Simulation and Optimization of Hemispherical Resonator’s Equivalent Bottom Angle for Frequency-Splitting Suppression
Authors: Gao Zhiyong , Wang Shang , Wang Zhi , Ding Xukai 
Published: August 2023

As an inertial sensor with excellent performance, the hemispherical resonator gyro is widely used in aerospace, weapon navigation and other fields due to its advantages of high precision, high reliability, and long life. Due to the uneven distributions of material properties and mass of the resonator in the circumferential direction, the frequencies of the two 4-antinodes vibration modes (operational mode) of resonator in different directions are different, which is called frequency splitting. Frequency splitting is the main error source affecting the accuracy of the hemispherical resonator gyro and must be suppressed. The frequency splitting is related to the structure of the resonator. For the planar-electrode-type hemispherical resonator gyro, in order to suppress the frequency splitting from the structure, improve the accuracy of the hemispherical resonator gyro, and determine and optimize the equivalent bottom angle parameters of the hemispherical resonator, this paper starts from the thin shell theory, and the 4-antinodes vibration mode and waveform precession model of the hemispherical resonator are researched. The effect of the equivalent bottom angle on the 4-antinodes vibration mode frequency value under different boundary conditions is theoretically analyzed and simulated. The simulation results show that the equivalent bottom angle affects the 4-antinodes vibration mode of the hemispherical resonator through radial constraints. The hemispherical resonator with mid-surface radius R=15 mm and shell thickness h=1 mm is the optimization object, and the stem diameter D and fillet radius R1 are experimental factors, with the 4-antinodes vibration mode frequency value and mass sensitivity factor as the response indexes. The central composite design is carried out to optimize the equivalent bottom angle parameters. The optimized structural parameters are: stem diameter D=7 mm, fillet radii R1=1 mm, R2=0.8 mm. The simulation results show that the 4-antinodes vibration mode frequency value is 5441.761 Hz, and the mass sensitivity factor is 3.91 Hz/mg, which meets the working and excitation requirements wonderfully. This research will provide guidance and reference for improving the accuracy of the hemispherical resonator gyro.

Authors: Wong Sylvester Leong Kiat , Tan Vi Chee , Lam Chensen , Tan Li Mun 
Published: August 2023

Background: Idiopathic intracranial hypertension (IIH) is characterised by raised intracranial pressure and normal cerebrospinal fluid composition with no detectable intracranial aetiology. Fulminant IIH is rare and is defined by the acute onset of symptoms and signs (less than 4 weeks between onset of symptoms and severe vision loss) with progressive vision loss over days.
Case presentation: A 22-year-old woman with body mass index of 27.6 was diagnosed with fulminant IIH. Her presenting vision was hand movement and it progressed rapidly to no light perception by day 4. She was managed with oral acetazolamide and intermittent lumbar punctures. Nevertheless, she did not regain her vision.
Conclusion: Fulminant IIH is a vision-threatening condition that must be recognised and treated early to prevent irreversible vision loss.
Cessation of ocular hypertensive attacks following iStent trabecular micro-bypass stent implantation in a patient with Posner-Schlossman syndrome: a case report
Authors: Khoo Phong Yue , Tang Seng Fai , Cheng Teck Chee , Md Din Norshamsiah 
Published: August 2023

Background: Posner-Schlossman syndrome (PSS) is an ocular condition with self-limiting recurrent episodes of markedly elevated intraocular pressure (IOP) and non-granulomatous anterior chamber inflammation. Surgical treatment is indicated if medical therapy fails to control IOP.
Case presentation: A 58-year-old male presented with intermittent attacks of blurred vision and pain in the right eye for 6 months. Examination revealed keratic precipitates with IOP of 56 mmHg in the right eye. Gonioscopy revealed open angles in both eyes. Erythrocyte sedimentation rate was within normal limits, while aqueous tapfor viral PCR, rapid plasma reagent test, and Mantoux test were negative. IOP was in the high-teens (inappropriate) on 2 topical antiglaucoma medications and the patient developed ocular surface problems. iStent was implanted. IOP remained stable within the mid-teens with no further episodes of raised IOP in the following 6 months.
Conclusion: This case showed cessation of ocular hypertensive attacks in PSS after iStent implantation.
Strain distributions in carbon-doped silicon nanowires along [110] and [100] investigated by X-ray diffraction

