Umysł ucieleśniony – haptyczność w filozofii Berkeleya
Authors: Michalski Rafał Andrzej 
Published: February 2025

In this article, I aim to demonstrate that G. Berkeley’s immaterialism is founded on the concept of an embodied mind that extends into the realm of sensory experience. On the level of theological discourse, Berkeley also employs the category of the soul as an inextensible, atemporal substance. However, this metaphysical approach serves as a necessary assumption that, while completing the theoretical framework, does not play a significant role in psychological analysis. The second purpose of my interpretation is to substantiate the thesis that the sense of touch is the basis of the soul’s activity and delineates the limits of its accessible experience.

On the linear disjunctive decomposition of a p-logic function into a product of functions
Authors: Cheremushkin Aleksandr V. 
Published: February 2025

Abstract
Let p be a prime number, p ≥ 3. We consider the set of decompositions of a p-logic function into a product of functions with disjoint subsets of variables obtained by means of linear substitutions of arguments. Each decomposition of this kind is associated with a decomposition of the vector space into a direct sum of subspaces. We present conditions under which such space decomposition is unique up to rearrangement of subspaces. Also, a criterion for such product to be balanced is given.
Data on Repeated Offerings in the German Housing Market Based on RWI-GEO-RED
Authors: Breidenbach Philipp , Hoernig Lukas , Wiebe Thorben 
Published: February 2025

Abstract
This paper introduces a repeated-sales algorithm tailored for the German real estate market, addressing the lack of such data. Utilizing the dataset RWI-GEO-RED from FDZ Ruhr at RWI, which exploits data from ImmobilienScout24.de, the algorithm classifies repeat-sales and repeat-rent listings, overcoming challenges like measurement errors and deviations in property characteristics. The methodology, based on nearest centroid classification, ensures accurate clustering of similar listings. The paper compares the new repeated-sales indices with the traditional hedonic price index, revealing more conservative estimates of rent growth. Additionally, the data’s panel structure allows for detailed analysis of unit-level dynamics and mispricing. The study highlights the advantages of this approach and suggests potential research avenues, providing a valuable tool for economists and policymakers to assess housing market trends in Germany.

Published: February 2025

Abstract

Context
Following the transition to a single graduate medical education (GME) accreditation system in 2020, leaders at American Association of Colleges of Osteopathic Medicine (AACOM) were interested in learning more about the research being done about osteopathic medical education leading up to that point in time.

Objectives
The objective of this scoping review was to identify trends in undergraduate and graduate osteopathic medical education and to determine where this information was being disseminated and the institutions who were creating the content.

Methods
Searches were conducted in eight databases: PubMed (National Center for Biotechnology Information [NCBI]), MEDLINE (Ovid), Embase (Elsevier), Cumulative Index to Nursing and Allied Health Literature ([CINAHL], EBSCO), Education Research Complete (EBSCO) OSTMED.DR, Education Resources Information Center ([ERIC], Ovid), and Scopus (Elsevier). Gray literature sources were also identified. All 10 authors were involved in the search. Search terms were identified by utilizing Medical Subject Headings (MeSH), the Yale MeSH Analyzer, and through consultation with an expert searcher. Sources were excluded if they were not in English, were based outside of the United States, did not fit in the date range of being published between 2010 and 2020, and included information on COVID-19. The research team conducted title/abstract screening based on the inclusion and exclusion criteria.

Results
A total of 8,083 articles were identified and included through searches, ending in a total of 1,203 articles after full-text screening. Most sources for this osteopathic medical education review were journal articles (n=505) and conference proceedings (n=482). A total of 23 trends were identified, with the top three being residency (n=318), curriculum (n=235), and pedagogy (n=178). None of the other 23 primary trends were above 6.9 %.

Conclusions
Osteopathic medical education trends from 2010 to 2020 were primarily focused on residency, curriculum, and pedagogy. This information was disseminated evenly between published journal articles and conference presentations, and osteopathic institutions that have existed longer and have established research track records were more likely to publish and share information in this area.

Authors: Slinkov Grigorii , Becker Steven , Englund Dirk , Stiller Birgit 
Published: February 2025

Abstract
Optical neural networks have demonstrated their potential to overcome the computational bottleneck of modern digital electronics. However, their development towards high-performing computing alternatives is hindered by one of the optical neural networks’ key components: the activation function. Most of the reported activation functions rely on opto-electronic conversion, sacrificing the unique advantages of photonics, such as resource-efficient coherent and frequency-multiplexed information encoding. Here, we experimentally demonstrate a photonic nonlinear activation function based on stimulated Brillouin scattering. It is coherent and frequency selective and can be tuned all-optically to take LeakyReLU, Sigmoid, and Quadratic shape. Our design compensates for the insertion loss automatically by providing net gain as high as 20 dB, paving the way for deep optical neural networks.

Published: February 2025

Abstract
Among the approaches in three-dimensional (3D) single molecule localization microscopy, there are several point spread function (PSF) engineering approaches, in which depth information of molecules is encoded in 2D images. Usually, the molecules are excited sparsely in each raw image. The consequence is that the temporal resolution has to be sacrificed. In order to improve temporal resolution and ensure localization accuracy, we propose a method, SH-CS, based on light needle excitation, detection system with single helix-point spread function (SH-PSF), and compressed sensing (CS). Although the SH-CS method still has a limitation about the molecule density, it is suited for relatively dense molecules. For each light needle scanning position, an SH image of excited molecules is processed with CS algorithm to decode their axial information. Simulations demonstrated, for random distributed 1–15 molecules in depth range of 4 μm, the axial localization accuracy is 12.1–73.5 nm. The feasibility of this method is validated with a designed 3D sample composed of fluorescent beads.

