Orthopaedic Procedure Volume and Patient Outcomes (2007)

The association between greater hospital procedure volumes and improved patient outcomes has been well established with respect to a variety of procedures and treatments. However, this association in orthopaedics has not been summarized systematically. We reviewed existing literature on associations between hospital and surgeon procedure volume and patient outcomes in orthopaedic surgery. The patient outcomes examined were mortality, hip dislocation, infection, revision, complications, functional outcome, and satisfaction. Of the 26 articles reviewed, most examined outcomes after primary joint arthroplasties (predominantly hip arthroplasties) with a relatively limited number of studies examining revision arthroplasties, hip fractures, spine, or general orthopaedics. No studies evaluated any other subspecialties. We found an association between higher hospital volumes and lower rates of mortality and hip dislocation. We also found an association between higher surgeon volume and lower rates of hip dislocation. All other associations were negative or inconclusive. In addition, surgeon volume had a greater effect on patients than hospital volume for primary and revision joint arthroplasties, whereas hospital volume was more strongly related to outcome than surgeon volume for the other procedures examined. Our findings suggest the need for additional studies in the various subspecialties to establish more definitive conclusions.

Seroconversion Rates of Helicobacter pylori Infection in Korean Adults (2013)

The annual seroconversion rate was 2.79% in our study population. Marriage and living with H. pylori-infected family members were important risk factors affecting seroconversion in our adult population.
Moment-based inference predicts bimodality in transient gene expression (2012)

Recent computational studies indicate that the molecular noise of a cellular process may be a rich source of information about process dynamics and parameters. However, accessing this source requires stochastic models that are usually difficult to analyze. Therefore, parameter estimation for stochastic systems using distribution measurements, as provided for instance by flow cytometry, currently remains limited to very small and simple systems. Here we propose a new method that makes use of low-order moments of the measured distribution and thereby keeps the essential parts of the provided information, while still staying applicable to systems of realistic size. We demonstrate how cell-to-cell variability can be incorporated into the analysis obviating the need for the ubiquitous assumption that the measurements stem from a homogeneous cell population. We demonstrate the method for a simple example of gene expression using synthetic data generated by stochastic simulation. Subsequently, we use time-lapsed flow cytometry data for the osmo-stress induced transcriptional response in budding yeast to calibrate a stochastic model, which is then used as a basis for predictions. Our results show that measurements of the mean and the variance can be enough to determine the model parameters, even if the measured distributions are not well-characterized by low-order moments only--e.g., if they are bimodal.
Current intraoperative storage and handling practices of autologous bypass conduit: A survey of the royal australasian college of surgeons (2022)

During bypass surgery for peripheral arterial occlusive disease and ischaemic heart disease, autologous graft conduit including great saphenous veins and radial arteries are frequently stored in solution. Endothelial damage adversely affects the performance and patency of autologous bypass grafts, and intraoperative graft storage solutions have been shown to influence this process. The distribution of storage solutions currently used amongst Cardiothoracic and Vascular Surgeons from Australia and New Zealand is not well defined in the literature. The aim of this study was to determine current practices regarding autologous graft storage and handling amongst this cohort of surgeons, and discuss their potential relevance in the context of early graft failure. From this survey, the most frequently used storage solutions were heparinized saline for great saphenous veins, and pH-buffered solutions for radial arteries. Duration of storage was 30-45 min for almost half of respondents, although responses to this question were limited. Further research is required to investigate whether ischaemic endothelial injury generates a prothrombotic state, whether different storage media can alter this state, and whether this is directly associated with clinical outcomes of interest such as early graft failure.
Evaluation of embolic deflection devices using optical particle tracking (2013)

