This article explores the comparison between the probability method and the least squares method in the design of linear predictive models. It points out that these two approaches have distinct theoretical foundations and can lead to varied or similar results in terms of precision and performance under certain assumptions. The article underlines the importance of comparing these two approaches to choose the one best suited to the context, available data and modeling objectives.

In the digital age, the data exchanged within a company is a wealth of knowledge. The survival, growth and influence of a company in the short, medium and long term depend on it. Indeed, it is the lifeblood of any modern company. A companys operational and historical data contains strategic and operational knowledge of ever-increasing added value. The emergence of a new paradigm: big data. Today, the value of the data scattered throughout this mother of knowledge is calculated in billions of dollars, depending on its size, scope and area of intervention. With the rise of computer networks and distributed systems, the threats to these sensitive resources have steadily increased, jeopardizing the existence of the company itself by drying up production and losing the interest of customers and suppliers. These threats range from sabotage to bankruptcy. For several decades now, most companies have been using encryption algorithms to protect and secure their information systems against the threats and dangers posed by the inherent vulnerabilities of their infrastructure and the current economic climate. This vulnerability requires companies to make the right choice of algorithms to implement in their management systems. For this reason, the present work aims to carry out a comparative study of the reliability and effectiveness of symmetrical and asymmetrical cryptosystems, in order to identify one or more suitable for securing academic data in the DRC. The analysis of the robustness of commonly used symmetric and asymmetric cryptosystems will be the subject of simulations in this article.

背景调节性T(Tregs)细胞可以预防自身免疫并控制炎症,在各种自身免疫性或自身炎症性疾病中的研究都表明Treg细胞不足。由于低剂量白细胞介素-2(low-dose interleukin-2,ld-IL2)能够扩增并激活Tregs细胞,因此ld-IL2具有广泛的治疗潜力。目的我们通过一项临床试验观察ld-IL2治疗11种自身免疫性疾病中1种的效果,旨在评估ld-IL2的治疗潜力并选择疾病,以用于进一步的临床开发。方法本研究为前瞻开放性Ⅰ~Ⅱa期临床观察,入选了46例轻中度患者,诊断分别为类风湿关节炎、强直性脊柱炎、系统性红斑狼疮、牛皮癣、白塞病、肉芽肿性多血管炎、大动脉炎、克罗恩病、溃疡性结肠炎、自身免疫性肝炎或硬化性胆管炎。所有患者都接受了ld-IL2(100万IU/天)5天,然后每两周注射一次,维持6个月。所有患者均接受了深入的免疫监测和临床评估。结果在任何疾病类型以及任何合并药物治疗的患者中,ld-IL2都显示出了良好的耐受性。通过经典的免疫表型分析和广泛的免疫表型分析发现所有患者的Tregs细胞均被特异性地扩增激活,而效应T细胞没有被活化,提示ld-IL2具有临床疗效的前景。结论本研究中所采用的IL-2剂量和治疗方案可以选择性地激活和扩增Tregs细胞,并且对于不同的疾病种类以及不同的合并用药都是安全的。这一临床疗效以及初步结果可以为ld-IL2在各种自身免疫和自身炎症性疾病中开展Ⅱ期临床试验观察疗效提供了依据。试验注册号NCT01988506.

20世纪上半叶,实用艺术在法国的发展通常表现在集体创意构思上,巴黎大型百货商场所属的艺术工坊就是例证。本文对莫里斯·杜弗雷纳指导下的“精通”艺术工坊所发布作品的广泛多样性进行了深入研究。首先,是大量装饰艺术设计创造和推广的条件。其次,着重于对两个项目的案例研究:一个是1925年世界博览会上由艺术工坊布置的“精通”展馆,表现了杜弗雷纳极尽奢华风格的室内装饰设计;另一个则是通过电影院不同放映厅的装饰,展现其与娱乐界发展同步的创作。

Bike sharing systems are booming globally as a green and flexible transportation mode, but the flexibility also brings difficulties in keeping the bike stations balanced with enough bikes and docks. Understanding the spatio-temporal bike trip patterns in a bike sharing system, such as the popular trip origins and destinations during rush hours, is important for researchers to design models for bike scheduling and sta- tion management. However, due to privacy and operational concerns, bike trip data are usually not publicly available in many cities. Instead, the station feeds about real-time bike and dock number in stations are usually public, which we refer to as bike sharing system open data. In this paper, we propose an approach to infer the spatio-temporal bike trip patterns from the public station feeds. Since the number of possible trips （i.e., origin-destination station pairs） is much larger than the number of stations, we define the trip infer- ence as an ill-posed inverse problem. To solve this problem, we identify the sparsity and locality properties of bike trip patterns, and propose a sparse and weighted regularization model to impose both properties in the solution. We evaluate our method using real-world data from Washington, D.C. and New York City. Results show that our method can effectively infer the spatio-temporal bike trip patterns and outperform the baselines in both cities.
