The androgenic gland(AG) is an important endocrine gland for male reproductive function in crustaceans. In the present study, we investigated the histological characteristics of the androgenic gland of peppermint shrimp, Lysmata wurdemanni. The peppermint shrimp matures as male first, then some individuals may become euhermaphrodite after several moltings(transitional phase). Euhermaphrodite-phase shrimp acts as male at intermolts. However, it can be fertilized as a female immediately after molting. Considering the male reproductive function acts in its lifespan except for at larval stages, and female reproductive system starts to develop at transitional phase, we hypothesized that AG activity might be reduced to allow and promote vitellogenesis onset in early transitional phase and the following euhermaphrodite phase. So AG cell structure might be different in three phases in L. wurdemanni. The results showed that AG exists in the male in transitional and euhermaphrodite phases. The gland cell clusters surrounding the ejaculatory ducts locate at the roots of the fifth pereopods. The nucleus diameters are similar in the three phases while the nucleus-to-cell ratio is the lowest in euhermaphrodite phase. Our results indicated that for the individuals that will become euhermaphrodite, the cellular structure of AG changes since transitional phase. Male reproductive function which is still available in euhermaphrodite-phase shrimp should be due to the existence of the gland.

White-box cryptography(WBC) aims to resist attacks from attackers who can control all the implementation details of cryptographic schemes. In 2009, Saxena et al. proposed a fundamental of white-box cryptography via the notion "white-box property"(WBP). Under this model, they proved that there do not exist obfuscators that can satisfy every security notion for a program(the negative result). On the other hand,they proved that there exists an obfuscator satisfying WBP for some security notion(the positive result). These contributions provide us a general cognition of WBC, which is big progress for the theoretical research. To better understand them, we make discussion on each result and achieve some new results. For the negative result, we prove that insufficiently secure obfuscator is the real cause of the negative result. We point out that the security of a white-box scheme cannot be guaranteed if it is instantiated by a less secure obfuscator, since the obfuscator used in their proof does not satisfy the "Virtual Black-box Property" with auxiliary input. From our proof,we also conclude that the notion WBP is equal to "Virtual Black-box Property with auxiliary input". For the positive result, we prove that security notion under black-box model should not be used in white-box context without any modification; although the positive result is meaningful, it is unlikely to prove that an obfuscator satisfies WBP for IND-CPA, since the security notion "IND-CPA" is under black-box model, which has different adversary with WBP.

It seems that the wealth of information revealed by the multi-messenger observations of the binary neutron star(NS)merger event,GW170817/GRB 170817A/kilonova AT2017gfo,places irreconcilable constraints to models of the prompt emission of this gamma-ray burst(GRB).The observed time delay between the merger of the two NSs and the trigger of the GRB and the thermal tail of the prompt emission can hardly be reproduced by these models *** argue that the merger remnant should be an NS(last for,at least,a large fraction of 1 s),and that the difficulty can be alleviated by the delayed formation of the accretion disk due to the absorption of high-energy neutrinos emitted by the NS and the delayed emergence of effective viscosity in the ***,we extend the consideration of the effect of the energy deposition of neutrinos emitted from the *** the NS is the central object of a GRB with a distance and duration similar to that of GRB 170817A,thermal emission of the thermal bubble inflated by the NS after the termination of accretion may be *** our scenario is verified,it would be of interest to investigate the cooling of nascent NSs.

The mono-frequency peak luminosity and the corresponding photon energy of the time-integrated （L~, Eg） and peak time （L~, ffp） vfv spectra were derived for a sample of 38 redshift-known Fermi GRBs by fitting the spectra with the Band function. It was found that Ept is generally consistent with Ep, and Lp is averagely three times larger than Lp. The slope of the Lp1 -Etp relation was consistent with that of the Lps - Eps relation. The photon indices in the peak time spectrum, particularly, the index of the low energy end was, were statistically larger than that in the time-integrated spectrum. These results indicate that Lp and Ep are dominated by Lp1 and Ept, respectively. The difference of the spectral indices between the time-integrated and peak time spectra may be because of the overlap effect of a series of time-resolved spectra within a GRB. Our simulations, which were based on the observed spectral evolution and correlation between the energy flux and the peak energy within individual GRBs support our speculations. The Lt - Et, relation may be less contaminated by the overla!a effect, and it would may be an intrinsic feature of radiation ohvsics.

Graphene nanoribbons （GNRs） with a non-zero bandgap are regarded as a promising candidate for the fabrica- tion of electronic devices. In this study, large-scale solution synthesis of narrow GNRs was firstly achieved by the intramolecular cyclodehydrogenation of kinked tetraphenylethene （TPE） polymer precursors prepared by A2B2-type Suzuki-Miyaura polymerization. After the cyclization reaction, the nanoribbons have a better conjugation than the twisted polymer precursor, resulting in obvious red shift in UV/vis absorption and photoluminescence （PL） spectra. The efficient formation of conjugated nanoribbons was also investigated by Raman, FTIR spectroscopy, and micro- scopic studies. Furthermore, such structurally well-defined GNRs have been successfully developed for top-gated field-effect transistor （FET） by directly solution processing. The AFM images show that the prepared-GNRs thin films form crystalline fibrillar intercalating networks, which can effectively facilitate the charge transport. These FET devices with ion-gel gate dielectrics exhibit low-voltage operation （〈5 V） with excellent mobility up to 0.41 cm2·V-1·s-1 and an on-off ratio of 3 × 104, thus opening up new opportunities for flexible GNRs-based electronic devices.
