Abstrak Shape Memory Alloy (SMA) adalah salah satu jenis aktuator yang sedang banyak dipelajari pada aplikasi skala mikro dan nano. Namun di sisi lain, pengembangan pengendalian dalam skala ini masih perlu pengembangan dan penelitian lebih lanjut. Artikel ini mempresentasikan hasil evaluasi tanggapan pergerakan kendali kalang tertutup dari TiNi SMA dalam bentuk spring yang dikendalikan kompensa...

We have used diabetic autonomic neuropathy as a model of chronic pulmonary denervation to study the ventilatory response to incremental exercise in 20 diabetic subjects, 10 with (Dan+) and 10 without (Dan-) autonomic dysfunction, and in 10 normal control subjects. Although both Dan+ and Dan- subjects achieved lower O2 consumption and CO2 production (VCO2) than control subjects at peak of exerci...

To present the application of the XOR Theorem to learning theory we rst give the following two de nitions. Let F be a class of boolean functions and let > 0. A strong learning algorithm for F over the uniform distribution queries the function f : f0; 1gn ! f0; 1g and outputs, with probability at least 1 , a circuit C such that Pr[f(x) 6= C(x)] < 1 nO(1) where Pr is the uniform distribution. The...

Neuroimaging studies have identified two major large-scale brain networks, the default mode network (DMN) and the dorsal attention network (DAN), which are engaged for internally and externally directed cognitive tasks respectively, and which show anticorrelated activity during cognitively demanding tests and at rest. We identified these brain networks using independent component analysis (ICA)...

Normal aging is associated with cognitive decline. Evidence indicates that large-scale brain networks are affected by aging; however, it has not been established whether aging has equivalent effects on specific large-scale networks. In the present study, 40 healthy subjects including 22 older (aged 60-80 years) and 18 younger (aged 22-33 years) adults underwent resting-state functional MRI scan...

Anticorrelation between the default network (DN) and dorsal attention network (DAN) is thought to be an intrinsic aspect of functional brain organization reflecting competing functions. However, the effect size of functional connectivity (FC) between the DN and DAN has yet to be established. Furthermore, the stability of anticorrelations across distinct DN subsystems, different contexts, and ti...

Serangga jika mengigit atau menyengat, memasukkan secret air liur atau racun sengat yang dapat menimbulkan reaksi alergis. Jenis reaksi yang ditimbulkan akibat gigitan atau sangatan serangga bagi penderita tertentu sangat bergantung kepada spesies serangga dan macam alergan. Tanda-tanda dan gejala klinis reaksi alergis akibat gigitan atau sengatan serangan dapat berupa gatal-gatal, pembengkakan...

Seorang pasien laki-laki 27 tahun dengan leukemia mielositik kronik dengan pengobatan hidroksi urea yang tidak teratur, datang dengan keluhan benjolan di pangkal paha kiri disertai rasa nyeri tumpul. Pemeriksaan darah menunjukkan lekosit 125.000/mm3 dengan 13% metamielosit, 8% mielosit, 1% promielosit dan 3% sel batang. Biopsi aspirasi jarum halus menunjukkan sebagian besar sel mieloblas dan se...

Introduction One classical hypothesis among many models to explain the etiology and maintenance of insomnia disorder (ID) is hyperarousal. Aberrant functional connectivity among resting-state large-scale brain networks may be the underlying neurological mechanisms of this hypothesis. The aim of current study was to investigate the functional network connectivity (FNC) among large-scale brain ne...
