Statistical Properties of Digital Piecewise Linear Chaotic Maps and Their Roles in Cryptography and Pseudo-Random Coding ⋆

Field: Mathematics (Physical Sciences)

Abstract. The applications of digital chaotic maps in discrete-time chaotic cryptography and pseudo-random coding are widely studied recently. However, the statistical properties of digital chaotic maps are rather different from the continuous ones, which impedes the theoretical analyses of the digital chaotic ciphers and pseudo-random coding. This paper detailedly investigates the statistical properties of a class of digital piecewise linear chaotic map (PLCM), and rigorously proves some useful results. Based on the proved results, we further discuss some notable problems in chaotic cryptography and pseudo-random coding employing digital PLCM-s. Since the analytic methods proposed in this paper can essentially extended to a large number of PLCM-s, they will be valuable for the research on the performance of such maps in chaotic cryptography and pseudo-random coding. 1

Exploiting the metabolic dependencies of the broad amino acid transporter SLC6A14

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Tumor cells typically enhance their metabolic capacity to sustain their higher rate of growth and proliferation. One way to elevate the nutrient intake into cancer cells is to increase the expression of genes encoding amino acid transporters, which may represent targetable vulnerabilities. Here, we study the regulation and function of the broad amino acid transporter SLC6A14 in combination with metabolic stress, providing insights into an uncharacterized aspect of the transporter activity. We analyze the pattern of transcriptional changes in a panel of breast cancer cell lines upon metabolic stress and found that SLC6A14 expression levels are increased in the absence of methionine. Methionine deprivation, which can be achieved via modulation of dietary methionine intake in tumor cells, in turn leads to a heightened activation of the AMP-activated kinase (AMPK) in SLC6A14-deficient cells. While SLC6A14 genetic deficiency does not have a major impact on cell proliferation, combined depletion of AMPK and SLC6A14 leads to an increase in apoptosis upon methionine starvation, suggesting that combined targeting of SLC6A14 and AMPK can be exploited as a therapeutic approach to starve tumor cells.

Correlation Analysis of Soil Physicochemical Properties and Aboveground Biomass in Leymus chinensis Grassland for Different Utilization

Field: Agricultural and Biological Sciences (Life Sciences)

The soil physicochemical properties and aboveground biomass at heavy grazing grassland, pruning grassland and enclosure grassland in Hulun Buir Leymus chinensis grassland were analyzed in this study. The results showed that the phosphorus, 10 ~20 cm water content and aboveground biomass wet weight in enclosure showed strong positive correlation with aboveground biomass dry weight. The correlation between wet weight and dry weight of aboveground biomass was extremely positive(P0.01). 0~10 cm bulk density showed a significant negative correlation with aboveground biomass(P0.05). In the pruning grassland, the phosphorus, available nitrogen, 0 ~10 cm bulk density, aboveground biomass wet weight all showed strong positive correlation with dry weight of aboveground biomass. 0~10 cm and 10~20 cm water content and 10~20 cm bulk density showed weak positive correlation with dry weight of aboveground biomass. And the organic matter and aboveground biomass dry weight were significantly negative correlation(P0.05). In heavy grazing grassland, the wet weight and dry weight of aboveground biomass showed extremely positive correlation(P0.01). The total nitrogen and 10~20 cm bulk density presented weak positive correlation with aboveground biomass dry weight. 0 ~10 cm bulk density showed a strong negative correlation with aboveground dry weight. It indicated that phosphate fertilizer and scarification should be regarded as main indicators of soil restoration to increase aboveground biomass in enclosed grassland, and nitrogen fertilizer and scarification in heavy grazing pasture, as well as phosphate fertilizer and nitrogen fertilizer in pruning grassland.

The comparative chemical morphology of the mammalian cornea.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

A simple model of mammalian corneal stroma has been tested against biochemical and ultrastructural measurements performed on a number of species. Contents of water, collagen and total sulphated polyanion were constant, as predicted from the model. Alcian blue CEC results showed great variability between species, with a rise in CEC as corneal size and thickness increased. These variations were due to changes in keratan sulphate content, and particularly to its oversulphated terminal domain, which is absent from mouse cornea. The increase in keratan sulphate content with corneal thickness was balanced by an increase in dermatan sulphate in thin corneas, thus maintaining total sulphated GAG levels at a constant "average", in all the mammals investigated. This balance is probably decided by oxygen tension, which will vary with corneal thickness.

