description: With Bayesian statistics, we investigate the full parameter space of the constrained "next-to-minimal" supersymmetric Standard Model (CNMSSM) with naturalness priors, which were derived in a previous work. In the past, most Bayesian analyses of the CNMSSM ignored naturalness of the electroweak (EW) scale by making prejudicial assumptions for parameters defined at the EW scale. We test the CNMSSM against the CMSSM with Bayesian evidence, which, with naturalness priors, incorporates a penalty for fine-tuning of the EW scale. With the evidence, we measure credibility with respect to all measurements, including the EW scale and LHC direct searches. We find that the evidence in favor of the CNMSSM versus the CMSSM is "positive" to "strong" but that if one ignores the $μ$-problem, the evidence is "barely worth mentioning" to "positive." The $μ$-problem significantly influences our findings. Unless one considers the $μ$-problem, the evidence in favor of the CNMSSM versus the CMSSM is at best "positive," which is two grades below "very strong." We, furthermore, identify the most probable regions of the CMSSM and CNMSSM parameter spaces and examine prospects for future discovery at hadron colliders.

title: Metabolomics profiling of Gilbert syndrome subjects
Creators: name: Tran, Thi Lan Vi
Year: 2021

description: Ziel dieser Masterarbeit war es mittels Kernspinresonanzspektroskopie (NMR) das metabolische Profil von Personen mit Gilbert Syndrom (GS) zu erforschen. Methodik: Dafür wurde das Serum von 56 Personen mit GS und 56 Personen ohne GS analysiert und verglichen. Alle Studienteilnehmer haben vor der Probeentnahme über Nacht gefastet und waren nüchtern. Für die statistischen Analysen wurden die Programme SIMCA und SAS herangezogen, um die Principal Component Analysis (PCA), die Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA), den Paardifferenzentest and den Wilcoxon-Mann-Whitney-Test durchzuführen. Ergebnisse: Es konnte festgestellt werden, dass die Metabolite Acetylcarnitin (p=0,0003), Ketonkörper (3-Hydroxybutyrate (p=0,00001), Aceton (p=0,00001) und Acetoacetat (p=0,0007), Zitronensäure (p=0,0002), 2-Oxo-isocapronsäure (p=0,0006), Trimethylamin (p=0,00001) und Acetylglycin (p=0,0002) im Serum der Personen mit GS signifikant höher waren als die der Kontrollgruppe. Schlussfolgerung: Höhere Konzentrationen von Ketonkörpern, Zitronensäure und Acetylcarnitin bei Personen mit GS, im Vergleich zur Kontrollgruppe, weisen auf einen verstärkten Lipidstoffwechsel hin, insbesondere während dem Katabolismus.

description: We study the finite temperature Hartree-Fock-BCS approximation for selected stable Sn nuclei with zero-range Skyrme forces. Hartree Fock BCS approximation allows for a straightforward interpretation of the results since it involves u and v's which are not matrices as in HFB. Pairing transitions from superfluid to the normal state are studied with respect to the temperature. The temperature dependence of the nuclear radii and neutron skin are also analyzed. An increase of proton and neutron radii is obtained in neutron rich nuclei especially above the critical temperature. Using different Skyrme energy functionals, it is found that the correlation between the effective mass in symmetric nuclear matter and the critical temperature depends on the pairing prescription. The temperature dependence of the nucleon effective mass is also investigated, showing that proton and neutron effective masses display different behavior below and above the critical temperature, due to the small temperature dependence of the density.

description: Explaining the evolution of cooperation in the strong altruism scenario, where a cooperator does not benefit from her contribution to the public goods, is a challenging problem that requires positive assortment among cooperators (i.e., cooperators must tend to associate with other cooperators) or punishment of defectors. The need for these drastic measures stems from the analysis of a group selection model of temporarily formed random groups introduced by Hamilton nearly fifty years ago to describe the fate of altruistic behavior in a population. Challenging conventional wisdom, we show analytically here that strong altruism evolves in Hamilton's original model in the case of biparental sexual reproduction. Moreover, when the cost of cooperation is small and the amplified contribution shared by group members is large, cooperation is the only stable strategy in equilibrium. Thus, our results provide a solution to the `problem of origination' of strong altruism, i.e. how cooperation can take off from an initial low frequency of cooperators. We discuss a possible reassessment of cooperation in cases of viral co-infection, as cooperation may even be favored in situations where the prisoner's dilemma applies.

