Published: December 2023

Trastuzumab is used to treat HER2-amplified metastatic gastric cancer; however, most patients become trastuzumab-resistant within a year. Knowledge of the mechanisms underlying trastuzumab resistance is required to overcome this limitation. Here, we aimed to elucidate this resistance mechanism using four trastuzumab-resistant (TR) cell lines and investigate the efficacy of HER2-targeted therapies to overcome treatment resistance. Each TR cell line had different phenotypic characteristics. Interestingly, HER2 expression remained as high as the parental cell lines in TR cell lines, suggesting that HER2-targeted agents were still useful. As expected, three tyrosine kinase inhibitors (lapatinib, neratinib, and tucatinib) and one antibody–drug conjugate (trastuzumab deruxtecan: T-DXd) exhibited good antitumor effects against TR cell lines. We further investigated the potential biological mechanism of T-DXd. When treated with trastuzumab or T-DXd, HER2 or its downstream signals were disrupted in parental cell lines, but not in TR cell lines. Moreover, T-DXd induced the expression of pH2A.X and cPARP and caused cell cycle arrest in the S or G2-M phase in TR cell lines. T-DXd showed promising antitumor activity in both parental and TR cell lines, suggesting that it is a potential candidate for overcoming trastuzumab resistance.

Published: December 2023

The accurate prediction of air pollutants, particularly Particulate Matter (PM), is critical to support effective and persuasive air quality management. Numerous variables influence the prediction of PM, and it's crucial to combine the most relevant input variables to ensure the most dependable predictions. This study aims to address this issue by utilizing correlation coefficients to select the most pertinent input and output variables for an air pollution model. In this work, PM2.5 concentration is estimated by employing concentrations of sulfur dioxide, nitrogen dioxide, and PM10 found in the air through the application of Artificial Neural Networks (ANNs). The proposed approach involves the comparison of three ANN models: one trained with the Levenberg–Marquardt algorithm (LM-ANN), another with the Bayesian Regularization algorithm (BR-ANN), and a third with the Scaled Conjugate Gradient algorithm (SCG-ANN). The findings revealed that the LM-ANN model outperforms the other two models and even surpasses the Multiple Linear Regression method. The LM-ANN model yields a higher R2 value of 0.8164 and a lower RMSE value of 9.5223.

Knowledge about the epidemiology of hepatitis D virus (HDV) is essential for effective screening and management. Our study aimed to update the prevalence of HDV infection among patients with hepatitis B virus (HBV) infection at hepatology clinics in Thailand. We enrolled HBV-infected patients from hepatology clinics at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, between June 2022 and November 2023. Demographic, biochemical characteristics, and liver-related complications (LRC), including cirrhosis and hepatocellular carcinoma, were reviewed. The competitive enzyme and chemiluminescence immunoassays were used to detect anti-HDV antibodies. Real-time polymerase chain reaction (RT-PCR) was used to test for HDV RNA in anti-HDV-positive patients. The HDV genotype was identified in detectable HDV RNA samples. Of the 702 enrolled patients, four (0.6%) had positive and equivocal for both anti-HDV tests. Two (50.0%) of the four patients tested positive for HDV RNA and genotype 1 was identified; one had multiple risk factors. Anti-HDV seroprevalence was not significantly different between patients with and without LRC. In conclusion, HDV co-infection is less common in Thailand than globally. Additionally, our study identified genotype 1, the predominant HDV genotype worldwide, and observed co-infection even without LRC.

Published: December 2023

Rapid global urbanization has made environmental amenities scarce despite their considerable advantages, ranging from aesthetics to health benefits. Street greenness is a key urban environmental amenity. This study developed a green index as an objective measure of greenness using street view images and assessed its predictive power along with that of other environmental amenities for metropolitan housing prices. Spatial interpolation was used to transform point data into areal data, enabling effective analysis of a dataset covering an entire metropolis. A series of hedonic models revealed that (1) street greenness is significantly and negatively associated with housing prices, (2) a traditional greenness indicator and the green index provide complementary information, indicating that they could be used for different purposes, and (3) environmental amenities, in general, demonstrated significant relationships with housing prices. Our analysis strategy including spatial interpolation can be widely employed for studies using different types of data. The findings demonstrating a complementary relationship between our two greenness indicators provide valuable insights for policymakers and urban planners to improve street-level greenness and green accessibility. Considering the significance of environmental amenities, this study provides practical approaches for executing sustainable and healthy city development.

