Tailoring Cation Solvation in Electrode-Decoupled Redox Flow Batteries Significantly Enhances Capacity and Cycle Life (2020)

Electrode-decoupled redox flow batteries (ED-RFBs) employ disparate cationic actives in the anolyte and catholyte, significantly expanding the chemical design space for flow batteries. Crossover induced capacity fade in such systems can be mitigated or eliminated by the use of highly permselective anion exchange membranes (AEMs) as separators. Herein, we show that tailoring the solvation shell around the cationic actives aids in significantly reducing crossover and hence capacity fade. A model V-Ce ED-RFB was developed utilizing this paradigm and demonstrated a 30% enhancement in practical volumetric capacity 1 . By substituting sulfuric acid with methanesulfonic acid as the supporting electrolyte for V and Ce in conjunction with a highly permselective polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SEBS) triblock copolymer AEM 2 enabled a &gt;95% reduction in capacity fade compared to previous sulfuric acid systems. Employing the Marcus-Hush kinetic formulation to understand the solvation effects 3 4 , the presence of strongly solvated cations was shown to be the reason for the significantly improved performance. The ED-RFB maintained nearly 100% coulombic efficiency (CE) and ca. 70% energy efficiency (EE) (at a 50 mA.cm -2 galvanostatic charge/discharge current) over 100 cycles. Thus, we demonstrate that judicious selection of the electrolyte composition leads to ED-RFBs with long life, excellent rate capability and stability. References 1. S. Sankarasubramanian, Y.

A Dual-Band Microwave Filter Design for Modern Wireless Communication Systems (2019)

Nowadays, modern communication system relies on the designs of high-performance devices to enhance communication effect for a high quality of life and smart city system. As a crucial signal processing step, microwave filter removes unwanted frequency components away from the received signal and enhances the useful ones. However, large loss, bulky size, and single-band greatly limit the practical applications in urban computing. Therefore, the filters with dual-band characteristic are highly desirable for modern wireless communication, such as device-to-device communication, environment monitoring, and automatic driving. In this paper, a dual-band microwave filter is designed and fabricated based on the theory of Mie-resonance extraordinary transmission. An electromagnetic wave cannot propagate through a subwavelength aperture drilled in a metallic film. By adding two dielectric cuboids of different sizes into the two apertures, two passbands appear in the frequency range of 10.0-12.0 GHz. In this range, the insertion loss is less than 0.4 dB, and 3-dB bandwidth is more than 48 MHz. Particularly, the two passband frequencies can be tuned by adjusting the size of the dielectric cuboids. This approach opens a way for designing tunable dual-band microwave bandpass filter, which is benefit for enhancing spectrum resource utilization.

Enhancement of Memory Retrieval and Attenuation of Scopolamine‐Induced Amnesia Following Administration of 5‐HT3 Antagonist ICS 205‐930 (1991)

Experimental evidence suggests an important role of serotonin in the process of learning and memory. The present study investigated the effect of 5HT3-receptor antagonist (ICS 205-930) on retrieval of a previously learned aversive habit in the mouse. The effect of ICS 205-930 on scopolamine (3 mg/kg) induced amnesia was also studied. ICS 205-930 (1, 10 & 100 micrograms/kg) produced a dose-dependent increase in latency to cross into the dark chamber. The scopolamine induced memory impairment was significantly attenuated by ICS 205-930 (10 micrograms/kg). These results suggest that memory deficits may be susceptible to attenuation with non-cholinergic treatments.
Nonenzymatic browning reactions of dihydroxyacetone with amino acids or their esters. (1980)

Nonenzymatic browning reactions between dihydroxyacetone (DHA) and amino acids were investigated using buffers as solvents. Regardless of the type of amino acid, DHA was much more reactive than glucose or xylose. Among amino acids tested, lysine was most reactive. The rate of browning was maximum around a DHA-amino acid molar ratio of 1.5, when the total concentration of DHA plus amino acid was constant at 0.1M. When aqueous alcohols were used as solvents, the browning intensity in the reaction between DHA and proline or amino acid ester increased exponentially with a decrease in water content.
Tris-pyridylmethylamine (TPMA) complexes functionalized with persistent nitronyl nitroxide organic radicals (2020)

