AbstractBased on the parsley seed main component, apiol, efficient approach to polymethoxyquinone C3- and C4-acids was developed. The key step of this approach is Baeyer–Villiger rearrangement of carbonyl-substituted polyalkoxybenzenes derived from parsley seed extracts. These acids are the MeO-analogues of natural antioxidants – metabolites of ubiquinone and idebenone. Due to antioxidant properties, they are the potential therapeutic candidates for the treatment of mitochondrial dysfunction.

Abstract
Introduction Osteoarthritis (OA) is common among older adults, and studies have suggested that it is commonly associated with sleep problems and depression. However, the results are inconsistent concerning overall sleep quality, daytime sleepiness, and depression in studies that consider OA knee pain specifically.
Objectives To examine the relationship between sleep quality, daytime sleepiness and depression, and OA knee pain in older adults.
Methods This was a cross-sectional study. Adults aged 60 and above with OA knee pain according to the National Institute for Health and Care Excellence (NICE) guidelines, and who had preserved cognitive function were recruited. Sleep quality, daytime sleepiness, and depression symptoms were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), and the Center for Epidemiologic Studies Depression Scale (CESD), respectively. The generalized linear model (GzLM) approach was used in the statistical analysis. A logistic regression model was performed to evaluate whether ESS, PSQI, and CESD symptoms were associated with knee pain.
Results The sample comprised 451 older adults. Sleep quality (OR = 1.22, 95% confidence interval [CI]: 1.07 to 1.40) and depressive symptoms (OR = 1.09, 95%CI: 1.01 to 1.17) were associated with knee pain, but there was no association with excessive daytime sleepiness (OR= 1.09, 95%CI: 0.90 to 1.20).
Conclusions Sleep quality and depression symptoms are associated with knee pain.

Published: June 2024

AbstractHemophilia is a rare X-linked congenital bleeding disorder due to a deficiency of factor VIII (hemophilia A [HA]) or factor IX (hemophilia B [HB]). Replacement and nonreplacement treatments are available but have limitations. Gene therapy (GT) provides an effective, long-term, single-dose treatment option, now approaching clinical practice. This study aimed to understand patient perspectives on GT for HA and HB in Italy using a qualitative questionnaire distributed through Italian patient associations, addressing patient views on daily life, treatments, unmet needs, quality of life (QoL), and GT for hemophilia. In total, 141 participants had HA, and 14 had HB (severe 78.6%). Daily life was most affected by pain and/or joint function limitations (57.5% of participants), high infusion frequency (42.5%), management of breakthrough bleeding episodes (40.3%), and anxiety/fear of severe or sudden bleeding (38.8%). Despite current treatments, about half of the participants experienced three or more annual bleeding episodes. Most participants knew of GT (87.2%) and expected improvements in QoL (60.5%), reduced frequency of current treatments (53.5%), and a permanent cure (49.1%); 46.4% were unaware of its once-off dosage and 46.4% were not concerned about the costs they anticipated to be associated with GT. Although several fears were reported, 25.0% of participants were willing to undergo GT with the support of a multidisciplinary team. This survey provided valuable insight into patient perspectives on hemophilia and GT in Italy. Overall, relevant proportions of patients still experience limitations affecting their daily life. Most were positive about GT and anticipated improvements in their clinical outcomes and QoL.
Total Anomalous Pulmonary Venous Connection with Rare Direct Right Atrial Drainage and Unprecedented Array of Coexistent Multisystem Variations

Published: June 2024

AbstractTotal anomalous pulmonary venous connection (TAPVC) is anomalous drainage of all pulmonary veins into systemic circulation. The intracardiac type typically entails the drainage of all the pulmonary veins into the right atrium, via the coronary sinus. The connection of the pulmonary veins directly into the right atrium is exceptionally rare and has been primarily reported with right atrial isomerism. Herein, we presented a remarkable case of TAPVC in a 10-year-old male child, distinguished by an unconventional drainage of all the pulmonary veins directly into the right atrium, with normal coronary sinus and absent right atrial isomerism. Intriguingly, computed tomography imaging revealed a combination of incredibly rare coexistent pulmonary, vascular, and skeletal anomalies. These anomalies included absence of pulmonary fissures in the right lung, presence of left circumflex aortic arch with bovine branching pattern, bilateral cervical ribs, and C7 vertebral fusion anomalies. To our knowledge, this unique combination of coexistent anomalies has not been previously reported in scientific literature in the background of rare drainage pattern of TAPVC.
State Capacity of Secret Surveillance
Authors: Duncan Thomas K. , Goodman Nathan P. 
Published: June 2024

