description: Recently, one critical issue looms large in the field of recommender systems -- there are no effective benchmarks for rigorous evaluation -- which consequently leads to unreproducible evaluation and unfair comparison. We, therefore, conduct studies from the perspectives of practical theory and experiments, aiming at benchmarking recommendation for rigorous evaluation. Regarding the theoretical study, a series of hyper-factors affecting recommendation performance throughout the whole evaluation chain are systematically summarized and analyzed via an exhaustive review on 141 papers published at eight top-tier conferences within 2017-2020. We then classify them into model-independent and model-dependent hyper-factors, and different modes of rigorous evaluation are defined and discussed in-depth accordingly. For the experimental study, we release DaisyRec 2.0 library by integrating these hyper-factors to perform rigorous evaluation, whereby a holistic empirical study is conducted to unveil the impacts of different hyper-factors on recommendation performance. Supported by the theoretical and experimental studies, we finally create benchmarks for rigorous evaluation by proposing standardized procedures and providing performance of ten state-of-the-arts across six evaluation metrics on six datasets as a reference for later study. Overall, our work sheds light on the issues in recommendation evaluation, provides potential solutions for rigorous evaluation, and lays foundation for further investigation.

description: We examine in detail 15 Babylonian observations of lunar appulses and occultations made between 80 and 419 BC for the purpose of setting useful limits on Earth's clock error, as quantified by $Δ$T, the difference between Terrestrial Time and Universal time. Our results are generally in agreement with reconstructions of $Δ$T using untimed solar eclipse observations from the same period. We suggest a revised version of the simple quadratic fit to $Δ$T in light of the new results.

Subjects: subject: Optimization and Control (math.OC)
subject: Dynamical Systems (math.DS)

description: Output reference tracking of unknown nonlinear systems is considered. The control objective is exact tracking in predefined finite time, while in the transient phase the tracking error evolves within a prescribed boundary. To achieve this, a novel high-gain feedback controller is developed that is similar to, but extends, existing high-gain feedback controllers. Feasibility and functioning of the proposed controller is proven rigorously. Examples for the particular control objective under consideration are, for instance, linking up two train sections, or docking of spaceships.

description: In this paper, we report on the $τ$-tilting finiteness of some classes of finite-dimensional algebras over an algebraically closed field, including symmetric algebras of polynomial growth, $0$-Hecke algebras and $0$-Schur algebras. Consequently, we find that derived equivalence preserves the $τ$-tilting finiteness over symmetric algebras of polynomial growth, and self-injective cellular algebras of polynomial growth are $τ$-tilting finite. Furthermore, the representation-finiteness and $τ$-tilting finiteness over $0$-Hecke algebras and $0$-Schur algebras (with few exceptions) coincide.

description: The present research employed a dynamic approach to language learning and traced the co- development of English language learners’ private and social foreign language enjoyment (FLE). To this aim, a factor of curves model (FCM) was used, as an innovative statistical procedure, to trace the covariance of the subdomains of FLE longitudinally on four measurement occasions and to explore the covariance of the initial state and slope of the sub- domains of FLE and how variation in private and social FLE can be explained by the underlying global factor of FLE. For data collection, the FLE scale developed by Dewaele and MacIntyre (2014) was distributed to 437 adult EFL learners in four phases. The data were analyzed in Mplus in three steps suggested by Wickrama et al (2016). The results indicated that all growth parameters across the two primary growth curves (intercepts and slopes of private FLE and social FLE) were statistically significant. This confirmed the existence of sufficient inter-individual variation and intra-individual trend within each subdomain of FLE and a significant increase over time in these subdomains. Also, the primary growth factors of private FLE and social FLE differentially contributed to second-order growth factors of FLE. Finally, the variances of the intercept and slope of each second subdomain were revealed to be largely explained by the global factor of FLE. These findings were discussed in the light of the potential variables associated with FLE.

