Responses of Adult Anopheles Stephensi to Light of Various Wavelengths1 (1972)

In simultaneous exposures to an incandescent lamp and to selected wavelengths of monochromatic light, Anopheles stephensi showed significant preferences for certain of the test colors. It demonstrated a strong positive reaction toward the middle ultraviolet wavelength 290 mμ, and in common with many other insect species, toward 365 mμ in the near ultraviolet region. Light at 690 mμ near the infrared also induced a strong positive behavioral response. Colors in the blue-green-yellow portion of the spectrum were less attractive than incandescent light. Light traps equipped with BLB-type fluorescent lamps, which peak in the region of 360 mμ, appear to have excellent potential for surveillance of A. stephensi populations.
Use of sulfonation procedure for the development of thermally stabilized isotactic polypropylene fibers prior to carbonization (2011)

Abstract Thermally stabilized isotactic polypropylene fibers were developed using sulfonation procedure prior to carbonization stage. Sulfonation was performed to make the fibers infusible, intractable, and insoluble with concentrated sulfuric acid (approx. 95–97% conc.) at a temperature of 120°C for sulfonation times ranging from 0.5 to 8 h. Sulfonation results in highly crosslinked structures which are thermally stabilized thus making the structure suitable to withstand the high temperatures involved in the carbonization stages. Structural characterization of sulfonated polypropylene fiber was carried out using combination of elemental analysis, differential scanning calorimetry, thermogravimetric analysis, and infra‐red spectroscopy techniques with the aim of following the structural developments at a molecular level. Precursor fibers sulfonated for sulfonation times of 6 h or longer retained up to 46% of their mass at 1000°C. DSC and IR‐spectroscopy observations indicate the gradual loss of isotacticity and crystallinity with the progress of sulfonation treatment. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Signal detection and extraction by cepstrum techniques (1972)

A technique for decomposing a composite signal of unknown multiple wavelets overlapping in time is described. The computation algorithm incorporates the power cepstrum and complex cepstrum techniques. It has been found that the power cepstrum is most efficient in recognizing wavelet arrival times and amplitudes while the complex cepstrum is invaluable in estimating the form of the basic wavelet and its echoes, even if the latter are distorted. Digital data-processing problems such as the detection of multiple echoes, various methods of linear filtering the complex cepstrum, the picket-fence phenomenon, minimum-maximum phase situations, and amplitude- versus phase-smoothing for the additive-noise case are examined empirically and where possible theoretically, and are discussed. A similar investigation is performed for some of the preceding problems when the echo or echoes are distorted versions of the wavelet, thereby giving some insight into the complex problem of separating a composite signal composed of several additive stochastic processes. The threshold results are still empirical and the results should be extended to multi-dimensional data. Applications are the decomposition or resolution of signals (e.g., echoes) in radar and sonar, seismology, speech, brain waves, and neuroelectric spike data. Examples of results are presented for decomposition in the absence and presence of noise for specified signals. Results are tendered for the decomposition of pulse-type data appropriate to many systems and for the decomposition of brain waves evoked by visual stimulation.
Effect of local retransmission at wireless access points on the round trip time estimation of TCP (2002)

The transmission control protocol (TCP) has been mainly designed assuming a relatively reliable wireline network. It is known to perform poorly in the presence of wireless links because of its basic assumption that any loss of a data segment is due to congestion and consequently it invokes congestion control measures. However, on wireless access links, a large number of segment losses will occur more often because of wireless link errors or host mobility. For this reason, many proposals have recently appeared to improve TCP performance in such environment. They usually rely on the wireless access points (base stations) to locally re-transmit the data in order to hide wireless losses from TCP. The authors use extensive simulations to evaluate TCP performance in the presence of congestion and wireless losses when the base station employs one of two proposals, namely Snoop and WTCP. The results show that WTCP significantly improves the throughput of TCP connections due to its unique feature of hiding the time spent by the base station to locally recover from wireless link errors so that TCP's round trip time estimation at the source is not affected. This proved to be critical since otherwise the ability of the source to effectively detect congestion in the fixed wireline network is hindered.

