AbstractBackground: Stigma is a trait, belief, or disgrace where a mentally ill person is socially defamed in certain manners. Stigma can cause great psychological distress among the caregivers of patients with psychiatric illness.Aim: The study was aimed to assess the level of stigmatized attitude toward mental illness among the caregivers.Materials and Methods: A cross-sectional study design was used to collect data among 210 caregivers of patients with psychiatric illness who were recruited using purposive sampling technique. Baseline proforma and stigmatizing attitude scale were used to collect the data.Results: The findings depicted the mean age of the caregiver was 44 years. More than half number of subjects (54.3%) were females. Majority (90.44%) of the caregivers had moderate, whereas 3.33% had low stigmatizing attitude with the mean ± standard deviation was 52.77 ± 9.91. Chi-squared test showed no significant association between stigmatized attitude score and selected demographic variables.Conclusion: It is vital that awareness programs and antistigma campaign can be initiated in the community settings, with the help of interdisciplinary coordination and collaboration of the health care members to eradicate the stigmatizing attitude among the caregivers.

Authors: Beshyah Waleed S. , Alsaffar Hussain , Beshyah Salem A. 
Published: September 2022

Objectives To assess the perceptions of genetic and metabolic bone disorders with a focus on X-linked hypophosphatemia (XLH) in the Middle East and Africa.
Materials and Methods An online survey of a convenience sample of physicians from relevant disciplines. The questions covered respondents' profiles, awareness of rare bone diseases, and XLH's burden, symptoms, and management.
Results A total of 139 respondents were included in the analysis. Responses came from the Arabian Gulf (41.7%), Middle East (20.1%), North Africa (17.3%), and Sub-Saharan Africa (20.9%). The largest single specialty was endocrinology (41%). When asked, 16 (11.5%) could not know about any metabolic/genetic bone diseases, and 123 respondents (88.5%) stated that they could think/were aware of some metabolic/genetic bone diseases, 111 enumerated various genetic and metabolic disorders. When they were presented with a typical case scenario of XLH, 18.0% of the respondents admitted ignorance of any possibility. However, 82.0% indicated having some idea of the condition. Of the latter group, 109 provided suggestions for possible diagnosis; the top single diagnosis was XLH. A smaller proportion of adult physicians had patients with symptoms attributed to XLH. Around three-quarters of respondents were aware of conventional therapy for XLH with vitamin D and phosphate supplementation. However, 89.8% of respondents welcomed specific biological therapy.
Conclusions Physicians are reasonably aware of XLH but have variable knowledge. They are unsatisfied with its conventional treatment. More in-depth knowledge of recognizing and modern management of bone metabolic and genetic conditions should be enhanced, particularly among adult physicians.
High-Grade Biphenotypic Sinonasal Sarcoma: A Case Report
Authors: Hasnie Sukaina , Glenn Chad , Peterson Jo E. G. , El Rassi Edward T. , McKinney Kibwei A. 
Published: September 2022

Abstract
Introduction Biphenotypic sinonasal sarcoma (BSNS) is a recently found entity that first described by Lewis et al. It was then added to the 4th edition of the World Health Organization (WHO) of head and neck tumors in 2012. BSNS has been described as a rare low-grade sarcoma arising in the upper sinonasal tract. It is believed that in the past, BSNS was, likely, previously diagnosed as other low-grade or benign malignancies. Fibrosarcoma, leiomyosarcoma, and peripheral nerve sheath tumors, all fall within the differential diagnosis of BSNS. However, BSNS is unlike other mesenchymal sinonasal tumors, as it displays both neural and myogenic differentiation. BSNS has thus far been recognized in only a hand full of case reports, all of which have reported similar morphologic features of a low-grade soft tissue tumor with neural involvement arising from the nasal cavity or ethmoid air cells in middle aged individuals. In fact, being low-grade sarcoma became such a hallmark characteristic of this tumor that it even received the name low-grade sinonasal sarcoma with neural and myogenic features or LGSSNMF.
Case Presentation We present, however, for the first time, a high-grade differentiation of BSNS in an otherwise healthy 72-year-old female. The patient was referred from an outside ENT (ear, nose, and throat) after pathology from a presumed polypectomy returned positive for a BSNS. Initial imaging revealed erosion through the bilateral lamina papyracea, anterior cranial fossa floor, and posterior table of the frontal sinus. She then underwent a combined endoscopic and bicoronal open approach for resection of the skull base lesion that was found to encompass the entirety of the sinonasal cavities bilaterally. Postoperatively, the patient underwent significant complications including infection of the pericranial flap, pneumocephalus, and eventually death.
Discussion As BSNS is a fairly new entity, currently there has only been four case series conducted, each identifying features of a low-grade sarcoma with both myogenic and neural differentiation. Histologically, BSNS has monophasic spindle cells with uniform, elongated nuclei with scant cytoplasm between benign proliferations of surface-type respiratory epithelium, with a low mitotic rate. Our case, however, revealed pleomorphic hyperchromatic cells with high mitotic activity and necrosis with invasion of bone, staging it as high grade. Immunohistochemistry also differed from the previously reported standards. This case describes a new category for BSNS which may change the differential diagnosis, management, and surgical recommendations that are currently utilized for this skull base neoplasm.

