Secure adaptive fuzzy tracking control for a class of nonlinear systems under actuator and sensor faults and denial‐of‐service attacks based on event‐triggered mechanism
Authors: Baghi Hamidreza , Abdollahi Farzaneh , Talebi Heidar Ali 
Published: December 2024

AbstractThe main focus of this article is to investigate the secure adaptive fuzzy tracking control (SAFTC) scheme for a class of uncertain nonlinear systems, with special presence of actuator and sensor faults and denial‐of‐service (DoS) attacks. The proposed method integrates switching gain observers, fuzzy logic systems (FLS), and event‐triggered control and introduces a new algorithm and dynamic gain to optimize tracking performance and resilience against disturbances, multiple faults, and DoS attacks. In addition, it is demonstrated that the proposed control scheme ensures the closed‐loop system remains bounded and the error signal asymptotically converges to a neighborhood around the origin. Finally, results for the proposed method applied to a class of unknown nonlinear systems are presented to back theoretical results and their effectiveness.
Three‐stage receding horizon‐based voltage control and electric vehicle charge scheduling of active distribution networks
Authors: Dutta Arunima , Ganguly Sanjib , Kumar Chandan 
Published: December 2024

AbstractIn this article, a three‐stage, two‐level voltage regulation scheme based on receding horizon control (RHC) principles is proposed for active distribution networks. The distribution system consists of photovoltaic (PV) generators, electric vehicles (EVs), and electrical loads. Electric vehicle aggregators (EVA) act as intermediary between the prosumers and the network operators. The devised framework aims to coordinate various voltage control equipment according to their slow response (1st stage) or fast (2nd stage) response to voltage variations. In the 3rd stage, the electric vehicle charge scheduling is accomplished and all these stages constitute to form upper‐level operation. Further, an effort has been made to maximize the profit of EVA for performing ancillary services during EV charge scheduling. Moreover, EVAs incorporate demand response programs to enhance network stability. While 1st and 2nd stages are formulated as non‐linear programming problems, the 3rd stage is formulated as a mixed‐integer non‐linear problem. The problems are optimized using the CPLEX solver in the general algebraic modeling system (GAMS) environment. The lower control level is implemented by following a few rules that adjust the local Q(V) characteristics embedded in the power electronics interfaced devices. The obtained results exhibit that the devised framework not only helps in voltage regulation but also the EV owners and the EVA. Later, the profit earned by EVAs is computed for slow and fast charging schemes.
Vaccination against Respiratory Infections in the Immunosenescent Older Adult Population: Challenges and Opportunities
Authors: Ecarnot Fiona , Maggi Stefania 
Published: December 2024

AbstractRespiratory infections are associated with a huge burden of disease every year and disproportionately affect older adults, namely those aged 65 years and older. Older adults are at increased risk of infections compared with their younger counterparts, and once infected, have a higher risk of experiencing severe disease course, complications, and long-term sequelae. Therefore, vaccination is clearly a key strategy to prevent infection and its attendant negative consequences. We review here the burden of common respiratory diseases in older adults, namely influenza, pneumococcal disease, and respiratory syncytial virus. We then review some of the challenges facing immunization of older adults, namely immunosenescence, inflammaging, and low vaccine uptake. Next, potential opportunities for overcoming these challenges are reviewed, including the use of higher antigen doses and/or adjuvants in vaccine formulations for older adults, and the potential of multiomics analyses to improve development, performance, and implementation of vaccines.

