Published: February 2023

AbstractFuture distribution networks (DN) are subject to rapid load changes and high penetration of variable distributed energy resources (DER). Due to this, the DN operators face several operational challenges, especially voltage violations. Optimal power flow (OPF)‐based reactive power control (RPC) from the smart converter (SC) is one of the viable solutions to address such violations. However, sufficient communication and monitoring infrastructures are not available for OPF‐based RPC. With the development of the latest information communication technology in SC, cyber‐physical co‐simulation (CPCS) has been extensively used for real‐time monitoring and control. Moreover, deploying OPF‐based RPC using CPCS considering the controller design of SC for a realistic DN is still a big challenge. Hence, this paper aims to mitigate voltage violations by using OPF‐based RPC in a real‐time CPCS framework with multiple SCs in a realistic DN. The OPF‐based RPC is achieved by performing the CPCS framework developed in this study. The CIGRE medium‐voltage DN is considered as a test system. Real‐time optimization and signal processing are achieved by Python‐based programs using a model‐based toolchain of a real‐time DN solver and simulator. Real‐time simulation studies showed that the proposed method is capable of handling uncertain voltage violations in real time.

AbstractOwing to increased energy demand, renewable energy sources have recently reached greater heights in the power industry. In this regard, integrating renewable energy with the power grid system has become essential in meeting consumer's energy demands. The novelty in this article is the design of an advanced Aalborg inverter with a reduced number of switches which results in enhanced system performance by reducing the switching losses. Integrating renewable energy sources with the power grid network has gained massive importance in supplying electric power to consumers. Integrating the power grid with renewable energy has become possible with the implementation of grid tie inverters. The only drawback in implementing renewable energy sources with the power grid is that the output of the resources varies from time to time in nature. Voltage Source Inverter‐based grid system requires two or three‐stage inverters for interfacing power units to transfer DC energy into the power grid network. To reduce the switching frequency across the system, many new excellent inverters have been designed to ensure the healthy operation of the system operating at a higher frequency. This article has been coined with the investigation of a novel buck and boosts converter‐based inverter operation named Aalborg inverter. The inverter operates at a higher frequency and minimum voltage drop across the inductor, where only one power stage has been implied to enhance the system's reliability and efficiency. This novel Aalborg inverter is applied and investigated for photovoltaic application.
Modified Dorsal Split Preservation Hybrid Rhinoplasty for Cartilaginous Pushdown and Full Letdown Applications: A PROM-Based Review of 100 Consecutive Cases
Authors: Robotti Enrico , Cottone Giuseppe , Leone Francesco 
Published: February 2023

AbstractSplitting the middle vault on an anatomical plane along the “Septal T” allows a new hybrid perspective on the many modifications of “surface” preservation techniques. The “dorsal split preservation” concept can be applied both to cartilaginous pushdown as well as to full letdown techniques. The dorsal keystone area is maintained, while the middle vault is reshaped. The septum is addressed by conventional L strut septoplasty. Precise direct suture fixation of the high-middle strip is easily accomplished after flexing the osseous-chondral junction at the K area. Specific technical points are described to allow exact and stable configuration of the dorsum.A retrospective analysis on 100 consecutive patients demonstrated aesthetic and functional improvement.

Abstract
Introduction With increasing incidence of facial skin cancer, more patients undergo facial reconstruction following Mohs micrographic surgery (MMS). Aesthetically unpleasing, thickened facial flaps, and disturbing scars can be treated with a pressure mask with inner silicone lining to help improve functional and aesthetic outcomes. However, data on long-term patient satisfaction and quality of life (QoL) following this treatment are lacking.
Methods We aimed to assess long-term satisfaction and QoL of patients who underwent local flap reconstruction following MMS. Patients treated between January 2012 and October 2020 were invited to answer FACE-Q and SCAR-Q questionnaires. Demographic data, skin cancer type and location, type of reconstruction, postoperative complications, duration of pressure mask therapy, daily compliance, and additional scar treatment were collected to explore possible predictors.
Results Of 92 eligible patients, 50 responded. Eighteen respondents were male (36%) and 32 were female (64%). Mean duration of pressure mask therapy was 10.20 ± 4.61 months. Patients were 61.14 ± 32.91 months after completion of pressure mask therapy upon participation. Patients whose reconstruction consisted of multiple flaps had significantly worse outcomes in social function (p = 0.012), scar appearance (p = 0.045), and scar symptoms (p = 0.008). A trend of increasing time since therapy completion predicting better outcomes was observed for all scales, and it was a significant predictor for better scar appearance (p = 0.001) and less scar symptoms (p = 0.001).
Conclusion Pressure mask treatment for facial flaps and scars following MMS results in good long-term patient satisfaction and QoL. Multiple local flaps, reflecting a larger skin defect postexcision, is a predictor for worse outcomes in social function, scar appearance, and symptoms. Increasing time is associated with increasing satisfaction, which reflects satisfactory and stable long-term effects of treatment, possibly combined with more acceptance of the result over time.

