description: In this work, we present a leptonic, time-dependent model of pulsar wind nebulae (PWNe). The model seeks a solution for the lepton distribution function considering the full time-energy dependent diffusion-loss equation. The time-dependent lepton population is balanced by injection, energy losses, and escape. We include synchrotron, inverse Compton (IC, with the cosmic-microwave background as well as with IR/optical photon fields), self-synchrotron Compton (SSC), and bremsstrahlung processes, all devoid of any radiative approximations. With this model in place we focus on the Crab nebula as an example and present its time dependent evolution. Afterwards, we analyze the impact of different approximations made at the level of the diffusion-loss equation, as can be found in the literature. Whereas previous models ignored the escape term, e.g., with the diffusion-loss equation becoming advective, others approximated the losses as catastrophic, so that the equation has only time derivatives. Additional approximations are also described and computed. We show which is the impact of these approaches in the determination of the PWN evolution. In particular, we find the time-dependent deviation of the multi-wavelength spectrum and the best-fit parameters obtained with the complete and the approximate models.

Evaluation of the value of activity-based token reinforcement
Creators: name: Massaro, Isabella
Publisher: name: No Publisher Supplied
Year: 2022

description: In ABA, tokens are a conditioned stimulus that can be used to reinforce behavior when delivered following the response (Hackenberg, 2009). Traditional tokens can take many different forms, including pennies, stickers, or check marks. However, for some learners, these tokens may have no reinforcing effect, and the resulting token economy may have a weak reinforcing effect. Very little research has been done examining the different types of tokens that are used in a token economy. The present study sought to determine if items from a learner’s preferred activities could be used as tokens and if they are more reinforcing than the traditional token. Study 1 replicated Fiske et al.’s (2020) use of a multiple-schedule reinforcer assessment to assess the value of traditional and activity-based tokens. Study 2 replicated Charlop-Christy and Haymes (1998) method to evaluate whether the use of activity tokens led to more accurate responding in an academic task than the traditional tokens. One student participated in both studies. The results of Study 1 indicate that the student engaged in more responses when an activity token with backup reinforcement was delivered as a consequence, compared to when the traditional token with backup reinforcement was used. However, no difference in responding was observed when the tokens were presented as a consequence without backup reinforcement. In Study 2, the learner engaged in more accurate responding on an academic task when activity tokens were delivered than when traditional tokens were delivered. Overall, the results of this study demonstrate that the type of token being used for a learner can affect performance and activity-based token economies can be an effective system of reinforcement.

description: Nonlocal PNJL models allow for a detailed description of chiral quark dynamics with running quark masses and wave function renormalization in accordance with lattice QCD (LQCD) in vacuum. Their generalization to finite temperature T and chemical potential μ allows to reproduce the μ-dependence of the pseudocritical temperature from LQCD when a nonvanishing vector meson coupling is adjusted. This restricts the region for the critical endpoint in the QCD phase diagram and stiffens the quark matter equation of state (EoS). It is demonstrated that the construction of a hybrid EoS for compact star applications within a two-phase approach employing the nonlocal PNJL EoS and an advanced hadronic EoS leads to the masquerade problem. A density dependence of the vector meson coupling is suggested as a possible solution which can be adjusted in a suitable way to describe hybrid stars with a maximum mass in excess of 2 M_sun with a possible early onset of quark deconfinement even in the cores of typical (M ~ 1.4 M_sun) neutron stars.

description: The recently discovered transiting super-Earth LP 890-9 c is potentially one of the best rocky exoplanets for atmospheric characterization. Orbiting an ultracool M-dwarf at the inner edge of the habitable zone, LP 890-9 c offers a new opportunity to study the climate of rocky planets at the inner edge of the habitable zone. We investigate the molecular detectability with simulated JWST transmission spectra for five potential atmospheres of LP 890-9 c. We find that a small three-transit JWST program can infer evidence of H2O (at 3$σ$ confidence) for a full runaway greenhouse scenario. Alternatively, CO2-dominated atmospheres resembling Venus without high-altitude terminator clouds can be identified with eight transits. However, these predictions could be complicated by the impact of clouds and/or unocculted starspots. Nevertheless, JWST observations of LP 890-9 c could provide critical insights and potentially distinguish between models of rocky planets at the inner edge of the habitable zone.

