Long Head of the Biceps Tendinopathy: Diagnosis and Management (2010)

Tendinopathy of the long head of the biceps brachii encompasses a spectrum of pathology ranging from inflammatory tendinitis to degenerative tendinosis. Disorders of the long head of the biceps often occur in conjunction with other shoulder pathology. A thorough patient history, physical examination, and radiographic evaluation are necessary for diagnosis. Nonsurgical management, including rest, nonsteroidal anti-inflammatory drugs, physical therapy, and injections, is attempted first in patients with mild disease. Surgical management is indicated for refractory or severe disease. In addition to simple biceps tenotomy, a variety of tenodesis techniques has been described. Open biceps tenodesis has been used historically. However, promising results have recently been reported with arthroscopic tenodesis.
Mitochondria and vesicles differ between adult and prepubertal sheep oocytes during IVM (2014)

Oocytes from prepubertal animals have a reduced ability to undergo normal embryo development and produce viable offspring. The correct quantity, activity and cytoplasmic distribution of oocyte organelles are essential for oocyte maturation, fertilisation and subsequent embryo development. The aim of this study was to quantify the ultrastructural differences between oocytes from prepubertal lamb and adult ewes using electron microscopy and stereology. We also determined whether quantitative polymerase chain reaction (qPCR) methods give comparable estimates of mitochondrial number to stereology. Mean storage vesicle volume was greater in adult compared with lamb oocytes before IVM and decreased during maturation in both adult and lamb oocytes. Mitochondrial volume and number increased in adult oocytes during maturation; however, no increase was observed in lamb oocytes. Mitochondrial DNA copy number measured by qPCR showed no differences between adult and lamb oocytes. A different distribution of mitochondria was observed in lamb oocytes before maturation, while the percentage of hooded mitochondria increased during maturation in adult oocytes and decreased in the lamb. In conclusion, the present study has identified differences in the vesicles and mitochondria between adult and lamb oocytes from ewes that may contribute to reduced developmental competence in prepubertal oocytes.
Stability of the interorbital-hopping mechanism for ferromagnetism in multi-orbital Hubbard models (2023)

Abstract The emergence of insulating ferromagnetic phase in iron oxychalcogenide chain system has been recently argued to be originated by interorbital hopping mechanism. However, the practical conditions for the stability of such mechanism still prevents the observation of ferromagnetic in many materials. Here, we study the stability range of such ferromagnetic phase under modifications in the crystal fields and electronic correlation strength, constructing a theoretical phase diagram. We find a rich emergence of phases, including a ferromagnetic Mott insulator, a ferromagnetic orbital-selective Mott phase, together with antiferromagnetic and ferromagnetic metallic states. We characterize the stability of the ferromagnetic regime in both the Mott insulator and the ferromagnetic orbital-selective Mott phase forms. We identify a large stability range in the phase diagram at both intermediate and strong electronic correlations, demonstrating the capability of the interorbital hopping mechanism in stabilizing ferromagnetic insulators. Our results may enable additional design strategies to expand the relatively small family of known ferromagnetic insulators.

Simulations and Experiments on Low-Pressure Permeation of Fabrics: Part II The Variable Gap Model and Prediction of Permeability (2001)

Use of the creeping flow assumption provides a computationally efficient and accurate means of predicting flow fronts in reinforcement media in many technologically important polymer processes. In the case of fabrics, this creeping flow is shown to proceed primarily through the gaps in fabrics, with capillarity playing little if any role for commonly used materials. This finding has important implications for selection of strategy in modeling manufacturing processes of such materials. Namely, in the presence of fabric deformation which induces local shear, changes in the gap architecture greatly affect the flow patterns, and are not well predicted by tensor transformation of Darcy-type permeabilities. A simple, classic flow model is adapted to the case of fabrics penetrated by low-pressure viscous liquids after careful analysis of fabric architecture. An applicability range of this creeping flow model, the variable gap model, is developed. The present paper gives the model assumptions, and confirmation of its agreement with more sophisticated calculations. A demonstration of the approach for an unbalanced fabric (Knytex 24 5×4 unbalanced plain-woven glass fabric) shows excellent prediction of the bounds on flow behavior, and supports our earlier experimental findings on flow front orientation. This approach also shows clear superiority to semi-empirical, geometry-based models, since no fitting parameters at all are used in the modeling: only the constituent materials' geometry and properties are needed. This methodology is better able to predict trends in flow fronts, both qualitatively and quantitatively, than semi-empirical fitting. Extension of this work to realistic production processes is planned.
Estimation of Buffer Capacity in Various Solution for Simulated Well Condition (2014)

