Linear and Volumetric Mandibular Asymmetries in Adult Patients With Different Skeletal Classes and Vertical Patterns: A Cone-Beam Computed Tomography…
2018
AbstractThis study aimed to quantify the height of the mandibular condyle and ramus, condylar volume, and the asymmetry index in adult patients of different sex, skeletal class and vertical pattern using Cone-Beam Computed Tomography (CBCT), and to determine whether there were differences between these groups. The study used CBCT scans of 159 patients with a mean age of 32.32 ± 8.31 years. InVivoDental® software was used to perform both linear (condylar, ramal, and total height) and condylar volume measurements. Linear and volumetric asymmetries were calculated. There were not significant differences between right and left sides. The mean value obtained for condyle height was 7.27 mm, ramus…
Vestibular evoked myogenic potential findings in multiple sclerosis.
2013
Abstract Introduction Multiple sclerosis is an inflammatory disease involving the occurrence of demyelinating, chronic neurodegenerative lesions in the central nervous system. We studied vestibular evoked myogenic potentials (VEMPs) in this pathology, to allow us to evaluate the saccule, inferior vestibular nerve and vestibular-spinal pathway non-invasively. Methods There were 23 patients diagnosed with multiple sclerosis who underwent VEMP recordings, comparing our results with a control group consisting of 35 healthy subjects. We registered p13 and n23 wave latencies, interaural amplitude difference and asymmetry ratio between both ears. Subjects also underwent an otoscopy and audiometric…
Gait reveals bilateral adaptation of motor control in patients with chronic unilateral stroke.
2008
Background and aims: Functional brain imaging has shown that bilateral brain reorganization may occur after unilateral cerebral damage. The present study searched for evidence of bilateral motor control changes in gait in patients with chronic unilateral stroke. Methods: Gait variables (temporal and spatial parameters, footprint peak times (FPPT) and footfall times (FFT)) were recorded in 48 patients with chronic unilateral stroke at their preferred speed, and in 10 healthy volunteers walking from very slowly to very fast on a pressure sensor walkway. The data were divided into 4 groups according to gait velocity. The functional outcome of stroke was measured by the Barthel Index. Results: …
Complete Measurement of the Λ Electromagnetic Form Factors.
2019
The exclusive process e+e−→ΛΛ¯, with Λ→pπ− and Λ¯→p¯π+, has been studied at s=2.396 GeV for measurement of the timelike Λ electric and magnetic form factors, GE and GM. A data sample, corresponding to an integrated luminosity of 66.9 pb−1, was collected with the BESIII detector for this purpose. A multidimensional analysis with a complete decomposition of the spin structure of the reaction enables a determination of the modulus of the ratio R=|GE/GM| and, for the first time for any baryon, the relative phase ΔΦ=ΦE−ΦM. The resulting values are R=0.96±0.14(stat)±0.02(syst) and ΔΦ=37°±12°(stat)±6°(syst), respectively. These are obtained using the recently established and most precise value of …
Theory of Neutrinos: A White Paper
2005
During 2004, four divisions of the American Physical Society commissioned a study of neutrino physics to take stock of where the field is at the moment and where it is going in the near and far future. Several working groups looked at various aspects of this vast field. The summary was published as a main report entitled ``The Neutrino Matrix'' accompanied by short 50 page versions of the report of each working group. Theoretical research in this field has been quite extensive and touches many areas and the short 50 page report provided only a brief summary and overview of few of the important points. The theory discussion group felt that it may be of value to the community to publish the e…
Two-parton contribution to the heavy-quark forward–backward asymmetry in NNLO QCD
2006
Forward-backward asymmetries, $A_{FB}^Q$, are important observables for the determination of the neutral-current couplings of heavy quarks in inclusive heavy quark production, $e^+ e^- \to \gamma^*, Z^* \to Q +X$. In view of the measurement perspectives on $A_{FB}^Q$ at a future linear collider, precise predictions of $A_{FB}^Q$ are required for massive quarks. We compute the contribution of the $Q \bar Q$ final state to $A_{FB}^Q$ to order $\as^2$ in the QCD coupling. We provide general formulae, and we show that this contribution to $A_{FB}^Q$ is infrared-finite. We evaluate these two-parton contributions for $b$ and $c$ quarks on and near the $Z$ resonance, and for $t$ quarks above thres…
The Factor Structure of Medical Tourist Satisfaction: Exploring Key Drivers of Choice, Delight, and Frustration
2021
The current study intends to contribute to a better understanding of the medical tourism experience. In particular, this study uses data from a survey-based study conducted on a sample of 1,209 medical tourists in Croatia. On the one hand, this study aims to explore and shed light on the decision-making process of medical tourists, and, on the other hand, to reveal which elements of both the medical institution and the destination where it is located, have largest potentials to drive medical tourist delight and/or frustration, in accordance with the three-factor theory of customer satisfaction.
Exploring relationships between customer-based brand equity and its drivers and consequences in the hotel context. An impact-asymmetry assessment
2016
The development of customer-based brand equity plays a critical role in tourism. This paper attempts to study which variables contribute to brand equity creation and to examine whether brand loyalty can be considered as a consequence of brand equity in the hotel context. In addition, it seeks to provide a more detailed insights into possible asymmetric effects among customer-based brand equity and its drivers and consequences. Four constructs are found to influence significantly brand equity: two perceptual (image and perceived quality) and two relational variables (trust and affective commitment). Additionally, both behavioural and attitudinal components of loyalty are confirmed as brand e…
Polityczność feminatywów
2022
The article takes a diachronic look at feminatives in the Polish language from the sixteenth century to the present day. The authors recall the history of female forms in the language. Referring to pre-war journalism, discussions in the journal Poradnik Językowy [The Linguistic Guide] and the propaganda lexis of communist Poland, they prove that female forms are not foreign to the Polish language. They create a comprehensive list of reasons why feminatives have disappeared from Polish, taking account of both intra-linguistic and extra-linguistic factors. The authors refer to examples from contemporary media and public discourse to show gender asymmetry in the language and the mechanisms of …
Asymmetries of Knowledge and Epistemic Change in Social Gaming Interaction
2014
While a growing number of studies investigate the role of knowledge and interactional management of knowledge asymmetries in conversation analysis, the epistemic organization of multilingual and second language interactions is still largely unexplored. This article addresses this issue by investigating how knowledge asymmetries and changing positions with regard to knowledge impact social interaction in multilingual gaming activities. Drawing on a collection of video recordings of social gaming sessions collected over a two year period and involving the same two participants, we examine how the participants orient to knowledge and deal with knowledge asymmetries while solving game-related p…
