description: BACKGROUND: Aortic arch reconstruction in neonates is commonly performed using deep hypothermic circulatory arrest. However, concerns have arisen regarding potential adverse neurologic outcomes from this complex procedure, raising questions about the best arterial cannulation approach for cerebral perfusion and effective systemic hypothermia. In this study, we use computational fluid dynamics to investigate the effect of different cannulation strategies in neonates.
METHODS: We used a realistic template of a hypoplastic neonatal aorta as the base geometry to investigate four cannulation options: (1) right innominate artery, (2) innominate root, (3) patent ductus arteriosus (PDA), or (4) innominate root and PDA. Performance was evaluated according to the numerically predicted cerebral and systemic flow distributions compared with physiologic perfusion under neonatal conditions.
RESULTS: The four cannulation strategies were associated with different local hemodynamics; however, this did not translate into any significant effect on the measured flow distributions. The largest difference only represented 0.8% of the cardiac output and was measured in the innominate artery, which received 23.2% of the cardiac output in option 3 vs 24% in option 4. Pulmonary artery snaring benefited all systemic vessels uniformly.
CONCLUSIONS: Because of the very high vascular resistances in neonates, downstream vascular resistances dictated flow distribution to the different vascular beds rather than the cannulation strategy, allowing the surgical team to choose their method of preference. However, patients with aortic coarctation warrant further investigation and will most likely benefit from a 2-cannulae approach (option 4).

description: L'éclairage artificiel dans les immeubles à bureaux et les écoles constitue une source importante de consommation d'énergie électrique. En outre, les systèmes de conditionnement de l'air consomment de l'énergie et peuvent être nécessaires pour extraire la chaleur produite par les appareils d'éclairage. La consommation de l'énergie se calcule en multipliant la puissance d'entrée (en kilowatts) par les heures de service. Pour réduire l'énergie consommée, il faut tenir compte à la fois de la puissance et des heures de service. La puissance d'entrée peut être réduite en diminuant les niveaux d'éclairement généraux, en adoptant des normes d'éclairage sélectives et en remplacant les sources d'éclairage inefficaces. Les heures de service peuvent aussi être réduites en prévoyant des dispositifs de coupure particuliers et de commande automatique de l'éclairage en fonction de la lumière du jour disponible et de l'aménagement de l'espace.

description: Mobile micro-clouds are promising for enabling performance-critical cloud applications. However, one challenge therein is the dynamics at the network edge. In this paper, we study how to place service instances to cope with these dynamics, where multiple users and service instances coexist in the system. Our goal is to find the optimal placement (configuration) of instances to minimize the average cost over time, leveraging the ability of predicting future cost parameters with known accuracy. We first propose an offline algorithm that solves for the optimal configuration in a specific look-ahead time-window. Then, we propose an online approximation algorithm with polynomial time-complexity to find the placement in real-time whenever an instance arrives. We analytically show that the online algorithm is $O(1)$-competitive for a broad family of cost functions. Afterwards, the impact of prediction errors is considered and a method for finding the optimal look-ahead window size is proposed, which minimizes an upper bound of the average actual cost. The effectiveness of the proposed approach is evaluated by simulations with both synthetic and real-world (San Francisco taxi) user-mobility traces. The theoretical methodology used in this paper can potentially be applied to a larger class of dynamic resource allocation problems.

Status of the LEGEND Neutrinoless Double Beta Decay Search
Creators: name: Wiseman, Clinton
Publisher: name: Zenodo
Year: 2020

description: The LEGEND collaboration is searching for the ultra-rare process of neutrinoless double beta decay in 76Ge. The discovery of this decay would establish that the neutrino is its own antiparticle, with far-reaching implications in explaining the matter-antimatter asymmetry in our universe. A ton-scale array of germanium detectors, fabricated with ultra-low background materials and operated in a scintillating liquid argon veto, can make a discovery at a half-life beyond $10^{28}$ years, more than an order-of-magnitude advance over current-generation experiments. The first stage, LEGEND-200, is under construction at LNGS, with detectors in production and commissioning data being analyzed. R&D for LEGEND-1000 is also underway, with an ultimate goal of reducing radioactive backgrounds at the 76Ge decay energy (2039 keV) to a world-leading < 0.03 cts/(FWHM-t-yr). In this work, I present the current outlook for LEGEND.