Published: February 2023

AbstractSkeletal muscle is a highly plastic tissue that can alter its metabolic and
contractile features, as well as regenerative potential in response to exercise
and other conditions. Multiple signaling factors including metabolites, kinases,
receptors, and transcriptional factors have been studied in the regulation of
skeletal muscle plasticity. Recently, estrogen-related receptors (ERRs) have
emerged as a critical transcriptional hub in control of skeletal muscle
homeostasis. ERRα and ERRγ – the two highly expressed
ERR sub-types in the muscle respond to various extracellular cues such as
exercise, hypoxia, fasting and dietary factors, in turn regulating gene
expression in the skeletal muscle. On the other hand, conditions such as
diabetes and muscular dystrophy suppress expression of ERRs in the skeletal
muscle, likely contributing to disease progression. We highlight key functions
of ERRs in the skeletal muscle including the regulation of fiber type,
mitochondrial metabolism, vascularization, and regeneration. We also describe
how ERRs are regulated in the skeletal muscle, and their interaction with
important muscle regulators (e. g. AMPK and PGCs). Finally, we identify
critical gaps in our understanding of ERR signaling in the skeletal muscle, and
suggest future areas of investigation to advance ERRs as potential targets for
function promoting therapeutics in muscle diseases.

AbstractWe report a concise and green total synthesis of 1,4-dideoxy-1,4-imino-l-arabinitol hydrochloride from naturally occurring d-xylose. The key step involves a stereospecific substitution of a hydroxy group, without prior derivatization, in which the only byproduct is water. This opens up a novel benign route to iminosugar derivatives with diverse biological activities.

Published: February 2023

Abstract
Introduction Septoplasty and turbinoplasty are common surgical interventions used to relieve nasal obstructive symptoms. Since it is difficult to measure the degree of nasal blockage, current literature wonders about the frequent performance of these procedures.
Objective To evaluate the perceived change in the nasal obstruction and the quality of life (QoL) of patients that underwent a septoplasty along with a turbinoplasty by applying subjective scales, to describe the correlation between those scales, and to study the impact of clinical factors in the postoperative outcomes.
Methods Prospective observational study. The Nasal Obstruction Symptom Evaluation (NOSE), the Visual Analog Scale (VAS), and the Glasgow Benefit Inventory (GBI) were assessed. The paired sample Wilcoxon test was used to evaluate the difference between the pre- and postoperative surveys. The correlation coefficient between the subjective scales was calculated. A quantile regression was performed to evaluate the effect of surgery on the results adjusted for clinical and demographic variables.
Results A total of 115 patients were interviewed. Postoperative NOSE scores were 45 points lower (95% confidence interval [CI]: - 53.53–- 35.46; p < 0.001) in comparison with the NOSE preoperative scores. Obesity was the only statistically significant factor associated with worse outcomes. Additionally, we found a high correlation between the NOSE and VAS scores and a negative correlation between the GBI and postoperative VAS scores.
Conclusion Nasal septoplasty, when paired with a turbinoplasty, decreases nasal obstruction and improves QoL. Obesity was associated with worse results. There was a strong correlation between the NOSE and the VAS results and between the GBI and postoperative VAS results.

AbstractA group of thirteen catalysts of type [Ru(Cp/Cp*)(P–P)(MeCN)]PF6, bearing cooperative or noncooperative bidentate phosphine ligands, were evaluated for the catalytic acceptorless dehydrogenation of indoline. The systematic comparison revealed that the optimal cooperative catalyst structure included a Cp ancillary ligand, and an N,N-disubstituted P,P-disubstituted 1,5-diaza-3,7-diphosphacyclooctane ligand, denoted as (PR

2NPh
2 ligand exhibited about a twofold longer lifetime than a noncooperative analogue with (diphenylphosphino)ethane (dppe) as the supporting bisphosphine ligand. The cooperative catalyst effectively dehydrogenated a range of indoline substrates to give substituted indoles.
Concise Synthesis of the Hexasaccharide Repeating Unit of the Capsular Polysaccharide of Klebsiella K19 Strain
Authors: Misra Anup Kumar , Sahaji Samim , Shit Pradip 
Published: February 2023

