title: Exploration of Metagenomic Racemases for Biosynthetic Cascades
Creators: name: Poschenrieder, Silvan Wolf
Publisher: name: UNSPECIFIED
Year: 2025

description: Biocatalysis becomes more and more appealing to industry due to its inherent ability to address contemporary demands for ecological, stereoselective synthesis from benign and biologically sourced materials, like amino acids. This creates an endless desire for new, diverse enzyme catalysts. One of the advantages of biocatalysis is to inherently provide catalysts for dynamic kinetic resolution like amino acid racemases, which is key to economic stereoselective synthesis. Drawback of most known amino acid racemases is their specificity for only few amino acids. Therefore, this work is dedicated to finding new and unusual amino acid racemases within a library that was created by our industry partner Prozomix Ltd. from their metagenomic database. Besides discovering enzymes with broader, or rare reactivities, the goal was also to demonstrate their synthetic potential in biocatalytic one-pot sequential cascade reactions.
First step was to adapt a spectrophotometric assay to enable efficient probing of the 56 library enzymes for activity on 16 canonical and 14 selected non-canonical amino acids. In addition, the enzymes’ melting points were measured with nanoDSF to assess their thermal stability. Subsequently, biocatalytic reaction cascades were implemented. For the production of the rare sugars 5-deoxy- and 1,5-dideoxyfructose, the detected racemase-hits were combined with D-amino acid oxidase and transketolase, and comparing this oxidase pathway with an alternative transaminase pathway. Valuable 2-keto acids, and D-2-hydroxy acids were produced, employing selected racemases together with oxidase and stereoselective dehydrogenase enzymes. Moreover, new techniques were developed to improve one of these cascades’ critical sub-process, the provision of oxygen to the oxidase at laboratory-scales. Required substrates for screening and sugar-producing cascades were synthesized, optimizing existing protocols and developing new, improved routes and methodologies.
Several racemases with remarkable substrate ranges were discovered, for example enzymes racemising tyrosine, or acting on the dipeptide β-aspartame. Some of the panel enzymes show both, broad substrate range and high thermostability of Tm > 69 °C. Their synthetic potential was successfully demonstrated by producing rare sugars and amino acid derivatives with productivities of up to 15.3 g D-phenyllactic acid per gram of cell-free racemase extract. Thus, the research goal to discover useful, innovative racemases, fit for synthetic application in dynamic kinetic resolutions was achieved and these novel enzymes may even serve as starting points for enzyme engineering.

description: Trans people in the US deal frequently with death, from being mourned while living, to the deaths of community members, to facing their own vulnerability in medical and end of life settings. This thesis focuses on how trans people, using the sites Reddit, Youtube, and Tumblr, take up death through online communities to establish community archives, maintain bodily autonomy, and imagine trans futures. Analyzing 7 months of ethnographic research on Tumblr, Reddit, and Youtube, I find that trans social media users in these spaces share resources (financial, medico-legal, and educational), publicly mourn, and express their autonomy in order to manage living in biopolitical and necroviolent systems. In many ways, these survival mechanisms constitute community care work, which expand upon the ways the concept of autonomy is constructed and how we perceive cyberspace as a structure for community connection.

description: Socioeconomic gaps in college enrollment and attainment have widened over time, despite increasing returns to postsecondary education and significant policy efforts to improve access. We describe the barriers that students face during the transition to college and review the evidence on potential policy solutions. We focus primarily on research that examines causal relationships using experimental or quasi-experimental methods, though we draw upon descriptive evidence to provide context. Our review is distinctive in three respects. First, in addition to the literature on financial aid, we examine the evidence on informational and behavioral interventions, academic programs, and affirmative action policies intended to improve college access. Second, we incorporate a wealth of recent research not included in prior reviews. Finally, we conceptualize college access broadly, as including not just whether but also where students attend and whether they have access to college-level courses. We conclude with a discussion of implications for policy and research.

