description: The microstructure investigated in this study was inspired by the anisotropic microornamentation of scales from the ventral body side of the California King Snake (Lampropeltis getula californiae). Frictional properties of snake-inspired microstructured polymer surface (SIMPS) made of epoxy resin were characterised in contact with a smooth glass ball by a microtribometer in two perpendicular directions. The SIMPS exhibited a considerable frictional anisotropy: Frictional coefficients measured along the microstructure were about 33% lower than those measured in the opposite direction. Frictional coefficients were compared to those obtained on other types of surface microstructure: (i) smooth ones, (ii) rough ones, and (iii) ones with periodic groove-like microstructures of different dimensions. The results demonstrate the existence of a common pattern of interaction between two general effects that influence friction: (1) molecular interaction depending on real contact area and (2) the mechanical interlocking of both contacting surfaces. The strongest reduction of the frictional coefficient, compared to the smooth reference surface, was observed at a medium range of surface structure dimensions suggesting a trade-offbetween these two effects.

description: The three-body Schrödinger equation of the H$_2^+$ hydrogen molecular ion with Coulomb potentials is solved in perimetric coordinates using the Lagrange-mesh method. The Lagrange-mesh method is an approximate variational calculation with variational accuracy and the simplicity of a calculation on a mesh. Energies and wave functions of up to four of the lowest vibrational bound or quasibound states for total orbital momenta from 0 to 40 are calculated. The obtained energies have an accuracy varying from about 13 digits for the lowest vibrational state to at least 9 digits for the third vibrational excited state. With the corresponding wave functions, a simple calculation using the associated Gauss quadrature provides accurate quadrupole transition probabilities per time unit between those states over the whole rotational bands. Extensive results are presented with six significant figures.

description: Heat transfer can differ distinctly at the nanoscale from that at the macroscale. Recent advancement in computational and experimental techniques has enabled a large number of interesting observations and understanding of heat transfer processes at the nanoscale. In this review, we will first discuss recent advances in computational and experimental methods used in nanoscale thermal transport studies, followed by reviews of novel thermal transport phenomena at the nanoscale observed in both computational and experimental studies, and discussion on current understanding of these novel phenomena. Our perspectives on challenges and opportunities on computational and experimental methods are also presented.

description: Intended exposure to gold and silver nanoparticles has increased exponentially over the last decade and will continue to rise due to their use in biomedical applications. In particular, reprotoxicological aspects of these particles still need to be addressed so that the potential impacts of this development on human health can be reliably estimated. Therefore, in this study the toxicity of gold and silver nanoparticles on mammalian preimplantation development was assessed by injecting nanoparticles into one blastomere of murine 2 cell-embryos, while the sister blastomere served as an internal control. After treatment, embryos were cultured and embryo development up to the blastocyst stage was assessed. Development rates did not differ between microinjected and control groups (gold nanoparticles: 67.3%, silver nanoparticles: 61.5%, sham: 66.2%, handling control: 79.4%). Real-time PCR analysis of six developmentally important genes (BAX, BCL2L2, TP53, OCT4, NANOG, DNMT3A) did not reveal an influence on gene expression in blastocysts. Contrary to silver nanoparticles, exposure to comparable Ag+-ion concentrations resulted in an immediate arrest of embryo development. In conclusion, the results do not indicate any detrimental effect of colloidal gold or silver nanoparticles on the development of murine embryos.

description: В статье анализируются тенденции развития государственно-политической жизни Туниса в XIX в. В истории развития Туниса это время ознаменовано значительными переменами, связанными с процессами модернизации системы государственного управления и законодательства. Автором были поставлены задачи выяснения, каким образом Тунис оказался французской колонией, определения стратегии развития государства в указанное время. Внимание уделяется содержательной составляющей проведения реформ XIX в., как со стороны правящей тунисской власти, так и во время установления протектората Франции. Несмотря на то, что Тунис был наиболее верстернизированной страной арабского мира, узаконения шариата и традиции исламской общины имели здесь глубокие корни. Это задавало тренд в сторону отторжения государственно-правовых реформ, проводимых правящей монархией Хусейнидов, в духе наполеоновской эпохи. Реформаторский потенциал имел ограничения и внешнего порядка, связанные с колониальными интересами Франции. Анализ сложившейся исторической ситуации показывает стратегию модернизации традиционного тунисского общества и государства, заключенную в попытках совместить нормы ислама с европейскими ценностями и гражданскими институтами, предпринимаемыми местной монархией и позже Францией.

