description: Arbeitspapier 54 des Hochschulforums Digitalisierung. Auswertung einer Umfrage unter ca. 10.000 Studierenden, durchgeführt durch die DigitalChangeMaker, studentische Zukunfts-AG des Hochschulforums Digitalisierung. Zusammenfassung Fast die Hälfte der Studierenden nutzt private Plattformen für Studienzwecke, obwohl sich eine deutliche Mehrheit wünscht, das nicht zu tun. Studierende bewerten die Digitalisierung fast aller für die Organisation von Studium und Lehre relevanten Prozesse mehrheitlich als wichtig. Einige Eigenschaften digitaler Tools werden fast durchweg als erachtet: ein zuverlässiges Funktionieren, übersichtliche Funktionen und der Schutz persönlicher Daten. Die Verfügbarkeit von digitalen Medien führt dazu, dass sie als wichtiger für das Studium bewertet werden. Ihr tatsächlicher Nutzen erschließt sich den Studierenden also vermutlich erst, wenn sie mit ihnen arbeiten. Nur etwa jede/r zweite Studierende, der oder die die Digitalisierung in Studium und Lehre mitgestalten möchte, hat die Gelegenheit dazu. Männliche Studierende möchten eher mitgestalten als weibliche. Für Erstakademiker*innen geht ein ehrenamtliches Engagement an der Hochschule möglicherweise mit besonderen Herausforderungen einher. Summary Almost half of the students uses private platforms for study purposes although a clear majority wishes to not do so. Students predominantly consider the digitalization of almost all processes that are relevant for the organisation of their studies as important. Some properties of digital tools are important to virtually all students: reliable functioning, clearly arranged functions and the protection of private data. The availability of digital media leads to increased ratings of their importance. The actual value of the media is recognized by students only when they use it. Only every second student who wishes to help shape digitalization of learning and teaching has the opportunity to do so. Male students are more likely to want to help shape digitalization. First generation college students may face special barriers to engagement in extracurricular activities

description: We present an architecture for arbitrarily scalable boson-sampling using two nested fiber loops. The architecture has fixed experimental complexity, irrespective of the size of the desired interferometer, whose scale is limited only by fiber and switch loss rates. The architecture employs time-bin encoding, whereby the incident photons form a pulse train, which enters the loops. Dynamically controlled loop coupling ratios allow the construction of the arbitrary linear optics interferometers required for boson-sampling. The architecture employs only a single point of interference and may thus be easier to stabilize than other approaches. The scheme has polynomial complexity and could be realized using demonstrated present-day technologies.

description: The stability analysis of model predictive control schemes without terminal constraints and/or costs has attracted considerable attention during the last years. We pursue a recently proposed approach which can be used to determine a suitable optimization horizon length for nonlinear control systems governed by ordinary differential equations. In this context, we firstly show how the essential growth assumption involved in this methodology can be derived and demonstrate this technique by means of a numerical example. Secondly, inspired by corresponding results, we develop an algorithm which allows to reduce the required optimization horizon length while maintaining asymptotic stability or a desired performance bound. Last, this basic algorithm is further elaborated in order to enhance its robustness properties.

title: The Effect of Natural Disasters on Climate Change and Sea Level Rise
Creators: name: Riekers, Nicole
Publisher: name: Old Dominion University Libraries
Year: 2015

description: This study, led by Dr. Daniel Richards and Mrs. Megan McKittrick, with additional assistance from Old Dominion University students enrolled in English 231C Technical Writing, utilizes an approach called “productive usability” in Climate Central’s testing of their most recent technology, Risk Finder. The client for this non-profit research study is Dan Rizza, Manager and Research Associate of Climate Central. Climate Central is an independent organization that conducts research on climate change and communicates their findings to the general American public. The Risk Finder tool, created in October 2013, is an interactive portion of Climate Central’s “Surging Seas” website that anyone can access to view the vulnerability of their city, county, or state in relation to flooding aggravated by sea level rise (Climate Central, 2014). Undergraduate students from Mrs. McKittrick’s English 231C Technical Writing course use systematic sampling from the Polk directories in the Old Dominion University library to create a list of 8-10 possible participants for testing the Risk Finder technology. After the participants are chosen, they go through a process that consists of a pre-test introduction and interview, an observed use with a talk aloud protocol, and a post-test interview. Following this productive usability testing, each participant’s audio file is transcribed and coded for recurring themes. Through their assistance in making the Risk Finder tool more user-friendly, these participants help the community more clearly understand the dangers of sea-level rise. Educating the general public about how climate change directly affects them and their community helps to ensure that risk communication will continue to be an important topic

