Published: March 2023

AbstractLiquid crystals are appealing in pharmaceutical and cosmetic fields due to their unique structures that combine the properties of both liquid and solid states. Forming an emulsion into liquid crystals can be affected by a number of factors, including the emulsion composition and temperature. Changing the types and concentrations of surfactants could be another factor that affects liquid crystals. Currently, most liquid crystal research focuses on the nanostructure of liquid crystal systems without evaluating the efficacy of liquid crystals clinically. In this study, liquid crystalline emulsions made from camellia seed oil with four different surfactants (Olivem 1000, Polyaquol-2W, Nikkomulese LC, and Lecinol S-10 with Tween 80) were created. The liquid crystal emulsions were formulated in the form of oil-in-water (o/w) emulsions with Camellia oleifera seed oil serving as the main ingredient in the oil phase (10% w/w). All formulations exhibited liquid crystal characteristics with lamellar structures as determined by the polarized light microscopy and small-angle X-ray scattering with supporting data of the nanostructure from wide-angle X-ray scattering and differential scanning calorimetry (DSC). They all showed good stability under normal (room temperature) and accelerated conditions (4 °C and 40 °C) in long-term storage (6 months). Using the reconstructed human epidermis as a skin model, all formulations did not cause skin irritation. In the clinical trial, all formulations were able to reduce transepidermal water loss (TEWL) and increase skin hydration immediately after application. This lasted at least 10 h. All formulations showed distinct Maltese crosses under the polarized light microscope with a positive result for liquid crystals in wide angle X-ray scattering (WAXS) and small angle X-ray scattering (SAXS) methods. Moreover, among all formulations tested, Formulation D, which contained Lecinol S-10 and Tween 80 as emulsifiers, showed the most robust interaction between the surfactant and water molecules in the lamellar structure under DSC. The formulation was stable in long-term normal and accelerated conditions. Above all, Formulation D, which was formulated with Lecinol S-10 with Tween 80, had the best clinical result, was nonirritating to the skin, and can be used as a cream base in the pharmaceutical and cosmeceutical sectors.

AbstractComposition and floristic diversity of ecosystems subject to overexploitation, such as tropical deciduous forests where copal resin (Bursera bipinnata, Bursera copallifera) is extracted, are of great importance for understanding the ecological functioning of these ecosystems. This study analyzed the species composition and diversity in a natural population subject to copal extraction in San Juan Raboso Izúcar de Matamoros, Puebla, Mexico. A total of 54 sampling units were established, and the number of individuals and crown diameter for each tree species were recorded. For shrubs, succulents, acaulescent rosetophytes and climbers, the number of individuals and the area of cover were quantified. Based on the parameters of abundance, frequency, and relative dominance, the importance value index (IVI) was calculated. Diversity was evaluated using the Shannon index $$(H {^{\prime}})$$

Published: March 2023

AbstractWe present a novel scheme to obtain robust, narrowband, and tunable THz emission using a nano-dimensional overdense plasma target, irradiated by two counter-propagating detuned laser pulses. So far, no narrowband THz sources with a field strength of GV/m-level have been reported from laser-solid interaction (mostly half-or single-cycle THz pulses with only broadband frequency spectrum). From two- and three-dimensional particle-in-cell simulations, we find that the strong plasma current generated by the beat ponderomotive force in the colliding region, produces beat-frequency radiation in the THz range. Here we report intense THz pulses $$(f\simeq 30 \;$$

Prespecifiable fixed‐time control for uncertain nonlinear system with input quantization
Authors: Gao Yang , Ma Jiali , Chen Qingwei , Wu Yifei , Qian Chen 
Published: March 2023

AbstractThis paper focuses on the global prespecifiable fixed‐time control problem of uncertain strict‐feedback nonlinear system with input quantization. In contrast to the existing fixed‐time control results, the signs of the control gains can be unknown in our paper. Unlike the traditional fixed‐time control schemes, some exponential functions are added into the virtual controllers to accelerate the convergence rate. Besides, some dynamic switching functions are also introduced to compensate the unknown control signs. Based on the novel regulate law, the switching functions can be regulated online to ensure the fixed‐time stability for the considered system. Furthermore, the settling time can be easily adjusted by selecting the controller parameters. Simulation results are provided to illustrate the effectiveness of the proposed control scheme.
Comparative analysis of antenna isolation characteristic with & without self‐interference reduction techniques towards in‐band full‐duplex operation
Authors: Yalcinkaya Merve Tascioglu , Sen Padmanava , Fettweis Gerhard 
Published: March 2023

