Chipped Stone Technology and Agricultural Households in the Moche Valley, Peru
Creators: name: Surridge, Evan William
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: Stone tool technology has received little attention in the study of complex societies in the Andes, as archaeologists have focused heavily on elite crafts and architecture. Such tools, however, offer an important means of assessing the labor roles of particular social groups. This thesis examines lithic assemblages dating to the Early Intermediate Period (ca. 400 BC - AD 600) from Peru's middle Moche Valley and assesses variability in elite domestic economies. During an occupation of the valley by highland colonists, elite households were intensely involved in agricultural labor, as evidenced by high discard rates of stone hoes. These households may also have produced surplus tools for exchange. By the Middle Moche phase, middle valley elites and their retainers were only marginally involved in agricultural labor. Instead, their domestic economies focused on mobilizing the labor of other households through the redistribution of crafts and foodstuffs such as chicha.
String Stability towards Leader thanks to Asymmetric Bidirectional Controller

description: This paper deals with the problem of string stability of interconnected systems with double-integrator open loop dynamics (e.g.~acceleration-controlled vehicles). We analyze an asymmetric bidirectional linear controller, where each vehicle is coupled solely to its immediate predecessor and to its immediate follower with different gains in these two directions. We show that in this setting, unlike with unidirectional or symmetric bidirectional controllers, string stability can be recovered when disturbances act only on a small ($N$-independent) set of leading vehicles. This improves existing results from the literature with this assumption. We also indicate that string stability with respect to arbitrarily distributed disturbances cannot be achieved with this controller.

description: This preprint has been reviewed and recommended by Peer Community In Evolutionary Biology (http://dx.doi.org/10.24072/pci.evolbiol.100036). Approximate Bayesian computation (ABC) has grown into a standard methodology that manages Bayesian inference for models associated with intractable likelihood functions. Most ABC implementations require the preliminary selection of a vector of informative statistics summarizing raw data. Furthermore, in almost all existing implementations, the tolerance level that separates acceptance from rejection of simulated parameter values needs to be calibrated. We propose to conduct likelihood-free Bayesian inferences about parameters with no prior selection of the relevant components of the summary statistics and bypassing the derivation of the associated tolerance level. The approach relies on the random forest methodology of Breiman (2001) applied in a (non parametric) regression setting. We advocate the derivation of a new random forest for each component of the parameter vector of interest. When compared with earlier ABC solutions, this method offers significant gains in terms of robustness to the choice of the summary statistics, does not depend on any type of tolerance level, and is a good trade-off in term of quality of point estimator precision and credible interval estimations for a given computing time. We illustrate the performance of our methodological proposal and compare it with earlier ABC methods on a Normal toy example and a population genetics example dealing with human population evolution. All methods designed here have been incorporated in the R package abcrf (version 1.7) available on CRAN.

Improper coloring of graphs on surfaces
Creators: name: Choi, Ilkyoo
name: Esperet, Louis
Publisher: name: arXiv
Year: 2016
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: A graph $G$ is $(d_1,\ldots,d_k)$-colorable if its vertex set can be partitioned into $k$ sets $V_1,\ldots,V_k$, such that for each $i\in\{1, \ldots, k\}$, the subgraph of $G$ induced by $V_i$ has maximum degree at most $d_i$. The Four Color Theorem states that every planar graph is $(0,0,0,0)$-colorable, and a classical result of Cowen, Cowen, and Woodall shows that every planar graph is $(2,2,2)$-colorable. In this paper, we extend both of these results to graphs on surfaces. Namely, we show that every graph embeddable on a surface of Euler genus $g>0$ is $(0,0,0,9g-4)$-colorable and $(2,2,9g-4)$-colorable. Moreover, these graphs are also $(0,0,O(\sqrt{g}),O(\sqrt{g}))$-colorable and $(2,O(\sqrt{g}),O(\sqrt{g}))$-colorable. We also prove that every triangle-free graph that is embeddable on a surface of Euler genus $g$ is $(0, 0, O(g))$-colorable. This is an extension of Grötzsch's Theorem, which states that triangle-free planar graphs are $(0, 0, 0)$-colorable. Finally, we prove that every graph of girth at least 7 that is embeddable on a surface of Euler genus $g$ is $(0,O(\sqrt{g}))$-colorable. All these results are best possible in several ways as the girth condition is sharp, the constant maximum degrees cannot be improved, and the bounds on the maximum degrees depending on $g$ are tight up to a constant multiplicative factor.

