Optimization Of Collection Optics For Maximum Fidelity In Entangled Photon Sources, Kadi̇r Durak

Turkish Journal of Physics

In this report,decoherence sources for entangled photons created by spontaneous parametricdown-conversion phenomenon are studied. The phase and spatial distinguishability of photon pairs from orthogonal crystals reduce the maximum achievable entanglement fidelity. Carefully chosen compensation crystals are used to erase the phase and spatial traces of down-conversion origins. Emission angle of photon pairs also leads to optical path difference and results in phase distinguishability. A realistic scenario is numerically modelled, where the photon pairs with nonzero emission angle gather a phase difference. These pairs can still be collected and manipulated for practical use but the collection optics adds upon the phase …

Analysis Of Chaotic And Regular Behavior Of Matinyan-Yang-Mills-Higgshamiltonian System, Engi̇n Kandiran, Avadi̇s Si̇mon Hacinliyan

Turkish Journal of Physics

In this study we analyze the Matinyan-Yang-Mills-Higgs (MYMH) system, based on semiclassical solutions to a Yang-Mills model, using Poincaré surfaces of section and the method of averaging. To investigate the possible chaotic behavior for the system, we simulate the trajectories of the system and calculate the Lyapunov exponents. We observe that the system displays weakly chaotic behavior. We search for the existence of approximately conserved quantities for the system using the method of averaging. In this way, we show the existence of four fixed points where period orbits exist.

Frequency And Voltage Dependence Of Electrical Conductivity, Complex Electricmodulus, And Dielectric Properties Of Al/Alq3 /P-Si Structure, İkram Orak, Abdulkeri̇m Karabulut

Turkish Journal of Physics

In order to enhance the capacitance of the Al/p-Si metal-semiconductor structure, the Alq3 thin film was coated between these two layers using the spin coating technique as the interlayer. The electrical conductivity, real and imaginary parts of electric modulus, dielectric loss and dielectric constant parameters were examined at the room temperature by the help of admittance measurements in the 100 kHz to 1 MHz frequency range. The effect of frequency on the dielectric constant and dielectric loss values is negligible at the negative voltage values, up to about 0.8 V, and these values rapidly ascended after 0.8 V. The function …

Four-Quark Exotic Mesons, Shahin Agaev, Kazem Azizi, Hayri̇ye Sundu Pamuk

Turkish Journal of Physics

We review our investigations devoted to the analysis of the resonances Zc(3900), Zc(4430), Zc(4100), X(4140), X(4274), α1(1420), Y(4660), X(2100), X(2239), and Y(2175) discovered in various processes by Belle, BaBar, BESIII, D0, CDF, CMS, LHCb and COMPASS collaborations. These resonances are considered as serious candidates to four-quark (tetraquark) exotic mesons. We treat all of them as diquark-antidiquark states with relevant spin-parities, find their masses and couplings, as well as explore their dominant strong decay channels. Calculations are performed in the context of the QCD sum rule method. Thus, the spectroscopic parameters of the tetraquarks are evaluated using the two-point sum rules. …

Electrophysical Properties Of Pb 1-Xmnx Se Epitaxial Films Irradiatedby Γ-Quanta, Rahim Madatov, Rakshana Mamishova, Muslim Mamedov, Javanshir Ismayilov, Ulviya Faradjova

Turkish Journal of Physics

Herein, the effect of γ-quanta on electrophysical and photoelectric properties of p-type Pb1-xMnx Se epitaxial films obtained from the molecular cluster on the glass substrate by the method of condensation has been investigated. It has been established that the acceptor-type local levels with the ionization energy of 0.14 eV and 0.175 eV are generated, when p-type Pb1-xMnx Se (x = 0.01) epitaxial films are irradiated by γ-quanta at D >10 kGy doses. The increase in the photoconductivity in the low temperature range 80-180K is due to the discharge of 0.14eV level, but the decrease in the rate of change of …

