description: The profusion of online news articles makes it difficult to find interesting articles, a problem that can be assuaged by using a recommender system to bring the most relevant news stories to readers. However, news recommendation is challenging because the most relevant articles are often new content seen by few users. In addition, they are subject to trends and preference changes over time, and in many cases we do not have sufficient information to profile the reader. In this paper, we introduce a class of news recommendation systems based on context trees. They can provide high-quality news recommendation to anonymous visitors based on present browsing behaviour. We show that context-tree recommender systems provide good prediction accuracy and recommendation novelty, and they are sufficiently flexible to capture the unique properties of news articles.

description: The Heun function generalizes all well-known special functions such as Spheroidal Wave, Lame, Mathieu, and hypergeometric_2F_1,_1F_1 and_0F_1 functions. Heun functions are applicable to diverse areas such as theory of black holes, lattice systems in statistical mechanics, solution of the Schrodinger equation of quantum mechanics, and addition of three quantum spins. In this paper I will apply three term recurrence formula (Choun, Y.S., arXiv:1303.0806., 2013) to the power series expansion in closed forms of Heun function (infinite series and polynomial) including all higher terms of A_n's. Section three contains my analysis on applying the power series expansions of Heun function to a recent paper. (R.S. Maier, Math. Comp. 33, 2007) Due to space restriction final equations for the 192 Heun functions are not included in the paper, but feel free to contact me for the final solutions. Section four contains two additional examples using the power series expansions of Heun function. This paper is 3rd out of 10 in series "Special functions and three term recurrence formula (3TRF)". See section 5 for all the papers in the series. The previous paper in series deals with three term recurrence formula (3TRF). The next paper in the series describes the integral forms of Heun function and its asymptotic behaviors analytically.

Subjects: subject: Plant sciences.

description: A number of approaches were adopted to clone pea MTase cDNAs. The only successful approach, however, was PCR amplification of pea MTase-specific segments using degenerate primers, that were designed mainly according to the conserved motifs IV and VI of mouse MTase. A downstream antisense primer based on motif VI was used to prime first-strand cDNA synthesis from pea total RNA. This was then amplified using the same primer in combination with a sense primer designed according to motif IV. Several of the PCR products which were amplified were cloned into pBluescript and then sequenced. Only one type of PCR product was found to be MTase-specific upon translation of the sequences. On comparison with the database, this PCR product was found to share the highest homology with Arabidopsis MTase, followed by mouse and human MTases. No other MTase- specific PCR product was identified out of a total of 18 independent clones that were sequenced. Only one MTase mRNA (of 5.0 kb in length) was identified upon hybridisation of the cloned pea MTase-specific PCR product to a northern blot of pea poly(A)+ RNA. The 3' end of the pea MTase cDNA (corresponding to most of the catalytic domain) was cloned using a 3' RACE strategy and Pfu polymerase. Seven independent clones were mapped, and three were sequenced. The three clones were found to be absolutely identical in sequence, except for at the extreme 3' end, where the sites used for polyadenylation were found to be different for each clone. The nucleotide sequence of the 3' RACE products was also found to match that of the original MTase-specific PCR products in the region between motifs IV and VI. Again, the translated sequence of the 3' RACE product shared the highest homology with Arabidopsis MTase. No evidence for alternative splicing in the 3' end of the pea MTase transcript was found. Developmental changes in the steady state levels of pea MTase mRNA were investigated by hybridisation of one of the cloned PCR products to a northern blot of total RNA extracted from different tissues from pea seedlings, taken at different stages of development. The strength of the hybridisation signal was found to parallel the changes in MTase specific activity (Yesufu et ai, 1991), being highest in rapidly dividing tissues. To determine whether a family of related pea MTase genes exists in pea, the 3' RACE product was hybridised at moderate stringency to a Southern blot of pea genomic DNA digested with various restriction enzymes insensitive to methylation at CpG and CpNpG sites. The results were consistent with the presence of only one type of MTase gene in pea.

