description: The total syntheses of four structurally related, naturally occurring compounds, (±)­verrucosan-2β-ol (61), (±)-neoverrucosan-5β-ol (62), (±)-homoverrucosan-5β,-ol (63), and (±)-(3R, 4R, 5R, 6S, 9#)-cyatha-12,18-diene (64) are discussed in the first part of this thesis. In connection with the total syntheses of the natural products 61-64, a new bifunctional reagent mediated cyclohexenone annulation sequence was developed, but attempted application of this sequence to the natural product syntheses was not successful. The generality, scope and synthetic utility of this new annulation method are described in the second part of this thesis. The syntheses of the natural products 61-64 started with the conversion of 3 ­methylcyclohex-2-en-l-one (140) into the known bicyclic enone 179. Recently developed methodology from our laboratory was used as a key step and involved the stereoselective conjugate addition reaction of the cuprate reagent 192 to the enone 179 with control of the 5,6 ring-juncture stereochemistry to afford the ketone 60. A double alkylation of 60, first with the bifunctional reagent 281, and then with methyl iodide, provided the ketone 287. Functional group manipulations were used to convert 287 into 273, which underwent an aldol cyclization-dehydration sequence to provide the corresponding enone 72. Dissolving metal reduction of the latter material afforded the tricyclic ketone 171. From compound 171, diverging synthetic routes gave the cyathane natural product 64 and the three verrucosane­type natural products 61-63. Ring expansion of 171 and functional group manipulations led to 64. Conversion of 171 into the tricyclic enone 174 involved a series of functional group transformations. Separate synthetic routes from compound 174 led to (±)-neoverrucosan-5β­ol (62) or (±)-verrucosan-2β-ol (61), both of which reacted with acid to produce (±)­ homoverrucosan-5 (5β-ol (63). The four racemic natural products were tested against the P388 murine leukemia cell line and possessed cytotoxicity with ED₅₀'s in the range of 1.7­ 21 µg/mL. The newly developed cyclohexenone annulation sequence involved alkylation of N,N­dimethylhydrazones of general structure 32 with the Afunctional reagent 253 to provide 354. Conversion of 354 into the keto alkenyl iodide 356, followed by n-BuLi-mediated cyclization of 356 and oxidative rearrangement of the resultant allylic alcohol 358 provided the cyclohexenone 359. Each step is experimentally simple, tolerates a variety of ring sizes and functionality, and proceeds in very good yield. [Formula]

description: Based on the strongly lensed gravitational waves (GWs) from compact binary coalescence, we propose a new strategy to examine the fluid shear viscosity of dark matter (DM) in the gravitational wave domain, i.e., whether a GW experiences the damping effect when it propagates in DM fluid with nonzero shear viscosity. By assuming that the dark matter self-scatterings are efficient enough for the hydrodynamic description to be valid, our results demonstrate that future ground-based Einstein Telescope (ET) and satellite GW observatory (Big Bang Observer; BBO) may succeed in detecting any dark matter self-interactions at the scales of galaxies and clusters.

description: We analyzed HST/WFPC2 colour-magnitude diagrams (CMDs) of 15 populous Large Magellanic Cloud (LMC) stellar clusters with ages between ~ 0.3 Gyr and ~ 3 Gyr. These (V, B-V) CMDs are photometrically homogeneous and typically reach V \~ 22. Accurate and self-consistent physical parameters (age, metallicity, distance modulus and reddening) were extracted for each cluster by comparing the observed CMDs with synthetic ones. These determinations involved simultaneous statistical comparisons of the main-sequence fiducial line and the red clump position, offering objective and robust criteria to determine the best models. The models explored a regular grid in the parameter space covered by previous results found in the literature. In general, the best models show a satisfactory fit to the data, constraining well the physical parameters of each cluster. The age-metallicity relation derived by us presents a lower spread than similar results found in the literature for the same clusters. Our results are in accordance with the published ages for the oldest clusters, but reveal a possible underestimation of ages by previous authors for the youngest clusters. Our metallicity results in general agree with the ones based on spectroscopy of giant stars and with recent works involving CMD analyses. The derived distance moduli implied by the most reliable solutions, correlate with the reddening values, as expected from the non-negligible three-dimensional distribution of the clusters within the LMC. The inferred spatial distribution for these clusters is roughly aligned with the LMC disk, being also more scattered than recent numerical predictions, indicating that they were not formed in the LMC disk. The set of ages and metallicities homogeneously derived here can be used to calibrate integrated light studies applied to distant galaxies.

