New bioactive secondary metabolites from dung beetle-associated bacteria

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Insect-microbial symbioses are increasingly recognized as ubiquitous phenomena in insect ecology, possibly driving co-evolution [1]. Secondary metabolites produced by insect-associated bacteria could play important roles by mediating symbioses. Structural novelty and biological activity of symbiotic bacterial metabolites notably encouraged to study these tremendous chemical sources for biomedical purpose [2]. In our investigation, we isolated an identical bacterial strain, belonging to the genus Streptomyces, from the dung beetle Copris tripartitus inhabiting Jeju Island three times between 2012 and 2014. This bacterial strain SNU607 produced two oxindole naphtalenediones which were previously unreported. The planar structures of the compounds were determined by UV, MS spectral data and 1D/2D NMR spectroscopic techniques, while the absolute configurations of the compounds were determined by ECD. These two novel compounds, coprisidins A and B (1 and 2), were presumably produced through an unusual biosynthesis pathway. Coprisidins A and B inhibit the action of Na+/K+ ATPase (IC50 of 1 = 8.95 µg/mL) and of Staphylococcus aureus sortase A (IC50 of 2 = 32.9 µg/mL). We also isolated three more putatively associated bacterial strains from the dung beetle's gut (SNU471, SNU502, and SNU533 [3]) producing new peptide class compounds. Here we report the dung beetle-associated bacterial isolation, the structural elucidation of their secondary metabolites, and the biological activities of the compounds.
On being yourself in different cultures: ideal and actual self-concept, autonomy support, and well-being in China, Russia, and the United States

Field: Psychology (Social Sciences)

The present study used multilevel modeling and measures of the Big Five to test Rogers’ prediction that discrepancies between ideal and actual self-concept would be negatively associated with well-being, and to test the prediction drawn from self-determination theory that partners’ autonomy support would be associated with smaller discrepancies. Discrepancies and well-being were found to be negatively associated in samples from the USA, Russia, and China, but participants’ actual self-concept was closer to their ideal when with autonomy supportive partners. Although there was some moderation by country membership, associations were in the same direction for all countries. Discussion focuses on the cultural and clinical implications.
Semisynthesis of Rosmanol and Its Derivatives. Easy Access to Abietatriene Diterpenes Isolated from the Genus Salvia with Biological Activities

Field: Chemistry (Physical Sciences)

The known diterpenes rosmanol (3), rosmaquinone (4), 7-methoxyrosmanol (5), 7-ethoxyrosmanol (6), galdosol (7), and epirosmanol (8) have been obtained by partial synthesis from carnosol (2), an abundant natural product present in Salvia species. The physical and spectroscopic data of these semisynthetic diterpenes were identical to those of authentic natural samples and with data reported in the literature. These abietane diterpenes have very interesting biological activities and are present in the genus Salviain low quantities; thus, the semisynthetic approach described here represents an efficient alternative method to obtain these compounds. Additionally, the known diterpene 16-hydroxyrosmanol (10) and a new aromatic diterpene 11 were obtained from 16-hydroxycarnosol (9) by reaction with Ph3P/NBS in CH2Cl2. The structure of the new compound 11 was established from its spectroscopic data as 12,16-epoxycarnosol.
Aeroelastic analysis of a helicopter rotor in hover

Field: Engineering (Physical Sciences)

The paper deals with the numerical analysis of a helicopter rotor in hover conditions, including aeroelastic effects. In existing literature the effects of an aircraft structural deformation on airloads distribution and performance are fairly well described but mainly for airplanes. The purpose of the presented work is to indicate the possible influence of blades elasticity on helicopter rotor loads and performance in hover. Additionally, it aims to validate a new computational method based on a set of experimental results for a UH-60A helicopter rotor. The method used combines a high fidelity Navier-Stokes aerodynamic model coupled with a low-order beam structural model. This approach made it possible to take into consideration blade deformations in simulations and revealed the high influence of aeroelastic effects on rotor loads and performance at hover conditions. To authenticate the results, the presented method was validated with experimental data from two different flight test programs, three small-scale wind tunnel tests and one full-scale wind tunnel test. They were conducted for the UH-60A helicopter rotor by different organizations. The comparison of results revealed that the created computational method has high accuracy.

