P‐7.11: A Study on Local Dimming Algorithm Design for MINI LED Backlight Display Quality Improvement (2022)

Today HDR (High Dynamic Range) Displays are increasingly developed. The HDR Display with mini‐led backlight and liquid‐crystal panel plays an important role, it has a lot of advantages like high light (more than 1000nits), high contrast ratio (more than 100000:1), bright color and good permeability and so on. But it also has some display defects like halo [3] phenomenon in a dark scene. In this paper, first, we discuss some common picture quality issues caused by the normal local dimming algorithm [2] and then present a novel algorithm base on BOE COG (chip on glass) mini‐led backlight HDR display. The BOE COG technology is a global unique glass substrate backlight solution, and has some features to help the algorithm improve its performance. And for the local dimming display issues, the algorithm itself has room for optimizing visual effects. Finally, around the key point of local dimming algorithm, we show several advantages of BOE glass substrate backlight solution, its distinctive features can help the algorithm improve picture quality.
The Determination of Stresses in Rolling-Contact Elements (1967)

Stress patterns in lubricated rolling-contact elements have been computed from surface pressures and temperatures between pairs of rolling disks, both cylindrical or both crowned, measured by means of evaporated surface transducers. The maximum mechanical shearing stresses computed for both cylindrical and crowned disks proved to be nearly equal to those that would have occurred under static contact, but the calculated depth of those stresses was reduced for cylindrical rollers in dynamic contact. The maximum shear reversals computed for rolling cylindrical disks were noticeably below the corresponding shear differences for the static cases. Local pressure anomalies, such as the pressure spike in the one particular case chosen for investigation, did not seem to alter significantly the shear-stress patterns. Thermal shearing stresses do not appear to be a significant portion of the maximum stress but do dominate over mechanical shearing stresses near the surface of the elements.
41. IMPLANT POSITIONING AS A FUNCTION OF APPROACH FOR HIP ARTHROPLASTY: LATERAL HEMIMYOTOMY VERSUS MINI-INVASIVE ANTEROLATERAL (RÖTTINGER). MULTICENTRIC PROSPECTIVE COMPARISON (2011)

Purpose of the study: The survival of a total hip arthroplasty (THA) depends mainly on the choice of the implant and the quality of the implantation. Mini-incisions have been criticised because of the increased risk of complications and the uncertainty concerning implant position. The main objective of this work was to assess this later feature. Material and method: This was a prospective series of consecutive patients attending different centres from January 2008 to January 2009 comparing 100 THA implanted via the reduced Watson-Jones approach (2 centres) and 520 THA implanted in a third centre via the anterior hemimyotomy. Objective assessment (PMA, Harris) and early functional outcome (WOMAC, SF12), biological aggression (myoglobinaemia, CPK, blood loss), complications, and scanographic position of the implants were analysed. Results: For the mini-Watson-Jones arthroplasties, there was a longer operative time (p Discussion: This series confirms the contribution of the mini-incision to more rapid recovery. We did not find any difference in implant malposition related to approach. The first analyses did however show that the position of the implants is more reproducible with the conventional approach.

Estimating the characteristics of vegetation canopies with airborne radar measurements (1993)

Abstract Possible use of synthetic aperture radars (SAR) for monitoring agricultural canopies is investigated in this paper. Data have been acquired on the Orgcval watershed during the AGRISCATT'88 campaign. Four radar experiments were carried out with the airborne scattcrometer ERASME (C and X bands, HH and VV polarizations, multi-incidence angles). Simultaneous ground measurements (soil moisture, leaf area index, water content of the canopy) were conducted on 11 wheat fields. Backscattering coefficients of the canopies arc interpreted in the framework of semi-empirical ‘water-cloud’ models. A simple paramctrization of the angular effect of soil roughness is introduced, allowing the simultaneous use of multi-incidence angle radar data. With a unique set of parameters for each radar configuration ‘ frequency and polarization’ the water-cloud model appears to describe adequately the backscattering of all the fields, over the range of incidence angles. It is shown that in this case, attenuation is the dominant effect of the vegetation and an inversion algorithm is proposed for estimating the water content of vegetation. This algorithm requires measurements at two different incidence angles and various combinations of radar configurations are then tested.
Novel Binding Motif of ACTH Analogues at the Melanocortin Receptors (2009)

