description: Abstract: X-ray Tomography is one of the well-known non-destructive methods for investigating the internal features of 3D objects. In Materials Science, this method is used for studying the internal defects, inclusions, microstructure, etc., of manufactured parts without cutting them. The images can be stacked together and reconstruct a digital version of the sample with all the details. An experienced person usually segments each image manually to identify the internal features, which is time-consuming and cumbersome. In recent years, AI has been employed for identifying those features after training with limited manually segmented images. Due to the enormous amount of data produced by imaging instruments and the everyday-growing number of AI architectures for image segmentation, the raw and processed data management and their relationship are challenging. This research proposes a database management system to control the tomography datasets and the AI architectures used for segmenting them

description: We formulate the control of reactive power generation by photovoltaic inverters in a power distribution circuit as a constrained optimization that aims to minimize reactive power losses subject to finite inverter capacity and upper and lower voltage limits at all nodes in the circuit. When voltage variations along the circuit are small and losses of both real and reactive powers are small compared to the respective flows, the resulting optimization problem is convex. Moreover, the cost function is separable enabling a distributed, on-line implementation with node-local computations using only local measurements augmented with limited information from the neighboring nodes communicated over cyber channels. Such an approach lies between the fully centralized and local policy approaches previously considered. We explore protocols based on the dual ascent method and on the Alternating Direction Method of Multipliers (ADMM) and find that the ADMM protocol performs significantly better.

description: Recently, the stochastic dynamical model based on the free energy landscape was proposed to quantify the kinetics of the black hole phase transition. An essential concept is the generalized free energy of the fluctuating black hole, which was defined in terms of the thermodynamic relation previously. In this work, by employing the Gibbons-Hawking path integral approach to black hole thermodynamics, we show that the generalized free energy can be derived from the Einstein-Hilbert action of the Euclidean gravitational instanton with the conical singularity. This work provides a concrete and solid foundation for the free energy landscape formalism of black hole phase transition.

description: We propose a novel experiment, the Canfranc Axion Detection Experiment (CADEx), to probe dark matter axions with masses in the range 330-460 $μ$eV, within the W-band (80-110 GHz), an unexplored parameter space in the well-motivated dark matter window of Quantum ChromoDynamics (QCD) axions. The experimental design consists of a microwave resonant cavity haloscope in a high static magnetic field coupled to a highly sensitive detecting system based on Kinetic Inductance Detectors via optimized quasi-optics (horns and mirrors). The experiment is in preparation and will be installed in the dilution refrigerator of the Canfranc Underground Laboratory. Sensitivity forecasts for axion detection with CADEx, together with the potential of the experiment to search for dark photons, are presented.

A Unified Approach for Beam-Split Mitigation in Terahertz Wideband Hybrid Beamforming

description: The sixth generation networks envision the deployment of terahertz (THz) band as one of the key enabling property thanks to its abundant bandwidth. However, the ultra-wide bandwidth in THz causes beam-split phenomenon due to the use of a single analog beamformer (AB). Specifically, beam-split makes different subcarriers to observe distinct directions since the same AB is adopted for all subcarriers. Previous works mostly employ additional hardware components, e.g., time-delayer networks to mitigate beam-split by realizing virtual subcarrier-dependent ABs. This paper introduces an efficient and unified approach, called beam-split-aware (BSA) hybrid beamforming. In particular, instead of virtually generating subcarrier-dependent ABs, a single AB is used and the effect of beam-split is computed and passed into the digital beamformers, which are subcarrier-dependent while maximizing spectral efficiency. Hence, the proposed BSA approach effectively mitigates the impact of beam-split and it can be applied to any hybrid beamforming architecture. Manifold optimization and orthogonal matching pursuit techniques are considered for the evaluation of the proposed approach in multi-user scenario. Numerical simulations show that significant performance improvement can be achieved as compared to the conventional techniques.

