Turkish Journal of Veterinary & Animal Sciences

Estimating goat body weight from morphometric traits is essential for growth monitoring, health management, and welfare. Accurate weight informs nutrition, clinical interventions, and mating decisions. In this study, the MARS and XGBoost algorithms were used to estimate the live weight of Kalahari Red goats based on body measurements. A dataset containing body length (BL), birth type (single, twin, or triplet), withers height (WH), rump height (RH), and heart girth (HG) information for 200 goats was used in the training and testing of the models. The performances of the models were evaluated with the goodness-of-fit criteria. XGBoost showed a performance of …

Hatchability And Nestling Viability In An Extremely Short-Beaked Pigeon Breed, Türker Savaş, Hakan Erdem, Cemi̇l Tölü

Turkish Journal of Veterinary & Animal Sciences

The selection of hobby animals for breeding by enthusiasts is often based on aesthetic considerations, which can have a negative impact on the animals’ biology. Furthermore, “extreme traits” that deviate from ancestral norms, such as short beaks in pigeons, can be detrimental to the animal’s welfare. Beaks perform many essential functions, such as facilitating feed intake and eggshell breaking. The present study investigates possible hatching problems and the nestling viability of short-beak pigeons through a study of the breeding records of Mısıri (short beak), Baska (medium beak), and Turkish Dönek (normal beak) pigeons, as well as data from one breeding …

Human Bone Marrow-Mesenchymal Stem Cells Differentiation Into Brain-Like Endothelial Cells, Yomna Soliman, Güli̇n Baran, Nur Mustafaoğlu

Turkish Journal of Biology

Background/aim: Brain microvascular endothelial cells (BMECs), which constitute the blood–brain barrier (BBB), are essential for maintaining central nervous system homeostasis. Like BMECs, multipotent mesenchymal stem cells (MSCs) originate from the mesodermal lineage. Thus, MSCs may serve as a direct and efficient cellular source for BMEC-like differentiation. Notably, differentiation of human induced pluripotent stem cells (hiPSCs) into BMECs typically involves a 2-step protocol: inducing mesodermal commitment followed by endothelial specification. In contrast, direct differentiation from MSCs could bypass the initial mesodermal induction step, offering a streamlined alternative. This study tested a novel strategy for differentiating MSCs into brain-like endothelial cells (BLECs), …

Structure–Activity Modeling And Hybrid Machine Learning-Based Prediction Of Bioactivity In Pyrazole Derivatives For Drug Discovery Applications, Kader Şahi̇n, Serhat Kiliçarslan, Serdar Durdaği, Emi̇n Saripinar

Turkish Journal of Biology

Background/aim: Pyrazole derivatives are of growing interest due to their diverse pharmacological activities. However, their biological activity is often highly sensitive to subtle structural modifications. Existing quantitative structure–activity relationships (QSAR) approaches frequently fail to capture the conformational flexibility and nonlinear structure–activity relationships (SAR) of such heterocyclic scaffolds, creating a gap in the accurate prediction of their biological profiles. Therefore, there is a strong need for more robust and predictive computational frameworks. This study addresses this gap by integrating four-dimensional (4D)-QSAR descriptors with hybrid machine learning (ML) techniques to improve predictive accuracy and provide a more reliable tool for structure-based drug …

Quenching-Based Electrochemiluminescence Detection Of Chlorpyrifos Using A Portable Sensor Platform, Emre Dokuzparmak

Turkish Journal of Biology

Background/aim: Chlorpyrifos (CPF) is an organophosphate pesticide extensively used in agriculture, posing significant threats to human health due to its neurotoxic effects. Its presence in food products has raised considerable public health concerns, necessitating the development of rapid, sensitive, and reliable detection methods. This study aims to design and validate an electrochemiluminescence (ECL) sensor platform operating via a quenching-based mechanism to enable ultrasensitive detection of CPF in food matrices.

Materials and methods: The sensing strategy exploits the coreactant mechanism between 2-(dibutylamino)ethanol (DBAE) and [Ru(bpy)₃]²+ (tris(2,2′-bipyridyl)ruthenium(II)), wherein CPF suppresses the ECL emission by interfering with the excited-state electron transfer pathway. The …

Symmetric Orthogonalization And Probabilistic Weights In Resource Quantification, Gökhan Torun

Turkish Journal of Physics

Transforming nonorthogonal bases into orthogonal ones often compromises essential properties or physical meaning in quantum systems. Here, we demonstrate that Löwdin symmetric orthogonalization (LSO) outperforms the widely used Gram–Schmidt orthogonalization (GSO) in characterizing and quantifying quantum resources, with particular emphasis on coherence and superposition. We employ LSO both to construct an orthogonal basis from a nonorthogonal one and to obtain a nonorthogonal basis from an orthogonal set, thereby mitigating ambiguity related to the basis choice in defining quantum coherence. Unlike GSO, which depends on the ordering of input states, LSO applies a symmetric transformation that treats all vectors equally and …

