Metabolic stable isotope labeling with heavy water followed by liquid chromatography coupled with mass spectrometry (LC-MS) is a powerful tool for in vivo protein turnover studies. Several algorithms and tools have been developed to determine the turnover rates of peptides and proteins from time-course stable isotope labeling experiments. The availability of benchmark mass spectrometry data is crucial to compare and validate the effectiveness of newly developed techniques and algorithms. In this work, we report a heavy water-labeled LC-MS dataset from the murine liver for protein turnover rate analysis. The dataset contains eighteen mass spectral data with their corresponding database search results from nine different labeling durations and quantification outputs from d2ome+ software. The dataset also contains eight mass spectral data from two-dimensional fractionation experiments on unlabeled samples.

The classical hypothesis proposes that the lack of recombination on sex chromosomes arises due to selection for linkage between a sex-determining locus and sexually antagonistic loci, primarily facilitated by inversions. However, cessation of recombination on sex chromosomes could be attributed also to neutral processes, connected with other chromosome rearrangements or can reflect sex-specific recombination patterns existing already before sex chromosome differentiation. Three Coleonyx gecko species share a complex X1X1X2X2/X1X2Y system of sex chromosomes evolved via a fusion of the Y chromosome with an autosome. We analyzed synaptonemal complexes and sequenced flow-sorted sex chromosomes to investigate the effect of chromosomal rearrangement on recombination and differentiation of these sex chromosomes. The gecko sex chromosomes evolved from syntenic regions that were also co-opted also for sex chromosomes in other reptiles. We showed that in male geckos, recombination is less prevalent in the proximal regions of chromosomes and is even further drastically reduced around the centromere of the neo-Y chromosome. We highlight that pre-existing recombination patterns and Robertsonian fusions can be responsible for the cessation of recombination on sex chromosomes and that such processes can be largely neutral.
Intermediate LET-like effect in distal part of proton Bragg peak revealed by track-ends imaging during super-Fricke radiolysis

Published: September 2023

Upstream of the efficiency of proton or carbon ion beams in cancer therapy, and to optimize hadrontherapy results, we analysed the chemistry of Fricke solutions in track-end of 64-MeV protons and 1.14-GeV carbon ions. An original optical setup is designed to determine the primary track-segment yields along the last millimetres of the ion track with a sub-millimetre resolution. The Fe3+-yield falls in the Bragg peak to (4.9 ± 0.4) × 10–7 mol/J and 1.9 × 10–7 mol/J, under protons and carbon ions respectively. Beyond the Bragg peak, a yield recovery is observed over 1 mm for proton beams. It is attributed to the intermediate-LET of protons in this region where their energy decreases and energy distribution becomes broader, in relation with the longitudinal straggling of the beam. Consequently to this LET decrease in the distal part of the Bragg peak, Fe3+-yield increases. For the first time, this signature is highlighted at the chemical level under proton irradiation. Nevertheless, this phenomenon is not identified for carbon ion beams since their straggling is lower. It would need a greater spatial resolution to be observed.

Published: September 2023

Oxidative stress has been shown to induce cell death in a wide range of human diseases including cardiac ischemia/reperfusion injury, drug induced cardiotoxicity, and heart failure. However, the mechanism of cell death induced by oxidative stress remains incompletely understood. Here we provide new evidence that oxidative stress primarily induces ferroptosis, but not apoptosis, necroptosis, or mitochondria-mediated necrosis, in cardiomyocytes. Intriguingly, oxidative stress induced by organic oxidants such as tert-butyl hydroperoxide (tBHP) and cumene hydroperoxide (CHP), but not hydrogen peroxide (H2O2), promoted glutathione depletion and glutathione peroxidase 4 (GPX4) degradation in cardiomyocytes, leading to increased lipid peroxidation. Moreover, elevated oxidative stress is also linked to labile iron overload through downregulation of the transcription suppressor BTB and CNC homology 1 (Bach1), upregulation of heme oxygenase 1 (HO-1) expression, and enhanced iron release via heme degradation. Strikingly, oxidative stress also promoted HO-1 translocation to mitochondria, leading to mitochondrial iron overload and lipid reactive oxygen species (ROS) accumulation. Targeted inhibition of mitochondrial iron overload or ROS accumulation, by overexpressing mitochondrial ferritin (FTMT) or mitochondrial catalase (mCAT), respectively, markedly inhibited oxidative stress-induced ferroptosis. The levels of mitochondrial iron and lipid peroxides were also markedly increased in cardiomyocytes subjected to simulated ischemia and reperfusion (sI/R) or the chemotherapeutic agent doxorubicin (DOX). Overexpressing FTMT or mCAT effectively prevented cardiomyocyte death induced by sI/R or DOX. Taken together, oxidative stress induced by organic oxidants but not H2O2 primarily triggers ferroptotic cell death in cardiomyocyte through GPX4 and Bach1/HO-1 dependent mechanisms. Our results also reveal mitochondrial iron overload via HO-1 mitochondrial translocation as a key mechanism as well as a potential molecular target for oxidative stress-induced ferroptosis in cardiomyocytes.
Reservoir computing using self-sustained oscillations in a locally connected neural network
Authors: Kawai Yuji , Park Jihoon , Asada Minoru
Published: September 2023

