description: With the recent boom of video-based social platforms (e.g., YouTube and TikTok), video retrieval using sentence queries has become an important demand and attracts increasing research attention. Despite the decent performance, existing text-video retrieval models in vision and language communities are impractical for large-scale Web search because they adopt brute-force search based on high-dimensional embeddings. To improve efficiency, Web search engines widely apply vector compression libraries (e.g., FAISS) to post-process the learned embeddings. Unfortunately, separate compression from feature encoding degrades the robustness of representations and incurs performance decay. To pursue a better balance between performance and efficiency, we propose the first quantized representation learning method for cross-view video retrieval, namely Hybrid Contrastive Quantization (HCQ). Specifically, HCQ learns both coarse-grained and fine-grained quantizations with transformers, which provide complementary understandings for texts and videos and preserve comprehensive semantic information. By performing Asymmetric-Quantized Contrastive Learning (AQ-CL) across views, HCQ aligns texts and videos at coarse-grained and multiple fine-grained levels. This hybrid-grained learning strategy serves as strong supervision on the cross-view video quantization model, where contrastive learning at different levels can be mutually promoted. Extensive experiments on three Web video benchmark datasets demonstrate that HCQ achieves competitive performance with state-of-the-art non-compressed retrieval methods while showing high efficiency in storage and computation. Code and configurations are available at https://github.com/gimpong/WWW22-HCQ.

title: Student Self-Assessment and Student Ratings of Teacher Rapport in Secondary Student Course Ratings
Creators: name: Roe, John Wilford
Publisher: name: Utah State University
Year: 2010

description: This study involved administering two rating forms (student self-rating on commitment and student rating of teacher rapport) to approximately 1,400 secondary students taught by 12 different teachers at two different high school Latter-day Saint (LDS) released time seminaries along the Wasatch Front in Utah. Seminaries and Institutes of Religion (S&I) function within the Church Educational System (CES) of the LDS Church, providing religious education for secondary students between the ages of 14-18. The purpose of this study was to explore relationships between student, teacher, and course characteristics on student ratings of teacher rapport and to explore a possible relationship between student self-assessments on their own commitment to learning with student ratings on their rapport with their teacher. Evidence suggests that teacher characteristics such as the teacher's age and experience have little to no impact on student ratings of teacher rapport. Female students tended to rate their teacher more favorably on rapport than male students, although practical significance was minimal. Younger students reported greater interest in seminary and higher-grade expectancy. They also tended to rate themselves higher on commitment. A statistically significant difference was found for teacher rapport scores between two groups based on the order of test administration. Group 1--self-first (student self-rating before student rating of teacher rapport) reported higher levels of rapport than group 2--comparison (student rating of teacher rapport prior to student self-rating). Students tended to rate their teacher more favorably after completing a self-rating on commitment. Practical significance between study groups was minimal because findings were small. Further research is suggested based on these findings to seek more understanding regarding the relationship between student self-evaluations and student ratings of their teacher.

Glissile dislocations with transient cores in silicon

description: We report an unexpected characteristic of dislocation cores in silicon. Using first-principles calculations, we show that all the stable core configurations for a non-dissociated 60$^\circ$ dislocation are sessile. The only glissile configuration, previously obtained by nucleation from surfaces, surprinsingly corresponds to an unstable core. As a result, the 60$^\circ$ dislocation motion is solely driven by stress, with no thermal activation. We predict that this original feature could be relevant in situations for which large stresses occur, such as mechanical deformation at room temperature. Our work also suggests that post-mortem observations of stable dislocations could be misleading, and that mobile unstable dislocation cores should be taken into account in theoretical investigations.

description: Can active forces be exploited to drive the consistent collapse of an active polymer into a folded structure? In this paper we introduce and perform numerical simulations of a simple model of active colloidal folders, and show that a judicious inclusion of active forces into a stiff colloidal chain can generate designable and reconfigurable two dimensional folded structures. The key feature is to organize the forces perpendicular to the chain backbone according to specific patterns (sequences). We characterize the physical properties of this model and perform, using a number of numerical techniques, an in-depth statistical analysis of structure and dynamics of the emerging conformations. We discovered a number of interesting features, including the existence of a direct correspondence between the sequence of the active forces and the structure of folded conformations, and we discover the existence of an ensemble of highly mobile compact structures capable of moving from conformation to conformation. Finally, akin to protein design problems, we discuss a method that is capable of designing specific target folds by sampling over sequences of active forces.

