Study of growth twins and phase formation in CuNiAl alloys via a combinatorial approach
Authors: Alwen A. , Peter Nicolas J. , Schwaiger Ruth , Hodge A. M. 
Published: November 2024

AbstractIn this study, a combinatorial and high-throughput approach was leveraged to investigate nanotwin behavior in the ternary CuNiAl alloy system. Combinatorial co-sputtering was used to synthesize 169 unique CuNiAl alloy compositions, which were characterized in both the as-sputtered and annealed conditions to elucidate relationships between composition, nanotwin formation, and phase evolution. Compositional effects on phase formation were investigated using high-throughput X-ray diffraction, while scanning transmission electron microscopy was used to identify nanotwin compositional boundaries and isolate the roles of varied composition and nanotwin formation on microstructural evolution. It was determined that Al content was the primary variable influencing thermal evolution in the nanotwinned CuNiAl alloys, as it altered the thermodynamic driving forces by changing composition and reducing the as-sputtered twin boundary spacing. Overall, this work demonstrates a novel approach to globally study unexplored nanotwin synthesis domains beyond binary alloys.

The aim of this research is to analyze the experiences of seventh-grade students during the process of playing an educational mobile game that involves algebra topics and to reveal what they experience in such a learning environment, as part of a case study. Participants were nine seventh grade students who had low math achievement and spent a lot of time playing digital games. An educational digital game was developed regarding algebraic expressions and we asked students to play this game in their free times for two weeks. After practices with educational digital game for two weeks, semi-structured interviews were carried out with students. The collected data was analyzed qualitatively using the content analysis method. As a result, despite the technical challenges encountered by students in the game mechanics, they expressed overall satisfaction with the design of the game and the story employed in. The importance of game mechanics in the design of a mobile game was reaffirmed by the results obtained in this study.

Penilaian perkembangan pada anak pra sekolah sangatlah penting, mengingat masa pra-sekolah merupakan masa persiapan sebelum anak mendapat pendidikan formal ke tingkat Sekolah Dasar (SD). Apabila ditemukan kecurigaan penyimpangan dapat segera dilakukan stimulasi dan intervensi dini sebelum kelainan terjadi. Upaya pencegahan sedini mungkin perlu dilakukan untuk mengurangi masalah perkembangan dengan melakukan deteksi dini. Salah satu instrument yang bisa digunakan untuk mengukur perkembangan anak adalah Kuesioner Pra-Skrining Perkembangan (KPSP). KPSP merupakan instrumen yang berguna untuk mengetahui perkembangan anak normal atau anak mengalam penyimpangan. Dengan mengetahui sejak dini penyimpangan yang terjadi pada anak, maka orang tua bisa memberikan pengobatan atau intervensi sedini mungkin. Kegiatan pengabdian ini dilakukan selama 2 hari, yakni 2 – 3 Mei 2024. Sampel yang digunakan ialah anak dengan usia 4-6 tahun di TK Tawang 02 sebanyak 11 anak, instrumen yang dipakai pada pengabdian ini adalah KPSP. Hasil screening didapatkan bahwa 82% anak di TK Tawang 02 memepunyai tumbuh kembang normal namun terdapat pula 18% anak yang mengalami perkembangan yang meragukan. Dengan demikian, dapat disimpulkan bahwa anak prasekolah yang sedang bersekolah di TK Tawang 02 memiliki perkembangan yang sesuai dengan usianya.Kata Kunci: Perkembangan, Anak, Pra-sekolahDevelopmental assessment in pre-school children is very important, considering that the pre-school period is a preparatory period before children receive formal education to the elementary school level. If there is a suspicion of deviation, early stimulation and intervention can be done before abnormalities occur. Prevention efforts as early as possible need to be made to reduce developmental problems by conducting early detection. One of the instruments that can be used to measure child development is the Developmental Pre-Screening Questionnaire (KPSP). KPSP is a useful instrument to determine the development of normal children or children experiencing deviations. The sample used was children aged 4-6 years at TK Tawang 02 as many as 11 children, the instrument used in this service was KPSP. The screening results showed that 82% of children in Tawang 02 Kindergarten had normal growth and development but there were also 18% of children who experienced questionable development. Thus, it can be concluded that preschool children who are currently attending Tawang 02 Kindergarten have age-appropriate development.

A Continuous Multistage Fracing Technique
Authors: Webster K. R. , Goins W. C. , Berry S. C. 
Published: November 2024

Abstract
Wells with multiple producing zones can be fractured one zone at a time during continuous pumping with a high degree of probability of treating all zones by [1] perforating with charges designed to produce round, burr-free holes; [2] perforating the same low number of holes [usually eight] into each zone; [3] perforating in acid; and [4] using sealer balls between frac stages exactly matching in number the holes in each zone.
During field trials of the process, recovered fluid-cut sealer balls indicated that quite often jet perforated hol.es had poor roundness and ragged burrs preventing good seal. It was necessary to have jet charges and guns redesigned to provide consistently round and burr-free entrance holes. Perforating the same number of holes per zone eliminates the guesswork when determining the number of ball sealers to use per stage. Experience has shown that perforating in acid reduces breakdown pressures, allowing the process to be used in areas where previous fracing indicated the method could not be applied. Using sufficient holes per zone to handle the total pumping rate at a low differential pressure prevents breaking down more than one zone at a time. High differential pressure from too few holes consumes energy and adds to the cost of the treatment. A calculation procedure is used to determine the holes required per zone based on flow rates and total cross sectional area of the perforations.

