description: The motion of a block slipping on a surface is a well studied problem for flat and circular surfaces, but the necessary conditions for the block to leave (or not) the surface deserve a detailed treatment. In this article, using basic differential geometry, we generalize this problem to an arbitrary surface, including the effects of friction, providing a general expression to determine under which conditions the particle leaves the surface. An explicit integral form for the velocity is given, which is analytically integrable for some cases, and we find general criteria to determine the critical velocity at which the particle immediately leaves the surface. Five curves, a circle, ellipse, parabola, catenary and cycloid, are analyzed in detail. Several interesting features appear, for instance, in the absense of friction, a particle moving on a catenary leaves the surface just before touching the floor, and in the case of the parabola, the particle never leaves the surface, regardless of the friction. A phase diagram that separates the conditions that lead to a particle stopping in the surface to those that lead to a particle departuring from the surface is also discussed.

description: Elevated serum calcium levels may serve as a useful clinical biomarker of mortality in patients with multiple myeloma(MM). However, the clinical significance of the relationship between serum calcium levels and in-hospital mortality in MM patients admitted to the Intensive Care Unit (ICU) remains unclear. This study aimed to explore the association between serum calcium levels and in-hospital mortality in patients with MM in the ICU. Patients with MM were identified from the Medical Information Mart for Intensive Care IV(MIMIC-IV) database. The outcome was in-hospital mortality. Multivariable-adjusted Cox regression analysis, curve fitting, and threshold effects analysis were used to assess the relationship between serum calcium levels and in-hospital mortality in patients with MM in the ICU. Our study included 262 patients with MM with a mean age of 72.3 ± 11.0 years, 63.4% of whom were male. The in-hospital mortality was 19.5% (51/262). The relationship between serum calcium levels and in-hospital mortality was nonlinear. The effect size on the left and right sides of the inflection point, were 0.270 (HR: 0.270, 95% CI 0.106-0.687, P < 0.05) and 2.104 (HR: 2.104, 95% CI 1.069-4.142, P < 0.05), respectively. The results of the sensitivity analysis remained stable. Our findings show that a nonlinear relationship exists between serum calcium levels and in-hospital mortality in critically ill patients with MM. A serum calcium level of approximately 8.40 mg/dL was associated with the lowest risk of in-hospital mortality, which increases with rising serum calcium levels, and should be of concern to ICU physicians.

description: Chemotherapy, including bendamustine, usually causes lymphocytopaenia and hypogammaglobulinaemia as side effects in patients with haematological malignancies. Therefore, the possibility has been considered that these immunological adverse events induced by bendamustine may lead to infectious diseases. However, lymphocytopaenia and/or hypogammaglobulinaemia have not yet been shown to have a statistically significant association with infection in cancer patients who receive bendamustine. We retrospectively studied 27 patients with relapsed or refractory indolent follicular lymphoma who were treated with bendamustine and rituximab (BR). In order to elucidate relationships between immune-related laboratory parameters (i.e. peripheral blood leukocyte, neutrophil, lymphocyte and immunoglobulin G [IgG]) and infectious events, receiver operating characteristic (ROC) curve and multivariate logistic regression analyses were performed. Infectious diseases occurred in 11 patients (11/27, 41%), including 3 (3/27, 11%) with severe diseases. The area under the ROC curve (AUC) showed that the lowest IgG level during and after BR discriminated infectious events (cut-off value, 603 mg/dL) with 81.8% sensitivity and 68.8% specificity (AUC, 0.76; 95% CI, 0.52-0.90). Furthermore, a multivariate regression analysis revealed that the minimal serum IgG value during and after BR therapy was the only variable that was significantly associated with infection (odds ratio, 8.29; 95% CI, 1.19-57.62; p value, 0.03). Serum IgG ≤603 mg/dL during and after BR therapy was independently associated with an increased risk of infection. The monitoring of serum IgG during chemotherapy may help to predict the development of infection in blood cancer patients undergoing chemotherapy with bendamustine in combination with rituximab.