description: Current wide-area radio surveys are dominated by active galactic nuclei, yet many of these sources have no identified optical counterparts. Here we investigate whether one can constrain the nature and properties of these sources, using Fanaroff-Riley type II (FRII) radio galaxies as probes. These sources are easy to identify since the angular separation of their lobes remains almost constant at some tens of arcseconds for z>1. Using a simple algorithm applied to the FIRST survey, we obtain the largest FRII sample to date, containing over ten thousand double-lobed sources. A subset of 459 sources is matched to SDSS quasars. This sample yields a statistically meaningful description of the fraction of quasars with lobes as a function of redshift and luminosity. This relation is combined with the bolometric quasar luminosity function, as derived from surveys at IR to hard X-ray frequencies, and a disc-lobe correlation to obtain a robust prediction for the density of FRIIs on the radio sky. We find that the observed density can be explained by the population of known quasars, implying that the majority of powerful jets originate from a radiatively efficient accretion flow with a linear jet-disc coupling. Finally, we show that high-redshift jets are more often quenched within 100 kpc, suggesting a higher efficiency of jet-induced feedback into their host galaxies.

description: In the present work the classical problem of harmonic oscillator in the hyperbolic space $H_2^2$: $z_0^2+z_1^2-z_2^2-z_3^2=R^2$ has been completely solved in framework of Hamilton-Jacobi equation. We have shown that the harmonic oscillator on $H_2^2$, as in the other spaces with constant curvature, is exactly solvable and belongs to the class of maximally superintegrable system. We have proved that all the bounded classical trajectories are closed and periodic. The orbits of motion are ellipses or circles for bounded motion and ultraellipses or equidistant curve for infinite ones.

Corrosion protection

description: At the design stage, engineers and owners have the most influence on the future durability of post-tensioned concrete bridges. Yet design guidelines are not clear on what corrosion protection methods are appropriate for a given exposure environment. Current specifications do not ignore corrosion protection. However, many simply instruct the designer to protect the anchorage and prestressing steel from corrosion, leaving the selection of the appropriate method to the engineer’s experience. As well, many decision-makers do not have a good understanding of how post-tensioning works, how it can be protected from corrosion, or how much it will cost to increase the durability of the posttensioning system. This thesis includes a description of post-tensioning systems and corrosion protection methods as a reference for those not intimately familiar with the mechanisms and protection approaches. It gives the results of an industry cost survey that shows the expected cost increases, as a percentage of total initial construction cost, from including corrosion protection in the design. As well, life cycle analyses for several methods show their potential to save the owner money over the bridge’s expected life. Additionally, this thesis examines several current or proposed design specifications for their corrosion protection guidance. A new combination of these guidelines is proposed to give a more logical and designer-friendly option
Strong experimental guarantees in ultrafast quantum random number generation

description: We describe a methodology and standard of proof for experimental claims of quantum random number generation (QRNG), analogous to well-established methods from precision measurement. For appropriately constructed physical implementations, lower bounds on the quantum contribution to the average min-entropy can be derived from measurements on the QRNG output. Given these bounds, randomness extractors allow generation of nearly perfect "ε-random" bit streams. An analysis of experimental uncertainties then gives experimentally derived confidence levels on the ε randomness of these sequences. We demonstrate the methodology by application to phase-diffusion QRNG, driven by spontaneous emission as a trusted randomness source. All other factors, including classical phase noise, amplitude fluctuations, digitization errors and correlations due to finite detection bandwidth, are treated with paranoid caution, i.e., assuming the worst possible behaviors consistent with observations. A data-constrained numerical optimization of the distribution of untrusted parameters is used to lower bound the average min-entropy. Under this paranoid analysis, the QRNG remains efficient, generating at least 2.3 quantum random bits per symbol with 8-bit digitization and at least 0.83 quantum random bits per symbol with binary digitization, at a confidence level of 0.99993. The result demonstrates ultrafast QRNG with strong experimental guarantees.

