description: Receptive syringe sharing (RSS) among people who inject drugs (PWID) is a risk factor for hepatitis C virus and HIV infections. PWID with borderline personality disorder (BPD) have increased risk of RSS, but it remains unclear what drives this association. This study used ecological momentary assessment (EMA) to study characteristics associated with BPD, and RSS among PWID. We recruited PWID, ages 18–35, through two Community Outreach Intervention Projects syringe service program sites in Chicago, Illinois. After a baseline interview, participants used a mobile phone app to respond to momentary surveys on mood, substance use, and injection risk behavior for two weeks. For each momentary assessment, ratings on negative mood descriptors were combined to create measures of total negative affect (NA), and NA components of dejection, shame, anger, irritability, and worry. RSS was defined by participant responses indicating that they had used a syringe that someone else had used. We estimated mixed effects logistic models, regressing RSS on baseline affect-related impulsivity, lagged momentary NA, and the interaction term. Out of 163 participants who completed at least two EMA assessments, 152 (93%) reported at least one injection event and had valid pre-injection mood assessments required to be included in the analysis. We found that affect-related impulsivity, combined with worried mood in the hours preceding the injection episode, predicted increased risk of RSS. PWID having difficulties with emotion regulation may be at increased risk of RSS during periods of anxiety or tension. (PsycInfo Database Record (c) 2020 APA, all rights reserved)

description: Nowadays cloud computing adoption as a form of hosted application and services is widespread due to decreasing costs of hardware, software, and maintenance. Cloud enables access to a shared pool of virtual resources hosted in large energy-hungry data centers for diverse information and communication services with dynamic workloads. The huge energy consumption of cloud data centers results in high electricity bills as well as emission of a large amount of carbon dioxide gas. Needless to say, efficient resource management in cloud environments has become one of the most important priorities of cloud providers and consequently has increased the interest of researchers to propose novel energy saving solutions. This chapter presents a scientific and taxonomic survey of recent energy efficient cloud resource management' solutions in cloud environments. The main objective of this study is to propose a novel complete taxonomy for energy-efficient cloud resource management solutions, review recent research advancements in this area, classify the existing techniques based on our proposed taxonomy, and open up new research directions. Besides, it reviews and surveys the literature in the range of 2015 through 2021 in the subject of energy-efficient cloud resource management techniques and maps them to its proposed taxonomy, which unveils novel research directions and facilitates the conduction of future researches.

Polyphonic Sound Event Detection with Weak Labeling
Creators: name: Wang, Yun
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Artificial Intelligence and Image Processing not elsewhere classified

description:  Sound event detection (SED) is the task of detecting the type as well as the onset and offset times of sound events in audio streams. It is useful for multimedia retrieval, surveillance, etc. SED is difficult because sound events exhibit diverse temporal and spectral characteristics, and because they can overlap with each other. 
Ideally, SED systems should be trained with strong labeling, which provides the type, onset time and offset time of each sound event occurrence. However, such labeling is formidably tedious to produce by hand. Current research on SED often uses weak labeling. This thesis deals with two types of weak labeling: presence/absence labeling, which only states which types of events are present in each recording without any temporal information, and sequential labeling, which only provides the order of sound events, but without timestamps. Even if the training data is weakly labeled, we still want our SED systems to localize the sound events in time. 
SED with presence/absence labeling is usually treated as a multiple instance learning (MIL) problem, which requires a pooling function. In this thesis, we compare six pooling functions both theoretically and empirically, and establish the linear softmax pooling function as the optimal. Using this function, we build a state-of-the-art network that not only recognizes the types of sound events, but also localizes them temporally. 
SED with sequential labeling has not received much attention. In this thesis, we propose a novel connectionist temporal localization (CTL) framework, which successfully makes use of the extra temporal information in sequential labeling compared with presence/absence labeling. 
Transfer learning is a popular technique to deal with insufficient training data. In this thesis we extract features from two neural networks trained for out-of-domain tasks, and show that these features can improve the SED performance when the training corpus is small.