Abstract In order to evaluate corrosion behavior in oil and gas field conditions, it is important to simulate the corrosion condition in a laboratory test. The parameters for indicating the severity of corrosion, partial pressure of hydrogen sulfide and carbon dioxide, temperature, concentration of chloride ions, and pH of the solution should be taken into consideration. Among these parameters, pH of the solution is a controlling variable that can fluctuate during the test. To minimize pH fluctuation, test methods using a buffer system are widely adopted. But at the site such as initiating pit, the pH decreases locally because of acidity from proton formed by hydrolysis reaction. So the pH fluctuating behavior is also significant for depassivation process of localized corrosion. In this research, estimation of buffer capacity was conducted for some buffering systems. Corrosion tests of a corrosion resistant alloy such as martensitic stainless steel were carried out to determine the corrosiveness in a variety of buffer systems. In addition to the results, buffer capacities, which are resistances to pH change in the solution, were calculated by chemical thermodynamics. The validation of a buffer system that can simulate an actual oil and gas condition will be discussed.
Safety of Tofacitinib for Treatment of Ulcerative Colitis, Based on 4.4 Years of Data From Global Clinical Trials (2018)

In safety analyses of patients with moderate to severe UC treated with tofacitinib, we observed a dose relationship with herpes zoster infection. Although follow-up time was relatively short, the safety profile of tofacitinib for patients with UC appeared similar to that reported for patients with rheumatoid arthritis and for patients with UC treated with biologic agents, except for the higher IR of herpes zoster infection.

Shear band evolution and accumulated microstructural development in Cosserat media (2004)

Abstract This paper prepares the ground for the continuum analysis of shear band evolution using a Cosserat/micropolar constitutive equation derived from micromechanical considerations. The nature of the constitutive response offers two key advantages over other existing models. Firstly, its non‐local character obviates the mathematical difficulties of traditional analyses, and facilitates an investigation of the shear band evolution (i.e. the regime beyond the onset of localization). Secondly, the constitutive model parameters are physical properties of particles and their interactions (e.g. particle stiffness coefficients, coefficients of inter‐particle rolling friction and sliding friction), as opposed to poorly understood fitting parameters. In this regard, the model is based on the same material properties used as model inputs to a discrete element (DEM) analysis, therefore, the micromechanics approach provides the vehicle for incorporating results not only from physical experiments but also from DEM simulations. Although the capabilities of such constitutive models are still limited, much can be discerned from their general rate form. In this paper, an attempt is made to distinguish between those aspects of the continuum theory of localization that are independent of the constitutive model, and those that require significant advances in the understanding of micromechanics.

RELAXATION OF MICRO INDENTATIONS IN CALCIUM OXALATE URINARY STONES (1999)

The relaxation phenomena may have a practical implementation when considering repeat shock wave lithotripsy. A significant fraction of the energy invested in a stone which did not cause fracture or critical cracks is lost within 1 to 2 weeks after the procedure, particularly in elastic stones with a high organic matrix content. We suggest that the preferred interval for repeat shock wave lithotripsy be less than 2 weeks.

Palladium(II) Catalyst Systems for the Addition of Boronic Acids to Bicyclic Alkenes:  New Scope and Reactivity (2003)

[reaction: see text] The palladium-catalyzed ring-opening addition of arylboronic acids to heterobicyclic alkenes is reported. Excellent yields are obtained for the addition of a wide variety of arylboronic acids to aza- and oxabicyclic alkenes. This methodology is especially useful in the synthesis of 1-amino-2-aryldihydronaphthalene scaffolds, for which rhodium catalysts are currently unreactive or give complex mixtures. Asymmetric versions of these reactions are under development, and preliminary results are reported.
High-Performance MOS Tunneling Cathode with CoSi<sub>2</sub> Gate Electrode (2001)

