description: Η παρούσα ερευνητική εργασία εξετάζει δυνατότητες γεφύρωσης φυσικού-ψηφιακού, απτού-εικονικού. Στόχος της εργασίας είναι η διερεύνηση τρόπων ενίσχυσης της εμπειρίας και αλληλεπίδρασης με το γύρω φυσικό περιβάλλον μέσω των σύγχρονων τεχνολογικών εργαλείων, ενδυναμώνοντας τη σχέση ανθρώπου-περιβάλλοντος. Τα τεχνολογικά μέσα που αναπτύσσονται τις τελευταίες δεκαετίες δημιουργούν νέες μορφές επικοινωνίας και δικτύωσης μεταξύ των ανθρώπων αλλά και μεταξύ των ανθρώπων και του χώρου. Ο εικονικός διαδικτυακός κόσμος μεταφέρεται σταδιακά στον πραγματικό χώρο, μεταβάλλοντας την χωρική αντίληψη και τον τρόπο που τον βιώνουμε. Η επαυξημένη πραγματικότητα, ένα ταχέως αναπτυσσόμενο ερευνητικό πεδίο στον χώρο της εικονικής (ή ιδεατής) πραγματικότητας, επιτρέπει την προσθήκη ψηφιακών δεδομένων, τα οποία μπορεί να επεξεργαστεί ο χρήστης, επάνω στο πραγματικό περιβάλλον. Σε συνδυασμό με τις φορητές συσκευές και τα ασύρματα δίκτυα, ο χρήστης δεν χρειάζεται να αποσυνδεθεί από τον φυσικό χώρο για να εισέλθει στον ψηφιακό. Αντίθετα το πραγματικό περιβάλλον εμπλουτίζεται με ψηφιακά πληροφορίες κι ο άνθρωπος αποκτά πιο ενεργό ρόλο στη διαμόρφωση του. Αν και οι δυνατότητες των τεχνολογιών που μελετώνται έχουν γίνει άμεσα αντιληπτές, αποτελούν ωστόσο μία πρώτη μόνο εικόνα της νέας μορφής πραγματικότητας που σχηματίζεται από τη συγχώνευση πραγματικού και ψηφιακού κόσμου.

description: We present techniques for bridging the gap between idealized inverse covariance weighted quadratic estimation of 21 cm power spectra and the real-world challenges presented universally by interferometric observation. By carefully evaluating various estimators and adapting our techniques for large but incomplete data sets, we develop a robust power spectrum estimation framework that preserves the so-called "EoR window" and keeps track of estimator errors and covariances. We apply our method to observations from the 32-tile prototype of the Murchinson Widefield Array to demonstrate the importance of a judicious analysis technique. Lastly, we apply our method to investigate the dependence of the clean EoR window on frequency--especially the frequency dependence of the so-called "wedge" feature--and establish upper limits on the power spectrum from z = 6.2 to z = 11.7. Our lowest limit is Delta(k) < 0.3 Kelvin at 95% confidence at a comoving scale k = 0.046 Mpc^-1 and z = 9.5.

description: Background: For some patients, positive cancer screening test results can be a stressful experience which can affect future screening compliance and increase the utilization of healthcare services unrelated to medically-indicated follow-up. Methods: Among 483,216 individuals, aged 50–75 years, who completed a fecal immunochemical test to screen for colorectal cancer at a large integrated health care setting between 2007 and 2011, we evaluated whether a positive test was associated with a net change in outpatient primary care visit use in the year following screening. We used multivariable regression models to evaluate the relationship between test result group and net changes in primary care visits following fecal immunochemical test. Results: In the year following the fecal immunochemical test, utilization increased by 0.60 clinic visits for true positives. The absolute change in visits was largest (3.00) among test positive patients diagnosed with colorectal cancer but significant small increases were also found for polypectomy/no neoplasia (0.36) and normal exam/no polypectomy (0.17). Groups that demonstrated an increase in net visit use compared to the true negative group included true positives (OR 1.60, 95% CI 1.54–1.66), and positive groups with colorectal cancer diagnosis (OR 7.19, 95%CI 6.12–8.44), polypectomy/no neoplasia (OR 1.37, 95%CI 1.27–1.48) and normal exam/no polypectomy groups (OR 1.24, 95%CI 1.18–1.30). Conclusion: Given the large size of outreach programs, these small changes can cumulatively generate thousands of excess visits and have substantial impacts on total health care utilization and thus should be included in colorectal cancer screening cost models and their causes investigated further.

