Published: April 2021

Abstract
The influx of information technology to the developing world has increasingly shown its impacts when information technology usage has become a part of daily life. Like its features, online apps have altered the way people interact and do daily activities, especially in urban areas. Conceptually the neighborhood was developed as part of the town planning practice and theory for developed worlds, though it is a universal phenomenon. Therefore, the neighborhood idea requires several adjustments to fit the dynamic third-world country context.
The study aims to observe the characteristics of urban socio-spatial changes in correlation with the use of online apps and review the extent to which it will modify the essential elements used in defining a neighborhood. It uses an exploratory approach to explain the relationship between spatial character changes and socio-cultural community in two neighborhoods in Bandung city as case studies. The compiled data’s correlational analysis shows several changes in the neighborhood elements characters, either spatial or social related, but they are responses to the inadequate public facilities. In conclusion, to some degree, it has not been significant enough to indicate the neighborhood changes and requires further research to see the advanced information technological impact on urban life

Published: April 2021

Abstract
Pathumthani Province is on fertile plains and river valleys offering suitable land for agriculture. In 2019, A large number of agricultural lands, particularly farmland, is accounted for over 40 percent of the total province. However, the revenue of the agricultural sector contributes less than 3 percent of the gross provincial product (GPP), while the industrial sector becomes a major economic-based activity of this province, accounting for half of the GPP revenue. This research seeks an opportunity to enhance economic values and optimize the efficiency of agricultural-related supply chains. The research aims 1) to assess the need assessment of the agricultural sector in the issue of an intelligent exchange for sustainable economic transaction development, 2) to map a relationship between current situations of the agricultural sector and the commercial sector. Through the process of focus group and in-depth interview, the result of this study demonstrated the potential and current problems include the need to exchange agricultural goods/resources. The results could allow for an enhancement of the exchange of goods, especially agricultural products, to increase the potential of connectivity between producers and consumers in Pathumthani.

Published: April 2021

Abstract
Micro-Hydro Power (MHP) is a solution to the need for renewable energy in the era of the industrial revolution 4.0. Its environmentally friendly effect has become a consideration for many people to consider implementing it in their respective places. One of the critical points to realize this is a sustainable MHP management model. This paper discusses the assessment of the MHP management model for electrification in rural areas in Indonesia. There are two objects in this research: Kunci Putih MHP in Jatirunggo Village, Semarang Regency, and the Mbakuhau MHP in Kamanggih Village, East Sumba Regency. This research aims to assess the management model of the Kunci Putih MHP and Mbakuhau MHP from the social-managerial, economic, and technical aspects. This study uses descriptive qualitative methods with gap analysis techniques. The results show that the two locations have different challenges based on three aspects that have been recognizing in international standards. The private sector manages Kunci Putih MHP with a National scale installation operated by the company directly. In contrast, Mbakuhau MHP manages by a credit union collaboration with National Electricity East Sumba. Kunci Putih MHP is driven by the private sector through auction and is responsible for maintenance, project engineering, repair, and equipment maintenance. Mbakuhau MHP can be successful in community-based management because IBEKA (Pro-Poor Public-Private Partnership) gave the community training during construction. The community provides technical training in leadership because Mbakuhau MHP is an electrification solution for isolated villages so that management is better carried out by the community. Therefore, the two cases cannot significantly be compared because they are different in power and scale.

Authors: Prajnawrdhi Tri Anggraini 
Published: April 2021

Abstract
The concept of sustainable development is widely known as an improvement towards the quality of buildings and the environment. Thus, this concept improves the comfort, health, satisfaction, and work performance of people. The city of Denpasar-Bali experienced very high population growth and decreased the quality of the environment and the balance between economic, social, and environmental factors. On the other hand, indigenous villages named Bali Aga villages that spread out across Bali island have building design and settlement concepts that always maintain harmony between humans, nature, and God. This concept has been proven to effectively respond to social, economic, and environmental problems for years. The aim of this paper is to discuss the suitable concepts and criteria for sustainable design and settlement of Denpasar city in the future by learning from Bali Aga concepts. The qualitative content analysis was applied to this study. Interviews with several professional architects in Denpasar were undertaken to explore the common approaches and barriers to sustainable design. Detailed information on indigenous design and settlement concepts gathered from surveys to selected Bali Aga villages. The result shows that Bali Aga’ building and settlement concept is fundamental to create suitable building and settlement concepts for the future development of Denpasar city to maintain economic, social, and environmental balance.

