Classical Zero-Point Radiation and Relativity: The Problem of Atomic Collapse Revisited
Creators: name: Boyer, Timothy H.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: The physicists of the early 20th century were unaware of two aspects which are vital to understanding some aspects of modern physics within classical theory. The two aspects are: 1) the presence of classical electromagnetic zero-point radiation, and 2) the importance of special relativity. In classes in modern physics today, the problem of atomic collapse is still mentioned in the historical context of the early 20th century. However, the classical problem of atomic collapse is currently being treated in the presence of classical zero-point radiation where the problem has been transformed. The presence of classical zero-point radiation indeed keeps the electron from falling into the Coulomb potential center. However, the old collapse problem has been replaced by a new problem where the zero-point radiation may give too much energy to the electron so as to cause self-ionization. Special relativity may play a role in understanding this modern variation on the atomic collapse problem, just as relativity has proved crucial for a classical understanding of blackbody radiation.

description: Recently it was demonstrated how climate data can be utilized to estimate regional wind power densities. In particular it was shown that the quality of the global scale estimate compared well with regional high resolution studies and a link between surface temperature and moist density in the estimate was presented. In the present paper the methodology is tested further, to ensure that the results using one climate data set are reliable. This is achieved by extending the study to include four ensemble members. With the confidence that one instantiation is sufficient a climate change data set, which was also a result of the UPSCALE experiment, is analyzed. This, for the first time, provides a projection of future changes in wind power resources using this data set. This climate change data set is based on the Representative Concentration Pathways (RCP) 8.5 climate change scenario. This provides guidance for developers and policy makers to mitigate and adapt.

description: Nach dem rassistischen Anschlag in Hanau am 19.02.2020 und dem Mord an George Floyd am 25.05.2020 wurde oftmals von einem Wandel im gesellschaftlichen und medialen Diskurs um Rassismus gesprochen. Ob sich dieser Wandel auch im parlamentarischen Diskurs des deutschen Bundestags widerspiegelt, untersucht dieses Working Paper. Es widmet sich der bislang kaum beforschten Frage, wie Rassismus in parlamentarischen Debatten thematisiert wird und inwiefern Veränderungen im Sprechen über Rassismus im Bundestag zu beobachten sind. In einer vergleichenden Diskursanalyse von Plenarprotokollen der Jahre 2011/12 (Debatten nach der NSU-Selbstenttarnung) und 2020 werden Kontinuitäten, aber auch Diskontinuitäten im Diskurs über Rassismus herausgearbeitet. Während sich einerseits Veränderungen dahingehend zeigen, dass Rassismus im Jahr 2020 deutlich häufiger explizit angesprochen wird und zunehmend rassismuskritische Positionen im Bundestag vertreten werden, konnten vor dem Hintergrund rassismuskritischer Theorie aber auch zahlreiche Strategien der Dethematisierung von Rassismus identifiziert werden, die sowohl 2011/12 als auch 2020 den Diskurs prägen.

description: In this paper we investigate measures of chaos and entanglement in rational conformal field theories in 1+1 dimensions. First, we derive a universal formula for the late time value of the out-of-time-ordered correlators for this class of theories. Our universal result can be expressed as a particular combination of the modular S-matrix elements known as the anyon monodromy scalar. Next, in the explicit setup of a $SU(N)_k$ Wess-Zumino-Witten model, we compare the late time behavior of the out-of-time-ordered correlators and the purity. Interestingly, in the large-c limit, the purity grows logarithmically as in holographic theories; in contrast, the out-of-time-ordered correlators remain, in general, non-vanishing.

description: We give a detailed characterization of optimal trades under budget constraints in a prediction market with a cost-function-based automated market maker. We study how the budget constraints of individual traders affect their ability to impact the market price. As a concrete application of our characterization, we give sufficient conditions for a property we call budget additivity: two traders with budgets B and B' and the same beliefs would have a combined impact equal to a single trader with budget B+B'. That way, even if a single trader cannot move the market much, a crowd of like-minded traders can have the same desired effect. When the set of payoff vectors associated with outcomes, with coordinates corresponding to securities, is affinely independent, we obtain that a generalization of the heavily-used logarithmic market scoring rule is budget additive, but the quadratic market scoring rule is not. Our results may be used both descriptively, to understand if a particular market maker is affected by budget constraints or not, and prescriptively, as a recipe to construct markets.

