description: Large scale, homogeneous quasi-free standing monolayer graphene is obtained on cubic silicon carbide, i.e. the 3C-SiC(111) surface, which represents an appealing and cost effective platform for graphene growth. The quasi-free monolayer is produced by intercalation of hydrogen under the interfacial, (6root3x6root3)R30-reconstructed carbon layer. After intercalation, angle resolved photoemission spectroscopy (ARPES) reveals sharp linear pi-bands. The decoupling of graphene from the substrate is identified by X-ray photoemission spectroscopy (XPS) and low energy electron diffraction (LEED). Atomic force microscopy (AFM) and low energy electron microscopy (LEEM) demonstrate that homogeneous monolayer domains extend over areas of hundreds of square-micrometers.

High task demand in dual-target paradigm redirects experimentally increased anxiety to uphold goal-directed attention

Subjects: subject: anxiety, attentional control, goal-directed attention, distractor, visual search
subject: 610 Medizin

description: Previous research has shown that state anxiety facilitates stimulus-driven attentional capture and impairs goal-directed attentional control by increasing sensitivity to salient distractors or threat cues or narrowing spatial attention. However, recent findings in this area have been mixed, and less is known about how state-dependent anxiety may affect attentional performance. Here, we employed a novel dual-target search paradigm to investigate this relationship. This paradigm allowed us to investigate attentional control and how focus narrows under different anxiety states. Participants watched a short movie—either anxiety-inducing or neutral—before engaging in the dual-target visual search task. We found that they performed faster and more accurately in trials without the salient distractor compared to those with distractors, and they performed better in tasks presented on the center than the periphery. However, despite a significant increase in self-reported anxiety in the anxiety-inducing session, participants’ performance in terms of speed and accuracy remain comparable across both anxious and neutral sessions. This resilience is likely due to compensatory mechanisms that offset anxiety, a result of the high demands and working memory load inherent in the dual-target task.

description: We reexamine the topological and nonlocal natures of the Aharonov-Casher and scalar Aharonov-Bohm phase effects. The underlying U(1) gauge structure is exhibited explicitly. And the conditions for developing topological Aharonov-Casher and scalar Aharonov-Bohm phases are clarified. We analyse the arguments of M. Peshkin and H. J. Lipkin (Phys. Rev. Lett. 74, 2847(1995)) in detail and show that they are based on the wrong Hamiltonian which yields their conclusion incorrect.

description: The present assessment of Rotifera biodiversity of the eastern Himalayas reveals a total of 172 species belonging to 39 genera and 19 families from Arunachal Pradesh, the northeastern-most state of India. The richness forms ~59% and ~40% of the rotifer species known till date from northeast India (NEI) and India, respectively. Three species are new to the Indian sub-region, four species are new to NEI and 89 species are new to Arunachal Pradesh; 27 species indicate global distribution importance and 25 species reported exclusively from NEI merit regional interest. The rich and diverse alpha di- versity and biogeographic interest of Rotifera of this Himalayan biodiversity hot-spot is noteworthy in light of predominance of the small lentic ecosystems. Lecanidae > Brachionidae > Lepadellidae > Trichocercidae collectively comprise ~71% of total rotifer species. Brachionidae records the highest richness known from any state of India. This study indicates the role of thermophiles with overall importance of ‘tropic-centered’ genera Lecane and Brachionus, and particularly at lower altitudes; species of ‘temperate-centered’ genera Keratella, Notholca and Synchaeta are notable in our collections at middle and higher altitudes, while Trichocerca and Lepadella are other species-rich genera. The rotifer fauna shows a mixture of ‘tropical’ and ‘cold-water’ elements, depicts the littoral-periphytonic character, and records a large component of cosmopolitan species. The study of more collections from middle and higher altitudes of Arunachal Pradesh are desired for an update on Rotifera from the eastern Himalayas.

