Investigation of the purpose, functions and tasks of proceedings in cases of administrative offenses
Authors: Ivanov Vitaliy Ivanovich 
Published: February 2024

The object of the study is the general purpose and function, as well as the tasks of the proceedings in cases of administrative offenses. The interdependence and relativity of the concepts of "purpose" and "task" of proceedings in cases of administrative offenses cause difficulties in establishing their distinctive features and mutual differentiation, and therefore the issue of defining these categories in the science of administrative law is currently debatable. For this reason, the works of prominent Russian jurists such as D. N. Bakhrah, V. V. Dorokhin, S. D. Mogilevsky, A. Y. Yakimovich, revealing the content and essence of these concepts from different sides, formed the subject of this study. The specificity of the research object was a decisive factor in determining the research methodology. In preparing the article, a set of general scientific and private scientific methods was used, including the method of system analysis, which ensured the validity of the author's judgments, suggestions and recommendations. Within the framework of a systematic analysis, directing the research process from a complex to a simpler manifestation of the object of research, the author, based on the patterns of formation of tree-like hierarchical structures, reveals the content of the above concepts in an original way, defines the general law-restoring nature of production, identifies the law enforcement stages in it, as well as the goals and special tasks of each stage. As a result of the research, the author's version of Article 24.1 of the Code of Administrative Offenses of the Russian Federation is proposed, which establishes a legal definition of the purpose of proceedings in cases of administrative offenses. Proposals for improving the current legislation indicate the applied significance of this study, while some conclusions and theoretical generalizations of the author can be used to conduct further research in this direction.
Optical Sensors Based on Hybrid DNA/Conjugated Polymer Complexes
Authors: Ho Hoang‐Anh , Béra‐Abérem Maïté , Leclerc Mario 
Published: November 2004

AbstractSingle‐stranded DNA (ss‐DNA) can specifically bind to various targets, including a complementary ss‐DNA, ions, proteins, drugs, and so forth. When binding takes place, the oligonucleotide probe often undergoes a conformational transition. This conformational change of the negatively charged ss‐DNA can be detected by using a water‐soluble, cationic polythiophene derivative, which transduces the complex formation into an optical (colorimetric or fluorometric) signal without any labeling of the probe or the target. This simple and rapid methodology has enabled the specific and sensitive detection of nucleic acids and human thrombin. This new biophotonic tool can easily be applied to the detection of various other biomolecules and is also useful in the high‐throughput screening of new drugs.

Published: November 2004

AbstractA photochromic polymer film containing three different diarylethene derivatives, that is, 1,2‐bis(3,5‐dimethyl‐2‐thienyl)perfluorocyclopentene (1), 1,2‐bis(2,5‐dimethyl‐3‐thienyl)perfluorocyclopentene (2), and 1,2‐bis(2‐methyl‐5‐phenyl‐3‐thienyl)perfluorocyclopentene (3) was prepared. Upon UV irradiation, the three derivatives changed to their closed‐ring isomers having different colors, yellow, red, and blue. They showed different spectra not only in UV/Vis region but also in the IR spectral region. Upon irradiation with visible light of appropriate wavelengths, each closed‐ring isomer was selectively bleached, and three bits eight states recording was performed. The eight states could be read out nondestructively by using IR light of appropriate wavenumbers.
Coordination of Iron(III) Cations to β‐Keto Esters as Studied by Electrospray Mass Spectrometry: Implications for Iron‐Catalyzed Michael Addition Reactions
Authors: Trage Claudia , Schröder Detlef , Schwarz Helmut 
Published: November 2004

AbstractSolutions of FeIII salts and β‐keto esters have been investigated by means of electrospray ionization mass spectrometry. The complexes formed in such solutions have been considered previously as active intermediates in FeIII‐catalyzed Michael additions. By using different FeIII salts with a set of β‐keto esters, cation and anion mass spectra were analyzed and the effects of ester concentration, the role of the counterion, and the structure of the ester employed are discussed. Depending on the basicity of the ester, an increase of its concentration may lead to a decrease in the concentration of iron complexes observed in the mass spectra. Counterions with strong binding affinities to iron are found to capture the metal as ferrates, thereby removing the metal from the catalytic cycle.
Hierarchical Self‐Assembly of a Bow‐Shaped Molecule Bearing Self‐Complementary Hydrogen Bonding Sites into Extended Supramolecular Assemblies
Authors: Ikeda Masato , Nobori Tadahito , Schmutz Marc , Lehn Jean‐Marie 
Published: November 2004