Amorphophallus konjac, belonging to the genus Amorphophallus of the Araceae family, is an economically important crop widely used in health products and biomaterials. In the present work, we performed the whole-genome assembly of A. konjac based on the NovaSeq platform sequence data. The final genome assembly was 4.58 Gb with a scaffold N50 of 3212 bp. The genome includes 39,421 protein-coding genes, and 71.75% of the assemblies were repetitive sequences. Comparative genomic analysis showed 1647 gene families have expanded and 2685 contracted in the A. konjac genome. Likewise, genome evolution analysis indicated that A. konjac underwent whole-genome duplication, possibly contributing to the expansion of certain gene families. Furthermore, we identified many candidate genes involved in the tuber formation and development, cellulose and lignification synthesis. The genome of A. konjac obtained in this work provides a valuable resource for the further study of the genetics, genomics, and breeding of this economically important crop, as well as for evolutionary studies of Araceae family.
CFD modeling and simulation of benzyl alcohol oxidation coupled with hydrogen production in a continuous-flow photoelectrochemical reactor
Authors: Hanamorn Thorfhan , Vas-Umnuay Paravee
Published: December 2023

Various conversion routes of biomass and its derivative compounds into high-value products has attracted attention from researchers recently. Among these, a solar-driven photoelectrochemical (PEC) oxidation approach of biomass alcohols to aldehydes is particularly of great interest for the potential applications because the reaction is selective and simultaneously accompanied with hydrogen production. Here, we propose a simulation of selective oxidation of benzyl alcohol into benzaldehyde coupled with hydrogen production in a 2-dimensional continuous-flow PEC reactor using COMSOL Multiphysics (5.6). In order to develop and fabricate a simple yet efficient reactor for a practical use, it is crucial to investigate the effects of operating and design parameters of the reactor on the reactions. Our studies demonstrated that the main contributions to product formation were the electrolyte flow velocity and the width of electrolyte channels. The optimized design parameter exhibited good photoelectrochemical performance with uniform potential distribution within the channels which served diffusion of neutral and charged species and electrochemical reaction. The maximum conversion of benzyl alcohol in this work was 48.25% with 100% selectivity of benzaldehyde. These findings are key for the design of the continuous-flow PEC reactor that can be applied to any series of biomass conversion reactions under mild conditions.
Parasitoid-induced changes in metabolic rate and feeding activity of the emerald ash borer (Coleoptera: Buprestidae): implications for biological control
Authors: Dang Ying-Qiao , Duan Jian J. , Li Andrew Y.
Published: December 2023

Parasitoid-host interactions form the foundation of biological control strategies against many agriculture and forest insect pests. The emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), is a serious invasive pest of ash (Fraxinus spp.) trees in North America. Tetrastichus planipennisi (Hymenoptera: Eulophidae) is a gregarious, koinobiont endoparasitoid, attacking late (3rd to 4th) instars of EAB larvae, which feed in the live phloem of ash trunks or branches, making serpentine-like galleries filled with larval frass. In the present study, we tested the hypothesis that T. planipennisi regulates the host metabolism and feeding activity to optimize its offspring development and fitness. We first compared the respiration rate of parasitized and unparasitized host larvae at different times after parasitism, and then measured feeding activity of both parasitized and unparasitized host larvae inside their feeding galleries. Although parasitized host larvae increased metabolic rate and feeding activity in the first few days of parasitism, T. planipennisi parasitism induced an overall reduction of the metabolic rate and decrease in feeding activity of parasitized host larvae over their development period. In addition, there was a negative relationship between feeding activity of parasitized hosts and brood sizes of the parasitoid progeny—i.e., the more parasitoid progeny a host larva received, the less feeding activity the host had. These findings suggest that T. planipennisi has limited ability to optimize its offspring development and fitness through regulations of the host metabolism and feeding activity and its parasitism reduces feeding damage of parasitized EAB larvae to infested ash trees.

