description: Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined a vertical metallicity gradient over a large volume of the Milky Way's disk, and examined how this gradient varies for different [a/Fe] subsamples. This sample contains over 40,000 stars with low-resolution spectroscopy over 144 lines of sight. We employ the SEGUE Stellar Parameter Pipeline (SSPP) to obtain estimates of effective temperature, surface gravity, [Fe/H], and [a/Fe] for each star and extract multiple volume-complete subsamples of approximately 1000 stars each. Based on the survey's consistent target-selection algorithm, we adjust each subsample to determine an unbiased picture of the disk in [Fe/H] and [a/Fe]; consequently, each individual star represents the properties of many. The SEGUE sample allows us to constrain the vertical metallicity gradient for a large number of stars over a significant volume of the disk, between ~0.3 and 1.6 kpc from the Galactic plane, and examine the in situ structure, in contrast to previous analyses which are more limited in scope. This work does not pre-suppose a disk structure, whether composed of a single complex population or a distinct thin and thick disk component. The metallicity gradient is -0.243 +0.039 -0.053 dex/kpc for the sample as a whole, which we compare to various literature results. Each [a/Fe] subsample dominates at a different range of heights above the plane of the Galaxy, which is exhibited in the gradient found in the sample as a whole. Stars over a limited range in [a/Fe] show little change in median [Fe/H] with height. If we associate [a/Fe] with age, our consistent vertical metallicity gradients with [a/Fe] suggest that stars formed in different epochs exhibit comparable vertical structure, implying similar star-formation processes and evolution.

a-synuclein
Parkinson's Disease

description: Alpha-synuclein (α-syn) and LRRK2 are two proteins that play crucial roles in Parkinson’s disease (PD) and recent data suggest the existence of an interplay between these two proteins (1,2).

We hypothesized that the level of kinase activity of LRRK2 may modulate α-syn toxicity.

To address this, using adeno-associated virus (AAV), we overexpressed in the rat substantia nigra pars compacta (SNc), both mutated (A53T) α-syn and 3 different LRRK2 constructs: the C-terminal part of LRRK2 (ΔLRRK2), a ΔLRRK2 with the G2019S pathogenic mutation, and the dead kinase double mutant form of LRRK2 (G2019S/A1994E). First we established that AAV-ΔLRRK2G2019S alone or mixed with AAV-GFP was not toxic at different time points up to 25 weeks post-infection (p.i.) Then we examined the effects of the ΔLRRK2 forms at two different titers of AAV-α-synA53T: low (leading to ~30% loss of DA neurons at 15 weeks) or high (leading to ~15% loss of DA neurons within 8 weeks).

Our results showed that injection of a mixture of AAV-ΔLRRK2G2019S and low titer AAV-α-synA53T produced significantly more degeneration than AAV- α-synA53T alone or AAV- α-synA53T mixed with AAV-GFP.

Moreover, the mild toxicity of low titer AAV-α-synA53T seen at 6 weeks p.i. was reduced when mixed with AAV-ΔLRRK2G2019S/A1994E.

In a set up where AAV- α-synA53T was injected at higher (5x1010 vg/site) titer , AAV-ΔLRRK2G2019S, ΔLRRK2G2019S/A1994E and AAV-GFP had no impact on the resulting neuronal loss in SNpc.

These results suggest that, when neurodegeneration of DA neurons results from relatively low levels of α-synA53T overexpression, increasing the levels of the active C-terminal domain of LRRK2G2019S can be sufficient to exacerbate α-synA53T toxicity.

