Experimental Measurement of Diffusion Coefficient of Polyimide Film for Capacitive Humidity Sensors.

Polyimide (PI) film is widely used as the key component of the capacitive humidity sensor, whose diffusion coefficient has a significant impact on the sensor's dynamic characteristics, but is rarely discussed. This paper provides a test method and processes for effective diffusion coefficients of water molecules in self-synthesis PI films. The films were formed by four ingredients (PMDA-ODA, BPDA-ODA and BPDA-BAPP, PMDA-BAPP) with PI acid concentrations of 23%, 20%, 17% and 15%, and tested in temperatures of 20 °C, 35 °C and 50 °C, respectively.

Tuning the dielectric response by co-crystallisation of sumanene and its fluorinated derivative.

A series of co-crystals of 1,1-difluorosumanene (F2-Sum) and sumanene (Sum) were obtained. The co-crystallization successfully tuned their structural and physical properties, especially the dielectric response, without any chemical modifications. X-ray analyses and theoretical calculations revealed the reduction of intermolecular interaction energy due to the presence of F2-Sum.

Ferroelectric columnar assemblies from the bowl-to-bowl inversion of aromatic cores.

Organic ferroelectrics, in which the constituent molecules retain remanent polarization, represent an important topic in condensed-matter science, and their attractive properties, which include lightness, flexibility, and non-toxicity, are of potential use in state-of-the-art ferroelectric devices. However, the mechanisms for the generation of ferroelectricity in such organic compounds remain limited to a few representative concepts, which has hitherto severely hampered progress in this area. Here, we demonstrate that a bowl-to-bowl inversion of a relatively small organic molecule with a bowl-shaped π-aromatic core generates ferroelectric dipole relaxation.

Mixed Columnar Assembly of Ferroelectric and Antiferroelectric Benzene Derivatives Bearing Multiple -CONHCH Chains.

The discotic hexagonal columnar (Col) liquid crystalline phases of simple benzene derivatives bearing -CONHCH chains at the 1-, 3-, and 5-positions () and 1-, 2-, 4-, and 5-positions () display ferroelectricity and antiferroelectricity, respectively. The phase transition behavior, molecular assembly structures, dielectric response, and ferroelectric properties of their mixed crystals [()()] were evaluated to clarify the nanoscaling effect on the collective inversion of the one-dimensional (1D) N-H···O═ hydrogen bonding interaction observed in the () chain. A small quantity of doped into ( ≤ 0.

Impact of NPS MedicineWise general practitioner education programs and Choosing Wisely Australia recommendations on prescribing of proton pump inhibitors in Australia.

Background: This study evaluated the impact of multifaceted NPS MedicineWise programs that targeted all general practitioners (GPs) in Australia in 2009 and 2015 with the aim of reducing unnecessary prescribing of proton pump inhibitors (PPIs) and encouraged stepping down to a lower strength PPI or to discontinue treatment. The 2015 intervention coincided with the release of Choosing Wisely Australia recommendations from the Royal Australian College of General Practitioners (RACGP).

Methods: Outcome measures included monthly dispensing rates of different strength PPIs prescribed by GPs to concessional patients in Australia.

The genus (Catathelasmataceae, Basidiomycota) in China.

Two new species, and , are described on the basis of morphological characters, phylogenetic evidence, host preferences and geographic distributions. A taxonomic key to the known species in China is also provided to facilitate identification. Based on samples from temperate Asia, Europe and North America, the phylogeny of was reconstructed using the internal transcribed spacer (ITS) region, the large subunit (LSU) of the ribosomal DNA and the translation elongation factor 1-α (TEF1).

A national intervention to reduce imaging for low back pain by general practitioners: a retrospective economic program evaluation using Medicare Benefits Schedule data.

Background: The overuse of diagnostic imaging for low back pain (LBP) in Australia results in unnecessary cost to the health system and, for patients, avoidable exposure to radiation. The 2013 NPS MedicineWise LBP program aimed to reduce unnecessary diagnostic imaging for non-specific acute LBP in the Australian primary care setting. The LBP program delivered referral pattern feedback, a decision support tool and patient information to 19,997 (60%) of registered Australian general practitioners (GPs).

Relationship between antimicrobial-resistance programs and antibiotic dispensing for upper respiratory tract infection: An analysis of Australian data between 2004 and 2015.

Objective NPS MedicineWise aims to ensure that medicines are prescribed and used in a manner consistent with current evidence-based best practice. A series of nationwide educational and advertising interventions for general practitioners and consumers were implemented in Australia between 2009 and 2015 with the aim of reducing antibiotic prescriptions for upper respiratory tract infections (URTIs). The work described in this paper quantifies the change in antibiotic dispensing following these interventions.

[Measurements and analyses of full length weight bearing X ray radiographs of bilateral lower extremities in patients with knee osteoarthritis].

Objective: To reveal the characteristics of anatomical and mechanical axes in lower extremities by analyzing full length weight bearing X ray radiographsin patients with knee osteoarthritis(OA).

Methods: From June 2015 to May 2016, the lower extremity CTA was performed for 20 patients with vascular diseases, and these patients without OA were assigned to the normal group. There were 7 males and 13 females, ranging in age from 24 to 72 years old with an average age of 63.

Inferring HIV incidence from case surveillance with CD4+ cell counts.

Background: In some countries, HIV surveillance is based on case-reporting of newly diagnosed infections. We present a new back-projection method for estimating HIV-incidence trends using individuals' CD4 cell counts at diagnosis.

Methods: On the basis of a review of CD4 cell count distributions among HIV-uninfected people, CD4 cell count following primary infection, and rates of CD4 cell count decline over time among people with HIV, we simulate the expected distribution in time between infection and diagnosis.

Relative risk of renal disease among people living with HIV: a systematic review and meta-analysis.

Background: Antiretroviral therapy (ART) has substantially decreased mortality and HIV-related morbidity. However, other morbidities appear to be more common among PLHIV than in the general population. This study aimed to estimate the relative risk of renal disease among people living with HIV (PLHIV) compared to the HIV-uninfected population.

[Preimplantation genetic diagnosis for a patient with Robertsonian translocation].

Objective: To investigate the feasibility and risk of preimplantation genetic diagnosis (PGD) for screening normal offspring of Robertsonian translocation carriers.

Methods: This case was clinically diagnosed as primary infertility for 6 years; the husband was found to have chromosome der (13;14) (q10;q10) and oligozoospermia. For the solution of the couple's problem, controlled ovarian hyperstimulation (COH) and intracytoplasmic sperm injection (ICSI) were performed to obtain embryos.
