description: In this paper, we investigate the possible parameter space of Palatini-Horndeski theory with gravitational waves in a spatially flat Universe. We find that if the theory satisfies the following condition: in any spatially flat cosmological background, the tensor gravitational wave speed is the speed of light $c$, then only $S = \int d^4x \sqrt{-g} \big[K(ϕ,X)-G_{3}(ϕ,X){\tilde{\Box}}ϕ+G_{4}(ϕ)\tilde{R}\big]$ is left as the possible action in Palatini-Horndeski theory.

description: Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies. We discuss the present observational data and their implications for theories of the formation and evolution of both dwarf and giant galaxies. The putative dark matter content of these low-surface-brightness systems is of particular interest, as is their chemical evolution. Surveys for new dwarf spheroidals hidden behind the stars of our Galaxy and those which are not bound to giant galaxies may give new clues as to the origins of this unique class of galaxy.

description: Graph signal processing analyzes signals supported on the nodes of a network with respect to a shift operator matrix that conforms to the graph structure. For shift-invariant graph filters, which are polynomial functions of the shift matrix, the filter response is defined by the value of the filter polynomial at the shift matrix eigenvalues. Thus, information regarding the spectral decomposition of the shift matrix plays an important role in filter design. However, under stochastic conditions leading to uncertain network structure, the eigenvalues of the shift matrix become random, complicating the filter design task. In such case, empirical distribution functions built from the random matrix eigenvalues may exhibit deterministic limiting behavior that can be exploited for problems on large-scale random networks. Acceleration filters for distributed average consensus dynamics on random networks provide the application covered in this thesis work. The thesis discusses methods from random matrix theory appropriate for analyzing adjacency matrix spectral asymptotics for both directed and undirected random networks, introducing relevant theorems. Network distribution properties that allow computational simplification of these methods are developed, and the methods are applied to important classes of random network distributions. Subsequently, the thesis presents the main contributions, which consist of optimization problems for consensus acceleration filters based on the obtained asymptotic spectral density information. The presented methods cover several cases for the random network distribution, including both undirected and directed networks as well as both constant and switching random networks. These methods also cover two related optimization objectives, asymptotic convergence rate and graph total variation.
pQCD vs. AdS/CFT Tested by Heavy Quark Energy Loss

Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We predict the charm and bottom quark nuclear modification factors using weakly coupled pQCD and strongly coupled AdS/CFT drag methods. The log(pT/M_Q)/pT dependence of pQCD loss and the momentum independence of drag loss lead to different momentum dependencies for the R_{AA} predictions. This difference is enhanced by examining a new experimental observable, the double ratio of charm to bottom nuclear modification factors, R^{cb}=R^c_{AA}/R^b_{AA}. At LHC the weakly coupled theory predicts R^{cb} goes to 1; whereas the strongly coupled theory predicts R^{cb} .2 independent of pT. At RHIC the differences are less dramatic, as the production spectra are harder, but the drag formula is applicable to higher momenta, due to the lower temperature.

Whole Care+: An integrated health care for the elderly living in their homes
Creators: name: Park, Hyo Ri
Publisher: name: Carnegie Mellon University

Subjects: Design

description: The elderly experience their health getting significantly deteriorated as they age. They suffer not only from chronic diseases but from various geriatric diseases such as high blood pressure, arthritis and cardiovascular disease. Their mental health also retreats creating challenges for the elderly from the loss of short term memory to dementia. Furthermore, after they retire, the elderly’s social network decreases as their social activities are inevitably limited to a small group of people like families and friends. With the face of such impairments in their physical, mental and social health, many elderly cannot help but are being institutionalized or sent to specialized places like nursing homes, which provide them professional care. However, a study indicates that most Americans prefer to stay in their homes as they get older since they can maintain their social connections to neighbors and friends, be close to their medical caregivers in town as well as attain emotional comfort and security with familiar surrounding and environments. On top of that, Americans of all ages value on keeping their ability of independence and autonomy by controlling their lives in general. Various health care-aid devices and services appear to offer specific support to health care activities for the elderly in their homes. However, such aids have more focused only on when the elderly’s health is degraded or on very specific areas such as tracking health data like blood pressure, blood sugar and calorie intakes. The elderly need comprehensive understanding about their health problems, healthy daily habits and timely interactions with their families and caregivers, in order to keep independent living safely in their places. Smart Home technology has much potential to support the elderly’s independent living as well as interactions with others. To better understand this, we conducted a user-centered design project which looks at the management of the elderly’s health enabled by Smart Home technology.

