Sao Kim bắn tim Sao Hỏa tập 9: Quý bị bắt gặp vào phòng gái ngành Trinh

Theo công ty nghiên cứu Counterpoint, thị trường điện thoại thông minh cũng đang được cải thiện khi doanh số smartphone giảm 8% trong 3 tháng gần nhất so với mức giảm 14% của quý I/2023.

“Nhu cầu đang phục hồi nhưng rất chậm”, Woohyun Kim, giám đốc tài chính SK Hynix cho biết trong cuộc họp báo cáo doanh thu của công ty. “Sự cải thiện về các lô hàng PC chủ yếu đến từ những chương trình khuyến mãi và mẫu máy cấp thấp, điều này có nghĩa nó có tác động hạn chế với việc phục hồi nhu cầu chip nói chung”.

Mặc dù nhu cầu về chip hỗ trợ AI sinh tạo tăng lên nhanh chóng kể từ khi ChatGPT của OpenAI ra mắt vào cuối năm 2022, lĩnh vực này vẫn chỉ chiếm một phần nhỏ trong tổng nhu cầu chip, thậm chí còn làm giảm chi tiêu của một số công ty cho máy chủ do họ chuyển hướng đầu tư vào AI.

Ngoài ra, sự phục hồi chậm chạp ở Trung Quốc, thị trường chip lớn nhất thế giới, cũng làm giảm triển vọng chung toàn ngành.

Cả Samsung và SK Hynix chung nhận định việc Trung Quốc mở cửa trở lại không đáp ứng kỳ vọng về tốc độ hồi sinh thị trường smartphone, đồng thời nói rằng họ đang mở rộng cắt giảm sản xuất chip nhớ NAND vốn được sử dụng rộng rãi trong các thiết bị di động cầm tay lưu trữ dữ liệu kỹ thuật số.

Tương tự, Texas Instruments (TI), nhà sản xuất chip có mối quan hệ mật thiết với thị trường Trung Quốc, dự báo doanh thu và lợi nhuận quý II/2023I sẽ dưới kỳ vọng của phố Wall do nhu cầu phục hồi chậm buộc đối tác phải huỷ đơn hàng.

Theo Logan Purk, chuyên gia phân tích tại công ty đầu tư Edward Jones, đến cuối năm tài chính 2022, Trung Quốc chiếm “một nửa doanh số bán hàng của TI”.

AI là điểm sáng

Các nhà sản xuất thiết bị đúc chip như KLA Corp và Lam Research là những cái tên hưởng “quả ngọt” từ sự bùng nổ AI. Cả hai công ty đều dự báo doanh thu quý cao hơn ước tính phố Wall.

“Các máy chủ AI tiên tiến có hiệu suất cao hơn đáng kể so với máy chủ truyền thống. Với mỗi 1% gia tăng của máy chủ và trung tâm dữ liệu AI sẽ thúc đẩy khoản đầu tư bổ sung từ 1 cho đến 1,5 tỷ USD”, CEO Tim Archer tại Lam Research nói.

Các nhà sản xuất chip cũng đang tăng cường sản xuất vi xử lý cao cấp dùng trong hỗ trợ chip AI. 

SK Hynix cho biết nhu cầu về bộ nhớ máy chủ AI đã tăng gấp đôi trong quý II/2023 sao với ba tháng đầu năm. Trung bình, giá các chip DRAM - bộ phận chứa thông tin của các ứng dụng chạy trên hệ thống, đã tăng lên so với quý I/2023.

Theo TrendForce, nhà sản xuất Hàn Quốc cũng đang là công ty dẫn đầu thị trường DRAM băng thông cao (HBM) dùng trong AI sinh tạo, với 50% thị phần của năm 2022, xếp sau đó là 40% của Samsung và 10% từ Micron.

WAYS TO IMPROVE YOUR MEMORY

A good memory is often seen as something that comes naturally, and a bad memory as something that cannot be changed, but actually (31)______ is a lot that you can do to improve your memory.

We all remember the things we are interested in and forget the ones that bore us. This no doubt explains the reason (32)______ schoolboys remember football results effortlessly but struggle with dates from their history lessons! Take an active interest in what you want to remember, and focus on it (33)______. One way to ̳make‘ yourself more interested is to ask questions — the more the better!

Physical exercise is also important for your memory, because it increases your heart (34)______ and sends more oxygen to your brain, and that makes your memory work better. Exercise also reduces stress, which is very bad for the memory.

The old saying that ―eating fish makes you brainy‖ may be true after all. Scientists have discovered that the fats (35)______ in fish like tuna, sardines and salmon — as well as in olive oil — help to improve the memory.

It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these beverages soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called "energy drinks." These beverages have the specific aim of giving tired consumers more energy.

One example of a popular energy drink is Red Bull. The company that puts out this beverage has stated in interviews that Red Bull is not a thirst quencher. Nor is it meant to be a fluid replacement drink for athletes.

Instead, the beverage is meant to revitalize a tired consumer's body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their beverages. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these beverages all seem like a sure bet to give a person energy.

Health professionals are not so sure, though. For one thing, there is not enough evidence to show that all of the vitamins added to energy drinks actually raise a person's energy level. Another problem is that there are so many things in the beverages. Nobody knows for sure how all of the ingredients in energy drinks work together.

Dr. Brent Bauer, one of the directors at the Mayo Clinic in the US, cautions people about believing all the claims energy drinks make. He says, ―It is plausible if you put all these things together, you will get a good result.‖ However, Dr. Bauer adds the mix of ingredients could also have a negative impact on the body. ―We just don't know at this point,‖ he says.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

What is ̳extreme‘ weather? Why are people talking about it these days? ̳Extreme‘ weather is an unusual weather event such as rainfall, a drought or a heat wave in the wrong place or at the wrong time. In theory, they are very rare. But these days, our TV screens are constantly showing such extreme weather events. Take just three news stories from 2010: 28 centimetres of rain fell on Rio de Janeiro in 24 hours, Nashville, USA, had 33 centimetres of rain in two days and there was record rainfall in Pakistan.

The effects of this kind of rainfall are dramatic and lethal. In Rio de Janeiro, landslides followed, burying hundreds of people. In Pakistan, the floods affected 20 million people. Meanwhile, other parts of the world suffer devastating droughts. Australia, Russia and East Africa have been hit in the last ten years. And then there are unexpected heat waves, such as in 2003 in Europe. That summer, 35,000 deaths were said to be heat-related.

So, what is happening to our weather? Are these extreme events part of a natural cycle? Or are they caused by human activity and its effects on the Earth‘s climate? Peter Miller says it‘s probably a mixture of both of these things. On the one hand, the most important influences on weather events are natural cycles in the climate. Two of the most famous weather cycles, El Niño and La Niña, originate in the Pacific Ocean. The heat from the warm ocean rises high into the atmosphere and affects weather all around the world. On the other hand, the temperature of the Earth‘s oceans is slowly but steadily going up. And this is a result of human activity. We are producing greenhouse gases that trap heat in the Earth‘s atmosphere. This heat warms up the atmosphere, land and oceans. Warmer oceans produce more water vapour – think of heating a pan of water in your kitchen. Turn up the heat, it produces steam more quickly. Satellite data tells us that the water vapour in the atmosphere has gone up by four percent in 25 years. This warm, wet air turns into the rain, storms, hurricanes and typhoons that we are increasingly experiencing. Climate scientist, Michael Oppenheimer, says that we need to face the reality of climate change. And we also need to act now to save lives and money in the future.
