Published: April 2023

Abstract
Fruit bodies of the oyster mushroom, Pleurotus, were collected for 5 isolates symbolized by Has.AA-10, Has.AA-11, Has.AA-12, Has.AA-13 and Has. AA-14, which was initially diagnosed according to phenotypic characteristics. Fungal isolates were identified to the species level using the nucleotide sequence analysis method for 5.8S rRNA as P.ostreatus .strain Has.AA-10, P. floridanus strain Has.AA-12, P. cornucopiae strain Has.AA-13, P. cystidiosus strain Has.AA-11 and P. eryngii var. ferulae strain Has.AA-14 and registered in the world Gene Bank at the NCBI website with accession numbers KX688447.1, MK281340.1, KX787088.1, AB115054.1 and KU612924.1, respectively. The purity of pleurotin was tested by high performance liquid chromatography (HPLC) which showed a concentration of 7.68 μg/ml for the purified pleurutin from Pleurotus spp. The results showed that the highest pluorotin was recorded in presence of crushed sunflower seeds and wheat bran compared with the absence of those supplements in all tested media, while the results showed that no pluorutin was recorded as a result of the non-growth of all Pleurotus spp. in all media supplemented with crushed soybeans. The highest plurotin reached 24.67, 24, 21.35 and 20.99 mg/L in the treatment of P. cornucopiae grown in the (wheat straw + rice husks mixture), (barley straw + rice husk mixture), wheat straw and corn cobs supplemented with crushed sunflower seeds, respectively, while the lowest plurotin concentrations were 0.26, 1.13, 2.11 and 2.66 mg/L in Pleurotus eryngii var. ferulae grown in the unsupplemented corn cobs, wheat straw, (wheat straw + rice husks mixture) and (barley straw + rice husks mixture), respectively.
The modification of channel system in Tahai lowland irrigation area to improve drainability

Published: April 2023

Abstract
The Tahai lowland irrigation area relies on rainwater as a source of irrigation water. The channel system network in Tahai is comb-type with a primary channel connected to the Kahayan River and the end of the primary channel is not connected with other flow sources. The end of the secondary channel is also no longer connected with the collector channel. This condition impacts dissolved solids deposition at the end of the channels. Hydraulic simulations need to be conducted to determine the spread of dissolved solids derived from the fields in the existing water channel system. The existing water channel system could be transformed into a one-way flow system with a right collector channel to expedite water drainage into the Kahayan River. This water channel system plan is also modeled and simulated using HEC-RAS. Hydraulic simulations showed an improvement in channel drainability. At the end of the simulation, the number of dissolved solids in the secondary channel in the one-way flow system was less than that in the existing water channel system.

Abstract
Peanut is an important protein source of agricultural commodity in Indonesia because it has high economic value and plays a strategic role in national food supply. In recent years, peanut production across the country has been declining, so it needs to be improved through various efforts such as intensification, land expansion, and per-land increase.The research was conducted from October 2021 to February 2022 at IP2TP Genteng Banyuwangi, used Factorial Randomized Block Design. The first factor was compound NPK fertilizer dosages, i.e. 200; 300 and 400 kg/ha. The second factor was rice straw mulch dosages, i.e. 0; 3 and 6 ton/ha. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT). Compound NPK fertilizer dosages didn’t affect all observation variables. On the other hand, the dose of rice straw mulch had a highly significant effect on plant height at 15 DAP (M2 = 8.99 cm) and 30 DAP (M2 = 22.35 cm). The interaction of compound NPK fertilizers and rice straw mulching doses was associated with branch number 15 DAP (D2M2 = 2.10), pod dry weight per plot (D2M2 = 1.80 kg), and seed production per hectare (D2M2 = 2.48 tons) demonstrated to have a significant impact.

Abstract
Increasing agricultural production, especially rice, uses a lot of chemical fertilizers, which can have a negative effect on the environment. The solution sought to overcome the impact of using chemical fertilizers is using biological organic fertilizer (POH) beyonic startmix, which contains microorganisms that provide plant nutrients, produce growth hormones, and protect plants from pests and diseases. The study aimed to determine the effect of startmix beyonic organic fertilizer on the growth and yield of inpari 30 rice. The study was carried out in the Motekar farmer group’s paddy fields in Jabong Village, Pagaden District, Subang Regency. The study lasted four months, starting from January to April 2018. The study used a field experiment method using a Randomized Block Design (RBD) pattern, which consisted of 2 treatments, namely with fertilization and without fertilization with startmix beyonic biological organic fertilizer, each carried out on three plots with five replicates. Parameters observed included plant height, number of tillers, number of panicles, number of grains per panicle, the weight of 1000 dry grain seeds, and grain yield. The results showed that applying POH significantly affected the number of tillers, panicles, and paddy yields. The yield of dry milled grain with POH was, on average, 7.463 tons/ha, 16.91% higher than without POH fertilization at 6.201 tons/ha on average.

Abstract
In this study, the functional characteristics of composite flour from fermented cassava flour (FCF) and soy protein concentrate (SPC) containing porang glucomannan (PGM) were examined. The composite flour was made from FCF and SPC (9:1). PGM was added at 0, 4, 8, and 12 g in 100 g of composite flour. Wheat flour (WF) and FCF were also evaluated to study each ingredient’s effect. The functional characteristic studied included solvent retention capacity (SRC), oil binding capacity (OBC), emulsion properties, foaming properties, and least gelation concentration. SPC or PGM increased the SRC for water, sodium carbonate, and lactic acid. Adding PGM to the composite flour increased the OBC value. However, SPC slightly decreased the emulsion activity, and PGM decreased the emulsion activity completely. FCF did not have emulsion stability at all, and the presence of SPC or PGM could not improve the emulsion stability. The foam capacity of composite flour containing PGM at the level of 4 and 8 g in 100 g flour did not significantly (p<0.05) differ from that of wheat flour. PGM was able to keep the foam stability of the composite flour. These composite flours might be used to produce cookies.