description: In the wake of recent advances in experimental methods in neuroscience, the ability to record in-vivo neuronal activity from awake animals has become feasible. The availability of such rich and detailed physiological measurements calls for the development of advanced data analysis tools, as commonly used techniques do not suffice to capture the spatio-temporal network complexity. In this paper, we propose a new hierarchical coupled geometry analysis, which exploits the hidden connectivity structures between neurons and the dynamic patterns at multiple time-scales. Our approach gives rise to the joint organization of neurons and dynamic patterns in data-driven hierarchical data structures. These structures provide local to global data representations, from local partitioning of the data in flexible trees through a new multiscale metric to a global manifold embedding. The application of our techniques to in-vivo neuronal recordings demonstrate the capability of extracting neuronal activity patterns and identifying temporal trends, associated with particular behavioral events and manipulations introduced in the experiments.

description: We discuss efficient Bayesian estimation of dynamic covariance matrices in multivariate time series through a factor stochastic volatility model. In particular, we propose two interweaving strategies (Yu and Meng, Journal of Computational and Graphical Statistics, 20(3), 531-570, 2011) to substantially accelerate convergence and mixing of standard MCMC approaches. Similar to marginal data augmentation techniques, the proposed acceleration procedures exploit non-identifiability issues which frequently arise in factor models. Our new interweaving strategies are easy to implement and come at almost no extra computational cost; nevertheless, they can boost estimation efficiency by several orders of magnitude as is shown in extensive simulation studies. To conclude, the application of our algorithm to a 26-dimensional exchange rate data set illustrates the superior performance of the new approach for real-world data.
Variation in congressional public approval: the effect of actual conflict versus perceived conflict on public approval of Congress 1970-2000
Creators: name: Shaffer, Laura Ann
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: This thesis examines the factors that contribute the public’s opinion of Congress. I posit that conflict, whether it is actual conflict or merely the perception of conflict, has the significant negative affect on approval of Congress. Other factors taken into consideration include divided government, presidential approval, and economic expectations. For measures of conflict, I used both a measure of perceived conflict (negative media coverage) and a measure of actual internal conflict (congressional party unity scores.) My results show that perceived conflict can negatively affect opinion. The evidence presented above supports my hypothesis that conflict in Congress makes people uncomfortable and angry with their government producing negative opinions of this branch of government. Media coverage may exacerbate this phenomenon. By overemphasizing conflict that does exist, the media may play a role in the reason Congressional approval is so low in general.

We also find the exact clique number of $Γ(\mathbb{V})$ for some particular cases. Moreover, we provide some results on size, edge-connectivity and chromatic number of $Γ(\mathbb{V})$.

Year: 2016

description: Scan time acceleration, with many clinical and research applications, has been an active research area in magnetic resonance imaging with the introduction of new pulse sequences, parallel imaging (PI) techniques, and methods to acquire multiple slices simultaneously. The development of novel uses for the latest techniques is facilitated by the ability to create customized in-house pulse sequences. In this work, a simultaneous multi-slice radiofrequency (RF) pulse was developed within a sequence programming environment. This RF pulse was then utilized in a reconstruction simulation of a controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA) acquisition with an ill-conditioned coil geometry. The slice-excitation behavior of the in-house developed RF pulse was affirmed along with a successful confirmation of the image reconstruction benefits of the CAIPIRINHA technique. This provided a demonstration of sequence development and the ability to implement CAIPIRINHA in future PI studies requiring a demanding coil-array geometry.

description: Motivated by the famous Waddington's epigenetic landscape metaphor in developmental biology, biophysicists and applied mathematicians made different proposals to realize this metaphor in a rationalized way. We adopt comprehensive perspectives to systematically investigate three different but closely related realizations in recent literature: namely the potential landscape theory from the steady state distribution of stochastic differential equations (SDEs), the quasi-potential from the large deviation theory, and the construction through SDE decomposition and A-type integral.The connections among these theories are established in this paper. We demonstrate that the quasi-potential is the zero noise limit of the potential landscape. We also show that the potential function in the third proposal coincides with the quasi-potential. The most probable transition path by minimizing the Onsager-Machlup or Freidlin-Wentzell action functional is discussed as well. Furthermore, we compare the difference between local and global quasi-potential through the exchange of limit order for time and noise amplitude. As a consequence of such explorations, we arrive at the existence result for the SDE decomposition while deny its uniqueness in general cases. It is also clarified that the A-type integral is more appropriate to be applied to the decomposed SDEs rather than the original one. Our results contribute to a better understanding of existing landscape theories for biological systems.