The high performance of metal-oxide-semiconductor (MOS) tunneling cathodes with CoSi 2 gates was demonstrated. First, the deposition process of CoSi 2 was optimized. Stoichiometric CoSi 2 films were formed by codeposition with Co and Si. The electrical measurement suggested that deposition above 300°C was necessary to obtain low-resistivity silicide films. Second, operation characteristics were evaluated for MOS tunneling cathodes with CoSi 2 gates formed at 400°C. The emission efficiency increased with decreasing gate thickness and became as high as 1.5 ×10 -3 for the 5 nm CoSi 2 cathode. The efficiency did not depend on the electric field above 8.5 MV cm -1 . Thus, the CoSi 2 gates were deemed suitable for operation at higher electric fields to obtain larger emission currents. The lifetime of the cathodes corresponded to 500 h for operation at 8.5 MV cm -1 .
Effect of Temperature and Grain Size on the Corrosion Behavior of 316L Stainless Steel in Seawater (2011)

The corrosion behavior of 316L stainless steel was investigated in seawater at different temperature by using cyclic anodic polarization. The results indicated that two 316L specimens with different grain size showed similar pitting potential at 25°C. The increase of seawater temperature led to the linear decrease of pitting potential and repassivation potential. Because the pitting resistance of fine grain steel reduced larger than that of coarse grain steel with increasing temperature, the latter had a higher pitting potential about 60 mV at 85°C. Compared with the coarse grain steel, the fine grain steel showed a longer induction time for pitting at 65°C.
Algorithms for the partitioned solution of weakly coupled fluid models for cardiovascular flows (2011)

SUMMARY The main goal of this work is to devise robust iterative strategies to partition the solution of the Navier–Stokes equations in a three‐dimensional (3D) domain, into non‐overlapping 3D subdomains, which communicate through the exchange of averaged/integrated quantities across the interfaces. The novel aspect of the present approach is that at coupling boundaries, the conservation of flow rates and of the associated dual variables is implicitly imposed, entailing a weak physical coupling. For the solution of the non‐linear interface problem two strategies are compared: relaxed fixed‐point and Newton iterations. The algorithm is tested in several configurations for problems ranging from academic ones to some related to the computational haemodynamics field, which involve more than two components at each coupling interface. In some cases, it is shown that relaxed fixed‐point methods are not convergent, whereas the Newton method leads in all tested cases to convergent schemes. One of the appealing aspects of the strategy proposed here is the flexibility in the setting of boundary conditions at the interfaces, where no hierarchy is established a priori (unlike Gauss–Seidel methods). The usefulness of this methodology is also discussed in the context of dimensionally heterogeneous coupling and preconditioning for domain decomposition methods.

Eukaryotic Cell Toxicity and HSA Binding of [Ru(Me4phen)(bb7)]2+ and the Effect of Encapsulation in Cucurbit[10]uril (2018)

The toxicity (IC<sub>50</sub>) of a series of mononuclear ruthenium complexes containing bis[4(4'-methyl-2,2'-bipyridyl)]-1,<i>n</i>-alkane (bb<sub>n</sub>) as a tetradentate ligand against three eukaryotic cell lines-BHK (baby hamster kidney), Caco-2 (heterogeneous human epithelial colorectal adenocarcinoma) and Hep-G2 (liver carcinoma)-have been determined. The results demonstrate that <i>cis</i>-α-[Ru(Me<sub>4</sub>phen)(bb<sub>7</sub>)]<sup>2+</sup> (designated as α-Me<sub>4</sub>phen-bb<sub>7</sub>, where Me<sub>4</sub>phen = 3,4,7,8-tetramethyl-1,10-phenanthroline) showed little toxicity toward the three cell lines, and was considerably less toxic than <i>cis</i>-α-[Ru(phen)(bb<sub>12</sub>)]<sup>2+</sup> (α-phen-bb<sub>12</sub>) and the dinuclear complex [{Ru(phen)<sub>2</sub>}<sub>2</sub>{μ-bb<sub>12</sub>}]<sup>4+</sup>. Fluorescence spectroscopy was used to study the binding of the ruthenium complexes with human serum albumin (HSA). The binding of α-Me<sub>4</sub>phen-bb<sub>7</sub> to the macrocyclic host molecule cucurbit[10]uril (Q[10]) was examined by NMR spectroscopy. Large upfield <sup>1</sup>H NMR chemical shift changes observed for the methylene protons in the bb<sub>7</sub> ligand upon addition of Q[10], coupled with the observation of several intermolecular ROEs in ROESY spectra, indicated that α-Me<sub>4</sub>phen-bb<sub>7</sub> bound Q[10] with the bb<sub>7</sub> methylene carbons within the cavity and the metal center positioned outside one of the portals. Simple molecular modeling confirmed the feasibility of the binding model. An α-Me<sub>4</sub>phen-bb<sub>7</sub>-Q[10] binding constant of 9.9 ± 0.2 × 10<sup>6</sup> M<sup>-1</sup> was determined by luminescence spectroscopy. Q[10]-encapsulation decreased the toxicity of α-Me<sub>4</sub>phen-bb<sub>7</sub> against the three eukaryotic cell lines and increased the binding affinity of the ruthenium complex for HSA. Confocal microscopy experiments indicated that the level of accumulation of α-Me<sub>4</sub>phen-7 in BHK cells is not significantly affected by Q[10]-encapsulation. Taken together, the combined results suggest that α-Me<sub>4</sub>phen-7 could be a good candidate as a new antimicrobial agent, and Q[10]-encapsulation could be a method to improve the pharmacokinetics of the ruthenium complex.