description: We present SCUBA-2 850um observations for 7 very low mass stars (VLMS) and brown dwarfs (BDs): 3 in Taurus, 4 in the TWA, and all classical T Tauri (cTT) analogs. We detect 2 of the 3 Taurus disks, but none of the TWA ones. Our 3sigma limits correspond to a dust mass of 1.2 MEarth in Taurus and a mere 0.2 MEarth in the TWA (3--10x deeper than previous work). We combine our data with other sub-mm/mm surveys of Taurus, rho Oph and the TWA to investigate trends in disk mass and grain growth during the cTT phase. We find : (1) The minimum disk outer radius required to explain the upper envelope of sub-mm/mm fluxes is 100 AU for intermediate-mass stars, solar-types and VLMS, and 20 AU for BDs. (2) While the upper envelope of disk masses increases with Mstar from BDs to VLMS to solar-types, no increase is seen from solar-type to intermediate-mass stars. We propose this is due to enhanced photoevaporation around intermediate masses. (3) Many disks around Taurus and rho Oph intermediate-mass and solar-type stars evince an opacity index beta of 0--1, indicating large grains. Of the only four VLMS/BDs in these regions with multi-wavelength data, three are consistent with large grains, though optically thick disks are not ruled out. (4) For the TWA VLMS (TWA 30A, B), combining our fluxes with Mdot and ages suggests substantial grain growth by 10 Myr. The degree of grain growth in the TWA BDs (2M1207A, SSPM1102) remains largely unknown. (5) A Bayesian analysis shows that mean(log[Mdisk/Mstar]) = -2.4, roughly constant all the way from intermediate-mass stars to VLMS/BDs, and (6) the disk mass in close solar-type Taurus binaries is significantly lower than in singles (by a factor of 10), while that in wide solar-type Taurus binaries is closer to that in singles (lower by a factor of 3). (7) We discuss the implications for planet formation, and for the dependence of Mdot on Mstar.

Multivariate Bayesian Logistic Regression for Analysis of Clinical Study Safety Issues
Creators: name: DuMouchel, William
Publisher: name: arXiv
Year: 2012
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: This paper describes a method for a model-based analysis of clinical safety data called multivariate Bayesian logistic regression (MBLR). Parallel logistic regression models are fit to a set of medically related issues, or response variables, and MBLR allows information from the different issues to "borrow strength" from each other. The method is especially suited to sparse response data, as often occurs when fine-grained adverse events are collected from subjects in studies sized more for efficacy than for safety investigations. A combined analysis of data from multiple studies can be performed and the method enables a search for vulnerable subgroups based on the covariates in the regression model. An example involving 10 medically related issues from a pool of 8 studies is presented, as well as simulations showing distributional properties of the method.

Semi-blind Source Separation via Sparse Representations and Online Dictionary Learning

description: This work examines a semi-blind single-channel source separation problem. Our specific aim is to separate one source whose local structure is approximately known, from another a priori unspecified background source, given only a single linear combination of the two sources. We propose a separation technique based on local sparse approximations along the lines of recent efforts in sparse representations and dictionary learning. A key feature of our procedure is the online learning of dictionaries (using only the data itself) to sparsely model the background source, which facilitates its separation from the partially-known source. Our approach is applicable to source separation problems in various application domains; here, we demonstrate the performance of our proposed approach via simulation on a stylized audio source separation task.

description: Outflows play a major role in the evolution of galaxies and are said to be ubiquitous within the Active Galactic Nuclei (AGNs) population. However, we are far from having a complete picture of their properties, specially considering their impact on the evolution of Low-Ionisation Nuclear Emission-line Regions (LINERs).
 Although resolved kinematic information has proven to be crucial for the fully characterisation of these phenomena, imaging techniques can be really useful for the systematic search of outflow candidates.
 We have obtained narrow-band optical Hα images with ALFOSC/NOT and retrieved soft-X ray and narrow-band Halpha images from Chandra and HST archives, respectively, for a total of 70 LINERs. We classified the ionised gas morphologies based on the extension and overall shape of the Halpha emission.
 We find that the soft X-ray and ionised gas emission coincide in the great majority of LINERs (60%), as previously seen for Seyferts (Bianchi et al. 2006), suggesting a common origin for both emissions.
 Our results show that approximately one third of the targets present extended, filamentary emission with a distinguishable bubble-shaped morphology. When combining NOT imaging data and spectroscopic data from the current literature we find that outflows are present in 48% of the nearby LINERs.
Enhanced One-Loop Corrections to WIMP Annihilation and their Thermal Relic Density in the Coannihilation Region

