- (En) Multistability in the lactose utilization network of Escherichia coli
The assignment of PHY2709 Quantitative Biology. It is a brief paper reading report of Ozbudak EM, Thattai M, Lim HN, Shraiman BI, Van Oudenaarden A. Multistability in the lactose utilization network of Escherichia coli. Nature. 2004 Feb 19;427(6976):737-40. doi: 10.1038/nature02298. PMID: 14973486.
- (En) A brief review of kinesin research
The final project of PHY2018 Stochastic Processes. Thanks for Prof Anton Zilman’s valuable comments and I tried to improve this post according them. For an introduction of kinesin from a biological view, check the Chinese post 细胞生物学.

- 玉兰 Yulania denudata (Desrousseaux) D. L. Fu
物理楼前的春景
- 龙爪槐 Sophora japonica
我最喜欢的乔木物种！
- 八角金盘 Fatsia japonica （Thunb.）Decne. et Planch
叶有 7-9 深裂纹，我数了，确实是，所以为什么叫“八角金盘”？
- 蜡梅 Chimonanthus praecox (Linn.) Link
放寒假时开花。
- 红枫 Acer palmatum 'Atropurpureum'
秋季颜色变红，叶子有 7 个分岔。
- 秤锤树 Sinojackia xylocarpa Hu
直到看到果实才直到俗名的来源。
- 棕榈 Trachycarpus fortunei (Hook.) H. Wendl.
我本不想记录第十个物种了，但是突然从形态学上发现这种树雌雄异株，特此记录。
- 木犀 Osmanthus fragrans (Thunb.) Loureiro
桂花开了？
- 荷花玉兰 Magnolia grandiflora L
在北方还没有见过，学校里到处都是。白色的花很显眼。
- 栾树 Koelreuteria paniculata
果期挂满树梢的果实还是很引人注目的。
- 爬墙虎 Parthenocissus tricuspidata
北大楼的代表形象。
- 水杉 Metasequoia glyptostroboides Hu & W. C. Cheng
说实话，给我留下最深刻印象的特点是高耸。
- 日本榧 Torreya nucifera (L.) Sieb. et Zucc
榧 fei 三声
- 法桐 Platanus × acerifolia
这种落叶乔木的存在感很强。
- 银杏 Ginkgo biloba L.
今天有人去捡白果吗？
- 香樟 Cinnamomum camphora (Linn) Presl
树干上的苔藓给人留下一种“陈旧”的印象。

- (En) Period and extrema by nonlinear ODEs
Given a system of nonlinear ODEs that generates a limit cycle oscillation, can we find out the period and the extrema of the variables, without numerically solving the ODEs in time?
- (En) Linear response
Our purpose here is to explore the more general case of time dependent influences. As we’ll see, by studying the response of the system at different frequencies… –David Tong’s Lecture 4
- (En) Gene regulatory networks described by jump process and fluctuation dissipation theorem
The content of this post is closely linked to the research conducted by A. Hilfinger, J. Paulsson, and J. Elf, etc. As a mathematical rookie, I will introduce the models and mathematics in the most accessible way. You need a second-year undergrad level of mathematics to read this.
- (En) How is the significance of fluctuations near chemical instability captured by Gillespie algorithm?
I have applied the Gillespie algorithm for about three years to simulate stochastic chemical reactions or more coarse-grained gene regulatory networks. I think it is a good point to check Gillespie’s important original papers and write a report about some of my thoughts…

A great opportunity for me to re-learn Mathematical Methods for Physicists, or even linear algebra…
- (En) hilfinger2011separating
I started an interesting new category - supplementary mathematics of supplementary information of selected papers, abbr. as “Supp-of-Supp”. I am writing down page after page of detailed but non-trivial mathematical derivations for the non-intuitive equation that suddenly appears and kills me when reading the papers, which are closely related to my research topics and similar crucial mathematical skills.
