[POSTER] Exploiting Photogrammetric Targets for Industrial AR

In this work, we encourage the idea of using Photogrammetric targets for object tracking in Industrial Augmented Reality (IAR). Photogrammetric targets, especially uncoded circular targets, are widely used in the industry to perform 3D surface measurements. Therefore, an AR solution based on the uncoded circular targets can improve the work flow integration by reusing existing targets and saving time. These circular targets do not have coded patterns to establish unique 2D-3D correspondences between the targets on the model and their image projections. We solve this particular problem of 2D-3D correspondence of non-coplanar circular targets from a single image. We introduce a Conic pair descriptor, which computes the Eucledian invariants from circular targets in the model space and in the image space. A three stage method is used to compare the descriptors and compute the correspondences with up to 100% precision and 89% recall rates. We are able to achieve tracking performance of 3 FPS (2560x1920 pix) to 8 FPS (640×480 pix) depending on the camera resolution and the targets present in the scene.
Micellar structure changes in aqueous mixtures of nonionic surfactants

Rheology and small-angle neutron scattering are used to probe the structure of nonionic surfactant mixtures in water. Small amounts of a C14 diol (Surfynol® 104) cause enormous structural and rheological changes when added to aqueous solutions of an ethylene oxide-propylene oxide-ethylene oxide triblock copolymer (Pluronic® P105). The C14 diol is only soluble up to 0.1 wt % in pure water, but can be added in large quantities to aqueous solutions of the copolymer. The hydrophobic diol incorporates into the existing copolymer micelles and causes a cascade of changes in the micelle structure, with resultant changes in rheology. Particularly striking is the spherical to worm-like micelle transition, where the viscosity changes by a factor of more than 104.
Virus clearance and immunopathology by CD8+ T cells during infection with respiratory syncytial virus are mediated by IFN‐γ 

CD8+ T cells (CTL) are important effector cells for virus control and immunopathology after primary infection with respiratory syncytial virus (RSV). To investigate the effector mechanisms involved, we set up an adoptive transfer model, in which effector CTL specific for p82–90 of RSV M2 were generated in vivo, followed by short‐term restimulation in vitro and transfusion into infected recipients. A total of 4×104 donor‐derived p82‐specific CTL homing to the lung within 4 days after transfusion were sufficient to completely eliminate a virusinoculum of 1.5×106 pfu. This was accompanied by significant lung pathology. Surprisingly, virus control and immunopathology proceeded unimpaired when donor cells lacking perforin, CD95 ligand or TNF were transfused. By contrast, treatment of recipient mice with a neutralizing antibody against IFN‐γ or transfusion of IFN‐γ‐deficient effector CTL largely abolished virus control and significantly reduced CD8+ T cell‐mediated pathology. In IFN‐γ‐deficient mice, high‐dose primary infection experiments revealed attenuated immunopathology, but only slightly delayedvirus clearance, suggesting that other cells and molecules can partly substitute for the effects of CTL‐derived IFN‐γ on virus clearance. These experiments identify IFN‐γ as a key molecule in RSV‐induced immunopathology and in CD8+ T cell‐mediated control of RSV infection.
Impressionism in Cloud Computing - A Position Paper on Capacity Planning in Cloud Computing Environments

Cloud computing is a model that relies on virtualization and can lower costs to the user by charging only for the computational resources used by the application. There is a way to use the advantages of cloud computing in data-intensive applications like MapReduce and it is by using a virtual machine (VM) cluster in the cloud. An interesting challenge with VM clusters is determining the size of the VMs that will compose the cluster, because with an appropriate cluster and VM size, users will be able to take a full advantage of resources, i.e., reducing costs by using idle resources and gaining performance. This position paper is intended to bring to consideration the necessity for accurate capacity planning at user level, in order to take fully advantage of cloud resources and will focus specially for data-intensive applications users.
Papillary‐cystic neoplasm of the pancreas. Report of two cases and review of the literature

Two cases of papillary‐cystic neoplasm of the pancreas are reported in women aged 22 and 23 years. The patient in the first case presented with acute abdominal pain and hemoperitoneum. This form of presentation has not been previously reported. This type of pancreatic tumor is very rare, exclusively affecting young women, and has a good prognosis despite its various histologic features, which suggest a malignant appearance. The authors consider this neoplasm as having an acinar origin because in the cells of one of the patients we observed ultrastructurally the presence of abundant rough endoplasmatic reticulum with formation of annulate lamellae and a few prezymogen granules.

