Robust Topology Control in Multi-Hop Cognitive Radio Networks (2014)

The opening of under-utilized spectrum creates the opportunity of substantial performance improvement through cognitive radio techniques. However, the real network performance may be limited since unlicensed users must vacate and switch to other available spectrum if the current spectrum is reclaimed by the licensed (primary) users. During spectrum switching, network partitions may occur since multiple links may be affected if they use the channel reclaimed by the primary users. In this paper, we address this problem through robust topology control, where channels are assigned to minimize channel interference while maintaining network connectivity when primary users appear. The problem is proved to be NP-hard and a sufficient condition for a robust channel assignment is derived. To solve this problem, we first propose centralized algorithms which can reduce the channel interference while satisfying the robustness constraints. Moreover, we derive its performance bound on channel interference and its computational overhead through theoretical analysis. Then, we propose distributed algorithms based on channel hopping techniques, and prove their correctness. Simulation results show that our solutions outperform existing interference-aware approaches substantially when primary users appear and achieve similar performance at other times.
RipTide: A Programmable, Energy-Minimal Dataflow Compiler and Architecture (2022)

Emerging sensing applications create an unprecedented need for energy efficiency in programmable processors. To achieve useful multi-year deployments on a small battery or energy harvester, these applications must avoid off-device communication and instead process most data locally. Recent work has proven coarse-grained reconfigurable arrays (CGRAs) as a promising architecture for this domain. Unfortunately, nearly all prior CGRAs support only computations with simple control flow and no memory aliasing (e.g., affine inner loops), causing an Amdahl efficiency bottleneck as non-trivial fractions of programs must run on an inefficient von Neumann core.RipTide is a co-designed compiler and CGRA architecture that achieves both high programmability and extreme energy efficiency, eliminating this bottleneck. RipTide provides a rich set of control-flow operators that support arbitrary control flow and memory access on the CGRA fabric. RipTide implements these primitives without tagged tokens to save energy; this requires careful ordering analysis in the compiler to guarantee correctness. RipTide further saves energy and area by offloading most control operations into its programmable on-chip network, where they can re-use existing network switches. RipTide’s compiler is implemented in LLVM, and its hardware is synthesized in Intel 22FFL. RipTide compiles applications written in C while saving 25% energy v. the state-of-the-art energy-minimal CGRA and 6.6 × energy v. a von Neumann core.
Apparent Congenital Athyreosis Contrasting with Normal Plasma Thyroglobulin Levels and Associated with Inactivating Mutations in the Thyrotropin Receptor Gene: Are Athyreosis and Ectopic Thyroid Distinct Entities?1 (1998)

Loss-of-function mutations in the TSH receptor gene (TSH-R), usually leading to asymptomatic hyperthyrotropinemia, have been reported since 1995 in a total of eight pedigrees, with a pattern of transmission suggesting autosomal recessive inheritance. Although normal TSH secretion and action are not necessary for normal migration of the thyroid analage, they are essential for normal thyroid growth and function. In keeping with this concept, we report a severely hypothyroid boy with a normally located but very hypoplastic and hypofunctional thyroid caused by TSH-R loss-of-function mutations. The propositus' maternal great aunt also had apparent athyreosis. The propositus had undetectable uptake on 99mpertechnetate scintigraphy but normal plasma thyroglobulin at 15 days of age. He was found to be a compound heterozygote for TSH-R mutations, with the maternal allele carrying a splicing mutation (G to C transversion at position +3 of the donor site of intron 6) and the other allele a deletion of two nucleotides (2 bases of codon 655 in exon 10). The great aunt's TSH-R was normal. We also report the sex ratio of hypothyroid newborns referred to our center since 1989 with apparent athyreosis (5 girls, 7 boys) and with ectopic thyroid tissue (41 girls, 15 boys). We conclude that different genetic and nongenetic mechanisms for athyreosis and ectopic thyroid are likely, and that these two distinct entities are themselves heterogeneous. Our results further show that inactivating mutations in TSH-R may account for some cases of apparent congenital athyreosis and should be suspected, especially if plasma thyroglobulin levels are normal.
Metallabis(dialkylphosphito)‐Einheiten als Komplexbildner, VI. Darstellung und Komplexbildungsvermögen des metallorganischen Chelatliganden {C5Me5RhI[P(O)(OMe)2]2}− (1990)

