Donor-Site Satisfaction of DIEP and Latissimus Dorsi Flaps—A Comparative Cohort Study
Authors: Löfstrand Jonas , Paganini Anna , Lidén Mattias , Hansson Emma 
Published: November 2022

Abstract
Background Understanding of donor-site morbidity and satisfaction after breast reconstruction is limited. There are few previous studies comparing satisfaction with different donor sites in breast reconstruction. This study aimed to examine the long-term patient-reported satisfaction with the donor site of latissimus dorsi (LD) flaps in comparison to the deep inferior epigastric artery perforator (DIEP) flaps. Further, a systematic review of previously published studies was conducted.
Methods In this retrospective cross-sectional study, all women who underwent breast reconstructions with either LD or DIEP flap following mastectomy and radiotherapy between 2007 and 2017 were included; patient-reported satisfaction was assessed using the BREAST-Q reconstruction module. For the systematic review, studies examining patient-reported abdominal satisfaction and well-being, and meeting the PICO (Population, Intervention, Comparison, and Outcome) criteria were included.
Results Eligible and responding participants were divided into the LD (n = 135 patients) and DIEP (n = 118 patients) flap groups. Impairment due to muscular weakness of the donor site was more common in the LD group than that of the DIEP group. Bulging was common in the DIEP group and increased over time. Regarding the esthetic appearance of the donor site, the patients in the DIEP group were less satisfied than the LD group. The systematic review showed that most of the patients were dissatisfied with their abdomen after the operation.
Conclusion Patients who have undergone DIEP flap for breast reconstruction are less satisfied with the donor-site esthetics than those who have undergone LD flap. Patient-reported abdominal bulging was common in the DIEP group and the number seemed to increase over time. Most patients were not satisfied with their abdominal scarring postoperatively, as per the systematic review. These results may indicate a need for more nuanced preoperative patient information, as well as improvements in the surgical management of the donor site, for DIEP flap reconstructions.

Authors: Saranto Kaija , Koponen Samuli , Vehko Tuulikki , Kivekäs Eija 
Published: November 2022

Abstract
Background Current information systems do not effectively support nurse managers' duties, such as reporting, resource management, and assessing clinical performance. Few performance management information systems are available and features in many are scattered.
Objectives The purpose of the study was to determine nurse managers' opinions of information system support for performance management.
Methods An online questionnaire was used to collect data from nurse managers (n = 419). Pearson's correlation coefficients and linear regression were used to examine the relationships between variables, which were nurse managers' ability to manage resources, to report and evaluate productivity, and to assess nursing performance and clinical procedures.
Results More than half of the managers used performance management systems daily. Managers (60%) felt that they can use information systems to follow the use of physical resources, and in general (63%), they felt that it is easy to perform searches with the systems used for following up activity. Nurse managers' ability to manage resources, to report productivity, and to assess nursing care performance were correlated significantly with each other.
Conclusion Currently, managers have to collect data from various systems for management purposes, as system integration does not support performance data collection. The availability of continuous in-service training had a positive effect on information system use.
Fused λ5-Phosphinines: Design, Syntheses, and Properties
Authors: Hayashi Minoru , Ohta Hidetoshi , Fujimoto Shion 
Published: November 2022

AbstractSynthesis of several heterocycle-fused λ5-phosphinines through intramolecular cyclization is described. The incorporation of a heteroatom affected their photophysical properties through perturbation of the LUMO level, which is in good contrast to the HOMO-based tuning by the C-4 substituent. The C-3-substituent-based property tuning provides a new guide to designing phosphinine-based fluorophores.
Powered versus Cold Instruments in Rhinoplasty: A Perspective
Authors: Winkler Andrew A. 
Published: November 2022

AbstractRhinoplasty surgeons must continually strive to refine and improve their results. Improvement may be borne out of new surgical techniques, alternative perioperative medicines, or through the application of new technologies. One technology that has recently gained popularity are piezoelectric osteotomes (POs). These instruments offer a powered alternative to the traditional chisel osteotome. This article provides a history of these two modalities, reviews the most recent data surrounding piezoelectric osteotomy, and provides a framework to compare the pros and cons of each osteotomy option.

Published: November 2022

A novel Motional Stark Effect spectroscopy system has been designed for application at the DIII-D tokamak. The system is optimized for studies of the poloidal and toroidal magnetic field in the plasma pedestal region with frame rates of up to 10 kHz. Light from an existing high-photon-throughput collection lens is analyzed using four single-channel f/2.8 Czerny–Turner spectrometers that use custom-made lens systems instead of mirrors. Each spectrometer has two separate outgoing legs and is operated in a positive grating order, which allows for simultaneous observations of D-alpha and D-beta spectra. Forward modeling using the code FIDASIM shows a radial resolution of the system close to 0.6 cm and sufficiently good spectral resolution when masking the high throughput light collection lens in the horizontal direction to avoid overly strong Doppler broadening of beam emission lines. Moreover, a detailed sensitivity study considering realistic levels of readout and photon noise shows that the poloidal and toroidal magnetic field strengths can be inferred with an uncertainty of less than 1%, which will allow the inference of changes of the plasma current during transient events.

