11A4111R1111N32This paper discusses prime numbers that are (resp. are not) congruent numbers. Particularly the only case not fully covered by earlier results, namely primes of the form p = 8k +1, receives attention.doi:10.2989/16073606.2021.1977410Tim EvinkJaap TopJakob Dirk TopTaylor And FrancisQuaestiones mathematicae: Journal...
试题来源: 解析 C 正确答案:C解析:The non-prime numbers between 40 and 50 are 42, 44, 45, 46, 48, and 49. (Remember, the non-inclusive means we don’t include the 40 and 50.) Add them all up and we get 274.反馈 收藏
The biggest misconception about my role is...that I'm able to clone or replicate hair when performing surgery. Hair transplant surgery currently involves the redistribution of hair from an area of abundance (commonly the back and sides of the scalp) to an area lacking it,...
Recently, higher-order topological insulators (HOTIs) have been introduced, and were shown to host topological corner states under the theoretical framework of Benalcazar-Bernevig-Hughes. Here we unveil some topological effects in HOTIs by studying the t
Further, it is known that about 50% of those exposed to HPV infection may not mount an immune response [19] which may explain the lack of difference in MFI levels. In addition, our study had few numbers that self reported sexual activity. Finally, self reporting sexual activity may not ...
Long noncoding RNAs (lncRNAs) are linked to cancer via pathogenic changes in their expression levels. Yet, it remains unclear whether lncRNAs can also impact tumour cell fitness via function-altering somatic “driver” mutations. To search for such drive

First, pCKb11 was added to the F-PPPD nanoparticles at different weight ratios (pCKb11:F-PPPD) of 1:0, 1:12.5, 1:25 and 1:50. Subsequently, these samples were subjected to electrophoresis in a 1% (w/v) agarose gel (Invitrogen, USA) in Tris-acetate-EDTA (TAE) buffer (pH 7.4; ...
(Fig.1b–d). Their exquisite complexity is reminiscent of high-magnification images of snowflakes; however, the diatom frustules are created by genetically encoded developmental programs, and as such are highly reproducible and characteristic for many of the 10,000 to 100,000 estimated species [3...
