Electronic and Thermal Transport Properties of Complex Structured Cu‐Bi‐Se Thermoelectric Compound with Low Lattice Thermal Conductivity (2013)

Monoclinic Cu x+y Bi 5−y Se 8 structure has multiple disorders, such as randomly distributed substitutional and interstitial disorders by Cu as well as asymmetrical disorders by Se. Herein, we report the correlation of electronic and thermal properties with the structural complexities of Cu x+y Bi 5−y Se 8 . It is found that the interstitial Cu site plays an important role not only to increase the electrical conductivity due to the generation of electron carriers but also to reduce the thermal conductivity mainly due to the phonon scattering by mass fluctuation. With impurity doping at the interstitial Cu site, an extremely low lattice thermal conductivity of 0.32 W·m −1 ·K −1 was achieved at 560 K. These synergetic effects result in the enhanced dimensionless figure of merit ( ZT ).
Solving systems of linear equations on a quantum computer (2013)

Systems of linear equations are used to model a wide array of problems in all fields of science and engineering. Recently, it has been shown that quantum computers could solve linear systems exponentially faster than classical computers, making for one of the most promising applications of quantum computation. Here, we demonstrate this quantum algorithm by implementing various instances on a photonic quantum computing architecture. Our implementation involves the application of two consecutive entangling gates on the same pair of polarisation-encoded qubits. We realize two separate controlled-NOT gates where the successful operation of the first gate is heralded by a measurement of two ancillary photons. Our work thus demonstrates the implementation of a quantum algorithm with high practical significance as well as an important technological advance which brings us closer to a comprehensive control of photonic quantum information.
Rapid Exclusion of COVID Infection With the Artificial Intelligence Electrocardiogram (2021)

Infection with SARS-CoV-2 results in electrocardiographic changes that permit the artificial intelligence-enhanced ECG to be used as a rapid screening test with a high negative predictive value (99.2%). This may permit the development of electrocardiography-based tools to rapidly screen individuals for pandemic control.
Hip Replacement Simulator for Predicting Dislocation Risk (2016)

This paper reports development of a novel haptic 3D computer-based hip replacement simulator. A haptic device provides a kinesthetic interface in a virtual environment to conduct hip surgery. Predictive software enables modelling the risk of hip dislocation which was missing from previous simulators. The developed neural network autonomously matches compatible implant components from a library of industry standard part codes and sizes. The parameter driven simulator enables patient-specific modeling of femur and acetabulum. Combining haptic feedback with 3D graphics, the simulator enables training and assessment of orthopedic surgeons. The simulator includes haptic feedback for the orthopedic tools including reamer, saws, hip stems, acetabular cup implants. The hip replacement simulator allows surgeons to practice placing the stem and cup, providing a haptic sense of touch to replicate the in-vivo procedure. The novel capability to assess risk of dislocation could reduce post-operative dislocation. Enhancing the skill and accuracy of trainee hip surgeons can reduce the number of revision surgeries required, extend the life of artificial hip implants and improve patient safety, reducing costs for the health service.
Using a Situational Awareness Display to Improve Rider Trust and Comfort with an AV Taxi (2019)

There is evidence that a significant portion of the population does not trust automated vehicles (AV). Research on trust in automation suggests that providing insight into how automation functions via a situational awareness (SA) display improves trust. However, it is unclear how much information is needed to build trust. A study was conducted to evaluate what amount of information improves passenger trust with an AV. After a ride in a simulated AV with one of four SA displays with varying amounts of information or no SA display, participants completed questions about trust and comfort. In addition, participants completed a card sorting task to determine what content they desired to see on the SA display. Our conclusions suggests that an SA display engenders trust and comfort. However, such a display should present a low amount of information. A possible explanation is that high information density displays might be more difficult for participants to interpret.

Molecular Cloning of a $\beta$-D-Galactosidase Gene from Lactococcus lactis subsp. lactis 7962 (1996)

The -galactosidase gene from Lactococcus lactis subsp. lactis ATCC 7962 was cloned and its enzymatic properties were characterized, with a view to assessing its potential use as a selection marker in the food-grade cloning vector. Chromosomal DNA from L. lactis subsp. lactis 7962 was cleaved with PstI and ligated into pBR322 for transformation into Escherichia coli TGl. Transformants showing -galactosidase activity possessed the pBR322 plasmid containing a 10 kilobase (kb) PstI fragment and this plasmid was named pCKL11. The cloned -galactosidase gene came from the chromosomal DNA of L. lactis subsp. lactis 7962 was confirmed by Southern hybridization. A restriction map of pCKL11 was constructed from the cleavage of both pCKL11 and the purified 10kb insert fraqment. The. optimum pH of the -galactosidase determined with the E. coli harboring the pCKL11 was 7.0. The optimum temperature was , while the pI of the enzyme was 7.4. These values were the same as those of the enzyme from the parent strain.
Targeting Cardiac Mast Cells: Pharmacological Modulation of the Local Renin-Angiotensin System (2011)

