description: Proton decay is a smoking gun signature of Grand Unified Theories (GUTs). Searches by Super-Kamiokande have resulted in stringent limits on the GUT symmetry breaking scale. The large-scale multipurpose neutrino experiments DUNE, Hyper-Kamiokande and JUNO will either discover proton decay or further push the symmetry breaking scale above $10^{16}$ GeV. Another possible observational consequence of GUTs is the formation of a cosmic string network produced during the breaking of the GUT to the Standard Model gauge group. The evolution of such a string network in the expanding Universe produces a stochastic background of gravitational waves which will be tested by a number of gravitational wave detectors over a wide frequency range. We demonstrate the non-trivial complementarity between the observation of proton decay and gravitational waves produced from cosmic strings in determining $SO(10)$ GUT breaking chains. We show that such observations could exclude $SO(10)$ breaking via flipped $SU(5)\times U(1)$ or standard $SU(5)$, while breaking via a Pati-Salam intermediate symmetry, or standard $SU(5)\times U(1)$, may be favoured if a large separation of energy scales associated with proton decay and cosmic strings is indicated. We note that recent results by the NANOGrav experiment have been interpreted as evidence for cosmic strings at a scale $\sim 10^{14}$ GeV. This would strongly point towards the existence of GUTs, with $SO(10)$ being the prime candidate. We show that the combination with already available constraints from proton decay allows to identify preferred symmetry breaking routes to the Standard Model.

description: In this sturdy, we determine the roles of two successive phase transitions in the new spin-Peierls system TiOBr by electron and synchrotron X-ray diffraction analyses. Results show an incommensurate superstructure along the h- and k-directions between Tc1=27K and Tc2=47K, and a twofold superstructure which is related to a spin-Peierls lattice distortion below Tc1. The diffuse scattering observed above Tc2 indicates that a structural correlation develops at a high temperature. We conclude that Tc2 is a second-order lock-in temperature, which is related to the spin-Peierls lattice distortion with the incommensurate structure, and that Tc1 is from incommensurate to commensurate phase transition temperature accompanying the first-order spin-Peierls lattice distortion.

The bound nucleon form factors of the vector and axial-vector currents are calculated in the quark-meson coupling model. We compute the inclusive $^{12}$C($ν_μ,μ^-$)$X$ cross sections using a relativistic Fermi gas model with the calculated bound nucleon form factors. The effect of the bound nucleon form factors for this reaction is a reduction of $\sim$8% for the total cross section, relative to that calculated with the free nucleon form factors.

description: We investigate the influence of light-matter interactions on correlated quantum matter by studying the paradigmatic Ising model subject to a quantum Rabi coupling. This type of coupling to a confined, spatially delocalized bosonic light mode, such as provided by an optical resonator, resembles a quantized transverse magnetic field of tunable strength. As a consequence, the symmetry-broken magnetic state breaks down for strong enough light-mater interactions to a paramagnetic state. The non-local character of the bosonic mode can change the quantum phase transition in a drastic manner, which we analyze quantitatively for the simplest case of a chain geometry (Dicke-Ising chain). The results show a direct transition between a magnetically ordered phase with zero photon density and a magnetically polarized phase with lasing behaviour of the light. Our predictions are equally valid for the dual quantized Ising chain in a conventional transverse magnetic field.

description: There are many instances where individual marker genes are of value in breeding programs or genetic studies, or where multiple markers are useful even if their relative positions on a linkage map are not known. In these cases, isozyme markers are of value because they can be detected relatively easily and inexpensively, as well as at an early stage of plant development. Most isozyme polymorphisms have been shown to have a simple genetic basis. Allozymes, the isozyme bands that denote allelic polymorphism at a single locus, display codominant expression, so that plants heterozygous at an isozyme locus may be distinguished from either homozygote. These qualities of isozymes make them useful for the confirmation of hybridity and other forms of pedigree analysis. Isozymes have also been used to tag genes of agricultural importance. Examples of these uses of isozymes will be presented.

We show the first results for ESO 400-G43 based on deep VLT/FORS2 spectroscopy. The instabilities found in the central gaseous velocity field are not seen in the solid body stellar rotation curve, indicating that stars and gas are kinematically decoupled in this galaxy. Even if this galaxy has a perturbed gaseous velocity field, the stellar velocity dispersion on average agrees well with that derived from the nebular lines.

