description: The human brain is considered the most complex organ. The early stages of brain development may perhaps be the most crucial time in the brain's formation as neural tube defects occur very early in pregnancy if the neural tube does not close completely. I am interested in the early events that shape the central nervous system, namely: the cell behaviors that shape the neural tube, the precursor of the brain and spinal cord. A signaling pathway called planar cell polarity (PCP) mediates proper cellular behaviors in many tissues, including the developing neural tube. There is an ongoing controversy as to whether cilia mediate PCP signaling during neural tube formation and other developmental processes. Evidence that ciliary proteins are required for neural tube formation stems from the observation that disruption of multiple genes implicated in ciliogenesis results in delayed or blocked neural tube formation. Nevertheless, whether impaired ciliogenesis prevents proper PCP signaling remains unknown. Using a bioinformatics approach, the Kann laboratory recently identified the novel PCP pathway component Nucleoredoxin (Nxn) as a putative bindig partner of the ciliary protein IFT88. Nxn therefore provides a molecular entry point with which to explore the interaction between cilia and PCP signaling. My thesis work centers on validating Nxn as an IFT88 binding partner and testing the predictions that depletion of Nxn should cause similar neural tube defects as those observed in PCP mutants and Nxn should localize to cilia where IFT88 is also enriched. This research lays the framework for future studies on mechanisms of cilia-PCP interactions.

description: The Wnt signaling pathway is one of the key extracellular pathways involved in many developmental processes in vertebrates and invertebrates. In the nematode C. elegans, the two Wnt pathways named the Wnt/BAR-1 canonical (WBC) pathway and the Wnt/?-catenin asymmetry (WBA) pathway function in cell fate specification, polarity and migration. We and others have shown that the WBC pathway functions in the specification of the vulval precursor cells (VPCs) that form the hermaphrodite vulva, and the WBA pathway functions in the specification of epithelial seam cells during their larval asymmetric stem cell-like divisions. My research project has focused on the identification of Wnt signaling targets functioning in the VPCs and seam cells using microarray analysis.  The Wnt pathway was over-activated in worms using a heat shock inducible stable variant of BAR-1/?-catenin, and under-activated using a dominant negative variant of  POP-1/TCF. The transcript pools from the VPCs and seam cells were enriched by the `mRNA tagging' method and I used microarray analysis to identify 240 putative Wnt pathway targets showing an average fold change of ≥ 1.5 in the Wnt pathway over-activation samples compared to the under-activation samples. Of these, expression analysis and phenotypic characterization was conducted for 50 genes. I found 29 genes are expressed in the seam cells, hypodermis and/or vulval cells during larval development. RNA interference and mutant analysis revealed five genes with defects in terminal seam cell number. This work has also uncovered a previously unexplored role of Wnt signaling and of eight putative Wnt targets in influencing the lateral fusion of differentiated seam cells, and formation of the cuticular structure called alae. Additionally, 12 putative Wnt targets showed defects in vulval induction, differentiation and morphogenesis.  I have also identified the GATA transcription factor encoding genes egl-18 and elt-6, which are known embryonic regulators of seam cell specification, as putative Wnt targets in larval seam cells. Genetic and epistasis analysis suggests that these factors act reiteratively downstream of the Wnt pathway in specifying seam cell fate during larval asymmetric seam cell divisions, unraveling a novel connection between two important regulators of seam cell fate specification. Finally, I have defined for the first time, the L2/L3 larval transcriptome of the seam cells and VPCs. This work has filled a significant gap in our understanding of C. elegans Wnt targets functioning in seam cell and vulval development.
Avoidance of singularities in spherically symmetric charged dust

description: In spherically symmetric charged dust, just like in electrically neutral dust, two kinds of singularity may be present: the Big Bang/Crunch (BB/BC) singularity, and shell crossings. Quite unlike in neutral dust, the BB/BC singularity may be avoided. When the absolute value of the charge density r is everywhere small compared to the mass-energy density d (|r| < D = \sqrt{G} d / c^2), the conditions that allow the model to avoid the BB/BC singularity necessarily lead to shell crossings. There exist sets of initial conditions that allow us to avoid both singularities (when either |r| > D everywhere, or |r| = D at the center of symmetry while |r| < D elsewhere). In those cases, both kinds of singularity may be avoided for a sufficiently long period that a body of charged dust may go through the tunnel between the singularities in the maximally extended Reissner -- Nordstrom spacetime, to emerge into another asymptotically flat region. An explicit example of such a configuration is presented and discussed. It does not contradict any astrophysical constraints.

