An Innovative EHD Conduction Pumping Design for Swirl Flow Generation (2021)

Electrohydrodynamics (EHD) offers a variety of methods for enhancing heat transfer, including dielectric fluid pumping and vapor extraction. EHD is characterized by the interaction between fluid flows and electric fields. One such method of pumping is EHD conduction pumping, which takes advantage of the accumulation of heterocharge layers near the electrodes to create a coulomb force which drives the liquid. Existing EHD conduction pump designs have utilized a perforated electrode, a single channel with multiple electrode pairs, or various in-plane designs. A new EHD conduction pump design with helical electrodes inside a circular tube is proposed. A 3D numerical model of the design is developed and used to explore the performance of the pump. Results for static pressure generation, flow generation, and resultant rotational flow are presented. This design is of particular interest, for its potential enhancement of heat and mass transfer and for applications of mixing. It also has potential benefits for manufacturability due to continuous wrapped electrodes rather than multiple electrode pairs.
PHOTOCHEMICAL LINKAGE OF ANTIBODIES TO SILICON CHIPS (1995)

Antibodies and antigen binding fragments thereof were photochemically immobilized on surface-modified silicon chips of 5 x 5 mm size. Silicon surface-grafted diazirines and benzophenones formed covalent bonds with the immunoreagents on light activation. Photolithographic immobilization of monoclonal antibodies in aqueous media was achieved on silicon chips by activating surface-grafted benzophenones. The presence of bovine serum albumin during irradiation reduced nonspecific adsorption of the immunoreagents and retained the immunoactivity of the photoimmobilized molecules.
Novel packet scheduling for supporting various real-time IoT applications in LTE networks (2017)

Recently, LTE networks are attracting a great deal of attention as a platform for real-time IoT applications. Individual devices such as vehicles, drones, and sensors can exchange real-time information with each other on this platform. For example, vehicles periodically provide each other with their real-time location information to avoid automobile collision. 3GPP stipulates that the deadline for vehicle-collision avoidance is 100 msec. In LTE networks, since the throughput of the wireless section fluctuates depending on the wireless channel quality, the time required for each direction differs. To support these various use cases on the platform, it is important to improve the total amount of application data that meets its deadline - we call the metric for this the goodput. However, in LTE networks, conventional MAC schedulers such as the Proportional Fair can obtain only very low goodput when the network load is increased. In this paper, we propose a novel packet scheduling method that adaptively prioritizes each item of application data on the basis of uplink/downlink deadlines and wireless channel quality by adjusting the deadlines. We evaluate our proposed method on NS-3 and find that our proposed method outperforms the conventional Proportional Fair method, which is the most implemented method on eNB.

Lasso Regression: Estimation and Shrinkage via Limit of Gibbs Sampling (2014)

The application of the lasso is espoused in high-dimensional settings where only a small number of the regression coefficients are believed to be nonzero. Moreover, statistical properties of high-dimensional lasso estimators are often proved under the assumption that the correlation between the predictors is bounded. In this vein, coordinatewise methods, the most common means of computing the lasso solution, work well in the presence of low to moderate multicollinearity. The computational speed of coordinatewise algorithms degrades however as sparsity decreases and multicollinearity increases. Motivated by these limitations, we propose the novel "Deterministic Bayesian Lasso" algorithm for computing the lasso solution. This algorithm is developed by considering a limiting version of the Bayesian lasso. The performance of the Deterministic Bayesian Lasso improves as sparsity decreases and multicollinearity increases, and can offer substantial increases in computational speed. A rigorous theoretical analysis demonstrates that (1) the Deterministic Bayesian Lasso algorithm converges to the lasso solution, and (2) it leads to a representation of the lasso estimator which shows how it achieves both $\ell_1$ and $\ell_2$ types of shrinkage simultaneously. Connections to other algorithms are also provided. The benefits of the Deterministic Bayesian Lasso algorithm are then illustrated on simulated and real data.