Biofeedback is an effective treatment for patients with dyssynergic defaecation.

INTRODUCTION Constipation is a common affliction affecting the general population, with dyssynergic defaecation accounting for a large proportion of tertiary referrals. We sought to review the results of our patients with dyssynergic defaecation treated with biofeedback therapy in order to determine its efficacy. METHODS All patients who were referred to the anorectal physiology laboratory of our tertiary unit for biofeedback therapy for dyssynergic defaecation were reviewed. Patients diagnosed with secondary constipation and slow-transit constipation were excluded. A defaecating proctogram was used to exclude anatomical abnormalities causing outlet obstruction. Patients underwent a four-session, structured biofeedback exercise programme under the supervision of trained nurses. The effectiveness of biofeedback treatment was assessed using the validated Eypasch's Gastrointestinal Quality of Life Index (GIQLI). RESULTS 226 patients (85 male, 141 female; median age 48 years) underwent biofeedback treatment. Post treatment, improvement was observed in the overall total score of the GIQLI, with gastrointestinal symptom (68.6%), emotion (61.0%) and physical function (57.9%) components showing the most improvement. These improvements were also reflected in the mean scores of each component and the mean total score. All components, except for social function and medication, and the overall total score showed significant improvement post treatment. At the one-year follow-up, 160 (71%) patients reported that improvements were maintained. CONCLUSION Biofeedback is an effective treatment for patients with dyssynergic defaecation. Patients with chronic constipation not improved by fibre and laxatives should be referred to a tertiary centre with facilities for further anorectal physiological assessment.
Three-dimensional polycaprolactone–hydroxyapatite scaffolds combined with bone marrow cells for cartilage tissue engineering

The goal of this study was to investigate the chondrogenic potential of three-dimensional polycaprolactone–hydroxyapatite (PCL–HA) scaffolds loaded with bone marrow cells in vitro and the effect of PCL–HA scaffolds on osteochondral repair in vivo. Here, bone marrow was added to the prepared PCL–HA scaffolds and cultured in chondrogenic medium for 10 weeks. Osteochondral defects were created in the trochlear groove of 29 knees in 17 New Zealand white rabbits, which were then divided into four groups that underwent: implantation of PCL–HA scaffolds (left knee, n = 17; Group 1), microfracture (right knee, n = 6; Group 2), autologous osteochondral transplantation (right knee, n = 6; Group 3), and no treatment (right knee, n = 5; Control). Extracellular matrix produced by bone marrow cells covered the surface and filled the pores of PCL–HA scaffolds after 10 weeks in culture. Moreover, many cell-laden cartilage lacunae were observed, and cartilage matrix was concentrated in the PCL–HA scaffolds. After a 12-week repair period, Group 1 showed excellent vertical and lateral integration with host bone, but incomplete cartilage regeneration and matrix accumulation. An uneven surface of regenerated cartilage and reduced distribution of cartilage matrix were observed in Group 2. In addition, abnormal bone growth and unstable integration between repaired and host tissues were detected. For Group 3, the integration between transplanted and host cartilage was interrupted. Our findings indicate that the PCL–HA scaffolds loaded with bone marrow cells improved chondrogenesis in vitro and implantation of PCL–HA scaffolds for osteochondral repairenhanced integration with host bone. However, cartilage regeneration remained unsatisfactory. The addition of trophic factors or the use of precultured cell–PCL–HA constructs for accelerated osteochondral repair requires further investigation.
Lung function and bronchial responsiveness in children who had infantile bronchiolitis

