Negative vacuum friction in terahertz gain systems

Two objects in relative motion without physical contact suffer a friction force, resulting from vacuum fluctuation. It is widely accepted that friction acts in the opposite direction of the relative velocity. Here, this study demonstrates the existence of negative friction, where the direction of friction is along the sliding direction, in a gain system. The system consists of a vacuum-separated silica sphere and a dielectric substrate covered by a graphene sheet (gain medium). The friction torque of the rotating sphere can be switched between positive and negative, depending on the quasi-Fermi energy of graphene. Negative vacuum friction can be achieved when the quasi-Fermi energy is large, and its magnitude is strongly dependent on the distance, temperature, and permittivity of the substrate. For moderate conditions, the torque generated by negative friction surpasses the resistance posed by the surrounding air, presenting a different approach for driving nanoparticles to an ultrahigh rotating speed.Received 17 May 2023Accepted 31 May 2023DOI:https://doi.org/10.1103/PhysRevB.108.045406©2023 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasCasimir effectFrictionSurface plasmon polaritonPhysical SystemsGrapheneCondensed Matter, Materials & Applied Physics

Protestos no Brasil: pós-modernidade e midialivrismo com os #jornalistaslivres e #mídianinja

Cyberculture has caused changes in communication processes in the contemporary world, especially in relation to the poles of information production and diffusion, giving significant visibility to free media and post-mass movements, aided by the communication established through portable devices, (Wi-Fi, 3G, 4G) and other digital tools such as social networking sites as well as streaming and collaborative platforms. This new media communication phenomenon, with P2P communication, carries hybrid, convergent and multimedia elements, through which the subjects carry out new media practices and, in this way, put in tension the relations of power in the mediatic ecosystem by acting in Postmodernity post-mass movements, such as midialivrism. In order to understand how this phenomenon occurs, we analyze the configuration of midialivrism (MALINI; ANTOUN, 2013) in a convergent way to social manifestations that have occurred in Brazil since 2013, with the free collectives Mídia NINJA and Jornalistas Livres (Free Journalists), also converging to cyberculture, ruled by the cyberculture laws (LEMOS, 2003). These collectives emerge from this scenario, which mixes cyber-presence activism, providing the basis for reflecting on the points of tension and connection between free-media practices and corporate media, pointing to post-journalism. From the participant observer method, and with the aid of the grounded theory (DIC, 2005), we collect and analyze the material produced by midialivists in cyberculture. Through analysis and interpretation, it resulted in a mapping of a set of midialivist practices. This path made it easier to identify the midialivist's activities in the internet and street networks, and how the three factors (consumption / sharing / production) conditioned each other, ended up connecting, in a demonstration of what this new relationship of free media with Journalism as an alternative media in the mediatized society and how it interacts, in a collaborative way, on the social protest and movements.

Abstract 855: Medication use and ovary cancer risk in the California Teachers Study

Abstract Background: Approximately 21,000 new cases of ovarian cancer are diagnosed in the United States each year. Because inflammation is thought to affect ovarian carcinogenesis, non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin and ibuprofen, and other medications such as acetaminophen and histamine receptor antagonists, may affect the risk of ovarian cancer. However, existing epidemiological evidence on these associations is mixed. Methods: We assessed the relationship between medication use and risk of invasive epithelial ovarian cancer in the California Teachers Study (CTS), a prospective cohort of former or current female public school teachers and administrators in California. Analysis included 104,184 women, of whom 420 were diagnosed with invasive epithelial ovarian cancer during follow-up through December 31, 2007. Self-reported medication use from the baseline CTS questionnaire (1995-1996) was used to classify exposures. Relative risks (RR) and 95% confidence intervals (CI) were obtained using Cox proportional hazards methods. Results: Regular use, defined as at least once a week, of aspirin (RR 0.96; 95%CI 0.76 − 1.19), non-aspirin NSAIDs (RR 1.04; 95%CI 0.80 − 1.30), acetaminophen (RR 1.13; 95%CI 0.85 − 1.50) or histamine receptor antagonists (RR 0.85; 95%CI 0.58 − 1.20) was not associated with ovarian cancer risk. Ovarian cancer risk was not associated with daily use of aspirin (RR 1.04; 95%CI 0.77 − 1.45) or non-aspirin NSAIDs (RR 0.85; 95%CI 0.56 − 1.31) but was associated with daily use of acetaminophen (RR 1.82, 95%CI 1.01 − 2.95), and the latter association persisted after excluding ovarian cancers diagnosed during the first one to five years of follow-up. Two-thirds of the daily acetaminophen users also reported using acetaminophen for more than three years, but there was no association between increasing duration of use and ovarian cancer risk. Conclusion: Our results do not support the hypothesis that these medications reduce the risk of ovarian cancer. Conversely, the finding that daily acetaminophen use was associated with increased risk of ovarian cancer differs from previous studies and may warrant further investigation.

