Authorship and Contemporary Hollywood Franchise Cinema
Creators: name: Liu, Zhiyao
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: This study focuses on the context of contemporary Hollywood franchise cinema to explore the use, and reconstruction, of the concept of authorship alongside commercial filmmaking. This thesis comprises three chapters that analyse three case studies, including Peter Jackson and the Middle-earth franchise with which he is closely associated, J.J. Abrams who was trusted to take charge of the reboot franchises Star Wars and Star Trek, and the Marvel Cinematic Universe that has been carefully created by Marvel Studios. The idea of the film author is integral to the marketing strategy of franchise films, even though they are multi-authored texts. This context influences the way in which the authorial status of relevant directors, film studios, or other filmmakers involved in the franchise, is established. Through a wide-ranging analysis of film reviews, film making-of materials, and film texts, as well as an integrative discussion of the idea of stardom and authorship, this thesis presents a detailed account of how authorship functions within franchise cinema. I argue that the context of the franchise can provide a close environment for establishing a recognizable authorial status similar to film auteur, but also distinctly different in that it does not rely on artistic value, which introduces a new concept of the post-auteur film author. Authorship is attributed, depending on the requirements of the franchise, to a designated representative – not necessarily a single figure. However, there are contradictions and instabilities that emerge through this process as the status of the author is tied to the success of the franchise, furthermore, the author may not be a fixed figure as long-running franchises offer the opportunity for inheritance of authorial control. Authorship remains a continued concern in film studies and filmmaking, but the idea of the author is not fixed. Therefore, this thesis presents the idea of the franchise author to discuss authorship within franchise cinema.
Photonics and transport in bulk heterojunction organic solar cells
Creators: name: Tumbleston, John R.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: In this thesis, the groundwork is established for a new type of bulk heterojunction (BHJ) organic solar cell geometry that has photonic crystal (PC) photoactive layers. This design is motivated by the need to improve light absorption without increasing active layer thickness, which for many BHJ systems, degrades electrical performance. It is demonstrated that with the right choice of materials and cell dimensions, quasiguided or resonant modes are excited near the band edge of a variety of BHJ blends to enhance absorption. Resonant modes are predicted by first developing a scattering matrix optical model and then observed in wavelength-, polarization-, and angular-dependent reflection and photocurrent measurements. PC cells are fabricated using a facile nanopatterning technique, where highly ordered arrays of submicron features are constructed over large areas in a single step. Optical and electrical function of this new cell architecture is fully explored in this thesis. Through optical measurements and modeling, PC devices show clear enhancements in light absorption. On the other hand, the impact of the nonplanar geometry on electrical performance is not as easily deduced due to the multitude of electrical processes that lead to photocurrent generation. First, the electrical properties of the electron transporting layer that interfaces with the BHJ nanopattern and provides optical contrast in the PC greatly affect parasitic resistances in the solar cell. By including resistance losses in a drift/diffusion numerical model that describes electrical performance, it is shown that these losses greatly influence fundamental steps leading to photocurrent generation. This is confirmed with experiment by comparing two BHJ material systems that have different affinities for exciton separation. Second, significant levels of free carrier recombination are predicted by the electro-optical model due to the relatively long transport paths in the nanopattern features. To test this prediction, an experimental technique is developed to measure the transport lengths of photogenerated electrons and holes in BHJ solar cells. It is found that transport lengths of positive and negative carriers are mismatched and helps explain both PC electrical performance and recent conflicting results of planar BHJ solar cells in the literature.

description: Water isotopes (δ18O, δ2H) were systematically monitored in two river catchments to investigate the isotopic spatiotemporal variation and the differences between them. The Pinios River Basin (PRB) exhibited lower average δ18O and δ2H values (−7.9‰ and −50.8‰, respectively) compared to the Evrotas River Basin (ERB) (−6.5‰ and −38.2‰, respectively) but higher in range (3.3‰ vs 1.2‰ for δ18O, respectively). The Bayesian modelling results showed higher groundwater contribution in the PRB (25–50%) than in the ERB (15–35%) relative to precipitation during the wet period. The isotopic spatial variability was attributed to the influence of local precipitation, evaporation and additional flow pathways (e.g. soil water). The correlation analysis showed that the isotopic composition is controlled by the catchment altitude, slope and discharge. This study highlights the catchment physiographic control on the isotopic composition of rivers, which can support strategies for better water resources management.

