The arrival of the populist radical right in Chile
Authors: Díaz Camila , Rovira Kaltwasser Cristóbal , Zanotti Lisa 
Published: May 2023

Abstract
Despite the increasing influence of populist radical right (PRR) forces at the global level, they have been absent in
Chile until very recently. Today, however, the conditions seem to be ripe for the consolidation of the PRR in the country. As we show in
this contribution, José Antonio Kast and the Partido Republicano advance a programmatic agenda that emphasizes authoritarian, nativist, and
populist ideas. We also demonstrate certain peculiarities of this political project, which differentiates it from its European brethren. In
fact, the party has adopted very clear neoliberal positions and puts much more emphasis on outgroup distinctions within rather than outside
the nation. Moreover, given that José Antonio Kast and the Partido Republicano maintain a very fluid relationship with the mainstream right,
collaboration between the two seems much simpler and more feasible than in most European cases.
Inducing sparsity via the horseshoe prior in imaging problems
Authors: Dong Yiqiu , Pragliola Monica 
Published: May 2023

Abstract
A problem typically arising in imaging applications is the reconstruction task under sparsity constraints. A computationally efficient strategy to address this problem is to recast it in a hierarchical Bayesian framework coupled with a Maximum A Posteriori (MAP) estimation approach. More specifically, the original unknown is modeled as a conditionally Gaussian random variable with an unknown variance. Here, the expected behavior on the variance is encoded in a half-Cauchy hyperprior. The latter, coupled to the conditioned Gaussian prior, yields the horseshoe shrinkage prior, particularly popular within the statistics community and here introduced into the context of imaging problems. The arising non-convex MAP estimation problem is tackled via an alternating minimization scheme for which the global convergence to a stationary point is guaranteed. Experimental results prove that the derived hypermodel is competitive with classical variational methods as well as with other hierarchical Bayesian models typically employed for sparse recovery problems.

Published: May 2023

Abstract
Molybdenum disulfide (MoS2) has been deemed as one of the promising noble-metal-free electrocatalysts for hydrogen evolution reaction (HER), but it suffers from the inert basal plane and low electronic conductivity. Regulating the morphology of MoS2 during the synthesis on conductive substrates is a synergistic strategy for enhancing the HER performance. In this work, vertical MoS2 nanosheets were fabricated on carbon cloth (CC) using an atmospheric pressure chemical vapor deposition method. The growth process could be effectively tuned through introducing hydrogen gas during vapor deposition process, resulting in nanosheets with increased edge density. The mechanism for edge-enriching through controlling the growth atmosphere is systematically studied. The as-prepared MoS2 exhibits excellent HER activity due to the combination of optimized microstructures and coupling with CC. Our findings provide new insights to design advanced MoS2-based electrocatalysts for HER.

Abstract
An innovative divertor concept, the fish tail divertor, is proposed in this paper, aimed at reducing the surface temperature on the tokamak divertor plate as well as that due to the edge localized modes. This new concept has been implemented in experiments to demonstrate its capability of strike point sweeping on the plate at a frequency range from 10 to 100 Hz by using an oscillating magnetic field. A strike point movement of 5–6 cm is achieved by applying a coil current of several percent of plasma current, leading to a significant reduction of divertor surface temperature. The result indicates a possible application in a fusion reactor.

Landscape vulnerability assessment driven by drought and precipitation anomalies in sub-Saharan Africa
Authors: Guo Xinya , Zhang Zhenke , Zhang Xingqi , Bi Mo , Das Priyanko 
Published: May 2023

