Abstract: A number of simulation-based methods, such as Gillespie's algorithm or stochastic differential equations, provide a way to simulate data generated by a system following a model. By contrast to forward simulation-based strategies, to deduce dynamical laws or parameters from data requires inverse strategies such as Bayesian methods. Likelihoods are a central object of Bayesian modeling whose computation demand significant time and memory resources. To facilitate the task of evaluating likelihoods, these can be approximated using neural networks trained to emulate forward simulations. Here we use such methods for problems of relevance in biophysics from the protein to the cellular scale.

Abstract: Proteins are essential molecules in living cells. Disrupted intracellular protein homeostasis could lead to many diseases, such as cancers and Alzheimer’s disease. Translation, the birth of proteins, is a critical step for maintaining protein homeostasis. Understanding the regulation mechanisms of translation helps us to explore novel therapeutics. Recently, the use of repeat short epitope tags combined with complementary fluorescent antibody fragments, such as the spaghetti monster/Fabs and the SunTag/scFv imaging systems, has made it possible to visualize translation dynamics live at single mRNA level. By applying these tagging systems, many novel mechanisms of translation have been uncovered. However, the lack of comparable and orthogonal genetically encodable tagging systems has made applications that require multicolor imaging challenging. To address this challenge, we developed a panel of orthogonal genetically encodable tagging systems with comparable lengths of epitope tags: the HA tag (9 aa), the FLAG tag (8 aa), and a novel UTag (11 aa). For this, we grafted complementary determining regions or loops of the antibodies to a stable single-chain variable fragment (scFv) scaffold that folds correctly in the reduced intracellular environment. After the loop grafting, the binding of the wild-type scFvs was rescued in living cells. Our FRAP data suggest the binding of these three tagging systems is comparably tight. We believe these favorable properties will make these tagging systems useful tools in multicolor imaging applications.

Abstract: Cryptocurrencies and blockchain have become a global phenomenon transforming peo-ple's relationships with technology and offering innovative tools for businesses and individuals to strive in a digital age. However, little is still known about the main drivers of cryptocurrency ownership, especially in emerging markets. Based on a representative online survey among 573 Brazilian digital platform investors, we find that crypto investors tend to be young, male, more tol-erant to risk, less optimistic in their economic views, and consider themselves as ‘better’ investors compared to non-crypto online traders. While crypto and non-crypto investors have similar edu-cational backgrounds, our results show that cryptocurrency literacy positively and strongly relates to cryptocurrency ownership and intentions to invest in cryptocurrency. A gender gap among cryptocurrency investors has been confirmed. The findings further suggest that sophisticated in-vestors are more likely to hedge pessimistic economic expectations using cryptocurrency than their unsophisticated peers. We also find significant heterogeneity among cryptocurrency investors (e.g., early x late adopters) on attitudes and beliefs. The insights into digital investors' intentions to invest in cryptocurrency can be valuable for policymakers in designing strategies for the broader adoption of digital assets in the era of a decentralized economy, considering the planned adoption of CBDC in Brazil.

Abstract: This research aims to analyze the sentiment of social media users towards the election. The author collected data in this research through a literature study and observation. The author uses a classification method with the Naïve Bayes Classifier Algorithm and Support Vector Machine to analyze sentiment results. Next, this research extracts word assessment features using TextBlob, which changes text into positive or negative classes. Based on the research results, after going through the text preprocessing stage of more than 15,000 tweets, 11,000 clean tweets were obtained, which were then labelled using the text blob library in Python. The labelling results show that 4,000 tweets are positive, and the rest are harmful, indicating that most social media users' sentiment towards the election is positive. Words that often appear in the positive class express support and confidence in implementing elections that are considered honest and fair. On the other hand, words in the negative class reflect negative sentiment towards implementing elections, which are considered unsuccessful and time-consuming. The Naïve Bayes method provides accuracy, precision, and recall values of 85%, 80%, and 75%. In the Support Vector Machine method, testing is carried out with three kernels (linear, RBF, and poly), where the poly kernel with the best parameter values C is ten and degree is 1 produces the highest accuracy, precision, and recall of 90%, 90%, and 85%, respectively.