Trans-aortic valve replacement is a new endovascular procedure which has started to be used routinely in cardiac interventional suites. During such procedures a stent-like device containing new aortic valves is placed over the damaged ones, possibly causing calcifications to be dislodged and released in arteries leading to stroke. To prevent such events, new devices are being developed to provide distal protection to the brain supplying arteries. Currently there is a need to evaluate such device efficacy in a repeatable manner. We are proposing and investigating such a method based on particle optical tracking. We simulated such protective devices using two porous screens (150 and 200 μm pore size) which were placed in an arterial bifurcation phantom connected to a clinically relevant flow loop. A mask was acquired and gold embolic particles (100-300μm) were injected at a steady rate using a motorized injector. Optical images with 2 ms exposure were acquired at 30 fps. Images were subtracted, thresholded and filtered using a 5×5 median filter. ROI's were drawn over the main and bifurcating arteries and a particle counting algorithm was used to estimate particle flow rates in each artery for each run. The unprotected and the two protected cases were evaluated. Before filter placement, the particle flow rate was 60 and 40 %, respectively, of the main artery. After the filter placement, the particle flow rate in the protected branch was 4% and 8% of the particle flow rate in the main artery. We present a method to assess the efficacy of such devices using an optical particle tracking and counting technique.
Magnetism of Kitaev spin-liquid candidate material RuBr$_3$ (2021)

The ruthenium halide $α$-RuCl$_{3}$ is a promising candidate for a Kitaev spin liquid. However, the microscopic model describing $α$-RuCl$_{3}$ is still debated partly because of a lack of analogue materials for $α$-RuCl$_{3}$, which prevents tracking of electronic properties as functions of controlled interaction parameters. Here, we report a successful synthesis of RuBr$_{3}$. The material RuBr$_{3}$~possesses BiI$_3$-type structure (space group: $R\overline{3}$) where Ru$^{3+}$ form an ideal honeycomb lattice. Although RuBr$_{3}$ has a negative Weiss temperature, it undergoes a zigzag antiferromagnetic transition at $T_\mathrm{N}=34$ K, as does $α$-RuCl$_{3}$. Our analyses indicate that the Kitaev and non-Kitaev interactions can be modified in ruthenium trihalides by changing the ligand sites, which provides a new platform for exploring Kitaev spin liquids.
Distinct Effects of the UvrD Helicase on Topoisomerase- Quinolone-DNA Ternary Complexes (2000)

Quinolone antibacterial drugs target both DNA gyrase (Gyr) and topoisomerase IV (Topo IV) and form topoisomerase-quinolone-DNA ternary complexes. The formation of ternary complexes results in the inhibition of DNA replication and leads to the generation of double-strand breaks and subsequent cell death. Here, we have studied the consequences of collisions between the UvrD helicase and the ternary complexes formed with either Gyr, Topo IV, or a mutant Gyr, Gyr (A59), which does not wrap the DNA strand around itself. We show (i) that Gyr-norfloxacin (Norf)-DNA and Topo IV-Norf-DNA, but not Gyr (A59)-Norf-DNA, ternary complexes inhibit the UvrD-catalyzed strand-displacement activity, (ii) that a single-strand break is generated at small portions of the ternary complexes upon their collisions with UvrD, and (iii) that the majority of Topo IV-Norf-DNA ternary complexes become nonreversible when UvrD collides with the Topo IV-Norf-DNA ternary complexes, whereas the majority of Gyr-Norf-DNA ternary complexes remain reversible after their collision with the UvrD helicase. These results indicated that different DNA repair mechanisms might be involved in the repair of Gyr-Norf-DNA and Topo IV-Norf-DNA ternary complexes.
Design and Implementation of a X-band Dual-polarization Phased-array Antenna (2018)