Published: August 2023

Abstract
Carbon-doped Si films formed on Si substrates have a large tensile strain, and the strain is relaxed by microfabrication into nanowires. We investigated the effects of crystalline orientation, width and carbon concentration on lattice relaxation using reciprocal space mapping (RSM) with X-ray diffraction. RSM profiles of 400–480 periodically aligned C-doped Si nanowires on Si substrates indicate that lattice relaxation of Si0.9917C0.0083 nanowires along the [100] direction was larger than that of [110] nanowires. The effect of crystalline orientation of nanowires is considered to increase as lattice mismatch to the substrate increases, since no difference was observed in residual strains between [100] and [110] Si0.9940C0.0060 nanowires with a smaller lattice mismatch to the Si substrate. It has also been revealed that the strains of C-doped Si nanowires became more relaxed as the nanowire width decreased.

Published: August 2023

Abstract
In this work, we prepared Ca2BO3Cl with various amounts (0.1%–1.0%) of Tm2O3 by conventional solid-state reaction and investigated the dosimeter properties. Scintillation peaks at 370, 455, 470, and 650 nm that were derived from the 4f→4f transition of Tm3+ appeared in the X-ray induced scintillation spectra, and the highest scintillation intensity was detected from the 0.5% Tm2O3-doped Ca2BO3Cl. Furthermore, the Tm2O3-doped Ca2BO3Cl exhibited a thermally-stimulated luminescence (TSL) with a main glow peak at 300 °C, and the fabricated Tm2O3-doped Ca2BO3Cl exhibited a linear response in the 0.1–1000 mGy range. In addition, the TSL spectra confirmed that a final luminescence process for the TSL was the 4f→4f transition of Tm3+. In addition to TSL, optically-stimulated luminescence that was attributable to the 4f→4f transition of Tm3+ was recorded under 520 nm light, and the lowest detectable limit was about 1 mGy.

Published: August 2023

Abstract
Commercial phosphor glasses, namely, Lumilas-G9 and -R7 were investigated on their optical and scintillation characteristics. In transmittance, close to 90% transmission was achieved in both glasses at visible wavelength, and some specific absorption lines due to 4f-4f transitions of Tb3+ and Eu3+ were detected in Lumilass-G9 and -R7, respectively. In photoluminescence and scintillation, several sharp emission lines were observed in both glasses, and the emission origins of them were attributed to 4f-4f transitions of Tb3+ and Eu3+. Under pulse X-ray irradiation, the scintillation decay time of both Lumilas-G9 and -R7 resulted in 1.3 ms. To determine the scintillation light yield, α-rays from 241Am were irradiated to these samples, and the light yields of Lumilas-G9 and -R7 estimated by pulse area measurements turned out to be 700 and 1800 ph MeV−1, respectively.

Authors: Ichiba Kensei , Takebuchi Yuma , Kato Takumi , Nakauchi Daisuke , Kawaguchi Noriaki , Yanagida Takayuki 
Published: August 2023

Abstract
Y2SiO5 (YSO) single crystals with various Ce concentrations were fabricated and their photoluminescence (PL) and optically stimulated luminescence (OSL) properties analyzed. From the evaluation of PL properties, there was an emission band centered at 420 nm in Ce:YSO samples. The observed emission originated from the 5d-4f transitions of Ce3+ ions. In OSL properties, OSL spectra under stimulation at 520 nm exhibited emission peaks at 420 nm, and the emission origin was also the 5d-4f transitions of Ce3+ ions. The OSL dose response functions had a lower detection limit of 1 mGy for the 0.5 and 1.0% Ce:YSO samples, and 10 mGy for the 0.1 and 2.0% Ce: YSO samples. The OSL intensity of the 1.0% Ce:YSO sample was approximately 69.3% after 24 h from X-ray irradiation compared to immediately after X-ray irradiation.

