The Wearable Artificial Endocrine Pancreas with a Needle‐ Type Glucose Sensor: Perfect Glycemic Control in Ambulatory Diabetics (1984)

Abstract We have succeeded in miniaturizing a glucose monitoring system into a needle type which preserves the characteristics suitable to apply in a wearable closed‐loop control system. The wearable artificial endocrine pancreas (12 times 15 times 6 cm, 400 g) consists of the sensor, a microcomputer system which calculates insulin and glucagon infusion rates and a 2‐syringe driving system. When glucose monitorings were attempted by a needle‐type glucose sensor inserted in subcutaneous tissue of the forearm or abdomen of healthy and diabetic volunteers, these results were around 10% lower than blood glucose concentrations, but high correlation between them was observed in the range of49–388 mg/dl. Perfect glycemic controls were established by infusing insulin intravenously or even subcutaneously in response to measured glucose concentrations on a moment‐to‐moment basis in diabetics for a period of several days. By comparing the glycemic controls with those obtained in each patient with intensified multiple insulin injection regimes, the superiority of feedback control with the system was clearly demonstrated. These data might indicate the feasibility of long‐term glycemic control in ambulatory diabetic patients with a wearable closed‐loop glycemic control system.

On the Annotation of Web Videos by Efficient Near-Duplicate Search (2010)

With the proliferation of Web 2.0 applications, user-supplied social tags are commonly available in social media as a means to bridge the semantic gap. On the other hand, the explosive expansion of social web makes an overwhelming number of web videos available, among which there exists a large number of near-duplicate videos. In this paper, we investigate techniques which allow effective annotation of web videos from a data-driven perspective. A novel classifier-free video annotation framework is proposed by first retrieving visual duplicates and then suggesting representative tags. The significance of this paper lies in the addressing of two timely issues for annotating query videos. First, we provide a novel solution for fast near-duplicate video retrieval. Second, based on the outcome of near-duplicate search, we explore the potential that the data-driven annotation could be successful when huge volume of tagged web videos is freely accessible online. Experiments on cross sources (annotating Google videos and Yahoo! videos using YouTube videos) and cross time periods (annotating YouTube videos using historical data) show the effectiveness and efficiency of the proposed classifier-free approach for web video tag annotation.
Receptor-Mediated Endocytosis of Alpha2 -Macroglobulin and Transferrin in Rat Caput Epididymal Epithelial Cells In Vitro (1984)

The endocytic activity of epithelial cells from the rat epididymis in vitro has been examined by following the uptake of tracer compounds conjugated to proteins. Transferrin-gold and alpha 2-macroglobulin-gold were taken up initially in coated pits, internalized and sequestered into tubular-vesicular structures, multivesicular bodies and, in the case of alpha 2-macroglobulin, into lysosomes. Uptake could be prevented by an excess of unlabeled protein. Studies using 125I-alpha 2-macroglobulin and 125I-transferrin also showed that the uptake of these proteins was specific and could be displaced with increasing amounts of unlabeled protein. In addition, binding of 125I-transferrin to cells was saturable at 4 degrees C. These studies indicate that transferrin and alpha 2-macroglobulin are taken up by receptor-mediated endocytosis. In contrast, a fluid phase marker, bovine serum albumin-gold (BSA-gold), was initially taken up predominantly in uncoated caveolae rather than coated pits, and could not be displaced with excess BSA. By virtue of their charge, polycationized ferritin and unlabeled colloidal gold were taken up and internalized by adsorptive endocytosis, a pathway which is similar to fluid phase endocytosis. The uptake and internalization of alpha 2-macroglobulin and transferrin differed in a number of respects. Uptake and internalization of alpha 2-macroglobulin but not of transferrin was dependent on extracellular calcium. Only alpha 2-macroglobulin was transferred into lysosomes, whereas transferrin was recycled to the cell surface. Although the proton ionophore, monensin, and the transglutaminase inhibitor, dansylcadaverine, did not stop uptake and internalization of either alpha 2-macroglobulin or transferrin, they did prevent the transfer of alpha 2-macroglobulin to lysosomes.
Selective checkpointing and rollbacks in multi-threaded object-oriented environment (1999)

