AAA Mechanism for the Integration between Heterogeneous Network in Wireless Network Roaming Environment (2008)

인터넷과 네트워크의 발전에 따라 유선 네트워크와 무선 네트워크가 결합되어 유/무선 통합시대가 전개되고 있다. 유/무선 통합 서비스 중에서 이기종 네트워크 환경에서의 보안 기술에 대한 연구는 아직 미흡한 실정이며, 이기종 네트워크의 융합은 서로 다른 네트워크의 융합으로 인해 기존의 보안 기술 및 통신 기술을 그대로 적용하기가 매우 어려워 보안 측면에서도 많은 취약점을 내포하고 있다. 또한 사용자들이 제공 받는 서비스의 형태는 대부분 이동 사용자를 위한 서비스가 될 것이며, 이러한 서비스에서는 로밍 시 빠른 인증 및 안전성을 제공하여야 한다. 따라서 본 연구는 이기종 네트워크 환경에서 로밍 및 AAA 메커니즘에 관한 연구를 진행하여 안전성과 효율성을 제공할 수 있도록 하였다. With the advancement of the Internet and networks, the combination of wired/wireless technologies is spreading rapidly since it enables the creation of new services and provides new features to both users and service providers. In such wired/wireless integrated services, network integration is very important because such systems are integrated by a linkage between heterogeneous networks and they involve an integration of transmission technologies across networks. In this situation, existing security and communication technologies are unsuitable since the network are integrated with heterogeneous networks. The network may also have several security vulnerability. Also, form of service that users offer will be service for roaming user. In these service, we must provide fast authentication and security at roaming. Therefore in this paper we proposed roaming and AAA mechanism in heterogeneous network environment. Our system provides secure communication and efficiency.

MMP2-Targeting and Redox-Responsive PEGylated Chlorin e6 Nanoparticles for Cancer Near-Infrared Imaging and Photodynamic Therapy (2015)

A unique matrix metalloproteinase 2-targeted photosensitizer delivery platform was developed in this study for tumor-targeting imaging and photodynamic therapy. The model photosensitizer therapeutic agent chlorin e6 (Ce6) was first covalently conjugated with matrix metalloproteinase 2-cleavable polypeptide and then modified with polyethylene glycol via a redox-responsive cleavable disulfide linker. The resultant matrix metalloproteinase 2-cleavable polypeptide modified PEGylated Ce6 (PEG-SS-Ce6-MMP2) nanoparticles, which formed via self-assembly, were observed to be monodisperse and significantly stable in aqueous solution. In addition, owing to their cellular redox-responsiveness at the cleavable disulfide linker, the PEG-SS-Ce6-MMP2 nanoparticles were able to release Ce6 rapidly. Despite displaying enhanced intracellular internalization, the synthesized PEG-SS-Ce6-MMP2 nanoparticles did not compromise their phototoxic effects toward A549 cancer cells when compared with free Ce6 and PEGylated Ce6 nanoparticles. In vivo experiments further revealed that, in contrast with the free Ce6 or with the PEGylated Ce6 nanoparticles, the PEG-SS-Ce6-MMP2 nanoparticles showed a remarkable increase in tumor-targeting ability and a significantly improved photodynamic therapeutic efficiency in A549 tumor-bearing mice. These results suggest that the PEG-SS-Ce6-MMP2 nanoparticles hold great potential for tumor-targeting imaging and photodynamic therapy.
Feeding Blueberry Diets to Young Rats Dose-Dependently Inhibits Bone Resorption through Suppression of RANKL in Stromal Cells (2013)

