Does Public Administration Higher Education in CEECs Reflect Demands Created by NPM Reforms?
The first part of the paper summarizes NPM approaches in public administration reforms in the countries of Central and Eastern Europe (CEECs), and focuses particularly on contracting of public services delivery, outsourcing of supportive services in public organizations and Program (performance) budgeting and performance evaluation and financing. The problems discussed in the first part open a discussion on public management education of civil servants in CEECs with which deals the second part of the paper. The data available clearly indicate that the contents and quality of public management higher education in the three selected countries - Slovakia, Czech Republic and Poland - do not meet the current needs of a modern state.

Positive stable realizations with system Metzler matricesConditions for the existence of positive stable realizations with system Metzler matrices for linear continuous-time systems are established. A procedure for finding a positive stable realization with system Metzler matrix based on similarity transformation of proper transfer matrices is proposed and demonstrated on numerical examples. It is shown that if the poles of stable transfer matrix are real then the classical Gilbert method can be used to find the positive stable realization.

Predictors of SOZ localization, subsequent surgical intervention, and seizure outcomes in iEEG

Published: June 2024

AbstractObjectiveA third of the patients who undergo intracranial EEG (iEEG) for seizure‐onset zone (SOZ) localization do not proceed to resective surgery for epilepsy, and over half of those who do continue to have seizures following treatment. To better identify candidates who are more likely to see benefits from undergoing iEEG, we investigated preoperative and iEEG peri‐operative features associated with the localization of a putative SOZ, undergoing subsequent surgical treatment, and seizure outcomes.MethodsWe conducted a retrospective cohort study of consecutive patients who underwent iEEG from 2001 to 2022 at two institutions. Outcomes included SOZ identification, proceeding to surgical treatment (resection vs. neuromodulation), and subsequent seizure freedom.ResultsWe identified 329 unique patients who were followed for a median of 3.9 (IQR:7) years, with a minimum of 2‐year follow‐up for seizure outcomes analyses. Multivariate analysis identified lateralized and lobar localization on scalp EEG (OR 3.8, p = 0.001) to be associated with SOZ localization. Patients with unilateral localization on scalp EEG (OR 3.0, p = 0.003), unilateral preimplantation hypothesis (OR 3.1, p = 0.001), and lesional preoperative MRI (OR 2.1, p = 0.033) were more likely to undergo resection than neuromodulation. Similarly, a unilateral pre‐implantation hypothesis (OR 2.6, p < 0.001) favored seizure freedom, whereas prior neuromodulation (OR 0.3, p = 0.013) decreased the odds. Larger number of preoperative anti‐seizure medications (ASMs) did not influence seizure freedom rates but did decrease favorable (Engel I, II) seizure outcomes (OR 0.7, p = 0.026).InterpretationNon‐invasive localization data prior to iEEG are associated with subsequent resection and seizure freedom, independent of iEEG localization. Factors predictive of SOZ localization are not necessarily predictive of post‐operative seizure freedom.
Parameter learning of multi‐input multi‐output Hammerstein system with measurement noises utilizing combined signals
Authors: Li Feng , Sun Xueqi , Cao Qingfeng 
Published: June 2024

SummaryIn this article, the parameter learning scheme for the multi‐input multi‐output (MIMO) Hammerstein nonlinear systems under measurement noises is studied, which is derived by exploiting the correlation analysis and data filtering technique. The coupled MIMO Hammerstein system presented involves a static nonlinear subsystem modeled by neural fuzzy model (NFM), and a dynamic linear subsystem established by autoregressive moving average with extra input (ARMAX) model. To learn the unknown parameter of the MIMO Hammerstein system, the combined signals are designed to realize that identification of the nonlinear subsystem is separated from that of linear subsystem. First, the correlation properties of separable signals in a nonlinear system are analyzed, then the parameters of the linear subsystem are estimated utilizing correlation analysis, which can deal with the issue of unmeasured intermediate variable in the Hammerstein system. Second, the data filtering technique is introduced to derive the data filtering‐based recursive least squares technique for learning the nonlinear subsystem parameter, which can reduce the impact of the moving average noise and improve the precision of parameter estimation. Finally, the effectiveness and feasibility of the proposed identification scheme is proved by numerical simulation and nonlinear pH process.