Beyond "the Artist's Wife:" Women, Artist-Couple Marriage and the Exhibition Experience in Postwar Canada
Creators: Mastin, Catharine Margaret
Publisher: name: University of Alberta Library
Year: 2012

When art critic Lucy Lippard named “the artist’s wife” to be a socially-assigned identity for female artists in the early 1970s, she understood some of the significance of women’s companionship status. This dissertation considers how “the artist’s wife” was a diverse and hierarchical problem for six female artists during their efforts to access Canada’s postwar exhibition market. Joyce Wieland of Toronto, Ontario, Marion Nicoll of Calgary, Alberta, Mary Pratt of St. John’s, Newfoundland, and Kenojuak Ashevak of Cape Dorset, Nunavut all experienced this social phenomenon differently. Because the two studios of Wieland and Pratt were combined with domestic life they were also dubbed “kitchen artists.” As Marion Nicoll learned, it took much conviction to pursue an art practice focused on abstract painting in traditional institutional and marital contexts. The category “Eskimo” added racial difference to Kenojuak’s creative and marital identities. Frances Loring and Florence Wyle of Toronto were persistently called “the Girls,” an identity that underscored their non-compliance with heterosexual marriage.

Using feminist theories of sexual difference and representation, and intersecting the traditionally distinct fields of history and art history, this study illuminates that the female artist’s companionship status mattered much more than has been historically understood. These artists’ experiences provide opportunity to reflect on curatorial practice and subject representation and expose that the solo exhibition cannot be fully separated from the artist-couple exhibition when studying the female artist’s exhibition history. Their experiences also make visible that gender and female artist identities, including the category “woman artist,” are important when studying the female artist in postwar North American art and marriage histories if the social conditions of women’s art production are to be fully understood.

description: The tilt-to-length coupling during the LISA Pathfinder mission has been numerically and analytically modeled for particular timespans. In this work, we investigate the long-term stability of the coupling coefficients of this noise. We show that they drifted slowly (by 1\,$μ$m/rad and 6$\times10^{-6}$ in 100 days) and strongly correlated to temperature changes within the satellite (8\,$μ$m/rad/K and 30$\times10^{-6}$/K). Based on analytical TTL coupling models, we attribute the temperature-driven coupling changes to rotations of the test masses and small distortions in the optical setup. Particularly, we show that LISA Pathfinder's optical baseplate was bent during the cooldown experiment, which started in late 2016 and lasted several months.

description:  

 

The aim of this paper is to analyze the interrelationships between the burnout and different psychosocial variables to which the grassroots football referee is exposed, in particular, associated with the influence of the environment and the level of verbal and physical aggression. To this end, a questionnaire was developed, consisting of items from the Maslach Burnout Inventory-General Survey (MBI-GS) and various self-constructed items designed to find out these psychosocial variables. First, a study of the structure of the form was carried out. Second, a structural equation model was designed in order to test the causal relationship between the variables under consideration. The results obtained point to the validity of the proposed theoretical model. It is recommended to initiate training programs for this group aimed at strengthening personal coping and social support strategies, which can help minimize the evolution of this syndrome.

description: We propose a reconstruction of general bulk surfaces in any dimension in terms of the differential entropy in the boundary field theory. In particular, we extend the proof of Headrick et al. to calculate the area of a general class of surfaces, which have a 1-parameter foliation over a closed manifold. The area can be written in terms of extremal surfaces whose boundaries lie on ring-like regions in the field theory. We discuss when this construction has a description in terms of spatial entanglement entropy and suggest lessons for a more complete and covariant approach.

description: There is now a large consensus that the current epoch of the Cosmic Star Formation History (CSFH) is dominated by low mass galaxies while the most active phase at 1~1, the most IR-luminous galaxies (LIRGs and ULIRGs) are preferentially located in groups, and this is consistent with a reversal of the star-formation rate vs .density anti-correlation observed in the nearby Universe. At these redshifts, group galaxies contribute 60-80% of the CSFH, i.e. much more than at lower redshifts. Below z~1, the comoving number and SFR densities of IR-emitting galaxies in groups decline significantly faster than those of all IR-emitting galaxies. Our results are consistent with a "halo downsizing" scenario and highlight the significant role of "environment" quenching in shaping the CSFH.