The chance to have persistent organic radicals in combination with metals has attracted much interest since it offers the possibility of having new functional molecules with multiple open-shell elements. In this study, we report the synthesis of two tripodal tris(2-pyridyl)methylamine ligands (TPMA) functionalized with nitronyl nitroxide persistent radicals. The newly formed ligands have been used to coordinate zinc(ii), copper(ii), iron(ii) and cobalt(ii). The resulting complexes have been investigated by means of electron paramagnetic resonance (EPR), ESI-MS, FT-IR spectroscopy and X-ray diffraction. An electron reduction of the N-O radical moiety has been observed, depending on the metal used for the formation of the complex and the reaction conditions. We have observed small differences in the EPR spectra depending on the meta or para position of the radical moiety in the complex structure and some antiferromagnetic interactions between the paramagnetic M(ii) ions and the radical species.
Adaptive Task Partitioning at Local Device or Remote Edge Server for Offloading in MEC (2020)

Mobile edge computing (MEC) is one of the promising solutions to process computational-intensive tasks for the emerging time-critical Internet-of-Things (IoT) use cases, e.g., virtual reality (VR), augmented reality (AR), autonomous vehicle. The latency can be reduced further, when a task is partitioned and computed by multiple edge servers' (ESs) collaboration. However, the state-of-the-art work studies the MEC-enabled offloading based on a static framework, which partitions tasks at either the local user equipment (UE) or the primary ES. The dynamic selection between the two offloading schemes has not been well studied yet. In this paper, we investigate a dynamic offloading framework in a multi-user scenario. Each UE can decide who partitions a task according to the network status, e.g., channel quality and allocated computation resource. Based on the framework, we model the latency to complete a task, and formulate an optimization problem to minimize the average latency among UEs. The problem is solved by jointly optimizing task partitioning and the allocation of the communication and computation resources. The numerical results show that, compared with the static offloading schemes, the proposed algorithm achieves the lower latency in all tested scenarios. Moreover, both mathematical derivation and simulation illustrate that the wireless channel quality difference between a UE and different ESs can be used as an important criterion to determine the right scheme.
Characterization of Influenza A Outbreaks in Minnesota Swine Herds and Measures Taken to Reduce the Risk of Zoonotic Transmission (2011)

Influenza A virus infections commonly cause respiratory disease in swine and can be transmitted between people and pigs, with potentially novel strains introduced into herds and spilling back into the human population. The goals of this study were to characterize influenza infections in Minnesota pigs and assess biosecurity measures used by swine workers. Veterinarians submitting influenza-positive swine samples to the University of Minnesota Veterinary Diagnostic Laboratory between October 2007 and April 2009 were surveyed regarding disease-related information and biosecurity procedures at each farm. Influenza-positive samples were submitted year-round, peaking in spring and fall. H1N1 was the most commonly detected subtype (56%), followed by H3N2 (14%) and H1N2 (12%). Most positive submissions were associated with illness in growing pigs (median age 8.8 weeks, IQR 5-15). Median morbidity and mortality were 25% (IQR 10-48) and 2% (IQR 0.5-3.5), respectively. Vaccination of sows and growing pigs was conducted at 71% and 7.9% of the swine farms, respectively. Specialized footwear was reported as the most common form of protective equipment used by workers. Employee vaccination for seasonal influenza was 19%. The sow vaccination rate in this study is consistent with national data, although growing pig vaccination is lower than the national average. Seasonal and age trends identified here may provide diagnostic guidance when growing pigs experience respiratory disease. Inconsistent use of protective equipment and employee vaccination at swine farms indicates the need for further discussion and research of approaches to minimize interspecies influenza transmission on swine farms.

Fatigue Crack Propagation Model of Asphalt Concrete Based on Viscoelastic Fracture Mechanics (2010)

A fatigue crack propagation model of asphalt mixtures is developed on the basis of viscoelasticity and fracture mechanics. The fatigue model is extended from the generalized J-integral model proposed previously by the authors to consider the effects of temperature and air void. Laboratory fatigue crack propagation tests for three different asphalt mixtures are performed at various loading conditions, air voids, and temperatures. The test results indicate that the J-integral could take care of the loading magnitude and frequency dependence of the crack speed but could not consider temperature dependence completely. The air void and temperature effects on crack propagation in asphalt mixtures are investigated. Generally the crack propagation of the asphalt mixtures is developed more quickly at high temperatures and large air voids. Finally, the generalized J-integral model is extended by employing a regression function to take care of the temperature and air void effects. The resulting model could provide a reasonable prediction of fatigue crack propagation lives of the asphalt mixtures under various loading and temperature conditions.
A General Synthetic Strategy for Neutral Phosphorus‐Containing Dendrimers (1994)

