Image plays an important role in news articles. Appropriate image arrangements can well transmit scene information and help readers understand more clearly. This paper proposes a neural model based on the cross-modal RNN equipped with an encoding updating mechanism to insert images into proper positions of a news document sequentially. For each image, our model selects the position of which the surrounding sentences are most relevant to the image. Two methods are employed to score the relevance between the image and surrounding sentences: the one employs a layer of convolution network before scoring, and the other employs the pooling operation after the scoring. It is reasonable to believe that inserting an image in news will render the information of the news. We hence introduce an updating mechanism to update the encoding of the news document after the image is inserted. To the best of our knowledge, we are the first to focus on the news image locating problem, as well as provide a feasible solution. We create the dataset for the problem by extending the DailyMail corpora and carry out experiments. Experiments show that the proposed model outperforms four baselines including the pointer network according to two evaluation metrics. The code is released on Github11https://github.com/njupt-summ/ImageLocating.

A low-volume low-mass low-power ultra-high-frequency radio transceiver for future planetary missions is described. The project targets a volume of less than 10 , mass of less than 50 grams, and power consumption of 50 mW on receive and 100 mW, 300 mW, or 3 W on transmit (for 10 mW, 100 mW, and 1 W output options). The transmitter design supports convolutionally coded binary phase-shift keying (BPSK), RC-BPSK, and quadrature phase-shift keying transmission from 1 to 256 kbps. Command/control instructions can be received at 2 or 8 kbps, with a sensitivity of better than 120 dBm. In addition to its low volume/mass/power features, temperature compensation to 100 C and radiation tolerance to 100 krad allow operation outside of thermally controlled, shielded enclosures, further reducing the mass and complexity of exploration vehicles. The design is described in a top-down format, beginning with system requirements and proceeding through digital modem algorithm development, discussion of the silicon-on-sapphire CMOS process used and elaboration of key blocks in the radio-frequency (RF) integrated circuit design. Techniques to address coupling between high-sensitivity RF and on-chip digital circuits are also presented, and test results are given for prototypes of all major functions. Although designed for the Martian environment, the transceiver is expected to be useful in other proximity links where a small low-power radio compatible with Prox-1 space-link protocols is desired.