AbstractThe advancement of communication and radar systems has triggered the demand for in‐band full‐duplex (IBFD) operation. IBFD is regarded as one of the most outstanding technologies in terms of its ability to improve spectral efficiency and data rate. IBFD operation has the potential not only to enable communication or radar systems separately, but to help realising radar sensing and communication at the same time, known as Joint Communication and Sensing (JC&S) technology. In realisation of IBFD and JC&S systems, self‐interference (SI) is the key challenge for antenna designers. In this article, a comprehensive survey on SI reduction techniques in the antenna domain is provided and the advantages and disadvantages of each technique are studied. SI reduction techniques have been proposed separately but an elaborated review of relevant techniques with a comparative study has not been presented yet. For the first time, a systematic comparative study of different SI reduction techniques is graphically presented to cover a comparison based on isolation, gain, and impedance bandwidth in terms of before and after SI reduction techniques. Moreover, this study also explores how antenna isolation characteristics vary with respect to the thickness and the permittivity of the substrate without any SI reduction technique.

Published: March 2023

AbstractWith the rapid development of photovoltaic (PV) power generation, state recognition of PV arrays is of great significance to its intelligent operation and maintenance. But the random fluctuation of PV power output leads to the obvious uncertainty for performance calculation of PV arrays; this paper proposes an evaluation method of PV arrays. Firstly, the performance calculation method and its distribution model were proposed by the kernel density estimation (KDE) method. Secondly, the probability density distribution (PDD) of different indicators was analyzed to determine the suitable observation indicator so as to introduce the stability indicator, from which the benchmark array was selected. Finally, the state recognition of PV arrays was achieved. The main conclusions and innovations of this paper are the stability evaluation method of PV arrays based on the non‐parameter estimation method and the effective operating state recognition method for PV arrays. The proposed method was proven to be more reliable by comparing it to the power generation ranking method (PGRM). The effectiveness was verified by comparing the statistical and real‐time distribution of the performance ratio, and the excess rate of different confidence levels and Euclidean distance were introduced to demonstrate the accuracy of the proposed state recognition method.
« Femmes, écologie et engagements politiques du Sud au Nord » : actualité de l’écoféminisme
Authors: Larrère Catherine 
Published: March 2023

Que nous apprennent les luttes écologiques dans lesquelles s’engagent les femmes, du Sud au Nord ? Tel était le thème du colloque organisé par l’Université Paris 1 Panthéon-Sorbonne (Institut des sciences juridique et philosophique de la Sorbonne [ISJPS]) et l’Université de Chicago à Paris, les 4 et 5 juin 2021. Le fil conducteur fut celui de la lutte contre l’extractivisme (extraction minière, forages pétroliers et gaziers, mais aussi déforestation, plantations arbustives ou agricoles destinées à l’exportation et pêcheries industrielles), dans un débat qui a abordé les questions de spiritualité, puis en est venu à la justice environnementale, avant de parler du care, en un retour réflexif sur les questions soulevées par ces luttes qui ne se réclament pas toujours de l’écoféminisme, mais permettent d’en éclairer les enjeux : ceux de la domination croisée des femmes et de la nature. Si ce type de mouvement s’expose à l’accusation d’essentialisation ou de naturalisation, les discussions ont fait ressortir la pluralité des références à la nature ainsi que celle des formes d’émancipation.

