description: For more than a century, cerebral cartography has been driven by investigations of structural and morphological properties of the brain across spatial scales and the temporal/functional phenomena that emerge from these underlying features. The next era of brain mapping will be driven by studies that consider both of these components of brain organization simultaneously -- elucidating their interactions and dependencies. Using this guiding principle, we explored the origin of slowly fluctuating patterns of synchronization within the topological core of brain regions known as the rich club, implicated in the regulation of mood and introspection. We find that a constellation of densely interconnected regions that constitute the rich club (including the anterior insula, amygdala, and precuneus) play a central role in promoting a stable, dynamical core of spontaneous activity in the primate cortex. The slow time scales are well matched to the regulation of internal visceral states, corresponding to the somatic correlates of mood and anxiety. In contrast, the topology of the surrounding "feeder" cortical regions show unstable, rapidly fluctuating dynamics likely crucial for fast perceptual processes. We discuss these findings in relation to psychiatric disorders and the future of connectomics.

Canonical extension of Whittaker distributions for GL(n,R)
Creators: name: Kim, Doyon
Publisher: name: No Publisher Supplied
Year: 2023

description: The “multiplicity one theorem” asserts that the space of Whittaker functionals on irreducible representations of GL(r, R) is at most one-dimensional. This was originally proven by Piatetski-Shapiro [10] and Shalika [11]. In [4], Kostant showed that the dimension of the space of Whittaker functionals for any principal series representation of a quasisplit linear Lie group is exactly one. We give a new proof of the existence of Whittaker functionals on the principal series representations of GL(n, R) by an explicit construction using the integration pairing of Whittaker distributions against smooth functions in the principal series representations. This pairing gives the Jacquet integral. We derive formulas for a change of variables in the integral, that enable us to compute the Jacquet integral directly by means of integration by parts and thereby prove its analytic continuation. This legitimizes the pairing of Whittaker distributions and smooth functions, hence proving the existence of Whittaker functionals.

description: During the joining of two metal sheets by welding, a process-specific geometry of the weld is created. The local geometry of the created weld has a decisive influence on its fatigue strength. This is due to stress concentration at the geometric notches. In this paper, a process known from mechanical engineering called deep rolling is applied on butt welds. The influence on the local weld geometry and the local stress concentration after deep rolling is investigated. Additionally, a novel automated measurement system using optical laser line scanning is presented. The system is qualified for the evaluation of the local weld geometry regarding its flank angles and toe radii. The presented investigations show that the deep rolling process influences the stress concentrations determined by 2D-FE-simulations using real scan data. A correlation between the difference in toe radii or local notch stresses before and after deep rolling and the initial flank angle was found. This indicates that there are process and geometry specific conditions for the successful application of the deep rolling process.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: While exposure and response prevention (ERP) is currently the most effective psychological treatment for unwanted, intrusive thoughts associated with Obsessive Compulsive Disorder (OCD), the procedures involved in ERP are challenging and may contribute to treatment refusal. To address this problem, researchers have begun to evaluate alternative treatments for OCD, such as Acceptance and Commitment Therapy (ACT). The purpose of the present study was to examine the relative effects of a single session of ACT or ERP for obsessional thoughts. Fifty-six undergraduate participants with obsessional thoughts were randomly assigned to receive a brief version of ERP, ACT, or a control condition. We found that the ERP group displayed greater willingness and that the ACT group demonstrated lower dysfunctional cognitions at follow-up. There were no differences between ACT and ERP on any other variables. Thus, no clear patterns emerged that suggest substantial differences between ACT and ERP in efficacy or change processes.

description: A computer-aided process design methodology is used to determine the limits of NH3/H2O mixtures in different heat pump cycles from 20 °C to 150 °C. The evaluation is based on a defined parameter set consisting of the coefficient of performance, total heat transfer area and volumetric heat capacity. Simple cycles with two heat flows were chosen to meet good process integration capabilities. The results are shown in a sink outlet/temperature lift matrix considering current technical limits. R1366mzz(Z) in a standard compression cycle with internal heat exchanger serves as a benchmark. To provide temperatures up to 150 °C the lift of the heat pump has to increase to about 80 K of which only the wet compressions cycle with NH3/H2O is capable of. The working domains of NH3/H2O and R1366mzz(Z) are similar, when a two-stage compression for NH3/H2O is applied.