description: A full three-band model for the CuO$_{2}$ plane with inclusion of all essential interactions - Cu-O and O-O hopping, repulsion at the copper and oxygen and between them - is considered. A general procedure of the low-energy reduction of the primary Hamiltonian to the Hamiltonian of the generalized $t$-$t'$-$J$ model is developed. An important role of the direct O-O hopping is discussed. Parameters of the effective low-energy model (the hopping integral, the band position and the superexchange constant $J$ are calculated. An analysis of the obtained data shows that the experimental value of $J$ fixes the charge transfer energy $Δ=(ε_{p}-ε_{d})$ in a narrow region of energies.

description: Compared to typical multi-sensor systems, monocular 3D object detection has attracted much attention due to its simple configuration. However, there is still a significant gap between LiDAR-based and monocular-based methods. In this paper, we find that the ill-posed nature of monocular imagery can lead to depth ambiguity. Specifically, objects with different depths can appear with the same bounding boxes and similar visual features in the 2D image. Unfortunately, the network cannot accurately distinguish different depths from such non-discriminative visual features, resulting in unstable depth training. To facilitate depth learning, we propose a simple yet effective plug-and-play module, \underline{O}ne \underline{B}ounding Box \underline{M}ultiple \underline{O}bjects (OBMO). Concretely, we add a set of suitable pseudo labels by shifting the 3D bounding box along the viewing frustum. To constrain the pseudo-3D labels to be reasonable, we carefully design two label scoring strategies to represent their quality. In contrast to the original hard depth labels, such soft pseudo labels with quality scores allow the network to learn a reasonable depth range, boosting training stability and thus improving final performance. Extensive experiments on KITTI and Waymo benchmarks show that our method significantly improves state-of-the-art monocular 3D detectors by a significant margin (The improvements under the moderate setting on KITTI validation set are $\mathbf{1.82\sim 10.91\%}$ \textbf{mAP in BEV} and $\mathbf{1.18\sim 9.36\%}$ \textbf{mAP in 3D}).

description: At the heart of the narrative of Dante’s Inferno is a descending hierarchy of categories, referring to human behavior and attitudes, which is largely an expression of the theological and moral (as well as legal, as far as moral judgments are linked to legal judgments) thinking of his time. 
Starting from the application of this system to the framework of human conduct that takes place in the ‘other world’ of the web, this essay aims to reflect on the pure narrative power of the inverted climax of Dante’s Inferno, and above all on its potential applications in the teaching of law and of civic and digital citizenship.

description: We discuss a theoretical approach that employs machine learning potential energy surfaces (ML-PESs) in the nonadiabatic dynamics simulation of polyatomic systems by taking 6-aminopyrimidine as a typical example. The Zhu-Nakamura theory is employed in the surface hopping dynamics, which does not require the calculation of the nonadiabatic coupling vectors. The kernel ridge regression is used in the construction of the adiabatic PESs. In the nonadiabatic dynamics simulation, we use ML-PESs for most geometries and switch back to the electronic structure calculations for a few geometries either near the S1/S0 conical intersections or in the out-of-confidence regions. The dynamics results based on ML-PESs are consistent with those based on CASSCF PESs. The ML-PESs are further used to achieve the highly efficient massive dynamics simulations with a large number of trajectories. This work displays the powerful role of ML methods in the nonadiabatic dynamics simulation of polyatomic systems.
We're Not in Kansai Anymore: Designing for Reverse Culture Shock
Creators: name: Smitha  Prasadh
Publisher: name: Carnegie Mellon University
Year: 2011
Subjects: Design

