We achieved transient detection of the terahertz pulse time-domain waveform of the living HeLa cells. The system was employed for the terahertz detection of trace living cervical cancer cells. In this article, we developed a set of terahertz single measurement system based on the tilt wave front of grating pulse technique. However, in the life environment, the dynamic time scale of cell-environment interaction and structural conformation change of biological macromolecules are within picosecond to millisecond, and water has strong absorption to terahertz wave, which has become the bottleneck problem for the detection of cells and biological macromolecules by terahertz technology. The photonic energy of terahertz wave is in the same order of magnitude as the rotational and vibrational energy levels of organic and biological macromolecules, so it has unique advantages in detecting cells and biological macromolecules.

The vice minister section is blank.Ĭo-published with SpyTalk, where Jeff Stein leads an all-star team of veteran investigative reporters, writers, and subject-matter experts who will take you behind the scenes of the national security state. Under “personnel developments,” it notes the corruption investigation against another former vice minister, Ma Jian, who was sentenced to life in prison in 2018. Meanwhile, the Chinese State Council’s official web page listing the top personnel in the Ministry of State Security no longer lists any vice ministers working under MSS minister Chen Wenqing. Back in 2010, IO reported that Dong carried out orders from superiors in Beijing to arrest “four Japanese employees of the Fujita Corporation who were filming in a forbidden military zone.” The move was seen at the time as a power play by State Security against then-President Hu Jintao. “He previously headed the Guoanbu in the region of Hebei, which has produced many of Xi's securocrats,” the publication reported in 2018. Army Medical Research Institute of Infectious Diseases (USAMRIID) personnel detailed to DIA have corroborated very technical details of information provided by the defector,” it said.Īccording to the authoritative Paris-based newsletter Intelligence Online, Dong is “close to” Chinese President Xi Jinping. “Sources say the level of confidence in the defector’s information is what has led to a sudden crisis of confidence in Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. Without naming Dong, the pro-Trump web site Red State reported June 4 on a high-level defection from China, saying the Defense Intelligence Agency had received information from him that Beijing is covering up biological warfare research at the Wuhan lab, and advanced its story to question the integrity of Dr. She is allegedly the former spouse of a senior Alibaba executive, Jiang Fan, who heads TMall, China’s big Amazon-like business. ![]() A half dozen experts on Chinese intelligence queried by SpyTalk said they had no information to share on Dong’s alleged defection.Ĭhinese-language press stories also claim that Dong’s daughter Yang defected with him from Hong Kong on or about Feb. It typically does not comment on defectors. The State Department did not respond to a request for comment by press time. In short, if true, this is potentially significant but not a game changer.” “While significant and certainly useful for our intelligence efforts,” she added, “one high-level defection will not drastically change our understanding or approach to China. Mollie Saltskog, a senior intelligence analyst with The Soufan Group who earned a master’s degree in global affairs from Tsinghua University in Beijing, also urged caution, saying the rumors of defections surface regularly. Han, a pro-democracy activist with the Washington, D.C.-based Citizen Power Initiative for China group, “a straight shooter, not known to exaggerate in any way or form… trusted for his integrity.” It happens all the time” in the information warfare between Beijing and anti-communist overseas Chinese. Former Pentagon, State Department, and CIA expert Nicholas Eftimiades, author of Chinese Espionage: Operations and Tactics, called the report “exactly what it is, a rumor. ![]()
