Assume that 8 people are seated around a table and we want to enumerate the number of ways that they can be permuted such that neighbors are no more neighbors after the rearrangement. Of course the answer depends on the topology of the table: if the table is a circle then it is easy to check by a simple computer program that the permutations that verify this property are 2832, if it is a long b...

After publication of this article [1], we noted errors to the " body weight " row of Table three. The values for the controls of Δ 1 (wk 0 ~ wk 4) and Δ 2 (wk 0 ~ wk 8) should be negative (please see Table 1 below, a corrected version of Table three). Reference 1. Zhu W, et al: Calcium plus vitamin D3 supplementation facilitated fat loss in overweight and obese college students with very-low ca...

An image enhancement algorithm for low-vision television viewing was developed. The algorithm enhances the images in the JPEG/MPEG domain by weighting the quantization table. The advantages of our algorithm are threefold: (1) Low computation (only a change of the 8× 8 quantization table in the decoding stage); (2) Suitable for real–time application; and (3) easily manipulated by individual user...

In the original article, the reference for Bista et al. (2017) was incorrectly written as “Carvalho, G. R., Walsh, K., Seymour, M., Hajibabaei, M., Lallias, D., Christmas, M., et al. (2017). Annual time-series analysis of aqueous eDNA reveals ecologically relevant dynamics of lake ecosystem biodiversity. Nat. Commun. 8, 1–11. doi: 10.1038/ncomms14087.” It should be “Bista, I., Carvalho, G. R., ...

In [1], some input data required to calculate the long-term rain attenuation probability distributions for two sites (namely, Canberra and New Norcia) were mistaken. They were the long-term rain rate probability distribution and the precipitation height, both given by the ITU-R. For Canberra, the correct precipitation height (given by the ITU-R) is 3.688 km, instead of 2.870, for New Norcia is ...

Color quantization is often used to convert 24-bit RGB images to 8-bit palette-table images. However, in some cases, the imposed 8 bits per pixel may be too stringent to adequately represent the image. For other images, 8 bits per pixel are unnecessarily generous. For image storage and transmission, it is important to compress an image as much as possible without exceeding an allowable level of...