Collaborative ranking-based recommender systems

Year: 2018

description: Recommender systems are by far one of the most successful applications of big data and machine learning. The goal of recommender systems is to find what is likely to be of interest, thus enabling personalization and tailored services.  Among all the recommendation algorithms, collaborative filtering is the most common technique. In this thesis, we present our research results in the field of ranking-based collaborative filtering. We view the task of recommendation as providing a personalized ranked list of items for each user and thus formulate it as a ranking problem. In order to generate accurate recommended lists, we look into the technique of combining learning-to-rank with conventional collaborative filtering methods for solving the recommendation task and comprehensively discuss the challenges and advantages of this approach. Particularly, we propose an improved pairwise ranking model and a multi-objective ranking framework to address the issues which occur during the  combination of learning-to-rank and collaborative filtering. In addition, we propose a new ordinal approach to modeling the ordinal nature of user preference scores, which demonstrates distinct superiority compared to the numerical and (nominal) categorical views of user ratings.

description: Magneto-Optical Traps have been used for several decades. Among fundamental mechanisms occuring in such traps, the magnitude of the multiple scattering is still unclear. Indeed, many experimental situations cannot be modeled easily, different models predict different values of the re-absortion cross section, and no simple experimental measurement of this cross section are available. We propose in this paper a simple measurement of this cross section through the size and the shape of the cloud of cold atoms. We apply this method to traps with a configuration where theoretical values are available, and show that the measured values are compatible with some models. We also apply the method to configurations where models are not relevant, and show that the re-absorption is sometimes much larger than the usually assumed value.
Ion dynamics of ethylammonium nitrate by means of Quasielastic neutron scattering

Publisher: name: No Publisher Supplied
Year: 2018

description: Ionic Liquids (ILs) are salts with a melting point below 100 ˚C. In recent years, ILs have garnered popular interest in academia and industry due to their unique properties and heterogeneous solvent nanostructure. In this Thesis, the solvent dynamics of one of the oldest, and most widely used ILs, ethylammonium nitrate (EAN) is examined using Quasi-Elastic Neutron Scattering (QENS) with H/D isotopic substitution. The data is fitted using analytical diffusions models and Bayesian statistics. The results show that long range cation motion in ILs is consistent with unrestricted (Fickian) translational diffusion. The measured cation diffusion coefficient of 3.96 × 10-11 m2/s (298 K) is comparable to other self-assembled systems and two orders of magnitude slower than for molecular liquids (e.g. water @ 292 K, D = 2.36 × 10-9 m2/s). The activation energy for all diffusion processes was independent of IL solvent within QENS instrument resolution and shown to follow Arrhenius dependence with temperature. These results demonstrate that long-range ion mobility in ILs is likely linked to revelations of long-range solvent nanostructure.

description: This thesis explores the causes and consequences of social and civil conflict, within the field of political economy. It consists of three self-contained empirical studies that advance the current body of knowledge on the relationship between natural resource abundance, conflict, and the impact of violence. While the focus of the existing political economy literature has mainly been on armed civil conflict and war, this thesis focus on social conflict around environmental degradation and communal land rights. It provides new insights on why socio-environmental conflicts turn violent and how civil society can hold powerful multinational corporations accountable for human rights violations.

description: Dark matter halos are built from accretion and merging. During merging some of the dark matter particles may be ejected with velocities higher than the escape velocity. We use both N-body simulations and single-particle smooth-field simulations to demonstrate that rapid changes to the mean field potential are responsible for such ejection, and in particular that dynamical friction plays no significant role in it. Studying a range of minor mergers, we find that typically between 5-15% of the particles from the smaller of the two merging structures are ejected. We also find that the ejected particles originate essentially from the small halo, and more specifically are particles in the small halo which pass later through the region in which the merging occurs.

Modeling, Simulating and Quantification of Optical Images of Ultrasound Contrast Bubbles
Creators: name: Habtamu Abraham
Publisher: name: Zenodo
Year: 2017

description: Microbubble based ultrasound contrast agents are being used in clinical settings to

enhance backscattered ultrasound signal from blood pool during perfusion and blood flow

measurements. Often individual bubbles are characterized optically by recording their

vibrations with a fast framing camera and direct quantitative information on their dynamic

behavior can be derived. Nonetheless, when a three-dimensional object, stack of infinitely thin

two-dimensional layers, is imaged through a microscope, the image formed onto the charge

coupled device element consists of contributions from all layers. If a bubble is larger than the

depth of focus, the part of the bubble above the focal plane influences the image formation

and therefore the bubble size measured. Thus, this thesis presents a methodology to compute

two-dimensional image formation from three-dimensional objects, hollow spheres and find

under which circumstances the optical image formation leads to a significant deviation in

measurement of the actual size. Two-dimension image formations of the three-dimensional

object was computed by convolving the slices of an artificial object, hollow spheres with the

respective weighted point spread function and summing all convolved slices. Finally, image

processing was applied the optical image formed to quantify the object size and a systematic

error was observed for objects in focus with radius 1:65mm. Also it was concluded that

even though a three-dimensional object is in focus, there is discrepancy of up to 0.66% in size

measurement.

