description: If quantum information processors are to fulfill their potential, the diverse errors that affect them must be understood and suppressed. But errors typically fluctuate over time, and the most widely used tools for characterizing them assume static error modes and rates. This mismatch can cause unheralded failures, misidentified error modes, and wasted experimental effort. Here, we demonstrate a spectral analysis technique for resolving time dependence in quantum processors. Our method is fast, simple, and statistically sound. It can be applied to time-series data from any quantum processor experiment. We use data from simulations and trapped-ion qubit experiments to show how our method can resolve time dependence when applied to popular characterization protocols, including randomized benchmarking, gate set tomography, and Ramsey spectroscopy. In the experiments, we detect instability and localize its source, implement drift control techniques to compensate for this instability, and then demonstrate that the instability has been suppressed.

description: Strong light-matter coupling provides a promising path for the control of quantum matter where the latter is routinely described from first-principles. However, combining the quantized nature of light with this ab initio tool set is challenging and merely developing, as the coupled light-matter Hilbert space is conceptually different and computational cost quickly becomes overwhelming. In this work, we provide a non-perturbative photon-free formulation of quantum electrodynamics (QED) in the long-wavelength limit, which is formulated solely on the matter Hilbert space and can serve as an accurate starting point for such ab initio methods. The present formulation is an extension of quantum mechanics that recovers the exact results of QED for the zero- and infinite-coupling limit, the infinite-frequency as well as the homogeneous limit and we can constructively increase its accuracy. We show how this formulation can be used to devise approximations for quantum-electrodynamical density-functional theory (QEDFT), which in turn also allows to extend the ansatz to the full minimal-coupling problem and to non-adiabatic situations. Finally, we provide a simple local-density-type functional that takes the strong coupling to the transverse photon-degrees of freedom into account and includes the correct frequency and polarization dependence. This is the first QEDFT functional that accounts for the quantized nature of light while remaining computationally simple enough to allow its application to a large range of systems. All approximations allow the seamless application to periodic systems.

description: Self-supervised visual representation learning traditionally focuses on image-level instance discrimination. Our study introduces an innovative, fine-grained dimension by integrating patch-level discrimination into these methodologies. This integration allows for the simultaneous analysis of local and global visual features, thereby enriching the quality of the learned representations. Initially, the original images undergo spatial augmentation. Subsequently, we employ a distinctive photometric patch-level augmentation, where each patch is individually augmented, independent from other patches within the same view. This approach generates a diverse training dataset with distinct color variations in each segment. The augmented images are then processed through a self-distillation learning framework, utilizing the Vision Transformer (ViT) as its backbone. The proposed method minimizes the representation distances across both image and patch levels to capture details from macro to micro perspectives. To this end, we present a simple yet effective patch-matching algorithm to find the corresponding patches across the augmented views. Thanks to the efficient structure of the patch-matching algorithm, our method reduces computational complexity compared to similar approaches. Consequently, we achieve an advanced understanding of the model without adding significant computational requirements. We have extensively pretrained our method on datasets of varied scales, such as Cifar10, ImageNet-100, and ImageNet-1K. It demonstrates superior performance over state-of-the-art self-supervised representation learning methods in image classification and downstream tasks, such as copy detection and image retrieval. The implementation of our method is accessible on GitHub.

description: Academic integrity, while important for all students, is especially so for those enrolled in nursing programs. Nurses are entrusted by the public to care for those in need from birth through death. A nursing student who graduates through dishonest means jeopardizes the safety of patients in their care. Nursing faculty need to understand the scope of academic integrity violations and develop meaningful, targeted interventions to show students the harm their actions could cause. The purpose of this dissertation is to explore undergraduate nursing students’ knowledge and perceptions of academic integrity and to specifically look at their willingness to report peer violations. This dissertation study was a collaborative effort among three doctoral students. Using a research team-modified version of McCabe’s Academic Integrity Survey as well as a research team-created Knowledge Assessment, 442 nursing students were surveyed. Results confirm a hesitation to report peers for violations of academic integrity. Students’ ability to neutralize their behaviors as harmless, their desire to remain loyal to their peers, and age act as positive predictive variables for willingness to report peer violations. Additionally, participants’ perceptions of the severity of various offenses and their perceptions of their faculty’s support for academic integrity policies are positively correlated with willingness to report peer violations. Program improvement strategies, such as implementing an honor code, were supported by participants and may help foster a culture of academic integrity that promotes peer reporting. Lastly, a targeted intervention designed for nursing students to promote academic integrity and peer reporting is explored.

