Published: November 2023

AbstractAn optimum electrode finger shape is obtained for the grating‐mode‐type SAW resonator on a 15° YX‐LiNbO3with a large relative bandwidth used for a high‐C/N broadband VCO. Spurious responses by Rayleigh wave need to be suppressed completely in the SAW resonator. Its impedance characteristics are extremely sensitive to the variations of electrode finger linewidth and film thickness. The specifications for the film thickness and linewidth of the electrode finger are derived by simulation and experiment. It is demonstrated that the electrode finger film thickness ofh/λ0= 0.1325 and the relative electrode finger linewidth ratio ofL/(L+S} = 0.575 are standard and their deviations need to be controlled accurately in fabrication. Assuming applications to industrial wireless terminals at 170 and 420 MHz, process accuracy enhancement is discussed so that the electrode finger specifications are satisfied. In the present SAW resonator with a thick electrode finger, an antireflection film is introduced in the photoresist process. Al‐Cu alloy is used for the electrode fingers to produce an excellent impedance characteristic. The VCO using the present SAW resonator satisfies the specifications of the above wireless terminals. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 84(9): 11–20, 2001

Published: November 2023

AbstractA new CMOS imager having a motion detection function has been developed. This CMOS imager can detect the motion of the image projected on a sensor array, scan automatically only a partial area including a place where the motion is detected as the focus. As a result, reducing the amount of data transfer and improving the frame rate have become possible. The detection of a moving body can be performed by motion detector circuits, which operate regardless of the frame rate. The motion detectors are sparsely placed in the sensor array to maintain the high pixel density. Other circuit techniques include the unity‐gain pixel amps, and a multistage readout circuit. A 5.8‐ × 8.7‐mm chip including 192 × 192 pixels and 7 × 7 motion detectors has been developed using a 0.35‐μm CMOS three‐layer metal process technology. Experimental results have successfully confirmed the functions of the chip. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 84(9): 28–35, 2001

Authors: Zeng Xiao , Yi Jing 
Published: November 2023

AbstractIn the context of globalization and digitization, supply chain information sharing and circulation have become important links in supply chain management. The current difficulty in sharing supply chain information is significant, and there are issues of information asymmetry and incompleteness among co participants. In order to improve the integrity and efficiency of supply chain information sharing and enhance the competitiveness of the high supply chain, this article conducts in‐depth research on the path of supply chain information sharing using Internet of Things technology. This article first analyzes the level of information sharing, influencing factors, and existing problems, then explores the Internet of Things technology, and finally establishes specific methods and means for the supply chain information sharing path through the Internet of Things technology. To verify the effectiveness of the supply chain information sharing path based on the Internet of Things, in this article, a comparison was made between the development effects of enterprise supply chains before and after applying the supply chain information sharing path based on the Internet of Things. The results show that after applying the IoT based supply chain information sharing path, the market price, production capacity, and market forecasting ability of enterprises have all increased by more than 20%. The conclusion indicates that the Internet of Things can help optimize supply chain information sharing and provide a new perspective for enterprise supply chain management and development.
Identification of N‐ and O‐Linked Oligosaccharides in Human Seminal Vesicles
Authors: ARENAS MARÍA I. , ROYUELA MAR , FRAILE BENITO , PANIAGUA RICARDO , WILHELM BEATE , AUMÜLLER GERARD 
Published: November 2023

ABSTRACTThe main oligosaccharide residues and the saccharide linkage in infantile and adult human seminal vesicles were studied by means of lectin histochemistry at light and electron microscopy levels. In adult glands, the epithelial cell cytoplasm and luminal content reacted positively to the following residues: (GlcNAc)n (WGA), Galβ1,3GalNAc (PNA), GalNAcα1,3Gal (SBA), GalNAcα1,3GalNAc (HPA), Fucα1,2Galβ1,4GlcNAc (UEA‐I), and αL‐Fuc1,6DGlcNAc‐O‐Melibiose (AAA). The presence of intense staining in the luminal content suggest that glycoproteins containing these oligosaccharide moieties are secreted by epithelial cells. Adult epithelial cells also reacted to Neu5Acα2,6Gal (SNA), Neu5Acα2,3Galβ1,4GlcNAc (MAA), Galβ1,4GlcNAc (DSA), branched mannose chains (ConA), Man1,3Man (GNA), and Fucα1,2Galβ1,4GlcNAcFucα1,3GlcNAc (LTA) but reaction to these residues was weak (MAA, DSA, ConA, and LTA) or absent (SNA and GNA) in the gland lumen, which suggests that they belong to intracytoplasmic proteins. The chemical and enzymatic treatments used suggest that the residues recognized by SNA, MAA, PNA, DSA, HPA, and SBA belong to O‐linked oligosaccharides; those residues localized by ConA and GNA have an N‐glycosidic linkage, and those bound by WGA, LTA, UEA‐I, and AAA are linked to both N‐ and O‐oligosaccharides. In prepubertal seminal vesicles, reaction in the epithelial cell cytoplasm was similar to that observed in adults, except for GNA and HPA, which showed a weaker reaction. However, the lumen of prepubertal seminal vesicles showed intense reaction to WGA and SBA only. The chemical and enzymatic treatments suggest that the scanty glycoproteins secreted by the prepubertal glands belong to the mucin‐type.

