description: In 1963-71, a group of people, myself included, formulated and perfected a new approach to physics problems, which eventually came to be known under the names of scaling, universality, and renormalization. This work formed the basis of a wide variety of theories ranging from its starting point in critical phenomena, and moving out to particle physics and relativity and then into economics and biology. This work was of transcendental beauty and of considerable intellectual importance. This left me with a personal problem. What next? Constructing the answer to that question would dominate the next 45 years of my professional life. I would try to: * Help in finding and constructing new fields of science * Do research and give talks on science/society borderline * Provide helpful, constructive criticism of scientific and technical work * Help students and younger scientists * Demonstrate scientific leadership

description: Reionizing the Universe with galaxies appears to require significant star formation in low-mass halos at early times, while local dwarf galaxy counts tell us that star formation has been minimal in small halos around us today. Using simple models and the ELVIS simulation suite, we show that reionization scenarios requiring appreciable star formation in halos with $M_{\rm vir} \approx 10^{8}\,M_{\odot}$ at $z=8$ are in serious tension with galaxy counts in the Local Group. This tension originates from the seemingly inescapable conclusion that 30 - 60 halos with $M_{\rm vir} > 10^{8}\,M_{\odot}$ at $z=8$ will survive to be distinct bound satellites of the Milky Way at $z = 0$. Reionization models requiring star formation in such halos will produce dozens of bound galaxies in the Milky Way's virial volume today (and 100 - 200 throughout the Local Group), each with $\gtrsim 10^{5}\,M_{\odot}$ of old stars ($\gtrsim 13$ Gyr). This exceeds the stellar mass function of classical Milky Way satellites today, even without allowing for the (significant) post-reionization star formation observed in these galaxies. One possible implication of these findings is that star formation became sharply inefficient in halos smaller than $\sim 10^9 \,M_{\odot}$ at early times, implying that the high-$z$ luminosity function must break at magnitudes brighter than is often assumed (at ${\rm M_{UV}} \approx -14$). Our results suggest that JWST (and possibly even HST with the Frontier Fields) may realistically detect the faintest galaxies that drive reionization. It remains to be seen how these results can be reconciled with the most sophisticated simulations of early galaxy formation at present, which predict substantial star formation in $M_{\rm vir} \sim 10^8 \, M_{\odot}$ halos during the epoch of reionization.

title: Prehabilitation Before Lumpectomy Can Prevent Loss of Range of Motion

Publisher: name: eScholarship@UMMS
Year: 2015

description: Case Diagnosis: On intake exam, patient reported twenty year history of shoulder pain and history of bilateral subacromial bursitis . On the day of the exam, she rated her left shoulder pain (ipsilateral to breast cancer) at 2/10. Physical exam showed tenderness over left subacromial bursa, pain with resisted shoulder abduction and external rotation and ROM limited 120 degrees or less bilaterally.

Case Description: Here, we report the case of a 73 year old woman with a 20 year history of bilateral subacromial bursitis and left shoulder pain who began an independent daily shoulder exercise regimen as instructed by a physiatrist 2.5 weeks prior to left sided lumpectomy for breast cancer, and continued the exercises following the operation. One month post-surgery, physical exam revealed no loss in range of motion (ROM) in flexion and abduction of the left and right shoulders. Patient reported intermittent pain, manageable with NSAIDs, which started only after tamoxifen use.

Discussion: Decline in physical functioning such as loss of ROM, decreased strength, and pain following surgery for breast cancer is a well-documented phenomenon associated with difficulties in performing activities of daily living (ADL). Studies have shown that rehabilitation interventions during treatment period following breast cancer surgery result in improvements in shoulder and arm function; however, no study to date investigated the effectiveness of interventions initiated before surgery (prehabilitation) for breast cancer.

