PHÂN TÍCH KHẢ NĂNG ỨNG DỤNG CÔNG NGHỆ BLOCKCHAIN VÀO CHUỖI CUNG ỨNG DẦU TRÀM TẠI HUẾ

On the basis of referenced studies on blockchain technology and the applicability of blockchain in supply chain management of agricultural products, the study analyzes the applicability of blockchain technology in melaleuca oil supply chain in Hue. The study applies both qualitative and quantitative research methods. The results of the qualitative research step help outline a new research framework with 6 groups of aspects to be assessed. Next, the study surveys 215 units/individuals involved in the melaleuca oil supply chain, the sample is selected by simple random method. The obtained results show that the groups of aspects related to readiness (REA), compatibility (COM), cooperatability (COO) and legal environment (LEG) are trickiest obstacles to the applicability of blockchain technology. In addition, the difference test shows that each group of units/individuals in the supply chain has different levels of readiness for the application of new technology.Trên cơ sở tham khảo các nghiên cứu về công nghệ chuỗi khối (blockchain) và khả năng ứng dụng của blockchain trong quản lý chuỗi cung ứng sản phẩm nông nghiệp, nghiên cứu được thực hiện nhằm phân tích khả năng ứng dụng công nghệ blockchain vào chuỗi cung ứng dầu tràm tại Huế. Nghiên cứu áp dụng đồng thời cả hai phương pháp nghiên cứu định tính và định lượng. Kết quả bước nghiên cứu định tính giúp phác thảo nên được khung phân tích mới với 6 nhóm khía cạnh cần đánh giá. Tiếp đến, nghiên cứu khảo sát 215 các đơn vị/cá nhân tham gia vào chuỗi cung ứng dầu tràm, mẫu được chọn theo phương pháp ngẫu nhiên đơn giản. Kết quả thu được chỉ ra rằng: các nhóm khía cạnh liên quan đến điều kiện sẵn có (REA), khả năng tương thích (COM) và môi trường pháp lý (LEG) là những trở ngại lớn nhất cho việc ứng dụng công nghệ blockchain. Ngược lại, khả năng hợp tác (COO), môi trường xã hội (SOC), và môi trường cạnh tranh (CE) là những nền tảng quan trọng thúc đẩy khả năng ứng dụng blockchain. Ngoài ra, kiểm định sự khác biệt cho thấy, mỗi nhóm đơn vị/ cá nhân trong chuỗi cung ứng có mức độ sẵn sàng khác nhau cho việc ứng dụng công nghệ mới

Universality in odd-even harmonic generation and application in terahertz waveform sampling

Odd-even harmonics emitted from a laser-target system imprint rich, subtle information characterizing the system's dynamical asymmetry, which is desirable to decipher. In this Letter, we discover a simple universal relation between the odd-even harmonics and the asymmetry of the THz-assisted laser-atomic system -- atoms in a fundamental mid-IR laser pulse combined with a THz laser. First, we demonstrate numerically and then analytically formulize the harmonic even-to-odd ratio as a function of the THz electric field, the source of the system's asymmetry. Notably, we suggest a scaling that makes the obtained rule universal, independent of the parameters of both the fundamental pulse and atomic target. This universality facilitates us to propose a general pump-probe scheme for THz waveform sampling from the even-to-odd ratio, measurable within a conventional compact setup

The 2nd Workshop on Maritime Computer Vision (MaCVi) 2024

The 2nd Workshop on Maritime Computer Vision (MaCVi) 2024 addresses maritime computer vision for Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicles (USV). Three challenges categories are considered: (i) UAV-based Maritime Object Tracking with Re-identification, (ii) USV-based Maritime Obstacle Segmentation and Detection, (iii) USV-based Maritime Boat Tracking. The USV-based Maritime Obstacle Segmentation and Detection features three sub-challenges, including a new embedded challenge addressing efficicent inference on real-world embedded devices. This report offers a comprehensive overview of the findings from the challenges. We provide both statistical and qualitative analyses, evaluating trends from over 195 submissions. All datasets, evaluation code, and the leaderboard are available to the public at https://macvi.org/workshop/macvi24.Comment: Part of 2nd Workshop on Maritime Computer Vision (MaCVi) 2024 IEEE Xplore submission as part of WACV 202

Mitochondria and Reactive Oxygen Species in Aging and Age-Related Diseases

Aging has been linked to several degenerative processes that, through the accumulation of molecular and cellular damage, can progressively lead to cell dysfunction and organ failure. Human aging is linked with a higher risk for individuals to develop cancer, neurodegenerative, cardiovascular, and metabolic disorders. The understanding of the molecular basis of aging and associated diseases has been one major challenge of scientific research over the last decades. Mitochondria, the center of oxidative metabolism and principal site of reactive oxygen species (ROS) production, are crucial both in health and in pathogenesis of many diseases. Redox signaling is important for the modulation of cell functions and several studies indicate a dual role for ROS in cell physiology. In fact, high concentrations of ROS are pathogenic and can cause severe damage to cell and organelle membranes, DNA, and proteins. On the other hand, moderate amounts of ROS are essential for the maintenance of several biological processes, including gene expression. In this review, we provide an update regarding the key roles of ROS–mitochondria cross talk in different fundamental physiological or pathological situations accompanying aging and highlighting that mitochondrial ROS may be a decisive target in clinical practice
