Tunable bandpass frequency selective surface with embedded biasing (2016)

This article presents a tunable bandpass frequency selective surface (FSS) based on varactor diodes. The FSS is made of three metallic layers that are separated from each other by two thin dielectric spacers. Tunability is achieved by loading varactor diodes on the front and back layers. The varactors are connected to the middle layer wire grid and are tuned by applying a bias voltage between the middle and front/back layers wire grids. The proposed tuning concept is validated by fabricating an FSS prototype and testing it in a parallel plate waveguide setup.
The host range restriction of bat-associated no-known-vector flaviviruses occurs post-entry (2021)

Most flaviviruses are transmitted horizontally between vertebrate hosts by haematophagous arthropods. Others exhibit host ranges restricted to vertebrates or arthropods. Vertebrate-specific flaviviruses are commonly referred to as no-known-vector (NKV) flaviviruses and can be separated into bat- and rodent-associated NKV flaviviruses. Rio Bravo virus (RBV) is one of eight recognized bat-associated NKV (B-NKV) flaviviruses. Studies designed to identify the genetic determinants that condition the host range restriction of B-NKV flaviviruses have never been performed. To investigate whether the host range restriction occurs at the level of attachment or entry, chimeric flaviviruses were created by inserting the pre-membrane and envelope protein genes of RBV into the genetic backbones of yellow fever virus (YFV) and Zika virus (ZIKV), two mosquito-borne flaviviruses associated with human disease. The chimeric viruses infected both vertebrate and mosquito cells. In vertebrate cells, all viruses produced similar mean peak titres, but the chimeric viruses grew more slowly than their parental viruses during early infection. In mosquito cells, the chimeric virus of YFV and RBV grew more slowly than YFV at early post-inoculation time points, but reached a similar mean peak titre. In contrast, the chimeric virus of ZIKV and RBV produced a mean peak titre that was approximately 10-fold lower than ZIKV. The chimeric virus of YFV and RBV produced an intermediate plaque phenotype, while the chimeric virus of ZIKV and RBV produced smaller plaques than both parental viruses. To conclude, we provide evidence that the structural glycoproteins of RBV permit entry into both mosquito and vertebrate cells, indicating that the host range restriction of B-NKV flaviviruses is mediated by a post-attachment/entry event.
A Fast Algorithm for APES and Capon Spectral Estimation (2008)

In this paper, we derive a novel implementation of some very computationally demanding matched filter-bank-based spectral estimators, namely the amplitude and phase estimator (APES), the amplitude spectrum Capon (ASC) estimator, and the power spectrum Capon (PSC) estimator. Filter-bank-based spectral estimation methods that adopt data-dependent filter banks can provide spectra characterized by a significantly improved resolution compared to classical approaches. However, the computational complexity of the currently available implementation algorithms, is extremely high. A novel technique is introduced that provides efficient algorithms for the computation of the APES, ASC, and PSC spectra. The proposed method is based on suitable displacement representations of all pertinent data matrices, that are subsequently utilized for the computation of the associated complex valued polynomials. The computational complexity of the proposed algorithms is lower than all relevant existing methods.
Dihydroergotamine (1987)

Dihydroergotamine (DHE) elicits selective and long-lasting venoconstrictor activity, although the drug disappears rapidly from the blood. Therefore, a comparative study on the pharmacokinetic and pharmacodynamic properties of DHE was performed in beagle dogs. In addition, the mechanism of the venoconstrictor activity of DHE was investigated in vivo. Changes in the diameter of the saphenous vein and plasma level-time curves of DHE and its metabolites were determined in conscious beagle dogs. After both intravenous and oral administrations of DHE, the venoconstrictor response is of markedly longer duration than would be expected on the basis of the half-life for elimination of DHE from blood. The experimental data support the suggestion that the long duration of the DHE-induced venoconstriction is due to an extremely slow dissociation of the drug from its receptor sites on the venous smooth muscle cell, and to the formation of active metabolites. Using the antagonists ketanserin, pizotifen, and rauwolscine, evidence is presented that the venoconstrictor activity of DHE is mediated through stimulation of 5-HT receptors; there is no evidence of involvement of alpha-adrenoceptors.
Traffic-aware channel width adaptation in long-distance 802.11 mesh networks (2012)

