description: The physics and computational prediction of turbulent boundary layer flow over axisymmetric and three-dimensional bodies are examined. Three cases were considered for which extensive experimental results and companion Reynolds-averaged Navier Stokes (RANS) solutions were obtained and/or available in the open literature. These cases all have Reynolds numbers based upon the freestream velocity and body geometric scale on the order of 105 to 106, which is large for laboratory scales but small compared to the maximum scales observed for full-scale vehicles. Despite significant differences in approach flow fields and geometries for these three cases, some common themes emerged in the findings. All cases involved complications due to pressure gradients combined with streamwise curvature, and all exhibited regions of turbulence reduction due to accelerated flow. These complications led to discrepancies in computed results even in attached flow regions where it is often assumed that RANS models provide reliable predictions. The authors recommend further work on modelling approaches that can capture rapid distortion effects on turbulence transport that can be incorporated into industry-useful frameworks. Two cases involving laterally symmetric, three-dimensional wall-mounted hills with aft-body separation revealed that asymmetric mean flow fields are likely to result. This finding has been observed in experiments conducted in multiple facilities and in computations using multiple solvers and turbulence models. It is concluded that non-unique and asymmetric global flow solutions are fundamental to flow cases with lateral geometric symmetry involving turbulent boundary layer separation. Further work is also needed to accurately predict low-frequency unsteadiness due to geometries that produce non-unique mean flow fields. For such flows, it remains to be definitively determined whether experimentally observed modes of the mean flow are equivalent, or nearly equivalent, to asymmetric mean flow solutions obtained using RANS approaches.

description: In this note we discuss the main results of a study of a massive binary with unequal mass ratio, q, embedded in an accretion disk, with its orbital rotation being opposed to that of the disk. When the mass ratio is sufficiently large, a gap opens in the disk, but the mechanism of gap formation is very different from the prograde case. Inward migration occurs on a timescale of t_ev ~ M_p/(dot M), where M_p is the mass of the less massive component (the perturber), and dot M is the accretion rate. When q<< 1, the accretion takes place mostly onto the more massive component, with the accretion rate onto the perturber being smaller than, or of order of, q^(1/3)M. However, this rate increases when supermassive binary black holes are considered and gravitational wave emission is important. We estimate a typical duration of time for which the accretion onto the perturber and gravitational waves could be detected.

description: Digital watermarking is a preliminary task of ingraining data into digital forms such as visual , audio-visual as well as audible data which helps to identify possessorship of those data. This technique is useful for copyright protection, tamper-resistant, theft-intimidation etc. it should be fixed in such a way that naked eye cannot bring into the mind & hard to eliminate, as growth of technologies in the digital side is becoming wider and wider chances of clone copies is added. The trending research field in current times is ensuring the penetration of data so that minor party cannot hold it. This paper covers an algorithm for black and white (binary) digital image watermarking mechanism based upon discrete wavelet transform, singular value decomposition and DCST. In this proposed watermarking algorithm, the proprietory image is compressed in the beginning and then watermarking process is carried out. The required bandwidth and storage capacity for image data will be reduced during transmission due to the applied compression before watermarking. The sturdiness of both host image as well as watermark image is tested along with DCST using respective performance measures. Finally, the performance of DCST based watermarking implementation has been compared with existing algorithm based on DOST. Comparative analysis has been carried out in presence of white Gaussian noise attack. The results show that, the performance and achievements of the presented algorithm is superior in comparison to the extant DOST based algorithm.
Onset of transverse instabilities of confined dark solitons

description: We investigate propagating dark soliton solutions of the two-dimensional defocusing nonlinear Schrödinger / Gross-Pitaevskii (NLS/GP) equation that are transversely confined to propagate in an infinitely long channel. Families of single, vortex, and multi-lobed solitons are computed using a spectrally-accurate numerical scheme. The multi-lobed solitons are unstable to small transverse perturbations. However, the single-lobed solitons are stable if they are sufficiently confined along the transverse direction, which explains their effective one-dimensional dynamics. The emergence of a transverse modulational instability is characterized in terms of a spectral bifurcation. The critical confinement width for this bifurcation is found to coincide with the existence of a propagating vortex solution and the onset of a "snaking" instability in the dark soliton dynamics that, in turn, give rise to vortex or multi-vortex excitations. These results shed light on the superfluidic hydrodynamics of dispersive shock waves in Bose-Einstein condensates and nonlinear optics.