description: Titanium and titanium alloys have high strength at low density, good corrosion resistance and excellent biocompatibility. Therefore, the use of titanium materials is well established in high-performance applications such as aerospace and biomedical. However, titanium and titanium alloys such as Ti–6Al–4 V have low thermal conductivity, exhibit unfavorable chip formation with typical segmented chips and have high chemical affinity to surrounding elements such as oxygen. Tool wear and the properties of the component surface and sub-surface are significantly influenced by the presence of oxygen and resulting chemical interactions. Among other things, chemical reactions such as oxidation occur due to the high temperatures and presence of oxygen. In this work, the chip formation of Ti–6Al–4 V at different cutting speeds in discontinuous orthogonal cutting process under different atmospheres is investigated. A conventional air atmosphere, a pure argon atmosphere and a silane-doped atmosphere were used. The oxygen content of the silane-doped argon atmosphere corresponds to an extremely high vacuum (XHV), which is practically oxygen-free. It was found that chip formation is affected by the surrounding atmosphere. At the cutting speed vc = 80 m/min, non-periodic segmentation is present under oxygen-free atmosphere, while segmental chip formation occurs under air. This is accompanied by up to 16.5% lower feed force under inert gas atmosphere, which is due to reduced friction caused by the use of an oxygen-free atmosphere.

description: Right handedness is one of the most prominent markers of human functional brain asymmetry. Deviation from this norm appears to be associated with certain developmental disorders. While many studies have dealt with the genetic contribution to the determination of handedness, few have examined whether environmental factors that are subtler than forced hand switching can modulate the development of handedness. In this study, we exposed rats to a novel environment for 3 min daily during their first 3 weeks of life and found that their paw preferences during both infancy and adulthood showed a leftward shift compared with the controls. This result suggests that 'handedness' can be modified by rather subtle early environmental manipulation. Since exposure to a novel environment does not involve a direct asymmetric activation of the sensory--motor system underlying paw-use, mechanisms beyond this paw-specific system must exist to mediate the observed modulation of 'handedness'.
Avalanches of Attention: Positive Feedback in Media Coverage of Social Movement Organizations
Creators: name: Seguin, Charles
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: I present a positive feedback model to explain why media attention to SMOs is so unequal, volatile and unpredictable. Receiving some degree of media attention helps groups to receive still more--a cumulative advantage, or rich-get-richer, process. The model presents two empirically verifiable implications: (1) levels of media attention will be power-law distributed across SMOs and (2) coverage dynamics will be path-dependent and thus potentially sensitive to small events early in organization histories. Using new methodology from statistical physics I show that media attention is indeed power-law distributed within three large datasets describing counts of media stories to SMOs spanning multiple movements, time periods and media outlets. I then explore the path dependent nature of media coverage with a comparative analysis of the Black Panther Party and the Revolutionary Action Movement. The two groups were initially very similar, the Black Panthers, however, were able to turn early media attention into further media attention, while the Revolutionary Action Movement was not, eventually resulting in a roughly eighty fold difference in levels of media attention between the two groups. Jointly, the quantitative and qualitative results provide broad support for the positive feedback model.

description: BACKGROUND: This study investigated verb argument structure effects in children with specific language impairment (SLI).
AIMS: A picture-naming paradigm was used to compare the response times and naming accuracy for nouns and verbs with differing argument structure between Spanish-speaking children with and without language impairment.
METHODS & PROCEDURES: Twenty-four children with SLI (ages 5;3-8;2 [years;months]), 24 age-matched controls (ages 5;3-8;2), 24 MLU-w controls (ages 3;3-7;1 years), and 31 adults participated in a picture-naming study.
OUTCOMES & RESULTS: The results show all groups produced more correct responses and were faster for nouns than all verbs together. As regards verb type accuracy, there were no differences between groups in naming one-argument verbs. However, for both two- and three-argument verbs, children with SLI were less accurate than adults and age-matched controls, but similar to the MLU-matched controls. For verb type latency, children with SLI were slower than both the age-matched controls and adults for one- and two-argument verbs, while no differences were found in three-argument verbs. No differences were found between children with SLI and MLU-matched controls for any verb type.
CONCLUSIONS & IMPLICATIONS: It has been shown that the naming of verbs is delayed in Spanish children with SLI. It is suggested that children with SLI may have problems encoding semantic representations.