Publisher: name: Zenodo
Year: 2020

description: The detection of coherent neutrino-nucleus scattering (CEvNS) opens a new window to study the fundamental properties of neutrinos and to probe physics beyond the Standard Model of Particle Physics. NUCLEUS is a novel cryogenic neutrino experiment which allows for precision measurements of CEvNS at unprecedentedly low energies. It is based on recently demonstrated cryogenic detectors with nuclear-recoil energy thresholds in the 10eV regime. NUCLEUS will be installed at a new experimental site in between the two 4.25GW reactor cores of the CHOOZ B nuclear power plant in France, aiming to start operation in 2022. The high cross-section of CEvNS will enable a 10% precision measurement of the process with a 10g detector in 1 year of data taking. This poster presents the design, the current status and the physics potential of the experiment.

description: We study the fate of the Ising model and its universal properties when driven by a rapid periodic drive and weakly coupled to a bath at equilibrium. The far from equilibrium steady-state regime of the system is accessed by means of a Floquet mean field approach. We show that, depending on the details of the bath, the drive can strongly renormalize the critical temperature to higher temperatures, modify the critical exponents, or even change the nature of the phase transition from second to first order after the emergence of a tricritical point. Moreover, by judiciously selecting the frequency of the field and by engineering the spectrum of the bath, one can drive a ferromagnetic Hamiltonian to an antiferromagnetically ordered phase and vice-versa.

description: Attachment of thoracic artificial lungs (TALs) can increase right ventricular (RV) afterload and decrease cardiac output (CO) under certain conditions. However, there is no established means of predicting the extent of RV dysfunction. The zeroth harmonic impedance modulus, Z0, was thus examined to determine its effectiveness at predicting CO during high afterload TAL attachment. The MC3 Biolung was attached in four adult sheep groups based on baseline (BL) pulmonary vascular resistance and TAL attachment mode: normal, parallel (n=7); normal, series (n=7); chronic pulmonary hypertension, parallel (n=5), and chronic pulmonary hypertension, series (n=5). The resistance of each attachment mode was increased incrementally and instantaneous pulmonary system hemodynamic data were acquired at each increment. The change in Z0 from BL, DeltaZ0, and percent change in CO (DeltaCO%) were then calculated to determine their relationship. The DeltaCO% varied significantly with DeltaZ0 (p
Search for Neutrino Emission from X-ray Binaries with IceCube

description: The observation of very-high-energy gamma rays from X-ray binaries implies the possibility that they are cosmic ray (CR) sources in the Milky Way. The compact object in a binary system, e.g. a neutron star or black hole, can be the site for CR acceleration. Interactions of CRs can happen in the jet of the compact object, the wind, or the atmosphere of the companion star which produce high-energy photons and neutrinos. As neutrinos act as the smoking-gun of hadronic mechanisms in the source, we perform a time-dependent analysis searching for neutrino emission from X-ray binaries with IceCube. In this analysis, we make use of lightcurves of those sources, looking for flaring features in the 10 yr IceCube muon neutrino data.

CP-violation measurement in DUNE with Sub-GeV Atmospheric Neutrinos
Creators: name: Soler, Ivan Jesus Martinez
Publisher: name: Zenodo
Year: 2020

description: Liquid Argon TPC (LarTPC) detectors have a unique capability in measuring low energy neutrino signals. In this work, we study the DUNE sensitivity to the CP-violation phase using sub-GeV atmospheric neutrinos. LarTPCs would reconstruct with high accuracy the track and the energy of low-energy charged particles, allowing to infer the energy and direction of sub-GeV neutrinos with unprecedented precision. Combining the sensitivity of events with 0,1 and 2 observable protons in the final state, the results indicate that DUNE would be able to exclude several delta_CP values at more than 3\sigma of CL using only atmospheric neutrinos.

