Serial Breast Magnetic Resonance Imaging to Enhance Safety following Autologous Fat Injection after Breast Cancer? (2010)

Sir: We read with great interest the recent clinical report by Dr. Serra-Renom and colleagues regarding fat grafting in postmastectomy patients with expanders and prosthesis following radiotherapy.1 We would like to congratulate the authors on their impressive clinical results. However, we would like to highlight potential safety issues. The authors combined serial fat grafting in the irradiated breast skin and the muscle with subsequent expander and later prosthesis for secondary breast reconstruction. Follow-up was 12 months. Clinically, no complications were reported. Given the introduction of the BREAST-Q, one might consider using this valuable tool in this patient cohort.2 Recently, the BREAST-Q has been applied to compare patient satisfaction and health-related quality of life following breast reconstruction with either saline or silicone gel implants.3 The authors achieved impressive clinical results, with high patient satisfaction. However, autologous fat injection into the breast is not necessarily a simple and straightforward procedure, which might be delineated by this report. Recently, the Journal has presented a case series of 12 patients suffering complications following autologous fat transplantation in Japan.4 Four of 12 patients had abnormalities on breast cancer screening. The authors concluded that patients should be thoroughly informed about a potential risk of calcification and should be followed over a long term with imaging analysis. Magnetic resonance imaging is one valid option in this regard.5 Notably, volumetry of the autologous fat tissue transferred is achievable using magnetic resonance imaging–based algorithms.6 Thus, unless prospective higher level evidence-based recommendations are applicable, one might consider serial magnetic resonance imaging following fat injection in the breast for volumetry to assess efficacy and longevity of the autologous fat transplantation and to improve and enhance patient safety in terms of potential adverse effects. However, the costs of such serial magnetic resonance imaging have to be taken into account in this regard. Karsten Knobloch, M.D., Ph.D. Christian Herold, M.D. Hans-Oliver Rennekampff, M.D. Peter M.

New Solutions Based On Wireless Networks For Dynamic Traffic Lights Management: A Comparison Between IEEE 802.15.4 And Bluetooth (2015)

Abstract The Wireless Sensor Networks are widely used to detect and exchange information and in recent years they have been increasingly involved in Intelligent Transportation System applications, especially in dynamic management of signalized intersections. In fact, the real-time knowledge of information concerning traffic light junctions represents a valid solution to congestion problems. In this paper, a wireless network architecture, based on IEEE 802.15.4 or Bluetooth, in order to monitor vehicular traffic flows near to traffic lights, is introduced. Moreover, an innovative algorithm is proposed in order to determine dynamically green times and phase sequence of traffic lights, based on measured values of traffic flows. Several simulations compare IEEE 802.15.4 and Bluetooth protocols in order to identify the more suitable communication protocol for ITS applications. Furthermore, in order to confirm the validity of the proposed algorithm for the dynamic management of traffic lights, some case studies have been considered and several simulations have been performed.
Supported titanium‐magnesium catalysts for ethylene polymerization: A comparative study of catalysts containing isolated and clustered titanium ions in different oxidation states (2009)

Abstract Supported titanium–magnesium catalysts (TMC) comprising isolated and clustered titanium ions in different oxidation states, which are obtained using titanium compounds of different composition (TiCl 4 , TiCl 3 • n DBE (DBE – dibutyl ether), [η 6 –BenzeneTiAl 2 Cl 8 ]), were synthesized and tested in ethylene polymerization. The state of titanium ions was studied by the ESR method both for the procatalysts and after their interaction with triisobutilaluminum. For identification of ESR‐silent Ti 3+ ions and Ti 2+ ions, special procedures of additional catalyst treatment with pyridine, water, and chloropentafluorobenzene were used to obtain Ti 3+ ions that are observable in ESR spectra. In distinction to numerous earlier works performed with the TiCl 4 /MgCl 2 catalyst comprising after the interaction with AlR 3 the Ti 3+ surface compounds both as isolated ions and clusters (ESR‐silent), this work considers the [η 6 –BenzeneTiAl 2 Cl 8 ]/MgCl 2 catalyst (TMC‐3) comprising mainly the isolated Ti 2+ ions and a new catalyst TMC‐4 obtained by treating the TMC‐3 with chloropentafluorobenzene. This catalyst comprises only the isolated Ti 3+ ions both before and after the interaction with triisobutylaluminum. It was shown that in spite of sharp distinctions between the catalysts under consideration concerning titanium oxidation state and the ratio of isolated Ti 3+ ions to clustered ones, all these catalysts produce polyethylenes with similar molecular weights and molecular‐weight distributions. © 2009 Wiley Periodicals, Inc.

