Do Logical Aliens Think? Frege’s Agent-Relative View of Logic’s Constitutive Role for Thinking
Authors: Willert Kristoffer Balslev 
Published: June 2024

Abstract
Must you respect basic logical laws (BLL) – such as the law of non-contradiction – in order to think? Frege wrote that one must “acknowledge” BLL in order not to “abandon judgement altogether”. Some have argued that Frege therefore thought of logic as somehow ‘constitutive’ of thinking. However, some interpreters contend, due to his strong commitment to logic’s normative status, that Frege held the opposite view, namely the non-constitutivist view that (systematic) ‘illogical’ thinking is possible and that one need not accept or follow BLL in order to think as such, although one must do so in order to think correctly. The aim of this paper is to investigate the interpretative landscape regarding Frege’s view on logic’s constitutive role for thinking and suggest, against the non-constitutivist readings, that he indeed was committed to some version of the constitutivity thesis, but that this commitment is not, as some constitutivist interpretations suggest, inconsistent with the idea that logic is normative for thinking. I will, instead, propose to read his view in a soft and agent-relative sense, according to which it is a necessary condition for the possibility of thinking that the agent in question is sensitive to and acknowledges BLL.
Impact of parental body mass index at diagnosis on obesity in survivors of pediatric craniopharyngioma
Authors: Beckhaus Julia , Eveslage Maria , Bison Brigitte , Friedrich Carsten , Müller Hermann L 
Published: June 2024

Objective
It is well known that both genetic background and lifestyle influence the development of ‘general’ obesity. However, the role of parental body mass index (BMI) on the development of obesity in long-term survivors of childhood-onset craniopharyngioma (CP) is not well understood. This study analyzed the correlation of patients’ BMI at diagnosis and last visit and parental BMI at CP diagnosis and further explored potential risk factors for obesity in CP patients.

Design
This is a registry-based retrospective cohort study.

Methods
In total,291 CP patients and their parents recruited in the German KRANIOPHARYNGEOM studies were included. Correlations between patient’s BMI SDS at CP diagnosis and last visit and parental BMI at CP diagnosis were analyzed. The associations between hypothalamic damage, maternal/paternal BMI and CP patients’ obesity at last visit were analyzed by multivariable logistic regression.

Results
At follow-up, 52% of CP patients developed obesity (BMI > 3SDS). Patient’s BMI SDS at last visit was moderately correlated with BMI-SDS at CP diagnosis (r = 0.48, 95% CI: 0.38–0.58, P < 0.001), and also with maternal BMI at diagnosis (r = 0.28, 95% CI: 0.17–0.38, P < 0.001) and paternal BMI at diagnosis (r = 0.3, 95% CI: 0.19–0.41, P < 0.001). However, the contributing role of parental BMI to the pathogenesis of obesity was small compared to the impact of hypothalamic damage.

Conclusion
We conclude that besides hypothalamic damage, parental disposition for obesity is associated with the development of obesity in patients after CP. Our results indicate that also the family situation could have an influence on the development of obesity after CP and might be a therapeutic target.

Significance statement
Survivors of childhood-onset craniopharyngioma are at risk of developing morbid obesity. So far, patients with posterior hypothalamic involvement and lesion were identified as a high risk group. With this study, the influence of parental body mass index on the risk of obesity was investigated. Patient’s body-mass-index at last visit was correlated with maternal and paternal body mass index at diagnosis. With increasing maternal or paternal body mass index, the likelihood of obesity in individuals with CP increased. Nevertheless, the parents’ weight had only a small effect on the development of patients’ obesity compared to hypothalamic damage.

Authors: Faridi Marzie , Izadpanah Siros 
Published: June 2024

Introduction: Effective ways of acquiring a second language in an educational context undergo development in teaching and learning through e-learning, self-regulated learning, and constructivism methods of learning that would be practical and useful for EFL learners.
Purpose: To investigate the impact of self-regulated learning, constructivism, and e-learning on English language learning and the attitudes of learners toward them.
Method: The study employs a quantitative research method involving 360 intermediate and advanced EFL learners and 34 teachers. Data were collected over a six-week period in Zanjan English language institutes using the questionnaires. The one-sample T-test compared the means, while ANOVA assessed significant differences among the variable means of E-learning, self-regulation, and constructivism in the study groups. Post-hoc LSD tests were used to compare the means of groups two by two.
Results: The results showed that the participants displayed positive attitudes toward using e-learning, self-regulation, and constructivism in acquiring a second language. Qualitative data analysis revealed EFL learners' autonomy in learning and the potential influence of teachers in shaping learners' attitudes.
Conclusion: This study highlights the importance of considering learners' attitudes and autonomy in designing effective language learning environments. Understanding the learners' perspectives can aid educators in adopting innovative and learner-centered approaches, leading to enhanced language learning outcomes.
Scrutinizing the Relationship between Vietnamese English Majors’ Intrinsic Motivation and Perceptions Towards Five Components of the 5Ts Framework
Authors: Nguyen Thi Diem-Ha 
Published: June 2024