description: Axial and torsional fatigue tests at different stress ratios were performed on a structural adhesive designed for wind turbine rotor blades. By employing previously optimized specimens, fatigue properties were recorded without influences of manufacturing-induced defects such as pores. The Stüssi S–N model was an excellent fit to the data and was combined with a Haibach extension line to account for uncertainties in the gigacycle fatigue regime. A comparison of the results with hand-mixed specimens revealed significant and load level-dependent differences, indicating that manufacturing safety factors should be applied to the slope of the S–N curve. The experiments were accompanied by stiffness degradation measurements, which enabled an analysis of Young's and shear modulus degradation interactions. The degradation was modeled using power law fits, which incorporated load level-dependent fitting parameters to allow for a full description of the stiffness reduction and a prediction of the residual fatigue life of run-out specimens.

description: Abstract: "Intelligence is closely related with adaptivity -- with problem-solving, learning, and evolution. A science of intelligent systems has to be a science of adaptive systems, with all which that entails for the difficulty of finding genuine invariants. Some of the invariance in intelligence is imposed by the structure of the inner environment -- the limits, for example, of human short term memory. Some of it is imposed by the outer environment, the need to search very large spaces selectively. Some of the invariance is to be found in the structure of learning systems, rather than in the highly adapted performance systems they produce. But, in cognitive science we must be prepared to recognize that the invariants in an adaptive system are likely to be limited to specific times and places; that in the long run, almost any aspect of them can change adaptively."

description: Recent research on fractions has broadened and deepened theories of numerical development. Learning about fractions requires children to recognize that many properties of whole numbers are not true of numbers in general and also to recognize that the one property that unites all real numbers is that they possess magnitudes that can be ordered on number lines. The difficulty of attaining this understanding makes the acquisition of knowledge about fractions an important issue educationally, as well as theoretically. This article examines the neural underpinnings of fraction understanding, developmental and individual differences in that understanding, and interventions that improve the understanding. Accurate representation of fraction magnitudes emerges as crucial both to conceptual understanding of fractions and to fraction arithmetic.

description: A vortex in Bose-Einstein condensates is a localized object which looks much like a tiny tornado storm. It is well described by mean-field theory. In the present work we go beyond the current paradigm and introduce many-body vortices. These are made of {\it spatially-partitioned} clouds, carry definite total angular momentum, and are fragmented rather than condensed objects which can only be described beyond mean-field theory. A phase diagram based on a mean-field model assists in predicting the parameters where many-body vortices occur. Implications are briefly discussed.

description: Galaxy clusters' structure, dominated by dark matter, is traced by member galaxies in the optical and hot intra-cluster medium (ICM) in X-rays. We compare the radial distribution of these components and determine the mass-to-light ratio vs. system mass relation. We use 14 clusters from the REXCESS sample which is representative of clusters detected in X-ray surveys. Photometric observations with the Wide Field Imager on the 2.2m MPG/ESO telescope are used to determine the number density profiles of the galaxy distribution out to $r_{200}$. These are compared to electron density profiles of the ICM obtained using XMM-Newton, and dark matter profiles inferred from scaling relations and an NFW model. While red sequence galaxies trace the total matter profile, the blue galaxy distribution is much shallower. We see a deficit of faint galaxies in the central regions of massive and regular clusters, and strong suppression of bright and faint blue galaxies in the centres of cool-core clusters, attributable to ram pressure stripping of gas from blue galaxies in high density regions of ICM and disruption of faint galaxies due to galaxy interactions. We find a mass-to-light ratio vs. mass relation within $r_{200}$ of $\left(3.0\pm0.4\right) \times 10^2\, h\,\mathrm{M}_{\odot}\,\mathrm{L}_{\odot}^{-1}$ at $10^{15}\,\mathrm{M}_{\odot}$ with slope $0.16 \pm 0.14$, consistent with most previous results.