Year: 2009

description: This thesis compares the Telephos Frieze from the Great Altar at Pergamon to Classical and Hellenistic votive reliefs. Previous authors have alluded to connections between votive reliefs and the Telephos Frieze, but this paper demonstrates the similarities and important differences between the frieze and specific votive reliefs. It argues that the Telephos Frieze evokes compositions and pictorial techniques that also occur in processional, banquet, Pan and Nymph, and hero reliefs. The final chapter addresses the function of the Altar and the Telephos Frieze, which were essential elements of Eumenes II's urban consolidation in the second century B.C.E. This paper concludes that the votive elements of the Telephos Frieze efficaciously associated Attalid dynastic ideology with the personal emotions and beliefs of worshipers, reinforcing dynastic authority within the Pergamene kingdom.

description: We introduce and explore a family of vertex-coloring problems which, surprisingly enough, have not been considered before despite stemming from the problem of Wi-Fi channel assignment. Given a spectrum of colors, endowed with a matrix of interferences between each pair of colors, the Threshold Spectrum Coloring problem fixes the number of colors available and aims to minimize the interference threshold, i.e., the maximum of the interferences at the vertices. Conversely, the Chromatic Spectrum Coloring problem fixes a threshold and aims to minimize the number of colors for which respecting that threshold is possible. As main theoretical results, we prove tight upper bounds for the solutions to each problem. Since both problems turn out to be NP-hard, we complete the scene with experimental results. We propose a DSATUR-based heuristic and study its performance to minimize the maximum vertex interference in Wi-Fi channel assignment, both for randomly generated graphs and for a real-world scenario. Further, for all these graphs we experimentally check the goodness of the theoretical bounds.

Year: 2016

description: There is little research on the services adults with Autism Spectrum Disorders (ASD) use, satisfaction with these services, and barriers to receiving services. Population density may affect service use outcomes. This study aimed to examine service use outcomes and the effect of population density using a Geographical Information Systems (GIS) approach, in adults with ASD diagnosed by the TEACCH Autism program as children. Caregiver surveys from 91 participants were collected and questions about the types of services, barriers to services, and satisfaction with services were analyzed for relations with population density. Results showed that individuals with higher childhood IQ scores were less likely to utilize services, and that living in rural communities decreased service use for all adults studied. Rehabilitation counselors can serve as a resource for increasing knowledge about available services in the communities they serve and advocate for services and community support in more rural areas.

In two space-time dimensions we obtain a sum of three elliptic dilogarithms. The arguments of the elliptic dilogarithms have a nice geometric interpretation. In four space-time dimensions the sunrise integral can be expressed with the $ε^0$- and $ε^1$-solution around two dimensions, mass derivatives thereof and simpler terms.

