description: Adaptive design optimization (ADO) is a state-of-the-art technique for experimental design (Cavagnaro, Myung, Pitt, & Kujala, 2010). ADO dynamically identifies stimuli that, in expectation, yield the most information about a hypothetical construct of interest (e.g., parameters of a cognitive model). To calculate this expectation, ADO leverages the modeler's existing knowledge, specified in the form of a prior distribution. Informative priors align with the distribution of the focal construct in the participant population. This alignment is assumed by ADO's internal assessment of expected information gain. If the prior is instead misinformative, i.e., does not align with the participant population, ADO's estimates of expected information gain could be inaccurate. In many cases, the true distribution that characterizes the participant population is unknown, and experimenters rely on heuristics in their choice of prior and without an understanding of how this choice affects ADO's behavior.
 Our work introduces a mathematical framework that facilitates investigation of the consequences of the choice of prior distribution on the efficiency of experiments designed using ADO. Through theoretical and empirical results, we show that, in the context of prior misinformation, measures of expected information gain are distinct from the correctness of the corresponding inference. Through a series of simulation experiments, we show that, in the case of parameter estimation, ADO nevertheless outperforms other design methods. Conversely, in the case of model selection, misinformative priors can lead inference to favor the wrong model, and rather than mitigating this pitfall, ADO exacerbates it.

description: The 3D Discrete Fourier Transform (DFT) is a technique used to solve problems in disparate fields. Nowadays, the commonly adopted implementation of the 3D-DFT is derived from the Fast Fourier Transform (FFT) algorithm. However, evidence indicates that the distributed memory 3D-FFT algorithm does not scale well due to its use of all-to-all communication. Here, building on the work of Sedukhin \textit{et al}. [Proceedings of the 30th International Conference on Computers and Their Applications, CATA 2015 pp. 193-200 (01 2015)], we revisit the possibility of improving the scaling of the 3D-DFT by using an alternative approach that uses point-to-point communication, albeit at a higher arithmetic complexity. The new algorithm exploits tensor-matrix multiplications on a volumetrically decomposed domain via three specially adapted variants of Cannon's algorithm. It has here been implemented as a C++ library called S3DFT and tested on the JUWELS Cluster at the Jülich Supercomputing Center. Our implementation of the shared memory tensor-matrix multiplication attained 88\% of the theoretical single node peak performance. One variant of the distributed memory tensor-matrix multiplication shows excellent scaling, while the other two show poorer performance, which can be attributed to their intrinsic communication patterns. A comparison of S3DFT with the Intel MKL and FFTW3 libraries indicates that currently iMKL performs best overall, followed in order by FFTW3 and S3DFT. This picture might change with further improvements of the algorithm and/or when running on clusters that use network connections with higher latency, e.g. on cloud platforms.

description: Chitosan-based magnetic nanobeads (CBN) were facilely synthesised and applied for selective recovery of boron from highly-saline wastewater. The CBN was characterised, and the results showed that the nanobeads are thermally and mechanically stable to withstand deterioration, had a saturation magnetisation of 65.25 emu/g, the surface area of 635 m2/g and nanobeads size of ∼2.6–3.8 nm. An artificial neural network (ANN) model and Box-Behnken design (BBD) were developed and applied to study the relative effect and significance of input variables affecting boron sorption. Under optimised conditions, 89, 78 and 70% boron removal efficiencies were recorded at pH 7.0 in distilled water, highly-saline water and boron-spiked seawater respectively. The combination of intraparticle diffusion model and pseudo-second-order rate equation was applicable to describe the sorption kinetics.

