description: CARD (comfort, ask, relax, distract) is a vaccine delivery framework that includes interventions to improve the patient’s experience. CARD has not been previously implemented in long-term care (LTC) settings. This study evaluated drivers to implementation for COVID-19 vaccinations in an LTC facility. Postimplementation interpretive evaluation including qualitative interviews and quantitative surveys with eight participants. The Consolidated Framework for Implementation Research (CFIR) was used for analysis. Adverse reactions to vaccinations and CARD interventions, including local reactogenicity and systemic reactions, were abstracted from medical charts of residents. Eight CFIR constructs emerged. Staff perceived CARD was complex because it added steps to vaccination delivery. Motivated to meet residents’ needs, a receptive implementation climate of support among staff led to using strategies within CARD, such as administering topical anesthetics and omitting alcohol skin antisepsis prior to injections. Having an effective network like the residents council positively influenced implementation by allowing residents to voice their opinions. Facilitators to implementation included staff knowledge and beliefs and staff’s commitment to their organization, which was focused on person-centered care. Barriers included lack of available resources (inadequate staffing), insufficient communication between management and staff and lack of awareness of CARD, and external policies not aligned with CARD. Chart reviews conducted for 93 vaccinated residents corroborated perceptions of vaccination and CARD intervention safety, revealing a low rate of local and systemic adverse reactions and no cases of skin infection. We identified positive and negative implementation drivers. Future research is recommended to expand the strategies employed and involve residents more directly.

description: Η ραχοκοκαλιά αυτής της εργασίας, βασίζεται στη διαχείριση της σχέσης παρελθόντος-παρόντος. Προβάλλει τις ανησυχίες και θέτει ερωτήματα για το πώς ο κάθε τόπος, η κάθε περιοχή, είναι αναγκαίο να διατηρεί την κουλτούρα και τα ιδιαίτερα πολιτιστικά χαρακτηριστικά που την διακρίνουν, ενώ παράλληλα ως κομμάτι μιας παγκόσμιας πολιτισμικής κοινότητας οφείλει να έχει έναν ενεργητικό ρόλο, παρακολουθώντας και συμμετέχοντας στις εξελίξεις. Θίγονται επομένως θέματα, που στρέφονται γύρω από τον τόπο, το τοπίο, την παράδοση, τη διατήρηση της ταυτότητας κάθε τόπου και την αποτύπωση ενός ζωντανού παρελθόντος στο παρόν.
Μέσα από την κατανόηση και την ανάλυση λοιπόν, αυτών των εννοιών και σχέσεων, επιχειρείται ο εντοπισμός των σταθερών όπου μέσω της πολιτιστικής τους αξίας, της αισθητικής τους ποιότητας, καθώς και του περιβαλλοντικού και εθνογραφικού τους πλούτου, θα επιχειρηθεί η ανάγνωση της περιοχής της Ανδαλουσίας στο επίπεδο της ανώνυμης και λόγιας αρχιτεκτονικής. Η περιοχή αυτή παρουσιάζει ένα ιδιαίτερο ενδιαφέρον όσον αφορά την ποικιλία μορφών και σχέσεων που αναπτύχθηκαν στην αρχιτεκτονική, καθώς αποτελεί σε πρώτη ανάγνωση τόπο αντικρουόμενων επιρροών. Προκειμένου λοιπόν να διαμορφωθεί μια όσον το δυνατόν πιο σφαιρική εικόνα γύρω από την αρχιτεκτονική που αναπτύχθηκε στη συγκεκριμένη περιοχή, η μελέτη θα οργανωθεί με αναφορές σε δύο κεντρικούς άξονες: ως προς τα κύρια χαρακτηριστικά που παρουσιάζει σε επίπεδο τύπων, αναλύοντας τη σημασία του αίθριου και τη σχέση που αναπτύσσεται με το δημόσιο χώρο και ως προς  την αισθαντικότητα και τη διαχείριση των στοιχείων διακόσμησης.  Γίνεται αντιληπτή επομένως η λαϊκή αρχιτεκτονική που χαρακτηρίζει αυτόν τον τόπο και του αποδίδει έναν ιδιαίτερο χαρακτήρα, χωρίς ωστόσο να σημαίνει ότι μένει εγκλωβισμένη στο δικό της παρελθόν.
Ως πρόσμειξη διαφορετικών πολιτισμών και κοινωνικών δομών , η Ανδαλουσία έχει καταφέρει να αποκτήσει μια ισχυρή ταυτότητα στο πέρασμα των χρόνων, η οποία είναι σύγχρονη και διατηρείται ζωντανή, χωρίς ωστόσο να έχει αποβάλλει όλα αυτά τα πολιτιστικά χαρακτηριστικά του παρελθόντος , στα οποία οφείλει την ύπαρξή της. Αναζητούνται επομένως, στο σύγχρονο αποτύπωμά της, μέσω συγκεκριμένων  παραδειγμάτων κτιρίων, τα στοιχεία αυτά που εγγράφουν καλύτερα την παραδοσιακή κουλτούρα και που συγχρόνως ακολουθούν τα πρότυπα της σύγχρονης αρχιτεκτονικής.