description: Mathieu ordinary differential equation is of Fuchsian types with the two regular and one irregular singularities. In contrast, Heun equation of Fuchsian types has the four regular singularities. Heun equation has the four kind of confluent forms: (1) Confluent Heun (two regular and one irregular singularities), (2) Doubly confluent Heun (two irregular singularities), (3) Biconfluent Heun (one regular and one irregular singularities), (4) Triconfluent Heun equations (one irregular singularity). Mathieu equation in algebraic forms is also derived from the Confluent Heun equation by changing all coefficients. In this paper I apply three term recurrence formula [arXiv:1303.0806] to the power series expansion in closed forms of Mathieu equation for infinite series and its integral forms including all higher terms of A_n's. One interesting observation resulting from the calculations is the fact that a modified Bessel function recurs in each of sub-integral forms: the first sub-integral form contains zero term of A_n's, the second one contains one term of A_n's, the third one contains two terms of A_n's, etc. Section 5 contains two additional examples of Mathieu function. This paper is 5th out of 10 in series "Special functions and three term recurrence formula (3TRF)". See section 6 for all the papers in the series. Previous paper in series deals with asymptotic behavior of Heun function and its integral formalism [arXiv:1303.0876]. The next paper in the series describes the power series expansion in closed forms of Lame equation in the algebraic form and its integral forms [arXiv:1303.0873].

Safety Aware Reinforcement Learning by Identifying Comprehensible Constraints in Expert Demonstrations
Creators: name: Müller, Leopold
name: Böcking, Lars
name: Färber, Michael
Publisher: name: CEUR-WS.org
Year: 2022

description: When used in real-world environments, agents must meet high safety requirements as errors have direct consequences. Besides the safety aspect, the explainability of the systems is of particular importance. Therefore, not only should errors be avoided during the learning process, but also the decision process should be made transparent. Existing approaches are limited to solving a single problem. For real-world use, however, several criteria must be fulfilled at the same time. In this paper we derive comprehensible rules from expert demonstrations which can be used to monitor the agent. The developed approach uses state of the art classification and regression trees for deriving safety rules combined with concepts in the field of association rule mining. The result is a compact and comprehensible rule set that explains the expert’s behavior and ensures safety. We evaluate our framework in common OpenAI environments. Results show that the elaborated approach is able to identify safety-relevant rules and imitate expert behavior especially in edge cases. Evaluations on higher dimensional observation spaces and continuous action spaces highlight the transferability of the approach to new tasks while maintaining compactness and comprehensibility of the rule set.

Predictions in multifield models of inflation

description: This paper presents a method for obtaining an analytic expression for the density function of observables in multifield models of inflation with sum-separable potentials. The most striking result is that the density function in general possesses a sharp peak and the location of this peak is only mildly sensitive to the distribution of initial conditions. A simple argument is given for why this result holds for a more general class of models than just those with sum-separable potentials and why for such models, it is possible to obtain robust predictions for observable quantities. As an example, the joint density function of the spectral index and running in double quadratic inflation is computed. For scales leaving the horizon 55 e-folds before the end of inflation, the density function peaks at n_{s}=0.967 and α=0.0006 for the spectral index and running respectively.

Creators: name: Trofimov, Alexandra
Publisher: name: University of Kent
Year: 2016

description: Sometimes, we accept "I'm sorry, I didn't know" as an excuse, but at other times we do not. When are we justified in claiming that a person should have known better and that they are, therefore, responsible and blameworthy for their ignorant wrongdoing? Through a detailed investigation of ignorant wrongdoing, I establish conditions of responsibility for ignorant wrongdoing that not only provide a coherent justification for many of our standard judgements regarding responsibility and blame but also enable me to defend those judgements against objections and revisionist perspectives. I argue that: (1) Persons are responsible for their ignorant wrongdoing if and only if they are responsible for their ignorance. And that: (2) Persons are responsible for their ignorance if and only if: (a) They possess the rational capacity to accurately appreciate the relevant reasons. (b) There are no limitations in their circumstances that make it unreasonably difficult for them to accurately appreciate the relevant reasons. I argue that if both conditions (a) and (b) are met, then it is reasonable to claim that a person should have known better because they have had fair opportunity to avoid both their ignorance and their wrongdoing that results. In developing this account of responsibility for ignorant wrongdoing, I argue that internalist accounts of practical reasons are untenable from the perspective of responsibility and blame.

description: Zamolodchikov's famous analysis of the RG trajectory connecting successive minimal CFT models $M_p$ and $M_{p-1}$ for $p\gg 1$, is improved by including second order in coupling constant corrections. This allows to compute IR quantities with next to leading order accuracy of the $1/p$ expansion. We compute in particular, the beta function and the anomalous dimensions for certain classes of fields. As a result we are able to identify with a greater accuracy the IR limit of these fields with certain linear combination of the IR theory $M_{p-1}$. We discuss the relation of these results with Gaotto's recent RG domain wall proposal.

