description: We report our theoretical results on the emergence of a nonlinear frequency-asymmetric optical response characteristic of chiral crystal systems with neither spatial inversion symmetry nor mirror symmetry. Based on the group theoretical analysis, we show that the chirality-related second-order nonlinear optical response occurs for two different input frequencies when the low-energy model Hamiltonian includes a time-reversal-even pseudoscalar quantity, i.e., the electric toroidal monopole. We demonstrate its emergence by investigating a fundamental microscopic model with the chiral-type antisymmetric spin--orbit interaction on a simple cubic lattice. By analyzing the behavior of nonlinear optical conductivity based on the Kubo formula, we find that the response is largely enhanced when one of the frequencies is set to zero and the other is set to a resonant frequency. We also discuss the relaxation time dependence of the response.

description: Актуальность работы обусловлена определением причинноследственных связей, обуславливающих ценовую динамику в различных сегментах сырьевого и потребительского рынков с учётом макроэкономических показателей, которые являются взаимосвязанной системой с очень сложными отношениями и значительным количеством факторов, вызывающих изменение котировок. Объектом анализа является ценовая динамика на нефть и лесоматериалы на европейском рынке. Для анализа сформированы выборки годовых цен на древесины, пиломатериалы, фанеру и целлюлозу с 1985 г. по 2015 г. Проведены корреляционный и регрессионный анализы цен на лесопромышленную продукцию и цен на нефть. Корреляционный анализ показал наличие однонаправленных связей средней силы между исследуемыми выборками. Регрессионный анализ позволил построить уравнения зависимости цен лесных материалов от цен на нефть. Следующие исследования авторы планируют посвятить разработке многофакторных пространственных и временных моделей российского и мирового рынка лесопромышленной продукции.

description: False Creek is an inlet located south of Downtown Vancouver that serves as a crucial spawning ground for Pacific Herring (Clupea pallasii). These fish are a vital component of the Salish Sea’s aquatic food web, as they are relied upon by seals, seabirds, and other species. Historically, the herring have spawned in False Creek’s eelgrass and macroalgae. However, False Creek has undergone significant changes from tidal flats to marinas and housing. As a result, there are no longer any natural spawning grounds for the herring in False Creek. This has led to egg deposits on toxic creosote wood pilings at the wharf. To address this issue, Squamish Streamkeepers have used non-toxic plastic around the wood pilings and deployed net panels to mimic spawning habitat. Since 2019, a UBC student team has been working with CityStudio and the City of Vancouver to support Squamish Streamkeepers’ efforts. The primary objective of this project is to closely monitor the 2023 herring spawn and assess how water abiotic conditions predict a spawn event at Fisherman’s Wharf.

description: For non-empty sets X we define notions of distance and pseudo metric with values in a partially ordered set that has a smallest element $θ$. If $h_X$ is a distance in $X$ (respectively, a pseudo metric in $X$), then the pair $(X,h_X)$ is called a distance (respectively, a pseudo metric) space. If $(T,h_T)$ and $(X,h_X)$ are pseudo metric spaces, $(Y,h_Y)$ is a distance space, and $H(T,X)$ is a class of Lipschitz mappings $f\colon T\to X$, for a broad family of mappings $Λ\colon H (T,X)\to Y$, we obtain a sharp inequality that estimates the deviation $h_Y(Λf(\cdot),Λf(t))$ in terms of the function $h_T(\cdot, t)$. We also show that many known estimates of such kind are contained in our general result.

