Sky-bridges between adjacent buildings can enhance lateral stiffness and limit the impact of lateral forces. This study analysed the structural capabilities and dynamic performances of sky-bridge-coupled buildings under various sets of ground motions. Finite Element (FE) analyses were carried out with the link being iteratively repositioned along the full height of the structures. Incremental dynamic analysis (IDA) and probabilistic damage distribution were also applied. The results indicated that the establishment of sky-bridges caused a slight change in the natural frequency and mode shapes. The sky-bridge system was shown to be efficient in controlling displacement and Inter-Storey Drift Ratio (%ISDR) and reducing the probability of damage in the higher floors. The most efficient location of the sky-bridge, for improving its rigidity, was found to be at 88% of the building height. Finally, the effects of two types of materials (steel and concrete) and end conditions (hinged and fixed) were studied. The outcomes showed that coupled buildings with a sky-bridge made of steel with hinged connection could withstand ground motions longer than those made of concrete with fixed connection.

A Novel Neural Network Ternary Arithmetic Logic Unit
Ali Haidar,M. Jad Hamdan,M. Backer Rashid,Hassan Hamieh,Ahmad Issa,Abdallah Kassem 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
in this paper we introduce a new set of ternary neural networks to realize a novel Ternary Arithmetic Logic Unit (TALU). All the neurons take advantage of the Logic Oriented neural network mathematical tools and parallelism concepts allowing fast and simple systematic analysis. The simulation results, done using MATLAB Simulink, demonstrate the feasibility, functionality and the correctness of the neural networks designed.

Isolated oculomotor nerve palsy secondary to non-aneurysmal subarachnoid hemorrhage
Mehta Shyle,Bathini Abhijith,Dubey Anwesha,Barpujari Awinita,Kassem Ahmad,Sulaiman Mohanad,Binning Mandy 대한뇌혈관외과학회 2022 Journal of Cerebrovascular and Endovascular Neuros Vol.24 No.3
We present a case series of two patients who developed unilateral cranial nerve III (CNIII) palsy following non-aneurysmal SAH (NASAH). Subarachnoid hemorrhage (SAH) can present with various signs and symptoms. Early diagnosis is paramount to determine treatment course. Thus, clinicians must be aware of the variable clinical presentations of this condition. Two patients were admitted to a single institution for SAH. Patient 1, 52-year-old male, presented with headache, left eye ptosis, and painless diplopia. A non-contrast head computed tomography (CT) demonstrated a SAH within the left sylvian fissure and blood surrounding the mesencephalon and falx. Patient 2, 70-year-old male, presented with mild headache, acute onset of blurry vision, and right eye ptosis. A non-contrast head CT demonstrated a diffuse SAH predominantly in the Sylvian and suprasellar cisterns. Patients were admitted to the neuro intensive care unit and underwent diagnostic angiograms to identify possible aneurysms. Magnetic resonance imaging and angiograms for both patients were negative. Patients were managed with best medical therapy and followed up in the outpatient setting. Unilateral CNIII palsy in the setting of NASAH was identified in both patients. Diagnostic angiograms were negative for aneurysms; therefore, SAH were determined to be spontaneous. We propose that unilateral CNIII palsy is a possible sign of NASAH.