Enhanced production of angiotensin II and excessive release of norepinephrine in the ischemic heart are major causes of arrhythmias and sudden cardiac death. Mast cell-dependent mechanisms are pivotal in the local formation of angiotensin II and modulation of norepinephrine release in cardiac pathophysiology. Cardiac mast cells increase in number in myocardial ischemia and are located in close proximity to sympathetic neurons expressing angiotensin AT1- and histamine H3-receptors. Once activated, cardiac mast cells release a host of potent pro-inflammatory and pro-fibrotic cytokines, chemokines, preformed mediators (e.g., histamine) and proteases (e.g., renin). In myocardial ischemia, angiotensin II (formed locally from mast cell-derived renin) and histamine (also released from local mast cells) respectively activate AT1- and H3-receptors on sympathetic nerve endings. Stimulation of angiotensin AT1-receptors is arrhythmogenic whereas H3-receptor activation is cardioprotective. It is likely that in ischemia/reperfusion the balance may be tipped toward the deleterious effects of mast cell renin, as demonstrated in mast cell-deficient mice, lacking mast cell renin and histamine in the heart. In these mice, no ventricular fibrillation occurs at reperfusion following ischemia, as opposed to wild-type hearts which all fibrillate. Preventing mast cell degranulation in the heart and inhibiting the activation of a local renin-angiotensin system, hence abolishing its detrimental effects on cardiac rhythmicity, appears to be more significant than the loss of histamine-induced cardioprotection. This suggests that therapeutic targets in the treatment of myocardial ischemia, and potentially congestive heart failure and hypertension, should include prevention of mast cell degranulation, mast cell renin inhibition, local ACE inhibition, ANG II antagonism and H3-receptor activation.
RF Amplitude Control in an All-Digital PLL based Transmitter (2005)

Abstract — A fully-digital frequency synthesizer for RF wireless applications has recently been proposed. At its foundation lies a digitally-controlled oscillator that deliberately avoids any ana-log tuning controls. The conventional phase/frequency detector, charge pump and RC loop filter are replaced by a time-to-digital converter and a simple digital loop filter. When implemented in a digital deep-submicron CMOS process, the proposed architecture is more advantageous over conventional charge-pump-based PLL’s since it exploits signal processing capabilities of digital circuits and avoids relying on the fine voltage resolution of analog circuits. In this paper, we present new techniques for achieving amplitude control of the RF output. This approach has been incorporated in a Bluetooth radio realized in 130-nm CMOS. I.
Microreflectivity characterization of the two-dimensional refractive index distribution of electron-beam-written optical waveguides in germanium-doped flame-hydrolysis silica (2004)

In this letter, we report on the detailed refractive index distribution of optical waveguides induced by electron-beam irradiation of Ge-doped flame hydrolysis silica and its variation with dose. The characterization was performed using microreflectivity measurements.
Packaging effects on the figure of merit of a CMOS cascode low-noise amplifier: Flip-chip versus wire-bond (2009)

A comprehensive study is presented to compare the effects between flip-chip and wire-bond packages on a front-end cascode low-noise amplifier (LNA) in a 2.4 GHz CMOS wireless local area network (WLAN) receiver. To construct the package electrical models, specific modeling dies are designed to help extract the equivalent-circuit elements from measured S-parameters for chip-package interconnects. Furthermore, the ground-proximity effect on on-chip spiral inductors in a flip-chip package is presented for the first time in this modeling study. For practical applications, the established package models are used in a chip-package co-simulation to predict the degradation of figure of merit for the cascode LNA under packaged condition.
Evaluation of [131l]iodoerythronitroimidazole as a predictor for the radiosensitizing effect (1996)

The aim of this study was to evaluate whether radiolabeled iodoerythronitroimidazole (IETNIM) could predict the radiosensitization effect on tumors. Tumor-bearing mice were irradiated at a dose of 25, 31 and 37 Gy after the injection of IETNIM. They were also exposed to 37 Gy radiation at 35, 70, 140 and 240 min after the i.p. injection of IETNIM. After the irradiation, tumor growth assays were conducted and the effect of IETNIM as a radiosensitizer was estimated as enhancement factor (EF). Tumor uptake was measured at 35, 70, 140 and 240 min after i.p. injection of [131I]IETNIM, which were the same intervals used in the radiosensitization study. EF of IETNIM in mice treated with 25, 30 and 37 Gy irradiation was 0.72, 0.98 and 1.28, respectively. EF of IETNIM in mice irradiated at 35, 70, 140 and 240 min after the injection was 1.50, 1.69, 1.46 and 1.08, which corresponded to the tumor uptake and blood clearance of [131I]IETNIM. [131I]IETNIM may be a suitable radiopharmaceutical to predict the radiosensitization effect of misonidazole analogs on tumors.
Paramagnetic Defect Generation and Microstructure Change in Porous Low-k SiOCH Films with Vacuum Baking (2010)