A Fast Visible Imaging Diagnostic (FVID) system, measuring the visible light emission spectrum (400–1000 nm) from tokamak plasma, has been installed on the Aditya-U tokamak to monitor the two-dimensional dynamics of the poloidal cross section of the plasma. In this work, we present the design and installation of the FVID system on the Aditya-U tokamak. The evolution of plasma and plasma–wall interactions is described. The signature of the runaway electron beam in visible imaging and its correlation with other diagnostics is presented. The estimation of the electron cyclotron resonance layer position during pre-ionization is also discussed in this work.
A Fundamental Equation of State for the Calculation of Thermodynamic Properties ofn-Octane
Authors: Beckmüller R. , Span R. , Lemmon E. W. , Thol M. 
Published: November 2022

An empirical equation of state in terms of the Helmholtz energy is presented for n-octane. It is valid from the triple-point temperature 216.37 K to 650 K with a maximum pressure of 1000 MPa and allows for the calculation of all thermodynamic properties in the vapor and liquid phase, in the supercritical region, and in equilibrium states. In the homogeneous liquid phase, the uncertainty in density is 0.03% at atmospheric pressure. For pressures up to 200 MPa and temperatures between 270 and 440 K, density is described with an uncertainty of 0.1%. Outside this region, the uncertainty in the liquid phase increases to 0.5%. Densities in the vapor phase are estimated to be accurate within 0.5%. The uncertainty in vapor pressure depends on the temperature range and varies from 0.02% to 0.4%. Speed of sound in the liquid phase at temperatures below 500 K is described with an uncertainty of 0.1% or less. The isobaric heat capacity in the liquid phase can be calculated with an uncertainty of 0.1% and in the gas phase with 0.2%. A reasonable physical behavior of the equation of state was ensured by the analysis of numerous thermodynamic properties.

Published: November 2022

Liquid water is one of the most studied substances, yet many of its properties are difficult to rationalize. The uniqueness of water is rooted in the dynamic network of hydrogen-bonded molecules with relaxation time constants of about one picosecond. Terahertz fields oscillate on a picosecond timescale and are inherently suited to study water. Recent advances in non-linear terahertz spectroscopy have revealed large signals from water, which have been interpreted with different, sometimes competing, theoretical models. Here, we show that the non-linear transmission of liquid water at ∼1 THz is equal at 21 and 4 °C, thus suggesting that the most appropriate microscopic models should depend weakly on temperature. Among the different mechanisms proposed to date, the resonant reorientation of hydrogen-bonded water molecules might be the most appropriate to describe all of the currently available experimental results.
The emergence and history oftuteo,voseoandustedeo
Authors: Lara Bermejo Víctor 
Published: November 2022

AbstractThe second person pronouns in Spanish have exhibited numerous variants along its history, not only regarding its stressed forms, but also the agreement that emerges in the inflecting elements that anchor these stressed pronouns. Despite the quantity of studies carried out aboutvoseo,tuteoandustedeo, none of them has argued what grammatical reasons underlie for so much variation, since they have focused on pragmatic and sociolinguistic patterns without going any further than a mere description. In this article, I aim to account for the linguistic features that have triggered all variants and person disagreements, for every case has undergone the same grammatical process.

Published: November 2022

Abstract
The charge accumulation phenomenon at the gas–solid interface under the co-action of DC electric field and temperature gradient is of great significance, but its long-time evolution characteristics are still unclear. In this work, the accumulation and dissipation characteristics of the surface charge on the epoxy-SF6 interface within 216 h were obtained, indicating that, (a) the normal surface electric field is increased by the temperature gradient along the gas–solid interface, which results in a prominent increase in the surface charge density; (b) there are different evolution processes of surface charge in high and low temperature regions under the co-action of DC-temperature gradient, and the increase of the charge trap density caused by the degradation of solid material is considered to be an important reason for the charge evolution; (c) the total charge dissipation ratio within 600 s decreases with the increase of charging time in DC electric field, and the surface charge dissipates mainly to the gas side of the interface; (d) the large amount of charge accumulated at the interface distorts the surface electric field at the triple junction points. The total electric field strength at the low-temperature tri-junction point increases by 35.5%, while the direction of the tangential field at the high-temperature tri-junction point reverses during the long-time co-action of the DC-temperature gradient. The results of this work may be helpful to understand the long-time charge evolution characteristics of the gas–solid interface under the DC-temperature gradient and to reveal the failure mechanism of the gas–solid interface.
Improved Smith–Purcell free-electron laser based on quasi-bound states in the continuum
Authors: Chen Zhaofu , Mao Leilei , Jin Mengmeng , Shi Xin 
Published: November 2022