description: The quasi-local formulation of conserved charges through the off-shell approach is extended to cover the asymptotic symmetry generators. By introducing identically conserved currents which are appropriate for asymptotic Killing vectors, we show that the asymptotic symmetry generators can be understood as quasi-local charges. We also show that this construction is completely consistent with the on-shell method.

description: Spices have long been an important component in the preparation of food, and some have medicinal properties as well. Stegobium paniceum, the drugstore beetle, has been detected in spices but no detailed information is available on its infestation in certain locally-available spices. Objective of this study was to find out the degree of infestation by S. paniceum in ten different spices. Twenty adults of S. paniceum were introduced into a vial containing a particular spice, maintained for two weeks and shifted out. These were maintained under ambient environmental conditions and the progeny adults emerged in each medium was counted at two week intervals for three months. The progeny produced varied with the food medium; the highest progeny was recorded in coriander whereas the lowest progeny was recorded in cinnamon, clove, dill seeds, cardamom, chilli, pepper corn and turmeric powder. This study reveals that S. paniceum infests a wide array of spices at different levels. This information is important for taking necessary steps to protect the spices from the infestation of S. paniceum.

description: Adults and larvae of Dienerella argus (Reitter) (Coleoptera: Latridiidae) feed on fungi and are frequently found in indoor, moldy areas. The basic biology of this species, other than its feeding habits, has not been determined. In this study, the developmental parameters of the beetle were investigated using dried hyphae and conidia from three fungi that are common in living areas. The developmental periods of the beetle on Cladosporium cladosporioides, Penicillium citrinum, and P. decumbens were examined at 16, 20, 24, 28, 32 °C / 70–75 % RH under dark conditions. The low developmental threshold temperatures and thermal constants calculated from egg to adult emergence were 10.5 °C and 526 DD (degree day), 9.0 °C and 500 DD, and 10.9 °C and 370 DD on C. cladosporioides, P. citrinum, and P. decumbens, respectively. These developmental parameters indicate that these beetles can breed year-round in indoor areas that are in air-conditioned facilities.

description: Despite intensive research a physical explanation of high Tc superconductors remains elusive. One reason for this is that these materials have generally a very complex structure making useless theoretical models for a homogeneous system. Little is known on the control of the critical temperature by the space disposition of defects because of lack of suitable experimental probes. X-ray diffraction and neutron scattering experiments used to investigate y oxygen dopants in YBa2Cu3O 6+y lack of spatial resolution. Here we report the spatial imaging of dopants distribution in-homogeneity in YBa2Cu3O6.67 using scanning nano X-ray diffraction. By changing the X-ray beam size from 1 micron to 300 nm of diameter, the lattice inhomogeneity increases. The ordered oxygen puddles size distribution vary between 6-8 nm using 1x1 μm2 beam, while it is between 5-12 nm with a fat tail using the 300x300 nm2 beam. The increased inhomogeneity at the nanoscale points toward an intrinsic granular complexity.

