    Sex Prediction Using Geometric Morphometry with Parameters Obtained from the Orbit, Nasal Bone and Pyriforme Aperture
    (Soc Chilena Anatomia, 2025) Oner, Serkan; Secgin, Yusuf; Erkartal, Halil Saban; Toy, Seyma; Oner, Zulal
    Sex-related changes in the morphometry of the orbit and upper face is an important topic in plastic surgery, forensic sciences and basic medical sciences. With this hypothesis, the aim of this study is to estimate sex using geometric morphometry method with parameters obtained from orbits, nasal bone and pyriforme aperture. The study was performed on Computed Tomography images of 326 individuals aged 25-65 years. The images were three-dimensionalized and superimposed. The real magnification images were then converted to TPS format and 19 homologous landmarks were added to the images. Generalized Procrustes Analysis (GPA) was applied to the obtained coordinates and repositioned around the center of gravity. Principal Component Analysis (PCA) was applied to the new data positioned around the center of gravity to reduce the dimensionality. Linear discriminate analysis (LDA) was applied to the dimensionality-reduced images to obtain sex estimation accuracy. The stud found that 77.126 % of the coordinates gathered around the center of gravity could be explained by the first 3 Principal Component (PCs). LDA analysis applied to the new coordinates yielded a 96.01 % sex prediction rate. As a result of the study, a high accuracy rate was obtained in terms of sex prediction using geometric morphometry method with parameters obtained from the orbit, nasal bone and pyriforme aperture.

    (Nobel Ilac, 2025) Heydarlou, Mehdi Meskini; Kaya, Ayse Demet; Atalik, Kevser; Erbaydar, Tugrul
    Objective: Infections caused by multidrug-resistant (MDR) Gram-negative bacteria and resistance to carbapenems constitute a major public health problem worldwide, due to limited treatment options and high mortality rates. In this study, we aimed to determine the resistance profiles of MDR Gram-negative bacilli isolated from clinical samples to carbapenems. Material and Method: Specimens, from which MDR Gram-negative bacteria were isolated, were cultured onto 5% sheep blood and EMB agar, and VITEK 2 automated system (bio M & eacute;rieux, France) was used for identification and antimicrobial susceptibility testing. Data were analyzed using chi-square and Fisher's exact tests. Results: 1072 MDR bacterial strains were isolated from the specimens of 272 patients, with the majority of transtracheal aspirates (64%) sent predominantly from palliative care (49.8%) and intensive care (42%) units. The leading pathogens were Pseudomonas aeruginosa (42,1%), Acinetobacter baumannii (31,2%), and Klebsiella spp (22,5%). The highest resistance rate among carbapenems was detected to meropenem (91,6%), followed by imipenem (44,3%) and ertapenem (25%). While ertapenem resistance was significantly lower in P. aeruginosa strains (p<0,01), meropenem resistance was significantly higher in A. baumannii strains when compared to other antibiotics. Conclusion: Since Gram-negative MDR bacteria continue to spread rapidly, monitoring resistance profiles through active hospital surveillance is crucial to determine the appropriate treatment. The data obtained in this study once again highlight the importance of resistance to carbapenems and is considered to contribute to epidemiological data.

    Proton Reconstruction with the TOTEM Roman Pot Detectors for High-* LHC Data
    (IOP Publishing Ltd, 2025) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Bergauer, T.; Chatterjee, S.; Zich, J.
    The TOTEM Roman pot detectors are used to reconstruct the transverse momentum of scattered protons and to estimate the transverse location of the primary interaction. This paper presents new methods of track reconstruction, measurements of strip-level detection efficiencies, cross-checks of the LHC beam optics, and detector alignment techniques, along with their application in the selection of signal collision events. The track reconstruction is performed by exploiting hit cluster information through a novel method using a common polygonal area in the intercept-slope plane. The technique is applied in the relative alignment of detector layers with mu m precision. A tag-and-probe method is used to extract strip-level detection efficiencies. The alignment of the Roman pot system is performed through time-dependent adjustments, resulting in a position accuracy of 3 mu m in the horizontal and 60 mu m in the vertical directions. The goal is to provide an optimal reconstruction tool for central exclusive physics analyses based on the high-beta* data-taking period at root s = 13 TeV in 2018.