Abstract
The state capacity-civil society tradeoff model tends to treat the “state” and “civil society” as separate entities who move to constrain one another. However, this modeling technique leaves out the nuances of individual action within a collective setting by treating each as a relative black box. This article explores this balance in the context of the surveillance state that has arisen in the 20th and 21st century. As state capacity in surveillance increases it better allows the state to respond to threats to citizens from citizens. However, the increased capacity also lessens the ability of societal pressure to check authoritarian advances even in a nation with a thriving civil society presence.
A high temperature in situ optical probe for colloidal nanocrystal synthesis
Authors: Keating Logan P. , Huang Conan , Shim Moonsub 
Published: June 2024

We report on the fabrication and utilization of a robust high-temperature (&gt;300 °C), adjustable-path-length, vacuum-tolerant, configurable, in situ optical probe, which interfaces with widely used chemical glassware via a 14/20 ground glass joint. This probe allows for high-speed reaction monitoring of colloidal semiconductor nanocrystal solutions at temperatures that were previously inaccessible. We demonstrate this capability by monitoring the hot-injection synthesis of CdSe quantum dots via UV–Vis absorption spectroscopy at 380 °C with a time resolution of ∼10 ms, with the primary limitation being the acquisition and data saving rate of the commercial spectrometer used. We further demonstrate that this probe can also be used for in situ photoluminescence measurements. This system is generally applicable to harsh solution environments where optical monitoring of reaction progress is desirable and/or necessary.
Measuring the linguistic similarity of discourse from open-world role-playing games to the real world through an additive multidimensional analysis
Authors: Dixon Daniel H. 
Published: June 2024

Abstract
Digital games can provide rich sources of second language (L2) input; however, the extent to which gaming discourse is similar to real-world discourse has been a topic of debate in the computer-assisted language learning community. To quantitatively measure the extent to which gaming discourse shares linguistic similarity with real-world discourse, this study reports the findings of an additive multidimensional (MD) analysis comparing registers in open-world role-playing games to real-world registers using Biber’s (1988) Dimension 1: ‘Involved versus Informational Production.’ Results indicate that gaming discourse provides extensive language exposure that shares much linguistic similarity across a wide range of real-world contexts. Importantly, however, these similarities only become salient when the situational characteristics of gaming discourse are considered and parsed appropriately into register categories.

Abstract
The N = 34 isotope 55Sc has been investigated using in-beam γ-ray spectroscopy at the RIKEN Radioactive Isotope Beam Factory. Spectra from the direct (p, pn) reaction as well as indirect reaction channels have been investigated. γ rays with energies 496(10), 570(12), 682(14), 1510(30), 1780(36), 2345(57) and 2470(50) keV have been observed. A level scheme was constructed based on γ
γ coincidence analysis and relative intensities. The results have been compared to the level scheme already reported in literature, as well as to large-scale shell model calculations in the sd − pf model space. A new level at 1510keV, decaying directly to the ground state, has been proposed and spin-parity J

π
= 7/2− was tentatively assigned. The effect of including the ν

9/2 orbital is discussed. It can be concluded that the main low-energy properties of 55Sc seem to be included in the original sd − pf model space.

Abstract
In this study, we analyzed masses and decays of triply-heavy pentaquarks

in the unified MIT bag model. We construct the color-spin wave functions of the triply-heavy pentaquarks and use the numerical variational method to compute all the ground-state masses of these systems. By excluding the scattering states in configuration spsce, we computed the decay width ratios of each decay channel relative to the maximum width for the compact pentaquark states, obtaining the main decay modes of the triply-heavy pentaquark systems.