Year: 2025

description: This article explores the effectiveness of integrating artificial intelligence (AI) into the educational process, with a focus on digital pedagogy and individualized learning approaches. AI technologies such as adaptive learning systems, intelligent tutoring systems, and automated feedback tools have shown great promise in enhancing educational outcomes by personalizing learning experiences, improving engagement, and supporting teachers in their instructional roles. The paper examines how AI facilitates the personalization of learning, automates assessment tasks, and promotes inclusivity in education. Despite these benefits, the article also discusses the challenges associated with AI implementation, including data privacy concerns, algorithmic bias, and the risk of overreliance on technology. The conclusion emphasizes that while AI can transform education, its integration must be guided by ethical principles and a human-centered approach.

description: Introduction: Apples are produced commercially in 34 States in the United States. The four main production areas are the Pacific Northwest, the Midwest, the New York-New England area, and the Appalachian area. The Pacific Northwest produces the largest volume and Washington State produces about one-fifth of the total commercial crop. Commercial production of apples in the United States has been increasing in the postwar years, especially since the mid-1950's. Although the recent increases in production have been about in line with population growth, per capita consumption has been lower than in the years just before World War II, and down considerably from the levels of the 1920's. In addition, there has been a trend toward consuming a larger part of the crop in the form of canned apples and applesauce and less in fresh and dried forms. These developments have accentuated the problems of handling the apple crop and finding profitable markets for it. The increased emphasis on research to improve economic efficiency in apple marketing has indicated the need for a review and digest of recent research on the economics of marketing apples. This digest covers three economic phases of marketing: (1) Demand-supply relationships, (2) merchandising and promotion, and (3) marketing costs and margins.

description: Modeling of Li-ion cells is used in battery management systems (BMS) to determine key states such as state-of-charge (SoC), state-of-health (SoH), etc. Accurate models are also useful in developing a cell-level digital-twin that can be used for protection and diagnostics in the BMS. In this paper, a low-complexity model development is proposed based on the equivalent circuit model (ECM) of the Li-ion cells. The proposed approach uses online impedance measurement at discrete frequencies to derive the ECM that matches closely with the results from the electro-impedance spectroscopy (EIS). The proposed method is suitable to be implemented in a microcontroller with low-computational power, typically used in BMS. Practical design guidelines are proposed to ensure fast and accurate model development. Using the proposed method to enhance the functions of a typical automotive BMS is described. Experimental validation is performed using large prismatic cells and small-capacity cylindrical cells. Root-mean-square error (RMSE) of less than 3\% is observed for a wide variation of operating conditions.

Isostructural 1 and 2 have polymeric chain structures further linked into 3-D porous supramolecular frameworks with 1-D open channels through complicated interchain hydrogen bonding interactions. At 77 K and 1 bar, the dehydrated porous materials 1 and 2 show adsorption behaviors with maximum nitrogen uptakes of 14 and 23 mL g−1, respectively. Complexes 3–5 are 2-D coordination polymers but have different topological structures. Metallohelicate 3 has (4,4) nets composed of left- and right-handed metal–organic helices sharing the common metal centers, but metallohelicate 4 possesses (4·82) topology and 5 has 63-topological structure. In 3 and 5, the polymeric layers are further assembled through regular interlayer hydrogen bonding interactions to form 3-D supramolecular frameworks. Additionally, the thermostabilities of 1–5 as well as the magnetism of 3 were also investigated.

description: Climate change refers to a significant and lasting change in the statistical distribution ofweather patterns in terms of change in average weather conditions or in the distribution ofweather around the average conditions over periods ranging from decades to millions ofyears. Global warming, which refers to the rise in the average temperature of Earth’satmosphere and oceans since the late 19th century, is one of the most visible impacts ofclimate change. Since the early 20th century, Earth’s mean surface temperature has increasedby about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.Scientists are more than 90% certain that this warming of the climate system is primarilycaused by increasing concentrations of greenhouse gases produced by human activities suchas the burning of fossil fuels and deforestation.

