Published: November 2024

Abstract
Mexico is one of the major exporters of a variety of berries worldwide. Thrips (Thysanoptera) are highly attracted to berry crops, and several species can become serious pests that limit berry yield. Given the pest status of thrips in berry production and the magnitude and importance of berries for export in Mexico, this study was conducted to survey and identify the thrips fauna associated with commercial berry orchards in Mexico. We sampled berry plants in 41 commercial plantations of blackberry (Rubus spp.), blueberry (Vaccinium spp.), raspberry (Rubus spp.), and strawberry (Fragaria × ananasa) in Guanajuato, Jalisco, Michoacán, and Sinaloa during spring and summer 2020. Our study collected 4,394 thrips specimens belonging to 19 species of thrips. Of those, 53.7% were collected from blackberry, 16.1% from blueberry, 15.5% from strawberry, and 14.8% from raspberry. The predominant species in the four berry crops was Frankliniella occidentalis (Pergande). Its relative abundance with respect to other species of thrips collected was 52.9% in blueberry, 69% in raspberry, 79.6% in blackberry, and 88.7% in strawberry. The second most abundant species was Scirtothrips dorsalis Hood, varying from 2.6% in strawberry to 24.6% in blueberry. Other important phytophagous species recorded were Frankliniella cephalica (Crawford) and Frankliniella gossypiana Hood. These four species are invasive, polyphagous, and widespread in Mexico; thus, economic damage by one or more of these species can be expected in locales where management measures are not appropriately applied to avoid economic losses. Data gathered in this survey, coupled with information provided by related studies conducted in Mexico, should serve as a basis for further research dealing with monitoring and management of thrips populations.
Examinando la relación entre la planeación y la urbanización periférica en Lima
Authors: Lambert Rita 
Published: November 2024

Con un enfoque en las particularidades de la urbanización en las laderas periféricas de Lima, este artículo presenta tres objeciones o contraargumentos a la manera en que comúnmente se cualifica a los asentamientos autoconstruidos. En primer lugar, desafía el enfoque de informalidad argumentando que esta perspectiva sitúa a los asentamientos humanos fuera de foco: por un lado, oculta el carácter híbrido de las condiciones implícitas en estos procesos de urbanización; por otro, los presenta como tangenciales a estructuras legales «formales», impidiendo una mejor comprensión de la relación entre la planeación y los procesos de urbanización «informales». A pesar de que muchas ciudades del Sur Global son construidas siguiendo este modelo de urbanización, no deja de percibirse como «por fuera de», «en transgresión de» o «como una falla de» la planeación. En segundo lugar, este artículo cuestiona la valoración de resultados indeseados, tales como la producción y la reproducción del riesgo, como ajenos a la planeación y como consecuencia de la ocupación arbitraria de la tierra y de la falta de conocimiento y de capacidades técnicas de los autoconstructores. En tercer lugar, esta investigación resiste la atribución exclusiva de responsabilidades a la población más desfavorecida por los llamados procesos «informales» de urbanización. En respuesta a estas objeciones, se propone una perspectiva relacional y sociomaterial para entender mejor la urbanización de las laderas.

Published: November 2024

This study aimed to examine the factors that classify teacher competencies, based on good and bad educator certificates. The method used in this research is discriminant analysis. This study used a questionnaire survey method. The sample in this study was 54 teachers of the Light Automotive Engineering Vocational High School. The findings of this study revealed several key points: first, there is a significant average difference between competent and non-competent teachers based on the factors evaluated. Second, a discriminant function model was developed from the data, which effectively distinguishes between teacher competencies. Lastly, the model demonstrated a high prediction accuracy, successfully classifying teachers as competent or non-competent with a high degree of reliability. Therefore, this discriminant model can be utilized to assess teacher competency effectively.

Comparison of Implant Placement Accuracy Between Manual, Robot-Assisted, Computer-Navigated, Augmented Reality Navigated, Patient-Specific Instrumentation, and Accelerometer Navigated Total Hip Arthroplasty
Authors: Miura Takanori , Yamamoto Norio , Shiroshita Akihiro , Tsuge Takahiro , Saitsu Akihiro , Yoshitani Junya , Nakao Shuri , Takami Ken 
Published: November 2024

Background:
Malpositioning of the acetabular cup during total hip arthroplasty (THA) can lead to complications. Robotic surgery and navigation techniques aim to address this issue, but there is limited evidence regarding which method can achieve better clinical outcomes. Therefore, this network meta-analysis (NMA) aimed to compare the efficacy of various navigation methods.