description: By using the general triaxial rotor model (TRM) and the phonon-configuration mixing scheme within an anharmonic-vibrator(AHV) framework, a series of global correlations between electromagnetic properties of nuclear $2^+_1$ and $2^+_2$ states are analytically established. The correlations from both models can roughly describe the experimental data involving quadrupole collectivity with few exceptions. Furthermore, there seems to be a robust orthogonal transformation between the AHV and TRM bases for realistic nuclear systems, suggesting that the two models may in fact be describing the collective features of nuclear low-lying states in similar model spaces.

Understanding the Role of Reactance to Pictorial Warnings on Cigarette Packs
Creators: name: Hall, Marissa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background. Pictorial cigarette pack warnings may be less effective if they elicit reactance, a motivation to resist a perceived threat to freedom. This dissertation developed and validated a brief version of the Reactance to Health Warnings Scale (RHWS). The dissertation also sought to determine the mechanisms by which pictorial warnings elicit stronger quit intentions and subsequent quit attempts, and whether reactance weakened the effect of the warnings. Methods. To develop the Brief RHWS and to test mediation, I used data from a trial that randomly assigned 2,149 adult US smokers in 2014 and 2015 to receive pictorial warnings or text-only warnings on their cigarette packs for four weeks. To further evaluate the brief RHWS, I randomly assigned US adults (n=1,413) to view pictorial or text warnings on digital images of cigarette packs. Results. The three-item Brief RHWS had good internal consistency and test-retest reliability. The scale correlated with higher trait reactance (β=.32, p<.001) and exposure to pictorial warnings (β=.21, p<.001), supporting its convergent validity. With respect to predictive validity, the Brief RHWS was associated with lower perceived message effectiveness, lower quit intentions, greater avoidance of the warnings, and more cigarettes smoked per day (all p<.05). Pictorial warnings produced stronger quit intentions (p<.05) which were associated with a greater likelihood of making a quit attempt (p<.001). Negative affect toward the warnings mediated the effect of pictorial warnings on quit intentions (mediated effect=.25, p<.001), whereas message reactance suppressed the effect (mediated effect=-.06, p<.001). Negative affect was associated with greater perceived likelihood of harm from smoking and anticipated regret of continuing to smoke, which were in turn associated with stronger quit intentions (all p<.05). Conclusion. The Brief RHWS can aid in the development of persuasive messages. Pictorial warnings elicited greater quit intentions, an effect that was stronger after accounting for message reactance. Negative affect appears to be a key mechanism by which pictorial cigarette pack warnings exert their effect on smoking-related cognitions and behaviors. Moreover, pictorial warnings changed risk appraisals and quit intentions indirectly through negative affect.

Zwei der Leitfragen sind, wie sich die Nachrichtenflüsse in Singapur entwickelt haben und ob die Idee einer "Neuen Weltinformationsordnung" immer noch taugt, die Nachrichtenflüsse dort "ausgewogener und effizienter" zu machen. Die These ist, dass die Nachrichtenflüsse in Singapur in den vergangenen Dekaden zwar effizienter, aber nicht ausgewogener wurden. Die Dissertation schließt damit, dass es sich nach wie vor lohnt, über die Unausgewogenheit in den Nachrichtenflüssen dort zu diskutieren, wenngleich die Idee einer "Neuen Weltinformationsordnung" an sich unrealistisch und inzwischen veraltet ist.
description: The subject of this dissertation is the development of news flows in Singapore between 1965 and 2000 in context with the discussions regarding the "New World Information Order". Two of the main questions are how the news flows have developed in Singapore and whether the idea of a "New World Information Order" is still useful to make the news flows there "more just and more efficient". The thesis is that the news flows in Singapore have become more efficient, but not more just in the past several decades. The dissertation concludes that it is still worth discussing the imbalances in the news flows there, even though the idea of the "New World Information Order" itself is unrealistic and outdated now.