AbstractCarbon dots (CDs) are ideal fluorophores for optoelectronic devices. However, it is still a great challenge to obtain CDs with high solid‐state photoluminescence quantum yields (PLQYs). In this work, it is first reported that the barium‐doped CDs (Ba‐CDs), which can be simply synthesized on a large scale via a direct one‐step heating approach using an open vessel. The as‐synthesized Ba‐CDs exhibit ultrabright luminescence both in liquid and solid states. The as‐synthesized Ba‐CDs with a scale of 8.6 g per batch show a Stokes shift of ≈0.68 eV and high PLQYs of 80.8% and 66.8% in liquid and solid state, respectively. Interestingly, an efficient fluorescence enhancement phenomenon occurs when Ba‐CDs are mixed with polyvinylpyrrolidone (PVP), which reveals the critical issue of compatibility between CDs and polymer matrix can be well resolved. As a proof‐of‐concept, the Ba‐CDs are employed as fluorophores for high‐efficiency luminescent solar concentrator (LSC) fabrication. The Ba‐CDs@PVP‐based LSC has a PLQY of 88.78%, showing a breakthrough optical conversion efficiency of 7.16% and power conversion efficiency of 6.87% under natural light irradiation (40 mW cm−2). The results demonstrate the potential application of the ultrabright Ba‐CDs in efficient photovoltaic devices.

AbstractThe study shows that, in waveguide (WG) configuration, the coupling of a 2D plasmonic metamaterial grating (MMG) having a conventional Bragg period along the guide but a distinct period along the transverse axis can lead to Electromagnetically‐Induced‐Transparency (EIT) behavior. This epitomizes that metamaterials, as functional photonic building blocks, can lead to low losses in many standard devices if properly designed. The study reported the observation in passive WGs of a marked Fano‐type EIT resonance with record high‐quality factor: Q = 5000 and contrast >20 dB. Unlike any standard metal grating, MMG‐assisted waveguides exhibit strong grating coupling strength and low‐loss properties simultaneously. This concept is further applied to demonstrate single‐frequency‐emission electrically‐injected Distributed Feedback (DFB) lasers in the near‐infrared telecom domain. The key point is that laser emission occurs at the peak of EIT, i.e., the maximum in transmission. It therefore addresses one of the main critical issues of DFB lasers related to the single frequency yield. The laser performances are state‐of‐the‐art (Ith < 20 mA, Pmax > 20 mW at I = 200 mA, SMSR > 50 dB, optical feedback tolerance >−21 dB compliant with IEEE 802.3 standard). The presented approach, compatible with existing industrial technologies, is promising for real‐life telecom applications.

Published: June 2024

AbstractRechargeable sodium‐ion batteries are promising sustainable energy storage systems, owing to their low cost and high energy density. However, the existing cathode chemistries, particularly layered sodium transition metal oxides, exhibit restricted electrochemical performance, which hinders their extensive applications. To overcome challenges, originating from kinetically limited structural transformations, various cation substitutions are reported in the literature. Especially the partial Na–K replacement is discussed recently, which can increase bulk Na‐diffusivity and suppress undesirable phase transitions. Here, a critical study of potassium doping in different layered materials P3‐K0.5Co0.33Mn0.67O2 and P3‐K0.5Co0.33Mn0.67O2*0.5H2O with redox‐active Co (and Mn), and P2‐Na0.7Co0.8Ti0.2O2 and P2‐K0.1Na0.7Co0.8Ti0.2O2 with Co activity is presented. It is found that the presence of K significantly enhances the moisture sensitivity: P3‐K0.5Co0.33Mn0.67O2*0.5H2O is quickly formed in the air from K0.5Co0.33Mn0.67O2, while Na0.7Co0.8Ti0.2O2 remains stable under the same conditions. In electrochemical Na‐cells, a partial K–Na cation exchange in P3‐K0.5Co0.33Mn0.67O2 and P3‐K0.5Co0.33Mn0.67O2*0.5H2O occurs without applying current. The electrochemical performance of P3‐K0.5Co0.33Mn0.67O2 is slightly increased in comparison to K‐free P2‐Na0.67Co0.33MnO.67O2 from the literature, staying, however, behind the performance of Na0.7Co0.8Ti0.2O2. K0.1Na0.7Co0.8Ti0.2O2 shows weaker rate capability than isostructural Na0.7Co0.8Ti0.2O2, reflecting a negative impact of K on Na‐diffusivity. Therefore, effect of K‐incorporation in layered structures on the battery performance strongly depends on the cathode composition.

AbstractOrganic optoelectronics have attracted widespread interdisciplinary research interest but lags far behind in the application in marine environmental detection. The organic photoelectrochemical transistor (OPECT) shows promise as a powerful tool for comprehensive monitoring and early warning of marine conditions, which can be further enhanced by the valuable signal amplification strategy of nanozyme‐mediated catalytic precipitation. Herein, OPECT technology is integrated with nanozyme‐mediated catalytic precipitation for the first time, establishing an ultrasensitive detection platform for okadaic acid (OA). Specifically, MXene@MnIn2S4 (MXMnIS) hybrid composed of Schottky‐junction is synthesized via a hydrothermal method, which can efficiently modulate the device with high current gain. Linking with a sandwich immunoassay, the Ru‐C3N4 nanozyme with peroxidase‐mimicking activity can catalyze the oxidation of 4‐chloro‐1‐naphthol (4‐CN) to form an insoluble precipitate on the electrode surface, resulting in a decrease in the photocurrent and altering the transistor response. Importantly, the proposed OPECT biosensor presented an excellent sensitivity and a low detection limit (32.5 pM), fully satisfying the fundamental requirements for the quantitative detection of intracellular and extracellular OA in the practical culture media of Prorocentrum lima at different growth stages. This OPECT platform based on the nanozyme‐mediated quenching effect is significant for effectively monitoring the safety of the marine ecological environment and food safety.

