Smaller femoral neck anteversion in varus knees than in healthy and valgus knees (2022)

It is important to investigate anatomical differences of the femur and tibia three-dimensionally between varus and valgus knees to enhance surgical approaches and better understand structural factors related to specific patterns of osteoarthritis progression. Three-dimensional femoral and tibial bone models were reconstructed from transverse computed-tomography scans in varus osteoarthritis (43 knees), valgus osteoarthritis (40 knees), and healthy (32 knees) groups. Different coordinate systems were defined in each femoral bone model ("Knee" and "Hip" Coordinate System). Femoral neck inclination, lateral bowing, anterior bowing, and neck anteversion were measured and compared between knee and hip coordinate systems. Those parameters were also compared between varus, valgus, and healthy groups. The tibial anterior and lateral bowing, external torsion and the fibular axis relative to the tibial mechanical axis were measured and compared between varus and valgus groups. Femoral neck anteversion was significantly 1-2° greater in the hip coordinate system compared to the knee coordinate system. Femoral neck anteversion was significantly smaller in varus knees than in healthy or valgus knees, with average difference of approximately 5°. The knee and hip joint are often rotated externally relative to the trunk axis in patients with varus osteoarthritis, perhaps maintaining the geometric relations between pelvis and proximal femur (including peripheral hip muscles) regardless of knee deformities. The fibular axis was inclined slightly valgus and posteriorly in two groups. The results may inform hypotheses on, and future studies of, skeletal morphologic development and factors contributing to the progression of knee osteoarthritis.
Cloud-Edge Hosted Digital Twins for Coordinated Control of Distributed Energy Resources (2022)

This article presents a novel approach for realizing coordinated control of Distributed Energy Resources (DERs) based on cloud-hosted and edge-hosted digital twins (DTs) of DERs. DERs are playing an increasingly important role in supporting the frequency regulation of power systems with massive integration of renewable resources. However, due to the significant differences in DERs’ capability and characteristics, individual and un-coordinated responses from DERs could lead to a less effective overall response with undesirable traits, e.g., slow response, severe overshoots, etc. Therefore, the coordination of DERs is critical to ensure the desirable aggregated overall response. A major shortcoming of conventional centralized or distributed approaches is their significant reliance on real-time communications. This article addresses the challenges by the application of DTs that can be hosted in the cloud for the centralized control approach and the edge for the distributed approach to minimize the need for real-time communications, while being able to achieve the overall coordination among DERs. The proposed DT-based coordinated control is validated using a realistic real-time simulation test setup, and the results demonstrate that the DT-based coordinated control can significantly improve the aggregated DERs’ response, thus offering effective support to the grid during contingency events.
[Experimental studies of wound healing in the paranasal sinuses. II. Spontaneous wound healing and drug effects in a standardized wound model]. (1991)

A model of wound healing in the maxillary antrum of the rabbit was developed. The regeneration of standardized circular mucosal defects 4 mm in diameter was studied using conventional histology and serial sections as well as three-dimensional histomorphological analysis. Wound closure started by migration of epithelium; 24 h later mitoses were seen. 120 h after creation of the wound the granulation tissue covering the wound surface started to become hyperplastic, and bone apposition with formation of osteoid occurred. Systemic application of prednisolone i.m. (2 mg/kg per day) and topical administration of dexpanthenol-ointment (5%) resulted in an acceleration of the late epithelial wound closure together with a reduction of hyperplastic granulation tissue. Epidermal growth factor, applied locally, had no significant effect. The proposed animal model permits additional quantitative evaluation of postoperative treatment modalities.
Network Architectures for Delay Critical Industrial Wireless Sensor Networks (2013)

This chapter examines some industrial wireless sensor networks requirements specific to industrial settings, focusing on the communication challenges caused by the harsh deployment environments that are common in industrial settings, and the strict application requirements imposed by the real-time nature of the industrial processes. Monitoring applications are similar to the general use cases of sensor networks for monitoring a certain phenomenon. They usually involve tens of nodes that are strategically placed on pre-meditated locations to monitor a certain device, process, or physical property. An industrial automation and control system is a complex structure that supports various functionalities for fast, flexible, and easy management, configuration, and operation. The chapter focuses on communication related challenges coupled with the strict application requirements imposed by the nature of the control systems. A typical distributed control system, might contain a combination of different communication technologies.