description: Coset constructions of $\mathcal{W}$-algebras have many applications, and were recently given for principal $\mathcal{W}$-algebras of $A$, $D$, and $E$ types by Arakawa together with the first and third authors. In this paper, we give coset constructions of the large and small $N=4$ superconformal algebras, which are the minimal $\mathcal{W}$-algebras of $\mathfrak{d}(2,1;a)$ and $\mathfrak{psl}(2|2)$, respectively. From these realizations, one finds a remarkable connection between the large $N=4$ algebra and the diagonal coset $C^{k_1, k_2} = \text{Com}(V^{k_1+k_2}(\mathfrak{sl}_2), V^{k_1}(\mathfrak{sl}_2) \otimes V^{k_2}(\mathfrak{sl}_2))$, namely, as two-parameter vertex algebras, $C^{k_1, k_2}$ coincides with the coset of the large $N=4$ algebra by its affine subalgebra. We also show that at special points in the parameter space, the simple quotients of these cosets are isomorphic to various $\mathcal{W}$-algebras. As a corollary, we give new examples of strongly rational principal $\mathcal{W}$-algebras of type $C$ at degenerate admissible levels.

description: Pre-pregnancy obesity is an established risk factor for adverse sex-specific cardiometabolic health in offspring. Epigenetic alterations, such as in DNA methylation (DNAm), are a hypothesized link; however, sex-specific epigenomic targets remain unclear. Leveraging data from the Newborn Epigenetics Study (NEST) cohort, linear regression models were used to identify CpG sites in cord blood leukocytes associated with pre-pregnancy obesity in 187 mother-female and 173 mother-male offsprings. DNAm in cord blood was measured using the Illumina HumanMethylation450k BeadChip. Replication analysis was conducted among the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Associations between pre-pregnancy obesity-associated CpG sites and offspring BMI z-score (BMIz) and blood pressure (BP) percentiles at 4–5-years of age were also examined. Maternal pre-pregnacy obesity was associated with 876 CpGs in female and 293 CpGs in male offspring (false discovery rate <5%). Among female offspring, 57 CpG sites, including the top 18, mapped to the TAPBP gene (range of effect estimates: −0.83% decrease to 4.02% increase in methylation). CpG methylation differences in the TAPBP gene were also observed among males (range of effect estimates: −0.30% decrease to 2.59% increase in methylation). While technically validated, none of the TAPBP CpG sites were replicated in ALSPAC. In NEST, methylation differences at CpG sites of the TAPBP gene were associated with BMI z-score (cg23922433 and cg17621507) and systolic BP percentile (cg06230948) in female and systolic (cg06230948) and diastolic (cg03780271) BP percentile in male offspring. Together, these findings suggest sex-specific effects, which, if causal, may explain observed sex-specific effects of maternal obesity.

description: We study the propagation of low frequency shallow water waves on a one dimensional flow of varying depth. When taking into account dispersive effects, the linear propagation of long wavelength modes on uneven bottoms excites new solutions of the dispersion relation which possess a much shorter wavelength. The peculiarity is that one of these new solutions has a negative energy. When the flow becomes supercritical, this mode has been shown to be responsible for the (classical) analog of the Hawking effect. For subcritical flows, the production of this mode has been observed numerically and experimentally, but the precise physics governing the scattering remained unclear. In this work, we provide an analytic treatment of this effect in subcritical flows. We analyze the scattering of low frequency waves using a new perturbative series, derived from a generalization of the Bremmer series. We show that the production of short wavelength modes is governed by a complex value of the position: a complex turning point. Using this method, we investigate various flow profiles, and derive the main characteristics of the induced spectrum.