Quantitation of phospholipid analysis using P<sup>32</sup> by a digital computer method in metabolic experiments on niemann‐pick disease

Abstract Methods involving P 32 uptake into cell cultures, quantitative phospholipid analyses and computerized data analyses have been used to investigate the biochemical defect in Niemann‐Pick disease. The results of these analyses indicate a normal synthesis of sphingomyelin, which considering the threefold increase in total sphingomyelin, gives evidence for a decreased ability of cells to catabolize sphingomyelin in Niemann‐Pick disease. These methods are applicable to other lipid storage diseases.

The Importance and Some Problems of English Language Learning

As one of the International languages, English is becoming more and more important in this globalization era. In Indonesia, this language is taught and learnt from Elementary school up to University level. This means that the learners (students) have studied it for more than 10 (ten) years but in fact most of them are not capable of producing the two language skills (speaking and writing) very well. This might happen to the two other skills, listening and reading. Based on the writer’s experience during his teaching, especially to non-English department students, he found that more than 90% of them, their English competence were very poor. This might be caused by some aspects, such as the inconsistency between the spelling and its pronunciation and many other patterns of grammatical structures that were much different from those of Indonesian language and even more complex and sophisticated as well. As a teacher, s/he has to know how to make those two problems simpler and easier to understand. Besides giving them many chances to practice the language being learnt more and more. Finally, it is expected that this method could make the students capable of catching the idea from the teacher easier to understand and make use of it very well in their real practice.

Testing Wagner's law using disaggregated public expenditure data in the case of Greece: 1958-93

The factors that have influenced the growth of public expenditures have been the subject of extensive theoretical and empirical research. The validity of Wagner's law in the case of Greece is tested using disaggregated public expenditure data for the period 1958-93. The methodology employed is that of cointegration and the related notion of error correction. Results reported here suggest that in the case of Greece only the growth of defence expenditure may be explained in terms of Wagner's law.

Automated summaries of serious adverse events in the hepatitis C antiviral long-term treatment against cirrhosis trial

Background Even though adverse event (AE) collection and official accounting are mandatory for clinical trials, there are limited detailed guidelines specifying how to summarize the event for reporting in a timely and expeditious manner. This article details the AE and serious adverse event (SAE) reporting summary developed for a large multi-center National Institutes of Health (NIH)-sponsored clinical trial. Purpose To review and analyze the large volume of AE data reported by 10 sites (806 SAEs and 19,034 AEs from August 2000 to May 2007) the automated SAE summary was developed. It was designed to ensure timeliness and clarity in the complex process of AE review and reporting. Methods The AE and SAE case report forms (CRFs) as well as the automated SAE summary were developed within a database management system developed by the Data Coordinating Center (DCC) which allowed for web-based data entry at the DCC and 10 sites and offered immediate overall and site-specific reports accessible by the DCC, site, and NIH project staff. Results The automated SAE summary pulled data from multiple CRFs to create a succinct and informative summary and allowed for prompt and easy reporting to the regulatory agencies. The summary was adaptable to the needs of reviewers because of the availability of multiple search options.

