title: Genetic Control of Spermiogenesis in Drosophila melanogaster: The Effects of Abnormal Association of Centrosome and Nucleus in Mutant MS(1)6S
Creators: name: Habliston, Douglas Lee
Publisher: name: Utah State University
Year: 1977

description: Mutant ms(l)6S of Drosophila melanogaster is characterized by a spectrum of abnormalities of spermatid differentiation. Included in these are failure of the basal body to make normal attachment to the nucleus, failure of acrosomes to develop, and lack of a normal pupulation of perinuclear microtubules. There is also a failure of normal chromatin condensation and nuclear elongation. The mitochondria do not form a normaI nebenkern, but nevertheless fuse, elongate, and develop paracrystalline bodies. The number of normal axonemes is markedly reduced as a result of the failure of some centrioles to form basal bodies. All of these aberrations can be related to defective interactions of the "centrosome" or "microtubule-organizing-centre" with other organelles. The analysis of spermiogenesis in this mutant further clarifies the roles of microtubules in nuclear condensation and elongation and in ceIlular elongation in generaI.

description: We use the AdS/CFT correspondence to compute the drag force experienced by a heavy quark moving through a maximally supersymmetric SU(N) super Yang-Mills plasma at nonzero temperature and R-charge chemical potential and at large 't Hooft coupling. We resolve a discrepancy in the literature between two earlier studies of such quarks. In addition, we consider small fluctuations of the spinning strings dual to these probe quarks and find no evidence of instabilities. We make some comments about suitable D7-brane boundary conditions for the dual strings.

description: Chondrules are often surrounded by fine-grained rims or igneous rims. The properties of these rims reflect their formation histories. While the formation of fine-grained rims is modeled by the accretion of dust grains onto chondrules, the accretion should be followed by the growth of dust grains due to the shorter growth timescale than the accretion. In this paper, we investigate the formation of rims, taking into account the growth of porous dust aggregates. We estimate the rim thickness as a function of the chondrule fraction at a time when dust aggregate accretion onto chondrules is switched to collisions between these chondrules. Our estimations are consistent with the measured thicknesses of fine-grained rims in ordinary chondrites. However, those of igneous rims are thicker than our estimations. The thickness of igneous rims would be enlarged in remelting events.

description: We present a comprehensive survey of CII* absorption detections toward stars within 100 pc in order to measure the distribution of electron densities present in the local interstellar medium (LISM). Using high spectral resolution observations of nearby stars obtained by GHRS and STIS onboard the Hubble Space Telescope, we identify 13 sight lines with 23 individual CII* absorption components, which provide electron density measurements, the vast majority of which are new. We employ several strategies to determine more accurate CII column densities from the saturated CII resonance line, including, constraints of the line width from the optically thin CII* line, constraints from independent temperature measurements of the LISM gas based on line widths of other ions, and third, using measured SII column densities as a proxy for CII column densities. The sample of electron densities appears consistent with a log-normal distribution and an unweighted mean value of n_e(CII_SII) = 0.11^+0.10_-0.05 cm^-3. Seven individual sight lines probe the Local Interstellar Cloud (LIC), and all present a similar value for the electron density, with a weighted mean of n_e(LIC) = 0.12 +/- 0.04 cm^-3. The Hyades Cloud, a decelerated cloud at the leading edge of the platoon of LISM clouds, has a significantly higher electron density than the LIC. Observed toward G191-B2B, the high electron density may be caused by the lack of shielding from such a strong radiation source. Given some simple assumptions, the range of observed electron densities translates into a range of thermal pressures, P/k = 3300^+5500_-1900 K cm^-3. This work greatly expands the number of electron density measurements and provides important constraints on the ionization, abundance, and evolutionary models of the local interstellar medium.