AbstractA convergent [4+2] stereoselective block glycosylation strategy has been developed for the synthesis of the hexasaccharide repeating unit of the capsular polysaccharide of Klebsiella K19 strain in very good yield. The p-methoxybenzyl (PMB) group was used as a temporary alkyl protecting group, which was removed by tuning the glycosylation conditions. A thioglycoside was used as a glycosyl acceptor in an orthogonal glycosylation reaction. A late-stage TEMPO-mediated selective oxidation of a primary hydroxyl group into carboxylic acid allowed incorporation of the d-glucuronic acid moiety in the hexasaccharide. A combination of N-iodosuccinimide (NIS) and perchloric acid supported over silica (HClO4–SiO2) was used as a thiophilic promoter for the activation of thioglycosides. HClO4–SiO2 was also used as a solid acid activator for a glycosyl trichloroacetimidate derivative.

Published: February 2023

AbstractCapsuloligamentous injury of the first metatarsophalangeal (MTP) joint (eponymously called “turf toe”) mostly occurs in athletes and involves acute trauma, whereas tears of the lesser MTP joint plantar plate typically are an attritional-degenerative condition. This article reviews the anatomy, pathophysiology, mechanism and patterns of injury, grading and classification of injury, imaging appearances (pre- and postoperative), and management of first MTP joint capsuloligamentous injuries and lesser MTP joint plantar plate tears. These two distinct pathologies are discussed in separate sections.
Elastic, electronic, optical, and thermodynamic properties of M2SeC (M = Hf, Zr) under high pressure

Published: February 2023

The physical properties of the synthesized MAX phases M2SeC (M = Hf, Zr) have been investigated for the first time using the DFT method in the pressure range 0–25 GPa. The computed lattice parameters are consistent with the earlier findings at ambient pressure. The electronic band structure and energy dependent density of states reveal the metallic nature of the titled compounds. The metallic behavior of M2SeC (M = Hf, Zr) remains unchanged within the studied pressure range. Possible changes in the mechanical properties between Hf2SeC and Zr2SeC are revealed by analyzing the peaks in the density of states (DOS) for both compounds. Partial DOS is also considered under different pressures. The studied compounds remain mechanically stable up to 25 GPa. Both Hf2SeC and Zr2SeC are elastically anisotropic and brittle, but as the pressure increases up to 25 GPa, the brittleness of the materials decreases. At 5 and 10 GPa, however, both compounds exhibit a ductile behavior. The optical properties of Hf2SeC have been computed for the first time and compared with those of Zr2SeC. The investigated compounds are promising as solar heat reflectors due to their higher reflectivity in the low energy state. Different thermal properties, such as Debye temperature, melting temperature, and minimum thermal conductivity, have been explored within the studied pressure range to recognize their suitability for high-temperature applications. Both Hf2SeC and Zr2SeC have the potential to be used as coating materials for thermal barriers, although Hf2SeC is a better option.
Dynamic control of Fano-like interference in the graphene periodic structure

Published: February 2023

Abstract
We propose and investigate a graphene periodic subsurface structure consisting of a coplanar pair of graphene ring resonators and a graphene ribbon. The Fano-like interference can be actively regulated by the applied magnetic field, incident angle and Fermi energy. Since the excited charges of graphene monolayer have cyclotron properties in the external magnetic field, the transmittance and line-shape can be effectively controlled. At a certain frequency, different magnetic fields have different effects on the conductivity tensor of graphene, which affects the metallic properties of graphene, leading to changes in the transmittance. The Fano-like line-shape can be regulated by adjusting the incident angle to delay the phase between adjacent graphene sheets. In addition, the resonance frequency can be electrically regulated through Fermi energy. Finite element method is introduced to analyze the graphene periodic structure and the results are demonstrated by multimode interference coupled mode theory. The Faraday rotation angle exceeding 85° are observed in a small magnetic flux density B of about 0.5 T. Moreover, a plasma-optic switching with high ON/OFF ratio and large modulation depth (MD) is designed, whose ON/OFF ratio (η) and MD are 19.921 dB and 98.982%, respectively. Notably, combining the influence of magnetic flux density on transmittance and the modulation of resonance frequency by Fermi energy, optical switching can be implemented at any frequency within the frequency range studied. These results provide methods for active regulation of electromagnetic waves in the terahertz field and have potential applications in optical switching and integrated photonic circuit.