Distance protection of asymmetrical overhead lines (1997)

Distance protection is based on the measurement of the impedance of power system short-circuit loops and the comparison with given settings. Conversion of the measured short-circuit impedances using kilometric impedance values allows distances to be evaluated. In any case, an ideally symmetrical line structure is assumed. In practice, however, such an ideal symmetry cannot be reached for overhead power lines, even if transposed. Complete transposition of an overhead line, for instance, is effective only in case of a short-circuit at the end of the line. Today, overhead lines often are not transposed to reduce costs. This paper shows how asymmetries of single- and double-circuit power lines can be taken into account when fault distances are determined using various compensation methods. The asymmetry is directly included in the process of modeling of the distance protection. (7 pages)

Functional Nanoparticles in Targeting Glioma Diagnosis and Therapies (2014)

Successful therapy and diagnosis of glioma is one of the biggest challenges in the biomedical fields. The incidence is growing gradually around the world. Annually, there are approximately 13,000 cases of glioblastoma multiforme diagnosed with historical 1-year and 5-year survival rates of 29.3% and 3.3%, respectively. The prognosis of patients with malignant glioma remains dismal. Due to its highly proliferative, infiltrative, and invasive property, development of effective preventative strategies to control the gliomas is in high demand. Meanwhile, the efficiency of drug delivery to glioma remains low owing to the non-specific, non-targeted nature of anti-tumor agents. Furthermore, the presence of the blood brain barrier and blood brain tumor barrier is another obstacle for gliomas treatments. Nanotechnology has brought a paradigm shift in the diagnosis and treatment of glioma. This review discusses the potential of various nanoparticles in the diagnosis of gliomas using some metal oxide, and in the therapy of gliomas including receptor-mediated, magnetic directing, and cell-mediated drug delivery systems. In this review, some physical techniques combined with nanoparticles (NPs) such as ultrasound therapy, thermochemotherapy, photodynamic therapy, and fluorescent magnetic NPs have also been summarized.

Effect of bubble deformation on the properties of bubbly flows (2003)

Direct numerical simulations of the motion of 27 three-dimensional deformable buoyant bubbles in periodic domains are presented. The full Navier–Stokes equations are solved by a parallelized finite-difference/front-tracking method that allows a deformable interface between the bubbles and the suspending fluid and the inclusion of surface tension. The Eötvös number is taken as equal to 5, so that the bubbles are ellipsoidal, and the Galileo number is 900, so that the rise Reynolds number of a single bubble in an unbounded flow is about 26. Three values of the void fraction have been investigated: 2%, 6% and 12%. At 6%, a change in the behaviour of the bubbles is observed. The bubbles are initially dispersed homogeneously throughout the flow field and their average rise Reynolds number is 23. After the bubbles have risen by about 90 bubble diameters, they form a vertical stream and accelerate. The microstructure of the bubble suspension is analysed and an explanation is proposed for the formation of these streams. The results for the ellipsoidal bubbles are compared to the results for nearly spherical bubbles, for which the Eötvös number is 1 and the Galileo number is 900. The dispersion of the bubbles and the velocity fluctuations in the liquid phase are analysed.

UAV obstacle avoidance using image processing techniques (2012)

Novel algorithms were developed for use on a low-price, consumer four-rotor helicopter with limited on-board computational capacity. Simplified occupancy grid maps, basic wall-following and obstacle avoidance were constructed from laser rangefinder data using image processing primitives in OpenCV. These algorithms generated obstacle free paths along walls in preliminary testing. The resulting system will allow untrained and unskilled users to teleoperate a low-cost flight platform, assembled from commercially available parts for remote exploration in quasi-static indoor environments.
Antigenic Relationship of Non-Serotype 1 Turkey Infectious Bursal Disease Viruses from the United States and United Kingdom (1988)

Cross-neutralization tests showed that non-serotype 1 infectious bursal disease viruses originating from turkeys in the United States and the United Kingdom belong to the same serotype. It is proposed that this serotype be designated serotype 2.
Power Efficient Trajectory Optimization for the Cellular-Connected\n Aerial Vehicles (2019)

