直播吧4月21日讯 据《足球报》记者陈永报道，按行程计划，4月26日，世界足球先生和欧洲金球奖双料得主、世界足坛名宿里瓦尔多将前来青岛看望踢球的儿子，现场观看青岛红狮vs上海嘉定汇龙这场比赛并与球迷互动。

中甲战罢4轮，青岛红狮以3平1负积3分位居第13名。

Chinese researchers have developed a multifunctional electrode coating that addresses key challenges in long-term brain-computer interface (BCI) implantation, including signal loss and tissue adhesion, bringing BCI one step closer to clinical application, the Global Times learned from the research team behind the findings on Sunday. 
As an emerging field combining neuroscience and artificial intelligence (AI), BCI faces a major challenge of ensuring long-term compatibility between electrodes and brain tissue. Previous clinical trials showed that immune responses could cause implanted electrodes to retract after just three months, severely reducing signal quality and the number of available channels. 
This problem stems from chronic inflammation triggered by implants, which creates insulating scar tissue around electrodes and separates them from neurons. Irreversible adhesion between electrodes and brain tissue after long-term implantation also makes device removal risky, potentially causing brain injury during follow-up surgeries.
Experiments showed that flexible neural electrodes coated with this material could operate stably in the brain for more than 300 days and could be safely removed without causing damage. This means the universal coating technology can make electrodes not only operate stably over the long term but can also be safely removed and replaced after aging, paving the way for long-term BCI applications.
Developed by the research team led by Zhang Wei at the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, associated with Beijing Tiantan Hospital, Shanghai Institute of Microsystem and Information Technology and NeuroXess, a high-tech life science company specializing in BCI technologies, the cationic alternating peptide electrode coating preserves electrode flexibility and conductivity, while offering antibacterial, anti-protein adsorption and immune-rejection-inhibiting functions. 
A 300-day animal study showed the coating's effectiveness. Bare electrodes experienced a sharp loss of recording capability after 90 days of implantation and could barely detect neuronal signals after 300 days. In contrast, coated electrodes maintained stable recording channels and consistently captured neural signals above 155 microvolts. 
In terms of neural modulation, after 300 days of implantation, conventional electrodes required a current of 100 microamps to induce weak limb responses, while coated electrodes triggered clear movements with only 2 microamps, improving modulation efficiency by 50 times. 
Notably, the removal tests highlighted a key advantage of the coating that electrodes no longer form irreversible bonds with brain tissue. In the experiments, the coated electrodes were removed intact, with minimal damage to the surrounding brain tissue, Zhang told the Global Times on Sunday.
。从前4轮的表现来说，青岛红狮的防守非常顽强，三个丢球并列中甲第四少，但两个进球又并列中甲第二少。

对于小里瓦尔多的引进，青岛红狮俱乐部总经理刘雨介绍了引进的初衷，这主要基于两个层面的考量：“其一，竞技层面的考量，今年是青岛红狮的第二个中甲赛季，俱乐部希望引进质量更高一些的外援，能够给球队带来更多的帮助，现在来看他也比较适合我们球队；其二，影响力层面的考量，在同等性价比的情况下，引进一名影响力更大的外援，可以提升青岛红狮的号召力，包括增加和青岛球迷之间的黏性。青岛是一座足球城，更是一城双超，由此作为中甲球队，也希望展现自己的风格和特色。小里瓦尔多的父亲在中国享有很高的知名度，更是在2002年世界杯上和中国足球有过交集，由此从竞技和影响力双重考虑，我们引进了小里瓦尔多。”

青岛红狮俱乐部已为小里瓦尔多解决了后顾之忧，他有一个8岁的儿子和2个双胞胎女儿，俱乐部联系了国际学校并出资安排，这也让小里瓦尔多非常认可。

小里瓦尔多的个人素质得到了俱乐部的高度认可，他非常自律，非常敬业，也非常有礼貌，“这些方面，我们俱乐部上上下下都是非常认可的。

E | 在此前接受本报专访时，小里瓦尔多就高度赞美了青岛，而在3月24日的球迷开放日上，小里瓦尔多再度表示了对青岛市、青岛红狮俱乐部和青岛球迷的好感，当时小里瓦尔多也透露，父亲会来青岛为自己加油助威。现在日期确定了，4月26日，青岛红狮主场对阵辽宁铁人，里瓦尔多将亲临赛场。

前4轮比赛3平1负，青岛红狮表现得非常顽强，但球队的积分情况并不理想，而要想保持防守强度的同时提升攻击力，包括小里瓦尔多在内的外援非常重要。小里瓦尔多的敬业态度和能力都获得了俱乐部的认可，包括他在两场比赛中攻入了两个进球，虽然都是点球，但比赛中也创造了不少威胁，此外他还有一个好球被吹掉。

小里瓦尔多身高1.87米，主打中锋，也可客串影锋、右边锋等位置。小里瓦尔多在2020年身价曾经达到了110万欧元，目前身价约90万欧元。作为中锋，小里瓦尔多需要队友“喂饼”，包括整个体系的帮助，这其实也是青岛红狮下一步需要提升的地方。​​​​。
