Power Allocation in Multi-Antenna Wireless Systems Subject to Simultaneous Power Constraints (2012)

We address the problem of power allocation to maximize ergodic capacity subject to multiple power constraints assuming that perfect causal channel state information (CSI) is available at both the transmitter and the receiver. We characterize the optimal power allocation subject to both long-term and short-term power constraints, which depends upon the ratio of the two power levels. Additionally, we find a suboptimal power allocation if the input power is subject to long-term and per-antenna power constraints. We characterize the conditions for which one power constraint dominates and the other can be ignored. Numerical results suggest that, for the Rayleigh fading case, a short-term power constraint that is larger than a long-term power constraint does not significantly impact the ergodic capacity of the channel. The effect of per-antenna power constraints is also explored for the case of Rayleigh fading through our numerical results.
Impact of Interface Defect Passivation on Conduction Band Offset at SiO<sub>2</sub>/4H-SiC Interface (2012)

The change in energy band alignment of thermally grown SiO2/4H-SiC(0001) structures due to an interface defect passivation treatment was investigated by means of synchrotron radiation photoelectron spectroscopy (SR-PES) and electrical characterization. Although both negative fixed charge and interface state density in SiO 2 /SiC structures were effectively reduced by high-temparature hydrogen gas annealing (FGA), the conduction band offset (ΔE c ) at the SiO 2 /SiC interface was found to be decreased by about 0.1 eV after FGA. In addition, a subsequent vacuum annealing to induce hydrogen desorption from the interface resulted in not only a slight degradation in interface property but also a partial recovery of ΔE c value. These results indicate that the hydrogen passivation of negatively charged defects near the thermally grown SiO 2 /SiC interface causes the reduction in conduction band offset. Therefore, the tradeoff between interface quality and conduction band offset for thermally grown SiO 2 /SiC MOS structure needs to be considered for developing SiC MOS devices.
<title>Influence of vibrations on Fourier transform spectrometers</title> (1997)

Spaceborne Fourier transform spectrometers (FTSs) are one of the most promising sensors for global measurements of the atmosphere and/or the surface because of its potentialities for high spectral resolution and high accuracy. One of the difficulties for realizing a high performance FTS is how to overcome its performance degradation caused by disturbances such as mechanical vibrations and shocks. We have developed a computer-based simulator to evaluate the performance degradation. Influence of vibrations for various kinds of FTSs using different optical elements and different sampling methods are examined by evaluating spectral measurement errors quantitatively. It is shown that spectral measurement errors of FTSs is restrained by using corner cube reflectors and sampling method defined by laser interference.
Adenosine Deaminase Diagnostic Testing in Pericardial Fluid (2019)

A 65-year-old Vietnamese man with hypertension, type 2 diabetes mellitus, and chronic hepatitis B with cirrhosis presented with a 2-week history of shortness of breath at rest, orthopnea, and lower extremity edema. He reported a 4-month history of nonproductive cough, 5-kg weight loss, and fatigue. He immigrated to the United States as an adult more than 20 years before presentation. His temperature was 37°C, heart rate was 78/min, respiratory rate was 17/min, and blood pressure was 158/95 mm Hg. A chest radiographic image suggested cardiomegaly and a computed tomographic scan demonstrated a moderate to large pericardial effusion. A pericardial drain was placed and pericardial fluid was sent to the laboratory for evaluation. Initial pericardial fluid study results are presented in the Table. Empirical treatment for tuberculosis was initiated. Three days later, an adenosine deaminase (ADA) level of 118.1 U/L (normal range, 0.0-11.3 U/L) from pericardial fluid was reported from the laboratory.

Modifications of the active sites distribution in the Ziegler‐Natta polymerization of propylene using Lewis acids (2010)

Abstract Heterogeneous Ziegler‐Natta precatalysts (with phthalate as internal donor) were modified by treatments with various Lewis acids (MCl n with M = Ga, Sn, Si, and Sb and n = 3, 4, or 5) before their use in the polymerization of propylene. If performed on previously “detitanated” precatalysts, treatments with SnCl 4 and SiCl 4 lead to a slight activation but especially to an increase of the tacticity whereas GaCl 3 and SbCl 5 treatments deactivate the catalyst. The modification method applied to conventional unmodified precatalysts gave similar trends. A significant increase of tacticity (and/or of T m ) and a narrowing of the molecular weight distribution were observed in the case of SnCl 4 and SiCl 4 treatments. © 2010 Wiley Periodicals, Inc.