title: Influence of Corynebacterium insidiosum on the Water Relations of Alfalfa
Creators: name: Dey, Rastri
Publisher: name: Utah State University
Year: 1977

description: The effect of Corynebacterium insidiosum (McCull) H. L. Jensen on the water relations of its host, alfalfa, was studied by field measurements made on a 6-year-old stand of Ranger alfalfa. Periodic measurements of stomatal conductance, xylem pressure potential Ψ, and root, stem, and leaf conductance were made in relation to soil moisture conditions. Water regain and electrolyte leakage studies were also made to test membrane integrity in diseased plant leaves.
At all times the xylem pressure potential Ψ was found to be much more negative in diseased plants than in healthy plants. Stomatal conductance was found to respond to the Ψ values in both diseased and healthy plants, indicating no impairment of stomatal function in diseased plants. Liquid flow conductance was found to be adversely affected in diseased plants. Flow of water through leaflet veins was found to be 60 times less in diseased than in healthy leaflets. No evidence was found in water regain or electrolyte leakage studies to suggest cellular membrane damage. Counts of bacterial colonies as related to liquid flow conductance studies indicated that location of impairment of water movement was not correlated with the location of the greatest numbers of bacteria.

description: Based on molecular, morphological and field data, the status and zoogeography of the taxa of the Psammophissibilans group north of 12°S are reviewed. Molecular data including sequences from 20 of the 22 described species known to occur north of 12°S suggest that P. sibilans distribution is restricted to northeastern Africa, from Egypt to Ethiopia. Po-pulations from West Africa are described as a new species, P. afroccidentalis sp. nov., and those from Chad, Cameroon and Central African Republic are assigned to P. rukwae which is also distributed from Tanzania to Ethiopia. Molecular data indicate the occurrence within this complex of three additional cryptic species in the Horn of Africa. Populations previous-ly assigned to P. phillipsi in Central Africa north, south and east of the Congo forest block are assigned to P. mossambicus and the status of P. occidentalis is discussed. P. phillipsi is restricted to West Africa, with P. irregularis as junior synonym.

description: We study the three-body problem for three atomic fermions, in the same spin state, experiencing a resonant interaction in the p-wave channel via a Feshbach resonance represented by a two-channel model. The rate of inelastic processes due to recombination to deeply bound dimers is then estimated from the three-body solution using a simple prescription. We obtain numerical and analytical predictions for most of the experimentally relevant quantities that can be extracted from the three-body solution: the existence of weakly bound trimers and their lifetime, the low-energy elastic and inelastic scattering properties of an atom on a weakly bound dimer (including the atom-dimer scattering length and scattering volume), and the recombination rates for three colliding atoms towards weakly bound and deeply bound dimers. The effect of "background" non-resonant interactions in the open channel of the two-channel model is also calculated and allows to determine which three-body quantities are `universal' and which on the contrary depend on the details of the model.

description: Many systems in nature, glasses, interfaces and fractures being some examples, cannot equilibrate with their environment, which gives rise to novel and surprising behaviour such as memory effects, ageing and nonlinear dynamics. Unlike their equilibrated counterparts, the dynamics of out-of- equilibrium systems is generally too complex to be captured by simple macroscopic laws. Here we investigate a system that straddles the boundary between glass and crystal: a Bragg glass formed by vortices in a superconductor. We find that the response to an applied force evolves according to a stretched exponential, with the exponent reflecting the deviation from equilibrium. After the force is removed, the system ages with time and its subsequent response time scales linearly with its age (simple ageing), meaning that older systems are slower than younger ones. We show that simple ageing can occur naturally in the presence of sufficient quenched disorder. Moreover, the hierarchical distribution of timescales, arising when chunks of loose vortices cannot move before trapped ones become dislodged, leads to a stretched-exponential response.

description: The target group of this document are urban practitioners who want to walk the talk of co-creation beyond the common practice of developing plans in a collaborative spirit between the municipality and citizens and local stakeholders. To fully harness the benefits of co-creation, similar coalitions should engage jointly in co-implementation efforts. This document therefore clarifies key terms and delineates co-implementation from related concepts. It also articulates important benefits of co-implementation while being clear about related risks and challenges. Of particular value to practitioners are the lists of potential civic actors and their potential types of contributions. The document also provides inspiration of what co-implementation in action could look like through references to a number of existing initiatives. It also includes hands on “how-to” tips to consider before and during co-implementation activities.
The experience of underemployment for male college graduates
Creators: name: Harder, Henry G.
Publisher: name: University of British Columbia
Year: 2010

description: An exploratory study was conducted in order to discover significant events and feelings attached to those events during the experience of underemployment for male college graduates. Fifteen male college graduates of varying ages and post-secondary degrees were interviewed. The qualitative/critical incident methodology adapted by Borgen and Amundson (1984) was used. The experience was found to be comprised of four segments: an initial down period during job search after graduation; an upward partially high period upon receiving employment; a downward spiral as the experience takes hold; and a time when the person either decides to make things change or decides to give up and accept the situation. The results and description of this experience may aid counsellors in developing more effective therapeutic interventions for this population.

