Shape retrieval using multi-level included angle functions-based Fourier descriptor

An effective shape signature namely multi-level included angle functions MIAFs is proposed to describe the hierarchy information ranging from global information to local variations of shape.Invariance to rotation translation and scaling are the intrinsic properties of the MIAFs.For each contour point the multi-level included angles are obtained based on the paired line segments derived from unequal-arc-length partitions of contour.And a Fourier descriptor derived from multi-level included angle functions MIAFD is presented for efficient shape retrieval.The proposed descriptor is evaluated with the standard performance evaluation method on three shape image databases the MPEG-7 database the Kimia-99 database and the Swedish leaf database. The experimental results of shape retrieval indicate that the MIAFD outperforms the existing Fourier descriptors and has low computational complexity.And the comparison of the MIAFD with other shape description methods also shows that the proposed descriptor has the highest precision at the same recall value which verifies its effectiveness.

Nonlinear stability of advanced sandwich cylindrical shells comprising porous functionally graded material and carbon nanotube reinforced composite layers under elevated temperature

The nonlinear stability of sandwich cylindrical shells comprising porous functionally graded material(FGM) and carbon nanotube reinforced composite(CNTRC)layers subjected to uniform temperature rise is investigated. Two sandwich models corresponding to CNTRC and FGM face sheets are proposed. Carbon nanotubes(CNTs) in the CNTRC layer are embedded into a matrix according to functionally graded distributions. The effects of porosity in the FGM and the temperature dependence of properties of all constituent materials are considered. The effective properties of the porous FGM and CNTRC are determined by using the modified and extended versions of a linear mixture rule, respectively. The basic equations governing the stability problem of thin sandwich cylindrical shells are established within the framework of the Donnell shell theory including the von K’arm’an-Donnell nonlinearity. These equations are solved by using the multi-term analytical solutions and the Galerkin method for simply supported shells.The critical buckling temperatures and postbuckling paths are determined through an iteration procedure. The study reveals that the sandwich shell model with a CNTRC core layer and relatively thin porous FGM face sheets can have the best capacity of thermal load carrying. In addition, unlike the cases of mechanical loads, porosities have beneficial effects on the nonlinear stability of sandwich shells under the thermal load. It is suggested that an appropriate combination of advantages of FGM and CNTRC can result in optimal efficiency for advanced sandwich structures.

Efficacy of invisible advancement correction for mandibular retraction in adolescents based on Pancherz analysis

BACKGROUND Mandibular retraction is the main etiological mechanism of class II malocclusion in China and the subsequent distal molar relationship can cause functional discomfort in mastication,breathing and the temporomandibular joint.The use of mandibular advancement(MA)devices has recently emerged as an adolescent mandibular retraction treatment;however,current studies regarding the effect thereof are relatively few,and there is lack of sufficient clinical support.AIM To investigate the clinical effect of invisalign MA on the treatment of mandibular retraction in adolescents.METHODS This study included 30 adolescent patients who underwent treatment with the MA appliances from December 2017 to June 2021.The lateral cephalometric data before and after treatment were collected and imported into Dolphin Imaging software.The changes were measured by linear measurement superimposed with lateral cephalometric trajectory based on the Pancherz technology.RESULTS There was no significant difference in the length and position of maxilla before and after the treatment.The position of the mandible moved 3.13 mm,the length increased 4.14 mm,the mandibular ramus length increased 4.09 mm,the body length increased 4.25 mm,and the position of the condyle moved 1.03 mm forward after treatment.Additionally,changes in the incisor sagittal position and labial inclination were observed.The position of the upper incisor point moved back 1.33 mm,without statistical difference,the inclination and tooth angle decreased by 3.44°and 4.06°,respectively;the position of the lower incisor point was moved 2.98 mm,and the inclination and tooth angle increased by 2.62°and 1.23°,respectively.Furthermore,changes in the incisor overjet and molar relationship were seen.Overjet decreased by 4.31 mm,of which 1.78 mm was due to dental factors,accounting for 41.3%of the effect as opposed to 58.7%due to skeletal factors.Molar relationship improved 3.87 mm,with 1.34 mm due to dental factors,and dental and skeletal factors were accounted for 34.6%and 65.4%of the effect,respectively.CONCLUSION For adolescent patients with mandible retraction,invisalign MA can effectively promote the mandible growth,and it was proven to be mainly due to skeletal effects.

