This paper introduces the newly developed principal component powered two-dimensional (2D) correlation spectroscopy (PC 2D-COS) as an alternative approach to 2D correlation spectroscopy taking advantage of a dimensionality reduction by principal component analysis. It is shown that PC 2D-COS is equivalent to traditional 2D correlation analysis while providing a significant advantage in terms of computational complexity and memory consumption. These features allow for an easy calculation of 2D correlation spectra even for data sets with very high spectral resolution or a parallel analysis of multiple data sets of 2D correlation spectra. Along with this reduction in complexity, PC 2D-COS offers a significant noise rejection property by limiting the set of principal components used for the 2D correlation calculation. As an example for the application of truncated PC 2D-COS a temperature-dependent Raman spectroscopic data set of a fullerene-anthracene adduct is examined. It is demonstrated that a large reduction in computational cost is possible without loss of relevant information, even for complex real world data sets.Purpose The purpose of this project was to explore the association between the perception of motion during caloric testing and two tasks associated with central vestibular processing postural stability and visuospatial memory. Method This was a prospective study of 25 patients who were found to have nonvestibular etiologies of their symptoms and normal vestibular function test results and who underwent caloric testing with a mean maximum slow phase eye velocity for each irrigation of 15° or greater. Following each caloric irrigation, patients were asked whether they had any sensation of movement. Patients were grouped based on the presence or absence of motion during the caloric exam (motion perception vs. absent perception). Postural stability was assessed using computerized dynamic posturography, and visuospatial memory was assessed using a memory match card game application. Results There were no significant differences between groups on any measures of peripheral vestibular function. However, the Absent Perception Group showed greater postural instability during Condition 5 of posturography and performed significantly worse on a task of visuospatial working memory. selleck Both age and absence of motion perception predicted abnormal performance on measures of postural stability and visuospatial working memory. Conclusions There appears to be clinical implications to a lack of motion perception during the caloric exam in patients with an otherwise normal peripheral vestibular system. Based on the current findings, we are unable to determine whether differences in postural stability and visuospatial memory were due to age or a central vestibular processing deficit.Purpose The purpose of this study was to investigate whether preschool-age children who stutter (CWS) were more likely to exhibit a temperamental trait of behavioral inhibition (BI), a correlate of shyness, than children who do not stutter (CWNS) and whether this temperamental trait affected preschool-age children's speech fluency and language complexity during a conversation with an unfamiliar adult. Method Sixty-eight preschool-age children (31 CWS, 37 CWNS) participated. The degree of BI was assessed by measuring the latency to their sixth spontaneous comment and the number of all spontaneous comments during a conversation with an unfamiliar examiner (following Kagan et al.'s [1987] methodology). Parent report of shyness from the Children's Behavior Questionnaire served as an indirect measure of BI. Children's language complexity was assessed by measuring their mean length of utterance and the number of words spoken. For CWS, the frequency of stuttering and the negative impact of stuttering were also assessed. Results First, we found no between-group differences in the degree of BI across the behavioral observation measures. However, CWS were rated shyer by parents than CWNS. Second, for CWS only, higher BI was associated with less complex utterances and fewer words spoken. Third, for CWS, higher BI was associated with fewer stuttered disfluencies produced. Conclusions This study provides empirical evidence that BI to the unfamiliar may have salience for childhood stuttering as it affected the quantity and quality of language spoken with an unfamiliar adult. Clinical implications of high BI for the assessment and treatment of preschool-age stuttering are discussed.OBJECTIVES To evaluate the presence of dehiscences and changes in alveolar bone height and width in the area of the mandibular central incisors pre- and post-orthodontic treatment. MATERIALS AND METHODS In 60 skeletal Class II patients, cone-beam computed tomographic (CBCT) images were obtained and the patients were divided into four groups based on the presence of dehiscences at pre- and post-orthodontic treatment. The alveolar bone height and width were measured on CBCT in cross section along the long axis of the teeth. Lateral cephalograms were analyzed. RESULTS The changes in L1-NB and IMPA appeared to be correlated with vertical bone loss and dehiscence. Alveolar bone height appeared to follow a segmented relationship with these two variables, with changes below a threshold (L1-NB = 0.71 mm, IMPA = 3.02°) having relatively minimal or no effect on bone loss but with changes beyond the threshold correlated with extensive bone loss. Similarly, increases in L1-NB or IMPA correlated with decreases in alveolar bone width (L1-NB -0.25 mm/mm, IMPA -0.07 mm/°) and increased the probability of developing dehiscences, with an estimated 50% probability of vertical bone loss at a L1-NB change of 2.00 mm or, equivalently, an IMPA change of 8.02° was estimated. CONCLUSIONS When treating skeletal Class II patients, the limits of incisor proclination/protraction are less than previously thought. To prevent undesired periodontal outcomes, careful three-dimensional diagnosis is advisable. Furthermore, when excessive protrusion and/or proclination is planned, additional treatment modalities, including orthognathic surgery, tooth extraction, and corticotomy with bone graft, should be considered.