Conclusions: A daily exercise regimen prior to and following lumpectomy for breast cancer may prevent the development of shoulder dysfunction that is often reported in the cancer treatment period.
Essays on education and discrimination
Creators: name: Wu, Yuanting

Year: 2020

description: In Chapter 1, I investigate the migration response of college students to tuition differences between states, using variation introduced by tuition regional reciprocity agreements. Out-of-state students generally pay higher tuition than in-state students, but reciprocity agreements reduce the premium paid by students from other states in the agreement (sometimes to zero). I examine migration between directed pairs of states, with the tuition difference faced by a potential migrant as the covariate of interest. By instrumenting the tuition difference with a binary variable indicating the pair of states’ membership in a common regional reciprocity agreement, I find that a one percent decrease in the nonresident tuition of the destination state due to the regional reciprocity agreements would increase nonresident students’ inflow to the destination state by 0.4-0.5%. The reduced form shows that having a regional reciprocity agreement between states increases college migration between states by 29%.In Chapter 2, I provide a new method to decompose discrimination by Chinese employers into customer and coworker discrimination. Using data from an online job board, I relate employer advertisements for beautiful and tall applicants to oc- cupational job requirements as measured by the American O*NET data. I find that employers hiring in occupations with more contact with customers are more likely to require beautiful applicants in their job ads and employers hiring in occupations with more contact with coworkers are more likely to require tall applicants in their job ads. Customer discrimination plays a more important role in terms of contributions to the R-squared for both beauty and height requirements than coworker discrimination. The determinants of requiring tall applicants are similar for ads requesting males and females. For beauty, on the other hand, the effect of customer contact is driven by jobs requesting females, while the effect of coworker contact is driven by jobs requesting males.In Chapter 3, I compare how the gender wage gap evolves with age for occupations with different levels of contact with the public, coworkers, and customers. I use the O*NET data describing occupational job requirements to create indices of contact by occupation. I merge these indices with worker data from the Current Population Survey. I find suggestive evidence that the gender wage gap grows faster with age in occupations with greater overall contact; the evidence is stronger and statistically significant for occupations with high direct customer contact and with high public contact. This link is stronger for non-college graduates than more educated workers. I hypothesize that perceptions of how male and female beauty change with age could explain the results.

description: Using the MOSFIRE near-infrared multi-slit spectrograph on the Keck 1 Telescope, we have secured high signal-to-noise ratio absorption line spectra for six massive galaxies with redshift 2 < z < 2.5. Five of these galaxies lie on the red sequence and show signatures of passive stellar populations in their rest-frame optical spectra. By fitting broadened spectral templates we have determined stellar velocity dispersions and, with broad-band HST and Spitzer photometry and imaging, stellar masses and effective radii. Using this enlarged sample of galaxies we confirm earlier suggestions that quiescent galaxies at z > 2 have small sizes and large velocity dispersions compared to local galaxies of similar stellar mass. The dynamical masses are in very good agreement with stellar masses (log Mstar/Mdyn = -0.02 +/- 0.03), although the average stellar-to-dynamical mass ratio is larger than that found at lower redshift (-0.23 +/- 0.05). By assuming evolution at fixed velocity dispersion, not only do we confirm a surprisingly rapid rate of size growth but we also consider the necessary evolutionary track on the mass-size plane and find a slope alpha = dlogR / dlogM > ~2 inconsistent with most numerical simulations of minor mergers. Both results suggest an additional mechanism may be required to explain the size growth of early galaxies.

description: We study the dynamics of two strongly interacting bosons with an additional impurity atom trapped in a harmonic potential. Using exact numerical diagonalization we are able to fully explore the dynamical evolution when the interaction between the two distinct species is suddenly switched on (quenched). We examine the behavior of the densities, the entanglement, the Loschmidt echo and the spectral function for a large range of inter-species interactions and find that even in such small systems evidence of Anderson's orthogonality catastrophe can be witnessed.

Activists or administrators?: the influence of social movements on entrepreneurs' enactment of social issues
Creators: name: Fultz, Andrew
Publisher: name: No Publisher Supplied
Year: 2020

