description: We study the tunneling through delta and double delta potentials in fractional quantum mechanics. After solving the fractional Schrödinger equation for these potentials, we calculate the corresponding reflection and transmission coefficients. These coefficients have a very interesting behaviour. In particular, we can have zero energy tunneling when the order of the Riesz fractional derivative is different from 2. For both potentials, the zero energy limit of the transmission coefficient is given by $\mathcal{T}_0 = \cos^2{π/α}$, where $α$ is the order of the derivative ($1 < α\leq 2$).

description: Computer simulations are used to test whether a recently introduced generalization of Rosenfeld's excess-entropy scaling method for estimating transport coefficients in systems obeying molecular dynamics can be extended to predict long-time diffusivities in fluids of particles undergoing Brownian dynamics in the absence of interparticle hydrodynamic forces. Model fluids with inverse-power-law, Gaussian-core, and Hertzian pair interactions are considered. Within the generalized Rosenfeld scaling method, long-time diffusivities of ultrasoft Gaussian-core and Hertzian particle fluids, which display anomalous trends with increasing density, are predicted (to within 20%) based on knowledge of interparticle interactions, excess entropy, and scaling behavior of simpler inverse-power-law fluids.

description: Dairy Research Centre in SW Scotland is a fully functioning commercial research farm that compares two contrasting systems: · one using feeds grown and supplied within the boundaries of the farm: · the other uses feedstocks that are provided as by-products from the agri-food industries. These contrasting systems are used to support separate herds of dairy cattle. The basis of the home-grown system is that all feed, except minerals and vitamins, are grown on the farm. If insufficient amount of an individual feed was grown, then the same feed was purchased and the land allocation extended using the crop yield achieved on the farm. The only feeds which have been purchased are field beans. The system was designed to achieve milk sales of about 7,000 litres/cow /year. The basis of by-products system is that the cows are fed on by-products (or co-products) which are not normally used in human diets. There is therefore no direct requirement for land although all the feeds can be traced back to the land they were originally grown on. In order to ensure a difference in milk sales between this system and the home-grown system the rations were formulated to achieve milk sales of about 11,000 litres /cow / year. The cows are housed all year with access to a roofed loafing area during the summer months.

description: We quantify the extractable entanglement of excited states of a Lieb-Liniger gas that are obtained from coarse-grained measurements on the ground state in which the boson number in one of two complementary contiguous partitions of the gas is determined. Numerically exact results obtained from the coordinate Bethe ansatz show that the von Neumann entropy of the resulting bipartite pure state increases monotonically with the strength of repulsive interactions and saturates to the impenetrable boson limiting value. We also present evidence indicating that the largest amount of entanglement can be extracted from the most probable projected state having half the number of bosons in a given partition. Our study points to a fundamental difference between the nature of the entanglement in free-bosonic and free-fermionic systems, with the entanglement in the former being zero after projection, while that in the latter (corresponding to the impenetrable boson limit) being non-zero.

description: In order to assess the attractiveness of flowers to pollinators, it is necessary to observe and record the insects that visit. Timed observations are performed, during which a record of each insect and its activity is made. Our observations have been of Vicia faba and Phaseolus vulgaris but the same method can be applied to other species of flowering plant. Honeybees (Apis mellifera) and Bumblebees (Bombus spp.) are recorded to species level if possible and bees from other genera recorded as ‘other bees’. Buff-tailed bumblebees (Bombus terrestris) and white-tailed bumblebees (Bombus lucorum) are grouped as ‘buff/white-tailed’ as differentiation is not always possible in the field, particularly for the worker caste. The primary activities recorded are ‘nectaring’ (N), ‘nectar-robbing’ (NR), ‘resting’ (R) and ‘searching’ (S). In the case of Vicia faba, feeding from extra-floral nectaries is also noted (EFR).

description: Ornamental traits such as ultraviolet (UV) fluorescence and reflectance can provide honest signals indicating the bearer’s condition as a potential mate. UV fluorescence is widely found in nature and used for multiple functions, such as indicating female maturity in arachnids and acting as a signal enhancer in many insects. Lizards can display a broad range of colours, but the function of some of their ornamental traits remains unclear. Here, we report the presence of UV fluorescence in female Eremias argus specimens, a small lizard ranging across Mongolia, China and the Korean Peninsula. Based on our observation, combined with the literature on the breeding behaviour of the species, we provide two hypotheses, assigning the use of UV fluorescence to: 1) an indicator of females body conditions and 2) signal efficacy backup. To verify our hypotheses, we suggest a protocol with three serial trials under low light and enhanced UV light conditions.