Shape-Selection of Thermodynamically Stabilized Colloidal\nPd and Pt Nanoparticles Controlled via Support Effects

Colloidal\nchemistry, in combination with nanoparticle (NP)/support\nepitaxial interactions is used here to synthesize shape-selected and\nthermodynamically stable metallic NPs over a broad range of NP sizes.\nThe morphology of three-dimensional palladium and platinum NPs supported\non TiO&lt;sub&gt;2&lt;/sub&gt;(110) was investigated using scanning tunneling\nmicroscopy. Well-defined Pd and Pt NPs were synthesized via inverse\nmicelle encapsulation. The initially spherical NPs were found to become\nfaceted and form an epitaxial relationship with the support after\nhigh-temperature annealing (e.g., 1100 °C). Shape selection was\nachieved for almost all Pd NPs, namely, a truncated octahedron shape\nwith (111) top and interfacial facets. The Pt NPs were however found\nto adopt a variety of shapes. The epitaxial relationship of the NPs\nwith the support was evidenced by the alignment of the cluster’s\nedges with TiO&lt;sub&gt;2&lt;/sub&gt;(110)-[001] atomic rows and was found to\nbe responsible for the shape control. The ability of synthesizing\nthermally stable shape-selected metal NPs demonstrated here is expected\nto be of relevance for applications in the field of catalysis, since\nthe activity and selectivity of NP catalysts has been shown to strongly\ndepend on the NP shape.

Identification of multiple U-turns using gyroscopes: comparative assessment of two methods

The identification of turnings segments during walking trials including the U-turns represents the first preliminary step required for the analysis of gait featuring straights and turns. To this purpose IMU-based methods were developed, however many of them rely on the a-priori knowledge of the number of turns. In this study, we selected two methods and compared them to evaluate their ability to detect the number of turns in continuous gait with multiple U-turns without further assumptions. Gyroscope data were recorded during gait trials performed at different speeds by two groups of subjects (healthy elderly and patients with Parkinson disease). Results show that the method that employs a sensor on the back yields better results than the one making use of a sensor on the ankles.

2595 Efficacy and safety of avalglucosidase Alfa in participants with late-onset pompe disease after 145 weeks’ treatment: phase 3 COMET trial

<h3>Objectives</h3> Report efficacy/safety of avalglucosidase alfa (AVAL) in participants with late-onset Pompe disease in the extended-treatment period (ETP) of COMET (NCT02782741) at 145 weeks from treatment initiation. <h3>Methods</h3> Following a 49-week primary-analysis period (PAP), participants could enter the ETP. 100 participants (age 16–78 years) enrolled in the PAP. <h3>Results</h3> All 51 who received AVAL 20mg/kg every 2 weeks (qow) in the PAP (AVAL-arm) continued this in the ETP. Of 49 who received alglucosidase alfa (ALGLU) 20mg/kg qow in the PAP, 44 entered the ETP switching to AVAL 20mg/kg qow (Switch-arm). Improvement or stabilization trends from Baseline to Week 145 were observed for primary and secondary outcomes of respiratory and motor function. Changes (LS mean[SE]) in upright forced vital capacity%predicted: AVAL-arm, +1.40(1.21); Switch-arm, +1.18(1.32) and 6-minute walk test distance: AVAL-arm, +20.65(9.60)m; Switch-arm, +0.29(10.42)m. Similar trends occurred in other Week-145 outcomes. Treatment-emergent adverse events (AEs) in the ETP occurred in 49(96.1%) AVAL-arm and 43(97.7%) Switch-arm participants. Five discontinued during the ETP for 6 treatment-emergent AEs; 4 treatment-related (ocular hyperemia, erythema [in same participant], urticaria, respiratory distress) and 2 non-treatment-related (acute myocardial infarction, pancreatic adenocarcinoma). In the ETP, 13(25.5%) AVAL-arm and 12(27.3%) Switch-arm participants had treatment-emergent serious AEs (SAEs); 3 and 2 of them, respectively, had treatment-related SAEs. Switch-arm participants showed no safety/immunogenicity-related concerns. <h3>Conclusions</h3> Week 145 results show sustained treatment effect and continued benefit with AVAL beyond the PAP, and stabilization of treatment effect after switching from ALGLU to AVAL, supporting long-term maintenance of clinically meaningful outcomes with AVAL. <b>Funding:</b> Sanofi.

