Textile reinforced concrete is a novel and high performance material which is gaining popularity in the recent days due to its high potential to effectively improve the strength and durability of concrete structures. Owing to absence of coarse aggregate and presence of high cement paste content, TRC has properties that are different from conventional concrete. In this paper, performance of three different types of binders ie., Organic binder, Inorganic Geopolymer binder and epoxy binders for compressive and split tensile strengths was presented and were compared to assess their effectiveness in enhancing properties by testing 12 mortar cubes of size 70.6 mm and 6 mortar cylinders of size 75 × 150 mm. The efficaciousness of weft insertion warp-knitted textile fabrics of ARG and Basalt on the Compressive strength, flexural strength, ductility, toughness, and failure modes were evaluated experimentally by investigations carried out on 4 RCC beams. The effect of the thickness of Textile reinforcement is also studied by using textile layers of thicknesses of 5, 10, and 15 mm. The results indicated that application of basalt textiles fabric using cementitious binder exhibit higher strength and ductility. Basalt textile is more preferable due to its eco-friendly properties. The experimental findings are validated through analytical equations, ensuring the reliability of the study.

The article analyzes the effects of slimming body wraps and massage treatments on skin affected by cellulite. The study evaluated how the complex of slimming wrapping and anti-cellulite massage affects the signs of cellulite, such as changes in the relief of the skin, a decrease in skin temperature, tone, elasticity, and skin hydration. The mentioned evaluation criteria are described in the observation-testing protocol before the first procedure, after 4 procedures and a course of 8 procedures. The charts show the most significant changes based on the procedures performed.

Delayed foreign body reactions to either or both clipping and coating materials have been reported in several small series; however, studies in the titanium clip era are scarce. This study aims to survey the contemporary status of such reactions to titanium clips and coating materials. Among patients who received a total of 2327 unruptured cerebral aneurysmal surgeries, 12 developed delayed intraparenchymal reactions during outpatient magnetic resonance imaging (MRI) follow-up. A retrospective investigation was conducted. The patients' average age was 58.6 (45-73) years, and 11 were women. The aneurysms were located in the middle cerebral artery (n = 7), internal carotid artery (n = 4), or anterior communicating artery (AComA, n = 1). In 10 patients, additional coating with tiny cotton fragments was applied to the residual neck after clipping with titanium clips; however, only the clipping with titanium clips was performed in the remaining two. The median time from surgery to diagnosis was 4.5 (0.3-60) months. Seven (58.3%) patients were asymptomatic, and three developed neurological deficits. MRI findings were characterized by a solid- or rim-enhancing lobulated mass adjacent to the clip with surrounding parenchymal edema. In 11 patients, the lesions reduced in size or disappeared; however, in one patient, an AComA aneurysm was exacerbated, necessitating its removal along with optic nerve decompression. In conclusion, cotton material is a strongly suspected cause of delayed foreign body reactions, and although extremely rare, titanium clips alone may also induce such a reaction. The prognosis is relatively good with steroid therapy; however, caution is required when the aneurysm is close to the optic nerve, as in AComA aneurysms.

This paper sets out the findings of an investigation on the development of a method for calculating aboveground pre-strained cylindrical sheaths, in view of design parameters: the winding angle, pitch and thickness on a concrete base, as a result of which a new expression was obtained. The analysis of the obtained expression showed that the winding thickness variation from 4 mm to 6 mm at the angle of helix of 90º, the value of the strained state parameter (k) varies from 1.3 % to 4.64 %, similar increases in the value of k were obtained with an increase in thickness and at angles of helix of 60º and 75º, where the value of k increased by 0.94–3.82 % and 1.12–4.56 %, respectively. The findings also showed that as the winding thickness increases, the value of k increases independently at different winding angles and pitches. A similar analysis was performed with a variation in the pitch, but with respect to the winding thickness and angle, where the value of k also varies in terms of the winding pitch ranging from 2.61 % to 18.59 % depending on the specific case, and the analysis of the angle of helix showed a variation in the value of k ranging from 0.37 % to 5.24 %. The findings of the variant analysis showed the practicality of the expression obtained, which affords ground for obtaining the required value of the strained state parameter for a particular specific case without carrying out lengthy calculations, which may explicitly supplement the investigations formerly pursued in this course.