Optical Textures Of A Uniform Liquid Crystal Lattice: Monte Carlo Simulations With Newton Colors And Mueller Matrix Analysis, Yakup Emül

Turkish Journal of Physics

The optical textures of a uniform liquid crystal (LC) molecule lattice structure were explored through Monte Carlo (MC) simulations, combined with Mueller matrix (MM) formalism and Newton’s color theory. These simulations utilized a Lebwohl-Lasher (LL) type interacting LC lattice under periodic boundary conditions, generating ensemble-averaged configurations at two temperature regimes (kBT = 0.9 and 1.2), corresponding respectively to nematic and isotropic states. These configurations were then incorporated into the MM framework to evaluate the polarization states of transmitted light. To visually interpret the resulting interference phenomena, we propose a new visualization method based on a modern interpretation of Newton’s color …

Scalar Hybrid Meson B̄Gc, Bi̇rten Barsbay İnaç

Turkish Journal of Physics

The scalar hybrid meson H_bc, containing both heavy b and c quarks, represents an intriguing exotic state in QCD. In this article, we investigate its strong decay properties using three-point QCD sum rules. We focus on the two leading decay channels, H_bc → B⁺ D⁰ and H_bc → B⁰ D⁺, which are expected to dominate the decay dynamics. The B and D mesons produced in these decays each consist of one heavy and one light quark. The strong coupling constants at the corresponding vertices are extracted, and the partial decay widths …

The 1/C Expansion Of General Relativity In A 3+1 Formulation, Revisited, Mahmut Elbi̇stan

Turkish Journal of Physics

We study the 1/c expansion of general relativity within a formulation that is compatible with both the Arnowitt-Deser-Misner and the Kol-Smolkin decompositions. The Einstein-Hilbert action takes a common form for those decompositions as they are dual to each other. We first develop a method to expand this generic form and then push the expansion up to c−3 order within this novel approach. Next, we apply our technique to the Arnowitt-Deser-Misner decomposition and expand it up to c−3 order explicitly. In order to demonstrate the applicability of our method and to highlight the duality at the level of expansion, we also …

Outburst Characteristics Of Transient  Low-Mass X-Ray Binary 4u 1608-52, Can Güngör

Turkish Journal of Physics

We present a detailed analysis of the long-term X-ray light curve of 4U 1608–52, focusing on fast-rising exponential-decay (FRED) outbursts, low-intensity states, and quiescent intervals. By calibrating the onset times of the outbursts, we identify three distinct classes for the FRED-type events: (i) the long-high outbursts, exceeding ~50 d in duration with peak count rates above ~40 cnt s-1; (ii) the short-medium outbursts, with durations of ~20 d and peak count rates of ~30-50 cnt s-1; and (iii) the short-low outbursts, also lasting ~20 d but reaching only ~20-30 cnt s-1 at peak. Furthermore, we examine the relation between preoutburst …

New Measurement And Analysis For The 15N + 11B Elastic Scattering System, Nurlan Amangeldi, İsmai̇l Boztosun, Dauren Soldatkhan, Bakytbek Mauyey, Kanat Makhanov, Raimbek Akhat, Aida Anuar, Gani Yergaliuly

Turkish Journal of Physics

New experimental data on the elastic scattering of the nuclear process 15N+11B at an energy of Elab=26.25 MeV were obtained on the DC-60 cyclotron of the INP RK. Based on a semi-microscopic analysis of the interaction of an accelerated 15N ion with 1p-shell nuclei 11B the effectiveness of the new B3Y-Fetal potential was studied. . The difference between the B3Y-Fetal potential and the traditional Yukawa potentials (M3Y-Reid and M3Y-Paris) is that its density-dependent parameters are determined from the saturation condition of nuclear matter at low energy. Analysis was performed on double folding optical model (DFOM) and so no for other …

Mandibular Extension As A Trigger Of The Proprioceptive Trigeminocardiac Reflex, Massimo Conti, Giovanna Traina, Daniele Tonlorenzi

Turkish Journal of Medical Sciences

The trigeminocardiac reflex (TCR) is a physiological response characterized by a reduction in heart rate and arterial blood pressure following stimulation of any branch of the fifth cranial nerve. This review presents a novel mechanism of TCR induction through proprioceptive activation of the trigeminal nerve via mandibular extension (ME). Accordingly, it is referred to as the “proprioceptive trigeminocardiac reflex” (pTCR). An overview of the existing literature on ME-evoked TCR in humans and animals is presented, with particular emphasis on evidence of cerebral microcirculatory alterations. The magnitude of cardiovascular responses appears to depend on the duration of ME, with repeated applications …
