The phrase "action at t" is correct and usable in written English.
It can be used in contexts related to time, particularly in discussions of events or processes occurring at a specific moment denoted by "t."
Example: "The analysis focuses on the action at t, where the variables begin to change significantly."
Alternatives: "event at time t" or "activity at time t".
When summer arrives, the action at Ted Milan, a congenial restaurant with sophisticated fare, moves to sidewalk tables and the storefront's French doors swing open to welcome the season's warm salt air.
Each policy gives a sequence of states when executed as follows:Z0→Z1→Z2... →Zt, where Z t represents the system state at time t and a t is the action at time t.
25 More precisely, π(t) summarizes all of the necessary information on the history of the process for choosing an action at time t.
In RL-based CWSN, the action a of a sensor allows to either switch from current spectrum to another new available one in the set SP, or jump from current power level to another new available one in the set PW. Here, we denote the system action at time t as (vec {a_{t}}), that is, vec{a_{t}} = (vec{a})_{t}, where (vec {a}) — a vector of actions over all agents [a1,......,a i,...].
Let x (t) and a (t) denote the state and action at decision epoch t, respectively, and consider an infinite-horizon MDP modeling where the discrete decision making process is assumed to be infinitely long.
Also, the figure shows that the vaccination function converges asymptotically to the same value as time grows (approximately V ( t ) ≈ 1, 700 ∀ t ≥ 25 days ), for any of the three considered observer gains, until the control action is removed at t f ≈ 30 days.
In this case frequency samples are taken between t = 100 ms and t = 300 ms and for the next 300 ms the necessary data processing is done and the calculations of the control algorithm are performed, whereas the control actions are executed at t = 600 ms. The whole process is repeated every 300 ms. According to [20] FMT should not exceed 100 ms, which is the value used for all simulations.
For all possible pairs of electrodes (60×59) we calculated conditional firing probabilities (CFPs) as the probability to record an action potential at electrode j at t = τ, given that one was recorded at electrode i at t = 0.
Let us consider the problem of existence and construction of solutions of the singular linear systems of ordinary differential equations with impulsive action at fixed points of time B ( t ) x ˙ = A ( t ) x + f ( t ), t ∈ [ a, b ], (1).
Because of their mode of action at the cell surface, t-toxins act only on ion channels and receptors of the cell that is expressing the t-toxin, and not on identical receptors present in neighboring cells that do not express the t-toxin.
