Collect-and-Distribute Transformer for 3D Point Cloud Analysis
Remarkable advancements have been made recently in point cloud analysis
through the exploration of transformer architecture, but it remains challenging
to effectively learn local and global structures within point clouds. In this
paper, we propose a new transformer network equipped with a
collect-and-distribute mechanism to communicate short- and long-range contexts
of point clouds, which we refer to as CDFormer. Specifically, we first employ
self-attention to capture short-range interactions within each local patch, and
the updated local features are then collected into a set of proxy reference
points from which we can extract long-range contexts. Afterward, we distribute
the learned long-range contexts back to local points via cross-attention. To
address the position clues for short- and long-range contexts, we additionally
introduce the context-aware position encoding to facilitate position-aware
communications between points. We perform experiments on five popular point
cloud datasets, namely ModelNet40, ScanObjectNN, ShapeNetPart, S3DIS and
ScanNetV2, for classification and segmentation. Results show the effectiveness
of the proposed CDFormer, delivering several new state-of-the-art performances
on point cloud classification and segmentation tasks. The source code is

Neural versus pneumatic control of pressure support in patients with chronic obstructive pulmonary diseases at different levels of positive end expiratory pressure: a physiological study
Intrinsic positive end-expiratory pressure (PEEPi) is a "threshold" load that must be overcome to trigger conventional pneumatically-controlled pressure support (PSP) in chronic obstructive pulmonary disease (COPD). Application of extrinsic PEEP (PEEPe) reduces trigger delays and mechanical inspiratory efforts. Using the diaphragm electrical activity (EAdi), neurally controlled pressure support (PSN) could hypothetically eliminate asynchrony and reduce mechanical inspiratory effort, hence substituting the need for PEEPe. The primary objective of this study was to show that PSN can reduce the need for PEEPe to improve patient-ventilator interaction and to reduce both the "pre-trigger" and "total inspiratory" neural and mechanical efforts in COPD patients with PEEPi. A secondary objective was to evaluate the impact of applying PSN on breathing pattern
Last words from Montmartre
When Taiwanese author Qiu Miaojin ended her life in 1995, she left behind her final work, the experimental novel Last Words from Montmartre. This article outlines some of the challenges in translating Qiu Miaojin's novel from Chinese to English. Structured as a series of letters to mirror the novel's own epistolary form, the article discusses how, supported by the novel's constructed chaos, Qiu's narrator occupies several distinct genders over the course of the novel. The authors argue that what might be construed in certain Western literary traditions as the novel's excessive emotionality is in fact a radical act of expression and even resistance to prevailing calls for queer 'reticence' in the time and place of its production
QIU XIAOLONG’S NOVELS: AMERICAN DETECTIVE STORIES WITH CHINESE ROOTS
Qiu Xiaolong is an American writer born in China, but he has been living
in the United States since 1988. He wrote eleven novels about Inspector Chen, who
lives in Shanghai and investigates crimes committed in that city. One of the features of
Qiu Xiaolong’s work is insertions of poetry. Its main character is an educated person,
he writes poetry himself, translates and actively uses the Chinese poetic heritage to
express feelings. The author uses the form of a detective novel to show the various
problems of modern China (the period covered is from the 1990s to the present day)

Natural History. This species can be found inside the dry loose earth around old houses (Figs. 40 G–J; 41 D–E), or in the broad-leaved forest (Fig. 40 A); in the forest, they would like to live together in the tree holes, the humus in the holes is a little wet, but is loose enough for them to creep (Fig. 40 B–D). In Mt. Simianshan, E. hanae were found in a cliff hole, which is difficult to be wetted by the rain, the earth in the hole is wet but loose for E. hanae (Fig. 41 A–C); plenty individuals of E. hanae were also found under the woodpiles next to a farm house at Mt. Simianshan, the earth under the woodpiles is slightly wet and loose, which is mixed with bits of wood (Fig. 41 E); the house-owner said these roaches were not originally live under her woodpiles, they were brought by the owner from the cliff at the hillside. Mt. Simianshan is wet, but the environment under the cliff is dry, the roaches were found inside the sand; the local people call Eupolyphaga roaches as “turtle bugs”, they catch them and put them in the spirit for medicine use, the house-owner also put E. hanae under her woodpiles to breed them for medicine use. Etymology. This species is named after Ms. Jing-Fei Han, who helped the first author collect the type specimens from Dujiangyan. Distribution. China (Sichuan, Chongqing, Guizhou) (Fig. 2). Remarks. A species distributes around Chongqing, Sichuan and Guizhou. This new species was firstly noticed by the first author in Dujiangyan since 2012, but only a photo left (Fig. 40 C). Later from 2015 to 2016, the first author successfully obtained this species from Dujiangyan again (Fig. 40 D–F), and discovered two other populations from Suining, Sichuan and Mt. Simianshan, Chongqing. All the male adults were reared from the nymphs and oothecae were obtained from the females (Figs. 40 E–F, K; 41 F–H). One specimen from GZU was captured from Xishui, where near the border between Sichuan, Chongqing and Guizhou (Fig. 2). Before the present paper is published, a pair of this new species were captured from Mt. Jinyunshan, Chongqing. The two individuals as well as several nymphs were found inside the humus under a stone table in the forest and a nearby small hole under a cliff.Published as part of Qiu, Lu, Che, Yang-Li & Wang, Zong-Qing, 2018, A taxonomic study of Eupolyphaga Chopard, 1929 (Blattodea: Corydiidae: Corydiinae), pp. 1-68 in Zootaxa 4506 (1) on pages 16-18, DOI: 10.11646/zootaxa.4506.1.1, http://zenodo.org/record/260671
Gated relational stacked denoising autoencoder with localized author embedding for global citation recommendation
Citation recommendation is an effective and efficient way to facilitate authors finding desired references. This paper presents a novel neural network based model, called gated relational probabilistic stacked denoising autoencoder with localized author (GRSLA) embedding, for global citation recommendation task. Our model is comprised of two modules with different neural network architecture. For each citing and cited papers, we use a gated paper embedding module, which is extended from probabilistic stacked denoising autoencoder (PSDAE) by adding gated units, to obtain their paper vectors. The added gated units are able to utilize text information of cited paper to refine the vector representation of citing paper in multiple semantic levels. For an author in papers, we first apply topic model to obtain his/her semantic neighbors, and then use a localized author embedding (LAE) module to excavate author vector representation from semantic and explicit neighbors. Unlike most graph convolutional network (GCN) based methods, the LAE module is able to avoid computing global Laplacian in whole graph by taking limited neighbors. Moreover, the LAE module can also be stacked to absorb more neighbors, which makes our model have high extendibility. Based on the generation process of GRSLA, we also derive a learning algorithm of our model by maximum a posteriori (MAP) estimation. We conduct experiments on the AAN, DBLP and CORD-19 datasets, and the results show that GRSLA model works well than previous global citation recommendation methods
