Published: September 2024

Abstract
Objective To describe a modification of the tibial plateau leveling osteotomy technique wherein a double cut is made in the same plane to level the tibial plateau (double-cut tibial plateau leveling osteotomy [DCTPLO]) for treating dogs with cranial cruciate ligament (CrCL) and excessive tibial plateau angle (eTPA) diseases.
Study Design The DCTPLO technique was performed on 18 stifles in dogs with CrCL and an eTPA (>34°). This study evaluated the accuracy of preoperative planning, feasibility of the technique, postoperative clinical outcomes, radiographic examinations at the postoperative follow-up for the first 120 days, evolution of the tibial plateau angle (TPA), time of union of the osteotomy, apposition of the implants, and possible complications.
Results The described technique proved to be feasible for clinical application, with reproducibility from preoperative planning. An effective reduction in the eTPA levels was observed. The mean preoperative and postoperative TPA values were 39.4° (36°–43.5°) and 6.3° (3°–13°), respectively. Radiographic healing time was 60 days in 17/18 of stifles. Minor complications (not requiring surgical review or clinical treatment) were observed in 4/18 of stifles.
Conclusion The DCTPLO technique was effective for treating CrCL disease with TPA of up to 43.5° in dogs.
The rhotics of the Salvador, Bahia variety of Brazilian Portuguese
Authors: Jagiella Trey , Clements J. Clancy 
Published: September 2024

Abstract
Brazilian Portuguese has two rhotic phonemes: the alveolar flap /ɾ/ and another variable phoneme. This phoneme has
been cited as velar, uvular, and glottal fricatives, as well as alveolar trills and approximants. Variability of surface forms
occurs both within and across varieties. This phoneme occurs in simple onsets, codas, and intervocalically. Deletion of the
phoneme is common, particularly in word-final position. The goal of this project is to explore the variation in rhotic production
in Salvador, particularly with regards to substrate influence. Ten participants read predetermined stimuli of isolated tokens and
sentences, with a total of 1409 instances of the phoneme. The findings indicate that the range of possible surface forms is more
variable than previously cited, including palatal and uvular fricatives among others. We suggest that the degree of variability of
rhotic production in Salvador may be due to past contact between Africans and Portuguese in the city.
Modeling Linguistic Landscapes
Authors: Buschfeld Sarah , Weihs Claus , Ronan Patricia 
Published: September 2024

Abstract
Much work in Linguistic Landscapes approaches multilingual landscapes in qualitative terms; inferential
statistical approaches are still underrepresented. The present paper adds to filling this methodological gap by investigating the
Linguistic Landscapes of St Martin, a highly multilingual, eastern Caribbean island, divided into a formerly Dutch-colonized and
French-colonized part. It does so by employing an inferential statistical method to study the nature of linguistic diversity on
signs. Based on 372 and 373 signs respectively for each of the commercial districts of Philipsburg and Marigot, we quantitatively
analyze the occurrences of languages on the different signs and statistically model the data by means of Multi-Label
Classification (MLC; e.g. Rivolli & de Carvalho, 2018). The results show that both
shopping districts are characterized by multilingual patterns of Linguistic Landscapes but with differences in their exact
linguistic setups, most importantly the interplay and relationships between different languages, motivated by differences in their
sociolinguistic setup.
Towards a distinction between non-euphemistic and euphemism-based politically correct expressions
Authors: Golubeva Tatiana 
Published: September 2024

Abstract
This qualitative research is the first attempt to analyse differences in the interpretation of politically correct (PC) expressions by using relevance-theoretic and lexical pragmatics tools. The results suggest that PC language can be non-euphemistic and euphemism-based. Non-euphemistic PC expressions achieve relevance by explicitly communicating their lexically encoded conceptual content. Euphemism-based PC expressions become relevant by communicating some concepts and propositions that are not lexically encoded by them and are inferred logically from the utterance context or/and by accessing encyclopaedic information. These concepts and propositions constitute euphemistic meaning and are recovered at explicit and implicit levels, as well as with varying degrees of strength.
The relationship between nutrition and intestinal health in newborn lambs
Authors: Uysal Soner , Uysal Ayse 
Published: September 2024

Abstract
As with all animals, the period in their lives when lambs are most vulnerable is the period before and immediately after birth. Because this period (the suckling period) is the period of clinging to life in an environment open to microorganism contamination after the sterile uterine environment. It is very important that this difficulty can be reduced with good care and feeding practices that must be applied during this period and that the puppy lamb can have a healthy and highly productive life during this risky period and in the future. Regulation and enhancement of the intestinal microbiome is a crucial aspect for optimizing the health and performance of farm animals. This is mainly because diet and management practices greatly affect the intestinal microbiota, resulting in changes in nutrient utilization and the immune system. The intestinal health of newborn lambs is affected by feeding manipulations, as in other ruminants. In this review, the suckling period and digestive system development in newborn lambs are mentioned. Additionally, this review discusses some practices to manipulate intestinal development and microbial colonization in order to improve the production and health of newborn lambs at an early age when they are most susceptible to enteric diseases.