description: The zero-temperature, classical $XY$-model on an $L \times L$ square-lattice is studied by exploring the distribution $Φ_L(y)$ of its centered and normalized magnetization $y$ in the large $L$ limit. An integral representation of the cumulant generating function, known from earlier works, is used for the numerical evaluation of $Φ_L(y)$, and the limit distribution $Φ_{L \rightarrow \infty} (y) = Φ_0(y)$ is obtained with high precision. The two leading finite-size corrections $Φ_L (y) -Φ_0 (y) \approx a_1(L)\, Φ_1(y) + a_2(L)\,Φ_2(y)$ are also extracted both from numerics and from analytic calculations. We find that the amplitude $a_1(L)$ scales as $\ln(L/L_0) /L^2$ and the shape correction function $Φ_1 (y)$ can be expressed through the low-order derivatives of the limit distribution, $Φ_1 (y) = [\,y\, Φ_0 (y) + Φ'_0 (y)\,]'$. The second finite-size correction has an amplitude $a_2(L)\propto 1/L^2$ and one finds that $a_2\,Φ_2(y) \ll a_1 \,Φ_1(y)$ already for small system size ($L> 10$). We illustrate the feasibility of observing the calculated finite-size corrections by performing simulations of the $XY$-model at low temperatures, including $T = 0$.

description: In this thesis we introduce a numerical approach adapted to the minimization of the first eigenvalue of the Laplacian with respect to the Dirichlet boundary condition on a polygonal domain of fixed area. We utilize the method of fundamental solutions and a standard descent method to optimize the first eigenvalue with respect to the vertices of the domain. This algorithm enables us to study the validity of the Polya-Szego conjecture for polygons with five or more sides, which has remained open since 1950. We also prove some properties of the Dirichlet eigenvalues when we have a polygonal domain.

description: A wide range of organisms features molecular machines, circadian clocks, which generate endogenous oscillations with ~24 h periodicity and thereby synchronize biological processes to diurnal environmental fluctuations. Recently, it has become clear that plants harbor more complex gene regulatory circuits within the core circadian clocks than other organisms, inspiring a fundamental question: are all these regulatory interactions between clock genes equally crucial for the establishment and maintenance of circadian rhythms? Our mechanistic simulation for Arabidopsis thaliana demonstrates that at least half of the total regulatory interactions must be present to express the circadian molecular profiles observed in wild-type plants. A set of those essential interactions is called herein a kernel of the circadian system. The kernel structure unbiasedly reveals four interlocked negative feedback loops contributing to circadian rhythms, and three feedback loops among them drive the autonomous oscillation itself. Strikingly, the kernel structure, as well as the whole clock circuitry, is overwhelmingly composed of inhibitory, rather than activating, interactions between genes. We found that this tendency underlies plant circadian molecular profiles which often exhibit sharply-shaped, cuspidate waveforms. Through the generation of these cuspidate profiles, inhibitory interactions may facilitate the global coordination of temporally-distant clock events that are markedly peaked at very specific times of day. Our systematic approach resulting in experimentally-testable predictions provides insights into a design principle of biological clockwork, with implications for synthetic biology.

title: Correlates of Knowledge and Locus of Control on Burden in Professional Caregivers of Alzheimer's Disease Victims in Three Institution Types
Creators: name: Manning-Gay, Ruth A.
Publisher: name: Old Dominion University Libraries
Year: 1985

description: In assessing professional caregivers of Alzheimer's Disease victims, this study tested whether, 1) knowledge would influence perceptions of burden in providing care to such patients, and if 2) individual locus of control would influence perceptions of burden in caring for; Alzheimer's I patients. Professional nurses (BSN's, RN's, and LPN's) from nursing banes, hospitals and psychiatric facilities were asked to complete a three part survey. Three instruments were utilized in this study: the Burden Self-Interview by Zarit, Reeves and Bach-Peterson and adapted for professional caregivers, a 15 item knowledge quiz and the North Carolina Internal External scale (short form) by Schopler, Lanqmeyer, Stokols and Reisman (1983). A total of 134 participants completed the study. Findings included, 1) Knowledge of the disease process was not significantly related to nurses perceptions of burden in caring for Alzheimer's patients and 2) Locus of control was significantly related to nurses perceptions of burden in caring for Alzheimer's patients. The study has implications for more in depth research. '!he findings failed to provide support for educational training on clinical aspects of Alzheimer's disease as a tool for impacting on a sense of burden. The findings related to Locus of Control however, indicate that instruction of nurses on the management of Alzheimer's patients, as well as techniques for altering nurses personal responses to difficult behavior may be an effective training strategy.
Pressure-induced phonon freezing in the ZnSeS II-VI mixed crystal: phonon-polaritons and ab initio calculations