Published: April 2021

Abstract
The problem of meeting housing needs for low-income communities is the inaccessibility of prices on the housing market. The Salatiga government has made efforts to meet this need by building low-cost houses for civil servants that utilize Government Land, thus keeping prices far below standard. As time went on, these cheap houses that belong to civil servants were not used as residential for the owners, but most of them became long-term investments. Based on these problems, the study aims to examine the impact of the low-cost house construction, namely KORPRI Housing in Prajamukti, Salatiga City of residential and investment functions. The method used is quantitative, primary data collected through field observations and interviews with residents and housing provider stakeholders. Meanwhile, secondary data obtained through government agencies and websites. The analysis technique uses a quantitative descriptive method and map overlay. The results showed that the function of houses is 60% for investment by rent out the housing to others, 30% as residential functions for civil servants, and 10% sold to other people. This condition is due to the status of the house is not the owner’s first home, strategic housing location, and triggered by an increase in land value. The contribution of this research is that previous researchers discussed a lot about the construction of cheap houses that received subsidies from the government, whereas in this study, the price reduction was the result of taking land assets belonging to the government in the form of Government Land.

Published: April 2021

Abstract
Public transportation is an effort towards sustainable transportation. The City of Semarang has public transportation such as the Bus Rapid Transit (BRT), called the Bus Trans Semarang. The opening of the Bus Trans Semarang in 2009 continues to grow and increase the number of passengers. However, the number of passengers is still far below the expected target, even though the Bus Trans Semarang service continues to be improved. The decrease in the number of passengers further exacerbated by the existence of restrictions on community activities in Semarang City due to the pandemic COVID-19. Bus Trans Semarang services during the COVID-19 Pandemic need handled or minimized to reduce the risk of spreading COVID-19 to passengers when using the Bus Trans Semarang. This study aspires to determine what service variables are based on passenger preference that needs improvement, especially in the new normal era. The hope is that by knowing these variables, services can be made on the Bus Trans Semarang to increase public transportation use while reducing private vehicles’ use. Thus, Bus Trans Semarang can be suitable public transportation since users’ safety and comfort are essential for the success of public transportation in breaking the COVID-19 chain. This study uses the Importance Performance Analysis (IPA) of passengers. This study produces service variables expected by passengers, namely ease of mode change with other types of vehicles, timeliness of arrival at bus stops or terminals, and health protocol expectations on the Bus by both officers and passengers.

Abstract
Bangkok has expanded considerably between 1991 - 1996. Which, the key factors contributed to the expansion consisted of real estate, business development and manufacturing industry. The horizontal expansion continued until 1991, after that Bangkok has increased its vertical expansion, especially in the inner and urban areas. The increasing in term of population causes the inner zone growth with high concentration rate, however, the suburban areas are characterized as of urban sprawls with the major expansion of road network. Those connectivities cut through the heart of Bangkok with the surrounding provinces. Currently, Bangkok has been continued its expansion in all directions, with high number of private cars and less users’ choices for public transportation, wich resulted in land-use changes, pollution, and traffic problems. The objective of this research is to study pattern of urban expansion and rate of changes in land use and infrastructure development by analyzing the land use changes in Bangkok and metropolitan and infrastructure development during the past 10 years, 2009 – 2019. The comparing of growth can be performed based on the study of satellite imagery, Path 129 Row 50 and Path 129 Row 51. From the result of analysis, it was found that road intersection density had an effect of the urban density areas. Finally, the Land Change Modeler (LCM) was used to explore and recommend for the appropriate ways for urban planning and development corresponding to the changes and responsive to the people in more sustainable way.