description: There is resurging interest, in statistics and machine learning, in solvers for ordinary differential equations (ODEs) that return probability measures instead of point estimates. Recently, Conrad et al. introduced a sampling-based class of methods that are 'well-calibrated' in a specific sense. But the computational cost of these methods is significantly above that of classic methods. On the other hand, Schober et al. pointed out a precise connection between classic Runge-Kutta ODE solvers and Gaussian filters, which gives only a rough probabilistic calibration, but at negligible cost overhead. By formulating the solution of ODEs as approximate inference in linear Gaussian SDEs, we investigate a range of probabilistic ODE solvers, that bridge the trade-off between computational cost and probabilistic calibration, and identify the inaccurate gradient measurement as the crucial source of uncertainty. We propose the novel filtering-based method Bayesian Quadrature filtering (BQF) which uses Bayesian quadrature to actively learn the imprecision in the gradient measurement by collecting multiple gradient evaluations.

Revisiting the first year inventory with a dimensional approach to assess the predictive value of infant attention behaviors
Creators: name: Stephens, Rebecca
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Research supports a strong relationship between early attention behaviors and neurological attention networks and later cognitive and social capabilities, including impairments associated with autism spectrum disorder (ASD). The First Year Inventory (FYI) was designed to flag 12-month-olds at risk for a diagnosis of ASD. The goal of the current study was to develop new constructs from FYI items that reflect aspects of attention, through a comprehensive literature review of behavioral and neurological correlates of infant attention, feedback from other researchers, statistical analyses and associations between the new constructs and clinical outcome data. We operationalized three new constructs of attention: responding to attention coordination (RAC), initiating attention coordination (IAC) and sensory and attentional engagement (SAE). Cronbach's alpha analyses indicated good internal consistency, and regression analyses showed a significant relationship between scores on these new constructs at 12 months and ASD symptom severity at age three.

description: We consider equatorial motion of particles in the ergoregion of generic axially symmetric rotating black holes. We introduce the notion of zero energy observers (ZEOs) as counterparts to known zero angular observers (ZAMOs). It is shown that the trajectory of a ZEO has precisely one turning point that lies on the boundary of the ergoregion for photons and inside the ergoregion for massive particles. As a consequence, such trajectories enter the ergosphere from the white hole region under horizon and leave it crossing the horizon again (entering the black hole region). The angular velocity of ZEO does not depend on the angular momentum. For particles with $% E>0$ this velocity is bigger than for a ZEO, for $E<0$ it is smaller. General limitations on the angular momentum are found depending on whether the trajectory lies entirely inside the ergoregion, bounces back from the boundary or intersects it. These results generalize the recent observations made in A. A. Grib, Yu. V. Pavlov, arXiv:1601.02592 for the Kerr metric. We also show that collision between a ZEO and a particle with $E\neq 0$ near a black hole can lead to the unbound energy in the centre of mass thus giving a special version of the Bañados - Silk - West effect.

description: The pioneering work of Jones and Kauffman unveiled a fruitful relationship between statistical mechanics and knot theory. Recently, Jones introduced two subgroups $\vec{F}$ and $\vec{T}$ of the Thompson groups $F$ and $T$, respectively, together with a procedure that associates an oriented link diagram to any element of these subgroups. Moreover, several specializations of some well-known polynomial link invariants can be seen as functions of positive type on the Thompson groups or the Jones-Thompson subgroups. One important example is provided by suitable evaluations of the Jones polynomial, which are thus associated with certain unitary representations of the groups $\vec{F}$ and $\vec{T}$. Within this framework, we discuss an alternative approach that relies on some partition function interpretation of the Jones polynomial, and also exhibit more examples associated with other link invariants, notably the two-variable Kauffman polynomial and the HOMFLY polynomial. In the unoriented case, extending our previous results, we also show by similar methods that certain evaluations of the Tutte polynomial and of the Kauffman bracket, suitably renormalized, yield functions of positive type on $T$.

