Acoustic function of sound hole design in musical instruments
… development of complex sound-holes such as rosettes in lute, f-hole in violin and multiple sound-holes in oud families based on a newly developed unified approach to analyze general sound-holes. We showed that the majority of the air flow passes through the near-the-edge area of the opening, …

A comparison of X-band polarization parameters with in-situ microphysical measurements in the comma head of two winter cyclones
… Habits with less circular shapes (bullet rosettes and aggregates) had greater contributions to the reflectivity compared to other habits when ZHH > 7 dBZ and ZDR > 2 dB. The presence of bullet rosettes and aggregates for similar ZHH and ZDR supports previous studies that bullet rosettes …

Analyse der Chromosomenverteilung in menschlichen Fibroblasten mittels 3D-Vielfarben Fluoreszenz in situ Hybridisierung
… of 30 G0-fibroblast nuclei and 30 prometaphase rosettes revealed a pronounced variability of chromosome territory neighbourhoods, as described by Allison D. C. et al. 1999, but in contrast to Nagele R. et al. 1995. However we noted a distinct radial order: small chromosomes were located close to …

Biological studies of Rhinocyllus conicus, Carduus thoermeri and a model of the interaction between these two species
… overwinter with lowest mortality on musk thistle rosettes; mortality was 73.6% in 1981, higher than previously reported but possibly more representative of field conditions. No overwintering mortality was observed for established rosettes of C. thoermeri. Studies of seed dispersal of C. thoermeri …

Multivalent Supramolecular Systems
… crowding in solution was revisited, since rosettes based on less bulky pyrimidines showed higher stabilities and effective molarities than the rosettes based on bulky pyrimidines. The following two chapters deal with efforts towards a supramolecular system inside a porphyrin nanoring. The …

Zebrafish Posterior Lateral Line Organogenesis Regulation by Notch Signaling
… signaling and organizes lateral line organs into rosettes independent of patterning cues normally provided by a Wnt/Fgf signaling system. We also show that the ectopic Notch signaling induces larger organs independently of proliferation and the Hippo pathway. Transplantation and RNASeq analyses …

Natural Variability in Phenolic and Sesquiterpene Constituents Among Burdock (<i>Arctium lappa</i> L. and <i>Arctium minus</i> L.) Leaves for Potential Medicinal Interests
… compounds than did smaller ones, and second year rosettes contained levels of chemical constituents three-fold higher than these found in first year rosettes. Environmental conditions of high light, frequent irrigation, and cooler temperatures increased phenolic levels in burdock leaves. The data …

Dynamic Simulation of active/inactive Chromatin Domains
… This way the formation of individual 1Mbp sized rosettes from a linear chain could be observed. Furthermore several Mbp of fiber were simulated, up to an entire chromosome and finally the entire nucleus of Drosophila Melanogaster. The simulation results were compared to experimental data and good …

Comparison of Two Techniques for Enumeration of Human B and T Lymphocytes
… was done on four subjects to confirm the EAC rosettes as B cells.</p> <p>There was a definite decrease in the number of monocytes after glass wool column separation. This led to a slight increase in the number of T cells and a slight decrease of B cells.</p> <p>A method is described which will …

Approaching the Three-Dimensional Organization of the Human Genome
… with 63-126 kbp loops aggregated to possibly rosettes connected by 63-126 kbp linkers, and predict correctly the transport of molecules by moderately obstructed diffusion excluding the Inter-Chromosomal Domain hypothesis. Correlation analyses of completely sequenced Archaea, Bacteria and …

Integrated control of Carduus thistles and ecological studies on Rhinocyllus conicus Froelich and Ceuthorhynchidius horridus (Panzer)
… until early April, and larvae occurred in rosettes from late December through late May. Teneral adults, which appeared in mid-May through June, underwent an aestival diapause during most of July through September. Adult reappearance in late September coincided with an increase in feeding. …

Étude d'impacts de l'envahissement de la châtaigne d'eau, trapa natans sur le milieu naturel de la Rivière du sud
… en émettant des stolons et de nouvelles rosettes. Trapa natans est une espèce envahissante en Amérique du Nord qui est capable de se développer et de maintenir une population à des densités extrêmement élevées lorsqu’elle se retrouve dans des conditions idéales de croissance. À ce titre, …

The Role of Arabidopsis thaliana Clade A1 Heat Shock Transcription Factors in Growth and Development
… study, plants overexpressing HSFA1b had smaller rosettes in seedlings and mature plants, longer inflorescence and early flowering. A number of candidate developmental genes identified to be regulated by HSFA1b could not be satisfactorily confirmed using the HSFA1 quadruple knockout due to the …

O-linked N-acetylglucosamine in differentiation and gene expression of mouse and human pluripotent stem cells
… in neural tube-like structures, so-called neural rosettes. Following these observations we performed mRNA sequencing analysis on human iPS cells with high O-GlcNAc levels and found gene expression to be significantly altered. Genes affected by increased O-GlcNAcylation include modulators of key …

Geology, paragenesis, and geochemistry of sphalerite mineralization at the Young mine, Mascot-Jefferson City zinc district, East Tennessee
… sphalerite occurs as fracture fillings and as rosettes between carbonate breccia blocks and displays well developed growth zoning characterized by variations in color, opacity, inclusions, and composition. Ore emplacement was preceded by two periods of solution brecciation. The first episode …

TISSUE ARCHITECTURE AND INTERCELLULAR COMMUNICATION: MEDIATORS OF PROTECTIVE OR PATHOGENIC INTERFERON RESPONSES
… that are present in tissues, such as neural rosettes found in developing brains to address the contribution of these non-immune cells. Moreover, these models allowed me to mimic physiologically relevant functions, such as migration of fetal extravillous trophoblasts into the maternal uterus …

The Role of EphA Receptor Signaling in Neuroblast Survival During In Vitro Differentiation
… we see EphA7 localization at the face of neural rosettes, where it co-expresses with markers of neuroblast identity. However, the role of Eph receptors and ephrins in neurogenesis is not well understood.</p> <p>Previous literature had shown that ephrin-A5 and EphA7 can function to balance …

Characterization of the Arabidopsis glutamine dumper1 mutant reveals connections between amino acid homeostasis and plant stress responses
… stress/defense responses, lesions, and smaller rosettes. The biochemical function of GDU1 remains elusive. To better elucidate the biological processes leading to the complex Gdu1D phenotype, two approaches were conducted: (1) An ethyl methanesulfonate suppressor screening of the Gdu1D …