description: Johne's disease or Mycobacterium avium subspecies paratuberculosis (MAP) causes chronic granulomatous enteritis with decrease in production resulting huge economic losses with high negative impact on the livestock industry. Diagnosis of MAP is difficult due to lack of characteristics clinical signs, prolong incubation period in cultivation of MAP, and non-specific results in diagnostic tests. To the best of our knowledge there is no report on faecal culture and molecular detection of MAP in dairy cattle of Nepal. The main objective of this research was to access the herd level prevalence of Johne’s disease in the representative dairy farms of Chitwan district with the use of modern techniques as faecal polymerase chain reaction (fPCR) to know the MAP distribution in dairy cattle. A total of 265 individual dairy cattle faeces sample were collected during February 2017 to January 2018 from dairy farms of three different geographical location of Chitwan district, Nepal. Faeces were decontaminated and subjected for faecal culture as well as fPCR to have molecular detection of MAP. Findings revealed that bio-load of MAP in dairy cattle were 13.57% by faecal culture, and 16.59% by fPCR detection method. The overall prevalence of MAP in dairy cattle was detected as 16.59 % by fPCR. Likewise, IS900 PCR assay proved to be a more sensitive and reliable test than faecal culture for the detection of MAP in faecal sample of clinically suspected dairy cattle as the PCR assay was able to detect significantly (p < 0.01) more positive cases than faecal culture. Findings of this study suggests that IS900-PCR-based detection of MAP could be used as a potential diagnostic tool for rapid and effective Johne’s disease (JD) surveillance as compared with faecal culture detection method due to its advantage for JD control programs by reducing the time of definitive diagnosis from several months to a few days. This is the first molecular level of diagnostic research performed and reporting of MAP in dairy cattle of Nepal. These results will be useful in designing suitable disease control strategy for livestock industry.

description: In this paper, we study radiative decays of X_b, the counterpart of the famous X(3872) in the bottomonium-sector as a candidate for meson-meson molecule, into the γΥ(nS) (n=1, 2, 3). Since it is likely that the X_b is below the B\bar B^* threshold and the mass difference between the neutral and charged bottom meson is small compared to the binding energy of the X_b, the isospin violating decay mode X_b\to Υ(nS)π^+π^- would be greatly suppressed. This will promote the importance of the radiative decays. We use the effective Lagrangian based on the heavy quark symmetry to explore the rescattering mechanism and calculate the partial widths. Our results show that the partial widths into γΥ(nS) are about 1 keV, and thus the branching fractions may be sizeable, considering the fact the total width may also be smaller than a few MeV like the X(3872). These radiative decay modes are of great importance in the experimental search for the X_b particularly at hadron collider. An observation of the X_b will provide a deeper insight into the exotic hadron spectroscopy and is helpful to unravel the nature of the states connected by the heavy quark symmetry.

A search for light pair-produced particles that each decay into at least four quarks
Creators: name: Hughes, Elliot John
Publisher: name: No Publisher Supplied

description: A search for pair-produced particles with masses above 100 GeV that each decay into at least four quarks is presented. The search focuses on a signal model consisting of a squark that decays into four quarks through an intermediate Higgsino with a hadronic R-parity-violating coupling. Data from proton-proton collisions with 13 TeV center-of-mass energy, collected by the Compact Muon Solenoid experiment at the Large Hadron Collider during 2015 and 2016, are analyzed for resonances in the average mass spectrum of pairs of large jets with high transverse momentum, similar mass, and substructure consistent with four partons. A novel data-driven technique is used to estimate the dominant quantum-chromodynamic multijet background events. The significant top-quark decay background events are accounted for by simulation. No statistically significant excess of observed events over expected events in the data is found. The pair production of squarks with masses between 0.10 and 0.72 TeV and gluinos with masses between 0.10 and 1.41 TeV are excluded at 95% confidence level.

