"迈向语言隐写术：一项系统研究探讨了在计算机科学领域中一个独特且具有挑战性的主题——将机器可读的数据编码成看似无害的自然语言文本，即语言隐写术（Linguistic Steganography）。这项技术旨在提供一种在第三方监控下秘密传递信息的安全手段，通过利用自然语言的复杂性和人类的易接受性来隐藏信息。 当前，关于语言隐写术的系统性文献并不多见，这方面的研究存在一定的空白。本报告由Richard Bergmair撰写，对这一领域进行了详尽的梳理和填补。报告首先介绍了背景知识，涵盖了隐写术的基本概念和原理，以及自然语言处理（NLP）的最新进展。作者强调了语言隐写系统设计的重要性，包括如何确保信息的嵌入和提取，以及如何使得文本看起来毫无破绽。 报告详细列举了已有的语言隐写系统，包括它们所依赖的技术、工作原理和实现细节。这些系统旨在达到的目标，如信息传输的可靠性、隐蔽性以及在不同语言环境下的适用性，都被逐一阐述。设计考虑因素和评估标准也得到了深入讨论，以确保系统既能满足功能需求，又能抵抗可能的检测和破解尝试。 此外，报告还提出了未来的研究方向，探讨了潜在的问题和挑战，如如何提高嵌入效率、如何增强系统的抗干扰能力，以及如何在保证信息安全性的同时，尽可能保持文本的自然流畅度。语言隐写术的边界和可能的应用场景，如在密码学、信息安全和隐秘通信中的应用，也是报告关注的重点。 这份报告不仅为语言隐写术的研究者提供了宝贵的参考资料，也为那些希望利用自然语言进行隐秘通信的人提供了实用的设计原则和技术指南。随着技术的发展和安全需求的日益增长，语言隐写术将在未来的信息传输和保护策略中发挥重要作用。"

翻译成中文In dynamical systems theory, a stable manifold is a set of points in phase space that converges towards a stable equilibrium point or limit cycle. More specifically, it is a set of initial conditions for which the system will converge towards the stable equilibrium or limit cycle. The stable manifold can be thought of as a geometric structure that characterizes the behavior of the system near the equilibrium or limit cycle. In the context of the HH neuron model discussed in the referenced article, the stable manifold is the set of initial conditions for which the system will converge towards the stable resting state of the neuron. This is because the stable resting state is the only stable equilibrium point of the system. Trajectories that start to the left of the stable manifold will quickly converge towards the stable resting state, while trajectories that start to the right of the stable manifold will diverge from the resting state and eventually converge towards the unstable equilibrium point. Overall, the stable manifold is a fundamental concept in dynamical systems theory and plays an important role in understanding the behavior of nonlinear systems such as the HH neuron model.

Create a function pixel_flip(lst, orig_lst, budget, results, i=0) that uses recursion to generate all possible new unique images from the input orig_lst, following these rules: • The input lst is the current list being processed. Initially, this will be the same as orig_lst which is the original flattened image. • The input budget represents the number of pixels that can still be flipped. When the budget reaches 0, no more pixels can be flipped. • The input results is a list of resulting flattened images with flipped pixels. Initially, this will be an empty list. • The input i represents the index of the pixel being processed, by default set to 0, which is used to drive the recursive function towards its base case (i.e., initially starting from i=0). At termination of the function, the argument results should contain all possibilities of the input orig_lst by only flipping pixels from 0 to 1 under both the budget and the adjacency constraints. fill code at #TODO def pixel_flip(lst: list[int], orig_lst: list[int], budget: int, results: list, i: int = 0) -> None: """ Uses recursion to generate all possibilities of flipped arrays where a pixel was a 0 and there was an adjacent pixel with the value of 1. :param lst: 1D list of integers representing a flattened image . :param orig_lst: 1D list of integers representing the original flattened image. :param budget: Integer representing the number of pixels that can be flipped . :param results: List of 1D lists of integers representing all possibilities of flipped arrays， initially empty. :param i: Integer representing the index of the pixel in question. :return: None.