description: A recurring theme in the least squares approach to phylogenetics has been the discovery of elegant combinatorial formulas for the least squares estimates of edge lengths. These formulas have proved useful for the development of efficient algorithms, and have also been important for understanding connections among popular phylogeny algorithms. For example, the selection criterion of the neighbor-joining algorithm is now understood in terms of the combinatorial formulas of Pauplin for estimating tree length. We highlight a phylogenetically desirable property that weighted least squares methods should satisfy, and provide a complete characterization of methods that satisfy the property. The necessary and sufficient condition is a multiplicative four point condition that the the variance matrix needs to satisfy. The proof is based on the observation that the Lagrange multipliers in the proof of the Gauss--Markov theorem are tree-additive. Our results generalize and complete previous work on ordinary least squares, balanced minimum evolution and the taxon weighted variance model. They also provide a time optimal algorithm for computation.

description: The vorticity random field of turbulent flow is singled out as the main dynamical variable for the description of turbulence, and the evolution equation of the probability density function (PDF) of the vorticity field has been obtained. This PDF evolution equation is a mixed type partial differential equation (PDE) of second order which depends only on the conditional mean (first order) of the underlying turbulent flow, which is in contrast with Reynolds' mean flow equation which relies on a quadratic statistics. Therefore the new PDF PDE may provide new closure scheme based on the conditional linear statistics, and some of them will be described in the present paper too.

description: We investigate backgrounds of Type IIB string theory with null singularities and their duals proposed in hep-th/0602107. The dual theory is a deformed N=4 Yang-Mills theory in 3+1 dimensions with couplings dependent on a light-like direction. We concentrate on backgrounds which become AdS_5 x S^5 at early and late times and where the string coupling is bounded, vanishing at the singularity. Our main conclusion is that in these cases the dual gauge theory is nonsingular. We show this by arguing that there exists a complete set of gauge invariant observables in the dual gauge theory whose correlation functions are nonsingular at all times. The two-point correlator for some operators calculated in the gauge theory does not agree with the result from the bulk supergravity solution. However, the bulk calculation is invalid near the singularity where corrections to the supergravity approximation become important. We also obtain pp-waves which are suitable Penrose limits of this general class of solutions, and construct the Matrix Membrane theory which describes these pp-wave backgrounds.

description: Breast cancer is readily treatable at early stages; however few if any treatments exist for patients diagnosed with late stage metastatic disease. Because CD4+ T cells are crucial for long term immunologic memory and may prevent or eliminate dissemination of latent metastases, this thesis is focused on identifying novel immunogenic major histocompatibility class (MHC) II-restricted peptides that activate tumor-specific CD4+ T cells. MHC II cell-based vaccines (human breast cancer cells transduced with MHC II and costimulatory molecules) efficiently activate healthy donors' and breast cancer patients' CD4+ T cells, provided vaccines do not express chaperone protein Invariant chain (Ii). Therefore, it was hypothesized that in the absence of Ii, novel immunogenic MHC II-restricted peptides would be presented by tumor cells. To prove this hypothesis, MHC II-restricted peptides from Ii- vaccine cells and Ii+ tumor cells were sequenced using mass spectrometry-based peptidomics.  Four hundred and thirty peptides were identified, 92 of which were uniquely presented by Ii- MHC II cell-based vaccines. Seven of these peptides efficiently activated tumor-specific T cells from healthy donors and breast cancer patients. Therefore, these studies established that Ii regulates the peptide repertoire presented by MHC II+ tumor cells and identified peptides that are potential candidates for breast cancer vaccines. Most breast cancer patients are immune suppressed, and therefore may be restricted in their ability to respond to vaccine immunotherapy. Among the most potent mediators of tumor-induced immune suppression are myeloid-derived suppressor cells (MDSC). Heightened inflammation exacerbates MDSC accumulation and immune suppressive potency. To understand the mechanisms by which inflammation regulates MDSC, the proteins and cellular pathways of MDSC induced in less inflammatory conditions (conventional MDSC) and in highly inflammatory conditions (inflammatory MDSC) were compared using mass spectrometry. Pathway analysis and biological experiments revealed that inflammation enhanced MDSC accumulation by making MDSC less susceptible to apoptosis.  Collectively, these studies indicate that immunization with the immunogenic MHC II-restricted peptides while targeting inflammatory pathways that cause MDSC resistance to apoptosis may be a promising approach for breast cancer immunotherapy.

