Time and Energy Resolving Time-over-Threshold ASIC for MPPC module in TOF-PET system (ToT-ASIC2)
Authors: Orita T. , Uenomachi M. , Shimazoe K. , Ikeda H. 
Published: September 2023

Abstract
ToT-ASIC2 is a new custom front-end application specific
integrated circuit (ASIC) to readout silicon photomultiplier (SiPM)
and multi-pixel photon counter (MPPC) for time-of-flight positron
emission tomography (ToF-PET). ToT-ASIC2 is a 64-channel ASIC
fabricated using a commercial 0.25 μm CMOS process. Each
channel has an input-current buffer that sends signals to the SLOW
and FAST paths, which are used for incident radiation energy and
timing information, respectively. Time-over-Threshold (ToT) signals
from these paths are combined into one ToT signal to be output
outside the ASIC. The power consumption is approximately 2.9 mW per
channel.
This study developed a detection system comprising an MPPC with
coupled GAGG pixelated scintillators, a front-end board with
ToT-ASIC2 and ToT-DAQ. Consequently, energy and timing measurement
experiments were performed using this system to confirm the
ToT-ASIC2 energy- and timing-resolving capability. Prototype
positron emission tomography experiments with 22Na indicated an
energy resolution of 6.7% for 511 keV with the coincidence timing
resolution being 215 ps.
Investigating whether the inclusion of humid heat metrics improves estimates of AC penetration rates: a case study of Southern California
Authors: Peplinski McKenna , Kalmus Peter , Sanders Kelly T 
Published: September 2023

Abstract
Global cooling capacity is expected to triple by 2050, as rising temperatures and humidity levels intensify the heat stress that populations experience. Although air conditioning (AC) is a key adaptation tool for reducing exposure to extreme heat, we currently have a limited understanding of patterns of AC ownership. Developing high resolution estimates of AC ownership is critical for identifying communities vulnerable to extreme heat and for informing future electricity system investments as increases in cooling demand will exacerbate strain placed on aging power systems. In this study, we utilize a segmented linear regression model to identify AC ownership across Southern California by investigating the relationship between daily household electricity usage and a variety of humid heat metrics (HHMs) for ~160000 homes. We hypothesize that AC penetration rate estimates, i.e. the percentage of homes in a defined area that have AC, can be improved by considering indices that incorporate humidity as well as temperature. We run the model for each household with each unique heat metric for the years 2015 and 2016 and compare differences in AC ownership estimates at the census tract level. In total, 81% of the households were identified as having AC by at least one heat metric while 69% of the homes were determined to have AC with a consensus across all five of the heat metrics. Regression results also showed that the r
2 values for the dry bulb temperature (DBT) (0.39) regression were either comparable to or higher than the r
2 values for HHMs (0.15–0.40). Our results suggest that using a combination of heat metrics can increase confidence in AC penetration rate estimates, but using DBT alone produces similar estimates to other HHMs, which are often more difficult to access, individually. Future work should investigate these results in regions with high humidity.
The role of eddy-wind interaction in the eddy kinetic energy budget of the Agulhas retroflection region
Authors: Zhu Yanan , Li Yuanlong , Yang Yang , Wang Fan 
Published: September 2023

Abstract
The Agulhas retroflection (AR) region possesses the highest eddy kinetic energy (EKE) level in the Indian Ocean. However, mechanisms regulating EKE of the AR remain uncertain. Here, by analyzing an eddy-resolving coupled model simulation with improved EKE representation, we show that the upper-ocean EKE of the AR is mainly generated through barotropic instability in its upstream and leakage zones and is by nonlocal transport in its downstream zone. The interaction between mesoscale eddies and local winds plays a key role in EKE dissipation. The lack of eddy-wind interaction results in flawed EKE budget in the leakage zone in ocean-alone models, leading to severe biases in EKE distribution with overestimation and over-strong penetration into the South Atlantic. Our results highlight the essence of mesoscale air-sea interaction in the dynamics of the AR, with implications for understanding the inter-basin transport of the Agulhas leakage.
Uncertainty relation for non-Hermitian operators
Authors: Bagarello F 
Published: September 2023