We consider the traffic adaptive channel allocation problem in long-distance 802.11 mesh networks. Our approach is to exploit the capability provided by 802.11 hardware to use different channel widths and assign channel widths to links based on their relative traffic volume. We show that this traffic-aware channel width assignment problem is NP-complete and propose a polynomial time, greedy channel allocation algorithm that guarantees valid channel allocations for each node. Evaluation of the proposed algorithm via simulations of real network topologies shows that it consistently outperforms the current approach of fixed width allocation due to its ability to adapt to spatio-temporal variations in traffic demands.
Distillation Curves for Alcohol−Gasoline Blends (2010)

Distillation curves are presented for single-alcohol blends in gasoline, containing 5−85% by volume of methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, i-butanol (2-methyl-1-propanol), and t-butanol (2-methyl-2-propanol). Most alcohols are shown to form mixtures with gasoline exhibiting near-azeotropic behavior that significantly affect the shape of the distillation curves. The results are compared to literature data available for some alcohols. In addition, distillation curves for a variety of dual-alcohol blends are presented, containing 10% of each of two alcohols. We show that such dual-alcohol blends have distillation curves closer to that of the base gasoline than single-alcohol blends with 20% of either alcohol individually. At present, ethanol is the only biofuel alcohol available in scale. As other alcohol biofuels become available in the future, it may be advantageous to use them in dual- or multialcohol blends to minimize their impact on fuel volatility.
The Age of Elite Swimmers Decreases as Freestyle Event Distance Increases (2016)

Allen, Vandenbogaerde, and Hopkins (2014) reported that age at peak swim performance for elite-level swimmers decreased as event distance increased in the freestyle events. They suggested that their findings might result from distance swimmers dropping out of the sport prematurely or switching to shorter events. If they are correct, then the elite distance swim population should be younger than the corresponding populations for sprinters and mid-distance swimmers. PURPOSE: To determine whether or not the age of the elite American swim population varies with freestyle event distance. METHODS: The mean age of all competitors (ALL ENTRANTS) and the top-8 finishers (FINALISTS) in the 50-m and 100-m freestyle (SPR), 200-m and 400-m freestyle (MD), and 800-m and 1500-m freestyle (DIST) events was determined for United States Long Course National Swim Championships from 1982 to 2012. Three-way ANOVA was used to determine if event distance affected ALL ENTRANTS and FINALISTS, and if event distance interacted with the sex of the athletes or the year in which the meet occurred. Tukey’s HSD was used to make pairwise comparisons when significant main effects were detected. RESULTS: ALL ENTRANTS was significantly older for SPR (20.27 years, SD 1.05) than for MD (19.31 years, SD 0.87), which was significantly older than DIST (18.50 years, SD 0.88). Similarly, FINALISTS was significantly older for SPR (21.89 years, SD 1.71) than for MD (20.04 years, SD 1.40), which was significantly older than for DIST (18.85 years, SD 1.30). ALL ENTRANTS and FINALISTS were both significantly greater for men than for women, and both significantly increased across the time period in question, but neither factor interacted with event distance. CONCLUSIONS: While these findings agree with the suggestion posed by Allen et al., it remains unclear as to why elite distance swimmers are younger than mid-distance swimmers, who are in turn younger than sprinters. Research is needed on the reasons elite athletes choose to end their careers in order to better understand this relationship.
Increasing Flash Memory Lifetime by Dynamic Voltage Allocation for Constant Mutual Information (2014)

