High precision cryogenic thermal conductivity standards

New apparatus allows accurate simultaneous measurement of thermal conductivity, electrical resistivity, and thermopower for technically important materials, such as new or uncommon alloys. A list of materials investigated is presented. Sources for obtaining data on these materials, as well as the source giving a description of the apparatus, are cited

Christology of 1st Thessalonians

St. Paul wrote 1st Thessalonians around the year 51 C.E. As an early letter of Paul, this document gives us some indication as to Paul\u27s belief about the person and nature of Jesus Christ, i.e. his Christology. This paper explores ten Christological themes found in 1st Thessalonians, including, One who proclaims the Word of the Lord, Suffering Servant, Comforter/Consoler, Light and Darkness, Voice to the Gentiles, Wearer of Divine Attributes, True Provider of Peace and Security, \u27Jesus: Lord, Son of God, Son from heaven,\u27 Divine Reconciliation and Restoration, and Sharer in Divine Purpose and Activity with God the Father. These ten themes are seen throughout Paul\u27s corpus and is a good starting point for understanding early Christian views of Christology through the lens of this Apostle to the Gentiles

Stressors and Supports for Baccalaureate Nursing Students Completing An Accelerated Program

This study examined stressors and resources for nursing students in an accelerated program. The research questions asked what the stressors and coping strategies are for accelerated option students. It also asked which learning strategies help or hinder accelerated option students in meeting the program objectives. The sample included students from an accelerated nursing program in an urban Midwestern university school of nursing. Participants completed a quantitative questionnaire and an interview. Findings suggested that nearly half of the students preferred the lecture format for classroom presentations. Clinical experiences were perceived as the most important component of the program. Resources included peers, family, and faculty. In understanding the stressors experienced by accelerated option students and the preferred learning strategies, the institution of nursing education may assist faculty to facilitate learning. This study forms the foundation for a second study exploring the differences in perceptions of accelerated students and the nursing faculty

Hydrogen slush density reference system

A hydrogen slush density reference system was designed for calibration of field-type instruments and/or transfer standards. The device is based on the buoyancy principle of Archimedes. The solids are weighed in a low-mass container so arranged that solids and container are buoyed by triple-point liquid hydrogen during the weighing process. Several types of hydrogen slush density transducers were developed and tested for possible use as transfer standards. The most successful transducers found were those which depend on change in dielectric constant, after which the Clausius-Mossotti function is used to relate dielectric constant and density

Quantifying lung ultrasound comets with a convolutional neural network: Initial clinical results

Lung ultrasound comets are "comet-tail" artifacts appearing in lung ultrasound images. They are particularly useful in detecting several lung pathologies and may indicate the amount of extravascular lung water. However, the comets are not always well defined and large variations in the counting results exist between observers. This study uses a convolutional neural network to quantify these lung ultrasound comets on a 4864-image clinical lung ultrasound dataset labeled by the authors. The neural network counted the number of comets correctly on 43.4% of the images and has an intraclass correlation (ICC) of 0.791 with respect to human counting on the test set. The ICC level indicates a higher correlation level than previously reported ICC between human observers. The neural network was then deployed and applied to a clinical 6272-image dataset. The correlation between the automated comet counts and the clinical parameters was examined. The comet counts correlate positively with the diastolic blood pressure (p = 0.047, r = 0.448), negatively with ejection fraction (p = 0.061, r = -0.513), and negatively with BMI (p = 0.009, r = -0.566). The neural network can be alternatively formulated as a diagnostic test for comet-positive images with 80.8% accuracy. The results could potentially be improved with a larger dataset and a refined approach to the neural networks used

Rapid detection of BRCA1/2 recurrent mutations in Chinese breast and ovarian cancer patients with multiplex SNaPshot genotyping panels.

BRCA1/2 mutations are significant risk factors for hereditary breast and ovarian cancer (HBOC), its mutation frequency in HBOC of Chinese ethnicity is around 9%, in which nearly half are recurrent mutations. In Hong Kong and China, genetic testing and counseling are not as common as in the West. To reduce the barrier of testing, a multiplex SNaPshot genotyping panel that targeted 25 Chinese BRCA1/2 mutation hotspots was developed, and its feasibility was evaluated in a local cohort of 441 breast and 155 ovarian cancer patients. For those who tested negative, they were then subjected to full-gene testing with next-generation sequencing (NGS). BRCA mutation prevalence in this cohort was 8.05% and the yield of the recurrent panel was 3.52%, identifying over 40% of the mutation carriers. Moreover, from 79 Chinese breast cancer cases recruited overseas, 2 recurrent mutations and one novel BRCA2 mutation were detected by the panel and NGS respectively. The developed genotyping panel showed to be an easy-to-perform and more affordable testing tool that can provide important contributions to improve the healthcare of Chinese women with cancer as well as family members that harbor high risk mutations for HBOC

Systemic Thrombolytic Therapy Alone and in Combination with Mechanical Revascularization in Acute Ischemic Stroke in Two Children

Thrombolytic therapy is not recommended for acute ischemic stroke (AIS) in patients under the age of 18 and published experience is limited. In this case report, we describe two children treated with systemic thrombolytic therapy. One child received additional mechanical revascularization and achieved a good clinical outcome. The differences in the fibrinolytic system and the different etiology of AIS in childhood may limit a simple extrapolation of the adult guidelines for systemic thrombolytic therapy. Acute multimodal imaging to clarify the etiology of AIS might help to select the most appropriate treatment modality