description: We introduce a protocol with a reconfigurable filter system to create non-overlapping single loops in the smart power grid for the realization of the Kirchhoff-Law-Johnson-(like)-Noise secure key distribution system. The protocol is valid for one-dimensional radial networks (chain-like power line) which are typical of the electricity distribution network between the utility and the customer. The speed of the protocol (the number of steps needed) versus grid size is analyzed. When properly generalized, such a system has the potential to achieve unconditionally secure key distribution over the smart power grid of arbitrary geometrical dimensions.

The proof follows from Lichnerowicz type theorems for two horizon Dirac operators, the field equations and Bianchi identities, and the vanishing of the index of a Dirac operator on the 9-dimensional horizon sections. As a consequence of this, we also prove that all M-horizons with non-vanishing fluxes admit a sl(2,R) subalgebra of symmetries.

Statistics of Conductances and Subleading Corrections to Scaling near the Integer Quantum Hall Plateau Transition

description: We study the critical behavior near the integer quantum Hall plateau transition by focusing on the multifractal (MF) exponents $X_q$ describing the scaling of the disorder-average moments of the point contact conductance $T$ between two points of the sample, within the Chalker-Coddington network model. Past analytical work has related the exponents $X_q$ to the MF exponents $Δ_q$ of the local density of states (LDOS). To verify this relation, we numerically determine the exponents $X_q$ with high accuracy. We thereby provide, at the same time, independent numerical results for the MF exponents $Δ_q$ for the LDOS. The presence of subleading corrections to scaling makes such determination directly from scaling of the moments of $T$ virtually impossible. We overcome this difficulty by using two recent advances. First, we construct pure scaling operators for the moments of $T$ which have precisely the same leading scaling behavior, but no subleading contributions. Secondly, we take into account corrections to scaling from irrelevant (in the renormalization group sense) scaling fields by employing a numerical technique ("stability map") recently developed by us. We thereby numerically confirm the relation between the two sets of exponents, $X_q$ (point contact conductances) and $Δ_q$ (LDOS), and also determine the leading irrelevant (corrections to scaling) exponent $y$ as well as other subleading exponents. Our results suggest a way to access multifractality in an experimental setting.

description: In a recent, modified double-pinhole diffraction experiment the existence of an interference pattern was established indirectly along with a near-perfect imaging of the double pinhole. Our theoretical analysis shows that the experiment constitutes a preparation of a quantum state that is, to a good approximation, a joint eigenstate of commuting functions of position and momentum. Gaining information about the momentum distribution by means of the particular experimental setup is thus possible with negligible impact on the position distribution. Furthermore, we construct explicitly a class of states simultaneously localised on periodic sets in position and momentum space, which are therefore eigenstates of the observables being measured jointly (to a good approximation) in multi-slit interferometry. Finally, we show that with an appropriate change of settings the experiment demonstrates the mutual disturbance of position and momentum measurements.