The Context of Immigrant Reception in the American South
Creators: name: Maggio, Christopher
Publisher: name: University of Illinois at Chicago
Year: 2023
Subjects: Uncategorized

description: Past research has shown the Southern United States to have more conservative immigration attitudes compared to more established immigrant destination states. However, it is unclear whether or not the places that immigrants have arrived share these conservative attitudes and how this impacts the reception of immigrant groups. Analyzing the Cooperative Congressional Election Study, I find that U.S.-born White attitudes toward immigration are less conservative in zip codes where immigrant-origin groups in the South are most likely to live, often by substantial margins. This indicates that immigrant-origin groups in the South are likely to encounter Southern Whites with a more liberal orientation than Southern Whites more generally. The implications for how these attitudes compare to established immigrant destination states and counties are addressed in detail, as are Southern Black attitudes toward immigration. Regardless, on various questions approximating racial experience/understanding, immigrant-origin groups in the South do not report more negative feelings than those in established destinations and report more positive feelings in some cases, although these results could also indicate a lower awareness of racial issues. Overall, these findings point to a context of reception in the South that is likely more positive than past research on Southern immigration attitudes has implied.

description: Large Language Models (LLMs) have showcased their remarkable capabilities in diverse domains, encompassing natural language understanding, translation, and even code generation. The potential for LLMs to generate harmful content is a significant concern. This risk necessitates rigorous testing and comprehensive evaluation of LLMs to ensure safe and responsible use. However, extensive testing of LLMs requires substantial computational resources, making it an expensive endeavor. Therefore, exploring cost-saving strategies during the testing phase is crucial to balance the need for thorough evaluation with the constraints of resource availability. To address this, our approach begins by transferring the moderation knowledge from an LLM to a small model. Subsequently, we deploy two distinct strategies for generating malicious queries: one based on a syntax tree approach, and the other leveraging an LLM-based method. Finally, our approach incorporates a sequential filter-test process designed to identify test cases that are prone to eliciting toxic responses. Our research evaluated the efficacy of DistillSeq across four LLMs: GPT-3.5, GPT-4.0, Vicuna-13B, and Llama-13B. In the absence of DistillSeq, the observed attack success rates on these LLMs stood at 31.5% for GPT-3.5, 21.4% for GPT-4.0, 28.3% for Vicuna-13B, and 30.9% for Llama-13B. However, upon the application of DistillSeq, these success rates notably increased to 58.5%, 50.7%, 52.5%, and 54.4%, respectively. This translated to an average escalation in attack success rate by a factor of 93.0% when compared to scenarios without the use of DistillSeq. Such findings highlight the significant enhancement DistillSeq offers in terms of reducing the time and resource investment required for effectively testing LLMs.

description: The possibility of neutron pairing in the $^1S_0$ channel is studied for dense neutron matter in a vicinity of the $π^0$ condensation point. The $^1S_0$ pairing gap $Δ$ is shown to occur in a model with a pairing force induced by the exchange of a soft neutral pionic mode. The soft pion induced potential $V_π(r)$ is characterized by an attenuating oscillatory behavior in coordinate space, while in momentum space all $S$-wave matrix elements $V_π(p,p')$ are positive. The solution of the gap equation reveals strong momentum dependence.

title: Numerische Simulation der elektrischen Feldverteilung in Hochspannungs-Gleichstromkabelsystemen unter Berücksichtigung von nichtlinearen Effekten
Creators: name: Jörgens, Christoph
Publisher: name: Bergische Universität Wuppertal

