Camille Saint-Säens' Piano Concerto No. 5 in F Major, Opus 103: An Analytical Study of Form, Compositional Techniques, and a Performance Perspective
The majority of books about Saint-Säens cover his life, compositions, contemporaries, and French music in general. Although his life is well documented, most sources present only brief analyses of his works; there is not one single comprehensive and exhaustive study of the Piano Concerto in F Major, Opus 103, available in the current literature. This study aims at filling the gap by providing other musicians interested in performing this piece with an initial study-guide. The research for this study focuses on several aspects of Saint-Säens' music. The currently available literature and past research is thoroughly examined, appraised, and quoted when relevant to the discussion. The original score of the concerto is analyzed regarding its form, compositional style, and performance indications. Diagrams, charts, and musical examples are presented to illustrate and substantiate the researcher's conclusions. Chapter I presents the topic and purpose of this study, a brief biography of Saint-Säens, a chronological overview of his five piano concertos, and the historical background of the Piano Concerto No. 5 in F Major, Opus 103. Chapter II presents a formal analysis and a compositional analysis of Opus 103. Chapter III presents a perspective of Saint-Säens playing style and performance recommendations by the author. Chapter IV concludes this study by determining the importance of Opus 103 in piano literature and by explaining the reason that performers with professional aspirations should consider including this concerto in their repertoire
Toxicity Studies on Secretio Bufonis: A Traditional Supplement in Asia
AbstractObjectivesThis study was performed to investigate the toxicity of Secretio Bufonis (SB) on male mice and assess its no-observed-adverse-effect-level (NOAEL).Materials and MethodsAfter feeding an aqueous solution of SB extracts to mice for either 1 or 8 weeks, their blood and urine were assayed and their liver and kidney morphology examined. The numerical data was analyzed by the Mann-Whitney U-test and analysis of variance test.ResultsMice administered SB in 50 mg/kg/day for 1 week had higher heart weights and higher aspartate transaminase activities; those administered SB in 0.01 and 0.05 mg/kg/day for 8 weeks had lower creatinine concentrations; and those administered SB in 0.5 mg/kg/day for 8 weeks had higher brain weights and higher blood urea nitrogen.ConclusionsThe extracts of SB had cardiac toxicity in the short term and hepatotoxicity in the long term. The NOAEL of the extract was under 5 mg/kg/day for 1 week and under 0.25 mg/kg/day for 8 weeks
GPS-GLASS: Learning Nighttime Semantic Segmentation Using Daytime Video and GPS data
Semantic segmentation for autonomous driving should be robust against various
in-the-wild environments. Nighttime semantic segmentation is especially
challenging due to a lack of annotated nighttime images and a large domain gap
from daytime images with sufficient annotation. In this paper, we propose a
novel GPS-based training framework for nighttime semantic segmentation. Given
GPS-aligned pairs of daytime and nighttime images, we perform cross-domain
correspondence matching to obtain pixel-level pseudo supervision. Moreover, we
conduct flow estimation between daytime video frames and apply GPS-based
scaling to acquire another pixel-level pseudo supervision. Using these pseudo
supervisions with a confidence map, we train a nighttime semantic segmentation
network without any annotation from nighttime images. Experimental results
demonstrate the effectiveness of the proposed method on several nighttime
semantic segmentation datasets. Our source code is available at

Efficient Conversion Method from Arithmetic to Boolean Masking in Constrained Devices
A common technique employed for preventing a side channel analysis is boolean masking. However, the application of this scheme is not so straightforward when it comes to block ciphers based on Addition-Rotation-Xor structure. In order to address this issue, since 2000, scholars have investigated schemes for converting Arithmetic to Boolean (AtoB) masking and Boolean to Arithmetic (BtoA) masking schemes. However, these solutions have certain limitations. The time performance of the AtoB scheme is extremely unsatisfactory because of the high complexity of where is the size of addition bit. At the FSE 2015, an improved algorithm with time complexity based on the Kogge-Stone carry look-ahead adder was suggested. Despite its efficiency, this algorithm cannot consider for constrained environments. Although the original algorithm naturally extends to low-resource devices, there is no advantage in time performance; we call this variant as the generic variant.
In this study, we suggest an enhanced variant algorithm to apply to constrained devices. Our solution is based on the principle of the Kogge-Stone carry look-ahead adder, and it uses a divide and conquer approach. In addition, we prove the security of our new algorithm against first-order attack. In implementation results, when and the register bit size of a chip is , or , we obtain \%, \%, or \% improvement, respectively, over the results obtained using the generic variant. When applying those algorithms to first-order SPECK, we also achieve about \% improvement. Moreover, our proposal extends to higher-order countermeasures as previous study
Effect of supply chain structure and power dynamics on R&D and market performances

