Effects of pulse and DC charging on lithium iron phosphate (LiFePO<inf>4</inf>) batteries (2013)

Resonant converters which use a small DC bus capacitor to achieve high power factor are desirable for low cost Inductive Power Transfer (IPT) applications but produce amplitude modulated waveforms which are then present on any coupled load. The modulated coupled voltage produces pulse currents which could be used for battery charging purposes. In order to understand the effects of such pulse charging, two Lithium Iron Phosphate (LiFePO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> ) batteries underwent 2000 cycles of charge and discharging cycling utilizing both pulse and DC charging profiles. The cycling results show that such pulse charging is comparable to conventional DC charging and may be suitable for low cost battery charging applications without impacting battery life.
A Motor Learning Paradigm Combining Technology and Associative Learning to Assess Prone Motor Learning in Infants (2019)

Effects of well number, cavity length, and facet reflectivity on the reduction of threshold current of GaAs/AlGaAs multiquantum well lasers (1988)

The optimum design for reducing the threshold current of GaAs/AlGaAs multiquantum well lasers is determined experimentally. The lowest threshold current density is realized by using single and multiquantum wells at long and short cavity lengths, respectively. The threshold current has a minimum at the optimum cavity length: the minimum threshold current is smaller for a larger number of quantum wells, and the optimum cavity length is inversely proportional to the number of wells. Experiments are compared to the theory developed by P.W.A. McIlroy, et al. (ibid., vol.21, no.12, p.1958-63, 1985) and limiting performances of quantum well lasers with various numbers of wells are presented. The reduction of the threshold current by high reflectivity coatings is also demonstrated, and a threshold current as low as 1.86 mA at 15 degrees C is reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Quantifying oxygen induced surface enrichment of a dilute PdAu alloy catalyst (2021)

The surface composition of dilute PdAu catalysts is dynamic and difficult to resolve. Using CO pulse titration, we determine that after oxygen treatment a three-fold enrichment of Pd is seen on the surface of a dilute PdAu catalyst.
Adipose tissue derived stromal stem cell therapy in murine ConA‐derived hepatitis is dependent on myeloid‐lineage and CD4+T‐cell suppression (2013)

Mesenchymal stromal stem cells (MSCs) are an attractive therapeutic model for regenerative medicine due to their pluripotency. MSCs are used as a treatment for several inflammatory diseases, including hepatitis. However, the detailed immunopathological impact of MSC treatment on liver disease, particularly for adipose tissue derived stromal stem cells (ADSCs), has not been described. Here, we investigated the immuno-modulatory effect of ADSCs on hepatitis using an acute ConA C57BL/6 murine hepatitis model. i.v. administration of ADSCs simultaneously or 3 h post injection prevented and treated ConA-induced hepatitis. Immunohistochemical analysis revealed higher numbers of CD11b(+), Gr-1(+), and F4/80(+) cells in the liver of ConA-induced hepatitis mice was ameliorated after the administration of ADSCs. Hepatic expression of genes affected by ADSC administration indicated tissue regeneration-related biological processes, affecting myeloid-lineage immune-mediating Gr-1(+) and CD11b(+) cells. Pathway analysis of the genes expressed in ADSC-treated hepatic inflammatory cells revealed the possible involvement of T cells and macrophages. TNF-α and IFN-γ expression was downregulated in hepatic CD4(+) T cells isolated from hepatitis livers co-cultured with ADSCs. Thus, the immunosuppressive effect of ADSCs in a C57BL/6 murine ConA hepatitis model was dependent primarily on the suppression of myeloid-lineage cells and, in part, of CD4(+) T cells.

DNN-Based Calibration Factor Estimation for Effective SINR Mapping in CQI Selection of 5G NR (2023)

This paper proposes a deep neural network (DNN)-based calibration factor estimation for an effective signal-to-interference-plus-noise ratio (SINR) mapping in a channel quality indicator (CQI) selection of fifth-generation new radio (5G NR). In 5G NR, a receiver can report CQI to a transmitter, and adaptive modulation and coding (AMC) is performed in the transmitter. The CQI can be selected using an effective SINR mapping (ESM) scheme in the receiver. The ESM scheme can compress the received SINRs into an effective SINR. Further, a calibration factor is required to improve the accuracy of ESM. The optimal value of the calibration factor may differ according to the channel environment between the transmitter and receiver. In this paper, the proposed scheme can estimate the optimal calibration factor using the DNN model. Simulation results show that the proposed DNN-based scheme outperforms the conventional scheme using the predefined calibration factor.

