Ijaz Al-Quran dalam Pandangan Muktazilah
Authors: Idris Siregar  , Shofiyatun Nafisah Lubis  , Alhafiz Alhafiz
Published: January 2025

Ijaz Al-Quran or miracles of the Al-Quran is a concept that emphasizes the superiority and uniqueness of the Al-Quran which cannot be matched by humans. In the view of the Muktazilah, a school of Islamic theology that developed in the 8th to 10th centuries AD, Ijaz Al-Quran is analyzed through a rational and theological approach. Muktazilah emphasized that the miracle of the Al-Quran lies in aspects of its language, rhetoric and scientific content which exceed ordinary human abilities. Muktazilah believes that the superiority of the Al-Quran in the linguistic aspect is clear evidence of human inability to produce something comparable. They also consider the harmonious structure and composition of the Al-Quran, as well as the scientific accuracy found therein, to be strong evidence of divine revelation. In view, the miracles of the Al-Quran also include its ability to influence and change human behavior and beliefs. Even though the Muktazilah used a rational approach in interpreting the ijaz of the Al-Quran, they still acknowledged that the main source of this miracle was Allah. They argue that the use of reason and reasoning in understanding the superiority of the Al-Quran does not reduce the spiritual value and belief in revelation. Thus, the Muktazilah's view of the ijaz of the Al-Quran reflects a balance between rationality and spirituality in their theological understanding.

Prevalence of American Foul Brood (AFB) Disease of Hone Bee Apis melllifera (L.) in the Philippines and its Pathogenicity to Apis cerana Fabricius
Authors: Cervancia C.R. , Fajardo, Jr. A.C. , Sabino N.G. , Jamora R. M. , Consignado K.I. , Flores B.F.C.
Published: January 2025

A total of 135 Apis mellifera apiaries spread in Luzon, Visayas and Mindanao were inspected from 2009 to2011 for the presence of American Foul Brood (AFB) disease. Of these, 46% were infected with AFB and 54% were AFB-free. The infection rates in Luzon, Visayas and Mindanao were 31%, 67% and 85%, respectively.

The 21 catalase-negative bacterial isolates obtained from diseased colonies confirmed the presence of Paenibacillus larvae (White,1906), the causal pathogen of AFB. The bacterium is rod-shaped with slightly rounded ends. The rods vary in length, from about 2.5 to 5 microns (µm) and are about 0.5 µm wide. The spore wall turned reddish purple and clear at the center after staining with Carbol fuchsin.

To test for the possible transfer of P. larvae to indigenous bee species, the isolates were incorporated in the larval diet of Apis cerana. One of the 21 isolates was infective to A. cerana 48 hours after introduction. The infected bee larvae showed cloudy body, inflamed gut, sepsis and high number of P. larvae spores.

The proposed strategies for effective management of AFB include burning of infected colonies showing field signs, shook swarm method for colonies with sub-clinical symptoms, and strict implementation of quarantine laws pertinent to importation and inter-island movement of bees. Since there is indication that AFB can be transmitted to A. cerana, introduction of A. mellifera to pristine areas like Bicol Region, Mindoro and some islands in Palawan should not be allowed.
Multiple Mechanisms of Permethrin Resistance in the Red Flour Beetle, Tribolium castaneum Herbst
Authors: Gibe Alexander Joel G. , Motoyama Naoki
Published: January 2025

Permethrin resistance in the red flour beetle (Tribolium castaneum Herbst) was characterized using permethrin-selected (R-per1) strain. In the absence of selection pressure, permethrin resistance was stable for 8 (ca. 8 months) generations and then showed a partial decrease in degree of resistance. The resistance was in a stable level in the succeeding months suggesting two types of resistance mechanism. The KT,0 values obtained by topical application of permethrin exhibited a 2.0 fold knockdown resistance (kdr) against larvae of R-per1 as compared to the susceptible strain. The shortened knockdown time as a result of pretreatment with the metabolic inhibitors PBO and DEF confirmed the presence of kdr factor in the permethrin resistant strain. The cytochrome P450 content as estimated by the CO-binding difference spectrum was 2.2 times larger in adult and 2.7 times larger in larva of permethrin-resistant strain, indicating the participation of monooxygenase system as part of the mechanism of resistance. The third mechanism is the participation of esterases as exhibited by an increased activity in the presence of a- and 13-naphthyl acetates as substrates, implying a relationship between permethrin resistance and degradation by esterases. The implication of such findings was discussed in relation to the current use of grain protectants in managing resistant stored grain insect pests.
Mass-rearing of Broad Mite, Polyphagotarsonemus latus (Banks) (Tarsonemidae,Acari), on Alugbati, Basella rubra L. (Basellaceae), with Notes on Its feeding Damage, Development and Population Growth
Authors: Navasero Marcela M. , Navasero Mario V.
Published: January 2025

