Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Magnetic fields dominate most solar activities, there exist direct relations between solar flare and the distributions of magnetic field, and also its corresponding magnetic energy. In this paper, the statistical results about the relationships between the spatial magnetic field and solar flare are given basing on vector magnetic field observed by the Solar Magnetic Field Telescope (SMFT) at Huairou Solar Observing Station (HSOS). The spatial magnetic fields are obtained by extrapolated photosphere vector magnetic field observed by SMFT. There are 23 active regions with flare eruption are chosen as data samples, which were observed from 1997 to 2007. The results are as follows: 1. Magnetic field lines become lower after flare for 16(69%) active regions; 2. The free energy are decreased after flare for 17 (74%) active regions. It can conclude that for most active regions the changes of magnetic field after solar flare are coincident with the previous observations and studies.

description: Interstellar reddening corrections are necessary to reconstruct the intrinsic spectral energy distributions (SEDs) of accreting protostellar systems. The stellar SED determines the heating and chemical processes that can occur in circumstellar disks. Measurement of neutral hydrogen absorption against broad Lyman-$α$ emission profiles in young stars can be used to obtain the total H I column density (N(H I)) along the line of sight. We measure N(H I) with new and archival ultraviolet observations from the Hubble Space Telescope ($HST$) of 31 classical T Tauri and Herbig Ae/Be stars. The H I column densities range from log$_{10}$(N(H I)) $\approx 19.6 - 21.1$, with corresponding visual extinctions of A$_{V}$ $= 0.02 - 0.72$ mag, assuming an R$_{V}$ of 3.1. We find that the majority of the H I absorption along the line of sight likely comes from interstellar rather than circumstellar material. Extinctions derived from new $HST$ blue-optical spectral analyses, previous IR and optical measurements, and new X-ray column densities on average overestimate the interstellar extinction toward young stars compared to the N(H I) values by $\sim 0.6$ mag. We discuss possible explanations for this discrepancy in the context of a protoplanetary disk geometry.

description: The strength of the $E_{\rm p} = 1.842$ MeV resonance in the $^{40}$Ca(p,$γ$)$^{41}$Sc reaction is determined with two different methods: First, by an absolute strength measurement using calcium hydroxide targets, and second, relative to the well-determined strength of the resonance triplet at $E_α$ = 4.5 MeV in the $^{40}$Ca($α$,$γ$)$^{44}$Ti reaction. The present new value of $ωγ=(0.192\pm0.017)$ eV is 37% (equivalent to $3.5σ$) higher than the evaluated literature value. In addition, the ratio of the strengths of the 1.842 MeV $^{40}$Ca(p,$γ$)$^{41}$Sc and 4.5 MeV $^{40}$Ca($α$,$γ$)$^{44}$Ti resonances has been determined to be $0.0229\pm0.0018$. The newly corrected strength of the 1.842-MeV resonance can be used in the future as a normalization point for experiments with calcium targets.

description: Nucleosynthesis beyond Fe poses additional challenges not encountered when studying astrophysical processes involving light nuclei. Astrophysical sites and conditions are not well known for some of the processes involved. On the nuclear physics side, different approaches are required, both in theory and experiment. The main differences and most important considerations are presented for a selection of nucleosynthesis processes and reactions, specifically the $s$-, $r$-, $γ$-, and $νp$-processes. Among the discussed issues are uncertainties in sites and production conditions, the difference between laboratory and stellar rates, reaction mechanisms, important transitions, thermal population of excited states, and uncertainty estimates for stellar rates. The utility and limitations of indirect experimental approaches are also addressed. The presentation should not be viewed as confining the discussed problems to the specific processes. The intention is to generally introduce the concepts and possible pitfalls along with some examples. Similar problems may apply to further astrophysical processes involving nuclei from the Fe region upward and/or at high plasma temperatures. The framework and strategies presented here are intended to aid the conception of future experimental and theoretical approaches.