description: Using extremely deep (rms 3.3 microJy/bm) 1.4GHz sub-arcsecond resolution MERLIN + VLA radio observations of a 8'.5 by 8'.5 field centred upon the Hubble Deep Field North, in conjunction with Spitzer 24 micron data we present an investigation of the radio-MIR correlation at very low flux densities. By stacking individual sources within these data we are able to extend the MIR-radio correlation to the extremely faint (~microJy and even sub-microJy) radio source population. Tentatively we demonstrate a small deviation from the correlation for the faintest MIR sources. We suggest that this small observed change in the gradient of the correlation is the result of a suppression of the MIR emission in faint star-forming galaxies. This deviation potentially has significant implications for using either the MIR or non-thermal radio emission as a star-formation tracer at low luminosities.

description: I discuss different approaches to finite density lattice QCD. In particular, I focus on the structure of the phase diagram and discuss attempts to determine the location of the critical end-point. Recent results on the transiton line as function of the chemical potential ($T_c(μ_q)$) are reviewed. Along the transition line, hadronic fluctuations have been calculated, which can be used to characterize properties of the Quark Gluon plasma and eventually can also help to identify the location of the critical end-point in the QCD phase diagram on the lattice and in heavy ion experiments. Furthermore, I comment on the structure of the phase diagram at large $μ_q$.

PLAYING IN THE MARGINS: MEDIEVAL AND RENAISSANCE MARGINALIA
Creators: name: Cole, Helena Elizabeth
Publisher: name: Maryland Shared Open Access Repository
Year: 2010

description: This study explores the differences and similarities (in content, intent, purpose and effect) in Renaissance and medieval marginalia, exploring at what point the marginalia cease to be, by definition, "marginal" and instead become, through their various interactions with texts they surround, integral and indispensable to the work itself. Attention is paid to the historical contexts in which the marginalia were written or, as in the case of medieval marginal images studied, depicted. The primary argument of the study is that the marginalia of both periods play with their parent texts through multiple framings and layers, and that these games were intentional on the part of the authors and/or artists who had set out deliberately to create sub-texts within others' (or sometimes their own) works. The study also examines the history of marginalia throughout the Middle Ages and Renaissance, as well as the reasons behind its use's demise in the immediate subsequent centuries. An in-depth analysis of the marginalia in one work—Sir Thomas More's Utopia—demonstrates how this practice "played out" in this particular, and heavily marginated, text. Attention is also paid to Utopia's prefatory and post-script materials, which in turn add another layer of play—doing to the text as a whole what the marginalia did to the page.

description: In this paper we present three different results dealing with the number of $(\leq k)$-facets of a set of points: 1. We give structural properties of sets in the plane that achieve the optimal lower bound $3\binom{k+2}{2}$ of $(\leq k)$-edges for a fixed $0\leq k\leq \lfloor n/3 \rfloor -1$; 2. We give a simple construction showing that the lower bound $3\binom{k+2}{2}+3\binom{k-\lfloor \frac{n}{3} \rfloor+2}{2}$ for the number of $(\leq k)$-edges of a planar point set appeared in [Aichholzer et al. New lower bounds for the number of ($\leq k$)-edges and the rectilinear crossing number of $K_n$. {\em Disc. Comput. Geom.} 38:1 (2007), 1--14] is optimal in the range $\lfloor n/3 \rfloor \leq k \leq \lfloor 5n/12 \rfloor -1$; 3. We show that for $k < \lfloor n/(d+1) \rfloor$ the number of $(\leq k)$-facets of a set of $n$ points in general position in $\mathbb{R}^d$ is at least $(d+1)\binom{k+d}{d}$, and that this bound is tight in the given range of $k$.

description: We use the spectra of 22,000 nearby early-type galaxies from the Sloan Digital Sky Survey (SDSS) to determine the age distribution of these galaxies as a function of their velocity dispersion sigma_v in the range 100 km/s < sigma_v < 280 km/s. We then combine the inferred age-distributions with the local abundance of spheroids, including early-type galaxies and late-type bulges, to predict the evolution of the quasar luminosity function (LF) in the redshift range 0 at fixed sigma_v. These assumptions require that the SMBH remnants of quasars with bolometric luminosity below L_bol=10^{12.5} f_Edd L_sun reside predominantly in bulges of late type galaxies. We find that evolution of the observed quasar LF can be fit over the entire redshift range in this simple model, 0=0.3-0.5. We find no evidence that any of the model parameters evolves with redshift, supporting the strong connection between the formation of stars and nuclear SMBHs in spheroids.

