description: Hybrid Higgs inflation model is a hybrid type of the so-called Higgs inflation model with the conventional non-minimal $ξ$ coupling to a scalar curvature $R$ and new Higgs inflation model with the derivative coupling to the Einstein curvature tensor $G_{μν}$. This model can explain all possible value of the tensor-to-scalar ratio $r$ allowed by the present CMB constraints with an appropriate choice of coupling parameters. However the derivative coupling may causes a gradient instability during oscillation phase after inflation just as in new Higgs inflation model. Analyzing the behaviours of perturbations during oscillation phase in the hybrid Higgs inflation model, we show that the unstable scalar modes found in new Higgs inflation model are stabilized by the non-minimal $ξ$ coupling for some range of the coupling parameters.

description: Vehicular congestion is directly impacting the efficiency of the transport sector. A wireless sensor network for vehicular clients is used in Internet of Vehicles based solutions for traffic management applications. It was found that vehicular congestion detection by using Internet of Vehicles based connected vehicles technology are practically feasible for congestion handling. It was found that by using Fog Computing based principles in the vehicular wireless sensor network, communication in the system can be improved to support larger number of nodes without impacting performance. In this paper, connected vehicles technology based vehicular congestion identification techniques are studied. Computing paradigms that can be used for the vehicular network are studied to develop a practically feasible vehicular congestion detection system that performs accurately for a large coverage area and multiple scenarios. The designed system is expected to detect congestion to meet traffic management goals that are of primary importance in intelligent transportation systems.

description: Rydberg tweezer arrays provide a versatile platform to explore quantum magnets with dipolar XY or van-der-Waals Ising ZZ interactions. Here, we propose a scheme combining dipolar and van-der-Waals interactions between two Rydberg states, where the amplitude of the latter can be greater than that of the former, realizing an extended Hubbard model with long-range tunnelings in optical tweezer arrays. On the triangular lattice with repulsive interactions, we predict the existence of a robust supersolid phase with a critical entropy per particle $S/N \approx 0.19$ accessible in current Rydberg tweezer experiments supported by large-scale quantum Monte Carlo simulations. We further demonstrate the experimental feasibility by identifying pairs of Rydberg states in ${}^{87}$Rb realizing the required interactions. Such a lattice supersolid is long-lived, found over a wide parameter range in an isotropic and flat two-dimensional geometry, and can be realized for 100s of particles allowing one to directly probe the defect-induced picture of supersolids. Its thermodynamical and dynamical properties can hence be studied at a far larger scale than hitherto possible.

description: To manipulate cold atoms in spatially constrained quantum engineering platforms, we developed a lensless optical system with a $\sim$1 $μ$m resolution and a transverse size of only 225 $μ$m. We use a multimode optical fiber with a high numerical aperture, which directly guides light inside the ultra-high-vacuum system. Spatial light modulators allow us to generate control beams at the in-vacuum fiber end by digital optical phase conjugation. As a demonstration, we use this system to optically transport cold atoms towards the in-vacuum fiber end, to load them in optical microtraps and to re-cool them in optical molasses. This work opens new perspectives for setups combining cold atoms with other optical, electronic or opto-mechanical systems with limited optical access.

Length-preserving biconnection gravity and its cosmological implications

description: We consider a length-preserving biconnection gravitational theory, inspired by information geometry, which extends general relativity by using the mutual curvature as the fundamental object describing gravity. The two connections used to build up the theory are the Schrödinger connection, and its dual. It can be seen that the dual of a non-metric Schrödinger connection possesses torsion, even if the Schrödinger connection itself does not, and consequently the pair $(M,g,\nabla^{*})$ is a quasi-statistical manifold. The field equations are postulated to have the form of the standard Einstein equations, but with the Ricci tensor- and scalar replaced with the mutual curvature tensor- and scalar, resulting in additional torsion-dependent terms. The covariant divergence of the matter energy-momentum does not vanish in this theory. We derive the equation of motion for massive particles, which shows the presence of an extra force. The Newtonian limit of the equations of motion is also considered. We explore the cosmological implications by deriving the generalized Friedmann equations for the FLRW geometry. They contain additional terms that can be interpreted as describing an effective, geometric type dark energy. We examine two cosmological models: one with conserved matter, and one where dark energy and pressure are related by a linear equation of state. The predictions of both models are compared with a set of observational values of the Hubble function, and with the standard $Λ$CDM model. Length-preserving biconnection gravity models fit well the observational data, and also align with $Λ$CDM at low redshifts $(z<3)$. The obtained results suggest that a modified biconnection geometry could explain the late-time acceleration, as well as the formation of the supermassive black holes, since they predict a different age of our Universe as compared to standard cosmology.