description: AbstractThe climatic factors are changing very rapidly in Malaysia. Agriculture which dependsheavily on climate is becoming increasingly vulnerable to risk and uncertainty. In order toface and manage the situation, farmers are trying in various ways and government and otherexternal agencies are providing several supports to adapt to these climatic vulnerabilities.However, there is still a gap between farmers’ adaptability and climate change. This studyanalyses paddy farmers’ perception of climatic variations and vulnerabilities and relevantsupports and techniques to adapt to the situation. The data were collected throughquestionnaire survey on 198 paddy producing farmers in the area of Integrated AgriculturalDevelopment Area (IADA), North-West Selangor, Malaysia. This study uses descriptivestatistics, ordinal regression, percentile, and scale analysis. The study finds that most farmersdo not have a clear perception of the climatic changes and vulnerabilities. Farmers’adaptation practices to climatic vulnerability are mostly based on their common senseresponses. It suggests that farmers need necessary training and support from the governmentand international agencies to enable them to effectively adapt to the climatic vulnerability andavert any adverse effect on their socioeconomic sustainability and national food security.Farmers’ expectations of several new supports has no statistically significant influences ontheir current adaptability with climatic changes, but their priority ranking for these expectedsupports will help policymakers to determine future support for climatic change adaptationfor agriculture sustainability and livelihood sustainability under adverse climatic changescenarios, especially for Malaysia

description: Titanium dioxide nanoparticles (TiO2 NPs) are widely used in foods, cosmetics, and medicine. Although the inhalation toxicity of TiO2 NPs has been studied, the potential adverse effects of oral exposure of low-dose TiO2 NPs are largely unclear. Herein, with macrophage cell lines, primary cells, and mouse models, we show that TiO2 NPs prime macrophages into a specific activation state characterized by excessive inflammation and suppressed innate immune function. After a month of dietary exposure in mice or exposure in vitro to TiO2 NPs (10 and 50 nm), the expressions of pro-inflammatory genes in macrophages were increased, and the expressions of anti-inflammatory genes were decreased. In addition, for macrophages exposed to TiO2 NPs in vitro and in vivo, their chemotactic, phagocytic, and bactericidal activities were lower. This imbalance in the immune system could enhance the susceptibility to infections. In mice, after a month of dietary exposure to low doses of TiO2 NPs, an aggravated septic shock occurred in response to lipopolysaccharide challenge, leading to elevated levels of inflammatory cytokines in serum and reduced overall survival. Moreover, TLR4-deficient mice and primary macrophages, or TLR4-independent stimuli, showed less response to TiO2 NPs. These results demonstrate that TiO2 NPs induce an abnormal state of macrophages characterized by excessive inflammation and suppressed innate immune function in a TLR4-dependent manner, which may suggest a potential health risk, particularly for those with additional complications, such as bacterial infections.

In this article, we use a simplified coupled-Dirac-cone electronic structure model to theoretically evaluate the THz and far infrared Kerr and Faraday responses of thin films of MnBi$_2$Te$_4$ with up to $N=10$ septuple layers with the goal of clarifying the relationship between these convenient magneto-optical observables and the TME. We find that for even $N$ the linear Kerr and Faraday responses to an electric field vanish in the low-frequency limit, even though the magnetoelectric response is large and approximately quantized.

description: Abstract   Private (first sector) and public (second sector) sector economics, both individually and jointly, have failed to ensure the wellbeing of human societies on the national and global levels. In response, social enterprise (third sector) economics, which features cooperatives and not-for-profit social enterprises, foundations (awqāf), and similar undertakings, has emerged as a make-up strategy in an attempt to counter the deficiencies of the market-state economic model. However, there is a strongly felt belief that the third sector needs to be broadened and mainstreamed in order to include both not-for-profit and for-profit businesses blended with social justice (via provision of such social welfare programs as corporate social responsibility) so that they can play a major role in poverty alleviation and economic growth. Islamic entrepreneurship, which is basically a community-centric mode of business initiative, is an antidote to the problem of intolerable economic and social dualism, a natural strategy against all forms of capitalist exploitation and attempts to control a nation’s resources. Moreover, it is the natural model for solving economic inequity, wealth concentration, and social divides. Based on its potential and using examples from Bangladesh and Malaysia, we present the Islamic style of entrepreneurship. We contend that this particular style is the most efficient and desirable one for effectively widening and mainstreaming community-centric third sector economics so that it can ensure development with equity and social justice especially in developing countries.

