What do we know about translators’ job satisfaction?
Authors: Ruokonen Minna , Svahn Elin 
Published: April 2024

Abstract
This article is an exploratory overview of research on translators’ job satisfaction (JS). We analyze the data (51
articles) for indications of (1) translators’ overall JS; (2) associations of overall JS with individual, job-intrinsic,
job-extrinsic, societal, and background factors; (3) translators’ satisfaction with job-intrinsic, job-extrinsic, and
societal aspects of their work. Translators’ overall JS in the data is fairly high, and it is linked to emotional intelligence,
the nature of translating, autonomy, interpersonal relationships, status perceptions, working mode, gender, and experience. The
translators studied are mostly happy with the job-intrinsic aspects, but their views on extrinsic and societal aspects are more
divided. Gaps in research include individual factors (e.g., self-efficacy, personality traits), background factors (e.g., cultural
and socio-economic differences), and the interaction of the different types of factors.

The goal of this study is to investigate the evolution of temperatures and absolute number densities of oxygen atoms along the effluent of a low-pressure CO2 microwave discharge in order to gain insights into some of the mechanisms governing the post-discharge regime. The plasma source is operated at conditions of

These operating conditions exhibit high CO2 conversions (up to 90%) at low energy efficiencies (2%–7.4%), due to direct electron impact dissociation driving the conversion process resulting in splitting of CO2 into CO and metastable oxygen atoms. The TALIF measurements yield spatially resolved translational temperatures between

This behavior indicates the potential significance of quenching of metastable oxygen atoms within the post-discharge regime of the investigated CO2 discharges.

Investigation of sediment thickness in the rammang-rammang maros karst area using microtremor method
Authors: Arsyad M , Hasaniyah S , Susanto A 
Published: April 2024

Abstract
The aims of this study were to analyze the value of dominant frequency and amplification, estimate the thickness of the sediment, and to evaluate the seismic vulnerability of the Rammang-Rammang Maros Karst Area. This work was carried out at the Rammang-Rammang Maros Karst Area, Salenrang and Bontolempangan Village, Bontoa District, Maros Regency, South Sulawesi. Microtremor data were analyzed using the Horizontal to Vertical Spectra Ratio (HVSR) method to obtain the H/V curve representing the dominant frequency and amplification values. The dominant frequency values were obtained in the range from 1.389 to 6.251 Hz. The amplification values were in the range from 0.455 to 3.944. The sediment thickness was obtained in the range from 18.521 to 88.029 m, and the seismic vulnerability was in the range from 0.040 to 5.761. High values of sediment thickness were obtained in riverbank areas, which indicated that the weathering that occurred was caused by weathering of limestone and sedimentation by rivers. Meanwhile, low sediment thickness values were obtained in karst hill areas, indicating that the weathering occurred due to the limestone dissolution process. Based on the seismic vulnerability and amplification, the Rammang-Rammang Maros Karst Area is in a relatively safe zone.

Published: April 2024

Abstract
Bituminous grade coal is a promising and cost-effective raw material for supercapacitor electrode application. Carbonization plays a crucial role in transforming the organic components present in raw coal into a carbon-rich structure with an enhanced capacity for charge storage. In this research, we study carbonized bituminous coal (CBC) as a preliminary evaluation of its electrochemical properties. The carbonized bituminous coal was synthesized through a simple heat treatment at temperatures of 700 and 900°C under a continuous flow of argon gas for 2 hours. The structural behavior of carbonized bituminous coal was analyzed using several characterizations, including x-ray diffraction (XRD), Fourier transform infrared (FTIR), and Raman spectroscopy. Furthermore, the electrochemical properties were evaluated using cyclic voltammetry (CV) and galvanostatic charge-discharge in a 3 M electrolyte solution of potassium hydroxide (KOH) with a three-electrodes configuration. The specific capacitances of 49.75 F g−1 and 20.00 F g−1 at a current density of 0.5 A g−1 were achieved for the sample produced at the carbonization temperature of 700 and 900°C, respectively. These values are considerably higher than the specific capacitance of raw bituminous coal (0.687 F g−1) at 0.5 A g−1. This result may offer valuable insight for the further development of coal-based supercapacitor electrodes.

