虎虎吃短信 vs Bio

「虎虎吃短信」使用Apple官方 Core ML 机器学习框架在设备端离线过滤垃圾短信，能准确的通过语义识别垃圾短信，不需要手动配置任何过滤规则，开箱即用。 # 隐私 我们非常在意您的隐私，并且通过行动（而不只是口头承诺）来保证这一点：虎虎吃短信是一个非常少见的完全离线的应用，甚至都不会请求网络权限（直到您第一次主动向我们举报垃圾短信）。我们依靠广大的用户群体主动向我们举报垃圾短信来建立机器学习的样本库。 # 集体智慧 虎虎吃短信使用基于统计学的机器学习算法从几十万条各类短信样本中学习而成。无需用户配置任何关键词，它通过识别一个短信的语义特征，自己就可以精准的判断收到的短信是正常短信、公益短信还是广告骚扰短信等等。 如果虎虎有判断失误的时候，大家可以在 App 里面投喂新的短信样本帮助虎虎进化，喂养越多虎虎越聪明。 # 我为什么要做「虎虎吃短信」？ 我曾深受垃圾短信的困扰，直到 iOS 11 发布了短信过滤的接口。作为一个涉足数据领域的工程师，我导出了几年里收到过的几万条短信，使用机器学习训练了一个垃圾短信的识别模型，就有了这个 App 的雏形。在后续的开发中很多热心的用户又投喂了几十万条短信样本，教会了虎虎识别更多更广阔的场景。 ** 隐私条款：虎虎会收集哪些信息？** 「虎虎吃短信」不会收集您的任何信息，更不会上传您的短信内容，如果您足够细心就会发现虎虎都不会请求网络权限，完全离线运行。 如果您自愿向虎虎提交短信样本，那么会收集脱敏后的短信文本以及一个您标注是否是垃圾短信的数字，仅此两项数据。 关于订阅: 使用条款: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 隐私协议: https://www.redianzi.cn/api/private/privacy_tigereat 技术与支持: 如若您在使用过程中遇到任何问题，先不要着急，您可以通过以下方式联系到我们: 邮箱1: developer@redianzi.cn 邮箱2: ray@redianzi.cn

Bio-Calculator brings everyday life science calculations to your iPhone and iPad. Designed for researchers, students, and laboratory professionals, it covers solution preparation, nucleic acid and protein conversions, manual counting, and cell seeding calculations. SEE THE CALCULATION Supported calculators show the formula and substituted values below the result. Copy the calculation steps for your lab notes, check your method, or use them when preparing a report. MANUAL COUNTING A dedicated Count tab supports multiple counters, custom labels, increment and decrement controls, and counting history. Turn sound and haptic feedback on or off, and transfer counting data to CFU or cell density calculations to avoid entering it again. CELL DENSITY AND SEEDING Calculate cell density and viability from your hemocytometer counting area, number of squares counted, live and dead cell counts, and dilution factor. Add the suspension volume to calculate the total viable cell count. Use your seeding target to calculate the required cell suspension and medium volumes. Enter the overall dilution factor directly, or calculate it from the factor per step and number of dilution steps. NUCLEIC ACIDS AND PROTEINS • Convert mass, amount in moles, and concentration for DNA, RNA, and proteins. • Calculate nucleic acid sequence molecular weight and GC content. • Convert OD260 absorbance readings to nucleic acid concentration. • Calculate vector and insert amounts for ligation reactions. • Estimate DNA and mRNA coding capacity. SOLUTIONS AND UNIT CONVERSIONS • Molarity, mass concentration, and solution dilution calculations. • Molecular weight from a chemical formula. • Relative centrifugal force (RCF) and rotational speed (RPM) conversions. • Temperature conversions and a scientific calculator. MICROBIOLOGY AND VIROLOGY Tools for CFU calculations, colony-counting dilution planning, bacterial growth and doubling time, and TCID50 calculations. LAB SOLUTION RECIPES Find preparation methods for buffers and stock solutions such as PBS, TAE, TBE, Tris, and EDTA, with relevant sterilization, storage, and handling notes. Available in English, Simplified Chinese, and Traditional Chinese. Some features require an in-app purchase. For research and educational calculations. Check input units, counting chamber specifications, and experimental conditions before using results. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
