6000 mAh silicon negative battery! Xiaomi 15Pro upgrade leaked again 6000 mAh silicon negative battery! Xiaomi 15Pro upgrade leaked again Jul 24, 2024 pm 12:45 PM

According to news on July 23, blogger Digital Chat Station broke the news that the battery capacity of Xiaomi 15 Pro has been increased to 6000mAh and supports 90W wired flash charging. This will be the Pro model with the largest battery in Xiaomi’s digital series. Digital Chat Station previously revealed that the battery of Xiaomi 15Pro has ultra-high energy density and the silicon content is much higher than that of competing products. After silicon-based batteries are tested on a large scale in 2023, second-generation silicon anode batteries have been identified as the future development direction of the industry. This year will usher in the peak of direct competition. 1. The theoretical gram capacity of silicon can reach 4200mAh/g, which is more than 10 times the gram capacity of graphite (the theoretical gram capacity of graphite is 372mAh/g). For the negative electrode, the capacity when the lithium ion insertion amount reaches the maximum is the theoretical gram capacity, which means that under the same weight

How to access JSONNode's JSON fields, arrays and nested objects in Java? How to access JSONNode's JSON fields, arrays and nested objects in Java? Aug 30, 2023 pm 11:05 PM

A JsonNode is Jackson's JSON tree model that can read JSON into JsonNode instances and write JsonNode into JSON. We can use Jackson to read JSON into a JsonNode by creating an ObjectMapper instance and calling the readValue() method. We can access fields, arrays or nested objects using the get() method of the JsonNode class. We can use the asText() method to return a valid string representation and convert the node's value to Javaint using the asInt() method of the JsonNode class. In the example below we can access Json

Access metadata of various audio and video files using Python Access metadata of various audio and video files using Python Sep 05, 2023 am 11:41 AM

We can access the metadata of audio files using Mutagen and the eyeD3 module in Python. For video metadata we can use movies and the OpenCV library in Python. Metadata is data that provides information about other data, such as audio and video data. Metadata for audio and video files includes file format, file resolution, file size, duration, bitrate, etc. By accessing this metadata, we can manage media more efficiently and analyze the metadata to obtain some useful information. In this article, we will take a look at some of the libraries or modules provided by Python for accessing metadata of audio and video files. Access audio metadata Some libraries for accessing audio file metadata are - using mutagenesis

MIT's latest masterpiece: using GPT-3.5 to solve the problem of time series anomaly detection MIT's latest masterpiece: using GPT-3.5 to solve the problem of time series anomaly detection Jun 08, 2024 pm 06:09 PM

Today I would like to introduce to you an article published by MIT last week, using GPT-3.5-turbo to solve the problem of time series anomaly detection, and initially verifying the effectiveness of LLM in time series anomaly detection. There is no finetune in the whole process, and GPT-3.5-turbo is used directly for anomaly detection. The core of this article is how to convert time series into input that can be recognized by GPT-3.5-turbo, and how to design prompts or pipelines to let LLM solve the anomaly detection task. Let me introduce this work to you in detail. Image paper title: Largelanguagemodelscanbezero-shotanomalydete
