Published: April 2021

Abstract
Sea-level rise is an extreme issue for the world that has been scientifically proven. That is why sea-level variability presents a significant role in ocean and air interactions. This study was directed to get seasonal and interannual variability in the Indonesian Seas. The research area is in the Indonesian Seas with coordinates boundaries: of 20°N - 20°S latitudes and 90°E - 150°E longitudes. The data were obtained from the Radar Altimeter Database System (RADS) for Jason Series altimetry (2008 to 2018). The analysis has been performed by taking the correlation between detrended Sea Level Anomaly (SLA) and El Nino Southern Oscillation (ENSO). The outcome showed that the seasonal and interannual sea level anomaly in Indonesian seas fluctuates. Seasonal varieties of Sea Level Anomaly in the Timor Sea, Northen Java Sea, and the Halmahera Sea were low. The high seasonal changes occurred in the Flores Sea, the Natuna Sea, and the Karimata Strait. Besides, the interannual variation of SLA fluctuated from 2009 to 2018. The impact of ENSO on the variance of SLA was strong, with a coefficient correlation of -0.66. In the most recent ten years, the SLA in the Indonesian Seas demonstrated a lowering trend.

Published: April 2021

Abstract
The Tiga Dihaji dam access route function is destined for heavy equipment during the dam construction period. It is located on Tiga Dihaji sub-district, Ogan Komering Ulu Selatan district, South Sumatera, Indonesia. The Tiga Dihaji access route supervisor stated that the planning justification was done using expert judgement based on contour map and local land cover. This method is considered less measurable. Therefore, the Geographic Information System method is offered in this paper to determine the most suitable Tiga Dihaji dam access route. The parameters considered are landslide vulnerability, land cover and construction factors. These parameters are overlaid based on weights determined by the Public Works Department then validated by expert judgement. The new route is proposed using the cost distance method. Based on the analysis, it can be concluded that the cost distance method is more measurable than the planned method, but this method produces a less suitable route in terms of civil engineering.

AbstractBIG has conducted gravity data by using several methods, namely terrestrial gravity and airborne gravity to produce high accuracy of the geoid. The terrestrial gravity survey was carried out using the grid method, and BIG does not have any guidance on the size of the used grid interval size. We try to divide the grid interval into four different sizes of grids, those are km, 10 km, 15 km, and 20 km. A case study in the central part of Java Island, at Semarang and Yogyakarta in 2019, using Scintrex CG-5 relative terrestrial gravimeter equipment. By using the integral stokes and Least Square Collocation (LSC) approaches, the gravimetric geoid is obtained from each grid interval. We compared gravimetric geoid with geometric geoid on 179 vertical benchmarks and obtained the results of the 5 km grid interval having the smallest average value of 0.273 meters ± 0.310 with the most appropriate conformity test.
Analysis of Tax Object Sale Value (NJOP) and Land Value Change On Integrated Zoning Area (Study Case: Pakal and Benowo District, Surabaya City)
Authors: Deviantari U W , Hidayat H , Sari N F 
Published: April 2021

Abstract
The urban development generally will only be focused on certain areas as a center of business and government activities. This causes unbalanced situation at certain areas. The Government of Surabaya City then released Surabaya City’s Regional Medium-Term Development Plan (RPJMD 2016-2021) which stated that the Surabaya City has a strategic area that has the potential to be developed sustainably to support the existence of the development of urban areas in the future. One of them is the integrated area of West Surabaya which located at Pakal and Benowo District. The changes of land value can be analyzed through Land Value Zone Map (ZNT) of 2016 as the beginning period of the RPJMD that has been overlaid with ZNT map of 2020 as the current land value condition and then visualized in thematic maps in the form of bar charts, choropleth and bivariate maps. From this study 66 new land value zones were produced according to land characteristics with the highest Average Indication Value (NIR) Zone in the RKB1 which is Rp 26.623.238/ m2 with range of NJOP Rp 23.000.000 - Rp 31.000.000.While the lowest zone is at KMP4 zone with NIR Rp 1.587.922/m2 and range of NJOP Rp 1.490.000 - Rp 1.655.000. Changes of land values in the districts of Pakal and Benowo as Integrated Areas of West Surabaya have increased significantly each year. The highest increase was in the RKB1 zone that located in Sememi Sub-district with 5537,724% of land value changes. While the lowest increase was in the KMP4 zone that located in Pakal Subdistricts with 50,5% of land value changes. Through buffering analysis of some publict fasilities objects in Pakal and Benowo Districts, it is known that the development carried out by the government of these objects affects the increase of land value around them.