Methods:
This NMA of prospective randomized controlled trials compared robot-assisted systems (RAS), computer-assisted navigation systems (CAS), augmented reality-based portable navigation (AR), patient-specific instrumentation (PSI), portable accelerometer-based navigation (PN), and conventional methods (C) for THA procedures. We searched MEDLINE, EMBASE, Cochrane, Central Register of Controlled Trials, International Clinical Trials Platform Search Portal, and ClinicalTrials.gov. databases. The primary outcomes included revision surgery and postoperative clinical scores, and the secondary outcomes encompassed cup placement accuracy, acetabular cup placement outliers from the Lewinnek safe zone, surgical time, and complications. We used a Bayesian random-effects NMA, and confidence of evidence was assessed using confidence in NMA.

Results:
We identified 45 studies including 2,122 patients. We did not find large differences in revision surgery, clinical outcome scores, cup inclination, or anteversion angle accuracy among the modalities. AR, CAS, and PSI exhibited a lower risk of outliers from safe zones than C. In addition, RAS and CAS had a longer surgical time than C.

Conclusions:
Robotic and navigation tools did not reduce the revision risk or enhance clinical outcomes. AR, CAS, PSI, and PN may decrease the risk of cup placement outliers in safe zones. However, the cup placement accuracy was equivalent, and the surgical time may be longer in RAS and CAS than in C.

Published: November 2024

Abstract

Background: Mulberry silkworm is the only source of silk production, it feeds only on mulberry. Due to the climatic changes during the feeding period, thermal stress certainly affects silkworm vitality and, consequently, its production worldwide, it was important to select a strong hybrid that adapts to these changes so, the selection depended on its ability to tolerate rising temperature.
Results: The results of the research showed that when B. mori larvae were subjected to the heat for five hours at 40ºC, on the 2nd day of the fourth larval instar, the expression levels of the heat shock protein genes HSP-19.9 and HSP-20.8 gene increased (by 294 and 339%, respectively). Furthermore, the HSP-20.8 gene expression levels were significantly greater than the HSP-19.9 gene expression levels.
Conclusion: Recently, according to the climatic changes it was necessary to recommend silkworm strains that can change the heat shock protein genes to combat rising temperatures during the feeding period.
Non-extractable Residues (Ner) in Persistence Assessment – Effect on the Degradation Half-life of Chemicals
Authors: Jespersen Cindy , Trapp Stefan , Kästner Matthias 
Published: November 2024

Abstract

The ECHA guidance on persistence (P) assessment has been updated with respect to non-extractable residues (NER). Unless further characterized, total NER shall be considered as non-degraded parent compound. We investigated how different NER fractions affect degradation half-lives (DegT50) of chemicals and the P assessment. Total NER consists of the fractions sorbed/sequestered (NER I), covalently bound (NER II), and bioNER (incorporated into the biomass, NER III). NER I pose a risk due to potential release, NER II have much lower release potential, and bioNER do not have any.
Data from 46 degradation tests with 24 substances were analyzed to find DegT50 for four scenarios: i) extractable parent compound, ii) parent plus total NER, iii) parent plus xenoNER, and iv) parent plus NER I. The Microbial Turnover to Biomass (MTB) model was applied to calculate bioNER, and then xenoNER were calculated as total NER minus bioNER. The half-lives were determined by the fit program CAKE, using single first-order kinetics (SFO) for all fits.
We found increasing degradation half-lives for the scenarios: parent only < parent + NER I < parent + xenoNER < parent + total NER. A third of all chemicals show half-lives above the persistence criterion (120 days in OECD 307) for scenario i, and two thirds with scenario ii and, therefore, would be classified as 'persistent´. For two compounds, the subtraction of bioNER led to a change to 'not persistent´.
The inclusion of NER will thus have significant effects on the DegT50 of compounds and the persistence assessment. Experimental quantification of NER I (scenario iv) significantly reduces half-lives, in comparison to total NER (scenario ii). The results are closer to half-lives for parent only (scenario i) and give the lowest acceptable DegT50 below the vP criteria under the latest guidance. In addition, refining the DegT50 based on modelled bioNER can provide a relevant option for persistence assessment, without laborious and costly analyses for NER I determination, when considered in the regulatory assessment of persistence. Moreover, bioNER can also be calculated for existing test data.

Abstract

Variable stiffness electronics represent the forefront of adaptive technology, seamlessly integrating rigid and soft electronics in a single system through dynamic mechanical modulation. Gallium’s high modulus tuning ratio and rapid phase transitions make it ideal for such transformative electronic systems (TES), yet its liquid-state instability, high surface tension, and unintended phase transitions during processing pose significant challenges. Here, we introduce STiffness-Adjustable temperature-Responsive ink (STAR ink), a novel chemically sinterable gallium composite electronic ink designed to overcome these obstacles. STAR ink enables high-resolution (~ 50 µm) circuit patterning, large-scale batch fabrication, and three-dimensional structure coating at room temperature. TES created with STAR ink exhibit exceptional mechanical tunability (tuning ratio: 1465) and electrical conductivity (2.27 × 106 S·m− 1) through chemical-sintering, enabling them to change their shape and flexibility as needed. We showcase its versatility through multilayered variable stiffness printed circuit boards (PCBs) matching standard PCBs’ complexity and a neural probe softening at body temperature. These innovations underscore STAR ink’s potential to revolutionize reconfigurable electronics across consumer electronics, biomedical devices, and robotics.

