Conventional Measurements of Sulfur Dioxide (SO2) in Red Wine Overestimate SO2 Antimicrobial Activity

Conventional approaches to measuring sulfur dioxide (SO2) in wine, such as aeration-oxidation, iodometric titration, and flow-injection analysis, are known to overestimate molecular SO2, particularly in red wine because of the dissolution of weak anthocyanin-bisulfite complexes during analysis. Methods for determining molecular SO2 without perturbing anthocyanin-bisulfite complexes and other weak adducts exist, e.g., headspace gas-detection tube measurements. However, it is unclear whether SO2 values achieved through conventional methods (“Molecular SO2”) or nonperturbing methods (molecular SO2) provide a better measure of antimicrobial activity. In our work, white and pseudo-red wines were prepared with varying additions of SO2; the red wine was produced by spiking the white wine with an anthocyanin extract. “Molecular SO2” and molecular SO2 concentration in white wines were well correlated, but “Molecular SO2” was significantly higher in red wines. Wines were inoculated with Saccharomyces cerevisiae strain EC1118 (Lallemand), and viability and culturability were evaluated at regular intervals. Both culturable and viable cell counts decreased significantly for treatments with 0.5 to 2.0 mg/L molecular SO2 in the white and red wines, and for 0.5 to 2.0 mg/L “Molecular SO2” in the white wine, but concentrations >2.0 mg/L “Molecular SO2” were necessary to decrease cell counts in the red wine. These results indicate that anthocyanin-bisulfite complexes have negligible antimicrobial activity, and that conventional approaches to measuring “Molecular SO2” are poorly suited to predicting the microbial stability of red wines.

Fossil History of Curculionoidea (Coleoptera) from the Paleogene

Currently, some 564 species of Curculionoidea from nine families (Nemonychidae—4, Anthribidae—33, Ithyceridae—3, Belidae—9, Rhynchitidae—41, Attelabidae—3, Brentidae—47, Curculionidae—384, Platypodidae—2, Scolytidae—37) are known from the Paleogene. Twenty-seven species are found in the Paleocene, 442 in the Eocene and 94 in the Oligocene. The greatest diversity of Curculionoidea is described from the Eocene of Europe and North America. The richest faunas are known from Eocene localities, Florissant (177 species), Baltic amber (124 species) and Green River formation (75 species). The family Curculionidae dominates in all Paleogene localities. Weevil species associated with herbaceous vegetation are present in most localities since the middle Paleocene. A list of Curculionoidea species and their distribution by location is presented.
How users' knowledge of advertisements influences their viewing and selection behavior in search engines

According to recent studies, search engine users have little knowledge of Google's business model. In addition, users cannot sufficiently distinguish organic results from advertisements, resulting in result selections under false assumptions. Following on from that, this study examines how users' understanding of search‐based advertising influences their viewing and selection behavior on desktop computer and smartphone. To investigate this, we used a mixed methods approach (n = 100) consisting of a pre‐study interview, an eye‐tracking experiment, and a post‐study questionnaire. We show that participants with a low level of knowledge on search advertising are more likely to click on ads than subjects with a high level of knowledge. Moreover, subjects with little knowledge show less willingness to scroll down to organic results. Regarding the device, there are significant differences in viewing behavior. These can be attributed to the influence of the direct visibility of search results on both devices tested: Ads that were ranked on top received significantly more visual attention on the small screen than the top ranked ads on the large screen. The results call for a clearer labeling of advertisements and for the promotion of users' information literacy. Future studies should investigate the motivations of searchers when clicking on ads.
Difference without distinction? Gaps in cyanobacterial systematics; when more is just too much

Cyanobacteria are amongst the most abundant, ubiquitous, ecologically and evolutionarily significant microbes on Earth. Unique among the Bacteria in their capacity to be identified using morphology, understanding the evolutionary relationships and describing the diversity of this lineage is both important and challenging. The advent of modern sequencing technology has proven a boon to those studying cyanobacterial systematics as it has provided copious amounts of sequence data (mainly of the 16S rRNA gene sequence). However, this influx of data has also led to taxonomic confusion and recognition of polyphyly in many genera. Thus, the purpose of this paper is to describe this apparent paradox of increasing data yet poor phylogenetic resolutions by employing the Poisson Tree Process (PTP) algorithm and to propose some ameliorative efforts.
Response of Eragrostis plana and Eragrostis pilosa (L.) P. Beauv. submitted on flooded soil