ABSTRACT
High-molecular-weight dextrin (WS-1000) was produced from waxy corn starch and enzymatically modified to link glucose by α-1,6 glycosidic bond at the terminal point of the glucose chain, forming MWS-1000. In this study, the physical properties of MWS-1000 were characterized, and the advantages of its use as a food modifier were described. From rheological and calorimetric studies, it was found that MWS-1000 does not undergo retrogradation, but it does not prevent the retrogradation of WS-1000, suggesting that they have no intermolecular interaction in solution. Investigation of the effect of MWS-1000 on the viscoelasticity of gelatinized wheat starch showed that in the linear viscoelastic region, storage modulus decreased and tan δ increased with increase in replaced MWS-1000 content. In addition, it was confirmed that gelatinized starch containing MWS-1000 showed viscoelastic behavior similar to that of commercially available custard cream.
Constructing small genome graphs via string compression
Authors: Qiu Yutong , Kingsford Carl 
Published: April 2021

Abstract

Motivation
The size of a genome graph—the space required to store the nodes, node labels and edges—affects the efficiency of operations performed on it. For example, the time complexity to align a sequence to a graph without a graph index depends on the total number of characters in the node labels and the number of edges in the graph. This raises the need for approaches to construct space-efficient genome graphs.

Results
We point out similarities in the string encoding mechanisms of genome graphs and the external pointer macro (EPM) compression model. We present a pair of linear-time algorithms that transform between genome graphs and EPM-compressed forms. The algorithms result in an upper bound on the size of the genome graph constructed in terms of an optimal EPM compression. To further reduce the size of the genome graph, we propose the source assignment problem that optimizes over the equivalent choices during compression and introduce an ILP formulation that solves that problem optimally. As a proof-of-concept, we introduce RLZ-Graph, a genome graph constructed based on the relative Lempel–Ziv algorithm. Using RLZ-Graph, across all human chromosomes, we are able to reduce the disk space to store a genome graph on average by 40.7% compared to colored compacted de Bruijn graphs constructed by Bifrost under the default settings. The RLZ-Graph scales well in terms of running time and graph sizes with an increasing number of human genome sequences compared to Bifrost and variation graphs produced by VGtoolkit.

Published: April 2021

Abstract

Background
The sensitivity to endocrine therapy assay (SET2,3) predicts treatment outcomes in Stage II-III breast cancer. SET2,3 measures transcription related to estrogen and progesterone receptors (SETER/PR index) and the molecular subtype (RNA4: ESR1, PGR, ERBB2, AURKA) from formalin-fixed paraffin-embedded (FFPE) tissue sections.

Methods
We designed a nested study across 3 pathology laboratories, each testing 60 breast cancers twice in controlled batches. Laboratories macrodissected and directly homogenized the unstained FFPE tumor sections, then performed the QuantiGene Plex bead-based hybridization assay. SET2,3 was calculated centrally using predefined statistical R-scripts and applying pre-defined cutpoints. Concordance correlation coefficient (CCC) was calculated from continuous measurements and Kappa statistic from categorical results. A mixed-effects model estimated contributions to bias (fixed effects) and variance (random effects) from the replicated design.

Results
Intralaboratory (CCC 0.96–0.99) and interlaboratory (CCC 0.98–0.99) SET2,3 results were concordant, with rates of agreement for high/low categorization within (Kappa 0.83–0.93) and between laboratories (Kappa 0.87–0.88). The relative contributions to overall variance of SET2,3 measurements were 96.90% from biological differences between cancers, 0.67% from interlaboratory variability, and 2.44% from residual causes including intralaboratory replicates. Similar results were obtained with SETER/PR, the baseline prognostic index calculated using pathological or clinical tumor and nodal staging information, and the 4 individual genes (ESR1, PGR, ERBB2, and AURKA).