Background: Intrinsic motivation (IM) is not far from a new research topic in English teaching. However, the relationship between this learning construct and the 5Ts framework, proposed by Renandya (2014) as a teacher-induced motivational agent, has not been explored.
Purpose: This work scrutinised the relationship between IM and perceptions towards five components of the 5Ts framework in an attempt to provide a simple means for effective teaching
Method: 110 English majors responded to a self-questionnaire containing two scales measuring IM and perceptions towards the 5Ts as a motivational agent. Besides descriptive statistics and Cronbach’s alpha, the present study employed other necessary techniques, such as Pearson’s correlation and regression, to analyse the obtained data to draw results which had pedagogical implications.
Results: The research questionnaire reached acceptable reliability, and the students expressed positive levels of IM and perceptions of the 5Ts framework. The results also revealed a positive relationship between these two variables, and students’ perceptions of the 5Ts components predicted their IM.
Conclusion: The findings support the hypothesis that the 5Ts framework enhances motivation. In addition, the teacher might need an added approach to enhance the learning motivation in the students with low levels, parallel with the 5Ts implementation for the entire class.
Pressupostos da luta antirracista na formação social brasileira
Authors: Santana Mauro Simões 
Published: June 2024

Research indicators point to the social drama experienced by the black population in the country today. Facing racism is a commitment from the progressive camp to a fairer society. The work is based on the thesis that confronting racism in Brazil must be guided by an understanding of the specificities of the country's political economy in order for it to be effective. Based on a bibliographical review of authors who use historical materialism as a method of analyzing reality, the work intends to point out that racism is a social relationship engendered by the capitalist mode of production. According to these authors, we conclude that racism must be faced under an anti-capitalist orientation. We also conclude that the current tendency to delink the categories of race and class in the demands of black movements reflects a bourgeois counter-revolutionary ideological attack with the aim of relegating anti-racist action to a reformist horizon.

Grapevine leaves have diverse shapes and sizes which are influenced by many factors including genetics, vine phytosanitary status, environment, leaf and vine age, and node position on the shoot. To determine the relationship between grapevine leaf shape or size and leaf canopy temperature, we examined five seedling populations grown in a vineyard in California, USA. The populations had one parent with compound leaves of the Vitis piasezkii type and a different second parent with non-compound leaves. In previous work, we had measured the shape and size of the leaves collected from these populations using 21 homologous landmarks. Here, we paired these morphological data with canopy temperature measurements made using a handheld infrared thermometer. After recording time of sampling and canopy temperature, we used a linear model between time of sampling and canopy temperature to estimate temperature residuals. Based on these residuals, we determined if the canopy temperature of each vine was cooler or warmer than expected, based on the time of sampling. We established a relationship between leaf size and canopy temperature: vines with larger leaves were cooler than expected. By contrast, leaf shape was not strongly correlated with variation in canopy temperature. Ultimately, these findings indicate that vines with larger leaves may contribute to the reduction of overall canopy temperature; however, further work is needed to determine whether this is due to variation in leaf size, differences in the openness of the canopy or other related traits.
Current-Sensorless Robust Sliding Mode Control for the DC-DC Boost Converter
Authors: Oucheriah Said 
Published: June 2024

Abstract

A current-sensorless PWM-based robust sliding mode controller is proposed for the DC-DC Boost Converter,
a nonminimum phase system that presents major challenges in the design of stabilizing controllers. The development of the controller requires the measurement of the output voltage and the estimation of its derivative. An extended state observer is developed to estimate a lumped uncertainty that comprises the uncertain load and input voltage, the converter parasitics, the component uncertainties and also to estimate the derivative of
the output voltage. A linear sliding surface is used to derive the controller that is simple in its design and yet exhibits excellent features in term of robustness to external disturbances, parameter uncertainties and parasitics and despite the absence of the inductor current feedback. Also, a simple procedure to select the controller gains is developed. The robustness of the controller is validated by computer simulations. Future work will be the
validation of these results experimentally.
Promoting Biotic Resistance in Seed-based Wetland Restoration Under Hydrologic Extremes
Authors: Feldman Elana V , Kettenring Karin M. 
Published: June 2024

