In this paper, we study a class of conformal metric deformations in the quasi-radial coordinate parametrizing the three-sphere in the conformally compactified Minkowski spacetime S 1 × S 3 . Prior to reduction of the associated Laplace–Beltrami operators to a Schrödinger form, a corresponding class of exactly solvable potentials (each one containing a scalar and a gradient term) is found. In particular, the scalar piece of these potentials can be exactly or quasi-exactly solvable, and among them we find the finite range confining trigonometric potentials of Pöschl–Teller, Scarf and Rosen–Morse. As an application of the results developed in the paper, the large compactification radius limit of the interaction described by some of these potentials is studied, and this regime is shown to be relevant to a quantum mechanical quark deconfinement mechanism.

In this study, printing designs inspired by the motifs of the Saudi heritage have been developed based on the experimental and descriptive approaches. The investigation aims to study and analyses some of the elements and decorative units of the heritage found in the western region of the Kingdom of Saudi Arabia and to benefit from them in the development of decorative designs that have the aesthetic aspect and are compatible with the function of accessories and offering Saudi cultural heritage in a contemporary spirit, while enriching the aesthetic and functional aspects of innovative decorative designs. Heritage decorations for the western region of Saudi Arabia have been studied for the design of various costume supplements (scarves-belts-bags), and it has been concluded that all designs benefit from the aesthetic values of heritage decorations at a very high level and that all designs achieve the aesthetic and functional aspects at a very high level. One of the most important recommendations of the study is communication between local designers and manufacturers in Saudi Arabia to contribute to the promotion of creative industries and support for the local economy.

We show that an estimate by de la Peña, Ibragimov, and Jordan for ${\mathbb{E}}(X-c)^+$ , with c a constant and X a random variable of which the mean, the variance, and $\mathbb{P}(X \leqslant c)$ are known, implies an estimate by Scarf on the infimum of ${\mathbb{E}}(X \wedge c)$ over the set of positive random variables X with fixed mean and variance. This also shows, as a consequence, that the former estimate implies an estimate by Lo on European option prices. [ABSTRACT FROM AUTHOR]

A prediction method based on the stepped-lap repair strength was proposed to study the parameterization of repairing the damaged wind turbine blade spar cap structure. First, the numerical analysis model of spar cap damage was established based on the continuous damage mechanics model, the puck criterion, and the cohesive zone model. Then, the influence of the repair parameters on the repair strength was studied based on the stepped-lap repair theory. Finally, the optimal repair scheme was determined by a strength recovery rate analysis. Results demonstrate that increasing lap length and the number of overply layers can enhance the load-carrying capacity of the stepped-lap repair structure within a certain range. Lap length and the number of overply layers substantially affect the bearing capacity of the spar cap. The influence of the overply layer is slightly higher than that of the lap length, while the lap width effect remains relatively minor. [ABSTRACT FROM AUTHOR]

We consider the generalization of the classical Shapley and Scarf housing market model (Shapley and Scarf, 1974) to so-called multiple-type housing markets (Moulin, 1995). Throughout the paper, we focus on strict preferences. When preferences are separable, the prominent solution for these markets is the typewise top-trading-cycles (tTTC) mechanism. We first show that for lexicographic preferences, a mechanism is unanimous (or onto), individually rational , strategy-proof , and non-bossy if and only if it is the tTTC mechanism. Second, we obtain a corresponding characterization for separable preferences. We obtain additional characterizations when replacing [ strategy-proofness and non-bossiness ] with self-enforcing group (or pairwise) strategy-proofness. Finally, we show that for strict preferences, there is no mechanism satisfying unanimity , individual rationality , and strategy-proofness. Our characterizations of the tTTC mechanism constitute the first characterizations of an extension of the prominent top-trading-cycles (TTC) mechanism to multiple-type housing markets.

This paper extends Scarf's (1971) α -core result to a dynamic Cournot oligopoly. It shows that the α , β , γ -cores are all non-empty in an n -firm dynamic Cournot oligopoly with linear demand and symmetric quadratic costs. • This paper extends Scarf's (1971) α -core result to a dynamic Cournot oligopoly. • The non-emptiness of α , β and γ -cores is proved in an n-firm dynamic Cournot oligopoly. • It demonstrates that the dynamic γ -core is a subset of the core, consistent with the static case.