Fiber Reinforced Polymer (FRP) composites have been widely used for the repair and strengthening of the reinforced concrete (RC) structures. One of the main problems encountered in these methods is premature debonding failure of externally bonded FRP strip before reaching the strength capacity. In this study, experimental and finite element (FE) studies have been performed to investigate and improve the bonding performance of FRP strips externally bonded to the notched concrete beam surface. Parameters investigated through the experimental studies are (a) bond length, (c) concrete surface quality, (c) BFRP fan anchor, (d) BFRP U wrap anchor, and (e) a new steel anchor type; and that of numerical studies are (a) bond length, (b) concrete surface quality, and (c) a new steel anchor type. Specimens were tested by four-point flexural test under monotonic loading. The change of crack load, ultimate load, deflections, and failure modes were investigated by the results of the experiment and FE analysis. Then, Parametric studies were performed to determine an effective bond length, an efficient thickness of BFRP strips and an effective steel anchor location. According to the findings from the experimental and FE model study, the debonding failure of the non-anchored specimens is caused by the separation of a few millimeter-thick concrete layers from the concrete surface to which the FRP strips are adhered. The results of the experimental study showed that joining the ends of the BFRP strips with steel anchors increased the load-bearing capacity by 24–26% compared to UW and Fan anchors and by 29–43% compared to non-anchored samples; the developed FE model also confirmed these results. In order to effectively utilize the strength capacity of the BFRP strip, anchoring the end of the strip and evenly distributing the load on the BFRP strip proved to be more effective than solely extending the adhesive length.

Wicking in textiles is a key property of fabric moisture permeability, which has been found to be dominant in the comfort-maintaining mechanism of apparel products, especially for sportswear that has high requirements for sweat transfer. Various methods have been given in order to improve moisture transfer behavior of fabrics, among which fiber modification is the most direct and ideal way. In this article, a design-driven yarn structure spinning model for moisture wicking improvement is established by using a helically shaped covering material to limit the inter-fiber spacings of the staple core yarn so that an improvement in effective capillary channels with better continuity can be achieved. The developed yarn constructions combine the advantages of natural and synthetic fibers, showing significant improvements on moisture wicking performance, fast-drying effects as well as commercial values. Experiments on the fabrics made in accordance achieved excellent results both before and after washing. For the most efficient fabric 5 with cotton-linen as the core material, the average diffusion time was decreased by 86.4% and 66.5% before and after washing, compared with the core yarn. Excessively large water absorption rates of the control fabrics were limited and decreased by 22.1% and 32.4%. The evaporation rates of the fabric were increased by 25.6% and 18.5%, indicating obvious improvements in fast drying effects. Through various experiments, the optimal spinning parameters were investigated which provided methods and established foundations for subsequent research. The finding in this study offer the possibility of fiber moisture performance modification with high efficiency, low cost, and environmental sustainability. [ABSTRACT FROM AUTHOR]

Cellular engulfment and uptake of macromolecular assemblies or nanoparticles via endocytosis can be associated to both healthy and disease-related biological processes as well as delivery of drug nanoparticles and potential nanotoxicity of pollutants. Depending on the physical and chemical properties of the system, the adsorbed particles may remain at the membrane surface, become wrapped by the membrane, or translocate across the membrane through an endocytosis-like process. In this paper, we address the question of how the wrapping of colloidal particles by lipid membranes can be controlled by the shape of the particles, the particle–membrane adhesion energy, the membrane phase behavior, and the membrane-bending rigidity. We use a model system composed of soft core–shell microgel particles with spherical and ellipsoidal shapes, together with phospholipid membranes with varying composition. Confocal microscopy data clearly demonstrate how tuning of these basic properties of particles and membranes can be used to direct wrapping and membrane deformation and the organization of the particles at the membrane. The deep-wrapped states are more favorable for ellipsoidal than for spherical microgel particles of similar volume. Theoretical calculations for fixed adhesion strength predict the opposite behavior— wrapping becomes more difficult with increasing aspect ratio. The comparison with the experiments implies that the microgel adhesion strength must increase with increasing particle stretching. Considering the versatility offered by microgels systems to be synthesized with different shapes, functionalizations, and mechanical properties, the present findings further inspire future studies involving nanoparticle–membrane interactions relevant for the design of novel biomaterials and therapeutic applications.

