description: Food tourism is an activity that can be promoted by destination marketers. The aims of this research are to provide a holistic examination of domestic tourists’ food experience in China, and to evaluate the potential of food tourism in promoting Chinese regions from the demand side. It has four specific research objectives, including (1) examining the food experience of domestic tourists at three different travel stages in China, (2) assessing the relationships between the food experience of tourists and their demographic profiles, (3) developing a structural model addressing the potential relationships between tourists’ food experience and loyalty intentions toward Chinese destinations, and (4) providing recommendations for marketers to achieve successful destination promotion through food tourism. In order to achieve the research aims and objectives, with the development of a structural theoretical model, a quantitative research design was employed in the study. Data was specifically collected from a sample of 1702 domestic tourists at ten representative destinations in Mainland China. The findings of this study revealed that: firstly, food is, overall, of great significance to Chinese domestic tourists; however, it plays a varying role in domestic tourists’ experiences at different travel stages in China. Secondly, demographic factors such as gender and age have influences on the food experience of Chinese domestic tourists, while educational level has been revealed to be of little influence. Thirdly, tourists’ food satisfaction and food-related behavioural intentions were in direct and positive correlation to tourists’ destination loyalty intentions. The findings highlighted the contribution of local food at a destination level in the context of China, and signified the great potential for destinations to utilise food tourism to attract and retain tourists. Moreover, given the interrelationships shown between the underlying factors of tourists’ food experience and tourists’ destination loyalty intentions, it is noted that tourists’ food experience is a complex multi-phase model among which different phases interrelate with each other exerting an influence on tourists’ loyalty intentions to specific destinations in China. Lastly, based on these findings, both theoretical and practical implications were derived. In particular, practical recommendations have been provided to marketers on how to effectively utilise food tourism to achieve successful destination promotion in China.

description: Following on from the successful pilot study funded by Historic Scotland which assessed the previous work and analyses carried out on Scottish White Gritty Ware pottery, a major investigation of the Scottish White Gritty Ware industry was initiated by Glasgow University Archaeological Research Division and funded by Historic Scotland. The project set out to examine the range and type of vessels, the production areas and chemical composition of the clays used in the production of Scottish White Gritty Ware. The chemical and petrographic analyses aimed to identify the source or sources of the pottery and its distribution within Scotland. Over six hundred sherds of pottery from over forty Scottish archaeological sites were evaluated by chemical analysis using ICP, combined with the petrographic examination of a selection of thin sections. Also undertaken as part of the project were the construction of a Scottish White Gritty Ware vessel typology, a limited programme of clay prospection, a review of past scientific work, glaze analysis, chemical comparisons with English and Continental material and a geophysical survey of the Scottish White Gritty Ware kiln site at Colstoun in East Lothian. The petrographic analyses were carried out on the existing thin section collection housed in the National Museum of Scotland and newly prepared examples from sherds especially selected for the study. The results of the analyses have pointed to the production of White Gritty ware in several areas of Scotland from the Scottish Borders to the Moray Firth and have identified those geographic areas that require further research and excavation. This study has put together the largest and one of the most significant datasets for any Medieval European ceramic industry and has created a major platform for any future work on Scottish ceramics.

description: The rare top decay t-> c l+l-, which involves flavor violation, is studied as a possible probe of new physics. This decay is analyzed with the simplest Standard Model extensions with additional gauge symmetry formalism. The considered extension is the Left-Right Symmetric Model, including a new neutral gauge boson Z' that allows to obtain the decay at tree level through Flavor Changing Neutral Currents (FCNC) couplings. The neutral gauge boson couplings are considered diagonal but family non-universal in order to induce these FCNC. We find the $BR(t-> c l+l-)~10^{-13} for a range 1 TeV < M_{Z'} < 3 TeV.

HIV-positive persons--Care

description: Background
The well-documented shortages of health care workers (HCWs) in sub-Saharan Africa are further intensified by the increased human resource needs of expanding HIV treatment programs. Burnout is a syndrome of emotional exhaustion (EE), depersonalization (DP), and a sense of low personal accomplishment (PA). HCWs’ burnout can negatively impact the delivery of health services. Our main objective was to examine the prevalence of burnout amongst HCWs in Malawi and explore its relationship to self-reported suboptimal patient care.