Experimental and simulation studies of the response of bonded‐repaired and scarf‐repaired carbon fiber‐reinforced polymer laminates under the low‐velocity impact (LVI) were carried out. The center‐ and eccentric‐repaired laminates were prepared for experiments. The experimental results verify the validity of the finite element model in terms of the force response and different modes of damage. The effect of impact energy and the variation of repair position on the impact response of the laminate was investigated based on the benchmark model. The bonded repaired laminates have higher peak impact forces and lower energy absorption than the scarf‐repaired laminates; the damage of the bonded repaired laminate is mainly intralaminar damage and delamination damage of the patch; the adhesive of the scarf repair is prone to failure, leading to poor impact resistance. The relative positions of the impact point and the patch determine the impact response of a laminate repaired at different locations. The impact point at the edge of the patch has a detrimental effect on the repaired laminate. The impact point vertical position near the bottom hole edge of the parent plate in the scarf‐repaired case harms the impact resistance of the laminate. Highlights: The low‐velocity impact response of bonded versus scarf‐repaired laminates was compared.Bonding repairs provide superior impact resistance to damaged laminates than scarf repairs.The risk of adhesive failure in scarf repair is significantly higher than in bonded repair.The relative position of the damage (repair) to the impact point critically influences the impact response.Impacts near the edge of the initial damage hole can cause severe damage to scarf‐repaired laminates.

Within the framework of the enlargement methodological proposed by the thinker Arturo Roig, we expose the need for a Latin American symbolic or semiotic and we unravel Roigean symbol theory, in its double facet: axiology and normativity. Then, we reflect on the distinction between signification and meaning that allows us to open ourselves to the metaphorical system implicit in words as semantic marks. Subsequently, we explain the characteristics of the symbolic universe: conflict, discursive dualism and reversal, in order to show the Roigean interpretation of Caliban as an example of reversal of the symbolic function. Subsequently, we delve into the feminist interpretation of the Sycorax figure as a symbol of resistance and liberation. Finally, we highlight the importance of the scarf as a symbol and the struggle of women in their relentless struggle for their rights. [ABSTRACT FROM AUTHOR]

Fiber-reinforced composite materials are increasingly used in oil and gas transmission, and joints are the areas prone to failure in pipelines. Damage evolution in the adhesive joints connecting pipes made for basalt-fiber-reinforced polymers (BFRPs) was analyzed. First, finite-element models for three types of adhesive joints (single-lap, sleeve, and scarf ones) were developed. Second, an optimal cohesive zone model (CZM) for the adhesive layer was developed based on the inverse analysis of the results of debonding experiments. Finally, the damage evolution in the adhesive joints was analyzed under internal pressure, tension, bending, and torque, and their pipeline loading capacities were evaluated. Results showed that the single-lap joint exhibited the highest ultimate load-carrying capacity at a unit overlapping length, followed by the sleeve joint, but the scarf joint had the lowest unit ultimate load. For sleeve and scarf joints, the presence of a gap or a weak interface between two pipe adherends led to a reduction in their load-carrying capacity. These findings provide a basis for the design of the composite pipe joints. [ABSTRACT FROM AUTHOR]

The transformations of supersymmetric quantum mechanics are discussed within a formalism that employs a six-parameter function, from which the superpotential and the supersymmetric partner potentials V − (x) and V + (x) are constructed in a general form. By specific choice of the parameters, V − (x) and V + (x) are matched with the general form of PI class potentials and their rationally extended versions. The choice of the parameters also determines which of the four possible SUSY transformations T i , i = 1 , ... 4 is in effect. After this general discussion, the formulae are specified to the three members of this potential class, the Scarf I, Scarf II and generalized Pöschl–Teller potentials. Due to the different domains of definition and their consequences on the boundary conditions, the results turn out to be rather diverse for the three potentials, while the mathematical formalism and the network of the potentials interconnected by the SUSYQM transformations still remains common to a large extent. The general framework allows a unified and consistent interpretation of earlier isolated findings. It also helps to connect the results to further potential classes and to place them into a more general context within the zoo of exactly solvable potentials. [ABSTRACT FROM AUTHOR]