In comparison with the recommendations of the Saudi local training committee, 53.8% of residents feel the surgical exposure is less . Residents (84.8 %) were found to be satisfied with the local training.Conclusion: These results show general satisfaction with current training. The study suggests that there are significant strong points in the current program. We feel monitoring and frequent evaluation are the warranty for improving local program.
Geographies of consumption: engaging with absent presences

Field: Social Sciences (Social Sciences)

For geographers and others studying landscapes of consumption, sustained engagements with ‘absent presences’ — be they historically constituted or exhibited as more contemporary silences — have prompted researchers to reflect on contradictions and biases in narratives, exposing taken-for-granted assumptions about the research endeavour and the subjects of research. Focusing on research related to consuming, branding imaginaries, material and relational geographies, I outline how researchers have examined existing categorizations and conceptualizations of consumption practices and places to reflect on the power and politics ‘at work’.
Understanding the Dynamics of the Structural States of Cannabinoid Receptors and the Role of Different Modulators

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The cannabinoid receptors CB1R and CB2R are members of the G protein-coupled receptor (GPCR) family. These receptors have recently come to light as possible therapeutic targets for conditions affecting the central nervous system. However, because CB1R is known to have psychoactive side effects, its potential as a drug target is constrained. Therefore, targeting CB2R has become the primary focus of recent research. Using various molecular modeling studies, we analyzed the active, inactive, and intermediate states of both CBRs in this study. We conducted in-depth research on the binding properties of various groups of cannabinoid modulators, including agonists, antagonists, and inverse agonists, with all of the different conformational states of the CBRs. The binding effects of these modulators were studied on various CB structural features, including the movement of the transmembrane helices, the volume of the binding cavity, the internal fluids, and the important GPCR properties. Then, using in vitro experiments and computational modeling, we investigated how vitamin E functions as a lipid modulator to influence THC binding. This comparative examination of modulator binding to CBRs provides significant insight into the mechanisms of structural alterations and ligand affinity, which can directly help in the rational design of selective modulators that target either CB1R or CB2R.
Mössbauer Spectroscopy of [N(CH3)4]2FeCl4

Field: Chemistry (Physical Sciences)

Mössbauer spectrum of 57 Fe of [N(CH 3 ) 4 ] 2 FeCl 4 was measured as a function of temperature in the temperature range 20∼290 K. Single doublet was observed in the orthorhombic phase (phase I). The spectrum is almost the same in the incommensurate phase (phase II) and in the phase II ′ where the structure is modulated in the z -direction with the wavenumber 3/7. These modulation seems to raise no large EFG (electric field gradient) modulation to cause noticeable change in the spectrum. A new doublet appears in the phase III where the structure is commensurate with the cell tripling along the c axis. This doublet persists even to the phase IV where the structure is monoclinic with Z =4. If we consider the crystal symmetry, the extra doublet is prohibited in this phase. The extra EFG is interpreted as the peculiarity to the powder sample.
Experimental characterization optimizing the alignment parameter for GNP epoxy base nanocomposite via a weak DC magnetic field

Field: Materials Science (Physical Sciences)

Abstract Graphene has been hailed by scientists as the “wonder material” of the 21st century. Despite the impressive mechanical and electrical qualities of graphene in its unprocessed state, graphene‐based epoxy nanocomposites can only be used as a structural material on a small scale. The random dispersion and orientation of graphene in epoxy cause the failure. Magnetite Fe 3 O 4 nanoparticles are synthesized and solvo‐thermally attached to the graphene nanoplatelets (GNP) surfaces in order to utilize our recently model's suggested optimized alignment parameters. Solution with properly dispersed nanoparticles, that is, Fe 3 O 4 ‐GNP within epoxy, is exposed to the magnetic field (0.05 T). Morphology, microstructure, and magnetic properties of GNP, Fe 3 O 4 , and Fe 3 O 4 ‐GNP nanoparticles have been characterized by X‐ray diffraction, Fourier‐transform infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, differential scanning calorimetry, atomic force microscopy, X‐ray photoelectron spectroscopy, Brunauer–Emmett–Teller, transmission electron microscopy, scanning electron microscopy, energy‐dispersive X‐ray microanalysis, and vibrating sample magnetometry. The aforementioned characterization method, optical microscopy, and studying the fracture surface morphology confirmed the alignment. The fabricated aligned Fe 3 O 4 ‐GNP nanocomposite is best used as a functional material.

