Eudorella hwanghaensis

description: The Eudorella hwanghaensis group
 Eudorella hwanghaensis Hong & Park, 1999, E. ryukyuensis Akiyama & Gamô, 2005, E. bathyhwanghaensis sp. nov., and E. suluensis sp. nov. are closely related species sharing the following characters of females. (1) Antenna 2 has plumose setae on the inferior margin. (2) The basis of maxilliped 2 has a group of setae on its inner margin. (3) The basis of pereopod 1 has 1–3 robust spiniform setae on its ventral surface. (4) The frontal margin of the carapace is serrated, (5) The propodus of pereopod 2 has a deep notch on the distal corner, reaching close to the basal end of the article. (6) The 1st article of the uropod endopod is 4 times or longer than the 2nd article.
 All these species are distributed in the vicinity of southern Japan, but the depth of the habitat of the Japanese species differ: 59–596 m in E. hwanghaensis; 576–1056 m in E. bathyhwanghaensis; and 703–1533 m in E. ryukyuensis. The shape of pereopod 3 in the adult males may be an common evolutionary trait of the E. hwanghaensis group. In E. ryukyuensis, this appendage is normal for the genus (Akiyama & Gamô 2005). The distal three articles of this appendage in E. bathyhwanghaensis show a secondary sexual character: a chela-like form. On the carpus, 1 seta on the distal end is unusually robust and curved, and the other four setae are normal for the genus (Fig. 12I). In E. hwanghaensis, adult males show a more specialized morphology of this article: two setae on the distal corner are robust and curved, and the other three setae unusually stiff and long (Fig. 26 B). Considering the specialization pattern of these three species, the ancestors of the E. hwanghaensis group probably would have migrated from the bathyal zone to shallower water, developing more specialized male sexual characters. Eudorella suluensis is distinguished from the three Japanese species by the presence of tubercles on the upper front corner of carapace, which is unique for the genus.
 Eudorella emarginata (Kröyer, 1846) shares some morphological characters with the E. hwanghaensis group, especially, (1) antenna 2 with 2–3 setae on the lower margin, and (2) the basis of pereopod 1 with 1–2 spiniform setae on the ventral surface. These characters were not observed in the other members of Japanese Eudorella. Although geographical distribution and morphology of the basis of maxilliped 2 of E. emarginata are different, this species may be related to the E. hwanghaensis group.

description: Planar squeezed states, i.e. quantum states which are squeezed in two orthogonal spin components, have recently attracted attention due to their applications in atomic interferometry and quantum information [Q. Y. He et al, New J. Phys. 14, 093012 (2012)]. While canonical variables such as quadratures of the radiation field can be squeezed in at most one component, simultaneous squeezing in two orthogonal spin components can be achieved due to the angular momentum commutation relations. We present a novel scheme for planar squeezing via quantum non-demolition (QND) measurements in spin-1 systems. The QND measurement is achieved via near-resonant paramagnetic Faraday rotation probing, and the planar squeezing is obtained by sequential QND measurement of two orthogonal spin components. We compute the achievable squeezing for a variety of optical depths, initial conditions, and probing strategies. The planar squeezed states generated in this way contain entanglement detectable by spin-squeezing inequalities and give an advantage relative to non-squeezed states for any precession phase angle, a benefit for single-shot and high-bandwidth magnetometry.

description: Here we report seasonally resolved sea surface temperatures for the southern Mozambique Channel in the SW Indian Ocean based on multi-trace-element temperature proxy records preserved in two Porites sp. coral cores. Particularly, we assess the suitability of both separate and combined Sr∕Ca and Li∕Mg proxies for improved multielement SST reconstructions. Overall, geochemical records from Europa Island Porites sp. highlight the potential of Sr∕Ca and Li∕Mg ratios as high-resolution climate proxies but also show significant differences in their response at this Indian Ocean subtropical reef site. Our reconstruction from 1970 to 2013 using the Sr∕Ca SST proxy reveals a warming trend of 0.58±0.1 ∘C in close agreement with instrumental data (0.47±0.07 ∘C) over the last 42 years (1970–2013). In contrast, the Li∕Mg showed unrealistically large warming trends, most probably caused by uncertainties around different uptake mechanisms of the trace elements Li and Mg and uncertainties in their temperature calibration. In our study, Sr∕Ca is superior to Li∕Mg to quantify absolute SST and relative changes in SST. However, spatial correlations between the combined detrended Sr∕Ca and Li∕Mg proxies compared to instrumental SST at Europa revealed robust correlations with local climate variability in the Mozambique Channel and teleconnections to regions in the Indian Ocean and southeastern Pacific where surface wind variability appeared to dominate the underlying pattern of SST variability. The strongest correlation was found between our Europa SST reconstruction and instrumental SST records from the northern tropical Atlantic. Only a weak correlation was found with ENSO, with recent warm anomalies in the geochemical proxies coinciding with strong El Niño or La Niña. We identified the Pacific–North American (PNA) atmospheric pattern, which develops in the Pacific in response to ENSO, and the tropical North Atlantic SST as the most likely causes of the observed teleconnections with the Mozambique Channel SST at Europa.