Lie algebroids, non-associative structures and non-geometric fluxes

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In the first part of this article, the geometry of Lie algebroids as well as the Moyal-Weyl star product and some of its generalizations in open string theory are reviewed. A brief introduction to T-duality and non-geometric fluxes is given. Based on these foundations, more recent results are discussed in the second part of the article. On the world-sheet level, we will analyse closed string theory with flat background and constant H-flux. After an odd number of T-dualities, correlation functions allow to extract a three-product having a pattern similar to the Moyal-Weyl product. We then focus on the target space and the local appearance of the various fluxes. An algebra based on vector fields is proposed, whose structure functions are given by the fluxes. Jacobi-identities for vector fields allow for the computation of Bianchi-identities. Based on the latter, we give a proof for a special Courant algebroid structure on the generalized tangent bundle, where the fluxes are realized by the commutation relations of a basis of sections. As reviewed in the first part of this work, in the description of non-geometric Q- and R-fluxes, the B-field gets replaced by a bi-vector β, which is supposed to serve as the dual object to B under T-duality. A natural question is about the existence of a differential geometric framework allowing the construction of actions manifestly invariant under coordinate- and gauge transformations, which couple the β-field to gravity. It turns out that Lie algebroids are the right language to answer this question positively. We conclude by giving an outlook on future directions.

description: In industry, many problems are considered as the Decentralized Resource-Constrained Multi-Project Scheduling Problem (DRCMPSP). The existing approaches face problems of formation and choice of bids for distribution of global resources. In this paper, we propose new approaches to solve DRCMPSP based on fragmentation of projects on subprojects and subsequent multicriteria choice of the next subproject for its inclusion in the multi-project schedule. Visualizations of the considered problems are presented.

What About Certificates? Evidence on the Labor Market Returns to Non-Degree Community College Awards in Two States

description: The annual number of certificates (non-degree awards that typically require less time to complete than degrees) awarded by community colleges has increased dramatically since 2000, but relatively little research has been conducted on the economic benefits of certificates in the labor market. Based on detailed student-level information from matched college transcript and employment data in two states, this paper estimates the relationship between earning a certificate and student earnings and employment status after exiting college.

The results indicate that certificates have positive impacts on earnings in both states overall, and in cases where there is no impact on earnings, certificates may nonetheless lead to increased probability of employment or to other benefits. In some cases, certificates appear to promote entry into a student’s desired industry of employment, even if the industry switch is not associated with an increase in earnings on average. In addition, the authors find substantial variation in the returns across fields of study and, more importantly, across specific programs within a particular field. These results suggest that important evidence is lost when information about the benefits of certificate programs are simply averaged together.

description: This report is designed to help improve transfer student outcomes by helping institutional leaders and policymakers better understand current outcomes and providing them with metrics for benchmarking their performance.

The authors propose a common set of metrics for measuring the effectiveness of two- and four-year institutions in enabling degree-seeking students who start college at a community college to transfer to four-year institutions and earn bachelor’s degrees. These include three community college measures—transfer-out rate, transfer-with-award rate, and transfer-out bachelor’s completion rate—and one measure for four-year institutions—transfer-in bachelor’s completion rate. They also examine a fifth measure: the overall rate at which the cohort of students who start at a community college in a given state go on to earn a bachelor’s degree from a four-year institution. Using a rich set of data from the National Student Clearinghouse on more than 700,000 degree-seeking students who first enrolled in community college in 2007, the authors calculated the average outcomes on these measures six years after these students entered college.

