Standardized Practice, Individualized Care: Exploring Best Practices for Effective Delivery of Education to Families of Newly Diagnosed Pediatric Cancer Patients
Creators: name: Duncan, Julia

Year: 2020

description: Over 15,000 cases of pediatric cancer arise each year, and are the second leading cause of death in children. While this diagnosis is completely life-changing, health education is a crucial element of care that can reduce the risk of patients and families developing anxiety and depression, if the teaching is completely understood and comprehended. To date, there are no evidence-based guidelines in place to ensure consistent and adequate teaching. The Children’s Oncology Group (COG) recognized this gap so vast, that the topic was classified as a major need to address in their five-year blueprint, and conferences were held by the Nursing Discipline in 2016 with the sole purpose of formulating evidence-based guidelines. Nurses are considered prime educators, given their constant presence at the bedside to provide informal teaching, that supplements formal teaching. A review of the literature was conducted in order to synthesize available evidence to formulate standardized guidelines for delivering patient and family education following a pediatric cancer diagnosis. This review yielded both family and nurse perspectives of the following aspects of cancer diagnosis-related patient and family education: topics that are essential to teach, educational format and timing of education following the initial diagnosis. It is essential that information provided to patients and families is standardized, while the delivery of the teaching is individualized.

Year: 2015

description: Analyzing impact of macroeconomic instability on economic growth and private capital accumulation from the year 1974 to 2013 is the main objective of the study. Rather than using one variable as a proxy for macroeconomic instability, the researcher attempts to calculate macroeconomic instability index by using four variables: budget deficit, public debt, exchange rate variability and inflation by utilizing UNDP HDI methodology. In specification of regression equations, endogenous growth model and accelerator model are used for growth and capital accumulation equation respectively. Empirical analysis has been performed by using Johansson maximum likelihood method, the result shows that there is a long run relationship among the variables entered in both models. Both the long run and short run result shows that, macroeconomic instability has a detrimental effect on both economic growth and private capital accumulation. Based on the finding, the major policy implication of this study is that, poor management of macroeconomic with the adoption of incorrect and illogical fiscal and monetary policies and passive reaction against shocks will intensify the macroeconomic instability. Due to this, the way of reaction to the shocks is very important.

description: This work proposes a decentralized, iterative, Bayesian algorithm called CB-DSBL for in-network estimation of multiple jointly sparse vectors by a network of nodes, using noisy and underdetermined linear measurements. The proposed algorithm exploits the network wide joint sparsity of the un- known sparse vectors to recover them from significantly fewer number of local measurements compared to standalone sparse signal recovery schemes. To reduce the amount of inter-node communication and the associated overheads, the nodes exchange messages with only a small subset of their single hop neighbors. Under this communication scheme, we separately analyze the convergence of the underlying Alternating Directions Method of Multipliers (ADMM) iterations used in our proposed algorithm and establish its linear convergence rate. The findings from the convergence analysis of decentralized ADMM are used to accelerate the convergence of the proposed CB-DSBL algorithm. Using Monte Carlo simulations, we demonstrate the superior signal reconstruction as well as support recovery performance of our proposed algorithm compared to existing decentralized algorithms: DRL-1, DCOMP and DCSP.

description: A lot of studies on the summary measures of predictive strength of categorical response models consider the likelihood ratio index (LRI), also known as the McFadden-$R^2$, a better option than many other measures. We propose a simple modification of the LRI that adjusts for the effect of the number of response categories on the measure and that also rescales its values, mimicking an underlying latent measure. The modified measure is applicable to both binary and ordinal response models fitted by maximum likelihood. Results from simulation studies and a real data example on the olfactory perception of boar taint show that the proposed measure outperforms most of the widely used goodness-of-fit measures for binary and ordinal models. The proposed $R^2$ interestingly proves quite invariant to an increasing number of response categories of an ordinal model.

description: We show that the moduli spaces of stable sheaves on projective schemes admit certain non-commutative structures, which we call quasi NC structures, generalizing Kapranov's NC structures. The completion of our quasi NC structure at a closed point of the moduli space gives a pro-representable hull of the non-commutative deformation functor of the corresponding sheaf developed by Laudal, Eriksen, Segal and Efimov-Lunts-Orlov. We also show that the framed stable moduli spaces of sheaves have canonical NC structures.