Hall data indicate that the dominant carriers are electrons, as expected from simple chemical reasoning. This is the first example of superconductivity induced by electron doping in this family of materials. In contrast to the cuprates, the BaFe2As2 system appears to tolerate considerable disorder in the FeAs planes. First principles calculations for BaFe1.8Co0.2As2 indicate the inter-band scattering due to Co is weak.

The framework's intended main use case of is testing the family of Extended Reality (XR) based systems (e.g. 3D games, VR sytems, AR systems), though the approach can indeed be adapted to target other types of interactive systems. The framework is unique in that it is an agent-based system. Agents are inherently reactive, and therefore are arguably a natural match to deal with interactive systems. Moreover, it is also a natural vessel for mounting and combining different AI capabilities, e.g. reasoning, navigation, and learning.

description: Unintended effects of gene edit crops may pose safety issues. Omics is a useful tool for researchers to evaluate these unexpected effects. Transcriptome and proteomics analyses were performed for two gene editors, CRISPR-Cas9 and adenine base editor (ABE) gene edit rice, as well as corresponding wild-type plants (Nipponbare). Transcriptome revealed 520 and 566 rice differentially expressed genes (DEGs) in the Cas9/Nip and ABE/Nip comparisons, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that most DEGs participated in metabolism of terpenoids and polyketones, plant–pathogen interactions, and plant signal transduction. It mainly belongs to environmental adaptation. Proteomics revealed 298 and 54 rice differentially expressed proteins (DEPs) in the Cas9/Nip and ABE/Nip comparisons, respectively. KEGG pathway enrichment analysis showed that most DEPs participated in the biosynthesis of secondary metabolite and metabolic pathways. According to integrated transcriptomes and proteomics analysis, the results showed that no newly generated genes were identified as new transcripts of these differentially expressed genes, and gene edit tools had little effect on rice transcription levels and no new proteins were generated in the gene-edited rice.
title: Simulation of Wind Dispersal of Tree Seeds, Tree Colonization, and Growth of Bottomland Hardwood Reforestation Sites of the Mississippi Alluvial Valley
Creators: name: Nuttle, Timothy James
Publisher: name: Utah State University
Year: 2003

description: Tree community composition in bottomland hardwood reforestation sites is considerably less diverse than natural bottomland hardwood forests. This study sought to understand the mechanisms behind failure to develop diverse tree communities. First, I developed a mechanistic model of seed dispersal by wind in spatially variable environments. Second, I developed a spatially explicit simulation model of forest dynamics that includes this wind-dispersal model to investigate whether diversity is limited by dispersal or interactions among species and individuals. Finally, I performed model experiments to determine if manipulations of stand structure might help improve conditions for colonization of various species, thus enhancing diversity of reforestation sites. The wind dispersal model was unbiased and accurate for predicting seed dispersal patterns of four species of wind-dispersed trees, demonstrating the utility of my algorithm for making predictions of seed arrival in a forest simulation model. The forest simulation model accurately predicted basal area growth and general patterns of species relative abundance in natural and reforested bottomland hardwoods, and predicted that reforestation sites will probably never attain diversity levels of natural forests under the current management scenario. Development of diversity was hindered by competition from the species planted and limited dispersal from forests. Hence, the only reasonably successful option to enhance diversity is probably to establish sites with mixed-species plantings at the outset. However, if stands are thinned at relatively young ages (15 yr for acorn-established stands, 25 yr for seedling-established stands), before canopy closure from planted individuals results in mortality of colonizing individuals, diversity may be enhanced if adequate numbers of colonizers are able to disperse to the site. Further research is necessary on mechanistic dispersal by animals, transition rates from seeds to seedlings, and the factors that affect such transitions in order to more accurately predict forest community development.