Effect of supply chain structure and power dynamics on R&D and market performances
This study is the first investigating the effect of supply chain structure and players’ power dynamics on a supply chain’s R&D and market performances. We consider a three-stage supply chain, consisting of a R&D firm, a manufacturer, and a seller. We develop six supply chain models based on various structures and power dynamics, and reveal important implications by comparing the models. R&D performance is a function of supply chain structure; an integrated supply chain can expect improved performance. The selling price is a function of power dynamics, and is higher when R&D has bargaining power. Market and profit performances are higher in an integrated, manufacturer-led supply chain. The manufacturer’s role must be revisited; due to its location in the middle of the supply chain, the manufacturer can directly control the overall chain. On the other hand, a R&D firm could innately be associated with marginalization issues. Therefore, it is important for the R&D firm to have a systematic understanding of the entire system. This study contributes to the literature and practice by not only bridging the gap in the previous studies but also offering important managerial implications
The value of type IV collagen immunohistochemical staining in the differential diagnosis of autoimmune subepidermal bullous diseases
Autoimmune subepidermal bullous diseases (AISBDs) exhibit various clinical presentations, histological appearances, prognoses, and responses to treatment. Many diagnostic techniques, such as direct immunofluorescence (IF), indirect salt-split skin IF, and enzyme-linked immunosorbent assays, are used in the differential diagnoses of AISBDs. However, these techniques require fresh frozen tissue, expensive laboratory equipment, and sophisticated laboratory techniques. The purpose of this study was to evaluate the value of type IV collagen immunohistochemical (IHC) staining for the differential diagnosis of AISBDs. Paraffin-embedded blocks of skin biopsies were selected from 28 patients with autoimmune subepidermal bullous diseases. Among these 28 cases, 24 patients exhibited bullous pemphigoid (BP), 2 exhibited epidermolysis bullosa acquisita (EBA), 1 exhibited linear immunoglobulin A dermatosis (LAD), and 1 exhibited bullous systemic lupus erythematosus (BSLE). Sections were stained for type IV collagen and examined to determine the location of type IV collagen in the subepidermal blister. Type IV collagen positivity was observed on the base of the subepidermal blister in patients with BP (24 of 24 cases) and LAD (1 of 1 case). Staining was observed on the roof of the blister in patients with EBA (2 of 2 cases) and BSLE (1 of 1 case), and irregular staining was also observed on the base in patients with EBA. In conclusion, type IV collagen IHC staining is a simple and useful diagnostic technique for the differential diagnosis of AISBDs. .042) compared with controls. The filiform papillae had partially or completely regenerated in 85.7% of cases in the test group and in 23.1% of the controls (P=0.001). Red patches with raised keratotic rims may have healed spontaneously and reappeared in constantly changing patterns that are typical for MG. This phenomenon was not observed in patients supplemented with zinc, and new atrophy areas occurred in only one case. Low-dose zinc gluconate supplementation may have a positive therapeutic effect on tongue epithelium regeneration and symptomatology in patients with MG. in our region were consistent with those from other studies. </p

Biochemical characterization of a recombinant Japanese encephalitis virus RNA-dependent RNA polymerase
<p>Abstract</p> <p>Background</p> <p>Japanese encephalitis virus (JEV) NS5 is a viral nonstructural protein that carries both methyltransferase and RNA-dependent RNA polymerase (RdRp) domains. It is a key component of the viral RNA replicase complex that presumably includes other viral nonstructural and cellular proteins. The biochemical properties of JEV NS5 have not been characterized due to the lack of a robust <it>in vitro </it>RdRp assay system, and the molecular mechanisms for the initiation of RNA synthesis by JEV NS5 remain to be elucidated.</p> <p>Results</p> <p>To characterize the biochemical properties of JEV RdRp, we expressed in <it>Escherichia coli </it>and purified an enzymatically active full-length recombinant JEV NS5 protein with a hexahistidine tag at the N-terminus. The purified NS5 protein, but not the mutant NS5 protein with an Ala substitution at the first Asp of the RdRp-conserved GDD motif, exhibited template- and primer-dependent RNA synthesis activity using a poly(A) RNA template. The NS5 protein was able to use both plus- and minus-strand 3'-untranslated regions of the JEV genome as templates in the absence of a primer, with the latter RNA being a better template. Analysis of the RNA synthesis initiation site using the 3'-end 83 nucleotides of the JEV genome as a minimal RNA template revealed that the NS5 protein specifically initiates RNA synthesis from an internal site, U<sub>81</sub>, at the two nucleotides upstream of the 3'-end of the template.</p> <p>Conclusion</p> <p>As a first step toward the understanding of the molecular mechanisms for JEV RNA replication and ultimately for the <it>in vitro </it>reconstitution of viral RNA replicase complex, we for the first time established an <it>in vitro </it>JEV RdRp assay system with a functional full-length recombinant JEV NS5 protein and characterized the mechanisms of RNA synthesis from nonviral and viral RNA templates. The full-length recombinant JEV NS5 will be useful for the elucidation of the structure-function relationship of this enzyme and for the development of anti-JEV agents.</p