Carbon Fiber Reinforced Polymer (CFRP) considered as unique material as it is proven have the best mechanical properties which can be used as a wrapping. This composite material will be evaluated as a wrapping material using Solid work version 2021 software. Elbow has been chosen as component to be wrapped as it is one of the most critical parts in a pipeline system. Thus, this research focuses on 90-degree butt welded elbows. The study evaluated different lamination and thickness of CFRP as a wrapping framework for elbows. Static analysis also was stimulated to analyze the stress and strain exerted on elbows at extrados location. Based on static analysis simulation from Solid work software, lamination orientation of (0º) with 6 layers exhibit lowest stress for all the pressure tested ranging from 0.86MPa to 19.65MPa for 90-degree defected elbow at extrados location. Besides, comparing CFRP and Glass Fibre Reinforced Polymer (GFRP), CFRP showed it able to reduce stress compared to GFRP when tested on the same defected elbow. Lastly, the flow simulation in CFD showed there were no leakages especially on defected area and no sudden changes on pressure, velocity, and temperature. [ABSTRACT FROM AUTHOR]

Treatment of basilar artery trunk aneurysms is still challenging today, although numerous approaches and modalities of treatment exist. The authors present a case of a patient with a partially thrombosed, ruptured basilar trunk artery aneurysm successfully treated by clipping occlusion of the rupture point and multilayered wrapping of the aneurysmal dome. A 49-year-old man presented to our emergency room with a chief complaint of altered mental status. The patient was diagnosed with subarachnoid hemorrhage (SAH). No apparent bleeding point was identified on initial 3-dimension computerized tomography (CT) angiography and digital subtraction angiography (DSA). Follow-up DSA revealed a partially thrombosed saccular aneurysm emerging from the basilar trunk. We decided to treat the aneurysm surgically with partial clipping including the bleb and wrapping via the anterior transpetrosal approach. The surgery was performed successfully without any complications, and the residual blood flow within the aneurysm diminished remarkably over time. Although direct clipping and wrapping for basilar trunk artery aneurysms is one of the most challenging operations, it is a highly effective treatment for complex aneurysms, especially if other treatments are not available.

Polymers stabilize the nanoparticles onto which they wrap, avoiding coagulation and undesired phase separation processes. Wrapping gives rise to hybrid colloids, and is useful in bio-intended applications. In non-covalent interaction modes, polymers physically adsorb onto the nanoparticles' surface, NPs, and some of their portions protrude outside. Both their non-interacting parts and the free polymers are in contact with the solvent, and/or are dispersed in it. Wrapping/protruding ratios were forecast with a simple statistical thermodynamic model, and the related energy calculated. The wrapping efficiency is controlled by different contributions, which stabilize polymer/NP adducts. The most relevant ones are ascribed to the NP-polymer, polymer–polymer, and polymer–solvent interaction modes; the related energies are quite different from each other. Changes in the degrees of freedom for surface-bound polymer portions control the stability of adducts they form with the NPs. The links between wrapped, free, and protruding states also account for depletion, and control the system's properties when the surface adsorption of hosts is undesired. Calculations based on the proposed approach were applied to PEO wrapping onto SiO2, silica, and nanoparticles. The interaction energy, W, and the changes in osmotic pressure associated with PEO binding onto the NPs have been evaluated according to the proposed model. [ABSTRACT FROM AUTHOR]

In 1985 Hopcroft, Joseph and Whitesides showed it is NP-complete to decide whether a carpenter's ruler with segments of given positive lengths can be folded into an interval of at most a given length, such that the folded hinges alternate between 180 degrees clockwise and 180 degrees counter-clockwise. At the open-problem session of 33rd Canadian Conference on Computational Geometry (CCCG '21), O'Rourke proposed a natural variation of this problem called ruler wrapping, in which all folded hinges must be folded the same way. In this paper we show O'Rourke's variation has a linear-time solution. [ABSTRACT FROM AUTHOR]