description: The purpose of this study was to examine personality traits associated with disordered eating, problem gambling, and comorbid eating and gambling problems to determine whether they shared similar underlying mechanisms. Participants were 1002 adult men and women from four age cohorts recruited through random digit dialing. Participants completed self-report measures of negative affectivity, the tendency to give into strong urges, the desire for excitement, difficulty persisting on tasks, disordered eating, and gambling. Negative affectivity and tendency to give into strong urges were associated with disordered eating and gambling severity, whereas desire for excitement was only associated with gambling. Individuals with comorbid eating and gambling problems had more extreme scores on some personality traits relative to non-disordered individuals but they did not differ from those with disordered eating or problem gambling. Negative affectivity and tendency to give into strong urges may represent shared mechanisms associated with disordered eating and problem gambling.
A Modeling Framework to Investigate the Impact of Climate and Land-Use/Cover Change on Hydrological Processes in the Elbow River Watershed in Southern Alberta

subject: climate change
subject: MIKE SHE/MIKE 11
subject: Cellular Automata

description: Complex dynamical and physical interactions exist between climate, land use/cover (LULC), and hydrology. In fact, each of these systems is considered complex because they possess the following characteristics. They consist of a large number of components that interact in a non-linear way. They interchange information with their surroundings and constantly modify their self-organized structure. They are far-from-equilibrium and display instability, sensitivity to initial conditions, sudden changes, and a behavior that cannot be captured by simple models. Understanding how hydrological processes respond to climate and LULC change requires knowledge about how these complex systems interact in the present and how they might in the future. The objective of this research is to understand the responses of hydrological processes to climate and LULC change in the Elbow River watershed using an integrated modeling framework that can address the complexity of these interrelated systems. To achieve this goal, the physically-based, distributed MIKE SHE/MIKE 11 model was coupled with a LULC cellular automata to simulate hydrological processes up to the year 2070 under five GCM-scenarios (NCARPCM-A1B, CGCM2-B2(3), HadCM3-A2(a), CCSRNIES-A1FI, and HadCM3-B2(b)). Results reveal that most scenarios generate an increase in overland flow, baseflow, and evapotranspiration in the winter/spring, and a decrease in the summer/fall. The highest increase in streamflow occurs in mid-late spring due to an increase in snowmelt and rain-on-snow events that may enhance the risk of flooding. In addition, LULC change substantially modifies the river regime in the east sub-catchment, where urbanization occurs. The separated impacts of climate and LULC change on streamflow are positively correlated in winter and spring, which intensifies their influence and leads to a rise in streamflow, which in turn increases the vulnerability of the watershed to floods, particularly in spring. Flow duration curves indicate that LULC change has a greater contribution to peak flows than climate change in both the 2020s and 2050s. The integrated modeling framework used in this research is a powerful analytical tool that can help scientists and decision makers for the planning of sustainable water resources and infrastructure management.

description: By spatially mapping the Doppler effect of an in-plane magnetic field on the quasiparticle tunneling spectrum, we have laterally imaged the vortex lattice in superconducting 2H-NbSe2. Cryomagnetic scanning tunneling spectroscopy was performed at 300 mK on the ab-surface oriented parallel to the field H. Conductance images at zero bias show stripe patterns running along H, with the stripe separation varying as H^-0.5. Regions of higher zero-bias conductance show lower gap-edge conductance, consistent with spectral redistribution by spatially-modulated superfluid momentum. Our results are interpreted in terms of the interaction between vortical and screening currents, and demonstrate a general method for probing subsurface vortices.

description: The geomechanical responses of a coal seam and its surrounding strata in underground coal gasification (UCG) are significant owing to the high temperature nature of the UCG process and the cavity evolution. In this thesis, the results from a reservoir simulator are coupled with a geomechanical module to solve for the displacement and stress variations. A controlled retracting injection point (CRIP) method is applied in the reservoir simulator to model reactions and geochemistry. The stress solution results of some UCG example problems are discussed by applying three constitutive models of linear elastic, hyperbolic, and elasto-plastic. In a simpler method, shear softening and post-failure behavior of the coal is captured by imposing the stress rebalancing on the linear elastic model to mimic the elasto-plastic solution. Finally, the two compelling factors of high temperature and cavity evolution, which have the highest contributions to the geomechanical responses, are comprehensively investigated in different sensitivity analyses.