Complexes Containing Metallabis(dialky1phosphito) Units, VI 1 . – Synthesis and Complex‐Forming Properties of the Organometallic Chelating Ligand {C 5 Me 5 RhI[P(0)(OMe) 2 ] 2 }‐ The dinuclear complexes [C 5 Me 5 NiBr] 2 and [C 5 Me 5 RhI 2 ] 2 react stepwise with P(OMe) 3 by cleavage of the halide bridges and a subsequent Michaelis‐Arbuzov‐type reaction to give the neutral compounds C 5 Me 5 Ni[P(O)(OMe) 2 ][P(OMe) 3 ] ( 3 ) and C 5 Me 5 RhI[P(O)(OMe) 2 ][P(OMe) 3 ( 6 ). Treatment of 6 with an equimolar amount of NaI gives the sodium salt of the {C 5 Me 5 RhI[P(O)(OMe) 2 ] 2 } − anion Na[L] ( 7 ) isolated as an adduct with 0.6 NaI. Reaction 7 with H 2 SO 4 in water leads to the formation of the protonated complex C 5 Me 5 RhI[P(O)(OMe) 2 ][P(OH)(OMe) 2 ] ( 8 ), from which on treatment with thallium acetylacetonate C 5 Me 5 RhI[P(O)(OMe) 2 ] 2 TI ( 9 ) is obtained. The X‐ray structural analysis of 9 reveals that the organometallic anion L − is coordinated as a bidentate ligand by the P = O oxygen atoms to thallium, L − also behaves as a bidentate chelating ligand in the complexes [L] 2 Mg(OH 2 ) 2 ( 12 ), [L] 2 Zn ( 13 ) and [L] 2 UO 2 ( 14 ), whereas it is presumably coordinated as an O,O′,I‐tripod ligand in the compounds [L]PtMe 3 ( 10 ) and [L] 2 Cu ( 11 ). In acid solution 8 reacts with NaBPh 4 to give the diphenylborane derivative LBPh 2 ( 15 ).

A Robust Steering Assistance System for Road Departure Avoidance (2012)

A driver-assistance system (DAS) that combines an automatic road departure avoidance (RDA) system with the driver's steering input is presented. The system is based on a closed-loop driver decision estimator (DDE), which establishes the risk of road departure. If a road departure is likely to occur, the RDA system intervenes by correcting the steering angle. Robustness is guaranteed by an <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</i> <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">inf</sub> controller designed to take into consideration the main uncertainties affecting the dynamics. Driver-in-the-loop tests evaluate the performance of the system in terms of robustness, risk of road departure, and driving experience. Experiments show that the system is effective in reducing the risk of road departure without impeding maneuverability.
Calibration of Breech Erosion Gage for 5.56mm Chrome-Plated Bores (1975)

Abstract : A firing test was conducted to provide a data base for the optimization of the design of a breech erosion gage for 5.56mm chrome plated rifle barrels. Nine separate gage diameters, 27 barrels, three rates of fire, two types of ammunition and three barrel manufacturers were represented in the test to give the broadest possible data base. Analysis of the firing test led to the determination that the optimum gage diameter range is from .2210 - .2218 in, and that barrels should be rejected when gages within this diametrical range penetrate more than 2.62 in beyond the rear of the locking lugs on the barrel.

