1项目背景 “水田共生复合养殖摩天楼”，这是我们提出的一个概念，通过我们现有的科技，解决世界上最严重的问题，即过度甚至失控的人口增长造成的粮食危机，并且由于城市化与交通运输造成的环境与空气质量的恶化。我们选择北京为研究城市，他拥有大多数超级城市的特点与缺陷，同时又是一个很特殊的样本。北京在35年间，由一座仅有750万人口的城市成长为现在拥有2300万人口的超级城市。根据预测2050年北京的人口将达到5000万人。城市发展对原有农业结构造成了很大的影响。现今的北京仅仅22%的瓜果蔬菜可以自给自足，根据统计及预测，2050年之前，北京的可耕作土地将必定趋近于0%。现今北京城区拥有25个重要的交通枢纽，当然，对于一个2000万人口的城市，这还是不够的。

TUNED MECHANICAL PROPERTIES ACHIEVED BY VARYING POLYMER STRUCTURE-KNOWLEDGE THAT GENERATES NEW MATERIALS FOR TISSUE ENGINEERING

引用

Chinese Journal of Polymer Science 2007年第2期25卷 113-118页

作者： Anna Finne Wistrand Ann-christine Albertsson Department of Fiber and Polymer Technology Royal Institute of TechnologyStockholmSweden

By changing both the monomer composition and the polymer structure, we have varied the mechanical properties of resorbable polymers. The polymers were synthesized by ring-opening polymerization using L-lactide （LLA）, ε-caprolactone （εCL）, trimethylene carbonate （TMC） and 1,5-dioxepan-2-one （DXO） as monomers. Well-defined triblock copolymers, microblock copolymers and networks have been evaluated, and comparisons between them show that it is possible to tune the mechanical properties. Triblock copolymers with an amorphous middle block of poly（1,5-dioxepan-2- one）（PDXO） and semi-crystalline end-blocks of poly（ε-caprolactone）（PCL） were stronger and had a higher strain at break than triblock copolymers with poly（L-lactide）（PLLA） as end-blocks. Polymers with both DXO and TMC in the amorphous middle-block and PLLA as end-blocks showed a lower stress at break, but the material gained elasticity, a property which is very valuable in tissue engineering. Mechanical properties of networks, synthesized by a novel method, containing PDXO and PCL are also presented. Although it is difficult to compare them with the uncross-linked polymers, this is an additional way to modify and widen the properties.

Link prediction in complex networks via modularity-based belief propagation

Link prediction aims at detecting missing, spurious or evolving links in a network, based on the topological information and/or nodes＇ attributes of the network. Under the assumption that the likelihood of the existence of a link between two nodes can be captured by nodes＇ similarity, several methods have been proposed to compute similarity directly or indirectly, with information on node degree. However, correctly predicting links is also crucial in revealing the link formation mechanisms and thus in providing more accurate modeling for networks. We here propose a novel method to predict links by incorporating stochastic-block-model link generating mechanisms with node degree. The proposed method first recov- ers the underlying block structure of a network by modularity-based belief propagation, and based on the recovered block structural information it models the link likelihood between two nodes to match the degree sequence of the network. Experiments on a set of real-world networks and synthetic networks generated by stochastic block model show that our proposed method is effective in detecting missing, spurious or evolving links of networks that can be well modeled by a stochastic block model. This approach efficiently complements the toolbox for complex network analysis, offering a novel tool to model links in stochastic block model networks that are fundamental in the modeling of real world complex networks.

Role of Mdm2 and Mdmx in DNA repair

引用

Journal of Molecular Cell Biology 2017年第1期9卷 69-73页

作者： christine M. Eischen Department of Cancer Biology Sidney Kimmel Cancer Center Thomas Jefferson University Philadelphia PA 19107 USA

Mdm2 and Mdmx are critical regulators of the p53 tumour suppressor and are overexpressed in many human malignancies. However, in recent years, their impact on genome instability was shown to be at least, in part, independent of p53. Both Mdm2 and Mdmx inhibit DNA break repair through their association with the Mrell/RadSO/Nbs1 DNA repair complex. Recent evidence indicates that harnessing Mdm2 and/or Mdmx-mediated inhibition of DNA break repair in cancer cells could provide a therapeutic opportunity, particularly for those malignancies that have lost functional p53.

