Comparison of Coronal Prosthetic Alignment After Total Knee Arthroplasty Using 3 Computer-Assisted Navigation Systems (2018)

Recent advances in surgical tools such as navigation systems have contributed to accurate implantation in total knee arthroplasty. Although several navigation systems have been developed, reports regarding which navigation system has better accuracy are few. Therefore, this study aimed to compare the accuracy of postoperative coronal alignment among 3 navigation systems. A total of 90 knee prostheses were implanted for 90 patients with osteoarthritis. Thirty patients were enrolled in each of the following 3 navigation groups: Stryker Navigation System II (computed tomography-free navigation; Stryker, Mahwah, New Jersey); OrthoPilot version 4.2 navigation system (computed tomography-free navigation; B. Braun Aesculap, Tuttlingen, Germany); and VectorVision navigation system (computed tomography-based navigation system; BrainLAB, Munich, Germany). Thirty consecutive total knee arthroplasties performed via the conventional method without navigation were selected as a control group for comparison with the navigation groups. Postoperative coronal mechanical axis and femoral and tibial coronal component angles were compared among the groups using long-leg standing radiographs for the rate of outliers beyond 3°. No differences were observed in the mean femoral and tibial component angles among the navigation and conventional groups. However, the proportion of outliers beyond 3° was higher in the conventional group than in the 3 navigation groups. No significant differences in the outlying values were found among the 3 navigation groups. These 3 navigation systems achieved equally accurate coronal mechanical alignment with fewer outliers. The navigation systems exhibited more precise implantation than the conventional method. [Orthopedics. 2018; 41(5):e621-e628.].
Filament Winding (2001)

Abstract Filament winding is a process for fabricating a composite structure in which continuous reinforcements, either previously impregnated with a matrix material or impregnated during winding, is placed over a rotating form or mandrel in a prescribed way to meet certain stress conditions. This article describes the advancements in filament winding and lists the advantages and disadvantages of filament winding. It discusses the effects of fiber tension in filament winding and the selection of fibers, resins, and materials for filament winding. The article emphasizes the three basic filament-winding patterns, such as helical, polar, and hoop. It presents information on the applications of filament winding, including rocket motors, natural gas vehicle (NGV) tanks, and sporting goods. The article presents recommendations for the basic design guidelines for filament-winding design/manufacturing process and concludes with a discussion on fabrication recommendations.
Modulation Transfer Function Analysis of Kelvin Wakes and Ambient Wave Images (1991)

Synthetic aperture radar (SAR) images collected during a 1989 surface ship wake experiment are analyzed using a linear imaging model which includes contributions due to velocity bunching, tilt modulation and hydrodynamic modulation as well as azimuth falloff and coherent speckle effects. This model adequately predicts the overall shape of the image spectrum for ambient waves as observed from three different look directions, although there are some discrepancies for range-traveling waves which are attributed to uncertainties in the tilt and hydrodynamic modulation. Inversion of the model to yield estimates of the Kelvin wake and ambient wave heights appears to be successful, although the results are sensitive to the value assumed for the surface decorrelation time.
Presynaptic dysfunction caused by cerebrospinal fluid from a patient with the ataxic form of Hashimoto's encephalopathy (2014)

Abstract Background H ashimoto's encephalopathy is an autoimmune disease associated with H ashimoto's thyroiditis. The mechanism underlying the development of ataxia is unclear. Aim We examined whether impairment in synaptic transmission underlies the pathomechanism of H ashimoto's encephalopathy. Methods We tested the effects of cerebrospinal fluid from H ashimoto's encephalopathy patients on cerebellar synaptic transmission in rat cerebellar slices. The effects of cerebrospinal fluid from six patients with the ataxic form of H ashimoto's encephalopathy were examined using patch‐clamp recording in rat cerebellar slices. Results The cerebrospinal fluid of one patient, but not those of the other five patients, impaired presynaptic short‐term plasticity between parallel fiber‐ P urkinje cell transmission in the cerebellum. The patient whose cerebrospinal fluid induced presynaptic impairment had hypothyroidism with a high titer of anti‐thyroid antibodies, and was positive for anti‐ NH 2 ‐terminal of α‐enolase antibodies in the cerebrospinal fluid. Conclusions These results suggest that defective glutamate release is a potential pathomechanism in some patients with H ashimoto's encephalopathy.
5G networks enabling new smart grid protection solutions (2019)