Published: December 2023

Universal newborn hearing screening (UNHS) and audiological diagnosis are crucial for children with congenital hearing loss (HL). The objective of this study was to analyze hearing screening techniques, audiological outcomes and risk factors among children referred from a UNHS program in Beijing. A retrospective analysis was performed in children who were referred to our hospital after failing UNHS during a 9-year period. A series of audiological diagnostic tests were administered to each case, to confirm and determine the type and degree of HL. Risk factors for HL were collected. Of 1839 cases, 53.0% were referred after only transient evoked otoacoustic emission (TEOAE) testing, 46.1% were screened by a combination of TEOAE and automatic auditory brainstem response (AABR) testing, and 1.0% were referred after only AABR testing. HL was confirmed in 55.7% of cases. Ears with screening results that led to referral experienced a more severe degree of HL than those with results that passed. Risk factors for HL were identified in 113 (6.1%) cases. The main risk factors included craniofacial anomalies (2.7%), length of stay in the neonatal intensive care unit longer than 5 days (2.4%) and birth weight less than 1500 g (0.8%). The statistical data showed that age (P < 0.001) and risk factors, including craniofacial anomalies (P < 0.001) and low birth weight (P = 0.048), were associated with the presence of HL. This study suggested that hearing screening plays an important role in the early detection of HL and that children with risk factors should be closely monitored.

Published: December 2023

This research examines the biological treatment of undiluted vegetable waste digestate conducted in a bubble column photobioreactor. Initially, the bioreactor containing 3N-BBM medium was inoculated with Microglena sp., Tetradesmus obliquus, and Desmodesmus subspicatus mixture with a density of 1.0 × 104 cells/mL and the consortium was cultivated for 30 days. Then, the bioreactor was semi-continuously fed with liquid digestate with hydraulic retention time (HRT) of 30 days, and the treatment process was continued for the next 15 weeks. The change in the microalgal and cyanobacterial species domination was measured in regular intervals using cell counting with droplet method on a microscope slide. At the end of the experiment, Desmonostoc sp. cyanobacteria (identified with 16S ribosomal RNA genetical analysis) as well as Tetradesmus obliquus green algae along with Rhodanobacteraceae and Planococcaceae bacteria (determined with V3–V4 16sRNA metagenomic studies) dominated the microbial community in the photobioreactor. The experiment demonstrated high treatment efficiency, since nitrogen and soluble COD were removed by 89.3 ± 0.5% and 91.2 ± 1.6%, respectively, whereas for phosphates, 72.8 ± 2.1% removal rate was achieved.

Kinase inhibitors (KIs) are important cancer drugs but often feature polypharmacology that is molecularly not understood. This disconnect is particularly apparent in cancer entities such as sarcomas for which the oncogenic drivers are often not clear. To investigate more systematically how the cellular proteotypes of sarcoma cells shape their response to molecularly targeted drugs, we profiled the proteomes and phosphoproteomes of 17 sarcoma cell lines and screened the same against 150 cancer drugs. The resulting 2550 phenotypic profiles revealed distinct drug responses and the cellular activity landscapes derived from deep (phospho)proteomes (9–10,000 proteins and 10–27,000 phosphorylation sites per cell line) enabled several lines of analysis. For instance, connecting the (phospho)proteomic data with drug responses revealed known and novel mechanisms of action (MoAs) of KIs and identified markers of drug sensitivity or resistance. All data is publicly accessible via an interactive web application that enables exploration of this rich molecular resource for a better understanding of active signalling pathways in sarcoma cells, identifying treatment response predictors and revealing novel MoA of clinical KIs.

Special Education Assessment: Practices That Support Eligibility and Intervention
Authors: Power-deFur Lissa A.
Published: December 2023

Purpose:

Federal special education requirements specify that information districts must gather and review during the process of finding a student eligible for special education and developing a student's Individualized Education Program (IEP). The purpose of this tutorial is to describe the federal requirements related to evaluation and assessment and to apply best practices in assessment to those expectations, thereby enhancing teams' ability to identify students' strengths and needs, determine eligibility for services, and create high-quality IEPs.

Method:

This tutorial includes a detailed review of the Individuals with Disabilities Education Act (IDEA) statute and regulations and the U.S. Department of Education guidance related to evaluation, assessment, and IEP development. The tutorial also reflects on an analysis of existing data regarding the identification of students with speech-language impairment in one state and a narrative review of the current literature related to assessment and its role in intervention planning.

