Natural history and pathogenesis of Takotsubo cardiomyopathy
Introduction: Takotsubo cardiomyopathy (TTC) is a transient left ventricular (LV) systolic dysfunction of uncertain pathogenesis, which occurs predominantly in ageing women. Although there is considerable uncertainty about the pathogenesis of TTC, pronounced catecholamine release and an acute …

Exploring the Effects of Rotation on Time-to-Contact Estimates in a Prediction-Motion Task
… effects of rotational motion on time-to-contact (TTC) estimates for a horizontally translating object in a prediction-motion task. Each experiment included a visible occluder that varied across trials in both position and width. Thus, across experiments the duration of occlusion and the visible …

Impact of Central Vision Loss on Eye Movements and Time-to-Contact Judgments
Background: Time-to-contact (TTC) judgments can be influenced by eye movements as well as by multisensory stimuli (i.e., presenting a stimulus that has both an auditory and visual component). To date, no study has investigated the interaction between eye movements and unimodal (visual-only) versus …

Computational Methods in Support of Chemical Risk Assessment
… of the Threshold of Toxicological Concern (TTC) approach may estimate whether the exposure levels can be considered safe. The TTC approach has recently gained increasing interest as new requirements, under different regulatory frameworks, emerge for the safety assessment of chemicals and to …

A new cyclohexyl-based chiral auxiliary: application in the total synthesis of (+)-linalool oxide
… (±)-trans-2-trityl-1- cyclohexanol ((±)-2.10 (±)-TTC)), resulting in high diastereoselectivity (dr = 97:3) in the resulting THF diols 2.51a/b. The other auxiliaries synthesised gave only moderate to no diastereoinduction. Different methods were used to resolve the racemic auxiliary (±)-TTC …

Time-to-contact statistics as a proxy for accident probabilities
… to this problem is the use of time-to-contact (TTC) statistics as a proxy for accident probabilities. Low TTC can be used as a measure of potential danger. Simulations were performed to explore whether inverse TTC can serve as a good proxy of accident probability. The resulting data was then …

Eficacia de una maltodextrina resistente a la digestión sobre el tiempo de tránsito colónico en sujetos sanos.
… de la MRD en el tiempo de tránsito colónico (TTC), la frecuencia defecatoria, el volumen de las heces, la consistencia de las heces y las variables clínicas de funcionalidad intestinal (Roma III). Material y método. Se evaluaron a 66 voluntarios adultos sanos (32 hombres y 34 mujeres) sin un …

High-pressure NMR studies of model membranes and Kramers turnover on solution
… the formation of the GelX phase. The location of TTC molecules in the bilayer vesicles has been determined by 2D NOESY experiments. In particular, $\sp{31}$P NMR experiments on multilamellar dispersions suggest that the TTC molecules are gradually expelled from the bilayers and completely excluded …

Effects of Task Clarification and an Adaptive Computer Software on Implementation of Mand Training using an iPad® as a Speech Generated Device
… as an SGD with the application Proloquo2Go™. The TTC training programs used errorless training procedures with performance-based feedback to train expert observation and coding of behavioral events (i.e. mand training sequential components) via video files. As demonstrated in a multi-component …

Internet-based Wide Area Measurement Applications in Deregulated Power Systems
… state estimation and Total Transfer Capability (TTC) calculations. As a first step for building this national transmission grid picture, WAIS and the level of information sharing of the state estimation calculations have been discussed. WAIS impacts to the TTC calculations are also covered. A new …

Driver Safety and Emissions at Different PPLT Indications
… respect to the parameter "Time to Collision (TTC)" which is directly obtained from simulator data. Vehicular emissions and fuel consumption are calculated using VT-Micro microscopic emissions model. Graphs are plotted for TTC and total emissions. Results indicate that for a day-time scenario, …

Experimental Evaluation of Innovative Thermal Energy Storage Options for a Hypersonic Non-Airbreathing Vehicle's Internal Loads
… based on PCMs, a second on thermal to chemical (TTC) energy storage, and a third on a hybrid combination of the first two. For the first, three different PCMs are tested and for the second a single endothermic chemical reaction. The hybrid PCM/TTC concept consists of a single PCM which plays the …

Essays on real life allocation problems
… We introduce two-sided top-trading-cycles (2S-TTC) mechanism that is balanced-efficient, student-strategy-proof, and respecting priority bylaws regarding dependent eligibility. Moreover, it encourages exchange, since full participation is dominant strategy for colleges. We prove 2S-TTC is the …

Measurement of Driver Preferences and Intervention Responses as Influenced by Adaptive Cruise Control Deceleration Characteristics
… motion began between 21.12s time-to-collision (TTC) and 3.97s TTC. Eighty percent of the participants paused to "cover" the brake before final motion to activate the brake. The older age group intervened (braked) later than the younger age group. Driver braking after intervention ranged from …
