An adaptive control scheme against state‐dependent sensor attacks and input‐dependent actuator attacks in cyber‐physical systems
Authors: Wang Xiao , Zhao Ping 
Published: March 2023

AbstractThe application of cyber‐physical systems (CPSs) in many areas is threatened by its embedded structure. This paper considers the design of an adaptive controller for linear CPSs against deception attacks. Specifically, a corrective signal is designed to suppress or offset the impact of sensor and actuator attacks, especially when the controller and the correction signal are also attacked. First, an adaptive controller is developed for time‐invariant deception attacks and further extended to time‐varying deception attacks. In each case, state‐independent sensor attacks and input‐independent actuator attacks, as well as state‐dependent sensor attacks and input‐dependent actuator attacks, are discussed. For the considered closed‐loop system with time‐invariant state‐dependent sensor attacks and input‐dependent actuator attacks, the controller the authors developed ensures the asymptotic stability of the systems. For the other three cases of the corresponding system, the controllers are also designed, which ensures uniform ultimate boundedness. Finally, several numerical examples are given to explain the availability of our control scheme.
A low‐profile wide‐angle scanning ultrawideband tightly coupled dipole array without any wide‐angle impedance matching layer
Authors: Geng Yuan , Yang Deqiang 
Published: March 2023

AbstractThe present is a low‐profile, wide‐angle scanning, ultrawideband, tightly coupled dipole array that lacks a wide‐angle impedance matching layer and lossy materials. Impedance matching will deteriorate at the lower end of the operating bandwidth due to the influence of the ground plane. A well‐designed perforated balun is used to achieve better impedance matching. Moreover, parasitic metallic strips are attached to the dipole's side to add additional reactive components. According to the results of simulations, the impedance bandwidth of the array, which ranges from 0.67 to 2.83 GHz, and its wide‐angle scanning capability, which scans 75° in the E‐plane and 45° in the H‐plane, both achieve good performance when the voltage standing wave ratio is less than 3. The profile of the array is only 0.0581λlow above the ground plane, where λlow is the wavelength at the lowest operating frequency. The proposed array's simulated results are validated by fabricating and measuring an 8 × 8 prototype array.

Aims. We report the discovery and characterisation of the transiting mini-Neptune HD 207496 b (TOI-1099) as part of a large programme that aims to characterise naked core planets.Methods. We obtained HARPS spectroscopic observations, one ground-based transit, and high-resolution imaging which we combined with the TESS photometry to confirm and characterise the TESS candidate and its host star.Results. The host star is an active early K dwarf with a mass of 0.80 ± 0.04M⊙, a radius of 0.769 ± 0.026R⊙, and aGmagnitude of 8. We found that the host star is young, ~0.52 Gyr, allowing us to gain insight into planetary evolution. We derived a planetary mass of 6.1 ± 1.6M⊕, a planetary radius of 2.25 ± 0.12R⊕, and a planetary density ofρp= 3.27−0.91+0.97g cm−3.Conclusions. From internal structure modelling of the planet, we conclude that the planet has either a water-rich envelope, a gas-rich envelope, or a mixture of both. We have performed evaporation modelling of the planet. If we assume the planet has a gas-rich envelope, we find that the planet has lost a significant fraction of its envelope and its radius has shrunk. Furthermore, we estimate it will lose all its remaining gaseous envelope in ~0.52 Gyr. Otherwise, the planet could have already lost all its primordial gas and is now a bare ocean planet. Further observations of its possible atmosphere and/or mass-loss rate would allow us to distinguish between these two hypotheses. Such observations would determine if the planet remains above the radius gap or if it will shrink and be below the gap.
Aktuelles zu Schwangerschaften bei entzündlich-rheumatischen Erkrankungen