Previous studies have demonstrated that weanling rats fed AIN-93G semi-purified diets supplemented with 10% whole blueberry (BB) powder for two weeks beginning on postnatal day 21 (PND21) significantly increased bone formation at PND35. However, the minimal level of dietary BB needed to produce these effects is, as yet, unknown. The current study examined the effects of three different levels of BB diet supplementation (1, 3, and 5%) for 35 days beginning on PND25 on bone quality, and osteoclastic bone resorption in female rats. Peripheral quantitative CT scan (pQCT) of tibia, demonstrated that bone mineral density (BMD) and content (BMC) were dose-dependently increased in BB-fed rats compared to controls (P<0.05). Significantly increased bone mass after feeding 5% BB extracts was also observed in a TEN (total enteral nutrition) rat model in which daily caloric and food intake was precisely controlled. Expression of RANKL (receptor activator of nuclear factor-κB ligand) a protein essential for osteoclast formation was dose-dependently decreased in the femur of BB animals. In addition, expression of PPARγ (peroxisome proliferator-activated receptor γ) which regulates bone marrow adipogenesis was suppressed in BB diet rats compared to non-BB diet controls. Finally, a set of in vitro cell cultures revealed that the inhibitory effect of BB diet rat serum on RANKL expression was more profound in mesenchymal stromal cells compared to its effect on mature osteoblasts, pre-adipocytes and osteocytes. These results suggest that inhibition of bone resorption may contribute to increased bone mass during early development after BB consumption.
Laparoscopic orchiopexy (2015)

Diagnostic laparoscopy is the gold standard for identification of nonpalpable undescended testes and subsequent surgical planning. Primary or staged laparoscopic orchiopexy has improved surgical outcomes, as defined by acceptable scrotal position and lack of atrophy. Minimally invasive approaches to the intra-abdominal testis have also made outpatient treatment standard. At present, robotic and single-site surgical techniques have not demonstrated any identifiable advantage, though they are technically feasible. Complications of laparoscopic orchiopexy are uncommon, influenced in large part by surgeon experience and ongoing case volume. Measures to recognize and prevent the following complications must be well understood: testicular atrophy, malposition, avulsion or torsion, vasal injury, intra-abdominal organ or vascular injury, ileus and, rarely, inguinal or port site hernias. In addition, families require preoperative counseling on such complications as well as the possibility of orchiectomy and the need for staged or reoperative procedures.
Co-localization of the tumor-suppressor protein p53 and human papillomavirus E6 protein in human cervical carcinoma cell lines. (1993)

The loss of the tumor-suppressor activity of p53, either by mutation or by interaction with the human papillomavirus (HPV) E6 protein, is considered to be an important mechanism in the carcinogenesis of cervical cancer. We have studied the cytological distribution of these proteins in human cervical carcinoma cell lines using polyclonal anti-p53 and monoclonal anti-E6 antibodies. The antibody specificity was confirmed by immunoblot and immunocompetition analyses. The intracellular localization of p53 and E6 was detected using the techniques of conventional and three-dimensional confocal microscopy. In the HPV-18 or -16 integrated cell lines, HeLa, CaSki and SiHa, viral oncoprotein E6 and endogenous tumor-suppressor protein, p53, were observed by immunofluorescence in the cytoplasm; p53 also had a weak punctate staining in the nuclei of HeLa and CaSki cells. In the HPV-negative cervical carcinoma cell lines, C-33A and HT-3, which have mutated p53, p53 was localized predominantly to the nucleus, with C-33A cells having elevated levels of p53 compared with the other cell lines. High spatial resolution imaging, using confocal microscopy, was performed on the cells after double fluorescence staining for p53 (fluorescein) and E6 (rhodamine). The images showed that both p53 and E6 had similar cytoplasmic distributions, which implied that these two proteins may exist as a cytoplasmic complex. To substantiate this implication, fluorescence resonance energy transfer microscopy was performed, which provided direct evidence of a close association between p53 and E6 within individual HeLa cells. The results from this study support the theory that p53 protein binds HPV-16/18 E6 protein in the cell cytoplasm, thus preventing p53 from exerting its tumor-suppressor function in the nucleus. Hence, inactivation of wild-type p53 by p53-E6 complex formation in cervical cancer may be a critical step in malignant transformation.
Evaluating the Extension of Wall Displays with AR for Collaborative Work (2023)

