Abstract: A thin film transistor includes an active layer located over a substrate, a first gate stack including a stack of a first gate dielectric and a first gate electrode and located on a first surface of the active layer, a pair of first contact electrodes contacting peripheral portions of the first surface of the active layer and laterally spaced from each other along a first horizontal direction by the first gate electrode, a second contact electrode contacting a second surface of the active layer that is vertically spaced from the first surface of the active layer, and a pair of second gate stacks including a respective stack of a second gate dielectric and a second gate electrode and located on a respective peripheral portion of a second surface of the active layer.

Abstract: Provided is an underground pipe leak detection system, including a sensing device, a storage device, and a processing device. The sensing device is used for collecting a voice signal from an underground pipe during a time period. The storage device is used for storing a voice dataset, and storing the voice signal transmitted by the sensing device. The processing device may access the storage device. The processing device is configured to execute the following operations: training a classification model using the voice dataset; extracting features of the voice signal; inputting the features of the voice signal into the classification model that has been trained to determine if there is a leak in the underground pipe.

Abstract: An electronic device and a method for detecting apnea are provided. The method includes: transmitting a wireless signal to a human subject, receiving an echo corresponding to the wireless signal, and obtaining channel state information (CSI) from the echo; generating a detection result according to the CSI; outputting the detection result. Here, the detection result indicates whether an apnea event has occurred on the human subject.

Abstract: The present invention discloses preparation and application of a kind of biodegradable-material-made microsphere vascular embolus that contains liposome-encapsulated cytokines. The present invention is technologically characterized by encapsulation of liposome-wrapped immunocytokines such as IL-2, TNF and interferon by sodium polysaccharide or gelatin, which is extracted from natural alga and is good at biodegradability and biocompatibility. Owing to the encapsulation procedures, cytokine microspheres can take shape measuring 50-75 ?m, 75-150 ?m, 100-200 ?m, 200-300 ?m, 200-450 ?m, 100-300 ?m, 300-500 ?m, 500-700 ?m, and 700-900 ?m. The microsphere preparations are good targeting medication for embolism treatment and immunochemotherapy of animals loaded with human hepatocarcinoma and cervical cancer, as well as human suffering from late-stage or recurrent liver cancer, renal tumors, bladder cancer, colon carcinoma and rectal cancer.

Abstract: The present disclosure relates to a kind of sodium alginate microsphere vascular embolus that contains water-soluble drug and preparation and application thereof. The embolus preparation falls into dry microsphere type and wet one that are made of degradable materials. The drug carrier can be sodium alginate, human serum albumin, chitosan or sodium hyalurate, solidifying and forming microsphere together with calcium ion solution under presence of static charge. The microsphere can have a diameter in the range of 20-1000 ?m and can be divided into a wide variety of sizes in case of need. The present disclosure adopts raw materials that are good at mechanical strength, bio-compatibility, bio-degradability and stability.