    Laminar Natural Convection of Water-Fe3O4 Magnetic Nanofluid Over an Annular Finned Vertical Cylinder with a Non-Uniform Magnetic Field
    (Elsevier, 2025) Miansari, Mehdi; Gholamnia, Mehdi; Jasim, Dheyaa J.; Hekmatifar, M.; Salahshour, Soheil
    This study investigates the laminar natural convection of water-Fe3O4 nanofluid with a nanoparticle volume fraction of 4 % around an annular finned vertical cylinder under the influence of a non-uniform magnetic field generated by an electric conductor wire. The three-dimensional problem is solved using the finite volume method, and the effects of fin numbers (2, 4, 8, 12), magnetic field intensities (2 x 106, 5 x 106, 7.5 x 106), and Rayleigh numbers (5 x 104-107) on heat transfer and fluid flow characteristics are analyzed. Results demonstrate that the addition of fins enhances cooling efficiency by generating secondary flows and increasing velocity gradients, particularly at higher Rayleigh numbers. In the absence of a magnetic field, increasing the number of fins from 2 to 12 results in a 28 % to 44 % increase in heat flux, while in the presence of a magnetic field, this increase ranges from 44 % to 150 %. Furthermore, increasing the magnetic field intensity from zero to 7.5 x 106 leads to a heat flux improvement of 26 % to 148 % for a simple cylinder, and 21 % to 277 % for a cylinder with four fins. The study also highlights the non-linear interaction between Rayleigh numbers and magnetic field intensity, where heat transfer initially increases with Rayleigh number but decreases under high magnetic fields due to the suppression of convective flows. These findings underscore the critical role of fin configuration and magnetic field intensity in optimizing heat transfer, with the most effective results occurring at specific Rayleigh numbers and magnetic field strengths.

    An Inventory Model with Price-, Time- and Greenness-Sensitive Demand and Trade Credit-Based Economic Communications
    (MDPI, 2025) Hossain, Musaraf; Rahaman, Mostafijur; Alam, Shariful; Pervin, Magfura; Salahshour, Soheil; Mondal, Sankar Prasad
    Background: Price is the most authoritative constituent among the factors shaping consumer demand. Growing consciousness among global communities regarding environmental issues makes greenness one of the key factors controlling demand, along with time, which drives demand in markets. This paper addresses such issues associated with a retail purchase scenario. Methods: Consumer's demand for products is hypothesized to be influenced by pricing, time and the green level of the product in the proposed model. Time-dependent inventory carrying cost and green level-induced purchasing cost are considered. The average cost during the decision cycle is the objective function that is analyzed in trade credit phenomena, involving delayed payment by the manufacturer to the supplier. The Convex optimization technique is used to find an optimal solution for the model. Results: Once a local optimal solution is found, sensitivity analysis is conducted to determine the optimal value of the objective function and decision variables for other impacting parameters. Results reveal that demand-boosting parameters, for instance, discounts on price and green activity, result in additional average costs. Conclusions: Discounts on price and green activity advocate a large supply capacity by boosting demand, creating opportunities for the retailer to earn more revenue.

    Enhancement of Micromixing Efficiency in Non-Newtonian Blood Flow Using Surface Acoustic Waves: A Study Based on the Carreau-Yasuda Model
    (Korean Soc Rheology, 2025) Faradonbeh, Vahid Rabiei; Salahshour, Soheil; Toghraie, Davood
    This paper comprehensively investigates integrating surface acoustic waves (SAWs) within microfluidic channels to enhance micromixing efficiency. Utilizing the blood flow flowing through the Carreau-Yasuda non-Newtonian fluid model, we examine the behavior of blood analog fluids under the influence of high-frequency acoustic waves. The study employs advanced computational fluid dynamics (CFD) techniques and perturbation theory to solve the modified continuity and momentum equations, revealing the complex interactions between acoustic streaming and fluid flow.

Our results demonstrate significant improvements in mixing performance, with a remarkable increase in fluid homogenization and reaction rates, thereby underscoring the transformative potential of hydro-acoustofluidic systems in biomedical and bioanalytical applications. One of the key outcomes of the present research is achieving rapid homogeneous mixing of blood flow within an extremely short mixing Length of approximately 2 mm, which offers numerous advantages for biological applications. In addition, the sensitivity of micromixing to variations in Reynolds number, which was previously significant, has been reduced by applying acoustic waves and intensifying the acoustic wave strength.