The melanocortin receptor (MCR) subtype family is a member of the GPCR superfamily, and each of them has a different pharmacological profile with regard to the relative potency of the endogenous and synthetic melanocortin peptides. Alpha-MSH and ACTH are endogenous nonselective agonists for MC1R, MC3R, MC4R, and MC5R. In this study, we examined the role of Phe(7) in ACTH on human (h) MC1R, MC3R, and MC4R binding and signaling. Our results indicate that substitution of Phe(7) with d-Nal(2')(7) in ACTH1-24 yields a pharmacological profile different from that for substitution of Phe(7) with d-Nal(2')(7) in MSH in hMC1R, hMC3R, and hMC4R. N-d-Nal(2')(7)-ACTH1-24 is an agonist at hMC3R and hMC4R which did not change the peptide from an agonist to an antagonist at hMC3R and hMC4R. Further experiments indicate that N-d-Nal(2')(7)-ACTH1-17 is the minimal peptide required for hMC3R and hMC4R activation. Single-amino acid substitution studies of d-Nal(2')(7)-ACTH1-17 indicate that amino acid residues 15-17 in N-d-Nal(2')(7)-ACTH1-17 are crucial for hMC3R and hMC4R activation. Substitutions of these amino acid residues reduced or abolished agonist activity at hMC3R and hMC4R. Conformational studies revealed a new beta-turn (Arg(8)-Trp(9)-Gly(10)-Lys(11)) in N-d-Nal(2')(7)-ACTH1-17, compared to the beta-turn-like structure at NDP-alpha-MSH (His(6)-d-Phe(7)-Arg(8)-Trp(9)). Our results suggest that NDP-alpha-MSH and N-d-Nal(2')(7)-ACTH1-17 do not share the same binding site; the highly basic C-terminal fragment (Lys(15)-Lys(16)-Arg(17)) of N-d-Nal(2')(7)-ACTH1-17 induced a new beta-turn, and this shift contributed the selective agonist activity at hMC3R and hMC4R.
Traumatic atlantoaxial rotatory dislocation in adults. (2008)

Pure traumatic atlantoaxial rotatory dislocation (TAARD) is a possible cause of torticollis in children, but very rare in adults. Aim of this study is to report three very rare cases of TAARD in adults, focusing anatomy, management, and outcome. All 3 patients had a head-on automobile accident. Cases included a 26-year old woman, a 21-year old woman, and a 29-year-old man. The first case had a 45-day delay in diagnosis; the second and third cases were suspected to have odontoid lateral mass asymmetry on transoral radiographs. In all cases CT scan confirmed diagnosis and clarified the type of subluxation. All had conservative treatment with reduction and immobilization with Halo-Vest for case 1 and 2, and a rigid cervical collar for case 3. After follow-up of 10 years for case 1 and 2, and 3 years for case 3, all had no sign of C1-C2 complex mobility/instability. Patients 2 and 3 had complete and pain free cervical spine range of motion, while case 1 had stiffness and straightness of the cervical spine, headache, and nerve roots deficits, probably due to the complex cervical spine injury with sagittal imbalance on X-ray and C5-C6 spinal cord compression (pre-existing the trauma). TAARD should be considered in the differential diagnosis of post-traumatic neck pain and limitation, with or without evident torticollis, even in adults. CT scan is mandatory for a correct evaluation of C1-C2 complex. Conservative treatment with reduction followed by 50-60 days of rigid cervical immobilization (3 months in delayed diagnosis) is usually effective. Delay in diagnosis could be the cause of a poor outcome.
Mild liver abnormalities associated with elevated plasma factor VII and protein C in hypertriglyceridaemic patients. (1994)

We suggest that mild liver abnormalities such as steatosis may be one of the factors which can lead to an increase in factor VII and protein C levels.
Medium voltage cable defects revealed by off-line partial discharge testing at power frequency (2006)

This paper describes typical cable defects uncovered while testing over 9,000 km of medium voltage XLPE insulated cables. After a brief review of the testing method, the procedure that led to the identification, localization, and characterization of typical defects found in operating cables is described. The paper also discusses the "conversion" of water trees (WT) to electrical trees (ET) which are associated with partial discharge (PD) activity in the context of laboratory research. Based on actual service performance of cables, several cases in which ETs associated with WTs did not lead to cable failure even after several years of service in very harsh operating environments are cited.

Qualitaet der Verkehrsinfrastruktur amerikanischer Metropolen / A comparison of US metropolitan areas' traffic and infrastructure systems (2009)