Optimal powertrain design and control of a 2-IWD electric race car (2017)

In this work, the optimal powertrain design and control problem of a 2-independent-wheel-driving (2-IWD) electric race car aiming at minimizing the lap time on a given track is formulated and solved with a developed optimal control software GDYNOPT, which is based on the direct transcription method and nonlinear programming (NLP). There are three innovative features of this work with respect to the state of the art literature. The first original contribution is that both the static design parameters of the powertrain and time variant control parameters are selected as the parameters to be optimized in the formulated problem. The second one is that a nonlinear load transfer model considering the aerodynamics is derived and taken into account in the formulated problem. The last one is that the dependence of the mass of the powertrain on the design parameters is considered and described with the derived mass model of the motors and gearboxes. The formulated optimal design and control problem with a 7 degrees of freedom (7-DOF) vehicle model considering the nonlinear load transfer moving in a curvilinear coordinated system is solved. The obtained results of the optimal design and control are presented in the last section of this paper.

Learning interpretable models of phenotypes from whole genome sequences with the Set Covering Machine (2014)

The increased affordability of whole genome sequencing has motivated its use for phenotypic studies. We address the problem of learning interpretable models for discrete phenotypes from whole genomes. We propose a general approach that relies on the Set Covering Machine and a k-mer representation of the genomes. We show results for the problem of predicting the resistance of Pseudomonas Aeruginosa, an important human pathogen, against 4 antibiotics. Our results demonstrate that extremely sparse models which are biologically relevant can be learnt using this approach.
Root growth inhibition by low temperature explains differences in sugar accumulation between spring and winter wheat (2001)

Exposure to low temperatures is associated with an increased concentration of carbohydrate (mainly sugar) in tissues of cool temperate species. Within a species, carbohydrate concentration is usually much higher in winter cultivars than in spring ones, frequently correlates well with winter survival, and is also related to the expression of several genes. It has been proposed that either a smaller reduction in carbon assimilation, or greater growth inhibition by cold in winter cultivars, might explain this differential increase in carbohydrate concentration. However, little experimental support for these hypotheses is available. In this work, carbon assimilation and growth, as related to the cold-induced increase in carbohydrate concentration, are analysed in contrasting wheat ( Triticum aestivum L.) genotypes. No significant differences in the degree of cold-induced reduction of carbon assimilation between cultivar types were found. Also, shoot growth was similarly inhibited by cold in both winter and spring cultivars. However, root growth rates were lower in cold-treated winter cultivars than in spring ones, which led to much larger root systems in the latter. A simple method for quantitatively estimating the contribution of cold-induced changes in carbon fixation and growth to changes in carbohydrate concentration was developed. This analytical framework suggests that the degree of root growth inhibition by cold was the main factor in determining differences in carbohydrate content between cultivars.
An improved bang-bang phase detector for clock and data recovery applications (2002)

A low power fully integrated PLL-based 5 Gb/s NRZ clock and data recovery circuit was successfully implemented in a 0.18 /spl mu/m CMOS process. A novel bang-bang phase detector, used in the implementation, resulted in improved jitter performance compared to conventional bang-bang detectors. Differential topologies were used for the charge-pump and VCO circuits to reduce the design sensitivity to power supply noise. The maximum measured clock jitter from a 2/sup 23/-1 pseudorandom bit stream (PRBS) input data was less than 4.8 ps rms. The total power dissipation was less than 80 mW from a 1.8 V supply.

