MIMO radar demystified and where it makes sense to use (2014)

Contrary to claims made Multiple Input and Multiple Output (MIMO) radars do not provide an order of magnitude or better angle resolution, accuracy and identifiability (the ability to resolve and identify targets) over conventional radars. This claim is based on using a MIMO array radar system consisting of a full transmit array and thinned receive array (or vice versa; called here a full/thin array). This claim for MIMO results from making the wrong comparison to a full conventional array rather than to a conventional full/thin array. It is shown here that a conventional full/thin array radar can have the same angle accuracy, resolution and identifiability as a MIMO full/thin array. Where does the MIMO radar provide a better angle accuracy than a conventional radar? A monostatic MIMO array radar does provide a better angle accuracy than its conventional monostatic equivalent, but it is only about a factor of 1/√2 (29 percent) better and its resolution is the same.
Variations on a Method for Representing Data Items of Unlimited Length (1985)

A recent encoding method [11 is revisited here, and two simple variations are proposed to reduce the length of the encoded data strings. The new variations also decrease encoding time, and allow numerical data to be represented in any base.
Evaluation of slipperiness of catheter surfaces (1996)

A test method is described that allows the characterization of the subjective feeling of lubricity of catheter surfaces in a quantitative way. The test consists in pulling out, by a weight, a catheter tubing from a test tube filled with agar. Results show that the surface of a polyurethane catheter tubing coated with the hydrophilic poly (hydroxyethylmethacrylate) is readily hydrated by the water contained in the agar. The hydrogel coated tubing slides very quickly, due to the lubricating surface layer of water. The untreated polyurethane tubing and the same tubing after plasma treatment were definitely less slippery than the poly (hydroxyethylmethacrylate) coated ones. Atomic force microscopy was used to evaluate the contribution of the surface morphology of the samples to the obtained results.
Lithium-Ion Batteries: Modelling and State of Charge Estimation (2013)

Lithium-ion (Li-ion) cells are increasingly used in many applications affecting our daily life, such as laptops computers, cell phones, digital cameras, and other portable electronic devices. Lithium-ion batteries are increasingly being considered for their use in Electric Vehicles (EV), Hybrid Electric Vehicles (HEV) and Plug-in Hybrid Electric Vehicles (PHEV) due to their high energy density, slow loss of charge when not in use, and for lack of hysteresis effect. New application domains for these batteries has placed greater emphasis on their energy management, monitoring and control strategies. In this thesis, a comparative study between different models and state of charge (SOC) estimation strategies is performed. Battery models range from black-box representation to detailed electrochemical reaction models that consider the underlying physics. The state of charge is estimated using the Extended Kalman filter (EKF) and the Smooth Variable Structure Filter (SVSF). The models and SOC estimation strategies are applied to experimental results from BMW Electrical and Hybrid Research and Development center and validated using a simulation model from AVL CRUISE software. Overall, different models and SOC estimation scenarios were studied. An average improvement of 30% in the estimation accuracy was shown by the SVSF SOC method when compared with the EKF SOC strategy. In general, the SVSF SOC estimation technique demonstrates excellent capability and a fast speed of convergence.

Liquid Crystalline Networks toward Regenerative Medicine and Tissue Repair (2017)

The communication reports the use of liquid crystalline networks (LCNs) for engineering tissue cultures with human cells. Their ability as cell scaffolds for different cell lines is demonstrated. Preliminary assessments of the material biocompatibility are performed on human dermal fibroblasts and murine muscle cells (C2C12), demonstrating that coatings or other treatments are not needed to use the acrylate-based materials as support. Moreover, it is found that adherent C2C12 cells undergo differentiation, forming multinucleated myotubes, which show the typical elongated shape, and contain bundles of stress fibers. Once biocompatibility is demonstrated, the same LCN films are used as a substrate for culturing human induced pluripotent stem cell-derived cardiomyocites (hiPSC-CMs) proving that LCNs are capable to develop adult-like dimensions and a more mature cell function in a short period of culture in respect to standard supports. The demonstrated biocompatibility together with the extraordinary features of LCNs opens to preparation of complex cell scaffolds, both patterned and stimulated, for dynamic cell culturing. The ability of these materials to improve cell maturation and differentiation will be developed toward engineered heart and skeletal muscular tissues exploring regenerative medicine toward bioartificial muscles for injured sites replacement.
Development of a multifunctional robot end- effector system for automated manufacture of textile preforms (2007)

