Spy x family chap 4

Alright, so I'm writing my thesis. This topic is about a decision making matrix, to make decisions using n criteria and n weights for m amount of alternatives.
snippet from paper
Now I don't understand the formulas from PIS and NIS. Especially the v^+_1, v^+_2, etc.
What does the + or - mean above v? I know that v a weighted normalised matrix is from all of the alternatives and all of the criteria.
Some more background information:

I hope you can help me! Thanks in advance and let me know if I can assist in any way!

This story is back from 6th grade, there was a guy in my class(let us call him Jacob) who used to have a crush on me I didn't even know him before but in the seventh grade I came to know him got a tini tiny crush on him and told my best friend about it she was like "yeah good finally someone you can gush about all the time" then a few months later my crushes friends told me that he had a crush on me I didn't know what to do so I pretended that I didn't hear it and after that, a few weeks went by my crush on him was getting removed as I found someone else I liked(my current bf) and not to mention that the guy I used to have a crush on was one of my family friends. So I decided to tell my best friend about the new guys I started to like a little and she was like "Gurl I know that you are obsessed with Jacob are you sure? cus I see him staring at you from across the class". I was like yea I know that I had a crush on him for a while but now it is kinda going away. a month later my new crush went away to his native place for a while. I know this sound complicated but I kinda started to have a crush on Jacob again. so I decided to confess to him but I didn't do it right away this was the time around valentines Day so I decided to do it then but I feel ill for 4 days so after my cold a fever went away I was back to school and I realized that a BFF had gotten close to Jacob I thought that it is ok and all and my stupid ass didn't even confess to Jacob my BFF told me that she wanted to talk to jacob alone and I approved the place they went to talk was a very silent place there was no notice a few days later it was my BFFs birthday which is 3 days before mine Jacob wished her but not me then i realized that something fishy was going on i confessed my BFF then started acting weird then i realized the jacob was flirting with my friends i immediately confronted him then I shifted school now it has been 9 years I'm going to his house for dinner:!!!

Been evaluating DMARC recently, and I couldn't find much information to help guide me when comparing options. So I tried to write down my thoughts in a way I would have found useful. I hope someone on here gets a bit of value out of it.
A few observations is that there is a huge disparity between bottom range vendors and top range vendors in terms of price, and that there is a corresponding disparity in terms of tool functionality and Trust-center maturity. Top tier vendors offer some cool functions, but the increase in price was hardly worth it.
Common DMARC vendor problems
Common problems among nearly all DMARC vendors we spoke to (with 1 exception) was that they all had a hard time giving us a fixed quote, claiming that they needed to run a PoC/Trial to analyze our volumes before being able to quote us. A few would provide gross estimates for us. I got a bit grossed out, because it felt like the sales reps we met with were trying to gauge how much money they'd be leaving on the table.
Bottom Tier DMARC vendor problems
The bottom tier were sketchy in terms of where support is located, where data is processed (issue especially if we collect Forensic reports) and had a difficult time answering questions on the robustness and maturity of their organizational/technical controls for whatever certifications they held. They also provided low-usability UI:s and underwhelming project management features.
One of the vendors even suggested we spin up 2 instances of their platform to manage active/inactive domains separately. I assume sales person was either a) incompetent or b) thought we had just jumped off the bus from Jokkmokk or c) the tool was horrendous.
Another consideration was that these vendors were mostly in start-up mode, and really pushed their logo-slides, indicating to me that they are desperately accumulating corporate value to become attractive acquisition targets. God forbid they'd be purchased by like DarkTrace or something.
I did a bit of quick and dirty math, and couldn't see how they were running sustainable business models. When they described their headcounts and I looked at the revenue generated with an average across their entire "we have this many customers" slide. Especially since a few of the logos these guys said were 'customers' are actually using their freemium/trial to monitor (checked with contacts at company's who were part of the logo-slides.).
These vendors cost next to nothing, but introduce a level of risk I was not happy with.
Top Tier DMARC Vendor problems
3 of the vendors we looked at fit into this category, and the prices were absolutely outrageous. As in +30x higher prices. Than the other vendors. 2 of these were more forthcoming about price estimates, and the last one did the thing where the sales rep was really shady about the pricing so we finally had enough (I found their price list through google dorks and nearly puked).
However, the 2 vendors who were more forthcoming about their prices advised us that there is a mandatory Managed Service tacked onto the DMARC tool. The managed service sounded nice (bi-weekly/monthly project calls with a consultant from their side, effectively brining our time investment down by from ~6-8h / week to ~1-4h / week, which is helpful due to backlog). But we would be unable to unsubscribe from the managed service even after achieving p=reject and just monitoring.
The vendor who's prices nearly made me puke literally had 1 unique selling point compared to peers. The ability to generate DKIM keys through their console. Helpful, sure. But it absolutely does not merit a 2x higher price than the other 2 Top Tiers. The issue I have here is that this was the vendor pushed by Microsoft, and it really got under my skin that the sales rep almost took it for granted that the business was theirs because of the recommendation by MSFT. It made me wonder how many deals these guys get for outrageous price points by buyers who don't know any better.
These vendors cost a bunch, but offer the level of risk I am OK with introducing
What did we end up doing?
One of the vendors who didn't fit into either Top Tier or Low Tier fulfilled our criteria;

