Summary: The author presents a new mentalistic reformulation of the measurement problem in quantum mechanics, suggesting that it is essentially a determinate-experience problem. The paper clarifies that the well-known measurement problem is a mathematical consequence of quantum theory's formalism and that its mentalistic variant does not capture the relevant causes behind this issue. The essay also discusses how Bohmian mechanics and GRW theories offer clear explanations for the localization of macroscopic objects without human intervention, distinguishing between the measurement problem and the determinate-experience problem.

Summary: This paper discusses the importance of Bohmian mechanics and a primitive ontology, emphasizing the issue of observability in quantum theories and explaining why Einstein's epistemological model supports the use of a primitive ontology.

Summary: This paper explores the structuralist approach to interpreting the wave function as a physical structure within Bohmian mechanics, using the framework of Ontic Structural Realism (OSR). The author discusses how different versions of OSR can be applied to the interpretation of Bohmian mechanics and evaluates these alternatives. Additionally, a novel structuralist interpretation of Bohmian mechanics based on the framework of metaphysical coherentism is proposed.

Summary: This study utilizes artificial intelligence methods and deep learning models to model the buckling behavior of notched beams. The model, called DeepBuckle, can qualitatively and quantitatively learn the buckling behavior of homogeneous polymer beams and predict new designs that produce specific buckling behaviors. Importantly, this approach can generalize to beams made of complex composite foam materials without requiring additional computational resources or knowledge of material characteristics. The method reported here can be easily transferred to other applications and is suitable for fundamental research and educational settings.

Summary: This paper argues against the proposal that spacetime or spatiotemporal relations are not fundamental, pointing out that such claims need rigorous scrutiny in physics. The paper suggests that if spacetime is to be recovered in a theory that denies its fundamental nature, standard functionalism cannot serve as a model in this case.

Summary: The paper discusses Bell's Everett theory and develops TBM theory further, which considers the system of all particles in the universe performing random jumps in configuration space. Unlike traditional Bohmian Mechanics, TBM theory does not assume continuous particle trajectories and deterministic dynamics but is defended as an empirically adequate and coherent quantum theory. Furthermore, it argues for the sequential existence of Everettian worlds in TBM, with quasi-classical histories persisting in a temporally coarse-grained sense while individual particles themselves cease to persist.

Summary: This study measures the spatial distribution of track initiation in a diffusion cloud chamber and considers its implications for the quantum measurement problem. The results may suggest a modification to Born's rule at small wave function scales, with potential implications for detecting rare events. It introduces two candidate modifications to the Born rule and highlights the significance of track distributions in cloud chambers for probing the foundations of quantum mechanics.

Summary: This conceptual paper proposes an organizing framework for qualitative research in complexity studies in management, emphasizing the importance of capturing, understanding, and articulating complexity as an empirical tendency rather than a measurement-driven orientation. It also argues that the pursuit of numerical precision and generalizable truthfulness is unnecessary in providing practically meaningful and realistic recommendations in the context of complexity.

Summary: This study presents a new method for measuring DNA pressure in viral capsids, which does not require a specific viral receptor. By measuring DNA pressure in bacteriophages with varying DNA packing densities, an empirical equation is derived that accurately predicts the relation between capsid pressure and packaged DNA density.

Summary: This article investigates the measurement problem in quantum mechanics from two aspects. It identifies the classicality of apparatus postulate as the source of the problem and introduces the concept of microscopic quantum jump to explain the measurement process. By adopting the postulate of the microscopic quantum jump and discarding the classicality of apparatus postulate, a consistent measurement theory has been constructed.

Summary: The paper introduces an alternative two-boundary concept called the surjective mapping conjecture to explain the measurement path of the quantum-time universe. This concept views quantum time as running forward on the wave-function side and backward on the complex conjugate side, with fixed arbitrary conditions determining the measurement path.

Summary: The Aristotelian philosophy of nature rejects the modern bias towards the microscopic in order to delve into the mysteries of the quantum world. The author defends an Aristotelian model by incorporating quantum chemistry and recent research on the measurement problem, ultimately developing a realist, holistic, and hylomorphic version of the Copenhagen interpretation. The critique of non-hylomorphic theories, such as Bohmian mechanics, Everettianism, and GRW mass-density, highlights the attribution of fundamental causal powers to human observers and their instruments.

Summary: Wallace argues that popular approaches to the measurement problem cannot be extended to relativistic quantum mechanics and quantum field theory. He suggests that only unitary-only approaches are currently viable, but they face serious epistemic problems. Therefore, finding a viable solution that can be extended to relativistic quantum mechanics remains an urgent outstanding problem. The article explores the possibility of a single-world realist approach without dynamical, precisely-defined microscopic beables as a solution to the measurement problem.

Summary: Bub and Pitowsky claimed that there are in fact two measurement problems, the big and the small, which have different degrees of relevance in the framework of an information-theoretic view of quantum mechanics. They also argue that the analysis of quantum measurement becomes a problem only if unnecessary assumptions, which they consider as dogmas, are made. However, I criticize their unconventional stance on the measurement problem and point out that their arguments rely on a controversial extension concerning the foundations of special relativity in the quantum realm.

Summary: The theory of Selected Effects explains function in biology as the effect of past traits that contributed to the current existence of a trait. However, it is critiqued for its inability to account for the introduction of new functions and for neglecting the physical work involved in function.
