About Endosymbiotic Gene Transfer (EGT)

It is very interesting, I didn’t know that mitochondria and chloroplast would do this before. Please check the following links yourself if you want to know more.

很有趣啊，我以前都不知道 Mitochondria and Chloroplast 會這樣做啊，請大家自己看下面的連結及說明。

Suppression of plastid-to-nucleus gene transfer by DNA double-strand break repair (https://www.nature.com/articles/s41477-025-02005-w)

"Abstract: Plant nuclear genomes contain thousands of genes of mitochondrial and plastid origin as the result of endosymbiotic gene transfer (EGT). EGT is a still-ongoing process, but the molecular mechanisms determining its frequency remain largely unknown. Here we demonstrate that nuclear double-strand break (DSB) repair is a strong suppressor of EGT. Through large-scale genetic screens in tobacco plants, we found that EGT from plastids to the nucleus occurs more frequently in somatic cells when individual DSB repair pathways are inactive. This effect is explained by the expected increase in the number and residence time of DSBs available as integration sites for organellar DNA. We also show that impaired DSB repair causes EGT to increase 5- to 20-fold in the male gametophyte. Together, our data (1) uncover DSB levels as a key determinant of EGT frequency, (2) reveal the strong mutagenic potential of organellar DNA and (3) suggest that changes in DNA repair capacity can impact EGT across evolutionary timescales."

葉綠體基因搬家時：核基因體如何決定「接不接受」這份大禮？(https://vocus.cc/article/68298bf0fd89780001fa74fc)

"在植物演化史上，有個默默進行了幾十億年的大搬家工程──葉綠體和粒線體裡的基因，陸續轉移到細胞核裡，這個過程叫做內共生基因轉移（Endosymbiotic Gene Transfer, EGT）。雖然我們已經知道這件事發生了很久、很久、很久，也看到許多核基因帶有葉綠體或粒線體的痕跡，但一個問題始終沒有明確答案：這些基因是怎麼進去的？又為什麼有時候轉移得多，有時候轉移得少？"

Transition from Trait to Environment (TTE)

Let's read this report by IRRI, "IRRI Scientists Introduces New Breeding Approach to Harness Genomic Selection in Challenging Environments".

They develop a new breeding approach, called “Transition from Trait to Environment (TTE)”.

Figure 1. Breeding schemes for developing flood-tolerant genotypes. (A) Traditional method: a submergence-tolerant donor is crossed with high-yielding lines to combine traits. (B) Redesigned approach: elite genotypes with fixed submergence tolerance are intercrossed, and progenies are evaluated under natural flooding to select for yield and agronomic performance. Trait submergence tolerance is already fixed among the parental genotypes. (https://ricetoday.irri.org/irri-scientists-introduces-new-breeding-approach-to-harness-genomic-selection-in-challenging-environments/)

這是為了提高作物對氣候變遷的耐受度，也就是提高作物適應逆境環境。在育種時，傳統育種是先從高產量的品系開始，然後再慢慢加入能適應逆境的性狀來做篩選。TTE則是直接從能適應逆境的作物開始，再去篩選出高產量的後代，此時因為親代本來就都帶有適應逆境的基因，所以所有的子代都能適應逆境，此時只要專注於篩選出高產量的即可。

The Constitution of the Taiwan (ROC)

When the Constitution of the ROC was first drafted, it emphasized the independence of the five powers.  The legislative power has become dominant now, overriding the executive, judicial, supervisory, and examination powers. Isn't this strange?

Article 57 of the Constitution regulates the methods of questioning, reconsideration, and confirmation. Why do I feel that the current chaos is due to the abuse of Article 57? Maybe my understanding of the legal provisions and text is not accurate enough.

中華民國的憲法一開始在制定時，就強調五權分立，但是現在卻變成立法權獨大，凌駕行政、司法、監察及考試權之上，這樣不會很奇怪嗎？

憲法第57條的規範，規範了質詢、覆議、覆議之決議方式，為什麼我怎麼看都覺得現在的亂象是因為濫用第57條啊。有可能是我對法律條文及文字的理解不夠精確吧。

---------------- https://law.moj.gov.tw/ENG/LawClass/LawAll.aspx?pcode=A0000001 ----

The New Rice variety: Climate-smart Jaspe

Jaspe, a new rice variety developed in Chile, can thrive in dry and cold environments, maintain high yields in drought conditions, and reduce CH4 emissions. I need to read their published paper to make sure if it can also maintain good growth in dry and hot environments, or continue to produce abundant yields in variable dry-wet environment.