Clinical Practice: Diagnosis and Evaluation of Dyspepsia (2010)

The main issue regarding the approach to the patient with uninvestigated dyspepsia is whether the symptoms are the result of an important clinical illness, which then determines the appropriate management strategy for the treatment of the symptoms. An initial trial of empiric antisecretory drugs is recommended for those without Helicobacter pylori infection and no alarm symptoms, whereas H. pylori eradication is recommended for those with an active H. pylori infection. Treatment expectations for H. pylori infections should theoretically be similar to other common infectious diseases. In most regions, clarithromycin resistance has undermined traditional triple therapy so that it is no longer a suitable choice as an empiric therapy. Four drug therapies, such as sequential, concomitant, and bismuth-quadruple therapy are generally still acceptable choices as empiric therapies. Posteradication testing is highly recommended to provide early identification of otherwise unrecognized increasing antimicrobial resistance. However, despite the ability to successfully cure H. pylori infections, a symptomatic response can be expected in only a minority of those with dyspepsia not associated with ulcers (so called nonulcer dyspepsia). Overall, from the patients stand point, symptomatic relief is often difficult to achieve and physicians must rely on reassurance along with empiric and individualized care.
Wide magnetic field range of Ni-P/PZT/Ni-P cylindrical layered magnetoelectric composites (2014)

The Ni-P/PZT/Ni-P cylindrical layered magnetoelectric (ME) composites were prepared by electroless deposition. The Ni-P layer has an amorphous nanocrystalline structure. The ME effect in the axial mode of the Ni-P/PZT/Ni-P cylindrical layered composites is similar to that of Ni/PZT/Ni. The Ni-P/PZT/Ni-P composite has lower bias magnetic field of 120 Oe to induce a maximum αE,A and 0.5 kOe to generate αE,A linear increase at the resonance frequency, which may be related to the high permeability of the Ni-P layer. This discovery contributes to the ME devices miniaturization and expands the magnetic field detection range at both low and high magnetic fields.
ELECTRON-BEAM INDUCED CENTERS IN HYDROGENATED AMORPHOUS SILICON (1981)

Photoluminescence was used to compare the effects of low-energy electron bombardment and laser irradiation in a-Si:H. The main effects are similar : 1) decrease of the main luminescence peak at 1.2 eV, 2) enhancement of luminescence at 0.8 eV, and 3) complete recovery of the original properties after annealing at 200°C. The decrease at 1.2 eV however, is much more pronounced with electron than with photon irradiation.

Adherence of oral streptococci to salivary glycoproteins (1992)

We used an overlay method to study the ability of human salivary glycoproteins to serve as receptors for several strains of streptococci that colonize the oral cavity. Parotid and submandibular-sublingual salivas were collected as ductal secretions, separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and transferred to nitrocellulose membranes. The resulting blots were overlaid with [35S]methionine-labeled bacteria, and salivary components to which the bacteria bound were detected by autoradiography. Potential glycoprotein receptors were identified for 8 of the 16 strains tested. In three cases (Streptococcus sanguis 72-40 and 804 and Streptococcus sobrinus OMZ176), highly specific interactions with a single salivary component were detected. Removal of sialic acid residues from the low-molecular-weight salivary mucin prevented adherence of one of these strains (S. sanguis 72-40), suggesting that this saccharide either mediates binding or is a critical component of the receptor site. In the remaining five strains (Streptococcus gordonii G9B and 10558, S. sanguis 10556, and Streptococcus oralis 10557 and 72-41), interactions with multiple salivary components, including the low-molecular-weight salivary mucin, highly glycosylated proline-rich glycoproteins, and alpha-amylase, were detected. These results suggest that some oral streptococci can bind specifically to certain of the salivary glycoproteins. The interactions identified may play an important role in governing bacterial adherence and clearance within the oral cavity.
Transport of platelets induced by red blood cells based on mixture theory (2017)

Thrombosis is a common complication following the surgical implantation of blood contacting devices, and is strongly influenced by the phenomenon of near-wall enrichment of platelets. This paper describes a multi-constituent continuum approach to study this phenomenon. A mixture-theory model is used to describe the motion of the plasma and the red blood cells (RBCs) and the interactions between the two components. A transport model is developed to study the influence of the RBC field on the platelets. The model is used to study blood flow in a rectangular micro-channel, a sudden expansion micro-channel, and a channel containing micro crevices (representing a practical problem encountered in most blood-wetted devices). The simulations show that in the rectangular channel the concentration of platelets near the walls is about five times higher than the concentration near the centerline of the channel. It is also noticed that in the channel with crevices, extremely a large number of platelets accumulate in the deep part of the crevices and this may serve as the nidus for thrombosis occurring in medical devices.