Clean Transfer of Wafer-Scale Graphene via Liquid Phase Removal of Polycyclic Aromatic Hydrocarbons (2015)

Pentacene (C22H14), a polycyclic aromatic hydrocarbon, was used as both supporting and sacrificing layers for the clean and doping-free graphene transfer. After successful transfer of graphene to a target substrate, the pentacene layer was physically removed from the graphene surface by using intercalating organic solvent. This solvent-mediated removal of pentacene from graphene surface was investigated by both theoretical calculation and experimental studies with various solvents. The uses of pentacene and appropriate intercalation solvent enabled graphene transfer without forming a residue from the supporting layer. Such residues tend to cause charged impurity scattering and unintentional graphene doping effects. As a result, this clean graphene exhibited extremely homogeneous surface potential profiles over a large area. A field-effect transistor fabricated using this graphene displayed a high hole (electron) mobility of 8050 cm(2)/V·s (9940 cm(2)/V·s) with a nearly zero Dirac point voltage.
Implantable optical biosensor for in vivo molecular imaging (2009)

We present the design and fabrication of an implantable fluorescence biosensor suitable for continuously monitored, freely-moving in vivo rodent studies. The GaAs-based semiconductor sensor incorporates an un-cooled photodetector with a 670nm vertical-cavity surface-emitting laser (VCSEL) optimized for sensing fluorescent Cy5.5 dye. For filtering unwanted spectra, a combination of physical and spectral blocking layers yields OD5 excitation rejection at the detector. The sensor detects near-IR fluorescent Cy5.5 molecules in vitro at 100nM concentration (in a 100&mu;L volume) with linear response for concentrations up to 25&mu;M. In a preliminary study in a living mouse, subcutaneously injected dye (1&mu;M Cy5.5 in 50&mu;L) was detected. This technology has the potential to enable new studies of living systems in applications that require long-term, continuous fluorescence sensing.
The Essential Guide to Realizing 5G-Connected UAVs with Massive MIMO (2019)

What will it take for drones, and the whole associated ecosystem, to take off? Arguably, infallible C&C channels for safe and autonomous flying, and high-throughput links for multi-purpose live video streaming. And indeed, meeting these aspirations may entail full cellular support, provided through 5G-and-beyond hardware and software upgrades by both mobile operators and manufacturers of these UAVs. In this article, we vouch for massive MIMO as the key building block to realize 5G-connected UAVs. Through the sheer evidence of 3GPP-compliant simulations, we demonstrate how massive MIMO can be enhanced by complementary network-based and UAV-based solutions, resulting in consistent UAV C&C support, large UAV uplink data rates, and harmonious coexistence with legacy ground users.
Optics of cholesterics with oblique helicoidal director (2020)

Cholesteric liquid crystals (Ch&rsquo;s) are formed by organic molecules that pack in space into periodic helical structure and are capable to selectively reflect light in the visible part of the spectrum when the period of the helix is in the submicron range. This property is attractive for designing optical elements such as band-pass filters, mirrors, low-threshold lasers, etc. However, the Ch period is hard to tune continuously by electric or magnetic fields. In chiral mixtures of flexible dimers, an applied field can create an oblique helicoidal structure (ChOH) which is stable in a wide range of applied field maintaining its axis parallel to the field (Xiang, J. et.al, Phys. Rev. Lett. 112, 217801 (2014); Xiang, J. et.al, Adv. Mater. 27, 3014 (2015)). Both the ChOH period and the conical angle depend strongly on the field, which enables electrically tunable Bragg reflection in a broad spectral range from ultraviolet to infrared. We explore the Bragg diffraction at the ChOH periodic structure as a function of the electric field, surface anchoring, angle of light incidence, and polarization. In ChOH mixtures doped with azobenzene-based photosensitive compound, we show that the ChOH period can be tuned by UV irradiation because of trans-to-cis isomerization. Finally, Bragg reflection at the ChOH periodic structure can be used to measure elastic constants of Ch phase. The work is supported by NSF grant ECCS-1906104.
Diverse Profiles of Ricin-Cell Interactions in the Lung Following Intranasal Exposure to Ricin (2015)

