The Emphatic Marker in Turkish: Two Readings

This paper aims to show that the anaphor kendi in Turkish has two distinct readings depending on when it’s functioning as an emphatic marker, which hasn’t been noted in the previous literature. I propose that it has two distinct readings based on their surface sentential positions and diagnostics from Ahn (2010). Moreover, I show that the event modifying a variety of the emphatic marker in Turkish differs from the same type of emphatic marker in English by showing that (i) it allows theme/patient referents, and the DP modifying variety (ii) may be able to survive without obligatory stress. In addition, I document further observations and nuances regarding the morphological marking of the two varieties of the emphatic marker in Turkish as preliminary discussion points.

The combined S velocity achieved from tricuspid annulus and pulmonary annulus with tissue Doppler imaging could predict the proximal right coronary artery occlusion in patients with inferior myocardial infarction

Aim: To investigate if combined S velocity (CSV) calculated from tricuspid annulus and pulmonary annulus with tissue Doppler imaging in individuals with acute inferior myocardial infarction were linked to proximal RCA lesions. Methods: The study comprised 48 patient who had been diagnosed with acute inferior myocardial infarction and had culprit lesions in the right coronary artery. The RCA occlusion in Group A was proximal to the right ventricular branch, while the RCA occlusion in Group B was distant to the RV branch. The combined S velocity was tested, as well as other echocardiographic parameters. Results: In terms of metrics indicating right ventricular function, there were substantial disparities between the groups. A favorable association was established in the univariate correlation analysis between CSV and tissue Doppler imaging derived tricuspid annulus systolic velocity (St), pulmonary annulus motion velocity evaluated by TDI (PAMVUT), RV tricuspid annular plane systolic excursion (TAPSE), and fractional area change (FAC). CSV was identified as an independent predictor of proximal RCA occlusion in a multivariate logistic regression test. In the ROC analysis, CSV<18.3 cm/s and PAMVUT<8.6 cm/s indicated proximal RCA occlusion with 83 percent sensitivity and 71 percent specificity (AUC=0.83, p<0.001), and 85 percent sensitivity and 71 percent specificity (AUC=0.81, p<0.001), respectively. Conclusion: CSV measurements were revealed to be an important predictor of proximal RCA occlusions in this investigation

Great imitator — ocular syphilis

We examined a 44-year-old woman without any known systemic disease with a decreased vision of a month duration in her left eye. She had undergone left uneventful cataract surgery with intraocular lens implantation elsewhere 14 years ago. On examination, her Snellen visual acuity was 1.0 (with the correction of –0.50–0.25 × 120) in the right eye and 0.4 (with the correction of +0.75–2.25 × 115) in the left. There was left hypochromic heterochromia. While the right anterior segment was unremarkable, there were small to medium-sized keratic precipitates, 3+ anterior chamber cells, a posterior chamber intraocular lens with an intact posterior capsule, and a few vitreous cells in the left eye. Fundus autofluorescence imaging revealed peripapillary hyperautofluorescence in the left eye, and fluorescein angiography revealed a marked optic nerve head and perivascular leakage at the posterior pole. The findings were not compatible with Fuchs uveitis, so the full infectious panel was worked out. Serologic investigations yielded the presence of syphilis, and the patient was treated successfully with systemic antibiotics. Our case demonstrates the mimicking nature of ocular syphilis and the importance of high clinical suspicion when reaching the correct diagnosis

Parametric design optimisation of proximal humerus plates based on finite element method

Optimal treatment of proximal humerus fractures remains controversial. Locking plates offer theoretical advantages but are associated with complications in the clinic. This study aimed to perform parametric design optimisation of proximal humerus plates to enhance their mechanical performance. A finite element (FE) model was developed that simulated a two-part proximal humerus fracture that had been treated with a Spatial Subchondral Support (S3) plate and subjected to varus bending. The FE model was validated against in vitro biomechanical test results. The predicted load required to apply 5 mm cantilever varus bending was only 0.728% lower. The FE model was then used to conduct a parametric optimisation study to determine the orientations of inferomedial plate screws that would yield minimum fracture gap change (i.e. optimal stability). The feasible design space was automatically identified by imposing clinically relevant constraints, and the creation process of each FE model for the design optimisation was automated. Consequently, 538 FE models were generated, from which the obtained optimal model had 4.686% lower fracture gap change (0.156 mm) than that of the manufacturer’s standard plate. Whereas its screws were oriented towards the inferomedial region and within the range of neck-shaft angle of a healthy subject. The methodology presented in this study promises future applications in patient-specific design optimisation of implants for other regions of the human body

Electric field measurement on AC power lines

Accidental crane collisions with power lines often result in fatalities or injuries from electrocution. The goal of this project was to create an AC Electric Field sensing device that can be mounted to a crane arm to warn the operator of a dangerous proximity of energized wires. The report covers the important background information for the project's scope. The Project Design Analysis Section describes the design of the system modules. The Performance Analysis Section explains how well the final prototype met the design specifications

Settling Time Measurement Techniques Achieving High Precision at High Speeds

Settling time is very important for data acquisition systems because it is the primary factor that defines the data rate for a given error level. Therefore settling time measurement is a crucial test. The goal of the project was to design, test and compare different measurement techniques. Three methods were tested to the accuracies of 0.1% and 0.01%. Also simulations were conducted to explain the parameters that affect the settling behavior. Additionally bench measurements were correlated to simulation results. This report is intended as a guide for settling time measurements

Retinal Imaging in Neurodegenerative Diseases of Brain

Recent research suggests that Tau is the culprit lesion along with neuroinflammation in the etiology of Alzheimer' s Disease ( AD ). Retina is the extention of the brain and is the most easily approachable part of the central nervous system. Detection of the pathological protein accumulations may be possible by using spectral domain optical coherescent tomography ( SD-OCT ) and fundus autofluorescein ( FAF ). There is evidence showing that retinal plaques start accumulating even earlier than the ones in the brain. Most recent Tau protein images in the brain consist of normal or reverse C-shaped paired hellical filaments
