description: Today, the Ising model is an archetype describing collective ordering processes. And, as such, it is widely known in physics and far beyond. Less known is the fact that the thesis defended by Ernst Ising 100 years ago (in 1924) contained not only the solution of what we call now the `classical 1D Ising model' but also other problems. Some of these problems, as well as the method of their solution, are the subject of this note. In particular, we discuss the combinatorial method Ernst Ising used to calculate the partition function for a chain of elementary magnets. In the thermodynamic limit, this method leads to the result that the partition function is given by the roots of a certain polynomial. We explicitly show that `Ising's roots' that arise within the combinatorial treatment are also recovered by the eigenvalues of the transfer matrix, a concept that was introduced much later. Moreover, we discuss the generalization of the two-state model to a three-state one presented in Ising's thesis, but not included in his famous paper of 1925 (E. Ising, Z.Physik 31 (1925) 253). The latter model can be considered as a forerunner of the now abundant models with many-component order parameters.

description: Critical phenomena in phase transitions of strongly interacting matter, governed by quantum chromodynamics, are inherently encoded in the fluctuations of conserved charges. In this work, we study the net-baryon number density fluctuations, including the lowest-lying nucleon and the baryonic resonance $Δ(1232)$, based on the parity doublet model in the mean-field approximation. We focus on the qualitative features of the second-order susceptibility of the net-baryon number density in dense hadronic matter and how the inclusion of $Δ(1232)$ affects it. We demonstrate that the fluctuations of the individual baryons do not necessarily reflect the total net-baryon number fluctuations at finite density, due to the non-trivial correlations between different particle species. Our results highlight the role of baryonic correlations in the interpretation of data from heavy ion collision experiments.

description: In this article we consider the influence of a periodic sequence of Gaussian pulses on a chimera state in a ring of coupled FitzHugh-Nagumo systems. We found that on the way to complete spatial synchronization one can observe a number of variations of chimera states that are not typical for the parameter range under consideration. For example, the following modes were found: breathing chimera, chimera with intermittency in the incoherent part, traveling chimera with strong intermittency, and others. For comparison, here we also consider the impact of a harmonic influence on the same chimera, and to preserve the generality of the conclusions, we compare the regimes caused by both a purely positive harmonic influence and a positive-negative one.

Accelerating QM/MM simulations of electrochemical interfaces through machine learning of electronic charge densities

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: A crucial aspect in the simulation of electrochemical interfaces consists in treating the distribution of electronic charge of electrode materials that are put in contact with an electrolyte solution. Recently, it has been shown how a machine-learning method that specifically targets the electronic charge density, also known as SALTED, can be used to predict the long-range response of metal electrodes in model electrochemical cells. In this work, we provide a full integration of SALTED with MetalWalls, a program for performing classical simulations of electrochemical systems. We do so by deriving a spherical harmonics extension of the Ewald summation method, which allows us to efficiently compute the electric field originated by the predicted electrode charge distribution. We show how to use this method to drive the molecular dynamics of an aqueous electrolyte solution under the quantum electric field of a gold electrode, which is matched to the accuracy of density-functional theory. Notably, we find that the resulting atomic forces present a small error of the order of 1 meV/Å, demonstrating the great effectiveness of adopting an electron-density path in predicting the electrostatics of the system. Upon running the data-driven dynamics over about 3 ns, we observe qualitative differences in the interfacial distribution of the electrolyte with respect to the results of a classical simulation. By greatly accelerating quantum-mechanics/molecular-mechanics approaches applied to electrochemical systems, our method opens the door to nanoseconds timescales in the accurate atomistic description of the electrical double layer.

description: Fairness and bias are crucial concepts in artificial intelligence, yet they are relatively ignored in machine learning applications in clinical psychiatry. We computed fairness metrics and present bias mitigation strategies using a model trained on clinical mental health data. We collected structured data related to the admission, diagnosis, and treatment of patients in the psychiatry department of the University Medical Center Utrecht. We trained a machine learning model to predict future administrations of benzodiazepines on the basis of past data. We found that gender plays an unexpected role in the predictions-this constitutes bias. Using the AI Fairness 360 package, we implemented reweighing and discrimination-aware regularization as bias mitigation strategies, and we explored their implications for model performance. This is the first application of bias exploration and mitigation in a machine learning model trained on real clinical psychiatry data.