description: Abstract Despite a bourgeoning literature on the existence of a long-run relationship between energy consumption and economic growth, the findings have failed to establish clearly the direction of causation. A growing economy needs more energy, which is exacerbated by growing population. Evidence suggests that financial development can reduce overall energy consumption by achieving energy efficiency. Economic growth and energy consumption in Malaysia have been rising in tandem over the past several years. The three public policy objectives of Malaysia are: economic progress, population growth and financial development. It is of interest to the policymakers to understand the dynamic interrelation among the stated objectives. The paper implements Auto Regressive Distributed Lag (ARDL) approach to cointegration to examine the existence of a long-run relationship among the series: energy consumption, population, aggregate production, and financial development for Malaysia; and tests for Granger causality within the Vector Error Correction Model (VECM). The results suggest that energy consumption is influenced by economic growth and financial development, both in the short and the long-run, but the population-energy relation holds only in the long run. The findings have important policy implications for balancing economic growth vis-à-vis energy consumption for Malaysia, as well as other emerging nations. 
Supplementary Material from Dynamic disorder in simple enzymatic reactions induces stochastic amplification of substrate.

description: A growing amount of evidence over the last two decades points to the fact that many enzymes exhibit fluctuations in their catalytic activity, which are associated with conformational changes on a broad range of timescales. The experimental study of this phenomenon, termed dynamic disorder, has become possible thanks to advances in single-molecule enzymology measurement techniques, through which the catalytic activity of individual enzyme molecules can be tracked in time. The biological role and importance of these fluctuations in a system with a small number of enzymes, such as a living cell, have only recently started being explored. In this work, we examine a simple stochastic reaction system consisting of an inflowing substrate and an enzyme with a randomly fluctuating catalytic reaction rate that converts the substrate into an outflowing product. To describe analytically the effect of rate fluctuations on the average substrate abundance at steady state, we derive an explicit formula that connects the relative speed of enzymatic fluctuations with the mean substrate level. Under fairly general modelling assumptions, we demonstrate that the relative speed of rate fluctuations can have a dramatic effect on the mean substrate, and lead to large positive deviations from predictions based on the assumption of deterministic enzyme activity. Our results also establish an interesting connection between the amplification effect and the mixing properties of the Markov process describing the enzymatic activity fluctuations, which can be used to easily predict the fluctuation speed above which such deviations become negligible. As the techniques of single-molecule enzymology continuously evolve, it may soon be possible to study the stochastic phenomena due to enzymatic activity fluctuations within living cells. Our work can be used to formulate experimentally testable hypotheses regarding the nature and magnitude of these fluctuations, as well as their phenotypic consequences.

description: ABSTRACT  Climate change has mixed impacts on agriculture and the impacts are different in terms of areas, periods and crops. The changing factors of climate have been exerting strong negative impacts on Malaysian agriculture, which is apprehended to result in shortages of water and other resources for long term, worsening soil condition, disease and pest outbreaks on crops and livestock, sea-level rise, and so on. Due to climate change, agricultural productivity and profitability is declining. Despite continuous increases of government subsidy, area of paddy plantation is decreasing and the adaption practices are ineffective. As climate change is universal and its existence is indefinite, the farmers need to adapt to and find ways to mitigate the damages of climatic variation in order to sustain agricultural productivity and attain food security for them.

subject: FOS: Biological sciences

description: Abstract The changing nature of climatic factors has different impacts on agriculture based areas, periods and crops. Farmers are the most vulnerable group who are affected both directly and indirectly through climatic changes. In the study area in Malaysia, climatic changes have adverse impacts on farmers. Due to climatic change, productivity and profitability of paddy cultivation have declined in the Integrated Agricultural Development Area, North-West Selangor. Farmers perceive that paddy cultivation is no longer profitable due to low productivity as a result of climatic changes. They now prefer full-time to part-time engagement in paddy cultivation. Heavy government subsidy and encouragement are not enough; it requires increase in productivity and profitability of paddy cultivation for making it a viable and sustainable sector. All efforts of mitigation and adaptation must be pursued to counter the adverse impacts of climatic changes and increase the productivity of paddy cultivation in the area. It is observed that there is a high degree of income inequality among the paddy farmers in the study area.

