We investigated precision measurements in a two-level system coupled to a single-photon-added coherent state (SPACS) under postselected weak measurement. We analyzed strategies for improving measurement precision, including parameter estimation and the signal-to-noise ratio (SNR) in postselected wea...

Proanthocyanidins, which are polyphenolic compounds resulting from the condensation of monomeric flavan-3-ols, exhibit antibacterial activity. This study aimed to investigate the impact of proanthocyanidins on the growth and cell membrane of Acetobacter sp., as well as explore their interaction with...

Mode-division multiplexing (MDM) has been considered as a low-cost and high-density means for high-bandwidth on-chip optical communications in a high-performance computer and a data center. However, simultaneously controlling the power of multiple modes in the MDM systems is difficult due to the com...

BackgroundTo examine the effects of thyroid hormone (TH) levels on colon cancer progression, HCT-116 colon cancer cells were inoculated into the axillary region of thymus-deficient male BALB/c nude mice. Mild hypothyroidism and hyperthyroidism were then induced to observe tumor growth patterns under...

Apple necrotic mosaic virus (ApNMV) was identified in crabapple trees with mosaic symptoms from Zaozhuang, Shandong Province, China, by reverse transcription polymerase chain reaction (RT-PCR) analysis. The complete nucleotide sequences of one isolate from crabapple (ApNMV-Hai) and two isolates from...

Grapevine leafroll disease is one of the most devastating diseases in the global viticulture industry. Grapevine leafroll-associated virus 4 is one of the main pathogens causing this disease. In this study, we obtained the complete genome sequences of two Chinese isolates of GLRaV-4 from ‘Baisainie’...

We evaluated the role of pre-culture on survival rate of in vitro apple plants treated by thermotherapy. Two apple cultivars, Malus×domestica cv. Pink Lady and Huafu, were used in the experiment and both have widely grown in China and infected with Apple chlorotic leaf spot virus (ACLSV) and Apple s...

A total of 288 grapevine samples of 61 different grapevine cultivars, collected from 22 provinces and regions, were analyzed by reverse transcription-PCR (RT-PCR) for the presence of grapevine fabavirus (GFabV). PCR detection results showed the incidences of GFabV were 12.8% (30/235) and 48.1% (25/5...

To develop a rapid and high-sensitivity method for detection of grapevine virus E (GVE), a SYBR Green based real-time fluorescence quantitative RT-PCR method (RT-qPCR) was established. This method could be used to detect GVE specifically, and the sensitivity was about 100 times greater than conventi...
