Psychosexual Stages of Personality: Latency
0 Views •
2025
Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage. The latency period is not considered...

2019
This protocol provides a method to establish humanized mice (hu-NSG) via intrahepatic injection of human hematopoietic stem cells into radiation-conditioned neonatal NSG mice. The hu-NSG mouse is susceptible to HIV infection and combinatorial antiretroviral therapy (cART) and serves as a suitable pathophysiological model for HIV replication and latency investigations.
FAQs
Model latency often reflects several sequential or interacting delays rather than model computation alone. Input preprocessing can postpone execution, data transfer can add communication time, and output generation can extend completion after computation. Examining these stages separately helps engineers determine whether responsiveness is limited by the model, surrounding software, or system architecture.
Model complexity, hardware, workload, and system architecture can all shift model latency. A more complex model may require more computation, while hardware capability influences how quickly that computation proceeds. Changes in workload or architecture can add pressure elsewhere in the processing path, so latency should be evaluated under representative operating conditions.
Profiling breaks the overall delay into meaningful contributors, including preprocessing, data transfer, computation, and output generation. This makes optimization more targeted: engineers can determine whether an algorithmic change, hardware acceleration, memory improvement, or deployment adjustment addresses the dominant source. Without this breakdown, reducing one stage may leave total responsiveness largely unchanged.
Engineers can begin by profiling the complete processing path, then identify the stage contributing most to delay. They may apply an optimized algorithm, use hardware acceleration, improve memory efficiency, or select a more suitable deployment design. Reprofiling after each change shows whether the intervention improves overall responsiveness rather than merely shifting delay to another stage.
Deployment design influences latency because the model operates within a larger system that includes data handling, computation, and output stages. Engineers therefore choose architectures that address the system's workload and hardware conditions, rather than optimizing the model in isolation. This systems-level view is especially important when delays arise outside the computational step.
Low model latency is particularly important in robotics, autonomous systems, interactive software, and industrial control. In these settings, delayed outputs can reduce system performance, reliability, or user experience. Engineering teams use latency analysis and optimization to support more responsive operation, especially when the system must react promptly to changing inputs or conditions.