description: Pyrochlore oxides possessing "all-in-all-out" spin ordering have attracted burgeoning interest as a rich ground of emergent states. This ordering has two distinct types of magnetic domains (all-in-all-out or all-out-all-in) with broken time-reversal symmetry, and a non-trivial metallic surface state has been theoretically demonstrated to appear at their domain wall. Here, we report on observation of this metallic conduction at the single all-in-all-out/all-out-all-in magnetic domain wall formed at the heterointerface of two pyrochlore iridates. By utilizing different magnetoresponses of them with different lanthanide ions, the domain wall is controllably inserted at the heterointerface, the surface state being detected as anomalous conduction enhancement with a ferroic hysteresis. Our establishment paves the way for further investigation and manipulation of this new type of surface transport.

description: Patients with haematologic malignancies are at high risk of developing invasive fungal infections (IFIs). Current guidelines recommend the use of azoles for IFI prophylaxis; however, in many clinical situations, antifungal prophylaxis is used off-label. We conducted a systematic literature review to provide haematologists with the available evidence on the effectiveness and safety of isavuconazole in IFI prophylaxis in interventional and real-world, observational studies. Embase, MEDLINE and Cochrane Library databases, and relevant conference proceedings and clinical trial registries, were searched for studies on the effectiveness and safety of isavuconazole prophylaxis in adults at high risk of IFIs. Studies were assessed for inclusion and risk of bias. Nine studies were eligible for inclusion in the review, eight of which were in haematologic populations (patients undergoing haematopoietic stem cell transplantation or with acute myeloid leukaemia or myelodysplastic syndromes; n = 5) or included haematologic populations (n = 3). Evidence from these studies suggests isavuconazole is effective for IFI prophylaxis in the haematologic setting. However, the studies frequently lacked safety data, most were based on small patient populations from single centres and risk of bias could not be assessed for five studies. These findings provide evidence for isavuconazole as an alternative azole for prophylaxis in high-risk populations. Limitations include lack of applicability of risk of bias assessment tools, level of filtering applied in the search strategy and focus on English-language publications. Isavuconazole may be an effective azole for IFI prophylaxis in high-risk haematologic populations, although further studies are needed.

description: Graham et al. found a sample of active galactic nuclei (AGNs) and quasars from the Catalina Real-time Transient Survey (CRTS) that have long-term periodic variations in optical continuum, the nature of the periodicity remains uncertain. We investigate the periodic variability characteristics of the sample by testing the relations of the observed variability periods with AGN optical luminosity, black hole mass and accretion rates, and find no significant correlations. We also test the observed periods in several different aspects related to accretion disks surrounding single black holes, such as the Keplerian rotational periods of 5100~Å photon-emission regions and self-gravity dominated regions and the precessing period of warped disks. These tests shed new lights on understanding AGN variability in general. Under the assumption that the periodic behavior is associated with SMBHB systems in particular, we compare the separations ($\mathscr{D}_{\bullet}$) against characteristic radii of broad-line regions ($R_{\rm BLR}$) of the binaries and find $\mathscr{D}_{\bullet}$$\approx$ 0.05 $R_{\rm BLR}$. This interestingly implies that these binaries have only circumbinary BLRs.

description: Cybersecurity professionals need hands-on training to prepare for managing the current advanced cyber threats. To practice cybersecurity skills, training participants use numerous software tools in computer-supported interactive learning environments to perform offensive or defensive actions. The interaction involves typing commands, communicating over the network, and engaging with the training environment. The training artifacts (data resulting from this interaction) can be highly beneficial in educational research. For example, in cybersecurity education, they provide insights into the trainees' learning processes and support effective learning interventions. However, this research area is not yet well-understood. Therefore, this paper surveys publications that enhance cybersecurity education by leveraging trainee-generated data from interactive learning environments. We identified and examined 3021 papers, ultimately selecting 35 articles for a detailed review. First, we investigated which data are employed in which areas of cybersecurity training, how, and why. Second, we examined the applications and impact of research in this area, and third, we explored the community of researchers. Our contribution is a systematic literature review of relevant papers and their categorization according to the collected data, analysis methods, and application contexts. These results provide researchers, developers, and educators with an original perspective on this emerging topic. To motivate further research, we identify trends and gaps, propose ideas for future work, and present practical recommendations. Overall, this paper provides in-depth insight into the recently growing research on collecting and analyzing data from hands-on training in security contexts.

