Edge biasing and its impact on the edge and SOL turbulence
Authors: Shankar Vijay , Bisai N. , Raj Shrish , Sen A. 
Published: May 2022

Abstract
A theoretical study is made of the effect of edge biasing on the dynamics of the interchange turbulence in the edge and scrape-off layer regions. A linear analysis of a set of model fluid equations shows that biasing stabilizes the small k

y
modes. The model equations are next solved numerically, using the BOUT++ framework, to explore the nonlinear dynamics in the presence of positive or negative bias and compared to results in the absence of bias. Positive biasing is found to lead to a larger increment in plasma density and temperature as compared to negative biasing. It is further observed that cross-correlation between density and poloidal electric field at different radial positions decreases for positive biasing and in the case of negative biasing it is almost similar to that of no biasing. Plasma density and poloidal electric field fluctuations have been investigated which show that the density fluctuations increase (decrease) for positive (negative) biasing but the radially outward flux for these biasing cases always decreases mainly due to the decrease of cross-correlation between density and poloidal electric field fluctuations.

Abstract
The impact of externally applied magnetic perturbations (MPs) on fast-ion losses has been investigated by means of the light ion beam probe (LIBP) technique in the ASDEX Upgrade tokamak. The LIBP technique allows to experimentally infer the fast-ion orbit displacement induced by MPs via first-orbit losses using scintillator based fast-ion loss detector (FILD) measurements. The fast-ion orbit displacement against different applied MP spectra has been studied. These shots were conducted in ELM mitigated H-mode plasmas. A rigid rotation of the MP coils was applied with a frequency of 1 Hz, with an n = 2 configuration and changing the differential phase between the upper and lower set of coils (ΔΦul) on a shot-to-shot basis. Beam sources Q7 (tangential) and Q8 (radial) were used to probe different fast-ion orbits with FILD1. The measured fast-ion orbit displacement ranges from 3 to 20 mm approximately, and no qualitative difference is observed between ions from beam sources Q7 and Q8. The minimum is found for a ΔΦul ∼ 50°, which is shifted with respect to the minimum of the plasma boundary displacement, found at ΔΦul ∼ 0°. A first attempt to validate the orbit following code ASCOT—including the plasma response calculated with the MARS-F code—against these experimental measurements is performed. While the dependence of the first-orbit fast-ion displacement with ΔΦul does not match the experimental measurements, these simulations do capture other features such as the order of magnitude of the orbit displacement and the importance of the toroidal spectrum of the applied perturbation.

Abstract
In magnetic confinement fusion (MCF), the plasma always exhibits an anisotropic temperature distribution, which may impact not only the plasma dynamics but also the nuclear reaction process. Here, through theoretical derivations and self-consistent particle-in-cell simulations with the newly-developed nuclear reaction and alpha particle energy deposition calculation modules, we find that, if considering the plasma has an anisotropic temperature distribution, the fusion energy gain factor (Q) of MCF is significantly modified, where both the deuteron–triton nuclear reactivity and the alpha particle energy deposition fraction are heavily influenced. The simulation results show that, under the International Thermonuclear Experimental Reactor (ITER) condition, if the plasma temperature anisotropy ratio can reach 0.1, i.e., the plasma perpendicular temperature component is one-tenth of its parallel component corresponding to the ambient magnetic field direction, the Q-value of ITER can be increased from the originally-designed 5 to about 10, with doubled enhancement.
Extrinsic noise effects on ribosomal traffic during the translation process
Authors: Sharma Rati 
Published: May 2022

Abstract
Any cellular process at the microscopic level is governed by both extrinsic and intrinsic noise (IN) and same is true for mRNA translation as well. Even though the effect of stochasticity via the IN is well studied for mRNA translation, same cannot be said about extrinsic noise (EN). In this article, we incorporate EN in a model of mRNA translation and carry out stochastic simulations of the same. We then evaluate various statistics related to the residence time of the ribosome and the ribosomal traffic on the mRNA and subsequent protein production. We also study the effect of slow codons and ribosome dropoff. From our simulations, we show that noise in the translation initiation rate rather than the translation termination rate acts to significantly broaden the distribution of ribosome residence times on the mRNA lattice. This EN also has an effect on ribosomal current, density and protein production. Further, the presence of slow codons acts to increase the mean residence times. However, this increase also depends on the number and position of the slow codons on the lattice. We also show that the slow codons act to mask any effect from the EN themselves. Our results, therefore, have implications towards a better understanding of the role the individual components play during the translation process.