Biomarkers are molecules of biological processes that help in both the diagnosis of human diseases and in follow-up assessments of therapeutic responses. Biomarkers can be measured in many human fluids, such as blood, cerebrospinal fluid, urine, and saliva. The-omics methods(genomics, RNomics, proteomics, and metabolomics) are useful at measuring thousands of markers in a small volume. Saliva is a human fluid that is easily accessible, without any ethical concerns. Yet, saliva remains unexplored in regard to many human disease biomarkers. In this review, we will give an overview on saliva and how it can be influenced by exogenous factors. As we focus on the potential use of saliva as a diagnostic tool in brain disorders(especially Alzheimer's disease), we will cover how saliva is linked to the brain. We will discuss that saliva is a heterogeneous human fluid, yet useful for the discovery of biomarkers in human disorders. However, a procedure and consensus that is controlled, validated, and standardized for the collection and processing of saliva is required, followed by a highly sensitive diagnostic approach.

Valuable Beyond Vulnerable: A Scoping Review on the Contributions of Older Forced Migrants in Post-migration Recovery

International Journal of Disaster Risk Science 2024年第2期15卷 186-197页

作者： Prince Chiagozie Ekoh christine A.Walsh Faculty of Social Work University of CalgaryCalgaryAB T2N 1N4Canada Department of Social Work University of NigeriaNsukka 410001Nigeria

During times of crisis, including pandemics, climate change, and forced migration, much of the discourse in ageing research and intervention centers on the vulnerabilities of older adults. Unfortunately, the valuable contributions of older adults to post-disaster recovery and healing are often overlooked and undervalued. Our aim in this scoping review is to shed light on the critical contributions of older forced migrants to post-migration recovery. We set the scene by introducing the two significant global demographic changes of the twenty-first century: forced migration and ageing. We provide a discourse on older forced migrants, ageing in situations of forced migration, and some of the challenges faced by older forced migrants. We then present some of the substantial roles of older forced migrants in post-migration recovery, including building resilience, contributing to culture and language transfer, providing emotional support, offering mentorship and leadership, participating in community building, and fostering social integration. We close by highlighting some of the lessons that can be drawn from understanding the unique roles played by older adults in post-forced migration recovery and the key actions necessary to promote these roles.

Nanostructured gold films exhibiting almost complete absorption of light at visible wavelengths

Frontiers of Chemical Science and Engineering 2018年第2期12卷 247-251页

Nanostructured known to exhibit properties metal surfaces have been that deviate from that of the bulk material. By simply modifying the texture of a metal surface, various unique optical properties can be observed. In this paper, we present a simple two step electrochemical process combining electrodeposition and anodization to generate black gold surfaces. This process is simple, versatile and up-scalable for the production of large surfaces. The black gold films have remarkable optical behavior as they absorb more than 93% of incident light over the entire visible spectrum and also exhibit no specular reflectance. A careful analysis by scanning electron microscopy reveals that these unique optical properties are due to their randomly rough surface, as they consist in a forest of dendritic microstructures with a nanoscale roughness. This new type of black films can be fabricated to a large variety of substrates, turning them to super absorbers with potential applications in photovoltaic solar cells or highly sensitive detectors and so on.

AIM To clarify risk based upon segment length, diagnostic histological findings, patient age and year of surveillance, duration of surveillance and *** Patients registered with the United Kingdom Barrett's Oesophagus Registry from 9 United Kingdom centers were included. The outcome measures were(1) development of all grades of dysplasia;(2) development of high-grade of dysplasia or adenocarcinoma; and(3) development of adenocarcinoma. Prevalent cases and subjects with < 1 year of follow-up were excluded. The covariates examined were segment length, previous biopsy findings, age at surveillance, duration of surveillance, year of surveillance and *** One thousand and one hundred thirty six patients were included(total 6474 patient-years). Fifty-four patients developed adenocarcinoma(0.83% per annum), 70 developed high-grade dysplasia/adenocarcinoma(1.1% per annum) and 190 developed any grade of dysplasia(3.5% per annum). High grade dysplasia and adenocarcinoma increased with age and duration of surveillance. The risk of low-grade dysplasia development was not dependent on age at surveillance. Segment length and previous biopsy findings were also significant factors for development of dysplasia and *** The risk of development of low-grade dysplasia is independent of age at surveillance, but high-grade dysplasia and adenocarcinoma were more commonly found at older age. Segment length and previous biopsy findings are also markers of risk. This study did not demonstrate stabilisation of the metaplastic segment with prolonged surveillance.
