Correction: Hospital Stay as a Proxy Indicator for Severe Injury in Earthquakes: A Retrospective Analysis

PLoS ONE (2013)

Lu-Ping Zhao Martin Gerdin Wärnberg Lina Westman José Manuel Rodriguez-Llanes Qi Wu

Introduction: Earthquakes are the most violent type of natural disasters and injuries are the dominant medical problem in the early phases after earthquakes.However, likely because of poor data availability, high-quality research on injuries after earthquakes is lacking.Length of hospital stay (LOS) has been validated as a proxy indicator for injury severity in highincome settings and could potentially be used in retrospective research of injuries after earthquakes.In this study, we assessed LOS as an adequate proxy indicator for severe injury in trauma survivors of an earthquake.Methods: A retrospective analysis was conducted using a database of 1,878 injured patients from the 2008 Wenchuan earthquake.Our primary outcome was severe injury, defined as a composite measure of serious injury or resource use.Secondary outcomes were serious injury and resource use, analysed separately.Non-parametric receiver operating characteristics (ROC) and area under the curve (AUC) analysis was used to test the discriminatory accuracy of LOS when used to identify severe injury.An 0.7,AUC,0.8was defined as adequate.Results: Our study shows that LOS discriminatory accuracy is poor for the primary outcome.However, LOS discriminatory accuracy is adequate for resource use, excluding critical orthopaedic interventions and debridement.Conclusions: Length of hospital stay was not validated as a proxy indicator for severe injury in earthquake survivors.However, LOS was found to be a proxy for major nonorthopaedic surgery and blood transfusion.These findings can be useful for retrospective research on earthquake-injured patients when detailed hospital records are not available.

Benchmarking and Analyzing Point Cloud Classification under Corruptions

arXiv (Cornell University) (2022)

Jiawei Ren Liang Pan Ziwei Liu

3D perception, especially point cloud classification, has achieved substantial progress. However, in real-world deployment, point cloud corruptions are inevitable due to the scene complexity, sensor inaccuracy, and processing imprecision. In this work, we aim to rigorously benchmark and analyze point cloud classification under corruptions. To conduct a systematic investigation, we first provide a taxonomy of common 3D corruptions and identify the atomic corruptions. Then, we perform a comprehensive evaluation on a wide range of representative point cloud models to understand their robustness and generalizability. Our benchmark results show that although point cloud classification performance improves over time, the state-of-the-art methods are on the verge of being less robust. Based on the obtained observations, we propose several effective techniques to enhance point cloud classifier robustness. We hope our comprehensive benchmark, in-depth analysis, and proposed techniques could spark future research in robust 3D perception.

PointAtrousNet: Point Atrous Convolution for Point Cloud Analysis

Elements (2020)

Liang Pan Pengfei Wang Chee–Meng Chew

In this letter, we propose a permutation-invariant architecture-PointAtrousNet (PAN), which focuses on exploiting multi-scale local geometric details for point cloud analysis. Inspired by atrous convolution in image domains, we propose the point atrous convolution (PAC) operation. Our PAC can effectively enlarge the receptive field of filters without introducing more parameters or increasing computation amount. In particular, we propose a novel point atrous spatial pyramid pooling module to explicitly exploit neighboring contextual information at multiple scales. Moreover, local geometric details are captured by constructing neighborhood graphs in metric and feature spaces. Experimental results show that our PAN achieves state-of-the-art performance on various point cloud inference applications.

Neo-Tethyan subduction slab-rollback in the southern Lhasa terrane, Tibet: Perspective from zircon U–Pb geochronology, geochemistry and Sr-Nd-Hf isotopes

Goldschmidt Abstracts (2022)