description: The recent progress on (Si)GeSn optoelectronic devices holds a great promising for photonic integration on the Si substrate. In parallel to the development of bulk devices, the (Si)GeSn based quantum wells (QWs) have been investigated aiming to improve the device performance. While the multiple QW structure is preferred for the device application, the single quantum well (SQW) is more suitable for optical property study. In this work, a comprehensive study of a SiGeSn/GeSn SQW was conducted. The calculated band diagram provided the band alignment and energies of possible transitions. The SQW features the direct bandgap well with L-Γ valley energy separation of 50 meV, and the barrier heights for both electron and hole are greater than 80 meV. Using two continuous-wave and two pulsed pumping lasers, the analysis of PL spectra allows for identifying different transitions and for better understanding the SQW optical properties. The study could provide the guidance for advancing the future QW design towards device applications.

description: A large class of new exact solutions to the steady, incompressible Euler equation on the plane is presented. These hybrid solutions consist of a set of stationary point vortices embedded in a background sea of Liouville-type vorticity that is exponentially related to the stream function. The input to the construction is a "pure" point vortex equilibrium in a background irrotational flow. Pure point vortex equilibria also appear as a parameter $A$ in the hybrid solutions approaches the limits $A\to 0,\infty$. While $A\to 0$ reproduces the input equilibrium, $A\to\infty$ produces a new pure point vortex equilibrium. We refer to the family of hybrid equilibria continuously parametrised by $A$ as a "Liouville link". In some cases, the emergent point vortex equilibrium as $A\to\infty$ can itself be the input for a second family of hybrid equilibria linking, in a limit, to yet another pure point vortex equilibrium. In this way, Liouville links together form a "Liouville chain". We discuss several examples of Liouville chains and demonstrate that they can have a finite or an infinite number of links. We show here that the class of hybrid solutions found by Crowdy (2003) and by Krishnamurthy et al. (2019) form the first two links in one such infinite chain. We also show that the stationary point vortex equilibria recently studied by Krishnamurthy et al. (2020) can be interpreted as the limits of a Liouville link. Our results point to a rich theoretical structure underlying this class of equilibria of the 2D Euler equation.

Nitrates and nitrites as food additives, their uses and dangers; a consumer analysis.
Creators: name: Collier, M. Ann
Publisher: name: Maryland Shared Open Access Repository
Year: 1979

description: The following study examines conflictive information available to the public relating to the benefits and dangers of human consumption of the food additives nitrates and nitrites. These additives are presently used in most luncheon meats, a much utilized food item in the American diet. Current periodicals, books, and personal communications were searched in order to determine the opinions of government, industry, and independent scientists in regards to the valid uses and health risks of ingesting these two additives. This paper is not meant to be a purely scientific literature search. It is an interdisciplinary consumer's analysis of the health, political, and economic problems of retaining versus removing the additives from meat and meat products. It is not written in a highly technical manner, and many scientific terms relating to the subject are defined in terminology that helps the average consumer better understand the issues involved. Recommendations for alternative ways to reduce or eliminate one's nitrate and nitrite intake are listed at the end of the paper.

description: Studies of individual quantum systems, which have led to considerable progress in our understanding of quantum physics, have traditionally been associated with atomic gases. In the last decades however, the emphasis has shifted towards solid-state systems, which are much more practical for applications. In particular, a new field has recently emerged that is concerned with the study of quantum systems based on single spins localized near point defects in crystalline solids. One such system is the nitrogen-vacancy (NV) defect in diamond. Initially used as an experimental breadboard for testing concepts of quantum physics and quantum computation, the NV defect was soon proposed as a sensitive magnetometer, capable of detecting minute magnetic fields, down to ultimate level of single spins. This atomic-sized magnetometer can be used as a standalone sensor, or integrated into an imaging system providing spatial resolution down to the atomic scale. Diamond-based instruments thus offer new pathways to probe the magnetism of matter from the mesoscale down to the nanoscale. This book chapter gives an overview of the field of diamond-based magnetic sensing and imaging, with an emphasis on already demonstrated applications of this technology. The chapter is divided into three main sections. In Section 2, the underlying physics and methods of diamond-based magnetometry are described. Section 3 is devoted to various experimental implementations that employ this new class of sensors for magnetic sensing and imaging. Finally, some recent applications are presented in Section 4.