In addition to the well-known application fields of composite materials in the aircraft industry, sport cars and wind energy, there are further potential applications e.g. rail, automobile and machine construct. In contrast to dry technology (prepreg), wet technology using reinforced textile preforms offers a cost-effective production of composite structures. These are due to low cost materials, easier storage conditions and automation possibilities. In this work, a new multifunctional robot end-effector system for automated manufacture of textile preforms is developed, designed and implemented. The robot end-effector system consists of an adaptive end-effector (AEE) to grasp, manipulate and lay-up the composite fabric onto a flat or curved mold and a novel double tool changer (DTC) to drape the fabric in the mold. The AEE is modular designed and features local passive and active degrees of freedom (DOF) to adapt the fabric geometry to the mold geometry. Furthermore, it is integrated with eight gripper elements with different grasp principles, such as ice-gripper or needle-gripper. Robots using DTC can carry two small tools (in this case two rollers to drape the fabric) and interchange them in the working position. With AEE and DTC, many manual processes in the production chain of textile preforms can be automated and can also be applied to the cost-efficient production of fibre composite parts. The application of this robot end-effector will be demonstrated by the production of a convertible car roof (CCR) with a pilot plant.

Investigation of submarine groundwater discharge (2002)

Abstract Coastal hydrogeologists and oceanographers now recognize the potentially significant contribution that submarine groundwater discharge (SGD) could make to the coastal ocean. SGD may be both volumetrically and chemically important to coastal water and chemical budgets. A worldwide compilation of observed SGD shows that groundwater seepage from the land to the ocean occurs in many environments along the world's continental margins. Further, SGD has a significant influence on the environmental condition of many nearshore marine environments and provides a strong motivation for improved assessments. Our review reveals a critical lack of data from coastal zones of almost all parts of the world, especially in South America, Africa and parts of Asia, making a comprehensive compilation incomplete. SGD should be paid more attention with regard to water and dissolved material budgets at the local and global scales. SGD intercomparison experiments and coastal typologies (classification) may enable evaluation of the accuracy of the SGD estimates and up‐scaling of SGD to a global scale.

Pramlintide acetate in the treatment of Type 2 and Type 1 diabetes mellitus (2006)

Maintenance of glucose homeostasis involves the interplay of multiple glucoregulatory factors, including the pancreatic β-cell hormones insulin and amylin. Amylin, a neuroendocrine hormone, is secreted in response to nutrient intake and suppresses postprandial glucagon secretion, helps regulate gastric emptying, and reduces food intake. Patients with diabetes are deficient in both insulin and amylin - contributing to postprandial hyperglycemia. Pramlintide, an analogue of amylin, is the active ingredient in the SYMLIN<sup>®</sup> (pramlintide acetate) injection. SYMLIN is indicated as an adjunctive treatment for insulin-using patients with diabetes and works through mechanisms similar to those of amylin. Clinical trials have demonstrated that pramlintide therapy improves postprandial glucose control, lowers A1C, and is accompanied by a reduction in body weight. Mild-to-moderate nausea and an increased risk of insulin-induced severe hypoglycemia have been the most common side effects. These side effects can be mitigated by gradual pramlintide dose escalation during treatment initiation and proactive mealtime insulin dose reduction upon initiation of pramlintide therapy.
Efficacy of Antibiotic-Coated Catheters in Preventing Subcutaneous Staphylococcus aureus Infection in Rabbits (1993)

Vascular catheters coated with antiinfective compounds were evaluated as to their ability to prevent Staphylococcus aureus catheter infection in a rabbit model. Zones of inhibition of agar surface-plated S. aureus demonstrated the following hierarchy: dicloxacillin and clindamycin were each better than fusidic acid or chlorhexidine, which were better than ciprofloxacin, cefotaxime, or cefuroxime. In vivo half-lives of inhibitory activity for clindamycin and dicloxacillin were 5.6 and 17.7 h, respectively, with apparent first-order kinetics. Chlorhexidine disappeared in vivo with apparent two-compartment kinetics: first-compartment t1/2, 16.8 h; second-compartment t1/2, 115.6 h. In a rabbit model, dicloxacillin, clindamycin, fusidic acid, and chlorhexidine decreased the risk of infection compared with uncoated control catheters (P < .05). For dicloxacillin, clindamycin, and chlorhexidine, this was true even if the S. aureus inoculation was delayed 48 or 96 h after catheter implantation. These data suggest that vascular catheters with antiinfective coatings should be investigated further in hospitalized patients.
Avian Persistence in Fragmented Rainforest (2002)

