Access to Information and the Adoption of Hybrid Maize: Evidence from China's Poor Areas (2004)

This paper investigated the role of farmers' access to information in a farm household's decisions of whether or not to adopt hybrid maize and the amount to adopt using data collected in a poor region of China. The empirical results suggest that increased availability of medium and more frequent extension visits would lead more farmers to adopt the hybrid maize. It is also found that, once adoption is realized, more frequent extension visits to the adopters will be vital to influence farmers to allocate more of their maize area to hybrid maize. The paper also demonstrate the adoption of new technology in the poor areas may well be different from that in the rich areas.
<title>Phase-structure transitions of glass-ceramics under IR-laser action: main peculiarities</title> (2006)

The main peculiarities of laser-induced structure modification in TiO<sub>2</sub>-SiO<sub>2</sub> based glass-ceramics are experimentally investigated and discussed. The rates of such phase-structure transitions under laser heating are about 10<sup>2</sup>-10<sup>3</sup> times higher than under conventional heating in a furnace. The laser technology of structural modification in glass-ceramics is very attractive for development and fabrication of new microcomponents and devices.
The bookmark and the compass: orientation tools for hypertext users (1988)

The power of hypertext stems chiefly from the complex networks of conceptual links which hypertext documents can render explicit. This paper describes an array of orientation tools which help readers to choose a course through a complex information network without undue confusion or discomfort, while retaining the excitement and spontaneity users often experience when exploring complex information environments.

P‐131: New Model of Image Sticking Mechanism on Long Period AC Field of IPS Mode (2009)

Abstract It is known that AC electric field to drive IPS mode of liquid crystal display (LCD) causes reduction of the contrast after long period of display operation. Our results are presented in this paper on a base of a model of interaction between surface of PI alignment film and LC molecules. We conclude that the surface rheology of PI alignment film is one of the most important factors for the contrast reduction phenomenon.
Protein C Antigen Levels in Major Abdominal Surgery: Relationships to Deep Vein Thrombosis, Malignancy and Treatment with Stanozolol (1985)

Activated protein C is a potent inhibitor of coagulation, and familial protein C deficiency has been associated with recurrent venous thrombosis. We have investigated protein C antigen levels in patients undergoing major elective abdominal surgery, to determine their relationships to postoperative deep vein thrombosis (DVT), malignancy, and preoperative treatment with intramuscular or oral stanozolol. Preoperative and postoperative protein C levels were not significantly different in patients with and without DVT (detected by 125I-fibrinogen leg scans), nor in patients with and without malignancy. In a placebo group (n = 26), a significant fall in protein C was maximal on the first postoperative day and persisted for 7 days. In a group given intramuscular stanozolol, 50 mg on the preoperative day (n = 23) stanozolol shortened the duration of the postoperative fall in protein C, but did not prevent DVT. In a group given oral stanozolol, 10 mg/day for 2 weeks before and 1 week after operation (n = 11), stanozolol significantly increased protein C levels prior to surgery, hence maintaining protein C at pretreatment levels after surgery. The effect of this regimen on the incidence of DVT is under study.
Molecular cloning of the antibacterial protein of the giant African snail, <i>Achatina fulica</i> Férussac (1992)

An expression cDNA library was constructed with poly(A)-rich RNA extracted from the collar of the giant African snail, Achatina fulica Férussac. A 1.9-kbp cDNA clone encoding a precursor of antibacterial glycoprotein of the snail, achacin, was isolated from the cDNA expression library. The cDNA sequence contains an open reading frame with 1593-nucleotide residues. The deduced amino acid sequence of this achacin precursor starts with a 29-residue leader peptide followed by a 502-residue mature peptide (56 kDa) with four possible N-glycosylation sites, Asn-Xaa-Ser or Asn-Xaa-Thr. The Northern-blot analysis proved that the achacin precursor was specifically expressed in the tissue of snail collar and processed to mature achacin. cDNA inserts encoding achacin precursor were subcloned into expression plasmids. Three kinds of expressed polypeptides were cross-reacted with rabbit antiserum raised against achacin. The largest polypeptide (M(r) 63,000) should be the achacin precursor.
Optimal binary switch codes with small query size (2015)