Was ist neu?
Planung von Schwangerschaften Fragen der Familienplanung sind
ein wichtiger Bestandteil in der Betreuung von Patientinnen mit entzündlich-rheumatischen
Erkrankungen. Die Thematik sollte frühzeitig angesprochen werden. Eine sorgfältige Planung
führt nachweislich zu mehr erfolgreichen und komplikationsarmen Schwangerschaften. Zunehmend
in den Fokus rückt das Screening nach Risikofaktoren für eine Präeklampsie, da sich hieraus
die Indikation zu einer prophylaktischen Einnahme von niedrig dosiertem Aspirin ab der
Frühschwangerschaft ergeben kann. Neuere Empfehlungen unterstützen dabei praxisnah.
Schwangerschaftsverlauf Bei Frauen mit Rheumatoider Arthritis
oder Spondyloarthritis, die mit biologischen krankheitsmodifizierenden antirheumatischen
Medikamenten (bDMARDs) behandelt werden, sollte eine Fortsetzung der Medikamentengabe während
der Schwangerschaft in Betracht gezogen werden, um das Risiko eines Krankheitsschubs und
nachteiliger Schwangerschaftsfolgen zu reduzieren. Bei SLE-Schwangerschaften bietet eine
HCQ-Therapie mit einer Reduktion des Risikos einer Präeklampsie und eines kongenitalen
AV-Blocks einen Benefit, der über die reine Krankheitskontrolle hinausgeht.
Therapie vor, in und nach der Schwangerschaft Eine stabile
Erkrankung unter schwangerschaftskompatibler Medikation stellt einen der wichtigsten
prädiktiven Faktoren für einen guten Schwangerschaftsverlauf dar. Die Evidenz zur Sicherheit
von antirheumatischen Therapien steigt stetig. Aktuelle Empfehlungen sollten in der Beratung
beachtet werden.
Stadieneinteilung von Nierenkrankheiten heute und morgen
Authors: Boss Kristina , Kribben Andreas 
Published: March 2023

Was ist neu?
Neue Nomenklatur für Nierenfunktion und Nierenkrankheiten. Seit 09/2022 gibt es ein neues, deutschsprachiges Glossar zur Nomenklatur von Nierenfunktion und Nierenkrankheit, abgestimmt auf internationale Fachtermini und KDIGO-Leitlinien zur präziseren und einheitlichen Beschreibung der Sachverhalte. Begriffe wie ,,Nierenerkrankung“, „Niereninsuffizienz“ oder ,,Akutes Nierenversagen“ sollten vermieden und durch ,,Krankheit“ oder ,,Funktionseinschränkung“ ersetzt werden.
Bedeutung von Cystatin C bei der Stadieneinteilung von Nierenkrankheiten. Die KDIGO-Leitlinie empfiehlt bei Patienten im CKD-Stadium G3a, neben der Bestimmung von Serumkreatinin, die zusätzliche Bestimmung von Cystatin zur Bestätigung des CKD-Stadiums. Eine Kombination von Serumkreatinin und Cystatin C zur Abschätzung der GFR ohne Berücksichtigung des sog. Race-Koeffizienten scheint bei African Americans präziser zu sein als die bisherigen eGFR-Formeln. Es gibt dazu aber noch keine Empfehlungen in internationalen Leitlinien. Für Kaukasier ändert sich die Formel nicht.
Akute Nierenkrankheit (AKD). Eine Nierenfunktionseinschränkung, die mehr als 7 Tage, aber weniger als 3 Monate besteht, wird als akute Nierenkrankheit (AKD) bezeichnet. Die AKD-Phase ist das kritische Zeitfenster für therapeutische Maßnahmen zur Verringerung des Progressionsrisikos bei Nierenkrankheiten.
Die nächsten Schritte in der Stadieneinteilung und Graduierung von Nierenkrankheiten. Eine zukünftige, erweiterte AKI-Definition unter Einbeziehung von Biomarkern ermöglicht die Einteilung von Patienten in Subklassen nach funktionellen und strukturellen Einschränkungen und bildet so die Zweidimensionalität des AKI ab. Durch Nutzung von Künstlicher Intelligenz können große Datenmengen aus klinischen Parametern, Blut- und Urinproben, histopathologischen und molekularen Markern (u.a. Proteomik- und Metabolomikdaten) zur Graduierung einer CKD integrativ genutzt werden und so wesentlich zu einer individuellen Therapie beitragen.

