description: To evaluate the utility of neutrophil–lymphocyte ratio (NLR) determined at initial diagnosis in predicting advanced disease stage and discriminating between active and stable disease in sarcoidosis. A total of 465 patients with biopsy-proven sarcoidosis (age: 47 years, 70.5% females) were included in this retrospective cross-sectional study. Data on patient demographics, sarcoidosis stage, clinical status (stable and active), anti-inflammatory treatments, complete blood count, and inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet/mean platelet volume (MPV) ratio were recorded. NLR values were compared by subgrouping the patients according to the stage of sarcoidosis and clinical status, while the receiver operating characteristics (ROC) curve was plotted to determine the role of NLR in the identification of disease activity with the calculation of area under the curve (AUC) and cutoff value via ROC analysis. Overall, active, and stable disease was evident in 36 (7.8%) and 427 (92.2%) patients, respectively. Median NLR values were significantly higher in patients with active disease compared with stable disease (3.31 (2.34–4.31) vs. 2.29 (1.67–3.23), p = 0.005). Advanced sarcoidosis stage was associated with significantly higher NLR values at stages 0, I, II, III and IV, respectively (p = 0.001). ROC analysis revealed an NLR cutoff value of ≥2.39 (AUC (95% CI): 0.70 (0.62–0.79), p < 0.001) to discriminate between active and stable clinic with a sensitivity of 72.0% and specificity of 52.0%. The significantly higher percentage of patients with active vs. stable disease had NLR values ≥2.39 (74.0 vs. 47.0%, p = 0.002). Our findings indicate the potential utility of on-admission NLR values to predict the risk of advanced disease stage and to discriminate between active and stable disease in sarcoidosis. Measured via a simple, readily available, and low-cost test, NLR seems to be a valuable marker for monitoring disease activity and progression.

description: El propósito de este artículo es describir algunas estructuras lingüísticas, relacionadas con la configuración semántica del texto, utilizadas en dos narraciones escritas por dos alumnos de sexto grado de un colegio púbico de la ciudad de Cartagena. Estas estructuras se contrastan con el documento “Derechos Básicos de Aprendizaje” emitido por el Ministerio de Educación Nacional y se realiza, además, un ejercicio de edición de los textos de los niños; todo este procedimiento se hace con el fin de conocer lo que sabe y no sabe (controla o no) un estudiante al momento de escribir un texto. Los resultados de esta descripción los asociamos y explicamos como señas de inequidad en la educación colombiana. Desde lo teórico, el análisis se basó en la teoría semántica del texto de Teun van Dijk y en la función de los signos de puntuación en la configuración de un texto, propuesta por Carolina Figueras. Se muestran como resultados no solo una explicación de las formas de escribir por parte de algunos niños de colegios públicos de la ciudad, sino también un llamado a que los profesores trabajen en colaboración con ellos, para que se controlen las estructuras discursivas de los textos que se escriben en las aulas y se adquieran recursos simbólicos que propicien la equidad en nuestra sociedad.

description: Words in Sandawe may undergo a grammatically-conditioned tone lowering process in which all tones are realised as low tones. Evidence of the underlying tone pattern can be found in the tone of the final vowel, which is low and level if it is an underlying high tone, and low and falling if it is an underlying low tone. The tone lowering process applies to the head in a genitive construction, an adjective in a NP, some conjunctions and, under certain conditions, to a verb. In several contexts, tone lowering minimally contrasts two different grammatical constructions and therefore carries a high functional load in the language.

