Nonlinear Analysis of Single Reinforced Concrete Piles Subjected to Lateral Loading
Ling-Yu Xu,Fei Ca,Guo-Xin Wang,Guo-Xing Chen,Yong-Yi Li 대한토목학회 2017 KSCE JOURNAL OF CIVIL ENGINEERING Vol.21 No.7
This paper proposes a method for the nonlinear analysis of laterally loaded single reinforced concrete piles based on the beam-onnonlinear- Winkler-foundation approach. A nonlinear fiber beam-column element is used to model the nonlinear behavior of a pile. The pile is divided into a series of segments, of which the cross section is assumed to be plane and normal to the longitudinal axis. The internal force of a segment is derived by integrating the nonlinear stress-strain relationships of all steel and concrete fibers within the cross section of the segment. The substructure technique is introduced to calculate the stiffness matrix of the segments. The nonlinear behavior of soils surrounding the pile is characterized by a modified strain wedge model. The results show that (1) the predicted results using the proposed method are consistent with the measurements for all three full-scale tested piles, and (2) updating the neutral axis of segments has a significant effect on the calculated lateral deflection; however, it has a slight effect on the calculated bending moment. Moreover, an empirical equation is derived from the numerical analyses for estimating the cracked flexural rigidity of bored piles subjected to lateral loading.
Limiting Attribute Disclosure in Randomization Based Microdata Release
Ling Guo,Xiaowei Ying,Xintao Wu 한국정보과학회 2011 Journal of Computing Science and Engineering Vol.5 No.3
Privacy preserving microdata publication has received wide attention. In this paper, we investigate the randomization approach and focus on attribute disclosure under linking attacks. We give efficient solutions to determine optimal distortion parameters, such that we can maximize utility preservation while still satisfying privacy requirements. We compare our randomization approach with i-diversity and anatomy in terms of utility preservation (under the same privacy requirements) from three aspects (reconstructed distributions, accuracy of answering queries, and preservation of correlations). Our empirical results show that randomization incurs significantly smaller utility loss.

Three new cyanide-bridged CrIIIMnII binuclear complexes, [Mn(phen)2Cl][Cr(bpmb)(CN)2]·H2O (1) (phen = 1,10-phenanthroline, bpmb2– = 1,2-bis(pyridine-2-carboxamido)-4-methyl-benzenate), [Mn(phen)2Cl][Cr(bpdmb)- (CN)2]·H2O (2) (bpdmb2– = 1,2-bis(pyridine-2-carboxamido)-4,5-dimethyl-benzenate), and [Mn(phen)2Cl]- [Cr(bpClb)(CN)2]·CH3OH·H2O (3) (bpClb2– = 1,2-bis(pyridine-2-carboxamido)-4-chloro-benzenate) were obtained based on Mn(phen)2Cl2 and a series of dicyanidechromate(III) building blocks. Single crystal X-ray diffraction analysis shows the structures of the three complexes are dimeric type with two different metal centers linked by a cyanide group from corresponding dicyanidechromate(III) building block. Magnetic investigations indicate the existence of relatively weak antiferromagnetic coupling between Cr(III) and Mn(II) ions with best-fit constants JCrMn = –2.78(5) cm–1 for 1, JCrMn = –3.02(2) cm–1 for 2 and JCrMn = –2.27(3) cm–1 for 3 based on the spin exchange Hamiltonian = –2JCrMn Cr Mn. The magneto-structural correlation of cyanide-bridged CrIIIMnII complexes has been discussed at last.