SH0751809.10FU

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
Cloning and Expression of Calmodulin Genes Regulating Phytoalexin Production in Carrot Cells

Field: Agricultural and Biological Sciences (Life Sciences)

A homology-based cloning strategy yielded four cDNA clones encoding the open reading frame of carrot calmodulin, designated cam-4 and cam-8 from an oligogalacturonide elicitor-treated cell culture and cam-11 and cam-16 from cells exposed to ethylene, respectively. Reverse-transcription polymerase chain reaction analyses revealed that the expression of the cam-4 gene increased transiently when carrot seedlings were treated with oligogalacturonides, although, the cells incubated with fungal mycelial walls or ethylene did not show a significant change in the expression level. In contrast, marked and transient expression was observed for either cam-11 or cam-16 only when carrot cells were treated with ethylene. These results suggest that two classes of stimuli which are capable of triggering phytoalexin production in carrot cells, oligogalacturonides and ethylene, evoke the activation of the Ca2+ cascade in the cells by expressing distinct calmodulin genes to initiate the biosynthesis of the compound.
ICDAR 2005 Arabic handwriting recognition competition

Field: Computer Science (Physical Sciences)

This paper describes the Arabic handwriting recognition competition for ICDAR 2005. With the presentation of the IFN/ENIT-database in the year 2002 a database with handwritten Arabic town names was made available for free to non commercial research groups. Till now more than 30 groups are working with this data worldwide. By announcing a competition of Arabic handwriting recognition systems based on the IFN/ENIT-database, we hope to contribute to the development of Arabic handwriting recognition systems. The use of the same database by different research groups allows the comparison of different systems. We compare the systems on the most important characteristic: recognition rate, but also features like word length, writing style, and character connectivity will be discussed.
How Nitrogen Doping Affects Hydrogen Spillover on Carbon-Supported Pd Nanoparticles: New Insights from DFT

Field: Chemistry (Physical Sciences)

The process of hydrogen spillover on metal nanoparticle decorated carbon surfaces has been discussed for many years due to its importance for heterogeneous catalysis and hydrogen storage. The present density functional theory (DFT) study supports recent experimental observations of the hydrogen spillover process. By use of model systems of carbon-supported palladium nanoparticles, the details of hydrogen spillover are investigated and the effects of nitrogen doping on such processes are elucidated. It is found that graphitic nitrogen atoms and water molecules significantly facilitate the hydrogen spillover reaction and serve as anchoring sites for the spillover hydrogen atoms.
Secure multi-party computation problems and their applications

Field: Computer Science (Physical Sciences)

The growth of the Internet has triggered tremendous opportunities for cooperative computation, where people are jointly conducting computation tasks based on the private inputs they each supplies. These computations could occur between mutually untrusted parties, or even between competitors. For example, customers might send to a remote database queries that contain private information; two competing financial organizations might jointly invest in a project that must satisfy both organizations' private and valuable constraints, and so on. Today, to conduct such computations, one entity must usually know the inputs from all the participants; however if nobody can be trusted enough to know all the inputs, privacy will become a primary concern.This problem is referred to as Secure Multi-party Computation Problem (SMC) in the literature. Research in the SMC area has been focusing on only a limited set of specific SMC problems, while privacy concerned cooperative computations call for SMC studies in a variety of computation domains. Before we can study the problems, we need to identify and define the specific SMC problems for those computation domains. We have developed a framework to facilitate this problem-discovery task. Based on our framework, we have identified and defined a number of new SMC problems for a spectrum of computation domains. Those problems include privacy-preserving database query, privacy-preserving scientific computations, privacy-preserving intrusion detection, privacy-preserving statistical analysis, privacy-preserving geometric computations, and privacy-preserving data mining.The goal of this paper is not only to present our results, but also to serve as a guideline so other people can identify useful SMC problems in their own computation domains.
Gemcitabine plus oxaliplatin in advanced hepatocellular carcinoma (AHCC): results of a phase II study

