Dziedziczenie. Perspektywa aksjologiczna
Authors: Rafałowicz Paweł
Published: November 2024

Postawiony w książce problem sprowadza się do odtworzenia wartości chronionych i urzeczywistnianych w konstrukcji dziedziczenia przez polskiego ustawodawcę. Punktem wyjścia do podjętych rozważań jest teza, zgodnie z którą konstrukcja dziedziczenia jest osadzona w wartościach o charakterze gospodarczym i społecznym. Na kartach książki ukazano aksjologiczny wymiar poszczególnych instytucji prawa spadkowego: dziedziczenia ustawowego, dziedziczenia testamentowego i wydziedziczenia, niegodności dziedziczenia oraz wyłączenia małżonka od dziedziczenia. W każdej z tych części można odnaleźć trzy najważniejsze zagadnienia: po pierwsze – próbę ustalenia ratio legis analizowanych instytucji oraz zestaw wartości, jakie jej przyświecają lub powinny przyświecać; po drugie – ich analizę dogmatyczną, z uwzględnieniem istotnych problemów komentowanych w judykaturze i piśmiennictwie; po trzecie – ocenę regulacji w kontekście jej aksjologii.
Walczmy o usprawnienie administracji! Komisje dla usprawnienia administracji publicznej i ich rola w racjonalizacji polskiej biurowości do roku 1956
Authors: Smoczyński Marcin
Published: November 2024

Polish administration was improved through struggling. These struggles were frequent, unequal, and the "opponents" – internal and external – varied: resistant decision-makers, the conservative lobby opposed to changes and influential, unqualified officials, technical and provision difficulties, and, finally, the economic and political situation. However, from the beginning of existence of the 20th-century Polish statehood, a belief in the need to modernise the public apparatus was present. This task was largely entrusted to specially established collegial bodies called commissions for the improvement of administration, of which there were as many as fourteen in the years 1918–1956. To each of them is devoted a separate subchapter, which analyses the circumstances of their appointment, legal basis, composition and activities. However, the most important effect of the analysis was the isolation of those aspects of work that could be included in the framework of documentation management, i.e., development of office and archival norms, instructions for clerks, proposed solutions in the field of architecture and interior design, as well as office work methods. Moreover, the initial picture for later reforms was captured – the functioning of law offices at various levels after Poland regained independence and after 1945, and the implementation of the solutions developed by the commission was verified and a kind of "closing balance" was established for the office after the cessation of the activities of the colleges. A separate chapter is devoted to foreign commissions – American, British, French, Austrian, Belgian, German and Italian.

The doctoral thesis, which was the basis for writing this book, was awarded in the 14th edition of the Władysław Pobóg-Malinowski Competition for the "Best Historical Debut of the Year in the Field of Modern History" for 2021.
W stronę postliberalizmu. Filozofia społeczna i polityczna Johna Milbanka
Authors: Gużyński Jakub
Published: November 2024

In recent times, on the ground of political theory, we can observe an increasing interest in the concept of postliberalism. This term, however, has remained highly unclear – sometimes it expresses hope for the coming of a postmodern heir of the enlightenment project, at other times, fear of populist and autocratic reactionism. One can even get the impression that it constitutes only a substitute name for a theory which is yet to appear after the allegedly ineviteble twilight of immersed in the crisis liberalism.

This paper presents the Polish reader with probably the fullest expression of the idea of postliberalism which can be found in the works of John Milbank – an English theologist and theorist of politics. On the one hand, he continues the tradition of postliberal theology, bringing to the fore the narrative and political character of Christianity. On the other hand, he presents a multidimensional critique of liberalism and offers a wide-ranging programme of institutional, systemic and economic reforms. In this way, he swiftly connects the abstract theory with practical solutions, providing cohesive and incredibly original socio-political vision. Radicalism and intransigence of this vision, however, make Milibank look like an extraordinarily controversial and polarising author, and his vision of postliberal future is not free from darker sides. In consequence, one can doubt whether it actually constitutes a desired alternative to liberalism, or whether it fits into the dangerous trends of contemporary politics.
Konstrukcje absolutywne w greckim, łacińskim i gockim tekście Nowego Testamentu
Authors: Leszkiewicz Bartosz
Published: November 2024