Background: Traditional Scarf osteotomy (TSO) is an effective procedure with a good record in moderate to severe hallux valgus (MSHV) surgery. In order to overcome shortcomings of TSO, Modified Rotary Scarf osteotomy (MRSO) was introduced in this study, which aimed to compare the clinical and radiological outcome in the patients treated with MRSO or TSO. Methods: Of 175 patients (247 feet) with MSHV, 100 patients (138 feet) treated with MRSO and 75 patients (109 feet) treated with TSO were evaluated according to relevant indicators in twenty-four months follow-up. Pre-surgical and post-surgical HVA, IMA, DMAA, MTP-1 ROM, sesamoid grade and AOFAS (American Orthopaedic Foot and Ankle Society) scores and postsurgical complications were evaluated. Results: Both groups manifested similar baseline characters. The mean follow-up was of 25.9 (range, 22–37) months. Significantly lower IMA, lower Sesamoid grade and higher DMAA at six months, twelve months and twenty-four months post-surgically had been showed in MRSO group compared to TSO group. There was no significant difference in HVA, MTP-1 ROM and AOFAS data at each follow-up time point post-surgically between the two groups. No major complications occurred in either group. Conclusion: MRSO showed comparable results to TSO, and improved IMA and sesamoid grade to a greater extent, with a lower probability of throughing effect. Although DMAA could be increased by MRSO, MRSO could still be a reproducible, non-dangerous and efficacious alternative procedure for treating HV patients which do not have severe DMAA.

In order to investigate the continuation and innovation of Adelais culture in contemporary fashion and explore the effective application of Adelais silk patterns in scarves, this study meticulously selected 13 representative Adelais silk patterns from Xinjiang and arranged them into scarves with distinct pattern combinations but uniform style and design. A group of female participants aged between 18~50 years were surveyed based on the principles of sensory engineering, and the findings were subsequently analyzed by mean analysis, factor analysis, and grey correlation analysis. The results show that Adelais silk patterns significantly impact the sensory perception of scarves, with temperament constituting the principal factor that influences consumers' preference for scarves, appearance having a relatively minor effect.

In this paper, we extend constructions and results for the Taylor complex to the generalized Taylor complex constructed by Herzog. We construct an explicit DG-algebra structure on the generalized Taylor complex and extend a result of Katthän on quotients of the Taylor complex by DG-ideals. We introduce a generalization of the Scarf complex for families of monomial ideals, and show that this complex is always a subcomplex of the minimal free resolution of the sum of these ideals. We also give an example of an ideal where the generalized Scarf complex strictly contains the standard Scarf complex. Moreover, we introduce the notion of quasitransverse monomial ideals, and prove a list of results relating to Golodness, Koszul homology, and other homological properties for such ideals.

Objective: Rotational Scarf osteotomy has its unique advantages in treating hallux valgus, but it also has certain drawbacks. The biomechanical differences between rotational Scarf and translational Scarf osteotomy are not clear evaluates the correction ability and biomechanical difference of two surgical methods for hallux valgus by finite element analysis. Methods: The computerized tomography data of a hallux valgus patient were selected to establish a finite element model. The standard Scarf osteotomy was simulated based on the model, and the rotation and translation were performed, respectively. The size of the intermetatarsal angle, contact area, distal metatarsal articular angle and the absolute length of the first metatarsal was compared between the two groups. We completed the cartilage, ligament and other tissues on the bone model to establish a full foot model. We analyzed the troughing, plantar aponeurosis tension, plantar soft tissue, and ground stress and also observed the stability of the fracture site by a three‐point bending test. Results: Both surgical methods may effectively correct the intermetatarsal angle. After rotational osteotomy, the contact area increased, and the length of the first metatarsal bone initially increased and then decreased compared to that in the translational group. Furthermore, rotational Scarf significantly increased the distal metatarsal articular angle. Mechanical analysis showed that the cancellous bone in the contact part of the fracture site in the translation group had greater stress, which was the reason for the occurrence of the troughing. Stress distribution of plantar aponeurosis, plantar soft tissue, and the ground showed no significant difference. The three‐point bending test showed that the separation of the broken ends of the rotational Scarf osteotomy model (0.133 mm) was slightly smaller than the translational group (0.147 mm). Conclusion: Both surgical methods can successfully correct intermetatarsal angle (IMA). Compared to traditional translational Scarf osteotomy, rotational Scarf osteotomy is more conducive to postoperative stability and healing, but it also has certain drawbacks. In clinical practice, individualized surgical methods still need to be selected for different types of patients with hallux valgus. [ABSTRACT FROM AUTHOR]

