Liderança política e intelectual (2007)

28 nidas numa sala de aula da PUC-SP. Era um pequeno passo, mas importante. Falou-se da criacao de um Boletim, que foi a semente de nossa revista Psicologia Social e Sociedade. Mas foi uma articulacao a mais. De fora da PUC, apenas a Ângela Caniato e eu. E desde entao, nunca deixei de receber bilhetes seus articulando atividades e encontros. Em alguns encontros, eramos uma dezena. Mas ninguem consegue segurar o Zeitgeist, o espirito. No encontro da ABRAPSO em Belo Horizonte, ja houve um crescimento enorme. E a Abrapso faz hoje encontros de mais de 3.000 pessoas. Mas precisa coragem e pertinacia. Cansei de ver Silvia sentada numa sala de aula, nesses encontros, com um pequeno grupo de pessoas, discutindo, falando, incentivando. Para todos tinha um carinho. E como isso frutificou. 3. Termino ressaltando um ultimo ponto que considero central em Silvia, o que eu chamaria de sua “teoria do conhecimento”. Nisso tambem vi como ela cresceu. Vendo sua producao, percebe-se que Silvia foi compreendendo que o saber, o conhecimento, e muito mais do que um conhecimento cognitivo, logico. Pelo contrario, ele e polifasico, elastico, multiplo. Inclui a dimensao da emocao, da paixao e, principalmente, da acao. Costumava dizer que a psicologia comecou a se interessar pelo pensar, passando ao falar, depois ao agir e que com dificuldade chegava ao sentir. O livro Psicologia das Emocoes lida com essa problematica. Ate a decada de 1980, o conhecimento reconhecido como valido nas academias era nossa heranca cartesiana, um conhecimento racional e logico e individual. Tudo o resto eram crencas, supersticoes, mitos, etc. Ora, o saber popular, o saber do senso comum, por estar impregnado
Improving Carrier Lifetime of Au-Hyperdoped Si by Material Tailoring (2020)

Enhanced solar spectrum utilization is proposed to be achieved by intermediate band photovoltaics. Hyperdoping is a viable method to fabricate such materials by introducing large concentrations of dopants. We investigate various hyperdoping and etching methods followed by surface passivation to engineer materials with longer charge carrier lifetimes. Time resolved terahertz spectroscopy technique is applied to evaluate the decay dynamics in order to identify the optimum material candidate.
Cost and Performance Report for a Zero Valent Iron (ZVI) Treatability Study at Naval Air Station North Island (2008)

Abstract : A zero-valent iron (ZVI) pilot treatability study was conducted for the treatment of chlorinated organics (primarily trichlorothylene) in groundwater at Operable Unit 20 at Naval Air Station North Island in 2006. From August 22, 2006 through September 7, 2006, Ferox injection (pressurized injection of water and ZVI powder slurry) was implemented at five locations, between approximately 30 and 60 ft below ground surface. This report summarized the cost and performance data from this treatability study.
Polarization state-dependent stress effect on the dielectric properties of lead zirconate titanite thin films (2006)

We performed a bending experiment on a thin Pb(Zr,Ti)O3 (PZT) film prepared by chemical solution deposition. The changes of dielectric constant under stress were measured upon sweeping the electric field applied across the PZT film. It was found that depending on the strength of the electric field and thereby on the polarization state of the ferroelectric film, stress acts as a promoter as well as an obstructor for the polarization. An explanation for the abnormal dielectric behavior is given based on the domain wall motion and the reorientation of polarization state.
Clinical Aspects of Gastric Cancer and Helicobacter pylori– Screening, Prevention, and Treatment (2010)

Gastric cancer still represents a global health care burden, and in the absence of strategies implemented for early detection, the disease continues to have a dismal prognosis. Patients presenting with clinical manifestations of gastric cancer have limited options for cure. Thus, early detection and prevention play a key role in the fight against gastric cancer. Serologic-based test methods have the potential to detect a subset of patients at high risk of gastric cancer that require a close clinical and endoscopic follow-up. More data have been produced to support Helicobacter pylori eradication as an efficient strategy to prevent gastric cancer. Treatment options for patients with an advanced disease are still limited, but the introduction of new agents opens a more optimistic perspective for the future.

