Peroral Endoscopic Myotomy (POEM) in a 19-Month-Old Girl with Primary Achalasia
Authors: Duman Serkan , Yurci Alper , Cho Joo Young 
Published: June 2023

Abstract
Introduction Primary achalasia is an idiopathic motility disorder of the esophagus characterized by esophageal aperistalsis and incomplete relaxation of the lower esophageal sphincter (LES) in response to swallowing. The gold standard diagnostic method in adults is high-resolution manometry (HRM). Diagnostic criteria in adults are also used in children, but some HRM normal values may change depending on age.
Case Report A 15-month-old girl was admitted to the hospital for evaluation due to persistent vomiting since birth. Vomiting included what she ate regardless of the amount of food she consumed. Barium esophagography revealed barium retention, esophageal dilatation, and a “bird's beak appearance” in the distal esophagus. Esophagogastroduodenoscopy revealed stenosis in the lower esophagus and bubbles at the esophagogastric junction.In HRM, the resting LES pressure was 43.4 mm Hg, there was pan-esophageal pressurization with 60% of swallows and no normal peristalsis. The patient was diagnosed with type II achalasia based on the Chicago 3.0 classification.First, the tube was inserted to ensure adequate nutrition of the patient, and approximately 4 months later, when the patient was 10 kg, the peroral endoscopic myotomy (POEM) procedure was performed.No complications developed during and after the procedure. At the 6th month after treatment, the patient was completely asymptomatic and her weight was within normal limits for her age.
Conclusion POEM is an effective and safe method in the treatment of pediatric patients with idiopathic achalasia.

Published: June 2023

AbstractThis study developed and validated the indicators of school internationalization in elementary and secondary schools in Taiwan to identify their level of internationalization and assess how the same has been implemented in these institutions. The data for the study was obtained from focus group interviews with 14 school internationalization experts and 176 school principals. Subsequently, 145 sample schools were recruited to complete an online questionnaire as part of a formal survey. The 20-item indicator scale regarding internationalization goals, campus internationalization, personnel internationalization, administration internationalization, curricula internationalization, and international partnerships proved suitable to orient elementary and secondary schools in Taiwan toward establishing international environments. Furthermore, results have important implications that the government should provide additional financial support and educational resources to reduce the teacher turnover rate and increase the willingness of schools in Taiwan to participate in international affairs.
The relationship between criminology and criminal law: implications for developing Chinese criminology
Authors: Shuai Honglan , Liu Jianhong 
Published: June 2023

AbstractDuring the last four decades, Chinese criminology has grown steadily but modestly. One consensus is the lack of a clear understanding of the relationship between criminology and criminal law. This paper attempts to provide a critical review of the relationship between the two disciplines by first tracing the historical development of criminology in both China and Western countries. It then clarifies the distinctions and overlaps between criminology and criminal law and explains how this relationship has influenced the growth of criminology in China. It concludes by proposing implications for developing criminology in China, particularly discussing potential collaborations that could be forged between criminology and criminal law and how such partnerships can benefit both fields in China.

Published: June 2023

Context Understanding the factors that influence viable-seed production is crucial in the conservation of threatened plant species, yet these factors are often poorly understood. Aims We investigated the reproductive biology of Zieria granulata C.Moore ex Benth., an endangered Australian endemic with a limited distribution, with the intent of improving conservation and restoration outcomes. Methods Components of floral biology, including floral ontogeny and nectar production, were quantified to determine the pollination syndrome and the likely breeding system. Flower-visitor surveys (using both digital video recordings and human observations), a manipulative wind-pollination experiment and hand-pollination experiments were conducted to investigate pollination vectors and confirm the breeding system. Key results Z. granulata flowers were small, white, protandrous and produced highly ornamented pollen grains and small quantities of nectar; these characteristics suggest that the species fits the general entomophily syndrome. All floral visitors were arthropod species and of the 72 visitors observed, predominantly from the Dipteran and Hymenopteran families, 18 could be regarded as potential pollinators. Failure of simulated wind gusts (40 km h−1) to transport pollen ≥5 cm indicated that anemophily is unlikely for this species. Autonomous and manipulative selfing did not result in viable seed set, indicating that this is an obligate outcrossing species. However, fruit and viable-seed production was highly variable within and among some other treatments. Pre-dispersal seed predation was recorded at all study sites. Conclusions Pre-dispersal seed predation was recorded at all study sites and is a likely factor inhibiting viable-seed production. Implications This knowledge will be used to improve seed yield for collections used for ex situ conservation and restoration programs for the endangered Z. granulata.
Acoustic Emission Behavior of TATB Based PBX during Uniaxial Compression Deformation
Authors: Xiao Pan , Li Haining 
Published: June 2023

Abstract
In order to study the feasibility of acoustic emission technology for the damage and fracture monitoring of TATB-based PBX materials and components, the acoustic emission characteristics of notched and unnotched specimens under uniaxial compression were studied. The results of uniaxial compression and step-cycle compression experiments of unnotched specimens showed that there were few AE hits with low amplitude under low strain stage and many AE hits were generated when the specimen failed. In addition, the Kaiser effect is applicable at the low load stage. In addition, there were less AE hits in initial loading stage for the specimen with notches, which may be caused by machining force. However, very strong AE hits were generated in the specimen with notches before macroscopic fracture occurred. Acoustic emission technology can be used to determine whether macroscopic cracks were generated in TATB-based PBX structures in the experiment.

Abstract
In order to select the binder suitable for FOX-7 polymer bonded explosives system, the binding energy and mechanical properties of FOX-7 with three binders were calculated by molecular dynamics method. The results show that the binding energies of the three systems are in the order of FOX-7+BA> FOX-7+F2603> FOX-7+EVA, and that the binding energies of F2603, BA with FOX-7 are basically the same. FOX-7+F2603 and FOX-7+ BA systems exhibit better comprehensive mechanical properties, and thus are more suitable for polymer bonded explosive systems.

