NEXT-White results and roadmap towards a ton-scale detector
Authors: Novella Pau 
Published: June 2023

Abstract
The goal of the NEXT collaboration is the sensitive search of the neutrinoless double beta decay of 136Xe at the Laboratorio Subterráneo de Canfranc. A first large-scale prototype of a high-pressure gas-Xenon electroluminescent TPC, NEXT-White, was operated from 2016 to 2021. This 4–kg radiopure detector has proven the outstanding performance of the NEXT technology in terms of the energy resolution (<1% FWHM at 2.6 MeV) and the topology-based background rejection. After measuring the relevant backgrounds and their spatial origin, the NEXT-White data collected with 136Xe-enriched and 136Xe-depleted gas have been used to perform a measurement of the two-neutrino mode of the double beta decay. A novel technique based on a direct background subtraction yields a half-life of

. This result is consistent with the half-life derived from a background-model-dependent approach. Scaling the technological solutions of NEXT-White, the NEXT-100 detector is being constructed during 2022 and will start the physics data taking in 2023. Holding 100 kg of 136Xe and with a background index below 5×10−4 counts/keV/kg/year, NEXT-100 will perform the first competitive search for the neutrinoless double beta decay within the NEXT roadmap. After 3 years of data taking, a sensitivity to the half-life of 6×1025 yr at 90% C.L. will be achieved. The design for a future ton-scale detector, NEXT-HD, is being carried out in paralel. Operating with low-difussion gas mixtures and a reduced background budget, NEXT-HD will reach sensitivities above 1027 yr. A promising R&D line aims at eventually equiping the NEXT techonlogy with 136Ba-tagging capabilities, opening the doors for a truly background-free experiment.

Published: June 2023

Abstract
Physics continues to be an inexhaustible source of problems that have inspired the theoretical development of mathematics, particularly in the development of the theory of dynamical systems that have their origin in the physics of the 15th century, with the beginning of differential calculus by Newton and Leibniz; differential equations are an appropriate tool for research in different areas of knowledge. Our objective is to show an example of how we can use dynamical systems in a problem framed in forestry and agricultural systems, ecology, and epidemiology. This work is inspired by one of the essential primary crops in the energy intake of the human diet, wheat; as it turns out, the productivity of this food can be affected by several biotic stresses, including viral diseases and their associated vectors. Among the viral infections is the barley yellow dwarf virus, which causes 11% to 33% yield losses in wheat fields; the virus moves through the agricultural landscape via different aphid species (vectors). The main problem is that aphids prefer colonizing plants with the virus, causing rapid growth of infected plants and substantially decreasing crop productivity; therefore, we propose to study the dynamics of aphid-plant interaction, in which the impact of aphid preference for infected plants is determined, and we obtained as a result that a key parameter is the quantity and quality of food consumed by aphids.

Enhanced adsorption of chlorogenic acid polyphenol by layered double hydroxide modified with sodium dodecyl sulfate
Authors: Nascimento A C A , Ruellas T M O , Malafatti J O D , Paris E C 
Published: June 2023

Abstract
Polyphenols are a class of organic contaminants highly present in wastewater from industrial and agro-industrial processes. Adsorptive processes are employed to remove contaminants from effluents without the generation of by-products. Among the challenges in removal is the search for adsorbents that have affinity and favor the interaction with the contaminant. In this sense, this paper aimed to evaluate a layered double hydroxide modified with sodium dodecyl sulfate as an adsorbent material of the chlorogenic acid polyphenol. Carbonated magnesium-aluminum hydrotalcite was the layered double hydroxide employed for modification at different sodium dodecyl sulfate contents. The results showed that the modification with 50% w w-1 sodium dodecyl sulfate increased the adsorptive capacity of the modified layered double hydroxide from 0.030 mg g-1 to 2.3 mg g-1 after 24 hours of contact with the polyphenol. Thus, the use of sodium dodecyl sulfate for surface modification of layered double hydroxide indicated positive results that favor the application of the modified material in the removal of polyphenols.

To do this, doctors and engineers generate test anatomical models to study and simulate the operative approach, surgical cutting guides to reduce the time of the intervention, and the bone implant itself to correct or overcome certain pathologies. In all the cases treated, the physical and mechanical properties of the structure, bone or not, replaced or studied, have been taken into account.
Modeling a quasi-passive bipedal walker: when and where to kick
Authors: Clavijo J , Sierra W , Sánchez S 
Published: June 2023

Abstract
Walking is one of the most complex tasks a human being can perform. It takes several years to develop the patterns that enable a person to walk and run. Although it is now possible to replicate these patterns in machines such as robots, actuators are needed to control the pace and compensate for the energy loss of walking. However, in small robots (in the scale of centimeters) the size and weight of the actuators could be a limiting factor for their use. To solve this problem, quasi-passive walkers have been recently proposed. These walkers consist of several coupled rigid bodies, usually forming a biped, that move on flat surfaces in the presence of a gravitational field. It is well known that these bipeds can descend on small slope planes without the need for actuators. Walking on horizontal planes requires the presence of actuators to initiate and maintain the pace, however, these actuators could be small enough to ”kick” the walker at the right point at the right time. In this work, we present a physical-mathematical model of a bipedal walker composed of five rigid bodies (two legs, two feet, and the hip) moving in a horizontal plane. The model focuses on the natural motion of the biped under certain initial conditions with the ultimate goal of determining the best position of the actuators and the actuation time to maintain the gait. This model could be used as a guide for the construction of small laboratory-scale walkers and as a teaching tool in biomedical engineering courses.
Quantum battery charging by non-equilibrium steady-state currents
Authors: Kamin F H , Abuali Z , Ness H , Salimi S 
Published: June 2023