description: Hemispatial neglect is a neurological disorder characterized by a failure to represent information appearing in the hemispace contralateral to a brain lesion. In addition to the perceptual consequences of hemispatial neglect, several authors have reported that hemispatial neglect impairs visually guided movements. Others have reported that the extent of the impairment depends on the type of visually guided task. Finally, in some cases, neglect has been shown to impair visual perception without affecting visuomotor control in relation to the very same stimuli. While neglect patients may be able to successfully pick up an object they have difficulty perceiving in its entirety, it does not mean that they are picking up the object in the same way that a neurologically intact individual would. In the current study, patients with hemispatial neglect were presented with irregularly shaped objects, directly in front of them, that lacked clear symmetry and required an analysis of their entire contour in order to calculate stable grasp points. In a perceptual discrimination task, the neglect patients had difficulty distinguishing one object from another on the basis of their shape. In a grasping task, the neglect patients showed more variance in the position of their grasp on the target objects than their control subjects, with an overall shift to the relative right side of the presented objects. The perceptual and visuomotor deficits seen in patients with hemispatial neglect deficits may be the result of an inability to form good structural representations of the entire object for use in visual perception and visuomotor control.

description: As a cost-effective hole production technique, friction drilling is widely used in industrial and automotive manufacturing. Compared with the traditional bolted connection, it enables the fastening of thin metal sheets and thin-walled tubular profiles. Friction drilling results in higher thread length and joint strength, thus better fulfilling the demand for lightweight structures. However, in the numerical simulation of friction drilling, the traditional finite element method encounters difficulties caused by the extreme deformation and complex failure of the material. A large number of elements are usually deleted due to the failure criterion, which significantly reduces the solution accuracy. The development of meshless methods over the past 20 years has alleviated this problem. Especially the Smoothed Particle Galerkin (SPG) method proposed in recent years and incorporating a bond-based failure mechanism has been shown to be advantageous in material separation simulations. It does not require element removal and can continuously evolve each particle's information such as strain and stress after the material failure. Therefore, the SPG method was used in this research for the simulation of frictional drilling of HX220 sheet metal. First the particle distance and the friction coefficient were varied to investigate the applicability of the SPG method to the friction drilling process. Predicted and experimental results were compared and found to be in high agreement. Furthermore, the influence of input parameters, such as sheet thickness, feed rate and rotational speed, on axial force as well as torque of the tool and the surface temperature of the workpiece during friction drilling was investigated numerically.

Excavating abandoned artificial life: a case study in digital media archeology

description: What happens when an artist abandons their artificial life-like creation for six years? The field of computational artificial life is rooted within a rapidly expanding technological realm, resulting in challenging possibilities and an equally compelling set of critical questions. This presentation focuses on one of these questions; how to deal with excavating remnants of a computational entity that has been abandoned. We will present both conceptual and technological aspects concerning this subject by exploring the H4aC (Habitat for a Commensal) project that came to be in 2012. The installation is a semi-public sculpture positioned in a rural area next to a biomass power plant in the town of Oostrozebeke, Belgium. It was conceived as a space architecture-inspired structure which accommodates an artificial life form. The generative entity existed in an ongoing evolutionary state. This state was triggered by an algorithmic environment and fed by a multitude of datastreams pulled from the energy plant. As such the morphology of the virtual organism served as a repository for the power plants' history of activity. The machine which generated the computational artificial life was retrieved in 2018. Up until then it served as a breeding ground for countless evolutionary cycles during which the organism thrived for years. The life-like creatures' behavioral and structural blueprints - its digital genetic code - was stored on the machine's hard drive with each mutation. This presentation will demonstrate critical insights that result from the reconstruction of computational artificial life residing within the H4aC sculpture. Revisualising the phylogenetic path of the bio-inspired organism came with technical challenges, for example the differences between the current technological context and the one when the installation originated. Tackling these technological problems required a journey through digital media archaeology, but also gave rise to insights on notional aspects of abandoning artificial life. Towards what extent do artists and scientist need to develop a responsibility for the artificial life that they use as a medium for their work? For these reasons and more the presentation will outline a tentative framework, extrapolating findings which are potentially representative for the broader field of artificial life and computational poetics.

