The proliferation of urban development with concentration in population and human-environment interaction has intensified around urban environments. This has resulted in the degradation of urban environments, overuse of natural resources and widespread pollution of ecosystems, The patterns of design initiatives continue to follow unsustainable path with impacts on stream ecosystems. Accordingly, the paper adopts geospatial information systems and sustainability principles for the identification and sequential mapping of stressors impeding natural systems in Southern Mississippi. The results not only reveal that the study area experienced some significant changes in its watershed environments, but the stream habitat ecosystem remains under stress. The recommendations for mitigating the problems range from policy considerations to the adoption of ecosystem approach.

This paper focuses on the use of models for increasing the precision of estimators in large-area forest surveys. It is motivated by the increasing availability of remotely sensed data, which facilitates the development of models predicting the variables of interest in forest surveys. We present, review and compare three different estimation frameworks where models play a core role： model-assisted, model-based, and hybrid estimation. The first two are well known, whereas the third has only recently been introduced in forest surveys. Hybrid inference mixes design- based and model-based inference, since it relies on a probability sample of auxiliary data and a model predicting the target variable from the auxiliary *** review studies on large-area forest surveys based on model-assisted, model- based, and hybrid estimation, and discuss advantages and disadvantages of the approaches. We conclude that no general recommendations can be made about whether model-assisted, model-based, or hybrid estimation should be preferred. The choice depends on the objective of the survey and the possibilities to acquire appropriate field and remotely sensed data. We also conclude that modelling approaches can only be successfully applied for estimating target variables such as growing stock volume or biomass, which are adequately related to commonly available remotely sensed data, and thus purely field based surveys remain important for several important forest parameters.

High-density single nucleotide polymorphism （SNP） genotyping arrays are powerful tools that can measure the level of genetic polymorphism within a population. To develop a whole-genome SNP array for oil palms, SNP discovery was performed using deep resequencing of eight libraries derived from 132 Elaeis guineen- sis and Elaeis oleifera palms belonging to 59 origins, resulting in the discovery of 〉3 million putative SNPs. After SNP filtering, the Illumina OP200K custom array was built with 170 860 successful probes. Phenetic clustering analysis revealed that the array could distinguish between palms of different origins in a way consistent with pedigree records. Genome-wide linkage disequilibrium declined more slowly for the commercial populations （ranging from 120 kb at r2 = 0.43 to 146 kb at r2 = 0.50） when compared with the semi-wild populations （19.5 kb at r2 = 0.22）. Genetic fixation mapping comparing the semi-wild and commercial population identified 321 selective sweeps. A genome-wide association study （GWAS） detected a significant peak on chromosome 2 associated with the polygenic component of the shell thick- ness trait （based on the trait shell-to-fruit; S/F %） in tenera palms. Testing of a genomic selection model on the same trait resulted in good prediction accuracy （r = 0.65） with 42% of the S/F % variation explained. The first high-density SNP genotyping array for oil palm has been developed and shown to be robust for use in genetic studies and with potential for developing early trait prediction to shorten the oil palm breeding cycle.

Thirty-day readmission rates and reasons were *** Calculated sample size was not achieved due to coronavirus disease 2019;240 patients were randomized into INT and SOC arms. 30-d readmission rate was 33.75%, 35.83% in the INT vs 31.67% in the SOC arm(P = 0.59). The top reason for 30-d readmission was hepatic encephalopathy(HE, 32.10%). There was a lower rate of 30-d readmissions for HE in the INT(21%) vs SOC arm(45%, P = 0.03). There were fewer 30-d readmissions in patients who attended early outpatient follow-up(n = 17, 23.61% vs n = 55, 76.39%, P = 0.04).CONCLUSION Our 30-d readmission rate was higher than the national rate but reduced by interventions in patients with dC with HE and early outpatient follow-up. development of interventions to reduce early readmission in patients with dC is needed.
