AbstractIn this paper, a sub-wavelength metal-insulator-metal (MIM) waveguide structure is proposed by using a cross-shape rectangular cavity, of which wings are coupled with two rectangular cavities. Firstly, a cross-shape rectangular cavity is placed between the input and output MIM waveguides. According to the mutual interference between bright and dark modes, three Fano resonant peaks are generated. Secondly, by adding a rectangular cavity on the left wing of the cross shaped one, five asymmetric Fano resonance peaks are obtained. Thirdly, six asymmetric Fano resonance peaks are achieved after adding another cavity on the right wing. Finally, the finite-difference-time-domain (FDTD) method and multimode interference coupled-mode theory (MICMT) are used to simulate and analyze the coupled plasmonic resonant system, respectively. The highest sensitivity of 1 000nm/RIU is achieved.

Cognitive Sophistication

We analyzed the relationship between modern forms of populism and citizen support for exclusive welfare policies and proposals, and we focused on support for left-wing- and right-wing-oriented welfare policies enacted or proposed during the Lega Nord (LN)–Five Star Movement (FSM) government in Italy (2018–2019). In light of the theoretical perspective of political ideology as motivated by social cognition, we examined citizens’ support for the two policies considering adherence to populist attitudes, agreement on the criteria useful to define ingroup membership, and personal values. We also took into account the role of cognitive sophistication in populism avoidance. A total of 785 Italian adults (F = 56.6; mean age = 35.8) completed an online survey in the summer of 2019 based on the following: support for populist policies and proposals, political ideologies and positioning, personal values, and ingroup boundaries. We used correlation and regression analyses. The results highlight the relationships between populism and political conservatism. Populism was related to the vertical and horizontal borders defining the “people”; cognitive sophistication was not a relevant driver. We identified some facilitating factors that could promote adherence to and support for public policies inspired by the values of the right or of the left, without a true ideological connotation.

Herein, we propose a tunable plasmonic sensor with Fano resonators in an inverted U-shaped resonator. By manipulating the sharp asymmetric Fano resonance peaks, a high-sensitivity refractive index sensor can be realized. Using the multimode interference coupled-mode theory and the finite element method, we numerically simulate the influences of geometrical parameters on the plasmonic sensor. Optimizing the structure parameters, we can achieve a high plasmonic sensor with the maximum sensitivity for 840 nm/RIUand figure of merit for 3.9 × 105. The research results provide a reliable theoretical basis for designing high sensitivity to the next generation plasmonic nanosensor.

Intermittent stretch of the anterior latissimus dorsi (ALD) muscle produces fiber hypertrophy without fiber hyperplasia (J. Appl. Physiol. 74: 1893–1898, 1993). This study was undertaken to determine if a progressive increase in load and duration of stretch would induce extremely large muscle fiber areas or if the fibers would reach a critical size before the onset of fiber hyperplasia. Weights ranging from 10 to 35% of the bird's mass were attached to the right wing of 26 adult quail while the left wing served as the intra-animal control. The stretch protocol was as follows: day 1 (10% wt), days 2 and 3 (rest), day 4 (15% wt), days 5–7 (rest), day 8 (20% wt), days 9 and 10 (rest), days 11–14 (25% wt), days 15 and 16 (rest), and days 17–38 (35% wt). Birds were killed after 12, 16, 20, 24, and 28 days of stretch not including rest days. Muscle mass increased 174% (12 days), 196% (16 days), 225% (20 days), 264% (24 days), and 318% (28 days). Muscle length increased 60% (12 days), 34% (16 days), 59% (20 days), 50% (24 days), and 51% (28 days). Mean fiber area increased 111% (12 days), 142% (16 days), 75% (20 days), 90% (24 days), and 39% (28 days). Fiber number, which was measured histologically, increased significantly by 82% only in the 28 days of stretch group. The percentage of slow tonic fibers did not change for any of the time points examined.(ABSTRACT TRUNCATED AT 250 WORDS)