A common misapplication of statistical inference: nuisance control with null-hypothesis significance tests

Year: 2016
Subjects: subject: Methodology (stat.ME)

description: Experimental research on behavior and cognition frequently rests on stimulus or subject selection where not all characteristics can be fully controlled, even when attempting strict matching. For example, when contrasting patients to controls, variables such as intelligence or socioeconomic status are often correlated with patient status. Similarly, when presenting word stimuli, variables such as word frequency are often correlated with primary variables of interest. One procedure very commonly employed to control for such nuisance effects is conducting inferential tests on confounding stimulus or subject characteristics. For example, if word length is not significantly different for two stimulus sets, they are considered as matched for word length. Such a test has high error rates and is conceptually misguided. It reflects a common misunderstanding of statistical tests: interpreting significance not to refer to inference about a particular population parameter, but about 1. the sample in question, 2. the practical relevance of a sample difference (so that a nonsignificant test is taken to indicate evidence for the absence of relevant differences). We show inferential testing for assessing nuisance effects to be inappropriate both pragmatically and philosophically, present a survey showing its high prevalence, and briefly discuss an alternative in the form of regression including nuisance variables.

description: Any glance at education in New Zealand right now reveals a multitude of issues. In the schooling sector the declining rates of literacy and numeracy have been in the news, following a 2020 UNICEF report which found that only 64.6% of Aotearoa New Zealand 15-year-olds had basic proficiency in reading and maths (Hood and Hughson, 2022). Covid-19 has had a negative impact on students’ wellbeing and also contributed to significant declines in learning, especially for lower decile schools and children in Auckland (Education Review Office, 2021). While students’ wellbeing has improved somewhat in 2023, the loss of learning is still significant, with more than half of principals reporting concerns with writing, and growing behavioural issues and inequalities in student achievement (Education Review Office, 2023).

description: Based on the Padmanabhan's proposal, the accelerated expansion of the universe can be driven by the difference between the surface and bulk degrees of freedom in a region of space, described by the relation $dV/dt=N_{sur}-N_{bulk}$ where $N_{sur}$ and $N_{bulk}=-N_{em}+N_{de}$ are the degrees of freedom assigned to the surface area and the matter-energy content inside the bulk such that the indexes $"em"$ and $"de"$ represent energy-momentum and dark energy, respectively. In the present work, the dynamical effect of the Weyssenhoff perfect fluid with intrinsic spin and its corresponding spin degrees of freedom in the framework of Einstein-Cartan (EC) theory are investigated. Based on the modification of Friedmann equations due to the spin-spin interactions, a correction term for the Padmanabhan's original relation $dV/dt=N_{sur}+N_{em}-N_{de}$ including the number of degrees of freedom related to this spin interactions is obtained through the modification in $N_{bulk}$ term as $N_{bulk}=-N_{em}+N_{spin}+N_{de}$ leading to $dV /d t=N_{sur}+N_{em}-N_{spin} -N_{de}$ in which $N_{spin}$ is the corresponding degrees of freedom related to the intrinsic spin of the matter content of the universe. Moreover, the validity of the unified first law and the generalized second law of thermodynamics for the Einstein-Cartan cosmos are investigated. Finally, by considering the covariant entropy conjecture and the bound resulting from the emergent scenario, a total entropy bound is obtained. Using this bound, it is shown that the for the universe as an expanding thermodynamical system, the total effective Komar energy never exceeds the square of the expansion rate with a factor of $\frac{3}{4π}$.

description: People’s stubborn self-identities can bias or constrain how they respond to a health message. The present study proposed and tested an alternative tactic that may overcome the constraints of people’s self-views that reduce the effectiveness of the persuasive message: the mental simulation of becoming possible selves. The procedure of this mental simulation is as follow: during the mental simulation, people imagine becoming their best possible selves with positive traits (e.g., confidence and discipline) in the present or in the future time. To enhance this simulation effect for the future time condition, participants saw the photos of their own faces that are manipulated to look older by a face manipulation software. In turn, they are encouraged to read a health message as their imagined selves. In this way, the author examined to what extent people can read the health message in a new light or in a way that is less limited by their actual self-views. Also, the author examined how the experience of the mental simulation can influence people’s actual health behaviors. To theoretically and empirically examine the mechanisms of the proposed alternative tactic, the current study put forth and tested a theoretical model. The proposed model predicts how the metal simulation of identity shifts can influence people’s cognitive, emotional, and behavioral responses to the health message exposed to them during the mental simulation. Further, the model explicates how the experience of the simulation or imagination can influence people’s actual behavioral intentions. The results of an online experiment provide four core findings. First, the simulation of becoming the positive self increased the perceived personal relevance of the health message during the mental simulation. Secondly, the imagined positive self in the present time showed the stronger effect on the perceived personal relevance than the imagined positive self in the future time. Thirdly, the increased perceived relevance increased the simulated behavioral intention indexed by people’s self-reports about how much they would engage in the health behaviors as their imagined selves in response to the health message. Finally, the higher the simulated intention the higher the actual intention toward the health behaviors.

