethylacetate and hydroethanolic extract obtained from A. turcomanica treatment; petroleum ether, ethylacetate and hydroethanolic obtained from A. kopetdaghensis treatment showed the highest resistance to the extracts. In the MIC results, the tested fungi were sensitive to all or some of the concentrations (ranging from 61.9 to 1981.1μg/ml). The lowest MIC value (61.9 μg/ml) was recorded for petroleum ether extract derived from A. turcomanica against E. floccosum. The preliminary phytochemical research results showed the presence of terpenoids and sterols in these extracts.
Conclusion: Some lipophilic components of the various extracts, especially petroleum ether extracts from A. aucheri, A. turcomanica, and A. kopetdaghensis, have in vitro anti-dermatophytic effects
Experimental and Numerical Study of Pile-to-Pile Interaction Factor in Sandy Soil
No full textAbstractIn structures to support large vertical and horizontal loads, piles are usually used in the form of closely spaced group. The piles in a group are not only affected by their individual loads transmitted from the pile cap, but also by additional loads transferred through the soil from the interference of neighboring piles. This group interaction influences the group stiffness, load-transfer mechanism and group settlement. In order to predict the response characteristics of pile groups, the interaction factors calculated using Mindlin's solution based on the theory of elasticity has been widely applied. The pile-to-pile interaction factor is defined as the ratio of displacements or rotations of an unloaded receiver pile to those of neighboring loaded source pile due to soil deformation. In this paper, a series of centrifuge model tests were carried out to examine the effect of soil relative density and pile spacing and pile tip condition on the interaction factor between two adjacent piles. Based on the results, soil relative density has a significant effect on the interaction between piles and thus it must be considered in the calculation of interaction factor. For this purpose, a correction to the Randolph and Wroth equation based on the test results was proposed in which the effect of soil relative density is contemplated. With an increase in the pile spacing, the value of interaction factor for all cases decreased. Compared to the effect of pile shaft, pile tip condition has a little effect on the interaction factor. The obtained results were also compared with those from a three-dimensional finite element analysis and a good agreement between the measured and the calculated results was observed
Morphology-induced spin frustration in granular BiFeO3 thin films: Origin of the magnetic vertical shift
No full text© 2018 Author(s). Pronounced room temperature vertical shifts in the magnetic hysteresis loops of granular, highly polycrystalline and ferromagnetic-like BiFeO3 thin films are observed upon field-cooling from a temperature above the Néel temperature of bulk BiFeO3. This is ascribed to the interplay between the preferential alignment, established by the field-cooling process, of the net magnetic moment, which arises from uncompensated antiferromagnetic spins, and the pinning of a fraction of these spins at the particle boundaries. Conversely, field-cooling of an epitaxially grown BiFeO3 film results in no vertical shift, confirming the effective role played by the particle boundaries (i.e., morphology) of the granular-like BiFeO3 films in the process of spin frustration.sponsorship: This work was financed by the Research Foundation-Flanders (FWO) and the KU Leuven Concerted Action (GOA/09/006 and GOA/14/007) programs.

Overview of the Factors Music Making in Tamhidat by Ein al-Ghozat Hamedani
No full textAbstract
Figures of speech in addition to their aesthetic functions have different effects on words. Internal music is one of the effects of figures of speech which can play an important role in beautifying the word and its effect on the audience. The internal music comes with the use of verbal figures of speech. Figures that make words related by similarity or uniformity of vowels and consonants and create sensible alliteration. Categories of palilogy, alliteration, parallelism, pun and riming prose are among the figures of speech that play a major role in creating internal music of the poem. In this study, with a descriptive-analytical approach, we discuss the roll of music making factors in Tamhidat as an example of prose poem. The language of Ein ol-Ghozat in Tamhidat is preachy and didactical and in an addressing mode. Despite the intensity and sharpness of his speech, he speaks simple language with his audience. However, his words are in some cases melodious that influences audience and increases its penetration in the listener. The music of his words is natural so the listener can feel it with his spirit and takes its effect. Well syntagmatic arrangement of words is one of his language features that is based on music and phonemes' melody. This music gives words importance and predominance and makes Tamhida's prose a kind of prose poem. Applying some of the subtle and tiny musical elements such as parallelism (paronomasia /pun) makes the music of book more effective and catching. In other words, harmony of sounds and synchronization through which prose becomes rhythmic and melodious is one of the aesthetic aspects of the mystical prose of Ein ol-Ghozat that arises from his word's music and special intonation, so as human nature accepts it and enjoys reading. This word music is found in the form of alliteration, pun, repetition, and meter in important parts of his speech that sometimes becomes close to prosodic meter. In Ein ol-Ghozat's prose without feeling prosodic meter by listener, a wave of intonation and meter dominates resulted from alliteration and rhyme, and proximity of the number of syllables in every symmetry and perhaps likeness and nearness of the number of syllables in all or parts of the symmetries.