description: Abstract:
Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift are under way along with the development of computer programs for diversity indices of the various organisms. Twenty-eight species of bivalve mussels and representatives of six genera of snails have been collected including the Asiatic clam Corbicula mülleri. Among the vertebrates, 60 species of fishes have been collected and identified along with 22 amphibians and 21 reptiles. Nearly 150 species of birds have been identified in the area.
An economic study of Spencer County revealed that there has been a decrease in the human population along with a general decline in the overall economic picture of the county as indicated by a retarded rate of growth in annual per capita income and a decline in total retail sales within the county over the past decade. The highway system in the county consists of largely Class 4, 5, and 6 roads which, because of the topography, are generally narrow, crooked, and hilly. However, Spencer County is almost completely encircled by interstate highways within ten miles of its borders.

Informed Guided Rapidly-Exploring Random Trees*-Connect for Path Planning of Walking Robots

description: In this paper, we deal with the problem of full-body path planning for walking robots. The state of walking robots is defined in multi-dimensional space. Path planning requires defining the path of the feet and the robot's body. Moreover, the planner should check multiple constraints like static stability, self-collisions, collisions with the terrain, and the legs' workspace. As a result, checking the feasibility of the potential path is time-consuming and influences the performance of a planning method. In this paper, we verify the feasibility of sampling-based planners in the path planning task of walking robots. We identify the strengths and weaknesses of the existing planners. Finally, we propose a new planning method that improves the performance of path planning of legged robots.

description: Nowadays, embedded systems are provided with cache memories that are large enough to influence in both performance and energy consumption as never occurred before in this kind of systems. In addition, the cache memory system has been identified as a component that improves those metrics by adapting its configuration according to the memory access patterns of the applications being run. However, given that cache memories have many parameters which may be set to a high number of different values, designers face to a wide and time-consuming exploration space. In this paper we propose an optimization framework based on Grammatical Evolution (GE) which is able to efficiently find the best cache configurations for a given set of benchmark applications. This metaheuristic allows an important reduction of the optimization runtime obtaining good results in a low number of generations. Besides, this reduction is also increased due to the efficient storage of evaluated caches. Moreover, we selected GE because the plasticity of the grammar eases the creation of phenotypes that form the call to the cache simulator required for the evaluation of the different configurations. Experimental results for the Mediabench suite show that our proposal is able to find cache configurations that obtain an average improvement of $62\%$ versus a real world baseline configuration.

description: Open-Source Software results from contributions from people with all skill levels. Contributions have distinct and fundamental roles in software development. Recent studies investigate developers’ contributions (human factors) and their influence on software quality. Human aspects play an essential role in software quality. OSS projects are still produced in high quality, yet designer problems can occur. These problems are called test smells. Test smells are bad implementations or problems in the design of test code. One of the problems caused by test smells is the comprehension of test suites. Some authors have carried out studies on the developer’s perception of test smells, but the studies did not focus on the human aspects, only on how developers look at test smells. There are several studies on the quality of the test code in the literature, but there is limited empirical evidence on studies investigating the relationship between human aspects and the quality of the test code from the perspective of test smells. The goal is to conduct a family of empirical studies to investigate the relationship between human aspects and test code quality from the perspective of test smells. We will approach two methodologies based on data mining and survey/Interview study. As a result, the approach will build a guideline containing best testing practices for preventing test smells in test code

description: Motivated by the recent IceCube result, we study high energy cosmic-ray neutrino flux from the decay of a long-lived particle. Because neutrinos are so transparent, high energy neutrinos produced in the past may also contribute to the present neutrino flux. We point out that the PeV neutrino events observed by IceCube may originate in the decay of a particle much heavier than PeV if its lifetime is shorter than the present cosmic time. It is shown that the mass of the particle responsible for the IceCube event can be as large as $\sim 10^{10}\ {\rm GeV}$. We also discuss several possibilities to acquire information about the lifetime of the long-lived particle.