description: The scaled boundary finite element method (SBFEM) is a semi-analytical computational scheme, which is based on the characteristics of the finite element method (FEM) and combines the advantages of the boundary element method (BEM). This paper integrates the scaled boundary finite element method (SBFEM) and the polygonal mesh technique into a new approach to solving the steady-state and transient seepage problems. The proposed method is implemented in Abaqus using a user-defined element (UEL). The detailed implementations of the procedure, defining the UEL element, updating the RHS and AMATRX, and solving the stiffness/mass matrix by the eigenvalue decomposition are presented. Several benchmark problems from seepage are solved to validate the proposed implementation. Results show that the polygonal element of PS-SBFEM has a higher accuracy rate than the standard FEM element in the same element size. For the transient problems, the results between PS-SBFEM and the FEM are in excellent agreement. Furthermore, the PS-SBFEM with quadtree meshes shows a good effect for solving complex geometric in the seepage problem. Hence, the proposed method is robust accurate for solving the steady-state and transient seepage problems. The developed UEL source code and the associated input files can be downloaded from https://github.com/yangyLab/PS-SBFEM.

description: The purpose of this work is to describe the (category of) Higgs bundles on a complex scheme X having a given cameral cover X~. We show that this category is a T_{X~}-gerbe, where T_{X~} is a certain sheaf of abelian groups on X, and we describe the class of this gerbe precisely. In particular, it follows that the set of isomorphism classes of Higgs bundles with a fixed cameral cover X~ is a torsor over the group H^1(X, T_{X~}), which itself parametrizes T_{X~}-torsors on X. This underlying group can be described as a generalized Prym variety, whose connected component is either an abelian variety or a degeneration thereof.

description: This study selected a total of 190 transit hubs across Shanghai, Hong Kong, and Tokyo to empirically examine whether the built environment around transit hubs shares the same attributes and how the built environment features may be related to the characteristics of transit hubs. Spatial analysis using ArcGIS was adopted to explore the distribution of built environment features around transit hubs. Linear regression models were established to evaluate the quantitative relationships between six indicators of transit hubs (intramodal connection, intermodal connection, proximity to CBD, proximity to other metro stations, cluster effect, and time effect) and five built environment metrics (population density, building density, land use mix, intersection density, and housing price). Among all the built environment features, building density is the most possible one to be shared around transit hubs. The regression results revealed that the built environment features had different degrees of correlation with the characteristics of transit hubs. Proximity to CBD and years in operation (time effect) for transit hubs were demonstrated to be the most important indicators related to the built environment. The significant relationships between transit hubs and the built environment illustrated in this study are helpful to understand station areas’ development dynamics.

description: In the field of correlated electron materials, the relation between the resonating spin singlet and antiferromagnetic states has long been an attractive topic for understanding of the interesting macroscopic quantum phenomena, such as the ones emerging from magnetic frustrated materials, antiferromagnets and high-temperature superconductors. SrCu2(BO3)2 is a well-known quantum magnet, and it is theoretically expected to be the candidate of correlated electron material for clarifying the existence of a pressure-induced deconfined quantum critical point (DQCP), featured by a continuous quantum phase transition, between the plaquette-singlet (PS) valence bond solid phase and the antiferromagnetic (AF) phase. However, the real nature of the transition is yet to be identified experimentally due to the technical challenge. Here we show the experimental results for the first time, through the state-of-the-art high-pressure heat capacity measurement, that the PS-AF phase transition of the pressurized SrCu2(BO3)2 at zero field is clearly a first-order one. Our result clarifies the more than two-decade long debates about this key issue, and resonates nicely with the recent quantum entanglement understanding that the theoretically predicted DQCPs in representative lattice models are actually a first-order transition. Intriguingly, we also find that the transition temperatures of the PS and AF phase meet at the same pressure-temperature point, which signifies a bi-critical point as those observed in Fe-based superconductor and heavy-fermion compound, and constitutes the first experimental discovery of the pressure-induced bi-critical point in frustrated magnets. Our results provide fresh information for understanding the evolution among different spin states of correlated electron materials under pressure.

