Authors: Main Russell M. , Vornholt Simon M. , Rice Cameron M. , Elliott Caroline , Russell Samantha E. , Kerr Peter J. , Warren Mark R. , Morris Russell E.
Published: March 2023

Metal-organic frameworks (MOFs) are well known for their ability to adsorb various gases. The use of MOFs for the storage and release of biologically active gases, particularly nitric oxide (NO) and carbon monoxide (CO), has been a subject of interest. To elucidate the binding mechanisms and geometry of these gases, an in situ single crystal X-ray diffraction (scXRD) study using synchrotron radiation at Diamond Light Source has been performed on a set of MOFs that display promising gas adsorption properties. NO and CO, were introduced into activated Ni-CPO-27 and the related Co-4,6-dihydroxyisophthalate (Co-4,6-dhip). Both MOFs show strong binding affinity towards CO and NO, however CO suffers more from competitive co-adsorption of water. Additionally, we show that morphology can play an important role in the ease of dehydration for these two systems.

Blockchain‐based reliable image copyright protection
Authors: Xiao Xiangli , He Xiaotong , Zhang Yushu , Dong Xuewen , Yang Lu‐Xing , Xiang Yong
Published: March 2023

The indiscriminate distribution of a large number of unlicensed images through the Internet seriously harms the benefits of image owners, which prompts the study of image copyright protection solutions. Existing blockchain‐free solutions are limited to using centralized servers to store copyright information, leaving data vulnerable to being lost or tampered with by external attacks. Although the blockchain‐based image copyright protection solutions are capable of addressing the above problem, improvements are needed in choosing a suitable blockchain platform and supporting integrated copyright life cycle management. To this end, this paper designs a blockchain‐based reliable image copyright protection system named BB‐RICP using Hyperledger Fabric. For one thing, the adoption of Fabric mitigates the limitations of other blockchain platforms represented by Ethereum in terms of efficiency, economy, and availability. For another, BB‐RICP successes in achieving integrated copyright lifecycle management. In addition, BB‐RICP achieves enhanced applicability performance by firstly introducing GM algorithms recommended by Chinese national standard and adapting the more consortium blockchain‐oriented practical byzantine fault tolerance algorithm. Moreover, the adoption of spread spectrum watermarking brings convenience to users. Finally, Kubernetes is used to assist in the simulation of BB‐RICP to verify that users can operate reliably in the blockchain network.
Calibration of frequency response mismatches in time‐interleaved analog‐to‐digital converter based on adaptive method
Authors: Xiang Jingrui , Tian Shulin , Pan Huiqing
Published: March 2023

The time‐interleaved analog‐to‐digital converter (TIADC) system could achieve high sampling rate effectively, but the frequency response inconsistency among channels will introduce frequency response mismatches, which will seriously degrade the signal quality. In this paper, a novel multi‐channel frequency response mismatches adaptive calibration method is proposed. The frequency response of the compensation filter is expanded into a polynomial of a digital differentiator, and the least mean square adaptive strategy is used to calibrate frequency response mismatches. It does not require measuring the channel frequency responses in advance and uses digital post‐processing technology to effectively compensate the frequency response of the multi‐channel TIADC system and improve the spurious‐free dynamic range. The experimental results verify the effectiveness of the algorithm.
Resource allocation method for Mobility‐Aware and Multi‐UAV‐Assisted mobile edge computing systems with energy harvesting
Authors: Chen Yong , Zhao Yisheng , He Ximei , Xu Zhihong
Published: March 2023

Due to the limited coverage of base station (BS) and battery capacity of mobile users, the resource allocation strategy in multiple unmanned aerial vehicles (UAVs)‐assisted edge computing system with nonlinear energy harvesting is investigated in this paper. The cooperation between BS and multi‐UAV is considered, which can provide extensive coverage for users with mobility. Mobile users can simultaneously offload computation bits to the BS and the UAV, and mobile users harvest energy from BS and UAV. Meanwhile, the mobility of users is taken into account. Moreover, an echo state network (ESN)‐based prediction algorithm is utilized for predicting the future positions of mobile users. Therefore, the UAV can reach the predicted users' positions in advance to ensure the continuity of communication. The objective of the resource allocation strategy is to maximize the energy efficiency by jointly optimizing bandwidth allocation, computation resources, the trajectory of UAV, and transmitting power of mobile users. Then, the resource allocation problem is formulated as a mixed‐integer nonlinear programming problem. The quantum‐behaved particle swarm optimization (QPSO) algorithm is used to solve the problem. Simulation results demonstrate that the proposed strategy can achieve higher energy efficiency than other benchmark strategies. In addition, QPSO algorithm outperforms the standard particle swarm optimization algorithm and genetic algorithm in terms of energy efficiency.
Design of robust adaptive fuzzy control for uncertain bilateral teleoperation systems based on backstepping approach
Authors: Bouteraa Yassine , Alattas Khalid A. , Peng Tongrui , Fekih Afef , Rahmani Reza , Mobayen Saleh
Published: March 2023

