Remembrance: Loel Shuler (2011)

If you find yourself searching for a way to describe the benefits of an early education in general semantics. I offer two words that sum it up for me: Loel Shuler. Loel died in January, just after her 89th birthday. The light of the world is a little dimmer for me. and rational thinking is just that much less common now. [ILLUSTRATION OMITTED] I first learned of Loel in April 2006 when she made her first post on the Institute's forum. She had stumbled on the forum somehow and rejoiced to find kindred souls. It didn't take me long to rejoice equally for having made her acquaintance. As a young woman of 17, she attended Olivet College, just too late for Korzybski's lectures, but in plenty of time to enjoy the benefits of Olivet's integration of general semantics into its curriculum. Loel particularly remembered Virginia Shull and how she effectively stripped away most of the unquestioned belief systems we'd brought with us to college, and cleared the way for us to start learning to learn. And learn she did. As she said in her introductory post, her 4 years under the Oxford Plan at Olivet shaped the person she became. Fortunately for me I took it all in and adapted it to my life without ever needing to categorize or put a name to it. You can read more about her education in a delightful reminiscence that appeared in the January 2007 issue of ETC. Loel participated in forum discussions over the next 3 years. Her posts ranged from brief questions to Jong posts about events from her life. From these posts, I learned about her book, Alaska, in the Wake of the North Star, which recounts her experiences during 3 months in 1950, traveling 11,000 miles by a supply ship along the coast of Alaska. Young, newly wed, and pregnant with her first child, she reveled in unexpected access to the villages and peoples of that time and place. Her memoir offers clear and gentle insights into a culture she came to love and honor, with a stated goal of reducing some common misperceptions about the vastness and variety that the name Alaska encompasses. After a divorce in 1961, Loel took her two young children back to the lower 48 to stay with her family in Michigan while she looked for work and a place to settle. Her daughter, Barbara Rose, recalls an arduous mid-winter car trip from Michigan to California, where they settled in Pacific Grove, allegedly because it offered a climate most like the Southeastern Alaska home they had left behind. …
Autoantibodies in iodide goitre and asthma. (1966)

Thyroid and gastric autoimmunity occurred more frequently in patients with iodide goitre and those with intrinsic asthma than in patients with extrinsic asthma or age- and sex-matched controls. It is suggested that iodide administration is more likely to lead to goitre and hypothyroidism in the intrinsic asthmatic group, where latent thyroid autoimmunity is common, by aggravation of an existing organification defect in the thyroid. Latent Graves' disease recognized by failure of suppression of the thyroid radioiodine uptake by triiodothyronine may also be responsible for some cases of iodide goitre.
Wireless Energy Transfer Through Non-Resonant Magnetic Coupling (2010)

We demonstrate by theoretical analysis and experimental verification that mid-range wireless energy transfer systems may take advantage of de-tuned coupling devices, without jeopardizing the energy transfer efficiency. Allowing for a modest de-tuning of the source coil, energy transfer systems could be properly designed to minimize undesired energy dissipation in the source coil when the power receiver is out of the range. Our basic observation paves the way for more flexible design and fabrication of non-resonant mid-range wireless energy transfer systems, thus potentially impacting practical implementations of wireless energy transfer.
Fabrication And Characterization Of Ti-Indiffused And Proton Exchange Waveguides In LiNbO 3 * (1984)

Two competing methods of optical waveguide formation in LiNb03 are the indiffusion of Ti and the exchange of Li with protons in an acidic solution. Numerous reports, both pro and con, have been made concerning waveguides fabricated using these two methods. In this paper, we would like to compare guided-wave Mach-Zehnder interferometric modulators fabricated using both of these methods. We will discuss the fabrication and testing of these devices including measurements of Vff, the voltage required to drive the modulator from its maximum output to its minimum output, the electrode capacitance, optical damageability, and waveguide bend and branch losses.
In vitro antimicrobial susceptibilities of 349 methicillin-resistant Staphylococcus aureus isolates from veterans. (1990)

Three hundred and forty-nine methicillin resistant Staphylococcus aureus (MRSA) isolates from veterans were tested (by disc agar diffusion) for their in vitro activity against 18 antimicrobial agents. At least 90% of the isolates were susceptible to bacitracin, nitrofurantoin, hydrogen peroxide, novobiocin, netilmicin and vancomycin. We feel that the aminoglycoside, netilmicin, might provide an alternative agent (to intravenously administered vancomycin) for treating multiply-antimicrobial resistant MRSA. In addition, hydrogen peroxide exhibited very good activity against the test isolates and may have some use as a topical agent for reduction of MRSA on skin and some mucous membranes. This study suggests that further evaluation of netilmicin and hydrogen peroxide (topical only) might be useful.
Partial Purification and Characterization of <i>Schistosoma Mansoni</i> Soluble Egg Antigen with Con A-Sepharose Chromatography (1979)