description: We investigate the maximum rates for transmitting quantum information, distilling entanglement, and distributing secret keys between a sender and a receiver in a multipoint communication scenario, with the assistance of unlimited two-way classical communication involving all parties. First we consider the case where a sender communicates with an arbitrary number of receivers, so called quantum broadcast channel. Here we also provide a simple analysis in the bosonic setting where we consider quantum broadcasting through a sequence of beamsplitters. Then, we consider the opposite case where an arbitrary number of senders communicate with a single receiver, so called quantum multiple-access channel. Finally, we study the general case of all-in-all quantum communication where an arbitrary number of senders communicate with an arbitrary number of receivers. Since our bounds are formulated for quantum systems of arbitrary dimension, they can be applied to many different physical scenarios involving multipoint quantum communication.

description: Primality generation is the cornerstone of several essential cryptographic systems. The problem has been a subject of deep investigations, but there is still a substantial room for improvements. Typically, the algorithms used have two parts trial divisions aimed at eliminating numbers with small prime factors and primality tests based on an easy-to-compute statement that is valid for primes and invalid for composites. In this paper, we will showcase a technique that will eliminate the first phase of the primality testing algorithms. The computational simulations show a reduction of the primality generation time by about 30% in the case of 1024-bit RSA key pairs. This can be particularly beneficial in the case of decentralized environments for shared RSA keys as the initial trial division part of the key generation algorithms can be avoided at no cost. This also significantly reduces the communication complexity. Another essential contribution of the paper is the introduction of a new one-way function that is computationally simpler than the existing ones used in public-key cryptography. This function can be used to create new random number generators, and it also could be potentially used for designing entirely new public-key encryption systems.

Properties of an R2 statistic for fixed effects in the linear mixed model for longitudinal data
Creators: name: Matuszewski, Jeanine M.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The R2 statistic has become a widely used tool when analyzing data in the linear univariate setting. Many R2 statistics for the linear mixed model exist but their properties are not well established. The purpose of this dissertation is to examine the properties and performance of R2[beta] for fixed effects in the linear mixed model. Two approaches are considered in deriving approximations for the mean and variance of R2[beta] under the null and alternative hypotheses which include using the Beta distribution and a Taylor series approximation. Test statistics based on these two approximations of the mean and variance are proposed and compared to the overall F test for fixed effects in the linear mixed model. Using simulations, the Type I error rate of the proposed R2[beta] test statistics derived from the Beta distribution was equivalent to the Type I error rate for the overall F test. The Type I error rates for the test statistic based on the Taylor series approximation moments were slightly inflated. The impact of covariance structure misspecification, estimation technique, and denominator degrees of freedom method on the asymptotic properties of R2[beta] are explored. For the simulation studies examined, the estimation technique does not impact the values of R2[beta]. The values and asymptotic properties of R2[beta] using Kenward-Roger, containment and Satterthwaite methods are greatly impacted by covariance structure misspecification whereas R2[beta] using the residual method is not. Simulations illustrate the impact of underspecification of the covariance structure as compound symmetric when the true structure is more complex. The asymptotic R2[beta]'s for the underspecified models using Kenward-Roger degrees of freedom are smaller than the true asymptotic R2[beta]'s. Conversely, the asymptotic R2[beta]'s for the underpecified models using residual methods are larger than the true asymptotic R2[beta]. The semi-parital R2[beta] for the four denominator degrees of freedom are computed and compared to the corresponding model R2[beta] in both a real world example and simulation study. The semi-partial R2[beta] using residual degrees of freedom never exceeded the model R2[beta], but the semi-partial R2[beta] using the other three methods sometimes exceeded the model R2[beta]. R2[beta] is also evaluated as a fixed effects model selection tool. The performance of R2[beta] is poor; so an adjusted R2[beta] is created for purposes of fixed effects model selection. The adjusted R2[beta] using residual degrees of freedom outperformed the adjusted R2[beta] defined using the other methods.
On the crystalline structure of orthorhombic SrRuO$_3$: A benchmark study of DFT functionals