Im Rahmen der vorliegenden Analyse wurden insgesamt 20 US-Metropolen und deren Verkehrskenngroessen ab dem Jahr 1982 ausgewertet. Ausserdem wurde versucht, die Verkehrsinfrastruktur zu klassifizieren und systematisch zu beschreiben. Anschliessend wurden allgemeine Trends erlaeutert und die Ergebnisse fuer die vier Metropolen New York, Chicago, Los Angeles und San Francisco detaillierter vorgestellt. Die Standardprozeduren zur Ermittlung der verkehrlichen Kenngroessen eines Ballungsraumes in den USA koennten nach methodischen Anpassungen auch auf deutsche Verhaeltnisse uebertragen und angewendet werden. Die urspruengliche Idee des Highway Performance Monitoring Systems bestand nicht in einer kontinuierlichen Beobachtung der Verkehrsverhaeltnisse, sondern vielmehr in einer Ausbaubedarfsfeststellung der Strasseninfrastruktur. Diese koennte durch derartige Analysen auch in Deutschland unterstuetzt werden. (A) ABSTRACT IN ENGLISH: The analysis covers 20 US metropolitan areas and their traffic results since 1982. The authors also systematically categorized the transport infrastructure of these metropolitan areas. General trends are highlighted, while the research results for New York City, Chicago, Los Angeles and San Francisco are explained in detail. The Urban Mobility Report and the Highway Performance Monitoring System have served as a data basis for all the metropolitan areas. Traffic results are arranged in chronological order, going back to the first records of 1982. The main purpose of the research has been the evaluation of congestion levels, including their increases, in metropolitan areas, and of traffic-related delays for journeys by car within existing road networks. General trends and growth patterns in individual cases over given periods of time are deemed to be of special interest. A comparison or ranking of cities' overall traffic levels and of their infrastructure systems was not the primary objective of this research, since different criteria and constraints impose limits on further evaluation.

A fluorescence-based, gain-of-signal, live cell system to evaluate SARS-CoV-2 main protease inhibition (2021)

The likelihood of continued circulation of COVID-19 and its variants, and novel coronaviruses due to future zoonotic transmissions, combined with the current paucity of coronavirus antivirals, emphasize the need for improved screening in developing effective antivirals for the treatment of infection by SARS-CoV-2 (CoV2) and other coronaviruses. Here we report the development of a live-cell based assay for evaluating the intracellular function of the critical, highly-conserved CoV2 target, the Main 3C-like protease (Mpro). This assay is based on expression of native wild-type mature CoV2 Mpro, the function of which is quantitatively evaluated in living cells through cleavage of a biosensor leading to loss of fluorescence. Evaluation does not require cell harvesting, allowing for multiple measurements from the same cells facilitating quantification of Mpro inhibition, as well as recovery of function upon removal of inhibitory drugs. The pan-coronavirus Mpro inhibitor, GC376, was utilized in this assay and effective inhibition of intracellular CoV2 Mpro was found to be consistent with levels required to inhibit CoV2 infection of human lung cells. We demonstrate that GC376 is an effective inhibitor of intracellular CoV2 Mpro at low micromolar levels, while other predicted Mpro inhibitors, bepridil and alverine, are not. Results indicate this system can provide a highly effective high-throughput coronavirus Mpro screening system.
On the Radical Cation Spectra of Fullerenes and Fulleranes. Part 2: C60H36, C70H38, C60H18and C60Hx/C70HyMixture (2012)

A series of fulleranes, namely C60H36, C70H38, C60H18 and a mixture of hydrogenated fullerenes composed by 77% C60Hx and 22% C70Hy, were dissolved in oleum (fuming sulfuric acid) in order to record the radical cation spectra of these molecules. Surprisingly, it was found that the fulleranes spectra in oleum corresponded to the radical cation spectra of pristine C60 and C70 fullerenes. Therefore, it was concluded that the fulleranes in a high ionizing and oxidizing medium such as oleum are dehydrogenated and oxidized to C60 +• and C70 +•. The prolonged contact with oleum leads to multiple sulfonation of the radical cations.
Closure to “Discussion of ‘Friction Between High Speed Gear Coupling Teeth’” (1981, ASME J. Mech. Des., 103, pp. 59–60) (1981)

There are three solutions to improve the performance of high speed couplings:a. Cool the oil just before it enters the couplings.b.Use a high viscosity oil in a separate lube circuit.c.Use a very high viscosity lubricant in a lube packed coupling.
Atrioventricular Conduction Disturbance Characterization in Transcatheter Aortic Valve Implantation With the CoreValve Prosthesis (2011)

CoreValve implantation worsens AV conduction in most patients, either transiently or permanently. This worsening is the result of direct damage either on the His bundle or on the AV node.

Effect of cimetidine and ranitidine on drug induced damage to gastric epithelial cell monolayers in vitro. (1989)