In this study, a novel method based on a robust adaptive fuzzy control approach is developed for nonlinear teleoperation systems. Its main objectives are to ensure system stability and properly mitigating parametric uncertainties stemming from external disturbances and un‐modelled dynamics. For the communication channel, instead of the direct transmission of environmental torque signals, the approximated environmental parameters by the fuzzy system are transmitted to the master side for the prediction of environmental torque, thus successfully avoiding the transmission of the power signals in the delayed communication channel and solving the passivity problem in the teleoperation system. Besides, a trajectory generator is employed in the master side, whereas a trajectory smoothing is provided in the slave side. Theoretically, it was proven that both position tracking and force feedback problems are attained. Using Lyapunov stability analysis, this work illustrates that the robust adaptive fuzzy controller based on the backstepping approach guarantees the system's asymptotic stability. Simulation results confirm the efficiency of the suggested control technique in achieving the stability and tracking objectives of the uncertain nonlinear teleoperation system.
Spectral similarity‐based feature for hyperspectral image classification
Authors: Wang Ke , Xiao Jian
Published: March 2023

Based on spectral similarity measure, a unified spectral similarity‐based framework is developed to generate a new series of spectral similarity‐based features for hyperspectral image classification by using classifier, such as support vector machine(SVM). First, a reference spectral signature was defined according to the original hyperspectral data. The reference spectral signature can be chosen as the uniform line or the average of the original data. Second, the proposed features were produced by calculating the spectral similarity measures between each pixel's and the reference spectral signature. The experiment result shows that these proposed features can improve hyperspectral image classification accuracies.
A hybrid sliding mode control scheme for rapid earth fault current limiters in compensated distribution networks in bushfire prone areas
Authors: Roy Tushar Kanti , Mahmud Md Apel , Nasiruzzaman A B M , Barik MdAbdul
Published: March 2023

A hybrid sliding mode controller is proposed for rapid earth fault current limiters (REFCLs) used in resonant grounded power distribution networks to self‐extinguish powerline bushfires where the concepts of the proportional integral (PI) action and nonsingular fast terminal sliding surface (NFTSS) are combined together to utilize the benefits of both schemes. A hybrid sliding surface is designed for obtaining the control input so that the fault current compensation is achieved by the residual current compensation (RCC) inverter used within a REFCL to a value that the fire does not ignite. The inclusion of an integral action along with the NFTSS helps to significantly reduce the chattering effect. Furthermore, a continuous function is introduced within the proposed scheme to replace the discontinuous signum function. The switches for the RCC inverter are controlled by deriving control actions from the Lyapunov stability theory applied on the hybrid PI‐NFTSS. The performance of the proposed controller is compared with a nonsingular fast terminal sliding mode controller. For this reason, this paper also includes the design process of nonsingular fast terminal sliding mode controller which is designed using only the NFTSS. Simulations under different scenarios having different fault resistances clearly depict the superiority of the proposed scheme over the nonsingular fast terminal sliding mode controller and an existing integral sliding mode controller in terms of maintaining transient responses.
Design and analysis of multi‐layer SIW coupler to use in phased array antenna feed network
Authors: Abedi Hamid , Taskhiri Mohammad Mahdi , Hadian Ebrahim
Published: March 2023