description: The densest amorphous packing of rigid particles is known as random close packing. It has long been appreciated that higher densities are achieved by using collections of particles with a variety of sizes. The variety of sizes is often quantified by the polydispersity of the particle size distribution: the standard deviation of the radius divided by the mean radius. Several prior studies quantified the increase of the packing density as a function of polydispersity. Of course, a particle size distribution is also characterized by its skewness, kurtosis, and higher moments, but the influence of these parameters has not been carefully quantified before. In this work, we numerically generate many packings with different particle radii distributions, varying polydispersity and skewness independently of one another. We find two significant results. First, the skewness can have a significant effect on the packing density and in some cases can have a larger effect than polydispersity. Second, the packing fraction is relatively insensitive to the value of the kurtosis. We present a simple empirical formula for the value of the random close packing density as a function of polydispersity and skewness.

description: Multi-user Multiple-Input Multiple-Output (MIMO) offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering environment is not required, and resource allocation is simplified because every active terminal utilizes all of the time-frequency bins. However, multi-user MIMO, as originally envisioned with roughly equal numbers of service-antennas and terminals and frequency division duplex operation, is not a scalable technology. Massive MIMO (also known as "Large-Scale Antenna Systems", "Very Large MIMO", "Hyper MIMO", "Full-Dimension MIMO" & "ARGOS") makes a clean break with current practice through the use of a large excess of service-antennas over active terminals and time division duplex operation. Extra antennas help by focusing energy into ever-smaller regions of space to bring huge improvements in throughput and radiated energy efficiency. Other benefits of massive MIMO include the extensive use of inexpensive low-power components, reduced latency, simplification of the media access control (MAC) layer, and robustness to intentional jamming. The anticipated throughput depend on the propagation environment providing asymptotically orthogonal channels to the terminals, but so far experiments have not disclosed any limitations in this regard. While massive MIMO renders many traditional research problems irrelevant, it uncovers entirely new problems that urgently need attention: the challenge of making many low-cost low-precision components that work effectively together, acquisition and synchronization for newly-joined terminals, the exploitation of extra degrees of freedom provided by the excess of service-antennas, reducing internal power consumption to achieve total energy efficiency reductions, and finding new deployment scenarios. This paper presents an overview of the massive MIMO concept and contemporary research.

description: Two-dimensional (2D) compounds provide unique building blocks for novel layered devices and hybrid photonic structures. However, large surface-to-volume ratio in thin films enhances the significance of surface interactions and charging effects requiring new understanding. Here we use micro-photoluminescence (PL) and ultrasonic force microscopy to explore the influence of the dielectric environment on optical properties of a few monolayer MoS2 films. PL spectra for MoS2 films deposited on SiO2 substrates are found to vary widely. This film-to-film variation is suppressed by additional capping of MoS2 with SiO2 and SiN, improving mechanical coupling of MoS2 with surrounding dielectrics. We show that the observed PL non-uniformities are related to strong variation in the local electron charging of MoS2 films. In completely encapsulated films, negative charging is enhanced leading to uniform optical properties. Observed great sensitivity of optical characteristics of 2D films to surface interactions has important implications for optoelectronics applications of layered materials.

description: Recently, several groups have reported spin-dependent thermoelectric effects in magnetic tunnel junctions. In this paper, we present a setup for time-resolved measurements of thermovoltages and thermocurrents of a single micro- to nanometer-scaled tunnel junction. An electrically modulated diode laser is used to create a temperature gradient across the tunnel junction layer stack. This laser modulation technique enables the recording of time-dependent thermovoltage signals with a temporal resolution only limited by the preamplifier for the thermovoltage. So far, time-dependent thermovoltage could not be interpreted. Now, with the setup presented in this paper, it is possible to distinguish different Seebeck voltage contributions to the overall measured voltage signal in the μs time regime. A model circuit is developed that explains those voltage contributions on different sample types. Further, it will be shown that a voltage signal arising from the magnetic tunnel junction can only be observed when the laser spot is directly centered on top of the magnetic tunnel junction, which allows a lateral separation of the effects.