The Fiber Walk: A Model of Tip-Driven Growth with Lateral Expansion

description: Tip-driven growth processes underlie the development of many plants. To date, tip-driven growth processes have been modelled as an elongating path or series of segments without taking into account lateral expansion during elongation. Instead, models of growth often introduce an explicit thickness by expanding the area around the completed elongated path. Modelling expansion in this way can lead to contradictions in the physical plausibility of the resulting surface and to uncertainty about how the object reached certain regions of space. Here, we introduce "fiber walks" as a self-avoiding random walk model for tip-driven growth processes that includes lateral expansion. In 2D, the fiber walk takes place on a square lattice and the space occupied by the fiber is modelled as a lateral contraction of the lattice. This contraction influences the possible follow-up steps of the fiber walk. The boundary of the area consumed by the contraction is derived as the dual of the lattice faces adjacent to the fiber. We show that fiber walks generate fibers that have well-defined curvatures, enable the identification of the process underlying the occupancy of physical space. Hence, fiber walks provide a base from which to model both the extension and expansion of physical biological objects with finite thickness.

description: This paper studies a multi-user multiple-input single-output (MISO) downlink system for simultaneous wireless information and power transfer (SWIPT), in which a set of single-antenna mobile stations (MSs) receive information and energy simultaneously via power splitting (PS) from the signal sent by a multi-antenna base station (BS). We aim to minimize the total transmission power at BS by jointly designing transmit beamforming vectors and receive PS ratios for all MSs under their given signal-to-interference-plus-noise ratio (SINR) constraints for information decoding and harvested power constraints for energy harvesting. First, we derive the sufficient and necessary condition for the feasibility of our formulated problem. Next, we solve this non-convex problem by applying the technique of semidefinite relaxation (SDR). We prove that SDR is indeed tight for our problem and thus achieves its global optimum. Finally, we propose two suboptimal solutions of lower complexity than the optimal solution based on the principle of separating the optimization of transmit beamforming and receive PS, where the zero-forcing (ZF) and the SINR-optimal based transmit beamforming schemes are applied, respectively.

A Deep Learning First Approach to Remaining Useful Lifetime Prediction of Filtration System With Improved Response to Changing Operational Parameters Using Parameterized Fully-connected Layer

description: For the remaining useful lifetime prediction, apart from the normal sensor data which is updated regularly, there are also operational parameters, which do not change during a cycle of operation. Different sets of parameters result in essentially different, but relevant systems and thus require the adaptation from the statistical model for better prediction. We noticed that neural networks could easily overfit into one set of operational parameters and demonstrate constant bias in the prediction for other sets (underfitting). An aspect of major contribution from our work is the use of Parameterized Fully-Connected Layer (PFL). The PFL builds the parameter dependency right into each layer, in this way the parameters act as ”meta-inputs” which adapt the model of neural network models to the different operating conditions. In another aspect of contribution, our work demonstrated that, instead of using feature engineering, convolutional layers could be used to automatically learn the features which are relevant for the prediction. In this way, the deep learning architecture could be reused for different problems or systems. We conduct experiments on the filtration system datasets provided by the Data Challenge 2020 and received results that compare favorably to the prize winners.

description: In the three-dimensional topological insulator (TI), the physics of doped semiconductors exists literally side-by-side with the physics of ultra-relativistic Dirac fermions. This unusual pairing creates a novel playground for studying the interplay between disorder and electronic transport. In this mini-review we focus on the disorder caused by the three-dimensionally distributed charged impurities that are ubiquitous in TIs, and we outline the effects it has on both the bulk and surface transport in TIs. We present self-consistent theories for Coulomb screening both in the bulk and at the surface, discuss the magnitude of the disorder potential in each case, and present results for the conductivity. In the bulk, where the band gap leads to thermally activated transport, we show how disorder leads to a smaller-than-expected activation energy that gives way to VRH at low temperatures. We confirm this enhanced conductivity with numerical simulations that also allow us to explore different degrees of impurity compensation. For the surface, where the TI has gapless Dirac modes, we present a theory of disorder and screening of deep impurities, and we calculate the corresponding zero-temperature conductivity. We also comment on the growth of the disorder potential as one moves from the surface of the TI into the bulk. Finally, we discuss how the presence of a gap at the Dirac point, introduced by some source of time-reversal symmetry breaking, affects the disorder potential at the surface and the mid-gap density of states.