Wall displays are well suited for collaborative work and are often placed in rooms with ample space in front of them that remains largely unused. Augmented Reality (AR) headsets can seamlessly extend the collaboration space around the Wall. Nevertheless, it is unclear if extending Walls with AR is effective and how it may affect collaboration. We first present a prototype combining a Wall and AR headsets to extend the Wall workspace. We then use this prototype to study how users utilize the virtual space created in AR. In an experiment with 24 participants, we compare how pairs solve collaborative tasks with the Wall alone and with Wall+AR. Our qualitative and quantitative results highlight that with Wall+AR, participants use the physical space in front and around the Wall extensively, and while this creates interaction overhead, it does not impact performance and improves the user experience.
Fundamental study for improvement of dewatering of fine coal/refuse. Annual report, July 1981-July 1982. Volume I (1982)

The overall objective of the study is to seek improved methods of dewatering through a better understanding of the filtration and post-filtration processes. As a first step, efforts have been focused on the mechanism of dewatering in terms of basic properties of coal (and refuse) particles and filter cakes and their relations to filtration rate and final cake moisture content. This annual report presents the highlights and accomplishments of the third year of the project. The report is divided into four parts: summary and deliverables; work forecast for the fourth year; detailed description of technical progress; and appendices. Volume I contains the first 3 parts. Progress reports are presented for the following tasks: (1) particle/filter cake characterization; (2) theoretical modelling; (3) experimental measurements of filtration and dewatering; and (4) enhanced dewatering method. 17 references.
Scophony Spatial Light Modulator (1985)

An alternative to the conventional flying-spot scanner architecture is the Scophony scanner. The Scophony scanner uses the same optical elements as the more familiar flying-spot scanner: a rotating polygon mirror, an acousto-optic (A/O) modulator, and a laser light source. The flying-spot scanner is designed to construct its image a pixel at a time; no more than one pixel is illuminated at any given instant. The Scophony scanner is designed to image a broad swath of the A/0 modulator's acoustic pulses onto the photoreceptor. Many pixels are illuminated at any given instant in the Scophony scanner. The result is a scanner with a coherent imaging response. This coherent response implies that the phase of the modulator's electronic drive signal for a given pixel profoundly influences the formation of the neighboring pixels at the scanner image plane. This coherent response enables electronic manipulation of the video drive signal to have significant impact on the optical imaging performance of the scanner. In this paper, two electronic manipulation schemes are pro-posed for doubling the resolution of the Scophony scanner, one scheme for analog video signals and one scheme for binary digital video signals. Each scheme gives superior contrast ratio performance when compared with the flying-spot scanner.
Superconductivity in 4 Angstrom Single-Walled Carbon Nanotubes (2001)

Investigation of the magnetic and transport properties of single-walled small-diameter carbon nanotubes embedded in a zeolite matrix revealed that at temperatures below 20 kelvin, 4 angstrom tubes exhibit superconducting behavior manifest as an anisotropic Meissner effect, with a superconducting gap and fluctuation supercurrent. The measured superconducting characteristics display smooth temperature variations owing to one-dimensional fluctuations, with a mean-field superconducting transition temperature of 15 kelvin. Statistical mechanic calculations based on the Ginzburg-Landau free-energy functional yield predictions that are in excellent agreement with the experiments.
Deterministic figure correction of piezoelectrically adjustable slumped glass optics (2017)

Thin X-ray optics with high angular resolution (&le; 0.5 arcseconds) over a wide field of view enable the study of a number of astrophysically important topics, and feature prominently in Lynx, a next-generation X-ray observatory concept currently under NASA study. To produce such optics, we propose to use piezoelectrically adjustable, thin mirror segments capable of figure correction after mounting and on-orbit. In the present work, we report on the fabrication and characterization of an adjustable cylindrical slumped glass optic. This optic has realized 100% piezoelectric cell yield and employs lithographically patterned traces and anisotropic conductive film (ACF) connections to address the piezoelectric cells. The response of the piezoelectric cells are found to agree with finite-element analysis models, and simulated corrections to distortions are found to improve 7 – 10 arcsecond mirrors to 1 – 2 arcseconds (HPD, single reflection at 1 keV). Moreover, such a figure change is empirically demonstrated using an adjustable slumped glass optic, and we identify a path for achieving subarcsecond corrections.
How long do patients with advanced cancer survive after discharge to sub-acute rehabilitation? (2018)