A number of studies have shown that children who had infantile bronchiolitis are at increased risk of recurrent episodes of wheezing. A genetic predisposition to atopy is mentioned in some studies and is contested by others. Lung function abnormalities and increased bronchial responsiveness (BR) have been described after infantile bronchiolitis. We investigated children who had had the clinical syndrome of bronchiolitis during infancy and compared them with asthmatic and healthy children of the same age regarding bronchial caliber, smooth muscle tone, and responsiveness to histamine. Lung function was measured by forced oscillometry. We found that most children with current symptoms had either decreased baseline bronchial caliber, increased bronchial smooth muscle tone, or increased BR. These patients are comparable to mild asthmatics. The children without current symptoms are comparable to healthy children in these respects. Recurrent respiratory symptoms after bronchiolitis should be regarded as mild asthma and treated as such. Pediatr Pulmonol 1987; 3; 38–44.
The janus faces of botulinum neurotoxin: Sensational medicine and deadly biological weapon

The botulinum neurotoxins are the most dangerous toxins known (BoNTs serotypes A–G) and induce profound flaccid neuromuscular paralysis by blocking nerve–muscle communication. Poisoned motoneurons react by emitting a sprouting network known to establish novel functional synapses with the abutting muscle fiber. Understanding how our motoneurons are capable of bypassing such transmission blockade, thereby overcoming paralysis, by an astonishing display of plasticity is one of the research goals that have numerous therapeutic ramifications. This Mini‐Review aims at giving a brief update on the recent discoveries regarding the molecular mechanism of botulinum toxins intoxication. Curing botulism still is a challenge once the toxin has found his way inside motoneurons. In view of the potential use of botulinum toxins as biological weapon, more research is needed to find efficient ways of curing this disease. © 2007 Wiley‐Liss, Inc.
Effects of various beverages on hardness, roughness, and solubility of esthetic restorative materials.

STATEMENT OF THE PROBLEM Restorative materials may either be exposed intermittently or continuously to chemical agents found in beverages, which may lead to biodegradation. PURPOSE This study was aimed to evaluate effects of various beverages on microhardness, surface roughness, and solubility of esthetic restorative materials. MATERIALS AND METHODS Materials used were conventional glass ionomer, resin-modified glass ionomer, compomer, and composite resin. Microhardness of the restorative materials was measured using Vickers microhardness tester. Surface roughness was measured using surface profilometery. Solubility was measured using an electronic balance. RESULTS In general, low pH beverages adversely affected the properties of the tested materials. Microhardness of tested materials was significantly decreased after immersion in the various beverages, whereas surface roughness and solubility were increased with the exception of natural milk. Natural milk and water did not affect the tested materials as Mirinda orange or mango juice did. Microhardness, roughness, and solubility of the tested materials in water were comparable with those of natural milk. After the immersion period, the conventional glass ionomer showed the roughest surface and exhibited the highest solubility, whereas composite resin was the smoothest surface and the lowest solubility. There was a negative correlation between surface roughness and microhardness, as well as between solubility and microhardness. There was a positive correlation between surface roughness and solubility. CONCLUSIONS Low pH beverages were the most aggressive media for glass ionomers and compomer, by contrast, composite resin was relatively less affected. Water and natural milk appeared relatively benign towards the tested materials.
EXPLORATORY CHANDRA OBSERVATION OF THE ULTRALUMINOUS QUASAR SDSS J010013.02+280225.8 AT REDSHIFT 6.30

We report exploratory Chandra observations of the ultraluminous quasar SDSS J010013.02+280225.8 at redshift 6.30. The quasar is clearly detected by Chandra with a possible component of extended emission. The rest-frame 2–10 keV luminosity is 9.0 − 4.5 + 9.1 × 1045 erg s−1 with an inferred photon index of Γ = 3.03 − 0.70 + 0.78 . This quasar is X-ray bright, with an inferred X-ray-to-optical flux ratio α ox = − 1.22 − 0.05 + 0.07 , higher than the values found in other quasars of comparable ultraviolet luminosity. The properties inferred from this exploratory observation indicate that this ultraluminous quasar might be growing with super-Eddington accretion and probably viewed with a small inclination angle. Deep X-ray observations will help to probe the plausible extended emission and better constrain the spectral features for this ultraluminous quasar.
Atelocollagen Sponge and Recombinant Basic Fibroblast Growth Factor Combination Therapy for Resistant Wounds with Deep Cavities