description: We consider quantum corrections to co-annihilation processes of Weakly Interacting Massive Particles (WIMPs) due to the exchange of light bosons in the initial state ("Sommerfeld corrections"). We work at one-loop level, i.e. we assume that these corrections can be treated perturbatively. Co-annihilation is important if there is at least one additional new particle with mass close to the lightest WIMP, which is a Dark Matter candidate. In this case the exchange of a (relatively light) boson in the initial state can change the identity of the annihilating particles. The corrections we are interested in factorize, as in the case of WIMP self-annihilation treated previously, but they can mix different tree-level amplitudes. Moreover, even small mass splittings between the external particles and those in the loop can change the relevant loop functions significantly. We find exact analytical expressions for these functions, and illustrate the effects by considering the cases of wino- or higgsino-like neutralinos as examples.

Kohlendioxidentnahme

description: Dieses Policy Brief von CDRterra stellt die Grundlagen von Kohlendioxidentnahme (Carbon Dioxide Removal, CDR) anhand von fünf Kernaussagen vor:1. Das Ziel der Treibhausgasneutralität bis 2045 verlangt schnelle, drastische und umfassende Emissionsreduktionen – und das sofort. Nach Aussage des Weltklimarates setzt ein Einhalten des 1,5-Grad Ziels zum Ende dieses Jahrhunderts voraus, dass die Menschheit ihre Treibhausgasemissionen bis zum Jahr 2035 um mindestens 60 Prozent im Vergleich zu 2019 reduziert – und selbst dann ist ein kurzfristiges Überschreiten der 1,5-Grad-Marke nicht ausgeschlossen. 2. Restemissionen werden bei Aktivitäten entstehen, die von der Gesellschaft als notwendig erachtet werden, deren Treibhausgasausstoß sich jedoch technisch gar nicht oder aber nur zu enorm hohen Kosten vermeiden lassen wird.Eine einheitliche Definition des Begriffs „Restemissionen” fehlt bislang. Es ist zudem gesellschaftlich auch noch nicht ausgehandelt, welche Aktivitäten künftig Restemissionen verursachen dürfen und welche nicht. Aktuell scheint es, als würde man bestimmten Akteuren aus politischen Gründen „schwer vermeidbare Emissionen” zugestehen, obwohl diese Emissionen tatsächlich technisch und günstig zu vermeiden wären. 3. Wer Treibhausgasemissionen vermeidet, schützt das Klima am effizientesten. Restemissionen können jedoch nur durch eine aktive Kohlendioxidentnahme ausgeglichen werden.Restemissionen lassen sich nur kompensieren, indem Kohlendioxid aus der Atmosphäre entnommen und anschließend dauerhaft von der Atmosphäre ferngehalten wird. 4. Jederzeit klar zwischen Emissionsvermeidung und einer tatsächlichen Kohlendioxidentnahme zu unterscheiden, ist unerlässlich.Wird an dieser Stelle nicht jederzeit klar getrennt, sind unter anderem Schwierigkeiten bei der Bilanzierung und Regulierung vorprogrammiert. Im Zuge dessen wäre auch das Ziel der Treibhausgasneutralität in Gefahr. 5. Die Entnahme und Speicherung von Kohlendioxid müssen nachweislich erfolgen und mit einheitlichen Methoden überwacht und dokumentiert werden – unter Umständen für sehr lange Zeit.Dafür bedarf es klarer und einheitlicher Berichts- und Dokumentationsregeln sowie verlässlicher Mess- und Beobachtungsverfahren für Entnahme- und Speicherstätten.

