Objective:To make evidence-based decisions based on broad mortality trends for Razavi Khorasan province,***:In order to determine the baseline number of deaths,we used univariate time series analyses for monthly data from the monthly vital statistics reports(From April 2015 to March 2022).For excess mortalities,these baselines were subtracted from reported deaths with a 95%prediction *** compare time and causes,a P-score was ***:From March 2020 to March 2022,there were 61949 registered deaths,and the estimated deaths with a 95%confidence interval(CI)were 43246.16(35718.28,50774.05).So,in 2020-2021 and 2021-2022,the death counts were 35.15%and 51.33%higher than projected.A total of 18666 cardiovascular diseases were reported and a total of 15704.46(12006.95,19401.96)was *** P-score for this duration was 14.49%and 23.23%higher than *** and parasitic diseases plus COVID-19 were 16633 and estimated to be 1044.87(456.77,1632.96).A total of 4420 diseases of the respiratory system were reported,and 4564.94 deaths were predicted(2277.43,6852.43).In the first year of the pandemic,the P-score dropped to-35.28%and in the second year,it jumped sharply to 22.38%.Conclusions:Excess mortality,along with cause-specific mortality,can be helpful for monitoring trends and developing public health policies at the local,national,and international levels.

An interfacial force microscope （IFM） was employed to measure the inter-particle forces between two individual glass beads with diameters varying from 8 to 20 μm. With the feedback function of IFM turned off, attractive forces were obtained. The forces varied in the range of 0.1-0.34 μN, and their validity was confirmed by a theoretical analysis of the van der Waals force between the same glass beads. With the feedback function switched on, no attractive forces between particles were detected by the IFM when the probe approached the sample substrate. This may be attributed to the dramatic change of the attractive forces within a very short separation distance and/or the relatively poor signal-to-noise ratio of the IFM.