ROSIE THE RIVETER: A MISREPRESENTATION OF THE EXPERIENCE OF WORKING WOMEN DURING WORLD WAR II
Creators: name: Colwell, Tess
Publisher: name: Maryland Shared Open Access Repository
Year: 2009

description: World War II opened employment doors for many women who otherwise would not have had the opportunity. The images of Rosie the Riveter have become the visual representation of this labor shift. Rosie evolved into a cultural and feminist icon. Yet much of what Rosie represents today is not an accurate portrayal of the experiences of working women at the time. Not all women were young, beautiful and housewives- turned-laborers as the images portrayed. Many female workers were working class, minority, and had already been in the labor force for some time. Rosie the Riveter represents feminism today, but at the time her creation represented nationalism. The postwar view of women reverted to pre-war standards; women returned to their homes as wives and mothers. Though change was not outwardly apparent at the war's end, women who entered the labor force during the war planted the seeds that bloomed into the woman's movement of the late 1960s and 1970s. To view Rosie as a feminist is to view the real working women during WWII out of historical and cultural contexts.

description: We use the spectra of ~ 22,000 early-type galaxies, selected from the Sloan Digital Sky Survey, to infer the ages, metallicities and star formation histories of these galaxies. We find clear evidence of "downsizing", i.e. galaxies with larger velocity dispersion have older stellar populations. In particular, most early-type galaxies with velocity dispersion exceeding 200 km s-1 formed more than 90% of their current stellar mass at redshift z > 2.5. Therefore, star formation was suppressed around this redshift. We also show that chemical enrichment was rapid, lasting 1-2 Gyr and find evidence that [Fe/H] is sub-solar. We study the robustness of these results by comparing three different approaches: using (i) Lick absorption line indices; (ii) fitting a single-burst stellar population model to the whole spectrum (lines+continuum); and (iii) reconstructing the star formation and metallicity histories in multiple age-bins, providing a method to measure mass-weighted ages and metallicities. We find good agreement between the luminosity-weighted ages and metallicities computed with these three methods.

description: Based on simplified one-dimensional steady-state analysis of thermoelectric phenomena and on analogies between thermal and electrical domains, we propose both lumped and distributed parameter electrical models for thermoelectric devices. For lumped parameter models, constant values for material properties are extracted from polynomial fit curves evaluated at different module temperatures (hot side, cold side, average, and mean module temperature). For the case of distributed parameter models, material properties are calculated according to the mean temperature at each segment of a sectioned device. A couple of important advantages of the presented models are that temperature dependence of material properties is considered and that they can be easily simulated using an electronic simulation tool such as SPICE. Comparisons are made between SPICE simulations for a single-pellet module using the proposed models and with numerical simulations carried out with Mathematica software. Results illustrate accuracy of the distributed parameter models and show how inappropriate is to assume, in some cases, constant material parameters for an entire thermoelectric element.

description: Developing agents that can perform complex control tasks from high dimensional observations such as pixels is challenging due to difficulties in learning dynamics efficiently. In this work, we propose to learn forward and inverse dynamics in a fully unsupervised manner via contrastive estimation. Specifically, we train a forward dynamics model and an inverse dynamics model in the feature space of states and actions with data collected from random exploration. Unlike most existing deterministic models, our energy-based model takes into account the stochastic nature of agent-environment interactions. We demonstrate the efficacy of our approach across a variety of tasks including goal-directed planning and imitation from observations.

