Etymology:—The specific epithet commemorates Dr. Peter H. Raven, mentor of the senior author, for his enduring support, guidance, and encouragement, and for his tremendous contribution to botanical research and the conservation of global biodiversity. Chinese name: ⁂武小ª Proposed IUCN conservation status: —Data Deficient (DD). Berberis ravenii is currently known only from the mid-elevation cloud forests in Shuanggui Lake Major Wildlife Habitat and its precise distributional range remains to be explored (IUCN 2012).

Saratov’s plot in Yu. N. Chumakov’s letters
No full textThe article discusses the place of Saratov-based plot in Yu. N. Chumakov’s letters addressed to the author of the article. The subject of discussion in the correspondence is the defense of Yu. N. Chumakov’s dissertation at Saratov University in 1970 and its role in his scientifi c biography. The defense of the dissertation with Yu. M. Lotman as the fi rst opponent became the key event of the Saratov plot and its climax. Having singled out fragments from the correspondence related to the plot of Saratov, the author seeks to explain the direction of the ensuing epistolary dialogue, why the defense of the dissertation was perceived by Yu. N. Chumakov as a more than signifi cant event for him, especially in the context of his dramatic biography. The author proves that the defense was an explosion of the linear sequence of the text of life, which dramatically changed the fate of the scientist. The desire to talk in detail about the defense, to fi nd out what impression it made, and to look at what was happening on that memorable day for him through the eyes of the addressee of the letter, betrayed the desire to read and interpret his fate again and again. Particular attention is paid in the correspondence to the personalities of such outstanding philologists, professors of Saratov University as A. P. Skaftymov and E. I. Pokusaev. Yu. N. Chumakov was not A. P. Skaftymov’s student and was not familiar with him, but specifi cally noted the acquisition and subsequent development of the principles of a scientifi c approach to the work, set out in his theoretical article in 1923. About the personality of E. I. Pokusaev, his supervisor, and the history of the relationship with him, Yu. N. Chumakov wrote in great detail. Having told about the role of E. I. Pokusaev, who supported the dissertation at the defense, and having outlined his complex, large and humanly attractive personality, Yu.N. Chumakov completes the plot of Saratov, which was very meaningful for him, primarily for self-understanding of his scientifi c path
Fables: Fong Siue-Fong
No full textI already have a similar book with English translations of Feng Hsueh-Feng, now here written Fong Siue-Fong. In fact, I have it in a hardbound first edition of 1953 and a paperbound second edition of 1955. Here is the hardbound French edition of 1955. The artist in those editions was called Huang Yung-yu; here he is Houang Yong-yu. The translator is not here acknowledged. This copy adds a picture of the author at the head of two new pages devoted to him. Surprisingly, the first full-page illustration -- for Le Paysan, les Moineaux et les Alouettes -- is reduced in size (5). Not all of the printer's designs used in the second edition are used here, perhaps because some texts run longer on the page. The order of fables seems to differ from the respective orders in the English editions. As I mention there, the fables are often directly admonitory and/or of a highly political slant. Un Rat Original may have the best illustration (77). Among the most overtly political is the fable on the imperialist weasel munching a duckling (26-8); here again the illustration is reduced, this time to fit horizontally and not vertically onto its page. There is a T of C at the back. The Foreign Languages Press in 1983 also did a paperbound version in smaller format but using the same illustrations, and I have that edition too.This is a hardbound book (hard cover)Language note: FrenchOriginal language: chiStated first editionFong Siue-Fon