Chlorophyll Fluorescence
Creators: name: Ntatsi Georgia, Savvas Dimitrios
Publisher: name: Zenodo
Year: 2018

description: Light energy absorbed by chlorophyll molecules in a leaf can undergo one of three fates: used to drive photosynthesis (photochemistry); excess energy can be dissipated as heat; re‐emitted as light—chlorophyll fluorescence. Βy measuring the yield of chlorophyll fluorescence, information about changes in the efficiency of photochemistry and heat dissipation can be gained. This is due to the fact that light energy absorbed by chlorophyll molecules can either used to drive photosynthesis or the excess energy can be dissipated as heat or it can be re-emitted as chlorophyll fluorescence (taken from Maxwell et al., 2000). Non-photochemical quenching is the quenching of chlorophyll fluorescence and is thought to be involved in protecting the photosynthetic machinery against over-excitation and subsequent damage.

description: We measure the luminosity and color dependence of galaxy clustering in the SDSS DR7 main galaxy sample, focusing on the projected correlation function w_p(r_p) of volume-limited samples. We interpret our measurements using halo occupation distribution (HOD) modeling assuming a Lambda-CDM cosmology. The amplitude of w_p(r_p) grows slowly with luminosity for L < L_* and increases sharply at higher luminosities, with bias factor b(>L)=1.06+0.23(L/L_*)^{1.12}. At fixed luminosity, redder galaxies have a stronger and steeper w_p(r_p), a trend that runs steadily from the bluest galaxies to the reddest galaxies. The individual luminosity trends for the red and blue galaxy populations are strikingly different. Blue galaxies show a slow but steady increase of w_p(r_p) with luminosity, at all scales. The large-scale clustering of red galaxies shows little luminosity dependence until a sharp increase at L > 4L_*, but the lowest luminosity red galaxies (0.04-0.25 L_*) show very strong clustering on scales r_p < 2 Mpc/h. Most of the observed trends can be naturally understood within the LCDM+HOD framework. The growth of w_p(r_p) with luminosity reflects an overall shift in the halo mass scale, in particular an increase in the minimum host halo mass Mmin. The mass at which a halo has, on average, one satellite galaxy brighter than L is M_1 ~ 17 Mmin(L) over most of the luminosity range. The growth and steepening of w_p(r_p) for redder galaxies reflects the increasing fraction of galaxies that are satellite systems in high mass halos instead of central systems in low mass halos, a trend that is especially marked at low luminosities. Our extensive measurements, provided in tabular form, will allow detailed tests of theoretical models of galaxy formation, a firm grounding of semi-empirical models of the galaxy population, and new cosmological tests.

Patterns of genotype-environment interactions and sensitivity to genomic selection in the lodgepole pine breeding program in British Columbia
Creators: name: Ukrainetz, Nicholas Karl
Publisher: name: University of British Columbia
Year: 2020