The effect of the H2 blockers cimetidine and ranitidine on drug induced damage to gastric cell monolayers has been evaluated in conditions independent of systemic factors and their anti-acid properties. Monolayers of mucous cells from a human cell line MKN 28, obtained from a human gastric adenocarcinoma, have been studied. Cell damage has been assessed qualitatively by trypan blue dye exclusion test and quantitatively by 51Cr release assay. Cimetidine and ranitidine significantly protected cultured cells against damage induced by sodium taurocholate decreasing taurocholate induced 51Cr release by 36% (p less than 0.001) and 28% (p less than 0.01), respectively. Cimetidine was also protective in concentrations lower than ranitidine. This protection was not prevented by the prostaglandin synthesis inhibitor indomethacin nor by the sulph-hydryl blocker N-ethylmaleimide. Incubation with cimetidine and ranitidine did not increase the production of PGE2 by cultured cells nor did it affect the cellular level of sulph-hydryl compounds. Cimetidine and ranitidine did not afford protection against damage induced by indomethacin and ethanol. Cimetidine in a concentration of 10 4M increased ethanol induced damage significantly. In conclusion (1) cimetidine and ranitidine protect gastric cells against taurocholate induced damage in vitro, independently of their anti-acid effect; (2) this protection is not mediated by prostaglandin E2 or sulph-hydryl compounds; (3) cimetidine and ranitidine do not protect gastric cells against damage induced by indomethacin and ethanol.
Coherent optical receiver with widely tunable local oscillator laser (2007)

Recently, there has been a renewed interest in coherent optical detection. The reasons for this are: a) coherent optical receivers achieve high receiver sensitivities; b) multilevel modulation formats can be detected very efficiently; c) optical WDM systems with high spectral efficiency can be implemented; and d) preservation of the optical phase allows electrical equalizers to efficiently compensate optical channel impairments. These advantages of coherent optical detection over direct detection can be used to overcome some of the obstacles that limit the data capacity and the reach of current direct detection systems, both fiber and free-space based. The essential part of the coherent optical receiver is the optical local oscillator (LO) laser. It has to provide a high optical output power with low linewidth and low relative intensity noise (RIN). With a widely tunable LO laser a frequency-agile receiver can be constructed. To determine the best candidates for tunable LO lasers, different laser technologies are discussed in terms of output power, power variation, electrical power dissipation, switching time, control leads, package dimensions, tuning range, linewidth and RIN. A heterodyne receiver to detect 2.5 Gb/s and 10 Gb/s signals has been implemented with a standard distributed feed back (DFB) laser. Upgrades of the coherent receiver with a widely tunable LO will be presented. Experimental comparison of the LO lasers and their impact on the receiver sensitivity will be shown.
The 5′ RNA Terminus of Spleen Necrosis Virus Contains a Novel Posttranscriptional Control Element That Facilitates Human Immunodeficiency Virus Rev/RRE-Independent Gag Production (1999)

Previous work has shown that spleen necrosis virus (SNV) long terminal repeats (LTRs) are associated with Rex/Rex-responsive element-independent expression of bovine leukemia virus RNA and supports the hypothesis that SNV RNA contains a cis-acting element that interacts with cellular Rex-like proteins. To test this hypothesis, the human immunodeficiency virus type 1 (HIV) Rev/RRE-dependent gag gene was used as a reporter to analyze various SNV sequences. Gag enzyme-linked immunosorbent assay and Western blot analyses reveal that HIV Gag production is enhanced at least 20, 000-fold by the 5' SNV LTR in COS, D17, and 293 cells. Furthermore, SNV RU5 in the sense but not the antisense orientation is sufficient to confer Rev/RRE-independent expression onto a cytomegalovirus-gag plasmid. In contrast, the SNV 3' LTR and 3' untranslated sequence between env and the LTR did not support Rev-independent gag expression. Quantitative RNase protection assays indicate that the SNV 5' RNA terminus enhances cytoplasmic accumulation and polysome association of HIV unspliced and spliced transcripts. However, comparison of the absolute amounts of polysomal RNA indicates that polysome association is not sufficient to account for the significant increase in Gag production by the SNV sequences. Our analysis reveals that the SNV 5' RNA terminus contains a unique cis-acting posttranscriptional control element that interacts with hypothetical cellular Rev-like proteins to facilitate HIV RNA transport and efficient translation.

Incidental renal tumor diagnosis offers better prognosis, providing longer disease-free survival.
Pathology of Multiple Sclerosis (2012)

Pathological examination of the affected human tissue is key to understanding the possible mechanisms operating in the disease. In multiple sclerosis (MS), studies of central nervous system (CNS) tissues reveal the inflammatory nature of the disease associated with demyelination and axonal damage. Based on the concept of a pathogenic adaptive immune response, immunosuppressive therapies have been developed in an attempt to block or inhibit the potentially pathogenic T and B cells. More recently, re-examination of the neuropathology has led to a resurgence of interest in the neurodegenerative aspects of the disease, the involvement of cortical damage as well as the role of innate immunity in MS. These ideas have led to paradigm shifts from MS being the result of autoimmunity to myelin due to initial adaptive immune responses, to that of a neurodegenerative disease in which, besides T and B cells, innate immunity may play a major role in the disease process. The neuropathological studies have undoubtedly influenced pharmaceutical interest in development of neuroprotective approaches. Here we review the latest findings from pathological studies of MS tissues and discuss the relevance of these findings for future therapeutic approaches.