This paper presents selective checkpointing and rollback schemes for MT-OO (multithreaded, object-oriented) programs. There is a need for checkpointing mechanisms that are more sophisticated than the traditional process-level checkpointing. The program model, theoretical foundations, and an implementation of the selective checkpointing and rollback schemes are described. The usefulness of the schemes is demonstrated by implementing a higher level fault-tolerance scheme of conversations using them. The performance implications are studied on a prototype Internet e-commerce-server. The use of the selective schemes in the prototype server showed an appreciable reduction in the loss of work in the presence of faults. Benefits are more pronounced for a larger level of concurrency in the server. The selective scheme usually outperforms the hypothetical zero-cost global scheme in the presence of faults, vis-a-vis completion times. The experiments also show the vast difference between the sizes of selective checkpoints and global checkpoints. The concurrent sessions scheme (based on the concept of relaxed conversations) required 160 checkpoints in less than an hour. Traditionally, such a scheme would be considered outrageous, but the selective schemes still improve performance in the presence of faults.
Optimization of linear sparse array antennas consisting of electromagnetically coupled apertures (2004)

A design technique for sparse array configurations consisting of dielectric-filled, open-ended waveguide antennas is discussed. The position of the elements in the thinned array are determined by applying a genetic algorithm that searches for configurations with the lowest side-lobe level. By employing as design parameter the relative inter-element spacing, the formulated optimization problem allows for an arbitrary deployment of the elements on the aperture. The design strategy accounts for the mutual coupling between elements, as well. To this end, an efficient technique for estimating the Generalized Scattering Matrix of a-periodic arrays is proposed.

A performance analysis for two TCM code combining diversity receivers (2002)

Trellis coded modulation is widely used for digital transmission over fading channels. Classical diversity techniques are also frequently employed to combat fading. Two different combining strategies are compared. One scheme is based on an interleaved code combining technique. The alternative scheme is based on averaged diversity combining. The well known transfer function bounding technique for trellis codes is used to obtain expressions for the bit error rate performance of the two trellis coded diversity receivers over a slowly fading Rayleigh channel. The analysis of interleaved code combining is a straightforward modification of the analysis for multiple trellis coded modulation. The analysis of averaged diversity combining is accommodated through a more involved, novel modification of the branch labeling of the error state diagram.
Advanced Characterization of HAZ Softening of AHSS for Crash Modeling (2017)

Advanced characterization of the mechanical properties in the softened HAZ is vital for designing welded AHSS components, as it is needed to predict post-weld performance, such as during crash. The weld heat affected zone (HAZ) of advanced high strength steels (AHSS) containing significant volume fractions of martensite exhibit considerable softening because of tempering effects. HAZ softening of two AHSS; Usibor 1500 (press hardening steel) and M1500 with nominal ultimate tensile strength (UTS) of 1500 MPa has been characterized in this study. Samples were subjected to various rapid tempering cycles using the Gleeble to simulate the microstructures found in different locations of the sub-critical HAZ. Mechanical properties of simulated weld areas have been measured with different geometries, representing different levels of stress triaxiality. Furthermore, Digital Image Correlation (DIC), to determine fracture strain of HAZ, measured the fracture strain of a spot weld and base metal for Usibor 1500. Uniaxial tensile and notch sample geometries were used to investigate the influence of different strain path. The results show fracture strain is a weak function of strain path for samples that fail in the HAZ, whereas fracture strain of the base material considerably depends on strain path.
Higher-order QAM data transmission using a high-coherence hybrid Si/III–V semiconductor laser (2020)

We experimentally demonstrate the use of a high-coherence hybrid silicon (Si)/III-V semiconductor laser as the light source for a transmitter generating 20 Gbaud 16- and 64- quadrature amplitude modulated (QAM) data signals over an 80 km single-mode fiber (SMF) link. The hybrid Si/III-V laser has a measured Schawlow-Townes linewidth of ${\sim}{10}\;{\rm kHz}$∼10kHz, which is achieved by storing modal optical energy in low-loss Si, rather than the relatively lossy III-V materials. We measure a received bit error rate (BER) of ${4.1} \times {{10}^{ - 3}}$4.1×10<sup>-3</sup> when transmitting the 64-QAM data over an 80 km SMF using the hybrid Si/III-V laser. Furthermore, we measure a BER of $ {\lt} {1} \times {{10}^{ - 4}}$<1×10<sup>-4</sup> with the Viterbi-Viterbi digital carrier phase recovery method when transmitting the 16-QAM data over an 80 km SMF using the hybrid Si/III-V laser. This performance is achieved at power penalties lower than those obtained with an exemplary distributed feedback laser and slightly higher than those with an exemplary narrow-linewidth external cavity laser.
Application of the Ugi four-component reaction to the synthesis of ditopic bifunctional chelating agents (2009)

