Authors: Alvarez-Bautista Francisco E. , Hoyos-Torres Alejandro , Sarre-Lazcano Catherine , Andrade-Rojas Juan J. , Salgado-Nesme Noel 
Published: June 2023

Abstract
Introduction Intussusceptions in adults are rare, representing 1% to 5% of intestinal obstructions in this age group. This condition can be caused by benign and malignant lesions acting as lead points, the latter being the most frequent. Furthermore, the diagnosis is challenging due to the non-specific symptoms with variable duration.
Case Presentation A 43-year-old man, with a history of localized clear-cell renal carcinoma (ccRCC) treated 9 years earlier with a right radical nephrectomy, presented with bowel obstruction symptoms. An abdominal computed tomography scan showed an ileocolonic intussusception. Hence, the patient required a right hemicolectomy with ileotransverse anastomosis. The histopathological analysis showed a metastatic ccRC to the terminal ileum causing the intussusception.
Discussion Adult intussusceptions are rare. However, they should be considered in the differential diagnosis of patients with abdominal pain and symptoms of bowel obstruction. Metastases of renal cancer to the small bowel are uncommon and even more so in the form of intussusception. Definitive treatment must be tailored to the patient's condition and underlying cause.

Abstract
Background Anastomotic leakage (AL) is still the most annoying postsurgery complication after colorectal resection due to its serious complications up to death. Limited data were available regarding differences in AL incidence, management, and consequences for different types of colorectal resection.The aim of the present work was to evaluate differences in incidence of AL, incidence of postoperative complications, and length of hospital stay in a large number of patients who underwent elective colorectal resection for management of colorectal lesions. In addition to detect when and what type of reoperation for management of AL occur after colorectal resection.
Patients All 250 included patients underwent elective surgeries for colorectal resection with performance of primary anastomosis for management of colorectal neoplastic and non-neoplastic diseases in the period between May 2016 and July 31, 2021.We followed the patients for 90 days; we registered the follow-up findings.
Results the rates of AL occurrence were variable after the different procedures. The lowest rate of AL occurrence was found in patients who underwent right hemicolectomy, then in patients who underwent sigmoidectomy, left hemicolectomy, transversectomy and anterior resection (p = 0.004). A stoma was frequently performed during reoperation (79.5%) which was significantly different between different procedures: 65.5% in right hemicolectomy, 75.0% in transversectomy, 85.7% in left hemicolectomy, and 93.0% in sigmoid resection (p < 0.001).
Conclusion Rates, types, time of occurrence and severity of AL vary according to the type of colectomy performed and selective construction of stoma during AL reoperation is currently safely applied with comparable mortality rates for patients who did and who did not have a stoma after reoperation.

AbstractThe gold-standard procedure for anal canal examination is anoscopy. Nonetheless, patients are referred for a colonoscopy for many reasons, and a routine exam might provide an opportunity to diagnose anal pathologies, such as hemorrhoids, anal fissures, anal polyps, condylomas, and anal squamous cell carcinoma. It is important to know the main features of these conditions and relevant information to report in order to help guide patient treatment and follow-up.

Published: June 2023

Fast and sensitive phase transition detection is one of the most important requirements for new material synthesis and characterization. For solid-state samples, microwave absorption techniques can be employed for detecting phase transitions because it simultaneously monitors changes in electronic and magnetic properties. However, microwave absorption techniques require expensive high-frequency microwave equipment and bulky hollow cavities. Due to size limitations in conventional instruments, it is challenging to implement these cavities inside a laboratory cryostat. In this work, we designed and built a susceptometer that consists of a small helical cavity embedded into a custom insert of a commercial cryostat. This cavity resonator operated at sub-GHz frequencies is extremely sensitive to changes in material parameters, such as electrical conductivity, magnetization, and electric and magnetic susceptibilities. To demonstrate its operation, we detected superconducting phase transition in Nb and YBa2Cu3O7−δ, metal–insulator transitions in V2O3, ferromagnetic transition in Gd, and magnetic field induced transformation in meta magnetic NiCoMnIn single crystals. This high sensitivity apparatus allows the detection of trace amounts of materials (10−9-cc) undergoing an electromagnetic transition in a very broad temperature (2–400 K) and magnetic field (up to 90 kOe) ranges.