Introduction Metastatic CRC is considered as a heterogenous disease. Its management is therefore complex and dynamic. In order the give a ready reference to community oncologists, we developed this real world recommendations.
Methods A group of experts with academic background and real world experience in mCRC got together. We reviewed the current literature and the insights gained from our real world experience. Based on the same we put together these recommendations.
Recommendations (Results) Molecular testing should be done wherever possible. Most of these patients will be treated with a palliative approach. Doublet chemotherapy is a long-standing standard of care. Triplet therapy may be offered where a more aggressive approach is indicated. Combination with anti -vascular endothelial growth factor antibodies and/or anti EGFR antibodies is also considered standard. In the first-line setting, pembrolizumab can be used for patients with mCRC and microsatellite instability-high or deficient mismatch repair tumours; Left and right sided tumours are distinct entities. Combination of chemotherapy and targeted therapy is used as per individual patient and tumour characteristics.Oligometastatic disease can be approached with potentially curative intent. Cytoreductive surgery plus chemotherapy can be offered to selected patients with peritoneal only metastases. Stereotactic body radiation therapy can be used as local therapy for patients with oligometastatic liver only disease who cannot be taken up for surgery. New strategies include induction-maintenance chemotherapy and perioperative chemotherapy. All drugs/ regimen included as standard of care in the first line can also be used in subsequent lines. Specific targetable driver mutation tumours can be treated accordingly with their complementary biological therapy.
Conclusion Multidisciplinary team management and shared decision making are possible when patient and caregivers choose to become active participants.
Percutaneous Interventions for Gallstones: Techniques and Outcomes
Authors: Husnain Ali , Usman Amir , Riaz Ahsun 
Published: December 2024

AbstractApproximately 6% of the global population has gallstones. Acute cholecystitis affects approximately 200,000 individuals annually in the United States. Laparoscopic or open cholecystectomy is the definitive treatment, but many patients are ineligible due to comorbidities. For these high-risk patients, percutaneous cholecystostomy is a temporary alternative; however long-term use in patients with continued contraindications to surgery affects quality of life and has a high complication rate. Percutaneous cholecystoscopic lithotripsy/lithectomy has emerged as a viable alternative for managing these patients. Recent advancements in endoscopic and lithotripsy devices have enhanced outcomes. This review will discuss the technical aspects and outcomes of percutaneous gallstone lithotripsy/lithectomy (in the gallbladder and bile ducts).
Quotation headlines in the printed British quality press
Authors: Fetzer Anita 
Published: December 2024

Abstract
News discourse comes along with the presumption of newsworthiness, and this also holds for one of its constitutive
parts: headlines. This paper adopts a discourse-pragmatic perspective to the formatting and discursive function of quotation
headlines in the printed British quality press. It addresses (1) the constitutive parts and felicity conditions of quotation;
(2) its linguistic formatting as direct, indirect, scare, mixed and mixed type, and its signalling with metadata, and (3) its
uptake and (re)contextualisation in the news story. In the data, quotation headlines are signalled linguistically with quotatives
and typographically with single quotation marks, colons or empty spaces. Their uptake in the news story is signalled with double
typographic quotation marks and supplemented with metadata (participants, local, temporal and discursive coordinates). As for
their discursive functions, quotations not only import context into the news discourse, but their mention also implies that some
prior, taken-for-granted contextualisation requires re-negotiation.

Abstract
A high saturation magnetic flux density (B
s) is essential for the development of Fe-based amorphous alloys for electromagnetic devices and motors. However, achieving a high B
s often compromises the glass-forming ability (GFA) of Fe-based amorphous alloys. This study investigates the effects of ferromagnetic elements (Fe, Co, and Ni) on the microstructure and magnetic properties of Fe86B7C7 amorphous alloys through experiments and ab initio molecular dynamics simulations. By analyzing both the experimental and simulation results, the relationship between the atomic structures, GFA, and magnetic properties of these amorphous alloys was determined. The results indicate that the GFA of the alloys is correlated with the proportion of icosahedral and body-centered cubic clusters. The addition of Co and Ni not only improved the GFA of the alloys but also effectively increased the overall magnetic moment with an appropriate amount of Co and a small amount of Ni. This increase in the magnetic moment primarily arises from the enhancement of the magnetic moment of Fe atoms, resulting from the redistribution between the spin-up and spin-down electrons of Fe-3d orbits, as well as the strong exchange interactions between Fe and Co and Fe–Ni pairs. The results obtained offer valuable insights into the correlation between the atomic structure and magnetic properties of these amorphous alloys and suggest potential directions for the optimization of Fe-based amorphous alloys.