As for the description of its yield, the news said that Jaspe produces 30 ears of rice. I need to read their published paper to make sure if the number and weight of grains per ear of rice are the same as the ordinary rice it is compared with. If so, it really has 10 times the yield as it claims.

智利培育出來的新品種水稻 "氣候智慧型水稻" Jaspe，能在乾燥、寒冷的環境裡生長旺盛，在乾旱情況下維持的產量，同時達到減排。不知道是否也能在乾旱炎熱的環境裡維持良好的生長，或是在多變的乾濕環境下繼續產量豐富。

至於其產量的描述，Jaspe產出30株稻穗，不知每株稻穗的穀粒數及重量是否和其拿來比較的一般稻米一樣多，如果是，那就真的如其所說有10倍產量了。

Safety of Li Battery

This news is reported today because it's currently suspected that the fire was caused by Li battery inside the air monitoring equipment, even it is still under investigation. This makes me think of the Li battery safety certification issues I've recently encountered at work. Because it is required to self-charging the Li batteries inside our equipment continuously, we're planning to use ternary lithium batteries (NMC). Currenty, I am busy evaluating various certifications like UL 2580, UL2271, UL 62133-2, and IEC 62133-2.  I think they might have used the higher energy density ternary lithium battery (LiNiCoMnO2) instead of the lower energy density but safer lithium iron phosphate battery (LiFePO4).

Here's the news:

On April 14, 2025, a large fire occurred in Yangmingshan, Taipei. It's suspected that the lithium battery in the solar power module of an air quality sensor belonging to the National Center for High-performance Computing (NCHC) under the National Science and Technology Council caused it. The NCHC has removed 16 air quality sensors with built-in lithium batteries installed in Hsinchu City, Nantou County, Tainan City, and Chiayi County, and has strengthened its control measures. 
https://news.ltn.com.tw/news/politics/breakingnews/5053708 
https://news.pts.org.tw/article/752885

I did a quick check, and it seems they were using iAeris air quality monitoring equipment: https://www.niar.org.tw/xmdoc/cont?xsmsid=0I148622737263495777&sid=0P104624748119528484  https://www.sysinnotec.com/iaeris3

今天會刊出這個新聞，是因為目前懷疑是設備裡面的鋰電池造成失火，不過詳細結果還待後續偵辦確認。想到最近工作上遇到的鋰電池安全認證議題，由於是需要能持續自動充電的鋰電池，所以規劃使用三元鋰電池。最近正在努力評估 UL 2580、UL2271、UL62133-2、IEC62133-2 等不同的認證。我覺得他們是使用能量密度較高的三元鋰電池(NMC, LiNiCoMnO2)，沒有使用能量密度較低但安全性較高的磷酸鐵鋰電池(LiFePO4)。

新聞內容：

4/14/2025臺北市陽明山小油坑發生大火，懷疑是國科會旗下國網中心的空氣品質感測器中的太陽能供電模組的鋰電池所引起，國網中心已拆除安裝在新竹市、南投縣、台南市及嘉義縣的16支內建鋰電池的16支有鋰電池的空品感測器，並加強管控。

A referendum for nuke

Honestly, I really don't want to keep discussing whether nuclear power is expensive or not; what to do about high-level, medium-level, and low-level nuclear waste with nowhere to dispose of or store it (the NIMBY problem); or whether Taiwan, with its frequent magnitude 5-7.x earthquakes and numerous fault lines, is even suitable for continuing to operate old nuclear power plants that have had many issues and are already decommissioned or scheduled for decommissioning.

But the KMT and TPP parties simply refuse to let the third Nuclear Power Plant be decommissioned, and now they even want a referendum to keep it running. It's truly infuriating. Please don't force people to accept problems that cannot be solved by science and technology now. Just because you win a vote doesn't mean the scientific and technical problems are magically resolved.

I saw a few lines today that I found quite amusing regarding nuclear power:

-----

The pro-nuclear side has always had a logical dilemma:

1. Taipower is terrible and full of lies.
2. Taipower-managed nuclear power plants are super safe and will have no problems.