Abstract
Global climate extremes are increasingly frequent and intense, especially in Africa, which is most vulnerable to climate change (de Sherbinin 2013 Clim. Change 123 23–37). However, the vulnerability of the landscapes composed of diverse ecosystems to climate extremes is far from being clearly understood. This study constructed a set of index systems based on the ‘exposure-sensitivity-adaptive capacity’ framework to assess landscape vulnerability driven by abnormal drought and precipitation in sub-Saharan Africa. In addition, correlation analysis was used to discover factors affecting landscape vulnerability. The results showed that a high level of landscape vulnerability was determined by high exposure and high sensitivity, as adaptive capacity exhibited little difference. The drought and wet events occurred in 80.9% and 51.3% of the climate change-dominated areas during 2001–2020, respectively. In areas where drought anomalies occur, about 8% of the landscapes, primarily formed by sparse vegetation and grasslands, were susceptible to drought. Moreover, in areas with abnormal precipitation, high vulnerability occurred only in about 0.6% of landscapes mostly covered by grasslands and shrubs. In addition, the intensity of landscape vulnerability driven by drought was higher than that driven by precipitation anomalies in the areas that experienced both dry and wet anomalies. Furthermore, the greater the deviation of landscape richness, diversity, and evenness from the normal climate state, the stronger the landscape vulnerability. The results add new evidence for landscape instabilities—an obvious contrast driven by drought and wetness—from the perspective of landscape vulnerability. The methodology of assessing landscape vulnerability established in this study can provide a new way to guide the regulation of landscape composition in response to frequent climate extremes on a macro level.
Relieving nematic geometric frustration in the plane
Authors: Pedrini Andrea , Virga Epifanio G 
Published: May 2023

Abstract
Frustration in nematic-ordered media (endowed with a director field) is treated in a purely geometric fashion in a flat, two-dimensional space. We recall the definition of quasi-uniform distortions and envision these as viable ways to relieve director fields prescribed on either a straight line or the unit circle. We prove that using a planar spiral is the only way to fill the whole plane with a quasi-uniform distortion. Apart from that, all relieving quasi-uniform distortions can at most be defined in a half-plane; however, in a generic sense, they are all asymptotically spirals.

However, it may serve as a cornerstone of full quantum computation. As to its group structure it is well-known that—in N-dimensional quantum mechanics—the Clifford group is a natural semidirect product provided the dimension N is an odd number. For even N special results on the Clifford groups are scattered in the mathematical literature, but they mostly do not concern the semidirect structure. Using appropriate group presentation of

Published: May 2023

Abstract
The drop in global rubber prices worsens farmer-level rubber selling prices, affecting rubber farmers’ economics. One of the efforts to develop the farmer’s economy is strengthening rubber farmers’ institutional aspects. This study will examine institutional strengthening to stabilize rubber prices at the farmer level and increase farmers’ negotiating power. This study employs a qualitative case study methodology. Data were descriptively examined. The findings of this study explain that the rubber prices decline in rubber farmers’ economies does not improve from time to time. The decline in rubber prices resulted in land conversion, decreased production, and fewer rubber farmers. On the other hand, rubber marketing institutions have improved rubber farmers’ price stability bargaining position and increased rubber farmers’ economy. This research implies that rubber marketing institutions through farmer associations can increase farmers’ bargaining position, maintain rubber price stability and contribute to the empowerment of rubber farmer commodity institutions.
“Act-design-plan-locally” for built environment studies: an approach towards reaching sustainable development goals
Authors: Saputra Kadek Edi , Suartika Gusti Ayu Made 
Published: May 2023

Abstract
This paper departs from the view that reorienting higher education in the built environment field towards implementing “act-design-plan-locally” principles is a step closer to an awareness of Sustainable Development Goals. It embraces the concept of ‘vernacularity’ that promotes strategies in partnering with nature, valuing simplicity and humility as an approach to learning resources. The idea has been introduced as part of various subjects offered in academic curricula, particularly those practised in many architecture programs. On the other hand, taking it as a learning approach has not been considered. Two principles are significant. Firstly, this paper takes the concept further and offers a theoretical insight into how the ‘act-design-plan-locally’ principle inspired by vernacularly can be embedded in the learning process of built environment studies. In so doing, it first provides an understanding of the principle itself, especially its potential position to support efforts in achieving sustainable development goals. Second, it explores prospects that enable the inclusion of this principle into the higher education teaching and learning process, as well as challenging circumstances that dissuade the achievement of this objective. Here, we categorize discussion regarding academic environmental systems, teaching environments, available resources and behavioural mandates. The whole discussion will be concluded in the third part of this paper.
Phosphorus Uptake of Oil Palm Leaves on the Axillary Application of Diammonium Phosphate Fertilizer
Authors: Arifin Muhamad Amin , Mildaryani Warmanti , Swasono Didit Heru 
Published: May 2023