description: The most significant danger to animals around the world is the loss of their habitat, which is occurring due to the growth and expansion of the human population. The construction of new buildings such as the Brock Commons Residence at the University of British Columbia (UBC)are occurring near a mixed forest area can disrupt and fragment natural habitats, posing a threat to biodiversity for the local wildlife. This study seeks to evaluate the impact of human activities on animals and their habitats at the UBC Farm. To achieve this, we analyze camera trap data to investigate the spatial distribution of mammals and study the interactions between different species and behavioural trends through the changes in population. The primary aim of the research is to develop a more comprehensive understanding of how human actions affect animals in this particular area. Camera trap data has been collected since 2019. The camera trap data was sorted into different categories based on habitat and whether it was a market or non-market day. An occupancy model was then employed to make predictions about the likelihood of occurrence. Our findings revealed, coyotes were predominantly detected in the Annual Production Areas which is an area where human activities occur such as farming and market days, whereas squirrels and raccoons were more commonly found in the Mixed Forest Area. Furthermore, the study revealed that the interactions between coyotes and their prey were consistent across different habitats, however, there was no observable impact of human presence on mammal behaviour. Despite this outcome, our research findings indicate that mammal habitats are affected by human activities such as construction projects. The report puts forth several recommendations aimed at enhancing future research to produce definitive findings on mammal behaviour trends. These include facilitating access to the photo database to enable the use of machine learning algorithms for animal tagging, gathering covariate data on external factors that affect mammal behaviour, exploring the impact of noise pollution on mammal behaviour, and increasing the volume of data to improve detection rates for less frequently observed animals. To achieve these goals, the report suggests deploying additional camera traps, positioning them strategically, and extending their observation period. The study has the potential to enhance ecological and environmental sustainability at UBC, and hope that the insights gained can help shape development projects at UBC to minimize their impact on local biodiversity.

description: To reduce the reliance on high-definition (HD) maps, a growing trend in autonomous driving is leveraging onboard sensors to generate vectorized maps online. However, current methods are mostly constrained by processing only single-frame inputs, which hampers their robustness and effectiveness in complex scenarios. To overcome this problem, we propose an online map construction system that exploits the long-term temporal information to build a consistent vectorized map. First, the system efficiently fuses all historical road marking detections from an off-the-shelf network into a semantic voxel map, which is implemented using a hashing-based strategy to exploit the sparsity of road elements. Then reliable voxels are found by examining the fused information and incrementally clustered into an instance-level representation of road markings. Finally, the system incorporates domain knowledge to estimate the geometric and topological structures of roads, which can be directly consumed by the planning and control (PnC) module. Through experiments conducted in complicated urban environments, we have demonstrated that the output of our system is more consistent and accurate than the network output by a large margin and can be effectively used in a closed-loop autonomous driving system.

description: High-$T_c$ cuprates are characterized by strong spin fluctuations, which give rise to antiferromagnetic and pseudogap phases and may be key to the high superconducting critical temperatures observed in these materials. Experimental studies have revealed significant changes in the Hall coefficient $R_H$ across these phases, a phenomenon closely related to both spin fluctuations and changes in the Fermi surface morphology. Using the perturbation correction to Gaussian approximation (PCGA), we investigate the two-dimensional(2D) square-lattice single-band Hubbard model and obtain the self-energy with a finite imaginary part due to scattering. We calculate the density dependence of the Hall number $n_H=1/(qR_H)$. For small hole (or electron) doping $p$ (or $x$), our numerical results show that $n_H$ transitions from $p$ to $1+p$ for hole-doped systems, and from $-x$ to $1-x$ for electron-doped systems -- both in agreement with experimental findings. Furthermore, we discuss the correlation between phase boundaries and the observed peculiar changes in the Hall number.

Résumé :

L’observatoire des cultures écrites anciennes Biblissima+ est une infrastructure numérique de recherche fondamentale et de service consacrée à l’histoire de la transmission des textes anciens, de l’Antiquité à la Renaissance en Orient comme en Occident. Faisant partie des équipements structurants pour la recherche ÉquipEx+ sélectionnés en 2020 dans le cadre des investissements d’avenir du plan France 2030, il est construit autour d’une vision de l’innovation et de la transition numérique en SHS plus tournée vers l’identification de domaine prometteurs et l’encouragement des communautés à adopter les technologies qu’à la prise en compte des impacts énergétiques ou à la sobriété technologique volontaire. A l’heure où la continuation de l’infrastructure Biblissima au-delà du financement Equipex est à l’étude, intégrer une approche “Low Tech” à la réflexion paraît incontournable afin de construire un projet de long terme.