Abstract

Understanding the factors that drive biotic resistance is important for designing invasion resistant wetland seed mixes. Two factors that affect biotic resistance and can be altered in a seed mix are native plant seeding density and diversity. Here we evaluated the effects of native plant functional group identity (annual forb, bulrush, grass, perennial forb, or rush) and native seeding density (low or high) on the growth of native wetland species and an invader (Phragmites australis) at two sites in the Great Salt Lake Watershed, USA, over two years. We found that the effects of the seeding treatments on biotic resistance appeared to be largely overwhelmed by water depth due to two extreme weather events (severe drought in year 1 and prolonged flooding in year 2). However, these events provided an opportunity to observe the recovery potential of the different functional groups and identify three species (Bolboschoenus maritimus and Schoenoplectus acutus from the bulrush functional group and Distichlis spicata from the grass functional group) that were able to survive the extreme weather conditions during both growing seasons at one of the field sites. Furthermore, we found that different emergent wetland restoration sites can have different plant community outcomes despite geographic proximity, possibly due to distinct site environmental conditions. These findings underscore the importance of using bet-hedging strategies (e.g., seeding diverse mixes with species with a range of hydrologic tolerances) to overcome wetland restoration challenges under hydrologic extremes, conditions likely to become more common with climate change and ever-increasing upstream water diversions.

Abstract

Brazil's significantly large fleet of ethanol-powered vehicles makes it unique with regard to mobile source emissions. An accurate estimation of emission rates is best obtained from studies reflecting real-world vehicular conditions, such as tunnel investigations. Although laboratory-based estimations are standardized, they may not reflect reality. This study evaluates two methods for estimating emission factors that arise from the circulating fleet of vehicles that travel through the Rebouças Tunnel in Rio de Janeiro. The two monitoring points were located in the L1 gallery of the tunnel. Thirteen sampling campaigns took place between 2017 and 2020. The Pearson correlation method yielded emission rates for total aldehydes of 22.1 ± 6.9 mg km− 1, while the fuel consumption testing method resulted in rates of 17.7 ± 7.8 mg km− 1. Acetaldehyde predominated in both methods, as it is a major constituent of the Brazilian fuel matrix. Benzene emerged as the most abundant BTEX compound, with 3.7 ± 3.2 mg km− 1, when the Pearson method was used, and 2.5 ± 0.3 mg km− 1 with the fuel consumption testing method. Naphthalene, which was mainly collected in the gas phase, showed rates of 1.4 ± 1.0 mg km− 1 (Pearson) and 0.9 ± 0.4 mg km− 1 (fuel consumption). Despite these methodological variations, our findings converge, which suggests that the choice of method should depend on available resources. The Pearson method, which requires a vehicle counting method for traffic flow, obviates the need for CO and CO2 concentration measurements, that are essential for determining fuel consumption.
On-chip DNA Assembly via Dielectrophoresis
Authors: Zhao Xin , Wu Lin-Sheng , Rui Xichuan 
Published: June 2024

Abstract

On-chip gene synthesis has the potential to improve the synthesis throughput and reduce the cost exponentially. While there exist several microarray-based oligo synthesis technologies, on-chip gene assembly has yet to be demonstrated. This work introduces a novel on-chip DNA assembly method via dielectrophoresis (DEP) that can potentially be integrated with microarray-based oligo synthesis on the same chip. Our DEP chip can selectively manipulate oligos and guide their movement without perturbing the surrounding fluid medium, thus aiding in DNA assembly. Helical forked electrode design has been optimized for compatibility with DEP, ensuring efficient control over target oligos. By applying an alternating current signal set at 2 MHz, we successfully achieve the desired directed movement of oligonucleotides. Additionally, chemical treatments combined with photoirradiation enabled the connection of complementary gene sequences and the subsequent release of single-stranded DNA products. Sequencing results validate the effective assembly of DNA fragments, approximately 500 base pairs in length, using our DEP device.

Abstract

The single cycad genus Cycas L. of the family Cycadaceae requires special care as they come under the threatened category. The current study focussed on predicting the current, future and paleoclimatic distribution of potentially suitable habitats of Cycas circinalis and Cycas nathorstii in Kerala state and its second northernmost Kannur district. Ensemble function in “sdm” package used to combine five modeling algorithms, namely Generalized Linear Model (GLM), Generalized Additive Model (GAM), Random Forest (RF), Bioclim, Boosted Regression Tree (BRT), and Maximum Entropy (MaxEnt). Individual model validation used the area under the curve and true skill statistics value. Annual mean precipitation was the most contributed predictor for the current suitability model of both species, followed by mean annual temperature and precipitation of the driest month. C. circinalis exhibited a high frequency of least suitable regions, and C. nathorstii showed higher moderately suitable areas in Kerala and suitable regions in the Kannur district. The paleoclimatic suitability of both species in Kerala and Kannur district requires further supporting evidence. The distribution model of C. circinalis to future SSP 245 and SSP 585 scenarios showed a slight increase in suitability from 2021–2040 to 2081–2100 for both extents. Similarly, it favours slightly the suitability of C. nathorstii in all four periods. The niche breadth metric resulted in the habitat specificity for both species in Kerala and less specificity of habitats in the Kannur district, along with niche overlap among them. The study will aid in exploring the new populations in the area based on the model and develop conservation efforts.
Modeling the Effects of Equivalence Ratio on Carbon Nanotubes Diameter in Premixed Flame Based on Semi-Empirical Approach