In this paper, we study a construction of binary switch codes. A switch code is a code such that a multi-set request of information symbols can be simultaneously recovered from disjoint sets of codeword symbols. Our construction is optimal in the sense that it has the smallest codeword length given its average encoding degree, which is logarithmic in the code dimension. Moreover, the number of queries needed to recover any information symbol in the request is at most 2. As a result, our construction is the first family of switch codes with low encoding and decoding complexity.
An analytical model for predicting the residual life of an IC and design of residual-life meter (2017)

Integrated Circuits age differently based on their operating conditions. A device that operates under high voltage or temperature stress ages faster. In many safety critical applications, such as in automotive systems, avionics and cyber-physical infrastructure, users would like to know the residual life of its components to ensure timely replacements. This motivates design of a residual-life meter (RLM). A residual-life meter may also prevent re-entry of recycled ICs from discarded systems into the supply chain as new parts - a problem that is deemed as a threat to critical infrastructure. Design of lifespan meter requires analytical models for predicting residual life of an IC based on its history of operating conditions. A major contribution of this paper is development of an analytical model for determining the residual life of an IC. There are a number of aging mechanisms that impact the lifetime of an IC such as oxide breakdown, hot electron effect, negative bias temperature instability, electromigration and others. While the proposed approach is general, for the purpose of illustration, in this study, we focus on residual life modeling based on Electromigration. The model relies on current temperature as input which is obtained from on-chip temperature sensor. This obviates any need for workload characterization. Next, this paper presents three alternative circuit implementations of the proposed residual-life meter. Results show that an RLM can be implemented at an area of ~ 350μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , and frequency of 3.3 GHz in CMOS 45nm technology. The RLM relies on non-volatile storage for data retention and is immune to power shut-offs. Prior aging sensors rely on sample size of single path, which is statistically insignificant. This work provides an alternative approach of analytical modeling, which is statistically comprehensive while retaining the simplicity of a single meter design.
Isolation and puriﬁcation of the hypoglycaemic principle present in <i>Capsicum frutescens</i> (2004)

Capsicum frutescens has been used to treat diabetes mellitus by traditional healers in Jamaica. Purification experiments employing thin layer chromatography (TLC) and high performance liquid chromatography led to the extraction of the active principle, capsaicin. Purified capsaicin caused a decrease in blood glucose levels to 4.91 +/- 0.52 (n = 6) mmol/dL versus 6.40 +/- 0.13 mmol/dL (n = 6) for the control (p < 0.05) at 2.5 h in an OGTT in dogs. There was a concomitant elevation in plasma insulin levels (p < 0.05). In conclusion, it can be stated that capsaicin is the major constituent of Capsicum frutescens that is responsible for the hypoglycaemic episodes seen in the dogs. It is also apparent that the latter is mediated by insulin release.
The F‐Actin Content of Multiple Myeloma Cells as a Measure of Their Migration (2002)

One of the main characteristics of multiple myeloma (MM) cells is their specific homing and growth in the bone marrow (BM). For their homing, MM cells need chemotactic signals to be attracted towards the BM and to be activated. Profound knowledge of the different chemokines for MM cells and their signal transduction pathways is necessary to interfere in this process. We studied here an extra possible tool for the investigation of the different chemokines and their pathways. The 5T experimental mouse model was used to investigate the migration of MM cells towards BM stromal cells. We studied the changes of the F-actin content in the 5TMM cells in the presence of BM stromal cell conditioned medium and we correlated this with their migratory capacity. F-actin became polarized when the cells were migrating, in contrast to nonmigrating cells. This polarization could not only be seen by fluorescence and confocal laser scanning microscopy, but also could be quantified by fluorometry and flow cytometry. The correlation between the F-actin content of the MM cells and their migration capacity thus makes its quantification a useful tool in studying their migratory behavior.
Xenobiotic Stress Induces Hepatomegaly and Liver Tumors via the Nuclear Receptor Constitutive Androstane Receptor (2005)