description: Doubled haploid (DH) production accelerates the development of homozygous lines in a single generation. In maize, haploids are widely produced by the use of haploid inducer Stock 6, earlier reported in 1959. Three independent studies reported haploid induction in maize which is triggered due to a 4 bp frame-shift mutation in matrilineal (ZmPLA1) gene. The present study was focused on the generation of mutants for ZmPLA1 gene in maize inbred line LM13 through site-directed mutagenesis via CRISPR/Cas9-mediated ribonucleoprotein (RNP) complex method to increase the haploid induction rate. Three single guide RNAs (sgRNAs) for the ZmPLA1 gene locus were used for transforming the 14 days old immature embryos via bombardment. 373 regenerated plants were subjected to mutation detection followed by Sanger’s sequencing. Out of three putative mutants identified, one mutant depicted one base pair substitution and one base pair deletion at the target site.
Effects of 2013 Cap reform on land market: regionalized farm payments and changes in farmers’ intended behaviour

description: The CAP reform process has been a central issue for agricultural economics research in recent years, and is gaining further attention in view of the post-2013 perspectives (Viaggi et al., 2010; Bartolini et al., 2011). Today the CAP is in the middle of a new reform process. Through the debate generated by the official proposals, published in October 2011 (COM(2011)625/3), the European Union (EU) engaged in a revision of the CAP ended on 26 June 2013 when a political agreement has been reached (IP/13/613, MEMO-13-621 and IP/13/864). In particular, in Italy the switch of the payment regime from historical to regional bases will take place. The underlying assumption is that the shift to regionalized payments changes the remuneration of inputs and has an impact on farmers’ allocation of fixed resources. In this context, farmers are expected to adjust their plans to the new policy environment as the regionalization of support is meant to create a change in incentives faced by farmers. The objective of this thesis is to provide an ex-ante analysis of the potential impact of the introduction of regionalized payments, within the post-2013 CAP reform, on the land market. Regionalized payments seem to produce differentiated effects and contribute to  a general (slight) increase of land exchanges. The individual reaction to the new payments introduction would be different depending on location and specialization. These effects seem to be also strongly influenced by the difference in historical payments endowment and value, i.e. by the previous historical system of distribution of payments.

description: Optical frequency combs provide equidistant frequency markers in the infrared, visible and ultra-violet and can link an unknown optical frequency to a radio or microwave frequency reference. Since their inception frequency combs have triggered major advances in optical frequency metrology and precision measurements and in applications such as broadband laser-based gas sensing8 and molecular fingerprinting. Early work generated frequency combs by intra-cavity phase modulation while to date frequency combs are generated utilizing the comb-like mode structure of mode-locked lasers, whose repetition rate and carrier envelope phase can be stabilized. Here, we report an entirely novel approach in which equally spaced frequency markers are generated from a continuous wave (CW) pump laser of a known frequency interacting with the modes of a monolithic high-Q microresonator13 via the Kerr nonlinearity. The intrinsically broadband nature of parametric gain enables the generation of discrete comb modes over a 500 nm wide span (ca. 70 THz) around 1550 nm without relying on any external spectral broadening. Optical-heterodyne-based measurements reveal that cascaded parametric interactions give rise to an optical frequency comb, overcoming passive cavity dispersion. The uniformity of the mode spacing has been verified to within a relative experimental precision of 7.3*10(-18).

description: Remote synchronization implies that oscillators interacting not directly but via an additional unit (hub) adjust their frequencies and exhibit frequency locking while the hub remains asynchronous. In this paper, we analyze the mechanisms of remote synchrony in a small network of three coupled Stuart-Landau oscillators using recent results on high-order phase reduction. We analytically demonstrate the role of two factors promoting remote synchrony. These factors are the non-isochronicity of oscillators and the coupling terms appearing in the second-order phase approximation. We show a good correspondence between our theory and numerical results for small and moderate coupling strengths.

Massive stars and globular cluster formation

Subjects: subject: Astrophysics (astro-ph)

