Web-based User Authentication and Access Control: An Enhanced Multi-Factor Biometric Cryptographic Scheme Based on Client File and S13 Quantum Key Distribution Protocol

open access: yesJournal of High-Frequency Communication Technologies
Several remote user authentication schemes have been proposed using external memory and smart cards. Smart card-based schemes have user mobility and deployment problems, and those based on external memory have a tamper resistance problem.

LSM Index with Common Components for Historical Data Indexing

open access: yesСовременные информационные технологии и IT-образование, 2022
The modern era is characterized by an explosive growth in the amount of data stored and processed. In such circumstances, the performance of storing and indexing of data in external memory become especially important. There are a variety of applications

External Memory Pipelining Made Easy With TPIE

open access: yes, 2017
When handling large datasets that exceed the capacity of the main memory, movement of data between main memory and external memory (disk), rather than actual (CPU) computation time, is often the bottleneck in the computation.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

(Semi-)External Algorithms for Graph Partitioning and Clustering

open access: yes, 2014
In this paper, we develop semi-external and external memory algorithms for graph partitioning and clustering problems. Graph partitioning and clustering are key tools for processing and analyzing large complex networks.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Enhancing Oncological Care for India's Aging Population: Addressing the Complex Needs of Older Adults With Cancer

open access: yesAging and Cancer, EarlyView.
Aging‐associated physiological and molecular alterations pose significant challenges in cancer management among India's elderly. Limited geriatric oncology expertise, financial constraints, and inadequate specialized care exacerbate disparities. Strategic expansion of insurance coverage, integration of palliative care, and infrastructural advancements ...

Thermodynamic limits to information harvesting by sensory systems

open access: yes, 2015
In view of the relation between information and thermodynamics we investigate how much information about an external protocol can be stored in the memory of a stochastic measurement device given an energy budget.

Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.