Abstract
The Solo-Jogja NYIA Kulon Progo toll road construction project section 1 package 1.1, which connects Kartasura to Klaten Regency. Based on the regional geological conditions, the Klaten interchange at STA 21+800-22+300 is situated in the Opak Merapi-Merbabu fault area predominantly composed of sandy lithology. Consequently, there is a potential for liquefaction when an earthquake occurs. This research analysis of liquefaction potential using a field test data approach, namely the SPT (Standard Penetration Test) was conducted to assess the seismic and subsurface conditions at Klaten Interchange STA 21+800 - 22+300. The seismic conditions at the Klaten interchange, located 6-7 km from the Opak fault, result in a Peak Ground Acceleration (PGA) value of 0.78 g, corresponding to class 5 on the BMKG MMI scale, potentially causing serious damage to buildings. The VS30 value in the research area ranges from 278.9 - 654.3 m/s, indicating a medium soil type. Subsurface conditions at STA 21+800-21+300 are divided into three zones based on the distance of each borehole. The SPT result shows that zone 1 is dominated by Silty Sand with Loose to Medium Dense consistency, zone 2 is dominated by Silty Sand to Sand with Medium Dense to Very Dense consistency, zone 3 is dominated by Silty Sand with a Medium Dense to Very Dense consistency. The results of the liquefaction potential calculation study indicate that several borehole points have the potential for liquefaction because the safety factor (FS) value is less than 1. Zone 1 has three points that have the potential for liquefaction: DBs-01, DBs-05, and DBs-07. Zone 2 includes two points with potential liquefaction: DBs-08 and DBs-09. Zone 3 has one point with potential for liquefaction: DBs-10.

Published: June 2024

Abstract
Institut Teknologi Sepuluh Nopember (ITS) Surabaya is geologically vulnerable to earthquake hazards. Therefore, preparedness is necessary to address emergencies and risks caused by earthquake at ITS Surabaya. In this study, dispersion curve were obtained through the analysis of microtremor data using the Spatial Autocorrelation (SPAC) method. Microtremor data acquisition was performed at the PLN ITS Futsal Field using L- and triangle-arrays. We successfully got dispersion curves from both arrays. The shear wave velocity (Vs) profile and the best model of Vs profile for each array were obtained by inverting the dispersion curves. By using a two-layer model, the first layer produces identical velocities with a depth of 5.44 meters for an L-array and 5.02 meters for a triangle array. In the second layer, the resulting velocities for each array have quite a difference. The best model of Vs profile for both arrays were used to analyse 1D soil response with a linear approach in the frequency domain. Parameters including Peak Ground Acceleration (PGA), 5% damped Pseudo Spectral Acceleration (PSA), and Fourier Amplitude Ratio (FAR) were obtained from the linear approach analysis that could describe the ground’s response to seismic waves. Vs influences the soil response, the higher the difference in Vs values of a layer with the layer below it (half-space), the higher the increase in PGA, PSA, and FAR.

Abstract
Abaca fiber is one of the superior natural fibers in Indonesia. This fiber is also exported abroad as raw material for banknotes. Abaca fiber has superior mechanical properties including tensile strength and Young’s modulus test values. In this research, a more detailed characterization of abaca fiber has been carried out based on XRD, Gravimetry, SEM and BET analysis (Brunauer-Emmett-Teller). XRD characterization showed a relationship curve between intensity and 2θ resembling a cellulose curve. While gravimetric testing revealed three main components of abaca fibers in succession; cellulose 72.25%, hemicellulose 8.56% and lignin 8.69%. This high cellulose component caused abaca fiber to have high mechanical capabilities. BET analysis presented that abaca fiber has a Surface area 28.63 m2g−1, pore volume 0.09 ccg−1, and average pore size 4.94 nm. From the results of the analysis obtained proved that abaca fiber can be used as an alternative reinforcer in composite materials that can be applied as building materials (concrete) and acoustic materials (absorbers). In addition, abaca fiber is a natural fiber that is easily cultivated in Indonesia which is environmentally friendly and able to increase local wisdom if used scientifically.

Abstract
Increasing demand of energy storage devices stimulates growing research in supercapacitors technologies. Waste-based supercapacitor electrodes has become one of areas to be explored as they offer an environmentally friendly approach. Here we synthesis porous carbon from wastes of medical masks which have been generated a lot since the pandemic. Medical masks are composed of polypropylene which have high porosity; hence they have a potential to be used as a porous carbon source for supercapacitor applications. The synthesis routes include a solvothermal process inside a Teflon autoclave in a microwave and a washing process using dilute acid solution and distilled water. The routes successfully transform polypropylene to porous carbon, confirmed by XRD, FTIR, SEM-EDX and Raman spectrum analyses. The present of C-S bond are indicated from FTIR spectrum, implying a successful doping of sulphur into porous carbon. The electrochemical analysis of the prepared electrode using cyclic voltammetry shows an EDLC-like feature with high specific capacitance of ∼375 Fg−1 at the scan rate of 5 mV/s.