description: We first present chemodynamical simulations to investigate how stellar winds of massive stars influence early dynamical and chemical evolution of forming globular clusters (GCs). In our numerical models, GCs form in turbulent,high-density giant molecular clouds (GMCs), which are embedded in a massive dark matter halo at high redshifts. We show how high-density, compact stellar systems are formed from GMCs influenced both by physical processes associated with star formation and by tidal fields of their host halos. We also show that chemical pollution of GC-forming GMCs by stellar winds from massive stars can result in star-to-star abundance inhomogeneities among light elements (e.g., C, N, and O) of stars in GCs. The present model with a canonical initial mass function (IMF) also shows a C-N anticorrelation that stars with smaller [C/Fe] have larger [N/Fe] in a GC. Although these results imply that ``self-pollution'' of GC-forming GMCs by stellar winds from massive stars can cause abundance inhomogeneities of GCs, the present models with different parameters and canonical IMFs can not show N-rich stars with [N/Fe] ~ 0.8 observed in some GCs (e.g., NGC 6752). We discuss this apparent failure in the context of massive star formation preceding low-mass one within GC-forming GMCs (``bimodal star formation scenario''). We also show that although almost all stars (~97%) show normal He abundances (Y) of ~0.24 some stars later formed in GMCs can have Y as high as ~0.3 in some models. The number fraction of He-rich stars with Y >0.26 is however found to be small (~10^-3) for most models.

Dynamical Origin for Winner-Take-All Competition in A Biological Network of The Hippocampal Dentate Gyrus

description: We consider a biological network of the hippocampal dentate gyrus (DG). The DG is a pre-processor for pattern separation which facilitates pattern storage and retrieval in the CA3 area of the hippocampus. The main encoding cells in the DG are the granule cells (GCs) which receive the input from the entorhinal cortex (EC) and send their output to the CA3. The activation degree of GCs is so low (~ 5%). This sparsity has been thought to enhance the pattern separation. We investigate the dynamical origin for winner-take-all (WTA) competition which leads to sparse activation of the GCs. The whole GCs are grouped into lamellar clusters. In each GC cluster, there is one inhibitory (I) basket cell (BC) along with excitatory (E) GCs. There are three kinds of external inputs into the GCs; the direct excitatory EC input, the indirect inhibitory EC input, mediated by the HIPP (hilar perforant path-associated) cells, and the excitatory input from the hilar mossy cells (MCs). The firing activities of the GCs are determined via competition between the external E and I inputs. The E-I conductance ratio ${\cal{R}}_{\rm E-I}^{\rm (con)*}$ (given by the time average of the external E to I conductances) may represents well the degree of such external E-I input competition. GCs become active when their $\cal{R}_{\rm E-I}^{\rm (con)*}$ is larger than a threshold ${\cal{R}}_{th}^*$, and then the mean firing rates of the active GCs are strongly correlated with $\cal{R}_{\rm E-I}^{\rm (con)*}$. In each GC cluster, the feedback inhibition of the BC may select the winner GCs. GCs with larger $\cal{R}_{\rm E-I}^{\rm (con)*}$ than the threshold ${\cal{R}}_{th}^*$ survive, and they become winners; all the other GCs with smaller $\cal{R}_{\rm E-I}^{\rm (con)*}$ become silent. The WTA competition occurs via competition between the firing activity of the GCs and the feedback inhibition from the BC in each GC cluster.

description: We used the CSO 10.4 meter telescope to image the 350 micron and 450 micron continuum and CO J=6-5 line emission of the IRAS 20126+4104 clump. The continuum and line observations show that the clump is isolated over a 4 pc region and has a radius of ~ 0.5 pc. Our analysis shows that the clump has a radial density profile propto r ^{-1.2} for r ~ 0.1 pc which suggests the inner region is infalling, while the infall wave has not yet reached the outer region. Assuming temperature gradient of r^{-0.35}, the power law indices become propto r ^{-0.9} for r < ~0.1 pc and propto r^{-2.0} for r >~ 0.1 pc. Based on a map of the flux ratio of 350micron/450micron, we identify three distinct regions: a bipolar feature that coincides with the large scale CO bipolar outflow; a cocoon-like region that encases the bipolar feature and has a warm surface; and a cold layer outside of the cocoon region. The complex patterns of the flux ratio map indicates that the clump is no longer uniform in terms of temperature as well as dust properties. The CO emission near the systemic velocity traces the dense clump and the outer layer of the clump shows narrow line widths (< ~3 km/s). The clump has a velocity gradient of ~ 2 km/s pc^{-1}, which we interpret as due to rotation of the clump, as the equilibrium mass (~ 200 Msun) is comparable to the LTE mass obtained from the CO line. Over a scale of ~ 1 pc, the clump rotates in the opposite sense with respect to the >~ 0.03 pc disk associated with the (proto)star. This is one of four objects in high-mass and low-mass star forming regions for which a discrepancy between the rotation sense of the envelope and the core has been found, suggesting that such a complex kinematics may not be unusual in star forming regions.