67 Background: Patients with advanced cancer inevitably experience a functional decline diminishing quality of life. Many are admitted to the hospital due to progression of disease and become further deconditioned. Discharge to sub-acute rehabilitation (SAR) to "gain strength" for future anti-cancer therapy is common as participation in more intensive rehab therapy is rarely possible. In this study, we wished to determine the length of survival after discharge to SAR and if factors such as pre-hospitalization ECOG correlated with increased length of survival. Methods: At our 926-bed urban academic center, we performed a retrospective chart review from June 2015 to January 2017 of hospitalized patients with solid cancers who were subsequently discharged to SAR. Patients were excluded if they had surgery, a cerebrovascular event during their hospitalization or no post-hospital oncology follow-up plan. The primary outcome was death. Results: Fifty-six patients were identified (median age 69, range 28-95; 87% African American; 72% female). Forty-seven (86%) had metastatic disease. Forty-seven patients (86%) were deceased as of June 2017. The mean survival from date of discharge was 114 days (SD 122.89, range 1-447). Twenty-eight patients (51%) had a pre-hospitalization ECOG of 1 or 2 and twenty-seven patients (49%) had an ECOG of 3 or 4. Mann-Whitney U correlation was used to test the correlation between ECOG and survival. Patients with an ECOG of 1 or 2 trended to survive longer (156 vs 75 days, p=0.06). Self identified white patients had a statistically significant longer survival post discharge to SAR compared to African Americans (204 vs 104 days, p=0.03). Conclusions: Compared to patients with ECOG 1 or 2, patients with ECOG of 3 or 4 survived for a fewer number of days. The identification of additional markers of poor prognosis through larger prospective multi-institutional studies will help to delineate which patients are more likely to benefit from discharge to SAR.
Isospecific homo‐ and copolymerization of styrene with ethylene in the presence of VCl3, AlCl3 as catalyst (1996)

Abstract The homopolymerization of styrene and its copolymerization with ethylene in the presence of a vanadium‐based supported catalyst, {VCI 3 , 1 AICI 3 }, associated to triethylaluminium is examined. As indicated by means of 13 C nuclear magnetic resoance and differential scanning calorimetry analysis, the homopolystyrenes obtained present a highly isotactic microstructure and are semicrystalline (melting temperature 220°C). In the case of styrene/ethylene random copolymerization, the formation of both, polyethylene blocks and isotactic polystyrene sequences was identified by analysis of the crude polymer. Solubility characteristics and structural characteristics from nuclear magnetic resonance spectra of these products support the formation of copolymers with ethylene and isotactic styrene blocks rather than that of two distinct homopolymers.

Can a rescuer or simulated patient accurately assess motion during cervical spine stabilisation practice sessions? (2011)