description: We study how the charge neutrality affects the phase structure of three-flavor PNJL model. We point out that, within the conventional PNJL model at finite density the color neutrality is missing because the Wilson line serves as an external ``colored'' field coupled to dynamical quarks. In this paper we heuristically assume that the model may still be applicable. To get color neutrality one has then to allow non vanishing color chemical potentials. We study how the quark matter phase diagram in $(T,m_s^2/μ)$-plane is affected by imposing neutrality and by including the Polyakov loop dynamics. Although these two effects are correlated in a nonlinear way, the impact of the Polyakov loop turns out to be significant in the $T$ direction, while imposing neutrality brings a remarkable effect in the $m_s^2/μ$ direction. In particular, we find a novel unlocking transition, when the temperature is increased, even in the chiral SU(3) limit. We clarify how and why this is possible once the dynamics of the colored Polyakov loop is taken into account. Also we succeed in giving an analytic expression for $T_c$ for the transition from two-flavor pairing (2SC) to unpaired quark matter in the presence of the Polyakov loop.

description: We compute the Bayesian evidences for one- and two-parameter models of evolving dark energy, and compare them to the evidence for a cosmological constant, using current data from Type Ia supernova, baryon acoustic oscillations, and the cosmic microwave background. We use only distance information, ignoring dark energy perturbations. We find that, under various priors on the dark energy parameters, LambdaCDM is currently favoured as compared to the dark energy models. We consider the parameter constraints that arise under Bayesian model averaging, and discuss the implication of our results for future dark energy projects seeking to detect dark energy evolution. The model selection approach complements and extends the figure-of-merit approach of the Dark Energy Task Force in assessing future experiments, and suggests a significantly-modified interpretation of that statistic.

Der Beginn des Projekts lag im Jahr 2020, das schon heute als Startpunkt in ein ,KI-Jahrzehnt‘ gelten kann. KI:edu.nrw war zum Beginn der Projektförderung das umfangreichste landesgeförderte KI-Vorhaben in Deutschland, das praxisorientiert auf die Verbesserung von Studium und Lehre zielte. Grundidee war es, die Einführung von Learning Analytics und Künstlicher Intelligenz in Studium und Lehre als gesamtorganisationale Gemeinschaftsaufgabe zu verstehen und zu betreiben. Entsprechend sondierten und erprobten den Einsatz der neuen Technologie in diesem Projekt sowohl alle lehrbezogenen Zentralbereiche (u. a. Didaktik, IT, Datenschutz, Studienberatung, Qualitätsmanagement) als auch Pilotvorhaben in unterschiedlichsten Fächergruppen (Erziehungswissenschaften, Maschinenbau, Mathematik, Medizin, Neuroinformatik, Sportwissenschaft). Flankierend fand ein umfangreicher Dialog- und Vernetzungsprozess statt, um sowohl innerhalb der als Pilothochschule geförderten Ruhr-Universität Bochum (RUB) und an der partnerschaftlich verbundenen RWTH Aachen als auch hochschulübergreifend in den unterschiedlichen Fächern und Sachgebieten Learning Analytics und KI zu diskutieren. Die Projektergebnisse können Hochschulen deutschlandweit (und darüber hinaus) leiten, wenn sie sich auf die neuen technischen Möglichkeiten einstellen wollen.