Objectivity in the Photonic Environment Through State Information Broadcasting

description: Recently, the emergence of classical objectivity as a property of a quantum state has been explicitly derived for a small object embedded in a photonic environment in terms of a spectrum broadcast form---a specific classically correlated state, redundantly encoding information about the preferred states of the object in the environment. However, the environment was in a pure state and the fundamental problem was how generic and robust is the conclusion. Here we prove that despite of the initial environmental noise the emergence of the broadcast structure still holds, leading to the perceived objectivity of the state of the object. We also show how this leads to a quantum Darwinism-type condition, reflecting classicality of proliferated information in terms of a limit behavior of the mutual information. Quite surprisingly, we find ,,singular points'' of the decoherence, which can be used to faithfully broadcast a specific classical message through the noisy environment.

description: We investigate some aspects of 2-flavor QCD with $m_u\not= m_d$ at low-energy, using the leading order chiral perturbation theory including anomaly effects. While nothing special happens at $m_u=0$ for the fixed $m_d\not=0$, the neutral pion mass becomes zero at two critical values of $m_u$, between which the neutral pion field condenses, leading to a spontaneously CP broken phase, the so-called Dashen phase. We also show that the "topological susceptibility" in the ChPT diverges at these two critical points. We briefly discuss a possibility that $m_u=0$ can be defined by the vanishing the "topological susceptibility. We finally analyze the case of $m_u=m_d=m$ with $θ=π$, which is equivalent to $m_u= - m_d=-m$ with $θ= 0$ by the chiral rotation. In this case, the $η$ condensation occurs at small $m$, violating the CP symmetry spontaneously. Deep in the $η$ condensation phase, three pions become Nambu-Goldstone bosons, but they show unorthodox behavior at small $m$ that $m_π^2 = O(m^2)$, which, however, is shown to be consistent with the chiral Ward-Takahashi identities.

description: In this presentation, Sergio (MA in Information and Library Studies at Aberystwyth University) summarised the main goals and processes established during his volunteering experience at KBR within the CAMille project. CAMille, founded in 2020 (ULB-KBR), is the (Belgian) Centre for Archives on the Media and Information. Two main research projects are currently carried out at CAMille: on the one hand, writing a history of Belgian journalism from the end of the 19th century to the present day, from a specific angle: the study of critical discourses; on the other hand, developing a database of Belgian journalists and media since 1830. This presentation touched upon the latter.

description: We apply a framework introduced in the late nineties to analyze load measurements in off-shore wind energy converters (WEC). The framework is borrowed from statistical physics and properly adapted to the analysis of multivariate data comprising wind velocity, power production and torque measurements, taken at one single WEC. In particular, we assume that wind statistics drives the fluctuations of the torque produced in the wind turbine and show how to extract an evolution equation of the Langevin type for the torque driven by the wind velocity. It is known that the intermittent nature of the atmosphere, i.e. of the wind field, is transferred to the power production of a wind energy converter and consequently to the shaft torque. We show that the derived stochastic differential equation quantifies the dynamical coupling of the measured fluctuating properties as well as it reproduces the intermittency observed in the data. Finally, we discuss our approach in the light of turbine monitoring, a particular important issue in off-shore wind farms.

description: Apoptosis, repair and senescence are tools which an organism can use in a risk management process that balances the threats posed by damaged, existing cells against the difficulty and cost of replacing them. If they are orchestrated effectively the organism can gain a degree of risk reduction, appropriate for a particular tissue and time of life, at minimum cost.
Where abundant resources allow, apoptosis eliminates risks posed by damaged cells. Where resources are constrained, senescence trades immediate threats posed by damaged cells for longer-term risks including inflammation, metastasis and epigenetic instability. Pushing risks into the future is consistent with an evolutionary need to keep an organism adequately healthy, for sufficiently long, that it can raise healthy offspring.
Negative consequences of senescence can be minimised by ensuring that senescence is rarely needed. Where senescence is unavoidable, it is desirable to engineer outcomes that halt proliferation without altering or damaging chromatin.