description: The Hubble Space Telescope has imaged the central part of M87 over a 10 week span, leading to the discovery of 32 classical novae and nine fainter, likely very slow and/or symbiotic novae. In this first in a series of papers we present the M87 nova finder charts, and the light and color curves of the novae. We demonstrate that the rise and decline times, and the colors of M87 novae are uncorrelated with each other and with position in the galaxy. The spatial distribution of the M87 novae follows the light of the galaxy, suggesting that novae accreted by M87 during cannibalistic episodes are well-mixed. Conservatively using only the 32 brightest classical novae we derive a nova rate for M87: $363_{-45}^{+33}$ novae/yr. We also derive the luminosity-specific classical nova rate for this galaxy, which is $7.88_{-2.6}^{+2.3} /yr/ 10^{10}L_\odot,_{K}$. Both rates are 3-4 times higher higher than those reported for M87 in the past, and similarly higher than those reported for all other galaxies. We suggest that most previous ground-based surveys for novae in external galaxies, including M87, miss most faint, fast novae, and almost all slow novae near the centers of galaxies.

Biopolymer Matrix Enhances Bone Regeneration in Rat Critical Size Skull Defects

Year: 2006

description: Reducing the need for harvesting autologous bone is a major goal of current research. A recently developed collagen/dextran hygrogel scaffold (E-matrixTM) may offer osteoinductive advantages as a biologic polymer for bone repair. This scaffold, by mimicking embryonic extracellular matrix, could promote osteogenesis in the absence of osseoinductive agents. 8.9mm craniotomy defects were created in the parietal bone of 23 Sprague-Dawley rats. In a randomized manner, implants (Collagen only, Collagen/E matrix, Collagen/BMP) were placed onto the defect. Healing was permitted for 2, 4 or 6 weeks. At these timelines BMP treated defects showed good bone repair (26.20%, 42.60% and 22.12% bone fill, respectively). EmatrixTM defects showed equal bone repair at 4 and 6 weeks (40.21 and 22.12% respectively), but reduced bone at 2 weeks (5.08%). Bone repair was incomplete in Collage and saline treated defects. EmatrixTM supported bone repair of critical sized defects. The mechanism of action requires additional investigation.

description: In the framework of the planar and circular restricted three-body problem, we consider an asteroid that orbits the Sun in quasi-satellite motion with a planet. A quasi-satellite trajectory is a heliocentric orbit in co-orbital resonance with the planet, characterized by a non zero eccentricity and a resonant angle that librates around zero. Likewise, in the rotating frame with the planet it describes the same trajectory as the one of a retrograde satellite even though the planet acts as a perturbator. In the last few years, the discoveries of asteroids in this type of motion made the term "quasi-satellite" more and more present in the literature. However, some authors rather use the term "retrograde satellite" when referring to this kind of motion in the studies of the restricted problem in the rotating frame. In this paper we intend to clarify the terminology to use, in order to bridge the gap between the perturbative co-orbital point of view and the more general approach in the rotating frame. Through a numerical exploration of the co-orbital phase space, we describe the quasi-satellite domain and highlight that it is not reachable by low eccentricities by averaging process. We will show that the quasi-satellite domain is effectively included in the domain of the retrograde satellites and neatly defined in terms of frequencies. Eventually, we highlight a remarkable high eccentric quasi-satellite orbit corresponding to a frozen ellipse in the heliocentric frame. We extend this result to the eccentric case (planet on an eccentric motion) and show that two families of frozen ellipses originate from this remarkable orbit.

Development of a Portable Animal Ventilator for Hyperpolarized 129Xe MRI and MRE at 9.4 Tesla
Creators: name: Nestore, Ludovica
Publisher: name: University of Illinois at Chicago
Year: 2023