Field: Medicine (Health Sciences)

4086 Background: New therapies are needed to improve the prognosis of patients (pts) with AHCC. The rationale to develop the gemcitabine / oxaliplatin combination in AHCC is based on: (i) the synergy between these two drugs, (ii) the clinical activity of these drugs in HCC according to preliminary phase II results, (iii) the lack of renal or hepatic toxicity of oxaliplatin in cirrhotic pts. Recently, we conducted a pilot study to evaluate two distinct bimonthly schedules of gemcitabine plus oxaliplatin in advanced HCC. We have therefore selected the most promising schedule to perform a phase II trial in non pre-treated AHCC patients. Methods: 30 pts with non pre-treated AHCC were prospectively enrolled. They received gemcitabine 1000 mg/m2 d1 and oxaliplatin 100 mg/m2 d2 (GEMOX). Treatment was repeated every two weeks until disease progression or limiting toxicity. Eligibility criteria were: pathologically proven advanced HCC or alpha-fetoprotein (AFP) levels over 250 ng/ml associated with a radiological liver tumor, PS (ECOG) 0–2, age ≥ 18, measurable disease, adequate hematological and renal functions, compensated Child A or B cirrhosis, and written informed consent. Results: Twenty six patients are currently evaluable for toxicity and efficacy. Their characteristics, treatment toxicity and clinical activity are summarized in the following table. No Toxic death occurred. Hematological grade 3–4 toxicities consisted in thrombocytopenia (18%), anemia (18%) and neutropenia (30%), without any febrile neutropenia or bleeding event. No grade3–4 non hematological toxicity was observed. Grade 1 and 2 neurotoxicity (specific scale) was observed in 14 and 6 pts, respectively. Four objective responses were observed, one leading to a surgical resection of the tumor. Conclusions: gemcitabine plus oxaliplatin seems to be an active regimen with manageable toxicity in non pre-treated AHCC patients. No significant financial relationships to disclose.
Watermarking methods

Field: Computer Science (Physical Sciences)

Watermarks. The term evokes visions of shady characters secretly beavering away in dark basements surrounded by forged $100 bills drying on clothes lines. In a digital media context, away from the traditional world of inks and paper, the same old problem remains but it relates not just to forgery but also to outright theft, because one digital copy can spawn millions of others with the single click of a mouse button. It is hardly surprising that the notion of a digital watermark has stimulated avid interest amongst artists and publishers alike. It is commonly recognized that digital watermarks must be as robust as the media in which they are embedded. For example, a rotated, cropped, and rescanned water-marked image should still be a watermarked image. However, this robustness requirement directly conflicts with the need for a digital watermark to be unobtrusive. The most effective techniques used to embed watermarks are the result of a combination of secret key-based techniques used for military communication and simple models of the human visual system. The most familiar application for digital watermarks is for copyright protection and protection of intellectual property. On its own, a watermark does not provide any legal proof of ownership. In other words, the use of a given digital watermark to protect intellectual property must be registered with a trusted third party to be of any value. Any technique for embedding robust digital watermarks must be compatible with methods for registering copyright. A watermark's resistance to intentional and unintentional degradation has been the main subject of interest in the watermarking community. The main challenges are geometric transformations such as change of proportion or simple rescaling. One watermark removal technique that is supplied on the Internet simply shifts a corner of the image. Lossy image compression such as JPEG and filtering are more easily overcome and, generally speaking, watermarks have evolved into very resistant forms. The laboratory, but will they really work in the real world?