AbstractEmerging intrinsically flexible fully π‐conjugated polymers (FπCPs) are a promising functional material for flexible optoelectronics, attributed to their potential interchain interpenetration and entanglement. However, the challenge remains in obtaining elastic–plastic FπCPs with intrinsic robust optoelectronic property and excellent long‐term and cycling deformation stability simultaneously for applications in deep‐blue flexible polymer light‐emitting diodes (PLEDs). This study, demonstrates a series of elastic‐plastic FπCPs (P1–P4) with an excellent energy dissipation capacity via side‐chain internal plasticization for the ultra‐deep‐blue flexible PLEDs. First, the freestanding P1 film exhibited a maximum fracture strain of 34.6%. More interestingly, the elastic behavior is observed with a low strain (≤10%), and the stretched film with a high deformation (>10%) attributed to plastic processing revealed the robust capacity to realize energy absorption and release. The elastic–plastic P1 film exhibits outstanding ultra‐deep‐blue emission, with an efficiency of 56.38%. Subsequently, efficient PLEDs are fabricated with an ultra‐deep‐blue emission of CIE (0.16, 0.04) and a maximum external quantum efficiency of 1.73%. Finally, stable and efficient ultra‐deep‐blue electroluminescence are obtained from PLEDs based on stretchable films with different strains and cycling deformations, suggesting excellent elastic–plastic behavior and deformation stability for flexible electronics.

Abstract2D hybrid perovskites have emerged as a promising alternative material to address the environmental stability and the ion‐migration of the 3D perovskites for direct X‐ray detector applications. Nevertheless, the X‐ray detection performance of the 2D hybrid perovskites still lags because of its low X‐ray attenuation ability and limited solubility for thick film deposition. Here, a high‐performance X‐ray detector in Dion‐Jacobson 2D hybrid perovskite, 2(aminomethyl) pyridinium lead bromide (2AMPPbBr4), is studied. 2AMPPbBr4 exhibits an ultra‐short interlayer distance of 3.43 Å, leading to high X‐ray attenuation ability. Furthermore, DFT results indicate that 2AMPPbBr4 exhibits type II band alignment between 2AMP2+ ligand and the [PbI6]4− layers, facilitating effective spatial separation of photo‐generated carriers. The X‐ray detector made of 2AMPPbBr4 with an average thickness of 200 µm is realized via an improved drop‐casting method. An improved X‐ray sensitivity of 3933.88 µC Gy−1 cm−2 and a low detection limit of 4.17 nGy s−1 is achieved. This work paves the way for high‐performance X‐ray detectors based on the emerging 2D perovskite materials.

AbstractBiSCl, which shares the anisotropic chain‐like lattice configuration with the BiVXVIYVII (XS, Se; YCl, Br, I) family displays high photoelectric conversion efficiency in the UV–vis wavelength region. The current difficulty in 2D growth restricts the investigation of device performance and further integration. Herein, an epitaxial growth strategy for 2D BiSCl is proposed based on the principle of sharing a chloridion layer at the BiSCl/BiOCl interface. The interfacial atomic arrangement is carefully revealed using atomic resolved AC‐TEM(Spherical Aberration High Transmission Electron Microscope) and demonstrated by calculations based on density functional theory. Benefiting from its compatibility with PS‐assisted large‐scale transfer technology, the photoelectric performance is evaluated by constructing a standard symmetrical photoconductor and Graphene‐BiSCl Schottky junction device. High responsivity (1.71 × 104 A W−1) and detectivity (5.9 × 1016. Jones) are achieved at 405 nm, and robustness is shown in a broadband spectrum, which manifested prominent anisotropic photoelectric behavior and great potential in weak‐light detection. These results elucidate the photoelectric applications of BiSCl semiconductors and the structural design of the BiVXVIYVII family.

Published: June 2024

AbstractThiocarbamoyl fluoride is an understudied fluorinated group, mainly due to the paucity of data on its properties. Herein, an in‐depth study of the stability of thiocarbamoyl fluorides, especially under near‐physiological conditions, is described. Since efficient and easy to implement syntheses of these compounds are still under‐described, a new method, based on the use of a trifluoromethanesulfenamide, a well‐described reagent, has also been developed. This trifluoromethanesulfenamide turned out to be able to generate in situ difluorothiophosgene, which was able to react rapidly with amines to provide various thiocarbamoyl fluorides.