Abstract
In this paper we discuss some aspects of the Heisenberg uncertainty relation, mostly from the point of view of non self-adjoint operators. Some equivalence results, and some refinements of the inequality, are deduced, and some relevant examples are discussed. We also begin a sort of dynamical analysis of the relation, in connection with what has been recently called γ-dynamics and γ-symmetries, and we discuss in some details the role of different scalar products in our analysis. The case of self-adjoint operators is recovered as a special case of our general settings.
The heat kernel of the asymmetric quantum Rabi model
Authors: Reyes-Bustos Cid 
Published: September 2023

Abstract
In this paper we derive an explicit formula for the heat kernel of the asymmetric quantum Rabi model, a symmetry breaking generalization of the quantum Rabi model (QRM). The method described here is the extension of a recently developed method for the heat kernel of the QRM that uses the Trotter–Kato product formula instead of path integrals or stochastic methods. In addition to the heat kernel formula, we give applications including the explicit formula for the partition function and the Weyl law for the distribution of the eigenvalues, obtained from the corresponding spectral zeta function.

Abstract
This study aims to design a route optimization model to support commodity distribution in the Moluccas archipelago zone. The model is designed using an integer programming approach for multi-depot multi-cluster with the aim of minimizing distance. In this case, several points on the island must be serviced. Each service point will only choose one port to serve. Sea transportation routes are formed from selected port nodes with a ring-ring-star hierarchical structure. A model designed to complement transportation routes in meeting the demand for service points by considering local, regional and global route distribution. Each level route will select one or more depots which will represent set to the top route level. The model is applied to several scenarios to see the best distance recommendations from island sample characteristics and point and island sizes.

Published: September 2023

Abstract
Snakehead fish (Channa striata) extract in the form of dispersion is one of the innovations in the development of snakehead fish products. Snakehead fish extract dispersion is a product in the form of a mixture of syrup (dispersion) made from snakehead fish extract raw materials, honey, and other additives. However, the syrup/dispersion products produced in previous studies have not been completely stable. This is indicated by the presence of precipitation during dispersion storage. Therefore, it is necessary to choose the right type of stabilizer to overcome this. The aims of this study were to obtain the best stabilizer for producing a stable snakehead fish extract dispersion. The method in this study was to make a dispersion of snakehead fish extract with three different stabilizers, namely xanthan gum (0.3%), carrageenan (0.1%), and carboxymethyl cellulose (CMC) (0.6%). Then we analyzed the viscosity, phase separation ratio, and redispersibility. The results showed that xanthan gum has a better level of stability than carrageenan and CMC, with a viscosity value after storage of 1, 3, 5, and 7 days, respectively 53.97 mPa.s, 51.67 mPa.s, 51.50 mPa.s, and 51.17 mPa.s. While the viscosity value of carrageenan during storage is 1, 3, 5, 7 days, respectively 5.27 mPa.s, 5.20 mPa.s, 4.90 mPa.s, and 4.50 mPa.s, and storage of CMC 1, 3, 5, and 7 days, respectively 642.67 mPa.s, 505.33 mPa.s, 452.00 mPa.s, and 297.33 mPa.s. The results of the phase separation ratio analysis showed that the stabilizers xanthan gum and CMC did not experience phase separation during storage for 1, 3, 5, and 7 days. Meanwhile, the carrageenan stabilizer at storage 1, 3, 5, and 7 days has a successive phase separation ratio of 43.81%, 40.34%, 39.47%, and 39.47%. The results of the redispersibility analysis showed that the CMC stabilizer and xanthan gum were not redispersible during storage 1, 3, 5, and 7 days. While the carrageenan stabilizer has the same redispersibility value during storage 1, 3, 5, and 7 days is one time shuffling.