Peng Fan Bin Zhou Aihua Xi Kui Han Xinxing Qiao

The Yeba volcanic rocks preserve important information of the early Neo-Tethys subduction, which is coeval with the Xiongcun Cu ore-formation in the southern Lhasa terrane.We report the Epingsong volcanic rocks of the southernmost Yeba Formation. of the volcanic rocks were emplaced at ca. 191.4-174.0Ma.All samples obviously have an affinity of the continental margin island-arc, and are rich in LREEs and LILEs but depleted in HFSE.The Yeba andesite is calc-alkaline, medium Mg # (28.3-50.2),and have low Cr (4.68-36.01ppm) and Ni (3.63-12.70ppm), and Eu/Eu* values (1.0-1.13), as well as positive ε Nd value (+3.6) and ε Hf values (-1.3-+10.9).The results indicate that they were probably sourced from the interaction between subducted sediment-derived melts (2-7.5%) and the depleted mantle wedge.The melt was originated from the partial melting of Grt + Sp lherzolite dominated by Sp.The felsic rocks have low Mg # values (19.2-42.3),and MREE depletion (e.g., Tb, Dy and Ho), and Eu/Eu* (0.76-0.96), as well as variable ε Nd values (0.9-2.9) and ε Hf values (2.1-10.4),with two-stage model ages (t DM2 ) of 560-1098 Ma.This implies that the magma is sourced from partial melting of amphibole-rich juvenile crust, accompanied by ancient crystalline basement contamination and crustal assimilation.The Yeba volcanic rocks exhibit slightly bimodal characteristics, and likely record an important tectonic transition from Neo-Tethyan subduction compression to transient extension.Slab-rollback triggers this deep dynamic process.

Nano-Metal–Organic Framework Decorated With Pt Nanoparticles as an Efficient Theranostic Nanoprobe for CT/MRI/PAI Imaging-Guided Radio-Photothermal Synergistic Cancer Therapy

Frontiers in Bioengineering and Biotechnology (2022)

Yingjian Ma Jing Mao Haojie Qin Liang Pan Wenpeng Huang

The multifunctional theranostic nanoplatforms, which can realize changing the contrasts of medical images and enhance cancer therapies simultaneously, have attracted tremendous attention from chemists and medicine in past decades. Herein, a nanoscale metal-organic framework-based material was first synthesized and then decorated with platinum (NMOF545@Pt) successfully for multimodal imaging-guided synergistic cancer therapy. The obtained NMOF545@Pt is advantageous in shortening the longitudinal relaxation time (T1), enhancing photoacoustic effects, and elevating X-ray absorption efficiently. Thus, the enchantments of tripe imaging modalities, computed tomography (CT)/magnetic resonance imaging (MRI)/photoacoustic imaging (PAI), were realized with NMOF545@Pt administration simultaneously and can be cleared from the mice.

Miocene adakitic volcanism in eastern Lhasa Terrane, Tibet: perspective from zircon U–Pb geochronology, whole-rock geochemistry and Sr–Nd–Hf isotopes

Figshare (2022)

Bin Zhou Kui Han Chao-Ming Xie Weipeng Zhu Liang Pan

The Riduo intermediate-felsic volcanic rocks are located in the eastern Lhasa terrane in southern Tibet. Zircon U–Pb dating, geochemical and Sr–Nd–Hf isotope analyses were carried out to constrain the age, petrogenesis and magma source of the Riduo magma suite, including andesite, dacitic tuff, and quartz diorite. Zircon U–Pb dating yielded Early Miocene ages of 19.5 ± 0.5 Ma (andesite), 17.6 ± 0.3 Ma (dacitic tuff), and 15.6 ± 0.5 Ma (quartz diorite). Geochemically, this early Miocene suite is adakitic with high SiO₂ (55.76–69.46 wt.%), Al₂O₃ (15.21–16.61 wt.%), Na₂O (3.82–4.83 wt.%), Sr (427–1033 ppm), and Sr/Y (24.5–145), but low Y (< 17.8 ppm) and Yb (< 1.82 ppm). The rocks also have low to high K₂O (0.44–3.82 wt.%). They are enriched in light rare earth elements (LREEs), large ion lithophile elements (LILEs, e.g. K, Rb, Th and U), but depleted in high-field strength elements (e.g. Nb, Ta) and heavy rare earth elements (HREEs), and have weakly negative to positive Eu anomalies. Isotope analyses reveal that most samples have high whole-rock initial ⁸⁷Sr/⁸⁶Sr ratios (0.705611–0.708807), low ε_Nd(t) (−2.25 to −1.15), and positive zircon ε_Hf (t) (+1.29 to +6.49). We suggest that the early Miocene magmas in the eastern Lhasa terrane were likely sourced from post-collisional partial melting of the juvenile lower crust with minor mantle input. The magmas may have been crustal-contaminated during their ascent to the upper crust along the N-S-trending Cona-Riduo rift.