description: Our main result is that for all sufficiently large $x_0>0$, the set of commensurability classes of arithmetic hyperbolic 2- or 3-orbifolds with fixed invariant trace field $k$ and systole bounded below by $x_0$ has density one within the set of all commensurability classes of arithmetic hyperbolic 2- or 3-orbifolds with invariant trace field $k$. The proof relies upon bounds for the absolute logarithmic Weil height of algebraic integers due to Silverman, Brindza and Hajdu, as well as precise estimates for the number of rational quaternion algebras not admitting embeddings of any quadratic field having small discriminant. When the trace field is $\mathbf{Q}$, using work of Granville and Soundararajan, we establish a stronger result that allows our constant lower bound $x_0$ to grow with the area. As an application, we establish a systolic bound for arithmetic hyperbolic surfaces that is related to prior work of Buser-Sarnak and Katz-Schaps-Vishne. Finally, we establish an analogous density result for commensurability classes of arithmetic hyperbolic 3-orbifolds with small area totally geodesic $2$-orbifolds.

description: We consider an infinite periodic array of dielectric rods in vacuum with the aim to demonstrate three types of a Bloch bound states in the continuum (BSC), symmetry protected with a zero Bloch vector, embedded into one diffraction channel with nonzero Bloch vector, and embedded into two and three diffraction channels. The first and second types of the BSC exist in a wide range of material parameters of the rods, while the third occurs only at a specific value of the radius of the rods. We show that the second type supports the power flux along the array. In order to find BSC we put forward an approach based on the expansion over the Hankel functions. We show how the BSC reveals itself in the scattering function when the singular BSC point is approached along a specific path in the parametric space.

The role of public relations in socially responsible business
Creators: name: Carpenter, Floride Hawkins
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Public relations professionals need to understand their role in order to contribute, participate and potentially help shape the future of business through corporate social responsibility. This study examines how public relations is practiced in a socially responsible organization through a case study of a senior public relations manager working in a socially responsible company. The basic premise of this study is that public relations in a socially responsible organization will exhibit characteristics of "excellence" as defined by Grunig, Grunig, and Dozier (2002). Specifically this includes the organizational role enacted by the public relations professional and the model of practice employed by the public relations professional.

description: The equivalence postulate approach to quantum mechanics aims to formulate quantum mechanics from a fundamental geometrical principle. Underlying the formulation there exists a basic cocycle condition which is invariant under $D$--dimensional Möbius transformations with respect to the Euclidean or Minkowski metrics. The invariance under global Möbius transformations implies that spatial space is compact. Furthermore, it implies energy quantisation and undefinability of quantum trajectories without assuming any prior interpretation of the wave function. The approach may be viewed as conventional quantum mechanics with the caveat that spatial space is compact, as dictated by the Möbius symmetry, with the classical limit corresponding to the decompactification limit. Correspondingly, there exists a finite length scale in the formalism and consequently an intrinsic regularisation scheme. Evidence for the compactness of space may exist in the cosmic microwave background radiation.

description: There exist two formulations for quantum heat engine that models an energy transfer between two microscopic systems. One is semi-classical scenario, and the other is full quantum scenario. The former is formulated as a unitary evolution for the internal system, and is adopted by the community of statistical mechanics. In the latter, the whole process is formulated as unitary, and is adopted by the community of quantum information. This paper proposes a model for quantum heat engine that transfers energy from a collection of microscopic systems to a macroscopic system like a fuel cell. In such a situation, the amount of extracted work is visible for a human. For this purpose, we formulate quantum heat engine as the measurement process whose measurement outcome is the amount of extracted work. Under this model, we derive a suitable energy conservation law and propose a more concrete submodel. Then, we derive a novel trade-off relation between the measurability of the amount of work extraction and the coherence of the internal system, which examines the application of the semi-classical scenario to a heat engine transferring an energy from a collection of microscopic systems to a macroscopic system.