description: In Ethiopia, the government has planned to attract many investment projects in manufacturing industry sector to meet the growth plans. Currently, there are 17 new and expansion leather products manufacturing investment projects which are under different phases of investments. Though these projects are initiated to meet the growth and transformation plans portioned for the sector, the lagged performances of these investment projects are contributing to inefficient growth plan of the sector. This study aimed to assess the internal and external challenges during project execution that have contributed to the lagged performances of investment projects. The research design used for this study was descriptive study to focus on the existing internal and external situations that have been negatively affecting the investment projects of leather products industry. A well-structured questionnaire was used to collect data, so that 52 questionnaires were distributed for the census survey of study population of 7 selected projects and 47 surveys were returned from respondents which accounts to 90% response rate. The data have been analyzed using descriptive statistics on SPSS in ways that enable to answer the research questions and achieve the research objectives. Both the internal and external challenges of project execution in Ethiopian leather products manufacturing industry development found to be moderate challenges. Based on the assessment results, the first top three internal challenges of project execution in the leather products manufacturing investment projects are: internal financial resources; practical project execution capability; and people readiness (project staffing). The first top three external challenges of project execution in the leather products manufacturing investment projects are: supply issues; loan issues; and government support issues. By making a comparison between the results of internal and external challenges based on the overall mean and relative importance indexes (RII) that is 3.13 and 0.626 respectively for internal challenges; and 2.71 and 0.542 respectively for external challenges. Therefore, the success of project execution in Ethiopian leather products manufacturing industry development projects have been challenged by external challenges than internal challenges within the project undertaking companies.

description: AGT conjecture connects Nekrasov instanton partition function of 4D quiver gauge theory with 2D Liouville conformal blocks. We re-investigate this connection using the central extension of spherical Hecke algebra in q-coordinate representation, q being the instanton expansion parameter. Based on AFLT basis together with interwiners we construct gauge conformal state and demonstrate its equivalence to the Liouville conformal state, with careful attention to the proper scaling behavior of the state. Using the colliding limit of regular states, we obtain the formal expression of irregular conformal states corresponding to Argyres-Douglas theory, which involves summation of functions over Young diagrams.

Non-zero helicity extinction in light scattered from achiral (or chiral) small particles located at points of null incident helicity density
Creators: name: Nieto-Vesperinas, Manuel
Publisher: name: arXiv
Year: 2016
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Based on a recent unified formulation on dichorism and extinction of helicity on scattering by a small particle, dipolar in the wide sense, magnetodielectric or not, chiral or achiral, we show that such extinction is enhanced not only at resonances of the polarizabilities, but also due to interference between left and right circularly polarized components of the incident wave, which contributes with appropriate parameters of the illuminating field, even if the particle is achiral and is placed at points of the incident field at which the local incident helicity density is zero. This phenomenon goes beyond standard circular dichroism (CD), and we analyze it in detail on account of the values of the several quantities, both of the incident light and the particle, involved in the process. In addition, this interference produces a term in the helicity extinction that remarkably yields information on the real parts of the electric and/or magnetic polarizabilities, which are not provided by CD, of which that helicity extinction phenomenon may be considered a generalization.

El nivel de interpretación y profesionalismo al momento de hacer uso del reglamento fue evaluado con la ayuda de encuestas y entrevistas tras utilizar diferentes recursos educativos digitales durante las explicaciones del formador. 10 árbitros del Colegio A.B.A JJ participaron en el estudio donde se evaluó el nivel inicial y final de interpretación, tras 63 sesiones de enseñanza con la herramienta educativa digital diseñada. Con un 20% la variable en cuestión mejoro significativamente. Sin embargo, se encontró que la interpretación de algunas reglas requiere mejoras, de manera que el nivel de interpretación de los jueces deportivos de Colegio A.B.A JJ precisa “profundizar en algunos aspectos para alcanzar la excelencia”. Las conclusiones del estudio pueden ser resumidas así: “exceptuando las reglas cuyo nivel de interpretación es aceptable, pero con sugerencia de mejora, el nivel de interpretación del Colegio A.B.A JJ luego de aplicar la estrategia pedagógica en el marco de las TIC presentó mejoras significativas y puede ser considerada como Excelente, lo que quiere decir que, el juzgamiento deportivo del Fútbol sala se ve favorecido con el uso de las TIC”