description: Social issues often trigger both local and diffuse prosocial organizing efforts, including local prosocial venturing and broader social movements. Yet, despite the frequent co-occurrence of these two forms of prosocial organizing—organizing aimed at benefiting others by relieving their hardship and/or promoting their welfare—and their potential similarities and synergies, their research streams have developed independently. Prior studies of prosocial venturing are often decontextualized, owing to an ongoing focus on individual and hyper-local explanations of prosocial venturing that neglect the broader environment, while social movement scholars often neglect studying small, grassroots organizations in favor of larger, more prominent social movement organizations. As a result, little is known about how social movements might influence local prosocial venturing. At the same time, social issues also trigger a variety of local responses, as prosocial entrepreneurs often vary widely in the ways they define social issues and the strategies they employ to address them—yet existing theory on prosocial venturing gives little insight into what drives these differential enactments of social issues. A small but growing number of studies at the intersection of prosocial venturing and social movements suggests linking these two research streams may hold the key to understanding systematic variation between prosocial ventures, yet these studies leave unanswered critical questions about the theoretical mechanisms through which movements may influence ventures. In this study, I conduct a longitudinal inductive field study of the founders of 11 campus food pantries that operate in parallel with social movements around student hunger and basic needs on campus, in order to understand how and why social movements shape the way prosocial entrepreneurs enact social issues. My central finding and answer to this question is that variation in founders’ identification with social movements shapes whether or not they enact a social issue as stigmatized, which in turn shapes their strategies for responding to the issue. These findings hold important implications for research on prosocial venturing and social movements, for the relationship between the two, and for research on organizational stigma, while also suggesting a number of promising directions for future research.

Initial state radiation effects in inclusive $J/ψ$ production at B factories

Year: 2014
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Based on Monte Carlo techniques, we analyze the initial state radiation (ISR) effects in prompt $\jpsi$ inclusive production at B factories. ISR enhances cross section $σ(e^-e^+\to\jpsi+gg+X)$ by about $15-25\%$, which is almost the same size as the QCD and relativistic correction. Moreover, ISR slightly changes $σ(e^-e^+\to\jpsi+c\bar{c}+X)$. The $\jpsi$ momentum spectrum in $e^-e^+\to\jpsi+gg+X$ and in $e^-e^+\to\jpsi+c\bar{c}+X$ is softer after the photon showering from the initial $e^{\pm}$ beam radiation. After combining the QCD,relativistic, and ISR corrections,a more precise theoretical result is obtained. The new result provides a more stringent constraint of the color-octet contribution to $σ(e^-e^+\to\jpsi+X_{\rm{non-}c\bar{c}})$.

description: Liquid-argon scintillation detectors are used in fundamental physics experiments and are being considered for security applications. Previous studies have suggested that the addition of small amounts of xenon dopant improves performance in light or signal yield, energy resolution, and particle discrimination. In this study, we investigate the detector response for xenon dopant concentrations from 9 +/- 5 ppm to 1100 +/- 500 ppm xenon (by weight) in 6 steps. The 3.14-liter detector uses tetraphenyl butadiene (TPB) wavelength shifter with dual photomultiplier tubes and is operated in single-phase mode. Gamma-ray-interaction signal yield of 4.0 +/- 0.1 photoelectrons/keV improved to 5.0 +/- 0.1 photoelectrons/keV with dopant. Energy resolution at 662 keV improved from (4.4 +/- 0.2)% (σ) to (3.5 +/- 0.2)% (σ) with dopant. Pulse-shape discrimination performance degraded greatly at the first addition of dopant, slightly improved with additional additions, then rapidly improved near the end of our dopant range, with performance becoming slightly better than pure argon at the highest tested dopant concentration. Some evidence of reduced neutron scintillation efficiency with increasing dopant concentration was observed. Finally, the waveform shape outside the TPB region is discussed, suggesting that the contribution to the waveform from xenon-produced light is primarily in the last portion of the slow component.

description: Abstract:
Because limestone groundwater flows mainly In discrete openings, limestone aquifers are fundamentally different from aquifers In granular rocks. A digital computer program which simulates flow in a limestone aquifer as a pipe network was written and compared with the Sinkhole Plain aquifer of west-central Kentucky.
A reasonably good fit between observed parameters of the aquifer and those calculated were obtained under assumed conditions of both laminar and turbulent now In the aquifer. The Indicated gross permeablllty of the aquifer is 5600 melnzers with an assumed aquifer thickness of 100 feet. The location and discharge of springs along the streams bounding the aquifer are predicted.
With further refinements to the computational routines, additional features of the aquifer can be modelled, and more refined predictions can be made of water budget parameters, location of flow paths, and development of the aquifer.