Physiological potential of irrigated rice seeds treated with amino acids and under salt stress

Field: Agricultural and Biological Sciences (Life Sciences)

Salt stress in rice plants affects growth, development and crop yield. However, seed treatment can reduce the deleterious effects caused by salt stress. The use of amino acids in agriculture has increased, both in Brazil and in other countries, due to higher productivity and provide better quality of plants treated with amino acids. The objective of this study was to evaluate the effect of amino acid coating on the physiological potential of rice seeds under salt stress. The experimental design was a completely randomized three-way factorial design with two batches of seeds, two levels of amino acid treatment (with or without amino acid) and five salt concentrations (0.0, 25.0, 50.0, 75.0 and 100.0 mM) with four replicates. The physiological quality of seeds was assessed by a germination test, first germination count, cold test, accelerated aging, seedling shoot and root lengths, and dry weight of shoots and roots. It is concluded that the seed treatment with amino acids results in better physiological performance of rice seeds when subjected to salt stress, which affects negatively the physiological quality of seeds.
Three-Dimensional Numerical Simulation and Performance Study of an Industrial Helical Static Mixer

Field: Chemical Engineering (Physical Sciences)

Abstract In many branches of processing industries, viscous liquids need to be homogenized in continuous operations. Consequently, fluid mixing plays a critical role in the success or failure of these processes. Static mixers have been utilized over a wide range of applications such as continuous mixing, blending, heat and mass transfer processes, chemical reactions, etc. This paper describes how static mixing processes of single-phase viscous liquids can be simulated numerically, presents the flow pattern through a helical static mixer, and provides useful information that can be extracted from the simulation results. The three-dimensional finite volume computational fluid dynamics code used here solves the Navier-Stokes equations for both laminar and turbulent flow cases. The turbulent flow cases were solved using k-ω model and Reynolds stress model (RSM). The flow properties are calculated and the static mixer performance for different Reynolds numbers (from creeping flows to turbulent flows) is studied. A new parameter is introduced to measure the degree of mixing quantitatively. Furthermore, the results obtained by k-ω and RSM turbulence models and various numerical details of each model are compared. The calculated pressure drop is in good agreement with existing experimental data.
A role for rare soil bacteria in ecosystem functions

Field: Environmental Science (Physical Sciences)

The microbial life in soil is highly diverse with an estimated species number of 104-106 species per gram soil of which the majority is supposed to be rare. In spite of their low abundance they have been found to support important biogeochemical processes, such as denitrification, and contribute to the stability of ecosystem functions under changing environmental conditions. Moreover a study by Hol et al. (2010) has shown that rare soil bacteria can influence plant performance and suggests that they might prime plant defenses against herbivore attack. In my research I address the hypotheses that rare soil microbes provide distinct and vulnerable ecological functions, insure ecosystem processes under environmental changes and disturbances and potentially affect plant performance and herbivore resistance. For this purpose I will first attempt the cultivation of low abundant soil bacteria and their identification by combined high-throughput- and Sanger-sequencing to subsequently test isolates for their ability to degrade specific substrates. On the long term isolated strains will also be investigated for their effect on plant performance and induction of plant resistance to herbivore and pathogen attack. Changes in abundance will be monitored to assess their contribution to ecosystem stability under environmental changes, such as are likely to occur in changed land-use and global warming. This will greatly enhance knowledge about the role of rare bacterial species in ecosystems and the changes in ecosystem processes to be expected in the future.
Sound-based Emotion Estimation and Growing HRI System for an Edutainment Robot

Field: Computer Science (Physical Sciences)

This paper presents the sound-based emotion estimation method and the growing HRI (human-robot interaction) system for a Mon-E robot. The method of emotion estimation uses the musical element based on the law of harmony and counterpoint. The emotion is estimated from sound using the information of musical elements which include chord, tempo, volume, harmonic and compass. In this paper, the estimated emotions display the standard 12 emotions including Eckman's 6 emotions (anger, disgust, fear, happiness, sadness, surprise) and the opposite 6 emotions (calmness, love, confidence, unhappiness, gladness, comfortableness) of those. The growing HRI system analyzes sensing information, estimated emotion and service log in an edutainment robot. So, it commands the behavior of the robot. The growing HRI system consists of the emotion client and the emotion server. The emotion client estimates the emotion from sound. This client not only transmits the estimated emotion and sensing information to the emotion server but also delivers response coming from the emotion server to the main program of the robot. The emotion server not only updates the rule table of HRI using information transmitted from the emotion client and but also transmits the response of the HRI to the emotion client. The proposed system was applied to a Mon-E robot and can supply friendly HRI service to users.
