The numerous works on media retargeting call for a thorough and comprehensive survey for reviewing and categorizing existing works and providing insights that can help future design of retargeting approaches and its applica- tions. First, we present the basic problem of media retarget- ing and detail state-of-the-art retargeting methods devised to solve it. Second, we review recent works on objective quality assessment of media retargeting, where we find that although these works are designed to make the objective assessment result in accordance with the subjective evaluation, they are only suitable for certain situations. Considering the subjective nature of aesthetics, designing objective assessment metric for media retargeting could be a promising area for investiga- tion. Third, we elaborate on other applications extended from retargeting techniques. We show how to apply the retarget- ing techniques in other fields to solve their challenging prob- lems, and reveal that retargeting technique is not just a simple scaling algorithm, but a thought or concept, which has great flexibility and is quite useful. We believe this review can help researchers and practitioners to solve the existing problems of media retargeting and bring new ideas in their works.

Impossible differential cryptanalysis is an important approach to evaluate the security of block ciphers. In EUROCRYPT 2016, Sun, et al. proved that there exists no impossible differential longer than four rounds for the AES structure where S-boxes are arbitrary. In DCC 2019, Wang,et al. proved that any differential is possible for 5-round AES, assuming that the round keys are independent and uniformly random. In ASIACRYPT 2020, Hu, et al. used automatic search to show that there exists no one-byte active impossible differential for 5-round AES-128 considering the relations of 3-round keys. By algebraic methods, this paper theoretically proves that there exists no one-byte active impossible differential for 5-round AES even considering the relations of all round keys. Firstly,the authors prove the independence of ten bytes in the consecutive four round keys under the key schedule of AES-128. Then 5-round AES is decomposed to three subfunctions and the propagations of the considered differences in these subfunctions are discussed. Finally, the authors prove that the considered differential trails can be connected by the ten bytes of round keys. Furthermore, for any given one-byte active differential, there are at least 2^(51) master keys such that the differential is possible for 5-round AES-128.

Atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured during various seasons at six different cities/locations in Qingdao alongshore. The annual average PAHs concentration ranged from 16 ng/m3 (at a clean com- pared site) to 308 ng/m3 (in an industry site). The average total particulate PAHs concentration was 74.5 ng/m3 with a higher concentration of particulate PAHs in winter. Based on a year-round dataset, the sources of PAHs in the air of Qingdao were drawn by principal factor analysis and correlation analysis. The results indicated that vehicle emissions and oil burning were the main source of PAHs in Qingdao alongshore.