description: In this paper, we introduce Quantum Geometric Entanglement Theory (QGET), an novel theoretical framework that rigorously probes the intricate relationship between quantum entanglement and the emergence of space time geometry. QGET not only serves to significantly enrich our grasp of quantum gravity but also illuminates hitherto uncharted dimensions within this profound phenomenon. We present a suite of empirically testable predictions and meticulously dissect their conceivable implications. Furthermore, we conduct a comprehensive study of the requisite experimental prerequisites for the unequivocal detection of space-time entanglement. QGET emerges as an exceptionally promising and pivotal instrument poised to propel our foundational comprehension of quantum gravity and the inherent fabric of space-time.

description: The aurorae of Uranus were recently detected in the far ultraviolet with the Hubble Space Telescope (HST) providing a new, so far unique, means to remotely study the asymmetric Uranian magnetosphere from Earth. We analyze here two new HST Uranus campaigns executed in Sept. 2012 and Nov. 2014 with different temporal coverage and under variable solar wind conditions numerically predicted by three different MHD codes. Overall, HST images taken with the Space Telescope Imaging Spectrograph reveal auroral emissions in three pairs of successive images (one pair acquired in 2012 and two in 2014), hence six additional auroral detections in total, including the most intense Uranian aurorae ever seen with HST. The detected emissions occur close the expected arrival of interplanetary shocks. They appear as extended spots at southern latitudes, rotating with the planet. They radiate 5-24 kR and 1.3-8.8 GW of ultraviolet emission from H$_2$, last for tens of minutes and vary on timescales down to a few seconds. Fitting the 2014 observations with model auroral ovals constrains the longitude of the southern (northern) magnetic pole to 104+\-26° (284-\-26°) in the Uranian Longitude System. We suggest that the Uranian near-equinoctial aurorae are pulsed cusp emissions possibly triggered by large-scale magnetospheric compressions.

description: The well-known theorem of Shalom--Vaserstein and Ershov--Jaikin-Zapirain states that the group $\mathrm{EL}_n(\mathcal{R})$, generated by elementary matrices over a finitely generated commutative ring $\mathcal{R}$, has Kazhdan's property (T) as soon as $n\geq3$. This is no longer true if the ring $\mathcal{R}$ is replaced by a commutative rng (a ring but without the identity) due to nilpotent quotients $\mathrm{EL}_n(\mathcal{R}/\mathcal{R}^k)$. In this paper, we prove that even in such a case the group $\mathrm{EL}_n(\mathcal{R})$ satisfies a certain property that can substitute property (T), provided that $n$ is large enough.

description: Replacing fish meal and oil in trout diets with plant-derived ingredients is a contemporary challenge to move towards more sustainable aquaculture practices. However, such dietary replacement causes hepatic metabolic changes that have not yet been elucidated. Here, we aimed to decipher the effect of a 100% plant-based diet on the hepatic global DNA methylation landscape in trout and assess whether changes depend on fish genetic background. We analysed the global methylome and the expression of DNA (de)methylation-related genes of three isogenic lines that exhibit similar growth when fed a marine resource-based diet (M diet), but differ in their responses to a plant-based diet (V diet). Our results revealed that the V diet induced a decrease in 5-cytosine combined with an increase in 5-hydroxymethylcytosine in two of the three analysed lines. For one of these 2 affected lines, when fed the M diet but at the same feed intake of the V diet (MR), no methylome differences were highlighted between M and MR or between MR and V-fed trout whereas for the other affected line, M fed trout displayed a divergent methylome profile from MR and V fed fish. DNA (de)methylation-related genes were also affected by the V or MR diets. Our findings showed that the global hepatic methylome of trout is affected by a V diet, depending on genetic background. This latter effect seems to be due to either a decreased feed intake alone or combined with the effect of the dietary composition per se.

description: Extracting biochemical information from cell and tissue autofluorescence without using any external biomarkers is a promising approach for disease diagnosis and treatment. This thesis reports the advancement of fluorescence microscopy and image acquisition tools to observe autofluorescence signals, and I intended to use these signals as a biomarker for disease diagnosis and classification. In this research, I applied the hyperspectral imaging technique in observing the autofluorescence signals in peripheral blood monocytes from both healthy control and motor neuron disease patients. Current motor neuron disease diagnosis and classification methods are mainly based on clinical observations, which depends upon an experienced neurologist to make an informed clinical judgment. The development of an early-stage biomarker would be beneficial for the diagnosis of this disease. Research presented in this thesis centers around the identification of distinct autofluorescence features from the peripheral blood monocytes, which can help reveal the difference between a healthy person and a motor neuron disease patient. From my result, a novel biomarker is discovered by applying the hyperspectral image technique. It is based on the mean cell intensity per unit area on a selection of channels. According to 15 samples, the classification methods showed promising results. With further validation, it may be applied in motor neuron disease classification.