Musical Rhythms

This article investigates the role of music in presidential election campaigns and political movements inspired by theoretical arguments in Henri Lefebvre’s Rhythmanalysis, John Dewey ́s pragmatist rethinking of aesthetics and existing scholarship on the politics of music. Specifically, it explores how musical rhythms and melodies enable new forms of political awareness, participation, and critique in an increasingly polarized Brazil through an ethnomusicological exploration of how left-wing and right-wing movements used music to disseminate politics during the 2018 election that culminated in the presidency of Jair Messias Bolsonaro. Three lessons can be learned. First, in Brazil, music breathes life, energy, and affective engagement into politics—sung arguments and joyful rhythms enrich public events and street demonstrations in complex and dynamic ways. Second, music is used by right-wing and left-wing movements in unique ways. For Bolsonaro supporters and right-wing movements, jingles, produced as part of larger election campaigns, were disseminated through massive sound cars in the heart of São Paulo while demonstrators sang the national anthem and waved Brazilian flags. In contrast, leftist musical politics appears to be more spontaneous and bohemian. Third, music has the ability to both humanize and popularize bolsonarismo movements that threaten human rights and the rights of ethnic minorities, among others, in contemporary Brazil. To contest bolsonarismo, Trumpism, and other forms of extreme right-wing populism, we cannot close our ears and listen only to grooves of resistance and songs of freedom performed by leftists. We must also listen to the music of the right.

Mode 2

This work proposed a multiple mode Fano resonance-based refractive index sensor with high sensitivity that is a rarely investigated structure. The designed device consists of a metal–insulator–metal (MIM) waveguide with two rectangular stubs side-coupled with an elliptical resonator embedded with an air path in the resonator and several metal defects set in the bus waveguide. We systematically studied three types of sensor structures employing the finite element method. Results show that the surface plasmon mode’s splitting is affected by the geometry of the sensor. We found that the transmittance dips and peaks can dramatically change by adding the dual air stubs, and the light–matter interaction can effectively enhance by embedding an air path in the resonator and the metal defects in the bus waveguide. The double air stubs and an air path contribute to the cavity plasmon resonance, and the metal defects facilitate the gap plasmon resonance in the proposed plasmonic sensor, resulting in remarkable characteristics compared with those of plasmonic sensors. The high sensitivity of 2600 nm/RIU and 1200 nm/RIU can simultaneously achieve in mode 1 and mode 2 of the proposed type 3 structure, which considerably raises the sensitivity by 216.67% for mode 1 and 133.33% for mode 2 compared to its regular counterpart, i.e., type 2 structure. The designed sensing structure can detect the material’s refractive index in a wide range of gas, liquids, and biomaterials (e.g., hemoglobin concentration).

Ideological Difference

This article wants to examine how the media ideology about the concept of radicalism in Islam in the mass media of Republika and Koran Tempo. The Republika newspaper supports and agrees to the Islamic Defenders Front (FPI) both with an understanding of the prohibition of homosexuality and the appointment of news of FPI's violence against homosexuals. The Tempo newspaper is more about renewing ideas such as reporting on the views of the Liberal Islam Network (JIL) in respect of homosexuals. Homosexuality is the same sex lover or the choice of sexuality abnormalities is normal as a human being, it does not need to be criticized but must be respected as individual freedom. There is a fundamental ideological difference between Republika and Koran Tempo by renewing the concept of homosexuality with thinking radicalism on the basis of Islamic teachings. The homosexual issue, FPI applies the meaning of Islamic radicalism from the right-wing side which promotes violence as resistance, while JIL applies the meaning of radicalism from the left-wing side which prioritizes the radicalism of thought and law in the Koran.  AbstrakArtikel ini ingin mengkaji bagaimana ideologi media tentang konsep radikalisme dalam Islam di media massa Republika dan Koran Tempo. Surat kabar Republika mendukung dan setuju pada Front Pembela Islam (FPI) baik dengan pemahaman pelarangan homoseksual dan pengangkatan berita tindak kekerasan FPI melawan homoseksual. Koran Tempo lebih pada pembaharuan pemikiran seperti pemberitaan pandangan Jaringan Islam Liberal (JIL) terkait menghormatinya kaum homoseksual. Homoseksual adalah penyuka sesama jenis atau pilihan kelainan seksualitas itu normal sebagai manusia, tidak perlu dicela tapi harus dihargai sebagai kebebasan individu. Terdapat perbedaan ideologi yang mendasar antara Republika dan Koran Tempo dengan melakukan pembaharuan konsep homoseksual dengan radikalisme berpikir dengan pijakan ajaran Islam. Persoalan homoseksual, FPI menerapkan makna radikalisme Islam dari sisi sayap kanan yang mengedepankan kekerasan sebagai perlawanan, sedangkan JIL menerapkan makna radikalisme dari sisi sayap kiri yang mengutamakan keradikalan pemikiran dan hukum dalam al-Quran.

