description: Future multi-functional hybrid devices might combine switchable molecules and 2D material-based devices. Spin-crossover compounds are of particular interest in this context since they exhibit bistability and memory effects at room temperature while responding to numerous external stimuli. Atomically-thin 2D materials such as graphene attract a lot of attention for their fascinating electrical, optical, and mechanical properties, but also for their reliability for room-temperature operations. Here, we demonstrate that thermally-induced spin-state switching of spin-crossover nanoparticle thin films can be monitored through the electrical transport properties of graphene lying underneath the films. Model calculations indicate that the charge carrier scattering mechanism in graphene is sensitive to the spin-state dependence of the relative dielectric constants of the spin-crossover nanoparticles. This graphene sensor approach can be applied to a wide class of (molecular) systems with tunable electronic polarizabilities.

description: The significance of the magnitude of Prandtl number of a fluid in the propagation direction of induced convection rolls is elucidated. Specifically, we report on the physical mechanism to account for the formation and orientation of previously unexplored supra-wavelength periodic surface structures in dielectrics, following melting and subsequent capillary effects induced upon irradiation with ultrashort laser pulses. Counterintuitively, it is found that such structures exhibit periodicities, which are markedly, even multiple times, higher than the laser excitation wavelength. It turns out that the extent to which the hydrothermal waves relax depends upon the laser beam energy, produced electron densities upon excitation with femtosecond pulsed lasers, magnitude of the induced initial local roll disturbances and the magnitude of the Prandtl number with direct consequences on the orientation and size of the induced structures. It is envisaged that this elucidation may be useful for the interpretation of similar, albeit large-scale periodic or quasi-periodic structures formed in other natural systems due to thermal gradients, while it can also be of great importance for potential applications in biomimetics.

description: Multiple Importance Sampling (MIS) methods approximate moments of complicated distributions by drawing samples from a set of proposal distributions. Several ways to compute the importance weights assigned to each sample have been recently proposed, with the so-called deterministic mixture (DM) weights providing the best performance in terms of variance, at the expense of an increase in the computational cost. A recent work has shown that it is possible to achieve a trade-off between variance reduction and computational effort by performing an a priori random clustering of the proposals (partial DM algorithm). In this paper, we propose a novel "heretical" MIS framework, where the clustering is performed a posteriori with the goal of reducing the variance of the importance sampling weights. This approach yields biased estimators with a potentially large reduction in variance. Numerical examples show that heretical MIS estimators can outperform, in terms of mean squared error (MSE), both the standard and the partial MIS estimators, achieving a performance close to that of DM with less computational cost.

Interrogating the display case: communicating prehistory within Museum Displays
Creators: name: McDowall, Felicity
Publisher: name: Journal of Mediterranean Earth Sciences

description: Prehistory museum displays represent a vital medium through which the complex narratives of early human history are communicated to the public. These narratives, however, are not neutral and are subject to a variety of factors such as: institutional mission, curatorial preferences, funding and history of collections. This paper seeks to understand what narratives museums currently convey by providing an evaluation of contemporary prehistory displays in England. The evaluation operates at both a macro and micro-scale to facilitate the interpretation of broad trends influencing the presentation of prehistory, as well as capturing ‘fine-grain’ detail about how these displays influence visitor engagements. This paper is based upon a combined visual analysis of 173 prehistory displays across England and visitor-based evaluation of 300 visitors at 6 different museums: The British Museum, The Stonehenge Visitor Centre, North Lincolnshire Museum, Torquay Museum, Weston Park Museum and the Great North Museum. The combined visual and visitor-based evaluation reveals representational disparities between how early prehistoric periods are communicated compared to later prehistoric periods, and the effectiveness of interactive and audio-visuals interpretation for engaging visitors with narratives about their earliest past. How these trends relate more widely to prehistory museum displays in Europe is reflected upon in the discussion and the paper concludes with some evidence-based recommendations for effectively communicating prehistory within museum displays.