A probabilistic version of this decoder can be implemented in O(N^1.5) bit operations.

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: The shape of a rotating electric solar wind sail under the centrifugal force and solar wind dynamic pressure is modeled to address the sail attitude maintenance and thrust vectoring. The sail rig assumes centrifugally stretched main tethers that extend radially outward from the spacecraft in the sail spin plane. Furthermore, the tips of the main tethers host remote units that are connected by auxiliary tethers at the sail rim. Here, we derive the equation of main tether shape and present both a numerical solution and an analytical approximation for the shape as parametrized both by the ratio of the electric sail force to the centrifugal force and the sail orientation with respect to the solar wind direction. The resulting shape is such that near the spacecraft, the roots of the main tethers form a cone, whereas towards the rim, this coning is flattened by the centrifugal force, and the sail is coplanar with the sail spin plane. Our approximation for the sail shape is parametrized only by the tether root coning angle and the main tether length. Using the approximate shape, we obtain the torque and thrust of the electric sail force applied to the sail. As a result, the amplitude of the tether voltage modulation required for the maintenance of the sail attitude is given as a torque-free solution. The amplitude is smaller than that previously obtained for a rigid single tether resembling a spherical pendulum. This implies that less thrusting margin is required for the maintenance of the sail attitude. For a given voltage modulation, the thrust vectoring is then considered in terms of the radial and transverse thrust components.

description: Modelling complex real-world situations such as infectious diseases, geological phenomena, and biological processes can present a dilemma: the computer model (referred to as a simulator) needs to be complex enough to capture the dynamics of the system, but each increase in complexity increases the evaluation time of such a simulation, making it difficult to obtain an informative description of parameter choices that would be consistent with observed reality. While methods for identifying acceptable matches to real-world observations exist, for example optimisation or Markov chain Monte Carlo methods, they may result in non-robust inferences or may be infeasible for computationally intensive simulators. The techniques of emulation and history matching can make such determinations feasible, efficiently identifying regions of parameter space that produce acceptable matches to data while also providing valuable information about the simulator's structure, but the mathematical considerations required to perform emulation can present a barrier for makers and users of such simulators compared to other methods. The hmer package provides an accessible framework for using history matching and emulation on simulator data, leveraging the computational efficiency of the approach while enabling users to easily match to, visualise, and robustly predict from their complex simulators.

Understanding Teacher Leadership in New York City Through Complexity Theory

Year: 2023

description: Since the early 2000s, parallel to the growing prominence of school accountability mechanisms, teacher leadership programs have increasingly focused on leveraging teacher leaders (TLs) to provide vital expertise and human resources to expand instructional capacity in schools. However, in the United States, school districts, which continue to prefer evaluative models that focus on student achievement outcomes, have struggled to evaluate the success of such teacher leadership programs, which primarily aim to improve harder-to-measure outcomes, such as collaboration, teacher instructional practice, and the distribution of leadership at the school site. In this study, researchers partnered with practitioners at the New York City Department of Education to analyze Teacher Career Pathways, a teacher leadership program in the United States’ largest school system. We apply for the first time Margolis’ (2020) complexity theory for teacher leadership to examine how teacher leaders (TLs) enable whole school change. Using the framework to analyze the work of TLs, we can better understand 1) how TLs function within their school to help school leaders and teachers obtain more accurate information to improve teaching and learning, 2) process this information, and 3) feed that information back into the communication network to influence decisions across the system. This study also contributes to early work on using complexity theory to analyze and evaluate teacher leadership programs, offering a new model that emphasizes examining how teacher leadership works in practice over student achievement outcomes.