Observation of the TeV gamma-ray source MGRO J1908+06 with ARGO-YBJ

description: The extended gamma ray source MGRO J1908+06, discovered by the Milagro air shower detector in 2007, has been observed for about 4 years by the ARGO-YBJ experiment at TeV energies, with a statistical significance of 6.2 standard deviations. The peak of the signal is found at a position consistent with the pulsar PSR J1907+0602. Parametrizing the source shape with a two-dimensional Gauss function we estimate an extension σ= 0.49 \pm 0.22 degrees, consistent with a previous measurement by the Cherenkov Array H.E.S.S.. The observed energy spectrum is dN/dE = 6.1 \pm 1.4 \times 10^-13 (E/4 TeV)^{-2.54 \pm 0.36} photons cm^-2 s^-1 TeV^-1, in the energy range 1-20 TeV. The measured gamma ray flux is consistent with the results of the Milagro detector, but is 2-3 times larger than the flux previously derived by H.E.S.S. at energies of a few TeV. The continuity of the Milagro and ARGO-YBJ observations and the stable excess rate observed by ARGO-YBJ along 4 years of data taking support the identification of MGRO J1908+06 as the steady powerful TeV pulsar wind nebula of PSR J1907+0602, with an integrated luminosity above 1 TeV about 1.8 times the Crab Nebula luminosity.

A quantitative system for discriminating induced pluripotent stem cells, embryonic stem cells and somatic cells
Creators: name: Wang, Anyou

Year: 2012
Subjects: subject: Quantitative Methods (q-bio.QM)
subject: FOS: Biological sciences

description: Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) derived from somatic cells (SCs) provide promising resources for regenerative medicine and medical research, leading to a daily identification of new cell lines. However, an efficient system to discriminate the cell lines is lacking. Here, we developed a quantitative system to discriminate the three cell types, iPSCs, ESCs and SCs. The system contains DNA-methylation biomarkers and mathematical models, including an artificial neural network and support vector machines. All biomarkers were unbiasedly selected by calculating an eigengene score derived from analysis of genome-wide DNA methylations. With 30 biomarkers, or even with as few as 3 top biomarkers, this system can discriminate SCs from ESCs and iPSCs with almost 100% accuracy, and with approximately 100 biomarkers, the system can distinguish ESCs from iPSCs with an accuracy of 95%. This robust system performs precisely with raw data without normalization as well as with converted data in which the continuous methylation levels are accounted. Strikingly, this system can even accurately predict new samples generated from different microarray platforms and the next-generation sequencing. The subtypes of cells, such as female and male iPSCs and fetal and adult SCs, can also be discriminated with this system. Thus, this quantitative system works as a novel general and accurate framework for discriminating the three cell types, iPSCs, ESCs, and SCs and this strategy supports the notion that DNA-methylation generally varies among the three cell types.

description: In 2015, Germany entered what would later become known as the ‘refugee crisis’. The Willkommenskultur (welcoming culture) trope gained political prominence and met with signifi cant challenges. In this article, we focus on a series of encounters in Berlin, bringing together refugee newcomers, migrants, activists and anthropologists. As we thought and wrote together about shared experiences, we discovered the limitations of the normative assumptions of refugee work. One aim of this article is to destabilise terms such as refugee, refugee work, success and failure with our engagements in the aftermath of the ‘crisis’. Refugee work is not exclusively humanitarian aid directed towards the alleviation of suff ering but includes being and doing together. Through productive failures and emergent lessons, the collaboration enhanced our understandings of social categories and the role of anthropology.