1. Mature trust-center backed by good contracts, DPA:s ISO-certs and SOC-II etc. Sales rep and Engineer could speak towards various elements and were happy to make introductions to their CISO:s direct reports for more information.
2. Price point was in-between Top tier & Bottom Tier.
3. Price transparency and Predictability (They could provide prices based on # active domains + number of employees, irrespective of email volumes & sending services)
4. Managed service portion could be removed upon renewal (once every 12 months) and the price effectively goes down by 50%.
5. The sales rep was slightly less sleazy, but maybe that was because their licensing model was simpler? He was also transparent when we asked about recent negative feedback about their support.
6. UI is decent & Integrated project management section so that tasks created in other sections of the console are populated into the project management time-line and assigned to an owner.

Notes;

1. I don't want to break any policy here. So won't post a link to the price-list I found via dorks. I found it on a publicly facing governmental digital market place, published by one of the vendor's partners. Example:
   1. 3-10 Domains + <5 Sending Services scales from £17.5K / year up to 3-10 Domains + <27 Sending services for £100K / Year. And god help you if you have +50 domains.
2. Don't want to mention which vendor we went with in the end. But we got 25 Domains + Unlimited volume + unlimited sending services for ~ €12K / year.
   1. As a comparison this is 10x the price of the Low-tier vendors, and 35% of the price of the most expensive vendor (when accounting for our number of sending sources, email volume and domains)
   2. Year 1 we added on Manage Services to help with our backlog, which we plan on cutting away once p=reject can be safely activated (expected time frame ~6 months -- Which realistically means ~8 months). At this point our annual bill goes down from €18K to €12K / Year.
3. A key consideration that I found tricky before finding the vendor we went with, was trying to forecast expected email volumes since the company is planning on entering new markets, with big marketing pushes. We could have woken up one day and gotten a "true-up" call with up-to a 6x license price increase if our outbound volumes exceeded 2.5million emails. (I don't see that happening anytime soon, but I'd hate to forget about this as the company grows).
4. Getting approval for the spend was done together with marketing, and we split it 50/50. We basically asked our CMO-lite what would happen if their marketing emails went to junk-folders or were rejected outright because one of their marketing services was unaccounted for.
   1. Convo went something like:
      1. "What's your worst-case projection for this initiative?"
      2. "It's x% of target"
      3. "Okey, does that worst-case projection account for if your email marketing ends up in junk folders?"
      4. "Ye... erhh.. end up in junk folders...?"
      5. (Marketing now has a vested interest in being open about the crap they use/want to get, and CMO-lite has raised this twice with her team so far).

Sorry for any spelling/grammar issues, guys. English =/= first language. Some of the information here could be inconsistent between territories/markets. Hope someone finds it helpful.

At the time of death: [M21,South East Asian descent]
Non smoker, non alcohol drinker, athletic lifestyle
Hello. I'm just asking for closure's sake.
My late uncle passed in 2001. He was born in 1980. He was 21 years old. From what my dad(the eldest son, his big brother) told me, my uncle Z had a persistent cough that would not go away. Several hospital visits later, he was eventually diagnosed with Stage 2 Lung Cancer. All the family was told was that it was malignant. He was doing fine and he did all of his chemos except he missed one session. His last. Then shortly afterwards he passed.

1. Can lung cancer just pop up like that? Back then, nobody in the family smoked. He didn't smoke.
   
2. Do you think if he didn't miss that one session - we could've had him any longer?
   

For the second case also a late family member
My late granduncle(My uncle Z's Uncle) (Age at time of death: Early 60's approx) (Year of death: 2022 Sept)
Non smoker, non alcohol drinker
He had been taking medication for abdominal issues and he went to the ER because he felt pain around his area. Less than a day later, left the ER with a stage 4 colon cancer diagnosis which had already spread to his heart. He hadn't even gone through choosing whether to do chemo as he passed at home less than 5 days later.
Just. Ultimate question is:
I just want to know is there any possibility that they had a painless death? Or at the very least with minimal pain?
Is there some tests available to see if like my family just generally has a genetic predisposition to cancer?
Thank you.

Earlier my thermostat (Nest) wasn't responding to Home commands. Logged in to Hoobs, and it was very sluggish just to load in browser. I restarted, and still can't change the temperature from Home app, or inside Hoobs.
I cannot control myQ garage, Govee light, or the stated Nest thermostat from the Home app or in Hoobs. They all work within their individual apps. However, my Roomba and Dyson connections are working as normal.
Trying to update the system software, and this is how it starts out

Anyone have any idea as to what the issue could be? Nothing in my home has changed.

Hello, I was a bit confused with this problem on Lagrangian multipliers.
I have f(x,y,z) set up as x^2 + y^2 + z^2 for the origin, and g(x,y,z) as xy - z^2 +4. I was able to solve for lambda and determine that y = x and y = -x as possiblities, but when plugging in for z, z cancels out as -1 = lambda, so I'm not really sure how to proceed and determine z, or if I should use a different approach.
Any insight would be appreciated!