description: In this paper, we analyze in detail with numerical simulations how the mask effect can influence the weak lensing peak statistics reconstructed from the shear measurement of background galaxies. It is found that high peak fractions are systematically enhanced due to masks, the larger the masked area, the higher the enhancement. In the case with about $13\%$ of the total masked area, the fraction of peaks with SNR $ν\ge 3$ is $\sim 11\%$ in comparison with $\sim 7\%$ of the mask-free case in our considered cosmological model. This can induce a large bias on cosmological studies with weak lensing peak statistics. Even for a survey area of $9\hbox{ deg}^2$, the bias in $(Ω_m, σ_8)$ is already close to $3σ$. It is noted that most of the affected peaks are close to the masked regions. Therefore excluding peaks in those regions can reduce the bias but at the expense of loosing usable survey areas. Further investigations find that the enhancement of high peaks number can be largely attributed to higher noise led by the fewer number of galaxies usable in the reconstruction. Based on Fan et al. (2010), we develop a model in which we exclude only those large masks with radius larger than $3\arcmin. For the remained part, we treat the areas close to and away from the masked regions separately with different noise levels. It is shown that this two-noise-level model can account for the mask effect on peak statistics very well and the cosmological bias is significantly reduced.

description: We examine the notion of nonclassicality in terms of quasiprobability distributions. In particular, we do not only ask if a specific quasiprobability can be interpreted as a classical probability density, but require that characteristic features of classical electrodynamics are resembled. We show that the only quasiprobabilities which correctly describe the superposition principle of classical electromagnetic fields are the $s$-parameterized quasiprobabilities. Furthermore, the Glauber-Sudarshan P function is the only quantum-mechanical quasiprobability which is transformed at a classical attenuator in the same way as a classical probability distribution. This result strengthens the definition of nonclassicality in terms of the P function, in contrast to possible definitions in terms of other quasiprobabilities.

description: Ο σύγχρονος αστικός άνθρωπος έχει αποξενωθεί από το φυσικό περιβάλλον, με αποτέλεσμα αυτό να έχει μετατραπεί σε ένα ανοίκειο περιβάλλον. Στις πόλεις, οι οποίες συγκεντρώνουν την πλειοψηφία  του πληθυσμού, το πράσινο συρρικνώνεται και υποβαθμίζεται συνεχώς, παρά την αναγκαιότητα και την θετική επίδραση του στον άνθρωπο. Το θέμα της διπλωματικής εργασίας αφορά την ενίσχυση της βιωματικής εμπειρίας σε χώρους αστικού πρασίνου, μέσα από το συνδυασμό πραγματικού και ψηφιακού περιβάλλοντος. Στόχος είναι η (επανα)οικειοποίηση δημόσιων χώρων πρασίνου και η σύνδεση του ατόμου με φυσικά στοιχεία. Στη σύγχρονη εποχή, η κυριαρχία της τεχνολογία και των εικόνων μετασχηματίζει την χωρική αντίληψη και οι συσκευές φορητής επικοινωνίας, όπως το κινητό τηλέφωνο, αποτελούν την ενδιάμεση κατάσταση ανάμεσα στο σώμα και στο δημόσιο χώρο. Αναγνωρίζοντας  την κατάσταση αυτή, η τεχνολογία πληροφοριών και επικοινωνίας ενσωματώνεται στο σχεδιασμό της εμπειρίας και χρησιμοποιείται ως μέσο αλλαγής συμπεριφοράς  και επαύξησης των χαρακτηριστικών του περιβάλλοντος. Αντικείμενο της παρούσας διπλωματικής εργασίας είναι ο σχεδιασμός υλικών και εικονικών επεμβάσεων σε σημεία πρασίνου στο κέντρο και την παλιά πόλη των Χανίων. Η εργασία αποτελείται από ένα παιχνίδι επαυξημένης πραγματικότητας για φορητές συσκευές και αρχιτεκτονικές κατασκευές, ο συνδυασμός των οποίων δημιουργεί υβριδικούς χώρους στα σημεία ενδιαφέροντος.  Η συγχώνευση εικονικών και υλικών επεμβάσεων μετατρέπει τους υφιστάμενους δημόσιους χώρους πρασίνου σε χώρους δραστηριότητας, κοινωνικοποίησης και εκτόνωσης από το άγχος των αστικών κέντρων.