The read channel in Flash memory systems degrades over time because the Fowler-Nordheim tunneling used to apply charge to the floating gate eventually compromises the integrity of the cell because of tunnel oxide degradation. While degradation is commonly measured in the number of program/erase cycles experienced by a cell, the degradation is proportional to the number of electrons forced into the floating gate and later released by the erasing process. By managing the amount of charge written to the floating gate to maintain a constant read-channel mutual information, Flash lifetime can be extended. This paper proposes an overall system approach based on information theory to extend the lifetime of a flash memory device. Using the instantaneous storage capacity of a noisy flash memory channel, our approach allocates the read voltage of flash cell dynamically as it wears out gradually over time. A practical estimation of the instantaneous capacity is also proposed based on soft information via multiple reads of the memory cells.
Multicarrier pulse width modulation methods based three phase cascaded multilevel inverter including over modulation and low modulation indices (2009)

The multilevel inverter utilization have been increased since the last decade. These new type of inverters are suitable in various high voltage & high power application due to their ability to synthesize waveforms with better harmonic spectrum and faithful output. This paper presents, two proposed scheme adopting the multicarrier pulse width modulation concept. The multicarrier pulse width modulation cascaded multilevel inverter strategy enhances the fundamental output voltage and reduced total harmonic distortion. The multilevel inverter circuit analysis and selection of proper references discussed based on the formulation switching patterns. A three phase five level cascaded inverter is used to explain the methods. The methods can be easily extended to a n-level inverter. The cascaded inverter is subjected to a new modulation scheme, which uses multiple modulating signals with a single carrier. From the modulation scheme, mathematical equations that define the pulse width modulation switching instants are derived. In order to justify the merits of the proposed modulation scheme, harmonic analysis for and measured total harmonic distortion and output voltages are compared and discussed. The method can be confirmed by experimental results obtained using a three phase cascaded five level inverter.

Electrostatic Twisting of Core–Shell Nanofibers for Strain Sensing Applications (2020)

Stretchable strain sensors are increasingly needed in emerging fields of wearable electronics and smart textiles for applications ranging from human motion detection to health monitoring. Nanofibers made from conductive materials or composites of polymers and conductive nanoparticles exhibit strong sensitivities but are difficult to be utilized because of their small dimensions. In the present article we report on a technique for producing core–shell nanofibers and their in situ twisting using a rotating electric field. The process produces sensitive threads that can be handled easily and used, for instance, in smart textile applications. The core–shell nanofibers utilized poly(vinylidene fluoride) as the structural polymer, and multiwalled carbon nanotubes were used to make the core electrically conductive. The structure of nanofibers was studied through a set of analytical methods. The fibers exhibit strong piezoresistive responses and can be utilized in various strain sensing applications. The mechanical properties of fabricated submicron fiber yarns are compared with nontwisted fibers, and improvement of their stretchability has been demonstrated. Furthermore, the sensitivity of fiber threads to different directions of stretching depending on the way of their knitting into fabric has been compared.
Imagine All the People: How the Brain Creates and Uses Personality Models to Predict Behavior (2013)

The behaviors of other people are often central to envisioning the future. The ability to accurately predict the thoughts and actions of others is essential for successful social interactions, with far-reaching consequences. Despite its importance, little is known about how the brain represents people in order to predict behavior. In this functional magnetic resonance imaging study, participants learned the unique personality of 4 protagonists and imagined how each would behave in different scenarios. The protagonists' personalities were composed of 2 traits: Agreeableness and Extraversion. Which protagonist was being imagined was accurately inferred based solely on activity patterns in the medial prefrontal cortex using multivariate pattern classification, providing novel evidence that brain activity can reveal whom someone is thinking about. Lateral temporal and posterior cingulate cortex discriminated between different degrees of agreeableness and extraversion, respectively. Functional connectivity analysis confirmed that regions associated with trait-processing and individual identities were functionally coupled. Activity during the imagination task, and revealed by functional connectivity, was consistent with the default network. Our results suggest that distinct regions code for personality traits, and that the brain combines these traits to represent individuals. The brain then uses this "personality model" to predict the behavior of others in novel situations.