description: Near-forward Raman scattering combined with ab initio phonon and bond length calculations is used to study the phonon-polariton transverse optical modes (with mixed electrical and mechanical character) of the II-VI ZnSeS mixed crystal under pressure. The goal of the study is to determine the pressure dependence of the poorly resolved percolation-type Zn-S Raman doublet of the three oscillator [1(Zn-Se),2(Zn-S)] ZnSe68S32 mixed crystal, which exhibits a phase transition at approximately the same pressure as its two end compounds (~14 GPa, zincblende-to-rocksalt), as determined by high-pressure x-ray diffraction. We find that the intensity of the lower Zn-S sub-mode of ZnSe68S32, due to Zn-S bonds vibrating in their own (S-like) environment, decreases under pressure (Raman scattering), whereas its frequency progressively converges onto that of the upper Zn- S sub-mode, due to Zn-S vibrations in the foreign (Se-like) environment (ab initio calculations). Ultimately, only the latter sub-mode survives. A similar phonon freezing was earlier evidenced with the well-resolved percolation-type Be-Se doublet of ZnBeSe [Pradhan et al. Phys. Rev. B 81, 115207 (2010)], that exhibits a large contrast in the pressure-induced structural transitions of its end compounds. We deduce that the above collapse and convergence process is intrinsic to the percolation doublet of a short bond under pressure, at least in a ZnSe-based mixed crystal, and not due to any pressure-induced structural transition.

title: Protecting Data Communication for the Next Generation Electric Vehicles
Creators: name: Zelle, Daniel
Publisher: name: UNSPECIFIED

description: This dissertation focuses on the cybersecurity of modern electric vehicles (EVs), specifically their communication protocols. The research highlights IT security risks, such as the manipulation of driving behavior, data breaches during the charging process, and threats to the stability of the power grid from EV charging.
A threat and risk analysis (TARA) is conducted to identify the critical points of attack in vehicle communication. We present an innovative approach to automating the assessment of the attack surface, which will accelerate the TARA process and reduce errors. The assessment reveals high risks in internal vehicle communication as well as in charging communication.
To secure internal communication via the CAN bus, we propose the BusCount protocol as a secure communication solution for protecting automotive networks. This approach provides clear advantages over existing solutions in protecting against replay and delay attacks.
Furthermore, we investigate securing modern automotive Ethernet using TLS and validate various communication scenarios. We assess the potential performance impacts of different ciphers on typical automotive hardware and compare them to the industry’s requirements. Security gaps were identified in the widespread SOME/IP protocol in service-oriented communication via automotive Ethernet. We developed two possible protocol extensions to secure SOME/IP.
This work also addresses potential manipulation of the power grid and data protection issues during the charging process to ensure the security of the EV charging infrastructure.
We show how to reduce the transmission of personal data during the charging process and propose an extension for the existing Plug & Charge protocols. Our proposed solution utilizes a Direct Anonymous Attestation (DAA) scheme for anonymous charging.
In summary, this work contributes to advancing EV cybersecurity by identifying critical aspects through a risk assessment and proposing ways to secure internal Controller Area Network (CAN) and automotive Ethernet communication. Additionally, this work addresses security and privacy issues related to the EV charging infrastructure. These findings and solutions provide a solid foundation for creating a more secure environment for EVs in the rapidly evolving automotive industry.