Published: February 2025

Abstract
Unitarity serves as a fundamental concept for characterizing linear and conservative wave phenomena in both classical and quantum systems. Developing platforms that perform unitary operations on light waves in a universal and programmable manner enables the emulation of complex light–matter interactions and the execution of general-purpose functionalities for wave manipulations, photonic computing, and quantum circuits. Recently, numerous approaches to implementing programmable photonic unitary circuits have been proposed and demonstrated, each employing different design strategies that distinctly impact overall device performance. Here, we review foundational design principles and recent achievements in the implementation of programmable photonic unitary circuits, with a particular focus on integrated photonic platforms. We classify the design strategies based on the dimensionality of nontrivial unit operations in their building blocks: lower-dimensional unitary units, such as SU(2) operations, and higher-dimensional ones, such as Fourier transforms. In each category, recent efforts to leverage alternative physical axes, such as the temporal and frequency domains, to address scalability challenges are also reviewed. We discuss the underlying concepts, design procedures, and trade-offs of each design strategy, especially in relation to light-based computing.

Abstract
Empowering nanophotonic devices via artificial intelligence (AI) has revolutionized both scientific research methodologies and engineering practices, addressing critical challenges in the design and optimization of complex systems. Traditional methods for developing nanophotonic devices are often constrained by the high dimensionality of design spaces and computational inefficiencies. This review highlights how AI-driven techniques provide transformative solutions by enabling the efficient exploration of vast design spaces, optimizing intricate parameter systems, and predicting the performance of advanced nanophotonic materials and devices with high accuracy. By bridging the gap between computational complexity and practical implementation, AI accelerates the discovery of novel nanophotonic functionalities. Furthermore, we delve into emerging domains, such as diffractive neural networks and quantum machine learning, emphasizing their potential to exploit photonic properties for innovative strategies. The review also examines AI’s applications in advanced engineering areas, e.g., optical image recognition, showcasing its role in addressing complex challenges in device integration. By facilitating the development of highly efficient, compact optical devices, these AI-powered methodologies are paving the way for next-generation nanophotonic systems with enhanced functionalities and broader applications.
Formation of the State Legislation in the Field of Popularization of Science in Libraries
Authors: Yudina I. G. 
Published: February 2025

At present, the problem of history of the State policy for the promotion of science is of interest to many scientists. However, the features of the origin and formation of the domestic legislation in the sphere of popular scientific knowledge promotion through libraries are not enough studied. The purpose of the study was to identify and analyze the most significant legal documents in the field of science and technology popularization, including those addressed to libraries. The source base was an amount of legislative acts from 1917 to 1941. As the result of the study, the author determined that the development of the domestic system of the State regulation of popularization of science began in the early years the Soviet state existence. The dissemination of scientific knowledge into the society through the system of non-formal education was regarded as the necessary means of awakening the activity of masses in the process of their participation in the Cultural Revolution, as well as the restoration and construction of the national and agricultural economy. Normative legal acts concerning libraries were developed in accordance with the national policy of the party and the government. The legislative authority charged libraries to participate in the propaganda of natural, technical, and agricultural knowledge, and to promote self-education of all citizens. The official documents of the given period recorded specific forms and methods of science popularization, including: acquisition of collections of popular science literature, preparation of lists of recommended publications, organization of traveling exhibitions, creation of scientific circles, conducting loud readings and excursions, participation in cultural and library trips, etc. The data obtained in the course of the study confirmed our assumption that in addition to serving the ideological order of the State, the librarianship in the USSR was legally entrusted with the functions of popularization of general scientific knowledge already in the early Soviet period.

Abstract

Background: Neoadjuvant chemotherapy (NACT) for non-metastatic breast cancer is often preferred over adjuvant chemotherapy to shrink tumours and facilitate surgical removal. NACT typically comprises 8 cycles over 20–24 weeks: 4 cycles of anthracycline with cyclophosphamide followed by 4 cycles of paclitaxel. After surgery, the therapeutic response is assessed histopathologically using the TNM classification, where ypT0 indicates pathological complete remission (PCR) and residual tumour cells (> ypT0) indicate non-complete remission (non-PCR). Currently, imaging techniques such as ultrasound are used during NACT to assess clinical response. Liquid biopsy-based methods may complement imaging by enabling early response monitoring. In this study, we used serum proteomics to identify marker candidates associated with PCR as early as after the second NACT cycle.
Methods: Longitudinal, retrospective serum proteomic analyses were performed on 22 breast cancer patients (11 PCR, 11 non-PCR) and 21 age-matched healthy controls. Serum samples were collected pre-therapy and after two and six NACT cycles. Proteins were analysed using liquid chromatography–tandem mass spectrometry (LC–MS/MS) following immunoaffinity depletion, trypsin digestion, tandem mass tag labelling, and fractionation. Protein quantitation was performed with MaxQuant software, and abundance analysis utilised linear models of microarray analysis. Tumour-resident expression of a candidate marker was evaluated via immunohistochemistry in an independent cohort of 37 cases.
Results: Across 84 samples, >390 proteins were consistently identified and quantified. Pre-therapy serum proteomes showed no significant differences between PCR and non-PCR groups. Longitudinal analysis revealed that serum levels of c-Met and N-cadherin could distinguish responders after the second NACT cycle with high predictive value (AUC 0.93). More pronounced changes were observed after the sixth cycle, including significant alterations in centrosomal protein, sex hormone-binding globulin, and cholinesterase levels. Additionally, N-cadherin expression was elevated in therapy-naïve tumour samples from patients achieving PCR.
Conclusions: This study highlights the potential of serum proteomics for identifying markers to assess NACT efficacy in breast cancer. Soluble N-cadherin and c-Met may serve as promising serum markers for PCR, particularly when combined with (immune)histochemical tumour characterisation.