description: Several proposals for quantum computation utilize a lattice type architecture with qubits trapped by a periodic potential. For systems undergoing many body interactions described by the Bose-Hubbard Hamiltonian, the ground state of the system carries number fluctuations that scale with the number of qubits. This process degrades the initialization of the quantum computer register and can introduce errors during error correction. In an earlier manuscript we proposed a solution to this problem tailored to the loading of cold atoms into an optical lattice via the Mott Insulator phase transition. It was shown that by adding an inhomogeneity to the lattice and performing a continuous measurement, the unit filled state suitable for a quantum computer register can be maintained. Here, we give a more rigorous derivation of the register fidelity in homogeneous and inhomogeneous lattices and provide evidence that the protocol is effective in the finite temperature regime.

Now Cracticus quoyi jardini Mathews, 1912. See Amadon, 1951: 12; 1962b: 168; Schodde and Mason, 1999: 534–536; Dickinson, 2003: 463; Russell and Rowley, 2009: 337; and Kearns et al., 2011.
HOLOTYPE: AMNH 673191, adult male, collected at Cape York, north Queensland, Australia, on 2 September 1911, by J.P. Rogers (no. 2017). From the Mathews Collection (no. 9785) via the Rothschild Collection.
COMMENTS: In the original description, Mathews cited his catalog number of the holotype and gave the range of jardini as ‘‘ Queensland (Cape York).’’ Two of the specimens collected by Kemp for Mathews on Cape York were cataloged before the 18 September 1912 publication date of jardini; they are paratypes: Utingu, AMNH 673187 (Mathews no. 12879), male, 13 May 1912, AMNH 673190 (13911), female, 26 June 1912. AMNH 673181 was collected on Cape York by W.R. McLennan on 31 January 1911 and had been in Mathews’ collection. I was unable to find it in Mathews catalog and do not know when he obtained it; it is possibly a paratype.
See Schodde and Mason (1999: 534–536) and Kearns et al. (2011) for recognition of jardini.

description: The probability for the exclusion of eigenvalues from an interval $(-x,x)$ symmetrical about the origin for a scaled ensemble of Hermitian random matrices, where the Fredholm kernel is a type of Bessel kernel with parameter $ a $ (a generalisation of the sine kernel in the bulk scaling case), is considered. It is shown that this probability is the square of a $τ$-function, in the sense of Okamoto, for the Painlevé system \PIII. This then leads to a factorisation of the probability as the product of two $τ$-functions for the Painlevé system \PIIIdash. A previous study has given a formula of this type but involving \PIIIdash systems with different parameters consequently implying an identity between products of $τ$-functions or equivalently sums of Hamiltonians.

description: This study aimed to provide a basis for the rational improvement of the microstructure of the soil that had been planted with crops for a long time. Conventional and micro-morphological methods were used to study the effects of planting grain and cotton crops on soil properties in Gaotang County, Shandong Province. The results showed that long-term cultivation of grain and cotton crops has a significant impact on soil micro-structure. The top soil (0-10 cm) of wheat-maize field has higher organic matter content, uniform aggregate size, high separation, and strong packing void connectivity, forming a type micro-structure that is conducive to agricultural production. The characteristics of soil matrix are mainly inherited from soil parent materials, and the impact of crop cultivation on soil matrix is very weak. The amount of formations in the soil is less, and only Fe nodules, Mn nodules and excrement are observed.