Abstract

This study explored the effects of inoculation with different microbial sources (mature compost (MC) or commercial microbial agents (MA)) on the physicochemical properties and the structure and functional succession of microbial communities during sorghum straw (SS) composting. The results showed that the volatile solid (VS) degradation efficiency increased by 30.34% and 20.27% respectively by adding MC (M2) and MA (M3), from that without inoculation (M1). Both additives improved the seed germination index (GI) of the end products (M2: 142.43% > M3: 120.54% > M1: 107.79%). MC inoculation exhibited superior performance than MA inoculation, probably owing to the fast adaptation of MC to the SS composting environment. Microbial analysis showed that MC addition significantly enriched the core bacterial genera Thermobifida, Lysinibacillus, and unclassified_o__Bacillales related to VS degradation efficiency and GI and promoted the succession rate of microbial communities, consequently acceleratingthe composting process into the maturation stage. Co-occurrence network analysis demonstrated that MC inoculation bolstered synergistic relationships among the bacteria. Correlation analysis also indicated that the discrepancy in species and abundance of introduced functional bacteria was the main reason for the differences among the three treatments. These results provide useful information for strategies to promote SS composting and reveal the potential influence mechanism of exogenous inoculants on microbial community succession.

Abstract

Mining wire rope (MWR) is an important part of mine hoisting equipment and plays a key role in mining operations. Damage to these ropes can significantly reduce production efficiency and pose serious safety risks to workers. Therefore, quantitatively identifying damage in MWR is of great importance. Traditional methods for damage signal identification rely on manual feature extraction (MFE), which depends heavily on experience and lacks stability and flexibility. This paper proposes an end-to-end (E2E) quantitative identification model for MWR damage based on time series classification (TSC) and deep learning (DL). Unlike traditional methods, the E2E model learns features directly from the one-dimensional raw signals of MWR damage and does not require MFE. In order to test its validity and versatility, experiments were conducted on three different datasets. The results show that the E2E method performs well in quantitatively identifying MWR damage compared to other methods and this method meets the requirements of the mining industry in terms of precision and efficiency to ensure safe and reliable operation of mining work.

Abstract

This paper presents an experimental evaluation of the stability and performance of commercial quadrupedal robots, specifically the Ghost Robotics Vision 60 and Boston Dynamics Spot, under dynamic ground conditions typical of non-inertial naval environments. Our study systematically assesses these robots in controlled laboratory settings and real-world scenarios aboard the M80 Stiletto, a naval prototype vessel. The experiments simulate various sea wave conditions and ship motions to rigorously test the robots' stability, balance, and path-following capabilities.We analyze primary metrics including the distance of the center of mass to the support polygon boundary, body-position tracking accuracy, trunk orientation steadiness, and joint torque profiles under dynamic disturbances from ground accelerations. The results reveal that while both robots demonstrate operational capabilities, significant challenges remain. Vision 60, in particular, exhibits superior stability, balance, and lower peak torque when handling substantial ground motions compared to Spot.However, both robots struggle with accurate body-position tracking under aggressive ground motions, underscoring the need for advanced control strategies. These findings highlight the limitations of current commercial quadruped robots in operating on accelerating grounds and underscore the urgent requirement for further research and development in motion planning and control design.

Abstract

Background: Reliable data on whooping cough, a highly contagious disease sometimes fatal for infants, are largely lacking in low- and middle-income countries.
Methods: We conducted a hospital-based prospective study (PS) on infants, and a household contact-case investigation (CCI) for positive cases throughout Cambodia and in the city of Antananarivo, Madagascar, between 2017 and 2019. The PS, in which
Bordetella diagnostics (qPCR) were performed, included infants aged ≤6 months presenting with ≥5 days of cough associated with one pertussis-like symptom. CCI was performed using qPCR and serology regardless of clinical signs.
Results: In this study, 207 and 173 participants from Cambodia and Antananarivo were respectively enrolled. Respectively 26.1% (54/207) and 22.0% (38/173) of the infants were infected in the cohorts from Cambodia and Antananarivo. Cough longer than 10 days appeared as a risk factor in both countries, as well as coughing spells, apnea and normal pulmonary auscultation, having a coughing contact in Cambodia. In Antananarivo, good condition between cough appeared as a risk factor. Five infants, all positive, died during the study. In Cambodia and Antananarivo respectively, 50.9% (118/232) and 67.8% (82/121) of the contact cases were positive. Respectively 94.4% (51/54) and 90.3% (28/31) of the households had at least one positive contact case.
Conclusion: The data show that pertussis circulates at high levels among infants and in their households both in Cambodia and in Antananarivo. Given the vulnerability of youngest infants, who are too young to receive fully primary vaccination, they need to be protected through boosters breaking transmission chains. Molecular diagnosis, as well as trained medical human resources to detect the disease early, are absolutely key to protect populations.