NMR imaging investigations of swelling-controlled drug delivery

description: Important current developments in pharmaceutical science are in the area of formulation technology where the ultimate goal is to control the rate and duration of drug release. Swelling-controlled drug delivery systems utilize the swelling of a hydrophilic polymer to control drug release. NMR spectroscopy and NMR imaging are presented as non-invasive and non-destructive techniques that can provide both chemical and spatial information during the swelling of such controlled release systems. The tablet system chosen for this study contained hydroxypropylmethylcellulose (HPMC) as the hydrophilic polymer and one of two fluorinated compounds, triflupromazine- HCl or 5-fluorouracil, as model drugs. The geometry for the tablet swelling was chosen to simplify the system to one where the transport processes were one-dimensional. Water distributions were determined by one-dimensional ¹H NMR imaging. HPMC distributions were not measured directly but were calculated from the calibration of the T₂ relaxation times of the water as a function of HPMC concentration. The presence of air bubbles in the swollen tablet resulted in experimentally determined polymer distributions which contained up to 45% more HPMC than the known weight of HPMC in the tablet. When the air in the tablet was removed under vacuum prior to the imaging experiment, the total weight of HPMC from the experimental distributions was much closer to the actual weight of HPMC in the tablet. The comparison of the polymer distribution and the drug distributions, obtained from one-dimensional ¹⁹F NMR imaging investigations of tablets containing model drugs, showed that most of the triflupromazine-HCl remained within the swollen polymer tablet while more of the 5-fluorouracil was able to escape. The critical condition for drug release from the tablet was the relationship between the diffusivity of the drug and the expansion rate of the tablet. For triflupromazine-HCl, the required rate of diffusion was not reached until the region of tablet erosion. In contrast, the diffusion coefficient of 5-fluorouracil in 30% HPMC was large enough that the drug diffused faster than the polymer expanded. Preliminary modelling calculations assuming Fickian diffusion and a segmented-tablet model were performed.

description: There are many statistics software packages on the market today. By and large, they exist for one purpose, and they serve that purpose well: to provide the experienced scientist with a full range of statistical procedures for the field and laboratory. The user of such software is expected to know quite a bit about computers and statistics. As a result, few high school and college students can easily utilize most existing statistics software packages. The purpose of ENvironmental COMputer - ASSisted EDucation, ENCOMPASSED: STATISTICS FOR FIELD BIOLOGISTS is to provide the novice with an easy-to -use package of the basic descriptive statistics important for field biology. The program is general, so it can be used by people in other disciplines, too. It is powerful enough for use by active researchers as well as by students. Any student who can turn on a PC and insert a disk into a floppy drive can use this software package TODAY. It is highly interactive and takes the user step-by-step through the various statistics routines. As a result, this instruction manual is very brief. The only way to learn how to use a software package is to use the software package. So, go to it!

description: To a compact Lie group $G$ one can associate a space $E(2,G)$ akin to the poset of cosets of abelian subgroups of a discrete group. The space $E(2,G)$ was introduced by Adem, F. Cohen and Torres-Giese, and subsequently studied by Adem and Gómez, and other authors. In this short note, we prove that $G$ is abelian if and only if $π_i(E(2,G))=0$ for $i=1,2,4$. This is a Lie group analogue of the fact that the poset of cosets of abelian subgroups of a discrete group is simply--connected if and only if the group is abelian.

description: We demonstrate the capabilities of a high temperature measurement set-up recently developed at our institute. It is dedicated to the characterization of semiconductor devices and test structures in the temperature range from room temperature up to 500 degrees C and higher. A detailed description of the experimental aquipment is given. Its practical use is demonstrated by measuring temperature-dependent charcteristics of silicon VDMOSFET and IGBT devices as well as SiC-diodes. For the silicon devices, numerical simulations based on recently developed high temperature physical models were also performed in order to gain a deeper understanding of the measured data, together with a revalidation of the model parameters.

description: This paper reviews recent progress in the study of rare gas films on quasicrystalline surfaces. The adsorption of Xe on the 10-fold surface of decagonal Al-Ni-Co was studied using low-energy electron diffraction (LEED). The results of these studies prompted the development of a theoretical model, which successfully reproduced the thermodynamic parameters found in the experiment. Grand canonical Monte Carlo (GCMC) simulations for Xe produced structures agreed with the experimental observations of the adsorption structures and provided a deeper insight into the nature of the ordering. A first-order commensurate-incommensurate transition that involves a transition from a quasicrystalline five-fold stucture to a periodic hexagonal structure was discovered and characterized for the Xe monolayer. The five rotational domains of the hexagonal structure observed in the LEED study were shown in the GCMC study to be mediated by pentagonal defects that are entropic in nature, and not by substrate defects. The GCMC study found an absence of any such transition for Kr, Ar and Ne on the same surface. A detailed analysis of this transition led to the conclusion that the formation of the hexagonal layer depends on matching the gas and substrate characteristic lengths.