This article presents strategies for conserving and storing historical textiles that have deteriorated from exposure to uncontrolled environmental conditions. The focus of this study was to document the treatment and storage process of two specific pieces: an Omani black velvet dress and a flower-printed scarf. Various forms of deterioration were observed, including dust, food and bodily oil stains, and snags. The conservation treatment processes involved repairing the snags, cleaning the oil stains around the neck and arms of the dress, and vacuuming the two objects based on their condition. To provide support, a new fabric was used for the textile. Additionally, a storage system was implemented to ensure long-term preservation. Throughout the entire conservation process, thorough photographic documentation was carried out. [ABSTRACT FROM AUTHOR]

Background/Aim. There are a few research papers in Serbia that report on the clinical results of scarf osteotomy (SO) and its long-term effects. The aim of this retrospective study was to evaluate the efficacy of SO in hallux valgus (HV) deformity correction, as well as the degree of recurrence and its possible causes. Methods. The study included 48 patients (52 feet) who underwent SO. The average follow-up time was 103.9 (63–156) months. In order to clinically evaluate the results, the American Orthopedic Foot and Ankle Society (AOFAS) scale and the Visual Analog Scale (VAS) of pain were used. In order to radiographically determine the degree of deformity, preoperative and postoperative radiographs of the feet were taken in the standing position, and the following parameters were determined: HV angle (HVA), intermetatarsal angle, distal metatarsal articular angle, and sesamoid position. Results. The AOFAS scores increased from 19 (5–45) points preoperatively to 92 (54–100) points at the time of the latest follow-up examination (p < 0.001). The VAS values significantly improved from 10 (8–10) preoperatively to 0 (0–6). The average HVA correction was 24.8°. The recurrence rate in patients in whom the HVA was greater than 20° was 26.9%. Conclusion. Although SO is a proven procedure for the correction of HV, long-term results still show a relatively high rate of recurrence. [ABSTRACT FROM AUTHOR]

In this study, tests were carried out on repaired 300 × 250 mm composite stiffened panels. The initial damage was assumed to be extended in a depth of the first six plies and a repair with scarf ratio of 1:50 was employed. A circular repair took place, utilizing laser-assisted ablation and the wet patches approach. The panels were tested in compression and Digital Image Correlation (DIC) and Acoustic Emission (AE) were used in order to monitor the damage initiation and propagation of the panels. In addition, Phased Array (PA) was used in order to monitor the patch failure. Detailed Finite Elements (FE) models were validated against the test findings and their performance as a prediction tool for the performance of repairs on composite aeronautical structures was assessed.

The purpose of this paper is to examine the human connection with nature, place, and the physical environment in Mohja Kahf's The Girl in the Tangerine Scarf (2006) in order to demonstrate the ways the Arab American author employs these themes to reflect the diasporic experience of her protagonist, providing (in)direct commentary on the wavering location of Arab Americans in repellent contexts, on the one hand, and offering readers a possible solution, on the other. This paper, then, explores the portrayal of nature, place, and environment in Kahf's novel as an active agent that accompanies the protagonist throughout the events of the plot to finally highlight the way she finds to reconcile with the world, blend differences, and find inner balance.

This paper presents the design rationale of a color-changing scarf depending on the emotional state it detects. The goal of the design is to associate people to show up their emotional state especially those who have difficulties in expressing their feelings, such as elderly people, children, people with special needs, and people who have to wear a face mask, which covers their facial expression, as it is common during the COVID-19 pandemic period. Wearing a smart emotional scarf provides a context of the individual's emotional state that might help surrounding people in dealing with them. Our design uses a heart rate sensor and a skin sensor to detect and recognize emotional information. The scarf will change its color based on the emotional state it detects (neutral, angry, happy, and sad). An interface allows the provision of emotional data and displays emotional statistics and daily history. We went through a user-centered design process adopting wearable technology guidelines. A proposed prototype of the smart scarf is presented called Scarfy. A user evaluation is conducted showing that wearing the scarf with changing colors based on emotional status is a good solution to express feelings with comfort and wearing it might enhance social engagement.