Orbitocranial Penetration of Ball Bearing Gun Trauma: A Prospective Human Cadaveric Study
Authors: Oh Angela J. , Roelofs Kelsey A. , Karlin Justin N. , Rootman Daniel B. 
Published: March 2023

Abstract
Objective We completed a prospective human cadaveric study to determine the ability of a ball bearing (BB) pellet to penetrate the orbit and/or surrounding structures.
Methods A single trained sergeant officer discharged an alloy steel air rifle to eight cadaver orbits from four adult human cadaver heads. Five BB pellets each were aimed at three locations (caruncle, upper eyelid, or lower eyelid) at 10 cm and 1 m, and then less specifically, at the orbital region for 3- and 5-m distances. Computed tomography (CT) of the cadaver heads was performed. Final locations of BB pellets are divided into three categories: intracranial, surrounding orbital structures including the pterygopalatine fossa and infratemporal fossa, and orbit.
Results Of 40 BB pellets, 37 penetrated soft tissue and were visualized on CT: 19 (51%) rested in the intracranial space, 17 (46%) in surrounding orbital structures, and 1 (3%) within the orbit. The deepest position of a pellet was in the parietal lobe, and most superficial location anterior to the frontal bone. Pellets discharged from 1 m were more likely to rest in the intracranial space compared with those from 10 cm (p < 0.001), 3 m (p = 0.011), and 5 m (p = 0.004). The distance of discharge was associated with final pellet location (p = 0.001).
Conclusion BB guns should be considered dangerous and potentially deadly when aimed at the orbit. Although the thick calvarium can protect the intracranial space from BB penetration, the orbit may be a vulnerable entry point with relatively low resistance, allowing penetration of the intracranial and periorbital spaces.

Published: March 2023

Abstract
Background We compare the radiologic and clinical results between the short-segment fixation and the long-segment fixation in the thoracolumbar junction distraction fractures.
Methods We retrospectively reviewed the prospectively recorded data of patients who underwent posterior approach and pedicle fixation treatment for thoracolumbar distraction fracture (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association AO/OTA 5-B) with a minimum of 2 years of follow-up. A total of 31 patients were operated on; they were divided into two groups: (1) patients treated with short-level fixation (SLF; one level above and below the fracture level) and (2) patients treated with long-level fixation (LLF; two levels above and below the fracture level). The clinical outcomes were evaluated with the neurologic status, operation time, and time to surgery. The functional outcomes were evaluated with the Oswestry Disability Index (ODI) questionnaire and visual analog scale (VAS) at the final follow-up. Radiologic outcomes were measured with the local kyphosis angle, anterior body height, posterior body height, and sagittal index of the fractured vertebra.
Results SLF was performed in 15 patients and LLF was performed in 16 patients. The average follow-up period was 30.13 ± 11.3 months for the SLF group and 35.3 ± 17.2 months for group 2 (p = 0.329). The two groups were similar in regard to age, gender, follow-up period, fracture level, fracture type, and pre- and postoperative neurologic status. The operating time was significantly shorter in the SLF group than in the LLF group. There were no significant differences between the groups in all radiologic parameters, ODI score, and VAS.
Conclusion SLF was associated with a shorter operation time and allowed the preservation of two or more segments of vertebral motion.

AbstractThe objective is to assess impact of fluid removal on improvement in organ function in children who received continuous renal replacement therapy (CRRT) for management of acute kidney injury and/or fluid overload (FO). A retrospective review of eligible patients admitted to a tertiary level intensive care unit over a 3-year period was performed. Improvement in nonrenal organ function, the primary outcome, was defined as decrease in nonrenal component of Pediatric Logistic Organ Dysfunction (PELOD) score on day 3 of CRRT. The cohort was categorized into Group 1 (improvement) and Group 2 (no improvement or worsening) in nonrenal PELOD score. Multivariable logistic regression analysis was performed to identify independent predictors. A higher PELOD score at CRRT initiation (odds ratio [OR]: 1.11, 95% confidence interval [CI]: 1.05, 1.18, p < 0.001), belonging to infant-age group (OR: 4.53, 95% CI: 4.40, 5.13, p = 0.02) and greater fluid removal during initial 3 days of CRRT (OR: 1.05, 95% CI: 1.01, 1.10, p = 0.01) were associated with an improvement in nonrenal PELOD score at day 3 of CRRT. FO at CRRT initiation (OR: 0.66, 95% CI: 0.46, 0.93, p = 0.02) and having an underlying oncologic diagnosis (OR: 0.28, 95% CI: 0.09, 0.85, p = 0.03) were associated with worsening of nonrenal PELOD score at day 3 of CRRT. Careful consideration of certain modifiable patient and/or fluid removal kinetic factors may have an impact on outcomes.
Price fairness: square equity and mean pricing
Authors: Radic Dubravko 
Published: March 2023