description: A new way of constructing unextendible maximally entangled basis (UMEB) from maximally entangled basis (MEB) is proposed. Consequently, it is shown that if there is an $N$-member UMEB in $\mathbb{C}^d\otimes \mathbb{C}^d$, then there exists a $(qd)^2-q(d^2-N)$-member UMEB in $\mathbb{C}^{qd}\otimes \mathbb{C}^{qd}$ for any $q\in\mathbb{N}$. This improves the results in [Phys. Rev. A 90, 034301(2014)], which shows that there exists a $(qd)^2-(d^2-N)$-member UMEB in $\mathbb{C}^{qd}\otimes \mathbb{C}^{qd}$ provided that an $N$-member UMEB exsits in $\mathbb{C}^d\otimes \mathbb{C}^d$.

description: Quantitative models of sunspot and starspot decay predict the timescale of magnetic diffusion and may yield important constraints in stellar dynamo models. Motivated by recent measurements of starspot lifetimes, we investigate the disintegration of a magnetic flux tube by nonlinear diffusion. Previous theoretical studies are extended by considering two physically motivated functional forms for the nonlinear diffusion coefficient $D$: an inverse power-law dependence $D \propto B^{-ν}$ and a step-function dependence of $D$ on the magnetic field magnitude $B$. Analytical self-similar solutions are presented for the power-law case, including solutions exhibiting "superfast" diffusion. For the step-function case, the heat-balance integral method yields approximate solutions, valid for moderately suppressed diffusion in the spot. The accuracy of the resulting solutions is confirmed numerically, using a method which provides an accurate description of long-time evolution by imposing boundary conditions at infinite distance from the spot. The new models may allow insight into differences and similarities between sunspots and starspots.

description: The middle Pleistocene site of Poggetti Vecchi (Grosseto, Italy) was excavated in 2012 when the construction of a thermal pool brought to light a stratigraphic succession with various levels of human frequentation. The data suggest that the presence of thermal water made Poggetti Vecchi a refuge area for animals and Neanderthals at the beginning of the penultimate glaciation (MIS6), when the climate was getting colder. The oldest archaeological unit (U2), dating around 171,000 years BP, consists of a palaeo-surface on which the remains of large fauna, stone and bone tools, and wooden artefacts were found. The remains of seven individuals of Palaeloxodon antiquus were found, probably belonging to a single family of elephants who died of natural causes. The most significant finds consist of fragments of digging sticks made of boxwood (Buxus sempervirens). Some of the sticks were partially blackened by fire, as a result of the working and finishing of the tools, providing the earliest evidence of the use of fire as an engineering tool. The particularity of Poggetti Vecchi environmental and archaeological context is ideal for the dissemination of many aspects to a non-specialist public, including the reconstruction of the human-environment relationship in a period of climatic emergency. Despite this, the site of Poggetti Vecchi is still waiting to find a suitable temporary or permanent location for a museum exhibition. Since physical space is increasingly difficult to find, while digital technologies are more accessible in everyone's daily life, the Istituto Italiano di Preistoria e Protostoria, as part of its research projects, wanted to promote the outreach of scientific culture through the virtual exhibition "170,000 years ago in Poggetti Vecchi. Neanderthals and Elephants in the Tuscan Maremma, the climate challenge”. Thanks to technology, with this virtual exhibition it was possible to substitute the real space with a digital reality capable of expanding the visiting experiences. One of the aims is to engage the public in the theme of the relationship between climate change and human communities since the origins of human history.

description: Long-term stability of deformable mirrors (DM) is a critical performance requirement for instruments requiring open-loop corrections. The effects of temperature changes in the DM performance are equally critical for such instruments. This paper investigates the long-term stability of three different Iris AO PTT111 DMs that were calibrated at different times ranging from 13 months to nearly 29 months prior to subsequent testing. Performance testing showed that only a small increase in positioning errors occurred from the initial calibration date to the test dates. The increases in errors ranged from as little as 1.38 nm rms after 18 months to 5.68 nm rms after 29 months. The paper also studies the effects of small temperature changes, up to 6.2°C around room temperature. For three different arrays, the errors ranged from 0.62-1.42 nm rms/°C. Removing the effects of packaging shows that errors are $\le$0.50 nm rms/°C. Finally, measured data showed that individual segments deformed $\le$0.11 nm rms/°C when heated.