Published: September 2022

Negative central magnetic shear or magnetic shear reversal is an attractive aspect for advanced operation scenarios in tokamaks as it suppresses turbulence and facilitates the formation of internal transport barriers (ITBs). The advanced operation scenario with negative magnetic shear, which is associated with high confinement quality, a large bootstrap fraction, ITBs, and so on, is one of the future goals of the experiments on EAST. In this work, modeling efforts have been made to find the operation regimes on EAST with negative central shear and large-radius ITBs. The modeling results indicate that negative central shear and large-radius ITBs can be achieved when the electron density is 〈ne〉/nG &gt; 0.7 and the off-axis deposited electron cyclotron heating (ECH) power is 2 MW. Additionally, scenarios with lower ECH power (∼1.5 MW) have been studied since at present, the maximum ECH power that can be provided on EAST is 1.5 MW. With a lower off-axis ECH power of 1.5 MW, scenarios with negative central shear and large-radius ITBs but with a higher electron density of 〈ne〉/nG &gt; 0.8 are obtained. The same as the first case, if the electron density is reduced to 〈ne〉/nG = 0.8 in this case, large-radius ITBs disappeared in the predicted scenario. This reveals that high electron density and large off-axis deposited ECH power are important for scenarios that have q-profiles with negative central shear and large-radius ITBs since lower hybrid current drive (LHCD) tends to peak near the axis at lower electron density, and hence, it helps to increase the temperature gradient near the axis, which will promote bootstrap in this region, leading to a centrally peaked total current density profile. Higher off-axis deposited ECH power helps to obtain scenarios with strong negative central shear and large-radius ITBs at a lower density. Scenarios predicted in this work will guide future experiments on EAST.

Published: September 2022

Many aspects of our daily lives are affected by the generation of water droplets, and it is important to controllably produce droplets with a wide size range in various applications. In this paper, we describe an on-demand droplet generating system based on a high-speed two-way solenoid valve. A nozzle made of stainless steel tubing is fit into one port of the valve, and the other port is connected to the fluid reservoir by which the pressure can be controlled via a pressure regulator. When the liquid is pressurized and the valve is opened with a short pulse voltage, trace amounts of liquid will be ejected from the nozzle to form a droplet. Droplet generation is captured using a high-speed camera to measure the dimension and velocity and to evaluate the performances of the generator, such as repeatability and stability. We demonstrate the influences of applied pressure and pulse width of driving voltage on droplet generation. It is shown that the droplet generator is capable of producing droplets in a wide size range for a given nozzle (e.g., about 0.7–2.2 mm for a 1.0 mm diameter nozzle). A single droplet is stably generated at Z = 268.1, obviously higher than the published data and the Weber number of a fluid jet (Wej) ranging from 2.1 to 5.6. The droplet generator presented here will be useful for research related to large droplets, such as freezing rain in atmospheric science and supercooled large drops in aircraft icing.
Calculation of magnetic forces and torques on the Kibble coil

Published: September 2022

Abstract
Analytically the force acting on a current-carrying coil in a magnetic field can be calculated in two ways. First, a line integral can be conducted along the coil’s wire, summing up the differential force contributions. Each contribution results from a cross-product of the corresponding differential line segment with the magnetic flux density at that location. Alternatively, the coil’s energy in the field is given as a product of three factors, the number of turns, the current, and the flux threading the coil. The energy can then be obtained by executing a surface integral over the coil’s open surface using the scalar product of the differential surface element with the magnetic flux density as its integrand. The force on the coil is the negative derivative of the energy with respect to the appropriate coordinate. For yoke-based Kibble balances, the latter method is much simpler since most of the flux is contained in the inner yoke of the magnet and can be written as a simple equation. Here, we use this method to provide simple equations and their results for finding the torques and forces that act on a coil in a yoke-based magnet system. We further introduce a straightforward method that allows the calculation of the position and orientation difference between the coil and the magnet from three measurements.