description: Incident solar radiation (insolation) passing through the forest canopy to the ground surface is either absorbed or scattered. This phenomenon is known as attenuation and is measured in forest ecology using the extinction coefficient (K). The effect of K on understory photosynthetically available radiation (PAR) and microclimate may be associated with plant species diversity, as distinct species and communities have unique habitat requirements. The objective of his study is to model insolation and canopy structure to observe effects of predictors representative of K on understory plant biodiversity using remotely sensed and botanical field data.
We used two taxonomic diversity indexes (Menhinick’s and Simpson) to describe the surveyed plant community in a natural temperate montane forest, modeling the index values at the plot level as response variables. Independent variables included localized area incident solar radiation estimated using a solar model, LiDAR derived canopy height model, effective leaf area index (LAI) estimates derived from multi-spectral imagery and canopy strata metrics derived from LiDAR point cloud data. Considering the impact of atmospheric components above the canopy layer and an assumption that incident short-wave solar radiation to Earth’s vegetated surfaces is primarily absorbed in the canopy layer, we used a multiple linear model to predict canopy metrics controlling the sub-canopy surface radiant flux to develop the hypothesis that 1.) canopy structural variability is associated with the biodiversity of stand plant species through habitat partitioning and, 2.) a prediction model can be developed to validate this relationship spatially. The available data indicated many and varied correlations between predictor and response variables as well as a statistically valid linear model comprising the canopy relief, the texture, and vegetation density with understory plant diversity. When analyzed for spatial autocorrelation, the predicted biodiversity data exhibited non-random spatial continuity.

Subjects: subject: Populations and Evolution (q-bio.PE)

description: We study stochastic evolution of optional games on simple graphs. There are two strategies, A and B, whose interaction is described by a general payoff matrix. In addition there are one or several possibilities to opt out from the game by adopting loner strategies. Optional games lead to relaxed social dilemmas. Here we explore the interaction between spatial structure and optional games. We find that increasing the number of loner strategies (or equivalently increasing mutational bias toward loner strategies) facilitates evolution of cooperation both in well-mixed and in structured populations. We derive various limits for weak selection and large population size. For some cases we derive analytic results for strong selection. We also analyze strategy selection numerically for finite selection intensity and discuss combined effects of optionality and spatial structure.

description: While it is known that the nature and the arrangement of defects in complex oxides have an impact on the material functionalities little is known on control of superconductivity by oxygen interstitial organization in cuprates. Here we report direct compelling evidence for the control of Tc, by manipulation of the superconducting granular networks of nanoscale puddles, made of ordered oxygen stripes, in a single crystal of YBa2Cu3O6.5+y with average formal hole doping p close to 1/8. Upon thermal treatments we were able to switch from a first network of oxygen defects striped puddles with OVIII modulation (qOVIII(a*)=(h+3/8,k,0) and qOVIII(a*)=(h+5/8,k,0)), to second network characterized by OXVI modulation (qOXVI(a*)=(h+7/16,k,0) and qOXVI(a*)=(h+9/16,k,0)), and finally to a third network with puddles of OV periodicity (qOV(a*)=(4/10,1,0) and qOV(a*)=(6/10,1,0)). We map the microscopic spatial evolution of the out of plane OVIII, OXVI and OV puddles nano-size distribution via scanning micro-diffraction measurements. In particular, we calculated the number of oxygen chains (n) and the charge density (holes concentration p) inside each puddle, analyzing areas of 160x80 μm2, and recording 12800 diffraction patterns to reconstruct each spatial map. The high spatial inhomogeneity shown by all the reconstructed spatial maps reflects the intrinsic granular structure that characterizes cuprates and iron-chalcogenides, disclosing the presence of several complex networks of coexisting superconducting domains with different lattice modulations, charge density and different gaps like in the proposed multi-gaps scenario called superstripes.

description: An equivalent model for a multi-input multi-output (MIMO) communication system with orthogonal space-time block codes (OSTBCs) is proposed based on a newly revealed connection between OSTBCs and Euclidean codes. Examples of distance spectra, signal constellations, and signal coordinate diagrams of Euclidean codes equivalent to simplest OSTBCs are given. A new asymptotic upper bound for the symbol error rate (SER) of OSTBCs, based on the distance spectra of the introduced equivalent Euclidean codes is derived, and new general design criteria for signal constellations of the optimal OSTBC are proposed. Some bounds relating distance properties, dimensionality, and cardinality of OSTBCs with constituent signals of equal energy are given, and new optimal signal constellations with cardinalities M = 8 and M = 16 for Alamouti's code are designed. Using the new model for MIMO communication systems with OSTBCs, a general methodology for performance analysis of OSTBCs is developed. As an example of the application of this methodology, an exact evaluation of the SER of any OSTBC is given. Namely, a new expression for the SER of Alamouti's OSTBC with binary phase shift keying (BPSK) signals is derived.

description: We show that the interaction region of colliding protons looks completely absorptive (black) at the impact parameters up to 0.4 - 0.5 fm at the LHC energy 7 TeV. It is governed by the ratio of the elastic diffraction peak slope to the total cross section. The corresponding parameter is approximately equal to 1 at the LHC. The behavior of this ratio at higher energies will show if this region will evolve to the black disk or to the black torus. Recent fits at 7 TeV can not distinguish between these possibilities within the limits of experimental indefiniteness and of extrapolations in the regions of unmeasured transferred momenta.

Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: In this paper, we study rigidity problems for hypersurfaces with constant curvature quotients $\frac{\mathcal{H}_{2k+1}}{\mathcal{H}_{2k}}$ in the warped product manifolds. Here $\mathcal{H}_{2k}$ is the $k$-th Gauss-Bonnet curvature and $\mathcal{H}_{2k+1}$ arises from the first variation of the total integration of $\mathcal{H}_{2k}$. Hence the quotients considered here are in general different from $\frac{σ_{2k+1}}{σ_{2k}}$, where $σ_k$ are the usual mean curvatures. We prove several rigidity and Bernstein type results for compact or non-compact hypersurfaces corresponding to such quotients.

description: Let $M(N_{h,n})$ denote the mapping class group of a compact nonorientable surface of genus $h\ge 7$ and $n\le 1$ boundary components, and let $T(N_{h,n})$ be the subgroup of $M(N_{h,n})$ generated by all Dehn twists. It is known that $T(N_{h,n})$ is the unique subgroup of $M(N_{h,n})$ of index $2$. We prove that $T(N_{h,n})$ (and also $M(N_{h,n})$) contains a unique subgroup of index $2^{g-1}(2^g-1)$ up to conjugation, and a unique subgroup of index $2^{g-1}(2^g+1)$ up to conjugation, where $g=\lfloor(h-1)/2\rfloor$. The other proper subgroups of $T(N_{h,n})$ and $M(N_{h,n})$ have index greater than $2^{g-1}(2^g+1)$. In particular, the minimum index of a proper subgroup of $T(N_{h,n})$ is $2^{g-1}(2^g-1)$.

description: We study a system of interacting particles in a periodically moving external potential, within the simplest possible description of paradigmatic symmetric exclusion process on a ring. The model describes diffusion of hardcore particles where the diffusion dynamics is locally modified at a uniformly moving defect site, mimicking the effect of the periodically moving external potential. The model, though simple, exhibits remarkably rich features in particle transport, such as polarity reversal and double peaks in particle current upon variation of defect velocity and particle density. By tuning these variables, the most efficient transport can be achieved in either direction along the ring. These features can be understood in terms of a traveling density wave propagating in the system. Our results could be experimentally tested, e.g., in a system of colloidal particles driven by a moving optical tweezer.

description: Measurements of the decay strength of superallowed 0+ to 0+ nuclear beta transitions shed light on the fundamental properties of weak interactions. Because of their impact, such measurements were first reported 60 years ago in the early 1950s and have continued unabated ever since, always taking advantage of improvements in experimental techniques to achieve ever higher precision. The results helped first to shape the Electroweak Standard Model but more recently have evolved into sensitively testing that model's predictions. Today they provide the most demanding test of vector-current conservation and of the unitarity of the Cabibbo-Kobayashi-Maskawa matrix. Here, we review the experimental and theoretical methods that have been, and are being, used to characterize superallowed 0+ to 0+ beta transitions and to extract fundamentally important parameters from their analysis.

Year: 2019

description: Mobile Cloud computing is a rapidly emerging model, with new aspects and capabilities

being declared regularly. It is a technology where mobile computing and cloud computing

is merged for a better performance and capabilities. These technologies create great

opportunities for the banking sectors, particularly due to its better capabilities and

population coverage. Despite of its advantages, security risk haves got focused in mbanking

due to the nature of mobility and inherent weakness of wireless infrastructures;

that creates great opportunities for man-in-the-middle attack, sniffers, etc. Therefore, banks

should have to consider the issues of data confidentiality, integrity, and availability in short,

security of services before moving on to the cloud unless they might fail more than ever.