description: Optical networks are vulnerable to physical layer attacks; wiretappers can improperly receive messages intended for legitimate recipients. Our work considers an aspect of this security problem within the domain of multimode fiber (MMF) transmission. MMF transmission can be modeled via a broadcast channel in which both the legitimate receiver's and wiretapper's channels are multiple-input-multiple-output complex Gaussian channels. Source-channel coding analyses based on the use of distortion as the metric for secrecy are developed. Alice has a source sequence to be encoded and transmitted over this broadcast channel so that the legitimate user Bob can reliably decode while forcing the distortion of wiretapper, or eavesdropper, Eve's estimate as high as possible. Tradeoffs between transmission rate and distortion under two extreme scenarios are examined: the best case where Eve has only her channel output and the worst case where she also knows the past realization of the source. It is shown that under the best case, an operationally separate source-channel coding scheme guarantees maximum distortion at the same rate as needed for reliable transmission. Theoretical bounds are given, and particularized for MMF. Numerical results showing the rate distortion tradeoff are presented and compared with corresponding results for the perfect secrecy case.

description: A previously unknown instability creates space-filling lattices of 3D vortices in linearly-stable, rotating, stratified shear flows. The instability starts from an easily-excited critical layer. The layer intensifies by drawing energy from the background shear and rolls-up into vortices that excite new critical layers and vortices. The vortices self-similarly replicate to create lattices of turbulent vortices. The vortices persist for all time. This self-replication occurs in stratified Couette flows and in the dead zones of protoplanetary disks where it can de-stabilize Keplerian flows.

description: Existence of a protected surface state described by a massless Dirac equation is a defining property of the topological insulator. Though this statement can be explicitly verified on an idealized flat surface, it remains to be addressed to what extent it could be general. On a curved surface, the surface Dirac equation is modified by the spin connection terms. Here, in the light of the differential geometry, we give a general framework for constructing the surface Dirac equation starting from the Hamiltonian for bulk topological insulators. The obtained unified description clarifies the physical meaning of the spin connection.

description: In this paper we define an efficient implementation for the family of low-rank energy-conserving Runge-Kutta methods named Hamiltonian Boundary Value Methods (HBVMs), recently defined in the last years. The proposed implementation relies on the particular structure of the Butcher matrix defining such methods, for which we can derive an efficient splitting procedure. The very same procedure turns out to be automatically suited for the efficient implementation of Gauss-Legendre collocation methods, since these methods are a special instance of HBVMs. The linear convergence analysis of the splitting procedure exhibits excellent properties, which are confirmed by a few numerical tests.

description: The tails of the distribution of a mean zero, variance $σ^2$ random variable $Y$ satisfy concentration of measure inequalities of the form $\mathbb{P}(Y \ge t) \le \exp(-B(t))$ for $$ B(t)=\frac{t^2}{2( σ^2 + ct)} \quad \mbox{for $t \ge 0$, and} \quad B(t)=\frac{t}{c}\left( \log t - \log \log t - \frac{σ^2}{c}\right) \quad \mbox{for $t>e$} $$ whenever there exists a zero biased coupling of $Y$ bounded by $c$, under suitable conditions on the existence of the moment generating function of $Y$. These inequalities apply in cases where $Y$ is not a function of independent variables, such as for the Hoeffding statistic $Y=\sum_{i=1}^n a_{iπ(i)}$ where $A=(a_{ij})_{1 \le i,j \le n} \in \mathbb{R}^{n \times n}$ and the permutation $π$ has the uniform distribution over the symmetric group, and when its distribution is constant on cycle type.

description: A possible effect of direct CP violation in D->K0Spipi decay on the gamma measurement from B->DK, D->K0Spi+pi- Dalitz plot analysis is considered. Systematic uncertainty of gamma coming from the current limits on direct CP violation in D->K0Spi+pi- is estimated, and a modified model-independent procedure of B->DK, D->K0Spi+pi- Dalitz plot analysis is proposed that gives an unbiased gamma measurement even in presence of direct CP violation in charm decays. The technique is applicable to other three-body D decays such as D->K0SK+K-, D->pi+pi-pi0, etc.