The cellular entropy of an organism will increase with age. Plentiful initial resources, and careful management of those resources, can delay but not eliminate the increase in cellular entropy and reduction in information as an organism ages. Increased risk, increased entropy and reduced information are closely related features of the aging process.

description: Driven by various kinds of noise, ensembles of limit cycle oscillators can synchronize. In this letter, we propose a general formulation of synchronization of the oscillator ensembles driven by common colored noise with an arbitrary power spectrum. To explore statistical properties of such colored noise-induced synchronization, we derive the stationary distribution of the phase difference between two oscillators in the ensemble. This analytical result theoretically predicts various synchronized and clustered states induced by colored noise and also clarifies that these phenomena have a different synchronization mechanism from the case of white noise.

description: The theory of quartet condensation is further developed. The onset of quartetting in homgeneous fermionic matter is studied with the help of an in-medium modified four fermion equation. It is found that at very low density quartetting wins over pairing. At zero temperature, in analogy to pairing, a set of equations for the quartet order parameter is given. Contrary to pairing, quartetting only exists for strong coupling and breaks down for weak coupling. Reasons for this finding are detailed. In an application to nuclear matter, the critical temperature for alpha particle condensation can reach values up to around 8 MeV. The disappearance of alpha particles with increasing density, i.e. the Mott transition, is investigated. In finite nuclei the Hoyle state, that is the second 0+ state of 12C is identified as an 'alpha-particle condensate' state. It is conjectured that such states also exist in heavier n-alpha nuclei, like 16O, 20Ne, etc. The sixth 0+ state in 16O is proposed as an analogue to the Hoyle state. The Gross-Pitaevski equation is employed to make an estimate of the maximum number of alpha particles a condensate state can contain. Possible quartet condensation in other systems is discussed briefly.

title: On linear, fractional, and submodular optimization
Creators: name: Koh, Zhuan Khye
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2023

description: In this thesis, we study four fundamental problems in the theory of optimization. 1. In fractional optimization, we are interested in minimizing a ratio of two functions over some domain. A well-known technique for solving this problem is the Newton– Dinkelbach method. We propose an accelerated version of this classical method and give a new analysis using the Bregman divergence. We show how it leads to improved or simplified results in three application areas. 2. The diameter of a polyhedron is the maximum length of a shortest path between any two vertices. The circuit diameter is a relaxation of this notion, whereby shortest paths are not restricted to edges of the polyhedron. For a polyhedron in standard equality form with constraint matrix A, we prove an upper bound on the circuit diameter that is quadratic in the rank of A and logarithmic in the circuit imbalance measure of A. We also give circuit augmentation algorithms for linear programming with similar iteration complexity. 3. The correlation gap of a set function is the ratio between its multilinear and concave extensions. We present improved lower bounds on the correlation gap of a matroid rank function, parametrized by the rank and girth of the matroid. We also prove that for a weighted matroid rank function, the worst correlation gap is achieved with uniform weights. Such improved lower bounds have direct applications in submodular maximization and mechanism design. 4. The last part of this thesis concerns parity games, a problem intimately related to linear programming. A parity game is an infinite-duration game between two players on a graph. The problem of deciding the winner lies in NP and co-NP, with no known polynomial algorithm to date. Many of the fastest (quasi-polynomial) algorithms have been unified via the concept of a universal tree. We propose a strategy iteration framework which can be applied on any universal tree.

description: During everyday web browsing and search users reveal many pieces of private information to third parties. Even though people report being concerned about their privacy online, they often do not take steps to protect it. This is known as the 'privacy paradox' in the literature. In this work we study two well-known strategies based on theories from the behavioral sciences, nudging and boosting, which encourage users to browse in a way that their private data are less exposed. First, an online survey (N=127) tested the comprehensibility and efficacy of various facts (boosts), before the most effective of these were evaluated against 'nudge' interventions previously shown to be efficacious in lab-studies. A three week naturalistic study (N=68) using a browser extension revealed that both nudges and boosts improve browsing privacy, as approximated by different measures. Boosts are also shown to improve user knowledge about privacy in the short term, but the benefit weakens over time.

