Rabi‐oscillations‐induced multiharmonic emission in a Maxwell–Schrödinger study of a dense sample of molecules (2001)

A solution of the combined Maxwell–Schrödinger equations for the propagation of an ultraviolet (UV) pulse in a sample of model H2+-like molecules (with only two electronic states), shows a significant increase of the emission at 5–10 harmonics for a thick-density (line integrated density of 50 a.u.−2) vs. a thin-density case. The increase is more than two orders of magnitude larger than the expected factor (the ratio of the squared densities) and is due to a “sharpening” effect whereby Rabi oscillations induce a spatially rapidly varying electric field that has very sharp peaks. Equally important, the molecular degree of freedom is shown to exert a strong influence on the emitted radiation so that multiharmonic emission can be controlled by preparing molecules in specific initial wavepackets. © 2001 John Wiley & Sons, Inc.

Detection of Activated STAT5 in Neoplastic Mast Cells in Patients with Systemic Mastocytosis: Role of c-kit D816V. (2005)

Abstract Recent data suggest that activated STAT5 contributes to growth and differentiation of mast cells (MC) and that STAT5-knock out mice are MC-deficient. We have recently shown that constitutively activated STAT5 acts as a potent oncogenic signaling molecule in hematopoietic progenitor cells (Cancer Cell2005;7:87–99). In the present study, we examined the expression of activated STAT5 in neoplastic MC in systemic mastocytosis (SM) and asked whether the SM-related oncogene c-kit D816V is involved in STAT5-activation. For the immunohistochemical detection of activated tyrosine phosphorylated STAT5 (P-Y-STAT5), we used the specific monoclonal antibody AX1 (Advantex) which does not react with inactive STAT5. In all patients with SM tested (indolent SM, n=11; smouldering SM, n=2; aggressive SM, n=1; mast cell leukemia, n=1; all exhibiting c-kit D816V), MC were found to display P-Y-STAT5. Expression of activated STAT5 was also demonstrable in the c-kit D816V-positive mast cell leukemia-derived cell line HMC-1. The reactivity of HMC-1 cells with AX1 antibody was abrogated by a STAT5-specific blocking-peptide. To define the role of c-kit D816V in STAT5-activation, Ba/F3 cells with doxycycline-inducible expression of c-kit D816V (Ton.kit) were employed. In these cells, induction of c-kit D816V was followed by a massive increase in phosphorylated STAT5 as determined by a specific DNA-binding assay, whereas the total amounts of STAT5-mRNA and of the STAT5-protein showed only a slight increase or remained unchanged. In summary, these data show that neoplastic MC in SM express activated STAT5 (P-Y-STAT5), and that the transforming c-kit mutation D816V leads to persistent activation of STAT5 in these cells.
Author response—nonoperative treatment of lateral epicondylitis: a systematic review and meta-analysis (2023)

We accept that lateral epicondylitis may be a degenerative condition and that inflammation may or may not be present. Although “lateral elbow tendinopathy” is acceptable, the term “lateral epicondylitis” remains in widespread use in the medical literature and in trials included in this study, and the term we chose to describe the condition for the purposes of our study.
Web searching agents, what are they doing out there? (2004)

The Web has become a worldwide repository of information, which individuals, companies, and organizations utilize to solve or address various information problems. Many of these Web users utilize automated agents to gather this information for them. It is assumed that this approach represents a more sophisticated method of searching. However, there is little research investigating how Web agents search for online information. In this research, we examine how agents search for information on Web search engines, including the session, query, term, duration and frequency of interactions. For this study, we analyzed queries that 2,717 agents submitted to the Alta Vista search engine on 8 September 2002. Findings include: (1) agents interacting with Web search engines use queries comparable to human searchers, (2) Web agents are searching for a relatively limited variety of information, with only 18% of the terms used being unique, and (3) agent-Web search engine interaction typically spans several hours with multiple instances of interaction per second.
Time-resolved emission spectroscopy as a tool to follow nucleic acid-protein interaction. (1995)

Fluorescence spectroscopy is undoubtedly a useful tool to study the structural and functional aspects of nucleic acids-protein interactions as well as the catalytic functions of particular residues of multi-subunit enzyme complexes. The dynamic interaction of nucleic acids and proteins occurring at nanosecond time scale can now be monitored by making life-time measurements or by time-resolved emission spectroscopy. These measurements are made by exploiting the intrinsic fluorescent residues in proteins i.e. W or by the use of extrinsic fluorophores which are tagged on to particular residues and that are sensitive to the microenvironment changes. In this study we describe the use of time resolved emission spectroscopy to (a) analyse the transient binding between sigma 70 and DNA by monitoring the quenching of W residues and (b) monitor the various states which nucleosomes of active, inducible or inactive chromatin may adopt in vivo.
Performing Respect: Using Enactments in Group Work with Men Who Have Abused (2006)