description: We study a continuous-time, finite horizon, stochastic partially reversible investment problem for a firm producing a single good in a market with frictions. The production capacity is modeled as a one-dimensional, time-homogeneous, linear diffusion controlled by a bounded variation process which represents the cumulative investment-disinvestment strategy. We associate to the investment-disinvestment problem a zero-sum optimal stopping game and characterize its value function through a free-boundary problem with two moving boundaries. These are continuous, bounded and monotone curves that solve a system of non-linear integral equations of Volterra type. The optimal investment-disinvestment strategy is then shown to be a diffusion reflected at the two boundaries.

journaling

description: Background: Nursing students often experience anxiety and stress from the expectations to develop clinical reasoning skills, internalize new knowledge, and learn to care for patients. Previous research has proposed reflective thinking as a tool to lessen anxiety and promote metacognition. This article examines the role of journaling in promoting reflection among undergraduate nursing students. Method: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were used to conduct the review. Concepts for journaling and nursing students were searched in four databases. Data were extracted from 19 sources to identify study type, participants, descriptions of journaling, and findings. Results: Studies took place in a variety of clinical and classroom settings; the majority used a guided format. Various frameworks and tools were used to provide conceptual support. Conclusion: Most studies found journaling to be effective in promoting reflection and the development of clinical judgment and emotional competency. However, more studies are needed to develop appropriate rubrics for assessment.

description: We consider the problem of exploiting the microgenerators dispersed in the power distribution network in order to provide distributed reactive power compensation for power losses minimization and voltage regulation. In the proposed strategy, microgenerators are smart agents that can measure their phasorial voltage, share these data with the other agents on a cyber layer, and adjust the amount of reactive power injected into the grid, according to a feedback control law that descends from duality-based methods applied to the optimal reactive power flow problem. Convergence to the configuration of minimum losses and feasible voltages is proved analytically for both a synchronous and an asynchronous version of the algorithm, where agents update their state independently one from the other. Simulations are provided in order to illustrate the performance and the robustness of the algorithm, and the innovative feedback nature of such strategy is discussed.

description: The Washburn law has always played a critical role for ceramics. In the microscale, surface forces take over volume forces and the phenomenon of spontaneous infiltration in narrow interstices becomes of particular relevance. The Lattice Boltzmann method is applied in order to ascertain the role of surface reaction and subsequent deformation of a single capillary in 2D for the linear Washburn behavior. The proposed investigation is motivated by the problem of reactive infiltration of molten silicon into carbon preforms. This is a complex phenomenon arising from the interplay between fluid flow, the transition to wetting, surface growth and heat transfer. Furthermore, it is characterized by slow infiltration velocities in narrow interstices resulting in small Reynolds numbers that are difficult to reproduce with a single capillary. In our simulations, several geometric characteristics for the capillaries are considered, as well as different infiltration and reaction conditions. The main result of our work is that the phenomenon of pore closure can be regarded as independent of the infiltration velocity, and in turn a number of other parameters. The instrumental conclusion drawn from our simulations is that short pores with wide openings and a round-shaped morphology near the throats represent the optimal configuration for the underlying structure of the porous preform in order to achieve faster infiltration. The role of the approximations is discussed in detail and the robustness of our findings is assessed.

description: Title: An inquiry into the supports and training available to specialist fertility nurses in the delivery of bad news to patients. An Action Research Project. Background: Specialist fertility nursing is an area of medicine which frequently involves the delivery of bad news to patients. Nurses may have to tell patients that a cycle of fertility treatment must be cancelled, that a round of treatment has not been successful or that a pregnancy is not viable. Research suggests that this is a stressful element of the role of specialist fertility nursing. Problem Description: There is a lack of training and support specific to the challenges of working as a specialist fertility nurse. Methods: Phases of action research were used in this project with pre -planning, construction and planning action being the focus of this cycle. Process: Participants completed an anonymous survey and then semi structured face-to-face interviews were conducted with four nurses. Participants were recruited through the clinic where the researcher works. Interviews were transcribed verbatim and thematic analysis of the data was conducted. Results: Prominent themes were established. Nurses reported experience matched existing research in this area that training and support in the area of the delivery of bad news to patients was important, and that further training and support would be welcomed. A plan for improvements to training and support emerged as a result of this research and this will be presented to all stakeholders to engage with them for the purposes of implementation of the plan.