description: In this work we describe the manufacturing of cellulosic, cell compatible scaffolds with an inherent 3D origami crease pattern for applications in cardiac tissue engineering. Different cellulosic materials were studied, among them cotton linters, fibers obtained from eucalyptus, pine, spruce and lyocell. Formed sheets made of cotton linters were chosen for further study due to the highest biocompatibility and mechanical properties best suited for cardiomyocytes in wet and dry conditions: E - modulus of 0.8 GPa, tensile strength of 4.7 MPa and tensile strength in wet environment of 2.28 MPa. Cell alignment is desired to achieve directional contraction of the cardiac tissue, and several options were investigated to achieve fiber alignment, e.g. a dynamic sheet former and Rapid Köthen sheet former. Although the orientation was minimal, cells cultured on the cellulose fibers grew and aligned along the fibers. Origami inspired crease patterns were applied to the cellulose scaffolds in order to introduce directional flexibility beneficial for cardiac contraction. The transfer of a Miura-ori crease pattern was successfully applied in two ways: folding of the dried sheet between PET foils pre-formed in a 3D printed mold, and in situ wet fiber molding on a 3D-patterned mesh mounted in the sheet former’s sieve section. The latter approach enables upscaling for potential mass production.

description: The first result of AMS-02 confirms the positron fraction excess observed by PAMELA, but the spectrum is somewhat softer than that of PAMELA. In the dark matter (DM) interpretation it brings a tension between AMS-02 and Fermi-LAT, which reported an excess of the electron plus positron flux. In this work we point out that the asymmetric cosmic ray from asymmetric dark matter (ADM) decay relaxes the tension. It is found that in the case of two-body decay a bosonic ADM around 2.4 TeV and decaying into $μ^-τ^+$ can significantly improve the fits. Based on the $R-$parity-violating supersymmetry with operators $LLE^c$, we propose a minimal model to realize that ADM. The model introduces only a pair of singlets $(X,\bar X)$ with a tiny coupling $LH_uX$, which makes the ADM share the lepton asymmetry and decay into $μ^-τ^+$ along the operator $LLE^c$.

description: Ο σύγχρονος κόσμος μπορεί να χαρακτηριστεί ως ένα σύνολο από δίκτυα, ροές και μεταβάσεις. Αναλογιζόμενοι τον χρόνο που αφιερώνει κανείς σήμερα στην δραστηριότητα της μετακίνησης συνειδητοποιούμε ότι μεγάλο μέρος της καθημερινής ζωής διαδραματίζεται πλέον σε χώρους από τους οποίους διερχόμαστε σχεδόν υποχρεωτικά έτσι ώστε να εκπληρώσουμε συγκεκριμένες ανάγκες μας.

Υπό αυτό το πρίσμα, παρουσιάζονται σύγχρονα κτίρια μεταφορικών υποδομών και επιχειρείται η εξαγωγή συμπερασμάτων σχετικά με τις σύγχρονες τάσεις σχεδιασμού.  Τα κτίρια τα οποία μελετώνται είναι ο σιδηροδρομικός σταθμός στο Arnhem των UN Studio, o αεροπορικός σταθμός στο Stansted του γραφείου Foster&Partners και o λιμενικός σταθμός του Rem Koolhaas και των ΟΜΑ στην Zeebrugge.