description: Lodgepole pine (Pinus contorta Dougl. ex. Loud.) is an important tree species in British Columbia, Canada, both commercially and ecologically. Much of the seed used for reforestation after harvesting and wildfires is produced by seed orchards that rely on an extensive breeding program. Tree breeders require tools to adjust quickly to unforeseen challenges exacerbated by a changing climate and two approaches were examined: mulit-environment trial (MET) analyses and genomic selection. A MET dataset was used to analyse height growth data across five breeding zones using a factor analytic model for estimating additive (co)variance among test sites and the use of molecular markers to predict breeding values for height growth and wood quality traits (average wood density, earlywood density, latewood density, latewood proportion and microfibril angle) was assessed for a subsample of 1,569 trees from four progeny test sites using 19,584 single-nucleotide polymorphism markers. Test sites were clustered into four main breeding zones based on genetic correlations between sites. Climate change projections were applied to the four new zones which suggested that southern zones will expand. Predicted breeding values from Bayesian models (Bayes B and C) and best linear unbiased prediction (BLUP) using a hybrid matrix (H-matrix) were compared to models that used an average relationship matrix (ABLUP) and a realized relationship matrix (GBLUP). Bayesian models had similar prediction accuracies compared to ABLUP and GBLUP when models were confined to a closed population (> 0.74), but accuracy decreased substantially when relatedness was controlled between the training and validation populations (> 0.25). The models also worked well across environments and test cycles and were similar to GBLUP for ranking trees within families. HBLUP was equivalent to ABLUP and GBLUP models for genetic parameters and prediction accuracy, but had very low within-family rank correlations (0.08 average Spearman rank correlation across traits). Bayesian models can be used to predict breeding values and rank trees that have no phenotypic data. In contrast, HBLUP should not be used for ranking trees within families in the absence of phenotypic data, but can effectively improve estimates of variance components and breeding value estimates.

Spatial and temporal variability of internal wave-driven mixing in the Arctic Ocean
Creators: name: Chanona, Melanie
Publisher: name: University of British Columbia
Year: 2020

description: The Arctic Ocean is a unique oceanographic environment that sits at the frontier of the impacts of climate change. In light of the ongoing dramatic changes observed in the Arctic Ocean, there has been a growing interest in improving our understanding of turbulent ocean mixing rates, which play an integral role in setting numerous oceanographic properties. However, scarcity of direct turbulence measurements in the Arctic Ocean inhibits our ability to robustly quantify the space-time variability of mixing in this region and understand the mechanisms that underpin it. This thesis addresses this issue by employing a finescale parameterization of turbulent dissipation to estimate turbulent mixing metrics from three unique Arctic Ocean datasets that span a wide range of distinct space and time scales. Key results include the following. First, estimated internal wave-driven dissipation rates span multiple orders of magnitude, both across large geographic domains and temporally on local scales. Despite this wide variability, dissipation rates display distinct regional differences, with estimated turbulent metrics that are consistently higher on the Canadian Arctic shelf than in the central basins. Dissipation rate time series also vary systematically at key tidal frequencies and on seasonal time scales, but exhibit no interannual trends on periods of up to 16 years. Additionally, a characterization of mixing regimes reveals large-scale spatial structure in the distribution of turbulent, non-turbulent, and marginal mixing regimes. Non-turbulent conditions are most prevalent, but wide variability implies that turbulent mixing occurs in all regions at least some of the time. Finally, dissipation rate estimates from each dataset provide consistent, statistically-significant evidence that tidal forcing and stratification strength modulate turbulence more strongly than wind speed, topographic roughness, or sea ice cover; however, the correlations between each of these metrics and turbulence are generally weak. Overall, the primary contribution of this thesis is the provision of an improved statistical characterization of turbulent metrics in the Arctic Ocean on unprecedented spatial and temporal scales. This characterization puts more limited mixing measurements into a broader context and further provides a valuable observational baseline that can be used to inform Arctic Ocean modelling studies.
Isospin splittings of doubly heavy baryons

description: The SELEX Collaboration has reported a very large isospin splitting of doubly charmed baryons. We show that this effect would imply that the doubly charmed baryons are very compact. One intriguing possibility is that such baryons have a linear geometry Q-q-Q where the light quark q oscillates between the two heavy quarks Q, analogous to a linear molecule such as carbon dioxide. However, using conventional arguments, the size of a heavy-light hadron is expected to be around 0.5 fm, much larger than the size needed to explain the observed large isospin splitting. Assuming the distance between two heavy quarks is much smaller than that between the light quark and a heavy one, the doubly heavy baryons are related to the heavy mesons via heavy quark-diquark symmetry. Based on this symmetry, we predict the isospin splittings for doubly heavy baryons including Xi_{cc}, Xi_{bb} and Xi_{bc}. The prediction for the Xi_{cc} is much smaller than the SELEX value. On the other hand, the Xi_{bb} baryons are predicted to have an isospin splitting as large as (6.3\pm1.7) MeV. An experimental study of doubly bottomed baryons is therefore very important to better understand the structure of baryons with heavy quarks.

