description: This paper presents a game theoretic framework for participation and free-riding in federated learning (FL), and determines the Nash equilibrium strategies when FL is executed over wireless links. To support spectrum sensing for NextG communications, FL is used by clients, namely spectrum sensors with limited training datasets and computation resources, to train a wireless signal classifier while preserving privacy. In FL, a client may be free-riding, i.e., it does not participate in FL model updates, if the computation and transmission cost for FL participation is high, and receives the global model (learned by other clients) without incurring a cost. However, the free-riding behavior may potentially decrease the global accuracy due to lack of contribution to global model learning. This tradeoff leads to a non-cooperative game where each client aims to individually maximize its utility as the difference between the global model accuracy and the cost of FL participation. The Nash equilibrium strategies are derived for free-riding probabilities such that no client can unilaterally increase its utility given the strategies of its opponents remain the same. The free-riding probability increases with the FL participation cost and the number of clients, and a significant optimality gap exists in Nash equilibrium with respect to the joint optimization for all clients. The optimality gap increases with the number of clients and the maximum gap is evaluated as a function of the cost. These results quantify the impact of free-riding on the resilience of FL in NextG networks and indicate operational modes for FL participation.

description: An important goal in nanoelectromechanics is to cool the vibrational motion, ideally to its quantum ground state. Cooling by an applied charge current is a particularly simple and hence attractive strategy to this effect. Here, we explore this phenomenon in the context of the general theory of thermoelectrics. In linear response, this theory describes thermoelectric refrigerators in terms of their cooling efficiency and figure of merit ZT. We show that both concepts carry over to phonon cooling in nanoelectromechanical systems. As an important consequence, this allows us to discuss the efficiency of phonon refrigerators in relation to the fundamental Carnot efficiency. We illustrate these general concepts by thoroughly investigating a simple double-quantum-dot model with the dual advantage of being quite realistic experimentally and amenable to a largely analytical analysis theoretically. Specifically, we obtain results for the efficiency, the figure of merit, and the effective temperature of the vibrational motion in two regimes. In the quantum regime in which the vibrational motion is fast compared to the electronic degrees of freedom, we can describe the electronic and phononic dynamics of the model in terms of master equations. In the complementary classical regime of slow vibrational motion, the dynamics is described in terms of an appropriate Langevin equation. Remarkably, we find that the efficiency can approach the maximal Carnot value in the quantum regime, with large associated figures of merit. In contrast, the efficiencies are typically far from the Carnot limit in the classical regime. Our theoretical results should provide guidance to implementing efficient vibrational cooling of nanoelectromechanical systems in the laboratory.

Revealing the substrate origin of the linear dispersion of silicene/Ag(111)

description: The band structure of the recently synthesized (3$\times$3) silicene monolayer on (4$\times$4) Ag(111) is investigated using density functional theory. A $k$-projection technique that includes the $k_\bot$-dependence of the surface bands is used to separate the contributions arising from the silicene and the substrate, allowing a consistent comparison between the calculations and the angle-resolved photoemission experiments. Our calculations not only reproduce the observed gap and linear dispersion across the K point of (1$\times$1) silicene, but also demonstrate that these originate from the $k_\bot$-dependence of Ag(111) substrate states (modified by interactions with the silicene) and \textit{not} from a Dirac state.

description: We report on empirical trends between the dynamically determined stellar initial mass function (IMF) and stellar population properties for a complete, volume-limited sample of 260 early-type galaxies from the Atlas3D project. We study trends between our dynamically-derived IMF normalisation and absorption line strengths, and interpret these via single stellar population- (SSP-) equivalent ages, abundance ratios (measured as [alpha/Fe]), and total metallicity, [Z/H]. We find that old and alpha-enhanced galaxies tend to have on average heavier (Salpeter-like) mass normalisation of the IMF, but stellar population does not appear to be a good predictor of the IMF, with a large range of normalisation at a given population parameter. As a result, we find weak IMF-[alpha/Fe] and IMF-age correlations, and no significant IMF-[Z/H] correlation. The observed trends appear significantly weaker than those reported in studies that measure the IMF normalisation via low-mass star demographics inferred through stellar spectral analysis.

