Mujie Qi, genitalia slide Nos. QMJ18016 ³, QMJ18017 ♀, QMJ18021 ♀. Diagnosis. This species is similar to F. bicoloralis in the male and female genitalia, but it can be distinguished in the male genitalia by the uncus slightly concave in middle laterally, the horn-shaped basolateral process of the uncus, the valva setose before apical process and on distal 1/3 of the ventral area; and in the female genitalia by the antrum wider than colliculum and about 2 times its length. In F. bicoloralis, the uncus is convex laterodistally, the rather slim basolateral process of the uncus is finger-shaped, and the valva has sparse setae on distal 1/5–1/6 of the ventral area (Fig. 9); the antrum is slenderer than the colliculum and about 2.5 times as long as the colliculum (Fig. 14).

Ductus bursae membranous, anterior 1/4 scobinate on inner surface, posterior 3/4 slightly wrinkled. Corpus bursae rounded, about 1/10 length of ductus bursae; signum rounded, with long thorn medially, with numerous spinules becoming smaller from center to edge. Distribution. China (Tibet). Etymology. The specific name is derived from the Latin cornutus (horn-shaped) and procerus (projecting), in reference to the horn-shaped process at base of uncus.Published as part of Qi, Mujie & Li, Houhun, 2019, Taxonomic study of the genus Fujimacia Marumo, 1939 (Lepidoptera: Pyralidae) in China, with descriptions of four new species, pp. 171-181 in Zootaxa 4661 (1) on pages 173-175, DOI: 10.11646/zootaxa.4661.1.9, http://zenodo.org/record/337863
Newton’s method for computing the nearest correlation matrix with a simple upper bound
No full textThe standard nearest correlation matrix can be efficiently computed by exploiting a recent development of Newton’s method (Qi and Sun in SIAM J. Matrix Anal. Appl. 28:360–385, 2006). Two key mathematical properties, that ensure the efficiency of the method, are the strong semismoothness of the projection operator onto the positive semidefinite cone and constraint nondegeneracy at every feasible point. In the case where a simple upper bound is enforced in the nearest correlation matrix in order to improve its condition number, it is shown, among other things, that constraint nondegeneracy does not always hold, meaning Newton’s method may lose its quadratic convergence. Despite this, the numerical results show that Newton’s method is still extremely efficient even for large scale problems. Through regularization, the developed method is applied to semidefinite programming problems with simple bounds
Lê Quý Đônova teorija li-qi
No full textThis paper discusses the work of Lê Quý Đôn (1726–1784), a prominent scholar of Later Lê Vietnam who was deeply influenced by Song-Ming Neo-Confucianism. Lê’s masterwork, the Classified Discourses from Yun Terrace (Yuntai leiyu 芸臺類語, Vân đài loại ngữ), exemplifies this intellectual heritage. This essay considers the text’s first volume in light of Zhu Xi’s theory of li-qi. While drawing deeply from Zhu Xi’s theory of an inseparable li-qi, Lê’s concept of li-qi ultimately originated in Han dynasty qi-transformative cosmology. Also influenced by a Vietnamese tradition of Three Teachings syncretism, Lê integrated Neo-Confucianism with Han cosmology to create a unique li-qi theory.Članek obravnava delo priznanega učenjaka Lê Quýja Đôna (1726–1784) s konca vietnamske dinastije Le, na katerega je močno vplivalo neokonfucijanstvo dinastij Song in Ming. Ta idejna zapuščina se kaže v Lejevem mojstrskem delu Razvrščene razprave iz terase Vinske rutice (Yuntai leiyu 芸臺類語, Vân đài loại ngữ). Članek obravnava prvi zvezek tega dela, in sicer na podlagi Zhu Xijeve teorije o liju in qiju. Čeprav je Lê Quý Đôn izhajal iz Zhu Xijeve teorije o neločljivosti lija in qija, Lejev koncept lija in qija izvira iz transformativne kozmologije, ki se je razvila v dinastiji Han. Le je pod vplivom vietnamske tradicije sinkretizma Treh naukov neokonfucijanstvo povezal s hansko kozmologijo ter ustvaril edinstveno teorijo lija in qija
