研究了供应链中上下游企业间关于质量成本信息的不对称现象,并由此可能产生的谎报问题.建立了以批发价格契约为基础,同时引入第三方质量成本审查策略的契约机制.结果表明:新的契约形式不但可以消除不对称信息的影响,而且通过审查策略对谎报质量成本信息现象进行了有效的抑制.下游企业可以通过合理的提高批发价格,激励上游企业增加质量成本投入,得到相应较高质量水平的产品,对生产有正向激励作用.最后通过算例验证了相关结论.

赤铁矿和针铁矿是自然界常见的风化产物,对气候环境具有灵敏的指示作用.本文利用漫反射光谱技术,分析了长江干流及其主要支流悬浮颗粒物及河漫滩沉积物中赤铁矿和针铁矿的分布特征.结果表明,长江沉积物中可见光漫反射光谱一阶导数赤铁矿特征峰出现在565nm处,针铁矿一阶导数主峰出现在505nm处,次峰出现在435nm处.与以往在黄土研究中的结果不同,长江沉积物中针铁矿一阶导数主峰的峰高普遍低于针铁矿次峰的一阶导数峰高.在长江流域内,干流样品赤铁矿和针铁矿含量变化不大,而上游支流赤铁矿和针铁矿含量总体较低,反映了它们的来源不同和水动力作用影响.长江与黄河沉积物、黄土及粉尘的漫反射光谱数据对比发现,不同环境下赤铁矿和针铁矿含量差别明显,具有一定的气候环境与源区指示意义.

Pancreatic ductal adenocarcinoma (PDAC) is an extremely malignant disease, which has an extremely low survival rate of <9% in the United States. As a new hallmark of cancer, metabolism reprogramming exerts crucial impacts on PDAC development and progression. Notably, arginine metabolism is altered in PDAC cells and participates in vital signaling pathways. In addition, arginine and its metabolites including polyamine, creatine, agmatine, and nitric oxide regulate the proliferation, growth, autophagy, apoptosis, and metastasis of cancer cells. Due to the loss of argininosuccinate synthetase 1 (ASS1) expression, the key enzyme in arginine biosynthesis, arginine deprivation is regarded as a potential strategy for PDAC therapy. However, drug resistance develops during arginine depletion treatment, along with the re-expression of ASS1, metabolic dysfunction, and the appearance of anti-drug antibody. Additionally, arginase 1 exerts crucial roles in myeloid-derived suppressor cells, indicating its potential targeting by cancer immunotherapy. In this review, we introduce arginine metabolism and its impacts on PDAC cells. Also, we discuss the role of arginine metabolism in arginine deprivation therapy and immunotherapy for cancer.

传统观点认为康德把"自在之物"看作是不可认识的,因而康德是不可知论者。本文对这种观点提出异议。无论从认识的对象还是从认识能力来说,世界永远存在着不可认识的"自在之物"。康德认为通过先天形式认识到的是现象,而不是"自在之物"。应该说这是正确的,因为人认识客观世界总是带有主观性、主观成分,因而所认识到的东西不可能是原来的样子,康德称为现象或表象。康德提出的理论理性所追求的最大统一体:灵魂、世界、上帝,以及实践理性所追求的以自由意志为根据的无条件统一体"至善":灵魂不朽,上帝存在,虽然是"自在之物",但却是人们思维的对象。从今天的现实来看,这种观点是可以成立的。