title: An Investigation of Software Reliability Models
Creators: name: Bowman, Pamela Elaine
Publisher: name: Old Dominion University Libraries
Year: 1996

description: Many software reliability models have been promoted in the literature in an attempt to provide a meaningful response to the growing need to know the reliability of software during and after the development process. However, there are well-founded concerns as to the accuracy of the individual model, as well as to the choice of which model to use for a particular program. A recent experiment based on the debugging history of a partially debugged program used a gold version to label a debugging graph from replicated data. This experiment concluded that presenting the replicated data to the models in a way that approximated a debugging session with the largest bugs found first allowed the Logarithmic Poisson model to make highly accurate predictions for the program in question. The experiment also showed that in the absence of a gold program a surrogate can be created by using the program with all known fixes installed. The contribution of this thesis is fourfold. First, the results of the previous experiment are corroborated on a different program written to the same specifications. Second, an approximation technique which uses the deltas or differences between two versions of the program to approximate the reliability change between those versions is shown to be a viable alternative to the gold or surrogate gold techniques. Third, the data variation due to the random input generation process is investigated and shown to not have a significant effect on the results of these experiments. Fourth, implementation schemes are presented for using the surrogate gold and delta techniques in a software development environment and are shown to produce accurate predictions for the program in this experiment.

description: The deployment flexibility and maneuverability of Unmanned Aerial Vehicles (UAVs) increased their adoption in various applications, such as wildfire tracking, border monitoring, etc. In many critical applications, UAVs capture images and other sensory data and then send the captured data to remote servers for inference and data processing tasks. However, this approach is not always practical in real-time applications due to the connection instability, limited bandwidth, and end-to-end latency. One promising solution is to divide the inference requests into multiple parts (layers or segments), with each part being executed in a different UAV based on the available resources. Furthermore, some applications require the UAVs to traverse certain areas and capture incidents; thus, planning their paths becomes critical particularly, to reduce the latency of making the collaborative inference process. Specifically, planning the UAVs trajectory can reduce the data transmission latency by communicating with devices in the same proximity while mitigating the transmission interference. This work aims to design a model for distributed collaborative inference requests and path planning in a UAV swarm while respecting the resource constraints due to the computational load and memory usage of the inference requests. The model is formulated as an optimization problem and aims to minimize latency. The formulated problem is NP-hard so finding the optimal solution is quite complex; thus, this paper introduces a real-time and dynamic solution for online applications using deep reinforcement learning. We conduct extensive simulations and compare our results to the-state-of-the-art studies demonstrating that our model outperforms the competing models.

description: The present study analyses the use of vague quantifiers in spoken Italian and German. Vague quantifiers are linguistic expressions through which speakers approximately or imprecisely quantify, estimate and approximate numerical values. Chapter I recalls the main contemporary studies on linguistic vagueness in spoken language, with a focus on the concept of Intentional Vagueness. Chapter II deals with quantitative approximation and the studies that managed to observe the use of vague quantifiers in spoken language until now, in order to describe their functions, contexts of use and communicative effects. Chapter III describes the methodological choices made to analyse vague quantifiers in spoken Italian and German, i.e. the corpora chosen for each language and the criteria beyond the choices of the conversations and the labelling of linguistic forms that arose during the analysis. The chapter proceeds with the first quantitative data about the use of vague quantifiers and the conversational contexts in which they are more frequent. Finally, this chapter describes the causes and the effects of vague quantifiers in spoken conversations as well as the experiential domains that we more frequently tend to quantify through vague or approximate words. Chapter IV contains the analysis of the different types of quantification expressions that were grouped into seven different categories or types. The chapter describes the form and functions of vague quantifiers and gives quantitative information about the occurrences. This analysis also takes into account multiple expressions of vagueness and quantification, i.e. it describes those cases in which speakers use more than one strategy of quantification and vagueness in the same utterance, observing the type of relations among these different elements and whether or not they form clusters or behave like co-occurrences. In Chapter V, the concluding remarks are shown, focussing on the more relevant aspects of my analysis for both languages. [edited by Author]

