| 1 | Diode-pumped wavelength-switchable visible Pr^(3+):YLF laser and vortex laser around 670 nm显示文摘Here we developed a novel wavelength-switchable visible continuous-wave(CW)Pr^(3+):YLF laser around 670 nm.In single-wavelength laser operations,the maximum output powers of 2.60 W,1.26 W,and 0.21 W,the maximum slope efficiencies of 34.7%,27.3%,and 12.3%were achieved with good beam qualities(M^(2)<1.6)at 670.4 nm,674.2 nm,and 678.9 nm,respectively.Record-high output power(2.6 W)and record-high slope efficiency(34.7%)were achieved for the Pr^(3+):YLF laser operation at 670.4 nm.This is also the first demonstration of longer-wavelength peaks beyond 670 nm in the^(3)P_(1)→^(3)F_(3)transition of Pr^(3+):YLF.In multi-wavelength laser operations,the dual-wavelength lasings,including 670.1/674.8 nm,670.1/679.1 nm,and 675.0/679.4 nm,were obtained by fine adjustment of one/two etalons within the cavity.Furthermore,the triple-wavelength lasings,e.g.672.2/674.2/678.6 nm and 670.4/674.8/679.4 nm,were successfully demonstrated.Moreover,both the first-order vortex lasers(LG_(0)^(+1)and LG_(0)^(-1)modes)at 670.4 nm were obtained by off-axis pumping. | Xiuji Lin Qichen Feng Yao Zhu Shuaihao Ji Bo Xiao Huiying Xu Wensong Li Zhiping Cai | 2021 | Opto-Electronic Advances2021，4，4： | 4 |
| 2 | On L(1, 2)-Edge-Labelings of Some Special Classes of Graphs显示文摘For a graph G and two positive integers j and k, an m-L(j, k)-edge-labeling of G is an assignment on the edges to the set {0,..., m}, such that adjacent edges receive labels differing by at least j, and edges which are distance two apart receive labels differing by at least k. The λ′j,k-number of G is the minimum m of an m-L(j, k)-edge-labeling admitted by G.In this article, we study the L(1, 2)-edge-labeling for paths, cycles, complete graphs, complete multipartite graphs, infinite ?-regular trees and wheels. | Dan HE Wensong LIN | 2014 | Journal of Mathematical Research with Applications2014，34，4： | 2 |

| 9 | Polystyrene microsphere-immobilized palladium(Ⅱ)porphyrin as mild,reusable,and highly efficient catalyst for Heck reaction显示文摘A novel Heck reaction catalyst consisting of a palladium(Ⅱ) complex of meso-tetra(phydroxyphenyl)porphyrin(MTP) and cross-linked chloromethylated polystyrene microspheres(PMs) was successfully prepared via covalent ether bonds between the chloride groups in the PMs and the hydroxyl groups in MTP.The catalyst was characterized using scanning electron microscopy,Fourier-transform infrared spectroscopy,and inductively coupled plasma atomic emission spectroscopy(ICP-AES).This polystyrene-supported palladium-complex was an efficient heterogeneous catalyst for cross-coupling of aryl iodides with ethyl acrylate.The reaction of iodobenzene and ethyl acrylate under N_2 at 100 ℃ and a catalyst concentration of 0.1%gave a gas chromatography product yield of 99.8%,which is much higher than that achieved using a free palladium(Ⅱ) complex of MTP as the catalyst(41.3%).The catalyst was recycled up to six times without significant loss of catalytic activity.These results suggest that the immobilized palladium(Ⅱ)-MTP catalyst has potential applications in synthetic and industrial chemistry. | Yinbin Huang Liangrong Yang Minghui Huang Jian Wang Lin Xu Wensong Li Huacong Zhou Xitong Sun Huifang Xing Huizhou Liu | 2015 | Particuology2015，13，5： | 1 |

| 13 | The Injective Chromatic Index of a Claw-Free Subcubic Graph is at Most 6显示文摘A coloring of edges of a graph G is injective if for any two distinct edges e1 and e2,the coloring of e1 and e2 are distinct if they are at distance 2 in G or in a common 3-cycle.The injective chromatic index of G is the minimum number of colors needed for an injective edge coloring of G.It was conjectured that the injective chromatic index of any subcubic graph is at most 6.In this paper,we partially confirm this conjecture by showing that the injective chromatic index of any claw-free subcubic graph is less than or equal to 6.The bound 6 is tight and our proof implies a linear-time algorithm for finding an injective edge coloring using at most 6 colors for such graphs. | Xiaoyuan DONG Yuquan LIN Wensong LIN | 2023 | Journal of Mathematical Research with Applications2023，43，4： | 0 |
