The political role of the people's liberation army 1949-1973
Full text linkThis thesis is to study the political role of the People's Liberation Army from the approach of structure and function. The framework of the thesis consists of three major parts, first, the influence of Chinese traditional political culture on, and the formation of, the political role of the PL A; second, the influence of domestic political struggles and external military conflicts on the development of the political role of the PLA; and the third, the analysis of the transition of the PLA's political role from the structure and personnel arrangements of the CCPCC Within the above-mentioned three scopes, this thesis make a thorough discussion on the following: (1) The relationship between the structure of the PRC and the formation of the PLA's political role; (2) How has ideology influenced the army's political role; (3) What is Mao's viewpoint and his influence on the development of the army's political role; (4) What is the link between the army and the party, and how has this developed; (6) What accounts for the expansion of the PLA's political functions; (7) What is the influence of political factional struggles on the PLA's political role; (8) Is it political institution or military institution that controls the recruitment of the military elite; (9) What are the disparities between the military elite in handling international conflicts and what are their political considerations; (10) What is the Party's position in the army; (11) How have the Party’s important meetings and personnel arrangements influenced the rise and fall of the PLA's political role
The phase transition in Chung-Lu graphs
Full text linkIn 2002, Chung and Lu introduced a version of the Erdos-Renyi model which an
edge between and is present with probability . They applied
this model to compute the diameter of power-law random graphs, with yielded
easier proofs than those for the configuration model. In 2007 their model was
brought and integrated under the umbrella of Bolobas, Janson, and Riordan's
inhomogeneous random graphs. However, the properties of the Chung-Lu model were
never fully explored. In this paper, we fill the gap by giving a result for the
cluster sizes in the subcritical regime and the fraction of vertices in the
giant component in the supercritical phase
Blazing a Trail via Matrix Multiplications: A Faster Algorithm for Non-shortest Induced Paths
Full text linkFor vertices and of an -vertex graph , a -trail of is an induced -path of that is not a shortest -path of . Berger, Seymour, and Spirkl [Discrete Mathematics 2021] gave the previously only known polynomial-time algorithm, running in time, to either output a -trail of or ensure that admits no -trail. We reduce the complexity to the time required to perform a poly-logarithmic number of multiplications of Boolean matrices, leading to a largely improved -time algorithm.18 pages, 6 figures, a preliminary version appeared in STACS 202
Sedum triangulisepalum T. S. Liu & N. J. Chung ex T. C. Hsu & S. W. Chung 2022, sp. nov.

Chung ” in Chen <i>et al.</i> (2017: 329, as <i>triangulosepalum</i>), <i>nom. inval.</i>].</p> <p> <b>Type:</b> — TAIWAN. Hualien County: Hsiulin Township, Lo-ma-wan Shan, 1800 m elev., 15 June 1973, <i>N.J. Chung 280</i> (holotype: NTUF!, barcode: F00008307; isotypes: NTUF!, eight sheets, barcodes: F00008308–F00008315).</p> <p> <b>Diagnosis:</b> — <i>Sedum triangulisepalum</i> is similar to <i>S. truncatistigmum</i> T.S. Liu & N.J. Chung (1977: 23) in sharing epiphytic life-form, alternate and ±flattened leaves and fused calyx, while the former is readily distinguished in having longer calyx (1.5–2.0 vs. 0.8–1.0 mm) that are only fused at the base (vs. nearly entirely fused).</p> <p> <b>Morphological descriptions and illustrations:</b> —This species has been described by Liu & Chung (1977: 21) and illustrated by Tang & Huang (1989: 27, pl. 15, as <i>Sedum microsepalum</i>), Chen <i>et al.</i> (2017: 329) and Ito <i>et al.</i> (2017: 11, fig. 1D).</p> <p> <b>Distribution and ecology:</b> — <i>Sedum triangulisepalum</i> is endemic in Taiwan, where it occurs in the northern and eastern portions of the main island and usually grows on tree trunks in montane cloud forests at 500–2000 m elev. (Liu & Chung 1977; Chen <i>et al.</i> 2017; Ito <i>et al.</i> 2017).</p> <p> <b>Etymology:</b> —The specific epithet is composed of two Latin elements: <i>triangulus</i>, triangular, and <i>sepalum</i>, sepal, referring to its triangular calyx lobes. It should be spelt as “ <i>triangulisepalum</i> ” instead of “ <i>triangulosepalum</i> ” as originally published by Liu & Chung (1977) according to Art. 60.10 of the ICN.</p> <p> <b>Note:</b> —Two gatherings, “ <i>Suzuki s.n.</i> ” collected from Wulai and “ <i>Chuang 280</i> ” collected from Lomawanshan, were cited under <i>Sedum triangulisepalum</i> by Liu & Chung (1977), and “ <i>Chuang 280</i> ” is presumably a typo of “ <i>Chung 280</i> ” since the “ <i>N.J. Chung 280</i> ” gathering, collected by the second original author and currently preserved in NTUF, matches well with the data given in the original publication (Liu & Chung 1977). There are nine duplicates of <i>Chung 280</i>, including one (barcode: F00008307) labelled as “ holotype ” and the others (barcodes: F00008308–F00008315) as “isotype”. Although these labels could not be archived as the legitimate designation of types as they are not effectively published (see Art. 7.10 of the ICN), they supposedly reflect the original author’s intention and are thus adopted here. Images of all type materials are available in the “Plants of Taiwan ” database [http://tai2.ntu.edu.tw].</p>Published as part of <i>Hsu, Tian-Chuan & Chung, Shih-Wen, 2022, Validation of the name Sedum triangulosepalum (Crassulaceae), pp. 215-216 in Phytotaxa 547 (2)</i> on page 215, DOI: 10.11646/phytotaxa.547.2.10, <a href="http://zenodo.org/record/6571375">http://zenodo.org/record/6571375</a>
Central limit theorem for the principal eigenvalue and eigenvector of Chung-Lu random graphs
Full text linkA Chung–Lu random graph is an inhomogeneous Erdős–Rényi random graph in which vertices are assigned average degrees, and pairs of vertices are connected by an edge with a probability that is proportional to the product of their average degrees, independently for different edges. We derive a central limit theorem for the principal eigenvalue and the components of the principal eigenvector of the adjacency matrix of a Chung–Lu random graph. Our derivation requires certain assumptions on the average degrees that guarantee connectivity, sparsity and bounded inhomogeneity of the graph.</p

An optimal algorithm for the maximum-density segment problem
No full textWe address a fundamental problem arising from analysis of biomolecular sequences.
The input consists of two numbers wmin & wmax & a sequence S of n number pairs (ai, wi)
with wi > 0. Let segment S(i, j) of S be the consecutive subsequence of S between indices i
and j. The density of S(i, j) is d(i, j) = (ai + ai+1 + · · · + aj )/(wi + wi+1 + · · · + wj ). The
maximum-density segment problem is to find a maximum-density segment over all segments S(i, j)
with wmin ≤ wi + wi+1 + · · · + wj ≤ wmax..