description: This paper studies a prototype of inverse initial boundary value problems whose governing equation is the heat equation in three dimensions. An unknown discontinuity embedded in a three-dimensional heat conductive body is considered. A {\it single} set of the temperature and heat flux on the lateral boundary for a fixed observation time is given as an observation datum. It is shown that this datum yields the minimum length of broken paths that start at a given point outside the body, go to a point on the boundary of the unknown discontinuity and return to a point on the boundary of the body under some conditions on the input heat flux, the unknown discontinuity and the body. This is new information obtained by using enclosure method.

description: Entangled qudits, the high-dimensional entangled states, play an important role in the study of quantum information. How to prepare entangled qudits in an efficient and easy-to-operate manner is still a challenge in quantum technology. Here, we demonstrate a method to engineer frequency entangled qudits in a spontaneous parametric downconversion process. The proposal employs an angle-dependent phase-matching condition in a nonlinear crystal, which forms a classical-quantum mapping between the spatial (pump) and spectral (biphotons) degrees of freedom. In particular, the pump profile is separated into several bins in the spatial domain, and thus shapes the down-converted biphotons into discrete frequency modes in the joint spectral space. Our approach provides a feasible and efficient method to prepare a high-dimensional frequency entangled state. As an experimental demonstration, we generate a three-dimensional entangled state by using a homemade variable slit mask.

description: Obstructive sleep apnea (OSA) is reported to be a cause of secondary polycythemia. The present study (i) reviewed the literature reporting the prevalence of secondary polycythemia in patients with OSA and (ii) determined the effect of continuous positive airway pressure (CPAP) therapy on hemoglobin and hematocrit levels in patients with OSA. We searched MEDLINE, Embase and Cochrane for studies of adult patients with OSA that reported hemoglobin and/or hematocrit levels. We performed summary estimates of (i) polycythemia prevalence and a subgroup analysis according to OSA severity, and (ii) change in hemoglobin and hematocrit levels following treatment with CPAP. Synthesis of seven studies including 3,654 patients revealed an overall polycythemia prevalence of 2% (95% CI 1–4%); 2% (95% CI 1–3%) in mild-to moderate and 6 % (95% CI 3–12%) in severe OSA. In the pooled analysis of ten single-arm trials including 434 patients, CPAP treatment reduced hemoglobin by 3.76 g/L (95% CI −4.73 to −2.80 g/L). Similarly, pooled analysis of ten single-arm trials including 356 patients without baseline polycythemia showed that CPAP treatment reduced hematocrit by 1.1% (95% CI −1.4 to −0.9%). Our pooled analysis supports an increased prevalence of secondary polycythemia in OSA. This estimated prevalence is likely underestimated due to the change in the polycythemia diagnostic criteria in 2016. Future randomized controlled trials are needed to evaluate the effect of CPAP in patients with baseline polycythemia. Pooled analysis shows OSA is associated with an increased prevalence of secondary polycythemiaPrevalence of polycythemia is greater in severe OSACPAP treatment for OSA reduces both the hemoglobin and hematocrit Pooled analysis shows OSA is associated with an increased prevalence of secondary polycythemia Prevalence of polycythemia is greater in severe OSA CPAP treatment for OSA reduces both the hemoglobin and hematocrit