The paper proposes a X-band dual-polarization phased-array antenna based on the vivaldi antenna. As known, the traditional correlation interferometer direction finding system cannot accurately determine the direction of the direct wave, when the wave is mixed with the reflected signals. As an important part of this system, the antenna is improved to solve this problem. The phased-array antenna consists of two sets of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6\times 6$</tex> array antennas, seventy-two phase shifters, fourteen power dividers and a switch circuit. Each <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6\times 6$</tex> array antennas is composed of thirty-six vivaldi antennas. The two sets of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6\times 6$</tex> array antennas are placed orthogonally to each other, so the vertical polarization and horizontal polarization are achieved. Each vivaldi antenna is followed by a phase shifter in order to achieve beam scanning. The six-way power divider has a current amplitude ratio of 0.32:0.6918:1:1:0.6918:0.32 according to the principle of Taylor array. The switch circuit is applied to choose polarization mode. The simulation results show that the −10 dB bandwidth of the antenna is extended covers X-band from 9.6 to 11.1 GHz, gain of the antenna is more than 20dB, and the side-lobe is 13.7dB, 14.0dB and 13.2dB lower than the main lobe in directivity diagram of the E-plane at 10GHz when the electrical scanning is 0deg, 10deg and 20deg, respectively. It is suitable for application of X-band phased-array antenna.
Effect of Constrained Conditions on the Equivalent Strain and Microstructure of 5052 Al Alloy Deformed by Groove Pressing (2013)

Three-dimensional finite element simulation (3D FES) and experiments were carried out for analyzing the deformation behavior, homogeneity, microstructure and properties of 5052 Al alloy during groove pressing (GP) with two different processing conditions, that is, constrained groove pressing (CGP) and unconstrained groove pressing (UGP). The simulation results show that the values of the equivalent strain and its distribution depend strongly on the constrained conditions. Especially, the equivalent strain and its distribution are inhomogeneous along X direction, with lower strain regions located at both ends and larger strain regions with periodic variation located at intermediate section. CGP results in a higher accumulative rate of equivalent strain than that of UGP. The average strain is equal to the theoretical strain for CGP, but it is much lower than its theoretical strain for UGP. The experimental results show that grain sizes of 5052 Al alloy can be refined significantly by CGP or UGP, while CGP has a higher rate of grain refinement and finer grains than that of UGP. And the results of microhardness confirmed the prediction of 3D FES.
Optical Fiber Sources Design in OptiSystem Software (2022)

OptiSystem software is a tool that is well suited for conducting numerical simulations for designing fiber lasers. Novel pumping scheme for holmium-doped fiber amplifier (HDFA) using commercially available 980nm and 1480nm laser diodes is proposed using cascaded fiber lasers. The first fiber laser uses erbium-doped fiber to generate a continuous-wave (CW) laser at 1620nm, while the second fiber laser uses thulium-doped fiber to generate a CW laser at 1950nm, which is used to pump the HDFA.

Defeating pharming attacks at the client-side (2011)

With the deployment of “always-connected” broadband Internet access, personal networks are a privileged target for attackers and DNS-based corruption. Pharming attacks - an enhanced version of phishing attacks - aim to steal users' credentials by redirecting them to a fraudulent login website, using DNS-based techniques that make the attack imperceptible to the end-user. In this paper, we define an advanced approach to alert the end-user in case of pharming attacks at the client-side. With a success rate over 95%, we validate a solution that can help differentiating legitimate from fraudulent login websites, based on a dual-step analysis (IP address check and webpage content comparison) performed using multiple DNS servers information.
Music and Reading (2012)

Increasingly, music teachers are required to assist, tutor, or teach reading skills in the music classroom. In the effort to meet such mandates, music teachers may be challenged to either relinquish valuable music instruction time or attempt to combine instructional strategies of both music and reading into singular lessons, units, and classroom activities. It may prove beneficial for music educators to understand common characteristics inherently shared between the two subjects. This article details terminology, learning processes, and instructional strategies shared between music and reading instruction. Activities demonstrate ways reading instruction is naturally supported in the music classroom.
Development of the sheep conceptus during the first fourteen days. (1966)

