Published: July 2023

Abstract
With the rapid development of modern society, environmental pollution is increasingly serious, among which noise pollution has become the world’s three major. At present, the methods to solve the noise problem are becoming more and more diverse. Among them, the use of porous materials for sound absorption and noise reduction is still one of the most important ways. Open-cell aluminum foam has high manufacturing costs and limited application scenarios. Therefore, some scholars have studied low-cost closed-cell aluminum foam, hoping to improve its sound absorption coefficient. Closed-cell aluminum foam is mainly used in sound insulation and has little sound absorption ability. For improving closed-cell aluminum foam sound absorption property, some scholars have researched the influence of mechanical perforation on the acoustic property of aluminum foam, but the sound absorption potential of small holes cannot be played due to the large aperture made during the process. Therefore, this paper designs and processes different aluminum foam sound absorption structures based on high-speed EDM technology and studies the effect of perforation aperture, perforation depth, and perforation rate on sound absorption peak value and sound absorption coefficient in low and middle-frequency bands (250HZ-2000Hz).

Published: July 2023

Abstract
The simulation and corrosion conduction of anti-acid brick in high temperature and particle abrasion circumstances were tested with scanning electron microscopic, mechanical compression, and X-ray diffraction. The results showed the strength degradation rates of the Anti-acid brick were 7.0% and 17.8% in different high-temperature and acid corrosion conditions. The high-temperature water vapor in the environment permeated into the brick after eroding the crystal structure of the brick surface. The structural strength of the silicate anti-corrosion bricks would be reduced under the continuous impact of solid particles. The corrosive products dissolved in the slurry solution and ran off the matrix. With the constant corrosion of the hydrochloric acid solution, the corrosion formed large holes in the interior of the depression area, which aggravated the strength reduction of the brick material.

Authors: Tilly E. , Handley M. 
Published: July 2023

Abstract
We demonstrate three-dimensional track reconstruction of
electrons in a low pressure (50 Torr) optical TPC consisting of two
glass GEMs with an ITO strip readout in CF4 and CF4/Ar
mixtures. The reconstructed tracks show a variety of event
topologies, including short tracks from photoelectrons induced by
55Fe 5.9 keV X-rays and long tracks from gamma ray
interactions and beta decays. Algorithms for event identification
and track ridge detection are discussed as well as multiple methods
for integrating information from the camera image and ITO waveforms
with the goal of full 3D reconstruction of the track.
Exact results of dynamical structure factor of Lieb–Liniger model
Authors: Li Run-Tian , Cheng Song , Chen Yang-Yang , Guan Xi-Wen 
Published: July 2023

Abstract
The dynamical structure factor (DSF) represents a measure of dynamical density–density correlations in a quantum many-body system. Due to the complexity of many-body correlations and quantum fluctuations in a system of an infinitely large Hilbert space, such kind of dynamical correlations often impose a big theoretical challenge. For one-dimensional (1D) quantum many-body systems, qualitative predictions of dynamical response functions are usually carried out by using the Tomonaga–
Luttinger liquid (TLL) theory. In this scenario, a precise evaluation of the DSF for a 1D quantum system with arbitrary interaction strength remains a formidable task. In this paper, we use the form factor approach based on algebraic Bethe ansatz theory to calculate precisely the DSF of Lieb–Liniger model with an arbitrary interaction strength at a large scale of particle number. We find that the DSF for a system as large as 2000 particles enables us to depict precisely its line-shape from which the power-law singularity with corresponding exponents in the vicinities of spectral thresholds naturally emerge. It should be noted that, the advantage of our algorithm promises an access to the threshold behavior of dynamical correlation functions, further confirming the validity of nonlinear TLL theory besides Kitanine et al (2012 J. Stat. Mech. P09001). Finally we discuss a comparison of results with the results from the ABACUS method by J-S Caux (2009 J. Math. Phys.
50 095214) as well as from the strongly coupling expansion by Brand and Cherny (2005 Phys. Rev. A 72 033619).
Modified saddle-point method applied to direct ionization of noble gas atoms
Authors: Jašarević A S , Hasović E , Milošević D B 
Published: July 2023

Abstract
When exposed to strong laser fields, atoms or molecules can absorb more photons from the laser field than is necessary for ionization. This process is called above-threshold ionization (ATI). In analyzing this process, the strong-field approximation (SFA) turns out to be a very useful theoretical tool. In the SFA the differential ionization rate, which is an observable quantity, can be expressed as an integral over the ionization time and can be calculated by numerical integration (NI) or using the saddle-point method (SPM). When we use the Slater orbitals to describe the ground-state wave function of the valence electron, the results obtained using the SPM and NI do not agree. We find the reasons for this disagreement and introduce a modified SPM that leads to excellent agreement between the SPM and NI results for various strong laser fields.

Published: July 2023

Abstract
Kwatisore waters in the Cenderawasih Bay National Park area is one of the whale sharks’ habitats in Indonesia. As shark sightings seem to occur daily there is the opportunity for ecotourism development in the area. This study aims to quantify the occurrence of whale sharks at Kwatisore, and estimate the carrying capacity of the area, together with its suitability for ecotourism based on whale shark aggregations. Primary data collection on the appearance of whale sharks was carried out every day through a census technique on 7 designated areas (Apr to Aug, 2022). Every whale shark that appears on the surface of the water is photographed and identified by an ID number based on the I3Sv2.0 and its sex determined. During the census period, 709 whale sharks’ sightings were recorded mostly in the morning. There were 15 individuals in total, all males with a total length ranging from 3-7 m. The carrying capacity of the area for whale shark ecotourism in Kwatisore waters is a maximum of 252 people per day who are allowed to interact with whale sharks, while the tourism suitability index is included in the very appropriate category for whale shark tourism.

