Implementing Hierarchical Indoor Semantic Location Identity Classification: A Case Study for COVID-19 Proximity Tracking in the Philippines

Efforts toward COVID-19 proximity tracking in closed environments focus on efficient proximity identification by combining it with indoor localization theory for location activity monitoring and proximity detection. But these are met with concerns based on existing considerations of the localization theory like costly infrastructure, multi-story support, and over-reliance on sensor networks. Semantic location identities (SLI), or location data stored with additional meaningful context, has become a feasible localizing factor especially in locations that have multiple spaces with different usage from each other. There is also a novel method of classification framework, called hierarchical classification, that leverages the hierarchical structure of the labels to reduce model complexity. The research aims to provide a solution to proximity analysis and location activity monitoring considering guidelines released in a Philippine context that addresses concerns of indoor localization and handling of geospatial data by implementing a hybrid hierarchical indoor semantic location identity classification that focuses on observable events within context-unique locations.

THE HISTORICAL DEVELOPMENT OF THE STUDY OF BROCA'S APHASIA

Broca's aphasia is a type of aphasia named after the French surgeon Broca. Broca's aphasic patients experienced difficulty in speaking, but they could understand both spoken and written language. There were three essential patients in the historical development of the study of Broca's aphasia. Louis Victor Leborgne (1809–1861) was also known as Monsieur Leborgne or 'Tan' as he could only utter the syllable 'Tan' throughout his 21 years of illness. The second patient was called Lazare Lelong. His language ability was slightly better than Leborgne. He could utter simple syllables, such as oui (yes), non (no), and this (trois or three). The third patient was Gage, a railway company worker. Broca studied similar cases in the following years and planned a brain function localization theory.

DINAMIKA TERORISME DI INDONESIA STUDI TENTANG LOKALISASI IDEOLOGI EKSTERNAL

AbstrakThe terrorism movement in Indonesia has developed from time to time. It perceived when comparing the perceptions of The Indonesian Islamic State from each group. Darul Islam, the root of the extremism movement, echoed the narrative of jihad against the colonialist. They believed that theocracy was an ideal state construction amidst the disappointing policies of the Central Government at the beginning of independence. In the meantime, the perception of Jemaah Islamiyah towards an Islamic state was full of Salafi nuances because they believed that its establishment as an obligation for every Muslim. Meanwhile, Jemaah Ansharul Daulah noticed The Indonesian Islamic State as only part of a global caliphate. The author argues that this dynamic is caused by the phenomenon of ideological internalisation. By combining localization theory and ideological concepts, this article concluded that the ideological localization of external radicalism occurred for three reasons, namely moral compliance to adopt a more argumentative ideology, rational calculations of strategies that can be implemented in the local context and temporary strategies to maintain group existence.

Квантовая когерентность и эффект Кондо в двумерном электронном газе магнитно-нелегированных гетероструктур AlGaN/GaN

The unusual observation of the Kondo effect in the two-dimensional electron gas (2DEG) of magnetically undoped AlGaN/GaN heterostructures is reported. The temperature-dependent zero-field resistivity data exhibits an upturn below 120 K, while the standard low-temperature weak localization and then weak antilocalization behaviour is revealed at T → 0. Magnetic transport investigations of the system are performed in the temperature range of 0.1–300 K and at magnetic fields up to 8 T, applied perpendicularly to the 2DEG plane. The experimental data are analyzed in terms of the multichannel Kondo model for d _0 magnetic materials and weak localization theory taking into account the spin-orbit interaction.

Topological insulators and the Kane–Mele invariant: Obstruction and localization theory

We present homotopy theoretic and geometric interpretations of the Kane–Mele invariant for gapped fermionic quantum systems in three dimensions with time-reversal symmetry. We show that the invariant is related to a certain 4-equivalence which lends it an interpretation as an obstruction to a block decomposition of the sewing matrix up to non-equivariant homotopy. We prove a Mayer–Vietoris Theorem for manifolds with [Formula: see text]-actions which intertwines Real and [Formula: see text]-equivariant de Rham cohomology groups, and apply it to derive a new localization formula for the Kane–Mele invariant. This provides a unified cohomological explanation for the equivalence between the discrete Pfaffian formula and the known local geometric computations of the index for periodic lattice systems. We build on the relation between the Kane–Mele invariant and the theory of bundle gerbes with [Formula: see text]-actions to obtain geometric refinements of this obstruction and localization technique. In the preliminary part we review the Freed–Moore theory of band insulators on Galilean spacetimes with emphasis on geometric constructions, and present a bottom-up approach to time-reversal symmetric topological phases.

The history of neurosurgery

The history of neurosurgery falls naturally into the premodern era, where it is essentially the history of surgery to the skull and of head injuries, and the modern era, where it is the history of surgery to the brain itself, made possible by cerebral localization theory, antisepsis, and anaesthesia, all of which developed in the nineteenth century. The first known neurosurgical procedures were skull trephines, seemingly carried out on both the living and the dead. It is unclear whether these were performed for therapeutic or ritualistic reasons. There are many trepanned skulls dating back thousands of years to the Neolithic era, and perhaps to even earlier, from sites all over the world.
