Three types of bidirectional leader development in triggered lightning flashes.

Eight cases of bidirectional leader (BL) development in artificially triggered lightning flashes are reported with synchronous high-speed camera images and electric field signals. Based on optical progressing characteristics, the eight cases can be divided into three types: a reflection type, a discontinuity type, and an inducement type. For the reflection type, the tail of a dart leader may begin to extend backward when the leader's head reaches a branch point, or the top of the exploded triggering wire.

Ascorbic acid-induced fiber-scrolling of titanium carbide TiCT MXene.

Changing the morphology of two-dimensional materials often offers an efficient and effective means to exploit their electronic and mechanical properties. Two-dimensional materials such as graphene can be scrolled into one-dimensional fibers simple sonication. Unfortunately, scrolling MXene nanosheets into fibers is quite challenging, especially TiCT composed of three layers of titanium atoms and two layers of carbon atoms.

Cell Division Cycle-Associated Genes Are Potential Immune Regulators in Nasopharyngeal Carcinoma.

Background: Cell division cycle-associated (CDCA) gene family is essential to cell cycle regulation. Numerous studies have illuminated that dysfunction of CDCA genes may not only lead to uncontrolled cell proliferation resulting in tumorigenesis but also influence immune cell infiltration in tumors. However, the role of the CDCA gene family on the prognosis and immune infiltration in nasopharyngeal carcinoma (NPC) remains to be unclear.

Rationale and design of a prospective, multicenter, randomized controlled trial of postoperative venous thromboembolism prophylaxis in Chinese adult patients with inguinal hernia (CHAT-3 trial).

Background: Venous thromboembolism (VTE) is one of the most common causes of preventable harm for patients in hospitals. Nearly half of all VTE events was estimated to occur after surgical procedure. The Caprini risk score is the most extensively used risk assessment tool in predicting postoperative VTE, which is too complicate for surgeons to use properly in their clinical practice.

Negentropy Spectrum Decomposition and Its Application in Compound Fault Diagnosis of Rolling Bearing.

The rolling bearings often suffer from compound fault in practice. Compared with single fault, compound fault contains multiple fault features that are coupled together and make it difficult to detect and extract all fault features by traditional methods such as Hilbert envelope demodulation, wavelet transform and empirical node decomposition (EMD). In order to realize the compound fault diagnosis of rolling bearings and improve the diagnostic accuracy, we developed negentropy spectrum decomposition (NSD), which is based on fast empirical wavelet transform (FEWT) and spectral negentropy, with cyclic extraction as the extraction method.