description: Major League Baseball (MLB) has enjoyed steady financial growth in the recent past, which is largely attributed to media and sponsorship deals. Despite this growth, the league is losing favor with younger generations, namely Generation Z, and attendance rates are falling to historic lows with each new season. In order to sustain the financial growth of its league, MLB must better understand the attitudes and perceptions of Generation Z and thereby positively influence Generation Z attendance rates. To address these concerns, I have conducted 2 focus groups with Generation Z undergraduate students at the University of North Carolina at Chapel Hill that illustrate Generation Z’s attitudes, beliefs, and feelings about MLB, attending sporting events, and influences of their consumer behavior. With the participants’ insights, I have considered a few key marketing recommendations that have the potential to help usher in a new generation of MLB fans.

description: With humans interacting with AI-based systems at an increasing rate, it is necessary to ensure the artificial systems are acting in a manner which reflects understanding of the human. In the case of humans and artificial AI agents operating in the same environment, we note the significance of comprehension and response to the actions or capabilities of a human from an agent's perspective, as well as the possibility to delegate decisions either to humans or to agents, depending on who is deemed more suitable at a certain point in time. Such capabilities will ensure an improved responsiveness and utility of the entire human-AI system. To that end, we investigate the use of cognitively inspired models of behavior to predict the behavior of both human and AI agents. The predicted behavior, and associated performance with respect to a certain goal, is used to delegate control between humans and AI agents through the use of an intermediary entity. As we demonstrate, this allows overcoming potential shortcomings of either humans or agents in the pursuit of a goal.

description: Tysonite structure fluorides doped with divalent cations, represented by Ce0.95Ca0.05F2.95, are a class of good F- ion conductors together with fluorite-structured compounds. Computational understanding of the F- conduction process is difficult because of the complicated interactions between three symmetrically distinct F sites and the experimentally observed change in the F diffusion mechanism slightly above room temperature, effectively making first principles molecular dynamics (FP-MD) simulations, which are often conducted well above the transition temperature, useless when analyzing behavior below the transition point. Neural network potential (NNP) MD simulations showed that the F diffusion coefficient is higher when the divalent dopant cation size is similar to the trivalent cation size. The diffusion behavior of F in different sites changes at roughly 500 K in Ce0.95Ca0.05F2.95 because only the F1 site sublattice contributes to F diffusion below this temperature but the remaining F2 and F3 sublattices becomes gradually active above this temperature. The paradox of higher diffusion coefficients in CeF3-based compounds than similar LaF3-based compounds even though the lattice parameters are larger in the latter may be caused by a shallower potential of Ce and F in CeF3 compared to the LaF3 counterparts.

description: Based on self-consistent field (SCF) atomic mean-field (amf) quantities, we present two simple, yet computationally efficient and numerically accurate matrix-algebraic approaches to correct both scalar-relativistic \textit{and} spin-orbit two-electron picture-change effects (PCE) arising within an exact two-component (X2C) Hamiltonian framework. Both approaches, dubbed amfX2C and e(xtended)amfX2C, allow us to uniquely tailor PCE corrections to mean-field models, $viz.$ Hartree-Fock or Kohn-Sham DFT, in the latter case also avoiding the need of a point-wise calculation of exchange-correlation PCE corrections. We assess the numerical performance of these PCE correction models on spinor energies of group-18 (closed-shell) and group-16 (open-shell) diatomic molecules, achieving a consistent $\approx\!10^{-5}$ Hartree accuracy compared to reference four-component data. Additional tests include SCF calculations of molecular properties such as absolute contact density and contact density shifts in copernicium fluoride compounds (CnF$_{n}$, n=2,4,6), as well as equation-of-motion coupled cluster calculations of X-ray core ionization energies of $5d$ and $6d$-containing molecules, where we observe an excellent agreement with reference data. To conclude, we are confident that our (e)amfX2C PCE correction models constitute a fundamental milestone towards a universal and reliable relativistic two-component quantum chemical approach, maintaining the accuracy of the parent four-component one at a fraction of its computational cost.

