--- Localization is widely used in Wireless Sensor Networks (WSNs) to identify the current location of the sensor nodes. A WSN consist of thousands of nodes that make the installation of GPS on each sensor node expensive and moreover GPS may not provide exact localization results in an indoor environment. Manually…

'Marek Neruda' 'Filip Benes' 'Jiri Svub'] This paper deals with the issue of mobile device localization in the environment of buildings, which is suitable for use in healthcare or crisis management. The developed localization system is based on wireless Local Area Network (LAN) infrastructure (commonly referred to as…

— Sensor nodes are low cost, low power devices that are used to collect physical data and monitor environmental conditions from remote locations. Wireless Sensor Networks (WSN's) are collection of sensor nodes, coordinating among themselves to perform a particular task. Localization is defined as the deployment of the…

— Localization is a fundamental task for sensor networks. Traditional network construction approaches allow to obtain localized networks requiring the nodes to be at least tri-connected (in 2D), i.e., the communication graph needs to be globally rigid. In this paper we exploit, besides the information on the neighbors…

Fifth generation (5G) networks providing much higher bandwidth and faster data rates will allow connecting vast number of static and mobile devices, sensors, agents, users, machines, and vehicles, supporting Internet-of-Things (IoT), real-time dynamic networks of mobile things. Positioning and location awareness will…

Localization in Wireless Sensor Networks (WSNs) has been an active topic for more than two decades. A variety of algorithms were proposed to improve the localization accuracy. However, they are either limited to two-dimensional (2D) space, or require specific sensor deployment for proper operations. In this paper, we…

Local translation allows a spatial control of gene expression. Here, we performed a dual protein/mRNA localization screen, using smFISH on 523 human cell lines expressing GFP-tagged genes. A total of 32 mRNAs displayed specific cytoplasmic localizations, and we observed local translation at unexpected locations…

'Chittibabu Guda'] LocSigDB ([http://genome.unmc.edu/LocSigDB/]()) is a manually curated database of experimental protein localization signals for eight distinct subcellular locations; primarily in a eukaryotic cell with brief coverage of bacterial proteins. Proteins must be localized at their appropriate subcellular…

'Rajagopal Subramanyam'] Localization of activity is ubiquitous in life, and also within sub-cellular compartments. Localization provides potential advantages as different proteins involved in the same cellular process may supplement each other on a fast timescale. It might also prevent proteins from being active in…

Near-field localization has attracted significant attention in recent years due to the move toward higher frequencies and extremely large aperture arrays, which expand the near-field region and bring many sources into it. This implies that antenna arrays can be used to localize not only in angle but also in range.…

mRNA localization serves key functions in localized protein production making it critical that the translation machinery itself is present at these locations. Here we show that translation factor mRNAs are localized to distinct granules within yeast cells. In contrast to many mRNP granules, such as P-bodies and stress…

'Dimitrios Pliatsios' 'Konstantinos Ntontin' 'Panagiotis Sarigiannidis' 'Symeon Chatzinotas' 'Marco Di Renzo'] Abstract—When fully implemented, sixth generation (6G) wireless systems will constitute intelligent wireless networks that enable not only ubiquitous communication but also high-accuracy localization services.…

Ultrasound localization microscopy (ULM) is an emerging super-resolution imaging technique for deep tissue microvascular imaging. However, conventional localization methods are constrained by low microbubble (MB) concentration, as accurate localization requires a strict separation of MB point spread functions (PSFs).…

'Mohamed F. Younis'] Localization is a key technology in wireless sensor networks. Faced with the challenges of the sensors’ memory, computational constraints, and limited energy, particle swarm optimization has been widely applied in the localization of wireless sensor networks, demonstrating better performance than…

This paper addresses the problem of bearing-based network localization, which aims to localize all the nodes in a static network given the locations of a subset of nodes termed anchors and inter-node bearings measured in a common reference frame. The contributions of the paper are twofold. Firstly, we propose necessary…

Cell motility requires strict spatiotemporal control of protein expression. During cell migration, mRNA localization and local translation in subcellular areas like the leading edge and protrusions are particularly advantageous for regulating the reorganization of the cytoskeleton. Fidgetin-Like 2 (FL2), a microtubule…

Giant unilamellar vesicles (GUVs) are widely used minimal cell models where essential biological features can be reproduced, isolated and studied. Although precise spatio-temporal distribution of membrane domains is a process of crucial importance in living cells, it is still highly challenging to generate anisotropic…

Emulsifiers play an essential role in ensuring the physiochemical stability of food emulsions. In the case of mayonnaise, proteins contained in egg yolk act as emulsifiers. Here, we employed stochastic optical reconstruction microscopy (STORM) to localize proteins at the oil/water droplet interface using fluorescently…

In multinuclear and multicellular filamentous fungi little is known about how mRNAs encoding secreted enzymes are transcribed and localized spatiotemporally. To better understand this process we visualized mRNA encoding GlaA, a glucoamylase secreted in large amounts by the industrial filamentous fungus Aspergillus…

Molecular photoswitches are a promising class of molecules for development of new functional, light-controlled materials. In complex systems, composed of multiple photoswitchable units, photophysical and photochemical properties may be altered as compared to isolated chromophores. And phenomena such as excitation…

The auditory system relies on binaural differences and spectral pinna cues to localize sounds in azimuth and elevation. However, the acoustic input can be unreliable, due to uncertainty about the environment, and neural noise. A possible strategy to reduce sound-location uncertainty is to integrate the sensory…

Messenger RNAs (mRNAs) accumulate at centrosomes in mitosis and interphase, yet the mechanisms governing their localization and the functional significance of centrosomal localization remain poorly understood. Here, we investigate the regulation and function of the centrosome-localized mRNA, CEP350. We find that CEP350…

Local translation at specific subcellular regions is proposed to define appropriate protein destinations and functions. However, our understanding of local translation is still far from complete, due to a lack of versatile analysis tools. Here, we developed a new method, termed “APEX-Ribo-Seq”, that integrates ribosome…

During neural development, growth cones, very motile compartments of tips of axons, lead axonal extension to the correct targets. Subsequently, presynapses, another axonal compartment with vigorous trafficking of synaptic vesicles, emerge to form functional synapses with postsynapses. In response to extracellular…

Vibrational exciton models are widely used for the simulation of biomolecular vibrational spectra, in particular of two-dimensional infrared (2D-IR) spectra. The parameters entering such models, specifically harmonic local-mode frequencies and harmonic coupling constants, are provided by vibrational maps, which have…

Protein synthesis on the endoplasmic reticulum (ER) requires the dynamic coordination of resident membrane proteins and cytoplasmic translation factors. While ER membrane proteins functioning in ribosome association, mRNA anchoring, and protein translocation, have been identified, little is known regarding the higher…

'Emilio Hernández-Garcı́a'] We study the conditions under which species interaction, as described by continuous versions of the competitive Lotka-Volterra model (namely the nonlocal Kolmogorov-Fisher model, and its differential approximation), can support the existence of localized states, i.e. patches of species with…

We present in this contribution the first application of local correlation in the context of multicomponent methods. Multicomponent approaches allow for the targeted simulation of electrons together with other fermions (most commonly protons) as quantum particles. These methods have become increasingly popular over the…