description: In this paper, we study the performance of blind adaptive beamforming algorithms for smart antennas in realistic environments. A constrained constant modulus (CCM) design criterion is described and used for deriving a recursive least squares (RLS) type optimization algorithm. Furthermore, two kinds of scenarios are considered in the paper for analyzing its performance. Simulations are performed to compare the performance of the proposed method to other well-known methods for blind adaptive beamforming. Results indicate that the proposed method has a significant faster convergence rate, better robustness to changeable environments and better tracking capability.

description: В статье затрагивается проблема влияния процессов глобализации на формирование и развитие национального права, на государственный суверенитет, в целом, и на реализацию принципа государственного суверенитета в правовом регулировании общественных отношениях на уровне национальных государств. Процессы глобализации в праве рассматриваются в рамках исторического подхода, как следствие развития международно-правового регулирования отношений между государствами, формирования понимания правового статуса личности, а также раскрывается негативное влияние на процесс развития национального права в связи с тем, что международные стандарты правового регулирования учитывают только традиции права государств условного Запада при игнорировании традиционных ценностей права иных государств. Устанавливается, что борьба с глобализационными процессами в области права возможна только на основе развития национального права с учетом принципов и норм международно-правового характера.

description: In the present work, we apply the one-boson-exchange potential (OBEP) model to investigate the possibility of Y(2175) and $η(2225)$ as bound states of $Λ\barΛ(^3S_1)$ and $Λ\barΛ(^1S_0)$ respectively. We consider the effective potential from the pseudoscalar $η$-exchange and $η^{'}$-exchange, the scalar $σ$-exchange, and the vector $ω$-exchange and $ϕ$-exchange. The $η$ and $η^{'}$ meson exchange potential is repulsive force for the state $^1S_0$ and attractive for $^3S_1$. The results depend very sensitively on the cutoff parameter of the $ω$-exchange ($Λ_ω$) and least sensitively on that of the $ϕ$-exchange ($Λ_ϕ$). Our result suggests the possible interpretation of Y(2175) and $η(2225)$ as the bound states of $Λ\barΛ(^3S_1)$ and $Λ\barΛ(^1S_0)$ respectively.

В первое десятилетие Советской власти в традиционном ингушском обществе происходили сложные и серьезные перемены. В рамках борьбы за ликвидацию «национальных окраин» и создание национальных автономий Советская власть начала осуществлять политику «коренизации». Самое серьезное внимание уделялось вопросу «коренизации» и в Ингушской автономной области. «Коренизация» предполагала подготовку кадров из числа ингушей и вовлечение их в производство. Цель данной статьи выявить особенности проведение политики «коренизации» в Ингушетии.

description: Two-photon polymerization of photosensitive materials has emerged as a very promising technique for the fabrication of photonic crystals and devices. We present our investigations into the structuring by two-photon polymerization of a new class of photosensitive sol-gel composites exhibiting ultra-low shrinkage. We particularly focus on two composites, the first containing a zirconium alkoxide and the second a nonlinear optical chromophore. The three-dimensional photonic crystal structures fabricated using these materials demonstrate high resolution and clear bandstops in the near IR region.

description: Universal quantum computers promise a dramatic speed-up over classical computers but a full-size realization remains challenging. However, intermediate quantum computational models have been proposed that are not universal, but can solve problems that are strongly believed to be classically hard. Aaronson and Arkhipov have shown that interference of single photons in random optical networks can solve the hard problem of sampling the bosonic output distribution which is directly connected to computing matrix permanents. Remarkably, this computation does not require measurement-based interactions or adaptive feed-forward techniques. Here we demonstrate this model of computation using high--quality laser--written integrated quantum networks that were designed to implement random unitary matrix transformations. We experimentally characterize the integrated devices using an in--situ reconstruction method and observe three-photon interference that leads to the boson-sampling output distribution. Our results set a benchmark for quantum computers, that hold the potential of outperforming conventional ones using only a few dozen photons and linear-optical elements.
Elliptic Flow of Protons and Antiprotons in Au+Au Collisions at $\sqrt{s_{NN}}$ = 7.7--62.4 GeV within Alternative Scenarios of Three-Fluid Dynamics

description: Analysis of elliptic flow of protons and antiprotons in Au+Au collisions is performed in a wide range of incident energies $\sqrt{s_{NN}}$ = 7.7--62.4 GeV. Simulations has been done within the three-fluid model employing a purely hadronic equation of state (EoS) and two versions of the EoS involving deconfinement transition: an EoS with the first-order phase transition and that with a smooth crossover transition. It is found that the proton data are reproduced approximately to the same extent within all of the scenarios, including the hadronic one, while the deconfinement scenarios look certainly preferable for the antiproton elliptic flow. The fact that difference between elliptic flows of protons and antiprotons decreases with the incident energy rise is a consequence of reducing baryon stopping rather than an onset of deconfinement.