Performance on all measures varied widely across individual institutions and states. Institutional characteristics were not strongly correlated with student outcomes at community colleges, suggesting that institutions that serve transfer students well can have better-than-expected outcomes even if they have relatively few resources or more disadvantaged students. Among four-year institutions, transfer students had better outcomes at public institutions, very selective institutions, and institutions with higher socioeconomic status students. Lower income transfer students had worse outcomes than higher income students on almost all measures, though in a few states, the success gap between lower and higher income students was small or nonexistent.

description: We show that oscillation death as a specific type of oscillation suppression, which implies symmetry breaking, can be controlled by introducing time-delayed coupling. In particular, we demonstrate that time delay influences the stability of an inhomogeneous steady state, providing the opportunity to modulate the threshold for oscillation death. Additionally, we find a novel type of oscillation death representing a secondary bifurcation of an inhomogeneous steady state.

description: We consider light propagation through a pair of nonlinear optical waveguides with absorption, placed in a medium with power gain. The active medium boosts the in-phase component of the overlapping evanescent fields of the guides, while the nonlinearity of the guides couples it to the damped out-of-phase component creating a feedback loop. As a result, the structure exhibits stable stationary and oscillatory regimes in a wide range of gain-loss ratios. We show that the pair of actively-coupled ($\mathcal{AC}$) waveguides can act as a stationary or integrate-and-fire comparator sensitive to tiny differences in their input powers.

title: Naval Aviation Squadron Risk Analysis Predictive Bayesian Network Modeling Using Maintenance Climate Assessment Survey Results
Creators: name: Robinson, Harry Michael
Publisher: name: Old Dominion University Libraries
Year: 2014

description: Associated risks in flying have resulted in injury or death to aircrew and passengers, and damage or destruction of the aircraft and its surroundings. Although the Naval Aviation's flight mishap rate declined over the past 60 years, the proportion of human error causal factors has stayed relatively constant at about 80%. Efforts to reduce human errors have focused attention on understanding the aircrew and maintenance actions occurring in complex systems.

One such tool has been the Naval Aviation squadrons' regular participation in survey questionnaires deigned to measure respondent ratings related to personal judgments or perceptions of organizational climate for meeting the extent to which a particular squadron achieved the High Reliability Organization (HRO) criteria of achieving safe and reliable operations and maintenance practices while working in hazardous environments. Specifically, the Maintenance Climate Assessment Survey (MCAS) is completed by squadron maintainers to enable leadership to assess their unit's aggregated responses against those from other squadrons.

Bayesian Network Modeling and Simulation provides a potential methodology to represent the relationships of MCAS results and mishap occurrences that can be used to derive and calculate probabilities of incurring a future mishap. Model development and simulation analysis was conducted to research a causal relationship through quantitative analysis of conditional probabilities based upon observed evidence of previously occurred mishaps. This application would enable Navy and Marine Corps aviation squadron leadership to identify organizational safety risks, apply focused proactive measures to mitigate related hazards characterized by the MCAS results, and reduce organizational susceptibility to future aircraft mishaps.

description: Background: Previous trials have showed a 10–30% rate of inaccuracies on applications to individual residency programs. No studies have attempted to corroborate this on a national level. Attempts by residency programs to diminish the frequency of inaccuracies on applications have not been reported. We seek to clarify the national incidence of inaccuracies on applications to emergency medicine residency programs.

Methods: This is a multi-center, single-blinded, randomized, cohort study of all applicants from LCME accredited schools to involved EM residency programs. Applications were randomly selected to investigate claims of AOA election, advanced degrees and publications. Errors were reported to applicants' deans and the NRMP.

Results: Nine residencies reviewed 493 applications (28.6% of all applicants who applied to any EM program). 56 applications (11.4%, 95%CI 8.6–14.2%) contained at least one error. Excluding "benign" errors, 9.8% (95% CI 7.2–12.4%), contained at least one error. 41% (95% CI 35.0–47.0%) of all publications contained an error. All AOA membership claims were verified, but 13.7% (95%CI 4.4–23.1%) of claimed advanced degrees were inaccurate. Inter-rater reliability of evaluations was good. Investigators were reluctant to notify applicants' dean's offices and the NRMP.