The constitutive androstane receptor (CAR, NR1I3) is a central regulator of xenobiotic metabolism. CAR activation induces hepatic expression of detoxification enzymes and transporters and increases liver size. Here we show that CAR-mediated hepatomegaly is a transient, adaptive response to acute xenobiotic stress. In contrast, chronic CAR activation results in hepatocarcinogenesis. In both acute and chronic xenobiotic responses, hepatocyte DNA replication is increased and apoptosis is decreased. These effects are absent in CAR null mice, which are completely resistant to tumorigenic effects of chronic xenobiotic stress. In the acute response, direct up-regulation of Mdm2 expression by CAR contributes to both increased DNA replication and inhibition of p53-mediated apoptosis. These results demonstrate an essential role for CAR in regulating both liver homeostasis and tumorigenesis in response to xenobiotic stresses, and they also identify a specific molecular mechanism linking chronic environmental stress and tumor formation.
Catalysis by Organic Solids. Stereoselective Diels−Alder Reactions Promoted by Microporous Molecular Crystals Having an Extensive Hydrogen-Bonded Network (1997)

Anthracenebisresorcinol derivative 1 as an organic network material shows a novel catalysis in the solid state for the acrolein−cyclohexadiene Diels−Alder reaction. The suggested mechanism involves a catalytic cycle composed of sorption of the reactants in the cavities of polycrystalline host 1, preorganized intracavity reaction, and desorption of the product. The host also promotes stereoselective intracavity reactions for alkyl acrylates and cyclohexadiene but, in this case, not in a catalytic manner. Relevance of the present system as a functional organic analog of zeolites is discussed in light of the kinetics of respective elementary processes and the effects of pulverization of the catalyst thereupon as well as X-ray crystal structures.
Inhibition of SIRT1 Impairs the Accumulation and Transcriptional Activity of HIF-1α Protein under Hypoxic Conditions (2012)

Sirtuins and hypoxia-inducible transcription factors (HIF) have well-established roles in regulating cellular responses to metabolic and oxidative stress. Recent reports have linked these two protein families by demonstrating that sirtuins can regulate the activity of HIF-1 and HIF-2. Here we investigated the role of SIRT1, a NAD+-dependent deacetylase, in the regulation of HIF-1 activity in hypoxic conditions. Our results show that in hepatocellular carcinoma (HCC) cell lines, hypoxia did not alter SIRT1 mRNA or protein expression, whereas it predictably led to the accumulation of HIF-1α and the up-regulation of its target genes. In hypoxic models in vitro and in in vivo models of systemic hypoxia and xenograft tumor growth, knockdown of SIRT1 protein with shRNA or inhibition of its activity with small molecule inhibitors impaired the accumulation of HIF-1α protein and the transcriptional increase of its target genes. In addition, endogenous SIRT1 and HIF-1α proteins co-immunoprecipitated and loss of SIRT1 activity led to a hyperacetylation of HIF-1α. Taken together, our data suggest that HIF-1α and SIRT1 proteins interact in HCC cells and that HIF-1α is a target of SIRT1 deacetylase activity. Moreover, SIRT1 is necessary for HIF-1α protein accumulation and activation of HIF-1 target genes under hypoxic conditions.
An investigation about the effect of oxazolidine on modified valonia extract tanning (2008)

This study is aimed at combining the usage of valonia and modified valonia extracts with oxazolidine to obtain an increase in hydrothermal stability, and thus to develop tanning efficiency and to produce leathers that have better properties then the ones tanned with valonia extract only. Natural and three modified valonia extracts and oxazolidine were used as tanning materials. Skin samples were divided into two groups. In group A, valonia extracts were used as tanning materials and oxazolidine as retanning agent. Group A was divided into 4 subgroups according to the used extract type. Each subgroup was also separated into four lots according to the oxazolidine percentages used. Group B where oxazolidine was used as pretanning while valonia extracts as tanning agents, was divided into three subgroups according of oxazolidine usage. Each subgroup had four lots according to the used extracts. General means of Shrinkage Temperatures (Ts) for natural extract, group A and B were found as 65.66, 78.62 and 83.42 o C, respectively, indicating that the oxazolidine pretanning followed by valonia retanning provides better tanning efficiency. On the base of the unique experiment, 4% oxazolidine and 20% least modified vegetable tannin combination gave the best result.