Published: April 2021

Abstract
2-dimensional and 3-dimensional representations have been used in various physical, virtual, and geovisual surface models of the earth - to improve spatial thinking skills. Physical models such as relief maps have been shown to enhance understanding of topographic maps, helping to understand the relationship between 2D representations and 3D objects. Virtual models can support spatial learning, for example, by viewing objects at various angles, by providing an environmental context. This model makes it possible to combine physical models’ interactive benefits with virtual tools’ flexibility and diversity. The term geovisual is an overlay depiction of information scanned through a sensor, processed by a computer. Subsequently, the data obtained are presented to the media so that it is like the real world. It has been built and used in this Tangible research Landscape, which is a real-time geovisual system integrated into a computer connected to a 3D sensor, projector, and supported by GRASS GIS [1]. This geovisual system is then applied for modeling terrain 3-D terrain physically through media, scanned through sensors to a computer, and used to analyze the environment with various effects and graphical simulations. The initial model produced is topography from aerial photographs and DEM from LiDAR, which has a spatial resolution of up to 0.4 meters showing physical processes such as contour lines and water flow, and sediment transportation can be well visualized.

Published: April 2021

Abstract
Population data has an important role in various aspects, such as policy determination, urban planning, and disaster mitigation. But, the most accurate population data in Indonesia is obtained once every 10 years. In this research, population estimation is conducted by applying the Object-Based Image Analysis (OBIA) classification method to detect the residential area. The OBIA classification utilizes aerial photogrammetry data and DSM & DTM of LiDAR. Then the population estimation is generated by the calculation of mathematical demographics and linear regression. Based on the results, OBIA classification produces a high accuracy land use / land cover map, assigned from the accuracy assessment using confusion matrix with kappa coefficient of 0.929 and overall accuracy of 95.24%. While, the habitable surface area classification achieves a high accuracy map with kappa coefficient of 0.86 and overall accuracy of 92.86%. The population estimation results, reveal that the linear regression method has a smaller error than the mathematical demographic method. The MAE, MAPE, RMSE, and RRMSE in Wisma Menanggal values are 40, 21%, 45, dan 0.25, while the ones of Gayungsari Timur are 23, 18%, 34, dan 0.278. In addition to the small error value, the MAE, MAPE, RMSE, and RRMSE values indicate that the population estimation produced by the linear regression model is most optimal.

Published: April 2021

Abstract
In the accompanying article, Mosites et al. (Am J Epidemiol. 2021;190(11):2432–2436) evaluate data sources that enumerate people experiencing homelessness in the United States with respect to their strengths and limitations for conducting epidemiologic research in homeless populations. We largely agree with their key arguments, yet offer additional points that provide important context about these data for researchers and other stakeholders. Overall, we believe that it is possible to address many of the noted shortcomings of these data, and once addressed, the data could be more effectively leveraged to improve the health, housing stability, and quality of life of people experiencing homelessness.
Mouse Mandibular Retromolar Taste Buds Associated With a Mucus Salivary Gland

Published: April 2021

Abstract
We have characterized a recently rediscovered chemosensory structure at the rear of the mandibular mucosa in the mouse oral cavity originally reported in the 1980s. This consists of unorganized taste buds, not contained within troughs, associated with the ducts of an underlying minor salivary gland. Using whole-mount preparations of transgenic mice expressing green fluorescent protein under the promoter of taste-signaling-specific genes, we determined that the structure contains taste bud clusters and salivary gland orifices at the rear of each mandible, distal to the last molar and anterior to the ascending ramus. Immunohistochemical analysis shows in the retromolar taste buds expression of the taste receptors Tas2R131 and T1R3 and taste cascade molecules TrpM5, PLCβ2, and GNAT3, consistent with type II taste cells, and expression of GAD1, consistent with type III taste cells. Furthermore, the neuronal marker, calcitonin gene-related peptide, in retromolar mucosa tissue wrapping around TrpM5+ taste buds was observed. RT–PCR showed that retromolar taste buds express all 3 mouse tas1r genes, 28 of the 35 tas2r genes, and taste transduction signaling genes gnat3, plcb2, and trpm5, making the retromolar taste buds similar to other lingual and palate taste buds. Finally, histochemistry demonstrated that the mandibular retromolar secretory gland is a minor salivary gland of mucous type. The mandibular retromolar taste structure may thus play a role in taste sensation and represent a potential novel pharmacological target for taste disorders.
‘En règle et rejeté’: Homelessness and Recognition in Driss Chraïbi’s Les boucs
Authors: Lyons Patrick 
Published: April 2021

