AbstractThis paper is a case study in the exploration of the semantic range of single a high-frequency lexical item on the basis of a corpus of spoken language, in this case Moroccan Arabic. Generalised action verbs (‘do’ verbs) are an interesting object of study because cross-linguistically, they can exhibit a wide range of functions including that of causative verb, verb of creation, verb in agentive collocations, verbaliser with loan words and mimetic expressions, quotative verb, and even a copula-like use with property predicates (Schultze-Berndt 2008). Against this typological background, the range of functions of Moroccan Arabic

Range Of Functions

SlipChips are two-part microfluidic devices that can be reconfigured to change fluidic pathways for a wide range of functions, including tissue stimulation. Currently, fabrication of these devices at the prototype stage requires a skilled microfluidic technician, e.g., for wet etching or alignment steps. In most cases, SlipChip functionality requires an optically clear, smooth, and flat surface that is fluorophilic and hydrophobic. Here, we tested digital light processing (DLP) 3D printing, which is rapid, reproducible, and easily shared, as a solution for fabrication of SlipChips at the prototype stage. As a case study, we sought to fabricate a SlipChip intended for local delivery to live tissue slices through a movable microfluidic port. The device was comprised of two multi-layer components: an enclosed channel with a delivery port and a culture chamber for tissue slices with a permeable support. Once the design was optimized, we demonstrated its function by locally delivering a chemical probe to slices of hydrogel and to living tissue with up to 120 µm spatial resolution. By establishing the design principles for 3D printing of SlipChip devices, this work will enhance the ability to rapidly prototype such devices at mid-scale levels of production.

Focusing on the reader’s benefit: Digital reading media offer a wide range of functions compared to print media: search functions, bookmarking, annotations, social reading, etc. However, they often fail to meet basic usability requirements, hindering reception and driving readers back to print media. This dissertation designs a reference model and derives a set of suitable methods from it with which to measure and improve the usability of digital reading media, including heuristic evaluation, user observation and eye-tracking, which it empirically tests on professional journal apps in a multiple case study. Sibylle Kunz is a professor of media computer science at IUBH International University, conducting research on digital reading media and their usability.

Long noncoding RNAs (lncRNAs) have a wide range of functions in health and disease, but many remain uncharacterized because of their complex expression patterns and structures. The genetic loci encoding lncRNAs can be subject to accelerated evolutionary changes within the human lineage. HAR1 is a region that has a significantly altered sequence compared to other primates and is a component of two overlapping lncRNA loci, HAR1A and HAR1B. Although the functions of these lncRNAs are unknown, they have been associated with neurological disorders and cancer. Here, we explore the current state of understanding of evolution in human lncRNA genes, using the HAR1 locus as the case study.

Although RNA viruses exhibit a high frequency of host jumps, major differences exist among the different virus families. Astroviruses infect a wide range of hosts, affecting both public health systems and economic production chains. Here we delineate the ecological and adaptive processes that drive the cross-species transmission of astroviruses. We observe that distinct transmission zones determine the prevailing astrovirus host and virus diversity, which in turn suggests that no single host group (e.g., bats) can be the natural reservoir, as illustrated through our phylogenetic analysis.

Several studies have shown that the success of interregional cooperation may be influenced by coordination, commitment, participation, variance of cooperation, structure, format of cooperation, and political will. Nevertheless, these factors do not stand alone since actor relations as a determining aspect is capable of driving those factors effectively. This article aims to examine the aspect of actor relations as a contributing factor that determines successful cooperation among regions. This is a qualitative research with the policy of inter-regional cooperation of the Banjarbakula Program, South Kalimantan Province from February 2017 to February 2018, set as its object of study. The result of this study states that the success of inter-regional cooperation is influenced by the relationship of actors in development factors as suggested by previous experts. The actors involved in the inter-regional cooperation examined in this case had become triggers of coordination, commitment, and participation toward success and failure, as well as the effectiveness of regional cooperation policy. Structural obstacles, ego-centric character, minimum budget availability, and non-visionary planning could be overcome as long as actor relations were properly managed.

<p>The Soil Science Institute of Thessaloniki produces new digitized Soil Maps that provide a useful electronic database for the spatial representation of the soil variation within a region, based on in situ soil sampling, laboratory analyses, GIS techniques and plant nutrition mathematical models, coupled with the local land cadastre. The novelty of these studies is that local agronomists have immediate access to a wide range of soil information by clicking on a field parcel shown in this digital interface and, therefore, can suggest an appropriate treatment (e.g. liming, manure incorporation, desalination, application of proper type and quantity of fertilizer) depending on the field conditions and cultivated crops. A specific case study is presented in the current work with regards to the construction of the digitized Soil Map of the regional unit of Kastoria. The potential of this map can easily be realized by the fact that the mapping of the physicochemical properties of the soils in this region provided delineation zones for differential fertilization management. An experiment was also conducted using remote sensing techniques for the enhancement of the fertilization advisory software database, which is a component of the digitized map, and the optimization of nitrogen management in agricultural areas.</p>

Background & Objective: Neurodegenrative diseases are among the most widespread lifethreatening disorders around the world in elderly ages. The common feature of a group of neurodegenerative disorders, called tauopathies, is an accumulation of microtubule associated protein tau inside the neurons. The exact mechanism underlying tauopathies is not well-understood but several factors such as traumatic brain injuries and genetics are considered as potential risk factors. Although tau protein is well-known for its key role in stabilizing and organization of axonal microtubule network, it bears a broad range of functions including DNA protection and participation in signaling pathways. Moreover, the flexible unfolded structure of tau facilitates modification of tau by a wide range of intracellular enzymes which in turn broadens tau function and interaction spectrum. The distinctive properties of tau protein concomitant with the crucial role of tau interaction partners in the progression of neurodegeneration suggest tau and its binding partners as potential drug targets for the treatment of neurodegenerative diseases. Conclusion: This review aims to give a detailed description of structure, functions and interactions of tau protein in order to provide insight into potential therapeutic targets for treatment of tauopathies.

The traditional way to mitigate loss circulation in drilling operations is to use preventative and curative materials. However, it is difficult to quantify the amount of materials from every possible combination to produce customized rheological properties. In this study, machine learning (ML) is used to develop a framework to identify material composition for loss circulation applications based on the desired rheological characteristics. The relation between the rheological properties and the mud components for polyacrylamide/polyethyleneimine (PAM/PEI)-based mud is assessed experimentally. Four different ML algorithms were implemented to model the rheological data for various mud components at different concentrations and testing conditions. These four algorithms include (a) k-Nearest Neighbor, (b) Random Forest, (c) Gradient Boosting, and (d) AdaBoosting. The Gradient Boosting model showed the highest accuracy (91 and 74% for plastic and apparent viscosity, respectively), which can be further used for hydraulic calculations. Overall, the experimental study presented in this paper, together with the proposed ML-based framework, adds valuable information to the design of PAM/PEI-based mud. The ML models allowed a wide range of rheology assessments for various drilling fluid formulations with a mean accuracy of up to 91%. The case study has shown that with the appropriate combination of materials, reasonable rheological properties could be achieved to prevent loss circulation by managing the equivalent circulating density (ECD).