An essential role for Wnt/β-catenin signaling in mediating hypertensive heart disease (2018)

Activation of the renin-angiotensin system (RAS) is associated with hypertension and heart disease. However, how RAS activation causes cardiac lesions remains elusive. Here we report the involvement of Wnt/β-catenin signaling in this process. In rats with chronic infusion of angiotensin II (Ang II), eight Wnt ligands were induced and β-catenin activated in both cardiomyocytes and cardiac fibroblasts. Blockade of Wnt/β-catenin signaling by small molecule inhibitor ICG-001 restrained Ang II-induced cardiac hypertrophy by normalizing heart size and inhibiting hypertrophic marker genes. ICG-001 also attenuated myocardial fibrosis and inhibited α-smooth muscle actin, fibronectin and collagen I expression. These changes were accompanied by a reduced expression of atrial natriuretic peptide and B-type natriuretic peptide. Interestingly, ICG-001 also lowered blood pressure induced by Ang II. In vitro, Ang II induced multiple Wnt ligands and activated β-catenin in rat primary cardiomyocytes and fibroblasts. ICG-001 inhibited myocyte hypertrophy and Snail1, c-Myc and atrial natriuretic peptide expression, and abolished the fibrogenic effect of Ang II in cardiac fibroblasts. Finally, recombinant Wnt3a was sufficient to induce cardiomyocyte injury and fibroblast activation in vitro. Taken together, these results illustrate an essential role for Wnt/β-catenin in mediating hypertension, cardiac hypertrophy and myocardial fibrosis. Therefore, blockade of this pathway may be a novel strategy for ameliorating hypertensive heart disease.
High-Speed Ellipsometer For Thin-Film Deposition Monitoring (1989)

A conceptual design for a no-moving-parts ellipsometer with a calibration procedure to remove effects of imperfect components and detector sensitivity differences is described. The device is particularly useful for infrared (IR) coating monitoring, where high deposition rates are used and where detectors may be polarization-sensitive. A calibration scheme that uses only linearly polarized beams and no retardation components has been devised.

Abstract 2936: Obesity and Mortality in Patients with Heart Failure and Preserved Systolic Function (2008)

Several large cohort studies document better survival in heart failure patients with decreased left ventricular ejection fraction (EF) and higher body mass index (BMI) compared to those with a lower BMI. It is unclear, though, if this “obesity paradox” applies to heart failure patients with preserved EF or if it extends to the very obese (BMI&gt;35). We followed 1,235 consecutive patients with a prior diagnosis of heart failure and a preserved EF (≥50%) documented on echocardiography at one of three laboratories. We determined adjusted mortality and readmission rates at 1 year following the echocardiogram. Obesity (BMI&gt;30) was noted in 542 patients (44%). The mean age of the cohort was 71 years, but this varied depending on BMI (73 years for BMI&lt;25, 64 years for BMI&gt; 35, p&lt; 0.001). In a subset of patients with complete diastolic indices and LV mass measurements (n=405), 95% had objective evidence of diastolic dysfunction. Age-adjusted all-cause mortality (Figure ) at one year decreased with increasing BMI (31% if BMI &lt; 25, 22% if BMI 25–29, 20% if BMI 30–35 and 19% if BMI&gt;35, p=0.003). In a proportional hazards analysis that adjusted for patient history, demographics and laboratory values, the hazard ratios for total mortality (relative to a normal BMI) were 1.47 (95% CI, 1.06–2.05) for BMI&lt;25, 0.95 (95% CI, 0.64 –1.42) for BMI 30 –35, and 0.83 (95% CI, 0.52–1.31), for BMI &gt;35, p=0.046). Similar findings were noted for the composite endpoint of survival free from heart failure hospitalization. These data suggest that the obesity paradox applies to heart failure patients with preserved systolic function and extends to very obese patients (BMI&gt;35).
Colonization factors of Campylobacter jejuni in the chicken gut (2011)