The Paradox of Power Loss in a Lossless Infinite Transmission Line
Creators: name: Singal, Ashok K.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: We discuss here the famous paradox of a continuous power drainage from the source at the input of an otherwise lossless infinite transmission line. The solution of the paradox lies in the realization that in an open-circuit finite transmission line/ladder network, there is an incident as well as a reflected wave and the input impedence is determined by the superposition of both waves. It is explicitly shown that the reactive input impedance of even a single block, comprising say a simple LC circuit, is determined at all driving frequencies from the superposition of incident and reflected waves, and that the input impedance remains reactive in nature (i.e., an imaginary value) even when additional blocks are added indefinitely. However in a ladder network or transmission line, taken to be {\em infinite right from the beginning}, there is no reflected wave (assuming the circuit to be ideal with no discontinuities en route). Thus the source while continuously supplying power in the forward direction, does not retrieve it from a reflected wave and unlike in the case of a finite line, there is a net power loss. This apparently lost energy ultimately appears in the electromagnetic fields in the reactive elements (capacitances and inductances which to begin with had no such stored energy), further down the line as the incident wave advances forward. It is also shown that radiation plays absolutely no role in resolving this intriguing paradox.

The geometry of neural population activity during motor learning and memory
Creators: name: Losey, Darby
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Applied Computer Science

description: The human brain is a marvel of complexity, with billions of neurons and trillions
 of connections that allow us to perform an astounding array of behaviors, from basic
 movements like walking and grasping to complex cognitive processes like decision-
 making and language. However, despite decades of research, much about how the
 brain learns and remembers remains a mystery.
 One challenge in understanding the neural basis of learning and memory is that
 seemingly simple acts, like taking a sip of water, are in fact immensely complex
 processes that require an intricate coordination of neural activity. Yet humans are
 able to learn and remember how to perform a vast array of new skills, suggesting
 that the brain has the capacity to produce neural activity appropriate for a wide
 variety of tasks.
 To better understand how the brain learns and remembers new behaviors, it is
 important to investigate the interplay between learning and memory. However, this
 relationship is not well understood, and a better understanding of it could shed light
 on how the brain is able to learn new tasks without forgetting familiar ones.
 A difficulty in probing how the brain learns and remembers different tasks is that
 the relationship between neural activity and behavior is very complex and difficult to
 estimate. To circumvent this obstacle, we employ a brain-computer interface (BCI).
 A BCI allows the experimenters to specify the causal relationship between neural
 activity and behavior, which can provide insights into the underlying mechanisms of
 learning and memory. This is in contrast to traditional arm-reaching experiments,
 where the relationship between neural activity and behavior is largely unknown.
 The focus of this thesis is to explore the geometry of neural population activity
 during motor learning and memory. By leveraging the causal relationship between
 neural activity and behavior, we aim to shed light on the complex processes that
 underlie motor memories, and to provide insights into how the brain is able to learn
 and retain new behaviors. The pinnacle result of this thesis is that learning alters
 neural activity to simultaneously support both memory and action - i.e. learning
 leaves a “memory trace” in neural population activity.

description: In stark contrast to the conventional charge density wave (CDW) materials, the one-dimensional CDW on the In/Si(111) surface exhibits immediate damping of the CDW oscillation during the photoinduced phase transition. Here, by successfully reproducing the experimentally observed photoinduced CDW transition on the In/Si(111) surface by performing real-time time-dependent density functional theory (rt-TDDFT) simulations, we demonstrate that photoexcitation promotes valence electrons from Si substrate to empty surface bands composed primarily of the covalent p-p bonding states of the long In-In bonds, generating interatomic forces to shorten the long bonds and in turn drives coherently the structural transition. We illustrate that after the structural transition, the component of these surface bands occurs a switch among different covalent In bonds, causing a rotation of the interatomic forces by about π/6 and thus quickly damping the oscillations in feature CDW modes. These findings provide a deeper understanding of photoinduced phase transitions.

description: The imaginary Poynting momentum (IPM) of light has been captivated an unusual origin of optomechanical effects on dipolar magnetoelectric particles, but yet observed in experiments. Here, we report, for the very first time, a whole family of high-order IPM forces for not only magnetoelectric but also generic Mie particles, assisted with their excited higher multipoles within. Such optomechanical phenomena derive from a nonlinear contribution of the IPM to the optical force, and can be remarkable even when the incident IPM is small. We observe the high-order optomechanics in a structured light beam with vortex-like IPM streamlines, which allows the low-order dipolar contribution to be suppressed. Our results provide the first unambiguous evidence of the ponderomotive nature of the IPM, expand the classification of optical forces and open new possibilities for optical forces and micromanipulations.