Published: June 2023

Abstract
3D printing technology provides a new technical approach for the preparation of complex-type gun propellants. The filling pattern chosen for printed gun propellants has an impact on the mechanical strength of gun propellants. In this paper, three filling patterns were used to print the gun propellant samples. There is axial, radial and 45° straight filling pattern. The tensile and compressive strength of samples with different filling patterns were compared and studied. The result shows that the tensile strength of samples printed with 45° straight filling pattern is the largest, and the compressive strength of samples printed with the radial filling pattern is the largest. The filling pattern has a significant effect on the mechanical strength of 3D-printed gun propellants.

Published: June 2023

Abstract
To represent the temperature and degree of cure (DOC) more intuitively during the curing process of fiber-wound composite shell, wrote SDVINI, DISP, FILM, and HETVAL subroutines to characterize the fiber-wound composite curing process in ABAQUS. Comparing the temperature and DOC. The results indicate that the heat released from the resin curing process affects the internal temperature of the material, but the effect is small and can be ignored. The DOC on the surface of the fiber-wound shell during the curing process is slightly larger than that inside, but the difference is small and can be approximated as equal. And when the curing time is the same, the faster the heating rate, the faster the curing rate.

Abstract
This paper presents a solution for a tunable broadband terahertz radiation source, which can be realized by a newly designed BWO (Backward Wave Oscillator) using slow-wave structure with dual waveguide-loaded gratings. Gratings in two rows of the same height operate in different frequency ranges. Additionally, the signal-to-noise ratio within the operating frequency has been dramatically improved by placing a lossy material at the end of the waveguide. The operating frequency of the double gratings alternate from 185.63 GHz to 239.6 GHz and 244.08 GHz to 291.93 GHz accordingly. Ultimately, the relative bandwidth of the whole device reaches 41.7%.

Structural response analysis of free rigid-perfectly plastic warhead under three typical transverse loads
Authors: Ming Ke , Ruyu Fan , Gang Zhou , Kun Ma , Yusong Zhang 
Published: June 2023

Abstract
Based on the rigid-perfectly plastic assumption, the structural response of a free warhead under the application of concentrated force, evenly distributed force, and ramping-up force was analysed, taking the geometrical features into account. By the sectional shear force and bending moment distribution, the critical section was determined through a yield criterion based on the fully plastic bending moment. It shows that when the load is applied at the tip of the warhead, singularity occurs in the yield function at the tip, but vanishes when the applying (or starting) point of the load some distance away. The influence of the distance of the applying (or starting) point to the tip was also discussed, and was found to be important in determining the location of the critical section. As the applying (or starting) point moves away from the tip, the critical section appears near the tip first, then jumps to the cylinder part of the warhead, and when far enough, jumps back to the head of the warhead in the concentrated force case, while in the distributed force cases the critical section appears first at the cylinder part, and then jumps to the head. The critical section jumps to the head much earlier and more localized around the connecting point of the head and the cylinder in the ramping-up case than in the evenly distributed case.

Authors: Xu Hengwei , Liang Bin , Liu Junxin , Lu Yonggang 
Published: June 2023

Abstract
To study the effect of off-axis initiation on shaped charge performance. The nonlinear finite element software LS-DYNA is used to simulate the jet forming and armour-breaking process under different initiation offsets (0.025~0.125Dk, Dk is shaped charge diameter). A theoretical model is established to analyse the lateral velocity distribution of jet. The results show that the degree of asymmetric collapse and lateral velocity of jet increase with the offset. When the initiation offset exceeds 0.025Dk, the jet penetration capability of shaped charge jet will be seriously weakened.

Published: June 2023

Abstract
Aiming at the problem that the gun barrel vibration affects the firing accuracy during tank moving, based on the road simulation test, under the excitation of the different road levels (C, D and E), the acceleration vibration response curves of the barrel under different road levels and different vehicle speeds were obtained by arranging acceleration sensors on the barrel surface. Based on the power spectrum analysis method, the frequency response characteristics of the barrel vibration were analyzed, and the main frequency of barrel vibration during moving is obtained. It has been shown that, the main frequency of the barrel response is mainly distributed in three frequency ranges: 1~3Hz, 14~15Hz and 24~26Hz. The main frequency of the barrel vibration is different with different roads. The main frequency of the barrel response is mainly in the frequency range of 1~3Hz under C level road, and in the frequency range of 1~3Hz and 24~26Hz under D lever road. And under the E level road, the main frequency of barrel response is within the three frequency ranges of 1~3Hz, 14~15Hz and 24~26Hz. And the main frequency is 25Hz as the measuring point is far away from the muzzle. The results will provide support for obtaining the vibration characteristics of barrel as tank moving and explaining the vibration response law of the barrel.

Abstract
Praline chocolate usually contains soft fillings such as water-based filling from fruits. The interaction between water in chocolate filling and fat in praline shell formulation is interesting to be studied. Water in the water-based filling may migrate to the chocolate shell and thus influence chocolate quality. The aim of the study was to physically investigate the impact of duration of shell formation during manual tempering process on the characteristics of couverture praline chocolate filled with blueberry filling. The variables used in this study was shell formation duration (10, 15, 20 minutes), and duration of crystal maturation (day 0, 4, 8, 12). Chocolate shell was formulated with sucrose and 34% of fat content. The result showed that the longer the shell formation, the higher the chocolate hardness and particle size. While, chocolate lightness ranged between 25.47 to 27.57.