description: The scientific, societal, economic, and environmental challenges associated with the changing Arctic are immense and require a coordinated approach towards observing and data collection. The EU funded project Arctic PASSION (“Pan-Arctic observing system of systems: Implementing observations for societal needs) aims to overcome the still existing challenges, such as fragmentation and lack of tailoring of observations to user needs, by co-creating a more integrated pan-Arctic observing system in international collaboration, including Indigenous Peoples and local communities. It shall allow access to unrestricted, high quality, science-based Earth observation information as well as consented Indigenous Knowledge and Local Knowledge. It shall be better tuned to the needs of society, allow monitoring environmental changes, reduce uncertainly in predictions, and support decision-making.

With a consortium consisting of 43 partners, the Arctic PASSION project put together the diverse expertise and formulated 10 recommendations on what is needed for a better coordinated and integrated, more useful and more equitable Arctic Observing System and seeking ways to sustain it.

description: Mauritia flexuosa is a key ecological and economic palm found throughout tropical South America. To inform improved management of M. flexuosa, we conducted a systematic review of published information about the ecology, livelihoods, and management of M. flexuosa, synthesized the information and identified knowledge gaps, and analyzed the spatial distribution of publications. A total of 143 documents (primary research, literature reviews, and grey literature) were reviewed. Most published information originates from Peru and Brazil, with a disproportionate number of documents based in the Loreto Department of Peru. Significant geographical gaps in published information exist, especially in the northern portion of the species range. Existing literature emphasizes M. flexuosa fruit, although leaves, oil, and other products play important roles economically. To improve M. flexuosa management, we recommend that future research focuses on: (1) M. flexuosa availability; (2) harvest and cultivation; (3) development of consistent methods and standards; (4) landscape-level issues like land use change; (5) M. flexuosa within broader systems; (6) spatial gaps in research; (7) long-term research; and (8) multi- and interdisciplinary approaches.

description: This thesis is a collection of linked short stories centered around the loss and guilt of one family. Marie is the mother of Lila and the grandmother of Nicole. Marie’s mother dies when she is young, causing her to grow up fast to take care of her father. This provides Marie with the strength to take care of the rest of the family when Lila’s daughter, Melody, disappears. Lila takes her children, Melody and Justin, camping with their cousins, Nicole and Mitch. Lila shares a ghost story that Marie had told her when she was young about the “laughing spirit” in the nearby spring that takes people. Melody becomes entranced by the story and a few nights later disappears. Lila becomes depressed. She feels guilty, believing that the story she told Melody led to her death. After visiting the site of Melody’s disappearance, she starts to believe that “laughing spirit” took her daughter. This belief causes Lila to drown herself to be closer to her daughter. Marie feels responsible for her family’s pain. She made up the story that led to both her granddaughter and daughter’s death. She must figure out how to move past this to help her grandson, Justin, who turns to drugs after Lila’s suicide. Nicole, Marie’s granddaughter and Lila’s niece, struggles with her aunt’s suicide. She has always been compared to her aunt. When her husband brings up having children, Nicole is afraid of history repeating. She struggles to move past her fear and communicate with her husband.

description: The speed and quality of single-pixel imaging (SPI) are fundamentally limited by image modulation frequency and by the levels of optical noise and compression noise. In an approach to come close to these limits, we introduce a SPI technique, which is inherently differential, and comprises a novel way of measuring the zeroth spatial frequency of images and makes use of varied thresholding of sampling patterns. With the proposed sampling, the entropy of the detection signal is increased in comparison to standard SPI protocols. Image reconstruction is obtained with a single matrix-vector product so the cost of the reconstruction method scales proportionally with the number of measured samples. A differential operator is included in the reconstruction and following the method is based on finding the generalized inversion of the modified measurement matrix with regularization in the Fourier domain. We demonstrate $256 \times 256$ SPI at up to $17~$Hz at visible and near-infrared wavelength ranges using two polarization or spectral channels. A low bit-resolution data acquisition device with alternating-current-coupling can be used in the measurement indicating that the proposed method combines improved noise robustness with a differential removal of the direct current component of the signal.