Abstract
We developed the All-Sky Camera using a CMOS sensor, which is integrated with various other supporting devices to optimize image and video recordings. In general, CMOS cameras are not equipped with a cooling system, which can cause increased noise. Therefore, our design is equipped with an external cooling system to keep the temperature stable at night or during the day. In addition, our designs are also equipped with various other sensors, such as rain sensors, cloud sensors, light sensors, and sensors for environmental conditions such as pressure, temperature, and humidity. The development of the All-Sky Camera will also be used as a tool to monitor the sky throughout Indonesia with the Indonesian Sky Patrol Network (https://allskycam.or.id/). As a result, we managed to record several astronomical phenomena, such as meteors and space debris. For future scientific needs, the all-sky camera that we have developed is also used to monitor changes in light pollution and identify sources of light pollution, as well as the quality of the atmosphere at the ITERA Lampung Astronomical Observatory Environment (OAIL).

Authors: Hamzah Y , Febiola A , Umar L , Salomo  
Published: April 2024

Abstract
This research aims to synthesize zinc oxide nanoparticles using Terminalia catappa leaf extract. The synthesis method used Terminalia catappa leaves as a reductor. Synthesized ZnO nanoparticles were characterized using UV-vis, XRD, SEM, and TEM. UV-vis spectroscopy of samples showed peak absorption in the 300-380 nm range. The results of XRD characterization show that the ZnO nanoparticles crystal structure is hexagonal wurtzite, where the highest peak of reflection occurs at the reflection angle 2θ=36.24 of the crystal plan (101). SEM characterization results refer to flower-shaped morphology with a size distribution between 392-423 nm. These findings reveal morphology insight into the photocatalytic of ZnO nano-flowers for the environment.

Published: April 2024

Abstract
The application of metal nanoparticles in medicine and optoelectronic devices recently has shown remarkable results. In the application of biosensor, metal nanoparticles are functionalized by the used of organic materials such as thiol-derivatives and citrate because of their high affinity to metal such as gold and silver also those organic material is dispersed in water that can be applied directly to bio-materials. Herein, we present the optimization study of capping molecules Trisodium citrate and 3-mercaptopropionic acid (3-MPA) on silver nanoparticles (AgNP) by used of modified chemical reduction and exchange ligand methods to form stable AgNP. The optimization of AgNP was done by varying the ratio among the concentration of the precursor (AgNO3), reducing agent and capping materials. Our colloidal AgNP products show bright yellow to yellow-brownish colour with the plasmonic peak for citrate capped AgNP (Ag-Citrate) at 410-424 nm, 3-MPA capped AgNP (Ag-MPA) by direct method at 428-440 nm, and 3-MPA capped AgNP (Ag-MPA) by ligand exchange method at 436-462 nm. The chemical characteristics of our Ag-citrate and Ag-MPA show the differences coordination of COO- between free citrate or 3-MPA and after citrate or 3-MPA capped on Ag. In our experiment, the TEM images for both samples of AgNPs show the spherical shape with the range of diameter size 5-38 nm which depends on the given ratio of material concentration in the synthesis process. Our AgNP solution results with the open capping of citrate or 3-MPA then can be applied as probe sensor for plasmonic sensor application.

Published: April 2024

Abstract
Many properties of the spin–½ kagome Heisenberg antiferromagnet remains controversial and receiving continuous attention from theorists and experimentalists due to their fascinating magnetic properties and high heterogeneity coax by the geometrical frustration. In this research we seek and compare the results obtained in our recent article [1] with that of Napel[2] where we elucidate some of the identified magnetic behaviour using the spin–½ Heisenbeg model with the application of Exact Diagonalization and classical Monte-Carlo simulation on three site dimer and 3D simple cubic lattice simulation. The results obtained shows excellent agreement in both papers reviewed with [1] establishing firmly the FM to AFM transition, having a clear transition point referred to mixed phased [2].
Utilizing Convolutional Autoencoder for Anomaly Detections in LIGO Spectrogram Data
Authors: Imran Adrian Ramadhana 
Published: April 2024

