Temperature-dependent molecular absorption cross sections for exoplanets and other atmospheres

Exoplanets, and in particular hot ones such as hot Jupiters, require a very significant quantities of molecular spectroscopic data to model radiative transport in their atmospheres or to interpret their spectra. This data is commonly provided in the form of very extensive transition line lists. The size of these line lists is such that constructing a single model may require the consideration of several billion lines. We present a procedure to simplify this process based on the use of cross sections. Line lists for water, H$_3^+$, HCN /HNC and ammonia have been turned into cross sections on a fine enough grid to preserve their spectroscopic features. Cross sections are provided at a fixed range of temperatures and an interpolation procedure which can be used to generate cross sections at arbitrary temperatures is described. A web-based interface (www.exomol.com/xsec) has been developed to allow astronomers to download cross sections at specified temperatures and spectral resolution. Specific examples are presented for the key water molecule.Comment: Icarus (submitted

Extracting B→K∗B \to K^* Form Factors from Data

We extract ratios of $B \to K^*$ form factors at low hadronic recoil from recent data on $B \to K^* \mu^+ \mu^-$ decays in a model-independent way. The presented method will improve in the future with further (angular) studies in semileptonic rare B-decays and advance our understanding of form factors, which are important inputs in precision tests of the Standard Model

Optofluidic Force Induction as a Process Analytical Technology

Manufacturers of nanoparticle-based products rely on detailed information about critical process parameters, such as particle size and size distributions, concentration, and material composition, which directly reflect the quality of the final product. These process parameters are often obtained using offline characterization techniques that cannot provide the temporal resolution to detect dynamic changes in particle ensembles during a production process. To overcome this deficiency, we have recently introduced Optofluidic Force Induction (OF2i) for optical real-time counting with single particle sensitivity and high throughput. In this paper, we apply OF2i to highly polydisperse and multi modal particle systems, where we also monitor evolutionary processes over large time scales. For oil-in-water emulsions we detect in real time the transition between high-pressure homogenization states. For silicon carbide nanoparticles, we exploit the dynamic OF2i measurement capabilities to introduce a novel process feedback parameter based on the dissociation of particle agglomerates. Our results demonstrate that OF2i provides a versatile workbench for process feedback in a wide range of applications.Comment: 10 pages, 5 figure

Referencing Sources of Molecular Spectroscopic Data in the Era of Data Science: Application to the HITRAN and AMBDAS Databases

The application described has been designed to create bibliographic entries in large databases with diverse sources automatically, which reduces both the frequency of mistakes and the workload for the administrators. This new system uniquely identifies each reference from its digital object identifier (DOI) and retrieves the corresponding bibliographic information from any of several online services, including the SAO/NASA Astrophysics Data Systems (ADS) and CrossRef APIs. Once parsed into a relational database, the software is able to produce bibliographies in any of several formats, including HTML and BibTeX, for use on websites or printed articles. The application is provided free-of-charge for general use by any scientific database. The power of this application is demonstrated when used to populate reference data for the HITRAN and AMBDAS databases as test cases. HITRAN contains data that is provided by researchers and collaborators throughout the spectroscopic community. These contributors are accredited for their contributions through the bibliography produced alongside the data returned by an online search in HITRAN. Prior to the work presented here, HITRAN and AMBDAS created these bibliographies manually, which is a tedious, time-consuming and error-prone process. The complete code for the new referencing system can be found at \url{https://github.com/hitranonline/refs}.Comment: 11 pages, 5 figures, already published online at https://doi.org/10.3390/atoms802001

Teaching in the garden: school gardens as a space for environmental and English learning