Comparison of the outcomes of split thickness skin graft versus full thickness skin graft for closure of the radial forearm free flap donor site: A systematic review
Authors: Mosquera Camilo , Weyh Ashleigh , Malik Michael , Fernandes Rui , Bunnell Anthony , Nedrud Stacey 
Published: November 2023

AbstractBackgroundRadial forearm free flap (RFFF) donor site closure is traditionally performed with split thickness skin grafts (STSG), which can be associated with poor aesthetics, wrist stiffness, paresthesia, reduced strength, and tendon exposure. Full thickness skin grafts (FTSG) are potentially beneficial as they provide a more durable coverage, and the skin graft donor site can be closed primarily, which is more aesthetic. The aim of this systematic review is to compare the outcomes of STSG versus FTSG for closure of the RFFF donor site.MethodsA systematic review was performed, following Preferred Reporting Items for Systematic Reviews and Meta‐Analysis guidelines. The primary objective was to answer: do subjects undergoing RFFF harvest, utilizing FTSG to close the RFFF donor site, compared to STSG, achieve superior aesthetics at the RFFF donor site? Included papers compared FTSG and STSG with statistical data. Means were compared with t‐test and proportions with Fisher's exact test.ResultsThe initial search resulted in 1851 studies. After applying the inclusion/exclusion criteria, the search resulted in eight studies, with 366 total skin grafts, 197 STSG and 169 FTSG. Six studies evaluated aesthetics utilizing a Likert scale, with the scaled average aesthetic score for FTSG being 7.9/10 compared to 6.9/10 for STSG (p < .001). Tendon exposure was measured in five studies, with a rate of 13.1% for STSG versus 10.6% for FTSG (p = .555). No significant difference in function was observed, however, methods to quantify function were heterogeneous.ConclusionFTSG compared to STSG, resulted in statistically significant improved aesthetics, with comparable rates of tendon exposure and function.
Effects of approximations in analyses of beams of open thin‐walled cross‐section—part II: 3‐D non‐linear behaviour
Authors: Pi Y.‐L. , Bradford M. A. 
Published: November 2023

AbstractIn a companion paper, the effects of approximations in the flexural‐torsional stability analysis of beams was studied, and it was shown that a second‐order rotation matrix was sufficiently accurate for a flexural‐torsional stability analysis. However, the second‐order rotation matrix is not necessarily accurate in formulating finite element model for a 3‐D non‐linear analysis of thin‐walled beams of open cross‐section. The approximations in the second‐order rotation matrix may introduce ‘self‐straining’ due to superimposed rigid‐body motions, which may lead to physically incorrect predictions of the 3‐D non‐linear behaviour of beams. In a 3‐D non‐linear elastic–plastic analysis, numerical integration over the cross‐section is usually used to check the yield criterion and to calculate the stress increments, the stress resultants, the elastic–plastic stress–strain matrix and the tangent modulus matrix. A scheme of the arrangement of sampling points over the cross‐section that is not consistent with the strain distributions may lead to incorrect predictions of the 3‐D non‐linear elastic–plastic behaviour of beams.This paper investigates the effects of approximations on the 3‐D non‐linear analysis of beams. It is found that a finite element model for 3‐D non‐linear analysis based on the second‐order rotation matrix leads to over‐stiff predictions of the flexural‐torsional buckling and postbuckling response and to an overestimate of the maximum load‐carrying capacities of beams in some cases. To perform a correct 3‐D non‐linear analysis of beams, an accurate model of the rotations must be used. A scheme of the arrangement of sampling points over the cross‐section that is consistent with both the longitudinal normal and shear strain distributions is needed to predict the correct 3‐D non‐linear elastic–plastic behaviour of beams.

