Design and Implementation on FPGA Board of a Chaos-based Stream Cipher (2020)

Chaos based stream cipher (CSC) has caught the attention of various security applications, especially for military needs and protection in Internet of Things (IoT). In fact, computing and memory resources have been suited by chaos based stream cipher for real-time communication. In this paper, we designed a chaos-based stream cipher using a robust pseudo chaotic number generator (RPCNG). The simulation of the proposed CSC is done in VHDL using the ISE Design Suite 14.6 tool of Xilinx with finite computing precision N = 32-bit and the hardware implementation is realized on the SAKURA-G FPGA board. The proposed system requires 6036 slices L UTs as hardware cost, and achieves throughput of 301.184 Mbps. It is robust against statistical attacks and thus can be used in all applications that require confidentiality.
Simulation of transient behavior in a pulse-line-driven gyrotron oscillator (1988)

Results are reported for a set of slow-time-scale single-moded and fast-time-scale single-mode and multimode simulations of the transient-mode excitation phenomena in a short-pulse high-peak-power Ka-band gyrotron oscillator experiment. Both the slow- and fast-time-scale single-mode simulations are generally in good agreement with each other, and, within experimental uncertainties, with the experimental observations of the time dependence and magnetic-field dependence of 35-GHz emission in the TE/sub 62/ mode. However, the multimode simulations suggest the presence of mode suppression, mode beating, and other nonlinear multimode phenomena that could not easily by observed in the experiment, and generally agree less well with the experimental measurements than the single-mode simulations. The multimode simulations also suggest that steady-state behavior may not be obtainable with the highly time-dependent voltage waveform employed in the experiment, and indicate the importance of carrying out future high-voltage gyrotron experiments with less highly transient voltage waveforms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
P1–324: Altered connectome mapping in people with mild cognitive impairment and older adults with cognitive complaints (2013)

There is increasing evidence showing that cognitive decline is associated with aberrant topological organization of the brain network in AD (Lo 2010); however, the alteration of large-scale brain networks in the preclinical stages of AD remains largely unknown. Our previous studies have suggested the feasibility of earlier detection in euthymic older adults with marked cognitive complaints (CC) but normal neuropsychological test performance (Saykin 2006, Wang 2012). This study was aimed to evaluate connectome patterns in CC, mild cognitive impairment (MCI) or healthy controls (HC) based on diffusion tensor imaging (DTI). DTI was conducted in 69 participants (19 HC, 22 CC and 28 MCI) at 3T (Siemens Trio) using the following protocol: 48 non-collinear diffusion directions with b=1000 s/mm 2, echo time/repetition time=77/8300ms; 68 slices, 2x2x2 voxel size; plus 8 images with b=0s/mm 2. T1-weighted MPRAGE was acquired using the ADNI protocol. Anatomical images for each subject were segmented into different cortical regions using FreeSurfer 5.1, then parcellated into 463 regions of interest (ROIs) using the Connectome Mapping Toolkit (Cammoun 2012). Whole brain white matter (WM) fiber tracking was generated using the Diffusion Toolkit (Wang 2007). Weighted WM networks were constructed with fiber tracking between each corresponding pair of ROIs (Cheng 2012). Graph theory analysis was applied to compute connectome indices based on network metrics using the BCT package (Rubinov 2010). Using age and sex as covariates, significant differences were found for the values of degree, strength and nodal efficiency (HC > CC > MCI, p<0.05), as well as shortest path length (HC < CC < MCI, p<0.05) in precuneus, orbitofrontal and middle frontal regions. Moreover, the CC group demonstrated significantly higher nodal efficiency than the HC and MCI groups in the parahippocampal region. Early structural network degeneration was revealed with graph theoretic methods in participants at-risk for AD. The findings are largely consistent with previous reports of the connectome in AD (Lo 2010) or individuals at-risk for AD (Brown 2011). Our results suggest alterations in the specific sub-networks may indicate interconnection changes for local brain regions in prodromal AD. Regionally increased parahippocampal nodal efficiency may imply a compensatory mechanism.
<b>DISPLAY</b>: displays an eclipse in graphical form (1990)

The eclipse pictures printed in Figure 7, which show lunar and solar eclipses at various stages, were produced by subroutine DISPLAY listed later in this section. Unfortunately, it is not possible to write code which will work equally well on every computer since the mechanics of producing graphics displays varies so much from machine to machine. You will certainly have to modify DISPLAY to suit the particular characteristics of your own computer. To help you do so, I have collected all the graphics commands into a number of function calls; for example, FNCLGS clears the graphics screen to black. You can use DISPLAY just as it is provided you can define the functions so that they work on your machine. Alternatively, you may replace the functions with calls to procedures or subroutines to do the same thing. Thus, if your BASIC includes the graphics command ‘HOME’, for example, which clears the screen, you could substitute ‘GOSUB 9000’ for ‘X = FNCLGS’ and include the extra subroutine