Abstract
Massive amounts of data generated from the continuous running of LIGO gravitational-wave detectors comes with a need to search for signals within the data. Gravitational-wave data captured by the detector consist of astronomical events or glitches that last seconds. We present an unsupervised learning using convolutional autoencoder trained on the no-glitch Gravity Spy dataset to do anomaly search on spectrogram data. Reconstruction error is used as the basis and multiple windows are used to improve the model. Results on test data show that the model is capable of detecting signals with significant anomalies such as the Chirp or Koi Fish glitch. Meanwhile, detecting subtle anomalies such as the 1400 Hz Ripples is difficult because its reconstruction error is near the range of noise signals. Validating the result on confirmed gravitational-wave signals shows that the model is capable of gravitational-wave detection.
A comparison of the neutron detection efficiency and response characteristics of two pixelated PSD-capable organic scintillator detectors with different photo-detection readout methods
Authors: Balajthy J. , Marleau P. , Sweany M. 
Published: April 2024

Abstract
We characterize the performance of two pixelated neutron
detectors: a PMT-based array that utilizes Anger logic for pixel
identification and a SiPM-based array that employs individual pixel
readout. The SiPM-based array offers improved performance over the
previously developed PMT-based detector both in terms of uniformity
and neutron detection efficiency. Each detector array uses
PSD-capable plastic scintillator as a detection medium. We describe
the calibration and neutron efficiency measurement of both detectors
using a 137Cs source for energy calibration and a 252Cf
source for calibration of the neutron response. We find that the
intrinsic neutron detection efficiency of the SiPM-based array is
(30.2 ± 0.9)%, which is almost twice that of the PMT-based
array, which we measure to be (16.9 ± 0.1)%.
Non-inertial interpretation of the Dirac oscillator
Authors: Marrocco Michele 
Published: April 2024

Abstract
Non-inertial physics is seldom considered in quantum mechanics and this contrasts with the ubiquity of non-inertial reference frames. Here, we show an application to the Dirac oscillator which provides a fundamental model of relativistic quantum mechanics. The model emerges from a term linearly dependent on spatial coordinates added to the momentum of the free-particle Dirac Hamiltonian. The definition generates peculiar features (mutating vacuum energy, non-Hermitian momentum, accidental degeneracies of the spectrum, etc). We interpret these anomalies in terms of inertial effects. The demonstration is based on the decoupling of the Dirac equation from the stereographic projection that maps the 3D geometry of the dynamical problem to the complex plane. The decoupling shows that the fundamental mechanical model underpinning the Dirac oscillator reduces to the representation of the oscillator in the rotating reference frame attached to the orbital angular momentum. The resulting Coriolis-like contribution to the Hamiltonian accounts for the peculiarities of the model (mutating vacuum energy, form of the non-minimal correction to the momentum, classical intrinsic spin and gain of its quantum value, accidental degeneracies of the energy spectrum, supersymmetric potential). The suggested interpretation has an interdisciplinary character where stereographic geometry, classical physics of the Coriolis effect and quantum physics of Dirac particles contribute to the definition of one of the few exactly soluble models of relativistic quantum mechanics.

Abstract
A liquid Li divertor is a promising alternative for future fusion devices. In this work a new divertor model is proposed, which is processed by 3D-printing technology to accurately control the size of the internal capillary structure. At a steady-state heat load of 10 MW m−2, the thermal stress of the tungsten target is within the bearing range of tungsten by finite-element simulation. In order to evaluate the wicking ability of the capillary structure, the wicking process at 600 °C was simulated by FLUENT. The result was identical to that of the corresponding experiments. Within 1 s, liquid lithium was wicked to the target surface by the capillary structure of the target and quickly spread on the target surface. During the wicking process, the average wicking mass rate of lithium should reach 0.062 g s−1, which could even supplement the evaporation requirement of liquid lithium under an environment > 950 °C. Irradiation experiments under different plasma discharge currents were carried out in a linear plasma device (SCU-PSI), and the evolution of the vapor cloud during plasma irradiation was analyzed. It was found that the target temperature tends to plateau despite the gradually increased input current, indicating that the vapor shielding effect is gradually enhanced. The irradiation experiment also confirmed that the 3D-printed tungsten structure has better heat consumption performance than a tungsten mesh structure or multichannel structure. These results reveal the application potential and feasibility of a 3D-printed porous capillary structure in plasma-facing components and provide a reference for further liquid−solid combined target designs.

Abstract
In the design realm of fusion power supplies, structural components play a pivotal role in ensuring the safety of fusion devices. To verify the reliability of the converter structure design at the Comprehensive Research Facility for Fusion Technology (CRAFT), meticulous analysis of the converter's dynamic impact is carefully performed based on the worst fault current (400 kA), firstly. Subsequently, the thermal stress analysis based on the maximum allowable steady-state temperature is finished, and the equivalent thermal stress, thermal deformation, maximum shear stress of a single bridge arm and the whole converter are studied. Furthermore, a simple research method involving the current-sharing characteristics of a bridge arm with multi-thyristor parallel connection is proposed using a combination of Simplorer with Q3D in ANSYS. The results show that the current-sharing characteristics are excellent. Finally, the structural design has been meticulously tailored to meet the established requirements.