The transfer of heat through nanostructures differs significantly from the corresponding processes inside macroscopic bodies. Various research methods, both theoretical and experimental, are applied to such objects. This approach to nanostructures gives great advantages. The hyperbolic equations we have obtained describe the wave process of the thermal signal flow and the properties of heat transfer in nanostructures across a thin layer, in which the simplest task is to determine the thermal conductivity.

Published: May 2022

Abstract
The results of the polymer film investigation are considered in that paper. These films are obtained in atmospheric pressure barrier discharge from aniline with simultaneous generation of carbon particles in the films. It is demonstrated that the structure of these films corresponds to one of the amorphous polymers. Carbon particles produce agglomerates with a concentration that slightly depends on the discharge energy density. The authors show that the conductivity of aniline films with carbon particles mainly depends on water saturation.

Abstract
The effect of plasma flow from a discharge with a solution cathode on the properties of a low-current electric arc has been experimentally studied. Electric power was supplied to the arc from a GORN-type inverter source. A rectifier served as a power source for the discharge with a solution cathode. The output voltage was 1700 V. Aqueous solutions of table salt were used in the experiments. The specific electrical conductivity of the solutions was in the range of 10–15 mS/cm. The electric arc was ignited between horizontally oriented rod electrodes. The interelectrode distance varied within 2–15 mm. The discharge current with a water cathode was established within 8–15 A. The arc burned in the current range of 1–8 A. The conditions under which stable burning of the electric arc is ensured are revealed.

Abstract
Non-thermal plasma (NTP) has a non-specific bactericidal effect as a result of the synergistic activity of biologically active components contained in the plasma torch. As part of this work, we investigated the potential of using NTP for the antibacterial treatment of titanium implants. Applying samples made of the VT6 titanium alloy used to create implants and a strain of antibiotic-resistant staphylococcus MRSA, we showed that 1) plasma pretreatment of the sample surface led to the formation of a film containing titanium oxides which have a weak bactericidal effect reducing the colonization of the surface with staphylococcus; 2) direct plasma treatment of a polished titanium disk for 120 seconds reduced the contamination of S. aureus by 563 times; 3) the relief of the titanium surface itself plays an important role in the effectiveness of decontamination: the bacteria on the rough surface were less susceptible to the effects of NTP than the bacteria on the polished surface. In total, the data obtained indicate the need to continue research aimed at increasing the effectiveness of the bactericidal activity of NTP against bacteria on the surface of titanium implants.

Abstract
The paper presents some results of experimental studies of Mo/Si multilayer degradation under UV exposure from compressed plasma jets in air. Such high current plasma flows generate broadband powerful UV radiation fluxes. A single exposure caused a slight decrease of reflectivity from 0.54 to 0.47 due to the coating contamination by the debris from the plasma light emitter.

Abstract
New detector approaches in Positron Emission Tomography
imaging will play an important role in reducing costs, lowering
administered radiation doses, and improving overall
performance. PETALO employs liquid xenon as the active scintillating
medium and UV-sensitive silicon photomultipliers for scintillation
readout. The scintillation time in liquid xenon is fast enough to
register time-of-flight information for each detected coincidence,
and sufficient scintillation is produced with low enough
fluctuations to obtain good energy resolution. The present
simulation study examines a full-body-sized PETALO detector and
evaluates its potential performance in PET image reconstruction.

Abstract
As one of the three payloads of the Advanced Space-based
Solar Observatory (ASO-S), the pre-launch characterization of HXI
includes the characterization of the collimator and the
spectrometer. This article focuses on the pre-launch
characterization of HXI's spectrometer, including detection
efficiency, energy resolution, and energy to ADC channel (E-C)
relationship. The detection efficiency characterization necessitates
a sufficient number of calibrated energy points in the HXI
observation energy range, with a refined measurement around the
absorption edge of the lanthanum bromide crystal, and is calibrated
with an X-ray beam. The characterization results are consistent with
the simulations and show that the detection efficiency difference
between detector modules is controlled within ±3%. Radioactive
sources 133Ba and 137Cs are used to
calibrate the energy resolution and E-C relationship. The
characterization results show that all detector modules' energy
resolutions are better than 26% at 32 keV, meeting the design
specification. And their E-C relationships vary regularly with
voltage. All of the characterization results indicate that the
flight model of the HXI spectrometer meets the performance
requirements and is capable of performing on-orbit observation
activities.
A New Approach for Storage Capacity and Allowable Injection Time Calculation in Carbon Capture and Storage (CCS) Reservoir
Authors: Jaya Anthony Kurnia , Syihab Zuher 
Published: May 2022