Ricin, a plant-derived exotoxin, inhibits protein synthesis by ribosomal inactivation. Due to its wide availability and ease of preparation, ricin is considered a biothreat, foremost by respiratory exposure. We examined the in vivo interactions between ricin and cells of the lungs in mice intranasally exposed to the toxin and revealed multi-phasic cell-type-dependent binding profiles. While macrophages (MΦs) and dendritic cells (DCs) displayed biphasic binding to ricin, monophasic binding patterns were observed for other cell types; epithelial cells displayed early binding, while B cells and endothelial cells bound toxin late after intoxication. Neutrophils, which were massively recruited to the intoxicated lung, were refractive to toxin binding. Although epithelial cells bound ricin as early as MΦs and DCs, their rates of elimination differed considerably; a reduction in epithelial cell counts occurred late after intoxication and was restricted to alveolar type II cells only. The differential binding and cell-elimination patterns observed may stem from dissimilar accessibility of the toxin to different cells in the lung and may also reflect unequal interactions of the toxin with different cell-surface receptors. The multifaceted interactions observed in this study between ricin and the various cells of the target organ should be considered in the future development of efficient post-exposure countermeasures against ricin intoxication.
Fibrinogen Receptor (GPIIb-IIIa) Antagonists Derived from 5,6-Bicyclic Templates. Amidinoindoles, Amidinoindazoles, and Amidinobenzofurans Containing the N-α-Sulfonamide Carboxylic Acid Function as Potent Platelet Aggregation Inhibitors (1997)

A series of highly potent and specific fibrinogen receptor antagonists have been discovered and optimized through structural modification of the novel amidinoindole and benzofuran compounds, I and II. Systematic linker optimization afforded the amidinobenzofuran-containing inhibitor 29, which displayed an IC50 value of 250 nM in platelet aggregation assays. Attempts to enhance activity by modification of the beta-position of the beta-alanyl carboxylate group of 29 had only a modest effect on inhibitory activity in aggregation assays. Analogues prepared to enhance the activity by conformational restriction were also found to be equally or less potent. In contrast, modification at the alpha-position of the beta-alanyl carboxylate group resulted in the identification of extremely potent and novel amidinobenzofuran-containing derivatives 46-49. Reexamination of 5,6-bicyclic aromatic nucleus led to the further identification of amidinoindole- and amidinoindazole-containing derivatives 53-55. These analogues, 46-49 and 53-55, exhibited potent in vitro activity with IC50 values of 25-65 nM in platelet aggregation assays and an IC50 value of 2 nM in fibrinogen binding assays and demonstrated a selectivity of > 50,000-fold for GPIIb-IIIa versus the most closely related integrin, the vitronectin receptor, alpha v beta 3.
Validation of patient‐reported warfarin dose in a prospective incident cohort study (2014)

In our population, we found that patient-reported warfarin dose and prescribed warfarin dose were comparable for the conduct of observational and clinical studies as well as for the validation and implementation of warfarin dosing algorithms. Moreover, the effect was similar whether measured in new-onset users of warfarin and after up to 12 months of use.

Control plane design for reliable optical networks (2002)

The application of an IP-based control plane to optical networks has opened up new opportunities and challenges for network designers. Although much work has been done on standardization of protocols for IP networks, the applicability of these protocols to controlling optical networks and the overall reliability of optical networks needs further investigation. This article provides a detailed discussion of a number of subtle protocol design and implementation issues that were not addressed in early standardization efforts or published papers.
Cutting Edge: Hypoxia-Induced Nanog Favors the Intratumoral Infiltration of Regulatory T Cells and Macrophages via Direct Regulation of TGF-β1 (2013)

Emerging evidence suggests a link between tumor hypoxia and immune suppression. In this study, we investigated the role of hypoxia-induced Nanog, a stemness-associated transcription factor, in immune suppression. We observed that hypoxia-induced Nanog correlated with the acquisition of stem cell-like properties in B16-F10 cells. We further show that Nanog was selectively induced in hypoxic areas of B16-F10 tumors. Stable short hairpin RNA-mediated depletion of Nanog, combined with melanocyte differentiation Ag tyrosinase-related protein-2 peptide-based vaccination, resulted in complete inhibition of B16-F10 tumor growth. Nanog targeting significantly reduced immunosuppressive cells (regulatory T cells and macrophages) and increased CD8(+) T effector cells in tumor bed in part by modulating TGF-β1 production. Additionally, Nanog regulated TGF-β1 under hypoxia by directly binding the TGF-β1 proximal promoter. Collectively, our data establish a novel functional link between hypoxia-induced Nanog and TGF-β1 regulation and point to a major role of Nanog in hypoxia-driven immunosuppression.
Base Station Diversity Propagation Measurements at 73 GHz\n Millimeter-Wave for 5G Coordinated Multipoint (CoMP) Analysis (2017)