    Assessing Congenital Muscular Torticollis Using Myotonometry: A Novel Approach
    (JMNI, 2025) Azim, Derya; Acar, Gonul; Atici, Emine; Duzel, Turku
    Objective: This study aimed to evaluate sternocleidomastoid (SCM) muscle properties in infants with Congenital Muscular Torticollis (CMT) using myotonometry and determine its sensitivity to changes following physiotherapy. Methods: Twentyfive infants (0-12 months) diagnosed with CMT participated in this study from May 2023 to February 2024. They underwent an 8-week physiotherapy program. Muscle tone, elasticity, and stiffness were measured using myotonometry, muscle strength by the Muscle Function Scale (MFS), and neck range of motion by an arthrodial protractor before and after treatment. Results: The mean age was 4 +/- 1.56 months. Significant differences in SCM tone and stiffness between affected and intact sides were observed pre-treatment (p<0.05) but were not significant post-treatment (p>0.05). Intragroup improvements were significant for muscle tone (p=0.005), elasticity (p=0.009), stiffness (p=0.009), strength (p=0.006), and neck range of motion (p=0.021). Muscle tone decreased by 19.65%, muscle stiffness by 24.99%, and muscle elasticity improved by 9.42%. Passive lateral flexion increased by 59.09% and passive rotation by 25.40%. Conclusions: SCM muscle properties differ between sides in individuals with CMT; however, myotonometry effectively detects improvements following physiotherapy, making it a valuable clinical evaluation tool. Nevertheless, the relatively small sample size should be taken into account when interpreting the findings.

    Impact of High-Concentration Office-Type Bleaching Agent on Physical Properties of Different Types of Bulk-Fill Composites
    (BMC, 2025) Kaynar, Zeynep Buket; Donmez, Nazmiye; Kazak, Magrur; Duc, Bugra
    Background: This study investigated the effect of a 45% carbamide peroxide-containing office-type bleaching agent on the microhardness (MH) and surface roughness (SR) of flowable and paste-type bulk-fill composite resins. Methods: This study used two bulk-fill composite resins, 3 M Filtek Bulk-Fill (paste) and Estelite Bulk-Fill Flow (flowable). Twenty disc-shaped specimens were prepared and divided into two groups according to the type of bulk-fill materials. All samples were stored at room temperature for 24 h with artificial saliva. Initial MH and surface SR values were measured. High-concentration office-type (HCOT) bleaching agent was applied to the samples for 30 min, and then the same procedure was repeated after one week. Following completion of bleaching procedures, final MH and surface SR values were evaluated. The MH values were analyzed by ANOVA and Kruskal-Wallis tests was used for SR values with a significance of 0.05. Results: A statistically significant difference was found between the MH values of the groups before and after bleaching (p = .002). SR value of 3 M Filtek Bulk-Fill was found statistically higher than Estelite Bulk-Fill Flow after or before bleaching treatment. Statistically significant difference was found SR value of 3 M Filtek Bulk-Fill when compared to before and after bleaching procedures (p = .024). Conclusions:Bleaching with high-concentration office-type material significantly reduced the MH of both bulk-fill composites. While HCOT was applied, Estelite Bulk-Fill Flow did not cause a significant change in surface SR. In contrast, the SR value of 3 M Filtek Bulk-Fill was statistically higher. Therefore, if bleaching with a high-concentration office-type bleaching material is planned, it is recommended not to use 3 M Filtek Bulk-Fill as a restorative material, or it may be recommended to renew existing composite resin restorations after bleaching treatment.

    Quadratic High Step-Up Interleaved Z-Source DC-DC Converters Based on Asymmetric Gamma Cell
    (IEEE-Inst Electrical Electronics Engineers Inc, 2025) Daneshgar, Sareh; Babaei, Ebrahim; Sharifian, Mohammad Bagher Bannae
    This article proposes a group of interleaved dc-dc converters based on quasi-impedance source cells with quadratic voltage gain. Using the developed asymmetric gamma impedance source cell with an interleaved technique, the proposed structure minimizes the current stress on the mosfets, the fluctuation of the input current, and losses. Apart from the benefits mentioned above, the proposed structure includes a shared ground, fewer components, low voltage stress across the components, and high efficiency. Necessary theoretical studies are carried out on the proposed structures, including voltage gain calculations, element voltage stress, element design, and element loss calculations. Additionally, a thorough analysis compares the proposed structures with other interleaved converters. Finally, a 400-watt laboratory sample of the first proposed design, operating with a 30 V input voltage, is implemented to validate the stated advantages. The prototype implemented at 400 watts has an efficiency of 96.7%.