Expression of a Functional Secreted YopN-TyeA Hybrid Protein in Yersinia pestis Is the Result of a +1 Translational Frameshift Event (2004)

YopN is a secreted protein that prior to secretion directly interacts with the cytosolic SycN/YscB chaperone complex and TyeA. This study identifies a secreted YopN-TyeA hybrid protein that is expressed by Yersinia pestis, but not by Yersinia enterocolitica. DNA sequence analysis and site-directed mutagenesis studies demonstrate that the hybrid protein is the result of a +1 translational frameshift event.
Efficient gene delivery into the embryonic chicken brain using neuron-specific promoters and in ovo electroporation (2022)

We demonstrated that exogenous DNA can be effectively introduced into neuronal cells in living embryos by in ovo electroporation with constructs containing neuron-specific promoters. In ovo electroporation offers an easier and more efficient way to manipulate gene expression during embryonic development, and this technique will be useful for neuron-targeted transgene expression.
Spherical Wrapping of a Linear Polyether around a Cation—1,20‐Bis(8‐quinolyloxy)‐3,6,9,12,15,18‐hexaoxaeicosane·RbI (1979)

Complexs of very long polythers and alkali metal salts can be predicted to have two types of structures: 1) the polyether could wrap spherically around the cation and thus shield it from the anion, and 2) the polyether could adopt an S-shaped arrangement with each loop coordinating a cation, which is still bound to an anion for geometric reasons. These two types have been accomplished in (1) (cation: Rb+) and (2) (salt: 2KSCN).
Locus-Specific Analysis of Human Leukocyte Antigen Class I Expression in Melanoma Cell Lines (1994)

Surface expression of human leukocyte antigen (HLA) class I antigens on melanoma lines was evaluated by locus-specific monoclonal antibodies (mAbs) with three different techniques: Fluorescence-activated cell sorting (FACS), immunohistochemistry with cytospin preparation (ICP), and complement-mediated cytotoxicity (CMC). Eleven HLA class I-expressing cell lines developed from metastases were used. Specific expression of HLA loci was examined under routine culture conditions and after 48-h incubation in interferon-gamma (IFN-gamma; 500 U/ml). Loss of allelic expression was seen in one line (586-MEL): Products of genes coding for HLA-A29 and -B44, in strong linkage disequilibrium, were not detectable. HLA-A antigens were consistently detected by all methodologies and minimally affected by pretreatment with IFN-gamma. HLA-B antigens were detectable in 8 of 11 lines by ICP and 3 of 11 lines by CMC. By FACS the supratypic specificity HLA-Bw6 was expressed at low levels in most lines (mean fluorescence 47.2 +/- 13.4 and rose to 259.8 +/- 45.9 after incubation with IFN-gamma; p < 0.001). HLA-Cw antigen detection by CMC correlated with HLA-B (p < 0.01), suggesting that down-regulation and sensitivity to IFN-gamma are shared by the two loci. This low expression of the HLA-B antigens may play a role in the evasion of the host immune response and its up-regulation may be useful in allowing tumor antigen recognition.
Analysis of Early Host Responses for Asymptomatic Disease Detection and Management of Specialty Crops (2010)

The rapid and unabated spread of vector-borne diseases within US specialty crops threatens our agriculture, our economy, and the livelihood of growers and farm workers. Early detection of vector-borne pathogens is an essential step for the accurate surveillance and management of vector-borne diseases of specialty crops. Currently, we lack the tools that would detect the infectious agent at early (primary) stages of infection with a high degree of sensitivity and specificity. In this paper, we outline a strategy for developing an integrated suite of platform technologies to enable rapid, early disease detection and diagnosis of huanglongbing (HLB), the most destructive citrus disease. The research has two anticipated outcomes: i) identification of very early, disease-specific biomarkers using a knowledge base of translational genomic information on host and pathogen responses associated with early (asymptomatic) disease development; and ii) development and deployment of novel sensors that capture these and other related biomarkers and aid in presymptomatic disease detection. By combining these two distinct approaches, it should be possible to identify and defend the crop by interdicting pathogen spread prior to the rapid expansion phase of the disease. We believe that similar strategies can also be developed for the surveillance and management of diseases affecting other economically important specialty crops.
