description: In this paper we provide a comprehensive description of the internal dynamics of G0.253+0.016 (a.k.a. 'the Brick'); one of the most massive and dense molecular clouds in the Galaxy to lack signatures of widespread star formation. As a potential host to a future generation of high-mass stars, understanding largely quiescent molecular clouds like G0.253+0.016 is of critical importance. In this paper, we reanalyse Atacama Large Millimeter Array cycle 0 HNCO $J=4(0,4)-3(0,3)$ data at 3 mm, using two new pieces of software which we make available to the community. First, scousepy, a Python implementation of the spectral line fitting algorithm scouse. Secondly, acorns (Agglomerative Clustering for ORganising Nested Structures), a hierarchical n-dimensional clustering algorithm designed for use with discrete spectroscopic data. Together, these tools provide an unbiased measurement of the line of sight velocity dispersion in this cloud, $σ_{v_{los}, {\rm 1D}}=4.4\pm2.1$ kms$^{-1}$, which is somewhat larger than predicted by velocity dispersion-size relations for the Central Molecular Zone (CMZ). The dispersion of centroid velocities in the plane of the sky are comparable, yielding $σ_{v_{los}, {\rm 1D}}/σ_{v_{pos}, {\rm 1D}}\sim1.2\pm0.3$. This isotropy may indicate that the line-of-sight extent of the cloud is approximately equivalent to that in the plane of the sky. Combining our kinematic decomposition with radiative transfer modelling we conclude that G0.253+0.016 is not a single, coherent, and centrally-condensed molecular cloud; 'the Brick' is not a \emph{brick}. Instead, G0.253+0.016 is a dynamically complex and hierarchically-structured molecular cloud whose morphology is consistent with the influence of the orbital dynamics and shear in the CMZ.

description: The combination of the latest and most precise measurements of several top quark properties is presented in this paper in order to establish allowed regions on anomalous contributions to the Lorentz structure of the $Wtb$ vertex. These measurements include single top production cross sections, $W$ boson helicity fractions and forward-backward asymmetries, both at Tevatron and at the Large Hadron Collider, up to a center-of-mass energy of 13 TeV. The results obtained at 95% Confidence Level for the top quark anomalous couplings are compared with the limits extracted from a combination that includes the expected measurements at the future High-Luminosity run of the Large Hadron Collider.

description: Understanding the fate of planetary systems through white dwarfs which accrete debris crucially relies on tracing the orbital and physical properties of exo-asteroids during the giant branch phase of stellar evolution. Giant branch luminosities exceed the Sun's by over three orders of magnitude, leading to significantly enhanced Yarkovsky and YORP effects on minor planets. Here, we place bounds on Yarkovsky-induced differential migration between asteroids and planets during giant branch mass loss by modelling one exo-Neptune with inner and outer exo-Kuiper belts. In our bounding models, the asteroids move too quickly past the planet to be diverted from their eventual fate, which can range from: (i) populating the outer regions of systems out to 10^4-10^5 au, (ii) being engulfed within the host star, or (iii) experiencing Yarkovsky-induced orbital inclination flipping without any Yarkovsky-induced semimajor axis drift. In these violent limiting cases, temporary resonant trapping of asteroids with radii of under about 10 km by the planet is insignificant, and capture within the planet's Hill sphere requires fine-tuned dissipation. The wide variety of outcomes presented here demonstrates the need to employ sophisticated structure and radiative exo-asteroid models in future studies. Determining where metal-polluting asteroids reside around a white dwarf depends on understanding extreme Yarkovsky physics.

description: We investigate existence of replica off-diagonal solutions in the field-theoretical description of Sachdev-Ye-Kitaev model. To this end we evaluate a set of local and non-local dynamic correlation functions in the long time limit. We argue that the structure of the soft-mode Schwarzian action is qualitatively different in replica-diagonal vs. replica-off-diagonal scenarios, leading to distinct long-time predictions for the correlation functions. We then evaluate the corresponding correlation functions numerically and compare the simulations with analytical predictions of replica-diagonal and replica-off-diagonal calculations. We conclude that all our numerical results are in a quantitative agreement with the theory based on the replica-diagonal saddle point plus Schwarzian and massive Gaussian fluctuations (the latter do contain replica off-diagonal components). This seems to exclude any contributions from replica-off-diagonal saddle points, at least on the time scales shorter than the inverse many-body level spacing.