Results:

The results indicate that the IDEA requires rigorous evaluation and assessment practices to determine eligibility (evaluation) and identify students' unique strengths and needs for intervention (assessment). By adhering to these requirements and employing evidence-based assessment practices, speech-language pathologists (SLPs) can be assured that they are gathering accurate and useful information. This information is fundamental to developing an IEP that will support students' acquisition of the knowledge and skills needed to progress in the general curriculum.

Conclusions:

This tutorial reviews federal requirements related to assessment and links these with best practices in assessment, to facilitate compliance with federal evaluation requirements and IEP development in a manner that meets the needs of all students. SLPs can rely on the IDEA for guidance in completing their special education evaluations and assessments, using this as a framework for employing evidence-based assessment practices.
Task offloading and resource allocation for blockchain‐enabled mobile edge computing
Authors: Fang Renbin , Lin Peng , Liu Yize , Liu Yan
Published: December 2023

Mobile edge computing (MEC) has risen as an effective approach to support ubiquitous and prosperous mobile applications. Due to the strict delay requirements and the increasingly complex application environments, the computation efficiency and security have become the bottleneck that restricts the MEC system. Here, a blockchain‐enabled task offloading scheme is proposed, where the sensitive computation tasks of user terminals (UTs) can be offloaded to a blockchain‐assisted base station (BS). The MEC‐assisted BS helps UTs compute tasks while the blockchain consensus protocol ensures the security of the task offloading and computing process. To manage the allocation of computing resources between task offloading and blockchain consensus, the task offloading and resource allocation are formulated as a joint optimization problem. The aim of the problem is to minimize the energy consumption of UTs while guaranteeing the delay requirement. By transforming the original problem into a Markov decision process, a collective reinforcement learning algorithm is proposed to solve the problem in an online fashion. In the simulations, the convergence and the performance of the proposed scheme are evaluated. The simulation results show the effectiveness of the scheme.
An efficient optimization framework for distribution network planning by simultaneous allocation of photovoltaic distributed generations and transformers
Authors: Alipour Mohammad Ali , Askarzadeh Alireza
Published: December 2023

Among the distribution network planning problems, allocation of transformers is one of the most important and challenging ones. On the other hand, owing to the widespread growth of distributed generations (DGs), their inclusion in the planning problems is vital. This paper proposes an efficient optimization framework for simultaneous allocation of photovoltaic (PV) systems and service transformers in the distribution network. For this aim, to improve the network performance, location and size of the transformers and PV units are optimally determined. Due to the difficulty of the planning problem, four variants of crow search algorithm (CSA) including original CSA, differential CSA (CSAd), directed differential CSA (CSAdd) and chaotic directed differential CSA (CSAcdd) are introduced and applied to the planning problem. To evaluate the impact of PV cost on the results, the planning problem is solved considering different PV system costs. Simulation results show that at the price of $1.25/W, installation of PV systems is cost‐effective, so that over the case study, 400 kW PV system was installed. By decreasing the PV price to $1.2/W, the maximum capacity considered for a PV system is installed. Moreover, on average, CSAd produces more accurate and robust results than the other studied algorithms.

This study aimed to determine the success of artificial insemination (AI) using unsexed and sexed frozen semen with albumin sedimentation. This research was conducted from August to December 2022 at a farmer community in Pandesari Village, Pujon District, Malang Regency. The material used in this study was 78 heads of Friesian Holstein cattle, with the criteria of having a minimum body condition score of 2.5 (scale of 1–5), having normal reproductive organs, and showing signs of estrus. 38 cows were used as acceptors in artificial insemination (AI) with unsexed frozen semen, and 38 cows in AI with albumin sedimentation frozen semen. The variables used are non-return rate 1, non-return rate 2, and conception rate. The data obtained were then analyzed descriptively. The results showed that the percentage values of NRR1, NRR2, and CR in AI using frozen semen unsexed were 76.3%, 63.1%, and 47.3%, respectively, while the percentage values of NRR1, NRR2, and CR in AI using frozen semen sexed were 94.7%, 86.15%, and 63.15%. Based on the study's results, insemination success using albumin sedimentation frozen semen sexed showed better results than AI using unsexed semen.

