Variational Monte Carlo simulations using tensor-product projected states

We propose an efficient numerical method, which combines the advantages of recently developed tensor-network based methods and standard trial wave functions, to study the ground state properties of quantum many-body systems. In this approach, we apply a projector in the form of a tensor-product operator to an input wave function, such as a Jastrow-type or Hartree-Fock wave function, and optimize the tensor elements via variational Monte Carlo. The entanglement already contained in the input wave function can considerably reduce the bond dimensions compared to the regular tensor-product state representation. In particular, this allows us to also represent states that do not obey the area law of entanglement entropy. In addition, for fermionic systems, the fermion sign structure can be encoded in the input wave function. We show that the optimized states provide good approximations of the ground-state energy and correlation functions in the cases of two-dimensional bosonic and fermonic systems.Comment: 7 pages, 5 figures, published versio

Exploring the Activity of Daily Living of Sexual Activity: A Survey in Occupational Therapy Education

This study aimed to query occupational therapy educators in professional programs in the United States about the amount of time spent addressing sexual activity and the type and depth of education related to sexual activity. The study aims to inform educators about how sexual activity is taught. A cross-sectional survey research design was used with both closed- and open-ended questions. A total of 51 educators participated. An average of 3.5 hr was spent teaching sexual activity. Many of the participants were comfortable teaching sexual activity. However, some reported that sexual activity was often an overlooked topic in occupational therapy curriculum and was not emphasized as much as other activities of daily living. In addition, participants reported that the under emphasis of teaching sexuality may be due to a lack of educational background, the broadness of the topic, discomfort of the students, and a lack of information in textbooks. Most of the participants are comfortable teaching sexual activity and believe that it is an important topic in occupational therapy curriculum. However, many consider it an overlooked topic specifically with chronic conditions and sexually transmitted infections. Therefore, educating instructors on sexual activity and pedagogical methods will enhance occupational therapy curriculum

Middle and Late Latency ERP Components Discriminate between Adults, Typical Children, and Children with Sensory Processing Disorders

This study examined whether combinations of middle latency sensory evoked potential components and late components, possibly indicative of cognitive processing, can discriminate between three sample groups; 18 adults (20–55 years), 25 typical children (5–10 years) and 28 children with sensory processing disorders (SPD) (5–12 years). Electroencephalography (EEG) recordings were made while participants heard random presentations of two auditory stimuli (1 and 3 kHz) each at two intensities (50 and 70 dB). Amplitude and latency measurements were obtained for the N1, P2, N2, and P3 components from the averaged event-related potential (ERP) for each of the four auditory stimuli. Discriminant analyses revealed two functions, one which described the relationship of the components on SPD deficit continuum and one which described the relationship of these components on a developmental continuum. Together, these two functions correctly classified 90.5% of the participants as to their group membership. These results are discussed in relation to neurodevelopmental theories

Primary Care: A Service-Learning Environment for Occupational Therapy Students

This research provides evidence on occupational therapy (OT) students in primary care (PC). OT demonstrates the skills and knowledge to address chronic medical conditions in PC with entry-level education. Limited evidence of occupational therapists in PC demonstrates a need to examine OT services in this setting. In this emerging area of practice and ever-changing reimbursement models, additional evidence is needed to define the value and continuation of OT services in PC. A mixed-methods study aimed to answer the primary research question: How are OT students used in the PC setting in fieldwork or capstone experiences? A two-phase process was involved. A survey and interview enabled an in-depth exploration of how OT students are used in PC during fieldwork, experiential, and capstone experiences. The benefits identified were: providing holistic care because occupational therapists address social detriments and improvement of patient satisfaction with simple interventions. The top barriers were: limited number of occupational therapists and reimbursement for services. Common methods of student use in PC include: provide interventions, evaluate and screen for OT services, and report patient and provider satisfaction outcomes. Identification of these benefits, barriers, and methods of OT and OTA student use in PC can further advocate for the need of OT in PC while meeting ACOTE standards in education

Probing the relative contribution of the first and second responses to sensory gating indices: A meta‐analysis

Sensory gating deficit in schizophrenia patients has been well‐documented. However, a central conceptual issue, regarding whether the gating deficit results from an abnormal initial response (S1) or difficulty in attenuating the response to the repeating stimulus (S2), raise doubts about the validity and utility of the S2/S1 ratio as a measure of sensory gating. This meta‐analysis study, therefore, sought to determine the consistency and relative magnitude of the effect of the two essential components (S1 and S2) and the ratio. The results of weighted random effects meta‐analysis revealed that the overall effect sizes for the S1 amplitude, S2 amplitude, and P50 S2/S1 ratio were −0.19 (small), 0.65 (medium to large), and 0.93 (large), respectively. These results confirm that the S2/S1 ratio and the repeating (S2) stimulus differ robustly between schizophrenia patients and healthy controls in contrast to the consistent but smaller effect size for the S1 amplitude. These findings are more likely to reflect defective inhibition of repeating redundant input rather than an abnormal response to novel stimuli.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87078/1/j.1469-8986.2010.01168.x.pd

A Study of Developing a System Dynamics Model for the Learning Effectiveness Evaluation

[[abstract]]This study used the research method of system dynamics and applied the Vensim software to develop a learning effectiveness evaluation model. This study developed four cause-and-effect chains affecting learning effectiveness, including teachers’ teaching enthusiasm, family involvement, school’s implementation of scientific activities, and creative teaching method, as well as the system dynamics model based on the four cause-and-effect chains. Based on the developed system dynamic model, this study performed simulation to investigate the relationship among family involvement, learning effectiveness, teaching achievement, creative teaching method, and students’ learning interest. The results of this study verified that there are positive correlations between family involvement and students’ learning effectiveness, as well as students’ learning effectiveness and teachers’ teaching achievements. The results also indicated that the use of creative teaching method is able to increase students’ learning interest and learning achievement.[[journaltype]]國外[[incitationindex]]SCI[[ispeerreviewed]]Y[[booktype]]電子版[[countrycodes]]US

Prevention of Dental Damage and Improvement of Difficult Intubation Using a Paraglossal Technique With a Straight Miller Blade

Patients with diseased teeth, or those who are difficult to intubate, have a higher risk of dental injury during laryngoscopy. We report 3 cases of smooth endotracheal intubation using a paraglossal technique with a straight Miller blade in patients with poor dentition. Three patients with poor dentition were scheduled to undergo surgery under general anesthesia. All patients presented with extremely loose upper central incisors and had lost the other right upper teeth, while micrognathia and prominent, loose upper incisors were noted in 1 case. We elected to use a straight Miller blade using a paraglossal approach. A nasopharyngeal airway was inserted after induction of general anesthesia to facilitate mask ventilation and prevent air leakage from the mask. The Miller blade was then inserted from the right corner of the mouth, avoiding contact with the vulnerable incisors, and advanced along the groove between the tongue and tonsil. The endotracheal tube was subsequently smoothly inserted after obtaining a grade 1 Cormack and Lehane view without dental trauma in all 3 cases. Direct laryngoscopy using the paraglossal straight blade technique avoids dental damage in patients with mobile upper incisors and no right maxillary molars. It is a practical alternative method that differs from the traditional Macintosh laryngoscope in patients with a high risk of dental injury during the procedure. This technique, which provides an improved view of the larynx, might also be helpful with patients in whom intubation is difficult