Our results extend a fundamental inequality of Naor for the hypercube (with profound consequences in metric geometry) to discrete groups. Different inequalities are established in terms of directional derivatives which are constructed via affine representations determined by the Fourier truncations. Our proofs rely on the Banach $\mathrm{X}_p$ nature of noncommutative $L_p$-spaces and dimension-free estimates for noncommutative Riesz transforms. In the particular case of free groups we use an alternative approach based on free Hilbert transforms.

description: The nature of the magnetic structure arising from ion specular reflection in shock compression studies is examined by means of 1d particle in cell simulations. Propagation speed, field profiles and supporting currents for this magnetic structure are shown to be consistent with a magnetosonic soliton. Coincidentally, this structure and its evolution are typical of foot structures observed in perpendicular shock reformation. To reconcile these two observations, we propose, for the first time, that shock reformation can be explained as the result of the formation, growth and subsequent transition to a super-critical shock of a magnetosonic soliton. This argument is further supported by the remarkable agreement found between the period of the soliton evolution cycle and classical reformation results. This new result suggests that the unique properties of solitons can be used to shed new light on the long-standing issue of shock non-stationarity and its role on particle acceleration.

The Classroom as a Complex Adaptive System (CAS): Credible Framing, Useful Metaphor or Mis-Designation?
Creators: name: Knight, Benjamin
Publisher: name: International Journal of Complexity in Education
Year: 2023

description: This paper discusses the legitimacy of framing school classrooms as complex adaptive systems (CASs) with the aim of advancing discourse about the extent to which systems within education can be usefully designated as complex. Perspectives differ on criteria for applying a complexity framing to human systems, a consequence of the lack of any single definition of complexity theory, or agreement on the framing of CAS in human networks. However, the literature on complexity and education appears to both open (ajar) and close the door on descriptions and theoretical treatment of classrooms as CASs, and as a site for complexity- sensitive empirical research. The paper begins by presenting an overview of complexity discourse with respect to education, articulates conceptual framings for CAS and classrooms then moves on to advance the principal arguments in opposition to a conception of classrooms as CASs. Arguments from those in the field who are receptive, albeit tentatively, to applying a CAS lens to classroom systems are then explained. The paper concludes that whilst these arguments have merit, the legitimacy or otherwise of framing classrooms as CASs hinges to some extent on how classrooms and CASs themselves are framed. Finally, a primer is presented for an empirical complexity-sensitive classroom study undertaken in July 2020, findings from which will be published later this year.

description: Recently two of the authors proposed a mechanism of vacuum energy sequester as a means of protecting the observable cosmological constant from quantum radiative corrections. The original proposal was based on using global Lagrange multipliers, but later a local formulation was provided. Subsequently other interesting claims of a different non-local approach to the cosmological constant problem were made, based again on global Lagrange multipliers. We examine some of these proposals and find their mutual relationship. We explain that the proposals which do not treat the cosmological constant counterterm as a dynamical variable require fine tunings to have acceptable solutions. Furthermore, the counterterm often needs to be retuned at every order in the loop expansion to cancel the radiative corrections to the cosmological constant, just like in standard GR. These observations are an important reminder of just how the proposal of vacuum energy sequester avoids such problems.

description: In the 21st century, emotional intelligence is considered an important aspect. Making the workplace run more creatively, as a result, many organizations nowadays give importance to this. In short emotional intelligence, means identifying a person’s own emotions and others. In addition, emotional intelligence is a part of critical thinking and problem-solving. As EI is related to the employee's mental situation, however, using EI management acted on how to solve the informal situation when an organization going to face it. Due to solving many informal situations and having a way to focus critical thinking emotional intelligence has been arising a number of attention from researchers and scholars. This is because using the proper use of this can lead an organization to the path of success. Furthermore, all employees are assets, and management needs to properly use employees’ abilities. Hence, emotional intelligence can help the manager to use the best of an employee’s abilities. On the other hand, the field of EI is new to the corporate world. Above all, the EI is not focused much on third-world countries. As a result, it has been observed that there is not much research has been taking place on emotional intelligence. Another reason for the lack of research in this field is that emotional intelligence is a physiological concept, and most business organizations only focus on the profitability concept. However, in the end, many big companies understand the true power of EI. Based on this fact organizations are now planning to redesign the human resource department and prefer several emotional bits of intelligence to raise company creativity.
The Spacing System and Probability Attractors: A Visual Analysis Methodology for Qualitative Systems Research
Creators: name: Greeley, Lillian
Publisher: name: International Journal of Complexity in Education
Year: 2023