Pultruded Glass Fiber-Reinforced Polymer (pultruded GFRP) composite produced by the pultrusion method has become popular in civil engineering applications due to its lightness, corrosion resistance and high strength. However, the use of the pultruded profile combining with reinforced concrete is still limited due to a lack of knowledge. Therefore, the behavior of the pultruded GFRP profile infilled with reinforced concrete beams (hybrid beams) is investigated. This study focused on the effects of stirrup spacing for the hybrid beams. Pursuant to this goal, a total of eight different beams were tested under four-point loading. One reference beam without the pultruded profile and seven hybrid beams having different stirrup spacings were considered. Moreover, the hybrid beams with and without stirrups were wrapped by unidirectional GFRP composite to investigate the effects of stirrup spacing on shear capacity of the beams strengthened by GFRP composite. The experimental findings revealed that tightening stirrups increased the load and energy dissipation capacities of the hybrid beams; however, it could not prevent brittle failure. On the other hand, wrapping hybrid beams with GFRP composite increased the load and energy dissipation capacities and also prevented brittle failure regardless of the presence of the stirrups. Therefore, it is strongly recommended that the unidirectional pultruded profiles should be strengthened with 90° GFRP wrapping to have ductile behavior. [ABSTRACT FROM AUTHOR]

[Display omitted] Polymeric fiber fabrics with inherent mechanical flexibility, lightweight and porous textile structure are highly attractive as an ideal substrate for building flexible electrodes. However, their insulating nature limits their direct application as current collector. Here, we designed and fabricated a flexible conductive fabric from polymer yarns. This was achieved through wrapping polymer yarns with a carbon nanotube (CNT) cylinder, which was continuously prepared from a floating catalyst chemical vapor deposition process, and a subsequent knitting process. The derived CNT-wrapped polymer yarn fabric (CPYF) could directly serve as current collector/substrate to load zeolitic imidazolate framework-67 (ZIF-67) and polypyrrole (PPy) through in-situ growth and chemical polymerization. The resultant CPYF-ZIF-67-PPy displayed a maximum areal capacitance of 2308.8 mF cm−2 at 0.5 mA cm−2. Moreover, the assembled supercapacitor achieved a maximum areal energy density of 112 μW h cm−2 at the power density of 201.5 μW cm−2. Meanwhile, the device demonstrated an extraordinary flexibility with stable electrochemical properties after 5000 cycles of bending and 1000 cycles of stretching. This work therefore offers a new strategy that can be used to develop flexible conductive fabric for flexible supercapacitors. [ABSTRACT FROM AUTHOR]

Expanded polystyrene (EPS) concrete is a low-carbon green building material, which has the properties of thermal insulation, but its strength is not high at present. To improve the strength of EPS concrete, EPS particles were wrapped on the surface by magnesium phosphate cement, ultra-high performance concrete, and waterborne polyurethane, they were used to make concrete after aging, and then the strength and microproperties of concrete were tested. The test results show that the wrapping material form a shell structure on the surface of EPS particles; the hydrophilic property of the wrapped EPS particles and the uniformity of the concrete have been significantly improved; the contact between the wrapped EPS particles and the cement base has become more closer; the cube compressive strength of concrete is increased by 80–110%, the flexural strength of concrete is increased by 40–90%. The research results of this study are of great significance for EPS concrete used as structural material and fabricated lightweight wallboard.

In phase-contrast magnetic resonance imaging (PC-MRI), spin velocity contributes to the phase measured at each voxel. Therefore, estimating velocity from potentially wrapped phase measurements is the task of solving a system of noisy congruence equations. We propose Phase Recovery from Multiple Wrapped Measurements (PRoM) as a fast, approximate maximum likelihood estimator of velocity from multi-coil data with possible amplitude attenuation due to dephasing. The estimator can recover the fullest possible extent of unambiguous velocities, which can greatly exceed twice the highest venc. The estimator uses all pairwise phase differences and the inherent correlations among them to minimize the estimation error. Correlations are directly estimated from multi-coil data without requiring knowledge of coil sensitivity maps, dephasing factors, or the actual per-voxel signal-to-noise ratio. Derivation of the estimator yields explicit probabilities of unwrapping errors and the probability distribution for the velocity estimate; this, in turn, allows for optimized design of the phase-encoded acquisition. These probabilities are also incorporated into spatial post-processing to further mitigate wrapping errors. Simulation, phantom, and in vivo results for three-point PC-MRI acquisitions validate the benefits of reduced estimation error, increased recovered velocity range, optimized acquisition, and fast computation. A phantom study at 1.5T demonstrates 48.5% decrease in root mean squared error using PRoM with post-processing versus a conventional “dual-venc” technique. Simulation and 3T in vivo results likewise demonstrate the proposed benefits. [ABSTRACT FROM AUTHOR]

