Hospitality: Areas That Are Effective in Creating a Desire for a Visitor to Connect to Our Redeemer Lutheran Church
This major applied project explores hospitality offered by the local congregation. Biblical hospitality is implicitly and explicitly commanded in scripture. Balancing the Missio Dei and two kinds of righteousness will keep us on the straight and narrow theologically when pursuing hospitality.
When churches offer hospitality, we are feeding, clothing, visiting, providing, and welcoming our neighbor. Our Redeemer wants to continue serving the community as a family-oriented, mission focused, hospitable congregation. We are doing the feeding, clothing, and providing through many efforts in the community. We are active with the local homeless shelter and crisis center. For the MAP, we wanted to discover what areas of hospitality are effective in creating a desire for visitors to have a further connection to the congregation. Through this particular study, we want to better understand our hospitality of welcoming and visiting. Both secular and sacred sources are explored as resources. To offer hospitality means preparation on our part.
Secret shoppers were utilized to measure the effectiveness of Our Redeemer’s hospitality. Through secret visits by individuals that fit the prescribed criteria and follow-up personal interviews, an image of Our Redeemer’s friendliness and expression of hospitality has been formed. As a result of this MAP the congregation will address facility issues and continually build a culture of hospitality. At Our Redeemer, we are about “Equipping Disciples to Make Disciples for Jesus!” Since that is true, it can be said that at Our Redeemer, we are about hospitality! As Christians, we all need to practice hospitality
Extended trigonometric Cherednik algebras and nonstationary Schr\"odinger equations with delta-potentials
We realize an extended version of the trigonometric Cherednik algebra as
affine Dunkl operators involving Heaviside functions. We use the quadratic
Casimir element of the extended trigonometric Cherednik algebra to define an
explicit nonstationary Schr\"odinger equation with delta-potential. We use
coordinate Bethe ansatz methods to construct solutions of the nonstationary
Schr\"odinger equation in terms of generalized Bethe wave functions. It is
shown that the generalized Bethe wave functions satisfy affine difference
Knizhnik-Zamolodchikov equations in their spectral parameter. The relation to
the vector valued root system analogs of the quantum Bose gas on the circle
with pairwise delta-function interactions is indicated.Comment: 23 pages; Version 2: expanded introduction and misprints correcte
The Reasonable Effectiveness of Randomness in Scalable and Integrative Gene Regulatory Network Inference and Beyond
Gene regulation is orchestrated by a vast number of molecules, including transcription factors and co-factors, chromatin regulators, as well as epigenetic mechanisms, and it has been shown that transcriptional misregulation, e.g., caused by mutations in regulatory sequences, is responsible for a plethora of diseases, including cancer, developmental or neurological disorders. As a consequence, decoding the architecture of gene regulatory networks has become one of the most important tasks in modern (computational) biology. However, to advance our understanding of the mechanisms involved in the transcriptional apparatus, we need scalable approaches that can deal with the increasing number of large-scale, high-resolution, biological datasets. In particular, such approaches need to be capable of efficiently integrating and exploiting the biological and technological heterogeneity of such datasets in order to best infer the underlying, highly dynamic regulatory networks, often in the absence of sufficient ground truth data for model training or testing. With respect to scalability, randomized approaches have proven to be a promising alternative to deterministic methods in computational biology. As an example, one of the top performing algorithms in a community challenge on gene regulatory network inference from transcriptomic data is based on a random forest regression model. In this concise survey, we aim to highlight how randomized methods may serve as a highly valuable tool, in particular, with increasing amounts of large-scale, biological experiments and datasets being collected. Given the complexity and interdisciplinary nature of the gene regulatory network inference problem, we hope our survey maybe helpful to both computational and biological scientists. It is our aim to provide a starting point for a dialogue about the concepts, benefits, and caveats of the toolbox of randomized methods, since unravelling the intricate web of highly dynamic, regulatory events will be one fundamental step in understanding the mechanisms of life and eventually developing efficient therapies to treat and cure diseases

Principles of Laser Micro Sintering
Laser Micro Sintering was introduced to the international community of freeform fabrication
engineers in 2003 and has since been employed for a variety of applications. It owes its unique
features to certain effects of q-switched pulses that formerly had been considered detrimental in
selective laser sintering. Besides sub-micrometer sized powders also materials with grain sizes
of 1-10 micrometers can be sintered. Surface and morphology of the product are influenced by
grain size and process environment. First results have been achieved with processing ceramic
materials.
A comprehensive overview of the process and the features is given supported by
experimental evidence. Routes of further development are indicated.Mechanical Engineerin
Liquid Oxygen Liquid Acquisition Device Bubble Point Tests with High Pressure LOX at Elevated Temperatures
When transferring propellant in space, it is most efficient to transfer single phase liquid from a propellant tank to an engine. In earth s gravity field or under acceleration, propellant transfer is fairly simple. However, in low gravity, withdrawing single-phase fluid becomes a challenge. A variety of propellant management devices (PMD) are used to ensure single-phase flow. One type of PMD, a liquid acquisition device (LAD) takes advantage of capillary flow and surface tension to acquire liquid. The present work reports on testing with liquid oxygen (LOX) at elevated pressures (and thus temperatures) (maximum pressure 1724 kPa and maximum temperature 122K) as part of NASA s continuing cryogenic LAD development program. These tests evaluate LAD performance for LOX stored in higher pressure vessels that may be used in propellant systems using pressure fed engines. Test data shows a significant drop in LAD bubble point values at higher liquid temperatures, consistent with lower liquid surface tension at those temperatures. Test data also indicates that there are no first order effects of helium solubility in LOX on LAD bubble point prediction. Test results here extend the range of data for LOX fluid conditions, and provide insight into factors affecting predicting LAD bubble point pressures

Palladium-Catalyzed Methylation of Aryl, Heteroaryl, and Vinyl Boronate Esters.
A method for the direct methylation of aryl, heteroaryl, and vinyl boronate esters is reported, involving the reaction of iodomethane with aryl-, heteroaryl-, and vinylboronate esters catalyzed by palladium and PtBu2Me. This transformation occurs with a remarkably broad scope and is suitable for late-stage derivatization of biologically active compounds via the boronate esters. The unique capabilities of this method are demonstrated by combining carbon-boron bond-forming reactions with palladium-catalyzed methylation in a tandem transformation
An assessment of the effects of the 2002 food crisis on children's health in Malawi
In 2002 Malawi experienced a serious shortage of cereals due to adverse climatic conditions. The World Food Programme assumed that about 2.1 to 3.2 million people were threatened of starvation at that time. However, not much research has been undertaken to investigate the actual consequences of this crisis. In particular, little is known about how the crisis affected the health status of children. Obviously, quantifying the health impact of such a crisis is a serious task given the lack of data and the more general problem of relating outcomes to specific shocks and policies.
In this paper a difference-in-difference estimator is used to quantify the impact of the food crisis on the health status of children. The findings suggest that at least in the short run, there was neither a significant impact on child mortality nor on malnutrition. This would suggest that the shock might have been less severe than initially assumed and that the various policy interventions undertaken at the time have been effective or at least sufficient to counteract the immediate effects of the crisis