The development of Eragrostis plana and Eragrostis pilosa was evaluated in a greenhouse when submitted to different soil moisture conditions. The design was completely randomized, consisting of a factorial 2x3, with the following factors: Eragrostis accessions and soil moisture levels (50% of water retention capacity (WRC), 100% of WRC and soil with water depth of 10 cm). The morphological-anatomical parameters of the plants were evaluated and the aerenchyma and adventitious roots were quantified. In addition, the photosynthetic pigments and the electron transport capacity of the photosynthetic chain were quantified, with the intention of verifying if the amount of water in the soil interferes with these parameters. Similar responses were observed between the two species when submitted to a water table environment, where there were larger aerenchymal formations in the roots and stems, as well as adventitious roots at the soil surface, inferring adaptations for survival to anaerobic stress. Negative effects on the transport of electrons and the formation of chlorophyll pigments were observed for both species when submitted to the hypoxic environment and, consequently, there was reduction of dry mass of shoot and roots, as well as reduction in the emission of tiller. It is concluded that the irrigation water management and the water blade in the rice crop are important, together with the control of invasive plants, considering the negative effects caused to the growth and development of these plants
Communication in Genomics and Proteomics Cloning proenkephalin from the brain of a urodele amphibian (Taricha granulosa) using a DOR-speciWc primer in a 3RACE reaction

A large cDNA fragment that codes for proenkephalin (PENK) was cloned from the rough-skinned newt, Taricha granulosa (GenBank Accession: AY817670). This 1299-bp PENK cDNA extends from the poly(A) sequence on the 3 end into the 5-UTR (221 bp) upstream of an open reading frame that codes for 264 amino acids and a stop codon. Within the precursor are Wve Met-enkephalin sequences and two C-terminally extended forms of Met-enkephalin (YGGFMRGV and YGGFMRY). The organization of the opioid core sequences within the newt PENK closely resembles that reported for other vertebrates. In this urodele amphibian, as in anurans, PENK does not contain the penultimate Leu-enkephalin opioid sequence found in mammals, and instead has in this position Met-enkephalin. PENK cDNA was ampliWed from newt brain in a RACE PCR targeting the 3 end of the newt delta opioid receptor (DOR). It remains to be determined whether generating the cDNA for the newt PENK while cloning its receptor was serendipitous or the result of a meaningful coincidence between the DOR and PENK sequences.
Longitudinal relationship between trait gratitude and subjective well-being in adolescents: Evidence from the bi-factor model

ABSTRACT Previous studies have rarely explored the predictive causality relationship between trait gratitude and subjective well-being (SWB) that has been demonstrated to have a bi-factor structure (i.e., three specific factors and a general factor of SWB). A sample of 494 adolescents participated in a two-wave study including the measurements of trait gratitude and SWB. We employed structural equation modeling techniques to assess cross-lagged effects between trait gratitude and the bi-factor structure of SWB (i.e., life satisfaction, negative affect, positive affect and the general SWB factor) in four models. The results showed that trait gratitude could predict life satisfaction and positive affect, but could not predict negative affect and the general SWB factor over two months. Besides, there was no evidence for the reverse or reciprocal relationships between trait gratitude and the bi-factor structure of SWB. Implications and future directions of the findings were discussed.
Automatic radio map creation in a fingerprinting‐based BLE/UWB localisation system

: One of the most popular localisation algorithms used in radio localisation systems is fingerprinting. The method has significant advantages: its implementation is easy and since it does not require any information on system infrastructure placement, it can be implemented in already deployed networks. However, it has a significant drawback, which is a high effort needed to create the radio map used for localisation. This study describes a low-effort method for automatic radio map creation intended for use in hybrid Bluetooth low energy/ultra-wideband (BLE/UWB) positioning systems. The proposed method adopts fingerprint crowdsourcing and radio map interpolation approaches. It consists in collecting signatures comprising user location calculated using an UWB subsystem and measured BLE signal levels. The recorded data is used to identify parameters of a log-distance path loss model and a Gaussian process regressor and interpolate a complete radio map. The presented concept was experimentally tested. The results have shown that the method allows for more accurate localisation than conventional received signal strength ranging based solution.
Selection of Important Bryophyte Areas in Hungary

