    Abstract With the development of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S ribosomal RNA (rRNA) gene sequencing, increasing numbers of new microorganisms are being discovered. In this report, Kerstersia gyiorum was isolated for the first time from the sputum of two elderly patients with neurodegenerative disease, and integrated traditional Chinese and Western medicine was used for treatment. The bacteria’s growth characteristics, biochemical reaction characteristics, sensitivity to antibiotics, and the patients’ treatment are described, with a review of previous reports.

    Abstract Network coding can save the wireless network resources and improve the network throughput by combining the routing with coding. Traditional multisignature from certificateless cryptosystem is not suitable for the network coding environment. In this paper, we propose a certificateless multisignature scheme suitable for network coding (NC-CLMSS) by using the sequential multisignature and homomorphic hash function. NC-CLMSS is based on the CDH and ECDL problems, and its security is detailedly proved in the random oracle (RO) model. In NC-CLMSS, the source node generates a multisignature for the message, and the intermediate node linearly combines the receiving message. NC-CLMSS can resist the pollution and forgery attacks, and it has the fixed signature length and relatively high computation efficiency.

    Abstract Extrapulmonary small cell carcinoma (EPSCC) affecting the external auditory canal (EAC) is uncommon. We herein report a case involving a 56-year-old man with EPSCC of the EAC who had a 48-year history of recurrent purulent discharge in both ears and a 20-day history of right ear pain and hemorrhage followed by incomplete right eyelid closure and an askew mouth. He underwent surgical removal of middle ear granulation tissue, residual ossicles, and a right EAC mass. Postoperatively, pathomorphological examination combined with immunohistochemical staining supported a diagnosis of small cell carcinoma. Radiation therapy at a dose of 60.06 Gy in 33 daily fractions was completed 1 month after surgery, and synchronous etoposide–cisplatin regimen chemotherapy was performed for two cycles and four sequential cycles. One year postoperatively, magnetic resonance imaging showed no tumor in the ear; however, computed tomography showed multiple liver space-occupying lesions that were considered to indicate liver metastasis. Further chemotherapy was performed, but the patient died 15 months postoperatively. This case indicates that timely and accurate chemoradiotherapy is likely the most reasonable approach to EPSCC of the EAC given the aggressiveness of this tumor.

    Abstract Abstract Although switchable adhesive surfaces are important and desirable for soft robotics, it is still challenging to replicate nature's switchable adhesion capability on artificial surfaces, especially for underwater applications. Here polymeric coatings with fingerprint topographies that are capable of switching the surface adhesion upon light illumination are reported. This is achieved via a synergistic combination of surface topographical inversion and spatially selective distribution of adhesive polymers. The surface topographical inversion is accomplished by the anisotropic deformation of the fingerprint‐configured liquid crystal network (LCN) coating upon light‐controlled order parameter modulation. Adhesive and nonadhesive polymers are spatial‐selectively arranged on top of the LCN coating following the alternating homeotropic and planar domains, respectively, where liquid crystal mesogens are orthogonally aligned. The adhesive part is composed of a water‐tolerant adhesive polymer with 3,4‐dihydroxy‐l‐phenylalanine (catechol) groups inspired by mussel byssus. This report presents a dynamic surface with locally alternating nonadhesive indented areas and adhesive elevated areas where the topographical positions can be dynamically changed with light illumination which can serve as smart skins for robotic applications.

    Abstract To determine the best CO2 injection and brine production strategy for achieving both the optimal water production and the optimal CO2 storage capacity while maintaining operational safety in CO2 enhanced brine production, three injection scenarios based on the typical geological parameters of the Junggar Basin in China are compared. They are the sole CO2 injection, sole water production and combined CO2 enhanced water recovery, and for the combined CO2 enhanced water recovery scenario, both the co-production of brine and pre-production of brine are considered. It is found that compared to the pre-production of brine, the combination of pre- and co-production of brine can be more effective in controlling the pressure perturbation and in increasing the CO2 storage capacity. However the volume of co-produced brine plays a smaller role in the pressure build-up. The influence of number of pumping wells is also analyzed. Although increasing the number of wells can enhance the CO2 storage, the economic analysis reveals that the revenue in water production and CO2 storage cannot compensate the expensive investment required in well drilling. The injection strategy is essential to the efficiency of CO2 enhanced water recovery; this paper compares the strategies for pre-production and co-production of brine on CO2 enhanced shale gas recovery. The conclusions given in this paper can serve as a reference for the design engineers interested in CO2 storage with co-production of brine.

    Abstract Single-walled carbon nanotubes (SWCNTs) incorporated with π-conjugated polymers, have proven to be an effective approach in the production of advanced thermoelectric composites. However, the studied polymers are mainly limited to scanty conventional conductive polymers, and their performances still remain to be improved. Herein, a new planar moiety of platinum acetylide in the π-conjugated system is introduced to enhance the intermolecular interaction with the SWCNTs via π–π and d –π interactions, which is crucial in regulating the thermoelectric performances of SWCNT-based composites. As expected, SWCNT composites based on the platinum acetylides embedded polymers displayed a higher power factor (130.7 ± 3.8 μW·m −1 ·K −2 ) at ambient temperature than those without platinum acetylides (59.5 ± 0.7 μW·m −1 ·K −2 ) under the same conditions. Moreover, the strong interactions between the platinum acetylide-based polymers and the SWCNTs are confirmed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) measurements.