B 84, 201308(R) (2011), an isolated Majorana state bound to one edge of a long enough Kitaev chain in the topological phase and connected to a quantum dot, results in a robust transmittance of $1/2$ at zero-bias. In this work, we show that the removal of such a hallmark can be achieved by using a metallic surface hosting two adatoms in a scenario where there is a lack of symmetry in the Fano effect, which is feasible by coupling the Kitaev chain to one of these adatoms. Thus in order to detect this feature experimentally, one should apply the following two-stage procedure: (i) first, attached to the adatoms, one has to lock AFM tips in opposite gate voltages (symmetric detuning of the levels) and measure by an STM tip, the zero-bias conductance; (ii) thereafter, the measurement of the conductance is repeated with the gates swapped. For the absolute value of the detuning away from the Fermi energy and in the case of strong coupling tip-host, this approach reveals in the transmittance, a persistent dip placed at zero-bias and immune to the aforementioned permutation, but characterized by an amplitude that fluctuates slightly around $1/2$. However, in the case of a tip acting as a probe, the adatom decoupled from the Kitaev chain becomes completely inert and no fluctuation is observed. Therefore, the STM tip must be considered in the same footing as the "host+adatoms" system. As a result, we have found that despite the small difference between these two Majorana dips, the zero-bias transmittance as a function of the symmetric detuning yields two distinct behaviors, in which one of them is unpredictable by the standard Fano's theory. Therefore, to access such a non trivial pattern of Fano interference, the hypothesis of the STM tip acting as a probe should be discarded.

description: Observations revealed the presence of multiple stellar populations in globular clusters (GCs) that exhibit wide abundance variations and multiple sequences in Hertzsprung-Russell (HR) diagram. We present a scenario for the formation of multiple stellar populations in GCs. In this scenario, initial GCs are single-generation clusters, and our model predicts that the abundance anomalous stars observed in GCs are the merged stars and the accretor stars produced by binary interactions, which are rapidly rotating stars at the moment of their formation and are more massive than normal single stars in the same evolutionary stage. We find that due to their own evolution, these rapidly rotating stars have different surface abundances, effective temperatures and luminosities from normal single stars in the same evolutionary stage. The stellar population with binaries can reproduce two important observational evidences of multiple stellar populations, the Na-O anticorrelation and the multiple sequences in HR diagram. This suggests that binary interactions may be a possible scenario for the formation of multiple stellar populations in GCs.

description: Consistency and predictability of brain functionalities depend on reproducible activity of a single neuron. We identify a reproducible non-chaotic neuronal phase where deviations between concave response latency profiles of a single neuron do not increase with the number of stimulations. A chaotic neuronal phase emerges at a transition to convex latency profiles which diverge exponentially, indicating irreproducible response timings. Our findings are supported by a quantitative mathematical framework and found robust to periodic and random stimulation patterns. In addition, these results put a bound on the neuronal temporal resolution which can be enhanced below a millisecond using neuronal chains.

description: Motion planning framed as optimisation in structured latent spaces has recently emerged as competitive with traditional methods in terms of planning success while significantly outperforming them in terms of computational speed. However, the real-world applicability of recent work in this domain remains limited by the need to express obstacle information directly in state-space, involving simple geometric primitives. In this work we address this challenge by leveraging learned scene embeddings together with a generative model of the robot manipulator to drive the optimisation process. In addition, we introduce an approach for efficient collision checking which directly regularises the optimisation undertaken for planning. Using simulated as well as real-world experiments, we demonstrate that our approach, AMP-LS, is able to successfully plan in novel, complex scenes while outperforming traditional planning baselines in terms of computation speed by an order of magnitude. We show that the resulting system is fast enough to enable closed-loop planning in real-world dynamic scenes.

description: Idioms and proverbs often present a high level of difficulty in translation. The paper addresses the wide range of possible strategies to face this challenge, comparing six translations of the “Nibelungenlied” in three languages: German, English, and Italian. The analysis will further consider the complex issues related to the so-called “intertemporal translation”.

