Photo: XinhuaTravelers from the Taiwan region are being cautioned against traveling to Uganda after reports that several Taiwan residents had their travel documents issued by the Taiwan authorities seized or were denied entry in early August, amid a series of moves recently in Africa related to the one-China principle. A mainland expert noted that the more "Taiwan independence" forces seek international space, the narrower their room for maneuver will become.
According to Taiwan regional media outlet United Daily News (UDN) on Saturday, a Taiwan resident holding a valid Ugandan work permit had his so-called "passport" confiscated by Ugandan immigration officials on August 3 after arriving at Entebbe International Airport (EBB) on a domestic flight. The officials cited a "new policy" but have yet to return the "passport." 
In a separate but similar incident, another Taiwan regional resident was also denied entry by Ugandan immigration officials at EBB and deported on the same flight, according to UDN.
The two incidents occurred at the same airport within a short period of time, with the authorities' actions escalating from the confiscation of travel documents to outright denial of entry and deportation, a travel agency was quoted by the report as saying.
The developments suggest that the measures being taken by Ugandan authorities may go beyond isolated incidents and could represent a systematic pattern of enforcement targeting people from the region, with signs that the situation is "continuing to escalate," per the report by UDN.
However, so-called Taiwan regional foreign affairs authorities stated that the relevant cases may be connected with the measure rolled out by the Taiwan region to temporarily suspend visa issuance to Ugandan nationals and bar their entry amid the worsening Ebola epidemic, according to Taiwan's local media CNA, adding it will keep negotiating with Uganda and offer support to impacted people.
Prior to this incident, several African countries had already adjusted their wording and entry policies concerning Taiwan region. According to a previous UDN report in July, on the registration page for South Africa's Electronic Travel Authorization (ETA) system, Taiwan is listed as "Taiwan, China" in the dropdown menu for place of issue of travel documents. Similarly, the international dialing code +886 is marked "Taiwan, China" under the phone number section.
That same month, the Moroccan Embassy in Japan suspended its Visa Confirmation Letter (VCL) review process for travelers from Taiwan region starting July 23, while the regional authorities stopped accepting visa applications from Moroccan nationals in retaliation, according to CNA.
But some netizens from the island commented that they had "gotten used to this situation". One remarked, "It was Papua New Guinea a few days ago, and now Morocco again. Taiwan's foreign affairs department sure has an easier job these days."
After the government of Papua New Guinea announced the closure of the "Taipei Economic Office in Papua New Guinea," Chinese Foreign Ministry spokesperson Lin Jian also said during a press conference on July 16 that China highly commends the decision and it demonstrates once again that upholding the one-China principle is where international public opinion trends and the arc of history bends. 
Earlier in April, three African countries, Seychelles, Mauritius, and Madagascar revoked flight permit to cross their countries without prior warnings before regional leader Lai Ching-te's planned trip to Eswatini.
Zheng Jian, a professor at the Graduate Institute for Taiwan Studies at Xiamen University in East China's Fujian Province, told the Global Times that the Democratic Progressive Party (DPP) has pushed to internationalize the Taiwan question and expand "Taiwan independence" activities abroad, directly challenging the one-China principle widely upheld by the international community and provoking pushback.
International community, including African countries, would not choose to support "Taiwan independence" in their diplomatic decisions, and the more the separatists seek international space, the narrower their room for maneuver will become, the expert noted.
Against the backdrop of the one-China principle, attributing such entry restrictions solely to the Ebola-related policy would amount to misplaced wishful thinking, he said. In truth, DPP authorities should not ignore that all the setbacks Taiwan region faces internationally nowadays are brought about by "Taiwan independence" separatist activities, Zheng said.
A spokesperson from Taiwan Affairs Office of the State Council, Zhang Han, said during a press conference on July 22 that facts have proven time and again that the one-China principle is a basic norm governing international relations and a universal consensus among the international community. 
"Upholding the one-China principle aligns with righteousness and represents the irresistible historical trend. A just cause gains wide support, whereas an unjust one garners little backing. The DPP authorities stubbornly adhere to their separatist 'Taiwan independence' stance. Acting against the tide of history, they will only encounter repeated setbacks internationally," Zhang added.
。    　　当地时间8月20日，谷歌宣布，其开源端侧模型家族Gemma的总下载量已突破10亿次。这款由谷歌DeepMind推出的开源大模型，自发布以来，全球开发者基于它衍生出超10万个定制变体，形成名为“Gemmaverse”的开源生态。
　　谷歌列举了多个Gemma家族应用场景：从太空本地图像分析、医疗报告标准数字化、癌症创新治疗方案再到动物语言识别，Gemma家族模型正实实在在地应用到各个垂直行业。　　其中，以Gemma为基座的模型在生物医药科研领域产出了多项标志性成果。谷歌一方面推出面向医疗场景的垂直模型MedGemma，支撑医疗报告结构化、医学影像辅助分析等应用；另一方面联合科研机构，依托Gemma底座攻坚癌症机制研究。

C | 　　传统的癌症疫苗治疗思路，是让免疫系统通过识别身份标签来识别敌人。

D | 但这面临一个“瞄准困境”：一般来说，肿瘤的“身份标签”取自肿瘤本身,但很多肿瘤细胞表面缺少能被免疫T细胞识别的、独特的“身份标签”（即肿瘤特异性抗原），同时，它们还主动穿上“防护服”（如高表达PD-L1蛋白），成为所谓的“冷肿瘤”。结果就是，对于“冷肿瘤”，免疫系统即使大军压境，也像得了“脸盲症”，看不见敌人，或者看见了也被强行抑制，导致治疗无效。　　针对免疫治疗难以起效的“冷肿瘤”难题，C2S-Scale按活跃程度排序，将单细胞基因表达数据转化为类文本的“基因句子”，让大语言模型能直接“读”懂细胞。随后，该模型完成4000余种药物的虚拟筛选，预测出silmitasertib联合低剂量干扰素的用药组合。　　C2S-Scale锁定的候选药物中，仅10%-30%在过往文献中被提及，其余与筛选目标无已知关联。最终被选中的是silmitasertib（CX-4945），一种CK2激酶抑制剂。　　这一AI提出的全新治疗假说，后续在人源活细胞实验中得到验证，研究团队用模型训练时从未见过的人类神经内分泌细胞进行实验，结果是单独用药无效果，单用低剂量干扰素只有轻微提升，两者联用后抗原呈递提升约50%，证实联用方案可显著提升抗原呈递水平，属于少数AI产出全新癌症治疗机制并获得实验室验证的案例，有望提升肿瘤细胞抗原呈递能力，把冷肿瘤转化为对免疫治疗敏感的热肿瘤。

E | 　　该模型相关成果已对外开源，可供全球科研团队继续拓展研究。需要注意的是，该发现目前仅停留在体外细胞实验阶段，尚未进入临床。　　随着下载量冲高，Gemma证明开源大模型不再局限对话生成，能够直接介入原始生物数据挖掘，深度探索癌症治疗新机制，为AI医药科研提供低成本的技术底座。（文章来源：科创板日报）。