Published: March 2023

AbstractSinonasal tumors are a relatively rare and heterogeneous group of tumors. Owing to their nonspecific presentation and rarity, they can be potentially overlooked resulting in delayed diagnosis and management, and increased patient morbidity. Imaging is crucial for the detection, staging, surgical planning, follow-up as well as surveillance of sinonasal masses, wherein computed tomography (CT) and magnetic resonance imaging (MRI) play complementary roles. CT is better at depicting bony changes, while MRI is useful for delineating the extent of soft tissue lesion, detect perineural, intracranial, or intraorbital spread as well as differentiate trapped sinus secretions from tumor tissue. Other modalities like fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) and arteriography can be selectively employed. FDG-PET is useful for metastatic workup and detection of residual/ recurrent disease. Arteriography and endovascular image-guided interventions are useful to delineate supply of vascular tumors and perform preoperative embolization. A systematic evidence-based approach to a possible case of sinonasal tumor can go a long way in streamlining the detection and management of these tumors, while optimizing the use of available healthcare resources.
Immigration policy congruence and political trust: a cross-national analysis among 23 European countries
Authors: Simon Stephan 
Published: March 2023

AbstractThis study examines how immigration policy impacts citizens’ trust in politicians and political institutions. The article argues that immigration policy affects political trust through policy congruence. More specifically, it claims that the level of restrictiveness of immigration policy impacts political trust heterogeneously, conditional on whether citizens are anti- or pro-immigration and additionally on how strongly citizens are seeking information about political issues, the latter making it potentially easier for them to identify policy (in-)congruencies. Combining country-level data on immigration policy outputs in European countries with individual-level data to complex multilevel models, the findings reveal that the level of congruence of immigration policy to citizens’ immigration preferences alone does not impact political trust. But they show that immigration policy impacts the political trust of citizens who are highly anti-immigration and at the same time very strongly seeking political information. Overall, however, the article concludes that the impact of immigration policy congruence on political trust is moderate at best.
Extended x-ray absorption fine structure measurement of ramp compressed Ti using laser-irradiated metallic foil as x-ray source on SGIII prototype laser facility

Published: March 2023

Laser-irradiated metallic foils were considered as x-ray sources for extended x-ray absorption fine structure (EXAFS) measurements and confirmed by experiments on the SGIII prototype facility. The Au foils were irradiated by laser beams with a total energy of 2.77 kJ and full width at half maximum (FWHM) of 1 ns to create an x-ray source. The x-ray emission was spectrally smooth in the energy range of Ti EXAFS, the FWHM of Au foil x-ray radiation pulse in the energy range of 0.1–4000 eV was 0.99 ns, and the FWHM of x-ray pulse in the energy range of 5000–6000 eV was deduced to be 0.55 ns according to simulation results. A shaped laser pulse was designed to achieve the Ti sample’s laser-direct-driven ramp compression process. By creating a quasi-stable state lasting longer than 1 ns as the probing window during the compression process, the demand for temporal resolution was reduced. EXAFS spectra of compressed Ti in α and ω-phase were obtained and compared, and structural phase transition was verified by EXAFS pattern changes. The velocity of the back interface of the Ti sample was measured by the velocity interferometer system for any reflector, and the maximum of the deduced pressure in the middle of the Ti sample was 8.2 GPa, which is consistent with the α-ω phase transition.
Integrated monolingualism and audism governing Spanish Sign-Language users’ self-determination in the legal
system
Authors: Monzó-Nebot Esther , González-Montesino Rayco H. 
Published: March 2023