Methods
A cross-sectional study among HCWs providing HIV care in 89 facilities, across eight districts in Malawi was conducted. Burnout was measured using the Maslach Burnout Inventory defined as scores in the mid-high range on the EE or DP subscales. Nine questions adapted for this study assessed self-reported suboptimal patient care. Surveys were administered anonymously and included socio-demographic and work-related questions. Validated questionnaires assessed depression and at-risk alcohol use. Chi-square test or two-sample t-test was used to explore associations between variables and self-reported suboptimal patient care. Bivariate analyses identified candidate variables (p < 0.2). Final regression models included variables with significant main effects.

Results
Of 520 HCWs, 62% met criteria for burnout. In the three dimensions of burnout, 55% reported moderate-high EE, 31% moderate-high DP, and 46% low-moderate PA. The majority (89%) reported engaging in suboptimal patient care/attitudes including making mistakes in treatment not due to lack of knowledge/experience (52%), shouting at patients (45%), and not performing diagnostic tests due to a desire to finish quickly (35%). In multivariate analysis, only burnout remained associated with self-reported suboptimal patient care (OR 3.22, [CI 2.11 to 4.90]; p<0.0001).

Conclusion
Burnout was common among HCWs providing HIV care and was associated with self-reported suboptimal patient care practices/attitudes. Research is needed to understand factors that contribute to and protect against burnout and that inform the development of strategies to reduce burnout.
An unified resolution to B anomalies with lepton mixing

Publisher: name: Zenodo
Year: 2019

description: In view of several hints of lepton non universality, observed in B meson decays, we find that with a minimal modification to the SM in terms of an effective theory, the charged as well as neutral current anomalies can well be explained by introducing just two new parameters. This class of operators predict some interesting signatures both in the context of B decays as well as high-energy collisions.

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 28, 1-16
description: Until the beginning of the 1980s only two pottery kilns were known from the Middle Ages in the Danish area. Both kilns were found on Zealand at the localities of Farum Lillevang and Faurholm. Not until 1983 did new finds appear. In the course of several months three new pottery kilns were found with accompanying discarded and misfired pottery. The first of these kilns was found on the western edge of the village of Hellum in eastern Himmerland. Only a few months later the remains of another kiln appeared at the village of Kragelund about twenty kilometers north of Silkeborg, and almost at the same time more pottery and kilns came to light near the village of Barmer in Himmerland. The three new kilns were not only widely different in construction but also different from those already known. This gave rise to the establishment of a research and publishing project that included an analysis of the kilns as well as the preserved pottery, the realization of a series of experimental archaeological experiments, and the collection of comparative archaeological material and selected parallel ethnological and ethnographic material.

Suicide in mass media

description: Investigating suicides following the death of Robin Williams, a beloved actor and comedian, on August 11th, 2014, we used time-series analysis to estimate the expected number of suicides during the months following Williams’ death. Monthly suicide count data in the US (1999–2015) were from the Centers for Disease Control and Prevention Wide-ranging ONline Data for Epidemiologic Research (CDC WONDER). Expected suicides were calculated using a seasonal autoregressive integrated moving averages model to account for both the seasonal patterns and autoregression. Time-series models indicated that we would expect 16,849 suicides from August to December 2014; however, we observed 18,690 suicides in that period, suggesting an excess of 1,841 cases (9.85% increase). Although excess suicides were observed across gender and age groups, males and persons aged 30–44 had the greatest increase in excess suicide events. This study documents associations between Robin Williams’ death and suicide deaths in the population thereafter.

description: Two-pulse correlation is employed to investigate the temporal dynamics of both two-photon photoluminescence (2PPL) and four-photon photoluminescence (4PPL) in resonant and nonresonant nanoantennas excited at a wavelength of 800 nm. Our data are consistent with the same two-step model being the cause of both 4PPL and 2PPL, implying that the first excitation step in 4PPL is a three-photon sp->sp direct interband transition. Considering energy and parity conservation, we also explain why 4PPL behavior is favored over three-and five-photon photoluminescence in the power range below the damage threshold of our antennas. Since sizeable 4PPL requires larger peak intensities of the local field, we are able to select either 2PPL or 4PPL in the same gold nanoantennas by choosing a suitable laser pulse duration. We thus provide a first consistent model for the understanding of multiphoton photoluminescence generation in gold nanoantennas, opening new perspectives for applications ranging from the characterization of plasmonic resonances to biomedical imaging.