아더 피어선의 영성 (2020)

21세기에 접어들어 한국교회 뿐 아니라 세계의 모든 교회가 영성이라는 주제에 큰 관심을 가지고 있다. 오히려 교회뿐 아니라 타 종교, 그리고 신학뿐 아니라 타 학문이 이 영성이라는 주제에 근자에 오히려 더 큰 관심을 가지게 되었다고 하는 것이 더 정확한 표현일 것이다. 그렇기 때문에 ‘영성’이라는 말은 좋게 표현하면 매우 포괄적인 의미를 가졌다고 할 수 있다. 하지만 다른 말로하면, 이 ‘영성’이라는 것에 대해서 여러 학문과 종교 그리고 심지어 기독교 내에서 조차도 정의가 서로 각기 다르기 때문에, 이것은 그 어디에도 적용가능 하지만, 막상 그 본질은 알 수 없는 그 어떤 것이 되고 말았다. 매우 혼잡한 개념의 ‘영성’ 이해 때문에, 기독교 내에서도 ‘영성’을 정적주의에 국한 시키거나 혹은 신비주의로 빠지는 결과를 낳게 된 것이다.
이러한 상황 속에서 피어선의 신학과 영성은 우리에게 신비주의나 정적주의 그 어디에도 빠지지 않는 중도의 영성을 가르쳐준다. 피어선의 신학은 ‘이것 혹은 저것’이 아닌 ‘이것과 저것 사이’의 진리를 붙잡으면서 양쪽 어디에도 치우치지 않음과 동시에 둘 모두를 말한다. 그러므로 피어선의 영성은 오늘날의 영성의 올바른 방향을 잡아줄 뿐 아니라 그리스도인으로서의 올바른 영성으로 인한 축복을 가르쳐준다.
따라서 본 논문에서 필자는 먼저 영성을 나름대로 정의해볼 것이다. 그렇게 함으로써 진정한 영성은 바로 기독교 영성임을 규명할 것이다. 그런 다음 영성에 대한 다소 극단적인 이해 형태인 교의학적 정적주의와 은사주의적 신비주의 이해를 비판적으로 다룰 것이다. 그런 다음 피어선의 영성을 통해 올바른 기독교 영성을 제시할 것이다. 규명하려는 것은 영성은 교의학이나 은사주의 혹은 삶 그 어느 하나에만 국한 된 것이 아닌, 그렇다고 지나치게 넓은 범위도 아닌 하나님의 자녀로서 그분의 유업에 참예하는 그리스도를 닮아가는 그리스도인의 거룩한 삶임을 피어선의 영성을 통해 밝히는 것이다.
Treatment of Severe Systemic Inflammatory Response Syndrome and Sepsis With a Novel Bradykinin Antagonist, Deltibant (CP-0127)<subtitle>Results of a Randomized, Double-blind, Placebo-Controlled Trial</subtitle> (1997)