description: Durch den Ausbau des Stromnetzes und die steigende Nutzung von erneuerbaren Energien rückt die Hochspannungs-Gleichstrom-Übertragung (HGÜ) immer mehr in den Fokus, da ein Transport von hohen Leistungen über große Distanzen nur mit dieser Technologie wirtschaftlich ist. Den verwendeten Isolationsmaterialien in den einzelnen HGÜ-Betriebsmitteln kommt dabei eine besondere Rolle zu, da die elektrische Leitfähigkeit eine nichtlineare Abhängigkeit von der Temperatur und der elektrischen Feldstärke zeigt. Aufgrund der konstanten Betriebsspannung kommt es daher zur Akkumulation von Raumladungen. Diese führen letztlich zu einem langsam zeit-veränderlichen elektrischen Feld, wobei die Ladungsansammlungen zu lokalen Feldüberhöhungen und einer Schädigung des Isolierstoffes führen können.
 Die vorliegende Arbeit befasst sich mit der numerischen Simulation der elektrischen Feldverteilung in Hochspannungs-Gleichstromkabelsystemen unter Berücksichtigung von Raumladungseffekten. Neben einer mikroskopischen Betrachtung wird der Ladungstransport auch makroskopisch, mittels einer temperatur- und feldstärkeabhängigen Leitfähigkeit modelliert. Die erhaltenden Simulationsergebnisse werden gegen Messungen und analytische Approximationen verglichen. Mittels geeigneter Weiter-entwicklungen der Leitfähigkeitsmodelle wird die Differenz zwischen Simulation und Messung, im Vergleich zu gängigen Modellen, verringert. Neben einer physikalischen Betrachtung der Isolierstoffe ist ein weiterer Aspekt der Arbeit die Weiterentwicklung von numerischen Berechnungsverfahren. So werden zum einen unterschiedliche Berechnungsansätze, mit Blick auf die Genauigkeit und die Berechnungszeit, gegeneinander verglichen. Zudem werden gekoppelte elektro-thermische Simulationen von Kabeln, zusammen mit dessen Umgebung, präsentiert und Vereinfachungen der elektrischen Feldberechnung untersucht. Zuletzt wird der Spezialfall eines elektro-quasistatischen Feldes vorgestellt. Hervorgerufen durch die Bewegung der Wassermoleküle unter einem angelegten Gleichfeld, kommt es in der Nähe von Erdelektroden zum Effekt der Elektro-Osmose. Dabei kommt es nicht zu einer Akkumulation von Raumladungen, sondern die zeitliche Veränderung des Feldes entsteht durch die Abhängigkeit der Bodenleitfähigkeit von der Feuchtigkeit.

description: Als Beitrag zum Forschungsfeld des Entrepreneurship wird in dieser Arbeit untersucht, welchen Einfluss das individuelle Vorwissen bzw. die individuellen Erfahrungswerte sowie die persönliche Motivationslage eines Entrepreneurs auf die Ideenfindung für die eigene Unternehmensgründung hat, und inwiefern sich Einfach- und Mehrfachgründer dabei unterscheiden. Für die Untersuchung des Sachverhaltes wird zunächst die einschlägige Literatur ausführlich beleuchtet. Anschließend erfolgt die Erhebung und Auswertung von Primärdaten. Es wurden 18 Interviews mit Einfach- und Mehrfachgründern geführt und die Sachverhalte anhand der qualitativen Inhaltsanalyse untersucht. Es wird eine Typologie erstellt und vier polythetische Typen aus den Daten abgeleitet. Die Typen werden in einem zweidimensionalen Merkmalsraum anhand der Gründungshäufigkeit (Einfach- vs. Mehrfachgründer), der Gründungsmotivation (entrepreneurship-inhärent vs. entrepreneurship-kohärent) und der Herkunft der Gründungsidee (schlüssig vs. erratisch) unterschieden. Die erstmaligen Gründer werden anhand ihrer Gründungsmotivation in Pragmatiker und Gläubige unterteilt. Die Ideenquelle für die Pragmatiker ist die vorherige Arbeitsstelle. Die Ideenquelle für die Gläubigen ist das familiäre bzw. nahe persönliche Umfeld. Die Gruppe der habituellen Gründer werden ebenfalls anhand ihrer Gründungsmotivation in die Getriebenen und die Stringenten unterteilt. Für die Ideenquelle der Getriebenen lässt sich kein gemeinsamer Nenner ableiten: sie haben ein entrepreneurship-kohärentes Gründungsmotiv und ein thematisch erratisches Gründungsverhalten und bei der Ideenherkunft keine Gemeinsamkeit. Die Stringenten erhalten die Idee für ihre erste Gründung aus der vorherigen Arbeitsstelle, welche sie jedoch im Gegensatz zu den Pragmatikern mit der Gründung thematisch weiterentwickeln. Die Ideen für die weiteren Gründungen der Stringenten ergeben sich aus der ersten Gründung, bspw. durch die Weiterentwicklung eines Themas oder durch die Umsetzung eines Kundenwunsches. Nach der ausführlichen (Zusammenhangs-)analyse der verschiedenen Typen erfolgt die Ableitung von Hypothesen aus dem Datenmaterial sowie Vorschlägen zur Operationalisierung. Die Arbeit schließt mit weiterführenden Gedanken zu Implikationen für die Entrepreneurship- Forschung und -Praxis sowie Limitationen und weiteren sich daraus ergebenden Forschungsaspekten.

