Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Aging and Cancer, EarlyView.In patients with malignant ureteral obstruction undergoing percutaneous nephrostomy, sarcopenia defined by a low psoas muscle index was independently associated with poor overall survival on multivariate Cox regression analysis, suggesting that preoperative assessment of psoas muscle index may aid prognostic stratification in this population.

Cryptography as a field of study is exciting because it brings together beautiful mathematics and many cutting-edge areas of computer science and engineering to find solutions that touch all aspects of life in a digital era. In a single day at a cryptography conference, one can hear talks on election security and legislation on regulating encryption ...

The property of nonmalleability for the encryption function \(E\) is a stronger extension of the classic notion of semantic security that was introduced by Goldwasser and Micali. This property is defined as follows. For all polynomial-time computable relations \(R\) seeing \(\alpha\in E(x)\) does not help one to find \(\beta\in E(y)\), \(\beta\neq ...

This paper is concerned with two aspects of cryptography in which the author has been working. One is the Data Encryption Standard (DES), developed at IBM and now in wide use for commercial cryptographic applications. This is a ``private key'' system; the communicants share a secret key, and the eavesdropper will succeed if he can guess this key among ...

It appears to be very difficult to give a formal definition of computational security for public-key cryptography. A slightly different notion, called transient-key cryptography, is defined for which a natural definition of security against chosen-plaintext attacks is given.

AbstractIn the traditional scenario in cryptography there is one sender, one receiver and an active or passive eavesdropper who is an opponent. Large bank transactions require two people to sign, implying two senders. So the power to generate a valid transaction is shared.

Commercialization of cryptography
Information Management & Computer Security, 1997Presents the major approaches for achieving commercial security on the Internet, public key and key escrow. Discusses the implications of (US) legislation putting limitations on the type or strength of key it is best to employ for a given business. Presents the typical modes of delivering authentication and other services.

Cryptography's aim is to construct schemes or protocols that can still accomplish certain tasks even in the presence of an adversary. A basic task in cryptography is to enable users to communicate securely over an insecure channel in a way that guarantees their transmissions' privacy and authenticity.