description: By investigating the crystalline structure of ground-state orthorhombic SrRuO$_3$, we present a benchmark study of some of the most popular density functional theory (DFT) approaches from the local density approximation (LDA), generalized-gradient approximation (GGA), and hybrid functional families. Recent experimental success in stabilizing tetragonal and monoclinic phases of SrRuO$_3$ at room temperature sheds a new light on the ability to accurately describe geometry of this material by applying first-principles calculations. Therefore, our work is aimed to analyse the performance of different DFT functionals and provide some recommendations for future research of SrRuO$_3$. A comparison of the obtained results to the low-temperature experimental data indicates that revised GGAs for solids are the best choice for the lattice constants and volume due to their nice accuracy and low computational cost. However, when tilting and rotation angles appear on the scene, a combination of the revised GGAs with the hybrid scheme becomes the most preferable option. It is important to note that a worse performance of LDA functional is somewhat compensated by its realistic reproduction of electronic and magnetic structure of SrRuO$_3$, making it a strong competitor if the physical features are also taken into account.

Medical poems and the romantic rise of disciplinarity
Creators: name: Rogers, Kathleen Béres
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Traditionally, Romanticism has been viewed as a movement at odds with early nineteenth-century scientific developments. By examining Romantic-era philosophies of literature and science through the lens of medical poetry by both canonical and unpublished British and American writers, I argue that medical poetry (poetry by medical practitioners and patients) significantly contributed to the rise of medicine. Through its emphasis on status, sympathy, clinical detachment, and patients' agency, it laid down many of the discipline's epistemological foundations. While critics have examined poems by well-known medical practitioners like John Keats and George Crabbe, mine is the first comprehensive scholarly analysis of this genre.

description: Recently it has been shown that quantum fields can be regular on the inner, Cauchy horizon of a rotating BTZ black hole, which appears to indicate a failure of strong cosmic censorship. We argue that, instead, what these results imply is that the inner horizon remains non-singular when leading-order backreaction of the quantum fields is computed, but, after next-order backreaction is accounted for, it will become singular. Then, strong cosmic censorship will be enforced in the BTZ black hole. We support our claims using a four-dimensional holographic dual of the system, which connects the instability of the inner horizon of the BTZ black hole to that of Kerr-type black holes.

description: The ability to probe symmetry breaking transitions on their natural time scales is one of the key challenges in nonequilibrium physics. Stripe ordering represents an intriguing type of broken symmetry, where complex interactions result in atomic-scale lines of charge and spin density. Although phonon anomalies and periodic distortions attest the importance of electron-phonon coupling in the formation of stripe phases, a direct time-domain view of vibrational symmetry breaking is lacking. We report experiments that track the transient multi-THz response of the model stripe compound La$_{1.75}$Sr$_{0.25}$NiO$_{4}$, yielding novel insight into its electronic and structural dynamics following an ultrafast optical quench. We find that although electronic carriers are immediately delocalized, the crystal symmetry remains initially frozen - as witnessed by time-delayed suppression of zone-folded Ni-O bending modes acting as a fingerprint of lattice symmetry. Longitudinal and transverse vibrations react with different speeds, indicating a strong directionality and an important role of polar interactions. The hidden complexity of electronic and structural coupling during stripe melting and formation, captured here within a single terahertz spectrum, opens new paths to understanding symmetry breaking dynamics in solids.

description: We solve the local lifting problem for the alternating group A_4, thus showing that it is a local Oort group. Specifically, if k is an algebraically closed field of characteristic 2, we prove that every A_4-extension of k[[s]] lifts to characteristic zero. As a consequence, every A_4-branched cover of smooth projective curves in characteristic 2 lifts to characteristic zero.