description: Medieval Ceramics: Journal of the Medieval Ceramics Research Group, 28, 115-121
description: In this paper I have tried to demonstrate that pottery from consumer assemblages can be used to develop models which attempt to explain the mechanics of change and the cultural and social factors affecting consumption. The paper is in three parts. The first provides a brief overview of the consumption of pottery as observed in assemblages from consumer sites in Worcestershire dating to between c AD900 and AD1600. This is intended to provide a context for the second and third parts which focus on factors which may have affected the development of this pattern of consumption. The first factor is the greatly increased mortality rate of the 14th century, and how this could have affected the economic situation and the aspirations of both producer and consumer. The second factor is how ceramics may, or may not, have been seen as objects of desire by English medieval society.

description: Physical activity is a cornerstone of secondary prevention after acute coronary syndromes (ACS). Guidelines strongly recommend that post-ACS patients achieve ≥30 min of moderate aerobic activity such as brisk walking on at least 5 days per week within 2 weeks of discharge (1). Yet, little is known about the extent to which post-ACS patients are meeting physical activity guidelines. Prior studies assessing physical activity after ACS were limited by reliance on self-reports (2). The purpose of this study was to use an objective measure of physical activity to describe the proportion of ACS patients following physical activity recommendations in the high-risk post-discharge period.

Between 2009 and 2012, we enrolled patients hospitalized for myocardial infarction (MI) or unstable angina into the PULSE (Prescription Use, Lifestyle, and Stress Evaluation) study. Some patients participated in an ancillary study in which they were provided with an Actical accelerometer (Philips Respironics, Bend, Oregon) at or soon after discharge (3). Patients were asked to continuously wear the device on their nondominant wrist and to return the device 1 month later. All patients provided informed consent. The institutional review board of Columbia University Medical Center approved the study.

description: We present a systematic analysis of the X-ray spectra of NGC 1313 X-1 and NGC 1313 X-2, using three years of XMM-Newton observations. We fitted the continuum with a Comptonization model plus a multicolor blackbody disc, that describes the effects of an accretion disc plus a corona. We checked the consistency of this spectral model on the basis of the variability patterns of its spectral parameters. We found that the two sources show different spectral states. We tentatively interpret the observed behaviour of NGC 1313 X-1 and X-2 within the framework of near Eddington and/or super-Eddington accretion. We also attempted to determine the chemical abundances in the local environment of NGC 1313 X-1 and X-2 from the EPIC and RGS spectra. The results appear to indicate subsolar metallicity for both sources.

description: Background
The fastest growing segment of the population is those age ≥80 who have the highest stroke incidence. Risk factor management is complicated by polypharmacy-related adverse events.

Aims
To characterize the impact of physical inactivity for stroke by age in a multi-ethnic prospective cohort study (NOMAS, n = 3298).

Methods
Leisure time physical activity was assessed by a validated questionnaire and our primary exposure was physical inactivity (PI). Participants were followed annually for incident stroke. We fit Cox-proportional hazard models to calculate hazard ratios and 95% confidence intervals (HR 95% CI) for the association of PI and other risk factors with risk of stroke including two-way interaction terms between the primary exposures and age (<80 vs. ≥80).

Results
The mean age was 69 ± 10.3 years and 562 (17%) were ≥80 at enrolment. PI was common in the cohort (40.8%). Over a median of 14 years, we found 391 strokes. We found a significant interaction of age ≥80 on the risk of stroke with PI (p = 0.03). In stratified models, PI versus any activity (adjusted HR 1.60, 95%CI 1.05–2.42) was associated with an increased risk of stroke among those ≥80.

Conclusion
Physical inactivity is a treatable risk factor for stroke among those older than age 80. Improving activity may reduce the risk of stroke in this segment of the population.
Nonlinear Behavior of Baryon Acoustic Oscillations from the Zel'dovich Approximation Using a Non-Fourier Perturbation Approach

description: Baryon acoustic oscillations are an excellent technique to constrain the properties of dark energy in the Universe. In order to accurately characterize the dark energy equation of state, we must understand the effects of both the nonlinearities and redshift space distortions on the location and shape of the acoustic peak. In this paper, we consider these effects using the Zel'dovich approximation and a novel approach to 2nd order perturbation theory. The second order term of the Zel'dovich power spectrum is built from convolutions of the linear power spectrum with polynomial kernels in Fourier space, suggesting that the corresponding term of the the Zel'dovich correlation function can be written as a sum of quadratic products of a broader class of correlation functions, expressed through simple spherical Bessel transforms of the linear power spectrum. We show how to systematically perform such a computation. We explicitly prove that our result is the Fourier transform of the Zel'dovich power spectrum, and compare our expressions to numerical simulations. Finally, we highlight the advantages of writing the nonlinear expansion in configuration space, as this calculation is easily extended to redshift space, and the higher order terms are mathematically simpler than their Fourier counterparts.