The rubber band gripper is an automatic contraction ring that is used to wrap and fix objects of various shapes by vacuuming the inside of the ring. It can be used to handle objects as a robot gripper, as well as fix bodies to pedestals, and objects to bodies. This study geometrically analyzes object shapes that can be wrapped using the ring, without causing gaps in the gripping mechanism. The analysis and experimental results show that the object shapes that can be wrapped without gaps are determined by the maximum shrinkage rate after the ring contacts the object as well as the circumference of the object. The range of object shapes that can be wrapped without gaps narrows as the object position moves away from the center of the ring. However, this influence is small, except when the object is small or has a large aspect ratio. In particular, when the object shape is cylindrical, it can be wrapped without gaps regardless of its position within the ring. [ABSTRACT FROM AUTHOR]

The Euler-Eytelwein equation indicates that the tension from one end of the rope to the other end decays exponentially with the wrapping angle after wrapping around a target object, and the tensions at two ends can differ by several orders of magnitude. The ability to scale the force magnitude of this wrapping structure may be exploited for space captures. This paper simplifies the modeling of the actual scene of space capture, analyzes the kinematic characteristics of the wrapping process of tethered projectile systems, and obtains the trajectory equation of the projectile. Carrying out the force analysis of the element, forces acting on the satellite and the target object under different friction coefficients are obtained. Finally, considering two constraints of rope tension and wrapping time, as well as the number of wrapping turns for safe, a design scheme of projectile velocity and initial rope length required for successful capture is proposed.

Click-through rate (CTR) prediction, whose goal is to predict the probability of the user to click on an item, has become increasingly significant in the recommender systems. Recently, some deep learning models with the ability to automatically extract the user interest from his/her behaviors have achieved great success. In these work, the attention mechanism is used to select the user interested items in historical behaviors, improving the performance of the CTR predictor. Normally, these attentive modules can be jointly trained with the base predictor by using gradient descents. In this paper, we regard user interest modeling as a feature selection problem, which we call user interest selection. For such a problem, we propose a novel approach under the framework of the wrapper method, which is named Meta-Wrapper. More specifically, we use a differentiable module as our wrapping operator and then recast its learning problem as a continuous bilevel optimization. Moreover, we use a meta-learning algorithm to solve the optimization and theoretically prove its convergence. Meanwhile, we also provide theoretical analysis to show that our proposed method 1) efficiencies the wrapper-based feature selection, and 2) achieves better resistance to overfitting. Finally, extensive experiments on three public datasets manifest the superiority of our method in boosting the performance of CTR prediction. [ABSTRACT FROM AUTHOR]

A principal part of the Comprehensive Research Facility for Fusion Technology (CRAFT) is the toroidal field (TF) coil project, which aims at fabricating a prototype TF coil for China Fusion Engineering Test Reactor (CFETR). The TF coil is composed of 3-D-shaped subwinding packs (sub-WPs) enclosed in a stainless coil case, and the conductor core of medium and high field sub-WPs is Nb3Sn, following the “Winding & Reaction” manufacturing process. After heat treatment of the conductor, turn insulation will be automatically wrapped. Strictly restricted by the brittleness of the heat-treated Nb3Sn, the strain must be controlled during the wrapping process. Presented in this article is a description of the CRAFT TF coil and its turn insulation structure, followed by descriptions of the structural design of the wrapping unit and mathematical models about wrapping control of the wrapping machine. Turn insulation wrapping trials are performed with one-fourth part of the wrapping unit, and tapes with a fixed width and a uniform steel tube are used as specimens, verifying the correctness of the structure and models. The one-fourth part of the wrapping unit has been fabricated in March 2022 and it is foreseen that the fabrication will be finished in June 2022. [ABSTRACT FROM AUTHOR]

The ricotta cheese undergoes early microbiological spoilage and high moisture loss that leads to brittle texture. The development of edible films based on active biomaterials plays an important role in the cheese industry. Thus, gelatin was extracted from the grey triggerfish (Balistes capriscus) co-product. The gelatin films were prepared and enriched with 5, 10 and 20 µg/ml of different solvent extracts from Moringa oleifera leaves. As compared to the control film, the lightness (L*) and redness (a*) of the enriched films decreased slightly, while their yellowness (b*) increased as the level of enrichment increased. No significant difference (p > 0.05) was measured in the thickness, tensile strength and elongation at break of the enriched films. As compared to the control geltin-based film, the film enriched with 20 µg/ml of ethanolic extract (F-MOE) showed 35% reduction in water vapor permeability, and then was chosen to wrapp cheese. Interestingly, after 6 days of storage, the F-MOE-wrapped ricotta cheese showed a significant reduction (p ≤ 0.05) in weight loss, approximately 34% compared to the unwrapped cheese. Furthermore, the F-MOE-wrapped cheese showed the lowest changes in pH, color and texture parameters, as well as the lowest levels of lipid peroxidation (0.90 ± 0.03 mg MDA/kg cheese), and yeasts and molds (2.78 ± 0.14 log CFU/g cheese), which could be explained by the phenolics incorporated into the film. The film made from grey triggerfish gelatin and enriched with M. oleifera ethanolic extract could be used to reduce microbiological spoilage and preserved the physical quality of ricotta cheese, which were economically important parameters.