Παράλληλα, η ανάγκη για ένα κλειστό χώρο στον οποίο θα εκτίθενται μικρότερα αντικείμενα τα οποία χρησιμοποιούνταν για εξόρυξη μέσα στις στοές, οδηγεί στον σχεδιασμό ενός κλειστού χώρου- Μουσείου. Ο χώρος αυτός περιέχει επίσης αίθουσες διαλέξεων και ενημέρωσης σχετικά με την μεταλλευτική κληρονομιά.

description: We perform two dimensional hydrodynamic numerical simulations to study the positive active galactic nucleus feedback which triggers, rather than suppresses, star formation. Recently, it was shown by Nayakshin et al. and Ishibashi et al. that star formation occurs when the cold interstellar medium is squeezed by the impact of mass outflow or radiation pressure, respectively. Mass outflow is ubiquitous in this astrophysical context, and radiation pressure is also important if the AGN is luminous. For the first time in this subject, we incorporate both mass outflow feedback and radiative feedback into our model. Consequently, the ISM is shocked into shells by the AGN feedback, and these shells soon fragment into clumps and filaments because of Rayleigh-Taylor and thermal instabilities. We have two major findings: (1) the star formation rate can indeed be very large in the clumps and filaments. However, the resultant star formation rate density is too large compared with previous works, which is mainly because we ignore the fact that most of the stars that are formed would be disrupted when they move away from the galactic center. (2) Although radiation pressure feedback has a limited effect, when mass outflow feedback is also included, they reinforce each other. Specifically, in the gas-poor case, mass outflow is always the dominant contributor to feedback.

description: It is known that a reliable geometric quantifier of discord-like correlations can be built by employing the so-called trace distance. This is used to measure how far the state under investigation is from the closest "classical-quantum" one. To date, the explicit calculation of this indicator for two qubits was accomplished only for states such that the reduced density matrix of the measured party is maximally mixed, a class that includes Bell-diagonal states. Here, we first reduce the required optimization for a general two-qubit state to the minimization of an explicit two-variable function. Using this framework, we show next that the minimum can be analytically worked out in a number of relevant cases including quantum-classical and X states. This provides an explicit and compact expression for the trace distance discord of an arbitrary state belonging to either of these important classes of density matrices.

description: We give a new probabilistic algorithm for interpolating a "sparse" polynomial f given by a straight-line program. Our algorithm constructs an approximation f* of f, such that their difference probably has at most half the number of terms of f, then recurses on their difference. Our approach builds on previous work by Garg and Schost (2009), and Giesbrecht and Roche (2011), and is asymptotically more efficient in terms of the total cost of the probes required than previous methods, in many cases.

description: We analyzed a Kepler light curve of KIC 8751494, a recently recognized novalike cataclysmic variable in the Kepler field. We detected a stable periodicity of 0.114379(1) d, which we identified as being the binary's orbital period. The stronger photometric period around 0.12245 d, which had been detected from the ground-based observation, was found to be variable, and we identified this period as being the positive superhump period. This superhump period showed short-term (10-20 d) and strong variations in period most unexpectedly when the object entered a slightly faint state. The fractional superhump excess varied as large as ~30%. The variation of the period very well traced the variation of the brightness of the system. The time-scales of this variation of the superhump period was too slow to be interpreted as the variation caused by the change in the disk radius due to the thermal disk instability. We interpreted that the period variation was caused by the varying pressure effect on the period of positive superhumps. This finding suggests that the pressure effect, in at least novalike systems, plays a very important (up to ~30% in the precession rate) role in producing the period of the positive superhumps. We also described a possible detection of the negative superhumps with a varying period of 0.1071-0.1081 d in the Q14 run of the Kepler data. We also found that the phase of the velocity variation of the emission lines reported in the earlier study is compatible with the SW Sex-type classification. Further, we introduced a new two-dimentional period analysis using least absolute shrinkage and selection operator (Lasso) and showed superior advantage of this method.

description: As the world water resources continue to deplete, reuse and recycling of greywater has become an alternative potential sustainable solution to reduce the stress on fresh water resources. The objective of this thesis is to assess the different technological approaches for greywater treatments and to provide an extensive review on the application of compacted decentralized solutions to produce high quality treated water suitable for non-potable household uses. The paper reviewed various solutions of decentralised systems for greywater treatment. Various compacted treatment technologies have also been examined. Both physical, chemical and biological treatment systems and their combinations are assessed. Moreover, case studies mainly on nature-based solutions, constructed wetland, presented. The thesis revealed that these systems are effective and have the potential of treating greywater to the level of good quality for safe discharge or for non-potable fit-for-purpose uses. Constructed wetlands, green roofs and green walls are recently receiving more attention in decentralized urban greywater treatment and are proved to have high removal efficiency of suspended solids, organic matter, microorganisms and micro-pollutants. These technologies are eco-friendly, energy efficient, less expensive and easy to operate and maintain. Treating greywater is not only an important option to help manage the balance between the demand and supply of water and reduce the burden on fresh water reserves, but also it provides an opportunity to avert environmental, surface and ground water pollution.