title: Detection Models for the Early Diagnosis of Type 1 Hereditary Hemochromatosis
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2020

description: Hereditary hemochromatosis (HH) is not only the most common genetic condition in persons of northern European descent (de Graaff et al., 2015), it also remains significantly misdiagnosed. The primary reason for this failure to diagnose the disease is that it lacks significant clinically apparent features. This problem is compounded by the fact that early and correct diagnosis is key to mitigating the effects of HH on patients. Untreated, HH can result in iron overload, which in turn may cause significant liver, heart, and endocrine damage. Therefore, this study will fill a gap in the research and in practice by developing an improved model of HH diagnosis and screening utilizing patient claims records and diagnosed comorbidities. This study utilized likelihood ratios and LASSO regression to reduce the feature set to develop manageable models. The results indicated effective models can be developed utilizing patient claims data to detect and diagnose Hereditary Hemochromatosis.

description: This thesis examines the sound system of neologisms created in fantasy literature. I noted all neologisms in fantasy novels picked from specific award lists and recommended reading lists, then transcribed the words phonetically. After transcribing, I examined all of the words to see what they have in common with each other and what phonological rules they follow. Using the data thus gathered, I drew the conclusion that fantasy neologisms do, in fact, follow phonological rules similar to those that English language speakers follow.

description: Not long after the laser was invented, it has been marked as a candidate source of strong, high-frequency electromagnetic radiation for acceleration of particles. Indeed, while the complex particle accelerator facilities today are an astonishing culmination of decades of work contributed by generations of physicists, engineers, and a host of scientists, new trends and acceleration technologies have been recently proposed and demonstrated. One of these technologies involves the miniaturization of particle accelerators, which is achieved by replacing the radio-frequency electromagnetic fields accelerating the particles with fields in the optical frequency range, using lasers. This entails using nanophotonics structures to provide the required field distribution. Recently, individual elements towards the nanophotonics counterpart of RF accelerators have been demonstrated. Similarly, active electron transport through such a structure has been shown, which was based on the concept of alternating phase focusing. In this contribution, we discuss and augment on the recently-demonstrated principle of alternating phase focusing using optical frequencies, and provide new insights from relevant simulations and experiments. In particular, we show how to identify possible imprecisions and parasitic effects from time delay scans and discuss how the transmission of electrons through the nanometric structure depends on the temporal overlap between electron and laser pulses, and show how the incidence angle of the electron beam can affect the measured transmission of electrons through the structure.

description: Emotion classification through EEG signals plays a significant role in psychology, neuroscience, and human-computer interaction. This paper addresses the challenge of mapping human emotions using EEG data in the Mapping Human Emotions through EEG Signals FG24 competition. Subjects mimic the facial expressions of an avatar, displaying fear, joy, anger, sadness, disgust, and surprise in a VR setting. EEG data is captured using a multi-channel sensor system to discern brain activity patterns. We propose a novel two-stream neural network employing a Bi-Hemispheric approach for emotion inference, surpassing baseline methods and enhancing emotion recognition accuracy. Additionally, we conduct a temporal analysis revealing that specific signal intervals at the beginning and end of the emotion stimulus sequence contribute significantly to improve accuracy. Leveraging insights gained from this temporal analysis, our approach offers enhanced performance in capturing subtle variations in the states of emotions.

description: Algorithmic bias is a major issue in machine learning models in educational contexts. However, it has not yet been studied thoroughly in Asian learning contexts, and only limited work has considered algorithmic bias based on regional (sub-national) background. As a step towards addressing this gap, this paper examines the population of 5,986 students at a large university in the Philippines, investigating algorithmic bias based on students' regional background. The university used the Canvas learning management system (LMS) in its online courses across a broad range of domains. Over the period of three semesters, we collected 48.7 million log records of the students' activity in Canvas. We used these logs to train binary classification models that predict student grades from the LMS activity. The best-performing model reached AUC of 0.75 and weighted F1-score of 0.79. Subsequently, we examined the data for bias based on students' region. Evaluation using three metrics: AUC, weighted F1-score, and MADD showed consistent results across all demographic groups. Thus, no unfairness was observed against a particular student group in the grade predictions.