By way of an application, we show that all spherical representations are self-dual in type AIII|AIII.

description: Persistent homology is a method for probing topological properties of point clouds and functions. The method involves tracking the birth and death of topological features (2000) as one varies a tuning parameter. Features with short lifetimes are informally considered to be "topological noise," and those with a long lifetime are considered to be "topological signal." In this paper, we bring some statistical ideas to persistent homology. In particular, we derive confidence sets that allow us to separate topological signal from topological noise.

description: Background: Perinatal loss is very common in maternity settings. Bereavement care has to be offered in the most sensitive way to bereaved parents. Therefore, it is important that staff are supported and appropriately trained around bereavement care provision and the memory-making process to demonstrate knowledge, competence and confidence to bereaved parents. Problem description: Staff education around all aspects of bereavement support and memory-making is necessary to provide a high standard of bereavement and to ensure bereaved parents leave the hospital with a completed memory box. Methodology: Action research was used in this project in conjunction with the PDSA-cycle. Both action research and the PDSA-cycle are used in healthcare settings to improve quality of care. Data was collected via a survey questionnaire. Process: Data was collected over 4 weeks and 63 responses were logged thereafter. The platform survey monkey generated frequencies and percentages for each question. Content analysis was used to analyse open-ended questions. Results: A good overview of staff knowledge and skills around bereavement care and memorymaking was recorded and gaps in staff support were identified. The results were presented to and discussed with senior management to ensure awareness of staff needs around bereavement support provision. Conclusion: The research findings are consistent with current literature. The findings provide a perfect opportunity to plan and develop future action research cycles to improve bereavement care and bring chance to the organisation. Using action research methodology and a questionnaire for data collection was proven to be effective in this study.

description: A procedure to obtain single-electron wavefunctions within the tight-binding formalism is proposed. It is based on linear combinations of Slater-type orbitals whose screening coefficients are extracted from the optical matrix elements of the tight-binding Hamiltonian. Bloch functions obtained for zinc-blende semiconductors in the extended-basis spds* tight-binding model demonstrate very good agreement with first-principles wavefunctions. We apply this method to the calculation of electron-hole exchange interaction, and obtain the dispersion of excitonic fine structure of bulk GaAs. Beyond semiconductor nanostructures, this work is a fundamental step toward modeling many-body effects from post-processing single particle wavefunctions within the tight-binding theory.

description: Background Most people manage to adapt to loss without the need for professional support, however, grief is complex and can have complicating consequences for some. Research into bereavement care highlights the importance of assessing bereavement care needs and providing concordant support where necessary. Rationale: Due to the specific nature of loss and bereavement care, policies are recommended for services that provide support to the bereaved. Policies provide guidelines for when support is appropriate and identifies who benefits most from interventions. Aim: To create a Loss and Bereavement Care Policy for service users in a Cancer Support Service. Method: An action research design using co-operative inquiry was implemented to create the policy in cycles of planning, action, and reflection. A policy analysis tool was used as a guide during the policy development process and to evaluate the draft policy at the end of the process. Data collection and analysis was undertaken, data were policy issues discussed, dilemmas faced, solutions found, actions planned and reflections on action. Results: A draft policy was created in an action research cycle and plans are in place to implement it in clinical practice in the next action research cycle over the next six months. Holding therapy, the role complementary therapists play in care and grief assessment emerged as themes from the inquiry. Remuneration was not a necessary motivation to bring subcontractors into the co-operative inquiry. Conclusion: Co-operative inquiry and using a policy analysis tool as a policy development guide proved effective when creating the policy.