Targeting IRAK1 in T-Cell acute lymphoblastic leukemia (2015)

T-cell acute lymphoblastic leukemia (T-ALL) represents expansion of cells arrested at specific stages of thymic development with the underlying genetic abnormality often determining the stage of maturation arrest. Although their outcome has been improved with current therapy, survival rates remain only around 50% at 5 years and patients may therefore benefit from specific targeted therapy. Interleukin receptor associated kinase 1 (IRAK1) is a ubiquitously expressed serine/threonine kinase that mediates signaling downstream to Toll-like (TLR) and Interleukin-1 Receptors (IL1R). Our data demonstrated that IRAK1 is overexpressed in all subtypes of T-ALL, compared to normal human thymic subpopulations, and is functional in T-ALL cell lines. Genetic knock-down of IRAK1 led to apoptosis, cell cycle disruption, diminished proliferation and reversal of corticosteroid resistance in T-ALL cell lines. However, pharmacological inhibition of IRAK1 using a small molecule inhibitor (IRAK1/4-Inh) only partially reproduced the results of the genetic knock-down. Altogether, our data suggest that IRAK1 is a candidate therapeutic target in T-ALL and highlight the requirement of next generation IRAK1 inhibitors.
On-Line Chatter Detection Using Wavelet-Based Parameter Estimation (2000)

Abstract A new method for on-line chatter detection is presented. The proposed method characterizes the significant transition from high dimensional to low dimensional dynamics in the cutting process at the onset of chatter. Based on the likeness of the cutting process to the nearly-1/f process, this wavelet-based maximum likelihood (ML) estimation algorithm is applied for on-line chatter detection. The presented chatter detection index γ is independent of the cutting conditions and gives excellent detection accuracy and permissible computational efficiency, which makes it suitable for on-line implementation. The validity of the proposed method is demonstrated through the tests with extensive actual data obtained from turning and milling processes.
Potential Measurements in Acetylide-Containing Melts (1978)

Present data suggest that the free energy of formation of Li/sub 2/C/sub 2/ is -26 kcal/mol at 700/sup 0/K. However, there is no evidence that the discharge of acetylide ions is reversible, i.e., that acetylide ions are formed by direct reduction of carbon. The carbon electrode is susceptible to mixed potentials. Acetylide ion discharge is strongly diffusion controlled. It appears that acetylide ions in LiCl--KCl eutectic are reasonably stable only in the absence of oxidants such as lithium-intercalated graphite. (DLC)
A photoswitchable solvatochromic dye for probing membrane ordering by RESOLFT super-resolution microscopy (2023)

A switchable solvatochromic fluorescent dyad can be used to map ordering of lipids in vesicle membranes at a resolution better than the diffraction limit. Combining a Nile Red fluorophore with a photochromic spironaphthoxazine quencher allows the fluorescence to be controlled using visible light, via photoswitching and FRET quenching. Synthetic lipid vesicles of varying composition were imaged with an average 2.5-fold resolution enhancement, compared to the confocal images. Ratiometric detection was used to probe the membrane polarity, and domains of different lipid ordering were distinguished within the same membrane.
Group 2 innate lymphoid cells are elevated and activated in chronic rhinosinusitis with nasal polyps (2017)

Intrinsic supercurrent non-reciprocity coupled to the crystal structure of a van der Waals Josephson barrier (2023)

Non-reciprocal electronic transport in a spatially homogeneous system arises from the simultaneous breaking of inversion and time-reversal symmetries. Superconducting and Josephson diodes, a key ingredient for future non-dissipative quantum devices, have recently been realized. Only a few examples of a vertical superconducting diode effect have been reported and its mechanism, especially whether intrinsic or extrinsic, remains elusive. Here we demonstrate a substantial supercurrent non-reciprocity in a van der Waals vertical Josephson junction formed with a Td-WTe2 barrier and NbSe2 electrodes that clearly reflects the intrinsic crystal structure of Td-WTe2. The Josephson diode efficiency increases with the Td-WTe2 thickness up to critical thickness, and all junctions, irrespective of the barrier thickness, reveal magneto-chiral characteristics with respect to a mirror plane of Td-WTe2. Our results, together with the twist-angle-tuned magneto-chirality of a Td-WTe2 double-barrier junction, show that two-dimensional materials promise vertical Josephson diodes with high efficiency and tunability.
Photonic crystal microcrystalline silicon solar cells (2015)

Abstract Enhancing the absorption of thin‐film microcrystalline silicon solar cells over a broadband range in order to improve the energy conversion efficiency is a very important challenge in the development of low cost and stable solar energy harvesting. Here, we demonstrate that a broadband enhancement of the absorption can be achieved by creating a large number of resonant modes associated with two‐dimensional photonic crystal band edges. We utilize higher‐order optical modes perpendicular to the silicon layer, as well as the band‐folding effect by employing photonic crystal superlattice structures. We establish a method to incorporate photonic crystal structures into thin‐film (~500 nm) microcrystalline silicon photovoltaic layers while suppressing undesired defects formed in the microcrystalline silicon. The fabricated solar cells exhibit 1.3 times increase of a short circuit current density (from 15.0 mA/cm 2 to 19.6 mA/cm 2 ) by introducing the photonic crystal structure, and consequently the conversion efficiency increases from 5.6% to 6.8%. Moreover, we theoretically analyze the absorption characteristics in the fabricated cell structure, and reveal that the energy conversion efficiency can be increased beyond 9.5% in a structure less than 1/400 as thick as conventional crystalline silicon solar cells with an efficiency of 24%. © 2015 The Authors.