description: Este número dos Cadernos BAD, consagrado à problemática da formação, constitui-se como uma espécie de lançamento do 8.º Congresso Nacional de Bibliotecários, Arquivistas e Documentalistas, que decorrerá no Estoril, em Maio de 2004. Subordinado ao lema "Nas encruzilhadas da informação e da cultura: (re)inventar a profissão", o Congresso centrar-se-á sobre as temáticas da formação e da profissão. O estado da formação profissional na área BAD em Portugal tem sido uma preocupação dos profissionais portugueses e da sua Associação. No entanto, apesar de algumas iniciativas, como a 1.ª Conferência sobre Formação e Carreiras realizada em 1997, e de alguns sinais positivos, como o aparecimento de novos modelos e ofertas formativas (concretizadas no ensino superior e, infelizmente, adiadas na reforma do ensino secundário), a verdade é que o panorama global da formação na área BAD em Portugal não registou significativas melhorias nos últimos anos.A repetição acrítica, ainda que com maiores ou menores retoques cosméticos, do modelo instituído há 20 anos pelos Cursos de Especialização em Ciências Documentais, em mais de uma dezena de cursos actualmente existentes, não só é completamente desadequada para a formação dos profissionais de informação, de nível superior, de que o país necessita no presente e para o futuro, como irá certamente contribuir para um aumento do desemprego entre os jovens profissionais. Ao mesmo tempo, a publicação do despacho 5122/2002, aprovando os cursos promovidos pela Associação para o ingresso nas carreiras de técnicos profissionais na administração pública, constituindo uma resposta imediata e adequada às carências de há muito existentes, não pode fazer esquecer a necessidade de integrar a formação inicial de técnicos profissionais nos sistemas de ensino "oficial".Por tudo isto, os temas relacionados com a formação devem estar no centro da reflexão dos profissionais de informação portugueses.Os artigos publicados nestes Cadernos abordam vários aspectos desta problemática, desde o papel das associações profissionais na promoção e certificação da qualidade da formação, até à utilização de novos modelos formativos, mas ficam longe de esgotar o conjunto dos aspectos sobre os quais importa reflectir e intervir.Ao dedicar o presente número dos Cadernos BAD à formação profissional, esperamos que eles possam constituir um estímulo à realização de um intenso debate que deverá culminar no 8.º Congresso.

The third stage revealed a various quality of motor eidolons.
Damped Lyman-alpha Absorbers in Cosmological SPH Simulations: the "metallicity problem"

description: We study the distribution of star formation rate (SFR) and metallicity of damped Lyman-alpha absorbers (DLAs) using cosmological smoothed particle hydrodynamics (SPH) simulations of the Lambda cold dark matter model. Our simulations include a phenomenological model for feedback by galactic winds which allows us to examine the effect of galactic outflows on the distribution of SFR and metallicity of DLAs. For models with strong galactic winds, we obtain good agreement with recent observations with respect to total neutral hydrogen mass density, N_HI column-density distribution, abundance of DLAs, and for the distribution of SFR in DLAs. However, we also find that the median metallicity of simulated DLAs is higher than the values typically observed by nearly an order of magnitude. This discrepancy with observations could be due to shortcomings in the treatment of the supernova feedback or the multiphase structure of the gas in our current simulations. Recent observations by Wolfe et al. (2003a,b) seem to point to the same problem; i.e. the observed DLA metallicities are much lower than those expected from the (either observed or simulated) DLA star formation rates, a puzzle that has been known as the ``missing metals'' problem for the globally averaged quantities.

description: We predict the masses of the lowlying $B_c$ mesons with $J^P = 0^-,\,1^-,\,0^+,\,1^+,\,2^+$, using a flavor dependent interaction pattern which gives an unified successful description of the light, heavy-light and heavy mesons and is also appliable to the radial excited heavy mesons. The errors are controlled carefully. With the errors from the RL approximation subduced, our predictions are consistent with the lQCD and quark model results, which supports strongly that the flavor dependent interaction pattern is reasonable. Our predictions provide significant guides to the experiment search of the $B_c$ mesons.

Isotropic cosmic birefringence from an oscillating axion-like field

description: We propose a new mechanism for isotropic cosmic birefringence with an axion-like field that rapidly oscillates during the recombination epoch. In conventional models, the field oscillation during the recombination epoch leads to a cancellation of the birefringence effect and significantly suppresses the EB spectrum of the cosmic microwave background (CMB) polarization. By introducing an asymmetric potential to the axion, this cancellation becomes incomplete, and a substantial EB spectrum can be produced. This mechanism also results in a washout of the EE spectrum, which can be probed in future CMB observations. Our findings suggest the possibility that an axion-like field responsible for isotropic cosmic birefringence can also account for a significant fraction of dark matter.

description: We investigate the accretion-driven growth of supermassive black holes in the low-redshift Universe using 23,000 ``Type 2'' AGN and the complete sample of 123,000 galaxies in the SDSS from which they were drawn. We use the stellar velocity dispersions of the early type galaxies and AGN hosts to estimate their black hole masses and we use the AGN [OIII]5007 emission line luminosities to estimate black hole accretion rates. We find that most present-day accretion occurs onto black holes with masses < 10E8 Msun that reside in moderately massive galaxies (M ~ 10E10 to 10E11.5 Msun) with high stellar densities (~10E8.5 to 10E9.5 Msun/kpc^2) and young stellar populations. The volume-averaged accretion rates of low mass black holes (<10E7.5 Msun) imply that this population is growing on a timescale that is comparable to the age of the Universe. Around half this growth takes place in AGN that are radiating within a factor of five of the Eddington luminosity. Such systems are rare, making up only 0.2% of the low mass black hole population at the present day. The rest of the growth occurs in lower luminosity AGN. The growth timescale is more than two orders of magnitude longer for the population of the most massive black holes in our sample. The volume averaged ratio of star formation to black hole accretion in bulge-dominated galaxies is ~1000, in remarkable agreement with the observed ratio of stellar mass to black hole mass in nearby galaxy bulges. We conclude: a) that bulge formation and black hole formation are tightly coupled, even in present-day galaxies; and b) that the evolution of the AGN luminosity function documented in recent optical and x-ray surveys is driven by a decrease in the characteristic mass scale of accreting black holes.

