Conventional watermarking techniques based on echo hiding provide many benefits, but also have several disadvantages, for example, a lenient decoding process, weakness against multiple encoding attacks, etc. In this paper, to improve the weak points of conventional hiding, we propose time-spread as an alternative single in hiding. Spreading time domain is achieved by using pseudonoise (PN) sequences. By spreading echo, amplitude each can be reduced, i.e., energy becomes small, so that...
The purpose of this study was to assess the initial clinical response superselective intraarterial infusion cisplatin for treating stage III and IV squamous cell carcinoma mouth.Thirteen patients received therapy. tumors were located in tongue (n = 7), gingiva 3), buccal mucosa 1), hard palate floor mouth 1). A coaxial technique used place microcatheters lingual, facial, inferior alveolar, buccinator, distal internal maxillary arteries, depending on tumor location. feeding vessels identified...
Audio watermarking techniques are used to embed extra information, typically relating copyrights, into audio signals. In some applications, embedding of multiple watermarks in a single multimedia content is required. Considering an actual situation, it might be necessary up three kinds information as watermarks, i.e., copyright management copy control and fingerprints. For this purpose, new technique capable based on phase modulation proposed paper. The idea utilizes the insensitivity human...
Abstract Force transmission through adherens junctions (AJs) is crucial for multicellular organization, wound healing and tissue regeneration. Recent studies shed light on the molecular mechanisms of mechanotransduction at AJs. However, canonical model fails to explain force when essential proteins module are mutated or missing. Here, we demonstrate that, in absence α-catenin, β-catenin can directly functionally interact with vinculin its open conformation, bearing physiological forces....
Integrin-based cell adhesions (IACs) serve as primary sites where piconewton-scale actomyosin-generated mechanical forces are transmitted to the extracellular matrix (ECM), generating traction that drive cell-ECM responses including adhesion, migration, and mechano-signaling. Talin, a large (270 kDa) cytosolic adaptor protein, is principal force-transmission protein in integrin-based adhesions, containing multiple mechanosensitive domains protein-protein interaction orchestrate molecular...
Audio watermarking techniques are used to embed extra information, typically relating copyrights, into audio signals. In some applications, embedding of multiple watermarks in a single multimedia content is required. Considering an actual situation, it might be necessary up three kinds information as watermarks, i.e., "copyright management information," "copy control and "fingerprints." For this purpose, new technique capable based on phase modulation proposed paper. The idea utilizes the...
Although gross tumor volume (GTV) at the primary site can predict local control of head-and-neck squamous cell carcinoma (SCC) in patients who are treated with organ-preservation therapy, GTV assessment does not eliminate substantial interobserver variation.To evaluate whether F-18-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed (CT) fused imaging provides additional information for assessment.We obtained FDG-PET/CT images on 20 SCC. All had undergone preoperative...
Based on the spatial masking phenomenon and Ambisonics, a watermarking technique for audio signals is proposed. Ambisonics well known to encode reproduce information related sound. The proposed method exploits this feature of Ambisonics. A watermark represented as slightly rotated version original sound scene. In another scenario in which Ambisonic are synthesized from mono or stereo signals, watermarks embedded near signal by adding small copy host signal. This presents important advantage...
Tumors at the cranial base in 2 cats (a 9 1/2-year-old, castrated male Chinchilla and a 7-year-old, American shorthair) were diagnosed as malignant craniopharyngioma. The tumor lesion was histopathologically divided into four parts: 1) small acinus part, which relatively large cells with pale cytoplasm composed acini; 2) duct cuboidal ducts; 3) cyst there cysts lined flat cells; 4) pavement multiangular-shaped proliferated pattern. epithelial of some parts positive for keratin by...
To evaluate MR findings in early (T1 and T2 stages) glottic carcinomas the predictive value of imaging for rate 5-year local control with radiation therapy.Eighty-three patients were prospectively examined at 1.5 T. investigation included unenhanced T1-weighted, T2-weighted, dynamic contrast-enhanced T1-weighted images. Three presumed advanced diseases on initially treated total laryngectomy excluded from study. The remaining 80 therapy curative intent. Tumor detectability, size relationship...
A pitch-scaling modification of a watermarked signal is severe attack on audio watermarking techniques. In particular, techniques using pseudonoise (PN) sequence as secret key are fragile in the face this because desynchronization between original and embedded PN sequences. We, therefore, propose log-scaling watermark detection method to cope with problem. This based general logarithm operation frequency or quefrency axis decoding process. also advantageous that no other embedding process...
Epithelial tubules, consisting of the epithelial cell sheet with a central lumen, are basic structure many organs. Mechanical forces play an important role in tubulogenesis; however, little is known about mechanisms controlling mechanical during tubule morphogenesis. Solo (also as ARHGEF40) RhoA-targeting guanine-nucleotide exchange factor that involved force-induced RhoA activation and stress fiber formation. binds to keratin-8/keratin-18 (K8/K18) filaments, this interaction plays crucial...
Background: Although intraarterial chemotherapy has been used to treat head and neck cancers, some cases have shown poor response. If we can predict the response this therapy on MRI, individual treatment plans may be altered most appropriate form of treatment. Purpose: To evaluate whether MRI histological preoperative chemoirradiation in patients with cancer mouth. Material Methods: This study comprised 29 consecutive 30 oral cancers. All underwent tumor resection after infusion conformal...