Published: April 2024

ABSTRACT
The chemical investigation of the roots of Lindera glauca guided the isolation and identification of 3 new sesquiterpenoids, namely glaucatotones J−L (1−3), and one known congener, (1β,5β)-1-hydroxyguaia-4(15),11(13)-dieno-12,5-lactone (4). The structures of new compounds were established based on comprehensive spectrographic methods, mainly including 1D & 2D NMR and HRESIMS analyses, and the absolute configurations were further confirmed by the comparison of experimental and calculated electronic circular dichroism. The cytotoxicity activities of isolates were evaluated, and the results showed that they have moderate cytotoxic activities.
Astringency and its sub-qualities: a review of astringency mechanisms and methods for measuring saliva lubrication
Authors: Wang Shaoyang , Smyth Heather E , Olarte Mantilla Sandra M , Stokes Jason R , Smith Paul A 
Published: April 2024

Abstract
Astringency is an important mouthfeel attribute that influences the sensory experiences of many food and beverage products. While salivary lubricity loss and increased oral friction were previously believed to be the only astringency mechanisms, recent research has demonstrated that nontactile oral receptors can trigger astringency by responding to astringents without mechanical stimulation. Various human factors have also been identified that affect individual responses to astringents. This article presents a critical review of the key research milestones contributing to the current understanding of astringency mechanisms and the instrumental approaches used to quantify perceived astringency intensity. Although various chemical assays or physical measures mimic in-mouth processes involved in astringent mouthfeel, this review highlights how one chemical or physical approach can only provide a single measure of astringency determined by a specific mechanism. Subsequently, using a single measurement to predict astringency perception is overly idealistic. Astringency has not been quantified beyond the loss of saliva lubrication; therefore, nontactile receptor-based responses must also be explored. An important question remains about whether astringency is a single perception or involves distinct sub-qualities such as pucker, drying, and roughness. Although these sub-quality lexicons have been frequently cited, most studies currently view astringency as a single perception rather than dividing it into sub-qualities and investigating the potentially independent mechanisms of each. Addressing these knowledge gaps should be an important priority for future research.
Identification and characterization of a novel type of ketohexokinase from the haloarchaeon Haloferax volcanii
Authors: Ortjohann Marius , Schönheit Peter 
Published: April 2024

Abstract
Ketohexokinase (KHK) catalyzes the ATP-dependent phosphorylation of fructose, forming fructose-1-phosphate and ADP. The enzyme is well studied in Eukarya, in particular in humans and other vertebrates, but homologs have not been identified in Bacteria and Archaea. Here we report the identification of a novel type of KHK from the haloarchaeon Haloferax volcanii (HvKHK). The encoding gene khk was identified as HVO_1812. The gene was expressed as a 90-kDa homodimeric protein, catalyzing the phosphorylation of fructose with a Vmax value of 59 U/mg and apparent KM values for ATP and fructose of 0.47 and 1.29 mM, respectively. Homologs of HvKHK were only identified in a few haloarchaea and halophilic Bacteria. The protein showed low sequence identity to characterized KHKs from Eukarya and phylogenetic analyses indicate that haloarchaeal KHKs are largely separated from eukaryal KHKs. This is the first report of the identification of KHKs in prokaryotes that form a novel cluster of sugar kinases within the ribokinase/pfkB superfamily.
Spherical random projection
Authors: Kang Seungwoo , Oh Hee-Seok 
Published: April 2024

Abstract
We propose a new method for dimension reduction of high-dimensional spherical data based on the nonlinear projection of sphere-valued data to a randomly chosen subsphere. The proposed method, spherical random projection, leads to a probabilistic lower-dimensional mapping of spherical data into a subsphere of the original. In this paper, we investigate some properties of spherical random projection, including expectation preservation and distance concentration, from which we derive an analogue of the Johnson–Lindenstrauss Lemma for spherical random projection. Clustering model selection is discussed as an application of spherical random projection, and numerical experiments are conducted using real and simulated data.