description: There is a well-known analogy between statistical and quantum mechanics. In statistical mechanics, Boltzmann realized that the probability for a system in thermal equilibrium to occupy a given state is proportional to exp(-E/kT) where E is the energy of that state. In quantum mechanics, Feynman realized that the amplitude for a system to undergo a given history is proportional to exp(-S/i hbar) where S is the action of that history. In statistical mechanics we can recover Boltzmann's formula by maximizing entropy subject to a constraint on the expected energy. This raises the question: what is the quantum mechanical analogue of entropy? We give a formula for this quantity, which we call "quantropy". We recover Feynman's formula from assuming that histories have complex amplitudes, that these amplitudes sum to one, and that the amplitudes give a stationary point of quantropy subject to a constraint on the expected action. Alternatively, we can assume the amplitudes sum to one and that they give a stationary point of a quantity we call "free action", which is analogous to free energy in statistical mechanics. We compute the quantropy, expected action and free action for a free particle, and draw some conclusions from the results.

Cognitive processes and emotion cue processing in introvertive anhedonia

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Other psychology not elsewhere classified

description: Executive cognitive processes and emotion cue processing was explored in introvertive anhedonia, the O-LIFE’s negative schizotypal trait dimension, with the aim of identifying endophenotypes. The experimental work of the thesis was conducted in three distinct parts. The first two used reaction time tasks of selective attention to examine 1) the possibility of a general abnormality in executive cognitive functioning, and 2) the possibility of an emotion cue processing abnormality. Results from these two parts informed the development of the final experiment that used procedures adapted from animal associative learning to examine the interaction between executive cognitive processes and the processing of positive and negative emotional cues in 1) the learning of differentially reinforced biconditional discrimination and 2) the sensitivity to changes in the emotional valence of outcomes. Two experiments, presented in Chapter 2, established that introvertive anhedonia was associated with an executive functioning deficit that could be characterised as a deficiency in processing context. Chapter 3 presented a further three experiments indicating that introvertive anhedonia had blunted processing of negative and positive emotional cues, but under certain specific conditions a bias to the processing of negative stimuli. The final experiment, presented in Chapter 4, found that introvertive anhedonia was behaviourally insensitive to outcome valence changes of stimulus-outcome associations. The blunted processing of valenced stimuli seems to have influenced executive cognitive processes involved in both detecting the changes in outcome valence of associations and in forming new associations. An inability in introvertive anhedonia to adjust behaviour to changes in outcome valence might lead to perseveration, inappropriate responding and, in some situations, an over-exposure to aversive stimuli. The executive cognitive deficits observed in section two, and the emotion cue processing deficits observed in section three might therefore result form failures in common mechanisms.

description: A large set of models beyond the Standard Model of particle physics suggest that the top quark plays a special role in fundamental interactions. At the same time some of these models predict that a particle responsible for dark matter is present in the physical spectrum of the theory, and in particular cases dark matter may be specially linked to the top sector. Such a new physics configuration occurs, for instance, in composite frameworks that additionally feature vector-like quarks as mediators of the interactions of the dark matter with the Standard Model. We investigate the interplay of top-philic dark matter and the presence of several vector-like top partners. Such a non-minimal setup with several vector-like fermions is typical of composite scenarios, and we make use of an effective model to study to which extent such non-minimality modifies the collider and cosmological phenomenology of the minimal model, the latter only including one vector-like mediator of the dark matter interactions with the Standard Model.

description: Let $\mathcal{W}^{n}$ be the class of $C^{\infty }$ complete simply connected $n-$dimensional manifolds without conjugate points. The hyperbolic space as well as Euclidean space are good examples of such manifolds. Let $% W\in \mathcal{W}^{n}$ and let $A$ be a subset of $W$. This article aims at characterization and building convex and starshaped sets in this class from inside. For example, it is proven that, for a compact starshaped set, the convex kernel is the intersection of stars of extreme points only. Also, if a closed unbounded convex set $A$ does not contain a totally geodesic hypersurface and its boundary has no geodesic ray, then $A$ is the convex hull of its extreme points. This result is a refinement of the well-known Karein-Millman theorem.