Conclusion: This is the largest study to date of accuracy on application for residency and the first such multi-centered trial. High rates of incorrect data were found on applications. This data will serve as a baseline for future years of the project, with emphasis on reporting inaccuracies and warning applicants of the project's goals.

Concretely, we study the correspondence between the quintessence, tachyon, K-essence, dilaton scalar field and Chaplygin gas model with the new holographic dark energy model in the non-flat Brans-Dicke universe. Furthermore, we reconstruct the potentials and dynamics for these models. By analysis we can show that for new holographic quintessence and Chaplygin gas models, if the related parameters to the potentials satisfy some constraints, the accelerated expansion can be achieved in Brans-Dicke cosmology. Especially the counterparts of fields and potentials in general relativity can describe accelerated expansion of the universe. It is worth stressing that not only can we give some new results in the framework of Brans-Dicke cosmology, but also the previous results of the new holographic dark energy in Einstein gravity can be included as special cases given by us.

description: Honey is a sweet natural product produced by bees. It has many beneficial health promoting effects. The essential and non-essential metals’ contents of bee honey samples collected from Damot Gale district were determined by atomic absorption spectrophotometer. The samples were digested to obtain the essential and non-essential metals by optimum digestion condition. The digestion method for honey analysis was found to be efficient for all in the analyzed metals. The analysis was validated through the recovery experiments showing that a good percentage recovery (95.7-103%). The results obtained from honey samples collected from the bee farmers revealed that the values of pH, moisture and ash content of mid land to be 3.65 ± 0.062, 16.77 ± 0.06 and 0.42 ± 0.006, respectively while the low land part is 3.88 ± 0.057, 16.97 ± 0.034 and 0.46 ± 0.003, respectively. The results of this study revealed that the concentrations of most metals are higher in the honey samples collected from low land part than mid land part within the selected sites. This study’s result was compared with other reported values and found almost comparable. The results of current finding were also compared with international standards set by WHO/FAO and revealed that the levels of some essential and non- essential metals in honey samples were within permissible limits. Therefore, the finding of this study indicated that the honey of the study areas was found safe for consumption regarding studied metal concentration.

Measurements were carried out on GDEs with a Pt loading of 100 µg cm.2 and a catalyst-coated area of 0.5 cm2 in 2 M HClO4. shows that the Potentiostat with the higher compliance voltage of 12 V allows a higher maximum current to flow through the cell. An interesting feature when comparing the curves recorded with the different Potentiostats is that the maximum current in the measurement with the Potentiostat with the lower compliance voltage is given as a plateau, while the Potentiostat with higher compliance voltage is stopping to record current once the compliance voltage is reached.

description: Background: Sodium weighted images can indicate sodium signal intensities from different features in the tumor before and 24 hours following administration of Taxotere.

Aim: To evaluate the association of in vivo intracellular sodium magnetic resonance image intensities with immuno-biomarkers and histopathological features to monitor the early tumor response to Taxotere chemotherapy in Methyl-Nitroso-Urea induced rat xenograft breast tumors.

Methods and Materials: Methyl-Nitroso-Urea (MNU) induced rat xenograft breast tumors were imaged for sodium MRI and compared with tumor histology, immunostaining after 24 hours chemotherapy.

Results: Sodium MRI signal intensities represented sodium concentrations. Excised tumor histological sections showed different in vitro histological end points i.e. single strand DNA content of cell nuclei during cell cycle (G1/S-G2/M), distinct S or M histograms (Feulgen labeling to nuclear DNA content by CAS 200), mitotic figures and apoptosis at different locations of breast tumors. Necrosis and cystic fluid appeared gray on intracellular (IC) sodium images while apoptosis rich regions appeared brighter on IC sodium images. After 24 hours Taxotere-treated tumors showed lower 'IC/EC ratio' of viable cells (65–76%) with higher mitotic index; apoptotic tumor cells at high risk due to cytotoxicity (>70% with high apoptotic index); reduced proliferation index (270 vs 120 per high power field) associated with enhanced IC sodium in vivo MR image intensities and decreased tumor size (3%; p < 0.001; n = 16) than that of pre-treated tumors. IC-Na MR signal intensities possibly indicated Taxotere chemosensitivity response in vivo associated with apoptosis and different pre-malignant features within 24 hours of exposure of cancer cells to anti-neoplastic Taxotere drug.