description: Due to various shortcomings of the visual system, some visual stimuli can only be identified with 100% accuracy if they are shown for a certain amount of time. This time can be measured using the Inspection Time (IT) paradigm. In an IT task, a “pi” figure with differing leg lengths is typically presented briefly (e.g., 20-200 ms) and is then immediately masked to prevent retinal afterimages. Participants are subsequently required to choose which of the two legs was longer. The objective of this task is to determine the shortest amount of time the pi figure needs to be shown for it to be perceived with 80% accuracy. Given that visual processing has been shown to be altered during and /or prior to a movement, the present experiment sought to test how the requirement to perform a motor task affected IT. Twenty-eight participants took part in the experiment, which was comprised of three conditions: no-movement (NM), peak velocity (PV), and foreperiod (FP). In the NM condition, participants grasped a manipulandum and engaged in the IT paradigm. At the end of every trial, participants verbally stated which leg they believed was longest. In the PV condition participants made a rapid movement to a target, and the IT stimulus was presented when their limb reached peak velocity. Finally in the FP condition the IT stimulus was presented during foreperiod (FP). In all three conditions the IT stimulus was randomly presented from between 15-105 ms (in 15 ms increments) and masked for 400 ms. Results showed no significant differences on the IT task between the NM and FP conditions, suggesting no visual upregulation during foreperiod. However, IT performance was significantly poorer in the PV condition in comparison to both the NM and FP condition, suggesting a visual downregulation at that particular movement kinematic.
ONE TEACHER’S JOURNEY IN IMPLEMENTING AND LEARNING THROUGH SYMBOLIC LANGUAGES IN A PUBLIC KINDERGARTEN- A CASE STUDY
Creators: name: Tzeng, Shinyu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: In early childhood education, symbolic languages such as art, drama and music are still considered an essential element in the curriculum, although current policy places greater emphasis on reading, writing and mathematics. The aim of this study was to explore how one teacher integrated symbolic languages into a public kindergarten curriculum, including her methods, motivations, and obstacles. This research was conducted using qualitative methods including Participant Observation in the classroom and semi-structured interviews with the teacher, whose approach was heavily influenced by ideas from Reggio Emilia, Italy. Data analysis highlighted the teacher’s decision-making process and her reflections on teaching through symbolic languages, including the challenges that she faced given district mandates and her students’ different learning needs. Findings of the study include how the teacher interpreted art as being significant in early childhood education, even though she rarely used the term “symbolic languages,” as discussed by Reggio Emilia educators. The teacher described her motives in the implementation of Reggio Emilia ideas, particularly the use of projects to achieve mandated curriculum goals. The study highlights challenges the teacher has faced, and then overcome, as reasons for persisting in her belief of using art in children’s learning. Further research is suggested to see how other teachers attempt to employ Reggio Emilia ideas about symbolic languages in a different context.

description: Thin film Nanocomposite (TFN) membranes are a relatively new class of high-performance semipermeable membranes for Reverse Osmosis (RO) applications. Large scale applications of TFN membranes have not been achieved yet due to the high production cost of the nanoparticles, agglomeration of the nanoparticles in the thin polyamide matrix of the membrane, and leaching out of typically toxic inorganic nanoparticles into the downstream. In this work, these challenges are addressed by incorporation of two different nanofillers: Cellulose NanoCrystals (CNC), and surface functionalized Halloysite NanoTubes (HNT). Amine groups, carboxylic acid groups, and the first generation of poly(amidoamine) (PAMAM) dendrimers were used for functionalization of the HNT. CNC and HNT are environmentally friendly, low/non-toxic, abundant, and inexpensive nanoparticles with a unique size, and chemical properties. TFN membranes were synthesized via in situ interfacial polymerization of m-phenylenediamine (MPD) with trimesoyl chloride (TMC) and the nanoparticles. The control Thin Film Composite (TFC) membranes, and CNC and HNT based TFN membranes were characterized by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), X-Ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared spectroscopy (FTIR) and contact angle measurements. The antifouling capacity of CNC based membranes was investigated with a solution of Bovine Serum Albumin (BSA) as the fouling agent. Also, the leachability of the HNT from the membranes was examined by shaking the membranes in a batch incubator for 48 h, and then tracing the leached out HNT using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Separation characteristics of the membranes were studied by desalination of synthetic brackish water with a cross flow RO filtration system. It was revealed that incorporation of functionalized HNT enhanced the permeate flux without sacrificing the salt rejection (99.1 % ± 0.1 %). Also, incorporation of 0.1% (w/v) CNC doubled the permeate flux (from 30 to 63 L/m2.h at 20 bar) without compromising the salt rejection (97.8%). At the same time, leaching out of HNT from the TFN membranes was decreased as a result of the HNT functionalization and formation of covalent bonds with the TMC. Also, antifouling properties of the CNC-TFN membranes were 11% improved in comparison with control TFC membrane.

description: The paper presents many facets of medical imaging investigations radiological risks. The total volume of prescribed medical investigations proves a serious lack in monitoring and tracking of the cumulative radiation doses in many health services. Modern radiological investigations equipment is continuously reducing the total dose of radiation due to improved technologies, so a decrease in per caput dose can be noticed, but the increasing number of investigations has determined a net increase of the annual collective dose. High doses of radiation are cumulated from Computed Tomography investigations. An integrated system for radiation safety of the patients investigated by radiological imaging methods, based on smart cards and Public Key Infrastructure allow radiation absorbed dose data storage.