description: Statistical methods of presenting experimental results in constraining the neutrino mass hierarchy (MH) are discussed. Two problems are considered and are related to each other: how to report the findings for observed experimental data, and how to evaluate the ability of a future experiment to determine the neutrino mass hierarchy, namely, sensitivity of the experiment. For the first problem where experimental data have already been observed, the classical statistical analysis involves constructing confidence intervals for the parameter Δm^2_{32}. These intervals are deduced from the parent distribution of the estimation of Δm^2_{32} based on experimental data. Due to existing experimental constraints on |Δm^2_{32}|, the estimation of Δm^2_{32} is better approximated by a Bernoulli distribution (a Binomial distribution with 1 trial) rather than a Gaussian distribution. Therefore, the Feldman-Cousins approach needs to be used instead of the Gaussian approximation in constructing confidence intervals. Furthermore, as a result of the definition of confidence intervals, even if it is correctly constructed, its confidence level does not directly reflect how much one hypothesis of the MH is supported by the data rather than the other hypothesis. We thus describe a Bayesian approach that quantifies the evidence provided by the observed experimental data through the (posterior) probability that either one hypothesis of MH is true. This Bayesian presentation of observed experimental results is then used to develop several metrics to assess the sensitivity of future experiments. Illustrations are made using a simple example with a confined parameter space, which approximates the MH determination problem with experimental constraints on the |Δm^2_{32}|.

description: To understand processes in urban environments, such as urban energy fluxes or surface temperature patterns, it is important to map urban surface materials. Airborne imaging spectroscopy data have been successfully used to identify urban surface materials mainly based on unmixing algorithms. Upcoming spaceborne Imaging Spectrometers (IS), such as the Environmental Mapping and Analysis Program (EnMAP), will reduce the time and cost-critical limitations of airborne systems for Earth Observation (EO). However, the spatial resolution of all operated and planned IS in space will not be higher than 20 to 30 m and, thus, the detection of pure Endmember (EM) candidates in urban areas, a requirement for spectral unmixing, is very limited. Gradient analysis could be an alternative method for retrieving urban surface material compositions in pixels from spaceborne IS. The gradient concept is well known in ecology to identify plant species assemblages formed by similar environmental conditions but has never been tested for urban materials. However, urban areas also contain neighbourhoods with similar physical, compositional and structural characteristics. Based on this assumption, this study investigated (1) whether cover fractions of surface materials change gradually in urban areas and (2) whether these gradients can be adequately mapped and interpreted using imaging spectroscopy data (e.g. EnMAP) with 30 m spatial resolution. Similarities of material compositions were analysed on the basis of 153 systematically distributed samples on a detailed surface material map using Detrended Correspondence Analysis (DCA). Determined gradient scores for the first two gradients were regressed against the corresponding mean reflectance of simulated EnMAP spectra using Partial Least Square regression models. Results show strong correlations with R2 = 0.85 and R2 = 0.71 and an RMSE of 0.24 and 0.21 for the first and second axis, respectively. The subsequent mapping of the first gradient reveals patterns that correspond to the transition from predominantly vegetation classes to the dominance of artificial materials. Patterns resulting from the second gradient are associated with surface material compositions that are related to finer structural differences in urban structures. The composite gradient map shows patterns of common surface material compositions that can be related to urban land use classes such as Urban Structure Types (UST). By linking the knowledge of typical material compositions with urban structures, gradient analysis seems to be a powerful tool to map characteristic material compositions in 30 m imaging spectroscopy data of urban areas.

Ένα μοντέλο τριών παραγόντων αποτίμησης των Fama and French (1993) φάνηκε να μπορεί να εντοπίσει τη διακύμανση της απόδοσης των μετοχών, εξηγώντας πως η απόδοση εξαρτάται από τη σχέση της με τρεις παράγοντες: 1) τις αποδόσεις στο χαρτοφυλάκιο της αγοράς (παράγοντας αγοράς/market factor), 2) τη διαφορά μεταξύ των αποδόσεων ενός χαρτοφυλακίου με μετοχές μικρής κεφαλαιοποίησης και ενός μεγάλης κεφαλαιοποίησης (παράγοντας μεγέθους/ SBM) και 3) τη διαφορά μεταξύ των αποδόσεων ενός χαρτοφυλακίου με υψηλή και ενός με χαμηλή αναλογία book-to-market (BE/ME) (παράγοντας αξίας/ HML). Στη μελέτη Carhart (1997) προτάθηκε και ένας τέταρτος παράγοντας σε σχέση με το momentum (WML.) και έτσι δημιουργήθηκε το μοντέλο των τεσσάρων παραγόντων. Και τα δύο μοντέλα έχουν αποτελέσει τη βάση πολλών ερευνών, σχετικά με τη στατιστική σημαντικότητα των αποτελεσμάτων τους. Πολλές από αυτές υποστηρίζουν τα δύο μοντέλα, ενώ άλλες τα αμφισβητούν. Το μοντέλο των τεσσάρων παραγόντων εστιάζει στην αξία, το μέγεθος και το momentum, χωρίς να λαμβάνει υπόψη άλλους παράγοντες κινδύνου που μπορεί να παίζουν ρόλο στην απόδοση των μετοχών, όπως ο συναλλαγματικός κίνδυνος (N. Apergis et al, 2011). Κύριος στόχος αυτής της εργασίας είναι να αποδείξει ότι ο συναλλαγματικός κίνδυνος αποτελεί παράγοντα αποτίμησης περιουσιακών στοιχείων. Αυτό γίνεται μέσω της διερεύνησης της επίπτωσης ενός χαρτοφυλακίου, με παράγοντα που μιμείται τον συναλλαγματικό κίνδυνο, στην ερμηνεία της διακύμανσης των αποδόσεων των μετοχών.