Ultimately, our objective is to design MobiCloud data security framework for the mbanking

system by providing data security solutions to the existing m-banking system. We

used the following approaches: literature review, design, implementation, simulation and

evaluation. CloudSim-3.0.3 and CloudSimDisk-3.0.0 simulation tools are used to design,

implement, and evaluate the proposed framework. Besides, JCrypTool is used to analyze

key and password strength for user authentication.

description: One of the issues that firms in Nigeria grapple with, is the challenge of striking a healthy and dynamic balance between the implicit cost of holding excess cash and the consequences of illiquidity due to inadequate cash holding. This study was conducted to examine the influence of financial structure on the cash holding levels of listed consumer goods companies in Nigeria. Ex-post-facto research design was adopted involving the use of secondary data as published by ten (10) companies selected from the population of 21 consumer goods companies listed on the floor of the Nigerian Exchange Group (NGX) for the period of 11 years (2012-2022). Descriptive statistics, simple linear regressions were used to analyze data collected. Cash and cash equivalent was used as the proxy for cash holding while firm size, leverage and debt-equity ratio were the proxy for financial structure. The result of the study indicated that firm size (β =

.080, t = 13.342, p = .000) had a positive and significant influence on cash holding; leverage

(β = -.009, t = -.166, p = .869) and debt-equity ratio (β = -.056, t = -.937, p-value = .351) had a negative and insignificant influence on cash holding level of consumer goods companies in Nigeria. Hence, it was concluded that of the three attributes considered, firm size exerts the most significant influence on the cash holding level of listed consumer goods companies in Nigeria. It was recommended that larger companies should assess their financial structure and consider the trade-offs between debt and cash holdings

description: Variability is examined in over 2.6 million stars covering 11 square degrees of the core of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) from VISTA Z-band observations. Generally, pulsation on the Sgr dSph giant branches appears to be excited by the internal kappa mechanism. Pulsation amplitudes appear identical between red and asymptotic (RGB/AGB) giant stars, and between unreddened carbon and oxygen-rich stars at the same luminosity. The lack of correlation between infrared excess and variability among oxygen-rich stars indicates pulsations do not contribute significantly to wind driving in oxygen-rich stars in the Sgr dSph, though the low amplitudes of these stars mean this may not apply elsewhere. The dust-enshrouded carbon stars have the highest amplitudes of the stars we observe. Only in these stars does an external kappa-mechanism-driven pulsation seem likely, caused by variations in their more-opaque carbon-rich molecules or dust. This may allow pulsation driving of winds to be effective in carbon stars. Variability can be simplified to a power law (amplitude proportional to L/T^2), as in other systems. In total, we identify 3026 variable stars (with r.m.s. variability of delta Z >~ 0.015 magnitudes), of which 176 are long-period variables associable with the upper giant branches of the Sgr dSph. We also identify 324 candidate RR Lyrae variables in the the Sgr dSph and 340 in the outer Galactic Bulge.

description: Insect mandibles are most frequently encountered fragments in processed foods. Thanks to their sclerotised and darkly pigmented nature, they usually remain intact in foods and are relatively easily detectable. Moreover, because of their complexity and variety of shapes, stored product beetle mandibles may be useful in species determination. The present work deals with a comparative morphology of two stored product bostrichid beetles, Rhyzopertha dominica and Prostephanus truncatus. The mandibles were studied using by light and scanning electron microscopy and their morphological details, overall appearance and size are provided.

description: The effect of pressure on the structural and vibrational properties of the layered molecular crystal 1,1-diamino-2,2-dinitroethelene (FOX-7) are explored by first principles calculations. We observe significant changes in the calculated structural properties with different corrections for treating van der Waals interactions to Density Functional Theory (DFT), as compared with standard DFT functionals. In particular, the calculated ground state lattice parameters, volume and bulk modulus obtained with Grimme's scheme are found to agree well with experiments. The calculated vibrational frequencies demonstrates the dependence of the intra and inter-molecular interactions in FOX-7 under pressure. In addition, we also found a significant increment in the N-H...O hydrogen bond strength under compression. This is explained by the change in bond lengths between nitrogen, hydrogen and oxygen atoms, as well as calculated IR spectra under pressure. Finally, the computed band gap is about 2.3 eV with GGA, and is enhanced to 5.1 eV with the GW approximation, which reveals the importance of performing quasiparticle calculations in high energy density materials.