description: We point out that the mixed-event method for two-particle acceptance correction, widely used in particle correlation measurements at RHIC and LHC, is wrong in cases where the single particle pseudorapidity distribution is significantly nonuniform. The correct acceptance should be the convolution of two single-particle efficiency$\times$acceptance functions. The error of the mixed-event method, which guarantees a uniform $Δη$ two-particle combinatorial density, is, however, small in correlation analyses where the two particles are integrated over an extended pseudorapidity $η$ range. With one particle fixed in $η$ and the right acceptance correction, the background-subtracted correlated pair density may reveal not only a short-range but also a long-range $Δη$ dependence. This has important physics implication, and may provide crucial information to disentangle physics mechanisms for the recently observed long-range ridge correlation in asymmetric proton-lead collisions at the LHC.

description: Anaerobic digestion is a key technology for the treatment of organic waste streams and is used worldwide to treat domestic wastewater for the production of biogas. Alongside biogas, digestate is produced after anaerobic digestion process which is rich in organic matter, nutrients such as phosphorus, nitrogen, potassium and other micronutrients and therefore have great potential to be used as organic fertilizer. Production of biogas and recovery of nutrients from wastewater can promote the circular economy, reduce waste water treatment environmental footprint and minimize the anthropogenic inflow of nitrogen and phosphorus into the environment.

description: 	Η παρούσα ερευνητική εργασία αναλύει την ιστορική και πολεοδομική μελέτη της πόλης των Χανίων, από τα πρώτα κιόλας ευρήματα οικισμού στο λόφο του Καστελίου και την ανάπτυξη οικισμών γύρω από αυτή. Παρουσιάζονται χρονολογικά οι νέες οικιστικές περιοχές που δημιουργούνται μετά το 1946 μ.Χ.. Αναφέρονται οι τρόποι επέκτασης κάθε περιοχής, καθώς καθεμία απ' αυτές ολοκληρώνεται σταδιακά. Μεγαλύτερη ανάλυση γίνεται στους λόγους επέκτασης τους, όπως: α)στεγαστικά προγράμματα, στα οποία βασίζονται οικιστικές αναπτύξεις οργανωμένης δόμησης, β)οργανωμένη δόμηση κοινωνικών κατοικιών για τους πρόσφυγες και γ)τροποποιήσεις και επεκτάσεις σχεδίων με καθορισμό όρων και περιορισμών δόμησης οικοπέδων. Στη συνέχεια, σε κάθε περιοχή αποτυπώνεται πρόταση για διαμόρφωση των χρήσεων γης και εξετάζονται οι προτεινόμενοι και οι πραγματοποιούμενοι όροι δόμησης. Βάση δίνεται στη σχέση των οικισμών με την πόλη και κατ' επέκταση στη σχέση και σύνδεση των οικισμών μεταξύ τους, μέσω χαράξεων δρόμων και πεζοδρόμων. Στη συνέχεια, εξετάζεται η σχέση μεταξύ των τύπων των κατοικιών και η σχέση ιδιωτικού, ημιδιωτικού και δημόσιου χώρου κάθε τύπου κατοικίας. Τέλος, συγκρίνονται τα εγκεκριμένα σχέδια επεκτάσεων κάθε οικισμού με τα ισχύοντα ρυμοτομικά σχέδια, οι χρήσεις γης που προτάθηκαν σε σχέση με τις ισχύουσες, οι όροι και περιορισμοί δόμησης και η σχέση δρόμων, πεζοδρόμων και χώρων στάθμευσης, με βάση την υπάρχουσα κατάσταση, στοχεύοντας στη σύγκριση της διαμορφωμένης κατάστασης με τις αρχικές προθέσεις του σχεδιασμού.

