Patients and methods: Between June 2016 and April 2018, a total of 2,361 patients (526 males, 1,835 females, mean age: 45.0 +/- 13.3 years, range, 18 to 75 years) who presented with the complaint of neck pain lasting for at least one month were included in this prospective, cross-sectional study. Data including concomitant dizziness, severity, and quality of life (QoL) impact of vertigo (via Numeric Dizziness Scale [NDS]), QoL (via Dizziness Handicap Inventory [DHI]), mobility (via Timed Up-and-Go [TUG] test), balance performance [via Berg Balance Scale [BBS]), and emotional status (via Hospital Anxiety Depression Scale [HADS]) were recorded. Results: Dizziness was evident in 40.1% of the patients. Myofascial pain syndrome (MPS) was the most common etiology for neck pain (58.5%) and accompanied with cervicogenic dizziness in 59.7% of the patients. Female versus male sex (odds ratio [OR]: 1.641, 95% CI: 1.241 to 2.171, p=0.001), housewifery versus other occupations (OR: 1.285, 95% CI: 1.006 to 1.642, p=0.045), and lower versus higher education (OR: 1.649-2.564, p<0.001) significantly predicted the increased risk of dizziness in neck pain patients. Patient with dizziness due to MPS had lower dizziness severity scores (p=0.034) and milder impact of dizziness on QoL (p=0.005), lower DHI scores (p=0.004), shorter time to complete the TUG test (p=0.001) and higher BBS scores (p=0.001). Conclusion: Our findings suggest a significant impact of biopsychosocial factors on the likelihood and severity of dizziness and association of dizziness due to MPS with better clinical status.Publication Metadata only Expert System for Diagnosis of Multiple Neuromuscular Disorders using EMG Signals(IEEE, 2022) Khan, Muhammad Umar; Hanbali, Raneem; Sharma, Siddhant; Iqtidar, Khushbakht; Aziz, Sumair; Farooq, Adil; University of Engineering & Technology Taxila; Bahcesehir University; University System of Ohio; Wright State University Dayton; National University of Sciences & Technology - Pakistan; University of CyprusAge factors and muscular diseases like amyotrophic lateral sclerosis (ALS) and myopathy significantly reduce muscle activity. Early and accurate diagnosis of ALS and myopathy is of great significance for maintaining better life quality. Electromyogram (EMG) signals of the Biceps Brachii muscles are widely used for the diagnosis of ALS and myopathy through a computer-aided automated system. This results in early diagnosis of the diseases which is helpful in symptom management in the patients. In this article, EMG signals were first filtered using Empirical Mode Decomposition (EMD) through reconstruction of the signal using appropriate Intrinsic Mode Functions (IMFs). Preprocessed signals were reconstructed using relative energy-based thresholding of IMFs. Important features of preprocessed EMG signals were extracted using Mel Frequency Cepstral Coefficients (MFCC) and Gammatone Cepstral Coefficient (GTCC). The final feature vector was constructed by a combination of MFCC and GTCC features. These features were used to train and test Cubic Support Vector Machine (C-SVM). C-SVM yielded the best results of 91.1% mean accuracy for distinguishing between Normal, ALS, and Myopathy signals. The proposed method was compared with a range of other state-of-the-art classification methods. The results of this research advocate the effectiveness of the proposed framework for the accurate diagnosis of neuromuscular diseases in clinical environments.Publication Metadata only On the Source Identification Problem for Hyperbolic-Parabolic Equation with Nonlocal Conditions(AMER INST PHYSICS, 2021) Ashyraliyev, Maksat; Ashyralyev, Allaberen; Zvyagin, Viktor; Ashyralyev, A; Ashyralyyev, C; Erdogan, AS; Lukashov, A; Sadybekov, M; Bahcesehir University; Near East University; Peoples Friendship University of Russia; Institute of Mathematics & Mathematical Modeling; Voronezh State UniversityIn the present paper, we establish the well-posedness of an identification problem for determining the unknown space-dependent source term in the hyperbolic-parabolic equation with nonlocal conditions.

