conclusions in our population of elderly individuals in northern iran, h. pylori infection was not associated with cognitive impairment in this large population. results the study was performed on 1514 individuals with an average age of 69.3 ± 7.4 years. overall, 836 (55.2 %) of the participants were male. furthermore, 68.7% of the participants had normal mmse score and 75.7% were seropositive ...

b a c k ground: several studies have indicated that executive dysfunction is the main neuropsychological feature of parkinson’s disease (pd). the frontal assessment battery (fab) is a short tool for the assessment of executive functions. p u r p o s e : the aim of this study was to determine the relationship between persian version of fab scores and age, education, mini-mental state examination...

A well–known receiver strategy for a linearly modulated signal transmitted over a frequency–selective channel is channel equalization. Recently it was proposed to employ a minimum mean–squared error (MMSE) channel equalizer for the downlink of CDMA. In this paper, we introduce a new receiver concept using MMSE channel equalization as a first stage and MMSE decision–feedback equalization (DFE) u...

This technical note compares performance of the correlations subtraction architecture of the multistage Wiener filter (CSA-MWF) in the Fractional Fourier Transform (FrFT) domain, MMSE-MWF-FrFT, to the minimum mean-square error, MMSE-FrFT, algorithm and to the conventional MMSE-FFT algorithm in severe cochannel interference. Using four equal power binary phase shift keying (BPSK) signals and a s...

In this paper, a novel robust noncoherent receiver for MMSE interference suppression for DS–CDMA is proposed. The receiver consists of an MMSE filter and a decision–feedback differential detector (DF–DD). The performance of the proposed scheme is investigated analytically and by computer simulations. It is shown that the loss compared to coherent MMSE interference suppression is limited and can...

In real propagation environment, channel reuse causes co-channel interference which will degrade MIMO channel performance. A Successive Interference Cancellation (SIC) detection algorithm with 64-QAM technique is used to improve the quality of received signal in a high interference environment. Using Concatenating MMSE with SIC equalization, better cancellation gain can be achieved. In this pap...

Background: Post operative cognitive decline is more commonly seen in elderly aged patients undergoing noncardiac surgery. The Mini Mental Status Examination (MMSE) score is routinely used as a screening test to assess the cognitive status of a patient. We aimed to assess the trend in cognitive decline among middle (4059years) and elderly age (≥60 years) patients undergoing elective major non-c...

The Mini-Mental State Examination (MMSE) is a widely used screening test for cognitive impairment, but is heavily biased by education. Educational level has frequently been ranked using years of schooling, which may not be a good indirect measure of educational level because there is great heterogeneity in standards of schooling among populations and across regions of the same country. S-TOFHLA...

Objective: To determine whether the Mini-Mental State Examination (MMSE) could be used to predict short-term impairments in memory functions during a course of Electroconvulsive Therapy (ECT). Method: Patients with severe depression (n=32) were followed up while they were receiving ECTs, and up to a month after that. They were rated independently and blindly on the MMSE for global cognitive dys...

This paper deals with arrival time estimation of a narrow-band signal disturbed by white gaussian noise. In order to estimate the distance between a transmitting source and a reflecting target an estimator, based on the criterion of minimum mean square error (MMSE), is investigated. The MMSE-estimator is implemented in an experimental ultrasound pulse-echo system, and results of comparative sim...