description: The phase transition from a topological insulator to a trivial band insulator is studied by angle-resoled photoemission spectroscopy on Bi$_{2-x}$In$_{x}$Se$_{3}$ single crystals. We first report the complete evolution of the bulk band structures throughout the transition. The robust surface state and the bulk gap size ($\sim$ 0.50 eV) show no significant change upon doping for $x$ = 0.05, 0.10 and 0.175. At $x$ $\geq$ 0.225, the surface state completely disappears and the bulk gap size increases, suggesting a sudden gap-closure and topological phase transition around $x \sim$ 0.175$-$0.225. We discuss the underlying mechanism of the phase transition, proposing that it is governed by the combined effect of spin-orbit coupling and interactions upon band hybridization. Our study provides a new venue to investigate the mechanism of the topological phase transition induced by non-magnetic impurities.

Detection of Cosmic Muon Spallation Background in LS-Detector Using Machine Learning
Creators: name: Zhenghao Fu
Publisher: name: Zenodo
Year: 2020

description: Neutrinos are the most abundant but also the most mysterious fermions in the universe. In rare event searches like those for neutrinoless double-beta decay (0νββ), one of major backgrounds is caused by cosmic muon spallation. To remove these background events, a precise method with high efficiency is required to separate them from signal events. Machine learning offers a solution to this problem. More specifically, for the spherical detector in KamLAND-Zen, convolutional neural networks (CNNs) based on a spherical system provides a way to classify the data. Besides the classification, a method related to regional CNNs is also developed, aiming to reconstruct the direction of particles in a detector. This poster will cover the concept and usage of spherical CNNs for KamLAND-Zen's data, and the current performance of the direction-determination using simulations.

Abstract This research aimed to determine antioxidative effect on lipids of eugenol, extracted from clove
flowers. Method Meatball is a very popular meat product obtained from a mixture of minced pork meat,
salt, sugar, additives (phosphate, glutamate and antioxidants). The antioxidative effect of eugenol,
extracted using alcohol reflux extraction methods, on lipid oxidation in pork meatballs compared with
that of butylated hydroxy toluene (BHT) were studied. The study meatball samples were divided into
four groups according to the antioxidant: C (control meatballs),0.02% BHT (meatballs supplemented
with 0.02%BHT), 0.02% eugenol oil (meatballs supplemented with 0.02% eugenol oil) and 0.04%
eugenol oil (meatballs supplemented with 0.04% eugenol oil). Lipid oxidation was assessed by
determination of thiobarbituric acid reactive substances (TBARs) and peroxide value (POV). All pork
samples were boiled at 90-95°C for 3-5 minutes and then stored in the vacuum bags in the refrigerator
(4°C) for 0,1, 3, 5, 7 and 9 days before lipid oxidation levels were measured using TBARS and POV. All
experiments were performed in triplicate. Results TBARS and POV were found to be significantly lower
in all treatment groups compared to the control groups during the storage period. At the addition level of
0.02% eugenol (0.2 g/kg in total meat), eugenol has the same inhibitory effect on lipid oxidation as 0.02%
BHT (0.2 g/kg in total meat). Moreover, eugenol at the level of 0.04% (0.4 g/kg eugenol in total meat)
was more effective in inhibiting lipid oxidation than both 0.02% BHT and 0.02% eugenol. These results
showed that eugenol, extracted from clove flowers, is equally effective in inhibiting the oxidation of
lipids in meat. This study indicates eugenol may be a promising natural antioxidant during meat storage.

description: CUPID-Mo is searching for neutrinoless double beta decay with enriched Li$_{2}$$^{100}$MoO$_4$ scintillating crystals, operating at the Modane underground laboratory. During the first physics runs, started at the beginning of 2019, CUPID-Mo collected an exposure of more than 2 kg.y. The data validates the high level of radiopurity of the crystals and the excellent alpha-particle rejection. In this work we present a model to reconstruct the CUPID-Mo energy spectra. The model is built from the Monte Carlo simulations of the background sources and exploits their distinctive signatures. The investigation of the background sources in CUPID-Mo is precious to finely tune the construction choices of the next-generation experiment CUPID.