AbstractThe bow‐shaped molecule 1 bearing a self‐complementary DAAD–ADDA (D=donor A=acceptor) hydrogen‐bonding array generates, in hydrocarbon solvents, highly ordered supramolecular sheet aggregates that subsequently give rise to gels by formation of an entangled network. The process of hierarchical self‐assembly of compound 1 was investigated by the concentration and temperature dependence of UV‐visible and 1H NMR spectra, fluorescence spectra, and electron microscopy data. The temperature dependence of the UV‐visible spectra indicates a highly cooperative process for the self‐assembly of compound 1 in decaline. The electron micrograph of the decaline solution of compound 1 (1.0 mM) revealed supramolecular sheet aggregates forming an entangled network. The selected area electronic diffraction patterns of the supramolecular sheet aggregates were typical for single crystals, indicative of a highly ordered assembly. The results exemplify the generation, by hierarchical self‐assembly, of highly organized supramolecular materials presenting novel collective properties at each level of organization.

Visualization of correlation‐based environmental data
Authors: Dzemyda Gintautas 
Published: November 2004

AbstractA method for the visualization of environmental data via the analysis of correlations has been proposed. As an example, the data in correlation matrices of environmental parameters that describe air pollution in Vilnius city (10 parameters) as well as the development of coastal dunes and their vegetation in Finland (16 parameters) are visualized. These applied problems are very urgent because of their ecological nature: a visual presentation of data stored in the correlation matrices makes it possible for ecologists to discover additional knowledge hidden in the matrices and to make proper decisions. The method consists of two stages: building of a system of vectors based on the correlation matrix and its visualization. Sammon's mapping and the self‐organizing map (two its realizations having different features for visualization) were applied in the visualization. The advantage of the method lies in the possibility to restore the system of multidimensional vectors describing variables from the correlation matrix—one vector for one variable.

Hierarchies inφ‐spaces and applications
Authors: Selivanov Victor L. 
Published: November 2004

AbstractWe establish some results on the Borel and difference hierarchies inφ‐spaces. Such spaces are the topological counterpart of the algebraic directed‐complete partial orderings. E.g., we prove analogs of the Hausdorff Theorem relating the difference and Borel hierarchies and of the Lavrentyev Theorem on the non‐collapse of the difference hierarchy. Some of our results generalize results of A. Tang for the spacePω. We also sketch some older applications of these hierarchies and present a new application to the question of characterizing theω‐ary Boolean operations generating a given level of the Wadge hierarchy from the open sets.

A note on a subvariety of linear tense algebras
Authors: Zander Marta A. 
Published: November 2004

AbstractIn [1], Bull gave completeness proofs for three axiom systems with respect to tense logic with time linear and rational, real and integral. The associated varieties, Dens, Cont and Disc, are generated by algebras with frames {ℚ, <, >}, {ℝ, <, >} and {ℤ, <, >}, respectively. In this paper we consider the subvariety 𝒱 generated by the finite members of Disc. We prove that V is locally finite and we determine its lattice of subvarieties. We also prove that 𝒱 = Disc ∩ Dens = Disc ∩ Cont. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Current–voltage curve translation by bilinear interpolation
Authors: Marion B. , Rummel S. , Anderberg A. 
Published: November 2004

AbstractBy means of bilinear interpolation and four reference current–voltage (I–V) curves, anI–Vcurve of a photovoltaic (PV) module is translated to desired conditions of irradiance and PV module temperature. The four referenceI–Vcurves are measured at two irradiance and two PV module temperature levels and contain all the essential PV module characteristic information for performing the bilinear interpolation. The interpolation is performed first with respect to open‐circuit voltage to account for PV module temperature, and second with respect to short‐circuit current to account for irradiance. The translation results over a wide range of irradiances and PV module temperatures agree closely with measured values for a group of PV modules representing seven different technologies. Root‐mean‐square errors were 1·5% or less for theI–Vcurve parameters of maximum power, voltage at maximum power, current at maximum power, short‐circuit current, and open‐circuit voltage. The translation is applicable for determining the performance of a PV module for a specified test condition, or for PV system performance modeling. Copyright © 2004 John Wiley & Sons, Ltd.