description: We analyze a superconductor-ferromagnet (S/F) system with a spiral magnetic structure in the ferromagnet F for a weak and strong exchange field. The long-range triplet component (LRTC) penetrating into the ferromagnet over a long distance is calculated for both cases. In the dirty limit (or weak ferromagnetism) we study the LRTC for conical ferromagnets. Its spatial dependence undergoes a qualitative change as a function of the cone angle θ. At small angles the LRTC decays in the ferromagnet exponentially in a monotonic way. If the angle θexceeds a certain value, the exponential decay of the LRTC is accompanied by oscillations with a period that depends on θ. This oscillatory behaviour leads to a similar dependence of the Josephson critical current in SFS junctions on the thickness of the F layer. In the case of a strong ferromagnet the LRTC decays over the length which is determined by the wave vector of the magnetic spiral and by the exchange field.

description: We study the neutrino pairs annihilation into electron-positron pairs ($ν+{\bar ν}\to e^- + e^+$) near the surface of a neutron star. The analysis is performed in the framework of extended theories of gravity. The latter induce a modification of the minimum photon-sphere radius ($R_{ph}$) and the maximum energy deposition rate near to $R_{ph}$, as compared to ones of General Relativity. These results might lead to an efficient mechanism for generating GRBs.

description: We propose a scheme of spin transistor using a $T$-shaped structure with local Rashba interaction. A wide antiresonance energy gap appears due to the interplay of two types of interference, the Fano-Rashba interference and the structure interference. A large current from the gap area can be obtained via changing the Rashba strength and/or the length of the sidearm by using gate voltage. The robustness of the antiresonance gap against strong disorder is demonstrated and shows the feasibility of this structure for the real application.

description: Weak lensing surveys provide a powerful probe of dark energy through the measurement of the mass distribution of the local Universe. A number of ground-based and space-based surveys are being planned for this purpose. Here, we study the optimal strategy for these future surveys using the joint constraints on the equation of state parameter wn and its evolution wa as a figure of merit by considering power spectrum tomography. For this purpose, we first consider an `ideal' survey which is both wide and deep and exempt from systematics. We find that such a survey has great potential for dark energy studies, reaching one sigma precisions of 1% and 10% on the two parameters respectively. We then study the relative impact of various limitations by degrading this ideal survey. In particular, we consider the effect of sky coverage, survey depth, shape measurements systematics, photometric redshifts systematics and uncertainties in the non-linear power spectrum predictions. We find that, for a given observing time, it is always advantageous to choose a wide rather than a deep survey geometry. We also find that the dark energy constraints from power spectrum tomography are robust to photometric redshift errors and catastrophic failures, if a spectroscopic calibration sample of 10^4-10^5 galaxies is available. The impact of these systematics is small compared to the limitations that come from potential uncertainties in the power spectrum, due to shear measurement and theoretical errors. To help the planning of future surveys, we summarize our results with comprehensive scaling relations which avoid the need for full Fisher matrix calculations.

description: We consider a spatially flat Friedmann--Lema\^ıtre--Robertson--Walker background space with an ideal gas and a multifield Lagrangian consisting of two minimally coupled scalar fields which evolve in a field space of constant curvature. For this cosmological model we classify the potential function for the scalar fields such that variational point symmetries exist. The corresponding conservation laws are calculated. Finally, analytic solutions are presented for specific functional forms of the scalar field potential in which the cosmological field equations are characterized as a Liouville integrable system by point symmetries. The free parameters of the cosmological model are constrained in order to describe analytic solutions for an inflationary epoch. Finally, stability properties of exact closed-form solutions are investigated. These solutions are scaling solutions with important physical properties for the cosmological model.

