Evolution process and failure mechanism of a large expressway roadside landslide
Authors: Zhang Jian , Zhang Shihua , Ding Yong , Zhu David Z. 
Published: March 2023

AbstractSite investigation, deformation monitoring, laboratory test, and theoretical calculations were used to analyze the evolution details of a large expressway roadside landslide during the start-up sliding process. The monitoring results show that the initial deformation and failure occurred on the protective wall at the slope toe, then gradually developed to the upper part of the slope, and finally led to tensile cracks at the slope trailing edge. Accelerated deformation of the slope support structures, such as the protective wall at the slope toe, the anti-slide pile, and the anchor cable, were observed during the continuous extreme rainfall. The infiltrated rainwater can change the weight, the osmotic pressure, the anti-sliding force, the sliding force of the sliding mass, and further soften the fully weathered tuff soil and reduce its strength, resulting in the landslide occurrence. Block the slope surface runoff is an effective measure to reduce the landslide risk. The current analysis will be helpful to the prevention, control, and emergency disposal of similar landslides.

AbstractFunctional properties caused by TP53 mutations are involved in cancer development and progression. Although most of the mutations lose normal p53 functions, some of them, gain-of-function (GOF) mutations, exhibiting novel oncogenic functions. No reports have analyzed the impact of TP53 mutations on the gene expression profile of the p53 signaling pathway across cancer types. This study is a cross-cancer type analysis of the effects of TP53 mutations on gene expression. A hierarchical cluster analysis of the expression profile of the p53 signaling pathway classified 21 cancer types into two clusters (A1 and A2). Changes in the expression of cell cycle-related genes and MKI67 by TP53 mutations were greater in cluster A1 than in cluster A2. There was no distinct difference in the effects between GOF and non-GOF mutations on the gene expression profile of the p53 signaling pathway.

AbstractMagnetic anchor device based on the principle of magnet heteropolar attraction can assist laparoscopic surgery and reduce abdominal wall trauma. This study explored the feasibility of use of our self-designed magnetic anchor device for reduced-port laparoscopic cholecystectomy (LC) through animal experiments. Twelve experimental pigs (15–20 kg) were randomly divided into study group (magnetic anchor technique assisted 2-port LC, n = 6) and control group (conventional 3-port LC, n = 6). Operative time, intraoperative blood loss, and postoperative complications were compared between the two groups. LC was successfully performed in all 12 pigs. There was no significant between-group difference with respect to operative time (study group: 35.83 ± 5.12 min; control group: 34.50 ± 5.13 min, P = 0.662) or intraoperative blood loss (< 50 mL per animal in both groups). In the experimental group, there was no malfunction of the magnetic anchoring device, the use process was smooth, and the tissue traction and surgical field exposure were satisfactory. There were no perioperative complications such as bile duct injury, bile leakage, or bleeding in both groups. We demonstrated the feasibility of use of the self-designed magnetic anchor device in reduced-port LC. The device has important clinical application value.

Published: March 2023

Purpose:
This study aimed to determine whether articulation assessment via telepractice is as reliable as in-person assessment.

Method:

Thirty-four children aged 4–11 years with speech sound disorder (SSD) participated in the study. The Articulation Subtest (SET) of the Turkish Articulation and Phonology Test (SST) was used to assess the children's articulation skills. The study's procedures comprised two stages. First, in the Baseline Pilot Stage, five speech-language pathologists (SLPs; four graduate SLPs and one SLP with a PhD degree) conducted in-person assessments on seven children, and their agreement was examined (α for five SLPs = .950;
p
< .0001). In the Main Assessment Stage, four SLPs assessed 27 children synchronously on four separate days through either online (two SLPs) or in-person (the other two SLPs) clinician roles, which changed daily. Online evaluators did not use microphones and headphones to avoid any advantage. The agreement among the four raters was examined by calculating the intraclass correlation coefficient.