Authors: Gao Xin , Mathieu Hans Jörg , Schawaller Manfred 
Published: November 2004

AbstractA polystyrene biosensing chip to be used as a medical diagnostic tool has been developed. Its surface functionalization is optimized to bind the bioanalytes with high efficiency. Coatings of allyldextran monolayers were carried out on polystyrene chips activated with γ‐irradiation. The effect of the concentration of allyldextran solution on the coating efficiency was studied by surface‐sensitive x‐ray photoelectron spectroscopy (XPS) and contact‐angle measurements. In a second step, sodium periodate chemistry was applied to functionalize the dextran layer, followed by coupling with streptavidin or neutravidin. Copyright © 2004 John Wiley & Sons, Ltd.
A framework for efficient resource management in IEEE 802.11 WLANs
Authors: Zhang Liqiang , Zeadally Sherali 
Published: November 2004

AbstractCurrently deployed IEEE 802.11 WLANs work mostly with distributed coordination function (DCF) mode at the media access control (MAC) layer, which does not provide quality of service (QoS) support. The upcoming IEEE standard 802.11e achieves service differentiation by assigning different channel access parameters (CAPs) to different traffic classes at the MAC layer. However, such relative differentiation does not yield QoS guarantee. In practice, appropriately selecting CAPs a priori is difficult. Time‐varying traffic loads also make the use of fixed CAPs, inefficient for both QoS support and channel utilization. In this work, we propose a novel architecture called HARMONICA, in which the access point (AP) dynamically selects the best CAPs for each traffic class to optimally match their QoS requirements. We present and discuss a simple admission control (AC) mechanism used by HARMONICA to avoid congestion. Our simulation results demonstrate that under an interference‐free environment, HARMONICA can guarantee the QoS for all traffic classes while simultaneously achieving quasi‐optimal channel utilization.

Performance evaluation of an adaptive backoff scheme for WLAN
Authors: Pang Qixiang , Liew Soung C. , Lee Jack Y. B. , Leung Victor C. M. 
Published: November 2004

AbstractIn this paper, a simple self‐adaptive contention window adjustment algorithm for 802.11 wireless local area networks (WLAN) is proposed and analyzed. Numerical results show that the new algorithm outperforms the standard 802.11 window adjustment algorithm. Compared with the standard and previously proposed enhancement algorithms, a salient feature of our algorithm is that it performs well in both heavy and light contention cases regardless of the packet sizes and physical versions. Moreover, the adaptive window adjustment algorithm is simpler than previously proposed schemes in that no live measurement of the WLAN traffic activity is needed.

Adaptive polling MAC schemes for IEEE 802.11 wireless LANs supporting voice‐over‐IP (VoIP) services
Authors: Kim Young‐Jae , Suh Young‐Joo 
Published: November 2004

AbstractThe IEEE 802.11 standard specifies the point coordination function (PCF) in the media access control (MAC) sublayer for the transfer of real‐time traffic, such as voice. The transfer of real‐time traffic over wireless LANs is rapidly gaining acceptance, but little work has been done concerning the efficient use of IEEE 802.11 PCF mode to support voice‐over‐IP (VoIP) services. In this paper, we propose adaptive polling MAC schemes for IEEE 802.11 MAC. The proposed schemes achieve bandwidth efficiency by reducing the number of polls required for the uplink voice packet transmissions using a talkspurt detection algorithm. We analyze the applicability of the proposed schemes to IEEE 802.11 WLANs and compare them with other related works. Copyright © 2004 John Wiley & Sons, Ltd.