description: Die modernen Wirtschaftswissenschaften sind weithin stark mathematisiert, formalisiert und durch die Verwendung abstrakter Konzepte geprägt. In der Konsequenz müssen Studierende der Wirtschaftswissenschaft mit abstrakten Konzepten umgehen können, die nötigen Formalismen beherrschen sowie die Sprache der Mathematik verstehen. In der Praxis jedoch, so zeigen reichhaltige Erfahrungen in der Lehre, überwiegen bei diesen vielmehr Abneigung bis Angst gegenüber Formalismen und Abstraktion – mit negativen Konsequenzen für den Studienerfolg. Daher besteht das Ziel des Projektes „Abstraktionstraining“ darin, die Einstellung der Studierenden zur Abstraktion positiv zu beeinflussen sowie die Bereitschaft und Fähigkeit zur passiven wie aktiven Abstraktion zu fördern. Das Projekt wird im Umfeld der Kurse zur „Mathematik für Wirtschaftswissenschaftler“ an der Universität Paderborn angesiedelt.

description: In der Mathematik für Wirtschaftswissenschaftler spielt der Ableitungsbegriff eine zentrale Rolle, z.B. beim Konzept der Grenzkosten. Das Verständnis des Konzepts in den Wirtschaftswissenschaften unterscheidet sich jedoch vom Verständnis der Ableitung in der Mathematik. In diesem Beitrag wird am Beispiel der Grenzkosten als wesentliche Anwendung der Ableitung in den Wirtschaftswissenschaften analysiert, worin dieser Unterschied besteht und wie in ausgewählten verbreiteten wirtschaftswissenschaftlichen Fachbüchern mit dem Grenzkostenkonzept umgegangen wird. Weiterhin wird darstellt, was Studierende am Ende eines Kurses „Mathematik für Wirtschaftswissenschaftler“ für eine verständige Anwendung der Ableitung beim Grenzkostenkonzept wissen sollten. Außerdem wird anhand von Ergebnissen eines Vortests dargestellt, welches Vorwissen die Studienanfänger im Hinblick auf intendierte Wissen mitbringen.

description: 1. La inadecuada atención a la crisis humanitaria que vive el país. La primera conclusión que se tiene en cuenta en este trabajo de investigación es la certeza de que Colombia atraviesa por una crisis humanitaria producto de la ola de violencia generalizada de los últimos veinte años, esta crisis no ha sido afrontada de una forma adecuada por el Estado Colombiano teniendo en cuenta que ha estado muy flojo en la implementación de políticas públicas coherentes y realizables que tiendan a reparar de manera integral a todas las víctimas de violaciones a los derechos humanos. Esta investigación concluye que el trabajo de construcción de políticas públicas tendientes a afrontar la crisis humanitaria en Colombia se ha realizado por un lado de forma tardía, y por otro sin los criterios necesarios para atender la situación de tal forma que las víctimas no se encuentren ante una revictimizaciónpor el mismo Estado. Sin embargo el último año se ha mostrado cierta voluntad por parte del presidente Juan Manuel Santos de saldar según palabras del mismo presidente de la republica la deuda histórica que tiene el Estado con las víctimas de crímenes atroces; en este sentido lo primero que hace el presidente es reconocer que en Colombia aún existe el Conflicto y que se encuentra latente en las regiones, prueba de ello es el despojo y abandono forzado de tierras en todo el territorio nacional y especialmente en la región de los Montes de María tema y región en donde esta investigación hace especial énfasis. Existen en Colombia varias leyes expedidas con el objetivo de afrontar la crisis humanitaria, desde el año de 1997, se expide la ley 387 de 1997 como el primer instrumento que reconoce el problema del desplazamiento forzado masivo, pero esta ley se quedó corta con respecto al problema humanitario de forma integral, se concentró en la atención al desplazamiento forzado y le restó importancia al tema del despojo y abandono forzado, a pesar de que la ley es expedida en 1997 solo hasta 2003 se incluyen en los formularios del registro único de Población desplazada RUPD preguntas sobre patrimonios abandonados, lo que prueba que esta fuente tiene un gran vacío sobre el tema de 1998 a 2003. La Ley 975 de 2005 conocida como de Justicia y Paz, tiene un alcance amplio dirigido a facilitar la desmovilización de grupos armados, reconoce también los derechos a la verdad, la justicia y la reparación de las víctimas de dichos grupos armados, pero hasta hoy solo se cuenta en el país con solo una sentencia expedida en virtud de la misma y ningún caso de violaciones a los derechos humanos reparado de forma integral.

