“…Mittal et al (2015) observed statistically significant infrared excess luminosity for HD 104231 A in Spitzer 10µm (S/N = 6.85) and 20µm (S/N = 12.82) bands, corresponding to silicate emission line features. Tobal (2000) reported astrometry for a companion at 7.7 observed in 1997, labeled HD 104231 B in the Washington Double Star catalog (WDS), however no further observations of this companion are reported, nor is there a corresponding source in Gaia EDR3. We conclude this is spurious and adopt the 4.5 companion (labeled HD 104231 C in WDS) to be HD 104231 B.…”

Improving direct detection capability close to the star through improved star-subtraction and post-processing techniques is vital for discovering new low-mass companions and characterizing known ones at longer wavelengths. We present results of 17 binary star systems observed with the Magellan Adaptive Optics system (MagAO) and the Clio infrared camera on the Magellan Clay Telescope using Binary Differential Imaging (BDI). BDI is an application of Reference Differential Imaging (RDI) and Angular Differential Imaging (ADI) applied to wide binary star systems (2″ <Δρ < 10″) within the isoplanatic patch in the infrared. Each star serves as the point-spread-function (PSF) reference for the other, and we performed PSF estimation and subtraction using Principal Component Analysis. We report contrast and mass limits for the 35 stars in our initial survey using BDI with MagAO/Clio in L′ and 3.95μm bands. Our achieved contrasts varied between systems, and spanned a range of contrasts from 3.0-7.5 magnitudes and a range of separations from 0.2″to ∼2″. Stars in our survey span a range of masses, and our achieved contrasts correspond to late-type M dwarf masses down to ∼10 MJup. We also report detection of a candidate companion signal at 0.2″(18 AU) around HIP 67506 A (SpT G5V, mass ∼1.2 M⊙), which we estimate to be $\sim 60-90~\mbox{M$_{\rm Jup}$}$. We found that the effectiveness of BDI is highest for approximately equal brightness binaries in high-Strehl conditions.

“…Elders with haemorrhoids are frightened when they experience colorectal bleeding because various diseases may occur with age. They may also associate this experience with symptoms of cancer (Tobal, Pogorelsky, & Tobal, 2008), possibly promoting their helpseeking behaviour. Young people more probably experience anxiety and fear because of their low psychological maturity (Sheldon & Kasser, 2001) when they feel uncomfortable, which can prompt them to seek medical help.…”

Aims This study aimed to describe the status of patient delay and examine related factors affecting patient delay in individuals with haemorrhoids in mainland China, based on theory of planned behaviour and common sense model. Background Studies on patient delay have mainly focused on cancer, tuberculosis and myocardial infarction, but studies on patient delay in individuals with haemorrhoids have yet to be conducted. Compared with other diseases, haemorrhoids are initially considered benign. However, if patients with haemorrhoids seek delayed medical assistance, they pay a large cost for worse symptoms because they fail to seek timely treatments compared with those who receive appropriate treatments at early stages. Design A cross‐sectional study design was used. Methods The current study was performed on 306 patients with haemorrhoids from June ‐ October 2017. Data were collected via a self‐administered pencil‐and‐paper survey that consisted of a multi‐item questionnaire. Stepwise logistic regression analysis was conducted to explore the factors of patient delay. Results Middle‐aged participants were more than twice more likely to report patient delay than participants in other age groups. A high level of perceived self‐efficacy, a high level of illness perceptions and perceived social impact were associated with prolonged delay. Conclusion This study showed that patient delay is common among patients with haemorrhoids in China. The influencing factors of patient delay were middle‐aged, illness perceptions, perceived self‐efficacy, and perceived social impact.
