The Piper PA-14 Family Cruiser is an American -built small touring aircraft of the late 1940s. Piper Aircraft had built the PA-12 Super Cruiser three-seat touring aircraft between early 1946 and March 1948.

2018年7月13日 · 查阅了很多资料最终发现原来不只PB3、PB4，还有PA13-15这五个引脚不是普通的IO口，用作JTAG/SWD 仿真器 的调试接口，引脚描述如《STM32参考手册》中所示： 这些引脚只有重定义功能后才能作为普通的IO口使用，所以我们需要对这些引脚进行配置的时候开启AFIO复用时钟。 文章浏览阅读3.1w次，点赞50次，收藏212次。 最近使用stm32f103c8t6进行按键上拉输入配置的时候，发现一样的电路，只是将代码PA1-PA4换做PB3-PB6接口，怎么也无法得出 …

2021年7月29日 · Here, we show that products of the PA14 reb cluster associate with R-bodies and control stochastic expression of R-body structural genes. PA14 expresses reb genes during colonization of plant...

2011年12月22日 · Here, we show that the virulent strain PA14 has an acquired mutation in the ladS gene. This mutation has a deleterious impact on biofilm, while it results in elevated type III secretion system (T3SS) activity and increased cytotoxicity towards mammalian cells. These phenotypes can be reverted by repairing the ladS mutation on the PA14 genome.

在大约 5,000 种菌株中，pao1 和 pa14 是常见的实验室参考菌株，分别模拟中度和超强毒性表型。pao1 和 pa14 在促进新型药物靶标的发现、新型疗法的测试以及提供细菌的关键基因组信息方面发挥了重要作用。

2022年10月13日 · Pseudomonas aeruginosa is a ubiquitous, motile, gram-negative bacterium that has been recently identified as a multi-drug resistant pathogen in critical need of novel therapeutics. Of the approximately 5,000 strains, PAO1 and PA14 are common laboratory reference strains, modeling moderately and hyper-virulent phenotypes, respectively.

This 1948 Piper PA-14 Family Cruiser is for sale for $125,000. It has 11,117 hours on the airframe and the engine has 749 hours on it.

2023年2月9日 · 详细介绍了如何将pa13和pa14从swdio和swclk转换为普通io口的步骤，并警告这样操作后会阻止程序下载，需通过改变boot0状态来恢复下载功能。 建议避免使用PA13和PA14作为IO口。

PA14 is a clinical isolate obtained from a burn patient that displays pathogenicity in a variety of genetically tractable model hosts and mice (2 3 4 5 10). To facilitate study of P. aeruginosa we have created an extensive library of PA14 transposon insertion mutants and identified the transposon insertion site in each mutant( 17 ).

2023年10月7日 · PB14和PB15：这对引脚是USB_OTG_HS的D-和D+数据线。 PA9和PA10：这对引脚也可以用作USB_OTG_FS的D-和D+数据线，但需要将相应的引脚复用功能设置为USB主机模式。 除了以上提到的引脚，还需要注意以下几点： USB_OTG_FS和USB_OTG_HS是两个不同的USB控制器，FS代表全速（Full Speed），HS代表高速（High Speed）。 USB_OTG_FS可以支持全速和低速USB设备，而USB_OTG_HS则支持全速、低速和高速USB设备。 如果需要使 …