description: Mercury, the innermost planet, formed under highly reduced conditions, based mainly on surface Fe, S, and Si abundances determined from MESSENGER mission data. The minor element Cr may serve as an independent oxybarometer, but only very limited Cr data have been previously reported for Mercury. We report Cr/Si abundances across Mercury's surface based on MESSENGER X-Ray Spectrometer data throughout the spacecraft's orbital mission. The heterogeneous Cr/Si ratio ranges from 0.0015 in the Caloris Basin to 0.0054 within the high-magnesium region, with an average southern hemisphere value of 0.0008 (corresponding to about 200 ppm Cr). Absolute Cr/Si values have systematic uncertainty of at least 30%, but relative variations are more robust. By combining experimental Cr partitioning data along with planetary differentiation modeling, we find that if Mercury formed with bulk chondritic Cr/Al, Cr must be present in the planet's core and differentiation must have occurred at log fO2 in the range of IW-6.5 to IW-2.5 in the absence of sulfides in its interior, and a range of IW-5.5 to IW-2 with an FeS layer at the core-mantle boundary. Models with large fractions of Mg-Ca-rich sulfides in Mercury's interior are more compatible with moderately reducing conditions (IW-5.5 to IW-4) owing to the instability of Mg-Ca-rich sulfides at elevated fO2. These results indicate that if Mercury differentiated at a log fO2 lower than IW-5.5, the presence of sulfides whether in the form of a FeS layer at the top of the core or Mg-Ca-rich sulfides within the mantle would be unlikely.

description: Many applications generate and consume temporal data and retrieval of time series is a key processing step in many application domains. Dynamic time warping (DTW) distance between time series of size N and M is computed relying on a dynamic programming approach which creates and fills an NxM grid to search for an optimal warp path. Since this can be costly, various heuristics have been proposed to cut away the potentially unproductive portions of the DTW grid. In this paper, we argue that time series often carry structural features that can be used for identifying locally relevant constraints to eliminate redundant work. Relying on this observation, we propose salient feature based sDTW algorithms which first identify robust salient features in the given time series and then find a consistent alignment of these to establish the boundaries for the warp path search. More specifically, we propose alternative fixed core&adaptive width, adaptive core&fixed width, and adaptive core&adaptive width strategies which enforce different constraints reflecting the high level structural characteristics of the series in the data set. Experiment results show that the proposed sDTW algorithms help achieve much higher accuracy in DTWcomputation and time series retrieval than fixed core & fixed width algorithms that do not leverage local features of the given time series.

description: We experimentally investigate the symmetry in the Hidden Order (HO) phase of intermetallic URu2Si2 by mapping the lattice and magnetic excitations via inelastic neutron and x-ray scattering measurements in the HO and high-temperature paramagnetic phases. At all temperatures the excitations respect the zone edges of the body-centered tetragonal paramagnetic phase, showing no signs of reduced spatial symmetry, even in the HO phase. The magnetic excitations originate from transitions between hybridized bands and track the Fermi surface, whose feature are corroborated by the phonon measurements. Due to a large hybridization energy scale, a full uranium moment persists in the HO phase, consistent with a lack of observed crystal-field-split states. Our results are inconsistent with local order parameter models and the behavior of typical density waves. We suggest that an order parameter that does not break spatial symmetry would naturally explain these characteristics.
description: 16 pages, 13 figures The scope of this work was expanded to include much more magnetic neutron scattering as well as inelastic x-ray scattering. The modes originally identified as soft phonons are magnetic. Many of the figures had their quality reduced in order to fit the arxiv file size limits.

description: We add a periodic potential to the simplest gravitational model of a superconductor and compute the optical conductivity. In addition to a superfluid component, we find a normal component that has Drude behavior at low frequency followed by a power law fall-off. Both the exponent and coefficient of the power law are temperature independent and agree with earlier results computed above $T_c$. These results are in striking agreement with measurements on some cuprates. We also find a gap $Δ= 4.0\ T_c$, a rapidly decreasing scattering rate, and "missing spectral weight" at low frequency, all of which also agree with experiments.

description: We present a multi-wavelength analysis of gamma-ray burst GRB 090727, for which optical emission was detected during the prompt gamma-ray emission by the 2-m autonomous robotic Liverpool Telescope and subsequently monitored for a further two days with the Liverpool and Faulkes telescopes. Within the context of the standard fireball model, we rule out a reverse shock origin for the early time optical emission in GRB 090727 and instead conclude that the early time optical flash likely corresponds to emission from an internal dissipation processes. Putting GRB 090727 into a broader observational and theoretical context, we build a sample of 36 gamma-ray bursts (GRBs) with contemporaneous early time optical and gamma-ray detections. From these GRBs, we extract a sub-sample of 18 GRBs, which show optical peaks during prompt gamma-ray emission, and perform detailed temporal and spectral analysis in gamma-ray, X-ray, and optical bands. We find that in most cases early time optical emission shows sharp and steep behaviour, and notice a rich diversity of spectral properties. Using a simple internal shock dissipation model, we show that the emission during prompt GRB phase can occur at very different frequencies via synchrotron radiation. Based on the results obtained from observations and simulation, we conclude that the standard external shock interpretation for early time optical emission is disfavoured in most cases due to sharp peaks ($Δt/t < 1$) and steep rise/decay indices, and that internal dissipation can explain the properties of GRBs with optical peaks during gamma-ray emission.