title: Fine Structural Aspects of the Developing Eye of the Honey Bee
Creators: name: Eisen, Judith Susan
Publisher: name: Utah State University
Year: 1977

description: The post-embryonic development of the compound eye of the worker honey bee was investigated with the light and electron microscopes. The cells of the optic primordium were reorganized into preommatidial cell clusters during the late third and early fourth larval instars. Each cluster contained nine prospective retinula cells, the ninth was centrally located and shorter than the other eight; four prospective cone cells; and an undetennined number of prospective pigment cells.
Rhabdomere development began in the eight peripherally located retinula cells just prior to pupation. Following pupation, each ommatidium elongated. During ommatidial elongation, the short ninth retinula cell moved from its central location to a peripheral location within the ommatidium and also developed a rhabdomere. The shape of each prospective crystalline cone also changed from teardrop-shaped to spherical to the typical cone shape of the adult during differentiation.
The involvement of junctional specializations of membranes and of microtubules in the processes of differentiation, including elongation, cellular migration, and cellular organization, have been raised. Also, the role of multivesicular bodies in the process of lens formation has been discussed.

title: Xanthium strumarium L.: Extraction and Assay of Floral Promotive Principles and Additional Investigations into Inhibition of Flowering
Creators: name: Gibby, David D.
Publisher: name: Utah State University
Year: 1972

description: New techniques in extraction and assay of florigenic substances were tested. Initial response to the buffer-PVP extracts proved promising, but after several successful experiments, results could not be duplicated. Possible reasons for the failure are discussed.
A long-day inhibitory effect, demonstrated earlier by Gibby and Salisbury (25), was further investigated. Experiments with 14C-labled assimilates disproved the hypothesis that the inhibition is a result of assimilate translocation. Other experiments pointed to the probability of phytochrome involvement as well as protein synthesis as part of the inhibitory process. The nature of inhibition was ascribed to a localized inhibitory condition, probably a relatively immobile substance.

description: Two-dimensional electron gases (2DEGs) on the SrTiO3 (STO) surface or in STO-based heterostructures have exhibited many intriguing phenomena, which are strongly dependent on the 2DEG-carrier density. We report that the tunability of the 2DEG-carrier density is significantly enhanced by adding a monolayer LaTiO3 (LTO) onto the STO. Ultraviolet (UV) irradiation induced maximum carrier density of the 2DEG in LTO/STO is increased by a factor of ~4 times, compared to that of the bare STO. By oxygen gas exposure, it becomes 10 times smaller than that of the bare STO. This enhanced tunability is attributed to the drastic surface property change of a polar LTO layer by UV irradiation and O2 exposure. This indicates that the 2DEG controllability in LTO/STO is more reliable than that on the bare STO driven by defects, such an oxygen vacancy.

description: Pulsating ultra-luminous X-ray sources (PULXs) are characterised by an extremely large luminosity ($ > 10^{40} \text{erg s}^{-1}$). While there is a general consensus that they host an accreting, magnetized neutron star (NS), the problem of how to produce luminosities $> 100$ times the Eddington limit, $L_E$, of a solar mass object is still debated. A promising explanation relies on the reduction of the opacities in the presence of a strong magnetic field, which allows for the local flux to be much larger than the Eddington flux. However, avoiding the onset of the propeller effect may be a serious problem. Here, we reconsider the problem of column accretion onto a highly magnetized NS, extending previously published calculations by relaxing the assumption of a pure dipolar field and allowing for more complex magnetic field topologies. We find that the maximum luminosity is determined primarily by the magnetic field strength near the NS surface. We also investigate other factors determining the accretion column geometry and the emergent luminosity, such as the assumptions on the parameters governing the accretion flow at the disk-magnetosphere boundary. We conclude that a strongly magnetized NS with a dipole component of $\sim 10^{13} \text{G}$, octupole component of $\sim10^{14} \text{G}$ and spin period $\sim1 \text{s}$ can produce a luminosity of $\sim 10^{41} \text{erg s}^{-1}$ while avoiding the propeller regime. We apply our model to two PULXs, NGC 5907 ULX-1 and NGC 7793 P13, and discuss how their luminosity and spin period rate can be explained in terms of different configurations, either with or without multipolar magnetic components.

