The mass of 40 Ti has been determined by using the isobaric multiplet mass equation method. The experimental data of the 40Tiβ-decay were used to determine the level of the isospin analogue state of^( 40)Sc. The ground-state mass excess and the QEc value for 40 Ti were determined to be -9060 ± 12 keV and 11 466 ± 13keV, respectively.

he SARS coronavirus (SARS-CoV) has been identified to be the cause of SARS, yet it remains unclear where the SARS coronavirus evolved from. Evidence suggests the SARS-CoV emerged from animal sources and it has been reported that SARS-CoV like virus were found from Himalayan palm civets in a lived animal market in Guangdong China (Guan et al., 2003). In this work, we studied the existing of SARS-CoV like virus in domestic civets in China. Three civet farms, named CS, ES, WF, in hubei and hunan Provinces of China were investigated. Oral swabs, fecal swabs, and serum samples were taken from about 10 civets in each farm. The oral swabs were tested with RT-PCR for viral nucleic acid and with ELISA for viral antigen. Serum samples were tested with ELISA for SARS-CoV specific antibodies. Some of the RT-PCR products were cloned and sequenced. Tissue samples from certain civets were also collected and observed under electron microscope. In situ hybridization using SARS-CoV specific probes were also performed. Combing the primary results of all the tests, it suggests that SARS-CoV like viruses exist in domestic civets and can cause chronic infection in those animals.

Water wave energy exhibits great potential toalleviate the global energy crisis. However, harvesting andutilizing wave energy are challenging due to its irregularity,randomness, and low frequency. Triboelectric nanogenerators(TENGs) have gained significant attention for harvesting waveenergy with high efficiency. This study presents a novelellipsoidal, pendulum-like TENG integrating both liquid-liquid(L-L) and solid-solid (S-S) triboelectricity (LS-TENG). Thisinnovative design enables continuous wave energy harvestingand self-powered marine environment monitoring under variousconditions, including temperature, humidity, and light intensity. The binary immiscible liquids within the LS-TENG’s innersoft balloon create dynamic, and self-adjustable L-L contact interfaces, significantly increasing the L-L contact area andenhancing L-L contact electrification (CE). The unique self-adaptive, soft S-S contact increases the S-S contact areacompared to traditional hard point contact, better adapting to the irregular movements of waves and promoting efficient S-SCE. The LS-TENG achieves highly efficient wave energy harvesting by coupling L-L and S-S CE. Furthermore, the uniquesoft contact design protects the S-S interfaces from mechanical wear and damage during long-term work. The LS-TENG’snovel structure provides an innovative and effective way for water wave energy harvesting.