Results:

The results revealed an excellent level of agreement regarding overall assessment between online and in-person clinicians (
p
< .0001). All articulation manners were acceptable, good, or excellent. However, some sounds' (α < .7 for /d/, /ɣ/, /b/; α < .8 for /p/, /ʃ/, /t/, /l/, /v/) reliability levels were relatively low compared with others.

Conclusions:
There may be certain restrictiveness regarding discriminating visual or auditory clues related to certain phonemes in a telepractice environment. This restrictiveness may be related with sonority and with differentiation between minimal pairs where visual clues are limited.
Compound robust control of permanent magnet synchronous motor based on quasi‐Z source inverter
Authors: Peng Fan , Xie Weicai , Yan Jiande 
Published: March 2023

AbstractIn this study, a compound control strategy for motor side and quasi‐Z source side is proposed to improve the robustness of the quasi‐Z source permanent magnet synchronous motor drive system subjected to external disturbance. In this method, the complementary sliding mode control and sliding mode control as feedback controllers are combined with the disturbance observer technology as a feed‐forward compensator to achieve fast tracking and disturbance suppression for the PMSM drive system. Firstly, the signal models of quasi‐Z source inverters and motors are established. Secondly, by introducing state variables, the composite sliding mode controller is designed with strong robustness based on matched disturbances. Then, in order to further improve the disturbance suppression performance, a disturbance observer based on a feed‐forward compensator is designed to estimate the mismatched external disturbances in the motor drive system. Finally, the global asymptotic stability based on Lyapunov criterion is proved. The simulation and experimental results show that the proposed compound control strategy has the advantages of fast convergence, small motor speed pulsation and strong robustness to external disturbances.

Context.X-ray observations of galaxy clusters are impacted by the presence of active galactic nuclei (AGNs) in a manner that is challenging to quantify, leading to biases in the detection and measurement of cluster properties for both astrophysics and cosmological applications.Aims.We detect and characterise clusters contaminated by central AGNs within the XXL survey footprint and provide a systematic assessment of the cosmological impact of such systems in X-ray cluster samples.Methods.We introduce a new automated class for AGN-contaminated (AC) clusters in the XXL source detection pipeline. The majority of these systems are otherwise missed by current X-ray cluster-detection methods. The AC selection is also effective in distinguishing AGN and cool-core presence using supplementary optical and infrared information.Results.We present 33 AC objects, including 25 clusters in the redshift range, 0.14 ≤ z ≤ 1.03, and eight other sources with significantly peaked central profiles based on X-ray observations. Six of these are new confirmed clusters. We computed the missed fraction of the XXL survey, which is defined as the fraction of genuine clusters that are undetected due to their centrally peaked X-ray profiles. We report seven undetected AC clusters abovez > 0.6, in the range where X-ray cluster detection efficiency drops significantly. The missed fraction is estimated to be at the level of 5% for the 50 square-degree XXL area. The impact on cosmological estimates from missed clusters is negligible for XXL, but it produces a tension of ∼3σwith the fiducial cosmology when considering larger survey areas.Conclusions.This work demonstrates the first systematic attempt to quantify the percentage of missed clusters in X-ray surveys as a result of central AGN contamination. Looking towards surveys such as eROSITA and Athena, larger areas and increased sensitivity will significantly enhance cluster detection, and therefore robust methods for characterising AGN contamination will be crucial for precise cluster cosmology, particularly in the redshiftz > 1 regime.

Published: March 2023

Abstract
Social robots have the potential to support autistic school children with their wellbeing. This research reveals how a co-design approach with autistic children and their teachers was undertaken. Focus groups with autistic children and teachers collaboratively identified user requirements for the social robot and robot behaviours within the school ecosystem in order to improve student wellbeing. The results reveal the importance of including autistic children in the co-design process to ensure their voices are heard and also that the role of the robot is appropriate and targeted to the users’ needs and requirements. Autistic children and their teachers report multiple potential benefits for social robots supporting emotional wellbeing in the school. Autistic children were supportive of the introduction of a social robot in their school, mostly expressing positive attitudes towards the robot. The research is significant in revealing how a user-centred co-design approach involving autistic children and social robots may support emotional wellbeing.
Talking about moving machines