This article describes an approach to working with groups of men who have abused which uses dramatic enactments of conversational exchanges to approximate the conflictive interactions with partners that precipitated the referrals to the group. The approach is informed by the Domestic Abuse Intervention Program in Duluth, Minnesota, but differs in significant ways. Rather than placing a primary emphasis on the men as having an intent to wield power and control, the group facilitators assume multiple intentions. Drawing on the notion of restraints, intentions to interact in nonviolent ways are actively sought out, but are understood as restrained by various factors regarded as separate from the men in the narrative therapy tradition of externalizing. After establishing the theoretical context of the discussion, the article depicts the various uses of the dramatic enactments that help to provide a bridge between talking in abstract terms about violence and actively changing interactional patterns in situ with their partners.
Biodegradable polymers based on renewable resources. IX. Synthesis and degradation behavior of polycarbonates based on 1,4:3,6‐dianhydrohexitols and tartaric acid derivatives with pendant functional groups (2005)

Abstract Novel polycarbonates, with pendant functional groups, based on 1,4:3,6‐dianhydrohexitols and L ‐tartaric acid derivatives were synthesized. Solution polycondensations of 1,4:3,6‐dianhydro‐bis‐ O ‐( p ‐nitrophenoxycarbonyl)hexitols and 2,3‐di‐ O ‐methyl‐ L ‐threitol or 2,3‐ O ‐isopropylidene‐ L ‐threitol afforded polycarbonates having pendant methoxy or isopropylidene groups, respectively, with number average molecular weight ( M n ) values up to 3.6 1 × 10 4 . Subsequent acid‐catalyzed deprotection of isopropylidene groups gave well‐defined polycarbonates having pendant hydroxyl groups regularly distributed along the polymer chain. Differential scanning calorimetry (DSC) demonstrated that all the polycarbonates were amorphous with glass transition temperatures ranging from 57 to 98 °C. Degradability of the polycarbonates was assessed by hydrolysis test in phosphate buffer solution at 37 °C and by biochemical oxygen demand (BOD) measurements in an activated sludge at 25 °C. In both tests, the polycarbonates with pendant hydroxyl groups were degraded much faster than the polycarbonates with pendant methoxy and isopropylidene groups. It is noteworthy that degradation of the polycarbonates with pendant hydroxyl groups was remarkably fast. They were completely degraded within only 150 min in a phosphate buffer solution and their BOD‐biodegradability reached nearly 70% in an activated sludge after 28 days. The degradation behavior of the polycarbonates is discussed in terms of their chemical and physical properties. © 2005 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 43: 3909–3919, 2005
Liver embolizations of patients with malignant neuroendocrine gastrointestinal tumors (1998)

Liver embolizations performed relatively late in the clinical course in our series appeared to be as effective as "early" embolizations in other series of patients with carcinoid tumors. The results for those with EPTs were poorer, and earlier embolizations may result in better outcomes for these patients. Considering the morbidity associated with the procedure, it is imperative to select patients according to extent of liver involvement, severity of carcinoid heart disease, and somatostatin receptor status.
A Novel Approach to Bass Enhancement in Automobile Cabin (2006)

An audio enhancement system is presented to improve the sound quality, especially the bass reproduction in the automobile cabin. High quality audio reproduction in cabin can be difficult due to a number of factors, including the noise in the cabin, performance, size of the loudspeakers in the car. The proposed system uses digital signal processing techniques with the built-in car audio system to tune and make use of the engine noise. The main problems are the tracking of the engine noise and tune the noise to match the audio signal. In this paper, we propose a solution based on frequency sampling filters to track and extract the audio signal, and a multi-frequency active noise equalizer to tune the engine noise. The results showed that the proposed system could be a promising approach for solving the bass audio reproduction, together with the noise control problems in automobile

The Japan Society of Obstetrics and Gynecology collects and analyzes annual data on gynecologic cancers from member institutions. Here we present the Patient Annual Report for 2012 and the Treatment Annual Report for 2006. Data on 7028 patients with cervical cancer, 8217 with endometrial cancer, 5140 with ovarian cancer and 1725 with ovarian borderline tumor for whom treatment was initiated in 2012 were summarized in the Patient Annual Report. Data on the prognosis of 2699 patients with cervical cancer, 3243 with endometrial cancer and 1898 with ovarian cancer for whom treatment was initiated in 2006 were analyzed in the Treatment Annual Report. In the Patient Annual Report for 2012, stage I accounted for 55.4%, stage II for 23.0%, stage III for 11.0% and stage IV for 10.6% of all patients with cervical cancer. Stage I accounted for 72.2%, stage II for 7.0%, stage III for 13.4% and stage IV for 7.3% of all patients with endometrial cancer. Stage I accounted for 43.1%, stage II for 9.2%, stage III for 29.7% and stage IV for 7.2% of all patients with ovarian cancer. In the Treatment Annual Report for 2006, the 5-year overall survival rates for patients with cervical cancer were 92.9% for stage I, 74.6% for stage II, 55.3% for stage III and 24.3% for stage IV. The equivalent rates for patients with endometrial cancer were 96.3%, 92.7%, 80.6% and 35.8%, respectively; and those for patients with ovarian surface epithelial-stromal tumors were 90.6%, 82.9%, 48.7% and 40.9%, respectively.
Quantum logic gates with neutral atoms in an optical lattice (2002)