Published: August 2023

Abstract
We fabricated hybrid composites, where various organic–inorganic layered perovskite-type compounds (C6H5C2H4NH3)2PbBr4, (C6H5CH2NH3)2PbBr4, and (C4H9NH3)2PbBr4 were incorporated into a nanoporous glass, and their photoluminescence and scintillation properties were investigated for fast scintillator applications. A photoluminescence peak derived from free excitons was observed at around 410 nm for all the samples. Furthermore, a sharp scintillation peak originating from excitons was detected from the hybrid composites with (C6H5C2H4NH3)2PbBr4 or (C6H5CH2NH3)2PbBr4, and the hybrid composite with (C6H5C2H4NH3)2PbBr4 showed the highest scintillation intensity. In addition, afterglow levels of the fabricated hybrid composites were 430–620 ppm, and the values were higher than that of a (C6H5C2H4NH3)2PbBr4 single crystal.

Published: August 2023

Abstract
In-plane cluster arrangements of a long-period stacking ordered (LPSO) structure in MgYCu alloys were examined by reverse Monte Carlo fitting of small-angle X-ray scattering (SAXS) intensities. In situ SAXS measurements were performed at a heating rate of 10 K min−1. from the glass state to the mp. The clusters were characterized as so-called L12 clusters commonly observed in the LPSO structures. The results suggest that the average in-plane distance of the clusters decreased during heating. The distance showed two preferred average distances, in contrast to the MgYZn case where the average distance decrease monotonically during heating.

Diabetes Mellitus is a chronic metabolic disease characterized by elevated blood sugar levels and impaired carbohydrate, lipid, and protein metabolism due to betta pancreatic-cell dysfunction or insulin resistance in body cells. The prevalence of diabetes mellitus continues to increase worldwide. Indonesia itself has a prevalence of type 2 diabetes mellitus reaching 90% of all diabetes (WHO, 2016) (Riskesdas, 2018). The management of type 2 diabetes mellitus is very diverse, ranging from non-pharmacological therapy to pharmacological therapy such as insulin injection and oral anti-diabetes. Each anti-diabetic drug has a variety of ways of working, administration, and side effects. This study aims to analyze the comparison of the effectiveness of anti-diabetic medications based on blood sugar levels from the use of metformin and glimepiride (sulfonylureas) or a combination of both in patients with type 2 diabetes mellitus at Dr. Soewandhie Regional Public Hospital. This research is an analytic retrospective observational using secondary data in the form of medical records of patients with type 2 Diabetes Mellitus (outpatient) at Dr. Soewandhie Regional Public Hospital in 2019. The sample of this study consisted of 121 samples that met the inclusion criteria (43 patients on metformin therapy, 40 patients on glimepiride therapy, and 38 patients on combination therapy). The analysis of this study used data on FBG (Fasting Blood Glucose) before and three months after receiving metformin or sulfonylurea (glimepiride) therapy or a combination of both in the medical record. Data analysis of this study was performed using the Friedman test. This study showed that there was no significant difference in glycemic control (∆FBG) of metformin, glimepiride, and combination therapy in patients with type 2 diabetes mellitus (p value=0.575). There was no significant difference in the effectiveness of metformin, glimepiride, and combination therapy in patients with type 2 diabetes mellitus in Dr. Soewandhie Regional Public Hospital in 2019. In a study conducted in Japan showed that there’s efficacy of high-dose metformin use in patients with type 2 diabetes mellitus in Japan. The efficacy and safety of metformin are similar when used either twice daily or thrice daily. Further research needs to be done to assess the glycemic control (∆FBG) rate of metformin, glimepiride, and combination therapy in patients with type 2 diabetes mellitus by taking into account other factors such as medication adherence, diet, and physical activity.
