The Islamic State of Iraq and Syria (ISIS) relies heavily on propaganda in the form of videos distributed over social media to recruit supporters and new members to its cause, including from the U.S. The U.S. government has countered with anti-ISIS propaganda videos; however, sources claim that the U.S. is losing the propaganda war. We evaluate that claim through a comparative multimodal content analysis of the ISIS video Flames of War and the videos posted in response on the U.S. Department of State’s (USDS) Think Again Turn Away YouTube channel. Our findings shed light on some of the reasons why the USDS anti-propaganda videos are less rhetorically effective than the ISIS videos, including a one-dimensional narrative, a stance that could appear inauthentic, and a lack of sensitivity to Islamic culture. In concluding, we advance recommendations that the USDS could follow to strengthen its online propaganda defense against ISIS, and extend the implications of our findings to other social media fronts where the ISIS vs. USDS propaganda war is being waged.

BACKGROUND There is a lot of health science information in social media. But most of the information lacks persuasive effect. Text features have a great influence on the information. Therefore, the text features of health science information in social media are studied. OBJECTIVE To investigate the text feature of health science information on social media and suggest ways to develop health science information on the basis of the research conclusions. METHODS Using Web crawler to collect the health science information data from WeChat official account, 4,645 myopia prevention texts of children in WeChat were collected, and 813 valid texts were included in the study. Through the analysis of text features, the text sentiment and the use of statistical evidence of health science information were extracted. RESULTS Results show that the use of commendatory words is obviously more than derogatory words (P < 0.01) and statistical evidence was used in over 96% of the text. Suggestions are put forward for the development of health science information in terms of text sentiment and statistical evidence. CONCLUSIONS This study investigated the emotional features of text and statistical evidence use features of health science information in social media. It is found that health information makers prefer positive emotions and use statistical evidence in most texts. Combined with previous research findings, we recommend greater usage of positive emotions and less of statistical evidence when formulating health information.

“Dynamical mixing”, i.e. relaxation of a stellar phase space distribution through interaction with the mean gravitational field, is numerically investigated for a one-dimensional self-gravitating stellar gas. Qualitative results are presented in the form of a motion picture of the flow of phase points (representing homogeneous slabs of stars) in two-dimensional phase space.

Recent progress in the electron-mirror microscopy (EMM), e.g., an improvement of its resolving power together with an increase of the magnification makes it useful for investigating the ferroelectric domain physics. English has recently observed the domain texture in the surface layer of BaTiO3. The present authors ) have developed a theory by which one can evaluate small one-dimensional electric fields and/or topographic step heights in the crystal surfaces from their EMM pictures. This theory was applied to a quantitative study of the surface pattern of BaTiO3).

The synaptic connections in cat retina that link photoreceptors to ganglion cells have been analyzed quantitatively. Our approach has been to prepare serial, ultrathin sections and photograph en montage at low magnification (˜2000X) in the electron microscope. Six series, 100-300 sections long, have been prepared over the last decade. They derive from different cats but always from the same region of retina, about one degree from the center of the visual axis. The material has been analyzed by reconstructing adjacent neurons in each array and then identifying systematically the synaptic connections between arrays. Most reconstructions were done manually by tracing the outlines of processes in successive sections onto acetate sheets aligned on a cartoonist's jig. The tracings were then digitized, stacked by computer, and printed with the hidden lines removed. The results have provided rather than the usual one-dimensional account of pathways, a three-dimensional account of circuits. From this has emerged insight into the functional architecture.

Since the first discovery of high Tc Bi-Sr-Ca-Cu-O superconductor by Maeda et al, many EM works have been done on it. The results show that the superconducting phases have a type of ordered layer structures similar to that in Y-Ba-Cu-O system formulated in Bi2Sr2Can−1CunO2n+4 (n=1,2,3) (simply called 22(n-1) phase) with lattice constants of a=0.358, b=0.382nm but the length of c being different according to the different value of n in the formulate. Unlike the twin structure observed in the Y-Ba-Cu-O system, there is an incommensurate modulated structure in the superconducting phases of Bi system superconductors. Modulated wavelengths of both 1.3 and 2.7 nm have been observed in the 2212 phase. This communication mainly presents the intergrowth of these two kinds of one-dimensional modulated structures in 2212 phase.

Conducting polymers comprises a new class of materials achieving electrical conductivities which rival those of the best metals. The parent compounds (conjugated polymers) are quasi-one-dimensional semiconductors. These polymers can be doped by electron acceptors or electron donors. The prototype of these materials is polyacetylene (PA). There are various other conjugated polymers such as polyparaphenylene, polyphenylenevinylene, polypoyrrole or polythiophene. The doped systems, i.e. the conducting polymers, have intersting potential technological applications such as replacement of conventional metals in electronic shielding and antistatic equipment, rechargable batteries, and flexible light emitting diodes.Although these systems have been investigated almost 20 years, the electronic structure of the doped metallic systems is not clear and even the reason for the gap in undoped semiconducting systems is under discussion.