description: Climate change is a far-reaching, global phenomenon that will impact many aspects of our society, including the global stock market \cite{dietz2016climate}. In recent years, companies have increasingly been aiming to both mitigate their environmental impact and adapt to the changing climate context. This is reported via increasingly exhaustive reports, which cover many types of climate risks and exposures under the umbrella of Environmental, Social, and Governance (ESG). However, given this abundance of data, sustainability analysts are obliged to comb through hundreds of pages of reports in order to find relevant information. We leveraged recent progress in Natural Language Processing (NLP) to create a custom model, ClimateQA, which allows the analysis of financial reports in order to identify climate-relevant sections based on a question answering approach. We present this tool and the methodology that we used to develop it in the present article.

The 5-electron system is studied with exact diagonalization and group theory. The results indicate that the intermediate spin states are mixed symmetry states with a superposition of 5- and 4-fold electron-molecule configurations. A superposition of 5- and 4-fold correlation functions is found to reproduce the exact mixed symmetry pair correlation function to around 2%.

description: We investigate the evolution of an electron undergoing coherent tunneling via adiabatic passage (CTAP) using the solution of the one-dimensional Schroedinger equation in both space and time for a triple well potential. We find the eigenspectrum and complete time evolution for a range of different pulsing schemes. This also provides an example of a system that can be described with the tools from both quantum optics and condensed matter. We find that while the quantum optics description of the process captures most of the key physics, there are important effects that can only be correctly described by a more complete representation. This is an important point for applications such as quantum information processing or quantum control where it is common practice to use a reduced state space formulation of the quantum system in question.

The effect of active recovery on the post-exercise diffusion capacity

description: The purpose of this study was to investigate the effect of active recovery on the post-exercise pulmonary diffusion capacity (DL) and its two components, alveolar-capillary membrane diffusion capacity (DM) and pulmonary capillary blood volume (Vc). Ten trained non-smoking male cyclists ( age= 22 ± 2 yrs; ht = 177.4 ±7.1 cm; mass = 70.3 ± 9.1 kg; V0₂max = 61.0 ± 4.4 ml/kg/min) were recruited for this study. All subjects demonstrated normal pulmonary function with no history of respiratory disease. All spirometry and diffusion measurements were administered using the Collins PLUS DS II pulmonary function testing unit. Subjects cycled to exhaustion to determine maximal oxygen consumption (V0₂max) and ventilatory threshold (VT) on an electronically-braked cycle ergometerin their first visit. In the following two experimental trials labeled active recovery (AR) and inactive recovery (IR), all pulmonary diffusion measurements were performed. In both sessions, pre-exercise baseline values for DLco, DM and Vc were first obtained. Subjects then performed 45 minutes of cycling exercise at the individual's VT with maximal effort near the end. In only the AR trial, subjects performed an additional 30 minutes of cycling at 10% of individual's maximal power output immediately following the 45-minute exercise bout. Two additional pulmonary diffusion capacity measurements were made at 1 and 2 hours following the 45-minute submaximal exercise test. DM and Vc were calculated by measuring DLco at two inspired 0₂ concentrations using the technique of Roughton and Forster (1957). DLco was significantly reduced 1 hour post-exercise (p<0.05) and further reduced during the second hour of seated recovery in both AR and IR conditions (p<0.01). A significant reduction in DM following exercise was only observed in IR condition (p<0.05), while post-exercise DM remained at pre-exercise baseline level in AR condition. Vc was significantly decreased at 1 and 2 hours post-exercise in both conditions (p<0.05 and 0.01, respectively). Mean heart rate at 1 hour post-exercise was found to be higher than resting baseline (p<0.05), indicating that some of the decrease in DL, DM and Vc might have been masked by the elevated cardiac output. The most significant finding was that the depressed post-exercise DM was recovered by an active recovery, giving stronger support for the presence of pulmonary edema during and after the sustained effort which was partially responsible for the reduction in DM following exercise. Changes of Vc were in identical pattern and similar magnitude in both AR and IR conditions, suggesting that the distribution of central blood volume due to gravity might have greater effect on post-exercise Vc than the shunting mechanism. This study represents the first attempt to examine the effect of active recovery on the post-exercise pulmonary diffusion capacity.