POWERING PREDICTIONS FOR A SURVEYING SHIP (AGS) REPRESENTED BY MODEL 4914.

Tests were conducted on Model 4914, representing the Surveying Ship (AGS), to predict bare-hull resistance and to establish optimum bilge-keel location. Comparison with the corresponding Taylor Standard Series form indicates that at 15 knots the ehp for the bare-hull form is approximately 10 percent higher than the predicted Taylor ehp. Resistance and propulsion tests were also conducted with the model fully appendaged. Test data show that the appendage resistance increased the ehp about 4 1/2 percent at design speed of 15 knots. A speed of approximately 16 knots should be attained at design power of 3000 shp at 200 rpm. (Author)

Farming adaptations in the face of climate change

Abstract Agriculture is one of the most vulnerable sectors to climate change, and in many agricultural communities climate change adaptations by farmers are underway. Farmers’ beliefs about climate change and their experiences with climate change, along with a range of other factors, could influence climate change adaptation. Utilizing a framework which draws from research examining how farmers’ climate change beliefs and experiences affect their adaptation strategies, and research on farm succession and adaptation at the rural–urban interface (RUI), we ask ‘How do climate change beliefs and different farm attributes (particularly the presence of an heir and location at the RUI) affect adaptation strategies?’ Preliminary findings indicate that adaptation varies based on multiple factors, including belief in climate change, the presence of an heir, geographical location and a variety of other farm characteristics and farmer attributes.

A hierarchical oil depot detector in high-resolution images with false detection control

Oil depot detection in high-resolution images is a challenging task due to the complicated background. This paper aims at further investigating this problem and presents an approach to detect oil depots in a hierarchical manner. Firstly, the Ellipse and Line Segment Detector (ELSD) which guards against false positives is applied to detect elliptical arcs in the image. Afterwards, the Histograms of Oriented Gradient (HOG) are extracted based on the elliptical arc candidates and input into the AdaBoost classifier in order to get the detection of oil tanks. Finally, the Depth-First-Search (DFS) is used to cluster the detection of oil tanks and determine the final oil depot area. Experimental results on real database indicate that the hierarchical algorithm is robust under complicated background and shows good performance against false positives.

Ankle-Brachial Index as a Predictor of Cardiovascular Risk in Atrial

Objectives: Atrial Fibrillation (AF), the most frequent sustained arrhythmia, is associated with a high rate of morbidity and mortality. The clinical course of AF is often complicated by cardiovascular and cerebrovascular adverse events that usually have a dual origin: cardio embolic and atherothrombotic. The aim of our study is to demonstrate the existence of a relationship between Systemic Atherosclerosis and AF. More specifically, we have analysed the prevalence of lower limb Peripheral Artery Disease (PAD) in a population of fibrillating patients, and we have assessed whether the coexistence of AF and PAD might result in increased cardiovascular risks. Methods: The study has been conducted on 200 patients, consecutively engaged, divided into patients with and without AF. All patients were subjected to a cardiovascular risk profile evaluation, a measurement of Ankle-BrachialIndex (ABI), and an estimation of the prevalence of cerebrovascular and cardiovascular events. Results: The obtained results showed that the prevalence of PAD is higher in patients with AF, and these patients have also shown a higher prevalence of cerebrovascular and cardiovascular events. In addition, stratifying cases and controls according to the presence of PAD, we showed that there’s a higher prevalence of cardiovascular and cerebrovascular adverse events in people with both conditions associated. Conclusions: The results affirm that patients with a history of AF have a higher rate of cerebrovascular disease, and patients with PAD and AF have a higher rate of coronary disease, suggesting that measurements of ABI and diagnosis and search for AF should be encouraged.