description: Despite the advances in antiretroviral treatment (ART), persistent inflammation remained a challenge. We analyzed the inflammatory-score changes through 2-years in people living with HIV (PLWH) treated with different antiretroviral regimes. This study was conducted in Hacettepe University HIV/AIDS Treatment and Research Center. PLWH diagnosed between 2014 and 2020 were included. Inflammatory and metabolic markers (CD4/CD8 ratio, C-reactive protein (CRP), Systemic Inflammatory Index (SII), Neutrophil-Lymphocyte Ratio (NLR), Mean Platelet Volume (MPV), Platecrite (PCT), and Low-Density Lipoprotein/High-Density Lipoprotein (LDL/HDL), Platelet-to-Lymphocyte Ratio (PLR) and ARTs were captured from database through 2-years from the diagnosis. The 2-year change (Δ) in markers was calculated and compared by ART type (backbone and 3rd agent). Mann-Whitney-U test and T-test were used for statistical analysis. This study included 205 PLWH; 175 (85.4%) were male, and the mean age was 38.98 (±10.88) years. The number of PLWH with suppressed viremia (<40 HIV-RNA copies/ml) was 164 (80%) at the end of the second year. MPV increased significantly higher among PLWH receiving ABC/3TC compared to PLWH receiving TDF/FTC (p < 0.05). The CD4:CD8 ratio increased, and SII, NLR, LDL/HDL ratios decreased significantly among PLWH treated with integrase strand transfer inhibitors (INSTI) compared with protease inhibitors (PI) and Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) (p < 0.05). Integrase inhibitor treatment is related to favorable inflammatory marker profile among PLWH in the 2-year follow-up. A favorable inflammatory profile may, in turn, contribute to the prevention of non-communicable diseases (NCD) among PLWH. This study showed that simple, easy-to-calculate markers could be implemented to define ongoing inflammation among PLWH under suppressive ART.

description: This seminar is more a guided discussion than an ex cathedra presentation on issues that nag me while doing historical linguistics on data from Hunter-Gatherer groups. I take “Hunter-Gatherer” as a very general label for groups that are characterised (rightly or wrongly) as such, and I want to reach a better insight into which distinctions to make among them that are relevant for linguistic study (like immediate and delayed return is for social organisation). After a general introduction the seminar, time is used for one discussion question after the next, all briefly introduced below:
 Q1: Which distinctions to make among Hunter-Gatherer groups in East Africa that have relevance for (socio-)linguistics?
 Q2: Is ethno-linguistic identity less vital for (some of the) Hunter-Gatherer groups?
 Q3: Is there less memory of history of the group among Hunter-Gatherer groups?
 Q4: What are the linguistic properties of Hunter-Gatherer languages?
 Q5: What of this to keep in mind in doing historical linguistics involving languages of Hunter-Gatherer groups?

Year: 2018

description: The study evaluated the adoption and implementation of E-top up service project in ethio telecom. The study was conducted based on the data gathered from six zones in Addis Ababa those are currently providing E-top up service. The total sample size for the study is 110 employees from selected six zones found in Addis. Descriptive research design was employed to conduct this study by using questionnaire. The result of the study indicated that, the major challenges faced in the adoption and development of E-top up services are, Lack of technical and managerial member's awareness with E-top up , lack of technical and managerial skills to implement, lack of legal frame work related to the service, lack of customer awareness, business partners low level of technology adaptation and lack of adequate interaction and cooperation between ethio telecom departments and other decision making centers in the company. The study identified operational and services benefits from adopting and implementation of E-top up such as to enhance foreign currency generation, reduced paper work, reduced transaction cost, increased reliability and reducing errors as operational benefits and overcome geographical limitation, enhance accessibility of the telecom's services (in terms of place), improve customer service, Create better relationship among distributors and Encourages tariff, commission, & incentive transparency as services benefits. The study recommended ethio telecom to facilitate proper and continuous training for their employees, increasing security to gain trust from customers on E-top up usage, create deep awareness about E-top up technology to the community.

