We investigate magnetoplasmon dynamics localized on the edges of graphene vortex Hall fluid. The vortex matter captures an anomalous term that causes vortex localization near fluid boundary and creates a double boundary layer, Δ0∝(β-1)lB with β being filling factor. The term also has qualitative effect on resonant excitations of edge magnetoplasmons. We found that, for sharp edges under experimental conditions, graphene edge magnetoplasmon (EMP) resonances have similar behavior as in recent experiments. Gradual distinctions arise for smooth edges in the presence of the anomalous term, where a weak EMP peak appears. The second peak becomes well noticed as the smoothness is increased. We identified the resonant mode as an Inter-EMP. It originates from the oscillations of charges in the inner boundary of the double layer. The present observation brings to light the direct cause of Inter-EMP which remained to be detected in graphene experiments.

SummaryThis study investigated the difference of [Ca2+]i movement in platelets in response to thrombin and TRAP. The involvement of αIIbβ3 in this signaling was also studied. Stimulation of platelets with thrombin at 0.03 U/ml caused platelet aggregation and a two-peak increase in [Ca2+]i. The second peak of [Ca2+]i, but not the first peak was abolished by the inhibition of platelet aggregation with αIIbβ3 antagonists or by scavenging endogenous ADP with apyrase. A cyclooxygenase inhibitor, aspirin, and a TXA2 receptor antagonist, BM13505, also abolished the second peak of [Ca2+]i but not the first peak, although these regents did not inhibit aggregation. Under the same assay conditions, measurement of TXB2 demonstrated that αIIbβ3 antagonists and aspirin almost completely inhibited the production of TXB2. In contrast to thrombin-stimulation, TRAP caused only a single peak of [Ca2+]i even in the presence of platelet aggregation, and a high level of [Ca2+]i increase was needed for the induction of platelet aggregation. The inhibition of aggregation with αIIbβ3 antagonists had no effect on [Ca2+]i change and TXB2 production induced by TRAP. Inhibition studies using anti-GPIb antibodies suggested that GPIb may be involved in the thrombin response, but not in the TRAP. Our findings suggest that low dose thrombin causes a different [Ca2+]i response and TXA2 producing signal from TRAP. Endogenous ADP release and fibrinogen binding to αIIbβ3 are responsible for the synthesis of TXA2 which results in the induction of the second peak of [Ca2+]i in low thrombin- but not TRAP-stimulated platelets.

The centerpiece of New York State’s 150th anniversary of the Sullivan Expedition of 1779 was a pageant, the “Pageant of Decision.” Major General John Sullivan’s Revolutionary War expedition was designed to eliminate the threat posed by Iroquois allied with the British. It was a genocidal operation that involved the destruction of over forty Indian villages. This article explores the motivations and tactics of state officials as they endeavored to engage the public in this past in pageant form. The pageant was widely popular, and served the state in fixing the expedition as the end point in settler-Indian relations in New York, removing from view decades of expropriations of Indian land that occurred well after Sullivan’s troops left.

Pantai merupakan daerah yang sangat dinamis untuk berubah seiring bertambahnya waktu. Salah satu perubahan yang terjadi di daerah pantai yaitu perubahan pada garis pantai. Tujuan penelitian ini yaitu untuk mengetahui tingkat perubahan garis pantai di pesisir Kecamatan Sayung, Kabupaten Demak dari hasil overlay citra satelit Landsat. Penelitian ini diharapkan dapat berguna sebagai rujukan penelitian selanjutnya, serta sebagai informasi untuk instansi-instansi terkait dan pemerintah agar dapat memperhatikan kondisi keseimbangan fisik pantai di Pesisir Sayung. Penelitian ini menggunakan data yang bersumber dari citra Landsat 7 dan 8 dalam kurun waktu 10 tahun dari tahun 2006 sampai 2016. Metode yang digunakan yaitu metode deskriptif dengan menjelaskan masalah yang terjadi pada lokasi penelitian dengan pendekatan pemodelan dan sistematis. Metode analisis perubahan garis pantai dilakukan dalam program Digital Shoreline Analysis System (DSAS) dengan pendekatan statistik End Point Rate (EPR) dan Net Shorline Movement (NSM). Hasil penelitian menunjukkan bahwa perubahan garis pantai di pesisir Sayung didominasi dengan kejadian abrasi yang sangat tinggi dengan luasan abrasi bernilai 116,48 hektar. Abrasi maksimum terjadi di Desa Timbulsloko, Abrasi minimum terjadi di Desa Sriwulan, Akresi maksimum terjadi di Desa Sriwulan, dan Akresi minimum terjadi di Desa Bedono.