description: Athis flavimaculata (Miller, 1972) is a diurnal moth species distributed across Mexico. This study integrates recent field research and an extensive review of entomological collections to improve knowledge of the species’ geographic distribution, ecology, host plants, and previously undocumented bionomic and behavioural traits. The species is reported for the first time in the Mexican states of Colima and Oaxaca. Its status as endemic to the Pacific slope of Mexico is confirmed, while the record from Guatemala is rejected based on wing pattern and geometric morphometric analysis. Male and female wing variability is analysed and illustrated here for the first time. This work represents the first use of geometric morphometric analysis to study wing venation and sexual dimorphism in Castniidae.

description: We present a statistical study of 62 coronal dimming events associated with Earth-directed CMEs during the quasi-quadrature period of STEREO and SDO. This unique setting allows us to study both phenomena in great detail and compare characteristic quantities statistically. Coronal dimmings are observed on-disk by SDO/AIA and HMI, while the CME kinematics during the impulsive acceleration phase is studied close to the limb with STEREO/EUVI and COR, minimizing projection effects. The dimming area, its total unsigned magnetic flux and its total brightness, reflecting properties of the total dimming region at its final extent, show the highest correlations with the CME mass ($c\sim0.6-0.7$). Their corresponding time derivatives, describing the dynamics of the dimming evolution, show the strongest correlations with the CME peak velocity ($c\sim 0.6$). The highest correlation of $c=0.68\pm0.08$ is found with the mean intensity of dimmings, indicating that the lower the CME starts in the corona, the faster it propagates. No significant correlation between dimming parameters and the CME acceleration was found. However, for events where high-cadence STEREO observations were available, the mean unsigned magnetic field density in the dimming regions tends to be positively correlated with the CME peak acceleration ($c=0.42\pm0.20$). This suggests that stronger magnetic fields result in higher Lorentz forces providing stronger driving force for the CME acceleration. Specific coronal dimming parameters correlate with both, CME and flare quantities providing further evidence for the flare-CME feedback relationship. For events in which the CME occurs together with a flare, coronal dimmings statistically reflect the properties of both phenomena.

description: Lewis-acid-catalyzed reactions of 2-substituted cyclopropane 1,1-dicarboxylates with thioketones are described. Highly substituted tetrahydrothiophenes with two adjacent quaternary carbon atoms were obtained in a stereospecific manner under mild conditions and in high yield when using AlCl3 as Lewis acid. Moreover, an intramolecular approach was successfully implemented to gain access to sulfur-bridged [n.2.1] bicyclic ring systems. Conversion of selenoketones, the heavier analogues, under similar conditions resulted in the formation of various tetrahydroselenophenes.
Mulberry (Morus alba) leaf meal in indigenous chicken layer diets: effect on egg production and quality

description: Soybean meal is the main protein ingredient in poultry feeds. It is expensive, inadequate in supply and does not have sufficient β-carotene which gives the yellow yolk colour preferred by most consumers. Mulberry leaf meal (MLM) has been identified as a locally available alternative protein source in poultry feeds and contains β-carotene that may improve egg production and yolk colour. However, the optimal level of inclusion in layer diets is unknown and there is need for it to be determined. This study therefore determined the effects of inclusion of MLM as a protein source in indigenous chicken (IC) diets on feed intake, egg production and quality. Sixty, 29-week-old IC were used in this study. The Experimental diets contained 16% CP, calculated metabolizable energy of 2800kcal ME/KG and SBM was substituted by MLM at the following levels: 0% (Diet 1), 5% (Diet 2), 10% (Diet 3) and 15% (Diet 4). The chickens were offered the experimental diets for 8 weeks. Objective one determined the effects of inclusion of mulberry leaf meal in the diets on feed intake, feed conversion ratio (FCR), and egg laying percentage. Data on feed intake and egg production and FCR were collected daily. Feed conversion ratio data was calculated by dividing the weight of feed consumed by the weight of eggs produced. In objective two, a sample of five eggs per treatment were used to assess the external qualities (shape index, egg shell thickness and egg shell ratio). Objective three determined the internal egg qualities (yolk colour, index and yolk albumin ratio) and cholesterol content. Data collected was analyzed using generalized linear model (SAS, 2009). Mean separation was done using least significance difference at 5%. The results from experiment one showed that inclusion of MLM at 10% increased egg production, feed intake and decreased FCR. In experiment two, inclusion of MLM in the diets had no effect on external qualities except shell thickness that decreased. For objective three, inclusion of MLM in diets had no effect on internal qualities and cholesterol content except yolk colour intensity that increased to deep yellow. In conclusion, MLM should be incorporated at 10% in layer chicken diets to improve egg production and quality.