description: As a non-invasive and powerful method for assessing lung function, hyperpolarized (HP) 129Xe magnetic resonance (MR) imaging is increasingly being utilized in clinical settings to investigate various respiratory conditions. Concurrently, MR elastography (MRE) research holds promise in delivering crucial information regarding lung mechanical properties, particularly density and stiffness. Given the evolving nature of this field, numerous preclinical studies are still required. However, preclinical animal studies involving MRI and MRE encounter challenges such as the necessity for anesthesia, the need for precise delivery of very small tidal volumes (which affects gas administration accuracy), motion artifacts stemming from irregular breathing patterns during spontaneous respiration, and the demand for a high spatial resolution to detect regional changes. To surmount these limitations, this project proposes a portable HP gas ventilator that enables high-resolution 3D imaging of dissolved and gas-phase 129Xe in the lungs, compatible with a 9.4 Tesla MR system. The ventilator incorporates differential pressure transducers and a 3D-printed pneumotachometer, allowing for precise control of tidal volume, breathing cycles, and calibrated positive expiratory pressure in intubated animals. By leveraging low-cost microcontrollers, 3D-printed components, and open-source software, in addition to recapturing expelled HP gases, the overall cost per study is significantly reduced. The device is adaptable for use with various small animals, including rats, mice, guinea pigs, and rabbits, obviating the need for tracheotomy and substantially improving post-study survivability. Anesthesia is integrated into the oxygen supply, enabling prolonged testing durations while minimizing invasiveness. Future advancements will encompass the integration of the forced oscillation technique (FOT), thereby examining whether the combined utilization of MRI, MRE, and FOT can provide enhanced insights into complex lung function

For instance, rating physical attractiveness from 1--5 on dating sites, or papers from 1--10 for conference reviewing. We study the problem of understanding when using a different number of options is optimal. We consider the case when scores are uniform random and Gaussian. We study computationally when using 2, 3, 4, 5, and 10 options out of a total of 100 is optimal in these models (though our theoretical analysis is for a more general setting with $k$ choices from $n$ total options as well as a continuous underlying space). One may expect that using more options would always improve performance in this model, but we show that this is not necessarily the case, and that using fewer choices---even just two---can surprisingly be optimal in certain situations. While in theory for this setting it would be optimal to use all 100 options, in practice this is prohibitive, and it is preferable to utilize a smaller number of options due to humans' limited computational resources. Our results could have many potential applications, as settings requiring entities to be ranked by humans are ubiquitous. There could also be applications to other fields such as signal or image processing where input values from a large set must be mapped to output values in a smaller set.

description: In this paper, a variant of discretization of the van Roosbroeck equations in the equilibrium state with the Composite Discontinuous Galerkin Method for the rectangular domain is discussed. It is based on Symmetric Interior Penalty Galerkin (SIPG) method. The proposed method accounts for lower regularity of the solution on the interfaces of devices' layers. It is shown that the discrete problem is well-defined and that discrete solution is unique. Error estimates are derived. Finally, numerical simulations are presented.

Joint attention in book reading for children with hearing loss
Creators: name: Christensen, Kendra L.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: Children with hearing loss are at risk for delays in the development of language and literacy skills. Recent technological advances in cochlear implants and hearing aids may create more easily accessible language and literacy skills for these children; however, the impact of this technology is still unknown. Strategies targeting improved shared book reading interactions have the potential to have a positive impact on the language and literacy development of children with hearing loss. In this study, a questionnaire was developed that could be utilized to help determine the differences in the home literacy environments of these children, as compared to normal hearing children, to see if there is a need for such interventions and to guide the development of strategic interventions. Overall, this questionnaire was shown to be written at a level that is accessible to families of various educational levels.

description: Recently, the switching between the different charge-ordered phases of 1T-TaS2 has been probed by ultrafast techniques, revealing unexpected phenomena such as "hidden" metastable states and peculiar photoexcited charge patterns. Here, we apply broadband pump-probe spectroscopy with varying excitation energy to study the ultrafast optical properties of 1T-TaS2 in the visible regime. By scanning the excitation energy in the near-IR region we unravel the coupling between different charge excitations and the low-lying charge-density wave state. We find that the amplitude mode of the charge-density wave exhibits strong coupling to a long-lived doublon state that is photoinduced in the center of the star-shaped charge-ordered Ta clusters by the near-IR optical excitation.

Social Origins and Educational Attainment in France: A True Meritocracy?
Creators: name: Shadoian, Vanessa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: In the developed countries, inequality in access to primary education has become essentially non-existent. This is also becoming the case in secondary education, mainly at the lower secondary level, but such inequalities do still exist in upper secondary and higher education, despite the fact that they tend to be decreasing almost everywhere. Thus, contemporary studies in the industrial world are less concerned with issues of access, and increasingly concerned with inequalities in attainment and in educational opportunity, so as to determine the extent of the democratization of access to education. The purpose of this paper is to analyze the changes in inequality in educational opportunity in industrial societies since World War II, specifically in France. I will also analyze the changes in inequality of educational opportunity vis-à-vis immigrants in post-industrial societies and in France.