Senseless is required for pupal retinal development in Drosophila (2004)

Drosophila sensory organs are specified by a family of proneural genes which induce the expression of several common targets. One such target is senseless, which encodes a zinc finger transcription factor. We analyzed the function of senseless during pupal retinal development and found that senseless is required for recruitment of both cone and pigment cells, the pupal-derived ommatidial support cells. We also found that Senseless is expressed in neural precursors shortly after the larval-pupal transition and is both necessary and sufficient for interommatidial bristle development. Furthermore, senseless is the primary target of achaete and scute during interommatidial bristle development. We also identified several differences between the development of interommatidial bristles and other macrochaete. In particular, EGFR signaling is not required for interommatidial bristle development, nor is positive feedback regulation of proneural genes by senseless. A model for interommatidial bristle specification is presented.
The Effect of Linomide, an Immunoregulator in Experimental Autoimmune Diseases, on Humoral Antibody Responses in Mice (1997)

Linomide (quinoline-3-carboxamide), a well tolerated, orally administered compound was recently shown to be effective in the prevention and treatment of several autoimmune diseases in experimental animal models. We have investigated its effect on specific humoral immune responses directed to T-cell-dependent soluble or particulate antigens and to a T cell-independent antigen in several mouse strains. Linomide administered after antigen priming did not affect primary and secondary antibody responses directed to T-cell particulate antigens (SRBC) or soluble antigens given with or without complete Freund's Adjuvant (CFA). Linomide treatment given prior to antigen priming did not affect the antibody response to a soluble antigen (TNP-KLH) given with an adjuvant. In contrast, dose-dependent down regulation of primary antibody responses was observed when T cell-dependent (BSA-dextran) or T-cell-independent (TNP-Ficoll) antigens were administered in an immunogenic form without adjuvant after starting Linomide treatment. The primary anti-SRBC antibody response was also suppressed by high dose Linomide given prior to immunization although normal secondary responses were retained. It is worth noting that no immunosuppressive effects on antibody responses were found at low dose ranges which effectively reversed T cell dependent autoimmune manifestation.
Towards Personalized Task-Oriented Worker Recruitment in Mobile Crowdsensing (2020)

Worker recruitment in mobile crowdsensing systems aims to recruit the most suitable users to perform tasks with high quality and in real-time. Many worker recruitment or task matching mechanisms have been proposed, especially for crowdsourcing platforms, where content information of tasks from the implicit feedback of workers' attendance is extensively exploited to help workers find preferred tasks efficiently. Different from traditional crowdsourcing systems, tasks in mobile crowdsensing systems are usually time-sensitive and location-dependent which also play a crucial role in worker recruitment. However, these context information have not been effectively explored for user recruitment in mobile crowdsensing systems. In this paper, we propose a novel personalized task-oriented worker recruitment mechanism for mobile crowdsensing systems based on a careful characterization of workers' preference. In particular, we fully exploit the content information (e.g., task category, task description) together with the context information (e.g., task time, task location) from the implicit feedback of workers' attendance to accurately model workers' preference on tasks. Moreover, we regard the task-worker fitness prediction as a binary classification problem and utilize the Logit model to integrate the heterogeneous factors into a single framework to predict the matching probability of each task-worker pair. Finally, the workers with the highest matching probability are recruited proactively for each new task. Extensive experiments on real-world datasets demonstrate that the proposed mechanism achieves better performance than the benchmarks.
Ultra-Low NOx Oxygen-enriched Combustion System using Oscillation Combustion Method (2017)