Readthrough acetylcholinesterase (AChE-R) and regulated necrosis: pharmacological targets for the regulation of ovarian functions? (2015)

Proliferation, differentiation and death of ovarian cells ensure orderly functioning of the female gonad during the reproductive phase, which ultimately ends with menopause in women. These processes are regulated by several mechanisms, including local signaling via neurotransmitters. Previous studies showed that ovarian non-neuronal endocrine cells produce acetylcholine (ACh), which likely acts as a trophic factor within the ovarian follicle and the corpus luteum via muscarinic ACh receptors. How its actions are restricted was unknown. We identified enzymatically active acetylcholinesterase (AChE) in human ovarian follicular fluid as a product of human granulosa cells. AChE breaks down ACh and thereby attenuates its trophic functions. Blockage of AChE by huperzine A increased the trophic actions as seen in granulosa cells studies. Among ovarian AChE variants, the readthrough isoform AChE-R was identified, which has further, non-enzymatic roles. AChE-R was found in follicular fluid, granulosa and theca cells, as well as luteal cells, implying that such functions occur in vivo. A synthetic AChE-R peptide (ARP) was used to explore such actions and induced in primary, cultured human granulosa cells a caspase-independent form of cell death with a distinct balloon-like morphology and the release of lactate dehydrogenase. The RIPK1 inhibitor necrostatin-1 and the MLKL-blocker necrosulfonamide significantly reduced this form of cell death. Thus a novel non-enzymatic function of AChE-R is to stimulate RIPK1/MLKL-dependent regulated necrosis (necroptosis). The latter complements a cholinergic system in the ovary, which determines life and death of ovarian cells. Necroptosis likely occurs in the primate ovary, as granulosa and luteal cells were immunopositive for phospho-MLKL, and hence necroptosis may contribute to follicular atresia and luteolysis. The results suggest that interference with the enzymatic activities of AChE and/or interference with necroptosis may be novel approaches to influence ovarian functions.
Regulated Expression of a Complete Human β-Globin Gene Encoded by a Transmissible Retrovirus Vector (1987)

We introduced a human beta-globin gene into murine erythroleukemia (MEL) cells by infection with recombinant retroviruses containing the complete genomic globin sequence. The beta-globin gene was correctly regulated during differentiation, steady-state mRNA levels being induced 5- to 30-fold after treatment of the cells with the chemical inducer dimethyl sulfoxide. Studies using vectors which yield integrated proviruses lacking transcriptional enhancer sequences indicated that neither retroviral transcription nor the retroviral enhancer sequences themselves had any obvious effect on expression of the globin gene. Viral RNA expression also appeared inducible, being considerably depressed in uninduced MEL cells but approaching normal wild-type levels after dimethyl sulfoxide treatment. We provide data which suggest that the control point for both repression and subsequent activation of virus expression in MEL cells lies in the viral enhancer element.

Ocean mixing studied near Hawaiian Ridge (2000)

The Hawaii Ocean Mixing Experiment (HOME) is a grassroots program to study turbulent mixing processes near the Hawaiian Ridge. The HOME is motivated by the desire to understand diffusive aspects of the advective‐diffusive balance that mediates the general circulation of the oceans. HOME is focused on tidally driven mixing, given the ubiquity of the tide as a deep‐sea energy source. As the sea surface cools at high latitude, surface waters sink. Subsidence rate is sufficient to fill the worlds ocean with cold bottom water in approximately 3,000 years. Diffusive processes that transfer heat into the abyssal ocean are required to maintain a steady‐state thermal structure. An effective eddy diffusivity of order K p =10 −4 m 2 s −1 , 700 times the molecular diffusivity of heat, is necessary [ Munk , 1966]. Such a diffusivity might be supported by either mechanical mixing (turbulent transport) or thermodynamic (so‐called doubly diffusive) processes.
Greedy Learning of Markov Network Structure (2012)

We propose a new yet natural algorithm for learning the graph structure of general discrete graphical models (a.k.a. Markov random fields) from samples. Our algorithm finds the neighborhood of a node by sequentially adding nodes that produce the largest reduction in empirical conditional entropy; it is greedy in the sense that the choice of addition is based only on the reduction achieved at that iteration. Its sequential nature gives it a lower computational complexity as compared to other existing comparison-based techniques, all of which involve exhaustive searches over every node set of a certain size. Our main result characterizes the sample complexity of this procedure, as a function of node degrees, graph size and girth in factor-graph representation. We subsequently specialize this result to the case of Ising models, where we provide a simple transparent characterization of sample complexity as a function of model and graph parameters. For tree graphs, our algorithm is the same as the classical Chow-Liu algorithm, and in that sense can be considered the extension of the same to graphs with cycles.