description: The chameleon model is a modified gravity theory that introduces an additional scalar field that couples to matter through a conformal coupling. This `chameleon field' possesses a screening mechanism through a nonlinear self-interaction term which allows the field to affect cosmological observables in diffuse environments whilst still being consistent with current local experimental constraints. Due to the self-interaction term the equations of motion of the field are nonlinear and therefore difficult to solve analytically. The analytic solutions that do exist in the literature are either approximate solutions and or only apply to highly symmetric systems. In this work we introduce the software package SELCIE (https://github.com/C-Briddon/SELCIE.git). This package equips the user with tools to construct an arbitrary system of mass distributions and then to calculate the corresponding solution to the chameleon field equation. It accomplishes this by using the finite element method and either the Picard or Newton nonlinear solving methods. We compared the results produced by SELCIE with analytic results from the literature including discrete and continuous density distributions. We found strong (sub-percentage) agreement between the solutions calculated by SELCIE and the analytic solutions.

description: Conventional methodologies to link damage evolution with the activation of deformation mechanisms typically require destructive testing and post-mortem analysis. More recently, mechanical testing combined with acoustic emission analysis has provided a method to fingerprint multiple active deformation mechanisms. However, correlating different acoustic emission signals with active deformation sources remains a non-trivial task due to the simultaneous activation of sources during mechanical testing. Here, we demonstrate a multiscale indentation-based technique to isolate dislocation and martensitic transformation sources in the acoustic emission data of a complex alloy. For this purpose, the acoustic emission signals from macro- and microindentation experiments are compared with microscopy and crystallographic analysis of deformed microstructures. A key feature of this method is the selective activation of the martensitic transformation during microindentation, which enables separate fingerprinting of this deformation mechanism. An unsupervised k mean clustering methodology is leveraged to classify acoustic emission waveforms into clusters, which facilitates the detection of shared deformation mechanisms across different tests. The results of this study provide a rapid non-destructive tool to correlate acoustic emission sources with deformation mechanisms in complex alloys.

description: The formation of nuclear star clusters (NSCs) remains an open question. In this work, we use spatially resolved HST/STIS spectroscopic observations of three nearby NSCs (hosted by NGC 5102, NGC 5206, and NGC 205) to constrain their formation histories by exploring radial variations of the stellar populations within each cluster. Utilizing full-spectrum fitting, we find substantial age and metallicity gradients within the central 0."9 (16~pc) of the NSC in NGC 5102 where populations near the center are young/metal-rich (age ~400~Myr and [M/H] ~-0.4) and become older/metal-poor at larger radii (mean age ~1~Gyr and mean [M/H] ~-1.6 in the radial range [0."3, 0."9]). This behavior suggests that the young/metal-rich population at the center was formed from a period of in situ formation, while the older/metal-poor populations were likely formed by inspiraled globular clusters. The two broad populations observed in the NGC 5102 NSC (young/metal-rich and old/metal-poor) appear to be linked to the transition between the two morphological components of the NSC derived from the surface-brightness profile in Nguyen et al. (2018)(arXiv:1711.04314). The radial ranges explored in NGC 5206 and NGC 205 were much smaller due to poor data quality; in NGC 5206 we find a similar metallicity gradient to NGC 5102 (but with much lower significance), while the data for NGC 205 is too poor to reach any conclusions. Overall, this data highlights the links between the morphological and stellar population complexity of NSCs and their formation mechanisms.

description: We propose a spin valve that is based on van der Waals antiferromagnetism and fully electrically controlled. The device is composed of two antiferromagnetic terminals that allow for vertical bias control and a linked central scattering potential region. The magnetoresistance varies significantly when the bias orientations in two terminals are switched from parallel to antiparallel because this switch induces a mismatch of the bands for the same spin projection in different parts of the system. It is shown from density functional calculations that bilayer graphene encapsulated by two atomic layers of Cr$_2$Ge$_2$Te$_6$ provides a material platform to realize the antiferromagnetism, which is robust against the required vertical electric fields.