Recent advances in bioengineering have introduced materials that enhance wound healing. Even with such new tools, some deep ulcers surrounded by avascular tissues, including bone, tendon, and fascia, are resistant to various therapies and easily form deep cavities with loss of subcutaneous tissue. Atelocollagen sponges have been used as an artificial dermis to cover full‐thickness skin defects. Topical recombinant human basic fibroblast growth factor has been introduced as a growth factor to induce fibroblast proliferation in skin ulcers. We applied these materials in combination in two patients with deep resistant wounds: one with a cavity reaching the mediastinum through a divided sternum and one with deep necrotic wounds caused by electric burns. These wounds did not respond to the topical basic fibroblast growth factor alone. In contrast, the combination therapy closed the wounds rapidly without further surgical treatment. This combination therapy is a potent treatment for resistant wounds with deep cavities.
Pharmacological action of breakdown products of atracurium and related substances.

The neuromuscular and cardiovascular effects of the breakdown products of atracurium and related substances have been studied in cats anaesthetized with chloralose. Laudanosine, the quaternary acid and metholaudanosine had no neuromuscular blocking activity within the dose range 0.5-4 mg kg-1. However, the quaternary monoacrylate, the quaternary alcohol and the monoquaternary analogue produced a dose-dependent neuromuscular block within this dose range. At 4 mg kg-1 mean arterial pressure was significantly reduced by 30-70 mm Hg following the administration of the quaternary monoacrylate, laudanosine, the quaternary alcohol, metholaudanosine and the monoquaternary analogue. At this dose only the monoquaternary analogue caused significant sympathetic blockade after preganglionic nerve stimulation. Significant vagal blockade occurred after 4 mg kg-1 of the quaternary monoacrylate, the quaternary acid, the quaternary alcohol and the monoquaternary analogue. In view of the low potencies of these substances, it is likely that the quantities present either as an impurity or likely to be formed after administration of therapeutic doses of atracurium (0.3-0.6 mg kg-1 i.v.) are of no pharmacological importance.
Driver Topologies for RF Doherty Power Amplifiers

In this letter, class-B, embedded class-B, and Doherty driver topologies are investigated for RF Doherty Power Amplifiers (PAs). The investigation is firstly conducted theoretically and by simulations and then verified by design and implementation of the different topologies at 2.1 GHz using GaN-HEMT transistors. The results show that the highest lineup efficiency can be achieved when using a Doherty driver. Modulated measurements using the same LTE signal and the same digital per-distorter (DPD), show about 2% and 4% higher average lineup efficiency when the Doherty driver is used compared to the class-B and embedded class-B drivers, respectively.
Influence of bank vegetation on channel morphology in rural and urban watersheds

Stream-bank vegetation significantly influences the morphology of streams in the Piedmont region of the United States. We surveyed the morphology of 26 paired stream reaches in southeastern Pennsylvania, northern Maryland, and Delaware. One member of each pair has a forested riparian zone, whereas the other has a riparian zone composed pri marily of grass. The paired reaches are nearly contiguous, so all significant channel-forming variables except riparian vegetation are held constant. The extent of urban development of the watersheds upstream of the paired reaches also varies considerably, allowing us to determine the combined influence of riparian vegetation and urbanization on channel morphology. Statistical analyses indicate that (1) channels with forested riparian zones are wider than channels with nonforested riparian zones, (2) channels in urbanized watersheds are wider than channels in nonurbanized watersheds, and (3) the effect of riparian vegetation is independent of the level of urbanization.
Rear-End Collision detection based on GNSS/compass fusion and adaptive neuro fuzzy inference system

Rear-End Collision has been considered as one of the most frequent accidents on roadways. In recent years, Global Satellite Navigation System (GNSS) with the merit of flexible and low cost, has exhibited the great potential for the rear-end Collision Avoidance Systems (CAS) for vehicles. Nevertheless, two main issues associated with the current rear-end CAS are: 1) accessing to high accuracy vehicle relative positioning and dynamic parameters; and 2) the reliable method to extract the car-following status from such information. This paper has developed a novel GNSS/compass fusion with the Adaptive Neuro Fuzzy Inference System (ANFIS) based algorithm for the real-time car-following status identification. The initial field test results have demonstrated the effectiveness of the proposed algorithms with the false alarm of 7.25% in the 10Hz output rate.
Mitogen-activated Protein Kinases in Rat Brain Neuronal Cultures Are Activated by Angiotensin II Type 1 Receptors and Inhibited by Angiotensin II Type 2 Receptors*