Background Proper stabilisation of suspected unstable spine injuries is necessary to prevent (worsen) spinal cord damage. Almost all training relies on subjective reports from the simulated patient or observations from an independent person. The reliability and validity of these measures remains unknown. Objective To determine 1) how accurately rescuers and simulated patients assess motion during cervical spine (c-spine) stabilisation practice, and 2) if providing feedback on performance influences behaviour preferences. Design Cross-over design. Setting and Participants 12 experienced therapists. Assessment Head Squeeze and Trap Squeeze (random order) c-spine stabilisation during four test scenarios: lift-and-slide (L&amp;S) and log-roll (LR) placement on spinal board, and agitated patient trying to sit up (AGIT-SIT) or rotate head (AGIT-ROT). Main outcome measurements Inter-rater reliability between rescuer and simulated patient quality scores for subjective evaluation of c-spine stabilisation during trials (0=best, 10=worst), correlation between rescuers' quality score and objective measure of motion with inertial measurement units (IMU), and frequency of change in preference for Head Squeeze vs Trap Squeeze. Results Although the weighted-kappa for inter-rater reliability was acceptable (0.71–0.74), scores varied by more than one points between rescuers/simulated patients for ∼10–15% of trials. Rescuers' scores correlated with objective measures but with large variability. For example, 38% of trials scored as almost perfect (0–1) by the rescuer actually had &gt;10° of motion in at least one direction. In general, feedback did not affect preference for L&amp;S. For the LR, 6/8 subjects preferring Head Squeeze at baseline preferred Trap Squeeze after feedback. For the confused patient, 5/5 subjects preferring Head Squeeze at baseline preferred Trap Squeeze after feedback. Conclusion Rescuers and simulated patients could not adequately assess performance during c-spine stabilisation without objective measures. Providing immediate feedback is a promising tool for teaching proper technique and for changing preferences of behaviour in this context.

A translational pharmacology approach to understanding the predictive value of abuse potential assessments (2013)

Within the drug development industry the assessment of abuse potential for novel molecules involves the generation and review of data from multiple sources, ranging from in-vitro binding and functional assays through to in-vivo nonclinical models in mammals, as well as collection of information from studies in humans. This breadth of data aligns with current expectations from regulatory agencies in both the USA and Europe. To date, there have been a limited number of reviews on the predictive value of individual models within this sequence, but there has been no systematic review on how each of these models contributes to our overall understanding of abuse potential risk. To address this, we analyzed data from 100 small molecules to compare the predictive validity for drug scheduling status of a number of models that typically contribute to the abuse potential assessment package. These models range from the assessment of in-vitro binding and functional profiles at receptors or transporters typically associated with abuse through in-vivo models including locomotor activity, drug discrimination, and self-administration in rodents. Data from subjective report assessments in humans following acute dosing of compounds were also included. The predictive value of each model was then evaluated relative to the scheduling status of each drug in the USA. In recognition of the fact that drug scheduling can be influenced by factors other than the pharmacology of the drug, we also evaluated the predictive value of each assay for the outcome of the human subjective effects assessment. This approach provides an objective and statistical assessment of the predictive value of many of the models typically applied within the pharmaceutical industry to evaluate abuse potential risk. In addition, the impact of combining information from multiple models was examined. This analysis adds to our understanding of the predictive value of each model, allows us to critically evaluate the benefits and limitations of each model, and provides a method for identifying opportunities for improving our assessment and prediction of abuse liability risk in the future.
Cytocompatibility and Cellular Internalization Mechanisms of SiC/SiO2Nanowires (2014)

First evidence of in vitro cytocompatibility of SiC/SiO2 core-shell nanowires is reported. Different internalization mechanisms by adenocarcinomic alveolar basal epithelial cells, monocytic cell line derived from an acute monocytic leukemia, breast cancer cells, and normal human dermal fibroblasts are shown. The internalization occurs mainly for macropinocytosis and sporadically by direct penetration in all cell models considered, whereas it occurred for phagocytosis only in monocytic leukemia cells. The cytocompatibility of the nanowires is proved by the analysis of cell proliferation, cell cycle progression, and oxidative stress on the cells treated with NWs as compared to controls. Reactive oxygen species generation was detected as an early event that then quickly run out with a rapid decrease only in adenocarcinomic alveolar basal epithelial and human dermal fibroblasts cells. In all the cell lines, the intracellular presence of NWs induce the same molecular events but to a different extent: peroxidation of membrane lipids and oxidation of proteins. The NWs do not elicit either midterm (72 h) or long-term (10 days) cytotoxic activity leading to irreversible cellular damages or death. Our results are important in view of a possible use of SiC/SiO2 core-shell structures acting as biomolecule-delivery vectors or intracellular electrodes.