Published: June 2024

Abstract

In the combustion-based synthesis method, morphological control of carbon nanotubes (CNT) to meet specific demands for technological applications remains a challenge. The present study investigates the effect of equivalence ratio on CNT diameter in a premixed flat flame using a computational method validated by experimental investigations. Six cases were examined in the study by varying the equivalence ratio (∅), a combustion parameter that regulates the overall flame temperature, from 1 to 2 at intervals of 0.2. For each of the six cases, a comprehensive validation of the premixed flat flame temperature as predicted by computational fluid dynamics (CFD) is attained within a 10% deviation. A semi-empirical correlation between CNT diameter and flame temperature was established by deploying the computed flame temperature as the dependent variable in the empirical correlation of existing experimental work that the present study was based on. The findings indicate that the average flame temperature and CNT diameter increased by 5% and 20%, respectively, when the equivalence ratio ∅ was reduced from 2 to 1. Furthermore, only within 6 mm downstream of the flame site does the effect ∅ on CNT diameter become noticeable. According to actual microscopy findings, CNTs with greater diameters within 36–46 nm and smaller diameters within 29–41 nm are expected at high-temperature regions (T > 1300 K) and low-temperature regions (T < 1300 K) within the flame, respectively.

Published: June 2024

Abstract

Management of surface water resources is directly associated with determining the correlation between physical, chemical and biological variables and also identifying their natural and anthropogenic origin. The present study was conducted to scrutinize the correlation between the major parameters affecting the water quality of Shafarood River (Gilan Province, Northern Iran) and to monitor the water quality in different areas of the river using canonical correlation analysis and cluster analysis models, respectively. The measured parameters were five physical parameters and four chemical parameters at five stations based on Standard Methods for the Examination of Water and Wastewater 2015 over six years. The results showed that there was a significant correlation between two categories of response variables (physical parameters) and predictor variables (chemical parameters), which were mainly caused by anthropogenic pollution sources (effluents from residential and garden areas). According to the results of cluster analysis, the stations were grouped into two clusters based on the level of pollution, and the cluster grouping confirmed the data of the canonical correlation matrix. The research findings revealed the effectiveness of the obtained linear combinations for the physical parameters, including total suspended solids and turbidity, as well as the chemical parameters, including biochemical oxygen demand and nitrate. To conclude, the efficiency of canonical correlation analysis and cluster analysis methods was confirmed in identifying the determinant variables of water quality and in classifying the water quality monitoring stations in the optimal management of rivers.
A Novel Side Effect of Blutnimab in B Cell Lymphoma Management - A Captivating Case Report
Authors: Alahmari Awadh , Alnasser Ossamh 
Published: June 2024

Abstract

Introduction: Blutinumab is a commonly used immunotherapeutic agent for acute lymphoblastic leukemia (ALL) that targets B cell lymphoma cells. However, limited knowledge exists regarding its potential neurological side effects. We present a case of a 43-year-old female patient with ALL who developed white matter lesions and cognitive impairment during Blutinumab therapy.
Methods: The patient underwent modified BFM inductions followed by post bone marrow aspiration (BMA) inductions and consolidations. Initial brain CT scan showed no abnormalities, but subsequent imaging three months later revealed symmetrical white matter lesions, confirmed by brain MRI. Extensive investigations, including avascular risk factor assessment, inflammatory and infectious screenings, metabolic evaluations, and cerebrospinal fluid (CSF) analysis, yielded unremarkable results.
Results: Given the absence of alternative etiologies and the temporal association between Blutinumab therapy initiation and the development of neurological symptoms and imaging abnormalities, we hypothesize a potential link between Blutinumab and the observed white matter lesions and cognitive impairment. Neurological side effects, including headache and cognitive impairment, have been reported in approximately 10% to 30% of patients receiving Blutinumab. Conclusion: This case emphasizes the need for increased awareness of potential neurological side effects associated with Blutinumab therapy. Further investigation and monitoring are necessary to establish a definitive causal relationship and optimize patient care. Healthcare professionals should be vigilant in recognizing and managing such adverse events to ensure favorable treatment outcomes.