description: While publishing articles in all fields of science and research is a common practice, it is less common in the area of metadata and data management, especially in the DDI community. This can be seen as problematic because gained insights tend to disappear after projects are offline and the next similar project has to start from the very beginning – which is a common (and perhaps preferred) practice for most software engineers. But: If one would subsume metadata and data management under science, sustainable research would look different and last but not least the principle “publish or perish” is relevant for many involved experts, too. This presentation will give an overview of the current status of DDI-related publications. Furthermore the ongoing work of a related working group of the DDI Alliance will be described.

description: A linearly ordered (LO) $k$-colouring of an $r$-uniform hypergraph assigns an integer from $\{1, \ldots, k \}$ to every vertex so that, in every edge, the (multi)set of colours has a unique maximum. Equivalently, for $r=3$, if two vertices in an edge are assigned the same colour, then the third vertex is assigned a larger colour (as opposed to a different colour, as in classic non-monochromatic colouring). Barto, Battistelli, and Berg [STACS'21] studied LO colourings on $3$-uniform hypergraphs in the context of promise constraint satisfaction problems (PCSPs). We show two results. First, given a 3-uniform hypergraph that admits an LO $2$-colouring, one can find in polynomial time an LO $k$-colouring with $k=O(\sqrt[3]{n \log \log n / \log n})$. Second, given an $r$-uniform hypergraph that admits an LO $2$-colouring, we establish NP-hardness of finding an LO $k$-colouring for every constant uniformity $r\geq k+2$. In fact, we determine relationships between polymorphism minions for all uniformities $r\geq 3$, which reveals a key difference between $r

description: We describe new arithmetic invariants for pairs of torus orbits on groups isogenous to an inner form of $\mathbf{PGL}_n$ over a number field. These invariants are constructed by studying the double quotient of a linear algebraic group by a maximal torus. Using the new invariants we significantly strengthen results towards the equidistribution of packets of periodic torus orbits on higher rank $S$-arithmetic quotients. Packets of periodic torus orbits are natural collections of torus orbits coming from a single adelic torus and are closely related to class groups of number fields. The distribution of these orbits is akin to the distribution of integral points on homogeneous algebraic varieties with a torus stabilizer. The proof combines geometric invariant theory, Galois actions, local arithmetic estimates and homogeneous dynamics.

progressive supranuclear palsy

description: Cognitive impairment is integral to the syndrome of progressive supranuclear palsy. It is most commonly described as a frontal dysexecutive syndrome but other impairments include apathy, impulsivity, visuospatial and memory functions. Cognitive dysfunction may be exacerbated by mood disturbance, medication and communication problems. In this review we advocate an individualized approach to managing cognitive impairment in progressive supranuclear palsy with the education of caregivers as a central component. Specific cognitive and behavioral treatments are complemented by treatment of mood disturbances, rationalizing medications and a patient-centered approach to communication. This aims to improve patients' quality of life, reduce carer burden and assist people with progressive supranuclear palsy in decisions about their life and health, including discussions of feeding and end-of-life issues.

description: Here we study the two-periodic weighted dimer model on the Aztec diamond graph. In the thermodynamic limit when the size of the graph goes to infinity while weights are fixed, the model develops a limit shape with frozen regions near corners, a flat ``diamond'' in the center with a noncritical (ordered) phase, and a disordered phase separating this diamond and the frozen phase. We show that in the mesoscopic scaling limit, when weights scale in the thermodynamic limit such that the size of the ``flat diamond'' is of the same order as the correlation length inside the diamond, fluctuations of the height function are described by a new process. We compute asymptotics of the inverse Kasteleyn matrix for vertices in a local neighborhood in this mesoscopic limit.