Campylobacter contaminated broiler chicken meat is an important source of foodborne gastroenteritis and poses a serious health burden in industrialized countries. Broiler chickens are commonly regarded as a natural host for this zoonotic pathogen and infected birds carry a very high C. jejuni load in their gastrointestinal tract, especially the ceca. This eventually results in contaminated carcasses during processing. Current intervention methods fail to reduce the colonization of broiler chicks by C. jejuni due to an incomplete understanding on the interaction between C. jejuni and its avian host. Clearly, C. jejuni developed several survival and colonization mechanisms which are responsible for its highly adapted nature to the chicken host. But how these mechanisms interact with one another, leading to persistent, high-level cecal colonization remains largely obscure. A plethora of mutagenesis studies in the past few years resulted in the identification of several of the genes and proteins of C. jejuni involved in different aspects of the cellular response of this bacterium in the chicken gut. In this review, a thorough, up-to-date overview will be given of the survival mechanisms and colonization factors of C. jejuni identified to date. These factors may contribute to our understanding on how C. jejuni survival and colonization in chicks is mediated, as well as provide potential targets for effective subunit vaccine development.
Palladium-Catalyzed Synthesis of Diaryl Ketones from Aldehydes and (Hetero)Aryl Halides via C–H Bond Activation (2018)

We developed a palladium-catalyzed C–H transformation that enabled the synthesis of ketones from aldehydes and (hetero)aryl halides. The use of picolinamide ligands was key to achieving the transformation. Heteroaryl ketones, as well as diaryl ketones, were synthesized in good to excellent yields, even in gram-scale, using this reaction. Results of density functional theory (DFT) calculations support the C–H bond activation pathway.
3PT103 Bending stiffness of double-stranded DNA measured by winding single-molecule on a nanometer-sized reel(The 50th Annual Meeting of the Biophysical Society of Japan) (2012)

Nucleosome is a basic unit ofchromatin structuTe in which DNA duplex wraps about 1 and 3t4 times around histone octamer, Po]y-nuc[eosome takes higher order chromatin stmcture to store the very long genome into compact space. On the other hand, nucleosome is needed to be unstmctured dynamically for function; reeognized by transcription factor and trunscription to mRNA, Recently, many exper{ments have investigated mono-nucleosome dynamics. Unwrapping of DNA duptex from histone oetamer is observed by equitibrium and force unwrapping experiments. We simulate thesc nuc]eosome dynamics by using coarse-grained DNA-protein modet, in which one amino aeid is represented by one bead and one nuc[eetide is represented by three beads corresponding to phosphate, sugar, and base. Simulation results reproduce partiallfu]1 unwrapping of DNA. We also simulate rnodel poty-nuc]eosome systems to investigate higher-order structure of chromatin.

IL-17A and TNF-α Increase the Expression of the Antiapoptotic Adhesion Molecule Amigo-2 in Arthritis Synoviocytes (2016)

Rheumatoid arthritis (RA) is a chronic inflammatory disorder, characterized by a persistent immune cell infiltrate in the synovium accompanied by high levels of inflammatory mediators and synovial hyperplasia. Despite significant therapeutic advances, RA remains an important unmet medical need. To discover potential new genes controlling inflammation and apoptosis in synoviocytes, genes induced by the two pro-inflammatory cytokines, tumor necrosis factor α (TNF-α) and interleukin 17A (IL-17A), were systematically searched. We identified Amphoterin-induced gene and ORF 2 (Amigo-2), a novel antiapoptotic adhesion molecule, as synergistically upregulated by the IL-17A/TNF combination specifically in RA synoviocytes. In addition, when RA synoviocytes were cocultured with immune cells, Amigo2 expression was significantly increased in both fibroblasts and immune cells. This induction persisted in RA synoviocytes even after the removal of the immune cells. Amigo2 induction was ERK-dependent and on the contrary, inhibited by JNK. Furthermore, Amigo2 expression levels correlated with apoptosis of the cells when exposed to the proapoptotic agent cadmium (Cd). Interestingly, exposure of the cells to HMGB1 in inflammatory conditions increased synergistically Amigo2 expression and significantly reduced Cd-mediated cellular toxicity. Our findings support a model whereby cell-cell contact with immune cells and exposure to the combination of both inflammatory cytokines and HMGB1 in the joints of RA patients increases Amigo2 expression in synoviocytes in an ERK-dependent manner which, in turn, enhances cellular adhesion and promotes cell survival and cellular proliferation.
Why is Recycling of Postconsumer Plastics so Challenging? (2021)