description: I developed a resource to aid people going through reentry and reverse culture shock after returning from long stays abroad. Based on my experience with the JET Programme, I used North American JET alumni as my case study, but aimed to develop a solution that would be scalable and useful for people in other programs and situations. While JET and other similar programs assist and support participants in the initial journey abroad and during their stay, they tend to not provide much support when the participants return. This is a real issue because culture shock upon returning from an extended trip is stronger and generally unexpected than what’s experienced at the initial departure. Because of the increasing number of people going abroad for extended stays, this highlights a very real need for support, either from the organizing groups or from alumni of those groups and programs. I began my exploratory research with an extensive survey, where I gathered information on people’s situations prior to joining JET, various qualitative and quantative aspects of their time in Japan, and their experiences upon their return. I continued to conduct exploratory research to gather people’s personal experiences, and I worked closely with JET alumni during my generative and evaluative research phases as well. From the beginning, I leaned towards an online solution that would connect JET alumni regardless of distance or location. Though I considered other options, this approach was vindicated by the strong needs for “community” and “shared experiences” voiced by JET alumni throughout all my research. Ultimately I developed a plan for an online platform that enables people to share their experiences through writing and other media, as well as to communicate and connect easily with others. The name of this platform is okaeri, which means both “return” (verb) and “welcome” (greeting) in Japanese. Beyond the site’s structure and function, the key element is the visual-verbal rhetorical strategy throughout the content and layout, which will set an empathetic tone and perpetuate the sense of community that already exists among JET alumni.

As a result of applying Puma super (1 l/ha) against spike weeds and Granstar (15 g/ha) against dicotyledonous weeds, the winter wheat variety Kroshka has a long spike, spikes in the spikes, and the number of grains in the spike and spike from one spike. increase in grain yield, this condition is more effective when the herbicides Puma super (1 l/ha) against weeds with spikes and Granstar (15 g/ha) against dicotyledonous weeds are mixed together and sprayed with a solution, the grain structure is significantly improved.

description: Various approaches to high energy forward scattering in quantum gravity are compared using the eikonal approximation. The massless limit of the eikonal is shown to be equivalent to other approximations for the same process, specifically the semiclassical calculation due to G. 't Hooft and the topological field theory due to H. and E. Verlinde. This comparison clarifies these previous results, as it is seen that the amplitude arises purely from a linearised gravitational interaction. The interpretation of poles in the scattering amplitude is also clarified.

description: Robotic manipulation of slender objects is challenging, especially when the induced deformations are large and nonlinear. Traditionally, learning-based control approaches, such as imitation learning, have been used to address deformable material manipulation. These approaches lack generality and often suffer critical failure from a simple switch of material, geometric, and/or environmental (e.g., friction) properties. This article tackles a fundamental but difficult deformable manipulation task: forming a predefined fold in paper with only a single manipulator. A sim2real framework combining physically-accurate simulation and machine learning is used to train a deep neural network capable of predicting the external forces induced on the manipulated paper given a grasp position. We frame the problem using scaling analysis, resulting in a control framework robust against material and geometric changes. Path planning is then carried out over the generated ``neural force manifold'' to produce robot manipulation trajectories optimized to prevent sliding, with offline trajectory generation finishing 15$\times$ faster than previous physics-based folding methods. The inference speed of the trained model enables the incorporation of real-time visual feedback to achieve closed-loop model-predictive control. Real-world experiments demonstrate that our framework can greatly improve robotic manipulation performance compared to state-of-the-art folding strategies, even when manipulating paper objects of various materials and shapes.

description: To use batteries as large-scale energy storage systems it is necessary to measure and understand their degradation \textit{in-situ} and \textit{in-operando}. As a battery's degradation is often the result of molecular processes inside the electrolyte, a sensing platform which allows to measure the ions with a high spatial resolution is needed. Primary candidates for such a platform are NV-centers in diamonds. We propose to use a single NV-center to deduce the electric field distribution generated by the ions inside the electrolyte through microwave pulse sequences. We show that the electric field can be reconstructed with great accuracy by using a protocol which includes different variations of the Free Induction Decay to obtain the mean electric field components and a modified Hahn-echo pulse sequence to measure the electric field's standard deviation $σ_E$. From a semi-analytical ansatz we find that for a lithium ion battery there is a direct relationship between $σ_E$ and the ionic concentration. Our results show that it is therefore possible to use NV-centers as sensors to measure both the electric field distribution and the local ionic concentration inside electrolytes.
Evolution of the Galactic Halo and Disk

description: Correlations between stellar kinematics and chemical abundances are fossil evidence for evolutionary connections between Galactic structural components. Extensive stellar surveys show that the only tolerably clear distinction between galactic components appears in the distributions of specific angular momentum. Here the stellar metal-poor halo and the metal-rich bulge are indistinguishable from each other, as are the thick disk and the old disk. Each pair is very distinct from the other. This leads to an evolutionary model in which the metal-poor stellar halo evolves into the inner bulge, while the thick disk is a precursor to the thin disk. These evolutionary sequences are distinct. The galaxy is made of two discrete `populations', one of low and one of high angular momentum. Some (minor?) complexity is added to this picture by the debris of late and continuing mergers, which will be especially important in the outer stellar halo.