--------

其實不想一天到晚討論核能發電到底貴不貴、低中高階核廢料找不到地方處置及儲存要怎麼辦(NIMBY)、常常發生5-7.x級地震且擁有超多斷層的臺灣是否適合讓過去發生過許多問題且已停機及除役的老舊核電廠繼續運轉，但是白藍政黨就是完全不想讓核三廠除役，還要公投讓核三廠繼續運轉，真是令人厭煩。科學技術上無法解決的問題，請不要繼續強人所難，並不是說投票投贏了，科學技術的問題就解決了。今天看到下面的幾句話，覺得很有趣。

關於核能，擁核派一直有個邏輯上的難題：
1. 台電很爛。
2. 台電管理的核電廠很安全，不會有問題。

Hot Spring

It's late May now, but Taiwan has been incredibly hot recently. Every day I get home from work, the temperature inside the apartment is close to 33 degrees Celsius. Even after opening windows and turning on fans for a few hours, it remains between 32.3 and 32.8 degrees Celsius. Although I'd love to save electricity for energy conservation and carbon reduction, I have no intention to lie awake and sweat all night. So, I'll put off showering until right before bed, then turn on the air conditioning, setting it to 28 degrees Celsius, and then I can sleep more comfortably. Otherwise, if I suffer from insomnia, it'll cause problems at work the next day and isn't good for my health. The resulting reduced productivity and wasted energy due to illness treatment would be worse than just running the AC for a bit.

現在是5月下旬，但臺灣最近實在是很熱，每天下班回到家，家裡的溫度接近攝氏33度，開窗開電風扇幾個小時後都還是維持在攝氏32.3~32.8度之間。雖然希望能省電來達到節能減碳，但是也不想整晚在床上冒汗睡不著覺，所以會拖到睡前才洗澡，洗完澡開冷氣，設定在攝氏28度，至少可以睡得較舒服，不然如果失眠，隔天上班會有問題的，對身體也不好，到時候生病治療造成的生產力下降及能源浪費，還不如開一下冷氣吧。

Hospital things

Today, as usual, I went to the family clinic to check my blood test report (twice a year) and pick up my chronic prescription (once every 8 weeks). I encountered a few really frustrating things.

1. Someone would constantly cough violently, take a break, and then continue coughing. It's fine to see a doctor for a persistent cough, but she'd pull down her mask every time she coughed.

2. Because the doctor was seeing patients so slowly, some people started asking the nurses if they could be seen first, and then one led to another, and another.

3. While waiting in line for medication, someone tried to cut in from the side. Didn't they see everyone else queuing up?

4. A Chinese person came to pick up a 3-month supply of medication to take back to China.

今天照慣例去家醫科看抽血檢查報告(每年2次)及慢性病拿慢性病處方簽(8週1次)，遇到了幾件令人很無奈的事情。

1. 有人不時就猛力咳嗽一頓，休息一下，之後又繼續咳。本來久咳不癒來看醫生沒問題，但是他是每次咳嗽就將口罩拉下來。
2. 因為醫師看診速度太慢，就有人開始跟護理師說希望能先處理他的，然後有一就有二，有二就有三。

3. 排隊等著領藥時，有人就從旁邊想要插隊進來。沒看到大家都在排隊嗎？

4. 一位中國人來拿3個月的藥帶回中國。

Lots of Rumor about Nuke by KMT+TPP

Just after happily celebrating Taiwan finally achieving a nuclear-free homeland with zero nuclear power, KMT and TPP legislators on May 20, 2025, immediately passed a referendum proposed by the TPP caucus: "Do you agree that the Third Nuclear Power Plant should continue operating after the competent authority confirms there are no safety concerns?" The vote is scheduled for August 23, 2025. (https://e-info.org.tw/node/241324)

