A reconstruction algorithm for compressive quantum tomography using various measurement sets

Compressed sensing (CS) has been verified that it offers a significant performance improvement for large quantum systems comparing with the conventional quantum tomography approaches, because it reduces the number of measurements from O(d2) to O(rd log(d)) in particular for quantum states that are fairly pure. Yet few algorithms have been proposed for quantum state tomography...

Effect of Unplanned Therapy on the Prognosis of Patients with Extremity Osteosarcoma

Unplanned therapy for extremity osteosarcoma can result in erroneous surgical procedures and lack of neoadjuvant chemotherapy before the first operation. Our aim was to compare the prognosis between patients with extremity osteosarcoma who received unplanned therapy and those who received standard treatment. This was a retrospective review of patients with extremity osteosarcoma...

Investigation of rheo-diecasting mold filling of semi-solid A380 aluminum alloy slurry

The rheo-diecasting mold filling capacity and the microstructure of the semi-solid A380 aluminum alloy slurry were investigated. The results show that the mold filling capacity was strengthened with increasing pouring temperature or increasing injection pressure. Under certain process parameters, the mold cavity was fully filled. However, the mold filling capacity decreased with...

Landmark-Based Route Recommendation with Crowd Intelligence

Route recommendation is one of the most widely used location-based services nowadays, as it is vital for nice-driving experience and smooth public traffic. Given a pair of user-specified origin and destination, a route recommendation service aims to provide users with the routes of the best travelling experience according to given criteria. However, even the routes recommended by...

Compensatory variances of drug-induced hepatitis B virus YMDD mutations

Although the drug-induced mutations of HBV have been ever documented, the evolutionary mechanism is still obscure. To deeply reveal molecular characters of HBV evolution under the special condition, here we made a comprehensive investigation of the molecular variation of the 3432 wild-type sequences and 439 YMDD variants from HBV genotype A, B, C and D, and evaluated the co...

Traditional Chinese medicine combination therapy for patients with steroid-dependent ulcerative colitis: study protocol for a randomized controlled trial

Background Approximately 20% of patients with ulcerative colitis become steroid dependent. Azathioprine is recommended in steroid-dependent ulcerative colitis, but its side effects limit its use. Chinese herbal medicine has been widely used to treat ulcerative colitis in China. However, its effectiveness in steroid-dependent patients has not been evaluated. This study aims to...

Surgical treatment for pelvic giant cell tumor: a multi-center study

Background The purpose of this study was to discuss the clinical results which related to the location of giant cell tumors (GCTs) in the pelvis so as to determine the ideal surgical treatment protocol. Methods We report 29 cases who accepted surgical treatment from five clinical centers during the last 12 years. All patients were divided into three groups according to tumor...

Health-Related Quality of Life in Chinese Patients with Mild and Moderately Active Ulcerative Colitis

Background Ulcerative colitis (UC) impairs the health-related quality of life (HRQOL). The difference in HRQOL between patients with mild and moderately active UC is not well-defined. Few studies have been conducted to explore the factors that influence HRQOL in Chinese patients. Our study aims were to (1) compare HRQOL of mildly active UC patients with moderate patients; (2...

Study on the non-contact FBG vibration sensor and its application

A non-contact vibration sensor based on the fiber Bragg grating (FBG) sensor has been presented, and it is used to monitor the vibration of rotating shaft. In the paper, we describe the principle of the sensor and make some experimental analyses. The analysis results show that the sensitivity and linearity of the sensor are −1.5 pm/μm and 4.11% within a measuring range of 2 mm–2...

Continuous Finite-Time Terminal Sliding Mode IDA-PBC Design for PMSM with the Port-Controlled Hamiltonian Model

Finite-time control scheme for speed regulation of permanent magnet synchronous motor (PMSM) is investigated under the port-controlled Hamiltonian (PCH), terminal sliding mode (TSM), and fast TSM stabilization theories. The desired equilibrium is assigned to the PCH structure model of PMSM by maximum torque per ampere (MTPA) principle, and the desired Hamiltonian function of...