description: Donor-acceptor cyclopropanes were reacted under Lewis acid catalysis with 3-thioxocyclobutanones as surrogates for disubstituted thioketenes. A broad scope of 2-substituted tetrahydrothiophenes with a semicyclic double bond was obtained under mild conditions with high functional group tolerance and in excellent yield. A sequence of a formal [3 + 2]-cycloaddition followed by the subsequent release of disubstituted ketene is postulated as the mechanism.

description: The kinetics of (3+2) cycloaddition reactions of 18 different donor-acceptor cyclopropanes with the same aldehyde were studied by in situ NMR spectroscopy. Increasing the electron density of the donor residue accelerates the reaction by a factor of up to 50 compared to the standard system (donor group=phenyl), whereas electron-withdrawing substituents slow down the reaction by a factor up to 660. This behavior is in agreement with the Hammett substituent parameter σ. The obtained rate constants from the (3+2) cycloadditions correlate well with data from additionally studied (3+n) cycloadditions with a nitrone (n=3) and an isobenzofuran (n=4). A comparison of the kinetic data with the bond lengths in the cyclopropane (obtained by X-ray diffraction and computation), or the 1 H and 13 C NMR shifts, revealed no correlation. However, the computed relaxed force constants of donor-acceptor cyclopropanes proved to be a good indicator for the reactivity of the three-membered ring.

Year: 2019
Subjects: subject: 547

description: The reactivity of 3,3´-linked bispyrroles, easily accessible by ring-enlargement reactions of donor-acceptor cyclopropanes, towards various carbon electrophiles was investigated. A biscyclopropanated furan, equipped with imines as acceptor units, was converted by rearrangement and subsequent elimination of water to 3,3´-linked bispyrroles. Thereby the nucleophilic 2-position of the pyrroles stayed unsubstituted, thus permitting a further reaction with electrophiles. The heterocycles were reacted with oxalyl chloride to form a new six-membered ring between the pyrrolic subunits. The 1,2-diketone moiety in these species was used as a starting point to extend the π-system via a condensation reaction with aromatic 1,2-diamines. The reaction of 3,3’-linked bispyrroles with the phosgene surrogate triphosgene led to a seven-membered anhydride. The use of the Vilsmeier reagent led to a formylation of the bispyrroles. Furthermore, a direct oxidative coupling between two bispyrroles resulted in a previously unknown linkage (3,3':2',2'':3'',3''') between four pyrrole subunits.

description: The effect of strong anisotropy on the Fermi line of a system of correlated electrons is studied in two space dimensions, using renormalization group techniques. Inflection points change the scaling exponents of the couplings, enhancing the instabilities of the system. They increase the critical dimension for non Fermi liquid behavior, from 1 to 3/2. Assuming that, in the absence of nesting, the dominant instability is towards a superconducting ground state, simple rules to discern between d-wave and extended s-wave symmetry of the order parameter are given.

description: Intermittent or marginally-stable repellers are commonly associated with a power law decay in the survival fraction. We show here that the presence of weak additive noise alters the spectrum of the Perron - Frobenius operator significantly giving rise to exponential decays even in systems that are otherwise regular. Implications for ballistic transport in marginally stable miscrostructures are briefly discussed.

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The abundance of holmium (Z = 67) in the Sun remains uncertain. The photospheric abundance, based on lines of Ho II, has been reported as +0.26 +/- 0.16 (on the usual scale where log(H) = 12.00), while the meteoretic value is +0.51 +/- 0.02. Cowan code calculations have been undertaken to improve the partition function for this ion by including important contributions from unobserved levels arising from the (4f^{11}6p + 4f^{10}(5d + 6s)^{2}) group. Based on 6994 computed energy levels, the partition function for Ho II is 67.41 for a temperature of 6000 K. This is approximately 1.5 times larger than the value derived from the 49 published levels. The new partition function alone leads to an increase in the solar abundance of Ho to log(Ho) = +0.43. This is within 0.08 dex of the meteoretic abundance. Support for this result has been obtained through LTE spectrum synthesis calculations of a previously unidentified weak line at 3416.38 A in the solar spectrum. Attributing the feature to Ho II, the observations may be fitted with log(Ho) = +0.53. This calculation assumes log(gf) = 0.25 and is uncertain by at least 0.1 dex.