No full textNitrogen-vacancy center has proven a promising candidate in quantum information and quantum sensing due to its excellent optical and spin properties for long coherent time and robust spin state readout, as well as its sensitivity towards multiple tunable parameters such as magnetic field, electric field, mechanical strain and pressure. In this thesis, we study the change of diamagnetic properties of single crystal BaFe₂(As₀.₅₉P₀.₄₁)₂ under high pressure at cryogenic condition by using micron-sized diamond particles as spatially resolved magnetic probes. In addition, we review advanced spin coherent control and readout techniques using cavity quantum electrodynamics in literatures. At last, we demonstrate the interplay between quantum optimal control and machine learning.We extract vectorial information of the local magnetic field at different position on the sample from ODMR spectrum. Through tuning pressure parameter and performing thermal cycle, we determine the lower critical field c₁ and lower critical temperature c₁, together with c₂ dependence of the sample as a function of pressure. This novel sensing technique utilizing NV centers overcomes technical difficulties of employing conventional fragile magnetic probes under extreme pressure, while being a local vector field sensor and readily accessible to most confocal or wide-field microscopy setups. On the other hand, we use deep reinforcement learning and active learning to study the feasibility and outlook for quantum optimal control and suggest hybrid approach to improve current standalone algorithms and methods.鑽石中氮-空缺中心是一個極具潛力的量子工具，其優越的光學及自旋特性使其在量子資訊與測量均受廣泛應用和研究。 本論文將利用微米大小的鑽石顆粒來測量單晶體BaFe₂(As₀.₅₉P₀.₄₁)₂ 在高壓和低溫下的抗磁性特點。另外，我們會做一些簡短的文獻評論來敘述氮-空缺中心與量子電動力學的互補作用。最後，我們會探討如何使用機器學習來達到量子最優控制。我們從光學磁共振的光譜分析在樣本不同位置的局部向量磁場。通過調校壓力和溫度，得出下臨界磁場c₁和下臨界溫度c₁；並取得c₂跟壓力的關係圖。這項新的測量方法解決在高壓下難以使用脆弱的磁力計的問題，同時提供便利的磁向量測量方案。另一方面，我們將利用深度強化學習和主動學習來探索它們在量子最優控制的可行性及其潛質；並提議混合的方法來改善現有單一的算法。Yu, King Yiu = 量子資訊科技基於鑽石中氮-空缺中心 / 余經燿.M.Phil.

Local subspace identification of distributed homogeneous systems with general interconnection patterns
No full textThis paper studies the local identification of large-scale homogeneous systemswith general network topologies. The considered local system identification problem involves unmeasurable signals between neighboring subsystems. Compared with our previous work in Yu et al. (2014) which solves the local identification of 1D homogeneous systems, the main challenge of this work is how to deal with the general network topology. To overcome this problem, we first decompose the interested local system into separate subsystems using some state, input and output transform, namely the spatially lifted local system has block diagonal system matrices.We subsequently estimate the Markov parameters of the local system by solving a nuclear norm regularized optimization problem. To realize the state-space system model from the estimated Markov parameters, another nuclear norm regularized optimization problem is provided by taking into account of the inherent dependence of a redundant parameter vector. Finally, the overall identification procedure is summarized.Accepted Author ManuscriptTeam Michel Verhaege

The Power of Market Intermediaries: The Influence of Awards on Participants and Category Evolution in the U.S. Book Market
No full textOur conception of categories structures every part of our lives, and among markets that are generally categorized by categories, most studies focus on the product level, with less discussion of the category level. However, focusing on the product level, or on a single set of market participants and products, limits our understanding of the evolution of entire categories, and makes it difficult to understand how categories change between emergence and demise. This paper constructs a panel data set from 2007 to 2021 comprising Goodreads' book and review data, combining three representative and well-known book awards, and adding Amazon's bestseller list data to measure whether the awards' conferring of category status affects producers' and audiences' choices of categories by fixed-effects Poisson model, as well as the impact on the levels within categories, to find out the process of category evolution. By examining producers' and audiences' reactions to the conferring of category status, it is hoped to fill in the gaps in the concept of category growth. The data results show that awards do influence producers' and audiences' choices of product categories, and that category growth comes from the wider use of labels by producers and audiences as categories obtain conferred status