We studied in detail the paramagnetic defect generated in the porous low- SiOCH films, which is called the center with the oxygen–carbon mixed back bonds. We baked the SiOCH films in vacuum from 600 to , which could correspond to temperature elevation at a local area in cases of UV or electron-beam curing and Joule heating in circuits. The amount of the center increased abruptly around by electron spin resonance spectroscopy, at which we observed 30% volume shrinkage by ellipsometry and network change from a cage link to a ring link by Fourier transform IR spectroscopy. These phenomena might be due to the crush of microholes wrapping end groups. Therefore, we consider that the generation of the center suggests the quality change of the porous low- SiOCH films for the ultralarge-scale integration reliability.
Static Negative Resistance in Highly Doped Gunn Diodes and Application to Switching and Amplification (1973)

Stationary distributions of the field and the electron density of the trapped domain in highly doped Gunn devices are calculated by a computer simulation and a simple numerical analysis. From these results, characteristics of the bistable switching due to the static negative resistance are clarified against the donor density of the active region. The results of the computer simulation also demonstrates possibilities of the wide band reflection amplification with the frequencies independent of the transit time in the overcritically doped Gunn diodes.
Experimental validation of a new bianisotropic parameter retrieval technique using plasmonic metasurfaces made of V-shape antennas (2013)

We report on a numerical study of a new bianisotropic parameter retrieval technique for both regular and complementary V-shape antenna metasurfaces. Each antenna element with a discrete phase shift is modeled by a homogenous bianisotropic film to represent the optical response. For the complementary design, the retrieval implies a complementary behavior of effective material properties and predicts the analogous functionalities. Further, FDFD solver is developed to integrate the bianisotropic descriptions of each antenna and describes a fully functional metasurface. The computational burden is significantly reduced, because effective material properties replace the detailed meshing of the antennas. Experimentally, large dimension arrays of nano‐voids are fabricated using electron beam lithography. It is demonstrated that cross-polarized light is diffracted towards the same direction. Furthermore, the complementary design greatly increases the extinction ratio of functional fields to background fields.
Dominant Processing Factors in Two-Step Fabrication of Pure Sulfide CIGS Absorbers (2021)

Pure sulfide CIGS solar cells are interesting candidates for standalone solar cells or top cells in a tandem configuration. To understand the limits and improve the power conversion efficiency of these devices, a comprehensive approach aimed at composition, interface, and process engineering should be employed. Here, the latter was explored. Using a two-step fabrication technique and one-variable-at-a-time methodology, we found the four processing factors affecting the absorber the most. While two were already backed by the previous literature, we found new and statistical evidence for two other important factors as well. The impact of alkali barrier diffusion was also established with statistical significance and under various processing conditions. Furthermore, the absorber roughness for samples without a barrier indicated a significant negative linear correlation with the devices’ efficiency. This contribution could aid engineers in more efficient process designs.

Prenatal administration of Lactobacillus rhamnosus has no effect on the diversity of the early infant gut microbiota (2011)

We have recently shown that maternal administration of Lactobacillus rhamnosus GG (LGG) during late pregnancy can have beneficial effects on the early development of infant gut microbiota, promoting a bifidobacteria profile similar to that of a healthy breastfed infant. It is uncertain, however, whether such probiotic supplementation could influence the diversity of infant gut microbiota. We investigated the effect of pre-natal LGG on gut microbial diversity in the early post-natal period. Day-7 faecal samples were collected from 98 infants at high risk of allergic disease, whose mothers participated in a pre-natal probiotic eczema prevention study. Faecal microbial diversity was assessed by terminal restriction fragment length polymorphism using restriction enzymes Sau96I and AluI. A greater number of peaks represent greater diversity of bacterial communities. Administration of LGG to mothers during late pregnancy had no effects on the mean number of peaks in faecal samples from 1-wk-old infants as compared to placebo (AluI 14.4 vs. 15.5, p = 0.17, 95% CI -0.4, 2.5; Sau96I 17.3 vs. 15.8, p = 0.15, 95% CI -3.5, 0.5). Prenatal LGG failed to modulate diversity of early infant gut microbiota despite promoting a beneficial bifidobacteria profile.
A traveltime-based offset-to-angle transform for borehole seismic survey data in anisotropic media (2018)