description: A finite set X in a metric space M is called an s-distance set if the set of distances between any two distinct points of X has size s. The main problem for s-distance sets is to determine the maximum cardinality of s-distance sets for fixed s and M. In this paper, we improve the known upper bound for s-distance sets in n-sphere for s=3,4. In particular, we determine the maximum cardinalities of three-distance sets for n=7 and 21. We also give the maximum cardinalities of s-distance sets in the Hamming space and the Johnson space for several s and dimensions.

Approximate twistors and positive mass

description: In this paper the problem of comparing initial data to a reference solution for the vacuum Einstein field equations is considered. This is not done in a coordinate sense, but through quantification of the deviation from a specific symmetry. In a recent paper [T. Bäckdahl, J.A. Valiente Kroon, Phys. Rev. Lett. 104, 231102 (2010)] this problem was studied with the Kerr solution as a reference solution. This analysis was based on valence 2 Killing spinors. In order to better understand this construction, in the present article we analyse the analogous construction for valence 1 spinors solving the twistor equation. This yields an invariant that measures how much the initial data deviates from Minkowski data. Furthermore, we prove that this invariant vanishes if and only of the mass vanishes. Hence, we get a proof of the positivity of mass.

description: We propose an analytic treatment for computing the relic abundances of non-relativistic particles whose annihilation rate at chemical decoupling is increased by Sommerfeld enhancement. We find approximate rational functions that closely fit the thermal average of Sommerfeld-enhanced cross sections in the massless limit of force carriers for s- and p-wave annihilations. We demonstrate that, with the approximate thermally-averaged cross sections implemented, the standard analytic method for the final relic abundances provides accuracy to within 1% even for the case of Sommerfeld enhancement.

description: Segmenting cells within cellular aggregates in 3D is a growing challenge in cell biology, due to improvements in capacity and accuracy of microscopy techniques. Here we describe a pipeline to segment images of cell aggregates in 3D. The pipeline combines neural network segmentations with active meshes. We apply our segmentation method to cultured mouse mammary duct organoids imaged over 24 hours with oblique plane microscopy, a high-throughput light-sheet fluorescence microscopy technique. We show that our method can also be applied to images of mouse embryonic stem cells imaged with a spinning disc microscope. We segment individual cells based on nuclei and cell membrane fluorescent markers, and track cells over time. We describe metrics to quantify the quality of the automated segmentation. Our segmentation pipeline involves a Fiji plugin which implement active meshes deformation and allows a user to create training data, automatically obtain segmentation meshes from original image data or neural network prediction, and manually curate segmentation data to identify and correct mistakes. Our active meshes-based approach facilitates segmentation postprocessing, correction, and integration with neural network prediction.

description: An edge-coloring of a graph 𝐺 with consecutive integers 𝑐1,…,𝑐𝑡 is called an interval t-coloring, if all colors are used, and the colors of edges incident to any vertex of 𝐺 are distinct and form an interval of integers. A graph 𝐺 is interval colorable, if it has an interval t-coloring for some positive integer 𝑡. For an interval colorable graph 𝐺, 𝑤(𝐺) denotes the smallest value of 𝑡 for which 𝐺 has an interval t-coloring. A block graph is a type of graph in which every biconnected component (block) is a clique. Even block graphs are a subclass of block graphs where each block has an even number of vertices. In this paper we show that any even block graph has an interval edge-coloring with 𝑤(𝐺)≤2⋅(Δ(𝐺)−1). Furthermore, we show that this upper bound can not be improved for even block graphs.

