Hybrid quantum systems of atoms and ions

In recent years, ultracold atoms have emerged as an exceptionally controllable experimental system to investigate fundamental physics, ranging from quantum information science to simulations of condensed matter models. Here we go one step further and explore how cold atoms can be combined with other quantum systems to create new quantum hybrids with tailored properties. Coupling atomic quantum many-body states to an independently controllable single-particle gives access to a wealth of novel physics and to completely new detection and manipulation techniques. We report on recent experiments in which we have for the first time deterministically placed a single ion into an atomic Bose Einstein condensate. A trapped ion, which currently constitutes the most pristine single particle quantum system, can be observed and manipulated at the single particle level. In this single-particle/many-body composite quantum system we show sympathetic cooling of the ion and observe chemical reactions of single particles in situ.Comment: ICAP proceeding

Cold heteronuclear atom-ion collisions

We study cold heteronuclear atom ion collisions by immersing a trapped single ion into an ultracold atomic cloud. Using ultracold atoms as reaction targets, our measurement is sensitive to elastic collisions with extremely small energy transfer. The observed energy-dependent elastic atom-ion scattering rate deviates significantly from the prediction of Langevin but is in full agreement with the quantum mechanical cross section. Additionally, we characterize inelastic collisions leading to chemical reactions at the single particle level and measure the energy-dependent reaction rate constants. The reaction products are identified by in-trap mass spectrometry, revealing the branching ratio between radiative and non-radiative charge exchange processes

Acupuncture Point Localization Varies Among Acupuncturists

Background: Studies assessing the point-specific effect of acupuncture or the characteristics of acupuncture points (APs) tend to yield inconclusive results. In order to identify a possible confounding factor, we aimed to examine the variability in AP localization by means of a survey. Material and Methods: Attendees of the 14th ICMART (International Council of Medical Acupuncture and Related Techniques) congress as well as DAGfA (German Medical Society of Acupuncture) lecturers and students were asked to locate and mark the APs LI 10 and TH 5 on a research assistant's arm. Identified points were transferred into a coordinate system, and the respective bivariate distribution function was calculated. Additionally, participants filled out a questionnaire about their acupuncture education and experience, the acupuncture style and point localization techniques used most frequently, and their estimation of the size of an AP. Results: The areas of the ellipses, theoretically containing 95% of AP localizations, varied between 44.49 and 5.18 cm(2). The largest distance between 2 identified points was 8.45 cm for LI 10 and 5.3 cm for TH 5. Apart from being trained at the same school, no other factor could be identified that determined the variability in AP localization. Conclusion: Our results indicate that congruity of AP localization among experienced acupuncturists might be low. Although there are some limitations to our results, this possible bias should be taken into account when conducting acupuncture trials and interpreting results of previous acupuncture studies

Cervical Spine Involvement in Mild Traumatic Brain Injury: A Review

Background. There is a lack of scientific evidence in the literature on the involvement of the cervical spine in mTBI however, its involvement is clinically accepted. Objective. This paper reviews evidence for the involvement of the cervical spine in mTBI symptoms, the mechanisms of injury, and the efficacy of therapy for cervical spine with concussion-related symptoms. Methods. A keyword search was conducted on PubMed, ICL, SportDiscus, PEDro, CINAHL, and Cochrane Library databases for articles published since 1990. The reference lists of articles meeting the criteria (original data articles, literature reviews, and clinical guidelines) were also searched in the same databases. Results. 4,854 records were screened and 43 articles were retained. Those articles were used to describe different subjects such as mTBI’s signs and symptoms, mechanisms of injury, and treatments of the cervical spine. Conclusions. The hypothesis of cervical spine involvement in post-mTBI symptoms and in PCS (postconcussion syndrome) is supported by increasing evidence and is widely accepted clinically. For the management and treatment of mTBIs, few articles were available in the literature, and relevant studies showed interesting results about manual therapy and exercises as efficient tools for health care practitioners

Konexión Paciente: Redefining Medical Spanish Education for Spanish-Speaking Medical Students Through Patient-Based Simulation

Background and/or theoretical framework and importance to the field The disproportionate lack of Spanish-speaking (SS) physicians in U.S. regions with many SS residents emphasizes the need for increased medical Spanish education. While many schools offer Medical Spanish courses, our co-curricular, simulation-based program (Konexión Paciente/KPAX) aims to optimize learner engagement and outcomes through longitudinal integrated design, provision of feedback using validated assessment instruments, and incorporating issues of equity and inclusion. Design KPAX is a student-designed optional program that complements the formal clinical skills curriculum. Learners participate in simulated Spanish-language patient encounters adapted from institutionally-validated, English curricular material. Students are assessed on linguistic adaptability, attention to health disparities, and empathy, in addition to clinical skills proficiency. Feedback is provided based on standardized patient checklists for Spanish-language communication, general communication, and task-specific clinical skills, as well as narrative comments from physician facilitators. Outcomes Students reported greater self-efficacy and comfort in SS encounters after participating in KPAX. Participants also scored significantly higher than nonparticipant peers on general communication skills in a subsequent English curricular OSCE encounter assessing clinical content addressed in a pilot KPAX session (p Innovation's strengths and limitations KPAX provides opportunities to engage in higher-order language utilization and emphasizes patient-centeredness and linguistic/ethnocultural diversity in healthcare delivery. Further investigation is needed to address how baseline clinical skills proficiency affects acquisition of language-associated skills, as well as to define the developmental arc of Spanish-language care provision as a competency. The evolution of student performance on the assessment instruments over the course of the program is currently under investigation. Feasibility and generalizability KPAX empowers future clinician-leaders to care for the SS community. The program can be adapted for any language community at institutions with simulation capabilities, using existing curricular materials. References Dragan, A.

New low electron flux facility in the 0 to 3.5 MeV range for the study of induced signal in JUICE instruments: UVS and MAJIS measurements

We designed and built a new test facility to investigate signal induced by electrons in the 0-3.5 MeV in the JUICE UVS and MAJIS instruments. The facility uses radioisotopes sources to produce low flux of electrons (< 6000 electrons/cm².s). We present the facility, its capabilities and the results of measurements on UVS and MAJIS

Survival-Time Distribution for Inelastic Collapse

In a recent publication [PRL {\bf 81}, 1142 (1998)] it was argued that a randomly forced particle which collides inelastically with a boundary can undergo inelastic collapse and come to rest in a finite time. Here we discuss the survival probability for the inelastic collapse transition. It is found that the collapse-time distribution behaves asymptotically as a power-law in time, and that the exponent governing this decay is non-universal. An approximate calculation of the collapse-time exponent confirms this behaviour and shows how inelastic collapse can be viewed as a generalised persistence phenomenon.Comment: 4 pages, RevTe