A novel three‐dimensional contact finite element based on smooth pressure interpolations
Authors: Jones Reese E. , Papadopoulos Panayiotis 
Published: November 2023

AbstractThis article proposes a new three‐dimensional contact finite element which employs continuous and weakly coupled pressure interpolations on each of the interacting boundaries. The resulting formulation circumvents the geometric bias of one‐pass methods, as well as the surface locking of traditional two‐pass node‐on‐surface methods. A Lagrange multiplier implementation of the proposed element is validated for frictionless quasi‐static contact by a series of numerical simulations. Published in 2001 by John Wiley & Sons, Ltd.
Complementarity methods for multibody friction contact problems in finite deformations
Authors: Chabrand Patrick , Chertier Olivier , Dubois Frédéric 
Published: November 2023

AbstractThis paper deals with the frictional contact occurring between deformable elastoplastic bodies subjected to large displacements and finite deformations. Starting from a standard slave/master formulation we have developed a symmetrical formulation with which the unilateral contact conditions and the friction law are satisfied for each body. From the continuum equations, the discretized frictional contact problem is set as a complementarity problem and solved using Lemke's mathematical programming method. The efficiency of the method is illustrated in the case of several examples. Copyright © 2001 John Wiley & Sons, Ltd.
A numerical estimation of the effects of a cylindrical hole and imperfect bonding on stability of a fibre in an elastic matrix
Authors: Lapusta Yuri N. , Wagner Werner 
Published: November 2023

AbstractA simple numerical model based on three‐dimensional analytical considerations is proposed for an estimation of the local effects of a cylindrical hole in the matrix as well as of fibre–matrix interface imperfections on compressive stability of fibres in fibre‐reinforced composites. The geometry of the model includes an inclusion (a fibre) in a matrix with the assumption of an imperfect bonding at the interface and a cylindrical hole in the closest neighbourhood. Then the problem formulation is idealized in two directions, providing a possibility of establishing lower and upper bounds for critical loads for the case of a matrix with a cylindrical hole of a non‐circular cross‐section as well as for the case of interface imperfections with the possibility of sliding without discontinuity of the displacements normal to the interface. The model takes into account the distinct difference in the properties of the fibre and the matrix and the spatial character of the problem at the microlevel. It is based on individual consideration of the fibre and the matrix with a hole with the necessity of satisfying certain idealized bonding conditions between them.

Published: November 2023

AbstractA new material damping model which is convenient for use in the time‐domain boundary element method (TDBEM) is presented and implemented in a proposed procedure. Since only fundamental solutions for linear elastic material are employed, the procedure has high efficiency and is easy to be integrated into current TDBEM codes. Analytical and numerical results for benchmark problems demonstrate that the accuracy of the proposed method is high. Copyright © 2001 John Wiley & Sons, Ltd.
Eigenderivative analysis of asymmetric non‐conservative systems
Authors: Adhikari Sondipon , Friswell Michael I. 
Published: November 2023

AbstractIn general, the damping matrix of a dynamic system or structure is such that it can not be simultaneously diagonalized with the mass and stiffness matrices by any linear transformation. For this reason the eigenvalues and eigenvectors and consequently their derivatives become complex. Expressions for the first‐ and second‐order derivatives of the eigenvalues and eigenvectors of these linear, non‐conservative systems are given. Traditional restrictions of symmetry and positive definiteness have not been imposed on the mass, damping and stiffness matrices. The results are derived in terms of the eigenvalues and left and right eigenvectors of the second‐order system so that the undesirable use of the first‐order representation of the equations of motion can be avoided. The usefulness of the derived expressions is demonstrated by considering a non‐proportionally damped two degree‐of‐freedom symmetric system, and a damped rigid rotor on flexible supports.

CFD shape optimization using an incomplete‐gradient adjoint formulation
Authors: Soto O. , Löhner R. 
Published: November 2023

AbstractA design methodology based on the adjoint approach for flow problems governed by the incompressible Euler equations is presented. The main feature of the algorithm is that it avoids solving the adjoint equations, which saves an important amount of CPU time. Furthermore, the methodology is general in the sense it does not depend on the geometry representation. All the grid points on the surface to be optimized can be chosen as design parameters. In addition, the methodology can be applied to any type of mesh. The partial derivatives of the flow equations with respect to the design parameters are computed by finite differences. In this way, this computation is independent of the numerical scheme employed to obtain the flow solution. Once the design parameters have been updated, the new solid surface is obtained with a pseudo‐shell approach in such a way that local singularities, which can degrade or inhibit the convergence to the optimal solution, are avoided. Some 2D and 3D numerical examples are shown to demonstrate the proposed methodology. Copyright © 2001 John Wiley & Sons, Ltd.
A geometrical‐based contact algorithm using a barrier method
Authors: Kloosterman G. , van Damme R. M. J. , van den Boogaard A. H. , Huétink J. 
Published: November 2023

AbstractMost methods employed in the numerical solution of contact problems in finite element simulations rely on equality‐based optimization methods. Typically, a gap function which is non‐differentiable at the point of contact is used in these kind of approaches. The gap function can be seen as the Macaulay bracket of some distance function, where the latter is differentiable at the point of contact. In this article, we propose to use the distance function directly instead of using the gap function. This will give rise to a formulation involving inequality constraints. This approach eliminates the artificially introduced non‐differentiability. To this end we propose a barrier algorithm as the method of choice to solve the problem. The method originates in optimization literature, where convergence proofs for the method are available. Copyright © 2001 John Wiley & Sons, Ltd.