Published: March 2023

Abstract
Globally, robots can be described as some sets of moving parts that are dedicated to a task while using their own energy. Yet, humans commonly qualify those machines as being intelligent, autonomous or being able to learn, know, feel, make decisions, etc. Is it merely a way of talking or does it mean that robots could eventually be more than a complex set of moving parts? On the one hand, the language of robotics allows multiple interpretations (leading sometimes to misreading or confusion in various contexts). On the other hand, the status of robots is challenged more and more by technical achievements and humans’ own empirical beliefs. In this paper, we follow a linguistic approach in order to explore the relevance of these words when talking about robots. Since we note that the words impose themselves (even if opposed), we discuss the efficiency of a rhetorical strategy in order to work with such a lexicon in robotics. More precisely, we explore the argumentative technique of the dissociation of notions through the study of a practical case: the case of robot lawn mowers versus hedgehogs.

Authors: Ye Rong , Yin Ming , Zeng Tingting , Wu Xianyun , Li Hongmei 
Published: March 2023

Abstract
The too intense pre-pulse breaks the conditions of interaction of main pulse with target in experiments where laser pulses interact with matter. An approach of pre-pulse suppression by scanning amplitude limiting is proposed based on quadratic electro-optic effect, according to the characteristics of frequency varies with time of the chirped laser pulse. The scanning amplitude limiting scheme with a Mach-Zehnder interferometer system is depicted and the properties of pre-pulse suppression are analysed both theoretically and numerically. For 800nm central wavelength and magnitude ns duration chirped laser pulse, the simulation result shows that the pre-pulse is suppressed on a scale of 10% to 1‰ or more on the premise of appropriate controlling voltage. Furthermore, the suppressing performance of pre-pulse is sensitive to the deviation and time-delay of voltage which affects the transmittance of system, and it is necessary to reduce the voltage deviation and time-delay so as to suppress the pre-pulse more severe.

Published: March 2023

Abstract
In the field of space optics, correct estimation of the amount of stray light is necessary to evaluate system performance and guide the selection of the correct design. Given the noise target of several picometers on distance measurements, this configuration is very sensitive to stray-light noise; thus, stray-light estimation is an important part of the design process. For complex optical systems, stray-light simulations can be performed by using specific optical analysis software (FRED, Tracepro, ASAP), which require expensive licenses and excessive computing time. Herein, we consider the effects of combined roughness, mirror contamination, and surface imperfections, construct a unified physical scattering model and simulate it. According to the analysis, the stray light of the telescope system is less than 1010 of the outgoing laser power.These considerations apply to various optical systems.

Abstract
Based on the physical meaning of wave equation and Singularity Expansion Method, a numerical solution method is designed to extract the pole distributions of infinite cylinder, sphere and ellipsoid. By analysing the wave equation and boundary conditions of the target scattering characteristics, the extractions of poles of target scattering field are transformed into the solution of Hankel function and its derivative roots. Then, the T-matrix method is improved to make the numerical solution process of roots more accurate and faster. The numerical results are compared with strict analytical solutions and experimental results to fully verify the correctness of the method mentioned in this paper this study provides a basis for understanding the scattering mechanism of surface waves, and also provides a method and idea for solving problems such as acoustic scattering and electromagnetic scattering in engineering practice.

Abstract
Methane is a flammable and explosive gas, which is the main component of natural gas, mashgas, and biogas. Using the technology of tunable diode laser absorption spectroscopy (TDLAS) to detect methane, which does not require oxygen, no poisoning, no calibrating, has gas selectivity, strong environmental adaptability, and is stable and reliable. The laser transmission with the optical fiber has the characteristics of low optical loss, long distance and flexible networking. This manuscript demonstrated an optical fiber laser methane detection device based on TDLAS and its application. The laser was transmitted to the methane detection position by optical fiber, and the laser interacted with methane in the optical fiber gas box. The optical fiber collimator coupled the surplus laser into the optical fiber and sent it back to the monitoring device.The photoelectric detector converted the surplus laser to an electrical signal. The monitoring device operation was based on the principle of TDLAS and analyzed the returned laser strength to obtain the concentration of methane. This manuscript described the principle, composition and monitoring spot network of the fiber laser methane monitoring device and shown a practical application.

