Sufficient Conditions for Fast Switching Synchronization in Time Varying Network Topologies

In previous work, empirical evidence indicated that a time-varying network could propagate sufficient information to allow synchronization of the sometimes coupled oscillators, despite an instantaneously disconnected topology. We prove here that if the network of oscillators synchronizes for the static time-average of the topology, then the network will synchronize with the time-varying topology if the time-average is achieved sufficiently fast. Fast switching, fast on the time-scale of the coupled oscillators, overcomes the descychnronizing decoherence suggested by disconnected instantaneous networks. This result agrees in spirit with that of where empirical evidence suggested that a moving averaged graph Laplacian could be used in the master-stability function analysis. A new fast switching stability criterion here-in gives sufficiency of a fast-switching network leading to synchronization. Although this sufficient condition appears to be very conservative, it provides new insights about the requirements for synchronization when the network topology is time-varying. In particular, it can be shown that networks of oscillators can synchronize even if at every point in time the frozen-time network topology is insufficiently connected to achieve synchronization.Comment: Submitted to SIAD

Naturalisasi Transgender dalam Film Lovely Man

Film merupakan salah satu media massa yang digunakan untuk menyampaikan pesan dan ideologi ke masyarakat. Film merepresentasikan beberapa kejadian di dunia nyata.Film Lovely Man adalah film yang menggambarkan naturalisasi transgender.Kehidupan transgender sama seperti kehidupan masyarakat dominan, tidak ada yang berbeda. Heteronormativitas tidak memberikan ruang gerak yang bebas bagi gender lain selain dua gender dominan, yakni laki-laki dan perempuan. Terdapat 26 leksia dalam penelitian ini, dari leksia dipilih berdasarkan tujuan penelitian.Tujuan penelitian ini adalah bagaimana teks film Lovely Man dalam melakukan naturalisasi transgender dan mengetahui nilai-nilai dalam kultur dominan (heteronormatif) dalam film Lovely Man.Pada penelitian ini menggunakan pendekatan kualitatif dengan analisis semiotika Roland Barthes secara sintagmatik dan paradigmatik. Pada analisis paradigmatik menggunakan lima kode pokok pembacaan teks dari Roland Barthes. Naturalisasi dapat dilihat melalui makna sintagmatik dan paradigmatik dengan menunjukkan bahwa tokoh waria dalam film ini juga memiliki relasi hubungan keluarga yang normal sama seperti keluarga heteroseksual lain. Mitos dan ideologi membangun dan menaturalkan intepretasi tertentu secara khas dan historis dengan menunjukkan ikatan emosional antara ayah dan anak, panggilan orang tua “bapak” dan hubungan antara ayah dan anak. Panggilan “bapak” menunjukkan pada film ini ingin meleburkan status seorang bapak tidak hanya dilihat dari sisi biologisnya saja, tapi dilihat dari perannya sebagai seorang ayah. Namun disisi lain, film ini tidak bisa lepas dari heteronormativity yang ada. Waria masih terbelenggu dalam gender yang mereka yakini yakni transgender, namun dalam perannya sebagai pekerja seksual waria harus berperan sebagai peran feminin. Merubah bentuk tubuh dengan melakukan operasi plastik dengan menunjukkan adanya peran laki-laki dan wanita salah satu bentuk dalam teks film yang tidak bisa melepaskan heteronormativity

Nano-porosity in GaSb induced by swift heavy ion irradiation

Nano-porous structures form in GaSb after ion irradiation with 185 MeV Au ions. The porous layer formation is governed by the dominant electronic energy loss at this energy regime. The porous layer morphology differs significantly from that previously reported for low-energy, ion-irradiated GaSb. Prior to the onset of porosity, positron annihilation lifetime spectroscopy indicates the formation of small vacancy clusters in single ion impacts, while transmission electron microscopy reveals fragmentation of the GaSb into nanocrystallites embedded in an amorphous matrix. Following this fragmentation process, macroscopic porosity forms, presumably within the amorphous phase.The authors thank the Australian Research Council for support and the staff at the ANU Heavy Ion Accelerator Facility for their continued technical assistance.

Understanding the Relationship between Genetic Markers and Skeletal Remains: Implications for Forensic Anthropology and Phenotype-Genotype Studies

Human identification techniques have been a leading tool to hold perpetrators accountable, give families closure, and reconstruct faces on skulls. This project is a pilot study to critically examine three disciplines that fall under the human identification umbrella: forensic anthropology, forensic genetics, and forensic art. Current facial research in genetics focuses on data from living individuals where specific single-nucleotide polymorphisms (SNPs) that influence specific regions of the face have been found. This study assesses the translation of these same regions to craniometric dimensions (inter-landmark distances) of the underlying skull itself. The goal of this project is to provide information regarding the correlation of craniometric measurements and SNPs, as well as encourage interdisciplinary work within the forensic sciences. We examined a selection of candidate SNPs currently identified in the literature to determine if there were correlations between inter-landmark distances and those SNPs within the same individual. A series of 98 craniometric landmarks were collected from 17 documented skulls from the Texas State Donated Skeletal Collection using a 3D Microscribe digitizer. Criteria for inclusion in this study included European American ancestry, the presence of intact skulls, and presence of associated donor blood cards collected at the time of body donation. Using these blood samples, DNA from each individual was extracted, amplified, and sequenced through Next Generation Sequencing for the specific chosen SNPs. Afterward, bioinformatics tests were applied to observe the presence or absence of the major or minor alleles in the specific locations on the genome. After determining the presence or absence of an SNP (minor allele), a set of statistical tests were performed including: Spearman’s correlation between the craniometric measurements and the individual’s genetic data variables; two-way hierarchical clustering and Bootstrap Forest modelling between variables that demonstrated significant correlation; a principal component analysis was performed on the craniometric data (inter- landmark measurements) and genetic data (SNP presence/absence) in order to check the homogeneity of each data set; and finally, a pair-wise Procrustes analysis was completed on the correlation of the two data sets as different groups. The results indicate a correlation in various degrees between the targeted craniofacial regions and the targeted SNPs. There were 11 SNPs that showed significant correlation (p \u3c0.05). However, the correlations were not as expected and showed some interesting results. By group level there was no significant correlation, however, there was correlation at the individual level. While some SNPs affected the soft tissues only, others showed correlations with the skull (hard tissue), a finding that had not been previously known. By combining craniometric and DNA analyses to leverage genotype-phenotype associations, there is great potential to expand the discourse of current facial approximation and to, thereby, provide new investigative tools for human identification in forensic anthropology