description: Superconductivity with transition temperature Tc above 40 K was observed in protonated FeSe (Hy-FeSe) previously with the ionic liquid of EMIM-BF4 used in the electrochemical process. However, the real superconducting phase is not clear until now, and detailed structural, magnetization and electrical transport measurements are lacking. By using similar protonating technique on FeSe single crystals, we obtained superconducting samples with Tc above 40 K. We show that the obtained superconducting phase is not Hy-FeSe but actually an organic-ion (C6H11N2+ referred to as EMIM+)-intercalated phase (EMIM)xFeSe. By using X-ray diffraction technique, two sets of index peaks corresponding with different c-axis lattice constants are detected in the protonated samples, which belong to the newly formed phase of intercalated (EMIM)xFeSe and the residual FeSe, respectively. The superconductivity of (EMIM)xFeSe with Tc of 44.4 K is confirmed by resistivity and magnetic susceptibility measurements. Temperature dependence of resistivity with different applied magnetic fields reveals that the upper critical field Hc2 is quite high, while the irreversibility field Hirr is suppressed quickly with increasing temperature till about 20 K. This indicates that the resultant compound has a high anisotropy with a large spacing between the FeSe layers.

 We-code honorifics in Southern Amami Ōshima
 24 November 2021 Martha Tsutsui Billins (SOAS University of London) Abstract: This talk presents findings on honorifics in Southern Amami Ōshima, an endangered Ryukyuan language. Through fieldwork, this project explored bilingual Amami speakers’ language choices for expressing politeness in light of limited Amami honorific forms by collecting data from speakers in a range of different communicative events where honorifics would be expected. While Amami is no longer the unmarked code for politeness and deference, community members, including token speakers, still use Amami honorifics in day-to-day communication. Findings demonstrate that Amami speakers today draw on honorifics most commonly in the form of lexical touchstones, which they use as part of a we-code to index familiarity, intimacy, and localness. In this talk, I will focus on the functions and indexes of remaining Amami honorifics in the endangered language situation to which Amami belongs. YouTube: https://youtu.be/gXBzSBpRDdg

description: This chapter contains the results of strand one Scenarios of Future Schooling, Futures Thinking. The iterative mixed methods methodology study was used to answer the research questions in strand one: RQ1: How will participants respond to the scenarios as constructed in the OCED six Schooling for Tomorrow scenarios for the future of schooling and the HolonIQ five scenarios for the Future of Learning and Talent?’ RQ2: What does this suggest concerning participants’ perceptions, knowledge and values relating to future schooling? RQ3: What does this suggest for policy development and change in Australian schools?

This chapter also includes a discussion that shows the analysis conducted was consistent with the strand’s methodology approach, and how the analysis ties back to the research questions. Additionally, this chapter includes sample demographics, using tables to complement the summary. The process used to analyse transcripts from the participants conducted to uncover codes and themes is described in detail in chapter three. At each level of analysis, constant comparison was used to distil the data further, until themes emerged from the data. Included in the chapter are tables and graphics used to present detailed code and theme data, as well as graphics and vignettes from the individual interviews used to emphasise key themes and the resultant theory.
The Draft Chapter 4 will be updated in 2022 to include the data analysis of strand two of the research study The Emerging Forms of Learning. 
Electronic transport through a C$_{60}$ molecular bridge: The role of single and multiple contacts

description: The effects of different contact geometries, bond dimerization, and gate voltage on quantum transport through a C$_{60}$ molecule are studied by the Landauer-Büttiker formula based on the Green's function technique. It is shown that the number of contact points between the device electrodes and the molecule can play an important role in the electron conduction. The transmission is due to the resonant tunneling when the electrodes are contacted to one carbon atom of the molecule. In the case of multiple contacts, the interference effects are responsible for the change of the transmission through the C$_{60}$. The bond dimerization and a gate voltage shift the molecular levels and by adjusting the related parameters the electron conduction can be controlled.