description: Sinelater perroti (Fleutiaux, 1940) (Elateridae: Tetralobinae)
were collected using a mercury light trap. Members of Tetralobinae (sensu Kundrata et al. 2018 and Douglas et al. 2021) include some of the largest click beetles ever reported (Costa et al. 1994).To date, the Tetralobinae fauna in India is represented by a single species, Tetralobus duchoni Schwarz, 1905 (Kubaczkova and Kundrata 2017) from Kohima, Nagaland (then Assam; Schwarz 1905). In this paper, we report S. perroti for the first time from India and provide images of adults and male genitalia. The specimens were compared with the type photographs as well as the original description. Recently, this species was reported by Qiu et al. (2020) from China (Tibet, Yunnan), Laos, and Myanmar.
For genitalia dissection, the specimens were relaxed overnight in a relaxation box and the genitalia capsule was pulled from the abdomen using forceps. The genitalia were dissected, rinsed with water, dehydrated in ethanol and preserved in a vial with glycerin. Morphological terminology used mainly follows Kundrata et al. (2018). General morphological characters were studied using a Leica stereo zoom microscope M205C and M205FA and imaging was done using a Leica MC 190HD and Leica EC 4 digital camera and with the help of a Sony DSC-HX400V digital camera. Adobe Photoshop 7 software was used for processing the images. Voucher specimens are deposited in the National Pusa Collection (NPC), Division of Entomology, ICAR-IARI, New Delhi, India. The size range of specimens collected from India varied from 53 to 64 mm, which is slightly longer (Figs. 1A, B) than the body length reported by Qiu et al. (2020), i.e., 43–60 mm. Male genitalia: Stout, phallobase basal margin nearly straight; paramere with lateral margin almost parallel along basal one-third of length, apex elongate-triangular, pointed; median lobe 0.9× shorter than the parameres, broader at base and gradually tapering toward round apex, basal strut long, reaching middle of phallobase (Figs. 1C, D).

description: In this report we construct a phenomenological model in which the time variation of the fine structure constant, $α$, is induced by a parity and charge-parity (PCP) violating interaction. Such a PCP violation in the photon sector has a distinct physical origin from that in the conventional models of this kind. We calculate the cosmological birefringence so induced in our model and show that it in turn produces a new non-vanishing multipole moment correlation between the temperature and the polarization anisotropies in the CMB spectrum. We have also calculated the amount of optical rotation due to a strong background magnetic field and the effect of our new PCP violating term on the variation of $α$ during the cosmic evolution. We found that only in the radiation dominated era can the contribution of the new PCP violating term to the variation of $α$ be non-vanishing.

description: We develop the theory of Abelian functions associated with algebraic curves. The growth in computer power and an advancement of efficient symbolic computation techniques has allowed for recent progress in this area. In this paper we focus on the genus three cases, comparing the two canonical classes of hyperelliptic and trigonal curves. We present new addition formulae, derive bases for the spaces of Abelian functions and discuss the differential equations such functions satisfy.

description: Background Commonly OPMDs are clinically identifiable diseases that further progress to oral squamous cell carcinoma (OSCC). Oral Submucous Fibrosis (OSMF), now worldwide acknowledged as the disease of “Southeast Asia and Indian subcontinent”, has the utmost malignant transformation prevalence amongst OPMDs. “Oral premalignant lesions” showing epithelial dysplasia are at a fifteen times higher risk of malignant alterations. So microscopic recognition of epithelial dysplasia is helpful for the assessment of malignant transformation in OSMF. Increased vascularity that is neoangiogenesis has been observed in the superficial connective tissue region of premalignant lesions showing dysplasia. Epithelial dysplasia exhibits a considerable character in the carcinomatous transformation of “OSMF”. This research project is designed with the premise that whether the neoangiogenesis (CD-105) is significant in the alteration of the “extracellular matrix” in OSMF, and “OSCC with OSMF”? Methods  The project comprised 30 normal oral mucosa samples “(group I)”, 30 clinicopathologically diagnosed cases of “OSMF (group II)”, and on the basis of association of OSMF, 30 surgically operated and histopathologically diagnosed cases of OSCC of various histopathological grades which will be retrieved from the departmental archives (group III). The archival tissue section of 4μm will be obtained for Group I, II, and III. Haematoxylin and Eosin stains will be used for routine staining procedures and immunohistochemistry for the expression of CD105. Oral epithelial dysplasia (OED) in OSMF will be recorded on the basis of its presence or absence. Further, cases will be categorized into two groups, “low-risk epithelial dysplasia” (LRED) and “high-risk epithelial dysplasia (HRED)”. Conclusion There is progressively increased vascularity which is observed by MVD, TVA, and MVA (CD-105) expression from normal to LRED, HRED, and OSCC cases. This observation gives emphasis to the significance of angiogenesis in tumor development and its further progression.

