Abstract:
The wide range and complexity of cosmetic formulations currently available on the market poses a challenge from an analytical point of view. In addition, during cosmetics manufacture, impurities coming from raw materials or formed by reaction of different organic compounds present in the formulation may be present. Their identification is mandatory to assure product quality and consumer health. In this work, micro-matrix solid-phase dispersion (μMSPD) is proposed as a multi-target sample preparation strategy to analyze a wide number of unexpected families of compounds including polycyclic arom

Abstract:
Modeling student knowledge is critical in adaptive learning environments. Predictive student modeling enables formative assessment of student knowledge and skills, and it drives personalized support to create learning experiences that are both effective and engaging. Traditional approaches to predictive student modeling utilize features extracted from students’ interaction trace data to predict student test performance, aggregating student test performance as a single output label. We reformulate predictive student modeling as a multi-task learning problem, modeling questions from student test

Abstract:
This paper is devoted to the setting and analysis of a Petrov–Galerkin wavelet-fictitious domain numerical method for the approximation of the solution of multi-dimensional parabolic equations on a general domain. In this method, the original parabolic equation, set on a domain ω, is first discretized in time using a finite difference scheme. At each time step, the corresponding elliptic equation on ω is transformed into a saddle point problem on a functional space defined on a bigger but simply shaped domain Ω where the initial boundary conditions on ω are enforced using surface Lagrange mult

AbstractThe paper proposes a multi-domain approach to the optimization of the dynamic response of an underactuated vibrating linear system through eigenstructure assignment, by exploiting the concurrent design of the mechanical properties, the regulator and state observers. The approach relies on handling simultaneously mechanical design and controller synthesis in order to enlarge the set of the achievable performances. The underlying novel idea is that structural properties of controlled mechanical systems should be designed considering the presence of the controller through a concurrent app

Abstract. In this study, ship-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements were performed in the East China Sea (ECS) area in June 2017. The tropospheric slant column densities (SCDs) of nitrogen dioxide (NO2), sulfur dioxide (SO2), and formaldehyde (HCHO) were retrieved from the measured spectra using the differential optical absorption spectroscopy (DOAS) technique. Using the simple geometric approach, the SCDs of different trace gases observed at a 15∘ elevation angle were adopted to convert into tropospheric vertical column densities (VCDs). During

Abstract:
Deminutive vocabulary is a vivid means of emotional and allegorical expression of a literary text, especially when it comes to Ukrainian folk songs. The need for its further study in terms of word formation, semantics and expressive possibilities in the literary text will clarify the idea of reduction as a word-forming category, the peculiarities of its use in Ukrainian folk songs. High derivational activity of diminutive suffixes in the modern Ukrainian language is a manifestation of the nominative function – the desire to call small objects (rarely – minor phenomena of reality) a derivative with a diminutive formant. With the help of diminutive suffixes the aesthetic function of the word is realized – the desire to give the lexical unit of expression, to introduce into it an additional shade of expression. Diminutives often used in adult language addressed to children, and in children's language. Each group of words of subjective evaluation characterized by certain forms used in the formation of derivatives and express an inexhaustible number of different shades of meaning. Derivational analysis can be complicat by the specific possibilities of context and intonation, as in language and speech there may be an erasure of the basic meaning of the subjective-evaluation token and its transition from one group of words of subjective evaluation to another. The scientific novelty of the study lies in the multi-vector exploration: an attempt to generalize the idea of diminutives as a word-forming category, including typical suffixes with which they are formed, their word-forming meanings and productivity, types of creative bases, and to trace the stylistic role of diminutives on Ukrainian folk songs. The relevance of the proposed exploration determined by the insufficient development of the topic of diminutive derivation in song folklore, the importance and role of diminutives in Ukrainian folk songs. The connection of the researched topic with the general problems of Ukrainian stylistic word formation also seems to be theoretically important and relevant. The aim of the research is to reveal the lexical-semantic and word-forming features of diminutives, as well as their stylistic load in the texts of Ukrainian folk songs. To achieve this goal it is necessary to perform the following research tasks: to outline the theoretical foundations of the study of diminutives as a type of derived words in modern linguistic literature; to characterize the specifics of Ukrainian diminutives; to carry out semantic classification of the considered diminutives; analyze the grammatical and structural properties of diminutives; to determine the stylistic role of diminutives in Ukrainian folk songs. Research methods: the main thing in the work is the descriptive method, with its universal methods of observation, systematization and interpretation of linguistic facts and phenomena. The presentation of the researched material is subject to clear logicization: substantiation of theoretical bases, presentative-analytical presentation of the fact, formulation of the concluding part.

Abstract:
The formulation of efficient supervised learning algorithms for spiking neurons is complicated and remains challenging. Most existing learning methods with the precisely firing times of spikes often result in relatively low efficiency and poor robustness to noise. To address these limitations, we propose a simple and effective multi-spike learning rule to train neurons to match their output spike number with a desired one. The proposed method will quickly find a local maximum value (directly related to the embedded feature) as the relevant signal for synaptic updates based on membrane potentia
