Signal Sequences and Sorting Receptors01:41

Signal Sequences and Sorting Receptors

Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...
Processes of Self-Presentation01:29

Processes of Self-Presentation

Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or conventions...
Classification of Signals01:30

Classification of Signals

In signal processing, signals are classified based on various characteristics: continuous-time versus discrete-time, periodic versus aperiodic, analog versus digital, and causal versus noncausal. Each category highlights distinct properties crucial for understanding and manipulating signals.
A continuous-time signal holds a value at every instant in time, representing information seamlessly. In contrast, a discrete-time signal holds values only at specific moments, often denoted as x(n), where...
Signal and System01:26

Signal and System

A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional signals...

Social Foundations of Self IV: Self in Digital Communication

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...
Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Area of Science:

  • Computational Mathematics
  • Mathematical Biology
  • Information Security

Background:

  • Predator-prey models, specifically the Beddington-de Angelis type, exhibit complex dynamics.
  • Self-organizing patterns can emerge from small perturbations in such systems.
  • Steganography, the art of hiding information, faces challenges in secure data embedding.

Purpose of the Study:

  • To propose a novel secure steganographic communication algorithm.
  • To investigate the security of using evolving patterns in a predator-prey model for data hiding.
  • To develop a robust method for secure visual communication.

Main Methods:

  • Utilizing a Beddington-de Angelis predator-prey model with self- and cross-diffusion.
  • Analyzing the evolution of self-organizing patterns from small initial perturbations.
  • Employing statistical techniques to assess pattern interpretability and security.
  • Implementing a dot-skeleton representation of secret images for perturbation.

Main Results:

  • Evolving patterns from small initial perturbations are not secure for steganography, as secret image contours can be retrieved.
  • A secure visual communication technique is demonstrated by using the self-organizing pattern evolved from initial states perturbed by the secret image's dot-skeleton.
  • This alternative approach effectively protects both the secret image and the communicating parties.

Conclusions:

  • Simple perturbation-based pattern generation in predator-prey models is insufficient for secure steganography.
  • A novel secure steganographic method is presented, leveraging the unique properties of self-organizing patterns.
  • The proposed algorithm offers a promising solution for secure visual communication by enhancing data protection.