Cache-Aided Communications With Multiple Antennas at Finite SNR (2018)

We study the problem of cache-aided communication for cellular networks with multi-user and multiple antennas at finite signal-to-noise ratio. Users are assumed to have non-symmetric links, modeled by wideband fading channels. We show that the problem can be formulated as a linear program, whose solution provides a joint cache allocation along with pre-fetching and fetching schemes that minimize the duration of the communication in the delivery phase. The suggested scheme uses zero-forcing and cached interference subtraction, and hence, allows each user to be served at the rate of its own channel. Thus, this scheme is better than the previously published schemes that are compromised by the poorest user in the communication group. We also consider a special case of the parameters for which we can derive a closed form solution and formulate the optimal power, rate, and cache optimization. This special case shows that the gain of MIMO coded caching goes beyond the throughput. In particular, it is shown that in this case, the cache is used to balance the users such that fairness and throughput are no longer contradicting. More specifically, in this case, strict fairness is achieved jointly with maximizing the network throughput.
Magnetic disaccommodation between 30 and 300 K in low-temperature neutron-irradiated iron (1979)

Magnetic after effect measurements are made on α-iron samples after neutron irradiation at 77 K to a dose of 1.98 × 1022 neutrons m−2. The various relaxations which occur are analysed and their correlated annealing behaviours are also investigated. Since vacancies are generally considered to be immobile below room-temperature, these relaxations are discussed in terms of interstitial and interstitial agglomerate relaxations. Magnetische Nachwirkungsmessungen werden an α-Eisen nach Neutronenbestrahlung bei 77 K bis zu einer Dosis von 1,98 × 1022 Neutronen m−2 durchgeführt. Die verschiedenen stattfindenden Relaxationen werden analysiert und ihre korrelierten Erholungsverhalten untersucht. Da Leerstellen im allgemeinen unterhalb von Raumtemperatur unbeweglich sind, werden die Relaxationen an Hand von Zwischengitteratomen und Zwischengitteratomagglomeraten diskutiert.

Stereoselective Peptide Modifications via β-C(sp3)-H Arylations (2016)

Palladium-catalyzed stereoselective β-arylations of phenylalanine, proline- and pipecolinic acid-containing peptides are a versatile tool for peptide modifications. The reactions proceed without epimerization of stereogenic centers in the peptide chain. If suitable functionalized aryl iodides are introduced, subsequent cross coupling reactions can be used for further modifications. The 8-amino quinoline (AQ) directing group can easily be removed, allowing the prolongation of the peptide chain at the C-terminus.
Daily relations among affect, urge, targeted naltrexone, and alcohol use in young adults. (2016)

Heavy drinking among young adults is a serious public health problem. Naltrexone, an opioid antagonist, has been shown to reduce drinking in young adults compared to placebo and can be taken on a targeted (i.e., as needed) basis. Understanding risk factors for drinking and naltrexone effects within-person in young adults may help to optimize the use of targeted naltrexone. The current study was a secondary analysis of daily diary data from 127 (n = 40 female) young adults (age 18-25) enrolled in a double-blind clinical trial of daily (25 mg) plus targeted (25 mg) naltrexone versus placebo. Hierarchical linear models were used to examine the effects of daily affect, urge, and taking targeted medication on same-day risk of drinking to intoxication (defined as estimated blood-alcohol-concentration, BAC ≥ .08 g%). Results indicated urge significantly mediated within-person positive affect-drinking relations on a daily level. Specifically, positive affect was associated with greater urge to drink, which in turn was associated with greater odds of BAC ≥ .08 g%. Furthermore, days of greater positive affect and urge were associated with taking a targeted dose of medication, which reduced the likelihood of intoxication by nearly 23% in the naltrexone group compared to placebo. Gender and family history of alcohol dependence were examined as moderators of these daily level effects. These results provide further evidence of naltrexone's ability to reduce alcohol consumption in young adults and identify potential within-person risk processes related to heavy drinking that could inform alcohol-related interventions for this population.

Novel high-temperature, high-vacuum, all-metal sample cells for microcalorimetric measurements of solids (1997)

The design of a novel microcalorimetric sample cell which allows rapid transfer of heat from the sample to the cell wall is described. The solid sample is dispersed around the internal walls of the cell. Since the thermopiles of the microcalorimeter are in contact with the outer surface of the cell, the new design of the cell allows rapid recording of the heat generated by the sample. The robust all-metal cell allows in situ sample activation under conditions of high vacuum and at temperatures up to 500 °C. The dispersion of the sample avoids any “deep bed” effects where gas may not be able to diffuse freely to the surface of all of the sample, which may be the case when a thick layer or plug of the sample is used. The cell enables faster acquisition of heat data and minimizes effects of self-heating of the sample. A simple tool, which assists the introduction of the solid sample into the cell and a compact resistor-element, which fits inside the cell for calibration, are described.

Dental water quality--the scientific evidence for current CDC guidelines. (2006)

Newly revised and updated guidelines from the Centers for Disease Control and Prevention recommend adoption of procedures to improve the microbiological quality of water used in dental treatment. These recommendations represent the consensus of experts from a wide range of scientific and clinical disciplines and are based on the best currently available evidence. Dentists and the manufacturers of dental equipment must consider the infection control, occupational health and risk-management implications of biofilm colonization in dental equipment, and take appropriate measures to provide water of appropriate microbiological quality clinical procedures.