description: Transistor aging is one of the major concerns that challenges designers in advanced technologies. It profoundly degrades the reliability of circuits during its lifetime as it slows down transistors resulting in errors due to timing violations unless large guardbands are included, which leads to considerable performance losses. When it comes to Neural Processing Units (NPUs), where increasing the inference speed is the primary goal, such performance losses cannot be tolerated. In this work, we are the first to propose a reliability-aware quantization to eliminate aging effects in NPUs while completely removing guardbands. Our technique delivers a graceful inference accuracy degradation over time while compensating for the aging-induced delay increase of the NPU. Our evaluation, over ten state-of-the-art neural network architectures trained on the ImageNet dataset, demonstrates that for an entire lifetime of 10 years, the average accuracy loss is merely 3%. In the meantime, our technique achieves 23% higher performance due to the elimination of the aging guardband.

Parameterization of the Angular Distribution of Gamma Rays Produced by p-p Interaction in Astronomical Environment

Year: 2007

description: We present the angular distribution of gamma rays produced by proton-proton interactions in parameterized formulae to facilitate calculations in astrophysical environments. The parameterization is derived from Monte Carlo simulations of the up-to-date proton-proton interaction model by Kamae et al. (2005) and its extension by Kamae et al. (2006). This model includes the logarithmically rising inelastic cross section, the diffraction dissociation process and Feynman scaling violation. The extension adds two baryon resonance contributions: one representing the Delta(1232) and the other representing multiple resonances around 1600 MeV/c^2. We demonstrate the use of the formulae by calculating the predicted gamma-ray spectrum for two different cases: the first is a pencil beam of protons following a power law and the second is a fanned proton jet with a Gaussian intensity profile impinging on the surrounding material. In both cases we find that the predicted gamma-ray spectrum to be dependent on the viewing angle.

description: Rate coefficients for rotational transitions in H_2 induced by H_2 impact are presented. Extensive quantum mechanical coupled-channel calculations based on a recently published (H_2)_2 potential energy surface were performed. The potential energy surface used here is presumed to be more reliable than surfaces used in previous work. Rotational transition cross sections with initial levels J <= 8 were computed for collision energies ranging between 0.0001 and 2.5 eV, and the corresponding rate coefficients were calculated for the temperature range 2 < T <10,000 K. In general, agreement with earlier calculations, which were limited to 100-6000 K, is good though discrepancies are found at the lowest and highest temperatures. Low-density-limit cooling functions due to para- and ortho-H_2 collisions are obtained from the collisional rate coefficients. Implications of the new results for non-thermal H_2 rotational distributions in molecular regions are also investigated.

description: Every Kauffman state σ of a link diagram D.K/ naturally defines a state surface Sσ whose boundary is K. For a homogeneous state σ, we show that K is a fibered link with fiber surface Sσ if and only if an associated graph G′ σ is a tree. As a corollary, it follows that for an adequate knot or link, the second and next-to-last coefficients of the Jones polynomial are the obstructions to certain state surfaces being fibers for K. This provides a dramatically simpler proof of a theorem of the author with Kalfagianni and Purcell.

description: We present results on the axial and the electromagnetic form factors of the nucleon, as well as on the first moments of the nucleon generalized parton distributions using maximally twisted mass fermions. We analyze two N f=2+1+1 ensembles having pion masses of 213 MeV and 373 MeV each at a different value of the lattice spacing. The lattice scale is determined using the nucleon mass computed on a total of 17 Nf=2+1+1 ensembles generated at three values of the lattice spacing, a. The renormalization constants are evaluated nonperturbatively with a perturbative subtraction of O(a2) terms. The moments of the generalized parton distributions are given in the MS̄ scheme at a scale of μ=2 GeV. We compare with recent results obtained using different discretization schemes. The implications on the spin content of the nucleon are also discussed. © 2013 American Physical Society.
Third harmonic flow of charged particles in Au + Au collisions at √sNN=200 GeV

