AIM: To investigate the clinical features and surgical outcomes of congenital dysplasia involving both inferior recti(IR) and medial recti(MR) ***: A retrospective review was conducted including cases of simultaneous congenital dysplasia of IR and MR that were diagnosed and surgically treated at the Zhongshan Ophthalmic Center, Sun Yat-sen University, China, from July 2009 to November 2019. Ocular motility, ocular alignment at distance(6 m) and near(33 cm) by prism alternating cover test and stereoacuity were assessed in all patients before and after surgery. RESULTS: A total of five patients(four males and one female;three with right eye and two with left eye congenital dysplasia) were included in this review. The patients ranged in age from 10 to 42 y(21±13.4 y). The main clinical findings were hypertropia and exotropia of the affected eye, along with motility limitations in adduction and depression. Lateral rectus(LR) recession/transposition combined with IR resection was performed in one case. Two scheduled surgeries were performed in four cases, with one involving superior rectus recession and IR resection and the others LR recession and MR resection. Mean±SD pre-surgical exotropia of 51.0±31.11 prism diopter(PD) and hypertropia of 29.20±7.12 PD in the primary position were decreased to 3.6±12.90 and 3.2±10.09 PD, respectively, at two years after surgery, with a success rate of 60% and an undercorrection rate of 40%. CONCLUSION: The main clinical features associated with simultaneous MR/IR congenital dysplasia are hypertropia and exotropia of the affected eye along with motility limitations in adduction and depression. Scheduled two-stage surgeries achieved a success rate of 60%.

研发了一套足尺浅埋管道上拔试验装置,针对不同软土强度、管道埋深和加载方式的情况,较系统地研究了上拔过程中管-土相互作用、管周软土破坏模式、上浮承载力及其影响因素。试验结果表明:在管道上拔过程中,回填软土的变形主要由土块相对位置调整及块间间隙水的排出产生,这与均质软土中变形主要由固结导致明显不同;埋深管径比H/D(28)1时,回填软土的破坏模式接近流动破坏,远小于规范建议的H/D≥3;H/D≥1时,建议采用Palmer方法计算长期荷载作用下回填软土的极限上浮承载力;H/D越大,则回填软土中管道的上浮承载力也越大;在其他条件一定时,回填软土中管道的上浮承载力基本随抗剪强度呈线性增长,由于地基固结速度明显较均质软土快,设计时可适当考虑土体强度恢复的影响。

Allenes are of great importance due to their wide existence in natural products, pharmaceuticals, and molecular materials. Although numerous methods for the preparation of allenes have been developed, they still lag far behind the growing demand in application. Herein, we investigated a palladium catalyzed cross-coupling of vinylbromides with diazo compounds,

Flavor-specific scalar bosons exist in various Standard Model extensions and couple to a single generation of fermions via a global flavor symmetry breaking mechanism. Given this strategy, we propose a Me V flavor-specific scalar model in dimension-5 operator series, which explains the muon g-2 anomaly and proton radius puzzle by coupling with the muon and down-quark at the same time. The framework is consistent with the null result of high-intensity searches. Specifically, the supernova constraints for muon couplings become weakened by including the contribution of down-quark interaction. The parameter space for explaining muon g-2 discrepancy is available when 10% energy deposition is required in the energy explosion process in the supernova,but this is ruled out by the 1% energy deposition requirement. We also investigate the searches for mediator and dark matter and the resulting constraints on viable parameter space such as nuclear physics constraints, direct detection for light boosted dark matter, and possible CMB constraints. When compared with conventional dark matter production, light dark matter production has two additional modifications: bound state formation and early kinetic equilibrium decoupling. We are now looking into the implications of these effects on the relic density of light dark matter.

Given a symmetrizable generalized Cartan matrix A, for any index k, one can define an automorphism associated with A, of the field Q(u1,…, un) of rational functions of n independent indeterminates u1,…,*** is an isomorphism between two cluster algebras associated to the matrix A (see sec. 4 for the precise meaning). When A is of finite type, these isomorphisms behave nicely; they are compatible with the BGP-reflection functors of cluster categories defined in a previous work if we identify the indecomposable objects in the categories with cluster variables of the corresponding cluster algebras, and they are also compatible with the 'truncated simple reflections' defined by Fomin-Zelevinsky. Using the construction of preprojective or preinjective modules of hereditary algebras by DIab-Ringel and the Coxeter automorphisms (i.e. a product of these isomorphisms), we construct infinitely many cluster variables for cluster algebras of infinite type and all cluster variables for finite types.