Aerial vehicles have recently attracted significant attention in a variety of\ncommercial and civilian applications due to their high mobility, flexible\ndeployment and cost-effectiveness. To leverage these promising features, the\naerial users have to satisfy two critical requirements: First, they have to\nmaintain a reliable communication link to the ground base stations (GBSs)\nthroughout their flights, to support command and control data flows. Second,\nthe aerial vehicles have to minimize their propulsion power consumption to\nremain functional until the end of their mission. In this paper, we study the\ntrajectory optimization problem for an aerial user flying over an area\nincluding a set of GBSs. The objective of this problem is to find the\ntrajectory of the aerial user so that the total propulsion-related power\nconsumption of the aerial user is minimized while a cellular-connectivity\nconstraint is satisfied. This problem is a non-convex mixed integer non-linear\nproblem and hence, it is challenging to find the solution. To deal with, first,\nthe problem is relaxed and reformulated to a more mathematically tractable\nform. Then, using successive convex approximation (SCA) technique, an iterative\nalgorithm is proposed to convert the problem into a sequence of convex problems\nwhich can be solved efficiently.\n
[Retrocardiac pheochromocytoma associated with a double carotid site. Diagnostic and therapeutic discussion]. (1990)

A case of cardiac paraganglioma is reported in a 30 year old man operated two years previously for bilateral carotid body paraganglioma. Due to the persistence of high catecholamine levels in the superior vena cava, a cardiac localization, suspected on echocardiography, was confirmed by coronary angiography. MRI identified the exact site of the tumour in contact with the posterior surface of the left atrium and the great vessels of the base of the heart. Complete resection was performed via sternotomy. The adhesions to the great vessels and atrium and the retrocardiac site of the tumour required continuation of the operation under CPB with transection of the superior vena cava, aorta and pulmonary artery in order to achieve complete resection despite the hypervascular nature of the tumour. Postoperative collapse of peripheral resistance requiring 48 hours of adrenaline infusion demonstrated the immediate efficacy of the surgical operation. After a follow-up of four months, the blood pressure and catecholamine levels remained normal. The authors emphasise: the value of MRI for the topographic diagnosis of thoracic lesions, the association of a double carotid body paraganglioma and a mediastinal tumour, especially cardiac, which has already been reported in the literature and the availability of CPB in order to perform complete resection of these tumours with complete security in view of their intimate relations with cardiac cavities and the vessels of the base of the heart.
The role of interleukins in viral inhibition of lymphocyte mitogenesis. (1985)

Several different types of retroviruses have been shown to inhibit the lectin-driven blastogenesis of co-incubated mouse spleen cells. This abrogation of responsiveness is infection-independent, and can be obtained using live as well as UV-inactivated virus particles. Levels of both interleukin-1 (IL-1) and T-cell growth factor (TCGF) activities are greatly reduced in cultures of virus co-incubated cells. However, the inclusion of indomethacin in the culture medium, together with virus, enables responsiveness to Concanavalin A to occur at moderately efficient levels. The addition of exogenous IL-1 activity to virus co-incubated cells is also partially restorative to Con A-driven lymphocyte responsiveness, while at the same time restoring levels of detectable TCGF activity to near-control levels. Finally, the inclusion of exogenous TCGF activity also leads to efficient lymphocyte mitogenesis but does not result in increased levels of IL-1.
Shyness and Timidity in Young Adults Who Were Born at Extremely Low Birth Weight (2008)

Young adults who were born at extremely low birth weight and without major impairments are more cautious, shy, and risk aversive and less extraverted than their normal birth weight counterparts, possibly placing them at risk for future psychiatric and emotional problems.
Gallium-68 in Medical Imaging (2016)

Over the past several years, Positron Emission Tomography (PET) imaging agents labeled with ;68Gallium (68Ga) have undergone a significant increase in clinical utilization. 68Ga is conveniently produced from a germanium-68/gallium-68 (68Ge/68Ga) generator. Because of the compact size and ease of use of the generator, 68Ga labeled compounds may be more cost-effective than PET radioisotopes that are cyclotron-produced. The convenient half-life of 68Ga (T1/2=68 min) provides sufficient radioactivity for various PET imaging applications, while delivering acceptable radiation doses to patients. This chapter summarizes the emerging clinical utilization of 68Ga-based radiotracers in medical imaging.