Abstract
This article explores the figuration of homelessness in post-war France across national and racial lines in and around Driss Chraïbi’s Les Boucs (1955). After situating Les Boucs within the broader discursive field concerning homelessness in the mid-1950s in France, first it considers Chraïbi’s critique of the character Mac O’Mac, a Christian philanthropist whose expertise on the ‘North African Question’ grants him the power to determine what forms of suffering are deemed morally legible for the French public, and those which are not. Second, it turns to the work that Les Boucs does to secure visibility for North African immigrant workers through its realist treatment of Yalaan Waldik’s descent through the bureaucratic machinery of the French labour market and the spaces of precarious housing. These sections, in dialogue with contemporary discourses surrounding the crisis of the French ‘sans-abris’, illuminate a marked contrast between what this article names epidemic and endemic forms of ‘homelessness’. That is, while the ‘sans-abris’ are portrayed as a population in crisis, the precarious housing of North African workers is naturalized into an essential component of national reconstruction.
The Transposable Element Environment of Human Genes Differs According to Their Duplication Status and Essentiality

Published: April 2021

Abstract
Transposable elements (TEs) are major components of eukaryotic genomes and represent approximately 45% of the human genome. TEs can be important sources of novelty in genomes and there is increasing evidence that TEs contribute to the evolution of gene regulation in mammals. Gene duplication is an evolutionary mechanism that also provides new genetic material and opportunities to acquire new functions. To investigate how duplicated genes are maintained in genomes, here, we explored the TE environment of duplicated and singleton genes. We found that singleton genes have more short-interspersed nuclear elements and DNA transposons in their vicinity than duplicated genes, whereas long-interspersed nuclear elements and long-terminal repeat retrotransposons have accumulated more near duplicated genes. We also discovered that this result is highly associated with the degree of essentiality of the genes with an unexpected accumulation of short-interspersed nuclear elements and DNA transposons around the more-essential genes. Our results underline the importance of taking into account the TE environment of genes to better understand how duplicated genes are maintained in genomes.
Genetic Mapping by Duplication Segregation in Salmonella enterica
Authors: Camacho Eva M , Casadesús Josep 
Published: April 2021

Abstract
MudP and MudQ elements were used to induce duplications in Salmonella enterica by formation of a triple crossover between two transduced fragments and the host chromosome. The large size (36 kb) of MudP and MudQ is a favorable trait for duplication formation, probably because homology length is a limiting factor for the central crossover. Additional requirements are a multiplicity of infection of 2 or higher in the infecting phage suspensions (which reflects the need of two transduced fragments) and an exponentially growing recipient (which reflects the need of a chromosome replication fork). We describe a set of 11 strains of S. enterica, each carrying a chromosomal duplication with known endpoints. The collection covers all the Salmonella chromosome except the terminus. For mapping, a dominant marker (e.g., a transposon insertion in or near the locus to be mapped) is transduced into the 11-strain set. Several transductants from each cross are grown nonselectively, and haploid segregants are scored for the presence of the marker. If all the segregants contain the transduced marker, it maps outside the duplication interval. If the marker is found only in a fraction of the segregants, it maps within the duplicated region.

Published: April 2021

Abstract
rec7 is involved in intra- and intergenic meiotic recombination in all tested regions of the genome of the fission yeast Schizosaccharomyces pombe. Segregational analysis in a rec7 gene disruption mutant revealed frequent occurrence of two-spored asci. Spores giving rise to diploid colonies were shown to derive from skipping of the second meiotic division. Nondisjunction of homologous chromosomes at the first meiotic division was also frequent. The cytological structures and processes, such as formation of linear elements, pairing of homologous chromosomes, and clustering of telomeres and centromeres, are regular in the mutant. Northern blot experiments revealed meiosis-specific expression of rec7. Screening of a meiotic cDNA library also identified transcripts from the opposite strand in the rec7 region. A Rec7-GFP fusion protein was localized in the nucleus of whole cells before karyogamy, during prophase, and after meiosis I. On spreads of prophase nuclei approximately 50 foci of Rec7-GFP were counted. Some of the observed phenotypes of the disruption mutant and the N-terminal sequence homology suggest that Rec7p is a functional homolog of Rec114p of Saccharomyces cerevisiae. The observed phenotypes of the disruption and the appearance of Rec7-GFP in mating haploid cells and after meiosis I are consistent with Rec7p functions before, during, and after meiotic prophase.
Coupling ofSaccharomyces cerevisiaeEarly Meiotic Gene Expression to DNA Replication Depends UponRPD3andSIN3
Authors: Lamb Teresa M , Mitchell Aaron P 
Published: April 2021

