English Image Description Image description The image presents a symbolic visualization of the Singularity Number (o) using an aviation metaphor. A commercial aircraft accelerates along a runway at sunset, approaching a marked threshold labeled "V1". In aviation, V1 represents the critical decision speed beyond which a takeoff can no longer be safely aborted. In this visual metaphor, the runway represents the trajectory of a complex adaptive system under increasing optimization pressure. The dashed yellow line labeled V1 symbolizes the Singularity Number (o)-the critical threshold at which the balance between structural compression and adaptive capacity is irreversibly lost. Once this threshold is crossed, the system can no longer return to its previous stable state. Collapse is no longer caused by external shocks alone but becomes a mathematically inevitable outcome of the system's internal dynamics. The image illustrates the central concept of the Compression-Resonance-Tension Index (CRTI) framework: complex systems often fail not because of randomness or chaos, but because excessive optimization gradually eliminates adaptive reserves until a point of no return is reached.🖖

Every #complexSystem has a #V1 moment …

like an aircraft on the runway, a point where turning back is no longer possible.

The #SingularityNumber (σ) measures that point of no return, when excessive optimization makes collapse mathematically inevitable.

Delighted to present our work at @iitmadras.bsky.social Open House 2026, CoE Critical Transitions in Complex Systems. We showcased research on complex systems and live-demonstrated thermoacoustic instability. Great enthusiasm and insightful questions from visitors

Assume gains are private, but losses are shared. What happens if this rule governs a system of interacting open subsystems exchanging resources with the environment? The system will have a sharp, switch-like state transition. Check our new pre-print arxiv.org/abs/2512.22839

In biology, we’re still busy naming T cells and debating EMT or autophagy — a bit like arguing over bird names while the real wonder lies in understanding how they fly.

If I want to teach undergraduate students about driven non-equilibrium systems, which two toy models should I choose? The mathematics must be intuitive, and the simulations must be easy. What do you suggest? #statmech #physics #complexsystem #systemsbiology

Engineering Basal Cognition: Minimal Genetic Circuits for Habituation, Sensitization, and Massed–Spaced Learning Cognition is often associated with complex brains, yet many forms of learning—such as habituation, sensitization, and even spacing effects—have been observed in single cells and aneural organisms.

Does a cell have a 'mind' - say a proto-mind or basal cognition? Although it was once a fringe idea, recent experimental and mathematical works are accumulating in its support. Here is an interesting recent work: www.biorxiv.org/content/10.1... #complexsystem #systemsbiology #sysbio

Before physics* found symmetry, biology was already breaking it.

A conjecture that's eating me: Before brains learned to think, cells were already making Bayesian inferences.

US Electric Grid Faces Multiple Threats to Reliability as Complexity Mounts The US electric grid faces increasing complexity and multiple threats to reliability, including fuel supply, market design, regulations, and permitting processes. A lack of unified responsibility across Congress, FERC, and States contributes to inaction and inconsistent policies, further exacerbated by state-level actions impacting interstate grid reliability. Recent warnings from NERC and the National Academies of Science highlight the fragility of the grid. Solutions are prioritized based on reliability value and expediency. Highest priority actions include expediting generator winterization, ensuring natural gas fuel assurance (requiring Congressional action), and overhauling state permitting processes to reduce interstate reliability impacts. Medium priority actions involve unleashing flexible demand, finishing generator interconnection reforms, safeguarding against premature generation retirements, improving wholesale market design, and streamlining federal permitting. Lower priority solutions focus on improving state resource planning, optimizing the existing transmission system, and improving conventional transmission expansion, which face complex political and logistical hurdles. Key actors and responsibilities are distributed: Congress addresses statutory changes like fuel assurance mandates and federal permitting reform; FERC handles wholesale market design and interconnection reforms; States reform permitting processes and engage with Regional Transmission Organizations; NERC monitors grid reliability; and Regional Transmission Organizations manage grid operations. Underlying concerns include political challenges, agency discretion regarding reliability decisions, balancing short-term costs with long-term resilience, navigating state versus federal authority, and ensuring market signals accurately reflect reliability costs and benefits. A summary table categorizes solutions by priority, key actors, importance, and implementation difficulty, encompassing expedited winterization, natural gas assurance, state permitting reforms, flexible demand, interconnection reforms, generation retirement safeguards, market design improvements, and federal permitting streamlining, alongside lower-priority initiatives for state resource planning and transmission optimization.