In this paper, a directional coupler is designed using the substrate integrated waveguide (SIW) method. The SIW coupler consists of a double‐layer with transverse rectangular slots in the middle of two layers. The proposed coupler contains three ports. The placement of ports is considered based on the generalization of the power divider network. Each layer is printed on 0.508 mm Rogers RT/Duroid 5880 ( and ). The coupling level is basically controlled by the number and size of the slots. This coupling ratio changes from −5 dB to −13 dB. It is complicated to design a single‐layer feed network for a two‐dimensional phased array antenna. The designed SIW coupler can be easily generalized to the feed network for a 2D phased array antenna that consists of a large number of antenna and phase shifter elements. The SIW coupler is simulated using CST software. The results of the analyses, simulations and experiments indicate good performances of the designed coupler.
GOODS-ALMA 2.0: Last gigayear star formation histories of the so-called starbursts within the main sequence

Recently, a population of compact main sequence (MS) galaxies exhibiting starburst-like properties were identified in the GOODS-ALMA blind survey at 1.1 mm. Several evolution scenarios were proposed to explain their particular physical properties (e.g., compact size, low gas content, short depletion time). In this work, we aim to study the star formation history (SFH) of the GOODS-ALMA galaxies to understand whether or not the so-called ‘starbursts (SBs) in the MS’ galaxies exhibit a star formation activity over the last gigayear that is different from that of the MS galaxies and that could explain their specificity. We use the CIGALE SED modelling code to which we add nonparametric SFHs. To compare the recent SFHs of the galaxies quantitatively, we define a parameter, the star formation rate (SFR) gradient, which provides the angle showing the direction that a galaxy has followed in the SFR-versus-stellar-mass plane over a given period. We show that SB in the MS galaxies show positive or weak negative gradients over the last 100, 300, and 1000 Myr, which is at odds with a scenario where these galaxies would be transitioning from the SB region at the end of a strong starburst phase. Normal GOODS-ALMA galaxies and “SB in the MS” galaxies show the same SFR gradient distribution, meaning that they have similar recent SFHs despite their different properties (compactness, low depletion time). The “SBs in the MS” galaxies manage to maintain their star-formation activity, allowing them to stay within the MS. This points toward a diversity of galaxies within a complex MS.
Fluctuations in heavy ion collisions and global conservation effects
Authors: Poberezhnyuk Roman , Vovchenko Volodymyr , Savchuk Oleh , Koch Volker , Gorenstein Mark , Stoecker Horst
Published: March 2023

Subensemble is a type of statistical ensemble which is the generalization of grand canonical and canonical ensembles. The subensemble acceptance method (SAM) provides general formulas to correct the cumulants of distributions in heavy-ion collisions for the global conservation of all QCD charges. The method is applicable for an arbitrary equation of state and sufficiently large systems, such as those created in central collisions of heavy ions. The new fluctuation measures insensitive to global conservation effects are presented. The main results are illustrated in the hadron resonance gas and van der Waals fluid frameworks.
ψ(2S) production and nuclear modification factor in nucleus–nucleus collisions with ALICE
Authors: Hushnud H.
Published: March 2023

Charmonium production is sensitive to deconfinement in nucleusnucleus collisions. The production via regeneration within the QGP or at the phase boundary has been identified as an important ingredient for the description of the centrality and transverse momentum dependence (pT) of the J/ψ nuclear modification factor (RAA) at the LHC. ψ(2S) production relative to J/ψ is one possible discriminator between the two different regeneration scenarios. At the LHC. there is so far no significant observation of the ψ(2S) in central nucleus-nucleus collisions at low-pT, where regeneration is expected to play an important role. The combined Run 2 data set of ALICE allows one to extract a significant ψ(2S) signal in this kinematic region at forward rapidity, in the dimuon decay channel. In this contribution, we present for the first time results on the ψ(2S)-to-J/ψ single ratio and double ratio (to pp collisions) as well as the ψ(2S) nuclear modification factor, in Pb-Pb collisions at √SNN = 5.02 TeV. The ψ(2S)-to-J/ψ double ratio and ψ(2S) RAA are calculated using a new proton-proton reference with improved precision. Results are compared with model calculations.
Heavy-flavor meson and baryon production in high-energy nucleus-nucleus collisions
Authors: Beraudo A. , De Pace A. , Alfonso D. Pablos , Prino F. , Monteno M. , Nardi M.
Published: March 2023