description: In general, professionals still ignore scientific evidence in place of expert opinions in most of their decision-making. For this reason, it is still common to see the adoption of new software technologies in the field without any scientific basis or well-grounded criteria, but on the opinions of experts. Experimental Software Engineering is of paramount importance to provide the foundations to understand the limits and applicability of software technologies. The need to better observe and understand the practice of Software Engineering leads us to look for alternative experimental approaches to support our studies. Different research strategies can be used to explore different Software Engineering practices. Action Research can be seen as one alternative to intensify the conducting of important experimental studies with results of great value while investigating the Software Engineering practices in depth. In this paper, a discussion on the use of Action Research in Software Engineering is presented. Aiming at better explaining the application of Action Research, an experimental study (in vivo) on the investigation of the subjective decisions of software developers, concerned with the refactoring of source code to improve source code quality in a distributed software development context is depicted. In addition, some guidance on how to accomplish an Action Research study in Software Engineering supplement the discussions.

description: Указ Президента РФ «О проведении в Российской Федерации Года педагога и наставника» в 2023 г. был принят в целях признания особого статуса педагогических работников и начало его действия совпало с юбилеем А.С. Макаренко. Это имя отмечено словами президента на старте года педагога, но в практической жизни у нас педагога не отличают от андрагога и только недавно был установлен день работника высшей школы. Для А.С. Макаренко главным в воспитании было предъявление требований нормального поступка воспитанникам, но в категорическом требовании к воспитаннику уже тогда был риск. Сегодня конфликты между педагогами и школьниками связаны с тем, что в школах с 90 гг. искореняли воспитательную функцию, а общество утратило государственную идеологию. Поскольку вопрос заключается либо в предъявлении наших гражданских требований, либо в отказе от них, а именно они формируются в ходе Специальной военной операции, острой стала задача воспитания российской политической элиты и молодого поколения. Рискованная педагогика трансформируется в философию категорического требования к воспитуемому, но на деле это обращение не к воспитуемому, а к коллективу. Советская педагогика открыла закон параллельного действия, когда в роли воспитателя выступает коллектив учащихся, а каждый воспитанник, участвуя в деятельности коллектива, сам воспитывается. Именно это не желали видеть чиновники соцвоса и не принимали педологи прошлого столетия.

description: We present fiber-coupled dielectric-loaded plasmonic waveguides for 1.55 m telecom wavelength fabricated by two-photon polymerization and nanoimprint lithography. The waveguide structures include 100- m-long plasmonic waveguides connected on both ends to tapered dielectric waveguides used for end-fire coupling with optical fibers. The excitation of plasmonic waveguides is verified via polarization-resolved measurements of the overall transmission, demonstrating thereby that this technology is suitable in principle for the integration of plasmonic components into fiberoptics. Loss mechanisms are investigated and improvements suggested to reduce transmission losses and consequently increase the viability of practical application.

description: Zr-Si organic-inorganic scaffolds fabricated by a two-photon polymerization technique were used for the primary culture of mouse embryonic neural cells. We observed that dissociated hippocampal cells adhere to the scaffolds, produce neurites, elongate and differentiate into adult neurons. Neuronal outgrowth and synaptogenesis were confirmed by immunohistochemical staining with antibodies against βIII-Tubulin and synaptophysin. The formation of a functional neural network was assessed by the measurement of spontaneous activity using Ca2+ imaging of dissociated hippocampal cultures grown on Zr-Si scaffolds. The results of this study suggest that two-photon-induced polymerization of organic-inorganic hybrid biomaterials provides a robust model for 3D neuronal tissue engineering studies.

description: The double-lined spectroscopic binary HD 104237 (DX Cha) is part of a complex system of some half-dozen nearby young stars. We report a significant change from an orbit for the SB2 system derived from 1999-2000 observations. We obtain abundances from the primary and secondary spectra. The abundance analysis uses both detailed spectral synthesis and determinations based on equivalent widths of weak absorption lines with W(lambda) typically < 25 mA. Abundances are derived for 25 elements in the primary, and 17 elements in the secondary. Apart from lithium and zirconium, abundances do not depart significantly from solar. Lithium may be marginally enhanced with respect to the meteoritic value in the primary. It somewhat depleted in the secondary. The emission-line spectrum is typical of Herbig Ae stars. We compare and contrast the spectra of the HD 104237 primary and two other Herbig Ae stars with low v.sin(i), HD 101412 and HD 190073.