Beyond this, pro-nuclear KMT and TPP parties and their supporters are spreading rumors everywhere, claiming that after the Third Nuclear Power Plant Unit 2 stops operating, thermal power generation will run at full capacity and Taiwan's air quality will immediately become terrible. This is utter nonsense. The Air quality monitoring by Taiwan Ministry of Environment clearly shows good air quality, and the photos I take every morning from a high floor of my building, showing the visibly clear air, haven't gotten worse. Furthermore, thermal power generation is primarily gas-fired, supplemented by coal. After the Third Nuclear Power Plant Unit 2 stops operating, these thermal power plants don't even need to run at full capacity because there's still enough electricity supply and sufficient reserve capacity. With the addition of renewable energy, Taiwan now (as of 2025) doesn't need to rely on thermal power to meet its electricity demands as much as it did years ago (e.g., 2016), when nuclear power plants were still operating and renewable energy accounted for a much smaller share. Many thermal power plants no longer need to run at full tilt. You can verify all of this yourself by checking Taipower's real-time electricity information (https://www.taipower.com.tw/2289/2363/2367/2368/10266/normalPost). Don't just believe baseless rumors. The Third Nuclear Power Plant Unit 2 only accounted for 3% of power generation before its shutdown, not 20% as some mistakenly believe.

Natural gas is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. When burned for heat or electricity, natural gas emits fewer toxic air pollutants, less CO2, and almost no PM (particulate matter) than other fossil fuels.(https://en.wikipedia.org/wiki/Natural_gas)

才剛剛很開心的慶祝臺灣終於核電歸零，實現非核家園，然後藍白立委就馬上於5/20/2025通過一個民眾黨團提案的「您是否同意第三核能發電廠經主管機關同意確認無安全疑慮後，繼續運轉？」公投法案，預計將在8/23/2025投票。(https://e-info.org.tw/node/241324)

除此之外，擁核的藍白政黨及其支持群眾開始到處造謠，說核三2號機停止運轉後，火力發電全開，臺灣空氣馬上變得很糟糕。根本就是胡說八道，明明空氣品質監測顯示空氣良好，而我每天早上出門前從大樓高層往遠處拍照、用來顯示視覺看到的空氣品質的照片也沒有變差。而火力發電也是以燃氣為主，燃煤為輔，在核三2號機停止運作後，由於發電量還夠用，也還有足夠備載用電，這些火力發電廠也不需要全力運轉。再加上再生能源的投入，現在(如2025)已經比幾年前核電廠還在運轉、再生能源佔比很少時(如2016年)還不需要靠火力發電來維持電力所需了，火力發電廠已經有許多不需要全力運轉。這些都可以自己去看台電的今日電力資訊(https://www.taipower.com.tw/2289/2363/2367/2368/10266/normalPost)，不要一天到晚相信造謠的言論。核三2號機在停機 前只佔了3%的發電量，不要自以為是20%好不好。

天然氣的主要成分是甲烷(CH4)，也可能含有一些較重的烴分子(如乙烷(C2H6)、丙烷(C3H8)和丁烷(C4H10))，以及一些酸性氣體(如二氧化碳和硫化氫)，部分氣田所產的天然氣還含有二硫化碳和羰基硫等有機硫。有機硫化物和硫化氫(H2S)這類常見的微量雜質，在大多數需要利用天然氣的情況下都要事先將其除去。看到分子式，就知道其燃燒排放主要是H2O及CO2，只要前端有確實做好脫硫，燃燒後的PM、NOx、SOx等污染排放會比燃煤或燃油減少非常多。

Discussion or not for a cross-disciplinary team

Since returning to work in my country, one of the most perplexing things is the prohibition of discussion, or being treated as a villain when the person tries to share her/his thoughts or discuss ideas with the team. When a team is formed to accomplish something together, especially a cross-disciplinary one, the essence should be discussion, communication of ideas, offering suggestions, converging diverging thoughts, and ultimately finding a common solution or working model from members with diverse backgrounds to develop the desired product or launch a research topic.

However, this approach has consistently been forbidden or scorned. The person is either accused of prying into secrets, criticized for overstepping boundaries, or told to keep things confidential and not let other members know. Even obvious mistakes shouldn't be pointed out; doing so is blamed as disrupting team harmony and gets you blacklisted.