Numerical results are given for a simple test problem.Publication Metadata only SCORING: Towards Smart Collaborative cOmputing, caching and netwoRking paradIgm for Next Generation communication infrastructures(IEEE, 2022) Hmitti, Zakaria Ait; Ben Ammar, Hamza; Soyak, Ece Gelal; Kardjadja, Youcef; Malektaji, Sepideh; Ali, Soukaina Ouledsidi; Rayani, Marsa; Saqib, Muhammad; Taghizadeh, Seyedreza; Ajib, Wessam; Elbiaze, Halima; Ercetin, Ozgur; Ghamri-Doudane, Yacine; Glitho, Roch; University of Quebec; University of Quebec Montreal; Sabanci University; Concordia University - Canada; Bahcesehir UniversityThe unprecedented increase of heterogeneous devices connected to the Internet, along with tight requirements of future networks, including 5G and beyond, poses new design challenges to network infrastructures. Collaborative computing, caching and communication paradigm together with artificial intelligence have the potential to enable the Next-Generation Networking Infrastructure (NGNI) that is needed to fulfill the stringent requirements of emerging applications. In this paper, we propose the SCORING project vision for reshaping the current network infrastructure towards an NGNI acting as a truly distributed, collaborative, and pervasive system that enables the execution of application-specific tasks and the storage of the related data contents in the Cloud-Edge-Mist continuum with high QoS/QoE guarantees.Publication Metadata only Numerical solution of the boundary value problems for the parabolic equation with involution(KARAGANDA STATE UNIV, 2023) Ashyralyev, A.; Ashyralyyev, C.; Ahmed, A. M. S.; Bahcesehir University; Peoples Friendship University of Russia; Institute of Mathematics & Mathematical Modeling; National University of UzbekistanIn this work, we study two boundary value problems for involutary parabolic equation with the first and second kind conditions.

Benavides; Demirkan, I.; Tsoukas, M.; Avanaki, K.; Choi, B; Zeng, H; University of Illinois System; University of Illinois Chicago; University of Illinois Chicago Hospital; Bahcesehir University; University of Illinois System; University of Illinois Chicago; University of Illinois Chicago Hospital; University of Illinois System; University of Illinois Chicago; University of Illinois Chicago HospitalThis study aims to make the implementation of the attenuation and backscattering study to be apply for skin tissue. Attenuation and backscatter coefficients were defined in the range 22 to 48 MHz based on the L38 transducer which has a central frequency of 30 MHz and a 60% bandwidth. The attenuation coefficient was computed using local attenuation estimation algorithms (i.e., spectral difference and spectral log difference methods). Using a reference phantom technique, we compensated the recorded backscatter spectra for system-independent measurements. This study shows the experimental and theoretical steps needed to implement a quantitative study of ultrasounds images in the skin.Publication Metadata only Effect of Electron's Drift Velocity in Nonlinear Ion-Acoustic Solitons in a Negative Ion Beam Plasma(SPRINGER INTERNATIONAL PUBLISHING AG, 2024) Kalita, J.; Das, R.; Hosseini, K.; Hincal, E.; Salahshour, S.; Ma, WX; Manukure, S; Gauhati University; Near East University; Okan University; Bahcesehir UniversityIn the present paper, the authors have explored the existence of KdV and mKdV solitons in a collisionless and unmagnetized plasma model involving positive ion and negative ion beams together with thermal electrons. For various selections of Q'(= m(b)/m(i), negative ion beam to positive ion mass ratio) larger and less than one, low amplitude rarefactive and compressive KdV solitons are created in the plasma under the effect of the electron's drift velocity v'(e). In two intervals of drift velocity v'(e) for 0 <= v'(e) <= 26 and 26.5 <= v'(e) <= 28.5 when Q' is less than one, the existence of the mKdV solitons is demonstrated.Publication Metadata only Characterizing Attenuation of Bumper Modifications: A Comparative Study in the E-Band(IEEE, 2024) Neubauer, Michael; Hirschmugl, Michael; Petanjek, David; Kiebach, Helge; Karamzadeh, Saeid; Kolosovs, D; Anstalt fur Verbrennungskraftmaschinen List; Bahcesehir UniversityHaving knowledge about the attenuation of the materials surrounding a radar sensor is of great importance in the automotive sector. Only then can the manufacturer guarantee the desired functionality of the sensor. Due to the fact that a lot of automotive manufacturers also started integrating radar sensors behind rear bumpers for improved visibility to the back of a car, it is vital to know how those bumpers and possible repair scenarios done to them can affect the radar sensor. This paper proposes a way to measure the attenuation in the E-band of not only square slab samples representing various types of paint and repair scenarios on automotive bumpers, but also actual rear bumpers with different types of repair scenarios. The results are then presented and compared relative to each other.