description: The dispersion relation and propagation of surface plasmons polaritons (SPPs) on nanoporous gold films is experimentally investigated and an increasing red shift of the SPPs is observed with rising porosity. This is caused by a less negative effective dielectric constant of the nanoporous metal films and is predicted by classical Bruggeman or specific two dimensional Maxwell-Garnett effective medium models. The dispersion relation data is supported with leakage radiation microscopy enabling the determination of the propagation length and losses of surface plasmons on these nanoporous films. These results demonstrate how the control of the nanoporosity of metal layers leads to designer plasmons in the visible and near infrared allowing the tuning of the SPP dispersion to match the requirements of certain applications.

description: There are different algorithms for vocal fold pathology diagnosis. These algorithms usually have three stages which are Feature Extraction, Feature Reduction and Classification. While the third stage implies a choice of a variety of machine learning methods, the first and second stages play a critical role in performance and accuracy of the classification system. In this paper we present initial study of feature extraction and feature reduction in the task of vocal fold pathology diagnosis. A new type of feature vector, based on wavelet packet decomposition and Mel-Frequency-Cepstral-Coefficients (MFCCs), is proposed. Also Principal Component Analysis (PCA) is used for feature reduction. An Artificial Neural Network is used as a classifier for evaluating the performance of our proposed method.

description: Активные процессы реформирования конституционно-правовых институтов публичной власти, во многом спровоцированные геополитическими процессами в современном мире, требуют новейшего доктринального осмысления концепции конституционных прав и свобод человека и гражданина в контексте обеспечения повышения уровня охраны института государственного суверенитета, как на внутринациональном , так и на наднациональном уровне правового регулирования. При этом, очевидными представляются не только необходимость неуклонного следования общеправовому конституционно гарантированному принципу законности в целом, но и признание целесообразности актуализации в современном публичном управлении принципа баланса политических сил и интересов личности в современной России, провозглашенной правовым и демократическим государством. Эпоха конституционных реформ, свойственная для современного состояния российской государственности неминуемо будет сопровождаться изменениями доктринальных представлений о природе, пределах суверенитета, а также расширением перечня видов суверенитета, включающего народный, национальный, государственный, а также провозглашенный недавно образовательный суверенитет. На фоне трансформации доктринальных представлений отечественных конституционалистов о сущности и содержании института государственного суверенитета логичным представляется осмысление его генезиса с целью репродуктивного анализа модели публичной власти в целом.

description: Nowadays, Ion Beam Sputter (IBS) processes are very well optimized on an empirical basis. To achieve further progresses, a modification of the IBS process by guiding the coating material using an axial magnetic field and an additional electrical field has been studied. The electro-magnetic (EM) field leads to a significant change in plasma properties and deposition rate distributions, whereas an increase in deposition rate along the centerline of the axial EM field around 150% was observed. These fundamental studies on the prototype are the basis for the development of an applicable and workable design of a separation device.

description: We consider the light-quark axial-vector current correlator in the framework of thermal QCD sum rules to: (a) find a relation between chiral-symmetry restoration and deconfinement, and (b) determine the temperature behaviour of the $a_1(1260)$ width and coupling. Our results show that deconfinement takes place at a slightly lower temperature than chiral-symmetry restoration.This difference is not significant given the accuracy of the method. The behaviour of the $a_1(1260)$ parameters is consistent with quark-gluon deconfinement, since the width grows and the coupling decreases with increasing temperature.

