Features in "Ask the Expert" forums, and future consideration
This research is a case study that identified features found in "Ask the Expert" online forms. The research is based on an analysis of a sample of 20 "Ask the Expert" forums and previous investigations. The research identified a total of 21 features found in the sample of 20 online forums. These features were categorized as very common, common, uncommon, and very uncommon based on the percentage of the forums that exhibited them. The results did not find a relationship between the number of features a forum has and the topic of discipline of the forum. The discussion examines the advantages, user interface design issues, and possible problems with various features. The research concludes with a discussion of features that might be implemented in online forums and the identification of related research topics
Color 3D Printing: Theory, Method, and Application
Our research team proposes a colored manufacturing technology with a layer-by-layer printing process. Using digital inkjet printing in layer-by-layer printing color graphics, a further low-cost color 3D Printing (3DP) technology can be developed. It can provide an integrated way to prototype and reproduce 3D objects, from concept to design and manufacturing. Ultimately, with fast graphics printing method, it guarantees a feasible way to further promote cultural and creative products
Heterospecific alarm-call recognition in two warbler hosts of common cuckoos
International audienceSpecies facing similar selection pressures should recognize heterospecific alarm signals. However, no study has so far examined heterospecific alarm-call recognition in response to parasitism by cuckoos. In this study, we tested whether two sympatric host species of the common cuckoo Cuculus canorus, Oriental reed warbler Acrocephalus orientalis (ORW, main host), and black-browed reed warbler Acrocephalus bistrigiceps (BRW, rare host), could recognize each other's alarm calls in response to cuckoos. Dummies of common cuckoo (parasite) and Eurasian sparrowhawk Accipiter nisus (predator) were used to induce and record alarm calls of the two warbler species, respectively. In the conspecific alarm-call playback experiments, ORW responded more strongly to cuckoo alarm calls than to sparrowhawk alarm calls, while BRW responded less strongly to cuckoo alarm calls than to sparrowhawk alarm calls. In the heterospecific alarm-call playback experiments, both ORW and BRW responded less strongly to cuckoo alarm calls than sparrowhawk alarm calls. BRW seemed to learn the association between parasite-related alarm calls of the ORW and the cuckoo by observing the process of ORW attacking cuckoos. In contrast, alarm calls of BRW to cuckoos were rarely recorded in most cases. BRW with low parasite pressure still developed recognition of heterospecific parasite-related alarm call. Unintended receivers in the same community should recognize heterospecific alarm calls precisely to extract valuable information
Automated identification and quantification of myocardial inflammatory infiltration in digital histological images to diagnose myocarditis
This study aims to develop a new computational pathology approach that
automates the identification and quantification of myocardial inflammatory
infiltration in digital HE-stained images to provide a quantitative
histological diagnosis of myocarditis.898 HE-stained whole slide images (WSIs)
of myocardium from 154 heart transplant patients diagnosed with myocarditis or
dilated cardiomyopathy (DCM) were included in this study. An automated DL-based
computational pathology approach was developed to identify nuclei and detect
myocardial inflammatory infiltration, enabling the quantification of the
lymphocyte nuclear density (LND) on myocardial WSIs. A cutoff value based on
the quantification of LND was proposed to determine if the myocardial
inflammatory infiltration was present. The performance of our approach was
evaluated with a five-fold cross-validation experiment, tested with an internal
test set from the myocarditis group, and confirmed by an external test from a
double-blind trial group. An LND of 1.02/mm2 could distinguish WSIs with
myocarditis from those without. The accuracy, sensitivity, specificity, and
area under the receiver operating characteristic curve (AUC) in the five-fold
cross-validation experiment were 0.899 plus or minus 0.035, 0.971 plus or minus
0.017, 0.728 plus or minus 0.073 and 0.849 plus or minus 0.044, respectively.
For the internal test set, the accuracy, sensitivity, specificity, and AUC were
0.887, 0.971, 0.737, and 0.854, respectively. The accuracy, sensitivity,
specificity, and AUC for the external test set reached 0.853, 0.846, 0.858, and
0.852, respectively. Our new approach provides accurate and reliable
quantification of the LND of myocardial WSIs, facilitating automated
quantitative diagnosis of myocarditis with HE-stained images.Comment: 21 pages,5 figures,6 Tables, 25 reference
Quality Health Information On the Internet: Developing a Diabetes Pathfinder For the Chinese Population
A Web-based bilingual diabetes information pathfinder was created to help the Chinese population access quality health information on the Internet as part of a collaborative outreach project in the Dallas-Fort Worth area. A survey was conducted to identify the demographics, Internet usage, health information needs, and preferences for training sessions of the Chinese population. Breast cancer, diabetes, and hepatitis B were the top three diseases of interest. The process of developing the pathfinder is described from start to finish, and it can serve as a model for the development of others. Pathfinder training sessions also were held.

Anomalous thermal Hall effect and anomalous Nernst effect of CsVSb
Motived by time-reversal symmetry breaking and giant anomalous Hall effect in
kagome superconductor \textit{A}VSb (\textit{A} = Cs, K, Rb), we
carried out the thermal transport measurements on CsVSb. In addition to
the anomalous Hall effect, the anomalous Nernst effect and the anomalous
thermal Hall effect emerge. Interestingly, the longitudinal thermal
conductivity largely deviates from the electronic contribution
obtained from the longitudinal conductivity by the
Wiedemann-Franz law. In contrast, the thermal Hall conductivity
is roughly consistent with the Wiedemann-Franz law from electronic
contribution. All these results indicate the large phonon contribution in the
longitudinal thermal conductivity. Moreover, the thermal Hall conductivity is
also slightly greater than the theoretical electronic contribution, indicating
other charge neutral contributions. More than that, the Nernst coefficient and
Hall resistivity show the multi-band behavior with possible additional
contribution from Berry curvature at the low fields