Year: 2013
Subjects: nucl-ex

description: We report measurements of the third harmonic coefficient of the azimuthal anisotropy, v3, known as triangular flow. The analysis is for charged particles in Au+Au collisions at √sNN=200 GeV, based on data from the STAR experiment at the BNL Relativistic Heavy Ion Collider. Two-particle correlations as a function of their pseudorapidity separation are fit with narrow and wide Gaussians. Measurements of triangular flow are extracted from the wide Gaussian, from two-particle cumulants with a pseudorapidity gap, and also from event plane analysis methods with a large pseudorapidity gap between the particles and the event plane. These results are reported as a function of transverse momentum and centrality. A large dependence on the pseudorapidity gap is found. Results are compared with other experiments and model calculations. © 2013 American Physical Society.

metadata

description: Knowing what DDI is and understanding how it works and how to use it can be quite daunting—especially if you are not a programmer or coder. DDI can be quite a powerful metadata schema for the social sciences, but understanding the basics of it is a prerequisite to learning how to use it.

This workshop will tell you about the background of DDI, the different tools used to interpret it and how it is integrated into a data lifecycle workflow. There will be exercises to help you understand the different facets of DDI, thus allowing you to see its potential and power.

This is not a technical workshop; it is intended for those with no background in DDI. However, if you want a refresher in the whys and wherefores of it, then this workshop is also for you.
Stochastic Path Integral Analysis of the Continuously Monitored Quantum Harmonic Oscillator

description: We consider the evolution of a quantum simple harmonic oscillator in a general Gaussian state under simultaneous time-continuous weak position and momentum measurements. We deduce the stochastic evolution equations for position and momentum expectation values and the covariance matrix elements from the system's characteristic function. By generalizing the Chantasri-Dressel-Jordan (CDJ) formalism (Chantasri et al.~2013 and 2015) to this continuous variable system, we construct its stochastic Hamiltonian and action. Action extremization gives us the equations for the most-likely readout paths and quantum trajectories. For steady states of the covariance matrix elements, the analytical solutions for these most-likely paths are obtained. Using the CDJ formalism we calculate final state probability densities exactly starting from any initial state. We also demonstrate the agreement between the optimal path solutions and the averages of simulated clustered stochastic trajectories. Our results provide insights into the time dependence of the mechanical energy of the system during the measurement process, motivating their importance for quantum measurement engine/refrigerator experiments.

description: Any one-cusped hyperbolic manifold M with an unknotting tunnel x is obtained by Dehn filling a cusp of a two-cusped hyperbolic manifold. In the case where M is obtained by "generic" Dehn filling, we prove that r is isotopic to a geodesic, and characterize whether r is isotopic to an edge in the canonical decomposition of M. We also give explicit estimates (with additive error only) on the length of r relative to a maximal cusp. These results give generic answers to three long-standing questions posed by Adams, Sakuma and Weeks. We also construct an explicit sequence of one-tunnel knots in S3, all of whose unknotting tunnels have length approaching infinity.

Elliptic flow of identified hadrons in Au+Au collisions at √s NN=7.7-62.4 GeV
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2013
Subjects: nucl-ex

description: Measurements of the elliptic flow, v2, of identified hadrons (π±, K±, Ks0, p, p̄, φ, Λ, Λ̄, Ξ-, Ξ̄+, Ω-, Ω̄+) in Au+Au collisions at √sNN=7.7, 11.5, 19.6, 27, 39, and 62.4 GeV are presented. The measurements were done at midrapidity using the time-projection chamber and the time-of-flight detectors of the Solenoidal Tracker at RHIC experiment during the beam-energy scan program at Relativistic Heavy Ion Collider. A significant difference in the v2 values for particles and the corresponding antiparticles was observed at all transverse momenta for the first time. The difference increases with decreasing center-of-mass energy, √s NN (or increasing baryon chemical potential, μB), and is larger for the baryons as compared to the mesons. This implies that particles and antiparticles are no longer consistent with the universal number-of-constituent quark (NCQ) scaling of v2 that was observed at √sNN=200 GeV. However, for the selected group of particles (π+, K+, Ks0, p, Λ, Ξ-, Ω-) NCQ scaling at (mT-m0)/n q>0.4 GeV/c2 is not violated within ±10%. The v2 values for φ mesons at 7.7 and 11.5 GeV are approximately two standard deviations from the trend defined by the other hadrons at the highest measured pT values. © 2013 American Physical Society.
Purely 1-unrectifiable metric spaces and locally flat Lipschitz functions