Βασιζόμενοι στην προσέγγιση Παλινδρόμησης μέσω χρονοσειρών των Black et al. (1972), όπως αναφέρεται και από τους Fama and French (1993), μπορούμε να διευκρινίσουμε εάν το μιμητικό χαρτοφυλάκιο μπορεί να αποτυπώσει τη διακύμανση στις αποδόσεις (που δεν εξηγείται από άλλους παράγοντες) και εάν το ερευνητικό μοντέλο αποτελεί μοντέλο αποτίμησης δημιουργώντας intercepts, μη στατιστικά σημαντικά ή που τείνουν στο μηδέν (Merton, 1973) (N.

description: In this work we provide a proof of principle for a theoretical methodology to identify functionalisation patterns in oxidised carbon 2D nanomaterials. The methodology is based on calculating a large number of X-ray absorption spectra of individually excited carbon atoms in different chemical environments using density functional theory. Since each resulting spectrum gives a fingerprint of the local electronic structure surrounding the excited atom, we may relate each spectrum to the functionalisation pattern of that excited atom up to a desired neighbourhood radius. These functionalisation pattern-specific spectra are collected in a database, that allows fast composition of X-ray absorption spectra for arbitrary structures in density functional theory quality. Finally, we present an exemplary application of the database approach to estimate the relative amount of functional groups in two different experimental samples of carbon nanomaterials.

description: Background Long non-coding RNAs (lncRNAs) play an important role in regulating gene expression and are thus important for determining phenotypes. Most attempts to measure selection in lncRNAs have focused on the primary sequence. The majority of small RNAs and at least some parts of lncRNAs must fold into specific structures to perform their biological function. Comprehensive assessments of selection acting on RNAs therefore must also encompass structure. Selection pressures acting on the structure of non-coding genes can be detected within multiple sequence alignments. Approaches of this type, however, have so far focused on negative selection. Thus, a computational method for identifying ncRNAs under positive selection is needed. Results We introduce the SSS-test (test for Selection on Secondary Structure) to identify positive selection and thus adaptive evolution. Benchmarks with biological as well as synthetic controls yield coherent signals for both negative and positive selection, demonstrating the functionality of the test. A survey of a lncRNA collection comprising 15,443 families resulted in 110 candidates that appear to be under positive selection in human. In 26 lncRNAs that have been associated with psychiatric disorders we identified local structures that have signs of positive selection in the human lineage. Conclusions It is feasible to assay positive selection acting on RNA secondary structures on a genome-wide scale. The detection of human-specific positive selection in lncRNAs associated with cognitive disorder provides a set of candidate genes for further experimental testing and may provide insights into the evolution of cognitive abilities in humans.

description: We study the second quantized -or guiding center- description of the torus Laughlin state. Our main focus is the change of the guiding center degrees of freedom with the torus geometry, which we show to be generated by a two-body operator. We demonstrate that this operator can be used to evolve the full torus Laughlin state at given modular parameter τ from its simple (Slater-determinant) thin torus limit, thus giving rise to a new presentation of the torus Laughlin state in terms of its "root partition" and an exponential of a two-body operator. This operator therefore generates in particular the adiabatic evolution between Laughlin states on regular tori and the quasi-one-dimensional thin torus limit. We make contact with the recently introduced notion of a "Hall viscosity" for fractional quantum Hall states, to which our two-body operator is naturally related, and which serves as a demonstration of our method to generate the Laughlin state on the torus.

description: We show that that the non-equilibrium spin polarization of one dimensional helical edge states at the boundary of a two dimensional topological insulator can dynamically induce a polarization of nuclei via the hyperfine interaction. When combined with a spatially inhomogeneous Rashba coupling, the steady state polarization of the nuclei produces backscattering between the topologically protected edge states leading to a reduction in the conductance which persists to zero temperature. We study these effects in both short and long edges, uncovering deviations from Ohmic transport at finite temperature and a current noise spectrum which may hold the fingerprints for experimental verification of the backscattering mechanism.