Published: December 2024

Abstract
With the rapid development of intelligent manufacturing, data-driven deep-learning techniques have been widely used in bearing fault diagnosis. However, the problem of unbalanced data samples usually occurs in actual production environments due to the difficulty of collecting comprehensive fault data covering multiple fault types and degrees, which directly affects the diagnosis performance. For this reason, this paper proposes a new method for simulation data-driven bearing fault diagnosis. In this paper, based on the vibration mechanism of rolling bearings, a fault signal simulation model that can accurately simulate different damage degrees of inner and outer rings is constructed. The model cannot only effectively extend the data set but also generate simulated signals that are highly consistent with accurate fault signals in terms of amplitude modulation characteristics in the absence of actual samples. This paper conducts experiments on the CWRU rolling bearing fault dataset by combining the generated simulation data with deep learning methods. The experimental results show that the model’s classification accuracy reaches 98.7% and 93.7% in the case of a small number of samples (small sample scenario) and no actual samples (no sample scenario), respectively. In addition, we conducted experiments with multiple working conditions on a testbed built in the laboratory, and all of them also achieved excellent results.

Published: December 2024

Abstract
The extraction of the center points of light stripes is crucial for line-structured light three-dimensional (3D) measurement systems. High-precision center point extraction requires first determining the cross-sectional orientation of the light stripe. However, most researchers treat this as an independent segment of structured light 3D measurement and incur significant costs in calculating the light stripe’s normal vector, making it challenging to simultaneously meet the requirements of efficiency, high precision, and robustness. This paper presents a sub-pixel light stripe center point extraction method utilizing light plane calibration information. By projecting the normal of the light plane obtained during the system calibration onto the imaging plane, the direction for center point searching is obtained. Subsequently, sub-pixel expansion is performed to precisely locate the center point of the light stripe. The proposed method optimizes the center detection process without introducing additional measurement stages, reducing computational costs and enhancing interference resistance. The simulation analysis and experiments conducted demonstrate that the proposed method achieves higher accuracy and robustness with minimal time consumption, validating its effectiveness.
A method for identifying and compensating the installation pose of cycloidal gears based on a gear measuring center

Published: December 2024

Abstract
The accurate evaluation of the manufacturing errors of the cycloidal gear is a prerequisite for ensuring the high transmission accuracy of cycloidal-pin reducers. However, due to the inevitable installation errors during measurement, the measurement model is inconsistent with the evaluation datum, resulting in distorted actual evaluation results that cannot accurately reflect the actual tooth profile condition. Meanwhile, the lack of professional software also makes compensating installation errors a difficult problem for accurately assessing manufacturing errors. In view of this, a compensation method for the installation error of the cycloidal gear is proposed based on the gear measuring center. By identifying and compensating the actual installation pose of the cycloidal gear, the evaluation of manufacturing errors is more accurate and can better reflect the real machining condition of the tooth profile. By constructing and analyzing the error measurement model of the cycloidal gear, the evaluation coordinate system for the manufacturing error is clarified, thereby ensuring that the evaluation datum is consistent with the measurement datum. The mathematical model of the actual installation pose of the cycloidal gear is established by accurately describing the installation axis vector and the installation center position. Based on this, the accurate evaluation of manufacturing error is achieved in the workpiece coordinate system by establishing the conversion relationship between the measurement coordinate system and the evaluation coordinate system. Finally, the correctness of the method proposed in this paper is verified through comparison experiments of the measurement and the significance analysis. The practice shows that the method has good flexibility, which can not only accurately evaluate the manufacturing error of the cycloidal gear but also provide technical support for the precise measurement of complex parts such as bevel gears and gear cutters.

Published: December 2024

Abstract
A B-spline adaptive sampling (B-SAS) method is proposed for three-dimensional freeform surface measurements using a laser differential confocal sensor (LDCS). High-precision focusing on optical freeform surfaces was achieved by axial scanning using the LDCS. The B-SAS method, based on the arc length and curvature uniformity, was introduced to enable the adaptive distribution of sampling points on freeform surfaces. Experiments show that the B-SAS method improves the repeatability accuracy of the peak-to-valley (PV) (3σ) for freeform surfaces by 27% compared to the uniform sampling method, and the corresponding measurement efficiency is improved by 41%. The repeatability accuracy of the PV (3σ) and root-mean-square (3σ) of the measured surfaces, using the B-SAS method, are lower than 27 and 8.5 nm, respectively. This method realizes highly accurate and efficient freeform surface measurements and provides a solution for measuring freeform surfaces with large angles.

