Temperature-dependent development of Spodoptera exigua (Hübner) were evaluated at eight constant temperaturesof 12, 15, 20, 25, 30, 33, 34 and 36 °C with a variation of 0.5 °C on sugar beet leaves. No development occurredat 12 °C and 36 °C. Total developmental time varied from 120.50 days at 15 °C to 14.50 days at 33 °C. Astemperature increased from15 °C to 33 °C, developmental rate (1/developmental time) of S. exigua increased butdeclined at 34 °C. The lower temperature threshold (Tmin) was estimated to be 12.98 °C and 12.45 °C, and thethermal constant (K) was 294.99 DD and 311.76 DD, using the traditional and Ikemoto–Takai linear models, respectively. The slopes of the Ikemoto–Takai linear model for different immature stages were different, violatingthe assumption of rate isomorphy. Data were fitted to three nonlinear models to predict the developmental rateand estimate the critical temperatures. The Tmin values estimated by Lactin-2 (12.90 °C) and SSI (13.35 °C) werehigher than the value estimated by Briere-2 (8.67 °C). The estimated fastest development temperatures (Tfast) bythe Briere-2, Lactin-2 and SSI models for overall immature stages development of S. exigua were 33.4 °C, 33.9 °Cand 32.4 °C, respectively. The intrinsic optimum temperature (TΦ) estimated from the SSI model was 28.5 °C, inwhich the probability of enzyme being in its native state is maximal. The upper temperature threshold (Tmax)values estimated by these three nonlinear models varied from34.00 °C to 34.69 °C. These findings on thermal requirementscan be used to predict the occurrence, number of generations and population dynamics of S. exigua.

In this paper, four apodization functions are proposed for silicon-on-insulator (SOI) strip waveguides with sidewall-corrugated gratings. The effects of apodization functions on the full width at half maximum (FWHM), the side-lobe level, and the reflectivity of the reflection spectrum are studied using the coupled-mode theory (CMT) and the transfer-matrix method (TMM). The results show that applying proposed apodization functions creates very good filtering characteristics. Among investigated apodized waveguides, the apodization functions of Polynomial and z-power have the best performance in reducing side-lobes, where the side-lobe oscillations are entirely removed. Four functions are also used for precise adjustment of the bandwidth. Simulation results show that the minimum and maximum values of the FWHM are 0.74 nm and 8.48 nm respectively. In some investigated functions, changing the apodization parameters decreases the reflectivity which is compensated by increasing the grating length.

Acute respiratory distress syndrome (ARDS) is commonly found in critically ill patients with coronavirus disease 2019 (COVID-19). As a non-pharmacological treatment of complementary and alternative medicine (CAM), cupping has been clinically used for respiratory symptoms. We sequentially identified a series of patients with COVID-19 with ARDS who were admitted to the intensive care unit (ICU). Warm cupping of the posterior thorax was performed for seven days. We collected longitudinal severity scores on cough, breathlessness, chest tightness, type of oxygen therapy, and oxygen saturation (SpO 2 ). We hereby report the changes in the severity scores in a series of eight patients who received 21 sessions of cupping in addition to conventional treatments. All patients reported improvement in symptom scores that was matched by an increase in SpO 2 by as much as 3.16%. All patients were discharged and did not require the use of a mechanical ventilator. The results suggest that combining cupping with conventional treatment may provide a good prognosis for patients with COVID-19 with ARDS.

Orosanga japonica Melichar (Hemiptera: Ricaniidae) is an invasive polyphagous pest in Iran. The planthopper damaged host plants by sap-sucking and egg laying on new twigs. This study aimed to determine the life table parameters of O. japonica on Rubus ulmifolius Schoot (elm leaf blackberry) and Melia azedarach L. (chinaberry) under field conditions in Rudsar (North of Iran) during 2019–2020. The collected life history data were analyzed based on age-stage, two-sex life table theory. The results showed that the incubation period of O. japonica was too long (≈ 270 days) on both host plants. The nymphs emerged from mid-May 2020. The planthopper had five nymphal stages under field conditions. The nymphal duration was 41.39 ± 0.56 days and 38.13 ± 0.62 days on R. ulmifolius and M. azedarach, respectively. The total preadult survival rates were 53.2% and 51.7% on R. ulmifolius and M. azedarach, respectively. Based on the results, a significant shorter total developmental time was observed on M. azedarach. When adults emerged in late July, they laid eggs after 26.05 days and 26.75 days on R. ulmifolius and M. azedarach, respectively. The fecundity on M. azedarach (131.69 egg/female) was significantly higher than that on R. ulmifolius. However, the life table parameters were all not significantly different on the two host plants. The intrinsic rate of increase (r) were 0.0097 ± 0.0005 day − 1 and 0.0105 ± 0.0006 day − 1 on R. ulmifolius and M. azedarach, respectively. Generally, these findings could be helpful to establish an efficient management strategy for this exotic pest.
