Authors: Uluocak Ihsan , Pinar Engin , Bilgili Mehmet 
Published: July 2024

Abstract

Recently, air pollution has become a critical environmental problem in Türkiye as well as in the world. Therefore, governments and scientists are putting a lot of effort into controlling air pollution and reducing its effects on human society. Scientists propose various models and methods for air quality forecasting because accurate estimation of air quality can provide basic decision-making support. This study proposes innovative hybrid models that integrate a Convolutional Neural Network (CNN) with a Long Short-Term Memory (LSTM) neural network and a Gated Recurrent Unit (GRU) to predict one day ahead of NO2 concentration. For this aim, the Time-Series Daily NO2 concentration data obtained between 2015 and 2022 at the Istanbul and Ankara provinces in Türkiye are used. The hybrid CNN-LSTM and CNN-GRU models are compared with various traditional statistical and machine-learning methods such as Autoregressive Moving Average (ARMA), Artificial Neural Network (ANN), CNN, LSTM, GRU, and Adaptive Neuro-Fuzzy Inference System (ANFIS-FCM). The accuracy of the prediction models is assessed using various statistical criteria and visual comparisons. Results show that the proposed hybrid CNN-LSTM and CNN-GRU models in one-day-ahead NO2 concentration predictions yield the best results among all models with R2 accuracy of 0.9547.
WITHDRAWN: Efficient Real-Time Quantile Regression for Streaming Data
Authors: Li Chris Junchi 
Published: July 2024

Abstract

Quantile regression (QR) is a powerful tool for modeling the conditional quantiles of a response variable given a set of covariates, offering a comprehensive portrayal of their relationship without assuming a specific distribution for the error term. This makes QR particularly suitable for analyzing skewed or heterogeneous data, with wide-ranging applications in fields such as economics and finance. However, traditional QR methods are often impractical for stream data, where data blocks arrive sequentially and demand real-time updates. To address this, we propose a Sequential Quantile Regression (SQR) algorithm that significantly enhances computational efficiency by converting the check loss optimization problem into a least squares problem. The SQR algorithm leverages a Bayesian framework for sequential updates, using the posterior distribution from previous data as the prior for new data. This approach allows for rapid, efficient updates suitable for real-time processing of stream data. We extend the SQR algorithm to Composite Quantile Regression (CQR) and provide theoretical analysis demonstrating the unbiasedness, asymptotic normality, and linear convergence of the SQR estimator. Simulation studies and real data analysis show that SQR offers favorable estimation and inferential performance while being significantly faster than existing methods. Our results highlight the potential of SQR for various applications requiring real-time data processing.

ABSTRACT

The discharge of fluoride-containing wastewater poses a severe threat to global water resources, ecosystems, and human health. Urgently needed are economically feasible and environmentally sustainable solutions for worldwide fluoride contamination. This study explores utilizing unmodified and modified red clay soils from China's Loess Plateau as adsorbents for fluoride mitigation. Sulfuric acid-modified red clay soil showed higher fluoride removal than unmodified, NaOH-modified, and thermally modified soils. Fluoride adsorption decreased with rising pH from 2.0 to 10.0 for unmodified (67.67–3.91%) and acid-modified red clay soil (90.44–32.06%). The Langmuir model better described the data (R2 = 0.9821, 0.9901 for unmodified, acid-modified soil), improving maximum adsorption capacity by 252%. Pseudo-second-order kinetics (R2 = 0.9925, 0.9954 for unmodified, acid-modified soil) accurately described the kinetic data. Acid modification improved reaction rates, shortening the breakpoint from 6.694 to 2.318 min1/2. Over time, the process transitioned from intraparticle diffusion to external mass transfer and intraparticle diffusion. FTIR analysis showed that acid modification strengthened ligand exchange and provided ion exchange opportunities. This study advances fluoride adsorption through innovative clay soil utilization, offering economical, viable, and environmentally friendly solutions.
Analysing the variability of non-stationary extreme rainfall events amidst climate change in East Malaysia