The development of academic skills: An investigation into the mechanisms of integration within and external to the curriculum of first-year undergraduates
Creators: name: Redding, Peter
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Higher education

description: This thesis investigates a change management project involving the attempts of a university faculty to develop the academic skills of first-year undergraduates. While much of this effort had taken place within stand-alone modules dedicated to research skills or personal development, it was recognised that there were multiple influences shaping the student experience. Therefore, the project sought to achieve a more integrated approach, as guided by current pedagogical theory and understandings of organisational behaviour. The project was conducted within an over-arching framework of action research, in which each year of delivery represented iterative cycles with modifications. In order to further investigate the practices and their context, a series of semi-structured, qualitative interviews were conducted with key personnel who had all contributed, in some way, to skills development throughout the organisational structure of the university. The interviews used a form of projective technique which focussed the participants on their roles within the organisation, their relationships with the curriculum and university departments, as well as their place within the student experience. The resultant data was analysed through a grounded theory approach. The analysis provided factual data, unique perspectives and, perhaps more importantly, a more holistic overview. From this, it was possible to propose a new analytical tool for guiding future efforts, one which encompassed the theoretical underpinnings of teaching and learning within HE, with the pragmatic considerations of implementation, thus combining pedagogical theory and management theory. Paradoxically, the paradigm embraced the instrumental or utilitarian tendencies exhibited by some students in order to achieve the longer-term goal of producing independent learners. This emergent paradigm guided further interventions which acted at a local level to foster better communication among key players and to integrate the contents with the wider curriculum and student experience.
Function spaces of logarithmic smoothness: embeddings and characterizations

Publisher: name: Zenodo
Year: 2023

description: In this paper we present a comprehensive treatment of function spaces with logarithmic smoothness (Besov, Sobolev, Triebel-Lizorkin). We establish the following results:

Sharp embeddings between the Besov spaces defined by differences and by Fourier-analytical decompositions as well as between Besov and Sobolev/Trie\-bel-Lizorkin spaces;

Various new characterizations for Besov norms in terms of different K-functionals. For instance, we derive characterizations via ball averages, approximation methods, heat kernels, and Bianchini-type norms;

Sharp estimates for Besov norms of derivatives and potential operators (Riesz and Bessel potentials) in terms of norms of functions themselves. We also obtain quantitative estimates of regularity properties of the fractional Laplacian.

The key tools behind our results are limiting interpolation techniques and new characterizations of Besov and Sobolev norms in terms of the behavior of the Fourier transforms for functions such that their Fourier transforms are of monotone type or lacunary series.

Digital Imaging: its current and future influence upon the creative practice of textile and surface pattern designers
Creators: name: Treadaway, Cathy
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Other information and computing sciences not elsewhere classified

description: This thesis describes research into the impact of digital imaging technology on the creative practice of artists and designers in the field of printed surface pattern for textiles. It examines how digital tools support creative thinking and enhance innovation through the visualisation, manipulation and communication of imagery, and assesses the role and importance of memory and physical experience in creative digital practice. Recent developments in digital ink jet printing technology now enable practitioners to translate digital imagery directly onto textiles. The research provides evidence to assist future technological development, and effective design strategies are identified for implementation within creative textile practice. A contextual review, informed by visits to practitioners, industry and education, and a critical review of published literature, identifies key issues examined in the research. These include the ways in which digital technology supports creative thinking and how communication of visual data facilitates collaborative practice. The rationale for the use of qualitative research methods in the project is explained. A case study, documented using video and audio recordings of interviews, and photography and research journals to gather data on site, is described. Practical investigations, emanating from the field study visits, and an independent experimental body of work created by the researcher, provide additional data to elucidate how digital tools support creative practice. The findings are informed by feedback and evaluation from telephone conversations and personal correspondence from the participants, along with analysis of the research data. Digital tools are shown to support creative thinking, providing a means of stimulating, manipulating, and outputting printed digital imagery. The collaborative investigations demonstrate how communication of visual imagery, via the Internet and portable digital memory storage media, is able to enhance creative practice. Recommendations are also made for future research in areas including colour communication, 3D printing and flexible textile displays.