Conclusion
Intra- and interpathology laboratory measurements of SET2,3 and its components were highly reproducible when tested from FFPE tumor sections.
MBSO Algorithm For Handling Energy-Throughput Trade-Off In Cognitive Radio Networks
Authors: Ramchandran M , Ganesh E N 
Published: April 2021

Abstract
Cognitive Radio network (CRN) depends on opportunistic spectrum access and spectrum sensing for improving the wireless networks’ spectrum efficiency. Since throughput maximization can result in high-energy consumption, the spectrum sensing technique should address the energy-throughput trade-off. The spectrum sensing time has to be determined by the considering the residual battery energies of each secondary user (SU). The primary user (PU) interference degrades the throughput of the entire network. Hence, the transmit power level should be determined by considering the PU interference and SU battery energy. This paper proposes the multi-objective brain storm optimization (MBSO) algorithm for handling energy-throughput trade-off in CRN. In this work, the sensing time is adaptively determined based on the residual battery energy of SUs, and the transmit power is determined based on the energy level of the PU signal and the residual battery energy of the SUs. A multi-objective optimization problem is formulated in order to maximize the throughput and minimize the packet error rate (PER) and is solved by applying the MBSO algorithm. Experimental results show that MBSO attains improved throughput, higher residual energy with lesser PER. The spectrum sensing performance is enhanced with higher probability of detection.
Management strategies for aflatoxin risk mitigation in maize, dairy feeds and milk value chains—case study Kenya
Authors: Joutsjoki Vesa V , Korhonen Hannu J 
Published: April 2021

AbstractWidespread aflatoxin contamination of a great number of food and feed crops has important implications on global trade and health. Frequent occurrence of aflatoxin in maize and milk poses serious health risks to consumers because these commodities are staple foods in many African countries. This situation calls for development and implementation of rigorous aflatoxin control measures that encompass all value chains, focusing on farms where food and feed-based commodities prone to aflatoxin contamination are cultivated. Good agricultural practices (GAP) have proven to be an effective technology in mitigation and management of the aflatoxin risk under farm conditions. The prevailing global climate change is shown to increase aflatoxin risk in tropical and subtropical regions. Thus, there is an urgent need to devise and apply novel methods to complement GAP and mitigate aflatoxin contamination in the feed, maize and milk value chains. Also, creation of awareness on aflatoxin management through training of farmers and other stakeholders and enforcement of regular surveillance of aflatoxin in food and feed chains are recommended strategies. This literature review addresses the current situation of aflatoxin occurrence in maize, dairy feeds and milk produced and traded in Kenya and current technologies applied to aflatoxin management at the farm level. Finally, a case study in Kenya on successful application of GAP for mitigation of aflatoxin risk at small-scale farms will be reviewed.
Equivariant K-Theory Classes of Matrix Orbit Closures
Authors: Berget Andrew , Fink Alex 
Published: April 2021

Abstract
The group $G = \textrm{GL}_r(k) \times (k^\times )^n$ acts on $\textbf{A}^{r \times n}$, the space of $r$-by-$n$ matrices: $\textrm{GL}_r(k)$ acts by row operations and $(k^\times )^n$ scales columns. A matrix orbit closure is the Zariski closure of a point orbit for this action. We prove that the class of such an orbit closure in $G$-equivariant $K$-theory of $\textbf{A}^{r \times n}$ is determined by the matroid of a generic point. We present two formulas for this class. The key to the proof is to show that matrix orbit closures have rational singularities.
Remarkable bilaterally asymmetrical gonopores and gonopods in a new genus and species of brachyuran crab from the Ryukyu Islands, Japan (Decapoda: Brachyura: Xanthidae)
Authors: Naruse Tohru , Maenosono Tadafumi , Ng Peter K L 
Published: April 2021

AbstractA new genus and new species of xanthid crab, Mabui calculusn. gen., n. sp., are described from Okinawa Island, Ryukyu Islands, Japan. The new taxon is unique for Brachyura by having bilaterally asymmetrical male gonopods and female gonopores, with the particular reproductive structure always distinctly more developed on one side than in the other. This remarkable condition, so far unique among brachyurans, was observed in all specimens examined (N = 53), except for an undeveloped subadult female. The right chelae of all intact males and large females are almost always larger than the left chela, and each right chela has a large and modified cutting tooth. Other than in the asymmetrical external reproductive structures, the new taxon is morphologically closest to the xanthines Megametope ogaensis Sakai, 1974 and Jacforus cavatus (Rathbun, 1907), but can easily be distinguished by the characters of the carapace, third maxilliped, ambulatory legs, and male pleon.