Published: September 2022

Abstract
In orbit deployment and profile maintenance are the most important functional requirements in the development of loop antenna If the antenna cannot be deployed in orbit, it will lose the signal transmission function, and the profile in orbit holding function is related to whether the antenna can stably transmit electromagnetic signals. The mesh tension (main mesh tension, rear mesh tension and tension arrays tension) is the key means to maintain the profile stability in orbit. At the same time, it is also closely related to the rod load and the maximum motor driving force in the process of antenna deployment. Based on the theory of flexible multi-body dynamics, the dynamic modeling of the deployment process of ten meter loop deployable antenna is established in this paper On this basis, the influence of mesh tension on the deployment dynamics of loop antenna is analyzed by using the control variable method, and its related variation law is obtained. This study can provide guidance for the tension adjustment in the profile adjustment stage of the ring antenna, so as to shorten the development cycle, and can also predict the deployment of the antenna in orbit.

Published: September 2022

Abstract
Al-18Si-X (X=Mg, Ti, Ni) composite tubular castings were prepared by centrifugal casting. The microstructure of cylindrical casting of Al-18Si-X composite was observed along the radial direction, and the segregation behavior and distribution characteristics of primary particles formed in different alloys under the action of centrifugal field were studied. The results show that the in situ particles in Al-18Si-7Mg, Al-18Si-7Ti, and Al-18Si-7Ni tubular castings have different segregation behaviors under the action of centrifugal field, which results in the formation of particle reinforcing layers in different regions of the castings. It is found that the volume fraction, size and particle morphology of primary particles in particle reinforcement layer of different castings are different.

Published: September 2022

Abstract
The coating process in ceramic stereolithography is one of the principal sources of inaccuracy in the height dimension. The coating in stereolithography is a layer-by-layer build-up process, so the thickness of one layer coated is influenced by the previous layer and affects the thickness of the next layer. If inconsistent layer thicknesses exist, they will result in the poor quality of the final product. This paper analyzes the coating process of the slurry-separated system based on a simple 2D model and Navier-Stokes equations, presenting the theoretical equations of layer thickness for the commonly used blade types. Given the characteristics of layer-by-layer coating in stereolithography, the theoretical equations should be constantly iterated to obtain the thickness of each layer. This paper discovers the initial blade gap has a significant impact on the layer thicknesses by theoretical analyses. With the verification of experiments, the results shows that the presence of the unreasonable initial blade gap may lead to large fluctuations in layer thicknesses of the first few layers, and the coating in stereolithography is a "self-regulating" process with a tendency to the desired thickness. The larger the desired layer thickness, the worse this "self-regulating ability" is. This paper defines a coefficient of blade gap and proposes that using the coefficient of blade gap to determine a reasonable initial blade gap based on different working conditions can effectively control the consistency of each layer thickness.

Published: September 2022

Abstracts
Metallographic analysis is one of the means of testing and analyzing materials. To conduct metallographic analysis, we must prepare samples that can be used for microscopic observation. It is important to select and prepare representative samples, which is directly related to the correctness of microstructure analysis of metallography apspecimensimen. In this paper, the preparation process of the ferrocarbon alloy metallographic sample was analyzed and studied in detail, and some common defects were pointed out. The preparation process includes sampling, inlaying, polishing, polishing, and corrosion. Then, taking a silicon aluminum alloy (YZAlSi10) as an example, the preparation process is described, and the matters needing attention in the preparation process and the elimination of metallographic defects are analyzed. Finally, the accurate and clear microstructure of the metallographic structure is restored.
Annealing hardening behaviour of cold rolled Al0.5CoNiCu high-entropy alloy
Authors: Xia ChangMing , Bu LePing , Zhou Qi 
Published: September 2022