Evaluation Of A New Secondary Dose Calculation Software For Gamma Knife Radiosurgery, Michael T Prusator, Tianyu Zhao, James A Kavanaugh, Lakshmi Santanam, Joe Dise, S Murty Goddu, Timothy J Mitchell, Jacqueline E Zoberi, Taeho Kim, Sasa Mutic, Nels C Knutson

Open Access Publications

Current available secondary dose calculation software for Gamma Knife radiosurgery falls short in situations where the target is shallow in depth or when the patient is positioned with a gamma angle other than 90°. In this work, we evaluate a new secondary calculation software which utilizes an innovative method to handle nonstandard gamma angles and image thresholding to render the skull for dose calculation. 800 treatment targets previously treated with our GammaKnife Icon system were imported from our treatment planning system (GammaPlan 11.0.3) and a secondary dose calculation was conducted. The agreement between the new calculations and the TPS were …

Open Access Publications

BACKGROUND: Digital health interventions (DHIs) are poised to reduce target symptoms in a scalable, affordable, and empirically supported way. DHIs that involve coaching or clinical support often collect text data from 2 sources: (1) open correspondence between users and the trained practitioners supporting them through a messaging system and (2) text data recorded during the intervention by users, such as diary entries. Natural language processing (NLP) offers methods for analyzing text, augmenting the understanding of intervention effects, and informing therapeutic decision making.

OBJECTIVE: This study aimed to present a technical framework that supports the automated analysis of both types of …

Cannabidiol In The Horse: Pharmacokinetics And Effects Of A Pelleted Supplement On Reactivity And Movement, Anna L. Draeger

Murray State Theses and Dissertations

A multitude of claims exist regarding therapeutic benefits of cannabidiol (CBD) in human and animal medicine. Though supportive evidence of CBD as a nutraceutical option exists, lack of regulation means that product safety, consistency, and efficacy cannot be guaranteed. Trials for specific conditions and species are needed. The objective of this study was to evaluate CBD safety and use effects on reactivity and movement in the horse. Project 1 examined the bioavailability of a single 50 mg dose of an oil and pelleted CBD product. One of 2 Quarter Horse geldings received the oil product. The second received the pelleted …

Full-Range Space-Division Multiplexing Optical Coherence Tomography Angiography, Yongyang Huang, Jason Jerwick, Guoyan Liu, Chao Zhou

Open Access Publications

In this study, we demonstrated a full-range space-division multiplexing optical coherence tomography (FR-SDM-OCT) system. Utilizing the galvanometer-based phase modulation full-range technique, the total imaging range of FR-SDM-OCT can be extended to >20 mm in tissue, with a digitizer sampling rate of 500 MS/s and a laser sweeping rate of 100 kHz. Complex conjugate terms were suppressed in FR-SDM-OCT images with a measured rejection ratio of up to ∼46 dB at ∼1.4 mm depth and ∼30 dB at ∼19.4 mm depth. The feasibility of FR-SDM-OCT was validated by imaging Scotch tapes and human fingernails. Furthermore, we demonstrated the feasibility of FR-SDM-OCT …

A Mobile App Directory Of Occupational Therapists Who Provide Home Modifications: Development And Preliminary Usability Evaluation, An Thi Nguyen, Emily Kling Somerville, Sandra Martina Espín-Tello, Marian Keglovits, Susan Lynn Stark

Open Access Publications

BACKGROUND: Home modifications provided by occupational therapists (OTs) are effective in improving daily activity performance and reducing fall risk among community-dwelling older adults. However, the prevalence of home modification is low. One reason is the lack of a centralized database of OTs who provide home modifications.

OBJECTIVE: This study aimed to develop and test the usability of a mobile app directory of OTs who provide home modifications in the United States.

METHODS: In phase 1, a prototype was developed by identifying OTs who provide home modifications through keyword Web searches. Referral information was confirmed by phone or email. In phase …