Electrodeposited Light-Emitting Nanojunctions (2013)

Electroluminescent (EL) metal-semiconductor-metal nanojunctions are prepared by electrodepositing nanocrystalline cadmium selenide (nc-CdSe) within ∼250 nm gold (Au) nanogaps prepared by focused ion beam milling. The electrodeposition of nc-CdSe is carried out at two temperatures: 20 °C (“cold”) and 75 °C (“hot”), producing mean grain diameters of 6 ± 1 nm and 11 ± 2 nm, respectively, for the nc-CdSe. Light-emitting nanojunctions (LEnJs) prepared at both temperatures show a low threshold voltage for light emission of <2 V; just above the 1.74 eV bandgap of CdSe. The EL intensity increases with the injection current and hot-deposited LEnJs produced a maximum EL intensity that is an order of magnitude higher than the cold-deposited LEnJs. Emitted photons are bimodal in energy with emission near the band gap of CdSe, and also at energies 200 meV below it; consistent with a mechanism of light emission involving the radiative recombination of injected holes with electrons at both band-edge and defect states. The quantum yield for “hot” electrodeposited nc-CdSe LEnJs is comparable to devices constructed from single crystalline nanowires of CdSe, and the threshold voltage of 1.9 (±0.1) V (cold) and 1.5 (±0.2) V (hot) is at the low end of the range reported for CdSe nanowire based devices.
Direct regulation ofWRKY70byAtMYB44in plant defense responses (2013)

Cross-talk between hormones is required for plant response to developmental cues and environmental stresses. This cross-talk is achieved through several regulators located in convergence point of distinct hormonal signaling. In plant defense responses, salicylic acid and jasmonic acid affect each other in antagonistic manner. In a recent study we showed that AtMYB44 transcription factor positively regulates SA-mediated defense expression and enhanced resistance to Pst DC3000. On the other hand, AtMYB44 negatively regulates expression of JA-mediated defense gene expression and downregulated resistance to Alternaria brassicicola. Effects of AtMYB44 in SA- and JA-mediated defense responses were achieved through direct regulation of WRKY70 expression which acts as an integrator of cross-talk between SA and JA in plant defense responses. Here we provide further evidence that AtMYB44 regulates defense responses by transcriptional activation of downstream gene, WRKY70. This result shows that AtMYB44 is an integrator of cross-talk between SA and JA in plant defense responses.
Genetic Basis of Familial Dyslipidemia and Hypertension: 15-Year Results From Utah (1993)

The genetic and environmental determinants of hypertension, lipid abnormalities, and coronary artery disease (CAD) have been studied for 15 years in Utah in population-based multigenerational pedigrees (2500 subjects among 98 pedigrees), twin pairs (74 monozygous and 78 dizygous), hypertensive siblings (131 sibships), siblings with CAD before age 55 (45 sibships), and anecdotally ascertained pedigrees with type II diabetes (271 subjects among 16 pedigrees), lipoprotein lipase deficiency (106 subjects in a single pedigree), and familial hypercholesterolemia (502 heterozygotes among 50 pedigrees). Estimates of heritability ranged from 20 to 75% for blood pressures and blood lipids. A strong positive family history predicts a future occurrence of hypertension (relative risk [RR] = 3.8) and CAD (RR = 12.7). Segregating single-gene effects were found for several 'intermediate phenotypes' associated with hypertension (erythrocyte sodium-lithium countertransport, intraerythrocytic sodium, a relative fat pattern, total urinary kallikrein excretion, and fasting insulin levels). Strong single-gene effects in segregation analysis were also found for low-density lipoprotein (LDL) cholesterol, lipoprotein (a) (Lp[a]), low high-density lipoprotein (HDL) cholesterol, and high apolipoprotein (apo) B. Deoxyribonucleic acid (DNA) markers of lipid abnormalities or hypertension have included LDL-receptor defects, lipoprotein lipase deficiency, high Lp(a), familial defective apo B, decreased quantitative levels of apo B, apo E phenotype, angiotensinogen, and 'glucocorticoid remediable aldosteronism (GRA) hypertension.' Also tested in Utah studies, but not found to be DNA markers for hypertension, were the genetic loci for the structural genes for renin and angiotensin-converting enzyme, and the sodium antiport system. In addition, important gene-gene interactions (LDL receptor with apo E2) and gene-environment interactions (kallikrein with potassium intake) were found.(ABSTRACT TRUNCATED AT 250 WORDS)