Published: September 2024

Abstract
In order to satisfy the market’s demand for high-consistency, micro-dispensing of colloids, an embedded lever-amplified piezoelectric dispensing valve based on flexure hinge is designed. This structure has stable jetting performance, strong reliability, and can achieve micro-dispensing of medium and low viscosity glue. Theoretical analysis shows that the output displacement of the piezoelectric stack can meet the displacement requirement of dispensing after being amplified by this amplification mechanism. And the output displacement and mode of the amplification mechanism are calculated and analyzed by simulation. The rationality of the simulation model is verified by experiments, and the effect law of driving voltage, signal duty cycle and working frequency on the mass of glue droplets is obtained. The results show that under the conditions of driving voltage 100 V, duty cycle 50%, glue supply pressure 0.6 MPa, working frequency 100 Hz, the consistency deviation of single dispensing amount is ±2.01%, as a whole, 0.34–0.38 mg of uniform tiny glue dots can be obtained. The experimental results have verified the stability and micro-dispensing performance of the embedded lever amplification piezoelectric dispensing valve, providing reference for the subsequent application and research of jet dispensing.
Influence factors and improvement scheme on the breakdown behavior of pseudospark switch
Authors: Yuan Qi , Sun Guoxiang , Xue Haorui , Ding Weidong , Nie Shaohao , Yu Kunhao 
Published: September 2024

Abstract
High-power pulse generators are widely used in civil and military fields. The main switch directly determines the output characteristics of the high-power pulse generators, such as the voltage front time (t
f). Pseudospark switches (PSS) show a promising future for middle voltage, high repetitive frequency pulse power applications. However, how to further improve the breakdown behavior without reducing its advantages is a challenging task. In this paper, the influence of operating parameters (anode voltage U
A and gas pressure p) and structural parameter (number of cathode holes) on the breakdown behavior are investigated, the related mechanism are explained, and specific improvement schemes are proposed. It is found that the t
f of the single channel PSS (SCPSS) decreased significantly with increasing p, but hardly varied with U
A under moderate p. However, it is not a sound solution to increase the p excessively to reduce t
f. Besides, increasing the number of cathode holes can obtain a shorter t
f at low pressures (which implies superior repetition frequency performance). However, at 25 Pa, the jitter (which is defined as the standard deviation of t
f in multiple tests) of the 2-channel PSS is larger than that of the SCPSS. And the jitter of the 4-channel and 8-channel PSS is also greater than 6 ns and 2 ns, respectively. Through experimental and simulation analyses, it can be explained as the stepwise penetration of the virtual anode and the non-simultaneous ignition of the channels. A scheme to increase the trigger energy (ϵ) has been adopted to improve the simultaneous ignition probability, while shortening t
f and reducing jitter. After optimization, the good ignition probability of the 4-channel PSS has been improved to 82% and the jitter has been reduced to less than 1 ns at 25 Pa and 14.7 mJ.

Published: September 2024

Abstract
Telecommunication of the next generation demands filters that can operate in the 10 GHz range with sufficient bandwidths. For surface-acoustic-wave (SAW) devices this prerequisite translates into high sound velocities and high piezoelectric couplings. Wurtzite AlN on diamond, which exploits the strong piezoelectricity of AlN with the very high SAW velocity of diamond, has been considered a promising platform. A significant boost (up to a factor of 4) of the piezoelectric response can be obtained by alloying AlN with Sc. Here, the main challenge lies in the synthesis of highly-oriented thin (Sc,Al)N films on diamond. In this work, we aim at establishing a platform for SAW devices using plasma-assisted molecular beam epitaxy for the deposition of Sc0.2Al0.8N on diamond. We investigate the structural properties related to SAW generation gearing towards applications at high frequencies. To this end, we prepare (Sc,Al)N thin films on polished polycrystalline diamond wafers and demonstrate the efficient generation of SAW modes with frequencies up to 8 GHz. Systematic studies of the dependence of the SAW velocity and electromechanical coupling coefficient on the Sc0.2Al0.8N film thickness is presented for various SAW modes. Our result demonstrates the potential of this material combination for future application that requires large bandwidth in the ultra-high frequency range.
Coexistence of multiple magnetic interactions in oxygen-deficient V2O5 nanoparticles

