Integrative systems‐level analysis reveals a contextual crosstalk between hypoxia and global metabolism in human breast tumors

open access: yesMolecular Oncology, EarlyView.
Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

One to One Identification of Cryptosystem Using Fisher’s Discriminant Analysis

open access: yesInternational Journal of Networked and Distributed Computing (IJNDC), 2018
Distiguishing analysis is an important part of cryptanalysis. It is an important content of discriminating analysis that how to identify ciphertext is encrypted by which cryptosystems when it knows only ciphertext.

Cryptanalysis of QTL Block Cipher

open access: yes, 2017
QTL is an ultra-lightweight block cipher designed for extremely constrained devices. The cipher has two versions, QLT-64 and QTL-128 supporting key lengths of 64 and 128 bits, respectively. In this paper, we present the first third party cryptanalysis of QTL. We first introduce related key distinguishers for full versions of the cipher.

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance

open access: yesMolecular Oncology, EarlyView.
In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...

Proposal of a New Block Cipher reasonably Non-Vulnerable against Cryptanalytic Attacks [PDF]

open access: yesIJCSI International Journal of Computer Science Issues, Vol. 9, Issue 1, No 1, January 2012, 2012
This paper proposes a new block cipher termed as "Modular Arithmetic based Block Cipher with Varying Key-Spaces (MABCVK)" that uses private key-spaces of varying lengths to encrypt data files. There is a simple but intelligent use of theory of modular arithmetic in the scheme of the cipher.

Integrative analysis of circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients: a comprehensive approach

open access: yesMolecular Oncology, EarlyView.
This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

BLOSTREAM: A HIGH SPEED STREAM CIPHER [PDF]

open access: yesJournal of Engineering Science and Technology, 2017
Although stream ciphers are widely utilized to encrypt sensitive data at fast speeds, security concerns have led to a shift from stream to block ciphers, judging that the current technology in stream cipher is inferior to the technology of block ciphers.

A Time-Success Ratio Analysis of wPRF-based Leakage-Resilient Stream Ciphers [PDF]

open access: yesarXiv, 2015
Weak pseudorandom functions (wPRFs) found an important application as main building blocks for leakage-resilient ciphers (EUROCRYPT'09). Several security bounds, based on different techniques, were given to these stream ciphers. The security loss in these reduction-based proofs is always polynomial, but has not been studied in detail.
