EPD FOR COMPOSITE CATHODE LAYER IN ALL-SOLID-STATE LITHIUM ION BATTERY BASED ON SULFIDE ELECTROLYTE

All-solid-state lithium ion batteries (LIBs), in which liquid-organic electrolytes are replaced with solid state inorganic electrolytes, are expected to be the optimal rechargeable batteries in the next generation because of their higher energy density, cycle stability and ignition safety. In order to develop all-solid-state LIBs with practical performance, controlling architecture in electrode layer consisting of active materials and solid electrolyte, to obtain good contact of the solids interfaces, with high packing ratio is necessary. However, there are few studies on controlled fabrication of macrostructure. We would like to propose a novel method which is employs electrophoretic deposition (EPD) for preparing composite cathode layer, with LiNi1/3Mn1/3Co1/3O2 (NMC) and 75Li2S-25P2S5 (LPS) used as the cathodic active material and solid electrolyte, respectively. The EPD technique can be used to prepare a cathodic layer with a desired structure because its equipment set up is simple but can be used to obtain complex composite structures.

Pure Choriocarcinoma of Testis with Tumor-Infiltrating Lymphocytes and Granulomas

Pure choriocarcinoma is very rare in the testes, and host immune responses including tumor infiltrating lymphocytes are unusual in choriocarcinoma. This study reports a case of pure testicular choriocarcinoma with extensive lymphocytic infiltrate and granulomatous inflammation. Scrotal ultrasonography revealed a heterogeneous, hyperechoic intratesticular mass. β-human chorionic gonadotropin levels were elevated in a radioimmunoassay. The hemorrhagic and necrotic solid mass was composed of two cell populations - mononuclear pleomorphic cells and intimately admixed multinucleated smudged cells. The tumor cells were positive for cytokeratin 7, epidermal growth factor receptors, human placental lactogen and p57. Many inflammatory cells were present within the tumor. The majority of infiltrating cells were CD8-positive cytotoxic cells, which also expressed granzyme-B and TIA-1. The tumor cells were positive for FasL, but negative for Fas. Therefore, this case seemed to escape the host defense response to the tumor due to the loss of Fas, although the cellular host immune response was still active

Chosen Ciphertext Secure Keyed-Homomorphic Public-Key Encryption

In homomorphic encryption schemes, anyone can perform homomorphic operations, and therefore, it is difficult to manage when, where and by whom they are performed.In addition, the property that anyone can \lq\lq freely\u27\u27 perform the operation inevitably means that ciphertexts are malleable, and it is well-known that adaptive chosen ciphertext (CCA) security and the homomorphic property can never be achieved simultaneously. In this paper, we show that CCA security and the homomorphic property can be simultaneously handled in situations that the user(s) who can perform homomorphic operations on encrypted data should be controlled/limited, and propose a new concept of homomorphic public-key encryption, which we call \emph{keyed-homomorphic public-key encryption} (KH-PKE). By introducing a secret key for homomorphic operations, we can control who is allowed to perform the homomorphic operation. To construct KH-PKE schemes, we introduce a new concept, \emph{transitional universal property}, and present a practical KH-PKE scheme from the DDH assumption. For $\ell$-bit security, our DDH-based KH-PKE scheme yields only $\ell$-bit longer ciphertext size than that of the Cramer--Shoup PKE scheme. Finally, we consider an identity-based analogue of KH-PKE, called \emph{keyed-homomorphic identity-based encryption} (KH-IBE) and give its concrete construction from the Gentry IBE scheme

A Case of Fisher Syndrome Complicated by Maxillary Sinus Cysts

Fisher syndrome (FS) is an autoimmune peripheral neuropathy that occurs in 1 person per 2 million population. The present report is of a patient with FS who presented with diplopia and discomfort of the right cheek and in whom differentiation from maxillary sinus cysts was necessary. The patient was a 43-year-old man with a history of radical surgery of the right maxillary sinus, so we suspected that his symptoms were due to postoperative maxillary sinus cysts. Although computed tomography demonstrated right maxillary sinus cysts, these cysts were not likely to be the cause of the patient\u27s diplopia. Close neurological examination revealed external ophthalmoplegia, cerebellar ataxia, and the absence of a deep tendon reflex; on this basis, a diagnosis of FS was made. Diplopia is caused by various disorders and FS should be taken into consideration when making a differential diagnosis