Until now 99 sites could be selected as important bryophyte areas on the basis of 125 populations of 26 European red-listed species and an additional three species protected by law in Hungary. Most of the species with confirmed recent occurrences have few existing populations. The most important habitats from the point of view of the conservation of European red-listed bryophytes are places with shaded rocks or rocks in streams in forest-covered mountainous areas, which maintain 30% of the existing Hungarian populations of European red-listed species. Saline-alkali and dry rocky grasslands and loess cliffs are also very important habitats in the preservation of submediterranean, continental, and subcontinental elements. Wet grasslands nowadays are of minor importance in the preservation of rarities as they are in very bad conditions mainly due to dry climatic periods of the last decades. Similarly, the number of populations of species living on decaying wood and tree bark is not high either.
Power Scaling and Antenna Selection Techniques for Hybrid Beamforming in mmWave Massive MIMO Systems

With the advent of massive MIMO and mmWave, Antenna selection is the new frontier in hybrid beamforming employed in 5G base stations. Tele-operators are reworking on the components while upgrading to 5G where the antenna is a last-mile device. The burden on the physical layer not only demands smart and adaptive antennas but also an intelligent antenna selection mechanism to reduce power consumption and improve system capacity while degrading the hardware cost and complexity. This work focuses on reducing the power consumption and finding the optimal number of RF chains for a given millimeter wave massive MIMO system. At first, we investigate the power scaling method for both perfect Channel State Information (CSI) and imperfect CSI where the power is reduced by 1/number of antennas and 1/square root (number of antennas) respectively. We further propose to reduce the power consumption by emphasizing on the subdued resolution of Analog-to-Digital Converters (ADCs) with quantization awareness. The proposed algorithm selects the optimal number of antenna elements based on the resolution of ADCs without compromising on the quality of reception. The performance of the proposed algorithm shows significant improvement when compared with conventional and random antenna selection methods.

 distributed model predictive control of nonlinear processes

This work addresses the design of distributed model predictive control (DMPC) systems for nonlinear processes using machine learning models to predict nonlinear dynamic behavior. Specifically, sequential and iterative distributed model predictive control systems are designed and analyzed with respect to closed-loop stability and performance properties. Extensive open- loop data within a desired operating region are used to develop Long Short-Term Memory (LSTM) recurrent neural network models with a sufficiently small modeling error from the actual nonlinear process model. Subsequently, these LSTM models are utilized in Lyapunov- based DMPC to achieve efficient real-time computation time while ensuring closed-loop state boundedness and convergence to the origin. Using a nonlinear chemical process network exam- ple, the simulation results demonstrate the improved computational efficiency when the process is operated under sequential and iterative DMPCs while the closed-loop performance is very close to the one of a centralized MPC system.
Fake Pearls Made from Tridacna gigas Shells

The Journal of Gemmology, 35(5), 2017, pp. 424–429, http://dx.doi. org/10.15506/JoG.2017. 35.5. 424 © 2017 The Gemmological Association of Great Britain Five non-nacreous ‘pearls’ that allegedly came from Tridacna gigas (giant clams) were studied for this report. Our observations revealed that none of them were pearls, but instead they had been manufactured from Tridacna clam shell. The identiication of such imitations is in most cases straightforward, and is mainly based on their characteristic layered structure observed in relected light and with transmitted ibre-optic illumination. Our results are compared with recent reports of other such fake pearls that are often wrongly described as being genuine natural pearls. Fake Pearls Made from Tridacna gigas Shells
Radiofrequency ablation of benign thyroid nodules: recommendations from the Asian Conference on Tumor Ablation Task Force