description: Differenzierungstheoretisches Gestaltungsdenken gilt entweder als veraltet oder wird allenfalls zur Begründung für scheiternde Steuerung oder unintendierte Nebenfolgen herangezogen; Steuerungsansinnen prallen auf systemischen Eigensinn. Das Buch »Die Korrektur der Gesellschaft« beschäftigt sich wesentlich mit der Bearbeitung der Folgen funktionaler Differenzierung. Vor der Problembearbeitung auch nur eines Systems fällt zunächst die Umwandlung von Irritationen in je spezifische Informationen an. Legt man über diese systemtheoretische Vorlage hinaus multiple Differenzierung zugrunde, potenzieren sich die Probleme: Die Bearbeitung muss noch weit mehr Filter passieren als bloß die der Funktionssysteme. Und dennoch werden in der Gegenwartsgesellschaft all diese Zusatzschwierigkeiten reflexiv gewendet: Übersetzungsschwellen sind kein gesellschaftstheoretisches Spezialwissen, sondern finden sich ihrerseits übersetzt in buchstäblich umsichtigen Praxen der Gesellschaftskorrektur, wie dies im zu besprechenden Buch am Beispiel investigativ-journalistischer Organisationen illustriert wird. Anderen, nicht unmittelbar erreichbaren Verstehenskontexten ein Ignorieren zu erschweren, ist der Kern des Konzepts der Irritationsgestaltung. Ebendies fordert wiederum die Differenzierungstheorie auf, sich nicht nur auf die Verarbeitungsseite zu beziehen und als Responsivität anzunehmen, Gesellschaftsbereiche kämen ihrerseits auf Großprobleme zu. Stattdessen gilt es, die Anregungsseite in den Blick zu nehmen, nicht obwohl, sondern weil niemand mit bruchlosem Durchgriff rechnet. Dazu gehört auch das differenzierungstheoretische Einstellen auf Bedingungen der Digitalisierung (Lassen sich Übersetzungsschwellen technisieren?) und der Globalisierung (variierende Ordnungsmuster).

description: The Gond community is considered to be one of the most ancient tribes of India with a continuing history of several thousand years. They are also known for their largely isolated history which they have retained through the millennia. Several of their intellectual traditions therefore are a record of parallel aspects of human intellectual growth, and still preserve their original flavour and have not been homogenised by the later traditions of India. In view of this, the Gonds provide a special window to the different currents that constitute contemporary India. In the present study, we summarise their mythology, genetics and script. We then investigate their astronomical traditions and try to understand this community through a survey of 15 Gond villages spread over Maharashtra, Andhra Pradesh and Madhya Pradesh. We show that they have a distinctly different view of the sky from the conventional astronomical ideas encountered elsewhere in India, which is both interesting and informative. We briefly comment on other aspects of their life as culled from our encounters with different members of the Gond community.

description: Eine Replik auf Kommentare zu einem Buch namens »Die Korrektur der Gesellschaft« lädt zu einem inflationären Gebrauch des Korrekturbegriffs ein. Ein solcher soll hier unbedingt vermieden werden. Die vielfältigen Anregungen aus allen Kommentaren weiß ich sehr zu schätzen, schließlich wird das besprochene Buch selbst nicht müde zu betonen, dass es sich lohnt, sich für die Anregungsseite zu interessieren und es nicht bei der Beobachtung der Reaktions- oder Verarbeitungsseite zu belassen, wie es die differenzierungstheoretische Regel ist. Ich bedanke mich herzlich für die Möglichkeit eines derart intensiven Austauschs. Ein wesentlicher Ausgangspunkt des Buchs, so viel Rückschau sei gestattet, war die Annahme, dass es einerseits noch andere als funktionale Differenzierung und andere zu berücksichtigende Einheiten als Funktionssysteme, Organisationen und Interaktionen gibt, es sich andererseits aber trotzdem lohnt, sich für die Anregungsseite (zu Korrekturen) zu interessieren. Nie zuvor waren mehr Korrekturschwierigkeiten benennbar, nie zuvor gleichermaßen elaborierte Praxen ihrer Bearbeitung beobachtbar.

description: В работе рассматривается правовая природа принципов осуществления корпоративных прав. Раскрываются самостоятельные принципы корпоративных прав. Анализируется современное гражданское и корпоративное законодательство. Раскрывается роль принципов в правоприменительной практике. На сегодняшний день корпоративное законодательство несовершенно, не предусматривает эффективной правовой защиты нарушенных прав и интересов участников корпоративных правоотношений. Важная роль в развитии принципов корпоративных прав отводится изучению сущностного понимания принципов права. Можно уже с уверенность констатировать о существовании самостоятельных принципах корпоративного права, к которым отнесем: принцип демократии, добросовестности, обеспечения стабильности гражданско-правового договора и др. Отмеченные принципы напрямую относятся к регулированию корпоративных отношений в корпорации, они направлены на создание доверия в отношениях, возникающих в связи с управлением корпоративной организацией. Осуществление корпоративных прав в соответствии с назваными принципами является существенной особенностью их реализации. На сегодняшний день прослеживается тенденция постепенного развития и совершенствования корпоративного законодательства. Однако некоторые вопросы оставлены за рамками правового регулирования, которые также нуждаются в правовой разработке, прежде всего для эффективной и своевременной правовой защиты нарушенных прав и интересов самих участников корпораций. Существующая проблематика создает ситуацию правовой неопределенности в данной сфере. Определенные проблемы связаны с нарушением имущественных и неимущественных прав акционеров требуют пристального внимания и регулирования. Не менее важными вопросами являются и те, которые напрямую связаны с управлением корпоративной организацией, а также с осуществлением корпоративных прав и их защиты.