Changes of Anion Exchange Membrane Properties During Chemical Degradation (2020)

Water content plays a major role in the properties of anion-exchange membranes (AEMs) and, therefore, in the AEM fuel cell (AEMFC) performance and performance stability. Characterization of AEMs during membrane degradation is critical in order to understand the membrane behavior during fuel cell operation time. In spite of its importance, the relationship between different membrane properties during chemical degradation has yet to be investigated. In this study, we measure the changes in AEM properties—in particular, ion exchange capacity (IEC), water uptake (WU) and conductivity—during membrane chemical degradation in alkaline medium. To the best of our knowledge, this is the first time this kind of data has been investigated. While all the properties change during AEM degradation, results indicate that membrane WU decreases linearly with decreasing IEC; however, AEM ion-conductivity shows a sigmoidal-like shape relationship with IEC. We introduce a simple model to explain these effects.
Module-Based Outcome Prediction Using Breast Cancer (2007)

Background. The availability of large collections of microarray datasets (compendia), or knowledge about grouping of genes into pathways (gene sets), is typically not exploited when training predictors of disease outcome. These can be useful since a compendium increases the number of samples, while gene sets reduce the size of the feature space. This should be favorable from a machine learning perspective and result in more robust predictors. Methodology. We extracted modules of regulated genes from gene sets, and compendia. Through supervised analysis, we constructed predictors which employ modules predictive of breast cancer outcome. To validate these predictors we applied them to independent data, from the same institution (intra-dataset), and other institutions (inter-dataset). Conclusions. We show that modules derived from single breast cancer datasets achieve better performance on the validation data compared to gene-based predictors. We also show that there is a trend in compendium specificity and predictive performance: modules derived from a single breast cancer dataset, and a breast cancer specific compendium perform better compared to those derived from a human cancer compendium. Additionally, the module-based predictor provides a much richer insight into the underlying biology. Frequently selected gene sets are associated with processes such as cell cycle, E2F regulation, DNA damage response, proteasome and glycolysis. We analyzed two modules related to cell cycle, and the OCT1 transcription factor, respectively. On an individual basis, these modules provide a significant separation in survival subgroups on the training and independent validation data.

Coffee, tea, tobacco, and cancer of the large bowel. (1995)

The impact of tobacco use and coffee and tea intake on the risk of colorectal cancer is unclear. Previous research has suggested that coffee may be protective against these cancers, and investigation regarding tea or cigarette smoking has yielded inconsistent results. To clarify these issues, we evaluated coffee and tea intake and tobacco smoking as risk factors for cancer of the colon and rectum in a population-based case-control study from Stockholm, Sweden. Cases were ascertained from the regional cancer registry, and controls identified through population registers. Subjects completed a questionnaire requesting information regarding foods and beverages consumed, exercise, tobacco use, and personal characteristics. Logistic regression modelling was used to compute odds ratios. A total of 352 cases of colon cancer, 217 cases of rectal cancer, and 512 controls took part. High coffee intake was negatively associated with the risk of colon cancer: the odds ratio for those drinking 6 or more cups per day was 0.55 (95% confidence interval, 0.31-0.96) compared to those drinking one or fewer. There was no association with rectal cancer. For tea, the associations were the opposite: there was no association with colon cancer risk, but the odds ratio for rectal cancer was 0.56 (95% confidence interval, 0.34-0.90) for those drinking 2 or more cups per day compared with those drinking none. Smokers of 11 or more cigarettes per day had a 20 to 30% reduction in the risk of colon and rectal cancer, but these findings were consistent with chance. There was no association of long-term cigarette smoking with risk.
Oxygen incorporation during fabrication of substrate CdTe photovoltaic devices (2012)

Recently, CdTe photovoltaic (PV) devices fabricated in the nonstandard substrate configuration have attracted increasing interest because of their potential compatibility with flexible substrates such as metal foils and polymer films. This compatibility could lead to the suitability of CdTe for roll-to-roll processing and building-integrated PV. Currently, however, the efficiencies of substrate CdTe devices reported in the literature are significantly lower (~6%-8%) than those of high-performance superstrate devices (~17%) because of significantly lower open-circuit voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> ) and fill factor (FF). In our recent device development efforts, we have found that processing parameters required to fabricate high-efficiency substrate CdTe PV devices differ from those necessary for traditional superstrate CdTe devices. Here, we investigate how oxygen incorporation in the CdTe deposition, CdCl <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> heat treatment, CdS deposition, and post-deposition heat treatment affect device characteristics through their effects on the junction. By adjusting whether oxygen is incorporated during these processing steps, we have achieved V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> values greater than 860 mV and efficiencies greater than 10%.
Electrical power factor for a single crystal tonpilz versus a plate with matching layers (2021)