| 14 | Outcomes of two-stage double-level rotational osteotomy in treating patients with congenital proximal radioulnar synostosis显示文摘Congenital proximal radioulnar synostosis(CPRUS)is a rare anomaly which is caused by abnormal fusion of the proximal radius and ulna during development.This is due to the failure of embryological separation,resulting in the fixed position of the forearm,from mild to severe pronation.1Mild deformity leads to slight disability because the shoulder and wrist can effectively compensate.2 Patients with bilateral cases and/or pronation defor-mity of>60°may be severely limited in daily activities.34 Most surgeons recommend surgical intervention when the loss of forearm rotation exceeds 60°,particularly when the forearm is fixed in pronation. | Hu Bo Jingfang Xu Jianlan Lin Weiwei Zhu Zhefeng Zhen Wensong Ye Wenhao Chen | 2023 | World Journal of Pediatric Surgery2023，6，2： | 0 |
| 15 | Experimental study on failure characteristics of single-sided unloading rock under different intermediate principal stress conditions显示文摘Investigation of unloading rock failure under differentσ_(2)facilitates the control mechanism of excavation surrounding rock.This study focused on single-sided unloading tests of granite specimens under true triaxial conditions.The strength and failure characteristics were studied with micro-camera and acoustic emission(AE)monitoring.Furthermore,the choice of test path and the effect ofσ_(2)on fracture of unloading rock were discussed.Results show that the increasedσ_(2)can strengthen the stability of single-sided unloading rock.After unloading,the rock’s free surface underwent five phases,namely,inoculation,particle ejection,buckling rupture,stable failure,and unstable rockburst phases.Moreover,atσ_(2)≤30 MPa,the b value shows the following variation tendency:rising,dropping,significant fluctuation,and dropping,with dispersed damages signal.Atσ_(2)≥40 MPa,the tendency shows:a rise,a decrease,a slight fluctuation,and final drop,with concentrated damages signal.After unloading,AE energy is mainly concentrated in the micro-energy range.With the increasedσ_(2),the micro-energy ratio rises.In contrast,low,medium and large energy ratios drop gradually.The increased tensile fractures and decreased shear fractures indicate that the failure mode of the unloading rock gradually changes from tensile-shear mode to tensile-split one.The fractional dimension of the rock fragments first increases and then decreases with an inflection point at 20 MPa.The distribution of SIF on the planes changes asσ_(2)increases,resulting in strengthening and then weakening of the rock bearing capacity. | Chongyan Liu Guangming Zhao Wensong Xu Xiangrui Meng Zhixi Liu Xiang Cheng Gang Lin | 2023 | International Journal of Mining Science and Technology2023，33，3： | 0 |
| 16 | Main Components and Antioxidant Activity of Callisia repens Extracts显示文摘To study the main active components and antioxidant activity in vitro of extracts from Callisia repens , the contents of main active components such as total flavonoids, total anthocyanin and total sugar in the extracts were studied by spectrophotometry. The components and content of 18 kinds of metals were determined by ICP-MS mass spectrometry. Finally, the oxidative activity of the extract was evaluated by spectrophotometry. Results showed that the content of flavonoids, the total protein, the total sugar and the total anthocyanin in C. repens extract powder were 2.04%, 1.83%, 55.2% and 7.2%, respectively. Beneficial trace elements such as Ca, Mn, Mg in C. repens extracts were higher, while harmful heavy metals such as Pb, Hg, Ag, Co, Ge were very tiny or not detected at all. The IC 50 of C. repens was 0.265 mg/mL for scavenging DPPH·, and 1.16 mg/mL for scavenging ·OH free radical, the total reducing power of 1 mg extract was equivalent to that of 39 μg of Vc, and the extract showed no regular chelating power to ferrous ions. In conclusion, C. repens extracts have high content of natural active components, but extremely low content of the harmful heavy metals, and C. repens extract has good antioxidant capacity. Its antioxidant activity is realized by a variety of active factors through a synergistic mechanism. Thus, C. repens extract has great potential for developing into functional foods. | Bo LENG Shaoru CAI Xiumin LI Jiafu HUANG Yu XUE Zhichao LIN Wensong CHEN Chunxian LI Yutian PAN | 2019 | Asian Agricultural Research2019，11，7： | 0 |