description: The increasingly stringent data privacy regulations limit the development of person re-identification (ReID) because person ReID training requires centralizing an enormous amount of data that contains sensitive personal information. To address this problem, we introduce federated person re-identification (FedReID) -- implementing federated learning, an emerging distributed training method, to person ReID. FedReID preserves data privacy by aggregating model updates, instead of raw data, from clients to a central server. Furthermore, we optimize the performance of FedReID under statistical heterogeneity via benchmark analysis. We first construct a benchmark with an enhanced algorithm, two architectures, and nine person ReID datasets with large variances to simulate the real-world statistical heterogeneity. The benchmark results present insights and bottlenecks of FedReID under statistical heterogeneity, including challenges in convergence and poor performance on datasets with large volumes. Based on these insights, we propose three optimization approaches: (1) We adopt knowledge distillation to facilitate the convergence of FedReID by better transferring knowledge from clients to the server; (2) We introduce client clustering to improve the performance of large datasets by aggregating clients with similar data distributions; (3) We propose cosine distance weight to elevate performance by dynamically updating the weights for aggregation depending on how well models are trained in clients. Extensive experiments demonstrate that these approaches achieve satisfying convergence with much better performance on all datasets. We believe that FedReID will shed light on implementing and optimizing federated learning on more computer vision applications.

Although in general the origin of the emission is robustly identified as synchrotron radiation from the shock-accelerated electrons, many aspects remain poorly constrained, such as the role of inverse Compton emission, the particle acceleration mechanism, the properties of the environment and of the GRB jet itself. The extension of the afterglow emission into the TeV band has been discussed and theorized for years, but has eluded for a long time the observations. Recently the Cherenkov telescopes MAGIC and H.E.S.S. have unequivocally proven that afterglow radiation is produced also above $100$\,GeV, up to at least a few TeV. The accessibility of the TeV spectral window will largely improve with the upcoming facility CTA ({the} Cherenkov Telescope Array). In this review article, we first revise the current model for afterglow emission in GRBs, its limitations and open issues. Then we describe the recent detections of very high energy emission from GRBs and the origin of this radiation. Implications on the understanding of afterglow radiation and constraints on the physics of the involved processes will be deeply investigated, showing how future observations, especially {by} the CTA Observatory, are expected to give a key contribution in improving our comprehension of such elusive sources.

description: Integrated sensing and communication (ISAC) opens up new service possibilities for sixth-generation (6G) systems, where both communication and sensing (C&S) functionalities co-exist by sharing the same hardware platform and radio resource. In this paper, we investigate the waveform design problem in a downlink multi-user and multi-target ISAC system under different C&S performance preferences. The multi-user interference (MUI) may critically degrade the communication performance. To eliminate the MUI, we employ the constructive interference mechanism into the ISAC system, which saves the power budget for communication. However, due to the conflict between C&S metrics, it is intractable for the ISAC system to achieve the optimal performance of C&S objective simultaneously. Therefore, it is important to strike a trade-off between C&S objectives. By virtue of the multi-objective optimization theory, we propose a weighted Tchebycheff-based transformation method to re-frame the C&S trade-off problem as a Pareto-optimal problem, thus effectively tackling the constraints in ISAC systems. Finally, simulation results reveal the trade-off relation between C&S performances, which provides insights for the flexible waveform design under different C&S performance preferences in MIMO-ISAC systems.