description: We studied synchronization between prisoner's dilemma games with voluntary participation in two Newman-Watts small-world networks. It was found that there are three kinds of synchronization: partial phase synchronization, total phase synchronization and complete synchronization, for varied coupling factors. Besides, two games can reach complete synchronization for the large enough coupling factor. We also discussed the effect of coupling factor on the amplitude of oscillation of $cooperator$ density.

description: Der Beitrag lotet das Verhältnis von ambigen und politischen Aussagen in Raptexten aus. Die Nähe der Ambiguität zum politischen Sprechen wird historisch und systematisch rekonstruiert. Diese Nähe ist Motivation für unterschiedliche Wertungshandlungen in der Rap-Rezeption, eine spielerisch-subversive Tendenz emphatisch als ›politisch‹, eine eindeutig-subversive Tendenz kritisch als ›gefährlich‹ zu klassifizieren. Eine Analyse solcher Wertungen und der ambiguierenden Strategien des Rappers Kollegah geht den rhetorischen und visuellen Transformationen von der Hoodtales-Serie bis zu den Endzeitszenarien Armageddon und Apokalypse nach und diskutiert die Zusammenhänge von Mehrdeutigkeit, politischem Pop und erinnerungspolitischen Tabus.

description: Unintended effects of gene edit crops may pose safety issues. Omics is a useful tool for researchers to evaluate these unexpected effects. Transcriptome and proteomics analyses were performed for two gene editors, CRISPR-Cas9 and adenine base editor (ABE) gene edit rice, as well as corresponding wild-type plants (Nipponbare). Transcriptome revealed 520 and 566 rice differentially expressed genes (DEGs) in the Cas9/Nip and ABE/Nip comparisons, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that most DEGs participated in metabolism of terpenoids and polyketones, plant–pathogen interactions, and plant signal transduction. It mainly belongs to environmental adaptation. Proteomics revealed 298 and 54 rice differentially expressed proteins (DEPs) in the Cas9/Nip and ABE/Nip comparisons, respectively. KEGG pathway enrichment analysis showed that most DEPs participated in the biosynthesis of secondary metabolite and metabolic pathways. According to integrated transcriptomes and proteomics analysis, the results showed that no newly generated genes were identified as new transcripts of these differentially expressed genes, and gene edit tools had little effect on rice transcription levels and no new proteins were generated in the gene-edited rice.

description: Over the last 15 years, around a hundred very young stars have been observed in the central parsec of our Galaxy. While the presence of young stars forming one or two stellar disks at approx. 0.1 pc from the supermassive black hole (SMBH) can be understood through star formation in accretion disks, the origin of the S stars observed a factor of 10 closer to the SMBH has remained a major puzzle. Here we show the S stars to be a natural consequence of dynamical interaction of two stellar disks at larger radii. Due to precession and Kozai interaction, individual stars achieve extremely high eccentricities at random orientation. Stellar binaries on such eccentric orbits are disrupted due to close passages near the SMBH, leaving behind a single S star on a much tighter orbit. The remaining star may be ejected from the vicinity of the SMBH, thus simultaneously providing an explanation for the observed hypervelocity stars in the Milky Way halo.

description: Durch das neuste Album von K.I.Z Rap über Hass (2021) wird nicht nur innerhalb des HipHops vermehrt über Hass im Rap diskutiert, sondern auch in den Feuilletonteilen überregionaler deutschsprachiger Zeitungen. Dabei stellt sich die Frage, ob dieser Hass neu ist und welche Funktion er einnimmt. Und ist das, was im Rap als Hass bezeichnet und produktiv gemacht wird, überhaupt Hass oder viel eher Wut? Um diesen Fragen nachzugehen, wird untersucht, woher der Rap stammt, wieso dieser genuin politisch ist und welcher Zusammenhang zwischen dem Rap, dem Politischen und dem Hass überhaupt besteht. Anhand einiger deutschsprachiger Rap-Songs wird dargestellt, dass Hass als existenzielles Gefühl unter anderem eine grenzüberschreitende Wirkung hat und damit beispielsweise affirmativ, zur Lenkung von Aufmerksamkeit und zur Abgrenzung genutzt werden kann.
