A general state-based temporal pattern recognition
Time-series and state-sequences are ubiquitous patterns in temporal logic and are widely used to present temporal data in data mining. Generally speaking, there are three known choices for the time primitive: points, intervals, points and intervals. In this thesis, a formal characterization of …

Temporal pattern recognition in multiparameter ICU data
… can pose a significant signal processing and pattern recognition challenge---often leading to false and clinically irrelevant alarms. We have developed a temporal database of several thousand ICU patient records to facilitate research in advanced monitoring systems. The MIMIC-II database …

The effects of extended practice on the control of coincident timing tasks
… by subjects to make corrections in the spatial-temporal movement pattern of coincident timing responses. Twenty-four college males and females watched a .01 sec timer and attempted to knock over a barrier at the precise moment that the sweep hand reached a "target position" (250, 500, and 1000 …

Deep Brain Stimulation to Increase Generalized Arousal in Intact Mice and a Mouse Model of Traumatic Brain Injury
… that a previously unexplored parameter of DBS, temporal pattern, can modulate its effectiveness; 3) a novel mouse model of TBI, multiple TBI, can produce motor activity and neurological deficits that last 10-14 days; 4) CT/DBS can increase generalized arousal as measured by motor activity in …

Daily patterns of oviposition mediate sexual conflict in a polygynandrous mating system
… tested whether the absence of males affected the temporal pattern of oviposition, and looked for relationships between oviposition behaviour and male/female interactions. Females oviposited under water in a manner not previously described for waterstriders. A daily rhythm in oviposition occurred …

Consumers' use of an expected future price as a reference: An investigation of the psychological and contextual antecedents
… such as the frequency of price promotions, temporal pattern of price promotions, and price trends as the factors that may lead to the use of an expected future price as a reference. Further, the current research also discusses the influence of psychological factors such as consumers’ …

Studies on the neural processing of conspecific songs in the cricket Teleogryllus oceanicus (Le Guillou)
… songs have very similar frequency spectra their temporal patterns are very different and highly complex, particularly the courtship song. Song type recognition therefore is likely to be based on neurones capable of producing an accurately coded response to the song patterns. Using extracellular …

Effect of fatigue on hamstring strain injury risk in soccer
… and lost time from training and matches. The temporal pattern of hamstring injury incidence during matches has shown almost half of all injuries to occur during the latter stages of each half, thus suggesting fatigue as an important contributing factor for injury. This thesis comprises four …

Storage and Utilization of Hexamerin Proteins in the Pitcher Plant Mosquito, Wyomyia Smithii
… female Wyeomyia smithii revealed a specific temporal pattern of utilization of hexamerin proteins for egg protein, vitellogenin, synthesis. W. smithii from North Carolina utilize majority of stored hexamerins in 30 hours after emergence with simultaneous increase in vitellogenins. Those from …

Tidal and Structural Controls on Seismic Events Near the Grounding Line at Beardmore Glacier, Antarctica
… events over this time frame had a noticeable temporal pattern that correlates well with the principally diurnal tides of Antarctica. Falling and rising tide each accounted for nearly equal occurrence of events, and most (~42%) events occurred in the last third of any tidal cycle. Event …

Influence of hydrodynamics on the larval supply to hydrothermal vents on the East Pacific Rise
… at which larval supply varies spatially and temporally, and correlation with concurrent physical observations can provide insights into larval transport mechanisms that contribute to structuring marine benthic communities. In order to facilitate field studies, this thesis first provides new …

Stimulations and modulations of chondrogenic differentiation of human embryonic stem cells
… and maturation/hypertrophy, of which distinct temporal pattern differences were observed. Further analysis suggested that BMP2 probably exerts a bipotent effect in inducing both chondrogenic and osteogenic differentiation, while TGFI?1 played a steering effect in driving chondrogenesis …

Coincidence detection in the cochlear nucleus : implications for the coding of pitch
The spatio-temporal pattern in the auditory nerve (AN), i.e. the temporal pattern of AN fiber activity across the tonotopic axis, provides cues to important features in sounds such as pitch, loudness, and spatial location. These spatio-temporal cues may be extracted by central neurons in the …

The Localization of GABA-Like Immunoreactivity in the Optic Lobe Neuropils and Optic Tracts of the Cockroach Leucophaea Maderae
… was discovered to fluctuate in a circadian pattern similar to the pattern of electrical output measured from the optic nerve in L. maderae. Considering the circadian oscillator for L. maderae has been localized to the optic lobes of the brain, the discovery of GABA-like immunoreactivity in …

Unsupervised discovery of activity primitives from multivariate sensor data
This research addresses the problem of temporal pattern discovery in real-valued, multivariate sensor data. Several algorithms were developed, and subsequent evaluation demonstrates that they can efficiently and accurately discover unknown recurring patterns in time series data taken from many …

A validation and feasibility study of the non-invasive measurement of oxygen delivery and consumption after elective major abdominal surgery.
… to meet this increase oxygen demand and the temporal pattern of this oxygen deficit appears to differ according to whether patients survive, or develop complications or not. The survival and complication profile of patients in modern practice is different from that previously described, And …

Inhibitory Control of Muscle Activity in Sleep
… drive present in REM sleep regulates the temporal pattern of phasic twitch activity that is seen across this state. I hypothesize that this progressively decreasing inhibitory input counteracts a gradually increasing excitatory input to shape the temporal distribution of muscle twitches …

Mergers and acquisitions in Australia: reasons and timing
… that merger reasons can explain the overall temporal pattern of merger waves in a systematic fashion. Finally, merger activity in Australia is closely correlated with that in UK, while there is no significant relationship between mergers patterns in Australia and USA.