The Effects of a Professional Development Program on Teacher Classroom Literacy Practices

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Reading proficiency is a skill that is developed and acquired in student's earliest schooling years, but one that has a lifelong impact. The Targeted Reading Intervention is a professional development program for rural kindergarten and first-grade teachers which provides teachers with training and on-going literacy coaching in evidenced-based practices to support struggling early readers. The TRI has been replicated in a series of Randomized Controlled Trials and has been found to increase students' decoding, word recognition, and reading comprehension skills. This study focuses on classroom teacher's implementation of evidence-based phonics, vocabulary, and reading comprehension practices. The current study uses data from the TRI's teacher questionnaire, in which teachers self-reported their classroom practices, to examine the effects of the professional development program on teacher's classroom literacy practices. Six items from the TRI teacher questionnaire were used as measures of teacher implementation of evidence-based phonics, vocabulary, and reading comprehension practices in the classroom. Multiple linear regression analyses were run on these six items to examine the effect of the TRI on classroom teachers' practices. The results of this study found that the TRI professional development program was ineffective at changing classroom teachers' phonics, vocabulary, and reading comprehension practices. These results indicate that teachers are more likely to rely on their professional wisdom and experience to inform their classroom practices than evidence-based practices taught in professional development.

description: In this work, we investigate the rotational dynamics of the ginger-shaped near-Earth asteroid 4179 Toutatis, which was closely observed by Chang'e-2 at a distance of $770\pm120~$ meters from the asteroid's surface during the outbound flyby \citep{Huang2013} on 13 December 2012. A sequence of high-resolution images was acquired during the flyby mission. In combination with ground-based radar observations collected over the last two decades, we analyze these flyby images and determine the orientation of the asteroid at the flyby epoch. The 3-1-3 Euler angles of the conversion matrix from the J2000 ecliptic coordinate system to the body-fixed frame are evaluated to be $-20.1^\circ\pm1^\circ$, $27.6^\circ\pm1^\circ$ and $42.2^\circ\pm1^\circ$, respectively. The least-squares method is utilized to determine the rotational parameters and spin state of Toutatis. The characteristics of the spin-state parameters and angular momentum variations are extensively studied using numerical simulations, which confirm those reported by \citet{Takahashi2013}. The large amplitude of Toutatis' precession is assumed to be responsible for its tumbling attitude as observed from Earth. Toutatis' angular momentum orientation is determined to be described by $λ_{H}=180.2^{+0.2^\circ}_{-0.3^\circ}$ and $β_{H}=-54.75^{+0.15^\circ}_{-0.10^\circ}$, implying that it has remained nearly unchanged for two decades. Furthermore, using Fourier analysis to explore the change in the orientation of Toutatis' axes, we reveal that the two rotational periods are 5.38 and 7.40 days, respectively, consistent with the results of the former investigation. Hence, our investigation provides a clear understanding of the state of the rotational dynamics of Toutatis.

In preparation of ALMA, we have carried out a large number of observational tests and state-of-the-art radiation MHD simulations. Here we review the best available observations of the Sun at millimeter wavelengths.Using state of the art radiation MHD simulations of the solar atmosphere we demonstrate the huge potential of ALMA observations for uncovering the nature of the solar chromosphere. We show that ALMA will not only provide a reliable probe of the thermal structure and dynamics of the chromosphere, it will also open up a powerful new diagnostic of magnetic field at chromospheric heights, a fundamentally important, but so far poorly known parameter.

description: We present non- and ultra-relativistic Jackiw-Teitelboim (JT) supergravity as metric BF theories based on the extended Newton-Hooke and extended AdS Carroll superalgebras in two spacetime dimensions, respectively. The extended Newton-Hooke structure, and, in particular, the invariant metric necessary for the BF construction of non-relativistic JT supergravity, is obtained by performing an expansion of the $\mathcal{N}=2$ AdS$_2$ superalgebra. Subsequently, we introduce the extended AdS$_2$ Carroll superalgebra, and the associated invariant metric, as a suitable redefinition of the extended Newton-Hooke superalgebra. The mapping involved can be seen as the supersymmetric extension of the duality existing at the purely bosonic level between the extended Newton-Hooke algebra with (positive) negative cosmological constant and the extended (A)dS Carroll algebra in two dimensions. Finally, we provide the Carrollian JT supergravity action in the BF formalism. Moreover, we show that both the non-relativistic and the ultra-relativistic theories presented can also be obtained by direct expansion of $\mathcal{N}=2$ JT supergravity.