Integrated Low‐Dimensional Semiconductors for Scalable Low‐power CMOS Logic (2023)

Abstract Scalable nanoelectronics with energy‐efficient logic technology is crucial for next‐generation edge devices. Low‐dimensional semiconductors, such as transition metal dichalcogenides and single‐walled carbon nanotubes (SWCNTs), have tunable properties with reduced short‐channel effects. The unique properties of each material can be utilized owing to the heterogeneous integration of multiple semiconducting channels to form complementary metal‐oxide‐semiconductor (CMOS) logic. However, the integration remains challenging. This study reveals the realization of low static power hetero‐CMOS inverters by the integration of n‐type monolayer MoS 2 and p‐type SWCNT networks. The balanced inverter exhibits a large peak gain of ≈67 at a supply voltage of 2 V with the customized design of the wafer‐scale synthetic process and channel integration. An ultralow standby power consumption of ≈5 pW and a practical peak gain of ≈7 at a reduced supply voltage of 0.25 V are achieved. A high noise margin (&gt;70%) validates the circuit's tolerance to external noises and the dynamic analysis of the inverting amplifier in push–pull configuration exhibits a large AC gain. This work paves the way toward the wafer‐scale integration of low‐dimensional materials for low‐power nanoelectronics.
Live, Rich, and Composable: Qualities for Programming Beyond Static Text (2023)

Efforts to push programming beyond static textual code have sought to imbue programming with multiple distinct qualities. One long-acknowledged quality is liveness: providing programmers with in-depth feedback about a program's dynamic behavior as the program is edited. A second quality, long-explored but lacking a shared term of art, is richness: allowing programmers to edit programs though domain-specific representations and interactions rather than solely through text. In this paper, we map the relationship between these two qualities and survey past work that exemplifies them. We observe that systems combining liveness and richness often do so at the cost of an essential quality of traditional programming: composability. We argue that, by combining liveness, richness, and composability, programming systems can better capture the full potential of interactive computation without leaving behind the expressivity of traditional code.
Prediction of a Supersonic Wing Flutter Boundary Using a High Fidelity Detached Eddy Simulation (2012)

Delayed Detached Eddy Simulation of supersonic flutter of a 3D wing is conducted at free stream Mach number of 1.141 using a fully coupled fluid/structure interaction (FSI). Unsteady 3D compressible Navier-Stokes equations are solved with a system of 5 decoupled structure modal equations in a fully coupled manner. The low diffusion E-CUSP scheme with a 5th order WENO reconstruction for the inviscid flux and a set of 4th order central differencing for the viscous terms are used to accurately capture the shock wave/turbulent boundary layer interaction of the vibrating wing. The predicted flutter boundary at supersonic Mach number achieves excellent agreement with experiment. It appears to be the first time that a numerical prediction of supersonic flutter boundary matches with experiment accurately.
Synthesis, NMR and Conformational Studies of Fucoidan Fragments. V.[1] Linear 4,4′,4″‐Tri‐<i>O</i>‐Sulfated and Parent Non‐sulfated (1→3)‐Fucotrioside Fragments (2003)

Abstract Propyl 4,4′,4″‐tri‐O‐sulfated and non‐sulfated (1→3)‐α‐l‐fucotriosides which are related to fragments of natural fucoidans have been synthesized. Their spectral and conformational properties have been investigated by 1H and 13C NMR, NOE and molecular modeling. Molecular mechanics calculations of the tri‐O‐sulfated compound as a trianion did not give agreement with the experimental NOE values, while the model with the non‐dissociated sulfo group on the non‐reducing end worked successfully. (1→3)‐Fucobioside fragments in both trisaccharides investigated were shown to have the same range of conformations as in previously described propyl (1→3)‐α‐l‐fucobiosides, but with the increase of the relative population of the conformer with the spatial proximity of H‐1′ and H‐4 in the case of non‐sulfated fucotrioside.