回來工作後最令我困惑的事情之一，就是禁止討論，或是提出看法要和團隊討論的時候會被當作壞人。當組成一個團隊要一起做一件事情，特別是跨領域團隊，討論、溝通彼此想法、提出建議、收斂發散的不同想法，最後找到一個來自不同領域的共事成員的共同解決方案或做事模式， 一起將想要開發的產品做出來或開展一個研究主題。但是這樣的方式一直被禁止或嫌棄，要嘛被戴上窺探機密的帽子，或是被指責踩線，不然就是被要求要保密而不應該讓其他成員知道，甚至連明顯的錯誤都不應該提出，講了就是破壞團隊和諧，然後成為黑名單成員。

Nuclear-Free Taiwan starts from 20250517 22:10

After 40 years of effort, the nuclear-free country was finally achieved on May 17, 2025, at 10:10 PM in Taiwan, and my heart is filled with joy. Coming from the era when anti-nuclear power was synonymous with anti-dictatorship, I recall the fear of standing in the front row facing riot police with other students in front of Taipower on the day before the anti-nuclear demonstration (May 5, 1991). The sights and sounds I witnessed day and night at the entrance of Taipower shattered the perfect facade of the KMT's party-state rule that had been built in my mind. Yes, it was that day that I, who had been very obedient and trusting of the government, finally woke up.

努力了超過40年的非核家園終於在20250517 22:10達成，從反核就是反獨裁的年代一路走來，我內心喜悅。在反核示威遊行的前一天(19910504)，和其他學生在台電門口站在第一排面對鎮暴警察的害怕，那一夜夜宿台電門口的抗議活動中的所見所聞，戳破了國民黨黨國統治在我心中塑造的完美假象。是的，就是那一天，很乖很聽話相信政府的我醒了。

OKR vs. KPI

今天聽 podcast (https://podcasts.apple.com/tw/podcast/id1586296758?i=1000682466626)，在介紹這本書 "主管必看！最強KPI管理術：活用10大步驟、53張圖表，績效輕鬆達標" (https://www.books.com.tw/products/0011003639)，裡面提到 OKR (Objectives and Key Results)及 KPI (Key Performance Indicators)，也提到該擺脫「不明所以的KPI」。

KPI管理指的是，所有相關人士都持續分享、實施並改善以下3點：
　　①明確目前事業最重要的步驟（Critical Success Factor, CSF）
　　②這項步驟該執行到什麼程度（Key Performance Indicator, KPI）
　　③事業計畫能夠達成嗎？（Key Goal Indicator, KGI）

或許有空該來閱讀看看，不一定是用在工作，或許自己的人生也應該要想一下自己的 OKR 及 KPI 為何。

I listened to a podcast (https://podcasts.apple.com/tw/podcast/id1586296758?i=1000682466626) today, which introduced the book "A Must-Read for Managers! The Most Powerful KPI Management Technique: Use 10 Steps and 53 Charts to Easily Achieve Performance Targets" (https://www.books.com.tw/products/0011003639). It mentioned how to manage a company with OKR (Objectives and Key Results) and KPI (Key Performance Indicators), and that we should get rid of "unclear KPIs."

KPI management means that all stakeholders continuously share, implement and improve the following three points:

① Identify the most important steps in your current career (Critical Success Factor, CSF)

②To what extent should this step be executed (Key Performance Indicator, KPI)

③Can the business plan be achieved? (Key Goal Indicator, KGI)

Maybe I should read it sometime. I think that I don't need to limit the application of OKR and KPI to work only, I might set up my own OKR and KPI for my life.

----------------------
When I searched OKR vs. KPI in google, AI overview provided following information: 
OKRs (Objectives and Key Results) are a goal-setting framework, while KPIs (Key Performance Indicators) are metrics used to track progress towards those goals. OKRs focus on defining ambitious goals and then measuring progress towards them, while KPIs are focused on specific, quantifiable measures of success.

Objectives and Key Results (OKRs):
What they are: OKRs are a goal-setting framework that helps organizations define ambitious targets and track their progress towards achieving them.

Structure: OKRs consist of two parts:Objective: A qualitative, aspirational goal that describes what you want to achieve.

Key Results: A set of quantifiable metrics that measure progress towards the objective.

Purpose: OKRs are used to: 

Set ambitious, measurable, and time-bound goals.

Align teams and individuals around shared goals.
Track progress and make adjustments as needed.

Key Performance Indicators (KPIs):
What they are: KPIs are specific, quantifiable measures of success that allow you to track organizational performance.

Purpose: KPIs are used to:

Track progress towards specific goals.
Identify areas for improvement.
Make data-driven decisions.

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.
