Floral morphology of blueberry (Vaccinium ashei Reade) and stigma pollen deposition

<p><span>We measured five floral traits in each flower, on 50 flowers for each cultivar (Bluebelle, Bluegem, Britteblue, Climax, Powderblue, Woodard, Florida, and Delite) of blueberry (<em>Vaccinium ashei</em> Reade). In total, 750 flowers in four locations in the Rio Grande do Sul State, in Brazil, were analyzed. To assess the impact of floral morphology on pollination, we counted the number of pollen grains on the stigma of flowers after 24 hours of free visitation. The dataset was used to verified whether floral morphology differs between eight blueberry cultivars and, if this variation influences pollination, to infer the role of floral morphology in the interaction with floral visitors.</span></p&gt

A Scalable, Biopolymer-Based Microenvironment for Electrochemical CO2 Conversion to Multicarbon Products with Current Densities Over 2 A/cm2

<p>The electrochemical CO<sub>2</sub> reduction reaction (CO<sub>2</sub>RR) offers a sustainable approach for converting CO<sub>2</sub> into valuable fuels and chemicals. CO<sub>2</sub>RR relies on copper (Cu) catalysts to produce desirable multicarbon (C<sub>2+</sub>) products, but C<sub>2+</sub> yields rely heavily on the surrounding microenvironment. Moreover, controlling the microenvironment to achieve high C<sub>2+</sub> yields at industrially-relevant current densities remains a persistent challenge. To address this challenge, we show that biopolymer coatings on the Cu electrodes can tune the microenvironment, enabling a new strategy to achieve high yields of C<sub>2+</sub> products at ultra-high current densities. This approach achieves remarkable C<sub>2+</sub> Faradaic efficiencies (FE<sub>C2+</sub>) of 90±1.7% at 1.6 A cm<sup>-2</sup> and FE<sub>C2+</sub>=83±3.2% at 2.2 A cm<sup>-2</sup> with a formation rate of 5925.9 μmol h<sup>−1 </sup>cm<sup>−2</sup>. Furthermore, these biopolymers can even fully substitute traditional ionomers and binders, such as Nafion, within the cathode. Our findings challenge previous assumptions about the non-viability of hydrophilic materials for CO<sub>2</sub>RR and provide critical new insights into microenvironment design to enhance C-C coupling. Several complementary investigations reveal that biopolymer coatings increase local CO<sub>2</sub>/CO concentration, lower local water activity, and provide suitable ion conductivity and local pH. We anticipate that these molecular-level insights represent a paradigm shift in catalyst design to unlock new approaches to optimize the microenvironment for CO<sub>2</sub>RR to enable high rates of C-C coupling without the typical unwanted increase in hydrogen evolution. These abundant biopolymer coatings are environmentally benign, solution-processable, and highly accessible, which is expected to provide researchers with a facile route towards high-performance CO<sub>2</sub>RR at both laboratory and industrial scales.</p&gt

Dataset of "Comparison of Localization Methods for Internet of Things in 5G Cellular Networks: A Wide-scale Assessment"

<p>As the 3rd generation partnership project (3GPP) organization pushes out new releases,<br>positioning in heterogeneous mobile networks enables the achievement of the accuracy required<br>in the majority of industrial applications without dependence on global navigation<br>satellite systems (GNSS). This study presents the results gathered during an extensive measurement<br>campaign related to the practical applicability of localization in next-generation<br>heterogeneous networks. We present an accuracy comparison of basic timing advance (TA)<br>localization with the k-nearest neighbor (KNN), decision tree-based random forest (RF),<br>extreme gradient boosting (XGBoost), and long short-term memory (LSTM) recurrent neural<br>network. Our results demonstrate that TA cannot be considered an optimal solution<br>from the perspective of localization accuracy because the error roughly corresponds to the<br>average separation distance from the base station (BS) to the end device (ED). In addition,<br>we found that the LSTM approach is not optimal for the outdoor localization of moving<br>ED because of the combination of multiple factors, with sparse deployment being the most<br>important. The median value of the location error of the LSTM was more than 200m higher<br>than that of the TA for the self-validation dataset. However, a simple KNN regression shows<br>solid results for 5G New Radio (NR) operating in the non-standalone (NSA) mode. KNN<br>provided the most accurate results of all methods, with median error values of approximately<br>12 (k=3) and 82 (k=5) m for the self-validated and cross-validated datasets, respectively.</p&gt

Multivalent Antigen Display on Nanoparticles Diversifies B Cell Responses

Nanoparticles for multivalent display and delivery of vaccine antigens have emerged as a promising avenue for enhancing B cell responses to protein subunit vaccines. Here, we evaluated B cell responses in rhesus macaques immunized with prefusion stabilized Respiratory Syncytial Virus (RSV) F glycoprotein trimer compared to nanoparticles displaying 10 or 20 copies of the same antigen. We show that multivalent display skews antibody specificities and drives epitope-focusing of responding B cells. Antibody cloning and repertoire sequencing revealed that focusing was driven by expansion of clonally distinct B cells through recruitment of diverse precursors. We identified two antibody lineages that developed either ultrapotent neutralization or pneumovirus cross-neutralization from precursor B cells with low initial affinity for the RSV-F immunogen. This suggests that increased avidity by multivalent display facilitates the activation and recruitment of these cells. Diversification of the B cell response by multivalent nanoparticle immunogens has broad implications for vaccine design

"Consultation horoscopique, divination, jeu, oracles ludiques ? Autour de la Tabula Bianchini", in V. Dasen, Th. Daniaux (éds), Locus Ludi. Quoi de neuf sur la culture ludique antique ? Pallas 119, 2022, p. 491-509

The “Tabula Bianchini”, discovered on Mount Aventine in Rome and now kept in the Louvre Museum, is one of the tools that astrologers used to establish horoscopes. In 1931 Wilhelm Gundel proposed a ludic hypothesis regarding the use of the “Tabula”. We will revisit his commentary, relating it to other ludic objects that may have had astrological use, including graffiti consisting of an eight-part circle and a rock crystal icosahedron. The analysis will make it possible to underline the existing links between the sphere of play, astrology and divination, so frequent in ancient literature