Published: September 2024

Abstract
This paper reports on the spin glass-like coexistence of competing magnetic orders in oxygen-deficient V2O5 nanoparticles having a broad size distribution. X-ray photoelectron spectroscopy yields the surface chemical stoichiometry of nearly V2O4.65 due to significant surface defect density. Temperature-dependent electrical conductivity and thermopower measurements demonstrate a polaronic conduction mechanism with a hopping energy of about 0.112 eV. The V2O5−δ
sample exhibits strong field as well as temperature-dependent magnetic behaviour when measured with a superconducting quantum interference device magnetometer, showing positive magnetic susceptibility across the temperature range of 2–350 K. Field-cooled and zero-field-cooled data indicate hysteresis, suggesting glassy behaviour. The formation of small polarons due to oxygen vacancy defects, compensated by V4+ charge defects, results in magneto-electronic phase separation (MEPS) and various magnetic exchanges, as predicted by first-principle calculations. This is evidenced by the strong hybridisation of V orbitals in the vicinity of vacant oxygen site. An increase in V4+ defects shows an antiferromagnetic (AFM) component in calculations. The magnetic diversity in undoped V2O4.9 originates from defect density and their random distribution, leading to MEPS. This involves localised spins in polarons and their ferromagnetic (FM) clusters on a paramagnetic (PM) background, while V4+ dimers induce AFM interactions. Electron paramagnetic resonance spectra measured at different temperatures indicate a dominant PM signal at a g-value of 1.97 due to oxygen defects, with a broad FM resonance-like hump. Both signals diminish with increasing temperature. Neutron diffraction (ND) data rules out long-range magnetic ordering, reflecting the composition as V2O4.886. Despite the FM hysteresis, no long-range order is observed in ND data, consistent with the polaron cluster-like FM with MEPS nature. This detailed study shall advance the understanding of the diverse magnetic behaviour observed in undoped non-magnetic systems.

Published: September 2024

Abstract
This paper presents the development of a novel multiwavelength Twyman–Green interferometer for gauge block (GB) calibration. In this work, a novel gauge block interferometer (GBI) for both short- and long-gauge block calibration at the SASO-NMCC was designed, built, tested, and described. The interferometer features an optomechanical modulation-based proprietary evaluation system, and the final length value was determined by applying Edlén’s equation to the refractive index of air. The developed interferometric system comprises two setups: one for short GB calibration, and the other for long GB calibration. The first short (GBI) setup utilizes two stabilized lasers, green and red, in vertical-mode operation. Another long GBI utilizes three stabilized lasers in the horizontal mode of operation. The primary characteristics of the interferometric system are explained. An uncertainty analysis with a careful study of the main components, such as wavelength standards, fringe fraction, temperature corrections, refractive index correction, obliquity correction, phase correction, block geometry correction, wavefront correction, and wringing correction, is presented. With interferometry, measurement method (ISO 3650 and ASME B89.1), using our described highly-precision horizontal mode system (GBI), we could achieve uncertainty level of ‘Q[49;0,28 l]nm l (mm)’ (k = 2) in the measurement range ‘125–1000 (mm)’. For the other system(GBI) for short gauge blocks, the associated uncertainty is ‘Q[30;0,27 l]nm l(mm)’ (k = 2) in the range of ‘0.5–100 (mm)’.
Underground concrete pipe crack damage monitoring by the fuzzy analysis of microseism
Authors: Tao Kai , Jiang Yaoxin 
Published: September 2024

Abstract
Underground concrete pipes are critical for the safety of urban infrastructure. Cracks could lead to accidents such as fluid spillage and ground subsidence, as well as waterlogging. Thus, it is of great significance to measure and monitor the crack of pipeline. In this study, a fuzzy monitoring method for concrete pipe crack damage based on the microseism signal Gaussian Mixed Model (GMM) analysis was proposed. First, the multiple parameters of the microseism signal were extracted. Then, Criteria Importance Through Intercriteria Correlation (CRITIC) weight vector was constructed using the importance information of parameters. Furthermore, the GMM membership matrix was created by the similarity of the probability density distribution. The crack condition was assessed by means of a fuzzy calculation between the weight vector and membership matrix. The experiment indicated that the proposed method can monitor and assess the different crack conditions in real time.