description: Most voluntary actions rely on neural circuits that map sensory cues onto appropriate motor responses. One might expect that for everyday movements, like reaching, this mapping would remain stable over time, at least in the absence of error feedback. Here we describe a simple and novel psychophysical phenomenon in which recent experience shapes the statistical properties of reaching, independent of any movement errors. Specifically, when recent movements are made to targets near a particular location subsequent movements to that location become less variable, but at the cost of increased bias for reaches to other targets. This process exhibits the variance-bias tradeoff that is a hallmark of Bayesian estimation. We provide evidence that this process reflects a fast, trial-by-trial learning of the prior distribution of targets. We also show that these results may reflect an emergent property of associative learning in neural circuits. We demonstrate that adding Hebbian (associative) learning to a model network for reach planning leads to a continuous modification of network connections that biases network dynamics toward activity patterns associated with recent inputs. This learning process quantitatively captures the key results of our experimental data in human subjects, including the effect that recent experience has on the variance-bias tradeoff. This network also provides a good approximation of a normative Bayesian estimator. These observations illustrate how associative learning can incorporate recent experience into ongoing computations in a statistically principled way.
The Ptolemies and the 3rd Century B.C.E. Ceramic Assemblage

description: The Ptolemaic political, military, and economic interests in the 3rd century B.C.E. Aegean and Greek mainland fostered cultural exchange. I examine the ceramic evidence from two sites to assess the network of interaction and its impact on the function and production of Hellenistic pottery types. The ceramic assemblage from Eretria, a city with a historically Greek affiliation, will serve as a point of comparison for the evidence from Koroni, a Ptolemaic site in Attika. The ceramic assemblage from Koroni tells us three things: 1) the fine ware indicates that the Ptolemies had already begun to be involved in what will become the Hellenistic koine, 2) Koroni was not directly linked with Athens, which throws into question the function of the site, and 3) the Ptolemaic intervention in and then withdrawal from Attika and the Aegean was one reason behind the fluctuation in the market for Attic black gloss pottery.
Physics of the cosmic microwave background anisotropy

description: Observations of the cosmic microwave background (CMB), especially of its frequency spectrum and its anisotropies, both in temperature and in polarization, have played a key role in the development of modern cosmology and our understanding of the very early universe. We review the underlying physics of the CMB and how the primordial temperature and polarization anisotropies were imprinted. Possibilities for distinguishing competing cosmological models are emphasized. The current status of CMB experiments and experimental techniques with an emphasis toward future observations, particularly in polarization, is reviewed. The physics of foreground emissions, especially of polarized dust, is discussed in detail, since this area is likely to become crucial for measurements of the B modes of the CMB polarization at ever greater sensitivity.

description: The use of Digital Object Identifiers (DOI) for scientific data and scientific software is increasingly common practice in many disciplines, including in Geodesy. Today, DOI-referenced datasets are fully citable in scholarly literature and more and more journals require the public availability of data underlying scientific results and their citation in research articles. Technical implementations, like Scholix (a framework for Scholarly Link Exchange) enable direct links between literature and data and support the visibility of research data. Key elements for enabling these links and for interconnecting publications with data, code, persons, institutions, etc., and are resolvable persistent identifier (PID), that should be included in the DOI metadata. Geodetic services of the International Association for Geodesy (IAG) are international key player for geodetic data provision and distribution. Their operating institutions and funding agencies increasingly require the provision of tangible data use and access statistics. Credit through citation was a major reason for the IAG’s Global Geodetic Observing System (GGOS) to establish a Working Group on using DOI for geodetic data sets (GGOS DOI WG) and for the working group members. The GGOS DOI WG was established in 2019 and includes international representatives of IAG Services and geodetic data centres as well as associated members that aims at developing best practices and recommendations for the consistent implementation of DOIs across all IAG Services and in the greater geodetic community. This presentation will give an update on recent group activities and on the status of DOI minting for geodetic datasets across IAG Services.