La séance sera ainsi organisée en deux temps : une présentation générale de l’infrastructure au prisme des démarches Low Tech et une mise en perspective sur le cas spécifique de l’intelligence artificielle pour la reconnaissance des formes et des écritures manuscrites qui fait partie de l’un des 7 pôles d’expertise de Biblissima+.

Analyzing Bovine Steps to Predict Estrus Events using Machine Learning Techniques
Creators: name: Jonnatan, Livia
Publisher: name: The University of British Columbia
Year: 2023

description: The steady growth of the world population also means the growing demand for food. Farms across the world aim to increase profitability and be more efficient, including dairy farms. In order to achieve that, farmers must be able to make the right decisions regarding when and how to use their resources. For dairy farmers, they are interested in knowing estrus events, which is an ideal time to inseminate and treat cows. Farmers traditionally use their expertise and experience to make these decisions, but this takes time and is hard to generalize and scale to larger herds. Nowadays, there are deployments of animal activity sensors, which help farmers gain more insights of their farms. This opens an opportunity to utilize machine learning algorithms to timely and accurately detect estrus events. The aim of this study is to analyze step count data from 332 cows to be used as a predictor of estrus events using several supervised machine learning algorithms, such as classification tree, K-Nearest Neighbors (KNN), Logistic Regression, and Linear Discriminant Analysis (LDA). The results reveal high accuracy, but low precision, recall, and F1-score. Although during estrus cycles there were increased physical activity for some cows, this is not generalizable for all cows. Using only the step count data has been shown to be insufficient to accurately predict estrus cycles.

description: Improving the quality of underwater images is essential for advancing marine research and technology. This work introduces a sparsity-driven interpretable neural network (SINET) for the underwater image enhancement (UIE) task. Unlike pure deep learning methods, our network architecture is based on a novel channel-specific convolutional sparse coding (CCSC) model, ensuring good interpretability of the underlying image enhancement process. The key feature of SINET is that it estimates the salient features from the three color channels using three sparse feature estimation blocks (SFEBs). The architecture of SFEB is designed by unrolling an iterative algorithm for solving the $\ell_1$ regularized convolutional sparse coding (CSC) problem. Our experiments show that SINET surpasses state-of-the-art PSNR value by $1.05$ dB with $3873$ times lower computational complexity.

description: Though control algorithms for multirotor Unmanned Air Vehicle (UAV) are well understood, the configuration, parameter estimation, and tuning of flight control algorithms takes quite some time and resources. In previous work, we have shown that it is possible to identify the control effectiveness and motor dynamics of a multirotor fast enough for it to recover to a stable hover after being thrown 4 meters in the air. In this paper, we extend this to include estimation of the position of the Inertial Measurement Unit (IMU) relative to the Center of Gravity (CoG), estimation of the IMU rotation, the thrust direction of all motors and the optimal combined thrust direction. In order to guarantee a correct IMU position estimation, two prior throw-and-catches of the vehicle with spin around different axes are required. For these throws, a height as low as 1 meter is sufficient. Quadrotor flight experimentation confirms the efficacy of the approach, and a simulation shows its applicability to fully-actuated crafts with multiple possible hover orientations.

description: The analysis of experimental results with Python often requires writing many code scripts which all need access to the same set of functions. In a common field of research, this set will be nearly the same for many users. The qspec Python package was developed to provide functions for physical formulas, simulations and data analysis routines widely used in laser spectroscopy and related fields. Most functions are compatible with numpy arrays, enabling fast calculations with large samples of data. A multidimensional linear regression algorithm enables a King plot analyses over multiple atomic transitions. A modular framework for constructing lineshape models can be used to fit large sets of spectroscopy data. A simulation module within the package provides user-friendly methods to simulate the coherent time-evolution of atoms in electro-magnetic fields without the need to explicitly derive a Hamiltonian.