description: Power-law probability distributions arise often in the social and natural sciences. Statistics have been developed for estimating the exponent parameter as well as gauging goodness-of-fit to a power law. Yet paradoxically, many famous power laws such as the distribution of wealth and earthquake magnitudes have not found good statistical support in data by modern methods. We show that measurement errors such as quantization and noise bias both maximum-likelihood estimators and goodness-of-fit measures. We address this issue using logarithmic binning and the corresponding discrete reference distribution for maximum likelihood estimators and Kolmogorov-Smirnov statistics. Using simulated errors, we validate that binning attenuates bias in parameter estimates and recalibrates goodness of fit to a power law by removing small errors from consideration. These benefits come at modest cost in statistical power, which can be compensated with larger sample sizes. We reanalyse three empirical cases of wealth, earthquake magnitudes and wildfire area and show that binning reverses statistical conclusions and aligns the statistical results with historical and scientific expectations. We explain through these cases how routine errors lead to incorrect conclusions and the necessity for more robust methods.

description: Observations of young open clusters show a bimodal distribution of rotation periods that has been difficult to explain with existing stellar spin-down models. Detailed MHD stellar wind simulations have demonstrated that surface magnetic field morphology has a strong influence on wind-driven angular momentum loss. Observations suggest that faster rotating stars store a larger fraction of their magnetic flux in higher-order multipolar components of the magnetic field. In this work, we present a new model for stellar spin-down that, for the first time, accounts for the stellar surface magnetic field configuration. We show how a magnetic complexity that evolves from complex toward simple configurations as a star spins down can explain the salient features of stellar rotation evolution, including the bimodal distribution of both slow and fast rotators seen in young open clusters.

description: Gross-Oliveira-Kohn density-functional theory (GOK-DFT) is an extension of DFT to excited states where the basic variable is the ensemble density, i.e. the weighted sum of ground- and excited-state densities. The ensemble energy (i.e. the weighted sum of ground- and excited-state energies) can be obtained variationally as a functional of the ensemble density. Like in DFT, the key ingredient to model in GOK-DFT is the exchange-correlation functional. Developing density-functional approximations (DFAs) for ensembles is a complicated task as both density and weight dependencies should in principle be reproduced. In a recent paper [Phys. Rev. B 95, 035120 (2017)], the authors applied exact GOK-DFT to the simple but nontrivial Hubbard dimer in order to investigate (numerically) the importance of weight dependence in the calculation of excitation energies. In this work, we derive analytical DFAs for various density and correlation regimes by means of a Legendre-Fenchel transform formalism. Both functional and density driven errors are evaluated for each DFA. Interestingly, when the ensemble exact-exchange-only functional is used, these errors can be large, in particular if the dimer is symmetric, but they cancel each other so that the excitation energies obtained by linear interpolation are always accurate, even in the strongly correlated regime.

description: This study compared use of byproduct-based concentrates and a control feed based on cereal grains and soybean meal in dairy cow diets and evaluated effects on the environment and feed costs. To achieve a nutrient-dense feed ration to dairy cows byproducts are commonly combined with cereal grains and protein-rich feeds such as soybean meal. The present analysis was based on experimental data for high-yielding dairy cows showing that feeding concentrate based on byproducts gives similar milk yield as feeding concentrate based on cereal grains and soybean meal. Evaluation of the different concentrates using life cycle assessment showed that using byproducts required less cropland (−35%), reduced carbon footprint (−20%) and lowered eutrophication potential (−20%) compared with the control. Energy use was higher (+30%), due to the need for drying wet byproducts. Feed costs per kg energy-corrected milk did not differ between the feeds, which is beneficial from a sustainability perspective.