Charging and Discharging Mechanisms of Organic Bistable Devices Based on ZnO Nanoparticles Capped with a Poly N-Vinylcarbazole Polymer (2011)

Scanning electron microscopy and energy-dispersive spectrometer images of hybrid nanocomposites of ZnO nanoparticles capped with a poly N-vinylcarbazole (PVK) that was fabricated using the spin-coating technique showed that the ZnO nanoparticles were capped with a PVK polymer layer. The measurement of the current-voltage (I-V) of the Al/ZnO nanoparticles capped with a PVK layer/indium-tin-oxide/glass devices at 300 K showed electrical bistability and negative differential resistance, which indicate the nonvolatile nature of the memory effect of the electron captured in the ZnO nanoparticles. The charging and discharging mechanisms of the organic bistable devices that were fabricated using hybrid nanocomposites of ZnO nanoparticles capped with a PVK layer are described based on the I-V results.
Systematic studies of the structural and optoelectronic characteristics of CaZn<sub>2</sub>X<sub>2</sub>(X = N, P, As, Sb, Bi) (2017)

Structural, electronic and optical properties of CaZn2X2 (X = N, P, As, Sb, Bi) Zintl compounds are investigated using all electrons full potential linearized augmented plane wave method. The unit cell volume of the compounds is optimized by generalized gradient approximation (GGA). For electronic and optical properties modified Becke Johnson exchange potential alongwith the GGA is used. It is observed that the band gap decreases by changing the anion X from N to Bi. All compounds show band gap except CaZn2Bi2 compound, which show metallicity. We have thoroughly discussed the absorption coefficient, optical conductivity, refractive index, birefringence and reflectivity. Static value of refractive index shows inverse variation with band gap. These Zintl compounds reveal strong interband transitions in the visible and ultraviolet energy regions.
Solid State Circuit Breaker design with discrete SiC MOSFET’s for Aircraft Electrification Application (2021)

Paralleling discrete FETs and achieving acceptable current sharing is a challenge since it is difficult to achieve perfect symmetry related to circuit layout and due to the component variations caused by manufacturing limitations. Hence, high-voltage, high-current switching power converter/motor drives utilize power semiconductor modules more often than paralleling multiple discrete components to achieve different design requirements. However, for certain applications, such as solid-state circuit breakers, discrete paralleling option may be feasible as there is no continuous ON/OFF switching operation of the power switches. The study in this paper proposes a symmetrical design for paralleling six discreate FET’s for a solid-state circuit breaker application. Initially, a symmetrical layout is proposed to achieve near identical impedances between all of the FETs and a simulation study is performed in LTspice to verify the current sharing performance. Secondly, a simulation model is developed to highlight the importance of DC resistance of the bus bar for current sharing between FETs. Thirdly, an experimental prototype is developed using SiC FETs, and the transient current sharing performance is analyzed for different DC resistance conditions. Finally, conclusion remarks are made to highlight major design constrains in paralleling of discreate FETs and ways to overcome such challenges.