Behavioral aggression interactions and aggression levels between juvenile Orconectes rusticus and juvenile Orconectes virilis.

description: Orconectes rusticus, a crayfish species native to the Ohio River Valley, is expanding its home range and has recently been found as far south and east as the Monocacy River, Frederick County, Maryland. In the Monocacy, the most abundant crayfish, 0. virilis, is being displaced as 0. rusticus invades the river. A possible reason for this trend is that 0. rusticus obtain superior resources due to higher aggression levels and behavioral dominance. Aggression levels and behavioral dominance of juvenile 0. rusticus and juvenile 0. virilis were examined through interspecies and intraspecies, head to head, size matched agonistic bouts. Juvenile 0. virilis exhibited higher aggression levels and to also won behavioral dominance over juvenile 0. rusticus in this study. My results suggest that juvenile aggression and behavioral dominance is not the mechanism 0. rusticus uses to outcompete 0. virilis, therefore, other life history and ecological mechanisms should be explored.
Numerical simulations of the Warm-Hot Intergalactic Medium

description: In this paper we review the current predictions of numerical simulations for the origin and observability of the warm hot intergalactic medium (WHIM), the diffuse gas that contains up to 50 per cent of the baryons at z~0. During structure formation, gravitational accretion shocks emerging from collapsing regions gradually heat the intergalactic medium (IGM) to temperatures in the range T~10^5-10^7 K. The WHIM is predicted to radiate most of its energy in the ultraviolet (UV) and X-ray bands and to contribute a significant fraction of the soft X-ray background emission. While O VI and C IV absorption systems arising in the cooler fraction of the WHIM with T~10^5-10^5.5 K are seen in FUSE and HST observations, models agree that current X-ray telescopes such as Chandra and XMM-Newton do not have enough sensitivity to detect the hotter WHIM. However, future missions such as Constellation-X and XEUS might be able to detect both emission lines and absorption systems from highly ionised atoms such as O VII, O VIII and Fe XVII.

description: Photon-pair generation must satisfy both the energy conservation and phase-matching conditions with a specific pump wavelength and dispersion of nonlinear optical medium, but finding a photon-pair, which has a desired specific wavelength, generation medium is challenging. Here, we present a method to create photon pairs that functions efficiently even the pump wavelength is much larger than the zero GVD wavelength of medium. In this study, we employ short SMF-28 fibers having ~1310 nm zero GVD wavelength and C-band pump (1552.52 nm) to generate C-band photon pairs. The measured pair generation rate and coincidence-to-accidental ratios are comparable to those from a long dispersion-shifted fiber. Polarization-entangled states are prepared, and an S value of 2.659 +- 0.094 is achieved from Bell inequality measurements. Our results indicate that the use of a short SFWM medium yields adequate photon-pair generation rates regardless of its dispersion properties in almost any material at any pump wavelength.

description: Ultra High Energy (UHE) Cosmic Rays, UHECR, may graze high altitude atmosphere leading to horizontal upward air-showers. Also PeVs electron antineutrino hitting electron in atmosphere may air-shower at W boson resonant mass. On the other side ultra high energy muon and electron neutrinos may also lead, by UHE neutrinos mass state mixing, to the rise of a corresponding UHE Tau neutrino flavor; the consequent UHE tau neutrinos, via charge current interactions in matter, may create UHE taus at horizons (Earth skimming neutrinos or Hor-taus) whose escape in atmosphere and whose consequent decay in flight, may be later amplified by upward showering on terrestrial, planetary atmospheres. Indeed because of the finite terrestrial radius, its thin atmosphere size its dense crust, the UHE tau cannot extend much more than 360 kilometers in air, corresponding to an energy of about 7.2 EeV, near but below GZK cut-off ones; on the contrary Jupiter (or even Saturn) may offer a wider, less dense and thicker gaseous layer at the horizons where Tau may loose little energy, travel longer before decay and rise and shower at 4-6 10^{19} eV or ZeV extreme energy. Titan atmosphere may open a rare window of opportunity for Up-ward Taus at PeVs. Also solar atmosphere may play a role, but unfortunately tau-showers secondaries maybe are too noisy to be disentangled, while Jupiter atmosphere, or better, Saturn one, may offer a clearer imprint for GZK (and higher Z-Burst) Tau showering, well below the horizons edges.