Group size and dispersal ploys: an analysis of commuting behaviour of the pond bat (Myotis dasycneme)

Field: Agricultural and Biological Sciences (Life Sciences)

Like most bat species, the pond bat (Myotis dasycneme (Boie, 1825)) lives in roosts more or less in the centre of their foraging habitat and are considered central-place foragers. Commuting routes, or flyways, between roosts and hunting areas have an essential ecological function for bats. We summarize the results of research performed on the commuting routes of pond bats between 2002 and 2009. We give, among others, a description on how bats disperse, how to recognize a commuting route, and details about the effort needed to make a complete survey of one commuting route. Furthermore, we make a relation between number of animals on the route and size of their respective roost. The results suggest pond bats are not completely reliant on waterways for reaching their foraging habitat; they use directional dispersal, following commuting routes over waterways in combination with shortcuts over land. These results provide information that can be used to better understand how bats use their commuting routes. Also, the knowledge can be applied to survey work.

Hierarchical Micro-/Nanotopographies Patterned by Tandem Nanosphere Lens Lithography and UV–LED Photolithography for Modulating PC12 Neuronal Differentiation

Field: Materials Science (Physical Sciences)

Modulating neuronal behavior via topographical cues is integral to studying neuronal development, building in vitro neural networks, and designing better neural interfaces and nerve regeneration devices. While numerous topographies with micro- and nanoscale features have been investigated, studies involving hierarchically patterned substrates containing both micro- and nanoscale structures have been limited, which may be due, in part, to the technical challenges involved in their fabrication. In this work, we utilize for the first time a facile, low-cost fabrication method using nanosphere lens lithography and UV–LED photolithography for creating ordered, hierarchical structures consisting of nanodots or nanopillars on microgrooves using the photosensitive polymer SU-8. Pheochromocytoma 12 (PC12) cells are differentiated on the micro-/nanopatterned films in the presence of nerve growth factor, and their neurite outgrowth and orientation are characterized by semi-automatic analysis of fluorescence images. The results show that nanopillars with micron-scale gaps significantly inhibited neurite outgrowth and branching. When combined with microgrooves, the nanopillar array resulted in more neurites and cell somas being localized on the ridges in the hierarchical substrates, which was associated with significantly improved neurite alignment on the ridges compared with the plain microgroove substrate. Visualization of filopodia-like projections and adhesion formation reveal the entrapment of thin projections and the inhibition of cell–matrix interactions on the nanopillar array, which could be responsible for the modulation of neurite development. The hierarchically patterned photosensitive substrates, fabricated using our proposed simple and cost-effective method, can thus be utilized in controlling the neurite outgrowth and alignment of neuronal cells for applications ranging from basic neuroscience to nerve regeneration.
New insight into the performance analysis of flow-electrode capacitive deionization by varying the operation voltage

Field: Environmental Science (Physical Sciences)

In the flow-electrode capacitive deionization (FCDI), the highly activated porous carbon electrodes of slurry phase flows through the channels of current collectors and adsorbs the salt ions when a voltage is applied. In this study, the effect of voltage on the performance of a FCDI cell is experimentally investigated. The voltage is applied on the top corner of a FCDI cell (Vapply) and simultaneously the voltage of central cell (Vcell) is measured. The experiments were conducted by applying voltages from 0.6 to 3.9 V. The experimental results show that the difference between Vapply and Vcell is a function of salt concentrations of the feed water. The higher voltages (Vapply>1.2V) can be used for increasing the salt removal efficiency (E) for higher salt water concentrations without electrolysis. Also, the results show that E increases along with the applied voltage. A series of pH measurements were done in regard to investigation of electrolysis point of the setup.
Bioaffinity Fishing Procedure Using Secretory Phospholipase A2 for Screening for Bioactive Components: Modulation of Pharmacological Effect Induced by sPLA2 from Crotalus durissus terrificus by Hispidulin from Moquiniastrum floribundum

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Bioaffinity capturing of molecules allows the discovery of bioactive compounds and decreases the need for various stages in the natural compound isolation process. Despite the high selectivity of this technique, the screening and identification methodology depends on the presence of a protein to capture potential ligands. However, some proteins, such as snake secretory phospholipase A2 (sPLA2), have never been investigated using this approach. The purpose of this study was to evaluate the use of a new method for screening natural compounds using a bioaffinity-guided ultrafiltration method on Crotalus durissus terrificus sPLA2 followed by HPLC-MS to identify the compounds, and this method could be used to discover new anti-inflammatory compounds from the various organisms originating from biodiversity. Different extracts were selected to evaluate their ability to inhibit sPLA2 activity. The extracts were incubated with sPLA2 and the resulting mixture was ultrafiltrated to elute unbound components. The resulting compounds were identified by HPLC-MS. We identified hispidulin as one of the components present in the Moquiniastrum floribundum leaf and evaluated the ability of this isolated compound to neutralize the inflammatory activity of sPLA2 from Crotalus durissus terrificus.