Conclusion: Sodium MRI imaging may be used as in vivo rapid drug monitoring method to evaluate Taxotere chemosensitivity response associated with neoplasia, apoptosis and tumor histology features.

description: The fast shocks that characterize supernova remnants heat circumstellar and ejecta material to extremely high temperatures, resulting in significant X-ray emission. The X-ray spectrum from an SNR carries a wealth of information about the temperature and ionization state of the plasma, the density distribution of the postshock material, and the composition of the ejecta. This, in turn, places strong constraints on the properties of the progenitor star, the explosive nucleosynthesis that produced the remnant, the properties of the environment into which the SNR expands, and the effects of particle acceleration on its dynamical evolution. Here I present results from X-ray studies SNRs in various evolutionary states, and highlight key results inferred from the thermal emission.

description: Background: The rapid urban malaria appraisal (RUMA) methodology aims to provide a cost-effective tool to conduct rapid assessments of the malaria situation in urban sub-Saharan Africa and to improve the understanding of urban malaria epidemiology.

Methods: This work was done in Yopougon municipality (Abidjan), Cotonou, Dar es Salaam and Ouagadougou. The study design consists of six components: 1) a literature review, 2) the collection of available health statistics, 3) a risk mapping, 4) school parasitaemia surveys, 5) health facility-based surveys and 6) a brief description of the health care system. These formed the basis of a multi-country evaluation of RUMA's feasibility, consistency and usefulness.

Results: A substantial amount of literature (including unpublished theses and statistics) was found at each site, providing a good overview of the malaria situation. School and health facility-based surveys provided an overview of local endemicity and the overall malaria burden in different city areas. This helped to identify important problems for in-depth assessment, especially the extent to which malaria is over-diagnosed in health facilities. Mapping health facilities and breeding sites allowed the visualization of the complex interplay between population characteristics, health services and malaria risk. However, the latter task was very time-consuming and required special expertise. RUMA is inexpensive, costing around 8,500–13,000 USD for a six to ten-week period.

Conclusion: RUMA was successfully implemented in four urban areas with different endemicity and proved to be a cost-effective first approach to study the features of urban malaria and provide an evidence basis for planning control measures.

description: Background: To make inferences about brain structures or activity across multiple individuals, one first needs to determine the structural correspondences across their image data. We have recently developed Mindboggle as a fully automated, feature-matching approach to assign anatomical labels to cortical structures and activity in human brain MRI data. Label assignment is based on structural correspondences between labeled atlases and unlabeled image data, where an atlas consists of a set of labels manually assigned to a single brain image. In the present work, we study the influence of using variable numbers of individual atlases to nonlinearly label human brain image data. Methods: Each brain image voxel of each of 20 human subjects is assigned a label by each of the remaining 19 atlases using Mindboggle. The most common label is selected and is given a confidence rating based on the number of atlases that assigned that label. The automatically assigned labels for each subject brain are compared with the manual labels for that subject (its atlas). Unlike recent approaches that transform subject data to a labeled, probabilistic atlas space (constructed from a database of atlases), Mindboggle labels a subject by each atlas in a database independently. Results: When Mindboggle labels a human subject's brain image with at least four atlases, the resulting label agreement with coregistered manual labels is significantly higher than when only a single atlas is used. Different numbers of atlases provide significantly higher label agreements for individual brain regions. Conclusion: Increasing the number of reference brains used to automatically label a human subject brain improves labeling accuracy with respect to manually assigned labels. Mindboggle software can provide confidence measures for labels based on probabilistic assignment of labels and could be applied to large databases of brain images.