Abstract: Training general-purpose vision models on purely sequential visual data, eschewing linguistic inputs, has heralded a new frontier in visual understanding. These models are intended to not only comprehend but also seamlessly transit to out-of-domain tasks. However, current endeavors are hamstrung by an over-reliance on colossal models, exemplified by models with upwards of 3B parameters, and the necessity for an extensive corpus of visual data, often comprising a staggering 400B tokens. In this paper, we delve into the development of an efficient, autoregression-based vision model, innovatively architected to operate on a limited dataset. We meticulously demonstrate how this model achieves proficiency in a spectrum of visual tasks spanning both high-level and low-level semantic understanding during the testing phase. Our empirical evaluations underscore the model's agility in adapting to various tasks, heralding a significant reduction in the parameter footprint, and a marked decrease in training data requirements, thereby paving the way for more sustainable and accessible advancements in the field of generalist vision models.

Abstract: This paper proposes an extension of the SysML safety semantic approach to address the lack of safety and reliability semantics and the support for safety and reliability analysis of the model in SysML. On this basis, fault tree generation and analysis are performed. The method first adds semantic information about fault tree and redundant module to the model using the Stereotype extension mechanism, integrating design data and safety data through an extended configuration file in the SysML model. Secondly, sub-mode decomposition of Internal Block Diagram is conducted, and fault mode recognition is described in relation to fault tree mapping. Based on this, a search is conducted on the SysML model to obtain necessary information for fault tree generation, followed by an analysis of the generated fault tree.

Abstract: Accurately controlling the quantum coherence of photons is pivotal for their applications in quantum sensing and quantum imaging. Here, we propose the utilization of quantum entanglement and local phase manipulation techniques to control the higher-order quantum coherence of photons. By engineering the spatially varying phases in the transverse plane, we can precisely manipulate the spatial structure of the second-order coherence function of entangled photon pairs without changing the photon intensity distribution of each photon. Our approach can readily be extended to higher-order quantum coherence control. These results could potentially stimulate experimental research and applications of optical quantum coherence.

Abstract: From the birth of video games until today, players have interacted with video games via controllers. However, with the maturation of biofeedback technology, players can now obtain brand-new interactive gaming experiences. The commands input to the game are no longer merely from the buttons on the game controller. Biofeedback technology uses sensors to read the physiological signals of the game player, enabling the game to directly perceive the player’s physiological state through data such as heart rate, eye movement, and facial emotions when they are playing the game and match the next step in the game progress. Compared to traditional games, video games based on biofeedback technology provide specific, real-time feedback to individual players, creating an immersive gaming experience through embodied interactions, guiding game designers better. When artificial intelligence technology combines with biofeedback technology, AI will learn and analyze a large amount of user physiological data collected by biofeedback technology, making the interaction between the game and the players more intelligent and personalized.

Abstract: With the rising popularity of virtual worlds, the importance of data-driven parametric models of 3D meshes has grown rapidly. Numerous applications, such as computer vision, procedural generation, and mesh editing, vastly rely on these models. However, current approaches do not allow for independent editing of deformations at different frequency levels. They also do not benefit from representing deformations at different frequencies with dedicated representations, which would better expose their properties and improve the generated meshes' geometric and perceptual quality. In this work, spectral meshes are introduced as a method to decompose mesh deformations into low-frequency and high-frequency deformations. These features of low- and high-frequency deformations are used for representation learning with graph convolutional networks. A parametric model for 3D facial mesh synthesis is built upon the proposed framework, exposing user parameters that control disentangled high- and low-frequency deformations. Independent control of deformations at different frequencies and generation of plausible synthetic examples are mutually exclusive objectives. A Conditioning Factor is introduced to leverage these objectives. Our model takes further advantage of spectral partitioning by representing different frequency levels with disparate, more suitable representations. Low frequencies are represented with standardised Euclidean coordinates, and high frequencies with a normalised deformation representation (DR). This paper investigates applications of our proposed approach in mesh reconstruction, mesh interpolation, and multi-frequency editing. It is demonstrated that our method improves the overall quality of generated meshes on most datasets when considering both the $L_1$ norm and perceptual Dihedral Angle Mesh Error (DAME) metrics.

Abstract: We adapt the classical notion of learning from text to computable structure theory. Our main result is a model-theoretic characterization of the learnability from text for classes of structures. We show that a family of structures is learnable from text if and only if the structures can be distinguished in terms of their theories restricted to positive infinitary $\Sigma_2$ sentences.

Abstract: We analyze the capabilities of Transformer language models on learning discrete algorithms. To this end, we introduce two new tasks demanding the composition of several discrete sub-tasks. On both training LLaMA models from scratch and prompting on GPT-4 and Gemini we measure learning compositions of learned primitives. We observe that the compositional capabilities of state-of-the-art Transformer language models are very limited and sample-wise scale worse than relearning all sub-tasks for a new algorithmic composition. We also present a theorem in complexity theory, showing that gradient descent on memorizing feedforward models can be exponentially data inefficient.