A crude preparation of Schistosoma mansoni soluble egg antigen (SEA) was subjected to affinity chromatography with concanavalin A (Con A) bound to Sepharose 4B. The resulting Con A fractions (bound and unbound) were characterized with sodium dodecyl sulfate (SDS) gel electrophoresis, immunoelectrophoresis, immunodiffusion, and lymphocyte blastogenesis techniques. In the fraction that did not bind to Con A there were at least two distinct antigens, and there were also at least two distinct antigens in the fractions that did bind to Con A. With SDS polyacrylamide gel electrophoresis, at least 20 distinct protein bands (Coomassie blue staining) and three glycoprotein bands (PAS reactive) were present in the unbound fractions from Con A chromatography. The bound fractions separated into at least six distinct glycoproteins with SDS electrophoresis. Although both the bound and unbound fractions contained precipitating antigens, only the bound fractions were capable of eliciting lymphocyte blastogenic responses.
Sulfonic-Functionalized Carbon Catalyst for Esterification of High Free Fatty Acid (2012)

We report synthesis and characteristics of sulfonic-functionalized carbon catalyst in this work. The carbon soild acid was prepared through the sulfonation of the incomplete carbonized mung bean vermicelli and was used as a solid acid catalyst for esterification of high free fatty acid. The catalyst (SBET = 18.1 m2/g, acid site density of 1.53 mmol H+/gcat) could exhibit high esterification activity in the reaction of oleic acid with methanol due to the efficient accessibility of bulky substrate molecule to sulfonic active site during the reaction. This environmentally benign and ecofriendly C-SO3H catalyst could be suited to esterify high FFA feedstocks reducing the production cost of biodiesel.

Asymmetric underwater acoustic communication using a time-reversal mirror (2002)

Phase conjugation using a time-reversal mirror is an array processing technique that allows accurate focusing of waves in poorly characterized media. When used for underwater communication, phase conjugation requires sending a probe signal from the desired focal point to the mirror, providing local templates for subsequent waveform generation that creates signals with low intersymbol interference at the focus. In spite of the simplicity of this method, and the potential reduction of receiver complexity that it can afford, frequent transmission of probes is undesirable because it forces the channel to remain almost idle during relatively long periods. In this paper, pulse shapes are estimated from incoming data blocks received at the mirror, thus eliminating the need for explicit channel probes. If a phase-conjugate array is used for bidirectional communication, pulse estimation can be an integral part of multichannel equalization algorithms, and its use in transmit mode entails virtually no increase in computational requirements. Simulation results illustrate significant performance improvements at low signal to noise ratios relative to direct pulse measurement, as averaging in estimation algorithms greatly limits the impact of noise. Formatting techniques that allow the mirror to change the data rate and pulse shape of the transmitted signal are also considered.
Novel Strategies to Improve the Anticancer Action of 5-Fluorouracil by Using Drug Delivery Systems (2008)

Because of the fundamental importance of new therapeutic routes for cancer treatment, a number of systems based on colloidal particles as vehicles for the delivery of the anticancer drug 5-fluorouracil have been devised. The target is always to provide the proper dose of the antitumor agent only at the desired locus of action, thus reducing the unwanted side effects. In this review, the main strategies and the more significant results in the development of 5-fluorouracil carriers for cancer treatment are discussed.
[Leu<sup>8</sup>]des‐Arg<sup>9</sup>‐bradykinin inhibits the angiogenic effect of bradykinin and interleukin‐1 in rats (1993)

1. Subcutaneous implantation of sterile polyether sponges in rats elicited a reproducible neovascular response over 14 days, as determined by measurements of relative sponge blood flow by a 133Xe clearance technique. The angiogenic response was verified by quantitation of haemoglobin contents and histological evaluation of vascularized sponges. 2. Daily administration of 1 nmol of bradykinin (BK) into the implants significantly enhanced the basal sponge-induced neovascularization, leading to higher 133Xe clearance values, increased haemoglobin contents, cellularity and vascularity. 3. When given alone, lower doses of BK (10 pmol) or recombinant human interleukin-1 alpha (IL-1 alpha, 0.3 pmol) produced no apparent effects on the basal sponge-induced angiogenesis. However, co-administration of these two peptides produced an angiogenic response similar to that elicited by 1 nmol of BK. 4. The BK/IL-1 alpha-induced neovascularization was abolished by the bradykinin B1 receptor antagonist, [Leu8]des-Arg9-BK (1 nmol day-1), but not by the B2 receptor antagonist Ac-D-Arg-[Hyp3, D-Phe7, Leu8]-BK (1 nmol day-1). 5. Thus, if such interaction between BK and IL-1 alpha contributes to the excessive neovascularization in chronic inflammatory diseases, the blockade of B1 receptors may provide an effective treatment.

