Association Between Microsatellite Loci And Body Weight Over Generations Of Selection For Growth In Local Selected Chicken Lines, Mariam S. Orabi, Essam A. El-Gendy, Ahmed M. El-Kaiaty, Ellham H. Abbas, Marwa M. Ahmed, Mostafa M. Helal

Turkish Journal of Veterinary & Animal Sciences

The genetic improvement of local chicken breeds is essential for sustainability and adaptability. Marker-assisted breeding can increase the response to selection; however, it requires the identification of marker associations with different traits. Therefore, the current study aimed to evaluate the association between microsatellite marker alleles and the body weight of juvenile chicks over three subsequent generations. Ten microsatellites were used to genotype four chicken lines (two selected and two randombred) across three generations. The lines included the normally feathered selected line (CE1), the normally feathered randombred line (CE2) used as a genetic control for CE1, the naked-neck selected line (CE3), …

Karcı Fractional Artificial Neural Networks (Karcıfann): A New Artificial Neural Networks Model Without Learning Rate And Its Problems, Meral Karakurt, Hülya Saygili, Ali̇ Karci

Turkish Journal of Electrical Engineering and Computer Sciences

The learning rate parameter used in classical artificial neural networks (ANNs) designed with stochastic gradient descent causes problems such as failure to learn, getting stuck in local minima, memorization, and long training times (divergence problem). To address these issues, this paper proposes a novel ANN method that uses a fractional derivative instead of Newton’s derivative. This method is referred to as Karcı fractional ANN (KarcıFANN). In classical ANNs, the weight update is done by assigning the same constant value to the learning rate in each iteration or for a set number of iterations. In contrast, in KarcıFANNs, the weight update …

Robust Sliding Mode Control For Precision Anesthesia Delivery: Addressing Interpatient Variability In Depth Of Hypnosis, Talha Sajjad, Adeel Iqbal, Ali Khaqan, Ali Nauman, Bilal Ijaz, Raja Ali Riaz

Turkish Journal of Electrical Engineering and Computer Sciences

Anesthesia induction is a critical aspect of ensuring patients' health and safety during surgical procedures. The manual administration of anesthesia can lead to serious medical issues due to variability among patients, as well as the risks of overdosing or underdosing anesthetic drugs. While various linear control techniques have been implemented to enhance the safety of anesthesia infusion, non-linear control strategies have demonstrated superior results in achieving the desired level of hypnosis for surgical activities, primarily due to the significant parametric variations present in different patients.Given these challenges, there is a pressing need to develop an efficient anesthesia infusion system that …

A Methodology For Nuclei Segmentation In H&E Images Using Efficientnetb7 Guided U-Net And Multiple Data Augmentation Strategies, Furkan Atlan, Emrah Hançer

Turkish Journal of Electrical Engineering and Computer Sciences

Automating nuclei segmentation in Hematoxylin and Eosin (H&E) stained images is crucial for advancing computational pathology. Despite significant research, challenges such as overlapping nuclei, varying scanner resolutions, and diverse nuclear morphologies continue to hinder segmentation accuracy. In this paper, we propose a deep-learning based methodology that integrates multiple data augmentation strategies with a U-Net architecture enhanced by the EfficientNetB7 encoder. To enhance generalization, we train the model using a combined dataset from MoNuSeg2018, CPM-17, and CoNSeP, exposing it to diverse staining techniques and tissue types. We then evaluate its robustness on the unseen CryoNuSeg dataset, which consists of fully annotated …

Distribution Pattern And Abundance Dynamics Of Asian Openbill (Anastomus Oscitans) In Rice Field Throughout Peninsular Malaysia, Badrulhadza Amzah, Rosli Ramli, Noorhidayah Mamat