title: The Image of the Nurse in a Professional Journal: A Historical Perspective
Creators: name: Crane, Dawn Louise
Publisher: name: Old Dominion University Libraries
Year: 1986

description: Authors of journal articles contribute to the image of the nurse that is projected to journal readers. The purpose of this study was to explore the image of nursing as portrayed in articles published in Nursing Outlook from 1960-1979. A descriptive study, with content analysis, was conducted using articles concerned with professionalism or nursing education published in Nursing Outlook from 1960-1979 (a time identified as negative for societal images of nursing). The educational background of the authors was noted. Findings indicated that the majority of authors projected the image of a nurse as a well-educated, independent professional; images not reflective of societal views. The number of nurse authors increased over the twenty years and there was a significant increase in the number of nurses with graduate preparation. It was concluded that authors should continue to be futuristic, establish goals for improving nursing's image, and write in conjunction with those goals.

description: We present a sample of 80 candidate strongly lensed galaxies with flux density above 100mJy at 500μm extracted from the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS), over an area of 600 square degrees. Available imaging and spectroscopic data allow us to confirm the strong lensing in 20 cases and to reject it in one case. For other 8 objects the lensing scenario is strongly supported by the presence of two sources along the same line of sight with distinct photometric redshifts. The remaining objects await more follow-up observations to confirm their nature. The lenses and the background sources have median redshifts z_L = 0.6 and z_S = 2.5, respectively, and are observed out to z_L = 1.2 and z_S = 4.2. We measure the number counts of candidate lensed galaxies at 500μm and compare them with theoretical predictions, finding a good agreement for a maximum magnification of the background sources in the range 10-20. These values are consistent with the magnification factors derived from the lens modelling of individual systems. The catalogue presented here provides sub- mm bright targets for follow-up observations aimed at exploiting gravitational lensing to study with un-precedented details the morphological and dynamical properties of dusty star forming regions in z >~ 1.5 galaxies.

description: Colourful and ever-changing: Graffiti can be considered the urban chameleon skin. At the Donaukanal (Eng. Danube Channel), Vienna's central waterway and one of the largest and most active graffiti-scapes worldwide, this metaphor applies like hardly anywhere else. Every day a multitude of graffiti is destroyed by the creation of new works. Recently, efforts have been made to mitigate this constant loss of cultural heritage along the Donaukanal by systematically documenting the graffiti, mainly using photography and photogrammetry. However, keeping track of the newly added works is very time-consuming and often like finding needles in a haystack, considering the large extent and high volatility of the monitored area. Thus, an automated graffiti change detection would significantly reduce the effort and avoid overlooking graffiti.
 This contribution outlines the main challenges in image-based change detection for cultural heritage and proposes a hybrid graffiti change detection method. The investigated method exploits and combines an established pixel-based change detection algorithm, the Iteratively Multivariate Alteration Detection, with a novel descriptor-based method. The latter relies on image features, rather than pixels as analysis unit and can robustly filter false alarms from the high-performing but noise-prone pixel-based approach. Overall, the results indicate that the proposed method can largely automate image-based change detection of graffiti-scapes. It can uncover graffiti-related changes and robustly distinguish them from other image differences such as shadows but tends to overlook small-scale graffiti, indicating the need for further fine-tuning.

description: We calculate the width of the Roper resonance at next-to-leading order in a systematic expansion of baryon chiral perturbation theory with pions, nucleons, and the delta and Roper resonances as dynamical degrees of freedom. Three unknown low-energy constants contribute up to the given order. One of them can be fixed by reproducing the empirical value for the width of the Roper decay into a pion and a nucleon. Assuming that the remaining two couplings of the Roper interaction take values equal to those of the nucleon, the result for the width of the Roper decaying into a nucleon and two pions is consistent with the experimental value.

description: For more than two centuries, solutions of differential equations have been obtained either analytically or numerically based on typically well-behaved forcing and boundary conditions for well-posed problems. We are changing this paradigm in a fundamental way by establishing an interface between probabilistic machine learning and differential equations. We develop data-driven algorithms for general linear equations using Gaussian process priors tailored to the corresponding integro-differential operators. The only observables are scarce noisy multi-fidelity data for the forcing and solution that are not required to reside on the domain boundary. The resulting predictive posterior distributions quantify uncertainty and naturally lead to adaptive solution refinement via active learning. This general framework circumvents the tyranny of numerical discretization as well as the consistency and stability issues of time-integration, and is scalable to high-dimensions.