description: Objective: Previous studies have explored impacts of school gardening on students and detailed broad components needed for successful gardens, but little is known about how gardens are maintained, connected academically, valued, and sustained over time. The purpose of this observational study is to explore how school gardens become institutionalized and create an implementation framework that can be used to establish gardens that are well integrated into curriculum and culture.
      Study Design, Setting, Participants, Intervention: A stratified, purposeful sample of school gardeners at 21 Manhattan, Brooklyn, and Bronx schools completed a survey, semi-structured interviews, and concept mapping exercises during the 2013-2014 school year.  Additional data collected were student observations, garden images, and related documents.
      Outcome Measures and Analysis: The survey was analyzed using descriptive statistics.  Interviews, photos, observations and documents were qualitatively analyzed through thematic coding, pattern matching, explanation building, and cross-case synthesis.  Concept mapping exercises was analyzed quantitatively by entering participants’ sorted statements into a similarity matrix to conduct multi-dimensional scaling and hierarchical cluster analysis and qualitatively by thematic coding.
      Results: Survey, interview and observation data explicated how school gardeners used implementation strategies to overcome barriers, create new learning opportunities for students, and facilitate permeation of gardening into the school culture. The quantitative concept mapping analysis resulted in four school garden domains (resources and support, physical garden, student experience, and school community) and 19 domain components.  Qualitative analysis of sorted statements and interviews elucidated relationships between each domain’s components and also the domains to each other.  An integration of all data produced a rich description, supplemented with images, of each school garden’s unique and varied characteristics, activities and operation. A synthesis of these analyses produced the School Garden Integration Framework (SGIF), which visually depicts how and when to implement each domain and all components to maximize garden integration.  Additionally, a scaled tool (Scale) was created to capture and rate varying degrees of domain and component integration.
      Conclusion and Implications: The SGIF, Scale, and implementation strategies that emerged from this study can be used by schools or policymakers to strengthen existing or establish new well-integrated school gardening programs.

description: In a recent letter [Phys.Rev.Lett. {\bf 30}, 3269 (1995), chao-dyn/9510011], we reported that a macroscopic chaotic determinism emerges in a multistable system: the unidirectional motion of a dissipative particle subject to an apparently symmetric chaotic noise occurs even if the particle is in a spatially symmetric potential. In this paper, we study the global dynamics of a dissipative particle by investigating the barrier crossing probability of the particle between two basins of the multistable potential. We derive analytically an expression of the barrier crossing probability of the particle subject to a chaotic noise generated by a general piecewise linear map. We also show that the obtained analytical barrier crossing probability is applicable to a chaotic noise generated not only by a piecewise linear map with a uniform invariant density but also by a non-piecewise linear map with non-uniform invariant density. We claim, from the viewpoint of the noise induced motion in a multistable system, that chaotic noise is a first realization of the effect of {\em dynamical asymmetry} of general noise which induces the symmetry breaking dynamics.

description: Chiral properties have seen increasing use in recent years, leading to the emerging fields of chiral quantum optics, plasmonics, and phononics. While these fields have achieved manipulation of the chirality of light and lattice vibrations, controlling the chirality of materials on demand has yet remained elusive. Here, we demonstrate that linearly polarized phonons can be used to induce geometric chirality in achiral crystals when excited with an ultrashort laser pulse. We show that nonlinear phonon coupling quasistatically displaces the crystal structure along phonon modes that reduce the symmetry of the lattice to that of a chiral point group corresponding to a chiral crystal. By reorienting the polarization of the laser pulse, the two enantiomers can be induced selectively. Therefore, geometric chiral phonons enable the light-induced creation of chiral crystal structures and offer a pathway to engineering chiral electronic states and optical properties.

description: We study the variant of Particle Swarm Optimization (PSO) that applies random velocities in a dimension instead of the regular velocity update equations as soon as the so-called potential of the swarm falls below a certain bound in this dimension, arbitrarily set by the user. In this case, the swarm performs a forced move. In this paper, we are interested in how, by counting the forced moves, the swarm can decide for itself to stop its movement because it is improbable to find better solution candidates as it already has found. We formally prove that when the swarm is close to a (local) optimum, it behaves like a blind-searching cloud, and that the frequency of forced moves exceeds a certain, objective function-independent value. Based on this observation, we define stopping criteria and evaluate them experimentally showing that good solution candidates can be found much faster than applying other criteria.

description: An operator sum representation is derived for a decoherence-free subspace (DFS) and used to (i) show that DFSs are the class of quantum error correcting codes (QECCs) with fixed, unitary recovery operators, and (ii) find explicit representations for the Kraus operators of collective decoherence. We demonstrate how this can be used to construct a concatenated DFS-QECC code which protects against collective decoherence perturbed by independent decoherence. The code yields an error threshold which depends only on the perturbing independent decoherence rate.