description: Quantum networks are a rapidly developing field of quantum information processing that have the potential to enable long-range entanglement between future quantum computers as well as the implementation of secure communication through quantum key distribution. Two key components of such networks are quantum memories to store entangled photon pairs for use in the quantum repeater protocol and quantum light-matter interfaces to efficiently interconvert between stationary qubits and flying qubits in the form of photons. Rare-earth ion-doped crystals are a promising solid-state platform that show promise for both of these applications due to their long optical and spin coherence times. Due to their relatively weak optical transitions, rare-earth ions have been coupled with nanophotonic resonators to enhance their transition strengths, with past work in the Faraon group utilizing focused ion beam milled  photonic crystal resonators with 45-degree angled couplers to couple light in and out. Such resonators have the disadvantage of requiring manual alignment to fabricate, and the couplers are also relatively inefficient which limits the performance of such devices. It is therefore desirable to move towards silicon photonics, where mature techniques such as electron-beam lithography can allow for scalable fabrication of nanophotonic cavities together with high coupling efficiencies.

In this thesis, we demonstrate significant progress towards the usage of acid-etched tapered optical fibers as an efficient interface for coupling light into tapered silicon nanophotonic waveguides. We show comprehensive simulations of the taper geometries required to achieve adiabatic coupling with theoretical efficiencies of more than 99%, and design a silicon photonic crystal mirror to be used in the measurement of the fiber-waveguide coupling efficiency. We then optimize the hydrofluoric acid fiber etching process and demonstrate the ability to make tapered fibers which are 200 microns long with a taper half-angle of 2 degrees and a tip diameter of 50 nm. Using these tapered fibers to couple light into tapered silicon waveguides fabricated using electron-beam lithography shows a moderately high coupling efficiency of 11.4% with the potential for improvement. This method of tapered fiber coupling shows promise to be integrated into silicon nanophotonic resonators on rare-earth ion doped crystals and allow for highly efficient quantum memories and quantum light-matter interfaces in the solid-state.

description: Die Aufmerksamkeitsökonomie von Gegenwartsgesellschaften, so lässt sich eine der Prämissen von Marc Mölders’ zwar vergleichsweise schmaler aber umso ambitionierterer und, um es gleich zu sagen: unbedingt lesenswerter Studie zusammenfassen, lässt die Generierung von »Publizität« zu der entscheidenden Stellschraube für gezielte Einflussnahmen auf den Wandel gesellschaftlicher Strukturen werden (89 ff.1). Zwar geht diese Entwicklung mit einem erhöhten Aufkommen öffentlich vernehmbarer kritischer Interventionen einher, sie entzieht ihnen aber zugleich systematisch notwendige Resonanz und reduziert damit die Wahrscheinlichkeit ihres Erfolges. Im Medium von Publizität (101 ff.), so wiederum die Hauptthese der Arbeit, basiere die Chance zum Anstoß von Veränderungen daher darauf, die Irritation von Funktionssystemen über Systemgrenzen hinweg so zu gestalten, dass ihre Ignorierbarkeit in allen drei Sinndimensionen der Systemtheorie minimiert, der Aufmerksamkeits- und Irritationseffekt also zu relativ dauerhaften, insofern stabilisierten Zumutungen gesteigert und so ein entsprechender Anpassungsdruck aufgebaut wird.

description: In the past few years, like other fields, rapid expansion of digitization and globalization has influenced the medical field as well. For progress of diagnostic results most of the reputed hospitals and diagnostic centres all over the world have started exchanging medical information. In this proposed method, the calculated diagnostic parametric values of the original Electrooculography (EOG) signal are embedded as a watermark by using Difference Expansion (DE) algorithm based reversible watermarking technique. The extracted watermark provides the required parametric values at the recipient end without any post computation of the recovered EOG signal. By computing the parametric values from the recovered signal, the integrity of the extracted watermark can be validated. The time domain features of EOG signal are calculated for the generation of watermark. In the current work, various features are studied and two major features related to blink frequency are used to generate the watermark. The high Signal to Noise Ratio (SNR) and the Bit Error Rate (BER) claim the robustness of the proposed method.