Alugbati, Basella rubra L., and several reported host plants of the broad mite were evaluated initially for use as feed in the laboratory. Only alugbati supported active growth of the broad mites while seedlings of castor (Ricinus communis L.), eggplant [Solanum mefongena (L.) (Walp.)], pepper (Capsicum annuum L.) and stringbeans (Vigna unguiculata L.) became etiolated inside the laboratory and did not sustain active growth and development of the pest. The leaves of alugbati shoot terminals are softer, more succulent and would last longer under laboratory conditions because roots develop under water, keeping them fresh longer.

A laboratory mass-rearing technique developed for Polyphagotarsonemus latus (Banks) on alugbati is presented. The technique makes use of alugbati shoots for oviposition and feeding, glass containers for holding the alugbati, and tap water to keep the host materials fresh. A total of 1573 eggs, larvae, deutonymps and adults of P. latus was produced after a week of rearing on alugbati from an initial total population of 603. Alugbati shoot remains attractive for oviposition and feeding of the broad mites for about 10 days and needs to be replaced for continuous rearing and production of the mites.

Alugbati is now included as additional host plant of P. latus, together with saluyot (Corchorus olitorius L.), cholesterol plant (Gynura nepafensis DC), and castor.

Published: January 2025

Five novel microorganisms capable of pyridine dicarboxylic acids degradation were isolated from a soil. Microorganisms utilizing pyridine-2,3-dicarboxylic acid as a sole carbon source were identified as Rhodococcus sp. 23C1, Mycobacterium frederiksbergense 23ON and Cupriavidus campinensis 23K8. This is the first report describing the representatives of these genus capable of degrading this compound. A pyridine-2,3-dicarboxylic acid dehydrogenase (quinolinate dehydrogenase) activity was detected in Rhodococcus sp. 23C1 and Mycobacterium frederiksbergense 23ON. The enzyme was partially purified from Rhodococcus sp. 23C1. Based on detection of nicotinic acid hydroxylase, 6-hydroxynicotinic acid hydroxylase and 2,5-dihydroxypyridine dioxygenase activities in the cell-free extract, a novel pathway of degradation of pyridine-2,3-dicarboxylic acid proceeding via formation of nicotinic acid was proposed for Cupriavidus campinensis 23K8. A bacterial isolate aerobically degrading pyridine-2,6-dicarboxylic acid was identified as Achromobacter sp. JS18. A novel pathway of pyridine-2,6-dicarboxylic acid degradation with 3-hydroxypicolinic acid as an intermediate was proposed for this bacteria. A pyridine-3,5-dicarboxylic acid-degrading bacterial isolate 35KP identified as Xanthobacter sp. was characterized for the first time. A phenazine methosulphate-dependent pyridine-3,5-dicarboxylate dehydrogenase activity was detected in the cell-free extract of Xanthobacter sp. 35KP.
Relation between spectral and spatial properties of gold nanoclusters modified by the morpholine ligand
Authors: Šlėktaitė Akvilė , Kubiliūtė Reda , Sabonis Deividas , Rotomskis Ričardas
Published: January 2025

Recently, gold nanoparticles have received the most attention due to the features and possible applications of their size dependent surface plasmon resonance, which disappears for nanoparticles less than 2 nm in size, that are called gold nanoclusters. Gold nanoclusters, composed of only several to tens of atoms, exhibit molecule-like electronic transitions and size-dependent photoluminescence. This effect offers many possible applications including biological and biochemical sensors and fluorescent bioimaging. Here we report the study of the spectral properties of gold nanoclusters synthesized using a 2-(N-morpholino)ethanesulfonic acid as a capping agent, and their relation to the spatial characteristics of these clusters. We investigated spectral changes of nanoclusters under varying pH value and sample preparation methods and observed the highest photoluminescence intensity at pH 6.3. According to theoretical models we estimated that these particles are composed of 8 atoms, which form a three-dimensional pyramidal structure (C2V). At pH 4.9–5.8 additional plasmonic gold nanoparticles were generated with the calculated size of about 20 nm.