Template-assisted synthesis of III-nitride and metal-oxide nano-heterostructures using low-temperature atomic layer deposition for energy, sensing, and catalysis applications (Presentation Recording) (2015)

Recent experimental research efforts on developing functional nanostructured III-nitride and metal-oxide materials via low-temperature atomic layer deposition (ALD) will be reviewed. Ultimate conformality, a unique propoerty of ALD process, is utilized to fabricate core-shell and hollow tubular nanostructures on various nano-templates including electrospun nanofibrous polymers, self-assembled peptide nanofibers, metallic nanowires, and multi-wall carbon nanotubes (MWCNTs). III-nitride and metal-oxide coatings were deposited on these nano-templates via thermal and plasma-enhanced ALD processes with thickness values ranging from a few mono-layers to 40 nm. Metal-oxide materials studied include ZnO, TiO2, HfO2, ZrO2, and Al2O3. Standard ALD growth recipes were modified so that precursor molecules have enough time to diffuse and penetrate within the layers/pores of the nano-template material. As a result, uniform and conformal coatings on high-surface area nano-templates were demonstrated. Substrate temperatures were kept below 200C and within the self-limiting ALD window, so that temperature-sensitive template materials preserved their integrity III-nitride coatings were applied to similar nano-templates via plasma-enhanced ALD (PEALD) technique. AlN, GaN, and InN thin-film coating recipes were optimized to achieve self-limiting growth with deposition temperatures as low as 100C. BN growth took place only for &gt;350C, in which precursor decomposition occured and therefore growth proceeded in CVD regime. III-nitride core-shell and hollow tubular single and multi-layered nanostructures were fabricated. The resulting metal-oxide and III-nitride core-shell and hollow nano-tubular structures were used for photocatalysis, dye sensitized solar cell (DSSC), energy storage and chemical sensing applications. Significantly enhanced catalysis, solar efficiency, charge capacity and sensitivity performance are reported. Moreover, core-shell metal-oxide and III-nitride materials showed promise to be used in applications where flexibility is critical like functional membranes, textile and flexible electronic applications.

Vibrational dynamics in lead halide hybrid perovskites investigated by Raman spectroscopy (2020)

Lead halide perovskite semiconductors providing record efficiencies of solar cells have usually mixed compositions doped in A- and X-sites to enhance the phase stability. The cubic form of formamidinium (FA) lead iodide reveals excellent opto-electronic properties but transforms at room temperature (RT) into a hexagonal structure which does not effectively absorb visible light. This metastable form and the mechanism of its stabilization by Cs+ and Br- incorporation are poorly characterized and insufficiently understood. We report here the vibrational properties of cubic FAPbI3 investigated by DFT calculations on phonon frequencies and intensities, and micro-Raman spectroscopy. The effects of Cs+ and Br- partial substitution are discussed. We support our results with the study of FAPbBr3 which expands the identification of vibrational modes to the previously unpublished low frequency region (<500 cm-1). Our results show that the incorporation of Cs+ and Br- leads to the coupling of the displacement of the A-site components and weakens the bonds between FA+ and the PbX6 octahedra. We suggest that the enhancement of α-FAPbI3 stability can be a product of the release of tensile stresses in the Pb-X bond, which is reflected in a red-shift of the low frequency region of the Raman spectrum (<200 cm-1).
Unsupervised machine learning in 5G networks for low latency communications (2017)

This paper incorporates fog networking into heterogeneous cellular networks that are composed of a high power node (HPN) and many low power nodes (LPNs). The locations of the fog nodes that are upgraded from LPNs are specified by modifying the unsupervised soft-clustering machine learning algorithm with the ultimate aim of reducing latency. The clusters are constructed accordingly so that the leader of each cluster becomes a fog node. The proposed approach significantly reduces the latency with respect to the simple, but practical, Voronoi tessellation model, however the improvement is bounded and saturates. Hence, closed-loop error control systems will be challenged in meeting the demanding latency requirement of 5G systems, so that open-loop communication may be required to meet the 1ms latency requirement of 5G networks.
Use of thermodynamic coupling between antibody–antigen binding and phospholipid acyl chain phase transition energetics to predict immunoliposome targeting affinity (2014)

Thermodynamic analysis of ligand-target binding has been a useful tool for dissecting the nature of the binding mechanism and, therefore, potentially can provide valuable information regarding the utility of targeted formulations. Based on a consistent coupling of antibody-antigen binding and gel-liquid crystal transition energetics observed for antibody-phosphatidylethanolamine (Ab-PE) conjugates, we hypothesized that the thermodynamic parameters and the affinity for antigen of the Ab-PE conjugates could be effectively predicted once the corresponding information for the unconjugated antibody is determined. This hypothesis has now been tested in nine different antibody-targeted echogenic liposome (ELIP) preparations, where antibody is conjugated to dipalmitoylphosphatidylethanolamine (DPPE) head groups through a thioether linkage. Predictions were satisfactory (affinity not significantly different from the population of values found) in five cases (55.6%), but the affinity of the unconjugated antibody was not significantly different from the population of values found in six cases (66.7%), indicating that the affinities of the conjugated antibody tended not to deviate appreciably from those of the free antibody. While knowledge of the affinities of free antibodies may be sufficient to judge their suitability as targeting agents, thermodynamic analysis may still provide valuable information regarding their usefulness for specific applications.