Stability and structure of an anisotropically trapped dipolar Bose-Einstein condensate: angular and linear rotons

description: We study theoretically Bose-Einstein condensates with polarized dipolar interactions in anisotropic traps. We map the parameter space by varying the trap frequencies and dipolar interaction strengths and find an irregular-shaped region of parameter space in which density-oscillating condensate states occur, with maximum density away from the trap center. These density-oscillating states may be biconcave (red-blood-cell-shaped), or have two or four peaks. For all trap frequencies, the condensate becomes unstable to collapse for sufficiently large dipole interaction strength. The collapse coincides with the softening of an elementary excitation. When the condensate mode is density-oscillating, the character of the softening excitation is related to the structure of the condensate. We classify these excitations by linear and angular characteristics. We also find excited solutions to the Gross-Pitaevskii equation, which are always unstable.

description: We report a strong correlation between the calculated broadband circular differential optical absorption (CDOA) and the geometric chirality of plasmonic meta-atoms with two-dimensional chirality. We investigate this correlation using three common gold meta-atom geometries: L-shapes, triangles, and nanorod dimers, over a broad range of geometric parameters. We show that this correlation holds for both contiguous plasmonic meta-atoms and non-contiguous structures which support plasmonic coupling effects. A potential application for this correlation is the rapid optimization of plasmonic nanostructure for maximum broadband CDOA.

description: Galaxy clusters are the most massive objects in the Universe and comprise a high-temperature intracluster medium of about 10^7 K, believed to offer a main foreground effect for cosmic microwave background (CMB) data in the form of the thermal Sunyaev-Zel'dovich (SZ) effect. This assumption has been confirmed by SZ signal detection in hundreds of clusters but, in comparison with the huge numbers of clusters within optically selected samples from Sloan Digital Sky Survey (SDSS) data, this only accounts for a few per cent of clusters. Here we introduce a model-independent new method to confirm the assumption that most galaxy clusters can offer the thermal SZ signal as their main foreground effect. For the Wilkinson Microwave Anisotropy Probe (WMAP) seven-year data (and a given galaxy cluster sample), we introduced a parameter d1 as the nearest-neighbour cluster angular distance of each pixel, then we classified data pixels as 'to be' (d1--> 0 case) or 'not to be' (d1 large enough) affected by the sample clusters. By comparing the statistical results of these two kinds of pixels, we can see how the sample clusters affect the CMB data directly. We find that the Planck Early Sunyaev-Zel'dovich (ESZ) sample and X-ray samples (~10^2 clusters) can lead to obvious temperature depression in the WMAP seven-year data, which confirms the SZ effect prediction. However, each optically selected sample (>10^4 clusters) shows an opposite result: the mean temperature rises to about 10uK. This unexpected qualitative scenario implies that the main foreground effect of most clusters is $not$ always the expected SZ effect. This may be the reason why the SZ signal detection result is lower than expected from the model.

description: Recent studies investigating groundwater parameters, e.g., heads, chemical composition, and heat transfer, argued that groundwater flow paths in the Lower Yarmouk Gorge (LYG) area are controlled by geological features such as faults or dikes. However, the nature of such features, as well as their exact locations, were so far unknown. In the present paper, we propose a new fault pattern in the LYG area by compiling and revising geological and geophysical data from the study area, including borehole information, geological map cross sections, and seismic data from the southern Golan Heights and northern Ajloun mountains. The presented pattern is composed of strike–slip and thrust faults, which are associated with the Dead Sea transform system and with the Kinnarot pull-apart basin. Compressional and tensional structures developed in different places, forming a series of fault blocks probably causing a non-uniform spatial hydraulic connection between them. This study provides a coarse fault-block model and improved structural constraints that serve as fundamental input for future hydrogeological modeling which is a suggested solution for an enigmatic hydrological situation concerning three riparian states (Syria, Jordan, and Israel) in a water-scarce region. In areas of water scarcity and transboundary water resources, transient 3-D flow simulations of the resource are the most appropriate solution to understand reservoir behavior. This is an important tool for the development of management strategies. However, those models must be based on realistic geometry, including structural features. The study at the LYG is intended to show the importance of such kinds of structural investigations for providing the necessary database in geologically stressed areas without sufficient data. Furthermore, during the hydrogeological investigation, a mismatch with results of pull-apart basin rim fault evolution studies was discovered. We argue that this mismatch may result from the settings at the eastern rim of the basin as the en-echelon changes from pull-apart basins (Dead Sea, Kinnarot, Hula) to a push-up ridge (Hermon).