Diverse Roles of Heparan Sulfate and Heparin in Wound Repair (2015)

Heparan sulfate (HS) and heparin (Hp) are linear polysaccharide chains composed of repeating (1→4) linked pyrosulfuric acid and 2-amino-2-deoxy glucopyranose (glucosamine) residue. Mentioned glycosaminoglycans chains are covalently O-linked to serine residues within the core proteins creating heparan sulfate/heparin proteoglycans (HSPG). The latter ones participate in many physiological and pathological phenomena impacting both the plethora of ligands such as cytokines, growth factors, and adhesion molecules and the variety of the ECM constituents. Moreover, HS/Hp determine the effective wound healing process. Initial growth of HS and Hp amount is pivotal during the early phase of tissue repair; however heparan sulfate and heparin also participate in further stages of tissue regeneration.
LASIK Interface Complications: Etiology, Management, and Outcomes (2012)

Differentiating between interface entities is critical to rapid appropriate diagnosis, treatment, and ultimate visual outcome. Although initial presentations may overlap significantly, the conditions can be readily distinguished with close follow-up, and most complications can resolve without significant visual sequelae when treated appropriately.

Design and Development of a Modular Platform for Remotely Testing DC Motors via the Internet (2011)

This thesis presents the design of a platform for testing DC motors over the Internet. The system allows customers to test multiple DC motors under the specific loading conditions of the real world application for which the motor is required. This provides more information than the motor performance charts alone, therefore allowing the user to make a more-informed decision. The architecture is divided into three subsystems: the Motor Test Platform, the Target Software Application and the Server Software Application. A proof-of-concept prototype was built using this architecture. This implementation was evaluated against benchmark tests to determine its capabilities as a simulation and evaluation tool. The positioning system performed well and was able to connect to different Test Motors with any proximal human operation. The positioning system did introduce some error compared to emulation done with manual coupling.

Modelling and Analysis of Temporal Preference Drifts Using A Component-Based Factorised Latent Approach (2018)

The changes in user preferences can originate from substantial reasons, like personality shift, or transient and circumstantial ones, like seasonal changes in item popularities. Disregarding these temporal drifts in modelling user preferences can result in unhelpful recommendations. Moreover, different temporal patterns can be associated with various preference domains, and preference components and their combinations. These components comprise preferences over features, preferences over feature values, conditional dependencies between features, socially-influenced preferences, and bias. For example, in the movies domain, the user can change his rating behaviour (bias shift), her preference for genre over language (feature preference shift), or start favouring drama over comedy (feature value preference shift). In this paper, we first propose a novel latent factor model to capture the domain-dependent component-specific temporal patterns in preferences. The component-based approach followed in modelling the aspects of preferences and their temporal effects enables us to arbitrarily switch components on and off. We evaluate the proposed method on three popular recommendation datasets and show that it significantly outperforms the most accurate state-of-the-art static models. The experiments also demonstrate the greater robustness and stability of the proposed dynamic model in comparison with the most successful models to date. We also analyse the temporal behaviour of different preference components and their combinations and show that the dynamic behaviour of preference components is highly dependent on the preference dataset and domain. Therefore, the results also highlight the importance of modelling temporal effects but also underline the advantages of a component-based architecture that is better suited to capture domain-specific balances in the contributions of the aspects.
The Acute Toxicity of Tris(Dimethylamino) Silane (1989)

The acute handling hazards of tris(dimethylamino)silane [TDMAS] were investigated. The acute male rat peroral LD50 (with 95% confidence limits) was 0.71 (0.51-0.97) ml/kg, and the acute male rabbit percutaneous LD50 was 0.57 (0.35-0.92) ml/kg. The liquid was severely irritating to the rabbit eye and skin, and the vapor severely irritating to the rat eye. The dynamically generated saturated vapor Lt50 in female rats was 12 (9.7-15) min. The effect of varying the atmospheric concentration of vapor from TDMAS on acute inhalation toxicity was investigated by passing ordinary moist air countercurrent to liquid TDMAS metered into a slightly heated glass tube. Based on nominal concentrations, the 4 hr-LC50 for vapor from TDMAS was 734 (603-893) ppm in female rats by this procedure. Stoichiometrically, this accords with toxicity due to liberation of dimethylamine (DMA) from TDMAS. In a subsequent study designed to assess the influence of relative humidity on vapor toxicity, nitrogen was passed over heated liquid TDMAS and the resultant atmosphere was introduced into the air intake duct of the inhalation exposure chamber. Gas chromatographically measured TDMAS concentrations (+/- SD) were 395 +/- 111, 127 +/- 25, 62 +/- 8 and 23 +/- 21 ppm; the corresponding DMA vapor concentrations were 112 +/- 171, 31 +/- 43, 10 +/- 6 and 26 +/- 44 ppm. The 4-hr LC50 (males and females) was 38 (34-43) ppm TDMAS vapor. Thus, TDMAS is of moderate acute peroral and percutaneous toxicity, a severe primary skin and eye irritant, an aspiration hazard, and of high intrinsic acute inhalation toxicity, but in moist air conditions lethal toxicity may be reduced and in such circumstances DMA may be a significant factor in toxicity.
PODER DISCRIMINATIVO DA POSIÇÃO DE CLASSIFICAÇÃO E DOS TESTES ESTATÍSTICOS NA SELEÇÃO DE GENÓTIPOS (1997)