description: The first (3+3)-annulation process of donor-acceptor cyclopropanes using synergistic catalysis is reported. The Rh2 (OAc)4 -catalyzed decomposition of diazo carbonyl compounds generated carbonyl ylides in situ. These 1,3-dipoles were converted with donor-acceptor cyclopropanes, activated by Lewis acid catalysis, to afford multiply substituted pyran scaffolds in high yield and diastereoselectivity. Extensive optimization studies enabled access to 9-oxabicyclo[3.3.1]nonan-2-one and 10-oxabicyclo[4.3.1]decen-2-ol cores, exploiting solvent effects on intermediate reactivity.

The condensate is initially prepared in a quasi-one-dimensional harmonic trap. Depending on the system parameters, the ground state can fall in different phases --- single minimum, separated or stripe. Then, suddenly the trapping well is opened at one side. The subsequent dynamics of the condensate is studied by solving nonlinear Schrödinger equations. We found that the diverse phases will greatly change the tunneling escape behavior of SO coupled BECs. In single minimum and separated phases, the condensate escapes the trapping well continuously, while in stripe phase it escapes the well as an array of pulses. We also found that SO coupling has a suppressing effect on the tunnelling escape of atoms. Especially, for BECs without inter-atom interaction, the tunnelling escape can be almost completely eliminated when the system is tuned near the transition point between single minimum and stripe phase. Our work thus suggests that SO coupling may be a useful tool to control the tunnelling dynamic of BECs, and potentially be applied in realization of atom lasers and matter wave switches.

description: We analyse in details the problems which one faces trying to quantize a scalar field on the spacelike cylinder being the simple example of a spacetime with closed timelike curves. Our analysis brings to light the fact that the usual set of positive and negative frequency solutions of the field equation turns out to be incomplete. The consequence of this fact is that the usual formulation of quantum field theory breaks down on such a spacetime. We postulate the completeness principle and build on its basis the modified quantization procedure. As an example, the Hadamard function and $$ for the scalar field on the spacelike cylinder are calculated. It is shown that the ``naive'' method of images gives the same results of calculation.

description: The coming 10-20 years will be most critical for making the transition to a global food system in which all stakeholders look at food and nutrients in a holistic manner, including their hidden environmental, health and socio-economic costs. Consumers as well as governments and other stakeholders need to support such a transformation because farmers and the industry supporting them will not be able to implement all of the required actions alone. The outcome of this transformation will be a new societal plant nutrition optimum rather than a purely economic optimum. The new nutrient economy will become an integral component of a low carbon emission, environment-friendly and circular economy, supporting the food and nutrition requirements of a rising global population and improving the income and livelihood of farmers worldwide.

description: Novel dyes based on extended fulvene motifs are reported. The carbon skeleton was generated by a catalyzed addition of donor-acceptor cyclopropanes to naphthoquinone. The hydroxy group at the central ring of the tricyclic fulvene motif was converted into the triflate, which reacted efficiently with a wide range of nucleophiles, resulting in substitution and thereby providing new derivatives. The synthetic versatility allowed us to investigate the absorption, electrochemical, and UV/Vis-NIR spectroelectrochemical properties of these dyes as a function of the substituents. The dyes were shown to participate in reductive electrochemistry, the reversibility of which can be improved by appropriate selection of the substituents. Additionally, first signs of NIR electrochromism are presented, opening new avenues for the future investigations of such dyes.