description: Στόχος της παρούσας διπλωματικής εργασίας είναι να διερευνηθεί σε τι ποσοστό θα μπορούσε να αυτονομηθεί ενεργειακά, ένα κτίριο γραφείων, επιτυγχάνοντας παράλληλα οπτική και θερμική άνεση για την παροχή ιδανικών συνθηκών εργασίας, μέσα από την ενσωμάτωση Φωτοβολταϊκών πλαισίων σε ειδικά σχεδιασμένα σκίαστρα.
Το κτίριο αυτό υποθετικά ανήκει στην περιοχή των Χανίων της Κρήτης, και στην παρούσα εργασία εξετάζεται η κάλυψη των αναγκών των γραφείων του κτιρίου που είναι προσανατολισμένα στη Δύση. Με αυτά τα δεδομένα και για τη θερινή περίοδο, όπου στα Μεσογειακά κλίματα απαιτείται σε μεγαλύτερο ποσοστό η εξισορρόπηση των θερμικών φορτίων και η αποφυγή έντονου φωτισμού, σχεδιάστηκαν σκίαστρα.
Πραγματοποιήθηκαν έπειτα, σε πρώτη φάση, προσομοιώσεις για τις ανάγκες σε ενέργεια του γραφείου και για την παραγωγή των Φ/Β στις συνθήκες για τις οποίες σχεδιάστηκαν, ενώ σε δεύτερη φάση για διαφορετικές περιοχές και προσανατολισμό.
Τα σκίαστρα κατατάχθηκαν σύμφωνα με την αποτελεσματικότητα τους, και κρίνεται ότι θα μπορούσαν να χρησιμοποιηθούν και σε άλλες περιοχές, με δυτικό προσανατολισμό, με μικρές μειώσεις στην απόδοση. Σε αλλαγή προσανατολισμού παρατηρείται μεγαλύτερη μείωση στην απόδοση. ενώ εξήχθησαν και γενικότερα συμπεράσματα για τα είδη των σκιάστρων που ενδείκνυνται σε Μεσογειακά κλίματα, δυτικό και ανατολικό προσανατολισμό.
Η εξέταση του ενεργειακού ισοζυγίου υπό το σχεδιασμό σκιάστρων με ενσωματωμένα Φ/Β αποτελεί ενδεδειγμένη λύση εδώ και πολλά χρόνια στις ανεπτυγμένες χώρες, ενώ η προσομοίωση με τα λογισμικά που χρησιμοποιούνται, έχει αποδειχθεί από προηγούμενες μελέτες [Mandalaki et al., 2013] ότι παρέχουν αποτελέσματα με πολύ ικανοποιητική ακρίβεια.

description: Quantum mechanics allows systems to be entangled with each other, which results in stronger than classical correlations. Many methods of identifying entanglement have been proposed over years, most of which are based on violating some statistical inequalities. In this work we extend the idea due to Hardy, in which entanglement is not identified with use of statistical inequalities, but by simultaneous satisfaction of certain conditions. We show that the new variant of the Hardy paradox relying on marginal probabilities can be resolved only by true multipartite entangled states. Also, the state resolving this paradox for given local measurements is pure and unique in case of qubit collections.

title: Αξιοποίηση της ηλιακής ακτινοβολίας στην απολύμανση παθογόνων μικροοργανισμών με ετερογενή φωτοκατάλυση

description: Η τάση των τελευταίων ετών για εναλλακτικούς τρόπους απολύμανσης υδατικών λυμάτων έχει φέρει στο προσκήνιο  νέες μεθόδους απολύμανσης φιλικές προς το περιβάλλον, μια εκ των οποίων είναι η φωτοκατάλυση η οποία ανήκει στις λεγόμενες  «Προχωρημένες Οξειδωτικές Μεθόδους Αντιρρύπανσης» (ΠΟΜΑ). Με τον όρο αυτό εννοούνται εκείνες οι τεχνολογίες η αποτελεσματικότητα των οποίων στηρίζεται στην παραγωγή ριζών υδροξυλίου (ΟΗ.), ιδιαίτερα δραστικών οξειδωτικών μέσων. Στην παρούσα διπλωματική εργασία μελετήθηκε το φαινόμενο της ετερογενούς φωτοκατάλυσης ως μέσο απολύμανσης παθογόνων μικροοργανισμών αξιοποιώντας την ηλιακή ακτινοβολία. Οι μικροοργανισμοί που  εξετάσθηκαν ήταν τα παθογόνα βακτήρια Pseudomonas aeruginosa και Klebsiella pneumonia, ενώ ο καταλύτης που χρησιμοποιήθηκε ήταν το Διοξειδίου του Τιτανίου TiO2. Έγιναν έξι σειρές πειραμάτων με την κάθε σειρά να περιλαμβάνει δύο πειράματα, ένα για τον κάθε μικροοργανισμό.  Αρχικά  τα πειράματα έγιναν σε αποστειρωμένες συνθήκες και διαφορετικές συγκεντρώσεις μικροοργανισμών και φωτοκαταλύτη. Παρόλο που η ηλιακή ακτινοβολία δεν ήταν πάντα σε υψηλά επίπεδα τα αποτελέσματα ήταν εκπληκτικά με το μικροβιακό φορτίο να εκμηδενίζεται σε όλα τα πειράματα. Η ετερογενής φωτοκατάληση, αν και αντιμετωπίζοντας κάποιες δυσκολίες, έδειξε επίσης την απολυμαντική της δράση για τους υπό εξέταση μικροοργανισμούς και σε μη αποστειρωμένες συνθήκες όταν χρησιμοποιήθηκε νερό βρύσης και λύμα προερχόμενο από δευτεροβάθμια δεξαμενή καθίζησης ως υδάτινη μήτρα. Εξαιτίας της μεταβαλλόμενης ηλιακής ακτινοβολίας από πείραμα σε πείραμα δεν βγήκε κάποιο ασφαλές πόρισμα για το ποιός μικροοργανισμός είναι πιο ανθεκτικός στην φωτοκατάλυση, πέραν του ότι και οι δύο είναι  αρκετά πολύπλοκοι είτε στον πολλαπλασιασμό είτε στην θανάτωση τους και χρήζουν ιδιαίτερης εργαστηριακής μεταχείρισης. Από την άλλη μεριά η φωτοκατάλυση έδειξε να μπορεί να δώσει σπουδαία αποτελέσματα για διάφορες τιμές της ηλιακής ακτινοβολίας ακόμα και μέσα στην Νοέμβριο. Η θετική άποψη που αναπτύσσεται για την ετερογενή φωτοκατάλυση μέσα από την παρούσα διπλωματική δεν φαίνεται δυστυχώς να είναι και καθολική καθώς πολλοί επιστήμονες κρατούν επιφυλακτική ακόμα στάση απέναντι στην αξιοπιστία της μεθόδου και στην ικανότητα της να εφαρμοστεί επιτυχώς σε απολυμαντικά έργα μεγάλης κλίμακας. Παράλληλα με τα πειράματα της φωτοκατάλυσης, έγινε μια μικρή μεμονωμένη έρευνα για τα parabens και συγκεκριμένα του methylparaben, ενός συντηρητικού, η οποία μέσα από δύο πειράματα που έγιαναν έδειξε ότι το methylparaben δεν είναι τοξικό για την P.aeruginosa και την K.pneumonia.