description: Hepatitis E virus (HEV) is the causative agent of acute hepatitis E in humans in developing countries, but autochthonous cases of zoonotic genotype 3 (HEV-3) infection also occur in industrialized countries. In contrast to swine, rats, and rabbits, natural HEV infections in mice have not yet been demonstrated. The pig represents a well-established large animal model for HEV-3 infection, but a suitable small animal model mimicking natural HEV-3 infection is currently missing. Therefore, we experimentally inoculated C57BL/6 mice (wild-type, IFNAR−/−, CD4−/−, CD8−/−) and BALB/c nude (nu/nu) mice, Wistar rats, and European rabbits with a wild boar-derived HEV-3 strain and monitored virus replication and shedding, as well as humoral immune responses. HEV RNA and anti-HEV antibodies were detected in one and two out of eight of the rats and all rabbits inoculated, respectively, but not in any of the mouse strains tested. Remarkably, immunosuppressive dexamethasone treatment of rats did not enhance their susceptibility to HEV infection. In rabbits, immunization with recombinant HEV-3 and ratHEV capsid proteins induced protection against HEV-3 challenge. In conclusion, the rabbit model for HEV-3 infection may serve as a suitable alternative to the non-human primate and swine models, and as an appropriate basis for vaccine evaluation studies.

description: A lo largo de los siglos, las memorias acerca de la conquista han sido moldeadas por diversos proyectos políticos, comenzando por aquellos que establecieron la nueva sociedad virreinal. Este artículo explora cómo los habitantes de la Nueva España mediaron a través de textos, imágenes y artefactos sus propias memorias de los eventos de 1519-1521 para legitimar sus demandas por las recompensas o un estatus social privilegiado. Argumenta que las luchas distributivas dieron forma a las prácticas de memorialización con las que se llevaba el pasado al presente y se pone al servicio del futuro, así como las interacciones entre un mundo textual y material que plasmaron las memorias de la conquista.

description: The paper deals with the results of an analysis of the spatial structure of agriculture in Poland which was aimed at assessing the impact of the historical factor. The territory of present-day Poland includes the political borders of the 19th and 20th centuries which divided the area into two parts: western (Kingdom of Prussia and the land belonging to Poland and Germany in the interwar period) and eastern (the land of the Russian Empire and the Austro-Hungarian Empire which later belonged to Poland in the interwar period). The historical factor and its impact were examined also in the comparative analysis of two adjoining stretches of land accepted as territorial units (East Poland and West Poland). We showed that historical borders constitute an important element affecting the evolution of the spatial structure of Polish agriculture. The impact of the historical factor was shown to be the strongest for the differences in the features associated with agrarian structure, rural socio-demography, and productivity and profitability of agricultural holdings.

description: Human blood group related glycan antigens are fucosylated (neo-)lactoseries oligosaccharides that play crucial roles in pathogenic processes. Lewis type-II-chain antigens mark the surface of cancer cells, but are also mediators of bacterial infections. To investigate the biological roles of Lewis type glycans a host of synthetic approaches has been developed. Here, we illustrate how automated glycan assembly (AGA) using a set of six monosaccharide building blocks provides quick access to a series of more than ten defined Lewis type-I and type-II antigens, including Lex, Ley, Lea, Leb and KH-1. Glycans with up to three α-fucose branches were assembled following a strictly linear approach and obtained in excellent stereoselectivity and purity.

description: We consider a preferential cluster growth in a one-dimensional stochastic model describing the dynamics of a binary chain with long-range memory. The model is driven by data corresponding to emotional patterns observed during online communities' discussions. The system undergoes a dynamical phase transition. For low values of the preference exponent, both states are observed during the string evolution in the majority of simulated discussion threads. When the exponent crosses a critical value, in the majority of threads an ordered phase emerges, i.e. from a certain time moment only one state is represented. The transition becomes discontinuous in the thermodynamical limit when the discussions are infinitely long and even an infinitely small preference exponent leads to the ordering behavior in every discussion thread. Numerical simulations are in a good agreement with approximated analytical formula.