Neurons cultured from neonatal rat hypothalamus and brainstem contain many angiotensin II (Ang II) type 2 (AT2) receptors, and we previously determined that activation of these sites elicited a stimulation of serine/threonine phosphatase 2A (PP2A). Here, we have investigated the effects of Ang II on neuronal mitogen-activated protein (MAP) kinases, potential targets for PP2A. Using in-gel kinase assays and immunoprecipitation analyses we have shown that Ang II (10 nM-1 μM) elicits significant increases in p44MAPK (Erk1) and p42MAPK (Erk2) activities in cultured neurons, mediated via Ang II type 1 (AT1) receptors. This stimulatory effect of Ang II on Erk1 and Erk2 activities was potentiated by blockade of AT2 receptors with (S)-1-[4-(dimethylamino)-3-methylphenyl]methyl-5-(diphenylacetyl)-4,5,6,7-tetrahydro-1H-imidazo[4,5-C]pyridine-6-carboxylic acid (PD 123319, 1 μM). Furthermore, the AT2 receptor agonist N-α-nicotinoyl-Tyr-Lys-(N-αCBZ-Arg)-His-Pro-Ile-OH (CGP42112A) (10–50 nM) caused significant decreases in neuronal Erk1 and Erk2 activities, which were abolished by PD 123319 (1 μM) and by the PP2A inhibitor okadaic acid (3 nM). This indicates that AT1 and AT2 receptors have opposite actions on Erk1 and Erk2 activities in neonatal neurons. Since MAP kinases are involved in the regulation of growth/differentiation and apoptosis, our data may provide an intracellular basis for modulatory effects of Ang II receptors on these processes.
Long Life-Time Amorphous-InGaZnO TFT-Based Shift Register Using a Reset Clock Signal

We report a long life-time shift register (SR) made of amorphous-indium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs). The life-time of an SR is determined by the stability of the pull-down TFT, which is always under positive bias stress (PBS). To compensate for the nonrecovering characteristic of a-IGZO TFTs, the gate ON time of the pull-down TFT is reduced from 50% to 5% duty ratio by introducing a reset clock signal. By fitting the TFT's PBS-induced threshold voltage shifts to stretched exponentials, the life-time of the SR is estimated to increase from 1.7 to 17.5 years, owing to the reset clock signal with short-term duty.
EFFECTS OF PHYTASE INCLUSION TO DIETS WITH REDUCED AVAILABLE PHOSPHORUS CONTENT ON BROILER PERFORMANCE

An experiment was conducted to determine the effects of phytase supplementation to diets with modified available phosphorus (AP) contents relative to NRC requirements on performance and carcass traits of broilers. Ten dietary treatments consisted of: a control (NRC AP), and 9 diets combining phytase levels of 300, 600, and 900 FTU/kg and reduction of AP (RAP) by 0.05, 0.10, and 0.15% below NRC requirements in each of the three growth phases. Six hundred chicks were assigned to 40 floor pens with four replicate pens per treatment. Bodyweight (BW), feed intake (FI), BW gain (BWG), and feed conversion (FC) was determined. At 49 d, a total of 200 birds were processed and carcass traits recorded. No significant differences in FI and BWG were observed among treatments at any age, nor were differences in BW in the starter and finisher phases. However, in the growing period birds fed diets containing a 0.05% RAP and 300 FTU/kg were significantly heavier than birds fed diets with 300 and 600 FTU/kg and 0.15 and 0.10% RAP, respectively. From 22 to 35 d, broilers fed diets with of 0.05 and 0.10% RAP and 600 FTU/kg had significantly better FC than controls. , whereas from 36 to 49 d, birds receiving diets with a 0.10% RAP and 900 FTU/kg had better FC than controls. No differences among treatments were observed in the weight and yield of major cuts and excised muscles. Carcass yield (CY) was significantly higher in birds fed diets with a 0.10% RAP and 600 FTU/kg than those under the 0.15% RAP and 300 FTU/kg treatment.