Repetition as a key element of the internal music is one of Ein ol-Ghozat's stylistic characteristic. Repetitions are seen in three forms in Ein ol-Ghozat languages. 1- Alliteration, this group consists of various kinds of pun, rhyme, repetition, etc. 2- Parallelism: Repetition of words or phrases. 3- Palilology: Repetition of word: This form is one of the most important and aesthetic repetition in Tamhidat that in addition to making prose integrated, is effective in conveying the concept and content of the message of Ein ol-Ghozat, as repetition of the words "Alas," " O’ Friend," and "O’ Dear" in several phrases has a great influence in stimulation of feeling and inculcation emotion in the reader.
Alliteration: One of the most important aspects of aesthetics in the mystical prose of Ein ol-Ghozat are sound harmony and alliteration that can be mainly found in pun/ paronomasia and riming. Usage of rhyme in all Tamhidat is not in the same level. Wherever discussion is didactic and reasoning, it is not generally riming, but where the subject is stories and anecdotes and analogies or becomes emotional, usually is riming. One manifestation of this figure is short sentences and aphorisms, whether the word is quotation of an old or an important person or whether the author expresses his own word.
Apart from these, Ein ol-Ghozat has worked other ways to enrich his word's music. The most important of these methods are:
Bringing words that at least their initials are co-voiced. Such as: "Ebtela" and "Emtehan"
Phonemes processing: a kind of internal music is repetition and sameness of consonants and vowels. This figure in some cases, with creating a specific internal music, highlights the phrases and helps to conveying the message and gives pleasure to the audience.
Bringing together words that make a pun is another species of alliteration in the language of Ein ol-Ghozat. This figure of speech is one of the best examples of creating and enhancing music in words or sentences.
Bringing together the co-meter terms is one of other species of alliteration in Tamhidat.
Repetition of words or phrases, are of those categories that is used in the mystical prose of Ein ol-Ghozat and is one of the stylistic features and music making elements of his Word. Repetition in Ein ol-Ghozat's language, sometimes have artistic and rhetorical aspects that helps his prose being rhythmic and is effective in conveying the meaning and intention of the speaker. Ein ol-Ghozat while repeats thoughts and beliefs of the mystics, repeats words and combinations in the various types, so that he not only raises the words' musical level and makes it melodious, but also increases the rhythmic role of his own speaking. Sometimes this repetition in the form of word or phrase in the end of sentence comes symmetrically, it functions like radif in hemistiches and if in the terms of syllables number be long, makes an intonation in the words too

Antioxidant defense and secondary metabolites concentration in hyssop (Hyssopus officinalis L.) plants as affected by salt stress
No full textSalt stress is one of the major limiting factors for plant production, and the quality of medicinal plants is also affected by soil salinity. Hyssop (Hyssopus officinalis L.) plants were cultivated for four weeks in perlite: sand and irrigated with Hoagland nutrient solution containing 0, 50, 100, 150, and 200 mM NaCl. Plants growth was decreased by salt stress while the leaf relative water content was not affected, and the chlorophyll content decreased only by the highest salt concentration (200 mM). Sodium was accumulated at small amounts, indicating a high ability of this species to exclude salt. Soluble sugars and proline were accumulated up to 1.6 and 4.5 fold, respectively. The antioxidant enzymes activity (peroxidase, catalase, ascorbate peroxidase) were increased by the salt treatments, particularly in the leaves. The levels of secondary metabolites (saponins, phenolics, flavonoids, anthocyanins, and iridoids) were all increased under salt stress, and the total antioxidant capacity of alcoholic extract of the leaves and roots was significantly higher in the salt-treated compared with control plants. Our results showed that hyssop is a salt-tolerant species, and the quality of this medicinal plant is improved when grown under saline conditions
The Factors Music Making in ''Tamhidat Eyn Ol Ghozat Hamedani'' in a glance