The aim of this dissertation is the study on the absolute constructions of the original Greek New Testament and its Latin (Vulgate) and Gothic (Wulfila Bible) translations. The dissertation is divided into three parts: the theoretical part, dedicated to the history and description of absolute constructions as such; the material part, including the analysis and characteristics of the absolute constructions of the Greek NT and its oldest Gothic and Latin translations; and the part with the body of quotations. The first part of the work consists of two chapters. The first briefly presents the definition of the absolute construction adopted in the work and describes the development of the construction in the oldest languages of each individual Indo-European family. The second chapter discusses the history of linguistic reflection on absolute constructions from ancient times (Apollonius Dyscolus, 2nd century BC) to the present day (J.L. Jakielaszek, 2021). This gives an opportunity to review and analyze the views of antique, medieval, modern, and contemporary linguists on absolute constructions. In the second part of the work, three chapters correspond to the three texts studied. The first chapter deals with the original Greek text of the New Testament. It briefly presents the history of its redaction, identifies the body of absolute constructions contained in it, and then analyzes them in terms of morphology, syntax, and semantics. The second chapter is devoted to the Latin New Testament of the Vulgate. It briefly presents its genesis, identifies the body of its absolute constructions and describes them in the same way as in the case of Greek constructions. Finally, there is a comparison of the absolute constructions of both language versions. The third chapter outlines a short characterization of the Gothic Wulfila Bible, identifies which of the syntagms indicated during 200 years of research are truly absolute constructions and gives their characteristics according to the principles of the two previous chapters. The chapter concludes with a comparison of Gothic constructions with their Greek prototypes and an attempt to indicate arguments in support of the claim about the native origin of Gothic absolute constructions.
El acceso a la tierra y la informalidad de la vivienda en Yopal (Colombia): aportes para entender la informalidad urbana y los conflictos por el acceso al suelo a partir del análisis de los imaginarios sociales
Authors: Sáenz Antonio David , Vanhellemont Linus
Published: November 2024

La explicación sobre los procesos de informalidad urbana generalmente se centra en la crítica al modelo económico neoliberal (Torres, 2009), a la economía urbana y al mercado del suelo (Abramo, 2008). Sin embargo, el caso de estudio de la ciudad colombiana de Yopal evidencia que la informalidad urbana tiene su causa estructural en asuntos históricos, culturales y simbólicos asociados con los conflictos agrarios y con la inequitativa distribución de la tierra, los cuales han sido la base del conflicto armado en Colombia (LeGrand, 1988). Este artículo proponeampliar la discusión sobre la informalidad urbana en Colombia a partir de la comprensión de los imaginarios sociales que explican el uso y distribución de la propiedad y de la informalidad urbana, y los imaginarios que sustentan las acciones institucionales y de los actores sociales para actuar física y simbólicamente sobre los espacios que habitan o controlan.

Sedi
ment accumulation and alternately submerged caused by water conservancy engineering pose challenges to ecological restoration in riparian zones. In this study, a hybrid model coupling convolutional neural network (CNN), long short-term memory network (LSTM), and batch normalization (BN) techniques was employed to predict the concentrations of physiological indicators (soluble sugars (SS), soluble proteins (SP), malondialdehyde (MDA), and chlorophyll-a (Chla) content) in five herbaceous plants under varying water-sediment conditions. The findings indicated that the CNN-LSTM model outperformed the LSTM model in forecasting the overall trend and fluctuations of the data, particularly with reduced bias in predicting extreme values. Additionally, the CNN-LSTM-BN model improved predictive capabilities for the four physiological indicators. The mean absolute error (MAE) for the true and predicted values in the verification set were 0.040, 0.039, 0.017, and 0.020, respectively. The integration of the BN layer facilitated gradient propagation of the loss function across each parameter of the model, thereby accelerating learning efficiency and enhancing training process stability. Furthermore, the CNN-LSTM-BN model successfully predicted the concentrations of SS, SP, MDA, and Chla in Paspalum wettsteinii under a 3 cm water-sediment condition, yielding MAE values of 0.308, 0.249, 0.365, and 0.169, respectively. These findings highlight the strong predictive capabilities of the CNN-LSTM-BN model. Overall, this study offers valuable insights for plant selection and maintenance strategies in riparian ecological restoration efforts within the context of water conservancy engineering.
Preparation of Silver Nanoparticles From Used X-Ray Film By Heat-Free Polyol Method
Authors:   Department of Industrial Chemistry, Faculty of Science, Chiang Mai University, Chiang Mai, 50200, Thailand, Nuntiya Apinon
Published: November 2024