description: Polarised electron and positron beams are key ingredients to the physics programme of future linear colliders. Due to the chiral nature of weak interactions in the Standard Model - and possibly beyond - the knowledge of the luminosity-weighted average beam polarisation at the $e^+e^-$ interaction point is of similar importance as the knowledge of the luminosity and has to be controlled to permille-level precision in order to fully exploit the physics potential. The current concept to reach this challenging goal combines measurements from Laser-Compton polarimeters before and after the interaction point with measurements at the interaction point. A key element for this enterprise is the understanding of spin-transport effects between the polarimeters and the interaction point as well as collision effects. We show that without collisions, the polarimeters can be cross-calibrated to 0.1 %, and we discuss in detail the impact of collision effects and beam parameters on the polarisation value relevant for the interpretation of the $e^+e^-$ collision data.

description: The objective of this review is to explore the state of interconnectedness in documenting workplace-related activity to facilitate informal learning. A number of transdisciplinary themes or elements are disaggregated into categories from the existing literature and then analysed through the use of systems-based tools to investigate the phenomenon. This review specifically, provides a multi-faceted approach in addressing the two research questions:How does documenting visual representation facilitate informal learning in the workplace? and; What findings from the investigation can be channelled towards building capability for Germany's Mittelstand Handwerk?Findings and discussion resulting from the review will inform further research into investigating a mixed methods study undertaken in the German Mittlestand. Collectively, this research effort will be used in the development of a faceted classification and validation model for industry.

description: Purpose: The aim of this retrospective cohort study is to assess the differences between patients seen at the start of the COVID-19 pandemic (COVID) with age, sex and insurance matched control patients (controls) one year prior and compare caries index (dmft/DMFT), loss to follow up and time to first recall. Methods: A retrospective chart review of new patients seen at a UIC affiliated clinic 3/1-14/20. Age and gender matched controls seen 3/1-31/19 were assessed. Inclusion criteria: patients <18, medically healthy, new to clinic. Assessed baseline dmft/DMFT, time (weeks) to first recall, and recall dmft/DMFT. Results: A total of 256 patients in each group were analyzed. Mean age 5.36 (SD=3.448); Female = 48.1%. There is significantly higher recall failure (COVID=90; Control=68; P=.038) and longer median lapsed time between initial and recall visits (COVID=42; Control=31; P<.001) for the COVID group than the control group. The dmft and DMFT for each group increased from initial to recall [COVID: baseline dmft=4.48 (4.094; Recall dmft=5.55(4.768); P<.001; Baseline DMFT=0.41(1.417); Recall DMFT=0.42(1.277); P<.001][Control: baseline dmft= 4.21(4.055); Recall dmft: COVID=4.49(4.242); P<.001; Baseline DMFT=0.44(1.354); Recall DMFT= 0.53(1.409; P<.001]. The change in mean dmft and DMFT between the COVID and control group was significantly higher in the COVID group (P<.001; P=.042). Conclusions: Patients seen during the pandemic time frame were loss to follow up (lacked recalls) at higher rates, had delayed recalls and had a higher caries experience (dmft) compared with patients seen one year prior to the onset of the COVID-19 pandemic. The pandemic negatively impacted pediatric oral health parameters.

description: Aql X-1 is the most prolific low mass X-ray binary transient hosting a neutron star. In this paper we focus on the return to quiescence following the 2010 outburst of the source. This decay was monitored thanks to 11 pointed observations taken with XMM-Newton, Chandra and Swift. The decay from outburst to quiescence is very fast, with an exponential decay characteristic time scale of ~2 d. Once in quiescence the X-ray flux of Aql X-1 remained constant, with no further signs of variability or decay. The comparison with the only other well-monitored outburst from Aql X-1 (1997) is tail-telling. The luminosities at which the fast decay starts are fully compatible for the two outbursts, hinting at a mechanism intrinsic to the system and possibly related to the neutron star rotation and magnetic field (i.e., the propeller effect). In addition, for both outbursts, the decay profiles are also very similar, likely resulting from the shut-off of the accretion process onto the neutron star surface. Finally, the quiescent neutron star temperatures at the end of the outbursts are well consistent with one another, suggesting a hot neutron star core dominating the thermal balance. Small differences in the quiescent X-ray luminosity among the two outbursts can be attributed to a different level of the power law component.