Investigations of the Regeneration Step of a Thermochemical Cycle Using Mixed Iron Oxides Coated on SiSiC Substrates (2011)

A two-step thermochemical cycle for hydrogen production using mixed iron oxides coated on silicon carbide substrates has been investigated. The water-splitting step proceeds at temperatures between 800 and 1000 °C while for the regeneration step temperatures around 1200 °C are needed. A deactivation of the material resulting in a decrease of the hydrogen production within the first couple of cycles was observed in preceding tests. For detailed investigations of the system composed of the redox-material and the substrate small scale samples were tested in a laboratory test-rig. For identification of material changes the samples were investigated via XRD and SEM-EDS analysis. The analysis revealed the reasons for the deactivation of the redox-material. Through parametric studies the influence of the regeneration parameters, namely regeneration temperature and time on the hydrogen production was analysed. A model for the regeneration step was developed describing the performance of the regeneration step as a function of temperature and time and additionally as a function of total regeneration time, i.e. the cumulated time the sample has been regenerated.
Vaccination Accelerates Liver-Intrinsic Expression of Megakaryocyte-Related Genes in Response to Blood-Stage Malaria (2022)

Erythropoiesis and megakaryo-/thrombopoiesis occur in the bone marrow proceeding from common, even bipotent, progenitor cells. Recently, we have shown that protective vaccination accelerates extramedullary hepatic erythroblastosis in response to blood-stage malaria of <i>Plasmodium chabaudi.</i> Here, we investigated whether protective vaccination also accelerates extramedullary hepatic megakaryo-/thrombopoiesis. Female Balb/c mice were twice vaccinated with a non-infectious vaccine before infecting with 10<sup>6</sup>&nbsp;<i>P. chabaudi</i>-parasitized erythrocytes. Using gene expression microarrays and quantitative real-time PCR, transcripts of genes known to be expressed in the bone marrow by cells of the megakaryo-/thrombocytic lineage were compared in livers of vaccination-protected and unprotected mice on days 0, 1, 4, 8, and 11 <i>p.i.</i> Livers of vaccination-protected mice responded with expression of megakaryo-/thrombocytic genes faster to <i>P. chabaudi</i> than those of unvaccinated mice, evidenced at early patency on day 4 <i>p.i.</i>, when livers exhibited significantly higher levels of malaria-induced transcripts of the genes <i>Selp</i> and <i>Pdgfb</i> (<i>p</i>-values < 0.0001), <i>Gp5</i> (<i>p</i>-value < 0.001), and <i>Fli1</i>, <i>Runx1</i>, <i>Myb</i>, <i>Mpl</i>, <i>Gp1ba</i>, <i>Gp1bb</i>, <i>Gp6</i>, <i>Gp9</i>, <i>Pf4</i>, and <i>Clec1b</i> (<i>p</i>-values < 0.01). Together with additionally analyzed genes known to be related to megakaryopoiesis, our data suggest that protective vaccination accelerates liver-intrinsic megakaryo-/thrombopoiesis in response to blood-stage malaria that presumably contributes to vaccination-induced survival of otherwise lethal blood-stage malaria.
Corneal stromal abscessation in two horses treated with intracorneal and subconjunctival injection of 1% voriconazole solution (2012)

This procedure may be an effective technique to treat refractory or relapsing DSA in horses. Intracorneal and subconjunctival voriconazole administration results in a visual and cosmetically acceptable globe. In equine DSA cases, the advantages of this technique compared with other medical and surgical approaches to this disease include shortened anesthesia times, minimal resultant scarring and shorter healing times, and lower cost of therapy.
Developmental Course of Nighttime Sleep-Wake Patterns in Full-Term and Premature Infants During the First Year of Life. I. (1985)

Two groups of infants (40 normal full-term, 24 prematurely born infants) were matched on conceptional age and were studied at seven ages during the first year of life. All-night time-lapse video somnography was obtained n the home at 2, 4, 8, 20, 24, 36, and 52 weeks of age. The developmental course of sleep-wake state proportions, sleep onset indices, and special variables assessing temporal organization are compared. Age-appropriate developmental norms for sleep-wake state assessment during the first year of life are presented, using video somnography. In general, sleep-wake state ontogenesis is comparable in the two groups. The premature group is more variable from one age to the next, even though both groups demonstrate significant individual stability of some sleep-wake variables over the first year of life.
Variable density multilayer insulation for cryogenic storage (2000)