We present a new model for the description of heavy-flavor hadronization in relativistic heavy-ion collisions. We explore its effect on the charmed hadron yields and kinematic distributions once the latter is applied at the end of transport calculations used to simulate the propagation of heavy quarks in the deconfined fireball produced in the collision. The model is based on the formation of color-singlet clusters through the recombination of charm quarks with light antiquarks or diquarks from the same fluid cell. This local mechanism of color neutralization leads to a strong space-momentum correlation, which provides a substantial enhancement of charmed baryon production and of the collective flow of all charmed hadrons.
Measurement of the production of (anti)(hyper)nuclei
Authors: Pinto Chiara
Published: March 2023

In recent years, ALICE has extensively studied the production of light (anti)(hyper)nuclei in different collision systems and center-of-mass energies. Nevertheless, the production mechanisms of light (hyper)nuclei is still unclear and under intense debate in the scientific community. Two classes of models are typically used to describe nuclear production: the statistical hadronisation model and the coalescence ones. In heavy-ion collisions, both models describe well the production yields of light nuclei and their ratios to the yields of hadrons, making it difficult to distinguish between the two. On the contrary, small collision systems, such as pp and p–Pb collisions, are ideal to study the (anti)(hyper)nuclei production mechanisms, thanks to the large separation between the different predictions. In this paper, recent results on light nuclei production measured with ALICE at the LHC in small collision systems are discussed in the context of the nucleosynthesis models, allowing us to exclude some configurations of the SHM and coalescence models in order to set tighter constraints to the available theoretical predictions.
Photoelectrochemical Cerium Catalysis via Ligand-to-Metal Charge Transfer: A Rising Frontier in Sustainable Organic Synthesis
Authors: Wang Yuying , Liu Siyuan , Chen Jianbin , Han Jiangsheng , Wang Ling
Published: March 2023

Photoelectrochemical cerium catalysis is an emerging and rapidly developing strategy in organic synthetic. A sustainable platform is being constructed by combining the concerted energy transfer from light and electricity to cerium with the ligand-to-metal charge transfer of excited state CeIV species. With this powerful strategy, hard to oxidized substrates can be activated under mild conditions, contributing to broad functional group compatibility. Such as, carboxylic acids, alcohols, and the Cl anion can deliver the corresponding radicals via formal single electron transfer (SET) with a low oxidation potential. Further cooperation with other synthetic strategies, including alkoxy radical promoted hydrogen atom transfer (HAT) and β-scission, leads to the functionalization of inert C(sp
3)–H, Si–H, and C–C bonds via a mild radical pathway. In this review, recent advances in photoelectrochemical cerium catalysis are described. More importantly, as this field features some unique advantages, but is rarely explored, we hope chemists will pay more attention to this catalytic system.

Background The role of temporal lobe epilepsy (TLE) in determining personality traits and neurobehavioral symptoms, collectively known as the interictal behavioral syndrome (also known as Geschwind syndrome or “Gastaut-Geschwind syndrome”), as well as the syndrome's association with the particular artistic expression of many epileptic litterateurs are well known in neurology and psychiatry. A deepening of emotionality along with a serious, highly ethical, and spiritual behavior have been described as positive personality changes among patients with chronic mesial-TLE.

Objectives Our narrative-based clinical hypothesis aims at contributing to the ongoing debate on the association between TLE and artistic expression, as well as the latter's supposed implication for epileptology in general and the neuropsychology of epilepsy in particular.

Methods Through an analysis of the biography, language, and literary work of Greek novelist Demosthenes Voutyras, we hypothesize that his mystical and dark writing style could be attributed to medial temporal interictal dynamics.

Conclusions We suggest that the psycholiterary profile of Voutyras is consistent with the idiosyncratic characteristics of the temporal lobe personality, while a non-dominant temporal lobe contribution has been proposed.

Oral cavity cancers contribute to a majority of cancers in India. Clinical examination alone cannot determine the deeper extent of the disease; therefore, need for cross-sectional imaging including computed tomography and magnetic resonance imaging becomes indispensable for pre-treatment evaluation to decide optimal plan of management. Oral cavity squamous cell cancers (OSCC) can be treated with surgery alone, whereas deep muscle, neurovascular, osseous, or nodal involvement on imaging suggests advanced disease that requires a combination of surgery, radiation, and/or chemotherapy. Because of the complex anatomy of the oral cavity and its surrounding structures, imaging is crucial for locoregional staging and early detection of distant metastases. Imaging plays indispensable role not only in diagnosis but also in planning the management. An optimal guideline paper for developing countries like India is lacking that not only helps standardize the management but will also assist oncologists make reasonable decisions and reduce the unnecessary imaging. This imaging guideline paper will discuss the optimal imaging in diagnosis and management OSCC for Indian subcontinent.