Authors: Wang Yanfang , Hu Chencheng , Wang Dongbin 
Published: June 2023

In this work, the influence of Cr and Mn impurity atoms on the electronic structure and magnetic properties of 3C–SiC was analyzed by carrying out first-principles calculations using the GGA + U method, and the influence of Si vacancies on the co-doped system was also considered. The results showed 3C–SiC systems mono-doped with Cr and Mn atoms to be spin-polarized had total magnetic moments of 3.05 and 5.00 μB, respectively. The ferromagnetic state of each of various (Cr, Mn)-co-doped 3C–SiC systems was determined to be more stable than the antiferromagnetic state, with a magnetization energy of −702.3 meV for the most stable system and a total magnetic moment of about 6.00 μB. Finally, the effect of Si vacancies on the doping system was considered on the basis of (Cr, Mn) co-doping. The introduction of Si vacancies reduced the ferromagnetism of the (Cr, Mn)-co-doped 3C–SiC system. The calculations performed in this research have provided a theoretical basis for using (Cr, Mn)-co-doped 3C–SiC as a spintronic device.

Authors: Avagyan Arik , Knill Emanuel , Glancy Scott 
Published: June 2023

Abstract
The continuing improvement in the qualities of photon-number-resolving (PNR) detectors opens new possibilities for measuring quantum states of light. In this work we consider the question of what properties of an arbitrary multi-mode Gaussian state are determined by a single PNR detector that measures total-photon number. We find an answer to this question in the ideal case where the exact photon-number probabilities are known. We show that the quantities determined by the total-photon-number distribution are the spectrum of the covariance matrix, the absolute displacement in each eigenspace of the covariance matrix, and nothing else. In the case of pure Gaussian states, the spectrum determines the squeezing parameters.

Abstract
Organic–inorganic hybrid perovskite nanocrystals have become a very widely used as semiconductor light-emitting materials. However, perovskite nanocrystals face stability challenges, which is a key factor hindering their application. In this paper, by introducing water into the synthesis of formamidinium lead bromide (FAPbBr3) perovskite, ultra-stable FAPbBr3@PbBr(OH) fluorescent material was prepared. The photoluminescence intensity of the material after the addition of water increased 2.9 times compared with that before the addition of water. The excellent green fluorescence emission was still maintained after four cycles of wash–dry treatment. Meanwhile, it also exhibits good ultraviolet and thermal stability. The above enhanced performance of FAPbBr3 nanocrystals is attributed the protection of PbBr(OH). In addition, the prepared material can be used in anti-counterfeit patterns. The anti-counterfeit patterns have good color rendering and the luminous color has a high dependence on temperature. Both of these features make it very valuable for various fluorescent anti-counterfeiting labels.

Published: June 2023

Abstract
How to efficiently share secrets among multiple participants is a very important problem in key management. In this paper, we propose a multi-secret sharing scheme based on the Greenberger Horne Zeilinger (GHZ) state. First, the distributor uses monotone span program to encode the secrets and generate the corresponding secret shares to send to the participants. Then, each participant uses the generalized Pauli operator to embed its own secret share into the transmitted particle. The participant who wants to get the secrets can get multiple secrets at the same time by performing a GHZ-state joint measurement. Furthermore, since this scheme is based on a monotone span program, its access structure is more general than the access structure (t, n) threshold. Compared with other schemes, our proposed scheme is more efficient, less computational cost.
Detection of a target hidden in dense cloud clutter using an echo pattern of pulsed laser radar systems
Authors: Bahmeh Zahra , Zangeneh Hamid Reza 
Published: June 2023

Abstract
The performance of pulsed laser radar systems has been known to be drastically reduced in dense clutter media, detecting false signals instead of the target. Therefore, high-performance laser radars have become demanding for detection applications. Here, using a multi-scattering Monte Carlo simulation, the pulsed laser radar performance is studied in dense cloud clutter (DCC), involving the role of the clutter extinction coefficient in the cloud return signal waveform of the target. After generating a large number of return signals from the clutter and the target, a unique and prominent feature is found to efficiently distinguish the two signals from each other with a resolution of 0.80 and a minimum signal to clutter ratio of 5.04 dB. A high-pass trapezoidal filter is also designed based on the characteristic feature in order to eliminate the clutter return signal. This proposed filtering method is justified by applying Fourier transform to the return power from the target and cloud, eliminating the clutter frequency response in a low frequency region. Accordingly, it is possible to detect a target hidden in DCC at short distances through receiving an echo pulse pattern.