description: AI technologies continue to advance from digital assistants to assisted decision-making. However, designing AI remains a challenge given its unknown outcomes and uses. One way to expand AI design is by centering stakeholders in the design process. We conduct co-design sessions with gig workers to explore the design of gig worker-centered tools as informed by their driving patterns, decisions, and personal contexts. Using workers' own data as well as city-level data, we create probes -- interactive data visuals -- that participants explore to surface the well-being and positionalities that shape their work strategies. We describe participant insights and corresponding AI design considerations surfaced from data probes about: 1) workers' well-being trade-offs and positionality constraints, 2) factors that impact well-being beyond those in the data probes, and 3) instances of unfair algorithmic management. We discuss the implications for designing data probes and using them to elevate worker-centered AI design as well as for worker advocacy.

description: Contrary to the intense debate about brain oxygen dynamics and its uncoupling in mammals, very little is known in birds. In zebra finches, picosecond optical tomography (POT) with a white laser and a streak camera can measure in vivo oxy-hemoglobin (HbO2) and deoxy-hemoglobin (Hb) concentration changes following physiological stimulation (familiar calls and songs). POT demonstrated sufficient sub-micromolar sensitivity to resolve the fast changes in hippocampus and auditory forebrain areas with 250 μm resolution. The time-course is composed of (i) an early 2s-long event with a significant decrease in Hb and HbO2, respectively -0.7 μMoles/L and -0.9 μMoles/L (ii) a subsequent increase in blood oxygen availability with a plateau of HbO2 (+0.3 μMoles/L) and (iii) pronounced vasodilatation events immediately following the end of the stimulus. One of the findings of our work is the direct link between the blood oxygen level-dependent (BOLD) signals previously published in birds and our results. Furthermore, the early vasoconstriction event and post-stimulus ringing seem to be more pronounced in birds than in mammals. These results in bird, a tachymetabolic vertebrate with a long lifespan, can potentially yield new insights for example in brain aging.

description: Gianfranco Contini (1986) argued that the immediate purpose of philology is to arouse the perception of cultural distance between the observer (the philologist) and the object of investigation (the text). While aknowledging that the only suitable translation for the strophic structure of the “Nibelungenlied” is prose rendering, a balance between the semantic precision in translation and the attempt to reproduce the stylistic features of the original is desirable to avoid trivialising the peculiarities of the poem’s style. This argument is supported by the analysis of a series of technicisms (e.g., nouns, as voget, mœre, etc.), idiomatic expressions (e.g., the formulaic usage of adjectives as wætlîch) and recursive formulae (e.g., lîp : wîp in the “Abvers”), whose translation is particularly challenging.

description: We present a detailed, 3D hydrodynamics study of the neutrino-driven winds that emerge from the remnant of a NS merger. Our simulations are performed with the Newtonian, Eulerian code FISH, augmented by a detailed, spectral neutrino leakage scheme that accounts for heating due to neutrino absorption in optically thin conditions. Consistent with the 2D study of Dessart et al. (2009), we find that a strong baryonic wind is blown out along the original binary rotation axis within $100$ ms after the merger. We compute a lower limit on the expelled mass of $3.5 \times 10^{-3} M_{\odot}$, large enough to be relevant for heavy element nucleosynthesis. The physical properties vary significantly between different wind regions. For example, due to stronger neutrino irradiation, the polar regions show substantially larger $Y_e$ than those at lower latitudes. This has its bearings on the nucleosynthesis: the polar ejecta produce interesting r-process contributions from $A\sim 80$ to about 130, while the more neutron-rich, lower-latitude parts produce also elements up to the third r-process peak near $A\sim 195$. We also calculate the properties of electromagnetic transients that are powered by the radioactivity in the wind, in addition to the macronova transient that stems from the dynamic ejecta. The high-latitude (polar) regions produce UV/optical transients reaching luminosities up to $10^{41} {\rm erg \, s^{-1}}$, which peak around 1 day in optical and 0.3 days in bolometric luminosity. The lower-latitude regions, due to their contamination with high-opacity heavy elements, produce dimmer and more red signals, peaking after $\sim 2$ days in optical and infrared. Our numerical experiments indicate that it will be difficult to infer the collapse time-scale of the HMNS to a BH based on the wind electromagnetic transient, at least for collapse time-scales larger than the wind production time-scale.