Bioflavonoids commonly and potently induce tyrosine dephosphorylation/inactivation of oncogenic proline-directed protein kinase FA in human prostate carcinoma cells. (1998)

In this study, we investigate the effect of bioflavonoids on the activity and phosphotyrosine content of oncogenic proline-directed protein kinase FA (PDPK FA) in human prostate carcinoma cells. Chronic treatment of human prostate carcinoma cells with low concentrations of quercetin, apigenin, and kaempferol commonly and potently induced tyrosine dephosphorylation and concurrent inactivated oncogenic PDPK FA in a concentration-dependent manner. This is demonstrated by a specific assay of this kinase's activity in the immunoprecipitates from the cell extracts followed by immunoblotting and phosphotyrosine analysis. The results indicate that bioflavonoids may function as common tyrosine kinase inhibitors to inhibit PDPK FA-specific tyrosine kinase and thereby to induce tyrosine dephosphorylation/inactivation of this oncogenic kinase in human carcinoma cells. Under this condition, quercetin, apigenin, and kaempferol can also inhibit cell growth in a similar concentration-dependent manner. The results further indicate that inhibition of tyrosine phosphorylation/activation of this oncogenic PDPK represents a new mode of action mechanism for bioflavonoids during the antiproliferation process in human carcinoma cells.
Determining the Sequence of Ball-Point Pen Writings—A New Method? (1978)

Abstract Examiners of questioned documents are frequently faced with the problem of determining the sequence of crossed lines. The answer to the question of line sequence can be of immense importance. To determine which of two intersecting pen strokes was made first may ultimately decide the outcome of a contested court case, or even negate the necessity of a trial. The disclosure of a cleverly perpetrated fraud or the sustaining of a genuine writing in controversy may result from such a determination.
Caries preventive effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP): a meta-analysis (2009)

Within the limitations of this systematic review with meta-analysis, the results of the clinical in situ trials indicate a short-term remineralization effect of CPP-ACP. Additionally, the promising in vivo RCT results suggest a caries-preventing effect for long-term clinical CPP-ACP use. Further randomized control trials are needed in order to confirm these initial results in vivo.
ERCC1 polymorphism, expression and clinical outcome of oxaliplatin-based adjuvant chemotherapy in gastric cancer (2008)

ERCC1 codon 118 polymorphism has no significant impact on ERCC1 mRNA expression, and the intratumoral ERCC1 mRNA level but not codon 118 polymorphism may be a useful predictive parameter for the relapse and survival of gastric cancer patients receiving oxaliplatin-based adjuvant chemotherapy.
Serum levels of tumour necrosis factor-alpha and interleukin-1 beta during leprosy reactional states. (1991)

The possible role of cytokines in leprosy reactions was investigated by analysing the levels of tumour necrosis factor (TNF) and interleukin-1 (IL-1) in serum samples from 39 leprosy patients, 22 of them presenting either type I (upgrading) or type II (ENL) reactions. Fifty per cent of the patients showed elevated concentrations of TNF and IL-1 in at least one of the serum samples tested. This included all four patients undergoing type I reversal reaction and nine (50%) of the ENL patients studied. Concentrations of TNF above 1000 pg/ml were found in four patients with ENL. Development of erythema multiforme in these ENL patients represented an aggravating factor and all four patients suffering from this type of lesion demonstrated increased serum TNF levels. All BT patients tested presented elevated IL-1 levels, while only half of them presented elevated levels of TNF. No correlation was found between any particular systemic symptoms and the levels of TNF and IL-1. These results suggest that TNF and IL-1 may be implicated in leprosy reactions, either acting directly or in synergism with other cytokines.
Patient outcomes after lumbar spinal fusions (1992)

<h3>Objectives.</h3> —To determine success and complication rates for lumbar spinal fusion surgery, predictors of good outcomes, and whether fusion improves success rates of laminectomy for specific low back disorders. <h3>Data Sources.</h3> —English-language journal articles published from 1966 through April 1991, identified through MEDLINE searching (<i>spinalfusion</i>plus limiting terms), bibliography review, and expert consultation. <h3>Study Selection.</h3> —Articles were selected only if they reported at least 1 year of follow-up data enabling the classification of clinical outcomes as satisfactory or unsatisfactory for at least 30 patients. <h3>Data Extraction.</h3> —Two reviewers independently extracted data on patient characteristics, surgical methods, patient outcomes, and quality of study methods. <h3>Data Synthesis.</h3> —Of 47 articles, there were no randomized trials. Four nonrandomized studies compared surgery with and without fusion for herniated disks; three found no advantage for fusion. On average, 68% of patients had a satisfactory outcome after fusion, but the range was wide (16% to 95%), and the satisfactory outcome rate was lower in prospective than in retrospective studies. The most frequently reported complications were pseudarthrosis (14%) and chronic pain at the bone graft donor site (9%). Clinical outcomes did not differ by diagnosis or fusion technique, but were worse in studies with a greater number of previously operated patients. <h3>Conclusions.</h3> —For several low back disorders no advantage has been demonstrated for fusion over surgery without fusion, and complications of fusions are common. Randomized controlled trials are needed to compare fusion, surgery without fusion, and nonsurgical treatments in rigorously defined patient groups. (<i>JAMA</i>. 1992;268:907-911)
On the bandwidth of carrier-type dc amplifiers (1970)