Borehole seismic reflection amplitude data have the potential to help characterize subsurface formations. Placing receivers closer to the target enables seismic data collected in such surveys to be of a higher signal-to-noise ratio (S/N) and less distorted by wave propagation effects. Practical application of amplitude analysis for such purpose, however, requires accounting for anisotropy while generating angle gathers. Additionally, geometrical spreading needs to be accurately corrected for without compromising efficiency. This work describes an algorithm developed for such purposes, computing spreading corrections and angles in anisotropic media using traveltime tables calculated with heterogeneous velocity models. The method was applied to synthetic data to demonstrate its effectiveness. Angle gathers generated using the algorithm can help characterize reservoirs with less uncertainty.

Basal and Stimulated Calcitonin and Procalcitonin by Various Assays in Patients with and without Medullary Thyroid Cancer (2010)

IL, LIA, and IRMA detected increased CT concentrations in non-MTC patients and discriminated MTC from CKD patients in pentagastrin tests. PCT assessment may be helpful in the diagnostic work-up of increased CT concentrations in questionable clinical circumstances.
Forming of composite spars including interlayers of aligned, multiwall, carbon nanotubes: An experimental study (2016)

Carbon nanotubes offer the potential for improved or changed matrix properties, thereby enabling the creation of novel, multifunctional composite materials. By using highly aligned, multiwall, carbon nanotubes (MWCNT) with thermoset resins, good dispersion and distribution of nanotubes is obtained. To date, research has mainly focused on improving the growth process of the aligned MWCNTs, however little has been done on the processing of composites that include MWCNTs as interlayers in the stack. The aim of this work is to study how the aligned MWCNTs are affected within composite part forming. The study shows that MWCNTs are influenced by the shearing that occurs during forming, but still maintain their integrity. To some extent, the shear pattern observed in the MWCNTs after deformation provides an indication of deformation modes. However, the presence of MWCNTs also significantly influences the forming characteristics of the prepreg stack. POLYM. COMPOS., 39:181–191, 2018. © 2016 Society of Plastics Engineers
Um Reencontro com o Ocidente (2019)

Nosso sentimento de superioridade sobre um passado – que, queiramos ou nao, nos pertence – de  preconceitos, exclusoes e crimes, necessariamente nos torna mais livres e abertos do que nossos antepassados? E  esta a questao que o filosofo frances Alain Finkielkraut nos apresenta em A ingratidao, obra sobre a postura do homem atual frente a historia. Nascido em 1949, participante das rebelioes de maio de 1968, se na juventude  Finkielkraut erguia barricadas contra o status quo, na maturidade nao hesita em advogar a defesa de valores,  tradicoes ou instituicoes centrais da cultura ocidental. E o que se depreende da leitura de obras como A memoria  va e, sobretudo, A derrota do pensamento, ambas traduzidas para o portugues ha duas decadas1.(...)
Reverse Shoulder Arthroplasty with a New Convertible Short Stem: Preliminary 2- to 4-year Follow-up Results (2017)

Background The Grammont-style reverse shoulder arthroplasty (RSA) has demonstrated complications intrinsic to its design such as tuberosity fracture and scapular notching. A new short-stem press-fit humeral component with an onlay tray has been devised to avert these issues. We hypothesize that the clinical outcomes and rates of humeral complications of this new stem will be comparable to those of the traditional Grammont design and the lateralization obtained from the stem’s lower neck-shaft angle will decrease the rate of notching without creating instability. Methods We retrospectively evaluated 100 patients who underwent RSA with an onlay short-stem humeral component with a minimum follow-up of 2 years. Clinical outcomes as well as standard radiological examinations were documented pre- and postoperatively. Several correlations were analyzed. Results At mean 32.6-month follow-up, the cohort demonstrated a significant improvement in several outcomes: Constant score increased from 25.5 to 69.7 points, mean anterior elevation increased from 82.1° to 141.9°, external rotation from 5.6° to 25.1°, and internal rotation from sacrum to the L3 vertebral level. There was a 30% rate of stem malalignment and 37% rate of scapular notching, not associated with any adverse clinical outcomes. The overall rate of complications was 15%, of which scapular fractures were most common (5%). Conclusion Our short-term results suggest that the clinical outcomes and rates of humeral complications are similar to those reported for the Grammont RSA, demonstrating less scapular notching, but increased scapular stress fractures and potential subsidence of the prosthesis due to the metaphyseal press-fit require further investigations.