description: Collective and directed motility or swarming is an emergent phenomenon displayed by many self-organized assemblies of active biological matter such as clusters of embryonic cells during tissue development, cancerous cells during tumor formation and metastasis, colonies of bacteria in a biofilm, or even flocks of birds and schools of fish at the macro-scale. Such clusters typically encounter very heterogeneous environments. What happens when a cluster encounters an interface between two different environments has implications for its function and fate. Here we study this problem by using a mathematical model of a cluster that treats it as a single cohesive unit that moves in two dimensions by exerting a force/torque per unit area whose magnitude depends on the nature of the local environment. We find that low speed (overdamped) clusters encountering an interface with a moderate difference in properties can lead to refraction or even total internal reflection of the cluster. For large speeds (underdamped), where inertia dominates, the clusters show more complex behaviors crossing the interface multiple times and deviating from the predictable refraction and reflection for the low velocity clusters. We then present an extreme limit of the model in the absense of rotational damping where clusters can become stuck spiraling along the interface or move in large circular trajectories after leaving the interface. Our results show a wide range of behaviors that occur when collectively moving active biological matter moves across interfaces and these insights can be used to control motion by patterning environments.

Improving antibiotic stewardship in an urgent care setting through provider education
Creators: name: Delp, Rachel
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: Patients who present to urgent care centers (UCC) with upper respiratory infection (URI) complaints often receive antibiotics. This is not required because the symptoms are predominantly viral rather than bacterial. The practice of overprescribing antibiotics has significantly contributed to antibiotic-resistant organisms and unnecessary associated patient risk. The project’s purpose was to assess if a UCC healthcare provider (HCP) specific antibiotic stewardship program (ASP) educational intervention would decrease the number of antibiotic prescriptions written for URI complaints. Methodology: A quasi-experimental design was used to assess if an ASP educational intervention impacted the UCC’s HCP antibiotic prescribing decision for those with URI symptoms. During the pre-intervention phase, data was collected from the electronic medical record for patients presenting to the UCC with URI complaints during September and October 2021. At the August 2022 HCP staff meeting an educational PowerPoint was given on the importance of decreasing the prescribing rates of antibiotics for URIs through antibiotic stewardship. The post-intervention phase occurred during September and October 2022. Results: Prior to the implementation of the ASP, 13.44% of patients received antibiotics for URI symptoms. Post-implementation, 2.19% were prescribed an antibiotic. A chi-square test of independence showed that there was a significant difference between the two groups, χ2 (1, N = 640) = 28.12, p < .001. Implications for Practice: The results from this project indicate that the educational ASP intervention helped reduce unnecessary antibiotic prescribing for those with URI complaints.

description: During the last decades, the global prevalence of dengue progressed dramatically. It is a disease that is now endemic in more than one hundred countries of Africa, America, Asia, and the Western Pacific. In this paper, we present a mathematical model for the dengue disease transmission described by a system of ordinary differential equations and propose a multiobjective approach to find the most effective ways of controlling the disease. We use evolutionary multiobjective optimization (EMO) algorithms to solve the resulting optimization problem, providing the performance comparison of different algorithms. The obtained results show that the multiobjective approach is an effective tool to solve the problem, giving higher quality and wider range of solutions compared to the traditional technique. The obtained trade-offs provide a valuable information about the dynamics of infection transmissions and can be used as an input in the process of planning the intervention measures by the health authorities. Additionally, a suggested hybrid EMO algorithm produces highly superior performance compared to five other state-of-the-art EMO algorithms, being indispensable to efficiently optimize the proposed model.

description: La investigación que precede al presente artículo parte de dos aspectos esenciales para la crítica y estudios de la literatura femenina contemporáneas: la pregunta por la existencia de una literatura escrita por mujeres, con referencia particular aquí al Caribe colombiano, y por otra parte, el interés por las imágenes que en esta literatura se proyectan sobre la mujer en relación con el contexto sociohistórico de una determinada época, desde los años sesenta hasta los ochenta, en el caso de las escritoras caribeñas en Colombia.

