Real patterns, the predictive mind, and the cognitive construction of the manifest image
(Springer Nature, 2025-10-22) Gładziejewski, Paweł
Dennett famously argued that constituents of the manifest (commonsense) image of the world are real patterns, where patternhood is grounded in data compressibility. This paper builds upon Dennett’s original formulation by connecting it with recent work in computational cognitive (neuro)science. The aim is to use the notion of real patterns to shed light on the genealogy of the ontological commitments of the common sense, arguing that the processes by which humans learn and update internal models of the environment can be understood as extracting real patterns from sensory data. In particular, I trace a conceptual and mathematical progression linking Kolmogorov-Chaitin complexity and minimum description length to predictive coding, Bayesian inference, and predictive processing accounts of cognition. Then, I argue that this cognitive interpretation of Dennett’s core idea suggests a structuralist (and Kantian) perspective on the relationship between mind and world, whereby the manifest image represents a structure present in sensory data. The paper concludes by sketching how this cognitive form of real-pattern view connects with (and possibly illuminates) metaphysical debates regarding the reality of two types of commonsense entities: selves and ordinary physical objects.
Interconnected Cities, Integrated Markets: Exploring the Impact of Transport Networks on Labor Market Integration in the Yangtze River Delta, China
(Wiley, 2025) Liu, Xueqing; Derudder, Ben; Wang, Bo; Witlox, Frank
This paper examines the impact of cities' network connections on regional labor market integration in megacity‐regions. By applying a panel model to data for the Yangtze River Delta between 2014 and 2021, we analyze the impact of transport networks on labor market integration and explore the (potential) mechanisms in terms of network externalities. Our empirical analysis suggests a positive association between connectivity in transport networks and labor market integration. We also observe evidence of indirect effects: transport networks allow cities to benefit from network externalities associated with effective labor matching, specifically by reducing geographical distance restrictions and lowering matching costs, thus contributing to the increased integration of labor markets. We reflect on the broader implications of our empirical findings for regional development strategies and discuss possible avenues for further research.

Development of a hydrophilic interaction-based procedure for the extraction, separation, and determination of therapeutic oligonucleotides
(Elsevier, 2025-10-19) Vosáhlová, Zuzana; Bocian, Szymon; Studzińska, Sylwia
Background: For analyzing oligonucleotide impurities and metabolites in serum samples, where mass spectrometry detection is essential, hydrophilic interaction liquid chromatography utilizing fully mass spectrometry compatible mobile phases is the best choice. However, reliable analysis must be preceded by a reliable extraction method providing sufficient and repeatable recoveries. Thus, this work aimed to develop a simple and repeatable methodology for extracting and analyzing modified oligonucleotides differing in length (4mer-14mer), both under hydrophilic interaction conditions.
Results: A comprehensive retention study examining the effects of mobile phase composition and temperature on retention and peak shape was conducted for the zwitterionic and amide columns. Based on the results, the amide column was chosen for further study, mainly because the zwitterionic column does not permit elution of longer oligonucleotides (>10mer). In addition, the amide column exhibits greater robustness (minor effects of tested parameters on chromatographic performance), which ensures higher repeatability. The optimization of mass spectrometry parameters was performed to obtain the highest possible sensitivity, which is well well-known issue because of adducts formation. A validated procedure was applied to analyze enriched serum extracts - a newly synthesized amide-based sorbent was used for the dispersive solid-phase extraction. The conditions for adsorption and desorption, which are driven by a weak ion-exchange mechanism and thus by pH change, were optimized to obtain the highest recoveries.
Significance: A fully hydrophilic interaction-based procedure was utilized for the first time f extraction and analysis of a mixture of 5 modified oligonucleotides differing in length from enriched serum. This method proved to be simple, repeatable, and provides recoveries higher than 75% (RSD <5%).
An intercity investment network dataset of China based on the enterprise registration records (2000–2020)
(Nature Research, 2025) Shu, Tianheng; Yang, Shuo; Cheng, Guangyu; Ren, Yitian; Ren, Yitian; Shi, Fangchen; Derudder, Ben; Liao, Xia
Intercity investment activities among enterprises reflect the flow of capital between cities, thereby directly illustrating the economic connections between them. However, there is currently no publicly available dataset that captures this important feature. In this study, we introduce an intercity investment network (IIN) dataset for China, covering the period from 2000 to 2020, based on 17,273,411 large-scale enterprise registration records. The dataset represents 367 cities as nodes, with investment frequency between cities serving as edge weights to construct both directed and undirected networks. It captures the spatiotemporal patterns of China’s IIN, highlighting dynamic changes in economic connectivity over time and space. The dataset aligns closely with urban networks formed by China’s population mobility and the economic gravity model, is consistent with official records and existing research findings, and satisfies the distance decay effect, thus validating its scientific reliability.
This dataset provides unique opportunities for exploring economic interactions and functional organization between cities, and advancing urban network research in China.