mvn-analysis: Software to Characterize the Structure and Fluid Flow Forces within Engineered Microvascular Networks
Creators: name: Armstrong, Ryan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020
Subjects: Computational biology

description: Microvascular networks consist of interconnected blood vessels < 150 um in diameter and are responsible for transporting metabolites and nutrients to the body's cells. New microvascular blood vessels are formed from existing vessels through the process of angiogenesis. While many chemical gradients controlling angiogenesis are known, the role of hemodynamic forces--such as wall shear stress and pressure--are less understood. Controlling angiogenesis is clinically relevant and could be uses in the treatment of cancer, ischemic heart disease, peripheral arterial disease, and others. However, the small physical scale and large topological complexity of microvascular networks makes researching the effects of fluid flow forces on angiogenesis difficult. Therefore, we created software capable of characterizing the structure and fluid flow forces of engineered microvascular networks. Specifically, we demonstrate feasibility to obtain computational volume meshes of the network lumens which can be used in existing fluid solvers to obtain velocity, pressure, and wall shear stress distributions for a microvasular network. Further, the developed software generates physiologically relevant graphical (nodes and edges) and numerical outputs. These outputs describe a network's segment lengths, radii, surface areas, volumes, contraction factors, fractal dimensions, connectivity, anisotropy, vessel density, and distance of non-vascularized areas to a vessel wall. Using these outputs, we compared microvasular networks grown in low-nutrient and static storage conditions to networks grown in standard nutrient and dynamic storage conditions. Within the low-nutrient and static networks, we observed a decrease in vessel density but a potential maintenance of support to nearby tissue. Further, the  analysis yielded a linear relationship between segment radii and nutrient concentration that could be used to manufacture micrvascular networks at desired average segment radii. Ultimately, the software is designed to relate fluid flow forces to angiogenesis and inform engineering decisions when creating microvascular networks.

description: We study spatial discretizations of dynamical systems: is it possible to recover some dynamical features of a system from numerical simulations? Here, we tackle this issue for the simplest algorithm possible: we compute long segments of orbits with a fixed number of digits. We show that for every $r\ge 1$, the dynamics of the discretizations of a $C^r$ generic conservative diffeomorphism of the torus is very different from that observed in the $C^0$ regularity. The proof of our results involves in particular a local-global formula for discretizations, as well as a study of the corresponding linear case, which uses ideas from the theory of quasicrystals.

description: Es werden in der Forschung-und Entwicklungsabteilung des Campus02 verschiedenste Platinen entwickelt und produziert. Die Platinen müssen nach der Fertigung programmiert werden. Dies gestaltet sich als sehr umständlich und zeitraubend, da es keine Möglichkeit gibt, die einzelnen Platinen zu fixieren und in weiterer Folge zu programmieren sowie zu testen. Ziel dieser Arbeit ist es, ein Prüfgerät zu entwickeln, welches es ermöglicht, verschiedenste Platinenarten und -formen zu fixieren sowie diese anschließend zu programmieren und anhand unterschiedlicher Parameter zu überprüfen. Für die Konstruktion des Prüfgerätes wird das Programm „SOLIDWORKS“ verwendet. Es wird in weiterer Folge ein Konzept erarbeitet, welches es ermöglicht, verschiedenste Platinenformen aufzunehmen und zu testen. Besondere Aufmerksamkeit wird zugleich der Auswahl des Kontaktierungsverfahrens gewidmet, da dies ein Schlüsselfaktor im Sektor der Platinen-Prüfung ist. Es stellte sich nach einer Analyse der gängigsten Methoden heraus, dass eine Kontaktierung mittels Federkontaktstiften am besten für diese Anwendung geeignet ist. In weiterer Folge wird ein Programm mit „LabVIEW“ erzeugt, welches es erlaubt, Strom- und Spannungsmessungen der zu prüfenden Platine durchzuführen. Das Weitern wird das Programm zur Bedienung des Prüfgerätes verwendet. Im Anschluss werden weitere Ausbaustufen und Erweiterungspläne für das Prüfgerät erläutert, die sich auf die bereits gesammelten Erfahrungen der ersten, mit dem Prüfgerät durchgeführten Testaufbauten beziehen.