description: Type III bursts and hard X-rays are both produced by flare energetic electron beams. The link between both emissions has been investigated in many previous studies, but no statistical studies have compared both coronal and interplanetary type III bursts with X-ray flares. Using coronal radio events above 100 MHz exclusively from type III bursts, we revisited long-standing questions: Do all coronal type III bursts have X-ray counterparts. What correlation, if any, occurs between radio and X-ray intensities. What X-ray and radio signatures above 100 MHz occur in connection with interplanetary type III bursts below 14 MHz. We analysed data from 2002 to 2011 starting with coronal type III bursts above 100 MHz. We used RHESSI X-ray data greater than 6 keV to make a list of 321 events that have associated type III bursts and X-ray flares, encompassing at least 28 percent of the initial sample of type III events. We examined the timings, intensities, associated GOES class, and any interplanetary radio signature. For our 321 events, the X-ray emission at 6 keV usually lasted longer than type III burst groups at frequencies greater than 100 MHz. A weak correlation was found between the type III radio flux at frequencies below 327 MHz and the X-ray intensity at 25-50 keV, with an absence of events at high X-ray intensity and low type III radio flux. Interplanetary type III bursts less than 14 MHz were observed for 54 percent of the events, increasing when events were observed with 25-50 keV X-rays. A stronger interplanetary association was present when 25-50 keV count rates were above 250 counts per second or 170 MHz fluxes were greater than 1000 SFU, relating to more energetic electrons above 25 keV and events where magnetic flux tubes extend into the high corona. On average type III bursts increase in flux with decreasing frequency, the rate varies from event to event.

Publisher: name: Old Dominion University Libraries
Year: 1983

description: The correlation between the nurses' attitudes toward death, as determined by the Questionnaire for Understanding the Dying Person and His Family, and the nurses' presence with a dying patient at the time of death was analyzed. The subjects were 31 registered nurses employed by eight acute care hospitals in Southeastern Virginia. The nurses were grouped into categories of flexible, moderate, and rigid attitudes toward death, relative to their scores on the questionnaire. Other variables of the nurses' age, sex, religion, strength of religious beliefs, entry level education, highest education level, years of experience, death of family members or friends, attitudes toward funerals, autopsies, and continuing education, preparation of a will, preferred funeral type, desire to notify her family if she were dying, anticipation of the patient death, time of death, and length of nurse-patient relationship were analyzed. No significant correlation was found between the nurses' attitudes toward death and their presence with the patients at the times of death. A significant correlation was determined between the nurses' attitudes toward death and their ages and religions; and between the nurses' presence with the patients at the time of death and the nurses' strength of religious beliefs, their attitudes toward autopsy and notifying their families, and their desires to study death.

description: We present a spectrally accurate method for the rapid evaluation of free-space Stokes potentials, i.e. sums involving a large number of free space Green's functions. We consider sums involving stokeslets, stresslets and rotlets that appear in boundary integral methods and potential methods for solving Stokes equations. The method combines the framework of the Spectral Ewald method for periodic problems, with a very recent approach to solving the free-space harmonic and biharmonic equations using fast Fourier transforms (FFTs) on a uniform grid. Convolution with a truncated Gaussian function is used to place point sources on a grid. With precomputation of a scalar grid quantity that does not depend on these sources, the amount of oversampling of the grids with Gaussians can be kept at a factor of two, the minimum for aperiodic convolutions by FFTs. The resulting algorithm has a computational complexity of O(N log N) for problems with N sources and targets. Comparison is made with a fast multipole method (FMM) to show that the performance of the new method is competitive.