description: The use of herbomineral formulation in the healthcare sector for different chronic diseases is gaining popularity due to its fewer side effects, high safety profile, and cost effectiveness. A new proprietary herbomineral formulation was formulated, consisting of four essential ingredients viz. herbal root extract (ashwagandha), and minerals (zinc, magnesium, and selenium). The study aims to evaluate the in vitro effect of Biofield Energy Healing (The Trivedi Effect®) on the test formulation using murine dendritic (DCs) and splenocyte cells. The herbomineral formulation was divided into two parts; one was represented as control, while the other part was treated with the Biofield Energy Healing Treatment remotely by eighteen renowned Biofield Energy Healers (The Trivedi Effect®) and defined as the Biofield Treated formulation. The effect of the test formulation on these cells were monitored by an estimation of pro-inflammatory cytokines level such as tumor necrosis factor (TNF-α), macrophage inflammatory protein (MIP-1α), and interleukin (IL-1β) in cell culture supernatants at the non-cytotoxic concentrations of the test formulation using MTT assay. The DCs were treated with the Biofield Energy Treated test formulation at different concentrations (i.e. 1.05 to 1052.5 µg/mL) for 24 hours, and the results showed significant (p≤0.001) suppression of TNF-α levels at all the tested concentrations with a maximum percentage decrease by 43.64% at 5.2 µg/mL concentration in the Biofield Treated formulation as compared with the untreated test formulation. Further, the Biofield Treated formulation also demonstrated inhibition of MIP-1α and IL-1β at a concentration range of 0.0000105 to 10.5 µg/mL in LPS stimulated splenocyte cells. There was a significant (p≤0.001) inhibition of MIP-1α (26.52%) and IL-1β (35.28%) in the Biofield Treated test formulation at concentration 0.000105 µg/mL and 0.0000105 µg/mL, respectively in comparison to the untreated test formulation. Overall, these results suggest that the Biofield Energy Healing based herbomineral formulation (The Trivedi Effect®) significantly down-regulated the tested cytokines expression in DCs and splenocyte cells as compared to the untreated formulation. Therefore, the Biofield Healing based formulation might be useful as a better anti-inflammatory product for many chronic and acute inflammatory disease conditions and autoimmune disorders. The Biofield Energy Treatment based formulation can also be effectively applied in cases of organ transplants, stress management and anti-aging by improving overall health.

description: Phonon dispersions of one typical three-dimensional topological insulator Bi$_{2}$Se$_{3}$ have been studied within density functional theory. The soft modes of two acoustic branches along the $Z$$-$$F$ and $Γ$$-$$F$ directions within the pure local density approximation will transit to show imaginary frequency oscillating after including the spin-orbit interaction (SOI). Similar phenomenon has also been observed for Bi$_{2}$Te$_{3}$. Besides, we have found that the weak van der Waals forces between two Se1 layers in Bi$_{2}$Se$_{3}$ are strengthened by turning on the SOI.

Design and biomechanical evaluation of a rodent spinal fixation device
Creators: name: Shahrokni, Maryam
Publisher: name: University of British Columbia
Year: 2010

description: Previous experimental studies of spinal cord injury (SCI) in rodents established the importance of fixation of the spine in survival models following a mechanical injury. However, no fixation device has been designed to provide spinal stabilization, prevent additional damage to the cord, and promote fusion at the site of injury. The present study aims to design a novel rat spinal fixation device, which will be used in future survival studies and investigates its biomechanical effectiveness in stabilizing the spine up to eight weeks post injury. A custom-made magnetic resonance imaging (MRI) compatible fixation device was designed to stabilize the C5/C6 joint. This was achieved in an animal model by creating a 1.5 mm fracture-dislocation injury between C5 and C6 spinal segments of Sprague-Dawley rats using a multimechanism SCI test system. A biomechanical evaluation of the device-spine system was conducted at these segments. Cycles of stepwise directed shear forces with a maximum of 0.98 N were applied at a known distance from the injured site producing flexion and extension bending moments, while the resulting two-dimensional motions between C5 and C6 were measured and presented in the form of load-displacement curves. This was implemented at two time points: immediately (n = 6), and eight weeks post-injury (n = 9) and the results were compared to an intact group (n = 6). Average ± S.D. flexion/extension ranges of motion (ROM) were 18.1 ± 3.3º, 19.9 ± 7.5º, and 1.5 ± 0.7º, and neutral zones (NZ) were 3.4 ± 2.8º, 5.0 ± 2.4º, and 0.7 ± 0.5º, respectively for the intact, injured/fixed, and injured/8-week groups. The results show that there is a significant difference in ROM and NZ between the injured/fixed and injured/8-week groups (p-values = 0.0002, and 0.006, respectively). The device acutely stabilizes the spine by restoring its stiffness to the initial stiffness of the intact specimen. It also proves that along with the biological factors over time, fusion is promoted at the site of injury. This study presents the design and evaluation of a novel well-characterized spinal fixation device for rats, which will be used in future experimental SCI survival models.