Published: December 2023

The aim of that study was to evaluate the effectiveness and suitability of its use according to local conditions and ensure compliance with applicable food safety standards. A raw database had been constructed based on peer-reviewed and published research articles that reported the use of ozonation time on the internal quality of milk. The results of the observations were data collected using Microsoft Excel, followed by using Microsoft Word for formula processing before processing the data using the SAS application. That research used meta-analysis techniques to integrate 29 pieces of data from six pieces of literature that observed and researched the effects of the length of time of the ozonation process on milk quality. The variables observed were the effect of the long ozonation process for dairy products on the number of bacteria, protein levels, aflatoxin levels, and pH. The results of observing the effect of long ozonation on milk to determine the number of bacteria had an insignificant effect (p > 0.05). The protein results had a significant effect (p > 0.05) on the duration of ozonation; the results of aflatoxin levels found in milk had a significant effect (p > 0.05) on the duration of ozonation in milk; and the pH of milk also had a significant effect (p > 0.05) on the duration of ozonation in milk. In summary, using ozonation time was safe for the internal quality of milk.

This research aims to obtain uniform Apis mellifera queen bees, both in terms of age and morphometrics, which will be developed into colonies to evaluate quality and identify bee forage plant species in grazing areas. The study was conducted in two different locations: Sukorame Village, Tumpang Subdistrict, Malang Regency, and Pajaran Village, Poncokusumo Subdistrict, Malang Regency. Pollen sample analysis was carried out at the Genetech Saraswanti Indo Surabaya Laboratory. The research method involved field observations and direct experiments, focusing on the research locations and grafting techniques. Data collected included both primary and secondary data, and data analysis was performed using unpaired t-tests to compare data from the two different research locations. The research results indicate that the difference in location has no significant effect (P>0.05) on the Apis mellifera queen bee production using the grafting method in terms of the measured morphological variables. The average abdomen length in Sukorame and Pajaran locations was 9.08±1.65 mm and 9.11±1.37 mm, respectively. The average abdomen width in Sukorame and Pajaran locations was 4.99±0.41 mm and 4.96±0.36 mm, respectively. The average abdomen height in Sukorame and Pajaran locations was 4.18±0.51 mm and 4.35±0.57 mm, respectively. The difference in location with the grafting method also had no significant effect (P>0.05) on the proboscis length, with average values of 1.30±0.39 mm for Sukorame and 1.45±0.43 mm for Pajaran locations. The use of different locations in the production of Apis mellifera queen bees using the grafting method provides consistent performance in terms of abdomen length, abdomen width, abdomen height, and proboscis length.

Depuis la fin des années 2000, des projets d’observatoires se multiplient pour tenter de suivre, de quantifier et de documenter les grandes acquisitions foncières. À partir de l’expérience de quatre observatoires qui se sont investis sur le thème des grandes acquisitions foncières en Afrique (au Cameroun, à Madagascar, en Ouganda et au Sénégal), l’article analyse les choix stratégiques faits en termes de production et de partage des données par les parties prenantes des observatoires. Il met en évidence les compromis sur la diversité et le nombre de transactions étudiées, le nombre d’indicateurs de suivi, le niveau de recoupement des données et leur modalité et temporalité de publication. L’article étudie et illustre les difficultés socio-politiques de production et de publication des données, particulièrement saillantes dans le cas des acquisitions foncières. Il conclut sur l’importance pour les parties prenantes des observatoires d’opérer un ensemble de choix liés aux besoins d’usagers cibles, aux réalités de terrain, et enfin aux capacités de l’équipe de l’observatoire à produire des données et à jouer un rôle de médiation en direction des différents acteurs du foncier.