Sawah Baru Landscape Identification for Agroedutourism Agriculture 4.0, A Community-Based Development Project

IPB University has adequate agricultural land facilities and infrastructure for education and research activities. It has the potential to be developed into an agricultural area 4.0 for agrotourism activities, one of which is in the landscape of the Babakan Education Garden or Farm Teaching Sawah Baru located in Babakan Village, Dramaga District, Bogor Regency. This study aims to identify the character of the Sawah Baru landscape for the development of community-based agricultural agrotourism 4.0. The analysis used in this study used direct observation of the field and the literature study method. The identification of several aspects in the field is carried out using drones to obtain aerial photos, which are then processed using software to produce orthophotos and continue to digitize the boundaries of the research location using spatial analyst tools. The stages of identifying new rice field landscapes for the development of community-based agricultural agrotourism 4.0 include several stages, namely the preparation and inventory stages. The results of the identification of several aspects consisting of landscape sustainability, potential tourist attraction and tourism-supporting potential show that in terms of landscape sustainability, the criteria of each existing aspect are excellent and suitable to be developed into tourist destinations. Regarding potential tourist destinations, the study area presents aspects that have the potential to attract visitors. Finally, regarding tourism-supporting potential, Sawah Baru has tourism-supporting aspects that are quite adequate to meet the needs of tourism activities. However, there is still a need to create additional facilities and utilities that can support user activity on the site.

The emergence of synaesthesia in a Neuronal Network Model via changes in perceptual sensitivity and plasticity

Synaesthesia is an unusual perceptual experience in which an inducer stimulus triggers a percept in a different domain in addition to its own. To explore the conditions under which synaesthesia evolves, we studied a neuronal network model that represents two recurrently connected neural systems. The interactions in the network evolve according to learning rules that optimize sensory sensitivity. We demonstrate several scenarios, such as sensory deprivation or heightened plasticity, under which synaesthesia can evolve even though the inputs to the two systems are statistically independent and the initial cross-talk interactions are zero. Sensory deprivation is the known causal mechanism for acquired synaesthesia and increased plasticity is implicated in developmental synaesthesia. The model unifies different causes of synaesthesia within a single theoretical framework and repositions synaesthesia not as some quirk of aberrant connectivity, but rather as a functional brain state that can emerge as a consequence of optimising sensory information processing

PERENCANAAN LANSKAP WISATA PANTAI TANJUNG BARU BERBASIS ECO-LANDFORM

ABSTRACTBeach landform is geographically formed by sand and located in sea shore. Land use change of mangrove forest into embankment and the development of tourism in Tan-jung Baru Beach has lead to the occurrence of enviromental degradation in this area. This research was aimed to identify and analyze bio-physical condition, and also to propose landscape planning concept and development toward the ecologycal landform based tourism planning. The method used in this research refers to ecological approach with the planning stages by Gold (1980). That method consists of preparation, inven-tory, analysis, synthesis, and landscape planning. Descriptive and spatial analyze were used to determine the quality ecology and tourism aspects. Spatial analysis of these aspects is use to determine the quality of ecology and tourism area of Tanjung Baru Beach. The result of this research shows that there are 4 quality categories of ecology aspect which are worst, less, rare, and good. The tourism aspect found that the category is the same as in ecology aspect. The proposed recommendation is focused on conservation and rehabilition of mangrove forest as ecological based tourism planning.Keywords: Ecology, Landform, Beach, Tourism, Landscape Plannin

Altered processing of sensory stimuli in patients with migraine

Migraine is a cyclic disorder, in which functional and morphological brain changes fluctuate over time, culminating periodically in an attack. In the migrainous brain, temporal processing of external stimuli and sequential recruitment of neuronal networks are often dysfunctional. These changes reflect complex CNS dysfunction patterns. Assessment of multimodal evoked potentials and nociceptive reflex responses can reveal altered patterns of the brain's electrophysiological activity, thereby aiding our understanding of the pathophysiology of migraine. In this Review, we summarize the most important findings on temporal processing of evoked and reflex responses in migraine. Considering these data, we propose that thalamocortical dysrhythmia may be responsible for the altered synchronicity in migraine. To test this hypothesis in future research, electrophysiological recordings should be combined with neuroimaging studies so that the temporal patterns of sensory processing in patients with migraine can be correlated with the accompanying anatomical and functional changes