Within the ongoing energy revolution, power distribution grid protection, control, and monitoring requires modern, advanced technologies to maintain safety and reliability of operation. If all devices could be interconnected through secure, reliable, and low latency communication infrastructure, a new dimension for design and operation of power distribution grids would be seen. Usually communication based protection and control schemes are built with wired communication technologies, which may be unavailable or difficult to arrange in retrofit scenarios. This paper introduces one of the most demanding communication-based protection principles - line differential protection including intertrip between circuit breakers, as a benchmark application for the evolved fifth generation (5G) wireless communication and an extensive test environment to validate its system and communication performance.
A new fire protection system of power cable tunnel based on wireless sensor network monitoring system (2016)

For existing problems and defects of power cable tunnel fire protection system, a new type of fire alarm and protection system was developed. Wireless transmission technology and distributed fire detection units are used to this system, and it can collect the real-time data of temperature, smoke concentration and the concentration of toxic gases. Two layer transmission network are set up to transmit the data collected by the wireless terminal devices while the GPRS network are used to remote data transmission. It is available to look up and query the data on the monitoring software. The operation state assessment of power cable could easily get from the historical data.
Study of electrical properties of Bi2O3-Fe2O3-P2O5 glasses investigated by impedance spectroscopy (2005)

Elektricna su svojstva bizmutovih željeznih fosfatnih stakala istraživana impedancijskom spektroskopijom. Fosfatna stakla množinskih sastava: 40Fe2O3-60P2O5, 3Bi2O3-38, 8Fe2O3-58, 2P2O5, 10Bi2O3-30Fe2O3-60P2O5, 20Bi2O3-20Fe2O3-60P2O5 istraživana su mjerenjem admitancije u frekvencijskom podrucju od 0, 01 Hz do 4 MHz i temperaturnom podrucju od 303 do 473 K. Elektricna provodnost bizmutovih željeznih fosfatnih stakala ovisi o množinskom udjelu Fe2O3, koncentraciji Fe(II) iona i udaljenosti između dva Fe atoma. Povecanjem Fe(II) koncentracije od 17 % do 35 % kod stakala koja sadrže do 10 mol% Bi2O3 elektricna dc provodnost raste. S druge strane, pad dc provodnosti za staklo koje sadrži 20 mol% Bi2O3 pripisuje se smanjenju kolicine Fe2O3 od 30 do 20 mol%, sto upucuje da dc provodnost u ovim staklima ovisi o kolicini Fe2O3, a neovisna je o kolicini Bi2O3. Elektronska vodljivost ovih stakala posljedica je prijelaza elektrona s Fe(II) na Fe(III) ione i stvaranja polarona. Povecanje elektricne vodljivosti unutar serije stakala prati smanjenje aktivacijske energije sto je posljedica stvaranja vece koncentracije polarona. Relaksacijska vremena i odgovarajuce energije aktivacije, također, ovise o koncentraciji nastalih polarona. Stakla s vecom koncentracijom Fe(II) iona pokazuju kraca relaksacijska vremena, te manju energiju aktivacije. Izracunate vrijednosti energije aktivacije za dc provodnost, Edc, i energije aktivacije, EZ, identicne su i upucuju da se radi o istom relaksacijskom procesu. Istraživana bizmutova željezna fosfatna stakla pokazuju elektronsku provodost.
Development of a polymer-based antimicrobial coating for efficacious urinary catheter protection (2020)

This study reports the development of a polymer-based catheter coating to facilitate controlled release of antimicrobial peptides (AMP) to target both planktonic bacteria and biofilm in the urinary catheter environment. Catheter associated urinary tract infection (CAUTI) is a common nosocomial infection among hospitalized patients and is a major reservoir of antimicrobial resistant pathogens. Although silver- or antibiotics-coated catheters have been deployed to minimise CAUTI, the inconsistency and lack of durability in antibacterial properties of these coatings have limited their clinical use. The incorporation of AMPs in catheter coatings has gained interest due to the effective bacteria killing effects of AMPs, with few reports on bacterial resistance development against peptides. This study aims to deploy a novel and potentially cost-effective technique to coat an anhydrous polymeric coating impregnated with AMPs for silicone-based catheters, to overcome limitations in conventional hydrogel-based coatings. Sustained peptide release was achieved with the development of an Ethyl Cellulose (EC): 1-Palmitoyl-2-oleoylphosphatidylcholine (POPC)-based diffusion layer over an AMP-laden Polycaprolactone (PCL)-based layer to control AMP diffusion into the environment over a clinically relevant duration. The ‘AMP-EC-PCL’ coating showed good anti-bacteria performance against uropathogenic Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa for up to 6 days. The coating also showed excellent anti-biofilm capability against green fluorescent protein (GFP)-tagged UTI E. coli. Fifteen centimeter catheter segments of single layer ‘AMP-EC-PCL’-coated catheters showed sustainable AMP release kinetics up to 7 days, where good antibacterial and anti-biofilm activity against E. coli was observed. The full scale ‘AMP-EC-PCL’-coated catheter showed improved mechanical integrity compared to commercial silicone catheters with preservation of the catheter balloon integrity upon expansion. Wound healing studies of the coated PDMS samples in mice models showed a reduction in bacteria concentration as compared to uncoated PDMS, indicating in vivo efficacy potential of the developed catheter coating platform.
Nonlinear dynamic characteristics of a three-dimensional rod-fastening rotor bearing system (2014)