<h3>Objective.</h3> —To test the effect of a novel bradykinin antagonist, deltibant (CP-0127), on survival, organ dysfunction, and other outcomes in patients with the systemic inflammatory response syndrome (SIRS) and presumed sepsis. <h3>Design.</h3> —Multicenter, randomized, placebo-controlled, double-blind, parallel, dose-ranging trial. Follow-up for 28 days or until death. <h3>Setting.</h3> —A total of 47 US referral hospitals. <h3>Patients.</h3> —A total of 504 patients with SIRS and documented evidence of infection plus either hypotension or dysfunction of 2 organ systems. <h3>Interventions.</h3> —Three-day continuous intravenous infusion of either placebo or 1 of 3 doses (0.3,1.0, or 3.0 μg.kg-1.man-1) of deltibant. Concurrent therapy at the discretion of the treating physician. <h3>Main Outcome Measure.</h3> —Risk-adjusted, 28-day, log-normal intent-to-treat survival analysis. Risk adjustment was performed using a study-specific risk model derived from the APACHE III database. <h3>Results.</h3> —Deltibant had no significant effect on risk-adjusted 28-day survival. In a posthoc analysis, risk-adjusted 7-day survival showed a nonsignificant trend toward improvement (<i>P</i>=.09). The 28-day risk-adjusted survival in the prospectively defined subset of patients with gram-negative infections showed a statistically significant improvement (<i>P</i>=.005). <h3>Conclusions.</h3> —Deltibant may have some effect on survival in patients with SIRS and gram-negative sepsis; however, additional studies would be required to prove this.
Aldosteronism in Man (1963)

STUDIES upon the mechanism by which normal<sup>1</sup>men acclimatize to heat, carried out in our laboratory between 1943 and 1946, gave information which was responsible for the recognition of primary aldosteronism as a clinical entity. This included evidence that: In the process of heat adaptation an endogenous desoxycorticosterone-like steroid is produced in large amounts as reflected in decreasing concentrations of sodium in thermal sweat. Administered desoxycorticosterone produced the same effects. Increased steroidal activity of this type continued in the absence of evidence of increased activity of the adrenal cortex in other respects. The ability of the acclimatizing man to maneuver himself into a condition of positive sodium balance, despite large sweat volumes, was accomplished by an integrated response of the kidney and sweat glands with respect to salt conservation, and that this was mediated by increased activity of the endogenous desoxycorticosteronelike steroid.

Mechanism of Gm degradation and comparison of Vt instability and reliability of HfO/sub 2/, HfSiO/sub x/ and HfAlO/sub x/ gate dielectrics with 80 nm poly-Si gate CMOS (2005)

To achieve a lower gate leakage in high speed devices at the same equivalent oxide thickness, a major thrust is to replace the SiO/sub 2/ with a thicker dielectric that has a higher dielectric constant. Recently, there has been much interest in hafnium dioxide as a potential high-k gate dielectric as presented in E. P Gusev et a. (2001), B. Barlage et al. (2001), G. Wilk et al. (2001), C. Hobbs et al. (2001), W. Zhu et al. (2001), W. Qi et al. (2000) and B. Lee et al. (1999) due to its high permittivity. However, the polycrystalline microstructure may be undesirable. In order to increase the crystallization temperature, SiO/sub 2/ or Al/sub 2/O/sub 3/ are added to HfO/sub 2/ to form Hf silicates atid Hf aluminates. A systematic study to compare the device characteristics of these three major candidates is needed. In this work, we have compared them in terms of the key challenges of high-K devices such as Gm degradation, Vt instability, and reliability, in devices fabricated with a conventional CMOS process technology according to A. Perera et al. (2000).

Design and fabrication of ultralight high-voltage power circuits for flapping-wing robotic insects (2011)

Flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biological insects and useful for a wide range of tasks, including exploration, environmental monitoring, search and rescue, and surveillance. Recently, robotic insects driven by piezoelectric actuators have achieved the important goal of taking off with external power; however, fully autonomous operation requires an ultralight power supply capable of generating high-voltage drive signals from low-voltage energy sources. This paper describes high-voltage switching circuit topologies and control methods suitable for driving piezoelectric actuators in flapping-wing robotic insects and discusses the physical implementation of these topologies, including the fabrication of custom magnetic components by laser micromachining and other weight minimization techniques. The performance of laser micromachined magnetics and custom-wound commercial magnetics is compared through the experimental realization of a tapped inductor boost converter capable of stepping up a 3.7V Li-poly cell input to 200V. The potential of laser micromachined magnetics is further shown by implementing a similar converter weighing 20mg (not including control functionality) and capable of up to 70mW output at 200V and up to 100mW at 100V.