Abstract
The development of GIS brings several advantages for environmental protection and management in Binh Dinh province. This technology has huge potential to overcome the disadvantages of ground-based monitoring sites and can provide additional information on the geographical representation of environmental quality at the regional level. The objective of this study is to use GIS technology to develop a map for rapid identification of the emission coefficient Kv (Kv), coefficient Kq of receiving water (Kq), and wastewater discharge with columns A and B in national environmental regulations. This study also used the ArcGIS tool and map overlay method to merge data with several GIS’ layers. The results show the maps of emissions coefficient Kv in the province are as 5 regions with a coefficient Kv = 0.6; 0.8; 1.0; 1.2; 1.4 based on the current state of urban development, socio-economy, industrial zones, special-use forests, natural heritages, historical and cultural relics, urban areas, rural areas. For the coefficients Kq (Kq = 0.9) corresponding to the flow rate (Qmean) of receiving water of all rivers, streams, canals, and channels in Binh Đinh province (Qmean < 50 m3/s). The other result shows that the wastewater river basin from the downstream of the river to the estuary or lagoon usually is the zoning of wastewater discharge column B.

Abstract
In recent years, land use changes in Kon Tum province have been significantly transformation. Hence, there is an urgent need for Land Use/Land Cover (LULC) change assessment in Kon Tum province during two recent decades. The present study employed GIS technique to examine potential changes in different land-use types between 2005-2010, 2010-2015 and 2015-2020 periods. To do this, several LULC maps representing the existing condition of LULC for the years 2005, 2010, 2015, and 2020 were subjected to the GIS technique. The outcomes show that there was significant conversion in agricultural land (NNP), increasing from 10.38% (2005) to 29.87% (2020) of the total study area. Furthermore, about 30.08% of unused land (CSD) and more than 10% of forest land (LNP) area were converted into agricultural land during each period. However, a large proportion of agricultural land (about 25.2%) was converted into other types of land use for the three periods. On the other hand, other types of land use coded as residential land (OTC) and built-up land (PNN) experienced large changes of about 171.66% and 245.67, and CSD exhibited a strong decrease (-99,83%) during 2005-2020 period. Several factors including climate change, international economic integration, science and technology, population growth and human resources, land resources, infrastructure, market, and policies of the local government were identified as driving forces of the LULC change in the province. Overall, it is expected that these findings will be conducive to the establishment of a general framework for land use planning in Kon Tum province.
Semiclassical asymptotic distribution of resonances created by homoclinic and heteroclinic trajectories
Authors: Fujiié Setsuro 
Published: April 2023

Here we review a part of the joint work with Jean-François Bony, Thierry Ramond and Maher Zerzeri [Astérisque 405 (2018), pp. vii+314] on the semiclassical distribution of resonances for Schrödinger operators in a complex neighborhood of a fixed energy, assuming that the trapped set of the underlying classical dynamics on the energy surface consists of hyperbolic fixed points and associated homoclinic and heteroclinic trajectories. Based on a microlocal theory of solutions near a hyperbolic fixed point established by Bony, Fujiié, Ramond, and Zerzeri [J. Funct. Anal. 252 (2007), pp. 68–125], we compute the quantization condition of resonances and prove its accuracy. We will see in particular that the principal term of the imaginary part of resonances is

Preprint Highlight: 7-UP: generating in silico CODEX from a small set of immunofluorescence markers
Authors: Zaritsky Assaf 
Published: April 2023

Multiplexed molecular imaging enables the characterization of the spatial organization of different cell types in their native tissue context but is an expensive and labor-intensive technology. This study presents 7-UP, a method that computationally generates 40 protein expression markers, at single-cell resolution, from a panel of seven experimentally measured multiplexed immunofluorescence markers. The method relies on machine learning–optimized selection of seven markers and inclusion of spatial context from the raw image that together enable reconstruction of the full protein panel. 7-UP was validated by demonstrating accurate prediction of 16 cell types and patient outcomes in head and neck cancer data sets and generalized to an unseen cancer type. 7-UP can infer rich single-cell molecular profiles from commonly available multiplexed immunofluorescence assays.

Published: April 2023

Abstract

Background
decreased muscle strength and physical function often precede disability, nursing home admission, home care use and mortality in older adults. Normative values for commonly used physical performance-based tests are not widely available for older adults but are required for clinicians and researchers to easily identify individuals with low performance.

Objective
to develop normative values for grip strength, gait speed, timed up and go, single-leg balance and five-repetition chair rise tests in a large population-based sample of Canadians aged 45–85 years.

Methods
baseline data (2011–2015) from the Canadian Longitudinal Study on Ageing was used to estimate age- and sex-specific normative values for each of the physical tests. Participants were without disability or mobility limitation (no assistance with activities of daily living or use of mobility devices).

Results
of the 25,470 participants eligible for the analyses 48.6% (n = 12,369) were female with a mean age of 58.6 ± 9.5 years. Sex-specific 5th, 10th, 20th, 50th, 80th, 90th and 95th percentile values for each physical performance-based test were estimated. Cross-validation (n = 100 repetitions) with a 30% holdout sample was used to evaluate model fit.

Conclusions
the normative values developed in this paper can be used in clinical and research settings to identify individuals with low performance relative to their peers of the same age and sex. Interventions targeting these at-risk individuals including physical activity can prevent or delay mobility disability and the resulting cascade of increasing care requirements, health care costs and mortality.