Abstract
We present an analysis of the availability and maximum extractable work of quantum batteries (QBs) in the presence of charge and/or heat steady-state currents. QBs are modeled as non-interacting open quantum systems (mesoscopic systems) strongly coupled to two thermal and particle reservoirs within the framework of non-equilibrium Green’s function theory in a steady-state regime. We found that the battery can be charged manifestly by a steady-state charge current compared to heat one, especially, in an off-resonant transport regime. It allows us to reliably access the performance of the QBs in the high bias-charging regime.
Graph theory approach to exceptional points in wave scattering
Authors: Scali Stefano , Anders Janet , Horsley Simon A R 
Published: June 2023

Abstract
In this paper, we use graph theory to solve wave scattering problems in the discrete dipole approximation. As a key result of this work, in the presence of active scatterers, we present a systematic method to find arbitrary large-order zero eigenvalue exceptional points (EPs). This is achieved by solving a set of non-linear equations that we interpret, in a graph theory picture, as vanishing sums of scattering events. We then show how the total field of the system responds to parameter perturbations at the EP. Finally, we investigate the sensitivity of the power output to imaginary perturbation in the design frequency. This perturbation can be employed to trade sensitivity for a different dissipation balance of the system. The purpose of the results of this paper is manifold. On the one hand, we aim to shed light on the link between graph theory and wave scattering. On the other hand, the results of this paper find application in all those settings where zero eigenvalue EPs play a unique role like in coherent perfect absorption structures.

Published: June 2023

Abstract
The western area of Lombok Island is a tourist area that has rich underwater biodiversity in coral reefs ecosystem because of the flow path of Indonesia Trough Flow which carries nutrients continuously through the Lombok Strait. Damage that occurs around the Western area of Lombok Island is caused by climate change and community waste disposal activities that cause coral bleaching. An increase of 1.23°C Sea Surface Temperature occurred in Sekotong on February 2016 and leads to the coral bleaching event on the area. The research was conducted by using the underwater photo transect method and the photos processed by CPCe program shows mass coral bleaching impacted coral condition in West Lombok. Live coral cover was decreased 2.74% comparing with last live coral cover. Total colonies were impacted by coral bleaching 40.04% in Gili Tangkong and 43.63% in Gili Asahan. This Study shows that each species survives and be able to be broodstock for the next life of corals in these areas.

Abstract
Stingrays are a resource that is vulnerable to overfishing and habitat degradation. The research was conducted to obtain data and information that is still lacking and much needed for the utilization and protection of stingrays, including; life history, stomach contents, and nursery ground. The study was conducted in October - November 2018 by exploratory, including taking stingrays by trawling and measuring habitat conditions with Conductivity, Temperature, and Depth. The results showed a total stingrays are 744 individuals, weighing 2,986.6 kg and 24 species. Individual stingrays have a width disc range of 9-134 cm and a weight of 20-67000 g. The growth pattern of stingrays is generally allometric, except for Gymnura zonura. The average value of the relative condition factors is generally >1, except for Aetomylaeus maculatus and Brevitrygon walga. Stingrays have an unbalanced sex ratio, gonads consist of 43% adolescent and 57% mature, and the number of neonates is 1-6 /parent. The correlation between clasper length and disc width is generally positive, except for Hemitrygon longicauda. Of the stomach contents of all stingray species, 64 % is shrimp, Himantura leoparda which have various prey. The area east of Aru and west of Papua are the locations used as nursery grounds by most various stingrays. Nursery grounds of Stingray is generally shallow coastal areas with low oxygen, eutrophic and high turbidity. The results of this study are expected to be used as a basis for managing stingray resources in the Arafura Sea and further research is recommended to be carried out in four different seasons.

Published: June 2023

Abstract
The Sangihe Islands is located in the Republic of Indonesia Fisheries Management Area (WPPNRI) 716, which has an area of about 52.5 million hectares. The potential productions for small and large pelagic fish in WPP NRI 716 are 332,635 tons/year and 181,491 tons/year, respectively, with utilization rates of 0.48 and 0.63. The dominant fish species caught were skipjack, mackerel, yellowfin tuna, and anchovies. In order to estimate fish biomass around the Sangihe Islands waters, acoustic data has been collected in several locations using a 120 kHz BIOSONIC DT-X echo sounder mounted on fishing vessels with purse seine gear. In addition, an analysis of the data from the results of the Spatial Ecosystem and Population Dynamics Model (SEAPODYM) from INDESO Project was also carried out. This model has a resolution of 1/12° and applied in Indonesian waters for 3 types of tuna, namely yellowfin, bigeye, and skipjack. Acoustic data showed that the largest fish biomass along the survey tracks was found at depths between 126 and 150 m, with a total biomass of 21,418 tons. Meanwhile, from the model results, it was found that skipjack biomass was the largest. The average biomass around the Sangihe Islands waters was around 1,340 tons.

