Spiking neural network
A spiking neural network (SNN) is a neural network in which neurons communicate by discrete all-or-nothing pulses called spikes, often called a third generation of neural networks.
Spillover (economics)
A spillover in economics, or externality, is a cost or benefit of one agent's activity that falls on others and is not reflected in market prices.
Spillover in flexible structure control
Spillover in flexible structure control is when a controller designed for a few vibration modes of a flexible structure excites neglected higher modes, possibly causing instability.
Spillover of the Myanmar civil war (2021–present)
The spillover of the Myanmar civil war is the spread of the conflict's effects across Myanmar's borders since the 2021 military coup, chiefly refugees into Bangladesh.
Spillover of the Soviet–Afghan War in Pakistan
Spillover of the Soviet–Afghan War in Pakistan: 1979–1992 refugee influx (up to 4.5 million Afghans fled, 336 refugee villages), ISI arms channeling, Kalashnikov culture, narcotics economy, and costs to Pakistan.
Spillover of the Syrian civil war
Spillover of the Syrian civil war: the spread of Syria's 2011 conflict beyond its borders through refugee flows, economic losses, and militancy affecting Lebanon, Jordan, Türkiye, Iraq, and Europe, shifting to returns and border disputes after Assad's December 2024 fall.
Spillway
A spillway, or overflow channel, is a structure at or beside a dam that releases excess reservoir water so the dam is never overtopped and eroded.
Spillway bridge
A spillway bridge is a bridge deck carried on or across a dam spillway crest or gate structure, providing roadway access, gate-hoist support, and operator access over the flow surface.
Spillway hydraulics and safety
Spillway hydraulics and safety is the engineering analysis of whether a dam's spillway and outlet works can pass extreme floods without overtopping the dam or failing.
Spin (aerodynamics)
A spin, also called a tailspin, is an aggravated stall in which an airplane descends in a corkscrew path while rotating, with at least one wing stalled.
Spin (physics)
Spin (physics), also called quantum mechanical spin, is the intrinsic angular momentum of particles, a fixed property like mass and charge that does not come from physical rotation.
Spin (propaganda)
Spin (propaganda): the deliberate, biased interpretation of events in political communication and public relations, performed by spin doctors; the term broadened after about 1992 and was established in UK discourse by New Labour in 1997.
SPIN (Self-Play Fine-Tuning)
SPIN (Self-Play fIne-tuNing) is a post-training method for large language models, introduced at UCLA in 2024, that improves a model using its own generated responses.
Spin angular momentum of light
The spin angular momentum of light, distinct from orbital angular momentum, is the angular momentum light carries by virtue of its polarization, with each circularly polarized photon carrying ±ħ.
Spin bowling
Spin bowling is a cricket bowling method in which the bowler rotates the ball so it deviates after pitching, typically at slower speeds than fast bowlers.
Spin chain
A spin chain is a one-dimensional array of quantum spins coupled by a Hamiltonian, serving as the simplest setting for studying quantum magnetism, entanglement, and integrable systems.