description: Background Artificial intelligence (AI) is one of the most promising areas in medicine with many possibilities for improving health and wellness. Already today, diagnostic decision support systems may help patients to estimate the severity of their complaints. This fictional case study aimed to test the diagnostic potential of an AI algorithm for common sports injuries and pathologies. Methods Based on a literature review and clinical expert experience, five fictional “common” cases of acute, and subacute injuries or chronic sport-related pathologies were created: Concussion, ankle sprain, muscle pain, chronic knee instability (after ACL rupture) and tennis elbow. The symptoms of these cases were entered into a freely available chatbot-guided AI app and its diagnoses were compared to the pre-defined injuries and pathologies. Results A mean of 25–36 questions were asked by the app per patient, with optional explanations of certain questions or illustrative photos on demand. It was stressed, that the symptom analysis would not replace a doctor’s consultation. A 23-yr-old male patient case with a mild concussion was correctly diagnosed. An ankle sprain of a 27-yr-old female without ligament or bony lesions was also detected and an ER visit was suggested. Muscle pain in the thigh of a 19-yr-old male was correctly diagnosed. In the case of a 26-yr-old male with chronic ACL instability, the algorithm did not sufficiently cover the chronic aspect of the pathology, but the given recommendation of seeing a doctor would have helped the patient. Finally, the condition of the chronic epicondylitis in a 41-yr-old male was correctly detected. Conclusions All chosen injuries and pathologies were either correctly diagnosed or at least tagged with the right advice of when it is urgent for seeking a medical specialist. However, the quality of AI-based results could presumably depend on the data-driven experience of these programs as well as on the understanding of their users. Further studies should compare existing AI programs and their diagnostic accuracy for medical injuries and pathologies.

description: The analogies between successive interference cancellation (SIC) in slotted ALOHA framework and iterative belief-propagation erasure-decoding, established recently, enabled the application of the erasure-coding theory and tools to design random access schemes. This approach leads to throughput substantially higher than the one offered by the traditional slotted ALOHA. In the simplest setting, SIC progresses when a successful decoding occurs for a single user transmission. In this paper we consider a more general setting of a channel with capture and explore how such physical model affects the design of the coded random access protocol. Specifically, we assess the impact of capture effect in Rayleigh fading scenario on the design of SIC-enabled slotted ALOHA schemes. We provide analytical treatment of frameless ALOHA, which is a special case of SIC-enabled ALOHA scheme. We demonstrate both through analytical and simulation results that the capture effect can be very beneficial in terms of achieved throughput.

Data Sparsity in Recommender Systems: Collaborative Neighbors Enrichment
Creators: name: Fan, Ziwei
Publisher: name: University of Illinois at Chicago
Year: 2023

description: In recommender systems, collaborative filtering is the most predominant idea for modeling users' preferences on items. Collaborative filtering learns user-user similarities and item-item correlations by representing users/items with their interacted items/users (i.e., collaborative neighbors). However, the data sparsity characteristic of user-item interactions poses a great challenge to users and items modeling. Moreover, most users and items have limited interaction, which means users and items both follow the power-law distribution based on the number of interactions. This data sparsity issue limits the representation learning of users/items due to insufficient collaborative neighbors. In this dissertation, I will introduce our recent work on empowering different methods in alleviating the data sparsity problem in recommender systems, in perspectives of data augmentations, novel metric learning, and the usage of additional information to help expand the collaborative neighbors. In this first part, I present an approach to augment pseudo-history for short user sequences reversely. In the second and third parts, a novel metric based on Wasserstein distance is introduced to enhance neighbors via collaborative transitivity. In the fourth part, a multi-relational Transformer is proposed to incorporate additional item relationships. Lastly, I will introduce to apply Wasserstein distance into contrastive learning to enhance the robustness and efficiency of data augmentations.