Summary form only given.Quantum logic gates require qubits that can interact strongly with each other and with external fields while minimizing unwanted coupling to the decohering environment. Neutral atoms trapped in a far-off resonance optical lattice satisfy these criteria. The adjustable parameters of the lattice (e.g., laser polarization, frequency, intensity) allow one to design interactions for which atoms interact strongly via dipole-dipole interactions during logical interactions but otherwise are isolated from each other and the environment. Dissipation arising from spontaneous photon scattering can be suppressed to an arbitrary degree given sufficient laser power and large detuning from atomic resonance. Thus, by bringing two atoms in close proximity, one can simultaneously achieve strong coherent coupling with small photon scattering rates.
Anticancer activity of a novel quinazolinone-chalcone derivative through cell cycle arrest in pancreatic cancer cell line (2015)

Background: Genotoxic effects of many of clinically useful anticancer drugs are due to their interaction with the amino groups of nucleic acids. Literature reveals that the chalcones however may be devoid of this important side effect. With this view in mind, we synthesized a novel quinazolinone-chalcone derivative and evaluated its anticancer potential. Methods: Anticancer potential of A novel quinazolinone-chalcone derivative 2-Methyl-3-(3-((E)-3-(3,4,5-trimethoxy phenyl)-2-propenoyl)phenyl)-3,4-dihydro-4-quinazolinone (8b) was determined through MTT assay, colony formation assay, Wound healing assay, Cell cycle and Western Blot Analysis in Mia paca-2 cells treated with 8b. Results: The cytotoxicity studies showed a concentration dependent decrease in cell viability of HCT-116, HL-60, PC-3, A-549, Mia pacca-2 and MCF-7 cell lines with IC 50 values ranging from 5.5 to 8.5 µM. The motility of Mia paca-2 cells treated with 8b was found inhibited in a dose dependent manner. Cell cycle studies revealed a concentration dependent rise in G2/M phase of cell cycle from 1% to 52%. Decreased expression of cyclins regulating G2/M transition of the cell cycle (cyclin B1 and cdk1) was recorded after treatment of Mia Paca-2 cells with 8b. Mitochondrial membrane potential was also significantly lost in cultures exposed to 8b. However, nuclear morphology of 8b treated Mia paca-2 cells revealed no significant changes. 8b significantly inhibited the growth of Ehrlich ascites carcinoma, Sarcoma-180 (ascites), Ehrlich tumor (solid) and Sarcoma-180 (solid). Conclusion: The findings are indicative of 8b exerting anticancer activity through cell cycle arrest at G2/M phase and not through apoptosis. Reduction in the motility of Mia paca-2 cells indicates anti-metastatic potential of 8b.
Supersampling multiframe blind deconvolution resolution enhancement of adaptive optics compensated imagery of low earth orbit satellites (2002)

We describe a postprocessing methodology for reconstructing undersampled image sequences with randomly varying blur that can provide image enhancement beyond the sampling resolution of the sensor. This method is demonstrated on simulated imagery and on adaptive-optics-(AO)-compensated imagery taken by the Starfire Optical Range 3.5-m telescope that has been artificially undersampled. Also shown are the results of multiframe blind deconvolution of some of the highest quality optical imagery of low earth orbit satellites collected with a ground-based telescope to date. The algorithm used is a generalization of multiframe blind deconvolution techniques that include a representation of spatial sampling by the focal plane array elements based on a forward stochastic model. This generalization enables the random shifts and shape of the AO-compensated point spread function (PSF) to be used to partially eliminate the aliasing effects associated with sub-Nyquist sampling of the image by the focal plane array. The method could be used to reduce resolution loss that occurs when imaging in wide-field-of-view (FOV) modes.
Hybrid topologies for series and shunt compensation of the line-commutated converter (2016)

This paper presents two concepts for enabling the operation of a line-commutated converter (LCC) at leading power angles. The concepts are based on voltage or current injection at the ac side of an LCC, which can be achieved in different ways. However, this paper focuses on the voltage and current injection by series-connected full-bridge cells that can generate voltages that approximate ideal sinusoids. Thus, hybrid configurations of an LCC connected at the ac side in series or in parallel with full-bridge cells are presented. Finally, these hybrid configurations are compared in terms of voltage and current rating.
Combined framing and error correction coding for the DS3 signal format (1995)