Two analytical models for a foam/Variable Density Multi-Layer Insulation (VD-MLI) system performance are discussed. Both models are one-dimensional and contain three heat transfer mechanisms, namely conduction through the spacer material, radiation between the shields, and conduction through the gas. One model is based on the methodology developed by McIntosh while the other model is based on the Lockheed semi-empirical approach. All models input variables are based on the Multi-purpose Hydrogen Test Bed (MHTB) geometry and available values for material properties and empirical solid conduction coefficient. Heat flux predictions are in good agreement with the MHTB data, The heat flux predictions are presented for the foam/MLI combinations with 30, 45, 60, and 75 MLI layers
A vehicle model for micro-traffic simulation in dynamic urban scenarios (2011)

In order to improve energy efficiency of transport systems, eco-driving strategies are studied world-widely. However, most literatures on eco-driving based on traditional traffic flow models, are greatly simplified, and can not evaluate the effects on detailed driving behaviors. By referring to robot motion planning approaches, in this research a microscopic vehicle model is developed and it can represent different driving behaviors, such as aggressive or conservative driving; a collision detection algorithm is proposed that takes O(1) time to check for a trajectory's collision, enabling realtime planning; and a traffic simulation system is developed by incorporating traffic rules, so that the driving behaviors such as observing or not observing traffic rules can also be represented. Experiments are conducted on the simulation platform, and the performance of different driving behaviors on travel time, mileage, comfort and eco is studied.
Expression Profiling of Murine Double-Negative Regulatory T Cells Suggest Mechanisms for Prolonged Cardiac Allograft Survival (2005)

Recent studies have demonstrated that both mouse and human alpha beta TCR(+)CD3(+)NK1.1(-)CD4(-)CD8- double-negative regulatory T (DN Treg) cells can suppress Ag-specific immune responses mediated by CD8+ and CD4+ T cells. To identify molecules involved in DN Treg cell function, we generated a panel of murine DN Treg clones, which specifically kill activated syngeneic CD8+ T cells. Through serial cultivation of DN Treg clones, mutant clones arose that lost regulatory capacity in vitro and in vivo. Although all allogeneic cardiac grafts in animals preinfused with tolerant CD4/CD8 negative 12 DN Treg clones survived over 100 days, allograft survival is unchanged following infusion of mutant clones (19.5 +/- 11.1 days) compared with untreated controls (22.8 +/- 10.5 days; p < 0.001). Global gene expression differences between functional DN Treg cells and nonfunctional mutants were compared. We found 1099 differentially expressed genes (q < 0.025%), suggesting increased cell proliferation and survival, immune regulation, and chemotaxis, together with decreased expression of genes for Ag presentation, apoptosis, and protein phosphatases involved in signal transduction. Expression of 33 overexpressed and 24 underexpressed genes were confirmed using quantitative real-time PCR. Protein expression of several genes, including Fc epsilon RI gamma subunit and CXCR5, which are >50-fold higher, was also confirmed using FACS. These findings shed light on the mechanisms by which DN Treg cells down-regulate immune responses and prolong cardiac allograft survival.

Structured superposition for backhaul constrained cellular uplink (2009)

In this paper, we demonstrate the advantage of the inherent algebraic structure of lattice codes, for the uplink channel of a cellular deployment. The out-of-cell interference is assumed to be symmetric, as in Wyner's model. We employ a new relaying technique, compute-and-forward, which allows cell-sites to decode equations of the transmitted bits by exploiting the channel interference. However, the standard compute-and-forward technique is penalized whenever the channel coefficients are non-integer. We develop a superposition strategy to mitigate this penalty. By using part of the power towards a private message, we can effectively modify the channel seen by compute-and-forward. We demonstrate that, in certain regimes, this mixed strategy significantly outperforms decode-and-forward, compress-and-forward, and ordinary compute-and-forward.