Abstract
The Monitoring of Indonesia Throughflow (MITF) with scientific cruise across the Indonesian waters that are connecting the islands of Kalimantan and Sulawesi or strait of Makassar. This cruise carried out in August 2015 in an area between 2° and 4° South and 118° and 119° East. This cruise aims to characterize the concentration of nutrients and abundance of phytoplankton groups as well as explain their distribution based on the environmental conditions. Nutrient concentrations consisting of Inorganic Dissolved Nitrogen (DIN), Inorganic Dissolved Phosphate (DIP) and Inorganic Dissolved Silicate (DSi) were measured at seven depth layers, i.e. 10, 30-60, 100-150, 300, 500, 750 and 1000 meters. The study showed that in the transitional season (August), the upper layer of study sites were characterized by salinity between 34.05 and 34.76 PSU, temperature between 26.85 and 29.88 °C, and relatively high nutrient concentration, i.e. DIN = 8.91 - 36.74 μM, DIP = 0.02 - 0.16 μM, and DSi= 31.88 - 249.49 μM. The phytoplankton community groups found were Cyanophyta, Bacillariophyta (Diatom), and Dinophyta, where the highest abundance was Cynophyta for the genus Trichodesmium sp. The composition of phytoplankton community in the surface layer is strongly influenced by sea surface temperature, salinity and nutrient concentration. We found that nutrient utilization in the surface layer is relatively high.

Authors: Pitriana P , Radjab A W , Basit A 
Published: June 2023

Abstract
Many deep-sea scientific discoveries have been driven by sampling from mooring systems. We observed biofouling assemblages on five mooring systems in the Talaud Sea and the Halmahera Sea. Biofoulings on all the mooring components extending from the sea surface to the depth of 1800–2000 m were documented. We found mollusks, barnacles, annelids, algae, and sponges assemblages on buoys, instruments, and cables of the mooring systems. Barnacle Heteralepas sp. was the most dominant biofouling attached to the float instruments of all mooring systems. At a depth of 200 m, we found mollusks, barnacles, and sponges; while algae were founded at a depth of 750 m, 1000 m, 1200 m, and 1800 m. In comparison, sponges were detected at a depth of 200 m, 250 m, 500 m, 750 m, 1000 m, 1200 m, and 1800 m. Nevertheless, at a depth of 2000 m, we did not find any biofouling attached to the mooring systems.

Published: June 2023

Abstract
Polluted water, floods, and inefficient irrigation water distribution system are the main issues of water system conditions of Indonesia especially in peripheral urban areas. In those areas, because of the rapid increased of land prices, the occurrences of small residential areas are massive replacing the existence of productive rice fields. Not only land conversion and mixed land use have been the results, the mix function is also experienced in water system between drainage system and irrigation water system in those areas. Taken Sukoharjo Regency in Central Java Indonesia as a case study, the study is aimed to investigate the integration between irrigation and drainage water system. To trace that, we undertook three analyses: 1) comparing the physical layout of both water system in practices; 2) collating and analysing Indonesia regulations on irrigation and drainage system; 3) analysing the association between 1) and 2). We identified why there is an overlap or intertwined function in the practices. This was done by elaborating the discrepancies and incompatibility through the content analysis of the regulations. The study reveals that the mix function between drainage system and irrigation water system happened because there is dualism in their regulations. This is crucial to coordinate between the provision of drainage system and irrigation water system in Indonesia regulations to prevent the occurrence of intertwined problems and steer water system management toward sustainable condition.
The Influence of Density and Mixed Land Use on The Spread of Covid-19 in Surakarta City
Authors: Istanabi T , Miladan N , Werdiningtyas RR 
Published: June 2023

Abstract
Covid-19 has a significant risk of spreading in urban areas because of the aglomeration of built-up areas and people. It frequently contains a mix of land uses and is accessible to urban amenities. Due to the area’s extensive usage of mixed land uses, it is better able to provide internal urban services on its own. Greater use of area lockdown and social separation strategies could result from this situation. The most populous city in the province of Central Java, Surakarta, has a significant risk of contracting COVID-19. The purpose of this study is to evaluate the impact of density and levels of mixed land use on the Covid-19 distribution in Surakarta City.Population density is used to calculate density. The entropy index approach was used to measure the amount of mixed land use. It is a method for calculating the balance between each form of land use. The availability of current land use data being processed by the spatial analysis with the Arc GIS application provided help for the analysis. Additionally, it makes use of information on Covid-19 cases in relation to the general populace that is supplied by the Surakarta Municipality. The relationship between mixed land use and Covid-19 risk was analyzed using a linear regression approach. The study’s findings indicated a minor influence between density and the spread of COVID-19. Meanwhile, the level of mixed land use does not influence the spread of the Covid-19 virus in Surakarta City.
