Improvement of China's System on Security Assessment of Outbound Personal Data Flow under the Background of CPTPP

With the development of cross-border e-commerce's integration with the global economy, the cross-border data flow is playing an increasing important role in international economy and trade, and the smoothness of it directly or indirectly affects the improvement of the digital economy. Many countries or regions have established their own legal regulation systems for outbound data. Now China is the largest retail export economy in cross-border electronic commerce in the world, it application to join the Comprehensive and Progressive Trans-Pacific Partnership Agreement (CPTPP) is not smooth, and its data cross-border rules are quite different from CPTPP clauses, so it is difficult to align with them. Among them, the security assessment of outbound personal data flow system currently implemented in China is a major factor that makes connecting the cross-border personal data flow rules of China with CPTPP cross-border personal data flow clauses more difficult. By comparing this system in China with the cross-border personal data flow regulation system in the United States and the European Union, as well as the relevant provisions of CPTPP, this paper points out that there are some problems in this system in China, such as vague definition of the basic concept "important data" and excessive burden on data processors, and puts forward some legislative improvement measures to solve these existing problems, such as clarifying "important data", constructing a classification and grading system for cross-border data flow, and reshaping the distribution system of compliance responsibility for safety assessment.

Innovative Approaches to Beam Forming Antenna Array Systems with Adaptive Partial Update NLMS Algorithms

Improvements in interference cancellation, energy economy, spectrum efficiency, and system security are among the most pressing needs for today's wireless networks. One effective technique for this is the use of a Beamforming Array Antennas (BAA). However, the complexity of the Beamforming (BF) network, the long convergence time, and the large number of adjustable weight coefficients, all work against full band BAA. The key innovation and contribution of this research was to use Partial Update (PU) instead of full band adaptive algorithms, as no previous attempt had been made to do so. A subset of the array's elements, rather than all of them, will be connected to by PU methods. This allows the system to reduce the number of active antennas across all cells while maintaining high efficiency, and low cost. In this research, a new architectural model was proposed that makes use of PU adaptive algorithms, to reduce the required number of phase shifters (PSs), and hence base station antennas. For the most part, we will be discussing PU Normalized Least Mean Square (PU NLMS) algorithms like M-max NLMS, Periodic-NLMS, and Stochastic-NLMS. Using a Uniform Linear Array (ULA) Antennas in a simulation environment, we find that the, in terms of Mean Square Error (MSE), convergence rate, and steady-state error, it is evident that all PU NLMS algorithms (with the exception of Periodic-NLMS) had performed close, and approximately equivalent performance to the full band NLMS algorithms. In other hands, these PU algorithms maintain the radiation pattern with as little change from the original (distortion-free) as possible and symmetrical of the array, while. fewer elements are needed to produce the same amount of radiation. Reducing the number of required coefficients N to M (M = 5; M: Number of coefficients to be update per iteration) compared to the full update method (N = 8), to obtain the Reduction ratio 38%.

Pengembangan Pengelolaan Dana Zakat di LAZISMU Sebagai Peningkatan Kualitas Organisasi PCIM (Pimpinan Cabang Istimewa Malaysia)

How important essence is in the Muhammadiyah movement, zakat and the generous dimension are important, strategic and effective agendas. Lazismu is the leader. Zakat is one of the pillars of Islam which guides Muslims in implementing it. Zakat is an activity to cleanse oneself of possessions to carry out social responsibilities. Zakat management has different forms of supervision, so that sometimes there are different perceptions about the zakat operating system, where zakat can change it towards improving the economy. Furthermore, the data collected will become part of the large zakat data which can lead to improvements in the people's economy. The problem that occurs in PCIM Malaysia is that the zakat collection that has been carried out is still not significant in relation to the residents of Kampung Baru, Kuala Lumpur. This is shown because the level of community involvement in the zakat management system at PCIM is not optimal. The meeting, which lasted for two hours, discussed various aspects related to zakat in the Muhammadiyah Association and also aspects of digitalization in the management, communication and distribution of zakat funds. This activity uses an advanced approach to the community through broadcasting or preaching to the residents of Kampung Baru, Kuala Lumpur. It is hoped that this community service program will provide awareness to people who already have the obligation to pay zakat so that the quantity of zakat collection in PCIM will increase.

The Effect of Polarized Training Intensity Distribution on Maximal Oxygen Uptake and Work Economy Among Endurance Athletes: A Systematic Review.

High-intensity training (HIT) has commonly been the most effective training method for improvement in maximal oxygen uptake (VO2max) and work economy, alongside a substantial volume of low-intensity training (LIT). The polarized training model combines both low- and high-intensity training into a specific training intensity distribution and has gained attention as a comprehensive approach. The objective of this review was to systematically search the literature in order to identify the effects of polarized training intensity distribution on VO2max, peak oxygen uptake (VO2peak), and work economy among endurance athletes. A literature search was performed using PubMed and SPORTDiscus. A total of 1836 articles were identified, and, after the selection process, 14 relevant studies were included in this review. The findings indicate that a polarized training approach seems to be effective for enhancing VO2max, VO2peak, and work economy over a short-term period for endurance athletes. Specifically, a training intensity distribution involving a moderate to high volume of HIT (15-20%) combined with a substantial volume of LIT (75-80%) appears to be the most beneficial for these improvements. It was concluded that polarized training is a beneficial approach for enhancing VO2max, VO2peak, and work economy in endurance athletes. However, the limited number of studies restricts the generalizability of these findings.

Effects of longitudinal bending stiffness and midsole foam on running energetics

Advanced footwear technology has become commonplace in the competitive running world. However, a systematic exploration of the effects of each of the primary components has not yet been presented. Our goal was to quantify running economy and step parameters in four different shoe conditions: PEBA shoes with plate, PEBA shoes without plate, EVA shoes with plate and EVA shoes without plate. Participants ran at 14 km/h (n = 8 males) or 12 km/h (n = 6 females) on a treadmill. The shoe order was randomly assigned for the four shoe conditions, where the participants wore each shoe twice in a mirrored order. There was a significant reduction in metabolic power (1.0%) associated with the presence of a plate, as well as a similar reduction based on foam type (1.0%). However, there was no significant interaction between presence of plate and foam type. Adding a plate significantly reduced metabolic power for EVA by 1.3% but not for PEBA. PEBA foam significantly reduced metabolic power by 1.3% in shoes without a plate, but not for the shoes with a plate. Step frequency and contact time were similar between shoes and not correlated to running economy improvements. Starting from a baseline condition with traditional foam without a plate, either adding a plate or using PEBA foam improved running economy with a similar amount (1.3%). Adding the alternate second feature non-significantly improved running economy with an additional 0.6%. The benefit of both technologies combined (1.9%) was smaller than the sum of its parts (1.3% each).