The effect of a longitudinal density gradient on electron plasma wake field acceleration

Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: Three dimensional, particle-in-cell, fully electromagnetic simulations of electron plasma wake field acceleration in the blow out regime are presented. Earlier results are extended by (i) studying the effect of longitudinal density gradient; (ii) avoiding use of co-moving simulation box; (iii) inclusion of ion motion; and (iv) studying fully electromagnetic plasma wake fields. It is established that injecting driving and trailing electron bunches into a positive density gradient of ten-fold increasing density over 10 cm long Lithium vapor plasma, results in spatially more compact and three times larger, compared to the uniform density case, electric fields ($-6.4 \times 10^{10}$ V/m), leading to acceleration of the trailing bunch up to 24.4 GeV (starting from initial 20.4 GeV), with an energy transfer efficiencies from leading to trailing bunch of 75 percent. In the uniform density case $-2.5 \times 10^{10}$ V/m wake is created leading to acceleration of the trailing bunch up to 22.4 GeV, with an energy transfer efficiencies of 65 percent. It is also established that injecting the electron bunches into a negative density gradient of ten-fold decreasing density over 10 cm long plasma, results in spatially more spread and two-and-half smaller electric fields ($-1.0 \times 10^{10}$ V/m), leading to a weaker acceleration of the trailing bunch up to 21.4 GeV, with an energy transfer efficiencies of 45 percent. Inclusion of ion motions into consideration shows that in the plasma wake ion number density can increase over few times the background value. It is also shown that transverse electromagnetic fields in plasma wake are of the same order as the longitudinal (electrostatic) ones.

description: It is commonly believed that in the absence of disorder or an external magnetic field, there are three possible types of superconducting excitation gaps: the gap is nodeless, it has point nodes, or it has line nodes. Here, we show that for an even-parity nodal superconducting state which spontaneously breaks time-reversal symmetry, the low-energy excitation spectrum generally does not belong to any of these categories, instead it has extended Bogoliubov Fermi surfaces. These Fermi surfaces can be visualized as two-dimensional surfaces generated by "inflating" point or line nodes into spheroids or tori, respectively. These inflated nodes are topologically protected from being gapped by a $\mathbb{Z}_2$ invariant, which we give in terms of a Pfaffian. We also show that superconducting states possessing these Fermi surfaces can be energetically stable. A crucial ingredient in our theory is that more than one band is involved in the pairing, since all candidate materials for even-parity superconductivity with broken time-reversal symmetry are multiband systems, we expect these $\mathbb{Z}_2$-protected Fermi surfaces to be ubiquitous.

A favorable inflammatory profile may, in turn, contribute to the prevention of non-communicable diseases (NCD) among PLWH. This study showed that simple, easy-to-calculate markers could be implemented to define ongoing inflammation among PLWH under suppressive ART.

description: Der Artikel untersucht die Rolle und den Inhalt von Repräsentationen Westeuropas in innenpolitischen Reformdebatten Russlands zwischen den Revolutionen von 905 und 97. Jene, welche an diesen Debatten teilnahmen, teilten parteiübergreifend eine Reihe von Grundannahmen: Diesen zufolge bewegten sich Russland und Westeuropa auf derselben Entwicklungsleiter vorwärts; Westeuropa verfügte hierbei über einen erheblichen Vorsprung; und Russland war deshalb gut beraten, sich bei seinen weiteren Entwicklungsschritten an jenen Gesetzen und Regelungen zu orientieren, welche der Westen erfolgreich zur Anwendung brachte. Vor dem Hintergrund dieser gemeinsamen Grundannahmen ließ sich mit Repräsentationen Westeuropas Politik machen. Verweise auf den „Westen“ wurden herangezogen, um die unterschiedlichsten Positionen zu begründen und zu legitimieren. Gestritten wurde zwischen den Vertretern verschiedener politischer Ausrichtungen vielfach darüber, wie sich das fortschrittliche „Westeuropa“ im Einzelnen darstelle und wie dessen Erfahrungen zu interpretieren seien. Die Relevanz dieser Diskussionen für genuin innenpolitische Reformen in Russland stellte dagegen so gut wie niemand in Frage.