What factors determine the persistence of species in fragmented habitats? To address this question, we studied the relative impacts of forest deterioration and fragmentation on bird species in 12 rainforest fragments in Kenya, combining 6 years of individual capture-recapture data with measurements of current captures and museum specimens. Species mobility, as estimated from species-specific dispersal rates, and tolerance to habitat deterioration, as estimated from change in fluctuating asymmetry with increasing habitat disturbance, explained 88% of the variation in patch occupancy among eight forest bird species. Occupancy increased with mobility and with tolerance to deterioration, where both variables contributed equally to this relationship. We conclude that individual-level study, such as of dispersal behavior and phenotypic development, can predict patterns of persistence at the species level. More generally, for conservation tactics to stand a high chance of success, they should include action both within sites, to minimize habitat deterioration, and across landscapes, to maximize dispersal.
Abnormalities in osteoclast precursors and marrow accessory cells in Paget's disease. (1993)

Paget's disease of bone is characterized by increased numbers of abnormal osteoclasts. To determine if osteoclast precursors were increased or abnormal in this disease, we examined CFU-GM, the committed granulocyte-macrophage progenitor and the most likely precursor for osteoclasts. In cultures of unfractionated marrow mononuclear cells, CFU-GM colony formation was significantly increased in Paget's marrow cultures compared to that in normal cells (356 +/- 44 vs. 271 +/- 15/10(5) cells; P < 0.05). However, when we enriched hematopoietic precursors from Paget's and normal marrow samples using an antibody that recognizes the CD34 antigen present on most hematopoietic precursors, we found that similar numbers of CFU-GM colonies were formed (87 +/- 13/10(4) cells plated vs. 83 +/- 13). Coculture experiments with highly purified hematopoietic precursors (CD34+ cells) and nonhematopoietic marrow accessory cells (CD34- cells) revealed that the growth of Paget's precursors was significantly enhanced above expected levels by normal or Pagetic CD34- cells (P < 0.05). CFU-GM colony formation was also significantly enhanced when normal CD34+ cells were cocultured with Pagetic, but not with normal, CD34- cells. In addition, CFU-GM colony-derived cells from Paget's patients were hyperresponsive to 1,25-dihydroxyvitamin D3 and could form osteoclast-like multinucleated cells with 1,25-dihydroxyvitamin D3 concentrations one tenth of that required for normal multinucleated formation (10(-11) vs. 10(-10) M). These data suggest that osteoclast precursors may be abnormal in Paget's disease, and other cells in the Pagetic marrow microenvironment may further enhance the growth and differentiation of these abnormal precursors.
New Traffic Signal Controller for Improved Fail-Safe Functions (2014)

For the safe and smooth travel of vehicles, motor bikes, bicycles, and pedestrians on the road, traffic signal controllers (TSC) turn traffic lights on and off and manage their durations. Erroneous control of traffic lights can easily lead to serious accidents. This is why a TSC in particular requires the strictest fail-safe functions among the variety of devices used in each traffic control system. We have developed a new TSC, with improved architecture and failsafe functions compared with the previous model. This paper discusses the fail-safe functionality improvements in the new TSC.
Efficient algorithms for distributed query processing in star and extended-star networks (2003)

Scheduling algorithms for processing queries in a star or extended-star network are presented. A relational database system is assumed, and the data transmission time for joins of attributes is the dominating factor in the query processing. The first algorithm STAR-RT for minimizing the response time of a star query is based on the principle of dynamic programming. The second one, STAR-CT, is an approximation algorithm also for processing a star query, but it aims at minimization of the total communication time. Two optimization subproblems are derived in connection with the query processing and STAR-CT is based on the strategies for solving these subproblems. The above algorithms are extended to those for more general query processing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Complete Genome Sequence of the Lactic Acid Bacterium <i>Lactococcus lactis</i> ssp. <i>lactis</i> IL1403 (2001)