Abstract
Many legal systems have begun to adjust their social and linguistic practices to accommodate non-dominant social
groups. However, linguistic diversity is often framed as an exception, and interpreters are viewed as a service to address these
exceptions rather than as part of broader structural changes to enable access to justice. This article explores the access to and
participation in the Spanish legal system of Spanish Sign-Language users (SSLUs) who are deaf or heard of hearing. Through
semi-structured interviews with SSLUs, the article elicits their perceptions of the legal field. These data are analyzed from the
perspective of self-determination theory (Deci and Ryan 1985) to identify how SSLUs’
psychological needs of competence, autonomy, and relatedness are linked to the social, cultural, and economic capital invested and
distributed through social practices. The goal is to clarify how SSLUs’ habitus sustains or resists monolingual and audist
ideologies establishing hierarchies between language communities.
Self-progress aggregate learning for weakly supervised salient object detection
Authors: Sun Wanchun , Feng Xin , Liu Jingyao , Ma Hui 
Published: March 2023

Abstract
The task of salient object detection aims to find the most salient object from the samples. In the field of weakly supervised learning, the existing weakly supervised salient object detection (WSSOD) methods often fail to utilize the limited label information (such as self-affinity or edge features, and scale transform) for learning. Therefore, this paper proposes a self-progress aggregate learning method named SPAL. First, the feature optimization scheme of the edge information module is put forward based on analysis of the problems existing in the current convolutional neural network for detection of the edge information of the object. Obviously, the salient object has a low requirement for high-level information, In particular, in order to improve the utilization rate of the network structure without increasing its complexity, the affinity global context is design in view of the particularity of the structure of a salient object. The structure of a salient object not only depends on the deep-level semantic feature information to a certain extent, but also has a certain guiding effect on the object position and edge information. Second, high-level affinity information is used to complement the slight-level edge information globally, and the scale attention module is adopted to guide the network to adapt the multi-scale reinforcement feature learning ability for the salient object regions. Our method SPAL achieved better experimental results than the other competitive models for comparison on five benchmark data sets (i.e. for DUTS-TEST, compared with CCFNet our method achieved an improvement of 0.6% for mean absolute error (MAE), 5.1% for Fb, and 1.1% for Eℰ
), which demonstrates the effectiveness of our proposed method.
Dynamics and performance evaluation of a vortex-induced vibration energy harvester with hybrid bluff body
Authors: Li H T , Ren H , Shang M J , Lv Q , Qin W Y 
Published: March 2023

Abstract
To investigate the influence of bluff body with a variable section on the vortex-induced vibration (VIV) energy harvesting performance, a series of hybrid cylinders are designed and a quantitative comparison is presented. The basic elements of hybrid bluff body are the D-shaped (D) and original circular-shaped cylinders (O), and the length ratio between the O-shaped part and the D-shaped part is fixed. According to the arrangement order, three kinds of hybrid bluff bodies are termed as ODO, ODODO and DOD. A distributed model is developed and the numerical simulation is carried out to verify the response. Corresponding wind tunnel experiments are conducted, and the results reveal that compared to the bluff body with a circular cylinder, the hybrid bluff bodies such as ODODO and DOD can enhance the VIV and thus increase the output significantly. Moreover, the lock-in regions with the ODODO and DOD shapes will increase by 12.5% and 62.5%, respectively. However, the results also indicate that some type of arrangement such as ODO will suppress the energy harvesting performance. Furthermore, the computational fluid dynamics method is employed to reveal the physical mechanism of flow field around the hybrid bluff body. The results show that the integration of D-shape prism in a cylinder along an axial direction could influence aerodynamics. A faster boundary layer separation occurs for the VIV energy harvesters with the hybrid cylinders of ODODO and DOD, which could improve the energy conversion efficiency from flow-induced vibrations. However, the aerodynamic force is restricted and response is suppressed as a D-shaped cylinder is sandwiched between two O-shaped cylinders.
Photo-electrochemical water splitting and electrochemical performance of silicon nanowire arrays
Authors: Kadhim Z J , Mahdi M A 
Published: March 2023