Despite several studies on synthesis of silver nanoparticles, the development of a cost-effective synthesis method is still challenging. In this work, silver nanoparticles were prepared via a heat-free polyol method with used X-ray film as a silver precursor. The used X-ray film was dipped in concentrated nitric acid at room temperature using a 1:1 liquid:solid ratio to obtain silver nitrate/nitric acid media. The results obtained show that silver about 99% is achieved. The heat-free polyol method uses ethylene glycol (EG), polyvinylpyrrolidone (PVP), ammonium hydroxide and hydrogen peroxide as a reducing agent, capping agent, and reaction catalyst, respectively. Adding silver nitrate/nitric acid to the polyol cause a reaction temperature increase of up to 60 degrees Celsius. The presence of ammonium hydroxide and nitric acid in the reaction enabled easier oxidation of ethylene glycol without heating. The synthesized silver nanoparticles were investigated by Transmission Electron Microscopy (TEM). The particle size of silver nanoparticles can be varied from 10 to 50 nm by controlling experimental parameters.

T
his study investigated the upper mesophilic temperature acclimation of halophilic, hydrogen-producing bacteria from salt fields, focusing on microbial abundance changes during dark fermentation. Genomic techniques, including PCR-denaturing gradient gel electrophoresis (DGGE) and next-generation sequencing (NGS), were used to profile the microbial communities. At 48°C, Halanaerobacter lacunarum showed significant abundance, correlating with increased hydrogen yield, suggesting its role in hydrogen production. While a decrease in H. lacunarum and Halanaerobium fermentans dominance was observed at 42°C due to other bacterial species’ growth, their dominance increased notably to 45°C and 48°C. This study highlights the adaptation potential of Halanaerobium sp. and other halophilic bacteria to upper mesophilic temperatures for hydrogen production. The findings emphasize optimizing temperature and pH conditions to maximize hydrogen yield during high-salt dark fermentation.

Noise suppression and image enhancement in cold atom absorption imaging
Authors: Zheng Pengcheng , Zhang Songqian , Ma Zhu , Niu Haipo , Wu Jiatao , Huang Zerui , Han Chengyin , Lu Bo , Liu Peiliang , Lee Chaohong
Published: December 2024

The noise in absorption imaging of cold atoms significantly impacts measurement accuracy across a range of applications with ultracold atoms. It is crucial to adopt an approach that offers effective denoising capabilities without compromising the unique structure of atom clouds. Here, we introduce, to our knowledge, a novel image enhancement algorithm for cold atomic absorption imaging. The algorithm successfully suppresses background noise, enhancing image contrast significantly. Experimental results showcase that this approach can improve the image’s signal-to-noise ratio by about 10 dB and enhance the uncertainty of cold atom number measurements by approximately tenfold, preserving the spatial distribution of the atom clouds. Moreover, the method exhibits exceptional performance and robustness when confronted with fringe noise and multi-component imaging scenarios, offering high stability. Importantly, this method can perform denoising based on a single image (without the need to establish a reference library), and the optimization process is entirely automated, eliminating the need for manual parameter selection. The method is both compatible and practical, making it applicable to various cold atom absorption imaging fields.
Multiplexed biosensors based on interference of surface plasmons in multimode nanoslits
Authors: Valero Marcos , De Leon Israel , Ray Mallar , Berini Pierre
Published: December 2024