AbstractIt has been established that meiotic recombination and chromosome segregation are inhibited when meiotic DNA replication is blocked. Here we demonstrate that early meiotic gene (EMG) expression is also inhibited by a block in replication. Since early meiotic genes are required to promote meiotic recombination and DNA division, the low expression of these genes may contribute to the block in meiotic progression. We have identified three Hur– (HU reduced recombination) mutants that fail to couple meiotic recombination and gene expression with replication. One of these mutations is in RPD3, a gene required to maintain meiotic gene repression in mitotic cells. Complete deletions of RPD3 and the repression adapter SIN3 permitted recombination and early meiotic gene expression when replication was inhibited with hydroxyurea (HU). Biochemical analysis showed that the Rpd3p-Sin3p-Ume6p repression complex does exist in meiotic cells. These observations suggest that repression of early meiotic genes by SIN3 and RPD3 is critical for the normal response to inhibited replication. A second response to inhibited replication has also been discovered. HU-inhibited replication reduced the accumulation of phospho-Ume6p in meiotic cells. Phosphorylation of Ume6p normally promotes interaction with the meiotic activator Ime1p, thereby activating EMG expression. Thus, inhibited replication may also reduce the Ume6p-dependent activation of EMGs. Taken together, our data suggest that both active repression and reduced activation combine to inhibit EMG expression when replication is inhibited.
A Screen for Modifiers ofdecapentaplegicMutant Phenotypes Identifieslilliputian, the Only Member of the Fragile-X/Burkitt's Lymphoma Family of Transcription Factors inDrosophila melanogaster

Published: April 2021

AbstractThe decapentaplegic (dpp) gene directs numerous developmental events in Drosophila melanogaster. dpp encodes a member of the Transforming Growth Factor-β family of secreted signaling molecules. At this time, mechanisms of dpp signaling have not yet been fully described. Therefore we conducted a genetic screen for new dpp signaling pathway components. The screen exploited a transvection-dependent dpp phenotype: heldout wings. The screen generated 30 mutations that appear to disrupt transvection at dpp. One of the mutations is a translocation with a recessive lethal breakpoint in cytological region 23C1-2. Genetic analyses identified a number of mutations allelic to this breakpoint. The 23C1-2 complementation group includes several mutations in the newly discovered gene lilliputian (lilli). lilli mutations that disrupt the transvection-dependent dpp phenotype are also dominant maternal enhancers of recessive embryonic lethal alleles of dpp and screw. lilli zygotic mutant embryos exhibit a partially ventralized phenotype similar to dpp embryonic lethal mutations. Phylogenetic analyses revealed that lilli encodes the only Drosophila member of a family of transcription factors that includes the human genes causing Fragile-X mental retardation (FMR2) and Burkitt's Lymphoma (LAF4). Taken together, the genetic and phylogenetic data suggest that lilli may be an activator of dpp expression in embryonic dorsal-ventral patterning and wing development.
Molecular and Functional Mapping of the Piebald Deletion Complex on Mouse Chromosome 14

Published: April 2021

Abstract
The piebald deletion complex is a set of overlapping chromosomal deficiencies surrounding the endothelin receptor B locus collected during the Oak Ridge specific-locus-test mutagenesis screen. These chromosomal deletions represent an important resource for genetic studies to dissect the functional content of a genomic region, and several developmental defects have been associated with mice homozygous for distinct piebald deletion alleles. We have used molecular markers to order the breakpoints for 20 deletion alleles that span a 15.7–18-cM region of distal mouse chromosome 14. Large deletions covering as much as 11 cM have been identified that will be useful for regionally directed mutagenesis screens to reveal recessive mutations that disrupt development. Deletions identified as having breakpoints positioned within previously described critical regions have been used in complementation studies to further define the functional intervals associated with the developmental defects. This has focused our efforts to isolate genes required for newborn respiration and survival, skeletal patterning and morphogenesis, and central nervous system development.