description: We present large scale 3D particle-in-cell (PIC) simulations to examine particle energization in magnetic reconnection of relativistic electron-positron (pair) plasmas. The initial configuration is set up as a relativistic Harris equilibrium without a guide field. These simulations are large enough to accommodate a sufficient number of tearing and kink modes. Contrary to the non-relativistic limit, the linear tearing instability is faster than the linear kink instability, at least in our specific parameters. We find that the magnetic energy dissipation is first facilitated by the tearing instability and followed by the secondary kink instability. Particles are mostly energized inside the magnetic islands during the tearing stage due to the spatially varying electric fields produced by the outflows from reconnection. Secondary kink instability leads to additional particle acceleration. Accelerated particles are, however, observed to be thermalized quickly. The large amplitude of the vertical magnetic field resulting from the tearing modes by the secondary kink modes further help thermalizing the non-thermal particles generated from the secondary kink instability. Implications of these results for astrophysics are briefly discussed.

description: We study the transmission spectra of ultracold rubidium atoms coupled to a high-finesse optical cavity. Under weak probing with pi-polarized light, the linear response of the system is that of a collective spin with multiple levels coupled to a single mode of the cavity. By varying the atom number, we change the collective coupling of the system. We observe the change in transmission spectra when going from a regime where the collective coupling is much smaller than the separation of the atomic levels to a regime where both are of comparable size. The observations are in good agreement with a reduced model we developed for our system.

Gravitational waves from nonspinning black hole-neutron star binaries: dependence on equations of state

description: We report results of a numerical-relativity simulation for the merger of a black hole-neutron star binary with a variety of equations of state (EOSs) modeled by piecewise polytropes. We focus in particular on the dependence of the gravitational waveform at the merger stage on the EOSs. The initial conditions are computed in the moving-puncture framework, assuming that the black hole is nonspinning and the neutron star has an irrotational velocity field. For a small mass ratio of the binaries (e.g., MBH/MNS = 2 where MBH and MNS are the masses of the black hole and neutron star, respectively), the neutron star is tidally disrupted before it is swallowed by the black hole irrespective of the EOS. Especially for less-compact neutron stars, the tidal disruption occurs at a more distant orbit. The tidal disruption is reflected in a cutoff frequency of the gravitational-wave spectrum, above which the spectrum amplitude exponentially decreases. A clear relation is found between the cutoff frequency of the gravitational-wave spectrum and the compactness of the neutron star. This relation also depends weakly on the stiffness of the EOS in the core region of the neutron star, suggesting that not only the compactness but also the EOS at high density is reflected in gravitational waveforms. The mass of the disk formed after the merger shows a similar correlation with the EOS, whereas the spin of the remnant black hole depends primarily on the mass ratio of the binary, and only weakly on the EOS. Properties of the remnant disks are also analyzed.

description: The weak magnetic field induced reduction of the low-temperature superfluid density in cuprate superconductors is studied based on the kinetic energy driven superconducting mechanism. The electromagnetic response kernel is evaluated by considering both couplings of the electron charge and electron magnetic momentum with a weak magnetic field and employed to calculate the superfluid density, then the main features of the weak magnetic field induced reduction of the low-temperature superfluid density are well reproduced. The theory also shows that the striking behavior of the weak magnetic field induced reduction of the low-temperature superfluid density is intriguingly related to both depairing due to the Pauli spin polarization and nonlocal response in the vicinity of the d-wave gap nodes on the Fermi surface to a weak magnetic field.