For underwater transducers mounted on small platforms, reactive electrical power can constitute a main restriction on the usable frequency range. The frequency range in which the amount of reactive power is acceptable can be increased by increasing the electromechanical coupling coefficient of the active material. However, to avoid large electrical power factor ripple, the transducer design must also have a low mechanical quality factor, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{m}$</tex> . A ferroelectric single crystal can have electromechanical coupling coefficient <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$k=0.9$</tex> . The optimum <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{m}$</tex> is then as low as 0.6, which is challenging to achieve. We investigated this challenge for a tonpilz design, by calculating <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{m}$</tex> for different combinations of head masses and tonpilz stiffnesses, and by calculating the stiffness to density ratio required in the head material to avoid flexural resonances. The effective coupling coefficient of a real transducer is reduced compared to the material coupling coefficient, and in many applications some power factor ripple can be accepted. Both factors relax the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{m}$</tex> requirement. We calculated the power factor of a tonpilz design with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$k=0.82$</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{m}=1.9$</tex> , and showed that the power factor ripple is smaller than 0.2 in a frequency band that is 150 % wide relative to the resonance frequency. The frequency independent matching inherent in the tonpilz gives this design an advantage regarding power factor ripple, and this can weigh up for a large <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q_{m}$</tex> . We showed this by comparing the tonpilz to an air-backed composite plate. Like the tonpilz, the composite plate had <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$k=0.82$</tex> , but it was matched to water by two conventional acoustic matching layers. Compared to the tonpilz, the composite design had a larger distance between the −3dB points of the acoustic power. Beyond these points, the acoustic power was however falling off more rapidly, resulting in an electrical power factor ripple of nearly 0.5.
Crystal Engineering with Alicyclic β-Amino Acids:  Construction of Hydrogen-Bonded Bilayers (2004)

The crystal structures of four homologous cis-alicyclic β-amino acids present a new recurring layer pattern of hydrogen bonds. This pattern was derived from two one-dimensional patterns observed in related alicyclic 2-hydroxycarboxylic acid structures. Its robustness is demonstrated by the isostructurality of the four crystals. The hydrogen bonds arrange the molecules in bilayers in the solid phase. The pattern was stressed by variations of the molecules, i.e., by the introduction of a double bond, by the change between stereoisomers, and by the replacement of the simple alicyclic ring with a bicyclic one. These variations gradually weaken the correspondence of the actual structure to the original design.
Antiplatelet and Thermally Responsive Poly(N-isopropylacrylamide) Surface with Nanoscale Topography (2009)

Nanoscale topography was constructed on a thermally responsive poly(N-isopropylacrylamide) (PNIPAAm) surface by grafting the polymer from silicon nanowire arrays via surface-initiated atom transfer radical polymerization. The as-prepared surface showed largely reduced platelet adhesion in vitro both below and above the lower critical solution temperature (LCST) of PNIPAAm ( approximately 32 degrees C), while a smooth PNIPAAm surface exhibited antiadhesion to platelets only below the LCST. Contact angle and adhesive force measurements on oil droplets (1,2-dichloroethane) in water demonstrated that the nanoscale topography kept a relatively high ratio of water content on the as-prepared surface and played a key role in largely reducing the adhesion of platelets; however, this effect did not exist on the smooth PNIPAAm surface. The results can be used to extend the applications of PNIPAAm in the fields of biomaterials and biomedicine under human physiological temperature and provide a new strategy for fabricating other blood-compatible materials.
Improved Treatment of MT-3 Breast Cancer and Brain Metastases in a Mouse Xenograft by LRP-Targeted Oxaliplatin Liposomes (2015)