description: The article shows that the science-intensive industry development should be carried out through programs that combine a set of projects aimed at achieving a general goal in the face of common restrictions. However, the existence of a set of project characteristics taken into account in the formation of program content leads to the formulation of the multi-objective optimization task. As a solution, it is proposed to use the bacterial optimization algorithm modified by introducing fuzzy elements.

description: We analyze the topological properties of the set of functions that can be implemented by neural networks of a fixed size. Surprisingly, this set has many undesirable properties. It is highly non-convex, except possibly for a few exotic activation functions. Moreover, the set is not closed with respect to Lp-norms, 00, it is, regardless of the size of ε, usually not possible to find weights w1,w2 close together such that each fi is realized by a neural network with weights wi. Overall, our findings identify potential causes for issues in the training procedure of deep learning such as no guaranteed convergence, explosion of parameters, and slow convergence.
Transferal of postural and emotional adaptation from virtual to real heights
Creators: name: Zhang, Xiangwei
Publisher: name: University of British Columbia
Year: 2025

description: This study explored the adaptation and transmission of emotional state, and standing balance to repeated real postural threats after repeated exposure to a virtual postural threat during quiet standing. Specific alterations in standing balance show a stronger correlation with the emotional reaction to a perceived threat. Virtual Reality (VR) has demonstrated utility in examining postural adjustments linked to fear, anxiety, and motor control under different types of perturbations. However, whether the emotional and postural adaptations learned in VR can be transferred to real scenarios is unknown. The primary aim of this study was to examine whether emotional adaptation developed in a VR environment could successfully transfer to real-height scenarios. Additionally, the study sought to understand how such adaptation might influence participants' postural control when facing actual height-induced postural threats. By analyzing both emotional responses, standing balance and postural control across VR and real environments, this research aimed to determine the potential for VR as a training tool for enhancing balance and reducing anxiety-related reactions to heights in real-world settings. The results demonstrated clear adaptation in emotional responses among Study Group participants during their exposure to VR at HIGH heights. This emotional adaptation was observed in both groups during their second visits, with participants who had prior VR training showing a smaller change in emotional response when transitioning from REAL LOW to REAL HIGH conditions. Although not all standing balance outcomes showed significant differences, Study Group participants exhibited a smaller backward lean compared to those who had not trained in VR. These results indicate that VR can be an effective tool for eliciting and training participants' emotional responses, particularly in height-related scenarios.

title: A Multi-scale Evaluation of Pygmy Rabbit Space Use in a Managed Landscape
Creators: name: Wilson, Tammy L.
Publisher: name: Utah State University
Year: 2010

description: Habitat selection has long been viewed as a multi-scale process. Observed species responses to resource gradients are influenced by variation at the scale of the individual, population, metapopulation, and geographic range. Understanding how species interact with habitat at multiple levels presents a complete picture of an organism and is necessary for conservation of endangered species. The main goal of this dissertation is to evaluate distribution, relative abundance, and habitat selection of a rare species, the pygmy rabbit Brachylagus idahoensis, at multiple scales in order to improve management and conservation for this species. At the broadest scale, pygmy rabbit occurrence and relative abundance were modeled in the Duck Creek allotment of northern Utah using a hierarchical spatial model. Pygmy rabbits are not easily observable, and the model used two levels of indirect detection to make statistically rigorous spatial predictions. We found that the model predicted the general pattern of rabbit occurrence and abundance within the study area, and that there was spatial heterogeneity in the probability of pygmy rabbit occurrence within a study domain that was known to be occupied. The resulting model framework could be used to develop a long-term monitoring program for pygmy rabbits and other species for which hierarchically nested levels of indirect observation are collected. The mid-scale analysis evaluated pygmy rabbit home range placement and movement with respect to sagebrush removal treatments using null models based on an optimal central place foraging behavior. While placement of home-range centers did not appear to be affected by the treatments, within-home range movements were farther from treatments than expected by the null models for two rabbits (of eight), and rabbits that approached treatment edges were less likely to enter treatments than expected by chance. Rabbits are not extirpated from sites that have been treated, but the observed reluctance to enter treated patches calls for caution when conducting sagebrush removal treatments near occupied pygmy rabbit burrows. At the finest level of resolution, the spatial ecology of pygmy rabbit use of burrows was evaluated. Both the placement of burrows in general and pygmy rabbit use of burrows were clustered. While the habitat gradients experienced by each of the rabbits evaluated affected the modeled habitat selection responses, some generalities were observed. Selection of high cover suggests that pygmy rabbit use of burrows may be linked to predator avoidance behavior. Additionally, pygmy rabbit use of clustered burrows affects management actions including: habitat modeling, monitoring, and species introduction. Explicit attention to resource distribution will improve efforts to predict species responses to management actions.
Combatting bias in small medical imaging datasets with generative deep learning