description: We study correlated transport in a Josephson junction array for small Josephson energies. In this regime transport is dominated by Cooper-pair hopping, although we observe that quasiparticles can not be neglected. We assume that the energy dissipated by a Cooper-pair is absorbed by the intrinsic impedance of the array. This allows us to formulate explicit Cooper-pair hopping rates without adding any parameters to the system. We show that the current is correlated and crucially, these correlations rely fundamentally on the interplay between the Cooper-pairs and equilibrium quasiparticles.

description: Here we look at an application of the Hartle metric to describe a rotating version of the spherical string cloud/ global monopole solution. While rotating versions of this solution have previously been constructed via the Newman-Janis algorithm, that process does not preserve the equation of state. The Hartle method allows for preservation of equation of state, at least in the sense of a slowly rotating perturbative solution. In addition to the direct utility of generating equations which could be used to model a region of a rotating string cloud or similar system, this work shows that it is possible to adapt the Hartle metric to slowly rotating anisotropic systems with Segre type [(11)(1,1)] following an equation of state between the distinct eigenvalues.

description: Empirical evidence suggesting that living systems might operate in the vicinity of critical points, at the borderline between order and disorder, has proliferated in recent years, with examples ranging from spontaneous brain activity to flock dynamics. However, a well-founded theory for understanding how and why interacting living systems could dynamically tune themselves to be poised in the vicinity of a critical point is lacking. Here we employ tools from statistical mechanics and information theory to show that complex adaptive or evolutionary systems can be much more efficient in coping with diverse heterogeneous environmental conditions when operating at criticality. Analytical as well as computational evolutionary and adaptive models vividly illustrate that a community of such systems dynamically self-tunes close to a critical state as the complexity of the environment increases while they remain non-critical for simple and predictable environments. A more robust convergence to criticality emerges in co-evolutionary and co-adaptive set-ups in which individuals aim to represent other agents in the community with fidelity, thereby creating a collective critical ensemble and providing the best possible trade-off between accuracy and flexibility. Our approach provides a parsimonious and general mechanism for the emergence of critical-like behavior in living systems needing to cope with complex environments or trying to efficiently coordinate themselves as an ensemble.

The white Caribbean home: a study of Venezuelan, Cuban, and Puerto Rican migrants in the suburbs of Houston, TX
Creators: name: Mercado Diaz, Mario
Publisher: name: No Publisher Supplied

description: Since the beginning of the new millennium, social scientists have found that, much like the general population, Latin American and Caribbean migrants have been settling in greater numbers in Southern and Mid-Western cities and towns. This “new settlement” literature has focused on how race and racism, along with ethnic identities and tensions, have generated new opportunities and challenges for migrants in new settlement areas or emerging gateways. However, a handful of studies have accounted for how racial inequality outside and within the Latin American and Caribbean favors white or light-skinned Latinx. Likewise, few studies have looked at how differences in nationality and ethnicity shape migrant experiences in new destinations with a long-standing history of Hispanic migration. To address the shortcomings of these fields of study, I address three main empirical questions: 1) What is the residential distribution of Venezuelan, Cuban, and Puerto Rican migrants, and what can that this tells us about their residential mobility and neighborhood preferences?, 2) What are the effects, if any, these new migrant groups have on neighborhood characteristics?, and 3) How do these migrants understand and describe the factors that affect their reception and experiences in a new migrant destination versus an established migrant destination? I answer these research questions using statistical, visual, and ethnographic analysis of the neighborhoods, communities and homes of foreign-born Puerto Rican, Venezuelan and Cuban migrants in the suburbs of Houston, TX. Houston is not a traditional migrant destination for any of these three groups: U.S.-bound Puerto Rican migration has traditionally been associated with the Northeast and Chicago, while Cuban and Venezuelan migration has generally gravitated towards South Florida. I found that Puerto Rican and Venezuelan migrants were fairing better than Mexicans and Cubans. In turn, the influx of Cubans had started to change the neighborhood composition in downtown Houston. These changes could be explained by racial and class inequality within the migrant waves, and the position migrants maintained in the social hierarchies of Houston.