Abstract
The use of organic certification benefits farmers as well as the environment. Organic coffee farmers, on the other hand, face the challenge of determining how much consumers are willing to pay for the organic coffee they produce. The purpose of this study was to investigate the factors that influence Indonesian consumers’ willingness to pay for organic coffee, as one of the indicators that influence consumer purchasing decision behavior. A structural equation model analysis was used to collect data by distributing questionnaires to a total of 766 respondents. The model was created by combining variables from the Theory of Planned Behavior and consumer awareness. This study was successful in demonstrating the direct impact of attitude, subjective norms, PBC, and consumer awareness on consumers’ willingness to pay for Indonesian organic coffee. On the other hand, health and environmental sustainability factors had an indirect influence on consumers’ willingness to pay for organic coffee. Meanwhile, regional development factors had no effect on consumers’ willingness to pay, either directly or indirectly.

Abstract
As the center of sago production, sago business in Luwu District and North Luwu District has long been the main livelihood of the local community. This study as a whole examines the linkage of the sago value chain with government intervention. The method of determining the location by purposive sampling with the consideration that Luwu District and North Luwu District are the center of sago production in South Sulawesi. The analytical method used for value chain research is chain analysis with value chain mapping from ACIAR (2012) and qualitative descriptive analysis, namely content analysis and thematic analysis. The sago value chain in Luwu District and North Luwu District involves various actors, such as farmers/producers, collectors, and retailers in the sago production and distribution process. Government intervention in this study included providing training and procurement of equipment to sago farmers. The results of this study show that government intervention only focuses on reducing the workload of sago farmers. Government intervention in this study does not directly impact other sago value chain actors, but reducing farmers’ workload can potentially have an overall positive effect by increasing the availability of sago raw materials they obtain from farmers.

Abstract
Sweet corn is popular in West Papua. This study was aimed at determining the production and chemical qualities of sweet corns using single fertilizer combination (SFC). A completely randomized design experiment was used with 5 treatments and 3 replications. The treatments were without fertilization (P0), with a concentration of P1 (22.4g/plant); P2 (23.52/plant); P3 (24.64g/plant); P4 (25.76g/plant). Variables observed were weight, length, diameter, pH, water, ash and fat content. The data obtained were analysed using analysis of variance continued with the Honest Significant Difference Test. Results showed that different concentrations gave a very significant difference (P<0.01) on cob weights (gr) (P0, P1, P2, P3, P4 were 51.39; 115.40; 133.06), cob lengths (mm) (78.45; 107.37; 113.92; 131.54;141.02), and cob diameters (mm) (24.56; 31.22; 34.29; 36.21; 37.55); did not give a significant difference (P>0.05) on pH (5.47; 5.37; 5.41; 5.40; 5.38), moisture content (%) (60.41; 60.75; 60.29; 60.08; 60.08), ash content (%) (1.95; 2.07; 2.05; 1.96; 1.92), and fat content (%) (0.62; 0.53; 0.43; 0.52; 0.40). The conclusion was that different concentrations of SFC did not give a different effect on pH, water, ash, fat content and gave a very significant difference effect on weight, length, diameter of sweet corn cobs.

Abstract
Gamma irradiation can be used to sterilize honey products. Many previous reports related to biochemical, physical characteristics and antibacterial activity on irradiated honey have not been combined into one quantitative report. Therefore, this study was conducted to determine the effects of gamma irradiation on biochemical and physical characteristics of honey. The source of data in meta-analysis study was conducted on search engines (Scopus®, PubMed®, and Google scholar®), searched with “irradiation”, “gamma”, and “honey” as keywords. Data on gamma irradiation dosage and characteristics of honey were extracted from 12 articles and 44 studies (control vs. irradiated honey). The meta-analysis results showed that gamma irradiation reduced moisture content (p < 0.01). However, gamma irradiation had no effect on viscosity, sugars, total soluble solids, and ash content. It is interesting to note that gamma irradiation significantly increased flavonoid and phenolic compounds (p < 0.01). Gamma irradiation also reduced the level of microorganism in honey (p < 0.01), as reported in total aerobic plate count variable. In summary, except for moisture and vitamin C, gamma irradiation did not influence biochemical characteristics of honey. Gamma irradiation also had no effect on viscosity as physical parameters.