description: As artificial intelligence (AI) continues to find its way into more aspects of our daily lives, addressing its potential for bias and discriminatory behaviour has become increasingly critical. While bias remains a concern in all fields of machine learning, it presents as a particularly relevant problem when working on medical imaging applications. The costly nature of scanning participants combined with the frequently unbalanced distributions in real-world health conditions make most datasets highly under sampled and unbalanced. To combat the effects of bias in small medical imaging datasets we propose employing a generative deep learning framework to synthesize additional samples of the under-represented groups. In this research we first explore how imbalances in participant age, sex, disease phenotype, and scanner manufacturer effect downstream performance of three progressively more difficult classification tasks in a small brain MRI dataset (n=1000) of people living with Multiple Sclerosis (MS): MS versus healthy control, MS phenotype, and progressor versus non-progressor classification. Our results demonstrate that for all chosen factors except for sex, downstream classification performance is significantly lower in the under-represented groups. We then created a state-of-the-art wavelet diffusion model (WDM) to synthesize additional samples conditioned on the identified sources of bias. We evaluate the performance of the generative model data by training classifiers to predict the conditioning targets on a set of fully synthetic data. The trained classifiers are then applied to a test set of real data in order to evaluate if the features present in the synthetic data are representative of real features. Lastly, we synthesize brain MRIs of the specific underrepresented groups and re-evaluate performance on the three previously defined classification tasks. Our results demonstrate that by including synthetic data, we reduce the relative gaps in performance between the majority and minority groups without harming the overall performance. This research indicates that synthetic data from generative deep learning models can be a powerful tool to combat bias if intelligently configured to synthesize new samples of underrepresented groups.

description: We report the LWFA driven X-ray sources development at ELI beamlines. ELI Gammatron beamline provides X-ray pulses of energies from 1-100 keV in betatron scheme, and up to a MeV in Compton scheme. A state-of-the-art Ti:Sa diode-pumped HAPLS laser (10-30 J, 30 fs @10 Hz) is used as a driving laser for these X-ray sources. These sources are characterized with a low divergence (< 10 mrad), small source size (few μm), short pulse duration (a few fs) and photon flux up to1010 photons per pulse. In addition, a separate Betatron X-ray source is being developed in the ELI Plasma Physics Platform (P3)that will serve as an active diagnostics of various plasma physics experiments. P3 is dedicated to laboratory astrophysics, HED physics, multi-beam experiments, warm dense matter and fundamental research. Besides the presentation of the two X-ray sources, we will also introduce a novel optical probing method with increased interferometric sensitivity for characterization of low-density gas jets. The sensitivity is achieved together with using a novel optical configuration employing multiple passes of the probe beam through the object and relay-imaging of the object between the individual passes, and a short probing beam (405 nm).