We prove that the variance of this quantity with respect to the couplings grows proportionally to the volume in any dimension greater than or equal to two. As an illustration of potential applications, we use this result to restrict the possible structure of Gibbs states in two dimensions.

description: Purpose: Picture stimuli are essential materials for language research and clinical practice. Here, we generated a modern, full-color set of 310 illustrations representing a carefully designed, culturally sensitive list of imageable nouns. We normed the images in a diverse sample of healthy adults, so the images can be used in various populations, including older adults.Method: We recruited a diverse online sample of 200 adults ages 19–76 years. Participants typed a name for each picture and reported how familiar they were with the item (familiarity) and how well the illustration matched their mental image of the item (image agreement). We assessed relationships among these three measures, between these measures and word features (e.g., frequency, length), and between these measures and demographic characteristics of our sample.Results: Two hundred ninety-seven of 310 items had 70% or higher name agreement among participants. Most items had good to excellent image agreement and familiarity. The image measures showed expected relationships with relevant word features (e.g., frequency, length). Older age was associated with higher image agreement and familiarity but not written naming accuracy. As a group, Black participants demonstrated lower written naming accuracy than White and mixed race participants. Education, sex, and self-reported multilingualism were not significantly related to image measures.Conclusions: We generated a novel set of illustrations with strong name agreement, familiarity, and image agreement, which are suitable for a variety of uses in research and clinical settings. Our normative data suggest a future need for item-level analysis to explore variability in performance across different racial groups.Supplemental Material S1.

description: f-divergence estimation is an important problem in the fields of information theory, machine learning, and statistics. While several divergence estimators exist, relatively few of their convergence rates are known. We derive the MSE convergence rate for a density plug-in estimator of f-divergence. Then by applying the theory of optimally weighted ensemble estimation, we derive a divergence estimator with a convergence rate of O(1/T) that is simple to implement and performs well in high dimensions. We validate our theoretical results with experiments.

description: We analyze the quantum-corrected moduli space of D7-brane position moduli with special emphasis on inflationary model building. D7-brane deformation moduli are key players in two recently proposed inflationary scenarios: The first, D7-brane chaotic inflation, is a variant of axion monodromy inflation which allows for an effective 4d supergravity description. The second, fluxbrane inflation, is a stringy version of D-term hybrid inflation. Both proposals rely on the fact that D7-brane coordinates enjoy a shift-symmetric Kahler potential at large complex structure of the Calabi-Yau threefold, making them naturally lighter than other fields. This shift symmetry is inherited from the mirror-dual Type IIA Wilson line on a D6-brane at large volume. The inflaton mass can be provided by a tree-level term in the flux superpotential. It induces a monodromy and, if tuned to a sufficiently small value, can give rise to a large-field model of inflation. Alternatively, by a sensible flux choice one can completely avoid a tree-level mass term, in which case the inflaton potential is induced via loop corrections. The positive vacuum energy can then be provided by a D-term, leading to a small-field model of hybrid natural inflation. In the present paper, we continue to develop a detailed understanding of the D7-brane moduli space focusing among others on shift-symmetry-preserving flux choices, flux-induced superpotential in Type IIB/F-theory language, and loop corrections. While the inflationary applications represent our main physics motivation, we expect that some of our findings will be useful for other phenomenological issues involving 7-branes in Type IIB/F-theory constructions.

The $Q_y$ of 3.6-6.3 detected $e^{-}/\mbox{keV}$, for applied electric fields in the range 240--2130 V/cm, is encouraging for the use of this detector medium to search for the signals from hypothetical dark matter particle interactions and from coherent elastic neutrino nucleus scattering. A significant dependence of $Q_y$ on the applied electric field is observed and explained in the context of ion recombination.

description: The so-called regime III of the a_2^{(2)} Izergin-Korepin 19-vertex model has defied understanding for many years. We show in this paper that its continuum limit involves in fact a non compact conformal field theory (the so-called Witten Euclidian black hole CFT), which leads to a continuous spectrum of critical exponents, as well as very strong corrections to scaling. Detailed numerical evidence based on the Bethe ansatz analysis is presented, involving in particular the observation of discrete states in the spectrum, in full agreement with the string theory prediction for the black hole CFT. Our results have important consequences for the physics of the O(n) model, which will be discussed elsewhere.