description: Additional file 3: Fig. S3. Gating strategy T cells in the lamina propria. Live single cells were gated by FSC-A vs. SSC-A. Single cells from lamina propria were gated based on CD45 expression , followed by CD3 to identify T cells. T cells were divided into γδ T cells and non-γδ T cells based on TCR γδ (TCR1) expression, with γδ T cells then sub-divided into three subpopulations. Non-γδ T cells were sub-divided based on CD4 expression. CD4+ and CD4– T cells were then sub-divided into subpopulations based on CD8a or CD8b expression.
Group representations in the homology of 3-manifolds

description: If M is a manifold with an action of a group G, then the homology group H_1(M,Q) is naturally a Q[G]-module, where Q[G] denotes the rational group ring. We prove that for every finite group G, and for every Q[G]-module V, there exists a closed hyperbolic 3-manifold M with a free G-action such that the Q[G]-module H_1(M,Q) is isomorphic to V. We give an application to spectral geometry: for every finite set P of prime numbers, there exist hyperbolic 3-manifolds N and N' that are strongly isospectral such that for all p in P, the p-power torsion subgroups of H_1(N,Z) and of H_1(N',Z) have different orders. We also show that, in a certain precise sense, the rational homology of oriented Riemannian 3-manifolds with a G-action "knows" nothing about the fixed point structure under G, in contrast to the 2-dimensional case. The main geometric techniques are Dehn surgery and, for the spectral application, the Cheeger-Müller formula, but we also make use of tools from different branches of algebra, most notably of regulator constants, a representation theoretic tool that was originally developed in the context of elliptic curves.

Effect of Restricted Hip Flexors on Biomechanical Risk Factors for ACL Injury
Creators: name: Mills, Matthew Edward
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Anterior Cruciate Ligament injuries are devastating on patients and society. It has been theorized that hip flexor restriction may affect muscles distally in the kinetic chain with no supporting literature. We hypothesized that those with hip flexor restriction will display biomechanics linked to ACL injury. Forty subjects completed functional tasks, range of motion measurements, and strength testing of gluteal muscles. Independent t-tests were run to determine the difference between control subjects and those with restricted hip flexors. Subjects with restricted hip flexors were observed to have less dorsiflexion, and less hip abduction and external rotation. There were no differences in gluteal strength. Restricted subjects were observed to have less anterior pelvic tilt at rest, less gluteus maximus activation during squatting, and exhibited differences in kinematics and kinetics during functional tasks. This indicates hip flexor restriction may lead to biomechanics identified as risk factors for ACL injury, and warrants further examination.
The role of international actors in post-conflict Bosnian elections
Creators: name: Hart, Bryan Schrader
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This thesis discusses the role of international actors in the post conflict elections in Bosnia and Herzegovina. It focuses mainly on the role of the Organization for Security and Cooperation in Europe (OSCE) as well as the Office of the High Representative (OHR) in shaping the electoral system and influencing electoral politics through conflict management strategies. The main focus is placed on the entity parliamentary elections in 2000 and 2002 in order to assess the value and success of the conflict management strategies employed as well as the success of the international actors themselves. The thesis concludes that while international actors have been successful in producing a degree of stability in Bosnia since 1995, they have been less successful in reducing the saliency of ethnic politics in elections and consequently the role of the major ethno-nationalist parties in the post-conflict political system.

description: We present combined measurements of the spatially-resolved optical spectrum and the total excited-atom number in an ultracold gas of three-level atoms under electromagnetically induced transparency conditions involving high-lying Rydberg states. The observed optical transmission of a weak probe laser at the center of the coupling region exhibits a double peaked spectrum as a function of detuning, whilst the Rydberg atom number shows a comparatively narrow single resonance. By imaging the transmitted light onto a charge-coupled-device camera, we record hundreds of spectra in parallel, which are used to map out the spatial profile of Rabi frequencies of the coupling laser. Using all the information available we can reconstruct the full one-body density matrix of the three-level system, which provides the optical susceptibility and the Rydberg density as a function of spatial position. These results help elucidate the connection between three-level interference phenomena, including the interplay of matter and light degrees of freedom and will facilitate new studies of many-body effects in optically driven Rydberg gases.