title: Greater Sage-Grouse Seasonal Ecology and Responses to Habitat Manipulations in Northern, Utah
Creators: name: Thacker, Eric T.
Publisher: name: Utah State University
Year: 2010

description: Declining greater sage-grouse populations (Centrocercus urophasianus; hereafter sage-grouse) have led to increased concern regarding the long-term stability of the species. Previous research has identified factors contributing to the observed population declines. Habitat degradation and loss have been implicated as major factors in population declines. Although much is known about sage-grouse biology, more information is needed about population responses to specific management actions. This research was conducted to document sage-grouse responses to site-specific management actions. Additionally, I evaluated sage-grouse temporal and seasonal habitat-use and the comparability of techniques used by range and wildlife managers to measure vegetation responses of habitat management. Specifically, I evaluated 1) whether chemical analysis (gas chromatography) of sage-grouse fecal pellets could identify sagebrush species in sage-grouse winter diets, 2) the comparability of the line-point intercept and Daubenmire canopy cover methods for estimating canopy cover, 3) the response of sage-grouse broods to prescribed burns in a high elevation sagebrush community in northeastern Utah, and 4) the vegetation and insect characteristics of sites used by sage-grouse broods during a 24-hour period. I was able to determine wintering sage-grouse diets using gas chromatography by analyzing fecal pellets. This research also confirmed that black sagebrush (Artemisia nova) was an important component of sage-grouse winter diets in western Box Elder County and Parker Mountain populations. The line-point intercept and Daubenmire methods for estimating canopy cover are not comparable. Sage-grouse broods selected small (~ 25 ha) patchy prescribed burns in high elevation mountain big sagebrush (A. tridentata vaseyana) communities in northeastern Utah. Sage-grouse brood-site use in northwestern Utah did not differ during the diurnal hours, but nocturnal roost sites were characterized by shorter statured shrubs and more bare ground when compared to midday sites.

description: We consider the set of all spacelike embeddings of the circle S1 into a spacetime R1 × S1 with a metric globally conformal to the Minkowski metric. We identify this set and the group of conformal isometries of this spacetime as quotients of semidirect products involving diffeomorphism groups and give a transitive action of the conformal group on the set of spacelike embeddings. We provide results showing that the group of conformal isometries is a topological group and that its action on the set of spacelike embeddings is continuous. Finally, we point out some directions for future research.

Two-dimensional ferroelectricity induced by octahedral rotation distortion in perovskite oxides

description: Two-dimensional (2D) ferroelectricity has attracted extensive attention since its discovery in the monolayers of van der Waals materials. Here we show that 2D ferroelectricity induced by octahedral rotation distortion is widely present in the perovskite bilayer system through first-principles calculations. The perovskite tolerance factor plays a crucial role in the lattice dynamics and ground-state structure of the perovskite monolayers and bilayers, thus providing an important indicator for screening this hybrid improper ferroelectricity. Generally, the ferroelectric switching via an orthorhombic twin state has the lowest energy barrier. Epitaxial strain can effectively tune the ferroelectric polarization and ferroelectric switching by changing the amplitude of octahedral rotation and tilt distortion. The increasing compressive strain causes a polar to nonpolar phase transition by suppressing the tilt distortion. The cooperative effect of octahedral distortion at the interface with the substrate can reduce the energy barrier of the reversing rotation mode and can even change the lowest-energy ferroelectric switching path.

title: Re-imagining Transnational Identities in Norma Cantú's Canícula and Jhumpa Lahiri's The Namesake
Creators: name: Paudyal, Binod
Publisher: name: Utah State University
Year: 2010

description: This thesis examines Norma Cantú's Canícula and Jhumpa Lahiri's The Namesake from the framework of transnationalism characterized by migration, transculturation, and hybridity. With the application of postcolonial theories, related to identity and space, it identifies the space between different cultural and national borders, as liminal space in which the immigrant characters diverge and intersect, ultimately constituting a form of hybrid and transnational identities. While most immigrant writers still explore the themes of complexities of lifestyles, cultural dislocation, and the conflicts of assimilation, and portray their characters as torn between respecting their family traditions and an Americanized way of life, my reading of these two immigrant writers goes beyond this conventional wisdom about the alienated postcolonial subject. Through a comparative analysis of the major themes in Canícula and The Namesake that center on issues of cultural and national border crossing, this thesis contends that Cantú and Lahiri attempt to construct transnational identities for immigrants, while locating and stabilizing them in the United States. Given the nature of the mobility of people and their cultures across nations, both writers deterritorialize the definite national and cultural identities suggesting that individuals cannot confine themselves within the narrow concept of national and cultural boundaries in this globalized world. A comparison between the transnational identity of the 1950s in Canícula and that of the 1970s through the twenty-first century in The Namesake demonstrates that identities are becoming more transnational and global due to the development of technologies, transportation, and global connections between people. In this regard, this thesis attempts to offer a re-vision of the contemporary United States not as a static and insular territory but a participant in transnational relations.
title: Effects of Submergence in Montana Flumes

