BACKGROUND Cetuximab in combination with oral fluoropyrimidine(FP)remains controversial in metastatic colorectal cancer(mCRC).In view of the regional variation in the tolerability of FP,we conducted a retrospective analysis to compare oral FP with infusional FP in combination with cetuximab in Chinese *** To compare the efficacy and safety profile of cetuximab in combination with oral FP and infusional FP in Chinese population in the real-world *** A retrospective cohort study was done to analyse consecutive patients with Kras wild-type mCRC who received first-line treatment with cetuximab and FP-based chemotherapy in our unit from January 2010 to December ***-five eligible patients were *** median follow-up of our cohort was 65.0 *** The median progression-free survival(mPFS)and median overall survival(mOS)of the entire cohort were 9.66 mo(95%CI:7.72–12.5)and 25.8 mo(95%CI:18.7–35.6),*** oral FP and infusional FP,there was no statistical significant difference in the mPFS[9.79 mo(95%CI:7.49–12.7)vs 9.63 mo(95%CI:6.34–13.4);P=0.72]and mOS[25.8 mo(95%CI:15.2–35.6)vs 26.3 mo(95%CI:18.7–41.2);P=0.63].Grade 3 or above adverse events were reported in 28.4%of patients,being similar with oral and infusional FP,and included 10.5%of neutropenia and 2.1%of diarrhoea *** The current analysis demonstrates comparable efficacy and safety profiles of cetuximab in combination with oral and infusional FP in Chinese *** results expand treatment options for Chinese patients and invite revision of existing treatment guidelines to incorporate oral FP-based chemotherapy plus cetuximab.

作者： Zan Zhou Thomas Man-Hoi lok Wan-Huan Zhou Department of Civil and Environmental Engineering Faculty of Science and TechnologyUniversity of MacaoMacaoChina

Surface wave inversion is a key step in the application of surface waves to soil velocity ***,a common practice for the process of inversion is that the number of soil layers is assumed to be known before using heuristic search algorithms to compute the shear wave velocity profile or the number of soil layers is considered as an optimization ***,an improper selection of the number of layers may lead to an incorrect shear wave velocity *** this study,a deep learning and genetic algorithm hybrid learning procedure is proposed to perform the surface wave inversion without the need to assume the number of soil ***,a deep neural network is adapted to learn from a large number of synthetic dispersion curves for inferring the layer ***,the shear-wave velocity profile is determined by a genetic algorithm with the known layer *** applying this procedure to both simulated and real-world cases,the results indicate that the proposed method is reliable and efficient for surface wave inversion.

A path planning algorithm for a crop monitoring fixed-wing unmanned aerial system

引用

Science China(Information Sciences) 2024年第8期67卷 5-23页

作者： Longhao QIAN Yi lok LO Hugh Hong-tao LIU Institute of Aerospace Studies University of Toronto Department of Mechanical Engineering The University of Hong Kong

With the growing demand for automation in agriculture, industries increasingly rely on drones to perform crop monitoring and surveillance. In this regard, fixed-wing unmanned aerial systems(UASs)are viable platforms for scanning a large crop field, given their payload capacity and range. To achieve maximum coverage without landing for battery replacement, an algorithm for producing a minimal required energy survey path is essential. Hence, an energy-aware coverage path planning algorithm is proposed *** constraints for a fixed-wing UAS to fly at low altitudes while achieving full coverage of the crop field are first analyzed. Then, the full path is decomposed into straight-line and U-turn primitives. Finally, an algorithm to calculate a combination of straight-line segments and U-turns is proposed to obtain the path with minimum required energy consumption. The genetic algorithm is used to efficiently determine the order of the straight-line paths to traverse. Case studies show that the proposed algorithm can produce planning results for a convex-polygon-shaped crop field.

Epitranscriptomic Regulation of NMDA Receptors Rears its Ugly Head in Chemotherapy-Induced Neuropathic Pain

A number of different cancer chemotherapy agents such as cisplatin,oxaliplatin,and paclitaxel can lead to nerve damage,thereby giving rise to neuropathic pain states that present with mechanical and cold allodynia[1].Although these pain conditions often resolve after completion of the chemotherapy,a significant portion of patients exhibit longlasting pain that can persist longer than 12 months with a negative impact on the quality of life of affected individuals[1].