In the three-dimensional video system, the depth image-based rendering is a key technique for generating synthesized views, which provides audiences with depth perception and interactivity. However, the inaccuracy of depth information leads to geometrical rendering position errors, and the compression distortion of texture and depth videos degrades the quality of the synthesized views. Although existing quality enhancement methods can eliminate the distortions in the synthesized views, their huge computational complexity hinders their applications in real-time multimedia systems. To this end, a residual distillation enhanced network (RDEN)-guided lightweight synthesized view quality enhancement (SVQE) method is proposed to minimize holes and compression distortions in the synthesized views while reducing the model complexity. First, a rethinking on the deep-learning-based SVQE methods is performed. Then, a feature distillation attention block is proposed to effectively reduce the distortions in the synthesized views and make the model fulfill more real-time tasks, which is a lightweight and flexible feature extraction block using an information distillation mechanism and a lightweight multi-scale spatial attention mechanism. Third, a residual feature fusion block is proposed to improve the enhancement performance by using the feature fusion mechanism, which efficiently improves the feature extraction capability without introducing any additional parameters. Experimental results prove that the proposed RDEN efficiently improves the SVQE performance while consuming few computational complexities compared with the state-of-the-art SVQE methods.

Label-specific features serve as an effective strategy to learn from multi-label data, where a set of features encoding specific characteristics of each label are generated to help induce multi-label classification model. Existing approaches work by taking the two-stage strategy, where the procedure of label-specific feature generation is independent of the follow-up procedure of classification model induction. Intuitively, the performance of resulting classification model may be suboptimal due to the decoupling nature of the two-stage strategy. In this paper, a wrapped learning approach is proposed which aims to jointly perform label-specific feature generation and classification model induction. Specifically, one (kernelized) linear model is learned for each label where label-specific features are simultaneously generated within an embedded feature space via empirical loss minimization and pairwise label correlation regularization. Comparative studies over a total of sixteen benchmark data sets clearly validate the effectiveness of the wrapped strategy in exploiting label-specific features for multi-label classification.

Due to its ultrafast cross-luminescence, the BaF2 crystals with a subnanosecond decay time are promising for high-reputation radiation detection. However, there is a slow scintillation component with a decay time of about 600 ns in the crystal, which induces a pile-up effect. The Y doping in the crystal was confirmed to be effective in slow component suppression. In this investigation, the fast/total (F/T) light yield (LY) ratios and fast component LY of BaF2:Y crystals with various Y concentrations were investigated by the fast sampling technique. It was demonstrated that Y doping not only suppresses the slow component but also weakens the fast component. A good negative correlation was observed between the F/T LY ratios and fast component LY of BaF2:Y crystals, indicating that it was impossible to obtain the BaF2:Y crystal with a high F/T LY ratio and a high fast component LY at the same time. The influence of wrapping materials on the F/T LY ratio was also investigated. The result illustrates that both the undoped and Y-doped BaF2 crystals without wrapping materials show the best F/T LY ratio, indicating that the tradeoff between LY and F/T LY ratio is needed in the applications.

The use of fiber-reinforced polymer (FRP) composites in compressive members is advantageous to reinforced concrete structures in order to alleviate the problem of corrosion of steel reinforcement and to produce a lightweight and efficient structural element. This investigation aims to propose the theoretical models for capturing the axial loading capacity (ALC) of hollow concrete columns (HCCs) having main FRP rebars and transverse FRP spirals. All the glass-FRP-reinforced HCCs portray two-peak load performance. The first peak is due to the gross cross-sectional area of concrete while the second peak is due to the core material laterally wrapped with FRP spirals. For the prediction of the first peak load of HCCs which is equal to the maximum capacity of solid concrete columns, a database of 279 FRP-reinforced columns was produced from the previous research and the ALC models were suggested; one for capturing the first peak and the other for estimating the second peak ALC of HCCs. The predictions of proposed models were compared with the test results from the literature. A close relationship was perceived between the theoretical and experimental results.

