一呼百应

一 | New Delhi, Oct 13 (UNI) Congress leader Shashi Tharoor on Thursday said there were systematic flaws in the Congress presidential election process, even as he clarified he was not suggesting it was intentional.

The Thiruvananthapuram MP also indicated at differential treatment between him and Mallikarjun Kharge, who is being seen as the choice or the party leadership. Congress has maintained the party is not backing any candidate officially.

Addressing a press conference here, Tharoor said while he is not pointing fingers at Central Election Authority Chairman Madhusudan Mistry, there are flaws in the system.

"I am not saying anything against Mr. Mistry, there are some flaws in the systems which we all know. There have not been elections for 22 years..." said Tharoor.

He said there were discrepancies in the lists of voters provided.

"One list was given earlier, another list was given on Wednesday.... Some names were different in the lists, for some names, there was no phone number," he said.

"I am not saying it's being done intentionally. There have not been elections in our party for a long time. So there are issues. I know Mr. Mistry and his team are trying to hold free and fair elections. We are not complaining against them but there ar problems with the system," he said.

"That is why I used open mediums to take my message across. I am not sure I will be able to reach everyone before 17th."

He also pointed at differential treatment to candidates.

"Another issue is what some leaders did, that is why I said there is no level playing field. At a lot of places, big leaders, PCC chiefs welcome Kharge ji, call people for meetings. This happened for only one candidate, not for me," he said.

"Many times when I went to some PCC, the PCC chief became busy on the day...I am not complaining, but do you not see a difference in treatment?"

Election will be held on October 17, counting will be held on October 19 and results will be declared.

UNI AO BAV。杭州造出了可量产“超级冰箱”。

二 | 2025年8月，杭州白马湖实验室造出了一台“超级冰箱”。在零下268.95摄氏度的液氦温区，这台脉管制冷机的制冷量达到了1.8到2瓦，降温时间稳定在45分钟左右。这个温度，离绝对零度（零下273.15摄氏度）只差4.2开尔文，被称为现代前沿物理世界的“门槛温度”。今年5月，记者曾专访“超级冰箱”研发团队。

三 | 这是国内首台采用单一气库技术路线、实现1.5瓦以上制冷量的脉管制冷机，近日，正式通过量产验证。怎么理解这台“超级冰箱”的原理？白马湖实验室氢能储运团队独立首席研究员方凯解释：气体被压缩的时候，会放热。

四 | 反过来，如果让高压气体“嘭”一下释放出来，猛地膨胀，它就会疯狂吸热，周围就会冷下来。这就是“脉管制冷”技术。这台“超级冰箱”主要由压缩机、旋转阀和冷头三部分组成。今年3月，设备在实验室完成了性能验证，制冷量、降温速度、功耗等核心指标均达到国际先进水平，而成本只有进口设备的2/3。按照规划，一年可生产“超级冰箱”50至100台。这台“超级冰箱”到底有什么用？在量子计算领域，它是量子比特安静计算的“绝对静室”。量子比特极其脆弱，任何一点热量干扰都会让它出错。极低温环境能让它摆脱热噪声，稳定地进行计算。在医疗领域，它是医用核磁共振成像设备的核心部件，让超导磁体稳如磐石。