description: We calculate statistical properties of amorphous polymer chains between crystalline lamellae by self-consistent field model simulations. In our model, an amorphous subchain is modelled as a polymer chain of which ends are grafted onto the crystal-amorphous interfaces. The crystal-amorphous interfaces are expressed as impenetrable surfaces. We incorporate the interaction between segments to satisfy the incompressible condition for the segment density field. The simulation results show that amorphous polymer chains feel thin potential layers, which are mainly repulsive, near the crystal-amorphous interfaces. The impenetrable and incompressible conditions affect the statistics of polymer chains and the chain statistics becomes qualitatively different from the ideal Gaussian chain statistics without any constraints. We show the effects of the system size and the graft density to statistical quantities. We also show that the tie subchain statistics obey rather simple statistics.

description: Error Correcting Codes are required to have a reliable communication through a medium that has an unacceptable bit error rate and low signal to noise ratio. In IEEE 802.15.6 2.4GHz Wireless Body Area Network (WBAN), data gets corrupted during the transmission and reception due to noises and interferences. Ultra low power operation is crucial to prolong the life of implantable devices. Hence simple block codes like BCH (63, 51, 2) can be employed in the transceiver design of 802.15.6 Narrowband PHY. In this paper, implementation of BCH (63, 51, t = 2) Encoder and Decoder using VHDL is discussed. The incoming 51 bits are encoded into 63 bit code word using (63, 51) BCH encoder. It can detect and correct up to 2 random errors. The design of an encoder is implemented using Linear Feed Back Shift Register (LFSR) for polynomial division and the decoder design is based on syndrome calculator, inversion-less Berlekamp-Massey algorithm (BMA) and Chien search algorithm. Synthesis and simulation were carried out using Xilinx ISE 14.2 and ModelSim 10.1c. The codes are implemented over Virtex 4 FPGA device and tested on DN8000K10PCIE Logic Emulation Board. To the best of our knowledge, it is the first time an implementation of (63, 51) BCH encoder and decoder carried out.

Publisher: name: Old Dominion University Libraries

description: Open source software development is credited as the basic fuel powering much of the Internet, especially the Web. While many organizations rely heavily on open source, few studies have focused on the dynamics of development methodology. This document contains the results of a longitudinal metric study of the open source database PostgreSQL representing an 8 year period of community development. This study is software archeology, excavating bits of an Internet community, a cultural group, for understanding. Longitudinally, McCabe's cyclomatic complexity and Halstead's software science change tempo in accordance with PostgreSQL's maturity, though meritocracy practices of open source might suggest greater divergence. Some have implied that open source development is inferior to commercial development, which implies statically significant varying metrics. The results of this study disagree with this assertion, since McCabe's, Halstead's, and KDSI show a stable progressive growth pattern and not unruly chaotic growth. In fact, as the code has nearly doubled through increased functionality, cyclomatic complexity has remained stable well within McCabe's recommended guidelines. There is also a high degree of correlation among McCabe's, Halstead's, and KDSI potentially yielding new metric equivalence insights.

description: A hypercomplex manifold $M$ is a manifold equipped with three complex structures satisfying quaternionic relations. Such a manifold admits a canonical torsion-free connection preserving the quaternion action, called Obata connection. A quaternionic Hermitian metric is a Riemannian metric on which is invariant with respect to unitary quaternions. Such a metric is called HKT if it is locally obtained as a Hessian of a function averaged with quaternions. HKT metric is a natural analogue of a Kahler metric on a complex manifold. We push this analogy further, proving a quaternionic analogue of Buchdahl-Lamari's theorem for complex surfaces. Buchdahl and Lamari have shown that a complex surface M admits a Kahler structure iff $b_1(M)$ is even. We show that a hypercomplex manifold M with Obata holonomy $SL(2,{\mathbb H})$ admits an HKT structure iff $H^{0,1}(M)=H^1({\cal O}_M)$ is even.