Wing Polymorphism and Dispersal of &lt;I&gt;Scaptocoris carvalhoi&lt;/I&gt; (Hemiptera: Cydnidae) (2008)

Functional wing polymorphism is commonly observed in insects, and it may confer an important adaptive value to populations that bear this trait, because it allows dispersal and the location to more favorable habitats for their survival and reproduction. According to the oogenesis-ight syndrome theory, such wing polymorphism may imply differences in the locomotion capacity of individuals, which is a factor induced by adverse environmental conditions during muscle development in immatures. Scaptocoris carvalhoi Becker (Hemiptera: Cydnidae) is an important agriculture pest in Brazil, and it has burrowing habits. The adults swarm in the beginning of the rainy season after a prolonged drought period in the Brazilian cerrado region. In these swarms, part of the population leaves the soil, performing long ights until locations with more abundant vegetation. In this study, we characterized wing polymorphism in S. carvalhoi, this being the rst description in a species of Cydnidae. Brachypterous and macropterous males and females were observed, which showed positive and signicant correlations between body length and hindwing length. Macropterous individuals demonstrated greater locomotion capacity than brachypterous individuals. In addition, only longwinged adults could y, showing wing mobility and ight reaction. The increased number of macropterous individuals inside the soil during the swarming season and in the beginning of the rainy period suggests that wing polymorphism in this population occurs in seasonal cycles and that factors related to the scarcity of rains inuence the development of immatures and the formation of polymorphic adults.
Effects of the Licorice Extract against Tumor Growth and Cisplatin-Induced Toxicity in a Mouse Xenograft Model of Colon Cancer (2007)

Cisplatin is one of the most effective chemotherapeutic agents and plays a major role in the treatment of a variety of human solid tumors. However, its toxicity limits the clinical use. Recently, the administration of antioxidants has been suggested to protect against cisplatin-induced nephrotoxicity. The present study was designed to estimate the antitumor activity of the licorice extract alone and in combination with cisplatin, and its protective potential against cisplatin-induced toxicity in a mouse xenograft model. The administration of the licorice extract significantly inhibited tumor growth in BALB/C mice inoculated with CT-26 colon cancer cells. The combination of the licorice extract and cisplatin diminished the therapeutic efficacy of cisplatin but promoted considerably antitumor activity of the licorice extract. In mice with cisplatin treatment for 15 d, the serum levels of blood urea nitrogen and creatinine remarkably were increased by kidney damage, and the serum alanine aminotransferase and aspartate aminotransferase levels were elevated by liver damage. The administration of the licorice extract plus cisplatin recovered these functional indices in the kidney and liver to almost the control levels. In addition, the administration of the licorice extract significantly reduced the cisplatin-induced oxidative stress. Taken together, the administration of the licorice extract inhibits the growth of mouse colon carcinoma without any adverse effects, and reduces the cisplatin-induced toxicity. Therefore, the licorice extract may be a candidate for an anticancer and chemopreventive agent. However, cancer patients with cisplatin therapy should avoid the supplementation of the licorice extract.
Monitoring and Evaluation of Blood Pressure Changes With a Home Healthcare System (2011)

We investigated changes in blood pressure with exercise, including walking and ergometer training, sleep, and body weight. Blood pressure was monitored over a period of about 1 year in 61 subjects in Osaka, Japan. The morning systolic blood pressures were analyzed using multivariate regression analysis, and the correlations between systolic blood pressure and the above parameters were determined. The systolic blood pressure distribution was classified into improved, stable, and ingravescence groups. In the improved group, exercise intensity and total calories were important factors controlling the systolic blood pressure. More than 300 kcal per day was needed to improve the systolic blood pressure. In the stable and ingravescence groups, body weight control was also an important factor in maintaining blood pressure. An increase of 1 kg in body weight was associated with systolic blood pressure increases of 3 and 6 mm Hg in the stable and ingravescence groups, respectively. The long-term repeated use of home blood pressure testing may be a good self-care strategy for monitoring daily health.
Abnormal mixing of passive scalars in chaotic flows (2007)

We study the relaxation of a passive scalar towards the uniform equilibrium distribution in an advection-diffusion problem where the phase space for the pure advection problem is a mixture of chaotic domains and elliptic islands. Since the advection-diffusion problem is linear, the relaxation can be characterized by the eigenvalues and eigenmodes of the evolution operator. Almost degenerate eigenvalues then give rise to deviations from simple exponential decay behavior. We show by example that the corresponding eigenmodes can be supported by islands or weakly connected chaotic domains. These theoretical considerations are related to some experimental observations in two-dimensional flows.