description: As part of a continued research project for the Utah Water Research Laboratory and the State of Utah, a study of flow measurement devices is being conducted throughout the state. Initially the project included only measurement devices associated with high-risk dams, but has since been broadened to any measurement structure of interest for water users in the state. The physical dimensions, relative elevations, and flow accuracy were documented for each included device. After visiting sixteen sites, it was found that fourteen of the measuring devices had incorrect geometries. Of these fourteen, thirteen of them were originally Parshall flumes. A large percentage of Parshall flumes with geometry inaccuracies was also found from previous data collected for this project. One reoccurring issue was that the flumes had not been well maintained and had damage to the walls or floor. Some of these Parshall flumes did not have a diverging downstream section and are referred to as Montana flumes. In these cases, a standard Parshall rating curve was used to determine flow where it did not apply. Some of the flumes that were tested operated regularly under submerged conditions, and no adjustments were made for submergence. The objective of this research is to determine if Montana flumes (Parshall flumes without a diverging section) operate similarly to fully constructed Parshall flumes under both free-flow and submerged conditions. Laboratory tests were performed in the Utah Water Research Laboratory to determine corrections for submergence. Flow 3D, a computational fluid dynamics (CFD) software program, was also used to develop corrections for a submerged Montana flume. The laboratory results were compared to the computational fluid dynamics results. By using Flow 3D, a reliable numerical process was developed to determine the flow rate in a submerged Montana flume in an effort to expand the results to other seized flumes.

title: Library Synthesis of Anticancer and Antibacterial Agents via Azide Chemistry
Creators: name: Zhang, Jianjun
Publisher: name: Utah State University

description: Various anticancer and antibacterial agents have been synthesized via azide chemistry by taking advantage of carbohydrate. Starting from the synthesis of 14 glycosyl azides, a library of carbohydrate-oxazolidinone conjugates and a library of carbohydrate-cyclopamine conjugates with biological interests were synthesized based on a highly efficient "click reaction" assisted by sonication. Some of the conjugates have improved solubility and enhanced anticancer activity. A library of neomycin B derivatives with various modifications at the 5" position has been synthesized. Two leads exhibit prominent activity against both methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Antibacterial activities were measured when combined with other clinically used antibiotics and significant synergistic activities were observed. Three different classes of aryl N-glycosides have been synthesized by employing 1,4-naphthoquinone and glycosyl azides undergoing a [2+3] cycloaddition. Alkyl azides can also undergo the same cycloaddition. After the removal of the protecting group, a library of 9,10-anthraquinone derivatives with potential anticancer activity and a library of 2-aminomethylene-1,3-indanediones with novel antibacterial activity have been developed, respectively. A one-pot three-component [2+3] cycloaddition for the synthesis of 1-alkyl 1H-naphtho[2,3-d][1,2,3]triazole-4,9-dione and 2-alkyl 2H-naphtho[2,3-d][1,2,3] triazole-4,9-dione has been developed. By taking the advantage of their difference in basicity, both products can be obtained in good purity. Using an allylic azide rearrangement, a convenient method has been developed for the synthesis of several 2',3'-dideoxyaminoglycosides. The antibacterial activity of these novel aminoglycosides also confirms the indispensable role of the 2'-NH2 group for both neomycin and kanamycin classes of aminoglycosides. A novel structural motif containing the hexylaminocarbonyl groups at O-5 and/or O-6 of 2',3'-dideoxyneamine could lead to the production of new aminoglycosides against resistant bacteria.

description: We propose a partial fraction decomposition scheme to the construction of hierarchical equations of motion theory for bosonic quantum dissipation systems. The expansion of Bose--Einstein function in this scheme shows similar properties as it applies for Fermi function. The performance of the resulting quantum dissipation theory is exemplified with spin--boson systems. In all cases we have tested the new theory performs much better, about an order of magnitude faster, than the best available conventional theory based on Matsubara spectral decomposition scheme.