description: Hybrid-kinetic numerical simulations of firehose and mirror instabilities in a collisionless plasma are performed in which pressure anisotropy is driven as the magnetic field is changed by a persistent linear shear $S$. For a decreasing field, it is found that mostly oblique firehose fluctuations grow at ion Larmor scales and saturate with energies $\sim$$S^{1/2}$; the pressure anisotropy is pinned at the stability threshold by particle scattering off microscale fluctuations. In contrast, nonlinear mirror fluctuations are large compared to the ion Larmor scale and grow secularly in time; marginality is maintained by an increasing population of resonant particles trapped in magnetic mirrors. After one shear time, saturated order-unity magnetic mirrors are formed and particles scatter off their sharp edges. Both instabilities drive sub-ion-Larmor--scale fluctuations, which appear to be kinetic-Alfvén-wave turbulence. Our results impact theories of momentum and heat transport in astrophysical and space plasmas, in which the stretching of a magnetic field by shear is a generic process.

description: We derive the rotation-vibration spectrum of a 4-alpha configuration with tetrahedral symmetry, T_d, and show evidence for the occurrence of this symmetry in the low-lying spectrum of 16O. All vibrational states with A, E and F symmetry appear to have been observed, as well as the rotational bands with L(P)=0(+), 3(-), 4(+), 6(+) on the A states, and part of the rotational bands built on the E, F states. We derive analytic expressions for the form factors and B(EL) values of the ground state rotational band and show that the measured values support the tetrahedral symmetry of this band.

description: Charge carriers moving at the speed of light along a straight, superconducting cosmic string carry with them a logarithmically divergent slab of electromagnetic field energy. Thus no finite local input can induce a current that travels unimpeded to infinity. Rather, electromagnetic back-reaction must damp this current asymptotically to nothing. We compute this back-reaction and find that the electromagnetic fields and currents decline exactly as rapidly as necessary to prevent a divergence. We briefly discuss the corresponding gravitational situation.

description: In this work we study the diffractive photoproduction of $J/Ψ$ in proton-proton, proton - nucleus and nucleus - nucleus collisions at LHC energies using the color dipole formalism and different models for the forward dipole - target scattering amplitude. Our goal is to estimate the theoretical uncertainty present in the current predictions in the literature. Our results are compared with the experimental data and predictions for higher energies are presented.

Carbon and Nitrogen as Regulators of Algal Growth in Treated Sewage

description: Abstract:
Continuous flow algal cultures were grown under three different growth conditions using secondary sewage treatment plant effluent as the growth medium. The only variable within each run was the hydraulic residence time. The concentrations of growth regulating nutrients were varied between the runs so comparisons of the algal mass, composition, nutrient uptake, and genera could be made. The importance of CO2 availability for algal growth was also studied. A kinetic theory which based algal growth on cellular nutrient concentration was verified. The second phase of the study was a batch culture study in which the same growth medium was used as in Phase 1. The objective of Phase 2 was to investigate significant similarities and differences between continuous and batch culture growth under otherwise similar growth conditions.
Carbon dioxide enriched conditions produced as much as ten times the algal mass as CO2 deficient conditions. Algal blooms dominated by blue-green algae were found to be the result of a successional change from green to blue-green algae under CO2 enriched, nitrogen limited conditions. In the batch culture study algae exhibited a luxuriant nitrogen uptake.

description: We report on a seven-dimensional generator coordinate calculation in the two deformation parameters $β$ and $γ$ together with projection on three-dimensional angular momentum and two particle numbers for the low-lying states in $^{76}$Kr. These calculations are based on covariant density functional theory. Excellent agreement is found with the data for the spectrum and the electric multipole transition strengths. This answers the important question of dynamic correlations and triaxiality in a fully microscopic way. We find that triaxial configurations dominate both the ground state and the quasi $γ$-band. This yields a different picture from the simple interpretation in terms of "coexistence of a prolate ground state with an oblate low-lying excited state", which is based on the measured sign of spectroscopic quadrupole moments. This study also provides for the first time a benchmark for the collective Hamiltonian in five dimensions. Moreover, we point out that the staggering phase of the $γ$-band is not a safe signature for rigid triaxiality of the low-energy structure.