Abstract
The usually, softening occurs when metals are annealed, while for some special metals or alloys, the abnormal phenomenon of annealing hardening will occur. By means of X-ray diffraction (XRD), metallographic (OM) observation, transmission electron microscopy (TEM) and hardness test, the microstructure and hardness of 79% cold rolled Al0.5CrFeCoNiCu high entropy alloy was studied after isothermal annealing for 1 hour at different temperatures, which revealed the cause of annealing induced hardening of the alloy. The results show that the homogenized high-entropy alloy is a face centered cubic (FCC) biphasic structure with close lattice constant. After annealing at 300-750°C, the microhardness of the alloy is higher than that of the cold rolled alloy (399hv); With the increase of annealing temperature, the hardness increased first and then decreased. After annealing at 500 °C for 1 hour, the hardness reached the peak (489hv). XRD phase analysis shows that the alloy will precipitate body centered cubic (BCC) phase when annealed at 500-950°C and precipitate σ phase when annealed at 700-850 °C; In addition, when annealed at 650°C and above, the dislocation recovery speed in FCC phase is accelerated and recrystallization will occur, resulting in rapid softening of the alloy. TEM observation showed that there were L12 nano-precipitates with ordered structure in the FCC phase of the matrix. Therefore, the reason for the hardness peak of the alloy annealed at 500°C is the joint action of dislocation strengthening and precipitation strengthening (L12 and BCC phases).

Abstract
The M2052 (Mn-20Cu-5Ni-2Fe, at%) damping alloy specimen was prepared by laser melting deposition (LMD). And we studied the mechanical properties and microstructure of M2052 alloy. Columnar dendrite penetrating multiple cladding layers appeared in the as-deposited sample, and the size of dendrite tends to coarsen with the increase of laser power. Microsegregation and martensitic transformation occurs in the as-deposited M2052 alloy. The tensile strength of samples in different directions under the same process, and in the same direction under different processes is all exceeds 500 MPa. The fracture surfaces exhibit intergranular fracture model. This work shows great potential for fabricating Mn-Cu based damping alloy by LMD technology.

Abstract
We present a fundamentally different approach to process the bimodal Ti-based alloy (Ti-Nb-Fe-Co-Al) by semi-solid sintering stemmed from hypoeutectic reaction, aiming at achieving ultrafine eutectic structure, β-Ti and micron-sized dispersed phase with strengthening effect. As expected, the microstructure of the processed Ti-Nb-Fe-Co-Al alloy contains local ultrafine eutectic structure (β-Ti and TiFe), residual equiaxed β-Ti and micron-sized dispersed phase Ti2Co. This alloy possesses excellent properties, the yield strength is 1620MPa and large plastic strain is 20%, superior to those of the previous fully eutectic alloy by casting. The novel idea is helpful to fabricate high-performance alloys and metals, which belonging to high temperature alloy systems.
Design and implementation of an analog signal isolation conditioning circuit
Authors: Ling Yunzhi 
Published: September 2022

Abstract
In control systems, external analog signals need to be converted into digital signals. When sampling external input analog signals, such as voltage or current, it is necessary to process the small analog signal amplification or large signal reduction to the digital signal that can be sampled normally by the ADC; at the same time, the complexity of the external environment will affect the accuracy of sampling, and the input and output isolation processing needs to be carried out. Therefore, in order to solve the problem of low sampling accuracy of analog signal ADC in complex environment, this paper proposes an analog signal isolation conditioning circuit, which can filter out the high-frequency noise in the input signal without affecting the rapid sampling of the ADC, and use two-stage operation amplification to perform gain and zero compensation processing, so that the conditioned signal has high accuracy, good linearity, and strong anti-interference ability, which meets the design requirements. Through functional and stress tests, the functional correctness and performance stability of the analog signal isolation conditioning circuit proposed in this paper are verified.

Published: September 2022

Abstract
A novel type of interdigital sensor that has been introduced in this paper can non-destructively detect the thickness of insulating materials, e.g. tire. The sensor was manufactured by jet printing technology with high efficiency. The function of the developed sensor is based on the hindering effect on the transmission of electromagnetic signals. The thickness of the insulating materials can be therefore obtained by monitoring the degree of signal reflection through transmission. For optimization, sensors made with three recipes have been experimentally tested. It is concluded that the sensor with double layers’ structure possesses the optimal performances. Practically, the application of the developed sensor in detecting the wear of tire tread has been carried out.