AbstractBackgroundEnhancer of zeste homolog 2 (EZH2) catalyzes the trimethylation of histone H3 at lysine 27 via the polycomb recessive complex 2 (PRC2) and plays a time‐specific role in normal fetal liver development. EZH2 is overexpressed in hepatoblastoma (HB), an embryonal tumor. EZH2 can also promote tumorigenesis via a noncanonical, PRC2‐independent mechanism via proto‐oncogenic, direct protein interaction, including β‐catenin. We hypothesize that the pathological activation of EZH2 contributes to HB propagation in a PRC2‐independent manner.Methods and resultsWe demonstrate that EZH2 promotes proliferation in HB tumor‐derived cell lines through interaction with β‐catenin. Although aberrant EZH2 expression occurs, we determine that both canonical and noncanonical EZH2 signaling occurs based on specific gene‐expression patterns and interaction with SUZ12, a PRC2 component, and β‐catenin. Silencing and inhibition of EZH2 reduce primary HB cell proliferation.ConclusionsEZH2 overexpression promotes HB cell proliferation, with both canonical and noncanonical function detected. However, because EZH2 directly interacts with β‐catenin in human tumors and EZH2 overexpression is not equal to SUZ12, it seems that a noncanonical mechanism is contributing to HB pathogenesis. Further mechanistic studies are necessary to elucidate potential pathogenic downstream mechanisms and translational potential of EZH2 inhibitors for the treatment of HB.

AbstractThis work reports the engineering of the magnetic properties of composites based on acrylonitrile butadiene styrene (ABS) by the inclusion of different magnetic nanoparticles (MNP). ABS‐based composites with different MNP, including permalloy, Fe3O4, CoFe2O4, Ni, and Co‐carbon coated, with a 10 wt% content have been prepared and their morphological, electric, thermal, magnetic, and mechanical properties evaluated. Films were processed by solvent casting under two different processing conditions, no magnetic field applied during solvent evaporations, and an out‐of‐plane magnetic field application. It is shown that ABS‐based composites preserve the magnetic properties of the filler, providing a simple way to tune the magnetic behavior in the polymer. The inclusion of permalloy, Fe3O4, CoFe2O4, Ni, and Co‐carbon coated fillers, allow to obtain saturation magnetizations of 6.2, 4.1, 7.3, 3.7, 4.4, and 4.9 emu/g, respectively, and coercive fields of 88.5, 30.9, 128, 2529.8, 123.6, and 197.4 Oe, respectively. It was found that the mechanical properties of the composites depend on filler type and dimensions, maintaining the thermoplastic behavior of the matrix when the fillers are small (up to 40 nm) and losing it when the fillers are bigger (from 60 to 135 nm). Further, the breaking stress, elongation at break, and the Young's modulus are material dependent, showing higher values when the fillers are Fe3O4 and CoFe2O4 and lower values when the fillers are permalloy, Ni, and Co‐carbon; for example, these values are the highest in the case of the ABS‐Fe3O4 composite with values of 28.7 MPa, 4.1%, and 1266.9 MPa, respectively, while ABS‐Co composite shows the lowest breaking stress and elongation at break with 9.2 MPa and 1.5%, respectively. The ABS‐permalloy composite presents the lowest Young's modulus with 781.5 MPa. Also, the magnetic fillers do not change significantly the thermal, dielectric, and the electrical properties of the composites at this concentration (10 wt%). Overall, the present work demonstrates the feasibility of the modulation of the mechanical and the tuning of the magnetic properties of ABS‐based magnetic nanocomposites by changing the magnetic material and by applying a magnetic field during the processing of the composites, allowing their application in areas including sensors, actuators, and magnetic devices.Highlights
Magnetic nanoparticles can engineer the magnetic properties in a composite.
Nanoparticles (NP) can engineer mechanical properties depending on their material.
NP can engineer mechanical properties depending on their dimensions.
With this process, the thermal, electric, and dielectric properties are preserved.
Applied magnetic fields during solvent evaporations affects the Young's modulus.

AbstractWe present a study on a new class of Schiff bases with pyrimidine linked hydrazinyl azole backbone. These compounds were synthesized using conventional and ultrasonication methods. Our design strategy incorporated three heteroaromatic azoles and various substituents on the pyrimidine scaffold to enhance antimicrobial properties. Antibacterial and antifungal screenings were conducted against specific pathogens, and molecular docking studies supported the results. The compounds exhibited significant antimicrobial activities, particularly against K. pneumoniae, surpassing the standard drug. These Schiff bases hold promise as potential antimicrobial agents.