Designing Advanced Liquid Electrolytes for Alkali Metal Batteries:Principles,Progress,and Perspectives

The ever-growing pursuit of high energy density batteries has triggered extensive efforts toward developing alkali metal(Li,Na,and K)battery(AMB)technologies owing to high theoretical capacities and low redox potentials of metallic anodes.Typically,for new battery systems,the electrolyte design is critical for realizing the battery electrochemistry of AMBs.Conventional electrolytes in alkali ion batteries are generally unsuitable for sustaining the stability owing to the hyper-reactivity and dendritic growth of alkali metals.In this review,we begin with the fundamentals of AMB electrolytes.Recent advancements in concentrated and fluorinated electrolytes,as well as functional electrolyte additives for boosting the stability of Li metal batteries,are summarized and discussed with a special focus on structure-composition-performance relationships.We then delve into the electrolyte formulations for Na-and K metal batteries,including those in which Na/K do not adhere to the Li-inherited paradigms.Finally,the challenges and the future research needs in advanced electrolytes for AMB are highlighted.This comprehensive review sheds light on the principles for the rational design of promising electrolytes and offers new inspirations for developing stable AMBs with high performance.

目的研究基于既病防变思想的健脾行气解毒法对中晚期原发性肝癌患者的作用效果。方法选取安阳市中医院2019年4月至2023年4月收治的80例中晚期原发性肝癌患者,随机分为对照组和观察组,对照组(40例)接受索拉非尼联合放疗,观察组(40例)联合基于既病防变思想的健脾行气解毒法治疗,对比两组中医证候积分、肝功能、肿瘤标志物水平、复发转移情况和不良反应发生率。结果治疗后,观察组谷草转氨酶(GOT)、谷丙转氨酶(GPT)、总胆红素(TBil)、细胞角蛋白19片段抗原21-1(CYFRA21-1)、甲胎蛋白(AFP)、糖类抗原199(CA199)水平均低于对照组(P<0.05),肿瘤复发转移率及中医证候积分低于对照组(P<0.05);两组不良反应发生率比较差异无统计学意义(P>0.05)。结论基于既病防变思想的健脾行气解毒法治疗中晚期原发性肝癌患者的效果确切,能够降低中医证候积分,改善肝功能,降低肿瘤标志物水平和肿瘤复发转移率,安全性高,具有临床推广价值。

西黄胶囊联合XP方案治疗晚期胃癌的近期疗效及对外周血肿瘤标志物、细胞免疫功能和血管生成调节因子的影响

目的:探讨西黄胶囊联合卡培他滨+顺铂(XP方案)治疗晚期胃癌的近期疗效及其对患者外周血肿瘤标志物、细胞免疫功能和血管生成调节因子水平的影响。方法:选择2019年1月至2022年3月北京航天总医院收治的晚期胃癌患者152例,以随机数字表法分为观察组和对照组,每组76例。对照组患者给予XP方案治疗,观察组患者在对照组的基础上联合西黄胶囊治疗,21 d为1个疗程。连续治疗4个疗程后进行近期疗效评价,治疗过程中记录两组患者的不良反应情况。治疗前后检测两组患者血清肿瘤标志物[糖类抗原(CA)19-9、CA72-4和癌胚抗原(CEA)]、细胞免疫功能[外周血CD3^(+)、CD4^(+)、CD8^(+)T细胞百分比和CD4^(+)/CD8^(+)比值]及血清血管生成调节因子[血管内皮生长因子(VEGF)、碱性成纤维细胞生长因子(bFGF)和转化生长因子-β1(TGF-β1)]水平,并随访记录两组患者的远期生存情况。结果:观察组患者的客观缓解率、疾病控制率分别为51.32%(39/76)、93.42%(71/76),显著高于对照组的30.26%(23/76)、82.89%(63/76),差异均有统计学意义(P<0.05)。观察组患者白细胞减少、血小板减少和胃肠道反应的发生率显著低于对照组,差异均有统计学意义(P<0.05)。治疗后,两组患者CA19-9、CA72-4和CEA,VEGF、bFGF和TGF-β1水平均较治疗前显著降低,观察组患者较对照组降低更为显著,差异均有统计学意义(P<0.05)。治疗后,观察组患者外周血CD3^(+)、CD4^(+)水平及CD4^(+)/CD8^(+)比值均较治疗前显著升高,且显著高于对照组,差异均有统计学意义(P<0.05)。观察组患者中位无进展生存期、中位总生存期分别为6.1、12.9个月,均较对照组(4.7、9.8个月)显著延长,差异均有统计学意义(P<0.05)。结论:西黄胶囊联合XP方案治疗晚期胃癌患者,能有效抑制血清肿瘤标志物水平,调控血管生成调节因子的表达,改善机体细胞免疫功能,提高近期疗效及远期生存获益,且表现出一定的减毒作用。