Publisher: name: FID GEO

description: Decay of trachyte used as building stone in urban environment was investigated through the analysis of crusts and patinas found on trachyte of the Euganean Hills in the Renaissance city walls of Padua, northeastern Italy. Mineralogical and microstructural characteristics of the alteration products, as well as major- and trace-element chemical composition, were determined by optical microscopy, SEM–EDS and X-ray mapping, XRPD, and LA-ICPMS. The results are discussed referring to environmental parameters, in particular concerning air quality and anthropic pollution sources. The influence of composition of the stone and other neighboring materials on specific weathering processes is also debated. The formation of crusts and patinas turns out to be mainly due to exogenous processes. Enrichment in heavy metals and carbonaceous matter derives from the deposition of particulate emitted during fuel combustion by road vehicles, domestic heating and, secondarily, industrial activities. The particulate is typically cemented by calcite, mainly mobilized after dissolution from nearby mortar joints, or iron, released by leaching from iron-bearing minerals, reprecipitated according to pH fluctuations. Gypsum layers were rarely observed. Generally, composition of the weathering crusts and patinas of Euganean trachyte proves to be an informative marker for the relevant environmental conditions and their evolution.

description: We study numerically the distribution of scattering phases ${\cal P}(Φ)$ and of Wigner delay times ${\cal P}(τ_W)$ for the power-law banded random matrix (PBRM) model at criticality with one channel attached to it. We find that ${\cal P}(Φ)$ is insensitive to the position of the channel and undergoes a transition towards uniformity as the bandwidth $b$ of the PBRM model increases. The inverse moments of Wigner delay times scale as $\sim L^{- q D_{q+1}}$, where $D_q$ are the multifractal dimensions of the eigenfunctions of the corresponding closed system and $L$ is the system size. The latter scaling law is sensitive to the position of the channel.

description: This research explores the lived experiences of junior and senior undergraduate student subjects from the FGLID (First-Generation, Low-Income, and/or Disabled) community facing significant barriers in the realm of higher education. The challenges contribute to the broadening of the educational gap, observable in lower graduation and persistence rates compared to non-FGLID peers (Jeong et al., 2023; Longwell-Grice et al., 2016; Mikell & Davis, 2022). The study follows a descriptive qualitative research design and provides insights into the lived experience of FGLID participants through a semi-structured interview process. This study employed a strength-based approach (Weick et al., 1989) and was guided by Chickering and Reisser's (1993) theory of student development which focuses on the seven vectors of identity development as well as the impact of environmental influences. Results generated 26 codes, with the top nine most prominent emerging as significant in theme generation. Participants' contributions revealed three central themes in understanding the lived experience of FGLID students and factors contributing to their ability to persist: (1) the state of social capital, (2) the existence of a resource framework, and (3) the process of identity formulation. These themes, while affirming aspects of Chickering and Reisser's (1993) framework, also highlighted areas where further exploration is needed such as deeper exploration into the sub-demographics of the FGLID population, exploring the impact of the physical environment, and seeking to understand the correlation of the grief processes in the development of identity and one's ability to navigate challenges.

description: Genetic engineering techniques currently permit several approaches to produce crop plants with enhanced resistance to pests. Many groups are directly introducing genes which encode for pest resistance into the plant's genome. Crop Genetics International is developing an endophyte based technology for systemic delivery of biopesticides to corn and other crops. Defined broadly, an endophyte is a plant dependent microorganism that lives protected within the tissues of its host. Among endophytic bacteria, those associated with plant disease have been the past object of study. However, nonpathogenic bacterial endophytes present an opportunity for systemic delivery of genetically-engineered biopesticides and plant growth regulators. Crop Genetics has chosen a xylem-limited endophytic bacterium, Clavibacter xyli subsp. cvnodontis (Cxc) which occurs naturally in bermudagrass and is distributed throughout the southern two-thirds of the U.S. as well as Europe and Asia. Cxc is a fastidious microorganism with precise nutritional and environmental requirements. Cxc survival is brief outside the host plant in plant debris, soil, air or water, and the endophyte is not seed transmitted. Cxc, when modified with recombinant DNA techniques, provides a systemic delivery system for biopesticides within plants. The first product under development involves Cxc producing the delta-endotoxin of Bacillus thurinqiensis toxic to European corn borer (Ostrina nubilalis). Follow-on products will deliver other insecticides, fungicides, and plant growth enhancers. Crop Genetics has developed an inoculation technology to introduce the bacterium into seeds. The protocol includes imbibition followed by pressure treatment in a buffered solution containing the bacterium. Seeds are removed from the solution, dried, and coated with conventional seed coatings. This inoculation technology does not alter seed vigor or germination and provides a satisfactory shelf life of the product.
A Bayesian Hierarchical Score for Structure Learning from Related Data Sets