description: Given the long-term nature of the COVID-19 pandemic, it is imperative we identify and address the needs of mental health care providers as they serve their communities during the pandemic. This article describes the psychological burnout, trauma, and exhaustion experienced by mental health providers in the United States, as well as the meaning derived from being part of the COVID-19 public health response. Based on these findings, we offer recommendations to support mental health care providers to prevent and address burnout, promote personal wellness, and foster sustainable work practices.
description: The SARS-CoV-2 (COVID-19) pandemic has placed a tremendous strain on health care providers. Although there is a burgeoning body of literature on how COVID-19 has impacted frontline health care workers (i.e., providers treating COVID-19 patients), little attention has been dedicated to second-line workers (i.e., providers treating the mental health of people impacted by COVID-19). In this article, we present findings from a thematic analysis of open-text responses (n = 136) examining how COVID-19 shaped both the well-being of second-line workers, specifically mental health providers, as well as their clinical work in the early months of the COVID-19 pandemic in the United States. Results indicated that mental health providers were experiencing significant COVID-19-related burnout and poor physical and mental health outcomes. Participants described diminished negative effects on the quality of their clinical care from the burnout and trauma associated with COVID-19. Many also demonstrated resilience, identifying the duality of both negative (e.g., exhaustion) and positive (e.g., pride in helping others) meaning derived from their second-line work experiences. We conclude with recommendations for preventing and addressing burnout among mental health professionals in the era of COVID-19 and subsequent health emergencies.
Be YOU!: A collaborative effort to address minority stress for LGBTQ + youth in school settings

description: LGBTQ youth often experience unsafe school climates and are at greater risk for compromised mental health relative to their heterosexual and cisgender peers. The psychological mediation model posits that these health inequities are produced by minority stress, which operates through several key mechanisms: rumination, emotion regulation, and coping. Efforts toward designing social services that might address these mechanisms, and thus improve LGBTQ youth well-being, are limited. Informed by empirical research and therapeutic practices, Be YOU! was conceived as a school-based empowerment program that provides LGBTQ youth with an accessible, safe space where they build skills to reduce rumination and promote emotion regulation and coping strategies for dealing with minority stressors. Developed collaboratively among a local LGBTQ youth center, a local school-based community organization, and university researchers, the Be YOU! partnership effectively circumvented barriers to accessing social services for LGBTQ youth. Findings from the pilot program evaluation showed that youth participation was associated with increased emotion regulation and decreased rumination. The practical impact on and positive feedback from LGBTQ youth suggest that there are measurable benefits and longterm promise in strategic multi-sector partnerships that address social services needs of LGBTQ youth and strengthen their ability to navigate minority stress.

description: Drawing on social exchange theory, this study investigates the mechanism of felt obligation underpinning the link between three key forms of perceived support (organization, supervisor, and team) and three key frontline employee work outcomes. The study also examines felt obligation - employee work outcomes relationships under the boundary condition of perceived fairness in reward allocation to explore if felt obligation preserves employee support despite unfair outcomes. Data obtained from 347 frontline employees in a call center organization largely support our hypotheses. Our findings demonstrate that perceived supervisor and team support exert a greater influence on felt obligation than the commonly investigated perceived organizational support. Our findings underscore the importance of felt obligation as an influential social exchange force that stimulates affective commitment and reduces turnover intentions of employees even under conditions when fairness in reward allocation is perceived to be lower. Felt obligation also influences service recovery performance positively.

description: The precipitation of energetic neutral atoms, produced through charge exchange collisions between solar wind ions and thermal atmospheric gases, is investigated for the Martian atmosphere. Connections between parameters of precipitating fast ions and resulting escape fluxes, altitude-dependent energy distributions of fast atoms and their coefficients of reflection from the Mars atmosphere, are established using accurate cross sections in Monte Carlo simulations. Distributions of secondary hot atoms and molecules, induced by precipitating particles, have been obtained and applied for computations of the non-thermal escape fluxes. A new collisional database on accurate energy-angular dependent cross sections, required for description of the energy-momentum transfer in collisions of precipitating particles and production of non-thermal atmospheric atoms and molecules, is reported with analytic fitting equations. 3D Monte Carlo simulations with accurate energy-angular dependent cross sections have been carried out to track large ensembles of energetic atoms in a time-dependent manner as they propagate into the Martian atmosphere and transfer their energy to the ambient atoms and molecules. Results of the Monte Carlo simulations on the energy-deposition altitude profiles, reflection coefficients, and time-dependent atmospheric heating, obtained for the isotropic hard sphere and anisotropic quantum cross sections, are compared. Atmospheric heating rates, thermalization depths, altitude profiles of production rates, energy distributions of secondary hot atoms and molecules, and induced escape fluxes have been determined.