description: We characterize compact metric spaces whose locally flat Lipschitz functions separate points uniformly as exactly those that are purely 1-unrectifiable, resolving a problem of Weaver. We subsequently use this geometric characterization to answer several questions in Lipschitz analysis. Notably, it follows that the Lipschitz-free space $\mathcal{F}(M)$ over a compact metric space $M$ is a dual space if and only if $M$ is purely 1-unrectifiable. Furthermore, we establish a compact determinacy principle for the Radon-Nikodým property (RNP) and deduce that, for any complete metric space $M$, pure 1-unrectifiability is actually equivalent to some well-known Banach space properties of $\mathcal{F}(M)$ such as the RNP and the Schur property. A direct consequence is that any complete, purely 1-unrectifiable metric space isometrically embeds into a Banach space with the RNP. Finally, we provide a possible solution to a problem of Whitney by finding a rectifiability-based description of 1-critical compact metric spaces, and we use this description to prove the following: a bounded turning tree fails to be 1-critical if and only if each of its subarcs has $σ$-finite Hausdorff 1-measure.

description: Starting from the analysis of both the Allegory of Lorenzo Lotto (Washington, National Gallery of Art) and its connections with Petrarch’s Canzoniere, this essay aims to study some Petrarchan interpretations of the mythological episode of Danaë. Following the double thematic thread of the excited gaze and the sublimation of desire, this analysis matches literary and visual sources, focusing on the illustrative set of the “Incunabolo Queriniano” produced by Antonio Grifo as well as on the moralised elaboration of the figure of Danaë in some Latin texts by Petrarch, and finally on some poetic ekphraseis by the Venetian Renaissance author Lodovico Dolce.
A Model-Driven Methodology for Automotive Cybersecurity Test Case Generation

Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Through international regulations (most prominently the latest UNECE regulation) and standards, the already widely perceived higher need for cybersecurity in automotive systems has been recognized and will mandate higher efforts for cybersecurity engineering. T he UNECE also demands the effectiveness of these engineering to be verified and validated through testing. T his requires both a significantly higher rate and more comprehensiveness of cybersecurity testing that is not effectively to cope with using current, predominantly manual, automotive cybersecurity testing techniques. To allow for comprehensive and efficient testing at all stages of the automotive life cycle, including supply chain parts not at band, and to facilitate efficient third party testing, as well as to test under real-world conditions, also methodologies for testing the cybersecurity of vehicular systems as a black box are necessary. T his paper therefore presents a model and attack tree-based approach to (semi-)automate automotive cybersecurity testing, as well as considerations for automatically black box-deriving models for the use in attack modeling.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this letter, Raine writes about love letters in the '20s.
Statistics of the number of equilibria in random social dilemma evolutionary games with mutation

description: In this paper, we study analytically the statistics of the number of equilibria in pairwise social dilemma evolutionary games with mutation where a game's payoff entries are random variables. Using the replicator-mutator equations, we provide explicit formulas for the probability distributions of the number of equilibria as well as other statistical quantities. This analysis is highly relevant assuming that one might know the nature of a social dilemma game at hand (e.g., cooperation vs coordination vs anti-coordination), but measuring the exact values of its payoff entries is difficult. Our delicate analysis shows clearly the influence of the mutation probability on these probability distributions, providing insights into how varying this important factor impacts the overall behavioural or biological diversity of the underlying evolutionary systems.