Abstract
In this article, a method to enable efficient emission of coherent radiation by using an intense electron beam coupled with a quasi-bound state in the continuum (quasi-BIC) is investigated. We present an analytical solution providing an intuitive round-trip phase condition to explain the origin of quasi-BICs of dielectric gratings. Numerical study of the beam–wave interaction shows that the electrons can be bunched by the synchronous space harmonic enhanced by the quasi-BIC, resulting in self-excited coherent oscillation and consequently efficient Smith–Purcell radiation. This work presents an interesting solution for coherent radiation sources, and may find application in communications and physics.

Published: November 2022

Abstract
Gliding arc is a promising plasma technology for water activation due to its high energy efficiency for producing reactive nitrogen species (RNS), which is believed as the key agent for the sustained bactericidal effect of plasma-activated water (PAW). Nitric oxide (NO) is the major product of gliding arc and also widely exists in PAW, but the production mechanism of aqueous NO and its role in sterilization have been little investigated before. In this paper, NO-rich plasma effluent gas is produced by gliding arc discharge and introduced into water to produce PAW. The concentrations of gaseous and aqueous reactive species are detected, which decrease with the increasing air flowrate of the gliding arc. To clarify the contribution of plasma-induced RNS on water activation, the NO + air mixed gas is used to simulate the plasma effluent gas, and the results show that the two gases have similar gaseous composition and aqueous NO yield. Compared with the NO + Ar mixed gas with the same NO proportion, the NO + air mixed gas produces much more aqueous NO, implying that the presence of O2 significantly enhances the production of aqueous NO. The sterilization experiments demonstrate the key role of aqueous NO in sterilization, but an acidic environment is necessary for aqueous NO to achieve a potent bactericidal effect.
Magnetic forces in paramagnetic fluids
Authors: Butcher Tim A , Coey J M D 
Published: November 2022

Abstract
An overview of the effect of a magnetic field gradient on fluids with linear magnetic susceptibilities is given. It is shown that two commonly encountered expressions, the magnetic field gradient force and the concentration gradient force for paramagnetic species in solution are equivalent for incompressible fluids. The magnetic field gradient and concentration gradient forces are approximations of the Kelvin force and Korteweg–Helmholtz force densities, respectively. The criterion for the appearance of magnetically induced convection is derived. Experimental work in which magnetically induced convection plays a role is reviewed.
Field-induced boson insulating states in a 2D superconducting electron gas with strong spin–orbit scatterings
Authors: Maniv Tsofar , Zhuravlev Vladimir 
Published: November 2022

Abstract
The phenomenon of field-induced superconductor-to-insulator transitions observed experimentally in electron-doped SrTiO3/LaAlO3 interfaces, analyzed recently by menas of 2D superconducting fluctuations theory, is revisited with new insights associating it with the appearnace at low temperatures of field-induced boson insulating states. Within the framework of the time-dependent Ginzburg–Landau functional approach, we pinpoint the origin of these states in field-induced extreme softening of fluctuation modes over a large region in momentum space, upon diminishing temperature, which drives Cooper-pair fluctuations to condense into mesoscopic puddles in real space. Dynamical quantum tunneling of Cooper-pair fluctuations out of these puddles, introduced within a phenomenological approach, which break into mobile single-electron states, contains the high-field resistance onset predicted by the exclusive boson theory.
Application of IPSO-MCKD-IVMD-CAF in the compound fault diagnosis of rolling bearing
Authors: Zhou Jun , Wu Shi-Shuai , Liu Tao , Wu Xing 
Published: November 2022

