Biometric techniques are gaining importance for personal authentication and identification as compared to the traditional authentication methods. Biometric templates are vulnerable to variety of attacks due to their inherent nature. When a person’s biometric is compromised his identity is lost. In contrast to password, biometric is not revocable. Therefore, providing security to the stored biom...

BACKGROUND To objectively compare the early changes in vault over time following implantation of an Implantable Collamer Lens without (ICL V4) and with (ICL V4c) a central hole and the respective factors affecting vault change in moderate to high myopia. METHODS This prospective study comprised of 38 eyes of 38 patients implanted with ICL V4 and 39 eyes of 39 patients implanted with ICL V4c i...

conclusions along with the technological advancement, different materials are employed according to the size of the cranium defect and the age of the case. the application of split costa cranioplasty for the small cranium defects in the region of patient’s face is the method with the least possibility of complications, and its cosmetic and functional results are quite promising. introduction os...

A 41-year-old man presented with consciousness disturbance and right hemiparesis. Computed tomography showed a hematoma in the frontal lobe. Left carotid angiography showed a dural arteriovenous fistula (AVF) located in the cranial vault, supplied by the left middle meningeal artery, and drained directly into the cortical vein adjacent to the superior sagittal sinus. Emergency decompressive cra...

The structure of rat liver vault ribonucleoprotein particles was examined using several different staining techniques in conjunction with EM and digestion with hydrolytic enzymes. Quantitative scanning transmission EM demonstrates that each vault particle has a total mass of 12.9 +/- 1 MD and contains two centers of mass, suggesting that each vault particle is a dimer. Freeze-etch reveals that ...

Decentralized cryptocurrencies rely on participants to keep track of the state of the system in order to verify new transactions. As the number of users and transactions grows, this requirement places a significant burden on the users, as they need to download, verify, and store a large amount of data in order to participate. Vault is a new cryptocurrency designed to minimize these storage and ...

The vault particle, with a molecular weight of about 10 MDa, is the largest ribonucleoprotein that has been described. The X-ray structure of intact rat vault has been solved at a resolution of 3.5 Å [Tanaka et al. (2009), Science, 323, 384-388], showing an overall barrel-shaped architecture organized into two identical moieties, each consisting of 39 copies of the major vault protein (MVP). Th...

We investigate the security of a privacy enhancing technique for fingerprint authentication known as fuzzy fingerprint vault. This technique is based on the fuzzy vault of Jules and Sudan, a scheme that allows error tolerant authentication, while preserving the privacy of the reference data. We explore if and under what circumstances a secure fuzzy fingerprint vault can be implemented. We deriv...

Spreader grafts (SGs) have been widely used for both aesthetic and functional reasons to prevent middle vault collapse and treat internal nasal valve insufficiency. Although SG precise fixation can be easily achieved in open rhinoplasty, the difficulties of SG placement in closed rhinoplasties can be discouraging. In the present report, we describe a new custom-made SG (called "rail spreader") ...

The crooked or twisted nose results from a complex deformity of the bony pyramid, the upper and lower cartilaginous vaults, and the septum and causes functional and aesthetic problems. The forces of scar contracture coupled with long-standing cartilage deformation may make the crooked nose resistant to conventional surgical intervention. The middle vault of the nose may exhibit deformities that...