The Ugi four-component reaction (Ugi 4CR) was exploited for the first time to obtain in a single synthetic step bifunctional ditopic chelators by using DOTA monoamide (DOTAMA) derivatives as amino and acid components. A number of ditopic systems in which the two DOTAMA units are connected by a central alpha-acylaminoamide group were synthesized by reacting different aldehydes, isocyanides and two DOTAMA chelates containing amino and acid functionalities. Variation of the components allows the insertion of another functional group into the alpha-acylaminoamide skeleton for further conjugation to biomolecules. The optimal reaction conditions were found by using methanol as solvent and ultrasound irradiation at a power of 60 W (20 kHz) for 3 h. The Gd(III) complexes of the dimeric ligands L1 and L2 (bearing a cyclohexyl ring and an octadecyl chain on the central alpha-acylaminoamide moiety, respectively) were fully characterized in aqueous media by relaxometric techniques with varying temperature and magnetic field strength. The relaxivity of Gd(2)L1 and Gd(2)L2 (in the aggregated form), at 20 MHz and 310 K, are 5.6 and 20.0 mM(-1) s(-1), respectively. The enhanced value found for Gd(2)L2 indicates that this lipophilic complex forms micelles at concentrations <0.1 mM. Finally, the binding of Gd(2)L2 to human serum albumin (HSA) was investigated by proton relaxometry, and the affinity constant of the complex and the relaxivity of the macromolecular adduct (r(1p)(b) = 38.1 mM(-1) s(-1); 20 MHz and 310 K) derived.
Semiconductor-Metal Eutectic Composites For High-Power Switching (1988)

A novel electronic material, a Si-TaSi<sub>2</sub> semiconductor-metal eutectic composite, offers promise in high-power switching applications. In this paper, the basic electronic properties of the material are briefly described. It is shown that the in situ Schottky junctions inherent to the material can be used to fabricate transistors. The advantages of these devices are their volumetric current transport and their unusual resistance to avalanche breakdown.
A Novel Stall Warning Indicator: Part I — Applications and Limitations (2019)

Abstract The present work is the first of two papers investigating the operation principle of stall warning quantities. It discusses the use and implementation of novel stall warning techniques based on experimental tests. Each of the addressed techniques is based upon integral statistical analysis of time-resolved wall pressures in close proximity to the leading edge of a compressor rotor. The experiments were conducted on a low speed axial compressor test rig at the Chair of Aeroengines at the Technische Universität Berlin. The compressor suffers from a specific type of pre-stall instability. The signature within the frequency spectrum of this semi-stable operating point is in itself unique and was observed by many within the scientific community on numerous occasions and various axial compressor types, both low and high speed. Strong evidence has been elaborated which indicate that each of those so called stall warning indicator’s functionality is based upon the existence of this prestall phenomena. The first of two indicators is time-dependent as it evaluates the as-is state against surrounding operating points during transient manoeuvres. Furthermore, the impact of varying geometrical boundary conditions, which are known to regularly arise in flight operations, were taken into account. The functionality of the indicator is assured if the instrumentation is adjusted accordingly. The second indicator is mainly a location-dependent quantity as it evaluates the pressure signature along the axial direction within the rotor passage at various aerodynamic loadings. The latter also gave rise to some fundamental and preliminary understanding of the physics behind so called prestall disturbances.

Abstract 19085: Outcomes After Cardiopulmonary resuscitation With Chest Compressions Only versus Conventional CPR: A Meta-Analysis of 84,888 Patients (2013)

Objectives: Optimal method of by-stander cardiopulmonary resuscitation (CPR) is still controversial. Studies comparing “chest compressions only CPR” with “conventional CPR” have yielded mixed results. We intended to compare the effectiveness of the above two strategies on survival after cardiac arrest out of hospital by performing a meta-analysis of all available clinical studies till date. Methods: We searched Medline and Embase for randomized control trials (RCT) and prospective observational studies comparing “chest compressions only CPR” with “conventional CPR”. Only studies presenting survival outcomes were included. Random effects model with inverse variance weighting was used to calculate pooled risk ratio (RR). Subgroup analyses were also performed as deemed necessary. Results: We identified 15 studies (12 observational and 3 RCTs) including 84,888 patients, of whom 39,572 received chest compressions only and 45,316 received conventional CPR. There was no significant difference in the survival with either technique (RR: 1.08; 0.93 - 1.26, p = 0.33). Exclusion of one study which reported only neurologically favorable survival did not alter the composite analysis. There was a significant heterogeneity among the studies (I2 = 85%, p&lt;0.001). Begg’s and Egger’s regression test did not reveal any publication bias. Sub-group analyses of observational studies (RR: 0.97; 0.85-1.12, p=0.71) and RCTs (RR: 1.6; 0.88 - 3.1, p =0.12) did not demonstrate any difference in the survival outcome between the two techniques. Conclusion: By-stander “chest compressions-only CPR” is associated with similar survival rate when compared to “conventional CPR”.