No full textInnovative industries In addition to their aesthetic functions have different effects on words. Endogenous music is one of the Innovative industries effects which can play an important role in beautifying the word and its effect on the audience. The Endogenous music is the music that comes with the use of verbal Innovative industries. Industries that are caused words by similarity or congruence of vowels and consonants more related to each other and created sensible phonetic relationship between them. Categories of frequency, phonology, pun and rhyme are among the Innovative industries that play a major role in creating the endogenous music of poem. In this study, with a descriptive - analytical approach the roll of music maker preparations as an example of a prose poem are discussed.The language of Ein ol-Ghozat in lingual preparations is of preacher and educational that has a addressing mode. He speaks with unadorned language with his audience. However, his words are coupled in some cases with rhythmic language that influences audience despite the intense and sharp in speech and makes his word penetration double in the listener. His Words music is natural music that the listener can feel it with their lives and takes effect of it. One feature of this language is order in the arrangement and companion construction of words that based on music and phonemes music. This music The Music gives importance and Individuation to each word and making preparations prose to a kind of prose poem. Applying some of the thin musical nuances such as the balances (Incrustation and puns) makes the music of book more effective and welcome catching. In other words, coordination of audio and verbal and synchronization that through them prose becomes rhythmic and melodic is one of the beautiful aspects of the mystical prose of Ein ol-Ghozat that arises from his words music and a makes special song, as nature accepts and enjoys its reading. This word music is seen in the garb of the phonetic and pun, repetition, and rhythm being in important parts of speech that close sometimes to prosodic weight. In the prose of Ein ol-Ghozat without feeling prosodic weight by listener, a Wave of song and weight dominates that is a result of phonetic and rhymes, and being Near a number of syllables in each mirror to each other and perhaps in all or part of the mirrors, the number of syllables is the same or close.Replication as a key element of the endogenous music is one of Ein ol-Ghozat 's stylistic characteristic. Replications are seen in three forms in Ein ol-Ghozat languages. 1- Phonetic repetition, this group consists of repeating the pun, rhyme and phoneme layout and etc. 2- Repetition of words or phrases. 3- Word Repetition: The Repetition is one of the most important and beautiful art repetition in preparations that in addition to give the integrated to prose is effective in order to better instill of the concept and content of the message of Ein ol-Ghozat, As repetition of the words "Alas," " O’ Friend," and "O’ Dear" in different phrases has a great influence in stimulation of feeling and induction emotional state to the reader's.Phonetic Repetition: One of the most important aspects of beauty in the mystical prose of Ein ol-Ghozat are voice and phonetic coordination that its peak can be found in a pun and rhyme and Incrustation. The using of rhyme in preparations is not the same. In a place that discussion is education and reasoning generally speaking, is not a poem, but in where that speaking is about stories and anecdotes and analogies or become emotional; usually poems used. One manifestation of this item is short sentences and aphorisms, whether in a place that the word is quote by an old or an important person or whether the author express his own speaks.Apart from these, Ein ol-Ghozat has worked other ways to enrich his words music. The most important of these methods are:•Bringing words that at least their initials are co-voiced. Such as: suffering and testing •Phonemes processing: a kind of endogenous music is repetition and consistency of consonants and vowels that in some cases, with creating the specific endogenous music cause highlighting the phrases and helps to conveying the message and delight of the audience. •Bringing together words that together make a pun is another species of Repetition in the language of Ein ol-Ghozat. This innovative array is One of the best examples of musical creating and growing in vocabulary or sentences. •Bringing together the co-Weight terms is one of the species of phonetic repetition in preparations. Repetition of words or phrases, are of those issues that is used in the mystical prose of Ein ol-Ghozat and is one of the stylistic features and music making elements of his Word. Repeat in Ein ol-Ghozat language, sometimes have artistic and rhetorical aspects that helps to being rhythmic of Ein ol-Ghozat prose and is effective in conveying the meaning and intention of the speaker. Ein ol-Ghozat meanwhile of repetition of thoughts and beliefs of the mystics, repeats words and combinations in the various types, while raising the words musical level and its making it melodic, increase the unilateral obligation role of his own speaking. Sometimes this repetition in the form of word or phrase in the end of sentence comes symmetrically, such that is in the order of the rows is hemistich and If in the terms of syllables number be long, makes a song in the words to