    Factors Affecting the Formation of Lymphedema Due to Breast Cancer (Is Primary Systemic Treatment an Independent Factor in the Formation of Breast Cancer Related Lymphedema?)
    (Galenos Publ House, 2025) Kumcuoglu, Melek; Gunay, Semra; Gokcek, Berk
    Objective: This study aimed to evaluate the local and systemic risk factors associated with breast cancer-related lymphedema (BCRL), with a focus on whether primary systemic treatment (PST), particularly taxane-based chemotherapy, is an independent risk factor. Material and Methods: A prospective clinical study was conducted on 80 breast cancer patients discussed at our institution's weekly breast cancer council. Patients were grouped based on PST status. Clinical examinations and measurements were performed preoperatively and postoperatively at 1, 6, 12, 18, and 24 months. Only the operated arm was assessed using tape measurements and the truncated cone formula. Arm volumes were calculated, and lymphedema (LE) was diagnosed based on a volume difference (>= 200 mL or >= 2 cm circumference). Results: No statistically significant differences were found between PST and non-PST groups regarding age, body mass index, menopausal status, smoking, or tumor characteristics. LEwas detected in 7 (8.8%) patients, all Stage 1. PST and taxane-based chemotherapy were not significantly associated with LE development. However, seroma presence (p=0.038) and axillary radiotherapy (p=0.043) were significantly associated with LE. Arm volume increase was most significant at 1 and 18 months postoperatively (p=0.055 and p=0.044, respectively). Conclusion: PST, including taxane-based chemotherapy, does not appear to be an independent riskfactor for BCRL.In contrast, postoperative seroma and axillary radiotherapy are significantly associated with LEdevelopment. Early identification and management strategies should target these modifiable factors to reduce the risk of LE.

    Pathophysiology, Diagnosis, and Management of Coronary Artery Aneurysms: A Review
    (IMR Press, 2025) Guvenc, Rengin Cetin; Al Arfaj, Abdullah Ayar; Razouk, Hola; Guvenc, Tolga Sinan
    Coronary artery aneurysms (CAAs) are frequent entities that are encountered in up to 8% of patients undergoing coronary imaging. The most frequent cause of CAAs is atherosclerotic "positive remodeling" of coronary arteries, while congenital, inflammatory, and traumatic etiologies could also be seen. Aneurysms serve as foci for thrombus formation, which may occlude the aneurysmatic segment or embolize distally. Rupture of an aneurysm is a rare yet potentially catastrophic complication of a CAA. Most aneurysms can be managed medically, while percutaneous exclusion of an aneurysm from coronary circulation is appropriate for CAAs that are prone to rupture or thrombosis. Surgical correction remains the ultimate option for patients who are not amenable to percutaneous management or those with a compelling indication for surgery. This review summarizes the available knowledge on the nomenclature, classification, pathophysiology, diagnosis, and management of CAAs, with a particular emphasis on treatment strategies to mitigate the risks associated with CAAs.

    Eco-Municipalities and Municipal Applications for Sustainability
    (IGI Global, 2012) Bostanci, Seda H.
    Climate change effects, losses in natural environment, limited and diminishing energy sources are great threats for the countries in ecological and social aspects. In recent years some districts in Istanbul have been badly affected by disastrous floods. Climate change might have taken part of this problem but the main reason for the case is shanty housing, and poor location of settlements nearby to riversides, and even within riverbeds. All those experiences increase the necessity of the ecological planning for the settlements and of applying the Eco-municipal model for creating healthy environments. While some phenomena provide against the sustainable development of Turkish cities, solutions will be found in projects with ecological background. The eco-municipality models and municipal applications for sustainability are criticized for not yet finding a sustainable development model for Turkish municipalities. In the improvement of the sustainable municipality concept, some common decision had been taken and defined the related standards. LA21, EMAS for municipalities, and ISO standards are the examples coming forward. The methodology is based on literature review of experiences of the eco-projects that have been made in municipalities and SWOT analyses for these projects. In Turkey, the first step has been taken in LA21 processes to adopt the eco-municipal approach in transformation. For the further steps, the need for establishing an integrated model among the different applications has been concluded.

    A Stochastic Neural Network Procedure for the Nonlinear Typhoid Fever Disease System
    (Springer Wien, 2025) Sabir, Zulqurnain; Akkilic, Ayse Nur; Bulut, Hasan; Umar, Muhammad; Salahshour, Soheil; Saba, Iram
    The aim of this work is to provide the numerical results of the typhoid fever disease system by applying an artificial neural network. The nonlinear typhoid fever disease system is considered into susceptible, exposed, infected, and recovered. The typhoid fever disease system is one of the nonlinear models and numerical results of the system are accomplished via stochastic computing scheme. The optimization is performed by using the Levenberg-Marquardt backpropagation (LMQBP) neural network for solving the nonlinear typhoid fever disease system. An explicit Runge-Kutta solver implemented to calculate the dataset, which is used to lessen the mean square error by data separating into testing (10%), training (70%), and validation (20%). The proposed stochastic scheme is implemented by taking sixteen neurons, log-sigmoid transfer function in the hidden layer, with the input and output layer structure for solving the typhoid fever disease system. The exactness of the scheme is validated by applying the assessment of reference and obtained outputs along with negligible values of the absolute error. Furthermore, the statistical presentations using various disciplines are implemented to indorse the approach's consistency. The proposed stochastic scheme is implemented first time to solve the nonlinear typhoid fever disease system.