Abstract
In reducing the CO2 emissions in the atmosphere, some energy industry start to implement the Carbon Capture Storage (CCS). However, there still less restriction and considerations in calculating the storage capacity and allowable injection time of CCS reservoir which might lead into leakage problem. In overcoming this problem, there is a study conducted to make a new calculation with higher accuracy. In this study, the reservoir model is using CMG software with base model of East Natuna Field. Then, this model is used to make a sensitivity analysis for 10 CCS fields with a support of CMG-CMOST and Eureqa software. The result is an equation with an R-Square of 96.6% for storage capacity and 95.4% for allowable injection time. The considered parameter in the new equation are permeability, porosity, fracture pressure, thickness, area, reservoir temperature, and reservoir pressure. To validate the new equation, a case study is made for 3 CCS fields. The result shows that the new equation shows up to 21% smaller storage capacity and 7 years reduction in allowable injection time. The result is reasonable due to additional restrictions. Therefore, it is believed that the generated equation is valid and more beneficial compared to the conventional equation.
Study of terrain correction computation using square pattern and sloped triangle methods in Karangsambung
Authors: Salam R A , Wahyudi E J , Setianingsih  
Published: May 2022

Abstract
Conventional assessments of terrain correction are carried out by laying transparent paper containing the Hammer chart on topographic maps, then estimating the elevation for each of Hammer chart’s compartment. This procedure has disadvantages, the number of compartments is too small, and there is a subjectivity from the observer in estimating the compartment’s height, especially in an area with varied topography, such as Karangsambung. These research aims are to study the effect of the topography around Karangsambung on terrain correction value and to overcome problems in conventional terrain correction estimation. Estimation of terrain correction carried out using square pattern and sloped triangle method, where the area around measurement points divided into square and triangle compartment. Based on the results, South Seraju Ranges, with an altitude of 1000 m at a distance of 20 – 30 km from Karangsambung gives an effect of 0.05 mGal on terrain correction, while the Quaternary Volcano with height of 3000 m at range of 30 – 40 km gives the effect of 0.1 mGal. The results of applying the program at the gravity data show that the use of the square pattern and sloped triangle method can correct errors from conventional estimation up to 3 mGal.

Authors: Wijanarko Edy , Grandis Hendra 
Published: May 2022

Abstract
Gravity method is often used to estimate the sedimentary basin configuration at the preliminary stage of oil and gas exploration. This paper aims at the determination of 3D basement topography based on gravity data and known depth at several points. The gravity-depth relationship is used to determine the initial model and to adjust the model iteratively from the residuals. The algorithm is relatively simple and fast, since it does not involve matrix inversion nor multiplication. The proposed method also allows density contrast estimation. Tests using synthetic data showed satisfactory results in both synthetic model recovery and low RMS misfit after a few iterations.

Published: May 2022

Abstract
The vertical gradient gravity method is one of the developments from the conventional gravity method. The advantage of this method is that it is able to detect the presence of shallow anomalies below the soil surface. In addition, this method is also able to minimize errors resulting from processing and correcting data. This research was conducted by testing the vertical gradient gravity method which is carried out with signal processing or with a vertical gradient gravity filter and the vertical gradient gravity method which is carried out by direct measurement. It was found that the vertical gradient gravity method which was carried out by direct measurements resulted in a clearer pattern in determining the presence of shallow anomaly sources.
GMODL: An Indonesian MATLAB-based ground-penetrating radar data modeling and processing software

Published: May 2022

Abstract
Ground-penetrating radar (GPR) data modeling and processing is crucial to near-surface geophysics. Its use in geohazard mitigation, construction, shallow hydrocarbon contamination, and other shallow subsurface detection is undeniable due to its high-resolution imaging. GPR software (MATGPR) that we used currently requires access to MATLAB which not everybody can use because of its licensing prices. Thus, we developed this program (GMODL) that uses finite-difference time-domain (FDTD) and split-step Fourier algorithms. To test the software, we created synthetic models. The synthetic model used for the testing is a river model for flood mitigation that consists of a layer of freshwater with ρ = 20 Ωm, k = 81 and μ
r = 1 of depth 5 m, two layers of sandstone with ρ = 850 Ωm, k = 2.5 and μ
r = 1 of total depth 4 m, and a layer of claystone with ρ = 120 Ωm, k = 11 and μ
r = 1 of depth 1 m. The GPR antenna frequency is set to 250 MHz. The testing algorithm of GMODL shows that it can create a synthetic radargram for the river model. The boundary layers are obvious to identify. Also, the freshwater thickness can be determined from the radargram.
