Determining sugar and molasses origin by non-exchangeable hydrogen stable isotope of ethanol and carbon isotope ratio mass spectrometry
<p>This study explores the differentiation of sugar and molasses produced from sugar beet and cane, which are susceptible to fraudulent labeling due to differing production costs. The research aimed to authenticate these products by botanical origin using novel analytical techniques. Utilizing ethanol isotopic measurement–isotope ratio mass spectrometry (IRMS) for non-exchangeable hydrogen stable isotopes alongside carbon stable isotopes analysis through elemental analyzer–IRMS, the study accurately identified the origin of various sugar and molasses samples, pinpointed mislabeled goods, and determined the source of products with previously unknown provenance. These methods were also effective in revealing sugar and molasses adulteration and quantifying the extent of such fraud. The combined isotope analyses demonstrated their potential as robust tools for combating misrepresentation and adulteration in the sugar industry.</p>

Stable isotope ratios data of NEREA Augmented Observatory
<p>Samples were collected at 1m depth or along the whole water column using Niskin bottles and plankton nets, transferred into bins or jars and transported to the laboratory, where the individual size fractions were isolated. For each size fraction, samples were frozen and freeze-dried individually. Carbon and nitrogen stable isotope values (‰) were determined at the Stable Isotope Facility at the University of california in Davis (USA).</p>
How stable are solar-type cycles over half a century? Chromospheric S-indices Mt. Wilson vs. TIGRE
<p> <br>by Klaus-Peter Schröder (1); Jürgen Schmitt (2); Marco Mittag (2)<br>Departamento de Astronomia, Universidad de Guanajuato, Mexico; Hamburger<br>Sternwarte, University of Hamburg, Germany</p> <p>Since autumn 2013, the robotic 1.2m telescope TIGRE (formerly the Hamburg Robotic<br>Telescope) is operating in Guanajuato (Mexico, and see poster by Gonzalez et al.). Regularly<br>using the same calibration stars for S-indices as did the Mount Wilson project (see Baliunas et<br>al. 1995), our R=20,000 HEROS echelle spectra have provided a decade of chromospheric<br>activity monitoring of the same ca. 100 solar-type stars, including a smaller number with<br>pronounced cycles (see Schröder et al. 2013) of periods of o(10yrs), which were already<br>observed at Mount Wilson since the 1970ies. Hence, on a timescale of half a century, we can<br>now use those same stars, first shown by Olin C. Wilson and his group to perform solar-type<br>activity cycles, to probe the stability of these cycles. This is motivated by the solar cycle<br>variability, which is evident, when comparing the last two, relatively weak maxima monitored by<br>TIGRE, with the Mount Wilson data from the 1970ies and 1980ies. Hence, we here show that<br>this is not a singular behavior. Strong cycles seem to be less variable, while weaker cycles like<br>the solar are natural to change between stronger and weaker performance. In the case of the<br>Sun this behavior is consistent with an o(century)-period as of the semi-regular Gleissberg<br>cycle, as well as with the occurrence of grand-minima.</p> <p><br>Theme(s): The Sun and Cool Stars in the Time Domain, Cool Stars as Stellar Systems</p>

Interaction of planarly stable trivial and non-trivial travelling waves in a three-species competition-diffusion system
<p>We consider the situation where an exotic species <em>w</em> invades an ecosystem inhabited by two native species <em>u</em> and <em>v</em>. All species are competing for the same limited resource. Supposing that <em>u</em> and <em>v</em> are not able to coexist in the absence of the invader, we want to determine whether a successful invasion by <em>w</em> may allow all species to coexist (competitor-mediated coexistence). Mathematically, this problem can be modelled by the following three-species competition-diffusion system<br> <span class="math-tex">\( \left\{ \begin{alignedat}{6} u_t &= d_1 \, \Delta u &&+ (r_1 &&- u &&- b_{12} \, v &&- b_{13} \, w &&)\,u, \\ v_t &= d_2 \, \Delta v &&+ (r_2 &&- v &&- b_{21} \, u &&- b_{23} \, w &&)\,v, \\ w_t &= d_3 \, \Delta w &&+ (r_3 &&- w &&- b_{31} \, u &&- b_{32} \, v &&)\,w, \end{alignedat} \right.\)</span><br> where all parameters are positive constants.</p> <p>We are interested in the case in which the invading species is weaker than the native ones, i.e., it is not able to survive in the diffusion-free system obtained by setting <em>d</em><sub>1</sub> = <em>d</em><sub>2</sub> = <em>d</em><sub>3</sub> = 0.<br> We fix all parameters as<br> <span class="math-tex">\( \begin{aligned} & d_1 = d_2 = d_3 = 1, \\ & r_1 = r_2 = 28, \\ & \begin{aligned} b_{12} &= 22/21, & b_{13} &= 4, \\ b_{21} &= 1.87, & b_{23} &= 3/4, \\ b_{31} &= 26/21, & b_{32} &= 22/21, \\ \end{aligned} \end{aligned}\)</span><br> and leave <em>r</em><sub>3</sub>, which measures the strength of the exotic species, as a free parameter. Depending on the value of <em>r</em><sub>3</sub>, the invasion can be either successful or not and competitor-mediated coexistence may or may not occur.</p> <p>It turns out that if <em>r</em><sub>3</sub> lies in a certain range of values, the three-species competition-diffusion system admits two planarly stable travelling wave solutions. In the movies here presented, the result of the interaction of these two waves in two spatial dimensions is reported for several value of <em>r</em><sub>3</sub>. The species <em>u</em>, <em>v</em> and <em>w</em> are denoted by the red, green and blue colours respectively. The yellow line marks the interface between the species <em>u</em> and <em>v</em>. As the value of the free parameter decreases, we observe a transition from a regular spiral pattern, to a breathing spiral and finally to a complex spatio-temporal pattern born from the break-up of the spiral. This complex pattern may be either periodic or chaotic in the long run, as can be seen in the movies for longer time intervals <em>T</em>.</p>