Vitamin D deficiency and anemia: a cross-sectional study (2009)

Vitamin D has been suggested to have an effect on erythropoiesis. We sought to evaluate the prevalence of anemia in a population of individuals with vitamin D deficiency compared with those with normal levels in a population of a large integrated healthplan. A cross-sectional analysis in the period 1 January 2004 through 31 December 2006 of subjects with documented concurrent levels of 25-hydroxyvitamin D and hemoglobin were evaluated. Vitamin D deficiency was defined as <30 ng/mL and anemia was defined as a hemoglobin <11 g/dL. A total of 554 subjects were included in the analysis. Anemia was present in 49% of 25-hydroxyvitamin D-deficient subjects compared with 36% with normal 25-hydroxyvitamin D levels (p < 0.01). Odds ratio for anemia in subjects with 25-hydroxyvitamin D deficiency using logistic regressions and controlling for age, gender, and chronic kidney disease was 1.9 (95% CI 1.3-2.7). 25-hydroxyvitamin D-deficient subjects had a lower mean Hb (11.0 vs. 11.7; p = 0.12 ) and a higher prevalence of erythrocyte stimulating agent use (47% vs. 24%; p < 0.05). This study demonstrates an association of vitamin D deficiency and a greater risk of anemia, lower mean hemoglobin, and higher usage of erythrocyte-stimulating agents. Future randomized studies are warranted to examine whether vitamin D directly affects erythropoiesis.
Proactive Application Rate Requirement Adaptation Mechanism for Sidelinks (2021)

Advanced wireless communication use cases relying on sidelinks require guaranteed network performance. However, fulfilling the desired Quality-of-Service (QoS) requirements can-not be always ensured due to factors such as varying interference and dynamicity in the network. To reduce the impact of varying network performance on sidelink applications, we address the problem of long-term proactive adaptation of sidelink applications based on network performance. Specifically, we propose a modular algorithmic framework comprising of data-driven prediction models and model-based optimization to predict the feasibility of given application data rate requirements. Further-more, the framework is capable of predicting the simultaneously achievable data rate demands (in the max-min sense). A vehicular communication scenario is considered as an example to show the applicability of the framework. Evaluations show that variations in feasibility and achievable data rate demands can be well captured to enable robust application layer adaptations.
A double negative (DNG) index composite structure from non-conducting materials with an application to controllable surfaces (2004)

A novel approach for obtaining left-handed material behavior is presented. In this paper, we study a composite-medium model of insulating magnetic-dielectric spherical particles embedded in a background dielectric matrix. We show that the effective permeability and permittivity of the mixture can be simultaneously negative for wavelengths where the spherical inclusions are resonant, thus forming an effective double negative index material. This material is simpler to construct than structures used in previous work. We indicate how we can tune the material behavior to make it relatively broadband. The use of these non-conducting metamaterials can be used to develop "smart" or controllable surfaces.
Determination of Intrinsic Transcription Termination Efficiency by RNA Polymerase Elongation Rate (1994)

Transcription terminators recognized by several RNA polymerases include a DNA segment encoding uridine-rich RNA and, for bacterial RNA polymerase, a hairpin loop located immediately upstream. Here, mutationally altered Escherichia coli RNA polymerase enzymes that have different termination efficiencies were used to show that the extent of transcription through the uridine-rich encoding segment is controlled by the substrate concentration of nucleoside triphosphate. This result implies that the rate of elongation determines the probability of transcript release. Moreover, the position of release sites suggests an important spatial relation between the RNA hairpin and the boundary of the terminator.

Isolation and Synthesis of Laxaphycin B-Type Peptides: A Case Study and Clues to Their Biosynthesis (2015)

The laxaphyci's B family constitutes a group of five related cyclic lipopeptides isolated from diverse cyanobacteria from all around the world. This group shares a typical structure of 12 amino acids from the l and d series, some of them hydroxylated at the beta position, and all containing a rare beta-amino decanoic acid. Nevertheless, they can be differentiated due to slight variations in the composition of their amino acids, but the configuration of their alpha carbon remains conserved. Here, we provide the synthesis and characterization of new laxaphycin B-type peptides. In doing so we discuss how the synthesis of laxaphycin B and analogues was developed. We also isolate minor acyclic laxaphycins B, which are considered clues to their biosynthesis.