description: The details of bulge formation via collapse, mergers, secular processes or their interplay remain unresolved. To start answering this question and quantify the importance of distinct mechanisms, we mapped a sample of three galactic bulges using data from the integral field spectrograph WiFeS on the ANU 2.3m telescope in Siding Spring Observatory. Its high resolution gratings (R=7000) allow us to present a detailed kinematic and stellar population analysis of their inner structures with classical and novel techniques. The comparison of those techniques calls for the necessity of inversion algorithms in order to understand complex substructures and separate populations. We use line-strength indices to derive SSP-equivalent ages and metallicities. Additionally, we use full spectral fitting methods, here the code STECKMAP, to extract their star formation histories. The high quality of our data allows us to study the 2D distribution of different stellar populations (i.e. young, intermediate, and old). We can identify their dominant populations based on these age-discriminated 2D light and mass contribution. In all galactic bulges studied, at least 50% of the stellar mass already existed 10 Gyrs ago, more than currently predicted by simulations. A younger component (age between 1 to 8 Gyrs) is also prominent and its present day distribution seems to be affected much more strongly by morphological structures, especially bars, than the older one. This in-depth analysis of the three bulges supports the notion of increasing complexity in their evolution, likely to be found in numerous bulge structures if studied at this level of detail, which cannot be achieved by mergers alone and require a non-negligible contribution of secular evolution.

Cherenkov Separation in Slow Scintillators
Creators: name: Paton, Josephine
Publisher: name: Zenodo
Year: 2020

description: Separation of Cherenkov and scintillation signal for electron events extending below 1MeV is demonstrated on a bench top scale. This is achieved using highly efficient slow fluors, with linear alkylbenzene (LAB) as the primary solvent, to create liquid scintillator solutions with rise times of several ns or more and decay times of tens of ns. Such mixtures show a clear timing separation between the Cherenkov and scintillation signal, allowing directional information to be extracted from the event while maintaining a high light yield. This could have significant consequences for the development of large-scale liquid scintillation detectors, potentially providing good directional information about elastic scattering neutrino events down to low energies. Such information could be particularly useful in the removal of backgrounds from studies of solar neutrinos, neutrinoless double beta decay, supernovae neutrinos and reactor anti-neutrinos, amongst others.

It is therefore important to identify patients at risk a priori. However, prognostic models derived from multivariate analyses have had limited predictive power.
METHODS: This study retrospectively analyzed the records of 183 LVAD recipients between May 1996 and October 2009; of these, 27 later required a RVAD (RVAD(+)) and 156 remained on LVAD only (RVAD(-)) until transplant or death. A decision tree model was constructed to represent combinatorial non-linear relationships of the pre-operative data that are predictive of the need for RVAD support.
RESULTS: An optimal set of 8 pre-operative variables were identified: transpulmonary gradient, age, right atrial pressure, international normalized ratio, heart rate, white blood cell count, alanine aminotransferase, and the number of inotropic agents. The resultant decision tree, which consisted of 28 branches and 15 leaves, identified RVAD(+) patients with 85% sensitivity, RVAD(-) patients with 83% specificity, and exhibited an area under the receiver operating characteristic curve of 0.87.
CONCLUSIONS: The decision tree model developed in this study exhibited several advantages compared with existing risk scores. Quantitatively, it provided improved prognosis of RV support by encoding the non-linear, synergic interactions among pre-operative variables. Because of its intuitive structure, it more closely mimics clinical reasoning and therefore can be more readily interpreted. Further development with additional multicenter, longitudinal data may provide a valuable prognostic tool for triage of LVAD therapy and, potentially, improve outcomes.
Sorcery Cases in Papua New Guineas Village Courts: Legal Innovation Part IV

description: This In Brief argues that the repeal of Papua New Guinea's Sorcery Act 1971 has been functionally irrelevant for village courts, which face the issue of sorcery with far more frequency than higher courts ever did. The Sorcery Act, a piece of late colonial-era legislation that was a half-hearted attempt to reflect the social milieu of Papua New Guinea, criminalised the use of sorcery for 'evil purposes'. It was repealed in 2013 in the wake of several high-profile and gruesome killings related to sorcery accusations, because of a widespread perception that the Act could make available a defence in cases involving violence toward suspected sorcerers. Dissatisfaction with the Act had been building for some time, even though a sorcery-related defence has almost never succeeded in court (Demian 2011; Forsyth 2015). In addition to repealing the Act, Prime Minister Peter O'Neill introduced draconian penal measures such as the extension of the death penalty to sorcery-related murders (BBC News 2013).