Abstract
We present a sequential growth scheme based on pulsed laser deposition, which yields dense arrays of ultrathin, match-shaped Au/CoNi nanopillars, vertically embedded in SrTiO3 thin films. Analysis of the magnetic properties of these nanocomposites reveals a pronounced out-of-plane anisotropy. We show that the latter not only results from the peculiar nanoarchitecture of the hybrid films but is further enhanced by strong magneto-structural coupling of the wires to the surrounding matrix. Finally, we provide a detailed overview of the optical response of these vertical nanostructures. Combining ellipsometry measurements with finite-difference time-domain simulations allows us to assess the potential of our self-assembly approach, as well as its possible shortcomings, for producing hybrid thin films with well-tailored magneto-plasmonic properties.

Published: December 2024

Abstract
We comment on the reply by Shiraishi et al to our comments regarding their recently published study ‘Modeling for Predicting Survival Fraction of Cells after Ultra-High Dose Rate Irradiation’. While we appreciate the effort of the authors to consider our comments, we see ourselves compelled to add another short comment as we believe that some of our suggestions have been misrepresented. This may have resulted in a misguiding re-evaluation of the model.
Investigation of triangularity effects on tokamak edge turbulence through multi-fidelity gyrokinetic simulations
Authors: Hoffmann A C D , Balestri A , Ricci P 
Published: December 2024

Abstract
This paper uses the gyro-moment (GM) approach as a multi-fidelity tool to explore the effect of triangularity on tokamak edge turbulence. Considering experimental data from an L-mode DIII-D discharge, we conduct gyrokinetic (GK) simulations with realistic plasma edge geometry parameters at ρ = 0.95. We find that employing ten GMs effectively captures essential features of both trapped electron mode (TEM) and ion temperature gradient (ITG) turbulence. By comparing electromagnetic (EM) GK simulations with adiabatic electron GK and reduced fluid simulations, we identify the range of validity of the reduced models. We observe that TEMs drive turbulent heat transport under nominal discharge conditions, hindering accurate transport level estimates by both simplified models. However, when TEMs are absent, and turbulence is ITG-driven, an agreement across the different models is observed. Finally, a parameter scan shows that the positive triangularity scenario destabilizes the TEM, therefore, the adiabatic electron model tends to show agreement with the EM simulations in zero and negative triangularity scenarios. On the other hand, the reduced fluid simulations exhibit limited sensitivity to triangularity changes, shedding light on the importance of retaining kinetic effects to accurately model the impact of triangularity turbulence in the tokamak edge. In conclusion, our multi-fidelity study suggests that a GM hierarchy with a limited number of moments is an ideal candidate for efficiently exploring triangularity effects on micro-scale turbulence.

Published: December 2024

Abstract
Magnetoresistance oscillations in semiconductor quantum wells, with the semi-parabolic plus semi-inverse squared potential, under the influence of intense electromagnetic waves (IEMW), is studied theoretically. Analytical expression for the longitudinal magnetoresistance (LMR) is derived from the quantum kinetic equation for electrons, using the Fröhlich Hamiltonian of the electron-acoustic phonon system. Numerical calculation results show the complex dependence of LMR on the parameters of the external field (electric, magnetic field and temperature) as well as the structure parameters of the confinement potential. In the absence of IEMW, Shubnikov-de Haas (SdH) oscillations appear with amplitudes that decrease with temperature in agreement with previous theoretical and experimental results. In the presence of IEMW, the SdH oscillations appear in beats with amplitudes that increase with the intensity of the IEMW. SdH oscillations under the influence of electromagnetic waves are called microwave-induced magnetoresistance oscillations. The maximum and minimum peaks appear at the positions where the IEMW frequencies are integer and half-integer values of the cyclotron frequency, respectively. In addition, the structural parameters of the quantum well such as the confinement frequency and the geometrical parameters have a significant influence on the LMR as well as the SdH oscillations. When the confinement frequency is small, the two-dimensional electronic system in the quantum well behaves as a bulk semiconductor, resulting in the absence of SdH oscillations. In addition, the LMR increases with the geometrical parameter β

z
of the quantum well. The obtained results provide a solid theoretical foundation for the possibility of controlling SdH oscillations by IEMW as well as the structural properties of materials in future experimental observations.