description: The positioning accuracy of the mobile laser scanning (MLS) system can reach the level of centimeter under the conditions where GPS works normally. However, in GPS-denied environments this accuracy can be reduced to the decimeter or even the meter level because the observation mode errors and the boresight alignment errors of MLS cannot be calibrated or corrected by the GPS signal. To bridge this research gap, this paper proposes a novel technique that appropriately incorporates the robust weight total least squares (RWTLS) and the full information maximum likelihood optimal estimation (FIMLOE) to improve the positioning accuracy of the MLS system under GPS-denied environment. First of all, the coordinate transformation relationship and the observation parameters vector of MLS system are established. Secondly, the RWTLS algorithm is used to correct the 3D point observation model; then the uncertainty propagation parameter vector and the boresight alignment errors between the laser scanner frame and the IMU frame are calibrated by FIMLOE. Lastly, experimental investigation in indoor scenarios was performed to evaluate the effectiveness of the proposed method. The experimental results demonstrate that the proposed method is able to significantly improve the positioning accuracy of an MLS system in GPS-denied environments.

description: We study the quantum Rabi model for a two-level system coupled to a quantized cavity mode under periodic modulation of the cavity-dipole coupling in the ultrastrong coupling regime, leading to rich Floquet states. As an application of the theory, we show how purely mechanical driving can produce real photons, depending on the strength and frequency of the periodic coupling rate.

description: The Kitaev chain can be engineered within a quantum dot-superconductor array, hosting Majorana zero modes at fine-tuned sweet spots. In this work, we propose and simulate the occurrence of Rabi and Ramsey oscillations to feasibly construct a minimal Majorana qubit in the quantum dot setup. Our real-time results incorporate realistic effects, e.g., charge noise and leakage, reflecting the latest experimental progress. We demonstrate that Majorana qubits with larger energy gaps exhibit significantly enhanced performance -- longer dephasing times, higher quality factors, reduced leakage probabilities, and improved visibilities -- compared to those with smaller gaps and with conventional quantum dot-based charge qubits. We introduce a method for reading out Majorana qubits via quantum capacitance measurements. Our work paves the way for future experiments on realizing Majorana qubits in quantum dot-superconductor arrays.

description: Sugar-sweetened beverages (SSBs) are the highest source of added sugars in the Canadian diet (Government of Canada, 2018a), and university-aged adults are the demographic that consume the highest amounts of SSBs (Di Sebastiano et al., 2020). SSB intake of UBC students is concerning due to their negative impact on health. One way that UBC organizations are addressing SSB intake is by promoting tap water. UBC Wellbeing launched the Healthy Beverage Initiative (HBI) and related UBC Drinks Tap Water campaign to promote tap water consumption and reduce SSB intake. FNH 473 Group 7 conducted a Tap Water Study in collaboration with UBC Social Ecological Economic Development (SEEDS) Sustainability Program, UBC Food Services, and UBC Wellbeing. The goal was to gain insight into UBC students’ beverage choices and perceptions, both on- and off-campus, to inform UBC’s tap water campaign. Short-term objectives include providing survey results on beverage consumption habits of UBC students. Medium- and long-term objectives include this study being used to inform UBC programs and policies to increase tap water consumption and reduce SSB intake. Survey results consisted of 161 complete responses, the majority of whom reported drinking water daily, and many participants (n=70) reported choosing tap/fountain water. 10% of survey participants did not believe their tap water was safe to drink at home, while 23% of survey participants did not believe that tap water was safe to drink at UBC. When asked to select the main factors that influence drink choices, taste and nutrition were revealed as the top factors influencing their intake. To evaluate the project process, quantitative indicators include the number of survey channels used and the number of survey responses received (n=161). The five channels used included Facebook and WeChat group chats, Canvas class emails, Instagram, class announcements, and peers of team members. Qualitative process indicators include whether the survey results were useful for the community partners and whether they gained knowledge from our findings. To evaluate the project outcomes, two indicators: (1) whether the findings were used in future interventions and (2) whether the findings helped achieve a 50% reduction in SSB consumption on the UBC Vancouver campus, which can be used in the future to assess the survey impact. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC.