description: We study the conformal bootstrap in fractional space-time dimensions, obtaining rigorous bounds on operator dimensions. Our results show strong evidence that there is a family of unitary CFTs connecting the 2D Ising model, the 3D Ising model, and the free scalar theory in 4D. We give numerical predictions for the leading operator dimensions and central charge in this family at different values of D and compare these to calculations of phi^4 theory in the epsilon-expansion.

description: Periodic Golay pairs are a generalization of ordinary Golay pairs. They can be used to construct Hadamard matrices. A positive integer $v$ is a (periodic) Golay number if there exists a (periodic) Golay pair of length $v$. Taking into the account the results obtained in this note and an yet unpublished new result, there are only seven known periodic Golay numbers which are definitely not Golay numbers, namely 34,50,58,68,72,74,82. We construct here periodic Golay pairs of lengths 74,122,164,202,226. It is apparently unknown whether 122,164,202,226 are Golay numbers. The smallest length for which the existence of periodic Golay pairs is undecided is now 90.

description: Despite recent advances and focus on rigorous uncertainty quantification for microscopic models of quantum many-body systems, the uncertainty on the dynamics of those systems has been under-explored. To address this, we have used time-dependent Hartree-Fock to examine the model uncertainty for a collection of low-energy, heavy-ion fusion reactions. Fusion reactions at near-barrier energies represent a rich test-bed for the dynamics of quantum many-body systems owing to the complex interplay of collective excitation, transfer, and static effects that determine the fusion probability of a given system. While the model uncertainty is sizable for many of the systems studied, the primary contribution comes from ill-constrained static properties, such as the neutron radius of neutron-rich nuclei. These large uncertainties motivate the use of information from reactions to better constrain existing models and to infer static properties from reaction data.

description: Accurately and timely detecting multiscale small objects that contain tens of pixels from remote sensing images (RSI) remains challenging. Most of the existing solutions primarily design complex deep neural networks to learn strong feature representations for objects separated from the background, which often results in a heavy computation burden. In this article, we propose an accurate yet fast object detection method for RSI, named SuperYOLO, which fuses multimodal data and performs high-resolution (HR) object detection on multiscale objects by utilizing the assisted super resolution (SR) learning and considering both the detection accuracy and computation cost. First, we utilize a symmetric compact multimodal fusion (MF) to extract supplementary information from various data for improving small object detection in RSI. Furthermore, we design a simple and flexible SR branch to learn HR feature representations that can discriminate small objects from vast backgrounds with low-resolution (LR) input, thus further improving the detection accuracy. Moreover, to avoid introducing additional computation, the SR branch is discarded in the inference stage, and the computation of the network model is reduced due to the LR input. Experimental results show that, on the widely used VEDAI RS dataset, SuperYOLO achieves an accuracy of 75.09% (in terms of mAP50 ), which is more than 10% higher than the SOTA large models, such as YOLOv5l, YOLOv5x, and RS designed YOLOrs. Meanwhile, the parameter size and GFLOPs of SuperYOLO are about 18 times and 3.8 times less than YOLOv5x. Our proposed model shows a favorable accuracy and speed tradeoff compared to the state-of-the-art models. The code will be open-sourced at https://github.com/icey-zhang/SuperYOLO.

description: We show that the computational model based on local Fermionic modes in place of qubits does not satisfy local tomography and monogamy of entanglement, and has mixed states with maximal entanglement of formation. These features directly follow from the parity conservation corresponding to the parity superselection rule. We generalize quantum superselection rules to general probabilistic theories as sets of linear constraints on the convex set of states. We then provide a link between the cardinality of the superselection rule and the degree of holism of the resulting theory.