The article examines the cultural forms of legitimation / delegitimation of authority of the Provisional Government. Particular attention is paid to the personal authority of Alexander Kerensky, including rhetorical (persuasive) devices and visual images which underlay the tactics of praising or condemning him. As the main source, the article uses the newspapers of A.A. Suvorin, namely Malen'kaya gazeta [Little newspaper], Narodnaya gazeta [People’s newspaper], Rus' [Rus], Novaya Rus' [New Rus]. These newspapers are compared with resolutions, letters and diaries, and with publications in other periodicals. The study clarifies some aspects of political isolation of the Provisional Government in the fall of 1917. By this time, the propaganda attack on Kerensky was conducted not only by the Bolsheviks and other left-wing groups but also by the right-wing and conservative publications. The propaganda of the left- and right-wing opponents was significantly different but they had a point of contact: both of them created the image of the “traitor” who was unworthy to remain in power.

The purpose of this study was to determined whether fibers in the anterior latissimus dorsi (ALD) muscle from aged Japanese quail have decreased hypertrophic or proliferative responses to 30 days of stretch overload compared with fibers from adult birds. Two groups of quail were studied, 12-wk-old quail (adult; n = 16) and 90-wk-old quail (aged; n = 16). The left wing of each bird was overloaded with a weight corresponding to 10% of the bird's body weight, and the right wing served as the intra-animal control. Quails were killed after 30 days of stretch overload. Total fiber number was quantified by counting all the fibers in a transverse section from the midbelly of the ALD muscle. ALD muscles in aged quails retained the capacity to increase their muscle mass (145%), total fiber number (49%), and fiber cross-sectional area (54%) in response to stretch overload. The ALD muscle in aged quail had a significantly lower increase in muscle mass (33%) and mass corrected for nonmuscle tissue (36%) compared with the ALD from young adult birds. Age had no effect on fiber type distribution shifts with stretch. These results suggest that although muscles in old birds have a substantial ability to adapt to enlarge, stretch-induced hypertrophy is attenuated in muscles from old quail.

Abstract Large birds have evolved an effective wing anatomy and mechanics, enabling airborne mastery of manoeuvres and endurance. For these very reasons, they are difficult to replicate and study. The aim of the present work is to achieve active wing articulations to mimic natural bird flapping towards efficient and agile Unmanned Aerial Vehicles (UAVs). The proposed design, bio-mimicking the black-headed gull, Larus ridibundus, has three active and independent servo-controlled wing joints at the shoulder, elbow and wrist to achieve complex controls. The construction of the wing is realised through a polymeric skin and carbon fibre–epoxy composite spars and ribs. The wing movements (flapping, span reduction and twisting) envelopes of the full-scale robotic gull (Robogull) are examined using the Digital Image Correlation (DIC) technique and laser displacement sensing. Its aerodynamic performance was evaluated in a wind tunnel at various flapping parameters, wind speeds and angles of attack. It is observed that a flapping amplitude of 45 $^\circ$ is more favourable than 90 $^\circ$ for generating higher lift and thrust, while also depending on the presence of span reduction, twist and wind speed. The model performs better at a flying velocity of 4m/s as compared with 8m/s. Both lift and thrust are high at a higher flapping frequency of 2.5Hz. Combined variation of the flapping frequency and stroke ratio should be considered for better aerodynamic performance. The combination of a lower stroke ratio of 0.5 with a flapping frequency of 2.5Hz generates higher lift and thrust than other combinations. Span reduction and wing twist notably and independently enhance lift and thrust, respectively. An increase in the angle-of-attack increases lift but decreases thrust. The model can also generate a significant rolling moment when set at a bank angle of 20 $^\circ$ and operated with independently controlled flapping amplitudes for the wings (45 $^\circ$ for the left wing and 90 $^\circ$ for the right wing). Based on the optimal values for the flapping amplitude (45 $^\circ$ ), flapping frequency (2.5Hz) and flying velocity (4m/s), the Strouhal number (St) of the Robogull model is 0.24, lying in the optimal range ( $0.2 < \mathrm{St} < 0.4$ ) for natural flyers and swimmers.

From its founding, the U.S. government has promoted agriculture, and since the Great Depression, has directly supported farm incomes and crop prices. Franklin Roosevelt’s New Deal programs linked farm subsidies to food assistance for the poor, a politically successful combination then and now. Sarah Ludington describes how the U.S. Department of Agriculture (USDA), through the Farm Bill, became responsible for school lunches, food stamps, and land conservation in addition to billions of dollars in subsidies for commodity crops like corn and cotton. Now a target for both the right wing and left wing of American politics, the Farm Bill continues to embody the tensions at the heart of American agriculture.