description: The integration of blockchain technology in financial sectors has emerged as a topic of burgeoning interest, with credit business being a pivotal area of exploration. This study aims to investigate the impact of blockchain technology on the operational efficiency and security of credit business processes. Employing a mixed-methods research design, data was collected from 15 credit institutions that have adopted blockchain technology, alongside a control group of 15 credit institutions operating on traditional digital platforms. Key performance indicators (KPIs) such as transaction speed, error rate, fraud incidence, and operational costs were analyzed. The findings reveal a significant enhancement in operational efficiency and security in credit institutions leveraging blockchain technology. Blockchain adoption was associated with a 70 % reduction in fraudulent activities, a 50 % increase in transaction speed, and a 40 % reduction in operational costs. Furthermore, the decentralized nature of blockchain significantly enhanced transparency and trust among stakeholders, fostering a more robust and resilient credit business ecosystem. The study underscores the transformative potential of blockchain technology in redefining the operational paradigms of credit businesses, thereby contributing to the broader discourse on blockchain’s applicability in financial sectors. Future research is recommended to explore the long-term sustainability and regulatory implications of blockchain integration in credit business operations.
Europe as a Model in International Relations?

description: Der Mauerfall ließ außenpolitische Beratungsinstitute in Deutschland und Frankreich nach neuen Deutungsmustern in den internationalen Beziehungen suchen. Der Artikel vergleicht die Europarepräsentationen in vier Institutionen (Stiftung Wissenschaft und Politik, Deutsche Gesellschaft für Auswärtige Politik, Centre d’études et de recherches internationales, Institut français des relations internationales). In den Arbeiten der Einrichtungen, die von 1990 bis 2000 die arabische Welt behandelten, spielen der Maghreb, die Euro-Mediterrane Partnerschaft und damit zusammenhängende Debatten zentrale Rollen. Wie legitimierten Institutsmitglieder hierbei Europakonzepte? Der Vergleich reicht von gegenseitiger Abhängigkeit bis zum Empire sans empereur mit Mittelmeerachse und zeigt gemeinsame Entwicklungen und nationale Spezifika. In den Debatten machte sich eine zunehmende Konzentration auf die EU bemerkbar; die entscheidungsnahen Beratungseliten behielten ihren engen Bezug zu den nationalen Regierungen. Viele Quellen unterstrichen die Herausforderungen im Mittelmeerraum, andere sprachen der jüngsten europäischen Geschichte Modellcharakter zu – Europa wurde zur Handlungsressource.

description: To evaluate the utility of neutrophil–lymphocyte ratio (NLR) determined at initial diagnosis in predicting advanced disease stage and discriminating between active and stable disease in sarcoidosis. A total of 465 patients with biopsy-proven sarcoidosis (age: 47 years, 70.5% females) were included in this retrospective cross-sectional study. Data on patient demographics, sarcoidosis stage, clinical status (stable and active), anti-inflammatory treatments, complete blood count, and inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet/mean platelet volume (MPV) ratio were recorded. NLR values were compared by subgrouping the patients according to the stage of sarcoidosis and clinical status, while the receiver operating characteristics (ROC) curve was plotted to determine the role of NLR in the identification of disease activity with the calculation of area under the curve (AUC) and cutoff value via ROC analysis. Overall, active, and stable disease was evident in 36 (7.8%) and 427 (92.2%) patients, respectively. Median NLR values were significantly higher in patients with active disease compared with stable disease (3.31 (2.34–4.31) vs. 2.29 (1.67–3.23), p = 0.005). Advanced sarcoidosis stage was associated with significantly higher NLR values at stages 0, I, II, III and IV, respectively (p = 0.001). ROC analysis revealed an NLR cutoff value of ≥2.39 (AUC (95% CI): 0.70 (0.62–0.79), p < 0.001) to discriminate between active and stable clinic with a sensitivity of 72.0% and specificity of 52.0%. The significantly higher percentage of patients with active vs. stable disease had NLR values ≥2.39 (74.0 vs. 47.0%, p = 0.002). Our findings indicate the potential utility of on-admission NLR values to predict the risk of advanced disease stage and to discriminate between active and stable disease in sarcoidosis. Measured via a simple, readily available, and low-cost test, NLR seems to be a valuable marker for monitoring disease activity and progression.
Distinguishing models of surface response through the self-energy of an electron

description: The self-energy of an electron confined between parallel surfaces with arbitrary dielectric properties is calculated. The mechanism for this effect is the surface-induced modification of the fluctuating quantised vacuum field to which the electron is coupled, thereby endowing it with a surface-dependent self-energy in broad analogy to the Casimir-Polder effect for an atom. We derive a general formula for this self-energy shift and find that its sign is different for two commonly-used models of surface response, namely the plasma model and the Drude model. We propose an experiment which could detect this difference in sign, shedding light on continuing uncertainty about the correct description of the interaction of low-frequency vacuum photons with media.

