PÂTÉ: A Corpus of Temporal Expressions for the In-car Voice Assistant Domain
<p><strong>PÂTÉ: A Corpus of Temporal Expressions for the In-car Voice Assistant Domain</strong></p> <p>We present <strong>PÂTÉ: A Corpus of Temporal Expressions for the In-car Voice Assistant Domain</strong>. PÂTÉ is a dataset of natural-language commands containing temporal expressions for an AI voice assistant.</p> <p>The dataset is presented in:</p> <p>Zarcone, Alessandra and Alam, Touhidul and Kolagar, Zahra (2020).

Ethylene glycol assisted 3D floral evolution of BiFeO3-based nanostructures with effective magneto-electric response
<p>Controlled growth of nanostructures plays a vital role in tuning the physical and chemical properties of functional materials for advanced energy and memory storage devices. Herein, we synthesized hierarchical micro-sized flowers, built by the self-assembly of highly crystalline, 2-dimensional nanoplates of Co and Ni doped BiFeO<sub>3</sub>, using a simple ethylene glycol mediated solvothermal method. Pure BiFeO<sub>3</sub> attained scattered one-dimensional nanorods-type morphology having diameter nearly 60 nm. Co-doping of Co and Ni at Fe-site in BiFeO<sub>3</sub> does not destabilize the morphology; rather it generates 3-dimensinal floral patterns of self-assembled nanoplates. Unsaturated polarization loops obtained for BiFeO<sub>3</sub> confirmed the leakage behavior of these rhombohedrally distorted cubic perovskites. These loops were then utilized to determine the energy density of the BiFeO<sub>3</sub> perovskites. Enhanced ferromagnetic behavior with high coercivity and remanence was observed for these nanoplates. A detailed discussion about the origin of ferromagnetic behavior based on Goodenough-Kanamori's rule is also a part of this paper. Impedance spectroscopy revealed a true Warburg capacitive behavior of the synthesized nanoplates. High magneto-electric coefficient of 27 mV/cm.Oe at a bias field of -0.2 Oe was observed which confirmed the existence of magneto-electric coupling in these nanoplates.</p>

Synthesis of novel mesoporous silicate molecular sieves by Aerosol-assisted method for loading and release of drug
<p>The novel mesoporous silicate molecular sieves were synthesized with polyether F127 as the template by aerosol-assisted method for loading and release of ibuprofen. The synthesized samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and N<sub>2</sub> adsorption-desorption isotherms. The drug ibuprofen was applied as a model drug to investigate the drug release behavior by UV spectrophotometry measurements. The investigation results demonstrate that mesoporous silicate molecular sieves by aerosol-assisted method are spherical with the core-shell structure. As the drug carrier, it has good structural stability and can achieve drug controlled release which is expected. Therefore, the aerosol-assisted synthesis method provides a new idea for the synthesis of sustained-release drug carriers.</p>
Attitudes, Stressors and Work Outcomes related to the COVID-19 Pandemic among Dental Assistants in Germany: A cross-sectional Study
<p>This dataset stems from across-sectional study conducted early April 2020 among n=1481 dental assistants from entire Germany during the peak of the SARS-CoV-2 pandemic. The study questionnaire was distributed online with help of the Association of Medical Professionals on their social media channels. The collected data provides insights into major stressors among dental assistants at the peak of the pandemic in Germany and allows for analysis of possible determinants of major stressors via logistic regression analysis. No funding was obtained for this study. </p> <p> </p> <p><strong>Dataset information: </strong></p> <p>File type: SPSS file (.sav)</p> <p>Study type: Cross-sectional study</p> <p>Population: Dental assistants in Germany</p> <p>Study period: April 7th-April 14th, 2020</p> <p>Number of participants: 1481</p> <p>Research question: Investigation of attitudes, stressors and work outcomes related to the COVID-19 pandemic among dental assistants in Germany</p> <p>Missing values: None </p> <p>Original variables: v_982, v_1, v_2, v_3, v_5, v_6, v_7, v_10, v_11, v_13, v_14, v_21, v_22, v_23, v_24, v_26, v_27, v_28, v_29, v_31, v_32, v_33, v_40, v_41, v_42, v_43, v_46, v_47, v_48, v_49, v_52, v_57, Beruf_ZFA</p> <p>Modification of variables: All other variables were calculated from the original variables bei either rescaling or dichotomization. </p> <p>Dichotomization of attitudes, stressors and work outcomes: <br> Answer options "Strongly disagree" and "Disagree" were labelled as "no"<br> Answer options "Agree" and "Strongly Agree" were labelled as "yes"</p> <p>Dichotomization of self-rated health:<br> Answer options "Very bad", "Bad" and "Moderate" were labelled as "Bad".<br> Answer options "Good" and "Very good" were labelled as "Good". </p> <p>Rescaling of the variable "Where do you currently work?":<br> Participants who stated "dental practice" as their place of work were labelled as working in a "dental practice".

The effect of an end-effector type of robot-assisted gait training on patients with Guillain-Barré syndrome
<p>Background: Guillain-Barre syndrome (GBS) is a peripheral nerve injury caused by a post-infectious immune response. Although the prognosis of GBS is relatively good, some patients have severe impairments such as walking disabilities. Robot-assisted gait training (RAGT) is used to improve gait function in various neurologic disorders; however, no studies have reported its effectiveness in GBS patients. We aimed to evaluate the effect of gait training using an end-effector type robotic device on GBS patients.</p> <p>Methods: This was a retrospective study of patients diagnosed with GBS who received RAGT using Morning Walk® at the inpatient department. The main outcome measures evaluated before and after RAGT were: Medical Research Council scale, Functional Ambulation Categories, Modified Barthel Index score, Rivermead Mobility Index, and 2-minute walk test.</p> <p>Results: In total, 15 patients underwent RAGT 24 times. The mean age was 55.7 (±15.3) years and the average time from onset was 3.9 (±3.6) months. When compared to the baseline, all outcome measures associated with gait function were improved after RAGT.</p> <p>Conclusions: RAGT can improve walking ability in GBS patients. RAGT can be considered as one of the gait training tools to recover gait function in GBS patients.</p>