Abstract
The analysis of wear based on on-line visual ferrograph provides crucial insights for the analysis of wear faults in mechanical equipment.However, online ferrograph analysis has been greatly limited by the low imaging quality and recognition accuracy of particle chains and high hubbles when analyzing lubricant oils in practical applications. To address this issue,this paper proposes an enhanced OLVF wear image detection model based on YOLOv8 and applies it to the multi-class intelligent recognition of ferrograph images .The cascade group attention module is introduced to enhance the diversity of features and improve computational efficiency. The attentional scale sequence fusion module is introduced to achieve precise and rapid recognition of small targets. This diverse branch block module is introduced efficiently to extracts features without compromising reasoning speed during training. For verification, a test of the bridge transmission box was conducted based on OLVF and 992 ferrograph images were collected. Experimental results reveal that the improved algorithm achieves an accuracy of 94.53% on the dataset of bridge transmission box ferrograph wear debris images collected through OLVF. This represents a 5.2% increase in recognition accuracy compared to the original algorithm while maintaining a processing time of only 0.69 ms per image. These findings provide compelling evidence for significant enhancements in both recognition accuracy and processing speed achieved by the improved algorithm, thereby establishing its considerable value for engineering applications.

Published: September 2024

Abstract
The hole is a significant mechanical structure type. In this paper, two visual measurement models are established for chamfered and non-chamfered holes. A concentric cylinder with a known diameter is used as a calibration object to obtain the external parameters corresponding to the end face of the measured hole. This approach overcomes limitations associated with using calibration plates for external parameter calibration and aligns better with requirements in production sites. By utilizing the obtained external parameters, three-dimensional coordinates of edge points on the measured hole can be determined, and an ellipse fitting algorithm is employed to obtain aperture and center point coordinates. In the experiment, gearbox housing is used to measure hole diameter and center-to-center distance. The measurements are compared with a coordinate measuring machine, demonstrating a measurement accuracy up to 0.1 mm. The experimental results confirm both feasibility and effectiveness of measurement model while maintaining low operational complexity.
The linear swept sine method to determine the dispersion curve of structural pavement
Authors: Handayani Gunawan , Mabruri Hafidz 
Published: September 2024

Abstract
Pavement evaluation must be performed in nondestructive ways. This includes using the multichannel analysis of surface waves method by recording waves detected by multiple sensors from one active source. However, heavy traffic produces noise and reduces the detection quality as the sensor moves further away from the measurement source. We need a pavement evaluation method that is immune to noise. The linear swept-sine method presented in this paper has a very high resistance to noise by using a wide frequency band vibration source to the ground received by a single accelerometer at a small distance. The noise resistance is obtained by applying a tracking filter at the receiver (accelerometer), which accepts the signal with the frequency swept linearly at the same rate as the transmitter. This tracking filter has a low-frequency component equal to the phase delay between the source and the receiver, even when the transmitted source is generated in the high-frequency range. The dispersion curve is calculated and inverted by using the surface wave inversion method to obtain the velocity model below the pavement by calculating the delay for each data segment.

complexes in the donor–acceptor–donor (DAD) configuration can provide ionization energies similar to phosphorus-doped diamond. All other complexes provide deep impurity levels. For the DAD configuration, the adsorption process on the diamond surface has been studied to demonstrate the feasibility of growing diamonds containing N-Ga-N in experiments. The desired complex configuration is not uniquely present in the co-doped system. Investigating these properties of different complexes beyond NGaN provides insight into the N and Ga codoped diamond system, yielding a more comprehensive understanding of its potential and limitations. Our research ideas can also be extended to other co-doped systems and help to evaluate other potential co-dopants for diamond.
Heat transport in SiCOH thin films: an experimental and molecular dynamics study
Authors: He Hu 
Published: September 2024

Abstract
Carbon-doped silicon dioxide (SiCOH) film is currently regarded as one of the most promising low-k materials in the integrated circuits (ICs) industry for advanced technology nodes. However, there have been limited studies on the thermal properties of SiCOH compared to its electrical and mechanical properties. In this study, we investigate the thermal conductivity of SiCOH thin films through molecular dynamics simulations (MD) and experimental characterizations. Our findings indicate that the size effect on thermal conductivity at 300 K is negligible when the thickness of SiCOH film is less than 20 nm. Additionally, we observe a contrasting temperature dependence law for the thermal conductivity of SiCOH thin films compared to crystal SiO2 thin films. Furthermore, we demonstrate a significant decrease in thermal conductivity with increasing porosity in SiCOH films; specifically, an increase in porosity from 5.35% to 42.77% results in a 60% reduction in thermal conductivity. Moreover, we validate our simulation results by characterizing the thermal conductivity of SiCOH using 3