description: Massive data sets have been accumulated in the oil and gas industry. As strategic assets, voluminous data of different data types should be leveraged and turned into information for agile and accurate decision-making. Three oil and gas data-related studies are covered in this thesis. Firstly, a data-driven model is proposed for predicting well production using time-series production data from analogous and adjacent wells. Secondly, interactive visualization tools are designed and implemented for oil and gas spatial and temporal datasets, following an “Overview first, zoom and filter, then details-on-demand” guideline (Shneiderman, 1996) in order to maximize information delivery in single displays. Thirdly, a web-based Geographic Information System (GIS) application is designed and implemented for a Steam Assisted Gravity Drainage (SAGD) dataset to provide users convenient access to public and proprietary SAGD data, as well as some data analysis and visualization functions.

description: In this paper we consider the conditions on quasi-thermal-incompressible so that they satisfy all the principles of thermodynamics, including the stability condition associated with the concavity of the chemical potential. We analyze the approximations under which a quasi-thermal-incompressible medium can be considered as incompressible. We find that the pressure cannot exceed a very large critical value and that the compressibility factor must be greater than a lower limit that is very small. The analysis is first done for the case of fluids and then extended to the case of thermoelastic solids.

Subjects: subject: Educational Psychology

description: Research in the area of piercings and tattoos has indicated the existence of commonly held stereotypes and assumptions (stigmas) concerning these body practices. These stigmas have been shown to impact the hireability of those with body modifications; women more so than men. In order to better understand the experiences of women with piercings and tattoos who are going into the professional workforce I interviewed 8 post-secondary women. A hermeneutic phenomenological approach was used utilizing van Manen’s 6 activities for inquiry. Supplementary research using the Inventory of Parent and Peer Attachment Revised scale was conducted to see how relationships with family and friends influence or result in stigma experiences. Eight main themes were created through interpretation of the findings. It was discovered that, despite the mainstream obtainment of body modification (BoM), post-secondary women are still experiencing and/or anticipating workplace stigma. Implications of these findings for career counselling are discussed.

This quasar was initially detected as an i dropoutout in PS1, confirmed photometrically with the SAO Widefield InfraRed Camera (SWIRC) at Arizona's Multiple Mirror Telescope (MMT) and the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) at the MPG 2.2 m telescope in La Silla. The quasar was verified spectroscopically with the the MMT Spectrograph, Red Channel and the Cassegrain Twin Spectrograph (TWIN) at the Calar Alto 3.5 m telescope. It has a redshift of 5.73, an AB z magnitude of 19.4, a luminosity of 3.8 x 10^47 erg/s and a black hole mass of 6.9 x 10^9 solar masses. It is a Broad Absorption Line quasar with a prominent Ly-beta peak and a very blue continuum spectrum. This quasar is the first result from the PS1 high redshift quasar search that is projected to discover more than a hundred i dropout quasars, and could potentially find more than 10 z dropout (z > 6.8) quasars.

description: Ground-based observation of Interplanetary Scintillation(IPS) is an important approach of monitoring solar wind. A ground-based IPS observation system is newly implemented on 50m radio telescope, Miyun station, National Astronomical Observatories, Chinese Academy of Sciences(NAOC). This observation system is constructed for purpose of observing the solar wind speed and scintillation index by using the normalized cross-spectrum of simultaneous dual-frequency IPS measurement. The system consists of a universal dual-frequency front-end and a dual-channel multi-function back-end specially designed for IPS. After careful calibration and testing, IPS observations on source 3C273B and 3C279 are successfully carried out. The preliminary observation results show that this newly developed observation system is capable of doing IPS observation.The system sensitivity for IPS observation can reach over 0.3Jy in terms of IPS polarization correlator with 4MHz bandwidth and 2s integration time.

description: A goal-driven mobile robot navigation system is proposed for unknown indoor environments. The proposed system can be subdivided into four main modules, namely, localization, mapping, motion control, and goal detection. In the proposed system, a mobile robot uses an odometry system and a Kinect sensor as its input devices. An optimal particle filter models the posterior over the robot trajectory while minimizing the variance of the importance weights of the particles. Occupancy grid maps are employed to represent the environment as they do not make any assumptions on distinguishable landmarks. A nearness-diagram reactive navigation technique generates motion commands based on the robot position and navigation goal location. A trajectory parameter space is used as an abstraction layer of the robot shape and kinematic constraints for the nearness-diagram method. A goal-driven situation assessment framework based on fuzzy cognitive maps is developed to verify navigation goals using sensory information and expert knowledge.