description: This paper, delivered at MPRG's conference in Winchester 2004, rapidly surveys the use of the clay industries that may have impacted on the manipulation of private and public space in western Europe. Did these changing rooms influence potters and the social context of pottery utilisation? The paper concludes that assemblages, with people at their core, must embrace all movable goods to revisit some of the earlier excavations of castles, palaces and monastic institutions and using modern methodology explain the differences. The results need to be presented in a more accessible manner.

description: There is limited empirical evidence to support the protective effects of physical activity in the prevention of hypertension among African Americans. The purpose of this study was to examine the association of physical activity with incident hypertension among African Americans. We studied 1311 participants without hypertension at baseline enrolled in the Jackson Heart Study, a community-based study of African Americans residing in Jackson, Mississippi. Overall physical activity, moderate–vigorous physical activity, and domain-specific physical activity (work, active living, household, and sport/exercise) were assessed by self-report during the baseline examination (2000–2004). Incident hypertension, assessed at examination 2 (2005–2008) and examination 3 (2009–2013), was defined as the first visit with systolic/diastolic blood pressure ≥140/90 mm Hg or self-reported antihypertensive medication use. Over a median follow-up of 8.0 years, there were 650 (49.6%) incident hypertension cases. The multivariable-adjusted hazard ratios (95% confidence interval) for incident hypertension comparing participants with intermediate and ideal versus poor levels of moderate–vigorous physical activity were 0.84 (0.67–1.05) and 0.76 (0.58–0.99), respectively (P trend=0.038). A graded, dose–response association was also present for sport/exercise-related physical activity (Quartiles 2, 3, and 4 versus Quartile 1: 0.92 [0.68–1.25], 0.87 [0.67–1.13], 0.75 [0.58–0.97], respectively; P trend=0.032). There were no statistically significant associations observed for overall physical activity, or work, active living, and household-related physical activities. In conclusion, the results of the current study suggest that regular moderate–vigorous physical activity or sport/exercise-related physical activity may reduce the risk of developing hypertension in African Americans.

description: In this work, we recalculate the charmless pure annihilation decays $B_s\to π^+ π^-$ and $B^0 \to K^+ K^-$ by using the perturbative QCD (pQCD) factorization approach, and compare the pQCD predictions with currently available experimental measurements. We used the same set of relevant input parameters and wave functions to make the calculations for the considered decay modes and found the following results: (a) one can provide a consistent pQCD interpretation for both the measured $Br(B_s^0 \to π^+ π^-)$ and $Br(B_d^0 \to K^+ K^-)$ simultaneously; (b) the pQCD predictions for $Br(B_s^0 \to π^+π^-)$ obtained by different authors are well consistent with each other; (c) our new pQCD prediction for $Br(B_d^0 \to K^+K^-)$ agree very well with the measured values from CDF and LHCb Collaboration; and (d) the CP-violating asymmetry ${\cal A}_{CP}(B_d^0 \to K^+K^-) \approx 16%$, which is large and may be detected at the LHCb experiment.

DeltaGamma Non-perturbative parameter sum rules
Creators: name: Rauh, Thomas
Publisher: name: Zenodo
Year: 2019

description: The mixing of $B_{s/d}$ and $\overline{B}_{s/d}$ mesons constitutes a FCNC

process and is therefore very sensitive to new physics effects and has the

potential to severely constrain models that could explain the current flavour

anomalies. We present SM predictions for the mixing observables based on a

sum rule determination of the required hadronic matrix elements of the full

basis of dimension-six operators, which is a competitive alternative to

lattice simulations. Results for the effects of a non-zero strange-quark

mass in $B_s$ mixing are shown for the first time. The reliability of the

heavy-quark expansion and sum rule results is demonstrated by considering

lifetime ratios of $B$ and $D$ mesons where we find very good agreement

with the experimental averages.

description: We calculate the three-body recombination rate into a shallow dimer in a gas of cold bosonic atoms near a Feshbach resonance using a two-channel contact interaction model. The two-channel model naturally describes the variation of the scattering length through the Feshbach resonance and has a finite effective range. We confront the theory with the available experimental data and show that the two-channel model is able to quantitatively describe the existing data. The finite effective range leads to a reduction of the scaling factor between the recombination minima from the universal value of 22.7. The reduction is larger for larger effective ranges or, correspondingly, for narrower Feshbach resonances.

