AbstractUnderstanding propagation of scintillation light is critical for maximizing the discovery potential of next-generation liquid xenon detectors that use dual-phase time projection chamber technology. This work describes a detailed optical simulation of the DARWIN detector implemented using Chroma, a GPU-based photon tracking framework. To evaluate the framework and to explore ways of maximizing efficiency and minimizing the time of light collection, we simulate several variations of the conventional detector design. Results of these selected studies are presented. More generally, we conclude that the approach used in this work allows one to investigate alternative designs faster and in more detail than using conventional Geant4 optical simulations, making it an attractive tool to guide the development of the ultimate liquid xenon observatory.

The path integration along elliptic slices is akin to the coadjoint orbit quantization of compact Lie groups, and the calculation of the characters of elliptic group elements proceeds along the same lines as in compact groups. The computation of the trace of hyperbolic group elements in a diagonal basis as well as the calculation of the full group action on a hyperbolic basis requires considerably more technique. We determine the action of hyperbolic one-parameter subgroups of PSL

Cutting rules and positivity in finite temperature many-body theory
Authors: Hyrkäs M J , Karlsson D , van Leeuwen R 
Published: July 2022

Abstract
For a given diagrammatic approximation in many-body perturbation theory it is not guaranteed that positive observables, such as the density or the spectral function, retain their positivity. For zero-temperature systems we developed a method [2014 Phys. Rev. B
90 115134] based on so-called cutting rules for Feynman diagrams that enforces these properties diagrammatically, thus solving the problem of negative spectral densities observed for various vertex approximations. In this work we extend this method to systems at finite temperature by formulating the cutting rules in terms of retarded N-point functions, thereby simplifying earlier approaches and simultaneously solving the issue of non-vanishing vacuum diagrams that has plagued finite temperature expansions. Our approach is moreover valid for nonequilibrium systems in initial equilibrium and allows us to show that important commonly used approximations, namely the GW, second Born and T-matrix approximation, retain positive spectral functions at finite temperature. Finally we derive an analytic continuation relation between the spectral forms of retarded N-point functions and their Matsubara counterparts and a set of Feynman rules to evaluate them.

Abstract
Microplastic can highly accumulated in fresh water, sea water, sedimentary, and marine life species. Its tiny size and large quantity cause it to become ubiquitous and highly bioavailable in aquatic organism. The potential of probiotic supplement from lactic acid bacteria and Vitamin C has proven effective and beneficial in remedial process of living organisms that exposed to toxic materials in microplastic. This research wants to analyze the potential of feed supplement on morphometric and gonad weight of fish exposed to microplastics. Thirty six tilapias divided into two groups; one group given feed variant (commercial pellet, mixture of commercial pellet and probiotic, and mixture of commercial pellet and Vitamin C) and other group given microplastic concentrate variant (0; 0,1; 1; and 10 mg/L) for 15 days. The result shows changes in morphometry and the weight of fish gonad. A significant microplastic exposure reduce the size of tilapia’s morphometry (body size, standard size, head size, and body width), go nad’s weight, and tilapia’s weight. The addition of probiotics increased the morphometry of tilapia exposed to microplastics.This research will give useful informations for fish farmers in developing fish resources and fish farming.

Abstract
This study aimed to evaluate Pacific white shrimp larval quality from several shrimp breeding centers in East Java. parameters measured include 1) bolitas, 2) abundance of Vibrio spp. (water and shrimp body), and 3) muscle gut ratio (MGR). Larval samples were collected from 8 hatcheries located in East Java. The results showed that the percentage of bolitas in the hepatopancreas organ of shrimp larval in ponds 6, 7, and 8, respectively was <35%. Larval guts were found in all hatcheries, except for the 2nd pond as many as 60%. The highest abundance of Vibrio spp. (yellow colonies) in water samples and fry bodies was found in the 6th pond (26.5 × 103 CFU mL-1) and the 4th pond (76.9 × 103 CFU gr-1). The abundance of Vibrio spp. (green colony) and the highest water sample was found in the 3rd pond (3.8 × 103 CFU mL-1), while the larval was not detected. The larval found the highest percentage of MGR in the 3rd pond (87.5%), and the lowest was in the 7th pond (57.50%). Overall, our results demonstrate the infection of Vibrio spp. has involvement in the incidence of zoea syndrome in pacific white shrimp fry in hatcheries.

Published: July 2022

Abstract
Silver rasbora (Rasbora argyrotaenia) is a freshwater fishery commodity that has high economic value. However, fulfilling the demand for silver rasbora still relies on catches from nature, so cultivation is needed. The problem that occurs in the cultivation process is the Edwardsiella tarda infection which causes Edwardsiellosis disease. The purpose of this study was to determine the bacterial viability of E. tarda from silver rasbora after infection with immersion methods. The Total Plate Count (TPC) from blood, liver and kidney was taken from infected fish after 14 days immersion with bacterial suspension. The results showed that E. tarda infection had occurred in the blood, liver and kidneys as indicated by an increasing the density of bacteria in each organ along with the increasing of the concentration of infected bacteria. The highest density of E. tarda bacteria infected in silver rasbora was in the blood and the least was in the kidneys.

Abstract

Fettucine is one type of pasta that is generally made from wheat flour with a mixture of eggs and water. Wheat flour is rich in carbohydrates and low in fiber can cause obesity. One of the alternatives to overcome this problem is to increase fiber consumption by utilizing fishery commodities such as seaweed to be the main ingredient in making fettucine, namely Kappaphycus alvarezii seaweed flour. This study used experimental laboratory research methods to determine the effect of adding Kappaphycus alvarezii seaweed flour as a source of fiber to the nutritional value and organoleptic characteristics of fettucine. The design used was a completely randomized design (CRD) with one factor, consisting of 4 concentration treatments and 3 replications. The results showed that there was a significant difference between treatments (P<0.05). The highest nutritional value is obtained from the addition of 50% containing water (26,18%), ash (3,58%), protein (3,04%), fat (5,83%), fiber (3,29%), and carbohydrate (58,08%). Meanwhile, organoleptic test results with hedonic parameters showed the best treatment at the addition of 20% with an average color value (6,50%), aroma (6,77%), texture (7,17%), and taste (6,87%).