description: In this proceeding, the phenomenology of Universal Extra Dimensions (UED), in which all the Standard Model fields propagate, is explored. We focus on models with one universal extra dimension, compactified on an $S_1/Z_2$ orbifold. We revisit calculations of Kaluza-Klein (KK) dark matter without an assumption of the KK mass degeneracy including all possible coannihilations. We then contrast the experimental signatures of low energy supersymmetry and UED.

description: We proposed a simple and efficient modular single-source surface integral equation (SS-SIE) formulation for electromagnetic analysis of arbitrarily connected penetrable and perfectly electrical conductor (PEC) objects in two-dimensional space. In this formulation, a modular equivalent model for each penetrable object consisting of the composite structure is first independently constructed through replacing it by the background medium, no matter whether it is surrounded by the background medium, other media, or partially connected objects, and enforcing an equivalent electric current density on the boundary to remain fields in the exterior region unchanged. Then, by combining all the modular models and any possible PEC objects together, an equivalent model for the composite structure can be derived. The troublesome junction handling techniques are not needed and non-conformal meshes are intrinsically supported. The proposed SS-SIE formulation is simple to implement, efficient, and flexible, which shows significant performance improvement in terms of CPU time compared with the original SS-SIE formulation and the Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT) formulation. Several numerical examples including the coated dielectric cuboid, the large lossy objects, the planar layered dielectric structure, and the partially connected dielectric and PEC structure are carried out to validate its accuracy, efficiency and robustness.

The role of the circadian clock gene LUX ARRHYTHMO in regulating innate immunity in Arabidopsis

description: Each year pathogen-caused plant diseases are responsible for massive losses in crop yields and have tremendously impacted global economy. To more effectively fight off these diseases it is imperative to better understand how plants activate their immune responses. The circadian clock is the internal time measuring machinery that regulates many physiological processes of organisms. Recent studies from our and several other groups have demonstrated the roles of day-time components of the central oscillator of Arabidopsis biological clock, CIRCADIAN CLOCK ASSOCIATED 1 (CCA1)  and LATE ELONGATED HYPOCOTYL (LHY),, in regulating defense responses.  In this study I investigate the role of the night-time circadian clock component, LUX ARRHYTHMO (LUX), in defense control. Results from my experiments suggest that LUX plays a critical role in resistance to a virulent P. syringae strain but not two isogenic avirulent strains, suggesting a contribution of LUX in basal defense. Genetic analysis with a defense-sensitized acd6-1 mutant further revealed that LUX acts through salicylic acid-mediated defense pathway.  This study demonstrates a role of an additional key component of the circadian clock in defense control, highlighting the importance of the circadian clock in regulating plant innate immunity.
Logarithmic correction to black hole entropy from the nonlocality of quantum gravity

description: It has been known for many years that the leading correction to the black hole entropy is a logarithmic term, which is universal and closely related to conformal anomaly. A fully consistent analysis of this issue has to take quantum backreactions to the black hole geometry into account. However, it was always unclear how to naturally derive the modified black hole metric especially from an effective action, because the problem refers to the elusive non-locality of quantum gravity. In this paper, we show that this problem can be resolved within an effective field theory (EFT) framework of quantum gravity. Our work suggests that the EFT approach provides a powerful and self-consistent tool for studying the quantum gravitational corrections to black hole geometries and thermodynamics.