All optical diode based on dipole modes of Kerr microcavity in asymmetric L-shaped photonic crystal waveguide

description: A design of all optical diode in $L$-shaped photonic crystal waveguide is proposed that uses the multistability of single nonlinear Kerr microcavity with two dipole modes. Asymmetry of the waveguide is achieved by difference in coupling of the dipole modes with the left and right legs of waveguide. By use of coupled mode theory we present domains in axis of light frequency and amplitude where an extremely high transmission contrast can be achieved. The direction of optical diode transmission can be governed by power and frequency of injecting light. The theory agrees with numerical solution of the Maxwell equations.
Towards Geographical Information Ecosystems

description: Since the late 1980s the geographic information community in most parts of the world initiated activities towards a more efficient and effective operation of geographic information in the public sector. Spatial data infrastructures developed from provider driven towards user driven infrastructures focusing on the delivery of high quality basic geodata to well-known user groups. Open data and APIs were embraced by the geodomain resulting in an overwhelming amount of unknown users, using our data for unknown purposes. Recently the concepts of open data ecosystem and open Spatial Data Infrastructure (SDI) were introduced, suggesting a fundamental change in the way we operate our SDIs. This presentation will address these new concepts and discuss how they are different from spatial data infrastructures: Do we really need to change the way we operate our SDIs today in order to be ready for the challenges of tomorrow?

description: Οι αγγειακές ανωμαλίες αποτελούν μια από τις πιο συχνές παθήσεις σε παιδιά και ενήλικες και περιλαμβάνουν μια ευρεία ομάδα παθήσεων. Λόγω των κοινών κλινικών και ιστοπαθολογικών τους χαρακτηριστικών για χρόνια δεν υπήρχε σαφής ταξινόμησή τους, μέχρι το 1982 που οι Mulliken και Glowacki καθιέρωσαν το διαχωρισμό σε αγγειακούς όγκους και αγγειακές δυσπλασίες, μια ταξινόμηση που υιοθετήθηκε από την παγκόσμια επιστημονική κοινότητα. Το πρόσωπο και ο τράχηλος αποτελούν από τις συχνότερες εντοπίσεις και ανάλογα με το είδος της βλάβης προσαρμόζεται και το πλάνο αντιμετώπισης. Σκοπός της παρούσας πτυχιακής εργασίας είναι η παρουσίαση των συχνότερων αγγειακών ανωμαλιών που αφορούν το έξω ους και τον έξω ακουστικό πόρο, ανατομικές περιοχές που δεν αποτελούν συχνά σημεία εντόπισης. Πιο συγκεκριμένα θα παρουσιαστούν τα αποτελέσματα που προέκυψαν από την συστηματική ανασκόπηση της βιβλιογραφίας από το 1982 έως σήμερα και αφορούν το είδος των βλαβών, την επιδημιολογία, τους τρόπους αντιμετώπισης και την εξέλιξή τους σε βάθος χρόνου. Τέλος, θα γίνει ανάλυση των παραπάνω αποτελεσμάτων, θα εξαχθούν συμπεράσματα και θα τεθούν μελλοντικά ερευνητικά ερωτήματα.
description: Vascular anomalies are one of the most common problems in children and adults and include a wide spectrum of different conditions. Due to their common clinical and histopathological features for many years their classification was not clear, until 1982 when Mulliken and Glowacki established two main categories, vascular tumors and vascular malformations. This classification is still adopted by the world scientific community. Face and neck are among the most frequent locations and the treatment plan is adapted according to the type of damage. Aim of this thesis is to present the most frequent vascular anomalies that concern two anatomical areas not often identified, the external ear and the external auditory canal. More specifically, the results of the systematic review of the literature from 1982 until today will be presented, focusing on the treatment methods and their evolution over time. The above-mentioned results will be analyzed, conclusions will be drawn and possible future research questions will be posed.