description: We investigate the electromagnetic (EM) counterpart of gravitational waves (GWs) emitted by a supermassive black hole binary (SMBHB) through the viscous dissipation of the GW energy in an accretion disk and stars surrounding the SMBHB. We account for the suppression of the heating rate if the forcing period is shorter than the turnover time of the largest turbulent eddies. We find that the viscous heating luminosity in 0.1 solar mass stars can be significantly higher than their intrinsic luminosity, but still too low to be detected for extragalactic sources. The relative brightening is small for accretion disks.

description: Cracking and damage from crystallization of minerals in pores center on a wide range of problems, from weathering and deterioration of structures to storage of CO2 via in situ carbonation. Here we develop a theoretical and computational framework for modeling these crystallization-induced deformation and fracture in fluid-infiltrated porous materials. Conservation laws are formulated for coupled chemo-hydro-mechanical processes in a multiphase material composed of the solid matrix, liquid solution, gas, and crystals. We then derive an expression for the effective stress tensor that is energy-conjugate to the strain rate of a porous material containing crystals growing in pores. This form of effective stress incorporates the excess pore pressure exerted by crystal growth – the crystallization pressure – which has been recognized as the direct cause of deformation and fracture during crystallization in pores. Continuum thermodynamics is further exploited to formalize a constitutive framework for porous media subject to crystal growth. The chemo-hydro-mechanical model is then coupled with a phase-field approach to fracture which enables simulation of complex fractures without explicitly tracking their geometry. For robust and efficient solution of the initial–boundary value problem at hand, we utilize a combination of finite element and finite volume methods and devise a block-partitioned preconditioning strategy. Through numerical examples we demonstrate the capability of the proposed modeling frameworkfor simulating complex interactions among unsaturated flow, crystallization kinetics, and cracking in the solid matrix.

description: We propose a general method for predicting potentially good folders from a given number of amino acid sequences. Our approach is based on the calculation of the rate of convergence of each amino acid chain towards the native structure using only the very initial parts of the dynamical trajectories. It does not require any preliminary knowledge of the native state and can be applied to different kinds of models, including atomistic descriptions. We tested the method within both the lattice and off-lattice model frameworks and obtained several so far unknown good folders. The unbiased algorithm also allows to determine the optimal folding temperature and takes at least 3--4 orders of magnitude less time steps than those needed to compute folding times.
The effect of different interventions on the sensory and affective dimensions of dyspnea in patients with COPD during exercise

description: Background: Dyspnea is a complex sensation that has been recognized as a similar entity to the sensation of pain. Research has shown that dyspnea can be caused by a variety of diverse mechanisms and can be interpreted differently by each individual. Hyperoxia, heliox, and BiPAP are able to reduce dyspnea in patients with COPD but it is unknown how they specifically influence the affective (A1) and sensory (SI) dimensions of dyspnea during exercise. The aim of this study was to examine the extent to which hyperoxia, heliox and BiPAP alter A1 and SI scores and if changes in these dimensions of dyspnea are associated with improvements in exercise capacity. Methods: 10 patients with moderate to severe COPD (post-bronchodilator FEV1/FVC <0.7, 30%< FEV1 < 80% pred, >10 pack year history of smoking) who were exacerbation-free for at least six weeks prior to the study performed constant-load cycling at 75% of maximal work rate breathing air, hyperoxia (40% O₂, 60% N₂), heliox (21% O₂, 79% He), or BiPAP (pressure optimized for each individual). Results: At an isotime during exercise, hyperoxia reduced the sensory intensity of dyspnea (p=0.033). The change in A1 and SI were also significantly reduced compared to air with both hyperoxia (p=0.033, p=0.025, respectively) and heliox (p=0.047, p=0.041, respectively) but not with BiPAP. The A1/SI ratio was unchanged with all interventions compared to air. There were no significant changes in the sensory qualities of dyspnea with any intervention, except for the sensation of breathing a lot (rapidly, deeply, or heavily), which was significantly reduced with heliox at isotime. There were no significant differences in dyspnea measures or ventilatory parameters at end exercise. Conclusions: Hyperoxia and heliox altered the affective and sensory dimensions of dyspnea during exercise, leading to improvements in exercise time with hyperoxia. There were considerable individual differences in the reported quality of dyspnea scores, as well as exercise time. These findings suggest that phenotyping patients based on their specific type of dyspnea to a particular therapy before an exercise intervention may be warranted to enhance the known benefits of exercise for patients with COPD.