description: Συνδυάζοντας την θεωρία του game design με τα τρέχοντα επιτεύγματα στην τεχνολογία του virtual reality, η συγκεκριμένη διπλωματική εργασία ασχολείται με τον σχεδιασμό ενός πάρκου διασκέδασης στην περιοχή του Αγίου Ιωάννη Ρέντη, στην Αθήνα. Το βασικό εφαλτήριο σχεδιασμού έχει διαμορφωθεί από δύο παράγοντες. Ο πρώτος έχει να κάνει με την σχέση εικονικού και πραγματικού χώρου όπως αυτή έχει διαμορφωθεί μέσα από τις τρέχουσες τεχνολογικές εξελίξεις. Ο δεύτερος παράγοντας εστιάζει στους χρήστες – παίκτες που θα επισκεφθούν το πάρκο και στις κατηγορίες που αυτοί χωρίζονται. Ο συνδυασμός των δύο παραγόντων αποδίδει στον χώρο ένα τοπιακό πάρκο που τοποθετείται στο ενδιάμεσο πεδίο της αρχιτεκτονικής και του game design.

description: This paper is concerned with the recognition of approximate graph products with respect to the Cartesian product. Most graphs are prime, although they can have a rich product-like structure. The proposed algorithms are based on a local approach that covers a graph by small subgraphs, so-called partial star products, and then utilizes this information to derive the global factors and an embedding of the graph under investigation into Cartesian product graphs.

description: Ο χώρος και το φως αποτελούν δυο αλληλένδετα  και άρρηκτα συνδεδεμένα στοιχεία στην αρχιτεκτονική σύνθεση. Αδιαμφισβήτητη είναι η συνεχής αλληλεπίδραση ανάμεσα στον άνθρωπο και στο χώρο καθώς επίσης και η απόδοση ποιότητας και ατμόσφαιρας στο χώρο μέσω του φωτός.  Έτσι το φως δύναται να μεταμορφώνει δραματικά την ατμόσφαιρα κάθε εσωτερικού και εξωτερικού χώρου , με το πέρασμα του χρόνου, τη σκιά και τη διαφάνεια, τα χρωματικά φαινόμενα, την υφή, τα υλικά και τις λεπτομέρειες, δηλαδή να δημιουργεί ποιοτικές χωρικές αντιλήψεις και να συμβάλλει στην ανάπτυξη αισθήσεων, σκέψεων και συναισθημάτων.
Το φως, πέρα από την έννοια του φυσικού φωτός, χρησιμοποιείται επίσης για την υποβολή συμβολισμών ή νοημάτων, αποτελώντας κατά αυτόν τον τρόπο φορέα πνευματικότητας, ιερότητας και δυναμικής της θρησκευτικής εμπειρίας. Ερμηνεύεται ως κάτι θεϊκό, αόρατο και άυλο στις περισσότερες θρησκείες. Παρά το γεγονός ότι το θεϊκό και το ορατό φως αποτελούν δύο διαφορετικές έννοιες, πολυάριθμοι αρχιτέκτονες χρησιμοποιούν το φυσικό φως με διάφορες τεχνικές σε ιερούς χώρους, ώστε να αποδώσουν μια διαφορετική ατμόσφαιρα, να προκαλέσουν δέος σεβασμό και πνευματική κατάνυξη.
Στην παρούσα εργασία, θα μελετηθεί η απόδοση ατμόσφαιρας στο χώρο μέσω του χειρισμού του φωτός ∙ και πιο συγκεκριμένα θα αναλυθούν τρεις εκκλησίες του 20ου αιώνα , η Notre Dame du haut του Le Corbusier, η εκκλησία του φωτός του Tadao Ando και το παρεκκλήσι του Άγιου Ιγνάτιου του Steven Holl, ως προς την ατμόσφαιρά τους και την συνολική αντιμετώπισή τους έναντι του φυσικού φωτός. Τα εν λόγω κτήρια, φαινομενικά ανόμοια, ερευνώνται με κοινή συνιστώσα την απόδοση ιερότητας και ατμόσφαιρας στο χώρο ανεξάρτητα από τη θρησκευτική τους χρήση, μελετώνται ως ιεροί χώροι και όχι απαραίτητα θρησκευτικοί.  Μπορεί λοιπόν ένας χώρος να είναι ιερός χωρίς να είναι θρησκευτικός;

description: Governing equations of dissipative generalized solid mechanics are derived by thermodynamic methods in the Piola-Kirchhoff framework using the Liu procedure. The isotropic small strain case is investigated in more detail. The connection to the Ginzburg-Landau type evolution, dual internal variables, and a thermodynamic generalization of the standard linear solid model of rheology is demonstrated. Specific examples are chosen to emphasize experimental confirmations and predictions beyond less general approaches.