description: We present a general framework for the garment animation problem through unsupervised deep learning inspired in physically based simulation. Existing trends in the literature already explore this possibility. Nonetheless, these approaches do not handle cloth dynamics. Here, we propose the first methodology able to learn realistic cloth dynamics unsupervisedly, and henceforth, a general formulation for neural cloth simulation. The key to achieve this is to adapt an existing optimization scheme for motion from simulation based methodologies to deep learning. Then, analyzing the nature of the problem, we devise an architecture able to automatically disentangle static and dynamic cloth subspaces by design. We will show how this improves model performance. Additionally, this opens the possibility of a novel motion augmentation technique that greatly improves generalization. Finally, we show it also allows to control the level of motion in the predictions. This is a useful, never seen before, tool for artists. We provide of detailed analysis of the problem to establish the bases of neural cloth simulation and guide future research into the specifics of this domain.

description: We present the results of spectroscopic and photometric observations for three hot southern-hemisphere post-AGB objects, Hen 3-1347 = IRAS 17074-1845, Hen 3-1428 = IRAS17311-4924, and LSS 4634 = IRAS 18023-3409. In the spectrograms taken with the 1.9-m telescope of the South African Astronomical Observatory (SAAO) in 2012, we have measured the equivalent widths of the most prominent spectral lines. Comparison of the new data with those published previously points to a change in the spectra of Hen 3-1428 and LSS 4634 in the last 20 years. Based on ASAS data, we have detected rapid photometric variability in all three stars with an amplitude up to 0.3 mag, 0.4 mag in the $V$ band. A similarity between the patterns of variability for the sample stars and other hot protoplanetary nebulae is pointed out. We present the results of $UBV$ observations for Hen 3-1347, according to which the star undergoes rapid irregular brightness variations with maximum amplitudes $ΔV$=0.25 mag, $ΔB$=0.25 mag, and $ΔU$=0.30 mag and shows color-magnitude correlations. Based on archival data, we have traced the photometric history of the stars over more than 100 years. Hen 3-1347 and LSS 4634 have exhibited a significant fading on a long time scale. The revealed brightness and spectrum variations in the stars, along with evidence for their enhanced mass, may be indicative of their rapid post-AGB evolution.

title: Real Time Texture Analysis from the Parallel Computation of Fractal Dimension
Creators: name: Hayes Jr., Halford I.
Publisher: name: Old Dominion University Libraries
Year: 1993

description: The discrimination of texture features in an image has many important applications: from detection of man-made objects from a surrounding natural background to identification of cancerous from healthy tissue in X-ray imagery. The fractal structure in an image has been used with success to identify these features but requires unacceptable processing time if executed sequentially.

The paradigm of data parallelism is presented as the best method for applying massively parallel processing to the computation of fractal dimension of an image. With this methodology, and sufficient numbers of processors, this computation can reach real time speeds necessary for many applications. A model is analyzed and evaluated on several architectures: workstation, vectorizing supercomputer, shared-memory MIMD, and massively parallel SIMD computers. Per expectations, results in the subsecond range are attained on the massively parallel SIMD computer.

description: Nuclear spin imaging at the atomic level is essential for the understanding of fundamental biological phenomena and for applications such as drug discovery. The advent of novel nano-scale sensors has given hope of achieving the long-standing goal of single-protein, high spatial-resolution structure determination in their natural environment and ambient conditions. In particular, quantum sensors based on the spin-dependent photoluminescence of Nitrogen Vacancy (NV) centers in diamond have recently been used to detect nanoscale ensembles of external nuclear spins. While NV sensitivity is approaching single-spin levels, extracting relevant information from a very complex structure is a further challenge, since it requires not only the ability to sense the magnetic field of an isolated nuclear spin, but also to achieve atomic-scale spatial resolution. Here we propose a method that, by exploiting the coupling of the NV center to an intrinsic quantum memory associated with the Nitrogen nuclear spin, can reach a tenfold improvement in spatial resolution, down to atomic scales. The spatial resolution enhancement is achieved through coherent control of the sensor spin, which creates a dynamic frequency filter selecting only a few nuclear spins at a time. We propose and analyze a protocol that would allow not only sensing individual spins in a complex biomolecule, but also unraveling couplings among them, thus elucidating local characteristics of the molecule structure.