Turkish Journal of Zoology

The Asian Openbill (Anastomus oscitans) plays a crucial role in rice field ecosystems by preying on invasive apple snails (Pomacea spp.), potentially reducing the reliance on chemical molluscicides. This study investigated the distribution and abundance dynamics of the stork across major rice granaries in Peninsular Malaysia. Surveys were conducted at 111 sampling points within 30 localities across 11 states during five consecutive rice seasons (2022–2024), with bird counts obtained through binoculars and digital photography. Results indicate that storks are highly concentrated on the northern and central west coasts, where rice fields provide abundant foraging opportunities. In the northern regions (Perlis, …

Discrimination Of Sprat Species (Clupeonella Spp.) In The Caspian Sea And The Sea Of Marmara Using Otolith Shape Analysis, Mohammad Reza Shariati, Mohammad Sadegh Alavi-Yeganeh, Mehdi Ghanbarifardi, Gülşah Saç, Müfi̇t Özuluğ, Erdoğan Çi̇çek

Turkish Journal of Zoology

This study evaluates the discriminating power of sagittal otolith shape among three species of the genus Clupeonella endemic to the Caspian Sea (Clupeonella grimmi, Clupeonella caspia, and Clupeonella engrauliformis) and one species from the Sea of Marmara (Clupeonella Cultriventris). Identification of these species is challenging due to their morphological similarities, and the taxonomic validity of C. caspia and C. cultriventris remains ambiguous because of their resemblance. Scanning electron microscope (SEM) images were utilized to examine the morphological characteristics of otoliths. Stereomicroscope images were used to calculate six shape indices: rectangularity, roundness, ellipticity, circularity, aspect ratio, and form factor. The outline …

Protein Composition Of The Foam Nest Of Rhacophorus Reinwardtii (Schlegel, 1840) (Anura: Rhacophoridae), With Notes On Breeding Sites Characteristics And Biomedical Applications, Muhammad Asyraf Rijalullah, Nia Kurniawan, Nia Kurnianingsih

Turkish Journal of Zoology

Rhacophorus reinwardtii is endemic to Java Island and is currently experiencing a population decline. Therefore, the sustainability of its offspring is important to prevent species extinction. Foam nest as a biosurfactant structure plays a crucial role as egg protection through major protein components function. However, studies on the functional proteins of rhacophoridae foam nests are limited. Thus, this study aims to uncover the protein-specific components and functions of the R. reinwardtii foam nest. Additionally, the characteristics of breeding sites, including abiotic factors, were also assessed. Total protein concentration of the R. reinwardtii foam nest was determined to be 747.7 μg/mL …

A Singular Case Of Early-Stage Long-Distance Dispersal Of The Smooth Newt, Lissotriton Vulgaris (Linnaeus, 1758) (Amphibia, Caudata), Simone Costa, Francesco Paolo Faraone, Mario Lo Valvo

Turkish Journal of Zoology

To date, the global introduction of alien amphibians and reptiles has likely been facilitated by the expanding plant nursery trade. Here, we report in detail a singular case of unintentional introduction of Lissotriton vulgaris in Sicily. A newt in the final stages of its larval development was found in a private garden pond in north-western Sicily, where aquatic plants from a nursery in Veneto (northeastern Italy) had been introduced two months earlier. The analysis of the mithochondrial markers ND2 and ND4 revealed a shared haplotype between the Sicilian newt and a sample from Treviso, the province of the putative source. …

Molecular Crosstalk Of Transcription Factors And Hormones In Drought Tolerance Genes In Plants, Cengi̇z Kaya

Turkish Journal of Botany

Water deficit is a critical challenge to global agricultural productivity and food security, which is exacerbated by climate change and increasing water scarcity. To withstand drought stress, plants employ a variety of molecular strategies driven by complex regulatory networks. This review examines the central role of transcription factors (TFs) as master regulators that activate drought responsive genes, which in turn mediate key adaptive processes such as osmoregulation, antioxidative defense, and membrane stability. A distinctive aspect of this review is its focus on the dynamic interplay between TFs and hormonal signaling pathways, including abscisic acid, ethylene, salicylic acid, and jasmonic acid. …