Published: March 2023

Abstract
The study of the interaction between laser and composite materials has attracted the attention of many researchers. In this paper, the surface morphology and temperature evolution of T300 carbon fiber composites irradiated by millisecond pulse laser were studied and analyzed experimentally. The transient morphology change process of the front surface of the material was observed by a camera. With the injection of pulsed laser energy, the material began to change its characteristics from the center, leading to a decrease in reflectivity of it, and this area expanded with the accumulation of laser energy. The temperature change on the back of the material was observed by a thermal imager. Within a certain range and the same laser irradiation time, the greater the injected energy per unit area, the faster the temperature of the back center rises. However, under the same circumstances as above, the highest center temperature of the back of the composites is only related to the total energy injected, and has nothing to do with the spot size.

Abstract
With the gradual improvement of optical interconnection technology’s requirements for high-speed broadband transmission of data, multidimensional multiplexing technology must be used to meet the application scenarios. Among them, polarization multiplexing technology has opened up a higher multiplexing dimension, and the application prospects are very broad. Polarization beam splitters have received a lot of attention as a key device in polarization multiplexing technology. The polarization multiplexer designed by traditional design methods with the help of classical theory and empirical calculation generally has deficiencies such as excessive volume and complex design, which is not conducive to large-scale integration, and the introduction of inverse design can effectively solve this problem and improve design efficiency. In this paper, the polarization beam splitter is implemented by using the inverse design, which can realize the output of the modes TE0 and TM0 in the bus waveguide from the respective regional waveguides, and the integration of TE0 and TM0 in the respective branch waveguides into the fusion transmission in the bus waveguide, with a size of only 2.4μm × 2μm. At the same time, simulation experiments show that the insertion loss of the device in the operating wavelength range of 1520nm to 1580nm is less than 1.4dB, and the crosstalk value between channels is almost negligible because the core layer of 220nm is difficult to achieve polarization rotation.

Published: March 2023

Abstract
Fiber Bragg gratings are widely used in sensing fields, but few studies about their stability have been reported. A high-resolution π-phase shift FBG (π-FBG) ocean temperature sensor is experimentally demonstrated by using a linearized optical frequency sweeping interrogation system. A gas absorption line from H13C14N (HCN) gas was used to calibrate the laser frequency in real-time, providing long-term stability of the demodulation system. The temperature coefficient of π-FBG is ~14pm/°C, the temperature-resolution is as high as 0.001 °C and the response time is 49.45ms. In order to study the stability of the π-FBG probe, it is placed in a Gallium point bottle with a constant temperature point. Over the course of 4 hours of continuous testing, the probe exhibited a linear drift of approximately 0.09°C.
Auto-Focusing in Digital Holographic Microscopy Using Differential Cosine Score

Published: March 2023

Abstract
Accurately estimating the reconstruction distance of samples is very important for digital holographic microscopy, various auto-focusing algorithms have been proposed. These algorithms determine focus position by finding the global peak or valley of the evaluation curve. However, the discrete step size is small in precise autofocus process, which causes that the function values around peak or valley are not much different. As a result, the sensitivity of the peak and valley values of the evaluation curve is low, and the focusing accuracy is also susceptible to noise. In this paper, an autofocusing method using differential cosine score (DCS) is proposed to improve the accuracy and sensitivity of evaluation curve. In this method, two virtual detectors are placed on both sides of the real detector at the same distance. Two ordinary focusing curves and one DCS curve can be obtained by using the cosine score function. Therefore, the focal plane can be automatically identified by searching the zero-crossing of DCS curve, which avoids the problem of low sensitivity of peak and valley values by traditional methods. We illustrate the validity of the proposed method with measurements on USAF resolution target, blood smear and Hela cell.