The ubiquitous use of plastics has been driven by their combination of low cost and properties, but these attributes directly challenge waste management schemes for plastic recycling. Some postconsumer recycling programs are now nearly 50 years old, but a significant fraction of plastics still finds landfills or other dumping strategies at their end of life. With the growing concern regarding plastic waste, especially ocean plastics, there is a need for innovation and alternative strategies for the economic translation of plastic waste to valued product(s) that will promote their efficient circular utilization. This review first describes the technical and economic hurdles associated with the recycling of postconsumer plastics, but then it focuses on providing an overview of emergent strategies to recover plastic waste through new polymer design, new recycling processes, and chemical transformations to value-added products. Specific challenges discussed include plastic waste sorting and separations, product variability including additives, and the high efficiency/low cost in which the existing petrochemical industry can produce virgin polymers, in particular polyolefins. Although a wide variety of technical strategies have been demonstrated for recycling of plastics through both mechanical and chemical means, the commercial success of these different strategies is generally limited by either performance, including large variance in key metrics, or economics where the products can match the performance of virgin materials but the recycling process is expensive. Successful capture of postconsumer plastic waste through recycling likely will depend on economic incentives and government regulations.
Diffusional shunting in the canine myocardium. (1981)

A test for the existence of a diffusional shunt in the myocardium was performed in closed-chest, chloralose-anesthetized dogs. Coronary blood flow was varied from 0.21 to 1.17 ml/min per g with a roller pump via a stainless steel coronary perfusion cannula. Following intracoronary artery bolus indicator injection, the coronary sinus venous appearance times of hydrogen, plasma protein labeled with indocyanine green dye, and red blood cells labeled with 99mTc were measured. Venous appearance time was calculated, either as the time from injection until the indicator reached 5% of its peak venous concentration or the time from injection until 0.1% of the injected material arrived at the coronary sinus. At low coronary flow rates (0.4 sec dye appearance time) hydrogen appearance preceded by about 1 second the appearance of the intravascular 99mTc-labeled red blood cells and the dyed plasma, indicating that hydrogen traversed an extravascular shunt path from small arteries to veins. As flow was increased, this hydrogen precession was reduced, and at high flows detectable levels of hydrogen arrived in the coronary sinus after the intravascular indicators. The difference in appearance time between hydrogen and the intravascular indicators was related linearly to the dye appearance time (proportional to l/flow), as would be expected with diffusional shunting. These data indicate that there is arterial-venous shunting of hydrogen in the myocardium. Furthermore, diffusional shunting may be important in the delivery of oxygen to, or removal of carbon dioxide from, the heart.
C1 units for scene classification (2008)

In this paper, we unify C1 units and the locality preserving projections (LPP) into the conventional gist model for scene classification. For the improved gist model, we first utilize the C1 units, intensity channel and color channel of color image to represent the color image with the high dimensional feature, then we project high dimensional samples to a low dimensional subspace via LPP to preserve both the local geometry and the discriminate information, and finally, we apply the nearest neighbour rule with the Euclidean distance for classification. Experimental results based on the USC scene database not only demonstrate that the proposed gist improves the classification accuracy around 7% but also reduce the testing cost around 50 times in comparing with the original gist model proposed by Siagian and Itti in TPAMI 2007.
On the role of abnormal DLCOin ex-smokers without airflow limitation: symptoms, exercise capacity and hyperpolarised helium-3 MRI (2013)

In ex-smokers with normal spirometry and CT but abnormal DLCO, there were significantly worse symptoms, 6MWD and (3)He ADC compared with ex-smokers with normal DLCO, providing evidence of the impact of mild or early stage emphysema and a better understanding of abnormal DLCO and hyperpolarised (3)He MRI in ex-smokers without COPD.