description: Analysis of qualitative systems with scientific methodologies is limited because of the inherent difficulties of transforming qualitative data into measurable real number quantitative data. An adaptation of a nonlinear complex chaos system methodological tool, Ruelle and Taken’s Theorem Protocol (RTTP), substitute’s probabilities of occurrence for real numbers, allowing research into whole qualitative systems instead of analyses of parts of a system, which is how qualitative analysis has been done. It allows the function of a qualitative system, the way the parts of the system work together as an integral whole, to be probed, defined, visualized and manipulated in visual 3- and 4-dimensional space, as nonlinear complex systems are probed. This methodological tool is called a probability attractor and it transforms qualitative description into quantitative description, by one derivative, which study hadn’t been possible. Relationships between and among operations within a system can be studied with this methodology because it allows them to be visually tracked in space and time. It also allows heuristic developmental and comparative studies in the areas of teaching, learning, diagnostic and remedial tracking of systems, and their pathologies, as well as evolutionary development of social science systems such as psychology, political science, economics, linguistics, and sociology development. Studies of the component of Spacing, physical breaks from the formal work of learning, in the dialectical method of learning used in the Early Socratic Dialogues and in Matthew Lipman’s contemporary philosophical novels for children, have provided a way to focus on learning processes that partial texts alone may obscure. This article demonstrates how the component of Spacing is integral to learning and how an adaption of chaos theory methodology may become a useful research tool to study learning and other social science systems.

description: Spectroscopic studies have demonstrated that nearly all Galactic globular clusters (GCs) harbour multiple stellar populations with different chemical compositions. Moreover, colour-magnitude diagrams based exclusively on Strömgrem photometry have allowed us to identify and characterise multiple populations along the RGB of a large number of clusters. In this paper we show for the first time that Strömgren photometry is also very effcient at identifying multiple populations along the AGB, and demonstrate that the AGB of M3, M92, NGC362, NGC1851, and NGC6752 are not consistent with a single stellar population. We also provide a catalogue of RGB and AGB stars photometrically identified in these clusters for further spectroscopic follow-up studies.We combined photometry and elemental abundances from the literature for RGB and AGB stars in NGC6752 where the presence of multiple populations along the AGB has been widely debated. We find that, while the MS, SGB, and RGB host three stellar populations with different helium and light element abundances, only two populations of AGB stars are present in the cluster. These results are consistent with standard evolutionary theory.

description: The war diaries are official records kept by the Battalions during a one month period. They contain the daily orders, correspondence, newsletters, and an intelligence log detailing troop activities, locations, and weather conditions. The war diaries detail the activities and movement of the 1st Battalion from training in Canada and England to active duty on the Western Front and their return to Victoria in January 1946. This diary was kept while at Paxhill Park and Denne Park, England. It has entries about setting up camp at Paxhill in less than ideal conditions, getting the movement order to Denne Park, setting up camp in difficult conditions again, finding that the troops are welcomed by civilians in Horsham and that they are spending a good deal of their off-duty time there, making up an assault course, a grenade throwing demonstration, a private being killed by a hit and run driver, fog preventing training on a gun range, attending an Xmas party at the local Y.M.C.A, having their Christmas dinner, and planning a New Years dinner, among other activities and information.

description: The noncentrosymmetric superconductor Ru$_7$B$_3$ has in previous studies demonstrated remarkably unusual behaviour in its vortex lattice, where the nearest neighbour directions of the vortices dissociate from the crystal lattice and instead show a complex field-history dependence, and the vortex lattice rotates as the field is changed. In this study, we look at the vortex lattice form factor of Ru$_7$B$_3$ during this field-history dependence, to check for deviations from established models, such as the London model. We find that the data is well described by the anisotropic London model, which is in accordance with theoretical predictions that the alterations to the structure of the vortices due to broken inversion symmetry should be small. From this, we also extract values for the penetration depth and coherence length.