Published: July 2024

ABSTRACT
Climate change is intensifying the occurrence of extreme rainfall events, drawing attention to the importance of understanding the return period concept within the realm of extreme weather studies. This study evaluates the stationarity of extreme rainfall series on both monthly and annual series across East Malaysia, employing the Augmented Dickey–Fuller, Phillips Perron, and Kwiatkowski–Phillips–Schmidt–Shin tests. To model these extreme rainfall series, various probability distributions were applied, followed by goodness-of-fit tests to determine their adequacy. The study identified the stationary and non-stationary return values at 25-, 50-, and 100-year return periods. Additionally, maps depicting the spatial distribution for non-stationary increment were generated. The results indicated that extreme monthly rainfall exhibited stationary characteristics, while extreme yearly rainfall displayed non-stationary characteristics. Among the tested probability distributions, the generalised extreme value distribution was found to be superior in representing the characteristics of the extreme rainfall. Furthermore, a significant finding is that the non-stationary rainfall exhibits higher return values than those of stationary rainfall across all return periods. The northeast coast of Sabah highlighted as the most affected area, with notably high return values for extreme rainfall.
Earthy/musty odour bioaccumulation in Plecoglossus altivelis grown in a land-based aquaculture fed by reclaimed secondary effluent in wastewater treatment plant
Authors: Pham Viet-Dung , Ogata Ei , Kato Hiroyuki 
Published: July 2024

ABSTRACT
Reclaimed wastewater (RWW) has been used globally for centuries, though its application in aquaculture is less extensive. Limited study has addressed impacts of RWW-derived volatile odour compounds (VOCs), such as 2,4,6-trichloroanisole (TCA), 2-methylisoborneol (MIB), and geosmin (GSM), on fish quality. This study aims to (1) assess the feasibility of reusing secondary effluent from a municipal wastewater treatment plant (WWTP) for Plecoglossus altivelis aquaculture in a land-based flow-through system and (2) evaluate the sensory effects of selected VOCs on fish quality. Results showed that increased temperature and ammonia levels in summer RWW negatively affected fish growth, while autumn RWW did not. Heavy metals in fish did not cause health issues. TCA, MIB, and GSM concentrations in fish tissues were 4.7–5.7, 0.3–40.5, and 1.1–1.9 mg kg−1, respectively. TCA emerged as the most concerning odorant, with higher relative odour intensity than MIB and GSM in RWW-cultured fish, regardless of seasonal change. This study is the first to report on a self-constructed aquaculture system using RWW at a WWTP, recommending effective VOC and ammonia removal for sustainable RWW use in aquaculture. Additionally, the study highlighted TCA's impact as an anthropogenic indicator in aquatic environments amid increasing WWTP prevalence in developed cities.

Key Points

Frailty, multimorbidity, and polypharmacy overlap and are associated with higher risk of adverse health outcomes in CKD.Empagliflozin was safe, well tolerated, and effectively reduced cardiorenal and hospitalization risk irrespective of these characteristics.Absolute benefits appeared greater in the most frail participants in this post hoc analysis of EMPA-KIDNEY.

Background
Sodium-glucose cotransporter-2 inhibitors are recommended treatment for adults with CKD, but uncertainty exists regarding their use in patients with frailty and/or multimorbidity, among whom polypharmacy is common. We derived a multivariable logistic regression model to predict hospitalization (reflecting frailty) and assessed empagliflozin's risk–benefit profile in a post hoc analysis of the double-blind, placebo-controlled EMPA-KIDNEY trial.

Methods
The EMPA-KIDNEY trial randomized 6609 patients with CKD (eGFR ≥20 to <45 ml/min per 1.73 m2, or ≥45 to <90 ml/min per 1.73 m2 with urinary albumin-to-creatinine ratio ≥200 mg/g) to receive either empagliflozin 10 mg daily or matching placebo and followed them for 2 years (median). Additional characteristics analyzed in subgroups were multimorbidity, polypharmacy, and health-related quality of life at baseline. Cox regression analyses were performed with subgroups defined by approximate thirds of each variable.