description: The concept of must testing is naturally parametrised with a chosen completeness criterion or fairness assumption. When taking weak fairness as used in I/O automata, I show that it characterises exactly the fair preorder on I/O automata as defined by Lynch & Tuttle.

description: The effect of quasi-resonance energy transfer in collisions between H$_2$ and H$_2$O molecules in H$_2$O maser sources is investigated. New data on the state-to-state rate coefficients for collisional transitions for H$_2$O and H$_2$ molecules are used in the calculations. The results of ortho-H$_2$O level population inversion calculations for the 22.2-, 380-, 439-, and 621-GHz transitions are presented. The ortho-H$_2$O level population inversion is shown to depend significantly on the population distribution of the para-H$_2$ $J = 0$ and $2$ rotational levels. The possibility of quasi-resonance energy transfer in collisions between H$_2$ molecules at highly excited rotational-vibrational levels and H$_2$O molecules is considered. The quasi-resonance energy transfer effect can play a significant role in pumping H$_2$O masers in the central regions of active galactic nuclei and in star-forming regions.

description: How does race and location shape the reproductive decisions of gay men who are intended parents? In this article, we propose the concept of strategic racialization to characterize the ways in which gay male parents employ racial matching in their selection of egg donors and surrogates in the United States and United Kingdom. We argue that racial matching is a strategy of stigma management. This study draws upon interview data from 40 gay male couples who formed families through surrogacy. We find that pre-conception fathers seek racialized resemblance to reinforce kinship between themselves and their children. In California and England, gay men seeking donor eggs engage in racial matching, which reveals that the racialized biogenetic model of kinship remains dominant. This study makes a significant contribution to the literature on race and queer family formation.
Lessons from LHC elastic and diffractive data

description: In the light of LHC data, we discuss the global description of all high energy elastic and diffractive data, using a one-pomeron model, but including multi-pomeron interactions. The LHC data indicate the need of a $k_t(s)$ behaviour, where $k_t$ is the gluon transverse momentum along the partonic ladder structure which describes the pomeron. We also discuss tensions in the data, as well as the $t$ dependence of the slope of $dσ_{el}/dt$ in the small $t$ domain.

description: Theoretical studies of the nucleosynthesis origin of the heavy elements in our Solar System (S.S.) by the rapid neutron-capture process (r-process) still face the entwined uncertainties in the possible astrophysical scenarios and the nuclear-physics properties far from stability. In this paper we present results from the investigation of an r-process in the high-entropy wind (HEW) of core-collapse supernovae (here chosen as one of the possible scenarios for this nucleosynthesis process), using new nuclear-data input calculated in a consistent approach, for masses and $β$-decay properties from the new finite-range droplet model FRDM(2012). The accuracy of the new mass model is 0.56 MeV with respect to {\sc AME2003}, to which it was adjusted. We compare the new HEW r-process abundance pattern to the latest S.S. r-process residuals and to our earlier calculations with the nuclear-structure quantities based on FRDM(1992). Substantial overall and specific local improvements in the calculated pattern of the r-process between $A\simeq 110$ and $^{209}$Bi, as well as remaining deficiencies are discussed in terms of the underlying spherical and deformed shell structure far from stability.

description: We begin here a series of papers examining the chromospheric and coronal properties of solar active regions. This first paper describes an extensive dataset of images from the Atmospheric Imaging Assembly on the Solar Dynamics Observatory curated for large-sample analysis of this topic. Based on (and constructed to coordinate with) the ``Active Region Patches'' as identified by the pipeline data analysis system for the Helioseismic and Magnetic Imager (HMI) on the same mission, the ``HARPs''), the ``AIA Active Region Patches'' (AARPs), described herein, comprise an unbiased multi-wavelength set of FITS files downsampled spatially only by way of HARP-centered patch extractions (full spatial sampling is retained), and downsampled in the temporal domain but still able to describe both short-lived kinematics and longer-term trends. The AARPs database enables physics-informed parametrization and analysis using Nonparametric Discriminant Analysis in Paper II of this series, and is validated for analysis using Differential Emission Measure techniques. The AARP dataset presently covers mid-2010 through December 2018, is approx 9TB in size, and available through the Solar Data Analysis Center.