The subject of this portrait has traditionally been identified as Cardinal Andrea of Austria, most likely due to his family’s connections with the Spanish monarchy. However, careful examination of both prelates’ likenesses and an investigation into their artistic interests has resulted in a reassessment. The identification of the sitter establishes this as the first-known preserved Italian artwork relating to Cardinal Quiroga, and thereby opens up new lines of enquiry for research into his profile as an art patron and collector.

description: We investigate the thermal conductivity of four types of deformed carbon nanotubes by using the nonequilibrium molecular dynamics method. It is reported that various deformations have different influence on the thermal properties of carbon nanotubes. For the bending carbon nanotubes, the thermal conductivity is independent on the bending angle. However, the thermal conductivity increases lightly with XY-distortion and decreases rapidly with Z-distortion. The thermal conductivity does not change with the screw ratio before the breaking of carbon nanotubes but decreases sharply after the critical screw ratio.

description: Malaysia’s plantation industry and economy, as a whole, has benefitted from foreign labor and remains crucially dependent upon it. Yet, this dependence can prevent optimum productivity by disincentivizing mechanization and innovation. Furthermore, foreign workers have historically filled gaps left by Malaysians seeking higher education and higher-income jobs, but evolving policies and practices in Malaysia’s plantation sector, occurring alongside expansion of Indonesia’s plantation sector, are changing the nature of the mechanization-versus-cheap labor dichotomy that has long affected the industry. While there has been a fair amount of research dedicated to technical advancements in palm oil harvesting, as well as quantitative analyses of economic impacts of migrant labor across multiple industries, the current discourse lacks primary qualitative data on the impacts of recent migration trends on mechanization, productivity, safety, and worker turnover in plantations. This paper explores these questions through interviews conducted with key stakeholders from several levels of Malaysia’s palm oil industry, including individuals affiliated with plantation companies, government ministries, non-governmental organizations, and universities/research institutions. Results of this analysis suggest that foreign worker inflows are insufficient to satisfy labor requirements, even as technology and farming best practices are increasingly adopted. Increased focus on genetic innovation and diversification, as well as social and educational program improvement, are necessary to address labor and productivity challenges. Moreover, a focus on replacing foreign labor with local labor is not maximally effective and should instead be shifted to retaining foreign labor and, where relevant, training Malaysians for more technical and managerial positions in the industry.

description: Recent Monte Carlo simulations on the Kern and Frenkel model of a Janus fluid have revealed that in the vapour phase there is the formation of preferred clusters made up of a well-defined number of particles: the micelles and the vesicles. A cluster theory is developed to approximate the exact clustering properties stemming from the simulations. It is shown that the theory is able to reproduce the micellisation phenomenon.

description: The purpose of this dissertation is to explore the critical elements adopted by practicing Jordanian architects in incorporating local and global cultural themes in design thinking and architectural design. A key informant ethnographic approach was used in interviewing five Jordanian architects considered as ‘experts’ in integrating local and global influences in their buildings. The themes that emerged from these expert practitioner interviews include the critical elements of critical reflection and inquiry into the historical and contemporary local and global contexts and cultural influences. The changing role of the architect and the relationship between architecture and the real estate development industry also emerges as an important theme. There has been very little research into the process of professional architectural practice and the intention of this research is to illustrate the importance of understanding design thinking in design practice in order to better inform architectural education. Since the initial and traditional examination on Jordanian architecture prior to 1990 there has been a number of emerging Jordanian architects and changes in architectural practice and design thinking that have not been documented. The results of this research are intended to engage more architectural discussion and criticism about contemporary architecture and its influences and dynamic local and global contexts. Over the last two decades globalization has affected architectural design and architectural practice and contemporary cultural ‘visions’ of urban form. This flows of communication across geographic and cultural boundaries associated with globalization presents critical challenges in design to mediate between the local and the global. This requires much more than simply the replication of stylized ‘norms’ or imitation of past highly stereotyped imagery. As a profession that helps shape the built environment, it is important to understand how recognized architects engage in the process of mediating local and global influences in specific social, cultural, ecological and economic contexts. The results of this ethnographic approach to understanding successful architectural practice in Jordan suggest that the rediscovery of the uniqueness of cultural meaning in place is still a critical element in enabling contemporary architectural practice that is enabling Jordanian architecture to be sensitive to the flow and continuity of context in mediating global and local forces through design.