description: Pole-skipping is a property of gravitational waves dictated by their behaviour at horizons of black holes. It stems from the inability to unambiguously impose ingoing boundary conditions at the horizon at an infinite discrete set of Fourier modes. The phenomenon has been best understood, when such a description exists, in terms of dual holographic (AdS/CFT) correlation function that take the value of '0/0' at these special points. In this work, we investigate details of pole-skipping purely from the point of view of classical gravity in 4d massive black hole geometries with flat, spherical and hyperbolic horizons, and with an arbitrary cosmological constant. We show that pole-skipping points naturally fall into two categories: the algebraically special points and a set of pole-skipping points that is common to the even and odd channels of perturbations. Our analysis utilises and generalises (to arbitrary maximally symmetric horizon topology and cosmological constant) the 'integrable' structure of the Darboux transformations, which relate the master field equations that describe the evolution of gravitational perturbations in the two channels. Finally, we provide new insights into a number of special cases: spherical black holes, asymptotically Anti-de Sitter black branes and pole-skipping at the cosmological horizon in de Sitter space.

Supplementary Material from Dynamic disorder in simple enzymatic reactions induces stochastic amplification of substrate

description: A growing amount of evidence over the last two decades points to the fact that many enzymes exhibit fluctuations in their catalytic activity, which are associated with conformational changes on a broad range of timescales. The experimental study of this phenomenon, termed dynamic disorder, has become possible thanks to advances in single-molecule enzymology measurement techniques, through which the catalytic activity of individual enzyme molecules can be tracked in time. The biological role and importance of these fluctuations in a system with a small number of enzymes such as a living cell, have only recently started being explored. In this work, we examine a simple stochastic reaction system consisting of an inflowing substrate and an enzyme with a randomly fluctuating catalytic reaction rate that converts the substrate into an outflowing product. To describe analytically the effect of rate fluctuations on the average substrate abundance at steady state, we derive an explicit formula that connects the relative speed of enzymatic fluctuations with the mean substrate level. Under fairly general modelling assumptions, we demonstrate that the relative speed of rate fluctuations can have a dramatic effect on the mean substrate, and lead to large positive deviations from predictions based on the assumption of deterministic enzyme activity. Our results also establish an interesting connection between the amplification effect and the mixing properties of the Markov process describing the enzymatic activity fluctuations, which can be used to easily predict the fluctuation speed above which such deviations become negligible. As the techniques of single-molecule enzymology continuously evolve, it may soon be possible to study the stochastic phenomena due to enzymatic activity fluctuations within living cells. Our work can be used to formulate experimentally testable hypotheses regarding the nature and magnitude of these fluctuations, as well as their phenotypic consequences.

description: Dimethyl diphenyldithiophosphate complexes of Cr(III), [{(ArO)2PS2}3Cr] [Ar = 2,4-(CH3)2C6H3 (1), 2,5-(CH3)2C6H3 (2),3,4-(CH3)2C6H3 (3), and 3,5-(CH3)2C6H3 (4)], have been synthesized and structurally characterized by IR, heteronuclear NMR (1H, 13C, and 31P) spectroscopic and single crystal X-ray analyses. The crystal structure of complex 4 reveals mononuclear units with the Cr(III) centre chelated in bidentate fashion by six S atoms of the three diphenyldithiophosphate ligands to form octahedral geometry. The main core of the system comprised of four membered (CrS2P)3 heteroatomic ring and Cr(III) center. The ligands and complexes were evaluated for their antibacterial potential against six bacterial strains (K. pneumoniae, E.coli, P. aeruginosa, B. subtilis, S. aureus, and S. typhimurium). The metal derivatives of diphenyldithiophosphate ligands were found to be more active against the bacterial strains as compared to the free ligands.