Published: June 2024

Abstract
Graphene has become a material that is often discussed recently because of its unique properties. One of the obstacles in using graphene as a nanoelectronic device is its zero band gap energy. One effort that can be made to open this energy gap is by substituting N atoms. In this research, spin-polarization density functional theory is studied. We simulated 4 x 4 single-layer graphene supercells with varying numbers of N atom substitutions (N = 0, 1, 2 atoms). The GGA – PBE function is used in this modeling to complement the exchange – correlation potential. The result obtained is an open energy band gap when the Nitrogen atom is substituted. Nitrogen substituted in the form of graphite – N also causes the emergence of a magnetic moment in graphene, with a Fermi energy value for pristine graphene of -0.4607 eV, for G1N of -1.6140 eV, and for G2N of -1.3346 eV. These results pave the way for research and development of graphene in its application as electronic nanodevices.

Published: June 2024

Abstract
Graphene is a two-dimensional material that has special characteristics. The electronic properties of graphene show zero band gap conditions. The magnetic properties of graphene can be created by modifying the electronic properties through atomic substitution. In this research, we study the magnetic and electronic properties of single-layer graphene substituted with boron (B) atoms, because it has almost the same atomic radius as carbon (C) atoms, resulting in only small lattice deformation. The spin-polarized density functional theory (DFT) method implemented in the Quantum Espresso package was selected to perform the calculations. The simulated models are a 4×4×1 supercell of pristine graphene structure consisting of 32 C atoms and boron-substituted graphene with a variety number of atoms (B = 1 and 2 atoms). The results of band gap energy obtained after the structure was optimized are 0.19 and 0.21 eV (spin-down and spin-up) for G-B and 0.36 and 0.37 eV (spin-down and spin-up) for G-2B. Boron substitution in graphene opens the bandgap and shifts the Fermi energy level. It also influences the magnetic moment of the graphene layer, estimated at 0.22 and 0.06 μB/cell for G-B and G-2B, respectively. This research shows that modifying graphene by substituting boron makes the graphene material semiconductive and weakly magnetic.

Published: June 2024

Abstract
To preserve the environment and raise the standard of production and life, the efficient utilization of solar energy is particularly important. Without coating treatment, interface reflection will cause the optical system’s transmitted light intensity to decrease, making it less effective to operate. This paper introduces the general situation for antireflective coatings consisting of SiO2/MgF2 films, fabricated on the various substrate BK7 glass and corning glass, by using a combination of spin coating and spray pyrolysis methods. This paper explains the optical characteristics impacts caused by the usage of different substrate. Comparing SiO2/MgF2 films coated on BK 7 glass to those coated on Corning glass, we found that the former has a higher transmittance value in the 350-1000 nm wavelength range, making it more effective for antireflective double layer coating.

Published: June 2024

Abstract
A study on thermal stability of light transmission on tapered plastic optical fibre (TPOF) due to PMMA/zircon composites coating has been performed. The zircon filler was obtained from purified local zircon sand. The PMMA/zircon composites were produced utilizing acetone at a temperature of 50°C. The TPOF was subjected to a dip coating procedure to apply composite coatings at varying zircon of 0, 0.5, and 1 wt.%. The characterization of light transmission on coated the TPOF, investigated at an environmental temperature range of 30 to 60°C, was conducted using an optical power meter (OPM) and a spectrometer. Based on the OPM measurements, it is known that the output power of the composite coated TPOF exhibits a high degree of linearity, even when subjected to varying environmental temperatures. The coated composite material also exhibits the capability to withstand wavelength peak shift. Therefore, it can be inferred that the composites could resist fluctuations in external temperatures. To fulfil additional objectives, the composite material can be employed as a protective layer for TPOF applications, particularly while operated at temperatures exceeding the ambient conditions.