description: Score functions for learning the structure of Bayesian networks in the literature assume that data are a homogeneous set of observations; whereas it is often the case that they comprise different related, but not homogeneous, data sets collected in different ways. In this paper we propose a new Bayesian Dirichlet score, which we call Bayesian Hierarchical Dirichlet (BHD). The proposed score is based on a hierarchical model that pools information across data sets to learn a single encompassing network structure, while taking into account the differences in their probabilistic structures. We derive a closed-form expression for BHD using a variational approximation of the marginal likelihood, we study the associated computational cost and we evaluate its performance using simulated data. We find that, when data comprise multiple related data sets, BHD outperforms the Bayesian Dirichlet equivalent uniform (BDeu) score in terms of reconstruction accuracy as measured by the Structural Hamming distance, and that it is as accurate as BDeu when data are homogeneous. This improvement is particularly clear when either the number of variables in the network or the number of observations is large. Moreover, the estimated networks are sparser and therefore more interpretable than those obtained with BDeu thanks to a lower number of false positive arcs.

description: Cacao molecular biology research at Penn State University is directed at six areas: 1) regenerating trees from tissue culture, 2) genetically transforming the tree, 3) cloning lipid biosynthetic genes, 4) characterizing the genomes, 5) isolating genes that may confer fungal disease resistance, and 6) creating an RFLP linkage map. An accomplishment with tissue culture studies is developing a method to readily induce "break" in excised lateral buds. These results will lead to the rapid propagation of selected cultivars. Because a long-term goal is to engineer the tree for a hard cocoa butter regardless of the climate, we have cloned a putative glycerol-3-phosphate acyltransferase gene, the first one in the cocoa butter biosynthetic pathway. Another project is to eventually engineer cacao to be more resistant to fungal diseases; thus cocoa genomic library is being screened for the gene encoding beta-1,3-glucanase, a hydrolase which degrades fungal cell walls. To more thoroughly understand the molecular biology of cacao, the nuclear genome is being characterized. Preliminary evidence suggests the cacao nuclear genome is smaller than that of most higher plants. Finally, efforts have begun to genetically transform the tree, and to develop a map of the cacao genome based on RFLPs.
THE ABC'S OF PLANT RFLPs

description: Traditionally, plant geneticists and plant breeders relied on easily recognizable phenotypic differences, such as flower color, in their studies. More recently, isozyme marker systems, which distinguish among different forms of enzymes, have increased the number of readily scoreable phenotypes. With the advent of restriction fragment length polymorphism (RFLP) markers, it is now possible to detect differences in DNA sequences that do not necessarily result in phenotypic differences. This is because RFLP markers are different among homologous DNA fragment lengths that result from base pair changes in the restriction enzyme recognition sites between genotypes. RFLP markers can be observed after the restriction fragments have been separated by agarose gel electrophoresis, Southern blotted, and hybridized with a radioactively labeled DNA probe which is homologous to these fragments (locus). Therefore, RFLPs serve as genetic markers.

description: We reanalyse the potential of the LHC to discover new $Z'$ gauge bosons and to discriminate between various theoretical models. Using a fast LHC detector simulation, we have investigated how well the characteristics of $Z'$ bosons from different models can be measured. For this analysis we have combined the information coming from the cross section measurement, which provides also the $Z'$ mass and total width, the forward-backward charge asymmetries on- and off-peak, and the $Z'$ rapidity distribution, which is sensitive to its $u \bar{u}$ and $d \bar{d}$ couplings. We confirm that new $Z'$ bosons can be observed in the process $pp \to Z' \to l^+ l^-$, up to masses of about 5 TeV for an integrated luminosity of 100 fb$^{-1}$. The off- and on-resonance peak forward-backward charge asymmetries $A_{\rm FB}^{l}$ show that interesting statistical accuracies can be obtained up to $Z'$ masses of the order of 2 TeV. We then show how the different experimental observables allow for a diagnosis of the $Z'$ boson and the distinction between the various considered models.