Year: 1984

description: This study compared the levels of self-esteem of hospital staff nurses working in specialty areas versus those working in general medical-surgical areas. Fifty registered nurses employed full-time in staff positions at a large, acute-care hospital participated in the study. After indicating the area of the hospital in which they worked, the type of education they had, and the number of years of experience as a registered nurse, they then completed the Tennessee Self-Concept Scale. Scores were then compared using independent t-tests applied to the area in which the subject worked, the type of education, and the years of experience. Results indicated no significant difference in the levels of self-esteem of specialty nurses and general medical-surgical nurses. The type of education and amount of experience had no significant effect upon their levels of self-esteem.

Then, it investigates $L_p([0,T])$ approximations of sub-Gaussian random signals. Explicit truncation error upper bounds are established. The obtained rate of convergence provides a constructive algorithm for determining the sampling rate and the sample size in the truncated Whittaker-Kotel'nikov-Shannon expansions to ensure the approximation of sub-Gaussian signals with given accuracy and reliability. Some numerical examples are presented.

description: Frictional constitutive law for very slow vertical withdrawing of a thin rod from a granular bed is experimentally studied. Using a very precise creep meter, geometry-dependent granular frictional constitutive law is particularly examined. In some previous works, a dimensionless number $I=\dotγD_g/\sqrt{p/ρ_g}$ has been used to characterize granular frictional constitutive laws, where $\dotγ$, $D_g$, $p$, and $ρ_g$ are the shear strain rate, grain diameter, confining pressure, and bulk density of granular bed, respectively. It has been considered that granular frictional constitutive law expressed by $I$ is universal (almost geometry-independent) in dense flow regime. In this study, however, we find that the geometry of the system is much more crucial to characterize granular friction in a very slow withdrawing regime. Specifically, the ratio between rod and grain diameters must be an essential parameter to describe the granular frictional constitutive law. Physical meaning of the geometry-dependent constitutive law is discussed on the basis of grains-contact-number dependence of granular behavior.

description: Registered nurses in skilled nursing facilities were surveyed using the Six-Dimension Scale of Nursing Performance to determine: (1) how they rated the importance of specific nursing behaviors related to their role, (2) how they rated the frequency engaged in the same specific nursing behaviors related to their role, and (3) if there was a relationship between how they rated the specific nursing behaviors for importance and frequency. There were five subgroups of nursing behaviors: (a) leadership, (b) nursing process, (c) teaching and collaboration, (d) interpersonal relations and communication, and (e) professional development. Registered nurses rated all of the behaviors as being very important in their role; however, behaviors related to professional development were rated the highest and behaviors related to teaching and collaboration were rated the lowest for importance. Registered nurses engaged in the nursing behaviors with varying degrees of frequency. Similar to the ratings for importance, registered nurses engaged in professional development behaviors the most and teaching and collaboration behaviors the least. A significant difference was found between how registered nurses in skilled nursing facilities rated the importance of and frequency engaged in nursing behaviors related to the nursing process and teaching and collaboration.

description: $CP$ violation and branching fraction measurements in $D$ decays are interesting topics as any difference with respect to the Standard Model prediction would be an indication of new physics. With the large data sample collected by the Belle detector, which sits at the interaction point of KEKB asymmetric $e^{+} e^{-}$ collider in Japan, we present the results of searches for $CP$ violation in $D^{0}\rightarrow Vγ~(V = ϕ, \overline{K}^{*0}, ρ^{0})$ decay and the rare $D$ decay $D^{0}\rightarrow γγ$.

description: Allium ursinum L. (ramson) has been used for centuries as a food and medicinal herb. Generally, the phenology, morphology, as well as health benefits of Allium ursinum plants have been scientifically validated; however, the knowledge about geographic variation in morphological characteristics and antioxidant properties of Allium ursinum are fairly scarce. The aim of this study, therefore, was to reveal the habitat preferences of Allium ursinum in different geographical regions of the Republic of Srpska (Bosnia and Herzegovina) and to evaluate its morphological characteristics of stems, leaves and bulbs and its antioxidant properties. Morphological characteristics as well as antioxidant properties of Allium ursinum plants including total phenolics and flavonoids contents, and ferric reducing antioxidant power (FRAP) were determined. In this study, the high abundance of Allium ursinum plants was recorded at five different locations: Laktaši, Kozara, Prnjavor, Kneževo and Drinić. The results of this study revealed that Allium ursinum prefers forest habitats and that their morphological characteristics and antioxidant properties are strongly dependent on both geographical location and habitat conditions. We hereby suggest that Allium ursinum can be considered a valuable source of phenolic compounds with relevant antioxidant activity.