description: We study the topologically protected Majorana zero modes induced by lattice dislocations in chiral topological superconductors. Dislocations provide a new way to realize Majorana zero modes at zero magnetic field. In particular, we study several different types of dislocations in the candidate material ${\rm Sr_2RuO_4}.$ We also discuss the properties of linked dislocation lines and linked dislocation and flux lines. Various experimental consequences are predicted which provide a new approach to determine whether nature of the superconducting phase of ${\rm Sr_2RuO_4}.$

description: In this paper we present InterHorn, a solver for recursion-free Horn clauses. The main application domain of InterHorn lies in solving interpolation problems arising in software verification. We show how a range of interpolation problems, including path, transition, nested, state/transition and well-founded interpolation can be handled directly by InterHorn. By detailing these interpolation problems and their Horn clause representations, we hope to encourage the emergence of a common back-end interpolation interface useful for diverse verification tools.

description: Knowing a sequence of moments of a given, infinitely supported, distribution we obtain quickly: coefficients of the power series expansion of monic polynomials $\left\{ p_{n}\right\} _{n\geq 0}$ that are orthogonal with respect to this distribution, coefficients of expansion of $x^{n}$ in the series of $p_{j},$ $j\leq n$, two sequences of coefficients of the 3-term recurrence of the family of $\left\{ p_{n}\right\} _{n\geq 0}$, the so called "linearization coefficients" i.e. coefficients of expansion of $% p_{n}p_{m}$ in the series of $p_{j},$ $j\leq m+n.$\newline Conversely, assuming knowledge of the two sequences of coefficients of the 3-term recurrence of a given family of orthogonal polynomials $\left\{ p_{n}\right\} _{n\geq 0},$ we express with their help: coefficients of the power series expansion of $p_{n}$, coefficients of expansion of $x^{n}$ in the series of $p_{j},$ $j\leq n,$ moments of the distribution that makes polynomials $\left\{ p_{n}\right\} _{n\geq 0}$ orthogonal. \newline Further having two different families of orthogonal polynomials $\left\{ p_{n}\right\} _{n\geq 0}$ and $\left\{ q_{n}\right\} _{n\geq 0}$ and knowing for each of them sequences of the 3-term recurrences, we give sequence of the so called "connection coefficients" between these two families of polynomials. That is coefficients of the expansions of $p_{n}$ in the series of $q_{j},$ $j\leq n.$\newline We are able to do all this due to special approach in which we treat vector of orthogonal polynomials $\left\{ p_{j}\left( x)\right) \right\} _{j=0}^{n}$ as a linear transformation of the vector $\left\{ x^{j}\right\} _{j=0}^{n}$ by some lower triangular $(n+1)\times (n+1)$ matrix $\mathbf{Π}_{n}.$