个人合伙纠纷司法困境之破解对策 — 兼论《民法典》合伙合同章立法完善
Guo Ling 제주대학교 법과정책연구원 2022 국제법무 Vol.14 No.2
The personal financial accounting system of the partnership is not perfect, and the partnership property cannot be divided because it cannot be liquidated when the partnership is dissolved. Courts often reject partners’ demands for division of partnership property on the grounds that they can’t liquidate, resulting in personal partnership disputes falling into the judicial dilemma of judges refusing to adjudicate. To solve the dilemma, we must start from three aspects: legislative perfection, contract autonomy, and case guidance. The provisions of the Civil Code on partnership are listed in Part I General Provisions and Part III Contract Law. The provisions of the General Provisions are applicable to the partnership enterprises. The Contract Law has the chapter of partnership contract to adjust the partnership that has not formed an organization. The individual partnership belongs to an unorganized partnership, which shall be adjusted according to the provisions of the partnership contract. There are twelve articles in the partnership contract chapter. Articles 972, 973 and 978 of the Civil Code together constitute the rules for the termination of partnership property distribution. Article 973 stipulates that the partners shall be jointly and severally liable for the partnership debts. The provisions of Articles 972 and 978 on the distribution of partnership property among partners do not guarantee the partners’ property distribution right. The liquidation of unorganized partnerships is not mandatory by law. This kind of arrangement has advantages and disadvantages: the advantage lies in giving partners maximum freedom to conclude partnership contracts, and independently deciding the number and content of contract terms; The disadvantage is that the important clauses of the partnership contract are not shown to the partners. From the practical effect, the disadvantages outweigh the advantages. Model clauses of partnership contracts should be added to the chapter of partnership contracts in the Civil Code, and the liquidation clause should be shown as an important contract content. Under the guidance of the model clauses of partnership contract in the Civil Code, partners should fully negotiate important contract clauses, make detailed arrangements for partnership affairs, and make detailed agreements in partnership contracts. Personal partnership disputes in judicial difficulties are caused by unclear financial accounting accounts and uncertain profits and losses of the partnership. To avoid the disputes falling into a dilemma, partners should clearly stipulate important matters such as partnership financial accounting, liquidation procedures, liability for liquidation, and distribution ratio of partnership property in the partnership contract when concluding the contract, so as to provide a contractual basis for future dispute resolution. Meanwhile The Supreme People’s Court should issue guiding cases about individual partnership disputes, manage individual partnership disputes by summarizing the main points of judgment, and correct the wrong trial idea of refusing judgment on the grounds that it can’t be liquidated.

A position-sensitive CsI(Tl) crystal array coupled with the multi-anode position sensitive photomultiplier tube (PS-PMT), Hamamatsu H8500C, has been developed at the Institute of Modern Physics. An effective, fast, and economical readout circuit based on discretized positioning circuit (DPC) bridge was designed for the 64-channel multi-anode flat panel PSPMT. The horizontal and vertical position resolutions are 0.58 mm and 0.63 mm respectively for the 1.0 × 1.0 × 5.0 ㎣ CsI(Tl) array, and the horizontal and vertical position resolutions are 0.86 mm and 0.80 mm respectively for the 2.0 × 2.0 × 10.0 ㎣ CsI(Tl) array. These results show that the CsI(Tl) crystal array with low cost could be applied in the fields of medical imaging and high-resolution gamma camera.

Yunnan Baiyao is a famous Chinese medicine that has long been directly applied to wounds to reduce bleeding, pain, and swelling without causing infection. However, little is known about its ability to prevent infection. The present study aimed to assess in vitro the anti-virulence activity of an aqueous extract of Yunnan Baiyao (YBX) using Pseudomonas aeruginosa as a pathogenic model. We found that a sub-MIC (2.5 mg/ml) of YBX can efficiently interfere with the quorum-sensing (QS) signaling circuit. Real-time polymerase chain reaction analysis showed that a sub-MIC of YBX downregulated the transcriptions of lasR, lasI, rhlR, and rhlI,which resulted in global attenuation of QS-regulated virulence activities, such as biofilm formation, and secretion of LasA protease, LasB elastase and pyocyanin. Further, YBX reduced the motility of P. aeruginosa related to QS, and impaired the formation of biofilms. These results suggest that YBX may possess global inhibitory activity against the virulence of P. aeruginosa and that YBX may also exhibit antimicrobial activity in vivo. The present study suggests that Yunnan Baiyao represents a potential source for isolating novel, safe, and efficacious antimicrobial agents.