Published: June 2023

Abstract
There are many varieties of new developed energetic materials with different capabilities of shock wave pressure action. In order to effectively evaluate the explosive damage power of diverse energetic materials and to make the evaluation model universal, the TNT is used as the basic material, and the evaluation model of the explosive pressure action of energetic materials is established in this paper based on the nonlinear fitting method. Explosion tests of TNT with different charge quantities are carried out under the same test conditions, and the shock wave surface reflection pressure data at different proportional distances are obtained. The evaluation model between the peak pressure of the TNT shock wave and the proportional distances is constructed based on the explosion similarity ratio formula using the nonlinear fitting function. The prediction accuracy of the established model is verified by the typical TNT charge test, and the proposed model is applied to evaluate the explosive pressure effect of energetic materials. Experimental results show that the predication accuracy of the evaluation model for evaluating the explosion shock wave pressure action of energetic materials based on the nonlinear fitting method is higher than 86.5067%, which can meet the requirements of the engineering applications.

Published: June 2023

Abstract
Strength is an important characteristic of material mechanical properties. Based on the microcrack model and considering the internal friction effect between the crack surfaces, the uniaxial tensile and compressive strength theoretical model which can reflect the tensile and compressive anisotropy of materials is derived and established by using the crack initiation criteria of maximum circumferential stress and maximum circumferential strain, considering the internal friction coefficient and Poisson’s ratio. By introducing the TATB based PBXs parameters, the tension compression ratio of PBXs calculated by using the maximum circumferential stress and strain criteria are 0.293 and 0.471 respectively, with errors of -10% and 44% respectively compared with the experimental value of 0.326; The calculated failu re angles are 29.52 ° and 19.44 ° respectively. Compared with the experimental values of 24 ° and 30 ° (average 27 °), the errors are 9% and -28%, respectively. The analysis shows that the maximum circumferential stress criterion is more suitable for the construction of PBXs strength criterion based on microcrack model.

Published: June 2023

Abstract
In this paper, numerical simulation is used to study the buffer layer material, thickness and structure on the reactive fragment load and its action time under blast impact loading conditions. The results show that the buffer layer can significantly reduce the peak pressure of the detonation wave acting on the reactive fragment and prolong the action time; the buffering capacity of different buffer materials is different; for the same material, the buffering capacity is proportional to the material thickness; compared with a single layer of buffer layer, the buffer layer with the same thickness and composite structure has a stronger capacity.

Abstract
Blast wave will be generated in concrete when hit by projectiles at a high velocity. Such blast wave will severely threaten structures. The impact acceleration on the structure surface is an instinctive indicator of the propagation of blast wave, since the acceleration is closely linked to the penetration and explosion state of the warhead. This paper conducted acceleration measurement and analysis on the penetration and explosion of penetration warheads on reinforced concrete target. In addition, test results, on-board testing results and numerical results have been compared to analyze the damage process and mechanism of the target, providing basis for warhead design, target design, simulating calculation and damage efficacy evaluation.

Authors: Gu Xudong , Zhao Bingxin , Gao Ruolin , Yang Yongfeng , Liu Yuhao 
Published: June 2023

Abstract
In the present paper, the dynamical response of a cantilever beam with fractional damping excited by the moving mass load is studied. First, the vibration equation of the cantilever beam is established by adopting Euler-Bernoulli beam theory. Then, the established equation is discretized by using Galerkin discretization. The discrete equation is difficult to solve due to the fractional damping. Based on the generalized harmonic function technology, the fractional damping force is approximated by a damping force and a conservative force. Then, an efficient algorithm is used to calculated the truncated equation to derive the dynamical response. The displacement at the end of the cantilever beam is calculated, and the influence of fractional damping coefficients is analysed.

Abstract
Praline is a type of chocolate with fat-based and water-based filling. This chocolate is becoming more popular in Indonesia and gaining intentions of small-scale chocolate producers. In this study, couverture praline chocolate with water-based filling was produced using manual method. The aim of this study was to investigate the best treatment to create the most stable praline shell filled with carrageenan-based hydrogel. The variables used in this study was duration of shell formation (10, 15, 20 minutes) during manual tempering process. Chocolate characteristics, namely hardness, colour and particle size were measured at day 0, 4, 8, 12. The result showed that chocolate hardness increased as the duration of shell formation also increased. Chocolate lightness was decreased as the duration of crystal maturation increased. Whereas, particle size was relatively high and tended to fluctuate.