The anti-cancer drug oxaliplatin (OxP) has rarely been used to treat breast carcinoma, as it cannot cross the BBB to treat the frequently subsequent brain metastases. Here, we encapsulated OxP in liposomes prepared to reduce side effects and to simultaneously treat primary tumor and brain metastasis. The angiopep LRP-receptor ligand was bound to the vesicular surface for targeting. Targeted and non-targeted OxP liposomes were tested in vitro (binding, uptake, and transcytosis) and in vivo. Liposomes contained 0.65 mg OxP/mL, their mean diameter was 165 nm, and they released 50% of OxP within 8 days at 4 degrees C and within 22 h at 36 degrees C. MDCK cells were used for uptake and transcytosis quantification. Compared to non-targeted liposomes, targeted liposomes showed 12-fold greater uptake, and 2.25-fold higher transcytosis. In vivo efficacy was tested using human MT-3 breast cancer cells transplanted subcutaneously and intracerebrally into female nude mice, and tumor growth inhibition was measured. OxP was injected (6 mg OxP/kg) four times. The best results were obtained with targeted liposomes (T/C: 21% for subcutaneous and 50% for intracerebral). OxP liposomes with a fluid membrane all inhibited MT-3 tumors significantly better than free OxP, with no significant difference between targeted and non-targeted liposomes. The therapeutic effect was accompanied with strong leukopenia and mild thrombocytopenia with all formulations. The newly developed OxP liposomes significantly improved the treatment of subcutaneously and intracerebrally growing breast cancer, but the targeted angiopep-equipped liposomes showed no superior effect in vivo.
<title>Stereometric Quality Of Scanning Electron Microscope Imagery</title> (1971)

The recent development of the scanning electron microscope (SEM) has added a new dimension to the field of microscopy. The SEM produces an image having considerable depth of focus; for example, approximately 400 times that of a light microscope at equivalent magnifications. It can be operated continuously between magnifications of 20 and 100,000X with a resolution of approximately 100 A.© (1971) COPYRIGHT SPIE--The International Society for Optical Engineering.

Decomposition of Tetramethylammonium Cyanosulfite and Crystal Structures of [(CH3)4N]+HSO4- � SO2 and [(CH3)4N+]2S2O72- �2SO2 Tetramethylammonium cyanosulfite decomposes in SO2 bei -70 °C to give HCN, [(CH3)4N]+HSO4- � SO2 and [(CH3)4N+]2S2O72- �2SO2.

Five colour variants of bright luminescent protein for real-time multicolour bioimaging (2016)

Luminescence imaging has gained attention as a promising bio-imaging modality in situations where fluorescence imaging cannot be applied. However, wider application to multicolour and dynamic imaging is limited by the lack of bright luminescent proteins with emissions across the visible spectrum. Here we report five new spectral variants of the bright luminescent protein, enhanced Nano-lantern (eNL), made by concatenation of the brightest luciferase, NanoLuc, with various colour hues of fluorescent proteins. eNLs allow five-colour live-cell imaging, as well as detection of single protein complexes and even single molecules. We also develop an eNL-based Ca<sup>2+</sup> indicator with a 500% signal change, which can image spontaneous Ca<sup>2+</sup> dynamics in cardiomyocyte and neural cell models. These eNL probes facilitate not only multicolour imaging in living cells but also sensitive imaging of a wide repertoire of proteins, even at very low expression levels.

A Quantitative Measure of Memory Reference Regularity (2001)

The memory performance of applications on existing architectures depends significantly on hardware features like prefetching and caching that exploit the locality of the memory accesses. The principle of locality has guided the design of many key micro-architectural features, including cache hierarchies, TLBs, and branch predictors. Quantitative measures of spatial and temporal locality have been useful for predicting the performance of memory hierarchy components. Unfortunately, the concept of locality is constrained to capturing memory access patterns characterized by proximity, while sophisticated memory systems are capable of exploiting other predictable access patterns. Here, we define the concepts of spatial and temporal regularity, and introduce a measure of spatial access regularity to quantify some of this predictability in access patterns. We present an efficient online algorithm to dynamically determine the spatial access regularity in an application's memory references, and demonstrate its use on a set of regular and irregular codes. We find that the use of our algorithm, with its associated overhead of trace generation, slows typical applications by a factor of 50-200, which is at least an order of magnitude better than traditional full trace generation approaches. Our approach can be applied to the characterization of program access patterns and in the implementation of sophisticated, software-assisted prefetching mechanisms, and its inherently parallel nature makes it well suited for use with multi-threaded programs.
