27 Mar 2003TL;DR: In this article, a quality-of-service controller and related method for a data storage system are prioritized by computing a target deadline for a request based on a monitored arrival time of the request and a target latency for its workload.
Abstract: A quality-of-service controller and related method for a data storage system. Requests for each of a plurality of storage system workloads are prioritized. The requests are selectively forwarded to a storage device queue according to their priorities so as to maintain the device queue at a target queue depth. The target queue depth is adjusted response to a latency value for the requests wherein the latency value is computed based on a difference between an arrival time and a completion time of the requests for each workload. Prioritizing the requests may be accomplished by computing a target deadline for a request based on a monitored arrival time of the request and a target latency for its workload. To reduce latencies, the target queue depth may be reduced when the target latency for a workload is less than its computed latency value. To increase throughput, the target queue depth may be increased when the target latency for each workload is greater than each computed latency value.

TL;DR: An unexpected finding was that the initial discharge at threshold is a low probability event that can be evoked, except for a short initial time period, by any stimulus cycle throughout the tone duration.
Abstract: 1. Latency behavior of neurons in the cochlear nuclear complex was studied in 45 barbiturate-anesthetized cats. Stimuli were tonal bursts usually 50-500 ms in duration. 2. Latency of the initial discharge is a systematic function of the frequency and intensity of the tone for a large class of neurons which are termed latency precedence cells. Most cells in the anteroventral cochlear nucleus and many neurons in the anterior division of the posteroventral nucleus belong to this class. Unless otherwise stated, all findings pertain to this cell group. 3. There is usually a correspondence between the discharge rate of a given neuron and the latency of the initial discharge, the higher the discharge rate the shorter the latency. Hence, for any intensity level evoking less than saturation discharge rate, initial discharge latency tends to be ‘shortest for best-frequency stimuli and lengthens systematically as the stimulating frequency departs in either direction from best frequency. However, for some cells, intense stimuli above best frequency evoke initial discharges at latencies which are similar to those produced by best-frequency stimuli. 4. An unexpected finding was that the initial discharge at threshold is a low probability event that can be evoked, except for a short initial time period, by any stimulus cycle throughout the tone duration. Hence, tone duration is a parameter in determining the threshold. Within limits, the longer the

TL;DR: In this paper, a plurality of reference nodes that are attached to the network are correlated with geographic location, and communication latency between the reference nodes are used to approximate the location of a target node once the communication latency from one of the reference node to the target node is determined.

TL;DR: Given the strong circumstantial evidence supporting a natural history of HPV infection which includes a immunologically controlled latent state, the longer term implications of HPV latency on a highly infected and aging population may warrant a more serious evaluation.
Abstract: At present, there is no consensus in the scientific community regarding the ability for human papillomavirus (HPV) infections to establish latency. Based on animal studies, a model of papillomavirus latency has been proposed in which papillomaviruses can be retained in the basal epithelial stem cell pool as latent infections and periodically induced to reactivate when the stem cell divides and one daughter cell is committed to terminal differentiation and induction of the viral life cycle. Tissue resident memory T-cells are hypothesized to control these periodic reactivation episodes and thus limit their duration. In this paper, evidence from human studies consistent with this model of papillomavirus latency is reviewed. Given the strong circumstantial evidence supporting a natural history of HPV infection which includes a immunologically controlled latent state, the longer term implications of HPV latency on a highly infected and aging population may warrant a more serious evaluation.