description: Spider monkeys (genus Ateles) have a prehensile tail that functions as a flexible, multipurpose fifth limb, enabling them to navigate complex terrains, grasp objects of various sizes, and swing between supports. Inspired by the spider monkey tail, we present a life size hybrid soft-rigid continuum robot designed to imitate the function of the tail. Our planar design has a rigid skeleton with soft elements at its joints that achieve decreasing stiffness along its length. Five manually-operated wires along this central structure control the motion of the tail to form a variety of possible shapes in the 2D plane. Our design also includes a skin-like silicone and fabric tail pad that moves with the tail's tip and assists with object grasping. We quantify the force required to pull various objects out of the robot's grasp and demonstrate that this force increases with the object diameter and the number of edges in a polygonal object. We demonstrate the robot's ability to grasp, move, and release objects of various diameters, as well as to navigate around obstacles, and to retrieve an object after passing under a low passageway.

title: How effective is the Climate Justice Movement in sub-Saharan Africa?
Creators: name: Aliyu, Zainab Ojone

description: Climate change (CC) remains one of the most pressing challenges globally and particularly for sub-Saharan Africa (SSA) which lies in the frontline of the catastrophic impacts of CC. Yet, global progress towards urgent, ambitious, and equitable climate action (CA) remains slow. And while this holds devastating consequences for the people of SSA, and thus places the burden of demanding urgent and just climate action on them, it is also the case that only very limited research has been conducted until now on the Climate Justice movement (CJM) in SSA. Using the Pan African Climate Justice Alliance (PACJA) as a case study and drawing on 42 key informant interviews and over 150 hours of participant observation carried out over 16 months (August 2018 to December, 2019) at six different study sites, this thesis investigates the effectiveness of the CJM in SSA in their demand for climate justice (CJ). Specifically, it analyses 1) the Movement’s effectiveness in three domains: (a) Institutional and Governance strengthening, (b) Public awareness, engagement and mobilisation and (c) Policy influence; and 2) the factors or structural conditions) that inhibit their effectiveness. Building on the extant studies and literatures on CJ, social movements and organisational effectiveness, this thesis develops an analytical framework that underpins the analysis and understanding of the CJM’s effectiveness. It argues that PACJA is moderately effective in its progress towards achieving its CJ objectives in the three categories that were analysed. It identifies four overlapping factors that currently limit the effectiveness of the Movement: 1) managing complex institutional dynamics, 2) underdeveloped mechanisms, strategies and tactics, 3) limited technical, financial, and political resources, and 4) a complex external socio-political environment. Thus, to be effective, the CJM must (i) harmonise and align their CJ framings and narratives in ways that connect and inspire the public for increased participation in the CC governance processes at different levels, (ii) identify and solidify a coherent set of strategies and tactics, (iii) explore more localised fundraising opportunities and, (iv) build enabling socio-political conditions that will support mass mobilisation for urgent climate actions in SSA.

description: This paper considers the nonparametric regression model with an additive error that is dependent on the explanatory variables. As is common in empirical studies in epidemiology and economics, it also supposes that valid instrumental variables are observed. A classical example in microeconomics considers the consumer demand function as a function of the price of goods and the income, both variables often considered as endogenous. In this framework, the economic theory also imposes shape restrictions on the demand function, like integrability conditions. Motivated by this illustration in microeconomics, we study an estimator of a nonparametric constrained regression function using instrumental variables by means of Tikhonov regularization. We derive rates of convergence for the regularized model both in a deterministic and stochastic setting under the assumption that the true regression function satisfies a projected source condition including, because of the non-convexity of the imposed constraints, an additional smallness condition.

description: Today's scientists are quickly moving from in vitro to in silico experimentation: they no longer analyze natural phenomena in a petri dish, but instead they build models and simulate them. Managing and analyzing the massive amounts of data involved in simulations is a major task. Yet, they lack the tools to efficiently work with data of this size. One problem many scientists share is the analysis of the massive spatial models they build. For several types of analysis they need to interactively follow the structures in the spatial model, e.g., the arterial tree, neuron fibers, etc., and issue range queries along the way. Each query takes long to execute, and the total time for executing a sequence of queries significantly delays data analysis. Prefetching the spatial data reduces the response time considerably, but known approaches do not prefetch with high accuracy. We develop SCOUT, a structure-aware method for prefetching data along interactive spatial query sequences. SCOUT uses an approximate graph model of the structures involved in past queries and attempts to identify what particular structure the user follows. Our experiments with neuroscience data show that SCOUT prefetches with an accuracy from 71% to 92%, which translates to a speedup of 4x-15x. SCOUT also improves the prefetching accuracy on datasets from other scientific domains, such as medicine and biology.