In this study, Periodical combustion method was used to restrain NOx emission at oxygen-enriched combustion. This method periodically changes oxygen concentration in the oxidizer and the oxygen ratio at the same time by controlling the flow rate of air and oxygen periodically to keep same whole oxygen ratio condition of original stationary combustion. In other words, this method switches alternatively two states, state (A) high oxygen ratio with low oxygen concentration, and a state (B) low oxygen ratio with high oxygen concentration alternately. State (A) makes oxidizing atmosphere with relatively low flame temperature, and state (B) high flame temperature with reductive atmosphere.
Applications of laser tapping and laser ultrasonics to aerospace composite structures (2010)

Laser ultrasonics is a well known and mature non-destructive technique for inspecting polymer matrix composites used in aerospace. This technique uses a pulse echo interrogation mode, in which ultrasound is first generated by a pulsed laser and then detected by a second laser coupled to an optical interferometer. While very successful to find delaminations in laminates, difficulties are found for reliably detecting disbonds in honeycomb and foam core structures, particularly when the detachment occurs at the back skin. For this purpose, a novel technique called laser tapping is proposed. Laser tapping is based on the thermoelastic excitation by a pulsed laser of the top skin which bulges and is driven into vibration if it is detached from the material underneath. Laser tapping uses essentially the same hardware as laser ultrasonics but probes in a lower ultrasonic frequency range. Laser ultrasonics and laser tapping can then be advantageously used concurrently. This paper presents examples of applications of a combined laser ultrasonic laser tapping system to honeycomb structures with defects, including delaminations in the skin and skin detachments at the front side and the back side.
On the combination of a linear field free trap with a time-of-flight mass spectrometer (2001)

A new instrument has been developed which combines a rf ring electrode trap and a time-of-flight mass spectrometer (TOF-MS). The wide field free storage volume of such a trap enables the study of low temperature ion-molecule collisions; however it is not straightforward to match the nonlocalized ion cloud to the TOF-MS. For obtaining sufficient mass resolution, a special pulse sequence has been developed to transfer the ions from the whole trap volume to a small region in the vicinity of the exit electrode. Additional compression is achieved via buffer gas relaxation prior to extracting the ions. Using a linear flight path of 57 cm, a mass resolution of about 50 is routinely achieved. The mass range of the whole instrument, which is determined by the operating conditions both of the trap and the TOF-MS, has been estimated to be 3–700 u. The actual characteristics of the instrument such as mass range, resolution, and dynamical range have been determined and the results have been analyzed. As a typical application of the new instrument, the growth of (CO)n+ cluster ions is investigated at 80 K. The simultaneous detection of all masses of interest as a function of storage time allows one to follow in detail the kinetics of the reaction and loss processes involved. Limitations of the method are discussed together with ways to overcome them in an improved setup.
Penetrating Left Thoracoabdominal Trauma (1997)

(1) The incidence of diaphragmatic injuries in association with penetrating left thoracoabdominal trauma is high. (2) The clinical and roentgenographic findings are unreliable at detecting occult diaphragmatic injuries. (3) Laparoscopy is a vital tool for detecting occult diaphragmatic injuries among patients who have no other indications for formal celiotomy.
Predicting Early Stage Drug Induced Parkinsonism using Unsupervised and Supervised Machine Learning (2020)

Drug Induced Parkinsonism (DIP) is the most common, debilitating movement disorder induced by antipsychotics. There is no tool available in clinical practice to effectively diagnose the symptoms at the onset of the disease. In this study, the variations in gait accelerometer data due to the intermittency of tremor at the initial stages is examined. These variations are used to train a logistic regression model to predict subjects with early-stage DIP. The logistic classifier predicts if a subject is a DIP or control with approximately 89% sensitivity and 96% specificity. This paper discusses the algorithm used to extract the features in gait data for training the classifier to predict DIP at the earliest.Clinical Relevance- Diagnosing the disease and the causative drug is vital as the physical health of a patient who is mentally unstable can deteriorate with prolonged usage of the drug. The proposed model helps clinicians to diagnose the disease at the onset of tremors with an accuracy of 93.58%.
