Abstract Laryngotracheal stenosis (LTS) is a severe condition with high morbidity rate, described as the narrowing of upper airway diameter. The etiology acquired LTS dominated by prolonged tracheal intubation. diagnosis based on endoscopic examination and computed tomography scan imaging providing an exact analysis lesion, precise measurements. We report descriptive retrospective review medica...

Although the least median of squares (LMedS) method and the least trimmed squares (LTS) method are said to have a high breakdown point (50%), they can break down at unexpectedly lower percentages of outliers when those outliers are clustered. In this paper, we investigate the breakdown of LMedS and the LTS when a large percentage of clustered outliers exist in the data. We introduce the concept...

In order to manage the conceptual representation of European law we have proposed the Legal Taxonomy Syllabus (LTS) and the related methodology. In this paper we consider further legal issues that emerged during the testing and use of the LTS, and how we take them into account in the new release of the system. In particular, we consider the problem of representing interpretation of terms beside...

Some types of epileptic seizures involve both thalamus and cerebral cortex, while other types can be evoked in the cerebral cortex without thalamic participation. We investigated the possible role of low-threshold spike (LTS) cortical neurons in the genesis of these intracortical seizures. We found LTS cortical neurons in cat area 5}7 in vivo, the properties of which could be modeled based on r...

Field trials of the LTS-3 system at Keesler Air Force Base have been extended, and excellent results have been obtained with high-aptitude students, who had been excluded from earlier trials. A study of the use of the LTS for task simulation has led to the implementation of a new student response interpretation feature for the system. Design of the microfiche selector/reader breadboard for LTS-...

We characterize the statecharts step semantics of Pnueli and Shalev as a mapping from an inductively deened algebra of statecharts terms to a domain of labeled transition systems (LTSs). Statecharts equivalence = sc , i.e. LTS iso-morphism, is shown not to be a congruence and hence the step semantics is not compositional. We deene a new semantic mapping > to a domain of LTSs with a richer label...

IMPORTANCE To our knowledge, this study reports on the largest cohort of long-term survivors (LTSs) (≥10 years) following a diagnosis of pancreatic ductal adenocarcinoma (PADC) and identifies the characteristics associated with LTS. OBJECTIVE To determine patient, tumor, surgical, and sociodemographic characteristics associated with LTS. DESIGN, SETTING, AND PARTICIPANTS A nationwide retros...

Leukotrienes (LTs) are powerful inflammatory lipid mediators derived from the 5-lipoxygenase (5-LO) cascade of arachidonic acid. Recent clinical, population genetic, cell biological, and mouse studies indicate participation of the 5-LO pathway in atherogenesis and arterial wall remodeling. 5-LO is expressed by leukocytes including blood monocytes, tissue macrophages, dendritic cells, neutrophil...

Locally refined meshes severely impede the efficiency of explicit Runge-Kutta (RK) methods for the simulation of time-dependent wave phenomena. By taking smaller time-steps precisely where the smallest elements are located, local time-stepping (LTS) methods overcome the bottleneck caused by the stringent stability constraint of but a few small elements in the mesh. Starting from classical or lo...