AbstractFertilization costs for almost all oil palm plantation companies range from 40-60% of the total plant maintenance costs. Farm fertilizer consumption and world fertilizer prices for the three main macronutrients increase yearly, but the use efficiency is low. Meanwhile, pressure came from environmentalists regarding the effects of pollution by excessive use of fertilizers. Application of fertilization through axillary oil palm midrib is expected to overcome inefficiency. This study examined the phosphorus uptake of three-year-old oil palm leaves on the application of diammonium phosphate fertilizer through two positions of the axil, the top and bottom, with four dosage levels, namely 200. 250. 300 and 350 grams per tree. The split-plot design method was used in the research conducted at PT Bumitama Gunajaya Agro oil palm plantation, West Kalimantan. The results showed that Phosphorus uptake was relatively the same in all leaf axil positions and doses and control with the highest dose of 350g/tree through the soil. The results indicate that fertilization of oil palm is possible to do through any axils with a lower amount than it through the soil.

Published: May 2023

Abstract
Potato is a horticultural commodity with good prospects for development. Potato tissue culture technology is one of the efforts to produce virus- and disease-free potato seeds. The aim of this experiment was to see if there was an interaction between the administration of multiple coumarin concentrations and the number of nodes and at what concentration of coumarin and at what number of nodes gives optimal results for induction of potato micro tuber. This experiment was arranged according to a two-factor factorial Completely Randomized Design with 3 replications. The 1st factor was multiple coumarin concentrations with 4 levels (30, 60, 90, 120 mg/l) and the 2nd factor was the number of nodes with 3 levels (1 node, 2 nodes, and 3 nodes). The results showed that there was an interaction between the administration of multiple concentrations of coumarin and the number of nodes, showing the best interaction when the coumarin concentration was 120 mg/l with 2 nodes that could form tubers with a percentage of 94.44%. The 120 mg/l coumarin concentration gave the highest of plantlets forming micro-tubers, the highest number of micro tuber and the largest micro-tuber diameter. The two-node treatment increased the percentage of plantlets forming micro tubers, the number of micro tubers, and the diameter of the micro tuber.

Published: May 2023

Abstract
Plant Growth Regulators and photoperiods will affect callus morphogenesis from garlic bulbils. The study aimed to obtain the best interaction between media composition and photoperiod for shoots and root induction of the garlic callus. The research has two-stage. The first stage consisted of two factors. The first factor is the combination of PGR for shoots induction which consists of three combinations, i.e., 0.1 ppm NAA + 1 ppm BAP, 2 ppm NAA + 2 ppm BAP, and 0.4 ppm 2,4-D + 2 ppm kinetin. The second factor is photoperiod which consists of 10, 16, and 22-h light conditions. The second stage is the root induction in different PGRs (2 ppm IBA and 0.2 ppm NAA + 2.25 ppm BA) under continuous dark conditions. The results of the first stage showed that the PGR produced the most shoots was 0.1 ppm NAA + 1 ppm BAP. After four weeks, the frequency of an explant emerging during the shoot reached 64% on media 0.1 ppm NAA + 1 ppm BAP. The treatment MS media supplemented with 0.1 ppm NAA + 1 ppm BAP at 16-h photoperiods increased the growth of shoots per explant in 11-15 shoots and produced the most extended shoot length. The result of the second stage showed that the number of roots on 2 ppm IBA is the same as NAA 0,2 ppm + BA 2,25 ppm, but the treatment 2 ppm IBA has the highest root number in three months.