Understanding how the structural organization of neural networks influences their computational capabilities is of great interest to both machine learning and neuroscience communities. In our previous work, we introduced a novel learning system, called the reservoir of basal dynamics (reBASICS), which features a modular neural architecture (small-sized random neural networks) capable of reducing chaoticity of neural activity and of producing stable self-sustained limit cycle activities. The integration of these limit cycles is achieved by linear summation of their weights, and arbitrary time series are learned by modulating these weights. Despite its excellent learning performance, interpreting a modular structure of isolated small networks as a brain network has posed a significant challenge. Here, we investigate how local connectivity, a well-known characteristic of brain networks, contributes to reducing neural system chaoticity and generates self-sustained limit cycles based on empirical experiments. Moreover, we present the learning performance of the locally connected reBASICS in two tasks: a motor timing task and a learning task of the Lorenz time series. Although its performance was inferior to that of modular reBASICS, locally connected reBASICS could learn a time series of tens of seconds while the time constant of neural units was ten milliseconds. This work indicates that the locality of connectivity in neural networks may contribute to generation of stable self-sustained oscillations to learn arbitrary long-term time series, as well as the economy of wiring cost.

N-methyl-D-aspartate receptors (NMDARs) are ligand-gated ionotropic glutamate receptors that mediate a calcium-permeable component to fast excitatory neurotransmission. NMDARs are heterotetrameric assemblies of two obligate GluN1 subunits (GRIN1) and two GluN2 subunits (GRIN2A-GRIN2D). Sequencing data shows that 43% (297/679) of all currently known NMDAR disease-associated genetic variants are within the GRIN2A gene, which encodes the GluN2A subunit. Here, we show that unlike missense GRIN2A variants, individuals affected with disease-associated null GRIN2A variants demonstrate a transient period of seizure susceptibility that begins during infancy and diminishes near adolescence. We show increased circuit excitability and CA1 pyramidal cell output in juvenile mice of both Grin2a+/− and Grin2a−/− mice. These alterations in somatic spiking are not due to global upregulation of most Grin genes (including Grin2b). Deeper evaluation of the developing CA1 circuit led us to uncover age- and Grin2a gene dosing-dependent transient delays in the electrophysiological maturation programs of parvalbumin (PV) interneurons. We report that Grin2a+/+ mice reach PV cell electrophysiological maturation between the neonatal and juvenile neurodevelopmental timepoints, with Grin2a+/− mice not reaching PV cell electrophysiological maturation until preadolescence, and Grin2a−/− mice not reaching PV cell electrophysiological maturation until adulthood. Overall, these data may represent a molecular mechanism describing the transient nature of seizure susceptibility in disease-associated null GRIN2A patients.

A model for the infrared-radio correlation of main sequence galaxies at gigahertz frequencies and its variation with redshift and stellar mass
Authors: Schober J. , Sargent M. T. , Klessen R. S. , Schleicher D. R. G.
Published: September 2023

Context. The infrared-radio correlation (IRRC) of star-forming galaxies can be used to estimate their star formation rate (SFR) based on the radio continuum luminosity at MHz–GHz frequencies. For its practical application in future deep radio surveys, it is crucial to know whether the IRRC persists at high redshift z.