In fact, the "if" implication holds for all $k\geq 1$.

description: Dual-comb spectroscopy is a promising method for precise optical spectrum analysis with fast data acquisition speed. However, its implementation and applications are often hindered by the complexity of optical comb systems. Here, as a compact and robust system, femtosecond imbalanced time-stretch spectroscopy (FITSS) with simple optical layout is proposed and demonstrated. The time-stretch interferometry from one femtosecond laser builds a mapping from the optical frequency domain to the radio frequency regime. In experiment, the absorption line of a hydrogen cyanide cell is encoded in the probing arm of a Mach-Zehnder interferometer (MZI). The down-converted radio frequency comb is transformed from a periodically chirped waveform, which is the interferogram of the MZI with different dispersion values on two arms. By turning the optical filter, the spectrum over a wide range is analyzed.

description: The escalating frequencies and changing patterns of climate change effects such as precipitation rates and sea levels on existing floodplain catchments should raise a red flag regarding the un-coped design and planning criteria that designers and decision makers need to account for. In addition, the sustainability of the engineering infrastructure, which is under pressure from changing climate patterns, is vital. As a result, it is important to continuously assess and appraise the existing infrastructure—for instance, the reliability and resiliency of floodplain catchments—and therefore lessen the threatening impacts and risks. Research on flood emergency management is crucial in order to reduce the potential hazard of life and property loss. A flood impact assessment methodology is proposed and examined. The key technologies include a flood-routing simulation based on a twodimensional (2D) hydrodynamic model and a flood risk assessment based on performance assessment indicators. The 2D hydrodynamic model can quickly calculate flood-submerged areas, floodwater depth distribution and flood-routing times. The flood risk assessment has improved the efficiency of flood emergency management and could offer more help in relation to risk indications. The research results provide a developed tool to analyse flood risk rapidly and ensure that schemes are in place for flood resistance.

description: We introduce a class of one-dimensional discrete space-discrete time stochastic growth models described by a height function $h_t(x)$ with corner initialization. We prove, with one exception, that the limiting distribution function of $h_t(x)$ (suitably centered and normalized) equals a Fredholm determinant previously encountered in random matrix theory. In particular, in the universal regime of large $x$ and large $t$ the limiting distribution is the Fredholm determinant with Airy kernel. In the exceptional case, called the critical regime, the limiting distribution seems not to have previously occurred. The proofs use the dual RSK algorithm, Gessel's theorem, the Borodin-Okounkov identity and a novel, rigorous saddle point analysis. In the fixed $x$, large $t$ regime, we find a Brownian motion representation. This model is equivalent to the Seppäläinen-Johansson model. Hence some of our results are not new, but the proofs are.

(3+1)D path integral state sums on curved U(1) bundles and U(1) anomalies of (2+1)D topological phases

description: Given the algebraic data characterizing any (2+1)D bosonic or fermionic topological order with a global symmetry group $G = \mathrm{U}(1) \rtimes H$, we construct a (3+1)D topologically invariant path integral in the presence of a curved background $G$ gauge field, as an exact combinatorial state sum. Specifically, the $\mathrm{U}(1)$ component of the $G$ gauge field can have a non-trivial second Chern class, extending previous work that was restricted to flat $G$ bundles. Our construction expresses the $\mathrm{U}(1)$ gauge field in terms of a Villain formulation on the triangulation, which includes a 1-form $\mathbb{R}$ gauge field and 2-form $\mathbb{Z}$ gauge field. We develop a new graphical calculus for anyons interacting with "Villain symmetry defects", associated with the 1-form and 2-form background gauge fields. This graphical calculus is used to define the (3+1)D path integral, which can describe either a bosonic or fermionic symmetry-protected topological (SPT) phase. For example, we can construct the topological path integral on curved $\mathrm{U}(1)$ bundles for the (3+1)D fermionic topological insulator in class AII and topological superconductor in class AIII given appropriate (2+1)D fermionic symmetry fractionalization data; these then give invariants of 4-manifolds with Spin$^c$ or Pin$^c$ structures and their generalizations. The (3+1)D path integrals define anomaly indicators for the (2+1)D topological orders; in the case of Abelian (2+1)D topological orders, we derive by explicit computation all of the mixed $\mathrm{U}(1)$ anomaly indicator formulas proposed by Lapa and Levin. We also propose a Spin$^c$ generalization of the Gauss-Milgram sum, valid for super-modular categories.

