We introduce the concept of a quantum “seal” and investigate its feasibility. We define a seal as a state provided by Alice to Bob along with a set of instructions which Bob can follow in order to “break the seal” and read the classical message stored inside. We define two success criteria for a seal: the probability Bob can successfully read the message if he follows Alice’s instructions witho...

Wear and failure of mechanical seals may be critical in certain applications and should be avoided. Large relative misalignment between the seal faces is the most likely cause for intermittent contact and the increased friction that eventually brings failure. Adjustment of the seal clearance is probably the most readily implemented method of reducing the relative misalignment and eliminating se...

Abundance trends of Hawaiian monk seals Monachus schauinslandi at 6 subpopulations throughout the Northwestern Hawaiian Islands (NWHI) have fluctuated considerably during the past 5 decades. Direct human impacts have been widely accepted as the primary cause of previous monk seal population declines and, consequently, much conservation effort has focused on minimizing these threats. Yet climate...

Fault sealing is one of the key factors controlling hydrocarbon accumulations and trap volumetrics and can be a significant influence on reservoir performance during production. Fault seal is, therefore, a major exploration and production uncertainty. We introduce a systematic framework in which the geologic risk of faults trapping hydrocarbons may be assessed. A fault may seal if deformation p...

This paper describes a new electronic official seal stamping based on Group Signature, USB Key. Bill/Contract in Ecommerce must be seal stamped to gain tamper proof and nonrepudiation. The seal stamping control is designed based on the certificate-based public key. This technique is more efficient for generating and verifying individual/group signatures in terms of computational efforts and com...

The purpose of this study is to assess the possibility of implementing an online advertising strategy using a well-known third-party privacy seal located on the order page of an unfamiliar online retailer. An online experiment was conducted with 223 participants using a 2 (third-party seal: present vs. absent)×2 (purchase-decision involvement: low vs. high)×2 (disposition to trust: low vs. high...

Abstract Introduction: Thickness of a coronal seal barrier is an important factor for preventing microleakage. The aim of this in vitro study was to compare the sealing ability of two different thicknesses of calcium Enriched Mixture (CEM) cement as a coronal seal barrier.   Methods: A total of 40 canals of extracted maxillary central incisors were instrumented and obturated using lateral compa...

Introduction: The healing process after surgery is a challenging issue for surgeons. Various materials and techniques have been developed to facilitate this process and reduce its period. Fibrin adhesives are often used in cardiothoracic and vascular surgery to seal diffuse microvascular bleeding and in general and plastic surgery to seal wound borders. This Case report and literature review ...

The colostrum trypsin inhibitor (CTI) gene and transcript were cloned from the Cape fur seal mammary gland and CTI identified by in silico analysis of the Pacific walrus and polar bear genomes (Order Carnivora), and in marine and terrestrial mammals of the Orders Cetartiodactyla (yak, whales, camel) and Perissodactyla (white rhinoceros). Unexpectedly, Weddell seal CTI was predicted to be a pseu...