The paper proposes and analyzes a combined framing and error control scheme for the DS3 format in which the primary framing bits are replaced with parity check bits of a rate 0.9912 extended and shortened Hamming code. A fast syndrome computation scheme is developed for the code to facilitate faster reframe times. The proposed scheme has better overall reframing performance than conventional framing, and reduces the output BER to approximately 1360P/sub e//sup 2/. This is effective against error-rate floors or "dribble error" phenomena in fiber optical transmission. Primary applications are in advanced in-service performance monitoring and for throughput enhancement in ATM networking applications using leased DS3 carrier signals.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
SUSTAINABLE TECHNOLOGIES AND VALUABLE NEW POLYSACCHARIDE-BASED PRODUCTS FROM SUGAR BEET PULP (2004)

More effective utilization of sugar beet pulp generated from beet sugar processing can improve the economic viability of U.S. beet sugar production. Dried pulp pellet and shreds provide a nutritious and valuable animal feed co-product from pulp for both local and export markets. However, the future of such markets may be threatened by increased availability of alternative feed materials from grain-based bioethanol production and customer concern for beet pulp derived from genetically modified plants that are being developed and pending commercial release. Beet pulp represents a largely untapped source of cell wall polysaccharides such as pectin that can be recovered and converted into higher-value biobased products. New biobased products are therefore sought from beet pulp to generate more revenue for growers and processors and to replace imported and/or petroleum-based products. Research on our CRIS (Official ARS/USDA Research) project is being conducted toward developing fundamental knowledge of the enzyme and polysaccharide components of the sugar beet cell wall; creating innovative new functional food, feed, and non-food biomedical and industrial bioproducts; and establishing efficient and sustainable conversion processes for their isolation and production. Our specific objectives, capabilities, and accomplishments are summarized in this report.

Downlink Transmission Optimization Framework (2012)

This paper presents an optimization framework for downlink transmission parameters of mobile cellular systems. A typical network optimization approach is to divide the network into disjoint clusters of base-stations (BS). Optimization is then performed within each cluster for important parameters such as transmit power, precoder, etc. This approach is widely adopted in academic research and industrial standard bodies, e.g. 3GPP LTE-Advanced. While reducing the optimization complexity, this strategy suffers from a performance limit due to interference from the nodes outside cluster. We thus propose a framework to overcome this limit by allowing clusters to exchange their parameters and optimization information via low-rate and non-zero delay backhauls. System-level simulations for LTE downlink transmit power optimization show that the proposed optimization model, while having the low-complexity of cluster-based approach, could nearly achieve the performance of network-wise optimization. Therefore, this model is particularly suitable for optimization of 4G and beyond-4G cellular networks.
Thermogelling behaviour of PEG-enclatherated Methylcellulose/Alginate sols (2021)

Thermogelling systems offer several advantages over conventional cross-linked hydrogels with respect to showing stimuli responsiveness and reversibility. They also offer functional and fabrication flexibility in terms of the design, injectability, and performance control offered by the in situ phase transition at various temperatures. Once gelled at the site of application or after injection, thermogels provide passive targeting with increased efficacy and decreased toxicity of the incorporated drugs. In this research, we describe methylcellulose-based thermogels blended with sodium alginate and enclatherated with poly(ethylene glycol) 400 (PEG400). The concentration of methylcellulose (MC) was kept constant at 4.0% ^w / _v while that of sodium alginate (ALG) varied from 0.5 to 2.0% ^w / _v . Clear sols were obtained and PEG400 were added (1 ml or 2 ml/10 ml of sol) to obtain final thermogels. The tripolymeric blend displayed hydrogen bonded O–H…C=O which was not evident in the bipolymeric systems (FTIR analysis). The DSC analysis corroborated the above with the absence of MC exotherm in tripolymeric blend formulations and the hijacking of MC-ALG interaction by the enclatherated PEG chains. The temperature ramp rheological profiling of the thermogels (20 °C–50 °C) revealed an increase in elastic modulus of M4A20P2 (sol with highest weight content) due to PEG400 interactions with ALG which in turn interacted with MC forming a self-assembled repeating network structure: PEG400-ALG-{ _hydrophillic MC _hydrophobic }-{ _hydrophobic MC _hydrophilic }-ALG-PEG400. With MC forming the hydrophobic or dehydrated part of the thermogel, ALG and PEG chains concentrated in the aqueous medium and were compressed from both side by the stiff MC architecture creating ‘intra- and inter-network stress’ induced polymer-polymer interactions. In conclusion, MC-ALG-PEG formed as complex thermoresponsive system showing physical restructuring induced chemical stabilization (PRICS) and can be employed in various biomedical applications.