In both filters five point-like sources are detected, of which at least one has a spectral energy distribution reminiscent of a Lada Class I source. We also report on the discovery of a new Herbig Ae star in this region. It is particularly striking that the brightest mid-infrared source in this region has not been detected at shorter wavelengths; it is a good candidate to be the driving source of the bipolar molecular outflow and optical reflection nebulosity previously reported in S287B.

description: The potential of micropropagation as a means to control disease and to accelerate germplasm buildup has been demonstrated for many different kinds of vegetatively propagated plants, including the aroid root crops, Colocasia and Xanthosoma. However, because of labor costs and the necessity of expensive facilities, the direct commercial application of this technology has been limited to those plants, such as the foliage aroid Dieffenbachia. with relatively high cash values per propagating unit. Based upon computer models using industrygenerated data, we have determined that cost efficiencies are already near their theoretical optima for micropropagation using adventitious and axillary shoot proliferation technologies. Accordingly, alternative means must be deployed for commercial production of aroid root crops and other relatively low cash value aroids, such as Caladium. Robotics and synthetic seed technologies offer promise, but are still early in the developmental stage. Currently, the financial benefits of root crop micropropagation can only be realized when plants derived from this technology are field-grown and multiplied by conventional methods to numbers large enough to drop the cost per propagating unit to commercially acceptable levels. In instances where disease control is a primary objective, it may be necessary to establish blocks of mother plants isolated from major sources of inoculum.
Positive- and negative-frequency noise from an ensemble of two-level fluctuators

description: The analysis of charge noise based on the Bloch-Redfield treatment of an ensemble of dissipative two-level fluctuators generally results in a violation of the fluctuation-dissipation theorem. The standard Markov approximation (when applied to the two-level fluctuators coupled to a bath) can be identified as the main origin of this failure. The resulting decoherence rates only involve the bath response at the fluctuator frequency, and thus completely neglect the effects of frequency broadening. A systematic and computationally convenient way to overcome this issue is to employ the spectator-qubit method: by coupling an auxiliary qubit to the two-level fluctuator ensemble, an analytical approximation for $S(ω)$ fully consistent with the fluctuation-dissipation theorem can be obtained. We discuss the resulting characteristics of the noise which exhibits distinct behavior over several frequency ranges, including a $1/f$ to $1/f^2$ crossover with a $T^3$ temperature dependence of the crossover frequency.

Atmospheric CO2 fertilization effects on biomass yields of 10 crops in northern Germany
Creators: name: Degener, Jan F.
Publisher: name: FID GEO
Year: 2015

description: The quality and quantity of the influence that atmospheric CO2 has on crop growth is still a matter of debate. This study's aim is to estimate if [CO2] will have an effect on biomass yields at all, to quantify and spatially locate the effects and to explore if an elevated photosynthesis rate or water-use-efficiency is predominantly responsible. This study uses a numerical carbon-based crop model (BioSTAR) to estimate biomass yields within the administrative boundaries of Niedersachsen in Northern Germany. Ten crops are included (winter grains: wheat, barley, rye, triticale—early, medium, late maize variety—sunflower, sorghum, spring wheat), modeled annually for the entire twenty-first century on 91,014 separate sites. Modeling was conducted twice, once with an annually adapted [CO2] concentration according to the SRES-A1B scenario and once with a fixed concentration of 390 ppm to separate the influence of [CO2] from that of the other input variables. Rising [CO2] concentrations will play a central role in keeping future yields of all crops above or around today's level. Differences in yields between modeling with fixed or adapted [CO2] can be as high as 60% toward the century's end. Generally, yields will increase when [CO2] rises and decline when it is kept constant. As C4-crops are equivalently affected it is presumed that an elevated efficiency in water use is the main responsible factor for all plants.