Pasteurella multocida osteomyelitis of the cervical spine in a patient on chronic haemodialysis. (1990)

Osteomyelitis due to Pasteurella multocida has been frequently documented but virtually all previous cases have resulted from direct inoculation of the organism or contiguous spread of local infection, following animal bites or scratches. Infections often occur in patients with serious underlying illnesses. Haematogenous osteomyelitis due to P multocida has very rarely been reported particularly in patients with chronic renal failure. We describe a patient on chronic haemodialysis who developed an acute febrile illness, two months following a monkey bite, caused by haematogenous cervical vertebral osteomyelitis due to P multocida.
<title>Fabrication of high-yield Si microdiaphragms using electrochemical etch stop in TMAH/IPA/pyrazine solution</title> (1999)

This paper presents the fabrication of high-yield Si micro- diaphragms using electrochemical etch-stop method in TMAH/IPA/pyrazine solution. When IPA was added TMAH solution, the flatness of etching front is improved and undercutting is reduced, but the etch rate of (100) Si is decreased. The (100) Si etch rate is improved with addition of pyrazine. The (100) Si etch rate of 0.8/min which is faster by 13 percent than pure TMAH 20 wt percent solution is obtained using TMAH 20 wt percent/pyrazine 0.5 g and the etch rate of (100) Si is decreased with more additive quantity of pyrazine. Addition of pyrazine to TMAH 25 wt percent solution, the flatness variations of etching front is not observed and undercutting ratio is reduced about 30- 50 percent. Addition of pyrazine to TMAH increases the etch ratio f(100) Si, thus the elapsed time for etch-stop was shortened. I-V curves of n- and p-type Si in TMAH/IPA/pyrazine solution were obtained. OCP and PP of n- and p-type Si were also obtained, and applied potential was selected between n- and p-type Si's PP. 801 Si micro- diaphragms having 20 thick were fabricated on 5 inch Si wafer using electrochemical etch-stop method in TMAH/IPA/pyrazine solution. The average thicknesses of micro-diaphragms were 20.03 and standard deviation was +/- 0.26.
Capriccio (2003)

This paper presents Capriccio, a scalable thread package for use with high-concurrency servers. While recent work has advocated event-based systems, we believe that thread-based systems can provide a simpler programming model that achieves equivalent or superior performance.By implementing Capriccio as a user-level thread package, we have decoupled the thread package implementation from the underlying operating system. As a result, we can take advantage of cooperative threading, new asynchronous I/O mechanisms, and compiler support. Using this approach, we are able to provide three key features: (1) scalability to 100,000 threads, (2) efficient stack management, and (3) resource-aware scheduling.We introduce linked stack management, which minimizes the amount of wasted stack space by providing safe, small, and non-contiguous stacks that can grow or shrink at run time. A compiler analysis makes our stack implementation efficient and sound. We also present resource-aware scheduling, which allows thread scheduling and admission control to adapt to the system's current resource usage. This technique uses a blocking graph that is automatically derived from the application to describe the flow of control between blocking points in a cooperative thread package. We have applied our techniques to the Apache 2.0.44 web server, demonstrating that we can achieve high performance and scalability despite using a simple threaded programming model.
Speed optimized diode-triggered SCR (DTSCR) for RF ESD protection of ultra-sensitive IC nodes in advanced technologies (2005)

A novel diode-triggered silicon-controlled rectifier (DTSCR) (Mergens et al., 2003) electrostatic discharge (ESD) protection element is introduced for low-voltage application (signal and supply voltages /spl les/ 1.8 V) with extremely narrow ESD design margins. Trigger-voltage engineering in conjunction with fast and efficient SCR voltage clamping is applied for the protection of ultrasensitive circuit nodes, such as SiGe heterojunction bipolar transistor (HBT) base regions (e.g., f/sub Tmax/=45 GHz in BiCMOS 0.35-/spl mu/m LNA input) and thin gate oxides (e.g., t/sub ox/=1.7 nm in CMOS 0.09-/spl mu/m high-speed input). Ultrathin gate protection requires a reinforced trigger diode chain to avoid SCR trigger-speed issues resulting in critical trigger-voltage overshoots for very fast ESD transients such as a charged device model (CDM). SCR integration can be realized based on parasitic n-p-n/p-n-p inherent to CMOS devices or can alternatively be implemented based on vertical high-speed SiGe HBT with adjacent p+ SCR anode.