School gardens as settings for learning outside the classroom are becoming increasingly popular. They allow students to learn in an authentic way as they engage in a variety of activities and materials. More importantly, they also represent a powerful place and tool for environmental education as students are not only exposed to nature but also gain positive environmental experiences. This paper examines school gardens as a place for both enhancing students’ English language competences and fostering critical environmental literacy. The first section of the paper focuses on garden-based education as a type of learning outside the classroom. The ensuing section then provides a brief discussion of school gardens as learning spaces across the curriculum, arguing that school gardens are far more than places for learning about nutrition and healthy living. Following this, the next section then argues for using school gardens also for learning English as a foreign language. Here Gardner’s multiple intelligences model serves to illustrate the potential of school gardens for differentiated instruction regarding content, processes, and products in today’s increasingly diverse learning groups. The main part of the paper then concentrates on garden-based education in the context of EFL teacher training. At the University of Education Karlsruhe (Germany) students have the opportunity to attend a school garden-based seminar which allows them to experience first hand the benefits of learning English as a foreign language in the school garden. The paper concludes by taking a glimpse into the future of school garden learning by reporting on the authors’ experiences with using technology in the context of garden-based education.Los huertos escolares como escenario para el aprendizaje fuera del aula son cada vez más populares. Permiten que los estudiantes aprendan de una manera auténtica mientras participan en actividades que implican una variedad de actividades y materiales. De forma más relevante, estos también representan un lugar y una herramienta poderosa para la educación ambiental, ya que los estudiantes no sólo están expuestos a la naturaleza, sino que también recogen experiencias en la naturaleza, lo que les permite obtener experiencias ambientales positivas. En este documento se examinan los huertos escolares como un lugar para mejorar las competencias de los estudiantes en el idioma inglés y fomentar una alfabetización ambiental crítica. La primera sección del documento se centra en la educación basada en los jardines como un tipo de aprendizaje fuera del aula. A continuación, se ofrece un breve análisis de los huertos escolares como espacios de aprendizaje en todo el programa de estudios, argumentando que los huertos escolares son mucho más que lugares para aprender sobre nutrición y vida saludable. A continuación, en la siguiente sección se argumenta que los huertos escolares también sirven para aprender inglés como lengua extranjera. Aquí el modelo de inteligencias múltiples de Gardner sirve para ilustrar el potencial de los huertos escolares para la instrucción diferenciada en cuanto a contenido, procesos y productos en los grupos de aprendizaje cada vez más diversos de hoy en día. La parte principal del trabajo se centra entonces en la educación basada en los huertos en el contexto de la formación de profesores de EFL. En la Universidad de Educación de Karlsruhe (Alemania), los estudiantes tienen la oportunidad de asistir a un seminario sobre huertos escolares que les permite experimentar de primera mano las ventajas de aprender inglés como lengua extranjera en este espacio. La contribución concluye echando un vistazo al futuro del aprendizaje en los huertos escolares, informando sobre las experiencias de los autores en el uso de la tecnología en el contexto de la educación basada en los huertos

The homological slice spectral sequence in motivic and Real bordism

For a motivic spectrum $E\in \mathcal{SH}(k)$, let $\Gamma(E)$ denote the global sections spectrum, where $E$ is viewed as a sheaf of spectra on $\mathrm{Sm}_k$. Voevodsky's slice filtration determines a spectral sequence converging to the homotopy groups of $\Gamma(E)$. In this paper, we introduce a spectral sequence converging instead to the mod 2 homology of $\Gamma(E)$ and study the case $E=BPGL\langle m\rangle$ for $k=\mathbb R$ in detail. We show that this spectral sequence contains the $\mathcal{A}_*$-comodule algebra $(\mathcal{A}//\mathcal{A}(m))^*$ as permanent cycles, and we determine a family of differentials interpolating between $(\mathcal{A}//\mathcal{A}(0))^*$ and $(\mathcal{A}//\mathcal{A}(m))^*$. Using this, we compute the spectral sequence completely for $m\le 3$. In the height 2 case, the Betti realization of $BPGL\langle 2\rangle$ is the $C_2$-spectrum $BP_{\mathbb R}\langle 2\rangle$, a form of which was shown by Hill and Meier to be an equivariant model for $\mathrm{tmf}_1(3)$. Our spectral sequence therefore gives a computation of the comodule algebra $H_*\mathrm{tmf}_0(3)$. As a consequence, we deduce a new ($2$-local) Wood-type splitting $$\mathrm{tmf}\wedge X\simeq \mathrm{tmf}_0(3)$$ of $\mathrm{tmf}$-modules predicted by Davis and Mahowald, for $X$ a certain 10-cell complex.Comment: Comments welcom