Abstract
Silicon nanowires (SiNWs) were prepared using n-Si(100) by a simple two-step metal-assisted chemical etching (MACE) approach with different durations of 15 and 30 min. Surface morphology, structural, and optical properties of prepared SiNWs were investigated using Scanning Electron Microscope (SEM), x-ray diffraction (XRD) and UV–vis absorption, respectively. Under visible light, a photoelectrochemical cell (PEC) was used to measure the properties of a photoanode device that was fabricated based on n-SiNWs for splitting water. At 0.78 V, the SiNWs that were prepared in 30 min had a photocurrent density of 3.72 mA.cm−2 and a photoconversion efficiency (η) of 1.37%. Cyclic voltammetry (CV) measurements showed that both the n-Si(100) wafer and the n-SiNWs that were made with etching times of 15 and 30 min showed faradaic behavior with redox peaks. Electrochemical impedance spectroscopy (EIS) showed that the SiNWs photoanode prepared with 30 min of etching time had a charge transfer resistance of 3112.3. This is low enough to make it easy for charge to move across the interface. The Mott-Schottky (M-S) analysis revealed a high concentration of carriers of 4.77 × 1021 cm−3 at the working electrode/electrolyte interface,

Published: March 2023

Abstract
We report ulsrasonic measurements of the density and bulk modulus of propylene glycol at room temperature and at the temperature of liquid nitrogen up to a pressure of 1.4 GPa. We perform molecular dynamics simulations with two different force fields—COMPASS and Charmm. We show that the COMPASS force field reproduces the experimental data with high accuracy. For this reason we employ this force field to analyze the microstructure and hydrogen bonding in the system. We find that the number of hydrogen bonds does not depend on pressure.

Published: March 2023

Abstract
We experimentally demonstrate an all-fiber passively Q-switched erbium-doped laser based on a microsphere resonator coated with Co2+:ZnSe film, which can achieve multi-wavelength pulse laser. With electron beam evaporation technology, the saturable absorber (SA) with a modulation depth of 55% was prepared by depositing Co2+:ZnSe film on the microsphere for the loss modulation of the laser cavity. The passively Q-switched output pulses were obtained by inserting the SA into the laser cavity and the narrowest pulse width of ∼3 μs was obtained. The fiber laser can stably output quintuple-wavelength laser pulses with a 3 dB bandwidth of ∼0.1 nm. The wavelength interval of multi-wavelengths was stably maintained at ∼1 nm and the smallest optical signal-to-noise ratio of ∼10 dB at the pump power of 400 mW was measured. The signal-to-noise ratio was ∼58 dB, which confirms excellent output stability. The results prove that it is a promising SA device to achieve passively Q-switched multi-wavelength pulse fiber lasers.
Numerical Simulation of Flow Over Airfoil and Its Optimization
Authors: Xu Rick E. , Wu Zhe 
Published: March 2023

Abstract
Airfoils are one of the most important factors in determining an airplane’s ability to fly. As such, their optimization holds important ramifications for the continual need to improve airplane performance. In this paper, the optimization of airfoil design is explored through numerical computational fluid dynamics. This paper first investigates the effects of Angle of Attack on airfoil lift/drag ratios, which is shown to have a significant influence on the performance of airfoils. Then, the effects from thickness are explored, and it is found that the influence of thickness is highly dependent on the specific shape of airfoil. In addition, in order to further improve airfoil aerodynamic performance, a type of modified airfoil with an additional tip is developed and simulated. The results indicate that airfoils with additional tips can perform better, but only with the proper combination of tip parameter values. For example, the modified airfoil with a tip of 0.03 L length at a 25° tip angle bested that same airfoil without an additional tip. Finally, it is found that the Backpropagation machine-learning algorithm, when trained with prior simulation data, can quickly predict lift and drag coefficients of airfoils. The results in this paper could facilitate the further optimization of airfoil design.

Abstract
The accuracy of wind flow simulation in mountain area in micro-topography is related to discrete scheme, turbulence model and wall function. In this paper, the standard hill model is adopt to analyze the calculation accuracy of different turbulence models. Four turbulence models, including RNG k-ε, k-ω, SST k-ω and TSST k-ω, were used in the calculation, and were compared with the result of wind tunnel test. The calculation results with the second-order upwind scheme, the SST or TSST turbulence model and the scalable wall function are basically consistent with results of wind tunnel test.