description: We report on a new approach to the calculation of Chern-Simons theory expectation values, using the mathematical underpinnings of loop quantum gravity, as well as the Duflo map, a quantization map for functions on Lie algebras. These new developments can be used in the quantum theory for certain types of black hole horizons, and they may offer new insights for loop quantum gravity, Chern-Simons theory and the theory of quantum groups.

description: In this Letter we point out that redshift surveys can break the degeneracy between the galaxy bias, the power spectrum normalization, σ_{8,0} and the growth factor, without the need for external information by using a simple and rather general parametrization for the growth rate, the well known γ-parametrization and measuring the power spectrum at least at two different redshifts. We find that in next-generation surveys like Euclid, σ_{8,0} and γcan be measured to within 1% and 5%, respectively, while the bias b(z) can be measured to within 1-2% in each of 14 equal-width redshift bins spanning 0.7<=z<=2.

description: Quantum beats in nonlinear spectroscopy of molecular aggregates are often attributed to electronic phenomena of excitonic systems, while nuclear degrees of freedom are commonly included into models as overdamped oscillations of bath constituents responsible for dephasing. However, molecular systems are coupled to various high-frequency molecular vibrations, which can cause the spectral beats hardly distinguishable from those created by purely electronic coherences. Models containing damped, undamped and overdamped vibrational modes coupled to an electronic molecular transition are discussed in this paper in context of linear absorption and two-dimensional electronic spectroscopy. Analysis of different types of bath models demonstrates how do vibrations map onto two-dimensional spectra and how the damping strength of the coherent vibrational modes can be resolved from spectroscopic signals.

description: We present a new code, named COCAL - Compact Object CALculator, for the computation of equilibriums and quasiequilibrium initial data sets of single or binary compact objects of all kinds. In the cocal code, those solutions are calculated on one or multiple spherical coordinate patches covering the initial hypersurface up to the asymptotic region. The numerical method used to solve field equations written in elliptic form is an adaptation of self-consistent field iterations in which Green's integral formula is computed using multipole expansions and standard finite difference schemes. We extended the method so that it can be used on a computational domain with excised regions for a black hole and a binary companion. Green's functions are constructed for various types of boundary conditions imposed at the surface of the excised regions for black holes. The numerical methods used in cocal are chosen to make the code simpler than any other recent initial data codes, accepting the second order accuracy for the finite difference schemes. We perform convergence tests for time symmetric single black hole data on a single coordinate patch, and binary black hole data on multiple patches. Then, we apply the code to obtain spatially conformally flat binary black hole initial data using boundary conditions including the one based on the existence of equilibrium apparent horizons.

description: We consider a desingularization Gamma of a Richardson variety X_w^v=X_w \cap X^v in the flag variety Fl(n)=GL(n)/B, obtained as a fibre of a projection from a certain Bott-Samelson variety Z. We then construct a basis of the homogeneous coordinate ring of Gamma inside Z, indexed by combinatorial objects which we call w_0-standard tableaux.

description: As the only directly imaged multiple planet system, HR 8799 provides a unique opportunity to study the physical properties of several planets in parallel. In this paper, we image all four of the HR 8799 planets at H-band and 3.3 microns with the new LBT adaptive optics system, PISCES, and LBTI/LMIRCam. Our images offer an unprecedented view of the system, allowing us to obtain H and 3.3$ micron photometry of the innermost planet (for the first time) and put strong upper-limits on the presence of a hypothetical fifth companion. We find that all four planets are unexpectedly bright at 3.3 microns compared to the equilibrium chemistry models used for field brown dwarfs, which predict that planets should be faint at 3.3 microns due to CH4 opacity. We attempt to model the planets with thick-cloudy, non-equilibrium chemistry atmospheres, but find that removing CH4 to fit the 3.3 micron photometry increases the predicted L' (3.8 microns) flux enough that it is inconsistent with observations. In an effort to fit the SED of the HR 8799 planets, we construct mixtures of cloudy atmospheres, which are intended to represent planets covered by clouds of varying opacity. In this scenario, regions with low opacity look hot and bright, while regions with high opacity look faint, similar to the patchy cloud structures on Jupiter and L/T transition brown-dwarfs. Our mixed cloud models reproduce all of the available data, but self-consistent models are still necessary to demonstrate their viability.