description: The Earth Occultation Technique (EOT) has been applied to Fermi's Gamma-ray Burst Monitor (GBM) to perform all-sky monitoring for a predetermined catalog of hard X-ray/soft gamma-ray sources. In order to search for sources not in the catalog, thus completing the catalog and reducing a source of systematic error in EOT, an imaging method has been developed -- Imaging with a Differential filter using the Earth Occultation Method (IDEOM). IDEOM is a tomographic imaging method that takes advantage of the orbital precession of the Fermi satellite. Using IDEOM, all-sky reconstructions have been generated for ~sim 4 years of GBM data in the 12-50 keV, 50-100 keV and 100-300 keV energy bands in search of sources otherwise unmodeled by the GBM occultation analysis. IDEOM analysis resulted in the detection of 57 sources in the 12-50 keV energy band, 23 sources in the 50-100 keV energy band, and 7 sources in the 100-300 keV energy band. Seventeen sources were not present in the original GBM-EOT catalog and have now been added. We also present the first joined averaged spectra for four persistent sources detected by GBM using EOT and by the Large Area Telescope (LAT) on Fermi: NGC 1275, 3C 273, Cen A, and the Crab.

Evolution Of Post-Impact Remnant Helium Stars In Type Ia Supernova Remnants Within The Single-Degenerate Scenario

description: The progenitor systems of Type Ia supernovae (SNe Ia) are still under debate. Based on recent hydrodynamics simulations, non-degenerate companions in the single-degenerate scenario (SDS) should survive the supernova impact. One way to distinguish between the SDS and the double-degenerate scenario is to search for the post-impact remnant stars (PIRSs) in SN Ia remnants. Using a technique that combines multi-dimensional hydrodynamics simulations with one-dimensional stellar evolution simulations, we have examined the post-impact evolution of helium-rich binary companions in the SDS. It is found that these helium-rich PIRSs (He PIRSs) dramatically expand and evolve to a luminous phase ($L\sim 10^4 L_\odot$) about 10 years after a supernova explosion. Subsequently, they contract and evolve to become hot blue-subdwarf-like (sdO-like) stars by releasing gravitational energy, persisting as sdO-like stars for several million years before evolving to the helium red-giant phase. We therefore predict that a luminous OB-like star should be detectable within $\sim 30$ years after the SN explosion. Thereafter, it will shrink and become an sdO-like star in the central regions of SN Ia remnants within star-forming regions for SN Ia progenitors evolved via the helium-star channel in the SDS. These He PIRSs are predicted to be rapidly rotating ($v_{\rm rot} \gtrsim 50$ km s$^{-1}$) and to have high spatial velocities ($v_{\rm linear} \gtrsim 500$ km s$^{-1}$). Furthermore, if supernova remnants have diffused away and are not recognizable at a later stage, He PIRSs could be an additional source of single sdO stars and/or hypervelocity stars.

description: We discuss the possibility that we could obtain some hints of the heavy physics during inflation by analyzing local features of the primordial bispectrum. A heavy scalar field could leave large signatures in the primordial spectra through the parametric resonance between its background oscillation and the fluctuations. Since the duration of the heavy-mode oscillations is finite, the effect of the resonance is localized in momentum space. In this paper, we show that the bispectrum is amplified when such a resonance occurs, and that the peak amplitude of the feature can be O(10^{1-2}), or as large as O(10^5) depending on the type of interactions. In particular, the resonance can give large contributions in finitely squeezed configurations, while the bispectrum cannot be large in the exact squeezed limit. We also find that there is a relation between the scales at which the features appear in the bispectrum and the power spectrum, and that the feature in the bispectrum can be much larger than that in the power spectrum. If correlated features are observed at characteristic scales in the primordial spectra, it will indicate the presence of heavy degrees of freedom. By analyzing these features, we may be able to obtain some information on the physics behind inflation.