Especially Sub-Saharan Africa can benefit from it enabling an increased access to clean energy through utilizing its beneficial conditions for renewable energies. However, developing green hydrogen strategies for Sub-Saharan Africa requires highly detailed and consistent information ranging from technical, environmental, economic, and social dimensions, which is currently lacking in literature. Therefore, this paper provides a comprehensive novel approach embedding the required range of disciplines to analyze green hydrogen cost-potentials in Sub-Saharan Africa. This approach stretches from a dedicated land eligibility based on local preferences, a location specific renewable energy simulation, locally derived sustainable groundwater limitations under climate change, an optimization of local hydrogen energy systems, and a socio-economic indicator-based impact analysis. The capability of the approach is shown for case study regions in Sub-Saharan Africa highlighting the need for a unified, interdisciplinary approach.

Black Holes, Entropies, and Semiclassical Spacetime in Quantum Gravity

description: We present a coherent picture of the quantum mechanics of black holes. The picture does not require the introduction of any drastically new physical effect beyond what is already known; it arises mostly from synthesizing and (re)interpreting existing results in appropriate manners. We identify the Bekenstein-Hawking entropy as the entropy associated with coarse-graining performed to obtain semiclassical field theory from a fundamental microscopic theory of quantum gravity. This clarifies the issues around the unitary evolution, the existence of the interior spacetime, and the thermodynamic nature in black hole physics--any result in semiclassical field theory is a statement about the maximally mixed ensemble of microscopic quantum states consistent with the specified background, within the precision allowed by quantum mechanics. We present a detailed analysis of information transfer in Hawking emission and black hole mining processes, clarifying what aspects of the underlying dynamics are (not) visible in semiclassical field theory. We also discuss relations between the black hole entropy and the entanglement entropy across the horizon. We then extend our discussions to more general contexts in quantum gravity. The subjects include extensions to de Sitter and Minkowski spaces and implications for complementarity and cosmology, especially the eternally inflating multiverse.

title: Auto-generated structured meshes for evolving domains
Creators: name: Hahn, Camilla
Publisher: name: Bergische Universität Wuppertal
Year: 2021

description: In this thesis we present an approach to auto-generate highly structured meshes for applications where the domain changes over time. Especially in the area of PDE-constrained shape optimization, a key bottle neck in the computation is the generation of stable meshes in each iteration. The proposed approach possesses the advantages of structured meshes and is still capable of resolving boundaries accurately. Through the specific structure of the meshes, computational cost is reduced not only while generating the mesh but in the assembly of the governing linear system of equations as well. Additionally, we present an approach to apply Krylov subspace recycling to evolving domains, a state of the art method to solve large sparse linear systems of equations. We present results in two and three dimensions and how the meshes evolve in a gradient-based shape optimization setting.

description: Highly r-process-enhanced stars are rare and usually metal-poor ([Fe/H] < - 1.0), and mainly populate the Milky Way halo and dwarf galaxies. This study presents the discovery of a relatively bright (V = 12.72), highly r-process-enhanced (r-II) star ([Eu/Fe] = +1.32, [Ba/Eu] = - 0.95), LAMOST J020632.21 + 494127.9. This star was selected from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) medium-resolution (R ~ 7500) spectroscopic survey; follow-up high-resolution (R ~ 25,000) observations were conducted with the High Optical Resolution Spectrograph (HORuS) installed on the Gran Telescopio Canarias (GTC). The stellar parameters (${T_{\rm eff}}$ = 4130 K, $\rm log\,g $ = 1.52, $ \rm[Fe/H] $ = $ - $0.54, $ξ$ = 1.80 $ \rm{km\,{s^{-1}}} $) have been inferred taking into account non-local thermodynamic equilibrium (NLTE) effects. The abundances of [Ce/Fe], [Pr/Fe], and [Nd/Fe] are +0.19, +0.65 and +0.64, respectively, relatively low compared to the Solar r-process pattern normalized to Eu. This star has a high metallicity ([Fe/H] = - 0.54) compared to most other highly r-process-enhanced stars, and has the highest measured abundance ratio of Eu to H ([Eu/H] = +0.78). It is classified as a thin-disk star based on its kinematics, and does not appear to belong to any known stream or dwarf galaxy.