Published: November 2024

Abstract

Background
Puccinia striiformis f. sp. tritici (Pst) causes wheat stripe (yellow) rust disease, which is one of the most destructive diseases affecting wheat worldwide. ATPases, a class of membrane proteins, play an important role in material exchange and signal transduction both within and outside biological cells by transporting ions and phospholipids. In plant pathogens, P-type ATPases primarily participate in pathogen development and virulence regulation. However, the P-type ATPase of subfamily IIIA (PMA) has not yet been identified in Pst. To investigate the potential functions of the PMA gene family in Pst, we conducted a genome-wide bioinformatics analysis and examined the expression profiles of the PMA gene family.
Results
Six PMA genes were identified in the genome of Puccinia striiformis f. sp. tritici (CYR34 race). The PMA proteins encoded by these genes ranged in length from 811 to 960 amino acids. Each of the six PMA genes contained a typical ATPase IIIA H superfamily domain and was distributed across four chromosomes. Thirty-six major cis-regulatory elements were detected within the PMA gene family members. Elements such as the CGTCA-motif and TGACG-motif play significant roles in responding to environmental stresses and hormone signals. Quantitative PCR analysis revealed that the expression of the PMA04 gene was generally higher at 9°C under various temperature stresses. The PMA06 gene typically exhibited higher expression levels at 16°C. During the infection of Pst, the expression levels of PMA04, PMA05, and PMA06 were elevated at 72 hours post treatment.
Conclusions
The P-type ATPase IIIA gene family in the CYR34 strain contains six PMA genes, and they play a crucial role in responding to temperature stress and pathogen infection, exhibiting a distinct splicing pattern.

Abstract

A time-traveling is generated and experimentally confirmed using a relativistic circle constructed by a microstrip add-drop multiplexer. Such a device can operate with both an antenna and electronic device functions, which can be applied to link the two different time events with wired or wireless transmission schemes. A timeline is formed by the Rabi frequency oscillation when entangled states under successive filtering. In this letter, the message can be modulated for the lower and upper sidebands of the Rabi frequency, presenting the past and future traveling times, respectively. The required information can be retrieved in the past or the future via point-to-point transmission terminals. In the experiment, the message is modulated by the required information to the frequency-time function of the present carrier and input into the system performed by a point-to-point link. The merging information is formed on the timeline, and can be retrieved via the device output ports. The band pass filter is applied to obtain the required message. The results have shown that the proposed work can be realized with point-to-point communication, where the collapsed entangled pairs from both sides of the worlds are merged then Bob can communicate with Alice via the timeline.

Abstract

Due to the differences in paleofire combustion patterns, the sources of biomass burning remains uncertain. This study examines the sediments from the Lubei Plain in the Shandong Peninsula, Lower Yellow River, integrating black carbon analysis and polycyclic aromatic hydrocarbons (PAHs) to reveal the evolution of fire ecology and human activities in this region over the past 5000 years. During the mid-to-late Holocene (5000 − 3500 year BP), the findings reveal that biomass burning levels in this region were generally low. However, between 3500 and 3000 year BP, smoldering biomass combustion pattern was prevalent, driven by extensive deforestation and prolonged droughts during the Shang Dynasty (3600 − 3046 year BP). During the late Holocene. three intensified-fire episodes (2600 − 2400 year BP, 2100 − 1900 year BP, and 1600 − 1400 year BP) may be a consequence of the population growth, deforestation to reclaim land, and/or the frequent wars during the periods of the Spring and Autumn & Warring States, Eastern Han, Wei, Jin, Southern & Northern Dynasties in China with cold and dry climatic condition. Conversely, two distinct periods of reduced fire activity are related to a significant decrease in anthropogenic biomass burning, likely due to population migration and farming activities decreased in the study area. Meanwhile, n-alkane and pollen records indicate a shift from primary forests to secondary artificial forests during the late Holocene, which were attributed to a decrease in the seasonal precipitation controlled by the weakening East Asian monsoon and increased anthropogenic biomass burning. In the past 300 years, the climate has become more arid, and the local biomass burning in this study area has increased significantly. According to principal component analysis, warfare was a potential factor in the high-intensity pyrogenic fires in the past 5000 years, and the low-intensity fire pattern induced by long-term and frequent deforestation activities of human beings is an important factor that cannot be ignored, which leads to the decrease of vegetation and land degradation in this region.