Aims. Previous works have reported that the 1.4 GHz IRRC correlation of star-forming galaxies is nearly z-invariant up to z ≈ 4, but depends strongly on the stellar mass M⋆. This should be taken into account for SFR calibrations based on radio luminosity.

Methods. To understand the physical cause behind the M⋆ dependence of the IRRC and its properties at higher z, we constructed a phenomenological model for galactic radio emission. Our model is based on a dynamo-generated magnetic field and a steady-state cosmic ray population. It includes a number of free parameters that determine the galaxy properties. To reduce the overall number of model parameters, we also employed observed scaling relations.

Results. We find that the resulting spread of the infrared-to-radio luminosity ratio, q(z, M⋆), with respect to M⋆ is mostly determined by the scaling of the galactic radius with M⋆, while the absolute value of the q(z, M⋆) curves decreases with more efficient conversion of supernova energy to magnetic fields and cosmic rays. Additionally, decreasing the slope of the cosmic ray injection spectrum, αCR, results in higher radio luminosity, decreasing the absolute values of the q(z, M⋆) curves. Within the uncertainty range of our model, the observed dependence of the IRRC on M⋆ and z can be reproduced when the efficiency of supernova-driven turbulence is 5%, 10% of the kinetic energy is converted into magnetic energy, and αCR ≈ 3.0.

Conclusions. For galaxies with intermediate to high (M⋆ ≈ 109.5 − 1011 M⊙) stellar masses, our model results in an IRRC that is nearly independent of z. For galaxies with lower masses (M⋆ ≈ 108.5 M⊙), we find that the IR-to-radio flux ratio increases with increasing redshift. This matches the observational data in that mass bin which, however, only extends to z ≈ 1.5. The increase in the IR-to-radio flux ratio for low-mass galaxies at z ≳ 1.5 that is predicted by our model could be tested with future deep radio observations.
CRIRES-POP: A library of high resolution spectra in the near-infrared
Authors: Zendel M. , Lebzelter T. , Nicholls C. P.
Published: September 2023

Context. High-resolution spectra in the near-infrared (NIR) are an important tool for the detailed study of stellar atmospheres. The accurate identification of elements and molecules in these spectra can be used to determine chemical abundances and physical conditions in the photosphere of the observed star. Such identifications require precise line positions and strengths of both atomic and molecular features.

Aims. This work focusses on the full identification of absorption lines in the NIR spectrum of the K-giant 10 Leo, including previously unidentified lines. The large number and complexity of the observed absorption lines require a deep search for potential spectral signatures to enable an unambiguous assignment to specific elements or molecular species. We aim to improve the published line lists of metals, some of which are determined by model calculations only, and many of which presently lack the completeness and accuracy of line parameters.

Methods. The CRIRES-POP project provided high-resolution, high signal-to-noise ratio (S/N) spectra of several bright stars in the 1–5 μm range. For the K-giant 10 Leo, a spectrum corrected for telluric absorption and with precise wavelength calibration is available. This has been analysed by comparison with model spectra and up-to-date line lists.

Results. We identified lines of 29 elements and eight molecular species. While the positions of many known lines could be confirmed, about 6% of all lines detected in 10 Leo could not be attributed to any known feature. For CO and its isotopologues, molecular constants could be derived and several additional lines identified. We report major inconsistencies for some prominent lines. In addition, abundances for several key elements in 10 Leo are provided.
Awake Uniportal VATS for the Evacuation of an Extensive, Superinfected Hemothorax in a Patient with Advanced Mediastinal SMARCA4-Deficient Tumor
Authors: Lobinger Dominik , Reiche Alicia , Hiebinger Andreas , Bodner Johannes
Published: September 2023

Background The so-called nonintubated or awake video-assisted thoracoscopic surgery (NIVATS) is performed on spontaneously breathing patients, which was shown to reduce postoperative complications and shorten hospital stay.

Case Description Awake uniportal VATS was indicated for the evacuation of an extensive, superinfected hemothorax with symptomatic mediastinal shift in a patient with advanced mediastinal SMARCA4-deficient tumor and declined condition, who did not allow a general anesthetic procedure and was not a candidate for extensive surgery.