The nonlinear dynamic characteristics of three-dimensional rod-fastening rotor bearing system are investigated in this paper. The rod-fastening rotor includes discontinuous shaft, rotating disks, circumferentially distributed rods, and macrointerfaces between disks. The first three parts are discretized by three dimensional elements, and the macrointerfaces are connected by some springs whose stiffness is determined by a proposed linear partition method. For comparison, the three-dimensional dynamic model of a corresponding complete rotor bearing system is also built. After the rod-fastening and complete rotor bearing system are reduced by a component mode synthesis, periodic motions and stability margins are calculated by using the shooting method and path-following technique, and the local stability of system is obtained by using the Floquet theory. Comparative results show the both systems have a resemblance in the bifurcation features when mass eccentricity and rotating speed are changed. The vibration response has the identical frequency components when typical bifurcations occur. The dynamic stress is obtained by regarding the displacements of all nodes as load. Moreover, the unbalanced and insufficient of the pre-tightening forces lead to obvious disadvantageous influence on the stability and vibration of the both systems. Generally, this paper considers the interfacial effect of the rod-fastening rotor bearing system and the relative nonlinear dynamic features are obtained.

Inkjet printing of single-walled carbon nanotubes and electrical characterization of the line pattern (2008)

Single-walled carbon nanotubes (SWCNTs) were patterned using inkjet printing. To make the uniform networks of dropped SWCNTs, the effects of substrate heating, surface hydrophilicity of the substrate and the jetting process were investigated. Circuit diagrams including holes, lines and curves were printed on glass and polymer substrates, and the conductive lines were printed on a glass substrate to characterize their electrical properties by I-V curve and impedance measurements. Lines 75 mm long were printed along with the number of overwrites with 150 µm linewidth and width change with five overwrites. As for the results, we confirmed that the dc resistance of the SWCNT line was proportionally changed according to the linewidth and the number of overwrites, and the line feature possessed ohmic characteristics to 2 MHz even after two overwrites.

Improving Nuclear Power Plant's Operational Efficiencies in the U.S.A. (2011)

This article discusses improvement in nuclear power plant’s operational efficiencies in the USA in the past 40 years. The increase in nuclear generation has been achieved by a substantial increase in the overall capacity factor of the US plants from about 60% in 1980 to over 90% today. This large increase in capacity factor was achieved by reducing outages, having longer fuel cycles, using higher burnup fuel, and reducing unplanned outages and fuel failures. Combined with increases in power in various plants, this allowed nuclear power to maintain and increase its share of electricity generation. Such an increase in nuclear generation is the equivalent of having built 25–30 nuclear power plants during that period. The length of the planned outages has reduced from 106 days for an average operating plant in 1991 to 38 days in 2008. The fuel performance has also improved to a very high level over the last 20–30 years.
Application of Beam Fanning in a Photorefractive BaTiO3 Crystal: Measurement of Light Scattering at Zero Degrees by a Single Glass Fiber (1991)

The photorefractive effect in BaTiO 3 has been the subject of extensive research in recent years. Because of very large electro-optic coefficients, BaTiO 3 has become a unique candidate for a variety of nonlinear optical devices which operate at very low light intensities. Most of these devices use energy transfer between coherent optical beams that interfere inside the crystal while some devices use the extinction of a single beam through beam fanning 1-3 .
A Biomimetic Approach to the Discorhabdin Alkaloids:  Total Syntheses of Discorhabdins C and E and Dethiadiscorhabdin D (1998)