description: The work concerns the quasielastic charged current neutrino-neutron and antineutrino-proton interactions. Single, double, and triple spin asymmetries are computed and analyzed. The spin asymmetries are sensitive to the axial form factor of the nucleon. In particular, the target-recoil double spin asymmetry and the lepton-target-recoil triple spin asymmetry depend strongly on the axial form factor of the nucleon. Indeed, the sign and shape of these components depend on the axial mass parameter. All the asymmetries, except the lepton polarization, are observables well suited to study the nonstandard interactions described by the second class current contribution.

description: To each natural deformation quantization on a Poisson manifold M we associate a Poisson morphism from the formal neighborhood of the zero section of the cotangent bundle to M to the formal neighborhood of the diagonal of the product M x M~, where M~ is a copy of M with the opposite Poisson structure. We call it dequantization of the natural deformation quantization. Then we "dequantize" Fedosov's quantization.

description: This report attempts to identify the contributions of technology and weather to soybean yield variation for the period 1965 to 1979 in the Corn Belt Region. Technology variables included were genetic improvement, herbicides, and row-width. A pooled cross-sectional time-series data base was used to estimate regression parameters for herbicides and other variables. A marginal private benefit/cost return of $2.3 per dollar of herbicide cost was estimated for additional land treated with herbicides.
The formation of bulges and black holes: lessons from a census of active galaxies in the SDSS

description: We examine the relationship between galaxies, supermassive black holes and AGN using a sample of 22,000 narrow-emission-line AGN drawn from a a sample of 122,000 galaxies from the Sloan Digital Sky Survey. We have studied how AGN host properties compare with those of normal galaxies and how they depend on the luminosity of the active nucleus. We find that AGN reside in massive galaxies and have distributions of sizes and concentrations that are similar to those of the early-type galaxies in our sample. The host galaxies of low-luminosity AGN have stellar populations similar to normal early-types. The hosts of high-luminosity AGN have much younger mean stellar ages and a significant fraction have experienced recent starbursts. High-luminosity AGN are also found in lower density environments. We use the stellar velocity dispersions of the AGN hosts to estimate black hole masses and their [OIII]$λ$5007 emission line luminosities to estimate black hole accretion rates. We find that the volume averaged ratio of star formation to black hole accretion is ~1000, in remarkable agreement with the observed ratio of stellar mass to black hole mass in nearby bulges. Our estimated accretion rates imply that low mass black holes are growing on a timescale that is comparable to the age of the Universe. The growth timescale increases by more than an order of magnitude for the most massive black holes in our sample. We conclude that the evolution of the AGN luminosity function is driven by a decrease in the characteristic mass scale of actively accreting black holes.

Compactness peaks: An astrophysical interpretation of the mass distribution of merging binary black holes

description: With the growing number of detections of binary black hole mergers, we are beginning to probe structure in the distribution of masses. A recent study by Schneider et al. proposes that isolated binary evolution of stripped stars naturally gives rise to the peaks at chirp masses $\sim 8 M_\odot$, $14 M_\odot$ in the chirp mass distribution and explains the dearth of black holes between $\approx 10-12 M_\odot$ in chirp mass. The gap in chirp mass results from an apparent gap in the component mass distribution between $m_1, m_2 \approx 10-15 M_\odot$ and the specific pairing of these black holes. This component mass gap results from the variation in core compactness of the progenitor, where a drop in compactness of Carbon-Oxygen core mass will no longer form black holes from core collapse. We develop a population model motivated by this scenario to probe the structure of the component mass distribution of binary black holes consisting of two populations: 1) two peak components to represent black holes formed in the compactness peaks, and 2) a powerlaw component to account for any polluting events, these are binaries that may have formed from different channels (e.g. dynamical). We perform hierarchical Bayesian inference to analyse the events from the third gravitational-wave transient catalogue (GWTC-3) with this model. We find that there is a preference for the lower mass peak to drop off sharply at $\sim 11 M_\odot$ and the upper mass peak to turn on at $\sim 13 M_\odot$, in line with predictions from Schneider et al. However, there is no clear evidence for a gap. We also find mild support for the two populations to have different spin distributions. In addition to these population results, we highlight observed events of interest that differ from the expected population distribution of compact objects formed from stripped stars.