description: The upper critical field $H_{c2}$ of polycrystalline samples of $Ln$O$_{0.5}$F$_{0.5}$BiS$_{2}$ ($Ln$ = La, Nd) at ambient pressure (tetragonal structure) and high pressure (HP) (monoclinic structure) have been investigated via electrical resistivity measurements at various magnetic fields up to 8.5 T. The $H_{c2}$($T$) curves for all the samples show an uncharacteristic concave upward curvature at temperatures below $T_c$, which cannot be described by the conventional one-band Werthamer-Helfand-Hohenberg theory. For the LaO$_{0.5}$F$_{0.5}$BiS$_{2}$ sample under HP, as temperature is decreased, the upper critical field $H_{onset}$, estimated from the onset of the superconducting transitions, increases slowly between 4.9 and 5.8 T compared with the slope of $H_{onset}$($T$) below 4.9 T and above 5.8 T. This anomalous behavior reveals a remarkable similarity in superconductivity between LaO$_{0.5}$F$_{0.5}$BiS$_{2}$ samples measured under HP and synthesized under HP, although the crystal structures of the two samples were reported to be different. The experimental results support the idea that local atomic environment, which can be tuned by applying external pressure and can be quenched to ambient pressure via high temperature-pressure annealing, is possibly more essential to the enhancement of $T_c$ for BiS$_2$-based superconductors than the structural phase transition. On the other hand, such anomalous behavior is very subtle in the case of NdO$_{0.5}$F$_{0.5}$BiS$_{2}$ under HP, suggesting that the anisotropy of the upper critical field in the $ab$-plane and the possible lattice deformation induced by external pressure is weak. This explains why the pressure-induced enhancement of $T_c$ for NdO$_{0.5}$F$_{0.5}$BiS$_{2}$ is not as large as that for LaO$_{0.5}$F$_{0.5}$BiS$_{2}$.

description: Highly siderophile elements (HSEs) are strongly depleted in the bulk silicate Earth (BSE) but are present in near-chondritic relative abundances. The conventional explanation is that the HSEs were stripped from the mantle by the segregation of metal during core formation but were added back in near-chondritic proportions by late accretion, after core formation had ceased. Here we show that metal-silicate equilibration and segregation during Earth's core formation actually increased HSE mantle concentrations because HSE partition coefficients are relatively low at the high pressures of core formation within Earth. The pervasive exsolution and segregation of iron sulfide liquid from silicate liquid (the "Hadean matte") stripped magma oceans of HSEs during cooling and crystallization, before late accretion, and resulted in slightly suprachondritic palladium/iridium and ruthenium/iridium ratios.

description: Cyber attacks on critical infrastructure have been an issue of importance in industry over the past several years, as well as a focus of academic research. Cyber attacks of various types and magnitude have been on the rise targeted specifically at power grids. A successful attack on the power grid could result in significant impacts including grid shutdown, cascading failures, damage to the infrastructure, and potential harm to people. Power grid infrastructure are critical in nature, they enable operations for residential, commercial, industrial, and government users across critical infrastructure such as water, communication, banking, transportation, manufacturing, and more. The compromise of these operations introduces threats, which span from economic to public safety. The Advanced Metering Infrastructure (AMI) is now being rapidly deployed throughout the power grid, and is an enabling technology for smart grid. Identifying the attack surface is a necessary step in achieving cyber security in smart grids and AMI. The purpose of this paper is to quantify and examine the cyber attack surface of AMI in order to lay the foundation for mitigating approaches to AMI cyber security.
title: Factors Determining Peripheral Vascular Disease Clients' Intent to Adhere to Prescribed Behaviors

description: Motivation of clients with Peripheral Vascular Disease (PVD) to adhere to Recommended risk-reducing behaviors (RRB’s) was explored. The sample (n =30) was comprised of clients in a vascular physician group’s practice with a medical diagnosis of PVD. A nonexperimental, descriptive design was utilized to investigate how much variation in adherence to RRB’s by PVD clients could be accounted for by the client’s perceived effectiveness of a RRB and the client’s perceived difficulty in adhering to a RRB. A self-administered three part instrument, a demographic data form, and a self-administered qualitative data form were utilized to collect the data. Regression analysis revealed 26% of the variation in adherence behaviors could be significantly explained by perceived effectiveness. Perceived difficulty did not significantly contribute to the prediction equation. Future research exploring difficulty and effectiveness in other chronic illness populations and, in alternate health states with a higher degree of difficulty is recommended.