Introduction: Autologous costal cartilage framework placement is currently the gold standard in patients with microtia. In this article, we present the modifications developed by the author, generally following the principles established by Nagata, and discuss the technical details that have led us to achieve consistently stable and good long-term outcomes for auricular reconstruction in microtia.

Materials and Methods: A retrospective review of microtia reconstruction performed from 2015 to 2021 was done. Those who underwent primary reconstruction for microtia and with a minimum follow-up of 6 months with documented photographs were included. Those who underwent secondary reconstruction for microtia and those who did not follow-up for a minimum period of 6 months were excluded. Outcomes were assessed with regard to appearance, and durability of the result. Influence of certain changes like delaying reconstruction until 15 years of age, use of nylon for framework fabrication, etc. over the outcome were assessed.

Results: Of 11 ears reconstructed at less than 15 years of age, only one patient (9%) had a good long-term outcome, whereas of the 17 ears reconstructed at greater than 15 years of age, nine patients (53%) had a good long-term outcome. In our experience, infections and wire extrusions were the significant events related to severe cartilage resorption.

Conclusion: In our experience, delaying the first stage to 15 years or later, using double-armed nylon sutures, and reducing the projection of the third layer of the framework in select cases have helped to improve our outcomes. Second stage of reconstruction can be avoided if patient is satisfied with the projection achieved in the first stage.

A method of post-acquisition upsampling for scanning x-ray microscopy is developed in this study to improve the spatial resolution beyond the Nyquist frequency as determined by the intervals of a raster scan grid. The proposed method is applicable only when the probe beam size is not negligibly small compared with the pixels that constitute a raster micrograph—the Voronoi cells of a scan grid. The unconvoluted spatial variation in a photoresponse is estimated by solving a stochastic inverse problem at a higher resolution than that at which the data are acquired. This is followed by a rise in the spatial cutoff frequency due to a reduction in the noise floor. The practicability of the proposed method was verified by applying it to raster micrographs of x-ray absorption in Nd-Fe-B sintered magnets. The improvement thus achieved in spatial resolution was numerically demonstrated via spectral analysis by using the discrete Fourier transform. The authors also argue for a reasonable decimation scheme for the spatial sampling interval in relation to an ill-posed inverse problem and aliasing. The computer-assisted enhancement in the viability of scanning x-ray magnetic circular dichroism microscopy was illustrated by visualizing magnetic field-induced changes in domain patterns of the Nd2Fe14B main-phase.

Ternary semiconductors such as InGaN thin films, quantum wells, and superlattices commonly exhibit alloy fluctuations that become increasingly pronounced with higher In-content. The thickness fluctuations of quantum wells and their thin cap-layers further introduce nanoscale inhomogeneities that alter the potential landscape. In this work, we present a combined theoretical and experimental study of InGaN single quantum wells with thin GaN cap-layers to unravel the influence of cap-layer thickness, compositional inhomogeneity, and thickness fluctuations on their electronic and optical properties. A pronounced spectral shift of quantum well emission for thin cap-layers between 1 and 10 nm is observed by micro-photoluminescence spectroscopy. The origin of this shift is explained by calculations of electronic band profiles and probability density overlap of carriers in the quantum well. The impact of alloy fluctuations and homogeneity for different cap-layer thicknesses is studied on both the microscale and nanoscale using UV micro-Raman scattering and tip-enhanced Raman spectroscopy (TERS). On the microscale, the alloy composition as determined by micro-Raman mapping appears very homogeneous except for the thinnest 1 nm cap-layer where small fluctuations are visible. On the nanoscale, TERS reveals local fluctuations on a 20–30 nm length scale. The influence of the cap-layer thickness on the TERS spectra is discussed regarding both the nanoscale homogeneity and the depth resolution of the near-field Raman scattering technique. Our results demonstrate the capabilities of TERS to resolve nanoscale thickness fluctuations and compositional inhomogeneities in ultra-thin semiconductor layers, even when they are buried by thin cap-layers with thicknesses below 10 nm.