Published: May 2023

Abstract
This research examined the variation in concentration of protein derived from jack bean throughout mold fermentation and the distribution of the molecular weight (MW) of the resultant peptides. In addition, the effects of peptide size on ACE inhibitory action were investigated. The jack bean was soaked and boiled before fermentation, then inoculated using 0.2% of commercial tempe inoculum. Furthermore, the inoculated seeds were incubated at room temperature for 48 h (T48), and 72 h (T72), and unfermented jack bean (T0) was used as a control. The total protein, soluble protein, MW distribution of peptides, and ACE inhibitory action were all examined. The results demonstrated that the concentration of soluble proteins rose as fermentation duration increased (p < 0.05). Meanwhile, the total crude protein in all samples did not change significantly (p > 0.05). The resultant peptides were then separated by dialysis to generate four peptide fractions, namely; fractions A (MW of <1 kDa), B (MW of 1-3.5 kDa), C (MW of 3.5-14 kDa), and D (MW of > 14 kDa). The peptide fractions of the three samples demonstrated that the number of peptides in fraction D decreased significantly during the fermentation, followed by an increase in peptide fractions with smaller MW (Fractions A, B, and C). The number of peptides in fraction A of T0, T48, and T72 was 9.51; 49.87; and 56.31%, respectively. The more significant amount of smaller peptides indicated a higher possibility to have the capacity to inhibit ACE. Fractions A, B, C, and D of T72 exhibited ACE inhibitory action with the value of 83.21; 62.53; 61.07; and 49.64%, respectively. In this investigation, the ACE inhibitory action was stronger as the MW of the peptides decreased. Fraction A had the greatest inhibitory action with an IC50 of 0.60 mg/mL. In conclusion, the fermentation duration enhanced the concentration of soluble protein. Consequently, jack bean protein degraded into various sizes of peptides during fermentation. Furthermore, the smallest size of peptides fraction demonstrated the best ACE inhibitory activity.

Abstract
Diabetes mellitus (DM) is a disease caused due to high blood sugar levels. Treatment for Diabetes mellitus patients can be supported through a suitable diet and nutrition intake. One of the potential plants used in a diabetic diet is pumpkin (Cucurbita moschata) which contains numerous bioactive compounds such as fiber, beta-carotene, and phenolic compounds. This study was conducted to determine the effect of substitution feeding of pre-treated pumpkin flour, i.e., blanching (90°C, 6 min) or soaking under citric acid solution (0.1%, 60 min), on blood glucose levels of hyperglycemic male Wistar rats. The pre-treatment of results showed that the feeding substitution of 25% pre-treated pumpkin flour had reduced the blood glucose level of the hyperglycemic male Wistar rats group. The highest blood glucose reduction of 23.26% or 45.22 mg/dL was found in the rats fed with the substitution of 25% pumpkin flour treated with citric acid.

Abstract
The purpose of this research was to manufacture smart packaging made from pH color indicators Methyl Orange (MO), Methyl Red (MR), and Bromocressol Green (BCG) and analyze the best indicators in responding to the decline of quality fillet of Pangasius spp. Sensitivity indicators were tested with simulated gas amin issued by NH4OH for 30 minutes. They tested the color change of indicator in field trials conducted with sensitivity to the decline of quality fillet fish Pangasius sp. every 3 hours for 15 hours. Further tests were done on the fish to find the time of fish freshness with the pH, TPC, and organoleptic (SNI 2346:2006). The research results showed that all indicators could be used as packaging materials for smart packaging that decline the quality of pangasius sp. indicator made of BCG responds better than the others. Test results of testing indicators sensitivity with NH4OH showed that all indicators could be used as indicators. The results of testing the sensitivity indicator against the decline of the quality of the pangasius sp. fillets showed that the limit of the freshness of the fish used in this research is over 6th hours to 9th hour of storage where at the 9th, the color of the indicator changed, MO from pink to yellowish-orange, MM from deep red to yellowish-orange and BCG from pale yellow to blue. At 9 hours of storage, the results of RGB of MO, MR, and BCG are 190.00±0.46, 165.07±0.78 and 0.70±238.04 accordance with the decline of the quality of the fish assessed from the test results of pH value (7.54), TPC (5.74 X 10 6) and the organoleptic value of appearance (5.0), smell (4.5) and texture (5.0). In conclusion, indicators made of MO, MR, and BCG can be used as smart packaging to detect the deterioration of Pangasius sp., and indicators made of BCG can respond better than indicators of MO and MR.