For a carrier-type amplifier (e.g., a chopper amplifier), it is well known that the low-frequency response may extend to dc. The position regarding the high-frequency response is not as clear, and statements in the literature give various fractions of the fundamental carrier frequency as an upper limit to the input-signal bandwidth that can be recovered from the modulated carrier. It is argued here that there is no simple well-defined theoretical upper limit, and that in practical circuits the fundamental carrier frequency may or may not be one of several factors determining the useful bandwidth. The circuit of a novel wide-band dc amplifier, consisting of two synchronized chopper amplifiers operating in parallel, is described. The frequency response of this amplifier is independent of the chopping rate, and its method of operation may help clarify bandwidth limitations.

Uncovering the cellular capacity for intensive and specific feedback self-control of the argonautes and MicroRNA targeting activity (2020)

The miRNA pathway has three segments-biogenesis, targeting and downstream regulatory effectors. We aimed to better understand their cellular control by exploring the miRNA-mRNA-targeting relationships. We first used human evolutionarily conserved sites. Strikingly, AGOs 1-3 are all among the top 14 mRNAs with the highest miRNA site counts, along with ANKRD52, the phosphatase regulatory subunit of the recently identified AGO phosphorylation cycle; and the AGO phosphorylation cycle mRNAs share much more than expected miRNA sites. The mRNAs for TNRC6, which acts with AGOs to channel miRNA-mediated regulatory actions onto specific mRNAs, are also heavily miRNA-targeted. In contrast, upstream miRNA biogenesis mRNAs are not, and neither are downstream regulatory effectors. In short, binding site enrichment in miRNA targeting machinery mRNAs, but neither upstream biogenesis nor downstream effector mRNAs, was observed, endowing a cellular capacity for intensive and specific feedback control of the targeting activity. The pattern was confirmed with experimentally determined miRNA-mRNA target relationships. Moreover, genetic experiments demonstrated cellular utilization of this capacity. Thus, we uncovered a capacity for intensive, and specific, feedback-regulation of miRNA targeting activity directly by miRNAs themselves, i.e. segment-specific feedback auto-regulation of miRNA pathway, complementing miRNAs pairing with transcription factors to form hybrid feedback-loop.
FPGA based hardware-software co-designed dynamic binary translation system (2013)

Binary translation is used to allow applications of one instruction set architecture (ISA) to run on another, thereby maintaining the binary level compatibility across ISAs. Conventional software binary translation systems suffer performance loss because of architectural heterogeneity amongst ISAs, control flow translation and context switches. In this paper, we propose an FPGA based hardware-software co-designed dynamic binary translation (DBT) system, which moderates these issues at a low level of hardware cost. In our DBT system, we propose a MIPS condition code flags register and a modest ISA extension to bridge the architectural gap, a hardware address mapping mechanism to accelerate the handling of control flow instructions, and a scratchpad memory to reduce performance loss during context switches. We implement the system on Xilinx XC5VLX110T. Quantitative experiments reveal that the overall performance improvement is 56.1% over the baseline configuration, with only extra 1.4% of slices and 5.4% of BRAMs of Xilinx XC5VLX110T occupied.
Controlled dewetting as fabrication and patterning strategy for metal nanostructures (2015)

Metal thin films and metal nanostructures find a key role in the actual nanotechnology revolution. They can be engineered for nanoelectronics, plasmonics, and sensing applications. However, the crucial step toward reliable technological applications of metal-based nanodevices is the development of simple, low cost, versatile, and high-throughout nanofabrication methodologies. In general, top-down nanofabrication approaches allow a minimum size of the single nanostructure higher than 10 nm, a high control on spatial regularity and size of the nanostructures, but involve high cost and long processing time. In contrast, bottom-up approaches allow a minimum size of the single nanostructure lower than 10 nm, a low control on spatial regularity and size of the nanostructures, but involve low cost and short processing time. In this paper, the controlled dewetting process of thin metal films on surfaces is reviewed as a patterning and nanofabrication method for metal-based nanocomposites, crossing the strenghts of both approaches.
Tuning the Ground State and Excited State Properties of Monocationic Iridium(III) Complexes by Varying the Site of Benzannulation on Diimine Ligand (2017)