description: This report contains an evaluation of the university-level certificate programme in "Marine Management and Innovation" (SVF-6013) that was developed and ran as part of the FarFish project. The programme was organised by University of Tromsø (UiT – The Arctic University of Norway) and ran from 9-13th March 2020. A total of 22 students from all across the world attended the programme onsite in Tromsø, and many more watched live streaming from the lectures. The lectures were also recorded and have been available at the FarFish website since then. Throughout the week, participants were trained on topics such as international ocean governance, traceability, value and supply chains, food safety and economics. The training consisted of lectures, group work, field trips and final thesis. Among the 29 participants attending the programme, eight took the exam to be able to receive the certificate, and they all passed. The project therefore reached its goal of graduating at least five participants from the programme.
 The exams, essays with self-chosen topics, contribute to the programme's academic outcome, and with the permission from the respective essay authors, FarFish has publish a summary of six essays on the FarFish web page. The hope is that the essays will act as effective tools to make sure the programme has a learning impact beyond the course. Moreover, it is especially rewarding to know that one of the participants has already acknowledged major impact from taking the programme on his professional life. In a letter we received, the participant wrote about some exciting developments in his professional life, partly attributed to his participation in the FarFish programme.
 The fact that the curriculum and the recorded lectures are now available enhances the impact of the programme, as these outputs will remain as tools for capacity building beyond the FarFish project.
 Overall, the course evaluation revealed that most participants felt the programme taught interesting topics. Most were very satisfied with the course's overall content and quality, despite the sudden change of circumstances related to the COVID-19 restrictions. With this feedback in mind, FarFish is satisfied with how the programme turned out and the impacts it is making. The International Fisheries programme at UiT is now under revision and we wish to integrate some of the FarFish course and experience in the new programme in 2022.

description: A series of novel arylpyrazole derivatives containing aminomethanephosphonate and phenylfuran moieties were designed, synthesized and characterized by 1H NMR, 31P NMR and IR spectroscopy and elemental analyses. The single crystal structure of diethyl [5-(4-chlorophenyl)furan-2-yl][3-cyano-1-(2,3,4-trifluorophenyl)-1H-pyrazol-5-ylamino]methanephosphonate (4l) was determined by X-ray diffraction. Preliminary bioassays showed that these phosphonates exhibit satisfactory insecticidal activities against Culexpipiens and Musca domestica at 0.1%. In particular, compound 4l exhibited a most promising KT50 value, which is superior to that of Dextraltetramethrin® and similar to Prallehtrin®. The structure-activity relationship was also preliminarily investigated.

Subjects: Economics

description: AbstractThis paper primarily examines whether Malaysia has had experienced any structural breaks in comparison with its main two trading partners, namely the USA and Japan in1970s, 1980s, 1990s and 2000s. It also discusses the implications of such structural breaks to Malaysia’s economic globalization at the international level. Using some econometric and statistical tools such as the ADF test, transformed lag equation, Chow Breakpoint test, and CUSUM test, the study reveals that only at 1% level of significance income ratio of Japan and Malaysia has had experienced structural breaks in terms of GDP during the periods 1980s, 1990s, and 2000s. In respect of GNI, the study reveals that only at 5% level of significance their income ratio has had experienced structural breaks during these periods. The study further reveals that income ratio of the USA and Malaysia does not have any structural break both in respect of GNI and GDP.

description: In this article we investigate the existence, uniqueness and exponential decay of asymptotically almost periodic solutions of the parabolic-elliptic Keller-Segel system on a real hyperbolic manifold. We prove the existence and uniqueness of such solutions in the linear equation case by using the dispersive and smoothing estimates of the heat semigroup. Then we pass to the well-posedness of semi-linear equation case by using the results of linear equation and fixed point arguments. The exponential decay is proven by using Gronwall's inequality.
