Let M be a smooth manifold and F a Morse-Bott foliation with a compact critical manifold Σ⊂M. Denote by D(F) the group of diffeomorphisms of M leaving invariant each leaf of F. Under certain assumptions on F it is shown that the computation of the homotopy type of D(F) reduces to three rather independent groups: the group of diffeomorphisms of Σ, the group of vector bundle automorphisms of some regular neighborhood of Σ, and the subgroup of D(F) consisting of diffeomorphisms fixed near Σ. Examples of computations of homotopy types of groups D(F) for such foliations are also presented.

The design and operation of naturally ventilated environments rely on adaptive models. The International standard ISO 17772-1:2017 incorporated an adaptive model into the ISO standards framework, which was based on the SCATs Database for office buildings. To verify whether the adaptive thermal comfort zone of the ISO 17772-1 standard can effectively evaluate naturally ventilated environments across different building types worldwide, the analysis was conducted using 59,478 naturally ventilated environment data selected from the Chinese Thermal Comfort Dataset, ASHRAE Global Thermal Comfort Database II, SCATs Database, and ASHRAE RP-884 Database. The results revealed differences in thermal environments among various building types, with neutral temperatures for occupants in offices, residences, and classrooms being 22.3 ℃, 23.2 ℃, and 21.8 ℃, respectively, directly related to the mean operative temperatures they experienced. The acceptable thermal environment data for offices, residences, and classrooms were 63.4 %, 57.3 %, and 78.8 %, respectively, within the comfort zone of the ISO 17772-1 standard. When the outdoor temperature was 10–30 ℃, the ISO 17772-1 standard evaluated the acceptable thermal environments for offices and classrooms well. However, a significant portion of the acceptable thermal environments in residences exceeded the comfort zone defined by this standard. Additionally, based on these data, adaptive models and corresponding adaptive thermal comfort zones were established for offices (slope: 0.2295), residences (slope: 0.3041), and classrooms (slope: 0.2789). These findings provide references for the establishment and improvement of the adaptive model in ISO 17772-1 standard.

Plastic products offer remarkable convenience for modern life. However, growing concerns are emerging regarding the potential health hazards posed by nanoplastics, which formed as plastics break down. Currently, the biological effects and mechanisms induced by nanoplastics are largely underexplored. In this study, we report that polystyrene nanoplastics can enter the bloodstream and enhance thrombus formation. Our findings show that polystyrene nanoplastics adsorb plasma proteins, particularly coagulation factor XII and plasminogen activator inhibitor-1, play a key role in this process, as demonstrated by proteomics, bioinformatic analyses, and molecular dynamics simulations. The adsorption of these proteins by nanoplastics is an essential factor in thrombosis enhancement. This newly uncovered pathway of protein adsorption leading to enhanced thrombosis provides new insights into the biological effects of nanoplastics, which may inform future safety and environmental risk assessment of plastics.

The above article, published online on 29 April 2011, in Wiley Online Library (wileyonlinelibrary.com), and has been retracted by agreement between the journal Editor-in-Chief, Prof. Christoph Plass; the Union for International Cancer Control; and John Wiley and Sons Ltd. A third party reported that they had detected image similarities between figures 3B and 3F. The publisher requested original raw data and images for all Western Blot figures included in the published article, and in response the authors shared what they reported as raw images. A detailed investigation by the editors revealed additional irregularities in the raw data, including the discovery that the data for the Akt and p-Akt bands in Figure 5A had been manipulated between the original images and those presented in the published article. The retraction has been agreed to as the results presented in the article can no longer be considered reliable. The authors disagree with the retraction.