Conclusion This short microinvasive intervention was a prerequisite to stabilize the threat to the patient's life and thus potentially enable any further tumor-specific therapy.
Laryngeal Imaging: Anatomy and Pathology

Published: September 2023

Imaging plays an important role in diagnostic evaluation of laryngeal lesions. The real value of imaging comes when there is a need to decide the feasibility of speech conservation therapy. Cross-sectional imaging allows excellent depiction of the intricate anatomy of the larynx and the characteristic patterns of tumor extension as well as the status of cervical nodal disease. Imaging studies also help in the post-therapeutic follow-up of patients with laryngeal cancers. In this article, we review the currently used laryngeal imaging techniques and protocols, the key anatomic structures relevant to tumor spread and the characteristic patterns of submucosal extension and invasion of laryngeal cancer. The role of CT and MRI in the evaluation of patients with laryngeal SCC and the impact of imaging findings, staging and surgical aspects is also discussed.

Published: September 2023

Pelvic floor, a funnel-shaped muscular structure plays a significant role in bowel and bladder activities. Defecatory disorders result from the structural changes and functional disorders. Pelvic floor dysfunction affects 15% of multiparous women. It is being expected that after 30 years, there would be 45% rise in demand of pelvic floor imaging. After ruling out primary and secondary causes of constipation, diagnosis of obstructed defecation syndrome (ODS) is made. ODS is emerging as one of the important causes of constipation. As the symptoms are nonspecific and examination findings are frequently inaccurate, the clinical evaluation becomes a difficult task. Hence, various imaging modalities are becoming popular as an adjunct tool for the assessment of these disorders. Clinical management of ODS is based on the Constipation and Bowel Activity Score (CABA) and delineation of the pelvic floor anatomy. After defining the pelvic floor anatomy–based structural abnormality, day care ambulatory surgical procedure, that is, stapled transanal resection rectopexy (STARR), is offered to the patients of ODS. It provides significant relief to patients suffering from constipation and reduction in postoperative CABA score. This review discusses the role of magnetic resonance defecography imaging in ODS its impact on subsequent management.

Authors: Bensouda Brahim , Mandel Romain , Mejri Abdelwaheb , Tordjman Laurent , St-Hilaire Marie , Ali Nabeel
Published: September 2023

Objective There is no recommendation in the literature on optimal positioning of the newborn immediately at birth during delayed cord clamping. To evaluate if prone positioning on the mother's chest at birth during delayed cord clamping leads to a higher hematocrit at 30 hours of life compared to supine positioning.

Study Design A randomized unblinded trial comparing prone and supine position of the newborn before umbilical cord clamping. Healthy newborns ≥36 weeks gestational age and born vaginally with cephalic presentation were included. The newborn was randomized to prone or supine position. Umbilical cord clamping was delayed in both groups to 1 minute after birth. The primary outcome was hematocrit at 30 hours of life. As a secondary outcome, cerebral tissue oxygenation (CrSO2) values were compared between both groups by near infrared spectroscopy.

Results There was no difference in hematocrit at 30 hours of life between supine and prone positions with a mean at 52 and 53.1, respectively, mean difference −1.1 (95% confidence interval:−2.7, 0.5), p = 0.17. Newborns in supine and prone positions had comparable level of CrSO2 at 30 hours of life with a mean at 84.1 and 82.2, respectively, mean difference 1.9 (−0.2, 4.0), p = 0.07. There was no correlation between hematocrit and CrSO2 at 30 hours of life (r = 0.14).

Conclusion There was no difference between prone and supine positioning immediately after birth during delayed cord clamping on hematocrit at 30 hours of life. In the absence of clear findings, further studies with assessment of the effect of position on breastfeeding success in the case room, on maternal satisfaction and outcome beyond 30 hours are needed to make adequate recommendations on positioning.