description: Η συγκεκριμένη μελέτη ασχολείται με την καταγραφή των ιερών ναών, παρεκκλησιών και εξωκλησιών της νήσου Μυκόνου. Παρουσιάζω κατά το δυνατόν μια λεπτομερή καταγραφή των ενοριών που βρίσκονται εντός της πόλεως και των 2 ιερών μονών που ανευρίσκουμε στην Άνω Μερά του νησιού ,εκτός της πόλεως και συγκεκριμένα στο ανατολικό τμήμα της. Ειδικά γίνεται αναφορά στην ονομασία των ιερών ναών, το έτος ανοικοδομήσεως, τους κτήτορες αυτών και την λεπτομερή περιγραφή εντός και εκτός αυτών. Το νησί της Μυκόνου διαφυλάττει την κυκλαδίτικη αρχιτεκτονική παράδοση και τεχνοτροπία μέχρι σήμερον και παρουσιάζει μια ιδιότυπη πολιτισμική αμφισημία. Πορεύεται και συμπορεύεται στον σύγχρονο κόσμο όπως πολλές άλλες κοσμοπολίτικες πόλεις ανά τον κόσμο δίχως όμως να έχει απωλέσει τα ιδιαίτερα κοινωνικό-θρησκευτικά χαρακτηριστικά της.
description: This specific study deals with the recording of the holy temples, small chapels and countryside chapels of the island of Mykonos. I present, as far as possible, a detailed record of the parishes located within the city and of the 2 holy monasteries that we find in the Upper part (Ano Mera) of the island, outside the city and specifically in its eastern part. Special reference is made to the name of the holy temples, the year of reconstruction, their founders and the detailed description inside and outside them. The island of Mykonos preserves the Cycladic architectural tradition and style to this day and presents a unique cultural ambiguity. It moves and adapts to the modern world like many other cosmopolitan cities around the world without, however, having lost its special socio-religious characteristics.

description: Η παρούσα διπλωματική εργασία έχει ως αντικείμενο μελέτης τη θέση των δημοσιογράφων του πολιτισμού, οι οποίοι δραστηριοποιούνται στα ελληνικά έντυπα και ηλεκτρονικά μέσα ενημέρωσης κατά τον 21ο αιώνα, καλύπτοντας ποικίλα είδη τέχνης. Εξετάζονται η φυσιογνωμία και οι ιδιαιτερότητες των λειτουργών του εν λόγω κλάδου σε σχέση με άλλες δημοσιογραφικές ειδικότητες, μελετώνται ο ρόλος τους και οι πρακτικές που ακολουθούν κατά την άσκηση των καθηκόντων τους, ενώ παράλληλα διερευνάται πώς αντιλαμβάνονται οι ίδιοι τον εαυτό τους και τι πιστεύουν για το έργο που επιτελούν. Η ερευνητική μέθοδος που χρησιμοποιήθηκε είναι οι ημιδομημένες συνεντεύξεις με μάχιμους δημοσιογράφους του χώρου, και για την επεξεργασία των δεδομένων που συγκεντρώθηκαν ακολούθησε ανάλυση περιεχομένου σε συνδυασμό με στοιχεία ανάλυσης λόγου.
description: The present dissertation elaborates on the status of cultural journalists active with the Greek print and digital media, covering various types of art, during the 21st century. It examines the general appearance and peculiarities of this branch’s functionaries in relation to other journalistic specialties and studies their role and practices followed upon exercising their work tasks, while elaborating on their self-perception and thoughts about their work. The research method applied is that of semi-structured interviews with journalists active in this field, along with a content analysis combined with certain elements of discourse analysis for the processing of the collected data.

Distribution and mass of diffuse and dense CO gas in the Milky Way

description: Emission from carbon monoxide (CO) is ubiquitously used as a tracer of dense star forming molecular clouds. There is, however, growing evidence that a significant fraction of CO emission originates from diffuse molecular gas. Quantifying the contribution of diffuse CO-emitting gas is vital for understanding the relation between molecular gas and star formation. We examine the Galactic distribution of two CO-emitting gas components, a high column density component detected in 13CO and 12CO, and a low column density component detected in 12CO, but not in 13CO. The "diffuse" and "dense" components are identified using a combination of smoothing, masking, and erosion/dilation procedures, making use of three large-scale 12CO and 13CO surveys of the Inner and Outer Milky Way. The diffuse component, which globally represents 25 (1.5x1e8 Mo) of the total molecular gas mass (6.5x1e8 Mo), is more extended perpendicular to the Galactic plane. The fraction of diffuse gas increases from 15% at a galactocentric radius of 3 kpc to 50% at 15 kpc, and increases with decreasing surface density. In the Inner Galaxy, a yet denser component traced by CS emission represents 14% of the total molecular gas mass traced by 12CO emission. Only 14% of the molecular gas mass traced by 12CO emission is identified as part of molecular clouds in 12CO surveys by cloud identification algorithms. This study indicates that CO emission not only traces star forming clouds, but also a significant diffuse molecular ISM component.