description: This review aims to advance our knowledge from previous works by calling into question; what personal and environmental resources are found to contribute to ‘PERMA’ wellbeing outcomes in early career employees? Specifically, which personal and environmental resources have been cited as important contributors to early careers’ wellbeing? And, what positive outcomes of wellbeing have these resources been found to contribute to? The hope is that this review will add an additional layer of conceptual clarity to our current understanding that will in turn streamline and afford due direction for future empirical research in the remit of early career development. It is thought by the researcher that individuals well supported both internally and externally to build a sustainable start should foster wellbeing outcomes that subsequently translates into their later career ‘success’ (achieving a desired or favourable outcome), personal and economic ‘growth’ (a process of progressive development) (Merriam-Webster, n.d.). To the researcher’s knowledge, this is the first systematic review to explore the contribution of specific personal and environmental resources to wellbeing outcomes in the context of early career stages.

Επιλέξαμε επομένως να δημιουργήσουμε ένα πάρκο που θα περιλαμβάνει ποικίλες χρήσεις (όπως αθλητισμός, πολιτισμός, οργανωμένο συγκρότημα κατοίκησης, παιδική χαρά, καλλιέργειες, skate park κ.α.) αλλά και διαφορετικές χωρικές ποιότητες όπως μικρά πλατώματα, μεγαλύτερες πλατείες, μονοπάτια, λόφους, χώρους πρασίνου με έντονη ή ήπια βλάστηση, ούτως ώστε η περιοχή μελέτης να λειτουργεί ως πόλος έλξης για τους πολίτες όλες τις ώρες της ημέρας αλλά και όλους τους μήνες του χρόνου. Δημιουργούνται βαθμίδες με στόχο την επίλυση της υψομετρικής διαφοράς στη περιοχή και τη συνεχή οπτική επαφή και άμεση πρόσβαση σε όλα τα σημεία του πάρκου. Σημαντικό στοιχείο της πρότασης αποτελεί η εισαγωγή του υδάτινου στοιχείου καθώς και ο σχεδιασμός κτιρίου πολιτισμικής κυρίως χρήσης που φαίνεται να βγαίνει από τον βράχο, με βατό δώμα ως συνέχεια της βασικής περιπατητικής πορείας της πρότασης. Τέλος, μεριμνούμε για την καλύτερη δυνατή κυκλοφορία στην περιοχή, από και προς αυτήν με τους χώρους στάθμευσης των οχημάτων να προβλέπονται στις δύο εισόδους του πάρκου με στόχο την αποφόρτιση του από αυτά.

description: Using the LAMP model for nuclear quark structure, we calculate the binding energy and quark structure of a $B$ meson merging with a $D$ meson. The larger-than-nucleon masses of the two heavy quarks allow for a more reliable application of the Born-Oppenheimer-like approximation of the LAMP. With the absence of quark-level Pauli Exclusion Principle repulsive effects, the appearance of a bound state is unsurprising. Our variational calculation shows that the molecular, deuteron-like state structure changes rather abruptly, as the separation between the two mesons decreases, at a separation of about 0.45 fm, into a four-quark bound state, although one maintaining an internal structure rather than that of a four-quark bag. Unlike the deuteron, pion exchange does not provide any contribution to the $\approx 150$ MeV binding.

description: We study a spin dynamics of two magnetic Chromium atoms trapped in a single site of a deep optical lattice in a resonant magnetic field. Dipole-dipole interactions couple spin degrees of freedom of the two particles to their motion in the site. The motion is quantized, therefore a trap geometry combined with two-body contact s-wave interactions influence a spin dynamics through the energy spectrum of the two atom system. Anharmonicity and anisotropy of the site results in a `fine' structure of two body eigenenergies. The structure can be easily resolved by a weak magnetic dipole-dipole interactions. As an example we examine the effect of anharmonicity and anisotropy of the binding potential on the Einstein-de Haas effect. We show that the weak dipolar interactions provide a perfect tool for a precision spectroscopy of the energy spectrum of the interacting few particle system.