Key Points
The imitation game: indirect European Union influence on municipal officials’ attitudes towards elite corruption and informal payments
Authors: Sircar Indraneel
Published: September 2023

The European Union has sought to democratise its post-communist neighbours for the past three decades, starting with Central and Eastern Europe after 1989. Since the end of the wars in Former Yugoslavia in 2000, the EU first pursued closer integration with the Western Balkans followed by the goal of enlargement. However, despite intensive EU involvement, the fight against corruption has stagnated or deteriorated in post-communist Europe, particularly in Former Yugoslavia. The central question in the article is whether indirect EU influence has led municipal officials—who are at the front line of vital distributive decision-making for citizens at the local level—to imitate (or emulate) attitudes related to corruption and to informality in line with EU norms. The article focuses on the case of Serbia, where anti-corruption progress has been particularly slow. Using a survey of Serbian municipal officials, the article examines whether indirect EU influence via involvement in policy implementation affected attitudes towards informal payments, and through a vignette-based survey experiment, whether those involved in EU-compliant policy implementation are less accepting of local political elite corruption.
Risk identification approaches and the number of risks identified: the use of work breakdown structure and business process
Authors: Kountur Ronny , Sari Martdian Ratna
Published: September 2023

Losses and damages that any company or organization experience is usually caused by some unidentified risks that hit them unprepared. Some companies even must close their business or discontinue their operation due to the huge negative impact of the risk that hit them. Knowing the risks that an organization face is important. Risk needs to be identified properly. Though there had been some approaches a person can use in identifying risk, most of those approaches are complex, require several people involved, are too subjective, and are not able to identify unseen risks. Therefore, the purpose of this study is to know which risk identification method can identify more risks when knowledge of the context is controlled. The study made use of experimental research design with the use of covariance analysis in analyzing the data. With a 95% level of confidence, it was found that risk identification methods affect the number of risks identified. The business process approach seems to identify more risks than the work breakdown structure approach and placebo. The step-by-step procedures in doing the business process approach and work breakdown structure approach are also introduced in this study.
Microfluidic pumps for cell sorting

Published: September 2023

Microfluidic cell sorting has shown promising advantages over traditional bulky cell sorting equipment and has demonstrated wide-reaching applications in biological research and medical diagnostics. The most important characteristics of a microfluidic cell sorter are its throughput, ease of use, and integration of peripheral equipment onto the chip itself. In this review, we discuss the six most common methods for pumping fluid samples in microfluidic cell sorting devices, present their advantages and drawbacks, and discuss notable examples of their use. Syringe pumps are the most commonly used method for fluid actuation in microfluidic devices because they are easily accessible but they are typically too bulky for portable applications, and they may produce unfavorable flow characteristics. Peristaltic pumps, both on- and off-chip, can produce reversible flow but they suffer from pulsatile flow characteristics, which may not be preferable in many scenarios. Gravity-driven pumping, and similarly hydrostatic pumping, require no energy input but generally produce low throughputs. Centrifugal flow is used to sort cells on the basis of size or density but requires a large external rotor to produce centrifugal force. Electroosmotic pumping is appealing because of its compact size but the high voltages required for fluid flow may be incompatible with live cells. Emerging methods with potential for applications in cell sorting are also discussed. In the future, microfluidic cell sorting methods will trend toward highly integrated systems with high throughputs and low sample volume requirements.
Measuring residual transpiration in plants: a comparative analysis of different methods
Authors: Hasanuzzaman Md. , Chakraborty Koushik , Zhou Meixue , Shabala Sergey
Published: September 2023

Residual transpiration (RT) is defined as a loss of water through the leaf cuticle while stomata are closed. Reduced RT might be a potentially valuable trait for improving plant performance under water deficit conditions imposed by either drought or salinity. Due to the presence of stomata on the leaf surface, it is technically challenging to measure RT. RT has been estimated by the water loss through either astomatous leaf surface or isolated astomatous cuticular layers. This approach is not suitable for all species (e.g. not applicable to grasses) and is difficult and too time consuming for large-scale screening in breeding programs. Several alternative methods may be used to quantify the extent of RT; each of them comes with its own advantages and limitations. In this study, we have undertaken a comparative assessment of eight various methods of assessing RT, using barley (Hordeum vulgare) plants as a model species. RT measured by water retention curves and a portable gas exchange (infrared gas analyser; IRGA) system had low resolution and were not able to differentiate between RT rates from young and old leaves. Methods based on quantification of the water loss at several time-points were found to be the easiest and least time-consuming compared to others. Of these, the ‘three time-points water loss’ method is deemed as the most suitable for the high throughput screening of plant germplasm for RT traits.
“You are fake news”

