About SIF (Solar-Induced Chlorophyll Fluorescence)

"What is SIF?  SIF (Solar induced chlorophyll fluorescence) is an electromagnetic signal emitted by the chlorophyll a of assimilating plants: part of the energy absorbed by chlorophyll a is not used for photosynthesis, but emitted at longer wavelengths as a two-peak spectrum roughly covering the 650–850 nm spectral range." (SENTINEL-5P+ INNOVATION)

650-850nm is the spectral range of SIF.  People collect the data of 687nm, 730-780nm, 760nm, etc.. Some papers mentioned that the emission peaks are 685nm and 740nm. TROPOMI on Sentinel-5P+ collects SIF data emitted from two fitting windows: 743-758 nm window (baseline product) and 735-758 nm.

New device produces critical fertilizer ingredient 'ammonia' from thin air

Today I unexpectedly came across a study: At room temperature and normal atmospheric conditions, ammonia is produced by driving air and water vapor through a catalyst-coated mesh using wind energy. It seems quite interesting, I should read the paper.

今天意外看到一個研究：在室溫及一般大氣的環境下，藉由風能驅動空氣及水氣通過塗有催化劑的網(catalyst-coated-mesh)來產生氨。好像蠻有趣的，應該要來讀paper一下。

Ordinary daily life is a very important treasure

"Ordinary daily life is a very important treasure. Once you lose it, you can never get it back... Once you are no longer around, you will never see it again." (Jobless Reincarnation ~ Use your true skills when you arrive in another world, Volume 14, Chapter 4)

We might think a lot of daily life is just a dull past without anything special. We also take it for granted and think that this is not worth remembering or paying attention to because it will exist naturally. It seems that only those wonderful experiences, special things, or beautiful scenery should remain in memory. However, what we think of as ordinary daily life is an important unit of our existence, and the people and things we come into contact with are the foundation of it. No matter how wonderful your life is, without the support of these ordinary daily lives, it will collapse to the ground like gravel and scatter into unconnected gems.

"平淡無奇的日常生活，是非常重要的寶物。一旦失去，就再也回不來……一旦不在身邊，就再也見不到。"(無職轉生~到了異世界就拿出真本事，第十四卷第四話)

很多的日常生活就只是平淡的過去，沒有任何特殊之處，我們也理所當然的以為這一點都不值得紀念或是重視的，是自然而然地就會存在的，彷彿只有那些精彩的經歷或是特殊的美景才應該留在記憶中。但是啊，我們認為平淡無奇的日常生活，卻是構成我們活著存在的重要單元，在這中間所接觸的人事物，更是其中的基礎。再精采的生活如果沒有這些平淡日常生活的支撐，將如碎石般崩塌於地，散落成無法相連的寶石。

Chinese fishing boats have intruded into Taiwan waters to illegally trawl and quarry sand and gravel repeatedly

Chinese fishing boats have long been crossing the Taiwan Strait border and intruding into Taiwan waters to illegally trawl and quarry sand and gravel. I am furious.

According to a 2017 report by CommonWealth Magazine: Chinese fishing boats are large in tonnage and use the "fast trawl" fishing method, which directly uproots fish and habitats, causing great damage to the ocean.

Based on the principles of ecological conservation and marine protection, the Taiwan government stipulates that Taiwanese fishermen are not allowed to engage in fishing and trawling operations within a certain range, and are not allowed to illegally quarry sand and gravel. However, Chinese fishermen have repeatedly carried out such practices that endanger the marine ecology. Why is the legitimacy of the Taiwanese government's Coast Guard evicting them constantly questioned?

中國漁船長期越界侵入台灣海域進行非法拖網漁船捕撈及盜採砂石，我覺得非常憤怒。

根據天下雜誌2017年的報導：中國漁船的噸位大，用的是「快速拖網」漁法，直接把魚和棲息地連根拔起，對海洋的破壞性大。(https://www.cw.com.tw/article/5082471)

臺灣政府基於生態保育及海洋保護的原則，規範台灣漁民在一定範圍內不准進行捕撈及拖網作業，也不准盜採砂石。但是中國漁民卻屢屢進行這種危害海洋生態的做法，為什麼台灣政府海巡署對其進行驅離時，卻還要被一直質疑其正當性。

Paper: Light stimulation of mitochondria reduces blood glucose levels

This is the abstract of paper published on Feb. 20, 2024 on Journal of Biophotonics: Light stimulation of mitochondria reduces blood glucose levels

Is it true that we could reduce blood sugar level by exposure to 670 nm red light?

<Abstract>
Mitochondria regulate metabolism, but solar light influences its rate. Photobiomodulation (PBM) with red light (670 nm) increases mitochondrial membrane potentials and adenosine triphosphate production and may increase glucose demand. Here we show, with a glucose tolerance test, that PBM of normal subjects significantly reduces blood sugar levels. A 15 min exposure to 670 nm light reduced the degree of blood glucose elevation following glucose intake by 27.7%, integrated over 2 h after the glucose challenge. Maximum glucose spiking was reduced by 7.5%. Consequently, PBM with 670 nm light can be used to reduce blood glucose spikes following meals. This intervention may reduce damaging fluctuations of blood glucose on the body.