Multiplexed biosensors enable the simultaneous detection of multiple analytes within a single sample—a capability that holds significant importance in various fields, including environmental monitoring, food safety, and medical diagnostics. In medical diagnostics, detecting multiple biomarkers simultaneously is crucial for enhancing the diagnostic accuracy of conditions such as infectious diseases, cancer, and metabolic disorders. Biosensors based on surface plasmon resonance (SPR) are remarkable due to their high sensitivity compared to other technologies. However, current multiplexed SPR-based biosensors are bulky, expensive, and difficult to integrate in lab-on-a-chip configurations. Here, we propose a multiplexed biosensor as a periodic array of plasmonic biosensor unit cells, consisting of a plasmonic interferometer located on the top of the substrate, excited by a pair of grating couplers such that the surface plasmons converge to a multimode nanoslit that produces the output signal emerging through the substrate. Microfluidic channels are integrated into the structure, thereby defining the sensing regions of each interferometer. The biosensor unit cells can be monitored individually and simultaneously by imaging their output onto a camera. Absorbing shadow elements are integrated into the structure to minimize crosstalk and background light, thereby enabling excitation of the entire array by a single large monochromatic Gaussian beam. The array can be scaled lithographically, and its interrogation is scaled by increasing the size and power of the Gaussian beam and the size of the monitoring camera. We demonstrate the concept via electromagnetic simulations and predict resolutions of R

Quantum-Photonic Treatment for Nano-Dispersion
Authors: Mahmoudi Sina , Saberi Mahdi , Kaatuzian Hassan , Shalchian Majid
Published: December 2024

Nano-dispersion (N.D.) represents the precise control and manipulation of light dispersion at the quantum atomic level in atto-second time scale within nanostructures. This study investigates N.D. using Quantum Photonics (Q.P.) theory to analyze light interactions with nanomaterials, producing distinct dispersion effects. Utilizing Monte Carlo time domain modeling, we simulate photon interactions to highlight the unique properties and applications of N.D. in enhancing nanoscale optical devices. Our results demonstrate when the space-time dimensions in simulations become enough large N.D. predictions asymptote to classical Snell's law, validating Q.P. theory's efficacy. Additionally, we observe that while classical Snell's Law accurately describes light behavior at smaller angles, Q.P. theory provides more precise predictions at steeper angles, accounting for quantum interactions not considered in classical models. Nano-dispersion is estimated for a typical Orthorhombic crystal lattice. Simulation results based on Montecarlo time domain modeling and simulation, follows the experimental results always with less than 4% error.

Design of a Horizontal Chiral Thin Film Array for Optical Filter Applications in the Visible Range
Authors: Muntaser Akram , Chatterjee Monish R
Published: December 2024

In this study, we present a chiral thin film resonator array aligned horizontally and illuminated by a collimated linear, p-polarized plane wave incident normally on the array. Each thin film is analyzed via evaluating of the corresponding mode spectra emerging from multiple transitions within the thin film under variable chirality coefficients such as thin film thickness and length, and substrate placement conditions as a function of the (monochromatic) mode frequency. The spectral behavior of (2n+1) thin films overlapping at a specific vertical point is examined under uniform illumination at a single frequency within the visible range. This analysis aims to optimize the transmission of incident plane waves (resulting from the superposed transmitted waves) within the visible spectrum that may utilized to be used as an optical filter that gives high gain along with high Q (for tuned bandpass operation) and also band reject with low gain.

Authors: Cornwall Patrick , Forschner Stefan , Kassem Khaled , Ballester Manuel , Balaji Muralidhar Madabhushi , Katsaggelos Aggelos , Faccio Daniele , Willomitzer Florian
Published: December 2024

Imaging through scattering media still presents a challenge for modern optical imaging techniques. The problem becomes even worse for dynamic scattering scenes, e.g., to capture dynamic objects behind a scatterer or when the scattering medium itself is in constant movement, such as fog or living tissue. This contribution introduces a first step towards a potential solution, which builds upon our previous Synthetic Wavelength Imaging techniques. We showcase the feasibility of our approach by imaging an extended hidden object through a scatterer in single-shot.