This experimental study investigates the effect of scarf geometry in restoring the impact response of scarf-patched 3 mm thick glass-fiber reinforced polymer (GFRP) matrix composite laminates. Traditional circular along with rounded rectangular scarf patch configurations are considered repair patches. Experimental measurements revealed that the temporal variations of force and energy response of the pristine specimen are close to that of circular repaired specimens. The predominant failure modes were witnessed only in the repair patch which includes matrix cracking, fiber fracture, and delamination, and no discontinuity in the adhesive interface was witnessed. When compared with the pristine samples, the top ply damage size of the circular repaired specimens are larger by 9.91%, while that of the rounded rectangular repaired specimens is larger by 434.23%. The results show that circular scarf repair is a more suitable choice of repair approach under the condition of a 37 J low-velocity impact event even though the global force-time response is similar.

We consider one-dimensional Dirac equation with rationally extended scalar potentials corresponding to the radial oscillator, the trigonometric Scarf and the hyperbolic Pöschl–Teller potentials and obtain their solution in terms of exceptional orthogonal polynomials. Further, in the case of the trigonometric Scarf and the hyperbolic Pöschl–Teller cases, a new family of Dirac scalar potentials is generated using the idea of parametric symmetry and their solutions are obtained in terms of conventional as well as exceptional orthogonal polynomials.

Today, composite materials, which have the advantage of strength and lightness ratio, have gained great importance especially in the aeronautical industry and automotive sector. With widespread use of composites, the repair of damages caused by external factors has also become an important research topic. In this study, the effects of different repair methods and scarf angles on the mechanical performance of the material were investigated. Scarf angles of 20°, 30°, and 45° have been selected in order not to create too many scarf areas and to find a quick repair method. Also, a comparison of single scarf and double scarf repair was made to find a more robust solution. The samples were produced from carbon fiber prepreg and with the [45/0/90/0/45]2s fiber orientation. Tensile, compression, and flexural (3-point bending) tests according to ASTM standards were applied to composite samples prepared with single scarf and double scarf repair configurations at different angles. The stress–strain curves obtained as a result of the tests showed that the specimens repaired at 20° had the highest strength. In addition, it has been determined that the samples repaired with double scarf withstand higher forces compared to the samples repaired with single scarf at the same angle. [ABSTRACT FROM AUTHOR]

Previous studies show that the adhesive strength can be expressed as a constant value of the critical ISSF (Intensity of Singular Stress Field) for several butt joints and lap joints. This study deals with the scarf joints where two distinct singular stress fields appear at the interface end. How to evaluate the scarf joint strength is described in comparison with the lap joint where two singular stress fields appear but the second singular stress field is weak. It is found that the adhesive strength of the scraf joints can also be expressed as a constant value of one of the ISSF like other joints. When two singular stress fields are comparable, the debonding strength of the scarf joints can be expressed at a certain point of the sum of the two singular stress fields as σ θ c (10 μ m) = const.

Scarf patching is the preferred technique for repairing physically damaged aircraft composite structures. The commonly used patch design is a circular conical frustum with a 3°optimized scarf angle. However, for this repair patch design the volume of material removed from the repaired composite panel can be quite large. This paper examines the effects of the different parameters on the stress state in the patch adhesive, such as ply orientation, stacking sequence, ply thickness and scarf angle. It explores an adaptive design of the repair patch for orthotropic materials and composite laminates, using 3D Finite Element Analysis. The design optimization approach is based on the evaluation of a Failure Criterion Index (FCI) and the minimization of its Relative Standard Deviation (RSD). An optimized scarf shape, which takes into account biaxial tensile loading conditions, fiber direction, and stacking sequence, is an elliptical conical frustum that induces a variable scarf angle along the sweeping angle. This design showed that less parent material is removed than that of the circular shape (decreased by up to 41%) and that the shear stress dispersion in the adhesive was significantly reduced (RSD decreased by up to 18%). The optimization method and the improved shapes are presented and discussed with respect to the influencing parameters. [ABSTRACT FROM AUTHOR]