description: We prove that the kernel of the natural action of the modular group on the center of the Drinfel'd double of a semisimple Hopf algebra is a congruence subgroup. To do this, we introduce a class of generalized Frobenius-Schur indicators and endow it with an action of the modular group that is compatible with the original one.

description: The present study investigated the impact of Iranian English as Foreign Language (EFL) learners’ collaborative writing through Google Docs on their classroom engagement. To attain the purpose of the study, 50 Iranian EFL learners were selected. Two instruments were used to gather the required data; classroom engagement questionnaire, and a semi-structured interview. At the first session of the class, the first researcher/teacher asked the participants of both groups to fill in the engagement scale as the pre-test. The experimental group received a 60-minute training session to acquaint them with collaborative writing and engage in pre-task modelling of collaboration. During the study intervention, the experimental group received online collaborative writing using Google Docs while the control group underwent conventional methods of teaching. At the end of the treatment, both groups took a post-test. To analyse the obtained data a set of descriptive statistics and independent samples t-test were used. The results revealed that collaborative writing through Google Docs has a significant effect on the participants’ classroom engagement since the participants of the experimental group outperformed the participants of the control group in the post-test. The obtained data from the interview were reported qualitatively. The results revealed participants’ positive views regarding using Google Docs and it provided their ideas regarding its use in future courses. The findings have implications for EFL teachers and learners.

description: We consider the possibility that instabilities of the Abrikosov-Suhl resonance lead to new fixed point behavior of the Kondo effect in a lattice environment. In one scenario, a pairing component to the resonant scattering develops in the Kondo lattice, leading to an odd frequency superconductor. We discuss experiments that can discriminate between this picture and d-wave pairing, and its relationship to the non Fermi liquid fixed point of the overscreened Kondo model.

Wearasound : Beyond Visual Centric Interaction - Designing Sound for Enhancing Visual Contents
Creators: name: Han, Gilbert Seungheon
Publisher: name: Carnegie Mellon University
Year: 2014
Subjects: Design

description: The appropriate use of sounds has the potential to add a great deal to convey information in interactive commodities. Sound is a largely unexplored medium as a design element in interaction design community, even though it plays an integral role in our everyday encounters with the world, on that complementary to vision. However, information and data are predominantly represented in visual form. I argue that sound should be used in designing interactive commodities as a way to improve and enhance visual experience of the artifact. Such strategy leads to build sound design guideline and framework to help designers who are not familiar with sound design. The first half of this project focuses on revealing potentials of sounds, where sound can be used and sound design methodological point of view. These ideas are instantiated in the Wearasound, a wearable auditory device for conveying contextual information in real time without distraction. Wearasound is designed to be used while the user is moving. A range of auditory information provide peripheral awareness and indirect interaction. Delivering information is adaptive and context sensitive; appropriate information is presented as more or less obtrusive based on user’s situated context. Preliminary user evaluation suggest that audio is an appropriate medium for conveying certain domains of information (particularly for content that is intrinsically voice/audio) in specific usage context (when the user’s hands or eyes are busy).

description: Deviations from the predictions of general relativity due to energy-momentum squared gravity (EMSG) are expected to become pronounced in the high density cores of neutron stars. We derive the hydrostatic equilibrium equations in EMSG and solve them numerically to obtain the neutron star mass-radius relations for four different realistic equations of state. We use the existing observational measurements of the masses and radii of neutron stars to constrain the free parameter, $α,$ that characterizes the coupling between matter and spacetime in EMSG. We show that $-10^{-38}\,\mathrm{cm^{3}/erg}

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Local deformation of atomically thin van der Waals materials provides a powerful approach to create site-controlled chip-compatible single-photon emitters (SPEs). However, the microscopic mechanisms underlying the formation of such strain-induced SPEs are still not fully clear, which hinders further efforts in their deterministic integration with nanophotonic structures for developing practical on-chip sources of quantum light. Here we investigate SPEs with single-photon purity up to 98% created in monolayer WSe$_2$ via nanoindentation. Using photoluminescence imaging in combination with atomic force microscopy, we locate single-photon emitting sites on a deep sub-wavelength spatial scale and reconstruct the details of the surrounding local strain potential. The obtained results suggest that the origin of the observed single-photon emission is likely related to strain-induced spectral shift of dark excitonic states and their hybridization with localized states of individual defects.