This paper describes the development of conceptuses obtained from animals in which the onset of estrus was known to within about 8 hours. Also the viability of conceptuses of similar age but variable sizes was studied after transfer to recipient ewes. There were 177 donor ewes superovulated with 800-1000 I.U. pregnant mares serum on Day 12 of the cycle. Conceptuses were removed by operation between Days 5 and 9 in 86 and between Days 12 and 14 in 91 with Day 0 the onset of estrus although ovulation normally takes place 24 hours later. 521 developing conceptuses and 81 unfertilized eggs were recovered. (47 of the unfertilized eggs were from ewes showing an exaggerated response to gonadotrophin with more than 20 ovulations per animal. ) 97 morulae were recovered 95 between the ages of 112 to 128 hours postestrum 2 at 160 hours. There were 30 in the 16-32 cell stage and 67 in the 32-64 cell stage. The development of a central cavity determined the blastocyst stage ovserved in 190 recovered from 128 to 224 hours after estrus. Some were still within the intact zona pellucida. Others were larger with no zona pellucida. By 208 hours postestrum the blastocysts showed a prominent embryonic disc. In the third phase of development many were damaged by recovery methods but 123 were obtained undamaged. At about Day 12 the conceptus begins to elongate and within 24 hours changes to an elongated chorionic sac with the embryo clearly discernable. The enlongating process continues rapidly but the embryonic disc enlarges only slightly. On Day 12 some degree of damage to embryonic membranes was tolerated when conceptuses were transferred to suitable recipients. When of the same age transferred conceptuses did equally well irrespective of different sizes but had all remained within the donor uterus many would have degenerated and died due to the competition. The marked growth of the conceptus from Day 12 to Day 14 postertrus commences when the corpus luteum becomes dependent on the presence of the conceptus for its continued maintenance. Other experiments have shown that the sheep conceptus can develop until Day 11 even in rabbit oviducts but does not survive longer there.
The DBA.2 Mouse Is Susceptible to Disease following Infection with a Broad, but Limited, Range of Influenza A and B Viruses (2011)

We assessed the relative susceptibilities to disease of the DBA.2 and C57BL/6 mouse models upon infection with a range of influenza A and B viruses. DBA.2 mice were more susceptible to disease upon inoculation with human H1N1 influenza A virus strains, several swine influenza viruses, and influenza B viruses but were not overtly susceptible to infection with human seasonal H3N2 strains. Hemagglutination inhibition and immunoglobulin isotype profiling indicated that DBA.2 and C57BL/6 mice generate comparable humoral responses upon equivalent 50% mouse lethal dose (MLD(50)) challenges with influenza virus. Our data demonstrate the utility of DBA.2 mice for the elucidation of influenza virus pathogenicity determinants and the testing of influenza vaccines.
TEMPLATE-BASED ISOCONTOURING (2006)

Different isocontour extraction methods use different cell types (tetrahedral, hexahedral, etc.) depending on the nature of the acquisition grids (structured, unstructured, etc.). The existing isocontouring methods have the following pre-steps for the actual extraction process: (a) identification of cell types, (b) identification of topologically independent instances for each cell type, (c) determination of surface primitives contained in the topologically independent instances and (d) generation of a lookup table such that the name of the entry is an instance of a cell and the entry is the triangle set for that instance. The extraction process outputs the triangles from the lookup table. In this paper we present a novel generic method that enables us to list topologically independent surface primitives called "templates" within any n-polytope cell namely tetrahedra, hexahedra etc. We have also modified the traditional lookup table such that name is the cell instance and the entry is face index representations of all template instances contained in that cell. To show an example, we have applied this approach on a hexahedron and listed the templates and subsequently we have showed how to construct a lookup table. Most modern graphics hardware render triangles faster if they are rendered collectively as triangle strips as opposed to individual triangles. With our modified lookup table approach we can identify triangles in the neighboring cell in a linear time and hence we are able to connect two triangle strips into a longer triangle strip on the fly during the extraction process. We have compared our approach with some existing methods. The following are some of the important features of the method: (1) Simplicity, (2) procedural triangulation and (3) face-index representation.