Lactococcus lactis is a nonpathogenic AT-rich gram-positive bacterium closely related to the genus Streptococcus and is the most commonly used cheese starter. It is also the best-characterized lactic acid bacterium. We sequenced the genome of the laboratory strain IL1403, using a novel two-step strategy that comprises diagnostic sequencing of the entire genome and a shotgun polishing step. The genome contains 2,365,589 base pairs and encodes 2310 proteins, including 293 protein-coding genes belonging to six prophages and 43 insertion sequence (IS) elements. Nonrandom distribution of IS elements indicates that the chromosome of the sequenced strain may be a product of recent recombination between two closely related genomes. A complete set of late competence genes is present, indicating the ability of L. lactis to undergo DNA transformation. Genomic sequence revealed new possibilities for fermentation pathways and for aerobic respiration. It also indicated a horizontal transfer of genetic information from Lactococcus to gram-negative enteric bacteria of Salmonella-Escherichia group.

Effects of atrasentan on disease progression and biological markers in men with metastatic hormone-refractory prostate cancer: Phase 3 study (2004)

4508 Background: In earlier trials, atrasentan, a potent, selective, oral endothelin A receptor antagonist, significantly delays time to disease progression (TTP) in a per-protocol group of hormone-refractory prostate cancer (HRPC) patients identified pre–blind break. We report the results from a phase 3 trial. Methods: 809 subjects with metastatic HRPC enrolled into a phase 3, randomized, double-blind, placebo-controlled study of 10 mg atrasentan were analyzed (401 placebo, 408 atrasentan). Kaplan-Meier and Cox proportional hazard methodologies were used to compare TTP (a composite of radiographic and clinical measures) between treatments. Analysis of covariance compared change from baseline to final value in PSA and bone and total alkaline phosphatase (BAP and ALP). Data from a protocol-compliant subset identified prior to blind break were analyzed as well. Results: Atrasentan exhibited a nonsignificant trend in delayed TTP (log-rank p=0.091; hazard ratio [HR] = 1.14, 95% CI = 0.98–1.34) and significantly delayed time to BAP progression (TTBAP, >50% increase from nadir) versus placebo (median: 254 vs 505 days; log-rank p<0.001; HR = 1.78, 95% CI = 1.34–2.37). The atrasentan group showed smaller mean increases than the placebo group in PSA (p=0.025), BAP (p=0.001), and ALP (p<0.001). In the protocol-compliant subset (329 placebo, 342 atrasentan), atrasentan significantly delayed TTP (log-rank p=0.007; HR = 1.26, 95% CI = 1.06–1.50) and TTBAP (log-rank p<0.001) and resulted in smaller mean changes from baseline to final in the 3 biological markers. Atrasentan was well tolerated. The most common associated adverse events, peripheral edema, rhinitis, and headache, resulted in few discontinuations. Conclusions: Atrasentan demonstrated a significant delay in TTP and attenuated increase in relevant bone and tumor markers in metastatic HRPC patients representative of the intended target population. The accumulating and consistent data for atrasentan demonstrates biologic and clinical activity of endothelin receptor blockade in metastatic HRPC.

Viruses associated with outbreaks of equine respiratory disease in New Zealand (2002)

Of the equine respiratory viruses detected in horses in New Zealand during this study, EHV-2 was most likely to be associated with respiratory disease. However, factors other than viral infection are probably important in the development of clinical signs of disease.

We present an improved calculation of $B\ensuremath{\rightarrow}$ light pseudoscalar form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading-order twist-4 corrections. The total theoretical uncertainty of our results at zero momentum transfer is 10 to 13% and can be improved, at least in part, by reducing the uncertainty of hadronic input parameters, in particular, those describing the twist-2 distribution amplitudes of the $\ensuremath{\pi}$, $K$, and $\ensuremath{\eta}$. We present our results in a way which details the dependence of the form factors on these parameters and facilitates the incorporation of future updates of their values from, e.g., lattice calculations.
Chirality and circular dichroism of oriented molecules and anisotropic phases (2000)

The results of the “Chirality measurement” circular dichroism along different viewing directions within molecules and phases—the anisotropy of circular dichroism can give suitable information in order to check helicity rules or to analyze the suprastructural chirality of films of organic materials, respectively. These results of the ACD spectroscopy (the CD of anisotropic phases and oriented molecules) show that in an oriented state different information about “chirality” will be gained from different viewing directions. ACD measurements of α,β-unsaturated ketosteroids, TADDOLes and binaphthol derivatives were analyzed. The chiral induction of cholesteric phases, the helical twisting power, is introduced as another chirality measurement which may possibly be a new relative method for the determination of the absolute configuration.
