background: chemicals are among risk factors that can affect women's reproductive system. this study is aimed to investigate the association of occupational exposure to a mixture of organic solvents with menstruation disturbances and hormonal changes among female workers. methods : female workers of a pharmaceutical company were divided into three groups of non-exposed, low-exposed and highly-e...

The present paper demonstrates how a natural crack mosaic resembling random tessellation evolves with repeated 'wetting followed by drying' cycles. system here is network in drying colloidal material, for example, layer of mud. A spring model used to simulate consecutive wetting and cycles mud layers until the matures. simulated results compare favourably reported experimental findings. evoluti...

The results of liver function tests and ultrasonographical findings were analysed in 7 dogs that were intravenously injected dimethylnitrosamine (DMNA 2 mg/kg body weight) on 2 consecutive days each week for 10 weeks. Typical clinical signs and similar changes in liver enzyme concentrations that develop in dogs with natural cirrhosis were observed in this canine model. Severe anaemia and a sign...

The current study assessed the acute effects of pacemaker optimization (PMO) on cardiac function using echocardiographic (ECHO) tissue Doppler imaging (TDI) in the post CRT setting. Data were analyzed from 50 consecutive patients clinically referred for PMO. Patients underwent a sequential ECHO/TDIguided PMO study to determine optimal pacemaker settings. In 34 of 50 patients a change in pacemak...

background: the aim of this study was to evaluate the efficacy and safety of a recombinant human follicle stimulating hormone (r-fsh) low-dose step-up regimen for controlled ovarian hyperstimulation in patients undergoing ovulation induction (oi) with intrauterine insemination (iui). materials and methods: the study was conducted in the department of obstetrics and gynecology, far eastern memor...

Echo state networks are a powerful type of reservoir neural network, but the reservoir is essentially unrestricted in its original formulation. Motivated by limitations in neuromorphic hardware, we remove combinations of the four sources of memory—leaking, loops, cycles, and discrete time—to determine how these influence the suitability of the reservoir. We show that loops and cycles can replic...

Acoustic echo arises due to acoustic coupling between the loudspeaker and the microphone of a communication device. Acoustic echo cancellation and suppression techniques are used to reduce the acoustic echo. In this work we propose to first cancel the early echo, which is related to the early part of the echo path, and subsequently suppress the late echo, which is related to the later part of t...

Flies achieve supreme flight maneuverability through a small set of miniscule steering muscles attached to the wing base. The fast flight maneuvers arise from precisely timed activation of the steering muscles and the resulting subtle modulation of the wing stroke. In addition, slower modulation of wing kinematics arises from changes in the activity of indirect flight muscles in the thorax. We ...