description: The expansion of HII regions can trigger the formation of stars. An overdensity of young stellar objects (YSOs) is observed at the edges of HII regions but the mechanisms that give rise to this phenomenon are not clearly identified. Moreover, it is difficult to establish a causal link between HII-region expansion and the star formation observed at the edges of these regions. A clear age gradient observed in the spatial distribution of young sources in the surrounding might be a strong argument in favor of triggering. We have observed the Galactic HII region RCW120 with herschel PACS and SPIRE photometers at 70, 100, 160, 250, 350 and 500$μ$m. We produced temperature and H$_2$ column density maps and use the getsources algorithm to detect compact sources and measure their fluxes at herschel wavelengths. We have complemented these fluxes with existing infrared data. Fitting their spectral energy distributions (SEDs) with a modified blackbody model, we derived their envelope dust temperature and envelope mass. We computed their bolometric luminosities and discuss their evolutionary stages. The herschel data, with their unique sampling of the far infrared domain, have allowed us to characterize the properties of compact sources observed towards RCW120 for the first time. We have also been able to determine the envelope temperature, envelope mass and evolutionary stage of these sources. Using these properties we have shown that the density of the condensations that host star formation is a key parameter of the star-formation history, irrespective of their projected distance to the ionizing stars.

description: Beurling-Carleson sets have appeared in a number of areas of complex analysis such as boundary zero sets of analytic functions, inner functions with derivative in the Nevanlinna class, cyclicity in weighted Bergman spaces, Fuchsian groups of Widom-type and the corona problem in quotient Banach algebras. After surveying these developments, we give a general definition of Beurling-Carleson sets and discuss some of their basic properties. We show that the Roberts decomposition characterizes measures that do not charge Beurling-Carleson sets.
 For a positive singular measure $μ$ on the unit circle, let $S_μ$ denote the singular inner function with singular measure $μ$. In the second part of the paper, we use a corona-type decomposition to relate a number of properties of singular measures on the unit circle such as membership of $S'_μ$ in the Nevanlinna class $\mathcal N$, area conditions on level sets of $S_μ$ and wepability. It was known that each of these properties holds for measures concentrated on Beurling-Carleson sets. We show that each of these properties implies that $μ$ lives on a countable union of Beurling-Carleson sets. We also describe partial relations involving the membership of $S'_μ$ in the Hardy space $H^p$, membership of $S_μ$ in the Besov space $B^p$ and $(1-p)$-Beurling-Carleson sets and give a number of examples which show that our results are optimal.
 Finally, we show that measures that live on countable unions of $α$-Beurling-Carleson sets are almost in bijection with nearly-maximal solutions of $Δu = u^p \cdot χ_{u > 0}$ when $p > 3$ and $α= \frac{p-3}{p-1}$.

description: 80% of all Renewable Energy Power in Germany is installed in tree-like distribution grids. Intermittent power fluctuations from such sources introduce new dynamics into the lower grid layers. At the same time, distributed resources will have to contribute to stabilize the grid against these fluctuations in the future. In this paper, we model a system of distributed resources as oscillators on a tree-like, lossy power grid and its ability to withstand desynchronization from localized intermittent renewable infeed. We find a remarkable interplay of network structure and the position of the node at which the fluctuations are fed in. An important precondition for our findings is the presence of losses in distribution grids. Then, the most network central node splits the network into branches with different influence on network stability. Troublemakers, i.e. nodes at which fluctuations are especially exciting the grid, tend to be downstream branches with high net power outflow. For low coupling strength, we also find branches of nodes vulnerable to fluctuations anywhere in the network. These network regions can be predicted at high confidence using an eigenvector based network measure taking the turbulent nature of perturbations into account. While we focus here on tree-like networks, the observed effects also appear, albeit less pronounced, for weakly meshed grids. On the other hand the observed effects disappear for lossless power grids often studied in the complex systems literature.