Using the methodology of conversation analysis and a modified analytical framework, this article attempts to
characterize and investigate Trump’s practices to resist the agendas of the interviewers’ questions during the press briefings
held by the Trump Administration in 2020. Statistical data show that Trump mainly used four types of overt resistant response
practices in order of decreasing frequency: (1) Justifying the resistance; (2) Providing a partial answer; (3) Flatly
refusing to answer without any explanation; and (4) Resorting to a personal attack, which is a new type of overt resistant
practices. However, only one type of covert resistant response practice is identified, i.e. Repeating words subversively. The
potential reasons for Trump’s use of such practices are discussed. In essence, Trump’s deliberate use of resistant response

Improving the adhesion of CrN coatings on TC4 alloy substrates by discharge current modulation in magnetron sputtering
Authors: Xu Shuai , Zhao Zhuo , Zhou Yanwen , Zhang Kaice
Published: September 2023

The study reports the formation of multilayer coatings of CrN with variable gradient modulus on TC4 substrate by varying the discharge current of the hot filament in magnetron sputtering. Results show that multilayer CrN/TC4 has a higher critical failure load (63.4 N > 29.7 N), lower maximum tensile stress (103.8 GPa < 134.3 GPa), and a higher ratio of plastic to elastic deformation work (Wp/We, 2.11 > 1.58) than a single layer CrN/TC4. This indicates that the energy absorption ability of the coating/substrate before failure can be improved by increasing the loose energy-absorbing sublayer, thus improving the coating/substrate adhesion. Notably, the wear rate of both multilayer and single-layer coatings is in the order of 10−16 m3/(N·m), demonstrating their excellent wear resistance. Structural engineering enables the application of multilayer CrN coatings on low-modulus and high-strength alloy substrates, such as TC4.

Published: September 2023

In the realm of quantum information processing and precision measurements, a range of non-classical effects based on entangled photon pairs are employed. Non-local dispersion cancellation is one of these properties, in which the second photon (idler) can be manipulated to cancel the effects of dispersion on the first photon (signal). In the present study, a thorough investigation is conducted into non-local dispersion cancellation by using excitation modes within a Bragg grating slab waveguide. We present a complete theoretical analysis of non-local dispersion cancellation for frequency-limited entangled photon pairs. For the analysis of the effect of dispersion cancellation, we use a spontaneous parametric down-conversion (SPDC) photon pair source with frequency correlation and anti-correlation as the entangled source. To evaluate the dispersion cancellation effect for information processing applications, the second correlation function is used and calculated as a practical and tangible metric. Considering different cases for Bragg Grating waveguide the results on both photons are extracted and discussed. Moreover, we will show that the physical parameters of the waveguide that the second photon is propagated inside will be effective in minimizing the width of the temporal correlation function. Hence, this study underscores the feasibility of achieving non-local dispersion cancellation through strategic optimization of optical and geometric parameters in the Bragg Grating waveguide, with potential implications for quantum information processing and high-resolution sensing endeavors.

A Hamiltonian system is derived for the plane elasticity problem of two-dimensional dodecagonal quasicrystals by introducing the simple state function. By using symplectic elasticity approach, the analytic solutions of the phonon and phason displacements are obtained further for the quasicrystal plates. In addition, the effectiveness of the approach is verified by comparison with the data of the finite integral transformation method.

Published: September 2023

Magnetic semiconductors have attracted a lot of attention by having both electronic charge and spin degrees of freedom. In this paper, we obtained twenty magnetic semiconductors such as FeVLaSb, FeVPrSb, FeCrTbSi, CoVDySi, and CoVHoSi by adding lanthanides to quaternary Heusler compounds based on the Slater–Pauling law and orbital hybridization theory. The relationship between the lattice constants and energy gaps of the magnetic semiconductors with lanthanide elements is investigated by in-depth analysis. These magnetic semiconductors of quaternary Heusler compounds are promising candidates to find applications as spin filtering materials in spintronics devices.