description: Purpose Our aim is to analyze the clinical characteristics and prognostic factors of Epstein-Barr (EB) virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) in children. Methods Children with newly diagnosed HLH were retrospectively analyzed. Results Finally, a total of 95 children with HLH were enrolled in this study, including 43 (45.3%) with EBV-HLH and 52 (54.7%) with non-EBV-HLH. Laboratory tests showed that the levels of absolute neutrophil count (ANC) decrease (P = 0.031) and triglycerides (TG) increase (P = 0.036) in the EBV-HLH group were statistically significant compared with those in the non-EBV-HLH group, respectively. We found that the remission rate during induction period in the EBV-HLH group and non-EBV-HLH group was 75.8% and 89.3%, respectively. The correlation analysis showed that the elevated degree of total bilirubin (TBIL) (P = 0.042), triglyceride (TG) (P = 0.009), serum ferritin (SF) (P = 0.008) and interleukin-8 (IL-8) (P = 0.004) were related with the remission rate during induction in the EBV-HLH group. Further univariate analysis showed that the elevated degree of TBIL (P = 0.048) and TG (P = 0.019) were significant risk factors for the remission rate during induction in the EBV-HLH group. In the multivariate analysis, we observed that there was statistical significance for the degree of TG elevation (P = 0.015) between the two groups. The correlation analysis showed that the elevated degree of TBIL (P = 0.030), the elevated degree of SF (P = 0.020) and the elevated degree of interleukin-6 (P = 0.010) were related to the induction mortality of children with EBV-HLH. Conclusion TBIL and TG are valid indicators to assess the efficacy and prognosis of EVBHLH among children in induction period.
Wetting theory for small droplets on textured solid surfaces

description: Conventional wetting theories on rough surfaces with Wenzel, Cassie-Baxter, and Penetrate modes suggest the possibility of tuning the contact angle by adjusting the surface texture. Despite decades of intensive study, there are still many experimental results that are not well understood because conventional wetting theory, which assume an infinite droplet size, has been used to explain measurements of finite-sized droplets. In this study, we suggest a wetting theory that is applicable to any droplet size based on the free energy landscape analysis of various wetting modes of finite-sized droplets on a 2D textured surface. The key finding of our study is that there are many quantized wetting angles with local free energy minima; the implication of this is remarkable. We find that the conventional theories can predict the contact angle at the global free energy minimum if the droplet size is 40 times or larger than the characteristic scale of the surface roughness. Furthermore, we confirm that the pinning origin is the local free energy minima and obtain the energy barriers of pinning as a function of geometric factors. We validate our theory against experimental results on an anisotropic rough surface. In addition, we discuss wetting on a non-uniform rough surface with a rough central region and flat edge. Our findings clarify the extent to which the conventional wetting theory is valid and expand the physical understanding of wetting phenomena of small liquid drops on rough surfaces.

Cotunneling into a Kondo lattice with odd hybridization

subject: FOS: Physical sciences

description: Cotunneling into Kondo systems, where an electron enters a $f$-electron material via a cotunneling process through the local-moment orbital, has been proposed to explain the characteristic lineshapes observed in scanning-tunneling-spectroscopy (STS) experiments. Here we extend the theory of electron cotunneling to Kondo-lattice systems where the bulk hybridization between conduction and $f$ electrons is odd under inversion, being particularly relevant to Kondo insulators. Compared to the case of even hybridization, we show that the interference between normal tunneling and cotunneling processes is fundamentally altered: it is entirely absent for layered, i.e., quasi-two-dimensional materials, while its energy dependence is strongly modified for three-dimensional materials. We discuss implications for STS experiments.