description: Current thoracic artificial lungs (TALs) have blood flow impedances greater than the natural lungs, which can result in abnormal pulmonary hemodynamics. This study investigated the impedance and gas transfer performance of a compliant TAL (cTAL). Fluid-structure interaction analysis was performed using ADINA (ADINA R&D Inc., Watertown, MA) to examine the effect of the inlet and outlet expansion angle, θ, on device impedance and blood flow patterns. Based on the results, the θ = 45° model was chosen for prototyping and in vitro testing. Glycerol was pumped through this cTAL at 2, 4, and 6 L/min at 80 and 100 beats/min, and the zeroth and first harmonic impedance moduli, Z(0) and Z(1), were calculated. Gas transfer testing was conducted at blood flow rates of 3, 5, and 7 L/min. Fluid-structure interaction results indicated that the 45° model had an ideal combination of low impedance and even blood flow patterns and was thus chosen for prototyping. In vitro, Z(0) = 0.53 ± 0.06 mm Hg/(L/min) and Z(1) = 0.86 ± 0.08 mm Hg/(L/min) at 4 L/min and 100 beats/min. Outlet PO(2) and SO(2) values were above 200 mm Hg and 99.5%, respectively, at each flow rate. Thus, the cTAL had lower impedance than hard shell TALs and excellent gas transfer.
Daya Bay Reactor Antineutrino Flux and Spectrum Measurement
Creators: name: Mandujano, Roberto Carlos
Publisher: name: Zenodo
Year: 2020

description: This poster will present the latest results of the reactor antineutrino flux and spectrum measurement at Daya Bay. The Daya Bay Reactor Antineutrino Experiment employs eight antineutrino detectors in three different experimental halls to detect reactor neutrinos coming from six 2.9 GW$_{th}$ commercial nuclear reactors. The latest absolute reactor antineutrino flux measurement with an improved detection efficiency uncertainty continues to confirm the discrepancy with the Huber-Mueller model (known as the reactor antineutrino anomaly) with a measured to predicted yield ratio of 0.952 ± 0.014 (exp.) ± 0.023 (model). From the observed evolution with fuel composition, the individual 235U and 239Pu antineutrino yields and energy spectra are extracted for the first time with commercial reactors. The data are consistent with 235U mismodeling being the main contributor to the reactor antineutrino anomaly.
Segmentation Neural Networks for Particle Identification in ProtoDUNE
Creators: name: Sarasty, Carlos
Publisher: name: Zenodo
Year: 2020

description: This poster presents the application of sparse convolutional neural networks in three dimensions in the ProtoDUNE Liquid Argon Time Projection Chamber (LArTPC) detector, building on previous applications of the technique in other LArTPCs. Sparse convolutions allow for computationally efficient processing of very large and high-resolution three-dimensional images, making them a natural fit for fine-grained particle detectors. The use of segmentation techniques allows for particle ID to be performed on individual 3D hits, without the need to produce higher-level objects. This poster will discuss input production and network architecture, present training and inference benchmarking on ProtoDUNE simulation, and describe techniques for defining ground truth using the underlying simulation. Particle identification accuracies are presented for a range of particle classes, and the application of this technique for ProtoDUNE cross-section measurements is discussed.
A mathematical study of meteo and landslide tsunamis : The Proudman resonance

description: In this paper, we want to understand the Proudman resonance. It is a resonant respond in shallow waters of a water body on a traveling atmospheric disturbance when the speed of the disturbance is close to the typical water wave velocity. We show here that the same kind of resonance exists for landslide tsunamis and we propose a mathematical approach to investigate these phenomena based on the derivation, justification and analysis of relevant asymptotic models. This approach allows us to investigate more complex phenomena that are not dealt with in the physics literature such as the influence of a variable bottom or the generalization of the Proudman resonance in deeper waters. First, we prove a local well-posedness of the water waves equations with a moving bottom and a non constant pressure at the surface taking into account the dependence of small physical parameters and we show that these equations are a Hamiltonian system (which extend the result of Zakharov [33]). Then, we justify some linear asymptotic models in order to study the Proudman resonance and submarine landslide tsunamis; we study the linear water waves equations and dispersion estimates allow us to investigate the amplitude of the sea level. To complete these asymptotic models, we add some numerical simulations.