description: Global Navigation Satellite System (GNSS) technology has undergone enormous developments over the last three decades. The majority of PNT (Positioning, Navigation and Timing) applications are now based on GNSS. This increasing dependence on GNSS technology is acknowledged by several nations, some of which are even developing their own regional or global systems. Several techniques exist to increase accuracy, reliability and availability of GNSSs. Real-time PPP (Precise Point Positioning) is the preferred GNSS positioning technology for most offshore applications that require higher performance than standalone GNSS provides. PPP is possible in any location worldwide without the need of local infrastructure. This makes PPP very advantageous when at sea far away from land. PPP uses precise orbits and precise clocks and can be provided globally with a network of fewer reference stations than any other comparable GNSS augmentation technology. PPP has over the last few years become the industry standard for offshore vessels operating with Dynamic Positioning (DP) systems. Further improvements of PPP technology are still desirable with respect to availability, reliability, accuracy and convergence time even for offshore applications. The research presented herein addresses improvements in these areas from three different angles, namely integration of different GNSSs, multi-frequency observations and PPP-RTK methods. The first innovative part of this research is the interchangeable integration of GPS-Galileo and GPS-BeiDou in PPP. It improves availability and accuracy in situations when few satellites are in view. New ionosphere-free widelane combinations for Galileo, GPS, BeiDou and GLONASS have been developed. These can improve PPP initial position accuracy by a factor two or more, i.e. from the 1.6 m to 0.8 m level. An ionosphere estimation technique for UPDs (Uncalibrated Phase Delays) especially tailored for multi-frequency observations is developed with applications smoothing and merging. Findings show how multi-frequency observations can increase PPP-RTK performance in offshore environments. Furthermore, improved precise clocks using UPDs increase position accuracy of both float PPP and PPP-RTK. Finally ten recommendations are given. The combination of these, the completion of the new GNSSs Galileo and BeiDou and the scheduled improvements of the existing GPS and GLONASS are expected to make instant high-accuracy PPP-RTK possible.
Genome-wide analysis of chromatin modification patterns and their functional associations with major cellular processes in Saccharomyces cerevisiae

description: Chromatin is a nucleoprotein complex packaging DNA inside the cell nucleus and is of crucial relevance for genome regulation. Its structure is highly dynamic undergoing post-translational modifications, replacement by histone variants, and ATP-dependent remodelling. My dissertation aims to better understand the regulation of chromatin by studying the structure and function of a chromatin modifier, mapping chromatin modifications at a genome-wide scale, and linking modification patterns to cellular functions in the model organism Saccharomyces cerevisiae. Multiple chromatin modifying and transcription complexes contain a YEATS domain, and their misregulation has been implicated in the development of cancer. This study recognizes the evolutionary conservation of the YEATS domain from yeast to human, presents its structural composition as well as its function in depositing the histone variant H2A.Z. Besides histone variants, histone modifications determine chromatin structure and often co-occur in certain genomic regions. Histone H3 lysine 79 methylation is one such modification that adds an additional level of complexity being either mono-, di- or trimethylated (H3K79me1, me2, me3). In this work, I show that these methylation states are functionally not redundant as previously proposed, and that H3K79 di- and trimethylation are associated with different regions of the genome. In contrast to H3K79me3, H3K79me2 marks M/G1 cell cycle regulated genes and its levels change during the cell cycle. The trigger for trimethylation of H3K79, as well as for trimethylation of lysine 4 on histone H3 (H3K4me3), is monoubiquitination of histone H2B (H2BK123ub). The map of H2BK123ub that I present herein demonstrates its role as upstream regulator for H3K79me3 and H3K4me3 on a genome-wide scale. Removal of the transient H2BK123ub mark is facilitated by the deubiquitinases Ubp8 and Ubp10. I herein reveal that they mainly act at distinct genomic loci. While Ubp8 removes H2BK123ub at sites enriched for H3K4me3, Ubp10 functions at those marked by H3K79me3. Finally, my thesis describes chromatin signatures of multiple modifications, and finds the combination of H2BK123ub, H3K4me3, and H3K36me3 to be specific for highly transcribed genes, including those containing introns. In this context, I show evidence that link the histone H2B ubiquitin ligase Bre1 to mRNA splicing.