Em trabalhos de melhoramento de plantas autógamas, na fase do chamado processo reducional, procura-se separar as melhores linhagens e eliminar as menos promissoras, reduzindo, assim, o número de seleções para plantio nos próximos ciclos. No presente trabalho, por processo de simulação, estudou-se o poder discriminativo da posição de classificação na separação das melhores linhagens nos ciclos intermediários do melhoramento de plantas. Consideraram-se, ao todo, três ciclos de seleção e três grupos, definidos pelo número de seleções a avaliar nos vários ciclos e pelos diferentes níveis de porcentagem de seleção. No terceiro ciclo, além da escolha pelo posto, utilizaram-se, também, os testes estatísticos de Student, Duncan, Dunnett (unilateral), SNK e Tukey. Para evitar escape dos melhores materiais, recomenda-se, em função dos resultados, que, quando as seleções forem muitas no primeiro ciclo, sejam alocadas em três ou quatro experimentos menores, sempre com a presença do controle, empregando 40% de indivíduos selecionados. Na etapa final da escolha das seleções, procurou-se, por simulação, estudar o poder discriminativo dos testes estatísticos utilizados no terceiro ciclo, para diferenças de 15, 12,5, 10, 7,5, 5 e 2,5%. Foram estudados experimentos individuais e grupos de experimentos em que o coeficiente de variação foi de 10, 15 e 20%. Na análise conjunta de grupos, considerando três experimentos e três anos, o poder discriminativo foi bem mais alto que nos individuais, para todos os testes, com valores iguais a 78% ou maiores, quando o C.V. foi de 10% e as diferenças, iguais ou maiores que 7,5%.
ConKMeL: a contextual knowledge management framework to support intelligent multimedia e-learning (2003)

Current multimedia information retrieval technologies to support e-learning can only provide basic low-level single type media retrieval services to common users, hence current e-learning services still lack intelligence and context-awareness. Much of the desired intelligent e-learning functionality needs further research and technical developments. The proposed framework ConKMel is expected to improve the current isolated learning information management status, by making the most use of related learning information, and enabling flexible knowledge communication and transfer between instructors and learners. To work with related existing e-learning content description standards and enable a semantic-based interactive learning environment, we explore a set of novel knowledge management techniques from a contextual knowledge engineering point of view. Based on knowledge communication model analysis, a contextual knowledge representation model is presented. Corresponding knowledge retrieval techniques are discussed afterwards to support modern learning approaches such as scenario-based learning.
The burden of malaria in pregnancy in malaria-endemic areas (2001)

Pregnant women in malarious areas may experience a variety of adverse consequences from malaria infection including maternal anemia, placental accumulation of parasites, low birth weight (LBW) from prematurity and intrauterine growth retardation (IUGR), fetal parasite exposure and congenital infection, and infant mortality (IM) linked to preterm-LBW and IUGR-LBW. We reviewed studies between 1985 and 2000 and summarized the malaria population attributable risk (PAR) that accounts for both the prevalence of the risk factors in the population and the magnitude of the associated risk for anemia, LBW, and IM. Consequences from anemia and human immunodeficiency virus infection in these studies were also considered. Population attributable risks were substantial: malaria was associated with anemia (PAR range = 3-15%), LBW (8-14%), preterm-LBW (8-36%), IUGR-LBW (13-70%), and IM (3-8%). Human immunodeficiency virus was associated with anemia (PAR range = 12-14%), LBW (11-38%), and direct transmission in 20-40% of newborns, with direct mortality consequences. Maternal anemia was associated with LBW (PAR range = 7-18%), and fetal anemia was associated with increased IM (PAR not available). We estimate that each year 75,000 to 200,000 infant deaths are associated with malaria infection in pregnancy. The failure to apply known effective antimalarial interventions through antenatal programs continues to contribute substantially to infant deaths globally.