This paper describes wideband (1 GHz) base station diversity and coordinated\nmultipoint (CoMP)-style large-scale measurements at 73 GHz in an urban\nmicrocell open square scenario in downtown Brooklyn, New York on the NYU\ncampus. The measurements consisted of ten random receiver locations at\npedestrian level (1.4 meters) and ten random transmitter locations at lamppost\nlevel (4.0 meters) that provided 36 individual transmitter-receiver (TX-RX)\ncombinations. For each of the 36 radio links, extensive directional\nmeasurements were made to give insights into small-cell base station diversity\nat millimeter-wave (mmWave) bands. High-gain steerable horn antennas with\n7-degree and 15-degree half-power beamwidths (HPBW) were used at the\ntransmitter (TX) and receiver (RX), respectively. For each TX-RX combination,\nthe TX antenna was scanned over a 120-degree sector and the RX antenna was\nscanned over the entire azimuth plane at the strongest RX elevation plane and\ntwo other elevation planes on both sides of the strongest elevation angle,\nseparated by the 15-degree HPBW. Directional and omnidirectional path loss\nmodels were derived and match well with the literature. Signal reception\nprobabilities derived from the measurements for one to five base stations that\nserved a single RX location show significant coverage improvement over all\npotential beamformed RX antenna pointing angles. CDFs for nearest neighbor and\nBest-N omnidirectional path loss and cell outage probabilities for directional\nantennas provide insights into coverage and interference for future mmWave\nsmall-cells that will exploit macro-diversity and CoMP.\n
The genetic control of polyacetylenes involved in bitterness of carrots (Daucus carota L.): Identification of QTLs and candidate genes from the plant fatty acid metabolism (2022)

The present study increases the current knowledge on the genetics of PA accumulation in carrot roots. Our finding that carrot candidate genes from the fatty acid metabolism are significantly associated with major QTLs for both major PAs, will facilitate future functional gene studies and a further dissection of the genetic factors controlling PA accumulation. Characterization of such candidate genes will have a positive impact on carrot breeding programs aimed at both lowering or increasing PA concentrations in carrot roots.
[Influence of chronic obstructive pulmonary disease on postoperative lung function of lung cancer patients and predictive value of lung perfusion scan]. (2009)

The mean loss of lung function after lobectomy is less in lung cancer patients with COPD than in patients with normal lung function. Lung perfusion scan before operation may help to predict postoperative lung function of lung cancer patients with COPD.
Perturbation analysis of a variable M/M/1 queue: a probabilistic approach (2006)

In this paper, motivated by the problem of the coexistence on transmission links of telecommunications networks of elastic and unresponsive traffic, we study the impact on the busy period of an M/M/1 queue of a small perturbation in the service rate. The perturbation depends upon an independent stationary process ( X ( t )) and is quantified by means of a parameter ε ≪ 1. We specifically compute the two first terms of the power series expansion in ε of the mean value of the busy period duration. This allows us to study the validity of the reduced service rate approximation, which consists in comparing the perturbed M/M/1 queue with the M/M/1 queue whose service rate is constant and equal to the mean value of the perturbation. For the first term of the expansion, the two systems are equivalent. For the second term, the situation is more complex and it is shown that the correlations of the environment process ( X ( t )) play a key role.

Reporting quality of Cochrane systematic reviews with Chinese herbal medicines (2019)

Although the Cochrane SRs of CHM showed reporting compliance with PRISMA checklist, their reporting quality needs improvement, especially about full reporting of CHM interventions and of TCM-related rationales. Reporting guideline of "PRISMA extension for CHM interventions" should be developed thus to improve their quality.
Considerations for the design of a tubular motor for an aerospace application (2011)

This paper deals with the design of high force density tubular linear permanent magnet motors for aerospace applications. The main requirements of aerospace applications such as force density and fault tolerance are considered in a general review of recent high force density linear machines, highlighting the merits and disadvantages of each motor. Analytical considerations, including two dimensional finite element analyses are used to compare the performance of two main tubular machine topologies, namely a single air-gap tubular motor with inset permanent magnets and its double air-gap counterpart. An experimental validation is presented comparing the predicted analytical results with the measured results on a built motor prototype.