Results
The strongest predictors of hospitalization were N-terminal prohormone of brain natriuretic peptide, poor mobility, and diabetes and then eGFR and other comorbidities. Empagliflozin was generally well tolerated independent of predicted risk of hospitalization. In relative terms, allocation to empagliflozin reduced the risk of the primary outcome of kidney disease progression or cardiovascular death by 28% (hazard ratio, 0.72; 95% confidence interval, 0.64 to 0.82) and all-cause hospitalization by 14% (hazard ratio, 0.86; 95% confidence interval, 0.78 to 0.95), with broadly consistent effects across subgroups of predicted risk of hospitalization, multimorbidity, polypharmacy, or health-related quality of life. In absolute terms, the estimated benefits of empagliflozin were greater in those at highest predicted risk of hospitalization (reflecting frailty) and outweighed potential serious harms.

Conclusions
These findings support the use of sodium-glucose cotransporter-2 inhibitors in CKD, irrespective of frailty, multimorbidity, or polypharmacy.

OBJECTIVE
To explore if oral insulin could delay onset of stage 3 type 1 diabetes (T1D) among patients with stage 1/2 who carry HLA DR4-DQ8 and/or have elevated levels of IA-2 autoantibodies (IA-2As).

RESEARCH AND METHODS
Next-generation targeted sequencing technology was used to genotype eight HLA class II genes (DQA1, DQB1, DRB1, DRB3, DRB4, DRB5, DPA1, and DPB1) in 546 participants in the TrialNet oral insulin preventative trial (TN07). Baseline levels of autoantibodies against insulin (IAA), GAD65 (GADA), and IA-2A were determined prior to treatment assignment. Available clinical and demographic covariables from TN07 were used in this post hoc analysis with the Cox regression model to quantify the preventive efficacy of oral insulin.

RESULTS
Oral insulin reduced the frequency of T1D onset among participants with elevated IA-2A levels (HR 0.62; P = 0.012) but had no preventive effect among those with low IA-2A levels (HR 1.03; P = 0.91). High IA-2A levels were positively associated with the HLA DR4-DQ8 haplotype (OR 1.63; P = 6.37 × 10−6) and negatively associated with the HLA DR7–containing DRB1*07:01-DRB4*01:01-DQA1*02:01-DQB1*02:02 extended haplotype (OR 0.49; P = 0.037). Among DR4-DQ8 carriers, oral insulin delayed the progression toward stage 3 T1D onset (HR 0.59; P = 0.027), especially if participants also had high IA-2A level (HR 0.50; P = 0.028).

CONCLUSIONS
These results suggest the presence of a T1D endotype characterized by HLA DR4-DQ8 and/or elevated IA-2A levels; for those patients with stage 1/2 disease with such an endotype, oral insulin delays the clinical T1D onset.
Revisión sistemática de la integración y la relación entre el pensamiento computacional y las matemáticas en los primeros años escolares
Authors: Ocampo Lina Marcela , Corrales Álvarez Milena , Cardona Torres Sergio Augusto 
Published: July 2024