Abstract

Objective. Laser interstitial thermal therapy (LITT) is a minimally invasive procedure used to treat a lesion through light irradiation and consequent temperature increase. Magnetic resonance thermometry imaging (MRTI) provides a multidimensional measurement of the temperature inside the target, thus enabling accurate monitoring of the damaged zone during the procedure. In proton resonance frequency shift-based thermometry, artifacts in the images may strongly interfere with the estimated temperature maps. In our work, after noticing the formation of the dipolar-behavior artifact linkable to magnetic susceptibility changes during in vivo LITT, an investigation of susceptibility artifacts in tissue-mimicking phantoms was implemented. Approach. The artifact was characterized: (i) by measuring the area and total volume of error regions and their evolution during the treatment; and (ii) by comparison with temperature reference provided by three temperature sensing needles. Lastly, a strategy to avoid artifacts formation was devised by using the temperature-sensing needles to implement a temperature-controlled LITT. Main results. The artifact appearance was associated with gas bubble formation and with unwanted treatment effects producing magnetic susceptibility changes when 2 W laser power was set. The analysis of the artifact’s dimension demonstrated that in the sagittal plane the dipolar-shape artifact may consistently spread following the temperature trend until reaching a volume 8 times bigger than the ablated one. Also, the artifact shape is quite symmetric with respect to the laser tip. An absolute temperature error showing a negative Gaussian profile in the area of susceptibility artifact with values up to 64.4 °C was estimated. Conversely, a maximum error of 2.8 °C is measured in the area not-affected by artifacts and far from the applicator tip. Finally, by regulating laser power, susceptibility artifacts formation was avoided, and appreciable thermal damage was induced. Significance. These findings may help in improving the MRTI-based guidance of thermal therapies.
The roles of Kerr nonlinearity in a bosonic quantum neural network

Published: February 2023

Abstract
The emerging technology of quantum neural networks (QNNs) offers a quantum advantage over classical artificial neural networks (ANNs) in terms of speed or efficiency of information processing tasks. It is well established that nonlinear mapping between input and output is an indispensable feature of classical ANNs, while in a QNN the roles of nonlinearity are not yet fully understood. As one tends to think of QNNs as physical systems, it is natural to think of nonlinear mapping originating from a physical nonlinearity of the system, such as Kerr nonlinearity. Here we investigate the effect of Kerr nonlinearity on a bosonic QNN in the context of both classical (simulating an XOR gate) and quantum (generating Schrödinger cat states) tasks. Aside offering a mechanism of nonlinear input-output mapping, Kerr nonlinearity reduces the effect of noise or losses, which are particularly important to consider in the quantum setting. We note that nonlinear mapping may also be introduced through a nonlinear input-output encoding rather than a physical nonlinearity: for example, an output intensity is already a nonlinear function of input amplitude. While in such cases Kerr nonlinearity is not strictly necessary, it still increases the performance in the face of noise or losses.

Published: February 2023

Abstract
We propose a scheme for constructing a phase plate for use in an ultrafast Zernike-type phase contrast electron microscope, based on the interaction of the electron beam with a strongly focused, high-power femtosecond laser pulse and a pulsed electron beam. Analytical expressions for the phase shift using the time-averaged ponderomotive potential and a paraxial approximation for the focused laser beam are presented, as well as more rigorous quasiclassical simulations based on the quantum phase integral along classical, relativistic electron trajectories in an accurate, non-paraxial description of the laser beam. The results are shown to agree well unless the laser beam is focused to a waist size below a wavelength. For realistic (off-the-shelf) laser parameters the optimum phase shift of -π/2 is shown to be achievable. When combined with RF-cavity based electron chopping and compression techniques to produce electron pulses, a femtosecond regime pulsed phase contrast microscope can be constructed. The feasibility and robustness of the scheme are further investigated using the simulations, leading to motivated choices for design parameters such as wavelength, focus size and polarization.
A novel chaotic DICOM image encryption algorithm based on pseudo-random polyline and rapid diffusion-scrambling
Authors: Zhang Ziying , Teng Lin 
Published: February 2023

Abstract
This paper proposes a novel chaotic DICOM image encryption algorithm based on pseudo-random polyline and rapid diffusion-scrambling. This paper proposes to preprocess the image twice in the encryption process to ensure that any type of image can be encrypted, including images with negative pixel values, which increases the practicability of the algorithm. Two pseudo-random polylines are generated to segment the image during the encryption process. The pseudo-random polylines are generated from the information of the plaintext image, which ensures that each image produces different pseudo-random polylines and increases the security of the algorithm. In the encryption process, rapid diffusion-scrambling is used to avoid the waste of extra space. And piecewise diffusion and non-adjacent matrix reading are adopted to make the encryption more unpredictable. The scheme is analyzed from the performance indicators such as pixel correlation and key space, and the results demonstrated strong security and performance of the algorithm.