Radiofrequency ablation (RFA) is a thermal ablation technique widely used for the management of benign thyroid nodules. To date, five academic societies in various countries have reported clinical practice guidelines, opinion statements, or recommendations regarding the use of thyroid RFA. However, despite some similarities, there are also differences among the guidelines, and a consensus is required regarding safe and effective treatment in Asian countries. Therefore, a task force was organized by the guideline committee of the Asian Conference on Tumor Ablation with the goal of devising recommendations for the clinical use of thyroid RFA. The recommendations in this article are based on a comprehensive analysis of the current literature and the consensus opinion of the task force members.
Transcriptional Regulation in Cancer-Driven Cellular Stress and Functional Specialization of a Myosin Heavy Chain Protein, MYH7B

Cancer is a disease of dysregulated gene expression in which many developmental programs are hijacked. One such program is the cellular response to hypoxia, or low oxygen stress. Hypoxia-inducible factors (HIF) govern the cell’s response to this stressor. While much is known about the transcriptional programs HIF directs, comparably little is known about the transcriptional regulation enabling the progression of this response. In the first two chapters of this thesis, I report on the current state of knowledge of the HIF transcriptional program and present new evidence for the role of the conserved coactivator, TIP60, on HIF1A, the primary driver of the cellular response to hypoxia and potent oncogene. Sarcomeric myosin heavy chain proteins are mechanochemical enzymes that provide the mechanical force required for muscle contraction. These proteins belong to a long-studied and well-described family with numerous implications in heart and skeletal muscle diseases. In the final chapter of my thesis, I present evidence for the exclusion of a myosin heavy chain protein, MYH7B, from mammalian cardiac tissue as a beneficial evolutionary adaptation despite its abundant expression in mammal’s evolutionary neighbor, reptiles.
Nigerian healthcare workers’ perception of transdisciplinary approach to older adults’ care: A qualitative case study

Introduction There is a growing interest in collaborative care for older adults in Nigeria; however, little is known about the application of a transdisciplinary approach to care in a typical Nigerian geriatric unit. Therefore, we described healthcare professionals’ (HCPs’) perception of a transdisciplinary approach to older adults’ care in Southern Nigeria. Methods Using Stakian’s approach to a qualitative case study, we purposively invited 16 HCPs working in the geriatric unit of a teaching hospital in Nigeria to a single, in-depth, semi-structured interview. We analysed data using Stakian’s approach of categorical aggregation and direct interpretation. Results Our participants identified five-key features of a transdisciplinary approach to care: consolidated consultation, consolidated care documentation, care files accessibility, shared care decision and a designated care manager. HCPs stated that transdisciplinary approach to care allowed for a consolidated consultation of patients, with all the HCPs (in the same room or via telehealth/telemedicine) and care decisions should be shared between all stakeholders and documented in an accessible unified electronic care document that is managed by a care manager. Factors ranging from lack of consensus on time for a consolidation consultation to inter-professional conflicts were perceived as possible hindrances to a transdisciplinary approach to older adults’ care. Discussion The features of transdisciplinary care described in this study partly aligned with the WHO’s integrated care for older people (ICOPE). Additional components not captured in ICOPE were found. While the description of transdisciplinary was from the perceptive of our study participant, caution should be applied when interpreting these findings.
Piezoaeroelastic system on the basis of a double aerodynamic pendulum

During last decades, possibilities to use piezoelectric generators to harvest energy from the flow‐induced vibrations of different structures are intensively studied. In particular, various wind power harvesters based on fluttering oscillations of wing sections are proposed. In this work, an electromechanical system is considered that consists of a double aerodynamic pendulum connected with a piezoelectric element in such a way that rotation of the first link of the pendulum results in deformation of the piezoelement. The element is connected to a load resistance. Stability of the trivial equilibrium is analyzed, and conditions for stability loss are discussed. It is shown, in particular, that it is possible to choose parameters of the system in such a way that the trivial equilibrium (where both links of the pendulum are oriented along the incoming flow) is unstable when the wind speed belongs to a certain finite range of values, and asymptotically stable outside this range. Periodic solutions of the system are studied numerically depending on the wind speed and the moment of inertia of the second pendulum link. The effect of disappearance of limit cycles in the range of large wind speeds is demonstrated.