Abstract
Marine debris is a serious problem around the world. The entry of garbage into the sea not only threatens the survival of various marine organisms but also disturbs fishing activities, thereby reducing fishermen’s production and income. This study aimed to identify the fishing gear damaged by marine debris during fishing operations and analyze how much the marine debris impacted the production of various fishing units. Data were obtained from 101 fishermen operating at Ambon Bay by observation, interview, and descriptive analysis. Obstacles by the trash during fishing operations are among the trash twisted or attached to fishing gear; trash are twisted at the propeller of the boat and damage the fishing gear. On the fishing line group, the main hurdle is on the vertical hand line, where the trash are entangled at the hook; on the gill net group, the main hurdle is on the bottom gill net, where the trash are twisted to body net; and on the seine group, the main constraint is on the beach seine, where the trash are trapped in the cod end. This condition causes a decline in production, with the biggest impact on the bottom gill net, with a decrease in production of 4.38% from the average production per trip.

Abstract
Ambon has problems with plastic pollution, both in the rivers and the bay. Due to faults in the waste system, 60 tons of waste is not collected in Kota Ambon. This waste ends up in illegal landfills, the waste is burned or thrown in the water. The plastic pollution in the bay contributes to the global problem of plastic soup. Research was conducted based on question; which recommendations can be given to collect the floating plastics in the rivers around Ambon Market by using the litter traps. To answer the main question, sub-questions are drafted covering the sources of pollution, possible locations, and the possibilities for a trap. The research is conducted using different methods that is interview to local experts, observation, literature research and talks to residents. Most of the plastic found are single-use plastics, like water and food packaging materials. The most feasible location for a litter trap is the end of Batu Merah River due to the abundance of plastic, the depth, and the nearby presence of Speed Sampah. The concept litter trap showed that this device could be effective at Batu Merah River. Further research is needed to create a more definitive solution for plastic pollution. Several aspects must be taken into account, such as the circumstances like the rainy season, sedimentation, current, and tide can impact the working of the litter trap and should be considered during the designing process.

Published: July 2023

Abstract
Lithium–sulfur (Li–S) batteries are considered as promising candidates for future-generation energy storage systems due to their prominent theoretical energy density. However, their application is still hindered by several critical issues, e.g., the low conductivity of sulfur species, the shuttling effects of soluble lithium polysulfides, volumetric expansion, sluggish redox kinetics, and uncontrollable Li dendritic formation. Considerable research efforts have been devoted to breaking through the obstacles that are preventing Li–S batteries from realizing practical application. Recently, benefiting from the no additives/binders, buffer of volume change, high sulfur loading and suppression of lithium dendrites, nanoarray (NA) structures have have emerged as efficient and durable electrodes in Li–S batteries. In this work, recent advances in the design, synthesis and application of NA structures in Li–S batteries are reviewed. First, the multifunctional merits and typical synthetic strategies of employing NA structure electrodes for Li–S batteries are outlined. Second, the applications of NA structures in Li–S batteries are discussed comprehensively. Finally, the challenge and rational design of NA structure for Li–S batteries are analyzed in depth, with the aim of providing promising orientations for the commercialization of high-energy-density Li–S batteries.
Prediction of metabolite–protein interactions based on integration of machine learning and constraint-based modeling

Published: July 2023

Abstract

Motivation
Metabolite–protein interactions play an important role in regulating protein functions and metabolism. Yet, predictions of metabolite–protein interactions using genome-scale metabolic networks are lacking. Here, we fill this gap by presenting a computational framework, termed SARTRE, that employs features corresponding to shadow prices determined in the context of flux variability analysis to predict metabolite–protein interactions using supervised machine learning.

Results
By using gold standards for metabolite–protein interactomes and well-curated genome-scale metabolic models of Escherichia coli and Saccharomyces cerevisiae, we found that the implementation of SARTRE with random forest classifiers accurately predicts metabolite–protein interactions, supported by an average area under the receiver operating curve of 0.86 and 0.85, respectively. Ranking of features based on their importance for classification demonstrated the key role of shadow prices in predicting metabolite–protein interactions. The quality of predictions is further supported by the excellent agreement of the organism-specific classifiers on unseen interactions shared between the two model organisms. Further, predictions from SARTRE are highly competitive against those obtained from a recent deep-learning approach relying on a variety of protein and metabolite features. Together, these findings show that features extracted from constraint-based analyses of metabolic networks pave the way for understanding the functional roles of the interactions between proteins and small molecules.

Published: July 2023

Abstract
Burn injuries are a significant cause of death worldwide, leading to systemic inflammation, multiple organ failure and sepsis. The progression of burn injury is explicitly correlated with mitochondrial homeostasis, which is disrupted by the hyperinflammation induced by burn injury, leading to mitochondrial dysfunction and cell death. Mitophagy plays a crucial role in maintaining cellular homeostasis by selectively removing damaged mitochondria. A growing body of evidence from various disease models suggest that pharmacological interventions targeting mitophagy could be a promising therapeutic strategy. Recent studies have shown that mitophagy plays a crucial role in wound healing and burn injury. Furthermore, chemicals targeting mitophagy have also been shown to improve wound recovery, highlighting the potential for novel therapeutic strategies based on an in-depth exploration of the molecular mechanisms regulating mitophagy and its association with skin wound healing.
