Whether it is possible to construct a chosen ciphertext secure (CCA secure) public key encryption (PKE) scheme only from a chosen plaintext secure (CPA secure) one is a fundamental open problem, and the best known positive results regarding this problem are the constructions of so-called bounded CCA secure schemes. Since we can achieve the best possible security in the bounded CCA security noti...
AIMS To investigate the specific expression of insulin-like growth factor binding protein-1 (IGFBP-1) in ovarian clear cell adenocarcinoma (CCA). METHODS AND RESULTS Immunohistochemistry and in situ hybridization for IGFBP-1 were performed in normal endometrium, placenta, and 100 surgically resected cases of ovarian cancer including 31 CCAs and 69 non-CCAs. Immunohistochemistry for hepatocyte...
Removal of predators can have strong indirect effects on primary producers through trophic cascades. Crustose coralline algae (CCA) are major primary producers worldwide that may be influenced by predator removal through changes in grazer composition and biomass. CCA have been most widely studied in Caribbean and temperate reefs, where cover increases with increasing grazer biomass due to remov...
Transcription in eukaryotes produces a number of long noncoding RNAs (lncRNAs). Two of these, MALAT1 and Menβ, generate a tRNA-like small RNA in addition to the mature lncRNA. The stability of these tRNA-like small RNAs and bona fide tRNAs is monitored by the CCA-adding enzyme. Whereas CCA is added to stable tRNAs and tRNA-like transcripts, a second CCA repeat is added to certain unstable trans...
The Common Component Architecture (CCA) provides a means for software developers to manage the complexity of large-scale scientific simulations and to move toward a plug-and-play environment for high-performance computing. In the scientific computing context, component models also promote collaboration using independently developed software, thereby allowing particular individuals or groups to ...
Canonical correlation analysis (CCA) is a classical tool in statistical analysis to find the projections that maximize the correlation between two data sets. In this work we propose a generalization of CCA to several data sets, which is shown to be equivalent to the classical maximum variance (MAXVAR) generalization proposed by Kettenring. The reformulation of this generalization as a set of co...
Methionine aminopeptidase-2 (MetAP2) is over-expressed in several cancers, including the cholangiocarcinoma (CCA). We reported previously suppressive effects of fumagillin, a MetAP2 inhibitor, on growth of CCA cell lines. In the present study, we evaluated the anti-proliferative and anti-invasive activities of TNP-470, a fumagillin analogue with higher MetAP2 inhibitory activity, on CCA cell li...
Kurosawa and Desmedt proposed an efficient hybrid encryption scheme(KD04) which is secure against adaptive chosen ciphertext attacks(IND-CCA) although the underlying KEM(key encapsulation mechanism) is not IND-CCA secure[11]. We show a variant of KD04 which is IND-CCA secure when the the underlying DEM part is IND-CCA secure. We need a DEM built from one-time symmetric encryption scheme and a M...
Suppression of protein kinase A regulatory subunit 1 alpha (PRKAR1A) has been proven to inhibit cholangiocarcinoma (CCA) cell growth and enhance apoptosis. In the present study, we aimed to determine synergistic and/or additive effects of chemotherapeutic agents, including protein kinase inhibitors (i.e. sorafenib, sunitinib, gefitinib, Met inhibitor) and conventional chemotherapeutic drugs (i....
We address the problem of integrating textual and visual information in vector space models for word meaning representation. We first present the Residual CCA (R-CCA) method, that complements the standard CCA method by representing, for each modality, the difference between the original signal and the signal projected to the shared, max correlation, space. We then show that constructing visual ...