El pensamiento computacional surge como un área de conocimiento debido a que la tecnología y la informática se han vuelto cada vez más importantes en la sociedad actual. Se ha demostrado que el pensamiento computacional puede mejorar a la resolución de problemas, utiliza técnicas de la ciencia de la computación para desarrollar soluciones a problemas complejos, y a menudo implica la aplicación de principios matemáticos, como el álgebra, la geometría y la estadística. Por otro lado, las matemáticas son fundamentales para el pensamiento computacional, ya que proporcionan la base teórica y conceptual para muchas técnicas de las ciencias de la computación. Los conceptos matemáticos, como las funciones, los conjuntos y la teoría de grafos, son esenciales para la comprensión de muchos algoritmos y estructuras de datos. El objetivo de este trabajo fue analizar la manera en que se han integrado las matemáticas y el pensamiento computacional, y cómo se ha medido esa relación al utilizar actividades conectadas y desconectadas en estudiantes de los primeros años de escolaridad. Se revisaron 302 artículos a los cuales se les aplicaron criterios de inclusión y exclusión asociados a las variables de interés del estudio. Al finalizar la revisión se encuentra que en la mayoría de los artículos se integran las matemáticas y el pensamiento computacional tomando como base la relación que guardan entre sí, y se utilizan estrategias en el aula que favorecen ambos campos del conocimiento; en once de los artículos se proponen actividades desde cuatro componentes matemáticos (geométrico, métrico, espacial y numérico) para abordar el pensamiento computacional, siendo el componente geométrico el más utilizado; solo siete artículos incluyen en su población de estudio el grado 0º y sólo dos artículos trabajan con población de países de Centro (Panamá) y Sur América (Uruguay); lo que podría indicar que el pensamiento computacional está en una etapa naciente en nuestro continente, excluyendo a los países de Norte América donde se reportan un mayor número de artículos.

OBITUARY: Arnold Clemens Ap: His West Papuan legacy lives on
Authors: Maclellan Nic 
Published: July 2024

Arnold Clemens Ap was born on 1 July 1946 on Numfor Island in Biak, at the time, part of the Dutch colony of Netherlands New Guinea. After schooling at church missions in Biak, he studied geography at the Teacher Training School of Cenderawasih University in Abepura, Jayapura, between 1967 and 1973. That year, he was appointed as the curator of the university’s museum, known as Loka Budaya, which became a centre for West Papuan cultural revival. His work to collect and perform songs in Papuan languages played a vital role in the development of a West Papuan national identity, transcending colonial boundaries and inter-tribal conflicts. He was murdered by Indonesian special forces in 1984. This year, 26 April 2024, marked the 40th anniversary of the death of this charismatic cultural leader. For West Papuans, in exile and at home, it has been an important time for commemoration.
Les tractations et les paix des historiens : une lecture de sept chroniques catalanes, aragonaises et siciliennes (XIIIe-XIVe siècles)
Authors: Péquignot Stéphane 
Published: July 2024

A partir de siete crónicas escritas en Sicilia y en la Corona de Aragón entre finales del siglo XIII y el segundo tercio del siglo XIV, este artículo examina cómo los cronistas incluyen la labor diplomática, las negociaciones y los actos conducentes a la paz en sus relatos del conflicto que siguió a las Vísperas sicilianas. Los intercambios diplomáticos eran una faceta de un conflicto más amplio, a veces lo amplificaban; su puesta en práctica era una prueba de fuego para unos protagonistas que deseaban la paz pero dudaban al mismo tiempo de la sinceridad de su enemigo. Aunque la paz parecía a menudo imposible, había dos vías principales para salir del ciclo del conflicto: la gracia divina, que proporcionaba una buena paz, y los acuerdos basados en concesiones mutuas y en la misericordia.
Fondé sur sept chroniques composées en Sicile et dans la couronne d'Aragon entre la fin du XIIIe siècle et le deuxième tiers du XIVe siècle, l'article étudie comment les chroniqueurs font place dans leur récit du conflit consécutif aux Vêpres siciliennes au travail diplomatique, aux négociations et aux actes menant vers la paix. Les échanges diplomatiques constituent une facette d'un conflit plus large, ils l'amplifient parfois ; leur réalisation est une épreuve de vérité pour des protagonistes désireux de paix et doutant de la sincérité de l'ennemi. Si la paix paraît souvent impossible, deux voies principales pour sortir du cycle des conflits apparaissent : la grâce divine, dispensatrice d'une bonne paix ; la convention basée sur des concessions mutuelles et la miséricorde.