description: Storing digital information, ensuring the accuracy, steady and uninterrupted access to the data are considered as fundamental challenges in enterprise-class organizations and companies. In recent years, new types of storage systems such as solid state disks (SSD) have been introduced. Unlike hard disks that have mechanical structure, SSDs are based on flash memory and thus have electronic structure. Generally a SSD consists of a number of flash memory chips, some buffers of the volatile memory type, and an embedded microprocessor, which have been interconnected by a port. This microprocessor run a small file system which called flash translation layer (FTL). This software controls and schedules buffers, data transfers and all flash memory tasks. SSDs have some advantages over hard disks such as high speed, low energy consumption, lower heat and noise, resistance against damage, and smaller size. Besides, some disadvantages such as limited endurance and high price are still challenging. In this study, the effort is to combine two common technologies - SLC and MLC chips - used in the manufacture of SSDs in a single SSD to decrease the side effects of current SSDs. The idea of using multi-layer SSD is regarded as an efficient solution in this field.

description: The differential cross section for the exclusive dp -> 3Heπ+π- reaction has been measured with high resolution and large statistics over a large fraction of the backward 3He hemisphere at the excess energy 265 MeV using the COSY-ANKE magnetic spectrometer. Though the well-known ABC enhancement is observed in the π+π- spectrum, the differences detected between the π+3He and π-3He invariant-mass distributions show that there must be some isospin-one ππ production even at relatively low excess energies. The invariant-mass differences are modeled in terms of the sequential decay N*(1440) -> Delta(1232)π -> Nππ.

A model for the onset of oscillations near the stopping angle in an inclined granular flow

description: We propose an explanation for the onset of oscillations seen in numerical simulations of dense, inclined flows of inelastic, frictional spheres. It is based on a phase transition between disordered and ordered collisional states that may be interrupted by the formation of force chains. Low frequency oscillations between ordered and disordered states take place over weakly bumpy bases; higher-frequency oscillations over strongly bumpy bases involve the formation of particle chains that extend to the base and interrupt the phase change. The predicted frequency and amplitude of the oscillations induced by the unstable part of the equation of state are similar to those seen in the simulations and they depend upon the contact stiffness in the same way. Such oscillations could be the source of sound produced by flowing sand.

Impact of Genetics on Coronary Heart Disease, Low-Density Lipoprotein Cholesterol Levels and Control
Creators: name: Hutten, Christina G
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Hypercholesterolemia is a prevalent risk factor for coronary heart disease (CHD) which is a leading cause of death among Hispanics/Latinos. Rates of cholesterol awareness and treatment are low in this population. Genetic risk scores (GRS) have been used in populations of European ancestry to identify those at higher risk for CHD events. The purpose of this study was to apply two previously constructed GRS, 1) to assess their association with prevalent and incident CHD, and low-density lipoprotein (LDL) cholesterol levels in a diverse cohort of Hispanics/Latinos 2) to evaluate the association of the GRS with LDL control among statin users, and 3) to evaluate whether GRS improves prediction of CHD over traditional risk factors. We utilized baseline and longitudinal data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a prospective study that enrolled 16,415 Hispanic/Latino adults aged 18-74 years from four U.S. communities between 2008-2011. The two GRS were found to be associated with prevalent and incident CHD, and LDL cholesterol levels, respectively; however, when stratified by genetic admixture, associations were more robust among participants with higher proportions of European ancestry. The predictive value of traditional risk factors was improved when combined with the GRS for CHD. The GRS associated with LDL was positively associated with LDL levels. Among participants taking statins, those at highest genetic risk had the lowest odds of LDL control. The results highlight the need for additional studies to evaluate and optimize risk prediction using cumulative genetic risk in a diverse Hispanic/Latino population. These findings support the development of Hispanic/Latino-specific GRS for early life risk prediction, mitigation of CHD events and LDL control. Importantly, this study is among the first to investigate GRS associated with CHD, LDL levels, and LDL control within a Hispanic/Latino population and helps to address the dearth of genetic data for an underrepresented population. As precision medicine enters clinical practice, the overall results of this study have implications for prevention of widening health disparities among Hispanics/Latinos living in the U.S and for advocating for population diversity in genetic research.