Five test subjects wore the intelligent knee prostheses and performed four walking modes: level walking, uphill walking, downhill walking, and stair descent. The preprocessed gait data were fed into four neural network models: CNN, LSTM, CNN-LSTM, and CNN-bidirectional LSTM. Through hyperparameter tuning, the recognition accuracy of these models was compared. Real-time indicator, gait recognition delay, was also measured. Experimental results showed each model had its strengths and weaknesses. Overall, the CNN-LSTM model achieved the best recognition performance with accuracy rates of: level walking 89%±2.5%, uphill 72.8%±3.2%, downhill 71%±3.2%, and stair descent 96%±2.5%. When switching from level walking to downhill, gait recognition delay was 51.7%±15.6%, and vice versa it was 75.8%±11.5%; when switching from level walking to stair descent, gait recognition delay was 47.1%±17.1%, and vice versa it was 38.6%±10.5%. In summary, the application of the CNN-LSTM model for walking pattern recognition in unilateral intelligent knee prostheses is feasible, with accuracy and real-time performance meeting the control requirements of the prostheses.
A Hybridized CNN-LSTM-MLP-KNN Model for Short-Term Solar Irradiance Forecasting
Authors: El-Shahat Doaa , Tolba Ahmed
Published: January 2025

The accurate prediction of solar irradiance is essential for maximizing renewable energy production. Despite some researchers struggling to achieve sufficient prediction accuracy and model quality, we are working on developing a forecasting model for solar radiation using advanced artificial intelligence techniques. Solar energy offers a sustainable alternative to fossil fuels and has a wide range of applications, making the development of an effective forecasting model crucial. This paper proposes a hybrid model that combines deep learning and machine learning methods, denoted as CNN-LSTM-MLP-KNN. By combining Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), Multilayer Perceptron (MLP) and K-Nearest Neighbors (KNN), we aim to enhance the accuracy and effectiveness of time series forecasting models. The study focuses on extracting spatial and temporal patterns from sun irradiance data using CNN and LSTM and uses MLP to examine intricate connections. The KNN regressor algorithm is employed to make non-parametric forecasts based on the nearest neighbors, resulting in the final forecasting for solar irradiance. Our work relies on the historical Karachi dataset from 2017, 2018, and 2019, sourced from the NSRDB, which provides sun irradiance measurements at a 15-minute time interval using accurate meteorological instrumentation. This dataset covers a 3-year period and comprises 105120 samples with 24 features. Our proposed model provides more accurate predictions compared to the most recent published models, with an R2 score of 0.9874, MSE of 0.0009, RMSE of 0.0311, and MAE of 0.0118.

Una revisión crítica de un experimento mental de Galileo sobre la caída de los cuerpos y el diseño de un experimento alternativo
Authors: Levinas Leonardo
Published: January 2025

In the thought experiment that we study in this article, Galileo attempts to refute the Aristotelian hypothesis that heavier bodies should take less time to fall than lighter ones. After pointing out some inconsistencies in Galileo's approach, we show, through the design of two alternative but equivalent experiments to his, that from his imaginary experiment it is not possible to reach the conclusion that all bodies fall simultaneously into a vacuum. In turn, we design a thought experiment from which it follows that, under the same initial conditions, all bodies, regardless of their weight and composition, must fall with the same acceleration. We show why, to explain the result of this type of experiences, whether real or imaginary, it is necessary to establish the equivalence between inertial and gravitational masses, equivalence derived exclusively from experience and that gave rise to the so-called Equivalence Principle as used in the General Theory of Relativity.
Haciendo Ciencia Nueva
Authors: Céspedes Lucía
Published: January 2025