description: We study the practical performance of quantum-inspired algorithms for recommendation systems and linear systems of equations. These algorithms were shown to have an exponential asymptotic speedup compared to previously known classical methods for problems involving low-rank matrices, but with complexity bounds that exhibit a hefty polynomial overhead compared to quantum algorithms. This raised the question of whether these methods were actually useful in practice. We conduct a theoretical analysis aimed at identifying their computational bottlenecks, then implement and benchmark the algorithms on a variety of problems, including applications to portfolio optimization and movie recommendations. On the one hand, our analysis reveals that the performance of these algorithms is better than the theoretical complexity bounds would suggest. On the other hand, their performance as seen in our implementation degrades noticeably as the rank and condition number of the input matrix are increased. Overall, our results indicate that quantum-inspired algorithms can perform well in practice provided that stringent conditions are met: low rank, low condition number, and very large dimension of the input matrix. By contrast, practical datasets are often sparse and high-rank, precisely the type that can be handled by quantum algorithms.

description: In a recent paper, Kolountzakis and Papageorgiou ask if for every $ε\in (0,1]$, there exists a set $S \subseteq \mathbb{R}$ such that $\vert S \cap I\vert \geq 1 - ε$ for every interval $I \subset \mathbb{R}$ with unit length, but that does not contain any affine copy of a given increasing sequence of exponential growth or faster. This question is an analogue of the well-known Erdős similarity problem. In this paper, we show that for each sequence of real numbers whose integer parts form a set of positive upper Banach density, one can explicitly construct such a set $S$ that contains no affine copy of that sequence. Since there exist sequences of arbitrarily rapid growth that satisfy this condition, our result answers Kolountzakis and Papageorgiou's question in the affirmative. A key ingredient of our proof is a generalization of results by Amice, Kahane, and Haight from metric number theory. In addition, we construct a set $S$ with the required property -- but with $ε\in (1/2, 1]$ -- that contains no affine copy of $\{2^n\}$.

description: Social recommendation leverages social information to solve data sparsity and cold-start problems in traditional collaborative filtering methods. However, most existing models assume that social effects from friend users are static and under the forms of constant weights or fixed constraints. To relax this strong assumption, in this paper, we propose dual graph attention networks to collaboratively learn representations for two-fold social effects, where one is modeled by a user-specific attention weight and the other is modeled by a dynamic and context-aware attention weight. We also extend the social effects in user domain to item domain, so that information from related items can be leveraged to further alleviate the data sparsity problem. Furthermore, considering that different social effects in two domains could interact with each other and jointly influence user preferences for items, we propose a new policy-based fusion strategy based on contextual multi-armed bandit to weigh interactions of various social effects. Experiments on one benchmark dataset and a commercial dataset verify the efficacy of the key components in our model. The results show that our model achieves great improvement for recommendation accuracy compared with other state-of-the-art social recommendation methods.

Exploring Nursing Students’ Knowledge and Attitudes Regarding Academic Integrity: Perceptions of Severity

description: Academic integrity is an important part of higher education. This is especially true in nursing education programs. Nurses must be able to think critically, have sound clinical judgement, and make autonomous decisions. If there are concerns of academic integrity violations during nursing programs, these skills become questionable when the student enters the nursing profession. Nursing students believe that the severity of academic integrity violations occur along a continuum, which impacts their acceptance of these violations. Severity may also impact a student’s willingness to report a peer for a violation of academic integrity. This cross-sectional, correlational study assessed baccalaureate nursing students’ perceptions on various aspects of academic integrity violations using McCabe’s Academic Integrity Survey-Modified for Nursing Students (MAIS-MNS) and a knowledge assessment. Correlations, t tests, and regression analysis were used to identify relationships among variables and potential predictive factors between classroom and clinical violations, willingness to report peers, and perceived program supports. This study also considered the theory of neutralization as a factor in student acceptance of academic integrity violations. Results suggest that the perceived severity of cheating in the classroom can predict the perceived perception of severity in the clinical setting. Results also showed that students who neutralize their actions, do not perceive those actions as severe. Finally, the perception of severity does predict a student’s willingness to report peer violations of academic integrity. Creating a culture of academic integrity has the potential to reduce academic integrity violations. Creating this culture, partially through education on academic integrity and violations of academic integrity, is needed to enhance nursing education programs and ensure the continued excellence expected of nurses.