Perspectives for Detecting Lepton Flavour Violation in Left-Right Symmetric Models

description: We investigate lepton flavour violation in a class of minimal left-right symmetric models where the left-right symmetry is broken by triplet scalars. In this context we present a method to consistently calculate the triplet-Yukawa couplings which takes into account the experimental data while simultaneously respecting the underlying symmetries. Analysing various scenarios, we then calculate the full set of tree-level and one-loop contributions to all radiative and three-body flavour-violating fully leptonic decays as well as $μ-e$ conversion in nuclei. Our method illustrates how these processes depend on the underlying parameters of the theory. To that end we observe that, for many choices of the model parameters, there is a strong complementarity between the different observables. For instance, in a large part of the parameter space, lepton flavour violating $τ$-decays have a large enough branching ratio to be measured in upcoming experiments. Our results further show that experiments coming online in the immediate future, like Mu3e and BELLE II, or longer-term, such as PRISM/PRIME, will probe significant portions of the currently allowed parameter space.

“Fortress Europe” or “Europe as Empire“ –

Publisher: name: Leipziger Universitätsverlag

description: Der Artikel vergleicht zwei Repräsentationen der Europäischen Gemeinschaft, die “Festung Europa“ und „Europa als Imperium“ miteinander und untersucht sie als Fremdzuschreibungen hin auf ihre Kompatibilität mit der gemeinsamen europäischen Außenpolitik in den 990er Jahren. Im Mittelpunkt stehen dabei die Euromediterrane Partnerschaft und die EU-Erweiterung 2004. Er geht davon aus, dass diese Fremdzuschreibungen auch deshalb solche Popularität erlangten, da sie zwar zugespitzt die beiden extremen Pole europäischer Außenpolitik beschreiben, aber von „Innen“, aus der Perspektive Brüssels, nicht in Übereinstimmung mit den Eigenrepräsentationen der Gemeinschaft gebracht werden können und daher weniger Analysen europäischer Politik denn Kritik an Europa sind. Sie spiegeln so vielmehr die Dilemmata wider, vor denen die Politiker nach dem Fall des „Eisernen Vorhangs“ standen und auf die die EG aufgrund ihrer Eigenrepräsentationen und Sprachregelungen in nur eingeschränkter Weise reagieren konnte.

description: Globally, ancient DNA has been a disruptive force in studies of the human past, triggering debates on research ethics, methods, interpretations, and stakeholder engagement. Although ancient DNA was long thought inaccessible in the tropics, whole genomes have now been sequenced from the remains of more than 100 people buried at African archaeological sites spanning the last 20,000 years, sometimes providing insights not available from other lines of evidence. This talk will consider how recent archaeogenetic findings compare to archaeological records, focusing principally on the Rift Valley of Tanzania and Kenya, and will invite a discussion of how linguists and archaeologists might work together closely as the field of ancient DNA matures, inviting greater interdisciplinary dialogue and more equal-footed collaborations.
description: Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change. Acknowledgement and citation: Prendergast, Mary. 2022. Ancient DNA and the African Past. Talk Given at Rift Valley Webinar Series 06/04/2022.

description: This paper draws attention to a hardware system which can be engineered so that its intrinsic physics is described by the generalized Ising model and can encode the solution to many important NP-hard problems as its ground state. The basic constituents are stochastic nanomagnets which switch randomly between the $\pm 1$ Ising states and can be monitored continuously with standard electronics. Their mutual interactions can be short or long range, and their strengths can be reconfigured as needed to solve specific problems and to anneal the system at room temperature. The natural laws of statistical mechanics guide the network of stochastic nanomagnets at GHz speeds through the collective states with an emphasis on the low energy states that represent optimal solutions. As proof-of-concept, we present simulation results for standard NP-complete examples including a 16-city traveling salesman problem using experimentally benchmarked models for spin-transfer torque driven stochastic nanomagnets.