Mission profile concept for PV modules: use case – middle east deserts vs temperate European climate
Authors: Jaeckel Bengt , Daßler David , Pander Matthias , John Jim Joseph , Kumar Sagarika , Adothu Baloji
Published: December 2023

The paper addresses the need to simplify the comparison between different climatic conditions. Therefore, the concept of Mission Profiles is introduced to PV. Mission Profiles are a set of climatic stresses compiled to allow direct comparisons such as temperature, humidity, and UV exposure. The use-case in this paper is a comparison of a temperate with a hot climate. The results show that temperature driven processes are highly accelerated for the hot climate, whereas processes that involve humidity may lead to a similar annual degradation. The impact of light, particularly UV, is even more complex. UV triggered reaction processes can be photon absorption triggered and accelerated by temperature. However, for most observed interactions and material changes UV light goes in conjunction with moisture (H2O) for the chemical reaction and is accelerated by temperature. Calculating the impact of temperature and UV is possible. However, the impact of moisture is almost impossible as it requires the knowledge of the local microclimate. Only a “worst-case” scenario can be assumed while using ambient relative humidity for most events of the day, that, however, do typically not include condensation. With the introduction of Mission Profiles, it should be possible to assess stress more easily for particular sites in general. Differences in mounting such as open rack compared to e.g., BiPV can also better addressed, however, with some assumption to define the microclimate (e.g., exclude rear side cooling).
Experimental study of both bending moment and preload effect on the stress cycle upon bolts in a tee-stub

Published: December 2023

The experimental study exposed in this paper aims to exhibit the effect of the bending moment and the preload on bolts. A bolted tee-stub connection defined in Eurocode 3, part-1–8, is used. The flanges of the tee-stubs are taken from IPE400 and HEB 320 beams. The HR-M12-10.9 bolts are used and are equipped with four strain gauges each. The strains measured lead to calculate the axial load and the bending moment in the bolts. Six different configurations of the tee-stub are tested. For each configuration, four preload values have been studied. These tests provided an opportunity to take a critical look at the true value of the axial force and the bending moment in the bolt. We noted the existence of out-of-plane bending moment. Despite the existence of out-of-plane bending, it was seen through the results that the increase in the preload value causes a reduction in the amplitude of the stress cycle on the bolt. The percentages of the reduction due to the preload are greater for rigid flanges and smaller for flexible ones. As the amplitude of the stress is the main fatigue failure factor, its reduction shows that preload is beneficial for the fatigue resistance of such joints.
Research on thermodynamic characteristics of metallurgical slag
Authors: Guo Yongchun , Li Mengyao
Published: December 2023

This article uses Sn as the metal flux and CaF2-CaO as the reference slag to experimentally measure the activity of CaO at T = 1773∼1873 K. The effects of different w(Al2O3) and temperature(T) on CaO activity were investigated. The results are as follows: when w(MgO) = 6%, R(w(CaO)/w(SiO2)) = 1.20, w(Al2O3) = 12%, 14%, 16% and 18%, with the increase of w(Al2O3), the activity and activity coefficient of CaO in slag gradually decrease; with the increase of temperature (T), the activity and activity coefficient of CaO in slag gradually increase; the activity coefficient of Ca in Sn decrease with increasing temperature.
Some recent advances on the method of moments in kinetic theory
Authors: Pichard Teddy
Published: December 2023

This review presents some recent works on the construction of closure relations for moment systems extracted from a kinetic equation. A rough construction of those closures and the main properties of the resulting systems are described. Especially, based on the underlying kinetic equation, the main properties desired for such moment systems are the realizability, i.e. the positivity of an underlying kinetic solution, global strong hyperbolicity and entropy dissipation.
Permutation entropy-based characterization of speckle patterns generated by semiconductor laser light

Published: December 2023

Semiconductor lasers with optical feedback are stochastic nonlinear systems that can display complex dynamics and abrupt changes when their operation conditions change. Even very small changes can lead to large variations in the spatial and spectral properties of the laser emission. This makes a semiconductor laser with feedback an ideal system for conducting controlled experiments to test data analysis tools to detect and characterize transitions. Here, we identify feedback-induced transitions by analyzing speckle patterns that are generated after the laser light propagates in an optical fiber. Speckle patterns result from the interference of multiple modes, and their statistical properties are understood, but a direct mathematical model does not exist. Here we show the versatility of the correlation length and the permutation entropy as measures for characterizing speckle patterns. Combining entropy and correlation analysis with speckle contrast analysis, we uncover changes that occur when the laser current increases from below to well above the threshold, which unveils the effects of optical feedback on the coherence of the laser emission.