The aim of this work is to develop a test device that allows different types of boards to fasten types and shapes, and then to program them and check them using various parameters. For the construction of the tester the program SOLIDWORKS is used. Hence a concept is developed, which makes it possible to record and test various forms of boards. Special attention is also given to the selection of the contacting method, as this is a key factor in the board testing sector. After the analysis of the most common methods, it turned out that contacting by means of spring contact pins is best suited for this application. Consequently, a program with LabVIEW is generated, which allows to perform current and voltage measurements, and the operation of the test device takes over. Subsequently, further expansion stages and expansion plans for the testing device are explained, which refer to the experience already gained from the first test setups performed with the test device.

description: A finite subset $M \subset \mathbb{R}^d$ is basic, if for any function $f \colon M \to \mathbb{R}$ there exists a collection of functions $f_1, \ldots, f_d \colon \mathbb{R} \to \mathbb{R}$ such that for each element $(x_1, \ldots, x_d)\in M$ we have $f(x_1, \ldots, x_d) = f_1(x_1) + \ldots + f_d(x_d)$. For certain finite sets, we prove a criterion for a set to be basic, and we show that it cannot be extended to the general case. In addition, we interpret the above criterion in terms of doubly-weighted graphs and give an estimation for the number of elements in certain basic and non-basic subsets.

description: Background: Tuberculosis (Tb) is major cause of morbidity and mortality, for millions of peoples worldwide. Of the different risk factors associated with Tb development and progress, deficiency of micronutrients (vitamins and minerals), mentioned one. In this regards association of micronutrients during development of Tb and then after Tb treatments scarcely found in Ethiopia. Objective: To assess the level of micronutrients (Vitamin A, Vitamin B12 and Iron) among M. tuberculosis patients with and without HIV confection at baseline and after anti TB treatment. Material and method: This study was conduct on serum samples, collected from M.TB patients with and without HIV infection, attending at different health centers in Addis Ababa. The collected samples were stored at EPHI at - 800 C, for about 10 years. Convenient sampling method used to select TB only (87), TB-HIV confection (57), latent TB (25) and healthy controls (21). Socio-demographic data was collected from the previously collected log book. The concentration of Iron and Vitamin B12 was measured by using chemiluminesense method; whereas concentration of retinol measured by using HPLC method. The collected data enter and analyzed by using SPSS statistical software version 20. P-values less than 0.05 considered as statistical significant.
Check Yourself Before You Wreck Yourself: Evaluating for Inclusive and Equitable Themes in Online Resources for Information Technology Competency Tests

description: This research study focused on online resources of information technology competency tests. I used online resources of a fellow SILS student’s research project developing self-guided learning modules to lower the barrier of entry for incoming students required to take the information technology competency test at the School of Information and Library Science at UNC. I used those resources and existing online resources from the current competency test and developed short working guidelines by using evaluation tools analyzing inclusive and equitable themes of accessibility, readability, and learning approaches. The results indicated that despite great value in utilizing evaluation tools, algorithms are insufficient in determining what is inclusive and equitable. Human intervention and involvement can make the biggest impact in deciding how online resources are evaluated in order to reduce or eliminate unnecessary barriers for the incoming students.