Given an input 3D geometry such as a triangle soup or a point set, we address the problem of generating a watertight and orientable surface triangle mesh that strictly encloses the input. The output mesh is obtained by greedily refining and carving a 3D Delaunay triangulation on an offset surface of the input, while carving with empty balls of radius alpha. The proposed algorithm is controlled via two user-defined parameters: alpha and offset. Alpha controls the size of cavities or holes that cannot be traversed during carving, while offset controls the distance between the vertices of the output mesh and the input. Our algorithm is guaranteed to terminate and to yield a valid and strictly enclosing mesh, even for defect-laden inputs. Genericity is achieved using an abstract interface probing the input, enabling any geometry to be used, provided a few basic geometric queries can be answered. We benchmark the algorithm on large public datasets such as Thingi10k, and compare it to state-of-the-art approaches in terms of robustness, approximation, output complexity, speed, and peak memory consumption. Our implementation is available through the CGAL library. [ABSTRACT FROM AUTHOR]

Range-Doppler detection with pulse sequences exists widely in Radar, sonar, ultrasound imaging, and many other engineering applications. However, the classic methods require a high sampling rate for wideband pulses, and the Doppler estimation with slow time sub-Nyquist sampling may suffer from the phase wrapping. In this brief, a sequential-based range-Doppler estimation method with fast and slow time sub-Nyquist sampling is proposed. Utilizing the finite rate of innovation (FRI) theory, the range parameters can be estimated from several Fourier coefficients. The fast time sampling rate is determined by the number of the unknown parameters, instead of the signal bandwidth. Then, the aliasing-free Doppler parameters are estimated by the subspace method and the Chinese remainder theorem (CRT). The sequential-based method enables to estimate each Doppler parameter separately, and the Doppler estimation is transformed into a robust CRT problem, which enhances the robustness of the Doppler estimation. Simulation and hardware results demonstrate the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

ObjectivesThis study aims to identify the effectiveness of the clip-reinforced wrapping using the Y-shaped temporalis fascia (CRYST) technique for treating intracranial aneurysms (IAs).MethodsWe retrospectively reviewed five patients with ruptured IAs treated using the CRYST technique from July 2016 to May 2021. Three patients had blood blister-like aneurysms (BBAs) (one with intraoperative rupture), and two had anterior communicating artery (AcoA) aneurysms (one with intraoperative rupture). All patients had intraoperative indocyanine green angiography, and digital subtraction angiography (DSA) was reviewed 10–14 days after surgery. At 1 year postoperatively, three patients (two BBAs and one AcoA aneurysm) underwent DSA and two patients (one BBA and one AcoA aneurysm) underwent computed tomographic angiography (CTA).ResultsTwo aneurysms ruptured intraoperatively during the clipping, and no severe complications occurred. No patients had neurological deficits after surgery, and they had good outcomes. Four DSAs showed no aneurysms and no significant stenosis of the parent artery 10–14 days after surgery. One patient had mild stenosis of the parent artery on DSA 10 days after surgery; the stenosis improved on DSA 1 year after surgery. No other aneurysms recurred, and parent arteries were clear on CTA or DSA 1 year after surgery.ConclusionsCombining our accumulated experience in the work and literature, we described the CRYST technique to treat intractable IAs with specific morphologies and irregular wall structures in our patients. All outcomes and follow-up results were favorable.

Abstract Water companies and their consumers affected with leakages in water distribution system worldwide. This has attracted many practitioner’s attention as well as researchers over the past years. Selected study area suffers from water losses of about 10 to 15% which accounts to loss of about 9 to 9.75 million liters per month. The present study was under taken to understand, analyze and evaluate the losses and suggest preventive measures of wrapping and repair clamping for control of these losses. The assessment of water losses is done through comparative analysis of data using Microsoft Excel software. Population forecasting is done in context of assessing the amount of water lost that can be prevented in future decades, adjusting to increased water demand and losses. For better efficiency of the suggested methods, experimental analysis was carried out on a reduced scale model of a single stretched pipeline. Cost estimation of the preventive measures was done by obtaining information about the materials used by trading professionals.