description: La evaluación de desempeño, sin lugar a dudas, es considerada como una herramienta esencial para evaluar y medir la contribución de los empleados dentro de la organización. No obstante, la evaluación tradicional aún se encuentra centrada en asignar calificaciones numéricas por lo que ha puesto de manifiesto sus limitaciones al ser percibida como subjetiva y, en ocasiones, incapaz de captar de manera precisa y equitativa el verdadero rendimiento de los trabajadores. En este contexto, este articulo tiene como objetivo adentrarse en la necesidad imperante de trascender la limitada perspectiva de la calificación numérica y, en su lugar, adoptar un enfoque más integral y holístico en la evaluación de desempeño. Este cambio de paradigma busca no solo corregir las deficiencias observadas en las evaluaciones convencionales, sino también potenciar el desarrollo y la motivación de los empleados mediante la adopción de métodos más precisos y significativos ya que en lugar de depender exclusivamente de cifras aisladas, un enfoque holístico de evaluación de desempeño considera una variedad de factores.

description: Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different areas, Rabbit Ears Pass near Steamboat Springs and at Fraser Experimental Forest near Fraser, Colorado USA. Differences between no use and varying degrees of snowmobile use (low, medium and high) on shallow (the operational standard of 30 cm) and deeper snowpacks (120 cm) were quantified and statistically assessed using measurements of snow density, temperature, stratigraphy, hardness, and ram resistance from snow pit profiles. A simple model was explored that estimated snow density changes from snowmobile use based on experimental results. Snowpack property changes were more pronounced for thinner snow accumulations. When snowmobile use started in deeper snow conditions, there was less difference in density, hardness, and ram resistance compared to the control case of no snowmobile use. These results have implications for the management of snowmobile use in times and places of shallower snow conditions where underlying natural resources could be affected by denser and harder snowpacks.

description: At nonzero temperatures, superconductors contain excitations known as Bogoliubov quasiparticles. The mesoscopic dynamics of quasiparticles inform the design of quantum information processors, among other devices. Knowledge of these dynamics stems from experiments in which quasiparticles are injected in a controlled fashion, typically at energies comparable to the pairing energy . Here we perform tunnel spectroscopy of a mesoscopic superconductor under high electric field. We observe quasiparticle injection due to field-emitted electrons with 10^6 times the pairing energy, an unexplored regime of quasiparticle dynamics. Upon application of a gate voltage, the quasiparticle injection decreases the critical current and, at sufficiently high electric field, the field-emission current (< 0.1 nA) switches the mesoscopic superconductor into the normal state, consistent with earlier results. We expect that high-energy injection will be useful for developing quasiparticle-tolerant quantum information processors, will allow rapid control of resonator quality factors, and will enable the design of electric-field-controlled superconducting devices with new functionality.

 Morphological characters
 The newly trapped specimens display the typical Otomys laminated tooth pattern. The females have 0 + 1 mammae. On the molars we observe the presence of five laminae on M/1, the deeply grooved incisors (one striation 1/1) and a 7-8 laminae pattern in the upper M3. But, based on their morphology and external measurements (Table 6), we assigned the new samples to the endemic O. occidentalis species. This was confirmed in a molecular and morphometrical revision of the 5 laminae species complex (Taylor et al. 2014).

Searching for the Intra-Group Medium in Loose Groups of Galaxies

description: We have conducted a study with the VLA, DRAO Synthesis Telscope, and the FUSE satellite to search for the intra-group medium in two loose groups of galaxies: GH 144 and GH 158. No HI was detected near the background AGN in GH 158, however two previously unknown dwarf galaxies were detected in GH 144. Lyman-alpha, -beta, CIII and NV absorption was detected in GH 144 by FUSE. Using this data and previously published data we found that the virial mass of GH 144 is 2x10^12 M(sun). Of this 8% lies in the individual group galaxies, and less than 8% is in the dense neutral intra-group medium. From our absorption line data we constrain the diffuse IGM to have a volume density greater than log n = -5.2 in a layer less than 22 kpc thick assuming a metallicity of 0.4 solar. While these values are uncertain, it is unlikely that this diffuse gas contributes a significant fraction of the group mass. Given the depth of the absorbing material and its separation from the nearest galaxies, it seems most likely it originates from a small-clump in the IGM, perhaps an ionized high-velocity cloud.

Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia

description: The crater lake of the small volcanic island Satonda, Indonesia, is unique for its red-algal microbial reefs thriving in marinederived water of increased alkalinity. The lake is a potential analogue for ancient oceans sustaining microbialites under open-marine conditions. Current reef surfaces are dominated by living red algae covered by non-calcified biofilms with scattered cyanobacteria and diatoms. Minor CaCO3 precipitates are restricted to the seasonally flooded reef tops, which develop biofilms up to 500 mm thick dominated by the cyanobacteria Pleurocapsa, Calothrix, Phormidium, and Hyella. Microcrystalline aragonite patches form within the biofilm mucilage, and fibrous aragonite cements grow in exopolymer-poor spaces such as the inside of dead, lysed green algal cells, and reef framework voids. Cementation of lysed hadromerid sponge resting bodies results in the formation of ‘‘Wetheredella-like’’ structures. Hydrochemistry data and model calculations indicate that CO2 degassing after seasonal mixis can shift the carbonate equilibrium to cause CaCO3 precipitation. Increased concentrations of dissolved inorganic carbon limit the ability of autotrophic biofilm microorganisms to shift the carbonate equilibrium. Therefore, photosynthesis-induced cyanobacterial calcification does not occur. Instead, passive, diffusioncontrolled EPS-mediated permineralization of biofilm mucus at contact with the considerably supersaturated open lake water takes place. In contrast to extreme soda lakes, the release of Ca21 from aerobic degradation of extracellular polymeric substances does not support CaCO3 precipitation in Satonda because the simultaneously released CO2 is insufficiently buffered. Subfossil reef parts comprise green algal tufts encrusted by microstromatolites with layers of fibrous aragonite and an amorphous, unidentified Mg–Si phase. The microstromatolites probably formed when Lake Satonda evolved from seawater to Ca21-depleted raised-alkalinity conditions because of sulfate reduction in bottom sediments and pronounced seasonality with deep mixing events and strong CO2 degassing. The latter effect caused rapid growth of fibrous aragonite, while Mg–Si layers replaced the initially Mg-calcite-impregnated biofilms. This could be explained by dissolution of siliceous diatoms and sponge spicules at high pH, followed by Mg-calcite dissolution and Mg-silica precipitation at low pH due to heterotrophic activity within the entombed biofilms.

description: Over the last 5 years rapid advantages have been made both in terms of transformation technology, using both Agrobacterium rhizogenes and Agrobacterium tumefaciens. Also new methods have been found for foreign gene introduction. Coupled to this rapid advance has been the availability of a wide range of genes that can be introduced. Among the genes that are currently available are genes to confer resistance to viruses, bacteria, fungi and insects. These genes are of various degrees of effectiveness and much depends on the type of promotors used in conjunction with the gene. CIP (The International Potato Center) has developed a network of collaborating institutions that work on varying aspects of these pest and disease resistances. In this presentation data is given on the analysis of various transformations for bacterial disease resistance. The genes used to confer this bacterial resistance code for lytic proteins and are isolated from silk moths. Discussions will be oriented towards the advantages and disadvantages of this type of approach over conventional breeding.

description: The USDA regulation of organisms and products developed through biotechnology is, in general, related to the Department's mandate from the U.S. Congress to protect the nation's plant and animal health. Under the authority granted by the Federal Plant Pest Act and the Plant Quarantine Act, the USDA regulates the movement into and through the United States of plants, plant products, plant pests and any product or article which may contain a plant pest at the time of movement. Under this broad authority, the USDA regulates a number of potential food products of biotechnology and products used in food animals, inclu'ding: 1) transgenic plants and microorganisms; 2) veterinary biological products developed through biotechnology. 3) animals used in biotechnology research. The Federal policy statement on biotechnology regulation that was published in final form in June 1986 contains several main elements: 1) the products of recombinant DNA technology will not differ fundamentally from unmodified organisms or from conventional products; 2) the existing laws are adequate for regulating organisms and products developed by the new processes; 3) the product and the risk should be regulated, not the process and 4) regulation should be based on the end use of the product and conducted on a case-by-case baseis. The USDA policy has been consistent with the overall Federal policy and National Academy of Sciences recommendations. The USDA Agency directly concerned is the Animal and Plant Health Inspection Service (APHIS) which has combined a number of existing staffs to create the Biotechnology, Biologies, and Environmental Protection Division.