description: The nature of black hole jets at the lowest detectable luminosities remains an open question, largely due to a dearth of observational constraints. Here, we present a new, nearly-simultaneous broadband spectrum of the black hole X-ray binary (BHXB) XTE J1118+480 at an extremely low Eddington ratio (L_x~1e-8.5 L_Edd). Our new spectral energy distribution (SED) includes the radio, near-infrared, optical, ultraviolet, and X-ray wavebands. XTE J1118 is now the second BHXB at such a low Eddington ratio with a well-sampled SED, providing new constraints on highly sub-Eddington accretion flows and jets, and opening the door for comparison studies. We apply a multi-zone jet model to the new broadband SED, and we compare our results to previous fits to the same source using the same model at 4-5 decades higher luminosity. We find that after a BHXB transitions to the so-called quiescent spectral state, the jet base becomes more compact (by up to an order of magnitude) and slightly cooler (by at least a factor of two). Our preferred model fit indicates that jet particle acceleration is weaker after the transition into quiescence. That is, accelerated non-thermal particles no longer reach high enough Lorentz factors to contribute significant amounts of synchrotron X-ray emission. Instead, the X-ray waveband is dominated by synchrotron self-Compton emission from a population of mildly relativistic electrons with a quasi-thermal velocity distribution associated with the jet base. The corresponding (thermal) synchrotron component emits primarily in the infrared through ultraviolet wavebands. Our results on XTE J1118 are consistent with broadband modeling for A0620-00 and for Sgr A*. The above could therefore represent a canonical baseline geometry for accreting black holes in quiescence. We conclude with suggestions for future studies to further investigate the above scenario.

description: Among messengers used in indirect searches for dark matter (DM), neutrinos are special as they are neutral, light, and seldom interact. These unique properties give them advantages in astrophysical studies: they are advantageous over cosmic rays as they are able to point back to their sources and unlike gamma rays can exit environments of large matter and radiation densities. I will present a new flexible Monte Carlo simulation tool to generate neutrino fluxes at detectors searching for signatures of DM annihilation and decay. The expected flux from galactic and extragalactic sources will be discussed, as well as the Earth and the Sun. In the latter case, we will also consider the possibility of a secluded dark matter sector which introduces a long-lived mediator.

description: One of the most important unresolved issues in gamma-ray burst physics is the origin of the prompt gamma-ray spectrum. Its general non-thermal character and the softness in the X-ray band remain unexplained. We tackle these issues by performing Monte Carlo simulations of radiation-matter interactions in a scattering dominated photon-lepton plasma. The plasma -- initially in equilibrium -- is driven to non-equilibrium conditions by a sudden energy injection in the lepton population, mimicking the effect of a shock wave or the dissipation of magnetic energy. Equilibrium restoration occurs due to energy exchange between the photons and leptons. While the initial and final equilibrium spectra are thermal, the transitional photon spectra are characterized by non-thermal features such as power-law tails, high energy bumps, and multiple components. Such non-thermal features are observed at infinity if the dissipation occurs at small to moderate optical depths, and the spectrum is released before thermalization is complete. We model the synthetic spectra with a Band function and show that the resulting spectral parameters are similar to observations for a frequency range of 2-3 orders of magnitude around the peak. In addition, our model predicts correlations between the low-frequency photon index and the peak frequency as well as between the low- and high-frequency indices. We explore baryon and pair dominated fireballs and reach the conclusion that baryonic fireballs are a better model for explaining the observed features of gamma-ray burst spectra.