Abstract
The vibration signals of rolling bearings are mixed with a variety of noises and a variety of faults which are coupled to each other, and which make the fault frequencies interfere with each other. This in turn leads to difficulty of accurate extraction of the features of composite faults. Therefore, it is necessary not only to suppress the noise of vibration signals but also to separate and extract the features of compound faults. A compound fault feature extraction method based on improved particle swarm optimization (IPSO) algorithm optimized maximum correlation kurtosis deconvolution (MCKD), improved variational mode decomposition (IVMD) and cyclic autocorrelation function (CAF), named IPSO-MCKD-IVMD-CAF is proposed. Firstly, the parameters of MCKD are selected adaptively by the IPSO, and the original signal is pre-processed by the parameterized MCKD. Secondly, the IVMD is utilized to decompose the signal, several intrinsic mode functions (IMFs) are obtained, the kurtosis and correlation coefficients of each IMF component are calculated. Finally, appropriate IMF components are selected by kurtosis and correlation coefficient to be superimposed into the reconstructed signals, and the reconstructed signals are analyzed by CAF. The proposed method has been successfully applied in simulation and measured vibration signal analysis, and the features of compound faults can be separated and extracted with high accuracy. The IPSO algorithm shortens the optimization time, and the IVMD solves the parameter selection problem. The analysis results of simulation case and measured data show the advantages of the proposed method IPSO-MCKD-IVMD-CAF. Compared to existing methods, the proposed method not only increases the accuracy of compound fault feature extraction, but also has a very good performance on the separation and extraction of compound fault features. More importantly, the improved algorithm reduces the computational complexity.
Colloidal synthesis of monodisperse trimetallic Pt–Fe–Ni nanocrystals and their enhanced electrochemical performances
Authors: Li Can , Pan Jinfong , Zhang Lihua , Fang Jiye 
Published: November 2022

Abstract
Among the multi-metallic nanocatalysts, Pt-based alloy nanocrystals (NCs) have demonstrated promising performance in fuel cells and water electrolyzers. Herein, we demonstrate a facile colloidal synthesis of monodisperse trimetallic Pt–Fe–Ni alloy NCs through a co-reduction of metal precursors. The as-synthesized ternary NCs exhibit superior mass and specific activities toward oxygen reduction reaction (ORR), which are ∼2.8 and 5.6 times as high as those of the benchmark Pt/C catalyst, respectively. The ORR activity of the carbon-supported Pt–Fe–Ni nanocatalyst is persistently retained after the durability test. Owing to the incorporation of Fe and Ni atoms into the Pt lattice, the as-prepared trimetallic Pt-alloy electrocatalyst also manifestly enhances the electrochemical activity and durability toward the oxygen evolution reaction with a reduced overpotential when compared with that of the benchmark Pt/C (△η = 0.20 V, at 10 mA cm−2). This synthetic strategy paves the way for improving the reactivity for a broad range of electrocatalytic applications.

Published: November 2022

Abstract
The suspended metallic nanostructures with tiny gaps have certain advantages in surface-enhanced Raman scattering (SERS) due to the coaction of the tiny metallic nanogaps and the substrate-decoupled electromagnetism resonant modes. In this study, we used the lithographic HSQ/PMMA electron-beam bilayer resist exposure combined with a deposition-induced nanogap-narrowing process to define elevated suspended metallic nanodimers with tiny gaps for surface-enhanced Raman spectroscopy detection. By adjusting the deposited metal thickness, the metallic dimers with sub-10 nm gaps can be reliably obtained. These dimers with tunable nanogaps successfully served as excellent SERS substrates, exhibiting remarkable high-sensitivity detection ability for crystal violet molecules. Systematic experiments and simulations were conducted to explain the origin of the improved SERS performance. The results showed that the 3D elevated suspended metallic dimers could achieve a higher SERS enhancement factor than the metallic dimers on HSQ pillars and a common Si substrate, demonstrating that this kind of suspended metallic dimer is a promising route for high-sensitive SERS detection and other plasmonic applications.

Abstract
Manipulating light at the sub-wavelength level is a crucial feature of surface plasmon resonance (SPR) properties for a wide range of nanostructures. Noble metals like Au and Ag are most commonly used as SPR materials. Significant attention is being devoted to identify and develop non-noble metal plasmonic materials whose optical properties can be reconfigured for plasmonic response by structural phase changes. Chromium (Cr) which supports plasmon resonance, is a transition metal with shiny finished, highly non-corrosive, and bio-compatible alloys, making it an alternative plasmonic material. We have synthesized Cr micro-rods from a bi-layer of Cr/Au thin films, which evolves from face centered cubic to hexagonal close packed (HCP) phase by thermal activation in a forming gas ambient. We employed optical absorption spectroscopy and cathodoluminescence (CL) imaging spectroscopy to observe the plasmonic modes from the Cr micro-rod. The origin of three emission bands that spread over the UV–Vis-IR energy range is established theoretically by considering the critical points of the second-order derivative of the macroscopic dielectric function obtained from density functional theory (DFT) matches with interband/intraband transition of electrons observed in density of states versus energy graph. The experimentally observed CL emission peaks closely match the s–d and d–d band transition obtained from DFT calculations. Our findings on plasmonic modes in Cr(HCP) phase can expand the range of plasmonic material beyond noble metal with tunable plasmonic emissions for plasmonic-based optical technology.