Extending π-conjugation of the diimine ligand (N^N ligand) via benzannulation is a common way to tune the absorption and emission energies of cationic iridium(III) complexes. However, it can cause either a red- or blue-shift of the absorption and emission bands depending on the site of benzannulation. To understand the mechanism of changes in optical transitions upon benzannulation on the diimine ligand, a series of new cationic iridium(III) complexes [Ir(dppi)<sub>2</sub>(N^N)]PF<sub>6</sub> (1-6) (where dppi =1,2-diphenylpyreno[4,5-d]imidazole; N^N = 2-(pyridin-2-yl)quinoline (1), 2-(pyridin-2-yl)[7,8]benzoquinoline (2), 2,2'-bisquinoline (3), 2-(quinolin-2-yl)[7,8]benzoquinoline (4), 2-(pyridin-2-yl)[6,7]benzoquinoline (5), 2-(quinolin-2-yl)[6,7]benzoquinoline (6)) containing diimine ligand with varied degrees of π-conjugation via benzannulation at different sites of the 2-(pyridin-2-yl)quinoline ligand were synthesized. Experimental results and density functional theory (DFT) calculations revealed that benzannulation at the 6,7-position of quinoline and/or the 5',6'-position of pyridine (3, 5, and 6) induced red-shifts in their absorption and emission bands with respect to the parent complex 1; while benzannulation at the 7,8-position of quinoline resulted in blue-shifts (2 vs 1 and 4 vs 3). This phenomenon was rationalized by the symmetry of the frontier molecular orbitals at the site of benzannulation, which stabilized or destabilized the lowest unoccupied molecular orbital (LUMO) upon interactions with 1,3-butadiene, while the energy of the highest occupied molecular orbital (HOMO) remained nearly the same. This discovery would enable a rational design of organic or organometallic compounds that have predetermined absorption and emission energies.
Complete throughput analysis of the static four-phase-divided wind imaging interferometer (2012)

The static wind imaging interferometer, based on a four-phase-divided mirror, is an attractive approach to acquiring the wind velocity and temperature of the upper atmosphere. Herein the operational principle of the interferometer is presented in detail. The throughput is theoretically analyzed with consideration of the reflections and transmittances of each systemic component. The throughput expression is derived by employing the Fresnel theorem. We conducted simulations, and the results show that the energy transmittance reaches 20% on the surface with high reflectivity-coating film when the inclination angle of the input light is limited to the range of −5 to +5 deg. The results presented herein provide a theoretical basis for the static design configuration and coating for the upper atmosphere wind imaging interferometer.
A clinical study on the prolonged antihypertensive effect of clonidine in a sustained-release capsule formulation. (1980)

Eight patients with essential hypertension each received a single oral dose of 1 capsule of a sustained-release formulation of 0.25 mg clonidine in the morning for 3 consecutive days. Pulse ratio and blood pressure were measured in the standing and supine positions at specific intervals. After the first day of treatment, a significant decrease in blood pressure lasting 24 hours was recorded for the standing position. In the supine position, there was a progressive decrease in blood pressure which also attained significance on the third day of treatment. There was a progressive and significant reduction in mean arterial pressure from the first to the third day.
E-commerce Security Implementations— Think Before You Act (2002)

Smashed again It seems that in my business career, I have been gravely inconvenienced again and again by the thoughtless security decisions of other decision makers. As I write this article, I am in the process of being severely disrupted again, and I am getting a bit tired of simply taking it because I am too small and powerless to mean enough to the vendors who disrupt my business for them to care enough about providing me with the service I pay for.
How Will We Know the Millennium Development Goal Results When We See Them? (2005)

Results based monitoring and evaluation (M&E) is a powerful public management tool to help policy makers track progress and demonstrate the outcomes and impacts of a given policy, program, or project. In the context of MDG's having results based M&E system is important to assess whether governments are effectively using resources and making appropriate policy choices to achieve progress towards MDG achievement. Developing countries need as good as or better information than the more affluent countries to make decisions for they can least afford to put in place strategies that have weak implementation, have no discernible results, or are unfocused. Thus, the information and analysis that can come from a results-based M&E system goes to the heart of the matter for poorer countries-how will they know results when they seem them and how can they gather sufficient information to continually ensure they are using their scarce resources most appropriately in pursuit of their MDG's. The introduction of results based M&E strategies in developing countries is still in its infancy. As these governments move forward with their own strategies, they are trying new and innovative approaches that are enriching the pool of data and experiences. There is no blue print for moving forward and the challenges faced by developing countries are many. This paper discusses some approaches tried in a number of countries to build MDG results based M&E systems and some of the challenges encountered along the way.