Outside the Sandbox: A Study of Input/Output Methods in Java

description: Programming languages often demarcate the internal sandbox, consisting of entities such as objects and variables, from the outside world, e.g., files or network. Although communication with the external world poses fundamental challenges for live programming, reversible debugging, testing, and program analysis in general, studies about this phenomenon are rare. In this paper, we present a preliminary empirical study about the prevalence of input/output (I/O) method usage in Java. We manually categorized 1435 native methods in a Java Standard Edition distribution into non-I/O and I/O-related methods, which were further classified into areas such as desktop or file-related ones. According to the static analysis of a call graph for 798 projects, about 57% of methods potentially call I/O natives. The results of dynamic analysis on 16 benchmarks showed that 21% of the executed methods directly or indirectly called an I/O native. We conclude that neglecting I/O is not a viable option for tool designers and suggest the integration of I/O-related metadata with source code to facilitate their querying.

description: The basics of precanonical quantization and its relation to the functional Schrödinger picture in QFT are briefly outlined. The approach is applied to quantization of Einstein's gravity in vielbein and spin connection variables and leads to a quantum dynamics described by the covariant Schrödinger equation for the transition amplitudes on the bundle of spin connection coefficients over the space-time, that yields a novel quantum description of space-time geometry. A toy model of precanonical quantum cosmology based on the example of flat FLRW universe is considered.

description: The soil algal strain Parachlorella kessleri TY possesses unique metabolic capacity. However, systemic information relevant to the molecular regulation of its metabolic processes under stress is unavailable. This study investigated the performance of P. kessleri under nitrogen deficiency (N–) and normal nitrogen (N+) conditions. The results showed that P. kessleri accumulated high amounts of carbohydrates and lipids under N– and concomitantly decreased its biomass yield, chlorophyll content, photochemical efficiency of photosystem II (Fv/Fm), and total protein levels. Transcriptome sequencing to identify the molecular responses of the microalgae under N– resulted in a total of 112 811 assembled transcripts annotated and classified into different biological categories and pathways based on the results of BLAST against diverse databases. An in-depth gene expression profiling analysis showed that many differentially expressed genes in P. kessleri under N– versus N+ conditions are involved in lipid metabolism. The transcript abundance of the genes that encode enzymes involved in fatty acid and unsaturated fatty acid biosynthesis (such as accC, fabF, fabH, FAD2 and SCD) were significantly increased. However, a set of genes that encode enzymes involved in lipid degradation decreased their expression under N–. This difference highlights the coordinated regulation of the lipid metabolism at the transcription level. The de novo transcriptome assembly lays a foundation for the genetic improvement of the lipid content and composition of P. kessleri in the future.

description: A solar flare is composed of impulsive energy release events by magnetic reconnection, which forms and heats flare loops. Recent studies have revealed a two-phase evolution pattern of UV 1600Å emission at the feet of these loops: a rapid pulse lasting for a few seconds to a few minutes, followed by a gradual decay on timescales of a few tens of minutes. Multiple band EUV observations by AIA further reveal very similar signatures. These two phases represent different but related signatures of an impulsive energy release in the corona. The rapid pulse is an immediate response of the lower atmosphere to an intense thermal conduction flux resulting from the sudden heating of the corona to high temperatures (we rule out energetic particles due to a lack of significant hard X-ray emission). The gradual phase is associated with the cooling of hot plasma that has been evaporated into the corona. The observed footpoint emission is again powered by thermal conduction (and enthalpy), but now during a period when approximate steady state conditions are established in the loop. UV and EUV light curves of individual pixels may therefore be separated into contributions from two distinct physical mechanisms to shed light on the nature of energy transport in a flare. We demonstrate this technique using coordinated, spatially resolved observations of UV and EUV emission from the footpoints of a C3.2 thermal flare.
