Background: Bithermal caloric irrigation, video head impulse test(vHIT), and rotational testing are commonly used to assess peripheral vestibular function, but the relative clinical utility of each test in differentiating patients with peripheral vestibulopathy is ***: To determine whether(1) the combination of two or more vestibular tests enhances diagnostic utility over a single test;(2) abnormal test results on vestibular tests correlate with one ***: Retrospective analysis of data collected from multidisciplinary vestibular clinics at two academic medical centers from 2016 to ***: 150 patients(54.10 ± 15.09 years, 88 females) were included. No individual test was significantly better at predicting the presence of peripheral vestibular damage(p > 0.05). vHIT test results improved significantly when combined with either the caloric test(p = 0.007) or rotary chair test(p = 0.039). Caloric and rotational testing had high sensitivity(74.65% and 76.06%, respectively) and specificity(83.54% and 78.48%, respectively). vHIT demonstrated excellent specificity(89.87%) but poor sensitivity(47.89%). Caloric, vHIT, and rotary chair tests results did not correlate with one another(p > 0.05).Conclusions: Vestibular function tests have comparable diagnostic utility, yet each offers unique advantages. Caloric and rotational testing may be best suited for screening peripheral damage and vHIT may function ideally as a confirmatory test.

Optimal and interactive keyframe selection for motion capture

Motion capture is increasingly used in games and movies, but often requires editing before it can be used, for many reasons. The motion may need to be adj.sted to correctly interact with virtual obj.cts or to fix problems that result from mapping the motion to a character of a different size or, beyond such technical requirements, directors can request stylistic ***, editing is laborious because of the lowlevel representation of the data. While existing motion editing methods accomplish modest changes, larger edits can require the artist to "re-animate" the motion by manually selecting a subset of the frames as *** this paper, we automatically find sets of frames to serve as keyframes for editing the motion. We formulate the problem of selecting an optimal set of keyframes as a shortest-path problem, and solve it efficiently using dynamic programming. We create a new simplified animation by interpolating the found keyframes using a naive curve fitting technique. Our algorithm can simplify motion capture to around 10% of the original number of frames while retaining most of its detail. By simplifying animation with our algorithm, we realize a new approach to motion editing and stylization founded on the timetested keyframe interface. We present results that show our algorithm outperforms both research algorithms and a leading commercial tool.

Effects of single and dual species herbivory on the behavioral responses of three thrips species to cotton seedlings

Insect Science 2017年第4期24卷 684-698页

This study investigated the olfactory responses of 3 thrips species [Frankliniella schultzei Trybom, E occidentalis Pergrande and Thrips tabaci Lindeman （Thysanoptera： Thripidae）] to cotton seedlings [Gossypium hirsutum L. （Malvales： Malvaceae）] simulta- neously damaged by different combinations of herbivores. Cotton seedlings were damaged by foliar feeding Tetranychus urticae Koch （Trombidiforms： Tetranychidae）, Helicoverpa armigera Hibner （Lepidoptera： Noctuidae）, Aphis＇ gossypii Glover （Hemiptera： Aphidi- dae） or root feeding Tenebrio molitor L. （Coleoptera： Tenebrionidae）. Thrips responses to plants simultaneously damaged by 2 species of herbivore were additive and equivalent to the sum of the responses of thrips to plants damaged by single herbivore species feeding alone. For example, E occidentalis was attracted to T. urticae damaged plants but more attracted to undamaged plants than to plants damaged by H. armigera. Plants simultane- ously damaged by low densities of T. urticae and H. armigera repelled E occidentalis but as T. urticae density increased relative to H. armigera density, E occidentalis attraction to coinfested plants increased proportionally. Thrips tabaci did not discriminate between un- damaged plants and plants damaged by H. armigera but were attracted to plants damaged by T. urticae alone or simultaneously damaged by T. urticae and H. armigera. Olfactometer assays showed that simultaneous feeding by 2 herbivores on a plant can affect predator- prey interactions. Attraction of F. occidentalis to plants damaged by its T. urticae prey was reduced when the plant was simultaneously damaged by H. armigera, T. molitor, or A. gossypii and F. schultzei was more attracted to plants simultaneously damaged by T. urticae and H. armigera than to plants damaged by T. urticae alone. We conclude that plant responses to feeding by I species of herbivore are affected by responses to feeding by other herbivores. These plant-mediated interactions between herbivo

Effect of the postfeeding interval on olfactory responses of thrips to herbivore-induced cotton plants

引用

Insect Science 2016年第6期23卷 881-892页

作者： Rehan Silva Gimme H. Walter lewis j. Wilson Michael j. Furlong School of Biological Sciences University of Queensland St. Lucia Queensland 4072 Cotton Research Unit CSIRO Agriculture Flagship Narrabri NSW 2390 Austrafia

We investigated the responses of 3 thrips species, Frankliniella schultzei Tryborn, E occidentalis Pergrande, and Thrips tabaci Lindeman （Thysanoptera： Thripidae） to herbivore-damaged and undamaged cotton seedlings （Gossypium hirsutum L. [Malvales： Malvaceae]） at a range of time intervals following damage by adult Tetranychus urticae （Koch）, adult T. ludeni （Zacher）（Acari： Tetranychidae） or Helicoverpa armigera （Hubner）（Lepidoptera： Noctuidae） larvae in olfactometer assays. The intensity/frequency of the response of thrips to herbivore-induced plants decreased with time and ultimately disappeared in all cases; however, the rate at which the response declined was related to the herbivore species that inflicted the damage. All 3 species of thrips were attracted to plants damaged by T. urticae for longer than they were to plants damaged by T. ludeni. The duration for which damaged plants remained attractive was also affected by the degree of damage inflicted on cotton seedlings. For example, E schultzei was attracted to plants damaged by a higher density of two-spotted spider mites （100/plant） for much longer than to plants damaged by a lower density of these mites （50/plant）. The results reinforce previous studies that demonstrate that arrangement of variables influences the responses of thrips to their herbivore-induced cotton host plants. Results also show that these responses are variable in time following herbivore damage to cotton plants, which further demonstrates how difficult it is to generalize about the functional significance of these interactions.

A Putative Nuclear CLE-Like （CLEL） Peptide Precursor Regulates Root Growth in Arabidopsis

Molecular Plant 2012年第4期5卷 955-957页

作者： Ling Meng Bob B. Buchanan lewis j. Feldman Sheng Luan Department of Plant and Microbial Biology University of California Berkeley CA USA

Dear Editor, It is well established that local intercellular signaling net- works control cell identity and activity. Secreted peptides have been found to play a central role in this capacity in plants （Matsubayashi and Sakagami, 2006; Meng et al., 2010; Meng, 2012）. CLEL, which is the term for CLE （CLV3/ESR-related）-Iike peptides （also previously named as RGFs for root growth fac- tors by Matsuzaki et al. （2010））, regulate root growth pattern and lateral root development in Arabidopsis （Matsuzaki et al., 2010; Meng et al., 2012）. CLEL peptide precursors contain an N-terminal signal peptide （hydrophobic patch）, a diverse vari- able region,