The characteristic spirodienone structure of the discorhabdin alkaloids is readily formed by reaction of the tyramine-substituted indoloquinonimines 26, 35, and 36 with cupric chloride, triethylamine, and oxygen. This cyclization provides a possibly biomimetic route to discorhabdins C and E (41 and 42). The unbrominated spirodienone 40 reacts with hydrogen over Pd/C to give enone 46. Bromination at the alpha position gives a mixture of bromoenones that undergo smooth conversion to dethiadiscorhabdin D (4) upon treatment with basic alumina.
Chemistry of the SO bond. Part 11. trans,trans-4,6-Di-t-butyl-trans-5-methyl-1,3,2-dioxathiane 2-oxide and cis,cis-4,6-di-t-butyl-cis-5-methyl-1,3,2-dioxathiane 2-oxide, synthesis and crystal structure determination (1989)

Reduction by LiAlH4 of 2,2,4,6,6-pentamethylheptane-3,5-dione gives a mixture of diastereoisomeric diols, which upon cyclisation with thionyl chloride yields a mixture of isomeric 4,6-di-t-butyl-5-methyl-1,3,2-dioxathiane 2-oxide. From the distribution of the latter mixture, a small, but distinct stereoselectivity of the dione reduction is inferred, which in turn suggests a preference of the reacting dione for an extended conformation.Single crystal X-ray determinations have been performed on the two title compounds (components of the cyclic sulphite mixture) to establish their structure, conformation and geometry. The geometries are compared with currently available population averages of cyclic sulphites. The high substitution present in the title compounds does not show in the C–O–S(O)–O–C region of the ring, but reveals itself markedly in the C(4)–C(6) region and in the substituents.

Improving an Intelligent Detection System for Coronary Heart Disease Using a Two‐Tier Classifier Ensemble (2020)

Coronary heart disease (CHD) is one of the severe health issues and is one of the most common types of heart diseases. It is the most frequent cause of mortality across the globe due to the lack of a healthy lifestyle. Owing to the fact that a heart attack occurs without any apparent symptoms, an intelligent detection method is inescapable. In this article, a new CHD detection method based on a machine learning technique, e.g., classifier ensembles, is dealt with. A two-tier ensemble is built, where some ensemble classifiers are exploited as base classifiers of another ensemble. A stacked architecture is designed to blend the class label prediction of three ensemble learners, i.e., random forest, gradient boosting machine, and extreme gradient boosting. The detection model is evaluated on multiple heart disease datasets, i.e., Z-Alizadeh Sani, Statlog, Cleveland, and Hungarian, corroborating the generalisability of the proposed model. A particle swarm optimization-based feature selection is carried out to choose the most significant feature set for each dataset. Finally, a two-fold statistical test is adopted to justify the hypothesis, demonstrating that the performance differences of classifiers do not rely upon an assumption. Our proposed method outperforms any base classifiers in the ensemble with respect to 10-fold cross validation. Our detection model has performed better than current existing models based on traditional classifier ensembles and individual classifiers in terms of accuracy, <i>F</i> <sub>1</sub>, and AUC. This study demonstrates that our proposed model adds a considerable contribution compared to the prior published studies in the current literature.
Addition of Lenalidomide to Melphalan in the Treatment of Newly Diagnosed Multiple Myeloma: The National Cancer Institute of Canada Clinical Trials Group MY.11 Trial (2007)

Oral melphalan and prednisone remain an effective and tolerable treatment for patients with multiple myeloma. For approximately 40 years, this combination has been the standard of care for patients not proceeding to stem cell transplant. Within the last 10 years, new agents have been found to be efficacious in the relapsed/refractory setting. Within the last year, two trials of added thalidomide in the newly diagnosed setting have demonstrated outcomes superior to those achieved with melphalan and prednisone alone. This improved outcome comes at the cost of increased toxicity.The National Cancer Institute of Canada Clinical Trials Group (NCIC CTG) has recently developed a randomized phase ii trial (MY.11) that uses a combination of lenalidomide with melphalan for patients with newly diagnosed multiple myeloma. Lenalidomide is a thalidomide analogue and, like thalidomide, is thought to work through immunomodulatory effects. It was shown to have activity in patients with relapsed or refractory disease and, in combination with dexamethasone, is superior to dexamethasone alone. Lenalidomide holds promise as a more effective and potentially less toxic derivative of thalidomide. Experience with lenalidomide in combination with chemotherapy is very limited, and the purpose of MY.11 is to establish tolerability and to gain knowledge about efficacy. The information gained from MY.11 is expected to help inform dosing levels and schedules for a large phase iii trial being developed by the Eastern Cooperative Oncology Group that will include participation by the NCIC CTG.
