Numerical simulation of the stochastic dynamics of inclusions in biomembranes in presence of surface tension

The stochastic dynamics of inclusions in a randomly fluctuating biomembrane is simulated. These inclusions can represent the embedded proteins and the external particles arriving at a cell membrane. The energetics of the biomembrane is modelled via the Canham-Helfrich Hamiltonian. The contributions of both the bending elastic-curvature energy and the surface tension of the biomembrane are taken into account. The biomembrane is treated as a two-dimensional sheet whose height variations from a reference frame is treated as a stochastic Wiener process. The lateral diffusion parameter associated with this Wiener process coupled with the longitudinal diffusion parameter obtained from the standard Einsteinian diffusion theory completely determine the stochastic motion of the inclusions. It is shown that the presence of surface tension significantly affects the overall dynamics of the inclusions, particularly the rate of capture of the external inclusions, such as drug particles, at the site of the embedded inclusions, such as the embedded proteins.Comment: 17 pages, 4 figures, to appear in physica

Perbandingan Pemillhan Berulang Ringkas dan Pemilihan Berulang Salingan Penuh-Sib ke Atas Dua Populasi Jagung Manis

Satu program pemilihan ke atas populasl jagung manis Bakti 1 dan Manis Madu telah dijalankan di Ladang Universiti Pertanian Malaysia dengan menggunakan dua kaedah pemilihan berulang, iaitu pemilihan berulang ringkas berasaskan prestasi progeni Sl dan pemilihan berulang salingan penuh-sib. Objektif utama kajian ini ialah untuk menghasilkan populasi-populasi maju dari populasi-populasi asal yang digunakan. Objektif khusus ialah untuk menentukan keberkesanan secara relatif dua kaedah pemilihan tersebut, menentukan pengawalan genetik dan kebolehwarisan luas beberapa ciri penting, menganalisis korelasi antara hasil dan komponen-komponen hasil di dalam populasi penyendirian Bakti 1 dan Manis Madu, dan menganalisis kesan pemilihan. Tiga ciri-ciri pertumbuhan pokok dan sembilan ciri-ciri hasil dan komponen hasil telah dinilai

Faktor Yang Mempengaruhi Keberhasilan Pemerintah Kota Malang Dalam Menangani Tingkat Kriminalitas

Crime is any action or something that is done by an individual, group or community that violates the law or an act of crime, which disturbs the balance or social stability in society. The economic crisis, poverty, unemployment, and social inequality are some of the factors that often trigger criminal acts, especially in big cities including Malang City. This study aims to examine how strong the level of education, poverty, and unemployment can influence crime. The data used in this study is secondary data obtained from the official website of the Central Bureau of Statistics for the City of Malang in 2022. The data that has been collected is then analyzed using regression analysis. The results of this study indicate that poverty and unemployment are important factors either partially or simultaneously to control and prevent crime rates. However, in this study it was found that the level of education in Malang City did not significantly influence the crime rate. Referring to these results, controlling crime in Malang City can be more focused on reducing poverty and unemployment. These two factors have a major contribution to the crime model in Malang City (R2=93%)

Optimizing Regional Potential in Tangerang Regency: Policy Recommendations Based on Cluster Analysis

Tangerang Regency in Banten Province has various potential areas in each sub-district. To optimize this potential, appropriate policies are needed so that the region can develop and make a significant contribution to society. This study aims to analyze and group sub-districts in Tangerang Regency based on their regional potential using the cluster lysis analysis method with the Ward method. The results showed that sub-districts can be grouped into 5 clusters, namely Cluster 1 with the potential for rice, crops, and fisheries production; Cluster 2 with the potential for large population; Cluster 3 with the potential of many populations, area, rice, and crop production, and animal husbandry; cluster 4 with the potential of many populations, area, horticulture, and rice field land use; and cluster 5 with the potential for a large population and rice field land use. The originality of this research lies in the use of cluster analysis methods to group sub-districts based on their regional potential. The results of this study can be used as a reference for district governments in formulating appropriate policies to optimize the potential of areas in each sub-district

Genetic inheritance of multiple traits of blast, bacteria leaf blight resistant and drought tolerant rice lines

Rice (Oryza sativa L.) is a cereal and staple food crop of over half of the world’s population. Blast, bacteria leaf blight and drought stresses affect yield of rice drastically ranging from 1-100% loss depending on the severity of disease and water deficit condition. Resistance and tolerance high yielding varieties of blast (Putra1) and drought (MR219 IR99784-156-137-1-3) respectively and also IRBB60 (bacteria leaf blight) were used. The research considered the genetic inheritance of the new improved lines and their interactions. Pedigree breeding method was used to develop two single, double and three-way (and reciprocal) crosses through marker-assisted selection. Southern blot analysis was used to determine success of introgression of resistance/tolerance genes/QTLs and selection, also validated by phenotyped results. Agro-morphological and yield parameters of the various populations were analysed. The results indicated levels of significant differences amongst and between treatments for non-drought stress (NS) and reproductive drought stress (RS) and their interactions. There were significant variation among parents and improved lines on some traits in NS treatment, but RS significantly affected parameters of DF, FFG, YM and most especially the susceptible parent, while the improved lines were tolerant.  Significant interactions was recorded (P≤0.05) between treatment and variety (Trt*Var.) on PL, T, FFG and GLW. Cluster analysis and PCA of relationship among the 9 traits in the two treatments revealed that each of single, double and three-way (and reciprocal) crosses had good lines either under NS and RS.
