A New Technique in saving Fingerprint with low volume by using Chaos Game and Fractal Theory
Fingerprint is one of the simplest and most reliable
biometric features of human for identification. In this study by
using fractal theory and by the assistance of Chaos Game a new
fractal is made from fingerprint. While making the new fractal by
using Chaos Game mechanism some parameters, which can be
used in identification process, can be deciphered. For this
purpose, a fractal is made for each fingerprint, we save 10
parameters for every fingerprint, which have necessary
information for identity, as said before. So we save 10 decimal
parameters with 0.02 accuracy instead of saving the picture of a
fingerprint or some parts of it. Now we improve the great volume
of fingerprint pictures by using this model which employs fractal
for knowing the personality

Diagnostic Salivary Biomarkers in Traumatic Brain Injury: Narrative Review
Traumatic brain injury (TBI) is a common cause of disability and mortality worldwide. TBI is an acquired brain injury that may be open (penetrating) or closed (non-penetrating) and is be categorized as mild, moderate, or severe, depending on the clinical presentation. Accurate diagnosis at the earliest stages can significantly affect patient discomfort, prognosis, therapeutic intervention, survival rates and recurrence. Whereas traditional CT and MRI techniques for diagnosis are dominant in clinical situations, a promising direction for clinical diagnosis is the use of fluid biomarkers like blood, CSF, urine, and saliva. Fluid biomarkers that may track these injuries and inflammatory processes have been explored for their potential to provide objective measures in TBI assessment. At present, there are limited clinical guidelines available regarding the use of fluid biomarkers in TBI. In recent years, saliva has received significant attention as a biomarker for TBI in clinical practice due to the non-invasive accessibility, cost-effective collection, and consistent relationship with serum. This review examines the utility of saliva biomarkers such as S100B, noncoding RNAs (ncRNAs), extracellular vesicles (EVs), miRNAs levels, microtubule-associated protein tau, alpha-amylase, cortisol, and oxidative stress in TBI. The study highlights the current state of salivary diagnostics, future aspirations, and their potential as the preferred route of TBI detection. The newly developed techniques for salivary analysis of these molecules may help to improve outcomes for TBI through rapid detection current unavailable with serum samples. Future studies via salivary biomarkers will help establish consistent strategies for early diagnosis of TBI and improve treatment outcomes of TBI patients