A Comparison of Gluteus Medius, Gluteus Maximus, and Hamstrings Activation during Five Commonly Used Plyometric Exercises

description: Anterior Cruciate Ligament (ACL) injuries occur frequently in athletics, and plyometric exercises may aid in preventing these injuries. The purpose of this study was to determine which plyometric exercises produce the greatest activation of the gluteal and hamstrings muscles and the medial-to-lateral hamstrings activation ratio. Forty-one subjects performed 5 plyometric exercises while muscle activity was recorded. Subjects displayed the most hamstrings and gluteal muscle activity during the single-leg sagittal plane hurdle hops, the least muscle activity during the 180o hops, and the greatest preparatory medial-to-lateral hamstrings ratio during the double-leg sagittal plane hurdle hops and split squat jumps. Therefore, 180o hops are not as effective as other plyometric exercises at targeting gluteal and hamstrings activation. Frontal or sagittal plane exercises are needed to enhance medial-to-lateral hamstrings activation and gluteal activation, respectively. Future research should examine the effects of frontal versus sagittal plane plyometric exercise intervention programs on knee biomechanics.

description: New physics realized above the electroweak scale can be encoded in a model independent way in the Wilson coefficients of higher dimensional operators which are invariant under the Standard Model gauge group. In this article, we study the matching of the $SU(3)_C \times SU(2)_L \times U(1)_Y$ gauge invariant dim-6 operators on the standard $B$ physics Hamiltonian relevant for $b \to s$ and $b\to c$ transitions. The matching is performed at the electroweak scale (after spontaneous symmetry breaking) by integrating out the top quark, $W$, $Z$ and the Higgs particle. We first carry out the matching of the dim-6 operators that give a contribution at tree level to the low energy Hamiltonian. In a second step, we identify those gauge invariant operators that do not enter $b \to s$ transitions already at tree level, but can give relevant one-loop matching effects.

The Subspace Voyager: Exploring High-Dimensional Data along a Continuum of Salient 3D Subspaces

description: Analyzing high-dimensional data and finding hidden patterns is a difficult problem and has attracted numerous research efforts. Automated methods can be useful to some extent but bringing the data analyst into the loop via interactive visual tools can help the discovery process tremendously. An inherent problem in this effort is that humans lack the mental capacity to truly understand spaces exceeding three spatial dimensions. To keep within this limitation, we describe a framework that decomposes a high-dimensional data space into a continuum of generalized 3D subspaces. Analysts can then explore these 3D subspaces individually via the familiar trackball interface, but using additional facilities to smoothly transition to adjacent subspaces for expanded space comprehension. Since the number of such subspaces suffers from combinatorial explosion, we provide a set of data-driven subspace selection and navigation tools which can guide users to interesting subspaces and views. A subspace trail map allows users to manage the explored subspaces, and also helps them navigate within and across any higher-dimensional subspaces identified by clustering. Both trackball and trail map are each embedded into a word cloud of attribute labels, sized according to the relevance of the associated data dimensions in the currently selected subspace. Finally, a view gallery helps users keep their bearings and return to interesting subspaces and views. We demonstrate our system via several use cases in a diverse set of application areas, such as cluster analysis and refinement, information discovery, and supervised training of classifiers.

description: Given a graph $G=(V,E)$ with $V=\{1,\ldots,n\}$, we place on every vertex a token $T_1,\ldots,T_n$. A swap is an exchange of tokens on adjacent vertices. We consider the algorithmic question of finding a shortest sequence of swaps such that token $T_i$ is on vertex $i$. We are able to achieve essentially matching upper and lower bounds, for exact algorithms and approximation algorithms. For exact algorithms, we rule out any $2^{o(n)}$ algorithm under the ETH. This is matched with a simple $2^{O(n\log n)}$ algorithm based on a breadth-first search in an auxiliary graph. We show one general $4$-approximation and show APX-hardness. Thus, there is a small constant $δ>1$ such that every polynomial time approximation algorithm has approximation factor at least $δ$. Our results also hold for a generalized version, where tokens and vertices are colored. In this generalized version each token must go to a vertex with the same color.