In this paper, we seek to study the enunciation end of Argentinian magazine Ciencia Nueva (1970-1974), or, in other words, we intend to approach and characterize the enunciating collective. This is to say, we reconstruct Ciencia Nueva’s conditions of production as a scientific and cultural periodical published in the early ’70s through the lived experiences of those who participated in it. Of particular interest are the trajectories of the women who were part of the publication’s stable staff or sporadic contributors, as well as the connections between a public communication of science magazine with strong political overtones and the wider intellectual field of the moment.
La equivalencia formal en el lenguaje de las neuronas lógicas de McCulloch y Pitts
Authors: Stefanazzi Kondolf Rocío
Published: January 2025

In this article we consider the significance of formal equivalence in the language proposed by Warren McCulloch and Walter Pitts in their original “A logical calculus of the ideas immanent in nervous activity”.  We study the model from the contributions that it has meant in the history of science: as a computational theory of mind; and as a formalism that contributed to the development of automata theory and logical design. This question is framed into the mechanistic explanation account and the philosophy of scientific models, while also attending to how the model embedded a conception of a language as a logical calculus. We consider the relationship between the model and its target system, offering two possible interpretations: logical neurons are the model that represents the mind-brain or it is a new conceptual object that enables the development of artificial automata. We observe how the formal equivalence notion plays a fundamental role: as scientific explanation about mind’s theory, as an isomorphism criterion of mind’s model, and as identity criterion of logic neurons or formal neurons.

Published: January 2025

The aim of writing this article is to publish research results related to the role of household consumption, government spending, investment and net exports in influencing economic growth in Indonesia during the 2010-2023 period on a quarterly basis. Econometric analysis using the Error Correction Model (ECM) method is used to test linear regression between the independent variable and the dependent variable. The quantitative data in this research is in the form of secondary data obtained from statistical reports on the websites of the Central Statistics Agency of the Republic of Indonesia (BPS RI), Ministry of Trade of the Republic of Indonesia, Bank Indonesia, Financial Services Authority of the Republic of Indonesia and several related agencies. The results of this research show that together the independent variables consisting of household consumption, government spending, investment and net exports have an effect on economic growth, both in the long and short term. Over the long term, partially the variables household consumption, investment and net exports are positively and significantly correlated with economic growth. Meanwhile, government spending has a negative but not significant correlation with economic growth. For the short term, partially all independent variables in the form of household consumption, government spending, investment and net exports are positively and significantly correlated with economic growth.

Résumé
Résumé
Cet article est une contribution à la littérature sur la réduction de la pauvreté. Malgré l’existence
d’une vaste littérature empirique dans ce domaine, les études n’ont pas accordé beaucoup
d’attention à l’importance des mécanismes de transmission pour déterminer l’influence des
apports de la soutenabilité de la trajectoire de développement et la qualité institutionnelle sur la
réduction de la pauvreté. L’objectif de ce papier est donc d’analyser empiriquement la relation
entre la qualité institutionnelle et la réduction de la pauvreté via l'épargne véritable (indicateur
de soutenabilité) comme mécanisme de transmission indirect dans la zone UEMOA.
L’estimation basée sur le modèle de régressions générées par les résidus, avec des données de
2007 à 2018 montre que la qualité institutionnelle contribue de manière significative
directement et indirectement à travers son influence sur l’épargne véritable à la réduction de la
pauvreté.

Résumé
Résumé
Les envois de fonds des migrants ont reçu une attention particulière dans les débats d’économie
de développement au cours de la dernière décennie. Cet article analyse les canaux de
transmission des effets macroéconomiques de ces envois de fonds des migrants dans les pays
de l’UEMOA. À cet égard, un modèle de panel vectoriel à correction d'erreur a été appliqué
aux données issues des bases de données de la BCEAO et des Indicateurs du Développement
dans le Monde de la Banque Mondiale, sur la période 1994-2016. Ainsi, les résultats montrent
que les envois de fonds des migrants ont une influence positive directe sur le taux de croissance
économique et indirecte à travers la consommation privée, l'investissement privé, le capital
humain et le crédit à l'économie. Par contre, ces fonds constituent une source de pression à la
hausse sur la progression des prix et le taux de change effectif réel. Ainsi, les politiques
appropriées doivent être élaborées pour tirer profit de l’afflux desdits fonds et en contrôler les
éventuels effets retour négatifs transitant par les prix et le taux de change effectif réel.