description: Low soil fertility associated with nutrient mining of both macro and micronutrients and soil acidity is a major constraint affecting crop production in Western Kenya. The objectives of this study were (i) to determine the effect of customized fertilizer and lime on common bean (Phaseolus vulgaris L.) growth and yield and (ii) to determine the effect of selected micronutrient (boron, zinc and molybdenum) with lime on their uptake and growth of common bean. In the first experiment, a field experiment was conducted on 2 sites of Kapkerer and Kiptaruswo, Nandi County. A 4 × 2 factorial experiment was set up in randomized complete block design. The treatments were Mavuno fertilizer (15:10:18: plus sulphur, calcium, magnesium, iron copper, boron and molybdenum) (0, 185 kg ha-1), Sympal fertilizer (0:23:15 calcium, magnesium, sulphur and zinc) (0, 125 kg ha-1), Diammonium phosphate fertilizer (positive control) (0, 62.5 kg ha-1) and lime (0, and 1.6 or 2.0 t ha-1 depending on specific lime requirement for the site). Yield, phosphorous uptake, below and aboveground biomass were determined. In the second experiment, a greenhouse experiment was conducted at Egerton University using soil from Kapkerer site. A 2 × 2 × 2 × 2 factorial experiment was set up in completely randomized design. The treatments were, boron (0, 3 kg ha-1), zinc (0, 1.5 kg ha-1) Mo (0, 0.6 kg ha-1) and lime (0, 1.6 t ha-1). Plant tissue analysis for micronutrient uptake (boron, zinc and molybdenum) above and below-ground biomass were determined. The results showed that application of lime increased above and belowground biomass, nutrient uptake and yield in common bean while combined application of Mavuno fertilizer with lime further enhanced common bean growth and increased yields by 42%, 30% and 27%, respectively, compared to control, Sympal and DAP. Application of DAP and Sympal in combination with lime did not have a significant effect on common bean yield. On the other hand, the application of boron with molybdenum significantly increased above and below-ground biomass by 24% and 32%, respectively, compared with the control. The application of boron and lime significantly increased aboveground biomass by 11%, while molybdenum with lime application significantly increased belowground biomass by 29%. The results for this study suggest that the use of Mavuno fertilizer formulation can significantly improve common bean productivity in Western Kenya smallholder systems, and inclusion of boron and molybdenum in the fertilizer and liming the soil is necessary for enhanced common bean productivity.

description: Gum Arabic (GA) has been used over centuries in food processing for functions such as emulsification, stabilization, encapsulation, bulking and thickening. However, use of GA from Acacia senegal var. kerensis in sucrose reduced jam has not been reported despite its potential functional properties.Reducing caloric intake from sucrose is advisable for people with metabolic syndrome but reducing the amount of sugar in jam has an effect on the physico-chemical properties of the product. Thus, other co-solutes must be added to counter the effect and maintain the quality of the jam. Therefore, the objective of this study was to use gum Arabic from Acacia senegal var. kerensis in formulation of a reduced sugar jam from plums and pineapple fruits. The jams were analyzed for physico-chemical and rheological properties, sensory attributes and shelf-life. The experiment employed a completely randomized design in a factorial arrangement. Data obtained was analyzed using PROCGLM procedure of the statistical analysis system version 9.1.3. The main effect of the study was the level of gum Arabic at 15% and 20%, level of sugar content, 30% and 35%, and the type of fruit. A control product was prepared for the two sugar levels but without gum Arabic. Jam with gum Arabic had higher ash (1.7%), fibre (0.57) and vitamin C content (1.4mg/100g) at p<0.05. Moisture content reduced as gum level increased from 49.44% (control) to 40.12% (20% gum). On sensory parameters, fruit type significantly affected the color at p<0.05. Plum jam was preferred in colour. Gum Arabic significantly affected the taste at p<0.001 with the control having a score of 6.21 compared to 5.82 and 5.68 for jam containing 15% and 20%GA, respectively. Pineapple jam containing 30% sucrose was preferred to one with 35% sucrose.The jam was shelf stable for longer than the anticipated storage time of one month. Sucrose content was reduced from the maximum allowed content of 65% to 35% and 30% for plum and pineapple jam,respectively, while retaining the total soluble solids above 60˚ Brix. Therefore, it is possible to reduce the amount of sugar by 50% by adding 15% GA from Acacia senegal var. kerensis and maintain acceptable physico-chemical, rheological, sensory and shelf-life of the pineapple and plum jam. The products of this work can be used as a dietetic jam for people who are conscious about high caloric intake from sugar and individuals with metabolic syndrome.

description: This research explores the fundamental nature of time as an emergent structured energy flow, governed by the balance between quanta and dark matter. Through simulations and mathematical derivations, we establish that time manifests as an oscillatory energy force influenced by universal constants, external energy distortions such as black holes and high-energy fields, and pre-space stabilization. We provide a framework for time manipulation, including localized distortions, black hole-driven time dilation, and stable time zones where time flows at different rates. Our findings redefine time as an active stabilizing function rather than a passive dimension, providing the foundation for future advancements in time engineering.