description: A new approach to construct initial data for binary systems with neutron star components is introduced. The approach is a generalization of the puncture initial data method for binary black holes based on Bowen-York solutions to the momentum constraint. As with binary black holes, the method allows setting orbital configurations with direct input from post-Newtonian approximations and involves solving only the Hamiltonian constraint. The effectiveness of the method is demonstrated with evolutions of double neutron star and black hole -- neutron star binaries in quasi-circular orbits.

description: Το βιομηχανικό συγκρότημα της «Ανώνυμης Θεσσαλικής Οινοπνευματικής Εταιρείας» (Α.Θ.Ο.Ε.), γνωστό ως «Οινόπνευμα», βρίσκεται στην συνοικία των Αγίων Αναργύρων του Βόλου, και έχει έκταση 33 στρέμματα. Ευρύτερα ο Βόλος πρόκειται για μια περιοχή με έντονη βιομηχανία και αξιόλογο ανενεργό κτιριακό δυναμικό. Συγκεκριμένα η περιοχή των Αγίων Αναργύρων θα μπορούσε να χαρακτηριστεί ως «υπνούπολη» (Schlafstadt), καθώς βρίσκεται εκτός του κέντρου του Βόλου με βασική χρήση την κατοικία και έλλειψη δημοσίων χώρων συνάθροισης. Ο στόχος της παρούσας εργασίας είναι η εκμετάλλευση του «Οινοπνεύματος», για την ενεργοποίηση της ευρύτερης γειτονιάς και τη τόνωση του δημόσιου χώρου. Αξιοποιώντας τα ανεκμετάλλευτα αστικά κενά, δημιουργείται ενας κόμβος κοινωνικής τριβής.
Την στιγμή που το 2023, σύμφωνα με έρευνα πάνω από το 75% του πληθυσμού, αδυνατεί να καταναλώσει πόρους σε ψυχαγωγία, οι ελεύθεροι δημόσιοι χώροι μοιάζουν πιο αναγκαίοι από ποτέ. Η επανάχρηση του παλιού εγκαταλελειμμένο κτηριακού συγκροτήματος, σε συνδυασμό με τον σχεδιασμό του λοιπού οικοπέδου, αποσκοπεί στον μετασχηματισμό του σε δημόσιο χώρο αναψυχής και δραστηριότητας, με λειτουργίες που στοχεύουν στην ζύμωση ποικίλων κοινωνικών ομάδων. Προτείνεται η αποκατάσταση του παραμελημένου βιομηχανικού κελύφους και η τοποθέτηση νέων χρήσεων. Συγκεκριμένα, δημιουργούνται: κλειστός χώρος απασχόλησης παιδιών προσχολικής ηλικίας, εργαστήρια για την αξιοποίηση τους από φοιτητικές ομάδες, βιβλιοθήκη και διάφοροι πολυχώροι. Επιπλέον συνδυάζεται το παλιό με το νέο,  με τον σχεδιασμό του οικοπέδου σε 3 άξονες: α. τον σχεδιασμό του δημόσιου χώρου, με όγκους πρασίνου, skatepark, γήπεδο ποδοσφαίρου, μικρής παιδικής χαράς και μίας κεντρικής πλατείας με την δυνατότητα φιλοξενίας εκδηλώσεων και συναυλιών β. την κατασκευή στεγάστρου, για την εξυπηρέτηση λαϊκής αγοράς  και γ. την ανέγερση νέων κτηριακών εγκαταστάσεων, με αναψυκτήριο και βοηθητικούς χώρους για τις αθλητικές εγκαταστάσεις .
