The present research investigates consumers' behavioral intention towards cashless modes of payment in Vietnam with mediating factors such as green finance perception. Based on the theory planned behavior and perceived benefits study seeks to compare functional, economic, psychological social influencing attitude, self-control beliefs subjective norms, acceptance systems. engaged a survey 355 respondents offered measurement model analysis results relation between variables following partial...
Esophageal cancer (EC) ranks as the 7th most prevalent form of and 6th leading cause cancer-related mortality globally. Neoadjuvant therapy, encompassing neoadjuvant chemotherapy or chemoradiotherapy, has shown promise in reducing staging EC mitigating risk early systemic spread. This study seeks to assess safety viability implementing chemoradiotherapy (nCRT) conjunction with radical esophagectomy surgery for Vietnamese patients diagnosed locally advanced EC. Safety was evaluated based on...
Background E-portfolios are evolving electronic/online resources that record, store, and archive the artifacts of learning reflection for an individual learner. They have become more popular nowadays. This study aimed to evaluate knowledge attitudes dental students regarding use e-portfolios as a tool assessment, learning, professional development in education. Methods Three hundred seven completed five-point Likert scale questionnaire, which was administered using Google Forms (Google,...
The paper proposes an active constellation modification technique to lower peak-to-average power ratio (PAPR) for orthogonal frequency division multiplexing (OFDM) signals. First, the authors introduce some algorithms reduce computational complexity while ensuring reduced PAPR performance, including optimal non-iterative ACE algorithm, suboptimal extension (ACE) and constrained clipping noise filtering (CCNF) algorithm. Next, a hybrid its hardware architecture are introduced that combines...
In this paper, the authors introduce a new clipping-and-filtering method for peak-to-average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) signals. The proposed algorithm aims to achieve four primary purposes. First, it eliminates out-of-band components clipping noise avoid adjacent channel leakage. Second, constrains constellation distortion in square-shaped region while maintaining certain distances among points signal space. Third, increases PAPR...
Partial Transmit Sequence (PTS) technique is one of effective techniques for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. In the conventional PTS (C-PTS) approaches, a large number big size inverse fast Fourier transform (IFFT) blocks are required, which results high complexity and difficulties hardware implementation. this paper, an optimization scheme without transmitting side information phase factor recovery algorithms...
This study was conducted to determine the phytochemical composition of bitter melon seeds (Momordica charantia L.) grown in Long An province (Vietnam), investigate optimal conditions for lipid extraction, and evaluate extracted lipid’s quality. The had a moisture content 5.27%, total ash 1.85%, flavonoid 91.10 mg/100 g, polyphenol 478.95 g. were also free highly toxic metals such as lead cadmium. Using Soxhlet method, extraction achieved with material-to-solvent ratio 1:80 (w/v) over 4...
The “Ball Levitation” experiment can be easily recognized, like iFly in Singapore, and is greatly integrated into industrial fields such as flow control systems, aerodynamic testing, the oil gas industry, HVAC etc. Therefore, it utilized university laboratories for student exploration of non-linear technology. main objective this through position ball which measured by an ultrasonic sensor to execute PWM blower fan order speed one so that stabilized consistently at a specific height. Despite...
Inverted pendulum (IP) is a single input-multi output (SIMO) nonlinear system that popular in laboratories of control engineering. In this paper, we propose structure the PID method – most industry - for cart and pole (C&P) system- kind IP. case, suitable can help input-single (SISO) linear controllers to balance well. By combination, be used stabilize model at equilibrium point. This controller proven work well simulation. Therefore, also present an experimental which created from...
Ovarian cancer with breast metastasis is an exceedingly rare entity. We hereby reported a case of ovarian presenting synchronous metastasis. report 39-year-old patient who was diagnosed FIGO stage IV cancer, pleural effusion and suspected lesion in the breast. Biopsies showed invasive carcinoma, immunohistochemistry stains biopsy specimen were positive for PAX-8, CA-125 markers, negative P53, SMA, Her2/neu, Mammaglobin. Immunohistochemistry results combined diagnosis helped confirm origin...
Single-cell analysis provides a more information-rich approach to disease diagnosis than traditional methods.At the cellular level, electrical properties have been established as reliable markers, capable of revealing variations between individual cells.This study focuses on optimising geometry coplanar micro-electrode structure for detecting human lung adenocarcinoma cells (A549) within fluid channel using impedance flow cytometry.A549 were chosen due their frequent occurrence in cancer...
In this paper, first, the authors evaluate efficiency of algorithms for interleaved partition-based PTS (Partial Transmit Sequence) scheme using only a small-sized single inverse fast Fourier transform block and binary phase sequence. Then we implement practical hardware scheme. The architecture is conducted on FPGA 16-bit fixed-point representation. Simulation experimental results indicate that peak-to-average-power ratio reduction our DVB-T2 system almost as high in traditional (T-PTS),...
In this paper, the authors propose alternative filters to improve spectral properties of filtered orthogonal frequency division multiplexing (filtered-OFDM) candidate waveform for new wireless systems (fifth generation (5G) and next generation). The effectiveness proposed is validated through extensive simulations experiments in 5G scenarios at 2K. results show that can containment capability a filtered-OFDM signal by more than 100 dB when compared an OFDM signal. meet optimization...