description: Although Telegram is currently one of the most popular instant messaging apps in the world, previous studies have mainly focused on analysing discussions on specific angles and topics. In this paper, we present a broad analysis of publicly accessible groups that cover a wide range of discussions, including Education, Erotic, Politics, and Cryptocurrencies. How do people interact with different topic groups? Is there any common or peculiar behaviour? We engineer and offer an open-source tool to automate the collection of messages from Telegram groups, a non-straightforward problem. We use it to collect more than 51 million messages from 669 groups. Here, we present a first-of-its-kind, per-topic analysis, contrasting the users' activity patterns from different angles -- the language, the presence of bots, the type and volume of shared media content, links to external platforms, etc. Our results confirm some anecdotal evidence, e.g., indications of spamming behaviour, and unveil some unexpected findings, e.g., the different sharing patterns of video and message length in groups of different topics.

description: Matrix completion tackles the task of predicting missing values in a low-rank matrix based on a sparse set of observed entries. It is often assumed that the observation pattern is generated uniformly at random or has a very specific structure tuned to a given algorithm. There is still a gap in our understanding when it comes to arbitrary sampling patterns. Given an arbitrary sampling pattern, we introduce a matrix completion algorithm based on network flows in the bipartite graph induced by the observation pattern. For additive matrices, the particular flow we used is the electrical flow and we establish error upper bounds customized to each entry as a function of the observation set, along with matching minimax lower bounds. Our results show that the minimax squared error for recovery of a particular entry in the matrix is proportional to the effective resistance of the corresponding edge in the graph. Furthermore, we show that our estimator is equivalent to the least squares estimator. We apply our estimator to the two-way fixed effects model and show that it enables us to accurately infer individual causal effects and the unit-specific and time-specific confounders. For rank-$1$ matrices, we use edge-disjoint paths to form an estimator that achieves minimax optimal estimation when the sampling is sufficiently dense. Our discovery introduces a new family of estimators parametrized by network flows, which provide a fine-grained and intuitive understanding of the impact of the given sampling pattern on the relative difficulty of estimation at an entry-specific level. This graph-based approach allows us to quantify the inherent complexity of matrix completion for individual entries, rather than relying solely on global measures of performance.

description: A successful theory of star formation should predict the number of objects as a function of their mass produced through star-forming events. Previous studies in star-forming regions and the solar neighborhood identify a mass function increasing from the hydrogen-burning limit down to about 10 M$_{J}$. Theory predicts a limit to the fragmentation process, providing a natural turnover in the mass function down to the opacity limit of turbulent fragmentation thought to be near 1-10 M$_{J}$. Programs to date have not been sensitive enough to probe the hypothesized opacity limit of fragmentation. We present the first identification of a turnover in the initial mass function below 12 M$_{J}$ within NGC 2024, a young star-forming region. With JWST/NIRCam deep exposures across 0.7-5 $μ$m, we identified several free floating objects down to roughly 3 M$_{J}$ with sensitivity to 0.5 M$_{J}$. We present evidence for a double power law model increasing from about 60 M$_{J}$ to roughly 12 M$_{J}$, consistent with previous studies, followed by a decrease down to 0.5 M$_{J}$. Our results support the predictions of star and brown dwarf formation theory, identifying the theoretical turnover in the mass function and suggest the fundamental limit of turbulent fragmentation near 3 M$_{J}$.

description: Compact optical atomic clocks have become increasingly important in field applications and clock networks. Systems based on Ramsey-Borde interferometry (RBI) with a thermal atomic beam seem promising to fill a technology gap in optical atomic clocks, as they offer higher stability than optical vapour cell clocks while being less complex than cold atomic clocks. Here, we demonstrate RBI with strontium atoms, utilizing the narrow 1S0 -> 3P1 intercombination line at 689 nm, yielding a 60 kHz broad spectral feature. The obtained Ramsey fringes for varying laser power are analyzed and compared with a numerical model. The 1S0 -> 1P1 transition at 461 nm is used for fluorescence detection. Analyzing the slope of the RBI signal and the fluorescence detection noise yields an estimated short-term stability of 4x10-14 / sqrt{tau}. We present our experimental setup in detail, including the atomic beam source, frequency-modulation spectroscopy to lock the 461 nm laser, laser power stabilization and the high-finesse cavity pre-stabilization of the 689 nm laser. Our system serves as a ground testbed for future clock systems in mobile and space applications.