description: Abstract

This study aimed to create an optimal Artificial Neural Network (ANN) model for recognizing document identity patterns. Various experiments were conducted with different numbers of neurons in the hidden layer to determine the best ANN model that provided optimal accuracy in data validation and testing. During the training process, 70% of the research data (980 data points) were used as training data, whereas the remaining 30% (420 data points) were used as testing data. Each variation in the number of neurons in the hidden layer was evaluated to determine the performance and accuracy of the resulting model. The experimental results demonstrated that the number of neurons in the hidden layer significantly influenced the pattern recognition accuracy. Initially, an increase in the number of neurons resulted in a decrease in the Mean Squared Error (MSE) value and an increase in accuracy in the validation and testing stages. However, no significant improvement was observed when the number of neurons exceeded 30. A summary of the experimental results showed that the ANN model with 30 neurons in the hidden layer provided optimal performance with a validation accuracy of 99.49% and a testing accuracy of 97.62%. In the development of document control applications, this model was chosen due to its stable performance and relatively short computation time. Based on the results and analysis of this experiment, it was concluded that the number of neurons in the hidden layer of the ANN affected the performance of the model. To obtain optimal performance, the number of neurons in the hidden layer should not exceed 30. A model with 30 neurons in a hidden layer is the best choice for document identity pattern recognition, based on computational accuracy and time efficiency.
title: "I Can Feel My Grin Turn to a Grimace": From the Sophiatown Shebeens to the Streets of Soweto on the pages of Drum, The Classic, New Classic, and Staffrider

description: This thesis uses a comparative framework of historical analysis to investigate four South African literary magazines printed between 1951 and 1983. Drum, The Classic, New Classic, and Staffrider function as platforms for the exhibition of writing that depicted the authors‘ interpretations of the ―black experience‖ in South Africa. In the process, these writers probed controversial race relations, contradictions of ―nation‖ and ―community,‖ and rival strategies of protest and negotiation. These four magazines formed a distinct literary lineage of quotidian narratives and trope characters, yet the variations within this lineage reveal how these writers responded to the social and political exigencies of life under apartheid in South Africa. On the pages of these magazines writers publicly debated their place within a racially stratified society, and fictional characters negotiated a world remarkably similar to that of their creators. Through analysis of divisions within black liberation movements, the emergence of Black Consciousness, and the assertion of youth power in the Soweto Uprising of 1976, this thesis seeks to demonstrate that under apartheid, there were no clearly defined spheres of politics or art. Consequently, in their quest for relevancy, many of these writers found themselves producing politicized fiction as they articulated the frustrations and aspirations of their readers. In doing so, literary artists, political activists, and fictional characters revealed a common desire for the comforts of community while simultaneously contesting the criteria for membership.

title: The Alternative Three-Factor Model: Evidence from the German Stock Market

description: This article applies the alternative three-factor model introduced by Chen / Novy-Marx / Zhang (2010) to the German stock market for the sample period of 2004 through 2015. We construct two new factors INV („investment") and ROA („return on assets") for companies listed on the highest segment of the Frankfurt Stock Exchange, and examine whether they can explain various stock market anomalies using linear time series regressions. Our results reveal that the theoretical assumptions of the model are valid for the German stock market. Firms with higher investments generally exhibit lower returns, while more profitable firms exhibit higher returns. However, we find that the alternative three-factor model does not explain capital market anomalies in the German market better than the factors of the traditional Fama / French (1993) three-factor model.

description: We developed an analytical theoretical method to determine the microscopical structure of weakly to moderately sheared colloidal suspensions in dilute conditions. The microstructure is described by the static structure factor, obtained by solving the stationary two-body Smoluchowski advection-diffusion equation. The singularly perturbed PDE problem is solved by performing an angular averaging over the extensional and compressing sectors and by the rigorous application of boundary-layer theory (intermediate asymptotics). This allows us to expand the solution to a higher order in Péclet with respect to previous methods. The scheme is independent of the type of interaction potential. We apply it to the example of charge-stabilized colloidal particles interacting via the repulsive Yukawa potential and study the distortion of the structure factor. It is predicted that the distortion is larger at small wavevectors $k$ and its dependence on $Pe$ is a simple power law. At increasing $Pe$, the main peak of the structure factor displays a broadening and shift towards lower $k$ in the extensional sectors, which indicates shear-induced spreading out of particle correlations and neighbor particles locally being dragged away from the reference one. In the compressing sectors, instead, a narrowing and shift towards high $k$ is predicted, reflecting shear-induced ordering near contact and concomitant depletion in the medium-range. An overall narrowing of the peak is also predicted for the structure factor averaged over the whole solid angle. Calculations are also performed for hard spheres, showing good overall agreement with experimental data. It is also shown that the shear-induced structure factor distortion is orders of magnitude larger for the Yukawa repulsion than for the hard spheres.