AIM: To retrospectively compare postoperative outcomes after primary enucleation and placement of a hydroxyapatite (HA) implant without wrapping, wrapped with auricular cartilage or donor sclera. METHODS: Medical records of patients presented as intraocular tumor or severe ocular injury were identified from the electronic medical record system. Cases underwent enucleation and HA orbital implantation were enrolled in this study and were divided into 3 groups according to the wrapping material of HA implant. Cases with autogenous cartilage caps were enrolled in group A (n=11), with donor sclera caps in group B (n=12), and without any wrapping material in group C (n=9). Follow-ups were set at 1, 2wk, 1, 3, 6, and 12mo after surgery. RESULTS: Altogether 32 cases finished the follow-up and were enrolled in this study. Three cases (27.27%) in group A, 4 cases (33.33%) in group B, and 4 cases (44.44%) in group C developed one complication each after surgery. In group A, no HA exposure occurred, but conjunctival inclusion cyst occurred in one and severe conjunctive chemosis in two cases. In group B, one HA exposure occurred, conjunctive inclusion cysts occurred in one, severe conjunctive chemosis occurred in one, and conjunctival granuloma occurred in one case. In group C, one HA exposure occurred, severe conjunctive chemosis occurred in two cases, and conjunctival granuloma occurred in one case. The case of exposure of none-wrapped implant was noted in the first 6mo after placement of the orbital implant. The case of exposure of donor sclera-wrapped implant was noted at the 12mo after placement of the orbital implant. Both exposure cases were treated successfully with conservative treatment. CONCLUSION: With low incidence of implant exposure and mild complications, auricular cartilage can be a good choice of alternative wrapping material of orbit implant with satisfied outcome.

In this paper, we report on a study of visual representations for cyclical data and the effect of interactively wrapping a bar chart ‘around its boundaries’. Compared to linear bar chart, polar (or radial) visualisations have the advantage that cyclical data can be presented continuously without mentally bridging the visual ‘cut’ across the left-and-right boundaries. To investigate this hypothesis and to assess the effect the cut has on analysis performance, this paper presents results from a crowdsourced, controlled experiment with 72 participants comparing new continuous panning technique to linear bar charts (interactive wrapping). Our results show that bar charts with interactive wrapping lead to less errors compared to standard bar charts or polar charts. Inspired by these results, we generalise the concept of interactive wrapping to other visualisations for cyclical or relational data. We describe a design space based on the concept of one-dimensional wrapping and two-dimensional wrapping, linked to two common 3D topologies; cylinder and torus that can be used to metaphorically explain one- and two-dimensional wrapping. This design space suggests that interactive wrapping is widely applicable to many different data types. [ABSTRACT FROM AUTHOR]

Sunflower seeds are a source of vegetable protein, in 100 g seeds contain 20.78 g protein, total lipid 51.46 g, ash content 3.02 g, carbohydrate 20.0 g and 8.6 g fiber with a total energy of 2445kj. Sunflower seeds are also a source of choline (55.1 mg) and ethanolamine (35.4 mg). Judging from the nutritional value, sunflower seeds are very potential to be developed into various processed products, including tempeh. Utilization of sunflower seeds for making tempeh can produce a new food product that is rich in protein other than soybeans so that it can reduce dependence on soybean commodities. Sunflower seeds are also rich in Vitamin E which functions as a natural antioxidant for the body. The purpose of this study was to determine the effect of differences in packaging material and fermentation time on the characteristics of the tempe produced. This study used a two-factor Complete Randomized Design, namely the type of wrapper (banana leaf, teak leaf, plastic with a hole spacing of 2cm, plastic with a hole spacing of 1cm) and a factor of 2 fermentation periods (36 and 48 hours). The data obtained were analyzed using Variance Analysis (ANOVA). If there were significant differences between treatments, further tests were carried out with DMRT (Duncan) with a level of 5%. The results showed that the best treatment was the type of teak leaf wrapping and 36 hours fermentation time, which produced tempeh with the highest consumer preference value, namely texture 3.24; taste of 4.0; 3.56 color and 3.44 aroma. Characteristics of tempeh in the treatment were a total mold of 8.66 log fcu / g; total microbes 9.41 log cfu / g; vitamin E levels 24.25 mg / 100g; dissolved protein 11.93%.