Oriented CoSAPO‐5 Membranes by Microwave‐Enhanced Growth on TiO2‐Coated Porous Alumina (2012)

Microwaving plates: A facile method was developed for the fabrication of preferentially c-oriented cobalt-substituted silicoaluminophosphate-5 (CoSAPO-5) membranes on porous alumina supports. In situ microwave growth using a slip-coated TiO2 layer on the support surface resulted in an oriented CoSAPO-5 crystal layer, which was evolved into a defect-free membrane by improving crystalline intergrowth through secondary hydrothermal microwave growth.

The past, present, and future of head-mounted display designs (2005)

Head-mounted displays present a relatively mature option for augmenting the visual field of a potentially mobile user. Ideally, one would wish for such capability to exist without the need to wear any view-aided device. However, unless a display system could be created in space, anywhere and anytime, a simple solution is to wear the display. We review in this paper the fundamentals of head-mounted displays including image sources and HMD optical designs. We further point out promising research directions that will play a key role towards the seamless integration between the virtually superimposed computer graphics objects and the tangible world around us.

Removal of urea by electro-oxidation in a miniature dialysis device: a study in awake goats (2018)

The key to success in developing a wearable dialysis device is a technique to safely and efficiently regenerate and reuse a small volume of dialysate in a closed-loop system. In a hemodialysis model in goats, we explored whether urea removal by electro-oxidation (EO) could be effectively and safely applied in vivo. A miniature dialysis device was built, containing 1 or 2 "EO units," each with 10 graphite electrodes, with a cumulative electrode surface of 585 cm<sup>2</sup> per unit. The units also contained poly(styrene-divinylbenzene) sulfonate beads, FeOOH beads, and activated carbon for respective potassium, phosphate, and chlorine removal. Urea, potassium, and phosphate were infused to create "uremic" conditions. Urea removal was dependent on total electrode surface area [removal of 8 mmol/h (SD 1) and 16 mmol/h (SD 2) and clearance of 12 ml/min (SD 1) and 20 ml/min (SD 3) with 1 and 2 EO units, respectively] and plasma urea concentration but not on flow rate. Extrapolating urea removal with 2 EO units to 24 h would suffice to remove daily urea production, but for intermittent dialysis, additional units would be required. EO had practically no effects on potassium and phosphate removal or electrolyte balance. However, slight ammonium releasewas observed, and some chlorine release at higher dialysate flow rates. Minor effects on acid-base balance were observed, possibly partly due to infusion of chloride. Mild hemolysis occurred, which seemed related to urea infusion. In conclusion, clinically relevant urea removal was achieved in vivo by electro-oxidation. Efficacy and safety testing in a large-animal model with uremia is now indicated.
Modificación reológica de residuos de PET. Pultrusión termoplástica como tecnología de reciclado (2021)

Packaging sector generates 40% of the plastics consumption in Europe. Among Among the most consumed plastics Polyethylene terephthalate (PET) is still the material that undoubtedly continues to grow in the packaging sector. Because of that, there is a concern related to the recycling process, which today is only around 56%. This makes that at present, there are tons of thermoplastic material accumulated in landfills that could be a potential source of raw material (especially colored PET and multilayer). On the other hand, like PET waste (RPET), there are environmental problems associated with the disposal of composite materials in landfills, especially thermoset matrix composites.
In this sense, due to the impossibility of recycling and reusing thermosetting composites, thermosets have composites are beginning to be replaced by thermoplastics. However, the main problem in the use of thermoplastic matrices in composite materials lies in the total impregnation of the reinforcement of the fiber due to the high viscosities of these materials. With the purpose of solving this limitation, and joining these needs, this work has been focused on obtaining new materials by modifying the less recyclable fractions of RPET. In this sense this material has been modified rheologically by reactive extrusion to replace thermosetting materials in the manufacture of composites, especially in thermoplastic pultrusion. From the first materials developed it has been possible to manufacture profiles from matrix 100% recycled material with adequate impregnation. The results of this study transform a waste into a product with high added value, reducing the carbon footprint and the costs of the process.