AbstractPrices have a leverage effect on firm profits. Prices, however, have also an impact on customer’s perceived price fairness and thus indirectly on firm’s bottom line. A growing body of literature shows this. Papers on the level of the fair price, however, are rather scarce. Based on different concepts of justice, two levels of fair prices are proposed: square equity and mean prices. I run an experiment which shows that both are considered fairer than cost-based or value-based prices. The results can be used to assess fairness implications of prices ex ante and hence complement traditional pricing approaches.

Published: March 2023

In precision micromanipulation tasks, operation accuracy and anti-disturbance performance of micromanipulators are critical. This paper presents anti-disturbance control for a piezo-driven micromanipulator with a non-minimum phase. The micromanipulator is constructed by mounting a flexible manipulator on a parallel positioning stage. The micromotion and dynamic behavior of the micromanipulator are analyzed. Then, an anti-disturbance control strategy combining H-infinity feedback control and disturbance observer-based control for a non-minimum phase is designed to reduce disturbances and ensure control accuracy. Finally, the experimental measurement and control system is built. The observed phenomena show that sinusoidal disturbances are almost eliminated and the overshoot of step disturbances is significantly reduced. In addition, the time for suppressing the step disturbance is shortened from 0.9 to 0.3 s. Experiments verify the viability of the anti-disturbance control strategy.
Design of a metamaterial chipless RFID sensor tag for high temperature
Authors: Wang Bo , Li Youwei , Gu Tingting 
Published: March 2023

A high temperature sensor based on a metamaterial is proposed as a chipless radio frequency identification sensor tag that can measure temperature wirelessly. The metamaterial, based on a double circular split ring resonator (SRR), is highly frequency selective and has negative permittivity. The double circular SRR is fabricated on the alumina ceramic substrate, which acted as the temperature sensing material. The permittivity of the material varies with the temperature parameter, resulting in a shift of backscattered resonant frequency of the sensor tag. Simulations verify the feasibility of this sensor tag in the microwave band under electromagnetic stimuli. When the temperature increases from 200 to 1000 °C, the resonant frequency monotone decreases from 6.64 to 6.26 GHz with an average sensitivity of 0.475 MHz/°C. The sensor tag has features such as high temperature, being wireless, passive, of comparatively low-cost, and miniature, with diversified application potential, allowing it to compete with other sophisticated temperature devices in terms of performance.
Parameter error analysis of dual-channel Mach–Zehnder interferometer for molecular Doppler wind lidar
Authors: Tan Linqiu , Guo Quanmin , Wang Qian , Sun Bin 
Published: March 2023

Based on the atmospheric molecular Doppler wind lidar system using dual-channel Mach–Zehnder interferometer (DMZI) double-edge detection, two important DMZI parameters, such as optical path difference and beam splitter transmittance, are analyzed. Furthermore, the changes in DMZI transmission response, wind speed sensitivity, and wind speed measurement errors of the lidar system caused by the errors of these two parameters are simulated. The ratio of the difference between the system measurement error caused by the non-optimal parameter and the optimal parameter to the system measurement error at the optimal parameter is defined as an error proportion factor, which can be used to quantitatively describe the variation of wind speed measurement error caused by the parameter errors. Numerical simulation shows that under the assumption that the horizontal wind speed is 20 m/s and the vertical detection height is 15 km, if this error proportion factor needs to be controlled to less than 1%, the difference δ_Δl0 between the actual and the optimal optical path difference should be controlled in the range of 0 ≤ δ_Δl0 &lt; 3.16 mm. Similarly, if other parameters are optimal, the beam splitter transmittance of DMZI should be controlled in the range of 0.5 ± 0.0407, and the error proportion factor can be less than 1%. The results of this study not only provide theoretical guidance for the parameter selection of DMZI but also provide research ideas and methods for the error analysis of DMZI molecular Doppler lidar based on double-edge detection.