Published: September 2023

Abstract
This study is aimed at measuring the color and nutrient contents of local pigmented rice from South Sulawesi. Five grams of husked rice grains are placed on a 60 mm petri dish before attaching the TES 135 colorimeter. Total protein content was measured using the Kjeldahl method. Total fat content was measured using Soxhlet. Selected varieties were analyzed further for zinc (Zn) and iron (Fe) content using Atomic Absorption. Spectroscopy. Data were analyzed using a one-way ANOVA, followed by the Duncan Multiple Range Test at 5%. The results showed that the Le’leng variety showed the lowest values of L*, a*, and b*, which means that it has the darkest color. The highest protein content is found in Le’leng and Kobo. The protein content of local pigmented rice is higher but tends to be similar in fat content to modern rice. It can be concluded that colorimetry grain color measurement follows the grains’ visual appearance. The darker the grain color, the lower the L*, a*, and b* parameters. Local pigmented rice from South Sulawesi has significant protein, fat, Fe, and Zn. Color appearance can be a preliminary visual indicator of the bioavailability of compounds with health benefits in pigmented rice..

AbstractIt is a common trait for villages surrounding conservation areas to be dependent on the forest ecosystem for food and economic needs. This is also the case for Ilomata Village, a village bordering the Bogani Nani Wartabone National Park. This research aims to identify agricultural systems, bioresources utilizations, ecological threats and the potential development of an ecologically based agricultural system in Ilomata Village, Gorontalo Province. Data were collected using in-depth interviews, participatory observations, and focus group discussions. Further, descriptive statistics are utilized to analyze the data. The result shows two forms of agriculture. First, the monoculture system is characterized by one main commodity (corn). Second, the polyculture system is characterized by a combination of crops, plantations, forestry, and livestock. For the bioresources’ utilization, as many as 79 species of vegetation were used by the community. This research also notes the forms of utilization that have the potential to threaten the ecosystem, as well as several potentials that can be developed. This research concludes that although there is an ecological-based agriculture system in Ilomata Village, it has not been implemented optimally by utilizing the existing potential. The result implies that it can be used to determine an ecologically-based agriculture intervention model.

Abstract
Chlorpyrifos is an organophosphate insecticide. It has low aqueous solubility, is volatile and non-mobile, moderately persistent in soil, highly toxic to mammals, and is an acetylcholinesterase inhibitor. The main use of chlorpyrifos is to control various types of agricultural pests. This study aims to determine the absorption of chlorpyrifos residues in maize plants. The study was conducted in July-December 2019. Experimental research was conducted at Jakenan experimental field on land contaminated with chlorpyrifos residue. The maize used was a hybrid maize variety NK 6172 Perkasa. Pesticide residue analysis was carried out at the Laboratory of the Agricultural Environmental Research Institute (IAERI). The results showed that the highest chlorpyrifos residue was in the stalks and leaf with a value of 0.0318-0.5682 mg kg−1 but still below the maximum residue limit (MRL) of 10 mg kg−1 recommended by The National Standardization Agency of Indonesia. The concentration of chlorpyriphos residue in maize grain is 0.0014-0.2203 mg kg−1 (MRL=0.05 mg kg−1). Chlorpyriphos residue in the soil is 0.0148-0.0786 mg kg−1 (MRL=3.2 mg kg−1), and the lowest was root (<0.0014 mg kg−1). Information on residue distribution on maize and soils can be helpful as an early warning about the use of insecticides and food safety measures.