Published: September 2023

We investigate the possible anisotropy of the universe using data on the most up-to-date type Ia supernovae, i.e., the Pantheon+ compilation. We fit the full Pantheon+ data with the dipole-modulated ΛCDM model and find that the data are well consistent with a null dipole. We further divide the full sample into several subsamples with different high-redshift cutoffs

. It is shown that the dipole appears at the

confidence level only if

away from the CMB dipole. This implies that the full Pantheon+ sample is consistent with a large-scale isotropic universe, but the low-redshift anisotropy could not be purely explained by the peculiar motion of the local universe.

Asymptotic analysis of the angular motion of a projectile based on Lyapunov artificial-small-parameter perturbation
Authors: Wang Chen , Ding Libo
Published: September 2023

In the traditional analysis of the angular motion of a projectile, the coefficient freezing method is often used to simplify the differential equation of angular motion. However, this method gives a poor approximation for long time scales. In this paper, based on Lyapunov artificial-small-parameter perturbation theory, an asymptotic analytical solution for the angular motion of a projectile is derived by constructing artificial small parameters for the variable coefficient terms in the original equation. In an example, the angular motion of a single-channel rotating projectile with two-dimensional trajectory correction was analyzed. The method proposed in this paper was compared with the coefficient freezing method. The results show that the proposed method can give a good approximation over a long time scale. This study may be significant for the solution of differential equations with variable coefficients and may be useful for certain engineering applications.

Authors: Chen Xiangzhi , Tang Lihua , Zhong Yuansheng
Published: September 2023

Collision safety of mobile robot is one of the important indexes of robot safety evaluation. The acceleration signal of the robot can completely feed-back the state of the collision process, but it is also vulnerable to noise interference such as vibration and impact, which is difficult to be used for direct analysis. In order to solve the problem of mixing acceleration signal with impact noise and periodic vibration noise during robot collision, a combined filtering noise reduction method based on empirical mode decomposition (EMD), improved wavelet threshold method and dynamic sliding window is proposed. And a wavelet adaptive threshold function is constructed. The wavelet coefficients are automatically adjusted using the information of decomposition degree and noise level, and a dynamic adjustment strategy of sliding window length is designed. The acceleration information of robot can be effectively extracted in the process of strong noise collision. The experimental results show that this method has better noise reduction effect than other methods.
Research on low speed control position observer for accumulator electric locomotive PMSM
Authors: Zhu Longji , Shao Hua , Wang Xiaohu
Published: September 2023

The PMSM of accumulator electric locomotive is generally controlled without position sensor, but the traditional position observer has the low speed observation accuracy, and the nonlinear factors of many mechanical parameters, such as torque feedback and moment of inertia, interfere with the low dynamic performance of the motor control system. A position observation model based on the nonlinear expansion observer is designed. The position observation model is constructed by using the relationship among the speed of the motor, the position angle of the rotor and its angular acceleration as well as the nonlinear function. Because it can avoid measuring the load torque and using the nonlinear expansion observer to estimate the uncertain disturbance, it is easy to realize. The simulation results show that the position observer can make the electric locomotive run stably under low speed control and has good low speed dynamic performance.
Model prediction controller for penetration mechanism of seabed cone penetration test system
Authors: Wang Shimin , Ren Ziqiang , Zhou Hang , Chen Jiawang
Published: September 2023

The system of seabed Cone Penetration Test (CPT) is a kind of equipment for offshore investigations. Seabed CPT is used to assess multiple physical properties of marine sediments. Constant-rate penetration mechanism is the core part of seabed CPT, which adopts dual-cylinder drive to penetrate the probe rod into the seafloor sediments at a constant speed (2cm/s). At present, the domestic CPT and its penetration equipment almost all rely on imports. In the process of system design, we found that the traditional PID control of the hydraulic cylinder position control accuracy is low, so we need to study higher precision position tracking control method to achieve uniform penetration of the probe rod. In this paper, a Linear Time-Varying Model Predictive Controller (LTV-MPC) is introduced, which can control two hydraulic cylinders to penetrate probe rod into the seabed sediment with smaller penetration rate error under the condition of changing penetration resistance.