Many-Body Localization Transition in Random Quantum Spin Chains with Long-Range Interactions

description: While there are well established methods to study delocalization transitions of single particles in random systems, it remains a challenging problem how to characterize many body delocalization transitions. Here, we use a generalized real-space renormalization group technique to study the anisotropic Heisenberg model with long-range interactions, decaying with a power $α$, which are generated by placing spins at random positions along the chain. This method permits a large-scale finite-size scaling analysis. We examine the full distribution function of the excitation energy gap from the ground state and observe a crossover with decreasing $α$. At $α_c$ the full distribution coincides with a critical function. Thereby, we find strong evidence for the existence of a many body localization transition in disordered antiferromagnetic spin chains with long range interactions.

Principals' attitudes about school psychological services
Creators: name: Greene, Laura Lynn
Publisher: name: No Publisher Supplied
Year: 2010

description: The literature in the field of school psychology suggests that the role of the school psychologist has been primarily as a person who conducts assessments for the special education population but that school psychologists desire to be engaged in additional services, such as prevention and direct intervention. Influences on the role of school psychologist may include: perceptions of consumer groups, the power and influence of the school principal and special education legislation. A qualitative study was conducted to obtain the perceptions of principals, as an individual consumer group, about current and desired school psychological services, as well as potential barriers to expanding the role. Semi-structured interviews were conducted with ten elementary school principals in Central/Northern New Jersey and the data were analyzed using Interpretative Phenomenological Analysis and Classical Content Analysis. Results suggested that principals perceived assessment to be the primary activity of the school psychologist and that many school psychologists were also involved in consultative activities, or served as a resource to staff and families. Most of the principals in this study expressed a desire for additional services, such as providing training to parents and staff, as well as having the school psychologist have more direct contact with students. The envisioned role was also seen as preventative rather than reactive with increased flexibility and increased visibility in the school. The perceived barriers to expanding the role of the school psychologist that were reported were time and financial constraints, as well as legislation. Principals in this study did not view themselves as being a critical influence in defining the role of the school psychologist. They suggested that school psychologists make a plan and approach the administration with recommendations of how to expand their services in the iii school. In order to facilitate this, training programs could place a greater emphasis on preparing school psychologists for the role of providing training and psycho-education, as well as preparing them for collaboration with administrators and other stakeholders in the school.

description: Trichoderma is a cosmopolitan genus with diverse lifestyles and nutritional modes, including mycotrophy, saprophytism, and endophytism. Previous research has reported greater metabolic gene repertoires in endophytic fungal species compared to closely-related non-endophytes. However, the extent of this ecological trend and its underlying mechanisms are unclear. Some endophytic fungi may also be mycotrophs and have one or more mycoparasitism mechanisms. Mycotrophic endophytes are prominent in certain genera like Trichoderma, therefore, the mechanisms that enable these fungi to colonize both living plants and fungi may be the result of expanded metabolic gene repertoires. Our objective was to determine what, if any, genomic features are overrepresented in endophytic fungi genomes in order to undercover the genomic underpinning of the fungal endophytic lifestyle. Here we compared metabolic gene cluster and mycoparasitism gene diversity across a dataset of thirty-eight Trichoderma genomes representing the full breadth of environmental Trichoderma's diverse lifestyles and nutritional modes. We generated four new Trichoderma endophyticum genomes to improve the sampling of endophytic isolates from this genus. As predicted, endophytic Trichoderma genomes contained, on average, more total biosynthetic and degradative gene clusters than non-endophytic isolates, suggesting that the ability to create/modify a diversity of metabolites potential is beneficial or necessary to the endophytic fungi. Still, once the phylogenetic signal was taken into consideration, no particular class of metabolic gene cluster was independently associated with the Trichoderma endophytic lifestyle. Several mycoparasitism genes, but no chitinase genes, were associated with endophytic Trichoderma genomes. Most genomic differences between Trichoderma lifestyles and nutritional modes are difficult to disentangle from phylogenetic divergences among species, suggesting that Trichoderma genomes may be particularly well-equipped for lifestyle plasticity. We also consider the role of endophytism in diversifying secondary metabolism after identifying the horizontal transfer of the ergot alkaloid gene cluster to Trichoderma.