Constraints for the existence of flat and stable non-supersymmetric vacua in supergravity

description: We further develop on the study of the conditions for the existence of locally stable non-supersymmetric vacua with vanishing cosmological constant in supergravity models involving only chiral superfields. Starting from the two necessary conditions for flatness and stability derived in a previous paper (which involve the Kahler metric and its Riemann tensor contracted with the supersymmetry breaking auxiliary fields) we show that the implications of these constraints can be worked out exactly not only for factorizable scalar manifolds, but also for symmetric coset manifolds. In both cases, the conditions imply a strong restriction on the Kahler geometry and constrain the vector of auxiliary fields defining the Goldstino direction to lie in a certain cone. We then apply these results to the various homogeneous coset manifolds spanned by the moduli and untwisted matter fields arising in string compactifications, and discuss their implications. Finally, we also discuss what can be said for completely arbitrary scalar manifolds, and derive in this more general case some explicit but weaker restrictions on the Kahler geometry.

description: Sexual selection results from the competition over mating opportunities in natural populations. Just as natural selection favors traits that increase survival and fecundity, sexual selection favors traits that increase mating opportunities and fertilization success. These two processes cause changes within populations but are also important in driving divergence between populations. Speciation by divergent natural selection, also called ecological speciation, is now a widely accepted driver of diversity; however the role of sexual selection is less concrete. Speciation by sexual selection is thought to occur via divergence in female mating preferences between populations followed by coevolution of male mating traits. These differences eventually lead to behavioral reproductive isolation as female preferences in one population no longer correspond to male traits in another. Although verbal and quantitative models demonstrate the plausibility of speciation by sexual selection, empirical examples are relatively few and evidence often comes from comparative datasets that rely on proxy measures of divergent sexual selection. Additionally, natural and sexual selection often interact making it difficult to distinguish speciation by sexual selection alone. Here, I address the potential for speciation by natural selection, by sexual selection, or by a combination of the two in a group of freshwater fishes commonly called darters (Etheostoma). My results suggest a primary role for sexual selection in early darter divergence. Interestingly, however, trait divergence and the evolution of behavioral isolation in darters appear to involve divergence in male aggressive responses and male mate preferences, respectively. Further, differences in the sexual environment predict total reproductive isolation between species while differences in the ecological environment do not. The influence of male behavior was unexpected given the overwhelming focus on divergence in female mate preferences in speciation by sexual selection models. Additionally, the potential for divergence in sexual selection to promote reproductive barriers outside behavioral isolation is surprising. Taken together, my results suggest that early darter divergence is driven by sexual selection and imply that the definition of speciation by sexual selection should be expanded to encompass the multiple mechanisms of sexual selection and how they might contribute to all reproductive barriers.

description: We propose a model for early universe cosmology without the need for fundamental scalar fields. Cosmic acceleration and phenomenologically viable reheating of the universe results from a series of energy transitions, where during each transition vacuum energy is converted to thermal radiation. We show that this `cascading universe' can lead to successful generation of adiabatic density fluctuations and an observable gravity wave spectrum in some cases, where in the simplest case it reproduces a spectrum similar to slow-roll models of inflation. We also find the model provides a reasonable reheating temperature after inflation ends. This type of model may also be relevant for addressing the smallness of the vacuum energy today.

description: We report on a measurement of the inclusive jet cross section in $p \bar{p}$ collisions at a center-of-mass energy $\sqrt s=$1.96 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider corresponding to an integrated luminosity of 0.70 fb$^{-1}$. The data cover jet transverse momenta from 50 GeV to 600 GeV and jet rapidities in the range -2.4 to 2.4. Detailed studies of correlations between systematic uncertainties in transverse momentum and rapidity are presented, and the cross section measurements are found to be in good agreement with next-to-leading order QCD calculations.

description: We analyze the nMSSM with CP violation in the singlet sector. We study the static and dynamical properties of the electroweak phase transition. We conclude that electroweak baryogenesis in this model is generic in the sense that if the present limits on the mass spectrum are applied, no severe additional tuning is required to obtain a strong first-order phase transition and to generate a sufficient baryon asymmetry. For this we determine the shape of the nucleating bubbles, including the profiles of CP-violating phases. The baryon asymmetry is calculated using the advanced transport theory to first and second order in gradient expansion presented recently. Still, first and second generation sfermions must be heavy to avoid large electric dipole moments.