Published: November 2024

Abstract

Extraction of polysaccharides from Rhodomyrtus tomentosa berry (RTP) is essential for understanding their bioactive ingredients and developing functional foods, nutraceuticals, and pharmaceuticals. This study aimed to evaluate the effects of ultrasonic-assisted enzymatic extraction (UAE) and microwave-assisted enzymatic extraction (MAE) on the yield, physicochemical properties, and antioxidant activity of (RTP). The single-factor and orthogonal experimental design revealed that the optimal conditions for ultrasound assisted RTP extraction are at liquid to solid ratio of 35 mL/g, ultrasonic time of 11 min, ultrasonic power of 240 W, and complex enzyme dose of 2.5% with RTP extraction yield of 35.67 ± 0.32%. FT-IR spectroscopy showed that UAE caused less disruption of the polysaccharide molecular structure and better retention of functional groups than MAE. The scanning electron microscopy results demonstrated that the ultrasonically treated samples exhibited a greater degree of structural disruption, which could more effectively facilitate the release of polysaccharides. In addition, RTP obtained by the UAE has a better extraction yield and ABTS radical scavenging activity than MAE. This study demonstrated that the UAE method is a promising method for extracting high-quality R. tomentosa berry polysaccharides based on its high yield, high efficiency, and outstanding antioxidant activity.
Deep Reinforcement Learning Combined with Transformer to Solve the Traveling Salesman Problem

Published: November 2024

Abstract

The Transformer model is widely employed to address the traveling salesman problem due to its robust global information acquisition, learning, and generalization capabilities. However, its high computational complexity and limited accuracy require further refinement. To overcome these shortcomings, a novel model is proposed, integrating a lightweight CNN embedding layer with a Transformer model enhanced by an efficient Pyramid Compressed Attention (PSA) mechanism. The introduction of the lightweight CNN embedding layer significantly reduces the number of parameters and computational complexity, allowing for the flexible extraction of local spatial features between neighboring nodes, while maintaining the ability to handle larger-scale datasets. The PSA mechanism, on one hand, improves solution accuracy by accounting for both local neighborhood relations and global dependencies. On the other hand, its multi-scale nature enables the model to adapt to problems of varying scales, ensuring strong performance for both small- and large-scale problems. Extensive experiments conducted on random datasets as well as the public TSPLIB dataset have demonstrated that the proposed model surpasses other deep reinforcement learning algorithms in terms of solution quality and generalization ability.

Abstract

This study examines the structure of the Lofoten Anticyclone, located in the Lofoten Basin of the Norwegian Sea. The high-resolution ROMS model is used for hydrodynamic modeling of the Lofoten Basin circulation. The dynamics of the Lofoten Vortex are investigated using the Lagrangian methods, where trajectories of passive tracers advected by the model velocity field are calculated, and Lagrangian indicators are computed for the studied region. Lagrangian markers initially located both in the core and on the periphery of the Lofoten Vortex are considered, showing different behaviors. Lagrangian markers in the core move along closed trajectories with angular velocities depending on their distance from the eddy's center. Those initially on the periphery form a series of S-shaped folds and twists, entering and exiting the eddy. We refer to this process as “eddy ventilation”. We demonstrated that particles leave the core and periphery of the eddy intermittently rather than uniformly over time, and the statistics of this process are analyzed. Additionally, it was found that the center of the Lofoten Vortex not only drifts cyclonically at an average speed of 3.8 cm/s but also oscillates in the horizontal plane, with the amplitude increasing in the eastern part of the Vortex’s movement area.

Abstract

Recently, considerable interest in Janus 2D materials has sparked various research investigations. Using density functional theory calculations, we study the atomic and electronic structure of six two-dimensional Janus GaInXO (X = S, Se, Te) materials to investigate their structural, vibrational, and piezoelectric properties. Their structural stability is evaluated through phonon calculations and molecular dynamics (MD) simulations at room temperature. The results show that OGaInTe is unstable, which is examined through crystal orbital Hamilton population (COHP) analysis. For the stable materials, Raman spectra are calculated for comparison with synthesis results. Furthermore, band structure calculations with spin-orbit coupling are performed for SGaInO, SeGaInO, and OGaInS with bandgaps to evaluate their potential applications. Finally, calculations for piezoelectric properties reveal that TeGaInO exhibits the highest piezoelectric coefficient, confirming its strong potential as a piezoelectric device.