Poiseuille–Rayleigh–Bénard (PRB) flow has been observed in nature as well as many industrial applications. Enhancing the rate of heat transfer of PRB flow has long been a subject of interest in the relevant research. This study proposed a novelty non-intrusive method to control PRB flow through numerical simulations by using jets generated by nine groups of alternating-current dielectric-barrier-discharge (AC-DBD) plasma actuators arranged in the spanwise direction. We considered PRB flows (Pr = 2/3) in air in channels with an aspect ratio equal to length/height = 20, with Reynolds numbers in the range of 10 ≤ Re ≤ 100 and a Rayleigh number of Ra = 10 000. The effect of plasma control on PRB flow was qualitatively and quantitatively analyzed. The results showed that at a low Reynolds number (Re = 10, 20, 30), the jet generated by the plasma actuators promoted the plume on the wall to form stable transversal rolls and enhance mixed convection. At a high Reynolds number (Re = 50, 100), the jet suppressed Poiseuille flow, promoted the rise in the flow of heat at the bottom wall, and enhanced the vertical temperature gradient. Moreover, steady DBD plasma actuation-based control significantly improved the coefficient of heat transfer of the flow, at times providing up to a tripling of transport compared to the unactuated case. The results here are useful for technological and industrial applications.
Spin wave excitations in a nanowire spin Hall oscillator with perpendicular magnetic anisotropy

Published: March 2023

Spin torque oscillators (STOs) are emerging microwave devices that can potentially be used in spin-logic devices and the next-generation high-speed computing architecture. Thanks to their non-linear nature, STOs are easily tunable by the magnetic field and the dc current. Spin Hall nano-oscillators are promising types of STOs and most of the current studies focus on localized modes that can be easily excited. Here, we study using micromagnetic simulations, the nature of the spin-torque-induced excitations in nanowire devices made of perpendicular magnetic anisotropy (PMA) materials. Our results showed that, upon including PMA, the excitation of localized and propagating spin wave modes is feasible. We study the nature of the mode excitations as a function of the PMA strength (Ku) and the current. Indeed, we estimate a critical value of Ku to allow for the excitation of the propagating spin wave. We attribute this mode selectivity between localized and propagating modes to the magnitude and the change of the sign of the nonlinearity of the system from negative to positive at a non-zero Ku, which is supported by analytical calculations. Our results provide deep insight into engineering microwave devices for future magnonic and computational applications.

The high-mode generator is a passive device operating at low power, which is helpful for the mode converter test. It has generally served as the input of the mode converter to evaluate the performance. Here, we realized the design of the TE25,10 mode generator. The multi-section coaxial resonator was designed to improve the TE25,10 mode purity. Two mirrors were used to excite the TE25,10 mode resonance based on the geometric optics. The construction of the TE25,10 mode generator was realized. The purity of the measured TE25,10 mode was 91%, which was in good agreement with the theory.

Compositional diffusion at interfaces often occurs during the synthesis of heterostructures, which poses a significant challenge to the reliability and performance of heterostructure-based electronic devices. In this study, the effect of interfacial compositional diffusion on the interfacial phonon transport in GaN/AlN heterostructures has been explored using molecular dynamics and phonon dynamics simulations. It is found the compositional diffusion results in a remarkable reduction in the interfacial thermal conductance (ITC) of the heterostructures, which can be modulated by tuning the compositional diffusion thickness. Phonon wave packet simulations further revealed that the energy transmission coefficient across the interface is strongly phonon frequency-dependent and interfacial morphology-dependent, which is consistent well with the calculated ITC of the structures. The phonon mode conversion and phonon localization are observed at the region of interfaces. Furthermore, it is found that the longitudinal acoustic phonons are more sensitive to the compositional diffusion interface than transverse-acoustic phonons do. However, it is interesting to find that the energy transmission coefficients of transverse-acoustic phonons with a high frequency (above 3.6 THz) across the compositional interface are abnormally higher than those across the sharp interface due to the stronger phonon mode conversion in the compositional diffusion region, which provides additional pathways for energy transmission. Our findings provide a deeper insight into the interfacial phonon scattering and transmission under the coupling effect of interfacial morphology and compositional diffusion.