description: Mit der vierten Entwicklungsstufe der industriellen Produktion, der sogenannten Industrie 4.0 und mit dem Beginn des Zeitalters der Digitalisierung, hat sich die Knapp AG diesen beiden Themen angenommen. In Bezug auf die globale Warenverfolgung via automatischer Identifikation und Datenerfassung, wird diese Thematik anhand dieser wissenschaftlichen Arbeit behandelt. Diese wissenschaftliche Arbeit soll Aufschlüsse darüber geben, welche Arten von Auto ID für die KNAPP AG in Betracht gezogen werden können und was dies für eine potentielle praktische Umsetzung bedeutet. Zudem soll auch die Frage geklärt werden, wie und ob Umgebungs- und Produktionseinflüsse auf die einzelnen Auto ID Arten sowie die Verfahren mögliche negative Eingriffe hervorrufen könnten. Eine weitere Anforderung an die Knapp AG ist das unternehmerische Wachstum welche zufolge hat, dass eine Umstellung von der herkömmlichen manuellen Warenidentifikation auf eine innerbetriebliche automatisierte Warenverfolgung sowie Warenbereitstellung erzielt werden muss. Abschließend soll diese wissenschaftliche Arbeit die Grundzüge und damit ein allgemeines Verständnis für die Auto ID in der intralogistischen Umgebung der Knapp AG, sowie die unterschiedlichen Technologien, Verfahren und Anwendungen welche zur Realisierung und Umsetzung dieser benötigt wird, vermitteln.
description: The fourth development stage of industrial production, the so-called Industry 4.0 and the beginning of the age of digitization, Knapp AG has taken up these two topics. About the global tracking of goods via automatic identification and data collection (Auto ID), to be of great interest. This topic will be dealt within based on this scientific work. This scientific work should provide information about which types of Auto ID can be considered for KNAPP AG and what potential practical implementation could look like. In addition, the following questions should also be clarified: how and whether environmental and production influences on the individual Auto ID types and procedures cause possible negative interventions. Another requirement for Knapp AG is the entrepreneurial growth which has led to a shift from traditional manual goods identification to in-house automated tracking and provision of goods. Finally, this scientific work should convey the fundamentals and thus a general understanding of the Auto ID in the intralogistics environment of Knapp AG as well as the different technologies, procedures and applications needed for the realization and implementation of these types.

description: Unions and right to work laws have been a contentious subject since the passage of the Taft-Hartley Act. While the debate spans many decades most of the research on the topic has focused primarily on individual level effects. Using the synthetic control method, and the state of Wisconsin as a case study, this paper analyzes the state level economic effects of a RTW law. The results show no effect across the Housing Price Index, GDP, manufacturing wages, or income per capita. This calls into question the purpose and worth of RTW laws.

description: We present the {\tt KKMCee 5.00.2} Monte Carlo event generator for lepton and quark pair production for the high energy electron-positron annihilation process. It is still the most sophisticated event generator for such processes. Its entire source code is re-written in the modern C++ language. It reproduces all features of the older \kkmc\ code in Fortran 77. However, a number of improvements in the Monte Carlo algorithm are also implemented. Most importantly, it is intended to be a starting point for the future improvements, which will be mandatory for the future high precision lepton collider projects. As in the older version, in addition to higher order QED corrections, it includes so-called \order{α^{1.5}} genuine weak corrections using a version of the classic {\tt DIZET} library and polarized $τ$ decays using {\tt TAUOLA} program. Both {\tt DIZET} and {\tt TAUOLA} external libraries are still in Fortran 77. In addition, a {\tt HEPMC3} interface to other MC programs, like parton showers and detector simulation, replaces the older {\tt HepEvt} interface. The {\tt HEPMC3} interface is also exploited in the implementation of the additional photon final state emissions in $τ$ decays using an external {\tt PHOTOS} library rewritten in C.

description: B cells are a type of white blood cell which are responsible for producing antibodies. Antibodies are important in human immunity, as they bind to and neutralize foreign invaders. Blood samples were taken from individual patients to sequence the DNA of their B cells. Previous literature points to a variety of ways to analyze immunoglobulin (antibody) sequencing data, however, we focused on using a high throughput methodology to find antibody clones within an individual’s B cells. We refer to clones as B cells that are derived from the same parent B cell but have undergone small changes (i.e., mutations) resulting in slight differences. This methodology can be customized by focusing on various parameters to identify clones. Our design focused on three specific parameters for an antibody Heavy (H) chain – having (1) the same Variable gene, Joining gene, and junction length, (2) identical Complementarity Determining Region 3 (CDR3) lengths, and (3) 80% similarity in the CDR3 region. In this project, a single individual’s B cell sequencing data was analyzed using R packages to compare these sequences to known germline sequences. An R program was developed to then plot this organized data to create lineage trees, which can help to analyze the path of differentiation a B cell takes and determine mutations occurring within this process. The lineage trees show varying isotypes that were created by the individual’s B cells. This summary data can be aggregated with more individual level sequencing data to better understand the isotype switching route, which is important in understanding human antibody development in autoimmune diseases.