    Personalized Alginate Encapsulation: The Role of Autologous Blood Additives in Parathyroid Cell Transplantation
    (Wiley, 2025) Acar, Ozge Karabiyik; Bozdag, Gulnihal; Tuncer, Ahmed Alperen; Hacihasanoglu, Ezgi; Aydogan, Lal Era; Nozhatzadeh, Gulcin Delal; Kose, Gamze Torun
    The only therapeutic intervention for hypoparathyroidism is parathyroid transplantation, but graft rejection is a concern. This study sought to mitigate this problem by utilizing the patient's blood, serum, or plasma in the transplant. To accomplish this objective, blood additives derived from Sprague-Dawley rats are incorporated within alginate, and human parathyroid cells are encapsulated. The prepared microbeads are monitored for mechanical properties, followed by xenotransplantation into rats for the evaluation of cell function and immunological response. Biodegradation data showed that the structural integrity of the microbeads containing blood and plasma is superior to serum, while the durability of plasma-including microbeads is only comparable to that of the alginate-only group. Plasma-including microbeads released the highest levels of parathyroid hormone (PTH), both in vitro and in vivo. This behavior could be attributed to the beneficial impact of plasma on cellular function while regulating immune response. Blood incorporation provoked an elevated immune response while concurrently offering minimal support to the encapsulated cells. A notable elevation in CCL2 (MCP-1) chemokine levels is observed in both blood and alginate-only microbead groups, correlating with CD68 expression. These findings demonstrated that autologous plasma addition may regulate the immune system, thereby diminishing the risk of rejection in cell transplantations.

    Observation of Nuclear Modification of Energy-Energy Correlators Inside Jets in Heavy Ion Collisions
    (Elsevier, 2025) Chekhovsky, V.; Hayrapetyan, A.; Makarenko, V.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Dutta, S.
    Energy-energy correlators are constructed by averaging the number of charged particle pairs within jets, weighted by the product of their transverse momenta, as a function of the angular separation of the particles within a pair. They are sensitive to a multitude of perturbative and nonperturbative quantum chromodynamics phenomena in high-energy particle collisions. Using lead-lead data recorded with the CMS detector, energy-energy correlators inside high transverse momentum jets are measured in heavy ion collisions for the first time. The data are obtained at a nucleon-nucleon center-of-mass energy of 5.02TeV and correspond to an integrated luminosity of 1.70 nb(-1). A similar analysis is done for proton-proton collisions at the same center-of-mass energy to establish a reference. The ratio of lead-lead to proton-proton energy-energy correlators reveals significant jet substructure modifications in the quark-gluon plasma. The results are compared to different models that incorporate either color coherence or medium response effects, where the two effects predict similar substructure modifications.

    Search for High-Mass Resonances in a Final State Comprising a Gluon and Two Hadronically Decaying W Bosons in Proton-Proton Collisions at √s=13 TeV
    (Springer, 2025) Hayrapetyan, A.; Tumasyan, A.; Adam, W.; Andrejkovic, J. W.; Benato, L.; Bergauer, T.; Druzhkin, D.
    A search for high-mass resonances decaying into a gluon, g, and two W bosons is presented. A Kaluza-Klein gluon, gKK, decaying in cascade via a scalar radion R, g(KK) -> gR -> gWW, is considered. The final state studied consists of three large-radius jets, two of which contain the products of hadronically decaying W bosons, and the third one the hadronization products of the gluon. The analysis is performed using proton-proton collision data at root s = 13TeV collected by the CMS experiment at the CERN LHC during 2016-2018, corresponding to an integrated luminosity of 138 fb(-1). The masses of the gKK and R candidates are reconstructed as trijet and dijet masses, respectively. These are used for event categorization and signal extraction. No excess of data events above the standard model background expectation is observed. Upper limits are set on the product of the gKK production cross section and its branching fraction via a radion R to gWW. This is the first analysis examining the resonant WW+jet signature and setting limits on the two resonance masses in an extended warped extra-dimensional model.