Smelly air in Tainan

The air in Tainan is terrible. The north-facing windows smelled like burning things, so we had to close them about 5 minutes ago. The smell of oily smoke from downstairs came from the south-facing window just now, so we had to close it about 1 minute ago.

This has almost become our daily life, a life that is disturbed by unpleasant or unhealthy smells.

台南的空氣真糟糕，5分鐘前，朝北的窗戶傳來陣陣燃燒東西的味道，只好關了。剛剛朝南的窗戶傳來樓下的油煙味，也只好關了。

這幾乎成了我們的日常生活，被臭味薰擾的生活。

Taiwan Election Day

早上9點投完票了。台灣已經投票這麼久了，投票現場還是可以看到選舉亂象。排在我們後面的2位人士，在那裏大放厥詞。

1. 18歲的........。(ps. 還在選舉投票期間，不在此呈現任何意見)

2. 因為我們排隊的地方是分為2條線路，各自對應不同的鄰。右邊那一條前進的很順利，我們這一排不知為什麼停滯不前。後面這2個人就霸占住2條線路，並排聊天。

選務人員請霸佔別區通道的站到我的後面排隊，那個人馬上就反駁，反正這裡也沒有人啊，幹嘛不讓我站。

他的同伴聞言還是將她拉開。然後馬上打臉，後面就有好幾個人陸續往前走，原來就是被他堵住前進的道路。

3. 我們排的這一條一直不會前進，看了幾次，後來看到有選務人員拿著一張椅子，扶著一位年長者去圈選區，想來是花了比較多時間在讓年長者領票。

這時候後面那2個人又開始大聲罵選務人員，說他們是在幹什麼，為什麼都不會前進，效率這麼差。這時候後方較遠處的人也跟著開始傳出喧嘩聲。

我因為剛好已經到進入投票所的入口處，所以可以遠遠看到領票區的情況，就對後面解釋了一下，說有年長者行動不方便。

後方較遠處的人不講話了，但是排在後面的2個人又開始大聲指責，說年長者又怎麼樣，幹嘛因為他們而讓大家排隊等待。不行就不要來。

4. 等到進去排隊蓋章、查驗身分及等待領票。我在第一位選務人員那裏蓋完3個章(要投市長、議員、里長)，往第二位選務人員那裏走過去準備要蓋領公投票的章，我後面的那個人又要插到我前面去先蓋這個章。

I finished voting. Taiwan has been voting for so long, and we could still observe election chaos at the polling site. The 2 people behind us were talking nonsense there.

1. 18 years old...... (ps. During the election voting period, I will not present any opinions here) 2. Because the place where we lined up is divided into 2 lines, each corresponding to a different neighborhood. The one on the right was going well, our row was stuck for some reason. The latter two people occupied the two lines and chat side by side. The election staff asked the one who should stand behind me in the queue, but instead who occupied the path of other neighborhoods. That person immediately retorted and said, "there is no one here anyway, so why don't you let me stand". Hearing this, her companion pulled her away. Then there were several people walking forward one after another right after this. It turned out that she was blocking the way ahead.

3. The line we lined up didn't move forward for a while. After looking at it a few times, I saw an election officer holding a chair and helping an elderly person to the voting desk. At this time, the two people in the back began to scold the election staff loudly, saying what they were doing, why they couldn't move forward, and the efficiency was so poor. At this time, people farther behind also began to make noise. Since I happened to be at the entrance of the polling station, I could see the ticket collection area from a distance, so I explained to the back that some elderly people had difficulty moving. The people farther behind stopped talking, but the two people in the back began to criticize loudly again, saying what about the elders, why did they make everyone wait in line because of them. If not, don't come. 4. Wait until you enter to line up for stamping, identity verification and waiting for ticket collection. I finished stamping 3 stamps at the first electoral officer (to vote for the mayor, council member, and mayor), and walked over to the second electoral officer to stamp the referendum vote, and the person behind me If you want to get ahead of me, write this chapter first.

住戶大會決議公共空間淨空(Residents' meeting resolves public space clearance)

剛開完本大樓住戶大會，會中決議公共空間淨空，在樓梯間及走道上亂放置任何雜物，一律移到1F中庭暫置，會貼出公告請住戶認領。一周內可認領，認領需造冊登記，認領後要收在住戶家中，如果又堆放在公共空間，就交由有關單位開罰。一周內沒有認領，當作廢棄物處理。

這是歷史性的一刻，值得好好慶祝。

It was voted and decided to clear the public space in the resident meeting of the building. Any stuff / debris placed in the stairwell and aisle will be moved to the 1F atrium for temporary storage, and a notice will be posted for residents to claim. It can be claimed within a week by the resident with record. It must be kept in the household of the household after claiming. If it is piled up in the public space again, it will be handed over to the relevant gov agency to impose a fine. If it is not claimed within a week, it will be treated as waste.

This is a historic moment that deserves a good celebration