A ladder ellipse problem

Subjects: subject: Classical Analysis and ODEs (math.CA)

subject: 26A06

description: We consider a problem similar to the well-known ladder box problem, but where the box is replaced by an ellipse. A ladder of a given length, $s$, with ends on the positive x and y axes, is known to touch an ellipse that lies in the first quadrant and is tangent to the positive x and y axes. We then want to find the height of the top of the ladder above the floor. We show that there is a value, $s = s_0$, such that there is only one possible position of the ladder, while if $s > s_0$, then there are two different possible positions of the ladder. Our solution involves solving an equation which is equivalent to solving a 4th degree polynomial equation.

description: We show that if $T=H+iK$ is the Cartesian decomposition of $T\in \mathbb{B(\mathscr{H})}$, then for $α,β\in \mathbb{R}$, $\sup_{α^{2}+β^{2}=1}\Vert αH+βK\Vert =w(T)$. We then apply it to prove that if $A,B,X\in \mathbb{B(\mathscr{H})}$ and $0\leq mI\leq X$, then \begin{align*} m\Vert \mbox{Re}(A)-\mbox{Re}(B)\Vert & \leq w(\mbox{Re}(A)X-X\mbox{Re}(B)) \\ & \leq \frac{1}{2}\sup_{θ\in \mathbb{R}}\left\Vert (AX-XB)+e^{iθ}(XA-BX)\right\Vert \\ & \leq \frac{\Vert AX-XB\Vert +\Vert XA-BX\Vert }{2}, \end{align*} where $\mbox{Re}(T)$ denotes the real part of an operator $T$. A refinement of the triangle inequality is also shown.

Predictors of literacy practices in rural African American families

Year: 2012

description: The current study examines the nature of literacy practices in rural African American families. Hierarchical regression analyses are used to examine a number of demographic variables and their possible influence of the frequency of literacy practices in these families. Specifically, this study examines maternal, child, and household structure variables and their relation to child, joint mother-child, and maternal literacy practices. In contrast to many prior studies of low-income minority families, results reveal that these families are frequently engaged in a variety of literacy practices and that children's language skills are on target for their age. Furthermore, maternal employment and child language skills are found to be predictive of child literacy practices, while maternal education and child language skills are predictive of joint literacy practices. Markers of socioeconomic status are not predictive of literacy practices in this sample. The study concludes with a discussion of implications and directions for future research.
Radiative Seesaw-type Mechanism of Fermion Masses and Non-trivial Quark Mixing

description: We propose a predictive inert 2 Higgs doublet model, where the Standard Model (SM) symmetry is extended by $S_{3}\otimes Z_{2}\otimes Z_{12}$ and the field content is enlarged by extra scalar fields, charged exotic fermions and two heavy right-handed Majorana neutrinos. The charged exotic fermions generate a nontrivial quark mixing and provide one-loop-level masses for the first- and second-generation charged fermions. The masses of the light active neutrinos are generated from a one loop-level radiative seesaw mechanism. Our model successfully explains the observed SM fermion mass and mixing pattern.

description: [FeFe] hydrogenases are highly efficient catalysts for reversible dihydrogen evolution. H2 turnover involves different catalytic intermediates including a recently characterized hydride state of the active site (H-cluster). Applying cryogenic infrared and electron paramagnetic resonance spectroscopy to an [FeFe] model hydrogenase from Chlamydomonas reinhardtii (CrHydA1), we have discovered two new hydride intermediates and spectroscopic evidence for a bridging CO ligand in two reduced H-cluster states. Our study provides novel insights into these key intermediates, their relevance for the catalytic cycle of [FeFe] hydrogenase, and novel strategies for exploring these aspects in detail.
